Problems solved by technology
This traditional structure has the following disadvantages. First, in order to ensure that the cold water in the water storage tank can flow to the heat collector, the water storage tank must be designed to be open, that is, it must be the same as the atmosphere, which leads to easy loss of heat in the water storage tank. The heat preservation effect is not good, and the heating speed is slow; secondly, when using, the user needs to turn on the cold water switch first, fill the water storage tank, and then wait for the water in the water storage tank to be completely heated before using it, and wait until the hot water in the water storage tank After it is used up, cold water can be injected into the water storage tank again, and then heat exchange with the heat collector, which leads to the discontinuity of the hot water used by the user, and the heating time is relatively long

Embodiment Construction
[0018] like Figure 1 to Figure 6 As shown, a solar water heater includes a bracket 1, the bracket is vertically installed on the ground or a building, and a hot water storage tank 2 is installed on the bracket 1, and the hot water storage tank 2 includes an inner tank 3, which is covered inside The thermal insulation layer 4 of the outer layer of the bladder 3 and the outer shell 5 wrapping the thermal insulation layer 4, the inner bladder 3 is provided with a water inlet 301 that can be connected to a cold water source and a water outlet 302 that supplies hot water to the user. The solar water heater also includes a bracket fixed to 1. A collector 6 that can contain fluid working medium, receive solar energy and heat the fluid working medium. The collector 6 is installed obliquely below the hot water storage tank 2. The accommodating cavity 7 containing the fluid working medium flowing from the heat collector 6, the hot water storage tank 2 is also provided with a heat colle...

The invention discloses a solar water heater which comprises a bracket, wherein the bracket is equipped with a hot water storage tank which comprises an inner tank, a heat preservation layer covering the outer layer of the inner tank, and a shell covering the heat preservation layer, the inner tank is provided with water inlet communicated with a cold water source and a water outlet supplying hot water to users. The solar water heater is characterized by also comprising a heat collector, which is fixed on the bracket and capable of containing a fluid working medium, receiving solar energy and heating the fluid working medium, wherein the heat collector is obliquely installed below the hot water storage tank, an accommodating cavity capable of containing the fluid working medium from the heat collector is arranged between the inner tank and the heat preservation layer, and a working medium water inlet and working medium water outlet, which can communicate the heat collector with the accommodating cavity so that the fluid working medium can circulate and flow between the heat collector and the accommodating cavity, are also arranged on the hot water storage tank. The solar water heater has the advantages of fast heating speed and good heat preservation effect and can continuously supply hot water.
Description
【Technical field】 [0001] The present invention relates to a solar water heater. 【Background technique】 [0002] With the development of society, the global energy is becoming increasingly scarce. As a new energy and environmental protection product, solar water heaters are more and more used in thousands of households. It absorbs solar energy and converts solar energy into heat energy, thereby heating cold water and bringing people a It's convenient and affordable. Existing solar water heaters generally have a storage tank connected to a collector. When the cold water in the storage tank is full, the valve is opened, and the cold water flows into the collector for heat exchange, and the heated hot water is sent to the collector. It flows back up to the water storage tank, and then is discharged through the water outlet for use by users. This traditional structure has the following drawbacks. First, in order to ensure that the cold water in the water storage tank can flow t...
