A temperature-controlled electric blanket for heating by area and weight

Abstract

The invention discloses a temperature control electric blanket capable of heating according to areas and weights. The electric blanket is divided into a plurality of heating areas, a heating wire witha pressure detection circuit and a control circuit are arranged in each area, if the pressure value detected by the pressure detection circuit in a certain area is smaller than a set value, it is considered that no person lies on the electric blanket, and the heating wire Rf1 in the area cannot be powered on to work; if the pressure value detected by the pressure detection circuit in a certain area is greater than a set value and is kept for more than a period of time, it is considered that someone lies on the pressure detection circuit, the heating wire Rf1 in the area performs heating at full power, and when the temperature reaches the set value, the heating wire Rf1 is converted into half power for heat preservation, so that electric energy is saved; and, in addition, people with different weights sleep on the electric blanket, the heating speeds of the electric blanket are different, the larger the weight is, the higher the heating speed of the electric blanket is. The electric blanket can be heated in a regional and weight-divided mode according to pressure signals, the heating temperature can be automatically controlled, use is convenient, and electric energy is saved.

Description

technical field [0001] The invention relates to a temperature-controlled electric blanket, in particular to a temperature-controlled electric blanket heated by regions and weights, and belongs to the technical field of electric blanket heating. Background technique [0002] Electric blanket, also known as electric mattress, is a contact electric heating appliance, which weaves or sews a special cable-type electric heating element with a standard insulation performance into the blanket in the shape of a snake, and emits heat when it is energized; It is mainly used to increase the temperature in the quilt when people sleep to achieve the purpose of heating, and it can also be used for dehumidification and dehumidification of quilt. [0003] The weather is cold in winter, and many elderly people like to use electric blankets for heating. Traditional electric blankets use the uniform wiring method, but in actual use, it is found that there are some places where people's bodies ...

AI Technical Summary

Problems solved by technology

Traditional electric blankets use the uniform wiring method, but in actual use, it is found that there are some places where people's bodies are rarely touched. At this time, if the area is still hot, it is a bit of a waste of electricity; If the uniform wiring method is used, the heat is insufficient. In addition, although the electric blanket has a temperature adjustment switch, once it is turned on, it will be heated according to the heating power. This will cause the temperature of the bed to be too high when using the high temperature file; The temperature of the quilt will not come up for a long time; if you use the high temperature first, and then use the low temperature after a period of time, it is not convenient to use
