2 water inlets, namely towards injecting water in cabinet 2, and electric flowing component 5 can give cabinet 2 to be discharged by Electronic control, also i.e. by case
The water export of 2 the inside of body.Electronic water inlet component 4 be connected to by pipeline with water source, electric flowing component 5 pass through other pipeline and
External world's connection.
Above-mentioned liquid level sensor 1 is mounted at the case mouth of cabinet 2 and the first conductive rod 13, the second conductive rod 14, third are led
Torch 15 and the 4th conductive rod 16 protrude into cabinet 2 vertically, the first conductive rod 13, the second conductive rod 14, third conductive rod 15
The different depth of cabinet 2 can be extended to respectively with the bottom end of the 4th conductive rod 16.
Above controller 3 and above-mentioned electronic water inlet component 4, electric flowing component 5, the first circuit of liquid level sensor 1, the
Two circuits and tertiary circuit are electrically connected according to the first circuit.It is electronic that the on-off of second circuit and tertiary circuit opens control
The working condition of water inlet component 4 and electric flowing component 5.
Specifically:
When the liquid level in cabinet 2 is lower than the bottom end of above-mentioned 4th conductive rod 16, above-mentioned first circuit, second circuit and the
Three-circuit does not turn on, intakes at this point, controller 3 controls electronic water inlet component 4 to cabinet 2；
Contacted when the liquid level in cabinet 2 rises to the bottom end of the 4th conductive rod 16, at this time the first circuit, second circuit and
Tertiary circuit does not turn on, and controller 3, which controls electronic water inlet component 4, to be continued to intake to cabinet 6.
When the liquid level in cabinet 2, which rises to, to be contacted with the bottom end of third conductive rod 15, at this time tertiary circuit conducting and first
Circuit and second circuit are still in off-state, and controller 3 controls electronic water inlet component 4 and keeps the state intake to cabinet 2；
When the liquid level in cabinet 2, which rises to, to be contacted with the bottom end of the second conductive rod 14, tertiary circuit and second circuit at this time
It is both turned on and the first circuit is in an off state, controller 3 then closes electronic water inlet component 4, is allowed to stop intaking to cabinet 2；
If the failure of liquid level sensor 1 leads to fluid level contacts 14 bottom end of the second conductive rod, second circuit portion is still

This has been commonly available use in the prior art, and when circuit breaks down, the controller 3 being attached thereto drives warning device
9 alarms, this is also to use very universal technology in the prior art, therefore no longer repeated in detail it herein.Certainly, such as
If electronic water inlet component 4 cannot start work, above controller 3 also will driving warning device alarm.
When the water in cabinet 2 with use and after decline, it will repeat above-mentioned movement, it is automatic to cabinet 2 to realize
The function of liquid level is controlled, but also can be arranged inside controller periodically, gives the water supply water outlet of cabinet 2 with timing, fixed time.When
So, above-mentioned electric flowing component 4 will work always after starting, until liquid level be reduced to 15 bottom end of third conductive rod with
It is lower just to stop namely when the first circuit, second circuit and tertiary circuit are conducting, controller 3 drives electric flowing group
Part 5 stops working, and electronic water inlet component 4 will start to start work and supply water to cabinet 2 at this time.
Water tank 2 provided in this embodiment carries out cabinet 2 due to using the cooperation of above-mentioned liquid level sensor 1 and controller 3
The control of interior liquid level, control accuracy is higher, and since the stability in use of above-mentioned liquid level sensor 1 is strong, so the water tank 2
Long service life, be less prone to the situation of liquid level exception in cabinet 2.
Embodiment 4:
More excellent embodiment of the present embodiment as embodiment 3 is also provided in the cabinet 2 of water tank provided in this embodiment
Overflow groove 6, the vertical range between 2 bottom of notch and cabinet of the overflow groove 6 is less than the depth of cabinet 2 and to be greater than first conductive
The distance between 13 bottom end of stick and 2 bottom of cabinet, for example, by the vertical range ratio between 2 bottom of the notch of overflow groove 6 and cabinet
Make z, the depth of cabinet 2 is compared to x, and the distance between 13 bottom end of the first conductive rod and 2 bottom of cabinet are compared to y, y < z < x.This overflows
Gap 61 is equipped at the notch of sink 6, gap 61 is connected to 2 external space of cabinet.
When the liquid level in cabinet 2 rise to contacted with the bottom end of the first conductive rod 13 when, above-mentioned tertiary circuit cannot be connected,
Perhaps controller 3 breaks down and electric flowing component 5 cannot be driven to start work or the failure of electric flowing component 5
And cannot work, the liquid level in cabinet 2 continues to rise at this time, until rising to the notch of overflow groove 6, the water in cabinet 2 will
Overflow groove 6 can be flowed into and flowed away from gap 61, most preferably, pipeline is also connected at the gap 61, the water of outflow is drawn
Somewhere is flow to be collected.
Using this kind of structure, the cooperation of overflow groove 6 and above-mentioned liquid level sensor 1 and controller 3 just can guarantee this implementation
The case where cabinet 2 that example provides is not in spilling water at case mouth certainly.
It is worth noting that, work cannot be started when either electric flowing component 5 cannot be connected in above-mentioned tertiary circuit, on
Stating controller 3 can drive warning device 9 to alarm.
