Abstract
Description
Technical Field
[0001] This application relates to the field of refrigeration appliances. Background Art
[0002] Generally speaking, existing refrigeration appliances are provided with a storage chamber. During long-term use, condensed water will accumulate in the storage chamber. The condensed water is discharged outside the storage chamber through a drainage assembly, usually into a water receiving tray in the mechanical chamber. The water receiving tray can evaporate the condensed water into the external atmosphere. When there is a certain distance between the drainage assembly and the water receiving tray, the water flowing out of the drainage assembly may splash out of the water receiving tray. The existing technical solutions usually attach a corrugated pipe at the drainage outlet to guide the water to a preset position, which will increase the cost and assembly complexity of the product. Summary of the Invention
[0003] An object of this application is to provide an improved refrigeration appliance for at least one of the above technical problems.
[0004] The technical solution of this application is a refrigeration appliance, including: an inner shell that defines at least one storage chamber, and a drainage assembly that defines a drainage channel for discharging the water in the storage chamber outside the storage chamber.
[0005] Wherein, the drainage assembly includes a guiding portion that is located in the drainage channel and protrudes from the inner wall of the drainage channel to guide the water flow to a preset position.
[0006] It should be noted that during the long-term use of the refrigeration appliance, water will accumulate in the storage chamber. If the temperature is too low, there may be ice slag. The "water" mentioned in the above "for discharging the water in the storage chamber outside the storage chamber" includes water or ice slag. The "water" mentioned in other places in this article also includes water or ice slag.
[0007] In the solution of this application, on the one hand, by providing a guiding portion in the drainage channel, it is convenient to guide the water or the formed ice slag to a preset position, such as the water receiving tray in the mechanical chamber, so as to prevent the water flowing out of the drainage channel from splashing or flying out of the preset position, especially splashing out of the water receiving tray in the mechanical chamber and affecting the use or lifespan of other electrical components in the mechanical chamber. On the other hand, this application does not require additional corrugated pipes or other water conduits for diversion, has a simple structure, and reduces the cost and assembly complexity of the product.
[0008] In an embodiment of this application, the extending direction of the guiding portion is the same as the extending direction of the drainage channel.
[0009] In an embodiment of this application, the guiding portion is provided on the inner wall of the drain pipe and protrudes towards the central axis direction of the drainage channel.
[0010] In one embodiment of the present application, the guiding portion is integrally formed with the drain pipe. Thus, the structure is simple, which is conducive to reducing the product cost.
[0011] In one embodiment of the present application, the distance that the guiding portion extends from the inner wall towards the central axis direction of the drainage channel ranges from 1 mm to 2 mm.
[0012] In one embodiment of the present application, along the direction from the inlet of the drainage channel to the outlet of the drainage channel, the dimension D of the guiding portion in the circumferential direction of the drainage channel gradually increases. This is conducive to the water flowing downward along the vertical direction of the outlet of the drainage channel, reducing the possibility of the water splashing out of the preset position.
[0013] In one embodiment of the present application, the difference between the maximum dimension and the minimum dimension of the dimension D is not greater than 2 mm.
[0014] In one embodiment of the present application, the guiding portion includes a first end and a second end along the direction from the inlet of the drainage channel to the outlet of the drainage channel, and the second end is flush with the outlet of the drainage channel. This prevents the water from splashing in different directions at the outlet of the drainage assembly, thereby improving the water guiding performance of the drainage assembly.
[0015] In one embodiment of the present application, the guiding portion includes a first end and a second end along the direction from the inlet of the drainage channel to the outlet of the drainage channel, and the first end has a first distance from the inlet. Since the temperature in some storage rooms is below zero, when the drainage assembly is installed on such storage rooms, the water at the inlet of the drainage channel is likely to form ice slag. If the guiding portion is arranged at the inlet, the drainage channel may be blocked. Therefore, a certain distance is provided between the guiding portion and the inlet of the drainage channel, which is conducive to drainage and prevents the occurrence of ice slag blockage.
[0016] In one embodiment of the present application, the first distance is greater than one-third of the total length of the entire drainage channel.
[0017] In one embodiment of the present application, the guiding portion includes a first end and a second end along the direction from the inlet of the drainage channel to the outlet of the drainage channel, and the first end includes an inclined portion, and the inclined portion is configured such that the degree of protruding from the inner wall towards the outlet direction gradually increases starting from the inner wall. On the one hand, this is conducive to guiding the water to drain out of the drainage channel; on the other hand, when the temperature at the inlet of the drainage assembly is relatively low and ice slag appears, the inclined portion is conducive to the discharge of the ice slag and prevents the occurrence of blockage.
[0018] In one embodiment of the present application, there are a plurality of guiding portions, and the plurality of guiding portions are spaced apart in the circumferential direction of the drainage channel.
