Description

Technical Field

[0001] The utility model relates to the field of solar water heaters, in particular to a filtering water tank of a solar water heater. Background Art

[0002] Solar water heaters are usually composed of collectors, water tanks and pipes. The collector is the core component of a solar water heater. It is generally composed of a series of vacuum tubes or flat plates. The surface of these tubes or plates is coated with a selective absorption coating, which can efficiently absorb solar radiation.

[0003] When sunlight shines on the collector, the coating absorbs solar energy and converts it into heat energy, raising the water temperature in the collector. The collector and the water tank are connected by a pipe, and water circulates in the pipe. The heated water naturally rises into the water tank, while cold water enters the collector from the bottom of the water tank for heating.

[0004] The water tank usually has an insulation layer to reduce heat loss and keep the water at a higher temperature. Some solar water heaters are also equipped with auxiliary heating devices, such as electric heaters or gas water heaters, to provide additional heating when solar energy is insufficient or the weather is bad.

[0005] When the water tank is replenished, the water contains a large amount of impurities. The water containing a large amount of impurities enters the collector tube of the solar water heater, causing a large amount of scale to form inside the collector tube, which will cause the following problems:

[0006] 1. Reduced thermal efficiency: The presence of scale will hinder the transfer of heat and reduce the heat conduction efficiency inside the collector tube; this means that the solar water heater takes longer to heat the water, resulting in insufficient hot water supply;

[0007] 2. Increased energy loss: The thermal conductivity of scale is low, which will cause the heat inside the collector tube to be unable to be effectively transferred to the water, resulting in partial energy loss; this will reduce the overall efficiency of the solar water heater and prevent it from fully utilizing solar energy;

[0008] 3. Shorten the life of the equipment: The accumulation of scale may cause corrosion and damage to the inside of the collector tube; in the long run, this may cause leakage or failure of the collector tube, shortening the service life of the solar water heater; Utility Model Content

[0009] The purpose of the utility model is to provide a solar water heater filtering water tank to solve the defects mentioned in the above background technology.

[0010] To achieve the above object, a solar water heater filtering water tank is provided, comprising a water tank body, an upper cover is screwed on the top of the water tank body, a water supply pipe is installed on the left side of the upper cover surface, a hot water inlet pipe is installed on the right side of the upper cover surface, and a hot water discharge pipe is installed at the bottom of the water tank body, and valves are installed on the hot water discharge pipe, the hot water inlet pipe and the water supply pipe; a thermal insulation lining is fixedly installed on the inner wall of the water tank body; a fixing frame is fixedly installed at the bottom of the water tank body;

[0011] A positioning seat is fixedly installed at the bottom of the upper cover, and a mounting end is arranged on the upper part of the water tank body, and the mounting end is adapted to the size of the positioning seat. A fixing seat is installed on the upper inner side of the water tank body, and a filter is installed on the lower inner side of the fixing seat. A water guide plate is installed on the upper side of the filter, and the water guide plate is fixedly connected to the bottom of the water supply pipe.
