Description

Mounting structure for water level pressure sensing of washing machine Technical Field The utility model relates to the technical field of cleaning equipment, in particular to a mounting structure for water level pressure sensing of a washing machine. Background Currently, in the washing machine industry, a water level sensor is generally arranged, a detected water level signal is transmitted to a control end by the water level sensor through a signal wire, and the control end controls the opening and closing of a water inlet valve according to the received signal. Among the prior art, publication number is CN212560805U, and the patent name is a washing machine water level sensor, discloses a washing machine water level sensor, including the casing, with the detection zone of washtub intercommunication, be connected with the trachea in the detection zone, the trachea is connected with the sensor air chamber, the sensor air chamber is located the washtub top, the trachea towards after extending to the washtub bottom sensor air chamber extends. The air pipe is arranged in the detection area, and then the air pipe is extended downwards and then is extended upwards to the sensor air chamber, so that the air pressure change detected by the sensor air chamber is the air pressure change generated by adding water, and the detection precision of the water level sensor is improved. The water is added in a certain amount to generate a certain amount of water pressure, and the certain amount of water pressure is generated to enable a certain amount of air in the detection area to enter the air pipe to generate a certain amount of air pressure, so that the sensor air chamber detects the air pressure change value and feeds back the air pressure change value to the corresponding signal of the controller. In the prior art, the air chambers for collecting air pressure changes are generally integrally injection molded on the side wall of the cleaning cylinder body, so that the die is complex, the manufacturing cost is high, and the connecting holes of the air chambers for connecting air pipes are protruded outside the cleaning cylinder body, and the aperture is small, so that the defect easily occurs in the injection molding process, the yield is low, the whole cylinder body is scrapped due to collision damage of a convex structure easily in the carrying process, the single product loss is large, and the maintenance cost is high.
