DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage,
The present invention relates to a storage that circulates a heat medium around the outer periphery of the storage box and indirectly maintains the inside of the storage box at a constant temperature.

[0002]

2. Description of the Related Art This type of storage includes a refrigerator and a hot storage.
One disclosed in Japanese Patent No. 57576 is known.

In this publication, a storage box is provided in a heat insulating box, and an evaporator of a cooling mechanism and air cooled by the evaporator are blown between the heat insulating box and the storage box. A cooling fan is provided, and a convection fan is provided in the storage box to blow the lower cooling air upward to convection. In such a configuration, when the cooling fan blows the air cooled by the evaporator to the outer periphery of the storage box, the air in the storage box is cooled through the wall material of the storage box, and the fresh food and the like stored in the storage box. Is indirectly cooled.

Then, the convection fan blows the cool air, which tends to be stagnant downward in the storage box in the natural state, upward, so that the temperature in the storage box is made uniform. Also, Japanese Unexamined Patent Publication No. 2-263
No. 084 discloses a double structure comprising such a heat-insulating box and a storage box, and a dew receiving plate disposed substantially in parallel with a top plate of the storage box at a small distance. There is disclosed a refrigerator in which a temperature sensor is disposed between a top plate and a dew receiving plate, and a digital display for displaying a detection result of the temperature sensor is disposed on a front surface of the main body.

In such a configuration, the inside of the storage box is indirectly cooled by the cooled air blown to the outer periphery of the storage box, and the top plate and the dew receiving plate in the storage box are detected by the temperature sensor. Based on the temperature in between, a digital display indicates the temperature in the storage box on the front of the main body.

[0006]

The refrigerator in which the inside of the storage box is indirectly cooled as described above has a feature that the inside of the storage box is maintained at a high humidity. It is found that circulating the air is suitable for shortening the time required to defrost a large frozen product.

[0007] However, in the conventional refrigerator, there is only an air flow that merely allows convection of the air in the refrigerator, and a predetermined air flow suitable for thawing cannot be sent. Further, even if a fan having a predetermined air volume is simply provided, when the frozen product is stored in the storage box, air cooled on the surface of the frozen product is circulated in the storage box by the internal fan, The temperature inside the storage box is made uniform and drops rapidly, which may cause refrigeration obstacles to other storage items. On the other hand, if a plurality of storage chambers are formed, the temperature control of each chamber becomes extremely complicated, and it becomes impossible to easily maintain a uniform temperature.

Also, when displaying the temperature in the storage box, if there is a difference in the temperature in each room, the user doubts the reliability of the display, or if the display is broken. I have to think . The present invention has been made in view of the above problems, one promoting quality thawing, and an object thereof is to provide a refrigerator capable of facilitating temperature control.

[0009]

To achieve the above object, according to an aspect of a refrigerator according to a first aspect of the invention, between predetermined in insulating box
Storage box with the air flow circulation passage in the gap
By partitioning the inside of the box by the partition walls of the heat conductive member,
A plurality of storage chambers formed so as to allow thermal interference, a temperature detection means disposed in any of the plurality of storage chambers, and a temperature detection means disposed in a storage chamber other than the storage chamber in which the temperature detection means is disposed. It is configured to include an internal fan for circulating air, and a cooling mechanism for maintaining the internal temperature of the storage chamber at a predetermined temperature based on the temperature detected by the temperature detecting means.

According to a second aspect of the present invention, in the first aspect, the inside of the storage room in which the temperature detecting means is disposed.
It is configured to include temperature display means for displaying temperature .

[0011]

According to the first aspect of the present invention, a plurality of storage chambers which mutually interfere with each other are provided, and a cooling chamber is provided in the storage chamber having the internal fan.
When a frozen clot is stored, only the temperature in the storage room changes rapidly. In other storage rooms, the temperature does not change rapidly, and the cold heat of the frozen mass is gradually transmitted by heat interference. After a lapse of a predetermined time, the cold heat is transmitted to the other storage rooms, and the temperature of all the rooms becomes substantially constant. As described above, since the storage rooms are basically in a relationship of thermal interference, it can be assumed that all the rooms have a constant temperature, and if the temperature control is performed based on the internal temperature of the storage room having no internal fan, the entire system is controlled. Temperature control can be performed.

Further, in the invention according to claim 2 configured as described above, similarly, it is assumed that all the rooms have a constant temperature, and the internal temperature of the storage room having no internal fan is set to the whole temperature. It is displayed as a representative temperature.

