Description

Technical Field

[0001] The present invention relates to a cooling bank and an assembly method. Background Art

[0002] Japanese Patent Gazette No. 2009-79778 describes a refrigerator in which a machine room is provided at the lower back side of a heat-insulating box body so that cold air generated by an evaporator circulates in the box, and the machine room comprises: a compressor that compresses refrigerant; a fan for cooling the compressor that cools the compressor; a condenser that condenses the refrigerant discharged from the compressor; and an evaporating dish (drain pan) that evaporates defrost water generated by defrosting the evaporator, and the condenser and the evaporating dish are arranged side by side in the air path of the machine room, with the condenser on top and the evaporating dish on the bottom. Summary of the invention

[0003] For example, a built-in small cooling storage installed as a part of a structure such as a storage rack in a kitchen is often installed in a relatively small and deep installation space.

[0004] Such a built-in cooling storage may be installed in a predetermined installation space designed for assembling an oven or a sideboard, for example.

[0005] In such an embedded cooling storage, in order to ensure space for a storage room, etc., the machine room is usually set on the inner side (back side) of the installation space. At the bottom of the limited machine room, for example, a drain pan is arranged side by side with the compressor, and the drain pan is arranged in a manner to receive defrost water discharged from the drain hole of the drip pan above.

[0006] However, in the above-mentioned embedded cooling storage, in the setting where the defrost water cannot be discharged to the outside such as the sewer, it is necessary to force the defrost water in the drain pan to evaporate and release it to the atmosphere outside the setting space. In order to promote the evaporation of the defrost water, the drain pan is usually heated from the inside or from the outside in the high temperature part of the refrigeration cycle. However, in a built-in small cooling warehouse (particularly a refrigerator), since the operation time of the compressor is short, the drain pan is not sufficiently heated, and there is a problem that the defrost water accumulated in the drain pan is difficult to evaporate.

[0007] An object of the present disclosure is to provide a cooling storage and an assembling method in which water accumulated in a drain pan can be easily evaporated.

[0008] A cooling storage according to one aspect of the present disclosure includes a compressor, at least one pipe connected to the compressor, and a drain pan. At least a portion of the drain pan is provided adjacent to the compressor in the left-right direction. The pipe includes a stopper portion, which is a portion located between the compressor and the drain pan and does not exceed the height of the peripheral wall of the drain pan. The drain pan has a bulging portion. The bulging portion is a portion that bulges toward the compressor side in the left-right direction relative to an end portion of the stopper portion on the drain pan side in the left-right direction.

[0009] According to one aspect of the present disclosure, a cooling storage and an assembling method can be provided in which water accumulated in a drain pan can be easily evaporated. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Hereinafter, each embodiment of the present disclosure will be described with reference to the drawings. In addition, in the drawings, the same reference numerals are given to the same components.

[0012] <Cooling room> In the present disclosure, a "cooling storage" refers to a whole that has an internal space (storage room) whose temperature is lower than the outside air temperature and can lower the temperature of the stored items. The cooling storage may be, for example, a refrigerator or a freezer. The cooling storage may have only one storage room or may have multiple storage rooms. In the case where the cooling storage has multiple storage rooms, the multiple storage rooms may also include at least two of a refrigerating room, a freezing room, a vegetable room, a zero-degree room, a partial freezing room, and the like.

[0013] The cooling store 1 of this embodiment is a so-called built-in cooling store installed in a predetermined installation space. The cooling store 1 can be installed in a part of a storage rack 9 (installation space for assembling an oven, a cabinet, a storage rack, etc.), that is, in a predetermined installation space (see Figure 1 and Figure 3 ). The cooling storage can be installed on a newly built kitchen storage rack from the beginning, or it can be installed later on existing kitchen storage racks and other structures.

[0014] For example, when a cooling storage is installed in the installation space in a conventional kitchen storage rack, the installation space often includes space for installing a drain pipe or the like on the back side thereof, and there is a surplus space on the back side of the installation space. In a cooling storage installed in such an installation space, by providing the machine room on the rear side, the dimensions of the storage room and the like in the vertical and horizontal directions can be maximized, and more space in the storage room can be occupied on the front side.

[0015] First, the main reference Figures 1 to 4 The overall structure of the cooling storage 1 according to the first embodiment will be described. Figure 3 The longitudinal section view shown is in Figure 3 The smaller sectional view at the lower right shows the III-III section of the main view.

[0016] In addition, in this specification, the surface provided with the door is referred to as the front surface (or front face) of the cooling cabinet 1. And, based on the front surface and the configuration of the cooling cabinet 1 in general, the surfaces of the cooling cabinet 1 are referred to as the back surface, the top surface, the bottom surface, and the side surface. In addition, the directions of the components constituting the cooling cabinet 1 are sometimes also expressed based on the configuration of the cooling cabinet 1.

