Moreover, the supply part 43 sucks up electrolyzed water in the water supply pipe connecting the storage part 41 and the supply part 43 by its water absorption. In other words, the vacuum cleaner 1 supplies electrolyzed water to the suction air passage 13 by bringing a water-absorbing member into contact with the electrolyzed water. Even if the suction air passage 13 is positioned higher than the storage portion 41, the supply portion 43 can suck up and move the liquid by capillary action. By changing the degree and size of water absorption of the supply portion 43, it is possible to adjust the sucking power and height and avoid oversupply. Note that the supply unit 43 may be arranged below the storage unit 41 and the electrolyzed water generator 42 .

The supply part 43 integrally having a member made of a superabsorbent polymer can hold more target electrolyzed water.

When the supply unit 43 is provided in the downstream air passage 13d, the supply unit 43 evaporates electrolyzed water in the suction air passage 13 between the dust separation and dust collector 7 and the electric blower 8 to separate the dust. Electrolyzed water can be supplied to the dust collector 7 . Evaporation of the electrolyzed water proceeds until the vapor pressure of the gas in the suction air passage 13 reaches the saturated vapor pressure. The vaporized electrolyzed water reaches the dust separation and dust collection device 7 through the suction air passage 13 and sterilizes the dust accumulated in the dust separation and dust collection device 7 . When the supply unit 43 is provided in the downstream air passage 13d, the electrolyzed water should be vaporized while the electric blower 8 is stopped in order to sterilize the dust accumulated in the dust separation and dust collector 7. is preferred.

Further, when the supply unit 43 is provided in the downstream air passage 13d, the exhaust gas from the electric blower 8 can be sterilized by evaporating the electrolyzed water while the electric blower 8 is being driven. In other words, when the supply unit 43 is provided in the downstream air passage 13d, the entire amount of vaporized electrolyzed water is supplied to sterilize the exhaust air blowing out from the cleaner body 2 while the electric blower 8 is being driven. Dust accumulated in the dust separating/dust collecting device 7 can be sterilized while the device is in use and the electric blower 8 is stopped.

On the other hand, when the supply unit 43 is provided in the upstream air passage 13u, the supply unit 43 vaporizes the electrolyzed water by the flow of air sucked from the suction port, and supplies the electrolyzed water to the dust separation and dust collector 7. be able to.

It is preferable that there is a portion with an inner diameter smaller than that of the supply unit housing portion 61 on the upstream side of the supply unit housing portion 61 . In other words, the supply section housing section 61 bulges outward in the radial direction of the suction air passage 13A.

Further, the depth of the supply unit accommodating portion 61 (difference in inner diameter from other portions of the suction air passage 13A) is determined by the exposed surface 43a of the supply portion 43 exposed to the suction air passage 13A and the other portion of the suction air passage 13A. It is preferable that the depth be flush with the inner surface 13a of the . Further, the depth of the supply section housing section 61 may be such that the exposed surface 43a of the supply section 43 is arranged radially outward of the inner surface 13a of the other portion of the suction air passage 13A.

If the supply unit 43 were arranged so as to block the airflow flowing through the suction air passage 13A, it is conceivable that a large amount of dust would adhere to the supply unit 43 . Therefore, in the vacuum cleaner 1D, the exposed surface 43a of the supply portion 43 is arranged flush with the wall surface of the suction air passage 13A, or the exposed surface 43a of the supply portion 43 is positioned closer to the suction air passage 13A than the wall surface of the suction air passage 13A. dust is prevented from adhering to the supply portion 43 by keeping it away from the center line of the supply portion 43 .

FIG. 10 is a schematic diagram of the suction air passage of the vacuum cleaner of the sixth example according to the embodiment of the present invention.

As shown in FIG. 10, the suction air passage 13B of the vacuum cleaner 1E (sixth example of the vacuum cleaner) according to the present embodiment has a supply section housing as a space opened toward the downstream side of the suction air passage 13B. A partition plate 63 that partitions the portion 61B and accommodates the supply portion 43 in the supply portion accommodation portion 61B is provided.

