Abstract

The utility model especially relates to an electric heat boiler comprising a shell and a power electric circuit. An inlet pipe connects with the shell, the power electric circuit inculdes a power and a protective circuit, an electric heat main circuit, a control electric circuit and a signal light electric circuit. The signal light electric circuit is formed by a working indicator light XD2 and a power indicator light XD1 which connect in parallel with the power and the protective circuitformed by the loading switch QS and the insurancer FU, the electric circuit comprises an electric component R, the control electric circuit controls the transmission of the electric heat component R, a constant open switch is connected in series on one end of the electric heat component R, and the other end connects to a temperature-controller JW in series and connects to the electric water valve FS in parallel, the electric water valve is connected with the inlet of the inlet to prevent burning without water and keep the high temperature of the warm water. The utility model can achieve the effect of antisepsis to the water and prevent the cool water mixing with the original hot water to cause the unsanitation.

Description

Electric water boiler

Technical field

The utility model is specifically related to electric water boiler.

Background technology

Common electric water boiler, all be to adopt float-ball type valve control water inlet, when the user connects when using boiling water from boiled water tank, ball float in the storage tank is just followed the decline of water level and Open valve continues to flow into water tank cold water, and flows directly in the boiled water tank by water inlet pipe, make the cold water boiling water mix (water), therefore the inaccessible effective scalding of boiling water of being emitted does not meet hygienic requirements, hinders people's healthy shortcoming.

The utility model content

The purpose of this utility model is to solve above-mentioned shortcoming, and a kind of electric water boiler that closes inlet valve automatically is provided.

For achieving the above object: comprise housing and power circuit; link to each other with housing and to be connected to water inlet pipe; power circuit comprises power supply and holding circuit; the electric heating main circuit; control circuit and tally circuit are electrically connected and form; tally circuit is parallel to power supply and the holding circuit of being made up of on-load switch QS and protector FU by relay indicating light XD2 and power supply indicator XD1; its electric heating main circuit is that heating R forms; the conducting of control circuit control heating R; be in series with normal open switch K on the end of heating R; the other end is series on temperature controller JW and electric water valve FS be in parallel, and the water inlet pipe water inlet is connected with electric water valve.

Described heating R is electrically connected on the normally open contact KM on the control circuit; the end of contactor KM on the control circuit excessive low water level protection travel switch LK that is connected in series; the other end is in parallel with electric water valve FS and is connected; be in series with temperature controller JW on the common end of contactor control piece KM1 and electric water valve FS, heating R is the heating R of three-phase standard.

The beneficial effects of the utility model: this structure is provided with electric water valve FS and excessive low water level protection travel switch LK, prevent the cold water boiling water mix (water) guarantee to take out drink be the high-temperature water of boiling and automatically the timely amount of makeup water of water inlet boil heat.

The specific embodiment

As Fig. 1; shown in 2; comprise housing 1 and power circuit 2; link to each other with housing 1 and to be connected to water inlet pipe 3; power circuit 2 comprises power supply and holding circuit 4; electric heating main circuit 5; control circuit 6 and tally circuit 7 are electrically connected and form; tally circuit 7 is parallel to power supply and the holding circuit of being made up of on-load switch QS and protector FU 4 by relay indicating light XD2 and power supply indicator XD1; its electric heating main circuit 5 is that heating R forms; the conducting of control circuit 6 control heating R; be in series with normal open switch K on the end of heating R; the other end is series on temperature controller JW and electric water valve FS be in parallel, and water inlet pipe 3 water inlets are connected with electric water valve 8.

When water temperature reaches when boiling, temperature controller JW automatic disconnection, temperature controller JW dead electricity, electric water valve FS and heating R be dead electricity also, and electric water valve FS dead electricity stops into that water and heating R no longer heat.

As shown in Figure 3; described heating R is electrically connected on the normally open contact KM on the control circuit 6; the end of contactor KM on the control circuit 6 excessive low water level protection travel switch LK that is connected in series; the other end is in parallel with electric water valve FS and is connected; be in series with temperature controller JW on the common end of contactor control piece KM1 and electric water valve FS, heating R is the heating R of three-phase standard.

When lack of water, excessive low water level protection travel switch LK plays protection outage, the coil losing electricity of contactor KM and normally open contact KM that heating R is electrically connected disconnects, and heating R outage stops heating; Or water reaches when boiling, and temperature controller JW also cuts off the power supply and makes contactor KM dead electricity, makes heating R stop heating.
