However, as disclosed in Patent Document 1, since the fabric member is attached to the rotary brush and installed, the fabric member must be peeled off from the rotary brush at the time of waste disposal, and the removing operation was troublesome. In addition, it is necessary to turn the suction port upside down and wind the fabric member on the rotating brush in a narrow case, and attach the adhesive subsidiary material carefully so as not to stick to the cylinder other than the rotating brush such as the suction inlet case. There was a problem that must be done.

Moreover, since what was disclosed by the said patent document 2 formed the separate blade part in front of the blade part of a rotating brush, it becomes a rotating brush of a complicated structure, and when the four blade consumes and replaces, it is necessary to replace the whole rotating brush. It could not be said that it was sufficient in terms of practicality, such as costly aspect and troublesome remounting of the rotary brush itself.

The present invention is based on the above-mentioned point, and by rotating the rotary brush, the adhesive sheet of the dust is automatically wound and mounted on the rotary brush, and the wiping cleaning and polishing effect exerted by the rotation of the mounted sheet is provided. An object of the present invention is to provide an electric vacuum cleaner which can be removed by appropriately controlling the rotational speed and the rotational direction of the rotating brush.

In the vacuum cleaner having a handle switch unit provided on the handle portion formed on the side, and a rotary brush, a drive motor for driving the rotary brush to rotate, and a floor suction port connected to the extension pipe, It is configured to be mounted on the rotary brush of the floor suction inlet, the knob switch portion is provided with a floor polisher mode switch, while controlling the drive motor in accordance with the operation of the floor polisher mode switch, the rotation It is most suitable for attaching the dust adsorption sheet and floor polishing by dust adsorption sheet which attached brush To a first control means for controlling a rotation speed.

Moreover, the 2nd control means which controls the rotation speed of the said electric blower, and controls to an optimal dust collection force at the time of shining a floor by a dust adsorption sheet is provided.

The floor suction switch is provided with a floor detection switch for detecting a contact state with the floor surface and for driving / stopping the drive motor.

In addition, a peeling part for engaging with the rear end of the seat is provided on the front surface of the main body case of the suction port, and a peeling mode switch is provided at the handle switch part, and the drive motor is controlled according to the operation of the peeling mode switch. And third means for controlling the rotary brush to a low speed reverse rotation suitable for removing the suction sheet.

1 to 3, the floor inlet 1 of the vacuum cleaner shown in FIG. 0 is a horizontally long inlet body case 2 having an inlet 6 widely opened from the upper case 2 a and the lower case 2 b to the front surface, and an inlet port. A rotating brush 3 freely supported by the bearing portion at both ends in the longitudinal direction of the main body case 2; It consists of the cover 5 which forms the front wall of the case 2, and opens and closes the front side part 6b of the inlet 6, and the bend 4 is connected to the cleaner main body through the extension pipe or hose which is not shown in figure. In addition, the groove formed on the bottom rear of the lower case 2 b is provided with a horizontally long bristle brush 90 so that it can be cleaned in contact with the surface to be cleaned. In addition, the brush 9000 has a structure that can be detached and detached from the case 2b. When the hair tip is dirty, the brush 90 can be detached from the lower case 2b and washed with water.

5 and 6, the rotary brush 3 has a plurality of longitudinally divided at an angle at which the brush body (or blade body) 8 is equally divided on the outer circumferential surface of the core 7, for example, at intervals of 9 0 ° or 6 0 °. It is formed spirally. A concrete installation method of the brush body 8 is to insert the root portion 8 b into a spiral groove formed on the outer peripheral surface of the core body 7. In addition, although not shown, the brush body 8 is configured such that the driving force is transmitted through the conduction belt or the like and rotated by the brush motor 110 built into the inlet body case 2. By rotating this brush body 8, the floor surface is scraped of dust and effectively sucked from the suction port 6 to be cleaned efficiently.

