Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a washing machine that can gently wash perishable clothing such as knitwear without opening the washing machine.

Conventional Structure and Problems Conventionally, when washing knitted items, etc., a washing adapter/throat has been used, and a dehydrating and dehydrating washing machine using this adapter net will be described below.

In Figure 1, 1 is the housing of the washing machine, 2 is a through hole 3 in the peripheral wall.
This is an inner tank in which washing, rinsing, and dehydration are carried out, and a balancer 4 is disposed at the upper opening and a pulsator 6° is disposed at the center of the inner bottom.

6 is an outer tank rotatably housing the inner tank 2, 7 is a pulsator shaft, and the pulsator 6 is attached to the upper end. 8 is a dewatering shaft fixed to the inner tank 2 and arranged concentrically with the pulsator shaft 7, 9 is a gear case in which a reduction gear for the pulsator shaft 7 is housed, and 1o is a pulley. The pulsator shaft 7 is connected to a pulley 10 via a gear case 9 and a spring clutch for switching between the pulsator shaft 7 and the dewatering shaft 8. Reference numeral 11 denotes a motor, whose rotation is transmitted to the pulsator shaft 7 or the dewatering shaft 8 via a motor pulley 12 and a belt 13.

Reference numeral 14 denotes a vibration isolator that suspends and holds the vibration system of the outer tank 6 and the motor 11 from the upper four corners of the housing 1. 15 is a drainage port provided at the bottom of the outer tank 6, and electromagnetic pulp 16. It is connected via a hose 17 to a drain port 18 provided in a portion of the housing 1 . 19 is a leg.

The configuration of the adapter net 20 used in the washing machine having the above configuration was as shown in FIGS. 2 to 7.

Both ends of the semicircular frame member 21 are connected to pins 2 via joints 22.
3K joints are rotatably connected to form a frame 24, and this joint 22 has an inverted cross-section, and by forming an abutment part 26 in the upper bent part, it can be rotated in the E direction in FIG. Although the frame member 21 rotates, the frame member 21 is configured to rotate only slightly in the direction parallel to the frame member 21.

Therefore, if the net 26 is fixed to the edge of the frame 24 opposite to where the contact portion 25 is located, then the adapter net 2o is bent in the direction of the arrow E, as shown in FIGS. 5 and 6. Although no unreasonable tensile force is applied to the mesh body 26 in the configuration shown in FIG. 2, the bending of the mesh body 26 in the direction opposite to the direction of the arrow E in which the mesh body 26 is subjected to the tensile force is prevented by the abutting portions 26. Ru.

To attach the adapter net 20 to the inner tank 2, the fifth
Place the adapter net 20 into the inner tank 2 by rotating it slightly in the direction of arrow E as shown in the figure or completely rotating it as shown in Figure 6, and then insert the adapter net 20 in the opposite direction to the direction of arrow E. The engaging protrusion 2 that can be opened in the direction and retracted is connected to the dewatering hole 3.
If the adapter net 2o is inserted into the inner tank 2, the adapter net 2o is attached to the inner tank 2.
Further, the sheathed butane nod 20 can be removed by performing the operation opposite to the above.

When washing, attach the adapter net 20 above the pulsator 5 and below the water surface, and when the laundry is placed on the adapter net 20 and the pulsator 6 is rotated, the water flow from the pulsator 5 is pulsator 5
Adapter net 2
A force in the direction of the pulsator 6 is also applied to the pulsator 6.

However, even if this force is applied, since the joint 22 is provided with the contact portion 2S, the adapter net 2o will not bend and come off from the inner tub 2 during washing. When attaching it to the tank 2, the positional relationship between the dewatering hole 3 and the engaging protrusion 27 was not determined, and it was necessary to search for the dehydrating hole 3 by hand, which was very troublesome.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and enables the adapter net to be easily attached to the inner tank.

Structure of the Invention The washing machine of the present invention includes a recessed portion provided at the inner peripheral edge of the bottom of the washing tub;
The adapter net has a retaining protrusion that fits into the dewatering hole of the washing tub, and by forming a protrusion that is inserted into the recess, the adapter net can be positioned easily when attached to the washing tub. It's easy, and it's two things.

DESCRIPTION OF THE EMBODIMENT FIG. 9 shows the adapter net 28 in the embodiment,
A projection 3o is provided at the end 5 of the frame member 29, and this projection 30 is loosely fitted into the through hole 32 of the joint 31 to form a frame body,
In addition, a net 33 is attached to the lower edge of the frame member 29 to form an adapter net 28. A cylinder 34 is planted on the central surface of the frame member 29, and a locking piece 35 is provided on the back surface. .

An engaging protrusion 36 is attached to the cylindrical body 34, and the locking protrusion 36 is loosely fitted into the cylindrical body 34.
The pin 37 is longer than 4, and the l/no<-38 is fixed to the end of the pin 37 and locked to the locking piece 35.

A protrusion 39 is provided at the lower end of the frame member 29, and this protrusion 3
9 and the cylinder 34 is formed by the center of the recess 41 formed between the dehydration hole 3 in the inner tank 2 and the convex part 40 provided on the inner peripheral edge of the bottom of the inner tank 2. When the adapter net 28 is put into the inner tank 2 with the protrusion 39 of the adapter net 28, which is made equal to the angle θ', fitted into the recess 41 formed on the inner peripheral edge of the bottom of the inner tank 2, the above-mentioned center Due to the angle θ=θ', the cylinder 34 faces the dewatering hole 3. Then, when the pin 37 of the engagement protrusion 36 is inserted into the cylinder 34, the tip of this pin 37 fits into the dehydrating hole 3, and the lever 38
When the adapter net 28 is locked to the locking piece 35, the adapter net 28 is fixed to the inner tank 2 via the engagement protrusion 36.

Next, when removing the adapter net 28 from the inner tank 2,
The lever 38 and the locking piece 35 may be locked once again, and the engaging protrusion 36 may be pulled out from the cylindrical body 34.

Note that if the net body 33 and the frame member 29 are integrally molded from resin, good ocular productivity will be achieved.

Effects of the Invention As described above, the washing machine of the present invention is equipped with an adapter net that makes it extremely easy to attach and detach the washing tub, making it easy to handle.
