The invention aims at improving such a device. In accordance with the invention, this is achieved in that the cleaning and disinfecting device is fitted to the teat cup or the cleaning member. A cleaning member that is disposed in the teat cup and by means of which the teat is cleaned in the teat cup is excluded in this situation. In a preferred embodiment of the invention, the cleaning and disinfecting device is arranged near the upper side of the teat cup. According to a further inventive feature, the cleaning and disinfecting device comprises one or more spraying elements. According to again another inventive feature, the spraying elements are disposed near the upper edge of the teat cup. According to a further inventive feature, the spraying elements are arranged around the upper edge of the teat cup.
In order to prevent cleaning and disinfecting fluids from being received in the teat cup, according to again another inventive feature, the spraying elements are arranged or designed in such a manner that during operation they spray the cleaning and disinfecting fluids obliquely upwardly from around the opening of the teat cup in the direction of its center line.
According to an inventive feature, the cleaning and disinfecting device is fitted to the outer casing of the teat cup. According to a further inventive feature, this can be provided in a simple manner in that the cleaning and disinfecting device is attached to the teat cup by means of an elastic stocking or shrink stocking.
In accordance with another aspect of the invention, the cleaning and disinfecting device comprises a supply line for supplying the cleaning and disinfecting fluid, as well as a distribution element connected thereto, with the aid of which distribution element the supply line is divided into further supply lines that lead to the spraying elements.
According to again another inventive feature, the device is provided with a milking robot by means of which the cleaning and disinfecting device can be moved towards the teats or be connected to the teats of an animal to be milked.
According to again another aspect of the invention, the device is provided with a withdrawal member for disconnecting the teat cup from a teat. In a preferred embodiment, the milking robot comprises the withdrawal member. According to again another inventive feature, the cleaning and disinfecting device comprises adjusting means with the aid of which the pressure applied or the period of time or both during which the fluid is sprayed against the teat can be controlled or adjusted or both.
The invention further relates to a method of cleaning and disinfecting a teat, in which method, during disconnection or just after disconnecting the teat cup from the teat, cleaning or disinfecting fluid or both are sprayed against a teat by means of a cleaning and disinfecting device.
