[0002]

2. Description of the Related Art In recent years, there has been an increasing need for large capacity refrigerators. On the other hand, due to the housing situation, the installation space is limited due to the increase in the size of the refrigerator, and in order to increase the capacity, the void space inside the refrigerator body and the space with low practicality are reviewed and the volume efficiency is reduced by reducing these. It is required to increase the effective internal volume without increasing the installation space.

There are various approaches to improving the volumetric efficiency. There are various methods for improving the heat insulating performance of the heat insulating material of the refrigerator body to directly increase the internal volume of the refrigerator, a refrigeration cycle for cooling the internal space, A typical method is to reduce the occupied volume of components that are indispensable for the cooling function parts such as the blower, damper device, cooling air path, and the electronic control board, but become ineffective for the storage space in the refrigerator. It is an initiative.

With respect to the refrigerator configured as described above,
The operation will be described below.

First, when the temperature detected by the temperature detector 36 is higher than the set value, the compressor 18 is operated, and the cool air cooled by the cooler 21 is forcibly ventilated by the blower 22 and the cool air discharge port 34 for the freezer compartment. Is discharged into the upper freezer compartment 5 and the lower freezer compartment 6, and then returned to the cooler 21 from the cool air suction port 35. When the temperature detected by the temperature detector 36 becomes lower than the set value, the compressor 18 is stopped, and thereafter, this operation is repeated to cool the room to a freezing temperature of, for example, -18 ° C.

Next, when the detected temperatures of the temperature detectors 36 and 37 are higher than the set value, the cool air cooled by the cooler 21 by opening the damper device 24 is forcibly ventilated by the blower 22 to discharge the first cool air. The air is discharged from the cool air discharge port 28 into the refrigerator compartment 3 through the air passage 27. Then, the cool air that has cooled the inside of the refrigerator compartment 3 flows into the upper surface of the vegetable compartment 4 from the communication port 33, indirectly cools the vegetable compartment from the outer periphery of the storage container 12, and cools through the cool air intake port 32 through the cool air intake air passage 31. Returned to 21. Then, when the temperature detected by the temperature detector 37 becomes lower than the set value, the damper device 24 is closed, and thereafter, this operation is repeated, and the refrigerator compartment 3 is refrigerated at, for example, 4 ° C., and the vegetable compartment 4 is refrigerated at, for example, 6 ° C. Cool to temperature.

When the temperature detected by the temperature detectors 36 and 38 is higher than the set value, the cool air cooled by the cooler 21 by opening the damper device 25 is forcibly ventilated by the blower 22 and the second cool air The air is discharged from the cold air discharge port 30 into the compartment 7 through the passage 29. Then, the cool air that has cooled the inside of the compartment 7 flows into the upper surface of the vegetable room 4 from the communication port 33, indirectly cools the vegetable room from the outer periphery of the storage container 12, and cools through the cool air suction port 32 through the cool air suction air passage 31. Returned to 21. Then, when the temperature detected by the temperature detector 38 becomes lower than the set value, the damper device 25 closes, and thereafter, this operation is repeated, and the inside of the compartment 7 is kept in a temperature zone such as a chilled state of 0 ° C or a partial freezing state of -3 ° C. Cool.

On the other hand, from the viewpoint of the cooling function and the mounting efficiency of the control parts, the cooler 21 serving as a cooling source is set differently from the vegetable compartment 4 having a high internal temperature, so that the upper freezing compartment 5 having the lowest internal temperature is provided. Since it is arranged close to the rear, the temperature inside the vegetable compartment 4 can be reduced, and the upper freezer compartment 5 and the lower freezer compartment 6 can be cooled efficiently. In particular, the upper freezer compartment 5 and the lower freezer compartment 6
Is arranged at the lower part of the refrigerator main body 1, so that the cooler 21 can be inevitably arranged below.
A dead space formed between the cooling device 7 and the cooler 21 can be eliminated.

Furthermore, since the cooler 21 and the blower 22 and the damper devices 24 and 25 disposed on the cooler 21 can be lowered, the mounting efficiency is improved, the inside of the refrigerator can be effectively used, and the refrigerator main body 1 can be used. It is said that the installation can be improved by lowering the center of gravity downward.

Further, the electronic control board 26 for controlling the electric components is not provided on the upper rear surface of the refrigerator body 1 as in the conventional case, but is housed in the air path control panel 23 in the central part of the refrigerator. The compressor 18, the blower 22, the damper devices 24 and 25, the defrost heater 39 mainly arranged below the central portion
Also, there is an advantage that the distance to electric components such as the above is shortened as compared with the related art, and the cost for wiring and the assembly work are reduced.

[0023]

However, in the above-described conventional configuration, the compressor 18 is housed in the machine room 17 extending over the entire width behind the lower freezing room 6, so that the compressor 18 is large in the width direction in the machine room 17. There is a disadvantage that invalid space is generated.

