Abstract
The utility model relates to a dishwasher used water level switch, in particular to a home dishwasher used water level switch and a water overflow switch. A container is provided with an opening on the upper part, and the back face thereof has a protruding hole consistent with the inner container of the machine, the left and right sides of the container are respectively provided with a protruding part with holes on the upper part, the inside of the protruding part is an empty shell body, a floating body with a connecting rod is ranged therein, the connecting rod contacts a touch of the microswitch fixed on the container. Because the convergence of the water level switch and the water overflow switch, production cost is saved, maintenance is easy, incorrect operations are reduced, the corrosion to the parts when water flowing into the lower tray can be avoided, the problem of hard cleaning is solved, and space is saved.
Description
The utility model relates to a kind of use in dishwasher water level switch, refers to water level switch and spilling water switch that domestic bowl-washing is used especially.
As everyone knows, the water level of domestic bowl-washing control now is to utilize at one section air chamber of water tumbler place formation, change pressure change in the air chamber by the height of water level, a baroswitch communicates with air chamber by a pipeline, promotes baroswitch work and stop into water when water level reaches.Spilling water protection is a mechanism independently in addition; the water pipe that one projection is arranged on the inner bag of machine; the a little higher than normal water bit position of the mouth of pipe; the outlet of pipe communicates with pallet under the casing; when water level was too high, water just entered pallet under the casing by water pipe, along with the rising of pallet water level down; make fixing buoyancy switch work on following pallet, make machine stop washing and keep hull-borne.Because baroswitch is subject to the influence of extraneous factor; maloperation appears easily; spilling water protection complex structure; if action makes water enter down pallet, cleaning is got up and is quite bothered, and also can damage the electric and mechanical part close with base plate in the dish-washing machine; this system is that stand-alone configuration takes up room; and independent tubes is arranged, cause the waste of resource, produce very inconvenience when safeguarding.
The purpose of this utility model is to release a kind of novel use in dishwasher water level device, and it has solved dish-washing machine in the past independently water level device and overflow device, and the complex structure volume is big, maloperation easily, the problem that cost is high.
The purpose of this utility model is to realize like this, container at a upper opening, there are one and the corresponding to protruding hole of machine inner bag perforate in the back side, the projection that a top perforate is each side arranged of container, in the projection is hollow shell structure, there is the buoyancy aid of a band connecting rod inside, and the microswitch contact that connecting rod and is fixed on the container is close.
There is a cylindrical nuts to revolve thereon on the top of connecting rod.
The utility model has been saved production cost because water level switch and spilling water switch unite two into one, and has made things convenient for maintenance, make water level control more direct more obvious, reduced the maloperation of device, avoided water to flow into pallet etching machine spare down, solve the problem of cleaning inconvenience, saved the space.
The cylindrical nuts on connecting rod top can regulate water level easily, made things convenient for the user owing to body is placed the problem that water level switch that unequal reason causes need be finely tuned.
Below in conjunction with accompanying drawing a specific embodiment of the present utility model is described in detail:
The drawing explanation:
Fig. 1 is the positive half sectional view of a specific embodiment of the utility model.
Fig. 2 is the side view of a specific embodiment of the utility model.
One and the corresponding to protruding hole 2 of machine inner bag perforate are arranged at container 1 back side of a upper opening, the projection that a top perforate is each side arranged of container 1, in the projection is hollow shell structure, there is the buoyancy aid 7 of a band connecting rod 3 inside, and the microswitch contact 5 that connecting rod 3 and is fixed on the container 1 is close.Water enters the inside of container 1 from the projection 2 of container 1 bottom when water inlet, rising along with the water inlet water level, water enters the right projection by the aperture of the right projection, gradually high water level raises buoyancy aid 7, move on the connecting rod 3 of promotion and buoyancy aid 7 one, have one to be fixed on microswitch 6 on the projection 9 of container 1 by bolt 8 directly over the connecting rod 3, move on on the connecting rod 3 and promote fine motion contact 5, microswitch 6 actions make machine stop into water.When this malfunctioning switch, water level raises gradually, makes the higher microswitch of left position 6 action, makes the machine maintenance hull-borne that quits work.When other reasons need change water inlet water level and spilling water water level, the cylindrical nuts 4 on can turn bar 3 changed the distance of bar 3 and contact 5.
Claims (2)
1. use in dishwasher water level switch, comprise container, ball float, microswitch is characterized in that the container at a upper opening, and there are one and the corresponding to protruding hole of machine inner bag in the back side, the projection that a top perforate is each side arranged of container, in the projection is hollow shell structure, and there is the buoyancy aid of a band connecting rod inside, and the microswitch contact that connecting rod and is fixed on the container touches mutually.
2. container as claimed in claim 1 is characterized in that a cylindrical nuts is arranged at the connecting rod top of container.
