Description

本発明は、浴室暖房機、特に、浴室の天井に埋設して使用される浴室暖房機に関する。 The present invention relates to a bathroom heater, and more particularly to a bathroom heater used by being embedded in a ceiling of a bathroom.

従来、ファンや熱交換器を収容する下面開放箱状の本体ケースと、本体ケース下面のケース開口部を浴室側から覆うカバーとを備え、本体ケースを天井裏の空間に吊り下げた状態で取り付け、ケース開口部外周のフランジとカバーとで浴室の天井壁を上下から挟み付けるようにして設置される浴室暖房機が知られている。ところが、このようにして設置される浴室暖房機の場合、天井壁の厚みが基準より大きいと、本体ケースの内部に設けられた送風路の下流端とカバーの吹出口周縁との間に不要な隙間が形成されてしまい、上記隙間からの空気漏れによって暖房や乾燥など運転性能が低下する虞があった。 Conventionally, it has a box-shaped main body case that houses the fan and heat exchanger, and a cover that covers the case opening on the lower surface of the main body case from the bathroom side, and is mounted with the main body case suspended in the space behind the ceiling There is known a bathroom heater that is installed such that a ceiling wall of a bathroom is sandwiched from above and below by a flange and a cover at the outer periphery of the case opening. However, in the case of the bathroom heater installed in this way, if the thickness of the ceiling wall is larger than the reference, it is unnecessary between the downstream end of the air passage provided inside the main body case and the peripheral edge of the outlet of the cover. A gap is formed, and there is a possibility that the operation performance such as heating and drying is deteriorated due to air leakage from the gap.

そこで、この種の浴室暖房機において、送風路が、ファンの空気送出部からケース開口部へ向かって延設される本体筒部と、本体筒部のケース開口部側の端部に上下移動可能な状態で設けられる可動筒部とで構成され、さらに本体筒部と可動筒部との側壁相互をバネ部材で連結することで、送風路の下流端開口の位置を上下自在に調整できるようにしたものが提案されている（例えば、特許文献１および２参照）。 Therefore, in this type of bathroom heater, the air passage can be moved up and down to the main body cylinder extending from the fan air delivery part toward the case opening and the end of the main body cylinder on the case opening side. In addition, the position of the downstream end opening of the air passage can be adjusted up and down by connecting the side walls of the main body cylinder portion and the movable cylinder portion with a spring member. Have been proposed (see, for example, Patent Documents 1 and 2).

このものでは、天井壁の厚みが異なっても、送風路の下流端（可動筒部の下端）を吹出口の周縁上部に当接させた状態で設置することができるから、上記空気漏れによる運転性能の低下が生じ難い。 In this case, even if the thickness of the ceiling wall is different, it can be installed with the downstream end of the air passage (the lower end of the movable cylinder part) in contact with the upper peripheral edge of the air outlet. It is difficult for performance to decrease.

しかしながら、上記従来の浴室暖房機のように、本体筒部と可動筒部とをバネ部材で連結したものでは、バネ部材の長さや弾性力の差異によって、可動筒部が本体ケースに対して傾いて保持されたり、本体ケース内の上方に位置し過ぎたりして、設置作業に手間がかかる場合がある。 However, in the case where the main body cylinder part and the movable cylinder part are connected by a spring member as in the above-described conventional bathroom heater, the movable cylinder part is inclined with respect to the main body case due to the difference in length and elastic force of the spring member. May be held up or positioned too much in the main body case, and installation work may take time.

