In the prior art, cooling appliances, especially in refrigerators, when the door is opened, the cool air inside immediately replaces warm air in the environment. The cool air is entirely discharged and warm air is filled during the opening and closing of the door in 10 seconds. If the door is kept open, a permanent airflow occurs due to the effect of the cool surfaces inside and both the heat and heat/mass are transferred by means of the conveyance from surface inside and the concentration of the water steam in the surfaces.

When the door is opened, as the dry and cool air inside is replaced with the warm and humid air outside, it is loaded with heat and humidity in proportion with the extent of the volume inside. The so-called extent of this load depends on the factors like the geometry of the refrigerator (extent of the volume), the number of the shelves inside, the presence of the packaged foods and the additional cool surface area.

After the door is closed, this additional heat load is required to be discharged by the cooling system to return to the previous conditions. In this case, in comparison with the close condition of the door, compressor works for a longer duration. In case there is food inside, both the humid load and heat load exceed.

Since the kids may consider the opening and closing of the doors as a need or a game, the opening-closing number of doors of particularly families with kids rather increases.

The opening and closing of the door is not taken in to consideration in the measurement methodology of the standard energy consumption. However it

naturally affects in the real use. Therefore the producer is expected to design a low-energy consuming and more functional refrigerator in respect with not only the standard condition but also the real use conditions.

When it is handled from the easy use (ergonomics) perspective, it is observed that the consumers due to their easy use mostly prefer the shelves on the refrigerator door.

On the other hand the cool preservation of the foods is required at a rare shifting (almost stable) temperature interval from the hygienic and food quality perspective. The high level of temperature oscillations on the foods badly affects the quality of the goods. Due to the warm airflow particularly during the opening of the door, the temperatures close to the surfaces of the foods may increase and the quality and freshness of the foods may be badly affected.

When the consumers are observed, it can be viewed that fresh food compartment is mostly occupied by water/juices (especially in warm weather) and raw-consumed vegetable/fruits.

Ventilation opening Refrigerators (1) comprise a body (5) comprising at least one compartment in which the food/beverages are put, one or more refrigerator shelf (4) on which the food/beverages are put, a vegetable compartment (18) preferably under the body (5), one or more inner doors (3) closing the body (5), one or more inner door opening handle (9) providing the opening and closing of the inner door (3), one or more outer doors (2) closing the inner door (3), one or more outer door opening handle (10 providing the opening and closing of the outer door (2), one or more

inter-compartments (29) between the inner door (3) and the outer door (2), one or more hinges (12) providing the opening and closing of the inner door (3) and the outer door (2), one or more gaskets (11) closing the inner door (3) and the outer door (2) by means of entire isolation, one or more door shelves (20) in which foods/beverages are put and which can be attached and removed from the shelf projections on both the inner door (3) and the outer door (2) in a way not to force the hinges and prevent the air circulation, at least one evaporator (6) providing the cooling by means of the circulation of the refrigeration fluid, one or more fans (8) cooling the air inside by transferring it over the evaporator (6), one or more air distribution channels (7) providing the transfer of the cooled air to the required places and one or more lids (15) providing the control and the passage of the cooled air preferably in the air distribution channel (7).

Refrigerator comprises on or more funnel inlet (13) preferably on the inner door (3) providing the air flow to the inter-compartment (29) through the body (5) and one or more funnel outlets (14) providing the air flow to the body (5) through between the inner door (3) and the outer door (2).

In another embodiment of the invention, funnel inlet (13) and funnel outlet (14) are mounted on the body (5).

In order to facilitate the air circulation, door shelves (20) comprise one or more shelf ventilation openings (30).

The fans (8) provides the absorption of the heated air through inside the body (5) and the inter-compartment, the cooling of the absorbed air by transferring it over the evaporator (6) by the air distribution channel (7) and redelivering it to the lower part of the body (5). Due to the cooled air funnel inlet (13) at the lower part, the body (5) is engaged between the inner door (3) and the outer door (2) and joined to the refrigeration cycle by means of the absorption by the funnel outlet (14) and the fan (8).

The air circulation carried by means of the air distribution channel (7) is transferred to between funnel inlets (13) preferably on the inner door (3), the inner door (3) and the outer door, and included in the refrigeration cycle by being transferred from the funnel outlet (14) and the timer door (3) and the outer door (2). The transfer of the cool air into the refrigerator shelves (4) is enabled by means of the holes and valves on the air distribution channel (7). The air distribution channel (7) provides the air circulation through the upper and lower parts of the vegetable compartment (18). In a preferred embodiment of the invention, the cool air directed by means of the air distribution channel (7) is directed to the funnel inlet (13) following the circulation around the vegetable compartment (18).

The lid (15) is controlled by the data obtained for the temperature measurements from thermostat or sensor, mechanic methods or control card.

Therefore it enables to reach the required temperatures in the refrigerator (1) by turning on or off the refrigeration cycle when the temperature values obtained for the refrigerator (1) goes above or below the required values. In case the temperature of the inter-compartment goes above or below the required values, lid (15) opens or blocks the air flow to the body (5) preferably by the control card and directs the cooled air into the inter-eompartment or vice versa.

In another embodiment of the invention, refrigerator (1) comprises a funnel channel (21) directing the cool air circulation and joining the funnel inlet (13) with the funnel outlet (14) and one or more funnel blowing opening (22) on the funnel channel (21) transferring the cool air in the funnel channel (21) to the inter-compartment (29). The funnel channel (21) divides the inter-compartment into more than one compartment and they are cooled by the funnel blowing openings (22).

