Embodiment 1 FIG.
1 is an exploded perspective view of an outdoor unit of an air conditioner according to Embodiment 1 of the present invention, and FIG. 2 is a cross-sectional view of a main part of FIG.
In the figure, a main body outline 1 of an outdoor unit of an air conditioner is made of a metal plate, and a base 2 is arranged at the lower part. A machine room 1a containing a compressor, refrigerant piping, electrical equipment, and the like is provided inside the main body shell 1 and is partitioned from the air path by a metal separator 1b. The machine room 1a also includes a soundproof material that easily spreads when ignited, processing residual oil, and the like (not shown).

室外ユニットの本体外郭1の側面には、絞り加工などによって形成したポケット3a,3bを両側に備えた金属製のバルブベッド3が固定され、その中央部付近には冷媒バルブが取り付けられる座面4が設けられている。
バックパネル5には、バルブベッド3の位置に対応してほぼ逆U字状に開口した下方開口部5aが設けられ、さらに開口部5aの両側にはバルベッド3のポケット3a,3bの位置に対応して、係止孔5b,5cが設けられ、これらの上部には電線接続のための電気品開口部5dを有し、下方開口部5aと電気品開口部5dとの間にはネジ孔5eが設けられている。
A metal valve bed 3 having pockets 3a and 3b formed by drawing or the like on both sides is fixed to the side surface of the main body outer shell 1 of the outdoor unit, and a seating surface 4 on which a refrigerant valve is attached near the center. Is provided.
The back panel 5 is provided with a lower opening 5a that opens in a substantially inverted U shape corresponding to the position of the valve bed 3, and further corresponds to the positions of the pockets 3a and 3b of the valve bed 3 on both sides of the opening 5a. Then, the locking holes 5b and 5c are provided, and an upper part thereof has an electrical product opening 5d for connecting an electric wire, and a screw hole 5e between the lower opening 5a and the electrical product opening 5d. Is provided.

樹脂製サービスパネル6の両側には、バックパネル5の両側に設けた係止孔5b,5cの位置に対応した係止ツメ6a,6bが設けられている。また、樹脂製サービスパネル6には、バックパネル5のネジ孔5eの位置に対応し、ネジ挿通孔6cが設けられており、ネジ挿通孔6cからネジ孔5eに固定ネジ7を螺入するようにしてある。
こうして、バルブベッド3やバックパネル5は、他の外郭部品とともにネジ止めなどによって本体外郭1に固定され、外郭の一部を構成している。そして、バルブベッド3の外側に、バックパネル5が覆い被さるようにして取り付けられており、電気品開口部5dと冷媒バルブとは、樹脂製サービスパネル6によって外側より塞がれている。
Locking claws 6a, 6b corresponding to the positions of the locking holes 5b, 5c provided on both sides of the back panel 5 are provided on both sides of the resin service panel 6. The resin service panel 6 is provided with a screw insertion hole 6c corresponding to the position of the screw hole 5e of the back panel 5, and the fixing screw 7 is screwed into the screw hole 5e from the screw insertion hole 6c. It is.
Thus, the valve bed 3 and the back panel 5 are fixed to the outer shell 1 together with other outer parts by screws or the like, and constitute a part of the outer shell. The back panel 5 is attached to the outside of the valve bed 3 so as to cover it, and the electrical component opening 5d and the refrigerant valve are closed from the outside by the resin service panel 6.

次に、樹脂製サービスパネル6の組み立ての手順を説明する。まず、バルブベッド3やバックパネル5を、他の外郭部品とともにネジ止めによって本体外郭1に固定する。次に、樹脂製サービスパネル6の係止ツメ6a,6bをバックパネル5の係止孔5b,5cに挿入したのち、樹脂製サービスパネル6を上方にずらし、バックパネル5と樹脂製サービスパネル6を接合状態にし、そののち、固定ネジ7を樹脂製サービスパネル6のネジ挿通孔6c、バックパネル5のネジ孔5eに螺入する。こうすると、樹脂製サービスパネル6はバックパネル5に固定されるとともに、樹脂製サービスパネル6の係止ツメ6a,6bは、バックパネル5の係止孔5b,5cを貫通してバルブベッド3のポケット3a,3b内に収容され、バルブベッド3のポケット3a,3bにより全周にわたり覆われる。   Next, a procedure for assembling the resin service panel 6 will be described. First, the valve bed 3 and the back panel 5 are fixed to the main body outline 1 by screwing together with other outline parts. Next, after inserting the locking claws 6 a and 6 b of the resin service panel 6 into the locking holes 5 b and 5 c of the back panel 5, the resin service panel 6 is shifted upward, and the back panel 5 and the resin service panel 6 are moved. After that, the fixing screw 7 is screwed into the screw insertion hole 6 c of the resin service panel 6 and the screw hole 5 e of the back panel 5. Thus, the resin service panel 6 is fixed to the back panel 5, and the locking claws 6 a and 6 b of the resin service panel 6 pass through the locking holes 5 b and 5 c of the back panel 5 and the valve bed 3. It is accommodated in the pockets 3a and 3b, and is covered all around by the pockets 3a and 3b of the valve bed 3.

