Abstract
The utility model relates to a heating apparatus for heating water, in particular to a water heating apparatus capable of using gas and electric heating. The conventional electric water heating apparatus and the gas water heating apparatus are designed and used respectively. The technical scheme employed by the utility model is that a water inlet port of the gas water heating apparatus 2 is connected with a water inlet pipe 7 of the electric water heating apparatus through a pipeline 1, and a valve 12 and an electric pump 13 are connected with the pipeline 1. One end of the electric water heating apparatus 3 is connected with a cold water pipe 9, and a one-way valve 11 is connected between the water inlet pipe 7 and the cold water pipe 9. A water outlet pipe 5 of the gas water heating apparatus 2 and a water outlet pipe 3 of the electric water heating apparatus are respectively connected with a hot water pipe. The utility model of the water heating apparatus further includes a control circuit. With the technical scheme, the water heating apparatus overcomes the problem of the single heating method of the electric water heating apparatus and the gas water heating apparatus, and simultaneously improves the heating efficiency and the heating speed, and particularly provides convenience to people lived in the vast oil region.
Description
Affiliated field: the utility model relates to a kind of hot-water heating system, particularly a kind of combustion gas and electrically heated hot water apparatus of using.
Prior art: existing electric heater and gas heater all are to design separately to use, and mixing if desired to use to increase a plurality of by-pass valve controls on pipeline, bring a lot of troubles for installation and use.
Summary of the invention: the purpose that the utility model provides is exactly the single heating mode at electric heater and gas heater existence, provides a kind of and can use the hot water apparatus that also can mix use separately.The technical scheme that adopts for achieving the above object is that the water inlet of gas heater 2 is connected by pipeline 1 with the water inlet pipe 7 of electric heater, connects valve 12 and electric water pump 13 on pipeline 1.One end of electric heater 3 is connected on the cold water pipe 10, is connected check valve 11 between water inlet pipe 7 and cold water pipe 10.The outlet pipe 5 of gas heater 2 is connected with hot-water line 8 respectively with the outlet pipe 9 of electric heater 3.
This device also comprises a control circuit, and control circuit is formed by comprising that the jettron 26 that is installed in electric heater 24, temperature controller 22, the change-over switch 23 in the electric heater 3 and is installed in the indicator lamp 25 of electric heater 3 appearances and controls electric water pump 13 interconnects.Its method of attachment is the input connection protector 21 at power supply; the output of protector 21 connects temperature controller 22, and the change-over switch 23 of temperature controller 22 connects respectively by the loop of jettron 26 and 13 series connection of electric water pump and by the loop of indicator lamp 25 and electric heater 24 parallel connections.
Adopt the hot water apparatus after this technical scheme, overcome electric heater and the single problem of gas heater mode of heating, improve the efficiency of heating surface and firing rate simultaneously, convenient especially vast oil district resident uses.
Description of drawings: accompanying drawing 1 is a syndeton schematic diagram of the present utility model; Fig. 2 is the control circuit circuit theory diagrams.
The specific embodiment: embodiment 1: with reference to accompanying drawing, the water inlet of gas heater 2 is connected by pipeline 1 with the water inlet pipe 7 of electric heater, on pipeline 1, connects valve 12 and electric water pump 13.The water inlet pipe 7 of electric heater 3 is connected on the cold water pipe 10, is connected check valve 11 between water inlet pipe 7 and cold water pipe 10.The outlet pipe 5 of gas heater 2 is connected with hot-water line 8 respectively with the outlet pipe 9 of electric heater 3.
Embodiment 2: on the basis of embodiment 1, increase a control circuit.Control circuit is formed by comprising that the jettron 26 that is installed in electric heater 24, temperature controller 22, the change-over switch 23 in the electric heater 3 and is installed in the indicator lamp 25 of electric heater 3 appearances and controls electric water pump 13 interconnects.Its method of attachment is the input connection protector 21 at power supply; the output of protector 21 connects temperature controller 22, and the change-over switch 23 of temperature controller 22 connects respectively by the loop of jettron 26 and 13 series connection of electric water pump and by the loop of indicator lamp 25 and electric heater 24 parallel connections.Jettron 26 is being controlled electric pump working, when in the tracheae 14 air pressure being arranged, jettron 26 is connected, when opening valve 12, connect electric water pump 13 power supplys, by gas heater 2 cold water in cold water pipe 10 or the electric heater 3 is heated, by delivery port 5 hot water is delivered to electric heater 3 then or directly send into hot-water line 8 uses.When in the tracheae 14 during no air pressure, jettron 26 disconnects, gas heater 2 stops heating, and at this moment, the change-over switch 23 of the temperature controller 22 in the electric heater 3 is transformed into the electrical heating loop, electric heater 24 work, indicator lamp 25 sends the heating indication simultaneously, and when the hot water in the electric heater 3 reached design temperature, the change-over switch 23 of temperature controller 22 disconnected electric heater 24 loops, stop heating, indicator lamp goes out.
