室外機１０は、空気調和機及び給湯器等の装置の室外機である。図１に示すように、室外機１０は、筐体１１と、保護カバー１２とを備える。Embodiment 1 FIG.
*** Explanation of configuration ***
The configuration of the outdoor unit 10 according to Embodiment 1 will be described based on FIGS. 1 to 5.
The outdoor unit 10 is an outdoor unit for devices such as an air conditioner and a water heater. As shown in FIG. 1, the outdoor unit 10 includes a housing 11 and a protective cover 12.

筐体１１は、内部に圧縮機等の冷凍サイクルを構成する機械と、機械を制御する電気部品とが収納されている。
筐体１１は、冷凍サイクルを構成する冷媒配管の接続口である接続バルブ１３と、電気部品の接続口であり、配線２９が接続される端子台開口部１４とが外部に露出して設けられている。接続バルブ１３と端子台開口部１４とは、筐体１１の同じ側面に設けられており、接続バルブ１３が下方に設けられ、端子台開口部１４が上方に設けられている。The housing 11 houses therein a machine that constitutes a refrigeration cycle such as a compressor, and electrical components that control the machine.
The housing 11 is provided with a connection valve 13 that is a connection port of a refrigerant pipe constituting a refrigeration cycle and a terminal block opening 14 that is a connection port of an electrical component and to which a wiring 29 is connected exposed to the outside. ing. The connection valve 13 and the terminal block opening 14 are provided on the same side surface of the housing 11, the connection valve 13 is provided on the lower side, and the terminal block opening 14 is provided on the upper side.

保護カバー１２は、接続バルブ１３と端子台開口部１４との両方を覆うように筐体１１に取り付けられる。保護カバー１２は、下方に設けられたフック１５が筐体１１の取付孔１６に挿入され、上方に設けられた通し孔１７にネジが通され筐体１１のネジ穴１８に挿入されて、合計４か所で筐体１１に取り付けられる。保護カバー１２は、筐体１１に取り付けられると、周縁部分が筐体１１に密着し、他の部分には筐体１１との間に空間ができる。
保護カバー１２は、接続バルブ１３を覆うバルブカバー部分１９と端子台開口部１４を覆う電気カバー部分２０との間の連通部分２１に、筐体１１との間の空間が狭くなるように筐体１１の方に凹んだ凹部２２が形成されている。凹部２２は、底２３が筐体１１の側面と平行な平面になっている。
保護カバー１２は、電気カバー部分２０に、電気部品が発する熱を放出するために格子状に開けられた放熱孔２４が設けられている。The protective cover 12 is attached to the housing 11 so as to cover both the connection valve 13 and the terminal block opening 14. The protective cover 12 has a hook 15 provided at the lower side inserted into the mounting hole 16 of the housing 11, a screw is passed through the through hole 17 provided at the upper side, and inserted into the screw hole 18 of the housing 11. It is attached to the housing 11 at four places. When the protective cover 12 is attached to the housing 11, the peripheral portion is in close contact with the housing 11, and a space is formed between the protective cover 12 and the housing 11.
The protective cover 12 is provided in a housing so that a space between the housing 11 and the communication cover 21 between the valve cover portion 19 that covers the connection valve 13 and the electric cover portion 20 that covers the terminal block opening 14 is narrowed. 11 is formed with a recess 22 that is recessed toward 11. The recess 22 has a flat surface whose bottom 23 is parallel to the side surface of the housing 11.
The protective cover 12 is provided with heat radiating holes 24 formed in a lattice shape in the electric cover portion 20 in order to release heat generated by the electric components.

図２及び図３に示すように、保護カバー１２は、凹部２２よりもバルブカバー部分１９寄りに引込孔２５が形成されている。引込孔２５は、接続バルブ１３に接続される配管と、端子台開口部１４に接続される配線２９とを引き込むためのものである。   As shown in FIGS. 2 and 3, the protective cover 12 is formed with a drawing hole 25 closer to the valve cover part 19 than the recess 22. The drawing hole 25 is for drawing in the pipe connected to the connection valve 13 and the wiring 29 connected to the terminal block opening 14.

図２及び図４及び図５に示すように、室外機１０は隙間材２６を備える。図２及び図４及び図５では、保護カバー１２と区別するため、隙間材２６にハッチングを入れて示している。
隙間材２６は、緩衝材として用いられるような弾力性のある材料で形成されている。隙間材２６は、保護カバー１２における凹部２２の底２３に設置される。隙間材２６が設置された状態で保護カバー１２が筐体１１に取り付けられる。そして、隙間材２６は、凹部２２の底２３と筐体１１の側面との間の空間を埋めて連通部分２１を塞ぐ。As shown in FIGS. 2, 4, and 5, the outdoor unit 10 includes a gap member 26. In FIGS. 2, 4, and 5, the gap material 26 is hatched to be distinguished from the protective cover 12.
The gap material 26 is formed of an elastic material that is used as a cushioning material. The gap member 26 is installed on the bottom 23 of the recess 22 in the protective cover 12. The protective cover 12 is attached to the housing 11 with the gap material 26 installed. The gap member 26 fills the space between the bottom 23 of the recess 22 and the side surface of the housing 11 and closes the communication portion 21.