[0013]

As described above, according to the present invention, the storage chambers having a relationship of thermal interference with each other are provided with the internal fan to actively exchange heat and the other storage chambers are provided with the internal fan. The temperature is controlled based on the temperature in the storage room where the temperature change is relatively small, so that it is possible to facilitate the control while promoting thawing or to display an appropriate temperature. A possible storage can be provided.

[0014]

The storage box 20 is formed of a metal plate material such as stainless steel, which is a heat conductive member, in a housing shape having an opening 21 on one surface.
The openings 14a and 14b of the heat insulating box 10 are fixed to and supported by the outer peripheral edge of the inner surface of the front wall as desired. At this time, the left and right side walls 22, 23, the top wall 24, the bottom wall 25, and the rear wall 26 of the storage box 20 are respectively held at predetermined intervals from the inner wall of the inner box 12 in the heat insulating box 10, and the gap is formed by the air flow. A circulation passage W is formed.

In the storage box 20, a partition wall 27 made of a stainless metal plate material, which is a heat conductive member, is fixed to an upper wall 24 and a bottom wall 25 of the storage box 20 at an upper side and a lower side. The inside is divided into a right room (storage room) RM1 in the figure and a left room (storage room) RM2 in the figure. The partition 27 and the storage box 20 do not necessarily need to be sealed. Further, in the present embodiment, the partition wall 27 is formed of a flat plate. However, the partition wall 27 may be formed of a plate material having a large surface area such as a corrugated plate to improve the heat exchange efficiency. Both chambers formed in this way
Heat exchange is actively performed between the RM1 and RM2 via the wall material, and the RM1 and RM2 interfere with each other.

The two in-compartment fans 30a and 30b are each constituted by fixing a fan 32 to the rotation axis of a fan motor 31 and attached to the left wall 22 via a support member so as to face the partition wall 27. Have been. Further, a cover 40 for forming a predetermined air flow path is attached to the front surfaces of the in-compartment fans 30a and 30b, and the cover 40 has an exhaust port 41 at a portion facing the fan 32.
Are formed, and a suction port 42 is formed in the lower part. That is, the end of the upper side of the cover 40 is
, The end of the left side bent as an L-shaped cross section is in contact with the left side wall 22 of the storage box, the end of the right side is in contact with the rear wall 26 of the storage box 20, and the lower side is a predetermined gap with the left side wall 22. Are formed to form the above-mentioned suction port 42.

The left side wall 2 of the storage box 20 in the heat insulation box 10
The evaporator 51 of the cooling mechanism 50 is fixed to the wall portion facing the upper surface 2 with its air flow path directed vertically, and the upper part between the evaporator 51 and the left side wall 22 of the storage box 20 has air A circulation hole 61 is formed, and a shielding plate 60 in which a blower fan 62 is disposed in the air circulation hole 61 is fixed at its upper piece so as to hang down from the upper wall of the inner box 12 in the heat insulating box 10. A sufficient gap is formed between the lower side of the shielding plate 60 and the lower wall of the inner box 12, and an air cooling flow path communicating from the gap to the upper air flow hole 61 via the air flow path of the evaporator 51. Is formed.

As shown in FIG. 5, the cooling mechanism 50 includes a compressor 52 for compressing the refrigerant, a condenser 54 for condensing the compressed refrigerant under the air-cooling action of the air-cooling fan 53, and a condensed condenser. A dryer 55 for dehumidifying the refrigerant; a capillary tube 56 for converting the dehumidified condensed refrigerant into a low-temperature low-pressure refrigerant; 51, and the components other than the evaporator 51 are housed in the auxiliary box 10a. In the figure, a hot gas valve 57 for supplying high-temperature compressed refrigerant compressed by the compressor 52 during defrosting to the evaporator 51 is connected to a pipe connecting the output side of the compressor 52 and the input side of the evaporator 51. Has been interposed.

The compressor 52 includes a compressor motor 5
2a and a compression mechanism 52b driven by being connected to the rotation axis of the compressor motor 52a.
The drive of the compressor motor 52a is controlled by a sequence control circuit 71 in an electric control circuit 70 as shown in FIG. Note that these electric control circuits 7
0, the cooling mechanism 50, the blower fan 62 and the like constitute a heat exchange mechanism.

The electric control circuit 70 is connected to a commercial AC power supply, and a main power switch 72 for opening and closing the commercial AC power supply and the internal power supply paths PW1 and PW2;
2, the temperature display circuit 17, the internal fans 30a and 30b, and the blower fan 62, which are connected in parallel to the power supply paths PW1 and PW2, respectively, and the temperature sensor Th.
1 and Th2, and the sequence control circuit 71 for controlling the temperature in the chambers RM1 and RM2.

