Window type air-conditioner air exchanging valve automatic opening-closing device

Abstract

The invention relates to an automatic opening and closing device of a window type air conditioner scavenging valve. The automatic opening and closing device comprises a scavenging valve and a scavenging rod, wherein, the scavenging valve is composed of a valve body and a valve base, the scavenging rod is penetrated through an air guiding device of the window type air conditioner, and one end of the air guiding device is connected with the valve body of the scavenging valve; the automatic opening and closing device also comprises a stepping motor, a display control circuit board, a connecting rod and a slide way, wherein, one end of the stepping motor is connected with the display control circuit board and is controlled by the display control circuit board, the other end of the stepping motor is connected with the connecting rod and drives the connecting rod to move, the connecting rod is a crank shaft, which is mutually connected with the scavenging rod, the scavenging rod is mutually matched with the slide way, and makes the reciprocating linear movement along the slide way. The opening and closing process is achieved by the stepping motor, the opening and closing speed is even, the stroke of the reciprocating movement of the scavenging rod is fixed, the damage possibility of the scavenging rod is reduced through the guide of the movement of the scavenging rod by the slide way, the service life of the scavenging rod is prolonged, when the scavenging valve is opened and closed, the operation is simple, the use is convenient, and the controlling degree of the complete air conditioner is higher.

Description

technical field [0001] The invention relates to the technical field of a check valve with a guide rod for a window air conditioner, in particular to an automatic opening and closing valve for a window air conditioner that can be driven by a stepping motor to automatically open and close the ventilation valve. close the device. Background technique [0002] Generally, an air conditioner is a device for cooling or heating an indoor environment to create a comfortable indoor environment, and is roughly classified into an integrated type air conditioner and a split type air conditioner. [0003] Although the functions of the integrated air conditioner and the split air conditioner are the same, the integrated air conditioner is equipped with cooling and heat dissipation components in the same casing, and is installed on the wall or on the window through the wall, while the split air conditioner The air conditioner is provided with a refrigeration device on the indoor unit, and ...

Problems solved by technology

[0012] In the prior art, the indoor and outdoor air exchange needs to rely on the manual push-pull operation of the air-exchange lever. When manually pushing and pulling, the force is unbalanced, the direction of force cannot be guaranteed accurately, and it is easy to use too much force. After multiple air-exchange operations, it is easy to It causes wear and tear on the air exchange rod, shortens the service life of the air exchange rod, and it is difficult to replace parts after the air exchange rod is damaged.
