Title: Wire fixing structure, electrical equipment mount device and air conditioner using the same

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a wire fixing structure, an electrical equipment mount device having the wire fixing structure, and an air conditioner having the electrical equipment mount device and including an indoor heat exchanger, an indoor fan, an outdoor heat exchanger and an outdoor fan which are integrally equipped. 
     2. Description of the Related Art 
     There has been known an integral-type air conditioner in which an indoor heat exchanger, an indoor fan, an outdoor heat exchanger and an outdoor fan are integrally assembled and also the inside of the air conditioner is partitioned into an indoor-side chamber having the indoor heat exchanger and the indoor fan arranged therein and an outdoor-side chamber having the outdoor heat exchanger and the outdoor fan arranged therein by a partition plate. The air conditioner is further equipped with an operating portion having various kinds of electrical parts such as circuit boards, control buttons, etc. for controlling the compressor, the indoor fan, the outdoor fan, etc. 
     The air conditioner thus constructor has a cabinet which is disposed so as to penetrate through the wall of a building while the outer heat exchanger, the outdoor fan, etc. are accommodated therein, and a front panel which is fixed to the front end portion of the cabinet and disposed so as to project toward the room. The front panel is equipped with a laterally-elongated opening portion at the upper portion thereof and an air blow-out grille which is disposed in juxtaposition with the operating portion in the horizontal direction. 
     In the air conditioner thus constructed, the operating portion has an electrical equipment mount device disposed inside the cabinet and/or the front panel. A circuit board such as a control board for controlling the compressor, the indoor fan, the outdoor fan, etc. or the like on which electrical parts are mounted is disposed on the electrical equipment mount device. The electrical equipment mount device is disposed substantially beneath an operation door covering the opening portion as disclosed by Post-examined Utility Model Application No. Hei-4-40110). 
     In the operating portion thus constructed, various wires such as electrical wires for power supply, etc. are connected to a power supply circuit equipped to the control board, and these electrical wires are fixed to the wire fixing face of the electrical equipment mount device by fixing the electrical wires onto the wire fixing face with a pressing member or the like. Particularly in the case where a high voltage (for example, 265V) is supplied to the control circuit through the electrical wires for power supply, the electrical wires for power supply are disposed while inserted in a conduit in order to protect the electric wires from the external force. 
     When such an integral type air conditioner is set up in a room of a building, the air conditioner is usually set up in the room so that the cabinet disposed so as to penetrate through the wall of the building is located at the height corresponding to the waist of a user. In this case, the user may put a glass containing liquid such as drinking water or the like on the front panel or the cabinet. If the glass is turned over, the liquid drops through the operation opening into the electrical equipment mount device, thereby inducing insulation failure of the electrical parts. 
     Further, when the electric wires are fixed to the wire fixing face of the electrical equipment mount device as described above, the electric wires are fixed between the wire fixing face of the electrical equipment mount device and the press member. When the electric wires are used for power supply, the diameter of each electric wire is varied in accordance with the magnitude of the power to be supplied. Therefore, the press member for fixing the electric wires against the wire fixing face must be varied in shape in accordance with the wire diameter of the electric wires being used, and thus plural kinds of press members must be prepared to fix the electric wires being used to the wire fixing face. Therefore, the number of press members (parts) is increased, so that the cost of the air conditioner rises up. 
     In addition, in the case where a conduit is equipped to protect the electrical wires from the external force as described above, as disclosed in Japanese Post-examined Utility Model Application No. Hei-4-5935, a conduit fixing member for fixing conduits to the lower panel of a heat exchanger is constructed as a projecting piece which is integrally formed on a large-size plate (lower panel). In this case, a screwed fixing member is equipped to the tip of each conduit. The tip portions of the conduit penetrate through fixing holes formed in the conduit fixing member (the projecting piece), and then the screwed fixing members of the conduits are threadedly engaged with nuts to thereby fix the conduits to the conduit fixing member, so that the electrical wires can be excellently protected from the force acting on the conduits. In this case, the conduit fixing member for fixing the conduits to the lower panel must be designed as a large-size part (projecting piece) integrally formed with the lower panel. Further, the lower panel is fixed to the front panel and the back panel by using many screws. Accordingly, it is cumbersome to fix the lower panel having the projecting piece to the front and back panels, and the manufacturing cost rises up because it needs many screws.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Preferred embodiments according to the present invention will be described hereunder with reference to the accompanying drawings. 
     FIG. 1 is a perspective view showing the outlook of an air conditioner according to the present invention particularly when the air conditioner is set up at the height corresponding the waist position of users on the wall of a building so as to penetrate through the wall, and FIG. 2 is an exploded perspective view showing the air conditioner of FIG. 1 when a cabinet is omitted from the illustration. When the air conditioner is set up, a part of the cabinet is projected to the room side (for example, it is projected to the room side by about 70 mm, for example), and the other part thereof outwardly penetrates through the wall of the building. 
     The air conditioner  10  shown in FIGS. 1 and 2 is an integral-type air conditioner which is set up while penetrating through the wall of the building, and it comprises an indoor heat exchanger  11 , a cross-flow fan  12  (FIG. 3) serving as an indoor fan, an outdoor heat exchanger  13 , a propeller fan  14  serving as an outdoor fan, a compressor  15 , etc. which are integrally fabricated. 
