Hot water circulation pad for heating

Abstract

The invention relates to a hot-water circulation pad for heating, which utilizes water vapor to drive water to flow circularly for heat transfer. The hot-water circulation pad for heating has the characteristics of no water hammer and no noise. The hot-water circulation pad for heating 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 which is communicated with one end of a water inlet connecting hose, and the other end of the water inlet connecting hose is communicated with an expansion water tank; and the expansion water tank is further communicated with one end of a backwater connecting pipe, the other end of which is communicated with the heating barrel, a start check valve is arranged at any positions of the backwater connecting pipe between the expansion water tank and the heating barrel, an end check valve is arranged at any positions of the steam pipe, the water outlet connecting hose, the water channel and the water inlet connecting hose, the direction of the end check valve is consistent with the start check valve, a steam chamber is arranged and is communicated with the heating barrel and the steam pipe.

Description

[0001] This application is a divisional application based on the patent application with the Chinese patent application number: 201010190408.1 and the filing date: 2010.05.22 and the name: hot water circulation pad for heating. technical field [0002] 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, waist pads and the like. Background technique [0003] 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...
