An embodiment of the present invention will be described below with reference to the drawings. This embodiment can be realized with a vacuum cleaner 1 having a cleaning head 10 for wiping. FIG. 1 is a perspective view schematically showing the appearance of a vacuum cleaner 1 according to this embodiment. A vacuum cleaner 1 is used to clean a floor 2, which is a kind of surface to be cleaned. For this purpose, the vacuum cleaner 1 has a cleaning head 10 , an extension tube 11 and a cleaner body 12 .

The cleaning head 10 has a head body portion 101 and a connection portion 102 that connects the head body portion 101 to the extension pipe 11 . The connecting portion 102 connects the cleaning head 10 to the cleaner main body 12 via the extension pipe 11 .

Here, the head main body 101 faces the floor 2 which is the surface to be cleaned, and by directing the corresponding surface toward the floor 2, a wiping system is established. Moreover, it is desirable that the cleaning head 10 and the extension tube 11 are detachable. Although not shown in FIG. 1 , the cleaning head 10 is provided with a rotating brush 103 that is a type of rotating cleaning body for wiping the floor 2 . In this embodiment, the rotating brush 103 is detachable from the head main body 101 and is made of a material with absorptivity.

Here, detachability can be realized by providing a connecting portion in the head body portion 101 and fitting it with the rotating brush 103 or removing it. Alternatively, it can be realized using a bearing such as a bearing, the details of which will be described in the examples below. Absorbency is a concept that includes so-called water absorption, oil absorption, and moisture absorption, and can be realized by porous materials such as sponges, fabrics such as towels, and those having absorbent resin. For this reason, the rotating brush 103 can be cleaned by simply removing it or squeezing it. Furthermore, by replacing the old rotary brush 103 whose performance has deteriorated, the absorption power, that is, the cleaning power for the floor 2 can be recovered. Thus, the present embodiment has the effect of improving maintainability. The details of the configuration for rotating the rotating brush 103 will be described in Examples below.

Further, the main body 12 of the cleaner, the extension pipe 11 and the cleaning head 10 each have a line for notifying commands of the operation buttons. The connecting portion 102 connects the lines of the extension tube 11 and the cleaning head 10 . As a result, the motor 104 that drives the rotating brush 103 is driven according to the command.

In addition, the head body 101 may have a suction path 108 that sucks dust on the floor 2 according to the suction force generated by the cleaner body 12 and causes the air containing the dust to flow from the connecting part 102 to the extension pipe 11 . desirable. However, the present invention does not necessarily require dust to be sucked. In other words, the extension tube 11 has a hollow structure, but instead of this, a rod-shaped portion having no hollow structure may be used. These can be referred to as sticks.

Air from the head main body 101 flows into the cleaner main body 12 via an extension pipe 11 which is a type of stick and is formed in a tubular shape. Here, a storage battery case 13 and a dust case 14 are connected to the cleaner main body 12 . That is, the cleaner main body 12 generates a suction force generated by the operation of the electric blower driven by the storage battery of the storage battery case 13 . Dust contained in the sucked air is collected in the dust case 14 . The details are described below.

The cleaner main body 12 has a cleaner main body portion 121 , a motor case portion 122 and a handle portion 123 for cleaning such as dust collection. Then, the extension pipe 11 is extended toward the main body 12 of the cleaner.

Here, the main body 121 of the cleaner is formed with a connection port to be connected to the extension pipe 11 . It is desirable that this connection port is formed of the same resin as cleaner main body 121, motor case 122, handle 123, and the like. Also, the connection port has a substantially circular opening and is formed facing forward. The connection port may be configured to connect the cleaning head 10 or other accessories other than the extension pipe 11, or the cleaner body 121 and the extension pipe 11 may be integrated. Furthermore, the cleaning head 10 may be configured integrally with the extension pipe 11 or configured integrally with the main body 121 of the cleaner.

Further, the motor case portion 122 is provided with an electric blower and a circuit board, and air containing dust is flowed into the dust case 14 by these functions. Then, clean air after being dust-collected by the dust case 14 flows into the motor case portion 122 . The electric blower is housed in the storage battery case 13 as described above and driven by the storage battery as a power source.

