Description
Technical field
The present invention relates to kitchen appliance technical fields, specifically be a kind of excess flow protection device and its water tank type fruit-vegetable clear
Washing machine.
Background technique
Sink type fruit vegetable cleaner is that the function of automatic cleaning fruits and vegetables is integrated on sink, has automatic cleaning fruits and vegetables
Function, structure generally comprises the groove body being mounted on kitchen countertop, and the top of the groove body has opening, in there is washing
Chamber, bottom are connected to by drainpipe；The groove body generally comprises rinse bath and fruits and vegetables rinse bath, sets in the fruits and vegetables rinse bath
There is spray equipment, for carrying out hydroblasting to fruits and vegetables, the bottom of fruits and vegetables rinse bath is equipped with supersonic generator, for in water
Emit ultrasonic wave, cleans fruits and vegetables using ultrasonic wave；The bottom of fruits and vegetables rinse bath is additionally provided with electronic control unit and pump motor, in order to
Preventing electronic control unit is considered touching and the safety of product, is generally equipped with bottom case in the bottom of fruits and vegetables rinse bath, the bottom case
Electronic control unit, pump motor, supersonic generator etc. are blocked inside it, avoid artificially being touched, is caused dangerous.Bottom case
Being arranged makes the aesthetics of product and safety be greatly improved, still, and if overflow is too late or overflow mechanism when water inlet
Leak in the case where failure, the water to leak down can collect in the inside of bottom case, if the water collected excludes or too late not in time
When cut off inlet valve, it is likely that so that electronic control unit in bottom case is intake and failure or occur Danger Electric shock risk.
The bottom of its bottom case of the sink type fruit vegetable cleaner of the prior art is provided with excess flow protection device, overflow protection dress
Setting is that microswitch will be fixed in the inner bottom wall of bottom case, and the contact of microswitch is then touched using the buoyancy of float,
Then microswitch cutting inlet unit stops water inlet；But its installation of the excess flow protection device of the prior art is very inconvenient and micro-
The fixed structure of dynamic switch is more complicated, and using effect is poor.
Summary of the invention
The technical problem to be solved by the present invention is to, overcome the defect of the above prior art, provide it is a kind of installation, disassembly side
Just, and high sensitivity, microswitch movement can be triggered in time to cut off the excess flow protection device of inlet unit.
The technical solution of the invention is as follows, and provide a kind of excess flow protection device having following structure: it includes
Bottom cover, inner bottom wall is equipped with recessed groove, for assembling the water to leak down；
Bracket is detachably connected in groove, and forms accommodation space between bracket and the inner bottom wall of groove；
Microswitch is detachably connected on bracket, and the contact of microswitch is arranged straight down, the fine motion
Switch is electrically connected by conducting wire and electronic control unit；
Float assembly is movably connected in accommodation space, and float assembly in accommodation space have move up and down between
Gap touches the contact of microswitch after float assembly rises certain displacement under the buoyancy of water, keeps microswitch cutting automatically controlled
The circuit of unit.
After using the above structure, excess flow protection device of the present invention compared with prior art, has the advantage that the overflow is protected
The inner bottom wall of the bottom cover of protection unit is equipped with recessed groove, which is used for the water that leaks down of rapid aggregation, when assembling in groove
When having the water to leak down, float assembly floats under the action of water, thus make the contact of the upper end touching microswitch of float assembly,
Make the circuit of microswitch cutting electronic control unit, so that inlet unit be made to stop water inlet, realizes overflow protection.The bottom cover inner bottom wall
The setting of upper groove allows the water to rapid aggregation, so that the speed for making float assembly float is fast, can touch microswitch and cut in time
Deenergizing, high sensitivity；Furthermore water that is microswitch is rack-mount, avoiding microswitch contact from leaking down, safety
Higher, the long service life of property.
