Abstract
The utility model discloses a detergent pumping device for a washing machine and relates to a detergent pumping device. The detergent pumping device comprises a U-shaped rubber tube (1), a liquid inlet straight rubber tube (2), a liquid outlet straight rubber tube (3), a first one-way valve (4), a second one-way valve (5) and a gear pump (6). The liquid inlet straight rubber tube (2) is connected with one end of the U-shaped rubber tube (1) through the first one-way valve (4), the other end of the U-shaped rubber tube (1) is connected with the gear pump (6), and the gear pump (6) is connected with the liquid outlet straight rubber tube (3) through the second one-way valve (5). The detergent pumping device is simple in structure and improves the reliability of an automatic feeding system.
Description
Technical field
The utility model relates to a kind of detergent pump liquid device, be specifically related to a kind of laundry detergent liquid pumping device.
Background technology
The at present washing machine of automatic detergent adding use is more and more general, but the reliability of some automatic switching playing function is relatively poor, especially adopts gear pump as the automatic switching place system of liquid pumping device.Conventional pump liquid mode is: the pump housing passes through directly direct extracting liquid from sink of woven hose, then is delivered in the apparatus for combining liquids by woven hose.When user's long period was stopped using the automatic switching playing function, residual washing agent can evaporate by liquid-transport pipe-line and sink, thereby causes being in the pump housing dry state.If the pump housing is when adopting gear pump, can cause gear pump can't again extract washing agent, thus so that washing machine forfeiture automatic switching playing function.Can bring very large inconvenience to the user like this.
The utility model content
For the deficiency that exists on the prior art, the utility model purpose is to be to provide a kind of laundry detergent liquid pumping device, and is simple in structure, improved automatic switching place system reliability.
To achieve these goals, the utility model is to realize by the following technical solutions: the laundry detergent liquid pumping device, comprise U-shaped sebific duct, the straight sebific duct of feed liquor, the straight sebific duct of fluid, the first check valve, the second check valve and gear pump, the straight sebific duct of feed liquor links to each other with U-shaped sebific duct one end by the first check valve, the U-shaped sebific duct other end links to each other with gear pump, and gear pump links to each other with the straight sebific duct of fluid by the second check valve.
The utility model is when the long-term automatic detergent adding function on the shelf of user, even the residual liquid in the sink all evaporates, can not cause evaporating in the gear pump yet, thereby the meshing gear surface in the assurance pump is full of liquid all the time, keep lubricating status, thus the system of assurance reliability service.
Of the present utility model simple in structure, greatly improved automatic switching place system reliability.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
With reference to Fig. 1, this specific embodiment is by the following technical solutions: the laundry detergent liquid pumping device, it comprises U-shaped sebific duct 1, the straight sebific duct 2 of feed liquor, the straight sebific duct 3 of fluid, the first check valve 4, the second check valve 5 and gear pump 6, the straight sebific duct 2 of feed liquor links to each other with U-shaped sebific duct 1 one ends by the first check valve 4, U-shaped sebific duct 1 other end links to each other with gear pump 6, and gear pump 6 links to each other with the straight sebific duct 3 of fluid by the second check valve 5.
The course of work of this specific embodiment is: when washing machine begins to start program for washing, under the effect of gear pump, washing agent flows into the straight sebific duct of feed liquor from liquid storage box, and enter U-shaped sebific duct 1 by the first check valve 4, export the second check valve 5 to through behind the gear pump, be transported in the liquid diluting box by the straight sebific duct 3 of fluid at last.The first check valve 4 places the prime of U-shaped sebific duct 1, and washing agent cannot be back to the straight sebific duct 2 of feed liquor after flowing to U-shaped sebific duct 1, so that be full of all the time liquid in the U-shaped sebific duct 1.When washing machine during normal the use, pressure is larger during water inlet, running water easily is back in the straight sebific duct 3 of fluid by the liquid diluting box, because the second check valve 5 places gear pump 6 to go out the prime of sap cavity, running water can't flow to the sap cavity that of gear pump 6, so that the pressure of the admission chamber of gear pump 6 is higher than sap cavity all the time, gear pump 6 can work.
Can form approximate airtight space between this specific embodiment the first check valve 4 and the second check valve 5, thereby guarantee there is liquid in U-shaped sebific duct 1 and the gear pump 6 always, gear pump 6 can not lose efficacy because not working for a long time.When the long-term automatic detergent adding function on the shelf of user, even the residual liquid in the sink all evaporates, can not cause evaporating in the gear pump yet, thereby guarantee that the meshing gear surface in the pump is full of liquid all the time, keep lubricating status, thus the system of assurance reliability service.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