また、本体ケースの左右幅は、天井の取付口の寸法に制限があるため一定以上大きく設定できない。一方で、暖房運転や乾燥運転時の空気の循環効率を考慮すれば、送風路の左右幅は、温風が浴室内に効率良く行き渡るようできる限り大きく設定するのが望ましい。しかしながら、上記従来の浴室暖房機のように、送風路の本体筒部と可動筒部との側壁相互をバネ部材で連結したものでは、本体ケースと送風路との対向する側壁相互間に、バネ部材を配設するための空間を確保する必要があるため、その分、送風路の左右幅を小さく設定せざるを得なかった。 Further, the left and right widths of the main body case cannot be set larger than a certain value because there are limitations on the dimensions of the ceiling mounting openings. On the other hand, considering the air circulation efficiency during the heating operation and the drying operation, it is desirable to set the left and right width of the air passage as large as possible so that the hot air can be efficiently distributed in the bathroom. However, in the case where the side wall of the main body cylinder part and the movable cylinder part of the air passage is connected by a spring member as in the conventional bathroom heater, a spring is provided between the opposing side walls of the main body case and the air passage. Since it is necessary to secure a space for disposing the members, the left and right widths of the air passages have to be set small accordingly.

本発明は、上記課題を鑑みてなされたものであり、その目的は、送風路の下流端開口の位置を上下に調整可能な浴室暖房機において、設置性に優れ、且つ、浴室内に効率良く温風を送出可能な運転性能の高い浴室暖房機を提供することにある。 The present invention has been made in view of the above problems, and the object thereof is a bathroom heater that can adjust the position of the downstream end opening of the air passage up and down, and is excellent in installation properties and efficiently in the bathroom. An object of the present invention is to provide a bathroom heater with high operating performance capable of delivering hot air.

本発明は、浴室の天井裏に配設される下面開放箱状の本体ケースと、本体ケース下面のケース開口部を下方から覆うカバーと、浴室内の空気を本体ケース内に導入する給気手段と、本体ケース内に導入された空気を加熱する加熱手段と、本体ケース内に導入された空気をカバーの吹出口へ導く送風路とを備え、送風路が、給気手段の空気送出部からケース開口部へ向かって延設される本体筒部と、下端開口部が前記吹出口に対向し、本体筒部のケース開口部側の端部に上下移動可能な状態で設けられる可動筒部とで構成された浴室暖房機であって、本体ケースの前壁内側に、可動筒部を本体ケース内の所定の上位置で係合支持可能な係合部が設けられ、可動筒部をカバーにネジ締めするに従って、可動筒部が、前記上位置で係合支持された状態から下方へ移動し、下端開口部の周縁を吹出口の周縁上部に当接させた状態で固定される構成としたものである。 The present invention relates to a bottom-open box-shaped main body case disposed on the ceiling of a bathroom, a cover that covers a case opening on the lower surface of the main body case from below, and air supply means for introducing air in the bathroom into the main body case. And a heating means for heating the air introduced into the main body case, and an air blowing path for guiding the air introduced into the main body case to the blower outlet of the cover, the air blowing path from the air delivery section of the air supply means A main body cylinder extending toward the case opening, a movable cylinder provided in a state in which a lower end opening faces the outlet and is movable up and down at an end of the main body cylinder on the case opening side; The bathroom heater is configured such that an engagement portion capable of engaging and supporting the movable cylinder portion at a predetermined upper position in the main body case is provided inside the front wall of the main body case, and the movable cylinder portion is used as a cover. As the screw is tightened, the movable cylinder is engaged and supported at the upper position. It moves downward from those where the structure is fixed in a state of being contact with the periphery of the lower end opening to the periphery upper portion of the air outlet.

このものでは、設置前に、本体ケースの前壁内側に設けられた係合部によって、可動筒部を本体ケース内の上位置で係合支持させておくことができるから、設置する際、可動筒部とカバーとの固定に手間がかからない。また、本体ケースと送風路との対向する側壁相互間に、バネ部材など本体筒部と可動筒部とを連結させる機構を設ける必要がないから、その分、送風路の左右幅を従来のものより大きく設定することもできる。 In this case, the movable cylinder portion can be engaged and supported at the upper position in the main body case by the engaging portion provided inside the front wall of the main body case before installation. It takes less time to fix the tube and cover. In addition, since there is no need to provide a mechanism for connecting the main body cylinder part and the movable cylinder part, such as a spring member, between the opposing side walls of the main body case and the air supply path, the left and right widths of the air supply path are reduced accordingly. It can also be set larger.

