  In view of the above, the present invention provides a compact bathroom heater with a hot water hot water function capable of preventing hot water discharged from a hot water nozzle from being blown by hot air blown from a blowout port. That is the issue.

  In order to solve the above-described problems, the present invention provides a bathroom heater that is installed on a ceiling of a bathroom, above a bathtub, and a cover that covers a lower surface of the main body of the heater has an inlet and an outlet. An air passage formed between the air inlet and the air outlet, a circulation fan for circulating the air in the bathroom through the air passage, heating means for heating the air flowing through the air passage, and a bathtub. In addition to a hot water nozzle that drops hot water toward the surface, it is equipped with a closing plate part that closes a part of the suction port, and a hot water nozzle that is placed facing the through hole established in the closing plate part is arranged It is characterized by being.

  According to the present invention, since the through hole that faces the hammered hot water nozzle is formed in the closing plate portion that closes a part of the suction port, it is located outward from the side edge of the suction port opposite to the outlet port. There is no need to form an overhanging portion on the cover, and the bathroom heater becomes compact. And since the hammered hot water nozzle will be located in the suction port away from the blower outlet, it can prevent that the hot water discharged from the hammered hot water nozzle is swung by the warm air blown from the blower outlet and shakes. Moreover, it is possible to prevent the air sucked into the suction port from flowing into the placement portion of the hot water nozzle by the blocking plate portion, and the hot water falls straightly from the hot water nozzle.

  Moreover, in this invention, it is desirable for the installation direction of the bathtub with respect to the washroom of a bathroom to be one side in the horizontal direction, and a suction inlet to be located in one side of the horizontal direction of a blower outlet. Here, the installation position of the bathroom heater is ideally right above the bathtub, but in reality, the bathroom heater will be installed at a position shifted from the position directly above the bathtub to the washroom side (the other in the horizontal direction). Sometimes. And in the present invention, since the hot water nozzle is located in the suction port, when the suction port is located on the other side in the horizontal direction of the outlet, when the installation position of the bathroom heater is shifted to the other side in the lateral direction, There is a possibility that hot water from the hot water nozzle will fall into the washing area. On the other hand, if the suction port is located on one side of the outlet as described above, the suction port is located above the bathtub, even if the installation position of the bathroom heater is significantly shifted to the other side. Hot water from the hot water nozzle falls into the bathtub.

  Further, in this case, it is desirable that the through hole is formed in a horizontally long shape, and the hot water nozzle is displaceable in the lateral direction within the through hole. According to this, even if the installation position of the bathroom heater is shifted in the horizontal direction, the hot water from the hot water nozzle is displaced to a predetermined position in the bathtub by displacing the hot water nozzle in the direction opposite to the shifted direction. Can be dropped. Furthermore, the drop position of the hot water can be changed according to the user's preference.

As shown in FIGS. 2 and 3, the cover 3 has a suction port 4 with a fixed louver 4 a that extends over substantially the entire area of one half in the horizontal direction, and a variable louver 5 a that is located on the other side in the horizontal direction of the suction port 4. A blowout port 5 is formed.

  In the heater body 2, a ventilation path 6 that connects the suction port 4 and the outlet 5, a circulation fan 7 that circulates the air in the bathroom BR through the ventilation path 6, and the air that flows through the ventilation path 6 are heated. A radiator 8 serving as a heating means is provided. The radiator 8 is supplied with a heat medium (water, antifreeze liquid, etc.) heated by a heating section of a hot water supply / heating heat source machine (not shown). Then, the air in the bathroom BR sucked into the ventilation path 6 from the suction port 4 by the operation of the circulation fan 7 is heated by the radiator 8 and is blown into the bathroom BR from the blowout port 5 as warm air.

  A filter 9 is mounted on the upper side of the suction port 4. An inlet / outlet port 10 in which a handle 9a at the side end of the filter 9 is accommodated is formed in a portion between the suction port 4 and the outlet port 5 of the cover 3 so that the filter 9 can be inserted and removed through the inlet / outlet port 10. .

  Further, the cover 3 is provided with a pair of mist nozzles 11 located at a portion adjacent to the other side in the horizontal direction of the outlet 5. Each mist nozzle 11 sprays hot water heated by a liquid heat exchanger (not shown) that supplies a heat medium from the heating unit of the hot water supply / heating heat source machine. The sprayed hot water mist is supplied into the bathroom BR on hot air blown from the outlet 5.

  Moreover, the bathroom heater 1 is provided with the hot water nozzle 12 which drops the hot water from the hot water supply part of the hot water supply heating heat source machine toward the bathtub BT. Hereinafter, this point will be described.

  In the present embodiment, the central portion in the front-rear direction of the suction port 4 is closed from the lateral side edge of the suction port 4 (the side edge opposite to the outlet port 5) to the lateral center portion of the suction port 4. A blocking plate portion 4b is provided. Then, a horizontally long through hole 4c is formed in the closing plate portion 4b, and the hot water nozzle 12 is arranged so as to face the through hole 4c. The portion of the filter 9 located on the closing plate portion 4b is cut out so that the filter 9 can be inserted and removed without interfering with the hot water nozzle 12.

  Referring to FIG. 4, an elbow pipe 13 bent in the front-rear direction is connected to the upper end of the hot water nozzle 12 using a clip 13a. An elbow pipe 13 is rotatably connected to an outflow hole 14a having a hole axis in the front-rear direction of a control valve 14 that controls the supply of hot water to the hot water nozzle 12 using a clip 14b. As a result, the hot water nozzle 12 can be swung laterally about the hole axis in the front-rear direction of the outflow hole 14a. As a result, the hot water nozzle 12 struck in the horizontally long through-hole 4c can be displaced in the lateral direction.

  In addition, referring to FIG. 3, the portion where the through hole 4 c of the closing plate portion 4 b is formed is formed in a circular arc shape concentric with the center of swinging of the tapping hot water nozzle 12. A blindfold plate 15 having an arcuate cross section that contacts the upper surface of the blocking plate portion 4b is connected to the hot water nozzle 12 to prevent the inside from being seen through the through hole 4c. In FIG. 4, the blindfold plate 15 is omitted.

  By the way, it is also conceivable to arrange the hot water nozzle 12 side by side with the mist nozzle 9 in the vicinity of the outlet 5. However, in this case, the hot water discharged from the hot water nozzle 12 may be swung by the hot air blown from the outlet 5, and the hot water may not be applied to the bather. Further, the cover 3 is formed with a projecting portion that projects outward from one side edge of the suction port 4 in the lateral direction (the side edge opposite to the blowout port 5), and faces the through hole formed in this projecting portion. It is also conceivable to dispose the hot water nozzle 12. However, this increases the size of the bathroom heater due to the formation of the overhang portion on the cover 3.

  On the other hand, in this embodiment, since the through hole 4c that faces the hot water nozzle 12 is formed in the closing plate portion 4b that closes a part of the suction port 4, one side of the suction port 4 in the lateral direction. It is not necessary to form an overhanging portion that protrudes outward from the edge on the cover, and the bathroom heater 1 becomes compact. And since the hot water nozzle 12 is located in the suction inlet 4, it is possible to prevent the hot water discharged from the hot water nozzle 12 from being swung by the hot air blown from the outlet 5 and swaying. Moreover, it can prevent by the obstruction | occlusion board part 4b that the air inhaled by the suction inlet 4 flows into the arrangement | positioning part of the hot water nozzle 12, and warm water falls straight from the hot water nozzle 12.
