[0025] In addition, there are cases where multiple disclosures are collectively described as one embodiment. In addition, a part of the content described below is described as an arbitrary component related to the present disclosure.

[0026] (Embodiment 1)

[0027] Figure 1 FIG. 7 is a side view showing the vacuum cleaner system 100 of Embodiment 1. The vacuum cleaner system 100 generates a suction force by the rotation of a fan provided in the vacuum cleaner main body 101, and sucks dust and air together from the head 110. The sucked air and dust are separated inside the vacuum cleaner main body 101, and the air is discharged to the outside of the vacuum cleaner main body 101. In the case of the present Embodiment 1, as Figure 1 shown, the vacuum cleaner system 100 is a so-called canister-type vacuum cleaner, which includes a flexible hose 102 as a pipe member between the vacuum cleaner main body 101 and the head 110, a switch unit 104 having a grip portion 103 and being one of the pipe members, and a rigid pipe 105 as a pipe member integrated with wiring for supplying power to the head 110 and the like. The vacuum cleaner system 100 is supplied with power from a commercial power source in a wired manner.

[0028] Figure 2 FIG. 13 is a perspective view showing the head 110 provided in the vacuum cleaner system 100 from the suction port side. Figure 3 FIG. 15 is a perspective view showing the rotating member 123, the second electrode 122, and the friction body 125 with the head 110 omitted. The vacuum cleaner system 100 includes a head 110, a rotating member 123, a first electrode 121 (see Figure 4 ), a second electrode 122, a friction body 125, and a discharge power source 124 (see Figure 4 ).

[0029] In addition, the type of the vacuum cleaner system 100 is not limited to the canister type. For example, the vacuum cleaner system 100 may include a stick-type vacuum cleaner and a holding station for holding the stick-type vacuum cleaner. The stick-type vacuum cleaner includes a rigid pipe as a pipe member connected to the vacuum cleaner main body 101 and a head connected to the end of the pipe. Alternatively, the vacuum cleaner system 100 may include a robotic vacuum cleaner and a holding station for holding and charging the robotic vacuum cleaner. The robotic vacuum cleaner has the head 110 integrally assembled with the vacuum cleaner main body 101, and autonomously travels to automatically perform cleaning.

[0030] The head 110 includes: a cylindrical connecting portion 111 that is connected to the pipe 105; and a suction portion 112 that protrudes from the connecting portion 111 in both directions in a direction orthogonal to the pipe axis of the connecting portion 111.

[0031] The suction part 112 is a box-shaped structure with a hollow interior, and a suction port 113 for sucking dust is provided on the surface in contact with the floor. The suction port 113 is a rectangular opening extending along the length direction of the suction part 112. Inside the suction part 112, a rotating member 123, a first electrode 121, a second electrode 122, and a discharge power source 124 are arranged.

[0032] The rotating member 123 is a member with a friction body 125 mounted on its surface and rotating at the suction port 113. In the case of the present embodiment, the rotating member 123 is a cylindrical, conical, or rod-shaped member arranged inside the suction part 112 such that at least a part of the friction body 125 protrudes outward from the suction port 113. The rotating member 123 is arranged with its tube axis (central axis) along the axis extending in the length direction of the suction part 112 (Y-axis direction in the figure). By rotating around the tube axis, the friction body 125 sweeps the dust existing on the ground or the like and sucks the dust into the suction part 112.

[0033] The driving force for rotating the rotating member 123 is not limited. For example, the rotating member 123 can be rotated by a motor provided in the head 110 or the like, or can be rotated by the friction between the friction body 125 and the surface to be cleaned caused by the movement of the head 110.

[0034] Figure 4 This is a diagram showing an enlarged view of the position where the first electrode 121 and the second electrode 122 are close to each other. The friction body 125 is a member protruding from the surface of the rotating member 123 in a radial direction centered on the rotation axis of the rotating member 123. The friction body 125 rotates together with the rotating member 123, contacts the surface to be cleaned, and sweeps the dust toward the suction port 113. The type of the friction body 125 is not limited. For example, a belt-shaped non-woven fabric, a looped fabric, a sponge-like member, a soft tassel-like member formed of rubber or the like can be exemplified. In the first embodiment, the friction body 125 is resin-made bristles. The arrangement method of the friction body 125 is not limited, but in the case of the first embodiment, the friction body 125 is arranged in a spiral shape in a circle on the circumferential surface of the rotating member 123 from one end to the other end of the rotating member 123 in the rotation axis direction.

