Description

[Detailed description of the invention] This invention consists of installing a bag-shaped lint filter with an open top almost horizontally above the washing water level on the inner wall of the washing tub, and directing the liquid in the washing tub toward the opening on the top of the lint filter. This is a system that uses a lint filter to capture the thread waste contained in the liquid by feeding water, and is capable of capturing a large amount of thread waste.

This will be explained below based on the drawings.

Reference numeral 1 denotes an outer tank, in which a dewatering/washing tank 3 having a large number of small holes 2 for dehydrating is housed.

A rotor blade 6 attached to a rotor blade shaft 5 is disposed in an opening 4 provided at the center of the bottom of the washing tub 3, and a plurality of back blades 7 are formed on the back surface of the rotor blade 6. ing.

As is clear from FIG. 2, on the outer bottom surface of the washing tub 3, an annular rib 8 with a portion 8' open and a plurality of bosses 9 are vertically provided.

Reference numeral 10 denotes a washing tub board fixed to the drive shaft 11 of the washing tub 3. The annular rib 8 and boss 9 are in contact with the board 11, and screws 12 are tightened to the boss 9 to connect the board 10 and the washing tub 3. are combined.

A pump chamber 13 is formed on the back side of the rotary blade 6 by the substrate 10 and the annular rib 8.

A plurality of through holes 14 are provided in the substrate 10, and when the rotary blade 60 rotates, the liquid between the outer tub 1 and the washing tub 3 flows through the through holes 14 as shown by the arrow in FIG. 1 due to the pump action of the back blade 7. Pump room 13
be sucked into.

15 is a bearing case, 16 is a motor, and these are attached to the machine frame (
(not shown) is attached to the bottom of an outer tank 1 suspended in a vibration-proof manner.

The outer bottom surface of the washing tub 3 has an open part 8 of the annular rib 8.
A discharge port 17 of a pump chamber 13 connected to the pump chamber 1 is formed.

Reference numeral 18 denotes a cover attached to a part of the corner of the outer bottom surface of the washing tub in order to form the discharge port 17.

Numeral 19 is a screw for attaching the upper end flange 20 of the cover 18 to the washing tub 3.

A vertical groove 21 whose lower end communicates with the discharge port 17 is formed in the inner wall of the washing tub 3, and a water pipe 22 made by blow molding is fitted into the vertical groove 21.

The lower end of this water pipe 22 is connected to the discharge port 17, while the upper end is curved downward and placed in a recess 24 formed in the inner circumferential wall of the balance ring 23.

32 is a liquid that acts as a balancer.

A bag-shaped lint filter 2 whose upper surface is open facing the tip of the water pipe 22 is disposed on the inner peripheral wall of the balance ring 23.
5 is installed.

26 is a mounting stand for the lint filter 25.

A frame 27 that shapes the upper opening of this lint filter 25
consists of an upper frame 28, a lower frame 29, etc., and holds the edge of a fine bag-like net 30 between the two frames 27,28.

A hanging piece 31 is integrally formed on the side of the lower frame 29 opposite to the inner wall of the washing tub.

Therefore, during washing or rinsing, the liquid between the outer tub 1 and the washing tub 3, which is sucked into the pump chamber 13 by the pumping action of the back blade 7, passes through the discharge port 17 and the water pipe 22 and flows into the lint as shown by the arrow in FIG. The water is sent to the filter 25, and the lint contained in the liquid is captured by the lint filter 25.

Since the lint filter 25 is disposed above the washing water level, the lint once captured can be reliably stored without escaping due to the water flow.

By the way, in the conventional lint filter, a hanging piece was not formed on the frame body 27 as shown in FIG.

In such a case, if the load is large and the water level is high, the net 30 will be pushed sideways and flattened by the water flow and load F, as shown in Figure 4, and as a result, the net 30 will become clogged early. It was difficult to capture a large amount of thread waste.

In addition, the net 30 may get caught between the loads and the frame 27 may come off.

However, according to the present invention, since the hanging piece 31 is formed on the frame 27, when the load is large and the water level is high,
As shown in FIG. 3, the net 30 is pushed up by the water flow or load, and its tip becomes a balloon-shaped part made of a thin film of water, and thread waste is stored one after another in this balloon-shaped part.

Therefore, a large amount of thread waste can be captured.

Moreover, the balloon-shaped net 30 floats up due to the buoyancy, and is less likely to be caught between loads, thereby providing excellent effects such as making it difficult for the frame 27 to come off.

In the above embodiment, the liquid in the washing tub is fed to the lint filter 25 by the pump action of the back blade 7 of the rotary blade, but other means such as a separate water pump may be used.

Furthermore, although the washing tub is designed to serve as a dehydration tub, it can of course also be applied to a simple washing tub.
