Abstract
A dry-heating prevention device for the instant electrically-heating water dispenser relates to the field of water dispenser. The dry-heating prevention device is a resistance-type water lever indicator, which is arranged in the water tank of the water dispenser. The resistance-type water lever indicator includes two metal probes inserted under the water level in the water tank; the lower end of the metal probe is close to the bottom of the water tank; the output end of the metal probe is connected with the switch of the power switch. The utility model device can be used together with the thermostat of the heater, and realize the dual dry-heating prevention function, which enhances the dry-heating prevention performance of the instant electrically-heating water dispenser and effectively protects the electric heater.
Description
(1) technical field
The utility model relates to field of water fountain, especially a kind of anti-dry burning device of instant electric heating drinking machine.
(2) background technology
It is healthy that the mode that instant electric heating drinking machine utilizes water flowing to switch on, cut the supply of water and electricity helps drinking-water, and saved a large amount of electric energy.Usually, instant electric heating drinking machine adopts the mechanical temperature controller that is connected to calandria to realize heating together anti-dry control.But, for calandria, mechanical temperature controller take-off by the time, the calandria temperature is too high, and this moment, calandria itself often damaged, and can only select to replace calandria, and therefore the maintenance cost height, is necessary to strengthen the anti-dry performance of heater very much.
(3) summary of the invention
In order to overcome the high deficiency of anti-dry poor performance, maintenance cost of existing instant electric heating drinking machine, the utility model provides a kind of instant electric heating drinking machine anti-dry burning device that strengthens the anti-dry performance.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of anti-dry burning device of instant electric heating drinking machine, described anti-dry burning device is the resistance type water level instrument, described resistance type water level instrument is installed in the water pot of water dispenser, described resistance type water level instrument comprises subsurface two metal probes in the described water pot of insertion, the bottom of described metal probe is near the bottom of described water pot, and its output is connected to the power switch of water dispenser.
Further, described resistance type water level instrument also comprises insulating support, and described metal probe is fixedlyed connected with insulating support, and described insulating support is installed in the top of described water pot.
Operation principle of the present utility model is: the output of described metal probe connects microcomputer control panel, and this microcomputer control panel comprises: be used for the resistance computing module according to the calculated signals resistance value of metal probe; Be used for optionally sending the anti-dry control module of disconnecting power switch instruction according to the resistance value that compares probe and the anti-dry critical resistance value of setting; When the water in the water pot during near the bottom, the resistance value of metal probe reaches critical resistance, and the anti-dry control module is sent the instruction of power cutoff switch, and water dispenser and external power source disconnect.
With respect to prior art, the beneficial effects of the utility model mainly show: can be used with the mechanical temperature controller of calandria, realized dual anti-dry control, strengthened the anti-dry performance of instant electric heating drinking machine, protected electric heating body effectively.
(4) description of drawings
Fig. 1 is the structure chart of anti-dry burning device of the present utility model.
(5) specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, a kind of anti-dry burning device of instant electric heating drinking machine, be the resistance type water level instrument, be installed in the water pot 1 of water dispenser, the resistance type water level instrument comprises subsurface two metal probes 2 in the described water pot of insertion, its bottom is near the bottom of described water pot, and probe 2 is fixed on the top of water pot by insulating bar, and its output is connected to the power switch of water dispenser.
Water dispenser also comprises microcomputer control panel, microcomputer control panel comprises: be used for according to the resistance computing module of the calculated signals resistance value of metal probe 2 and be used for optionally sending the anti-dry control module that disconnecting power switch instructs according to the relatively resistance value and the anti-dry critical resistance value of setting of probe 2.The output of metal probe is connected to microcomputer control panel.
Usually under the state, water level is higher in the water pot 1, two metal probe 2 conductings, and the resistance computing module of microcomputer control panel 3 can calculate the resistance that obtains turning part metal probe 2 by the signal of probe 2, and water level is high more, and the resistance value of probe 2 is more little.Preset water level is near the anti-dry critical resistance of water pot bottom, if water level is very low in the water pot 1, near the water pot bottom, the resistance value of probe is bigger than critical resistance, and at this moment, the anti-dry control module is sent the instruction of disconnecting power switch, and water dispenser and extraneous power supply disconnect.
Claims (2)
1, a kind of anti-dry burning device of instant electric heating drinking machine, it is characterized in that: described anti-dry burning device is the resistance type water level instrument, described resistance type water level instrument is installed in the water pot of water dispenser, described resistance type water level instrument comprises subsurface two metal probes in the described water pot of insertion, the bottom of described metal probe is near the bottom of described water pot, and its output is connected to the power switch of water dispenser.
2, the anti-dry burning device of a kind of instant electric heating drinking machine according to claim 1, it is characterized in that: described resistance type water level instrument also comprises insulating support, described metal probe is fixedlyed connected with insulating support, and described insulating support is installed in the top of described water pot.