The sequence control circuit 71 includes a series circuit S1 in which a temperature sensor Th1 that is turned on when the internal temperature T1 in the chamber RM1 is equal to or higher than a set upper limit temperature TH and an exciting coil of the relay R1 are connected in series. Temperature sensor Th that conducts when the internal temperature T1 becomes equal to or lower than the set lower limit temperature TL.
A series circuit S2 in which the excitation coil of the relay R2 and the exciting coil of the relay R3 are connected in series;
3 is connected in series with a make-up contact R2-2 of the relay R2 and a break contact R4-2 of the relay R3 in parallel with each other.
The relay R2 including R4-3 and R2-3 and the self-holding circuits S4 and S5 of the exciting coil in the relay R4 are connected to the power supply paths PW1 and PW2.

The temperature sensors Th1 and Th2 are integral sensors configured to change the conduction state between the two sets of contacts at the set upper limit temperature TH and the set lower limit temperature TL as described above. These temperature sensors Th1, Th
The temperature sensor Th3 and the temperature sensor Th3 described above are mounted above a chamber RM1 in which the in-compartment fans 30a and 30b are not installed, of the two chambers formed by the partition wall 27.

Next, the operation of this embodiment having the above configuration will be described. After the refrigerator is installed, the main power switch 72
Is turned on, power is supplied to the temperature display circuit 17, which inputs the detection signal of the temperature sensor Th3 and causes the digital display 16 to display the internal temperature T1 in the room RM1. Although the chamber RM1 and the chamber RM2 are partitioned by a partition wall 27, since the partition wall 27 is formed of a heat conductive member, the inside temperatures T1, T in both the chambers RM1, RM2.
There is no difference between the two. Accordingly, the inside temperature T of the room RM1 indicated by the digital display 16 in front of the auxiliary box 10a.
1 may be the temperature in the storage box 20.

On the other hand, the internal temperature T in the chambers RM1 and RM2
Since both T1 and T2 are equal to or higher than the set upper limit temperature TH, the temperature sensor Th1 is turned on to energize the exciting coil of the relay R1. Then, the make contacts R1-1 and R1-2 in the self-holding circuit S4 of the relay R2 are turned on, and the exciting coil of the relay R2 is energized, so that the make contact R2-1 is turned on and the relay R2 is held in the on state. Let me know.

When the relay R2 is turned on, the make contact R2
-2 conducts, and the compressor motor 52a and the air-cooling fan 53 are energized via the break contact R4-2 of the relay R4, and the cooling mechanism 50 starts. On the other hand, at the same time, the blower fan 62 also starts blowing air, sucking air from the gap between the lower side of the shielding plate 60 and the lower wall of the inner box 12 through the air flow path of the evaporator 51, and From the air circulation hole 61 to the air circulation path W formed around the storage box 20. Therefore, the cooling mechanism 50
Is started, the air sucked by the blower fan 62 exchanges heat when passing through the air flow path of the evaporator 51, and the cooled air flows from the air circulation hole 61 to the air circulation path formed around the storage box 20. It is blown to W.

Since the storage box 20 is formed of a heat conductive member, when cooled air is blown to the outer periphery, each wall 22
Heat exchange is carried out at -26, and the temperature inside the chambers in the chambers RM1 and RM2 gradually decreases. Then, even if the internal temperature T1 is lower than the set upper limit temperature TH and the temperature sensor Th1 is turned off, the operation of the cooling mechanism 50 is continued because the relay R2 is on and held by itself.

However, when the internal temperature T1 falls below the set lower limit temperature TL, the temperature sensor Th2 is turned on, and the relay R3
Energize the excitation coil. Then, as in the case of the above-described series circuit S4, the relay R4 is turned on, the break contact R4-3 constituting the forced release circuit of the relay R2 is turned off, and the self-holding state of the relay R2 ends. Since the ON state of the relay R4 is self-held similarly to the case of the relay R2, the break contact R4-2
Is turned off, and the make contact R2-2 is also turned off. Therefore, the compressor motor 52a and the air cooling fan 5
3 and the power supply to the blower fan 62 are stopped, and the cooling mechanism 50
The operation is also canceled.

Hereinafter, the sequence control circuit 71 will be described with reference to FIG.
Is controlled so as to maintain the inside temperature T1 within the range between the set upper limit temperature TH and the set lower limit temperature TL as shown in FIG. During this time, the temperature sensor Th3 detects the internal temperature T1 in the room RM1, and the digital display 16 displays the internal temperature T1 that changes between the set upper limit temperature TH and the set lower limit temperature TL. .

