Description

  The present invention relates to a suction port body of a vacuum cleaner that moves on a surface to be cleaned such as a floor surface and sucks dust on the surface to be cleaned together with air from a suction port.

  Some suction inlets used in conventional vacuum cleaners include a cleaning body made of a sponge having an impregnation property such as moisture, and cleans a surface to be cleaned such as a dirty floor surface. For example, the suction port body 50 shown in FIG. 7 is cleaned with a rag roll 51 that can be impregnated with moisture by moving back and forth, and is intermittently rotated by the ratchet mechanism 52 to gradually contact the floor surface of the rag roll 51. The position is changing. Further, guide members 53 and 54 such as rubber blades provided before and after the wipe roll 51 are provided with a main suction port 55 and auxiliary suction ports in which dust and filth on the floor surface are disposed forward and backward when moving forward and backward. They are collected near 56 and sucked. (For example, see Patent Document 1)

  However, in this conventional suction port body, when the dust roll 51 is impregnated with moisture or detergent, the floor surface and the like are cleaned, but the guide members 53 and 54 may exist, and the floor surface or the like may be present. There was a problem that water and detergent often remained.

  The problem to be solved is that moisture and detergent used by the cleaning body during cleaning remain on the surface to be cleaned such as the floor surface.

The present invention includes a case body that includes a suction port that faces a surface to be cleaned and that is elongated in a direction perpendicular to the moving direction, and is attached to the case body so as to be rotatable along the suction port. And a rotating body that is rotated by a certain angle range in the opposite direction with each other in reverse, a cleaning side cleaning body that is made of a liquid-absorbing material and is provided on the outer periphery of the rotating body and impregnated with moisture or detergent, A wiping-side cleaning body made of a material having a liquid absorbing property and provided on the outer periphery of the rotating body, and provided on the outer periphery of the rotating body substantially in parallel with the rotating shaft, the cleaning-side cleaning body and the wiping side A boundary part that separates the cleaning body and eliminates movement of moisture or detergent between the cleaning bodies, and one of the cleaning side cleaning body and the wiping side cleaning body in conjunction with the forward and backward movement of the case body And a switching mechanism that selectively contacts the surface to be cleaned. It is characterized in that it has a suction port body of the electric vacuum cleaner.

  The suction port body of the electric vacuum cleaner of the present invention is provided with a plurality of cleaning bodies on the outer periphery of the rotating body, thereby making it possible to use cleaning materials such as moisture and detergent used at the time of cleaning. Is advantageous in that it can be almost eliminated from remaining on the surface to be cleaned such as the floor surface.

  In the suction port body of the electric vacuum cleaner, the above-described effect is realized by providing a plurality of cleaning bodies on the outer periphery of the rotating body and switching and using the cleaning bodies that contact the surface to be cleaned.

  The contents of the present invention will be described with reference to FIGS. FIG. 1 is a cross-sectional view of an embodiment of a suction port body of a vacuum cleaner according to the present invention, and FIG. 2 is a plan view of the suction port body 1 as viewed from below. The suction port body 1 has a generally T-shaped outer shape when viewed from above or below.

Reference numeral 2 denotes a suction port body in which an upper case 3 and a lower case 4 made of a plastic material are joined from above and below and fixed by four screws 8. The suction port body 2 has a predetermined centering on a rotation fulcrum 5. A cylindrical suction pipe 6 that can be rotated in the vertical direction within the angle range is attached in an airtight state . The suction pipe 6 has an air flow path 7 therein, and is detachably connected to the other end of an extension pipe connected to one end of a suction hose connected to a vacuum cleaner body (not shown).

A metal cover 12 is formed on the lower surface of the lower case 4 constituting a part of the suction port body 2 so that an elongated front suction port 10 and a rear suction port 11 are formed in a direction orthogonal to the arrow A in the traveling direction. Is fixed. The cover 12 has an air chamber 13 above the front suction port 10 and the rear suction port 11, and a trumpet-shaped collecting guide portion 14 is provided adjacent to the air chamber 13 so that the inflowing air gathers. Further, the collective guide portion 14 is disposed in the vicinity of the suction pipe 6 so that air can be discharged to the air flow path 7. The upper case 3, the lower case 4, and the cover 12 constitute a case body 9.