The cover 5, which is positioned close to the brush body 8 and covers the front part thereof, is not shown at both end sides in the longitudinal direction thereof, but an arm (ARM) part is integrally formed and rotated inside both ends of the main body case by the arm part. This is freely moistened. In addition, the cover 5 has a roller 9 which is operated to open the front part of the suction port 5 by rotating the cover 5 upward when the suction port front end touches the wall when cleaning the wall or the like. Rotation is freely mounted at a and 9 a. Here, the positional relationship between the rotational shaft of the cover 5 and the roller 9 is such that the cover 9 rotates upward when the roller 9 rotates counterclockwise when the roller 9 at the foremost part of the cover 5 touches a wall or the like. The cover 5 is set so as to be positioned above the rotational shaft, which is the rotational center of the shaft, thereby achieving the opening operation of the cover 5.

In addition, although the said cover 5 is not shown in figure, a spring (not shown) is attached to the rotating shaft as a biasing means which attaches to the direction which rotates the cover 5 downward. Therefore, in the case of normal floor cleaning in which the inlet front end does not touch the wall surface such as the wall side, the cover 5 closes the front part of the inlet 6 and only opens the lower part. When the cover 5 is heated, as shown in Fig. 9, the upper housing 2a part has a cavity accommodating recess 1 formed so as to finish the cover 5 from the rear end so as to have a structure to be housed inside the inlet body case 2. 0 is installed.

Since the roller 9 can also serve as a bumper for shock absorption when the front side of the inlet body case 2 touches an obstacle when the cleaner is turned, as shown in FIG. 10, the roller 9 has a rotating shaft 11. It is preferable that the outer circumferential surface of the cylindrical body 1 1 A is formed by being covered with a soft cloth slippery contact member and a fibrous member 11 d which is a fibrous member. At the same time, cover 5 can be rotated extremely smoothly. In addition, it is also useful that the left and right movements when the roller 9 is cleaned in the transverse direction in contact with the wall surface by the raising fabric 11 d are smooth.

In the present embodiment, the rotary brush 3 at the suction port 1 absorbs dust such as cloth or paper, for example, kitchen paper, as shown in FIG. 7 so that a cleaning method such as wiping and cleaning with a rag or the like is also possible. The adsorption | suction sheet 1 2 (henceforth "sheet") which can be wound up is made into the structure which can be wound up and attached automatically.

Next, the specific structure for attaching this sheet | seat 1 2 is demonstrated with reference to FIGS. First, as shown in FIG. 7, FIG. 1, etc., the order of sheet mounting places the long sheet 1 2 directly in front of the suction port 1, and raises the rotary brush 3 in the same shape on the end of the sheet 1 2. In this state, when the rotary brush 3 is rotated by inserting the operation switch of the cleaner, the sheet 1 2 is automatically entangled with the rotary brush 3 by the rotating brush 3 to be mounted. In addition, when the sheet is mounted, the rotary brush 3 is torn or controlled at an appropriate rotational speed.

Here, the conventional rotating brush 1 4 is a rotating brush of a general structure in which brush bodies 1 3 b of the same length are provided at regular intervals (in this case, 9 0.) Simply around the core 7 as shown in FIG. 2. There was a step D in the part with and without the brush body 1 3 b, and the sheet 1 2 was not evenly wound.

Moreover, even if it winds up, as shown in FIG. 2, the brush body 1 3b falls in the root part 1 3d by the winding of the sheet 1 2, and remains deformed after removing the sheet 1 2, and the brush body 1 3b There is a disadvantage that the dust scraping effect is worse.

In the case of the present invention, the rotary brush 3 A has a structure shown in Figs. 2 to 2 and 6, wherein two long and soft hair brushes 1 5 a are provided with two short and hard hair brushes 1 5 b on the outside. 1 brush body 1 5, the 2nd brush body 1 6 which installed the longest hair brush 1 6 a, and the 3rd brush body 1 7 which installed the 2nd long hair brush 1 7 a It is made of rotary brush 3 A. The first brush body 15 is arranged on the outer circumferential surface of the core 7 in a spiral form along the three-row axial direction at intervals of 1 2 0. The second brush body 1 6 and the third brush body 1 7 are the first brush body 1. Arranged in between, like 5.

