Description

  The present invention relates to a suction tool and a vacuum cleaner.

  The vacuum cleaner includes a suction tool for sucking in garbage. For example, when the floor is cleaned with an electric vacuum cleaner, the speed of the airflow for sucking up dust increases as the clearance between the suction tool and the floor decreases. However, if the gap between the suction tool and the floor is small, it will not be possible to suck up large garbage falling on the floor.

  For example, Patent Document 1 describes a vacuum cleaner. In the vacuum cleaner described in Patent Document 1, notches are formed at regular intervals on the front surface of the suction tool.

  FIG. 3 is a perspective view showing an example of the suction tool 2 according to Embodiment 1 of the present invention. FIG. 4 is a plan view of the suction tool 2 shown in FIG. FIG. 5 is a bottom view of the suction tool 2 shown in FIG. FIG. 6 is a side view of the suction tool 2 shown in FIG. FIG. 7 is a cross-sectional view taken along line AA of the suction tool 2 shown in FIG. With respect to the suction tool 2, as shown in FIG. The direction perpendicular to the vertical direction and the front-rear direction is the width direction of the suction tool 2.

  The suction tool 2 includes, for example, a case 13, a connecting pipe 14, a rotating brush 15, and a rotating body 16 in addition to the motor 12.

  As shown in FIG. 4, the case 13 has a rectangular shape as viewed from above. For example, the width W of the case 13 is preferably 10 cm or more and 30 cm or less in consideration of operability. In the example shown in the present embodiment, the width W of the case 13 matches the width of the suction tool 2. The suction port 2 a is formed in the case 13. The suction port 2a opens downward and forward. The case 13 includes, for example, a lower case 17, a bearing portion 18, a bearing portion 19, a storage portion 20, an upper case 21 and a cover 22.

  The lower case 17 has a rectangular shape as viewed from above. A bearing 18 is provided at one end of the lower case 17. The bearing portion 18 projects forward from the lower case 17. A bearing portion 19 is provided at the other end of the lower case 17. The bearing portion 19 projects forward from the lower case 17 in the same manner as the bearing portion 18. The lower case 17, the bearing portion 18 and the bearing portion 19 form a lower surface 13 a of the case 13.

  The storage unit 20 forms a space for storing the rotating body 16. In the example shown in the present embodiment, a space for storing the rotating body 16 is formed below the storage unit 20. 3 to 7 show examples in which the storage unit 20 has a curved plate shape. The storage unit 20 is curved in the front-rear direction of the suction tool 2. The storage unit 20 is not curved in the width direction of the suction tool 2. The storage unit 20 is provided in the lower case 17 so as to protrude from the front surface of the lower case 17. The storage unit 20 is arranged along the width direction of the suction port 2a. The storage unit 20 goes downward as it goes forward. As for the accommodating part 20, the front-end | tip 20a is arrange | positioned lowest. The tip 20 a is disposed above the lower surface 13 a of the case 13. The storage unit 20 may be formed integrally with the lower case 17.

  In the example shown in the present embodiment, the suction port 2 a is formed by the lower case 17, the bearing portion 18, the bearing portion 19, and the storage portion 20. An opening surrounded by the lower case 17, the bearing portion 18, the bearing portion 19, and the storage portion 20 is the suction port 2a.

  The upper case 21 is disposed so as to cover the lower case 17, the bearing portion 18, and the bearing portion 19 from above. The upper case 21 is provided on the lower case 17, the bearing portion 18, and the bearing portion 19. The cover 22 is provided on the upper case 21 so as to cover a part of the upper case 21.

  The connecting pipe 14 is a cylindrical member for connecting the suction tool 2 to the extension pipe 3. The connecting pipe 14 is provided in the case 13. For example, the connecting pipe 14 is provided in the center portion of the case 13 in the width direction. The angle of the connecting pipe 14 with respect to the case 13 is variable within a certain range. The space formed inside the connecting pipe 14 leads to the space formed inside the case 13. Garbage sucked into the suction tool 2 from the suction port 2 a is sent to the extension pipe 3 through a space formed inside the case 13 and a space formed inside the connecting pipe 14.

