Embodiment

[0034] Because the temperature inside the bedding is not only related to the power of the electric blanket, but also related to the ambient temperature and the thickness of the bedding; therefore, in this embodiment, the following means are used to establish the conversion relationship between the power percentage and the temperature inside the bedding:

[0035] First, select multiple existing electric blankets, and connect external controllers in series in a standard room;

[0036] Then, under different ambient temperatures, different bedding thicknesses, and different power percentages, temperature detectors or thermocouples are used to detect the corresponding internal temperature of the bedding (in order to be more accurate, the average temperature can be taken); the "different power percentage" here can be adjusted according to The duty cycle of the PWM wave of the external controller is used to control the power percentage output of the electric blanket;

[0037] Then, b...

Abstract

The invention relates to an electric blanket temperature control technology, and provides a method for adjusting the heating temperature of an electric blanket based on an external controller aiming at the current common electric blanket, so as to dynamically control the heating temperature of the electric blanket and improve the sleeping comfort of a user. A sleep curve program and a power control curve program are preset in an external controller; the power control curve at least comprises a mapping relation between the control power and the temperature in the bedding; the control method comprises the steps that the external controller controls the power of the electric blanket according to the sleep curve in combination with the power control curve, and therefore the heating temperature of the electric blanket in different sleep stages is adjusted.

Description

technical field [0001] The invention relates to the temperature control technology of electric heating blankets, in particular to a method for adjusting the heating temperature of electric heating blankets based on an external controller, and is especially suitable for improving the use comfort of existing common electric heating blankets. Background technique [0002] An electric blanket is a contact electric heating appliance, which sews a special electric heating element into the blanket and emits heat when it is energized. It is mainly used to increase the temperature inside the bedding when people are sleeping to achieve the purpose of heating. Because the electric blanket has the characteristics of low power consumption and convenient use, it is the main way for the elderly to sleep on the mattress in winter. [0003] Modern medicine believes that sleep generally includes non-rapid eye movement (non-rapid eye movement, NREM) sleep and rapid eye movement (rapid eye mov...
