Description

DETAILED DESCRIPTION OF THE INVENTION The present invention connects the locking device for fixing the inner frame to the operating section at the front of the inner frame using a simple means such as a wire, and also provides an adjustment device between the locking device and the operating section. The purpose of the present invention is to provide a drawer-type washing machine which is provided at low cost and allows the inner frame to be opened and closed reliably.

Although there is no conventional washing machine on the market that is suitable to be exemplified as a conventional example of the present invention, there has been a demand for a pull-out type washing machine due to specific housing circumstances.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In the figure, reference numeral 1 denotes an outer frame, and the front surface has an opening 2 on almost the entire surface. 3 is the inner frame. This inner frame 3 is provided at the bottom of the outer frame 1 via a hinge 4 provided below the inner frame 3 so that it can be rotated in and out of the outer frame 1 through the opening 2. Reference numeral 5 denotes a dehydration rack that has a washing and dehydration tank (not shown) inside, and a support plate 6 is installed in the center of the outer bottom to control the rotation of the motor 7 to the washing and dehydration tank and the inner bottom of the washing and dehydration tank. A mechanical case 8 is provided which includes a mechanism (not shown) for transmitting information to a pulsator (not shown) provided in the pulsator. Reference numeral 9 denotes an elastic mechanism provided between the support plate 6 and the hanging frame 10 protruding from the inner frame 3 toward the outer frame 1 side, and elastically supports the dewatering uke 5. 11 is a cover provided on the upper part of the hanging frame 10, and has an input port 12 at the center and a water supply port 1 at the rear.
It has 3. 14 is a water supply valve provided at the upper rear surface of the outer frame 1, one end of which is connected to the water supply port 13 via a water supply hose 15, and the other end connected to a pressure hose 16.
It is connected to a water outlet (not shown) via.
Numerals 17 and 18 are latches provided on the inner wall of the outer frame 1, and are adapted to engage with hooks 19 at predetermined positions when the inner frame 3 is opened and stored, respectively. This hook 19 is rotatably supported by a shaft 21 on a side part 20 of the hanging frame 10 on the side of the outer frame 1, and a tight spring 22 provided between the side part 20 and the hook 19 keeps the hook 17, 18, and is prevented from rotating beyond the position where it engages with latches 17 and 18 by abutment 23. 24
25 is a spacer provided between the side portion 20 and the hook 19, and 25 is a stopper provided on the hook 19, consisting of a rectangular portion and a cylindrical portion. It has a notch 41 consisting of a circular portion and a groove portion having a width smaller than the inner diameter. 26 is a stopper A provided at the rear of the hanging frame 10, and 27 is a stopper B provided on the inner wall of the outer frame 1 so as to come into contact with the stopper A26 at a predetermined position when the inner frame 3 is closed. 28 is a stopper C provided on the side portion 20 at the rear of the hanging frame 10;
A stopper D 29 is provided on the inner wall of the outer frame 1 so as to come into contact with the stopper C28 at a predetermined position when the inner frame 3 is opened. Reference numeral 30 denotes a handle with a substantially L-shaped cross section provided on the front surface of the inner frame 3, and inside it,
A lever 32 is rotatably supported by a shaft 31. At the center of the upper part of the lever 32, there is a notch 33 having a substantially flask shape and consisting of a circular part and a groove having a width smaller than the diameter of the circular part. 34 is a wire, a retaining ring 35 is engaged at both ends, and the wire is provided between the retaining fitting 25 and the lever 32 via bushes A36 and 37. This bush A36,3
7 is a round hole 3 larger than the diameter of the wire 34 inside.
8 and a collar 40 having a diameter larger than the diameter of the cylinder 39 at one end. Further, the diameter of the cylinder 39 is made slightly smaller than the circular portions of the flask-shaped notch 41 and the notch 33 of the lever 32. In addition, within the handle 30, the inner frame 3 near the notch 33 of the lever 32 has bushes A36 and 37 of the same shape.
A bush B42 is provided which has two internal circular holes. In addition, a total of 3
A bushing C43 is provided on the hanging frame 10. Inside this bushing C43 is bushing B4.
2 and holes 44 and 45 of the same size are provided, and a groove 57 having a width wider than the wire 34 is provided along all sides of part of the large hole 44 and small hole 45. This large hole 44 is set to be slightly larger than the diameter of the flexible tube 46, and the small hole 45 is set to be sufficiently larger than the wire 34. The flexible tube 46 is elastically provided in each of the large holes 44 between the bushes B and C and between the bushes C, and has a hole 47 through which the wire 34 can smoothly slide. 48 is a wire tension fitting provided between the bushes C at a position where the flexible tube 46 is not provided. This wire-strapped metal fitting 48 is made up of a substantially rectangular body portion 50 of a cylindrical portion 49 which is curved.
9, it is rotatably supported by the lower part of the adjustment screw 51. A screw guide 52 has a screw portion in the center and supports the adjustment screw 51 on the hanging frame 10. 53 is a lock nut for fixing the adjustment screw 51. 54 is a control timer, and 55 is a leg.

Next, the mounting structure around the wire 34 will be explained. As shown in Fig. 7, the completed wire 56 includes a flexible tube 46 and bushes A36 and 37.
and bush B42 as shown in the figure.
4, and both ends are secured by retaining rings 35. Here, the flexible tube 46, bush B42, and bushes A36, 37 have internal holes larger than the diameter of the wire 34, so the wire 34
The parts can be slid freely. When attaching this completed wire 56 to the lever 32, stopper 25, and bush C43, each notch 33, 4
1. First, the wire 34 is passed through the groove 57, and then the bushes A 36, 37 and the flexible tube 46 are inserted in sequence. Further, the wire 34 is applied to the body 50 of the wire tensioning fitting 48 and the wire 34 is lowered using the adjustment screw 51 to eliminate slack.

Next, the operation will be explained. When opening the inner frame 3, when the lever 32 in the handle 30 is rotated toward you, the hook 19 is rotated via the wire 34 and the stopper 25, and the latch 18 is released from the hook 19, and the inner frame 3 is opened. is rotatable. In this state, handle 3
When the lever 32 is released when the stopper C28 comes into contact with the stopper D29, the hook 19 engages with the latch 17 by the lock spring 22, and the lever 32 also returns to its original state. Further, when closing the inner frame 3, the same procedure may be performed.

As explained above, according to the present invention, even if the lock device and the lever are not located in a straight line, the wire can slide smoothly by the flexible tube, and the wire tension can be adjusted by the device. To provide a drawer type washing machine which can be easily, accurately and reliably carried out, has simple structure and assembly, can surely operate and lock an inner frame, and is inexpensive.
