DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine provided with a top cover on an upper part of a main body.

[0002]

FIG. 7 shows an example of a conventional construction of a top cover portion of this type of washing machine. In this apparatus, a top cover 2 provided on an upper portion of a main body 1 of a washing machine includes a frame-shaped base member 3 surrounding a laundry entrance 3a, and a control disposed at a front upper surface of the base member 3. It is composed of a panel 4 and a rear cover 5 arranged at the rear of the upper surface of the base member 3.

[0003] The base member 3 has a housing 6a with an open upper surface at the front, housings 6b and 6c with lower surfaces opened at both left and right sides, and a rear portion. Attachments 6d, 6e, 6f are formed.
Among these, an operation unit 7 is disposed in the front storage section 6a, and the operation unit 7 is covered from above by the control panel 4. A water level sensor 8 is housed in the left housing part 6b, and the water level sensor 8 is covered from below by a water level sensor cover 9. The resistance mounting base 10 to which the resistance 10a is mounted is mounted to the right housing part 6c from below. In the rear mounting parts 6d, 6e, 6f,
A bath water pump 11, a water injection case 12, and a water supply valve 13 are respectively provided. These pump 11 and water injection case 1
2 and the water supply valve 13 are covered by the rear cover 5.

[0004] Among the internal components attached to the top cover 2, the operation unit 7 as one of the electrical components and other electrical components (water level sensor 8, resistor 10a, pump 11, water supply valve 13) are not shown. The predetermined electrical components connected by the lead wires and including the operation unit 7 are provided in the outer box 1a of the main body 1.
It is connected to the main body 1 via lead wires 14 wired inside.

[0005] At the right front portion of the base member 3, a level 1
5 is attached. In the control panel 4,
A panel 16 is mounted on the upper surface corresponding to the operation unit 7, and a screw insertion hole 4a is formed in the right part, and a screw cap 17 is mounted here. The screw cap 17 is for hiding a screw (not shown) for fixing the control panel 4 to the base member 2. On the upper surface side of the center of the base member 3, a washing lid 18 for opening and closing the laundry entrance 3a is provided. Washing lid 18
Is, for example, a two-fold type, and the handle cover 19 and the decorative plate 2
0 is attached.

The above-mentioned conventional configuration has the following disadvantages. That is, the internal components provided in the top cover 2 are configured to be attached to the base member 3 from both the upper surface side and the lower surface side thereof. For this reason, it is necessary to remove the control panel 4 and the rear cover 4 or to remove the entire top cover 2 and perform the work upside down, particularly during maintenance for repairing and checking the internal parts, which is troublesome. Further, when the top cover 2 is turned over, since the top cover 2 side and the main body 1 side are connected by the lead wire 14, the operation is more difficult. For the same reason, it is difficult to perform an assembling operation during manufacturing.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to improve the workability during maintenance of internal parts in a top cover and to improve the workability in assembly during manufacture. To provide a machine.

Thus, the button portion 79 is covered by the sheet member 80 from above.

A positioning hole 82 is formed at the front of the upper surface of the cover member 33, and a positioning projection 83 provided on the panel 55 is engaged with the positioning hole 82. The positioning holes 82 and the positioning projections 83 constitute a positioning portion. With this engagement, the positioning between the panel 55 and the cover member 33 and between the operation surface 80a of the sheet member 80 and the button portion 79 are performed. Have been.

In this case, when the operation surface 80a of the sheet member 80 is pressed, the button portion 79 is displaced downward through the operation surface 80a, and the operation member 78a of the switch 78 can be pressed by the button portion 79. It has a configuration that can be used.

In the third embodiment having such a configuration, the positioning portions 72 and 73 of the base member 32 are
With the positioning portions 74 and 75 in the cover member 33, the operator 7 of the switch 78 in the operation unit 40 is used.
The positioning between the operation unit 40 and the cover member 33, including the positioning between the 8a and the button portion 79, is reliably performed, and the positioning holes 82 of the cover member 33 and the positioning projections 83 of the panel 55 allow the positioning. Positioning between the cover member 33 and the panel 55, including positioning between the button portion 79 and the operation surface 80a, is reliably performed.

FIG. 6 shows a fourth embodiment of the present invention. The fourth embodiment differs from the first and third embodiments in the following points. That is, in the lower part of the base member 32, an engaging protrusion 85 is integrally provided at a position near the reinforcing plate 24, an engaging hole 86 is formed in the reinforcing plate 24, and the engaging protrusion 85 is connected to the engaging hole 86. Is engaged.

In the case of such a configuration, the engaging projection 85 is engaged with the engaging hole 86 so that the base member 32
Can be temporarily fixed to the main body 21, the assemblability can be further improved, and the number of screwed portions can be reduced.
