Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an evaporator used in electric stoves, kerosene stoves, air conditioners, etc. when humidifying a room.

[Conventional technology]

Conventionally, when heating a room with an electric stove or the like, it was possible to raise the temperature, but at the same time, the humidity tended to decrease and the air became dry. but,
Since too dry air is not good for health, some electric heaters were equipped with evaporation devices for humidification to prevent the indoor humidity from dropping. In this structure, as shown in FIGS. 4 and 5, a water tank 15 is provided in the upper part of the electric stove 14, one end of a U-shaped tube 13 is connected to the lower end of this water tank 15, and the other end is connected to the bottom end of the water tank 15. A tube 1 whose end is connected to an evaporator 16 opened on the top surface of the electric stove 14 and located below the evaporator 16
3 is replaced with a copper pipe 11, and the circumferential surface of the copper pipe 11 is heated with a heating means 12 such as a bobbin heater coated with insulation by winding a nichrome wire into a coil, thereby removing the water in the copper pipe 11. It was designed to be evaporated and discharged from the evaporation port 16.

[Problem that the invention attempts to solve]

However, this structure has a problem in that water suddenly flows out from the evaporator B when the electric stove 14 falls over.

Therefore, the object of this invention is to provide an evaporation device that can prevent water from flowing out even when an electric stove or the like falls over.

[Means for solving problems]

The evaporator of this invention has an impermeable layer formed on the circumferential surface of a water-absorbing ceramic body with an upper part as an evaporating part and a lower part as a suction part, and a heating means provided outside the water-impermeable layer.

[Effect]

According to the structure of this invention, water is sucked up and absorbed by the water-absorbing ceramic body, so even if the user falls over, the water will not suddenly flow out.

〔Example〕

An embodiment of this invention will be explained based on FIGS. 1 to 3. This evaporation device includes a water tank 6 provided in the upper part of an electric stove 5.
The water in the water tank 6 is evaporated by the evaporator A and discharged from the evaporator port 7 provided on the top surface.
A water-absorbing ceramic body 1 having an evaporating part 1a at the upper part and a suction part 1b at the lower part is provided in the tube 4 which connects the water-absorbing ceramic body 1 to the evaporating port 7.
An impermeable layer 2 is formed on the circumferential body surface of glaze or synthetic resin, and a heating means 3 such as a bobbin heater is provided on the outside of the impermeable layer 2.

The water-absorbing ceramic body 1 is, for example, made by mixing flammable powder into a raw material mainly composed of silica, molding and firing, and can absorb water of 50% or more of its own weight. The shape is formed into a round bar shape to match the tube 4.

The impermeable layer 2 is made of glaze or synthetic resin,
The circumferential surface of the water-absorbing ceramic body 1 is covered to prevent absorbed water from flowing out from the surface.

The heating means 3 is composed of a bobbin heater or the like made of a nichrome wire wound into a coil and coated with insulation, and heats the water absorbed in the water-absorbing ceramic body 1 and converts it into steam.

The operation of this embodiment will be explained. Fill the water tank 6 with water from the water supply port 8. Water reaches the water-absorbing ceramic body 1 through the tube 4 and is sucked upward from the suction 1b at the bottom. At the same time as the main heater 9 of the electric stove 5 is turned on, the evaporator A is turned on. At the same time as the indoor air is warmed by the main heater 9, the evaporator A is also warmed by the heating means 3, and steam is evaporated from the evaporation part 1a at the upper part of the water-absorbing ceramic body 1 and discharged from the evaporation port 7. Increase indoor humidity.

According to the configuration of this embodiment, since the water-absorbing ceramic body 1 is provided in a part of the tube 4 that connects the water tank 6 and the evaporation port 7, even if the kerosene stove 5 falls over, the water-absorbing ceramic body 1 serves as a water stop valve, and water does not suddenly flow out from the evaporation port 7. Further, since the water-impermeable layer 2 is formed on the circumferential surface of the water-absorbing ceramic body 1, the water absorbed in the water-absorbing ceramic body 1 does not ooze out from the surface and does not adversely affect the heating means 3 and the like. Moreover, when water is absorbed into the water-absorbing ceramic body 1, the amount of water is smaller than before.
Moreover, since it is easily heated through the water-absorbing ceramic body 1, steam can be generated with a small amount of heat, and the efficiency of evaporation is improved.

In addition, in the said Example, although the evaporator A was provided in the electric stove 5, it may be provided in a kerosene stove, an air conditioner, etc.

Further, in the above embodiment, the water-absorbing ceramic body 1 is shaped like a round bar, but it may have any shape, and may be shaped like a plate. In this case, the heating means 3 may be a planar heater.

Moreover, as the heating means 3, a thermal conductor that guides the heat of the main heater 9 of the electric stove 5 may be connected to the evaporator A instead of the bobbin heater.

[Effect of idea]

According to the evaporator of this invention, a water-absorbing ceramic body is provided with an evaporation section at the top and a suction section at the bottom, and an impermeable layer is formed on the circumferential surface of the body, so that the water-absorbing ceramic body absorbs water. , water will not suddenly flow out even if the device is tipped over.
Moreover, the water absorbed by the water-absorbing ceramic body does not ooze out from the surface and does not have any adverse effect on the heating means or the like. In addition, when water is absorbed into the water-absorbing ceramic body, the amount of water is small and is more easily heated through the water-absorbing ceramic body, so steam can be generated with a small amount of heat. This has the effect of increasing evaporation efficiency.
