Air conditioner and its connection device between indoor unit and outdoor unit

Abstract

The invention discloses a connecting device for an indoor machine. The connecting device for the indoor machine and the outdoor machine comprises a first connector, a second connector which is in threaded connection with the first connector and an auxiliary screwing piece which is in slide connection with the exterior of the first connector; a rolling column accommodating groove with gradually changed depth is formed in the periphery of the first connector or the internal circumference of the auxiliary screwing piece along the circumferential direction; a rolling column is arranged inside the rolling column accommodating groove in a rolling mode to enable the first connector and the auxiliary screwing piece to be linked along a screwing direction of the first connector and the auxiliary screwing piece. According to the connecting device for the indoor machine and the outdoor machine, the auxiliary screwing piece can only act on the first connector along one direction to achieve connection between the indoor machine and the outdoor machine, the auxiliary screwing piece cannot apply acting force to the first connector during contrarotation, reliable connection between the first connector and the second connector is guaranteed, leakage of heat transferring mediums is avoided due to the auxiliary screwing piece, the wedge groove and the wedge block and installation and maintenance of the indoor machine and the outdoor machine are convenient and installation and maintenance costs of an air conditioner are reduced due to the fact that the connecting device for the indoor machine and the outdoor machine can be arranged indoor. The invention also provides an outdoor machine comprising the connecting device.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a connection device between an indoor unit and an outdoor unit. The present invention also relates to an air conditioner provided with the above connection device. Background technique [0002] The air conditioner absorbs the heat of the indoor air or releases heat to the room through the evaporation or condensation of the refrigerant, so as to achieve the purpose of adjusting the indoor temperature. With the continuous development of science and technology, the performance of air conditioners has received more and more attention. [0003] An air conditioner generally includes two parts, an outdoor unit and an indoor unit. The evaporator of the indoor unit is connected to the condenser of the outdoor unit through a connection device. Outdoor unit connection pipe. According to the difference of the heat exchange medium in the air conditioner, the above connection devic...

AI Technical Summary

Problems solved by technology

[0004] Although the above connection device can solve the problem of heat exchange medium leakage caused by artificial disassembly, setting the connection part between the indoor unit and the outdoor unit outdoors will increase the difficulty of installing and maintaining the air conditioner, making the installation and maintenance of the air conditioner difficult. High maintenance cost

[0005] To sum up, how to reduce the installation and maintenance cost of the air conditioner while solving the leakage of the heat exchange medium caused by the artificial disassembly of the connecting device has become a major technical problem to be solved urgently by those skilled in the art