     The indoor heat exchanger  11 , the cross-flow fan  12 , the outdoor heat exchanger  13 , the propeller fan  14 , the compressor  15 , etc. are disposed on the bottom plate  16  to constitute the main body  17  of the air conditioner. The front side of the air-conditioner main body  17  (that is, the arrangement side of the indoor heat exchanger  11  and the cross-flow fan  12 ) is covered by a front panel  18 , and the rear side thereof (that is, the arrangement side of the outdoor heat exchanger  13 , the propeller fan  14  and the compressor  15 ) is covered by a cabinet  19 . The front panel  18  is located to face the inside of the room of the building. The cabinet  19  is set up in the wall of the building while it penetrates through the wall of the building, and the cabinet  19  is designed to have a sleeve-like shape such as a cylindrical shape, a prismatic shape or the like. 
     As shown in FIGS. 3 and 4, in the air-conditioner main body  17 , a partition plate  20  is erectly equipped at the substantially center position in the front and rear direction of the bottom plate  16  so as to extend in the full-width direction of the bottom plate  16 . The partition plate  20  compartments the inside of the air-conditioner main body  17  into an indoor-side chamber  21  in which the indoor heat exchanger  11 , the cross-flow fan  12 , etc. are arranged and an outdoor-side chamber  22  in which the outdoor heat exchanger  13 , the propeller fan  14 , the compressor  15 , etc. are arranged. Accordingly, the front panel  18  disposed at the front side of the air conditioner  10  covers the indoor-side chamber  21 , and the cabinet  19  disposed at the rear side of the air conditioner  10  compartment the surrounding of the outdoor-side chamber  22 . 
     The outdoor heat exchanger  13 , an outdoor fan casing  23 , a support leg  24  and the compressor  15  are disposed at the outdoor-side chamber side on the bottom plate  16 . 
     The compressor  15  is connected to the outdoor heat exchanger  13 , a pressure reducing device (not shown) and the indoor heat exchanger in this order through a refrigerant pipe (not shown), thereby constructing a refrigeration cycle. When the air conditioner  10  is under cooling operation, the outdoor heat exchanger  13  functions as a condenser, and the indoor heat exchanger  11  functions as an evaporator. When the air conditioner  10  is under heating operation, the outdoor heat exchanger  13  functions as an evaporator, and the indoor heat exchanger  11  functions as a condenser. 
     The outdoor fan casing  23  is disposed so as to be connected t the outdoor heat exchanger  13 , and the propeller fan  14  is disposed inside the outdoor fan casing  23 . The propeller fan  14  is rotated by an outdoor driving motor  25 , and the outdoor driving motor  25  is supported on the support leg  24  The outdoor-side chamber  22  is partitioned into an outdoor discharge chamber at the inside of the outdoor fan casing  23  and an outdoor suction chamber  27  at the outside of the outdoor fan casing  23  by the outdoor fan casing  23 . 
     By rotation of the propeller fan  14 , the outside air is sucked from the outdoor suction ports  28  at both the sides of the outdoor heat exchanger  13  into the outdoor suction chamber  27  as shown by arrows A of FIG. 4, passed through the a fan orifice  29  of the outdoor fan casing  23  and then discharged into the outdoor discharge chamber  26 . Thereafter, the outside air is passed through the outdoor heat exchanger  13  and then discharged from the outdoor discharge port  30  to the outside. Under the cooling operation of the air conditioner  10 , the outdoor heat exchanger  13  discharge heat to the outside air, and under the heating operation of the air conditioner  10 , the outdoor heat exchanger  13  takes heat from the outside air. 
     As shown in FIG. 3, each vane of the propeller fan  14  is equipped with a slinger ring on the outer peripheral portion thereof to link the vanes to one another. Under the cooling operation of the air conditioner  10 , drain water occurs on the indoor heat exchanger  11  serving as the evaporator. The drain water is collected in a drain pan  33  as described later, and then it is passed through a drain opening  44  formed at the lower end portion of the partition plate  20  and stocked into a reservoir portion  32  disposed on the bottom plate  16 . The slinger ring  31  drains up the drain water stocked in the reservoir portion  32  when the propeller fan  14  is rotated, and the drain water thus drained up is scattered to the outdoor heat exchanger  13  functioning as the condenser, whereby the condensation function of the outdoor heat exchanger is enhanced. 
     The drain pan  33  is disposed at the indoor-side chamber side on the bottom plate  16 , and the indoor heat exchanger  11  is disposed on the drain pan  33 . The partition plate  20  is designed in a box-shape having an opening at the indoor-side chamber side, and an indoor fan casing  34  is disposed inside the partition plate  20 . 
     The indoor fan casing  34  is curved from the position corresponding to a first top panel  41  (described later) of the partition plate  20  and extends to the drain pan  33 , and an electrical heater  55  is disposed at the lower end portion of the drain pan  33  so as to be adjacent to the indoor heat exchanger  11 . A cross-flow fan  12  is disposed at the inside of the curved indoor fan casing. Accordingly, the indoor fan casing  34  is disposed between the partition plate  20  and the cross-flow fan  12 . 
     The cross-flow fan  12  is rotated by an indoor driving motor  35  shown in FIG. 4, and the cross-flow fan  12  and the indoor driving motor  35  are supported on the partition plate  20 . The indoor fan casing  34  forms an indoor circulating chamber  36  and an outside air introducing chamber  37  at the indoor-side chamber side as shown in FIG.  3 . Further, as shown in FIG. 4, an electrical-equipment chamber  46  in which an electrical-equipment mount device  45  is accommodated is formed at the indoor-side chamber side. 