By the way, the above set upper limit temperature TH and the set lower limit temperature TL in the refrigerator are adjusted within a range of several degrees with reference to about 0 degree Celsius, but the room RM1 is used as a normal refrigerator and the room RM2 is used. It shall be used as a thawing chamber exclusively for thawing. In the room RM2, the fan 30
The air is circulated by the functions of a and 30b, and strong wind is blown over the entire area of the refrigerator. When the frozen mass frozen at -20 degrees Celsius or less is accommodated in the room RM2, the air flow is cooled when flowing along the surface of the frozen mass, and the cooled air circulates in the room RM2. As a result, the internal temperature T2 sharply decreases as shown by the dashed line in FIG.

On the other hand, the internal temperature T1 in the chamber RM1 also decreases as shown in the figure, and when the temperature falls below the set lower limit temperature TL, the compressor motor 52a and the air cooling fan 5
3 is stopped, and the cooling operation of the cooling mechanism 50 is released. However, even if the cooling operation of the cooling mechanism 50 is canceled, the blower fan 62 continues to blow air. By the way, the in-compartment fans 30a and 30b blow the air in the compartment toward the partition wall 27, and when the air cooled by the frozen mass flows along the surface of the partition wall 27 in the chamber RM2, the partition wall 27 is moved. Cold air is supplied into the chamber RM1 via the RM1 to cool the air in the chamber RM1. In addition, the cold heat in the chamber RM2 is transmitted to the air in the air flow circulation passage W via the upper wall 24 and the bottom wall 25, and the cold heat of the air in the air flow circulation passage W is further transferred to the upper wall 24, the left wall 23, and the bottom wall. The air in the chamber RM1 is cooled through the wall 25.

Therefore, even if the internal temperature T1 becomes equal to or lower than the set lower limit temperature TL and the cooling operation of the cooling mechanism 50 is released, the internal temperature T2 in the chamber RM2 is lowered by the frozen mass as described above. The inside of the chamber RM1 is also cooled by the cold heat. That is, when the frozen mass is thawed, the cooling mechanism 50 does not need to be operated for cooling, and instead of the evaporator 51, the chamber RM2 is used.
Since the cooling heat in the inside is released into the air circulation path W by the walls 24 and 25, the blower fan 62 is operated irrespective of the cooling operation of the cooling mechanism 50, so that the air in the air circulation path W The air is cooled and the inside of the chamber RM1 can be cooled.

FIG. 8 shows the relationship between the temperature of the frozen mass (Tf), the temperature in the chamber RM2 (T2), and the temperature in the chamber RM1 (T1). In the drawing, when the internal temperature T1 gradually increases and the internal temperature T1 reaches the set upper limit temperature TH, the compressor motor 52a in the cooling mechanism 50 and the air cooling fan 5
3, and the inside temperature T1 is gradually reduced. At this time, the frozen mass with extremely low temperature is placed in room RM2.
The temperature T2 in the refrigerator falls sharply by
Also in the room RM1, the room RM2 in which the internal temperature T2 has dropped.
And the cooling by the operation of the cooling mechanism 50 gradually lowers the internal temperature T1. And the internal temperature T
When 1 becomes lower than or equal to the set lower limit temperature TL, the operation of the cooling mechanism 50 is released.

Even if the operation of the cooling mechanism 50 is canceled, the chamber RM2
Although the inside of the room RM1 is cooled by the cold heat inside the room, in this room RM2, the air on the surface of the frozen mass is cooled down to near the same temperature, but the room fans 30a and 30b function to cool the room.
The air in RM2 is forcibly circulated, and the temperature T2 in the refrigerator becomes sufficiently higher than the temperature of the frozen mass and lower than the set lower limit temperature TL. When the inside of the room RM1 is cooled, it is not cooled by the extremely low-temperature air cooled on the surface of the frozen mass, but is cooled by the air circulated in the room RM2 and having a certain temperature rise. , Room RM1
The temperature inside does not drop sharply like the temperature inside the chamber RM2.

Accordingly, the digital display 16 displays the temperature T1 which decreases relatively slowly, instead of the temperature T2 which decreases rapidly, and the user is disturbed by seeing the temperature display. Never do. That is, if the temperature control is performed based on the temperature inside the thawing box and the temperature inside the thawing box where the temperature drops significantly during thawing is displayed, the user may feel uneasy about the reliability of the apparatus. By displaying the temperature on the side where there is not much change at a higher temperature as described above, the user does not have to worry about the reliability of the apparatus.

