Description

本発明は、浴室を高温多湿のサウナ状態にすることが可能なサウナ機能付き浴室暖房機に関する。   The present invention relates to a bathroom heater with a sauna function that can make a bathroom in a hot and humid sauna state.

浴室暖房機は、一般的に、浴室に連通する吸込み口と吹出し口とを開設した暖房機本体を備えている。そして、暖房機本体内に、吸込み口と吹出し口とを結ぶ通風路を画成し、通風路に、浴室内の空気を吸込み口から吸込んで吹出し口から浴室に吹出す循環ファンを設けると共に、循環ファンより上流側の通風路の部分に、吸込み口から吸込まれた空気を加熱する加熱器を設けている。   The bathroom heater generally includes a main body of a heater having a suction port and a blowout port that communicate with the bathroom. And, in the main body of the heater, a ventilation path connecting the inlet and the outlet is defined, and a circulation fan that sucks air in the bathroom from the inlet and blows out from the outlet to the bathroom is provided in the ventilation path, A heater for heating the air sucked from the suction port is provided in the portion of the ventilation path upstream of the circulation fan.

また、このような浴室暖房機において、給湯路を介して供給される温水を循環ファンに向けて噴霧するミストノズルを設けたものも知られている(例えば、特許文献1参照)。このものでは、ミストノズルから噴霧された温水が循環ファンに衝突して微細水滴に破砕され、循環ファンから送り出される空気に微細水滴が混入される。そのため、空気が加湿されて浴室が高温多湿のサウナ状態になる。   In addition, such a bathroom heater is also known in which a mist nozzle is provided that sprays hot water supplied via a hot water supply channel toward a circulation fan (see, for example, Patent Document 1). In this, the hot water sprayed from the mist nozzle collides with the circulation fan and is crushed into fine water droplets, and the fine water droplets are mixed into the air sent out from the circulation fan. Therefore, the air is humidified and the bathroom is in a hot and humid sauna state.

然し、上記従来例では、サウナ運転をある程度継続すると、循環ファンがミストノズルから噴霧される温水で濡れた状態になる。そのため、循環ファンに付着した水膜が大きな水滴となって飛散し、この水滴が吹出し口から浴室内に飛び出して使用者に当り、不快感を与えてしまうことがある。

However, in the above conventional example, when the sauna operation is continued to some extent, the circulation fan becomes wet with the hot water sprayed from the mist nozzle. Therefore, the water film adhering to the circulation fan is scattered as large water droplets, and the water droplets may jump out from the outlet into the bathroom, hitting the user and giving an uncomfortable feeling.
JP 2006-25964 A

本発明は、以上の点に鑑み、大きな水滴が浴室内に飛び出すことを防止できるようにしたサウナ機能付き浴室暖房機を提供することをその課題としている。   This invention makes it the subject to provide the bathroom heater with a sauna function which enabled it to prevent that a big water droplet jumps out in a bathroom in view of the above point.

上記課題を解決するために、本発明は、浴室に連通する吸込み口と吹出し口とを開設した暖房機本体内に、吸込み口と吹出し口とを結ぶ通風路を画成し、通風路に、浴室内の空気を吸込み口から吸込んで吹出し口から浴室に吹出す循環ファンを設けると共に、循環ファンより上流側の通風路の部分に、吸込み口から吸込まれた空気を加熱する加熱器を設けたサウナ機能付き浴室暖房機であって、給湯路を介して供給される温水を微細水滴に破砕して通風路に流れる空気に混入させることにより空気を加湿する加湿手段を備えるものにおいて、加熱器と循環ファンとの間の通風路の部分に加湿手段が配置されていることを特徴とする。   In order to solve the above-mentioned problems, the present invention defines a ventilation path connecting the suction inlet and the outlet in the heater body in which the inlet and the outlet connected to the bathroom are opened, A circulation fan that sucks air in the bathroom from the suction port and blows it out of the blower port to the bathroom, and a heater that heats the air sucked from the suction port is provided in the part of the ventilation path upstream of the circulation fan. A bathroom heater with a sauna function, comprising heating means for humidifying air by crushing hot water supplied via a hot water supply path into fine water droplets and mixing it with air flowing through a ventilation path, Humidification means is arranged in the portion of the ventilation path between the circulation fan.

本発明によれば、加湿手段により発生する微細水滴が加熱器と循環ファンとの間の通風路の部分に流れる空気に混入される。ここで、加熱器と循環ファンとの間の通風路の部分は負圧になり、且つ、当該部分に流れる空気は加熱器で加熱されているため、微細水滴が効率良く気化し、循環ファンが水で濡れることを防止できる。従って、循環ファンから大きな水滴が飛散して浴室内に飛び出すことを防止できる。   According to the present invention, fine water droplets generated by the humidifying means are mixed into the air flowing in the portion of the ventilation path between the heater and the circulation fan. Here, the portion of the ventilation path between the heater and the circulation fan has a negative pressure, and the air flowing through the portion is heated by the heater. Can prevent getting wet with water. Therefore, it is possible to prevent large water droplets from splashing from the circulation fan and jumping into the bathroom.

