In some embodiments, as shown in connection with fig. 1, 2, and 4, a deicing mechanism 200 for a refrigeration appliance is provided. As shown in fig. 8, the refrigeration device 100 includes a case 110 and an inner container 112, where the inner container 112 is disposed in the case 110. Deicing mechanism 200 includes heating element 210, drain pipe 220, and drain structure 230. The heating element 210 is disposed on an outer wall of the liner 112, and is used for heating a cavity of the liner 112. One end of the drain pipe 220 is connected to the drain port 114 of the liner 112, and the other end of the drain pipe 220 is a drain end. The drain structure 230 is provided on the lower cross member 116 of the tank 110, and the drain end is provided on the drain structure 230.

The deicing mechanism 200 provided in the embodiment of the present disclosure is applied to the refrigeration apparatus 100. The refrigeration device 100 includes a case 110 and a liner 112 disposed within the case 110. The housing 110 also includes a cross member 116 at the bottom. The liner 112 includes a storage compartment. Deicing mechanism 200 includes heating element 210, drain pipe 220, and drain structure 230. The heating elements 210 are distributed on the outer wall of the inner container 112, and the inner container 112 is heated by opening the heating elements 210 to heat the ice cubes in the storage compartment, so as to accelerate the melting of the ice cubes. One end of the drain pipe 220 is connected to the drain port 114 of the liner 112, and the other end of the drain pipe 220 is a drain end. The water after melting the ice cubes in the storage compartment enters the drain pipe 220 through the drain port 114 and is discharged through the drain end. The drain structure 230 is disposed at the cross member 116 at the bottom of the tank 110. By disposing the drain end within the drain structure 230, a container may be placed on the ground below the drain structure 230 to collect water drained from the drain end when de-icing is performed. Therefore, a user can select a large-volume container to receive water, and further, the overflow of ice water can be effectively avoided. In addition, the user does not need to pay attention to the water receiving condition in the deicing process, so that the use experience of the user is improved, and the use safety is also improved.

Alternatively, as shown in connection with fig. 3, 5-7, the drain structure 230 includes a box and a switch structure 240. The cartridge includes a receiving chamber 236 and a through hole 238, and the drain end of the drain pipe 220 extends into the receiving chamber 236 through the through hole 238. The switch structure 240 is disposed on the case, and the switch structure 240 is used for opening or closing the drain end.

In this embodiment, the drain structure 230 includes a receiving chamber 236 for receiving a drain end. The drain structure 230 is provided with a through hole 238 for the drain pipe 220 to pass through. The drain end extends through the through hole 238 into the receiving cavity 236. The opening of the drain end is controlled by the switch structure 240 to drain. Or the water discharge end is closed through the switch structure 240 to avoid water leakage in the water discharge pipe 220, so that the use safety and the operation convenience are improved.

Alternatively, as shown in connection with fig. 3, 6, and 7, the case includes a base 234 and a cover 232. The through hole 238 is formed in the base 234. The cover 232 is detachably connected to the base 234, and the cover 232 can open or close the accommodating chamber 236.

In this embodiment, the cartridge includes a cover 232 and a base 234 that are removably connected. A receiving chamber 236 for receiving the drain end is defined by the cover 232 and the housing 234. When deicing is performed, the cover 232 is opened, and the drain end is exposed to drain water. When deicing is not required, the cover 232 is closed and the drain end is received in the receiving chamber 236. Thus, on one hand, the appearance is neat and beautiful. On the other hand, the cover 232 further blocks the overflow of the ice water, thereby improving the use safety.

Optionally, as shown in connection with fig. 3, 6, and 7, the switch structure 240 includes a first protrusion 242. The first protrusion 242 is disposed in the accommodating cavity 236 and located at one side of the through hole 238. A first gap 244 is formed between the end of the first protrusion 242 and the wall of the receiving chamber, and the drain end is clamped in the first gap 244. Wherein the width of the first gap 244 is smaller than the pipe diameter of the drain pipe 220.

In this embodiment, the switch structure 240 includes a first protrusion 242. The first protrusion 242 includes a root and an end. The end portion extends toward the side away from the through hole 238 in accordance with the connection with the chamber wall of the accommodating chamber 236. And a first gap 244 is provided between the end and the inner wall of the receiving chamber 236, and the width of the first gap 244 is smaller than the pipe diameter of the drain pipe 220. In this way, in the case that deicing is not needed, the drain pipe 220 is clamped in the first gap 244, so that the drain pipe 220 deforms, and the function of closing the drain end is achieved.

