Abstract

PURPOSE:To prevent the adhesion and accumulation of impurities on the inner wall of an evaporation cylinder, and thereby extend the lifetime of a humidification device, by installing a floating member inside the evaporation cylinder in such a manner that the float member may move freely. CONSTITUTION:When electricity is supplied to a heating element 3, an evaporation cylinder is heated. As a result, with a rise in temperature, the water in the evaporation cylinder is boiled up, thereby generating steam. The steam is discharged from a blowoff port 7 outside the equipment, thereby humidifying the air. At the same time, a float member 4 hops by a rising power or a bursting power of air foams generated in the hot water. The outside peripheral parts of the floating member constantly scrub out the inner wall of the evaporation cylinder 2 and scale off the impurities of the water adhered to the inner wall. Furthermore, when the floating member is formed by fluorine resin or other materials, then coated with fluorine resin on the surface, its excellent water or oil repellency, can prevent the adhesion of impurities on the floating member itself and maintain the cleaning capacity of the evaporation cylinder for long time.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electrically heated humidifier for preventing a room from drying out.

Conventional technology A conventional humidifying device is shown in FIG.

A tank 1 having a water supply port 1a and a drain port 1b, a cylindrical evaporator 2 whose one end is connected to the water supply port 1a and the other end to the water receiver 6 via a vibro, and an outer periphery of the evaporator 2. It consisted of a heater 3 that was closely fixed. Note that 7 is a steam outlet (for example, Japanese Utility Model Publication No. 58-29).0 Because of the above configuration, when water is supplied from the water receiver 6, the evaporator tube 2
When water enters the tank 1 through the , and electricity is applied to the heating element 3, the evaporator cylinder 2 is heated, the water in the evaporator cylinder 2 rises in temperature, boils, generates steam, and is discharged from the blow-off lower to the outside of the vessel. be done. Also, when the water level falls below the level of the evaporator tube 2, the amount of steam generated is extremely low, so water is supplied here and used for connection, and when the season is over, the remaining water is discharged and stored through the drain port 1b. Ta.

Problems to be Solved by the Invention Conventional humidifying devices have the above-mentioned structure (9), but impurities contained in water remain on the inner wall of the evaporator cylinder, and the concentration of impurities in the remaining water increases with repeated use. Since the amount of impurities adhering to the inner wall also increases at an accelerated pace, the life of the device was short.

Means for Solving the Problems In order to solve the above problems of the conventional example, the humidifying device of the present invention includes a tank having a water supply port and a drain port, one end of which is connected to the water supply port, and the other end of which is connected to a water receiver. The evaporator was constructed of a cylindrical evaporator, a heating element closely fixed to the outer periphery of the evaporator, and a float member movably disposed inside the evaporator.

How it works With this configuration, when water is supplied from the water receiver and electricity is applied to the heating element, the evaporator is heated and the temperature of the water inside the evaporator increases.

In addition to boiling water and generating steam, the float members dance and constantly rub against the inner wall of the evaporator cylinder due to the rising force and bursting force of the bubbles in the vortex, scraping off impurities in the water that adhere to the inner wall, so it is repeatedly heated. Even if the concentration of impurities in the remaining water increases due to use, the adhesion of impurities to the inner wall of the evaporator cylinder will not be accelerated, and a predetermined humidifying capacity can be maintained for a long time.

EXAMPLE An example of the humidifying device of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional structural view of one embodiment of the present invention, and FIG. 2 is a perspective view of a float member in the same embodiment. In FIG. 1, reference numeral 1 denotes a hollow tank formed into a substantially J-shape by blow molding or the like, and has a drain port 1b at the top and a water supply port 1a at the bottom. 2 is a cylindrical evaporator tube made of steel pipe or the like, and on its outer periphery is a heating element 3 insulated with an insulating sheet made of synthetic mica or the like.
The evaporator tube 2 has one end connected to the water supply port 1a of the tank 1, and the other end connected to the water receptacle 6 and a connecting vibro tube made of silicone rubber or the like. connected by.

Reference numeral 4 denotes a disk-shaped float member whose outer diameter is slightly smaller than the inner diameter of the evaporator tube 2, and is inserted into the evaporator tube 2 without being fixed.

The operation of the embodiment of the present invention having the above configuration is that when the blow-out lower is first opened and water is supplied from the water receiver 6, the water is supplied into the tank 1 via the evaporator 2, and the water level in the tank 1 and the evaporator 2 is the same. keep it. When the heating element 3 is energized, the evaporator 2 is heated and the temperature of the water inside the evaporator 2 increases.

Boiling water generates steam, which is discharged from the blowout lower to the outside of the vessel to humidify the air.The floating member 4 dances due to the rising force and bursting force of the bubbles generated in the vortex, and its outer periphery forms the inner wall of the evaporator tube 2. ◇ The scraped impurities remain in the remaining water, and can be drained together with the remaining water from the drain port 1b by tilting the vessel.

Furthermore, if the float member is made into a disk shape with a hollow part 4a in the center and a groover 4b connected to the saw blade-shaped outer peripheral part 4C as shown in Fig. 2, the float member 4 will be rotated by the rising force of air bubbles generated in the hot water. The uneven surface on the outer periphery can rub the inner wall of the evaporator cylinder 2 to remove impurities more cleanly.

Furthermore, if the above-mentioned float member is molded with fluorine resin, or is molded with other materials and then coated with fluorine resin, its excellent oil repellency will prevent impurities from adhering to the float member itself. The cleaning action of the evaporator cylinder can be maintained for a long time.

Effects of the Invention (1) The humidifying device of the present invention prevents impurities from accumulating on the inner wall of the evaporating cylinder by movably disposing the float member inside the evaporating cylinder, thereby dramatically extending the life of the humidifying device. The practical effects are great.

(2) By providing the float member with a propeller part and an outer circumferential surface with unevenness, the float part has an effect of scraping off impurity deposits by 4° to 3° by vertical movement and rotational movement.