It is preferable that there be a portion having an inner diameter smaller than that of the supply portion housing portion 61B on the upstream side of the supply portion housing portion 61B. In other words, the supply section accommodating section 61B bulges outward in the radial direction of the suction air passage 13B. It is preferable that the depth of the supply section accommodating section 61B is such that the exposed surface 43a of the supply section 43 is arranged radially outward of the inner surface 13a of the other portion of the suction air passage 13B.

The partition plate 63 extends from the upstream side toward the downstream side of the supply section accommodating section 61B. Then, the partition plate 63 opens the supply section accommodating section 61B toward the downstream side of the suction air passage 13B. That is, the upstream end of the partition plate 63 is connected to the inner surface 13a of the suction air passage 13B, and the downstream end of the partition plate 63 is separated from the inner surface 13a of the suction air passage 13B. Further, the partition plate 63 hides the supply section accommodating section 61B when viewed from the center line C of the suction air passage 13B. Moreover, the partition plate 63 hides the supply portion 43 when viewed from the center line C of the suction air passage 13B.

A surface 63a of the partition plate 63 on the suction air passage 13B side (that is, a surface 63a facing the center of the suction air passage 13C) is continuous with the inner surface 13a of the suction air passage 13B on the upstream side of the partition plate 63 . Since the surface 63a of the partition plate 63 on the suction air passage 13B side and the inner surface 13a of the suction air passage 13B are continuous with each other, disturbance of the flow on the downstream side of the partition plate 63 is suppressed, and dust is prevented from entering the supply unit housing portion 61B. Intrusion is also restricted.

The flow of air in the suction air passage 13B follows the surface 63a of the partition plate 63 on the suction air passage 13B side from the upstream side of the partition plate 63 . Therefore, it is difficult for the flow of air in the suction air passage 13B to flow around the supply section accommodating portion 61B that is opened toward the downstream side of the suction air passage 13B. Also, dust carried by the air is less likely to enter the supply section accommodating section 61B. Therefore, the vacuum cleaner 1</b>E can prevent dust from adhering to the supply portion 43 .

FIG. 11 is a schematic diagram of a suction air passage of a seventh example of the vacuum cleaner according to the embodiment of the present invention.

As shown in FIG. 11, the suction air passage 13C of the vacuum cleaner 1F according to the present embodiment (seventh example of the electric cleaning device) is designed to supply electrolyzed water to the suction passage 13C depending on the presence or absence of dust in the suction passage 13C. It has a switching mechanism 71 for switching the supply state of .

When dust passes through the suction air passage 13C, the switching mechanism 71 cuts off ventilation between the suction air passage 13C and the supply unit 43 to block the supply of electrolyzed water into the suction air passage 13C, In other cases, that is, when the electric blower 8 is stopped and no suction negative pressure is generated, the supply part 43 is exposed to the suction air passage 13C to enable the supply of electrolyzed water into the suction air passage 13C. .

The switching mechanism 71 has a larger inner diameter than the other portions of the suction air passage 13C, and permits or blocks ventilation between the supply portion housing portion 61C that houses the supply portion 43, and the supply portion housing portion 61C and the suction air passage 13C. A door portion 72 that can be opened and closed, and a dust detector 73 (an example of dust detection means) that is provided in the suction air passage 13C upstream of the supply portion 43 and detects the presence or absence of dust passing through the suction air passage 13C. and an open/close drive unit 75 that opens and closes the door unit 72 based on the detection result of the dust detector 73 .

It is preferable that there is a portion having an inner diameter smaller than that of the supply portion housing portion 61C on the upstream side of the supply portion housing portion 61C. In other words, the supply section accommodating section 61C bulges outward in the radial direction of the suction air passage 13C. It is preferable that the depth of the supply section accommodating section 61C is such that the exposed surface 43a of the supply section 43 is arranged radially outward of the inner surface 13a of the other portion of the suction air passage 13C.

