Description

  The present invention relates to a ceiling-embedded bathroom heater with a mist function capable of ejecting hot and cold water into a bathroom in a mist form.

  The ceiling-embedded bathroom heater defines a ventilation path that connects the air inlet and the outlet that are installed in parallel to the cover that covers the opening on the lower surface of the airframe in the body installed so as to be embedded in the ceiling of the bathroom. A circulation fan and a heating means are arranged on the road, and the bathroom is heated by circulating the air heated by the heating means to the bathroom by the circulation fan.

  Conventionally, in such a ceiling-embedded bathroom heater, a spray port is provided in the cover, a spray head is arranged facing the spray port, and hot water is jetted from the spray head in the bathroom in a mist shape, thereby providing a mist sauna effect. Is known (see, for example, Patent Document 1).

In this case, the spray port is provided in the cover portion outside the suction port. Here, in order to enhance the sauna effect, a heating operation in which air heated by the heating means is circulated by a circulation fan at the same time as the mist operation in which hot water is jetted in a mist form may be performed. When the circulation fan is operated during the mist operation in this way, a part of the hot and cold water mist is sucked into the suction port near the jet port by the suction force of the circulation fan and aggregates as water droplets. Aggregated water droplets gradually grow and eventually drop on a person taking a bath, which may cause discomfort.
JP 2002-336327 A

  In view of the above, the present invention suppresses the suction of hot water mist into the suction port when the circulation fan is operated during mist operation, and prevents the growth and dripping of water droplets. The challenge is to provide a type bathroom heater.

  In order to solve the above problems, the present invention defines a ventilation path connecting a suction port and a blowout port arranged in parallel to a cover that covers the lower surface opening of the aircraft, in the aircraft installed so as to be embedded in the ceiling of a bathroom. This is a ceiling-embedded bathroom heater in which a circulation fan and heating means are arranged in the ventilation path, provided with a spray port on the cover, spraying hot water into the bathroom in a mist form facing this spray port In the arrangement of the head, the spray port is provided in a portion of the cover located on the opposite side of the suction port with the blowout port interposed therebetween.

  According to the present invention, even when the circulation fan is operated during the mist operation, the air flow blown into the bathroom from the blowout port functions as an air curtain that partitions the spray port and the suction port, and the hot water mist suction port. Suction into the water is effectively suppressed. Accordingly, it is possible to prevent a problem that the hot water mist sucked into the suction port aggregates and grows as water droplets and drops on a person taking a bath to give unpleasant feeling.

  In addition, it is desirable that the spray port is formed so as to be adjacent to the blowout port. According to this, a spray head will also be arrange | positioned adjacent to a blower outlet, and size reduction of a bathroom heater can be achieved. Furthermore, the hot water mist from the spray head can easily ride on the air flow blown from the outlet, and the hot water mist can be spread over a wide range.

  Referring to FIG. 1, reference numeral 1 denotes a ceiling embedded bathroom heater disposed in a bathroom BR. As shown in FIG. 2, the bathroom heater 1 includes a machine body 2 installed so as to be embedded in the ceiling BRa of the bathroom BR, and a lower surface opening of the machine body 2 facing the bathroom BR through an opening opened in the ceiling BRa. And a cover 3 covering from below.

  In the body 2, a ventilation path 6 connecting the suction port 4 and the blowout port 5 provided in parallel with the cover 3 is defined. And the circulation fan 7 which suck | inhales the air in bathroom BR from the suction inlet 4 in the ventilation path 6, and ventilates in the bathroom BR from the blower outlet 5 is arrange | positioned. Further, a heating means 8 is arranged in the ventilation path 6 on the upstream side of the circulation fan 7. The heating means 8 of this embodiment is comprised with the heat radiator which flows the hot water supplied from the heat source machine outside a figure.

  When the heating operation in which the circulation fan 7 and the heating unit 8 are operated together is performed, the air heated by the heating unit 8 is circulated to the bathroom BR by the circulation fan 7 and the bathroom BR is heated. In addition, the blower outlet 5 is provided with a movable louver 9 for changing the blowing direction.