Optionally, as shown in fig. 3, 6 and 7, the switch structure 240 further includes a second protrusion 246 disposed in the accommodating cavity 236 and spaced from the first protrusion 242, the first protrusion 242 being located between the through hole 238 and the second protrusion 246, and a second gap 248 being provided between the first protrusion 242 and the second protrusion 246; wherein the width of the second gap 248 between the first projection 242 and the second projection 246 is smaller than the pipe diameter of the drain pipe 220.

In this embodiment, the switch structure 240 further includes a second protrusion 246. The second protrusion 246 is spaced apart from the first protrusion 242 in the accommodating chamber 236, and a second gap 248 is provided between the first protrusion 242 and the second protrusion 246. And, the first protrusion 242 is located in the middle of the through hole 238 and the second protrusion 246. Further, a width of the second gap 248 between the first projection 242 and the second pathway is less than a pipe diameter of the drain pipe 220. Thus, in the event that deicing is not required, drain tube 220 extends into receiving chamber 236 through throughbore 238, with the end of first projection 242 being clamped against the chamber wall of receiving chamber 236, the drain end extending toward the space between first projection 242 and second projection 246. In this way, the end of the first protrusion 242 of the drain pipe 220 is bent, and the drain pipe 220 is deformed by the bending, so that the flow of water in the drain pipe 220 can be blocked. The bent drain pipe 220 is clamped by the first protrusion 242 and the second protrusion 246, so that the drain end is limited by the first protrusion 242 and the second protrusion 246, the drain end is fixed and cannot rotate, closing and fixing of the drain end are achieved, and overflow of ice water is avoided. In the case of deicing, the user only needs to remove the drain pipe 220 from the first protrusion 242 and the second protrusion 246 and then from the first gap 244 between the first protrusion 242 and the wall of the receiving chamber 236, thereby draining water.

Further, a container is placed on the ground, and the drainage end is placed in the container, so that the collection of the ice water is completed. The deicing mechanism 200 is simple in overall structure, easy to operate and convenient and safe to use.

Alternatively, as shown in fig. 3, 6 and 7, the switch structure 240 includes a first protrusion 242 and a second protrusion 246 that are disposed at intervals, the first protrusion 242 is disposed on the base 234, and the second protrusion 246 is disposed on the cover 232. Wherein, when the cover 232 is in the closed state, a second gap 248 is provided between the first protrusion 242 and the second protrusion 246, and the width of the first gap 244 between the first protrusion 242 and the cover 232 is smaller than the pipe diameter of the drain pipe 220, and the width of the second gap 248 is smaller than the pipe diameter of the drain pipe 220.

In this embodiment, the switch structure 240 includes a first protrusion 242 and a second protrusion 246. The first protrusions 242 and the second protrusions 246 are spaced apart. The first protrusion 242 is disposed on the base 234, and the second protrusion 246 is disposed on the cover 232. The first protrusion 242 is located on the same wall of the receiving cavity 236 as the through hole 238. The first protrusion 242 extends toward one side of the cover 232. The second projection 246 extends toward the sidewall where the through hole 238 is located. By disposing the first projection 242 and the second projection 246 on the base 234 and the cover 232 separately, the taking out of the receiver drain pipe 220 of the drain pipe 220 is facilitated.

Specifically, in the case where deicing is not required, after the drain pipe 220 is clamped in the first gap 244 between the first protrusion 242 and the wall of the accommodating chamber 236, the cover 232 is covered, and the second protrusion 246 on the cover 232 applies a pressing force to the drain pipe 220, so that the drain pipe 220 is clamped in the second gap 248 between the first protrusion 242 and the second protrusion 246.

In the event that deicing is desired, the cover 232 is opened and the second projection 246 releases the drain pipe 220, the user simply removes the drain pipe 220 from the first gap 244 between the first projection 242 and the receiving chamber 236.

Optionally, the ends of the first and second protrusions 242 and 246 are tapered to promote tightness of the clamp to the drain pipe 220.

Alternatively, as shown in fig. 6 and 7, the first protrusion 242 includes a first inclined surface and a second inclined surface, the first inclined surface is located at one side of the through hole 238, the second inclined surface is located at one side of the second protrusion 246, and an included angle between the first inclined surface and the second inclined surface is an acute angle. In this way, the deformation of the drain pipe 220 with a bending angle greater than 90 ° can be caused by the extrusion of the first protrusion 242 and the second protrusion 246, and the deformation can effectively prevent water in the drain pipe 220 from flowing out.

Optionally, the cover 232 is rotatably connected to the base 234, and the cover 232 rotates relative to the base 234 to open or close the accommodating cavity 236.

Optionally, the cover 232 includes a catch 250, the catch 250 facing one side of the base 234. The base 234 is provided with a clamping groove 252 adapted to the buckle 250. The cover 232 is detachably connected with the base 234 by the clamping connection of the clamping buckle 250 and the clamping groove 252.