The door portion 72 is provided at the boundary portion between the suction air passage 13C and the supply portion accommodating portion 61C. The door portion 72 is preferably a sliding door, for example. A sliding door makes it easier to secure a space required for opening and closing than a hinged door. The door portion 72 may be a sliding door that can be opened and closed by moving in the flow direction of the suction air passage 13C, or a sliding door that can be opened and closed by moving in the circumferential direction of the pipe defining the suction air passage 13C. Also good. The door portion 72 may be a sliding door that opens toward the upstream side of the intake air passage 13C, or may be a sliding door that opens toward the downstream side of the intake air passage 13C. As an example, the door portion 72 opened toward the downstream side of the suction air passage 13C is indicated by a chain double-dashed line. The sliding door that opens toward the downstream side of the intake air passage 13C can be opened more reliably by utilizing the flow of air due to the intake negative pressure. The sliding door that opens toward the upstream side of the suction air passage 13C can be closed more reliably by utilizing the flow of air due to the suction negative pressure when closing.

Further, the door portion 72 may be a bellows-type shutter. The shutter can save more space in the area required for opening and closing than the sliding door.

It is preferable that the surface 72a of the door portion 72 on the intake air passage 13C side (that is, the surface 72a facing the center of the intake air passage 13C) is continuous with the inner surface 13a of the intake air passage 13C on the upstream side of the door portion 72. . Since the surface 72a of the door portion 72 on the suction air passage 13C side and the inner surface 13a of the suction air passage 13C are continuous, disturbance of the flow on the downstream side of the door portion 72 is suppressed, and the resistance when opening and closing the door portion 72 is reduced. can be suppressed.

When the door portion 72 is closed, it blocks air flow between the suction air passage 13C and the supply portion housing portion 61C, and when it is opened, it permits air flow between the suction air passage 13C and the supply portion housing portion 61C. When the airflow between the suction air passage 13C and the supply portion accommodating portion 61C is cut off, the electrolyzed water vaporized from the supply portion 43 is not supplied to the suction air passage 13C. When airflow between the suction air passage 13C and the supply portion accommodating portion 61C is permitted, the electrolyzed water vaporized from the supply portion 43 is supplied to the suction air passage 13C.

The dust detector 73 detects the presence or absence of dust passing through the suction air passage 13</b>C and outputs the result to the opening/closing control section 77 . The dust detector 73 detects the presence or absence of dust by detecting a change in the amount of light crossing the suction air passage 13C. The dust detector 73 includes, for example, a light-emitting element and a light-receiving element that detects light emitted by the light-emitting element. The dust detector 73 detects the presence or absence of dust by detecting the frequency and time when the light emitted from the light emitting element is blocked by the dust passing through the suction air passage 13C with the light receiving element. Since the dust detector 73 detects the presence or absence of dust with light, the presence or absence of dust can be detected without increasing the pressure loss of the suction air passage 13C.

The opening/closing driving section 75 includes a driving source for opening and closing the door section 72 , such as an opening/closing electric motor 76 , and an opening/closing control section 77 for controlling the operation of the opening/closing electric motor 76 .

The opening/closing electric motor 76 transmits driving force for opening and closing the door portion 72 via, for example, a gear provided on the output shaft and a rack provided on the door portion 72 .

The open/close control unit 77 receives a detection result as to whether or not dust is passing through the suction air passage 13C from the dust detector 73 . The opening/closing control portion 77 operates the opening/closing electric motor 76 to close the door portion 72 when dust is passing through the suction air passage 13C. Further, the opening/closing control section 77 operates the opening/closing electric motor 76 to open the door section 72 when dust does not pass through the suction air passage 13C. When the door portion 72 is opened, the supply portion 43 is exposed to the suction air passage 13C.

Electric cleaning device 1F cannot supply electrolyzed water to suction air passage 13C while dust is flowing in suction air passage 13C compared to electric cleaning devices 1D and 1E. You can definitely prevent sticking.

