Rotary type air exchange piston for window type air conditioner

Abstract

The invention relates to the technical field of air conditioning, in particular to a rotary ventilating piston of a window air conditioner which is used for adjusting indoor ventilation, solves the problems of uncontrollable ventilation and easy damage of existing ventilating pistons, and adopts following technical proposal: the rotary ventilating piston is arranged on a base plate of the window air conditioner and separates the window air conditioner into an indoor part and an outdoor part, and a clapboard between an air vent and a guide frame is arranged on the inner right lateral surface of the window air conditioner; the ventilating piston can be plugged into and out from the air vent, and has one end that is connected with an inner lateral surface of the ventilating piston and supportably guided by the guide frame and the other end which perforates a control bar that is arranged in a perforated orifice in the upper right part of a front panel of the window air conditioner. The rotary ventilating piston of the window air conditioner is characterized in that the air vent is a round spiral through hole, the ventilating piston is a hollow double-screw bolt plug that has matched screw threads with the air vent, through holes that are used for air ventilation are arranged in peripheral spiral grooves, an inner closed end of the hollow double-screw bolt plug is connected with one end of the cylindrical control bar, while the other end of cylindrical control bar is supported and guided by the guide frame and extends from the perforated orifice in the upper right part of the front panel of the window air conditioner.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a rotary ventilation piston of a window type air conditioner for adjusting indoor ventilation volume. Background technique [0002] Generally speaking, an air conditioner is a space installed in a vehicle, office, home, etc., to cool or heat the indoor air. It is mainly composed of compressors, outdoor heat exchangers, expansion valves, and indoor heat exchangers. The refrigerant circulation system composed of and the air circulation system composed of air inlet and outlet, grille, fan and fan motor, and air guide. [0003] Air conditioners can be divided into split air conditioners with indoor and outdoor separation and integrated air conditioners with indoor and outdoor integration. Split air conditioners can be divided into wall-mounted, ceiling-mounted, and cabinet types according to different installation forms . Integrated air conditioners are divided into window...

Problems solved by technology

[0006] Existing window air conditioner ventilation structure, such as application number 200510122170.8 window type air conditioner ventilation lever structure and application number 200610129333. A rectangular ventilation hole is designed on the top, and a ventilation piston is designed at the end of the folded or stretched control link, and the part outside the through hole at the upper right part of the front panel of the window air conditioner is pushed and pulled by the connecting rod to control the ventilation. The air piston opens and closes the air exchange hole for air exchange, but the above-mentioned existing air exchange piston structure cannot adjust the air exchange volume, and the piston reciprocating stretching friction is easy to loosen, fall off and be damaged, and the service life is short, thus affecting indoor and outdoor. The airtightness and ventilation function of the partition
