Description

Technical Field

[0001] The utility model relates to the technical field of a washing machine door magnetic switch, and more specifically to a fixing structure for a washing machine door magnetic switch. Background Art

[0002] The door magnetic switch of the washing machine is a safety device, which mainly plays a protective role. It uses magnetic field for control. When the door cover is closed, the magnet will attract the contact inside the door magnetic switch, thereby connecting the control circuit and starting the washing machine. On the contrary, if the door is not completely closed, the washing machine will stop running immediately. The main components of the door magnetic switch include the magnet and the magnetic switch on the computer board. For pulsator washing machines, it is necessary to check whether the magnet on the door cover has fallen off; for drum washing machines, it is necessary to check whether the door lock is damaged. In addition, the connection problem of the magnetic detection switch may also cause failure.

[0003] The main function of the door magnetic switch setting of the washing machine is to ensure that the door of the washing machine is tightly closed during operation, so as to prevent the door from opening suddenly during operation, causing water, clothes or other internal parts to splash or pop out, which may cause harm to the user. If the door magnetic switch is not fixed properly, its position may change due to vibration or movement, thereby affecting the correspondence between it and the magnet. Since the washing machine may generate vibration and impact during use, if the door magnetic switch is not fixed properly, it may be damaged by these external factors, which may cause the washing machine to be unable to detect whether the door is closed normally, thereby affecting its normal operation.

[0004] Therefore, there is a lack of a fixed structure for the door magnetic switch of the washing machine, which can improve the safety and functionality of the door magnetic switch of the washing machine. The door magnetic switch can be firmly installed on the washing machine through the fixed structure, which can ensure that it can work stably and reliably under any circumstances.