FIG. 2: 6 shows how the sheet 1 2 is wound by this rotating brush 3A. When the front-end | tip of the sheet 1 2 contacts the rotating brush 3A, the sheet 1 2 will be accompanied by the brush 3A meeting. As it is sucked, it is entangled around the brush bodies 1 5 to 1 7. When the sheet 1 2 is entangled, the three kinds of brush bodies 1 5 to 1 7 are each deformed (bend method) in accordance with the hardness (softness) of the hair, and the hair tips thereof as shown in Fig. 2 5. 1 2 The sheet 1 2 is kept in a round shape without distortion by contacting the inner surface without difficulty. As a result, the sheet 1 2 is rolled up in a rounded state. Moreover, in the 1st brush body 15, the outer hair | bristle brush 15a of the hair | bristle tip in which the upright state was maintained hits the inner surface of the sheet | seat 1 2 at right angles. In this case, three first brush bodies 1 5 are provided at intervals of 1 20 0. Thus, a situation in which the three brush bodies 1 5 uniformly support three points on the inside of the sheet 1 2 as a whole is a sheet 1 2. It helps to keep the grip on the ground. Moreover, since the short brush body 15b in the 1st brush body 15 is not related to the entanglement with the sheet | seat 1 2, the disadvantage that the root like the conventional brush body 3b is bent does not generate | occur | produce, either.

In addition, even when the preceding second and third brush bodies 1 6 and 1 7 are bent, any kind of the first to third brush bodies widen the gaps on both sides (as if filling the gaps). Since the brush bodies 1 5 to 1 7 each receive the stress from the sheet 1 2 and are bent at an appropriate angle, the brush bodies 1 5 to 1 7 are extremely deformed so that the root of the brush body 1 3 b as in the prior art is extremely bent. The brush body 1 5 to 1 7 is extremely bent and the photonic effect is not lost. In addition, around the core 7, a plurality of brushes three of five kinds of brush bodies 1 5 to 7 in total are arranged evenly, and the step D between the brush body and the brush body is removed to form a rotating brush 3A. The tension of the sheet 1 2 can be retained and wound.

The rotary brush 3B shown in FIG. 2 7 is another embodiment which enables sheet winding. In this case, ribs 1 8 and 1 8 were installed in the core 7 of the rotary brush 3B. Ribs 1 8 and 1 8 are two leg-shaped shapes opened in an arm shape in the outward direction and are integrally formed to protrude integrally with the outer circumference of the core 7 so as to exist between the brush body 1 9 and the brush body 1 9. . The ribs 18 and 1 8 are formed concentrically with the core 7 and the length is set to a length shorter than that of the brush body 1 9. Thus, in the rotary brush 3B with ribs 1 8 and 1 8 to fill the space 20 between the brush bodies 1 9, the ribs 1 8 and 1 8 are wound around the sheet 1 2 like the conventional rotary brush 1 4. The step difference between the part with and without the brush body which obstructs is removed, and the sheet 1 2 is wound around uniformly.

In the method shown in FIG. 8, the sheet 1 2 may be wound on the rotary brush 3.

That is, the sheet 1 2 is press-fitted by the brush 3 which rotates the sheet 1 2 from the space | interval 2 2 between the case 1 front surface of the inlet 1, and the roller 9 provided in the said case 1 by the rotating brush 3. In this case, the sheet 1 2 has an average length of the entire front edge of the sheet 1 2 by the roller 9 which is long enough for the width of the sheet, and the left and right are guided by the roller 9 so that 9 rotates. As a result, the front surface of the sheet 1 2 is sent evenly pulled out, so that the sheet 1 2 is uniformly wound around the rotary brush 3. For this reason, when the sheet 1 2 described above is injected into the rotary brush 3 in the inlet 6 just below the inlet 1, the seat 1 2 is sometimes misaligned when the seat 1 2 and the rotary brush 3 are set. The problem is that it becomes attached to the diagonal line and the wiping effect cannot be sufficiently obtained. The drawback of sheet 1 2 where the front edge of sheet 1 2 is creased and starts to be wound. It is advantageous to be able to eliminate the disadvantage that the end flows down and touches the floor, causing noise, and so on by the guide action of the roller 1 2.

