Dishwasher air-out mechanism driving device

Abstract

The invention discloses a driving device of a leaving air mechanism of a dishwasher, which is positioned on a leaving air chamber with a leaving air channel which is communicated with an inner chamber and an exhaust chamber, the leaving air channel is provided with a cover plate which can close and open the leaving air channel, wherein, the cover plate is provided with a rotating shaft. The driving device is fixed on one end of the rotating shaft of the exhaust chamber, controls the cover plate to close and open the leaving air channel, and comprises a transmission mechanism with a gear rack and a gear intermeshing each other and a wax motor, wherein, the gear rack is arranged on a piston pole of the wax motor, the gear is arranged on one side of the rotating shaft which is corresponding to the wax motor, the gear rack and the gear intermesh. The wax motor transforms linear motion into shaft rotating motion to drive the rotating shaft to move and controls the cover plate to close and open the leaving air channel. The driving device of the invention is simple in structure and convenient for maintaining with low cost and long life.

Description

technical field [0001] The invention relates to a dishwasher, in particular to a driving device for an air outlet mechanism of a dishwasher, in particular to a driving device for an air outlet mechanism of a dishwasher driven by a wax motor. Background technique [0002] During the washing process of the dishwasher, in order to prevent the water in the inner tank from leaking out, the inner tank of the dishwasher is sealed from the outside atmosphere through the door body. During the washing process, the temperature in the inner tank of the dishwasher will rise to a certain extent, and the pressure in the inner tank will increase, especially in the process of heating and washing, the pressure in the inner tank will rise more obviously. Reducing the pressure in the inner tank will not only affect the water circulation of the dishwasher and reduce the washing effect, but also may cause safety accidents due to the excessive pressure in the inner tank. At the same time, the dis...

AI Technical Summary

Problems solved by technology

Although the above-mentioned device is driven by a wax motor, the block is set in the passage for a long time and is deformed due to friction or water vapor immersion. After deformation, it is difficult for the wax motor to retract the block, or the sealing performance of the friction block decreases. Replacement It is inconvenient to maintain, and it adopts the way of draining and exhausting separate channels, which has a complicated structure