[0035] In addition, the rotating member 123 can also be combined with at least two of non-woven fabric, looped fabric, sponge-like member, rubber tassel, bristles, etc.

[0036] The first electrode 121 is an electrode disposed on the base end side of the friction body 125 that protrudes from the circumferential surface of the rotating member 123 in the radial direction centered on the rotation axis of the rotating member 123, that is, on the circumferential surface portion of the rotating member 123. The shape of the first electrode 121 is not limited, but in the case of the first embodiment, the first electrode 121 is in a strip shape, and is arranged in a spiral shape that encircles the circumferential surface of the rotating member 123 from one end portion to the other end portion of the rotating member 123 in the rotation axis direction at the position where the friction body 125 is disposed. By disposing the first electrode 121 in this way, the position where the first electrode 121 and the second electrode 122 are closest to each other can be repeatedly moved along the rotation axis by the rotation of the rotating member 123.

[0037] The second electrode 122 is an electrode disposed on the tip end side of the friction body 125 in the rotation locus of the friction body 125. In the case of the first embodiment, the second electrode 122 is a rectangular plate-shaped (strip-shaped) metal member that extends along the rotation axis direction of the rotating member 123 and is mounted parallel to the circumferential surface of the rotating member 123 on the head 110. The second electrode 122 is disposed to be in contact with a part of the tip end of the friction body 125 or to be close to a part of the tip end of the friction body 125 to a degree that can be regarded as contact, and the part of the second electrode 122 that is in contact with the friction body 125 or the like moves in the rotation axis direction by the rotation of the rotating member 123.

[0038] The discharge power source 124 is a device that applies a voltage between the first electrode 121 and the second electrode 122 and generates plasma between the first electrode 121 and the second electrode 122. In the case of this embodiment, local plasma can be generated locally in the second electrode 122, and charged particles such as free radicals, high-energy ions, and electrons can be generated.

[0039] The type of the discharge power source 124 is not limited, and it can be either a DC power source or an AC power source (including a pulse output power source). In the case of this embodiment, the discharge power source 124 is an AC power source. By applying an AC voltage between the first electrode 121 and the second electrode 122, dielectric barrier discharge (silent discharge) can be generated, and plasma can be generated while suppressing the generation of sparks and improving safety.

[0040] According to the vacuum cleaner system of the above-described first embodiment, the plasma can directly act on the friction body 125 sandwiched between the first electrode 121 and the second electrode 122, and the dirt on the friction body 125 to which oil or the like with high adhesiveness adheres can be decomposed and removed at high speed while cleaning, and in addition, bacteria, viruses, etc. attached to the friction body 125 can be sterilized and inactivated.

[0041] In addition, by rotating the rotating member 123, active species such as charged particles such as free radicals, high-energy ions, and electrons generated by the generation of plasma can be supplied to the surface to be cleaned, dirt such as oil adhering to the surface to be cleaned can be effectively decomposed and removed, and bacteria, viruses, etc. can be sterilized and inactivated.

[0042] In addition, by arranging the first electrode 121 in a spiral shape and making the second electrode 122 rod-shaped, it is possible to cause discharge only in the portion where the first electrode 121 and the second electrode 122 are close to each other. As a result, the electric power can be concentrated locally and discharge can be effectively generated, and the power consumption can be reduced.

[0043] (Embodiment 2)

[0044] Next, another embodiment of the vacuum cleaner system 100 will be described. In addition, there are cases where members (parts) having the same functions, functions, the same shape, mechanism, and structure as those of the above-described Embodiment 1 are denoted by the same reference numerals and the description thereof is omitted. In addition, hereinafter, the description will focus on the points different from Embodiment 1, and there are cases where the description of the same content is omitted.

[0045] Figure 5 It is a perspective view showing the vacuum cleaner system 100 of Embodiment 2. Figure 6 It is a perspective view showing the vacuum cleaner system 100 of Embodiment 2 in a disassembled state. Figure 7 It is a cross-sectional view showing the vicinity of the head 110 held by the holding station 130. In the case of the present Embodiment 2, as Figure 5 , Figure 6 shown, the vacuum cleaner system 100 includes a head 110, a rotating member 123, a first electrode 121, a second electrode 122, a friction body 125, a discharge power source 124, a holding station 130, and a selection device 140 (see Figure 8 , Figure 9 ). A rod-shaped vacuum cleaner 109 is composed of a vacuum cleaner main body 101, a head 110, and a rigid tube 105 as a pipe member that connects the vacuum cleaner main body 101 and the head 110.

