The specific embodiment

Below, use accompanying drawing that embodiments of the invention are described.

Fig. 1 is the figure of outward appearance of the tumbling-box washing machine 100 of expression the present embodiment, (a) is top view, (b) is front view.

As shown in Figure 1, tumbling-box washing machine 100 has the housing 1 that consists of gabarit by combined steel plate and resin forming product.Housing 1 possesses pedestal 1f,

left side plate

1a, 1b, radiator grille 1c, back side cover 1d and upper face shield 1e is installed in the top of pedestal 1f, forms the housing 1 of case shape.

The substantial middle of covering in front 1c forms the input port that the washings such as clothing are taken out or put in cylinder, the door 7 that opens and closes when taking out by this input port or putting into washings can utilize linkage openedly and closedly to install.Be provided with the handle 7a for the locking mechanism of removing door 7 on the right side of door 7.By handle 7a is drawn to the front, locking mechanism is removed and is opened door 7, by door 7 is pressed to radiator grille 1c, locks and closes.

In addition, dispose for the drawer type detergent box (washing agent throw-in part) 11 that drops into washing agent, finishing agent etc. on the top of housing 1, be provided with guidance panel 6 on the right side of this detergent box 11.

In addition, not shown, in the housing 1 of tumbling-box washing machine 100, possess as the cylinder of the sink of folding and unfolding clothing, the water jacket of built-in this cylinder.And, can by utilizing CD-ROM drive motor to make to be combined in the axle rotation on the cylinder, carry out washing procedure, rinsing process, dehydration procedure etc.In addition, in the present embodiment, tumbling-box washing machine is narrated, but certainly can be the washing machine with functions/drying.

Such as Fig. 2, shown in Figure 3, this guidance panel 6 possesses power switch 2, console switch 3, program setting dial 4 and liquid crystal display part 5 etc.At this, console switch 3 is the buttons for appropriate change wash time, rinsing number of times etc., and program setting dial 4 is suitably selected the running contents such as accurate operation or woollen blanket operation.When making 4 rotation of this program setting dial, corresponding running program replaces successively, the display elements such as LED 8 bright lights in the place by being positioned at this running program content of expression, thus notify the user.

In addition, program setting dial 4 arranges coaxially with rotary encoder 9, when the rotating part of rotary encoder 9 is followed the rotation of program setting dial 4 and when rotating, and the rotation of the test section trace routine setting dial 4 of rotary encoder 9.This rotary encoder 9 contacts the outgoing position signal by the contact that is located on the rotating part with contact on being connected to lead-out terminal.

Then, use Fig. 6 explanation to be provided with the structure of the substrate 10 of rotary encoder 9 grades.

As shown in Figure 6, except the display elements such as LED 8, the bottom surface of rotary encoder 9, support component 11 is configured on the common substrate 10.Support component 11 have be used to insert a plurality of display elements 8 and the element installation portion 11a that supports, be positioned at the outer circumferential side of rotary encoder 9 and along its axially extended ring-type wall 11b, be located at the front of this ring-type wall 11b and be used for keeping the auxiliary section 11c of loading and unloading parts.Because the auxiliary section 11c at the concavity of this support component 11 is equipped with rubber sheet gasket 13, can prevent that therefore sealing immerses rotary encoder 9 from the inboard of program dial 4.

Then, use Fig. 4～Fig. 6 to potting resin 14 on substrate 10, be used for that installing component is carried out damp proof processing and describe.

At first, display element 8, rotary encoder 9 and support component 11 are installed in (step S1) on the substrate 10.

Then, as shown in Figure 4, will be entrenched on the auxiliary section 11c of support component 11 as the fastening section that resin immerses the resin injection accessory cover 15 that prevents parts, cover the front (step S2) of rotary encoder 9.

Afterwards, as shown in Figure 5, lean on outer circumferential side from being located at than ring-type wall 11b, and the resin injection mouth 11d(of the upper surface of support component 11 is not shown) injection urethane resin (step S3).After the injection, it is whole that resin 14 spreads all over the upper surface of substrate 10, and resin 14 is from the bottom of the ring-type wall 11b of support component 11 and interior all sides of the ring-type wall 11b of the gap immersion support component 11 of substrate 10.But the auxiliary section 11c of ring-type wall 11b from its bottom to front end of support component 11 forms the next door very close to each otherly, and, at auxiliary section 11c resin injection accessory cover 15 is installed.Therefore, prevent the leakage of air to resin injection accessory cover 15 from the height and position on the surface of resin 14, the liquid level of resin 14 of inboard that immerses the next door is lower than the liquid level in the outside in next door.That is, the zone of inboard, rotary encoder 9 residing next door is airtight conditions, so the liquid level of resin 14 extremely is difficult to rise.Specifically, when resin by injection, even the junction surface of the base of the aspect ratio rotary encoder 9 of the resin 14 in the outside in next door is high, also the height of the resin 14 of the inboard in next door is suppressed lowlyer than the junction surface of the base of rotary encoder 9.

At this, immerse the occasion of the components interior of rotary encoder 9 from the junction surface of base at resin 14, exist hinder be located at the contact on the rotating part with the contact that is connected on the lead-out terminal between conduction, damage the possibility as the performance of rotary encoder 9.But, be airtight conditions by the inboard that makes as mentioned above the next door, prevent that resin 14 from entering the components interior of rotary encoder 9, as a result of, improve the reliability of rotary encoder 9.

Then, unload resin injection accessory cover 15, replace and rubber sheet gasket 13 is installed in the auxiliary section 11c upper (step S4) of support component 11.

At last, as shown in Figure 6, in the fastening section that is connected to the state lower support program setting dial 4 on the slip face of support component 11, the bottom surface central indentation of program setting dial 4 is entrenched in the rotating part (step S5) of the front of rotary encoder 9.

As mentioned above, according to the present embodiment, because display element 8 and rotary encoder 9 are arranged on the common substrate 10, therefore do not need to connect the distribution of display element 8 and rotary encoder 9, not only improve productivity, can also improve the axial adjustment precision.In addition, even enforcement utilizes the occasion of the anti-wet process of resin 14 after being arranged on display element 8 and rotary encoder 9 on the common substrate 10, also be arranged on the next door of the circumferencial direction that covers on the whole rotary encoder 9, therefore can prevent the components interior that resin 14 immerses rotary encoder 9.
