As shown in Figures 1 to 6, the washing machine of present embodiment at least comprises: washing and dewatering groove 1 (hereinafter referred to as " inside groove "), and it is installed in the Storage water tank 40 (hereinafter referred to as " tank ") of body of the washing machine 2 inside and the rotating shaft of motor (not shown) supports to rotate mode freely; Top gabarit 3, it is mounted to the top integral body that roughly covers body of the washing machine 2, for example, with polypropylene molded; And operating means 50, it possesses supply unit 60.And inside groove 1 rotation is freely installed in tank 40 inside, in the bottom of tank 40, motor is installed.In addition, in the present embodiment, illustrate the washing machine with tank 40, but can certainly be only to there is inside groove 1 and the washing machine without the structure of tank 40.

Substantial middle (comprising central authorities) in top gabarit 3, is formed with clothes inlet 4 integratedly with top gabarit 3.Now, the in the situation that of upright type washing machine, clothes inlet 4 is configured to downward direction and extends towards the top of inside groove 1.

In addition, the face side (left side that is equivalent to Fig. 1) in top gabarit 3 is formed with the roughly resettlement section 5 of concavity (comprising concavity).As shown in Figure 5, at the roughly the same width of the integral width of the face side of body of the washing machine 2 and Yi Yu top, the position gabarit 3 between clothes inlet 4 (with the direction of the paper quadrature of Fig. 1), be provided with resettlement section 5.And, resettlement section 5 roughly whole had be printed onto for example display part 6 of PET sheet (polyethylene terephthalate sheet) and for example covering with polypropylene molded guidance panel 8 of action button 7.In addition, at the back side of display part 6, except the perforate at the position corresponding with action button 7, be roughly for example provided with on the whole two sides adhesive tape (not shown), via two sides adhesive tape, display part 6 sticked on to the surface of guidance panel 8.

In addition, in position configuration corresponding to action button 7 with guidance panel 8, there is the console switch 10 that is installed on operation substrate 9.

And, the in the situation that of operating washing machine, be configured to from being equivalent to the inner side of bottom 5a of resettlement section 5 the arranged in order parts of surface to operate substrate 9, console switch 10, action button 7, display part 6 and arrive the operated operating surface 6a of user.That is to say, user is by pressing the operation button 7 from operating surface 6a, and via the action button 7 of guidance panel 8, operation is input to operation substrate 9.Thus, user can select running, the washing action of washing machine.

In addition, in resettlement section, 5 inside are equiped with the operating means 50 that possesses supply unit 60.Operating means 50 at least consists of supply unit 60, guidance panel 8, operation substrate 9 and boat shape containment vessel 13 (being roughly called below " containment vessel 13 ").Now, containment vessel 13 is for example shaped with flame-proof ABS resin, and for example cross sectional shape is roughly H shape (comprising H shape), at least has two recess 13a, 13b.The operation substrate 9 of operating means 50 is installed in the recess 13a inside of containment vessel 13.

In addition, supply unit 60 at least consists of encapsulation agent 24 and the containment vessel 13 of power supply board 11, covering power supply board 11.Specifically, the recess 13b inside that supply unit 60 is configured at containment vessel 13 is equiped with packed dose 24 power supply board 11 covering.Power supply board 11 is controlled and is provided being installed on the electric power of motor (not shown) even load of the bottom of inside groove 1.

That is to say, at the inner installing operation of the recess 13a substrate 9 of one side side (with the opposite side of guidance panel 8) that forms the containment vessel 13 of operating means 50, such as it is protected to avoid by infringements such as water.On the other hand, in the recess 13b inside of the another side side (with the opposite side of bottom 5a of resettlement section 5) of containment vessel 13, be equiped with the power supply board 11 that forms supply unit 60, such as it is protected to avoid by infringements such as water.Now, operation substrate 9 is not encapsulated the filling of agent and is processed, and only to power supply board 11, utilizes encapsulation agent 24 to fill and processes and covering power supply board 11.Thus, operation substrate 9 need not bear thermal stress, the encapsulation agent 24 of encapsulation agent 24 while solidifying and shrinks the mechanical stress causing.

In addition, as shown in Figure 2 and Figure 5, operation substrate 9 by operation substrate install screw 15 be fixed near action button 7, install in projection 14 with the operation substrate of guidance panel 8 integrally formed settings.Specifically, by making to operate substrate, screw 15 is installed is connected near the perforate (not shown) console switch 10 on operation substrates 9 and be fastened to operation substrate projection 14 is installed, will operate substrate 9 and fix with guidance panel 8.

In addition, as shown in Figure 1, the operating surface 6a of the position corresponding with action button 7 of display part 6 forms with protuberance shape towards foreign side.Now, design gaps g1 between display part 6 and action button 7, design gaps g2 between action button 7 and console switch 10.And console switch 10 is set to until to open and close the stroke of circuit be s1.And the height h1 of the protuberance shape of display part 6 is configured to the relation that meets following (formula 1).

