Description

[Technical field]

[0001] The present invention relates to an improvement in drainage structure in refrigerators such as refrigerated showcases and commercial refrigerators. [Background technology]

[0002] Generally, many refrigerators have legs at the bottom of their main body cases to keep the refrigerator body above the floor and to stabilize the installation position of the refrigerator. In refrigerators with such legs, a gap is formed between the main body case and the floor, and it is known, for example in Patent Document 1, to provide a drain trap that constitutes a drainage structure in the gap. Drain water that accumulates in the drain trap is discharged to the outside of the refrigerator through a drain hose. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2014-156958 A Summary of the Invention [Problem to be solved by the invention]

[0004] For example, when the load strength per unit area of ​​the floor on which the refrigerator is installed is small, the refrigerator is installed with the legs removed and the main case in close contact with the floor surface. In addition, in a food processing device with a cart shelf that stores a cart with a food tray and performs cooling and heating processes on the food on the food tray together with the cart, the refrigerator is sometimes installed with the legs removed and the main case in close contact with the floor surface to make it easier to take the cart in and out. In such refrigerators without legs, it is impossible to provide a drainage trap in the gap between the main case and the floor surface, so the drainage structure of Patent Document 1 cannot be applied.

[0005] In addition, the direction in which the drain hose leading from the drain trap is pulled out is selected to either the right or left side of the main body case depending on the installation conditions of the refrigerator, such as the position of the drain groove or the position of the wall adjacent to the refrigerator. However, if the direction in which this drain hose is pulled out could be easily changed, the refrigerator would be more convenient to use.

[0006] The present invention has been made with the aim of solving the problems associated with conventional refrigerators as described above, and aims to enable a drain trap to be installed in a refrigerator regardless of whether there is a gap between the main body case and the floor, and to enable the direction in which the drain hose extending from the drain trap and leading outside the refrigerator to be easily switched between right and left. [Means for solving the problem]

[0007] The present invention relates to a cooling cabinet comprising a main case 2 consisting of a rectangular box-shaped insulated body 15 having a front opening 3, a storage cabinet 2A provided inside the main case 2 for storing stored items, an evaporator 9 arranged above the storage cabinet 2A for cooling the interior of the cabinet, a drain pan 23 for receiving drain water W discharged from the evaporator 9, a water receiving pipe 24 extending downward from the drain pan 23, a drain trap 25 connected to the lower end of the water receiving pipe 24, a drain hose 26 connected to the drain trap 25 and led to the outside of the main case 2, and a flow path arrangement structure 27 for assembling the drain trap 25 and the drain hose 26 to the main case 2, and in which the drain water W discharged from the evaporator 9 and received in the drain pan 23 is discharged to the outside of the cabinet via the water receiving pipe 24, the drain trap 25, and the drain hose 26. The heat-insulating box 15 constituting the main body case 2 is composed of an outer box 13, an inner box 12 provided inside the outer box 13 with a required distance between them, and a heat insulating material 14 made of foamed resin filled in the filled space between the boxes 13 and 12. The flow path arrangement structure 27 includes a recessed portion 37 formed partially rearward in the inner box 12 constituting the rear wall 15A of the heat-insulating box 15 and accommodating the drain trap 25, a hose accommodating portion 40 partitioned by a cover plate 38 with a hat-shaped cross section fixed to the front surface of the inner box 12 so as to cross the recessed portion 37 and accommodating the drain hose 26 therein, and a hose hole 41 provided through each of the left and right side walls 15B and 15C of the heat-insulating box 15 facing the left and right ends of the hose accommodating portion 40 and allowing the drain hose 26 to pass through. Cover plate 38 is formed horizontally long from the right end to the left end of inner box 12, and hose housing sections 40B, 40A are formed on both the left and right sides of recessed portion 37. Drain hose 26 connected to drain trap 25 is disposed inside one of the left and right hose housing sections 40B, 40A formed on either side of recessed portion 37, and is led out to the outside of the left and right side surfaces of main body case 2 through hose hole 41.