As described above, the vacuum cleaners 1, 1A, 1B, 1C, 1D, 1E, and 1F according to the present embodiment use the electrolyzed water generated by the electrolyzed water generator 42 as the suction air connected to the suction side of the electric blower 8. A supply 43 is provided to supply the channels 13, 13A, 13B, 13C. Therefore, the vacuum cleaners 1, 1A, 1B, 1C, 1D, 1E, and 1F supply electrolyzed water to the suction air passage 13 to continuously sterilize the dust accumulated in the dust separation and dust collector 7, and clean it. It is possible to continuously disinfect the exhaust air of the machine body 2 .

Further, the vacuum cleaners 1, 1A, 1B, 1C, 1D, 1E, and 1F according to the present embodiment are provided with a supply unit 43 that vaporizes electrolyzed water and supplies the electrolyzed water to the dust separation dust collector 7. . Therefore, the vacuum cleaners 1, 1A, 1B, 1C, 1D, 1E, and 1F can supply vaporized electrolyzed water to the intake air passages 13, 13A, 13B, and 13C. The vaporized electrolyzed water easily diffuses through the intake air passages 13, 13A, 13B, and 13C, continuously disinfects the dust accumulated in the dust separation and dust collector 7, and continuously exhausts the air from the cleaner body 2. disinfect.

By the way, in a conventional vacuum cleaner equipped with a sterilization device that can be attached to the suction port of the vacuum cleaner main body, electrolyzed water is added to a paper pack with the sterilization device attached to the suction port of the vacuum cleaner body instead of the pipe part. supply. In other words, the conventional vacuum cleaner cannot remove dust accumulated in the paper pack during cleaning, that is, during operation of the electric blower.

On the other hand, the vacuum cleaners 1, 1A, 1B, 1C, 1D, 1E, and 1F according to the present embodiment vaporize the electrolyzed water by the flow of air sucked from the suction port 28, and the electrolyzed water is supplied to the dust separation and dust collector 7. is provided with a supply unit 43 for supplying the In other words, the vacuum cleaners 1, 1A, 1B, 1C, 1D, 1E, and 1F vaporize electrolyzed water from the supply unit 43 while the electric blower 8 is in operation. Therefore, the vacuum cleaners 1, 1A, 1B, 1C, 1D, 1E, and 1F vaporize the electrolyzed water in a state where there is substantially no air flow in the intake air paths 13, 13A, 13B, and 13C. A larger amount of electrolyzed water can be vaporized.

In addition, when the supply unit 43 is provided in the downstream side air passage 13d, the electric cleaners 1, 1A, 1B, 1C, 1D, 1E, and 1F are fine dust that passes through the dust separating and collecting device 7. The exhaust gas from the electric blower 8 that contains or has an odor can be sterilized with electrolyzed water that evaporates in a larger amount. Furthermore, in the vacuum cleaners 1, 1A, 1B, 1C, 1D, 1E, and 1F, when the supply unit 43 is provided in the upstream air passage 13u, dust is sucked into the dust separation and dust collector 7, and The dust accumulated in the dust separating/dust collecting device 7 can be sterilized with the electrolyzed water that vaporizes in a larger amount.

Furthermore, the vacuum cleaners 1A, 1B, and 1C according to the present embodiment are provided with a heat source 51 that promotes vaporization of electrolyzed water. Therefore, the vacuum cleaners 1A, 1B, and 1C can vaporize a larger amount of electrolyzed water than at room temperature (environmental temperature at which the vacuum cleaner 1 is used).

A vacuum cleaner 1A according to this embodiment includes a heating element 52 that converts electricity into heat as a heat source 51 . The heating element 52 can be easily arranged anywhere in the intake air passage 13 as long as the electric power can be supplied. Therefore, the vacuum cleaner 1A can easily arrange the supply portion 43 and the heat source 51 along the suction air passage 13 .

