Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a washing machine in which the upper opening of the tub is opened and closed by a lid.

(b) Prior art A washing machine in which a washing tank and a water storage tank are arranged side by side in the machine frame and water is exchanged between the two tanks to reuse the water is disclosed in Japanese Utility Model Application Publication No. 193381/1981. has been done. A lid is provided at the upper opening of both tanks, and the lid is opened when cleaning limescale, etc. in the water storage tank. If the lid rotates when the lid is opened, if a dryer is placed above it, it will collide with the dryer, and also hides the operation surface of the control box. Therefore, the lid of this water tank is designed to be removed, but in the conventional example, the removed lid was placed around the machine frame, and could be accidentally stepped on and damaged.

(c) Problems to be solved by the invention The present invention aims to securely secure the removed lid to the aircraft body to prevent damage accidents.

(d) Means for solving the problem The present invention solves the problem by forming the engaging part surrounding the upward protruding piece provided on the outside of the machine body with an engaging piece and a screen-like rib on the lid. Solve.

(E) Effect: In other words, since the engaging portion surrounds the protrusion, the engaged relationship is maintained even when the lid is moved back and forth or left and right, and the removed lid is securely fixed to the body.

(F) Example To explain based on the drawings, 1 is a frame of a washing machine body made of a metal plate, and a plurality of hanging rods 2 are attached to the upper part.
... are attached, and the outer tank 3 is suspended by these hanging rods 2 in a vibration-proof manner. In addition, 4 is an inner tank provided in the outer tank 3 that also serves as a dehydration tank, and has a large number of dehydration holes 5 formed in the peripheral wall, and a large diameter pulsator 6 in the shape of a chevron in the center of the inner bottom. There is.

The outer bottom of the outer tank 3 is equipped with a drive motor 7 for rotating a pulsator 6 during washing and for rotating the inner tank 4 during dehydration, a bearing case 8, and a drain port 9. . Drain port 9
is connected to the outside of the machine by a drain hose 11 via a drain electromagnetic valve 10 that opens when excited.
Reference numeral 12 denotes an overflow port of the inner tank 4 provided in the outer tank 2, which is communicated with the drain hose 11 via an overflow hose 13. 14 is a water supply port for supplying water to the inner tank 4.

15 is a water tank attached to the side of the machine frame 1;
Reference numeral 6 denotes a resin top plate that is attached to the upper part of the machine frame 1 and the water tank 15 at the same time. This top plate 16 has an upper opening 17 of the inner tank 4 and an upper opening 18 of the water storage tank 15.
The upper opening 17 is provided with a rotating washing machine lid 19, and the upper opening 18 is provided with a removable water tank lid 20.

The top plate 16 has bulges 21 and 22 sandwiching the front and rear sides of the upper opening 18, locking holes 23 and 23 are formed in the vertical plane of the front bulge 21, and a rear bulge. Horizontal mounting hole 24 on the vertical surface of 22
is formed. Further, the top plate 16 has a rectangular protrusion 25 that protrudes upward on its outer surface corresponding to the outer side of the body.

On the other hand, the water storage tank lid 20 is formed into a box shape, and has a knob 26 protruding outwardly from the mounting end on the rear surface, which fits and is fitted into the mounting hole 24, and a knob 26 on the front surface. Claw pieces 27, 27 are formed that slide into and engage the locking holes 23, 23 from above. This nail piece 2
7 and 27 have elasticity by providing notches 28 on both sides. In addition, this water tank lid 20
An engaging piece 29 of a predetermined width is integrally formed so as to extend inwardly from the knob 26, and ribs 30, 30 are integrally formed in the shape of a screen from both ends of this engaging piece 29 to the rear surface. The engagement piece 29 is attached to the rear surface and the ribs 30, 3.
0 is defined as the engaging portion 31.

The control box of this washing machine is located at the front bulge 21.
One is provided laterally so as to be continuous with the other part, and the other is provided laterally in a further rear part of the rear bulging part 22.

Thus, when transferring the used detergent liquid or rinse water in the inner tank 4 to the water storage tank 15, the valve 32 is opened and the reversible pump 3 is activated on the condition that there is no liquid in the water storage tank 15.
Rotate 3 in one direction. Then, the liquid in the inner tank 4 moves to the water storage tank 15 through the water pipe 34. On the other hand, when reusing the liquid in the water storage tank 15, the valve 32 is opened and the reversible pump 33 is rotated in the other direction on the condition that there is liquid in the water storage tank, and the liquid in the water storage tank 15 is transferred to the water pipe. 34 to the inner tank 4. When the detection means 35 detects that there is no liquid in the water storage tank 15, the valve 32 is closed and the reversible pump 33 is stopped.

Here, when it is desired to remove water scale or the like from the water tank 15, the claw pieces 27, 27 are removed from the locking holes 23, 23, and the knob 26 is pulled out from the mounting hole 24. Then, the engagement portion 31 of the removed lid 20 is placed over the protrusion 25 . Then, the rear surface is placed on the upper end of the protruding piece 25, the ribs 30, 30 face the front and rear end surfaces of the protruding piece 25 with a short interval, and the engaging piece 29 is placed on the inner surface of the protruding piece 25. Almost close. Further, the end surface of the front surface is close to or in contact with the outer surface of the water tank 15. Therefore, the lid 20 is stopped substantially immovably with the engaging portion 31 engaged with the protruding piece 25. By holding the lid 20 in this manner, accidents such as being stepped on and damaged are eliminated.

When the lid 20 is to be reattached to the upper opening 18 after cleaning, lift the locked lid 20 with the knob 26 to disengage it, fit the knob 26 into the mounting hole 24, and then tighten the lid 20. Use the front part of the lid 20 as a fulcrum to push down. Then, the claw pieces 27, 27 slide downward along the vertical plane and are elastically engaged in the locking holes 23, 23. By closing the lid in this manner, the lid 20 is fixedly positioned both on the front, rear, right and left sides.

(g) Effects of the invention According to the invention, the removed lid can be stopped on the aircraft body, and the movement of the stopped lid is suppressed, which eliminates the accident of damage to the lid and improves usability. It is possible.
