Detailed Description
Embodiments of the present invention will be described below with reference to the drawings. In the following description, the same components are given the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.
< first embodiment >
(integral constitution of refrigerator)
First, the overall structure of the refrigerator 1 according to the first embodiment will be described. Fig. 1 shows the structure of the back side of the refrigerator 1. In addition, fig. 2 shows an internal structure of the refrigerator 1. In fig. 2, the components in the equipment room 30 other than the compressor 31 are not shown.
As shown in fig. 2, refrigerator 1 includes first refrigerating room 11 in an upper stage, freezing room 12 in a middle stage, second refrigerating room 13 in a lower stage, and the like. A refrigerating chamber door 11a is provided on the first refrigerating chamber 11. A freezing chamber door 12a is provided on the freezing chamber 12. A refrigerating chamber door 13a is provided on the second refrigerating chamber 13.
As described above, the refrigerator 1 according to the present embodiment is divided into the upper layer portion, the middle layer portion, and the lower layer portion, 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 thereto.
In the present embodiment, the surface on which the door is provided is referred to as the front surface or front surface of the refrigerator. The respective surfaces of the refrigerator 1 are set as an upper surface, a side surface, a rear surface, and a bottom surface based on the front surface and positions where the refrigerator 1 is installed in a normal state.
The interior of the refrigerator 1 is provided with a freezing cycle 40. The refrigeration cycle 40 is configured by connecting a compressor 31, a condenser (not shown), an expander (not shown), and a cooler (evaporator) 32 via a refrigerant pipe (refrigerant flow passage) through which a refrigerant flows.
As shown in fig. 2, the compressor 31 is disposed in the equipment room 30 provided on the rear surface side of the bottom of the refrigerator 1. The cooler 32 is disposed in a cooling chamber 35 provided on the rear surface side of the refrigerator 1. The cooling chamber 35 is provided with a cooling fan 33 and the like in addition to the cooler 32. The cooling fan 33 is provided to circulate air between the cooling chamber 35 and each storage space.
In addition, a control unit is provided inside the refrigerator 1. The control unit is disposed on a control board 21 described later, for example. The control unit controls the operation of the refrigeration cycle 40. That is, the control unit starts the operation of the refrigeration cycle by driving the compressor 31, and causes the refrigerant to flow through the cycle.
Specifically, the high-temperature and high-pressure refrigerant compressed by the compressor 31 is condensed while dissipating heat in the condenser. The high-pressure refrigerant is expanded in the expander to have a low temperature and a low pressure, and is sent to the cooler 32 serving as an evaporator. The refrigerant flowing into the cooler 32 exchanges heat with the cold air flowing through the cooling chamber 35, evaporates while absorbing heat, and is a low-temperature gas refrigerant, which is sent to the compressor 31. In this way, the refrigerant circulates and the refrigeration cycle operates, and cold air is generated by the airflow that has exchanged heat with the cooler 32.
(construction of Heat insulation Box)
In the refrigerator 1, a heat insulating box 50 is provided as a heat insulating structure for insulating each storage space from the surroundings. The heat-insulated box 50 is provided to cover the outer circumference of the refrigerator 1. As shown in fig. 2, the heat insulating box 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 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 50 d. The inner case 62 forms the inner peripheral surface of the heat insulating case 50. In addition, the inner case 62 forms a boundary of the storage space (e.g., the first refrigerating compartment 11, the freezing compartment 12, the second refrigerating compartment 13) and the cooling compartment 35.
A space for disposing the equipment room 30 is formed on the rear surface side of the bottom of the heat insulating box 50. That is, the equipment room 30 is disposed outside the heat insulating box 50. This is because the temperature in the equipment room 30 rises as the compressor 31 operates.
The vacuum heat insulator 51 and the foam heat insulator 56 are provided in the space between the outer box 61 and the inner box 62. The vacuum heat insulating material 51 is a sheet-like or plate-like heat insulating material. The vacuum heat insulating material 51 is disposed on, for example, a side surface, an upper surface, a bottom surface, a back surface, and the like of the refrigerator 1. For example, the foamed heat insulating material 56 may be formed of foamed polyurethane (also referred to as rigid polyurethane foam) or the like.
