Description:
COOKER WITH VAPOR GENERATOR

FIELD OF THE INVENTION

[0001] This application relates to a cooker.

BACKGROUND OF THE INVENTION [0002] Currently, gas cookers and electric cookers have been widely used as household kitchen utensils, and brought great convenience for people's daily life.

[0003] With the continuous improvement of quality of people's life, daily meals are desired to include food of a variety of different flavors. For example, it is desired that the breakfast includes fried eggs, fried bacon, stir fried dishes, porridge, steamed breads, steamed eggs, etc., which requires using at least frying, stir frying, boiling, steaming and other different cooking methods to deal with different ingredients. However, commonly used household cookers typically include only one or two heating assemblies. For example, commonly used household gas stoves typically include only one or two gas burner assemblies, and commonly used household induction cookers typically include only one or two induction cooker hotplates. Therefore, when it requires to cook different foods by more than two different cooking methods, the commonly used household cookers sometimes cannot meet the demand. Especially in the pursuit of a healthy lifestyle, people need to cook food by "steaming" more and more. However, since "steaming" is to use heating power of water vapor to heat food, it often needs to occupy a gas burner assembly or an induction cooker hotplate for a long time, and "boiling" which also needs to take a long time will have to share the other gas burner assembly or induction cooker hotplate with cooking methods such as "frying", "stir frying", "deep frying", thus resulting in a prolonged cooking time. As the pace of people's life becomes faster and faster, in the case of short of time, the extension of cooking time will undoubtedly bring great trouble to users, and the users even have to give up the healthy nutrition steamed food which needs to take a long cooking time, and are forced to remain stagnant on the road of pursuing a healthy life.

[0004] In addition, cooking the food by steaming requires the preparation of additional pots, which requires additional placement space. In the case of limited kitchen space, the storage of pots will also cause additional distress to the users. In addition, the hot steaming pot removed from the stove will possibly scald the user.

[0005] Therefore, there is a further room for improvement in the current commonly used household cookers in terms of their functionality.

[0055] In the exemplary embodiment shown in Fig. 1, the first control devices 21, 23 and the second control device 22 are provided separately. Thus, the first control devices and the second control device are capable of independently controlling the heating assemblies and the vapor generation assembly, thereby further enhancing the flexibility of use of the cooker.

[0056] In the exemplary embodiment shown in Fig. 1, the vapor generation assembly 15 is arranged between the two gas burner assemblies 13, 14 and, as shown in Fig. 2, the vapor generation assembly 15 is arranged such that a center O15 of the vapor generation assembly 15 is offset by a distance w from a line of centers O13-O14 of the gas burner assembly 13 and the gas burner assembly 14 in the front-rear direction of the cooker 1. Preferably, the entire vapor generation assembly 15 is located on an upper side of the line of centers O13-O14, i.e., on a side opposite to the side where the control device 22 is located. It is further preferred that an outer profile of the vapor generation assembly 15 may be tangent to the line of centers O13-O14 to make use of the space between the gas burner assemblies 13, 14 as much as possible to provide the vapor generation assembly 15 having a dimension as large as possible.

[0057] In this application, the term "center" refers to a geometric center of an outer contour, presented in the top view of the cooker 1, of the relevant assemblies seen from a position over the cooker 1. The term "line of centers" refers to a virtual line connecting the "centers" of the two assemblies.

[0058] According to the above-described exemplary configuration of the cooker 1 shown in Fig. 1, by making the center of the vapor generation assembly 15 be offset from the line of centers O13-O14 of the gas burner assemblies 13, 14 by the distance w, the vapor generation assembly 15 is arranged between the gas burner assembly 13 and the gas burner assembly 14, but is not arranged side by side with the gas burner assembly 13 and the gas burner assembly 14. It will be understood that the embodiment illustrated is a preferred exemplary embodiment of the present application. The vapor generation assembly 15 may also be arranged side by side with the gas burner assembly 13 and the gas burner assembly 14.

[0059] Fig. 6 schematically shows sub-regions of an internal structure of the bottom frame 12 of the cooker 1 according to the exemplary embodiment of the present application. As shown in Fig. 6, the vapor generation assembly 15 is arranged within a sub-region 125 of the cooker 1 in which the gas burner assembly 13 and the gas burner assembly 14 are not arranged, without occupying a sub-region 122 for mounting the control devices, a sub-region 123 for mounting the gas burner assembly 13, and a sub-region 124 for mounting the gas burner assembly 14.

