High-efficiency circulating water-heating blanket and cushion

Abstract

The invention relates to a water-heating blanket and cushion for using electricity to heat water to generate steam so as to push hot water to flow and transfer heat and particularly relates to an electric-heating water heating blanket and cushion. The electric-heating water heating blanket and cushion is characterized in that a blanket and cushion body is internally provided with a water channel; a heating container is combined with an electric heating device; a water storage tank is communicated with the heating container by a starting one-way valve; and the heating container is communicated with one end of the water channel in the blanket and the cushion body by a water-discharging connecting pipe, and the other end of the water channel is communicated with the water storage tank by a water-feeding connecting pipe so as to form a circulating path. The water-heating blanket and cushion also comprises a temperature-control device with a temperature sensing probe, wherein the temperature sensing probe is arranged in water in the heating container; the temperature change of the water is sensed by the temperature sensing probe; the temperature-control device is used for controlling a circuit of the electric heating device to be powered on and powered off, so that circulating heat transferring of hot water is realized.

Description

Technical field: [0001] The invention relates to a water-heated blanket and a mat for electrically heating water to generate steam to drive hot water to flow and transfer heat, in particular to an electric water-warming blanket and a mat. Background technique: [0002] The technology involved in this invention is Chinese patent: 201020215558.9, "Hot water circulation pad for heating". Heat, that is: heating with electricity (heating)—generating steam—power off—returning water (cooling down)—heating with electricity again to realize cyclic heat transfer. During this cycle, when the water returns, the cold water must first lower the temperature of the heating container or heating device, and then the temperature sensing device will sense the temperature drop, and then turn on the power, so that the power-on time is delayed and the cycle efficiency is reduced. In addition, in the cycle process, it is difficult to grasp the temperature from the start of electric heating and ste...

Problems solved by technology

During this cycle, when the water is returned, the cold water must first lower the temperature of the heating container or heating device, and then the temperature sensing device will sense the temperature drop, and then turn on the power, so that the power-on time is delayed and the cycle efficiency is reduced

In addition, in the cycle process, it is difficult to grasp the temperature from the start of electric heating and steam generation to the power off, because the temperature of the heating container shell or heating device and the temperature of steam generation does not have a constant value, which is related to power, heat conduction speed, induction The installation tightness of the heating element, the material of the heating container, and the capacity all have a great relationship. Therefore, it is difficult to determine and control the power-off temperature, which brings great trouble to the implementation of this product.
