A fast-heating and energy-saving solar water heater water tank relates to the field of solar water heaters, and its function is to realize rapid heating and improve the utilization rate of hot water. The water tank includes two inner water tanks that are not completely separated, inner water tank A and inner water tank B, a normally open solenoid valve connected to the inner water tank, an outer water tank with a detachable window, insulation materials between the inner water tank and the outer water tank, two Vent. When the water needs to be heated, by controlling the switch of the normally open solenoid valve, only part of the hot water that meets the user's needs can be heated, and the cold and hot water in the water tank will not be mixed when the water is used. This is a method that can make the solar water heater easy to use and energy-saving. Insulated water tank.

Description

A fast-heating and energy-saving solar water heater water tank

Technical field:

The utility model belongs to the field of solar water heaters and relates to a solar water heater with electric auxiliary heating function. the

Background technique:

Since the advent of solar collector tubes, solar water heater technology has been greatly developed. At present, solar water heaters have functions such as automatic water supply, water temperature display, water level display, and electric auxiliary heating, making solar water heaters more convenient and reliable to use. the

However, some problems have also been exposed during the user's use. Due to the large water capacity of solar water heaters, the electric auxiliary heating function has the disadvantages of long heating time and high power consumption, and the heated water will gradually cool down if it is not used up, which makes the user experience poor and the electric energy is wasted seriously. the

Utility model content:

The utility model aims to solve the problems of too long electric auxiliary heating time, large power consumption and low utilization rate of hot water, so as to achieve the purposes of rapid heating, energy saving and environmental protection. This kind of water tank includes two inner water tanks that are not completely separated, inner water tank A and inner water tank B, a normally open solenoid valve connected to the inner water tank, an outer water tank with a detachable window, insulation materials between the inner water tank and the outer water tank, two a vent. the

By dividing the inner water tank of the solar water heater insulation water tank into two parts, both inner water tanks can absorb solar energy under the condition of sunny days. In the case of cloudy days, the electric heating structure is used to heat the water in one of the inner water tanks. At the same time, the water temperature and water level sensor detects the water temperature and water level, and sends a signal to the control instrument, and then the control instrument controls the on-off of the normally open solenoid valve to realize heating. Prevent mixing of hot and cold water during process and use of hot water. Reduce the heating time, improve the utilization rate of hot water, and achieve the purpose of energy saving. At the same time, the outsourcing water tank has a removable window for easy maintenance. the

(1) is inner water tank A, (2) is inner water tank second, (3), (7) are air vents, (4) is an outsourcing water tank with a removable window, (5) is a normally open solenoid valve, ( 6) is an electric heating structure, (8) is a water temperature and water level sensor, (9) is an insulation layer, (10) is a heat collector, and (11) is a control instrument. the

Detailed ways:

Hardware composition:

The whole water tank includes an inner water tank A (1), an inner water tank B (2), a normally open solenoid valve (5) connected to the two inner water tanks, an outsourcing water tank (4) with a detachable window, thermal insulation material (9), two Air vents (3) and (7), water temperature and water level sensor (8), electric heating structure (6). Both the inner water tank A (1) and the inner water tank B (2) are connected to the heat collector (10), and the volume of the inner water tank B (2) which needs to be heated by an electric heating structure is the hot water required by one to two adults for bathing The volume of the two inner tanks is coaxial. And the electric heating structure (6) and the water temperature and water level sensor (8) are connected with the control instrument (11), so as to realize the automatic control of the normally open electromagnetic valve (5). The outsourcing water tank (4) has a detachable window at the bottom of the normally open electromagnetic valve (5) that communicates with the inner water tank first (1) and the inner water tank second (2), which is convenient for maintenance of the normally open electromagnetic valve (5). the

Way of working:

When heating water is not needed, the inner water tank A (1) and the inner water tank B (2) absorb solar energy through the heat collector (10) to increase the water temperature, the normally open solenoid valve (5) is opened, and the inner water tank A (1) and the inner water tank The water in the second (2) can flow mutually, so that the water temperature of the inner water tank first (1) and the inner water tank second (2) is the same, thereby identical with the traditional water heater usage. When the water needs to be heated, when the user presses the heating button on the control instrument (11), the normally open solenoid valve (5) is automatically closed, blocking the inner water tank A (1) and the inner water tank B (2), so that the water cannot interact with each other. flow. So the electric heating structure (6) only heats the water in the inner water tank second (2). After heating the water, the inner water tank A (1) and inner water tank B (2) form a temperature difference, the water temperature and water level sensor (8) transmits the temperature difference information to the control instrument (11), and the control instrument (11) keeps the normally open solenoid valve ( 5) Turn it off to prevent the mixing of hot and cold water, so that the water heated by electric heating can be used without waste. When the user finishes taking a shower, the normally open solenoid valve returns to the open state, so the function can be realized. the
