TECHNICAL FIELD

The invention relates to a dryer having at least one drying assembly comprising at least one air opening allowing air to be transferred into the drying chamber for moistening in order to remove at least part of the moisture from the textile product, and at least one vent through which the moistened air in the said drying chamber is passed.

BACKGROUND

Tumble dryers have become one of the indispensable elements in both domestic and industrial use. The working principle of the dryers is basically based on delivering hot air to the laundry placed in a drying chamber. The hot air dries and dehumidifies the laundry.

In the vented version of the dryers, the air sucked from the environment by the fan-snail system is first sent to the heaters. With the help of the heater, the air whose temperature rises is sent to the drum and dehumidifies the laundry. This moist air is first passed through the filter and sent to the environment with the help of a vent or to the outside of the room with the help of an additional vent. In cases where it is not possible to send the moist air coming out of the vent out of the room, the hot and moist air causes the moisture and temperature of the room to increase.

Considering the comfort conditions, when the air pumped into the environment by the machine is examined, the air that changes depending on the decrease in the moisture of the laundry, but where the relative humidity is 100%, especially in the first cycles, is delivered to the environment. The air temperatures coming out of the vent can reach 50 °C in the middle of the cycle. As a result, the comfort level in the room decreases. In addition, the hot air thrown out means that some energy is thrown out. This negatively affects the efficiency of the system.

Application No. US10494754B2, which is in the literature, relates to a tumble dryer. Accordingly, the tumble dryer comprises a heat exchanger. This heat exchanger placed in the vent provides heat transfer between the hot exhaust air and the cold fresh air. In this way, heat recovery is achieved. As a result, all the above-mentioned problems have made it necessary to make an innovation in the relevant technical field.

BRIEF DESCRIPTION OF THE INVENTION

The present invention relates to a dryer for eliminating the above-mentioned disadvantages and bringing new advantages to the related technical field.

An object of the invention is to provide a dryer in which the supply of hot air to the environment is at least partially prevented, thus maintaining the air comfort of the environment.

Another object of the invention is to provide a dryer with increased efficiency.

In order to achieve all the objects mentioned above and which will emerge from the detailed description below, the present invention is a dryer having at least one drying assembly comprising at least one air opening for allowing air to be transferred into the drying chamber for moistening in order to remove at least part of the moisture from the textile product, and at least one vent through which the moistened air in the said drying chamber is passed. Accordingly, its novelty is that in said drying assembly, the said vent is positioned in contact with the air passed through said air opening, and the vent is inclined at a predetermined angle X between them with respect to the floor so that the water obtained by at least partial condensation of the air in the vent is accumulated in a predetermined place. Thus, it is ensured that the air supplied to the environment can be cooled and its moisture reduced. In addition, while the hot air is cooling, the condensed water formed in the vent can be discharged. In addition, it is ensured that the air taken in can be preheated. In this way, a vent structure where heat recovery can be achieved is provided. However, it is ensured that the condensed moisture can be thrown out of the vent by gravity.

A possible embodiment of the invention is characterized in that it comprises at least one flap to improve the heat transfer on the vent. Thus, a larger surface area is provided for the heat transfer between the fresh air and the vent. In this way, the heat transfer surface is increased. Another possible embodiment of the invention is characterized in that the said angle X is 5°. Thus, it is ensured that the condensed water in the vent can be discharged at an optimum level.

Another possible embodiment of the invention is characterized in that the vent is in the form of a zigzag. Thus, it is ensured that the path through which the air passes becomes longer. In this way, the amount of heat transfer is increased.

Another possible embodiment of the invention is characterized in that the vent has an angle Y between it and the air opening. Thus, it is ensured that the air can pass over the vent with higher efficiency.

Another possible embodiment of the invention is characterized in that the said angle Y is 45°. Thus, it is ensured that the air can pass over the vent with maximum efficiency.

Another possible embodiment of the invention is characterized in that the air opening is positioned on an external cabin of the dryer. Thus, it is ensured that the vent can be positioned on the path of the air entering the external cabin.

Another possible embodiment of the invention is characterized in that there are 2 air openings located on the cabin, adjacent to the vent. Thus, the amount of air taken into the cabin is increased. Thus, it is ensured that the vent can perform more heat transfer.

