Description

[Detailed Description of the Invention] This invention relates to a washing machine that includes a base having an upstanding wall formed on the outer periphery and an outer casing placed and fixed on the base.

The details will be explained below with reference to the drawings showing one embodiment.

In the figure, reference numeral 10 denotes a base made of synthetic resin, and an upright wall 10a is formed on the outer periphery of the base, and legs 11 extending downward are fixed to the lower surfaces of the four corners, respectively.

Reference numeral 12 designates an outer casing of the washing machine made of synthetic resin that is placed and fixed on the upright wall 10a of the base 10, and both upper and lower surfaces thereof are open.

Reference numeral 13 denotes a washing tank made of synthetic resin that is inserted into the outer casing 12 and opens upward, and a flange portion 13a that projects laterally from the edge of the opening is placed on the upper end of the outer casing 12.

14 is a control box fixed on the washing tank 13.

Reference numeral 15 denotes a horizontal wall that protrudes substantially horizontally inward from the lower end of the outer casing 12, and is formed over the entire circumference of the outer casing 12.

16 is a hanging wall extending downward from the tip of the horizontal wall 15;
Reference numeral 17 denotes four notches formed at appropriate intervals in the lower front surface of the outer casing 12, and are formed from the tip side of the horizontal wall 15 to the hanging wall 16 so as to leave the lower end portion of the hanging wall 16. has been done.

Reference numeral 18 designates first latching claws extending upward from the upper end of the upright wall 10a of the base 10, and four latching claws are provided corresponding to the notches 17.

The first latching claw 18 has a claw portion 18a extending outward in a hook shape at its upper portion.

Reference numeral 19 indicates a through hole formed in the horizontal wall 15 at the lower rear surface of the outer casing 12 at appropriate intervals, and reference numeral 20 projects from the upper end of the upstanding wall 10a of the base 10 in correspondence with the through hole 19. The upper portion of the hook protrudes outward in a hook shape and passes through the through hole 19 to lock the outer casing 1.
It has a claw portion 20a that can be engaged with the upper surface of the horizontal wall 15 of No. 2.

Reference numeral 21 denotes a screw that passes through the base 10 and is screwed onto the outer casing 12.

22 is a mounting screw that passes through the flange portion 13a of the washing tank 13 and is screwed onto the outer casing 12 (see FIGS. 1 and 3).
), this mounting screw 22 allows the washing tank 13 to be attached to the outer casing 12.
Fixed.

23 is a metal decorative plate attached to the front part of the flange portion 13a of the washing tank 13, and the mounting screw 2
2 is covered by this decorative board 23.

In the case configured as described above, the assembling of the base 10 and the outer casing 12 is as follows: First, the outer casing 12 is lifted onto the base 10, and the rear side of the outer casing 12 is moved to the front side. When the outer casing 12 is tilted by lifting it up higher than that, and after inserting the first latch claw 18 into the notch 17, the upper end of the upright wall 10a of the base 10 is brought into contact with the lower surface of the horizontal wall 15. The claw portion 18a of the first hooking claw 18 engages with the upper surface of the horizontal wall 15, and the second hooking claw 20 curves to open the through hole 1.
After passing through 9, its claw portion 20a due to its own elastic action
engages the upper surface of the horizontal wall 16.

Thereafter, when the screw 21 passing through the base 10 is screwed into the outer casing 12, the base 10 and the outer casing 12 are fixed.

At this time, in this embodiment, in the assembled state, the first latching claw 18 comes into contact with the remaining lower end portion of the hanging wall 16, as shown in FIG. The engagement between the latch claw 18 and the outer casing 12 is difficult to remove.

The through hole 19 is formed so that the claw portion 20a of the second latch claw 20 can pass therethrough, so that there is no space between the rear surface of the second latch claw 20 and the hanging wall 16 in the assembled state. A gap is created, and compared to the case of the first latching claw 18, the second latching claw 20
Although the engagement with the outer casing 12 tends to come loose somewhat, there is no problem in practical use.

However, in this embodiment, the second latching claw 20 side is also fixed with a screw 21 in case of an emergency.

As explained in detail above, this idea is possible with the outer casing tilted.
A locking claw protruding from the upper end of the upright wall of the base is inserted into a notch formed at the bottom of the outer casing, and then the claw is engaged with the upper surface of the horizontal wall to fix the base and the outer casing. Therefore, the horizontal wall of the outer casing can be held without any gap between the hook-shaped outwardly extending claw portion of the latching claw and the base upright wall, and the work of assembling the base and the outer casing is extremely simple.

In addition, since the engagement between the latch claw and the outer casing is held by the lower end portion of the remaining hanging wall, it is possible to securely fix the base and the outer casing in case it comes off, and it is possible to securely attach the base to the outer casing. As is well known, when a motor is attached, the relative position between the washing tank and the motor can be reliably fixed, and stable belt transmission can be ensured, which has many practical effects.