[0017] The structural frame of the cooling store 1 is mainly composed of a heat-insulating box body 8. The heat-insulating box body 8 forms a storage room 10 (refrigerating room, freezing room, etc.) as a storage space of the cooling store 1.

[0018] A machine room 13 is formed at the lower part of the back side of the storage room 10. In the machine room 13, for example, a refrigeration cycle including a compressor 3 is formed, and a fan 7 causes the air in the machine room 13 to flow upward along the back side of the heat-insulating box body 8, and flows along the top surface of the heat-insulating box body 8 toward the front surface, and is discharged from the front surface side of the heat-insulating box body 8. Control circuit unit 19 and the like may be provided on the upper surface side or the rear surface side of storage chamber 10 .

[0019] The refrigeration cycle is mainly composed of a compressor 3, a condenser, an expander, an evaporator 2 (cooler), etc. These components are connected via a refrigerant pipe for circulating the refrigerant. In addition, in this embodiment, the evaporator 2 is arranged above the compressor 3 (see Figure 8 ).

[0020] The cooling cabinet is not particularly limited, and a drawer type cooling cabinet can be cited as an example. For example, in the cooling cabinet installed on the storage rack 9, the upper surface of the storage rack 9 constitutes a counter, which is close to the height of a person's waist. Therefore, the drawer type that takes out and puts in items from the upper part is easier to use. Main reference Figure 2 The drawer-type cooling cabinet 1 includes, for example, a cooling cabinet body 11 having a storage space 11a with an opening, and a drawer 12 supported in the storage space 11a of the cooling cabinet body 11 so as to be pushable and pullable. In this case, the opening of the storage space 11a of the cooling cabinet body 11 is closed by a door 121 of the drawer 12, thereby forming a storage room 10. In addition, a grip portion 121a for operating the drawer 12 to be pushed or pulled may be provided on the upper front surface of the door 121 of the drawer 12. An operating portion 11b for operating the cooling storage 1 may also be provided. The drawer 12 includes a door 121 on the front surface, a receiving frame 122 (integrated with a guide rail mechanism 124 ) fixed to the door 121 , and a tray 123 supported by the receiving frame 122 . The drawer 12 is supported by a guide rail mechanism 124 that is freely pushed and pulled in the front-rear direction. The guide rail mechanism 124 is provided between the receiving frame 122 and the inner wall of the storage chamber 10 (cooling cabinet body 11). The drawer 12 can be pulled out greatly by a two-stage guide rail mechanism, for example, so that it is easy to observe from the user's upper field of vision.

[0021] Next, refer to Figure 5 as well as Figure 6 The cooling storage 1 of the present embodiment includes a compressor 3 , at least one pipe 31 or 32 connected to the compressor 3 , and a drain pan 4 . The drain pan 4 is disposed at the same height position as the compressor 3 (side by side).

[0022] Reference Figure 7The pipes 31 and 32 include stoppers 31a and 32a. Here, the stoppers are portions located between the compressor 3 and the drain pan 4 (in the left-right direction A) and do not exceed the height of the peripheral wall of the drain pan 4. That is, the stoppers are portions that can interfere with the drain pan 4 when the drain pan 4 is inserted into the machine room 13 from the horizontal direction, particularly from the front-back direction B, for example.

[0023] The dam portion is a portion of the pipe that is closer to the drain pan 4 than the compressor 3 , but the pipe (heat pipe for promoting evaporation, etc.) disposed inside the drain pan 4 is not included in the dam portion. Among the refrigerant pipes constituting the refrigeration cycle, the pipes on the heat dissipation side (such as the pipes 32 on the discharge side connected to the compressor 3) from the compressor 3 to the condenser of the expander can be used to promote the evaporation of the defrosted water in the drain pan 4. Therefore, by arranging the pipes on the heat dissipation side inside or near the drain pan 4, the water accumulated in the drain pan 4 can be easily evaporated. In this way, there is a case where the pipe (heat pipe 33) on the heat dissipation side is set inside the drain pan 4. Even in this case, as described later, in the process of setting the drain pan 4, if the heat pipe 33 is temporarily lifted to a position higher than the side wall of the drain pan 4, the drain pan 4 can be inserted, so that the heat pipe 33 does not become an obstacle to the setting of the drain pan 4.

