室外機Outdoor unit
　本開示は、室外機に関する。 The present disclosure relates to an outdoor unit.
　例えば、特許文献１には、熱交換器と、熱交換器を収容する筐体とを備える室外機が開示されている。室外機の筐体には、外気の温度を測定するためのサーミスタを保持する保持部が設けられている。サーミスタは、室外機の筐体内部における結露発生を防ぐための室外機の運転制御に利用される。特許文献１において、保持部は、筐体の側面を構成する外郭部品（側板部）と別個に形成された手掛部品に形成されている。手掛部品は外郭部品に組付けられる。 For example, Patent Document 1 discloses an outdoor unit that includes a heat exchanger and a casing that houses the heat exchanger. The housing of the outdoor unit is provided with a holding part that holds a thermistor for measuring the temperature of outside air. The thermistor is used to control the operation of the outdoor unit to prevent condensation from forming inside the casing of the outdoor unit. In Patent Document 1, the holding part is formed in a handhold part that is formed separately from an outer part (side plate part) that constitutes the side surface of the casing. The hand parts are assembled to the outer shell parts.

　図２および図３に示す熱交換器３は、熱交換器３の内部に流れる冷媒と、熱交換器３を通過する空気との間で熱交換を行う。熱交換器３は、例えば蒸発器または凝縮器として機能する。
　本実施の形態において、熱交換器３は、後側板部２２Ｂおよび右側板部２２Ｄに沿う板状に形成されている。後側板部２２Ｂに沿う熱交換器３の部位の一部は、後側板部２２Ｂの吐出口２２２を通して筐体２の後側に露出する。右側板部２２Ｄに沿う熱交換器３の部位の一部は、右側板部２２Ｄの通気口２２３，２２５を通して筐体２の右側に露出する。熱交換器３は、上下方向Ｚに見て後側板部２２Ｂと右側板部２２Ｄとの角部において９０度湾曲する湾曲部３１を有する。 The heat exchanger 3 shown in FIGS. 2 and 3 performs heat exchange between the refrigerant flowing inside the heat exchanger 3 and the air passing through the heat exchanger 3. Heat exchanger 3 functions, for example, as an evaporator or a condenser.
In this embodiment, the heat exchanger 3 is formed in a plate shape along the rear side plate part 22B and the right side plate part 22D.

　図７は、側板部２２の要部を示す斜視図であって、側板部に形成された後述の保持部２５にサーミスタ７を保持させた状態を示す斜視図である。
　図３、図６および図７に示すように、室外機１は、筐体２に設けられるサーミスタ７を備える。本実施の形態のサーミスタ７は、軸方向の寸法が径方向の寸法よりも大きい細長い円柱状の外観を有する。なお、サーミスタ７の外観はこれに限られず、任意であってよい。
　サーミスタ７は、外気の温度を測定する。サーミスタ７は、当該サーミスタ７から延びるリード線７１（電気配線）によって前述の電気品ボックス６に接続されている。サーミスタ７は、筐体２の内部に結露が発生したり、当該結露が凍ったりすることを防ぐことを目的とした室外機１の動作の制御に利用される。 FIG. 7 is a perspective view showing a main part of the side plate part 22, and is a perspective view showing a state in which the thermistor 7 is held in a holding part 25, which will be described later, formed in the side plate part.
As shown in FIGS. 3, 6, and 7, the outdoor unit 1 includes a thermistor 7 provided in the housing 2. The thermistor 7 of this embodiment has an elongated cylindrical appearance in which the axial dimension is larger than the radial dimension. Note that the appearance of the thermistor 7 is not limited to this, and may be arbitrary.
Thermistor 7 measures the temperature of the outside air. The thermistor 7 is connected to the electrical component box 6 described above by a lead wire 71 (electrical wiring) extending from the thermistor 7. The thermistor 7 is used to control the operation of the outdoor unit 1 in order to prevent condensation from forming inside the housing 2 and from freezing the condensation.
　この点について説明すれば、室外機１が暖房運転している際には、筐体２の内部が暖かくなり、冷たい外気との温度差が大きくなることで、熱交換器３などを含む筐体２の内部に結露が発生したり、当該結露が凍ってしまったりすることがある。これに対し、室外機１では、外気が予め定められた温度条件下となったことをサーミスタ７が検知した際に、電気品ボックス６が室外機１の動作を制御して、一時的に暖房運転から冷房運転に切り換える。これにより、筐体２の内部における結露の発生が抑制される。 To explain this point, when the outdoor unit 1 is in heating operation, the inside of the casing 2 becomes warm, and the temperature difference between it and the cold outside air becomes large, causing the casing including the heat exchanger 3, etc. Condensation may occur inside the device, or the condensation may freeze. On the other hand, in the outdoor unit 1, when the thermistor 7 detects that the outside air has reached a predetermined temperature condition, the electrical box 6 controls the operation of the outdoor unit 1 to temporarily heat the air. Switch from driving to cooling operation. This suppresses the occurrence of dew condensation inside the housing 2.