[0008] The flow path arrangement structure 27 includes recesses 42, 42 formed inwardly in the left and right directions in the outer box 13 of the heat-insulating box body 15 facing the left and right ends of the cover plate 38. A hose hole 41 is formed to connect the recesses 42 and the hose housing part 40. The drain hose 26 is led out to the outside of the left and right side surfaces of the main body case 2 through the hose hole 41 and the recesses 42.

[0009] A vertically long opening 42E is formed in each of the depressions 42 so as to face outward in the left and right directions, and the opening 42E of each of the depressions 42 is covered with a cover member 51. The vertical length of one of the cover members 51A (51) is set shorter than the vertical length of the other of the cover members 51B (51). A short cover member 51A (51) is fixed to the outer surface of the depression 42 on one side from which the drain hose 26 is led out, and a long cover member 51B (51) is fixed to the outer surface of the depression 42 on the other side. An outlet 52 for the drain hose 26 that is not covered by the short cover member 51A (51) is formed at the lower end of the opening 42E of the depression 42 on one side, and the entire opening 42E of the depression 42 on the other side is covered with the long cover member 51B (51). Effect of the Invention

[0010] As in the present invention, when the inner box 12 constituting the rear wall 15A of the insulating box body 15 is partially recessed backward to form a recessed portion 37 and the drain trap 25 is disposed in the recessed portion 37, the drain trap 25 can be installed in the main body case 2 even if, for example, the cooling cabinet does not have legs and there is no gap between the main body case 2 and the floor surface F. In other words, the drain trap 25 can be installed in the main body case 2 regardless of the presence or absence of a gap between the main body case 2 and the floor surface F.

[0011] In addition, as in the present invention, when the hose housing section 40 in which the drain hose 26 is housed is formed inside by the cover plate 38 having a hat-shaped cross section and fixed to the front surface of the inner box 12 so as to cross the recessed portion 37, and the hose housing sections 40B and 40A are formed on both the left and right sides of the recessed portion 37 inside the cover plate 38, the drain hose 26 can be easily drawn out in either the left or right direction by using the common cover plate 38 without using a dedicated member. Also, when the cover plate 38 is fixed to the front surface of the inner box 12, the removal and fixing operations of the cover plate 38 can be carried out from the front side of the interior (storage compartment 2A) of the main body case 2, and further, the installation operation of the drain hose 26 can be carried out from the front side of the interior of the main body case 2. Therefore, even if it becomes necessary to change the lead-out direction of the drain hose 26 depending on the installation situation of the cooling compartment, the change operation can be carried out more easily.

[0012] Furthermore, as in the present invention, when the hose housing portion 40 is defined by the cover plate 38 fixed to the front surface of the inner box 12, it is possible to prevent the thickness dimension in the front-to-rear direction of the insulating material 14 of the insulating box 15 in the hose housing portion from being impaired, compared to a configuration in which the hose housing portion is formed by forming a recess in the rear direction in the inner box 12. Therefore, it is possible to prevent the insulating performance of the insulating box 15 from being reduced due to the formation of the hose housing portion 40.

[0013] When flow path arrangement structure 27 includes recesses 42, 42 formed inwardly to the left and right in outer box 13 of heat-insulating box body 15 facing the left and right ends of cover plate 38, and hose hole 41 is formed to connect recess 42 and hose accommodating section 40, and drain hose 26 is led out to the outside of the left and right side surfaces of main body case 2 via hose hole 41 and recess 42, the bent portion of drain hose 26 led out from hose hole 41 and pointing downward can be disposed within recess 42. This can prevent stress from being applied directly to the bent portion of drain hose 26, thereby preventing drain hose 26 from being damaged.

[0014] Each depression 42 has a vertically long opening 42E facing outward to the left and right, and when opening 42E of each depression 42 is covered with cover member 51, leakage of inside air through hose hole 41 can be prevented. In addition, when short cover member 51A is fixed to the outer surface of depression 42 on one side from which drain hose 26 is led out, and outlet 52 of drain hose 26 that is not covered by short cover member 51A is formed at the lower end, drain hose 26 can be led out of depression 42 through outlet 52 while minimizing the opening area of ​​the portion (outlet 52) ​​of opening 42E of depression 42 that is not covered by cover member 51, so leakage of inside air through outlet 52 can be suppressed. In addition, when a long cover member 51B is fixed to the outer surface of the other side of the recessed portion 42 on which the drain hose 26 is not arranged, it is possible to prevent air inside the storage unit from leaking out through the opening 42E of the recessed portion 42 on the other side.

