[0033] The present utility model provides a sealing plug 100.

[0034] Please refer to Figures 1 to 3, in an embodiment of the present utility model, the sealing plug 100 is used for an air conditioner chassis 200. The air conditioner chassis 200 is provided with a drain hole. The sealing plug 100 includes a plug body 110 and a connecting portion 120. One end of the connecting portion 120 is connected to the plug body 110, and the other end is connected to the air conditioner chassis 200. The plug body 110 is used to block the drain hole.

[0035] The technical solution of the present utility model is to set the connecting portion 120 on the sealing plug 100, so that the sealing portion is connected to the air conditioner chassis 200. In this way, when the plug body 110 is removed from the drain hole and the air conditioner chassis 200 drains water, since the connecting portion 120 connects the plug body 110 to the air conditioner chassis 200, the loss of the sealing plug 110 is avoided. When drainage is not required, the plug body 110 can be reused to block the drain opening.

[0036] Secondly, one end of the connecting portion 120 is connected to the plug body 110, and the other end is connected to the air conditioner chassis 200. It can be understood that the connection position between the air conditioner chassis 200 and the connecting portion 120 and the connection position between the connecting portion 120 and the plug body 110 are far away from each other. In this way, there is enough length space for the connecting portion 120 to allow the plug body 110 to avoid and be removed from the drain hole, so that it is not necessary to first disassemble the plug body 110 and then connect the connecting portion 120 to the air conditioner chassis 200. Therefore, the fixing steps of the connecting portion 120 can be saved; since the connecting portion 120 of this solution has enough length avoidance space, the plug body 110 can be directly removed from the drain hole, and the plug body 110 can remain connected to the air conditioner chassis 200, which can save the removal efficiency of the sealing plug 100.

[0037] In other embodiments, when the connection position between the air conditioner chassis 200 and the connecting portion 120 and the connection position between the connecting portion 120 and the plug body 110 are close, that is, when the plug body 110 cannot be avoided and loosened, a clamping portion can also be provided on the air conditioner chassis 200, and a clamping hole can be provided on the connecting portion 120. After the plug body 110 is loosened from the drain hole, the plug body 110 is installed on the air conditioner chassis 200 by using the clamping hole, which can also avoid the loss of the sealing plug.

[0038] Optionally, the connecting portion 120 and the plug body 110 are integrally formed. First of all, the integral forming process directly forms the product through a mold, avoiding problems such as possible errors and deformations in the traditional processing process, thereby greatly improving the accuracy of the sealing plug 100, and reducing the risk that the sealing performance between the sealing plug 100 and the drain hole is poor or the sealing plug cannot be inserted into the drain hole due to accuracy. Secondly, the integral forming process has the characteristics of high automation and can realize automatic operations from raw material mixing, forming to post-treatment and other processes. The integral forming manufacturing method greatly improves the production efficiency and shortens the production cycle of the sealing plug 100.

[0039] Reference Figure 2 and Figure 4 , optionally, the other end of the connecting portion 120 is detachably connected to the air conditioner chassis 200. It can be understood that the detachable connection method facilitates the disassembly and replacement of the sealing plug 100. For example, but not limited to, when the sealing plug 100 loses its elastic sealing ability, the sealing plug 100 can be replaced in a detachable manner, which can save the maintenance and replacement costs. Of course, the present invention is not limited thereto. In some other embodiments, the other end of the connecting portion 120 can also be fixedly connected to the air conditioner chassis 200, such as, but not limited to, bonding.

[0040] Furthermore, a connecting hole 121 is provided at the other end of the connecting portion 120, and the connecting hole 121 is snap-connected to the air conditioner chassis 200. First of all, the snap-connection method can achieve the effect of quick installation. The snap-connection method is simple and fast to operate, eliminating the cumbersome preparation work and waiting time in the traditional connection method, and significantly improving the connection efficiency between the sealing plug 100 and the air conditioner chassis 200. Secondly, snap-connection does not require complex tools. Compared with welding or threaded connection, snap-connection usually does not require complex installation tools, reducing the requirements for the skills of installers and making the installation process more convenient. Of course, the present invention is not limited thereto. In some other embodiments, the connecting portion 120 can also be screwed to the chassis assembly 10.

[0041] In this embodiment, the air conditioner chassis 200 is provided with a fixed clamp, the fixed clamp passes through the connecting hole 121, and the connecting portion 120 is clamped between the fixed clamp and the side wall of the air conditioner chassis 200.

[0042] Reference Figures 3 to 5 , optionally, a plurality of sealing convex rings 130 are spaced apart on the outer peripheral surface of the plug body 110, and independent sealing spaces are formed between the plurality of sealing convex rings 130 to strengthen the sealing performance of the sealing plug 100 and prevent water leakage. That is, even if the user does not fully insert the sealing plug 100 into the drain hole, the independent sealing spaces formed between the plurality of sealing convex rings 130 can also achieve the sealing of the sealing plug 100.

[0043] In one embodiment, in the direction away from the connecting portion 120, the outer diameter of the sealing convex ring 130 is arranged to decrease; it can be understood that the outer diameter of the sealing convex ring 130 is arranged to decrease, that is to say, the overall outer diameter of the sealing plug 100 is arranged to decrease, which helps to form a more uniform pressure distribution between the sealing plug 100 and the sealing surface, thereby improving the sealing effect. This design can reduce the problem of sealing failure caused by uneven pressure.

