Here, the suction inlet 100 is an edge data (not shown) that is rotated by integrally attaching a brush extending in a spiral over the entire length on the outer peripheral circumference so as to effectively suck dust on the bottom surface when dust collecting, and A motor (not shown) embedded as a driving means separate from the motor mounted in the main body 200 to rotate the edge data at high speed, and the drive shaft and the edge data of the motor to transfer the driving force of the motor to the edge data. And a belt (not shown), which is a kind of power transmission means installed on the rotating shaft of the motor.

In addition, two transfer wheels 110 are mounted on both rear sides of the suction inlet 100 to exert cloud friction with the bottom surface to freely move the suction inlet 100 during cleaning.

In addition, the main body 200 has a cover portion 210 mounted so as to artificially open the inside on the front side when viewed externally, and a handle portion extended while cutting on the upper end so as to be easily gripped by the worker during cleaning. 220, and an operation switch unit 230 in the lower portion of the handle portion 220 to selectively switch the power of the vacuum cleaner ON / OFF, and also to adjust the size of the vacuum suction input. have.

As shown in FIG. 2, the main body 200 includes a cover 210, a midbody 240, and a base body 250, wherein the cover 210 and the midbody 240 are formed. A dust bag (not shown) is installed in the dust collecting chamber 242 to collect and store foreign substances such as dust collected from the suction port 100 in one place, and the mid body 240 and the base body 250 are installed. The motor case 260, which includes a motor (not shown) mounted to generate a vacuum suction input applied to the suction inlet 100 when dust is collected on the motor accommodating part 244, which is formed by A cord reel (not shown) for elastically winding a cord for supplying power to a motor is accommodated in the cord receptacle 246 formed by the body 240 and the base body 250.

In addition, a suction grill 247 is formed at a lower portion of the dust collecting chamber 242 of the midbody 240 to communicate with the motor accommodating portion 244, and communicates with the outside as a lower front portion of the midbody 240. Exhaust grill 248 is formed, and the motor case 260 is in communication with the exhaust grill 248 and the intake port 262 and the one side communicating with the suction grill 247 upwards, as shown in FIG. And an exhaust port 264 to be provided.

After air-cooled, and then sequentially passed through the exhaust port 264 and the exhaust grill 248 formed in the side is discharged to the outside.

However, the inlet 262 of the motor case 260 communicating with the suction grille 247 of the midbody 240 has a stepped portion 263 having a stepped shape in a stepped shape therein as shown in FIG. 4. The air flowing into the motor case 260 through the inlet 262 through the suction grille 247 forms a vortex while colliding with each other at the step 263 of the inlet 262 to generate vortex noise. There was a disadvantage that caused.

In addition, air discharged to the outside through the exhaust grill 248 through the exhaust port 264 of the motor case 260 is first introduced into the motor case 260 through the inlet 262. After that, the exhaust port 264 is first discharged to the outside of the motor case 260, and again the outer circumferential surface of the motor case 260 is formed along the space formed by the motor case 260 and the motor accommodating part 244. After turning, it is discharged to the outside through the exhaust grill 248. At this time, the air discharged through the exhaust port 264 of the motor case 260 collides with each other, causing noise.

The present invention has been devised to solve the above disadvantages, by changing the shape of the inlet and exhaust port of the motor case it is possible to reduce the noise by causing a smooth flow while preventing the collision of air flowing in and out through it The purpose is to provide an exhaust structure of an upright vacuum cleaner.