また、本発明は、上記浴室暖房機において、本体ケースの前壁内側に、係合部として送風路の前壁側へ突出する係止片が設けられ、可動筒部の前壁外側に、本体ケースの前壁側へ突出する突起が設けられ、可動筒部を非係合位置から前記上位置まで移動させることで、突起が、係止片または突起の少なくとも何れか一方の弾性力に抗して係止片の上部に移動し係合される構成としたものである。 Further, in the above-described bathroom heater, the present invention is provided with a locking piece protruding toward the front wall side of the air passage as an engaging portion on the inner side of the front wall of the main body case, and on the outer side of the front wall of the movable cylinder portion. A protrusion that protrudes toward the front wall of the case is provided, and the protrusion resists the elastic force of at least one of the locking piece and the protrusion by moving the movable cylinder portion from the non-engagement position to the upper position. Thus, it is configured to move and engage with the upper part of the locking piece.

カバーを本体ケースから取り外した際に可動筒部が弾性力により本体ケース内へ収容されるよう、本体筒部と可動筒部との側壁相互を引張バネで連結したものでは、可動筒部の重量より大きな弾性力を備えた引張バネ、即ち、比較的大型の引張バネが用いられる。そのため、設置する際に、可動部材を本体ケースから引き下ろし難く、設置作業に手間がかかる。また、本体ケースと送風路との対向する側壁相互間により大きな空間を確保する必要もある。 When the cover is removed from the main body case, the side wall of the main body cylindrical portion and the movable cylindrical portion are connected by a tension spring so that the movable cylindrical portion is accommodated in the main body case by elastic force. A tension spring having a larger elastic force, that is, a relatively large tension spring is used. Therefore, when installing, it is difficult to pull down the movable member from the main body case, and installation work takes time. It is also necessary to secure a larger space between the opposing side walls of the main body case and the air passage.

しかしながら、上記発明の浴室暖房機では、可動筒部を本体ケースの上位置まで移動させた際、本体ケースの前壁内側にて可動筒部が弾性を持って係合支持されるから、可動筒部を本体ケースの上位置で仮止めした状態から容易に下方へ移動させることができる。また、本体ケースと送風路との対向する側壁相互間に、可動筒部を本体ケース内の上位置に保持させる機構を設ける必要がないから、その分、送風路の左右幅をより大きく設定することもできる。 However, in the bathroom heater of the above invention, when the movable cylinder portion is moved to the upper position of the main body case, the movable cylinder portion is elastically engaged and supported inside the front wall of the main body case. The part can be easily moved downward from the temporarily fixed state at the upper position of the main body case. Moreover, since it is not necessary to provide a mechanism for holding the movable cylinder portion at the upper position in the main body case between the opposing side walls of the main body case and the air flow path, the left and right widths of the air flow path are set to be larger accordingly. You can also.

また、本発明は、上記浴室暖房機において、本体ケースの前壁内側に、本体筒部に対する可動筒部の前記上位置における上下方向への移動を許容し、前後および左右方向への移動を阻止する案内部が設けられたものである。 Further, in the above-mentioned bathroom heater, the present invention allows the movement of the movable cylinder portion in the upper position with respect to the main body cylinder portion in the vertical direction inside the front wall of the main body case, and prevents the movement in the front-rear and left-right directions. The guide part to be provided is provided.

このものでは、可動筒部をカバーに固定する際に、本体ケースの前壁内側に設けられた案内部によって、可動筒部の前後左右へのずれが防止されるから、下端開口部の周縁と吹出口の周縁上部との間に不要な隙間がより形成され難い。しかも、このものでは、本体ケースと送風路との対向する側壁相互間に、可動筒部の前後および左右方向への移動を防止するための機構を設ける必要がないから、送風路の左右幅をより大きく設定することもできる。 In this case, when the movable cylinder part is fixed to the cover, the guide part provided on the inner side of the front wall of the main body case prevents the movable cylinder part from being displaced from front to back and left and right. An unnecessary gap is less likely to be formed between the upper peripheral edge of the air outlet. Moreover, in this case, it is not necessary to provide a mechanism for preventing the movable cylinder portion from moving in the front-rear and right-and-left directions between the opposing side walls of the main body case and the air passage. It can also be set larger.

