The electrical component 12 is inserted into and fixed to the glass terminal 11 provided in the compressor 10, and power is supplied to the compressor 10. When power is supplied to the compressor 10, the refrigerant gas is compressed by the compression element stored in the compressor 10, and flows into the refrigeration cycle of the refrigerator 100 through the discharge pipe 13. The gas refrigerant that has been cooled by the refrigeration cycle of the refrigerator 100 is returned into the compressor 10 through the suction pipe 14.
　以上のように冷蔵庫１００は、電装品保護装置１６の下壁部２０ｅの外壁面において係止爪２３の反対側から突出した引掛部２１を有する。この引掛部２１は、下壁部２０ｅと対向する板状に形成された平板部２１ａを有し、平板部２１ａが、下壁部２０ｅとの間に、側壁部２０ａ側から前壁部２０ｃ側にかけて連続して開口した空隙２１ｅを形成するものである。そのため、作業者が、保護カバー２０をブラケット１８から取り外すために冷蔵庫１００の背面側から作業する場合に、工具３０を電装品保護装置１６の側面側から正面側にかけて開口した空隙２１ｅに挿入することができる。また、作業者が、挿入した工具３０を電装品保護装置１６の側面側から正面側にかけて動かすことができる。その結果、作業者は、ブラケット１８から保護カバー２０を取り外す際に、引掛部２１への工具３０の挿入と挿入後の移動とが、冷蔵庫１００の外側壁部４と保護カバー２０の外郭となる側壁部２０ａ及び前壁部２０ｃに妨げられずに作業を行うことができる。 As described above, the refrigerator 100 has the hook 21 projecting from the opposite side of the locking claw 23 on the outer wall surface of the lower wall 20 e of the electric component protection device 16. The hooking portion 21 has a flat plate portion 21a formed in a plate shape facing the lower wall portion 20e, and the flat plate portion 21a is between the side wall portion 20a side and the front wall portion 20c side with the lower wall portion 20e. The gap 21e which is continuously opened is formed. Therefore, when the worker works from the back side of the refrigerator 100 to remove the protective cover 20 from the bracket 18, the tool 30 is inserted into the gap 21e opened from the side of the electrical component protection device 16 to the front side. Can. In addition, the worker can move the inserted tool 30 from the side to the front of the electrical component protection device 16. As a result, when the worker removes the protective cover 20 from the bracket 18, the insertion of the tool 30 into the hooking portion 21 and the movement after the insertion become the outer wall of the refrigerator 100 and the outer cover of the protective cover 20. The work can be performed without being disturbed by the side wall portion 20a and the front wall portion 20c.
　また、冷蔵庫１００は、保護カバー２０が側壁部２０ａと下壁部２０ｅとの稜線に沿って前壁部２０ｃまで形成された凹部２２を有するものである。そのため、作業者が、保護カバー２０をブラケット１８から取り外すために冷蔵庫１００の背面側から作業する場合に、工具３０を電装品保護装置１６の側面側から正面側にかけて開口した空隙２１ｅに挿入することができる。また、作業者が、挿入した工具３０を電装品保護装置１６の側面側から正面側にかけて動かすことができる。その結果、作業者は、ブラケット１８から保護カバー２０を取り外す際に、引掛部２１への工具３０の挿入と、挿入後の移動とが、冷蔵庫１００の外側壁部４と保護カバー２０の外郭となる側壁部２０ａ及び前壁部２０ｃに妨げられずに作業を行うことができる。 Moreover, the refrigerator 100 has the recessed part 22 in which the protective cover 20 was formed to the front wall part 20c along the ridgeline of the side wall part 20a and the lower wall part 20e. Therefore, when the worker works from the back side of the refrigerator 100 to remove the protective cover 20 from the bracket 18, the tool 30 is inserted into the gap 21e opened from the side of the electrical component protection device 16 to the front side. Can. In addition, the worker can move the inserted tool 30 from the side to the front of the electrical component protection device 16. As a result, when the operator removes the protective cover 20 from the bracket 18, the insertion of the tool 30 into the hooking portion 21 and the movement after insertion are the outer wall 4 of the refrigerator 100 and the outer shell of the protective cover 20. The work can be performed without being hindered by the side wall portion 20a and the front wall portion 20c.