Another possible embodiment of the invention is characterized in that the vent is associated with at least one container. Thus, it is ensured that the water discharged after condensation from the vent can be collected in a place to be removed from the dryer and the environment later on.

Another possible embodiment of the invention is characterized in that said container is on the external cabin. Thus, it is ensured that the water accumulated in the container is accessible so that it can be discharged.

Another possible embodiment of the invention is characterized in that the container is on at least one cover. Thus, it is ensured that the amount of water in the container can be monitored visually. BRIEF DESCRIPTION OF THE FIGURES

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, the subject matter of the invention is explained only by means of examples that will not have any limiting effect for a better understanding of the subject matter.

Figure 1 shows a representative side view of the dryer (10) of the invention. Accordingly, the said dryer (10) is mainly used for drying laundry and dehumidifying the laundry. The dryer (10) has at least one external cabin (11). The said external cabin (11 ) is the body of the dryer

(10). The dryer (10) comprises at least one drying assembly (20). Said drying assembly (20) provides the drying and dehumidification of the laundry. The drying assembly (20) comprises at least one drying chamber (21). Said drying chamber (21 ) is the section in which the laundry is positioned. In a possible embodiment of the invention, the drying chamber (21) can be a drum.

Figure 2 shows a representative rear view of the dryer (10) of the invention. Accordingly, the dryer (10) has at least one air opening (12). The said air opening (12) is positioned on the external cabin (11). The air opening (12) is the space provided to allow the passage of air through it. Thus, the air opening (12) provides air entry to the drying assembly (20). In a preferred embodiment of the invention, there are two air openings (12) on the external cabin

(11 ). Accordingly, one of the air openings (12) is on the surface of the external cabin (11 ) facing the floor (30). Another of the air openings (12) is on the lateral surface of the external cabin (11 ).

The dryer (10) comprises at least one cover (22). The said cover (22) is provided adjacent to the drying chamber (21). The cover (22) ensures that the opening that provides access to the drying chamber (21) can be opened and closed in order to place laundry in the drying chamber (21) or to take laundry from the drying chamber (21). The cover (22) is made of transparent material, allowing the drying chamber (21) to be observed from the outside. The drying assembly (20) comprises at least one fan-snail structure (23). Said fan-snail structure

(23) is associated with the drying chamber (21). The fan-snail structure (23) ensures that the air is sucked into the dryer (10). However, the fan-snail structure (23) ensures that the air is sent into the drying chamber (21).

The drying assembly (20) comprises at least one drive element (not shown in the figures). Said drive element provides drive to the fan-snail structure (23). However, according to a possible embodiment of the invention, the driving element also enables the drying chamber (21 ) to rotate. The drying assembly (20) comprises at least one heater (24). Said heater (24) is positioned between the fan-snail structure (23) and the drying chamber (21). The heater

(24) provides heating of the air sent into the drying chamber (21). The drying assembly (20) comprises at least one filter (25). Said filter (25) provides filtering of the air discharged from the drying chamber (21).

The drying assembly (20) comprises at least one vent (26). Said vent (26) provides air discharge from the dryer (10). Accordingly, hot, and moist air enters the vent (26) from one end of the drying chamber (21 ). The other end of the vent (26) opens to the environment where the dryer (10) is located.

The air opening (12) is located in close proximity to the vent (26). Accordingly, the vent (26) is positioned between the air opening (12) and the fan-snail structure (23). Thus, the air sucked from the air opening (12) of the fan-snail structure (23) passes around the vent (26). Thus, heat transfer takes place between the air entering through the air opening (12) and the surface of the vent (26). The hot air in the vent (26) is cooled by heat transfer. In addition, the air reaching the fan-snail structure (23) is heated. Figure 2 shows the air sucked from the environment and transferred to the drying chamber (21) with straight arrows, and the air transferred from the drying chamber (21 ) to the vent (26) with dashed arrows.

The vent (26) is positioned with at least one angle Y (Y) between them with respect to the air opening (12). Thus, according to a possible embodiment of the invention, it is ensured that the air entering from the two air openings (12) can contact the vent (26). In a preferred embodiment of the invention, said angle Y (Y) can be 45°. Thus, it is ensured that the air reaches the maximum contact surface with the vent (26) and passes into the fan-snail structure (23).