[0024] (Drain pan) In the cooling storage of the present embodiment, drain pan 4 has bulging parts 41 and 42 . The bulges 41 and 42 are formed in a plan view (a plan view viewed from above the cooling chamber: see Figure 7 ) The portion bulging toward the compressor 3 in the left-right direction A more than the end portions 31b and 32b on the drain pan 4 side in the left-right direction A of the blocking portions 31a and 32a. That is, in a plan view, at least a portion of the bulging portions 41, 42 overlaps with at least a portion of the blocking portions 31a, 32a of the pipes 31, 32 in the front-rear direction B. In other words, in a back view, at least a portion of the bulging portions 41, 42 overlaps with at least a portion of the blocking portions 31a, 32a of the pipes 31, 32.

[0025] exist Figure 7 In the figure, the bulging portions 41, 42 are portions (first portions 41a, 42a, second portions 41b, and front portions 41c, 42c) that bulge further toward the compressor 3 in the left-right direction A than the end portion 32b (dashed line L1) on the drain pan 4 side of the blocking portion 32a in the left-right direction A.

[0026] Furthermore, the bulging portions 41 and 42 are also portions that bulge out further toward the compressor 3 in the left-right direction A than the end portion 31b (dashed line L2) on the drain pan 4 side of the blocking portion 31a in the left-right direction A. As shown in the figure, when the height of the peripheral wall 43 of the drain pan 4 is higher than the lower end of the pipe 32 (and the pipe 31), the bulging portion only needs to be a portion that bulges out further toward the compressor 3 than the end portion 32b (dashed line L1), and does not necessarily need to bulge out further toward the compressor 3 than the end portion 31b (dashed line L2).

[0027] The drain pan 4 has bulging portions 41, 42 (in other words, the end portion (peripheral wall 43) of the drain pan 4 on the compressor 3 side is extended toward the inner side of the drain pan in the horizontal direction (at a position other than the bulging portions 41, 42). Figure 7 The drain pan 4 is formed by a hollow portion (right side in the middle), thereby avoiding the blocking portions 31a and 32a and increasing the evaporation area of ​​the drain pan 4 (the area where the surface of the water accumulated in the drain pan 4 contacts the air). If the temperature of the water and the conditions of ventilation, temperature and humidity on the water surface are the same, the evaporation amount is proportional to the water surface area. In this way, the water accumulated in the drain pan 4 can be easily evaporated.

[0028] In addition, in the case where the drain pan 4 is located at the back of the installation space, such as in an embedded type cooling storage, and it is difficult for the user to check the drain pan 4, the user may not notice even if the drain pan 4 overflows. Therefore, it is preferable to increase the volume (upper limit of water storage) of the drain pan 4, thereby reducing the possibility of overflowing water. From the viewpoint of increasing the volume of the drain pan 4, it is preferable that the peripheral wall 43 of the drain pan 4 is high. However, as the peripheral wall 43 of the drain pan 4 becomes higher, the number of pipes (blocking parts) that become obstacles to the installation of the drain pan 4 increases, and it is difficult to increase the evaporation area of ​​the drain pan. In this embodiment, the peripheral wall 43 of the drain pan 4 is made higher than the height of the blocking parts 31 a and 32 a of the pipes 31 and 32 of the compressor 3 , so that the volume of the drain pan 4 can be increased, and the evaporation area of ​​the drain pan 4 can be increased by the bulging parts 41 and 42 .

[0029] In addition, Figure 7 In the cooling storage shown in the figure, the drain pan 4 has a bulging portion 41 on the front side (front surface side: door side of the cooling storage) of the blocking portion 31a, 32a and a bulging portion 42 on the rear side (back side). Thus, preferably, the bulging portions 41, 42 exist on both sides of the blocking portion 31a, 32a in the front-rear direction B. In this case, compared with the case where the bulge is provided only on the front side or the rear side, the evaporation area of ​​the drain pan 4 (the area where the water accumulated in the drain pan 4 contacts the air) can be increased, so the water accumulated in the drain pan evaporates more easily. In addition, the maximum length side and the maximum short side of the drain pan 4 do not change significantly when viewed from directly above. In other words, when the vertical direction of the drain pan 4 is simply used as the movable direction of the molding die, the investment amount for changing the die size can also be suppressed.

[0030] The peripheral wall 43 of the drain pan 4 (see Figure 6 ) is preferably higher than the lower end of the connection between the compressor 3 and the pipes 31, 32. The height of the peripheral wall 43 of the drain pan 4 is preferably constant. When the height of the peripheral wall 43 is not constant, the height of the portion of the peripheral wall 43 closest to the pipes 31 and 32 is preferably higher than the lower end of the connection between the compressor 3 and the pipes 31 and 32.

