A compressor 20 is disposed at the rear of the freezing compartment 13 via a heat insulating layer.
The refrigeration cycle is configured by being connected to the evaporators 21 and 25 disposed in the inside 7.

FIG. 3 shows a refrigeration cycle diagram. A condenser 71 is connected to the compressor 20, and refrigerant flows through the capillary tubes 72 and 73 and the evaporator 2 as indicated by an arrow A1.
A first refrigeration cycle returning to the compressor 20 through 5 is constituted. In addition, as shown by the arrow A2, the refrigerant passes through the capillary tubes 72 and 74 and the evaporator 21 and the compressor 2
A second refrigeration cycle returning to zero is configured.

The first refrigeration cycle and the second refrigeration cycle are configured in parallel, and when the on-off valve 78 is opened, the first refrigeration cycle and the second refrigeration cycle are simultaneously executed. Therefore, cooling by the evaporators 21 and 25 is performed, and the blower 2

When the temperatures in the refrigerator compartment 11 and the vegetable compartment 12 are within a predetermined range, the compressor 20 is used only for cooling the freezer compartment 13 so that the refrigerating capacity of the freezer compartment 13 can be further increased. .

Further, since the evaporators 21 and 25 are arranged in parallel, the connection of the piping through which the refrigerant flows can be simplified. That is, many of the welding locations can be provided in the machine room in which the compressor 20 is disposed, so that productivity and maintainability are improved. Reference numerals 75 and 76 denote temperature sensors for detecting the temperatures in the refrigerating compartment and the freezing compartment.

Since the pipes are connected to each other, the variation between the evaporator 25 for the refrigerator compartment 11 and the evaporator 21 for the freezer compartment 13 individually affects each capillary tube, and the adjustment of each of the capillary tubes is performed in series. Also, stable cooling characteristics can be obtained and mass productivity is high.

The lower part of the cold air passage 27 is formed by the back plate 35 of the ice temperature chamber 14 and the inner box 2b. The upper portion of the cold air passage 27 is provided with the member 42 forming the back wall of the refrigerator compartment 11 and the inner box 2 b or the partition wall 27.
a and the inner box 2b. The partition 27a separates the evaporator 25 and the pressure chamber 27b, and the blower 26 is attached to the partition 27a. The member 42 is formed by sheet metal processing a metal plate such as aluminum or stainless steel.

A ceiling cool air passage 57 communicating with the cool air passage 27 is provided at a ceiling portion of the refrigerator compartment 11.
Reference numeral 7 is formed by an upper plate 43 made of a resin molded product and the inner box 2b. The discharge port 4 is provided in the member 42 and the upper plate 43.
2a and 43a are provided. An illumination lamp (not shown) covered with a transparent illumination cover (not shown) is provided at the center of the ceiling of the refrigerator compartment 11 to illuminate the inside of the refrigerator compartment 11.

A water supply pump 66 for supplying water to the ice maker 67 is provided on the left side of the cool air passage 27, and a water supply tank (not shown) is set in front of the water supply pump 66. An ice temperature duct 60 that branches from the discharge side of the blower 26 and guides cool air to the back of the ice temperature chamber 14 is provided on the right side of the cool air passage 27. Also, behind the vegetable room 12,
An electric circuit 58 for driving and controlling the compressor 20, the blowers 23 and 26 and the like is provided via a heat insulating layer such as the heat insulating material 2c.

In the refrigerator 1 having the above configuration, the compressor 20
The cooling of the evaporator 21 is performed by driving the
2 is driven, the air in the freezing room 13 returns to the return port 13b.
From the cooling air passage 23. The air is cooled by exchanging heat with the evaporator 21 and discharged to the freezing compartment 13 through the discharge ports 13a and 13c. Thereby, the inside of the freezing room 13 is cooled to, for example, −20 ° C.

When the blower 26 is driven, the air in the vegetable compartment 12 is sucked into the cool air passage 27 from the return port 12b.
The air is cooled by exchanging heat with the evaporator 25, and is cooled by the cold air passage 2.
7 and is discharged into the refrigerator compartment 11 through the discharge ports 42a and 43a.

Since the member 42 is made of metal, a part of the cool heat of the cool air flowing through the cool air passage 27 is released into the refrigerator compartment 11 through the member 42 as cold heat. Thus, the inside of the refrigerator compartment 11 is efficiently and uniformly cooled to, for example, 3 ° C. by the cool heat discharged from the member 42 and the cool air discharged from the discharge ports 42 a and 43 a. The member 42 may be a material having high thermal conductivity, and may be a ceramic material, a resin material impregnated with a metal filler, or the like.

The cold air in the refrigerator compartment 11 is discharged to the front of the vegetable compartment 12 through the communication passage 12a between the shelves 45 and 45a and through the front surface. Then, the inside of the vegetable compartment 12 is cooled down from the front of the storage container 54, and the cool air is circulated from the return port 12b to the cool air passage 27. Discharge ports 42a, 43
The cold air discharged from a into the refrigerator compartment 11 is deprived of cold heat by the food and the like before flowing into the vegetable compartment 12. Thereby, the temperature of the cold air circulating in the refrigerator compartment 11 rises, and the raised cold air flows into the vegetable compartment 12, so that the vegetable compartment 12
The inside is cooled to, for example, 5 ° C.

Further, the cool air sent from the blower 26 is immediately discharged from the discharge port 60 a through the ice temperature duct 60 to the ice temperature chamber 1.
4 is discharged in an appropriate amount. Thereby, the temperature in the ice greenhouse 14 can be maintained at, for example, -1 ° C. The temperature of the ice greenhouse 14 is reduced to 0 ° C. by reducing the amount of cold air discharged inside.
When it is near, it becomes a chilled room, and when the amount of cold air is further reduced and the room temperature is around 5 ° C., it becomes a vegetable room. The amount of cool air can be changed by opening and closing a door pivotally supported so as to cover the discharge port 60a.

According to the present embodiment, a part of the cold heat of the cool air passing through the cool air passage 27 is transmitted by the member 42 and discharged into the refrigerator compartment 11 from the entire surface of the member 42. Therefore, the refrigerator compartment 11
Since the substantially entire width of the rear surface of the refrigerator 11 is covered by the member 42, the cool air can be uniformly discharged from the rear surface of the refrigerator 11 and the interior of the refrigerator 11 can be uniformly cooled. Since the evaporator 25 is disposed above the refrigerator compartment 11 facing the refrigerator compartment 11 in which the member 42 is arranged, and is not disposed facing the vegetable compartment 12 as in the conventional example, Path to discharge ports 42a, 43a, evaporator 25 and member 42
And the distance between them is reduced.

