The operation principle of above-mentioned push button gate switch is: hand applies an active force on button 1, and an angle of button 1 rotation, drive rotating shaft 4 rotations, thereby drives pull-rod spring 7 driving machine door lock 3 work, and gate 8 is opened with regard to corresponding; After active force is cancelled, gate lock 3 is given 7 one resiliencys of pull-rod spring, thereby drives rotating shaft 4 convolutions, and the elastic force of little spring is returned to initial position by button 1 simultaneously.Push button gate switch is arranged on putting on angle 6 of casing 9, above Coverage Control seat 2, these parts actings in conjunction have just realized the opening door operation of washing machine gate 8.
Its waterproof principle is: water is splashed into from the gap between button 1 and button installing plate 5, acting in conjunction by confining tendon 5a and water retaining ribs 5b prevents that current from entering and dodges hole 5d (as arrow indication in Fig. 3), and water is drawn from pilot hole, the water guide rib 2a that guides to control block 2 through gutter 5c goes up (arrow indication in as Fig. 3), current, along control block 2 medial surfaces toward dirty (as arrow indication in Fig. 3), flow to washing machine pedestal and discharge washing machine.Waterproof construction does not in this way relate to the problems such as machining accuracy and tolerance fit, and processing and installation are on water-proof function substantially without impact, and waterproof effect is stable simultaneously; Mode by guiding realizes good water-proof effect, and draining is more thorough.
One of the present invention is characterised in that: by button 1 and control block 2 places, designing the water-proof function that drawing water structures are realized washing machine, compare the waterproofing design of other modes, the present invention has the characteristics such as good water-proof effect, economic and practical are good, novel structure, good moldability.The waterproof thinking of other modes has: 1. at gate lock place design waterproof construction, as to gate lock 3, designed waterproof jackets etc., these modes can realize certain water-proof function, but because gate lock 3 need to be connected with connector with pull-rod spring 7, bad at these junction waterproof effects, and can't avoid the water entered to flow to the washing machine internal miscellaneous part, complex structure, cost is high; 2. button is carried out to the sealing design, can key meet the basic function of button when being sealing, as in the interior employing Seal Design of button mounting box 5, matching relationship between more difficult control pull-rod spring 7 and button mounting box 5, also can't process the problem of how ponding being discharged, and more difficult between button 1 and control block 2, carrying out Seal Design, this design is extremely complicated, mouldability and less economical; 3. at pull-rod spring 7 middle part design dash drawing water structures, can the whether feasible key of the method be realize intercepting current toward current downflow, but due to button 1 the operation process in, pull-rod spring 7 is when moving up and down, have the swing of horizontal direction, the water-retaining structure of design need to move and will guarantee the dash effect together with pull-rod spring 7, thereby to require it be flexible material or movable part, waterproof effect can descend because it moves, complex structure, cost is high, can't meet actual requirement.To sum up several imaginations have comprised multiple mentality of designing; but waterproof effect is all undesirable; structure is more complicated; cost is higher; and, at button 1 and control block 2 place's design drawing water structures, be equivalent to intercept entering of current on source, not only protected the safety of gate lock 3; and guaranteeing that the current that enter from button 1 can't enter other safety components such as lead-in wire, waterproof effect is very thorough.
Second architectural feature of the present invention is: design ring-like water retaining ribs 5b by the 5d place, hole that dodges in button mounting box 5 bottoms, anti-sealing dodges from this design that hole 5d flows into washing machine internal.As shown in Figure 3, Figure 4, this kind of mode adopts carries out dash by the hole 5d that dodges of button mounting box 5 bottoms 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 the interior rotating shaft 4 of button mounting box 5 on the one hand, prevents the too high problem interfered with rotating shaft 4 of ring-like water retaining ribs 5b; To consider on the other hand the highly too low problem that causes the dash weak effect of ring-like water retaining ribs 5b, by the gap certain to design between rotating shaft 4 extreme lower positions and 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 that can prevent thoroughly surrounding enters dodges hole 5d; Avoid on the other hand current to enter from water retaining ribs 2a top, by coordinating between control block 2 and button 1, allow water flow in button 1 from the gap between control block 2 and button 1 (being that water is around button), and the hierarchic structure by button 1 mating part allows water can't directly enter in button 1, but pasting button 1 two sides, flow into, thereby guarantee that water can't enter from water retaining ribs 5b top, plays waterproof action.Other waterproof type, realize the function of waterproof with the seal sealing as dodged 5d place, hole, but the method lacks feasibility, that be due to button 1 the operation process in, pull-rod spring 7 is when moving up and down, also have the swing of horizontal direction, there is no in the market the seal of similar this kind of mode.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, economy, and application is wider.
