It is a thing. The blower 18 and the heat exchanger 19 are fixed to the support panel 17a and are covered with a decorative cover 17b. The heat exchanger 19 is connected to a heat source device 20 installed outdoors by a hot water pipe 21. An air inlet 22 is provided in the upper part of the decorative cover 17b, and a hot air outlet 23 is opened in the lower end or the lower surface of the front of the decorative cover 17b.

  Although not shown, the motor of the blower 18 is housed at the right end, and the crossflow fan and the heat exchanger 19 are housed on the left side. Therefore, as shown in FIG. 1, the air suction port 22 and the warm air outlet 23 are provided at positions that are biased to the left in accordance with the positions of the crossflow fan and the heat exchanger 19.

  In the heating device 11, when the outdoor ventilation device 14 is operated, moisture in the bathroom is discharged to the outside through the duct 16.

  Further, when high-temperature hot water is circulated from the heat source device 20 to the heat exchanger 19 and the blower 18 is operated, indoor air is sucked into the heating apparatus main body 12 from the air suction port 22. The sucked air is passed through the heat exchanger 19 by the blower 18, and is heated by exchanging heat with hot water circulating in the heat exchanger 19. As shown in FIG. 3, the heated hot air is discharged downward to heat the room.

  As shown in FIG. 1, the hot air outlet 23 has a louver blade 23 a for rotating up and down to adjust the hot air discharge direction up and down, and a left and right rotation of the hot air discharge direction to the left and right. A wind direction plate 23b is provided for adjustment. Therefore, the direction of the warm air blown from the warm air outlet 23 can be arbitrarily adjusted by adjusting the direction of the louver blade 23a and the wind direction plate 23b. Note that power such as a motor for rotating the louver blade 23a and the wind direction plate 23b may be provided so that the angle of the louver blade 23a and the wind direction plate 23b can be adjusted by a remote controller or the like.

  Next, the mist spraying unit 13 will be described. The mist spraying unit 13 includes a mist nozzle 25 that sprays hot water or water in a mist state, and a cover 26 that covers the mist nozzle 25. As shown in FIGS. 4A and 4B, the mist nozzle 25 is provided in the nozzle head 27, the connection port 29, the joint pipe 30 connecting the nozzle head 27 and the connection port 29, and the outer periphery of the connection port 29. The flange 31 is formed. A mechanism for spraying hot water or water in a mist form is provided in the nozzle head 27, and a connection port 29 is a member for connecting a hot water supply pipe 28 led from the heat source device 20, and a joint pipe 30 and the flange 31 serve to attach the nozzle head 27 to the heating device body 12 at a predetermined angle.

  FIG. 5A shows a lower horizontal piece 33 located on the lower surface portion of the support panel 17a. A groove-shaped notch 34 is provided at the front edge of the lower horizontal piece 33, on both sides thereof. A mounting hole 36 through which a screw passes is provided. Thus, the mist nozzle 25 is installed so that the joint pipe 30 is housed in the notch 34 and the flange 31 is placed on the upper surface of the lower horizontal piece 33, and the screw passing through the mounting hole 36 from the lower surface of the lower horizontal piece 33. 35 is screwed to the flange 31 to fix the mist nozzle 25 to the lower horizontal piece 33. One end of the hot water supply pipe 28 is connected to the connection port 29, the hot water supply pipe 28 is led to the outside through the duct 16, and the other end of the hot water supply pipe 28 is connected to the heat source device 20. As a result, the mist nozzle 25 is disposed below the hot air outlet 23 so as to protrude from the lower surface of the heating apparatus body 12 as shown in FIGS. 4 (a), 4 (b) and 5 (b). Further, since the heating device 11 is installed at a high place on the wall surface such as a bathroom, the nozzle head 27 is arranged to face obliquely downward.

  Since the mist nozzle 25 is fitted into the notch 34 of the lower horizontal piece 33 and can be easily attached, if the long part 37 without the cover 26 is prepared, the heater 11 having a mist generating function. It is also possible to share a heater that does not have a mist generating function. Moreover, since the mist nozzle 25 can be easily attached even after constructing the heater, the mist generation function can be easily retrofitted to a heating apparatus that does not have the mist generation function.

  FIG. 6 is a front view of the cover 26 covering the mist nozzle 25. The cover 26 is provided on the lower surface of the long portion 37 having a length over the entire width of the heating apparatus main body 12, and the cover 26 has a circular spray port 32 for spraying mist. The long portion 37 is detachably attached to the lower surface of the heating apparatus main body 12 by locking portions 39 provided at both ends.