Accordingly, the discharge side of the blower in the cool air passage 27 is shortened, and the ventilation efficiency is improved. Also, the cold air passage 27
Since the entire length of the airbag is shortened, the ventilation efficiency is further improved.
Since the cool air can reduce the heat absorption in the middle of the passage through the cool air passage 27 and discharge the cool air to the refrigerator compartment 11 or discharge the cool heat from above, the cooling efficiency by the evaporator 25 can be improved. . In addition, the refrigerator compartment 11 can be cooled more uniformly. Further, it is not necessary to provide a thick heat insulating material on the front surface of the evaporator 25 as in the prior art,
The use efficiency of the space inside can be improved.

The same effect can be obtained by disposing one or both of the evaporator 25 and the member 42 on the ceiling surface 11a or the side wall 11b of the refrigerator compartment 11. The member 42
When the thickness is large, the cold storage capacity increases, and the strength also increases. When the thickness is small, the efficiency of discharging cold heat is improved, 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.

The member 42 may be a regenerative member in which a jelly-like or liquid refrigerating material is enclosed by a packaging material such as metal. In this way, the member 42 is stored more cold by the cool heat of the cool air flowing through the cool air passage 27 and is discharged as cool heat according to the temperature distribution in the refrigerator compartment 11. Therefore, the refrigerator compartment 11
Is uniformly cooled.

Further, 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 27, so that the cool air temperature in the cool air passage 27 can be kept constant. Then, the temperature in the refrigerator compartment 11 can be stably and uniformly maintained at a constant temperature.

The cool air flowing through the cool air passage 27 is supplied to the evaporator 2.
5, the member 42 and the evaporator 25 are spaced apart from each other. Thereby, the evaporator 2
Even if the temperature of the member 5 becomes extremely low (for example, −15 ° C.), the member 42 does not become supercooled, and dew condensation, icing, and frosting can be prevented. As a result, it is possible to obtain a refrigerator that is suitable for storing storage products (vegetables and raw foods) that are prevented from drying in the cold air and are easy to dry.

Also, by separating the member 42 and the evaporator 25, the evaporator 25 is fixed to the inner box 2b, and then the evaporator 25 is connected to the compressor 20 by piping, and then the member 42 is installed. Good. Therefore, assembling becomes easier than installing the member 42 integrated with the evaporator 25 as in the related art. Since the width of the member 42 is larger than the width of the evaporator 25 and the width of the partition 27a, the welded portion and the partition 2
7a and the like can be covered by the member 42, and there is no need to separately provide a member for hiding. In addition, since the cold heat from the evaporator 25 can be widely and indirectly discharged into the refrigerator compartment 11, a refrigerator having a uniform cooling efficiency and free from icing or dew condensation can be obtained.

When the width of the cool air passage 27 is increased, the cross-sectional area of the cool air passage 27 increases, and the flow speed of the cool air decreases. In the present embodiment, the width of the cold air passage 27 is
Is larger than 1/2 of the width of the evaporator 25, and the width of the evaporator 25 is further increased. For this reason, even if the blowers having the same air volume are used, the circulation speed of the cool air is reduced and the ventilation resistance is reduced. As a result, the heat exchange efficiency between the evaporator 25 and the cool air and the air blowing efficiency of the blower 26 can be improved. Therefore, the cooling efficiency of the evaporator 25 can be improved.
Further, the power consumption of the blower 26 can be reduced, and the noise due to the blower can be reduced.

Further, from the back surface of the refrigerator compartment 11, cold heat is released by the member 42 and cool air is discharged through the discharge port 42a, and from the front of the refrigerator compartment 11 through the ceiling cool air passage 57 and the discharge port 43a. The cool air is discharged through the refrigeration chamber, so that the entire refrigerator compartment 11 can be uniformly cooled. In addition, since the blower 26 is located above the evaporator 25, the ceiling cool air passage 5
7, the cool air can be efficiently sent to the discharge port 43 a disposed in the back of the cool air passage 57 (front side of the refrigerator compartment).

If the outlets 43a are provided in many parts of the entire surface of the upper plate 43 and small openings through which cool air passes vertically are provided on the shelves 45, 45a, the refrigerator compartment 11 can be cooled evenly. Is done. If the discharge port 42a is not provided in the member 42 and the discharge port 43a of the upper surface plate 43 is formed in front of the refrigerator compartment 11, the discharged cool air flows down the front of the refrigerator compartment 11 and the open / close door 3 is opened. As a result, it becomes an air curtain to suppress the entry of outside air, thereby suppressing a rise in the temperature inside the refrigerator.

The return port 12b is connected to the discharge ports 42a, 43
Since it is arranged at a position distant from “a”, it is possible to prevent a short circuit in which the discharged cool air flows into the return port 12b without circulating in the refrigerator compartment 11, thereby improving the cooling efficiency. In addition, the entire surface of the member 42 can be used as cold heat release, thereby enabling uniform cooling of the room, and can be used as a reflector for illuminating light for illuminating the refrigerated room from above, thereby uniformly illuminating the room. be able to.

Further, by installing the electric circuit 58 behind the vegetable compartment 12 in which the temperature in the refrigerator is higher than that of the refrigerator compartment 11 and the freezer compartment 13, the thickness of the heat insulating material 2c can be reduced. Space utilization efficiency can be further improved.

The cool air passage 27 leading to the evaporator 25
Is located above and below the storage box 58a and the electrical cover 58b of the circuit storage section for storing the electric circuit 58 through the inner box 2b and the heat insulating material 2c, which are heat insulating layers, and has a cold air passage in the front-rear direction. 27 and the circuit storage section do not overlap, which also improves the utilization efficiency of the space in the vegetable compartment 12.

Further, the return port 12 is located below the cool air passage 27.
b, the return port 12b is located above the back of the vegetable compartment 12, so that the cool air flows sufficiently to the vicinity of the upper rear portion of the vegetable compartment, and the vegetable compartment 12 can be cooled more efficiently. It has become.

