Abstract

The utility model discloses an additional automatic controller for electric heating water distillers, which comprises a float tank and a float. The lower part of the float tank is provided with a water inlet pipe which is controlled by an electromagnetic valve and is connected with a water supply source. The middle upper part of the float tank is also provided with a water outlet pipe which is connected with a water inlet of a water distiller. The utility model is characterized in that the upper end of the float is provided with a travel switch which causes the float to ascend and to descend to control the connection and the disconnection of the power supply of the electric heating water distiller when the water level is changed. The utility model has the advantages of simple structure and reliable operation. When the water is cut off, the power supply of the electric heating water distiller is effectively and automatically cut off. When the water is provided, the power supply of the electric heating water distiller is automatically connected. When the power supply of the circuit is cut off, the electromagnetic valve which controls the water entering is automatically closed.

Description

Electrical distiller adds automaton

The utility model relates to the additional automaton of a kind of electrical distiller.

Electrical distiller is many breadboard essential equipment, electrical distiller ability energized operate as normal when needing continuous water source, if cut off the water supply suddenly or hydraulic pressure reduce, and the power supply of the electrical distiller of failing in time to cut off, the electrical heating elements of electrical distiller is burnt out, even cause the accident.

Task of the present utility model provides the additional automaton of a kind of electrical distiller, and it can cut off the power supply of electrical distiller automatically in the back that cuts off the water, and connects its power supply after the water flowing again automatically.

Task of the present utility model is to realize like this, the additional automaton of this electrical distiller includes float bucket and float, the water inlet pipe that connects with watering of one solenoid control is arranged at float bucket bottom, also have a rising pipe that is connected to the water still water inlet in float bucket middle and upper part, it is characterized in that: there is a travel switch that makes float rising or descend control electrical distiller power connection or disconnection when SEA LEVEL VARIATION the float upper end.

The additional automaton of this electrical distiller is simple in structure, can be effectively automatically with dump after cutting off the water supply, and energized automatically again after the water flowing, but automatic shutoff also after the power failure, reliable operation.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the structural representation of the additional automaton of the electrical distiller that provides of the utility model.

Fig. 2 is the circuit theory diagrams of the additional automaton of the electrical distiller that provides of the utility model.

Among the figure, 1. travel switch XK 2. float bucket 2-1. overflow vent 2-2. rising pipe 2-3. water inlet pipes 3. floats 4. solenoid valve DF

This device is installed in the top a little more than electrical distiller, and its rising pipe 2-2 is connected to the water inlet of electrical distiller, and float bucket 2 can be made of rigid plastic or metal material and all can.The course of work is as follows: see Fig. 1, Fig. 2, as power turn-on plug-in strip K, solenoid valve DF opens, if water flowing, water enters in the float bucket 2, float 3 is risen with water level to be floated, when water level is added to rising pipe 2-2 position, begin to adjust each water swivel to the electrical distiller water filling, make float bucket 2 liquid levels remain on place a little less than gap 2-1, at this moment travel switch XK connects, and it is electric that A.C. contactor C is got, and normally opened contact is connected, make electrical distiller DRQ power connection operate as normal, the first use pinned travel switch with hand before the energising, after water in the electrical distiller adds to water level Jing Chu, unclamp travel switch XK again, make electrical distiller DRQ enter normal operating conditions.When cutting off the water, decline of water table in the float bucket 2, float 3 descends, and travel switch disconnects, A.C. contactor C dead electricity, its normally opened contact disconnects, and the electrical distiller power supply is disconnected.Because the current that have the float bucket to make to enter electrical distiller are balance more.Ifs circuit has a power failure, and solenoid valve DF closes the water inlet pipe 2-3 of float bucket 2, stops into water, has an overflow vent 2-1 on float bucket 2 tops, and inflow is excessive in water inlet pipe 2-3, can overflow from overflow vent 2-1.

Claims

1, the additional automaton of electrical distiller, it includes float bucket and float, the water inlet pipe that connects with watering of one solenoid control is arranged at float bucket bottom, also have a rising pipe that is connected to the water still water inlet in float bucket middle and upper part, it is characterized in that: there is a travel switch that makes float rising or descend control electrical distiller power connection or disconnection when SEA LEVEL VARIATION the float upper end.
