Description
Technical field
The utility model relates to level sensor technical field of processing equipment, is specifically related to a kind of water level sensor of washing machine air-tightness detection device.
Background technology
Water level sensor of washing machine is used for the change of sensed water level, and the air pressure produced when its principle is and utilizes water level to rise is delivered on sensor by pipeline, and magnetic core movement change in coil magnetic flux is realized.As the standard universal part of on washing machine, the principle of existing level sensor is all substantially identical, and its theory structure is as follows: divide inner/outer tube by washing machine tub, urceolus has an independent air chamber, aqueous phase in this air chamber and urceolus connects, and keeps water level at grade; The top of air chamber is received on the valve of level sensor by seal tube.When the height of water level in washing machine drum changes, water level in independent air chamber on urceolus also changes thereupon, be sealed in the air pressure to one section of sealing air of sensor diaphragm bottom in urceolus independent air chamber water surface top, O-ring seal flexible pipe, change along with the SEA LEVEL VARIATION in laundry machine barrel.At sensor internal, the diaphragm in sensor is raised by the air pressure that sealing air section provides.Diaphragm in sensor there is a magnetic core support, magnetic core support has a magnetic core, outside magnetic core, be with a coil, magnetic core has one be installed in spring that set screw on housing compresses; When diaphragm is raised, so spring is under pressure and is compressed; When the pressure that diaphragm is lifted to sealing air section and provides equals the elastic force of spring, reach a balance, now magnetic core has a position relative to coil, and coil then can export a frequency values to computer board of washing machine; By above conversion, computer board of washing machine just can judge the water level height of washing machine.
Along with improving constantly of washing machine automaticity, the requirement for all parts of washing machine is also more and more higher.Need constantly to improve, to adapt to the requirement of this change to the equipment of each parts of processing.During as detected level sensor inside impermeability, traditional method employing is manually held level sensor and is then detected, and workload is large, and efficiency is low.
Utility model content
It is simple that technical problem to be solved in the utility model is to provide a kind of structure, easy to operate water level sensor of washing machine air-tightness detection device.