     The indoor heat exchanger  11 , the cross-flow fan  12  and the electrical heater  55  are disposed in the indoor circulating chamber  36  as shown in FIG.  3 . Further, an air filter  38  and a stabilizer  39  are disposed in the indoor circulating chamber  36 . The air filter  38  is disposed between a suction grille  40  formed in a front panel  18  and the indoor heat exchanger  11 . The stabilizer  39  is disposed at the upper side of the indoor heat exchanger  11  so as to extend to the cross-flow fan  12 . By the stabilizer  39 , the air in the indoor circulating chamber  36  is excellently sucked to the indoor heat exchanger  11 , and then excellently discharged from the indoor heat exchanger  11 . A blow-out grille  43  for guiding the discharged air into the room of the building is formed at the upper side of the suction grille  40  on the front panel  18 . 
     The air in the room of the building is taken from the suction grille  40  into the indoor circulating chamber  36  of the indoor-side chamber  21  by the rotation of the cross-flow fan  12 . The air thus taken is passed through the air filter  38 , the indoor heat exchanger  11  and the electrical heater  55  in this order, and then sucked into the cross-flow fan  12 . Thereafter, the air is discharged from the cross-flow fan  12 , and blown out from the blow-out grille  43  into the room. Under the cooling operation of the air conditioner  10 , the indoor heat exchanger  11  cools the indoor air taken in the indoor circulating chamber  36  to cool the inside of the room. Under the heating operation, the indoor air is heated to heat the inside of the room. 
     The outside air introducing chamber  37  is one of constituent elements constituting a ventilation device for taking the outside air from the outdoor-side chamber  22  into the indoor circulating chamber  36  of the indoor-side chamber  21 , whereby fresh air can be supplied into the room of the building. The ventilation device  47  is constructed by ventilation ports  48 , a ventilation shutter  49  and a ventilation aeration portion  50 A in addition to the outside air introducing chamber  37 . 
     A second top panel  42  is formed at the lower position than the first top panel  41  on the box-shaped partition plate  20  so as to intercommunicate with the first top panel  41 . The second top panel  42  is disposed inside the cabinet  19  compartmenting the surrounding of the outdoor-side chamber  22 . As shown in FIGS. 4 and 5, a plurality of ventilation ports  48  are formed in the second top panel  42  to be juxtaposed with one another at the same pitch in the longitudinal direction of the second top panel  42 . 
     A ventilation shutter  49  having many fine holes  51  formed therein is mounted on the second top panel  42 . These fine holes  51  are gathered every group, and plural fine-hole groups  51 A are arranged at the same pitch in the longitudinal direction of the ventilation shutter  49 . The pitch of the fine-hole groups  51 A is set to substantially the same pitch as the ventilation ports  48  of the second top panel  42 . 
     Elongated holes  52  extending in the longitudinal direction of the ventilation shutter  49  are formed at both the end portions of the ventilation shutter  49 . The ventilation shutter  49  is fixed to the second top panel  42  of the partition plate  20  through screws penetrating through the elongated holes  52  so as to be freely slidable in the longitudinal direction of the second top panel  42  and the ventilation shutter  49 . 
     As shown in FIG. 6, the ventilation ports  48  are fully opened at the position where the fine-hole groups  51 A of the ventilation shutter  49  are positionally coincident with the ventilation ports  48  by sliding the ventilation shutter  49 . On the other hand, the ventilation ports  48  are fully closed at the position where the fine-hole groups  51 A are not positionally coincident with the ventilation ports  48 . Further, by sliding the ventilation shutter  49  to any position between the full-open position and the full-close position, the opening degree of the ventilation ports  48  can be freely adjusted to any intermediate value between the full-open value and the full-close value, such as a half-open value, a second-thirds open value or the like. Through the opening operation of the ventilation ports  48 , the outside air flowing into the outdoor-side chamber  22  is guided by the cabinet  19  to pass through the fine holes  51  of the ventilation shutter  49  and the ventilation ports  48  of the second top panel  42 , and then introduced into the outside introducing chamber  37 . 
     Here, the ventilation ports  48  are designed to be inclined downwardly to the outdoor-side chamber  22 , whereby the fluid flow area of the outside air between the second top panel  42  and the cabinet  19  is more greatly enlarged as compared with the case where the ventilation ports  48  are designed to be horizontal. Further, each of the fine holes  51  of the ventilation shutter shown in FIG. 6 is formed to have a remarkably smaller diameter than the opening area of the ventilation ports  48 , whereby the diameter of each fine hole  51  is set to such a value that it functions as an air filter to prevent invasion of insects, dust, etc. 
     The ventilation aeration portion  50 A is equipped with plural vent ports  50  at the lower portion of the indoor fan casing  34  as shown in FIG.  5 . The vent ports  50  are formed in a louver-shape so as to be juxtaposed with one another by cutting the lower portion of the indoor fan casing  34  into plural pieces and erecting the pieces thus achieved as shown in FIG. 5. A plurality of ventilation aeration portions  50 A as described above are formed in the longitudinal direction of the indoor fan casing  34  except for the position corresponding to the drain opening  44  of the partition plate  20 . 
     When the cross-flow fan  12  is rotated, the space below the cross-flow fan  12  in the indoor circulating chamber  36 , that is, the space in the neighborhood of the ventilation aeration portions  50 A is kept under negative pressure as shown in FIG.  3 . Therefore, as indicated by arrows C of FIG. 3, the outside air introduced through the fine holes  51  of the ventilation shutter  49  and the ventilation ports  48  of the second top panel  42  into the outside air introducing chamber  37  downwardly flows along the outside of the curved indoor fan casing  34 , passes through the aeration ports  50  of the plural ventilation aeration portions  50 A and then is guided into the indoor circulating chamber  36 . 
