Description

  The present invention relates to a cleaning device, and more particularly to a cleaning device that rotates a cleaning tool.

  Cleaning of dishes at home is usually done manually using a cleaning tool such as sponge, scrubbing brush or brush, or using an automatic electric dishwasher. In the case of manual cleaning, it is necessary to perform the operation of rubbing the tableware held in one hand with the cleaning tool held in the other hand, which is a heavy labor. In addition, an electric automatic dishwasher requires an electric circuit for rotationally driving a cleaning tool and a structure for isolating the electric circuit from water, which has resulted in complicated and large equipment. . Moreover, since electricity is used, it was not preferable from the viewpoint of energy saving.

  Therefore, a cleaning device that rotates the cleaning tool only with water pressure without using electricity has been proposed. This type of cleaning apparatus is disclosed in, for example, Patent Documents 1 and 2 below.

  The following Patent Document 1 discloses a dishwasher including a rotating piston, a housing, a cylinder chamber, a rotating piston, and a switching valve. The rotating piston includes a cylindrical portion into which the handle portion of the brush is inserted, and a plate-like portion protruding in the radial direction from the outer surface of the cylindrical portion. The rotating piston is attached to the housing so as to be rotatable around the central axis of the cylindrical portion. The rotating piston is configured by partitioning a cylinder chamber formed between the housing and the cylindrical portion with a plate-like portion. The switching valve communicates both sides of the rotating piston alternately with the water supply port and the drainage port. The switching valve is switched by the movement at the end of the rotation of the rotating piston.

  Patent Document 2 listed below includes a case including a through hole through which a faucet is inserted, a shaft receiver fixed in the through hole, a shaft rotatably fixed to the shaft receiver, and an upper end of the shaft. A cleaning device including a plurality of blades and a brush fixed to a lower end of a shaft is disclosed. A plurality of through holes are provided in the shaft receiver. In this cleaning device, water introduced into the through hole passes through the through hole and collides with a plurality of blades. The blades are rotated by the pressure of water, and the shaft and the brush are rotated.

The upper surface and the lower surface of the main body 21 are parallel to a rotation plane PL (FIG. 7) that is a plane on which the plurality of turbine blades 31 rotate.

  The groove 22 is formed on the upper surface of the main body 21. The groove 22 includes a plurality (three in this case) of branch portions 22a, 22b, and 22c. Each of the branch portions 22a, 22b, and 22c extends from the position P1 in different outer diameter directions. Each of the branch portions 22a, 22b, and 22c is formed at equal intervals in the circumferential direction, and is connected to each other at a position P1. A deep bottom portion 23 is formed at the outer diameter side end of each of the branch portions 22a, 22b, and 22c.

The hole 45 is for inserting the gear shaft 55 (FIG. 7).

  In the following description, the guide blade 42 of the guide plate 4A may be referred to as a guide blade 42a, the guide blade 42 of the guide plate 4B may be referred to as a guide blade 42b, and the guide blade 42 of the guide plate 4C may be referred to as a guide blade 42c.

  FIG. 7 is a side view showing the configuration of the turbine 3, the discharge guide portion 4, the lower vessel 7 and the like in the embodiment of the present invention. In FIG. 7, a part of the small-diameter shaft 61 is indicated by a dotted line.

  Referring to FIG. 7, guide plates 4 </ b> A, 4 </ b> B, and 4 </ b> C are fixed to lower container 7 by pillar 93 in a state where they are stacked in this order from top to bottom. Each of the plurality of guide blades 42 has an inclined surface that is inclined with respect to the rotation plane PL extending in the lateral direction in FIG. 7 (extending from the upper right to the lower left in FIG. 7).

  Each of the guide blades 42 a and 42 b (an example of the first guide blade) protrudes upward from the base 41. The guide blades 42 a and the guide blades 42 b protrude alternately along the circumferential direction of the base portion 41. Each of the guide blades 42c (an example of a second guide blade) protrudes downward from the base 41.

  The guide blade 42 protruding upward from the base 41 is constituted by a guide blade 42a of the guide plate 4A and a guide blade 42b of the guide plate 4B. On the other hand, the guide blade 42 protruding downward from the base 41 is constituted by a guide blade 42c of the guide plate 4C. As a result, the number of guide blades 42 projecting upward from the base 41 (16) is twice the number of guide blades 42 projecting downward from the base 41 (eight).

  One guide plate having the same configuration as that of the guide plate 4A is added, and the number of guide blades 42 protruding upward from the base portion 41 is the same as the number of guide blades 42 protruding downward from the base portion 41. It may be.