[0044] Secondly, the outer diameter of the sealing convex ring 130 is set to decrease. During the process of inserting the sealing plug 100 into the drain hole, the design with a gradually decreasing outer diameter can reduce the resistance during insertion and lower the required insertion force. This helps to protect the sealing plug 100 and the sealing surface from damage caused by excessive insertion force.

[0045] Moreover, due to the reduction of friction and wear, the sealing plug 100 with a gradually decreasing outer diameter generally has a longer service life. This can reduce the frequency and cost of replacing the sealing plug 100.

[0046] Furthermore, the sealing plug 100 with a gradually decreasing outer diameter can be more easily installed into a compact space. This design helps to save space and improve the compactness of the overall design. Since the design with a gradually decreasing outer diameter simplifies the installation process, the installation efficiency can be improved. This helps to reduce the installation time and cost.

[0047] Furthermore, in this embodiment, in the direction away from the connecting portion 120, the thickness of the sealing convex ring 130 and the diameter of the sealing plug 100 are set to decrease; this is beneficial to form a more uniform pressure distribution, thereby improving the sealing effect.

[0048] In the second embodiment, in the direction away from the connecting portion 120, the thickness of the sealing convex ring 130 is set to decrease; this is beneficial to form a more uniform pressure distribution, thereby improving the sealing effect.

[0049] In the third embodiment, in the direction away from the connecting portion 120, the diameter of the plug body 110 is set to decrease; this is beneficial to form a more uniform pressure distribution, thereby improving the sealing effect.

[0050] Furthermore, the sealing convex ring 130 includes a first section and a second section connected to each other. One end of the first section away from the second section is connected to the plug body 110, and the side surface of the second section facing the connecting portion 120 and / or the side surface facing away from the connecting portion 120 is provided with a guiding inclined surface.

[0051] Among them, the side surface of the second section facing the connecting portion 120 is provided with a guiding inclined surface, that is, the side surface of the second section facing the connecting portion 120 gradually inclines towards the direction close to the connecting portion 120 in the direction close to the plug body 110. This can guide the sealing plug 100 to loosen from the drain opening. The side surface of the second section facing away from the connecting portion 120 is provided with a guiding inclined surface, that is, the side surface of the second section facing away from the connecting portion 120 gradually inclines towards the direction away from the connecting portion 120 in the direction close to the plug body 110. This can guide the sealing plug 100 into the drain opening, making the installation of the sealing plug 100 more labor-saving.

[0052] Further, in this embodiment, the cross-section of the second section is trapezoidal, which can make the sealing convex ring 130 have a guiding effect while improving the sealing effect. Of course, this embodiment is not limited to this. In other embodiments, the cross-section of the second section can also be triangular or semi-circular.

[0053] Referring Figure 6 , optionally, a deformation groove 111 is provided inside the plug body 110 to facilitate the deformation of the sealing plug 100 to generate a sealing effect

[0054] Optionally, the cross-sectional area of the deformation groove 111 gradually decreases in the direction away from the connecting portion 120. This can adapt to the change of the outer diameter of the plug body 110, make the wall thickness of the sealing plug 100 uniform, and thus improve the sealing performance of the plug body 110.

[0055] The present utility model also proposes a chassis assembly 10, which includes an air-conditioning chassis 200 and a sealing plug 100. The specific structure of the sealing plug 100 refers to the above embodiment. Since this chassis assembly 10 adopts all the technical solutions of the above all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one. Among them, the air-conditioning chassis 200 is provided with a drain hole, and the sealing plug 100 plugs the drain hole.

[0056] The present utility model also proposes an air conditioner, which includes a chassis assembly 10. The specific structure of the chassis assembly 10 refers to the above embodiment. Since this air conditioner adopts all the technical solutions of the above all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0057] Optionally, the air conditioner includes an indoor unit and an outdoor unit, and the chassis assembly 10 is arranged in the indoor unit; the indoor unit and the outdoor unit are connected by a refrigerant hose assembly, and the refrigerant hose assembly is pre-filled with refrigerant; it can be understood that this air conditioner is a split-type air conditioner that is convenient for users to install personally. It uses a refrigerant hose assembly to connect the indoor-side heat exchanger of the air-conditioning indoor unit and the outdoor-side heat exchanger of the air-conditioning outdoor unit, and injects refrigerant into the refrigerant circuit before the equipment leaves the factory. In this way, when the user installs the equipment by himself, he only needs to fix the air-conditioning indoor unit and the air-conditioning outdoor unit respectively, without the need to assemble the refrigerant pipe and fill the refrigerant, thereby reducing the installation difficulty and realizing personal installation by the user. However, this design is not limited to this. In other embodiments, the air conditioner of the present utility model can also be an ordinary split-type air conditioner.

[0058] Among them, the refrigerant hose assembly can be a flexible refrigerant pipe and a sleeve sleeving the flexible refrigerant pipe, or can include any two of a refrigerant pipe, a drain pipe, and an energized wire, and a sleeve sleeving the two at the same time, or is an assembly including a refrigerant pipe, a drain pipe, an energized wire, and a sleeve sleeving the three at the same time, so as to facilitate connection.

[0059] Furthermore, the compressor of the air conditioner is arranged in the indoor unit, which can reduce the weight of the outdoor unit and thus facilitate the installation of the outdoor unit.

[0060] Optionally, a noise reduction structure is provided corresponding to the compressor of the air conditioner to reduce the noise of the compressor installed in the indoor unit.