Further, since the cooler 21 is arranged above the compressor 18, if the height of the cooler 18 is designed to have necessary and sufficient cooling capacity, the cooler 1
8 necessarily reaches the height of the heat insulating wall 2. As a result, the blower 22 disposed near the upper portion of the cooler 18 protrudes above the upper freezer compartment 5, so that the rear end portion of the heat insulating wall 2 is partially raised to raise the rising portion 2.
It is necessary to form a and to insulate the surroundings of the blower 22 and the vegetable compartment 4 from each other, resulting in a disadvantage that the structure becomes complicated and the ineffective volume increases.

Further, since the rising section 2a of the heat insulating wall, the blower 22, and the air path control panel 23 are arranged at the rear, the depth of the vegetable compartment 4 and the compartment 7 is violated, and the storage amount is reduced, and the height of the refrigerator is reduced. There is also a drawback that the storage ability of the storage portion, which is located almost at the center and is most convenient for the storage operation, is hindered.

Further, since the condenser 19 and the evaporating dish 20 are vertically arranged in the machine room 17 which is the bottom of the refrigerator main body 1, a certain height is secured in order to secure the heat radiation capacity of the condenser 19 and the evaporating capacity of the evaporating dish. Space is needed. For this reason, there was also a disadvantage that the space in the storage room was violated and the volumetric efficiency was reduced.

Further, although the electronic control board 26 is improved over the conventional one which is arranged on the rear upper part of the refrigerator,
It was still away from the compressor 18 and the defrost heater 39, etc., and the effect of shortening the electric wiring was not sufficient.

On the other hand, each of the refrigerator compartment 3, the vegetable compartment 4, the upper freezer compartment 5, the lower freezer compartment 6, and the compartment 7 is provided with one cooler 18
And the cooling by the blower 22, there is a drawback that the storage condition of the stored food is deteriorated due to the mutual influence of the temperature condition in each use condition.

The evaporating temperature of the cooler 18 is designed based on the freezing room having the lowest room temperature. For this reason, the design of the evaporating temperature is not optimal for each of the refrigerator compartment 3, the vegetable compartment 4, and the compartment 7 where the indoor set temperature is higher than that of the freezing compartment.

For this reason, the room is cooled by low-temperature cold air that has been heat-exchanged at an unnecessarily low evaporation temperature, which promotes drying of the food being stored and the temperature caused by partial supercooling. There is a drawback that unevenness may occur and affect the storage quality of food.

The desired cooling can be achieved by lowering the efficiency of the refrigeration cycle due to the design of the evaporating temperature being lowered unnecessarily, and increasing the power of the blower by forcibly ventilating all the rooms by one blower 22. There is a disadvantage that power consumption for maintaining the state is increased.

The first object of the present invention is to solve the above-mentioned conventional problems, and a first object of the present invention is to provide a refrigerator in which the mounting efficiency of a cooling function component and a cooling control component is increased and the internal volume efficiency is increased.

[0033] A second object of the present invention is to provide a refrigerator having improved storability in an easy-to-use area located at the center of the height of the refrigerator.

[0034] A third object of the present invention is to provide a refrigerator capable of improving the storage quality of food and saving energy.

[0035]

In order to achieve the above object, the present invention provides a storage device provided in two or more storage rooms including a lowermost storage room among a plurality of storage rooms provided vertically in a refrigerator main body. And a compressor provided in a machine room formed behind a lowermost storage room.

[0036] Thus, it is possible to provide a refrigerator in which the mounting efficiency of the refrigeration cycle, which is a cooling function component, is increased, and the internal volume efficiency is increased. In addition, the cooling efficiency and the independence of the cooling are increased, so that the storage quality of the food can be improved and energy can be saved.

According to the present invention, a refrigerator compartment is formed at the upper part of a heat insulating wall which partitions the refrigerator body into upper and lower parts, and a freezer compartment is formed at the lower part. The first cooler, the first blower and the upper part of the refrigerator compartment are formed inside the refrigerator compartment. , A second cooler and a second blower are provided, and a compressor and a first cooler provided in a machine room formed in a lower rear portion of the refrigerator main body are arranged side by side in the left-right direction.

A second refrigerant circuit 87 that connects the coolers 58 in a ring is formed.

With respect to the refrigerator configured as described above,
The operation will be described below.

First, when the temperature detected by the temperature detector 81 in the freezer compartment is higher than the set value, the compressor 57 operates. At this time, if the temperature detected by the temperature detector 82 in the refrigerator compartment is higher than the set value, the switching valve 83 opens, and the refrigerant flows into the first refrigerant circuit 86.
And evaporates at a predetermined evaporating temperature in the first cooler 58 and the second cooler 65, respectively.