Food cooked in the kitchen is placed on the tray rack 18 while being housed in each tray 21, and is then housed inside the cooling chamber main body 1 (storage chamber 2A) together with the cart 16 to be cooled.

[0018] 2 and 3, the main body case 2 is provided with a drainage structure 22 that discharges drain water W discharged from the evaporator 9 to the outside of the cabinet. The drainage structure 22 is composed of a drain pan 23 disposed below the evaporator 9, a water receiving pipe 24 extending downward from the drain pan 23, a drain trap 25 connected to the lower end of the water receiving pipe 24, a drain hose 26 connected to the drain trap 25 and led out to the outside of the main body case 2, and a flow path arrangement structure 27 for assembling the drain trap 25 and the drain hose 26 to the main body case 2.

[0019] As shown in Fig. 4, the drain trap 25 includes a box-shaped trap body 29 made of synthetic resin that is connected to the lower part of the drain port 28 at the bottom end of the receiving pipe 24, and a partition wall 30 that divides the inside of the trap body 29. The partition wall 30 divides the water storage chamber 31 in the trap body 29 into a drain chamber 32 on the left side and a trap chamber 33 on the right side. A drain port 34 is opened at a predetermined height in the trap chamber 33, and drain water W that overflows beyond the set water level defined by this drain port 34 is discharged to the outside of the trap body 29. A drain hose 26, which is a flexible pipe having flexibility, is connected to the drain port 34.

[0020] As shown in FIG. 1, the flow path arrangement structure 27 is composed of a recessed portion 37 formed partially rearward in the inner box 12 constituting the rear wall 15A of the insulating box 15 of the main body case 2, in which the drain trap 25 is accommodated, a hose accommodating portion 40 defined by a cover plate 38 having a hat-shaped cross section fixed to the front surface of the inner box 12 so as to cross the recessed portion 37 and in which the drain hose 26 is accommodated, hose holes 41, 41 which are provided in each of the left and right side walls 15B, 15C of the insulating box 15 facing the left and right ends of the hose accommodating portion 40 to allow the drain hose 26 to pass through, and a recessed portion 42 formed in the outer box 13 of the insulating box 15 facing the left and right ends of the cover plate 38, recessed inwardly to the left and right.

[0021] As shown in FIG. 2, the receiving pipe 24 and the recessed portion 37 are formed on the right side of the rear wall 15A of the thermal insulation box 15 (slightly to the right of the center in the left-right direction). The receiving pipe 24 is built into the space filled with the foam insulation material 14 between the inner box 12 and the outer box 13 of the thermal insulation box 15. As shown in FIG. 1 and FIG. 5, the recessed portion 37 is defined by the rear inner surface 37A, the left and right side surfaces 37B and 37B, and the top and bottom surfaces 37C and 37D that constitute the inner box 12, and is formed as a square block-shaped sinkhole having an opening 37E in the front. In FIG. 4 and FIG. 5, the reference numeral 43 denotes a screw for fixing the drain trap 25 to the inner surface 37A of the inner box 12, and the reference numeral 44 denotes a screw for fixing a plate 45 that closes the opening 37E of the recessed portion 37.

[0022] As shown in Fig. 4 and Fig. 5, the cover plate 38 constituting the hose housing 40 is made up of a protruding plate 38A protruding forward, a pair of upper and lower plate portions 38B extending rearward from the upper and lower ends of the protruding plate 38A, and a pair of mounting plate portions 38C bent in the vertical direction from the rear ends of the upper and lower plate portions 38B and 38B and fixed to the inner box 12 of the heat-insulating box body 15 with screws 48, and the three plate portions 38A, 38B, 38C form a hat-shaped cross section. As shown in Fig. 2, the cover plate 38 is fixed to the front surface of the inner box 12 so as to cross the recessed portion 37. The cover plate 38 is formed over the entire length of the storage 2A in the left-right direction from the left end to the right end of the front surface of the inner box 12. As a result, a hose accommodating section 40 is formed over the entire left-right length of the front surface of the inner box 12, partitioned by the inner surface of the bulging section 47 of the cover plate 38 and the front surface of the inner box 12 facing said inner surface. In addition, a right hose accommodating section 40A is formed on the right side across the recessed portion 37, and a left hose accommodating section 40B is formed on the left side across the recessed portion 37.