[0060] This arrangement of the vapor generation assembly 15 can make full use of the structural space of the cooker so as to realize the functional extension of the cooker without increasing the size of the cooker. In addition, various heat sources such as the gas burner assemblies 13, 14 and the vapor generation assembly 15 can be reasonably arranged to avoid mutual interference of the cooking utensils while contributing to the compactness of the entire cooker. Particularly, it is possible to add a vapor generation assembly without the need for an excessive modification of an existing cooker.

It may be understood that the control devices 21 ', 23' as the first control devices of the present application and the control device 22' as the second control device of the present application may be control devices of any configurations known in the art for controlling the respective components so as to adjust the power thereof. For example, they may be knob type or push button type control devices. Therefore, the description of the specific structures of the control devices is omitted here. [0067] Similar to the exemplary embodiment shown in Fig. 2, in an exemplary embodiment shown in Fig. 10, the vapor generation assembly 15 is arranged between the two electric heating assemblies 13' and 14', and the vapor generation assembly 15 is arranged such that the center O15 of the vapor generation assembly 15 is offset by a distance w' from a line of centers Oi3'-Oi4' of the electric heating assembly 13' and the electric heating assembly 14'. In this manner, the vapor generation assembly 15 is arranged between the electric heating assembly 13 ' and the electric heating assembly 14', but not side by side with the electric heating assembly 13 ' and the electric heating assembly 14'. Preferably, the entire vapor generation assembly 15 is located on an upper side of the line of centers Oi3'-Oi4', that is, on a side opposite to the side where the control device 22' is located. It is further preferred that, similar to the example as shown in Fig. 2, the outer profile of the vapor generation assembly 15 may be tangent to the line of centers Oi3'-Oi4' to make use of the space between the electric heating assembly 13' and the electric heating assembly 14' as much as possible to provide the vapor generation assembly 15 having a dimension as large as possible. [0068] According to an exemplary embodiment of the present application, the vapor generation assembly 15 may also be arranged such that a projection position P of the center O15 of the vapor generation assembly 15 on the line of centers Oi3'-Oi4' of the electric heating assembly 13 ' and the electric heating assembly 14' is coincident with a midpoint position M of the line of centers Oi3'-Oi4', or the projection position P of the center O15 of the vapor generation assembly 15 on the line of centers Oi3'-Oi4' of the electric heating assembly 13' and the electric heating assembly 14' is offset by a distance 1 from the midpoint position M of the line of centers Oi3'-Oi4' as shown in Fig. 10.

[0069] It should be noted that "the projection position of the center O15 of the vapor generation assembly 15 on the line of centers Oi3'-Oi4' of the electric heating assembly 13 ' and the electric heating assembly 14"' refers to an intersection point position between a perpendicular line extending from the center O15 of the vapor generation assembly 15 to the line of centers Oi3'-Oi4' of the electric heating assembly 13 ' and the electric heating assembly 14' and the center line Oi3'-Oi4' as observed in a top view of the cooker.

[0070] By setting the projection position P of the center O15 of the vapor generation assembly 15 on the line of centers Oi3'-Oi4' of the electric heating assembly 13' and the electric heating assembly 14' to be coincident with the midpoint position M of the line of centers O13 -O14', the vapor generation assembly 15 may be arranged to have a substantially equal distance from the two electric heating assemblies. By setting the projection position P of the center O15 of the vapor generation assembly 15 on the line of centers Oi3'-Oi4' of the electric heating assembly 13 ' and the electric heating assembly 14' to be offset by a distance from the midpoint position M of the line of centers Oi3'-Oi4', the vapor generation assembly 15 may be arranged to have a distance from one of the electric heating assemblies greater than the distance from the other electric heating assembly. In the exemplary embodiment shown in Fig. 10, the vapor generation assembly 15 is arranged to have a distance from the electric heating assembly 13 ' greater than the distance from the electric heating assembly 14'. In other words, in the left- right direction of the cooker, the center O15 of the vapor generation assembly 15 may be arranged closer to the center O13' of the electric heating assembly 13 ' or to the center Oi 4 ' of the electric heating assembly 14'. Particularly, in the case that the power of the electric heating assembly 13 ' is greater than the power of the electric heating assembly 14', the center O15 of the vapor generation assembly 15 may be arranged closer to the center Oi 4 ' of the electric heating assembly 14' in a left-right direction of the cooker, to thereby further optimizing the space utilization of the cooker.