In the case of not letting out the sheet 1 2 using the roller 9, the raising cloth 2 3 is attached to the roller 9 as shown in FIG. This is because if roller 9 is a roller with low resistance such as resin, roller 9 will slip when guiding sheet 1 2 and it will be difficult to obtain the desired uniform winding effect. have. When a member having a resistance such as a raising fabric 2 3 is formed on the outer circumference of the roller 9, the contact resistance between the roller 9 and the sheet 1 2 becomes stronger, the entire sheet is unevenly spread, which makes it possible to send it more reliably and smoothly. The sheet 1 2 can be evenly wound on the rotary brush 3 in the inlet 6.

In this way, as shown in FIG. 7, FIG. 1 etc., the sheet | seat 1 2 is wound up by the rotating brush 3 of the said structure, and is rotated, and the floor surface dirt and dust are wiped off by the sheet 1 2 reliably. It also adds a glow effect, so you can clean the floor.

On the other hand, it is necessary to remove the sheet 1 2 when the wiping cleaning is finished and the dirty sheet 1 2 is discarded, or when the new sheet 1 2 is replaced and replaced. Sheet 1 2 may be removed by hand. As shown in FIG. 9, the free end 1 2 d of the wound end of the sheet 1 2 wound on the rotary brush 3 in the suction port 6 can be pulled forward by a finger, and removed by hand. Alternatively, by rotating the rotary brush 3, as shown in Fig. 1, the front end portion of the seat 5 comes into contact with the front end 5d of the cover 5, and the sheet 1 2 is naturally detached from the rotary brush 3 as if the sheet 1 2 is released. In this case, the rotating brush is reversed as described later.

In addition, when removing the sheet 1 2, as described above, when the cover 5 is opened and closed up and down to form the front wall of the inlet body case 2, the sheet 1 2 is easily taken out. Although the cover 5 is closed by a spring or the like, as shown in Fig. 9, when the cover 5 is moved in the longitudinal direction and opened like a shutter by being stored in the main body case by manual operation, the inlet 6 is only lowered before the cover opening operation. And change from a small opening in a situation that is difficult to pull out to a large opening that is also open in the front. For this reason, it becomes easy to touch a sheet 1 2 from the opening 6b of a front side part, and it becomes possible to grasp the sheet 1 2 and to remove it easily.

Moreover, when this sheet 1 2 is wound by the rotating brush 3, it is so convenient that the state of the winding can be confirmed easily. That is, as shown in FIG. 1, the front part of the inlet body case 2 is formed of a transparent member such as the transparent part 1 2 A, or as shown in FIG. 2 4, 2 4 should be installed on the left and right sides. The hole 2 4 may be a transparent window covered with a transparent member so that dust does not enter. In this way, knowing that sheet 1 2 is wound properly, you can rewind it and refit it if it is not wound properly.

In addition, when the rear end of the sheet 1 2 as shown in FIG. 1 5 is cut in an oblique line to form a triangle, or the rear end of the sheet 1 2 is cut in an M shape as shown in FIG. 1 6, the end of the sheet 1 2 is used. This disturbance reduces the amount of seam hitting the floor.

That is, when the general rectangular sheet is wound and operated as the sheet, the rear part (the wound end) of the sheet is disturbed or the end of the sheet is sucked into the suction port, so that the joint is generated. On the other hand, if the front is triangular or M-shaped like the sheet 1 2, the sheet fragments 1 2 b, 1 2 c, and 1 2 c have a small front area that is in contact with the floor surface or the case (intake body case). As a result, the phenomenon of tapping the floor surface at the end as in the conventional long sheet is eliminated, so that the occurrence of abnormal sounds is suppressed. In addition, disturbance (flapping) of the sheet edge part is also suppressed.

1 to 7 show another sheet in which the winding end of the sheet 1 2 is not wrinkled and wound.

In the sheet 1 2 of FIG. 1 7, the string 2 5 was attached to the front end of the sheet 1 2 (the end of the winding) by sewing or bonding. In this case, the string 2 5 is entangled in the front end part by being entangled with the arbitrary brush bodies 8 of the rotating brush 3 as shown in FIG.

In the sheet 1 2 of FIG. 1 9, a hard material such as wire 2 6 is sewn on the tip, and the end (the end of the winding) is formed into a rigid structure, that is, a hard edge 2 7. With this configuration, at the time of seat mounting, the front end of the seat is pulled out by the wires 2 6 and the like, the front end is not wrinkled, and is attached to the rotary brush 3 in a uniform state, and is stably wound.