(formula 1)

h1×2≥g1+g2+s1 (1)

And when pressing the operating surface 6a of protuberance shape of display part 6, operating surface 6a is to the rear displacement of console switch 10.Therefore, expanded material forms it highly for h1 by the protuberance shape of operating surface 6a in advance.That is to say, when push face 6a, the protuberance shape of operating surface 6a reversion, until the recess shapes of height h1, until the displacement of height h1 * 2, the material of operating surface 6a does not stretch and the enough slight operating physical forces of energy make operating surface 6a displacement.Now, as shown in (formula 1), the distance of operating surface 6a displacement height h1 * 2 is for to add to gap g1, gap g2 the value that up stroke s1 obtains.Thus, do not rely on the stretching, extension of the material that forms display part 6, just can be by the stroke s1 of most console switch 10 without the total travel of the operating surface 6a reversion of protuberance shape.

And, in a part for action button 7, at least in the face side setting of washing machine, extend to than console switch 10 7a of the portion that dewaters of position on the lower also.Thus, for example in the situation that the back side of guidance panel 8 (resettlement section 5 sides) steam condense, prevent the water droplet condensing fall be installed on operation substrate 9 console switch 10.

And; even in the situation that it is outstanding from the back side of operation substrate 9, power supply board 11 to be installed on the leading part (not shown) of parts such as forming the operation substrate 9 of operating means 50 and the leading part 10a such as console switch 10 of power supply board 11, connector 22, also at the first resin bed 13c, the second resin bed 13d that do not fire cover 21 containment vessel 13 high with insulating properties before contacting with first of containment vessel 13, contact.Therefore, can prevent the resistance between the leading part of parts to reduce.Its result, can realize and have the operating means 50 of the good supply unit of reliability 60 and can prevent the washing machine that malfunction, mistake show.

In addition; supply unit 60 is configured to: after power supply board 11 is fixed to containment vessel 13, such as the protection against the tide consisting of polyurethane resin etc. is filled into inside with encapsulation agent 24, has installed in the recess 13b of containment vessel 13 of power supply board 11 and covered the roughly whole of power supply board 11.

That is to say; operating means 50 by the first resin bed 13c, first of the action button 7 of display part 6, guidance panel 8, console switch 10, operation substrate 9, gap A, containment vessel 13 do not fire the second resin bed 13d of cover 21, containment vessel 13, filled space, the power supply board 11 of encapsulation agent 24, space, the connector 22, second of having filled encapsulation agent 24 do not fire cover 23, gap B forms, till the bottom 5a from display part 6 to resettlement section 5, be configured successively.In addition, gap A is equivalent to by the operation substrate 9 of console switch alignment pin 39 decisions and the space between the first resin bed 13c of containment vessel 13.Gap B is equivalent to the space being clamped by the second bottom 5a that does not fire cover 23 and resettlement section 5.

In addition; as shown in Fig. 1 and Fig. 6, the containment vessel 13 that forms at least display part 6, guidance panel 8, inner installing operation substrate 9 and the power supply board 11 of operating means 50 is configured to the face side to body of the washing machine 2 from clothes inlet 4 and towards face side (left side figure) downward direction, tilts respectively.

As mentioned above, form the washing machine of the operating means 50 that possesses the supply unit 60 with present embodiment.

Below, explain and be arranged at the first labyrinth part in operating means 50 and the 26S Proteasome Structure and Function of the second labyrinth part as the feature of present embodiment.

First, as shown in Figure 1, the first labyrinth part 17 consists of following part: a part that makes guidance panel 8 is extended downwards and the first rib 25 that obtains; And the cross sectional shape for example roughly forming on complete cycle of the end in resettlement section 5 of clamping first rib 25 is roughly the first groove 26 of U word shape (comprising U word shape).And, the gap design between first rib 25 and the first groove 26 is obtained narrow and form the first labyrinth part 17, realize thus water and be not easy to enter into the waterproof construction in resettlement section 5.Thus, form the first waterproof portion.

In addition, the roughly complete cycle of the first labyrinth part 17 refers to that a part forms the structure of breach because wiring, screw are fixing etc., and certainly not needing must complete cycle formation labyrinth structure.In addition, the first labyrinth part 17 can be also the structure of a part of butt of first rib 25 and the first groove 26, can access same effect.And the first labyrinth part 17 also comprises the situation that only the stop part 17a by be arranged at clothes inlet 4 sides on the width of washing machine shown in Fig. 5 forms.

Now, as shown in Figure 4 and Figure 5, resettlement section 5, the position corresponding with near screw hole 27a being arranged at the two ends, left and right (width) of clothes inlet 4 sides of guidance panel 8 be formed with guidance panel installed surface 28.Guidance panel installed surface 28 is to cut the first groove 26 of the end that is formed at resettlement section 5 and form, for example, have the lug boss 28a at two places.And, for example with two guidance panels, screw 27 is installed via guidance panel installed surface 28, by the screw hole 27a via guidance panel 8, at lug boss 28a, carry out screw and fix, guidance panel 8 is fixing with resettlement section 5.

In addition, as shown in Figure 1, the second labyrinth part 29 consists of following part: a part that makes guidance panel 8 is extended downwards and the second rib 30 that obtains; And the cross sectional shape forming on the roughly complete cycle of the peripheral end of the recess 13a at formation containment vessel 13 of clamping second rib 30 is roughly the second groove 31 of U word shape (comprising U word shape).And, the gap design between second rib 30 and the second groove 31 is obtained narrow and forms the second labyrinth part 29, realize thus water and be not easy to enter into the waterproof construction in the containment vessel 13 that operates substrate 9 sides.Thus, form the second waterproof portion.

