Duct panel 110 is formed by 2 and 113, and storage room 120 is formed. A cold storage wall 116 filled with a cold storage member that stores cold heat is arranged between the side plate 102 and the side panel 112, and is supported by a support member 114.

[0003] The gap between the side plate 103 and the side panel 113,
The gaps between the top plate 101 and the top panel 111, the gaps between the side plates 102 and the cold storage walls 116, and the gaps between the cold storage walls 116 and the side panels 112 are formed by cold air passages 117 and 11 through which cool air flows.
It is eight. A refrigerator 105 is disposed on the upper surface of the top plate 101, and an exhaust port 101 a and an intake port 101 b for performing exhaust and intake of cool air are formed by a partition 115 provided on the upper panel 111. The cool air passing through the cool air passage 117 flows into the storage chamber 120 from the inlet 120a. The cool air in the storage chamber 120 flows out from the outlet 120b to the cool air passage 118.

In the refrigerator configured as described above, the refrigerator 105
Is driven, cool air is sent from the exhaust port 101a to the cool air passage 117. The cool air traveling through the cool air passages 117a and 117b contacts the cold storage wall 116 and is stored by the cold storage member in the cold storage wall 116. Then, cool air flows into the storage room 120 from the inflow port 120a to cool the inside of the storage room 120. Thereafter, the cool air flows from the outlet 120b to the cool air passage 11.

A compressor 20 is arranged at the rear of the freezer 13. A condenser (not shown) is connected to the compressor 20 via a discharge pipe 20a, and coolers 21 and 25 are connected in series via a suction pipe 20b. The condenser and the cooler 25 are connected via a first capillary tube (not shown). The second between the coolers 21 and 25
A capillary tube (not shown) is provided.

Thus, a refrigeration cycle is formed, and when the refrigeration cycle operation is performed, the coolers 21 and 25 are cooled. Defrost heaters 61 and 62 for defrosting the coolers 21 and 25 are provided below the coolers 21 and 25. 63 and 64 are drain receiving members.

Switching means is provided between the condenser and the first capillary tube, and the switching means and the cooler 21 are provided.
Are connected via a third capillary tube (not shown). By switching the switching means, only the cooler 21 can be cooled.

The cooler 21 is arranged in a cool air passage 23, and the cool air passage 23 is formed by the inner box 2b and an evaporative cover 33 made of a resin molded product. A blower 22 is disposed above the cooler 21 in the cool air passage 23. The cool air passage 23 communicates with the freezer compartment 13 through an inlet 13a and an outlet 13b to the freezer 13 provided on the back plate 33a.

The cooler 25 is provided in the cool air passage 27. The lower part of the cool air passage 27 is formed by the inner box 2 b and the back plate 34 of the vegetable compartment 12. The back plate 34 is made of a heat insulating member, and prevents the vegetable room 12 provided near the cooler 25 from being overcooled. A blower 26 is arranged above the cooler 25 in the cool air passage 27. Cold air passage 27 is outlet 1
2b communicates with the vegetable compartment 12.

The upper part of the cool air passage 27 is formed by a heat insulating member 36 fixed to the back plate 35 of the ice temperature chamber 14 and the inner box 2b. The heat insulating member 36 is provided with an opening 36a. FIG. 2 shows a front view of the refrigerating compartment 11 and the back plate 3.
5 has an opening 35a at the same position as the opening 36a. The refrigerating room 11 communicates with the cool air passage 27 through the openings 35a and 36a.

A detailed view of the blower 29 is shown in FIG.
In the cool air passage 28, air taken in from the refrigerator compartment 11 by the blower 29 through the opening 41a and cool air flowing through the cool air passage 27 by the blower 26 are mixed.

The cold air passage 28 on the back side of the refrigerator compartment 11 is formed by a member 42 forming the inner wall of the refrigerator compartment 11 and the inner box 2b. The member 42 is formed of a heat conductive member having a heat conductivity having a shape as shown in FIG. 5 (for example, an aluminum alloy or stainless steel having good workability and high rust prevention effect). This enables cold storage and release of cold heat. When the thickness of the heat conducting member is large, the cold storage capacity increases and the strength also increases. When the thickness is small, the efficiency of discharging cold heat increases, which is advantageous for weight reduction. Therefore, a thin plate or a thick plate may be selected and provided at an appropriate time in accordance with the purpose.

If the surface of the member 42 is provided with an uneven shape by press working or the like, the surface area can be increased. As a result, the amount of cold storage or the release of cold heat increases, and the cooling efficiency can be improved. Further, the strength of the member 42 can be reinforced by providing the concave or convex portions that are linearly continuous.

FIGS. 8 and 9 show detailed cross-sectional views of the upper end and the lower end of the member 42. FIG. According to these figures, the member 4

FIG. 4 is a top sectional view of the refrigerator compartment 11.
The back of the member 42 is supported by a protrusion 28a formed on the inner box 2b so as to extend vertically. Thus, the bending of the member 42 due to the pressing force from the front surface is prevented, and the cool air flowing through the cool air passage 28 is rectified to improve the noise reduction and the blowing efficiency. A deodorizing section 50 is provided in the cool air passage 28. The deodorizing section 50 is made of a deodorizing agent such as activated carbon, and may be provided with a member or a device capable of executing another deodorizing method.