Then, the cool air cooled by the first cooler 58 designed to have a low evaporation temperature is forcibly ventilated by the first blower 59 and is discharged from the cool air discharge port 69 to the freezing chamber 46. It is returned to the cooler 58 through the port 70.

On the other hand, the cool air cooled by the second cooler 65 designed to have a relatively high evaporation temperature is forcibly ventilated by the second blower 66, and is passed through the cool air discharge air passage 76 from the cool air discharge port 77 to the refrigerator compartment 44. Is discharged. A part of the cold air introduced into the refrigerator compartment 44 is supplied to the cold air inlet 75 at the rear of the refrigerator compartment.

Into the vegetable compartment 45, convection around the storage container 52, and from the communication port 73 at the rear of the partition plate 71 to the cold air suction air passage 7.
4 and is returned to the second cooler 65.

Next, when the temperature detected by the temperature detector 82 in the refrigerator compartment 44 becomes lower than the set value, the switching valve 83 closes, and the refrigerant bypasses the first refrigerant circuit 86 and passes through the second refrigerant circuit 87. And evaporates only in the first cooler 58. Then, when the temperature detected by the temperature detector 81 in the freezer compartment 46 becomes lower than the set value, the compressor 57 stops, and the circulation of the refrigerant also stops.

Thereafter, the above operation is repeated, and the inside of the freezing chamber 46 is kept cooled to the freezing temperature of, for example, -18 ° C. by the cool air having the low evaporation temperature of the first cooler 58. On the other hand, the inside of the refrigerator compartment 44, the vegetable compartment 45, and the compartment 48 is cooled by the second cooler 65 having a relatively high evaporation temperature.
For example, the refrigerating room 44 and the compartment 48 are kept at an appropriate temperature of 1 to 3 ° C., and the vegetable room 45 is kept at an appropriate temperature of 3 to 5 ° C.

As described above, the low-temperature freezing compartment 46 and the other compartments having a high temperature setting are provided with the exclusive coolers 58 and 65, respectively.
And the blowers 56 and 66 for independent cooling.
The mutual temperature effect between the chamber 6 and the other chambers is suppressed. That is, in practical use, the influence of temperature rise such as opening and closing of the door, storage of food, defrosting of the cooler, etc. is less likely to occur, and deterioration of the quality of food during storage can be suppressed.

In particular, in the freezing room 46 in which temperature control is more strictly required than in the past, the temperature effect is relatively large in a relatively high temperature region such as the refrigerating room 44. In addition, because of the invasion of external moisture from those chambers having large capacity and the evaporation of moisture from food, the cooling power is greatly reduced due to frost formation on the cooler 58 and the temperature rise during defrosting is large. Quality can be maintained.

The evaporating temperature of the second cooler 65 for cooling these areas of the refrigerating room 44, the vegetable room 45, and the compartment room 48 having a high temperature setting is adjusted to the evaporating temperature of the first cooler 58. It can be designed at a relatively high temperature that matches the internal temperature setting without the need. For this reason, the temperature of the cold air flowing through each chamber is also relatively high, and the temperature difference between the food and the cold air is reduced, and the evaporation of water from the food can be suppressed to suppress the drying. Therefore, the storage quality can be particularly improved in the storage of fresh food or the like, which has a large amount of water and whose freshness and dryness affect freshness and quality. Further, since the cold air temperature is not too low, unevenness in the temperature of the stored food, such as local overcooling due to contact with the cold air, hardly occurs, and the storage quality can be improved in this aspect as well.

Further, the first cooler 58 and the second cooler 6
5 is appropriately switched when necessary, and the evaporating temperature of the cooler is designed to be suitable for each region. In particular, the efficiency of the refrigeration cycle is designed by setting the evaporating temperature of the second cooler to be relatively high. And an energy saving effect can be obtained.

On the other hand, regarding the arrangement of the refrigeration cycle, the compressor 57 is shifted laterally from the center line of the refrigerator body 42 to compress the ineffective space in the machine room 56 and
It is reduced to almost half the width of 2. The first cooler 58 is accommodated in a newly created space inside the refrigerator by reducing the ineffective space while adjusting the depth and height dimensions to maintain the cooling capacity.

For this reason, the compressor 57 and the first cooler 58
Are arranged side by side in the left-right direction via the heat insulating wall 42a, so that there is no need to arrange a cooler above the compressor as in the related art to create an ineffective space in the width direction of the refrigerator,
The effective storage volume in the storage increases.

Further, by arranging the heavy compressor 57 and the first cooler 58 side by side in the left-right direction, the center of gravity of the refrigerator main body 42 becomes lower than the conventional one, and the stability is further increased.

