The lid 5 is arranged in the center of the outer box 2 so as to be openable and closable.

The water receiver 6 has a cylindrical shape to receive washing water. A dewatering hole 8 is provided on the outer periphery of the dehydrating tub/washing tub (inner tub) 7. The rotary blade 9 is arranged at the center bottom of the dehydration tub/washing tub 7 to agitate the laundry. A rotational force is obtained by an electric motor (motor) 1o, and a motor pulley 11. Via the V-belt 12, the information is transmitted to a mechanical case 13 containing a clutch mechanism, which rotates the rotary blades 9 during washing, and rotates the spin-drying tub/washing tub 7 during spin-drying. The electric motor 10° mechanical case 13 is attached to a reinforcing plate 14.

The entire mechanism is suspended by a vibration isolator 15. Spherical receivers 16 are provided at the four corners of the reinforcing plate 14, and the vibration isolator 15 is connected to the spherical receivers 16 via rods 17.
It is slidably attached to the top of the. Reference numeral 18 denotes adjustment legs provided at the four corners of the bottom of the outer frame, which are used to adjust so that there is no wobbling when installed on the floor, and these devices are usually provided at one or two locations. 19 is a leg. A drain valve is installed inside the drain cock 20 so as to be opened and closed, and when the washing water in the water receiver 6 is to be drained, it is opened and discharged to the outside of the machine. The operation of the drain cock 20 is usually done using an electromagnetic magnet 2.
It opens and closes with one force. A drain hose 22 connecting the drain cock 20 and the outside of the machine drains the washing water. 23 is a balancer ring that seals liquid inside, and when the laundry in the dehydration tub/washing tub T is unevenly dehydrated, the balancer ring is installed so that the liquid is balanced according to the unevenness of the laundry. Move within 23. Reference numeral 24 denotes a dewatering tray cover that reinforces the upper opening of the water tray 6. In the conventional dehydration process, the dehydration hole 8 was used to disperse water into a water receiver using centrifugal force. In addition, when the dewatering hole 8 was eliminated, the inner tank would be continuously rotated from the upper part of the inner tank, and all the washing liquid would be scattered and drained by the centrifugal force.

FIG. 6 is an installation diagram of the safety switch 26 provided in a conventional single-tub centrifugal dehydrating washing machine. 26 hangs down, and the lever 26 is designed to open the contact inside the safety switch 26 via the lever and stop the rotation of the water drainer, just before the water receiver shakes horizontally during spin-drying and violently hits the inner surface of the main body. Stop the electric motor. The safety switch 26 is equipped with a waterproof cover 27 and is fastened together with a screw 29 to a mounting boss 28 hanging down from the outer box 2. An arm 30 interlocking with a lid is provided in front of the safety switch 25, and when the lid 5 is opened, a switch 1 inside the safety switch 25 is turned OFF via this arm 30i.

Therefore, if the lid 5 is opened while the dehydration tank is rotating, the dehydration tank (inner tank) will stop.

Problems to be Solved by the Invention In such a conventional configuration, it is necessary to provide a mounting post 28 on the top surface of the outer box 2 in order to mount the safety switch 25, and when integrally molded with resin etc. There was always a sink mark on the top surface (Fig. 5, the two-part border indicated by the arrows), which had a lower appearance value. Also, inside the panel 3 was a day-shaped storage with an opening at the bottom. Since it is a box, steam from washing water or hot water can directly enter the box and cause rust on electrical components, so the safety switch 25 requires a cover or the like.Furthermore, the safety switch 25 needs a cover, etc. However, when pressing the top surface of the panel chamber 3 with your hand or placing a heavy object on top of the outer box, the outer box deforms and the top surface of the outer box directly touches the outer box. This deformation causes the attached safety switch 25 to flex, causing the problem that the safety switch cannot operate normally.

In view of the above-mentioned problems, the present invention provides a single-tub centrifugal dehydrating washing machine that does not cause sink marks on the top surface of the panel and allows a safety switch to operate normally.

Means for Solving the Problems In order to solve these problems, the single-tub centrifugal dehydrating washing machine of the present invention has a box body with a panel chamber opening formed on the rear surface, and is equipped with a safety switch mounting boss. With this configuration, the safety switch can be installed on the bottom of the box that opens to the rear, and as a result, the aesthetic appearance of the installation and the prevention of water leakage from the opening are reduced. It is possible to prevent rust caused by intrusion and improve the accuracy of safety switches.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to FIGS. 1 to 3. In the figure, a bottom surface 40 is provided inside the outer box 2 integrally with the outer box 2, a stepped portion 41 is locally provided on the bottom surface 40, and a mounting hole is formed in the vertical direction of the mounting boss 42 in the stepped portion 41. It is set up in Further, a mounting hole 43 is provided in the bottom surface 4o so as to be in contact with the mounting boss, and the safety switch 25 is mounted thereon and attached using a mounting screw 44. Therefore, the safety switch 26 is partitioned at the bottom surface 40 so that the main body is located on the panel chamber 45 side from the mounting hole. If the mounting hole 43 has substantially the same shape as the main body of the safety switch 25, it can be made into a waterproof wall that can cope with the scattering of steam and water.

FIG. 2 is a perspective view of the installation of the bottom surface 40, the mounting boss 42, and the safety switch 25. By forming the stepped portion 41 provided on the bottom surface 40, the mounting boss 42 can be placed at the center of the bottom surface. The mounting hole 43 can also be formed in the bottom surface so as to be close to the mounting boss 42 in the center of the bottom surface, so that the safety switch 25 can be placed at any position on the bottom surface.

The panel chamber 45 provided in the upper box is made of a resin mold and is slid in the direction of arrow A as shown in FIG. 3 in order to have a backward sliding mold structure. The upper box surface is formed by sliding in the direction of the arrow, and the mounting hole is formed by sliding the mold in the convex direction. The stepped portion 41 is formed by a mold, the mounting boss 42 is formed by a mold and a mold B, and the screw mounting hole 46 is provided in the mold B.

If the mounting boss 42 is individually convex, the mold B will be undercut, but since the mounting boss 42 is provided with a stepped portion as in the present invention, the inner side 47 of the stepped portion is not provided in the mold B. There is.

Effects of the Invention As described above, the present invention has the following effects. (1) Since the safety switch is not installed on the top surface of the outer box,
A beautiful appearance can be provided without causing sink marks on the upper surface.

(2) Since the safety switch is not attached to the top surface of the outer box, even if some external force is applied to the top surface, the safety switch is not directly affected by deformation and deflection, and can operate normally. In addition, since the safety switch is linked to the lid, if the installation pace changes, the on/off angle of the safety switch will vary due to opening and closing of the lid, which will impair safety. Installing a switch has the effect of solving all of the above problems.

■) Since the safety switch itself is attached to the bottom, water and steam from splashing washing water from inside the main unit only wets the bottom of the safety switch, and the main body of the safety switch is located inside the panel chamber. , the occurrence of rust, etc. can be prevented. Furthermore, no cover is required, making it possible to streamline installation.

(4) Since the step portion is provided on the bottom surface, the same reinforcing effect as when the bottom surface itself has a flange shape can be achieved.

(5) Since the panel room has a bottom surface and becomes a box,
The overall strength is increased compared to the conventional one.

(6) Since it has a stepped part on the bottom, it can be installed by changing the mold arbitrarily to match the position of the safety switch, and if the stepped part is extended to the rear, the safety switch can be installed at the rear. It is possible.
