Abstract

An object which is subjected to an air flow is neither locally overheated nor locally over-cooled. A fan (23) generates an air flow flowing from an intake opening (21a), passing through a heat exchanger (22), and flowing upward at the front of a casing (21).  On the other hand, a fan (24) generates an air flow flowing from the intake opening (21a) and flowing downward at the front of the casing (21).  These air flows collide with each other in the casing (21) and are ejected forward from an indoor unit (2) through an ejection opening (21b) formed in the front face of the casing (21).

特開平８－１５２１８４号公報（図１）JP-A-8-152184 (FIG. 1)
　特許文献１によると、一方の気流が他方の気流を下方に向かって導くため、比較的幅が狭く流れの整った気流が形成される。このため、かかる気流を冷風や温風として用いる場合、気流と周囲との温度差が大きくなりやすく、風が当たった物体を局所的に冷やし過ぎたり暖め過ぎたりするおそれがある。 According to Patent Document 1, since one air flow guides the other air flow downward, an air flow having a relatively narrow width and a well-formed flow is formed. For this reason, when such an airflow is used as cold air or warm air, the temperature difference between the airflow and the surroundings tends to be large, and there is a possibility that an object hit by the wind will be overcooled or overheated locally.
　本発明の目的は、風を当てた物体が局所的に冷え過ぎたり暖まり過ぎたりしない室内機及び空気調和機を提供することにある。 An object of the present invention is to provide an indoor unit and an air conditioner in which an object to which a wind is applied is not too cold or too warm locally.
　本発明に係る第１の発明の室内機は、熱交換器及び送風機を収容し且つ吹き出し口を有するケーシングを備え、前記ケーシングの内部には、前記送風機によって形成される気流が通過することで前記吹き出し口に到達する複数の通風路が設けられており、前記複数の通風路をそれぞれ通過した複数の気流は、前記ケーシング内において衝突した後で前記吹き出し口から吹き出される。 An indoor unit according to a first aspect of the present invention includes a casing that houses a heat exchanger and a blower and has a blow-out port, and an air flow formed by the blower passes through the casing so as to pass through the casing. A plurality of ventilation paths reaching the outlet are provided, and the plurality of airflows respectively passing through the plurality of ventilation paths are blown out from the outlet after colliding in the casing.
　この室内機では、外部に比べて圧力の高いケーシング内で気流を衝突させることにより、ランダムな気流からなる風を吹き出すことができる。したがって、周囲の空気と混ざりやすく広がりのある風が形成されるため、気流と周囲との温度差が大きくなりにくく、風を当てた物体を局所的に冷やし過ぎたり暖めすぎたりすることが防止される。また、気流が発生した位置に近いところで衝突するため、空調空間に対してロスが小さくなる。つまり、発生上流であればあるほど、空調したい空間全域に気流を作用させることができる。一方、下流になるにつれて、スポット的な効果となってしまい、空間の空調としてロスが増える。 In this indoor unit, it is possible to blow out a wind consisting of a random air current by colliding the air current in a casing having a higher pressure than the outside. As a result, a wide and easy-to-mix wind with the surrounding air is formed, so that the temperature difference between the air flow and the surroundings is unlikely to be large, and it is possible to prevent objects that are exposed to the wind from being overcooled or overheated locally. The Further, since the collision occurs near the position where the airflow is generated, the loss is reduced with respect to the air-conditioned space. In other words, the more upstream the generation, the more air current can be applied to the entire space to be air-conditioned. On the other hand, it becomes a spot effect as it goes downstream, and the loss increases as air conditioning of the space.
　第２の発明の室内機は、第１の発明に係る室内機であって、前記複数の通風路の少なくとも１つの通風路上に、前記通風路を通過する気流の方向を規制する整流ガイドが配置される。 An indoor unit according to a second aspect of the present invention is the indoor unit according to the first aspect of the present invention, wherein a rectifying guide for restricting the direction of airflow passing through the ventilation path is disposed on at least one ventilation path of the plurality of ventilation paths. Is done.
　この室内機では、気流同士が衝突しやすい通風路を形成することができる。 In this indoor unit, it is possible to form a ventilation path where airflows easily collide with each other.
　第３の発明の室内機は、第１又は第２の発明に係る室内機であって、前記複数の通風路の少なくとも２つの通風路上に、互いに異なる送風機が配置される。 The indoor unit of the third invention is the indoor unit according to the first or second invention, and different blowers are arranged on at least two ventilation paths of the plurality of ventilation paths.
　この室内機では、２つの通風路のそれぞれに送風機が配置されるので、各通風路を通過する気流を確実に形成することができる。 In this indoor unit, since a blower is disposed in each of the two ventilation paths, an airflow passing through each ventilation path can be reliably formed.
　第４の発明の室内機は、第１～第３の発明のいずれかに係る室内機であって、前記複数の通風路の一部の通風路上だけに前記熱交換器が配置される。 An indoor unit according to a fourth aspect of the present invention is the indoor unit according to any of the first to third aspects, wherein the heat exchanger is disposed only on a part of the plurality of ventilation paths.
　この室内機では、冷却された気流や加熱された気流を、熱交換器を通さない気流と混ぜることで、適度な温度に調整して吹き出すことができる。 In this indoor unit, the cooled airflow or the heated airflow can be mixed with the airflow that does not pass through the heat exchanger, and adjusted to an appropriate temperature and blown out.
　第５の発明の室内機は、第１～第４の発明のいずれかに係る室内機であって、前記ケーシングの内部には、４つの通風路が設けられており、前記４つの通風路をそれぞれ通過した気流は、前記ケーシング内において上下左右の４方向から衝突した後で前記吹き出し口から吹き出される。 An indoor unit according to a fifth aspect of the present invention is the indoor unit according to any one of the first to fourth aspects of the invention, wherein four air passages are provided inside the casing, and the four air passages are provided. The airflows that have passed through the airflow are blown out from the air outlet after colliding from the four directions of up, down, left and right in the casing.
　この室内機では、気流を４方から衝突させるので、衝突後の気流を安定に形成することができる。 In this indoor unit, since the airflow is collided from four directions, the airflow after the collision can be stably formed.
　第６の発明の空気調和機は、第１～第５の発明のいずれかに係る室内機を備えている。 An air conditioner according to a sixth aspect includes the indoor unit according to any one of the first to fifth aspects.
　この室内機では、第１～第５の発明の室内機を備えることにより、幅が狭い流れの整った風と比べて、気流と周囲との温度差が大きくなりにくく、風を当てた物体を局所的に冷やし過ぎることが防止された空気調和機が実現する。 In this indoor unit, by providing the indoor units of the first to fifth inventions, the temperature difference between the airflow and the surroundings is less likely to be large compared to a narrow-flowing wind, and the object to which the wind is applied An air conditioner that is prevented from being overcooled locally is realized.
