In the refrigerator 1, an inner box 2 b is arranged inside an outer box 2 a that covers the outside, and a gap between the outer box 2 a and the inner box 2 b is filled with a heat insulating material 2 c such as foamed polyurethane. The front surface of the refrigerator compartment 11 covered with the inner box 2 b can be opened and closed by the heat insulating door 3.
[0003]
An ice greenhouse 14 as an isolation room is provided below the refrigerator compartment 11, and a vegetable compartment 12 is disposed below the ice greenhouse 14. The front of the vegetable compartment 12 can be opened and closed by a sliding heat insulating door 4. The refrigerator compartment 11 and the vegetable compartment 12 are partitioned by partition plates 31 and 32 made of resin molded products. The partition plate 32 is provided with a through hole 32a.
[0004]
A cool air passage 28 through which cool air generated by a cooler (not shown) flows is provided behind the refrigerator compartment 11 and the ice greenhouse 14.

A back plate 35 facing the cold air passage 28 is provided on the back surface of the ice greenhouse 14 via a heat insulating material 36.
[0005]
The cold air flows into the refrigerating chamber 11 through the openings 42 a and 36 a provided in the member 42 and the heat insulating material 36, and cools the inside of the refrigerating chamber 11. Then, the cold air descends due to its own weight, and forms an air flow that flows into the vegetable compartment 12 from the through hole 32a through the cold air passage 30. Thereby, the inside of the vegetable compartment 12 is cooled.
[0006]
The member 42 is made of a metal plate or the like, and transmits the cold heat generated by the cold air flowing through the cold air passage 28 to be discharged into the refrigerator compartment 11.

Further, while the cooler is stopped, the accumulated cold heat is discharged to keep the inside of the refrigerator compartment 11 cool.
[0007]
[Problems to be solved by the invention]
However, according to the above-described conventional refrigerator, if the temperature difference between the inside of the refrigerator compartment 11 and the inside of the cold air passage 28 is large, condensation occurs on the surface of the member 42 on the refrigerator compartment 11 side. Thereby, the inside of the refrigerator compartment 11 is dried. Water droplets due to condensation flow down the surface of the member 42 and accumulate at the bottom of the ice greenhouse 14.
[0008]
Thereafter, the water droplets accumulated at the bottom of the ice greenhouse 14 are evaporated by the air flow passing therearound. Water vapor by evaporation is guided by the air flow and flows into the vegetable compartment 12 through the through hole 32a. For this reason, the inside of the refrigerator compartment 11 remains dry, and there is a problem that food stored in the refrigerator compartment 11 deteriorates quickly.

The condenser and the cooler 25 are connected via a first capillary tube (not shown). A second capillary tube (not shown) is disposed between the coolers 21 and 25.
[0022]
Thus, a refrigeration cycle is configured, 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.
[0023]
Further, switching means is provided between the condenser and the first capillary tube, and the switching means and the cooler 21 are connected via a third capillary tube (not shown). And only the cooler 21 can be cooled by switching the switching means.
[0024]
The cooler 21 is disposed in the 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 cold air passage 23 communicates with the freezer compartment 13 through an inlet 13a and an outlet 13b to the freezer compartment 13 provided in the back plate 33a.
[0025]
The cooler 25 is disposed in the cold air passage 27. The lower part of the cold 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 overcooling of the vegetable compartment 12 that is provided close to the cooler 25. A blower 26 is disposed above the cooler 25 in the cool air passage 27. The cold air passage 27 communicates with the vegetable compartment 12 through the outlet 12b.
[0026]
The upper part of the cold air passage 27 is formed by a heat insulating member 36 fixed to the back plate 35 of the ice greenhouse 14 and the inner box 2b. The heat insulating member 36 is provided with an opening 36a. If the front view of the refrigerator compartment 11 is shown in FIG. 2, the opening part 35a is provided in the back plate 35 in the same position as the opening part 36a. The ice greenhouse 14 communicates with the cold air passage 27 through the openings 35a and 36a.
[0027]

[0028]
FIG. 3 shows a detailed view of the blower 29 portion. In the cool air passage 28, the air taken in from the refrigerator compartment 11 by the blower 29 through the opening 41a and the cool air flowing through the cool air passage 27 by the blower 26 are mixed. It has become.
