Description

  The present invention relates to a refrigerator provided with a box that requires drain water to be discharged.

  As a conventional refrigerator, for example, “a machine room in which a compressor or the like is provided by a drain pipe provided in a heat insulating wall of a refrigerator body for generating water when melting frost attached to a cooler provided in the refrigerator body. In this case, there has been proposed a structure in which a space portion whose lower portion opens into the machine chamber is provided around the drain pipe (see, for example, Patent Document 1).

JP-A-6-82149 (Claim 1, FIG. 1)

  The drain drainage path of the conventional refrigerator is embedded and attached to the heat insulating material of the refrigerator. For this reason, moisture may enter the interior of the insulation from gaps that may be generated when the seal of the drainage path of the drainage drainage path is incomplete due to problems such as poor assembly or when the drainage parts in the insulation are defective. There are cases where a route to enter can be made. In such a case, frost growth starts from the inside of the heat insulating material that has flowed around the water, and eventually it becomes so large that it cannot be melted by a defrosting heater etc., leading to a problem that blocks the drainage path. is there. Also, when the refrigerator is assembled, the drainage path may be clogged due to the fall of fine parts or the fall of fine food waste.

  The present invention has been made to solve the above-described problems, and a first object is to eliminate the infiltration of water into the heat insulating material and the occurrence of problems such as ice blocking the drainage path. The second purpose is to replace the drainage drainage path even if there is a situation where the drainage drainage path is clogged due to a problem such as dropping of parts during assembly. An object of the present invention is to provide a refrigerator that can be implemented even after the refrigerator is assembled as a product.

  The refrigerator according to the present invention includes a drain pipe that is disposed below the cooler and discharges drain water, and a drain passage that is formed in a through hole provided in the wall of the refrigerator body and through which the drain pipe is inserted. And the drainage path and the drainage pipe are configured as separate parts, and the drainage pipe is passed through the drainage path seamlessly.

  In the refrigerator of the present invention, drain water is not leaked into the heat insulating material by installing the drain pipe in the cabinet, and the drain pipe is configured as a separate part even when passing through the heat insulating material. Since drain water is passed through the evaporation tray through the drainage path, the drain water does not leak into the heat insulating material. Also, since the drain pipe is not embedded in the heat insulating material, it is possible to remove and replace only the drain pipe for service etc., and even if the drain pipe is clogged due to some trouble, the product itself is not replaced and the serviceability is improved To do.

Embodiment 1 FIG.
Embodiment 1 of the present invention will be described below with reference to the drawings.
FIG. 1 is a side sectional view of the refrigerator according to the first embodiment, FIG. 2 is a sectional side view of the main portion of the refrigerator according to the first embodiment, and FIG. 3 is a front view of the main portion viewed from the refrigerator according to the first embodiment. is there.

  In FIG. 1, a refrigerator main body is formed by sandwiching a heat insulating material 35 using urethane foam or the like in a space formed by an inner box 34, a steel plate outer plate 33, a back plate 37 and a bottom plate 38. Further, the inside of the refrigerator is divided by partitions 66, 67, 68 to divide the inside of the refrigerator. In this embodiment, the uppermost room is a refrigerator compartment 15, the second stage is a freezer room 16, the third stage is a freezer room 17, and the lowermost stage is a vegetable room 18. Further, doors 62, 63, 64, 65 are prepared in the respective rooms, and the space between the main body and the door is sealed with a gasket 61, thereby providing an internal temperature environment that is blocked from outside air. In the refrigerator compartment 15, the storage performance is improved by installing a storage door pocket 51 on the door side and a shelf 52 on the main body side.

  In addition, a cooler 22 is installed to cool the inside of the refrigerator, and a cold air agitating fan 21 is installed to circulate the cold air cooled by the cooler 22, and the refrigerator compartment 15 is provided for the purpose of efficient circulation. A cold air duct 30 is disposed on the side, and a cold air duct 31 is disposed below the freezer compartment 16. Moreover, frost adheres to the cooler 22 by the circulating air in the refrigerator as time passes, and the cooling capacity of the cooler 22 is deteriorated. In order to eliminate the deterioration of the cooling capacity, for example, about once a day, the frost in the cooler 22 is melted by the heat generated by the defrosting heater 23 provided at the lower part of the cooler 22. At that time, if the water generated by the defrosting falls directly to the defrosting heater 23, evaporating sound is generated and it may be considered abnormal to the refrigerator user. Therefore, a heater cover 24 is installed on the top of the defrosting heater 23 to remove the defrosting. The defrosting water is prevented from falling directly on the defrosting heater 23. The water generated by defrosting falls down and is drained, and the mechanism at that time will be described with reference to FIG.