In addition, the second labyrinth part 29 can be also the structure of a part of butt of second rib 30 and the second groove 31, can access same effect.

Now; as shown in Fig. 1, Fig. 3 and Fig. 5, the power switch 19 of the power supply board 11 of microcomputer 20 being installed and being installed on containment vessel 13 is installed in the outside in the inner side (in resettlement section 5) of the first labyrinth part 17 and the region by the second labyrinth part 29 waterproof in resettlement section 5.And, for drawing for power switch 19 being connected to the power switch encapsulation 44 of the lead-in wire 19a of source power supply, local by carried out encapsulation process such as epoxy resin etc.Thus, power switch 19 can waterproof for the water of invading from outside.In addition, connect power supply board 11 and be electrically connected to power supply board 11 with the lead-in wire 19a of power switch 19, and can waterproof by the encapsulation agent 24 of covering power supply board 11.

Thus, especially operation substrate 9 is not carried out encapsulation process and can carry out waterproof by the simple structure of the first labyrinth part 17 and the second labyrinth part 29.

In addition, in the present embodiment, will be connected with source power supply and for example make the high-current circuit that large electric current flows through motor even load be disposed at power supply board 11, and will low current Circnit Layouts such as the display parts such as LED 6, console switch 10 in operation substrate 9.Thus, the high galvanic areas can configured separate being formed by power supply board 11 high-current circuits such as grade and the low current region being formed by low current circuit such as operation substrates 9.Its result; even in the situation that for example condense because temperature reduces to produce in the region of the second labyrinth part 29 being formed by guidance panel 8 and containment vessel 13, do not need especially to fill the operation substrate 9 being formed by low current circuit and carry out waterproof countermeasure with encapsulation agent 24 yet.On the other hand, fill encapsulation agent 24 and cover power supply board 11 high-current circuits such as grade, therefore can be easily and prevent more reliably the short circuit that moisture etc. causes.

In addition, in the present embodiment, the roughly complete cycle of the edge part of operation substrate 9 is surrounded by second rib 30.Therefore, even in the situation that the current direction that invades resettlement section 5 from the first labyrinth part 17 produces the spittle while being formed at the osculum 18 of resettlement section 5, also can prevent that the spittle from invading in the region of the operation substrate 9 being surrounded by the second labyrinth part 29.And, even in the situation that enter into resettlement section 5 such as foreign matters such as insects from being formed at the osculum 18 of resettlement section 5, also can prevent that foreign matter from invading in the region of the operation substrate 9 being surrounded by the second labyrinth part 29.Its result, prevents the short circuit of the operation substrate 9 that the intrusion due to moisture, foreign matter etc. causes, thereby can prevent malfunction of washing machine etc.

In addition, in the present embodiment, as shown in Figure 2, the operation substrate 9 that forms operating means 50 is electrically connected to by flat cable 32 grades with power supply board 11.Therefore,, in order to draw flat cable 32, need to cut along the periphery of operation substrate 9 and cover a part for the second rib 30 of complete cycle roughly and form flat cable outlet 33.Now, conventionally, flat cable outlet 33 is arranged at the face side of opposition side and the washing machine that containment vessel 13 tilts of clothes inlet 4 downwards.Thus, water, because deadweight flows to below, therefore can prevent that water from invading operation substrate 9 sides that are configured in top.And, be made as following structure: the sheet material 34 of reeling and for example being formed by the foam rubber sheet with separated foam structure, the gap between obstruction and flat cable outlet 33 on flat cable 32.Thus, can seamlessly stop up the flat cable outlet 33 as the notch of second rib 30 by enough sheet materials 34.Its result, can prevent that moisture from invading operation substrate 9 via flat cable outlet 33.That is to say, even notch is set in a part for second rib 30, also can accesses with second rib 30 and be configured to cover along the periphery of operation substrate 9 effect that the situation of complete cycle is identical.Its result, can realize operating means 50 and the washing machine with the good supply unit of reliability 60.

In addition, in the present embodiment, as shown in Figure 1, Figure 4 and Figure 5, cut the part of the first groove 26 of the stop part 17a that the part in the first labyrinth part 17 of clothes inlet 4 sides forms and setting operation erecting of panel face 28.Therefore,, in the first groove 26 of clothes inlet 4 sides, guidance panel installed surface 28 becomes the minimum point of the first groove 26.

Therefore, the guidance panel installed surface 28 of the minimum point as the first groove 26 is formed on than the low position of height of the peak 31a that forms the second groove 31 of the second labyrinth part 29 (position that conventionally, is equivalent to the second groove 31 of clothes inlet 4 sides).

That is to say, be configured to height according to the peak 31a (upper end 31a) of the upper end 26a of the first groove 26, the second groove 31, be arranged at the guidance panel installed surface 28 of a part for the first groove 26, the order of osculum 18 reduces.In addition, be configured to the face side towards top gabarit 3, apart from clothes inlet 4, according to the order of the stop part 17a of the first labyrinth part 17, the second labyrinth part 29, operation substrate 9, flat cable outlet 33, become far away.

