Abstract

The utility model provides a thrum filter of a washing machine which can solve the problems that the connection part of the existing filter is easily loosened and difficultly screwed tightly. The utility model has the technical scheme that the thrum filter comprises a casing which comprises a water inlet pipe, a water outlet pipe and a mounting opening, wherein the casing is provided with a filter screen, a filter screen mounting frame, a sealing ring, a mounting frame supporter and a screwed cover. The utility model is characterized in that: the connecting structure between the screwed cover and the casing mounting opening is a screw connection. Because the screwed cover and the casing mounting opening employs the screw connection, with the entire circle screw connection, the cover is easily screwed and has the advantages of high reliability, long service life, easy compactness of the seal part and leakage prevention.

Description

The line bits filter of use in washing machine

Technical field

The utility model relates to the line bits filter of use in washing machine, specifically existing line is considered to be worth doing the improvement of filtration device structure.

Background technology

The line of washing machine bits filter is to be used for impurity such as line bits in the filtration washing water, to guarantee to have good clean result and higher clean ratio.Existing line bits filter normally is installed in the mesh bag formula structure in the washtub, it is fitted on the watercourse port on washtub water channel top, current are sent current into water channel by the rotary power that blade produced at the impeller back side, after entering the washings process mesh bag filtration in the water channel, filtered water stream is returned in the washtub, impurity such as line bits are then stayed in the bag, thereby reach the purpose of filtering the line bits.The setting height(from bottom) of mesh bag is based on a kind of like this consideration, because the mesh bag bag is suspended in the washtub, the clothing direct friction mesh bag that rotates in the washtub causes it to damage, thereby mesh bag is arranged on the higher position of water channel.But, the line bits filter that is installed in the washtub has the following disadvantages: 1, water level have only near or when reaching the mesh bag height, just have filtering function, when water level hangs down, a current seldom part can reach the mesh bag height or all then not reach the mesh bag height, and filter effect is had a greatly reduced quality.2, because the chance that the filtered water of outer barrel bottom is filtered is few, after use a period of time, make the line bits stop up draining valve or water pump, particularly the line bits stick on the water pump blade, cause water pump function to descend.In order to improve the quality that the outer barrel bottom filtered water is filtered, some washing machine manufacturer has designed bottom type line bits filter, and this filter is arranged in the discharge pipe line, after washings filter, flow through draining valve or water pump, thus significantly reduced the line bits amount that enters draining valve or water pump.But this filter still exists following deficiency: 1, first locking projection on the horn mouth of second locking projection of the locking lip in its structure and main body slidably mates, though adopt the locking projection dismounting comparatively quick and convenient, rotary distance is less than fixing once enclosing, but it only relies on the gradient of pair of locking projection to screw mutually, connection is a part, and mainly relies on the deformation characteristic of material itself.But, working of plastics Chang Erjiu it, easily aging distortion, or repeatedly after the dismounting, can make connecting portion loose, be difficult for screwing, may related sealing place water clock, thereby poor reliability, service life is short, and because first locking projection and whole housing on the horn mouth of main body are integral type, when connecting portion can not lock cause water clock after, can only change whole line and consider filter to be worth doing.Show fully that thus the bell-mouthed connected mode design of locking lip and main body is gone up and had obviously deficiency.2, screen pack adopts arc web plate formula, board-like net be upstream face to be filtering surface, be difficult for adhering to the line bits, and filter area is little.

How solving above-mentioned deficiency as early as possible, then is the design problem that the utility model faced.

Summary of the invention

The utility model provides a kind of line bits filter of use in washing machine, and it is easily loose that it can solve the connecting portion that existing filter exists, and problem such as is difficult for screwing.

In order to reach the purpose that solves the problems of the technologies described above, the technical solution of the utility model is, a kind of line bits filter of use in washing machine, it comprises shell, shell includes water inlet pipe, outlet pipe and installing port, screen pack, screen pack installing rack, sealing ring, installing rack supporter are housed in the shell, and screw lid, it is characterized in that: described lid and the syndeton of shell installing port of screwing is for being threaded.

In the utility model, also have following technical characterictic: the described connecting thread that screws lid and shell installing port is half-turn screw thread or whole circle screw thread.

In the utility model, also have following technical characterictic: described screen pack is the mesh bag formula.

The utility model compared with prior art has the following advantages and good effect: 1, screw lid and be threaded with the employing of shell installing port, rely on whole circle to be threaded, be easy to screw, use for a long time repeatedly, relaxation can not appear, and the reliability height, long service life, sealing place easily compresses, and weeping can not occur.2, screen pack adopts the mesh bag formula, and sack shape area is big, is easy to collect the line bits, and filter quality improves.

The specific embodiment

Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, line bits filter 7 of the present utility model is a bottom type, is installed in the drainage pipeline at the end in the outer barrel of washing machine.Shell 1 comprises water inlet pipe 1-1, outlet pipe 1-2, installing port 1-3.Screen pack 2 is installed on the screen pack installing rack 3, screen pack installing rack 3 is an integral type with installing rack supporter 5, sealing ring 4 is sleeved on the installing rack supporter 5, has on installing rack supporter 5 outer surfaces claw 5-1 is installed, and screws cover 6 and be connected by installation claw 5-1 with installing rack supporter 5.

Above-mentioned parts are enclosed in the cavity of shell 1, cover 6 screw thread 6-1 and are connected with the screw thread 1-3-1 of installing port 1-3 and screw by screwing.

Screw thread 6-1 and screw thread 1-3-1 enclose screw thread mostly, so during fabrication, help the demoulding.Certainly, also can make whole circle screw thread.

Washings enter from water inlet pipe 1-1 in the chamber of shell 1, filter the back through filter screen 2 and drain into draining valve or water pump from outlet pipe 1-2, thereby reach the purpose of bottom wash water filtration line bits.

When need cleaning line bits, rotating handles 6-2 makes and screws lid and installing port disengaging, takes off mesh bag formula screen pack 2, after cleaning out, is reinstalled.

Certainly, the utility model is not limited to above-mentioned example, and in essence creation scope of the present utility model, the utility model also has many variations, transforms, and adds or replacement, also all belongs to protection domain of the present utility model.