In addition, in the case of FIG. 20, the wheel of the string 2 8 is provided in the both sides of the front-end part of the sheet | seat 1 2. On the other hand, the hook 2 9 which catches the wheel of the string 2 8 of the rotating brush 1 2 side is formed in the core 7. By this structure, as shown in FIG. 2, the wheel of the string 2 8 is caught by the hook 2 9, and it is wound uniformly in order from the front-end part. Besides, it is also possible to stop the end of the sheet 1 2 on the core of the rotary brush 3 by using a removable tape.

Thus, by providing the locking means at the end of the sheet 1 2, the front edge of the sheet 1 2 can be wound around the rotary brush 3 in a uniform and stable state.

In this way, the shape of the sheet 1 2 is deformed or the attaching means to the rotating brush 3 is provided so that the sheet 1 2 is easily wound, but the brush body (blade) 8 of the rotating brush 3 is shown in FIGS. 5 and 20. Similarly, in the case of a spiral in one direction, when the sheet 1 2 is wound or wound and the operation is continued, the sheet 1 2 may be oriented on one side to reduce the wiping effect and the floor polishing effect.

In view of this point, in installing the brush body (blade) 8 around the core 7, as shown in FIG. 2 8, the brush body (blade) 8 is arranged in a V shape when the core 7 is viewed horizontally. It is good. That is, it is preferable to make the brush body (blade) 8 into the shape wound around the core 7 in one direction diagonal toward the center part of an axial direction, and to arrange | position it in the shape wound around the core 7 with the reverse oblique line in the center part.

In this way, the sheet 1 2 wound in contact with the surface of the brush body 8 receives a connection resistance from the brush body 8 in a V-shape by the rotation of the rotary brush 3, but the sheet 1 2 is pulled together as a resistance component. Force occurs from side to side. This prevents the disadvantage that sheet 1 2 is moved to one side. Therefore, it can be wound up and hold | maintained in the regular position of the sheet | seat 1 2 even during rotation, and the wiping cleaning and a glossiness effect can fully be acquired.

Fig. 9 shows the configuration in which the guide ribs 30 which cause the same sheet pulling action are provided on the main body case 2 side, and the inner wall surface 2D of the main body case 2 (upper case 2a) is wrapped around the upper portion of the brush. Guide ribs 30 of the shape along the rotational accumulation are formed. And this guide rib 30 is arrange | positioned and formed in the V shape like opening in both directions from the axial longitudinal center part of the rotating brush 3. In addition, the guide rib 30 is formed by setting the length so that the tip may protrude so that the tip may contact the sheet 1 2 wound around the rotary brush 3. The sheet 1 2 is guided by the guide ribs 30 provided in such a form, and the component force acting in the direction of pulling the sheet 1 2 is generated by the contact resistance generated when the sheet 1 2 comes into contact with the sheet 1 2. As a result, the tensioned state can be preserved not only during the winding of the rotating sheet 1 2 but also after the winding, and the core 7 is no longer shifted laterally, and is wound and held at the normal position. For this reason, the wiping cleaning and polishing effect can be obtained as in the case where the tip brush body 8 is arranged in a V shape.

Next, the control regarding the rotation brush 3 of this invention is demonstrated with reference to FIGS.

As shown in FIG. 3, the vacuum cleaner includes a vacuum cleaner body 3 4 incorporating an electric blower 3 3 (see FIG. 3) for dust collection, a flexible hose 3 5A connected to the vacuum cleaner body 3 4, and a vacuum cleaner. An extension pipe 3 5 B connected to the flexible hose, a handle switch part 3 8 shown in FIG. 3 2 provided on a handle part 3 7 formed on the extension pipe connection side of the flexible hose 3 6, and a rotary brush 3, corresponding rotation. A drive motor 40 (see FIG. 3 3), which drives the brush 3 to rotate, is built in and comprises a floor suction port 1 connected to the extension pipe 3 5 B.

As shown in Fig. 2, the knob switch 3 8 stops operation of the operation switch for performing various operations, for example, a strong switch 4 1 for strengthening a suction capability, a weak switch 4 2 for weakening, and a cleaner operation. Switch 4 4, floor polisher 4 4, and paper peeling switch 4 5 are installed.