A vegetable case cover 54 a is provided above the storage container 54 so as to cover the upper opening of the storage container 54. The space formed by the vegetable case cover 54a and the partition plates 31 and 32 also
a refrigerator compartment 11 discharged to the front inside the vegetable compartment 12 through
A part of the cool air in the inside becomes a cool air passage that flows backward, and a convex portion is provided from at least one of the vegetable case cover 54a and the partition plates 31 and 32, and the opening area of the cool air passage is adjusted to thereby provide a vegetable case cover. The amount of cool air flowing rearward on the top of the storage container 54 and the amount of cool air flowing forward of the storage container 54 can be appropriately set, so that the stored items in the storage container 54 can be efficiently indirectly cooled to an appropriate temperature.

The inner box 2b located above the storage box 58a near the return port 12b has an inclined surface that becomes higher toward the rear, and the return cool air sucked into the return port 12b changes its flow direction. Instead, as in the case of the vertical surface of the inner box 2b, it is easy to flow upward in the cold air passage 27. Therefore, the ventilation resistance is reduced, which helps to improve the ventilation efficiency, and also prevents the generation of eddy currents, which also helps to reduce the ventilation noise.

Further, when the upper part of the storage box 58a is substantially horizontal, the heat insulating material 2c filled between the upper part of the storage box 58a and the inclined surface of the inner box 2b is vertically displaced from the return port 12b. Can be made thicker in front of the upper portion of the storage box 58a, which is a substantially horizontal surface, without sufficiently reducing the opening area of the storage box 58a, and the heat generated from the electric circuit 58 is sufficiently insulated. The cooling efficiency is improved by preventing intrusion into the air.

The storage box 5 having a substantially horizontal surface
8a, from the front to the back of the upper part of the upper part of the heat insulating material 2c.
Increases in thickness, thereby further preventing heat and the like from the electric circuit 58 from entering the inside of the storage, thereby helping to further improve the cooling efficiency.

Further, the upper part of the storage box 58a has a slope which becomes higher toward the rear like the slope of the inner box 2b.
If the heat insulating layer composed of the inclined surface of the inner box 2b and the heat insulating material 2c around the inner box 2b and the upper portion of the storage box 58a having the inclined surface is formed as the inclined surface having a required thickness, the storage box 58a is maintained without impairing the heat insulating efficiency. The capacity of the circuit storage section composed of the above can be increased, the storage of the electric circuit 58 can be facilitated, and the circuit storage section can be reduced by appropriately adjusting the size of the electric circuit 58, and the storage of the inner box 2b around the circuit storage section can be reduced. The amount of inward protrusion is reduced, which also increases the space utilization efficiency without compromising the heat insulation efficiency.

It should be noted that, even if the inclined surface of the inner box 2b located above the storage box 58a and the inclined surface of the upper portion of the storage box 58a are part of the corresponding portions, the above-mentioned effects can be obtained to some extent. In addition, at least a part of the inclined surface may be a curved surface, and the inclined surface of the inner box 2b and a substantially vertical surface of the inner box 2b in the vicinity thereof may be smoothly formed by a part of the curved surface that is concave upward. In the case of vacuum forming in the manufacture of the inner box 2b, tearing at the edge of the inner box 2b is less likely to occur, and the direction of the cool air flow gradually changes, so that the cool air flows more easily.

The storage box 58 near the blower 22
a The inner box 2b located below has an inclined surface that becomes lower toward the rear, and the cool air near the inner box 2b around the rear of the blower 22 sucked by the fan of the blower 22 gradually changes its direction. The air flows easily in the direction of the fan of the blower 22 on the inclined surface of the inner box 2b, which helps to improve the blowing efficiency and also prevents the generation of the vortex, thus helping to reduce the blowing noise.

When the lower part of the storage box 58a is substantially horizontal, the heat insulating material 2c filled between the lower part of the storage box 58a and the inclined surface of the inner box 2b maintains the air blowing performance. Can be thicker in front of the lower part of the storage box 58a, which is substantially horizontal,
The heat generated from the electric circuit 58 is sufficiently insulated, and the heat generated from the electric circuit 58 is prevented from entering the inside of the storage, thereby improving the cooling efficiency.

The storage box 5 having a substantially horizontal surface is used.
8a, from the front to the back of the lower part,
Increases in thickness, thereby further preventing heat and the like from the electric circuit 58 from entering the inside of the storage, thereby helping to further improve the cooling efficiency.

Further, the lower portion of the storage box 58a has a slope which becomes lower toward the rear similarly to the slope of the inner box 2b.
When the heat insulating layer composed of the inclined surface of the inner box 2b, the heat insulating material 2c around the inner box 2b, and the inclined lower portion of the storage box 58a is formed to have the required thickness, the storage box 58a and the like can be moved without impairing the heat insulation efficiency. The capacity of the circuit storage section can be increased, and the storage of the electric circuit 58 can be easily performed.
By appropriately adjusting to the size of 8, the circuit housing portion can be made smaller, the amount of the inner box 2b around it protruding into the inside of the box is reduced, and this also reduces the space use efficiency without impairing the heat insulation efficiency. Will be improved.

It should be noted that, even if the inclined surface of the inner box 2b located below the storage box 58a or the inclined surface of the lower portion of the storage box 58a is a part of the corresponding portion, the above-mentioned effect can be obtained to some extent. In addition, at least a part of the inclined surface may be a curved surface, and the inclined surface of the inner box 2b and a substantially vertical surface of the inner box 2b in the vicinity thereof may be smoothed by a part of the curved surface convex upward. In the case of vacuum forming in the manufacture of the inner box 2b, tearing at the edge of the inner box 2b is less likely to occur, and cool air is more likely to flow.

Further, a space including a machine room provided with the compressor 20 and the like below the freezing room 13 provided through the freezing room 13 and a heat insulating layer is partitioned into right and left by a partition wall extending forward and backward. Near the compressor 20 behind the partition wall, a blower 77 for the condenser is provided.
, A compressor 20 is provided on the right side, and at least a part of the condenser 71 is provided on the left side.
7, the outside air is sucked in, and at least a part of the condenser 71 provided on the left side is cooled, and the condenser blower 7 is cooled.
After the air passing through 7 cools the surface of compressor 20 and a passage is provided in the space so as to be discharged into the room from the right front, at least part of condenser 71 and the compressor 71 are compressed by condenser blower 77. The machine 20 and other heating elements in the machine room and the space can be cooled.

