Summary of the invention
The purpose of this utility model is to consider the problems referred to above and a kind of water tank inner space that do not take is provided, the convenient cleaning, and water level control is reliable, the external water-level control apparatus of water dispenser water tank simple in structure.
The technical solution of the utility model is: a kind of water-level control apparatus of water dispenser water tank, comprise raw water box, electric-control system, water pump and clear water tanks, wherein, the delivery port of raw water box communicates by pipeline with the water inlet of clear water tanks, water pump is installed on the pipeline between raw water box delivery port and the clear water tanks water inlet and with electric-control system and is electrically connected, it is characterized in that also comprising water level controller, water level controller is communicated with the refluxing opening of clear water tanks by pipeline, device has electromagnetic induction switch on the bottom lateral wall of water level controller, and electromagnetic induction switch is electrically connected with electric-control system.
Described water level controller is the cylindrical structure, comprise end cap, sealing ring, magnetic float and housing, wherein the top of end cap is provided with outlet pipe, the bottom of housing is provided with water inlet pipe, end cap by screw thread and sealing ring with the magnetic float seal in housing, be symmetrically arranged with mounting ear on the two side of housing and do not hinder the pendulum position of water inlet pipe, water level controller is installed on the inwall of water dispenser shell by mounting ear.
The refluxing opening of described clear water tanks is arranged on the top of clear water tanks, and the set water inlet pipe in water level controller bottom is communicated with refluxing opening by pipeline.
Described raw water box top is provided with overfall, and the set outlet pipe in water level controller top is communicated with overfall by pipeline.
The utility model does not take the water tank inner space owing to adopt external water level controller, and has solved the inner easily problem of breed bacteria of water tank that is arranged at, water quality is not impacted, the water-level control apparatus of this kind mode is convenient simultaneously cleans, and water level control is reliable, and simple in structure.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Embodiment:
As shown in Figure 1, the water-level control apparatus of the utility model water dispenser water tank, comprise raw water box 1, electric-control system 2, water level controller 3, water pump 5 and clear water tanks 6, wherein, the delivery port 12 of raw water box and the water inlet of clear water tanks 61 communicate by pipeline, water pump 5 is installed on the pipeline between raw water box delivery port 12 and the clear water tanks water inlet 61, water level controller 3 devices are above clear water tanks 63, and be communicated with the refluxing opening 63 of clear water tanks by pipeline, device has electromagnetic induction switch 4 on the bottom lateral wall of water level controller 3, and electromagnetic induction switch 4 and water pump 5 are electrically connected with electric-control system 2.
As shown in Figure 2, described water level controller 3 is the cylindrical structure, comprise end cap 31, sealing ring 32, magnetic float 33 and housing 34, wherein the top of end cap 31 is provided with outlet pipe 35, the bottom of housing 34 is provided with water inlet pipe 36, end cap 31 is sealed in magnetic float 33 in the housing 34 by screw thread and sealing ring 32, is symmetrically arranged with mounting ear 37 on the two side of housing 34 and does not hinder the pendulum position of water inlet pipe 36, and water level controller 3 is installed on the inwall of water dispenser shell by mounting ear 37.
The refluxing opening 63 of described clear water tanks is arranged on the top of clear water tanks 6, and the set water inlet pipe 36 in water level controller 3 bottoms is communicated with refluxing opening 63 by pipeline.
In the present embodiment, if when magnetic float 33 lost efficacy, for the water route being carried out the overflow protection, described raw water box 1 top is provided with overfall 11, and the set outlet pipe 35 in water level controller 3 tops is communicated with overfall 11 by pipeline.
Operation principle of the present utility model is: when the magnetic float 33 of water level controller 3 was in low level, magnetic float 33 was pressed close to inductive switch 4 at this moment, and under the effect of magnetic force, inductive switch 4 closures begin to clear water tanks 6 water fillings by electric-control system 2 control water pumps 5 then; Along with clear water tanks 6 water levels constantly increase, water in the clear water tanks 6 overflows from refluxing opening 63 and enters water level controller 3, water level in water level controller 3 continues to go up, until buoyancy of water during greater than magnetic float gravity, magnetic float 33 come-ups are to high-order, this moment, magnetic float 33 was away from inductive switch 4, inductive switch 4 disconnects, stop to clear water tanks 6 water fillings by electric-control system 2 control water pumps 5 then, when fetching boiling water tap 7 water intakings, clear water tanks 6 water levels descend, current in the water level controller 3 of connection clear water tanks 6 return clear water tanks 6, the magnetic float 33 of water level controller 3 inside also descends thereupon, and when magnetic float 33 dropped to low level, water pump 5 was once more to clear water tanks 6 water fillings.
