Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a washing machine equipped with a lint filter device using a lower injection channel.

(B) Prior Art As shown in FIG. 6, an injection channel 62 to the lower part of a washing tub 61 is recessed in the tub, and its front opening is closed with a separate plate-shaped cover 63 having a water inlet. . The cover 63 is fixed to the injection channel 62 with claws or the like 64, and forms part of the inner surface of the tank. Lint filter device 6
5 is removably fixed in a shape that protrudes from the front surface of this cover 63, and is submerged in water during washing, and a rotating water stream is introduced from the water inlets 65, 65 and discharged from the water outlet 67 where the net 66 is located. A net 66 is used to remove lint and the like. 68 is a plate-shaped guide plate that directs the rotating water flow toward the water outlet 67.

When the rotating water stream is thus introduced and discharged to remove lint and the like, the laundry carried by the water stream collides with the lint filter device 65. Then, the cover 63 is pushed outward by this force, and a gap is momentarily created between the cover 63 and the rim 69 of the water injection channel opening of the tank. Therefore, thin laundry items, such as socks and handkerchiefs, sometimes got caught in these gaps.

(c) Purpose of the invention The purpose of the invention is to prevent laundry from getting caught by making it difficult to create the above-mentioned gaps.

(d) Structure of the invention In this invention, a water inlet and a water outlet are formed on the cover, a lint filter made of net is attached to the front of the water outlet, a guide body is integrally formed on the cover, and the guide body is attached to the cover. It extends rearward and almost touches the inner surface of the water injection channel. Therefore, even if external pressure is applied to the cover, the inner surface of the injection channel supports this force via the guide body, so the cover does not bend, and therefore a gap is less likely to form between the cover and the periphery of the opening.

(E) Embodiment To explain based on FIGS. 1 to 5, 1 is a two-tub washing machine in which a washing tub 2 and a dewatering tank (not shown) are arranged side by side in the machine body. A pulsator 3 that generates a reverse water flow is disposed at the inner bottom of the tank. 4 is an upper water filling box for normal water filling.

Reference numeral 5 denotes a water inlet passage leading to the lower part, which is formed as a vertical recess in the left rear corner of the washing tub 2, and is closed by fitting a plate-shaped cover 6 around the periphery of the opening. This cover 6 has a mountain-shaped protrusion 7 protruding from the middle to the upper part to prevent water from splashing out, and this protrusion 7 sharply narrows the area below the middle part to form a lower water inlet 8... at the lowermost part. A bulge 9 is integrally formed forward slightly above this water inlet 8.... A water outlet 10 is formed in front of this bulge, and water inlets 11... are formed on both sides of the bulge 9 on both sides of the water outlet 10.

Reference numeral 12 denotes a guide body integrally formed on the inner surface of the bulging portion 9, which includes a vertically elongated mountain-shaped water guide plate 13 with its top facing the water outlet 10, and a guide body 12 extending from the middle of the water guide plate 13 until it passes through the water outlet 10. A protruding horizontal wide rectifying plate 14 and a pair of vertically long rectifying plates extending rearward from both ends corresponding to the hem of the water guide plate 13 and abutting the inner surface of the water injection channel 5 or close to it with a design error. It consists of plate-shaped partition plates 15, 15. 16 is water guide plate 1
This is a partition piece that protrudes from the top of 3. here,
The water guide plate 13 and the partition plates 15, 15 allow the introduced reversed water flow to be smoothly discharged to the water outlet 10. The rectifying plate 14 serves not only to rectify the water flow but also to constantly expand a net, which will be described later. The partition plates 15, 15 form a partition area 17 at a portion corresponding to the bulge 9, and secure the water injection channel 5. That is, it prevents the reversed water flow from entering the partitioned area and prevents the lower water injection performance from deteriorating due to the attachment of lint and the like. Also, partition plates 15, 15
When the cover 6 receives external pressure from the front, the injection channel 5
It supports the cover 6 in cooperation with the inner surface, suppresses deflection of the cover 6, and reduces the gap between the cover 6 and the periphery of the injection channel opening as much as possible. The partition piece 16 is the water inlet 11 where the water flow is reversed...
Prevent it from slipping away.

18 is a square frame-shaped lint filter with a net 19 fixed by a holding frame 20, and is removably attached to the upper and lower edges of the water outlet 10 by elastic engaging claws 21 and locking pieces 22. be. Therefore, the net 19 is located in front of the water outlet 10, and the current plate 14
It is constantly being expanded by.

To explain the operation, first, water is poured into the washing tub 2 according to the amount of clothes, detergent is added as necessary, and the pulsator 3 is turned over. Then, a rotating water flow is generated in the washing tub 2 that becomes higher on the circumferential side, and the lint filter 18 is constantly submerged in water. The reversed water flow enters from the water inlet 11..., the water guide plate 13, and the partition plate 1.
5, 15 and the front water outlet 1 along the partition piece 16
0 and exits through net 19. During this time, the net 19 collects so-called lint such as lint in the water. The collected lint is discarded by removing the lint filter 18.

When water is injected into the lower part, water is supplied into the injection channel 5 from above. The water is deflected rearward at the middle part by the constriction on the inner surface of the chevron-shaped protrusion 7, collides with the guide body 12, and reaches the lower part without being disturbed. In particular, at the rear of the bulging part 9, it mainly passes through the divided area 17 and reaches the water inlet 8 at the bottom without being disturbed by lint etc.
From there it is fed into the tank. Therefore, the performance of lower water injection does not deteriorate significantly, and effects such as suppressing foaming during rinsing are brought about.

(F) Effects of the invention The present invention can protect the cover of the water injection channel from bending due to external pressure, reduce the amount of laundry caught around the opening of the water injection channel, and provide a washing machine that is easy to use.