In the refrigerator 1 having the above configuration, the blower 22
Is driven, the air in the freezing compartment 13 is guided to the cool air passage 23 from the outlet 13b. The air is cooled by exchanging heat with the cooler 21 and flows into the freezing compartment 13 through the inlet 13a. Thereby, the inside of the freezing room 13 is cooled.

When the blowers 26 and 29 are driven, the air in the vegetable compartment 12 is led from the outlet 12b to the cool air passage 27. The air is cooled by exchanging heat with the cooler 25 and mixed with the air in the refrigerator compartment 11 guided to the cool air passage 28 from the opening 41a. After that, it flows through the cold air passage 28 and flows into the refrigerator compartment 11 through the openings 42a and 43a. Also,
Part of the cold generated by the cool air flowing through the cool air passage 28 is discharged as cold into the refrigerator compartment 11 via the member 42. Thereby, the inside of the refrigerator compartment 11 is efficiently and uniformly cooled by the cool heat from the member 42 and the cool air from the openings 42a and 43a.

The air in the refrigerator compartment 11 is supplied between the shelves 45 and between the shelves 45.
, Flows through the cold air passage 30 from below the ice temperature chamber 14 through the opening 32 a, and flows into the front of the vegetable room 12. Furthermore, it passes from the front of the storage container 54 to the lower side, and
2 is cooled. Then, the cooler 2 from the outlet 12b
The air is guided to the lower part of 5, and cool air circulates.

The compressor 20 and the blower 26 are operated and stopped based on the detection result of the temperature sensor (not shown), and the temperatures of the refrigerator compartment 11 and the vegetable compartment 12 are maintained at, for example, 3 ° C. A part of the cool air flowing through the cool air passage 27 flows into the ice temperature chamber 14 through the openings 35a and 36a. Thereby, the inside of the ice temperature chamber 14 can be cooled to a lower temperature, and can be maintained at, for example, -1 ° C.

When the cooling in the cooler 25 is stopped and one or both of the blowers 26 and 29 are operated, the members 42
The cold air passing through the cooling passage 28 is cooled by the cold heat accumulated in the cooling air. The cold air cools the refrigerator compartment 11. When the blower 26 is operated, the cooler 25 can be further defrosted to humidify the inside of the refrigerator compartment 11.

According to the present embodiment, the member 42 functions as a heat conducting plate that conducts a part of the cold heat of the cool air passing through the cool air passage 28 and discharges the heat into the refrigerator compartment 11 from the entire surface. Therefore, the refrigerator compartment 11 is uniformly cooled by the cool heat uniformly discharged from a wide area.

Further, the member 42 may be a cold storage member in which a jelly-like or liquid cold insulator 42c is enclosed by packaging materials 42f and 42g as shown in FIG. By doing so, the member 42 is stored more cold by the cool heat of the cool air flowing through the cool air passage 28, and discharges as cool heat according to the temperature distribution in the refrigerator compartment 11. Therefore, the refrigerator compartment 11 is uniformly cooled.

Furthermore, the cool storage member absorbs heat and dissipates heat during the stop of the compressor 20 and fluctuations in the cool air temperature in the cool air passage 28, thereby maintaining the cool air temperature in the cool air passage 28. At this time, since the cold storage member forms the inner wall of the refrigerator compartment 11, the space of the refrigerator compartment 11 can be widened, and the space of the refrigerator 1 can be saved. It is more desirable that the packaging materials 42c and 42d be made of a thermally conductive aluminum alloy or stainless steel.

The cool air generated at a low temperature by the cooler 25 is slightly heated by mixing with the air in the refrigerator compartment 11. Thereby, dew condensation or icing which occurs on the member 42 can be prevented, and drying of the refrigerator compartment 11 and the vegetable compartment 12 can be prevented.

By providing a cooler 25 for cooling the refrigerator compartment 11 and the vegetable compartment 12 and a cooler 21 for cooling the freezer compartment 13, the temperature of the cool air flowing through the cool air passages 27 and 28 is reduced. It can be set higher than the cold air temperature. Thereby, dew condensation and icing that occurs on the member 42 can be further prevented, and the refrigerator compartment 11 and the vegetable compartment 12
Can be further prevented from drying.

The member 42 is erected on the back of the refrigerator compartment 11 and extends vertically. For this reason, when the temperature and humidity in the refrigerator compartment 11 are extremely increased due to the number of times of opening and closing of the heat insulating door 3, even if dew is formed on the member 42 and water droplets are generated, they do not drop directly on the storage. Therefore, without damaging the storage,
Good storage condition can be maintained.

At this time, when the blowing of the cool air in the cool air passage 28 cooled by the cooler 25 is stopped, the member 42 is moved to the refrigerator compartment 1.
1 and the cooling chamber 11
The inside dries. As a result, some of the water droplets evaporate while flowing down the member 42 and the back plate 35. Therefore, the humidity in the refrigerator compartment 11 can be increased again. Further, if a porous (for example, an oval hole, a round hole, etc.) fence-shaped protective wall is provided in front of the member 42, the member 42 can be made thinner, so that the effect of releasing cold heat is improved. It also prevents scratches and damage.
