FIG.

  As shown in FIG. 1, the ventilator 10 according to the embodiment is installed on an indoor 40 side such as a wall 31 or a ceiling of a building, sucks air in the indoor 40, and exhausts it to the outdoors 41 through the ventilation pipe 32. The ventilator 10 is constructed by incorporating a blower 12 including a small motor 14 a and an impeller 13 in a main body casing 11.

  The main body casing 11 includes a flange portion 11a disposed on the indoor 40 side, an opening portion 11b for sucking air in the indoor 40, a wind tunnel portion 11c serving as an air passage, and an axial center direction extending from the wind tunnel portion 11c. Are provided with three main body mounting legs 11d (see FIG. 2) spaced in the circumferential direction for mounting the blower 12 to the main body casing 11 with screws 30a.

  As shown in FIGS. 2, 5, and 7, the motor case 15 includes a case attachment leg 15 a that is attached to the body attachment leg 11 d of the main body case 11, and a body attachment of the main body case 11 that is provided on the case attachment leg 15 a. A guide portion 15b for positioning the motor case 15 with the legs 11d sandwiched from both sides, a wiring space 15c (see FIG. 7) for accommodating the power supply wire 14d of the small motor 14a, and a claw portion 15d are provided. The small motor 14a is attached to and held in the motor case 15 by screws 30b (see FIG. 7).

  As shown in FIGS. 3, 6, and 8, the motor cover 16 includes a hooking portion 16a that engages with a claw portion 15d of the motor case 15, and is attached to the motor case 15 by the hooking portion 16a. Cover the back. The decorative panel 33 is attached to the wall 31 on the indoor 40 side so as to cover the flange portion 11 a of the main body housing 11.

  As shown in FIGS. 1 and 4, the impeller 13 of the blower 12 is attached to the shaft tip of the small motor 14 a and is arranged on the opening 11 b side formed on the indoor 40 side of the main body housing 11. The blower 12 sucks the air in the indoor 40 from the opening 11 b of the main body housing 11 and exhausts it to the outdoor 41 through the ventilation pipe 32, the outdoor opening 32 a and the outdoor hood 34.

  As shown in FIGS. 1 to 4, when the small motor 14 a is attached to the main body housing 11, a motor case 15 and a motor cover 16 are used. The motor case 15 can fix the small motor 14a with screws 30b, and is provided with a case mounting leg 15a that abuts on the tip of the main body mounting leg 11d of the main body housing 11, and the main body provided on the case mounting leg 15a. A guide portion 15b for positioning the motor case 15 with the main body mounting leg 11d of the housing 11 sandwiched from both sides, a wiring space 15c for accommodating the power supply wire 14d of the small motor 14a, and a claw portion 15d are provided.

  By housing the power supply wire 14d in the wiring space 15c provided in the motor case 15, it is possible to minimize a decrease in the amount of ventilation air due to the ventilation resistance of the power supply wire 14d.

  The motor cover 16 can be attached by hooking the hook portion 16a of the motor cover 16 on the claw portion 15d of the motor case 15 to which the small motor 14a is attached. In the wiring space 15c provided inside the motor case 15, It can be attached after the power supply wire 14d is accommodated, and assembly is easy.

  When the blower 12 is attached to the main body casing 11, the case mounting leg 15a of the motor case 15 is brought into contact with the main body mounting leg 11d of the main body casing 11, and the screw 30a is screwed into the screw hole 11e of the main body mounting leg 11d. Secure with. The screw hole 11e is a through screw hole, and the blower 12 can be attached to the main body attachment leg 11d of the main body housing 11 from the indoor 40 side or the outdoor 41 side (see FIGS. 2 to 4).

  As shown in FIGS. 1-3, when using the small motor 14a as a motor of the air blower 12, it installs from the indoor 40 side. When the blower 12 is attached to the main body mounting leg 11d of the main body housing 11 with the screw 30a from the indoor 40 side, the guide portion 15b is provided on the case mounting leg 15a of the motor case 15, so that the blower 12 is connected to the main body housing. It is difficult to come off the main body mounting leg 11d of the body 11, and the positioning and assembly of the blower 12 are easy.

  As shown in FIG. 9, when a motor 14b having an outer diameter larger than that of the small motor 14a is used as the motor of the blower 12, the motor casing 15 and the motor cover 16 are not used, and the housing flange of the motor 14b is attached to the body housing. The screw 30a is screwed through the respective attachment holes that are brought into contact with the main body mounting legs 11d of the body 11 and are provided in the through screw holes 11e of the main body mounting legs 11d so as to be spaced apart from each other in the circumferential direction of the flange. And fix it.

  As shown in FIG. 10, when the other motor 14c having a larger outer diameter and rear flange length than the small motor 14a is used as the motor of the blower 12, the motor case 15 and the motor cover 16 are not used. The flange of the housing of the motor 14c is brought into contact with the main body mounting leg 11d of the main body casing 11, and is provided in the through screw hole 11e of the main body mounting leg 11d so as to be spaced apart in the circumferential direction of the flange to match the through screw hole 11e. What is necessary is just to screw and fix the screw 30a through each attachment hole to perform.

  9 and 10, when the projecting dimension L of the blower 12 from the wind tunnel portion 11 c of the main body casing 11 to the outdoor 41 side projects from the wall 31 to the outdoor 41 side, the blower 12 is connected to the main body casing. The main body mounting leg 11d is attached from the indoor 40 side.

  By making the blower 12 attachable to the main body mounting leg 11d of the main body casing 11 not only from the outdoor 41 side but also from the indoor 40 side, and by using the small motor 14a, The projecting dimension L of the blower 12 from the wind tunnel portion 11c to the outdoor 41 side can be reduced, and there are many restrictions on the installation of the ventilator 10 such as during renovation (for example, the case where the wall thickness dimension of the building cannot be increased) The ventilator 10 can be installed even when the existing outdoor hood 34 is used to replace only the ventilator 10.

  As described above, the ventilating apparatus 10 according to the embodiment can mount the small motor 14a, the motor 14b, and the other motors 14c having different sizes on the main body mounting leg 11d of one type of main body casing 11. . Moreover, it is easy to assemble and can be installed even when there are many restrictions on the installation of the ventilation device 10 such as during renovation.

  As described above, the ventilator according to the present invention is useful as a ventilator installed at the time of renovation or the like.