  FIG. 4 is a configuration diagram of the partition 68. The partition 68 has a function of partitioning the freezer compartment 17 and the vegetable compartment 18, collecting drain water from the cooler 22, collecting the water, and discharging it to the drain pipe 25. The partition 68 is configured by sandwiching a heat insulating material 68c such as styrene between a partition upper part 68a provided with a heater holding part a and a cooler holding part a and a partition lower part 68b. The drain water generated by the defrosting is collected by a drain water receiving portion 68d having a circular opening portion downward at a part of the partition upper portion 68a and poured into the drain pipe 25. The drain pipe 25 is disposed under the partition 68 and passes through the vegetable compartment 18. At that time, the position of the drainage pipe 25 in the vegetable compartment 18 is fixed by the concave shape provided in the inner box 34.

Next, a mode in which the drain pipe 25 passes through the inside of the heat insulating material will be described with reference to FIGS. 2 and 3.
A through hole is formed on the lower back side of the vegetable compartment 18, and a concave shape is provided in the inner box 34 at that portion, and a drainage path 26 is attached so as to fit into the concave portion. The drainage path 26 is screwed to the inner box 34 from the heat insulating material side. Further, the embossed shape for fixing the drainage passage 26 to the fixed screw fits into the concave shape of the inner box 34, so that it does not protrude from the inner surface of the warehouse. The drainage path 26 extends to the top of the evaporation tray 28 after passing through the heat insulating material 35. A drainage path 27 that is paired with the drainage path 26 is attached to the bottom plate 38 with screws, and the drainage path 27 is provided outside the main body so as to cover the drainage path 26 after passing through the heat insulating material 35. It has been. An elastic member 70 and an elastic member 71 are prepared in the vicinity of the opening of the drainage passages 26 and 27 to the heat insulating material 35, and the drainage passage 26 and the drainage passage 27, the inner box 34, and the bottom plate 38. Water is prevented from entering the gap formed between them or the heat insulating material 35.

  By fitting the convex portion of the drainage path 26 into the end surface of the drainage path 27 on the compressor side, the projection allowance dimension to the evaporation tray 28 is fixed. The drainage path of the drain is fixed by passing the drainage pipe 25 to the path passing through the heat insulating material constituted by the drainage path 26 and the drainage path 27, so that the drainage path of the drain does not form a joint inside the heat insulating material, and is an evaporating tray with one component configuration. Drainage up to 28 is possible. The drainage water stored in the evaporation tray 28 is evaporated by immersing the high-temperature and high-pressure discharge pipe 47 from the compressor 19. The drainage path 26 and the drainage path 27 constitute a water distribution path of the present invention, the drainage path 26 constitutes a first drainage path pipe, and the drainage path 27 constitutes a second drainage path pipe.

  In the first embodiment, since the drain pipe 25 itself can pass through the heat insulating material 35 without a seam by using such a configuration, the drain water does not leak into the heat insulating material. Also, if the drain pipe 25 itself is defective or if service replacement is necessary due to the fall of some parts, etc., the drain pipe 25 is installed independently from the heat insulating material 35. Only the drainage pipe 25 can be replaced without being replaced and discarded, and serviceability is improved.

Embodiment 2. FIG.
FIG. 5 is a side sectional view showing a main part of a second embodiment of the present invention, and FIG. 6 is a front view of the main part showing a second embodiment of the present invention.
In the first embodiment, when the drain pipe 25 passes through the heat insulating material, a tunnel (drain path) constituted by two parts, a drain path (inside the warehouse) 26 and a drain path (compressor side) 27, is used as a drain path. The drainage pipe 25 was configured to drain drainage to the compressor side by passing through. In the second embodiment, an inner box drainage path 29 formed by molding a part of the inner box 34 is used as a drainage path corresponding to the drainage path 26 (inside the warehouse). The inner box drainage path 29 and the drainage path 27 constitute the drainage path of the present invention, and the inner box drainage path 29 constitutes the first drainage path pipe.

  According to the second embodiment, fewer components are required for the drainage path than in the first embodiment, so that it is possible to reduce component costs and assembly costs. However, when the entire refrigerator is large and therefore the entire inner box is large, from the viewpoint of the moldability of the inner box 34, the moldability deteriorates due to the formation of the drainage passage 29, so the molding cost of the single inner box increases. In that case, the cost of reducing the drainage path 26 and the cost of the molding cycle of the inner box 34 may be compared, and the one with lower cost may be adopted.
