Description

本発明は、加熱装置として輻射熱を利用して浴室暖房を行う浴室暖房機に関する発明である。   The present invention relates to a bathroom heater that performs bathroom heating using radiant heat as a heating device.

従来の浴室暖房機としては浴室の天井や壁面に設置した温風式の浴室暖房機が知られている。この温風式の浴室暖房機は、暖房機内部に備えられた送風機によって浴室内の空気を吸い込み、その吸い込んだ空気を加熱手段、たとえば電気ヒータで温めて再び浴室内へ温風として供給するものが知られている。   As a conventional bathroom heater, a hot air type bathroom heater installed on the ceiling or wall of a bathroom is known. This warm air type bathroom heater sucks air in the bathroom with a blower provided inside the heater, warms the sucked air with a heating means such as an electric heater, and supplies it as warm air into the bathroom again. It has been known.

しかしこのような場合、入浴者が浴室に入る前段階としての室内事前暖房には好適であるが、入浴者が浴室に居る場合にはこの温風が直接入浴者の肌にあたり、体感温度を下げて快適感を損なってしまうという問題があった。   However, in such a case, it is suitable for indoor preheating as a step before the bather enters the bathroom, but when the bather is in the bathroom, this warm air directly hits the skin of the bather and lowers the sensory temperature. There was a problem that the feeling of comfort was impaired.

そこで近年では輻射熱を利用した浴室暖房機が知られている。この輻射式浴室暖房機は浴室内を臨む位置に遠赤外線式の電気ヒータ(例えば、カーボランプヒータ)を搭載して、反射板によって浴室内に居る入浴者に向けて輻射熱を供給するものである。しかしながらこの輻射熱を利用した浴室暖房機の場合、使用するカーボンランプヒータから発生する熱により反射板や暖房機内部を構成している樹脂が熱変形を起こし、浴室暖房機の機能や性能に悪影響を与える可能性があるという問題があった。   In recent years, therefore, bathroom heaters using radiant heat have been known. This radiant bathroom heater is equipped with a far-infrared electric heater (for example, a carbon lamp heater) at a position facing the bathroom, and supplies radiant heat to a bather in the bathroom with a reflector. . However, in the case of a bathroom heater that uses this radiant heat, the heat that is generated from the carbon lamp heater that is used causes heat deformation of the reflector and the resin that makes up the interior of the heater, which adversely affects the function and performance of the bathroom heater. There was a problem that could give.

上記問題を解決するために、暖房機内部に備えた送風機により輻射熱で暖房している時には送風機を作動して機器内部を冷却するという方法が考えられる。(例えば、特許文献1参照。)。   In order to solve the above-mentioned problem, a method of operating the blower to cool the inside of the device when heating with radiant heat by the blower provided inside the heater can be considered. (For example, refer to Patent Document 1).

しかし、この場合は輻射熱で暖房しているときは常に冷却用として送風機を作動しているため入浴中に送風機の作動音が不快に感じたり、特に運転開始直後や外気温度が低い場合は冷却用の風が身体に当たると肌寒く感じるという問題があった。   However, in this case, the air blower is always operated for cooling when it is heated by radiant heat, so the operating sound of the air blower feels uncomfortable during bathing, especially when the outside air temperature is low immediately after the start of operation. When the wind hits the body, there was a problem that it felt chilly.

図1は、本発明の浴室暖房機を浴室に設置した実施例1を示す図である。   FIG. 1 is a diagram showing Example 1 in which the bathroom heater of the present invention is installed in a bathroom.

