Floor-type split air conditioner

Abstract

The invention provides a floor-type split air conditioner. The floor-type split air conditioner comprises an indoor machine provided with an indoor heat exchanger and a compressor, an outdoor machine provided with an outdoor heat exchanger, an outdoor fan and an outdoor sensor, and a main control board which is used for controlling the compressor, the outdoor fan and the outdoor sensor to work and arranged in the indoor machine, wherein a throttling component is arranged in the indoor machine or the outdoor machine; the indoor heat exchanger, the throttling component, the outdoor heat exchanger and the compressor sequentially communicate circularly, so that a refrigerant loop is formed; the outdoor fan is connected to a fan wire leading port of the main control board; the outdoor sensor is connected to a temperature sampling port of the main control board; a first absorption component is arranged at the fan wire leading port, and a second absorption component is arranged at the temperature sampling port, so that the floor-type split air conditioner is protected. Through the technical scheme adopted by the floor-type split air conditioner disclosed by the invention, dangers caused by overcurrent or overvoltage in electronic control can be effectively avoided, the service life of the floor-type split air conditioner is prolonged, and the applicability and the safety of the floor-type split air conditioner are improved; besides, the production cost of the floor-type split air conditioner is reduced, and the production efficiency of the floor-type split air conditioner is improved.

Description

Technical field [0001] The invention relates to the technical field of household appliances, in particular to a split floor-standing air conditioner. Background technique [0002] At present, the existing split floor-standing air conditioners, due to the indoor unit space, noise and other factors, place the compressor in the outdoor unit of the split floor-standing air conditioner, and set the corresponding main control board in the outdoor unit , Separated from the outdoor fan by the central partition, the indoor unit and the outdoor unit communicate through the current loop communication circuit, and because the communication line is attached to the AC power line, it is easy to cause high-voltage damage, line interference and slow transmission speed; moreover, the circuit The structure is more complicated, such as: indoor and outdoor units need to be equipped with switching power supply circuits to provide working voltage for main control boards, relays, etc.; indoor and outdoo...

AI Technical Summary

Problems solved by technology

[0002] At present, due to factors such as the indoor unit space and noise of the existing split floor air conditioners, the compressor is placed in the outdoor unit of the split floor air conditioner, and the corresponding main control board is installed in the outdoor unit. , separated from the outdoor fan through the middle partition, the indoor unit and the outdoor unit communicate through the current loop communication circuit, and because the communication line is attached to the AC power line, it is easy to cause high voltage damage, line interference and slow transmission speed; moreover, the circuit The structure is more complex, for example: both indoor and outdoor units need to be equipped with switching power supply circuits to provide operating voltage for the main control board, relays, etc.; both indoor and outdoor units need to be equipped with power supply main relay circuits, the overall cost is high and assembly is inconvenient

[0003] Therefore, how to reduce the production cost of the product and improve the production efficiency while solving the electronic control safety problem caused by the overcurrent or overvoltage of the split floor air conditioner has become a technical problem to be solved urgently.