　以上の説明に述べたように、本発明によれば、以下の効果が得られる。 As described in the above description, according to the present invention, the following effects can be obtained.
　第１の発明では、外部に比べて圧力の高いケーシング内で気流を衝突させることにより、ランダムな気流からなる風を吹き出すことができる。したがって、幅が狭い流れの整った風と比べて、気流と周囲との温度差が大きくなりにくく、風を当てた物体を局所的に冷やし過ぎることが防止される。また、気流が発生した位置に近いところで衝突するため、空調空間に対してロスが小さくなる。つまり、発生上流であればあるほど、空調したい空間全域に気流を作用させることができる。一方、下流になるにつれて、スポット的な効果となってしまい、空間の空調としてロスが増える。 In the first invention, it is possible to blow out a wind consisting of a random air current by colliding the air current in a casing having a higher pressure than the outside. Therefore, the temperature difference between the airflow and the surroundings is less likely to be larger than that of the narrowly arranged wind, and it is possible to prevent the object to which the wind is applied from being excessively cooled. Further, since the collision occurs near the position where the airflow is generated, the loss is reduced with respect to the air-conditioned space.

　以下、本発明に係る空気調和機の実施の形態について、図面を参照しつつ説明する。 Hereinafter, embodiments of an air conditioner according to the present invention will be described with reference to the drawings.
（第１の実施形態） (First embodiment)
　図１の空気調和機１は、室内の壁などに取り付けられる室内機２と、室外に設置される室外機３とを備えている。室外機３と室内機２との間には、冷媒となる流体の流路が設けられている。 1 includes an indoor unit 2 attached to an indoor wall or the like, and an outdoor unit 3 installed outside the room. Between the outdoor unit 3 and the indoor unit 2, a fluid flow path serving as a refrigerant is provided.
　室内機２は、ケーシング２１と、ケーシング２１に収容された熱交換器２２と、送風機２３及び２４とを備えている。ケーシング２１は、室内機２の左右方向に長尺な直方体型の概略形状を有している。図１には、ケーシング２１の左側の構成が実線で示されていると共に、右側の構成が破線で示されている。ケーシング２１の内部には、直方体型の概略形状を有する空間が形成されている。熱交換器２２、送風機２３及び２４は、ケーシング２１のかかる内部空間に収容されている。 The indoor unit 2 includes a casing 21, a heat exchanger 22 accommodated in the casing 21, and blowers 23 and 24. The casing 21 has a substantially rectangular parallelepiped shape that is long in the left-right direction of the indoor unit 2. In FIG. 1, the configuration on the left side of the casing 21 is indicated by a solid line, and the configuration on the right side is indicated by a broken line. A space having a substantially rectangular parallelepiped shape is formed in the casing 21. The heat exchanger 22 and the fans 23 and 24 are accommodated in the internal space of the casing 21.
　ケーシング２１の上面には、ケーシング２１の外部空間と内部空間とを連通させる複数の空気の取り入れ口２１ａが形成されている。ケーシング２１の内部空間には、取り入れ口２１ａを通じて外部から空気が取り入れられる。ケーシング２１の前面には、ケーシング２１の外部空間と内部空間とを連通させる空気の吹き出し口２１ｂが形成されている。吹き出し口２１ｂは、ケーシング２１の前面より一回り小さい長方形の概略形状を有している。 On the upper surface of the casing 21, a plurality of air intake ports 21 a are formed that allow the external space and the internal space of the casing 21 to communicate with each other. Air is taken into the internal space of the casing 21 from the outside through the intake port 21a. On the front surface of the casing 21, an air outlet 21 b is formed to communicate the external space and the internal space of the casing 21. The outlet 21b has a rectangular shape that is slightly smaller than the front surface of the casing 21.
　送風機２３は、図１に示すように、ケーシング２１内において左右方向に沿って配置されている。また、送風機２３は、図２に示すように、ケーシング２１の中央付近に配置されている。送風機２３は、取り入れ口２１ａを介してケーシング２１内に空気を取り込むと共に、取り込んだ空気をケーシング２１の下部に向かわせるような気流を発生させる。 As shown in FIG. 1, the blower 23 is disposed in the casing 21 along the left-right direction. Moreover, the air blower 23 is arrange | positioned in the center vicinity of the casing 21, as shown in FIG. The blower 23 takes in air into the casing 21 through the intake port 21 a and generates an air flow that directs the taken-in air toward the lower portion of the casing 21.
　熱交換器２２は、ケーシング２１内において、取り入れ口２１ａの下方に配置されている。熱交換器２２は、図１に示すように左右方向に沿って配置されている。熱交換器２２の上部は、図２に示すように、取り入れ口２１ａと送風機２３の間に配置されている。これによって、取り入れ口２１ａから取り込まれた空気が熱交換器２２を通って送風機２３へと向かうようになっている。また、熱交換器２２の前部は、吹き出し口２１ｂと対向するように上下方向に延びている。 The heat exchanger 22 is disposed in the casing 21 below the intake port 21a. The heat exchanger 22 is disposed along the left-right direction as shown in FIG. The upper part of the heat exchanger 22 is arrange | positioned between the inlet 21a and the air blower 23, as shown in FIG. Thereby, the air taken in from the intake port 21a passes through the heat exchanger 22 and goes to the blower 23. Further, the front portion of the heat exchanger 22 extends in the vertical direction so as to face the blowout port 21b.