  In a state where the cover 26 is attached to the lower surface of the heating apparatus main body 12, the tip of the nozzle head 27 is located in the vicinity of the spray port 32 and inside the cover 26 as shown in FIG. 3. Therefore, when high-temperature hot water is supplied from the heat source device 20 via the hot-water supply pipe 28, high-temperature hot water (for example, 60 ° C.) is discharged from the nozzle head 27 in the form of a mist, passes through the spray port 32, and enters the room. Sprayed and efficiently heated in the bathroom. Alternatively, the inside of the bathroom can be used as a mist sauna. In some cases, water can be sprayed and used as a shower.

  Further, in the heating device 11, as shown in FIG. 3, the discharge direction of the mist discharged from the nozzle head 27 (the center of the spread of the discharged mist) B is the warm air blown from the hot air outlet 23. The nozzle head 27 is installed so as to intersect the discharge direction (the center of the spread of the hot air blown out) A. Therefore, when the mist is sprayed during the heating operation, the mist discharged from the nozzle head 27 is swept downward by the warm air blown from the warm air outlet 23, and the mist is immediately sucked from the air suction port 22. Will be lost. Alternatively, the warm air blown from the warm air outlet 23 becomes an air curtain, and the mist is prevented from scattering toward the air inlet 22 side. Therefore, the mist is not sucked into the air suction port 22 and the efficiency of the mist is improved. Moreover, according to such a structure, the spraying direction of the mist discharged from the nozzle head 27 can be adjusted by changing the blowing direction of the warm air.

  As shown in FIG. 1, the cover 26 is provided between a location at a distance D2 from the left end of the heating device body 12 and a location at a distance D2 from the right end, and is disposed at the center of the heating device body 12. Yes. This is a design balance as a whole. On the other hand, the mist nozzle 25 is disposed at a distance D1 from the left end and the right end of the hot air outlet 23. That is, when the heating device 11 is viewed from the front, the mist nozzle 25 is disposed almost directly below the center of the hot air outlet 23 in the left-right direction. As a result, the mist is sprayed at the center of the warm air blown from the warm air outlet 23, and the mist is sprayed evenly by the warm air.

  In addition, while spraying mist or immediately after stopping spraying of mist, warm water or water drops that have condensed or adhered to the nozzle head 27 fall downward. When high-temperature mist is discharged from the nozzle head 27, the temperature is about 60 ° C., so that it may feel hot when it falls on the human body. Moreover, even in the case of water drops, it gives discomfort. Therefore, in the heating device 11 of this embodiment, as shown in FIG. 7, the nozzle head 27 is slightly retracted to the inner surface side of the cover 26, and drops that fall from the nozzle head 27 are received by the cover 26. Since the nozzle head 27 is retracted inside the cover 26, it is possible to prevent a hand from touching the nozzle head 27 and feeling a sense of heat.

  However, if the droplet attached to the tip of the nozzle head 27 flows toward the tip of the nozzle head 27 and accumulates at the tip of the nozzle head 27 and falls downward, it may drop downward through the spray port 32. Therefore, the lower surface 38 of the tip portion of the nozzle head 27 is inclined obliquely downward at an inclination angle β toward the rear. Accordingly, the hot droplets accumulated at the tip of the nozzle head 27 flow backward along the inclination of the lower surface 38 as indicated by the arrow. Then, the drops that fall downward at the rear end of the lower surface 38 are reliably received by the cover 26.

  Further, the inner surface of the bottom piece 40 of the cover 26 is inclined obliquely downward with an inclination angle α toward the rear. Therefore, the drops that have fallen on the cover 26 are discharged toward the rear as indicated by the arrows in FIG. 7 without accumulating on the bottom piece 40. Drops discharged backward flow down along the wall surface of a bathroom or the like and are drained.

  8 and 9 are diagrams for explaining a modification of the present invention. In this modification, as shown in FIG. 8A, the attachment hole 36 provided in the lower horizontal piece 33 is a long hole that is long in the front-rear direction. Therefore, when the mist nozzle 25 is attached to the lower horizontal piece 33 (for example, at the construction site), the mist nozzle 25 can be rotated by rotating the mist nozzle 25 as shown by an arrow in FIG. 8B. . Corresponding to this, as shown in FIG. 9, the spray port 32 of the cover 26 is also a long hole in the lateral direction. Therefore, according to this modification, it becomes possible to adjust the spraying direction of mist at the time of installation.

  Although not shown, a plurality of mist nozzles 25 or nozzle heads 27 such as two or three may be provided.
