The upper portion of the filter unit is provided with a dust removing portion 220b for removing dust accumulated on the zigzag filter from the filter, and a convex portion 220a for manually rotating the dust removing portion 220b. The upper lid unit 220 is configured to remove dust accumulated on the spiral filter by manually rotating the dust removing portion 220b by the convex portion 220a. Then, the dust removed by the dust removing unit 220b falls and accumulates on the inner cylinder portion 211. The dust accumulated on the inner cylinder portion 211 can be discarded by removing the dust partition portion 212.

Further, the dust collector 200 is arranged on the vacuum cleaner main body 100 in an inclined posture with respect to the vertical direction in order to reduce the volume of the electric vacuum cleaner 1 while maintaining the cyclone separation performance by the centrifugal separation unit described later. There is. In addition, a futon is assumed as the main object to be cleaned of the vacuum cleaner 1. As for the dust sucked from the futon, there are many fine powders as compared with the dust sucked from the flooring, the carpet and the like. Therefore, the dust sucked from the futon is deposited by the dust collector 200 at an angle inclined with respect to the axis of the dust collecting cup 210. Therefore, as shown in FIG. 11, a “dust full” line indicating a dust pool to the user is displayed on the outer surface of the dust collecting cup 210. The "full amount of dust" line is preferably displayed at an angle inclined with respect to the axis P of the dust collecting cup 210.

(Operation of vacuum cleaner 1)
The operation of the vacuum cleaner 1 according to the present embodiment will be described below. First, when cleaning an object to be cleaned such as a futon using the vacuum cleaner 1, the user holds the operation handle 300 and supports the vacuum cleaner body 100 by hand. Then, the bottom surface of the vacuum cleaner main body 100 is grounded to the object to be cleaned, and the opening 21a of the suction unit 20 and the external discharge port 3 are brought close to the object to be cleaned. When the vacuum cleaner 1 is operated, the main body circuit board 8 (control device) provided in the vacuum cleaner main body 100 operates the electric blower 61 and the rotary brush drive motor 14 of the rotary brush 4.

When the rotary brush drive motor 14 is driven, the rotary brush 4 rotates. Then, the rotation of the rotating brush 4 scrapes out pests such as dust or mites existing on the surface of the object to be cleaned such as a futon.

Here, as shown in FIG. 12, the rotary brush drive motor 14 is located in front of the rotary brush 4 and at a distance from the electric blower 61 located behind the rotary brush 4. As a result, the heat generated from the electric blower 61 is less likely to be transmitted to the rotary brush drive motor 14, and the rotary brush drive motor 14 can be operated more safely.

Further, when the electric blower 61 is operated, dust-containing air is taken in from the opening 21a. The dust-containing air taken in from the opening 21a flows into the dust collector 200 from the inflow port 210a via the nozzle pipe 5 via the separation flow path Y indicated by the arrow in FIG. 5, and enters the upper lid unit 220. It passes through and is discharged from the dust collector 200. The air discharged from the dust collector 200 is sucked into the electric blower unit 60 in which the electric blower 61 is housed.

In the dust collector 200, the upper part acts as the centrifuge part 240 with the flange part 212a on the upper part of the dust partition part 212 in the dust collecting cup 210 as a boundary. That is, in the dust collector 200, the centrifugal separation unit 240 is a swirling air passage formed by the inner side surface of the dust collection cup 210, the outer peripheral surface of the inner cylinder portion 211, and the like. The inflow port 210a opens in the tangential direction of the swirling air passage formed by the centrifuge 40. Therefore, the dust-containing air that has flowed in through the inflow port 210a swirls the swirling air passage formed by the centrifugal separation unit 240 as shown in the separation flow path Y in FIG. 4, and thus dust in the dust-containing air. Is centrifuged. Of the centrifugally separated dust, relatively large coarse dust (first dust) falls along the inner surface of the dust collecting cup 210 due to the action of centrifugal force, and is accumulated below the dust partition 212. To.