In order to execute the functions of the vacuum cleaner 1 including the above functions, the vacuum cleaner body portion 121 through the handle portion 123 are provided with operation buttons. Note that the cleaner main body portion 121 to the handle portion 123 has an operation portion, and an operation button may be provided here. The handle portion 123 is held by the user, and the electric vacuum cleaner 1 is moved according to the user's motion.

Furthermore, the vacuum cleaner 1 can be connected to a support base for charging the storage battery. Further, the electric vacuum cleaner 1 may have a structure in which power is appropriately supplied by a power cord instead of a storage battery. As described above, in the present embodiment, a so-called stick-type vacuum cleaner is exemplified as the vacuum cleaner 1, but the present invention is not limited to this. For example, in addition to the so-called canister type, it can also be applied to a robot cleaner.

As described above, the cleaning head 10 of the electric vacuum cleaner 1, which is an example of the cleaning device according to the present embodiment, has the rotating brush 103, which comes into contact with a cleaning surface such as a floor or a window to remove dirt. will do. Hereinafter, each example, which is a more specific aspect of the present embodiment, will be described. Note that the cleaning equipment is not limited to electric vacuum cleaners, and includes so-called mops and the like. Also, the rotating brush 103 may be wired according to the driving force of the motor 104, or may be rotated according to the movement of the cleaning device.

First, Example 1 is an example showing a configuration in which one rotating brush 103 is provided in the cleaning head 10 . Note that one rotating brush 103 is an example in which a row of rotating brushes 103 are provided in the moving direction, and a plurality of rotating brushes 103 may be provided in a horizontal direction to the moving direction, that is, in parallel.

The cleaning head 10 of this embodiment will be described below. FIG. 2 is a schematic front sectional view of the cleaning head 10 in this embodiment. In addition, the extension tube 11 is also shown in this figure. Also, the appearance of the electric vacuum cleaner 1 to which the first embodiment is applied is as shown in FIG.

In FIG. 2, the head main body 101 has a space with an opening facing the floor 2 (lower part of the drawing). This space is divided into spaces including the brush chamber 107 and the suction path 108 . The brush chamber 107 is a type of rotary cleaning member chamber, and a rotary brush 103, which is a type of rotary cleaning member, is provided therein. Along with this, a shaft portion 106 passing through the rotating brush 103 is provided in the brush chamber 107 . Here, the motor 104 and the bearing 105 are installed at both ends of the inner wall of the head main body 101, and the rotating brush 103 is provided through the shaft 106 therebetween.

By providing the brush chamber 107 in this manner, the interior of the brush chamber 107 and the space including the suction path 108 are not communicated with each other, that is, are isolated. Therefore, the rotating brush 103, the inner wall of the head main body 101, the motor 104 and the bearing 105 are separated and arranged. For this reason, it is possible to prevent dirt or liquid that is picked up from the floor 2 by the rotating brush 103 from being splashed onto the electrical system such as the motor 104 . That is, it is possible to prevent water leakage. Furthermore, it is possible to prevent these from hanging on the inner wall of the head body portion 101 . In addition to these, when the wet floor 2 is cleaned, the liquid may reach the blower of the cleaner body 12 and cause malfunction due to water wetting. Therefore, by providing the isolated brush chamber 107, it is possible to improve the maintainability of the electric vacuum cleaner 1 such as cleaning and repair. However, the brush chamber 107 may not be provided, and each of the components described above may be provided within the head main body 101 without being isolated.

Note that the motor 104 and the bearing portion 105 may be provided inside the brush chamber 107 . In this case, the motor 104 and the bearing 105 are installed at both ends of the inner wall of the brush chamber 107 . Even in such a configuration, it is possible to prevent dirt and the like from getting on the inner wall of the head main body 101 .

Further, the shaft portion 106 or the motor 104 and the bearing portion 105 pass through the wall of the brush chamber 107, and this through portion is sealed with a sealing material or the like.

