Reference numeral 11 denotes a cleaner main body having a built-in electric blower 11a, and a suction port 12 is connected through a hose 16 and an extension pipe 17 connected to a suction unit 14a provided in the dust collection unit 14. That is, dust and the like on the floor surface 13 are sucked from the suction port 12 by the suction force of the electric blower 11a, and the dust is separated and accumulated in the dust collecting unit 14.
[0016]
FIG. 2 is a cross-sectional view of the horizontally long suction port 12. FIG. 3 shows a view of the suction port 12 from the top, and FIG. Reference numeral 21 denotes a rotating brush driven by an electric motor or an air flow, has a brush on its surface, and wipes and sweeps the floor. Reference numeral 22 denotes a sponge-shaped soft water absorbing body, which is detachably attached to an attaching portion 28 on the bottom surface of the mouthpiece 12. Reference numeral 23 denotes a water supply tank to which a water supply pipe 24 provided with a water supply nozzle 25 at one end is connected. The water supply nozzle 25 is provided with a nozzle hole 25b having a nozzle opening / closing valve 25a. A tank opening / closing valve 27 opens and closes the flow of water from the water supply tank 23 to the water supply pipe 24.
[0017]
When the soft water-absorbing body 22 is attached to the mounting portion 28 on the lower surface of the mouth, the upper end of the soft water-absorbing body 22 pushes up the nozzle opening / closing valve 25a, and the nozzle hole 25b is opened, as shown in FIG. Next, when the tank opening / closing valve 27 is opened, the water in the water supply tank 23 is supplied to the soft water absorbing body 22. The nozzle hole 25b is minute, and when the water contained in the soft water-absorbent body 22 is small, the water moves by the water-absorbing power of the soft water-absorbent body 22, but when the water increases and the water-absorbing power becomes small, the water naturally flows from the nozzle hole 25b. The supply of water is stopped, and the water content of the soft water absorbing body 22 is maintained at an appropriate constant amount. By moving the suction opening 12 on the floor surface 13 in a state where appropriate water is absorbed by the soft water absorbing body 22, the floor surface is wiped with appropriate water. In addition, the suction force causes the suction airflow indicated by the arrow 30a to flow on the floor, wipe the water, and at the same time dry the floor 13, so that the floor 13 is not excessively wetted and the floor is not damaged.
[0018]
The set value of the amount of water supplied to the soft water absorbing body 22 can be changed depending on the size and number of the nozzle holes 25b and the opening degree of the nozzle opening / closing valve 25a. Also, by controlling the opening and closing of the tank opening / closing valve 27, the amount of water supplied to the soft water absorber can be varied. Alternatively, it is also possible to provide an air vent hole 29 in the water supply tank and open and close the air vent hole cover 29a to vary the flow rate of water. Of course, if a pump or the like is installed in the water absorption path, the water supply amount can be accurately controlled over a wider range. By adjusting the amount of water absorption manually or automatically, it is possible to obtain a water amount suitable for the type of the floor 13 and the purpose of wiping and cleaning, and more comfortable wiping becomes possible. When the soft water absorbing body 22 is removed, the nozzle on / off valve 25a automatically closes, and cleaning for normal dry dust can be performed. The dirty soft water-absorbing body 22 can be used repeatedly if it is removed and washed with water. The water supply tank 23 can also be detached from the mouthpiece 12 main body, so that water supply and maintenance can be easily performed.
[0019]

After attaching the soft water absorber 42, the lid 43c of the water supply port 43a is opened to supply water, and the lid 43c is attached again, and then attached to the bottom surface 12a of the suction port 12. The water in the water supply tank 43 permeates an appropriate amount into the soft water absorbing body, and the soft water absorbing body 42 appropriately containing water enables the floor surface to be wiped and cleaned. As for the maintenance, the water supply tank 43 and the soft water absorber 42 are integrated, so that the handling is easy. If the soft water absorbing body 42 integrated with the water supply tank 43 is removed from the suction port 12 as shown in FIG. 7B, general cleaning using the rotating brush 21 can be performed. If the lid shown at 44 is attached to the bottom surface 12a, air does not flow in from the portion where the soft water absorbing body 42 is removed, and the suction force does not decrease.
[0022]
Further, as shown in FIG. 8, when performing general cleaning, a configuration in which an integrated water supply tank and a soft water absorbing body are housed in a suction body may be considered. FIG. 8A shows a state in which the soft water absorbing body 42 is housed in the mouthpiece 12 and general cleaning is possible.
[0023]
(Example 3)
FIG. 9 shows a configuration in which the soft water absorbing body 52 can be stored in the main body. A soft water-absorbing body 52 fixed to a guide frame 53 is slidably mounted on the mounting portion 12b of the suction opening 12 in a vertical direction. Reference numeral 53a denotes a stopper, which normally protrudes outward due to the preload of the spring 53c, but has a configuration in which it is accommodated inward by applying a small force. When the soft water absorbing body 52 is pulled out as shown in FIG. 9A, the soft water absorbing body 52 is fixed to the inlet 12 by the brim portion 53b of the guide frame 53 and the stopper 53a at a position where the soft water absorbing body 52 comes into contact with the floor surface 13. When the soft water absorbing body 52 is pushed upward, the stopper 53a retracts and slides upward, and as shown in FIG. 9B, the upper end of the soft water absorbing body 52 contacts the nozzle opening / closing valve 25a, and the stopper 53a comes to the upper end of the mounting portion 12b. It is fixed in a hung state and stored in the suction opening 12.

