Heat energy water circulation system

Abstract

The invention relates to a heat energy water circulation system that utilizes electrical heating of water to generate steam to drive water flow, and especially relates to the heat energy water circulation system of electrothermal water heating blankets, cushions, water heating beds, water heating bed boards, water heating brick beds, water heating brick bed boards, water heating bedding, radiators, heaters and the like. The invention aims to provide the heat energy water circulation system that has a good water return effect and can well supply water to a heating cylinder. A first scheme involved in the invention is characterized in that: the upper end of a fluid heating pipe is communicated with a steam chamber, and the lower end of the fluid heating pipe is connected to the steam chamber through a delayed water supply device. The communication part of the upper end of the fluid heating pipe and the steam chamber is higher than the connection part of the fluid heating pipe lower end and the steam chamber that are connected through the delayed water supply device. The fluid heating pipe is arranged obliquely. A second scheme involved in the invention is characterized in that: the heating cylinder is communicated with the steam chamber and is also in connection with the steam chamber through the delayed water supply device, and the communication part of the heating cylinder and the steam chamber is higher than the connection part of the heating cylinder and the steam chamber that are connected by the delayed water supply device.

Description

Technical field: [0001] The present invention relates to a kind of heat energy water cycle system that electric heating water generates steam to push water to flow, especially relates to electric heating blanket, pad (including mattress, seat pad, ground pad, sofa pad, foot pad, waist pad, pillow pad, thermotherapy pad etc.), water heating bed, water heating bed board, water heating kang, water heating kang board, water heating bedding, radiator and heater etc. heat energy water circulation system. Background technique: [0002] Chinese patent 201020215558.9 discloses a hot water circulation pad for heating. The technical solution is: the heating cylinder is connected to one end of the steam pipe, the other end of the steam pipe is connected to the end of the water outlet connecting hose, the other end of the water outlet connecting hose is connected to one end of the water channel, and the other end of the water channel is connected to the water inlet connecting hose One e...

Problems solved by technology

[0003] However, the above schemes have been found to have deficiencies through practice. During work, when the heating cylinder or the steam chamber returns water under the condition of continuous power cycle without turning off the power supply, the water immediately enters the heating cylinder to generate water vapor expansion, causing the heating cylinder or The steam chamber cannot fully return water or only a small amount of water can return, resulting in a decrease in the overall circulation effect