[0029]
The cold air passage 28 in the rear portion of the refrigerator compartment 11 is formed by a member 42 that forms 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, aluminum alloy or stainless steel having good workability and high antirust effect).
[0030]
This makes it possible to store cold and release cold. In addition, when the thickness of the said heat conductive member is thick, cold storage capacity goes up and intensity | strength also increases. When the thickness is small, the efficiency of releasing cold heat increases, which is advantageous for weight reduction. Therefore, a thin plate material or a thick plate material may be selected and provided at an appropriate place according to the purpose.
[0031]
As shown in the front and sectional views of FIGS. 6 and 7, the surface of the member 42 is provided with uneven portions 42 j and 42 k that extend horizontally by press working or the like. Thus, the strength of the member 42 is reinforced, and the surface area is increased to increase the amount of cold storage and the release of cold heat, thereby improving the cooling efficiency.
[0032]
Furthermore, when the number of times of opening and closing the heat insulating door 3 is large and the temperature and humidity in the refrigerator compartment 11 are extremely increased, dew condensation occurs on the surface of the member 42 to dry the inside of the refrigerator compartment 11. At this time, water droplets due to condensation do not flow down but are accumulated and held on top of the convex portion 42j '. Moreover, it is held by the surface tension at the pattern cut 42m by the uneven portion 42j.
[0033]
Thereafter, when the blowing of the cool air in the cool air passage 28 cooled by the cooler 25 is stopped, water droplets captured by the uneven portions 42j of the member 42 are evaporated into the dry refrigerator compartment 11, and the inside of the refrigerator compartment 11 is humidified. . Therefore, moisture does not flow out of the refrigerator compartment 11, the humidity in the refrigerator compartment 11 is maintained, and the member 42 functions as a moisture retaining member. If the recess 42k 'is arranged on the refrigerator compartment 11 side, water droplets are easily collected, and the moisture retention capacity is further improved.
[0034]
Further, as shown in FIGS. 8 and 9, the concave and convex portions 42j and 42k may be formed in an intermittently inclined pattern. Even in this case, water droplets due to condensation do not flow down but are held by the surface tension at the pattern cuts 42m formed by the uneven portions 42j.
[0035]
Further, as shown in FIG. 10, the uneven portion 42n may be formed by projecting or recessing characters or symbols such as “bottled corner” or “hors d'oeuvre corner” on the refrigerator compartment 11 side of the member 42. A pattern shaped like a bottle or hors d'oeuvre may be formed. By these, the same effect can be obtained, and since a visual message can be transmitted to the user, the usability of the refrigerator is improved.
[0036]
Detailed cross-sectional views of the upper and lower end portions of the member 42 are shown in FIGS. According to these drawings, the member 42 includes a tap plate (not shown) provided in the inner box 2b, a mounting member 71 fixed to the inner box 2b by a screw 72, and a mounting portion 35b provided in the back plate 35. Locked. When the lever portion 71a of the mounting member 71 is pushed up with fingers, the engagement of the claw portion 71b is released.
[0037]
In this state, the member 42 can be attached and detached by tilting the upper part of the member 42 forward and pulling it upward, so that the member 42 is detachable. As a result, the cold air passage 28 and the member 42 can be easily cleaned on the cold air passage 28 side. The lower part of the member 42 is hermetically sealed with a sealing material 73 fixed to the heat insulating member 36.
[0038]
The lower end portion of the member 42 may be as shown in FIG. That is, a water reservoir 35 d (collecting part) is integrally formed at the upper end of the back plate 35 and installed so as to receive the member 42. By doing in this way, even if the water droplet which could not be hold | maintained by the uneven | corrugated | grooved part 42j (refer FIG. 6) of the member 42 flows down, it is stored in the water pool part 35d. And when the member 42 approaches the temperature in the refrigerator compartment 11, the water droplet caught by the water pool part 35d will evaporate, and the inside of the refrigerator compartment 11 will be humidified. Therefore, the outflow of moisture in the refrigerator compartment 11 can be further prevented.