略箱状の本体ケースを有する浴室暖房機1は浴室の壁Aに設置され、壁Aに設置された浴室暖房機1の前面下方には、カーボンランプヒータ5と反射板7とからなる加熱機が配設させている。反射板7はアルミ等の金属の板状体で湾曲部と両側面部とからなる外郭が略蒲鉾状に形成されたもので、湾曲部を入浴者に直接輻射熱があたるように壁側方向に向け、略蒲鉾状に外郭を囲われた空洞部を前方へ向けて配設されており、反射板7の空洞部にはカーボンランプヒータ5が両端を反射板7の両側面部に嵌合固定されて、本体ケースの長手方向に沿って間隔をあけて2本並設されている。また、カーボンランプヒータ5の前面には、指侵入防止としての金属製の線材11が複数並設されている。   A bathroom heater 1 having a substantially box-shaped main body case is installed on a wall A of the bathroom, and a heater comprising a carbon lamp heater 5 and a reflector 7 below the front of the bathroom heater 1 installed on the wall A. Is arranged. The reflector 7 is a plate-like body made of a metal such as aluminum and has an outer wall made up of a curved portion and both side portions, and the curved portion is directed in the direction of the wall so that the bather is directly exposed to radiant heat. The hollow portion surrounded by the outer shape in a generally bowl shape is arranged facing forward, and the carbon lamp heater 5 is fitted and fixed to both side portions of the reflecting plate 7 at both ends in the hollow portion of the reflecting plate 7. The two are arranged in parallel along the longitudinal direction of the main body case with a space therebetween. In addition, a plurality of metal wires 11 are arranged in parallel on the front surface of the carbon lamp heater 5 to prevent finger penetration.

さらに浴室暖房機1前面のカーボンランプヒータ5及び反射板7近傍の上部および下部には、浴室内の空気を吸い込むための吸込口3a、3bが略長方形で開口され、反射板7の長手方向に一列にそれぞれ複数個配設されている。また、さらに浴室暖房機1の下部で且つ壁面に近い位置に、吸込口3a、3bから吸込んだ空気を再び浴室に吹出すための吹出口9を備えている。   Furthermore, in the upper part and the lower part in the vicinity of the carbon lamp heater 5 and the reflector 7 on the front surface of the bathroom heater 1, suction ports 3 a and 3 b for taking in the air in the bathroom are opened in a substantially rectangular shape, and in the longitudinal direction of the reflector 7. A plurality of lines are arranged in a row. In addition, an air outlet 9 is provided in the lower part of the bathroom heater 1 and at a position close to the wall surface to blow out the air sucked from the air inlets 3a and 3b into the bathroom again.

図2は、本発明の実施例1に係る浴室暖房機の断面図である。   FIG. 2 is a cross-sectional view of the bathroom heater according to the first embodiment of the present invention.

浴室暖房機1内部には、吸込口3a、3bから浴室内の空気を吸い込み、吹出口9から再び浴室内に吹出すためのモータ15の駆動により作動する送風ファン13を備えている。送風ファン13は反射板7の背面側上方に配設され、浴室暖房機1内部は、送風ファン13を配置した部分とカーボンランプヒータ5及び反射板7を配置した部分とに、送風ファン13の吸気口を連通させて2つに区画されており、区画により吸込口3a、3bと送風ファン13とを結ぶ空気の通路として吸気通風路17aが形成され、送風ファン13と吹出口9とを結ぶ空気の通路として排気通風路17bが形成されている。   Inside the bathroom heater 1, there is provided a blower fan 13 that operates by driving a motor 15 for sucking air in the bathroom from the inlets 3 a and 3 b and blowing it out from the outlet 9 into the bathroom again. The blower fan 13 is disposed on the upper rear side of the reflector 7, and the interior of the bathroom heater 1 is divided into a portion where the blower fan 13 is disposed and a portion where the carbon lamp heater 5 and the reflector 7 are disposed. The intake port communicates and is divided into two, and the intake air passage 17a is formed as an air passage connecting the suction ports 3a, 3b and the blower fan 13 by the partition, and the blower fan 13 and the blower outlet 9 are connected. An exhaust ventilation path 17b is formed as an air passage.

さらには反射板7の後方背面の吸気通風路17aには温度検出手段としての温度センサ19も備えられている。また、カーボンランプヒータ5及び前述した送風ファン13の作動は図示しない制御部によってコントロールされる。   Further, a temperature sensor 19 as a temperature detecting means is provided in the intake ventilation path 17a on the rear rear surface of the reflecting plate 7. The operation of the carbon lamp heater 5 and the blower fan 13 is controlled by a control unit (not shown).

