Referring to fig. 1 to 3, it can be understood that a defrosting assembly 100 according to an embodiment of the present application includes a water tray 10 and a heating component, wherein the heating component is disposed above the water tray 10.

The water receiving tray 10 is configured with a water receiving tank 11 and a drain outlet 12, the water receiving tank 11 is recessed with respect to the top surface of the water receiving tray 10, and the drain outlet 12 is located at a position where the recess depth of the water receiving tank 11 is maximum. It will be appreciated that the depth of the recess of the water receiving tank 11 gradually increases toward the water discharge opening 12 so that water in the water receiving tank 11 flows toward the water discharge opening 12 under the action of gravity, thereby facilitating the water in the water receiving tank 11 to be discharged cleanly.

The heating component comprises a heating element 20 and a mounting element 30, wherein the heating element 20 is arranged above the mounting element 30, and the heating element can be connected to the mounting element in a welding, clamping or fastening way to form an integral assembly with the mounting element. The installation piece 30 and the water receiving disc 10 are positioned through the positioning component 40, so that the heating piece 20 is conveniently connected to the water receiving disc 10 through the installation piece 30.

In the installation process, the heating element 20 can be connected to the mounting element 30 by welding, clamping or fastening, so as to form a combined element with the mounting element 30. Then, the positioning component 40 is matched to position the mounting piece 30 and the water receiving disc 10, so that the mounting between the heating piece 20 and the water receiving disc 10 is facilitated, and the mounting efficiency can be improved.

It can be appreciated that in the defrosting assembly 100 provided in this embodiment of the present application, the heating element 20 is disposed above the mounting element 30, that is, the heating element 20 is connected to the mounting element 30 by welding, fastening or fastening, so as to form an integral assembly with the mounting element 30, and the mounting element 30 and the water receiving tray 10 are positioned by the positioning component 40, so that when the defrosting assembly 100 is mounted or the defrosting assembly 100 is reinstalled after being dismounted, the heating element 20 can be well overlapped with the water receiving tray 10 through the mounting element 30, thereby avoiding assembly errors and further improving assembly efficiency.

With continued reference to fig. 1 and 2, it will be appreciated that the positioning member 40 includes a positioning hole 41 and a positioning protrusion 42, the positioning hole 41 being provided in one of the mounting member 30 and the drip tray 10, and the positioning protrusion 42 being provided in the other of the mounting member 30 and the drip tray 10.

That is, the positioning hole 41 may be provided on the water receiving tray 10, and the positioning protrusion 42 is correspondingly provided on the mount 30. The positioning hole 41 may also be provided on the mounting member 30, and the positioning protrusion 42 is correspondingly provided on the water receiving tray 10. The following embodiments of the present application will be described in detail taking an example that the positioning hole 41 is provided on the mount 30 and the positioning protrusion 42 is correspondingly provided on the drip tray 10.

In some cases of the present application, the mounting member 30 includes a mounting body 31 of a rectangular structure made of sheet metal, which is not only convenient to process, but also has good heat conductivity, and can transfer heat of the heating member 20 to the water pan 10.

The mounting body 31 has a first side and a second side (not shown) disposed opposite to each other, the first side of the mounting body 31 is provided with a first extension 37 extending in a width direction, the positioning hole 41 is provided in the first extension 37, and the shape of the positioning hole 41 may be any shape such as rectangle, square, circle, triangle, etc. The shape of the positioning projection 42 is adapted to the shape of the positioning hole 41 so that the positioning projection 42 can be inserted into the positioning hole 41 to be positioned in cooperation with the positioning hole 41.

With continued reference to fig. 1 to 3, it can be understood that the first side of the mounting body 31 is further provided with a first limiting portion 33 extending upward, that is, the first limiting portion 33 extends along the height direction of the mounting body 31. The edge of the heating element 20 is limited at one side of the first limiting portion 33, and the first limiting portion 33 is used for limiting the degree of freedom of the heating element 20, so as to avoid the movement of the heating element 20.

The first limiting portion 33 may be a rib protruding upward from the surface of the mounting body 31, which can limit not only the degree of freedom of the heating element 20. The ribs can also be bent to be clamped on the heating element 20, so as to fix the heating element 20.

