　（９）運転動作
　床置き型暖房装置（10）の運転動作について図１および図２を参照しながら説明する。床置き型暖房装置（10）の運転時には、第１ヒータ（31）が通電状態となり、ファン（50）が運転状態となる。 (9) Operating Behavior The operating behavior of the floor heating system (10) will be described with reference to FIGS. 1 and 2. FIG. During operation of the floor heating device (10), the first heater (31) is energized and the fan (50) is in operation.
　第１ヒータ（31）が通電状態になると、第１ヒータ（31）から熱線が放出される。第１ヒータ（31）から発する熱線の一部は、直接的に前方へ進む。第１ヒータ（31）から発する熱線の残部は、反射板（40）で反射された後、間接的に前方へ進む。前方へ進んだ熱線は、耐熱ガラス（60）を透過する。このように、ケーシング（11）の前側へ輻射熱が放出される。耐熱ガラス（60）は、第１ヒータ（31）の熱を吸収する。 When the first heater (31) is energized, hot wire is emitted from the first heater (31). A portion of the heat rays emitted from the first heater (31) travels forward directly. The rest of the heat rays emitted from the first heater (31) indirectly travel forward after being reflected by the reflector (40). The heat rays traveling forward pass through the heat-resistant glass (60). In this way, radiant heat is released to the front side of the casing (11). The heat-resistant glass (60) absorbs heat from the first heater (31).
　ファン（50）が運転されると、室内空間（S）の室内空気は吸込口（20）に吸い込まれる。この空気は、吸込空間（22）から第１流路（23）に流入し、連通路（24）に向かって上向きに流れる。第１流路（23）の空気は、２つの第１ヒータ（31）と、該第１ヒータ（31）から吸熱した耐熱ガラス（60）とにより順次加熱される。 When the fan (50) operates, the indoor air in the indoor space (S) is sucked into the suction port (20). This air flows from the suction space (22) into the first flow path (23) and flows upward toward the communication path (24). The air in the first flow path (23) is sequentially heated by the two first heaters (31) and the heat-resistant glass (60) that absorbs heat from the first heaters (31).
　第１流路（23）で加熱された空気は、連通路（24）を介して第２流路（25）に流入する。第２流路（25）の空気は、第１ヒータ（31）から吸熱した反射板（40）によって加熱されながら下方に向かって流れる。 The air heated in the first flow path (23) flows through the communication path (24) into the second flow path (25). The air in the second flow path (25) flows downward while being heated by the reflecting plate (40) that has absorbed heat from the first heater (31).
　この空気は、反射板（40）の下端を通過した後、吹出空間（26）に流入する。吹出空間（26）の空気は、ファン（50）を通過した後、吹出口（21）から室内空間（S）に温風として吹き出される。 This air flows into the blowout space (26) after passing through the lower end of the reflector (40). After passing through the fan (50), the air in the blowout space (26) is blown out as warm air from the blowout port (21) into the indoor space (S).
　このように、本実施形態の床置き型暖房装置（10）は、吹出口（21）から温風を吹き出すことで、耐熱ガラス（60）からの輻射熱だけでなく、吹出口（21）からの温風によって室内空間（S）を暖房できる。吹出口（21）は、ケーシング（11）の下部に位置する。具体的には、吹出口（21）は床面（F）に沿った位置になる。このため、ユーザの足下に温風を吹き出すことができ、ユーザの快適性を向上できる。 In this way, the floor heating device (10) of the present embodiment blows out warm air from the air outlet (21), so that not only radiant heat from the heat-resistant glass (60) but also heat from the air outlet (21) The indoor space (S) can be heated by warm air. The blowout port (21) is located below the casing (11). Specifically, the outlet (21) is located along the floor (F). Therefore, warm air can be blown out to the user's feet, and the user's comfort can be improved.

The reflector (40) has a first curved portion (41), a second curved portion (42) and a connecting portion (43). The first curved surface portion (41) is arranged above the second curved surface portion (42). The connecting portion (43) connects the first curved surface portion (41) and the second curved surface portion (42). The first curved surface portion (41) and the second curved surface portion (42) have substantially the same shape.