また、本発明においては、加熱器と循環ファンとの間の通風路の部分に下方への窪み部が設けられ、この窪み部に加湿手段が配置されることが望ましい。これによれば、循環ファンと加湿手段との間に高低差が確保され、そのため、加湿手段で発生する水滴のうち比較的粒径の大きなものは循環ファンに吸込まれる前に自重で落下して、気化しやすい微細な水滴のみが循環ファンに吸込まれるようになる。従って、循環ファンが水で濡れることを一層確実に防止できる。更に、通風路に流れる空気流に対して加湿手段が抵抗にならず、暖房効率を低下させることなく加湿することができる。   Moreover, in this invention, it is desirable to provide the downward hollow part in the part of the ventilation path between a heater and a circulation fan, and to arrange a humidification means in this hollow part. According to this, a difference in height is ensured between the circulation fan and the humidification means, and therefore, water droplets generated by the humidification means that have a relatively large particle size fall by their own weight before being sucked into the circulation fan. Thus, only fine water droplets that are easily vaporized are sucked into the circulation fan. Therefore, it is possible to more reliably prevent the circulation fan from getting wet with water. Further, the humidifying means does not become resistant to the airflow flowing through the ventilation path, and humidification can be performed without reducing the heating efficiency.

図1は本発明の実施形態のサウナ機能付き浴室暖房機を示している。この浴室暖房機は、浴室の天井部に設置される箱形の暖房機本体1を備えている。暖房機本体1は、浴室の天井内面に露出する下カバー2を具備しており、この下カバー2に吸込み口3と吹出し口4とが開設されている。   FIG. 1 shows a bathroom heater with a sauna function according to an embodiment of the present invention. The bathroom heater includes a box-shaped heater body 1 installed on the ceiling of the bathroom. The heater body 1 includes a lower cover 2 exposed on the ceiling inner surface of the bathroom, and a suction port 3 and an outlet 4 are opened in the lower cover 2.

暖房機本体1内には、吸込み口3と吹出し口4とを結ぶ通風路5が画成されている。そして、通風路5に循環ファン6を配置すると共に、循環ファン6より上流側の通風路5の部分に、図外の熱源機からの熱媒体(水、不凍液等)を供給する熱交換器から成る加熱器7を設けている。加熱器7に熱媒体を供給すると共に循環ファン6を作動させると、浴室内の空気が吸込み口3から吸込まれて加熱器7で加熱され、吹出し口4から温風となって浴室内に送風される。   In the heater body 1, a ventilation path 5 that connects the suction port 3 and the outlet 4 is defined. And from the heat exchanger which arrange | positions the circulation fan 6 in the ventilation path 5, and supplies the heat medium (water, antifreezing liquid, etc.) from the heat source apparatus outside a figure to the part of the ventilation path 5 upstream from the circulation fan 6. A heater 7 is provided. When the heating medium is supplied to the heater 7 and the circulation fan 6 is operated, the air in the bathroom is sucked from the suction port 3 and heated by the heater 7, and warm air is blown from the outlet 4 into the bathroom. Is done.

また、加熱器7と循環ファン6との間の通風路5の部分には下方への窪み部5aが設けられている。そして、この窪み部5aに加湿手段8を配置している。加湿手段8は、図2に示す如く、ドレンパン81と、ドレンパン81内に傾斜姿勢で配置した衝突板82と、給湯路83を介して供給される温水を衝突板82に向けて噴出するノズル84とを備えている。ノズル84は複数個(図示例では3個)設けられており、各ノズル84に各別の電磁開閉弁85を介して温水が供給される。また、図1に示す如くドレンパン81用の排水ポンプ86が設けられている。   Further, a downwardly recessed portion 5 a is provided in the portion of the ventilation path 5 between the heater 7 and the circulation fan 6. And the humidification means 8 is arrange | positioned in this hollow part 5a. As shown in FIG. 2, the humidifying means 8 includes a drain pan 81, a collision plate 82 disposed in an inclined posture in the drain pan 81, and a nozzle 84 that ejects hot water supplied via the hot water supply path 83 toward the collision plate 82. And. A plurality of nozzles 84 (three in the illustrated example) are provided, and hot water is supplied to each nozzle 84 via a separate electromagnetic on-off valve 85. Further, as shown in FIG. 1, a drain pump 86 for the drain pan 81 is provided.

尚、ノズル84には給湯機からの温水を供給してもよく、また、熱源機からの熱媒体を供給する液々熱交換器で加熱された温水を供給してもよい。   The nozzle 84 may be supplied with hot water from a water heater, or may be supplied with hot water heated by a liquid heat exchanger that supplies a heat medium from a heat source device.