図５に示すように、隙間材２６は、筐体１１と凹部２２の底２３との間の幅Ｗよりも若干厚みがある。隙間材２６は、保護カバー１２が筐体１１に取り付けられると、筐体１１と凹部２２の底２３との間で押しつぶされて設けられる。隙間材２６は、押しつぶされているため、筐体１１の側面と、凹部２２の底２３とに密着し、筐体１１と保護カバー１２との間をほとんど隙間なく塞ぐ。
なお、引込孔２５から引き込まれた配線２９が連通部分２１を通って端子台開口部１４に接続される。そのため、筐体１１と隙間材２６との間に、配線２９が挟まれる。しかし、隙間材２６は、弾力性があるため、配線２９を傷つけることなく、筐体１１と保護カバー１２との間をほとんど隙間なく塞ぐ。As shown in FIG. 5, the gap member 26 is slightly thicker than the width W between the housing 11 and the bottom 23 of the recess 22. When the protective cover 12 is attached to the housing 11, the gap material 26 is provided by being crushed between the housing 11 and the bottom 23 of the recess 22. Since the gap member 26 is crushed, the gap member 26 is in close contact with the side surface of the casing 11 and the bottom 23 of the recess 22 and closes the gap between the casing 11 and the protective cover 12 with almost no gap.
In addition, the wiring 29 drawn from the drawing hole 25 is connected to the terminal block opening 14 through the communication portion 21. Therefore, the wiring 29 is sandwiched between the housing 11 and the gap material 26. However, since the gap member 26 is elastic, it closes the space between the housing 11 and the protective cover 12 almost without gaps without damaging the wiring 29.

図２及び図４に示すように、保護カバー１２には、底２３の下の左右両側に、一対の突起２７を有する。隙間材２６は、凸部分を有する形状であり、凸部分を下にして、凸部分が突起２７の間に入れられて凹部２２の底２３に設置される。これにより、保護カバー１２が筐体１１に取り付けられる際、隙間材２６が下にずれることが防止される。   As shown in FIGS. 2 and 4, the protective cover 12 has a pair of protrusions 27 on both the left and right sides under the bottom 23. The gap material 26 has a shape having a convex portion, and the convex portion is placed between the protrusions 27 with the convex portion facing down, and is installed on the bottom 23 of the concave portion 22. Thereby, when the protective cover 12 is attached to the housing | casing 11, it is prevented that the clearance gap material 26 slips down.

図１及び図３及び図５に示すように、凹部２２は、上側の面２８が底２３から凹部２２の開口に向かって上方向に傾斜している。ここでは、上側の面２８は、図５に示す角度θが１３５度以上の角度となるように傾斜している。   As shown in FIGS. 1, 3, and 5, the recess 22 has an upper surface 28 inclined upward from the bottom 23 toward the opening of the recess 22. Here, the upper surface 28 is inclined so that the angle θ shown in FIG. 5 is an angle of 135 degrees or more.

＊＊＊効果の説明＊＊＊
以上のように、実施の形態１に係る室外機１０は、隙間材２６によりバルブカバー部分１９と電気カバー部分２０との間の連通部分２１を塞いでいる。これにより、引込孔２５から侵入した生物が端子台開口部１４の付近に行くことができない。そのため、小動物により電気部品が短絡することを防止できる。*** Explanation of effects ***
As described above, the outdoor unit 10 according to the first embodiment closes the communication portion 21 between the valve cover portion 19 and the electric cover portion 20 with the gap member 26. Thereby, the living thing which invaded from the drawing hole 25 cannot go to the vicinity of the terminal block opening part 14. Therefore, it is possible to prevent an electrical component from being short-circuited by a small animal.

特に、実施の形態１に係る室外機１０は、凹部２２の底２３が平面になっている。これにより、隙間材２６を筐体１１と凹部２２の底２３とにしっかりと密着させることが可能である。そのため、連通部分２１をほとんど隙間なく塞ぐことができる。   In particular, in the outdoor unit 10 according to the first embodiment, the bottom 23 of the recess 22 is flat. As a result, the gap member 26 can be firmly attached to the housing 11 and the bottom 23 of the recess 22. Therefore, it is possible to close the communication portion 21 with almost no gap.

実施の形態１に係る室外機１０は、凹部２２が放熱孔２４よりも下側に設けられている。これにより、凹部２２と隙間材２６とが、電気部品から出た熱が放熱孔２４から放出されることを妨げない。   In the outdoor unit 10 according to Embodiment 1, the recess 22 is provided below the heat radiation hole 24. Thereby, the recess 22 and the gap member 26 do not prevent the heat generated from the electrical component from being released from the heat radiation hole 24.

実施の形態１に係る室外機１０は、凹部２２の上側の面２８が底２３から開口に向かって上方向に傾斜している。これにより、凹部２２に手を掛けづらくなり、作業員によって凹部２２が取手として利用されることを防止できる。   In the outdoor unit 10 according to Embodiment 1, the upper surface 28 of the recess 22 is inclined upward from the bottom 23 toward the opening. This makes it difficult to place a hand on the recess 22 and prevents the operator from using the recess 22 as a handle.

なお、凹部２２を大きく凹ませ、底２３が筐体１１に当接するようにすることも可能である。しかし、このようにしてしまうと、底２３により配線２９が押しつぶされてしまい、配線２９が傷ついてしまう恐れがある。   Note that the concave portion 22 can be greatly recessed so that the bottom 23 comes into contact with the housing 11. However, if this is done, the wiring 29 may be crushed by the bottom 23 and the wiring 29 may be damaged.
