An embodiment of the present invention relates to a suction motor mounting structure of a vacuum cleaner.

In general, a vacuum cleaner is a device that sucks air containing a foreign material by using a suction force generated by a suction motor mounted inside the main body, and then filters the foreign material inside the main body.

Such a vacuum cleaner includes a suction nozzle that sucks air containing foreign matter on the surface to be cleaned, a foreign material separating part that separates the foreign material from the air sucked by the suction nozzle, and a dust collecting device in which the foreign material stored in the foreign material separating part is stored. . Here, the foreign matter separating unit and the dust collecting device may be provided in the cleaner body.

The main body of the cleaner is provided with a motor chamber for accommodating the suction motor and a motor chamber cover provided at one side of the motor chamber to cover the suction motor.

The motor chamber may be coupled to an inner surface of the body, and the motor chamber cover may be firmly coupled to seal the inside of the motor chamber.

However, according to the conventional vacuum cleaner, the inside of the motor chamber is not sealed, and the phenomenon that the air flow passing through the suction motor leaks out.

In this case, there is a problem that the suction force of the suction motor is lowered, and dust inside the motor chamber is discharged to the outside. As a result, the dust separation performance of the cleaner is reduced and the environment around the cleaner is dirty, the problem appeared that the reliability of the product is lowered.

In order to solve the above problems, an embodiment of the present invention is to provide a vacuum cleaner to improve the structure of the cleaner to facilitate the sealing of the motor chamber.
