Hot water circulating cushion for heating

Abstract

The invention relates to a hot water circulating cushion for heating, which utilizes water vapor to push water to circularly flow to transfer heat. The hot water circulating cushion is characterized in that: a heating barrel is communicated with one end of a steam pipe, and the other end of the steam pipe is communicated with one end of a water outlet connecting hose; the other end of the water outlet connecting hose is communicated with one end of a water channel; the other end of the water channel is communicated with a water inlet connecting hose; the other end of the water inlet connecting hose is communicated with an expansion tank which is communicated with one end of a water return connecting pipe; the other end of the water return connecting pipe is communicated with the heating barrel; and a start check valve is arranged at any position of the water return connecting pipe between the expansion tank and the heating barrel to form a circulating passage. The check valve is not arranged on a channel formed by the steam pipe, the water outlet connecting hose, the water channel, and the water inlet connecting hose. The channel is arranged between the heating barrel and the expansion tank. Due to the structure, the hot water circularly transfers heat, so the hot water circulating cushion is simple in structure, stable in performance and is easy to promote and popularize.

Description

technical field [0001] The invention relates to a hot water circulation pad for heating which utilizes water vapor to promote water circulation and heat transfer, including mattresses, sofa pads, floor pads, seat pads, foot pads and waist pads. Background technique [0002] In the past, hot water circulation pads used water pumps to circulate hot water to transfer heat. The noise of the water pumps, short service life, and high cost hindered the promotion and popularization of this product. Later, I proposed to the Chinese Patent Office that the patent number is 200510129300.0, the publication number is CN1806723A, and the publication date is 2006.7.26, and the application number is 200810093136.6. , the use of water vapor to promote water flow and heat transfer solves this problem. The technical schemes of the above two patents all include these two parts and components of a start check valve and an end check valve. During its work and operation, when the water is returne...
