Utility Model Implementation

The cleaning device in accordance with figures 1 to 9 has a housing (6), which is expediently made of metal, in particular, of stainless steel sheet. The housing (6) is suspended and mounted on the wall of the building. On the upper side of the housing (6) there is a control mechanism (10), which is presented in detail in FIG. 5 and is described in more detail there.

Inside the housing (6) there are two chambers, namely the first chamber (7) and the second chamber (8). The chambers (7 and (8) are separated from each other by a vertical partition (21). On the side of the chamber (7) is limited to the side wall (31), and the chamber (8) is limited to the same side wall (32). At the bottom of the chamber (7) and ( 8) are limited by the bottoms (17), (19) and the front by the front wall, which runs approximately one quarter of the height of the housing (6). On the rear side, each of the chambers (7 and (8) is limited by the rear wall (33), and the rear walls (33) in this embodiment are connected to each other as a whole.However, it is also possible to equip each of both chambers (7) and (8) separately, singly rear wall or generally rejection of the second chamber (8), which is explained in more detail below.

The first chamber (7) serves actually to clean the spray gun with cleaning fluid, while in the second chamber only drying of the spray gun is possible. Of course, drying does not have to take place in the chamber of the cleaning device, but can also occur outside. However, it is highly preferable for the user to dry the spray gun in the same place as the cleaning.

Below the building (6) and outside it, on the floor of the building there is a tank (4) (receiver) containing about 10 liters of clean cleaning fluid, so that M can perform many cleaning processes without adding cleaning fluid. In a second, structurally identical reservoir (5) of the same size, which in this embodiment is located on the side, next to the first reservoir (4), it is possible to collect the cleaning fluid used in the cleaning process and supply it for reuse or, if necessary cleaning up. Due to the fact that the collection tank (5) used to receive contaminated cleaning fluid is the same size as the receiver (4) for clean cleaning fluid, many cleaning processes are possible without having to replace the complete collection tank (5) with an empty collection tank reservoir (5).

Of course, another arrangement of reservoirs (4 and (5) outside the housing (6) is also feasible, for example, one after the other, and / or not on the floor of the building, but on a platform elevation. Due to the fact that the reservoirs (4 and (5) provided outside the housing (6), a preferred wall mounting is possible, despite the fact that fluid reservoirs are provided for cleaning such a large volume.

In order to be able to especially collect the cleaning liquid that flows down or drips down during the cleaning process and during the drying process, the bottoms (17), (19) of both chambers (7), (8) are brought together in a guiding device (28), namely in the bath ( 28) made of sheet metal or plastic. The bath (28) is especially clearly visible in FIG.

In one of the bath sections (28), namely in the bottom (17) of the first chamber (7), a drain (18) is provided through which the cleaning liquid collected in the bottoms (17, 19) can drain into the collection tank located below (5) ) The bottom (17) in this embodiment is made in the form of a truncated pyramid, with the top of the pyramid pointing down. A branch (18) is provided at the top of the pyramid. A pipe (30) is mounted on the branch (18), which passes through the inlet pipe (34) provided in the collection tank (5). In this embodiment, conduit (30) is a flexible plastic hose with a diameter of about 50 mm. Together with this, the contaminated cleaning fluid is carried out without problems from the housing (6) to a removable and free-standing collection tank (5) located outside the housing (6).

A particularly good and reliable passage of the pipeline (30) is provided by a guide pipe (35), which is mounted on top of the pyramid (17). Of course, the pyramid (17) can also be replaced by a truncated cone and a similar shape.

In this embodiment, the conduit (30), which here is, as described above, a plastic hose, is freely passed through the guide tube (35). The guide tube (35) ensures reliable passage of the hose (30). In a simpler version, it is possible to abandon the guide pipe for the hose (30) or pipe (30), especially if the metal pipe is selected as the latter.

In another embodiment, it is possible to attach the pipe (30), if necessary also otherwise designed, to the branch (18) or to the bath (28) using auxiliary means, for example, by means of a threaded clamp.