The 3rd architectural feature of the present invention is: design gutter 5c below pilot hole 5e.In water enters button 1, can't be when dodging hole 5d and flow out, water can flow to pilot hole 5e, and, in hole flows into gutter 5c, by the guiding of gutter 5c, water is just along gutter 5c outflow button 1.In design, what time followingly need to consider: the one, the diversion direction of gutter 5c.Due to electronic devices and components, some is arranged on and puts on angle 6, therefore can't consider from putting angle 6, water to be drawn, can consider to gate 8 sides, casing 9 sides and the 2 side diversions of front-end control seat; As considered to gate 8 side diversions, water finally can paste control block 2 places of gate 8 sides toward dirty, and the parts such as safety switch 10, motor and lead-in wire of can flowing through adopt guiding mechanism to guide at this place, also can't guarantee that electronic unit does not get wet, and does not have a security; Directly guide casing 9 sides into as considered, consider between gutter 5c and casing 9 and also have a larger segment distance, can't be directly to casing 9 side drainings, water directly flows out from gutter 5c, from control block 2 and put between angle 6 space toward dirty, owing to being unsettled falling, therefore dirty situation can't be controlled by structure, have certain probability to drop to gate lock 3 and lead-in wire place, waterproof effect is not good.The 2 side diversions of forward end control block can allow current along control block 2 medial surfaces toward dirty, current are had preferably and control, 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 will be considered in angle of inclination, consider again the size of overall dimensions, as too little as 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 block 2, and water is back to and puts angle 6, affect gate lock 3 and lead-in wire, potential safety hazard is arranged; As too large as gutter 5c angle of inclination, can make overall dimensions become large, there is the risk of interfering with gate 8 side control blocks 2 simultaneously, all influential to mouldability assembling aspect, therefore, 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, practicality.
The 4th architectural feature of the present invention is: control block 2 places corresponding below button installing plate 5 bottoms design water guide rib 2a.This water guide rib 2a is perpendicular to control block 2 medial surfaces, and roll tiltedly to casing 9, the design of this structure to be the water in order deriving from button 1 and directly from the water entered between button 1 and control block 2, all to guide to control block 2 casing 9 sides, guarantees the safety of diversion route, allows water discharge more thorough.The design of this structure is mainly to consider between control block 2 and gutter 5c to have gap (deviation that prevents processing causes the problem of interfering) in design, make gutter 5c whole water can't be guided to control block 2 places, wherein a part of water has one section backflow; Between control block 2 and button 1, space is arranged, some water directly, from space toward dirty, drops to control block 2 and may splash the electronic devices and components place.Water guide rib 2a is set on control block 2 and can catches the water of part backflow and the water that gap flows into, guarantee that water all flow on control block 2.Aspect the water guide effect, because glassware for drinking water has certain tension force, therefore the angle that most water can paste between water guide rib 2a and control block 2 is past dirty, wherein fraction reflux the water that gets off along water guide rib 2a upper end toward dirty, few part may flow out water guide rib 2a, but due to the backflow effect of current, weep particularly, the water backflow effeet of low flow velocity can be more obvious, therefore can, along the water guide rib lower surface to the diffluence of control block place, can not affect gate and lock 3 parts such as grade.To this, also requirement to some extent aspect size, position and the inclination angle of water guide rib 2a, the assembling of the too high impact of water guide rib 2a position height and button 1, the too low dash effect that affects; Water guide rib 2a width is too wide affects control block 2 moulding, and too narrow do not have a dash effect, stretches out foremost 15mm～25mm with gutter 5c and be advisable, and the best is 20mm; Inclination angle is too little too greatly also can affect the dash effect, and the present invention sets 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 button mounting box 5, respectively in ring-like water retaining ribs 5b arranged on left and right sides, prevent from this way being splashed into the structure that discharge affects waterproof effect when large.Consider that current are from entering button installing plate 5 around button 1 when interior, the gap of button 1 two sides and button installing plate 5 is larger, and current enter flow may be larger, thereby cause current to run helter-skelter and be splashed in ring-like water retaining ribs 5b in button installing plate 5.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 greatly improved waterproof effect of the present invention under extreme case.
In sum; adopt structure of the present invention; the water be splashed in button can be derived to washing machine; the waterproof requirement of push button gate switch when meeting washing machine and being positioned over balcony, toilet; protection washing machine internal electricity piece; as gate lock, connector and lead-in wire etc., prevent these parts ponding, ensure the security of operation of washing machine.
