[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0036] In the related art, most central air conditioners use a reverse refrigeration defrosting method when defrosting the water pan, but this method will cause irreversible damage to the compressor, shorten the service life of the compressor, and has low reliability. The conventional electric heating method has low heat exchange efficiency and poor economic effect, and is easily corroded by heated water, which in turn affects the entire air conditioner. Therefore, it is necessary to propose a heating device to address the problems of low reliability and poor economic effect of existing air conditioner defrosting devices.

[0037] Combine the following Figures 1 to 6 , describing an embodiment of the present invention.

[0038] According to an embodiment of the present invention, on the one hand, a heating device is provided, comprising a heating component 1 and a heat-conducting component 2, wherein the heating component 1 is suitable for being connected to an external power source; the heat-conducting component 2 comprises a mounting plate 21, the mounting plate 21 having a mounting position for assembling the heating component 1, and the mounting plate 21 having at least one heat-conducting groove 22 connected to the mounting position.

[0039] When applying the heating device of this embodiment, the heating component 1 is assembled on the mounting position of the mounting plate 21, and a mounting groove 23 is opened on the mounting plate 21. The mounting groove 23 is set to pass through the mounting position so that the heat released by the heating component 1 itself can spread to the entire mounting plate 21 through the mounting groove 23, making the heat conduction process more uniform and improving the heat conduction efficiency, thereby reducing the energy consumption of the heating device and effectively solving the problem of low reliability and poor economic effect of the existing air-conditioning defrosting device.

[0040] It should be noted that the heating component 1 is a device that can be connected to an external power source and can generate heat by being energized, and can be but is not limited to an electric heating wire.

[0041] In addition, the mounting plate 21 is a plate-shaped structure having at least one plane for heat conduction, and the heating element 1 is mounted on the other side of the mounting plate 21 facing away from the plane.

[0042] Furthermore, the mounting position is a position on the mounting plate 21 for mounting the heating component 1, and a mounting structure for assembling the heating component 1 is provided on the mounting position, which can be specifically configured according to the structure of the heating component 1 and will not be described in detail.

[0043] In addition, the heat conducting groove 22 is arranged on the mounting plate 21 and is connected to the mounting position, that is, the heat conducting groove 22 can be connected to the heating component 1 on the mounting position. When the heating component 1 is working, the heat can flow along the heat conducting groove 22 to improve the heat exchange efficiency of the mounting plate 21.

[0044] It can be understood that the heat-conducting grooves 22 are evenly distributed on the mounting plate 21 to ensure even distribution of heat. There can be one or more heat-conducting grooves 22. When only one heat-conducting groove 22 is provided on the mounting plate 21, the heat-conducting groove 22 extends on the mounting plate 21 and is evenly distributed; when multiple heat-conducting grooves 22 are provided on the mounting plate 21, the multiple heat-conducting grooves 22 are evenly distributed on the mounting plate 21.

[0045] In one embodiment, the mounting plate 21 is provided with a mounting groove 23 at the mounting position, and the mounting groove 23 has a first cavity, the heating component 1 is located in the first cavity and is fixed in cooperation with the mounting groove 23, and the heat conducting groove 22 intersects with the mounting groove 23. The first cavity is provided in the mounting groove 23 to accommodate the heating component 1, so that the heat conducting groove 22 can be directly connected with the mounting groove 23, thereby improving the heat exchange efficiency of the heat conducting groove 22, and the arrangement of the mounting groove 23 to accommodate the heating component 1 can protect the stability of the heating component 1 itself, reduce bumps, and prevent debris from entering the first cavity.

[0046] It should be noted that the mounting groove 23 is provided on the mounting plate 21 and is used to assemble the heating component 1 , and at least part of the first cavity includes the space inside the mounting groove 23 , that is, the heating component 1 is at least partly installed in the mounting groove 23 .

