It has the timing belt 23 passed.

  Further, on both left and right end portions of the front upper case 14, as shown in FIGS. 1, 2, and 7, the front end portion is inclined obliquely upward and the front end portion projects forward from the front edge of the front upper case 14. Support plates (support members) 24 and 24 are integrally provided. A cleaning body support member 25 is disposed on the front side of the front upper case 14.

  The cleaning body support member 25 rotatably supports the wall-side rotary cleaning body 29 and protrudes to the front side of the suction port body 10a so as to be movable forward and backward with respect to the main rotary cleaning body 18 and the cleaning surface S. Link mechanism. Specifically, the cleaning body support member 25 is provided integrally with the front plate portion 25a extending in the left-right direction and both ends of the front plate portion 25a, and outside the support plates 24, 24 (opposite surfaces of the support plates 24, 24). Side plate portions 25b and 25b disposed on the side opposite to the side). The side plate portions 25b, 25b extend vertically, and the upper end portions of the side plate portions 25b, 25b are attached to the support plates 24, 24 so as to be rotatable about a rotation shaft 26 extending in the left-right direction.

  Further, as shown in FIGS. 4 to 6, a flange-like spring receiver 27 is formed on the opposing surface 24a of the support plates 24, 24, and the gap between the spring receiver 27 and the front plate portion 25a is as shown in FIG. As shown in FIG. 5, a torsion coil spring (turning biasing means) 28 wound around the turning shaft 26 is interposed. In the normal state, the torsion coil spring 28 rotates the cleaning body support member 25 around the rotation shaft 26 so that the side plate portion 25b is inclined obliquely downward and forward as shown in FIG. The spring is biased so as to be separated from the main rotary cleaning body 18 and the cleaning surface S. The cleaning body support member 25, the rotation shaft 26, the torsion coil spring 28, and the like constitute a support structure (contact means) B.

  Further, between the lower end portions of the side plate portions 25b, 25b, a wall-side rotary cleaning body 29 extending in the left-right direction is disposed as shown in FIG.

  Further, as shown in FIG. 7, the support plate 24 is attached with a microswitch 30 that is a sensor for detecting the edge of the wall (edge detection means).

  In addition, the wall-side rotary cleaning body 29 comes into contact with the wall 31 as shown in FIG. 8A from the state where it is separated from the main rotary cleaning body 18 as shown in FIG. When it is moved rearward to a position where it comes into contact with the main rotary cleaning body 18, the side plate portion 25b is rotated rearward about the rotation shaft 26 against the spring force of the torsion coil spring 28, and the side plate portion 25b is rotated. Thus, the microswitch 30 is turned on. The ON signal (wall detection signal) from the microswitch 30 is input to the arithmetic control circuit (control means) 32 in FIG. An operation signal from the operation panel 8a is also input to the arithmetic control circuit 32. The arithmetic control circuit 32 controls the rotation of the electric blower 5 and the drive motor 21.

[Action]
Next, the operation of the vacuum cleaner having such a configuration will be described.

(1) Cleaning of normal cleaning surface S When the switch S1 for switching “weak / medium” suction air volume or the switch S2 for “strong” suction air volume provided on the hand operation pipe 8 is turned on, the arithmetic control circuit 32 is electrically operated. The blower 5 is operated, and the suction negative pressure of the electric blower 5 is applied to the dust collection chamber 3.

  The suction negative pressure acting on the dust collection chamber 3 is the suction chamber of the suction port body 10a through the paper pack filter 4, the dust collection hose 7, the hand operation pipe 8, the extension pipe 9, and the connection pipe 17 in the state shown in FIG. Acts on 15.

  On the other hand, when the wall-side rotary cleaning body 29 is not in contact with the wall 31 in FIGS. 7 and 8, the side plate portion 25b of the cleaning body support member 25 is moved into FIGS. 7 and 7A by the spring force of the torsion coil spring 28 in FIGS. As shown in FIG. 2, the wall-side rotary cleaning body 29 that is inclined obliquely downward toward the front and is held at the lower end of the side plate portion 25b floats (is separated) from the cleaning surface S, and The rotary cleaning body 29 is separated from the main rotary cleaning body 18 to the front side.