[0019] In one embodiment of the present application, the drain pipe has at least 4 of the guiding parts. If the number of the guiding parts is less than 4, the guiding effect on the water flow in the drainage channel is weak. Therefore, setting 4 or more guiding parts in the drainage channel is beneficial to improving the guiding performance of the guiding parts for water.
[0020] In one embodiment of the present application, the guiding parts are arranged at equal intervals in the circumferential direction of the drainage channel. This is beneficial to controlling the drainage direction and improving the water guiding performance of the drainage assembly.
[0021] In one embodiment of the present application, the included angle α formed by the directions of two adjacent guiding parts pointing to the central axis direction of the drainage channel is not greater than 90 degrees.
[0022] In one embodiment of the present application, it includes a machine room, the machine room includes a water receiving tray and a machine room wall pointing to the storage room, a heat insulation member is provided between the storage room and the machine room wall, and the drainage assembly is used to guide water from the storage room through the heat insulation member and through the machine room wall to the water receiving tray.

Detailed Description of the Embodiments
[0030] To further understand the purpose, structure, features, and functions of this application, the following is a detailed description in conjunction with embodiments.
[0031] In the description of this application, it should be understood that the orientation or positional relationships indicated by terms such as "upper", "lower", "front", "rear", "height", "lateral", "horizontal", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation.
[0032] The refrigeration appliances described in the embodiments of this application may include refrigerators, freezers, cold storage cabinets, etc. Figure 1 Taking a multi-door refrigerator as an example for exemplary display, in actual applications, the structure of this embodiment can also be applied to other types of refrigeration appliances 1, such as multi-door refrigerators, single-door refrigerators, freezers, etc.
[0033] As Figure 1 As shown, the refrigeration appliance 100 includes an inner shell 1, and the inner shell 1 defines at least one storage compartment 11. The refrigeration appliance 100 further includes an outer shell 5, and the outer shell 5 is formed on the outside of the refrigeration appliance 100. An interval space is formed between the inner shell 1 and the outer shell 5, and a heat insulation member 4 is disposed in the interval space. The heat insulation member 4 is usually formed by foaming a foaming material, for example, using polyurethane foam as the heat insulation member.
[0034] The refrigeration appliance 100 includes a machinery compartment 3, and a compressor 36, a condenser (not shown), and a water receiving tray 31 are disposed in the machinery compartment 3. In an embodiment of this application, the machinery compartment 3 is located at the rear lower part of the storage compartment 11, and the water receiving tray 31 is located above the compressor 31.
[0035] As Figures 1 to 5 As shown, the machinery compartment 3 includes a machinery compartment wall 32 pointing to the storage compartment 11, and a heat insulation member 4 is disposed between the storage compartment 11 and the machinery compartment wall 32.
[0036] Generally, the cold air used to store items in the storage compartment 11 undergoes a refrigeration cycle through the cold air dissipated by an evaporator (not shown). During the heat exchange process, frost or ice crystals will be generated on the wall of the storage compartment 11 or the evaporator (not shown). The refrigeration appliance 100 is provided with a defrosting heater (not shown), so that the frost or ice crystals on the wall of the storage compartment 11 or the evaporator (not shown) turn into water. The formed water needs to be discharged from the storage compartment. Therefore, a drainage assembly 2 is provided in the refrigeration appliance 100.
[0037] Specifically, the drainage component guides water from the storage room through the heat insulation component area and through the mechanical room wall to the water receiving tray in the mechanical room. When the drainage component guides water outside the storage room, especially into the mechanical room, the water led out from the drainage component may splash out of the water receiving tray, thus affecting the use of other components in the mechanical room. In the prior art solutions, the discharge component will attach accessories such as corrugated pipes to guide the water into the water receiving tray to prevent the water from splashing out of the water receiving tray. In this way, the product cost and assembly complexity are increased.
[0038] In order to guide the water to drain out of the drainage component and prevent the water from splashing in different directions at the outlet of the drainage component, the drainage component 2 includes a guiding part 22. Specifically, the drainage component 2 defines a drainage channel 21, and the guiding part 22 is located in the drainage channel 21 and protrudes from the inner wall 23 of the drainage component 2.
[0039] As Figures 1 to 2 shown, the drainage component 2 includes a drain pipe wall 24, and the drain pipe wall 24 defines an inlet 211 of the drainage component 2 and an outlet 212 of the drainage component 2. The drain pipe wall 24 includes an inner wall 23 on the side of the drainage channel 21. The guiding part 22 is arranged on the inner wall 23 of the drain pipe wall 24 and protrudes towards the central axis direction of the drainage channel 21. Specifically, the distance that the guiding part 22 extends from the inner wall 23 towards the central axis direction of the drainage channel 21 is 1 mm to 2 mm.