When the steel switch 4 1 is pressed, the electric blower 3 3 is rotated at a high speed to increase the suction capacity of the cleaner. When the switch 4 2 is pressed, the electric blower 3 3 rotates at a low speed, and the vacuum cleaner suction capability is weakened.

When the changeover switch 4 3 is operated, the electric blower 3 3 is stopped, and the drive motor 40 0 which rotates the rotary brush 3 is also stopped to completely stop the operation of the vacuum cleaner.

In addition, the floor polishing mode switch 4 4 is operated when wiping and cleaning is performed by attaching a sheet 1 2 capable of adsorbing dust such as kitchen paper to the rotary brush 3 as described later. The drive motor 3 8 is driven at the rotational speed (low speed) which is optimal for mounting of the sheet 1 2, and the rotary brush 3 is rotated. Thereby, the sheet 1 2 is automatically wound by the rotation brush 3 according to the rotation.

Moreover, even after sheet mounting, the rotation brush 3 is rotationally controlled at the optimum rotation speed (low speed) which can perform floor polishing (wiping) well at the time of operation of the said floor polishing mode switch 4 4. This makes it possible to clean the floor and clean the floor, and to avoid the situation that the rotational balance that collapses in the seat mounting becomes strong at high speed and is easy to pick up, and can be operated quietly.

In addition, the peeling switch 4 5 operates when the sheet 1 2 is removed from the rotary brush 3, and at the time of operation, the drive motor 40 is reversed at a rotation speed (low speed) that is optimal for automatically peeling off the sheet 1 2. To rotate the rotary brush 3 in reverse.

However, the bottom of the floor suction port 1 detects whether the suction hole 1 is in the cleaning state by contacting the floor surface 2 4 and whether the suction port 1 is apart from the floor surface 2 4 and is not in the cleaning state. The floor detection switch 4 6 (FIG. 3) is provided. In this case, the floor detection switch 4 6 is a structure that operates on a vertically movable wheel 4 7, which is generally biased downward by an elastic member such as a spring, and the wheel 4 7 of the inlet 1 is grounded on the floor 2 4 and resists the spring. When it moves upward, it turns on and rotationally drives the drive motor 40 of the rotary brush 3. When the wheel 4 7 protrudes downward with a force away from the floor 2 4, the wheel 4 7 is turned off to stop the drive motor 40. The rotary brush 3 rotates when the suction inlet 1 is attached to the floor 2 4, and stops when the suction port 1 is removed from the floor 2 4, and is folded to the floor 2 4 of the floor inlet 1. Automatically start / stop control of rotary brush 3.

The floor suction port of this structure is operated and controlled by the control circuit shown in FIG. The microcomputer 4 8 inputs the operation signals from the switches 4 1 to 4 6, and according to the input signals, the microcomputer 4 8 uses the drive motor 4 0 or the electric blower 3 3 as the brush motor drive circuit 4 9 and the suction motor drive circuit, respectively. Operation control through 5 0.

3 4 shows a control flow controlled by the control circuit. Next, the control method will be further described by this control flow.

From the start of the flow, control according to the state of each switch is executed. Since it is now floor cleaning, when the sheet 1 2 is attached to the rotary brush 3 and wiping and cleaning, the floor polishing mode switch 4 4 is pressed (process 5 1). When the floor gloss mode switch 4 4 is pressed, the drive motor 40 is rotated and controlled by the microcomputer 4 8 and the brush motor drive circuit 4 9 at the optimum rotation speed for the seat 1 2 (process 5 2). For this reason, the sheet 1 2 is wound around the rotating brush 3 to automatically mount the sheet 1 2. Performing this control is the first control means.

At this time, the electric blower 3 3 rotates at the optimum speed by the suction motor drive circuit 50 (process 5 3). The situation where the suction force which does not affect the mounting of the sheet is weakened is preferable. Performing this control is the second control means.

In this way, the floor surface 2 4 is cleaned with the suction port 1 which attached the sheet 1 2 to the rotating brush 3. At this time, ON / OFF of the detection switch 4 5 is judged (Judges 5 4) and when the floor detection switch ON where the inlet 1 reaches the floor 2 4 (Judges 5 4 y) continues the processing 5 2, 5 3. The sheet 1 2 can be wiped and cleaned continuously at an optimum (low speed) rotation state.