Then, a portion of the machine room cover 20c for closing the machine room in which the compressor 20 and the like are provided, which is on the left side of the partition wall and has a pressure lower than the atmospheric pressure when the condenser blower 77 is operated. Is provided with an opening 20d,
An opening 20d is provided on the low-pressure side of the passage, so that air is sucked from the outside of the back of the refrigerator 1 through the opening 20d, and serves to cool parts of a machine room including the compressor 20 and the like. .

Furthermore, unlike the conventional case, the hot air that has cooled the heat-generating components in the machine room such as the compressor 20 is not discharged to the outside of the back of the refrigerator 1 but is sucked even in the air outside of the back of the refrigerator 1. There is no rise in the temperature of the outside air near the back of the refrigerator 1 due to the discharge of hot air, and the storage box 58a and the electrical cover 58b that store the electric circuit 58 are:
Since it is located at a lower position than the conventional product, the rise of the outside air temperature around it is small, and as a result, the temperature rise of the electric circuit 58 is also suppressed lower than before, and the electric circuit 58
The electric parts and circuit boards of which the allowable limit temperature is low can be used, and when the conventional parts are used, the margin of the temperature limit increases, which leads to the improvement of the quality.

Further, in the passage on the side where the compressor 20 is located,
If the condenser blower 77 is provided by adding a partition in the front-rear direction in front of the compressor 20 and an opening similar to the opening 20d is provided in the machine room cover 20c near the rear of the compressor 20, the refrigerator 1 near the compressor 20 , The backside of the refrigerator 1 of the compressor 20 can be further cooled, the temperature rise of the compressor 20 in the vicinity of the machine room cover 20c by the compressor 20 can be further reduced, and the electric circuit 58 can be accommodated. The rise of the outside air temperature around the storage box 58a and the electrical equipment cover 58b is further reduced.

In order to keep the radiation of the radiant heat of the compressor 20 to the outside low, as shown in FIG.
Is preferably covered with a wall surface extending from the upper part of the opening 20d, and is opened downward. This also serves to reinforce the periphery of the opening 20d and also to prevent water from entering the machine room.

The low pressure section such as the opening 20d and the machine room is connected to the opening of the storage box 58a serving as the circuit housing and the electrical cover 58b by a communication path, and the inside of the circuit housing is connected to the low pressure section such as the machine room. If the circuit housing is separately provided with an opening communicating with the outside air so as to be connected by the communication path, the air in the circuit housing flows into the low-pressure section of the machine room, forcing the electric circuit 58 in the circuit housing. Cooling can be performed, and electric components and circuit boards of the electric circuit 58 can be used with lower allowable limit temperature. When using conventional parts, the margin of temperature limit is increased, which leads to further improvement in quality. Will be.

Even if the amount of heat generated by the components of the electric circuit 58 in the circuit housing for controlling the rotation speed of the compressor 20 or the like by frequency conversion or the like is increased and cooling is required, the circuit housing and the circuit housing may be cooled. Since the machine room with the compressor 20 and the blower 77 for the condenser is close to each other and can be connected to each other by a short communication passage, the ventilation resistance of the communication passage is small, and the ventilation area may be small, and it is possible to use the conventional device. Even a small and compact condenser blower 77 is sufficiently useful.

Further, an opening communicating with the outside is provided at a position below the circuit housing portion on the rear side of the refrigerator 1, and a portion of the communication path connected to the machine room side opening is connected to the opening, and the inside of the circuit housing portion is connected. If an opening for communicating with the outside air is separately provided above the circuit storage portion so as to connect the external space on the back side of the refrigerator 1 to the outside, ventilation by natural convection becomes possible, and the electric circuit 58 in the circuit storage portion is cooled. With
When the communication path is connected to the inside of the circuit storage section, if the lower surface side of the circuit storage section is connected to the communication path, the communication path becomes drainable.

The communication path may be formed by providing a duct on the back surface of the refrigerator 1, and may be provided in the heat insulating material 2c as long as the inside of the refrigerator has a sufficient heat insulation thickness. .

A storage box 58a, which is a circuit storage section, and an electrical cover 58b are provided on the rear side of the refrigerator 1 near the upper side of the blower 22 below the refrigerator 1 via a heat insulating layer including a heat insulating material 2c. Is provided with an electric circuit 58, and is electrically connected to each electric component including the compressor 20 by wiring (for example: lead wire).
Opening / closing valve (reference numeral 78 shown in FIG. 3), defrosting heater 62 on freezer compartment 13 side, blower 22, condenser blower 77, temperature sensor for freezer compartment 13 (reference numeral 76 shown in FIG. 3), ice maker 6
The wiring between the electrical components such as 7 and the electric circuit 58 is much shorter than the conventional product.

Therefore, the cost of the wiring material is reduced, and the work of assembling the wiring and the bundle of the wirings into the refrigerator becomes easy, so that the assemblability and the reliability of the finish are improved. Also, after temporarily fixing a wire or a bundle of wires to the heat insulating material 2c side of the inner box 2b with a tape or the like, a gap between the inner box 2b and the outer box 2a is filled with a heat insulating material 2c such as urethane foam. Since the number of locations occupied by the wiring material is small, the possibility of occurrence of locations that hinder flow of urethane or the like due to the wiring material is reduced, and the possibility of generation of voids (gas spaces) in the heat insulating material 2c is also reduced. As a result, the area of the heat insulating material 2c occupied by the wiring member having a high thermal conductivity is reduced, which contributes to the improvement of the heat insulating property, thereby saving energy.

In FIG. 1, the water supply pump 66, the defrost heater 61 and the blower 26 on the side of the refrigerator compartment 11,
The length of the wiring to the electric circuit 58 to the temperature sensor (reference numeral 75 shown in FIG. 3) and the like does not vary much from the conventional product, but the wiring direction is different from that of the conventional product.
In this case, the thickness of the bundled wires is smaller than that of the conventional product, and the workability in assembling such as routing of the bundle of wires and temporary fixing with tape or the like is improved.

Although the wiring to the illumination lamp 51 is long, the number of wirings is small (for example, four), so that the possibility of deterioration in heat insulation and workability is very small. In addition, the defrost heater 61, the evaporator 25, and the blower 26 are lowered below,
If the storage box 58a and the electrical cover 58b are provided near the upper part of the circuit storage section, the length of the wiring to the electric circuit 58 is further shortened, and the effects of the above are further improved.