While the chamber RM2 cools the air in the air flow passage W, the cold of the frozen mass gradually decreases.
The temperature Tf of the frozen mass rises because it is robbed by the air inside. Therefore, as the thawing of the frozen mass proceeds, the internal temperature T2 in the room RM2 also increases, and the internal temperature T1 of the room RM1 cooled by the cold of the room RM2 also gradually increases. At this time, it is clear that the internal temperature T1 of the room RM1 is higher than the internal temperature of the room RM2.
No. 1 rises to the set upper limit temperature TH first, and when the temperature exceeds the set upper limit temperature TH, the cooling mechanism 50 is started.

Thereafter, the two chambers RM1 and RM2 are not cooled by the frozen mass but are cooled by the cooling mechanism 50. Then, the inside temperature T1 of the chamber RM1 is controlled so as to maintain the range between the set upper limit temperature TH and the set lower limit temperature TL, and the digital display 16 displays the inside temperature T1. Also, the room RM2 becomes a normal refrigerator, and stores the frozen mass that has been thawed.

In the present invention, the internal fans 30a, 3
Although the temperature control was performed based on the internal temperature T1 of the room RM1 where no 0b is disposed, if the temperature control was performed based on the internal temperature T2 of the room RM2 serving as the thawing box, the temperature change at the end of thawing would be caused. Are as shown in T1-1 and T2-1 in FIG. That is, since the temperature T2 in the chamber RM2 in which the frozen mass is stored should be lower than the temperature T1 in the room RM1 in which the frozen mass is not stored, the internal temperature T2 becomes the set upper limit temperature TH. When the cooling mechanism 50 is started, the internal temperature T1 exceeds a range suitable for preserving the food, which causes discoloration or deterioration of the food.

During normal refrigeration, the inside temperature T1 of the room RM1 and the inside temperature T2 of the room RM2 are almost the same, but the air flow holes 61 through which the blower fan 62 blows cool air.
The room RM2 closer to the chiller comes into contact with the cold air first, so that heat exchange is easily performed. For this reason, the temperature T2 in the chamber RM2 is lower even in normal times, and even if temperature control is performed based on the temperature T1 in the chamber RM1, the temperature T2 in the chamber RM2 is inappropriate for storing food. The temperature will not be too high.

In the above-described embodiment, the case where thawing is performed in a refrigerator is described. However, the storage of the present invention can be used as follows. Instead of using chamber RM2 for thawing, it can also be used for quick freezing. When a food having a temperature higher than the internal temperature is stored in the room RM2, the internal fans 30a and 30b blow a strong wind of cooled air around the food, so that the food can be rapidly cooled. In this case, the internal temperature T2 in the room RM2 rises due to the latent heat of the food, and the temperature change is transmitted to the room RM1 via the partition wall 27, so that the room RM1
The temperature control is performed based on the temperature T1 in the refrigerator 1 as a reference.

In such a case, if the temperature is controlled based on the internal temperature T2 in the chamber RM2, the internal temperature T2 rises immediately after the food is stored, and the cooling mechanism 50 is operated. The chamber RM1 in which the temperature T1 has not changed will be cooled too much. However, by performing temperature control based on the internal temperature T1 of the room RM1 where the internal fans 30a and 30b are not installed as in the present invention,
Even if the internal temperature T2 in the chamber RM2 temporarily rises due to the rapid cooling, the cooling mechanism 50 is not immediately activated to prevent a situation in which the inside of the chamber RM1 is too cold.

In addition, the storage can be used not as a refrigerator but as a storage. in this case,
A heater may be provided instead of the evaporator 51 in the cooling mechanism 50, and warm air may be blown into the air circulation path W by the blower fan 62. In such a configuration, the in-compartment fans 30a and 30b blow air around the dishes that are too hot to take away heat, and warm the inside of the room RM2 via the partition wall 27.

On the other hand, in the above-described embodiment, the cooling operation of the cooling mechanism 50 is controlled by the sequence control circuit 71 based on the detection results of the temperature sensors Th1 and Th2. May be used, and the microcomputer may perform software control to perform temperature control based on the detection result of the temperature sensor, or perform other accompanying control such as defrost control. The temperature sensors Th1 and Th2 are not limited to the on / off type, and may be a thermistor whose resistance changes in response to a temperature change.

In the above embodiment, the inside of the storage box is divided into two parts. However, the number of divisions is arbitrary, for example, a thaw box is arranged at the center and divided into three parts. At this time, an in-compartment fan is installed in the small room on the side where cold air comes in contact first for each of the small rooms in parallel. Also, the direction of division is arbitrary, such as vertical division instead of left / right division.

In the above-described embodiment, two fans 30a and 30b are arranged vertically, but only one fan may be arranged below and the air may be blown upward.
