Abstract

The utility model relates to a back water filtering device of the fully automatic wave wheel washing machine, which comprises a back water cover plate, a filter screen cover and a filter screen. The filter screen is formed by welding a filter screen bag and a filter screen frame, and an annular positioning frame is arranged at the upper end of the filter screen; an elastic U-shaped clipping bolt is arranged at the top end of the filter screen cover, a clipping claw is arranged at the lower end of the filter screen cover, the filter screen frame is inserted into a positioning rib on the filter screen cover through the annular positioning frame arranged at the upper end of the filter screen, the lower end of the filter screen frame is positioned through a knuckle, and the filter screen frame is connected with the filter screen cover; a groove is arranged on the back water cover plate, a back water outlet opening is arranged at the position corresponding to the filter screen frame, a clipping bolt opening is arranged at the upper end of the back water outlet opening, a clipping claw groove is arranged at the lower end of the back water outlet opening, the edge of the filter screen cover is embedded in the groove, the clipping claw arranged at the lower end of the filter screen cover is inserted into the clipping claw groove, and the elastic U-shaped clipping bolt arranged at the top end of the filter screen cover is embedded in the clipping tongue. Because the filter screen cover is adopted, the attrition of the filter screen bag is effectively prevented, to ensure that the filtering device can be installed at any position on the inner barrel wall of the washing machine, therefore the problem of the attrition of the screen bag of the screen bag type back water filtering device and the uncompromisable problem of the low water level washing and filtering effect are solved.

Description

The backwater filter of full-automatic impeller type washing machine

Technical field

The utility model relates to a kind of filter of washing machine, especially a kind of backwater filter of full-automatic impeller type washing machine.Belong to household electrical appliance technical field.

Background technology

Automatic washing machine filters the foreign material such as line bits that produce by the backwater filter in laundry processes, thereby guarantees to clean efficiently ratio.At present, the backwater filter mainly adopts mesh bag formula and two kinds of screen packs of chip.The filter that wherein adopts mesh bag formula screen pack is in washing process, mesh bag directly contacts with clothing, time one length can cause the mesh bag wearing and tearing, so generally it is installed in the top near steel ladle, the unconspicuous problem of filter effect in the time of still can causing low water level wash so again.

The utility model content

At having the problem that mesh bag formula backwater filter can not be taken into account the wearing and tearing and the low water level filter effect of clothing now, the purpose of this utility model is to provide a kind of novel full-automatic impeller type washing machine backwater filter, has solved the problem that wearing and tearing of mesh bag formula backwater filter mesh bag and low water level filter effect can not be taken into account.

For achieving the above object, the utility model is to realize by following technical scheme:

A kind of backwater filter of full-automatic impeller type washing machine is characterized in that comprising the backwater cover plate, filters square and screen pack; Described screen pack is made of at filtration rack inward flange the filtering mesh bag welding, in the upper end of filtering rack the circular orientation frame is arranged; Described screen pack has covered delivery port, its top is provided with elasticity u shape block tongue, the lower end is provided with claw, be provided with and filter the corresponding positioning rib of circular orientation frame on the rack at an upper portion thereof, be provided with hook in the left and right sides, the filtration rack inserts the positioning rib that screen pack covers by the circular orientation frame of upper end, and the lower end is located by hook, is connected with the filtration square; Have groove on the described backwater cover plate, top is put corresponding to the screen pack chord position and is had the backwater outlet, described backwater outlet exceeds the groove plane, backwater outlet upper end is provided with tongue port, the lower end is provided with the claw groove, filter square and be connected with the backwater cover plate by the edge being embedded in groove, lower end claw insertion claw groove, the upper end elasticity u shape block tongue embedding tongue port, the outward flange at the inward flange of filtration rack and the delivery port place of backwater cover plate closely cooperates.

The beneficial effects of the utility model are: the utility model is owing to adopted the filtration square, the wearing and tearing of filtering mesh bag have effectively been prevented, make filter can be installed in up and down any position of washing machine inner tub wall, finely solved the problem that the wearing and tearing of mesh bag formula backwater filter mesh bag and low water level wash filter effect can not be taken into account.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done concrete being described below:

Fig. 1 is a decomposing schematic representation of the present utility model; Fig. 2 is the cutaway view of screen pack; Fig. 3 is the installation diagram that filters square and screen pack; Fig. 4 is the front view of backwater cover plate; Fig. 5 is a work schematic diagram of the present utility model.

As shown in the figure, the utility model is made of backwater cover plate 1, screen pack 2 and filtration square 3.Wherein screen pack 2 is made up of on the inside casing that filters rack 4 filtering mesh bag 5 weldings; Screen pack 2 is installed in and filters square 3 back sides, and the positioning rib 7 of upper end, square 3 back sides is filtered in the circular orientation frame insertion of filtering rack 4 tops, and positions locking by the hook 9 that filters a series of rib 8 in square 3 back sides and filtration square 3 left and right sides.

Have groove 15 on the backwater cover plate 1, top has backwater outlet 14, backwater outlet 14 exceeds groove 15 planes, backwater exports 14 upper ends and is provided with tongue port 13, the lower end is provided with claw groove 16, the claw groove 16 that two claws 11 of filtration square 3 lower ends that will assemble with screen pack 2 insert on the backwater cover plates, the edge that filters square 3 embeds in the groove 15 of backwater cover plate, the elasticity u shape block tongue 6 that screen pack covers end embeds locking in the tongue port 13 of backwater cover plates upper end, and the inward flange that filters rack 4 and the backwater of backwater cover plate 1 export 14 outward flange and match.

During the utility model work, be installed on the washing machine inner tub wall, the backwater current that the agitation wheel for washing machine rotation produces are entered by backwater cover plate below, upwards by the delivery port on the backwater cover plate, enter filtering mesh bag, filtering mesh bag filters out the impurity in the water, and the water that has filtered covers delivery port 10 by screen pack and flows in the interior bucket, thereby plays the effect that backwater filters.During cleaning and filtrating equipment, push the elasticity u shape block tongue that screen pack covers, take off and filter square and screen pack, thereby the line of clearing up easily in the filtering mesh bag is considered impurity to be worth doing.
