Abstract
The invention discloses an electric water heater with solar photovoltaic power supply. The electric water heater comprises a solar heat collection panel and a water tank placed indoors, wherein an electric heating tube I which can be connected with a direct current power supply and an electric heating tube II which can be connected with an alternating current power supply are arranged inside the water tank; through photovoltaic conversion, the solar heat collection panel transmits a direct current onto the electric heating tube I for heating through a connecting wire; and the electric heating tube II is connected with an external 220V alternating current. According to the electric water heater, when in cloudy days or rainy days and when heat energy of the solar heat collection panel is insufficient, the electric heating tube II automatically switches on and connects with the alternating current power supply to heat water, and the situation that no hot water can be utilized due to insufficient sunlight illumination is avoided; and further, the solar heat collection panel transmits electric energy into the indoor water tank through photovoltaic conversion, and when the water tank outputs water, only part of cold water in a water pipe requires to be discharged, so that the water resource is saved, and the waste is avoided.
Description
Technical field
The present invention relates to a kind of electric heater, be specifically related to a kind of with solar photovoltaic powered electric heater.
Background technology
Existing solar water heater includes water tank, solar energy heat collection pipe, bracing frame and base, bracing frame and solar energy heat collection pipe are set on described base, water tank is set on support frame as described above, described water tank is connected with solar energy heat collection pipe, arranging inner bag and outer gallbladder in water tank, arrange polyurethane insulation coating between described inner bag and outer gallbladder, the lower section of described solar energy heat collection pipe arranges reflector, one end of described reflector is arranged on bracing frame, and the other end is arranged on base.Though above-mentioned solar water heater can saves energy there is also many defects, water temperature as inadequate in sunshine will be difficult to improve；For another example the cold water from storage tank to the longest indoor intercepting drain, must bleed off when reinstating and just can use, also result in the waste of water resource；For another example it is necessarily mounted on roof or level land, takies bigger space.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention provide a kind of rational in infrastructure, water temperature is high, save water resource electric heater.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of with solar photovoltaic powered electric heater, including solar heat-collection plate, it is placed on indoor water tank, the electric heating tube I that can connect DC source and the electric heating tube II that alternating current power supply can be connected it is provided with in described water tank, described solar heat-collection plate passes through opto-electronic conversion, being sent on electric heating tube I heat by DC current by connecting line, described electric heating tube II connects outside 220V alternating current wires.
In the present invention, connect on described electric heating tube II and have inductive switch, described inductive switch is connected with the temperature inductor being positioned at water tank and the DC voltage detecting device being connected on electric heating tube I, when temperature inductor and DC voltage detecting device detect less than setting value, inductive switch is opened, and electric heating tube II is started working.
In the present invention, in described 220V alternating current wires, connection has the audible-visual annunciator for detecting electric leakage.
The invention has the beneficial effects as follows: when cloudy day or rainy day, when the heat energy of solar heat-collection plate is inadequate, electric heating tube II then automatically opens up connection alternating current and heats, it is to avoid cause the situation appearance used without hot water because illumination is not enough；Further, described solar heat-collection plate delivers the power to, in the water tank of indoor, only to bleed off the cold water in part water pipe, saved water resource during water tank water outlet by opto-electronic conversion, it is to avoid waste；Further, solar heat-collection plate need not carry water tank and accumulator, reduces volume, weight and cost, it is possible not only to be arranged on balcony or roof, can also mount or on the vertical balcony being contained on the sunny side, fitting limit is wide, and without revising the water lines of original water heater when installing.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of the present embodiment.
Detailed description of the invention
With reference to Fig. 1, it is a kind of with solar photovoltaic powered electric heater that the present embodiment is provided, including solar heat-collection plate 1, it is placed on the water tank 2 of indoor, the electric heating tube I 3 that can connect DC source and the electric heating tube II 4 that alternating current power supply can be connected it is provided with in described water tank 2, described solar heat-collection plate 1 passes through opto-electronic conversion, it is sent on electric heating tube I 3 heat by DC current by connecting line, described electric heating tube II 4 connects outside 220V alternating current wires, described electric heating tube I 3 and electric heating tube II 4 may be located at the same side of water tank 2 or lay respectively at both sides, there is identical technique effect.When electric heating tube I 3 and electric heating tube II 4 lay respectively at both sides, electric heating tube I 3 can be arranged at water inlet end, electric heating tube II 4 is arranged at water side.
As preferred embodiment, connect on described electric heating tube II 4 and have inductive switch 5, described inductive switch 5 is connected with the temperature inductor 6 being positioned at water tank 2 and the DC voltage detecting device 7 being connected on electric heating tube I 3, temperature inductor 6 and DC voltage detecting device 7 detect when the water temperature in water tank 2 and the DC voltage detected on electric heating tube I 3 are less than setting value, inductive switch 5 is opened, and electric heating tube II 4 is started working.User can regulate setting value according to self demand, and if desired can two add heat pipe and work simultaneously, improve firing rate.Also can connect on inductive switch 5 and have time counter, user can set the time period needing hot water to have a bath, it is not necessary to round-the-clock unlatching heating mode, reaches the purpose of energy-conserving and environment-protective.
Further, described 220V alternating current wires connecting and has the audible-visual annunciator 8 for detecting electric leakage, audible-visual annunciator 8 one end is connected on ground wire, and one end is connected on zero line, when there is leaky, then sends sound or light prompt signal, to improve security performance.
The foregoing is only the preferred embodiments of the present invention, as long as realizing within the technical scheme of the object of the invention broadly falls into protection scope of the present invention with essentially identical means.