     The outside air thus guided into the indoor circulating chamber  36  is mixed with the indoor air air-conditioned by the indoor heat exchanger  11 , and introduced from the blow-out grille  43  of the front panel  18  into the room of the building, whereby fresh air is supplied into the room. 
     As shown in FIG. 5, an operating lever  54  is integrally linked to one end portion of the ventilation shutter  49 . The operating lever  54  is disposed so as to extend to the indoor heat exchanger  11  as shown in FIGS. 2 and 6 so that it can be manipulated when the front panel  18  is detached from the main body of the air conditioner or the like. By manipulating the operating lever horizontally, the ventilation shutter  40  is directly slid to any position with no wire, whereby the opening degree of the ventilation ports  48  can be adjusted to any value such as the full-open value, the full-close value, the half-open value, etc. 
     As shown in FIGS. 2 and 7, the electrical equipment mount device  45  shown in FIGS. 2 and 4 comprises a board accommodating case  57  having the control board  56  disposed at the inside thereof, an operation box  58  having operating thumbscrews for adjusting the temperature and the air flow rate, and a wire fixing structure for fixing electrical wires  60  (see FIGS. 8A and 8B and FIGS. 9A and 9B) connected to the control board  56 . 
     The operation box  58  is fixed to the upper portion of the board accommodating case  57 . A cooling/heating temperature adjusting thumbscrew (operating switch)  61  and a cooled/heated air flow rate adjusting thumbscrew  62  (operating switch) shown in FIG. 2 are mounted on the operation box  58 . A display plate  101  is interposed between the operation box  58  and each of the cooling/heating temperature adjusting thumbscrew  61  and the cooling/heating air flow rate adjusting thumbscrew  62 . The display plate  69 , the cooling/heating temperature adjusting thumbscrew  61  and the cooled/heated air flow rate adjusting thumbscrew  62  can be viewed when an operation door  63  of the front panel  18  is opened. 
     The control board  56  shown in FIG. 7 has various kinds of electronic parts such as transistors, capacitors, etc. mounted thereon, and the cross-flow fan  12 , the propeller fan  14 , the compressor  15 , etc. are controlled on the basis of set values which are set by the cooling/heating temperature adjusting thumbscrew  61  and the cooled/heated air flow rate adjusting thumbscrew  62 . A power supply circuit (not shown) is equipped on the control board  56 , and electrical wires  60  (shown in FIGS. 8A to  9 B) such as power supply wires, etc. are connected to the power supply circuit through a terminal board (not shown). 
     The wire fixing structure  59  shown in FIG. 7 serves to fix the electrical wires  60  (FIGS. 8A to  9 B) to a front plate  64  serving as a wire fixing face of the board accommodating case  57  by a fixing member  65  (such as a press member or the like). The wire diameter of the electrical wire  60  to be used is varied in accordance with the magnitude of power to be supplied t the power supply circuit of the control board  56 . For example, when power of 200V is supplied to the power supply circuit, the wire diameter of electrical wires  60  to be used is set to be larger than that when power of 100V is supplied to the power supply circuit. 
     As shown in FIG. 7, plural abutting portions  66  which can abut against the electrical wires  60  and are different in height are formed in the front plate  64  to which the electrical wires  60  are fixed. The abutting portion  66  comprises an abutting recess portion  67  that is formed to be recessed with respect to the front plate  64 , and an abutting flat portion  68  that is formed on the same plane as the front plate  64 . The abutting recess portion  67  is used to fix a thick electrical wire  60  (FIGS. 8A and 8B) having a large wire diameter, and the abutting flat portion  68  is used to fix a thin electrical wire having a small wire diameter (FIGS.  9 A and  9 B). 
     The press member  65  comprises a U-shaped press body  69  and flanges  70  and  71  which are formed integrally with the U-shaped press body  69  at both the ends of the U-shaped press body  69  as shown in FIGS. 7 to  9 B, and a press portion  75  is formed on the inner surface of the press body  69  so as to expand outwardly. The flange  70  of the press member  65  is designed to be engagedly fitted in an engaging hole  72  formed one side of the abutting recess portion  67  (abutting flat portion  68 ) of the front plate  64 . The flange  71  of the press member  65  can be fixed to front plate  64  by using fixing screw  74  which is threadedly engageable with a screw hole formed at the other end side of the abutting recess portion  67  (abutting flat portion  68 ) of the front plate  64 . 
     As shown in FIG. 8A, when the wire diameter of the electrical wire  60  is large, the electrical wire  60  is positioned between the abutting recess portion  67  of the front plate  64  and the press member  65 , the flange  70  of the press member  65  is engagedly inserted into the engaging hole  72  at one side of the abutting recess portion  67 , and then the flange  71  of the press member  65  is fixed to the front plate  64  by using the fixing screw  74  which is threadedly engaged with the screw hole  73  at the other side of the abutting recess portion  67 . The electrical wire  60  having a large wire diameter is fixedly mounted on the front plate  64  with being pinched between the abutting recess portion  67  and the press portion  75  of the press member  65  as shown in FIG. 8B by the press member  65  fixed to the front plate  64  as described above. 