　ケーシング２１内には、室外機３からの冷媒を熱交換器２２に供給する図示しない配管が導入されている。この熱交換器２２は、冷房運転時には冷媒の蒸発器として機能し、暖房運転時には冷媒の凝縮器として機能する。具体的には、冷房運転時には、当該熱交換器２２には室外機３から低温且つ低圧の液体状の冷媒が供給され、その冷媒は熱交換器２２において蒸発する。これによって、熱交換器２２の周囲の空気が冷却される。また、暖房運転時には、当該熱交換器２２には室外機３から高温且つ高圧の気体上の冷媒が供給され、その冷媒は熱交換器２２において凝縮する。これによって、熱交換器２２の周囲の空気が加熱される。また、ケーシング２１内には、熱交換器２２からの冷媒を室外機３へと回収する図示しない配管が導入されており、熱交換器２２において蒸発又は凝縮した冷媒は室外機３へと回収される。 In the casing 21, a pipe (not shown) for supplying the refrigerant from the outdoor unit 3 to the heat exchanger 22 is introduced. The heat exchanger 22 functions as a refrigerant evaporator during the cooling operation, and functions as a refrigerant condenser during the heating operation. Specifically, during the cooling operation, the heat exchanger 22 is supplied with a low-temperature and low-pressure liquid refrigerant from the outdoor unit 3, and the refrigerant evaporates in the heat exchanger 22. Thereby, the air around the heat exchanger 22 is cooled. Further, during the heating operation, the heat exchanger 22 is supplied with a refrigerant on the high-temperature and high-pressure gas from the outdoor unit 3, and the refrigerant is condensed in the heat exchanger 22. Thereby, the air around the heat exchanger 22 is heated. In the casing 21, a pipe (not shown) for recovering the refrigerant from the heat exchanger 22 to the outdoor unit 3 is introduced, and the refrigerant evaporated or condensed in the heat exchanger 22 is recovered to the outdoor unit 3. The
　ケーシング２１内において、熱交換器２２と吹き出し口２１ｂとの間には、遮蔽板２５が設けられている。遮蔽板２５は、図１に示すように、ケーシング２１の左右方向に沿って延びている。遮蔽板２５の熱交換器２２の上部と後述する送風機２４との間に配置される上部は、図２に示すように、取り入れ口２１ａから吹き出し口２１ｂに向かって、熱交換器２２の上部に沿って斜めに延びている。また、遮蔽板２５の熱交換器２２の下部と吹き出し口２１ｂとの間に配置される下部は、熱交換器２２の下部に沿って上下方向に延びている。遮蔽板２５の下端は、後述の整流ガイド２７が配置された位置付近に配置されている。 In the casing 21, a shielding plate 25 is provided between the heat exchanger 22 and the outlet 21b. As shown in FIG. 1, the shielding plate 25 extends along the left-right direction of the casing 21. As shown in FIG. 2, the upper part of the shielding plate 25 disposed between the upper part of the heat exchanger 22 and the blower 24 described later is located on the upper part of the heat exchanger 22 from the intake port 21a toward the outlet port 21b. It runs diagonally along. Moreover, the lower part arrange | positioned between the lower part of the heat exchanger 22 of the shielding board 25 and the blower outlet 21b is extended in the up-down direction along the lower part of the heat exchanger 22. FIG. The lower end of the shielding plate 25 is disposed in the vicinity of a position where a later-described rectifying guide 27 is disposed.
　送風機２４は、図１に示すように、ケーシング２１の左右方向に沿って配置されている。また、送風機２４は、図２に示すように、遮蔽板２５の上部とケーシング２１の前壁との間に配置されている。送風機２３は、取り入れ口２１ａを介してケーシング２１内に空気を取り込むと共に、取り込んだ空気をケーシング２１の下部に向かわせるような気流を発生させる。 The blower 24 is arranged along the left-right direction of the casing 21 as shown in FIG. Moreover, the air blower 24 is arrange | positioned between the upper part of the shielding board 25 and the front wall of the casing 21, as shown in FIG. The blower 23 takes in air into the casing 21 through the intake port 21 a and generates an air flow that directs the taken-in air toward the lower portion of the casing 21.
　ケーシング２１には、内部空間に形成される気流の方向を規制する整流ガイド２６及び２７が設けられている。整流ガイド２６は、ケーシング２１の前壁と上壁との間に形成された角部に設けられ、整流ガイド２７は、ケーシング２１の前壁と下壁との間に形成された角部に設けられている。整流ガイド２６及び２７は、図１に示すように、いずれもケーシング２１の左右方向に沿って延びている。また、整流ガイド２６及び２７は、図２に示すように、いずれも直角三角形の断面形状を有している。そして、整流ガイド２６及び２７において直角三角形の斜辺に相当する面２６ａ及び２７ａは、それぞれ、ケーシング２１の吹き出し口２１ｂに向かって斜め下方及び斜め上方に傾斜している。なお、面２６ａ及び２７ａは、それぞれ、曲面であってもよい。 The casing 21 is provided with rectifying guides 26 and 27 for regulating the direction of airflow formed in the internal space. The rectifying guide 26 is provided at a corner portion formed between the front wall and the upper wall of the casing 21, and the rectifying guide 27 is provided at a corner portion formed between the front wall and the lower wall of the casing 21. It has been. As shown in FIG. 1, the rectifying guides 26 and 27 both extend along the left-right direction of the casing 21. Further, as shown in FIG. 2, each of the rectifying guides 26 and 27 has a right-angled triangular cross-sectional shape. In the rectifying guides 26 and 27, the surfaces 26 a and 27 a corresponding to the oblique sides of the right triangle are inclined obliquely downward and obliquely upward, respectively, toward the outlet 21 b of the casing 21. Each of the surfaces 26a and 27a may be a curved surface.
　次に、室内機２が発生させる気流について説明する。図２には、ケーシング２１の内部で発生する気流の一例である気流Ａと気流Ｂとが、矢印付きの実線で示されている。送風機２３が作動すると、図２の気流Ａに示すように、ケーシング２１の上壁の取り入れ口２１ａを通じて空気がケーシング２１内に流入する。かかる空気は、熱交換器２２を通って送風機２３に到達する。送風機２３に到達した空気は、さらにケーシング２１内の下部へと向かい、遮蔽板２５の下方を通って前方の整流ガイド２７へと到達する。整流ガイド２７には、上記の通り斜め上方に傾斜した面２７ａが形成されている。このため、整流ガイド２７に到達した空気は、整流ガイド２７の面２７ａによって流れを規制されつつ円滑に上方へと向かう。 Next, the airflow generated by the indoor unit 2 will be described. In FIG. 2, an airflow A and an airflow B, which are examples of the airflow generated inside the casing 21, are indicated by solid lines with arrows. When the blower 23 is activated, air flows into the casing 21 through the intake port 21a on the upper wall of the casing 21 as shown in the airflow A in FIG. Such air reaches the blower 23 through the heat exchanger 22. The air that has reached the blower 23 further travels downward in the casing 21, passes under the shielding plate 25, and reaches the front rectifying guide 27. As described above, the rectifying guide 27 has a surface 27a that is inclined obliquely upward. For this reason, the air that has reached the rectifying guide 27 smoothly moves upward while its flow is restricted by the surface 27 a of the rectifying guide 27.