　第１曲面部（41）および第２曲面部（42）は、前方から後方に向かって膨出するように形成される。第１曲面部（41）および第２曲面部（42）の、左右方向から見た縦断面の形状は円弧状である。連結部（43）は、左右方向に延びる平坦な板形状である。連結部（43）の板面は、前面（12）および後面（13）に対向する。連結部（43）は、第１曲面部（41）の下端と、第２曲面部（42）の上端とに接続する。 The first curved surface portion (41) and the second curved surface portion (42) are formed to protrude from the front to the rear. The longitudinal cross-section of the first curved surface portion (41) and the second curved surface portion (42) when viewed in the left-right direction is arcuate. The connecting portion (43) has a flat plate shape extending in the left-right direction. A plate surface of the connecting portion (43) faces the front surface (12) and the rear surface (13).

The first heater (31) is arranged in front of the bulging tops (T) of the curved portions (41, 42). The top (T) is the rear end of the curved surface (41, 42). The first heater (31) is arranged behind the front ends of the curved portions (41, 42). Specifically, the first heater (31) is arranged at the focal point of the parabola of each curved surface portion (41, 42).
　（１０－１）第１傾斜部および第２傾斜部
　各曲面部（41，42）は、第１傾斜部（R1）と第２傾斜部（R2）とを有する。第１傾斜部（R1）は、曲面部（41，42）の下側部分である。第２傾斜部（R2）は、曲面部（41，42）の上側部分である。第１傾斜部（R1）は、反射された熱線が前面（12）に向かって上向きに導かれるように、前面（12）に向かうにつれて下方に傾斜する。一方、第２傾斜部（R2）は、反射された熱線が前面（12）に向かって下向きに導かれるように、前面（12）に向かうにつれて上方に傾斜する。 (10-1) First Slanted Part and Second Slanted Part Each curved surface part (41, 42) has a first inclined part (R1) and a second inclined part (R2). The first inclined portion (R1) is the lower portion of the curved surface portions (41, 42). The second inclined portion (R2) is the upper portion of the curved surface portions (41, 42). The first slope (R1) slopes downward toward the front surface (12) so that the reflected heat rays are guided upward toward the front surface (12). On the other hand, the second slope (R2) slopes upward toward the front surface (12) so that the reflected heat rays are guided downward toward the front surface (12).
　このように、反射板（40）の各曲面部（41，42）が第１傾斜部（R1）および第２傾斜部（R2）を有することで、前面（12）の前方にいるユーザの足元だけでなく、該ユーザの胴体に向けて輻射熱を与える一方、該ユーザの顔には輻射熱が当たりにくくなる。このことで、ユーザに与える快適性が向上する。具体的に、本実施形態の床置き型暖房装置（10）の輻射範囲は、前面（12）から前方に向かって１．８ｍの位置から高さ１．１ｍまでの高さの範囲である。 In this way, each of the curved surface portions (41, 42) of the reflector (40) has the first inclined portion (R1) and the second inclined portion (R2), so that the feet of the user in front of the front surface (12) are In addition, while the radiant heat is directed toward the body of the user, the face of the user is less likely to receive the radiant heat. This improves the comfort given to the user. Specifically, the radiation range of the floor-standing heating device (10) of this embodiment is a range from a position 1.8 m forward from the front surface (12) to a height of 1.1 m.
　反射板（40）は、第１ヒータ（31）とファン（50）とを結ぶ最短経路Ｌ１を横切るように配置される。具体的に、反射板（40）のうち第２曲面部（42）の第１傾斜部（R1）が、第１ヒータ（31）とファン（50）とを結ぶ最短経路Ｌ１内に配置される。このような配置により、第２曲面部（42）に配置される第１ヒータ（31）からファン（50）に直接向かう熱線が、第２曲面部（42）の第１傾斜部（R1）により遮られる。また、このような第２曲面部（42）の配置により、第１流路（23）において第１ヒータ（31）加熱された空気が、最短経路Ｌ１で直接ファン（50）に流入しない。 The reflector (40) is arranged across the shortest path L1 connecting the first heater (31) and the fan (50). Specifically, the first inclined portion (R1) of the second curved portion (42) of the reflector (40) is arranged in the shortest path L1 connecting the first heater (31) and the fan (50). . With this arrangement, heat rays from the first heater (31) arranged on the second curved surface portion (42) directly directed toward the fan (50) are blocked. In addition, due to the arrangement of the second curved surface portion (42), the air heated by the first heater (31) in the first flow path (23) does not directly flow into the fan (50) along the shortest route L1.