Thus, for example in the situation that water from clothes inlet 4, exceed the stop part 17a of the first labyrinth part 17 that forms the first waterproof portion and invade, because guidance panel installed surface 28 is the minimum point of the first groove 26, so water is only invaded and is flow into resettlement section 5 from the part of guidance panel installed surface 28.Therefore, water can not invaded from the peak 26a (upper end 26a) of the first groove 26.In this case, even if the flowing of water of invading due to the part from guidance panel installed surface 28 produces the spittle, also the peak 31a due to the second groove 31 can prevent that higher than guidance panel installed surface 28 water from invading in the region of operation substrate 9.

As mentioned above, according to present embodiment, can be by forming first labyrinth part 17 with stop part 17a of the first waterproof portion and preventing that as the dual structure of second labyrinth part 29 (labyrinth part 29) of the second waterproof portion (waterproof portion) water from invading operation substrate 9.Therefore, do not need to carry out waterproof with encapsulation agent 24 overlapping operation substrates 9.Thus, operation substrate 9 need not bear the thermal stress of encapsulation agent 24, the mechanical stress being caused by contraction, therefore can suppress to operate the warpage of substrate 9 parts such as grade.Its result, can make position deviation, the action button 7 and the display part 6 that are installed on guidance panel 8 of guidance panel 8 and operation substrate 9 and be installed on the relative position of console switch 10 of operation substrate 9 stable.And the deviation of stroke when inhibition user operates action button 7, can make operating physical force stable.

In addition, according to present embodiment, as shown in Figure 5 and Figure 6, for example open with round-shaped the top of inside groove 1 and tank 40, and for example Storage water tank cover 35 of ring-type (following, to be recited as " tank cover ") is installed in the upper end of the portion that opens as tank 40.Now, the osculum 18 that forms the first waterproof portion is configured in to the top of tank cover 35 and than the edge part of the circular of tank cover 35 (comprising circular edge part) region more in the outer part.That is to say, be configured to the scope that the water of discharging from osculum 18 can not drop onto tank cover 35 and inside groove 1.

According to this structure, for example in washing process in the situation that the foam that inside groove 1 produces exceed tank cover 35 and overflow, before arriving osculum 18, drop to body of the washing machine 2 below.Thus, prevent that foam from invading in resettlement section 5 from osculum 18, can prevent that foam from invading in the region of operation substrate 9 from the gap between containment vessel 13 and guidance panel 8 etc.Its result, can prevent to operate the short circuit of substrate 9, prevents malfunction, mistake demonstration of washing machine etc.

In addition, as shown in Fig. 1 and Fig. 6, osculum 18 be for example with the angle of 45 degree (comprising 45 degree) roughly towards the below of a side (outer circumferential side) contrary to inside groove 1, be face side lower opening and forming.Thus, the water that invades resettlement section 5 was discharged efficiently before accumulating the bottom 5a of resettlement section 5.And, even in the situation that the foam that comprises detergent ingredients producing from inside groove 1 overflows and crosses and pass to the back side 5b of resettlement section 5 from tank cover 35, also can guide foam into below by the inclined plane of osculum 18.Its result, can prevent that foam from invading in resettlement section 5 effectively.

In addition, in the present embodiment, in the stop part 17a of the first labyrinth part 17 that forms the first waterproof portion, between first rib 25 and the first groove 26 and between guidance panel 8 and guidance panel installed surface 28, be provided with design gaps and making it possible to the fitting portion of dismounting and the chimeric guidance panel 8 of guidance panel installed surface 28.Therefore,, when putting into and taking out clothing via clothes inlet 4, water can be invaded from design gaps.Therefore the total cross-sectional area S2 (following, to be roughly recited as " area S2 ") that, design forming design gaps makes to be equivalent to the aperture area of osculum 18 is greater than the total cross-sectional area S1 of design gaps.In addition, the total cross-sectional area S1 of design gaps refers in the situation that the summation of the area of section of the stop part 17a that upwards cuts off the first labyrinth part 17 week of the first labyrinth part 17 forming annularly.In addition, below, the total cross-sectional area S1 of the design gaps that the water of intrusion is circulated is roughly recited as the area S1 of stop part 17a.

Below, use Fig. 7 to specifically describe the reason that the area S2 of osculum 18 is made as to the area S1 that is greater than stop part 17a.

Fig. 7 is the structure of stop part and the major part sectional view of relative configuration relation in the washing machine of explanation present embodiment.In addition, a left side of Fig. 7 illustrates near the cross section of guidance panel installed surface 28 of stop part 17a.In addition, the right side of Fig. 7 illustrates the cross section of the stop part 17a that forms the first labyrinth part 17.

As shown in Figure 7, first, will be made as S01 with the area forming the face that current (arrow in the right figure of Fig. 7) mobile between the first rib 25 of stop part 17a of the first labyrinth part 17 and the first groove 26 are vertical.In addition, the area of the vertical face of the current with mobile between guidance panel 8 and guidance panel installed surface 28 (arrow in the left figure of Fig. 7) is made as to S02.And, as shown in Figure 7, the difference in height of the upper end 26a of the first groove 26 and guidance panel installed surface 28 is made as to h01.In addition, area S01 and area S02 sum are equivalent to the area S1 of stop part 17a.

