Description

  The present invention relates to a bathroom heater with a mist function capable of ejecting mist-like hot water into a bathroom.

  In general, a bathroom heater is a ventilator with a downstream outlet provided in a panel covering the lower surface of the machine body, which is installed so as to be embedded in the ceiling above the bathtub adjacent to the bathroom washing area. A path is defined, and the bathroom is heated by supplying warm air to the bathroom by a heating means and a fan arranged in the ventilation path.

  Conventionally, in such a bathroom heater, a mist nozzle that ejects hot water as a mist is known, and the mist is ejected into the bathroom by the mist nozzle so as to obtain a mist sauna effect (for example, , See Patent Document 1). The mist nozzle projects from the panel at a position different from the outlet.

JP 2006-68130 A

  The above-described conventional mist nozzle protrudes downward from a flat panel along the ceiling surface, so that the mist nozzle becomes conspicuous and is not preferable in appearance.

  Therefore, it is conceivable to improve the appearance quality by making the mist nozzle inconspicuous by arranging the mist nozzle on the inner side surrounded by the inner peripheral edge of the outlet.

  On the other hand, when the washing area is relatively wide, it is necessary to incline the mist nozzle at an angle at which the mist is ejected toward the washing area so that the mist reaches the entire washing area.

  However, if the mist nozzle arranged at the inner periphery of the outlet is tilted in the direction of the washing area, a part of the mist ejected with a spread from the mist nozzle tends to adhere to the inner periphery of the outlet, and in some cases The mist adhering to the inner peripheral edge of the outlet may fall as water droplets, which may cause discomfort to the user during bathing.

  In view of the above points, the present invention prevents the deterioration of the appearance quality due to the provision of the mist nozzle, allows a sufficient amount of mist to be ejected without interfering with the inner peripheral edge of the outlet, and allows a relatively wide washing area. Even if there is, it aims at providing the bathroom heater with a mist function which can spread mist reliably.

In order to achieve such an object, the present invention defines a ventilation path having a downstream outlet provided in a panel covering the lower surface of the machine body as a downstream end in the machine body installed on the ceiling of the bathroom. A bathroom heater in which a heating means and a fan are arranged in a ventilation passage, and a louver provided at the outlet turns to make the wind direction variable and closes the outlet when operation is stopped, and the hot water is mist The mist nozzle is disposed above the lower surface of the panel on the inner side surrounded by the inner peripheral edge of the outlet, and is separated from the louver when the louver opens the outlet. And the outer periphery is surrounded by an exterior member, and the exterior member transmits a part of the airflow passing through the outlet to the inside of the mist nozzle and the outlet. Comprising a guide outlet to derive toward between the edge, the outlet includes an inner peripheral edge of the air outlet on the opposite side to the position of the louvers in a state of opening the air outlet to the mist nozzle, wherein It is formed between the mist nozzles .

  According to the present invention, not only the mist nozzle is disposed inside the outlet, but also the mist nozzle is surrounded by the exterior member so that the exposure of the mist nozzle is very small. Can be prevented.

  Furthermore, by disposing the mist nozzle on the inner side surrounded by the inner peripheral edge of the outlet, the mist can be easily placed on the airflow passing through the outlet, and the mist can be efficiently supplied to the bathroom.

  Moreover, the exterior member can form an air flow between the mist nozzle and the inner peripheral edge of the outlet through the outlet. Thereby, the mist heading from the mist nozzle toward the inner peripheral edge of the outlet port is blocked by the air flow derived from the outlet port, and adhesion to the inner peripheral edge of the outlet port can be prevented.

  In this way, by preventing the mist from adhering to the inner peripheral edge of the outlet, it becomes possible to spread the mist over a wide area. For example, the bathroom heater is installed above the bathtub adjacent to the bathroom washing area. When installed in the mist, the mist can be reliably diffused toward the washing area. Further, since the washing place is relatively wide at this time, even if the mist nozzle is attached to the posture inclined to the washing place, the mist can be prevented from adhering to the inner peripheral edge of the outlet.

  In the present invention, the mist nozzle is disposed within a variable range of the wind direction by the louver.

  According to this, the mist ejected by the mist nozzle can be reliably placed on the airflow directed to the washing place by the louver. Therefore, it is possible to spread the mist over a wide range, and even when the bathroom washing place is relatively wide, it is possible to comfortably perform the mist bath in the washing place.

  Moreover, in this invention, it is preferable that the said mist nozzle is provided in the position which will be in an unexposed state when the said louver which obstruct | occluded the said blower outlet covers. According to this, when the operation is stopped, the mist nozzle is reliably hidden by the louver, and it is possible to reliably prevent the appearance quality from being deteriorated by the mist nozzle.

The figure which shows a bathroom typically. Explanatory sectional drawing which shows the structure of the bathroom heater with a mist function. The figure which shows the panel of the bathroom heater with a mist function. Explanatory sectional drawing which shows a mist nozzle. FIG.

  An embodiment of the present invention will be described with reference to the drawings. As illustrated in FIG. 1, a bathroom heater 1 with a mist function (hereinafter simply referred to as a bathroom heater 1) according to the present embodiment is disposed on a ceiling Ya of a bathroom Y. The bathroom Y includes a washing place Yb and a bathtub Yc.

  As shown in FIGS. 1 and 2, the bathroom heater 1 has a machine body 2 attached so as to be embedded in the ceiling Ya of the bathroom Y and a lower surface of the machine body 2 facing the bathroom Y through an opening opened in the ceiling Ya. And a panel 3 covering from the lower side of Ya.

  As shown in FIG. 3, the suction inlet 4 and the outlet 5 are both formed downward on the panel 3. The blowout port 5 is formed in a horizontally long rectangular shape, and the blowout port 5 is provided with a louver 6 having a shape corresponding to the blowout port 5.