[0071] It may be understood that in the cooker 1 provided with two gas heating assemblies as shown in Fig. 2, the projection position of the center O15 of the vapor generation assembly 15 on the line of centers O13-O14 of the two gas heating assemblies may also be coincident with the midpoint position of the line of centers O13-O14, or the projection position of the center O15 of the vapor generation assembly 15 on the line of centers O13-O14 of the two gas heating assemblies may be offset from the midpoint position of the line of centers O13-O14 to thereby arranging the vapor generation assembly 15 to have a distance from one of the gas heating assemblies greater than the distance from the other gas heating assembly. [0072] According to the above-described exemplary configuration, the vapor generation assembly 15 can be arranged away from a heating assembly having a higher heating power including a gas heating assembly and an electric heating assembly, so as to avoid non-uniform heat effect caused by this heating assembly to the vapor generation assembly.

[0073] Although in the illustrated embodiment, the vapor generation assembly 15 is arranged to be located between the two heating assemblies (for example, the two gas burner assemblies 13 and 14, or the two heating assemblies 13' and 14'), however, it may be understood that, in an embodiment not illustrated, the vapor generation assembly 15 may be arranged on the cooker 1 at a left side or a right side of the cooker 1, to allow the center of one (for example, the gas heating assembly 13) of the two gas heating assemblies 13 and 14 to be offset from a line of centers of the vapor generation assembly 15 and the other gas heating assembly (for example, the gas heating assembly 14) in the front-rear direction of the cooker 1, and/or to allow a projection position of the center of the one gas heating assembly (for example, the gas heating assembly 13) on the line of centers of the vapor generation assembly 15 and the other gas heating assembly (for example, the gas heating assembly 14) to be coincident with a midpoint position of the line of centers of the vapor generation assembly 15 and the other gas heating assembly (for example, the gas heating assembly 14) or be offset from the midpoint position of the line of centers of the vapor generation assembly 15 and the other gas heating assembly (for example, the gas heating assembly 14) in a left-right direction of the cooker 1. In addition, it may be understood that, in an embodiment not illustrated, the vapor generation assembly 15 may be arranged on the cooker at a left side or a right side of the cooker 1 ', to allow the center of one (for example, the electric heating assembly 13 ') of the two electric heating assemblies 13' and 14' to be offset from a line of centers of the vapor generation assembly 15 and the other electric heating assembly (for example, the electric heating assembly 14') in the front-rear direction of the cooker , and/or to allow a projection position of the center of the one electric heating assembly (for example, the electric heating assembly 13') on the line of centers of the vapor generation assembly 15 and the other electric heating assembly (for example, the electric heating assembly 14') to be coincident with a midpoint position of the line of centers of the vapor generation assembly 15 and the other electric heating assembly (for example, the electric heating assembly 14') or be offset from the midpoint position of the line of centers of the vapor generation assembly 15 and the other electric heating assembly (for example, the electric heating assembly 14') in a left-right direction of the cooker .

[0074] Although in the illustrated exemplary embodiments, the cookers 1, ; respectively include two gas heating assemblies and two electric heating assemblies, it may be understood that the cooker according to the present application may also be configured as including both a gas heating assembly and an electric heating assembly, and including control devices for controlling the respective gas heating assembly and the electric heating assembly to adjust their powers, respectively, which will not be described here. Particularly, the vapor generation assembly 15 is preferably provided (e.g., in the left-right direction and/or the front-rear direction) closer to the electric heating assembly in the case that the cooker includes both a gas heating assembly and an electric heating assembly. [0075] Next, the structure of the vapor generation assembly is described with reference to Figs. 7 to 9. Fig. 7 shows a top view of an exemplary embodiment of the vapor generation assembly according to the present application. Fig. 8 shows a side view of the vapor generation assembly shown in Fig. 7. Fig. 9 shows a sectional view of the vapor generation assembly taken along the cross-section C-C in Fig. 7.

[0076] In the illustrated exemplary embodiment, the vapor generation assembly 15 includes a container 151 and a heating device 152 attached to the bottom of the container 151. The heating device 152 is configured to heat the water contained in the container 151 to generate water vapor.

[0077] According to an exemplary embodiment of the present application, the heating device 152 of the vapor generation assembly 15 may be a resistive heating device or an inductive heating device.

[0078] In the illustrated exemplary embodiment, the heating device 152 of the vapor generation assembly 15 is a heating disk having a flat upper surface. The container 151 of the vapor generation assembly 15 is a substantially cylindrical member. At the bottom of the container 151, a recess 1516 is formed which is recessed toward the inside of the container 151. The heating device 152 is accommodated in the recess 1516 at the bottom of the container 151, and a flat upper surface of the heating device 152 engages with a flat surface located at the bottom of the recess 1516 to heat the water contained in the container 151 by heat conduction when the heating device 152 generates heat to produce water vapor. Preferably, the container 151 of the vapor generation assembly 15 is made of a metal material having good thermal conductivity such as stainless steel.