この構成において、図示せぬスイッチにより暖房運転が指示されたとき、制御部でカーボンランプヒータ5に通電が開始される。これにより入浴者は輻射式の暖をとることができる。また、カーボンランプヒータ5に通電されている間、制御部では、温度センサ19の検出温度と予め設定された浴室暖房機の内部を構成する樹脂の熱変形点を定めた設定温度とを継続して比較している。
温度センサ19の検出温度が予め定めた設定温度(例えば60℃)より高い温度を検出した場合、制御部は送風ファン13を作動させる。これにより吸込口3a及び吸込口3bから浴室内の空気を吸い込み、吸込口3aから吸い込まれた空気は反射板7裏面の通風路17aの上部を、吸込口3bから吸い込まれた空気は反射板7裏面の通風路17aの下部を通って送風ファン13に吸い込まれる(図中矢印)。
In this configuration, when the heating operation is instructed by a switch (not shown), the controller starts energization of the carbon lamp heater 5. Thereby, the bather can take a radiant warm. Further, while the carbon lamp heater 5 is energized, the control unit continues the temperature detected by the temperature sensor 19 and a preset temperature that defines a preset thermal deformation point of the resin that constitutes the interior of the bathroom heater. Compare.
When the temperature detected by the temperature sensor 19 detects a temperature higher than a preset temperature (for example, 60 ° C.), the control unit activates the blower fan 13. Thereby, the air in the bathroom is sucked from the suction port 3a and the suction port 3b, the air sucked from the suction port 3a is above the ventilation path 17a on the back surface of the reflection plate 7, and the air sucked from the suction port 3b is the reflection plate 7. The air is sucked into the blower fan 13 through the lower part of the ventilation path 17a on the back surface (arrow in the figure).

このとき、吸込口3aから送風ファン13で吸い込んだ空気を反射板7上部を通過させることで、カーボンランプヒータ5の作動で発生した反射板7上部の浴室暖房機1内部に上昇した熱を送風ファン13へ流出されることで反射板7上部に滞留する熱を取り除き、浴室暖房機1内部を冷却すると共に、吹出口9から温風として吹出し、また、吸込口3bから送風ファン13で吸い込んだ空気を反射板7裏面を通過させることで、カーボンランプヒータ5の作動で発生した反射板7裏面の浴室暖房機1内部に滞留する熱を送風ファン13へ流出されることで反射板7裏面に滞留する熱を取り除き、浴室暖房機1内部を冷却すると共に、吹出口9から温風として吹出すようになっている。   At this time, the air sucked by the blower fan 13 from the suction port 3 a is passed through the upper part of the reflector 7, so that the heat rising inside the bathroom heater 1 above the reflector 7 generated by the operation of the carbon lamp heater 5 is blown. The heat accumulated in the upper part of the reflection plate 7 is removed by being discharged to the fan 13, the interior of the bathroom heater 1 is cooled, the hot air is blown out from the air outlet 9, and the air is sucked in from the air inlet 3 b by the blower fan 13. By allowing air to pass through the back surface of the reflecting plate 7, the heat accumulated in the bathroom heater 1 on the back surface of the reflecting plate 7 generated by the operation of the carbon lamp heater 5 flows out to the blower fan 13, and then flows to the back surface of the reflecting plate 7. The accumulated heat is removed, the interior of the bathroom heater 1 is cooled, and the hot air is blown out from the air outlet 9.