[0039]
The cool air passage 28 in the ceiling portion of the refrigerator compartment 11 is formed by an upper plate 43 made of a resin molded product and the inner box 2b. The member 42 and the upper surface plate 43 are provided with openings 42a and 43a (see FIG. 2). In addition, an illuminating lamp 51 covered with a transparent illumination cover 53 is provided at the center of the top surface of the refrigerator compartment 11.
[0040]
When the top sectional view of the refrigerator compartment 11 is shown in FIG. 4, the member 42 extends in the vertical direction and is supported on the back by a protrusion 28a formed on the inner box 2b. Thereby, the bending of the member 42 against the pressing force from the front surface is prevented, and the cool air passing through the cool air passage 28 is rectified to mute and improve the blowing efficiency. Further, a deodorizing unit 50 is provided in the cold air passage 28. The deodorization part 50 consists of deodorizing agents, such as activated carbon, and may arrange | position the member and apparatus which can perform another deodorizing method.
[0041]
In the refrigerator 1 having the above configuration, when the blower 22 is driven, the air in the freezer compartment 13 is guided to the cold air passage 23 from the outlet 13b. The air is cooled by exchanging heat with the cooler 21 and flows into the freezer compartment 13 from the inlet 13a. Thereby, the inside of the freezer compartment 13 is cooled.
[0042]
When the blowers 26 and 29 are driven, the air in the vegetable compartment 12 is guided to the cold air passage 27 from the outlet 12b. The air is cooled by exchanging heat with the cooler 25 and mixed with the air in the refrigerator compartment 11 guided to the cold air passage 28 from the opening 41a. Thereafter, it flows through the cold air passage 28 and flows into the refrigerator compartment 11 from the openings 42a and 43a. A part of the cold heat generated by the cold air flowing through the cold air passage 28 is released as cold heat into the refrigerator compartment 11 through the member 42. Thereby, the inside of the refrigerator compartment 11 is efficiently and uniformly cooled by the cold heat from the member 42 and the cold air from the openings 42a and 43a.
[0043]
The air in the refrigerator compartment 11 passes between the shelves 45 and the front of the shelves 45, circulates through the cold air passage 30 from below the ice greenhouse 14 through the opening 32 a, and flows into the front of the vegetable compartment 12. Furthermore, the inside of the vegetable compartment 12 is cooled from the front of the storage container 54 through the lower part. Then, the cool air circulates through the outlet 12b to the lower part of the cooler 25.
[0044]
Based on the detection result of the temperature sensor (not shown), the compressor 20 and the blower 26 are operated and stopped, and the temperature of the refrigerator compartment 11 and the vegetable compartment 12 is maintained at 3 ° C., for example. A part of the cold air flowing through the cold air passage 27 flows into the ice greenhouse 14 from the openings 35a and 36a. As a result, the inside of the ice greenhouse 14 can be cooled to a lower temperature and maintained at, for example, -1 ° C.
[0045]
When the cooling in the cooler 25 is stopped and one or both of the fans 26 and 29 are operated, the cold air passing through the cooling passage 28 is cooled by the cold heat accumulated in the member 42. And the inside of the refrigerator compartment 11 is cooled with this cold air. When the blower 26 is operated, the cooler 25 can be further defrosted to humidify the refrigerator compartment 11.
[0046]
According to the present embodiment, the member 42 functions as a heat conduction plate that conducts a part of the cold heat of the cold air passing through the cold air passage 28 and releases it from the entire surface into the refrigerator compartment 11. Therefore, the refrigerator compartment 11 is uniformly cooled by the cold heat uniformly discharged from a large area.
[0047]
Further, the member 42 may be a cold storage member in which a jelly-like or liquid cold insulating material 42c as shown in FIG. 14 is enclosed by packaging materials 42f and 42g. Although the uneven portions as shown in FIG. 6 are formed on the surfaces of the packaging materials 42f and 42g, the uneven portions are omitted in the drawing. If it does in this way, the member 42 will be cold-stored more by the cold heat | fever of the cold air which distribute | circulates the inside of the cold passage 28, and it discharge | releases as cold heat according to the temperature distribution in the refrigerator compartment 11. Therefore, the refrigerator compartment 11 is cooled uniformly.
