Description
The utility model relate to a kind of for shower, wash one's face and rinse one's mouth and other washing provides the electric heater of hot water.
At present, family, enterprises and institutions, service trade etc. are used for shower, wash one's face and rinse one's mouth and the electric heater of other washing mainly comprises water tank and electric heating system.Human electric shock when these electric heaters prevent to use with earth leakage protective device with mainly being abutted against; under imperfect earth (perhaps earth connection can't be installed) and earth leakage protective device situation out of control; charged bathing or washing may jeopardize personal safety because of the electric heating system electric leakage.Safest using method is, fills with earlier water in water tank, and the power supply of connecting electric heating system is heated to the water in the water tank temperature required, and the power supply that cuts off electric heating system then carries out bathing or washing.After hot water in the water tank uses up, connect the power supply of electric heating system again, the water in the water tank is heated.Cut off the electricity supply and connect power supply and all need manually-operated, bathing or washing once repeat repeatedly this operation possibly, and after using up a water tank hot water, connect the power supply heating once more, also to stop bathing or washing, cold water in the wait water tank is heated to temperature required, and troublesome poeration uses very inconvenient.
The purpose of this utility model is, provide a kind of can automatic disconnection electric heating system power supply when opening valve, when valve-off, can connect the electric heater of electric heating system electricity automatically.
The purpose of this utility model is to realize like this, the electric heater of band pressure switch, comprise water tank and electric heating system, their special character is, also comprise pressure switch and pressure sensitive pipe, pressure switch is installed in an end of pressure sensitive pipe, and the other end of pressure sensitive pipe is communicated with water tank, tank inlet pipe and radiator drain thrin, and pressure switch is controlled switching on and off of electric heating system power supply.
The pressure sensitive pipe is used for being communicated with various water pipes or water tank, thereby the pressure variety in water pipe or the water tank is passed to pressure switch.The pressure sensitive pipe is as long as be communicated with water tank, tank inlet pipe and radiator drain thrin, all in protection domain of the present utility model.When the utility model was used for the outlet open-type electric heater, the caliber of pressure sensitive pipe must be less than the caliber of tank inlet pipe and radiator drain.The utility model in use, valve open or close and the pressure that produces changes makes switching signal of pressure switch output.Pressure switch of the present utility model should be made broad understanding, as long as what can change a switching signal of output with the pressure of water all is the pressure switch of the utility model indication, its inside also can comprise control circuit and/or relay.Pressure switch generally is to come output switching signal by the contact.Pressure switch can directly be controlled switching on and off of electric heating system power supply, for example normally-closed contact is connected in the major loop of electric heating system.Pressure switch also can be controlled switching on and off of electric heating system power supply by other control circuit.When valve open of the present utility model (outwards heat supply water), pressure switch disconnects the power supply of electric heating system, and when valve closing of the present utility model (stopping heat supply water), pressure switch is connected the power supply of electric heating system.
Can disconnect or connect under the situation of big electric current in pressure switch, the normally-closed contact of pressure switch of the present utility model can be connected in the major loop of electric heating system.
Safer in order to use, two normally-closed contacts of pressure switch of the present utility model are connected on respectively among the live wire and zero line of major loop of electric heating system.
Can not disconnect or connect under the situation of big electric current in pressure switch, can connect with the coil of relay in the contact of pressure switch of the present utility model, and the normally-closed contact of relay is connected in the major loop of electric heating system.
Equally, safer in order to use, two normally-closed contacts of relay of the present utility model are connected on respectively among the live wire and zero line of major loop of electric heating system.
The utility model is owing to have pressure switch, when opening the outside heat supply water of valve, and the power supply that pressure switch can the automatic disconnection electric heating system.When bathing or washing, because power supply is cut off automatically, human electric shock's phenomenon can not take place, improved the security used than existing electric heater like this.In bathing or washing process, the temporary close valve, pressure switch can be connected the power supply of electric heating system automatically, and the water in the water tank is heated at any time.The utility model is compared with existing electric heater, connects power supply and all carries out automatically with cutting off the electricity supply, and does not need repeatedly artificial the disconnection and the connection power supply in the use, and is easy to use.Because during the utility model valve-off, pressure switch can be connected power supply and at any time the water in the water tank be heated, do not need as existing electric heater, behind the hot water in using up water tank, also will connect power supply heats whole one case cold water in the water tank, time to be heated such as reduced, used convenient.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