Now, in the situation that the water of flow Q02 meets (formula 2), between the first rib 25 of area S01 and the first groove 26, flow out in resettlement section 5.

(formula 2)

$Q02>S02\×\sqrt{(2\·g\·h01)}---\left(2\right)$

But the flow velocity that flows through the water of area S01 is compared with the flow velocity that flows through the water of area S02, guidance panel installed surface 28 height h01 left and right are correspondingly slack-off with exceeding.

And, in the present embodiment, make the area S2 of the face vertical with the current that flow through osculum 18 be greater than the area S1 that area S01 and area S02 is added up to the stop part 17a obtaining.Therefore, in the situation that the flow that flow into resettlement section 5 is made as to Q1, with (formula 3), represent to flow through the flow velocity V1 of water of the area S1 of stop part 17a.On the other hand, in the situation that by 5 flows of discharging are made as Q2 from resettlement section, flow through the flow velocity V2 of the area S2 of osculum 18 with (formula 4) expression.

(formula 3)

V1＝Q1/S1 (3)

(formula 4)

V2＝Q2/S2 (4)

And, when being made as the water yield that flow into resettlement section 5 from the area S1 of stop part 17a and all only discharging from the area S2 of osculum 18, be Q1=Q2.But, in the present embodiment, being designed to S1<S2, the flow velocity V1 of water that therefore flows through the area S1 of stop part 17a forms with the flow velocity V2 that flows through the area S2 of osculum 18 relation that (formula 5) illustrates.

(formula 5)

V1>V2 (5)

In addition, when the water level of the inflow portion of stop part 17a is made as to H1 when (being equivalent to the height from guidance panel installed surface 28), with (formula 6), represent to flow through the flow velocity V1 of water of the area S1 of stop part 17a.

(formula 6)

$V1=\sqrt{(2\&CenterDot;g\&CenterDot;H1)}---\left(6\right)$

Similarly, when the water level of the inflow portion of the bottom of resettlement section 5 is made as to H2 when (being equivalent to the height from guidance panel installed surface 28), with (formula 7), represent to flow through the flow velocity V2 of water of the area S2 of osculum 18.

(formula 7)

$V2=\sqrt{(2\&CenterDot;g\&CenterDot;H2)}---\left(7\right)$

Therefore, known according to (formula 5), water level H1 and water level H2 become the relation that (formula 8) illustrates.

(formula 8)

H1>H2 (8)

That is to say, when being made as the area S2 of osculum 18 and being greater than the area S1 of stop part 17a, compare with the water level H1 of water that flows through the stop part 17a of the first labyrinth part 17, the water level H2 that accumulates in the water in resettlement section 5 must be low.Thus, can discharge reliably the water that invades resettlement section 5 via osculum 18.Its result, can prevent that water from invading operation substrate 9 reliably.

On the other hand, even for some reason and water level H1 and water level H2 be equal height in the situation that, according to (formula 6) and (formula 7), the flow velocity V1 of water that flows through the area S1 of stop part 17a becomes with the flow velocity V2 that flows through the area S2 of osculum 18 relation that (formula 9) illustrates.

(formula 9)

V1＝V2 (9)

But, in the present embodiment, be designed to S1<S2.Therefore,, according to (formula 3) and (formula 4), with (formula 10), represent to flow into the relation of the flow Q1 of resettlement section 5 and the 5 flow Q2 that discharge from resettlement section.

(formula 10)

Q1<Q2 (10)

That is to say, known according to (formula 10), the flow Q2 discharging from osculum 18 is greater than the flow Q1 that flow into resettlement section 5.Therefore, the water level H2 of 5 inside, resettlement section reduces immediately.Thus, the water yield that time per unit can be discharged from osculum 18 is more than the water yield that can invade from the stop part 17a of the first labyrinth part 17.Its result, even in the situation that water level H1 and water level H2 are equal height, also can be from osculum 18 draining effectively, thus can be reliably and effectively prevent that water from invading operation substrate 9.

In addition, in the present embodiment, as shown in Figure 7, in the stop part 17a of the first labyrinth part 17 that forms the first waterproof portion, first rib 25 is longer than the width W (cross-sectional width) of the first groove 26 by the length L (length of short transverse) of the part of the first groove 26 clampings.Thus, to narrow down and the elongated space that increases ponding through the path of the water of the stop part 17a of the first waterproof portion by making, can improve water resistance.

Similarly, the second rib 30 of the second labyrinth part 29 of formation the second waterproof portion is longer than the width (cross-sectional width) of the second groove 31 by the length (short transverse length) of the part of the second groove 31 clampings.Thus, by the path that will pass the water of the second waterproof portion is narrowed down and the elongated ponding space that increases, can improve water resistance.

As mentioned above, according to present embodiment, by the stop part 17a of the first labyrinth part 17 is made as to labyrinth structure, small-scale structure can be kept and to make to flow through the stream of water of the design gaps between first rib 25 and the first groove 26 narrow and long.Therefore, can reduce the flow of the stop part 17a that flows through the first labyrinth part 17 and prevent that efficiently water from invading operation substrate 9.

