Further, the output unit of the controller 44 c is connected to the brush motor 27 via the power supply line 53. Thereby, the electric power supply means 7 which supplies electric power with respect to the washing | cleaning unit U1 is comprised.

  Next, the usage method and operation | movement of the washing | cleaning apparatus 1 which concern on this embodiment are demonstrated based on FIGS. 9-11, referring FIGS.

When the cleaning apparatus 1 is used, the cleaning liquid tank 42 contains a predetermined cleaning liquid L and the cleaning liquid recovery tank 45 is emptied. A battery 56 that has been charged is mounted. And the washing | cleaning apparatus 1 is taken to the arbitrary washing | cleaning places in a cowshed. Since the second cleaning brush portion 3b is biased upward by the springs 38, the second cleaning brush portion 3b in the unmounted cleaning unit U1 is at the highest position shown in FIG. On the other hand, the cleaning includes preliminary cleaning and main cleaning. FIG. 9 shows a timing chart of a sequence control pattern used when performing preliminary cleaning and main cleaning.

  First, pre-cleaning is performed. The preliminary cleaning is performed for the purpose of making it easier to remove dirt in the main cleaning by wetting each teat Mm... With the cleaning liquid L before performing the main cleaning. First, the cleaning unit U1 is attached to an arbitrary teat Mm, that is, the teat Mm is inserted into the housing part 2 through the insertion hole 8i of the cleaning member 8 in the insertion port 2i. Then, the operation switch 25 is pressed to turn it ON. In this case, the switch is turned on only while the operation switch 25 is pressed, and the cleaning liquid pump 43, the upper injection valve 54u, the lower injection valve 54d, the brush motor 27, and the suction fan 47 correspond to the ON of the operation switch 25. Each is turned ON.

  When the cleaning liquid pump 43, the upper injection unit valve 54u, and the lower injection unit valve 54d are turned on, the cleaning liquid L in the cleaning liquid tank 42 is transferred to the upper injection unit 5u and the lower injection unit 5d via the opened liquid supply tubes 51u and 51d. Supplied. Then, as shown in FIG. 10, the cleaning liquid L is injected above the cleaning member 8 from the upper injection holes 23 u... And injected below the cleaning member 8 from the lower injection holes 23 d. In addition, power is supplied to the brush motor 27 via the battery 56, the controller 44c, and the power supply line 53, and the brush motor 27 repeats forward rotation and reverse rotation alternately (in the direction of arrow Fpn in FIG. 10). In FIG. 9, Ts indicates a normal rotation (or reverse rotation) time, and Ti indicates a slight stop time of the brush motor 27 between the normal rotation and the reverse rotation. The forward / reverse times can be set to about 0.4 to 0.8 [seconds]. By the rotation of the brush motor 27, the first cleaning brush portion 3a, the second cleaning brush portion 3b, and the cleaning member 8 are rotated together, and the nipple Mm is preliminarily cleaned. Further, since the inside of the drainage tube 52 is sucked when the suction fan 47 is turned on, the used cleaning liquid L inside the housing portion 2 is collected in the cleaning liquid collection tank 45 in the main unit U2 via the drainage tube 52. (Reserved).

  On the other hand, the operator releases (OFF) pressing of the operation switch 25 at an appropriate time. In FIG. 9, Ta indicates the ON time of the operation switch 25. The preliminary cleaning is intended to wet the teat Mm with the cleaning liquid L, and therefore, the time Ta is only a few seconds. As for the time Ta, a maximum time Tam is set, and when the maximum time Tam is exceeded, a control pattern in the main cleaning described later is obtained. When the operation switch 25 is turned OFF, the cleaning liquid pump 43, the upper injection valve 54u, the lower injection valve 54d, and the brush motor 27 are also turned OFF. However, even if the operation switch 25 is turned off, the suction fan 47 is turned off after a time Tb, for example, about several seconds. Thus, the preliminary cleaning of one nipple Mm is completed. The same preliminary cleaning is sequentially performed on the other three teats Mm.

  When the preliminary cleaning is completed, the main cleaning is then performed. Although the basic operation in the main cleaning is the same as that in the preliminary cleaning, the operator can arbitrarily change the time for pressing the operation switch 25 (ON time) in consideration of the degree of contamination of the teat Mm. First, the cleaning unit U1 is attached to an arbitrary teat Mm, that is, the teat Mm is inserted into the housing portion 2 through the insertion hole 8i of the cleaning member 8 in the insertion port 2i (see FIG. 10). Then, the operation switch 25 is pressed to turn it ON. In FIG. 9, Td indicates the ON time of the operation switch 25.

  When the operation switch 25 is turned on, the cleaning liquid pump 43, the upper injection valve 54u, the lower injection valve 54d, the brush motor 27, and the suction fan 47 are turned on. Therefore, as in the case of the preliminary cleaning, the cleaning liquid L in the cleaning liquid tank 42 is supplied to the upper injection unit 5u and the lower injection unit 5d through the opened liquid supply tubes 51u and 51d. Then, as shown in FIG. 10, the cleaning liquid L is injected above the cleaning member 8 from the upper injection holes 23 u... And injected below the cleaning member 8 from the lower injection holes 23 d. Further, the brush motor 27 repeats forward rotation and reverse rotation alternately (in the direction of arrow Fpn in FIG. 10). By the rotation of the brush motor 27, the first cleaning brush portion 3a, the second cleaning brush portion 3b, and the cleaning member 8 are rotated together, and main cleaning of the teat Mm is performed.

