Electric heating blanket controller, single temperature control electric heating blanket, double temperature control electric heating blanket and control method

Abstract

The invention discloses an electric heating blanket controller which at least comprises one temperature zone unit; each temperature zone unit at least comprises one heat-generating body, a temperaturecontrol circuit used for controlling each corresponding heat-generating body to heat up to a specified temperature, and a human body induction apparatus used for triggering on-off of each corresponding temperature control circuit; the human body induction apparatus triggers a corresponding temperature control circuit only at a human body position so as to control a corresponding heat-generating body to generate heat. The invention also discloses a single temperature control electric heating blanket, a double temperature control electric heating blanket and a control method that can be appliedto the electric heating blanket controller. The electric heating blanket controller, the single temperature control electric heating blanket, the double temperature control electric heating blanket and the control method are advantageous in that only at the human body position can the corresponding temperature control circuit be triggered so as to control the corresponding heat-generating body togenerate heat, heat energy waste of a whole blanket surface can be prevented, electric connection with the temperature control circuit can be automatically broken when a human body leaves, the heat-generating body can be controlled not to generate heat, and energy conservation and environment protection effects can be exerted.

Description

technical field [0001] The invention relates to the technical field of electric blankets, in particular to an electric blanket controller, a single temperature control electric blanket, a double temperature control electric blanket and a control method. Background technique [0002] Electric blanket is a kind of contact electric heating appliance. It emits heat through the insulating electric heating element placed on the blanket surface when it is energized, so as to supply heat when it contacts with the human body. Due to the advantages of low power consumption and economical application of the electric blanket, It is very popular in autumn and winter in the northern region. [0003] However, due to problems such as the quality of electric blankets, facts such as fires caused by forgetting to turn off the power or being unable to automatically turn off the power often occur, which brings huge losses to people's lives and properties. Existing setting temperature controller...

Problems solved by technology

However, since the temperature controller only detects the temperature of certain fixed-point positions on the blanket surface, and the human body does not lie on the fixed-point positions every time, the temperature detection is inaccurate

At the same time, due to the uncertain position of the human body on the blanket surface, the existing electric blankets are all electrified on the entire blanket surface, that is, when the electricity is turned on, the electric heating elements placed on the entire blanket surface generate heat, not just at the contact between the human body and the blanket surface. , leading to a large waste of heat energy, and once the human body leaves the blanket surface, the temperature controller of the electric blanket cannot immediately cut off the power, and the temperature controller still needs to detect that the temperature of the blanket surface at a fixed point is overheated before powering off or keeping warm, resulting in waste of electricity
