Description
Technical field
The utility model relates to a kind of washing machine, refers in particular to a kind of improvement to the washing machine water level switch.
Background technology
Enter when 21 century, the arid of global range takes place again and again, and serious water resources crisis is threatening the development of human existence and society.In the whole world, serious, the many rivers of many area arids are dry, water and soil resources run off in a large number, urbanite water consumption seriously is in an emergency.Meanwhile, Chinese domestic lack of water situation is also more and more serious, and many cities have begun limitation water-feeding.Therefore, water-saving type laundry machine has been the important trend and the direction of world's washing machine industry development.
Summary of the invention
The purpose of this utility model is to design a kind of multistage water level pressure switch of automatic washing machine, when utilizing this water level switch to control the water level of washing machine, can save the used water yield to greatest extent.
Its main technical schemes is to utilize diaphragm of rubber that the inner chamber of shell is divided into two parts in the enclosure, wherein a part is an air chamber, another part is installed supporting plate and spring leaf, on supporting plate, connect push rod, sleeve spring on push rod, upper end at shell connects micrometer adjusting screw, the lower end of micrometer adjusting screw contacts with the regulating water level pressing plate, spring contacts with the lower plane of regulating water level pressing plate, one end of regulating water level pressing plate is connected on the shell, the other end contacts with cam on being installed on the regulating water level handle, it is characterized in that at the cam curve that is provided with at least on the cam more than 4 sections.
Mounting plate on described shell, the regulating water level handle is installed on the fixed head; The valve that is communicated with air chamber is set on the pairing shell of air chamber; Movable contact is set on spring leaf, normally closed contact is set on the shell corresponding to the movable contact position and often opens contact; Weeper is set on shell.
6～12 sections cam curves can be set on described cam, or 8～10 sections cam curves.
The utility model has the advantages that because at the cam profile that is provided with on the cam more than at least 4 sections, compare with the original 4 sections cam profiles that have only, increased alternative water level, so the user can select required water level according to actual needs, thereby save slurry.

The specific embodiment
As shown in the figure: in shell 8, utilize diaphragm of rubber 3 that the inner chamber of shell 8 is divided into two parts, wherein a part is an air chamber 2, supporting plate 10 and spring leaf 9 are installed in another part, on supporting plate 10, connect push rod 17, sleeve spring 6 on push rod 17, upper end at shell 8 connects micrometer adjusting screw 18, the lower end of micrometer adjusting screw 18 contacts with regulating water level pressing plate 13, spring 6 contacts with the lower plane of regulating water level pressing plate 13, one end of regulating water level pressing plate 13 is connected on the shell 8, the other end contacts with cam 14 on being installed on regulating water level handle 16, at the cam curve that is provided with at least on the cam 14 more than 4 sections.
When the water level in the washing machine rises, the gas dome air that is in the washing machine drum body bottom is compressed, pressure rises, Pneumatic pipe cleaner is crossed in the air chamber 2 that tracheae is delivered to water level controller, when reaching required water level, air pressure moves upward diaphragm of rubber 3, promotes push rod 17 and spring leaf 9 actions, movable contact on the spring leaf 9 and normally closed contact 4 are disconnected, and often open contact 5 closures.When beginning during exhaust, the pressure in the air chamber 2 descend, and when dropping to when resetting water level, diaphragm of rubber 3 moves down, and spring leaf 9 drives movable contacts and restores.
Rotate regulating water level handle 16, driving cam 14 rotates, just can change regulating water level pressing plate 13 contacts with the different molded lines of cam 14, thereby change the pretightning force of 13 pairs of push rods 17 of regulating water level pressing plate, that is to the pretightning force of diaphragm of rubber 3, thereby required pressure when regulating air pressure in the air chamber 2 and promoting push rod 17 is realized the adjusting to water level, and micrometer adjusting screw 18 is used for accurately regulating the pretightning force that puts on the diaphragm of rubber 3.
Mounting plate 15 on shell 8, and regulating water level handle 16 is installed on the fixed head 15.The valve 1 that is communicated with air chamber 2 is set on air chamber 2 pairing shells 8, and tracheae is connected on the valve, and pressure is passed to air chamber.
On spring leaf 9, movable contact is set, normally closed contact 4 is set on the shell 8 corresponding to the movable contact position and often opens contact 5.When static, movable contact contacts with normally closed contact, during action, movable contact with often open contact and contact.Weeper 12 is set on shell 8.6～12 sections cam curves are set on cam 14, or 8～10 sections cam curves.
