Description

本発明は、凝縮器を空冷するファンモータを基台に取り付けるための取付構造に関するものである。   The present invention relates to an attachment structure for attaching a fan motor for air-cooling a condenser to a base.

図7に示す如く、製氷機10は、略箱形をなす筐体11の内部を上下に区画して、上方に貯氷室14を画成すると共に、該貯氷室14の下方に冷凍機構17が設置される機械室16を画成している。そして、貯氷室14の内部上方に製氷機構15が配設され、該製氷機構15で製造された角氷Iを貯氷室14内に貯留するようになっている。前記冷凍機構17は、前記製氷機構15を構成する蒸発管(図示せず)に冷媒を循環供給するものであり、前記機械室16の底部に敷設固定される基台18上に配置されている。具体的には、前記機械室16の前面側(製氷機本体の手前側)に凝縮器30が配設され、その奥にファンモータ40が配設され、最も奥側に圧縮機CMが配設されている。なお、前記機械室16の前方右側部分には、前後方向に貫通するスリット19が多数形成されて該機械室16を開放可能に閉成する前面パネル11aが配設されている。また前記機械室16の右方を構成する側面パネル11bに左右方向に貫通するスリット19が多数形成されている。そして、ファンモータ40を駆動することで、前側のスリット19を介して機械室16内に吸い込んだ外部空気で凝縮器30や圧縮機CMを空冷し、熱交換後の空気を右側のスリット19から外部に吹き出すようになっている。   As shown in FIG. 7, the ice making machine 10 divides the interior of a substantially box-shaped housing 11 into upper and lower parts, defines an ice storage chamber 14 above, and a refrigeration mechanism 17 below the ice storage chamber 14. The machine room 16 to be installed is defined. An ice making mechanism 15 is arranged above the ice storage chamber 14, and the ice cubes I manufactured by the ice making mechanism 15 are stored in the ice storage chamber 14. The refrigeration mechanism 17 circulates and supplies a refrigerant to an evaporation pipe (not shown) constituting the ice making mechanism 15, and is disposed on a base 18 that is laid and fixed at the bottom of the machine room 16. . Specifically, the condenser 30 is disposed on the front side of the machine room 16 (the front side of the ice making machine main body), the fan motor 40 is disposed at the back, and the compressor CM is disposed at the farthest side. Has been. A front panel 11 a is formed in the right front portion of the machine room 16 to form a number of slits 19 penetrating in the front-rear direction so that the machine room 16 can be opened. In addition, a number of slits 19 penetrating in the left-right direction are formed in the side panel 11 b that forms the right side of the machine room 16. Then, by driving the fan motor 40, the condenser 30 and the compressor CM are air-cooled by the external air sucked into the machine chamber 16 through the front slit 19, and the air after heat exchange is passed through the right slit 19. It is designed to blow out to the outside.

このような構成の製氷機10においてファンモータ40は、稼働率が高く故障頻度が高い点や、省スペースの問題で前記冷凍機構17が密集している機械室16内に配設されている点を考えて、簡単に取り外しが可能であることが望まれている。そこで、ファンモータ40をブラケットに取り付け、このブラケットを基台に対して固定するようにしていた(例えば、特許文献1参照)。   In the ice making machine 10 having such a configuration, the fan motor 40 is disposed in the machine room 16 where the refrigeration mechanisms 17 are dense due to a high operating rate and high failure frequency, and space saving. In view of the above, it is desired that it can be easily removed. Therefore, the fan motor 40 is attached to a bracket, and the bracket is fixed to the base (for example, see Patent Document 1).

