[Industrial applications]

 The present invention relates to an indoor unit of an air conditioner, and more particularly, to a motor mounting means of a cross flow fan that sends out heat-exchanged air to the room.

[0002]

[Prior art]

 A housing of an indoor unit of an air conditioner includes, for example, a base (also referred to as a main body) 2 as shown in FIG. 1, a front panel 3 detachably attached to the base 2, and a front panel 3 in front of the front panel 3. It is composed of a suction grill 4 to be mounted, suction ports 5a and 5b for taking in the air in the room are provided in the upper part of the housing 1, and heat-exchanged air is sent to the room in the lower front part. A blow-out port 6 for forming is formed. In the air passage 7 that connects the suction ports 5a, 5b and the air outlet 6, an air filter 8 that is removable along the filter guide 3a that is integrally formed with the front panel 3, a heat exchanger 9, A crossflow fan (blower) 10 for sending out the heat-exchanged air to the outlet 6 is arranged, and a motor 11 of the crossflow fan 10 has a bearing portion thereof with a vibration-proof rubber 12 interposed between the casing 13 and a predetermined casing 13. The casing 13 is fixed in a predetermined position of the base 2.

[0003]

[Problems to be solved by the device]

 By the way, as the indoor unit has become smaller, the mounting space for the motor 11 has become smaller. On the other hand, since lead wires are coming out of the motor 11, it is necessary to give sufficient consideration to the mounting direction of the motor 11, and accurate positioning must be performed, but the motor 11 and the casing 13 are partially In the case of a structure in which they are in direct contact with each other, vibration on the side of the motor 11 may be transmitted to the casing 13 and further transmitted to the base 2 to generate noise. Therefore, it is an object of the present invention to provide an indoor unit of an air conditioner which is capable of accurately and easily positioning the motor 11 and which does not generate noise.

[0004]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems, and includes an air filter that is detachably attached to an air passage that connects a suction port at the upper part of the housing and an air outlet at the lower part of the housing, and a heat exchanger. A cross flow fan or the like for sending out the heat-exchanged air to the outlet is provided, the motor of the cross flow fan is housed in a predetermined casing, and the casing is locked to a base at the rear of the housing. In an indoor unit of an air conditioner, a positioning first convex portion is provided on the outer periphery of the motor, and a second convex portion corresponding to the first convex portion is provided inside the casing so as to be retractable. The second convex portion is retracted when the casing is locked at a predetermined position of the base.

[0005]

[Action]

 With the above configuration, the motor has the first convex portion necessary for positioning the motor on the outer periphery, and the casing for housing the motor has the second convex portion corresponding to the first convex portion on the motor side. Since the motor is positioned by aligning these with each other, the motor can be positioned, and the second convex portion is provided so as to be retractable. When the casing is locked at a predetermined position of the base, the second convex portion is formed. Since it is set back, the contact between the first and second protrusions can be eliminated, and only the anti-vibration rubber is interposed between the motor and the casing, so noise caused by vibration on the motor side can be eliminated. Can be prevented.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows the inside and outside of an indoor unit. This housing 1 is a base 2, a front panel 3 which is detachably attached to the base 2, and a suction grill 4 which is mounted in front of the front panel 3. It consists of and. Suction ports 5a and 5b for indoor air are provided in the upper part of the housing 1, and an air outlet 6 is formed in the lower part of the front surface. An air passage 7 is formed between the suction ports 5a, 5b and the air outlet 6, and the base 2 is provided in the air passage 7 along the front surface of the filter guide 3a integrally formed with the front panel 3. A detachable air filter 8 that can be moved to the side, a heat exchanger 9, and a cross flow fan 10 are arranged, and the air that has undergone heat exchange by the heat exchanger 9 is blown out by the cross flow fan 10. 6, the wind direction into the room is adjusted by a wind direction plate (not shown). The motor 11 of the cross flow fan 10 is housed in a predetermined casing 13 via a vibration-proof rubber 12 in its bearing portion, and the casing 13 is attached to a predetermined position of the base 2.

By the way, since the lead wire 14 extends from the motor 11, it is necessary to position the motor 11 when the motor 11 is housed in the casing 13. Therefore, in the present embodiment, as shown in FIG. 2, a convex portion (first convex portion) 15 is provided on the outer periphery of the motor 11 and a convex portion (first convex portion) corresponding to the convex portion 15 is formed inside the casing 13. The second convex portion 16 is provided, and the motor 11 is positioned by bringing them into contact with each other. However, if the protrusions 15 and 16 are left in contact with each other, the vibration on the motor 11 side is transmitted to the casing 13, and may be transmitted to the base 2 to generate noise, so that the protrusion 16 can be projected and retracted. When the positioning of the motor 11 is completed, the convex portion 16 is retracted and separated from the convex portion 15. Reference numeral 17 is a claw portion integrally formed on the front surface of the base 2 for retracting the convex portion 16. In order to retract the convex portion 16, the casing 13 may be brought into contact with the base 2 and raised in the direction of the arrow.

3A and 3B show a procedure for positioning the motor 11. First, as shown in FIG. 3A, the convex portion 15 on the motor 11 side and the convex portion 16 on the casing 13 side are formed. And abut. Next, as shown in (b), the inner wall of the casing 13 is raised while abutting against the inner side of the claw portion 17. At this time, the left and right sides of the convex portion 16 are pushed by the claw portions 17, and the convex portion 16 retracts. Even if the convex portion 16 retreats in this manner, the vibration isolating rubber 12 is attached to the bearing portion 18 of the motor 11, and the peripheral edge of the antivibration rubber 12 has elasticity and contacts the casing 13 side. Therefore, the position of the motor 11 is not displaced. The claw portion 17 is for retracting the convex portion 16 and does not fix the casing 13 itself. Further, the formation of the convex portion 16 is not limited to the casing 13 side. For example, as shown in FIG. 4, the convex portion 16 is integrally provided on the base 2 side, and the motor 11 is also attached to the base 2 side. The protrusion 16 may be retracted in the direction of the arrow by raising it to the position of the broken line.

[0009]

[Effect of device]

 With the configuration described above, the motor can be positioned accurately and easily, and after the motor is positioned, the position used for the positioning is separated from the motor side. Therefore, the vibration on the motor side is not transmitted to the housing side, and there is no risk of noise.
