  Embodiments of the present invention will be described below.

  The cleaning device in the present embodiment includes a cleaning tank for holding a cleaning liquid, a water wheel type rotating body housed in the cleaning tank, and a motor for rotating the water wheel type rotating body. A plurality of objects to be cleaned can be installed on the outer peripheral portion of the water turbine type rotating body by the holding means. The object to be cleaned may be directly attached to the outer peripheral portion of the water wheel type rotating body, or may be attached in a state of being stored in a storage case for cleaning.

  Further, the cleaning tank includes an inner wall portion, an inner inclined portion, and an inner bottom portion for holding the cleaning liquid, and has a shape in which the bottom portion is squeezed along the outer periphery of the water turbine type rotating body. As a result, it is possible to effectively perform cleaning by reducing the amount of the cleaning liquid used compared to a cleaning tank that does not have the inner inclined portion 2b.

  The water wheel type rotating body with the object to be cleaned can be rotatably installed in the cleaning tank. That is, the protrusion part which protrudes from this side surface is provided in the rotation center of the side surface of a waterwheel type rotary body. A rotating shaft that penetrates the side wall is installed on the side wall of the cleaning tank, and a receiving portion that receives the protrusion of the water turbine type rotating body is installed near the rotating shaft of the inner wall of the cleaning tank. Rotation transmission means for transmitting rotation is provided at the tip of the projection of the water turbine type rotor and the tip of the rotation shaft, and the rotation of the rotation shaft is adjusted by installing the water turbine rotor on the receiving part. Can be communicated to. The rotating shaft is rotated by a motor to rotate the water wheel type rotating body 3.

  The cleaning liquid is supplied in such an amount that the object to be cleaned comes into contact with the cleaning liquid below the rotation center of the water wheel type rotating body. The object to be cleaned attached to the outer peripheral portion of the water wheel type rotating body is rotated together with the water wheel type rotating body by driving the motor, and comes into contact with the cleaning liquid below the rotation center to be cleaned. Due to the rotation of the water wheel type rotating body, relative flowing water is generated in the cleaning liquid around the object to be cleaned. Thereby, even highly viscous deposits such as plaque can be effectively cleaned. Further, by reversing the rotation direction for a predetermined time, the direction in which the cleaning liquid flows with respect to the object to be cleaned is changed, and the cleaning effect is further exhibited. The amount of the cleaning liquid is appropriately determined according to the number of objects to be cleaned, the number of rotations of the water wheel type rotating body, and the like.

  Moreover, let the outer peripheral part of a waterwheel type rotary body be a polygon. By using the polygonal shape, a plurality of storage cases each storing the objects to be cleaned can be easily installed on each side, and a large number of objects to be cleaned can be cleaned at a time.

  In addition, a perforated vane plate is provided radially from the center of rotation at the apex corner of each side of the outer periphery of the water turbine type rotor, and a rubber band or the like as a holding means is passed to the outer periphery between the rubber band and rotor. Hold the storage case containing the items to be cleaned. Thereby, installation of a to-be-cleaned object becomes easy. Further, since the perforated blade plate agitates the cleaning liquid, a complicated water flow is generated with respect to the object to be cleaned, and the cleaning effect can be enhanced.

Further, a strong water can be generated by providing a water conditioner, and this strong oxidation potential water can be used as a cleaning liquid. Since strong oxidation potential water is a strong acid having a pH of 2.7 or less, it has a strong sterilizing effect and cleaning effect. Therefore, it is possible to sterilize viruses and pathogens that adhere to the instrument after medical treatment. Furthermore, the water conditioner generates strongly reducing potential water that is alkaline water together with the generation of strong oxidation potential water. Therefore, it can be used to neutralize strong oxidation potential water as a cleaning liquid after the cleaning is completed.

  Also, an alkaline water tank that stores alkaline water for neutralizing the cleaning liquid, an alkaline water supply valve that controls the supply of alkaline water to the cleaning tank, a drain valve that controls the discharge of drainage from the cleaning tank, and a control A vessel can further be provided. The controller performs generation of cleaning liquid in the water conditioner, rotation of the motor, and control of the valve.

  More specifically, the controller controls the water conditioner to supply a predetermined amount of strong oxidation potential water that comes into contact with the object to be cleaned in the lower part of the cleaning tank to the cleaning tank. Thereafter, the rotation of the motor is controlled to rotate the water turbine type rotating body, and the object to be cleaned installed on the outer periphery thereof is cleaned. Next, the controller stops the rotation of the motor or keeps the rotation while controlling the alkaline water supply valve to supply a predetermined amount of alkaline water to the washing tank.

  In addition, the water conditioner generates strong reduction potential water as well as strong oxidation potential water. Since the strong reduction potential water has alkalinity, it is introduced into an alkaline water tank and used to neutralize the strong oxidation potential water. Thereby, it is not necessary to provide a neutralization tank separately, and a washing | cleaning apparatus can be comprised compactly. Furthermore, the neutralized drainage can be directly subjected to drainage treatment. This eliminates the need for drainage treatment equipment.

  In addition, the cleaning apparatus according to the present embodiment requires a small amount of cleaning liquid. For this reason, when there is no drainage facility nearby, a drainage tank is prepared and the drainage liquid can be stored in the drainage tank. Furthermore, strong oxidation potential water is used as the cleaning liquid, and the strong reduction potential water produced when the strong cleaning potential water is used as the neutralizing water can be used as the cleaning liquid after use. It can be used effectively and the amount of drainage can be reduced.

