The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
First, the motor front wind guide structure 100 of the cleaner 1000 according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings. The motor front air guiding structure 100 is applied to the dust collector 1000, the dust collector 1000 may include a dust cup 300 and a motor 200, the motor front air guiding structure 100 may be connected between an upper cover of the dust cup and the motor 200, so as to guide air to flow from the dust cup 300 to the motor 200, specifically, the dust cup 300 is located on one side of the motor front air guiding structure 100 and the motor 200, and the motor front air guiding structure 100 may be located above the motor 200.
As shown in fig. 1 to 4, a front wind guide structure 100 of a motor according to an embodiment of the present invention includes a lower cover 20 and an upper cover 10.
The lower housing 20 is connected to a suction port 201 of a motor 200 of the vacuum cleaner 1000, the lower housing 20 can be connected to a housing of the motor 200, or directly integrated with the housing of the motor 200, the upper housing 10 is connected to the lower housing 20, for example, the upper housing 10 can be fastened to the lower housing 20.
The upper housing 10 and the lower housing 20 together define a motor front air guide chamber 102, the upper housing 10 has a main air inlet 11, the main air inlet 11 is adapted to communicate with a dust cup 300 of the vacuum cleaner 1000, and specifically, the main air inlet 11 is adapted to communicate with an outlet of an upper cover of the dust cup.
The upper mask body 10 further has an upper guide portion 14, the upper guide portion 14 is disposed opposite to the suction port 201 of the motor 200, the upper guide portion 14 extends toward the suction port 201 of the motor 200, and the upper guide portion 14 may protrude inward into the motor front air guide chamber 102.
The airflow is sucked into the motor front air guiding cavity 102 from the main air inlet 11, the airflow rotates and flows downwards in the motor front air guiding cavity 102 along the outer wall of the upper cover body 10 and the upper guide part 14, and enters the motor 200 through the suction port 201 of the motor 200, and the upper guide part 14 can play a role of guiding the airflow so that the airflow forms a vortex before entering the motor 200. The upper guide part 14 just fills up the space of the vortex, so that the air guide efficiency is improved, and the upper guide part 14 can be arranged opposite to the suction port 201 of the motor 200.
That is, the tapered wind scooper is added before the motor 200 enters the air, so that the airflow becomes orderly, the disordered airflow scouring is slowed down, the pneumatic noise is reduced, the resistance loss is reduced, the efficiency is improved, the working sound of the dust collector 1000 is maintained below the comfortable sensory range of the ears, and the noisy and fidgety use experience is eliminated.
According to the motor front air guide structure 100 provided by the embodiment of the invention, the air flow can be effectively guided to enter the motor 200, so that the air flow is ordered, the aerodynamic noise is reduced, the resistance loss is reduced, and the silencing effect and the air suction efficiency of the dust collector 1000 are improved.
In some preferred embodiments of the present invention, as shown in fig. 2 and 4, the upper guide portion 14 may be gradually narrowed toward the suction port 201 of the motor 200. In this way, the upper guide portion 14 has a stronger guiding effect on the formation of the vortex of the air flow, for example, the upper guide portion 14 may have a tapered shape, a truncated cone shape, or the like.
Preferably, the upper guide 14 may be coaxial with the motor 200. Thus, the airflow vortex guided by the upper guide portion 14 can directly enter the motor 200, and the resistance loss can be reduced.
As shown in fig. 3 and 4, a guide grid 12 may be disposed at the air inlet 11 of the main frame, and the guide grid 12 is used for guiding the airflow from the dust cup 300 to the front wind cavity 102 of the motor, reducing the turbulence of the airflow, and assisting the formation of the vortex.
As shown in fig. 3, the guide grill 12 may be disposed at one side of the upper housing 10 and adjacent to one sidewall of the upper housing 10. That is, the guide grate 12 is not centrally located, thereby facilitating the formation of a vortex in the airflow.
Further, the orientation of the guide grill 12 is offset to one side of the upper guide portion 14. It can be understood that the air current can flow in from one side of the upper guide 14 by the guiding of the guide grill 12, forming a vortex around the upper guide 14, and the air guiding efficiency is higher.
As shown in fig. 2 and 4, a lower guide 22 is provided at a connection portion of the lower housing 20 and the suction port 201 of the motor 200, the lower guide 22 is disposed opposite to the upper guide 14, and the lower guide 22 is configured in a shape gradually decreasing toward the suction port 201 of the motor 200, for example, the lower guide 22 may be tapered. The lower guide portion 22 may receive airflow vortexes from top to bottom into the motor 200 corresponding to the airflow vortexes above.
The invention also discloses a dust collector 1000.
As shown in fig. 1 to 4, a vacuum cleaner 1000 according to an embodiment of the present invention is provided with a motor front air guiding structure 100 according to any of the embodiments described above.
The dust collector 1000 according to the embodiment of the invention has high working efficiency and good silencing effect.