特許文献1に係るファンモータを取り付けたブラケットは、対向する2つの脚部を備え、各脚部の下端には外方に延出する取付フランジが屈曲形成されている。そしてブラケットは、一方の取付フランジを基台に設けたホルダーに差し込んだもとで、他方の取付フランジをネジ部材で該基台に取り付けることで固定されている。また取付フランジは、先端部が所定角度だけ高くなるように傾斜されており、いわゆるスプリング効果を利用してブラケットが基台へ取り付けられている。そのため、ファンモータを取り付けるブラケットの見かけ上の剛性が向上するから、使用時にビビリ振動や、ビビリ音等の異常音の発生が低減される。   The bracket to which the fan motor according to Patent Document 1 is mounted includes two opposing leg portions, and a mounting flange extending outward is bent at the lower end of each leg portion. The bracket is fixed by inserting one mounting flange into a holder provided on the base and attaching the other mounting flange to the base with a screw member. Further, the mounting flange is inclined so that the tip end portion is raised by a predetermined angle, and the bracket is attached to the base using a so-called spring effect. For this reason, the apparent rigidity of the bracket to which the fan motor is attached is improved, so that occurrence of abnormal noise such as chatter vibration and chatter noise during use is reduced.

しかし、特許文献1に係るブラケットを用いたファンモータの取付構造では、ビビリ振動およびビビリ音等の異常音の発生源である該ファンモータから離れた前記脚部の下端のみを基台に固定しているため、ファンモータ付近でのビビリ振動やビビリ音等の異常音の発生を充分に低減できない問題が指摘される。   However, in the fan motor mounting structure using the bracket according to Patent Document 1, only the lower end of the leg part that is a source of abnormal noise such as chatter vibration and chatter noise is fixed to the base. Therefore, a problem is pointed out that the occurrence of abnormal noise such as chatter vibration and chatter noise near the fan motor cannot be sufficiently reduced.

(実施例の作用)
次に、前述のように構成された実施例のファンモータの取付構造の作用について説明する。なお、前記凝縮器30、シュラウド42および基台18は、夫々取付固定されていない状態にあるとする。
(Operation of Example)
Next, the operation of the fan motor mounting structure of the embodiment configured as described above will be described. It is assumed that the condenser 30, the shroud 42, and the base 18 are not attached and fixed.

先ず、図4に示すように前記凝縮器30に対してシュラウド42を位置決めすべく、4つの位置決め爪部48における位置決め部48bを、位置決め孔部35を介して側端部34の後ろ側から前側へ挿通させる。このとき、前記位置決め部48bは下方に突出して形成されているため、前記両側端片46,46は、凝縮器30に取付固定される位置よりも少し高い位置で両側端部34,34に当接する(図4(a)参照)。この状態からシュラウド42を下げれば、各位置決め爪部48における延出部48aの下面が前記位置決め孔部35の下縁部に当接して上下方向の位置決めされると共に、位置決め部48bが側端部34に係合して前後方向の位置決めがなされる。またシュラウド42の上端片44が、前記凝縮器30の上端部30aに覆うように当接する(図4(b)参照)。   First, as shown in FIG. 4, in order to position the shroud 42 with respect to the condenser 30, the positioning portions 48 b in the four positioning claws 48 are moved from the rear side of the side end portion 34 to the front side through the positioning hole portions 35. To pass through. At this time, since the positioning portion 48b is formed so as to protrude downward, the side end pieces 46 and 46 contact the side end portions 34 and 34 at a position slightly higher than the position where the side end pieces 46 and 46 are fixedly attached to the condenser 30. (See FIG. 4 (a)). If the shroud 42 is lowered from this state, the lower surface of the extended portion 48a of each positioning claw portion 48 comes into contact with the lower edge portion of the positioning hole portion 35 and is positioned in the vertical direction, and the positioning portion 48b is positioned on the side end portion. 34 is engaged in positioning in the front-rear direction. Further, the upper end piece 44 of the shroud 42 comes into contact with the upper end portion 30a of the condenser 30 (see FIG. 4B).

