Description
Technical field
This utility model relates to the drinking machine apparatus realizing automatically powering off under a kind of night or anhydrous state, is by spacing
The Guan Bi of switch disconnects the ON-OFF with IGCT and realizes the power-off protection of water dispenser.
Background technology
Under current social, water dispenser, with its light little convenient, inexpensive feature, is increasingly favored by people.So
And in routine use, water dispenser easily occurs that the situation of no-water dry combustion or not power-off at night, no-water dry combustion easily cause drinking-water
The damage of machine components and parts, even initiation fire accident；And forget night to water dispenser power-off, in Ze Shi family or public place relatively
For universal phenomenon, not power-off at night, on the one hand significantly waste power resource, on the other hand there is also certain safety hidden
Suffer from.At present the most ripe about the research of this respect, more existing theories are asked due to the complexity of its structure or high cost etc.
Topic, is difficult to apply to actual production.
Summary of the invention
This utility model mesh is that design is a kind of in hydropenia or not used time at night, it is achieved the water dispenser of the function automatically powered off,
Solve problem present in background technology.
The technical solution of the utility model is accomplished by:
This utility model includes rigid insulation push rod, crossheading, normally closed type limit switch, photoconductive resistance, IGCT, its feature
Being: rigid insulation push rod is directly installed in tank on buoyancy aid, middle matching with crossheading slides up and down, and the other end is with normally closed
Formula limit switch is combined；Crossheading directly and is arranged on tank right-hand member；Normally closed type limit switch is directly installed on the total road of circuit；
Photoconductive resistance is directly installed on drinking machine crust, is placed in blister pack；IGCT is directly installed on heater circuit,
Control pole G end to be connected with photoconductive resistance conducting wire at lower end.
Wherein, by the location of crossheading movement locus, it is ensured that rigid insulation push rod and limit switch button upper next
Cause property.
Further, the built-in back-moving spring of normally closed type limit switch, there is auto-reset function.
Further, circuit is provided with IGCT and photoconductive resistance components and parts combination unit.
This utility model has the advantage that compared with prior art
1. use rigid insulation push rod, according to the height of water level, in conjunction with limit switch, it is achieved circuit during anhydrous or hydropenia
Automatically disconnecting, when water level recovers, normally closed type limit switch automatically resets, and circuit recovers normal work.Simple in construction, controls spirit
Quick, practical and convenient, ensure safety.
2. being applied in combination by photoconductive resistance and two elements of IGCT, nobody automatically powers off merit can to realize night
Can, reasonable in design, simple in construction, cost is relatively low, and can effectively save electric energy, prevent accident.
3. the power-off protection of two kinds of situations does not interfere with each other, and be respectively provided with and automatically control and auto restore facility, it is to avoid people
The carelessness of work operation, is combined by the two, substantially increases the self-protection function of water dispenser, and the effectively save energy, whole
Body design advantages of simple, it is easy to put into actual production and application.

Detailed description of the invention
(1) hydropenia or anhydrous time automatically power off
As depicted in figs. 1 and 2, water dispenser in water shortage or automatic power-off device for waterless include normally closed type limit switch 1, hard
Insulation push rod 2, crossheading 3, buoyancy aid 4 and tank 5, is characterized in that: normally closed type limit switch 1 designs on circuit main line, built-in multiple
Position spring, has auto-reset function, and rigid insulation push rod 2 is fixedly linked with buoyancy aid 4, and moves up and down with buoyancy aid 4, and hard is exhausted
Edge push rod 2 is by crossheading 3 guide function, it is ensured that consistent with the perpendicularity up and down of limit switch button.
Specific works process: when water level is normal in tank 5, buoyancy aid 4 floats in the water surface, rigid insulation push rod 2 and normally closed type
Limit switch 1 keeps released state, circuit to be held on, and normally works；When in tank 5 water level too low or anhydrous time, buoyancy aid 4 times
Moving, drive rigid insulation push rod 2 to be moved down by crossheading, rigid insulation push rod 2 right-hand member promotes normally closed type limit switch 1 button, opens
Closing and disconnect, whole circuit no longer works；When again adding water, in tank 5, water level recovers normal, and buoyancy aid 4 drives rigid insulation to push away
Bar 2 moves on the whole, and rigid insulation push rod 2 separates with normally closed type limit switch 1, and under the effect of back-moving spring, normally closed type is spacing
Switch 1 recovery Guan Bi, circuit turn-on, normally work.Overall structure is simple, controls accurately, it is achieved thoroughly power-off, protective value
Good.
(2) the automatically powering off of not used time at night
As depicted in figs. 1 and 2, night without auto-power-off device include photoconductive resistance 9, IGCT 13, protective resistance 8,
Add thermal resistance 12, power supply indicator 10 and burner on light 11, be characterized in: photoconductive resistance 9 change in resistance scope is big, has bigger
Pressure drop difference；IGCT 13 regulates by controlling pole G, it is achieved the on or off of self；IGCT 13, add thermal resistance 12 and add
Thermal light 11 is in same circuit, and photoconductive resistance 9, protective resistance 8 and power supply indicator 10 are in same circuit；Brilliant lock
Pipe 13 controls pole G end and is connected to below photoconductive resistance 9.
Specific works process: when night nobody time, dim, photoconductive resistance 9 resistance becomes big, and IGCT 13 controls pole G
End level reduces, and IGCT 13 is become cut-off from conducting, and heater circuit disconnects, and adds thermal resistance 12 and no longer works, burner on light
11 close, it is achieved unmanned protection at night.When having people night, indoor light is opened, and light brightens, and photoconductive resistance 9 resistance diminishes,
IGCT 13 controls pole G end level and raises, and IGCT 13 is become conducting from cut-off, and heater circuit turns on, and adds thermal resistance 12 and starts
Work, burner on light 11 is opened.
Anhydrous or night, the used time did not automatically powered off, two kinds of situations do not interfere with each other, and any situation all can realize when occurring
Power-off protection, and all there is auto-reset function, add double shield to existing water dispenser equipment, it is achieved that multifunction
Automatic circuit break function.
Obviously, above-described embodiment of the present utility model is only used to clearly demonstrate the citing that this utility model is done,
And it is not the restriction to this utility model embodiment.For art to those of ordinary skill for, state upper
Can also make other changes in different forms on the basis of bright.Here all of embodiment cannot be carried out one by one
Enumerate.Every belong to obvious change that the technical solution of the utility model amplified out or variation still in this practicality newly
Within the protection domain of type.
