Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an operating device for a washing machine.

[Conventional structure and its problems] Mechanical time switches, such as gear-type clockwork time switches, have traditionally been used on the operation panels of washing machines, etc., but in recent years, electronic printed circuit boards have been used. One-piece integration has been considered.

These printed circuit board controller units (referred to as controllers) are equipped with many tiny electronic chips, so unlike traditional clockwork time switches that are housed in sturdy cases, there are considerable restrictions on how they can be handled. Damage or deformation of the controller part during parts replacement during repairs, etc., was a problem.

[Purpose of the invention] The present invention solves the above-mentioned conventional problems.
This not only improves waterproofness but also prevents damage and deformation of the controller part during maintenance and inspection.

[Structure of the invention] In order to achieve the above object, the invention disposes a drain plate above the controller mounted inside the operating panel of the washing machine so as to cover the controller,
Guide ribs formed wider than the width of the controller are provided on both sides of this draining plate, and a substantially triangular extension is provided below the controller from the guide rib, and the lower edge of this extension is connected to the flange of the aquarium body. It is connected to or close to the upper edge of the part.

[Description of Embodiment] Hereinafter, an embodiment of the present invention will be described based on the drawings.

In FIG. 1, 1 is an outer box body, 2 is a water tank body installed inside the outer box body 1, including a washing tank (not shown),
It has a dehydration tank 3. Reference numeral 4 denotes a dehydration basket built into the dehydration tank 3, and a dehydration hatch 5 having a cloth input port (not shown) and a dehydration lid 6 supported on a shaft so as to be openable and closable are attached to the upper part of the basket. 7 is a panel stand with a power switch 8; 9 is a washing lid; 10 is an operating section; 11
is a pedestal. 2 and 3 are detailed views of the operation part 10 in FIG. 1, and 12 is a substantially rectangular opening provided at the front of the water tank body 2 and located on the dehydration tank 3 side. , its lower end is engaged with a holding portion 14 formed at the upper end of the outer box body 1 through a substantially shaped flange portion 13 . Reference numeral 15 denotes an operation plate holding plate attached to cover the opening 12, and its upper part is a hook part 16, and the holding plate 15 is attached to the aquarium main body 2.
The lower end engages with the protrusion 17 of the flange 1.
At the claw portion 18 to engage with the lower end of the aquarium body 2
is fixed to. Reference numeral 19 denotes an operation panel, on the top surface of which is pasted an operation sheet 20, on the back surface of which a plurality of bosses 21 are extended, and on the bosses 21 there is a controller mounted with a large number of electronic chips 22 on printed circuit boards. 23 boards 24 are attached with screws 25. Reference numeral 26 denotes an operation button section formed integrally with the operation panel 19, and a push button switch 27 is disposed below the operation button section. 28 is the operation panel 19
The drain plate is integrally formed with the drain plate and installed in the opening 12, and has an undercut portion 29 at the upper end, which acts as a guide to allow water droplets to flow to both sides even if they flow from the upper surface. Reference numeral 30 denotes guide ribs extending on both sides of the drain plate 28, and guide ribs 30 are provided on both sides of the drain plate 28, and guide ribs 30
A substantially triangular extension 31 extending downward from 4
The distal end portion 32 is formed in a substantially arc shape. This guide rib 30 is formed wider than the width of the controller 23, and its lower edge 33 is disposed in a position that engages with or is close to the upper end of the flange portion 13 of the water tank body 2. 34 is a connector, and 35 is a lead wire.

In this embodiment, the waterproofness of the controller 23 is improved by providing the guide ribs, as described above, because the controller 23 is protected by the guide ribs 30 provided on both sides of the drain plate 28, and the guide ribs are formed in a substantially shape. The reinforcement effect of the operation panel 19 and the strength of the mounting part of the controller 23 are increased. Furthermore, by bringing the lower edge portion 33 of the guide rib 30 into engagement with or close to the upper end of the flange portion 13, deformation of the upper portion of the operation plate holding plate 15 when pushed downward is also prevented.
Furthermore, when removing the operation plate holding plate 15 for repairs, etc., the guide rib 30 is formed with a larger dimension than the controller 23, so the controller 23 can be removed without directly touching the area around the opening 12 of the aquarium body 2. It can be easily removed,
The substantially arc-shaped tip 32 serves as a guide during insertion, allowing smooth installation without damaging the controller 23. In addition to the guide ribs on both sides, the same effect can be obtained even if a guide pin or the like is placed close to the outer periphery of the controller and placed from the back of the operation panel.

[Effects of the invention] Hereinafter, the present invention can improve the waterproofness of the controller attached to the back of the operation panel, and also prevents the controller from being attached or removed when reinforcing or repairing the operation panel. It has a simple structure and a great practical effect, as it can be done smoothly without causing any damage.
