The present invention relates to a double-door refrigerator, and more particularly, to independent control of the vegetable room temperature of the double-door refrigerator to inlet the cold air in the freezer compartment to the vegetable compartment side to properly control the temperature of the vegetable compartment in a wider temperature range independently of the temperature of the refrigerator compartment It is about.

In general, a refrigerator is a home appliance used for low temperature storage of various foods, and is provided to partition a freezer compartment and a refrigerating compartment for freezing and refrigerating storage, and a front door for selective opening and closing of the freezer compartment and the refrigerating compartment is provided. .

These refrigerators are divided into upper and lower types having a freezer compartment at the top and a refrigerating compartment at the bottom, and a double door type having the freezer compartment at the left side and the refrigerating compartment at the right side. This is a more preferred trend.

In the double door refrigerator, a freezer compartment and a refrigerating compartment are formed on the left and right sides with an intermediate wall interposed therebetween, and a vegetable compartment, which is a separate storage space for storing vegetables or fruits, is formed on the lower side of the refrigerating compartment. The box is opened in the upper shape of the vegetable box is formed so that the storage space therein is provided to be pulled out and received by sliding in the front and rear direction.

Here, the vegetable compartment cover is fixed to the upper side of the vegetable compartment in the horizontal direction so as to be separated from the refrigerator compartment side.

However, in the conventional refrigerator as described above, since the vegetable compartment is formed in the refrigerating compartment, the temperature of the vegetable compartment is eventually determined according to the temperature of the refrigerating compartment, that is, the vegetable compartment has a limit in which its temperature can be adjusted only within the temperature range of the refrigerating compartment.

Therefore, regardless of the type or amount of vegetables to be stored is always cooled only by cold air within a certain temperature range, there was a problem that can not provide an optimized storage temperature environment according to the food characteristics to be stored.

That is, for example, when the amount of vegetables to be stored is large enough to prevent the decay of vegetables when stored at a lower temperature for a long time, there is a problem such as damage to the vegetables do not realize a lower temperature.

The present invention was devised to solve the above-mentioned problems, and by partially introducing the cold air of the freezer compartment into the vegetable compartment side to independently control the temperature of the vegetable compartment within a wider temperature range to optimize the temperature environment for the food storage characteristics. Its purpose is to provide a vegetable room temperature independent control device of a double-door refrigerator that can provide.

In the vegetable room temperature independent control apparatus of the double-door refrigerator of the present invention for achieving the above object, the freezer compartment and the refrigerator compartment are formed on each of the left and right sides with the intermediate wall therebetween, and the vegetable compartment is formed separately on the lower side of the refrigerator compartment in the double-door refrigerator An apparatus for independently controlling the temperature of the vegetable chamber, which is formed to penetrate the intermediate wall to control the cold air inlet hole to allow the cold air in the freezer compartment to flow into the vegetable chamber, and to control the amount of cold air introduced by opening and closing the cold air inlet hole. An electromagnetic damper, a fan for forcing cold air to flow through the cold air inlet, a cold air flow passage formed along the outside of the vegetable compartment to cool the vegetable compartment while the introduced cold air flows, and the cold air flow passage. Cold recovery passage to pass the cold air to the evaporator side It includes.

The above objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view for explaining a vegetable room temperature independent control device of a double-door refrigerator according to the present invention, Figure 2 is a schematic diagram.

According to the present invention, in order to control the temperature of the vegetable chamber 150 in a wider range, the cold air of the relatively low temperature freezer compartment 110 is introduced into the vegetable compartment 150 side, and for this purpose, the freezer compartment 110 and the refrigerating compartment ( The cold air inlet hole 132 is formed to penetrate in the horizontal direction at the lower end side of the intermediate wall 130 that partitions 120, through which the cold air of the freezer compartment 110 flows into the vegetable chamber 150 side.

In addition, a cold air flow path 160 through which the cold air introduced through the aforementioned cold air inlet hole 132 flows is formed at the outer side of the vegetable chamber 150 formed separately on the lower side of the refrigerating chamber 120. The passage 160 has the cold air introduced through the cold air inlet hole 132 first flows in the horizontal direction of the bottom side of the vegetable chamber 150 in the horizontal direction, and then flows while raising the right side of the outer side, and then changes the direction, so that the upper outside of the passage is horizontal. It is formed to flow in the direction, and thus the shape may be formed in the "c" shape of the left and right reversed.