Further, wiring outlets are provided below the lower wall surface or the side wall surface of the circuit box of the storage box 58a and the electrical cover 58b, and when each of the wirings is pulled out, the downward wiring occupying most of the wiring. The length can be further shortened, and the above effect is further improved. In addition, when the wiring outlet is provided on the lower wall surface of the circuit housing part, even if dew condensation occurs around the wiring due to the thickness of the heat insulation layer, moisture due to the dew condensation hardly rises upward. In addition, it is possible to prevent moisture from entering the circuit housing.

Further, when different wiring outlets are provided above the upper wall surface or the side wall surface of the circuit housing portion, and the wiring upward is drawn, the number of wiring outlets increases, and the circuit housing of the heat insulating material 2c is stored. Although the number of sealing processes for preventing intrusion into the inside increases, the length of the wiring member going upward is further shortened, and the above-mentioned effect is further improved. The circuit housing section includes the housing box 58a and the electrical cover 58b. If a similar structure (for example, a frame, a bottom, and a lid) is sufficient in strength, The same effect can be obtained.

Further, if the power cord outlet is provided vertically above the circuit housing part and from the center in the vertical direction, the distance between the power cord outlet and the outlet (the outlet of the external power source) in the vertical direction is equal to the outlet. The value is the same regardless of whether it is above or below the wall of the room, and the length of the power supply cord (not shown) of the refrigerator 1 (For example: about 50 cm), which is advantageous in terms of cost, improves assemblability, and reduces the useless slack of the cord even when it is connected to an outlet located above, particularly from a positional relationship. ,
The possibility of damage to the cord is also reduced.

Although the refrigerator compartment 11 and the vegetable compartment 12 are cooled by the same evaporator 25, even when the refrigerator compartment and the freezer compartment are cooled by the same cooler, the member 42 is cooled.
By arranging the cooler on the side where is disposed, the path until the cool air is discharged is shortened, and the same effect as described above can be obtained. Further, although the evaporators are used as the evaporators 21 and 25, the same effects as described above can be obtained by using a cooler based on the Peltier method or another cooling method.

When the member 42 is provided with a moisturizing function by providing irregularities on at least a part of the member 42 or forming the surface of the member 42 on a rough surface, dew condensation generated on the member 42 flows down. You can let it stay without you. And since indoor humidity is maintained and evaporation can be performed by evaporation of dew condensation water, it is useful for long-term preservation of stored items (especially vegetables and raw materials). Further, a moisturizer having a moisturizing function may be attached to the member 42.

In the above configuration, the evaporator 25 is provided above the rear side of the refrigeration compartment 11, but the refrigeration compartment is located closer to the partition plate 46, which is the boundary between the refrigeration compartment 11 and the ice compartment 14, which is the isolation compartment. Even when at least a part of the evaporator 25 is provided on the eleventh side, the depth of the ice greenhouse 14 is slightly shortened, but the same effect as described above is produced. In addition, if the member 42 is provided near the evaporator 25 on the ice temperature chamber 14 side, the refrigerator in which the ice temperature chamber 14 is cooled more uniformly is obtained.

In the case where at least a part of the evaporator 25 is provided on the refrigerator compartment 11 side with respect to the partition plate 32 which is the boundary between the refrigerator compartment 11 and the vegetable compartment 12, the portion on the vegetable compartment 12 side is evaporated. Although a heat insulating layer having a sufficient thickness is required in front of the vessel 25, the heat insulating layer is reduced in size as compared with the related art, so that the space can be effectively used. Further, the passage on the discharge side of the blower 26 becomes shorter than before, and a refrigerator with improved blowing efficiency can be obtained.

Further, regarding the wiring and the power cord, even if the arrangement order and the positional relationship of the storage compartments such as the refrigerator compartment 11, the vegetable compartment 12, the freezing compartment 13 and the like are different, the same effects as described above can be obtained. Furthermore, even when the refrigerator compartment 11 and the freezer compartment 13 are cooled only by the same cooler 22, the same effect as described above can be obtained.

Incidentally, that a part of the cold heat due to the cool air passing through the cool air passage is released into the storage chamber through the member means that a part of the cool air passing through the cool air passage absorbs heat from the member and cools the member.
This means that the member absorbs heat from the storage chamber and cools the storage chamber.

The storage box 58a, the electrical cover 5
A handle 80 is provided near the lower part of the circuit housing portion 8b. The handle 80 is attached to two positions on the left and right sides of the center of the back plate 2e constituting a part of the outer box 2a.

When the refrigerator 1 is lifted with the handle 80 in an upright position, the crotch is opened, the knees are slightly bent, and the arms are lowered while the back is stretched vertically. The handle 80 is located at a height where a finger can be hung in an extended posture. Therefore, a person who lifts the refrigerator 1 is placed in front of the refrigerator 1, and the person behind the refrigerator 1 holds the handle 80 and stretches his knees to stand up with his back straightened.
Can be easily lifted.

Therefore, the refrigerator 1 located below the waist
When the refrigerator 1 is lifted up with the handle 80, the handle 80 is placed at a height where a comfortable posture can be easily applied without exerting too much burden on the waist, arms and back muscles. With a large refrigerator that has a very low handle and a heavy weight like the conventional one, with the waist completely dropped (with the butt and heel attached), it is difficult to apply power and it is very difficult to lift it. With the back bent and the back bent forward, there is no danger of squatting the legs and lifting in an uncomfortable position, and injuring the lower back and back muscles.

In the refrigerator shown in the figure, a compressor 20 is provided below the refrigerator, and the compressor 20 is placed on one side in the left-right direction.
The evaporator 21 is provided on the other side on the other side different from the compressor 20 in the left-right direction via a heat insulating layer, a blower 22 is provided around the evaporator 21, and a heat insulating material provided with a required thickness (for example, 30 mm or more) 2c through the heat insulating layer having
The storage box 58a of a part of the circuit storage part is provided above the storage box.

A freezer compartment 13 is provided in front of the compressor 20, the evaporator 21, and the blower 22. The freezer compartment 13 is provided independently of the other storage compartments. Since the size of the cooler is not so large and can be set to be appropriately short in the height direction, the position where the finger of the handle 80 provided near the lower part of the circuit housing portion is unnecessarily high. Not moderate height, floor 79
Is approximately 560 mm above.