  The plurality of guide blades 42 are preferably designed in number, spacing, and shape so that the water after colliding with the turbine blades 31 can be efficiently guided downward.

  The discharge guide portion 4 may be integrally formed of resin in addition to the case of being constituted by a plurality of guide plates.

  FIG. 8 is a bottom view showing the configuration of the discharge guide portion 4, the gear 5, the shaft 6, the lower container 7 and the like in the embodiment of the present invention.

  7 and 8, the pillar 93 includes a spacer 93a and a rivet 93b. The spacer 93a has a cylindrical shape. The spacer 93a serves to connect the discharge guide portion 4 and the lower container 7 at a predetermined interval. The rivet 93b is inserted into the spacer 93a. The rivet 93 b fixes the base 41 to the lower container 7.

  The gear 5 is provided in a space between the discharge guide portion 4 and the lower container 7. The gear 5 decelerates the rotation of the turbine 3 and transmits it to the shaft 6. On the other hand, the gear 5 causes the shaft 6 to generate a rotational torque larger than the rotational torque of the turbine 3.

  The gear 5 includes gears 51, 52, 53, and 54 and a gear shaft 55. The shaft 6 includes a small diameter shaft 61 and a large diameter shaft 62 (an example of a lower shaft).

  The gear 51 is fixed to the small diameter shaft 61. The gear 51 and the small diameter shaft 61 are supported by the discharge guide portion 4 and are rotatable with respect to the discharge guide portion 4. The gear 52 is fixed to the large diameter shaft 62. The gear 52 and the large diameter shaft 62 are supported by the lower container 7 and are rotatable with respect to the lower container 7. Each of the gears 53 and 54 is fixed to the gear shaft 55. The gears 53 and 54 and the gear shaft 55 are supported by the discharge guide portion 4 and the lower container 7 and are rotatable with respect to the discharge guide portion 4 and the lower container 7. The gear 51 is in mesh with the gear 53, and the gear 52 is in mesh with the gear 54. The number of teeth of the gear 51 is smaller than the number of teeth of the gear 53, and the number of teeth of the gear 52 is larger than the number of teeth of the gear 54.

  For example, when the gears 51 and 54 have 12 teeth and the gears 52 and 53 have 42 teeth, the gear 5 causes the shaft 6 to rotate about 1 rotation while the turbine 3 rotates 13 times. .

  The lower end of the small diameter shaft 61 is inserted into the large diameter shaft 62 from the upper end of the large diameter shaft 62. The lower end portion of the small diameter shaft 61 is freely rotatable inside the large diameter shaft 62. The large-diameter shaft 62 protrudes outward (downward) from the lower container 7. A male screw 63 is formed at the lower end of the large diameter shaft 62.

  When the gear 51 and the small-diameter shaft 61 are rotated with the rotation of the turbine 3, the gear 53 is rotated by meshing with the gear 51. At this time, the rotational speed of the gear 53 is slower than the rotational speed of the gear 51. The gear 54 and the gear shaft 55 rotate together with the gear 53. When the gear 54 rotates, the gear 52 rotates by meshing with the gear 54. At this time, the rotation speed of the gear 52 is slower than the rotation speed of the gear 54. The large diameter shaft 62 rotates together with the gear 52. As a result, the rotation of the turbine 3 is decelerated and transmitted to the shaft 6.

  In order to employ the shaft 6 having an appropriate length depending on the type of cleaning tool, the shaft 6 may be extendable or detachable from the lower container 7. For example, when the object to be cleaned is tableware such as a cup or a dish, a short shaft 6 may be adopted. When the cleaning device is attached to a shower or hose in a bathroom and the object to be cleaned is a body or the like, a long shaft 6 may be adopted.

  The lower container 7 includes an outer peripheral portion 71 having an annular planar shape, arm portions 72a, 72b, 72c, and 72d extending from the outer peripheral portion 71 toward the inner diameter direction, and arm portions 72a, 72b, 72c, and 72d. The center part 73 connected with each inner diameter side edge part, a plurality of discharge ports 74, and holes 75, 76, 77, and 78 are included. Each of the arm portions 72a, 72b, and 72c is formed at equal intervals in the circumferential direction. The arm portion 72d is formed between the arm portion 72b and the arm portion 72d. A plurality of discharge ports 74 are formed between each of the arm portions 72a, 72b, 72c, and 72d. A plurality of holes 75 for screwing screws 91 are formed in the outer peripheral portion 71. Each of the arms 72a, 72b, and 72c is formed with a hole 76 for inserting the column 93. A hole 77 for inserting the gear shaft 55 is formed in the arm portion 72d. A hole 78 for inserting the shaft 6 is formed in the central portion 73.

