Device for pipe evacuation and water consumption control of solar water heater hollow housing body

Abstract

The invention discloses a device with the evacuation and the water usage of solar water heater hollow box body pipelines controllable, which is characterized in that: the device comprises: 1, 2, 3, 4, 5 and 6 normal opened and closed electromagnetic valves, an assembly flash logic processor chip, a hollow interlayer foam heat preservation box body and a pipeline emptier body. The electric parts are controlled by the assembly flash logic processor chip arranged on the circuit board; the pipeline emptier body is positioned in an emptier chamber of the hollow interlayer foam heat preservation box body; the 2, 3, 4, 5 and 6 normal opened and closed electromagnetic valves are arranged at the proper position indoor, which, during utilizing, are able to watering both manually and automatically; hot water are available mostly; water in the pipeline can be automatically empty after watering and using the hot water, which enables the device to store more hot water in the box body. The invention is characterized by rational structure, simple operation and more humanization.

Description

Technical field [0001] The invention relates to the structure of a solar water heater, and more specifically, it is a device for the emptying of hollow tank pipes of the solar water heater and the controllable water consumption. Background technique [0002] At present, the existing solar water heaters do not have pipeline emptying devices and solar water heaters that integrate water consumption, hot water diversion automatic control, and hollow sandwich foam insulation box. In winter in cold regions, the outdoor pipes of the existing solar water heaters still need to be heated. If they are folded, they will freeze. This wastes electric energy, and there is still a lot of cold water in the pipes, so that the heat in the pipes is lost again and again. The thermal insulation performance of the body is not good, and it is not suitable for use in cold areas. [0003] Chinese patent ZL02288977.9 discloses a "solar water heater pipe emptying device". Its technical solution is to instal...

Problems solved by technology

[0006] (1) It is the pipe emptying manual push-type air cylinder of the solar water heater pipe emptying device. Because the pipe is too long, it is easy to cause blockage. At the same time, if you want to use water in multiple places, it is not easy to install the emptying pipe

[0007] (2) It is very complicated to operate each item manually in batches for filling the solar water heater and emptying the pipeline, and it is easy to make wrong judgments, and it is impossible to realize water use in many places such as kitchens and bathrooms. Because the faucet is normally open, only Being able to install a faucet greatly reduces the utilization rate and fails to meet the humanized standard

[0008] (3) It is the hollow square layer and the partition in the new insulation box of the solar water heater. In the design, the hollow square layer and the round hole set by the partition, the vacuum heat collecting tube passes through the round hole, because the round hole and the round hole If the distance between the holes is too small, it is not easy to bond firmly, and it is easy to cause air leakage, thus losing the hollow effect
