JP-A-2019-132506

By arranging the evaporating dish on the upper part of the compressor, it becomes difficult for the heat generated by the compressor to escape upward. Therefore, the hot air tends to spread to the side of the compressor in the machine room, and the temperatures on both the left and right sides of the machine room rise. Placing precision parts such as a control board in a machine room in such a high temperature environment is not desirable because it may cause a failure or the like.

Therefore, an object of the present invention is to provide a refrigerator capable of easily releasing heat generated by a compressor in a machine room.

The refrigerator according to one aspect of the present invention is located above the refrigerating cycle including the compressor and the evaporator, the machine room in which the compressor is arranged, and the compressor, and the condensed water generated in the evaporator. It is equipped with an evaporating dish to be discharged. In this refrigerator, a recess along the shape of the head of the compressor is provided on the bottom surface of the evaporating dish, and a groove for exhaust heat is provided on at least one side wall from the bottom surface on the outside of the evaporating dish. Is formed, one end of the groove is continuous with the recess, and the other end of the groove extends to the upper end of the side wall.

According to one aspect of the present invention, it is possible to provide a refrigerator capable of easily dissipating heat generated by a compressor in a machine room.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same parts are designated by the same reference numerals. Their names and functions are the same. Therefore, the detailed description of them will not be repeated.

<First Embodiment>
(Overall configuration of refrigerator)
First, the overall configuration of the refrigerator 1 according to the first embodiment will be described. FIG. 1 shows the configuration of the back side of the refrigerator 1. Further, FIG. 2 shows the internal configuration of the refrigerator 1. In FIG. 2, the components in the machine room 30 other than the compressor 31 are not shown.

As shown in FIG. 2, the refrigerator 1 includes a first refrigerating chamber 11 in the upper stage, a freezing chamber 12 in the middle stage, a second refrigerating chamber 13 in the lower stage, and the like. The first refrigerating room 11 is provided with a refrigerating room door 11a. The freezing room 12 is provided with a freezing room door 12a. The second refrigerating room 13 is provided with a refrigerating room door 13a.

As described above, the refrigerator 1 according to the present embodiment is divided into an upper part, a middle part, and a lower part, and each storage space is provided. A partition 59 is provided between the storage spaces. However, the arrangement position of each storage space is not limited to this.

In the present embodiment, the surface provided with the door is referred to as the front surface or the front surface of the refrigerator. Then, with reference to the front surface, each surface of the refrigerator 1 is defined as an upper surface, a side surface, a back surface, and a bottom surface based on the positions existing when the refrigerator 1 is installed in a normal state.

A refrigeration cycle 40 is provided inside the refrigerator 1. In the refrigeration cycle 40, the compressor 31, the condenser (not shown), the expander (not shown), and the cooler (evaporator) 32 pass through the refrigerant pipe (refrigerant flow path) through which the refrigerant flows. It is connected and configured.

As shown in FIG. 2, the compressor 31 is arranged in a machine room 30 provided on the back side of the bottom of the refrigerator 1. The cooler 32 is arranged in a cooling chamber 35 provided on the back side of the refrigerator 1. In addition to the cooler 32, a cooling fan 33 and the like are provided in the cooling chamber 35. The cooling fan 33 is provided to circulate air between the cooling chamber 35 and each storage space.

Further, a control unit is provided inside the refrigerator 1. The control unit is arranged, for example, on the control board 21 described later. This control unit controls the operation of the refrigeration cycle 40. That is, when the control unit drives the compressor 31, the operation of the refrigeration cycle is started, and the refrigerant flows in the cycle.

Specifically, the high-temperature and high-pressure refrigerant compressed by the compressor 31 is condensed while dissipating heat in the condenser. Subsequently, the high-pressure refrigerant expands in the expander to become a low-temperature low-pressure, and is sent to the cooler 32 as an evaporator. The refrigerant flowing into the cooler 32 exchanges heat with the cold air flowing in the cooling chamber 35, evaporates while absorbing heat, becomes a low-temperature gas refrigerant, and is sent to the compressor 31. In this way, the refrigerant circulates to operate the refrigeration cycle, and cold air is generated by the air flow that exchanges heat with the cooler 32.

