  Hereinafter, the present invention will be described based on the embodiment shown in FIGS.

  For example, as shown in FIGS. 1 and 2, the superheated steam heater 10 according to this embodiment includes a water supply unit 11 that supplies water W and superheated steam S using water W supplied from the water supply unit 11. A superheated steam generator 12, a blower 13 for sending out the superheated steam S generated in the superheated steam generator 12, and a housing 14 for housing these devices, The superheated steam generator 12 communicates with the duct 15 so that the superheated steam S generated in the superheated steam generator 12 is blown from the blower opening 14 </ b> A to the outside, that is, the room by the blower 13.

  As shown in FIGS. 1A to 1C, the housing 14 has a vertically long, substantially rectangular parallelepiped shape, and a blower opening 14A is formed on the front surface, and handles 14B are formed on both left and right side surfaces. Further, as shown in FIG. 1A, an opening for inserting and removing a water tank, which will be described later, is formed on the upper surface of the housing 14, and this opening can be opened and closed by a hinged single-open lid 14C. ing. Further, on the upper surface of the housing 14, operation switches necessary for the heating machine such as a power switch 14D and a temperature setting switch 14E, a temperature display unit, and the like are attached.

  Thus, the water supply unit 11 only needs to have a function of supplying the water W to the superheated steam generation unit 12, and is not limited to a specific structure. As shown in FIGS. 2 and 3, for example, the water supply unit 11 in this embodiment includes a cartridge-type water tank 111, a holder 112 that holds the water tank 111, and a bottom of the water tank 111 that is held by the holder 112. A fixed water tank 113 disposed on the side, and is configured to directly supply water W from the fixed water tank 113 to the superheated steam generator 11. A water stopper 111A containing a valve (not shown) is screwed into the water supply port of the water tank 111. Further, the fixed water tank 113 is formed with a fitting portion 113A into which the plug 111A of the water tank 111 is fitted. When the water tank 111 is mounted on the holder 112, the plug 111A of the water tank 111 is fixed to the fixed water tank. The valve of the stopper 111 </ b> A is opened by a pin (not shown) fitted to the fitting portion 113 </ b> A of 113, and water W is supplied from the water tank 111 to the fixed water tank 113. When the valve of the plug 111 </ b> A is blocked by the water in the fixed water tank 113, air does not enter the water tank 111, so the supply of water from the water tank 111 to the fixed water tank 113 is stopped. The plug 111A of the water tank 111 and the fitting portion 113A of the fixed water tank 112 are conventionally known.

  In the present embodiment, the water W is supplied from the water tank 111 to the fixed water tank 113. However, for example, tap water may be supplied directly to the fixed water tank 113.

  The superheated steam generation unit 12 only needs to have a function of receiving the water W from the water supply unit 11 and generating the superheated steam S, and is not limited to a specific structure. As shown in FIGS. 2 and 3, the superheated steam generation unit 12 in the present embodiment includes an annular container 121 that receives water W from the fixed water tank 113, a heater 122 disposed inside the annular container 121, The water W in the annular container 121 is heated by the inner heater 122 to generate superheated steam S. As shown in FIG. 4, the annular container 121 includes an outer cylinder 121A, an inner cylinder 121B having a smaller diameter than the outer cylinder 121A, an annular lower surface that connects the lower end of the outer cylinder 121A and the lower end of the inner cylinder 121B (see FIG. A fixed water tank in a space 121D (see FIG. 4) between the outer cylinder 121A and the inner cylinder 121B, and an annular upper surface 121C connecting the upper end of the outer cylinder 121A and the upper end of the inner cylinder 121B. It is configured to generate superheated steam from water W received from 113. As shown in FIG. 4, a plurality of holes 121E are formed at equal intervals in the circumferential direction on the annular upper surface 121C of the annular container 121, and superheated steam generated in a space 121D between the outer cylinder 121A and the inner cylinder 121B. As shown in FIG. 2, S is discharged from a plurality of holes 121E in the upper surface 121C.

