Description: The present invention pertains to an automatic machine for the washing and drying of pet animals, such as dogs and similar animals, of the type which basically comprises a cabin having an access door for the animal and being provided on the inside with a series of water and other cleaning and antiseptic liquid spray nozzles, as well as means for drying same. Machines of this type have already been known for a long time. In fact, the same applicant filed European Patent Application No. 0673599, used to limit claim 1, which pertains to a machine according to the preamble of claim 1 and which comprises a cabin provided with entrance and exit doors for the animal, a grated floor and an inclined bottom with drain opening, as well as a pipe-based frame, which has the dual purpose of strengthening the cabin and of being used for the piping of the water and other liquids to be sprayed onto the dog. A double wall which is perforated on the inside is used to distribute the drying air. Inside the cabin, there are two columns with circular tracks, which are used to fasten the collar of the animal while it is being washed. U.S. Patent No. 3884191 describes a machine for the washing and drying of animals, which comprises a cabin provided with means for spraying water and /or cleaning solution onto the animal to be washed, and in which is provided a floor suitable for inclining with the weight of the animal and thus facilitating the displacement of water towards the drain. The drying air is distributed by the same pipes as the water. It also has adjustable means for holding the neck of the animal. On the other hand, U.S. Patent No. 4549502 pertains to an apparatus for washing animals, such as dogs, cats, and including livestock, which comprises a cabin in which the animal is held, sticking only its head out of same. Inside the cabin, there are a plurality of spray nozzles, as well as a plurality of adjustable brushes, with there being provided means for moving the said brushes and for carrying out the brushing of the animal and means for administering hot water and hot drying air through the same spray nozzles. U.S. Patent No. 4505229 also pertains to an automatic machine for washing dogs and similar animals, which comprises a generally cylindrical housing formed by a flat bottom and by two outer walls, between which are arranged a series of annular and contiguous modular elements; inside, there are a series of nozzles connected to washing means and drying means, and these modular elements have a double wall, which defines an intermediate space divided between a plurality of first and second passages connected, respectively, with said washing and drying means and with the nozzles. On one of the outer walls of the machine, there is an opening, through which the animal sticks its head outwards. In the majority of the machines mentioned, it is noted that the animal has it head outside the cabin, which means, on the one hand, that it (the head) has to be washed by hand, and on the other hand, that the animal is tied up. In the machine of European Patent Application No. 0673599, the animal remains entirely inside the cabin, but is also tied up and fastened by the collar, which causes it resulting distress. Except for U.S. Patent No. 4505229, the machines of the other patents mentioned do not provide a water saving and recirculation circuit, but the machine of the said U.S. patent only has one water tank; therefore, in spite of emptying it after the washing of the animal and refilling it with fresh water for its rinsing, fungi and other microscopic residues, which will be cast on each animal with the fresh water, may remain in the same tank. Apart from solving all these problems, the present invention deals with an automatic machine for the washing and drying of pet animals such as dogs and similar animals, which also has other advantages and possibilities which do not exist in the prior-art machines. In fact, the machine of the present invention comprises a cabin with an entrance door for the animal to be washed and a window with an inside light for observing the course of the washing operation and the behaviour of the animal. The inside of the cabin is capable of being divided into two or three compartments for washing two or three small dogs at the same time. The animal is washed by means of exclusive nozzles for this purpose, while the drying with hot air is carried out directly from the opening of a ventilator and the air passes through the inside of the cabin and returns to the air intake of the ventilator through a double ceiling. The same cabin has two other compartments: one for accommodating a hose connected directly to the water supply to carry out a prewashing of the paws of the animal before it enters the cabin or to vigorously clean the floor of said cabin of any possible excrement; the other compartment accommodates bottles of cleaning, antiseptic, softening, etc. liquid with respective distributing pumps for said liquids, as well as an electric control panel. The automatic control of the machine is carried out by means of a computer with keyboard and screen. Moreover, the machine itself has a water recirculation system with two separate tanks: one for the recirculated water and the other for fresh water, so that the latter tank never comes into contact with possible fungi and other microscopic residues. Moreover, in the machine of the present invention, the animal or the animals are never tied up by the neck, but are free to move inside the cabin. In order to facilitate the description below, two sheets of drawings are enclosed, in which: Figure 1 shows an outer