Washing machine with infrared switch and dewatering control method for same

Abstract

The invention discloses a washing machine with an infrared safety switch. The washing machine comprises a rectangular box body, wherein a combination of an inner drum and an outer drum is disposed in the box body; a program controller is disposed in the box body; the infrared safety switch is disposed on the inner wall of the box body and comprises an infrared emitting unit and an infrared receiving unit; the infrared emitting unit and the infrared receiving unit are disposed on two adjacent side faces of the inner wall of the box body respectively; the infrared emitting unit and the infrared receiving unit are located on the same horizontal plane and disposed in opposite directions; and the distance between the straight line on which the infrared emitting unit and the infrared receiving unit are located and the outer wall of the combination of the inner drum and the outer drum is 15-40mm at an initial state. The invention also discloses a dewatering control method for the washing machine. The method comprises a self-checking step and an initialization step, wherein deflection situations of the combination of the inner drum and the outer drum are detected continuously during dewatering; and corresponding adjustment treatments are conducted according to detection results. Through application of the washing machine and the method disclosed by the invention, different safety switches do not need to be designed for washing machines with different models; the safety switch has small errors and can be installed and adjusted easily; the corresponding treatments can be conducted automatically according to the deflection situations; and high-frequency collision noise can be avoided.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a washing machine and a dehydration control method thereof. Background technique [0002] The existing pulsator washing machine monitors the eccentric load of the washing machine tub, using a mechanical structure type safety switch arranged on the surface frame. When the eccentric load of the inner tub of the washing machine is too large, when the lever of the safety switch moves to a certain distance, the copper sheet contact linked with the lever leaves the fixed end contact, thereby disconnecting the circuit and preventing the eccentric load of the laundry in the washing machine inner tub from being too large Running caused the washing machine to move too much. [0003] However, the disadvantages of this mechanical structural control method are as follows: (1) The safety switches of washing machines with different capacities and different models are usually not u...

Problems solved by technology

[0003] However, the disadvantages of this mechanical structural control method are: (1) The safety switches of washing machines with different capacities and different models are usually not universal

(2) The stroke of the safety switch with mechanical structure is difficult to adjust, and the cumulative error is large

When the eccentric load exceeds the limit by a small amount, even if the rotation of the inner barrel can produce the effect of automatic deviation correction, water must be refilled to adjust the eccentric load, which will inevitably waste time, water and electricity