The air from which the coarse dust has been separated passes through the inner cylinder portion 211 (see the separation flow path Y in FIG. 5). At this time, the relatively small fine dust (second dust) not separated by the centrifuge portion 240 rises together with the air flow through the slit 211b of the inner cylinder portion 211. On the other hand, the coarse dust is filtered by a mesh-like filter wound around the body portion 211c. The air that has passed through the inner cylinder portion 211 passes through the filter unit housed in the upper lid unit 220 to remove fine dust (second dust) and is discharged from the dust collector 200. The dust collector 200 is a dust collector of a type that collects dust by a swirling air passage (cyclone). However, the dust collector 200 is not limited to the cyclone type dust collector, and may be a paper pack type or cloth bag type dust collector.

The air discharged from the dust collector 200 is sucked into the electric blower unit 60. The air discharged from the dust collector 200 passes through the ventilation passage 61c of the electric blower 61 that is generating heat in the electric blower unit 60, and passes through the exhaust port 61b formed on the side surface of the exhaust duct member 68. A flow path is provided that bypasses the side wall of the electric blower accommodating portion 68a. Then, it passes through the exhaust filter 7 and is discharged from the electric blower unit 60 (see the flow path Z1 in FIG. 5). At this time, the air passes through the ventilation passage 61c of the electric blower 61 that is generating heat. As a result, the air is heated to become warm air and is discharged from the electric blower unit 60. Then, the warm air discharged from the electric blower unit 60 passes through the exhaust filter 7 and is discharged to the outside from the external discharge port 3 formed on the bottom surface of the vacuum cleaner main body 100.

Here, the circuit board accommodating portion 68b of the electric blower unit 60 communicates with the electric blower accommodating portion 68a via the upstream side vent 68d and the downstream vent 68e. Therefore, a part of the air discharged from the exhaust port 61b of the electric blower 61 flows into the circuit board accommodating portion 68b through the upstream vent 68d, and is along the flow path Z2 defined by the guide rib 68f. , Passes through the circuit board accommodating portion 68b, and flows out to the electric blower accommodating portion 68a through the downstream vent 68e. Then, the air flowing out to the electric blower accommodating portion 68a through the downstream ventilation port 68e passes through the exhaust filter 7 and is discharged to the outside from the external discharge port 3 formed on the bottom surface of the vacuum cleaner main body 100.

As described above, in the vacuum cleaner 1, the hot air flow path Z1 heated by the electric blower 61 branches into the flow path Z2 in which a part of the warm air passes through the inside of the circuit board accommodating portion 68b on the way. .. The flow path Z2 passing through the inside of the circuit board accommodating portion 68b is used for cooling the main body circuit board 8 accommodated in the circuit board accommodating portion 68b. While the vacuum cleaner 1 is in operation, the temperature of the main body circuit board 8 becomes about 100 ° C. or higher. On the other hand, the temperature of the warm air heated by the electric blower 61 is about 60 ° C. to 70 ° C. Therefore, the main body circuit board 8 is cooled by being hit by the warm air heated by the electric blower 61.

Further, the flow path Z2 passing through the inside of the circuit board accommodating portion 68b rejoins the flow path Z1 on the upstream side of the exhaust filter 7. Then, the flow path Z1 and the flow path Z2 pass through a single exhaust filter 7. The air in the flow paths Z1 and Z2 is cleaned by the exhaust filter 7 and discharged to the outside from the external discharge port 3.

In the vacuum cleaner 1 that applies warm air to the object to be cleaned by using the exhaust heat of the electric blower 61, an exhaust filter 7 is mounted in order to purify the air discharged to the outside. Further, since the vacuum cleaner 1 is equipped with a control device such as a main body circuit board 8, warm air heated by the electric blower 61 is sent to the circuit board accommodating portion 68b to cool the main body circuit board 8. It needs to flow in.

Here, as a flow path configuration for cooling the main circuit board 8, all the warm air heated by the electric blower 61 is made to flow into the circuit board accommodating portion 68b, and the air discharged from the circuit board accommodating portion 68b is exhausted. A flow path configuration for passing through the filter 7 can be considered. However, in this flow path configuration, the amount and temperature of the air discharged from the external discharge port 3 may decrease due to reasons such as the warm air heated by the electric blower 61 staying in the circuit board accommodating portion 68b. There is. As a result, it is not possible to obtain a sufficient thermal effect by the air discharged from the external discharge port 3.