この状態において、前記凝縮器30のシュラウド固定ネジ穴34aとシュラウド42のシュラウド固定穴46aとは連通する位置関係となるので、後方からシュラウド固定ネジ26を該固定ネジ穴34aに螺合すれば、前記シュラウド42(ファンモータ40)は凝縮器30を後方から覆うように一体化される。このとき、凝縮器30の上端部30aの略全体にシュラウド42の上端片44が上方から当接し、また側端片46,46の略全体が側端部34,34に後方から面接触状態で当接して固定される。従って、凝縮器30とシュラウド42との固定は非常に強固なものとなる。また前記凝縮器30は、基本的に剛性の高い部材であるので、これに一体化したシュラウド42も見かけ上の剛性が向上してファンモータ40の動作によるビビリ振動やビビリ音等の異常音を効果的に低減し得る。なお、図4においてファンモータ40は省略されている。   In this state, since the shroud fixing screw hole 34a of the condenser 30 and the shroud fixing hole 46a of the shroud 42 are in a communicating relationship, if the shroud fixing screw 26 is screwed into the fixing screw hole 34a from the rear, The shroud 42 (fan motor 40) is integrated so as to cover the condenser 30 from behind. At this time, the upper end piece 44 of the shroud 42 comes into contact with substantially the entire upper end portion 30a of the condenser 30 from above, and substantially the entire side end pieces 46, 46 are in surface contact with the side end portions 34, 34 from the rear. Abutted and fixed. Therefore, the fixing between the condenser 30 and the shroud 42 is very strong. In addition, since the condenser 30 is basically a highly rigid member, the shroud 42 integrated with the condenser 30 is also improved in the apparent rigidity so that abnormal sounds such as chatter vibration and chatter noise caused by the operation of the fan motor 40 are generated. It can be effectively reduced. In FIG. 4, the fan motor 40 is omitted.

次に、一体化された前記凝縮器30およびシュラウド42を、前記基台18に取付固定する場合を説明すると、図5(a)および図6に示す如く、該シュラウド42の係合片49を取付爪部24に係合させるように前方から移動させる。このように係合片49を取付爪部24に係合させると、最終的に前記陥凹部49aに取付爪部24が入り込んで、押さえ部24aの前端に当接する。ここで、前記先端部24bの先端は、所要角度上方に傾斜しているので、係合片49の取付爪部24への係合はスムーズになされる。   Next, the case where the integrated condenser 30 and shroud 42 are attached and fixed to the base 18 will be described. As shown in FIGS. 5 (a) and 6, the engaging piece 49 of the shroud 42 is provided. It is moved from the front so as to engage with the attachment claw portion 24. When the engagement piece 49 is engaged with the attachment claw portion 24 in this manner, the attachment claw portion 24 finally enters the recessed portion 49a and comes into contact with the front end of the pressing portion 24a. Here, since the tip end of the tip end portion 24b is inclined upward by a required angle, the engagement of the engagement piece 49 with the attachment claw portion 24 is smoothly performed.

また、前記基台18の上面と先端部24bの下面との間の距離は、係合片49における係合部分の厚さと略同等に設定されているため、該係合片49を取付爪部24に係合させたシュラウド42の上方向へのずれは好適に抑制される(図5(a)参照)。更に、前記押さえ部24aの幅と、陥凹部49aの幅とは略同等に設定されているため、前記シュラウド42の左右方向へのずれも好適に防止される(図6参照)。そして、前記係合片49を取付爪部24に係合させることで、凝縮器固定ネジ穴22,22の位置と、両凝縮器固定穴32a,32aの位置とが一致する。   Further, since the distance between the upper surface of the base 18 and the lower surface of the distal end portion 24b is set substantially equal to the thickness of the engaging portion of the engaging piece 49, the engaging piece 49 is attached to the mounting claw portion. The upward displacement of the shroud 42 engaged with 24 is preferably suppressed (see FIG. 5A). Furthermore, since the width of the pressing portion 24a and the width of the recessed portion 49a are set to be substantially equal, the displacement of the shroud 42 in the left-right direction is preferably prevented (see FIG. 6). Then, by engaging the engagement piece 49 with the attachment claw portion 24, the positions of the condenser fixing screw holes 22, 22 and the positions of the condenser fixing holes 32a, 32a coincide.

この状態において、上方から各凝縮器固定穴32aに連通した凝縮器固定ネジ28を凝縮器固定ネジ穴22に螺合することで、一体化された凝縮器30とシュラウド42(ファンモータ40)とが前記基台18に固定される。そして、前記シュラウド42における各取付部50に、対応してドライヤー51およびチャージポート52を取り付ける。なお、図5および図6においてファンモータ40は省略されている。   In this state, the condenser fixing screw 28 communicated with each condenser fixing hole 32a from above is screwed into the condenser fixing screw hole 22 to thereby integrate the condenser 30 and the shroud 42 (fan motor 40). Is fixed to the base 18. Then, a dryer 51 and a charge port 52 are attached to each attachment portion 50 in the shroud 42 correspondingly. 5 and 6, the fan motor 40 is omitted.