以上のように、本発明によれば、送風路の下流端開口の位置を上下に調整可能な浴室暖房機において、可動筒部を本体ケースの前壁内側に係合支持させることで、設置の際に、可動筒部とカバーとの固定に手間がかからないし、送風路の左右幅を従来のものより大きく設定できるから、設置性に優れ、且つ、温風を浴室内に効率良く送出可能な運転性能の高い浴室暖房機を提供できる。 As described above, according to the present invention, in the bathroom heater that can adjust the position of the downstream end opening of the air passage up and down, the movable cylinder portion is engaged and supported on the inner side of the front wall of the main body case, In this case, it does not take time to fix the movable cylinder part and the cover, and the width of the air passage can be set larger than that of the conventional one, so it is easy to install and can send hot air efficiently into the bathroom. A bathroom heater with high driving performance can be provided.

On the other hand, on the inner side of the front wall 11A of the main body case 11, when the movable cylindrical portion 132 is moved to the upper position, it engages with the projection 31 and supports the movable cylindrical portion 132 from below in a substantially L plate shape in side view. The engagement fitting 32 is provided.

係合金具３２の下端には、送風路１３の前壁１３Ａ側へ突起３１の前端より後方位置まで突出する係止片３２１が形成されており、可動筒部１３２を下位置から上方へ移動させた際、係止片３２１の後端は、突起３１の上傾斜面３１１に当接するように構成されている。一方、突起３１は、下端が台部３０に片持ち状に支持されており、後方へ所定以上の押圧力が加わることで、前壁１３２Ａ側へ弾性をもって後退し、上記押圧力が消失すれば、弾性力によって元の突出位置に復帰するよう構成されている。 A locking piece 321 is formed at the lower end of the engagement fitting 32 so as to protrude from the front end of the projection 31 to the rear position toward the front wall 13A of the air passage 13 to move the movable cylinder 132 upward from the lower position. In this case, the rear end of the locking piece 321 is configured to contact the upper inclined surface 311 of the protrusion 31. On the other hand, the lower end of the protrusion 31 is supported in a cantilevered manner on the pedestal 30. When a predetermined pressing force is applied to the rear side, the protrusion 31 is elastically retracted toward the front wall 132A, and the pressing force disappears. It is configured to return to the original protruding position by elastic force.

従って、係止片３２１が上傾斜面３１１に当接した状態からさらに上方へ可動筒部１３２を移動させれば、それに伴って突起３１が係止片３２１により後方へ押されて弾性変形し、係止片３２１の後端を越えて上方へ移動して係合状態となる。このとき、係止片３２１の後端は、突起３１の下傾斜面３１２に当接する。これにより、可動筒部１３２は、本体筒部１３１に対して抜け止め状態でケース内部１０の上位置に係合支持され、略全体がケース内部１０の所定位置に収容された状態とな
る（図５参照）。尚、可動筒部１３２は、工場出荷前の組立段階でケース内部１０の上位置に係合支持させる。このように、設置前に可動筒部１３２をケース内部１０の上位置に係合支持させておけば、カバー１２を本体ケース１１に取り付ける際に可動筒部１３２が作業の邪魔にならないし、カバー１２と可動筒部１３２との接触による破損を防止することもできる。 Therefore, if the movable cylindrical portion 132 is moved further upward from the state in which the locking piece 321 is in contact with the upper inclined surface 311, the protrusion 31 is pushed backward by the locking piece 321 and elastically deformed accordingly. It moves upward beyond the rear end of the locking piece 321 to be engaged. At this time, the rear end of the locking piece 321 contacts the lower inclined surface 312 of the protrusion 31. Thereby, the movable cylinder part 132 is engaged and supported at the upper position of the case interior 10 in a state of being prevented from being detached from the main body cylinder part 131, and substantially the whole is accommodated at a predetermined position in the case interior 10 (FIG. 5). The movable cylinder portion 132 is engaged and supported at the upper position inside the case 10 at the assembly stage before factory shipment. Thus, if the movable cylinder part 132 is engaged and supported at the upper position of the case interior 10 before installation, the movable cylinder part 132 does not interfere with the work when the cover 12 is attached to the main body case 11, and the cover It is also possible to prevent breakage due to contact between 12 and the movable cylinder portion 132.

