Hot water circular cushion for warming

Abstract

The invention relates to a hot water circular cushion for warming by using water vapor to push water to circularly flow for heat transmission, which comprises a hose, a cushion body, an expanding water tank, a start holding valve, tail-end holding valves, an electrical heating element and a hot water pipe. The hot water pipe is combined with the electrical heating element, and the flexible pipe is arranged in the cushion body. The hot water circular cushion for warming also comprises a vapor pipe and an exhaust connecting hose. One end of the hot water pipe is connected with one end of the vapor pipe, the other end of the vapor pipe is connected with one end of the hose, the other end of the hose is connected with one end of the exhaust connecting hose, the other end of the exhaust connecting hose is connected with one end of the expanding water tank, and the other end of the expanding water tank is connected with the other end of the hot water pipe through a connecting pipe to form a circular passage. The start holding valve is arranged on the connecting pipe, the tail-end holding valves are arranged on the optional positions of the hose and the exhaust connecting hose, and the direction of the start holding valve and the directions of the tail-end holding valves are the same. The volume in the hot water pipe is matched with the volume in the vapor pipe, and an inlet connecting hose is added between the vapor pipe and the hose. The temperature of the water entering the hose in the cushion body is not high by using the structure, and the water is very comfortable to use.

Description

technical field [0001] The invention relates to a hot water circulation pad for heating that promotes water circulation and heat transfer with water vapor, including mattresses, sofa pads, floor pads, seat pads, foot pads, and waist pads. Background technique [0002] I once filed a water heating blanket with the application number 200510129300.0, publication number CN1806723A, and publication date of July 26, 2006 to the Chinese Patent Office. There is a hot water pipe, which is combined with the electric heating element; the hot water pipe and the expansion device are connected in series through the flexible pipe to form a circulation path; the expansion device and the hot water pipe The one-way valves in the same direction are respectively arranged on the flexible pipes connected at both ends; the flexible pipes are arranged in the cushion body. The above-mentioned patent application does not give the relationship between the volume of the hot water pipe and the inner vo...

Problems solved by technology

The above-mentioned patent application does not give the relationship between the volume of the hot water pipe and the inner volume of the hose directly connected to the hot water pipe outside the pad. It is possible that water vapor enters the part of the hose inside the pad and the temperature of the pad is too high.