吹出口9から吹出された温風は、反射板7の裏面の通風路17aを通過した空気が送風ファンを経由し吹出されたもので、樹脂の熱変形起点を定めた温度に近い温度(例えば60℃)のため、温風としては入浴者にとって充分に温かく感じる。更に、送風ファン13の温風の強さを選択可能とし、制御部にて回転数を低くし温風の強さを弱くするよう設定すれば入浴者の身体に当たっても肌寒さを感じない温度となる。
ここで、送風ファン13が作動後は、浴室暖房機1内部は冷却され温度センサ19の検出温度は低下するが、このとき、温度センサ19の検出温度が浴室暖房機1の内部を構成する樹脂の熱変形起点を定めた設定温度(例えば60℃)に対して熱変形を阻止するに充分に安全な温度を定めた第2設定温度(例えば55℃)を検出すると、送風ファン13の作動を停止することで、再び送風ファンの作動音がない快適な入浴を実現できるように構成している。
また、送風ファン13が作動後も浴室暖房機1内部は冷却されず温度センサ19の検出温度が浴室暖房機1の内部を構成する樹脂の熱変形起点を設定温度(例えば60℃)を超え熱変形を阻止が不可となる温度を定めた第3設定温度(例えば80℃)を検出すると、例えば送風ファン13が作動していない等の異常であると判断し、カーボンランプ5及び送風ファン13の作動を停止することで、安全に浴室暖房機1の作動を全停止するように構成している。
尚、第2設定温度および第3設定温度は、センサーのばらつき幅および送風ファンの起動停止の頻度幅を含ませて設定されている。
The warm air blown out from the air outlet 9 is the air that has passed through the ventilation path 17a on the back surface of the reflecting plate 7 and is blown out through the blower fan. The temperature is close to the temperature that determines the thermal deformation starting point of the resin (for example, 60 ° C), the warm air feels warm enough for bathers. Furthermore, if the strength of the warm air of the blower fan 13 can be selected and the control unit is set to reduce the rotation speed and weaken the strength of the warm air, the temperature does not feel chill even when hitting the body of the bather. Become.
Here, after the blower fan 13 is activated, the interior of the bathroom heater 1 is cooled and the temperature detected by the temperature sensor 19 is lowered. At this time, the temperature detected by the temperature sensor 19 is a resin constituting the interior of the bathroom heater 1. When a second set temperature (for example, 55 ° C.) that sets a temperature sufficiently safe to prevent thermal deformation is detected with respect to a set temperature (for example, 60 ° C.) that determines the starting point of heat deformation of By stopping, it is configured so that comfortable bathing without the operation sound of the blower fan can be realized again.
Further, even after the blower fan 13 is activated, the interior of the bathroom heater 1 is not cooled, and the temperature detected by the temperature sensor 19 exceeds the set temperature (for example, 60 ° C.) by exceeding the thermal deformation starting point of the resin constituting the interior of the bathroom heater 1. When a third set temperature (for example, 80 ° C.) that determines the temperature at which the deformation cannot be prevented is detected, it is determined that there is an abnormality such as the blower fan 13 not operating, and the carbon lamp 5 and the blower fan 13 By stopping the operation, the operation of the bathroom heater 1 is safely stopped.
The second set temperature and the third set temperature are set so as to include the variation width of the sensor and the frequency range of the start and stop of the blower fan.

以上の構成により、必要な場合のみ送風ファンを作動することにより送風ファンが作動する時間を極力なくすことができ、省エネルギー化が図られる。また、暖房運転時に送風ファンを回転させて入浴者が感じる作動音の不快な思いを緩和することができる。また、送風ファン作動時には浴室暖房機1内部が冷却されるため、カーボンランプヒータから発生する熱による、反射板や暖房機内部を構成している樹脂が熱変形を起こすことを防止することができる。更に、冷却用の風も入浴者の身体に当たることによる肌寒さも緩和することができる。   With the above configuration, by operating the blower fan only when necessary, the time for which the blower fan is operated can be eliminated as much as possible, thereby saving energy. Moreover, the unpleasant feeling of the operation sound which a bather feels by rotating a ventilation fan at the time of heating operation can be relieved. In addition, since the interior of the bathroom heater 1 is cooled when the blower fan is activated, it is possible to prevent the heat forming from the carbon lamp heater from causing thermal deformation of the resin constituting the reflector and the interior of the heater. . Furthermore, the chill caused by the cooling air hitting the bather's body can be alleviated.

図3は、本発明の実施例1に係る動作フローチャートを示す図である。   FIG. 3 is a diagram illustrating an operation flowchart according to the first embodiment of the present invention.

