The water heater that has dismountable heat exchanger
Technical field
The present invention relates to a kind of water heater that has dismountable heat exchanger.
Background technology
Traditional Teat pump boiler and solar heat pump and water heating integrated machine still have following defective: the welding of heat exchanger and water tank staving, can not dismounting, and cause the maintenance work trouble; When heat exchanger damages; Need deliver to producer to water-heater water tank and dissect, can not in time change heat exchanger, bring a lot of workloads to maintenance; Maintenance cost is too high, has brought to send to the user and has repaiied expenses.
Summary of the invention
Technical problem to be solved by this invention provides a kind of water heater that has dismountable heat exchanger, and this water heater is energy-conservation, and the thermal efficiency is high, heat exchanger quick-detach and the installation soon in the water tank.
The present invention has adopted following technical scheme: have the water heater of dismountable heat exchanger, comprise water tank, heat-pump hot-water unit, heat exchanger and controller, it is characterized in that: heat exchanger one end is provided with the metal joint that fuses with it; The metal joint end has step and screw thread, and there is through hole at the water tank two ends, after metal joint passes the water tank through hole; Metal joint and water tank contact-making surface have sealing gasket, and sleeve is inserted in metal joint, and through nut check; The water tank through hole stops up with stopper, and heat exchanger is connected with the heat-pump hot-water unit, and sensor is installed in the water tank; Sensor has holding wire to be connected with controller, controller control heat-pump hot-water unit.
The described water heater that has dismountable heat exchanger is characterized in that: heat exchanger is to be shaped to many parallel I-shaped structure arranged with metallic conduit.
The described water heater that has dismountable heat exchanger is characterized in that: water tank is any water tanks such as air-source water heater water tank, solar water heater water tank, condenser tank.
The invention has the beneficial effects as follows the influence that this water heater provides hot water not receive season and the cloudy snow of weather weather, and can in heating, use hot water, energy-conservation, safety, heat is imitated high, and the heat exchanger dismounting is easy to maintenance, long service life.
Description of drawings:
Fig. 1 has the water heater structural representation of dismountable heat exchanger for the present invention.
Fig. 2 is the heat converter structure sketch map.
Below in conjunction with accompanying drawing the present invention is further specified:
The specific embodiment:
Embodiment one:
Like Fig. 1, shown in Figure 2; The water heater that has dismountable heat exchanger comprises water tank (4), heat-pump hot-water unit (1), heat exchanger (2) and controller (3), and the through hole (6) of heat exchanger (2) metal joint (12) from water tank (4) that puts sealing gasket (7) inserts the water tank (4); Metal joint (12) passes from another through hole (13) of water tank (4); Load onto sealing gasket (14), sleeve (8) is put into metal joint (12) step of heat exchanger, locking nut (9); Heat exchanger (2) is connected with heat-pump hot-water unit (1); Through hole (6) stops up with stopper (10), and sensor (5) is installed in the water tank (4), and controller (3) is connected with heat-pump hot-water unit (1) with sensor (5).Described heat exchanger (2) metal joint (12) car has screw thread.Described heat exchanger (2) is to be shaped to many parallel I-shapeds with metallic conduit to arrange.Blast pipe (11) and sensor (5) are installed in the described water tank (4), and controller (3) is connected with heat-pump hot-water unit (1) with sensor (5), and heat exchanger (2) integral body is placed in the water tank (4).Described heat exchanger (2) metal joint (12) and water tank (4) are through nut check.Described heat exchanger (2) has sealing gasket (7) and sealing gasket (14) with water tank (4) inner bag (15) contact-making surface.On described heat exchanger (2) metal joint (12) step sleeve (8) is housed.Described water tank is any water tanks such as air-source water heater water tank, solar water heater water tank, condenser tank.
During this water heater working, sensor (5) reaches controller (3) with signal, when water temperature is lower than setting value; Controller (3) starts heat-pump hot-water unit (1) work, and cold-producing medium absorbs the air heat in a large number through the heat absorption fin, transfers gas phase to by liquid phase; Become high pressure draught through compressor compresses, be defeated by heat exchanger (2), heated the water in the water tank (4); Be reduced to liquid phase after cold-producing medium is caught a cold again, cycle is when water temperature rises to setting value; Controller cuts out heat-pump hot-water unit (1) power supply, accomplishes entire work process.The influence that this water heater provides hot water not receive season and the cloudy snow of weather weather, and can in heating, use hot water, energy-conservation, safety, heat is imitated high, and the heat exchanger dismounting is easy to maintenance, long service life.