(construction of the interior of the Equipment Room)
Next, a more detailed structure of the equipment room 30 provided below the rear surface side of the heat insulating box 50 will be described with reference to fig. 1 and the like. Fig. 1 shows a rear surface portion of the heat insulating box 50 with a rear surface cover covering a rear surface of the equipment room 30 removed. Fig. 3 shows a state in which the substrate unit 20 disposed in the equipment room 30 is removed from the refrigerator 1 shown in fig. 1. Fig. 4 schematically shows the positional relationship of the respective constituent components (i.e., the compressor 31, the substrate unit 20, and the evaporation pan 70) arranged in the equipment room 30.
The rear surface portion 50c of the heat insulating box 50 is mainly constituted by the back plate of the outer box 61. The device chamber 30 is located below the back surface portion 50 c. The equipment room 30 is mainly defined by a bottom plate 63 forming a bottom surface portion 50d of the heat insulating box 50. As shown in fig. 2 and the like, a rear portion of the bottom plate 63 protrudes upward. The rearmost side of the bottom plate 63 has a substantially flat shape in the horizontal direction, and this portion forms a ceiling portion 63a of the equipment room 30.
The floor 63 has a ceiling portion 63a and a raised portion 63c as regions for defining the facility room 30 (see fig. 2). The ceiling portion 63a forms an upper surface (ceiling) of the equipment room 30. The rising portion 63c forms the front face of the apparatus chamber 30. The side surface of the equipment room 30 is formed by the side surface portion 50b of the outer box 61.
The compressor 31, the substrate unit 20, the evaporation pan 70, and the like are mainly disposed in the equipment room 30. The compressor 31 is disposed slightly to the right (left when viewed from the front) in the equipment room 30 as viewed from the rear. The substrate unit 20 is disposed beside the compressor 31. In the example shown in fig. 1, the substrate unit 20 is disposed on the left side of the compressor 31 (the right side of the compressor 31 when viewed from the front). However, in another example, the substrate unit 20 may be disposed on the right side of the compressor 31 (the left side of the compressor 31 when viewed from the front).
In the substrate unit 20, a control substrate 21 is disposed. As shown in fig. 4, the control board 21 is arranged in a vertical direction (a direction orthogonal to a horizontal plane). More specifically, the control board 21 is disposed substantially parallel to a side surface portion 50b of the heat insulating box 50 forming a side wall of the equipment chamber 30.
In the equipment room 30, a harness 38 (see fig. 3) including various wirings is disposed on the front side of the space 20A in which the substrate unit 20 is disposed. The wire harness 38 is connected to various electric components in the heat insulating box 50, various electric components in the equipment room 30 such as the compressor 31, the control board 21, the power supply unit (not shown), and the like.
The evaporating dish 70 is located above the compressor 31. The evaporating dish 70 discharges condensed water (also referred to as drain water) generated in the cooling chamber 35. The condensed water generated in the cooling chamber 35 includes, for example, defrosting water generated when the cooler 32 is defrosted. As shown in fig. 4, a recess 71 curved upward is formed in the bottom surface portion 70d of the evaporation pan 70. The recess 71 is shaped to follow the shape of the upper portion (head) of the compressor 31.
(constitution of evaporating dish)
Next, a more detailed structure of the evaporation pan 70 will be described. Fig. 5, 6, and 7 show the structure of the evaporation pan 70. Fig. 5 is a perspective view of the evaporation pan 70 as viewed from above the back side. Fig. 6 is a perspective view of the evaporation pan 70 as viewed from above on the front surface side. Fig. 7 is a perspective view of evaporation pan 70 as viewed from below the back surface side.
The evaporation pan 70 has a substantially rectangular parallelepiped box shape. The upper portion of the evaporating dish 70 is open. The outer shape of the evaporation pan 70 is mainly constituted by a front surface 70a, left and right side surfaces 70b and 70b, a back surface 70c, and a bottom surface 70 d. The name of each face is defined according to the position of the evaporation pan 70 after being attached to the refrigerator 1. By having these respective surface portions, the drain water discharged from the drain pipe 43 (see fig. 8) disposed above can be stored.
The front surface 70a, the left and right side surfaces 70b and 70b, and the back surface 70c form the side walls of the evaporation pan 70.
The bottom surface portion 70d of the evaporation pan 70 is provided with a recess 71 along the head shape of the compressor 31. For example, the recess 71 has a shape in which an elliptical plane is projected in a dome shape (see fig. 7). The evaporating dish 70 is provided with a heat-discharging groove 72 for discharging heat generated by the compressor 31 on the outer surface side. The groove 72 extends from the bottom surface portion 70d to the back surface portion 70 c. That is, the end of the groove 72b formed in the bottom surface portion 70d is continuous with the recess 71. The end of groove 72a formed in back surface portion 70c extends to the upper end of back surface portion 70 c.