  In this state, the arithmetic control circuit 32 controls the operation of the drive motor 21 by turning on the switches S1 and S2, and rotates the drive motor 21 via the timing pulleys 21b and 18e of the power transmission means 22 and the timing belt 23. The main rotary cleaning body 18 is transmitted to the main rotary cleaning body 18 and rotated in the counterclockwise direction (rotation direction for applying a rotational force in the forward direction to the suction port body 10) as indicated by an arrow A1 in FIG.

  Thereby, the main rotary cleaning body 18 projects a part of the brush bristle band 18b downward from the suction opening 15a while rotating, and causes the brush bristle band 18b to scrape dust on the cleaning surface S backward.

  The suction negative pressure acting on the suction chamber 15 sucks a part of the dust on the cleaning surface S directly into the suction chamber 15 together with air (air), while the cleaning surface S scraped up by the main rotary cleaning body 18. Dust is sucked into the suction chamber 15 together with air (air).

  Further, the air containing dust sucked into the suction chamber 15 is sucked into the paper pack filter 4 via the connecting pipe 17 extension pipe 9, the hand operation pipe 8 and the dust collecting hose 7, To Penetrate.

  At this time, the dust sucked together with the air is captured by the paper pack filter 4 and the air passing through the paper pack filter 4 is cleaned. The purified air is sucked into the electric blower 5 to cool the inside, and finally exhausted to the outside.

  Therefore, by moving the suction port body 10a of the suction port body 10 along the cleaning surface S, cleaning in a normal state can be performed.

(2) Cleaning at the wall When the suction port body 10 is moved to the wall 31 side in accordance with such cleaning work, the wall-side rotary cleaning body 29 first hits the wall 31 as shown in FIG. When the suction port body 10 is further moved to the wall 31 side from this state, the wall-side rotary cleaning body 29 and the side plate portion 25b are centered on the rotating shaft 26 against the spring force of the torsion coil spring 28 of FIGS. And can be rotated together in the rear.

  Then, along with this rotation, the wall-side rotary cleaning body 29 is brought into contact with the main rotary cleaning body 18 as shown in FIGS. 8B and 8A, and is indicated by an arrow A2 by the rotational force of the main rotary cleaning body 18. As described above, the main rotary cleaning body 18 is rotated in the opposite direction (clockwise direction), and the wall-side rotary cleaning body 29 is brought into contact with the cleaning surface S so as to be near the wall 31 of the cleaning surface S (near the wall). Raise the dust.

  In FIG. 8B, the brush bristle band 29a of the wall-side rotary cleaning body 29 is illustrated in a state where it does not reach the wall-side portion that is a boundary between the cleaning surface S and the wall 31. By moving the suction inlet 10 slightly toward the wall 31, the brush bristle band 29 a can be bent and contact the entire portion of the cleaning surface S near the wall.

  Therefore, the brush bristle band 29a of the wall-side rotary cleaning body 29 can scrape up dust on the entire wall surface of the cleaning surface S. In the state shown in FIG. 8B, the dust near the wall of the cleaning surface S is scraped up to the wall 31 by the brush bristles 29a of the rotary cleaning body 29 near the wall. It is moved from the upper side of the rotary cleaning body 29 to the main rotary cleaning body 18 side. Moreover, the moved dust is picked up again by the main rotary cleaning body 18 and sucked into the suction chamber 15.

  8B, the side plate portion 25b turns on the microswitch 30 at the position where it is brought into contact with the main rotary cleaning body 18, and the ON signal (wall detection signal) of the microswitch 30 is arithmetically controlled. It is input to the circuit 32. Therefore, when the wall 31 is detected, the calculation control circuit 32 can slow down the rotation of the drive motor 21 and slow down the rotation of the rotary cleaning bodies 18 and 29.

(Modification 1)
By the way, since the path | route until the dust scooped up by the rotary cleaning body 29 near a wall is sucked into the suction chamber 15 becomes long as mentioned above, in order to shorten this path | route, the rotary cleaning body 29 near a wall is shown in FIG. It may be rotated in the opposite direction to b).

  In this case, when the microswitch 30 is turned on and the wall 31 is detected, the arithmetic control circuit 32 receives this ON signal and reverses the drive motor 21. As a result, the rotation of the main rotary cleaning body 18 is rotated in the clockwise direction as indicated by the arrow A3 in FIG. It is rotated counterclockwise as indicated by A4.

