Abstract
The utility model relates to an anti-reflux water inlet pipe component used for a washing machine. The anti-reflex water inlet pipe component ensures that the structure of the washing machine is simplified and the manufacture cost thereof is lower while ensuring that the reflex can be prevented. The anti-reflex water inlet pipe component comprises a water inlet pipe body, a connecting tube valve body is inserted at one end of the water inlet pipe body, and a bent pipe structure is inserted at the other end of the water inlet pipe body. The anti-reflux water inlet pipe component is characterized in that a pressure valve which prevents water in the pipe from refluxing to a water tap is arranged inside the connecting tube valve body.
Description
(1) technical field
The utility model relates to use in washing machine pipe technology field, is specially the anti-reverse conduit assembly that flows to of use in washing machine.
(2) background technology
Its structure of use in washing machine water inlet pipe is seen Fig. 1, and it is used for the water intaking valve of automatic washing machine and being connected of water supply pipe depotition cock end, thereby washing machine and running water pipe network is communicated with and realization fully-automatic washing function.Because the water intaking valve of part washing machine is arranged on the bottom of washing machine, water level in the inner tank of washing machine is higher than water intaking valve and water inlet pipe. and in a single day in laundry processes, run into and cut off the water, can form negative pressure time vacuum in the water supply pipe, with the addle suck-back in the inner tank of washing machine in water supply network, pollute the major accident of running water pipe network system, among Fig. 1,1,9 be nut, 2 for band net sealing gasket, 3 for taking over, 4,6 being the lower seal pad for bend pipe, 8 for flexible pipe, 7 for aluminium tube sealing, 5.
(3) summary of the invention
The utility model provides use in washing machine the anti-reverse conduit assembly that flows to, and when its assurance prevents adverse current, guarantees washing machine structure simplification and lower manufacturing cost.
Its technical scheme is such, and it comprises the water inlet pipe body, and an end of described body is fitted with the adapter valve body, and the other end is fitted with bend pipe structure, it is characterized in that: described adapter valve inner is provided with and prevents to manage the pressure valve that interior aqueous reflux is gone into water tap.
It is further characterized in that: described pressure valve comprises spool, valve seat, described valve seat is installed on takes over the outer end of taking in the valve body, the outside spiral-lock of taking over has nut, be provided with sealing gasket in the described nut, described sealing gasket press-fits in taking over described outer end, between described valve seat and the described nozzle inner wall sealing ring is set, the end that spool combines with described valve seat is provided with sealing, the other end of described spool press-fits in spring, and the other end of described spring press-fits the annular bottom face in described adapter inner chamber.
In the said structure of the present utility model, being provided with of pressure (unidirectional) valve can prevent to occur in the pipeline negative pressure time vacuum state (time), prevent that the addle suck-back in the inner tank of washing machine from causing the contaminated shortcoming of running water pipe network system to water supply network.