(Structure of heat insulating box)
The refrigerator 1 is provided with a heat insulating box 50 as a heat insulating structure for insulating each storage space from the surroundings. The heat insulating box body 50 is provided so as to cover the outer periphery of the refrigerator 1. As shown in FIG. 2, the heat insulating box body 50 mainly includes an outer box 61, an inner box 62, a vacuum heat insulating material 51, and a foam heat insulating material 56.

The outer box 61 forms the outer peripheral surface of the heat insulating box body 50. The outer box 61 is mainly composed of an upper surface portion 50a, a side surface portion 50b, a back surface portion 50c, and a bottom surface portion 50d. The inner box 62 forms the inner peripheral surface of the heat insulating box body 50. Further, the inner box 62 forms a boundary between the storage space (for example, the first refrigerating chamber 11, the freezing chamber 12, the second refrigerating chamber 13) and the cooling chamber 35.

A space for arranging the machine room 30 is formed on the back side of the bottom of the heat insulating box 50. That is, the machine room 30 is arranged outside the heat insulating box 50. This is because the temperature inside the machine room 30 rises as the compressor 31 is operated.

The vacuum heat insulating material 51 and the foam heat insulating material 56 are provided in the space between the outer box 61 and the inner box 62. The vacuum heat insulating material 51 is a thin sheet-shaped or plate-shaped heat insulating material. The vacuum heat insulating material 51 is arranged, for example, on the side surface, the upper surface, the bottom surface, the back surface, and the like of the refrigerator 1. The foamed heat insulating material 56 can be formed of, for example, foamed polyurethane (also referred to as rigid urethane foam).

(Composition inside the machine room)
Subsequently, a more detailed configuration of the machine room 30 provided below the back surface side of the heat insulating box 50 will be described with reference to FIG. 1 and the like. FIG. 1 shows the back surface portion of the heat insulating box body 50 in a state where the back cover covering the back surface of the machine room 30 is removed. FIG. 3 shows a state in which the substrate unit 20 arranged in the machine room 30 is removed in the refrigerator 1 shown in FIG. FIG. 4 schematically shows the positional relationship of each component (that is, the compressor 31, the substrate unit 20, and the evaporating dish 70) arranged in the machine room 30.

The back surface portion 50c of the heat insulating box body 50 is mainly composed of the back plate of the outer box 61. The machine room 30 is located below the back surface portion 50c. The machine room 30 is mainly partitioned by a bottom plate 63 forming a bottom surface portion 50d of the heat insulating box body 50. As shown in FIG. 2 and the like, the rear portion of the bottom plate 63 is raised upward. The rearmost side of the bottom plate 63 has a substantially flat shape in the horizontal direction, and this portion forms the ceiling portion 63a of the machine room 30.

The bottom plate 63 has a ceiling portion 63a and a rising portion 63c as regions for partitioning the machine room 30 (see FIG. 2). The ceiling portion 63a forms the upper surface (ceiling) of the machine room 30. The rising portion 63c forms the front surface of the machine room 30. Further, the side surface of the machine room 30 is formed by the side surface portion 50b of the outer box 61.

A compressor 31, a substrate unit 20, an evaporating dish 70, and the like are mainly arranged in the machine room 30. The compressor 31 is arranged on the slightly right side (left side when viewed from the front) in the machine room 30 when viewed from the back. The substrate unit 20 is arranged next to the compressor 31. In the example shown in FIG. 1, the substrate unit 20 is arranged on the left side of the compressor 31 (on the right side of the compressor 31 when viewed from the front). However, in another example, the substrate unit 20 may be arranged on the right side of the compressor 31 (on the left side of the compressor 31 when viewed from the front).

A control board 21 is arranged in the board unit 20. As shown in FIG. 4, the control board 21 is arranged in the vertical direction (direction orthogonal to the horizontal plane). More specifically, the control board 21 is arranged substantially parallel to the side surface portion 50b of the heat insulating box body 50 forming the side wall of the machine room 30.

Further, in the machine room 30, a harness 38 including various wirings is arranged on the front side of the space 20A in which the substrate unit 20 is arranged (see FIG. 3). The harness 38 is connected to each electric component in the heat insulating box 50, each electric component in the machine room 30 such as the compressor 31, a control board 21, a power supply unit (not shown), and the like.