  Further, an arcuate portion 15 constituted by a part of the cover 12 is provided in a tunnel shape along the intermediate portion between the front suction port 10 and the rear suction port 11. The arcuate portion 15 has substantially the same length as the entire length of the front suction port 10 and the rear suction port 11, and extends from one side portion of the suction port body 2 to the other side portion.

  On the other hand, inside the arcuate portion 15 is accommodated a cylindrical rotating body 17 that rotates with both ends of the rotating shaft 16 being pivotally supported on both sides of the lower case 4. A plurality of cleaning bodies 20 are provided. Bumpers 21 having elasticity are attached to the front end portion and both side portions of the suction inlet body 2. Further, on both sides of the rear suction port 11 and the arcuate portion 15 in the lower case 4, brush hairs 19 in which a large number of short hair fibers are planted on a substrate are attached. Furthermore, one wheel 23 is attached to the rear lower end of the lower case 4 to facilitate the movement of the suction port body 2.

Next, the structure of the rotating body 17 and the cleaning body 20 and the switching mechanism will be described with reference to FIGS. On the outer periphery of the rotating body 17, one boundary portion 18 is substantially parallel to the rotation center axis of the rotating shaft 16 and is fixed over the entire length from one end to the other end, and is displaced 180 degrees from this one boundary portion. The other boundary 18 is similarly fixed at the symmetrical position . These two boundary portions 18 are formed of plastic or metal, which is a material that does not allow liquid to permeate or permeate, and these are provided by being integrally molded with the rotating body 17 from the beginning with a plastic material. You can also.

  Two cleaning bodies 20, one of which is a cleaning side 20 a and the other of which is a wiping side 20 b, are detachably wound around the outer periphery of the rotating body 17 partitioned by these boundary portions 18. ing. Each of these cleaning bodies 20 is made of the same liquid-absorbing fibrous material that is easily impregnated with liquid, and one of them is impregnated with moisture or a detergent, and the other is not impregnated with anything. The cleaning body 20 may be made of a cotton cloth made of a fibrous material, and the other may be made of a foamable plastic such as a sponge having a higher liquid absorbency, and can be replaced with a new one in a timely manner. FIG. 4 shows a state in which the contact 20c on the wiping side 20b which is one of the cleaning bodies 20 is in contact with the surface to be cleaned 21 such as the floor surface. Since the boundary portion 18 serving as a partition member exists on the outer periphery of the rotating body 17, the one cleaning body 20 (cleaning side 20 a) that is attached adjacent to the other cleaning body 20 (wiping side 20 b). It can prevent moisture and detergent from penetrating and moving directly. Reference numerals 22 denote protrusions fixed on both side surfaces of the rotating body 17 in order to limit the rotating range of the rotating body 17.

  In addition, the two cleaning bodies 20 and the two boundary portions 18 are alternately joined in advance and integrated into a cylindrical shape, and are inserted into one end of the rotating body 17 so as to cover the outer periphery thereof, or may be attached one by one. A single piece of material separated at a place can be attached to the outer periphery of the rotating body 17 so as to be detachable.

  The rotation and switching mechanism of the rotating body 17 and the cleaning body 20 will be described with reference to FIGS. A rotating body 17 having a cleaning body 20 attached to the outer periphery is accommodated inside an arc-shaped portion 15 of the cover 12. Both side walls 23 of the arcuate part 15 are provided with rotation restricting parts 24 each having a through hole or a groove cut out in an arcuate shape within an angle range of 90 degrees corresponding to a quarter rotation. The protrusions 22 protruding from both side surfaces of the rotating body 17 are engaged with the portion 24. Due to these engaged states, the rotating body 17 can be rotated only within a range of 90 degrees. The rotatable range of the rotating body 17 by the rotation restricting unit 24 can be changed by setting the length of the notch to an angle of 120 degrees, for example.

