Problems solved by technology

[0007] 1. After the washing water of the washing machine in the prior art enters the filter cavity of the filter from the water inlet on one side, the water inlet on the other side is of a closed design, forming a closed filter cavity, and vortices are easily formed in the closed cavity, resulting in The lint is easy to flow out from the water inlet, which reduces the lint collection rate
[0008] 2. The water inlet of the filter in the prior art is easy to hang clothes

Embodiment approach

[0053] There is a certain distance between the box-type lint filter 200 and the bottom wall of the filter part 300 , and a water inlet 310 is formed between the bottom wall of the filter part 300 and the supporting frames on both sides of the box-type lint filter 200 .

[0054] In order to achieve a certain distance between the box-type lint filter 200 and the bottom wall of the filter part 300, there are boss structures at both ends of the filter part 300, and the box-type lint filter 200 is set Between the boss structures at both ends. The most common assembly method of the box-type lint filter 200 is clamping, that is, one end of the box-type lint filter 200 is provided with an elastic tongue, and the other end is provided with a claw. The insertion part used for inserting the claws of the box-type lint filter 200 is provided with a mounting part used to engage with the elastic tab of the lint filter 200 on the upper end protrusion structure of the filter part 300 .

Embodiment 1

[0065] Such as Figure 1-5 As shown, it is a box-type overflow filter device of the present invention, which includes an overflow part 100 and a filter part 300. The upper part of the bottom wall of the box-type overflow filter device is an overflow part 100, and the overflow part 100 is provided with some overflow holes. The overflow holes are used for When the washing water in the washing machine is higher than the limited water level, the excess washing water is discharged. The lower part of the bottom wall of the box-type overflow filter device is a filter part 300, and the two ends of the filter part 300 have boss structures respectively, and the box-type lint filter 200 is arranged between the boss structures at both ends. The most common way of assembling the box-type lint filter 200 and the filter part 300 is clamping, that is, one end of the box-type lint filter 200 is provided with an elastic tongue, and the other end is provided with a claw. Structurally, an insert...

Embodiment 2

[0076] Compared with Embodiment 1, the difference is only that: the filter part 300 is not provided with guide ribs 330, and the free end of the water guide baffle 340 is provided with a rotating shaft, which is inserted into the raised structures at both ends of the filter part to filter Corresponding limiting grooves are arranged on the protrusion structures at both ends of the upper part, and the rotation axis of the free end of the water guide baffle 340 moves along the track of the limiting groove to realize the swing at a fixed angle.

Abstract

The invention provides a box-type overflow filtering device. The box-type overflow filtering device comprises a filtering part; the filtering part is provided with a box-type line chipping filter; a filtering cavity is formed between the filtering part and the box-type line chipping filter; a water inlet is formed in each of two sides of the filtering cavity; a water guide baffle which is capable of swinging along a water inlet direction of the filtering cavity is connected into the filtering cavity; the box-type line chipping filter comprises a filtering front cover and a filtering rear cover which are connected; the filtering front cover is provided with a filtering screen; the filtering rear cover is provided with a water inlet of the filter and a chamber for collecting line chippings. According to the box-type line chipping filter having a brand-new structure, the water guide baffle is additionally arranged on the filtering part so as to well guide water to the box-type line chipping filter, and thus the collecting rate of the line chippings is greatly increased. The box-type overflow filtering device disclosed by the invention is simple in structure, low in production cost, good in filtering effect and worth being greatly promoted.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a box-type overflow filter device. Background technique [0002] Ordinary washing machines have a lint filter device. The lint filter of a double-tub washing machine is generally combined with an overflow filter to collect lint during washing and rinsing. Currently, there are three types of lint filters commonly used in wave-wheel washing machines on the market: Box fixed type, mesh bag swing type and mesh bag fixed type. Among them, the box-type fixed lint collection effect is poor. According to a machine with two lint filters, the lint collection rate of a washing program is about 60%; a swing-type lint filter has a program line The lint collection rate is about 50%, but the swinging lint filter is easy to hang clothes and fall off during the washing process; the net bag fixed lint filter has basically the same effect as the box-type fixed type, and the lint collection rate is ...
