Air conditioner and door panel moving device thereof

Abstract

The invention discloses an a door panel moving device of an air conditioner and the air conditioner with the door panel moving device. The door panel moving device comprises a moving component box, a rack mounted in the moving component box, a drive device for driving the rack to move, a rolling device and a guide rail, wherein the rolling device is rotationally mounted on the rack and comprises a rolling shaft and a rolling bearing, the rolling bearing rotationally sleeves the rolling shaft, and the guide rail is mounted on the moving component box for guiding the move of the rolling bearing. According to the door panel moving device, the rotary rolling bearing is mounted between the rack and the moving component box, so that the relative movement between the rack and the moving component box is changed into rolling friction; because the rolling bearing is mounted on the rack, the situation that both the upside and the downside of the rolling bearing are extruded is avoided, and the rolling bearing can always roll in the rack movement process. By means of said mode, the extrusion jamming problem due to the irregular rack surface and moving component box surface is effectively avoided, and the service life of the door panel moving device is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and a door panel moving device thereof. Background technique [0002] Cylindrical air conditioners are gradually being widely used because of their space-saving and novelty. [0003] When the cylindrical air conditioner is in use, it is necessary to open the door panel to expose the air outlet, and then perform the air conditioning function of the air conditioner. The movement of the door panel of the cabinet machine of the existing cylindrical air conditioner is mainly controlled by the motor, specifically, the gear is engaged with the rack of the moving part for transmission, and the rack and the moving part box of the moving part are set The balls before the two are rollingly connected, and the balls move under the guidance of the arc track on the moving part box, so that the gear drives the rack to move on the moving part box to open the door pane...

AI Technical Summary

Problems solved by technology

[0004] However, since the rack and the moving part box have relatively low surface precision requirements during processing, protrusions or grooves are likely to exist on the surface of the rack and the surface opposite to the moving part box

When at least one of the surface of the rack and the surface of the moving part box has a protrusion, the distance between the two becomes smaller, which in turn squeezes the balls placed between the two, causing the balls to be squeezed too much to Rolling means that the balls are stuck and the rolling friction becomes sliding friction, which increases the resistance. After long-term operation, there are moving parts malfunctioning and the service life is reduced.
