Description

Vacuum cleaner {Vacuunm cleaner}

This embodiment relates to a vacuum cleaner.

The present embodiment relates to a vacuum cleaner, and more particularly, to a vacuum cleaner to improve the structure of the motor housing so that the suction force of the suction motor can be evenly applied to the motor inlet side.

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

Such a vacuum cleaner should be able to smoothly flow the air sucked from the suction nozzle inside the cleaner body, and the dust may be easily separated from the air including the dust. This is an important criterion for determining the performance of the vacuum cleaner.

To this end, it is common for the vacuum cleaner to be provided with a dust separation apparatus including a dust separation chamber. The dust separation device may be mounted inside the main body of the cleaner.

On the other hand, the vacuum cleaner may be provided with a plurality of filters to separate the dust from the air. In particular, in front of the suction motor, a filter may be provided that allows dust to be separated from the air entering the suction motor.

That is, air may be sucked into the suction motor through the filter.

In addition, in front of the suction motor, it is common to form an air inlet for allowing air to be sucked into the suction motor. The air inlet may be positioned adjacent to the filter.

On the other hand, according to the conventional vacuum cleaner, the air inlet is formed in any limited position in front of the inlet motor (inlet side), there is a problem that the suction force is excessively applied only to the filter portion located close to the air inlet.

In this case, a large amount of air passes around the filter portion in which the motor suction force is large, and thus, there is a problem in that dust accumulates in a predetermined portion of the filter.

Eventually, there is a problem that the suction performance of the motor is weakened and the life of the peeler is shortened.

The present embodiment aims to propose a vacuum cleaner in which the suction force of the suction motor is distributed and acted on the front surface of the filter.

To this end, it is an object of the present invention to propose a vacuum cleaner to be positioned in correspondence with the front surface of the filter formed in the motor housing.

According to another aspect of the present invention, a vacuum cleaner includes: a body forming an appearance; A suction motor provided in the main body, the suction motor generating a suction force; A motor housing configured to accommodate the suction motor therein and to form an air suction unit; And a filter member provided at the front of the motor housing to separate dust from the air, wherein the air suction part includes a first suction part formed at one side of the filter member and a size larger than that of the first suction part. The second suction part is formed small.

According to the embodiment of the above configuration, since a plurality of air intakes are formed in the motor housing, there is an advantage that the suction force of the motor can be distributed to the filter.

In addition, since air passes through the front surface of the filter, there is an effect that accumulation of dust does not occur in a predetermined portion of the filter.

As a result, the suction performance of the motor is improved, and the life of the filter is long.

4 to 6, the main body 10 according to an embodiment of the present invention includes a suction motor 130 for generating a suction force and a motor housing 100 for receiving the suction motor 130. do.

The suction motor 130 may be configured such that air is sucked from the front and discharged to the side.

The motor housing 100 includes a housing cover 110 that forms a front surface of the motor housing 100.

In addition, a plurality of air suction parts 111 are formed in the housing cover 110 to allow the air discharged from the filter assembly 40 to be sucked.

Here, the air suction unit 111, the first suction unit 112 is formed in a substantially central portion of the housing cover 110, the relatively large hole is formed through the periphery of the first suction unit 112 A second suction part 113 formed with a plurality of holes and formed with a relatively small hole is included.

The first suction part 112 and the second suction part 113 penetrate substantially circularly. In addition, the second suction part 113 may be formed on the outside of the first suction part 112, and may be formed at equal intervals over the entire surface of the housing cover 110.

The first suction part 112 and the second suction part 113 are evenly formed over the entire surface of the housing cover 110. Therefore, air may be sucked evenly over the front surface of the housing cover 110.

The first suction part 112 and the second suction part 113 may be formed at positions corresponding to the mounting part 18 of the front surface of the housing cover 110.

That is, the air intake 111 may be formed at a position corresponding to one surface of the filter member 40 provided in the filter assembly 40, in particular, the filter assembly 40.

And, as shown in Figure 5, the air intake 111 may be evenly distributed on the rear side of the mounting portion (18).

Therefore, when the suction force is applied through the air suction unit 111, the suction force may be evenly distributed to the filter assembly 40 mounted on the mounting unit 18. That is, the suction force is not concentrated only on any part of the filter assembly 40.

Since the first suction part 112 is formed to be larger than the second suction part 113, the suction force of the suction motor 130 may be greater on the side of the first suction part 112.

However, the suction force is not concentrated at any one position by the presence of the second suction part 113, and may be evenly applied over the entire surface of the housing cover 110.

Here, the through hole 46 and the air intake 111 may be formed at positions corresponding to each other. Therefore, the air discharged from the through hole 46 may be easily sucked into the air suction unit 111.

By the above configuration, dust may be evenly filtered on the front surface of the filter assembly 40. In this case, there is an advantage that dust does not accumulate and accumulate in the filter assembly 40.

As a result, since the air passage in the filter assembly 40 is smooth, the suction performance of the suction motor 130 is improved.

In the motor housing 100, a plurality of air discharge parts 102 are formed to discharge air passing through the suction motor 130 to the outside of the motor housing 100.

The air outlet 102 corresponds to the side of the suction motor 130 so that the air sucked from the front of the suction motor 130 and discharged to the side can be easily moved to the air outlet 102. It can be formed at the position.

In addition, the air passing through the filter member is discharged from the filter assembly 40 through the through hole 46.

The air discharged from the filter assembly 40 may be sucked into the motor housing 100 through the first suction part 112 and the second suction part 113. Therefore, the air may be sucked evenly to the front of the housing cover 110.

On the contrary, since air is evenly filtered across the front of the filter assembly 40, dust may be accumulated and accumulated over the front of the filter element.

Meanwhile, the air sucked into the motor housing 100 may be sucked into the front surface of the suction motor 130, and the sucked air may be discharged to the side of the suction motor 130.

In addition, the air discharged from the suction motor 130 is discharged to the outside of the motor housing 100 through the air discharge unit 102 and then folded backward, and the outside of the cleaner through the exhaust unit 150. To be discharged.

According to the air flow as described above, since the suction pressure acts evenly on the rear of the filter assembly and the front of the motor housing, there is an advantage that the air can be filtered while passing through the front of the filter member.

In this case, dust in the air may be accumulated evenly on the front surface of the filter member.

Therefore, there is an effect that the problem of deterioration of dust separation performance and suction performance can be solved by accumulating dust on only one portion of the filter member. In addition, there is an advantage that the life of the filter member can be long.
