Description

High-efficiency solar water heater insulation water tank

technical field

The utility model relates to a solar water heater, in particular to a high-efficiency solar water heater insulation water tank.

Background technique

The solar water heater water tank is composed of an inner tank and an outer heat insulation layer and an outer shell. The water inlet and outlet pipes, overflow pipes and ventilation pipes are all connected to the water tank shell. The ventilation pipe connected on the solar water heater water tank is to make the water tank communicate with the atmosphere, so that the water injection and water discharge operations of the solar water heater can be carried out smoothly. However, the installation position of the ventilation pipe of the existing solar water heater water tank is either on the top surface of the water tank shell, or on the uppermost end of the water tank shell side, and its openings are all set upwards, so that the water tank is connected to the atmosphere. While functioning, the heat of the hot water stored in a large amount of water tanks will be discharged out of the box through the upper opening of the ventilation pipe, causing the temperature of the hot water stored in the solar water heater water tank to drop. Especially in the colder seasons, the temperature difference between the inside and outside of the water tank is large, and a large amount of heat is lost, which often leads to the low temperature of the stored hot water and makes the user unable to take a bath, thus shortening the use of the solar water heater in a year. time limit.

Utility model content

The purpose of this utility model is to provide a high-efficiency solar water heater insulation water tank that overcomes the defects of the prior art, so as to effectively reduce the heat loss of the water stored in the water tank and prolong the service life of the solar water heater.

The utility model is achieved in the following way: a high-efficiency solar water heater heat preservation water tank, the water tank shell is composed of an inner tank, an outer heat insulation layer and an outer shell, and the water inlet and outlet pipes, overflow pipes and ventilation pipes lead into the water tank shell, the improved The place is that the ventilation pipe is stretched into the water tank shell from the bottom of the water tank, and its upper end is higher than the inner nozzle of the overflow pipe.

The key of the utility model is exactly to change the original upper opening ventilation tube into the lower opening ventilation tube. Since the upper port of the air exchange pipe is above the inner nozzle of the overflow pipe in the water tank, the water tank can be filled with water smoothly and continue to overflow through the overflow pipe when the water is full; and the lower port of the air exchange pipe is set just in line with The characteristics of the hot air going up in the water tank are opposite, so the heat inside the water tank lost through the ventilation pipe can be greatly reduced, thereby improving the heat preservation effect of the water tank. The improvement of the heat preservation effect of the water tank is equivalent to the improvement of the working efficiency of the solar water heater and the improvement of the heat collection effect. The utility model effectively reduces the heat loss of water stored in the water tank, thereby prolonging the service time limit of the solar water heater.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Detailed ways

As shown in Figure 1, the new thermal insulation water tank is composed of a stainless steel liner 1 and a steel shell 3 made of a foam material insulation layer 2, etc. to form a water tank shell. Body, its basic structure can be identical with the structure of existing solar water heater water tank. Of course, an electric heating port and/or a sewage discharge port can also be provided correspondingly at the bottom of the water tank housing. In Fig. 1, a ventilation pipe 6 is pierced through the bottom of the water tank shell, and the upper part of the ventilation pipe 6 extends into the water tank shell, and its upper end is close to the top of the liner 1 and is about 1 cm higher than the inner nozzle of the overflow pipe 5. .

Overflow pipe 5 in the novel insulating water tank can be connected with water tank shell by traditional structure and mode, also can be juxtaposed with ventilation pipe 6, stretches in the water tank shell from the bottom of water tank, is more convenient to install like this. The upper port of the overflow pipe 5 is generally a flat opening, but it is preferably an inclined plane opening. Because of the overflow pipe 5 and the ventilation pipe 6 with flat openings, when the water pressure is high and the water supply is fast, there will be water injection to block the upper opening of the overflow pipe and the ventilation pipe, so that the inner tank will be broken due to the increase in pressure. Danger occurs, and the upper opening of the slope can well solve the problem of water injection blocking the upper opening, avoiding the damage of the water tank caused thereby. Therefore, in addition to the overflow pipe 5, the upper port of the ventilation pipe 6 should also be made in the form of an inclined plane opening.

The utility model also can be on the basis of above-mentioned various water tank structures, on the outer surface of the liner 1 of water tank housing, outsource one deck antifreeze heat insulation film again, to further improve the heat preservation effect of water tank. The antifreeze and heat insulation film can adopt the mature products available in the market.