　また、冷蔵庫１００は、空隙２１ｅを形成する引掛部２１と、保護カバー２０が側壁部２０ａと下壁部２０ｅとの稜線に沿って前壁部２０ｃまで形成された凹部２２を有するものである。そのため、作業者は、圧縮機１０に接続されているチャージパイプ１５等の配管により、作業スペースが十分確保できない場合でも、工具３０の挿入域の広さと可動域の広さとから、保護カバー２０をブラケット１８からスムーズに取り外すことができる。 In addition, the refrigerator 100 has a hook 21 that forms the air gap 21e, and a recess 22 in which the protective cover 20 is formed along the ridge line between the side wall 20a and the lower wall 20e to the front wall 20c. Therefore, the worker can protect the protective cover 20 from the size of the insertion area of the tool 30 and the size of the movable area even when the working space can not be secured sufficiently by the piping such as the charge pipe 15 connected to the compressor 10.

The locking claw 25 of the protective cover 120 is locked to the locking portion 18 c of the bracket 18, whereby the protective cover 120 is fixed to the bracket 18.
［電装品保護装置１６Ａの分解］
　電装品保護装置１６Ａの分解について説明する。電装品保護装置１６Ａの分解方法の１つは、図７及び図８で示す電装品保護装置１６と同じである。保護カバー１２０をブラケット１８から取り外す場合、係止部１８ｃに係止された保護カバー１２０の係止爪２５を係止孔１８ｄから取り外す必要がある。作業者は、保護カバー１２０の下壁部２０ｅに設けられた引掛部２１の空隙２１ｅにマイナスドライバー等の工具３０の先端を挿入する。引掛部２１の平板部２１ａと下壁部２０ｅとの間の空隙２１ｅは、冷蔵庫２００を背面側から見た場合に、保護カバー１２０の幅方向（Ｘ軸方向）において左側から保護カバー１２０の奥行方向（Ｙ軸方向）において前側にかけて開口している。そのため、作業者は、工具３０を電装品保護装置１６Ａの左側面側から正面側にかけて引掛部２１に挿入することができ、工具３０を引掛部２１の空隙２１ｅに挿入する際に、冷蔵庫２００の側壁に妨げられることはない。 [Decomposition of electrical equipment protection device 16A]
The disassembly of the electrical component protection device 16A will be described. One of the methods for disassembling the electrical component protection device 16A is the same as the electrical component protection device 16 shown in FIGS. 7 and 8. When the protective cover 120 is removed from the bracket 18, it is necessary to remove the locking claws 25 of the protective cover 120 locked to the locking portion 18c from the locking hole 18d. The operator inserts the tip of a tool 30 such as a flathead screwdriver into the gap 21 e of the hook 21 provided on the lower wall 20 e of the protective cover 120. When the refrigerator 200 is viewed from the rear side, the gap 21e between the flat plate portion 21a and the lower wall portion 20e of the hooking portion 21 is a depth of the protective cover 120 from the left side in the width direction (X axis direction) of the protective cover 120 It is open toward the front side in the direction (Y-axis direction). Therefore, the worker can insert the tool 30 into the hooking portion 21 from the left side to the front side of the electric component protection device 16A, and when inserting the tool 30 into the gap 21e of the hooking portion 21, the refrigerator 200 There is no hindrance to the side walls.
　次に、作業者は、工具３０によって、保護カバー１２０の引掛部２１を下方に引き下げると同時に工具３０の持ち手部分を起こすように回転力Ｒ１を加える。作業者が、工具３０をこのように動かすことで、係止爪２５を係止孔１８ｄから取り外すことができ保護カバー１２０とブラケット１８との固定を解除することができる。保護カバー１２０は、側壁部２０ａと下壁部２０ｅとの稜線に沿って前壁部２０ｃまで形成された凹部２２Ａを有している。そのため、作業者は、工具３０を電装品保護装置１６Ａの左側面側から正面側にかけて保護カバー１２０の引掛部２１を下方に引き下げると同時に工具３０の持ち手部分を起こすように回転力Ｒ１を加えることができる。その結果、作業者は、工具３０を動かす際に、保護カバー１２０の側壁に動きを妨げられることはない。作業者は、工具３０を電装品保護装置１６Ａの左側面側から正面側にかけて配置することができることで、作業を行いやすい。 Next, the operator pulls down the hooking portion 21 of the protective cover 120 with the tool 30 and simultaneously applies a rotational force R1 to raise the handle portion of the tool 30. By moving the tool 30 in this manner, the worker can remove the locking claws 25 from the locking holes 18 d, and can release the fixation between the protective cover 120 and the bracket 18. The protective cover 120 has a recess 22A formed along the ridge line between the side wall 20a and the lower wall 20e to the front wall 20c. Therefore, the operator pulls down the hooking portion 21 of the protective cover 120 downward from the left side to the front side of the electrical component protection device 16A and simultaneously applies the rotational force R1 to raise the handle of the tool 30. be able to. As a result, when the operator moves the tool 30, the side wall of the protective cover 120 is not prevented from moving. The worker can easily perform the work because the tool 30 can be disposed from the left side to the front of the electrical component protection device 16A.
