[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of them.

[0038] See also Figure 1 , Figure 1 Schematic diagram of the structure of the heat-conducting clip 011 provided in the embodiment of the present application. The present application provides a heat-conducting clip 011, which is applied to a defrosting component, and the defrosting component includes a pipe-type heater and a water receiving tray. The heat-conducting clip 011 includes a first heat-conducting part 111 and a second heat-conducting part 112. Both ends of the first heat-conducting part 111 are provided with a card slot 1111, one of which is clamped with the first section of the heating tube of the heater, and the other card slot 1111 is clamped with the second section of the heating tube of the heating tube. One end of the second heat-conducting part 112 is connected to the first heat-conducting part 111, and the other end is configured to be thermally coupled with the water receiving tray.

[0039] It can be understood that the pipeline heater is a heater that conducts heat through a pipeline. Generally, the pipeline heater includes a pipeline and a heating resistance wire arranged in the pipeline. Among them, the pipeline is a steel pipe.

[0040] In addition, the first heat conducting part 111 and the second heat conducting part 112 both have heat conducting properties. The first heat conducting part 111 conducts heat energy from the heater to the second heat conducting part 112, and the second heat conducting part 112 conducts heat energy from the first heat conducting part 111 to the water receiving pan.

[0041] Exemplarily, the materials of the first heat conducting part 111 and the second heat conducting part 112 include but are not limited to metal, alloy, graphite, thermally conductive ceramics, etc. Among them, the thermally conductive ceramics can be aluminum oxide, boron nitride or silicon carbide, etc.

[0042] In this embodiment, by providing a thermal conductive buckle 011 for the defrost component, on the one hand, the heat energy of the heater can be transferred to the water receiving tray to heat up the water receiving tray, thereby melting the residual ice in the water receiving tray and preventing the residual ice from clogging the drain port of the water receiving tray, thereby allowing the water receiving tray to drain normally; on the other hand, the thermal conductive buckle 011 is connected to the heater through the slot 1111, and there is no need to configure components such as screws and related installation tools, so that the installation method of the thermal conductive buckle 011 is simple and easy to operate, which not only improves the installation efficiency but also facilitates maintenance.

[0043] See also Figure 2 , Figure 2 This is a front view of the heat-conducting buckle 011 provided in an embodiment of the present application. In some embodiments of the present application, the notches of the two slots 1111 are arranged on the first heat-conducting portion 111 opposite to each other.

[0044] For example, when the heat conductive buckle 011 is connected to the heating tube (the heating tube includes the first heating tube and the second heating tube), the line connecting the centers of the two slots 1111 is parallel to the horizontal plane, so that the first section of the heating tube and the second section of the heating tube are subjected to symmetrical forces, thereby improving the stress state of the heating tube. Figure 3 As shown, Figure 3 Schematic diagram of the cooperation between the heat conductive buckle 011 provided in the embodiment of the present application and the pipe of the heater.

[0045] In addition, in order to improve the installation stability of the heat conducting clip 011, the heat conducting clip 011 is abutted between the first section heating tube and the second section heating tube. Specifically, along the arrangement direction of the first section heating tube and the second section heating tube, the minimum spacing between the two clip grooves 1111 is S 1 , the minimum distance between the first section heating tube and the second section heating tube is S 1 , the minimum distance between the first section heating tube and the second section heating tube is S 2 , satisfy: S 1 >S 2 . And S 1 With S 2 The difference between them is δ, which satisfies 0.1mm≤δ≤3mm. δ includes but is not limited to 0.1mm, 0.5mm, 1mm, 2mm, and 3mm.

[0046] In this embodiment, by arranging the notches of the two clamping slots 1111 opposite to each other, the clamping force between the first heat conducting part 111 and the heating tube is symmetrical, thereby improving the stress state of the heat conducting clamp 011 and further enhancing the working stability of the heat conducting clamp 011.

[0047] See also Figure 4 and Figure 5 , Figure 4This is a structural diagram of another thermal conductive buckle 011 provided in an embodiment of the present application. Figure 5 A schematic diagram of another heat-conducting buckle 011 provided in an embodiment of the present application cooperating with a pipe of a heater. In some other embodiments of the present application, the notches of the two slots 1111 are disposed on the first heat-conducting portion 111 with the notches facing each other.

[0048] See also Figure 6 , Figure 6 This is a schematic diagram of the structure of another thermal conductive buckle 011 provided in an embodiment of the present application. In some other embodiments of the present application, the notches of the two card slots 1111 face the same direction.