また、設置する際には、カバー１２を本体ケース１１に取り付けた後、可動筒部１３２を筒固定ネジ１９で本体ケース１１にネジ締めすれば、可動筒部１３２がケース内部１０の上位置に係合支持された仮固定状態から下方側へ移動し、それに伴って突起３１が係止片３２１により後方へ押されて弾性変形する。そしてさらに筒固定ネジ１９をネジ締めすれば、突起３１が係止片３２１から外れて非係合状態となる。これにより、可動筒部１３２が下端開口部２３の周縁を吹出口２２の周縁上面に当接させた状態でカバー１２に固定される（図４参照）。よって、設置の手間が少ない。尚、天井壁４０の厚みや突起３１の大きさ、筒固定ネジ１９の長さによって、可動筒部１３２の下方への移動距離が異なるため、係止片３２１に突起３１が係合支持された状態のまま可動筒部１３２がカバー１２に固定されてもよい。 When installing, after attaching the cover 12 to the main body case 11, the movable cylindrical portion 132 is screwed to the main body case 11 with the cylindrical fixing screw 19, so that the movable cylindrical portion 132 is positioned at the upper position inside the case 10. The projection 31 moves downward from the temporarily fixed state engaged and supported, and accordingly, the projection 31 is pushed backward by the locking piece 321 and elastically deformed. If the tube fixing screw 19 is further tightened, the protrusion 31 is detached from the locking piece 321 and is brought into a non-engagement state. Thereby, the movable cylinder part 132 is fixed to the cover 12 in a state where the peripheral edge of the lower end opening 23 is in contact with the peripheral upper surface of the air outlet 22 (see FIG. 4). Therefore, there is little installation effort. In addition, since the moving distance to the lower part of the movable cylinder part 132 differs depending on the thickness of the ceiling wall 40, the size of the protrusion 31, and the length of the cylinder fixing screw 19, the protrusion 31 is engaged and supported by the locking piece 321. The movable cylinder part 132 may be fixed to the cover 12 in the state.

前壁１３２Ａの外側面には、側面視略Ｌ字板状の軸板３３が上向きに起立形成されている。一方、係合金具３２の上端には、平板状の連結片３２２が後方（送風路１３の前壁１３Ａ側）へ向かって突出形成されている。また、連結片３２２の中央部には、軸板３３の断面形状と略同一の横長矩形状の軸受孔３４が開設されており（図６参照）、可動筒部１３２をケース内部１０の上位置まで移動させた際、軸板３３は、軸受孔３４に上下摺動可能な状態で挿通される。即ち、可動筒部１３２は、ケース内部１０の上位置において、本体筒部１３１に対する上下方向への移動のみ許容され、前後および左右方向への移動は阻止される。 On the outer side surface of the front wall 132A, a shaft plate 33 having a substantially L-shaped plate in a side view is erected upward. On the other hand, a flat connecting piece 322 is formed on the upper end of the engagement fitting 32 so as to protrude rearward (toward the front wall 13A of the air passage 13). In addition, a horizontally-long rectangular bearing hole 34 that is substantially the same as the cross-sectional shape of the shaft plate 33 is formed in the center portion of the connecting piece 322 (see FIG. 6), and the movable cylinder portion 132 is positioned above the case interior 10. The shaft plate 33 is inserted into the bearing hole 34 so as to be slidable up and down. That is, the movable cylinder portion 132 is allowed to move only in the vertical direction with respect to the main body cylinder portion 131 at the upper position inside the case 10 and is prevented from moving in the front-rear and left-right directions.

