Solar water heater exhaust pipe and solar water heater with exhaust pipe

Abstract

The invention relates to a solar water heater exhaust pipe and a solar water heater with the exhaust pipe. The exhaust pipe comprises an outer pipe and an inner pipe, wherein the lower end of the outer pipe is closed; the two sides on the lower part are provided with openings or meshes; the inner pipe is arranged in the outer pipe; the inner pipe is a reducer pipe, wherein the outside diameter size of the upper end is consistent with the inside diameter size of the outer pipe; and the lower end of the inner pipe is arranged at the position between the lower bottom surface and the openings or the meshes of the outer pipe. The solar water heater is provided with the exhaust pipe and an overflow pipe which is in the same structure as the exhaust pipe. The solar water heater exhaust pipe is simple to manufacture and low in cost, and can block air exchange inside and outside of a water tank, prevent the air in the tank and the air out of the tank from keeping communicating all the time, effectively reduce the dissipation of the temperature in the tank, achieve an instantaneous exhaust effect, and effectively reduce the blockage caused by steam condensing and icing at the opening of an outer exhaust pipe. The overflow pipe of the solar water heater can also be designed into the same structure as the exhaust pipe, and also can achieve remarkable effects of isolating air convection and reducing heat loss.

Description

technical field [0001] The invention relates to an exhaust pipe of a solar water heater and a solar water heater with the exhaust pipe. The exhaust pipe can reduce the exchange of hot air inside the water tank of the solar water heater and the outside air and reduce heat loss. Background technique [0002] At present, whether the exhaust pipe of the existing solar water heater is the upper exhaust or the lower exhaust, a straight-through pipe is used to connect the inside and outside of the water tank, so that the air inside the water tank and the air outside are kept connected at all times, and because Hot air always flows upward, so it is easy to cause heat loss. Although the existing utility model patent 200520087681.6 reduces heat loss by changing materials, it still does not effectively isolate the exchange of internal and external air. Therefore, the problem of reducing the heat loss caused by the exhaust pipe of the solar water heater needs to be solved urgently. C...