  Further, a spray port 10 is provided in a portion of the cover 3 that is located on the opposite side of the suction port 4 with the blow-out port 5 interposed therebetween. The spray head 11 is arranged on the cover 3 so as to face the spray port 10. Hot water from the heat source machine is supplied to the spray head 11 via the hot water supply pipe 12, and this hot water is ejected from the spray head 11 into the bathroom in the form of a mist. The hot water supply pipe 12 is connected to the spray head 11 via a bellows pipe 12a that can be expanded and contracted in the vertical direction. Therefore, even if the vertical distance between the portion of the hot water supply pipe 12 fixed to the machine body 2 and the spray head 11 changes depending on the plate thickness of the ceiling BRa, this can be absorbed by the expansion and contraction of the bellows pipe 12a.

  The spray head 11 is formed by attaching one or a plurality of spray nozzles 11b to a pipe-shaped main body 11a that is long in the direction perpendicular to the paper surface of FIG. The spray head 11 is rotatable about the axis of the pipe-shaped main body 11a, and the rotation direction of the hot water / water mist can be changed by this rotation.

  Further, the spray port 10 is formed so as to be adjacent to the blowout port 5. Therefore, the spray head 11 will also be arrange | positioned adjacent to the blower outlet 5, and the bathroom heater 1 can be reduced in size. A ventilation fan (not shown) is arranged in the space on the right side in FIG. 2 in the machine body 1 where the hot water supply pipe 12 is arranged so that the air in the bathroom can be discharged to the outside.

  By the way, since it is necessary to provide an inspection port for equipment inspection in the ceiling part directly above the washing place BRb of the bathroom BR, the bathroom heater 1 is installed in the ceiling part directly above the bathtub BRc. In this case, if the blowout port 5 is close to the wall of the bathroom BR and the suction port 4 is located near the washing place BRb, the hot air is not efficiently blown to the washing place BRb, so the blowout port 5 is located near the washing place BRb. I am doing so. Here, if a spray port is provided in the portion of the cover 3 outside the suction port 4 as in the above-described conventional example, it is possible to increase the distance between the washing place BRb, which is a place where a person is present during mist operation, and the spray port. it can. Then, the hot water mist is ejected from the spray head toward the washing place BRb obliquely in the lateral direction, so that the hot water mist reaches the washing place BRb in a sufficiently diffused state, and the hot water mist spreads over the washing place BRb over a wide range.

  However, in this case, when the circulation fan 7 is operated during the mist operation in which the hot water mist is ejected from the spray head, a part of the hot water mist is sucked into the suction port 4 by the suction force of the circulation fan 7 and aggregates as water droplets. The water drops grow and finally drop. However, in this embodiment, since the spraying port 10 is located on the opposite side of the suction port 4 with the blowout port 5 interposed therebetween, the air flow (a in FIG. 1) blown into the bathroom BR from the blowout port 5 is the hot water mist. Functions as an air curtain that divides the air flow (b in FIG. 1) and the air flow sucked into the suction port 4 (c in FIG. 1), and the suction of hot water mist into the suction port 4 is effectively suppressed. The Therefore, there is no problem that the hot water mist sucked into the suction port 4 aggregates and grows as water droplets and drops on a person taking a bath to give unpleasant feeling.

  In the present embodiment, the spray port 10 is located closest to the washing place BRb, and there is a possibility that the hot water mist from the spray head 11 will reach the washing place BRb before it is sufficiently diffused. However, since the spraying port 10 is adjacent to the blowout port 5, the hot water mist can easily ride on the air flow blown from the blowout port 5. And if the blowing direction from the blower outlet 5 is controlled according to the jet direction of the hot water mist from the spray head 11, hot water mist can be spread over the washing area BRb over a wide range.

  As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to this. For example, an electric heater may be used as the heating unit 8 instead of the radiator of the above embodiment.