[0040] In an embodiment of the present application, the guiding part 22 is integrally formed with the drainage component 2. Specifically, the guiding part 22 is integrally formed with the drain pipe wall 24. In other embodiments, the guiding part 22 can be connected to the drainage component 2 by other means, such as by an adhesive.
[0041] The extending direction of the guiding part 22 is the same as the extending direction of the drainage channel 21. In the embodiment of the present application, the guiding part 22 is configured to extend vertically along the extending direction of the drainage channel 21. In other embodiments, the guiding part 22 can extend in a curved shape along the extending direction of the drainage channel 21.
[0042] As Figure 2 shown, the guiding part 22 includes a first end 221 and a second end 222 in the direction from the inlet 211 to the outlet 212 of the drainage component 2.
[0043] The first end 221 has a certain distance from the inlet 211. Specifically, this distance is greater than one-third of the total length of the entire drainage channel 21. The drainage assembly 2 is connected to the storage chamber 11, and the temperature of the storage chamber 11 is relatively low. Especially when the temperature of the storage chamber 11 is below zero degrees Celsius, the temperature at the inlet of the drainage assembly will also be relatively low. It is possible that ice slag may flow into the inlet of the drainage assembly. If the guiding portion is close to the inlet, ice slag may be blocked at the inlet. Therefore, the first end 221 of the guiding portion 22 has a certain distance from the inlet 211.
[0044] As Figure 5 shown, the first end 221 of the guiding portion 22 includes an inclined portion 223, and the inclined portion 223 is configured such that the degree of protruding from the inner wall 23 towards the outlet 212 of the drainage channel 21 gradually increases starting from the inner wall 23. Specifically, the inclined portion 223 includes a first curved surface 2231, an inclined surface 2232 connected to the first curved surface 2231, and a second curved surface 2233 connected to the inclined surface 2232. The first curved surface 2231 starts from the inner wall 23 and protrudes towards the outlet 212 of the drainage channel 21. The inclined surface 2232 is connected to the first curved surface 2231 and continues to extend obliquely towards the outlet 212 of the drainage channel 21. The second curved surface 2233 is connected to the inclined surface 2232 and protrudes to the greatest extent towards the outlet 212 of the drainage assembly. Thus, the first curved surface 2231, the inclined surface 2232, and the second curved surface 2233 form a smooth and continuous inclined portion 223, which is beneficial to improving the guiding performance of the water or ice slag flowing out of the storage chamber.
[0045] The guiding portion 22 includes a second end 222, and the second end 222 is flush with the outlet 212 of the drainage assembly. This prevents water from splashing in different directions at the outlet of the drainage assembly, thereby improving the water guiding performance of the drainage assembly.
[0046] As Figure 4 shown, the drainage assembly 2 includes a plurality of guiding portions 22, and the drainage assembly 2 has at least 4 guiding portions 22. In an embodiment of the present application, the drainage assembly 2 has 4 guiding portions 22. In other embodiments, 5 or more guiding portions 22 can be provided according to requirements.
[0047] The plurality of guiding portions 22 are arranged at intervals on the circumference of the drainage channel 21. Specifically, the guiding portions 22 are arranged at equal intervals in the circumferential direction of the drainage channel 21.
[0048] The included angle α formed by two adjacent guiding portions 22 pointing in the direction of the central axis of the drainage channel 21 is not greater than 90 degrees. In an embodiment of the present application, the included angle α is 90 degrees.
[0049] As Figure 5 shown, along the direction from the inlet of the drainage assembly to the outlet of the drainage assembly, the dimension D of the guiding portion 22 in the circumferential direction of the drainage channel gradually increases.
[0050] In an embodiment of the present application, the guiding portion 22 is configured as a rib extending along the direction of the drainage channel 21. The guiding portion 22 includes two opposite first walls 224, a second wall 226 flush with the outlet 212 of the drainage assembly, and a third wall 225 connecting the first wall 224 and the second wall 226. The third wall 225 extends along the circumferential direction of the drainage channel 21 and the extended dimension is D. From the inlet 211 of the drainage assembly to the outlet 212 of the drainage assembly, the dimension D of the third wall 225 gradually increases, and the difference between the maximum dimension and the minimum dimension of the dimension D is not greater than 2 mm. In an embodiment of the present application, the dimension D increases from 1.9 mm to 2.3 mm.
[0051] In an embodiment of the present application, the guiding portion 22 is configured as a continuous rib. In other embodiments, the guiding portion may be in a discontinuous convex shape.
[0052] Combined with Figures 1 to 5 The various embodiments of the individual components described can be combined with each other in any given manner to achieve the advantages of the present application.
[0053] The present application has been described by the above related embodiments. However, the above embodiments are only examples for implementing the present application. It must be pointed out that the disclosed embodiments do not limit the scope of the present application. On the contrary, changes and modifications made without departing from the spirit and scope of the present application fall within the scope of patent protection of the present application.