In addition, the cold air recovery passage 134 is formed in the intermediate wall 130 in the vertical direction so as to communicate with the last portion of the cold air flow passage 160, through which the cold air flowing through the cold air flow passage 160 continuously flows It is recovered to the evaporator 140 side, of course, the cold air recovery passage 134 may be formed in the rear wall (not shown) of the refrigerator 100, not the middle wall 130.

On the other hand, with respect to the cold air inlet hole 132 to communicate the freezing chamber 110 and the vegetable chamber 150 to the vegetable chamber 150 side by opening and closing the electromagnetic damper (162) to adjust the amount of cold air flowing in Is installed, and in the vicinity of the electromagnetic damper 162, a fan (164) for forcing a flow of cold air is installed. Also, in the vicinity of the electromagnetic damper 162 to heat the incoming cold air. The heater 166 is installed, and further, a temperature sensor 168 for measuring the temperature of the vegetable chamber 150 is installed in the vegetable chamber 150.

Then, the electronic damper 162, the fan 164, the heater 166, the temperature sensor 168 is electrically connected to the electromagnetic damper 162, the fan (according to the temperature value measured by the temperature sensor 168). 164, a control unit (not shown) for overall operation control of the heater 166 to maintain the vegetable chamber 150 at an appropriate temperature is provided separately.

The operation of the independent vegetable room temperature control device of the double door refrigerator according to the present invention having the above configuration will be described below.

During operation of the double door type refrigerator 100, cold air is discharged from the evaporator 140 provided at the upper end side of the freezer compartment 110 to the inside of the freezer compartment 110, flows to the lower side, and then flows to the upper side again, and the evaporator 140 is reversed. It is recovered to the side.

Accordingly, a certain amount of cold air is always maintained in the freezing chamber 110, and some of the cold air is opened as the electronic damper 162 of the vegetable chamber 150 side is opened and the fan 164 is driven. 132 is introduced into the vegetable chamber 150 side.

Thereafter, the introduced cold air flows through the cold air flow passage 160 formed along the periphery of the vegetable chamber 150 to cool the vegetable chamber 150, and the cold air passing through the cold air flow passage 160 flows into the intermediate wall 130. It is continuously flowed through the formed cold air recovery passage 134 and then recovered to the evaporator 140 side.

Of course, the cold air recovered toward the evaporator 140 is cooled to the proper temperature again and then discharged back into the freezing chamber 110.

In the process as described above, the temperature in the vegetable chamber 150 is always measured by the temperature sensor 168 and the measured value is sent to the control unit, the control unit compares and determines whether the measured temperature value matches the appropriate temperature value, When the measured temperature value is higher than the proper temperature value, the vegetable chamber 150 needs to be cooled further. In this case, the opening amount of the electromagnetic damper 162 and the rotational force of the fan 164 are further increased.

On the contrary, when the measured temperature value is lower than the proper temperature value, the temperature of the vegetable chamber 150 should be increased. For this purpose, the controller lowers the amount of opening of the electromagnetic damper 162 and the rotational force of the fan 164, and is also required. At the time, the heater 166 for heating the cold air is driven.

Thus, according to the present invention, since the temperature of the vegetable chamber 150 can be appropriately adjusted within a wide temperature range from a low temperature corresponding to the cold air of the freezing chamber 110 to a high temperature that can be heated by the heater 166, It is possible to provide an optimized storage temperature environment according to the conditions of the food being stored.

In the foregoing description, it should be understood that those skilled in the art can make modifications and changes to the present invention without changing the gist of the present invention as merely illustrative of a preferred embodiment of the present invention.

According to the present invention, since the temperature of the vegetable compartment can be properly controlled independently within a wider temperature range, it is possible to provide an optimized storage temperature environment according to the type or amount of food stored in the vegetable compartment, thereby improving the value of the product. And more responsive to the needs of the consumer can be achieved.