In this embodiment, when the soft water absorbing body 52 shown in FIG. 9B is stored in the mouthpiece 12, water penetrates from the water supply tank 25 into the soft water absorbing body 52, and the soft water absorbing body 52 shown in FIG. When the floor 13 is wiped with water by moving it downward until it reaches the surface 13, it is configured so that it can be used in a state where a suitable amount of moisture has been obtained. That is, during the water wiping cleaning shown in FIG. 9A, the water supply is stopped, and the excessive moisture is prevented from moving to the floor surface 13. Reference numeral 27 denotes a tank opening / closing valve for controlling a water supply amount. Contrary to this configuration, it is also possible to adopt a configuration in which water is supplied when the soft water absorbing body 52 is taken out and the floor surface 13 is wiped with water, and when supplied, the water supply is stopped. A configuration in which the amount of water supplied is controlled by the tank opening / closing valve 27 in a state where water can be supplied from the tank 25 is also possible.
[0025]
FIG. 10 shows an example in which the soft water absorbent 52 is moved in and out in conjunction with the foot pedal 57. The foot pedal 57 rotates around the rotation shaft 57a, and moves the soft water absorbing body 52 up and down via the connecting rod 57b.
[0026]
FIG. 11 shows an example of the soft water-absorbing body 62 in which the lid 62a is attached to one side surface. The soft water-absorbing body can be housed in the mouthpiece body by rotating around a rotation shaft 62b formed on the lid 62a. In addition, when stored, it is possible to prevent the storage portion from being closed by the lid 62a and foreign matter from entering. FIG. 11A shows a state in which the soft water absorbing body 62 is stored, that is, a state in which normal cleaning is performed, and FIG. 11B shows the state in which the soft water absorbing body 62 is turned to the outside so that the floor surface is wiped with water.

(Example 4)
12 and 13 show an example in which the front of the soft water absorber 72a and the rear of the soft water absorber 72b are attached to the front and back of the bottom surface of the mouthpiece 12, and when the mouthpiece moves forward by the action of the moving wheel 73, When 72b comes into contact with the floor surface and moves backward, the front of the soft water-absorbing body comes into contact with the floor surface. Since the soft water absorbers are installed before and after, the water can be wiped and cleaned at the corners such as near the wall, and when moving forward, between the front of the soft water absorber 72a and the floor surface 13, and when moving backward, after the soft water absorber. Because there is a gap between the floor 72b and the floor 13, even relatively large dust can be sucked. In addition, since a gap with the floor surface 13 is always ensured, a large air volume can be wiped and cleaned, the floor surface 13 can be dried quickly, and the floor surface is not easily damaged. FIG. 13 shows a view of the mouthpiece 12 from the bottom. Further, a soft water-absorbing body is arranged around the mouthpiece 12 for efficient wiping and cleaning of the corners, and when operating by the suction mouth 12, the front part is lifted when the front part is moved backward, and a gap with the floor surface 13 is generated. A configuration or a configuration in which a soft water-absorbing body is arranged in the entire mouth 12 and air flows in from the upper surface of the mouth to dry the floor 13 can be considered.
[0028]
When an antibacterial agent is mixed with water, antibacterial action on the floor surface can be performed, and bacteria do not propagate on the soft water absorbent. It is also possible to adopt a configuration in which an antibacterial agent is mixed into a soft water-absorbing material and gradually dissolved by water.
[0029]
It is also possible to mix a floor protective lubricant, a polishing agent, and the like. As the material of the soft water absorbent, many types such as a porous resin such as urethane foam, a nonwoven fabric, and a fibrous cloth can be considered.