次に、本実施形態の作動について説明する。図外のリモコンに設けられたサウナスイッチをオンすると、加熱器7に熱源機からの熱媒体が供給されると共に循環ファン6が駆動され、更に、電磁開閉弁85が開弁してノズル84から温水が噴出する。噴出した温水は衝突板82に衝突して破砕される。そして、衝突板82から跳ね上がる微細水滴が加熱器7と循環ファン6との間の通風路5の部分に流れる空気に混入する。これにより空気中の湿度が高くなり、浴室内が高温多湿のサウナ状態になる。尚、衝突板82で破砕されずに流下する温水はドレンパン81で回収され、排水ポンプ86により適宜排水される。   Next, the operation of this embodiment will be described. When the sauna switch provided in the remote controller (not shown) is turned on, the heat medium from the heat source device is supplied to the heater 7 and the circulation fan 6 is driven. Further, the electromagnetic opening / closing valve 85 is opened and the nozzle 84 is opened. Hot water erupts. The ejected hot water collides with the collision plate 82 and is crushed. Then, fine water droplets jumping from the collision plate 82 are mixed into the air flowing in the portion of the ventilation path 5 between the heater 7 and the circulation fan 6. As a result, the humidity in the air becomes high, and the bathroom is in a hot and humid sauna state. The hot water flowing down without being crushed by the collision plate 82 is collected by a drain pan 81 and appropriately drained by a drain pump 86.

ここで、加熱器7と循環ファン6との間の通風路5の部分は負圧になり、且つ、当該部分に流れる空気は加熱器7で加熱されているため、この空気に混入した微細水滴は効率良く気化される。従って、循環ファン6が水で濡れることを防止できる。そのため、循環ファン6が水で濡れた場合に生ずる不具合、即ち、循環ファン6から大きな水滴が飛散し、この水滴が浴室内に飛び出して使用者に当り、不快感を与えることを防止できる。   Here, the portion of the ventilation path 5 between the heater 7 and the circulation fan 6 has a negative pressure, and the air flowing through the portion is heated by the heater 7, so that fine water droplets mixed in the air Is efficiently vaporized. Therefore, it is possible to prevent the circulation fan 6 from getting wet with water. Therefore, it is possible to prevent a problem that occurs when the circulation fan 6 gets wet with water, that is, large water droplets scatter from the circulation fan 6, and the water droplets jump out into the bathroom and hit the user and give discomfort.

特に、本実施形態では、加熱器7と循環ファン6との間の通風路5の部分に設けた下方への窪み部5aに加湿手段8を配置することで、循環ファン6と加湿手段8との間に高低差が確保される。そのため、衝突板82から比較的大きな粒径の水滴が跳ね上がっても、この水滴は循環ファン6に吸込まれる前に自重で落下し、循環ファン6に吸込まれるのは気化しやすい微細水滴のみになる。これにより、循環ファン6が水で濡れることを一層確実に防止できる。更に、通風路5に流れる空気流に対して加湿手段8が抵抗にならず、暖房効率を低下させることなく加湿することができる。   In particular, in the present embodiment, the humidifying means 8 is disposed in the downwardly recessed portion 5a provided in the portion of the ventilation path 5 between the heater 7 and the circulation fan 6, so that the circulation fan 6 and the humidification means 8 are A height difference is ensured between the two. Therefore, even if a water droplet having a relatively large particle size jumps up from the collision plate 82, the water droplet falls by its own weight before being sucked into the circulation fan 6, and only fine water droplets that are easily vaporized are sucked into the circulation fan 6. become. Thereby, it can prevent more reliably that the circulation fan 6 gets wet with water. Furthermore, the humidifying means 8 does not become resistant to the airflow flowing through the ventilation path 5, and humidification can be performed without reducing heating efficiency.

また、1個のノズル84から多量の温水を噴出したのでは、衝突板82への衝突により微細水滴を効率良く発生できなくなる。これに対し、本実施形態では、ノズル84を複数個設けるため、ノズル1個当りの噴出水量を少なくして、微細水滴を効率良く発生させることができる。更に、温水を噴出するノズル84の個数を可変することで、加湿量を調節することも可能になる。   Also, if a large amount of hot water is ejected from one nozzle 84, fine water droplets cannot be generated efficiently due to collision with the collision plate 82. On the other hand, in this embodiment, since a plurality of nozzles 84 are provided, the amount of water ejected per nozzle can be reduced, and fine water droplets can be generated efficiently. Further, the amount of humidification can be adjusted by changing the number of nozzles 84 that eject hot water.

以上、本発明の実施形態について図面を参照して説明したが、本発明はこれに限定されない。例えば、上記実施形態では、加熱器7として熱源機からの熱媒体を供給する熱交換器を用いたが、電気ヒータを用いることも可能である。また、上記実施形態の加湿手段8は、ノズル84から噴出する温水を衝突板82に衝突させて微細水滴に破砕する型式に構成されているが、回転板に温水を衝突させる等の他の型式のものを用いることも可能である。また、ノズル84としては、温水を水流状に噴出するものやミスト状に噴出するものを用いることができる。   As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to this. For example, in the above embodiment, a heat exchanger that supplies a heat medium from a heat source machine is used as the heater 7, but an electric heater can also be used. Further, the humidifying means 8 of the above-described embodiment is configured in such a manner that the hot water ejected from the nozzle 84 collides with the collision plate 82 and is crushed into fine water droplets, but other types such as causing the hot water to collide with the rotating plate. It is also possible to use. Moreover, as the nozzle 84, the thing which ejects warm water in the shape of a water stream, or the thing which ejects in a mist form can be used.
