Referring to fig. 2 and 3, fig. 2 is a schematic view illustrating a first structure of an ice making device according to an embodiment of the present disclosure, and fig. 3 is a schematic view illustrating an exploded structure of the ice making device shown in fig. 2. The ice-making device 20 includes an ice-making assembly 22 and a water intake assembly 24. The water inlet assembly 24 includes a first bracket 242, a connection pipe 244, and an inlet pipe 246. The first supporter 242 includes a body 2421 and a first protrusion 2422 provided on the body 2421, and the first supporter 242 is provided with a first through hole 2422a penetrating the body 2421 and the first protrusion 2422 in the first direction X. The connection pipe 244 is sleeved on the first protrusion 2422, and the connection pipe 244 communicates with the first through hole 2422 a. The water inlet pipe 246 is perforated in the first through hole 2422a, and the water inlet pipe 246 communicates with the connection pipe 244 so that water flows into the ice making assembly 22 through the water inlet pipe 246 and the connection pipe 244. Here, the first direction X may be understood as a direction from the first bracket 242 toward the ice making assembly 22, that is, an extending direction of the first protrusion 2422 from the body 2421 toward the ice making assembly 22. The water inlet assembly 24 is simply assembled and the water inlet assembly 24 is conveniently assembled and disassembled by sleeving the connecting pipe 244 on the first protrusion 2422 of the first bracket 242, penetrating the water inlet pipe 246 on the first protrusion 2422 of the first bracket 242 and communicating with the connecting pipe 244, so that the problem that the water inlet assembly of the conventional ice making device is complicated to assemble is solved.

In order to more clearly describe the ice making device 20 provided in the embodiment of the present application, the water inlet assembly 24 and the ice making assembly 22 will be described below with reference to the accompanying drawings.

For example, referring to fig. 4 to 6 in combination with fig. 1, fig. 4 is a second structural schematic diagram of the ice making device shown in fig. 2, fig. 5 is a first cross-sectional schematic diagram of the ice making device shown in fig. 4 along a direction a-a, and fig. 6 is an enlarged structural schematic diagram of a part B of the ice making device shown in fig. 5. The first bracket 242 is used to carry the ice making assembly 22, and the first bracket 242 is also used to connect the water inlet pipe 246 so that the water inlet pipe 246 can provide a passage for water to the ice making assembly 22 through the first bracket 242. The body 2421 of the first support 242 has a square sheet cube structure, and the body 2421 is connected to two hanging lugs, which can be conveniently connected to the door 10. To reinforce the strength of the first bracket 242, a reinforcing plate may be provided at a side of the body 2421 thereof. The first bracket 242 further includes a first protrusion 2422 disposed on the body 2421 of the first bracket 242, and the first protrusion 2422 is used for connecting with the connection pipe 244. Holes, slots, etc. may also be provided in first support 242 to facilitate mating with other components. For example, the first bracket 242 of the embodiment of the present application is provided with a first through-hole 2422a for fitting the water inlet pipe 246 and the connection pipe 244 in the first direction X. The first through hole 2422a may have a circular shape, a square shape, an irregular shape, and the like, and the first through hole 2422a is exemplified as a circular hole in the embodiment of the present application.

The connecting tube 244 may be made of a metal material, but is not limited to a metal material, such as a high temperature resistant plastic. The connection pipe 244 may have a circular, square, triangular or irregular shape. The outer circumference of the connection pipe 244 may be provided with a heating assembly to prevent or solve a problem in that the water flowing through the connection pipe 244 is frozen to block the water inlet pipe 246 before entering the ice making assembly 22.

Inlet pipe 246 may be circular, square, triangular, or shaped, and the material of inlet pipe 246 may be, but is not limited to, plastic. It will be appreciated that inlet tube 246 may be a circular tube of plastic material, other shapes of plastic material, and other materials. Inlet tube 246 is used to provide a passageway for water to flow through.

