Technical field
The utility model relates to the water level switch that uses on the washing machine, carries out many gears washing machine water level pressure switch of control automatically on specifically a kind of washing machine.
Background technology
Relevant by retrieval patent documentation does not retrieve the washing machine water level pressure switch identical with the utility model structure at present as yet.Along with improving constantly of people's living standard, washing machine has been widely applied to huge numbers of families as the main electrical equipment of a kind of family.Along with technology is constantly progressive, the automaticity of washing machine is more and more higher, also brings great convenience to us.The existing many gears that are used for carrying out on the single container washing and extracting machine water level control are controlled water level pressure switch automatically; though can play to water level control and automatically actuated function; but because structural reason makes it comparatively complicated, and the washing machine water level is too high to cause overflowing the water phenomenon along with the continuous variation of water level usually can occur when starting automatically after water level arrives certain position.In order to overcome the too high casual water phenomenon of bringing of water level, thus be necessary existing level control switch for water is improved, to satisfy the requirement of single container washing and extracting machine work better.
Summary of the invention
The purpose of this utility model is that a kind of improvement on existing washing machine water level pressure switch basis will be provided, and has compact conformation, can realize many gears pressure washing machine water level pressure switch of control automatically.
Technical characterictic of the present utility model is: on the basis of considering compact conformation, control automatically, be designed to regulate bolt, spilling water pumping source inserted sheet pressure and regulate the washing machine water level pressure switch that bolt, washing machine power contact head, spilling water pumping source inserted sheet are formed by housing, diaphragm, barrier film supporting plate, main reed, moving plate, main reed back-moving spring, moving plate return spring, moving plate pressure, be provided with diaphragm in housing, described diaphragm is arranged on the barrier film supporting plate; The inner chamber of the lid of diaphragm and housing forms air chamber, is provided with main reed on the housing seat of housing, is provided with main reed back-moving spring on main reed; Be provided with moving plate on the housing seat of housing, described moving plate is regulated bolt by moving plate pressure and is carried out the pressure adjusting, and moving plate is contacted with the contact jaw of barrier film supporting plate; Moving plate pressure is regulated bolt and is arranged on the housing seat of housing; On the housing seat of housing, be respectively equipped with washing machine power contact head, spilling water pumping source inserted sheet; Described spilling water pumping source inserted sheet pressure is regulated bolt and is arranged on the housing seat of housing.
Described housing is made up of housing seat, lid, is provided with air inlet in the lid, and described air inlet is parallel with the end face of lid; The case of described housing for adopting flame retardant plastics to make.
The flexible sheet of described diaphragm for adopting flame retardant rubber to make.
Described moving plate is made up of barrier film supporting plate location, spilling water pumping source contact, and the barrier film supporting plate is orientated the groove that the contact jaw with the barrier film supporting plate matches as.
The elasticity spring body that described main reed back-moving spring is an a pair of pagoda shape.
It is the version with location cone in the end that described moving plate pressure is regulated its positioning end of bolt.
Described spilling water pumping source inserted sheet pressure is regulated bolt and is formed by regulating bolt, spring, movable push bar, regulates bolt and is connected with housing seat in the housing, and the adjusting bolt promotes movable push bar by spring.
During work, when washing machine need be gone up water, open water intaking valve, the washing machine bucket water level constantly rises, endotracheal air constantly pours in the lid of housing and the air chamber that diaphragm forms, and air is compressed, when bucket water level continues to rise, gas promotes diaphragm and expands, and promotes main reed and moving plate moves by the barrier film supporting plate; Along with the mobile of barrier film supporting plate makes the normally-closed contact in the main reed separate with power supply, water intaking valve is closed, the contact in the main reed is contacted with the washing machine power contact head, washing machine is started working; When bucket water level further increases, along with the pressure in the tracheae increases, gas pressure in the air chamber that the lid of housing and diaphragm form is further increased, the barrier film supporting plate is moved, and the spilling water pumping source contact in the moving plate is contacted with spilling water pumping source inserted sheet, this moment, the spilling water pump was started working, and spilling water is in time got rid of.Be provided with moving plate pressure in the housing and regulate bolt, purpose is for convenience the pressure of moving plate to be regulated and is provided with; The positioning end that moving plate pressure is regulated bolt is designed to have the version of locating cone in the end, its objective is in order to increase spring length, and increase the spring pressure adjustable range, the location of playing simultaneously spring is provided with.Spilling water pumping source inserted sheet pressure is regulated bolt design and become to have the version of movable push bar, its objective is to having more insulating effect, and is safer and be provided with.
The utility model has the advantages that: because housing adopts flame retardant plastics to make, thereby improved performance, made product safer; Because the air inlet in the lid of housing is parallel with the end face of lid, thereby make the interior gas of air chamber even; Because moving plate is designed to Z-shaped structure, and be provided with groove shape barrier film supporting plate location, thereby make moving plate have more elasticity, be convenient to the location, contact point is more reliable; Because main reed back-moving spring is designed to two pagoda shape versions, makes spring bigger, and is safe and reliable; Because moving plate pressure is regulated the version that bolt design becomes location cone in the end, and adopts the moving plate return spring to compress, thereby make compact conformation, increased spring length, make the spring pressure adjustable range bigger; Adopt the adjusting bolt to combine because the spilling water pump pressure is regulated bolt, thereby have more insulation effect, make product safer with movable push bar; Because rational in infrastructure, compact, automaticity is high, so very big practical and popularizing value is arranged.