　図５から図９に示すように、室外機１は、前述したサーミスタ７を保持する保持部２５を有する。保持部２５は、側板部２２に一体に成形されている。本実施の形態において、保持部２５は、樹脂成形によって側板部２２の右側板部２２Ｄに一体に成形されている。 FIG. 8 is a diagram schematically showing the holding part 25 provided in the outdoor unit 1. FIG. 9 is a cross-sectional view showing essential parts of the outdoor unit 1, and is a cross-sectional view taken along the line IX--IX in FIG.
As shown in FIGS. 5 to 9, the outdoor unit 1 includes a holding portion 25 that holds the thermistor 7 described above. The holding portion 25 is integrally formed with the side plate portion 22. In this embodiment, the holding portion 25 is integrally molded with the right side plate portion 22D of the side plate portion 22 by resin molding.
　右側板部２２Ｄにおける保持部２５の位置は、任意であってよい。本実施形態において、保持部２５は右側板部２２Ｄの上部に位置する。また、保持部２５は、右側板部２２Ｄの上部のうち後側板部２２Ｂに近い後端部に位置する。また、保持部２５は、右側板部２２Ｄの内側（－Ｙ側）に配置されている。そして、保持部２５は、熱交換器３の上部に対して熱交換器３の右側（＋Ｙ側）に隣り合わせて位置する。このため、保持部２５に保持されるサーミスタ７は、右側板部２２Ｄの上部かつ後端部に位置する。また、当該サーミスタ７は、熱交換器３の上部に対して熱交換器３の右側（＋Ｙ側）に隣り合わせて位置する。 The position of the holding part 25 on the right side plate part 22D may be arbitrary. In this embodiment, the holding part 25 is located at the upper part of the right side plate part 22D. Further, the holding portion 25 is located at the rear end portion of the upper portion of the right side plate portion 22D near the rear side plate portion 22B. Further, the holding portion 25 is arranged inside (−Y side) of the right side plate portion 22D. The holding part 25 is located adjacent to the right side (+Y side) of the heat exchanger 3 with respect to the upper part of the heat exchanger 3. Therefore, the thermistor 7 held by the holding part 25 is located at the upper and rear end of the right side plate part 22D. Further, the thermistor 7 is located adjacent to the right side (+Y side) of the heat exchanger 3 with respect to the upper part of the heat exchanger 3.
　図９に示すように、保持部２５は、水平方向において右側板部２２Ｄの内側から外側に向うにしたがって下方に傾斜する方向にサーミスタ７が挿入されるように構成されている。言い換えれば、保持部２５は、熱交換器３の外側において、下方（－Ｚ方）に向うにしたがって水平方向において熱交換器３から離れる方向にサーミスタ７が挿入されるように構成されている。 As shown in FIG. 9, the holding portion 25 is configured such that the thermistor 7 is inserted in a direction that is inclined downward from the inside to the outside of the right side plate portion 22D in the horizontal direction. In other words, the holding part 25 is configured so that the thermistor 7 is inserted in the direction away from the heat exchanger 3 in the horizontal direction as it goes downward (-Z direction) on the outside of the heat exchanger 3.
　具体的に、保持部２５は、右側板部２２Ｄの内側において右側（＋Ｙ側）に向うにしたがって下方（－Ｚ方）に傾斜する方向にサーミスタ７が挿入されるように形成されている。本実施の形態において、水平方向の一つである左右方向Ｙに対するサーミスタ７の挿入方向の傾斜角度θは４５度となっているが、これに限ることはない。本実施の形態において、保持部２５は、細長い円柱状に形成されたサーミスタ７を、その軸方向に挿入するように形成されている。 Specifically, the holding part 25 is formed so that the thermistor 7 is inserted in a direction that is inclined downward (-Z direction) toward the right side (+Y side) inside the right side plate part 22D. In this embodiment, the inclination angle θ of the insertion direction of the thermistor 7 with respect to the left-right direction Y, which is one of the horizontal directions, is 45 degrees, but it is not limited to this. In this embodiment, the holding part 25 is formed so that the thermistor 7 formed in an elongated columnar shape is inserted in the axial direction thereof.
