Concrete meaning in the present invention.
As shown in Figure 1 to Figure 3, operation key asembly of the invention includes collecting tank 1, diversion trench 2 and operation key 3, is collected
1 encircling operation key 3 of slot is arranged, for collecting the water on operation key 3；Diversion trench 2 is connected to collecting tank 1, for exporting collecting tank 1
Interior water.
The water on operation key 3 is collected by collecting tank 1, prevents water straight from the gap between operation key 3 and control panel
It connects and penetrates on pcb board, it is therefore prevented that pcb board damages, and the water flowed in collecting tank 1 is directly exported control in time by guiding gutter
Outside panel processed, the water for avoiding discharge is flowed into from the gap between control panel and operation key 3 on pcb board, and diversion trench 2 is also
It prevents the water in collecting tank 1 that overflow occurs, penetrates on pcb board, improve from the gap between operation key 3 and control panel
3 waterproof effect of operation key, ensure that the Electrical Safety of washing machine.
As shown in figures 1 and 3, in a kind of preferable embodiment, the bottom of the bottom of diversion trench 2 relative to collecting tank 1
Plane where portion is obliquely installed, it is preferable that the bottom of diversion trench 2 is tilted to the direction at the top far from operation key 3, diversion trench
Angle between 2 bottom and the bottom of collecting tank 1 is 10 °~80 °.Since the control panel of roller washing machine is to be vertically arranged
, when the water in collecting tank 1 is directed downwardly toward safety zone by water by diversion trench 2, the fall trajectory of water and it is obliquely installed
Angle α is formed between the bottom of diversion trench 2, α is 10 °~80 ° so that during falling under water, water is led with what is be obliquely installed
Spacing between the bottom of chute 2 vertically gradually increases, so that the water of discharge is detached with control panel, avoids
The water of discharge flows into pcb board from the gap between control panel and operation key 3, improves the water resistance of operation key 3.Moreover,
The bottom for the diversion trench 2 being obliquely installed can also block the gap between control panel and operation key 3, avoid the water of discharge
Pcb board is flowed into from the gap between control panel and operation key 3, further improves the water resistance of operation key 3.
Therefore, by repeatedly designing and testing, it is by the angle between the bottom of diversion trench 2 and the bottom of collecting tank 1
30 °~60 ° are best angle range, i.e., angle α is 30 ° between the fall trajectory of water and the bottom for the diversion trench 2 being obliquely installed
~60 °, therefore use above-mentioned angle as the angle between the bottom and the bottom of collecting tank 1 of diversion trench 2.Preferably, diversion trench 2
Bottom and the bottom of collecting tank 1 between angle be 45 °, the water for not only improving discharge is detached with control panel, and is conducive to
Gap between control panel and operation key 3 is blocked.
As shown in figure 3, in a kind of preferable embodiment, the width of diversion trench 2 is from the outlet end of diversion trench 2 to water conservancy diversion
The position that slot 2 is combined with collecting tank 1 gradually increases so that the flaring structure that diversion trench 2 shows, this structure of diversion trench 2
Design can in time export the water in collecting tank 1, and the water being exported is pooled to designated position by diversion trench 2, be convenient for
The discharge of water.
In said structure, at least one side wall of diversion trench 2 is arc.Preferably, the one side wall of diversion trench 2 is arc
Shape so that the water in collecting tank 1 can be flowed into along the track of arc in diversion trench 2, reduced the inflow of the water in collecting tank 1 and led
Resistance in chute 2；Another side wall of diversion trench 2 is vertically arranged so that the water in collecting tank 1 is under gravity along perpendicular
Histogram is to flowing directly into diversion trench 2, convenient for exporting the water in collecting tank 1.
Overflow phenomena occurs for the water collected in order to prevent in diversion trench 2, and the height of the side wall of diversion trench 2 is by diversion trench 2
The position that is combined to diversion trench 2 with collecting tank 1 of outlet end be gradually reduced, the height at the position that diversion trench 2 is combined with collecting tank 1
It is identical as the height of collecting tank 1.Preferably, the plane where the top of the side wall of diversion trench 2, the top with the side wall of collecting tank 1
Co-planar where portion.
As depicted in figs. 1 and 2, in a kind of preferable embodiment, operation key asembly further includes being arranged on collecting tank 1
For collecting tank 1 to be installed to the fixture block 11 on control panel, can be arranged on the control panel and 11 matched card of fixture block
Slot, fixture block 11 are sticked in card slot, can prevent operation key 3 from being rotated around the rotation axis of operation key 3, ensure that operation key 3 is solid
Fixed stability on the control panel, and therefore improve efficiency of assembling.
Preferably, the quantity of fixture block 11 is two, and two fixture blocks 11 are symmetricly set on receipts relative to the symmetry axis of collecting tank 1
On the side wall for collecting slot 1 so that stress balance during operation key 3 is connected together with control panel, to ensure that operation key 3
It can steadily be stuck in control panel.
In said structure, the top of fixture block 11 is equipped with groove 111.In the process that operation key 3 is assembled to control panel
In, finger is stuck in groove 111, and fixture block 11 is sticked in card slot, and operation is more convenient, quick, and accuracy is high.
It will be appreciated to those of skill in the art that the quantity for the fixture block 11 being arranged on above-mentioned collecting tank 1 is not limited to two
It is a, can change its quantity according to actual conditions, but no matter the quantity increase of fixture block 11 how much, by all fixture blocks 11 along receipts
The circumferential spaced set for collecting slot 1 ensure that operation key 3 fixes stability on the control panel.
As shown in Figure 1, in a kind of preferable embodiment, collecting tank 1 is the slot of the part-toroidal around operation key 3,
The slot of part-toroidal is located at the lower section of operation key, and the slot of part-toroidal is connected in its opening portion with diversion trench, the side of collecting tank 1
Wall it is highly consistent, the opening being connected to diversion trench 2 is offered on collecting tank 1.
Wherein, collecting tank 1, diversion trench 2 and operation key 3 are integrally formed, using integrally formed structure convenient for mold
It designs and produces.
It should be further noted that collecting tank 1 is used not only for collecting the water on operation key 3, and can be used in
Collect the water on 3 periphery of operation key.
In said structure, operation key 3 includes any components with operating function such as button, membrane keyboard, knob.
In addition to aforesaid operations key asembly, the present invention also provides a kind of washing machine, which includes aforesaid operations key
Component improves the water resistance of operation key 3 by aforesaid operations key asembly, avoid water from operation key 3 and control panel it
Between gap directly penetrate on pcb board, it is therefore prevented that pcb board damage, ensure that the Electrical Safety of washing machine.
So far, it has been combined preferred embodiment shown in the drawings and describes technical scheme of the present invention, still, this field
Technical staff is it is easily understood that protection scope of the present invention is expressly not limited to these specific implementation modes.Without departing from this
Under the premise of the principle of invention, those skilled in the art can make the relevant technologies feature equivalent change or replacement, these
Technical solution after change or replacement is fallen within protection scope of the present invention.
