Description

Technical Field

[0001] The utility model relates to the field of solar water heaters, in particular to an antifreeze type solar water heater. Background Art

[0002] A solar water heater is a device that uses solar energy to heat water to supply household hot water. The comparative document CN201803480 U proposes a water heater. The double-opening double-pass pipe design also makes it particularly easy to clean the collector tube. Inlet and outlet holes are set on the auxiliary water tank so that the water in the water heater can be fully utilized to save energy. The problem with the above technology is that in cold weather, the solar water heater is very likely to cause the surface temperature of the vacuum tube to drop during use, thereby reducing the heat collection efficiency and the ability to produce hot water. At the same time, in cold weather, the water or moisture inside the vacuum tube is very likely to freeze, thereby hindering normal heat transfer. At the same time, when the water source is not in use, the water source stored in the solar water heater requires heat energy to be continuously heated, resulting in a large amount of heat energy waste. Utility Model Content

[0003] The purpose of the utility model is to solve the following problems existing in the prior art: in cold weather conditions, the solar water heater is very likely to cause the surface temperature of the vacuum tube to drop during use, thereby reducing the heat collection efficiency and the ability to produce hot water; at the same time, in cold weather conditions, the water or moisture inside the vacuum tube is very likely to freeze, thereby hindering normal heat transfer; at the same time, when the water source is not in use, the water source stored in the solar water heater requires thermal energy for uninterrupted heating, resulting in a large amount of thermal energy waste.

[0004] In order to solve the problems existing in the prior art, the utility model provides an antifreeze type solar water heater, including a mounting frame, a heat collecting plate and a water tank, wherein a support seat is provided at the bottom of the mounting frame, a heat collecting plate is provided on the inner side of the mounting frame, a plurality of groups of vacuum tubes are provided equidistantly inside the heat collecting plate, three groups of heating tubes are provided at the bottom of the vacuum tubes inside the heat collecting plate, a water tank is provided on the top of the mounting frame, an inner liner is provided inside the water tank, and a spiral tube is provided around the outer side of the inner liner.

[0005] Furthermore, a rubber anti-skid pad is provided at the bottom of the support base, and the support base can support the entire device.

[0006] Furthermore, the heating tube is laid flat on the bottom of the vacuum tube in an S shape, and the heating tube can heat the vacuum tube.

[0007] Furthermore, a water outlet is provided on the left side of the back side of the water tank, and a water inlet is provided on the right side of the inner surface of the water tank. The water outlet is used to output the water source, and the water inlet is used to transfer the water source to the inner tank.

[0008] Furthermore, a temperature sensor is provided inside the inner tank, and the inner tank is used to store water.

[0009] Furthermore, the spiral tube is spirally wound around the outer side of the inner pot, and the input end of the spiral tube is connected to the inner pot. The spiral tube is used to transfer the heat energy of the hot water to the inner pot, thereby reusing the heat energy.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model can evenly heat the vacuum tube under certain conditions through the heating tube, thereby avoiding the freezing of water sources in cold weather, ensuring that the solar water heater can still work normally in winter or cold areas, extending the use season of the solar water heater, and making the solar water heater more suitable for coping with various climatic conditions.

[0012] The utility model transmits hot water in a spiral manner through a spiral tube, and at the same time conducts the heat generated by the hot water to the inner tank, thereby improving the heat transfer efficiency, helping to use thermal energy to quickly heat the water source stored in the inner tank during the subsequent heating process of the water source, thereby accelerating the heating efficiency of the solar water heater for the water source, and at the same time, the water source can be kept warm when the water source is not in use, which helps to reduce the energy consumption of the solar water heater.
