Description

Magic Room for Refrigerator

The present invention relates to a refrigerator fresh room, and more particularly, to a refrigerator fresh room capable of uniformly cooling the food stored in the fresh room and keeping the fresh room at a low temperature capable of storing meat without a thawing process.

A refrigerator is a refrigerator that supplies cold air to a storage space to keep food at a constant low temperature.

The cold air supplied to the storage space is generated through heat exchange with external air due to a phase change while a refrigerant, which is an operating fluid, circulates along a refrigeration cycle.

The refrigeration cycle includes a compressor for compressing the gaseous refrigerant, a condenser for condensing the refrigerant compressed by the compressor with liquid refrigerant, a capillary tube for reducing the liquid refrigerant passing through the condenser, and the capillary It comprises an evaporator for phase-changing the liquid refrigerant passing through the tube into gas phase refrigerant. Then, in the process of the phase change of the liquid refrigerant from the evaporator to the gas phase refrigerant to make the air around the evaporator to low temperature to generate cold air.

However, the following problems are raised in the conventional refrigerator vegetable room as described above.

First, the cold air supplied to the vegetable chamber 4 is configured to directly supply the cold air generated in the heat exchange chamber to the vegetable chamber 4. As described above, since cold air directly touches the vegetables stored in the vegetable chamber, there is a fear that the vegetables may be damaged in the water or the like.

When cold air is directly supplied to the vegetables stored in the vegetable chamber 4 as described above, the food to which the cold air touches is kept at a low temperature, but the portion where the cold air does not touch becomes relatively high and does not have uniform cooling. Is also raised.

In addition, since the cold air supplied to the vegetable chamber 4 is usually supplied through the refrigerating chamber R, the temperature of the vegetable chamber is substantially higher than the optimum storage temperature of the vegetable chamber.

In the general refrigerator, since the cold air is supplied using the temperature of the refrigerating chamber R or the freezing chamber F as a control variable, a problem arises in that the temperature of the vegetable chamber 4 cannot be set independently.

In addition, since the temperature set in the vegetable chamber maintains only a constant temperature, the kinds of foods that can be stored in the vegetable chamber are limited to, for example, vegetables and fruits. Therefore, the situation that does not satisfy the taste of consumers who want to keep a variety of food fresh.

An object of the present invention is to solve the problems of the prior art as described above, by forming a cold air passage to surround the outer surface of the fresh room, to provide a refrigerator with a fresh room that can be uniformly cooled as a whole There is.

Another object of the present invention is to provide a refrigerator having a fresh room having a cold air supply structure that can lower the temperature of the fresh room to a temperature at which meat can be stored without thawing.

It is still another object of the present invention to provide a refrigerator having a fresh room which can store various foods including vegetables by allowing the temperature of the fresh room to maintain a constant range.

However, the present invention is not limited thereto, and heat conduction may be performed to efficiently transfer cold air to the drawing chamber 10. If the degree of construction is a metal, it belongs to the technical scope of this invention.

Next will be described the operation of the refrigerator fresh room according to an embodiment of the present invention having the configuration as described above.

First, the user inputs a fresh room temperature setting key (not shown) installed in the display unit (not shown) according to the type of food to be stored in the fresh room 10.

For example, when the vegetable is to be stored in the fresh room 10, the fresh room temperature setting key (not shown) is set to 0 ° C. which is the optimum vegetable storage temperature and input. In addition, in the fresh room 10 according to the present invention, meat such as beef can be stored. If the meat is to be stored, the fresh room temperature setting key (not shown) is set to -7 ° C and input.

When the meat is stored at the temperature of −7 ° C., the meat is maintained at the same level as before the storage, so that the meat stored in the fresh room 10 is not defrosted when exposed to the outside. Since no thawing process is required, therefore, destruction or modification of nutrients in meat can be suppressed as much as possible.

In the following, an operation process when, for example, meat is to be stored in the fresh room 10 will be described based on FIG. 4. When the user inputs a predetermined temperature (for example, -7 ° C) which is a temperature suitable for meat storage from the outside (step 402), the microcomputer (not shown) reads the input predetermined freshroom set temperature.