　図１３は、本発明の実施の形態２に係る冷蔵庫２００において、電装品保護装置１６Ａの保護カバー１２０をブラケット１８から取り外す際の断面図である。更に電装品保護装置１６Ａは、他の方法で、ブラケット１８から保護カバー１２０を取り外すことができる。保護カバー１２０の凹部２２Ａには、下壁部２０ｅと、前壁部２０ｃと、中間下壁部２２ｅと、中間前壁部２２ｃとによって貫通した開口部２６が形成されている。また、保護カバー１２０の下壁部２０ｅの内壁面には、係止爪２５が形成されている。係止爪２５のテーパ部２５ａは、側壁部２０ａからブラケット１８に向かって肉厚が大きくなるように形成されている。そのため、作業者は、マイナスドライバー等の工具３０を開口部２６に挿入するだけで、保護カバー１２０の下壁部２０ｅを下方向へ引き下げることができる。その結果、作業者は、工具３０によって下壁部２０ｅを下方向へ引き下げる為の力を使わなくても、工具３０を開口部２６に挿入するだけで、保護カバー１２０とブラケット１８との固定を外すことができ、保護カバー１２０をスムーズに取り外すことができる。 FIG. 13 is a cross-sectional view at the time of removing the protective cover 120 of the electrical component protecting device 16A from the bracket 18 in the refrigerator 200 according to the second embodiment of the present invention. Furthermore, the electrical equipment protection device 16A can remove the protective cover 120 from the bracket 18 in other ways. In the recess 22A of the protective cover 120, an opening 26 is formed through the lower wall 20e, the front wall 20c, the middle lower wall 22e, and the middle front wall 22c. In addition, a locking claw 25 is formed on the inner wall surface of the lower wall portion 20 e of the protective cover 120. The tapered portion 25 a of the locking claw 25 is formed to increase in thickness from the side wall portion 20 a toward the bracket 18. Therefore, the worker can pull down the lower wall 20 e of the protective cover 120 only by inserting the tool 30 such as a flathead screwdriver into the opening 26. As a result, the worker can fix the protective cover 120 to the bracket 18 simply by inserting the tool 30 into the opening 26 without using the force to pull the lower wall 20 e downward with the tool 30. The protective cover 120 can be removed smoothly.
［冷蔵庫２００及び圧縮機１０の動作］
　圧縮機１０に設けられたガラスターミナル１１に電装品１２が挿入固定され、圧縮機１０に電源が供給される。圧縮機１０に電源が供給されると、圧縮機１０に収納された圧縮要素により、冷媒ガスが圧縮され、吐出管１３を通って冷蔵庫２００の冷凍サイクルに流入する。冷蔵庫２００の冷凍サイクルにより冷却作用を行ったガス冷媒は、吸入管１４を通って圧縮機１０内へと戻される。 [Operation of Refrigerator 200 and Compressor 10]
The electrical component 12 is inserted into and fixed to the glass terminal 11 provided in the compressor 10, and power is supplied to the compressor 10. When power is supplied to the compressor 10, the refrigerant gas is compressed by the compression element stored in the compressor 10, and flows into the refrigeration cycle of the refrigerator 200 through the discharge pipe 13. The gas refrigerant that has been cooled by the refrigeration cycle of the refrigerator 200 is returned into the compressor 10 through the suction pipe 14.