  The rotating brush 15 is rotatably supported by the case 13. For example, one end of the rotating brush 15 is supported by being sandwiched between the bearing 18 and the upper case 21 from above and below. The other end of the rotating brush 15 is supported by being sandwiched between the bearing 19 and the upper case 21 from above and below. At least a part of the rotating brush 15 is disposed immediately above the suction port 2a. The connecting tube 14 is connected to the case 13 behind the rotating brush 15.

  The rotating brush 15 includes, for example, a shaft member 23, a cleaning member 24, and a scraping member 25.

  The shaft member 23 has, for example, a cylindrical member. The shaft member 23 is supported by the case 13 on the shaft extending from the cylindrical member to both sides. The shaft member 23 is disposed such that the axial direction is along the width direction of the suction port 2a.

  The cleaning member 24 is a member for scooping up dust on the surface to be cleaned and taking the dust into the case 13. The surface to be cleaned is, for example, a floor, a tatami mat, and a carpet. The cleaning member 24 is provided on the outer peripheral surface of the shaft member 23 so as to cover the columnar member, for example. For example, the cleaning members 24 are arranged on the outer peripheral surface of the shaft member 23 at equal intervals. The cleaning member 24 may be disposed along the axial direction of the shaft member 23. For example, the cleaning member 24 may be arranged in a spiral shape. As the cleaning member 24, for example, fibrous brush hair is used. A blade-shaped member may be used as the cleaning member 24. Other members may be used as the cleaning member 24. A plurality of members may be used as the cleaning member 24.

  The cleaning member 24 is disposed such that a portion extending directly below the shaft member 23 passes through the suction port 2a. That is, the cleaning member 24 protrudes downward from the lower surface 13 a of the case 13. The lower end of the cleaning member 24 may be disposed above the lower surface 13 a of the case 13. In this case, if the surface to be cleaned is a floor or the like, the cleaning member 24 does not contact the surface to be cleaned.

  The scraping member 25 is a member for scraping off dust adhering to the rotating body 16. The scraping member 25 is provided on the outer peripheral surface of the shaft member 23 so as to protrude from the outer peripheral surface of the shaft member 23. Similarly to the cleaning member 24, the scraping member 25 may be provided on the shaft member 23 so as to cover the columnar member. For example, the scraping members 25 are arranged at equal intervals on the outer peripheral surface of the shaft member 23. The scraping member 25 may be disposed along the axial direction of the shaft member 23. For example, the scraping member 25 may be arranged in a spiral shape. As the scraping member 25, for example, fibrous brush hair is used. A blade-like member may be used as the scraping member 25. Other members may be used as the scraping member 25. A plurality of members may be used as the scraping member 25. The scraping member 25 is preferably harder than the cleaning member 24.

  The scraping member 25 contacts the rotating body 16. The cleaning member 24 may not contact the rotating body 16. FIG. 7 shows an example in which the amount of protrusion of the scraping member 25 from the outer peripheral surface of the shaft member 23 is larger than the amount of protrusion of the cleaning member 24.

  The rotating body 16 is rotatably supported by the case 13. For example, one end portion of the rotating body 16 is supported by being sandwiched between the bearing portion 18 and the upper case 21 from above and below. The other end of the rotator 16 is supported by being sandwiched between the bearing 19 and the upper case 21 from above and below. At least a part of the rotating body 16 is disposed immediately above the suction port 2a. A part of the suction port 2 a is arranged behind the rotating body 16. The rotating brush 15 is disposed behind the rotating body 16. The connecting pipe 14 is provided in the case 13 behind the rotating body 16.

  The rotating body 16 includes, for example, a shaft member 26 and an elastic member 27.

  The shaft member 26 has, for example, a cylindrical member. The shaft member 26 is supported by the case 13 on the shaft extending from the cylindrical member to both sides. The shaft member 26 is disposed in parallel to the shaft member 23 of the rotary brush 15, for example. The shaft member 26 is disposed such that the axial direction is along the width direction of the suction port 2a.

