  Although the dust roll of the suction tool for a conventional vacuum cleaner (wiping roller of the present invention) can be removed and cleaned, the cleaning of the wipe roll is not always sufficient, and the water is retained. The water itself is likely to corrode, but the water held in the rag roll is contaminated by dust or dirt wiped off by the rag roll, which accelerates the corrosion and causes microorganisms such as bacteria to grow and cause sliminess. . When such a state worsens, a bad odor is generated from the dust roll. In addition, when the rag roll is reused in such a state, dirty water is applied to the cleaning floor surface, and there is a disadvantage that an unsanitary situation occurs.

  The present invention has been made in order to solve the above-described problems. In the situation where the wiping roller is not cleaned after completion of the wet wiping cleaning, the wiping roller can be used in the wiping roller even under an environmental condition where the wiping roller is difficult to dry. A vacuum cleaner suction tool that can keep the wiping roller clean by suppressing corrosion of the retained water and making the water retained on the wiping roller antibacterial and wiping the floor surface in a clean state is obtained. For the purpose. Moreover, it aims at obtaining the vacuum cleaner which has such a suction tool.

  The vacuum cleaner suction tool according to the present invention includes a suction port, a suction path between the suction port and a suction side connection portion of the vacuum cleaner body, a wiping roller, a wheel that facilitates movement during forward movement and backward movement. Etc., and the wiping roller has a roller body that retains moisture on the outer surface side, and when the wiping roller retains water in the roller body, the wiping roller makes the antibacterial water by contacting with the antibacterial agent possessed. The antibacterial water is used as the water retained in the roller body.

  The wiping roller of the suction tool for the vacuum cleaner of the present invention, when holding water, makes the water antibacterial water by contacting with the antibacterial agent held therein, and the antibacterial water is used as holding water for the roller body. Corrosion of water held by the wiping roller can be suppressed and kept clean even in an environment that is difficult to dry without sufficient cleaning after wiping and cleaning. Further, in wet wiping, the floor surface is wiped with water having antibacterial action, so that clean wiping can be performed.

Mounted rotatably. The connection pipe 4 is connected to the suction side of a vacuum cleaner main body (not shown) via a bellows hose and an extension pipe.
Further, a suction path 5 is provided between the upper case 2 and the lower case 3, and a suction port 6 is formed in the front surface of the lower case 3 at the tip of the suction path 5 over the longitudinal direction. A front wheel 6 a is disposed in the vicinity of both front ends of the suction port 6, and a blade 7 is disposed in parallel with the suction port 6 behind the suction port 6.

Further, a roller storage chamber 8 is formed at the center of the lower surface of the lower case 3, and is formed in a space substantially independent of the suction path 5 and the suction port 6. A wiping roller 9 is provided in the roller storage chamber 8. The wiping roller 9 includes a cylindrical roller shaft 15 and a roller body 13 that covers the outer surface of the roller shaft 15.
A bearing 11 is formed on one end of the roller storage chamber 8 so as to prevent the support shaft 10 of the wiping roller 9 from rotating, and a roller removal door assembly 12 is provided on the other end to remove the roller. A door assembly shaft portion 12a (hereinafter referred to as a door assembly shaft portion 12a) is inserted into a roller inner bearing 14 formed on the inner surface of the roller body 13 of the wiping roller 9, and is pivotally supported. A bearing support shaft 17 is inserted into the inner surface of the roller shaft 15, and a unidirectional rotary bearing 18 is provided in the bearing support shaft 17. A connecting rod 19 connected to the support shaft 10 is pivotally supported by the unidirectional rotary bearing 18 on the side opposite to the bearing 11.

Accordingly, the wiping roller 9 is supported by removably inserting the support shaft 10 into the bearing 11 on one side, and supported by removably fitting the door assembly shaft portion 12a in the roller inner bearing 14 on the other side. Further, the unidirectional rotation between the connecting rod 19 connected to the support shaft 10 on one side and the unidirectional rotary bearing 18 and the rotation between the roller bearing 14 and the door assembly shaft portion 12a on the other side are unidirectional. Rotate, but not in the opposite direction.
Further, the roller removal door assembly 12 can be opened and closed. By opening the roller removal door assembly 12, the wiping roller 9 becomes detachable, and the roller inner bearing 14, the bearing support shaft 17, the unidirectional rotary bearing 18, the connecting rod 19, the support shaft 10 and the antibacterial agent eluting body 16 can be integrally taken out and the wiping roller 9 can be cleaned.

Further, a water flow hole 14 a passes through the bottom surface of the roller inner bearing 14 on the side opposite to the insertion side of the door assembly shaft portion 12 a so that water can flow into the space in the roller shaft 15. The roller shaft 15 has a plurality of water discharge holes 15 a for discharging water flowing into the roller body 13 to supply water to the outer roller body 13. FIG. 5 shows a water discharge hole 15 a provided in the roller shaft 15.
The roller body 13 can be dry-wiped and cleaned if it is made of, for example, a brushed cloth, but if it is made of a water-absorbing sponge or the like, the roller body 13 can be wet-wiped and cleaned by retaining water.