Therefore, when a sill or a narrow staircase with a little step is to be moved by two people back and forth while standing the refrigerator, the handle 80 as described above does not take an unreasonable posture. The refrigerator 1 can exert sufficient lifting power, does not hurt the waist and back muscles, can raise the refrigerator 1 sufficiently high, and can easily move the refrigerator 1. Preferably, if the height from the floor is in the range of about 500 mm to about 650 mm, the same effect as described above can be obtained.

Then, the storage box 5 near the blower 22
The inner box 2b located below 8a has an inclined surface that becomes lower toward the rear, and an arc or arc having a center is located at a position inside the refrigerator between the inclined surface and a substantially vertical surface of the inner box 2b. Since the curved surface (a part of the curved surface that is convex upward) that is a combination of straight lines smoothly connects the inclined surface of the inner box 2b, even if the handle 80 is provided near the lower part of the circuit housing, The thickness of the heat insulating material 2c sandwiched between the handle 80 and the inner box 2b is the same size and shape, and can be maintained at a thickness sufficient to maintain heat insulation.

Since the arrangement of the compressor 20, the evaporator 21, the blower 22, and the like is configured as described above, even if the handle 80 is provided at the required predetermined position, the space can be obtained without affecting the internal structure. Thus, a refrigerator can be obtained in which the heat insulation efficiency and the cooling efficiency are not reduced.

The distance between the two handles 80 in the left-right direction is the distance between the centers of the handles 80 in the left-right direction, and is set to about 220 mm to about 500 mm.
The value is almost the same as the shoulder width from the chest, and you can lift it without difficulty. The distance of the handle 80 is about 260
mm.

Further, even if the evaporator 21 is also used to cool the other part of the storage room, the size of the cooler is slightly increased, and the position of the handle is slightly increased. Even if the evaporator 21 is arranged above the compressor 20 via the heat insulating layer, the position of the handle is slightly raised, but the same effect as described above can be obtained.

Further, the handle 80 is attached to a strong part around the storage box 58a, so that the handle 80 can be attached to the refrigerator 1 more securely and reliably. When the back plate 2e and the side surface of the cabinet 2d are integrated, the back plate 2e
With respect to the strength of the above, it is more durable.

Further, if the handle 80 is formed integrally with the storage box 58a, not only the cost, the assembling work, and the quality in terms of dimensional variation can be improved, but also the refrigerator can be improved. For even more robustness to 1,
The handle 80 will be attached. If the strength of attachment between the storage box 58a and the electrical cover 58b is sufficient, the same effect as described above can be obtained even if the electrical cover 58b and the handle 80 are integrally formed.

In FIG. 2, a compressor 20 is provided on the right side in the machine room below the back of the refrigerator 1, and an evaporator 21 is provided on the left side, which is different from the compressor 20 in the left-right direction, via a heat insulating layer.
And a blower 22 around the evaporator 21.
The evaporator 25 is provided in the refrigerating room 11 above the blower 22 via a heat insulating layer, and a blower 26 is provided around the evaporator 25.

As shown in FIG. 3, a condenser 71 is connected to the discharge side of the compressor 20, and the evaporator 21 and the evaporator are connected in parallel to the discharge side of the condenser 71 and the suction side of the compressor 20. Reference numeral 25 is a refrigeration cycle including connected capillary tubes 73 and 74 provided corresponding to the evaporators 21 and 25, and a refrigerant flow path.

Further, as shown in FIG. 2, the suction pipe 21a is connected to the evaporator 21 for the freezer compartment 13 from the left side, and the suction pipe 25a is connected to the evaporator 25 for the refrigerator compartment 11 from the right side. The suction pipes 21a and 25a are distributed to the evaporator 2
1, 25 are connected.

Then, the suction pipe 25a is connected to the inner box 2
b, enters the side where the heat insulating material 2c is located, is guided downward near the rear side wall of the refrigerator 1, and as it is, near the rear side wall on the right side different from the side where the evaporator 21 is located. As a result, it is drawn into a machine room near the compressor 20. In addition, around the opening of the inner box 2b and the suction pipe 25a of the part drawn out to the machine room,
Sealing treatment is applied to each of the outer box 2a and the inner box 2
This prevents leakage of the heat insulating material 2c such as urethane foam filled in the gap between the heat insulating material 2c and b.

Further, the suction pipe 21a is connected to the inner box 2b.
Through the opening of the refrigerator 2, enter the side where the heat insulating material 2 c is located, rise once near the rear side wall of the refrigerator 1, and then are guided again downward, and the partition plate 19 between the vegetable compartment 12 and the freezer compartment 13
Like the suction pipe 25a, the evaporator 21 is routed to the right side in the rear heat insulating material 2c, passes through the vicinity of the rear side wall on the right side different from the side where the evaporator 21 is located, and is drawn out to the machine room near the compressor 20. . The suction pipes 21a and 25a are connected to a common suction pipe in the machine room and then connected to the suction side of the compressor 20.

Note that the opening of the inner box 2b and the portion drawn into the machine chamber around the suction pipe 21a are also subjected to a sealing treatment, respectively, so that the outer box 2a and the inner box 2b are also sealed. To prevent leakage of the heat insulating material 2c such as urethane foam filled in the gap between the heat insulating material 2c.

A capillary tube 74 is provided on the surface of the suction pipe 21a, and a capillary tube 73 is provided on the surface of the suction pipe 25a.
Each is soldered and attached. Each of the capillary tubes 73 and 74 is connected to each component as shown in FIG. 3 to constitute a refrigeration cycle.

Then, the suction pipes 21a, 25a
Are connected to the evaporators 21 and 25 from the right side or the left side, and are connected to the respective suction pipes 21a and 25a.
Passes near the side wall on the back wall side different from that of the evaporator 21 for the freezing room, so that the suction pipes 21a and 25a do not pass near the evaporator 21 for the freezing room.
1 can be positioned more on one side, the width of the evaporator can be made larger, the height of the evaporator in the vertical direction can be reduced without changing the thickness of the heat insulating layer. And the storage space can be made extra large so that the volume efficiency of the storage room is increased.

Further, the cryogenic region by the evaporator 21 for the freezing room is provided only on the freezing room 13 side, including the necessary heat insulating layer thickness, and is relatively higher in temperature than the freezing room 13 above the freezing room 13. Vegetable room 13 can be taken widely
Volumetric efficiency is increased. The same effect can be obtained even if the vegetable room 12 is a different storage room (for example, a refrigerator room, a chilled room, an ice temperature room, a temperature switching room, etc.).