  In the example shown in the present embodiment, the rotation shaft of the shaft member 26 is disposed outside the box-shaped member formed by the lower case 17, the bearing portion 18, the bearing portion 19, and the upper case 21. The storage unit 20 is disposed above the rotating body 16. FIG. 7 shows an example in which the surface of the storage portion 20 that faces the rotating body 16 is curved so as to be along the outer peripheral surface of the shaft member 26.

  The elastic member 27 is provided on the outer peripheral surface of the shaft member 26 so as to cover the columnar member of the shaft member 26, for example. For example, the elastic members 27 are arranged at equal intervals on the outer peripheral surface of the shaft member 26. As the elastic member 27, for example, flocking made of an elastic material is used. As the elastic member 27, a soft material that is relatively easily deformed, such as elastomer, vinyl chloride, and silicon, may be used. The elastic member 27 is preferably softer than the cleaning member 24.

  The rotating body 16 is arranged so as to block a part of the suction port 2a. For example, the lower end of the elastic member 27 is disposed below the upper end of the suction port 2a. In the example shown in FIGS. 3 to 7, the lower end of the elastic member 27 is disposed below the tip 20 a of the storage unit 20. The elastic member 27 may not protrude downward from the lower surface 13 a of the case 13. The elastic member 27 may protrude downward from the lower surface 13 a of the case 13.

  The elastic member 27 contacts the case 13 along the axial direction of the shaft member 26. In the example shown in the present embodiment, the elastic member 27 comes into contact with the storage unit 20 disposed above from below. A symbol B in FIG. 7 indicates a position where the elastic member 27 contacts the storage unit 20. For example, the elastic member 27 contacts the lower surface of the storage unit 20 in a straight line in the axial direction of the shaft member 26. The scraping member 25 of the rotating brush 15 comes into contact with the elastic member 27 behind the position where the elastic member 27 comes into contact with the storage unit 20. The scraping member 25 does not contact the shaft member 26.

  The motor 12 generates a driving force for rotating the rotary brush 15. The rotating brush 15 is rotationally driven by the motor 12. The suction tool 2 may include a belt or the like for transmitting the rotation of the rotating brush 15 to the rotating body 16. In such a case, the rotating body 16 is also rotationally driven by the motor 12.

  If it is an example shown in this Embodiment, in the vacuum cleaner 1, high suction performance can be ensured. In other words, the elastic member 27 contacts the case 13 along the axial direction of the shaft member 26. The lower end of the elastic member 27 is disposed below the upper end of the suction port 2a. For this reason, it can prevent that the speed of the air current for inhaling garbage falls.

  Since the elastic member 27 is deformed, even large dust can pass under the rotating body 16. Further, the dust can be guided to the inside of the case 13 by the rotation of the rotating body 16. For this reason, in the example shown in the present embodiment, it is possible to suck in large garbage.

  FIG. 8 is a view showing another example of the suction tool 2 according to Embodiment 1 of the present invention. FIG. 8 is a cross-sectional view corresponding to FIG. In the suction tool 2 shown in FIG. 8, the rotary brush 15 does not include the scraping member 25. In the suction tool 2 shown in FIG. 8, the storage unit 20 includes a base body 28 and a seal member 29. Other features of the suction tool 2 shown in FIG. 8 are the same as those of the suction tool 2 shown in FIGS. In the example shown in FIG. 8, the rotating brush 15 may include a scraping member 25.

  FIG. 8 shows an example in which the base 28 is flat. The base 28 is provided on the lower case 17 so as to protrude from the front surface of the lower case 17. The base body 28 moves downward as it goes forward. The base 28 may be formed integrally with the lower case 17.

  The seal member 29 is provided on the lower surface of the base body 28. For example, the seal member 29 is disposed so as to cover the lower surface of the base 28. As the seal member 29, for example, flocking made of an elastic material is used. A velor made of an elastic material may be used as the seal member 29. As the seal member 29, a soft material that is relatively easily deformed, such as elastomer, vinyl chloride, and silicon, may be used. In the example illustrated in FIG. 8, the elastic member 27 contacts the seal member 29 in a straight line in the axial direction of the shaft member 26. In the example shown in FIG. 8, the generation of airflow passing between the rotating body 16 and the storage unit 20 can be further suppressed.