[0079] According to an exemplary embodiment of the present application, the heating device 152 of the vapor generation assembly 15 may be molded together with the container 151 into an integral part, or the heating device 152 may be detachably attached to the bottom of the container 151 to be formed together with the container 151 into an integral part.

[0080] Modular management of the vapor generation assembly 15 can be realized by forming the heating device 152 and the container 151 of the vapor generation assembly 15 into the integral part. When the vapor generation assembly 15 needs to be removed from the cooker 1, 1 ' due to maintenance or replacement, the vapor generation assembly 15 can be removed by a single action without requiring removal of multiple separate parts of the vapor generation assembly 15 from the cooker 1. Similarly, when the vapor generation assembly 15 is assembled to the cooker 1, 1 ', it can be placed and positioned by a single action. Thus, the installation and assembly of the vapor generation assembly 15 is made simple. [0081] Referring to Figs. 7 and 9, in the illustrated exemplary embodiment, the container 151 of the vapor generation assembly 15 includes a bottom wall 1511, a peripheral wall 1512 extending angularly with respect to the bottom wall 1511 from a peripheral edge of the bottom wall 1511 in a height direction of the container 151, and a flange 1513 extending radially outwards from a peripheral edge, at an end opposite to the end where the bottom wall 1511 is located, of the peripheral wall 1512. The peripheral edge, at the end opposite to the end where the bottom wall 1511 is located, of the peripheral wall 1512 forms an inner edge 1515 of the flange 1513.

[0082] In the illustrated exemplary embodiment, the peripheral wall 1512 of the container 151 extends angularly with respect to the bottom wall 1511 from the peripheral edge of the bottom wall 1511 upwards and radially outwards so that the container 151 is formed into a flared shape gradually enlarged from its bottom to opening.

[0083] In this way, the size of the heating device 152 can be reduced while a larger vapor outlet is obtained, thereby achieving an efficient food steaming function while saving energy. In addition, the configuration, tapered toward the bottom, of the container 151 also facilitates cleaning and maintenance of the inside of the container. [0084] In the embodiment according to the present application, the bottom wall 1511, the peripheral wall 1512 and the flange 1513 of the container 151 are each applied at an inner side thereof with a coating of a special material (for example, a polytetrafluoroethylene coating) to facilitate cleaning and maintenance of the inside of the container 151.

[0085] In the illustrated exemplary embodiment, the flange 1513 of the container 151 of the vapor generation assembly 15 is configured such that, in the height direction of the container 151, a distance hi of an outer edge 1514 of the flange 1513 from the bottom wall 1511 of the container 151 is greater than a distance h2 of the inner edge 1515 of the flange 1513 from the bottom wall 1511 (hl>h2).

[0086] According to the above configuration, with respect to the bottom wall 1511, the outer edge 1514 of the flange 1513 of the container 151 is higher than the inner edge 1515 of the flange 1513 in the height direction of the container 151. In this way, it is possible to prevent the water in the container 151 from escaping from the container 151 when being heated and boiling, to facilitate the natural return of the water flowing onto the flange 1513 of the container 151 into the container 151.

[0087] Referring to Figs. 4 and 5, in the illustrated exemplary embodiment, the vapor generation assembly 15 is attached to the top panel of the cooker 1 by the flange 1513 of the container 151.

[0088] According to an embodiment of the present application, a sealing member (not illustrated) may be provided between the flange 1513 of the container 151 of the vapor generation assembly 15 and the top panel 11 of the cooker 1. In the embodiment according to the present application, the sealing member provided between the flange 1513 of the container 151 and the top panel 11 of the cooker 1 is made of a heat-resistant material.

[0089] It may be understood that in the exemplary embodiment shown in Fig. 10, the vapor generation assembly 15 may be attached to the top panel 11 Of the cooker 1 ' by the flange 1513 of the container 151 in a similar manner.

[0090] According to the above-described configuration, by providing the sealing member between the container flange 1513 of the vapor generation assembly 15 and the top panel 11, 11 ' of the cooker 1, 1 ', the water on the top panel 11, 11 ' of the cooker 1, , for example, the water spilled onto the top panel 11, 11 ' during injecting water into the container 151 of the vapor generation assembly 15, may be prevented from being leaked into the inside of the cooker 1, 1 ' and adversely affecting the normal operation of electronic elements arranged inside the cooker accordingly.

[0091] According to an embodiment of the present application, the cooker 1, may further include at least one steamer tray (not illustrated). A lower end portion of the steamer tray is configured to be positively engaged with the flange 1513 of the container 151 of the vapor generation assembly 15.

