Description

refrigerator

This disclosure relates to a refrigerator suitable for being used in a built-in system kitchen or the like.

Generally, in a refrigerator, a cooling fan is provided in a machine room disposed at the bottom of the main body together with a compressor and a condenser. The compressor, the condenser, and the like arranged in the machine room are cooled by air sucked and exhausted from the front of the machine room. However, an undercounter type refrigerator built in a system kitchen or the like is completely covered with no gaps on both sides of the machine room and the rear part, so the cooling fan can be used as efficiently as possible. Need to be cooled.

A refrigerator that cools a compressor, a condenser, and the like in a machine room by air sucked and exhausted from the front part of the machine room is partitioned into a compressor side and a condenser side by a partition plate, and the machine room is It is comprised so that it may cool (for example, refer to patent documents 1).

FIG. 12 is a plan view of a machine room of a conventional refrigerator. Although the refrigerator 111 described in Patent Document 1 shown in FIG. 12 is not an undercounter type refrigerator, the inside of the machine room 100 is divided into a condenser room 102 and a compressor room 103 by a partition plate 101. In the refrigerator 111, the condenser 104 and the evaporating dish 105 are incorporated in the condenser chamber 102, and the compressor 106 is incorporated in the compressor chamber 103. A cooling fan 107 is provided on the partition plate 101.

With the configuration as described above, in the refrigerator 111, air is sucked by the cooling fan 107 from the air suction port portion 108 provided on the front surface of the machine room 100 on the condenser room 102 side. The sucked air cools the condenser 104 in the condenser chamber 102 and cools the compressor 106 in the compressor chamber 103. Further, the sucked air is exhausted from an air discharge port portion 109 provided on the front surface of the machine chamber 100 on the compressor chamber 103 side.

In the refrigerator 111 described in Patent Document 1, since the inside of the machine room 100 is partitioned into a condenser room 102 and a compressor room 103 by a partition plate 101, the air taken in by the cooling fan 107 is taken from the condenser room 102. The air can be circulated in an orderly manner to the compressor chamber 103, and the condenser 104 and the compressor 106 can be efficiently cooled.

However, since the inside of the machine room 100 is partitioned into a condenser chamber 102 and a compressor chamber 103 by a partition plate 101, the condenser chamber 102 and the compressor chamber 103 that are divided into left and right by the partition plate 101 are the condenser 104. And the dimension for each to install the compressor 106 is required. For this reason, there is a problem that it is too large to be applied as an undercounter type refrigerator built in and used in a system kitchen or the like.

Moreover, the refrigerator 111 described in Patent Document 1 is provided with an evaporating dish 105 behind the condenser 104 and on the side of the compressor 106. That is, since the evaporating dish 105 is also disposed on the upstream side of the cooling fan 107 together with the condenser 104, the air sucked by the cooling fan 107 receives resistance from the evaporating dish 105 in addition to the condenser 104. Become. Therefore, the air sucked by the cooling fan 107 is subjected to resistance by the condenser 104 and the evaporating dish 105, so that the amount of air flowing to the compressor 106 is reduced and the air flow is weak. For this reason, the temperature of the atmosphere in the machine room 100 tends to be increased by the heat dissipated from the compressor 106, and there is a problem in improving the cooling efficiency of the compressor 106. Moreover, when the temperature of the atmosphere in the machine room 100 becomes high, the heat insulation wall thickness of the bottom part of the main body of the refrigerator 111 must be increased, and there is a problem of affecting the storage room capacity.

Furthermore, as described above, the condenser chamber 102 requires dimensions for installing the condenser 104 and the evaporating dish 105, and the compressor chamber 103 requires dimensions for installing the compressor 106. For this reason, it is difficult to make the horizontal width of the machine room 100 (the width in the left-right direction when the refrigerator 111 is viewed from the front) at least equal to or less than the total size of the horizontal widths of the compressor 103 and the evaporating dish 105 arranged in the width direction. It becomes. For this reason, there also exists a subject that it is difficult to obtain small refrigerators, such as 15-inch width required when built in a system kitchen etc.

Furthermore, a wind tunnel part has a rear surface wall which divides a compressor and a condenser between a compressor and a condenser. The cooling fan is provided on the rear wall of the wind tunnel and is arranged to blow air toward the compressor.

With such a configuration, the air sucked from the air suction port on the front side of the machine room flows in the wind tunnel and cools the condenser, and is then blown to the compressor to cool the compressor and is surrounded by the wind tunnel. It flows through the remaining space of the machine room other than the part that is exhausted, and is exhausted from the air discharge port on the front surface of the machine room.

