Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features.

Any embodiment described in this application as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0030] In order to enable any person skilled in the art to implement and use the present application, the following description is provided. In the following description, details are listed for the purpose of explanation. It should be understood that one of ordinary skill in the art will recognize that the present application can be implemented without using these specific details. In other examples, known structures and processes will not be elaborated in detail to avoid unnecessary details that make the description of the present application obscure.

[0031] The present application embodiment provides a chassis device, such as Figures 1 to 8 As shown, the chassis device provided in the embodiment of the present application includes a first chassis 100 and a second chassis 200, the first chassis 100 is provided with a accommodating cavity 101, the top of the first chassis 100 is provided with an opening connected to the accommodating cavity 101, and the second chassis 200 is covered at the opening on the top of the first chassis 100; an electric heating module 300 for heating the second chassis 200 is provided in the accommodating cavity 101, and the inner surface of the accommodating cavity 101 is covered with a heat insulation layer.

[0032] The chassis device and air conditioner provided in the embodiment of the present application are configured such that the second chassis 200 is covered at the opening at the top of the first chassis 100, and the electric heating module 300 is arranged in the accommodating cavity 101 of the first chassis 100, and the inner surface of the accommodating cavity 101 is covered with a heat insulation layer, so that the heat generated by the electric heating module 300 during heating can be isolated from the outside air, reducing heat dissipation, so that a large amount of heat can directly contact and exchange heat with the second chassis 200, and when rain and snow fall into the second chassis 200, they can melt in time, so that the chassis device can remain in an ice-free state for a long time, the air conditioner can operate normally for a long time, and the user's comfort can be guaranteed.

[0033] Specifically, Figure 2 , Figure 4 and Figure 5 As shown, the first chassis 100 and the second chassis 200 are stacked, and the second chassis 200 is located above the first chassis 100. The first chassis 100 is provided with a receiving cavity 101 with sufficient space to install the electric heating module 300. The electric heating module 300 can be an electric heating tube or an electric heating belt.

[0034] In some embodiments of the present application, Figure 2 , Figure 6 to Figure 8As shown, a groove 102 that is concave outward is provided on one side of the accommodating cavity 101 opposite to the opening (i.e., the bottom surface of the accommodating cavity 101), and the electric heating module 300 is arranged in the groove 102. It is understandable that, since the groove 102 is formed by a part of the accommodating cavity 101 being concave outward, the inner surface of the groove 102 is also covered with a heat insulation layer. By arranging the electric heating module 300 in the above-mentioned groove 102, the electric heating module 300 can be kept at a suitable distance from the second chassis 200, so that the heat is evenly distributed in the accommodating cavity 101, and the electric heating module 300 is prevented from being too close to the bottom of the second chassis 200, resulting in the heat not being evenly distributed in the accommodating cavity 101, thereby resulting in different ice-melting efficiencies at different positions of the second chassis 200, affecting the ice-melting effect of the chassis device as a whole.

[0035] Optionally, the thickness of the heat insulation layer is greater than 0 and less than or equal to 2 mm, for example, it can be 0.5 mm, 0.8 mm, 1 mm, 1.5 mm, 1.8 mm or 2 mm, etc., and can be set according to actual needs.

[0036] In some embodiments of the present application, Figure 6 and Figure 7 As shown, a plurality of support columns 103 are provided in the accommodating cavity 101, and the plurality of support columns 103 are arranged at intervals and support the second chassis 200. By providing the support columns 103, the second chassis 200 can be prevented from collapsing and deforming, thereby improving the structural stability of the second chassis 200. Optionally, the shape of the support columns 103 can be cylindrical, cylindrical, cuboid or other shapes, which can be specifically arranged according to actual needs.

[0037] Optionally, the number of support columns 103 may be two or more, which may be set according to actual needs. Figure 6 and Figure 7 As shown, there are six support columns 103 , which are evenly divided into two groups. The two groups of support columns 103 are arranged at intervals in the width direction of the first chassis 100 , and the three support columns 103 in each group of support columns 103 are arranged at intervals in the length direction of the first chassis 100 .