     Further, as shown in FIG. 9A, when the wire diameter of the electrical wire  60  is small, the electrical wire  60  is positioned between the abutting flat portion  68  of the front plate  64  and the press member  65 , the flange  70  of the press member  65  is engagedly inserted in the engaging hole  72  at one side of the abutting flat portion  68 , and then the flange  71  of the press member  65  is fixed to the front plate  64  by using the fixing screw  74  which is threadedly engaged with the screw hole  73  at the other side of the abutting flat portion  68 . As described above, the electrical wire  60  having a small wire diameter is fixedly mounted on the front plate  64  with being pinched between the abutting flat portion  68  and the press portion  75  of the press member  65  as shown in FIG. 9B by the press member  65  fixed to the front plate  64  as described above. 
     The distance L between the press portion  75  of the press member  65  and the abutting recess portion  67  and the distance M between the press portion  75  of the press member  65  and the abutting flat portion  68  when the press member  65  is fixed to the front plate  64  are set to such values that pinching force enough to prevent the electrical wire  60  from falling off the front plate  64  can be applied to the electrical wire  60  when the electrical wire is pinched between the press portion  75  of the press member and the abutting recess portion  67  (the abutting flat portion  68 ). 
     Accordingly, according to this embodiment, the following effects can be achieved. 
     The plural abutting portions  66  that can abut against the electrical wires  60  and are different in height (that is, the abutting recess portion  67  and the abutting flat portion  68 ) are formed on the front plate  64  of the board accommodating case  57  of the electrical equipment amount device, and the electrical wire  60  is pinched by the press member  65  and one of the abutting recess portion  67  and the abutting flat portion  68  to fix the electrical wire  60  concerned to the front plate  64 . Therefore, one of the abutting recess portion  67  and the abutting flat portion  68  of the front plate  64  is selected in accordance with the wire diameter of the electrical wire  60 , and the electrical wire  60  can be fixed by the press member  65  and the selected one of the abutting recess portion  67  and the abutting flat portion  68 , so that the press member  65  can be commonly used among plural kinds of electrical wires  60 . Accordingly, it is unnecessary to prepare for plural kinds of press members  65  in accordance with the wire diameter of electrical wires  60 , so that the number of parts of the electrical wires  60  can be reduced and the manufacturing cost can be reduced. 
     The present invention is not limited to the above embodiment, and various modifications may be made without departing from the subject matter of the present invention. 
     For example, in the above embodiment, the depth of the abutting recess portion is set to a specific one in accordance with the wire diameter of an electrical wire to be fixed. However, the depth of the abutting recess portion is not limited to a specific one, and it may be designed to be freely variable in accordance with the wire diameter of an electrical wire to be fixed. 
     Further, in the above embodiment, the abutting recess portion  67  and the abutting flat portion  68  are formed on the front plate  64  of the board accommodating case  57  of the electrical equipment mount device  45 . However, when an electrical wire  60  having a smaller wire diameter is fixed, an abutting projecting portion which expands outwardly from the front plate  64  may be formed on the front panel in place of or together with the abutting flat portion  68  so that the electrical wire  60  is fixedly pinched between the abutting projecting portion and the press member  65 . In this case, the height of the abutting projecting portion may be designed to be freely variable in accordance with the wire diameter of an electrical wire to be fixed. 
     Still further, the number of abutting recess portions (abutting projecting portions) and abutting flat portions are not limited to a specific numeral, and it may be freely set to any numeral. 
     Still further, in the above embodiment, the present invention is applied to the electrical equipment mount device applied to the air conditioner, however, the present invention may be applied to electrical equipment mount devices for various kinds of equipment such as a showcase in which articles of food, etc. are put on show while refrigerated, an automatic vending machine, etc. 
     Still further, in the above embodiment, the wires to be fixed are electrical wires however, the wires may be communication wires such as telephone wires, etc. 
     FIG. 10 shows another embodiment of the electrical equipment mount device according to the present invention.

Here, the back-side edge of the bottom plate means an edge of the bottom plate that is located at the outdoor-side chamber side. likewise, the front-side edge means an edge that is located at the indoor-side chamber side. Accordingly, the back-side edge in FIG. 3 is located at the right side of FIG. 3, and the front-side edge in FIG. 3 is located at the left side of FIG.  3 . 
     The operation box  58  is fixed to the upper portion of the front plate portion  163  at the back sides of the side plates  272 B and  272 C thereof by using a fixing member as described later. The side plate portion  165  has a slope portion at the upper portion of the front side thereof, and the slope portion is forwardly inclined from the back side to the front side thereof The top plate portion  166  is designed in a rectangular shape so that the front and back sides thereof are slightly shorter in length than the upper side of the front plate portion  163  and the right and left sides thereof are equal to the slope portion (side) of the side plate portion  165  in length. Accordingly, the top surface of the electrical equipment mount box  157  is designed to have a forwardly-and-downwardly-inclined slope surface at the front side thereof and an opening portion at the back side thereof. 
     The above operation box  58  and the electrical equipment mount box  157  are inserted into the electrical equipment chamber  46  from the front side of the indoor-side chamber  21 , and fixed to the partition plate  20 . 
     FIG. 11 is a perspective view showing the electrical equipment mount device  145  to which a conduit fixing member is attached, and FIG. 12 is an exploded perspective view of the electrical equipment mount device  145  shown in FIG.  11 . 
     As shown in FIGS. 11 and 12, electrical wires  71  for supplying power to the cross-flow fan  12 , the propeller fan  14 , the compressor  15 , etc. are inserted in a conduit  160  shown in FIGS. 10 and 11 to be protected from the external force. The conduit  160  is used particularly when high voltage (for example, 265V or more) is applied to the electrical wires  71 . The conduit  160  is fixed by inserting a hollow fixing bolt  179  into one end portion of a conduit tube  178 , and the electrical wires  171  are inserted in the conduit tube  178  and the fixing bolt  179 . A fixing nut  180  is threadedly engageable with a screw portion  179 B of the fixing bolt  179 . 