　一方、送風機２４が作動すると、図２の気流Ｂに示すように、ケーシング２１に形成された取り入れ口２１ａのうち、前方寄りの取り入れ口２１ａを通じて空気がケーシング２１内に流入する。かかる空気は、ケーシング２１の前壁と上壁との間の角部付近を、ケーシング２１内の下方へと向かう。ここで、ケーシング２１の前壁と上壁との間の角部には、整流ガイド２６が配置されている。そして、整流ガイド２６には、上記の通り斜め下方に傾斜した面２６ａが形成されている。また、送風機２４と熱交換器２２との間には遮蔽板２５が配置されており、これによって、送風機２４へと流入した空気が熱交換器２２を介して送風機２４より送風力の大きい送風機２３へと引き込まれるのが防止されている。したがって、送風機２４によってケーシング２１内に流入した空気は、整流ガイド２６の面２６ａによって流れを規制されつつ円滑に下方へと向かう。 On the other hand, when the blower 24 is operated, air flows into the casing 21 through the inlet 21a closer to the front among the inlets 21a formed in the casing 21, as shown in the air flow B of FIG. Such air travels downward in the casing 21 in the vicinity of the corner between the front wall and the upper wall of the casing 21. Here, a straightening guide 26 is disposed at a corner between the front wall and the upper wall of the casing 21. The rectifying guide 26 is formed with a surface 26a inclined obliquely downward as described above. In addition, a shielding plate 25 is disposed between the blower 24 and the heat exchanger 22, so that the air that flows into the blower 24 has a larger blowing power than the blower 24 through the heat exchanger 22. It is prevented from being drawn into. Therefore, the air that has flowed into the casing 21 by the blower 24 is smoothly directed downward while the flow is restricted by the surface 26 a of the rectifying guide 26.
　このように、ケーシング２１内には、（１）上記した気流Ａが通過する通風路であって、取り入れ口２１ａからの空気が、遮蔽板２５より後方において熱交換器２２を通過し、遮蔽板２５の下方を通って遮蔽板２５の前方へと回りこむ通風路と、（２）上記した気流Ｂが通過する通風路であって、取り入れ口２１ａからの空気が、遮蔽板２５より前方において下方へと向かう通風路とが設けられることになる。これらの通風路は、遮蔽板２５によって互いに隔てられており、整流ガイド２６及び２７によって空気の流れが規制されている。 Thus, in the casing 21, (1) the above-described airflow path through which the airflow A passes, the air from the intake port 21 a passes through the heat exchanger 22 behind the shielding plate 25, and the shielding plate A ventilation path that passes around the front of the shielding plate 25 through the lower part of the shielding plate 25, and (2) a ventilation path through which the air flow B passes, and the air from the intake port 21a is lower in front of the shielding plate 25. Ventilation path to go to. These ventilation paths are separated from each other by a shielding plate 25, and the flow of air is restricted by rectifying guides 26 and 27.
　そして、気流Ａと気流Ｂとは、吹き出し口２１ｂと遮蔽板２５との間の領域Ｓ１において、上下方向から互いに衝突する。衝突した空気は、この領域Ｓ１の開放側、つまり吹き出し口２１ｂが形成された方に向かい、吹き出し口２１ｂを通じてケーシング２１の外部へと吹き出される。これによって、吹き出し口２１ｂから室内機２の前方へと向かう風Ｃが形成される。 The airflow A and the airflow B collide with each other in the vertical direction in the region S1 between the outlet 21b and the shielding plate 25. The collided air is blown out of the casing 21 through the blowout port 21b toward the open side of the region S1, that is, the direction where the blowout port 21b is formed. Thereby, the wind C which goes to the front of the indoor unit 2 from the blower outlet 21b is formed.
　このように形成される風Ｃには、以下のような特徴がある。上記のように、気流Ａ及びＢは、ケーシング２１の外部空間と比べて圧力の高いケーシング２１の内部空間において互いに衝突する。かかる衝突によって、吹き出し口２１ｂから吹き出された空気中には、向きや強さが一様でない気流が含まれる。図２の領域Ｓ２には、かかる気流の一例が矢印付きの実線で示されている。風Ｃは、このような向きや強さが一様でない気流から構成されることにより、周囲の空気と混ざりやすく、幅の広いものとなる。 The wind C thus formed has the following characteristics. As described above, the airflows A and B collide with each other in the internal space of the casing 21 having a higher pressure than the external space of the casing 21. Due to such a collision, the air blown from the blowout port 21b includes an airflow whose direction and strength are not uniform. In the region S2 of FIG. 2, an example of such airflow is indicated by a solid line with an arrow. The wind C is composed of an air flow having a non-uniform direction and strength, so that the wind C is easily mixed with the surrounding air and becomes wide.
［本実施形態の室内機２の特徴］
　以上説明したように、本実施形態の室内機２によると、ケーシング２１内に２つの通風路が設けられ、これらの通風路を通った気流同士がケーシング２１内で衝突する。これによって、ランダムな気流からなる風が吹き出し口２１ｂから吹き出される。この風は、周囲の空気と混ざりやすく、幅の広いものである。一方で、室内機内で気流同士が衝突せず、整流された気流が吹き出される場合には、幅が狭く流れの整った主流が形成されやすい。かかる主流は周囲の空気と混ざりにくいため、気流と周囲との温度差が大きくなる。したがって、かかる風を人に当てると、局所的に冷え過ぎる不快な感覚を与えるおそれがある。 [Features of indoor unit 2 of this embodiment]
As described above, according to the indoor unit 2 of the present embodiment, two ventilation paths are provided in the casing 21, and airflows that have passed through these ventilation paths collide in the casing 21. Thereby, the wind which consists of random air currents blows off from the blower outlet 21b. This wind is easy to mix with the surrounding air and is wide. On the other hand, when the airflows do not collide with each other in the indoor unit and the rectified airflow is blown out, a main stream having a narrow width and a well-balanced flow is easily formed. Since the main flow is difficult to mix with the surrounding air, the temperature difference between the air flow and the surrounding becomes large. Therefore, when such a wind is applied to a person, there is a risk of giving an unpleasant feeling that is too cold locally.
　これに対して、室内機２による風は、上記のような主流が形成されにくく、周囲の空気と混ざりやすいものであるため、周囲の空気との温度差が大きくなりにくい。また、幅の広い風であるため、広い範囲に風を当てることができる。したがって、物体に当てても局所的に冷やし過ぎたりしなくなり、人に当てた場合にも冷え過ぎる感覚を与えにくくなる。さらに、周囲の空気と混ざりやすい気流を形成するので、室内機２が設置された空間の空調効果を向上させ、エネルギーの消費を抑えることができる。 On the other hand, the wind generated by the indoor unit 2 is less likely to form the main stream as described above and easily mixes with the surrounding air, so that the temperature difference from the surrounding air is unlikely to increase. Further, since the wind is wide, it is possible to apply wind to a wide range. Therefore, even if it hits an object, it does not cool too much locally, and when it hits a person, it becomes difficult to give a sense of being too cold. Furthermore, since an air flow that easily mixes with the surrounding air is formed, the air conditioning effect of the space in which the indoor unit 2 is installed can be improved, and energy consumption can be suppressed.