In addition, according to present embodiment, even in the situation that for example depart to body of the washing machine 2 the place aheads (left side of Fig. 1) position of the first rib 25 of guidance panel 8 owing to forming the machining deviation etc. of parts of guidance panel 8, resettlement section 5 etc., the gap between the front side of the body of the washing machine 2 of first rib 25 and the first groove 26 also narrows down.Therefore, can further prevent that by the stop part 17a of the first labyrinth part 17 water from invading resettlement section 5, therefore to the waterproof effect of operation substrate 9, can not reduce.Similarly, even in the situation that for example depart to body of the washing machine 2 rears (right side of Fig. 1) position of the first rib 25 of guidance panel 8, the gap of the rear side of body of the washing machine 2 also narrows down.Therefore, obtain effect same as described above.That is to say, by labyrinth structure, can effectively prevent that water from invading resettlement section 5.Its result, the operation substrate 9 being surrounded by the second labyrinth part 29 can waterproof.

In addition, according to present embodiment, by forming stop part 17a and the osculum 18 of the first labyrinth part 17 of the first waterproof portion, the water that can make to invade in resettlement section 5 is not easy to lodge in resettlement section 5.And by forming the second labyrinth part 29 of the second waterproof portion, the foreign matters such as the moisture dispersing producing during the water flow that can prevent from entering from the stop part 17a of the first labyrinth part 17, the steam entering from osculum 18, insect invade operation substrate 9.Its result, does not need to encapsulate agent 24 overlapping operation substrates 9 by filling and carrys out waterproof.

And operation substrate 9 need not bear the thermal stress of encapsulation agent 24, the mechanical stress being caused by contraction, therefore can suppress to operate the warpage of substrate 9 parts such as grade.Thus, can make position skew, the action button 7 and the display part 6 that are installed on guidance panel 8 of guidance panel 8 and operation substrate 9 and be installed on the relative position of console switch 10 of operation substrate 9 stable.Its result, the deviation of stroke in the time of can suppressing user action button 7 is operated and make operating physical force stable.

Describe particularly, in the situation that washing machine in the past, when with encapsulation agent 24 overlapping operation substrate 9, operation substrate, containment vessel warpage, therefore such as needing the operating physical force etc. of strengthen operation button 7 to have problems in operability.Therefore, need to reduce (dwindling) as shown in Figure 1 for example the gap g2 between action button 7 and console switch 10 alleviate operating physical force.But, when dwindling gap g2, if user applies power near 7 of the action buttons of guidance panel 8 mistakenly such as leaning on washing machine etc., even non-intention pressing operation button 7, console switch 10 is state in being pressed etc. also, easily causes malfunction.

Therefore, according to present embodiment, as shown in Figure 2, do not need with encapsulation agent 24 filling overlapping operation substrates 9, for example near console switch 10, operation substrate installation projection 14 and the operation substrate installation screw 15 by guidance panel 8 is directly fixed to guidance panel 8 by operation substrate 9.Thus, need not encapsulate agent overlapping operation substrate 9, therefore can prevent from operating the distortion of substrate 9, and easily operation substrate 9 is directly fixed to guidance panel 8.And, by directly fixing, can make to be not easy to produce position skew between the action button 7 of guidance panel 8 and the console switch 10 of operation substrate 9.Its result, by making action button 7 stable with size, the position relationship of console switch 10, suppresses the deviation of the operating physical force of console switch 10 can reduce malfunction.

In addition; according to present embodiment; between terminal, spacing is narrow and have few moisture just easily to carry out the microcomputer 20 of malfunction and be connected with source power supply and in order to prevent electric leakage, need the power switch 19 of waterproof not to be installed on operation substrate 9; and be installed on by the power supply board 11 of containment vessel 13 configured separate, and packed dose 24 covers.Therefore,, owing to microcomputer 20, power switch 19 not being installed on to operation substrate 9, even if therefore need not encapsulate 24 pairs of operation substrates of agent 9 carries out WATER REPELLENT TREATMENT, also can easily prevent the generation of malfunction, electric leakage.

And, according to present embodiment, do not need to cover power supply board 11 and cover with encapsulation agent 24 the operation substrate 9 being connected with power supply board 11 by flat cable 32 with encapsulation agent 24.Therefore, with encapsulation agent 24, only cover the operation substrate 9 that is accommodated in containment vessel 13 and the only power supply board 11 in power supply board 11.Its result, manufactures and becomes simple, and in resettlement section 5, can accommodate compactly for taking in the containment vessel 13 of operation substrate 9 and power supply board 11.