[0092] According to an exemplary embodiment of the present application, a stepped portion 1517 is provided at a position, near the outer edge 1514, of the flange 1513 of the container 151 of the vapor generation assembly 15. As shown in Fig. 9, one end, adjacent to the outer edge 1514, of the stepped portion 1517 is higher than one end, adjacent to the inner edge 1515, of the stepped portion 1517 in the height direction of the container 151.

[0093] In this way, the stepped portion 1517 may be formed with an engagement portion positively engaged with the lower end portion of the steamer tray. In addition, the stepped portion 1517 can also function as a stopper for restricting the movement of the steamer tray.

[0094] According to the above-described configuration, the function of the cooker 1, 1 ' is further extended by providing the at least one steamer tray for the cooker 1, . It is possible to ensure the thermal efficiency of the vapor generation assembly and to ensure that the distilled water flowing from the side wall of the steamer tray naturally returns into the container by configuring the lower end portion of the steamer tray to be positively engaged with the flange 1513 of the container 151 of the vapor generation assembly 15.

[0095] In the above embodiment, the vapor generation assembly 15, in particular the container 151, is fixedly arranged in the cooker, but it can be envisaged by the person skilled in the art that the vapor generation assembly 15, in particular the container 151, may be easily detachably arranged in the cooker, to facilitate cleaning. For example, the heating device 152 of the vapor generation assembly 15 may be fixedly connected to the frame 12 or the panel 11 of the cooker, and the container 151 may be designed to be independent from the heating device 152 and to be easily removed from the cooker for cleaning.

[0096] It will be understood that, the vapor generation assembly 15 is not limited to the specific configuration illustrated, but may have various configurations. For example, though in the illustrated embodiment, the container 151 of the vapor generation assembly 15 has a substantially flat bottom wall, it may be understood that, the bottom wall of the container of the vapor generation assembly 15 may also be provided with a protrusion protruding towards the opening of the container and configured to accommodate of the heating device, and a groove for storing water arranged to surround the protrusion, so as to facilitate the generation of vapor.

[0097] According to an embodiment of the present application, the vapor generation assembly 15 may further include an automatic power-off device (not illustrated) configured to shut off the power supply of the heating device 152 when water shortage in the container 151 occurs in the case that the vapor generation assembly 15 is in a working state. [0098] It may be understood that in the embodiments of the cooker 1, 1 ' according to the present application, the automatic power-off device of the vapor generation assembly 15 can be properly selected according to the specific type (the resistive heating device or the inductive heating device) of the heating device 152. The structure of such an automatic power-off device is known per se and is not described here.

[0099] In some embodiments according to the present application, the vapor generation assembly 15 may further be provided with an automatic alarm device used with the automatic power-off device or independently used and configured to alarm the user when water shortage in the container 151 occurs in the case that the vapor generation assembly 15 is in the working state. The structure of such an automatic alarm device is known per se and is not described here.

[00100] In some embodiments according to the present application, the vapor generation assembly 15 may further include a water level display device (not illustrated) configured to display the information of current water level in the container 151 of the vapor generation assembly 15 to assist the user in determining the water injection demand of the container 151.

[00101] By providing the automatic power-off device, the automatic alarm device and/or the water level display device for the vapor generation unit 15, it is possible to prevent the vapor generation module 15 from being overheated in the case of no water in the container 151, thus ensuring the use safety of the cooker 1, 1 '. [00102] According to the above-described configuration of the present application, by providing a freestanding vapor generation assembly independently of the conventional heating assemblies on the cooker, the cooker is enabled to have an independent function of steaming food, thus achieving functional extension of the cooker. Providing independent food steaming function for the cookers solves the contradiction between people's pursuit of healthy nutrition steamed food and short of time resulted from the faster and faster pace of life. Since the steaming process which takes a long time can be performed simultaneously with other conventional cooking methods, the cooker of the present application can be employed to cook more types of food with more cooking methods in substantially the same cooking time, and thus can meet the demand of people for improving the quality of daily life. [00103] In addition, the cooker according to the present application dispenses with a dedicated steaming pot, thereby dispensing with the placement space for placing the steaming pot, saving the kitchen space, and reducing the risk of possible scalding caused to the user by arrangement of too many heated pots.

[00104] The present application has been described hereinbefore with reference to the drawings through the description of the embodiments, and the present application is not limited to the above-described embodiments. It may be understood by the person skilled in the art that modifications and variations may be made without departing from the technical idea of the present application, and all these modifications and variations are also intended to be included within the scope of the present application.