　また、２つの通風路の一方（気流Ａにかかる通風路）には熱交換器２２が配置されているのに対して、他方（気流Ｂにかかる通風路）には熱交換器が配置されていない。これによって、熱交換器２２を通過して冷却された気流と、熱交換器２２を通過せず外部の気温のままの気流とが、互いに衝突され、吹き出し口２１ｂから吹き出されることとなる。これによって、熱交換器２２で冷やされ過ぎた気流を適度な温度にして吹き出し口２１ｂから吹き出させることができる。 In addition, the heat exchanger 22 is disposed in one of the two ventilation paths (the ventilation path for the airflow A), whereas the heat exchanger is disposed in the other (the ventilation path for the airflow B). Absent. As a result, the airflow that has been cooled by passing through the heat exchanger 22 and the airflow that has not passed through the heat exchanger 22 and remains at the outside air temperature collide with each other and are blown out from the air outlet 21b. Thereby, the air flow that has been cooled by the heat exchanger 22 can be blown out from the outlet 21b at an appropriate temperature.
　また、整流ガイド２６及び２７により、２つの気流を互いに衝突させやすいような通風路を形成することができる。 Also, the air flow guides 26 and 27 can form a ventilation path that makes the two airflows easily collide with each other.
　なお、本実施形態とは異なり、ケーシング２１の外部で２つの気流を衝突させることも考えられる。しかし、この場合には、衝突の際の圧力が衝突位置の周囲へと逃げやすく、衝突後にランダムな風を発生させにくい。これに対して本実施形態は、２つの気流を圧力の高いケーシング２１内で衝突させるため、上記のような風を発生させやすくなっている。 Note that, unlike the present embodiment, it is also conceivable that two airflows collide outside the casing 21. However, in this case, the pressure at the time of the collision easily escapes around the collision position, and it is difficult to generate a random wind after the collision. On the other hand, in the present embodiment, since the two airflows collide with each other in the casing 21 having a high pressure, the above-described wind is easily generated.
（第２の実施形態）
　図３～図５は、本発明の別の実施形態である第２の実施形態に係る室内機２０２の図である。室内機２０２は、第１の実施形態の室内機２の代わりに採用できるものである。 (Second Embodiment)
3 to 5 are views of the indoor unit 202 according to the second embodiment which is another embodiment of the present invention. The indoor unit 202 can be employed instead of the indoor unit 2 of the first embodiment.
　室内機２０２は、熱交換器２２及び送風機２４を有する本体２１０と、本体２１０の前面に配置されたガイドユニット２３０とを有している。図３、図５に示すように、本体２１０は、ケーシング２２１を有しており、熱交換器２２及び送風機２４はケーシング２２１内に収容されている。ケーシング２２１は、直方体型の概略形状を有しており、上面に複数の空気の取り入れ口２２１ａが形成されている。ケーシング２２１は、図５に示すように、前方に向かって開口している。なお、熱交換器２２及び送風機２４については、第１の実施形態と同様の構成であるため、説明を省略する。 The indoor unit 202 includes a main body 210 having the heat exchanger 22 and the blower 24, and a guide unit 230 disposed on the front surface of the main body 210. As shown in FIGS. 3 and 5, the main body 210 has a casing 221, and the heat exchanger 22 and the blower 24 are accommodated in the casing 221. The casing 221 has a substantially rectangular parallelepiped shape, and a plurality of air intake ports 221a are formed on the upper surface. As shown in FIG. 5, the casing 221 opens forward. In addition, about the heat exchanger 22 and the air blower 24, since it is the structure similar to 1st Embodiment, description is abbreviate | omitted.
　ガイドユニット２３０は、図３～図５に示すように、直方体型の概略形状を有するケーシング２３１を有しており、ケーシング２３１の背面は本体２１０の前面に固定されている。ケーシング２３１には四角錐型の内部空間が形成されている。 3 to 5, the guide unit 230 has a casing 231 having a substantially rectangular parallelepiped shape, and the back surface of the casing 231 is fixed to the front surface of the main body 210. The casing 231 has a quadrangular pyramid internal space.
　ケーシング２３１の前面には、図３、図５に示すように、ケーシング２３１の内部空間とケーシング２３１の前方の外部空間とを連通させる空気の吹き出し口２３１ａが形成されている。吹き出し口２３１ａは、ケーシング２３１の前面より一回り小さい長方形の形状を有している。ケーシング２３１の背面には、図４、図５に示すように、通風口２３１ｂが形成されている。通風口２３１ｂは、ケーシング２３１の下部に形成されており、ケーシング２３１の左右方向に沿って延びている。通風口２３１ｂは、図５に示すように、本体２１０の内部空間と連通しており、送風機２４によって本体２１０内に形成された気流をガイドユニット２３０内に導入する導入口となっている。 As shown in FIGS. 3 and 5, an air outlet 231 a is formed on the front surface of the casing 231 so as to allow communication between the internal space of the casing 231 and the external space in front of the casing 231. The outlet 231a has a rectangular shape that is slightly smaller than the front surface of the casing 231. As shown in FIGS. 4 and 5, a ventilation port 231 b is formed on the back surface of the casing 231. The ventilation opening 231 b is formed in the lower part of the casing 231 and extends along the left-right direction of the casing 231. As shown in FIG. 5, the air vent 231 b communicates with the internal space of the main body 210 and serves as an inlet for introducing the airflow formed in the main body 210 by the blower 24 into the guide unit 230.
　ケーシング２３１内には、分配ガイド２３２が収容されている。分配ガイド２３２は、四角錐型の概略形状を有しており、この四角錘の底面２３２ａが前方に面するように配置されている。底面２３２ａは、吹き出し口２３１ａより若干大きい長方形の形状を有しており、正面視すると、底面２３２ａの４辺が吹き出し口２３１ａの４辺を囲むように配置されている。 A distribution guide 232 is accommodated in the casing 231. The distribution guide 232 has a quadrangular pyramid shape and is arranged so that the bottom surface 232a of this square pyramid faces forward. The bottom surface 232a has a rectangular shape slightly larger than the air outlet 231a, and is arranged so that the four sides of the bottom surface 232a surround the four sides of the air outlet 231a when viewed from the front.
