Safe energy-saving electric heating blanket

Abstract

The invention provides a safe energy-saving electric heating blanket. The safe energy-saving electric heating blanket includes a blanket body, an insulating heating unit arranged in the blanket body, a plurality of temperature detection units evenly distributed in the blanket body, and a plurality of pressure sensing units evenly distributed outside the blanket body; each of the plurality of temperature detection units and the plurality of pressure sensing units periodically detects the temperature and the pressure around the unit, and sends acquired temperature information and pressure information to a controller; and the controller can turn on or turn off the heating unit to respond according to the received temperature information and the received pressure information.

Description

technical field [0001] The invention relates to the field of household electrical appliances, and more specifically, the invention relates to a safe and energy-saving electric heating blanket. Background technique [0002] Electric blanket, also known as electric mattress, is a contact electric heating appliance. It 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 it 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. It consumes less power, has adjustable temperature, is easy to use, and is widely used, and has a history of more than 100 years. [0003] At present, electric blankets have many disadvantages: First, most electric blankets only have two gears, and only a few electric blankets have multiple gears, ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many disadvantages in electric blankets: First, most electric blankets only have two gears, and only a few electric blankets have multiple gears, but both have limitations in temperature adjustment, and cannot be accurately controlled

Second, the work efficiency is low and the power consumption is large

Due to the low working efficiency, it takes about half an hour for the electric blanket to reach the ideal temperature

Although the high-end heating is faster, people often fall asleep in the high-end state. When they wake up, they find that the bed is very hot, which not only causes harm to the human body but also wastes electric energy.

The third is to produce electromagnetic radiation pollution, which will cause harm to the human body.

Four is not smart

When the user forgets to cut off the power supply of the electric blanket, the electric blanket will keep heating, which will not only cause a great waste of electric energy, but also cause a fire due to the accumulation of heat in serious cases; Urine, etc., the electric blanket cannot respond in time to cut off the power supply or send out an alarm