  Accordingly, the dust on the wall of the cleaning surface S is scraped up to the main rotary cleaning body 18 side by the wall-side rotary cleaning body 29, while the main rotary cleaning body 18 removes the dust on the cleaning surface S to the side of the rotary cleaning body 29. Therefore, the dust thus picked up is moved upward by the rotary cleaning bodies 18 and 29 and sucked into the suction chamber 15 through the gap between the main rotary cleaning body 18 and the front upper case 14. . In addition, since the flow to the suction chamber 15 due to the negative pressure of the suction chamber 15 is generated between the plurality of brush bristle bands 18b of the main rotary cleaning body 18, the dust that has been scraped up is drawn along the flow. Sucked into.

  As a result, the path through which the dust scraped up by the wall-side rotary cleaning body 29 is sucked into the suction chamber 15 is shortened.

(Modification 2)
Further, in addition to the configuration of the suction port body 10 described above, as shown in FIG. 10, an idle brush 33 (a brush having a sufficiently smaller diameter than the main rotary cleaning body 18) that contacts the main rotary cleaning body 18 is provided. It is good also as a structure. In this case, the idle brush 33 is provided in parallel with the main rotary cleaning body 18 and both ends thereof are rotatably held by the bearing support portions 11a and 11b of the lower case 11 in FIG.

  Also in this configuration, when the wall-side rotary cleaning body 29 is not in contact with the wall 31 as shown in FIG. 10, the wall-side rotary cleaning body 29 has a spring force (biasing force) of the torsion coil spring 28 of FIGS. 4 to 6. Thus, it is separated from the idle brush 33 to the front side and floats upward from the cleaning surface S.

  In this state, the arithmetic control circuit 32 controls the operation of the drive motor 21 by turning on the switches S1 and S2, and rotates the drive motor 21 via the timing pulleys 21b and 18e of the power transmission means 22 and the timing belt 23. The rotation cleaning body 18 is transmitted, and the main rotation cleaning body 18 is rotated in the counterclockwise direction (rotation direction for applying a rotational force in the forward direction to the suction port body 10) as indicated by an arrow A1 in FIG. Dust on the cleaning surface S is scraped up only by the rotary cleaning body 18.

  At this time, the idle brush 33 is rotated in a direction opposite to the rotation direction of the main rotary cleaning body 18 by the rotational force of the main rotary cleaning body 18.

  On the other hand, since the electric blower 5 is driven by the ON operation of the switches S1 and S2, and the suction negative pressure by the electric blower 5 acts on the suction chamber 15 of the suction port body 10, a part of the dust on the cleaning surface S and The dust scraped up by the main rotary cleaning body 18 is sucked into the suction chamber 15 together with air and is captured by the paper pack filter 4.

  Accordingly, when the suction port body 10 is moved on the cleaning surface S, the dust on the cleaning surface S is picked up by the main rotary cleaning body 18 and sucked into the suction chamber 15, as described above. Be captured.

  Then, when the suction port body 10 is moved forward to the wall 31 side, the wall-side rotary cleaning body 29 is first brought into contact with the wall 31 as shown in FIG. When the suction port body 10 is further moved to the wall 31 side from this position as shown in FIG. 11, the wall-side rotary cleaning body 29 is pressed against the wall 31, and the wall-side rotary cleaning body 29 and this Is moved to the idle brush 33 side against the spring force (biasing force) of the torsion coil spring 28, the wall-side rotary cleaning body 29 contacts the idle brush 33, and the wall-side rotary cleaning body. 29 comes into contact with the cleaning surface S.

  As a result, the rotation of the main rotary cleaning body 18 is transmitted to the wall-side rotary cleaning body 29 via the idle brush 33, so that the wall-side rotary cleaning body 29 is rotated in the same direction as the main rotary cleaning body 18. The brush bristle band 29b of the wall-side rotary cleaning body 29 scrapes up the wall dust to the main rotary cleaning body 18 side. The dust thus picked up falls on the cleaning surface S, is finally picked up by the main rotary cleaning body 18 and sucked into the suction chamber 15, and is captured by the paper pack filter 4 as described above. The

  As described above, the suction port body 10 according to the embodiment of the present invention includes the suction port body 10a having the suction chamber 15 extending in the left-right direction, and the suction opening 15a of the suction chamber 15 opening on the bottom surface, and the suction port. A main rotary cleaning body 18 is provided that is disposed along the opening 10a and that is rotatably held by the suction port body 10a. In addition, the suction port body 10 is parallel to the main rotary cleaning body 18 and in a state of protruding forward from the suction port body 10a, the wall-side rotary cleaning body 29 held rotatably by the suction port body 10a, Drive means (drive motor 21) is provided for rotating the wall-side rotary cleaning body 29 at least near the wall.

