Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a sealing structure for the button box of an air conditioner cabinet and an air conditioner. Background Technology

[0002] Existing indoor air conditioning unit cabinets have buttons on the side. Inside the side panel, there's a button box providing a mounting structure for the printed circuit board (PCB) that houses the buttons. To ensure a tight seal within the button box, current solutions involve wrapping a sponge around the cable outlet for a simple seal. However, in certain scenarios, this method is insufficient for a proper seal inside the button box, leading to condensation on the cables. Over time, this can cause short circuits and other failure modes on the PCB. Common solutions involve replacing the gasket with a thicker one or wrapping more layers of sponge to compensate for the insufficient seal, but these methods are still considered unreliable.

[0022] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0023] See Figures 1 to 4 This utility model provides a sealing structure for the button box 1 of an air conditioner cabinet unit, disposed between the button box 1 and the air conditioner cabinet unit, for sealing the gap between the two. The sealing structure comprises:

[0024] A button box 1 is provided with a cable outlet 2 for the cable harness to pass through.

[0025] A sealing body 3 is provided at the outlet 2 and has a wire-binding hole 4 that communicates with the outlet 2. The sealing body 3 is interference-fitted with the inner wall of the outlet 2.

[0026] In this embodiment, the button box 1 is provided with a cable outlet 2 for the cable harness to pass through. The sealing body 3 is installed at the cable outlet 2 and is provided with a cable harness hole 4 connected to the cable outlet 2 to accommodate and guide the cable harness. The sealing body 3 is placed at the cable outlet 2 and is pressed firmly between the button box 1 and the air conditioner cabinet by the button box 1, so that the sealing body 3 and the inner wall of the cable outlet 2 have an interference fit, thereby achieving a good sealing effect. Through the interference fit between the sealing body 3 and the cable outlet 2, the sealing performance can be effectively guaranteed, and it also has a certain degree of installation stability. The overall sealing structure is simple, easy to manufacture and assemble, and can effectively prevent external impurities from entering the air conditioner, improve product safety, and is suitable for various types of air conditioner cabinets.

[0027] The outlet 2 is provided with multiple rounded corner sections 201, and the sealing body 3 is provided with multiple arc sections 301 that are adapted to the rounded corner sections 201. The arc sections 301 are in compression contact with the rounded corner sections 201.

[0028] In this embodiment, as Figures 1-4 As shown, two rounded corner sections 201 are provided on the left side of the outlet 2. The contact surface between the sealing body 3 and the inner wall of the outlet 2 is provided with two arc sections 301 that are adapted to the rounded corner sections 201. During installation, the sealing body 3 is snapped into the outlet 2 from right to left, and then the button box 1 is pressed onto the air conditioner cabinet, so that the arc section 301 of the sealing body 3 and the rounded corner section 201 of the outlet 2 are in compressed contact, which enhances the fit and sealing performance between the sealing body 3 and the outlet 2.

[0029] The cross-section of the sealing body 3 is trapezoidal.

[0030] In this embodiment, the trapezoidal sealing body 3 can generate a greater radial expansion force when inserted into the outlet 2, improving the fit between it and the inner wall of the outlet 2, making it less prone to shaking or falling off after insertion; the conical guiding effect of the trapezoid makes the installation process smoother, and it is also easier to pry it out when removing it.

[0031] The wire harness hole 4 is provided with multiple spiral grooves 5.

[0032] In this embodiment, the spiral grooves 5 are arranged in a circumferential array along the wire harness hole 4. The spiral grooves 5 in the wire harness hole 4 can increase the friction between the wire harness and the wire harness hole 4, making the wire harness more firmly fixed in the hole. When the wire harness in the button box 1 passes through the wire harness hole 4, the spiral grooves 5 can better fit the surface of the wire harness and fill the tiny gaps, thereby providing an additional sealing effect. At the same time, the spiral path helps guide the wire harness to pass through the wire harness hole 4 more smoothly, and can also reduce the wear of the wire harness outer sheath, playing a certain protective role.

[0033] A dividing block 6 is provided between adjacent spiral grooves 5.

[0034] In this embodiment, the wire divider block 6 is a raised structure located between two adjacent spiral grooves 5. Its function is to separate different wire harness channels from each other, playing the roles of isolation, positioning and support. When multiple wire harnesses pass through the wire harness hole 4, it prevents the wire harnesses from getting tangled and improves the neatness of the wiring. When multiple wire harnesses need to pass through at the same time, the wire divider block 6 can effectively manage each line and improve assembly efficiency. The wire divider block 6 can also serve as a support rib to improve the overall rigidity and durability of the wire sealing body 3. In addition, the blocking effect of the wire divider block 6 can reduce the area of ​​the wire harness control and reduce the gaps between the wire harnesses for air, dust and other particles.

[0035] Both the spiral groove 5 and the dividing block 6 are rounded.

[0036] In this embodiment, both the spiral groove 5 and the wire splitting block 6 are rounded, which can effectively reduce the friction between the outer sheath of the wire harness and the spiral groove 5 and the wire splitting block 6, prevent the wire harness from being damaged due to sharp edges, and the smooth rounded surface helps the wire harness to pass through the wire harness hole 4 more smoothly, reducing the resistance to wire threading, and can better fit the surface of the wire harness, fill the tiny gaps, thereby improving the overall sealing performance.

[0037] The button box 1 is provided with a slot 7, which is perpendicular to the cable outlet 2. The sealing body 3 is provided with a plurality of card blocks 302 that are adapted to the slot 7. The card blocks 302 can be detachably inserted into the slot 7.

[0038] In this embodiment, as Figures 1-4 The slot 7 shown is set on the button box 1 and arranged perpendicular to the outlet 2 (the outlet 2 is distributed in the left and right direction, and the slot 7 is set in the up and down direction). The slot 7 is distributed along the outer periphery of the outlet 2. The slot 7 is used to accommodate the two locking blocks 302 on the sealing body 3 to realize the positioning and fixing functions. During installation, the sealing body 3 is inserted into the outlet 2 from right to left, and the two locking blocks 302 are locked in the slot 7. Then the button box 1 and the sealing body 3 are pressed together on the air conditioner cabinet, so that the sealing body 3 can realize the positioning function of both horizontal and vertical, which helps to maintain the tight fit between the sealing body 3 and the outlet 2, thereby improving the overall sealing effect.

[0039] The sealing body 3 is made of elastic material.

[0040] In this embodiment, the sealing body 3 is made of silicone material, which has good elasticity and resilience. After being deformed by pressure during installation, the sealing body 3 can return to its original shape and is used to achieve a seal with the outlet 2 by interference fit.