     A conduit fixing plate  159  is fixed to the outer surface of the front plate portion  163  of the electrical equipment mount box  157  as described later, and it has a fixing face  172  to which one end portion of the conduit  160  is fixed. The electrical wires  171  in the conduit  160  fixed to the fixing face  172  of the conduit fixing plate  159  is connected to the terminals of the terminal table  173  mounted on the outer surface of the front plate portion  163  of the electrical equipment mount box  157 , whereby the electrical wires  171  are electrically connected to wires  174  which extend from the control board  156  and are connected to the other terminals of the terminal table  173 . 
     The cover  162  is designed in a box-like shape which is opened at the lower surface portion and the back surface portion thereof. The cover  162  is disposed so that the opening edge (peripheral edge)  175  of the lower surface portion thereof is brought into contact with the conduit fixing plate  159  and the opening portion of the lower surface portion is closed by the conduit fixing plate  159 . Further, the cover  162  is also disposed so that the opening edge (peripheral edge)  176  of the back surface portion thereof is brought into contact with the front plate portion  163  of the electrical equipment mount box  157  and the opening portion of the back surface portion is closed by the front plate portion  163 . In addition, the cover  162  is fixed to the top plate portion  166  of the electrical equipment mount box  157  by a screw  177 . Accordingly, the terminal table  173 , the electrical wires  171  and the wires  174  are accommodated in the cover  162  and protected from the external force. Under the cover-fixed state, the opening edge  175  of the lower surface portion of the cover  162  is fixed between a front flange portion  183  and a first side flange portion  181  to thereby prevent falling-off from the lower portion of the cover  162 . 
     The conduit fixing plate  159  comprises the front flange portion  183  at the front side of the fixing face  172 , a back flange portion  184  at the back side thereof, the first side flange portion  181  at one side thereof and a second side flange portion  182  at the other side thereof, the flange portions being bent substantially vertically to be continuos with on each other. 
     A conduit fixing hole  193  through which a screw portion  179 B of the fixing bolt  179  of the conduit  160  is inserted is formed in the fixing face  172  of the conduit fixing plate  159  by burring, for example. Under the state that the screw portion  179 B is inserted in the conduit fixing hole  193  of the fixing face  172 , the head portion  179 A of the fixing bolt  179  comes into contact with the lower surface of the fixing face  172 . 
     The first side flange portion  181  and the second side flange portion  182  which are disposed so as to face each other are bent in the opposite directions. For example, as shown in FIG. 13, the first side flange portion  181  is bent in the upward direction and the second side flange portion  182  is downwardly bent. As shown in FIG. 14, engaging hooks  185  and  186  as fixing members are integrally formed with the first side flange portion  181  and the second side flange portion  182  respectively at the back flange portion ( 184 ) side. Accordingly, the engaging hook  185  and the engaging hook  186  are located at the opposite sides with respect to the fixing face  172 , that is, the engaging hooks  185  and  186  are located at the upper and lower sides with respect to the fixing face  172 , respectively. Reference numeral L in FIG. 14 represents the difference in height in the vertical direction between the engaging hooks  185  and  186 . The engaging hooks  185  and  186  are hooked to hook holes  187  and  188  serving as fixing holes formed in the front plate portion  163  of the electrical equipment mount box  157 , respectively. Accordingly, the hook holes  187  and  188  are located at different positions in the vertical direction, and the difference in height in the vertical direction therebetween is substantially equal to that between the engaging hooks  185  and  186 . 
     As described above, the engaging hooks  185  and  186  of the conduit fixing plate  159  and the hook holes  187  and  188  of the electrical equipment mount box  157  are designed to have the difference L in height in the vertical direction. Therefore, as shown in FIG. 13, the conduit fixing plate  159  can keep rigidity to the force F acting in the vertical direction to the fixing face  172  or the moment M (torque) acting around the straight line extending in the direction from the front flange portion  183  to the back flange portion  184 . 
     Further, as shown in FIGS. 11 and 12, a screw hole  189  is formed in the back flange portion  184  of the conduit fixing plate  159 . After the engaging hooks  185  and  186  of the conduit fixing plate  159  are engagedly fitted in the hook holes  187  and  188  of the front plate portion  163  of the electrical equipment mount box  157 , a fixing screw  190  is inserted into the screw hole  189  of the back flange portion  184  of the conduit fixing plate  159  and threadedly engaged with the front plate portion  163  of the electrical equipment mount box  157 , whereby the conduit fixing plate  159  is fixed to the front plate portion  163  of the electrical equipment mount box  157 . Reference numerals  191  and  192  of FIGS. 7 and 8 represent auxiliary screw holes. 
     Next, the fixing work of the conduit  60  will be described. 
     First, the engaging hooks  185  and  186  of the conduit fixing plate  159  are fixedly fitted in the hook holes  187  and  188  of the front plate portion  163  of the electrical equipment mount box  157  and the fixing screw  190  is inserted in the screw hole  189  of the back flange portion  184  of the conduit fixing plate  159  to fix the back flange portion  184  to the front plate portion  163 , thereby fixing the conduit fixing plate  159  to the electrical equipment mount box  157 . 
     Subsequently, the screw portion  179 B of the fixing bolt  179  of the conduit  160  is inserted in the conduit fixing hole  193  formed in the fixing face  172  of the conduit fixing plate  159 , and the fixing nut  180  is threadedly engaged with the screw portion of the fixing bolt  179  projecting upwardly from the fixing face  172 . 