  According to such a configuration, when the suction inlet main body 10a moves to the wall, the wall-side rotary cleaning body 29 is driven to rotate, and the dust near the wall of the cleaning surface S is scraped by the wall-side rotary cleaning body 29. It can be lifted and sucked into the suction chamber 15, so that the cleaning of the wall can be performed reliably.

  In addition, the suction port body 10 of the embodiment of the present invention has a suction chamber 15 extending in the left-right direction, and a suction port body 10a in which the suction opening 15a of the suction chamber 15 opens on the bottom surface, along the suction opening 10a. And a main rotary cleaning body 18 rotatably held by the suction port main body 10a, and a drive means (drive motor 21) for driving the main rotary cleaning body 18 to rotate. In addition, the suction port body 10 includes a wall-side rotary cleaning body 29 that is rotatably supported by the suction port body 10a in a state of protruding forward from the suction port body 10a, and the wall-side rotary cleaning body. 29 is provided so as to be interlocked with the main rotary cleaning body 18.

  According to such an invention, when the suction inlet main body 10a moves to the wall side, the wall-side rotary cleaning body 29 is driven to rotate in conjunction with the main rotary cleaning body 18, so that the dust at the wall side of the cleaning surface S becomes dusty. Can be lifted up by the rotary cleaning body 29 by the wall and sucked into the suction chamber 15, so that the rotary cleaning body 29 by the wall is not provided by a drive means different from the drive means of the main rotary cleaning body 18. It can be rotated and driven to reliably clean the wall. Further, the wall-side rotary cleaning body 29 is held in parallel with the main rotary cleaning body 18.

  Further, in the suction port body 10 of the embodiment of the present invention, when the wall-side rotary cleaning body 29 moves forward to the wall side, the wall-side rotary cleaning body 29 is detected at least on the cleaning surface S by sensing the wall side. Contact means (support structure B including the cleaning body support member 25, the rotation shaft 26, the torsion coil spring 28, and the like) is provided.

  According to this configuration, since the wall-side rotary cleaning body 29 contacts the cleaning surface S only at the wall side, the wall-side rotary cleaning body 29 does not become a load when cleaning the normal cleaning surface S by the main rotary cleaning body 18. It is possible to reduce power consumption by reducing the load on the drive means (drive motor 21).

  Furthermore, in the suction inlet 10 of the embodiment of the present invention, the wall-side rotary cleaner 29 is driven to rotate in the forward direction. According to this configuration, the wall-side rotary cleaning body 29 rakes up dust on the wall toward the main rotary cleaning body 18, and rakes up the dust again by the main rotary cleaning body 18 to be sucked into the suction chamber 15. Can do.

  Furthermore, in the suction inlet 10 of the embodiment of the present invention, when the main rotary cleaning body 18 is driven to rotate in the forward direction, the main rotary cleaning body 29 is driven to rotate in the forward direction. Power transmission means 22 is provided for interlocking with the rotary cleaning body 18.

  According to this configuration, the main rotary cleaning body 18 is rotated in the forward direction, and the wall-side rotary cleaning body 29 is rotationally driven in the forward direction while the suction port body 10 is about to advance toward the wall 31 side. After the wall-side rotary cleaning body 29 comes into contact with the cleaning surface S near the wall by applying a moving force to move the suction port body 10 toward the wall 31 side, the suction-side mouth body 10 is also moved. Even if it is not pushed to the wall 31 side, the dust on the wall is more surely scraped up to the main rotary cleaning body 18 side by the rotary cleaning body 29 for the wall, and the scraped dust is scraped up again by the main rotary cleaning body 18. The suction chamber 15 can be sucked.

  Further, in the suction port body 10 of the embodiment of the present invention, the wall-side rotary cleaning body 29 is in direct contact with the main rotary cleaning body 18 and is driven to rotate by the rotation of the main rotary cleaning body 18. It has become.

  According to this configuration, the wall-side rotary cleaning body 29 can be driven to rotate with a simple configuration.

  Furthermore, in the suction port body according to the embodiment of the present invention, the wall-side rotary cleaning body 29 can move forward and backward with respect to the main rotary cleaning body 18 and contacts the wall 31 when the suction port body 10a moves forward.