In this way, in evaporation pan 70, groove 72 extending continuously from recess 71 near the head of compressor 31 to back surface portion 70c is formed. This allows heat generated by compressor 31 to be guided to back surface portion 70c of evaporation pan 70 via groove 72.
The inside of the evaporation pan 70 is divided into a plurality of regions by several partitions (for example, a first partition 74 and a second partition 75) provided upright from the bottom surface portion 70d, and the like.
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 portion 74a of first partition 74 located on the rear surface portion 70c side linearly extends substantially in parallel with rear surface portion 70 c. Thereby, a region surrounded by the first partition 74 is formed.
A drain pipe 43 is disposed above the region partitioned by the first partition wall 74. Fig. 8 shows the positional relationship of the drain pipe 43 and the evaporating dish 70. The drain pipe 43 extends from the cooling chamber 35 toward the equipment chamber 30. The drain pipe 43 is provided to penetrate the foamed heat insulating material 56 between the cooling chamber 35 and the equipment room 30.
As shown in fig. 8, the evaporation pan 70 is disposed below the drain pipe 43. Drain water generated in cooling chamber 35 during defrosting operation or the like is discharged from an opening provided in the bottom surface of cooling chamber 35 to evaporation pan 70 through drain pipe 43.
More specifically, the region surrounded by first partition wall 74 is located directly below drain pipe 43. Thus, the drain flowing into the drain pipe 43 from the bottom surface of the cooling chamber 35 is preferentially guided to the region surrounded by the first partition wall 74 of the evaporation pan 70. Since the region surrounded by the first partition wall 74 is present in the recess 71 adjacent to the head of the compressor 31, the heat generated by the compressor 31 is more easily transmitted to the region. Therefore, the discharge water accumulated in the evaporation pan 70 can be efficiently heated by the heat of the compressor 31, and the discharge water can be evaporated in a shorter time.
Further, a protrusion 76 extending upward is provided on the bottom surface portion 70d in the region surrounded by the first partition wall 74. As shown by the broken line in fig. 8, the projection 76 extends upward toward the drain pipe 43. In other words, the projection 76 is located directly below the drain pipe 43.
By providing such a protrusion 76, the drain dropped from the drain pipe 43 is reliably guided along the protrusion 76 into the region surrounded by the first partition wall 74. This can reduce dripping noise, splash, and the like at the time of dripping, as compared with a case where the drain water directly drips from the drain pipe 43 onto the water storage region of the evaporation pan 70.
In addition, the evaporation pan 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 70 b. As shown in fig. 4, the second partition wall 75 is provided on the side closer to the substrate unit 20 than the recess 71. Thereby, the second water storage region 75A can be defined on the side surface portion 70b-1 side adjacent to the substrate unit 20.
The heat of the compressor 31 is difficult to be transferred to the second water storage area 75A compared to the first water storage area 74A. Therefore, the drain water temporarily accumulated in the second water storage area 75A is less likely to evaporate than the drain water temporarily accumulated 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. Since water is accumulated in the second water storage area 75A adjacent to the substrate unit 20, heat generated by the compressor 31 is difficult to be transferred to the substrate unit 20. Further, the heat of evaporation of the water in the second water storage region 75A can be dissipated to the space near the substrate unit 20.
(summary of the first embodiment)
As described above, the refrigerator 1 according to the present embodiment includes the refrigeration cycle 40 and the equipment room 30. The refrigeration cycle 40 includes a compressor 31 and a cooler (evaporator) 32. The compressor 31 is disposed in the equipment room 30. The equipment room 30 is provided with an evaporation pan 70, and the evaporation pan 70 is located above the compressor 31 and discharges dew condensation water generated in the cooler 32.
The bottom surface portion 70d of the evaporation pan 70 is provided with a recess 71 along the head shape of the compressor 31. Further, a groove 72 for heat radiation is formed from bottom portion 70d on the outer side of evaporation pan 70 to at least one side wall (for example, back portion 70c), one end portion of groove 72 is continuous with recess 71, and the other end portion of groove 72 extends to the upper end of the side wall.
According to this configuration, a part of the heat transferred from compressor 31 to concave portion 71 of evaporation pan 70 can pass through groove 72a of rear surface portion 70c, which is one of the side walls, from groove 72b formed in bottom surface portion 70 d. This makes it easy to dissipate the heat generated by the compressor 31 to the rear surface side of the refrigerator 1, and suppresses a temperature rise in the device chamber 30. Therefore, the temperature of the equipment room 30 increases, and the possibility of a failure occurring in a component (for example, the control board 21 or the like) disposed in the equipment room 30 other than the compressor 31 can be reduced.