     At this time, as shown in FIG. 12, a fastening instrument  194  such as a spanner, a monkey wrench or the like is inserted from the let side of the conduit fixing plate  159  at which the first side flange portion  181  is equipped, and the fastening instrument  194  is fitted to the head portion  179 A of the fixing bolt  179  of the conduit  160 . Further, another fastening instrument  195  is inserted from the right side at which the second side flange portion  182 , and the fastening instrument  195  is fitted to the fixing nut  180  of the conduit  160 . Thereafter, the fixing face  172  of the conduit fixing plate  159  is clamped between the head portion  179 A of the fixing bolt  179  of the conduit  160  and the fixing nut  180  by using the fastening instruments  194  and  195 , thereby fixing the conduit  160  to the fixing face  172 . 
     As described above, under the state that the conduit  160  is fixed to the conduit fixing plate  159 , the electrical wires  71  in the conduit  160  are bundled and connected to the terminals of the terminal table  173 , and the wires  174  of the control board  156  and the electrical wires  171  in the conduit  160  are electrically connected to one another through the terminal table  173 . 
     Thereafter, the cover  162  is positioned so that the opening edge  175  of the lower surface portion and the opening edge  176  of the back surface portion thereof are brought into contact with the fixing face  172  of the conduit fixing plate  159  and the front plate portion  163  of the electrical equipment mount box  157 , whereby the terminal table  173 , the electrical wires  171  and the wires  174  are accommodated in the cover  162 . Thereafter, the cover  162  is fixed to the electrical equipment mount box  157  by using the screw  177 . 
     According to the above-described embodiment using the electrical equipment mount device thus constructed, the following effects (1) to (3) can be achieved. 
     (1) The engaging hooks  185  and  186  which are engagedly fitted in the hook holes  187  and  188  of the front plate portion  163  of the electrical equipment mount box  157  are equipped at different positions (upper and lower positions) with respect to the fixing face  172  to which one end portion of the conduit  160  is fixed. Therefore, the conduit fixing plate  159  has high rigidity to the force acting from the conduit  160 , and the mechanical strength thereof is enhanced, so that the conduit fixing plate  159  can be designed in a compact size. 
     (2) The engaging hooks  185  and  186  of the conduit fixing plate  159  are engagedly fitted in the hook holes  187  and  188  of the front plate portion  163  of the electrical equipment mount box  157 , whereby the conduit fixing plate  159  can be fixed to the electrical equipment mount box  157 . Therefore, the fixing workability of the conduit fixing plate  159  can be enhanced, and the number of fixing screws  190  for fixing the conduit fixing plate  159  to the electrical equipment mount box  157  can be reduced, so that the manufacturing cost can be reduced. 
     (3) The conduit fixing plate  159  is equipped with the first side flange portion  181  and the second side flange portion  182  which are bent in the opposite directions and formed at the opposite positions with respect to the fixing face  172 . Therefore, even when the fastening members  194  and  195  such as spanners or the like are inserted to the upper and lower sides of the fixing face  172  to fasten the fixing nut  180  in order to fix one end portion of the conduit  160  to the fixing face  172  with the fixing nut  180 , the fastening instruments  194  and  195  can prevented from interfering with the first side flange portion  181  and the second side flange portion  182  of the conduit fixing plate  159 . Therefore, the fastening work of fixing one end portion of the conduit  160  can be easily performed. 
     The present invention is not limited to the above embodiment, and various modifications may be made without departing from the subject matter of the present invention. 
     For example, in the above embodiment, two engaging hooks (the engaging hooks  159  and the  186 ) are formed on the conduit fixing plate  159 . However, the number of the engaging hooks is not limited to two, and three or more engaging hooks may be equipped to the conduit fixing plate  159 . In this case, it is necessary that at least one engaging hook is formed at an upper or lower position different from the position of another engaging hook with respect to the fixing face  172 . 
     According to the electrical equipment mount device of this embodiment, the conduit fixing member for fixing the end portion of the conduit for electrical wires can be miniaturized. Further, the fixing workability of the conduit fixing member can be enhanced and the manufacturing cost can be reduced. 
     FIG. 15 is a cross-sectional view showing the arrangement of the operation box  58  and the electrical equipment mount box  157  in the main body of the air conditioner when they are viewed from the right side of the main body. In FIG. 15, the cover  172 , the conduit fixing plate  162 , etc. are omitted from the illustration. It is needless to say that this embodiment has the same effect even when these elements are provided. 
     The collar portion  272 E of the operation box  58  is fit to the inner surface of the bent front edge portion  41 A of the first top panel  41  of the partition plate  20 , and then fixed to the front edge portion  41 A by a fixing member such as a screw or the like to thereby fix the operation box (electrical equipment mount box) to the partition plate  20 . Therefore, there occurs no gap at the joint portion between the upper portion of the operation box  58  and the first top panel  41 , thereby preventing invasion of liquid such as drinking water or the like through the joint portion into the inside of the first top panel  41 . 
     In this case, even when a circuit board  76  is mounted on the inner surface of the top plate  272 D of the operation box  58  as shown in FIG. 15, invasion of driving water or the like into the circuit board  76  through the joint portion can be also prevented. the operation box  58  is disposed substantially beneath the operation door  63  of the front panel  18 . 