　（１０－２）ガイド部
　反射板（40）は、ガイド部（42）を有する。本実施形態の第２曲面部（42）は、ガイド部（42）の一例である。第２曲面部（42）は、第２流路（25）において上方から下方に向かって流れる空気をファン（50）へ直接案内する。第２曲面部（42）は、ファン（50）よりも後面（13）側に膨出するように形成される。具体的に、第２曲面部（42）の第１傾斜部（R1）の下端の下方にファン（50）が配置される。このような配置により、第２曲面部（42）の後端は、ファン（50）よりも後方に配置される。このように第２曲面部（42）が形成されることで、第２流路（25）を下方に向かって流れる空気は、第２曲面部（42）の後方を流れる際に、第１傾斜部（R1）の裏面をつたうようにファン（50）に向かって流れる。 (10-2) Guide Portion The reflector (40) has a guide portion (42). The second curved surface portion (42) of the present embodiment is an example of the guide portion (42). The second curved surface portion (42) directly guides air flowing downward in the second flow path (25) to the fan (50). The second curved surface portion (42) is formed to protrude toward the rear surface (13) from the fan (50). Specifically, the fan (50) is arranged below the lower end of the first inclined portion (R1) of the second curved portion (42). Due to this arrangement, the rear end of the second curved surface portion (42) is arranged behind the fan (50). Since the second curved surface portion (42) is formed in this way, the air flowing downward in the second flow path (25) moves toward the first inclined surface portion (42) when flowing behind the second curved surface portion (42). It flows toward the fan (50) along the back surface of the part (R1).

　（１２）変形例
　上記実施形態については、以下のような変形例の構成としてもよい。以下では、主として上記実施形態と異なる点について述べる。 (12) Modifications The above embodiment may be modified as follows. Differences from the above embodiment will be mainly described below.
　（１２－１）変形例１
　図６に示す変形例１の床置き型暖房装置（10）では、上記実施形態の床置き側暖房装置のケーシング（11）の前側開口（11a）に相当する部分が吸込口（20）を構成する。本例の吸込口（20）には、複数の孔（H）を有する吸込部材（60）が設けられる。吸込部材（60）は、本開示のパネル（60）の一例である。吸込部材（60）は、例えば、パンチングプレートである。パンチングプレートは、平板状のＳＵＳ等の金属素材で構成される。吸込部材（60）は、ケーシング（11）の吸込口（20）を覆うようにケーシング（11）の前面（12）に設けられる。吸込部材（60）は、吸込口（20）の上端から下端に亘って上下方向に延びる。吸込部材（60）は、吸込口（20）の左端から右端に亘って左右方向に延びる。複数の孔（H）は、吸込部材（60）の略全面に形成される。そのため、吸込口（20）の略全面から室内空間（S）の空気を吸い込むことができる。本例のパネル（60）は、メッシュ部材であってもよい。 (12-1) Modification 1
In the floor-standing heating device (10) of Modified Example 1 shown in FIG. 6, the portion corresponding to the front opening (11a) of the casing (11) of the floor-standing heating device of the above embodiment constitutes the suction port (20). do. The suction port (20) of this example is provided with a suction member (60) having a plurality of holes (H). The suction member (60) is an example of the panel (60) of the present disclosure. The suction member (60) is, for example, a punching plate. The punching plate is made of a flat metal material such as SUS. The suction member (60) is provided on the front surface (12) of the casing (11) so as to cover the suction port (20) of the casing (11). The suction member (60) extends vertically from the upper end to the lower end of the suction port (20). The suction member (60) extends in the left-right direction from the left end to the right end of the suction port (20). A plurality of holes (H) are formed substantially over the entire surface of the suction member (60). Therefore, the air in the indoor space (S) can be sucked through substantially the entire surface of the suction port (20). The panel (60) of this example may be a mesh member.
　床置き型暖房装置（10）の運転時には、上記実施形態と同様、第１ヒータ（31）の熱線の一部は前方に進み、残部は反射板（40）に反射し、最終的にケーシング（11）の前方へ進む。 During operation of the floor heating device (10), as in the above embodiment, part of the heat ray of the first heater (31) travels forward, the rest of the heat ray is reflected by the reflector (40), and finally reaches the casing ( 11) Go forward.