The machine room 15 is provided with a cooling fan 18 as shown in FIG. An air suction port 19 is provided on the left side of the machine room 15, for example, on the front side. Air is sucked from the air suction port portion 19, and the condenser 17 and the compressor 16 are cooled by the air sucked from the air suction port portion 19. The air sucked from the air suction port portion 19 further cools the main body control device 20 provided at the corner portion of the machine room 15, and from the air discharge port portion 21 provided at the front right side of the machine room 15, It exhausts toward the front of the machine room 15.

4 to 7, a front plate decoration 51 is provided on the front portion of the machine room 15, and the front plate decoration 51 is formed with a slit-like air suction port portion 19 and an air discharge port portion 21. . The back of the machine room 15 is closed with a cover plate 52 attached. Further, in the machine room 15, a container 53 a having an air suction port 19 side opened at a portion facing the air suction port part 19 has a longitudinal direction in the longitudinal direction of the machine room 15 in the machine room 15. Arranged to form a wind tunnel 53. The condenser 17 is installed in the wind tunnel 53.

As shown in FIG. 7, the container 53 a that forms the wind tunnel portion 53 is formed in a substantially square box shape so as to surround the condenser 17. The container 53 a includes a side wall 53 b and a rear wall 53 c that are higher than the height of the condenser 17, and is configured to partition the condenser 17 from other space portions in the machine room 15.

Further, as shown in FIG. 6, in the width direction of the machine room 15 (left and right direction when the refrigerator 50 is viewed from the front side), the condenser 17 and the compressor are located behind the wind tunnel portion 53 formed by the container 53a. 16 are arranged so that a part of the lateral width overlaps (L portion in FIG. 6). That is, the condenser 17 and the compressor 16 are arranged side by side in the machine room 15 side by side, and are arranged behind the condenser 17 when the inside of the machine room 15 is viewed from the front of the refrigerator 50 in the horizontal direction. Further, a part of the width of the condenser 17 and the compressor 16 are overlapped so that a part of the compressor 16 is not visible by the condenser 17.

Furthermore, an evaporating dish 54 is installed on the top of the compressor 16 (see FIGS. 2 to 4). A cooling fan 18 is disposed between the condenser 17 and the compressor 16. More specifically, the cooling fan 18 is provided on a portion that partitions between the condenser 17 and the compressor 16, that is, the rear wall 53c of the container 53a.

Further, as shown in FIG. 7, at least a part of the rear wall 53c of the container 53a in which the cooling fan 18 is installed has an inclination 53d. Specifically, the slope 53d is formed so that the wall thickness of the portion of the rear wall 53 farthest from the compressor 16 is thick so that the blower side surface of the cooling fan 18 faces the compressor 16 as much as possible. It is formed by thinning the wall thickness of the portion closest to the compressor 16 of the above. By mounting the cooling fan 18 on the rear wall 53c having the inclination 53d, the cooling fan 18 is installed in an inclined state with respect to the compressor 16 (see FIG. 6). Furthermore, the cooling fan 18 is arranged so that the blowout side is located on the compressor 16 side, and is arranged so as to blow air toward the compressor 16.

Further, as shown in FIG. 6, a main body control device 20 that controls the compressor 16 and the cooling fan 18 is incorporated in the rear corner portion of the space 55 on the downstream side of the compressor 16. The space 55 is configured as a simple space in which the evaporating dish 54 or the like does not exist, and the lower portion of the space 55 is in an open state.

In addition, the refrigerator 50 is configured such that a wind tunnel portion 53 is formed and the inside of the machine room 15 is partitioned by providing the container 53a. With such a configuration, the lower surface of the machine room 15 of the main body 1 does not need to be provided with a bottom plate, and is open as shown in FIG.

In the refrigerator 50 of the present embodiment, the lower surface of the machine room 15 of the main body 1 is reinforced by the front reinforcing beam 56 and the rear reinforcing beam 57. Further, the container 53 a constituting the wind tunnel portion 53 is fixed to the front reinforcing beam 56 and the rear reinforcing beam 57. The compressor 16 is mounted and fixed on the rear reinforcing beam 57.

Next, in the refrigerator 50 configured as described above, the effects of cooling the condenser 17 and the compressor 16 in the machine room 15 will be described.

When the compressor 16 is driven to cool one or both of the

storage chambers

3 and 4, the cooling fan 18 rotates and air is sucked from the air suction port 19 on the front surface of the machine chamber 15. . The sucked air flows through the wind tunnel portion 53 disposed opposite to the air suction port portion 19, and cools the condenser 17 installed in the wind tunnel portion 53. The cold air after cooling the condenser 17 is sucked into the cooling fan 18 and blown toward the compressor 16 to cool the compressor 16. The cold air after cooling the compressor 16 flows toward the main body control device 20 provided in the rear corner portion of the space 55 downstream of the compressor 16, cools the main body control device 20, and then passes through the space 55. It is discharged from the air discharge port 21 on the front surface of the machine room 15.