The suction pipe 21a to the evaporator 21 located below passes through the opening of the inner box 2b, enters the side where the heat insulating material 2c is located, and once rises up near the rear side wall of the refrigerator 1 and thereafter. , Again led down to the vegetable compartment 12
Since the inside of the heat insulating material 2c behind the partition plate 19 is routed to the right between the room and the freezing compartment 13, the suction pipe 21a can be made long. Further, the length of the capillary tube 74 soldered to the surface of the suction pipe 21a can be increased, and the amount of heat exchange between the refrigerant in the capillary tube 74 and the refrigerant in the suction pipe 21a can be increased. A refrigerator with improved efficiency is obtained.

Further, each of the suction pipes 21
Since a and 25a are drawn out to the machine room near the compressor 20, the piping work and welding work of the suction pipe (not shown) and the capillary tubes 73 and 74 in the machine room are facilitated, and the workability is improved, and the piping processing is improved. So that the finished condition is good.

The suction pipes 21a, 25a
Are connected to the evaporators 21 and 25 from the right side or the left side, respectively, and if they are guided to the vicinity of the machine room in a state where they are distributed to the left and right, the respective suction pipes are distributed to the left and right separately. As a result, the suction pipe is not biased to one side, and the thickness of the heat insulating layer can be reduced to the minimum necessary efficiency. Moreover, when each suction pipe is located near the corner on the back wall side of the inner box 2b, the thickness of the heat insulating layer such as the side wall and the back wall of the refrigerator 1 can be set to be substantially the same as that in the normal state. However, the space inside the refrigerator can be wider than that of collecting them on one side, and the volume ratio can be further improved.

Further, when the compressor and the evaporator are arranged on the left and right, the compressor and the evaporator are arranged on the left and right in a well-balanced manner. The internal volume ratio will be further improved.

Note that the above description indicates that if there are two or more evaporators, the suction pipes are almost equally distributed from the right or left side (when the number of evaporators is even, the suction pipe is divided into two equal parts, and when the number of evaporators is odd, the piping process is simplified). Therefore, the same effect as described above can be obtained by connecting to the evaporator in the same manner as described above. Moreover, even if the compressor 20, the evaporators 21, 25, the suction pipes 21a, 25a, and the like are in a reversed positional relationship in the left-right direction, it is apparent that the same effect as described above can be obtained.

In FIG. 4, the shelf 45a comprises a rotatable support shelf 45b and a movable shelf 45c which can be moved in and out. The support shelf 45b has opposed substantially U-shaped and inverted substantially U-shaped grooves 45d, 45d having open portions toward the center on both sides, and support portions 45e, 45e on both sides.
The movable shelf 45c is held on both sides by the groove 45d so as to be able to be moved in and out, and the support shelf 45b is rotatable by the support portion 45e.

A shelf support 2f is provided on the surface of the inner box 2b serving as the side wall of the refrigerator compartment 11 so as to protrude toward the inside of the refrigerator. The support portion 45e of the support shelf 45b is rotatably supported by a part of the shelf support 2f. I have. The support shelf 45b is located above the shelf support 2f.
The lower part of the groove 45d is supported, and the support shelf 45b is rotatably attached to a predetermined position on the side wall of the refrigerator compartment 11.

Further, a shelf support 2g protruding inside the refrigerator is provided at a different position of the side wall of the refrigerator compartment 11 of the inner box 2b, and a front portion of the support shelf 45b is supported. And
The moving shelf 45c pulled out forward has the shelf support 2 at the front.
The lower projection 45f, which is supported by a part of the moving shelf 45c and is located below and forward of the movable shelf 45c, is engaged with the front engaging portion of the shelf support 2g in the front-rear direction. It does not move easily.

The lower part of the mountain-shaped projection 45g at the lower front of the supporting shelf 45b is also supported by the upper rear part of the shelf support 2g, and is provided at a position inside the mountain-shaped projection 45g. The rear of the movable shelf 45c is supported on the upper part, and the movable shelf 45c is attached to a predetermined position on the side wall of the refrigerator compartment 11 together with the support shelf 45b.

Then, the vicinity of the front end of the movable shelf 45c is lifted, and the lower projection 45f is detached from the engaging portion at the front of the shelf support 2g and pushed rearward. It moves along the 45g surface, descends obliquely downward and backward, and moves backward in the groove 45d of the support shelf 45b. At this time, the backward movement of the movable shelf 45c is promoted by the function of the weight of the movable shelf 45c. Similarly, the lower protrusion 45f in front of the movable shelf 45c is also provided on the shelf support 2f.
(g) It moves along the front upper inclined surface (indicated by a dotted line) and diagonally lowers downward and rearward.
It serves to assist the backward movement of c.

Further, when the front end of the movable shelf 45c is pushed backward, the movable shelf 45c enters the lower part of the support shelf 45b.

An anchor 45k is provided below the moving shelf 45c. The anchor 45k is mounted on the movable shelf 45c at a position further inside than the lower inner end of the substantially U-shaped and inverted substantially U-shaped grooves 45d provided on both sides of the support shelf 45b. It is provided so as to protrude outward from a wall surface extending downward from the lower surface of the mounting portion.

Then, the moving shelf 45c pulled out forward
Anchor 45k is located below and forward of the shelf support 2g when the movable shelf 45c is on the shelf support 2g, and serves to prevent the movable shelf 45c from moving upward, and the shelf support 2g in front of the anchor 45k. , And a moving shelf 4
5c is prevented from protruding further forward than a predetermined position.

When the movable shelf 45c is pushed into the support shelf 45b (the state of the movable shelf 45c indicated by a dotted line), a tall storage space is provided in front of the shelf 45a on the partition plate 46 (shown in FIG. 1). Goods (for example: wine bottles) can be placed, and relatively short stocks (for example: canned beers) can be placed on the shelf 45a.

Further, after the moving shelf 45c is pushed into the supporting shelf 45b, the front of the shelf 45a is pulled up, and the supporting shelf 45b is rotated by the supporting portion 45e.
1 (the state of the shelf 45a indicated by the dotted line), many areas on the partition plate 46 (shown in FIG. 1) have tall stocks (for example: wine bottles, curries). Pots, watermelons, etc.). Then, at the time of the rotation, the anchor 45k is connected to each of the shelf supports 2k.
f, it passes through the cut of 2g upward.

The shelf 45a indicated by the dotted line complicates the drawing, so that the moving shelf 45c pushed into the support shelf 45b is omitted. The member 42 is represented by a two-dot chain line, and members behind it are omitted because the drawing becomes complicated.