  Hereinafter, the present embodiment will be described in detail with reference to the drawings.

  FIG. 1 is a schematic cross-sectional view showing the cleaning device 1. The square-shaped cleaning tank 2 accommodates a hexagonal water wheel type rotor 3 and holds a cleaning liquid 6 at the bottom. The lower part of the cleaning tank 2 has an inner inclined part 2b between the inner wall part 2a and the inner bottom part 2c so as to follow the outer periphery of the water turbine type rotating body 3. It is because the usage-amount of the washing | cleaning liquid 6 can be decreased by forming the bottom part of the washing tank 2 so that the outer periphery of the waterwheel type rotary body 3 may be followed. The inner inclined portion 2b of the cleaning tank 2 has a U-shaped or semicircular bowl shape in the lower part of the cleaning tank 2 in addition to an inclined surface along the outer periphery of the water turbine type rotating body 3. Including. A lid 12 is installed on the upper part of the cleaning tank 2 to prevent the cleaning liquid 6 from splashing outside.

Further, the object to be cleaned 4 can be directly attached to the outer peripheral portion of the water turbine type by holding means such as a clip without storing it in the storage case 5. Further, without using the rubber band 26, a fixing device that is a holding means for fixing the storage case 5 may be provided and fixed to the outer peripheral portion of the water turbine type rotating body 3. In this case, it is possible to remove the blade 18 installed on the outer peripheral portion of the water wheel type rotor 3.

  The cleaning liquid 6 held at the bottom of the cleaning tank 2 is supplied to such an extent that the cleaning liquid 6 comes into contact with the object to be cleaned 4 below the rotation center of the water wheel type rotor 3. The amount of the cleaning liquid 6 is appropriately set according to the number of the objects to be cleaned 4 and the rotation speed of the water wheel type rotating body 3. The reason why the cleaning liquid 6 is supplied to the extent that the water wheel type rotor 3 is buried is that the load on the motor 10 increases, the amount of alkaline water for neutralizing the cleaning liquid later increases, and the waste liquid after neutralization treatment. The amount also increases. Therefore, it becomes disadvantageous when performing a simple waste water treatment. Therefore, it is preferable that the amount of the cleaning liquid 6 be less than or equal to the rotation center of the water wheel type rotor 3.

  The water turbine type rotating body 3 has a shaft 8 integrally formed with the water wheel type rotating body 3 at the center of rotation, and an end portion of the shaft 8 is provided with a protruding portion 21 protruding from a side surface of the water wheel type rotating body 3.

The belt 11 is preferably a toothed belt. This is to prevent slippage between the pulley 9 and the belt 11 when the rotational torque increases due to the resistance between the water wheel type rotor 3 and the cleaning liquid 6. In the present embodiment, the rotation of the motor 10 is transmitted to the rotating shaft 23 by the belt 11 and the pulley 9, but this is attached to the side wall of the cleaning tank 2, and the rotating shaft 23 is connected to the motor. The rotary shaft 23 may be directly connected to the rotary shaft 10 and the rotary shaft 23 may be directly rotated by the motor 10, or may be rotated via a gear or the like.

  Six holes 16 are formed in the side plate 17. This is to reduce the weight of the water turbine type rotating body 3 and to allow the cleaning liquid 6 to easily flow into the bottom of the cleaning tank 2 from the hole 16 when the water wheel type rotating body 3 rotates.

  Each vane 18 is formed with a window 19 at the center thereof. Since the cleaning liquid 6 flows out to the object to be cleaned 4 through this window portion 19 and the cleaning liquid is agitated, a complicated water flow is generated with respect to the object to be cleaned 4 and the cleaning effect can be further enhanced.

  A groove 20 is formed in the outer periphery of the blade plate 18, and a rubber band 26 is attached to the groove 20 so that the storage case 5 for storing the article 4 to be cleaned can be fixed to the side plate 17. The shaft 8 has a protruding portion 21 protruding from the side plate 17, and by mounting the protruding portion 21 on the U-shaped portion 25 of the receiving portion 7, the water wheel type rotating body 3 can be detachably stored in the cleaning tank 2. it can.

  A convex portion 24 is provided at the end of the rotating shaft 23 provided on one side wall of the cleaning tank 2, and the convex portion 24 and the concave portion 22 provided in the protruding portion 21 of the water turbine type rotating body 3 are joined to form a water Rotational power can be transmitted to the vehicle-type rotating body 3. Therefore, the convex part 24 of this rotating shaft 23 and the projection part 21 of the waterwheel type rotary body 3 function as a rotation transmission means.

  In FIG. 2, the water wheel type rotating body 3 is a hexagon, but is not limited to a hexagon, and may be a pentagon, an octagon, or more polygons and a circle. In addition to storing the object to be cleaned 4 in the storage case 5 and mounting and cleaning the storage case 5 on the outer periphery of the water wheel type rotating body 3, do not store the object 4 to be cleaned in the storage case 5. The object 4 to be cleaned may be directly attached to the outer peripheral portion. Furthermore, in the above example, the example in which the blade plate 18 having the window portion 19 is installed has been described.