Here, as described above, the wind tunnel portion 53 is configured by providing the substantially square box-shaped container 53a surrounding the condenser 17, and the side wall 53b and the rear wall 53c higher than the height of the condenser 17 are provided. I have. The wind tunnel 53 is configured to partition the condenser 17 from other parts in the machine room 15. With such a configuration, the air sucked from the air suction port portion 19 flows in an orderly manner in the machine chamber 15 as indicated by arrows in FIG. 6, and cools the condenser 17, the compressor 16 and the main body control device 20. To go. Therefore, with such a configuration, the condenser 17, the compressor 16, and the main body control device 20 can be efficiently cooled.

Further, the refrigerator 50 according to the present embodiment is configured such that only the condenser 17 is arranged on the upstream side of the cooling fan 18 of cool air flowing in the machine room 15. With such a configuration, unlike the cooling fan in the conventional refrigerator, the cooling fan 18 does not receive resistance due to the evaporating dish. Accordingly, a larger amount of air can be sucked by the cooling fan 18, and the air blown from the cooling fan 18 to the compressor 16 has a large amount and a strong flow, so that the compressor 16 can be cooled strongly.

Thereby, the temperature of the compressor 16 can be greatly reduced, the temperature of the machine room 15 is also lowered, the wall thickness of the heat insulation wall at the bottom of the main body 1 is reduced, and the storage chamber 4 disposed below the main body 1. Capacity can be increased. For example, as shown by a broken line in FIG. 2, the space below the shelf 5 of the storage chamber 4 disposed on the lower side of the main body 1 can be increased. You will be able to do things like this, and it will be easier to use.

On the other hand, as described above, the condenser 17 and the compressor 16 are arranged such that a part of the lateral width overlaps (L portion in FIG. 6) in the width direction of the machine room 15 as shown in FIG. 6. ing. Further, the evaporating dish 54 is installed on the upper portion of the compressor 16. With such a configuration, the width of the machine room 15 can be reduced by an amount corresponding to the overlap of the condenser 17 and the compressor 16. That is, in this case, the machine room 15 does not require a width dimension obtained by adding the width of the condenser 17 and the width of the compressor 16, and the width of the machine room 15 can be shortened. Can be reduced in size.

Furthermore, a space 55 from the compressor 16 to the air discharge port 21 on the front surface of the machine room 15 is a space where the evaporating dish 54 or the like does not exist. With such a configuration, the condenser 17 and the compressor 16 are adjusted by increasing / decreasing the width dimension of the space 55 in a state where a part of each lateral width is overlapped in the width direction of the machine room 15. By doing so, it is possible to provide the main body 1 having the machine rooms 15 of several types having different widths, that is, the refrigerator 50 having different widths of different sizes. For example, it is possible to easily change the design so as to have a width of 15 inches or 13 inches, which is a standard for the built-in width of the system kitchen.

At the same time, the space 55 from the compressor 16 to the air discharge port 21 on the front surface of the machine room 15 can be an exhaust path having no evaporating dish 54 or the like and having a small ventilation resistance. With such a configuration, the flow of the cooling air in the machine room 15 can be smoothed, and more efficient cooling is possible.

Further, the cooling fan 18 of the present embodiment is installed to be inclined toward the compressor 16. With such a configuration, the air sent from the cooling fan 18 is blown directly toward the compressor 16. Thereby, compared with the case where the air sent from the cooling fan 18 collides with the rear wall of the machine room 15 and changes its direction and is blown to the compressor 16, the flow velocity of the air blown to the compressor 16 becomes faster. The compressor 16 can be cooled more efficiently, and the temperature of the machine room 15 can be lowered.

Furthermore, a main body controller 20 that controls the operation of the compressor 16 and the like is installed in a space 55 on the downstream side of the compressor 16. With such a configuration, the main body control device 20 can also be cooled by the air after cooling the compressor 16. Therefore, even when an inverter-type control device that tends to become high temperature is used for the main body control device 20, the main body control device 20 can be efficiently cooled.

As described above, according to the present embodiment, the temperature reduction of the machine room 15 is promoted while the fine cooling control of the

storage rooms

3 and 4 is realized, and a larger storage room volume of the refrigerator 50 can be secured. .

In addition, the condenser 17 and the cooling fan 18 of the refrigerator 50 according to the present embodiment may be unitized in a container 53a constituting the wind tunnel portion 53, or may be integrated. With such a configuration, the condenser 17 and the cooling fan 18 can be incorporated into the machine room 15 only by incorporating the container 53 a into the machine room 15.
