Abstract
The utility model provides an electric water heater capable of preventing a heating tube from dry heating and low-water-pressure outage, comprising a liner and the heating tube, wherein the liner is provided with a flange opening, a water inlet pipe, a hot water outlet pipe and a dirt discharging pipe; the heating tube is fixedly arranged on a flange disc; and the flange disc is fixedly connected with the flange opening. The electric water heater is characterized by further comprising a pressure switch; the pressure switch is communicated with an inner cavity of the liner; and the pressure switch is connected with a power supply and the heating tube. With the adoption of the structure, the heating tube cannot start to work before the water heater is full of water, so that a phenomenon of the dry heating of the water heater is avoided and the factor of damaging the water heater due to the dry heating is eliminated. When hot water is used, pressure of the liner of the water heater is reduced, so that the power supply is cut off and the electric water heater is safer.
Description
Technical field
The present invention relates to a kind of electric heater.
Background technology
Present prior art, a kind of electric heater comprises inner bag and heat-generating pipe, and flange port, water inlet pipe, hot water outlet pipe and blow-off pipe are arranged on the described inner bag; Described heat-generating pipe is fixed on the ring flange, and ring flange is fixedly connected with flange port.Existing problems are: can not effectively prevent dry combustion method, low hydraulic pressure outage.
Summary of the invention
The objective of the invention is: the electric heater of the anti-heat-generating pipe dry combustion method of a kind of energy and the outage of low hydraulic pressure is provided, and it can prevent that heat-generating pipe work eliminates safe hidden trouble under low hydraulic pressure or the anhydrous state.
The present invention is achieved in that the electric heater of the anti-heat-generating pipe dry combustion method of a kind of energy and the outage of low hydraulic pressure, comprises inner bag and heat-generating pipe, and flange port, water inlet pipe, hot water outlet pipe and blow-off pipe are arranged on the described inner bag; Described heat-generating pipe is fixed on the ring flange, and ring flange is fixedly connected with flange port; Its special character is: also comprise a pressure switch, described pressure switch communicates with the inner chamber of inner bag, and pressure switch is connected with heat-generating pipe with power supply.
The electric heater of the anti-heat-generating pipe dry combustion method of described a kind of energy and the outage of low hydraulic pressure, its special character is: described pressure switch is fixed on the ring flange.
The electric heater of the anti-heat-generating pipe dry combustion method of described a kind of energy and the outage of low hydraulic pressure, its special character is: also comprise a temperature controller, described temperature controller one end is connected with pressure switch, the other end is connected with heat-generating pipe; Temperature controller and inner bag are fitted.
The electric heater of the anti-heat-generating pipe dry combustion method of described a kind of energy and the outage of low hydraulic pressure, its special character is: also comprise a temperature limiter, described temperature limiter one end is connected with pressure switch, the other end is connected with power supply; Temperature limiter arranges on the inner bag.
The electric heater of the anti-heat-generating pipe dry combustion method of a kind of energy of the present invention and the outage of low hydraulic pressure, because adopt such structure, before water heater was not filled with water, heat-generating pipe was fail to start work, stop the phenomenon of water heater dry combustion method, so just eliminated the factor of damaging water heater because of dry combustion method.When using hot water because of the pressure decreased of water heater water courage, thereby cut off the electricity supply, safer.