The evaporating dish 70 is arranged above the compressor 31. Condensed water (also called drain water) generated in the cooling chamber 35 is discharged to the evaporating dish 70. The condensed water generated in the cooling chamber 35 includes, for example, defrosted water generated when the cooler 32 is defrosted. As shown in FIG. 4, an upwardly curved recess 71 is formed in the bottom surface 70d of the evaporating dish 70. The recess 71 is molded into a shape that follows the shape of the upper portion (head) of the compressor 31.

(Composition of evaporating dish)
Subsequently, a more detailed configuration of the evaporating dish 70 will be described. 5, 6, and 7 show the configuration of the evaporating dish 70. FIG. 5 is a perspective view of the evaporating dish 70 when viewed from above on the back side. FIG. 6 is a perspective view of the evaporating dish 70 when viewed from above on the front side. FIG. 7 is a perspective view of the evaporating dish 70 when viewed from below on the back side.

The evaporating dish 70 generally has a rectangular parallelepiped box shape. The upper part of the evaporating dish 70 is open. The outer shape of the evaporating dish 70 is mainly composed of a front surface portion 70a, side surface portions 70b / 70b on both left and right sides, a back surface portion 70c, and a bottom surface portion 70d. The name of each surface portion is defined based on the position of the evaporating dish 70 when it is attached to the refrigerator 1. By having each of these surface portions, it is possible to store the drain water discharged from the drain pipe 43 (see FIG. 8) arranged above.

The front surface portion 70a, the side surface portions 70b and 70b on both the left and right sides, and the back surface portion 70c form a side wall of the evaporating dish 70.

The bottom surface 70d of the evaporating dish 70 is provided with a recess 71 that follows the shape of the head of the compressor 31. For example, the recess 71 has a shape in which an elliptical flat surface is raised in a dome shape (see FIG. 7). On the outer surface side of the evaporating dish 70, a groove 72 for exhausting heat for exhausting the heat generated by the compressor 31 is provided. The groove 72 is formed from the bottom surface portion 70d to the back surface portion 70c. That is, the end portion of the groove 72b formed in the bottom surface portion 70d is continuous with the recess 71. Further, the end portion of the groove 72a formed in the back surface portion 70c extends to the upper end of the back surface portion 70c.

As described above, the evaporating dish 70 is formed with a groove 72 that extends continuously from the recess 71 adjacent to the head of the compressor 31 to the back surface 70c. As a result, the heat generated by the compressor 31 can be guided to the back surface 70c side of the evaporating dish 70 through the groove 72.

A support portion 73 extending upward is provided on the back surface portion 70c of the evaporating dish 70. The number of support portions 73 is not particularly limited, but in the present embodiment, two support portions 73 are provided. As shown in FIG. 3, the upper end portion of the support portion 73 is supported and fixed to the back surface portion 50c of the heat insulating box body 50.

The inside of the evaporating dish 70 is divided into a plurality of regions by some partition walls (for example, the first partition wall 74 and the second partition wall 75) erected from the bottom surface portion 70d.

Specifically, the first partition wall 74 partitions the first water storage area 74A. The first partition wall 74 is provided on the recess 71. That is, the first partition wall 74 is provided slightly inside the outer periphery of the recess 71 so as to follow the shape of the recess 71. Further, a part 74a of the first partition wall 74 located on the back surface portion 70c side extends linearly substantially parallel to the back surface portion 70c. As a result, a region surrounded by the first partition wall 74 is formed.

A drain pipe (drainage pipe) 43 is arranged above the area partitioned by the first partition wall 74. FIG. 8 shows the positional relationship between the drain pipe 43 and the evaporating dish 70. The drain pipe 43 extends from the inside of the cooling chamber 35 to the machine chamber 30. The drain pipe 43 is provided so as to penetrate the foamed heat insulating material 56 between the cooling chamber 35 and the machine chamber 30.

As shown in FIG. 8, an evaporating dish 70 is arranged below the drain pipe 43. The drain water generated in the cooling chamber 35 during the defrosting operation or the like is discharged to the evaporating dish 70 through the drain pipe 43 from the opening provided on the bottom surface of the cooling chamber 35.