　室内空間（S）の空気は、吸込部材（60）の略全面を介して吸い込まれる。このように本例の吸込口（20）の開口面積を大きくできるため、吸い込み風量を増大できる。本例の空気通路（P）は、吸込空間（22）を有さない。吸込口（20）からの空気は、第１流路（23）に直接流入する。第１流路（23）において第１ヒータ（31）により加熱された空気は、連通路（24）を介して第２流路（25）に流入する。第２流路（25）の空気は、第１ヒータ（31）により加熱された反射板（40）により加熱されながら下方に向かって流れる。この空気は、反射板（40）の下端を通過した後、吹出空間（26）に流入して、ファン（50）を通過する。ファン（50）を通過した空気は、吹出口（21）から温風として室内空間（S）に吹き出される。 The air in the indoor space (S) is sucked through substantially the entire surface of the suction member (60).

The air heated by the first heater (31) in the first flow path (23) flows through the communication path (24) into the second flow path (25). The air in the second flow path (25) flows downward while being heated by the reflector (40) heated by the first heater (31). After passing through the lower end of the reflector (40), this air flows into the blowing space (26) and passes through the fan (50). The air that has passed through the fan (50) is blown out from the outlet (21) into the indoor space (S) as warm air.

A lower end of the heat-resistant glass (61) is fixed to the support plate (39). The upper end of the heat-resistant glass (61) is arranged below the upper surface (14). In other words, a gap is formed between the upper end of the heat-resistant glass (61) and the upper surface (14). The heat-resistant glass (61) faces the suction member (60). Specifically, the entire area of the heat-resistant glass (61) is arranged so as to overlap the suction member (60) in the front-rear direction.
　変形例２の第１流路（23）は、吸込部材（60）と耐熱ガラス（61）との間に形成される。具体的に、第１流路（23）は、吸込部材（60）の前面と耐熱ガラス（61）の後面との間に形成される。耐熱ガラス（61）と反射板（40）との間には、第１ヒータ（31）が配置される空間が形成される。この空間は、実質的には空気が流れない空間である。 The first flow path (23) of Modification 2 is formed between the suction member (60) and the heat-resistant glass (61). Specifically, the first flow path (23) is formed between the front surface of the suction member (60) and the rear surface of the heat-resistant glass (61). A space in which the first heater (31) is arranged is formed between the heat-resistant glass (61) and the reflector (40). This space is a space in which air does not substantially flow.
　床置き型暖房装置（10）の運転時には、上記実施形態と同様、第１ヒータ（31）の熱線の一部は前方に進み、残部は反射板（40）に反射して前方に進む。前方に進む熱線のほぼ全てが、耐熱ガラス（61）を透過して吸込部材（60）に向かい、最終的にケーシング（11）の前方へ進む。 During operation of the floor heating device (10), part of the heat ray of the first heater (31) travels forward, and the rest of the heat ray travels forward after being reflected by the reflector (40), as in the above embodiment. Almost all of the heat rays traveling forward pass through the heat-resistant glass (61), head toward the suction member (60), and finally travel forward through the casing (11).
　吸込口（20）から吸い込まれた室内空間（S）の空気は、第１流路（23）において加熱される。具体的に、第１流路（23）の空気は、第１ヒータ（31）から吸熱した耐熱ガラスにより加熱される。第１流路（23）の空気は、連通路（24）を介して第２流路（25）に流入する。第２流路（25）の空気は、第１ヒータ（31）から吸熱した反射板（40）により加熱されながら下方に向かって流れる。反射板（40）を通過した空気は、吹出空間（26）に流入して、ファン（50）を通過する。ファン（50）を通過した空気は、吹出口（21）から温風として室内空間（S）に吹き出される。 The air in the indoor space (S) sucked from the suction port (20) is heated in the first flow path (23). Specifically, the air in the first flow path (23) is heated by heat-resistant glass that has absorbed heat from the first heater (31). Air in the first flow path (23) flows into the second flow path (25) through the communication path (24). The air in the second flow path (25) flows downward while being heated by the reflecting plate (40) that has absorbed heat from the first heater (31). After passing through the reflector (40), the air flows into the blowout space (26) and passes through the fan (50). The air that has passed through the fan (50) is blown out from the outlet (21) into the indoor space (S) as warm air.
　本例の床置き型暖房装置（10）では、耐熱ガラス（61）が第１ヒータ（31）から吸収した熱を空気通路（P）の空気の加熱に利用できる。加えて、耐熱ガラス（61）が第１ヒータ（31）から吸熱するため、耐熱ガラス（61）の前方に配置される吸込部材（60）が過剰に加熱されることを抑制できる。その結果、ユーザに対する安全性を確保できる。 In the floor heating device (10) of this example, the heat absorbed by the heat-resistant glass (61) from the first heater (31) can be used to heat the air in the air passage (P). In addition, since the heat-resistant glass (61) absorbs heat from the first heater (31), excessive heating of the suction member (60) arranged in front of the heat-resistant glass (61) can be suppressed. As a result, safety for users can be ensured.