A cylindrical antibacterial agent eluting body 16 is accommodated inside the cylindrical roller shaft 15.
One end of the antibacterial agent eluting body 16 is supported by a bearing support shaft 17 inserted into the roller shaft 15, and the other end is supported by the roller inner bearing 14 (see FIG. 4).
The antibacterial agent eluting body 16 is formed by, for example, depositing silver (Ag) on the surface of a non-corrosive material such as aluminum, stainless steel, or ceramics to form a coating 16a, and the silver (Ag) coating 16a as the antibacterial agent becomes moisture. It is conceivable to control silver ions (Ag +) so that a very small amount of silver ions (Ag +) is eluted from the coating, or to adjust the dissolution by molding an inorganic / organic antibacterial agent. Further, the shape and form may be a stick having a long cylindrical shape, a ball shape, a granular shape, a powder shape, or the like.

  Further, a movable arm 20 is pivotally supported on the lower case 3 by a movable arm shaft 21 at the rear portion of the lower surface of the case 3. A rear wheel 22 is rotatably supported on the movable arm 20. Here, the positional relationship between the connecting pipe 4 and the rotating shaft 4 a is such that the movable arm shaft 21 is arranged in front of the rotating shaft 4 a of the connecting pipe 4 and the rear wheel 22 is arranged behind the rotating shaft 4 a of the connecting pipe 4. A movable spring 23 is sandwiched between the lower case 3 and the movable arm 20 so that the movable arm 20 including the rear wheel 22 has elasticity within a predetermined range.

Next, the operation will be described.
Due to the suction action of the main body of the vacuum cleaner (not shown) to which the suction tool 1 is connected, most of the dust passes from the suction port 6 of the suction tool 1 through the suction path 5 and through the connection pipe 4, via a bellows hose and an extension pipe (not shown). Collected in the dust collection chamber of the vacuum cleaner. At that time, the blade 7 disposed in parallel to the rear of the suction port 6 prevents the inflow of air from the rear of the suction tool 1 main body, prevents the suction force from the suction port 6 from being reduced, and reduces the suction force. Dust and the like are prevented from flowing out rearward from the mouth 6 and dust adhesion to the roller body 13 of the wiping roller 9 is reduced.

  The suction tool 1 cleans the floor surface by a cleaning operation that repeatedly advances and retreats on the floor to be cleaned. When the suction tool 1 moves forward, the suction tool 1 sucks dust by the suction action of the main body of the vacuum cleaner. The rotation of the wiping roller 9 at the time of advancement is stopped by the action of the unidirectional rotating bearing 17 in the wiping roller 9 installed in the wiping roller 9, and the roller body 13 is compressed by the pressing action by the forward operation of the suction tool 1. As the surface is moved, the fine dust left by suction cleaning is surely wiped off the cleaning floor.

  Further, when an operating force is applied from the direction of the connecting tube 4 through the proximal portion of the bellows hose and the extension tube (not shown) by the forward movement operation of the suction tool 1, the movable device sandwiched between the movable arm 20 and the lower case 3. Cleaning that applies an operating force from the direction of the connecting pipe 4 until the outer periphery of the roller body 13 of the wiping roller 9 comes into contact with the surface to be cleaned due to the suspension effect of the movable arm 20 and the rear wheel 22 due to the compression action of the spring 23. Reduces the burden on the arm of the worker and shock.

  On the other hand, when the suction tool 1 is retracted, dust is sucked by the suction action of the main body of the vacuum cleaner, and the wiping roller 9 is rotated by the unidirectional rotating action of the unidirectional rotating bearing 18 in the wiping roller 9. The rotation of the wiping roller 9 is a series of forward and backward cleaning operations. By stopping and rotating at the time of forward movement, the rotation of the wiping roller 9 is repeated at the time of forward movement. In the next advance, the outer peripheral surface of the roller body 13 that comes into contact with the surface to be cleaned is not located at the same location. By this action, the outer peripheral surface of the roller body 13 can be effectively used, and a cleaner wiping and cleaning of the surface to be cleaned can be realized.

Next, the operation of causing the wiping roller 9 to absorb water and using the antibacterial water to retain the water in the roller body 13 will be described.
When the amount of water retained in the roller body 13 of the wiping roller 9 by the preparatory stage for starting wet wiping cleaning or the wet wiping cleaning moves to the surface to be cleaned and becomes a small amount, the wiping roller 9 on one end side in the roller storage chamber 8 is removed. The supporting roller removal door assembly 12 is opened, the wiping roller 9 is removed, and the roller body 13 absorbs water.
In FIG. 6, when tap water is poured from the direction of arrow A with the wiping roller 9 facing the roller inner bearing 14 side upward, the tap water enters the roller shaft 15 through the water flow hole 14a of the roller inner bearing 14, and the arrow The antibacterial eluting body 16 inserted in the roller shaft 15 as shown in FIG. Since the antibacterial eluting body 16 has an antibacterial agent coating 16a on the surface, the antibacterial eluting body 16 that has come into contact with tap water elutes a small amount of the antibacterial agent and mixes with tap water to form the antibacterial water 25. The water flows out of the water discharge hole 15 a opened in the water and is retained in the roller body 13.