[0048]
Furthermore, the cool storage member can absorb heat and dissipate heat while the compressor 20 is stopped or the temperature of the cool air in the cool air passage 28 varies, so that the cool air temperature in the cool air passage 28 can be maintained. At this time, since the cold storage member forms the inner wall of the refrigerator compartment 11, it is not necessary to separately provide a member for forming the inner wall, and the space of the refrigerator compartment 11 can be widened to save the space of the refrigerator 1. More preferably, the packaging materials 42c and 42d are made of aluminum alloy or stainless steel having thermal conductivity.
[0049]
And by providing the same uneven | corrugated | grooved part 42j and 42k as the above-mentioned FIG. 6 on the surface of the packaging materials 42f and 42g, while reinforcing the intensity | strength of the member 42, the surface area is increased and the discharge | release amount of cold storage or cold heat is increased. The cooling efficiency is improved. Furthermore, the water storage member by dew condensation is retained and the cold storage member functions as a moisturizing member, and drying in the refrigerator compartment 11 can be prevented.
[0050]
Further, the cold air generated at a low temperature by the cooler 25 is slightly heated by mixing with the air in the refrigerator compartment 11. Thereby, the dew condensation and freezing which arise in the member 42 can be prevented, and drying of the refrigerator compartment 11 and the vegetable compartment 12 can be prevented.
[0051]
And the cooler 25 which cools the refrigerator compartment 11 and the vegetable compartment 12, and the cooler 21 which cools the freezer compartment 13 are provided, and the temperature of the cool air which distribute | circulates the cool air passages 27 and 28 is made into the temperature of the cool air in the cool air passage 23 It can be set higher. Thereby, the dew condensation and freezing which generate | occur | produce in the member 42 can be prevented more, and drying of the refrigerator compartment 11 and the vegetable compartment 12 can further be prevented.
[0052]
Further, the member 42 is erected on the back surface of the refrigerator compartment 11 and extends in the vertical direction. For this reason, even if dew condensation occurs on the member 42 and a water droplet is generated, it does not drop directly on the stored item. Therefore, a good preservation state can be maintained without damaging the stored product. Further, if a fence-like protective wall having a porous property (for example, a small hole, a round hole, etc.) capable of air circulation is provided in front of the member 42, the member 42 can be further thinned, so that the effect of releasing cold is improved. It will also prevent scratches and damage.

The member 42 may be a cold storage member as shown in FIG.
[0068]
In the present invention, when a part of the cold due to the cold air passing through the cold air passage is released into the storage chamber through the member, a part of the cold air passing through the cold air passage absorbs heat from the member to cool the member, It means that the member absorbs heat from the storage chamber and cools the storage chamber.
[0069]
【The invention's effect】
According to the present invention, when the temperature difference between the cold air passage and the storage chamber is large, water droplets adhering to the moisture retention member due to condensation are retained by the moisture retention member. Thereafter, when the temperature in the cold air passage and the storage chamber approach, water droplets captured by the moisture retention member evaporate and humidify the storage chamber. Therefore, moisture does not flow out of the storage chamber, and the humidity in the storage chamber can be maintained to prevent drying.
[0070]
According to the present invention, the moisturizing member conducts or stores a part of the cold heat of the cold air passing through the cold air passage and releases it from the entire surface into the storage chamber. Therefore, the storage chamber is uniformly cooled by the cold heat uniformly discharged from a large area.
[0071]
Further, according to the present invention, the water droplets due to dew condensation are not allowed to flow down but are retained in the upper part by surface accumulation or surface tension by the uneven portions provided on the surface of the moisture retention member. Then, when the retained water droplets evaporate, it can be easily humidified to prevent drying in the storage chamber. Furthermore, the strength of the moisturizing member can be reinforced and the surface area can be increased to increase the amount of cold storage and the release of cold heat, thereby improving the cooling efficiency.
[0072]
Further, according to the present invention, since the concavo-convex portion is formed in the horizontal direction, it is possible to easily retain moisture by accumulating water droplets on the upper portion. In addition, according to the present invention, since characters, symbols, and designs are formed by the concavo-convex portions, moisture can be kept and a visual message can be transmitted to the user, and the convenience of use of the refrigerator is improved.
[0073]
Further, according to the present invention, since the water droplets that could not be captured by the moisture retaining member are collected by the collection unit, the outflow of moisture from the storage chamber can be further prevented, and drying can be further prevented.
