Description
Technical field
The utility model belongs to washing machine manufacturing technology field, particularly relates to a kind of waterproof and remains hopper device.
Background technology
Existing roller washing machine generally has hopper device, and this hopper is in the middle of entering water electromagnetic valve door and washtub, and hopper is connected with washtub by main water inlet tube, and hopper arranges atmospheric air open port usually, to ensure to balance with ambient pressure in cylinder.The water inlet water route of this spline structure, due to atmospheric air open port, just loses water flow pressure time water enters washtub.But some function ratio of nearest washing machine such as door and window cleaning function requires can have certain expulsion pressure when entering washtub.In order to provide this hydro-peening current, manufacturing firm often arranges a water route again outside the water route that in the past can balance with air, can spray door and window during valve open with certain pressure.But a part of water can be retained in pipeline after the closed electromagnetic valve in this water route, after this resident water remains certain hour, may bacterium be produced, cause laundry next time to pollute.
When tap water supply system is cut off the water, the tap water pipe network staying in the user of higher floor will become negative pressure, if washing machine is washed clothes at that time, the residual water of the water then in washing machine drum and hopper playpipe inside is then likely drawn back tap water pipe network by this injection line, causes pipe network to pollute.
Summary of the invention
The injection water route that the utility model will solve existing hopper device electromagnetic valve close stop water inlet after outlet conduit there is residual water can not be emptying and the problem of anti-siphon effect cannot be played, provide waterproof of the present utility model to remain hopper device for this reason.
For solving the problem, the technical solution used in the present invention comprises hopper and upper cover, described hopper have atmospheric air open port and main delivery port, cover on described and be provided with water inlet and delivery port, cover on described and be also provided with special-shaped convex tendon, the flow-guiding channel formed after capping is arranged on special-shaped convex tendon, it is characterized in that in the abnormity convex tendon of described water inlet side, being provided with a through hole at described upper cover, this through hole one end is communicated with described delivery port, and the other end is communicated with hopper.
Described through hole is established an one-way cock, by capping projection, one-way cock is fixed in through hole.
Described one-way cock comprises spool, rubber seal and spring.
The beneficial effects of the utility model are when water inlet is intake, through hole internal check valve door makes the unidirectional blocking of through-hole passage by hydraulic pressure effect, running water can not flow to hopper by through hole, and flow to jet only by delivery port, when stopping when intaking, in injection line, pressure is lost, one-way cock caulking gum leaving channel under the action of the spring, passage is opened, air in hopper can enter injection line through through hole, water in injection line like this can flow out from jet under the effect of inertial flow, does not remain in injection line inside.
When being negative pressure in tap water pipe network, when negative pressure can be delivered in playpipe by electromagnetic valve, one-way cock hopper lateral pressure is greater than the pressure of playpipe trackside, one-way cock is opened, air can flow to playpipe inside, thus reduce negative pressure or destroy the effect of negative pressure, prevent aqueous reflux in playpipe to tap water pipe network.

Mark in figure: 1 hopper, 101 atmospheric air open ports, 102 main delivery ports, 2 upper covers, 201 water inlets, 202 delivery ports, 203 special-shaped convex tendons, 204 through holes, 3 cappings, 301 cappings are protruding, 4 one-way cocks, 401 spools, 402 rubber seals, 403 springs.
Detailed description of the invention
Embodiment one
The Anti-drip hopper device of the present embodiment, as shown in Figure 1 and Figure 2, comprise hopper 1 and upper cover 2, described hopper have atmospheric air open port 101 and main delivery port 102, cover on described and be provided with water inlet 201 and delivery port 202, cover on described and be also provided with special-shaped convex tendon 203, the flow-guiding channel formed after capping 3 is arranged on special-shaped convex tendon, it is characterized in that in the abnormity convex tendon of described water inlet side, being provided with a through hole 204 at described upper cover, this through hole one end is communicated with described delivery port, and the other end is communicated with hopper.
When import water is intake, can water outlet in through hole, delivery port also can water outlet, when stopping when intaking, enters air, by the water in emptying flow-guiding channel in through hole.
Embodiment two
The Anti-drip hopper device of the present embodiment, as shown in Figure 3, described through hole is established an one-way cock 4, is fixed in through hole by capping projection 301 by one-way cock, described one-way cock comprises spool 401, rubber seal 402 and spring 403.Other structure is with embodiment one.
When water inlet is intake, by the hydraulic pressure in flow-guiding channel, spool is moved downward, rubber seal on Compress Spring, spool seals up through hole, goes out water seal under making through hole, only has delivery port water outlet, when stopping when intaking, hydraulic pressure in flow-guiding channel disappears, and spring reset is to A-stage, and through hole is opened, air is entered, by the water in emptying flow-guiding channel in through hole.