In addition, the shaft portion 106 has an attachment/detachment mechanism that can be realized by a spring or the like at its end, so that the rotating brush 103 can be easily attached/detached from the head body portion 101 . A specific example of this attachment/detachment mechanism will be described later. Alternatively, the bearing portion 105 may be omitted, and the shaft portion 106 may be held by only one side in a so-called cantilevered manner. Also, instead of the motor 104 , bearing portions 105 may be provided on both sides, and a driving force other than the motor 104 may be used to rotate the rotating brush 103 . For example, rotation due to friction with the floor 2 accompanying the movement of the vacuum cleaner 1 may be used, or the flow of sucked air may be used. In these cases, a cooling mechanism, which will be described later, can be omitted.

The rotating brush 103 rotates according to the driving force transmitted from the motor 104 through the shaft portion 106 . As a result, the rotating brush 103 removes dirt and wetness from the floor 2 . Here, with reference to FIG. 3, the manner of rotational motion and the cooling of the motor 104 will be described. 3(a) and 3(b) are side sectional views of the cleaning head 10 in this embodiment. A rotating brush 103, which is a type of rotating cleaning body, contacts the floor 2 and rotates in the direction of the arrow. As a result, the floor 2 can be cleaned. For this reason, the shaft portion 106 rotates in accordance with the rotational motion of the motor 104 . Then, the rotating brush 103 rotates as the shaft portion 106 rotates. Since the rotating brush 103 has absorptivity, it absorbs the dirt and wetness of the floor according to this rotation. In addition, the cleaning head 10 moves in the horizontal direction in the drawing according to the user's operation. Thus, the vacuum cleaner 1 can clean the floor 2 as a whole.

As shown in FIGS. 3A and 3B, the rotation axis direction of the shaft portion 106 described here is horizontal with respect to the floor 2, which is the surface to be cleaned. Therefore, the rotating brush 103 rotates so as to involve the floor 2 . Therefore, the rotating brush 103 can take in dust and the like and more efficiently remove dirt.

By rotating the rotating brush 103, it is possible to apply a driving force that advances in the traveling direction. As a result, the cleaning head 10 has a self-propelled function, leading to improved operability of the cleaning device for the user.

As described above, in this embodiment, the motor 104 is used to rotate the rotating brush 103 . The motor 104 heats up according to its operation. It also has a substrate for operating the motor 104, which also heats up. Therefore, in this embodiment, a mechanism for cooling them is also provided. Specifically, the head main body 101 is provided with a cooling intake port 109 for taking cooling air into the head main body 101 . Cooling air taken in through the cooling air intake port 109 flows through the intake path 108 including the side of the motor 104 and the substrate, and is directed toward the extension pipe 11 . As a result, the motor 104 and the substrate can be cooled. Therefore, it is desirable to provide the cooling inlet 109 near the motor 104 . Further, regarding the motor 104, a storage battery may be provided in the vicinity thereof and used as a power source, or the storage battery in the storage battery case 13 may be used as a power source.

Here, in the present embodiment, the vacuum cleaner 1 can perform suction cleaning (so-called normal vacuum cleaner function) of sucking dust by sucking air, in addition to the above-described wiping. There are cases where it is desired to perform wiping cleaning and suction cleaning in parallel, and there are cases where one of them is desired to be performed. For example, if a large amount of liquid has been spilled on the floor 2, it is desirable to give priority to mopping, and if the floor 2 is damp and dust is scattered, it is desirable to perform these in parallel. Therefore, an example of switching between parallel execution and one execution will be described with reference to FIG.

FIG. 3(a) is a cross-sectional view of the cleaning head 10 during wiping. In contrast, FIG. 3(b) is a cross-sectional view of the cleaning head 10 during parallel execution. The cleaning head 10 is provided with a suction air adjustment valve 110 for adjusting the amount of suction air on the floor 2 . As shown in FIG. 3( a ), the suction air control valve 110 is installed at a position extending from the wall of the brush chamber 107 . In FIG. 3A, the suction air control valve 110 is closed, and wiping is performed without sucking air from the floor surface.

