Problems solved by technology

[0009]The disadvantage of the above solution is that the water heater must be powered on, and once the power is turned off, the anti-freezing effect cannot be achieved
[0010] In addition to the problem of freezing and blocking, the above-mentioned one-cycle pressurized solar water heater in the prior art also has the problem that the hot water circulation loop and the water circulation loop are not completely isolated, which affects the inner tank. The heating effect of stored water, at the same time, when using water, the incoming cold water may flow into the outlet pipe, causing the pipe to freeze and block

Embodiment Construction

[0031] Please see figure 2 , Is a schematic structural diagram of the first embodiment of the present invention. This example is in figure 1 Based on the stated prior art, several improvements are made. figure 2 Middle and figure 1 Same part use figure 1 The label shows. The following combination figure 2 The structure of the solar water heater is described.

[0032] The main components of the solar water heater include an inner tank 102, a heat collector 104, and other auxiliary parts. The area ratio of the heat collector 104 to the inner tank 102 requires the heat collector 104 to ensure that it can take a bath on the same day as much as possible. The inner tank 102 is the innermost water storage part of the water tank 101, and the water tank 101 also includes an outer shell located at the outermost part, and an insulation layer between the outer shell and the inner tank. The heat collector 104 may adopt a flat plate type heat collector and a heat pipe type heat collecto...

Abstract

The present invention discloses a primary circulating solar water heater. It includes internal container and collector, the lower portion of said internal container is connected with water inlet of collector by means of water outlet pipe, the water outlet of collector is connected with upper portion of said internal container by means of water-returning pipe, on the pipeline of water outlet pipe a water pump is mounted, the lower portion of said internal container is connected with a water inlet pipe, and said water inlet pipe is connected with external water source. The position of the described collector is higher than the described internal container, on the pipeline of water outlet pipe between the described water pump and the described internal container an electromagnetic valve is mounted. Said invention also provides the working principle of said primary circulating solar water heater and its concrete operation method.

Description

technical field [0001] The invention relates to a water heater, in particular to a primary cycle solar water heater. Background technique [0002] Extensive utilization of renewable resources such as wind energy and solar energy is an important part of building a conservation-minded society, and solar water heaters are an important way to utilize solar energy. [0003] Please see figure 1 , which shows a schematic diagram of the piping structure of a general-purpose primary cycle pressurized solar water heater in the prior art. The solar water heater includes a water tank 101, the water tank 101 has an inner tank 102 for directly storing water, the lower part of the inner tank 102 is connected to the water inlet of the heat collector 104 through a water outlet pipe 107, and the water outlet of the heat collector 104 is connected to the inner tank 102 through a return pipe 108 . A water pump 103 is installed near the outlet of the water tank 101 in the water outlet pipe 10...