[0038] In some embodiments of the present application, Figure 2 and Figure 3 As shown, a circle of limiting steps 201 is provided at the bottom edge of the second chassis 200 (i.e., the limiting steps 201 are provided along the circumference of the second chassis 200), and the top surface of the side wall of the first chassis 100 abuts against the step surface of the limiting steps 201. By adopting the above structure, the second chassis 200 can be limitedly supported on the top of the first chassis 100 to prevent the second chassis 200 from shifting in the horizontal direction.

[0039] Optional, such as Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, a first drain hole 104 is provided at the bottom of the first chassis 100, and a second drain hole 202 is provided at the bottom of the second chassis 200; the chassis device further comprises a drain pipe 400, and both ends of the drain pipe 400 are respectively connected to the first drain hole 104 and the second drain hole 202, that is, one end of the drain pipe 400 is connected to the first drain hole 104 and the other end of the drain pipe 400 is connected to the second drain hole 202. By providing the first drain hole 104, the second drain hole 202 and the drain pipe 400, water on the second chassis 200 can be discharged in time to prevent water from accumulating in the second chassis 200, and water on the second chassis 200 will not flow into the accommodating cavity 101 to damage the electric heating module 300.

[0040] Optional, such as Figure 1 As shown, the second chassis 200 is provided with a wire outlet hole 203 which is in communication with the accommodating cavity 101 and is used for the wire outlet of the electric heating module 300, and the wires of the electric heating module 300 are passed through the wire outlet hole 203. By providing the wire outlet hole 203, it is convenient to connect the electric heating module 300 with the power supply module and control module of the air conditioner.

[0041] Optional, such as Figure 1 and Figure 5 As shown, the second chassis 200 includes a first installation area 204 and a second installation area 205 for installing the compressor, and the first chassis 100 is located below the first installation area 204. It can be understood that the various positions of the chassis device have different load-bearing requirements and different functions. The position where the compressor is installed (i.e., the second installation area 205) is only a single-layer chassis structure due to the weight of the compressor and no need to melt ice, that is, the first chassis 100 is not set below the second installation area 205; while the position where the condenser module, motor bracket, middle partition and other lightweight components are installed (i.e., the first installation area 204) is in contact with the external environment, and rain and snow can enter the position where these components are installed (i.e., the first installation area 204), so the first chassis 100 is set below the first installation area 204, so that the electric heating module 300 set in the first chassis 100 can melt the rain and snow falling into the first installation area 204 to prevent the first installation area 204 from freezing.

[0042] In some embodiments of the present application, Figure 1 to Figure 6 As shown, the chassis device further includes a support base 500, and the support base 500 is supported on the bottom of the first chassis 100, that is, the first chassis 100 and the second chassis 200 are supported by the support base 500. Optionally, the support base 500 is provided with a mounting hole 501 for connecting with an external device, so that the entire chassis device can be mounted on the external device through the mounting hole 501 on the support base 500.

[0043] Optionally, there are multiple support bases 500, and the multiple support bases 500 are arranged at intervals along the extension direction of the first chassis 100. For example, Figure 1 and Figure 5 As shown, there are two support bases 500 , and the two support bases 500 are arranged at intervals along the extension direction of the first chassis 100 (ie, the length direction of the first chassis 100 in the figure).

[0044] The embodiment of the present application also provides an air conditioner, which includes a chassis device, and the specific structure of the chassis device refers to the above embodiment. Since the air conditioner adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0045] Specifically, in a low-temperature rain and snow environment, the air conditioner turns on the electric heating module 300 as needed. The electric heating module 300 generates a large amount of heat when working. Since the inner surface of the accommodating cavity 101 of the first chassis 100 is covered with an insulation layer, the heat generated by the electric heating module 300 can only be heat exchanged with the second chassis 200, and since the heat has no other direction of heat exchange, the heat exchange efficiency is basically 100%. At the same time, the gaseous heat can contact the entire second chassis 200, and the heat exchange area can also be maintained at 100%, which is far higher than the heat exchange efficiency and heat exchange area of ​​placing electric heating tubes or electric heating belts on the chassis surface in the prior art. Therefore, when rain and snow fall into the second chassis 200, they can melt in time, so that the chassis device can remain in an ice-free state for a long time, and the air conditioner can operate normally for a long time, ensuring the user's comfort.

[0046] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0047] The chassis device and air conditioner provided in the embodiments of the present application are introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea; at the same time, for technical personnel in this field, according to the ideas of the present application, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as a limitation on the present application.
