Description

Technical Field

[0001] This utility model relates to the field of elevator air conditioning technology, and in particular to an elevator air conditioning filter return air outlet. Background Technology

[0002] Air conditioning filter return air vents are important components in air conditioning systems for achieving air circulation and preliminary purification. Their core function is to draw indoor air into the air conditioning system, intercept impurities in the air through filters, and then return it to the room after cooling, ensuring continuous renewal of indoor air and maintaining the stability of temperature and humidity.

[0003] Most existing air conditioner return air vents have independent filter slots. They filter dust, hair, fibers, large particles and other impurities from the air through built-in filters, reducing pollutants entering the air conditioner. This protects the air conditioner core from dust accumulation affecting heat dissipation or bacterial growth, and indirectly improves indoor air quality. When replacing the filter, there is no need to disassemble the entire return air vent, making the operation more convenient. However, when the return air velocity is too high or the air conditioner vibrates during use, the return air can easily be discharged through the gaps in the filter slot, generating significant noise. At the same time, unfiltered air can pollute the environment. Therefore, a new type of elevator air conditioner return air vent is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an elevator air conditioning filter return air outlet, which aims to improve the problem that the filter slot of the elevator air conditioning return air outlet cannot be sealed, resulting in gas leakage and noise and pollution.

The air conditioner body 1 includes internal components such as a refrigeration compressor, condenser, capillary tube, and evaporator, all of which are existing technologies and not improvements to this application, and will not be described in detail here. A fixed shell 3 is fixedly connected to the outer side of the body 1, protecting the internal structure. An air outlet duct 2 is fixedly connected to the outer side of the body 1, through which the cooled gas is discharged. A return air duct 4 is fixedly connected to the middle of the fixed shell 3, connecting to external return air. The gas enters the unit 1 through the return air duct 4 for filtration. A fixing groove 5 is provided on the outside of the return air duct 4, which facilitates the fixing of the external return air duct with a clamp. A sealing mechanism is installed on the top of the fixed shell 3 to prevent the return air from being discharged through the gap at the top of the fixed shell 3. A filter plate 18 is slidably connected inside the fixed shell 3. The filter plate 18 filters the return air, reducing the large amount of dust and particles entering the unit 1 and affecting the working efficiency of the unit 1. A fixing component is installed inside the fixed shell 3 to facilitate the quick and easy installation of the filter plate 18.

[0012] The sealing mechanism includes a rotating assembly and a snap-fit ​​assembly. The rotating assembly includes a fixed rod 12, which is fixedly connected to the middle of the fixed housing 3.

A groove 19 is provided on the top of the filter plate 18. The filter plate 18 can be quickly removed from the fixed shell 3 for replacement by pinching the groove 19, which greatly improves work efficiency.

[0014] Working principle: After a certain period of use, the filter plate 18 is replaced. First, turn the handle 6 to separate the buckle 7 from the hook 8 and remove the buckle 7. At this time, the cover 9 will quickly rotate and open under the action of the torsion spring 13. Move the slider 15 to drive the locking block 14 to move. Pinch the groove 19 to quickly remove the filter plate 18. Then, insert the new filter plate 18 into the fixing shell 3. The fixing shell 3 first squeezes the locking block 14 to retract. When the filter plate 18 is installed in place, the locking block 14 will rebound under the action of the spring 17 to quickly fix the filter plate 18, which can reduce the impact of air conditioner vibration on the filter plate 18. After replacing the filter plate 18, turn the cover 9 to make the buckle 7 engage with the hook 8. Turn the handle 6 to make the cover 9 and the sealing gasket 10 fit tightly against the top of the fixing shell 3 to seal the fixing shell 3 and prevent the air conditioner return air from being discharged through the gap, generating a lot of noise and polluting the environment.