[0031] In the compressor 3 installed in the machine room 13 of the embedded cooling storage 1, the pipes 31 and 32 mostly extend from the compressor 3 roughly in the left-right direction A of the cooling storage 1. This is because piping above and below the compressor 3 will cause the space of the machine room to become larger. Therefore, especially when the height of the peripheral wall 43 of the drain pan 4 is higher than the lower end of the connection between the compressor 3 and the pipes 31 and 32, the parts (blocking parts 31a and 32a) extending from the compressor 3 of the pipes 31 and 32 to the drain pan 4 side in the left-right direction A all become obstacles to the installation of the drain pan 4, making it difficult to increase the evaporation area of ​​the drain pan. The effect of this embodiment, which is capable of increasing (increasing the volume of the drain pan 4) the evaporation area by making the directions of the blocking portion 31a and the blocking portion 32a consistent (the directions of the plurality of blocking portions are consistent in the left-right direction) and providing the bulges 41 and 42 on the basis of ensuring the movement in the direction A relative to the drain pan 4, is particularly useful in such a situation.

[0032] In addition, it is preferable that at least the bulging portion 41 located in front of the blocking portions 31a and 32a bulges further toward the compressor 3 in the left-right direction than the end portion 3a on the drain pan 4 side in the left-right direction A of the compressor 3. Figure 7 As shown in FIG. 1 , the bulged portion 41 preferably has a front end portion 41 c which is a portion closer to the compressor 3 than the end portion 3 a (dashed line L3 ). In other words, preferably, when viewed from above, at least a portion of the bulged portion 41 located in front of the blocking portions 31a, 32a overlaps with at least a portion of the compressor 3 in the front-rear direction. Alternatively, preferably, when viewed from the back, at least a portion of the bulged portion 41 located in front of the blocking portions 31a, 32a overlaps with at least a portion of the compressor 3. In this case, there is no need to provide a region surrounded by a partially high inner wall in the drain pan 4 in order to increase the total water storage capacity of the drain pan 4. The defrost water is widely diffused in the drain pan 4, so the evaporation area can be further increased. Furthermore, when the drain pan is inserted from the back side of the cooling store as in the past, the compressor 3 becomes an obstacle, so the front end portion 41c of the bulge 41 cannot be provided. According to the cooling store assembly method described later including the step of inserting the drain pan 4 from the side (left-right direction A) of the cooling store in which the compressor 3 is provided, the front end portion 41c of the bulge 41 can be provided.

[0033] Furthermore, it is preferred that the bulging portion 42 located at the rear side of the blocking portions 31a, 32a also bulges further toward the compressor 3 in the left-right direction than the end portion 3a on the drain pan 4 side in the left-right direction A of the compressor 3 (i.e., Figure 7 As shown, the bulged portion 42 also has a front end portion 42c). In this case, there is no need to provide a region surrounded by a partially high inner wall in the drain pan 4 in order to increase the total water storage capacity of the drain pan 4. The defrost water is widely diffused in the drain pan 4, so the evaporation area can be further increased.

[0034] (Drip tray) like Figure 8 As shown, the cooling storage 1 of the present embodiment may further include a drip tray (water receiving pan) above the drain pan 4 , and the drip tray (water receiving pan) may have a drainage hole for allowing the defrost water to flow through the drain pan 4 .

[0035] The drip tray 6 is disposed, for example, below the evaporator 2. The drip tray 6 has a drain hole 61 at the deepest part (see Figure 8 , Fig. 9 ). By using the drip tray 6, frost and ice attached to the evaporator 2 melt, and the fallen water and ice flakes can be collected and discharged to the discharge hole 61 (drain tray 4, etc.).

[0036] Here, the drain hole 61 of the drip tray 6 is preferably located above the bulging parts 41 , 42 of the drain tray 4 .

[0037] In the drip tray 6, the discharge hole 61 for discharging water and ice flakes is preferably arranged at a position close to the center in the left-right direction of the cooling storage. In order to make water flow smoothly to the drain hole 61, it is necessary to set the inclination angle from the peripheral end of the drip tray 6 to the drain hole 61 on the upper surface of the drip tray 6 to be greater than a specified value. Here, the longer the longest distance from the peripheral end of the drip tray 6 to the drain hole 61, the lower the position of the drain hole 61 needs to be, and the height of the entire drip tray 6 needs to be increased. In the case where the drain hole 61 is located at a position away from the center of the left-right direction (of the cooling tank) which is the length direction of the drip tray 6, the longest distance from the peripheral end of the drip tray 6 to the drain hole 61 becomes longer, so it is necessary to increase the height of the entire drip tray 6. Therefore, the drain hole 61 is preferably provided at a position close to the center of the left-right direction of the cooling tank.