　図３、図６および図９に示すように、保持部２５に挿入されたサーミスタ７に対し、リード線７１は、サーミスタ７の挿入方向の後側から電気品ボックス６に向けて延びる。リード線７１は、サーミスタ７からその挿入方向と逆向きに延びている。リード線７１は、湾曲可能となっている。 As shown in FIGS. 3, 6, and 9, with respect to the thermistor 7 inserted into the holding portion 25, the lead wire 71 extends toward the electrical component box 6 from the rear side in the insertion direction of the thermistor 7. The lead wire 71 extends from the thermistor 7 in a direction opposite to its insertion direction. The lead wire 71 is bendable.
　図５および図８に示すように、本実施の形態の保持部２５は、サーミスタ７を挟む爪部２５１を有する。爪部２５１は、右側板部２２Ｄに対して弾性的に撓み変形可能に形成されている。爪部２５１は、弾性的に撓み変形することでその弾性力によってサーミスタ７を挟んで保持する。爪部２５１が弾性的に撓み変形する方向は、爪部２５１がサーミスタ７を挟む方向に対応している。本実施の形態において、爪部２５１がサーミスタ７を挟む方向は、保持部２５に対するサーミスタ７の挿入方向に直交する方向である。 As shown in FIGS. 5 and 8, the holding portion 25 of this embodiment has claw portions 251 that sandwich the thermistor 7. The claw portion 251 is formed to be elastically deformable relative to the right side plate portion 22D. The claw portions 251 are elastically deformed to sandwich and hold the thermistor 7 by their elastic force. The direction in which the claw portions 251 are elastically deformed corresponds to the direction in which the claw portions 251 sandwich the thermistor 7 . In this embodiment, the direction in which the claw portions 251 sandwich the thermistor 7 is a direction perpendicular to the direction in which the thermistor 7 is inserted into the holding portion 25 .
　爪部２５１の数は、例えば１つでもよいが、本実施の形態では２つである。２つの爪部２５１は、これらの配列方向に弾性的に撓み変形可能である。サーミスタ７の外面に接触する爪部２５１の面は、サーミスタ７に面接触するようにサーミスタ７の外面の形状に対応している。２つの爪部２５１の間隔は、これら２つの爪部２５１の間に挿入されるサーミスタ７の部位の寸法よりも小さい。これにより、サーミスタ７を２つの爪部２５１の間に挿入した状態では、爪部２５１が弾性的に撓み変形する。そして、弾性的に撓み変形した爪部２５１の弾性力によってサーミスタ７が保持される。 The number of claw portions 251 may be one, for example, but is two in this embodiment. The two claw portions 251 can be elastically deformed in the direction in which they are arranged. The surface of the claw portion 251 that contacts the outer surface of the thermistor 7 corresponds to the shape of the outer surface of the thermistor 7 so as to make surface contact with the thermistor 7. The distance between the two claw parts 251 is smaller than the size of the part of the thermistor 7 inserted between these two claw parts 251. As a result, when the thermistor 7 is inserted between the two claws 251, the claws 251 are elastically deformed. The thermistor 7 is held by the elastic force of the claw portion 251 that is elastically deformed.
　図５、図７及び図９に示すように、右側板部２２Ｄには、保持部２５に挿入されたサーミスタ７を下側（－Ｚ側）から支持する支持部２６が一体に成形されている。支持部２６は、保持部２５の下側に位置する。支持部２６には、保持部２５に挿入されたサーミスタ７の挿入方向の先端部が接触する。本実施の形態の支持部２６は、前述した右側板部２２Ｄの手掛部２２４によって構成されている。このため、手掛部２２４の通気口２２５は、保持部２５に挿入されたサーミスタ７の近くに位置する。 As shown in FIGS. 5, 7, and 9, a support section 26 that supports the thermistor 7 inserted into the holding section 25 from below (-Z side) is integrally formed on the right side plate section 22D. . The support part 26 is located below the holding part 25. The tip of the thermistor 7 inserted into the holding portion 25 in the insertion direction comes into contact with the support portion 26 . The support portion 26 of this embodiment is constituted by the handle portion 224 of the above-mentioned right side plate portion 22D. Therefore, the vent 225 of the handhold part 224 is located near the thermistor 7 inserted into the holding part 25.
