Figure 4 is an exploded perspective view showing a flow path switching device according to an embodiment of the present invention, Figures 5a and 5b is a view showing a flow path switching structure according to an embodiment of the present invention around the valve assembly, Figure 6a and Figure 6b is a perspective view showing the operation of the flow path switching device according to an embodiment of the present invention, with reference to this will be described the flow path switching device of the present embodiment.

The flow path switching device 100 of the present embodiment includes a valve assembly 110 and a driving unit 120 for driving the valve assembly 110.

The valve assembly 110 is coupled to the first valve 111 to open and close the first flow passage 41, the second valve 112 to open and close the second flow passage 42, and the first valve 111 to one side. And a rotating shaft 113 coupled to the second valve 112 on the other side and disposed at an intersection of the first flow passage 41 and the second flow passage 42.

As shown in FIGS. 5A and 5B, the first valve 111 and the second valve 112 of the present embodiment form a V-shape with each other and are coupled to the rotation shaft 113, and at this time, the first valve 111. ) And the tip of the second valve 112 extends downstream of the first passage 41 and downstream of the second passage 42, respectively.

Accordingly, as shown in FIG. 5A, the first passage 41 is opened by the first valve 111 and the second passage 42 is closed by the second valve 112. As shown, the first passage 41 is closed by the first valve 111 and the second passage 42 is opened by the second valve 112.

In addition, the first valve 111 and the second valve 112 of the present embodiment are rotated in the same direction as the flow direction of the intake air, respectively, so as to close the first flow passage 41 and the second flow passage 42. The leakage of suction force through the flow path is reduced.

For example, as shown in FIG. 5A, when opening the first flow passage 41 and closing the second flow passage 42, the second valve 112 is downstream from the upstream side of the flow (ie, A). Direction) to close the second flow path 42, so that the second valve 112 more strongly closes the second flow path 42 by the suction force transmitted from the suction fan.

On the contrary, as shown in FIG. 5B, when the first passage 41 is closed and the second passage 42 is opened, the first valve 111 is downstream from the upstream side of the flow (ie, in the B direction). ) And closes the first flow path 42. Reference numeral g denotes a flow direction of the intake air.

The vacuum cleaner of the present embodiment further includes flange portions 114 and 115 provided in the first passage 41 and the second passage 42 so that the passage is more tightly closed by the valves 111 and 112. Specifically, when the first flow passage 41 is closed, the first flange portion 114 of the first flow passage 41 is interviewed with the edge of the first valve 111, and when the second flow passage 42 is closed. The second flange portion 115 provided in the second flow passage 42 is in contact with the edge of the second valve 112.

In addition, the cleaner may further include a sealing member provided in the flange portion (114, 115) or the valve (111, 112) in close contact with the flange portion (114, 115). The sealing member 116 of the present embodiment is provided in the first valve 111 and the second valve 112, the center is provided with a convex portion 117 to match the cross section of the flow path further improves the sealing force.

The driving unit 120 is elastically supported by the main body so that the actuator 121 linearly moves by the rotation of the main body 20 and the rotation shaft 113 of the valve assembly 110 rotates by the linear motion of the actuator 121. One end has a link 122 that is pivotally coupled to the actuator 121 and the other end is fixedly coupled to the pivot shaft 113. Reference numeral 123 denotes an elastic body elastically supporting the actuator 121 against the brush assembly 10.

Accordingly, the main body 20, the actuator 121, and the rotation shaft 113 are interlocked with each other so that the rotation shaft 113 of the valve assembly 110 is rotated by the rotation of the main body 20. The 41 or the second passage 42 is selectively opened and closed.

Specifically, as shown in FIG. 6A, when the main body 20 is inclined at a predetermined angle with respect to the brush assembly 10, the lower end 124 of the actuator 121 is spaced apart from the brush assembly 10, and thus, the actuator 121. ) Maintains a state of being elastically supported downward, and accordingly, the brush assembly 10 linked with the actuator 121 also rotates in a direction so that the first flow path 41 is opened and the second flow path 42 is maintained. ) Is closed. At this time, since the main body 20 is rotated in a predetermined angle range and the brush assembly 10 is generally used, even if the main body 20 is rotated in a predetermined range in a tilted state, the lower end portion 124 of the actuator 121 is a brush assembly. It is preferable to design so as not to contact (10). In this embodiment, the predetermined range is the first rotation range α.

In addition, as shown in FIG. 6B, when the main body 20 is erected with respect to the brush assembly 10, the actuator 121 is pressed by the brush assembly 10 to move upwards, and interlocks with the actuator 121. The brush assembly 10 is rotated in the b direction, so that the first flow passage 41 is closed and the second flow passage 42 is opened.

In the following, the cleaning operation using the cleaner of the present embodiment will be briefly described.

When cleaning the bottom surface of the carpet, the floor, etc., the user pushes and pulls the handle 32 back and forth while tilting the main body 20 so that foreign matter is effectively sucked through the brush assembly 10 and performs cleaning. . At this time, even if the main body 20 is rotated back and forth within the first rotation range (α), the lower end portion 124 of the actuator 121 does not contact the brush assembly 10, the open state of the first flow path 41 And the second channel 42 is closed, and the suction force of the suction fan is concentrated in the first channel 41.

When cleaning the gaps, curtains, ceilings, etc. using the auxiliary suction device 30, the user separates the wand assembly 31 from the main body 20 while the main body 20 is upright with respect to the brush assembly 10. Perform the cleaning. At this time, as the main body 20 is rotated, the actuator 121 is pressed by the brush assembly 10, the valve assembly 110 is interlocked with the actuator 121 is rotated to close the first passage 41 By opening the second passage 42, the suction force of the suction fan is concentrated in the second passage 42.

As described above, in the cleaner according to the present embodiment, in order to use the brush assembly 10 or the auxiliary suction device 30, the user does not need to separately operate the flow path switching device 100. In other words, when the user performs the cleaning using the brush assembly 10 while tilting the main body 20 by a predetermined angle, the first passage 41 connected to the brush assembly 10 is automatically opened and the auxiliary suction device. The second flow passage 42 connected to 30 is automatically closed. In addition, when the user sets the main body 20 in the brush assembly 10 to use the auxiliary suction device 30, the second passage 42 connected to the auxiliary suction device 30 is automatically opened and the brush assembly ( The first flow passage 41 connected to 10 is closed.

Therefore, the trouble of switching the flow path in accordance with the cleaning mode is eliminated, and the ease of use is increased.

In addition, in the vacuum cleaner of the present invention, since the structure of the flow path switching device 100 for automatically switching the flow path is relatively simple, the productivity of the vacuum cleaner is improved.

In the above, the upright cleaner has been described as an example, but the cleaner of the present invention can be applied to all the cleaners having two suction paths, and the present invention can be variously modified.

For example, the valve assembly 110 described herein has one pivot shaft 113, but each valve can have separate pivot shafts.

In addition, the driving unit may include a separate driving motor, wherein the driving motor may be controlled based on a signal generated from a sensor for detecting a posture of the main body.