front view of the machine according to the present invention with its compartments open, Figure 2 is another sectional front view of the same machine, Figure 3 is an enlarged detail of the section made by the plane III-III of Figure 1, Figure 4 is a front view of a partition wall dividing the interior of the machine, and Figure 5 shows a diagram of the hydraulic water recirculation and renewal circuit for the operations of washing and rinsing the animals and of cleaning the machine itself. According to the drawings (Figures 1 and 2), the automatic machine for the washing and the drying of pet animals, which is the object of the present invention, comprises a general housing (10) provided with wheels (11) for its movement and divided into various compartments: a first compartment or cabin (1); a second compartment (2) that accommodates a ventilator (5) provided with air heating elements (6) as well as with various hydraulic circuit elements (schematically shown in Figure 5); a third compartment (3), which accommodates a hose (7), which is rolled up and has a nozzle (8), which can be turned off by a door (9); and a fourth compartment (4), which is also provided with doors (12), and which accommodates various bottles (13, 14, 15) of the washing, antiseptic, softening, etc. liquids and an electric control panel (16). Above this fourth compartment (4), there is a computer (17) with keyboard (18) and screen (19) to control the automatic functioning of the machine. The cabin (1) is provided with a door (20) for the entrance and the exit of the animal to be washed and with a window (21) and an inside light (22) with a switch (23) for observing the animal while it is washed. The same cabin (1) has a double side wall (24, 25), a double ceiling (26, 27), and a grated floor (28). The same cabin (1) is provided with a plurality of spray nozzles (29) for water and other cleaning, softening, antiseptic, etc. liquids, connected to the distribution pipe (30) passing through the double ceiling (26, 27), through the pipe (31) arranged between the double side wall (24, 25), and through the pipe (32) arranged under the grated floor (28). Nozzles (33) are likewise installed in the edges of the opening (34) of the door (20) that point towards the inside of the cabin (1) (Figure 3). An inclined bottom (35), which leads to a filter (36) detachably installed on the opening of the drain (38), appears under the distribution pipe (32). To facilitate the cleaning or changing of said filter (36), the grated floor (28) consists of various detachable sections (28a, 28b, 28c). On one of the walls (39) of the cabin (1), there is a grated opening (40), which communicates with the outlet of the ventilator (5) with insertion of the heating element (6). In order to provide a recirculation of the hot drying air (41) coming from the ventilator (5), the inner wall (26) of the double ceiling is interrupted, so that the double ceiling communicates on the one hand (42), with the interior of the cabin (1), and on the other hand (43), with the said compartment (2) of the ventilator (5). There are perforated partitions (44) (Figure 4), which can be detachably anchored in the grated floor (28) and on the inner wall (26) of the said double ceiling, which partitions (44) divide the cabin (1) into two or more parts for washing, if desirable, corresponding animals at the same time. The hydraulic circuit (Figure 5) mainly consists of: the tank (45), the pump (46), the pulsating pumps (47, 48, 49) connected to the bottles (13, 14, 15), respectively, the valves (50, 51), the tank (52), and the pump (53). In the operation, the tank (45) is filled with water from the water supply (100), the valve (50) is open and the valve (51) is closed, the pump (46) drives the water towards the sprayers (9) together with the appropriate liquid from any of the bottles (13, 14 or 15) selected by starting the corresponding pump (47, 48 or 49) with pulsating action, then the water, either alone or mixed with any of those liquids, passes through the filter (36) and the drain (38) to the tank (52). Subsequently, the valve (50) closes and the valve (51) opens, with which a recirculation of water between the sprayers (9) and the said second tank (52) is initiated. When the washing is completed, the rinsing is started, for which the valve (50) opens again and the valve (51) closes at the exact same time as the pump starts (53); the first pump (46) continues to operate, with which fresh water is sent to the cabin (1) and the water in the tank (52) is emptied, which will stop at the sewer (70). Once the animal has been dried by means of hot air produced by the ventilator (5) and the heating element (6) and has exited the cabin (1), a washing operation similar to the above is started, i.e., with fresh water and any disinfectant in order to clean the cabin (1) before another animal to be washed enters. This entire operation is controlled by the computer (17) by means of a suitable program, which is obviously not patentable, and by the orders given through its keyboard (18). The first tank (45) is provided with water heating means (71), means for stabilizing the temperature of the water (72), connected with the said computer (17), and a level gauge (73). As a complement to the hydraulic circuit described, there is the hose with an outer nozzle (8) connected to the water supply (100) by means of a valve (75) to prewash the paws of the animal before it enters the cabin (1) or to carry out a vigorous washing of the interior of said cabin and to clean it of any dirt, as was stated above. There is an emergency switch (60) to stop the machine if necessary.