In the present embodiment, the groove 72a is provided in the back surface portion 70 c. The back surface portion 70c is a sidewall farthest from the storage space of the refrigerator 1 among the sidewalls of the evaporation pan 70. Therefore, according to this configuration, since the heat generated by the compressor 31 can be discharged from the side wall farthest from the storage space, the influence of the heat of the compressor 31 on the storage space can be further reduced.
In the present embodiment, the groove 72b formed in the bottom surface portion 70d of the evaporation pan 70 is continuous with the recess 71. Since the recess 71 has a shape along the shape of the head of the compressor 31, the heat discharged from the head of the compressor 31 can be received by the recess 71, and the heat can be efficiently guided to the back surface portion 70c side of the evaporation pan 70 through the groove 72 b. The bottom surface of the groove 72b may be located further above the top of the head of the compressor 31. This prevents heat discharged from the head of the compressor 31 from accumulating in the recess 71, and the heat is easily guided to the grooves 72b, thereby improving the heat radiation efficiency of the compressor 31.
< second embodiment >
Next, a second embodiment of the present invention will be explained. In the second embodiment, the arrangement position of the heat-discharging grooves provided in the evaporation pan is different from that in the first embodiment. The other configurations may be the same as those of the first embodiment. Therefore, the second embodiment will be described mainly focusing on differences from the first embodiment.
In the first embodiment, the evaporation pan 70 has the grooves 72a for heat dissipation provided in the back surface portion 70 c. However, the position of the groove 72a is not limited to the back surface portion 70 c. For example, the groove 72a may be provided in the side surface portion 70 b. In this case, the groove 72a is preferably provided in the side surface portion 70b-2 (see fig. 4) opposite to the side surface portion 70b-1 adjacent to the substrate unit 20, rather than the side surface portion 70b-1 (see fig. 4) adjacent to the substrate unit 20 on which the control substrate 21 is mounted.
With this configuration, a part of the heat transferred from the compressor 31 to the recess 71 of the evaporation pan 70 can be discharged from the groove 72b formed in the bottom surface portion 70d to the side surface portion 70 b-2. Since the side surface portion 70b-2 is located at a position away from the substrate unit 20, the heat discharged from the groove 72b can be made difficult to be transmitted to the substrate unit 20 by the above-described configuration. The heat transferred to the grooves 72b of the side surface portion 70b-2 is discharged to the outside from the side wall of the equipment room 30 (i.e., the side surface portion 50b of the heat insulation box 50).
< third embodiment >
Next, a third embodiment of the present invention will be explained. In the third embodiment, the drain pipe and the projection of the evaporation pan are different in configuration from those of the first embodiment. The other configurations may be the same as those of the first embodiment. Therefore, the third embodiment will be described mainly focusing on differences from the first embodiment.
Fig. 9 schematically shows the structure around the equipment 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 evaporation pan 370 as a configuration different from that of the first embodiment. The other structure may be the same as that of the first embodiment.
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 equipment room 30. In contrast, in the present embodiment, a long drain pipe 343 is provided. The drain pipe 343 has an upper end located near the center of the cooling chamber 35 and a lower end located above the inside of the equipment room 30.
Further, the evaporation pan 370 is provided with a protrusion 376 extending upward from the bottom surface 70d of the evaporation pan 370. In the evaporation pan 370, the structure other than the protrusion 376 may be the same as that of the first embodiment. 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 (e.g., the back surface portion 70c) of the evaporation pan 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 flows into the drain pipe 343 in the cooling chamber 35 and is discharged to the equipment room 30 along the drain pipe 343. The drain water reaching the lower end of the drain pipe 343 is transmitted to the upper end of the protrusion 376 located immediately below.
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. This can reduce dripping noise, splash, and the like at the time of dripping, as compared with a case where the drain water directly drips from the drain pipe 343 into the water storage region of the evaporation pan 370.
(conclusion)
A refrigerator (e.g., refrigerator 1) according to an aspect of the present invention includes a refrigeration cycle (e.g., refrigeration cycle 40) including a compressor (e.g., compressor 31) and an evaporator (e.g., cooler 32), an equipment room (e.g., equipment room 30) in which the compressor is disposed, and an evaporation pan (e.g., evaporation pan 70, 370) located above the compressor and configured to discharge condensed water generated in the evaporator.
