Description

Technical Field

[0001] This utility model relates to the field of air conditioner controllers, and in particular to a waterproof sealing structure for air conditioner controllers. Background Technology

[0002] Air conditioning controllers have control and regulation functions, communication functions, and safety protection effects. They are responsible for receiving user settings and sensor signals to regulate environmental parameters such as temperature, humidity, and wind speed. Therefore, they are an indispensable and important component in air conditioning operation control.

[0003] Chinese Patent Application No. CN201620690335.5 provides an air conditioner controller. This design includes a dustproof component on the button, which effectively prevents dust from entering the housing, thus improving safety. When the fixing part and dustproof part, made of transparent material, are located above the button, normal operation can be performed without affecting the indicator on the button. Furthermore, the dustproof component prevents the indicator on the button from being worn when operating through it, ensuring normal operation.

[0004] Existing air conditioner controllers have certain drawbacks in use. First, the installation structure of air conditioner controllers is relatively simple in terms of protection during assembly. This means that the air conditioner controller cannot prevent water, dust, or oil from entering after long-term use, which affects the service life of the air conditioner controller. Therefore, we propose a waterproof and sealing structure for air conditioner controllers. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a waterproof sealing structure for an air conditioning controller. By setting a waterproof ring and a sealing ring, the waterproof ring is installed inside the sealing groove of the upper housing during assembly. When the upper housing and the bottom housing are assembled, the waterproof ring, made of silicone rubber, can form a waterproof structure at the joint gap. According to the installation and the size of the surrounding gaps, the waterproof ring can be slightly adjusted in position under the action of the adjusting rod and the reset ring. Multiple adjustable sealing rings are set on the outside of the waterproof ring, which can further improve the sealing structure on the basis of the waterproof ring. This structure can adapt to different housing tolerances and installation errors, improve sealing consistency, and enable the controller to work for a long time in humid, dusty or high temperature difference environments. The sealing structure can significantly improve the anti-aging, anti-corrosion and anti-impact capabilities, thereby extending the life of the controller and the housing.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0017] Furthermore, a mounting component is installed below the inner end of the housing, and gaskets are movably connected to both sides of the mounting component.

[0018] The thermal conductivity of the housing can be improved by installing gaskets.

[0019] Furthermore, the outer end of the middle shell is movably connected to the bottom shell, the upper end of the bottom shell is fixedly connected to symmetrically distributed snap-fit ​​posts, and the inner end of the bottom shell is fixedly connected to snap-fit ​​posts.

[0020] By installing snap-fit ​​posts and locking posts, the connection and assembly between the bottom shell and external components can be made more convenient and stable.

[0021] Furthermore, a heat dissipation groove is provided at the inner end of the bottom shell.

[0022] By incorporating heat dissipation grooves, the bottom shell can be equipped with a heat dissipation structure, thereby improving its practicality.

[0023] In summary, this utility model has the following beneficial effects:

[0024] 1. By setting waterproof rings and sealing rings, the controller has a waterproof ring installed inside the sealing groove of the upper housing during assembly. When the upper housing and the bottom housing are assembled, the waterproof ring, made of silicone rubber, can form a waterproof structure at the joint gap. According to the installation and the size of the surrounding gaps, the waterproof ring can be slightly adjusted in position under the force of the adjusting rod and the reset ring.

[0045] By installing multiple snap-fit ​​posts 301 and 302, the bottom shell 3 can have multiple snap-fit ​​assembly structures, making the connection and assembly between the bottom shell 3 and external components more convenient and stable. The heat dissipation groove 303 can give the bottom shell 3 a heat dissipation structure, improving the practicality of the bottom shell 3.

[0046] Specific implementation process: When assembling the controller structure, multiple snap-fit ​​posts 301 and 302 allow the bottom shell 3 to have multiple snap-fit ​​assembly structures. Multiple snap-fit ​​grooves 201 can be assembled with snap-fit ​​posts 302 when the middle shell 2 and the bottom shell 3 are connected, making the connection and installation between the middle shell 2 and the bottom shell 3 more convenient. Two sets of symmetrically distributed assembly posts 104 can be snapped with snap-fit ​​posts 301, thereby making the assembly connection between the upper shell 1 and the bottom shell 3 more stable.

[0047] After assembly, a waterproof ring 105 is installed inside the sealing groove 103 of the upper housing 1. When the upper housing 1 and the bottom housing 3 are assembled, the waterproof ring 105, made of silicone rubber, can form a waterproof structure at the joint gap. Depending on the installation and the size of the surrounding gap, the waterproof ring 105 can be slightly adjusted in position under the force of the adjusting rod 107 and the reset ring 109. Multiple adjustable sealing rings 110 are set on the outside of the waterproof ring 105, which can further improve the sealing structure based on the waterproof ring 105. This structure can adapt to different housing tolerances and installation errors, improve sealing consistency, and enable the controller to work for a long time in humid, dusty or high temperature difference environments. The sealing structure can significantly improve the anti-aging, anti-corrosion and anti-impact capabilities, and improve the functionality of the controller.