On the other hand, in FIG. 3B, the suction air control valve 110 is open, the suction air from the floor flows as indicated by the arrows, and suction cleaning and wiping are performed. The switching between FIGS. 3(a) and 3(b) can be controlled according to the user's designation for the operation button. Further, the suction air control valve 110 may be configured not only to open/close but also to adjust the amount of opening in multiple stages.

Also, when it is desired to perform only suction cleaning, it can be realized by stopping the rotation of the rotating brush 103 or raising its position to separate it from the floor 2 according to the user's designation on the operation button.

Further, when performing wiping cleaning, the suction force may be changed from the suction force used when performing suction cleaning, and the suction force may be suitable only for cooling the motor 104 . This enables efficient cooling of the motor 104 . The change in the suction force may be performed by an operation button, or may be automatically controlled when wiping is performed.

In this embodiment, the cleaning head 10 is controlled according to the type of cleaning to be performed, but it may be realized by exchanging the head. For example, the cleaning head 10 is prepared without the suction air control valve 110 or with the valve fixed in the closed state. When wiping cleaning is desired, the cleaning head 10 is connected to the extension pipe 11, and when suction cleaning is desired, a normal head is used. This concludes the explanation of switching between wiping cleaning and suction cleaning.

Next, one configuration example of the attachment/detachment mechanism for the rotating brush 103 will be described. FIG. 4A is a diagram showing one configuration example of the detachable rotating brush 103 and the shaft portion 106. FIG. FIG. 4A shows an example in which the shaft portion 106 is composed of a motor-side shaft portion 1061 and a bearing-side shaft portion 1062 .

Then, in FIG. 4A, the rotating brush 103 has a hollow portion 1031 . In this embodiment, the hollow portion 1031 is a through hole, but in the case of the cantilever structure described above, the hole on one side may be closed. The shaft portion 106 is inserted into this hollow portion 1031 . As a result, the rotating brush 103 also rotates according to the rotation of the shaft portion 106 .

Also, the motor-side shaft portion 1061 is composed of a motor-side mounting portion 611 , a motor-side shaft 612 and a tip portion 613 . Furthermore, the bearing-side shaft portion 1062 is composed of a bearing-side mounting portion 621 , a spring 622 and a bearing-side shaft 623 .

First, the motor-side mounting portion 611 is a mechanism that connects to the motor 104 and transmits its rotation to the motor-side shaft 612, and can be realized by gears, for example. Further, the motor-side shaft 612 has a non-circular cross-sectional shape. This is the shape for efficiently transmitting the rotational force to the bearing-side shaft portion 1062 into which it is inserted. In other words, if it is a circle (perfect circle), slippage and idling are likely to occur. For this reason, wasteful transmission of rotational force is likely to occur. Therefore, in this embodiment, the cross-sectional shape is made non-circular. A non-circular figure is a figure whose distance from a fixed point is not uniform, and the combination thereof suppresses idling like a circle. Non-circular shapes include ovals such as ellipses and eggs, polygons (including crosses), fan shapes such as semicircles and polygons combined, and Reuleaux polygons.

Further, the distal end portion 613 is pushed into the spring 622 when the motor side mounting portion 611 is inserted into the bearing side shaft portion 1062 . As a result, the motor-side mounting portion 611 and the bearing-side shaft portion 1062 are each pushed into the connection destination by the repulsive force of the spring 622, and the shaft portion 106 is fixedly installed.

It is desirable to use metal, plastic, or the like for each part of the motor-side shaft portion 1061 and the bearing-side shaft portion 1062 .

Next, the bearing-side shaft portion 1062 will be described. The bearing-side mounting portion 621 is fixedly connected to the bearing portion 105 and rotates the bearing-side shaft portion 1062 as the motor-side shaft portion 1061 rotates. The spring 622 is provided inside the bearing-side shaft 623 and exerts a repulsive force against the tip portion 613 . Moreover, the bearing-side shaft 623 has an axial hollow portion into which the motor-side shaft 612 is inserted. The cross-sectional shape of this shaft hollow portion is the same as that of the motor-side shaft 612 . That is, the cross-sectional shape of the shaft hollow portion is also non-circular. Therefore, the motor-side shaft 612 and the bearing-side shaft 623 are in close contact with each other, and the rotational force from the motor-side shaft 612 to the bearing-side shaft 623 is transmitted more efficiently.