On the other hand, in the vacuum cleaner 1 according to the present embodiment, a part of the air passing through the ventilation passage 61c of the electric blower 61 flows into the circuit board accommodating portion 68b through the upstream ventilation port 68d. The flow path configuration is such that the rest does not flow into the circuit board accommodating portion 68b. Therefore, the amount of air discharged from the external discharge port 3 can be maintained. Therefore, a sufficient heat effect can be obtained by the air discharged from the external discharge port 3, and the main circuit board 8 can be sufficiently cooled.

When cleaning an object to be cleaned such as a futon using the vacuum cleaner 1, the user grounds the bottom surface of the vacuum cleaner body 100 to the object to be cleaned such as a futon, and makes the opening 21a and the external discharge port 3 the object to be cleaned. The vacuum cleaner main body 100 is moved in the direction of the arrow X shown in FIG.

When the user cleans, first, warm air is blown to the object to be cleaned through the external discharge port 3. By blowing the exhaust warm air of the electric blower 61 onto the cleaning object such as a futon in this way, the cleaning object is heated. As a result, tentacles such as mites clinging to the futon cotton are separated from the futon cotton, and pests are weakened. The pests weakened in this way are sucked into the vacuum cleaner main body 100 through the opening 21a.

In this way, in the vacuum cleaner 1, when it passes through the electric blower 61, it is heated by the exhaust heat (to be exact, the exhaust heat of the drive motor), becomes warm air, and is discharged from the external discharge port 3 ( exhaust). In this way, by utilizing the exhaust heat of the electric blower 61, the exhaust gas can be heated without separately providing a heater, and the configuration of the vacuum cleaner 1 can be simplified and the power consumption can be suppressed. it can.

Here, in the vacuum cleaner 1 according to the present embodiment, the rotary brush 4 is housed inside the suction unit 20 having the opening 21a (suction port). Then, in the suction unit 20, the rotary brush 4 is provided so as to be exposed from the opening 21a. In other words, the rotary brush 4 is provided between the opening 21a and the external discharge port 3, and is arranged in the vicinity of the opening 21a.

As a result, in the vacuum cleaner 1, the operation of scraping out pests such as dust or mites from the surface of the object to be cleaned such as the futon by the rotating brush 4 and the suction operation are performed in the vicinity of the opening 21a of the suction unit 20. Therefore, the pests weakened by the warm air can be efficiently sucked into the vacuum cleaner main body 100.

The moving direction of the vacuum cleaner main body 100 is not limited to the direction of the arrow X, but can be the direction opposite to the arrow X. It is also possible to reciprocate the vacuum cleaner body 100 for cleaning. In this case, when the vacuum cleaner main body 100 is moved in the direction opposite to the arrow X direction, the effect is that the moisture of the object to be cleaned such as the futon can be removed by the warm air from the external discharge port 3. Further, it has an effect that dust and the like can be collected by suction from the opening 21a due to the rotation of the rotating brush 4. Further, by blowing the exhaust of warm air heated by the electric blower 61, the moisture contained in the cleaning object such as the futon is removed, and the cleaning object such as the futon can be fluffed. .. It should be noted that such an effect is achieved regardless of the moving direction of the vacuum cleaner main body 100.

Further, in the vacuum cleaner 1, a partition wall 21c for partitioning between the opening 21a as a suction port and the external discharge port 3 is provided on the bottom surface of the lower base 122 of the vacuum cleaner main body 100. The partition wall 21c can prevent the warm air discharged from the external discharge port 3 from being sucked into the opening 21a. Therefore, it is possible to prevent excessive circulation of exhaust air between the opening 21a (suction port) and the external exhaust port 3 in the vacuum cleaner main body 100, and an excessive temperature rise of the vacuum cleaner main body 100 due to exhaust circulation. Can be prevented. As a result, the safety and reliability of the vacuum cleaner 1 can be improved.

Further, since the roller 16 is housed in the roller accommodating portion 21d of the suction unit 20, the vacuum cleaner 1 can be easily moved and the operability is improved.