More specifically, a region surrounded by the first partition wall 74 is located directly below the drain pipe 43. As a result, the drain water flowing into the drain pipe 43 from the bottom surface of the cooling chamber 35 is preferentially guided into the region surrounded by the first partition wall 74 of the evaporating dish 70. Since the region surrounded by the first partition wall 74 exists on the recess 71 adjacent to the head of the compressor 31, the heat generated by the compressor 31 is more easily transferred to this region. Therefore, the drain water stored in the evaporating dish 70 can be efficiently heated by the heat of the compressor 31, and the drain water can be evaporated in a shorter time.

A protrusion 76 extending upward is provided on the bottom surface 70d in the region surrounded by the first partition wall 74. As shown by a broken line in FIG. 8, the protrusion 76 extends upward toward the drain pipe 43. In other words, the protrusion 76 is located directly below the drain pipe 43.

By providing such a protrusion 76, the drain water dropped from the drain pipe 43 is surely guided along the protrusion 76 into the region surrounded by the first partition wall 74. As a result, it is possible to reduce dripping noise and water splash when the drain water falls directly from the drain pipe 43 to the water storage area of the evaporating dish 70, as compared with the case where the drain water falls directly from the drain pipe 43 to the water storage area.

Further, the evaporating dish 70 is provided with a second partition wall 75 in addition to the first partition wall 74. The second partition wall 75 extends substantially parallel to the side surface portion 70b. As shown in FIG. 4, the second partition wall 75 is provided closer to the substrate unit 20 than the recess 71. As a result, the second water storage region 75A can be partitioned on the side surface portion 70b-1 side adjacent to the substrate unit 20.

Compared to the first water storage area 74A, the heat of the compressor 31 is less likely to be transferred to the second water storage area 75A. Therefore, the drain water once stored in the second water storage area 75A is less likely to evaporate than the drain water once stored in the first water storage area 74A. As shown in FIG. 4, the second water storage region 75A is adjacent to the substrate unit 20 on which the control substrate 21 is mounted. By storing water in the second water storage region 75A adjacent to the substrate unit 20, the heat generated by the compressor 31 is less likely to be transferred to the substrate unit 20. Further, the heat of vaporization of water in the second water storage region 75A can be used to dissipate heat in the space near the substrate unit 20.

(Summary of the first embodiment)
As described above, the refrigerator 1 according to the present embodiment includes a refrigerating cycle 40 and a machine room 30. The refrigeration cycle 40 includes a compressor 31 and a cooler (evaporator) 32. The compressor 31 is arranged in the machine room 30. The machine room 30 is provided with an evaporating dish 70 located above the compressor 31 and from which the condensed water generated in the cooler 32 is discharged.

The bottom surface 70d of the evaporating dish 70 is provided with a recess 71 that follows the shape of the head of the compressor 31. Further, a groove 72 for exhausting heat is formed on at least one side wall (for example, the back surface 70c) from the bottom surface 70d on the outside of the evaporating dish 70, and one end of the groove 72 is continuous with the recess 71. However, the other end of the groove 72 extends to the upper end of the side wall.

According to this configuration, a part of the heat transferred from the compressor 31 to the recess 71 of the evaporating dish 70 passes through the groove 72a of the back surface 70c, which is one of the side walls, from the groove 72b formed in the bottom surface 70d. Can be made to. As a result, the heat generated by the compressor 31 can be easily released to the back side of the refrigerator 1, and the temperature rise in the machine room 30 can be suppressed. Therefore, it is possible to reduce the possibility that parts other than the compressor 31 (for example, the control board 21) arranged in the machine room 30 will break down due to the temperature rise in the machine room 30.

Further, in the present embodiment, the groove 72a is provided on the back surface portion 70c. The back surface 70c is the side wall of the evaporating dish 70 that is farthest from the storage space of the refrigerator 1. Therefore, according to this configuration, the heat generated by the compressor 31 can be discharged from the side wall farthest from the storage space, so that the influence of the heat of the compressor 31 on the storage space can be further reduced. ..

