Abstract

PURPOSE:To quickly generate steam after heating begins by a method wherein time sheet surface of a plane heating sheet is held vertically to the bottom of a casing, and part of the sheet except the sheet upper edge is immersed in liquid. CONSTITUTION:Water is poured in a lower casing 10B from an opening 11 so that the lower part of a plane heating sheet 20 except the upper edge part 21 is immersed in the water. When water-soluble perfume is added, users can enjoy fragrance in addition to humidification. When a switch 12 with temperature control function is turned on to make the sheet 20 generate heat, steam is generated from the part immersed in water, reheated by the upper edge part 21 and discharged from the opening 11. The plane heating sheet 20 is of a water-proof heating sheet that is paper blend containing carbon fiber and plant pulp and impregnated with ABS resin, and silver paste electrodes 22A and 22B are coated on both opposite hems. Thereby, a thin type humidifier which is capable of quickly discharging steam throughout a room after heating begins can be obtained.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thin humidifier.

0002

[Prior Art] Humidifiers for preventing indoor air from drying out during periods when the air is dry, such as winter, have conventionally been used.
Various proposals have been made. The humidifying device includes a pipe-type humidifying device that passes water through a pipe or the like and releases steam by heating the pipe, and an evaporating dish that sends water to an evaporating dish and releases steam by heating the evaporating dish. There are type humidifiers and ultrasonic humidifiers that atomize and release water using a vibrator that emits ultrasonic waves.

0003

[Problems to be Solved by the Invention] However, in the pipe-type humidifier, trace components and impurities contained in the water remain in the device due to water evaporation, and this adheres to the inner wall of the device, resulting in deterioration of function. Furthermore, there is a recent trend of making pipes thinner in order to improve the vaporization rate, and there is a problem that there is a high risk of pipes becoming clogged due to the trace components and impurities, resulting in accidents. There is. Furthermore, in the case of a pipe-type humidifier, since the opening through which steam is ejected is narrow, it is difficult to humidify the entire room quickly and uniformly.

[0004] Furthermore, in the evaporating dish type humidifier, since the evaporating dish is heated after sending water to the evaporating dish, the immediate effect and the amount of steam blown out are poor, and the situation when there is no water in the evaporating dish is poor. There is also a problem in that there is a high risk of physical accidents due to the heating that takes place.

Furthermore, in the ultrasonic humidifier, trace components such as calcium and magnesium contained in the water,
Dirt and impurities in the atomization chamber are also atomized and released, so there is a problem that they may adhere to furniture, electrical appliances, etc., impairing quality, or have a negative impact on the human body. Because of the atomization, bacteria breed in the water storage tank, which poses a sanitary problem. Furthermore, since the water is discharged while still being cold, there is a problem that heating efficiency decreases in winter and the like.

[0006] Recently, as the design of electrical products has improved, there has been a demand for the development of thin humidifiers that can be hung on walls, etc., and humidifiers that consume less power.

[0007] Accordingly, an object of the present invention is to provide a thin humidifying device that can quickly release steam throughout the room after heating has started, and is less susceptible to the effects of trace components contained in water.

Another object of the present invention is to provide a thin humidifier that can safely and sanitarily humidify a room without impairing heating efficiency even during winter.

Another object of the present invention is to provide a thin heating type humidifying device that consumes less power and has excellent humidifying efficiency.