Although the partition wall 21c is provided on the bottom surface of the lower base 122, it may be provided on the brush housing 21 side of the suction unit 20. In this case, the partition wall 21c is integrally formed with the brush housing 21. More specifically, a part of the side wall constituting the roller accommodating portion 21d is composed of the partition wall 21c described above.

Since the roller 16 is housed in the roller accommodating portion 21d having the partition wall 21c as a part of the side wall in this way, the vacuum cleaner 1 can be easily moved and the operability is improved.

13A and 13B show a modified example of the vacuum cleaner 1 shown in FIG. 1, FIG. 13A is a side view, FIG. 13B is a bottom view, and FIG. 13C is a bottom view. Is a front view seen from the front side. As shown in FIGS. 13 (a) to 13 (c), the vacuum cleaner 1a is provided with ribs 21e for preventing forward tilting from the brush housing 21 in the forward direction. The front fall prevention rib 21e is a structure of a plate body or a box body, and extends in a direction substantially parallel to the surface of the object to be cleaned.

As a result, when the user lifts the vacuum cleaner main body 100 through the operation handle 300 and pushes it from the rear, it is possible to prevent the vacuum cleaner main body 100 from leaning forward. Therefore, it is possible to prevent an excessive force from being required when moving the vacuum cleaner main body 100.

[Embodiment 2]
Other embodiments of the present invention will be described below with reference to FIGS. 14 and 15. For convenience of explanation, the members having the same functions as the members described in the above-described embodiment are designated by the same reference numerals, and the description thereof will be omitted.

In the vacuum cleaner according to the present embodiment, the configuration of the rotary brush 4 is different from that of the first embodiment. 14A and 14B show the configuration of the rotary brush 4 of the vacuum cleaner according to the present embodiment, FIG. 14A is a side view, and FIG. 14B is a perspective view. Further, FIG. 15A is a cross-sectional view showing an example of the configuration of the rotary brush 4 of the vacuum cleaner according to the present embodiment, and FIG. 15B has a configuration different from that of FIG. 15A. It is sectional drawing which shows the rotary brush 4 which has, and FIG. 15 (c) is the sectional view which shows the rotary brush 4 which has a structure different from (a) and (b) of FIG. FIG. 16 is a side view showing the configuration of the tapping member 4b1 shown in FIG. 15 (b) when it is removed from the brush base 4d.

As shown in FIGS. 14A and 14B, the rotary brush 4 includes a rotary shaft portion 4a, a tapping member 4b, and a brush member 4c. The tapping member 4b and the brush member 4c are provided so as to cover the rotating shaft portion 4a, and extend spirally in the rotation direction of the rotating shaft portion 4a. As shown in FIGS. 15A and 15C, the rotating shaft portion 4a is provided with a brush base portion 4d that serves as an installation portion for the tapping member 4b and the brush member 4c. A plurality of protrusions 4e are formed on the brush base 4d so as to extend in the direction of the rotation shaft portion 4a. The brush member 4c is inserted between two adjacent protrusions 4e.

Further, the tapping member 4b includes an insertion portion 4f inserted between two adjacent protrusions 4e and a tapping portion main body 4g connected to the insertion portion 4f. The tapping portion main body 4g protrudes from the protrusion 4e of the brush base 4d. The tapping member 4b is made of a material that is more flexible than the brush member 4c, for example, a rubber material.

Along with the rotational drive of the rotary brush 4, the brush base 4d rotates about the rotary shaft 4a. Along with this rotation, the brush member 4c inserted between the protrusions 4e repeatedly abuts on the object to be cleaned, so that the dust existing on the surface of the object to be cleaned is scraped up.

Further, the tapping member 4b rotates around the rotation shaft portion 4a together with the brush base portion 4d as the rotating brush 4 rotates. The tapping member 4b is made of a material that is more flexible than the brush member 4c. Therefore, in the tapping members 4b1 and 4b3, the striking portion main body 4g1 and 4g3 bends in the direction perpendicular to the rotating shaft portion 4a due to the centrifugal force caused by the rotation of the rotating shaft portion 4a. As a result, in the state where the rotating shaft portion 4a is rotating, the striking portion main bodies 4g1 and 4g3 of the striking members 4b1 and 4b3 extend in a direction perpendicular to the rotating shaft portion 4a with respect to the brush member 4c due to centrifugal force. Therefore, the tapping members 4b1 and 4b3 are more likely to come into contact with the surface of the object to be cleaned than the brush member 4c. Therefore, in the rotating brush 4, the tapping members 4b1 and 4b3 strike the cleaning object immediately after the dust existing on the surface of the cleaning object is scraped up by the brush member 4c.