[0023] As shown in Fig. 6, hose holes 41 are provided in the left and right side walls 15B and 15C of the insulating box 15 facing the left and right ends of the hose housing 40, respectively, and connect the recessed portion 42 and the hose housing 40. Each of the left and right hose holes 41 is formed in a straight hollow cylinder with a uniform diameter dimension in the left-right direction. In the right hose hole 41 where the drain hose 26 is disposed, the gap between the outer peripheral surface of the drain hose 26 and the inner peripheral surface of the hose hole 41 is filled with putty 50. The entire left hose hole 41 where the drain hose 26 is not disposed is also filled with putty 50.

[0024] 6, depressed portion 42 is defined by a rear surface 42A in the left-right direction, front-rear surfaces 42B-42B, and top-bottom surfaces 42C-42D, and is formed as a rectangular block-shaped depressed hole that is long in the up-down direction and has openings 42E on the left and right. The depressed shapes of left and right depressed portions 42 and the opening shape of openings 42E are the same shape.

[0025] Each of the openings 42E of the left and right recesses 42 is sealed by a cover member 51. The vertical length of the right cover member 51A is set shorter than the vertical length of the opening 42E of the recess 42, and an outlet 52 for guiding the drain hose 26 to the outside of the storage unit is formed at the lower end of the opening 42E of the right recess 42. The vertical length of the left cover member 51B is set longer than the vertical length of the opening 42E of the recess 42, and the entire opening 42E of the left recess 42 is covered by the cover member 51B. In Figs. 1 and 6, reference numeral 53 denotes a screw for fixing the cover member 51 to the periphery of the opening 42E of the outer box 13.

[0026] As a result, drain hose 26 connected to drain trap 25 passes through hose housing portion 40 (40A) located to the right of recess 37, hose hole 41, depressed portion 42, and outlet 52, and is led out to the outside of the right side surface of main body case 2 (see FIG. 1). Drain hose 26 is bent at right angles in the portion leading from hose hole 41 to depressed portion 42 and in the portion leading from depressed portion 42 to outlet 52. Therefore, from hose hole 41 to outlet 52, drain hose 26 is bent in a crank-like shape.

[0027] In this embodiment, the drain trap 25 and the drain hose 26 can be assembled to the flow path arrangement structure 27 in the following procedure. At the time of shipment from the factory, the drain trap 25, the drain hose 26, the cover plate 38, the cover member 51, and the like are removed from the main body case 2. When the cooling cabinet is brought into a store or the like and installed at a predetermined location in the store, and the direction in which the drain hose 26 is drawn out is determined, the worker first connects the drain trap 25 to the drain port 28 of the receiving pipe 24 and fixes the drain trap 25 in the recessed portion 37 with a screw 43. Next, after connecting one end of the drain hose 26 to the drain port 34 of the drain trap 25, the drain hose 26 is extended in the left-right direction (rightward in this embodiment) along the front surface of the inner box 12 of the heat-insulating box 15, and the other end of the drain hose 26 is inserted into the hose hole 41 and led out to the outside of the right side surface of the main body case 2 through the recessed portion 42. Next, plate 45 is fixed with screws 44 so as to close opening 37E in front of recess 37. In addition, in right-side hose hole 41, the gap between the outer peripheral surface of drain hose 26 and the inner peripheral surface of hose hole 41 is filled with putty 50, and the entire left-side hose hole 41, in which drain hose 26 is not disposed, is filled with putty 50. Finally, cover plate 38 is fixed with screws 48 so as to cover drain hose 26, and cover members 51, 51 are fixed with screws 53 to the left and right recesses 42, respectively. As described above, flow path arrangement structure 27 is constructed in main body case 2, and drain trap 25 and drain hose 26 can be assembled to flow path arrangement structure 27.