FIG. 4B shows an external view of a combination of the rotating brush 103 and the shaft portion 106 composed of the motor-side shaft portion 1061 and the bearing-side shaft portion 1062 . As a result of being combined as shown in FIG. 4B, the repulsive force of spring 622 acts in the direction of the arrow in the figure. As a result, the motor side mounting portion 611 is firmly fixed to the motor 104 side. Although the motor 104 is configured independently in this embodiment, it may be configured to be incorporated in the motor-side mounting portion 611 . In this case, it is desirable to provide a mounting portion for mounting the motor side mounting portion 611 on the head body portion 101 .

Furthermore, in this embodiment and other embodiments, the shaft portion 106, particularly the portion inserted into the hollow portion 1031, is made of a material different from that of the rotating brush 103, such as metal, but the same kind of material may be used. In this case, it is desirable that the motor-side shaft 612, the tip portion 613, and the bearing-side shaft 623 are integrated to form a core portion. This core and the rotating brush 103 are integrally constructed. In this case, the rotating brush 103 disclosed in FIG. 4A constitutes the outer periphery with respect to the core. Further, it is desirable that the core portion is harder than the outer peripheral portion. In this form, it is desirable that the motor-side mounting portion 611 and the bearing-side mounting portion 621 are connected to both ends of the core.

This completes the description of the first embodiment. In Embodiment 1, the configuration in which one rotating brush 103 is provided in the cleaning head 10 is shown, but it is also possible to provide a plurality of rotating brushes 103 . An example of this will be described in Example 2.

Embodiment 2 is an example showing a configuration in which a plurality of rotating brushes 103 are provided in the cleaning head 10. FIG. It should be noted that a plurality of rotating brushes 103 means that a plurality of rotating brushes 103 are provided in the moving direction, and two rotating brushes 103 are provided in this embodiment. Except for the number of rotating brushes 103, Embodiments 1 and 2 have the same configuration and functions. Therefore, the difference from the first embodiment will be mainly described below.

FIG. 5 is a schematic side sectional view of the cleaning head 10 in this embodiment. In this embodiment, as the rotating brush 103, a rotating brush 103-1 and a rotating brush 103-2 are provided. During wiping, the rotating direction of the rotating brushes 103-1 and 103-2 is not limited, but it is desirable that they rotate in opposite directions. In particular, it is desirable that the direction of rotation is the direction of winding each other as shown. By rotating in the opposite direction as described above, dirt and the like can be removed more efficiently by rotating brush 103-1 and rotating brush 103-2.

Also, the rotary brush 103-1 and the rotary brush 103-2 may each have a configuration in which the number of rotations can be changed. By changing the number of rotations, it is possible to change the number of rotations to a suitable number depending on the dirt and the type of floor surface, improving the cleaning efficiency.

Further, the rotation of the rotating brushes 103-1 and 103-2 can apply a driving force to the cleaning head 10 in either direction. This makes it possible to provide a cleaning head that has a self-propelled function whether it is pushed or pulled. This self-propelled feature improves the operability of the cleaning appliance for the user.

Note that the number of rotating brushes 103 is not limited to two, and may be three or more. Further, in this embodiment, the rotating brushes 103-1 and 103-2 are arranged on the right side of the drawing so as to be close to the inner wall of the head main body 101. FIG. Therefore, the wall of the head main body 101 and the brush chamber 107 are partly shared. However, the arrangement is not limited to this, and the brush chamber 107 may be arranged in the vicinity of the center or in the front, or the walls of the head main body 101 and the brush chamber 107 may be configured independently. Furthermore, in the configuration of the second embodiment, the number of rotating brushes 103 is increased, so dirt and the like are easily scattered. Therefore, in the second embodiment, the effect of providing the brush chamber 107, that is, the prevention of water leakage is further improved.