　分配ガイド２３２の頂点２３２ｆは、図５に示すように、通風口２３１ｂに対応する位置に配置されている。また、この頂点２３２ｆは、ガイドユニット２３０の左右方向に関してほぼ中央に配置されており、底面２３２ａの下端より上側に配置されている。 As shown in FIG. 5, the vertex 232f of the distribution guide 232 is disposed at a position corresponding to the vent 231b. Further, the vertex 232f is disposed substantially at the center in the left-right direction of the guide unit 230, and is disposed above the lower end of the bottom surface 232a.
　分配ガイド２３２は、頂点２３２ｆから底面２３２ａの４辺に向かって延びる側面２３２ｂ～２３２ｅを有している。側面２３２ｅは、図５に示すように、頂点２３２ｆからケーシング２３１内の床面に沿って、底面２３２ａの４辺のうち正面視で下側の辺に向かって延びている。側面２３２ｂ（図４参照）は、頂点２３２ｆから、底面２３２ａの４辺のうち正面視で右側の辺に向かって延びている。側面２３２ｃは、頂点２３２ｆから、底面２３２ａの４辺のうち正面視で上側の辺に向かって延びている。側面２３２ｄ（図４参照）は、頂点２３２ｆから、底面２３２ａの４辺のうち正面視で左側の辺に向かって延びている。 The distribution guide 232 has side surfaces 232b to 232e extending from the vertex 232f toward the four sides of the bottom surface 232a. As shown in FIG. 5, the side surface 232 e extends from the apex 232 f along the floor surface in the casing 231 toward the lower side in front view among the four sides of the bottom surface 232 a. The side surface 232b (see FIG. 4) extends from the vertex 232f toward the right side of the four sides of the bottom surface 232a in front view. The side surface 232c extends from the vertex 232f toward the upper side of the four sides of the bottom surface 232a in front view. The side surface 232d (see FIG. 4) extends from the vertex 232f toward the left side of the four sides of the bottom surface 232a in front view.
　分配ガイド２３２は、図示しない仕切部を介してケーシング２３１内の４つの角に固定されている。仕切部は、分配ガイド２３２の４つの角に設置されており、分配ガイド２３２からケーシング２３１の角部に向かって延びている。 The distribution guide 232 is fixed to four corners in the casing 231 through a partition portion (not shown). The partition portions are installed at four corners of the distribution guide 232 and extend from the distribution guide 232 toward the corner portion of the casing 231.
　ケーシング２３１内には、気流の方向を規制する整流ガイド２２６及び２２７が設けられている。整流ガイド２２６は、ケーシング２３１の前壁と上壁との間に形成された角部に設けられ、整流ガイド２２７は、ケーシング２３１の前壁と下壁との間に形成された角部に設けられている。整流ガイド２２６及び２２７は、第１の実施形態の整流ガイド２６及び２７と同様に、直角三角形の断面形状を有している。そして、その斜辺に相当する面がケーシング２３１内に向かって斜め下方及び上方にそれぞれ面するように配置されている。 In the casing 231, straightening guides 226 and 227 for regulating the direction of airflow are provided. The rectifying guide 226 is provided at a corner portion formed between the front wall and the upper wall of the casing 231, and the rectifying guide 227 is provided at a corner portion formed between the front wall and the lower wall of the casing 231. It has been. The rectifying guides 226 and 227 have a right triangular cross-sectional shape, similar to the rectifying guides 26 and 27 of the first embodiment. And it arrange | positions so that the surface equivalent to the oblique side may face diagonally downward and upward toward the inside of the casing 231, respectively.
　次に、室内機２０２が発生させる気流について、図４、図５を参照しつつ説明する。図４、図５において、矢印付き実線Ｄ～Ｉは、室内機２内で発生する気流の一例を示している。送風機２４が作動すると、取り入れ口２２１ａから熱交換器２２を通過して通風口２３１ｂに向かう気流Ｄが発生する。通風口２３１ｂからケーシング２３１に流入した気流Ｄは、分配ガイド２３２によって、側面２３２ｂ～２３２ｅのそれぞれに沿った気流Ｅ～Ｈに分配される。このように分配された気流Ｅ～Ｈは、分配ガイド２３２の底面２３２ａの４辺に到達すると、分配ガイド２３２の前方へと回りこむ。 Next, the airflow generated by the indoor unit 202 will be described with reference to FIGS. 4 and 5, solid lines D to I with arrows indicate examples of airflow generated in the indoor unit 2. When the blower 24 is activated, an airflow D is generated from the intake port 221a through the heat exchanger 22 toward the ventilation port 231b. The airflow D flowing into the casing 231 from the ventilation opening 231b is distributed by the distribution guide 232 into the airflows E to H along the side surfaces 232b to 232e. When the airflows E to H distributed in this way reach the four sides of the bottom surface 232 a of the distribution guide 232, the airflows E to H wrap around the front of the distribution guide 232.
　例えば、図５に示すように、側面２３２ｃに沿った気流Ｆは、底面２３２ａの上端に到達すると、整流ガイド２２６によって流れの方向を規制され、底面２３２ａに沿って下方に向かう気流Ｉとなる。一方、側面２３２ｅに沿った気流Ｈは、底面２３２ａの下端に到達すると、整流ガイド２２７によって流れの方向を規制され、底面２３２ａに沿って上方に向かう。同様に、側面２３２ｂや側面２３２ｄに沿った気流も形成される。これらの気流は、分配ガイド２３２の前方へと回り込む。 For example, as shown in FIG. 5, when the airflow F along the side surface 232c reaches the upper end of the bottom surface 232a, the flow direction is regulated by the rectifying guide 226, and the airflow I is directed downward along the bottom surface 232a. On the other hand, when the airflow H along the side surface 232e reaches the lower end of the bottom surface 232a, the flow direction is restricted by the rectifying guide 227 and is directed upward along the bottom surface 232a. Similarly, airflow along the side surface 232b and the side surface 232d is also formed. These airflows circulate in front of the distribution guide 232.
　このように、ケーシング２３１内には、分配ガイド２３２が気流を分配することによって４つの通風路が形成される。４つの通風路に沿った気流は、分配ガイド２３２の前方に回りこむ。４つの気流は、上下左右の４方向から、分配ガイド２３２と吹き出し口２３１ａとの間の領域Ｓ３（図５参照）に向かい、領域Ｓ３において互いに衝突する。衝突した空気は、吹き出し口２３１ａを通じてケーシング２３１の外部へと吹き出される。これによって、吹き出し口２３１ａから室内機２０２の前方へと向かう風Ｊが形成される。 In this way, four ventilation paths are formed in the casing 231 by the distribution guide 232 distributing the airflow. The airflow along the four ventilation paths turns around in front of the distribution guide 232. The four airflows travel from four directions, top, bottom, left, and right, to a region S3 (see FIG. 5) between the distribution guide 232 and the outlet 231a, and collide with each other in the region S3. The collided air is blown out of the casing 231 through the blowout port 231a. Thereby, the wind J which goes to the front of the indoor unit 202 from the blower outlet 231a is formed.