　本実施の形態によれば、サーミスタ７を保持する保持部２５が、筐体２の右側板部２２Ｄに一体に成形されている。このため、サーミスタ７を筐体２に取り付けるための室外機１の部品点数を削減することができる。これにより、室外機１の組立工数を減らして、組立作業性の向上を図ることができる。 According to this embodiment, the holding portion 25 that holds the thermistor 7 is integrally formed on the right side plate portion 22D of the housing 2. Therefore, the number of parts of the outdoor unit 1 for attaching the thermistor 7 to the housing 2 can be reduced. Thereby, the number of man-hours required to assemble the outdoor unit 1 can be reduced, and the assembling workability can be improved.
　また、保持部２５が右側板部２２Ｄに一体に成形されていることで、右側板部２２Ｄに対するサーミスタ７の位置の誤差を小さく抑えることができる。すなわち、サーミスタ７の正確な位置決めを容易に行うことができる。これにより、結露発生を防ぐための室外機１の運転制御をより確実に正しく実施することが可能となる。 Furthermore, since the holding part 25 is integrally formed with the right side plate part 22D, the error in the position of the thermistor 7 with respect to the right side plate part 22D can be suppressed to a small value. That is, accurate positioning of the thermistor 7 can be easily performed. This makes it possible to more reliably and correctly control the operation of the outdoor unit 1 to prevent the occurrence of dew condensation.
　また、本実施の形態によれば、保持部２５は、水平方向において右側板部２２Ｄの内側から外側に向うにしたがって下方に傾斜する方向にサーミスタ７が挿入されるように構成されている。このため、サーミスタ７の挿入方向の後側から延びるリード線７１が筐体２の天板部２３に干渉することを抑制しながら、リード線７１にかかる負荷を軽減することができる。以下、この点について、説明する。 Furthermore, according to the present embodiment, the holding portion 25 is configured such that the thermistor 7 is inserted in a direction that is inclined downward from the inside to the outside of the right side plate portion 22D in the horizontal direction. Therefore, the load on the lead wire 71 can be reduced while preventing the lead wire 71 extending from the rear side in the insertion direction of the thermistor 7 from interfering with the top plate portion 23 of the housing 2. This point will be explained below.
　図９に示すように、リード線７１は、サーミスタ７の後側からサーミスタ７の挿入方向と逆向きに延びる。このため、サーミスタ７の挿入方向が下方（－Ｚ方）である場合には、リード線７１がサーミスタ７から上方（＋Ｚ方）に延びるため、筐体２の天板部２３に干渉してしまう。また、リード線７１と天板部２３との干渉を回避するためには、リード線７１を湾曲させる角度が例えば９０度と大きくする必要がある。この場合、リード線７１にかかる負荷が大きくなってしまう。
　これに対し、サーミスタ７の挿入方向が上下方向Ｚに対して傾斜する場合には、リード線７１が筐体２の天板部２３に干渉することを抑制できる。また、リード線７１と天板部２３との干渉を回避するために、リード線７１を曲げる角度を小さく抑えることができる。したがって、リード線７１にかかる負荷を軽減することができる。 As shown in FIG. 9, the lead wire 71 extends from the rear side of the thermistor 7 in a direction opposite to the direction in which the thermistor 7 is inserted. Therefore, when the insertion direction of the thermistor 7 is downward (-Z direction), the lead wire 71 extends upward (+Z direction) from the thermistor 7 and interferes with the top plate part 23 of the housing 2. . Further, in order to avoid interference between the lead wire 71 and the top plate portion 23, the angle at which the lead wire 71 is bent needs to be as large as, for example, 90 degrees. In this case, the load applied to the lead wire 71 becomes large.
On the other hand, when the insertion direction of the thermistor 7 is inclined with respect to the vertical direction Z, it is possible to suppress the lead wire 71 from interfering with the top plate portion 23 of the housing 2 . Further, in order to avoid interference between the lead wire 71 and the top plate portion 23, the angle at which the lead wire 71 is bent can be kept small. Therefore, the load on the lead wire 71 can be reduced.
　また、保持部２５に対するサーミスタ７の挿入方向が、水平方向において右側板部２２Ｄの内側から外側に向うにしたがって下方に傾斜する方向となっていることで、水平方向において熱交換器３が保持部２５の近くに配置されていても、保持部２５に対するサーミスタ７の挿入が熱交換器３によって阻害されることを抑制できる。以下、この点について説明する。 Furthermore, the insertion direction of the thermistor 7 into the holding part 25 is a direction that is inclined downward from the inside to the outside of the right side plate part 22D in the horizontal direction, so that the heat exchanger 3 can be inserted into the holding part in the horizontal direction. Even if the thermistor 7 is disposed near the holding portion 25 , insertion of the thermistor 7 into the holding portion 25 can be prevented from being obstructed by the heat exchanger 3 . This point will be explained below.