台部３０の外側面上端には、側面視略Ｌ字板状で且つ正面視略コ字状の引掛けリング３５が形成されている。一方、係合金具３２の係止片３２１の後端には、可動筒部１３２が下位置に移動した際に引掛けリング３５と係合する平板状の爪片３６が上向きに突出形成されている。従って、突起３１と係止片３２１とが非係合状態である場合に、カバー１２が本体ケース１１から取り外されても、可動筒部１３２は、本体ケース１１に引掛かった状態で保持され、落下しない。 A hook ring 35 that is substantially L-shaped in a side view and substantially U-shaped in a front view is formed at the upper end of the outer surface of the base 30. On the other hand, at the rear end of the locking piece 321 of the engagement fitting 32, a flat plate-like claw piece 36 that is engaged with the hook ring 35 when the movable cylindrical portion 132 moves to the lower position is formed to protrude upward. Yes. Therefore, when the projection 31 and the locking piece 321 are in the disengaged state, even when the cover 12 is removed from the main body case 11, the movable cylinder portion 132 is held in a state of being hooked on the main body case 11, Does not fall.

このように、上記浴室暖房機１によれば、バネ部材を用いることなく、本体ケース１１の前壁１１Ａの内側に設けられた係合金具３２によって、可動筒部１３２を本体ケース１１内の上位置に上下摺動可能な状態で仮止め支持させることができるから、設置する際、可動筒部１３２とカバー１２との固定に手間がかからない。よって、設置性が向上する。また、送風路１３および本体ケース１１の対向する側壁相互の間隙１００に、バネ部材など本体筒部１３１と可動筒部１３２とを連結させる機構を設ける必要がないから、その分、送風路１３の左右幅を大きく設定することもできる。よって、暖房運転や乾燥運転時に、温風を浴室４内に効率良く送出でき、運転性能が向上する。 Thus, according to the bathroom heater 1, the movable cylindrical portion 132 is placed on the upper side of the main body case 11 by the engagement fitting 32 provided on the inner side of the front wall 11A of the main body case 11 without using a spring member. Since it can be temporarily fixed and supported while being slidable up and down at a position, it does not take time to fix the movable cylindrical portion 132 and the cover 12 during installation. Therefore, installation property improves. Further, since it is not necessary to provide a mechanism for connecting the main body cylinder part 131 and the movable cylinder part 132 such as a spring member in the gap 100 between the opposing side walls of the air passage 13 and the main body case 11, The left and right width can be set larger. Therefore, warm air can be efficiently sent into the bathroom 4 during heating operation and drying operation, and the driving performance is improved.

また、このものでは、可動筒部１３２をケース内部１０の上位置まで移動させた際、本体ケース１１の前壁１１Ａの内側にて可動筒部１３２が弾性を持って係合支持されるから、可動筒部１３２を本体ケース１１の上位置で仮止めした状態から容易に下方へ移動させることができる。よって、設置性が一層向上する。また、本体ケース１１と送風路１３との対向する側壁相互の間隙１００に、可動筒部１３２をケース内部１０の上位置に保持させる機構を設ける必要がないから、その分、送風路１３の左右幅をより大きく設定することもできる。よって、暖房運転や乾燥運転時に、温風を浴室４内に効率良く送出でき、運転性能が一層向上する。 Further, in this case, when the movable cylinder part 132 is moved to the upper position inside the case 10, the movable cylinder part 132 is elastically engaged and supported inside the front wall 11A of the main body case 11. The movable cylinder portion 132 can be easily moved downward from the state where it is temporarily fixed at the upper position of the main body case 11. Therefore, the installability is further improved. Further, since it is not necessary to provide a mechanism for holding the movable cylindrical portion 132 at the upper position inside the case 10 in the gap 100 between the opposing side walls of the main body case 11 and the air passage 13, The width can be set larger. Therefore, warm air can be efficiently sent into the bathroom 4 during heating operation or drying operation, and the operation performance is further improved.