And the annular container 121 and the fixed water tank 113 are mutually connected via the 1st, 2nd piping 16A, 16B arrange | positioned up and down, as shown in FIG. 2, FIG. One end of the first pipe 16 </ b> A is connected to the lower surface of the fixed water tank 113, and the other end is connected to the lower part of the outer cylinder 121 </ b> A of the annular container 121. One end of the second pipe 16B is connected to the side surface of the fixed water tank 113, and the other end is connected to the vicinity of the upper portion of the outer cylinder 121A. By arranging the first and second pipes 16A and 16B up and down, the water W in the water tank 111 is exhausted, the water in the fixed water tank 113 is reduced, and the water level is lower than the level of the second pipe 16B. Even so, since the space 121D of the annular container 121 and the space of the fixed water tank 113 communicate with each other through the second pipe 16, the superheated steam S in the annular container 121 is transferred from the second pipe 16B to the fixed water tank. It flows into 113, the inside of annular container 121 and the inside of fixed water tank 113 become equal pressure, and keeps the water level in annular container 121 constant. When the water in the fixed water tank 113 runs out due to heating, the heater 122 is automatically turned off.

  The heater 122 is not particularly limited as long as it has a function of heating the annular container 121 so as to generate the superheated steam S from the water W in the annular container 121. As shown in FIGS. 2 to 4, the heater 122 in this embodiment is formed so as to cover the entire surface of the inner cylinder 121 </ b> B by spirally winding upward from the lower end of the inner cylinder 121 </ b> B of the annular container 121. The upper end protrudes from the upper end of the annular container 121. In this way, by heating the entire annular container 121 from the inside with the heater 122, the superheated steam S can be reliably generated in the annular container 121. Further, the superheated steam S discharged from the plurality of holes 121E of the annular container 121 is heated by the projecting portion 122A of the heater 122 projecting from the upper end of the annular container 121 to further raise the temperature of the superheated steam S. By raising the temperature to around 200 ° C., the heat capacity of the superheated steam S is increased and the heating efficiency is increased. In the present embodiment, for example, a sheathed heater is used as the heater 122. The heater 122 can be set to an appropriate temperature by a temperature setting switch 14F provided on the upper surface of the housing 14.

  In the present embodiment, a sheathed heater is used as the heater 122, but it is needless to say that the sheathed heater is not limited.

  Further, as shown in FIGS. 2 and 3, the blower 13 is formed by a turbo fan, for example, and is disposed below the superheated steam generator 12. The rotating shaft 12A of the blower 13 is connected to one end of the rotating shaft of the electric motor 17 disposed below the fixed water tank 113, and is rotated by the electric motor 17 to be a space in which the heater 122 inside the annular container 121 is disposed. The air is blown to. In addition, the other end of the rotating shaft of the electric motor 17 is connected to a fan (for example, a propeller fan) 18 disposed below the fixed water tank 113, and an air intake ( External air is sucked from (not shown) and the electric motor 17 is cooled.

  The air blown into the annular container 122 by the blower 13 is heated by the heater 122 there. This heated air is mixed with the superheated steam S discharged from the plurality of holes 121E on the upper surface 121D of the annular container 122. The mixed superheated steam S and heated air are guided to the air blowing port 14A of the housing 14 through the duct 15 of the annular container 121, discharged from the air blowing port 14A to the outside, and used for heating.

  The superheated steam S generated in the superheated steam generator 12 has a large heat capacity, is dry, and has excellent heat transfer properties. Therefore, even if it is discharged into the room, it diffuses into the whole room together with the heated air. Can be efficiently heated, and there is no condensation on the wall surface of the room that humidifies the room. Therefore, there is no need to provide a humidifier other than the superheated steam heater 10, and indoor drying can be reliably prevented. Furthermore, since the superheated steam S radiates far infrared rays, the body-friendly heating can be performed.

