Abstract

The utility model relates to a water inlet filter for washing machines, which comprises an upper cover with a water inlet and a lower cover with a water outlet, the upper cover and the lower cover are fitted together, so that a cavity is formed, and a filtering unit is arranged in the cavity. The water inlet filter is characterized in that: a first projected neck which is axially projected outward and communicated with the water outlet is formed at a position on the bottom of the lower cover, which corresponds to the water outlet, a second projected neck which is arranged coaxial with the first projected neck and sleeved on the first projected neck is also formed at the position on the bottom of the lower cover, which corresponds to the water outlet, and an annular slot in which a water inlet connector of a washing machine panel can be inserted is formed between the first projected neck and the second projected neck. Compared with the prior art, the utility model improves the structure of the water outlet of the lower cover of the filter, that is, the two coaxially arranged projected necks are arranged at the water outlet, the annular slot is formed between the two coaxial projected necks, and thereby the tightness and reliability of connection are enhanced.

Description

A kind of washing machine inflow filter

Technical field

The utility model relates to a kind of filter, particularly a kind of filter that is installed on the washing machine inflow mouth.

Background technology

For the filtration washing foreign matter, reducing draining pollutes, washing machine is equipped with filter at delivery port usually, still, considers that the water quality in a lot of areas is relatively poor at present, impurity in the water is more, if directly insert such water source when using washing machine, that clothing does not only wash clean, even also can stay other spot, for purified water source, many washing machines also begin to install filter on water inlet.

In the prior art, the water inlet filter of washing machine is directly installed on the Washing Machine Panel, promptly on Washing Machine Panel, offer a through hole, a column pipeline that can insert through hole is arranged at the bottom of water inlet filter, yet do not need the occasion of filter or filter to damage under the situation of needs replacing at some, through hole on the panel can't directly be used with water inlet pipe, water inlet pipe can not be connected on the Washing Machine Panel, therefore, general water inlet filter is even also all be to be installed on the panel in the occasion that does not need to use always, in case take off into water filter, then water inlet pipe just can't be inserted in the through hole of panel, make washing machine normally to intake, cause the inconvenience in the use.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of water inlet pipe that do not influence directly to cooperate and be connected more tight washing machine inflow filter reliably with panel at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this washing machine inflow filter, comprise loam cake that offers water inlet and the lower cover that offers delivery port, described loam cake and the lower cover formation cavity that is connected, be provided with filter in the described cavity, it is characterized in that: the bottom of described lower cover is formed with axial evagination and connects with described delivery port in the position of the described delivery port of correspondence the first protruding neck, the bottom of described lower cover also is formed with the coaxial setting of the described first protruding neck and is sheathed on the second protruding neck outside this first protruding neck in the position of the described delivery port of correspondence, form between the described first protruding neck and the second protruding neck can and the suitable annular slot of water inlet connector of Washing Machine Panel.

As preferably, described filter comprises filtering frame and crosses filter ruffle that described filtration cover is set in described filtering frame outside.Cross filter ruffle and can adopt adsorptivity materials such as sponge, the current that play filtering through filter stand carry out once more the effect of filtration, purification.

As further preferred, the inner chamber of described loam cake is provided with internal thread, and the top of described lower cover is provided with external screw thread, is threaded between described loam cake and the lower cover, also is provided with sealing ring between described loam cake and the lower cover.Sealing ring can strengthen the sealing that loam cake is connected with lower cover, prevents to leak.

For convenience and being connected of water inlet pipe, as preferably, described loam cake is provided with axial evagination and connects with this water inlet in the position of described water inlet the 3rd protruding neck.

Be connected in order can better to match with Washing Machine Panel, as preferably, the bottom of described lower cover also is formed with a circle rib that extends vertically downwards along the edge, and the outer wall of this rib is provided with decorative pattern.Decorative pattern on the rib outer wall can increase gripping frictional force effectively, prevents slippage.

Compared with prior art, advantage of the present utility model is: the delivery port structure of having improved the filter lower cover, be provided with the protruding neck of two coaxial settings at the delivery port place, two with forming annular slot between the crown of roll neck, can block mutually with the water inlet connector of corresponding construction on the Washing Machine Panel and join, improve the compactness and the reliability that connect; Under the situation that does not need filter, filter can remove, water inlet pipe still can directly be inserted on the water inlet connector of Washing Machine Panel and use, and has improved the use flexibility of filter, and the user can select whether install filter according to the water quality condition of reality.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1～shown in Figure 4, washing machine inflow filter for the utility model embodiment, this filter includes loam cake 1 and the lower cover 2 that is connected together, loam cake 1 and lower cover 2 are connected with the formation cavity, be provided with filtering frame 3 in the cavity and cross filter ruffle 4, wherein, filtering frame 3 and to cross filter ruffle 4 all be prior art is crossed the outside that filter ruffle 4 adopts sorbing material such as sponges and is set in filtering frame 3;

Loam cake 1 top offers water inlet 11, the 3rd protruding neck 11 that is provided with axial evagination in the position of water inlet 111 and connects with this water inlet, and the inner chamber of loam cake 1 bottom is provided with internal thread 12;

Lower cover 2 offers delivery port 221, the top of lower cover 2 be provided with can and the external screw thread 21 that is threaded of the internal thread of loam cake realization, the bottom of lower cover 2 is formed with axial evagination and connects with delivery port in the position of corresponding delivery port 221 the first protruding neck 22, the bottom of lower cover 2 also is formed with the first protruding neck 22 coaxial settings and is sheathed on the second protruding neck 23 outside this first protruding neck 22 in the position of corresponding delivery port 221, form annular slot 24 between the first protruding neck 22 and the second protruding neck 23, the bottom of lower cover 2 also is formed with a circle rib 25 that extends vertically downwards along the edge, the outer wall of this rib 25 is provided with the decorative pattern that can effectively increase frictional force, between loam cake 1 and lower cover 2, also be provided with sealing ring 5, improve the sealing that is connected of loam cake 1 and lower cover 2.