[0049] See also Figure 3 or Figure 5 In some embodiments of the present application, the groove walls of the two grooves 1111 are respectively in contact with the outer walls of the first section of the heating tube and the second section of the heating tube.

[0050] Exemplarily, when the cross section of the heating tube is circular, the groove wall of the slot 1111 is a cylindrical arc surface, and the diameter of the groove wall of the slot 1111 is consistent with the outer diameter of the heating tube fitted therewith.

[0051] In this embodiment, by fitting the card slot 1111 with the heating tube that cooperates with it, the contact surface between the heat-conducting card buckle 011 and the heating tube can be increased, thereby improving the stability of the heat-conducting card buckle 011 installed on the heater. As a result, the heat-conducting card buckle 011 can be stably in the heat-conducting position, which is conducive to improving the working stability of the heat-conducting card buckle 011.

[0052] See also Figure 7 , Figure 7 The schematic diagram of the structure of the card slot 1111 provided in the embodiment of the present application. In some embodiments of the present application, the slot width of the card slot 1111 is d. In the slot width direction of the card slot 1111, there is a spacing D between the slot walls of the card slot 1111, satisfying: d<Dmax.

[0053] It can be understood that when the groove wall of the card slot 1111 is in contact with the outer wall of the heating tube, the outer diameter of the heating tube is greater than the slot width of the card slot 1111. When the heat-conducting buckle 011 is connected to the heating tube, the slot of one card slot 1111 is firstly opposite to the first section of the heating tube, and then the heat-conducting buckle 011 is pressed hard to make the first section of the heating tube snap into the card slot 1111. Then the first heat-conducting part 111 is bent to increase the distance between the two card slots 1111, and the first section of the heating tube and the second section of the heating tube are squeezed to reduce the distance between the first section of the heating tube and the second section of the heating tube until the slot of the other card slot 1111 is opposite to the second section of the heating tube. Then the heat-conducting buckle 011 is pressed hard until the second section of the heating tube snaps into the other card slot 1111.

[0054] In this embodiment, through the above-mentioned limitation, the slot width of the slot 1111 is smaller than the diameter of the heating tube, so that the heating tube will not fall out of the slot 1111 at will, thereby improving the position stability of the heating clip installed on the heater.

[0055] In some embodiments of the present application, the first heat conducting portion 111 and the second heat conducting portion 112 are integrally formed.

[0056] It can be understood that the first heat conducting part 111 and the second heat conducting part 112 can be formed by bending a metal strip, or can be integrally formed by casting, or can be integrally formed by sintering a ceramic material.

[0057] Exemplarily, the heat-conducting clip 011 is formed by bending a metal strip in one piece. One end of the metal strip is configured to be thermally coupled with the water receiving tray. The other end of the metal strip is bent to form a slot 1111, and the middle of the metal strip is bent to form another slot 1111. In this way, the heat-conducting clip 011 can be thermally coupled with the water receiving tray through an elastic extended edge, so that elastic deformation can be generated on the heat-conducting clip 011, and based on the elastic deformation, the heat-conducting clip 011 can be pressed against the water receiving tray, thereby improving the reliability of heat transfer between the heat-conducting clip 011 and the water receiving tray.

[0058] In this embodiment, the first heat conducting part 111 and the second heat conducting part 112 are integrally formed. On the one hand, the connection surface inside the heat conducting buckle 011 can be reduced, thereby improving the structural stability and reliability of the heat conducting buckle 011; on the other hand, multiple processing, splicing and position adjustment processes can be avoided, thereby simplifying the process flow and further improving manufacturing efficiency.

[0059] In some embodiments of the present application, the first heat conducting portion 111 and the second heat conducting portion 112 are metal parts.

[0060] Exemplarily, the first heat conducting part 111 and the second heat conducting part 112 include, but are not limited to, aluminum, iron, copper, aluminum alloy, copper alloy, etc. Optionally, the first heat conducting part 111 and the second heat conducting part 112 are made of aluminum. Aluminum is ductile, tough and light, and has good thermal conductivity, and can more efficiently transfer the heat energy of the heater to the water receiving pan.

[0061] In this embodiment, by making the first heat conducting part and the second heat conducting part 112 into metal parts, on the one hand, the heat conducting buckle 011 has higher thermal conductivity and durability; on the other hand, the heat conducting buckle 011 has good machinability, which is conducive to controlling the processing cost.