The vacuum cleaners 1B and 1C according to this embodiment use at least one of the electric blower 8 and the body control unit 9 as the heat source 51 . Therefore, the vacuum cleaners 1B and 1C can suppress power consumption for raising the temperature of the heat source 51 compared to the vacuum cleaner 1A.

A vacuum cleaner 1</b>D according to this embodiment includes a heat transfer section 53 that transfers heat from the heat source 51 to the supply section 43 . Therefore, the vacuum cleaner 1D can secure a heat transfer path between the supply portion 43 and the heat source 51 as the heated portion. In other words, the vacuum cleaner 1D can improve the degree of freedom in arranging the supply portion 43 and the heat source 51 respectively.

Further, the vacuum cleaners 1, 1A, 1B, 1C, 1D, 1E, and 1F according to the present embodiment are provided with a supply portion 43 having irregularities 46 that are exposed to the suction air passage 13. As shown in FIG. The unevenness 46 increases the surface area relative to the projected area of the supply portion 43 and increases the amount of electrolyzed water vaporized from the supply portion 43 . A larger amount of electrolyzed water promotes sterilization of dust in the dust separating/dust collecting device 7 and exhaust air from the electric blower 8 .

Furthermore, the vacuum cleaners 1, 1A, 1B, 1C, 1D, 1E, and 1F according to the present embodiment are provided with a supply portion 43 capable of ventilating the air in the suction air passage 13. As shown in FIG. The air-permeable supply part 43 increases the surface area relative to its projected area, thereby increasing the amount of electrolyzed water vaporized from the supply part 43 . A larger amount of electrolyzed water promotes sterilization of dust in the dust separating/dust collecting device 7 and exhaust air from the electric blower 8 .

Further, the vacuum cleaner 1D according to the present embodiment includes a supply portion accommodating portion 61 that has a larger inner diameter than other portions of the suction air passage 13A and accommodates the supply portion 43 . The supply unit accommodation unit 61 prevents dust flowing through the suction air passage 13</b>A from adhering to the supply unit 43 . Therefore, the vacuum cleaner 1</b>D can prevent the amount of electrolyzed water vaporized from the supply portion 43 from decreasing.

Furthermore, the vacuum cleaner 1E according to the present embodiment has a partition plate 63 that partitions the supply portion accommodating portion 61B that is opened toward the downstream side of the suction air passage 13B and that accommodates the supply portion 43 in the supply portion accommodating portion 61B. I have it. The partition plate 63 hides the supply section accommodating section 61B when viewed from the center line of the suction air passage 13B. In other words, the supply portion 43 accommodated in the supply portion accommodation portion 61B is exposed to the air in the suction air passage 13B, but is less likely to be exposed to dust sucked toward the downstream side of the suction air passage 13B. Therefore, the vacuum cleaner 1</b>E can prevent reduction of the electrolyzed water vaporized from the supply portion 43 .

Further, the vacuum cleaner 1F according to the present embodiment includes a switching mechanism 71 that switches the supply state of electrolyzed water to the suction air passage 13C depending on the presence or absence of dust inside the suction air passage 13C. When dust is passing through the suction air passage 13C, the switching mechanism 71 cuts off ventilation between the suction air passage 13C and the supply unit 43 to block the supply of electrolyzed water into the suction air passage 13C. Further, when the electric blower 8 is stopped and the suction negative pressure is not generated, the switching mechanism 71 exposes the supply portion 43 to the suction air passage 13C and supplies electrolyzed water into the suction air passage 13C. Therefore, the vacuum cleaner 1</b>F can reliably prevent dust from adhering to the supply portion 43 , and can prevent reduction of electrolyzed water vaporized from the supply portion 43 .

Therefore, according to the vacuum cleaners 1, 1A, 1B, 1C, 1D, 1E, and 1F according to the present embodiment, accumulated dust can be sterilized without taking time to attach and detach, and exhaust air can be sterilized. Can be continued easily.
