Multifunctional water inlet and outlet device

Abstract

The invention discloses a multifunctional water inlet and outlet device, comprising a water tank and a water inlet and outlet pipe; wherein the water inlet and outlet pipe is in an inversed L shape and is arranged in the water tank from lateral upside, and the middle of the water inlet and outlet pipe is provided with a hot water replacement opening. Water pipe evacuation antifreezing can be realized in winter, and the part below the hot water replacement opening is used for hot water replacement. Hot water automatic flow above the hot water replacement opening can be realized in non-winter seasons, and the part below the hot water replacement opening can be used for hot water replacement. The multifunctional water inlet and outlet device of the invention can overcome the defects in the prior art, has the characteristics of convenience, safety, low carbon, energy conservation, good evacuation antifreezing effect and high hot water replacement rate and is applicable to different solar water heaters used in different environments.

Description

technical field [0001] The invention relates to a multifunctional water inlet and outlet device, which belongs to the technical field of solar water heaters. Background technique [0002] The water inlet and outlet pipes of the existing solar water heater water tank are mostly placed into the water tank in a horizontal or upward manner, and its function is single, without functions such as emptying, antifreezing, and hot water replacement. Even if the inlet and outlet pipes have the functions of emptying antifreeze and hot water replacement, because the hot water replacement method is to add cold water above the hot water layer in the horizontal direction of the inlet and outlet pipes, during the process of adding cold water, the cold and hot water are easy to mix and cool down, resulting in hot water. The replacement rate is reduced. After emptying in winter, the remaining water in the water tank will expand due to heating and the water level will rise, causing the inlet an...

Problems solved by technology

[0002] The water inlet and outlet pipes of the existing solar water heater water tank are mostly placed in the water tank horizontally or upwardly, and its function is single, without functions such as emptying, antifreezing, hot water replacement, etc.

Even if the inlet and outlet pipes have the functions of emptying antifreeze and hot water replacement, because the hot water replacement method is to add cold water above the hot water layer in the horizontal direction of the inlet and outlet pipes, during the process of adding cold water, the cold and hot water are easy to mix and cool down, resulting in hot water. The replacement rate is reduced. After emptying in winter, the remaining water in the water tank will expand due to heating and the water level will rise, causing the water inlet and outlet pipes to overflow, which will easily lead to freezing and blocking of the upper and lower water pipes of the solar water heater.