[0062] See also Figure 2 , Figure 4 or Figure 6In some embodiments of the present application, one end of the second heat conducting part 112 is connected to a surface of the first heat conducting part 111 close to a slot 1111. The other end of the second heat conducting part 112 extends toward another slot 1111 and the water receiving tray, and is thermally coupled to the water receiving tray.

[0063] In this embodiment, the above-mentioned configuration enables the second heat-conducting part 112 to be located between the first heat-conducting part 111 and the water receiving tray, so that based on the restrictions of the heating tube and the water receiving tray on both ends of the heat-conducting buckle 011, the heat-conducting buckle 011 can be elastically compressed to elastically abut the heat-conducting buckle 011 against the water receiving tray, thereby making the heat-conducting buckle 011 and the water receiving tray tightly abutted, and finally making the thermal coupling between the heat-conducting buckle 011 and the water receiving tray more stable and reliable.

[0064] See also Figure 8 , Figure 8 The present invention provides a structural schematic diagram of a defrost assembly 001 provided in an embodiment of the present invention. Accordingly, the present invention provides a defrost assembly 001, which includes a pipe-type heater 012, a water receiving tray 013, and the aforementioned heat-conducting clip 011. The pipe-type heater 012 includes a first section of a heating tube and a second section of a heating tube. The water receiving tray 013 is located below the pipe-type heater 012. Among them, one clip slot 1111 is clipped with the first section of the heating tube, and the other clip slot 1111 is clipped with the second section of the heating tube, such as Fig. 9 As shown, Fig. 9 for Figure 8 The enlarged view of the point A in the middle. The end of the second heat conducting part 112 away from the first heat conducting part 111 is thermally coupled to the water receiving tray 013 .

[0065] Exemplarily, the pipe heater 012 includes a bracket 122, a metal tube 121 and a heating resistor. The bracket 122 is used to support the metal tube 121. The heating resistor is arranged in the metal tube 121, and the heating resistor is connected to the power supply circuit. The metal tube 121 can be a steel tube. The heat conductive buckle 011 is clamped with the metal tube 121.

[0066] In addition, the water receiving tray 013 is made of aluminum, which can improve the heat conduction effect of the heat conductive buckle 011 to the water receiving tray 013, thereby improving the heat absorption efficiency of the water receiving tray.

[0067] In order to further improve the problem of residual ice not completely melting in the water receiving pan 013, the bracket 122 is a metal bracket, which is located above the water receiving pan 013. The side of the bracket 122 close to the water receiving pan 013 extends into the water receiving pan 013 and is thermally coupled with the water receiving pan 013. In this way, the heat conduction surface between the pipeline heater 012 and the water receiving pan 013 can be increased, thereby improving the heat conduction efficiency, and then increasing the heat absorption rate of the water receiving pan 013, and finally further improving the problem of residual ice not completely melting in the water receiving pan 013.

[0068] The metal tube 121 includes two long U-shaped pipes arranged in parallel, one end of the two long U-shaped pipes are connected to each other, and the other end extends to the power supply circuit in a direction away from the water receiving tray 013. One slot 1111 is engaged with one long U-shaped pipe, and the other slot 1111 is engaged with the other long U-shaped pipe. In the long U-shaped pipes, the pipe sections engaged with the slots 1111 are of the same height.

[0069] Correspondingly, the present application also provides a refrigerator, which includes the defrost assembly 001 as described above.

[0070] It can be understood that the refrigerator further includes an evaporator 002, and the defrosting component 001 is located directly below the evaporator 002. Fig.10 As shown, Fig.10 Schematic diagram of the positional relationship between the defrost assembly 001 and the evaporator 002 provided in the embodiment of the present application. The defrost assembly 001 is used to heat and melt the frost on the evaporator 002 and the components located around the evaporator 002. The defrost water formed after melting drips into the water receiving tray 013, and the defrost water is discharged to the outside of the refrigerator through the water receiving tray 013 and the drain pipe.

[0071] Exemplarily, the support frame of the evaporator 002 is connected to the bracket 122 of the duct heater 012 as a whole. In this way, the heating efficiency of the duct heater 012 on the evaporator 002 can be improved.

[0072] The basic concepts have been described above. Obviously, for those skilled in the art, the above detailed disclosure is only for example and does not constitute a limitation of the present application. Although not explicitly stated herein, those skilled in the art may make various modifications, improvements and amendments to the present application.