　保持部２５が水平方向において右側板部２２Ｄの内側と熱交換器３との間に位置し、水平方向において保持部２５が熱交換器３の近くに位置する場合、サーミスタ７を、保持部２５に対して右側板部２２Ｄの内側から外側に水平方向に挿入することは難しい。これに対し、図９に示すように、サーミスタ７の挿入方向が水平方向に対して上方（＋Ｚ方）に傾斜している場合、保持部２５に対するサーミスタ７の挿入が熱交換器３によって阻害されることを抑制できる。 When the holding part 25 is located between the inside of the right side plate part 22D and the heat exchanger 3 in the horizontal direction, and the holding part 25 is located near the heat exchanger 3 in the horizontal direction, the thermistor 7 is On the other hand, it is difficult to horizontally insert the right side plate portion 22D from the inside to the outside. On the other hand, as shown in FIG. 9, when the insertion direction of the thermistor 7 is inclined upward (+Z direction) with respect to the horizontal direction, the insertion of the thermistor 7 into the holding part 25 is inhibited by the heat exchanger 3. This can be suppressed.
　また、本実施の形態によれば、保持部２５に挿入されたサーミスタ７を下側から支持する支持部２６によって、サーミスタ７の挿入方向におけるサーミスタ７の位置決めを行うことができる。そして、支持部２６は、保持部２５と同様に右側板部２２Ｄに一体に成形されている。これにより、サーミスタ７の挿入方向におけるサーミスタ７の位置に誤差が生じることを効果的に抑制できる。したがって、サーミスタ７の正確な位置決めを容易に行うことができる。 Furthermore, according to the present embodiment, the thermistor 7 can be positioned in the insertion direction of the thermistor 7 by the support part 26 that supports the thermistor 7 inserted into the holding part 25 from below. The support portion 26, like the holding portion 25, is integrally formed with the right side plate portion 22D. Thereby, it is possible to effectively suppress errors in the position of the thermistor 7 in the insertion direction of the thermistor 7. Therefore, accurate positioning of the thermistor 7 can be easily performed.
　また、本実施の形態によれば、上記の支持部２６が、右側板部２２Ｄの外側から窪んで形成された手掛部２２４によって構成されている。すなわち、支持部２６が手掛部２２４を兼用している。これにより、支持部２６が手掛部２２４と別に構成される場合と比較して、右側板部２２Ｄの形状の単純化を図ることができる。 Further, according to the present embodiment, the above-mentioned support portion 26 is constituted by a handhold portion 224 that is recessed from the outside of the right side plate portion 22D. That is, the support portion 26 also serves as the handhold portion 224. Thereby, the shape of the right side plate portion 22D can be simplified compared to the case where the support portion 26 is configured separately from the handhold portion 224.
　また、本実施の形態によれば、支持部２６をなす手掛部２２４に通気口２２５が形成されている。また、右側板部２２Ｄに通気口２２３が形成されている。これら通気口２２３，２２５を通して外気を筐体２の内側に引き込むことができる。そして、手掛部２２４の通気口２２５は、当該手掛部２２４によって支持されるサーミスタ７の近くに位置する。このため、保持部２５によって保持されたサーミスタ７が筐体２の内側に位置していても、外気の温度をサーミスタ７によってより正確に測定することができる。 Furthermore, according to the present embodiment, a vent hole 225 is formed in the handhold portion 224 forming the support portion 26. Further, a vent hole 223 is formed in the right side plate portion 22D. Outside air can be drawn into the housing 2 through these vents 223 and 225. The vent 225 of the handhold portion 224 is located near the thermistor 7 supported by the handhold portion 224 . Therefore, even if the thermistor 7 held by the holding part 25 is located inside the housing 2, the temperature of the outside air can be measured more accurately by the thermistor 7.
　また、本実施の形態によれば、保持部２５がサーミスタ７を挟む爪部２５１を有する。このため、弾性的に撓み変形した爪部２５１の弾性力によってサーミスタ７を安定に保持することができる。 Furthermore, according to the present embodiment, the holding portion 25 has the claw portions 251 that sandwich the thermistor 7. Therefore, the thermistor 7 can be stably held by the elastic force of the elastically deformed claw portions 251.