The compressor 57, the first cooler 58, the first
Are arranged efficiently behind the freezer compartment 46 located at the bottom of the refrigerator main body 42, and the mounting efficiency is increased. Therefore, the assembling workability in the manufacturing process is improved. In addition, it is possible to adapt to environmental problems by providing a refrigerator that is easy to recycle by improving the disassembling and sorting properties at the time of product disposal.

Further, the first blower 59 is provided with the first cooler 5.
By arranging it just above and at an angle to the obliquely upward direction, the dimension in the height direction can be compressed, and it becomes easier to fit the rear of the freezing compartment 46 in the projection plane. In addition, due to the inclined arrangement, the blowing resistance for sending the cool air from the first coolers 58 arranged in the vertical direction into the freezer compartment 46 at the front is reduced, and the cooling efficiency is increased. It should be noted that most of the components such as the compressor 57, the first cooler 58, and the first blower 59 fit within the projection plane of the opening of the freezing compartment 46 and protrude into the other compartments. It does not deviate from the gist of the present invention that part of the components interferes with the thickness of the heat insulating wall that partitions the periphery of the freezer compartment 46 or the projection surface of the bottom space of the main body.

Further, while the first blower 59 is arranged above the first cooler 58, it does not violate the space behind the vegetable compartment 45, and the second cooler 65 and the second blower 66 are refrigerated. Vegetable room 4 because it is located in the upper rear part of room 44
5. Vegetable room 4 so as not to infringe the space behind compartment 48
The storage container 52 of No. 5 and the storage container 49 of the compartment 48 can be extended in depth to a position facing the heat insulating wall 42b on the back surface, and the storage amount can be increased. In addition, by replacing the increase in storage capacity with a decrease in height,
In particular, the vegetable room 45 is a shallow and wide vegetable room, and it is possible to realize a vegetable room that is easy to overlook, has little storage, and has good storage and preservation.

Further, the first blower 5
Because there is no need to construct a space for storing
The heat insulating wall 43 between the freezer compartment 46 and the freezer compartment 46 does not need to be raised at the rear thereof as in the conventional case, so that the ineffective volume is reduced and the effective storage volume is increased. Further, since the vegetable room 45 is provided with an independent drawer-type door 51, the depth of the room is not short, unlike the case where the vegetable room is partitioned in the refrigerator room 44, and the vegetables are shallow and easy to see. Room is easy to realize. In addition, food can be taken in and out independently and convenience is high. With these features, it is possible to provide a refrigerator with improved storability in an easy-to-use area located at the center of the height of the refrigerator.

Next, the operation in the machine room 57 will be described. By the operation of the forced air blower 64, the air sucked in from the front and the bottom of the refrigerator exchanges heat with the condenser 60 to promote heat dissipation and pass through the upper surface of the evaporating dish 62. Evaporating dish 6
Defrost water stored in the condenser pipe 6 is immersed in the condenser pipe 6
At the same time as being heated by the direct heating action of Oa, the heating and ventilation are promoted by the forced convection of the hot air that has been heat-exchanged with the condenser 60, so that the vapor is efficiently evaporated. The air that has passed through the evaporating dish 62 cools the outer shell of the compressor 57 having a higher temperature, and is then exhausted from the front of the refrigerator.

During the cooling, the first cooler 58 and the second cooler 58
Adhered to the cooler 65 of the first defrost heater 61,
It is melted by the second defrost heater 67 and collected in the evaporating dish 62 via the first drain pipe 63 and the second drain pipe 68. Therefore, the waste water from the two coolers can be evaporated by one evaporating dish, and in particular, the first drain pipe 6
3 has a vertical relationship close to the first cooler 58, so that the length of the drain pipe can be shortened and a simple configuration can be achieved. In addition,
Since the evaporating dish 62 is disposed in a stepped space where the compressor 57 and the first cooler 58 are juxtaposed in a stepwise manner in the height direction, the space can be efficiently used, and the inner volume efficiency can be increased. .

Next, since the electronic control board 78 for driving and controlling the electric components is housed outside the refrigerator behind the first cooler 58, the compressor 57, the first blower 59, and the blower 6
4. The electric wiring is short and simple because it is close to the electric components such as the first defrost heater 61, so that the cost can be reduced and the number of working steps can be reduced. Also, the complicated routing of electrical wiring is reduced,
It is possible to provide a highly reliable refrigerator in which the influence of radio noise interference is reduced.

The volume generated by the improvement of the mounting efficiency of the cooling function component and the cooling control component is directly used for increasing the storage volume, and the internal volume is kept unchanged to reduce the outer shape of the refrigerator main body 42 to reduce the installation space. Alternatively, the heat absorption load of the refrigerator may be reduced by transferring the increased volume to the adiabatic volume, thereby contributing to energy saving and cost reduction by downsizing the refrigeration cycle components such as the compressor 57.