　以上説明したように、第２の実施形態の室内機２０２によると、ケーシング２３１内に４つの通風路が設けられ、これらの通風路を通った気流同士がケーシング２３１内で４方向から衝突する。これによって、ランダムな気流からなる風が吹き出し口２３１ａから吹き出される。したがって、室内機２０２による風は、第１の実施形態と同様に、周囲の空気と混ざりやすいものとなるため、周囲の空気との温度差が大きくなりにくい。また、幅の広い風であるため、広い範囲に風を当てることができる。 As described above, according to the indoor unit 202 of the second embodiment, four ventilation paths are provided in the casing 231, and airflows passing through these ventilation paths collide from four directions in the casing 231. Thereby, the wind which consists of random air currents blows off from the blower outlet 231a. Accordingly, the wind generated by the indoor unit 202 is likely to be mixed with the surrounding air, as in the first embodiment, and therefore, the temperature difference from the surrounding air is unlikely to increase. Further, since the wind is wide, it is possible to apply wind to a wide range.
　さらに、第２の実施形態においては、上下方向から気流を衝突させるだけでなく、左右方向も加えた４方向から気流を衝突させる。したがって、上下方向だけから気流を衝突させる場合と比べて、全体として吹き出し口２３１ａから前方に指向する風を、安定に形成することができる。 Furthermore, in the second embodiment, not only the airflow collides from the vertical direction but also the airflow collides from the four directions including the horizontal direction. Therefore, compared with the case where an airflow collides only from an up-down direction, the wind which directs ahead from the blower outlet 231a as a whole can be formed stably.
（第３の実施形態）
　図６は、本発明のさらに別の実施形態である第３の実施形態に係る室内機３０２の図である。室内機３０２は、第２の実施形態と同様、気流を分配する分配ガイドが設けられたものである。一方、室内機３０２は、ケーシングに形成された取り入れ口を通じて空気を取り入れる第１及び第２の実施形態と異なり、ダクトを通じて空気を取り入れるタイプの室内機である。 (Third embodiment)
FIG. 6 is a diagram of an indoor unit 302 according to the third embodiment which is still another embodiment of the present invention. Similar to the second embodiment, the indoor unit 302 is provided with a distribution guide for distributing the airflow. On the other hand, the indoor unit 302 is a type of indoor unit that takes in air through a duct, unlike the first and second embodiments that take in air through an intake port formed in the casing.
　室内機３０２は、本体３１０と、本体３１０の前方に配置されたガイドユニット３３０とを有している。本体３１０はケーシング３２１を有している。ケーシング３２１の背面には、通風口３２１ａが形成されている。通風口３２１ａには、後方からダクト３９９が接続されている。ケーシング３２１内には、ダクト３９９を通じて空気が取り入れられる。ケーシング３２１は前方に向かって開口している。 The indoor unit 302 has a main body 310 and a guide unit 330 disposed in front of the main body 310. The main body 310 has a casing 321. A ventilation port 321 a is formed on the back surface of the casing 321. A duct 399 is connected to the ventilation port 321a from the rear. Air is taken into the casing 321 through a duct 399. The casing 321 is open toward the front.
　ケーシング３２１内には、送風機３２４及び熱交換器３２２が収容されている。熱交換器３２２は、ケーシング３２１において前方に開口した開口部に配置されている。送風機３２４は、熱交換器３２２の後方において、上下方向に関してほぼケーシング３２１の中心に配置されている。送風機３２４は、通風口３２１ａを通じてダクト３９９から空気を流入させ、その空気を熱交換器３２２へと向かわせる。 A blower 324 and a heat exchanger 322 are accommodated in the casing 321. The heat exchanger 322 is disposed in an opening portion opened forward in the casing 321. The blower 324 is disposed at the center of the casing 321 in the vertical direction behind the heat exchanger 322. The blower 324 allows air to flow from the duct 399 through the ventilation port 321 a and directs the air to the heat exchanger 322.
　ガイドユニット３３０はケーシング３３１を有している。ケーシング３３１の背面には通風口３３１ｂが形成されている。通風口３３１ｂは、本体３１０内と連通しており、熱交換器３２２を通過した空気が通風口３３１ｂを通じてケーシング３３１内へと流入するようになっている。また、ケーシング３３１の前面には吹き出し口３３１ａが形成されている。 The guide unit 330 has a casing 331. A ventilation port 331 b is formed on the back surface of the casing 331. The ventilation port 331b communicates with the inside of the main body 310, and the air that has passed through the heat exchanger 322 flows into the casing 331 through the ventilation port 331b. In addition, a blowout port 331 a is formed on the front surface of the casing 331.
　ケーシング３３１内には分配ガイド３３２が設けられている。分配ガイド３３２は、第２の実施形態の分配ガイド２３２と同様、底面が前方に面した四角錐型の形状を有している。また、その底面は、正面視において左右方向に長尺な長方形の形状を有している。本実施形態においては、分配ガイド３３２の頂点は上下方向に関してケーシング３３１のほぼ中央に配置されている。そして、その頂点から底面の４辺に向かって延びる４つの側面が形成されている。 A distribution guide 332 is provided in the casing 331. Similar to the distribution guide 232 of the second embodiment, the distribution guide 332 has a quadrangular pyramid shape with the bottom surface facing forward. Further, the bottom surface has a rectangular shape elongated in the left-right direction when viewed from the front. In the present embodiment, the apex of the distribution guide 332 is disposed substantially at the center of the casing 331 with respect to the vertical direction. Then, four side surfaces extending from the apex toward the four sides of the bottom surface are formed.
　ケーシング３３１内には、第２の実施形態と同様の整流ガイド２２６及び２２７が設けられている。これらの構成及び配置は第２の実施形態と同様なので、説明を省略する。 In the casing 331, straightening guides 226 and 227 similar to those in the second embodiment are provided. Since these configurations and arrangements are the same as those in the second embodiment, description thereof is omitted.