[0047] Among them, the mounting groove 23 is used to accommodate the heating component 1, and the mounting groove 23 is extended on the mounting plate 21, that is, the heating component 1 can at least partially extend on the mounting plate 21 synchronously with the mounting groove 23. When the mounting grooves 23 can be evenly distributed on the mounting plate 21, the heating component 1 can at least partially be evenly arranged on the mounting plate 21, thereby improving the heat exchange efficiency.

[0048] Furthermore, one side of the mounting plate 21 used for heat conduction and heat exchange is a plane, and the mounting grooves 23 are evenly distributed on the projection of the plane, so that the heating components 1 can be evenly distributed.

[0049] Furthermore, both side surfaces of the mounting plate 21 are flat, and the heating assembly 1 is assembled in the mounting groove 23 to ensure that the side surfaces of the mounting plate 21 are level.

[0050] For ease of understanding, the heat conducting groove 22 and the mounting groove 23 are arranged to intersect each other, and the mounting groove 23 is equipped with a heating component 1 at the intersection position so that the heating component 1 can communicate with the heat conducting groove 22 to facilitate heat transfer.

[0051] In one embodiment, the heating assembly 1 includes transverse sections 11 and bending sections 12 that are alternately arranged, and the plurality of transverse sections 11 are arranged at intervals along the first direction A, and the bending sections 12 are connected between adjacent transverse sections 11. The transverse sections 11 and the bending sections 12 are used to evenly distribute the heating assembly 1 on the mounting plate 21, thereby improving the heating efficiency and avoiding uneven heat dissipation.

[0052] It should be noted that the heating component 1 is evenly distributed on the mounting plate 21 by setting the transverse section 11 and the bending section 12, and the mounting groove 23 should have an extension direction that matches the heating component 1 so that the transverse section 11 and the bending section 12 of the heating component 1 can both be assembled in the mounting groove 23.

[0053] The transverse sections 11 and the bending sections 12 are alternately arranged and connected end to end in sequence, so that the heating component 1 is arranged in a strip shape on the mounting plate 21; at the same time, the mounting groove 23 is arranged corresponding to the heating component 1 to assemble the heating component 1.

[0054] In addition, the transverse sections 11 are evenly spaced apart on the mounting plate 21 along the first direction A, so that the heating components 1 are evenly distributed on the mounting plate 21 .

[0055] In one embodiment, the mounting groove 23 is provided with an opening 231 on one side of the mounting plate 21, and the heating component 1 at least partially extends out of the opening 231 to connect to an external power source. In this way, by utilizing the opening 231 of the mounting groove 23, the heating component 1 can be directly extended from the opening 231 to connect to an external power source, thereby improving the sealing of the heating component 1 inside the first cavity and ensuring the stability of the heating device. Moreover, the method of directly extending from the opening 231 can avoid unevenness on the mounting plate 21 caused by the setting of the heating component 1, further improving the flatness of the mounting plate 21, thereby increasing the contact area of ​​the mounting plate 21 and ensuring the heat exchange efficiency.

[0056] It should be noted that the heating component 1 extends out of the mounting plate 21 through the opening 231 and is connected to an external power source. The size of the opening 231 is set corresponding to the heating component 1 so that the heating component 1 can pass smoothly through the opening 231 to avoid the formation of a bulge on the surface of the mounting plate 21.

[0057] In one embodiment, the mounting plate 21 is provided with a sealing portion at the opening 231, the sealing portion abuts against the side wall of the opening 231, and the heating component 1 is passed through the sealing portion. The heating component 1 extends from the opening 231, and the sealing portion is provided to ensure the sealing of the heating component 1, so as to prevent debris from entering the first cavity from the opening 231 and affecting the heating component 1.

[0058] It should be noted that the sealing portion is arranged at the opening 231 so that the heating component 1 can be passed through while maintaining the sealing inside and outside of the opening 231 to prevent debris and dust from entering the installation groove 23 through the opening 231 by mistake, thereby maintaining the stability of the heating component 1.

