Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dehydrator in which a dehydrating liquid is provided in a dehydrating receiver, and more particularly to an improvement in the holding structure of a dehydrating receiver cover provided on the upper part of the dehydrating receiver.

Conventionally, in this type of dehydrator, a dewatering receiver cover having an inlet for approximately medium heat has been screwed and fixed to the flat part of the upper part of the dehydrating receiver.

However, as the number of parts increases and the cost increases,
Installation work was also troublesome.

For this purpose, one end of the dehydration receiver cover is attached so as to be openable and closable, and the other end is formed with a locking claw that projects downward, and a fitting groove corresponding to the locking claw is formed on the upper surface of the water receiver. However, there is a device in which the dehydration cover is attached by engaging a locking pawl in this fitting groove, but this structure prevents dimensional errors between the dehydration receiving cover and the inner box that forms the dehydration receiving tube. Due to variations in the amount of water, the engagement between the fitting groove and the locking pawl may not be successful, resulting in a decrease in holding force and the vibration of the dehydrating liquid causing the dehydration liquid to come off easily.

The present invention was devised in view of the above-mentioned drawbacks, and it is possible to reliably hold the dehydration receiving cover even if variations in dimensional errors occur without increasing the number of parts.

To explain one embodiment of the present invention shown in the figure below, 1 is the main body of a washing machine with a dehydrator, 2 is an inner box in which a washing tub 3 and a dehydrating tub 4 are integrally formed, and the bottom I of the washing tub 3 is A pulsator (not shown) is installed inside the dehydration receiver 4, and a large number of small holes 6 are provided on the peripheral wall.
A dehydrating liquid 5 having a dehydrating liquid 5 is disposed in the main body 1 and is rotated by washing and dehydrating motors (not shown) installed at the inner bottom of the main body 1.

8 is a flat part T at the top of the dehydration receiver 4 (a bag-shaped fitting groove formed continuously with the dehydration receiver 4 by a slide mold);
Reference numeral 9 denotes a positioning rib located on the side f of this bag-shaped fitting groove 8 and formed with an appropriate gap between it and a flange 10 formed on the periphery of the flat portion 7.

Reference numeral 11 denotes a dehydration receiving cover provided on the flat portion γ to close the upper opening of the dehydration receiving cylinder 4, and has an inlet 12 for putting the material to be dehydrated into and out of the substantially medium heat.

Note that this dehydration receiving cover 11 has its rear end connected to the inner box 2.
The rear upper part of the main body 1 is operated by inserting it between the lower end of the panel 15 and providing it with a structure such as a self-hinge so that it can be opened and closed freely.On the lower surface of the other end, there is a lock that protrudes downward corresponding to the fitting groove 8. The pawl 13 is formed with protrusions that fit between the rib 9 and the flange 10 at both front ends of the lateral sides of the pawl 13.

In the above configuration, after inserting one end of the dehydration receiving cover 11 between the operation panel 15 and the inner box 2 and attaching it so that it can be opened and closed with a self-hinge, the other end of the dehydration receiving cover 11 is folded down and the rib 9
At the same time, the protrusion 14 is fitted between the flange 10 and the flange 10, and the locking pawl 13 is engaged with the fitting groove 8, and the dehydration receiving cover 11 is attached to the dehydration receiving cylinder 4.
Attach to the flat part at the top.

Further, when it becomes necessary to open the dehydration receiving cover 11, the upper opening of the dehydration receiving cylinder 4 can be opened by simply pulling the dehydration receiving cover 11 upward.

As described above, in the present invention, a bag-shaped fitting groove is provided in the flat part of the upper part of the dehydration receiver, and a gap is provided on the side of the groove between the groove and the flange on the periphery of the flat part. While forming the ribs, the dewatering force tX? - Since the locking pawl that engages with the fitting groove and the protrusion that engages between the rib and the flange are formed respectively, the attachment position of the dehydration receiver cover is determined by the protrusion, and the inner box and the dehydration receiver are Even if the dimensional error of the cover varies, the fitting groove and locking claw will not shift.
The dehydration receiver cover can be held securely.

Furthermore, since the fitting groove is formed continuously with the dewatering receiver,
Even if water flows between the flat part and the dehydration receiver cover, it will flow into the dehydration receiver, and in winter, the collected water will not freeze and prevent the dehydration receiver cover from opening.

[Brief explanation of the drawing]

The drawings show an embodiment of the present invention; FIG. 1 is a partially cutaway sectional view of a washing machine with a dehydrator; FIG. 2 is a vertical sectional view of the main part as seen from the side of FIG. FIG. 3 is a perspective view of the main part of FIG. 1. In the figure, 4 is a dehydration receiver, 5 is a dewatering capacity, T is a flat part, 8 is a fitting groove, 9 is a rib, 10 is a flange, 11 is a dewatering receiver cover, 13 is a locking claw, and 14 is a protrusion. be.

Claims (1)

[Scope of utility model registration request] In this case, a dehydration receiver cover is disposed on the upper part of the dehydration receiver containing the dehydration liquid, and the flat part of the upper part of the dehydration receiver has a bag-shaped fitting groove that is continuous with the dehydration receiver, and a flat part. While forming ribs that form a gap between the peripheral flange and the flange,
The dewatering tray is characterized in that the dehydrating tray cover is formed with a locking pawl that engages with the fitting groove and a positioning protrusion that maintains the gap f between the rib and the flange.