Almost all of the heat rays traveling forward travel through the rear suction member (61) to the front suction member (60) and finally to the front of the casing (11). The rear suction member (61) absorbs part of the heat of the first heater (31).
　第１流路（23）では、前側吸込部材（60）を介して第１流路（23）に吸い込まれた空気の一部は、後側吸込部材（61）の複数の孔（H）を通過する。第１流路（23）の空気は、第１ヒータ（31）と、第１ヒータ（31）の熱を吸収した後側吸込部材（61）とにより加熱される。この空気は、連通路（24）を介して、第２流路（25）に流入する。第２流路（25）の空気は、第１ヒータ（31）から吸熱した反射板（40）により加熱されながら下方に流れる。反射板（40）の下端を通過した空気は、吹出空間（26）の下部のファン（50）を通過して、吹出口（21）から室内空間（S）に吹き出される。 In the first flow path (23), part of the air sucked into the first flow path (23) through the front suction member (60) passes through the plurality of holes (H) of the rear suction member (61). pass.

　本例においても、後側吸込部材（61）が第１ヒータ（31）の熱を吸収することで、前側吸込部材（60）が過剰に加熱されることを抑制できる。 Also in this example, the rear suction member (61) absorbs the heat of the first heater (31), thereby suppressing excessive heating of the front suction member (60).

A floor-standing heating device (10) of Modification 4 shown in FIG. 9 is provided with a rear heat-resistant glass (61) in addition to the floor-standing heating device (10) of the above embodiment.
　変形例４の床置き型暖房装置（10）は、パネル（60）として前側耐熱ガラス（60）が設けられる。前側耐熱ガラス（60）は、上記実施形態の耐熱ガラス（60）である。具体的に、前側耐熱ガラス（60）は、ケーシング（11）の前側開口（11a）に設けられる。前側耐熱ガラス（60）は、ケーシング（11）の前面（12）に沿って形成される。具体的には、前側耐熱ガラス（60）は、ケーシング（11）の上端から吸込口（20）に亘って上下に延びている。前側耐熱ガラス（60）は、ケーシング（11）の左面（17）から右面（16）に亘って左右に延びている。 The floor-standing heating device (10) of Modification 4 is provided with a front heat-resistant glass (60) as a panel (60). The front heat-resistant glass (60) is the heat-resistant glass (60) of the above embodiment. Specifically, the front heat-resistant glass (60) is provided in the front opening (11a) of the casing (11). A front heat resistant glass (60) is formed along the front surface (12) of the casing (11). Specifically, the front heat-resistant glass (60) extends vertically from the upper end of the casing (11) to the suction port (20). The front heat-resistant glass (60) extends laterally from the left surface (17) to the right surface (16) of the casing (11).
　後側耐熱ガラス（61）は、前側耐熱ガラス（60）と同様に、平板状に形成された耐熱性に優れたガラス材料で構成される。後側耐熱ガラス（61）は、第１ヒータ（31）および反射板（40）から発する遠赤外線を透過する特性を有する。後側耐熱ガラス（61）は、第１ヒータ（31）および反射板（40）から発する熱を吸収する特性を有する。 Like the front heat-resistant glass (60), the rear heat-resistant glass (61) is made of a flat glass material with excellent heat resistance. The rear heat-resistant glass (61) has a property of transmitting far infrared rays emitted from the first heater (31) and the reflector (40). The rear heat-resistant glass (61) has the property of absorbing heat generated from the first heater (31) and the reflector (40).