A microcomputer (not shown) that recognizes the externally set temperature of the drawing room compares the temperature of the drawing room 10 detected by the temperature sensor 16 installed in the drawing room 10 with the externally set temperature. (Step 404).

As a result of the determination in step 404, when the temperature inside the drawing chamber 10 is higher than the set temperature input from the outside, the blower fan 12 is driven to supply cold air to the drawing chamber 10 (step 406). ).

In operation 406, when the blower fan 12 is driven, cold air of the freezing chamber F is forced into the blower fan 12 through the cold air suction port 20 and the cold air duct 30. The blowing fan 12 forcibly suctioning the cold air of the freezing chamber F through the cold air duct 30 blows the cold air into the fresh room cold air flow path C.

Since the cold air forced into the fresh chamber cold air flow path C is constituted by the heat insulating member 18 and the aluminum tray 14, the bottom face 14a, the side surface 14b, and the rear surface of the aluminum tray 14 are provided. While contacting with 14c, it is discharged to the freezing chamber F through the cold air discharge port 22 formed in one side of the barrier B. As shown in FIG.

The cold air passing through the fresh chamber cold air flow path C by the heat insulating member 18 constituting the fresh chamber cold air flow path C is transferred to the aluminum tray 14 without the cold air loss.

Since the aluminum tray 14 is made of a material having a high thermal conductivity, the aluminum tray 14 is at a low temperature, such as a cold air temperature in the fresh room cold air flow path C.

Since the drawing chamber 10 is in contact with each surface of the low temperature aluminum tray 14, the temperature of the drawing chamber 10 also drops.

That is, as described above, when the draw chamber 10 is accommodated in the aluminum tray 14, the bottom surface 10a, the side surface 10b, and the back surface 10c of the draw chamber 10 are the aluminum tray. The bottom surface 14a, the side surface 14b, and the back surface 14c of 14 are in contact with each other, and heat transfer occurs from the aluminum tray 14 to the drawing chamber 10.

As described above, the fresh chamber 10 which has received the cold air from the aluminum tray 14 starts to drop in temperature, and the microcomputer (not shown) is inside the fresh chamber 10 which the temperature sensor 16 senses. By reading the temperature, it is determined whether the temperature inside the drawing chamber 10 has reached the temperature set by the user (step 408).

As a result of the determination in step 408, when the temperature inside the drawing chamber 10 reaches the temperature input by the user, the microcomputer (not shown) turns off the driving of the blower fan 12 (step 410). The chamber 10 is kept at a predetermined temperature.

In the operation of the embodiment of the present invention, the user sets a specific temperature (for example, -7 ℃) to the holding temperature of the fresh room 10, but a predetermined range (for example, -7 ℃ ~ It is also possible to make the temperature which has 3 degreeC) into the preset temperature of the fresh room 10, of course.

That is, when the user sets and inputs the temperature setting range to -7 ° C to 3 ° C, the fresh room cold air supply mode is operated so that the fresh room 10 always maintains a temperature in the range of -7 ° C to 3 ° C.

The above embodiments of the present invention are merely one embodiment of the technical idea of the present invention, and of course, other modifications are possible within the technical idea of the present invention.

In the present invention having the configuration and operation as described above is expected the following effects.

First of all, the cold air is not supplied directly to the food stored in the fresh room, but is indirectly supplied by the cold air flow passage configured to surround the fresh room, so that the entire fresh room is cooled uniformly. .

As a result of the uniform cooling of the whole drawing room as described above, of course, the food stored in the drawing room is also cooled at the same time.

In addition, by installing a blower fan forcibly sucking the cold air of the freezer compartment and supplying the sucked cold air to the fresh chamber, the fresh chamber can be kept at a low temperature (for example, -7 ° C), so that the meat can be stored without thawing. The effect is also expected.

In addition, by installing a temperature sensor inside the drawing room, it is expected that the user can maintain the drawing room at a specific temperature desired or a temperature having a predetermined range.

In addition, by installing the blower fan and the temperature sensor as described above, it is also expected that the effect of storing a variety of food in the fresh room.