In order to form a more convenient assembling relationship among the first bracket 242, the connection pipe 244 and the water inlet pipe 246 of the water inlet assembly 24 for the subsequent installation and removal, a first protrusion 2422 is provided at one side surface of the first bracket 242, the connection pipe 244 is fitted over an outer wall of the first protrusion 2422, and in addition, the water inlet pipe 246 is inserted into the first protrusion 2422 and communicates with the connection pipe 244 so that water can flow through the water inlet pipe 246 and the connection pipe 244.

It should be noted that, in the embodiment of the present application, the first through hole 2422a, the connecting pipe 244 and the water inlet pipe 246 are all circular. The outer wall diameter of the first protrusion 2422 and the inner wall diameter of the connection pipe 244 may be set to be equal, and the inner wall diameter of the first protrusion 2422 and the outer wall diameter of the water inlet pipe 246 may be set to be equal. However, in actual manufacturing, due to manufacturing errors, the diameter of the outer wall of the first protrusion 2422 is approximately equal to the diameter of the inner wall of the connection pipe 244, and the diameter of the inner wall of the first protrusion 2422 is approximately equal to the diameter of the outer wall of the water inlet pipe 246. It can be understood that the inner wall diameter of the connection pipe 244 is greater than the inner wall diameter of the first protrusion 2422, and the inner wall diameter of the first protrusion 2422 is greater than the inner wall diameter of the water inlet pipe 246. Further, the radial dimension of the first protrusion 2422 in the first direction X gradually increases (not shown in the drawings). It should be noted that, in the assembling direction of the first protrusion 2422 and the connection pipe 244, the first protrusion 2422 is subjected to the die drawing, as a result of which the outer diameter of the first protrusion 2422 near the first direction X gradually increases, and the outer diameter of the end of the first protrusion 2422 connected to the first bracket 242 does not differ greatly from the outer diameter of the other end of the first protrusion 2422 due to the smaller die drawing slope. By providing the first protrusion 2422 with the pattern drawing structure, the backflow of the water flow in the connection pipe 244 may be reduced.

The connecting pipe 244 is provided with a limiting member 2442, the first protrusion part 2422 is provided with a limiting part 2422c, and the limiting member 2442 and the limiting part 2422c are clamped to limit the connecting pipe 244. For example, the limiting part 2422c includes a limiting groove 2422e, and the limiting part 2442 protrudes toward the limiting groove 2422e and is disposed in the limiting groove 2422 e. It is understood that the stopper groove 2422e is an annular groove provided on the outer wall of the first protrusion 2422. Correspondingly, the limiting member 2442 is an annular protrusion, so that the annular protrusion is engaged with the annular groove to limit the connecting pipe 244. During assembly, the connection tube 244 is slid over the outer wall of the first protrusion 2422 until the annular protrusion snaps into the annular groove. It can be understood that in the case where the diameter of the outer wall of the first protrusion 2422 is approximately equal to the diameter of the inner wall of the connection tube 244, the connection tube 244 can be inserted into the first protrusion 2422 only when at least one of the material of the first protrusion 2422 and the material of the connection tube 244 is an elastic material. For example, the first protrusion 2422 of the embodiment of the present application may be made of an elastic material, and the connection tube 244 may be made of a hard material, so that the connection tube 244 can be slidably sleeved on the outer wall of the first protrusion 2422.

It should be noted that the third portion 2445 is inclined downward to facilitate the water to flow out and also to prevent the water from flowing back to the position where the connection pipe 244 is connected to the first protrusion 2422.

Illustratively, the inlet tube 246 includes an outlet end 2462 and an inlet end, and the inlet end of the inlet tube 246 may be connected to a water source to allow water to flow out through the inlet end of the inlet tube 246 and the outlet end 2462. The water outlet end 2462 is disposed within the second portion 2444 of the connecting tube 244. The water outlet end 2462 of the water inlet tube 246 can be understood to be the end near the connecting tube 244. It should be noted that, the outlet end 2462 of the inlet tube 246 is inserted into the bent portion of the connecting tube 244, so as to reduce the pressure of the water flowing from the small tube to the large tube, and prevent the water from splashing, and at the same time, since the second portion 2444 is also inclined downward while being bent, the backflow of the water is reduced.