次に、樹脂製サービスパネル6に着火された場合の動作を説明する。樹脂製サービスパネル6に着火されると、延焼した炎は機械室1a方向に向かう。しかし、バルブベッド3のポケット3a,3bによって、炎の延焼は止まる。   Next, the operation when the resin service panel 6 is ignited will be described. When the resin service panel 6 is ignited, the flame spread is directed toward the machine room 1a. However, the flame spread is stopped by the pockets 3a and 3b of the valve bed 3.

本実施の形態1によれば、樹脂製サービスパネル6の係止ツメ6a,6bは、バルブベッド3のポケット3a,3bにわたり覆われ、機械室1aに露呈されることがないため、サービスパネルが着火して延焼した場合でも、炎が機械室1aに侵入するのを防止することができる。また、バルブベッド3のポケット3a,3bが機械室1aに開口していないので、機械室1aの防音効果を高めることができる。 According to the first embodiment, the locking claw 6a of the resin service panel 6, 6b, because the pocket 3a of the valve bed 3, covered over 3b, not be exposed to the machine room 1a, service panel 6 Even when the flame ignites and spreads, it is possible to prevent the flame from entering the machine room 1a. Moreover, since the pockets 3a and 3b of the valve bed 3 are not open to the machine room 1a, the soundproofing effect of the machine room 1a can be enhanced.

実施の形態2.
図3は本発明の実施の形態2に係る空気調和機の室外ユニットの要部の断面図である。実施の形態1では、バルブベッド3に形成したポケット3a,3bは金属板を絞り加工により構成しているが、本実施の形態2では、絞り形状を緩和するために、ポケット3a,3bの下部にポケット開口部3c,3dを設けたものである。
その他の構成、作用は、実施の形態1に示した場合と実質的に同様なので、説明を省略する。
Embodiment 2. FIG.
FIG. 3 is a cross-sectional view of a main part of an outdoor unit of an air conditioner according to Embodiment 2 of the present invention. In the first embodiment, the pockets 3a and 3b formed in the valve bed 3 are formed by drawing a metal plate, but in the second embodiment, the lower portions of the pockets 3a and 3b are formed in order to relax the drawing shape. Are provided with pocket openings 3c and 3d.
Other configurations and operations are substantially the same as those shown in the first embodiment, and thus the description thereof is omitted.

以上の説明から明らかなように、本実施の形態2によれば、ポケット3a,3bの下部にポケット開口部3c,3dを設けたので、延焼した炎がポケット開口部3c,3dから機械室1aに侵入しやすくなるものの、ポケット開口部3c,3dはポケット3a,3bの下部に配置したので、上方向へ延焼する炎の影響を少なくすることができる。このように、ポケット3a,3bの絞り形状を緩和したので、金型製造費を安価にすることができるとともに、製造工程や材料を少なくすることができ、その結果、部品単価を安価に押さえることができる。   As is apparent from the above description, according to the second embodiment, since the pocket openings 3c and 3d are provided at the lower portions of the pockets 3a and 3b, the flame spread from the pocket openings 3c and 3d causes the machine room 1a. Although the pocket openings 3c and 3d are disposed below the pockets 3a and 3b, the influence of the flame spreading upward can be reduced. As described above, since the shape of the pockets 3a and 3b is relaxed, the mold manufacturing cost can be reduced, and the manufacturing process and materials can be reduced. As a result, the unit cost can be kept low. Can do.
