Second architectural feature of the present invention is: the 5d place, hole that dodges through in button mounting box 5 bottoms designs ring-like water retaining ribs 5b, and anti-sealing is dodged hole 5d from this and flowed into the inner design of washing machine.Like Fig. 3, shown in Figure 4; This kind mode adopts the hole 5d that dodges with button mounting box 5 bottoms to carry out dash with the ring-like water retaining ribs 5b of certain altitude; The setting of this ring-like water retaining ribs 5b height need be considered the running orbit of rotating shaft 4 in the button mounting box 5 on the one hand, prevents the too high problem that interferes with rotating shaft 4 of ring-like water retaining ribs 5b; To consider that on the other hand ring-like water retaining ribs 5b height spends the low problem that causes the dash weak effect; Through to designing certain clearance between rotating shaft 4 extreme lower positions and the ring-like water retaining ribs 5b; When guaranteeing that ring-like water retaining ribs 5b realizes the dash effect and rotating shaft 4 do not interfere; The height appropriate design of ring-like water retaining ribs 5b is 5mm～25mm, and the best is 18mm.Aspect waterproof effect, ring-like water retaining ribs 5b adopts on the one hand and will dodge the mode that hole 5d surrounds and carry out waterproof, and the water around can preventing completely gets into dodges hole 5d; Avoid current to get on the other hand from water retaining ribs 2a top; Through cooperating between control seat 2 and the button 1; Let water flow in the button 1, and water can't directly be got in the button 1, flow into but pasting button 1 two sides through the hierarchic structure of button 1 mating part from the gap (being that water is around button) between control seat 2 and the button 1; Thereby guarantee that water can't get into from water retaining ribs 5b top, plays waterproof action.Other waterproof type; As will dodge 5d place, hole realizes waterproof with the seal sealing function; But this method lacks feasibility, that be since button 1 in the process of operation, pull-rod spring 7 is when moving up and down; Also have the swing of horizontal direction, do not have the seal of similar this kind mode in the market.The shape of ring-like water retaining ribs 5b can be carried out suitable adjustment according to the difference of dodging hole 5d shape, and this structure also having greater advantage aspect mouldability, the economy, and application is wider.
The 3rd architectural feature of the present invention is: design gutter 5c below pilot hole 5e.In water gets into button 1, can't be when dodging hole 5d and flow out, water can flow to pilot hole 5e, and in orifice flow was gone into gutter 5c, through the guiding of gutter 5c, water was just along gutter 5c outflow button 1.In design, what time followingly need to consider: the one, the diversion direction of gutter 5c.Because some is installed in electronic devices and components and puts on the angle 6,, can consider to gate 8 sides, casing 9 sides and the 2 side diversions of front-end control seat so can't consider water to be drawn from putting angle 6; As considering that to gate 8 side diversions water finally can paste control seat 2 places of gate 8 sides toward dirty, the parts such as safety switch 10, motor and lead-in wire of can flowing through adopt guiding mechanism to locate channeling conduct at this, can't guarantee that also electronic unit does not get wet, and do not have a security; As consider directly to guide into casing 9 sides, and consider to also have a bigger segment distance between gutter 5c and the casing 9, can't be directly to casing 9 side drainings; Water directly flows out from gutter 5c; From control seat 2 with put between the angle 6 space toward dirty, owing to being unsettled falling, so dirty situation can't be controlled through structure; Have certain probability to drip to gate lock 3 and lead-in wire place, waterproof effect is not good.The 2 side diversions of forward end control seat can let current along control seat 2 medial surfaces toward dirty, current are had control preferably, and the zone of flowing through do not relate to gate lock 3 and lead-in wire etc. parts, security is better.The 2nd, the angle of inclination of gutter 5c.The diversion effect of gutter 5c promptly will be considered in the angle of inclination; Consider the size of overall dimensions again, too little like the diversion angle of inclination, current have one section backflow at the outer bottom of gutter 5c; Thereby can't realize leading water to the purpose of control seat 2; And water is back to puts angle 6, influence gate lock 3 and lead-in wire, potential safety hazard is arranged; Too big like gutter 5c angle of inclination, can make overall dimensions become big, there is the risk of interfering simultaneously with gate 8 sides control seat 2; All influential to mouldability assembling aspect; So on the angle design of gutter 5c, set angle of the present invention is more reasonable between 10 °～45 °, the best is 27 °.The present invention adopts the design of gutter 5c effectively water to be discharged, and also has greater advantage aspect mouldability, economy, the practicality.
The 4th architectural feature of the present invention is: control seat 2 places corresponding below button installing plate 5 bottoms design water guide rib 2a.This water guide rib 2a is perpendicular to control seat 2 medial surfaces; And to casing 9 tilt; This structure Design is to control seat 2 casings 9 sides in order to reach from the water that button 1 is derived directly all to guide to from the water that gets between button 1 and the control seat 2, guarantees the safety of diversion route, and it is more thorough to let water discharge.This structure Design mainly is to consider between control seat 2 and the gutter 5c to have gap (preventing that the deviation of processing from causing the problem of interfering) in the design, makes gutter 5c can't whole water be guided to control seat 2 places, and wherein a part of water has one section backflow; Between control seat 2 and the button 1 space is arranged, some water is directly past dirty from the space, and dripping extremely, control seat 2 possibly splash the electronic devices and components place.Water guide rib 2a is set on control seat 2 can catches the water of part backflow and the water that the gap flows into, guarantee that water all flow on the control seat 2.Aspect the water guide effect, because glassware for drinking water has certain force of strain, so the angle that most water can paste between water guide rib 2a and the control seat 2 is past dirty; Wherein fraction reflux the water that gets off along water guide rib 2a upper end toward dirty, few part possibly flow out water guide rib 2a, but because the backflow effect of current; Weep particularly; The water backflow effeet of low flow velocity can be obvious more, therefore can or not influence gate and lock 3 parts such as grade along the water guide rib lower surface to the place's diffluence of control seat.To this, also requirement to some extent aspect size, position and the inclination angle of water guide rib 2a, the assembling of too high influence of water guide rib 2a position height and button 1 is crossed the low dash effect that influences; 2 moulding of the too wide influence of water guide rib 2a width control seat, too narrow do not have a dash effect, stretches out 15mm～25mm foremost with gutter 5c and be advisable, and the best is 20mm; The inclination angle is too little too greatly also can to influence the dash effect, and the present invention sets the angle of inclination between 20 °～40 °, and the best is 30 °.
The 5th architectural feature of the present invention is: be provided with two confining tendon 5a in the button mounting box 5, respectively in ring-like water retaining ribs 5b and arranged on left and right sides, prevent to be splashed into the structure that discharge influences waterproof effect when big in this way.Consider that the gap of button 1 two sides and button installing plate 5 was bigger when current got in the button installing plate 5 around the button 1, current entering flow maybe be bigger, is splashed in the ring-like water retaining ribs 5b thereby cause current in button installing plate 5, to be run helter-skelter.The design of confining tendon 5a can intercept the current of running helter-skelter, and prevents that current are splashed into ring-like water retaining ribs 5b, has improved waterproof effect of the present invention under the extreme case greatly.
In sum; Adopt structure of the present invention, can the water that be splashed in the button be derived washing machine, the waterproof requirement of push button gate switch when satisfying washing machine and being positioned over balcony, toilet; Protection washing machine internal electric spare; Like gate lock, connector and lead-in wire etc., prevent these parts ponding, ensure the security of operation of washing machine.