Further, in the present embodiment, the groove 72b formed in the bottom surface portion 70d of the evaporating dish 70 is continuous with the recess 71. Since the recess 71 has a shape that follows the shape of the head of the compressor 31, the heat discharged from the head of the compressor 31 is received by the recess 71, and the heat is efficiently received by the groove 72b in the back surface 70c of the evaporating dish 70. Can lead to the side. The bottom surface of the groove 72b may be located above the top of the head of the compressor 31. As a result, the heat discharged from the head of the compressor 31 is easily guided to the groove 72b without being trapped in the recess 71, and the heat dissipation efficiency of the compressor 31 is improved.

<Second embodiment>
Subsequently, a second embodiment of the present invention will be described. In the second embodiment, the arrangement position of the heat exhaust groove provided in the evaporating dish is different from that in the first embodiment. For other configurations, the same configuration as in the first embodiment can be applied. Therefore, in the second embodiment, the points different from those in the first embodiment will be mainly described.

In the first embodiment, in the evaporating dish 70, the heat exhaust groove 72a is provided on the back surface portion 70c. However, the arrangement position of the groove 72a is not limited to the back surface portion 70c. For example, the groove 72a may be provided on the side surface portion 70b. In this case, the groove 72a is not the side surface portion 70b-1 (see FIG. 4) adjacent to the substrate unit 20 on which the control board 21 is mounted, but is opposite to the side surface portion 70b-1 adjacent to the substrate unit 20. It is preferably provided on the side surface portion 70b-2 (see FIG. 4).

With this configuration, a part of the heat transferred from the compressor 31 to the recess 71 of the evaporating dish 70 can be discharged from the groove 72b formed in the bottom surface portion 70d to the side surface portion 70b-2. Since the side surface portion 70b-2 is located at a position away from the substrate unit 20, according to the above configuration, it is possible to make it difficult for the heat discharged from the groove 72b to be transferred to the substrate unit 20. Further, the heat transferred to the groove 72b of the side surface portion 70b-2 is released to the outside from the side wall of the machine room 30 (that is, the side surface portion 50b of the heat insulating box body 50).

<Third embodiment>
Subsequently, a third embodiment of the present invention will be described. In the third embodiment, the structure of the drain pipe and the protrusion of the evaporating dish is different from that of the first embodiment. For other configurations, the same configuration as in the first embodiment can be applied. Therefore, in the third embodiment, the points different from those in the first embodiment will be mainly described.

FIG. 9 schematically shows the configuration around the machine room 30 of the refrigerator 1 according to the third embodiment. The refrigerator 1 according to the present embodiment is provided with a drain pipe 343 and an evaporating dish 370 as a configuration different from that of the first embodiment. As for the configurations other than these, the same configurations as those in the first embodiment can be applied.

The drain pipe 43 described in the first embodiment is provided so as to penetrate the foamed heat insulating material 56 between the cooling chamber 35 and the machine chamber 30. On the other hand, in this embodiment, a longer drain pipe 343 is provided. The upper end of the drain pipe 343 is located near the central portion of the cooling chamber 35, and the lower end thereof is located above the inside of the machine chamber 30.

Further, the evaporating dish 370 is provided with a protrusion 376 extending upward from the bottom surface portion 70d of the evaporating dish 370. In the evaporating dish 370, the same configuration as that of the first embodiment can be applied to the configurations other than the protrusion 376. The protrusion 376 is higher than the protrusion 76 described in the first embodiment. As shown in FIG. 9, the height of the protrusion 376 is higher than the height of the side wall (for example, the back surface 70c) of the evaporating dish 370.

The upper end of the protrusion 376 is close to the lower end of the drain pipe 343. The drain water generated in the cooling chamber 35 during the defrosting operation or the like flows into the drain pipe 343 in the cooling chamber 35, and is discharged to the machine room 30 through the drain pipe 343. Then, the drain water that has reached the lower end of the drain pipe 343 is transmitted to the upper end of the protrusion 376 that is close to the bottom.

According to the above configuration, the drain water transmitted from the drain pipe 343 to the protrusion 376 is guided into the region surrounded by the first partition wall 74. As a result, it is possible to reduce dripping noise and water splash when the drain water falls directly from the drain pipe 343 to the water storage area of the evaporating dish 370, as compared with the case where the drain water falls directly from the drain pipe 343 to the water storage area.