In FIG. 5, the moving shelf 45c is a supporting shelf 45.
b, and a lower projection 45f located below and forward of the movable shelf 45c is replaced with a mountain-shaped projection 45 located in the lower front of the supporting shelf 45b.
g to the front. The projection 45g is provided on the support shelf 45.
b is a part of the groove 45d provided on both the left and right sides. The lower projection 45 corresponds to the left-right direction of the mountain-shaped projection 45g.
f is provided at a similar position so as to ride over that part.

Until the state shown in this figure, a sufficient gap is provided between the upper surface of the movable shelf 45c, the lower surface of the support shelf 45b, and other parts in a sliding relationship. The operation force (mainly frictional force) to be moved back and forth is reduced. Therefore, when a storage object is placed on the support shelf 45b in this state, the center of the front end of the support shelf 45b supports the weight of the storage object only by its thickness, and the storage shelf 45b is weakly bent downward. Also, in this state, when the finger near the tip of the moving shelf 45c is pinched with the finger from above and below together with the supporting shelf 45b,
As described above, the tip of the support shelf 45b is bent.

In the conventional structure, even when the movable shelf 45c is completely pushed into the support shelf 45b, the storage condition is similar to that described above, and the storage items are shaken. When the person puts on the image that the mounting state is unstable and makes the user feel weak in terms of strength, and when picking up the front of the supporting shelf 45b and the moving shelf 45c from above and below with a finger, and lifting the tip upward, The tip of the support shelf 45b flexed for the same reason, which also felt weak in strength and lacked in commerciality.

In FIG. 6, the moving shelf 45c is further pushed into the supporting shelf 45b, the lower projection 45f rises along the front slope of the mountain-shaped projection 45g, and the lower projection 45f further moves rearward above the mountain-shaped projection 45g. I do. At this time, the moving shelf 45
The upper end of the shelf sash 45h or the moving shelf 45c that covers the vicinity of the front end of c has an inclined surface near the lower surface of the front end of the supporting shelf 45b, so there is always a gap in that area, and the movement of the moving shelf 45c to the rear is not hindered. . The shelf sash 45h is made of metal (for example, stainless steel) and serves to reinforce the movable shelf 45c. When the shelf sash 45h is further pushed into the support shelf 45b, the support shelf 45b

c is held at a higher position than when the sliding surface 45j slides on the mountain-shaped projection 45g.

Therefore, the gap between the upper surface of the shelf sash 45h and the lower surface of the support shelf 45b is reduced, so that the appearance seen from the front is also beautiful, and in the state of FIG.
When a storage object is placed on the upper shelf b, the vicinity of the tip of the support shelf 45b slightly bends and comes into contact with the upper surface of the lower shelf sash 45h, and the support shelf 45b is moved together with the movable shelf 45c reinforced with the shelf sash 45h. In order to support, the amount of bending near the tip of the support shelf 45b decreases, and the overall strength also increases.

Therefore, in this state, the amount of downward bending of the center of the front end of the supporting shelf 45b is also reduced, and even if a storage object is placed on the supporting shelf 45b, the bending is not conspicuous and the wobble of the storage article is reduced. You. In addition, the moving shelf 4 together with the supporting shelf 45b.
Even when the support shelf 45b is rotated by pinching the vicinity of the tip of the support shelf 45c up and down, the bending of the tip of the support shelf 45b is not much noticeable, and the operability is improved. , And the product does not feel weak in terms of strength, thereby improving the marketability.

Although the shelf sash 45h is provided at the tip of the movable shelf 45c and in the vicinity thereof, even if the movable shelf 45c is formed in the same size instead of the above, the abrasion and the strength are not improved. In other respects, the same effect as described above can be obtained.

Then, the shelf sash 4 is made of a wear-resistant substance such as metal so as to cover the tip of the movable shelf 45c and its vicinity.
By providing 5h, wear of the contact portion with the support shelf 45b can be reduced, and operability can be improved due to a decrease in frictional force. If the shelf sash 45h is a tough body such as a metal, a role of reinforcement is provided. Also.

In the above, the portion corresponding to the upper surface of the shelf sash 45h is raised, the portion corresponding to the lower surface of the shelf sash 45h is lowered, or the upper surface of the support projection 45i is raised. , Upper surface of shelf sash 45h and support shelf 4
When at least a part of the front surface of the lower surface is brought into contact with the mounting portion 5b, the above-mentioned respective effects are further improved. The same effect as described above can be obtained even if the moving shelf 45c is formed in the same size as the shelf sash 45h without the shelf sash 45h.

In this state, when the inclined surface from the lower front end of the mounting portion of the support shelf 45b is extended to near the upper surface of the shelf sash 45h, the movable shelf 45c is moved to the support shelf 45b.
The operability of the movement in the front-rear direction when the button is pushed is further improved.

Further, a part of the mountain-like projections 4 at a lower front portion is formed by grooves 45d provided on both left and right sides of the support shelf 45b.
5g has an inclined surface in the front-rear direction, but even if it is a simple projection, the operation surface is slightly inferior, but a similar effect can be obtained. The effect will be obtained.

Further, the protrusions 45g and the protrusions are eliminated, and a protrusion corresponding to the rise of the movable shelf 45c by the protrusion 45g is provided below both front ends of the movable shelf 45c fitted into the groove 45d. When the movable shelf 45c is pulled out, the front upper surface is set to a position where the movable shelf 45c is kept horizontal when the movable shelf 45c is pulled out.
When the moving shelf 45c is pushed into the supporting shelf 45b, the moving shelf 45c is lifted upward, and the gap is reduced. The effect will be obtained.

In addition, opposing substantially U-shaped and inverted substantially U-shaped grooves 45d, 45d having an opening toward the center are provided on both sides of the support shelf 45b. Although the structure is such that both sides are held so as to be able to be moved in and out at the 45d portion, the fitting relationship between the support shelf 45b and the movable shelf 45c may be reversed.

The same effects as described above can be obtained even if the arrangement order and the positional relationship of the storage compartments such as the refrigerator compartment 11, the vegetable compartment 12, the freezing compartment 13 and the like are different, and the member 42 is replaced with a normal portion. Even in the case of a partition wall made of a resin material or the like, the same effect as described above can be obtained, although there is a reduction in uniform cooling of the storage room.