この輻射熱による暖房運転時の制御においては、暖房運転が開始するとカーボンランプヒータ5がON(通電)する(ステップS1)。次に暖房運転停止の指示がない間(ステップS2)は、温度センサ19による検出温度が設定温度t1(例えば60度)よりも低い場合はカーボンランプヒータ5の通電を継続するが、検出温度が設定温度t1以上の場合には、図示せぬ制御部からの指令により送風ファン13が作動する(ステップS4)。そして、暖房運転停止の指示がない間(ステップS5)は、温度センサ19の温度が設定温度t1よりも所定温度低い第2設定温度t2以下(例えば55度)になったか否かを判断する(ステップS6)。第2設定温度t2以下になれば送風ファン13を停止させるが(ステップS7)、第2設定温度t2よりも高ければ今度は温度センサ19の温度が設定温度t1よりも所定温度高い第3設定温度t3以上(例えば80度)か否かを判断する(ステップS8)。温度センサ19の温度が第3設定温度t3よりも低ければ、引き続き送風ファン13を継続して作動させるが、温度センサ19の温度が第3設定温度t3以上になれば送風ファン13及びカーボンランプヒータ5の通電を停止させ(ステップS9)、エラー表示する(ステップS10)。なお、エラー表示としては、図示しない制御部に配設したブザーを鳴らす、あるいは図示しないリモコンなどの操作部にエラー表示させるなどの報知手段を備えて使用者に報知する。   In the control during the heating operation by radiant heat, when the heating operation starts, the carbon lamp heater 5 is turned on (energized) (step S1). Next, while there is no instruction to stop the heating operation (step S2), if the temperature detected by the temperature sensor 19 is lower than the set temperature t1 (for example, 60 degrees), the energization of the carbon lamp heater 5 is continued. When the temperature is equal to or higher than the set temperature t1, the blower fan 13 is operated by a command from a control unit (not shown) (step S4). And while there is no instruction | indication of heating operation stop (step S5), it is judged whether the temperature of the temperature sensor 19 became below 2nd setting temperature t2 (for example, 55 degree | times) lower than the setting temperature t1 by predetermined temperature (for example). Step S6). If the temperature falls below the second set temperature t2, the blower fan 13 is stopped (step S7). If the temperature is higher than the second set temperature t2, the temperature of the temperature sensor 19 is now higher than the set temperature t1 by a third set temperature. It is determined whether it is t3 or more (for example, 80 degrees) (step S8). If the temperature of the temperature sensor 19 is lower than the third set temperature t3, the blower fan 13 is continuously operated. If the temperature of the temperature sensor 19 becomes equal to or higher than the third set temperature t3, the blower fan 13 and the carbon lamp heater. 5 is stopped (step S9) and an error is displayed (step S10). In addition, as an error display, a notification is provided to the user by providing notification means such as sounding a buzzer arranged in a control unit (not shown) or displaying an error on an operation unit such as a remote control (not shown).

なお、ステップS2またはステップS5で運転停止指示があった場合には、カーボンランプヒータ5への通電を停止し(ステップS11)、送風ファン13が停止して(ステップS12)、暖房運転が完了する。   In addition, when there exists a driving | operation stop instruction | indication in step S2 or step S5, electricity supply to the carbon lamp heater 5 is stopped (step S11), the ventilation fan 13 stops (step S12), and heating operation is completed. .

ここで、本発明の浴室暖房機1においては上述した暖房運転の他にカーボンランプヒータ5には通電せず、送風ファン13の作動による送風運転を備えている。この送風運転には、送風ファン13の回転数を比較的上げて風量の大きい強モードとこの強モードに比べ送風ファン13の回転数を下げ風量の小さい弱モードの2つのモードを設けている。ステップS4で作動させる送風ファン13の回転数は送風運転の弱モード時の回転数であり、極力作動音を小さくし、また、風が身体に当たることによる肌寒さも緩和することができる   Here, in the bathroom heater 1 of the present invention, in addition to the heating operation described above, the carbon lamp heater 5 is not energized and is provided with a blowing operation by the operation of the blowing fan 13. In this air blowing operation, two modes are provided: a strong mode in which the rotational speed of the blower fan 13 is relatively increased to increase the air volume, and a weak mode in which the rotational speed of the air fan 13 is decreased and the air volume is lower than that in the strong mode.

図4は、別の実施形態を示す本発明の浴室暖房機を浴室に設置した実施例2を示す図である。なお、図1と同じ符号を付しているものは説明を省略する。   FIG. 4: is a figure which shows Example 2 which installed the bathroom heater of this invention which shows another embodiment in the bathroom. In addition, what attaches | subjects the code | symbol same as FIG. 1 abbreviate | omits description.

実施例2は実施例1と相違して、浴室暖房機1の側面に浴室内の空気を吸い込むための吸込口21が設けられている。   The second embodiment is different from the first embodiment in that a suction port 21 for sucking air in the bathroom is provided on the side surface of the bathroom heater 1.