[0059] In addition, there are at least two openings 231 , so that two ends of the heating component 1 pass through the openings 231 respectively and are connected to an external power source.

[0060] Furthermore, the openings 231 are all located on the same side of the mounting plate 21 to reduce the wiring of the heating component 1 after it extends out of the opening 231 , thereby making the internal structure of the device simple and clear.

[0061] Furthermore, there may be various ways of connecting the sealing portion and the opening 231, such as but not limited to interference fit, threaded connection, etc.

[0062] In one embodiment, the heat-conducting component 2 includes two mounting plates 21 arranged opposite to each other, the mounting grooves 23 on the mounting plates 21 enclose a first cavity, the mounting position is located in the first cavity, and the heating component 1 is assembled in the first cavity. The mounting grooves 23 on the two mounting plates 21 are used to enclose a through hole with an opening 231, the first cavity is located inside the through hole, and the heating component 1 is arranged in the through hole, which ensures the stability of the first cavity and further improves the reliability of the heating component 1.

[0063] It should be noted that, while the two mounting plates 21 are arranged relative to each other, the mounting grooves 23 on the mounting plates 21 are also correspondingly opened, so that the two mounting grooves 23 are butted against each other and enclosed to form a first cavity for assembling the heating component 1 .

[0064] Furthermore, the two mounting plates 21 surround the first cavity to form a through hole, and the heating component 1 is installed in the through hole and extends out from the opening 231 to be connected to an external power source.

[0065] It is easy to understand that the two mounting plates 21 are both provided with heat conducting grooves 22 , and the heat conducting grooves 22 are respectively connected to the mounting grooves 23 for conducting heat.

[0066] In one embodiment, the heat conducting grooves 22 on the two mounting plates 21 are arranged opposite to each other and enclose a second cavity, which is connected to the first cavity and extends away from the first cavity. By setting the second cavity to be connected to the second cavity, when the heating component 1 in the first cavity is working, the second cavity is used to conduct the heat dissipated in the first cavity and further extend away from the first cavity, thereby improving the uniformity of heat generation on the mounting plate 21 and improving the heat exchange efficiency.

[0067] It should be noted that the heat conducting grooves 22 on the two mounting plates 21 are butted together to form a second cavity. The second cavity is also strip-shaped and is arranged crosswise with the first cavity for easy communication.

[0068] The second cavity extends in a direction away from the first cavity, so that the heat in the first cavity can be conducted along the second cavity to a position on the mounting plate 21 that is farther from the first cavity, which is beneficial to uniform heat conduction.

[0069] In one embodiment, a connecting member 3 is further included, which is fixed to the side of the mounting plate 21 facing away from the mounting position and is used to be detachably connected to the water collection tray. The connecting member 3 can be directly connected to the water collection tray, thereby improving the convenience of the heating device.

[0070] It should be noted that the connector 3 is a component provided on the mounting plate 21 and used to connect with the water collection tray. It should enable the mounting plate 21 to contact with the water collection tray over a large area to facilitate heat conduction.

[0071] Optionally, there are various ways to connect the connector 3 to the water collection tray, including but not limited to gluing, snapping, etc.

[0072] In one embodiment, a heat insulating portion 4 is further included, and the heat insulating portion 4 is located on the side of the heating device away from the water collection tray. In this way, the heat insulating portion 4 is arranged on the side of the heating device facing away from the water collection tray to reduce the heat loss on the side of the heating device facing away from the water collection tray, ensure that the heat of the heating device is concentrated on one side of the water collection tray for heat exchange, and improve the heat exchange efficiency.

[0073] It should be noted that the heat insulation part 4 is a device that can reduce the heat dissipation of the heating device, and is arranged on the side of the heating device facing away from the water accumulation tray. It can be but is not limited to aluminum foil, polyurethane, thermal insulation cotton, etc.