  Next, the operation will be described. The superheated steam heater 10 is disposed at a desired location. Then, the cartridge-type water tank 111 of the water supply unit 11 is filled with water W, the lid 14D of the casing 14 is opened, the water tank 111 is attached to the holder 112 in the casing 14, and the lid 14C is closed. The water W in the water tank 111 flows into the fixed water tank 113 from the stopper 111A, the water W is filled in the fixed water tank 113, and from the fixed water tank 113 into the annular container 121 of the superheated steam generator 12. Water W flows in and the supply of water from the water tank 111 to the fixed water tank 113 is stopped.

  Next, when the power switch 14D is operated to turn on the power, the electric motor 17 is driven and the heater 122 is activated. As the electric motor 17 is driven, the blower 17 rotates to blow the air in the housing 14 to the heater 122. At the same time, air is sucked into the housing 14 from the outside by the propeller fan 18 to cool the electric motor 17 and replenish air to the blower 13 side.

  When the heater 122 of the superheated steam generator 12 is activated, the water W in the annular container 121 is heated and steam is generated. The steam is further heated by the heater 122 in the annular container 121 to become superheated steam S and is discharged upward from the plurality of holes 121E of the annular container 121. At this time, the air blown by the blower 13 is heated by the heater 122, and the heated air and the superheated steam S are mixed while passing through the duct 15 and supplied to the room from the blower opening 14 </ b> A of the housing 14.

Even if the water W in the water tank 111 is exhausted during heating and the water level in the fixed water tank 113 is lower than the second pipe 16B , the annular container 121 and the fixed water tank 113 are connected to the second pipe 16B . Therefore, the inside of the annular container 121 and the inside of the fixed water tank 113 become equal in pressure, and the water level in the annular container 121 is kept constant. When the water W in the fixed water tank 113 runs out, the power supply is automatically cut off, and the heater 122 prevents the annular container 121 from being blown.

As described above, according to the present embodiment, the superheated steam heater 10 generates the superheated steam S using the water supply unit 11 that supplies the water W and the water W that is supplied from the water supply unit 11. an overheated steam generator 12, a blower 13 for feeding superheated steam S generated in the superheated steam generator 12, a housing 14 for accommodating these devices 11, 12, 13, provided with a superheated steam generator 12 And an annular container 121 that receives water W from the water supply unit 11 and a heater 122 disposed inside the annular container 121, and the superheated steam S is discharged onto the annular upper surface 121 </ b> C of the annular container 121. a plurality of holes 121E are formed at equal intervals in the circumferential direction, heating the superheated steam S generated in the superheated steam generator 12 by the blower 13 and blown from the air blowing port 14A to the outside Since it is configured so that, reliably to generate superheated steam S in the annular chamber 121 by the heater 122 disposed inside the annular chamber 121 in the superheated steam generating unit 12, the superheated steam S from a plurality of holes 121E While being discharged, the superheated steam S and the heated air can be mixed and blown through the blower 13, and as a result, there is no generation of carbon dioxide due to combustion of oil or the like, and environmentally friendly heating can be performed. The room can be efficiently heated in a short time without drying the room with the superheated steam S. Moreover, since the superheated steam S radiates far infrared rays, the body-friendly heating can be performed. Moreover, according to this embodiment, since heating efficiency is good and fuel, such as oil, is not used, there is no environmental load, energy saving can be promoted, and an electricity bill can be saved.

  Further, according to the present embodiment, the heater 122 is spirally formed along the entire inner peripheral surface of the annular container 121, and the upper end of the heater 122 protrudes from the upper end of the annular container 121. The superheated steam S discharged from the plurality of holes 121E of the annular container 121 can be further heated by the protruding portion 122A of 122 to obtain the superheated steam S having a large heat capacity, and the heating efficiency can be further increased.

  In addition, this invention is not restrict | limited to the said embodiment at all, and can change the design of each component suitably as needed.

  INDUSTRIAL APPLICABILITY The present invention can be suitably used not only as a home heater but also as an industrial heater such as a greenhouse for greenhouse cultivation.