  The cleaning operation of the surface to be cleaned 21 will be described with reference to FIGS. 1, 5, and 6. After inputting the power switch of the cleaner body (not shown) to drive the electric blower, the operator pushes the extension pipe by hand and advances the suction port body 1 in the direction of arrow A. In this advanced state, the rotating body 17 rotates clockwise in FIG. 5 and cannot rotate any more after the projection 22 reaches the end of the rotation restricting portion 24 and is locked. In this state, when the suction port body 1 is further advanced in the A direction, the cleaning side 20a, which is one of the cleaning bodies 20, slides on the surface to be cleaned 21. As a result, the surface to be cleaned 22 is cleaned with moisture or detergent impregnated on the cleaning side 20a.

  Next, when the operator pulls back the hand that pushed out the extension pipe, the suction port body 1 moves backward in the arrow B direction opposite to the arrow A, and the rotating body 17 starts to rotate counterclockwise. Then, when rotated 90 degrees, the state shown in FIG. 6 is reached, and the protrusion 22 is locked to the end of the rotation restricting portion 24 opposite to FIG. 5, and the rotation body 17 is prevented from further rotation. In this state, the suction port body 1 is further moved backward in the B direction, so that the wiping side 20b which is the other cleaning body 20 slides on the surface to be cleaned 21. Thus, moisture or detergent and contaminants adhering to the surface to be cleaned 21 can be wiped off by the wiping side 20b of the other cleaning body 20.

  By repeating the forward and backward operation of the suction port body 1 by such an operator, it is possible to perform suction of dust floating on the surface to be cleaned and cleaning and wiping by the cleaning body 20. At this time, since the front suction port 10 and the rear suction port 11 exist before and after the cleaning body 20, the cleaning work by the cleaning body 20 is performed after the dust on the surface to be cleaned is sucked in both the forward movement and the backward movement. By being performed, the cleaning effect can be improved and the number of replacements and cleaning times of the cleaning body 20 can be reduced. In the cleaning operation, when the cleaning body 20 becomes deficient in moisture and detergent, these are replenished in a timely manner, and when any cleaning body 20 is exhausted, it is replaced or washed. Can withstand long-term use.

  The switching mechanism composed of the protrusion 22 and the rotation restricting portion 24 is different from this embodiment in that the protrusion 22 is turned on both side walls 23 of the arcuate portion 15 of the cover 12 and the both sides of the rotating body 17 are turned. It is also possible to provide a restricting portion 24. In addition, for example, one of the both side walls 23 of the arcuate part 15 and the both side surfaces of the rotating body 17 is provided with protrusions that are spaced apart from each other at a rotation angle of 90 degrees, and the other is provided with these protrusions. The present invention is not limited to the above-described embodiment as long as it is a switching mechanism that restricts forward / reverse rotation of the rotating body 17 to a certain range by providing a single protrusion that can rotate between the two.

  Moreover, in the said Example, although the some cleaning body 20 was attached to the outer periphery of the rotation body 17 used as the column shape, it replaced with this with the comparatively hard material made from plastic which can be impregnated with a water | moisture content or a detergent, If two semi-cylindrical ones are made, and a plastic plate that does not transmit liquid is sandwiched between the two, and joined to form one cylindrical shape, the rotating body 17 and the cleaning member are cleaned. The body 20 can be used with the same material.

  Furthermore, without providing a partition member on the outer periphery of the rotating body 17, by providing a plurality of cleaning bodies 20 by providing a certain spacing portion parallel to the rotation shaft 16 between them, the spacing portion becomes the boundary portion 18. Thus, similarly to the case where a partition member is provided as the boundary portion 18, it is possible to eliminate moisture or detergent permeation between the adjacent cleaning bodies 20. Further, in addition to moisture and detergent, each cleaning body 20 can be separately impregnated with a cleaning material such as an abrasive, a brightener, and a wiping material.

  In addition, the same effect can be achieved even if two rotating bodies are provided apart from each other and the endless cleaning body is bridged between these rotating bodies. In this case, the cleaning body has a shape like a caterpillar which is an endless track, so that the surface area of the cleaning body can be increased and the cleaning effect can be further enhanced.

  Further, the arc-shaped portion 15 provided on the cover 12 that covers the rotating body 17 and the cleaning body 20 is not necessarily provided, but delays the time for the cleaning material such as moisture and detergent impregnated in the cleaning body 20 to evaporate as much as possible. It is necessary for that.

  As a suction port body of an electric vacuum cleaner, it can be applied to an application for effectively cleaning a Western floor such as flooring.
