Knob structure for fixing side panel at outlet end of indoor machine of commercial air conditioner

Abstract

The invention provides a knob structure for fixing a side panel at the outlet end of an indoor machine of a commercial air conditioner, comprising a knob and knob inserting holes, wherein the knob inserting holes are formed in a front-side connecting part and a rear-side connecting part which are fixedly connected by the knob. The knob is provided with a handle, a turnplate, and a positioning clamp, wherein the handle is integrally formed from top to bottom and is used for applying force rotatably; the turnplate is used for being clamped and embedded in the knob inserting hole of the front-side connecting part; and the positioning clamp is used for supporting a connecting shaft of the rear-side connecting part and is used for clamping the rear-side connecting part so as to prevent the rear-side connecting part from falling off the knob. The knob inserting holes formed on the front-side connecting part and the rear-side connecting part are provided with a through hole and a middle through hole, wherein the through hole has the same shape with the positioning clamp and can pass through the positioning clamp; and the middle through hole is coincident to the through hole and can be embedded in the turnplate. The knob structure has simple structure and can save cost. Tools are not required to disassemble the knob structure, thus solving the problem of inconvenient maintenance or bad installation effect due to narrow maintenance space. As the knob is made of plastic materials, the unusual noise due to the bolt is also overcome.

Description

technical field [0001] The invention relates to an indoor unit of a commercial air conditioner. In particular, it relates to a knob structure for fixing the outlet end side panel of a commercial air conditioner indoor unit. Background technique [0002] An air conditioner is a device that makes its internal refrigerant undergo a refrigeration or heating cycle consisting of a compression process, condensation process, expansion process, and evaporation process. When the air conditioner is in the refrigeration cycle, the refrigerant compressed by the compressor and turned into a high-temperature and high-pressure state can flow to the condenser under the guidance of the four-way valve, and dissipate heat to the outside in the condenser, and then significantly reduce when flowing through the expansion valve. Its temperature and pressure, then the low-temperature, low-pressure refrigerant absorbs heat as it flows through the evaporator, and finally passes through the liquid sto...

AI Technical Summary

Problems solved by technology

Because the side panel 3 is fixed by bolts, the bolts 4 have a certain length, and tools must be used to unscrew the bolts. Since the indoor unit of the commercial air conditioner is embedded in the ceiling of the room, the space for maintenance is narrow, which makes maintenance difficult. Tools are difficult to enter, which makes it impossible to disassemble the body. Even after the body is disassembled for maintenance, there is no guarantee that the indoor unit will cooperate well after maintenance.

In addition, there will also be noise caused by unfastened bolt installation after maintenance.