[0028] In addition, if the installation location of the cooling box is changed from the above state and it becomes necessary to change the pull-out direction of the drain hose 26 (to the left), the worker first removes the cover plate 38 and the cover member 51, and removes the putty 50 from the hose hole 41. Next, the plate 45 is removed, and the drain hose 26 is removed from the drain outlet 34. Next, the drain hose 26 is extended to the left, and the drain hose 26 is reconnected to the drain outlet 34, and the other end of the drain hose 26 is inserted into the left hose hole 41, and the drain hose 26 is led out to the outside of the left side surface of the main body case 2 through the left recessed portion 42. Next, the plate 45 is fixed with the screw 44 so as to close the front opening 37E of the recessed portion 37, and the left and right hose holes 41 are filled with the putty 50, and the cover plate 38 is fixed with the screw 48 so as to cover the drain hose 26. Finally, the cover members 51 are fixed to the left and right recessed portions 42, respectively, with the screw 53. By adopting the above-mentioned procedure, the pull-out direction of the drain hose 26 can be changed from right to left.

[0029] As described above, in the cooling cabinet of this embodiment, a recess 37 is partially formed rearward in the inner box 12 that constitutes the rear wall 15A of the insulated box body 15, and the drain trap 25 is arranged in the recess 37. Therefore, even if the cooling cabinet does not have legs and is configured in such a way that there is no gap between the main body case 2 and the floor surface F, the drain trap 25 can be assembled into the main body case 2 without any problems.

[0030] In this embodiment, the cover plate 38 having a hat-shaped cross section is fixed to the front of the inner box 12, and the drain hose 26 is arranged in a horizontally long space partitioned by the bulging portion 47 of the cover plate 38, so that the drain hose 26 can be led out in either the left or right direction without using a dedicated member. Therefore, the drain hose 26 can be easily pulled out in either the left or right direction. In addition, since the installation work of the drain hose 26 can be carried out from the front side of the interior of the main body case 2, even if it becomes necessary to change the lead-out direction of the drain hose 26 depending on the installation situation of the cooling chamber, the change work can be easily carried out.

[0031] Since the drain hose 26 is disposed in the space partitioned by the front surface of the inner box 12 and the bulging portion 47 of the cover plate 38 fixed to the front surface of the inner box 12, it is possible to prevent the front-to-rear thickness dimension of the foamed insulation material 14 of the insulated box 15 at the location where the hose housing portion 40 is formed from being impaired, compared to a configuration in which the inner box 12 is recessed rearward to form a hose housing portion. Therefore, it is possible to prevent the insulation performance of the insulated box 15 from being reduced due to the formation of the hose housing portion 40.

[0032] Depressions 42·42 are formed inwardly to the left and right in the outer box 13 of the insulated box body 15 facing the left and right ends of the cover plate 38, and hose holes 41 are formed to connect each depression 42 to the hose accommodating section 40. This allows the bent portion of the drain hose 26 leading out from the hose hole 41 and heading downward to be positioned within the depression 42. This prevents direct stress from being applied to the bent portion of the drain hose 26, and more reliably prevents the drain hose 26 from being damaged.

[0033] Since the opening 42E of each recess 42 is covered with the cover member 51, it is possible to reliably prevent the air inside the storage compartment from leaking out of the storage compartment through the hose hole 41. In addition, a short cover member 51A is fixed to the outer surface of the recess 42 on one side from which the drain hose 26 is led out, and an outlet 52 for the drain hose 26 that is not covered by the cover member 51A is formed at the lower end of the recess 42. Therefore, while the drain hose 26 is led out of the recess 42 through the outlet 52, the opening area of ​​the part (outlet 52) ​​of the opening 42E of the recess 42 that is not covered by the cover member 51A is minimized, and it is possible to suppress the air inside the storage compartment from leaking out of the outlet 52. In addition, since a long cover member 51B is fixed to the outer surface of the recess 42 on the other side from which the drain hose 26 is not arranged, it is possible to prevent the air inside the storage compartment from leaking out of the opening 42E of the recess 42 on the other side.

[0034] In the above embodiment, an example was shown in which the cooling box of the present invention is applied to a cart-in type cooling box, but the cooling box of the present invention can also be applied to commercial refrigerators and the like. [Explanation of symbols]