In addition, according to present embodiment, by forming the first labyrinth part 17 of the first waterproof portion, limit the water yield that invades resettlement section 5, and carry out draining with osculum 18.Thus, the water of invading is not easy to lodge in resettlement section 5, and can carry out expeditiously draining.And, the second labyrinth part 29 that forms the second waterproof portion is configured to labyrinth structure.Thus, can limit the water yield that invades operation substrate 9.Now, even in the situation that water flow into operation substrate 9 side from the second labyrinth part 29, water is also by being arranged at whole the second groove around, and the flat cable outlet 33 being formed slopely by the second rib 30 of the second labyrinth part 29 and a part of downward direction of the second groove 31 makes invaded current downward direction and can discharge.Its result, the water of invading flows in groove, and water can not flow in the region of having accommodated operation substrate 9, so water do not accumulate in operation substrate 9 sides, therefore can operate expeditiously the waterproof of substrate 9.

In addition, according to present embodiment, as shown in Figure 3, the power switch integrally formed with guidance panel 8 is set near the power switch 19 of containment vessel 13 projection 36 is installed, with power switch, screw 37 is installed containment vessel 13 is fixed on to guidance panel 8.Now, the power switch alignment pin 38 integrally formed with containment vessel 13 (power switch location division) is arranged to the position corresponding with power switch 19 (position) of containment vessel 13, makes power switch alignment pin 38 chimeric with the perforate of power switch 19.Thus, can prevent the position skew of power switch 19.

In addition, according to present embodiment, as shown in Figure 1, the console switch alignment pin 39 integrally formed with containment vessel 13 (console switch location division) is arranged to the position corresponding with console switch 10 (position) of containment vessel 13.Thus, near console switch alignment pin 39 operation substrate 9 butts with console switch 10.Its result, presses the operation button at 7 o'clock user, can prevent that console switch 10 downward directions that are installed on operation substrate 9 from moving.And, can make the operating physical force that is applied to console switch 10 stablize.

In addition, according to present embodiment, power switch alignment pin 38 and console switch alignment pin 39 is integrally formed on containment vessel 13.Therefore, user, press the operation button at 7 o'clock, the position of power switch 19, console switch 10 can not be offset.And, with operation substrate installation screw 15 and power switch, screw 37 is installed operation substrate 9 and containment vessel 13 screws is fixed on guidance panel 8.Therefore, the distance between guidance panel 8 and console switch 10 and power switch 19 is not subject to the impact of guidance panel 8, action button 7 and containment vessel 13 dimensional discrepancy in addition.Its result, can make the operating physical force that is applied to console switch 10 further stablize.

In addition, according to present embodiment, at least one in resettlement section 5, guidance panel 8 and containment vessel 13 is such as being shaped with flame retardant resins such as flame-proof ABS resins.Thus, even in the situation that power supply board 11 breaks down, also can prevent from prolonging burning etc. outside product.

In addition, in the present embodiment, with what formed by heat-resistant component, first do not fire cover 21 and second and do not fire cover 23 and by metallic plate, be configured to example and be illustrated, but be not limited thereto.Such as can not firing cover 21 and second by first, do not fire any in 23 of cover such as forming with incombustible materials such as the fire proofings such as ABS resin, micas yet.Thus, when manufacturing washing machine, do not have the restriction of the sequence of operation of installation etc., therefore design becomes easy.

In addition, in the present embodiment, for example understand the structure that action button 7 and guidance panel 8 are integrally formed, but be not limited thereto.For example, also can only form action button and form with the parts that separate with transparent material etc.Thus, can make action button 7 luminous and show in the mode of easily recognizing, and be integrally formed owing to not needing, therefore design becomes easy.

(embodiment 2)

Below, the washing machine that uses Fig. 8 supply unit, the operating means in embodiments of the present invention 2 is described and possessed these supply units, operating means.In addition, below, with embodiment 1 similarly, illustrate upright type washing machine.

Fig. 8 is supply unit and the operating means major part sectional view around of the washing machine in embodiments of the present invention 2.

That is to say; the difference of the washing machine of present embodiment and embodiment 1 is; replace to form operating means a part supply unit, embed to be shaped and first do not fire cover and the boat shape containment vessel that forms, between boat shape containment vessel and power supply board, arrange and do not fire member.In addition, description thereof is omitted with the supply unit of embodiment 1, operating means and possess structural element that the washing machine of these supply units, operating means is identical, effect etc.Therefore, below, describe supply unit 80 and operating means 70 as the feature of present embodiment in detail.

In addition; with embodiment 1 similarly; accommodate and the operation substrate 9 of protection structure operating means 70 and the boat shape containment vessel 13 of power supply board 11 (following, to be roughly recited as " containment vessel 13 ") are H shape (comprising H shape) roughly by for example cross sectional shape and at least have the identical parts formation of two recess 13a, 13b being arranged at surface and the back side.Now, power supply board 11 is installed in a recess 13b inside of containment vessel 13 and protected, and it is inner and protected that operation substrate 9 is installed in another recess 13a.

; as shown in Figure 8, the supply unit 80 of the washing machine of present embodiment at least for example, consists of the containment vessel 13 of power supply board 11, protection power source substrate 11, the encapsulation agent 24 of not firing member 41 and at least covering power supply board 11 and not firing member 41 that consists of mica member 41.

In addition, the operating means 70 of the washing machine of present embodiment consists of the containment vessel 13 that is arranged at the guidance panel 8 of the top gabarit 3 of housing, the operation substrate 9 for input operation, the power supply board 11 that forms supply unit 80 and protection power source substrate 11 and operation substrate 9.