  FIG. 9 is a view showing another example of the suction tool 2 according to Embodiment 1 of the present invention. FIG. 9 is a cross-sectional view corresponding to FIG. In the suction tool 2 shown in FIG. 9, the rotary brush 15 does not include the scraping member 25. In the suction tool 2 shown in FIG. 9, the storage unit 20 includes a base 28 and a seal member 29. The suction tool 2 shown in FIG. 9 further includes a scraper 30. Other features of the suction tool 2 shown in FIG. 9 are the same as those of the suction tool 2 shown in FIGS.

  FIG. 9 shows an example in which the seal member 29 is provided at the tip of the base 28. The feature of the seal member 29 is the same as the feature of the seal member shown in FIG. For example, the elastic member 27 contacts the seal member 29 in a straight line in the axial direction of the shaft member 26.

  The scraper 30 is a member for scraping off dust adhering to the rotating body 16. The scraper 30 is provided in the case 13. FIG. 9 shows an example in which the scraper 30 is provided on the base 28. The scraper 30 is disposed so as to protrude into a space formed inside the case 13. The scraper 30 contacts the rotating body 16. For example, the scraper 30 contacts the elastic member 27 behind the position where the elastic member 27 contacts the storage unit 20. The scraper 30 does not contact the shaft member 26. By providing the scraper 30, the rotating body 16 can be kept clean as in the case where the rotating brush 15 includes the scraping member 25.

  In the example shown in the present embodiment, the suction tool 2 includes a rotating brush 15. This is an example. Even if the suction tool 2 does not include the rotating brush 15, the above effect can be realized. When the suction tool 2 does not include the rotating brush 15, the motor 12 may be used only for rotating the rotating body 16.

  In the example shown in the present embodiment, the rotating body 16 is driven by the motor 12. The motor 12 may be provided only for rotating the rotary brush 15.

Embodiment 2. FIG.
FIG. 10 is a perspective view showing an example of the suction tool 2 according to Embodiment 1 of the present invention. The suction tool 2 shown in FIG. 10 is also detachable from one end of the extension pipe 3. In this embodiment, differences from the example disclosed in Embodiment 1 will be described in detail. For features not described in the present embodiment, any of the features disclosed in the first embodiment may be employed.

  FIG. 11 is a plan view of the suction tool 2 shown in FIG. FIG. 12 is a bottom view of the suction tool 2 shown in FIG. FIG. 13 is a side view of the suction tool 2 shown in FIG. 14 is a cross-sectional view of the suction tool 2 shown in FIG.

  The suction tool 2 includes, for example, a motor 12, a case 13, a connecting pipe 14, a rotating brush 15, and a rotating body 16. The suction tool 2 may include a scraper 30. A suction port 2 a that opens downward and forward is formed in the case 13. The case 13 includes, for example, a lower case 17, a bearing portion 18, a bearing portion 19, a storage portion 20, an upper case 21 and a cover 22. The storage unit 20 includes a base 31 and a buffer 32.

  10 to 14 show examples in which the storage portion 20 has a curved plate shape as a whole. For example, the storage unit 20 is curved so that the surface facing the rotating body 16 is along the outer peripheral surface of the shaft member 26. The base 31 is provided on the lower case 17 so as to protrude from the front surface of the lower case 17. The base 31 is disposed along the width direction of the suction port 2a. The base 31 is disposed above the rotating body 16.

  The buffer 32 is provided on the base 31. The buffer 32 is provided at the tip of the base 31 so as to protrude forward from the base 31, for example. The buffer 32 is arranged along the width direction of the suction port 2a. The buffer 32 is softer than the base 31. As the buffer 32, for example, flocking made of an elastic material is used. As the buffer 32, a soft material that is relatively easily deformed, such as elastomer, vinyl chloride, and silicon, may be used.

  The elastic member 27 of the rotating body 16 contacts the case 13 along the axial direction of the shaft member 26. In the example shown in the present embodiment, the elastic member 27 comes into contact with the storage unit 20 disposed above from below. The elastic member 27 may contact the lower surface of the base 31 in a straight line in the axial direction of the shaft member 26.