Optionally, the wall of the accommodating cavity 236 where the through hole 238 is located corresponds to the cover 232. Thus, when the cover 232 is opened to drain water, the drain pipe 220 can directly extend out of the accommodating cavity 236, so that the drain pipe is convenient to be matched with an external container, and water can be smoothly drained, and water leakage is avoided.

Optionally, the cover 232 and the base 234 are connected by a flexible rib, and the structure of the buckle 250 and the slot 252 is combined, so that the drain structure 230 can be opened and closed for multiple times.

Optionally, the drainage structure 230 adopts an integrated structure, and is integrally installed at the bottom of the refrigerator after the beam 116 corresponds to the positioning hole, so that other parts do not need to be assembled, and the assembly difficulty is reduced. Meanwhile, the first protrusion 242 in the seat 234 may press the drain pipe 220 to prevent the residual water in the drain pipe 220 from leaking in the condition that the drain structure 230 is closed.

Alternatively, as shown in connection with fig. 2, the drain pipe 220 includes a first pipe body 222 and a second pipe body 224. One end of the first pipe 222 communicates with the drain port 114. One end of the second pipe 224 is connected to the other end of the first pipe 222, and the other end of the second pipe 224 is disposed in the drain structure 230. The second tube 224 is a hose, and the first tube 222 and the second tube 224 are spaced apart from the liner 112.

In this embodiment, drain pipe 220 includes a first pipe body 222 and a second pipe body 224. Two ends of the first pipe body 222 are respectively communicated with one end of the water outlet 114 and one end of the second pipe body 224. The other end of the second tube 224 extends into the receiving cavity 236. The second pipe 224 is a hose, and the hose is used to bend, so that the water draining end can be bent to avoid water flowing out of the water draining pipe 220. Through all carrying out the interval setting with first body 222 and second body 224 with the inner bag 112, and then avoid the supercooling to lead to the water in the drain pipe 220 to ice, promote the smoothness nature of drainage.

Optionally, the first pipe body 222 is a hard pipe. The first pipe 222 communicates with the water receiving port of the liner 112. By adopting the hard pipe, the distance between the hard pipe and the inner container 112 of the refrigerating room and the freezing room can be kept, so that too-near icing is prevented, and the stability of drainage is improved.

Optionally, as shown in connection with fig. 1, the refrigeration unit 100 further includes an evaporator coil 118 for cooling the liner 112, and the heating element 210 includes a heating tube. The heating pipe is disposed on the outer side wall of the inner container 112, the arrangement mode of the heating pipe is the same as that of the evaporator coil 118, and the heating pipe is disposed adjacent to the evaporator coil 118.

In this embodiment, the heating tubes are arranged in an arrangement of the evaporator coils 118, with the heating tubes being disposed adjacent the evaporator coils 118, considering that the attachment of the evaporator coils 118 is the most ice prone area. In this way, the efficiency of deicing can be improved.

Optionally, as shown in connection with fig. 2, the refrigeration appliance 100 also includes a control button 212. The control button 212 is electrically connected to the heating element 210 for switching the heating element 210 on or off.

In this embodiment, the heating element 210 is electrically connected by providing a control button 212. In case deicing is required, the heating wire is turned on by means of the control button 212. When deicing is completed, the heating wire is turned off by the control button 212. Simple structure, easy operation promotes user's use and experiences.

Specifically, in normal use of the refrigeration apparatus 100, the heating element 210 is not operated and the evaporator is operated in normal refrigeration. When deicing is carried out, the heating element 210 is controlled to be started by the button, and the heating element 210 starts to work, so that the heating element 210 is consistent with the layout of the evaporator coil, namely, the heating element is heated at the position most easy to freeze, and quick melting deicing can be realized.

In some embodiments, as shown in connection with fig. 1 and 8, there is provided a refrigeration apparatus 100 comprising: the case 110 includes an inner container 112; and the deicing mechanism 200 for the refrigeration apparatus 100 according to any one of the embodiments described above, the heating element 210 is provided to the inner container 112, and the drainage structure 230 is provided to the cross member 116 at the bottom of the tank 110.

The heating elements 210 are distributed on the outer wall of the inner container 112, and the inner container 112 is heated by opening the heating elements 210 to heat the ice cubes in the storage compartment, so as to accelerate the melting of the ice cubes. One end of the drain pipe 220 is connected to the drain port 114 of the liner 112, and the other end of the drain pipe 220 is a drain end. The water after melting the ice cubes in the storage compartment enters the drain pipe 220 through the drain port 114 and is discharged through the drain end.