And, as the mica member 41 that does not fire member 41, be configured between the bottom 13e and power supply board 11 of the recess 13b who has accommodated power supply board 11 in containment vessel 13, be installed on the bottom 13e of containment vessel 13.

Now, even for example also possessing good insulating properties under the more than 500 ℃ conditions of high temperature as the mica member 41 that does not fire member 41.Therefore, even in the situation that the temperature that is installed on the parts of power supply board 11 due to the carried high output such as products such as washing machines etc. rises, also can guarantee insulating properties.And, being installed on the leading part (not shown) of the parts such as microcomputer 20, connector 22 of power supply board 11 even contact with mica member 41, the insulaion resistance between leading part can not reduce yet.Its result, can prevent that the mistake of the products such as washing machine from showing, malfunction.In addition, even in the situation that the high-tension circuit being connected with source power supply of power supply board 11 breaks down and generates heat, also can guarantee insulating properties by thering is the mica member 41 of high-fire resistance.Its result, even when breaking down, also maintains high security, can guarantee high reliability.

And; even in the situation that it is outstanding from the back side of operation substrate 9, power supply board 11 to be installed on the leading part (not shown) of parts such as forming the operation substrate 9 of operating means 70 and the leading part 10a such as console switch 10 of power supply board 11, connector 22, also contact with resin bed or the mica member 41 of containment vessel 13.Therefore the resistance between, can the leading part of peventing member reduces.Its result, can realize and have the operating means 70 of the good supply unit of reliability 80 and can prevent the washing machine that malfunction, mistake show.

The preparation method of the supply unit that possesses mica member 80 of present embodiment is described below, simply.

First, for example making cross sectional shape be the roughly bottom 13e of the recess 13b side of the containment vessel 13 of H shape (comprising H shape) flatly arranges upward.

Then, the mica member 41 as not firing member 41 is configured in to the bottom 13e of containment vessel 13.

Then, under above-mentioned state, power supply board 11 is fixed to the power supply board fixed claw 16 of containment vessel 13.

Afterwards, such as having in inflow under the state of the encapsulation agent 24 such as polyurethane resin, put into high temperature groove, for example, under the condition of 60 ℃, make to encapsulate agent 24 and be dried and solidify.

And mica member 41 is installed in the bottom 13e of the recess 13b of containment vessel 13, covers for packed dose 24 together with power supply board 11 and produce supply unit 80.

Thus, even the mica member of common thin and fragile 41 is used as and does not fire member 41, also after encapsulation, with encapsulation agent 24, mica member 41 is fixed on to containment vessel 13.Therefore, prevent by mica member 41 distortion, peel off the quality badness causing and can guarantee for a long time insulating properties.

In addition, conventionally, if mica member 41 absorbs airborne moisture, insulating properties are easily deteriorated.But, by use, encapsulate agent 24 and be fixed, can interdict mica member 41 and avoid it to contact with air.Its result, prevents the quality badness of the mica member 41 that caused by moisture absorption and can realize safety and supply unit 80, the operating means 70 that reliability is high and the washing machine that possesses these supply units 80, operating means 70.

In addition, in a recess 13b of containment vessel 13, accommodate the also power supply board 11 of protection structure supply unit 80, in the recess 13a of side, accommodate overleaf and protect operation substrate 9, can produce thus the operating means 70 that possesses supply unit 80.Its result can form operating means 70 small-sizedly, and can make the integral miniaturization of the products such as washing machine.

Other structure of supply unit and the operating means of present embodiment is described with reference to Fig. 8 below.

That is to say, as shown in Figure 8, other routine supply unit 80 of present embodiment and operating means 70 are with the difference of above-mentioned supply unit 80 and operating means 70, arrange confirm window 42 (through hole) in opposed a part of position, the position with mica member 41 is set of power supply board 11.Similarly, conventionally, a part for mica member 41 is configured to also more outstanding than the end of power supply board 11 peripheries, therefore be also with above-mentioned supply unit 80 and the difference of operating means 70, the confirmation that the mica member 41 of observing the outstanding scope arranging from least one end of power supply board 11 is set is with gap 43 (through hole).Other structure is identical, and therefore description thereof is omitted.

Now, as shown in Figure 8, confirm that for example diameter d 1 of window 42 forms the gap g3 being greater than between power supply board 11 and mica member 41.Thus, when manufacturing supply unit 80, operating means 70, can make to manufacture on-the-spot illumination light and arrive the surface of mica member 41 by confirming window 42.Its result, can be via confirming that window 42 is confirmed whether to have installed mica member 41 reliably by visual.

In addition, mica member 41 is roughly white (comprising white), and containment vessel 13 is roughly black (comprising black), and encapsulation agent 24 consists of the material of transparent (comprising transparent) roughly.In addition, if be made as to the color of major general's mica member 41 and the color of containment vessel 13, with different colors, form, the combination of the color of the color of mica member 41 and containment vessel 13 is arbitrarily.

Thus, can be from confirming with gap 43, confirming that window 42 is by a part for Visual Confirmation mica member 41.Its result, forgets in the time of can preventing from for example manufacturing that installation will be installed to the mica member 41 of the bottom 13e of containment vessel 13.