On the other hand, when the inlet 1 is temporarily separated from the floor 2 4 and is in the off state, the floor detection switch 4 6 is turned off (decision 5 4 n), and the drive motor 4 0 is stopped (process 5 5). . For this reason, since the rotary brush 3 which attached the sheet | seat 1 2 stops frequently when it falls from the floor surface 2 4, the operation noise at the time of wiping and cleaning can be reduced.

Next, when removing the soiled sheet 1 2, press the peeling switch 4 5. When the corresponding switch 4 1 is pressed (process 6 1), the drive motor 4 0 is controlled by the microcomputer 4 8 and the brush motor drive circuit 4 9 in reverse rotation control at the optimum rotation speed (low speed) for removing the sheet (process 6 2). ). When the rotary brush 3 starts to rotate at low speed, as shown in FIG. 1, the free end 1 2d of the full end of the sheet 1 2 touches the tip 5d of the cover 5. After touching, the cover tip 5d acts to slowly peel off the sheet 1 2 by the further rotation of the rotary brush 3, and finally the sheet 1 2 is completely peeled off and is automatically removed. Performing this control is the third control means.

The switches 3 8, 3 9, etc. are operated during normal cleaning operation by rotating the rotary brush 3 to scrape off the dust without attaching the sheet 1 2. The suction force at which the high speed rotation (process 7 3) and the low speed rotation (process 7 4) are performed turns into strong and weak. Moreover, drive control of the drive motor 30 is performed based on ON / OFF operation | movement by the floor detection switch 46. At this time, when the inlet 1 of which the floor detecting switch 4 6 is turned ON (judge 7 5y) is placed on the floor 2 4, the drive motor 4 0 is controlled to rotate at high speed by the brush motor drive circuit 4 9 (processing). 7 6) Drive by scraping garbage.

When the changeover switch 4 3 is pressed (process 8 1), the electric blower 3 3 and the drive motor 40 0 are stopped (process 8 2, 8 3) and the operation of the vacuum cleaner is stopped at all.

When the floor wiping mode switch 4 4 is pressed, the changeover switch 4 3 is operated, and the operation of the other operation switches 4 1, 4 2, 4 5 is not received unless the cleaner operation is stopped. As a result, since the normal rotary brush 3 rotates at a high speed while the sheet 1 2 is attached and does not enter the operation to scrape off dust, the rotary brush 3 does not operate even if the operation switches 4 1 and 4 2 are inadvertently operated. Thus, the seated sheet 1 2 is not damaged.

As described above, the floor suction inlet 1 is sucked and cleaned from the suction inlet which scrapes dust with the rotary brush 3 by rotating the vacuum cleaner without attaching the sheet 1 2 to cleaning the tatami carpet or the like. On the other hand, when the floor surface is cleaned, such as flooring, the sheet 1 2 is wound around the rotary brush 3 so that the floor surface is wiped and cleaned by the sheet 1 2 which rotates integrally with the brush, and the floor polishing effect is also achieved. can do.

As described above, according to the present invention, when the sheet capable of adsorbing dust is attached to the rotary brush in the suction port, the rotary brush is properly controlled at the rotational speed at which the sheet is easily mounted by the operation of the floor polisher mode switch. It can be mounted automatically without tearing the sheet. Moreover, since it is controlled by an appropriate rotational speed even after sheet | seat mounting, it is a vacuum cleaner which is low in noise, and can rub the floor surface, the scraping of rubbish, and the floor polishing well.

At the same time, the suction force of the electric blower is also appropriately controlled so as not to suck the sheet strongly, so that the seat is easily mounted.

In addition, when the floor is polished, the rotary brush operates and stops depending on whether it is raised or dropped by the floor detection switch installed at the lower part of the suction port. Less.

In addition, there is a peeling switch to operate when the sheet is removed by the rotating brush. By operating this, the rotating brush is rotated backward at a suitable low speed when the rotating brush is wound and unwound, so that it can be detached automatically and the work such as sheet replacement is easy. It's convenient.
