KR20030006447A - Heating and Steamer for water with microwave - Google Patents

Abstract

PURPOSE: A heating and steam device using microwaves are provided to heat water and generate steam by using the microwaves. CONSTITUTION: An RF(Radio Frequency) oscillation portion(6) generates microwaves. A microwave output portion(61) is used for inducing microwaves to a tank including water through a waveguide or an RF connector. A particular coating material(21) is coated on an inner face of the tank in order to prevent outflow of the microwaves. A resonant phenomenon is generated by the microwaves absorbed into the wafer of the tank. The steam is generated from the water by using the resonant phenomenon. The generated steam is discharged to a steam discharge hole(1). A temperature/pressure control portion(35) is operated by a thermal sensor(31) or a pressure sensor(32). A flux control portion is operated according to a sense signal of a flux sensor portion(51) in order to operate a solenoid valve(53).

Description

Heater using microwave, steamer {Heating and Steamer for water with microwave}

The present invention is a device for activating the natural frequency of water molecules using microwaves to generate frictional heat instantaneously to boil water and to generate hot steam to spew out. Current heat generators and steam generators generate heat from heating wires by using heating wires, or heat from heating wires using fuel, and the heat generated is transferred by heat conductors, and then heats through containers containing water. Since it is transferred to the water through the heating wire and the heat conduction light, the heat is indirectly transferred to the water after several steps, so heat loss occurs, which takes a lot of time to heat the water.

The present invention not only reduces the power loss due to heat conduction by directly injecting microwaves into the water to generate water, but also makes it easy to use in miniaturization, speed, and lightness, and can also be made portable for use in rechargeable batteries or automobiles. have.

Accordingly, an object of the present invention is to provide a convenient and low maintenance cost with speed, low power, small size, light weight, and the like.

Figure is a schematic diagram of the exothermic, steam using a microwave according to a preferred embodiment of the present invention.

The configuration of the present invention is a microwave output unit for generating a microwave by oscillating in the high frequency oscillation unit (6) and directing the microwaves obtained by directing the microwaves to water through the waveguide or the high frequency connector into the container (2) containing water ( 61).

In addition, the inside of the container is a special coating (21) to prevent microwaves from leaking out.

When the microwaves are exposed to water molecules by the device, the water molecules absorb the microwaves and cause a resonant phenomenon to rotate violently. Therefore, the water molecules generate heat by using frictional heat generated by numerous water molecules colliding with each other very quickly. It is a device for generating steam by using the steam discharge port (1) to release steam (vapor).

The device also has the advantage of not heating without water.

In this device, the microwave output unit 61 shown in Fig. 2 is put on the surface of the water, and when the mi-propa is fired on the surface, only the top part of the water generates instantaneous heat, and steam is generated in a short time. Water vapor can be generated to reduce energy loss.

This device is designed to be able to control when the temperature or pressure in the container 2 rises more than a certain level by a double stabilizer.

In other words, if the temperature or pressure rises by a temperature sensor 31 or pressure sensor 32 or more, the temperature / pressure control unit 35 operates to suppress the generation of microwaves, thereby automatically suppressing heat generation of water.

And when the water is injected into the water inlet (1) when the appropriate amount of water is injected into the container (7), the flow sensor 51 detects the flow control unit 52 to operate the solenoid valve 53, the water is no longer Do not enter.

The present invention can be widely used in applications such as steam cleaner, steam iron, steam mugwort steamer, portable instant coffee pot, rice cooker.
