When power is applied, the program of FIG. 2 stored in the memory 50 is executed by the microcontroller 30 to start the operation of the ion air generating bed according to the embodiment of the present invention.

When the operation starts, the microcontroller 30 initializes various memory variables stored in the memory 50.

The analog / digital converter 20 converts the analog signal input from the sensor unit 10 into a digital signal and outputs the analog signal to the microcontroller 30.

The microcontroller 30 determines whether the internal temperature is smaller than the set temperature (external temperature + α), and when the internal temperature is smaller than the set temperature, outputs the heater driving signal to the driver 60 to drive the heater 100. When the internal temperature is not smaller than the set temperature, the driving of the heater 100 is stopped by outputting the heater driving stop signal to the driver 60.

Chemically, ions refer to fewer or more electrons orbiting the outermost orbit of an atom by ionization, and are caused by ionization of a single atom or compound. None of them are electrically neutral, and the lack of electrons is electrostatic, so the cation (+) and the excess electrons are negatively charged, so they are called anions (-).

As such, negative ions are generic terms for all negative charge values ranging from extremely fine atoms or electrons in general air to suspended solids in the form of particles. When inhaled by the human body, it cleans the blood, stabilizes the nervous system, and promotes metabolism of cells, so it is known to be a vitamin of air because it has many beneficial effects such as fatigue recovery and appetite.

During natural phenomena, you may often find yourself feeling refreshed when you are near waterfalls, by fountains in parks, after showers, on the beach, in the forest, etc., which are oxygen ions that have negative ions due to natural phenomena. This is because it occurs in large quantities.

The above negative ions can be artificially obtained by gas discharge. Conventionally, an air purifier for purifying air beneficial to the human body by generating negative ions through an anion generator using artificial gas discharge has been widely marketed.

An air hole is drilled in the mattress 90 so that the air of anion (-) component transmitted from the compressor 80 is supplied to the human body through the air hole.