Further, as shown in FIG. 16, the tapping member 4b2 may be provided with a notch 4h on the side in contact with the object to be cleaned. When the tapping portion main body 4g2 bends in the direction perpendicular to the rotating shaft portion 4a due to the centrifugal force generated by the rotation of the rotating shaft portion 4a, the tapping portion main body 4g2 is shortened between the notch portions 4h. Therefore, the flexibility of the tapping portion main body 4g2 can flexibly respond to the rotation of the rotating shaft portion 4a. As a result, the tapping effect can be sufficiently exerted.

Further, the cutout portion 4h is arranged so as to be at the same position (position of the alternate long and short dash line L2 in FIG. 16) as the arrangement of the rib 21b described above (the alternate long and short dash line L1 in FIGS. 4 and 20). That is, the cutout portion 4h is provided at a position (one-point broken line L2) intersecting the one-point broken line L1 which is a virtual line extending along the rib 21b in the rotating brush 4. As a result, the rib 21b and the notch portion 4h of the tapping portion main body 4g2 are located substantially in a straight line. Therefore, when the rotary brush 4 rotates, the notch 4h creates a gap between the tapping portion main body 4g2 and the rib 21b, and the tip portion of the tapping portion main body 4g2 comes into contact with the tip portion of the rib 21b. Can be prevented. Further, by providing a gap between the tapping portion main body 4g2 and the rib 21b, it is possible to prevent a part of the object to be cleaned such as a futon from being caught in the rotating brush 4. Further, since air flows in from the space between the ribs 21b through the gap, the portion of the cleaning object facing the rib 21b and the vacuum cleaner main body 100 are easily separated from each other, and the cleaning object can be effectively hit. Can be done. The cutout portion 4h is not limited to the tapping member 4b2, and may be provided in, for example, the tapping members 4b1 and 4b3. Preferably, the notch portion 4h is provided in a striking member whose main body is not annular, for example, a striking member 4b2 / 4b3.

As the rotating brush 4 rotates, the tapping member 4b strikes the object to be cleaned, so that the pests weakened by the warm air exhausted from the electric blower 61 are released from the object to be cleaned. Therefore, the weakened pests can be efficiently sucked into the vacuum cleaner body.

Further, in the vacuum cleaner according to the present embodiment, since the rotary brush 4 is provided with the tapping member 4b and the brush member 4c, the rotary driving force of the drive motor is used to scrape out dust and tap the object to be cleaned. It is doing both operations. Therefore, it is not necessary to separately provide a tapping mechanism for the object to be cleaned, and the weight and size of the vacuum cleaner main body can be reduced.

The shape of the tapping portion main body of the tapping member may be any shape that is flexible in the direction perpendicular to the rotating shaft portion 4a due to the centrifugal force generated by the rotation of the rotating shaft portion 4a. For example, as shown in FIG. 15A, the striking portion main body 4g1 may have a ring-shaped cross section perpendicular to the rotating shaft portion 4a. Further, as shown in FIG. 15B, the tapping portion main body 4g2 may have a cross-sectional shape perpendicular to the rotation shaft portion 4a having a constricted portion. Further, the shape is not limited to the shapes of the tapping portion main body 4g1 and 4g2 shown in FIGS. 15A and 15B, and as shown in FIG. 5C, the tapping portion main body 4g3 is in the rotation direction. The blade shape may be inclined to.

In the configurations (a) to (c) of FIG. 15, two tapping members 4b1 and 4b2.4b3 and two brush members 4c were provided with respect to the brush base 4d, and were alternately arranged in the rotation direction. .. However, the configurations such as the number and arrangement of the tapping members 4b1 and 4b2.4b3 and the brush members 4c are not limited to the configurations of FIGS. 15A to 15C, and the configuration of the vacuum cleaner main body 100 and the main objects to be cleaned It can be appropriately designed according to the type and the like.