Figure 3 shows a representative side view of the vent (26) of the dryer of the invention. Accordingly, the vent (26) is provided in the form of a zigzag. Thus, the contact surface of the vent (26) with the air is increased. The vent (26) comprises at least one flap (261). Said flap (261 ) is the form that protrudes outward from the surface of the vent (26). There are multiple flaps (261) on the vent (26). The flap (261) provides an increase in the external surface area of the vent (26). Thus, the heat transfer surface is increased between the air sucked from the air opening (12) and the vent (26). In this way, the air inside the vent (26) is cooled more and the air entering through the air opening (12) is heated more.

The vent (26) is positioned with at least one angle X (X) between them with respect to the floor (30). Accordingly, the air inlet end of the vent (26) is positioned so that it remains farther from the floor (30) than the air outlet end. Thus, it is ensured that the water condensed in the vent (26) can be discharged as a result of heat transfer. In a preferred embodiment of the invention, said angle X (X) can be 5°. Thus, an optimum slope is provided for the discharge of water.

In a possible embodiment of the invention, the dryer (10) comprises at least one container (27). The said container (27) is a reservoir in a form that will allow water to accumulate in it. The container (27) is positioned adjacent to the air outlet end of the vent (26). Thus, the water condensed in the vent (26) flows out of the vent (26) and is collected into the container (27). In a possible embodiment of the invention, the container (27) is located on the external cabin (11). Thus, it is ensured that the container (27) is located in an accessible position from the outside. Thus, it is ensured that if the container (27) becomes full, it can be emptied by the user. In another possible embodiment of the invention, the container (27) can be located on the cover (22). Accordingly, the water condensed in the vent (26) can be transferred to the container (27) on the cover (22) by pumping. In this way, the container (27) is provided in a transparent structure together with the cover (22), allowing the fullness of its interior to be observed. Thus, the fullness of the container (27) can be monitored visually.

According to all these descriptions, the dryer (10) of the invention works as follows: The fansnail structure (23) provides air suction from the air opening (12). The sucked air is the cold air in the environment where the dryer (10) is located. The air reaches the fan-snail structure (23) by contacting the vent (26) and the flaps (261 ). The fan-snail structure (23) sends the air to the drying chamber (21 ) over the heater (24). The air whose temperature rises in the heater (24) provides the drying of the laundry in the drying chamber (21). However, hot air dehumidifies the laundry.

The moist and hot air in the drying chamber is then transferred to the vent (26), passing through the filter (25). Heat transfer takes place between the hot air inside the vent (26) and the cold air that is in contact with the external surface of the vent (26) and sucked from the air openings (12). As a result, the hot air in the vent (26) loses heat and cools. As a result of the cooling, the water vapor in the hot air inside the vent (26) condenses. The condensed water is discharged by flowing out of the vent (26) thanks to the positioning of the vent (26) with an angle of X (X). The discharged water accumulates in the container (27). The user can empty the container (27) when it is full.

Due to the fact that the vent (26) is positioned in contact with the air passing through the air opening (12), it is ensured that the air supplied from the vent (26) to the environment is cooled and dehumidified at least partially. In this way, it is ensured that the air comfort in the environment is maintained. However, it is ensured that the air entering the dryer (10) can be at least partially preheated by contact with the vent (26). Thus, the waste heat in the dryer (10) can be reused. As a result, a dryer (10) with increased efficiency and energy recovery is provided.

Thanks to the fact that the vent (26) is positioned inclined at a predetermined angle X (X) between them with respect to the floor (30), it is ensured that the water condensed in the vent (26) can be discharged. Thus, the water condensed in the vent (26) is provided to flow out of the vent (26) by gravity. Thus, it is ensured that the water that may remain in the vent (26) can be discharged without the need for any additional energy.

The protection scope of the invention is specified in the appended claims and cannot be limited to what has been described in this detailed description for illustrative purposes. It is clear that those skilled in the art can present similar embodiments in the light of what has been described above without departing from the main theme of the invention.