Wherein, the first limiting portion 33 can be integrally formed with the mounting body 31, so that the first limiting portion 33 and the mounting body 31 are convenient to process. Of course, the first limiting portion 33 may be a separate member, which corresponds to the first limiting portion 33 being provided separately from the mounting body 31, and the first limiting portion 33 being connected to the mounting body 31 by welding or fastening.

With continued reference to fig. 1-3, it will be appreciated that the first side of the mounting body 31 also extends downwardly to provide an ice blocking portion 32, and that the ice blocking portion 32 extends into the drain opening 12 and provides a water gap with the sidewall of the drain opening 12.

When the mounting piece 30 and the water pan 10 are positioned by the positioning component 40, the ice blocking part 32 stretches into the water outlet 12, a water gap is arranged between the ice blocking part 32 and the side wall of the water outlet 12, and the ice blocking part 32 and the side wall of the water outlet 12 are matched to play a role in blocking ice. In this way, crushed ice carried in the defrost water can be blocked by the ice blocking portion 32 at the position of the drain port 12, so that crushed ice carried in the defrost water is prevented from entering the drain pipeline to be accumulated in the drain pipeline to be blocked. At the same time, the crushed ice blocked at the drain port 12 may continue to melt under the action of the heating member 20 until the crushed ice is completely melted or melted until it can pass through the water gap.

Wherein the cross-sectional shape of the ice blocking portion 32 is adapted to the cross-sectional shape of the drain opening 12. For example, when the cross-sectional shape of the drain opening 12 is triangular, the cross-sectional shape of the ice blocking portion 32 may be triangular, the cross-sectional area of the ice blocking portion 32 is smaller than the water passing area of the drain opening 12, and after the ice blocking portion 32 extends into the drain opening 12, a gap is formed between the ice blocking portion 32 and the side wall of the drain opening 12, so that the water in the water tray 10 can be smoothly discharged from the drain opening 12.

When the cross-sectional shape of the drain port 12 is triangular, the cross-sectional shape of the ice blocking portion 32 may be an inverted trapezoid, so that the gap between the side wall of the drain port 12 and the ice blocking portion 32 can be increased, so that the water discharge of the water tray 10 is smoother.

Of course, the cross-sectional shape of the ice blocking portion 32 may be semicircular or other shapes. For example, in order to make the water discharge of the drip tray 10 smoother, the ice blocking portion 32 may be a protrusion that may abut against opposite side walls of the drain opening 12. In addition, a groove matching with the protrusion may be provided on the sidewall of the drain port 12.

In some cases of the present application, the ice blocking portion 32 is integrally formed with the mounting body 31, so that the ice blocking portion 32 and the mounting body 31 are convenient to process. Of course, the ice blocking portion 32 may be provided as a separate member, which corresponds to the ice blocking portion 32 being provided separately from the mounting body 31, and the ice blocking portion 32 being connected to the mounting body 31 by welding or fastening.

With continued reference to fig. 1 to 3, it can be appreciated that the second side of the mounting body 31 is provided with a second extension 34 extending in the width direction, and the extending direction of the second extension 34 is opposite to the extending direction of the first extension 37. The second extension 34 abuts against the lower surface of the heating element 20, and is used for supporting the heating element 20, so as to avoid deformation of the heating element 20 due to the bearing gravity or extrusion of the water pan 10.

Equivalently, the second extending portion 34 with a plate-shaped structure is extended outwards along the width direction of the mounting body 31 at the position, close to the two ends, of the mounting body 31, and the second extending portion 34 and the mounting body 31 form a structure with a U-shaped cross section, so that the heating element 20 can be well supported, and the heating element 20 is prevented from being deformed under pressure.

The extending length of the second extending portion 34 may be set according to actual needs, and the present application is not limited specifically, and when the length of the second extending portion 34 is required to be greater, the second extending portion 34 may be correspondingly extended, so that the contact area between the heating element 20 and the second extending portion 34 is increased.

As shown in fig. 1, the mounting portion 36 may be formed by bending a protrusion extending from a side edge of the mounting body 31, that is, the mounting portion 36 and the mounting body 31 are integrally formed, so as to facilitate processing of the mounting portion 36 and the mounting body 31. Of course, the mounting portion 36 may be provided as a separate member, which corresponds to the mounting portion 36 and the mounting body 31 being provided separately, and the mounting portion 36 being connected to the mounting body 31 by welding or fastening.
