BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine in which a washing liquid in a water receiving tank is circulated for washing and rinsing.

[Detailed Description of the Invention]

[0003]

2. Description of the Related Art Conventionally, a washing machine of this type is shown in FIGS.
The structure shown in FIG. The configuration will be described below.

As shown in FIG. 5, the washing / dehydrating tub 1 has a substantially cylindrical shape, and a pulsator 2 is rotatably arranged at the center bottom. A circulating water channel cover 4 forming a circulating water channel 3 is attached to the inner wall of the washing / dehydrating tub 1, and a substantially annular balancer 6 forming a discharge port 5 together with the circulating water channel cover 4 is attached to the upper portion of the washing / dewatering. It is fixed to the water tank 1 by welding. The pulsator 2 has a back blade 7 on the lower surface.

The water receiving tub 8 contains the washing / dehydrating tub 1, an upper cover 9 is provided on the upper part so as to cover the balancer 6, and a substrate 10 is mounted on the outer bottom part. Motor 1 on board 10
1, the drive mechanism unit 12, the drain valve 13, etc.
The outer edge portion of 0 is supported by being suspended from the upper corner of the outer frame 16 via the vibration isolator 14 and the suspension rod 15. The drain 17 is
It is provided at the bottom of the water receiving tank 8 and communicates with the outside of the machine by a drain hose 18 via a drain valve 13.

The circulating water channel cover 4 is, as shown in FIG.
Protrusions 19 and claws 20 are provided in the lower and central portions, respectively, and a washing and dehydrating tub 1 is provided with a recess 21 and a claw hooking groove 22, respectively. I'm wearing it. A fitting claw 23 is provided on the upper end of the circulating water channel cover 4, and the fitting claw 23 is inserted into a recess (not shown) provided in the balancer 6.

The operation of the above structure will be described. In the washing or rinsing process, after the clothes and the detergent are put into the washing and dehydrating tub 1, when the operation is started, the motor 11 is automatically rotated after the water is supplied to a predetermined water level. The pulsator 2 is rotationally driven by the rotational force of the motor 11 via the drive mechanism section 12 to stir the clothes. Here, as the pulsator 2 rotates, the back blade 7 provided on the lower surface of the pulsator 2 sucks up the washing liquid in the lower part of the water receiving tank 8, discharges it through the circulation water passage 3 and discharges it from the discharge port 5, and drops it again on the water surface. This promotes dissolution of the detergent while circulating the washing liquid.

On the other hand, in the dehydration process, the clutch built in the drive mechanism section 12 is switched in association with the opening / closing operation of the drain valve 13, and the washing / dehydrating tub 1 is driven by the rotational force of the motor 11 via the drive mechanism section 12. Drive to rotate. Therefore, the clothes in the washing / dehydrating tub 1 are pressed against the inner peripheral surface of the washing / dewatering tub 1 by the centrifugal force due to the rotation, and the clothes are dehydrated. The dewatering liquid moves from the washing / dehydrating tub 1 to the water receiving tub 8 through a hole (not shown) provided in the washing / dehydrating tub 1, and the water receiving tub 8
Drain hose 1 from lower drain port 17 via drain valve 13
It passes through 8 and is discharged out of the plane.

[0009]

With such a conventional structure, when the circulating water channel cover 4 is to be removed, the balancer 6 must be removed from the washing / dehydrating tub 1, and when the balancer 6 is removed, Washing and dehydration tank 1
Since the welded portion of the balancer 6 must be cut, there is a problem that the circulation water channel cover 4 cannot be removed.

Further, when the balancer 6 and the washing / dehydrating tank 1 are attached by screwing, there is a problem of increased cost.

The present invention solves the above-mentioned conventional problems, and an object thereof is to improve the workability of removing the circulating water channel cover.

[0012]

In order to achieve the above-mentioned object, the present invention has a washing and dehydrating tub in which a pulsator is rotatably disposed at a central bottom portion, and a water receiving tub which contains the washing and dehydrating tub. The washing / dehydrating tub is provided with a washing / dehydrating tub and a circulating water channel cover, and a circulating water channel for forcibly circulating the water in the water receiving tub and discharging the water from the upper portion of the washing / dehydrating tank is provided. , A first engaging portion for fixing is provided on an upper portion, and a second engaging portion engageable with the first engaging portion is formed on an upper portion of the circulating water channel cover mounting portion of the washing / dehydrating tub. The opening is provided so as to communicate with the first engaging portion or the second engaging portion.

[0013]

According to the present invention, when the circulating water channel cover is to be removed from the washing / dehydrating tank by the above-mentioned means for solving the problem, a tool is inserted into the opening communicating with the first engaging portion or the second engaging portion. By inserting and pulling out, the circulating water channel cover can be easily removed.

[0014]