　次に、室内機３０２が発生させる気流について説明する。送風機３２４が作動すると、ダクト３９９から空気が流入し、熱交換器３２２を通過する。そして、かかる気流が分配ガイド３３２に到達すると、４つの側面に沿って分配ガイド３３２の底面の４辺へと向かう４つの気流に分配される。 Next, the airflow generated by the indoor unit 302 will be described. When the blower 324 is activated, air flows from the duct 399 and passes through the heat exchanger 322. Then, when the airflow reaches the distribution guide 332, the airflow is distributed along the four side surfaces into four airflows toward the four sides of the bottom surface of the distribution guide 332.
　例えば、図６に示すように、分配ガイド３３２の頂点より上方に形成された気流Ｋは、分配ガイド３３２において斜め上方に面した側面に沿って分配ガイド３３２の底面へと向かう。そして、分配ガイド３３２より前方に到達すると、整流ガイド２２６に流れを規制され、分配ガイド３３２の前方に回り込んで下方に向かう。一方、分配ガイド３３２の頂点より下方に形成された気流Ｌは、分配ガイド３３２において斜め下方に面した側面に沿って分配ガイド３３２の底面へと向かう。そして、分配ガイド３３２より前方に到達すると、整流ガイド２２６に流れを規制され、分配ガイド３３２の前方に回り込んで上方に向かう。同様に、他の２つの側面に沿った気流も形成される。これらの気流は、分配ガイド３３２の前方へと回り込む。 For example, as shown in FIG. 6, the airflow K formed above the apex of the distribution guide 332 travels toward the bottom surface of the distribution guide 332 along the side surface of the distribution guide 332 facing obliquely upward. Then, when reaching the front of the distribution guide 332, the flow is restricted by the rectifying guide 226, and the flow is moved downward in the front of the distribution guide 332. On the other hand, the airflow L formed below the apex of the distribution guide 332 travels toward the bottom surface of the distribution guide 332 along the side surface of the distribution guide 332 that faces obliquely downward. Then, when reaching the front of the distribution guide 332, the flow is restricted by the rectifying guide 226, wraps around the front of the distribution guide 332, and moves upward. Similarly, an air flow along the other two sides is also formed. These airflows circulate in front of the distribution guide 332.
　このように、ケーシング３３１内には、第２の実施形態と同様に、４つの通風路が形成されている。４つの通風路に沿った気流は、分配ガイド３３２の前方に回りこむ。４つの気流は、上下左右の４方向から、分配ガイド３３２と吹き出し口３３１ａとの間の領域Ｓ４に向かい、この領域Ｓ４において互いに衝突する。衝突した空気は、吹き出し口３３１ａを通じてケーシング３３１の外部へと吹き出される。これによって、吹き出し口３３１ａから室内機３０２の前方へと向かう風Ｍが形成される。 As described above, four ventilation paths are formed in the casing 331 as in the second embodiment. The airflow along the four ventilation paths turns around in front of the distribution guide 332. The four air currents travel from four directions, top, bottom, left, and right, to a region S4 between the distribution guide 332 and the outlet 331a, and collide with each other in the region S4. The collided air is blown out of the casing 331 through the blowout port 331a. Thereby, the wind M which goes to the front of the indoor unit 302 from the blower outlet 331a is formed.
　以上説明したように、第３の実施形態の室内機３０２によると、第１及び第２の実施形態と同様、ランダムな気流からなる風が吹き出し口３３１ａから吹き出される。また、第２の実施形態と同様、上下左右の４方向から気流を衝突させるので、全体として吹き出し口３３１ａから前方に指向する風を、安定に形成することができる。 As described above, according to the indoor unit 302 of the third embodiment, a wind consisting of a random air current is blown out from the outlet 331a, as in the first and second embodiments. Further, as in the second embodiment, since the air currents are collided from the four directions of up, down, left, and right, the wind directed forward from the outlet 331a as a whole can be stably formed.
＜変形例＞
　以上は、本発明の好適な実施形態についての説明であるが、本発明は上述の実施形態に限られるものではなく、課題を解決するための手段に記載された範囲の限りにおいて様々な変更が可能なものである。 <Modification>
The above is a description of a preferred embodiment of the present invention, but the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope described in the means for solving the problem. It is possible.
　例えば、上述の実施形態では、ケーシングの上壁又は下壁と前壁との間に形成された角部に整流ガイドが設けられている。しかし、第２又は第３の実施形態のように、上下左右の４方向から衝突する気流を形成する場合、前壁と側壁との間に形成された角部に整流ガイドが配置されてもよい。また、整流ガイドを設けなくても、ケーシングの形状により気流を所定の方向に指向することができれば、整流ガイドを必ずしも設ける必要はない。 For example, in the above-described embodiment, the rectifying guide is provided at the corner formed between the upper wall or lower wall of the casing and the front wall. However, as in the second or third embodiment, in the case of forming an airflow that collides from four directions (up, down, left, and right), a rectifying guide may be disposed at a corner formed between the front wall and the side wall. . Even if the rectifying guide is not provided, the rectifying guide is not necessarily provided as long as the airflow can be directed in a predetermined direction due to the shape of the casing.
　また、上述の第２及び第３の実施形態では、１つの送風機のみが設けられているが、複数の送風機が設けられてもよい。例えば、第２の実施形態において、気流Ｆを安定に形成するため、分配ガイド２３２の側面２３２ｃの近傍に側面２３２ｃに沿った気流を形成する送風機を設けてもよい。 Moreover, in the above-described second and third embodiments, only one blower is provided, but a plurality of blowers may be provided. For example, in 2nd Embodiment, in order to form the airflow F stably, you may provide the air blower which forms the airflow along the side surface 232c in the vicinity of the side surface 232c of the distribution guide 232.
　また、上述の第２及び第３の実施形態では、本体側からガイドユニットに流入した気流を分配して衝突させている。しかし、ガイドユニットに空気の取り入れ口を設け、かかる取り入れ口から取り入れた空気による気流と分配した気流とを衝突させてもよい。これによると、第１の実施形態と同様、適度な温度の気流を吹き出すことができる。 In the second and third embodiments described above, the airflow that has flowed into the guide unit from the main body side is distributed and collided. However, an air intake port may be provided in the guide unit, and the airflow from the air taken in from the intake port may collide with the distributed airflow. According to this, the airflow of moderate temperature can be blown out similarly to 1st Embodiment.
　また、上述の実施形態では冷風を形成する場合を想定しているが、温風を形成する場合に本発明を適用してもよい。 Moreover, although the case where cold air is formed is assumed in the above-described embodiment, the present invention may be applied when hot air is formed.
　本発明を利用すれば、風を当てた物体を局所的に冷やし過ぎたり暖めすぎたりすることが防止される。 If the present invention is used, it is possible to prevent the object to which the wind is applied from being overcooled or overheated locally.