The wiping roller 13 in which the antibacterial water is retained is set in the roller storage chamber 8 of the suction port 1 and cleaned by adjusting the amount of retained water to an appropriate level and performing an operation reverse to the removal. The antibacterial water 25 retained by the wiping roller 13 is used for wet wiping cleaning of the surface to be cleaned in a series of cleaning operations.
Therefore, since the water held by the roller body 13 of the wiping roller 9 is water having antibacterial action, it is held by the wiping roller 9 even in an environment where it is difficult to dry after the wet wiping and cleaning without sufficient cleaning. Corrosion of the generated water can be suppressed, and the wiping roller 9 can be kept clean. Furthermore, if the wiping roller 9 is removed and washed with water after completion of the wet wiping cleaning, the effect of preventing corrosion is further enhanced.
Further, in wet wiping, the floor surface is wiped with water having antibacterial action, so that clean wiping can be performed.

FIG. 7 shows a modified example of the antibacterial eluting body 16 inserted inside the roller shaft 15, and a ball-shaped body 24 containing an antibacterial agent having a ball-like dissolution adjustment disposed inside the roller shaft 15. Yes. When tap water is poured from the direction of the arrow A, the tap water enters the roller shaft 15 through the flow hole 14a of the roller inner bearing 14, and the ball-shaped antibacterial disposed inside the roller shaft 15 as indicated by the arrow C. It contacts the agent-containing spherical body 24. The antibacterial agent-containing spherical body 24 in contact with the tap water elutes a trace amount of the antibacterial agent, mixes with the tap water to become the antibacterial water 25, flows out from the water discharge hole 15 a opened in the roller shaft 15, and the roller body 13. To keep water. Even in this case, the same effect as described above can be obtained.
In addition, the antibacterial agent-containing spherical body 24 has a new surface due to surface wear due to mutual collision by using a wiping roller, so that the antibacterial agent is easily eluted every time tap water is put into the roller shaft 15. It becomes.

Embodiment 2. FIG.
Next, Embodiment 2 will be described with reference to FIG. FIG. 8 is a diagram illustrating the water absorption operation of the wiping roller according to the second embodiment. In addition, the same code | symbol is attached | subjected to the structure similar to Embodiment 1, and the description is abbreviate | omitted.
In FIG. 8, the wiping roller 9 placed in a water storage container has an antibacterial agent film 26 mainly composed of silver (Ag) attached to the outer peripheral surface of the roller shaft 15 to form an antibacterial agent layer. By putting the wiping roller 9 in the water in the container, the water passing through the roller body 13 comes into contact with the antibacterial agent coating 26 on the outer peripheral surface of the roller shaft 15. When the film 26 comes into contact with moisture, the silver (Ag) constituting the film becomes positively charged silver ions and comes out of the film 26. At this time, the silver ions coming out of the coating 26 are very small, but are known to exhibit a strong antibacterial effect. The antibacterial effect of silver ions is that it is a well-known technique that microbial cells are negatively charged, and that when positively charged silver ions come into contact with them, the cells are destroyed and the microorganisms die. .

Next, after immersing for a predetermined time, the wiping roller 9 is taken up from the water in the container, and the water retention amount of the antibacterial water 25 of the roller body 13 is appropriately adjusted to set the moisture in the roller storage chamber 8 of the suction port 1. Then, wet wiping cleaning is performed in the same manner as in the first embodiment. In this way, since the water retention of the roller body 13 of the wiping roller 9 is water having antibacterial action, the wiping roller 9 can be kept in an environment that is difficult to dry without sufficient cleaning after the wet wiping cleaning. Corrosion of the retained water can be suppressed, and the wiping roller 9 can be kept clean. Furthermore, if the wiping roller 9 is removed and washed with water after completion of the wet wiping cleaning, the effect of preventing corrosion is further enhanced.
Further, in wet wiping, the floor surface is wiped with water having antibacterial action, so that clean wiping can be performed.
Furthermore, the silver ion which came out from the silver film 26 of the outer peripheral surface of the roller shaft 15 turns the whole water stored in the container into antibacterial water. Since the antibacterial water 25 has an antibacterial action, it can be wet-cleaned on a desk, furniture, or the like by absorbing an appropriate amount of water into a moisture absorber such as a rag.

  The vacuum cleaner provided with the suction tool which has the said effect is obtained by using the vacuum cleaner suction tool of Embodiment 1, 2 for a vacuum cleaner as a suction tool.

  The suction tool with the wiping roller 9 of the present invention can be used for a vacuum cleaner suction tool, and the vacuum cleaner suction tool can be used for a vacuum cleaner.