　後側耐熱ガラス（61）は、ケーシング（11）の前面（12）よりも後方、かつ、第１ヒータ（31）よりも前方に配置される。後側耐熱ガラス（61）は、前側耐熱ガラス（60）と平行な状態で支持部材（図示省略）を介してケーシング（11）に固定される。後側耐熱ガラス（61）は、前側耐熱ガラス（60）と対向する。後側耐熱ガラス（61）の下端の高さ位置は、前側耐熱ガラス（60）の下端の高さ位置と概ね等しい。後側耐熱ガラス（61）の上端の高さ位置は、後側耐熱ガラス（61）の上端の高さ位置よりも低い。後側耐熱ガラス（61）の全域が、前後方向において、前側耐熱ガラス（60）と重なる。 The rear heat-resistant glass (61) is arranged rearward of the front surface (12) of the casing (11) and forward of the first heater (31). The rear heat-resistant glass (61) is fixed to the casing (11) in parallel with the front heat-resistant glass (60) via a support member (not shown). The rear heat-resistant glass (61) faces the front heat-resistant glass (60). The height position of the lower end of the rear heat-resistant glass (61) is substantially equal to the height position of the lower end of the front heat-resistant glass (60). The height position of the upper end of the rear heat-resistant glass (61) is lower than the height position of the upper end of the rear heat-resistant glass (61). The entire area of the rear heat-resistant glass (61) overlaps the front heat-resistant glass (60) in the front-rear direction.
　変形例４の反射板（40）は、前側反射板（40a）および後側反射板（40b）を有する。前側反射板（40a）は、上記実施形態の反射板（40）と同じ構成である。変形例４においても、反射板（40）は、第１ヒータ（31）とファン（50）とを結ぶ最短経路Ｌ１を横切るように配置される。具体的に、前側反射板（40a）の第２曲面部（42）の第１傾斜部（R1）が、第１ヒータ（31）とファン（50）とを結ぶ最短経路Ｌ１上に介在する。 The reflector (40) of Modification 4 has a front reflector (40a) and a rear reflector (40b). The front reflector (40a) has the same configuration as the reflector (40) of the above embodiment. Also in Modification 4, the reflector (40) is arranged to cross the shortest path L1 connecting the first heater (31) and the fan (50). Specifically, the first inclined portion (R1) of the second curved portion (42) of the front reflector (40a) is on the shortest path L1 connecting the first heater (31) and the fan (50).
　後側反射板（40b）は、第１ヒータ（31）および前側反射板（40a）の後方に配置される。後側反射板（40b）の上端は、第１支持板（35）を介してケーシング（11）に固定される。後側反射板（40b）の下端は、第２支持板（36）を介してケーシング（11）に固定される。 The rear reflector (40b) is arranged behind the first heater (31) and the front reflector (40a). The upper end of the rear reflector (40b) is fixed to the casing (11) via the first support plate (35). A lower end of the rear reflector (40b) is fixed to the casing (11) via the second support plate (36).
　後側反射板（40b）は、図８の紙面方向（左右方向）に直角な断面視において、略円弧状の第３曲面部（44）を含む。第３曲面部（44）は、左右方向に延びるとともに、該左右方向において略同一の断面形状を有する。具体的には、第３曲面部（44）は、後方に膨出した曲面状に形成される。第３曲面部（44）の前面には、第１ヒータ（31）の熱線を前方に反射する第３傾斜部（R3）が形成される。後側反射板（40b）により、反射板（40）と後面（13）との間の空間には空気が流れない。 The rear reflector (40b) includes a substantially arcuate third curved surface portion (44) in a cross-sectional view perpendicular to the paper surface direction (horizontal direction) of FIG. The third curved surface portion (44) extends in the left-right direction and has substantially the same cross-sectional shape in the left-right direction. Specifically, the third curved surface portion (44) is formed into a curved surface that bulges rearward. A third inclined portion (R3) is formed on the front surface of the third curved portion (44) to reflect forward the heat rays of the first heater (31). Air does not flow in the space between the reflector (40) and the rear surface (13) due to the rear reflector (40b).
　変形例４の第１流路（23）は、後側耐熱ガラス（61）と前側耐熱ガラス（60）との間に形成される。第１流路（23）は、空気が上方に流れる流路を構成している。変形例４の連通路（24）は、前側耐熱ガラス（60）と上面（14）との間に形成される。連通路（24）では、上方を向く空気流れがＵターンして下方を向く空気流れとなる。変形例４の第２流路（25）は、前側反射板（40a）と、後側耐熱ガラス（61）との間に形成される。第２流路（25）は、空気が下方に流れる流路を構成している。変形例４の吹出空間（26）は、吹出口（21）の奥側（後側）に形成される。吹出空間（26）には、ファン（50）が配置される。 The first flow path (23) of Modification 4 is formed between the rear heat-resistant glass (61) and the front heat-resistant glass (60). The first flow path (23) constitutes a flow path through which air flows upward. The communication path (24) of Modification 4 is formed between the front heat-resistant glass (60) and the upper surface (14). In the communication passage (24), the upward airflow makes a U-turn and becomes a downward airflow. The second flow path (25) of Modification 4 is formed between the front reflector (40a) and the rear heat-resistant glass (61). The second flow path (25) constitutes a flow path through which air flows downward. The blowout space (26) of Modification 4 is formed on the far side (rear side) of the blowout port (21). A fan (50) is arranged in the blowing space (26).
