a hydrothermal blanket

Abstract

The invention provides a hydrothermal blanket, which comprises an upper soft fabric, a heating layer, lower anti-slip cloth, a heating water bag, a heater, a controller and a warm water pipe. The upper soft fabric and the lower anti-slip cloth are sewn together, and the heating layer is sandwiched between the upper soft fabric and the lower anti-slip cloth. The heating water bag is mounted on theleft side of the heating layer, the heater is mounted in the heating water bag, the controller is arranged outside the hydrothermal blanket and connected with the heater, the warm water pipe is laid in a U shape at equal intervals on the heating layer, and two ports of the warm water pipe are connected with two ends of the heating water bag respectively. The hydrothermal blanket has advantages that by arrangement of the heater in the hydrothermal blanket, the thickness of the hydrothermal blanket is not increased, and extra occupying of a bedroom space is avoided; when the water pipe in the hydrothermal blanket is partially pressed and blocked, the hydrothermal blanket can still be used normally without potential safety risks.

Description

technical field [0001] The invention relates to household appliances, in particular to a water heating blanket. Background technique [0002] In the cold winter, the common way of heating the bed is heating the electric blanket. Although the electric blanket can keep warm, but the electric blanket will keep the capillaries in a state of dilation, the water and salt in the body will be lost obviously, dry mouth, sore throat, nostril bleeding, dry skin and constipation, etc., and there are also electric heating wires Easy leakage and aging problems. Thereby a kind of hydrothermal blanket improved based on various disadvantages and unsafety of electric blanket appeared on the market. [0003] The Chinese patent No. CN100441123C discloses a "water heating blanket", which includes a hose, a connecting pipe, a pad, an expansion device, a start check valve, an end check valve, and an electric heating element. [0004] In the hydrothermal blanket involved in the above invention, ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the defects in the prior art, the hydrothermal blanket provided by the present invention solves the problem that the existing hydrothermal blanket needs to heat the water through an external heating device before passing the hot water into the hydrothermal blanket for circulation, and the volume of the external heating device Larger, take up bedroom space issues
