Abstract

The utility model relates to a dual-purpose water heater using the solar energy or the electric heating, which comprises a shell, a back cover, a water inlet pipe, a water outlet pipe, an electric heater, a relay, a buzzer and a water level indicator light. The utility model is characterized in that a solar energy receiving matrix in the parabolic curve and the curved surface shapes is arranged on the shell, and the inner cavity of the shell is provided with a reinforcing baffle plate and an electric heater. Because of the solar energy receiving matrix in the parabolic curve and the curved surface shapes is provided, the energy conversion ratio can be raised. Because the electric heater is also provided, the bath under the condition of no light irradiation can be ensured. The utility model has the advantages of simple structure and low production cost.

Description

Solar-electricity heats dual-purpose water heater

The utility model relates to the fluid heater technical field, and particularly a kind of home-use solar-electricity heats dual-purpose water heater.

At present the employed water heater of family mainly contains two types of gas heater and electric heating type water heaters, wherein the gas-type water heater needs coal gas or liquefied petroleum gas as heating source, in use be easy to generate carbon monoxide and carbon dioxide, poisoning takes place; Though and there is not problem of environmental pollution in the electric heating type water heater, the rising of the temperature that can not conform will expend certain electric energy and just can reach the purpose that adds hot water; If will use solar energy as the energy, very big reception solar energy equipment be arranged, the shortcoming that it exists is to take up room greatly, and infusion of financial resources is high, and energy conversion rate is low.

The purpose of this utility model provides a kind of simple in structure, the dual-purpose water heater of no air-polluting energy-saving solar electrical heating.

The utility model is achieved in that it comprises housing, bonnet, water inlet pipe, outlet pipe, electric heater, relay, buzzer and water level indicator light is characterized in that being provided with parabolic surface solar energy receiving matrix on housing, be provided with at the inner chamber of housing and strengthen dividing plate and electric heater.

The utility model can improve the conversion ratio of energy owing to be provided with parabolic surface solar energy receiving matrix, also owing to be provided with electric heater unit, just can guarantee bathing under the condition of unglazed photograph, also have simple in structure, the advantage that production cost is low.

Below in conjunction with accompanying drawing the utility model is further described,

Fig. 1 is the structural representation that solar-electricity heats dual-purpose water heater,

Fig. 2 is the left view of Fig. 1,

Fig. 3 is the circuit diagram that solar-electricity heats dual-purpose water heater,

As Fig. 1--shown in 3, this solar-electricity heats dual-purpose water heater and comprises housing 1, bonnet 2, water inlet pipe 3, outlet pipe 4, electric heater 5, relay J Y, JY1, JY2, buzzer 6 and water level indicator light D1--D2, be provided with groove 7 in housing 1 regularity, at the higher dope layer of inner chamber coating one thermal conductivity factor of groove 7 outer surfaces and housing 1, these grooves 7 have constituted parabolic surface solar energy receiving matrix 8, are provided with at the inner chamber of housing 1 and strengthen dividing plate 9 and electric heater 5, its circuit theory be electric heater 5 with by liquid level relay JY, normally closed relay JY1 and normally opened relay JY2, low water level indicator lamp D1, the warning indicating circuit that high water level relay D2 and buzzer 5 constitute is in parallel, during use, in housing, inject cold water, when solar irradiation is mapped on the parabolic surface solar energy receiving matrix, produce and focus on and the multiple spot refraction, be plated in groove 7 lip-deep dope layers and have higher thermal conductivity factor owing to be coated with, the heat radiation of solar energy is converted into the heating to water, uses for bathing; When unglazed according to the time, can connect K switch, electric heater 5 work is also heated for cold water.

Claims

1, a kind of solar-electricity heats dual-purpose water heater, and it comprises housing, bonnet, water inlet pipe, outlet pipe, electric heater, relay, buzzer and water level indicator light is characterized in that being provided with parabolic surface solar energy receiving matrix on housing, be provided with at the inner chamber of housing and strengthen dividing plate and electric heater.

2, root a tree name right wants 1 described solar-electricity to heat dual-purpose water heater, it is characterized in that on housing the regular groove that is provided with, at the outer surface of groove and the higher dope layer of inner chamber coating one thermal conductivity factor of housing, these grooves have constituted parabolic surface solar energy receiving matrix.