　上記実施形態と同様に、第１ヒータ（31）が通電状態になると、第１ヒータ（31）から熱線が放出される。第１ヒータ（31）から発する熱線の一部は、直接的に前方へ移動する。第１ヒータ（31）から発する熱線の残部は、前側反射板（40a）および後側反射板（40b）で反射された後、間接的に前方へ移動する。これにより、ケーシング（11）の前側へ輻射熱が放出される。 As in the above embodiment, when the first heater (31) is energized, hot wire is emitted from the first heater (31). Some of the heat rays emitted from the first heater (31) directly move forward. The rest of the heat rays emitted from the first heater (31) indirectly travel forward after being reflected by the front reflector (40a) and the rear reflector (40b). As a result, radiant heat is released to the front side of the casing (11).
　第１ヒータ（31）から放出された熱が後側耐熱ガラス（61）を透過すると、この熱が後側耐熱ガラス（61）に吸収される。次いで、後側耐熱ガラス（61）を透過した熱が前側耐熱ガラス（60）を透過すると、この熱が前側耐熱ガラス（60）に吸収される。このように、第１ヒータ（31）の前側に後側耐熱ガラス（61）および前側耐熱ガラス（60）を設けることで、ケーシング（11）の前側の温度が過剰に高くなることを抑制できる。 When the heat emitted from the first heater (31) passes through the rear heat-resistant glass (61), the heat is absorbed by the rear heat-resistant glass (61). Next, when the heat transmitted through the rear heat-resistant glass (61) is transmitted through the front heat-resistant glass (60), the heat is absorbed by the front heat-resistant glass (60). By thus providing the rear heat-resistant glass (61) and the front heat-resistant glass (60) in front of the first heater (31), it is possible to prevent the temperature of the front side of the casing (11) from becoming excessively high.
　ファン（50）が運転されると、室内空間（S）の室内空気が吸込口（20）に吸い込まれる。この空気は、第１流路（23）を上方に流れる。第１流路（23）の空気は、前側耐熱ガラス（60）および後側耐熱ガラス（61）の熱が付与されることで加熱される。連通路（24）を介して、第２流路（25）に流入した空気は、第２流路（25）の下方に向かって流れる過程で、第１ヒータ（31）により加熱される。加熱された空気は、ファン（50）を通過して、吹出口（21）から温風として室内空間（S）に吹き出される。 When the fan (50) operates, the indoor air in the indoor space (S) is drawn into the suction port (20). This air flows upward through the first flow path (23). The air in the first flow path (23) is heated by the heat of the front heat-resistant glass (60) and the rear heat-resistant glass (61). The air that has flowed into the second flow path (25) through the communication path (24) is heated by the first heater (31) while flowing downward in the second flow path (25). The heated air passes through the fan (50) and is blown out from the outlet (21) into the indoor space (S) as warm air.
　このように本例では、第１流路（23）において後側耐熱ガラス（61）の前面および前側耐熱ガラス（60）の後面に沿って空気が流れることで、後側耐熱ガラス（61）および前側耐熱ガラス（60）で吸熱した熱を、空気の加熱に利用できる。同時に、後側耐熱ガラス（61）および後側耐熱ガラス（61）を空気によって冷却できるので、ケーシング（11）の前側の温度が過剰に高くなることを抑制できる。 In this way, in the present example, air flows along the front surface of the rear heat-resistant glass (61) and the rear surface of the front heat-resistant glass (60) in the first flow path (23). The heat absorbed by the front heat-resistant glass (60) can be used to heat the air. At the same time, since the rear heat-resistant glass (61) and the rear heat-resistant glass (61) can be cooled by air, it is possible to prevent the temperature of the front side of the casing (11) from becoming excessively high.
