Abstract

The invention provides a waterproof switch and a refrigerator. The waterproof switch includes a casing. Electrified parts are arranged at an opening at the lower part in the casing. A key or a warping plate is arranged at an opening at the upper part in the casing. A partition wall which is in seal connection with the periphery in the casing is arranged between the key or the warping plate and the electrified parts. Through holes are arranged in the partition wall. A power transmission part which passes through the through holes in the partition wall is arranged between the key or the warping plate and the electrified parts. The invention also provides a refrigerator which adopts the waterproof switch. The waterproof switch prevents direct contact of the button or the key and the electrified parts and encloses the electrified parts in a relatively airtight space so that water does not flow to the electrified parts via the button or the key when flowing through the switch and thus the waterproof performance of the switch is improved significantly.

Description

Water proof switch and refrigerator
 
Technical field
The invention belongs to electric switch technical field, specifically, relate to a kind of water proof switch and adopt the refrigerator of this water proof switch.
Background technology
At present, switch used on refrigerator is mainly seesaw push button and button structure, seesaw or button are contacts with live part, button and button being removed rear whole live part will be completely out exposed, and follow periphery to be direct conducting by button or the gap between button and housing, switch is installed to after on casing by control panel, do trickle experiment have current through switch time, water can be entered along button or the slit flow between button and switch case, arrive live part, just there will be punch-through when doing withstand voltage, make experiment defective; If in use procedure, have water to flow into button or button, the conductivity due to water make button or button charged, the danger of getting an electric shock can be there is when people contacts.
Summary of the invention
The invention provides a kind of water proof switch and adopt the refrigerator of this water proof switch, the waterproof problem of switch can be solved, avoid button or button contacts with the direct of live part, live part is enclosed in a relatively airtight space, can not flow on live part via button or button when current are through switch, substantially increase the water resistance of switch.
For solving the problems of the technologies described above, the present invention is achieved by the following technical solutions:
On the one hand, the invention provides a kind of water proof switch, comprise housing, lower openings place in housing arranges live part, upper opening place in housing arranges button or seesaw, the partition that is connected with enclosure interior peripheral sealing is set at described button or between seesaw with live part, described partition arranges through hole, at button or the force transferring part that arranges between seesaw and live part through through hole on partition.
Water proof switch described above, described force transferring part at least comprises steel tape, and this steel tape one end is point, and the other end has two supporting legs.
Water proof switch described above, through hole on described partition comprises two, described live part comprises three live terminal, and wherein a live terminal is provided with elastic copper sheet, and two supporting legs of described steel tape to penetrate in two through holes and are connected with elastic copper sheet one end of bottom.
Water proof switch described above, the through hole of described partition is provided with the guide channel protruding from partition two surface, two supporting legs of described steel tape are placed in guide channel and also can move up and down, guide channel makes steel tape in motion process steadily, and cuts off guide channel above and can be entered the live part place of enclosure interior by through hole by further anti-sealing.
Water proof switch described above, described partition, guide channel are all one-body molded with housing.
Water proof switch described above, described steel tape adopts PVC(polyvinyl chloride), the insulating material such as nylon makes, making very thin, whole steel tape is not only light but also thin.
Water proof switch described above, described partition upper surface is provided with indicator light.
Water proof switch described above, when the upper opening place in housing arranges button, this water proof switch is key switch, described force transferring part also comprises power transmission spring, and power transmission spring one end is connected with button, and the other end is sleeved on the point of steel tape, when a key is pressed, power transmission spring drives steel tape to move downward, and makes elastic copper sheet connect another live terminal, and switch is energized;
When again pushing button, power transmission spring can drive steel tape to move upward, and makes elastic copper sheet leave live terminal, switch circuit breaking.
Specifically, in button, be provided with extension spring, both sides, button bottom are provided with return spring, extension spring connects downward steel wire, steel wire lower end has hook portion, is provided with gathering sill, when button moves downward at the shell place of indicator light, the hook portion of steel wire lower end slips in gathering sill and is stuck, thus button can not be rebounded, while button moves downward, power transmission spring drives steel tape to move downward, make elastic copper sheet connect another live terminal, switch is energized.When again pushing button, the hook portion of steel wire lower end departs from gathering sill, under the effect of the return spring of button two bottom sides, button resets, and button both sides are stuck on housing, and the spring of power transmission simultaneously drives steel tape to move upward, elastic copper sheet is made to leave another live terminal, switch circuit breaking.
Water proof switch described above, when the upper opening place in housing arranges seesaw, this water proof switch is seesaw push-button switch, seesaw top is provided with button, seesaw both sides are hinged on housing, and seesaw is the arcuate structure that two ends tilt, and the point of steel tape is connected with one end of seesaw.
Specifically, spring and cylinder are set between button and seesaw, spring housing is contained in the upper end of cylinder, cylinder lower end withstands on the arc groove position of seesaw, and when pressing the button one end, cylinder lower end can connect steel tape one end to seesaw and slide, seesaw is connected one end pressure of steel tape, drive steel tape moves downward, and makes elastic copper sheet connect another live terminal, and switch is energized;
When pressing the button the other end, can slide to seesaw away from steel tape one end in cylinder lower end, seesaw one end away from steel tape can be depressed, thus seesaw pulls steel tape to move upward, and makes elastic copper sheet leave another live terminal, switch circuit breaking.
On the other hand, the present invention also provides a kind of refrigerator, adopts above-mentioned water proof switch.
The power on/off of water proof switch of the present invention, it is the Stroke Control by a middle steel tape (insulation), steel tape is by guide channel and body contact, gap between steel tape and guide channel is very little, about 0.2mm, under the surface tension effects of water, current through time can not flow to live part and get on.
Button or button and live part are directly separated with the partition of base closed, controlled by a steel tape, when water is entered along button or the slit flow between button and switch case, do not reach on live part, thus trickle experiment can be passed through smoothly, solve refrigerator trickle and test defective phenomenon.
Water proof switch of the present invention, it is the partition that base closed is set in housing, then through hole is set on partition, at button or arrange through cutting off the force transferring part of through hole between seesaw and live part, the power on/off of switch is by force transferring part transmission, because the gap of force transferring part and through hole is very little, when water is entered along button or the slit flow between button and switch case, under the tension force effect of water, current through time can not be flow to live part by the gap between force transferring part and through hole and get on, do not reach on live part, thus trickle experiment can be passed through smoothly, solve refrigerator trickle and test defective phenomenon.