     Seal (not shown) is applied to the peripheral portions of the holes  272 F formed in the top plate  272 D of the operation box  58 . When drinking water or the like is applied to the display plate  101  or the thumbscrews  61  and  62 , the seal can prevent invasion of drinking water or the like from the display plate  101  or the thumbscrews  61  and  62  through the holes  101 A and  101 B of the display plate  101  and the holes  272 F of the operating box  58  into the operating box  58 . 
     In this embodiment, the electrical equipment mount box  157  is fixedly mounted at the space surrounded by the right plate  20 A and the back plate  20 C of the partition plate  20  (FIG. 5) and thus it is embedded inside the partition plate  20 . The right edge of the electrical equipment mount box  157  is superposed on the side edge of the right plate  20 A at the indoor-side chamber ( 21 ) side and fixed to the side edge of the right plate  20 A at plural positions by screws (not shown). 
     As described above, the control board  56  is mounted inside the electrical equipment mount box  157  as shown in FIG.  15 . The control board  56  is fixedly mounted between the bottom plate  164  and the top plate  166  of the electrical equipment mount box  157  in parallel to the front plate portion  163  so as to be spaced from the front plate portion  163  toward the outdoor-side chamber ( 22 ) side at a distance of about 5 mm, for example. 
     Accordingly, even when liquid such as drinking water or the like invades into the electrical equipment mount box  157  as indicated by an arrow F in FIG. 15, the liquid flows downwardly along the slope portion of the top plate portion  166  and then along the front surface of the front plate portion  163  on which the operation box  58  is mounted. The control board  56  is mounted on the back surface of the front plate portion  163  which is located at the opposite side to the front surface, and thus the liquid can be prevented from invading into the control board  56 . Therefore, electrical parts mounted on the control board  56  can be protected from liquid such as driving water or the like. 
     According to the arrangement of the operation box  58  and the electrical equipment mount box  157  as described above, the electrical equipment mount box  157  is disposed inside the partition plate  20  and located in an area extending outwardly (backwardly) from the outside edge (nearer to the outdoor-side chamber  22 ) of the opening portion  65  of the front panel  18 . Further, the second top plate  42  is located substantially beneath the joint portion  80  between the front panel  18  and the cabinet  19 . Therefore, the control board  56  mounted in the electrical equipment mount box  157  can be surely protected from liquid such as driving water or the like. 
     When a glass containing liquid such as driving water or the like is put on the front panel  18  or the cabinet  19  and carelessly turned over and thus it invades through the edge of the operation door  63  disposed on the opening portion  65  into the inside of the operation door  63  as indicated by arrows A or B in FIG. 15, the inside of the operation box  58  and the inside of the electrical equipment mount box  157  are protected from the liquid as described below. 
     When liquid drops in the direction indicated by the arrow A, it drops onto the slope upper surface of the operation box  58  or the display plate  101 , flows along the slope upper surface and front surface of the operation box  58  or the display plate as indicated by the arrow D of FIG. 15, and finally drops onto the bottom plate  16 . Therefore, the liquid dropped in the direction of the arrow A can be prevented from invading into the inside of the operation box  58  and the inside of the electrical equipment mount box  157 . 
     When liquid drops in the direction indicated by the arrow B, it drops through the joint portion  80  between the front panel  18  and the cabinet  19  onto the second top plate  42 , flows along the sloped second top plate  42  and the back surface (at the outdoor-side chamber side) of the partition plate  20  and finally drops onto the bottom plate  16  as indicated by an arrow E. Further, fixing holes  81  for fixing the first top plate  41  and the second top plate  42  exist substantially beneath the joint portion between the front panel  18  and the cabinet  19  as shown in FIGS. 5 and 14, and the top plate  166  of the electrical equipment mount box  157  is located substantially beneath the fixing holes  81 . Therefore, the liquid dropping through the joint portion  80  between the front panel  18  and the cabinet  19  also flows through the fixing holes  81  into the inside of the partition plate  20  as indicated by an arrow F of FIG.  15 . In this case, the liquid drops onto the top plate  166 , flows downwardly along the slope portion of the top plate  166  and along the front surface of the front plate portion  163  on which the operation box  58  is mounted, and then finally drops onto the bottom plate  16 . Therefore, the liquid can be prevented from invading into the inside of the electrical equipment mount box  157 , and thus the control board  56  (electrical parts) can be protected from the liquid. 
     Here, as shown in FIG. 15, the back-side edge of the top plate (slope portion)  166  of the top plate is located so as to slightly extend to the outdoor-side chamber side as compared with the front-side edge of the second top plate  42 . Therefore, the liquid drops through the fixing holes  81  surely drops on the slope portion of the top plate  166 , and flows downwardly along the slope portion of the top plate  166  in the direction of the arrow F. 
     Accordingly, no liquid invades into the inside of the electrical equipment mount box  157 , and the control board (the electrical equipment) can be protected. In addition, by shortening the length of the top plate  166 , the manufacturing cost of the electrical equipment mount box  157  can be reduced. 
     Further, the electrical equipment mount box  157  is fixed to the inner surface of the right plate  20 A of the partition plate  20 , and the back surface and the right surface (plate) of the electrical equipment mount box  157  are covered by the partition plate  20 . Therefore, the electrical equipment mount box  157  is fully covered substantially at all the surfaces thereof like a dosed box although it is not designed as a closed box. Accordingly, the manufacturing cost can be reduced as compared with a fully-closed box type electrical equipment mount box. 
     According to the above-described embodiment, there can be achieved the effect that liquid such as driving water or the like invading through the opening port is prevented from invading into the inside of the operation box and the electrical equipment mount box, so that the electrical parts can be protected from liquid.