  In this case, the first cleaning brush portion 3a cleans the peripheral surface portion Mf of the nipple Mm with the brush-like cleaning brush 3ax. In addition, the second cleaning brush portion 3b cleans the boundary surface Msr portion at the tip Ms of the nipple Mm with the boundary surface cleaning brush 3bx using the sheet piece portions 13 ... and also has the cylindrical protrusion 10 ... The tip surface cleaning brush 11 used is used to clean the tip surface Mss portion of the tip Ms of the nipple Mm. At this time, since the boundary curved surface cleaning brush 3bx uses the sheet piece portion 13 ..., there is an advantage that dust does not easily adhere, and the tip surface cleaning brush 11 uses the cylindrical protrusion 10 ... Dirt on the teat Mm can be easily scraped off by the edge portion 10e. Further, by the rotation of the cleaning member 8, the root portion Mmb in the teat Mm is cleaned by the cleaning unit 8 w (fin-shaped portion 8 wf...), And this cleaning is performed by injection from the upper injection unit 5 u disposed above the cleaning member 8. The cleaning liquid L to be used is used. At this time, since the disc-shaped cleaning member 8 is used, the dust is partly or entirely removed by the cleaning member 8 and quickly washed away by the cleaning liquid L before being scraped off by the brush of the brush mechanism unit 3. . That is, the cleaning liquid L used for cleaning the root portion Mmb enters the inside through the gap between the insertion hole 8i of the cleaning member 8 and the nipple Mm by the cleaning water pressure and the suction pressure, travels through the peripheral surface portion Mf of the nipple Mm, and the tip Ms. Flushed to the side.

  Thus, in the cleaning apparatus 1 according to the present embodiment, effective and sufficient cleaning can be performed on the root portion Mmb in the teat Mm. Therefore, adherence of dirt to the teat cup liner during milking can be avoided, contributing to ensuring hygienic production of milk, preventing milk quality deterioration and mastitis, etc., and eliminating residual dirt, so confirmation after washing Additional cleaning by work or manual work is unnecessary or reduced, so that workability and work efficiency can be improved. Even if dust (rice straw, sawdust, rice husk, feces, etc.) is attached to the nipple Mm, the dust is removed by the cleaning member 8 before being scraped off by the brush of the brush mechanism 3. At the same time, the cleaning liquid L quickly causes the dust to adhere to the brush in the brush mechanism 3. Accordingly, it is possible to eliminate or reduce the reduction of the cleaning ability and the frequent removal work of dust attached to the brush, and to efficiently wipe with a smaller amount of the cleaning liquid L. Furthermore, since the cleaning member 8 having the cleaning portion 8w on the upper surface rotates to clean the root part Mmb in the object M to be cleaned, there is no need to press the cleaning unit U1 against the root part Mmb with an excessive force. In addition, it is possible to avoid the adverse effect of placing an unnecessary burden on the root part Mmb side and to avoid the adverse effect of unnecessarily increasing the cleaning time. In addition, since the injection unit 5 including the upper injection unit 5u disposed above the cleaning member 8 and the lower injection unit 5d disposed below the cleaning member 8 is provided, the root region Mmb from the tip portion Ms of the teat Mm with a small amount of cleaning liquid L is provided. Can be cleaned efficiently.

  On the other hand, since the inside of the drainage tube 52 is sucked by the suction fan 47, the used cleaning liquid L inside the housing portion 2 is recovered (stored) in the cleaning liquid recovery tank 45 in the main unit U2 via the drainage tube 52. ) Therefore, it is possible to avoid a problem that the dirty cleaning liquid L after use is unnecessarily discharged to the outside.

  Then, the operator releases (OFF) pressing of the operation switch 25 at an appropriate time. In FIG. 9, Td indicates the ON time of the operation switch 25. Since the main cleaning is regular cleaning, the time Td is set longer than the time Ta during the preliminary cleaning. In the example, the time Td is about twice the time Ta. Since the time Td exceeds the maximum time Tam, when the maximum time Tam elapses, the upper injection valve 54u is automatically turned OFF, and the injection of the cleaning liquid L from the upper injection unit 5u is stopped. Therefore, after the maximum time Tam has elapsed, the substantial cleaning of the root portion Mmb of the nipple Mm is completed, and the cleaning member 8 starts draining and drying by the rotating fin-shaped portion 8wf.

  When the operation switch 25 is turned OFF, the rotation of the brush motor 47 rotates only in the forward rotation direction (in the direction of arrow Fp in FIG. 11) as shown in FIG. Further, the cleaning liquid pump 43 and the lower injection section valve 54d continue to be turned on as they are, and the cleaning liquid pump 43, the lower injection section valve 54d and the brush motor 47 are turned off after elapse of a preset Te time (for example, about several seconds). become. Therefore, after the operation switch 25 is turned OFF, the cleaning unit U1 is detached from the teat Mm within this Te time. In this case, since the cleaning member 8 functions as a blower fan by the rotating fin-like portions 8wf ... within the Te time, the cleaning unit U1 is quickly removed from the teat Mm within the Te time. Smooth draining and drying. In particular, in addition to such a fan function, even when the cleaning liquid L is continuously sprayed from the lower spraying portion 5d during the separation, a portion where the diameter of the peripheral surface portion Mf of the teat Mm is larger than the insertion hole 8i of the cleaning member 8. The drainage is performed by the insertion hole 8i, and the portion where the diameter of the peripheral surface portion Mf of the nipple Mm is smaller than the insertion hole 8i of the cleaning member 8 is a high-speed approach of air from the gap between the insertion hole 8i and the peripheral surface portion Mf. Rapid liquid draining and drying can be performed by rotating the brush mechanism unit 3 only in the forward rotation direction. FIG. 11 shows a state at the time of separation. If the Tf time (for example, about several seconds) further elapses after the Te time elapses, the suction fan 47 is automatically turned off. Thus, the main cleaning of one nipple Mm is completed. The same main cleaning is sequentially performed on the other three teats Mm.
