[0002]

2. Description of the Related Art In recent years, in a refrigerator, a part of a cooling system radiating pipe has been replaced with a refrigerator opening and a partition in place of a conventional heater for the purpose of energy saving in order to prevent dew on a partition wall portion due to the temperature in the refrigerator. It has a structure to be installed on the wall.

[0003] A conventional refrigerator is disclosed in Japanese Patent Laid-Open No. 5-1980.
Is disclosed in Japanese Patent Publication No. Hereinafter, a conventional refrigerator will be described with reference to FIGS.

In FIG. 1, reference numeral 1 denotes a refrigerator body, which is formed by an upper partition wall 2 and a lower partition wall 3 to form a drawer-type freezer compartment 4 at the center, a refrigerator compartment 5 at an upper portion, and a drawer-type vegetable compartment 6 at a lower portion. Further, the freezing room 4 is a drawer type freezing room having two upper and lower stages by a central partition wall 7. Reference numeral 8 denotes a low-temperature chamber provided at the bottom of the refrigerator compartment 5, which is maintained at a partial freezing temperature of about -3 ° C. In addition, the low temperature room door 9
Having.

[0005] 10 is a compressor of a refrigeration cycle, 11 is an auxiliary condenser, 12 is a side condenser, 13 is a front condenser, and 14 is a capillary. Also one
Reference numeral 5 denotes a cooler, and the cool air cooled by the cooler 15 is blown to each of the chambers by a blower 16.

Reference numeral 17 denotes a front plate having a U-shaped cross section having bent portions formed on the upper and lower sides.
A radiating tube 18 which is a part of the second embodiment is provided. The front plate 17 is made of a material having good thermal conductivity such as an iron plate.

Reference numeral 19 denotes a heat storage material, which is attached to the back surface of the front plate 17 so as to be in contact with the radiator tube 18 so that heat can be exchanged.

Reference numeral 20 denotes an elastic holding plate which is provided with a heat insulating material 21 when the front plate is attached to the upper partition wall.
The heat storage material 19 is securely brought into close contact with the front plate 17 so that
The heat radiation of No. 8 is efficiently and reliably transmitted to the front plate 17 via the heat storage material.

The operation of the above configuration will be described below. The refrigerant compressed by the compressor 10 is supplied to the auxiliary radiator 11
After passing through the side condenser 12 to the front condenser 13, the pressure is reduced by the capillary 14 and
Evaporate at 5.

The cool air cooled by the cooler 15 is supplied to the blower 16
Then, air is blown to the freezer compartment 4, the refrigerator compartment 5, and the vegetable compartment 6, and each compartment is cooled to a predetermined temperature.

Here, the partition wall 2,
3 and 7 are cooled to easily cause dew condensation. However, during operation of the refrigeration cycle, the temperature of the radiator tube 18 becomes about 40 ° C. The temperature is kept at less than 40 ° C. to prevent the front plate 14 from dewing.

[0012]

However, in the above-mentioned conventional construction, both the upper and lower ends of the front plate extend to the inside of the refrigerator cabinet from the viewpoint of securing the strength, so that part of the heat radiation from the radiating pipe is both ends of the front plate. This causes a problem in that the heat enters the refrigerator compartment as a heat load through the section and lowers the efficiency of the refrigeration system of the refrigerator. Conversely, the temperature of the front plate is cooled by cold air in the refrigerator through both ends of the front plate, and the temperature is reduced, causing dew condensation.

[0013] The present invention solves the conventional problems and reduces the intrusion of a heat load from the front condenser into the refrigerator, thereby increasing the efficiency of the cooling system. On the contrary, the temperature of the front plate is prevented from lowering, and the dew condensation on the partition wall of the refrigerator body is eliminated.

[0014]

A front plate made of a heat conductive material attached to a front portion of a partition wall, and a non-heat conductive material such as a resin integrally attached to both ends of the front surface. It comprises a front plate reinforcing member that can be fitted to a partition wall, and a heat pipe of a refrigeration system provided on the back surface of the front plate.

[0015] Thus, the intrusion of the heat load into the refrigerator compartment is reduced, the efficiency of the cooling system is increased, and dew condensation on the partition wall of the refrigerator body is eliminated.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A front plate made of a heat conductive material attached to a front portion of a partition wall, and the partition wall made of a non-heat conductive material such as a resin attached to both ends of the front surface. A front plate reinforcing member that can be fitted, and a radiating tube of a refrigeration system provided on the back surface of the front plate, and transmitted to both ends of the radiating front plate from the radiating tube of the front condenser, but the front plate reinforcing member has a thermal conductivity. Due to the small size and the heat transfer resistance of the front plate and the front plate reinforcing member, penetration of a heat load into the refrigerator is reduced.

(Embodiment 1) A refrigerator according to an embodiment of the present invention will be described below with reference to FIGS. The same components as those in the conventional example are denoted by the same reference numerals, and description thereof will be omitted.

In FIG. 1, reference numeral 24 denotes a front plate made of a heat conductive material (iron), and a heat radiating tube 18 which is a part of the front condenser 13 is provided on the rear surface.

A front plate reinforcing member 25 made of a non-thermally conductive material such as resin and fitted to the partition wall is mounted on both ends 24 of the front plate.

Reference numeral 26 denotes a heat storage material which is attached to the back surface of the front plate 24 so as to be in contact with the radiator tube 18 so as to be able to exchange heat.

Numeral 27 denotes an elastic holding plate which is attached to the upper partition wall 2 by the heat insulating material 28 when it is attached to the front plate.
And the heat storage material 26 is securely brought into close contact with the front plate 24 so that
8 is efficiently and reliably transmitted to the front plate 17 via the heat storage material 26.

The operation of the above configuration will be described below. The heat radiation from the heat radiating pipe 18 is transmitted to the front plate 24 via the heat storage material 26. The heat diffused to both ends of the front plate 24 reduces the thermal load of the front plate reinforcing member 25 and the heat transfer resistance of the front plate and the front plate reinforcing member, thereby reducing the intrusion of a heat load into the refrigerator and improving the efficiency of the cooling system. I'll give it. Conversely, the cooling effect in the refrigerator causes the front plate 2 to pass through the front plate reinforcing member 25.
No. 4 eliminates dew condensation on the partition wall of the refrigerator without lowering the temperature.

[0023]

According to the present invention, the heat load from the front condenser into the refrigerator compartment is reduced, and the efficiency of the cooling system is improved. On the contrary, it has the effect of preventing the temperature of the front plate from lowering and eliminating the condensation on the partition wall of the refrigerator main body.