[0038] Here, the drain hole 61 of the drip tray needs to be arranged in a manner that the drain tray 4 is located directly below the drain hole 61, but in the present embodiment, since the drain tray 4 is expanded to the center side in the left-right direction by having bulges 41, 42, the drain hole 61 of the drip tray can be arranged at a position close to the center in the left-right direction.

[0039] (How to assemble the cooling cabinet) The present disclosure also relates to a method for assembling a cooling storage including a compressor 3 , at least one pipe 31 , 32 connected to the compressor 3 , and a drain pan 4 . Reference Fig.10 The assembly method includes a step of inserting (at least a portion of) the drain pan 4 from the side (left-right direction A) of the cooling storage where the compressor 3 is installed and installing it at the same height position as the compressor 3 (drain pan installation step). In addition, in the case of a normal cooling storage, the side surface is the part that contacts the user's eyes and hands. In order to maintain the appearance or to protect the user from the high temperature parts such as the heat pipe and the rotating parts such as the fan, the side surface of the machine room needs to be covered with a protective component. The simplest structure is to extend the side shell sheet metal to the side surface of the machine room. However, in the case of a dedicated embedded design, since the above-mentioned protective component is not required, it is easy to perform the above-mentioned process. Furthermore, it is preferable that the insertion direction of the drain pan 4 coincide with the direction in which the blocking portions 31 a and 32 a of the pipes 31 and 32 of the compressor 3 extend.

[0040] In the drain pan installation process, by Fig.10 The drain pan 4 is inserted in the direction of the arrow (extending along the left-right direction A of the cooling storage 1), and the blocking parts 31a, 32a of the piping 31, 32 of the compressor 3 are not hindered, so the bulging parts 41, 42 of the drain pan 4 can be inserted to a deeper position in the left-right direction A of the cooling storage 1. On the other hand, when the drain pan 4 is inserted from the back side of the cooling store 1 as in the conventional method, the stoppers 31a and 32a cannot be avoided, and therefore, the bulging portion 41 cannot be provided in the drain pan 4. Figure 7 In the embodiment, it is impossible to provide the drain pan 4 having the bulging portion 41 located in front of the blocking portions 31a and 32a. Therefore, it is difficult to increase the total water storage capacity and evaporation area of ​​the drain pan 4. In this embodiment and process, the drain pan 4 having the bulging portion 41 located in front of the blocking portions 31a and 32a can be provided. Figure 7 As shown, the bulge 41 is close to the storage space 11a and is arranged at a position adjacent to the compressor 3. Therefore, by accumulating in the bulge 41, it is possible to suppress the exhaust heat from the compressor 3 from being transferred to the storage space 11a, and since it is easily exposed to the exhaust heat from the compressor 3, the defrost water stored in the drain pan 4 can be evaporated efficiently. In addition, as described above, the position where the bulge 41 is arranged is the space sandwiched between the back side of the heat-insulating box 8 forming the storage space 11a and the compressor 3, and since it is a space that is difficult to reach by hand, it is a space that is difficult to be used for the arrangement of mechanisms such as the pipes 31 and 32. According to this embodiment and process, the excellent effect of being able to effectively utilize the space and being able to appropriately handle the exhaust heat from the compressor 3 is achieved.

[0041] Furthermore, generally, the compressor 3, the bottom plate, and the like have portions that need to be joined by welding, and therefore heat-sensitive resin parts such as a drain pan are provided after the compressor 3 and the like are assembled. However, in the above-mentioned assembly method, components such as the hanger 14 (reinforcement metal member) that become obstacles when the drain pan 4 is inserted from the side are not assembled before the drain pan 4 is installed, but are assembled after the drain pan 4 is installed (see Figure 5 as well as Fig.10 ).

[0042] In addition, at least a portion of the heat pipe 33 is formed of a member that can be deformed around the drain pan 4, and in the drain pan installation process, the heat pipe 33 is inserted into the drain pan 4 while being lifted to a position higher than the side wall of the drain pan 4. After the drain pan 4 is installed, the heat pipe 33 is installed inside the drain pan 4. In addition, Fig.10 The heat pipe 33 shown shows the configuration after being arranged inside the drain pan 4 .

[0043] It should be understood that the embodiments disclosed herein are illustrative in all respects and are not restrictive. The scope of the present disclosure is not indicated by the above description but by the claims, and is intended to include all changes within the meaning and scope equivalent to the claims. In addition, the configurations obtained by combining the configurations of the different embodiments described in this specification are also included in the scope of the present disclosure.