　以上のように冷蔵庫２００は、電装品保護装置１６Ａの下壁部２０ｅの外壁面において係止爪２５の反対側から突出した引掛部２１を有する。この引掛部２１は、下壁部２０ｅと対向する板状に形成された平板部２１ａを有し、平板部２１ａが、下壁部２０ｅとの間に、側壁部２０ａ側から前壁部２０ｃ側にかけて連続して開口した空隙２１ｅを形成するものである。そのため、作業者が、保護カバー１２０をブラケット１８から取り外すために冷蔵庫２００の背面側から作業する場合に、工具３０を電装品保護装置１６Ａの側面側から正面側にかけて開口した空隙２１ｅに挿入することができる。また、作業者が、挿入した工具３０を電装品保護装置１６の側面側から正面側にかけて動かすことができる。その結果、作業者は、ブラケット１８から保護カバー１２０を取り外す際に、引掛部２１への工具３０の挿入と挿入後の移動とが、冷蔵庫２００の外側壁部４と保護カバー１２０の外郭となる側壁部２０ａ及び前壁部２０ｃに妨げられずに作業を行うことができる。 As mentioned above, the refrigerator 200 has the hooking part 21 which protruded from the opposite side of the latching claw 25 in the outer wall surface of the lower wall part 20e of 16 A of electrical component protection devices. The hooking portion 21 has a flat plate portion 21a formed in a plate shape facing the lower wall portion 20e, and the flat plate portion 21a is between the side wall portion 20a side and the front wall portion 20c side with the lower wall portion 20e. The gap 21e which is continuously opened is formed. Therefore, when the worker works from the back side of the refrigerator 200 in order to remove the protective cover 120 from the bracket 18, the tool 30 is inserted into the gap 21e opened from the side of the electrical component protection device 16A to the front. Can. In addition, the worker can move the inserted tool 30 from the side to the front of the electrical component protection device 16. As a result, when the worker removes the protective cover 120 from the bracket 18, the insertion of the tool 30 into the hooking portion 21 and the movement after the insertion become the outer wall of the refrigerator 200 and the outer wall of the protective cover 120. The work can be performed without being disturbed by the side wall portion 20a and the front wall portion 20c.
　また、冷蔵庫２００は、保護カバー１２０が側壁部２０ａと下壁部２０ｅとの稜線に沿って前壁部２０ｃまで形成された凹部２２Ａを有するものである。そのため、作業者が、保護カバー１２０をブラケット１８から取り外すために冷蔵庫２００の背面側から作業する場合に、工具３０を電装品保護装置１６Ａの側面側から正面側にかけて開口した空隙２１ｅに挿入することができる。また、作業者が、挿入した工具３０を電装品保護装置１６の側面側から正面側にかけて動かすことができる。その結果、作業者は、ブラケット１８から保護カバー１２０を取り外す際に、引掛部２１への工具３０の挿入と挿入後の移動とが、冷蔵庫２００の外側壁部４と保護カバー１２０の外郭となる側壁部２０ａ及び前壁部２０ｃに妨げられずに作業を行うことができる。 Moreover, the refrigerator 200 has the recessed part 22A in which the protective cover 120 was formed to the front wall part 20c along the ridgeline of the side wall part 20a and the lower wall part 20e. Therefore, when the worker works from the back side of the refrigerator 200 in order to remove the protective cover 120 from the bracket 18, the tool 30 is inserted into the gap 21e opened from the side of the electrical component protection device 16A to the front. Can. In addition, the worker can move the inserted tool 30 from the side to the front of the electrical component protection device 16. As a result, when the worker removes the protective cover 120 from the bracket 18, the insertion of the tool 30 into the hooking portion 21 and the movement after the insertion become the outer wall of the refrigerator 200 and the outer wall of the protective cover 120. The work can be performed without being disturbed by the side wall portion 20a and the front wall portion 20c.
　また、冷蔵庫２００は、空隙２１ｅを形成する引掛部２１と、保護カバー１２０が側壁部２０ａと下壁部２０ｅとの稜線に沿って前壁部２０ｃまで形成された凹部２２Ａを有するものである。そのため、作業者は、圧縮機１０に接続されているチャージパイプ１５等の配管により、作業スペースが十分確保できない場合でも、工具３０の挿入域の広さと可動域の広さとから、保護カバー１２０をブラケット１８からスムーズに取り外すことができる。 Moreover, the refrigerator 200 has the hook part 21 which forms the clearance gap 21e, and the recessed part 22A in which the protective cover 120 was formed to the front wall part 20c along the ridgeline of the side wall part 20a and the lower wall part 20e. Therefore, the worker can protect the protective cover 120 from the size of the insertion area of the tool 30 and the size of the movable area even when the working space can not be secured sufficiently by the piping such as the charge pipe 15 connected to the compressor 10. It can be removed smoothly from the bracket 18.

The tapered portion 25 a of the locking claw 25 is formed to increase in thickness from the side wall portion 20 a toward the bracket 18. Therefore, the worker can pull down the lower wall 20 e of the protective cover 120 only by inserting the tool 30 such as a flathead screwdriver into the opening 26. As a result, the worker can fix the protective cover 120 to the bracket 18 simply by inserting the tool 30 into the opening 26 without using the force to pull the lower wall 20 e downward with the tool 30. The protective cover 120 can be removed smoothly.