  In addition, you may make it eject water in the shape of a shower by comprising the discharge port 74 with a some small hole.

  Next, the operation of the cleaning apparatus will be described.

  FIG. 9 is an exploded perspective view schematically showing the flow of water in the cleaning apparatus 100 according to the embodiment of the present invention.

  Referring to FIG. 9, the water coming out of the faucet is introduced into the inside of the container 9 from the introduction port 14a as indicated by an arrow AR1. The water introduced into the container 9 proceeds downward and falls to the position P1 of the main body 21 that exists just below the portion 14b facing the inside of the container 9 at the inlet 14a. As shown by the arrow AR2, the water that has fallen to the position P1 changes its traveling direction from the downward direction to the three directions of the outer diameter direction, and proceeds in the groove 22. The water that has advanced through the groove 22 is ejected in the outer diameter direction through each of the plurality of ejection ports 25 as indicated by an arrow AR3. The ejected water collides with the adjacent turbine blades 31 and loses the speed in the outer diameter direction. Further, part of the ejected water further collides with the discharge guide portion 4 or the inner wall surface of the upper container 1 and loses the velocity in the outer diameter direction. The water after the collision adheres to the guide blades 42 due to the centrifugal force received from the turbine blades 31 and moves along the guide blades 42 by the action of gravity as indicated by an arrow AR4. The water moved along the guide blade 42 is discharged downward from the discharge port 74. The water discharged from the discharge port 74 is used for cleaning an object to be cleaned (not shown).

  The turbine 3 rotates in the direction indicated by the arrow AR11 by the force received by the water collision. When the turbine 3 rotates, the shaft 6 and the brush BS (FIG. 1) attached to the shaft 6 also rotate in the direction indicated by the arrow AR12. The shaft 6 and the brush BS rotate at a rotational speed that is slower than the rotational speed of the turbine 3 and larger than the rotational torque of the turbine 3 due to the action of the gear 5.

  [Effect of the embodiment]

  According to the present embodiment, the flow rate of water introduced from the introduction port is limited when passing through the groove and the spout provided in the guide portion. Thereby, the pressure of the water which hits a turbine blade | wing can be maintained, reducing the quantity of the water ejected from a jet nozzle. Moreover, since the water spouted from each of the plurality of spouts collides with the turbine blades at different positions, a rotational force can be applied to the turbine at different positions. As a result, the cleaning tool can be rotated with an appropriate rotational torque with a small amount of water, and a large water-saving effect can be obtained.

  Since an electric circuit for rotationally driving the cleaning tool and a configuration for isolating the electric circuit from water are unnecessary, the apparatus can be simplified and miniaturized, and energy saving can be achieved.

  Since it is not necessary to have a cleaning tool and both hands are free, the cleaning effort can be reduced and cleaning becomes easy.

  The water that has collided with the turbine blades is deprived of the propulsive force in the outer diameter direction by the container, and is discharged from the discharge port to the outside of the container by gravity. Thereby, it can utilize for washing | cleaning to-be-washed | cleaned object, without scattering the water after a collision with a turbine blade.

  By providing each of the plurality of recesses on the outer periphery of the guide part and forming each of the plurality of jets there, water can collide with the turbine at an appropriate angle, and the cleaning tool rotates efficiently. Can be made.

  By providing a deep bottom at the outer diameter side end of the branch portion, the water staying in the vicinity of the jet port without flowing into the jet port can be retained in the groove.

  Since the part facing the inside of the container at the inlet and the center of the main body part exist on the rotating shaft of the turbine, the rotation of the turbine can be stabilized.

  When the container includes the upper container and the lower container, the attachment to the faucet is facilitated, and the cleaning device is easily disassembled during cleaning or the like.

  By providing the discharge guide on the outer diameter side of the turbine, the water after colliding with the turbine blade is guided downward by the discharge guide. Thereby, the water after colliding with the turbine blade can be quickly discharged to the outside of the container without inhibiting the rotation of the turbine.

  When the discharge guide includes the upper protrusion and the lower protrusion, the distance for guiding the water after the collision with the turbine blade can be increased, and the discharge guide is easily discharged to the outside of the container.

  Furthermore, the cleaning tool can be rotated at an appropriate speed and torque by providing a plurality of gears that decelerate the rotation of the turbine and transmit it to the shaft.