[0046] The holding station 130 holds the vacuum cleaner 109 including the head 110. In the case of the present Embodiment 2, the holding station 130 is connected to a commercial power supply in a wired manner, and by holding the vacuum cleaner 109 having a battery (not shown), it also functions as a charging device capable of charging the battery of the vacuum cleaner 109.

[0047] In the case of Embodiment 2, the second electrode 122 is not arranged inside the suction portion 112 (details will be described later). In the present Embodiment 2, the friction body 125 is arranged on the front surface or substantially the front surface of the outer peripheral surface of the rotating member 123.

[0048] In the case of the second embodiment, the first electrode 121 is disposed at the position where the friction member 125 is disposed, that is, on the front surface of the outer peripheral surface of the rotating member 123 or substantially the entire outer peripheral surface. The first electrode 121 has a cylindrical shape.

[0049] In the case of the second embodiment, the second electrode 122 is mounted on the holding station 130 in such a manner that it is disposed on the tip side of the friction member 125 in the rotation trajectory of the friction member 125 in a state where the vacuum cleaner 109 is mounted on the holding station 130. As Figure 8 , Figure 9 shown, the second electrode 122 includes a plurality of divided electrodes 126 arranged along the rotation axis (Y axis in the figure) of the rotating member 123. The divided electrodes 126 are mounted on the holding station 130 in an insulated state from each other and constitute the second electrode 122 as a whole.

[0050] The selection device 140 is a switching device that selects one or more of the divided electrodes 126 to which a voltage is applied by the discharge power supply 124, and is capable of selecting whether to apply a voltage or not to each of the divided electrodes 126. There is no limitation on the timing, method, etc. for the selection device 140 to switch the selected divided electrodes 126. For example, the selection device 140 individually connects all the divided electrodes 126 and the discharge power supply 124, and can apply the voltage from the discharge power supply 124 to each of the divided electrodes 126 in sequence at a predetermined time interval, for example, apply it at a predetermined cycle while staggering the phases.

[0051] In the vacuum cleaner system 100 of the second embodiment, in a state where the vacuum cleaner 109 is mounted on the holding station 130, the rotating member 123 is rotated, and the divided electrodes 126 to which a voltage is applied are changed one by one. Thus, plasma can be uniformly generated with respect to the friction member 125 provided on the outer periphery of the rotating member 123. As a result, the dirt of the friction member 125 to which oil or the like adheres can be effectively decomposed and removed over a wide range, and in addition, bacteria, viruses, etc. adhering to the friction member 125 can be sterilized and inactivated.

[0052] Furthermore, the present disclosure is not limited to the above embodiments. For example, the constituent elements described in this specification can be arbitrarily combined, and in addition, other embodiments achieved by removing some constituent elements can be used as embodiments of the present disclosure. In addition, modification examples obtained by making various modifications conceived by those skilled in the art to the above embodiments within the scope not departing from the gist of the present disclosure, that is, the meaning indicated by the statements described in the claims, are also included in the present disclosure.

[0053] For example, as Figure 10As shown, the second electrode 122 may also be shorter than the first electrode 121 in the direction of the rotation axis of the rotating member 123 (the Y-axis direction in the figure), and is moved along the rotation axis (for example, reciprocating motion) by a driving device (not shown). By adjusting the movement of the second electrode 122 and the rotation of the rotating member 123, similarly to the case of Embodiment 2, plasma can be uniformly generated with respect to the friction body 125, the dirt on the friction body 125 to which oil or the like adheres can be decomposed and removed as a whole, and in addition, bacteria, viruses, etc. adhering to the friction body 125 can be sterilized and inactivated.

[0054] In addition, as Figure 11 , Figure 12 shown, a pneumatic supply device 150 may also be provided in the head 110. The pneumatic supply device 150 includes an axial fan, a sirocco fan, etc. that introduce air from the outside of the head 110 and supply air pressure from the inside of the head 110 toward the outside along the gap between the first electrode 121 and the second electrode 122. Thereby, an air flow from the inside of the head 110 toward the outside can be generated, the cleanliness of the friction body 125 can be improved, and at the same time, the decomposition of dirt and the inactivation of bacteria, etc. on the surface to be cleaned can also be performed.