なお、図4の構成においても実施例1を示す図1、2、3で説明した同様の動作を行う。すなわち、内部に備えた温度センサが図3で説明した設定温度t1よりも高い場合には送風ファンが作動し、吸込口21から吸い込まれた空気は反射板7の裏面を通って送風ファン13に吸い込まれ、吹出口9から浴室内へ吹出される。   In the configuration of FIG. 4 as well, the same operation described in FIGS. That is, when the temperature sensor provided inside is higher than the set temperature t1 described with reference to FIG. 3, the blower fan operates, and the air sucked from the suction port 21 passes through the back surface of the reflector 7 to the blower fan 13. It is sucked in and blown out from the air outlet 9 into the bathroom.

従って、実施例1同様、必要な場合のみ送風ファンを作動することにより送風ファンが作動する時間を極力なくすことができ、省エネルギー化が図られる。また、暖房運転時に送風ファンを回転させて入浴者が感じる作動音の不快な思いを緩和することができる。また、送風ファン作動時には浴室暖房機1内部が冷却されるため、カーボンランプヒータから発生する熱による反射板や暖房機内部を構成している樹脂が熱変形を起こすことを防止することができる。更に、冷却用の風も入浴者の身体に当たることによる肌寒さも緩和することができる。   Therefore, as in the first embodiment, by operating the blower fan only when necessary, the time for which the blower fan is operated can be eliminated as much as possible, thereby saving energy. Moreover, the unpleasant feeling of the operation sound which a bather feels by rotating a ventilation fan at the time of heating operation can be relieved. In addition, since the interior of the bathroom heater 1 is cooled when the blower fan is activated, it is possible to prevent the reflector and the resin constituting the interior of the heater from being thermally deformed due to heat generated from the carbon lamp heater. Furthermore, the chill caused by the cooling air hitting the bather's body can be alleviated.

図5は、更に別の実施形態を示す本発明の浴室暖房機を浴室に設置した実施例3を示す図である。   FIG. 5: is a figure which shows Example 3 which installed the bathroom heater of this invention which shows another embodiment in the bathroom.

浴室暖房機1前面のカーボンランプヒータ5及び反射板7の上部には、浴室内の空気を吸い込むための吸込口25が開口され、また吸込口25から吸込んだ空気を再び浴室に吹出すために、カーボンランプヒータ5及び反射板7近傍の上部には吹出口23a、下部には吹出口23bが略長方形で開口され、反射板7の長手方向に一列にそれぞれ複数個配設されている点で実施例1と異なる。   In the upper part of the carbon lamp heater 5 and the reflector 7 on the front surface of the bathroom heater 1, an inlet 25 for sucking in the air in the bathroom is opened, and the air sucked from the inlet 25 is again blown out into the bathroom. In the upper part of the vicinity of the carbon lamp heater 5 and the reflecting plate 7, the air outlet 23 a is opened in a substantially rectangular shape, and in the lower part, a plurality of air outlets 23 b are arranged in a row in the longitudinal direction of the reflecting plate 7. Different from the first embodiment.

図6は、本発明の実施例3に係る浴室暖房機の断面図である。   FIG. 6 is a cross-sectional view of a bathroom heater according to Embodiment 3 of the present invention.

浴室暖房機1内部には、吸込口25から浴室内の空気を吸い込み、吹出口23a、23bから再び浴室内に吹出すためのモータ15の駆動により作動する送風ファン13を実施例1同様に備えている。送風ファン13は反射板7の背面側上方に配設され、浴室暖房機1内部は、送風ファン13とカーボンランプヒータ5及び反射板7とを配置した部分と、吸込通風路25a部分とに送風ファン13の吸気口を連通させて2つに区画されており、区画により送風ファン13と吹出口23a、23bとを結ぶ空気の通路として排気通風路25bが形成されている。   The bathroom heater 1 includes a fan 13 that operates by driving a motor 15 for sucking air in the bathroom from the suction port 25 and blowing the air into the bathroom again from the air outlets 23a and 23b. ing. The blower fan 13 is disposed on the upper side of the back side of the reflector 7, and the interior of the bathroom heater 1 is blown to a portion where the blower fan 13, the carbon lamp heater 5 and the reflector 7 are arranged, and a suction ventilation passage 25 a portion. The intake port of the fan 13 is communicated and divided into two, and an exhaust ventilation passage 25b is formed as an air passage connecting the blower fan 13 and the outlets 23a and 23b by the division.