　特に、前側耐熱ガラス（60）は、ケーシング（11）の外部に露出しているため、前側耐熱ガラス（60）の表面温度が高くなり過ぎると、ユーザの安全性が損なわれてしまう。これに対し、本実施形態では、前側耐熱ガラス（60）の表面温度を下げることができるので、ユーザの安全性を確保できる。 In particular, since the front heat-resistant glass (60) is exposed to the outside of the casing (11), if the surface temperature of the front heat-resistant glass (60) becomes too high, the user's safety is compromised. In contrast, in the present embodiment, the surface temperature of the front heat-resistant glass (60) can be lowered, thereby ensuring the safety of the user.
　（１２－５）変形例５
　図１０に示す変形例５の床置き型暖房装置（10）では、ファン（50）の位置が上記変形例１と異なる。ファン（50）は、空気通路（P）において、２つの第１ヒータ（31）のうち上側に配置される第１ヒータ（31）よりも上方に配置される。ファン（50）は、第２流路（25）の上流端またその近傍に配置される。本例においても、反射板（40）は、第１ヒータ（31）とファン（50）とを結ぶ最短経路を横切るように配置される。 (12-5) Modification 5
In the floor heating apparatus (10) of Modification 5 shown in FIG. 10, the position of the fan (50) is different from that in Modification 1 above. The fan (50) is disposed above the first heater (31) of the two first heaters (31) in the air passage (P). The fan (50) is arranged at or near the upstream end of the second flow path (25). Also in this example, the reflector (40) is arranged to cross the shortest path connecting the first heater (31) and the fan (50).
　　本例の床置き型暖房装置（10）は、第２ヒータ（33）を備える。第２ヒータ（33）は、例えば通電状態されることで発熱する電気ヒータである。第２ヒータ（33）は、サーミスタやペルチェ素子などの熱電素子を有する。第２ヒータ（33）は、第２流路（25）の下端に配置される。具体的に、第２ヒータ（33）は、２つの第１ヒータ（31）のうち下側に配置される第１ヒータ（31）よりも下方に配置される。 The floor heating device (10) of this example includes a second heater (33). The second heater (33) is, for example, an electric heater that generates heat when energized. The second heater (33) has a thermoelectric element such as a thermistor or Peltier element. The second heater (33) is arranged at the lower end of the second flow path (25). Specifically, the second heater (33) is arranged below the first heater (31) of the two first heaters (31) arranged on the lower side.
　　第２ヒータ（33）は、空気通路（P）の空気を加熱する。具体的に、第２ヒータ（33）は、第２流路（25）の空気を加熱する。本例の床置き型暖房装置（10）では、ファン（50）はケーシング（11）の上端付近に配置されるのに対し、第２ヒータ（33）はケーシング（11）の下端付近に配置される。このように、ファン（50）は、第２ヒータ（33）から比較的離れた位置に設けられるため、第２ヒータ（33）の発熱によるファン（50）への影響が抑制される。 The second heater (33) heats the air in the air passage (P). Specifically, the second heater (33) heats the air in the second flow path (25). In the floor heating device (10) of this example, the fan (50) is arranged near the upper end of the casing (11), whereas the second heater (33) is arranged near the lower end of the casing (11). be. In this way, the fan (50) is provided at a position relatively distant from the second heater (33), thereby suppressing the influence of the heat generated by the second heater (33) on the fan (50).
　　本例の床置き型暖房装置（10）では、第１ヒータ（31）、第２ヒータ（33）及びファン（50）を運転させることで、第１ヒータ（31）から吸熱した反射板（40）により加熱されながら下方に向かって流れる。反射板（40）の後面の下端を通過した空気は、第２ヒータ（33）を通過することでさらに加熱される。このように、第１ヒータ（31）のみの加熱では不足する吹出口（21）の温風温度を第２ヒータ（33）により加熱することで補うことができる。さらに、第２ヒータ（33）及びファン（50）を運転させることで、吹出口（21）から温風のみを吹き出す運転を実行できる。 In the floor-standing heating device (10) of this example, the first heater (31), the second heater (33) and the fan (50) are operated so that the reflector (40) absorbs heat from the first heater (31). ) flows downward while being heated by The air that has passed through the lower end of the rear surface of the reflector (40) is further heated by passing through the second heater (33). In this way, the second heater (33) can compensate for the insufficient hot air temperature of the outlet (21) by heating with the first heater (31) alone. Furthermore, by operating the second heater (33) and the fan (50), it is possible to carry out an operation in which only warm air is blown out from the outlet (21).

As a result, the area in front of the front surface (12) can be heated intensively.
