The rinsing unit 3 can remove relatively small debris, and can efficiently purify by utilizing the respective characteristics of beating and cleaning with a liquid. Regarding the refuse that is firmly attached to the rug, first, the refuse that is firmly adhered to the rug by beating in the beating unit 1 is lifted off the rug, and then the refuse is easily floated and removed in the washing unit 2 and the rinsing unit 3. Garbage can be removed, and efficient purification can be achieved by taking advantage of the characteristics of beating and washing with liquid.

Further, in the present rug cleaning machine, since the beating is performed by the hitting member 11 and the spring 12 which are supported by the shaft, a low-speed rotation motion (the rotation motion of the lifting member 15) which can be relatively easily realized by the electric motor. Thus, it can be converted into a high-speed intermittent beating motion by the beating member 11. Therefore, while realizing a movement speed and force sufficient for removing dust, a large-output motor is not required, and the apparatus can be downsized.

Further, since the cleaning brush roller 21 and the rinsing brush roller 31 rotate at a different peripheral speed from the transport roller 51, the rug to be transported can be effectively cleaned and rinsed. Further, since the squeezing roller 41 performs squeezing in the rinsing unit 3, rugs can be squeezed while maintaining a constant transport speed.

Since the beating and washing are performed while the rug is conveyed at a constant speed by the conveying roller 51, simple control of detecting the rug by a limit switch and activating and stopping the washing valve 23 and the rinsing valve 33 with a certain time delay. Thus, washing and rinsing can be performed only for a necessary time, and resources of the washing liquid and washing water can be saved. Also,
Since the control is simple, the cost of the apparatus can be reduced, and the maintenance of the apparatus is also easy.

Also, the striking member 11, the cleaning brush roller 2
Since the brush roller 1 and the rinsing brush roller 31 are disposed on the lower side of the rug, it is possible to effectively collect dust, a rinsing liquid, and the like that have been knocked down from the rug by utilizing gravity. Further, since the respective processes of the beating unit 1, the washing unit 2, and the rinsing unit 3 are arranged horizontally, it is possible to separately collect the trash and the rinsing liquid that have been knocked down.

It should be noted that the present invention is not limited to the above-described specific embodiments, but may be modified in various ways within the scope of the present invention according to the purpose and application. Other embodiments and modifications can be made. That is, the hitting member may be provided on the rug not on the lower side but on the upper side, or may be hit from the back of the rug. When the beating member is provided on the upper side, no dirt adheres to the beating member, the lifting member, and the like.