さらには反射板7の後方背面には温度検出手段としての温度センサ19を備え、カーボンランプヒータ5及び前述した送風ファン13の作動は図示しない制御部によってコントロールされる。   Further, a temperature sensor 19 as a temperature detecting means is provided on the rear rear surface of the reflecting plate 7, and the operation of the carbon lamp heater 5 and the above-described blower fan 13 is controlled by a control unit (not shown).

この構成において、図示せぬスイッチにより暖房運転時が指示されたとき、実施例1同様、制御部でカーボンランプヒータ5に通電が開始され、温度センサ19の検出温度が予め定めた所定温度より高い温度を検出した場合、送風ファン13を作動させることにより吸込口25から浴室内の空気を吸い込むが、このとき、吸込口25から吸い込まれた空気は送風ファン13から吹出され、反射板7の上部を通って吹出口23aから吹出される流路と反射板7の裏面を通って吹出口23bから吹出される流路に分かれる(図中矢印)。   In this configuration, when a heating operation is instructed by a switch (not shown), the controller starts energizing the carbon lamp heater 5 as in the first embodiment, and the temperature detected by the temperature sensor 19 is higher than a predetermined temperature. When the temperature is detected, the air in the bathroom is sucked from the suction port 25 by operating the blower fan 13. At this time, the air sucked from the suction port 25 is blown out from the blower fan 13, and the upper part of the reflector 7. It is divided into a flow path that blows out from the blower outlet 23a and a flow path that blows out from the blower outlet 23b through the back surface of the reflector 7 (arrows in the figure).

このとき、吸込口25から送風ファン13で吸い込んだ空気を反射板7裏面を通過させることで、カーボンランプヒータ5の作動で発生した反射板7裏面の浴室暖房機1内部に滞留する熱が送風機13へ流出されることで反射板7裏面に滞留する熱を取り除き、浴室暖房機1内部を冷却すると共に、吸い込まれだ空気を暖め吹出口23a及び23bから温風として吹出すようになっている。   At this time, the air sucked by the blower fan 13 from the suction port 25 is allowed to pass through the back surface of the reflector plate 7, so that the heat accumulated in the bathroom heater 1 on the back surface of the reflector plate 7 generated by the operation of the carbon lamp heater 5 is blower. 13, the heat accumulated in the back surface of the reflector 7 is removed, the interior of the bathroom heater 1 is cooled, and the sucked air is warmed and blown out as hot air from the outlets 23a and 23b. .

以上の構成により、実施例1同様、必要な場合のみ送風ファンを作動することにより送風ファンが作動する時間を極力なくし、使用者に作動音の不快な思いを緩和することができ、また、送風ファン作動時には浴室暖房機1内部が冷却され、カーボンランプヒータから発生する熱による、反射板や暖房機内部を構成している樹脂が熱変形を起こすことを防止することができる。さらに冷却用の風も身体に当たることによる肌寒さも緩和することができる。   With the above configuration, as in the first embodiment, by operating the blower fan only when necessary, it is possible to minimize the time during which the blower fan is operated, and to reduce the unpleasant feeling of the operating sound for the user. When the fan is operated, the interior of the bathroom heater 1 is cooled, and it is possible to prevent thermal deformation of the reflector and the resin constituting the interior of the heater due to heat generated from the carbon lamp heater. Furthermore, the chill caused by the cooling wind hitting the body can be alleviated.

上記実施例では、設定温度を浴室暖房機の内部を構成する樹脂の熱変形起点としたが、目的に応じて適宜設定できる。
なお、本実施例においては、浴室暖房機1が浴室の壁に設置した場合について説明したが、浴室の天井に設置した場合においても同様の効果が得られる。
In the said Example, although preset temperature was made into the thermal deformation starting point of resin which comprises the inside of a bathroom heater, it can set suitably according to the objective.
In addition, in the present Example, although the case where the bathroom heater 1 was installed in the wall of the bathroom was demonstrated, the same effect is acquired also when it installs in the ceiling of a bathroom.