In another embodiment of the invention, refrigerator (1) comprises at least one funnel fan (19) preferably on the funnel inlet (13) of the inner door (3) absorbing the cool air directed from the evaporator (6) and blowing to the inter- compartment (29).

In another embodiment of the invention, refrigerator (1) comprises at least one funnel cover (17) preferably on the funnel inlet (13) of the inner door (3), a funnel cover hinge providing the movement of the funnel cover around its axis, a funnel cover spring providing the movement of the funnel cover (17) around the hinge of the funnel cover and an extensive door shelf (28) which open the funnel cover (17) by moving with itself when the outer door (2) is closed and closes the funnel cover (17) by moving with itself when it is opened.

In another embodiment of the invention, funnel cover (17) is controlled by the control card of the refrigerator (1). In this embodiment, the control card which detects the opening of the outer door (3) by means of the sensors closes the funnel cover (17) and closes the part opened by the funnel cover (17) between the inter- compartment and the body (5). Hence the transfer of heat and humidity from the body (5) is reduced. Furthermore when the temperature values in the inter- compartment (29) goes above or below the required values, the control card turns on or off the refrigeration cycle and provides the inter-compartment (29) with the required values by means of the sensors in the inter-compartment (29).

In another embodiment of the invention, refrigerator (1) comprises one or more refrigeration compartment (25) in which the foods like vegetables and fruits are stored, an inner door (3) which closes the refrigeration compartment (25), an outer door (2) which closes the inner door, one or more freeze compartment (26) in which the foods which should be kept at low temperatures like meat are stored and an outer door (2) which closes the freeze compartment. In this embodiment the refrigerator (1) comprises one or more collection channels (23) collecting the air flow and directing it to the evaporator (6) and a door cooling channel (24)

which is connected to the air distribution channel (7) distributing the cool air through the evaporator (6) to the body (5) and the funnel inlet (13) transferring the cool air to the inter-compartment (29).

In another embodiment of the invention, refrigerator (1) comprises one or more additional inter-compartment (27) preferably on the inner door (3) isolated from the other inter-compartments between the inner door (3) and the outer door (2) and an additional compartment door (16) closing the additional inter- compartment (27). The additional inter-compartment (27) is isolated from the inter-compartment by the sides of the inner door (3) and the outer door (2), funnel channel (21) and a wall engaging the runnel channel (21) with the inner and/or the outer door (2,3). Additionally the additional inter-compartment is easily isolated by means of the gasket (11) on the additional compartment door (16) closing these walls. When the additional compartment door (16) is opened, the air circulation in the inter-compartment is not affected due to this structure. If required by the user, the additional inter-compartment (27) can be used for the storage of the goods for various purposes such as foods, drugs or clothes or their kids without affecting the refrigeration cycle.

In an embodiment of the invention, refrigerator (1) is isolated by the closing of the body (5) by the gasket (11) comprising preferably magnetic material placed in a position to cover all sides of the outer door (2) on the inner surface of the outer door (2) facing with the body (5). In this embodiment, each hinge (12) is mounted on and under the outer door (2) and the outer door (2) is opened by rotating around the axis of the hinges by means of the outer door opening handle (10). In this embodiment, the inner door (3) is opened by means of the hinges (12) on the upper and lower sides independent from the outer door (2) (Fig. 6a). The inner door (3) is isolated by any gasket (11) as it does not contact with the outside of the refrigerator (1). The inner door (3) contacts with the outer environment only when the outer door (2) is opened. In this case, as the inner door (3) made of isolation material preventing the heat transfer from the body to the

outer environment, heat is transferred only through the small spaces between the sides of the inner door (3) and the inner surfaces of the body (5). The heat transfer from the outer environment to the body (5) is considerably reduced as the opening and closing duration of the outer door (2) is rather short. Therefore either the compressor is not operated or it is operated for a short while to achive the required environment conditions for the refrigeration of the body (5). In this way the energy consumption is reduced and the spoilage of the foods/beverages in the body is prevented. The problem that may arise from the isolation of the body is minimized with the use of gasket (11) only on the outer door and accordingly the additional costs for the gaskets (11) for all doors on the body (5) are avoided (Fig.

6c).

In another embodiment of the invention, the outer door (2) and the inner door (3) are opened and closed by means of the same hinges (11). In this embodiment the isolation of the spaces between the doors and the body is provided by the hinge (11) placed on the outer door (2).

In another embodiment of the invention, the outer door (2) and the inner door (3) are opened and closed by means of different hinges independent from each other. In this embodiment, the isolation of the spaces between the doors and the body is provided by the hinges (11) placed both on the inner door (3) and the outer door (2).

In another embodiment of the invention, in order to make it possible for the user to see the foods and/or beverages behind the doors, a part or the entire of the outer (2) and/or inner doors (3) opening preferably the fresh food compartment is made from transparent materials such as glass.

As the refrigerator (1) comprises more than one transparent doors (2,3), various advantages are obtained concerning the isolation in addition to the easy storage and use of the foods and/or beverages in the body (5) depending on the

request of the user due to more than one doors (2,3) and more than one compartments (25,26, 27). Therefore the spoilage of the foods/beverages, which are forgotten or not used is prevented.

By means of this invention, the access by the user to the drugs, clothes and especially frequently consumed foods/beverages placed in the compartment between the outer door (2) and the inner door (3) where the foods like fruits and vegetables and beverages are put is provided by means of only the outer door (2) for the storage of the quality of the foods with the minimum contact with the outer air. Therefore the entire or a part of the body (5) is filled with the warm and humid air and heat gained by the opening and closing of the door is minimized.

Furthermore it provides the reduction in the humid load and potential heat gain together with high performance and rare defrosting by means of low snowing on the evaporator.