  The louver 6 includes rotating shafts 6a on both sides in the longitudinal direction corresponding to the shape of the outlet 5, and the rotating shaft 6a is rotated by a driving device such as a motor (not shown). By rotating the louver 6, the blowing direction of the outlet 5 can be directed to the washing area Yb. Further, the louver 6 can be in a state in which the outlet 5 is closed when the heating operation is stopped. FIG. 3 shows a state where the louver 6 closes the outlet 5.

  As shown in FIG. 2, a ventilation path 7 is defined in the body 2. The ventilation path 7 connects the inlet 4 and the outlet 5 with the inlet 4 as an upstream end and the outlet 5 as a downstream end.

  The ventilation path 7 is provided with a fan 8 and a heating means 9. The fan 8 sucks air in the bathroom Y from the suction port 4 and forms an air flow along the ventilation path 7. The heating means 9 is comprised with the heat radiator which flows the warm water supplied from the heat source machine outside a figure. When the heating operation for operating both the fan 8 and the heating means 9 is performed, the air heated by the heating means 9 is circulated to the bathroom Y by the fan 8 and the bathroom Y is heated.

  As shown in FIGS. 2 and 4, a mist nozzle 10 and an exterior member 11 that surrounds the mist nozzle 10 are provided inside the outlet 5. The mist nozzle 10 is in a state (non-exposed state) covered with the louver 6 when the outlet 5 is closed by the louver 6. Thereby, when the operation is stopped, it is possible to reliably prevent the appearance quality from being deteriorated by the mist nozzle 10.

  Hot water from the heat source machine is supplied to the mist nozzle 10 via the hot water supply pipe 12. The mist nozzle 10 ejects hot water from the hot water supply pipe 12 in a mist form.

  By the way, in general, an inspection port (not shown) for equipment inspection is provided on the ceiling Ya just above the washing place Yb of the bathroom Y. The bathroom heater 1 is installed on the ceiling directly above the bathtub Yc so as not to block the inspection port.

  In this case, if the outlet 5 is located near the wall of the bathroom Y and the inlet 4 is located near the washing place Yb, the inlet 4 is located between the outlet 5 and the washing place Yb. The hot air is not efficiently delivered to the washing place Yb. Therefore, the bathroom heater 1 is installed such that the outlet 5 is located near the washing place Yb, and the rotation shaft 6a of the louver 6 is located along the inner peripheral edge of the outlet 5 opposite to the washing place Yb. .

  The mist nozzle 10 is located on the inner side surrounded by the inner peripheral edge of the outlet 5 and closer to the washing place Yb than the rotation shaft 6a of the louver 6, thereby being disposed within the variable range of the wind direction by the louver 6. Has been.

  Furthermore, the mist nozzle 10 is disposed inside the outlet 5 with an inclination of a predetermined angle (about 30 ° in the present embodiment) in the direction of the washing place Yb with respect to the vertical direction. The inclination angle of the mist nozzle 10 is set to such an angle that the mist sufficiently reaches the washing place Yb in a state where the mist is diffused and the mist reaches every corner of the washing place Yb. Since the mist is ejected with a relatively large spread angle, when the mist sufficiently reaches every corner of the washing place Yb (for example, when the washing place Yb is relatively narrow), the mist nozzle 10 is not tilted vertically. You may provide in the attitude | position facing downward.

  Further, since the mist nozzle 10 is provided closer to the washing place Yb than the rotating shaft 6a of the louver 6, the warm air guided by the louver 6 can function as an air curtain. Therefore, not only can the mist directed toward the bathtub Yc be reduced, but a sufficient amount of mist can be supplied toward the washing place Yb by placing the mist on the warm air guided by the louver 6.

  Further, as shown in FIGS. 4 and 5, since the exterior member 11 surrounds the mist nozzle 10, adhesion of mist to the inner peripheral edge of the outlet 5 is also prevented.

  The exterior member 11 includes a nozzle surrounding portion 13 that surrounds the mist nozzle 10, and a connecting portion 14 that is connected to the inner peripheral edge of the outlet 5 and is attached. A gap is formed between the nozzle surrounding portion 13 and the outer peripheral surface of the mist nozzle 10. A part of the airflow from the outlet 5 passes through this gap.

  And the clearance gap 15 between the connection part 14 of the exterior member 11 and the outer peripheral surface of the mist nozzle 10 is a part of the airflow which passes the blower outlet 5, and the inner periphery (specifically mist nozzle 10 is mist nozzle 10). Derived between the mist nozzle 10 and the edge on the facing side. The gap 15 functions as a lead-out port of the present invention, and is larger than the other gaps between the nozzle surrounding portion 13 and the mist nozzle 10.

  Since the mist ejected from the mist nozzle 10 has a relatively large spread angle (for example, 70 ° to 80 °), a part of the mist is directed toward the inner peripheral edge of the outlet 5. When the mist nozzle 10 is inclined toward the washing place Yb in the vicinity of the inner peripheral edge of the outlet 5 as in the present embodiment, more mist is directed toward the inner peripheral edge of the outlet 5. At this time, the mist from the mist nozzle 10 toward the inner periphery of the outlet 5 is blocked by a part of the warm air derived from the gap 15 (outlet) of the exterior member 11. Thereby, adhesion of the mist to the inner peripheral edge of the blowout port 5 is almost eliminated, and it is possible to prevent the mist attached to the inner peripheral edge of the blowout port 5 from falling as a water droplet.

  Further, since the mist nozzle 10 is not only located inside the outlet 5 but also surrounded by the exterior member 11, the mist nozzle 10 is hardly noticeable in appearance, so that the mist nozzle 10 does not deteriorate the appearance quality. .

  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 means 9 instead of the radiator of the above embodiment.
