Description

  The present invention relates to an air conditioner.

  As the duct type air conditioner 100 in the air conditioner, for example, as shown in FIG. 4, there is one that is suspended by a hanging tool B <b> 1 or B <b> 2 between an indoor ceiling plate 80 </ b> A and a building ceiling wall 80 </ b> B. This duct type air conditioner 100 includes a hollow rectangular parallelepiped casing 10 made of sheet metal, an air inlet 11 is formed in a rear plate 10a of the casing 10, and an air outlet 12 is formed in a front plate 10b. Is formed. And in the air flow path 13 which connects the air suction inlet 11 and the air blower outlet 12, the heat exchanger 20 is arrange | positioned at the air blower outlet 12 side, and the ventilation fan 50 is arrange | positioned at the air suction inlet 11 side, respectively. Yes.

  5 and 6 show the internal configuration of the duct type air conditioner 100. FIG. The casing 10 is formed into a hollow rectangular parallelepiped shape by combining a casing 10A for a heat exchanger and a casing 10B for a blower fan with a partition plate 14 communicating with an air flow passage 13 interposed therebetween. Yes.

  The casing 10A for the heat exchanger is surrounded by a top plate 10A1 that forms the top surface, a bottom plate 10A2 that forms the bottom, a right side plate 10A3 that forms the right side, and a left side plate 10A4 that forms the left side. Has been. An air outlet 12 is formed in the housing 10A, and a heat exchanger 20 is disposed inside. And the heat insulating material 30 is arrange | positioned at the inner surface of the top | upper surface board 10A1 of the housing | casing 10A, and the drain pan 40 is arrange | positioned at the upper surface of bottom face board 10A2.

  A casing 10B for the blower fan is surrounded by a top plate 10B1 that forms a top surface, a bottom plate 10B2 that forms a bottom surface, a right side plate 10B3 that forms a right side, and a left side plate 10B4 that forms a left side. Has been. An air suction port 11 is formed in the housing 10B, and a blower fan 50 is disposed therein. As the blower fan 50, a sirocco fan having an impeller 52 that is rotationally driven by a motor 60 is used in a fan case 51, and air is sucked from the air suction port 11 and is then passed through the air flow passage 13. Blow out in 20 directions.

  By the way, the blower fan 50 of the duct type air conditioner 100 easily adheres dust to the vicinity of the impeller 52 and needs to be periodically cleaned, maintained, and inspected. At this time, the motor 60 needs to be removed. Since the duct type air conditioner 100 is relatively large and the motor 60 is also large and heavy, it is difficult to attach or remove it.

  Therefore, conventionally, a mechanism for temporarily fixing the motor 60 to the housing 10B is adopted so that the motor 60 can be temporarily fixed before being fixed or removed, thereby facilitating the attachment and removal. It has been broken.

  FIG. 7 is a view showing a motor mounting device 200 having a temporary fixing structure for the motor 60 (see, for example, Patent Document 1). Reference numeral 210 denotes a motor mounting body bent into a U-shape, and 220 and 230 denote motor clamping bands.

  The motor mounting body 210 includes motor support pieces 211 and 212 and connection pieces 213 that connect the motor support pieces 211 and 212 to each other. The motor support piece 211 fixes the curved recess 211 a that supports the boss portion 62 on one side of the motor 60, the engagement claw 211 b that engages the motor fastening band 220, and the motor fastening band 220. And a temporary fixing claw 211d formed so as to protrude outward from the fixing piece 211c. The motor support piece 212 also fixes a curved recess 212 a that supports the boss portion on the other side of the motor 60, an engagement claw 212 b that engages the motor fastening band 230, and a motor fastening band 230. It has a fixed piece 212c and a temporary fixing claw 212d formed so as to protrude outward from the fixed piece 212c. The connection piece 213 is provided with an attachment piece 213a for attaching the motor attachment body 210 to the top plate 10B1 of the housing 10B.

  The motor fastening band 220 includes a curved band portion 221, an engagement hole 222 that engages with an engagement claw 211 b of the motor attachment body 210, a fixed piece 223 that rides on a fixed piece 211 c of the motor support piece 211, A temporary fixing piece 224 formed by bending outward from the fixing piece 223 and a temporary fixing hole 225 formed in the temporary fixing piece 224 are provided.

  The motor fastening band 230 includes a curved band portion 231, an engagement hole 232 that engages with the engagement claw 212 b of the motor attachment body 210, a fixed piece 233 that rides on the fixed piece 212 c of the motor support piece 212, A temporary fixing piece 234 formed by bending outward from the fixing piece 233 and a temporary fixing hole 235 formed in the temporary fixing piece 234 are provided.

  As shown in FIG. 8, in the motor mounting device 200, the boss portions 62 on both sides from which the rotating shaft 61 of the motor 60 is drawn are brought into contact with the curved concave portions 211 a and 212 a of the motor support pieces 211 and 212 of the motor mounting body 210. .

  Then, after engaging the engagement hole 222 of the motor tightening band 220 with the engagement claw 211 b of the motor mounting body 210, the temporary fixing hole 225 of the motor tightening band 220 becomes the temporary fixing claw 211 d of the motor support piece 211. The temporary fixing piece 224 is temporarily fixed to the motor support piece 211 so as to engage with the motor.

  In addition, after engaging the engagement hole 232 of the motor tightening band 230 with the engagement claw 212 b of the motor attachment body 210, the temporary fixing hole 235 of the motor tightening band 230 becomes the temporary fixing claw 212 d of the motor support piece 212. Is temporarily fixed to the motor support piece 212.

  As a result, the motor 60 is temporarily fixed to the motor mounting device 200. Thereafter, the fixing piece 223 of the motor fastening band 220 is fixed to the fixing piece 211c of the motor support piece 211 with the screw C1, and the motor is fixed with the screw C2. If the fixing piece 233 of the fastening band 230 is fixed to the fixing piece 212 c of the motor support piece 212, the motor 60 is finally fixed to the motor mounting device 200. Thereafter, the motor attachment 210 may be screwed to the top plate 10B1 of the housing 10B.

  Thus, when the motor 60 is mounted, the motor 60 can be temporarily fixed to the motor mounting apparatus 200 and then fixed with the screws C1 and C2. Moreover, what is necessary is just to perform the reverse operation | work, when removing the motor 60. FIG. Therefore, the operation of attaching and detaching the motor 60 to the motor attachment device 200 is facilitated.
