Detailed description of the invention
Below in conjunction with accompanying drawing, carry out clear, complete description to the technical solution of the utility model, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on embodiment of the present utility model, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to protection domain of the present utility model.
Embodiment one:
With reference to accompanying drawing 1, be arranged on the first water level probe 3 of tank or water tank sidewall bottom and be arranged on the second water level probe 2 of tank or water tank side wall upper part, second water level probe 2 is connected to control unit 5 by gate-controlled switch 4, control unit 5 is MCU preferably, gate-controlled switch 4 is relay preferably, gate-controlled switch 4 is connected with the second water level probe 2 control realized gate-controlled switch 4 break-make, and the second water level probe 2 is connected to control unit 5, and the output of control unit 5 is connected with the first controllable water valve 1.In fill phase, control unit 5 controls gate-controlled switch 4 and closes, when the water level of water level lower than the second water level probe 2, control the first controllable water valve 1 and intake in cavity, along with constantly entering of water, water level raises gradually, when water level reaches the height of the second water level probe 2, the first water level probe and the second water level probe are formed loop by water short circuit conducting, and the second water level probe 2 detects water level signal, control unit 5 controls controllable water valve 1 and closes, and stops water inlet.When water level detecting is complete, control unit 5 controls gate-controlled switch and opens, thus the second water level probe is disconnected.Because water level probe is made up of metal material usually, some metals are energized for a long time electrolysis in water, can turn black because electrolysis time is long or conductance decline, water degradation and water level detecting is caused to lose efficacy, by the gate-controlled switch 4 arranged, efficiently avoid water level probe and link water route for a long time and produce electrolysis.
Embodiment two:
With reference to accompanying drawing 2,3, embodiment two is with the difference of embodiment one: also comprise the second controllable water valve 7 and the 3rd water level probe 6,3rd water level probe 6 setting position is higher than the first water level probe 3 and the second water level probe 2, second water level probe 2 is connected by gate-controlled switch 4 control unit 5 with the 3rd water level probe 6, gate-controlled switch 4 is single-pole double-throw relay, and control unit 5 connects the second controllable water valve 7 and carries out draining.In fill phase, single-pole double-throw relay connects the second water level probe 2, when water level is lower than the second water level probe 2, control unit 5 controls the first controllable water valve 1 and opens water inlet in phase cavity, when water level reaches the second water level probe 2, second water level probe 2 and the first water level probe 3 form loop, control unit 5 controls the first controllable water valve 1 and closes, stop water inlet, simultaneously control unit 5 controls single-pole double-throw relay 4 and connects the 3rd water level probe 6, form water level monitoring loop, if broken down, such as the first controllable water valve is closed malfunctioning, then can proceed into water, now water level constantly raises, when water level reaches the height of the 3rd water level probe 6, represent water level abnormality, control unit 5 controls the second controllable water valve 7 and opens and carry out draining, thus effective anti-sealing overflows, avoid dangerous unexpected generation.