前記シュラウド42の上端片44が該凝縮器30の上端部30aを上方からが覆うように当接し、該シュラウド42の側端片46,46が該凝縮器30の両側端部34,34を後方から当接してなされる該凝縮器30とシュラウド42との固定は、固定箇所が多くかつ分散して存在しているため、安定度が高く、ビビリ振動やビビリ音の異常音を大きく低減し得る効果を奏する。
また、後面が平面となっている側端部34,34と、前面が平面となっている側端片46,46とが面接触状態で当接するので、凝縮器30とシュラウド42との固定は非常に強固なものとし得る効果を奏する。また、前記基台18の上面と先端部24bの下面との間の距離は、係合片49における係合部分の厚さと略同等に設定され、
更に、押さえ部24aの幅と、陥凹部49aの幅とは略同等に設定されているため、該係合片49を取付爪部24に係合させたシュラウド42の上方向および左右方向へのずれは好適に抑制される。このずれの防止により、一体化した凝縮器30およびシュラウド42と基台18との固定が容易となる効果を奏する。
また更に、前期位置決め爪部48における延出部48aの下面が、位置決め孔部35の下縁部に当接して上下方向の位置決めされると共に、位置決め部48bが側端部34に係合して前後方向の位置決めがなされるため、凝縮器30とシュラウド42との固定が容易となる効果を奏する。
The upper end piece 44 of the shroud 42 is in contact with the upper end portion 30a of the condenser 30 so as to cover the upper end portion 30a from above, and the side end pieces 46, 46 of the shroud 42 are located behind the opposite side end portions 34, 34 of the condenser 30. The condenser 30 and the shroud 42 fixed in contact with each other have a high degree of stability because there are many fixed portions and are dispersed, and can greatly reduce chatter vibration and abnormal chatter noise. There is an effect.
Further, since the side end portions 34, 34 whose rear surfaces are flat and the side end pieces 46, 46 whose front surfaces are flat contact each other in a surface contact state, the condenser 30 and the shroud 42 are fixed. There is an effect that can be very strong. Further, the distance between the upper surface of the base 18 and the lower surface of the tip 24b is set to be approximately equal to the thickness of the engaging portion of the engaging piece 49,
Furthermore, since the width of the pressing portion 24a and the width of the recessed portion 49a are set to be substantially equal, the upward direction and the left / right direction of the shroud 42 in which the engaging piece 49 is engaged with the mounting claw portion 24 are set. The shift is preferably suppressed. By preventing this shift, the integrated condenser 30 and shroud 42 and the base 18 can be easily fixed.
Furthermore, the lower surface of the extended portion 48a of the positioning claw portion 48 in the previous period contacts the lower edge portion of the positioning hole portion 35 and is positioned in the vertical direction, and the positioning portion 48b is engaged with the side end portion 34. Since positioning in the front-rear direction is performed, the condenser 30 and the shroud 42 can be easily fixed.

また、前記シュラウド42に各種冷凍機構成部品を取り付ける取付部50を設けることで、以下の作用を奏する。すなわち、(a)前記冷凍機構成部品を固定する固定具に係る部品点数を省略し得る、(b)冷凍機構17全体がシュラウド42の剛性向上に資するため、該シュラウド42のビビリ振動やビビリ音の異常音を低減し得る、(c)取付部50への冷凍機構成部品嵌合の取り付けは嵌合等でなされているので、該冷凍機構成部品の着脱が容易に可能となる。   Further, by providing the shroud 42 with the attachment portion 50 for attaching various refrigerator components, the following effects are exhibited. That is, (a) the number of parts related to the fixture for fixing the refrigerator components can be omitted. (B) Since the entire refrigeration mechanism 17 contributes to the improvement of the rigidity of the shroud 42, chatter vibration and chatter noise of the shroud 42 are provided. (C) Since mounting of the refrigerator component parts to the mounting portion 50 is performed by fitting or the like, the refrigerator component parts can be easily attached and detached.