さらに、このものでは、可動筒部１３２をカバー１２に固定する際、本体ケース１１の前壁１１Ａの内側に設けられた軸受け孔３４によって、可動筒部１３２の前後左右へのずれが防止されるから、下端開口部２３の周縁と吹出口２２の周縁上部との間に不要な隙間がより形成され難い。よって、空気漏れによる運転性能の低下をより確実に防止できる。 Furthermore, in this case, when the movable cylinder part 132 is fixed to the cover 12, the bearing hole 34 provided on the inner side of the front wall 11A of the main body case 11 prevents the movable cylinder part 132 from shifting to the front, rear, left and right. Therefore, it is difficult to form an unnecessary gap between the peripheral edge of the lower end opening 23 and the upper peripheral edge of the air outlet 22. Therefore, it is possible to more reliably prevent a decrease in operating performance due to air leakage.

しかも、このものでは、本体ケース１１と送風路１３との対向する側壁相互の間隙１００に、可動筒部１３２の前後および左右方向への移動を防止するための機構を設ける必要がないから、送風路１３の左右幅をより大きく設定することもできる。よって、暖房運転や乾燥運転時に、温風を浴室４内に効率良く送出でき、運転性能が一層向上する。 In addition, in this case, it is not necessary to provide a mechanism for preventing the movable cylindrical portion 132 from moving in the front-rear and left-right directions in the gap 100 between the opposing side walls of the main body case 11 and the air passage 13. The left and right width of the path 13 can be set larger. Therefore, warm air can be efficiently sent into the bathroom 4 during heating operation or drying operation, and the operation performance is further improved.

尚、上記実施の形態では、可動筒部１３２をカバー１２にネジ締め固定する際、突起３１が弾性変形することで係止片３２１から外れ、非係合状態となるように構成されたものを説明したが、突起３１が可動筒部１３２に固定された状態で設けられており、係合金具３２が前方へ弾性変形することで、突起３１が係止片３２１から外れて非係合状態となるように構成されたものとしてもよい。 In the above embodiment, when the movable cylindrical portion 132 is screwed and fixed to the cover 12, the projection 31 is elastically deformed so that it is disengaged from the locking piece 321 and is in a non-engaged state. As described above, the protrusion 31 is provided in a state of being fixed to the movable cylindrical portion 132, and the protrusion 31 is detached from the locking piece 321 and is in the non-engaged state by the elastic deformation of the engagement fitting 32 forward. It is good also as what was comprised.

また、上記実施の形態では、暖房機能と乾燥機能の両方を有する浴室暖房乾燥機について説明したが、本発明は、排気筒１４や風路切替ダンパ１８を備えていない、暖房機能のみ有する浴室暖房機にも適用できる。 Moreover, in the said embodiment, although the bathroom heating dryer which has both a heating function and a drying function was demonstrated, this invention is not provided with the exhaust pipe 14 or the air path switching damper 18, and the bathroom heating which has only a heating function. It can also be applied to machines.

本発明は、本体筒部１３１の下流端部１３３に、加熱手段として熱交換器１６が組み込まれたものを説明したが、ケース内部１０におけるケース開口部１１０とファン１５との間、即ち、ファン１５の上流位置に熱交換器１６が組み込まれたものにも適用できる。また、熱交換器１６に代えて、電気ヒータが組み込まれた浴室暖房機にも適用できる。 In the present invention, the case where the heat exchanger 16 is incorporated as the heating means at the downstream end 133 of the main body cylindrical portion 131 has been described. However, the case interior 10 has a space between the case opening 110 and the fan 15, that is, the fan. The present invention can also be applied to a structure in which the heat exchanger 16 is incorporated in the upstream position of 15. Moreover, it can replace with the heat exchanger 16 and is applicable also to the bathroom heater incorporating the electric heater.