Further, in this embodiment, the motor 104 may be provided for each rotating brush 103-1 and rotating brush 103-2, or may be shared by each. This completes the description of the second embodiment. According to the second embodiment, by increasing the number of rotating brushes 103, more powerful wiping becomes possible.

Next, in Example 3, a liquid is used to remove dirt from the floor 2 . The liquid may be liquid detergent, electrolyzed water (particularly, hypochlorous acid water), citric acid, or so-called water, as long as it exhibits detergency. Alternatively, the liquid may be sprayed onto the floor 2 or contained in the rotating brush 103 .

Below, hypochlorous acid water is used as the liquid, and a configuration in which the rotating brush 103 is made to contain the liquid will be described. FIG. 6 is a schematic front sectional view of the cleaning head 10 in this embodiment. In this figure, a water tank 31, an electrolytic section 32, a flow path 33 and an injection section 34 are added as compared with FIG.

First, salt water is stored in the water tank 31 . For this purpose, the water tank 31 is provided with an insertion port into which a user or the like puts in salt water. Then, the electrolysis unit 32 takes in the salt water in the water tank 31 through the water absorption pipe to generate hypochlorous acid water. For this purpose, the electrolytic section 32 is provided with electrodes and the like for performing electrolytic treatment. The power source of the electrolysis unit 32 may be the storage battery of the storage battery case 13 or the storage battery provided in the cleaning head 10 . Further, the operation of the electrolysis unit 32 is controlled by the user's operation of the operation button. Further, although not shown, a substrate for operating the electrolytic section 32 is also provided.

Then, the electrolyzer 32 discharges the generated hypochlorous acid water to the flow path 33 through the discharge pipe. Therefore, the hypochlorous acid water flows through the flow path 33 and reaches the injection part 34 . In response to this, the injection unit 34 injects the hypochlorous acid water onto the rotating brush 103 . As a result, the rotating brush 103 wipes the floor 2 while containing the hypochlorous acid water. Therefore, the cleaning power of the rotating brush 103 is improved. Although the hypochlorous acid water is sprayed onto the rotating brush 103 here, it may be sprayed toward the floor 2, that is, output. Also, the hypochlorous acid water may be output toward at least one of the rotating brush 103 and the floor 2 .

Furthermore, the water tank 31 and the electrolyzer 32 may be configured independently and detachably attached to the cleaning head 10 , or may be configured not to be detached from the cleaning head 10 . Further, of the water tank 31 and the electrolysis unit 32, at least the water tank 31 may be installed on the cleaner main body 12 side. In this case, the flow path 33 is also provided in the extension pipe 11 .

Furthermore, the injection unit 34 may output hypochlorous acid water, and may perform dripping or spraying. Alternatively, the rotating brush 103 and the injection section 34 or the flow path 33 may be directly connected. In this case, it is desirable to use a part on the brush instead of the injection part 34 .

According to the present embodiment, wiping cleaning using liquid can be realized, and the detergency can be further improved. In addition, if the liquid has a sterilizing effect such as hypochlorous acid water, the cleanliness of the floor 2, which is the surface to be cleaned, can be improved. This completes the description of the third embodiment.

Next, in Example 4, light is used for removing dirt from the floor 2 and for sterilization. Here, the light may have a sterilizing effect, and is preferably ultraviolet light (UV light).

FIG. 7 is a schematic front sectional view of the cleaning head 10 in this embodiment. In this figure, a light source section 41 is further provided as compared with FIG. The light source unit 41 is composed of a plurality of light sources and a substrate for controlling them. Each light source faces the floor 2, which is the surface to be cleaned. That is, the floor 2 is irradiated with UV light from each light source. Moreover, each light source is controlled to emit UV light according to the user's operation of the operation button. The power source of the light source unit 41 may be the storage battery in the storage battery case 13 or the storage battery provided in the cleaning head 10 .
