Instant solar water heater

Abstract

The invention relates to an instant solar water heater which comprises a water heater main body and a water temperature controller, wherein the water heater main body comprises a ceramic water pipe, a synthesized heat-insulating layer covering the ceramic water pipe and an outer metal layer arranged outside the synthesized heat-insulating layer, a high-temperature resistor is arranged in the ceramic water pipe, two ends of the high-temperature resistor are connected with resistor connecting wires by which a solar power supply is connected to the high-temperature resistor for heating via the water temperature controller; a thermocouple is arranged in the ceramic water pipe and is connected to a temperature regulator of the water temperature controller through a thermocouple connecting wire. The instant solar water heater does not need preheating and waiting, is very quick and convenient, time-saving, material-saving, small in size, light in weight, easy to assemble and can be directly connected with a tap water pipe; because the temperature of water is constant, the instant solar water heater is comfortable to use; and the instant solar water heater is free of scaling, long in service life, safe, environment-friendly and energy-saving and does not generate waste gas and noise.

Description

technical field [0001] The invention relates to a water heater, in particular to a solar energy instantaneous water heater which provides a heating source by solar energy. Background technique [0002] The water heaters currently on the market mainly include the following types: [0003] Water storage type electric water heater, the hot water takes a long time, you have to wait, and you can’t use hot water temporarily; the amount of hot water you need is difficult to control, and the water will be boiled for a long time, and it will cool down if you don’t use it in time, wasting electricity; the volume is average If the water heater is too large, the larger the family population, the larger the water heater will take up space for installation. If the water heater is not big enough, you will have to line up to burn it for bathing; the water heater will be powered on for a long time, and the temperature will be kept above 60 degrees for a long time. Therefore, it is easy to b...

[0003] Water storage type electric water heater, the hot water takes a long time, you have to wait, and you can’t use hot water temporarily; the amount of hot water you need is difficult to control, and the water will be boiled for a long time, and it will cool down if you don’t use it in time, wasting electricity; the volume is average If the water heater is too large, the larger the family population, the larger the water heater will take up space for installation. If the water heater is not big enough, you will have to line up to burn it for bathing; the water heater will be powered on for a long time, and the temperature will be kept above 60 degrees for a long time. Therefore, it is easy to be damaged; the heat loss of hot water in the pipeline is large; the waiting time for water is too long; a certain amount of cold water must be wasted before the hot water flows out. L / time

[0004] Gas water heaters have peculiar smell and are not environmentally friendly, and the exhaust gas is easy to leak, which is not safe enough. Especially if you live in a high-rise residence, the air pressure outside the building is high, which can easily cause exhaust gas backflow. It is especially not suitable for use in kitchens and bathrooms with poor ventilation conditions. The heat is in the open space. Severe loss, not enough insulation

[0005] Solar water heaters all claim to be energy-saving, but in fact, the use of such solar water heaters in most parts of China is not energy-saving, because solar water heaters heat water by absorbing the heat of sunlight. The amount of hot water required is not large, and the three seasons of spring, autumn, and winter, when the real demand for hot water is relatively large, rely entirely on long-term electric auxiliary heating. Moreover, we generally use hot water more at night, that is to say At night, after the hot water is used up, there is cold water in the tank, and there is no sun at night, then the electric heating will start, the solar water tank is not fully enclosed, it will be heated and kept warm intermittently, and when the sun comes out at dawn, the water will be hot That’s right, the effect of the sun is not great, so this kind of solar water heater is not energy-saving; in addition, its installation is more complicated. If it is not installed properly, it will affect the appearance, quality of the house and the appearance of the city; The water temperature is not hot enough, there are vent holes, and the heat dissipation is fast

[0006] Instant electric water heaters require high power and high circuit current capacity, which poses safety hazards and are not suitable for old-fashioned houses with electric meters below 10 amps.