There may be a guide element for the pipeline (30) provided on the tank.

Of course, it is also possible to use tanks that are not in the form of a canister, as in this embodiment. It is also possible to provide smaller tanks or to replace tanks with larger tanks. If necessary, tanks or tanks can be located below the floor of the building or behind the wall of the building.

The cleaning device operates as follows: In the upper region of the first chamber (7) there is a nozzle (1) for cleaning formed by a section of plastic hose that is connected to the transport device (2). The transport device (2) includes a pump, in particular an injection pump, acting as a water-jet pump, which can suck the cleaning fluid from the receiver (4) through a pipe (16) made in the form of a suction hose and transport it to the nozzle (1 ) for the cleaning. Inside the first chamber (7) of the housing (6) below the nozzle (1) for cleaning, the cleaning device (3) is stationary. The cleaning device (3) here is a scrubbing device, namely a cylindrical brush for cleaning. A scouring device (3) may also mean a brush for cleaning or a sponge for cleaning or the like. The brush (3) for cleaning is located at an angle relative to the longitudinal axis of the nozzle (1) for cleaning below the mouth of the nozzle (1) for cleaning. The cleaning brush is preferably located so that its longitudinal axis forms an angle from 30 ° to 60 °, preferably 45 °, with the longitudinal axis of the nozzle (1) for cleaning, as can be seen from FIG. 7. The brush (3) for cleaning is preferably fixedly mounted in the housing (6), however, in the appropriate case, it is possible to adjust its location and its position relative to the mouth of the nozzle (1) for cleaning, for which either the portion of the hose forming the nozzle (1) for cleaning is made with the possibility of pushing it in or out from the part of the body (7) on which the nozzle (1) for cleaning is mounted, and / or the brush (3) for cleaning is placed on the body (6), preferably on its rear wall (33), with the possibility rotation (Fig. 8). In a preferred case, the brush (3) for cleaning is made flexible or resilient. In particular, a spring-loaded attachment of the cleaning brush (3) to the housing (6) is possible with overcoming the reverse force. In front of the cleaning nozzle and brush (3) for cleaning in this embodiment, a mudguard (23) is located.

In the second chamber (8) there is a drying nozzle (9), to which air for drying is supplied and which is formed, like the nozzle for cleaning, by a section of a plastic hose.

Above both chambers (7), (8), a control mechanism (10) is provided that allows you to control the functions of the cleaning device. The control mechanism (10), shown in detail in a plan view (with the case open) in FIG. 6, has a rectangular body (25) that is closed by a cover not shown in FIG. 6. In the side walls of the housing, connecting fittings (11) are provided for the inlet of compressed air and (12) for the outlet of compressed air. The compressed air inlet (11) is preferably connected to a compressor. At the outlet (12) of compressed air, the compressed air supply pipe supplies air under pressure to the spray gun (S), for which one end of the compressed air supply pipe is connected to the outlet (12) of the discharge air, and the other end to the inlet (38) of the discharge air spray gun (S). Inside the housing (25) of the control mechanism (10), a gearbox (13) is provided, which allows you to adjust the air pressure set in the attached spray gun (S). To regulate the air pressure in the spray gun (S), a multi-position switch (14) is provided in the front of the housing. This multi-position switch (14) selects between the cleaning mode and the spraying mode. When operating in spraying mode, the air pressure at the inlet of the charge air (11) is completely supplied to the outlet (12) of the charge air and thereby to the attached spray gun (S). In this functional position, it is possible to use an attached spray gun (S) for spraying liquid, in particular for varnishing in the usual way.

For a quick manual cleaning of the spray gun (S) by means of the multi-position switch (14), in the embodiment of FIG. 6a made in the form of a three-way valve, the operation of the cleaning device is turned on. In the cleaning mode, the air pressure that is available at the outlet (12) of the compressed air is reduced by the gearbox (13) compared to the air pressure at the inlet (11) of the compressed air. At the same time, in the cleaning mode, a clean cleaning liquid is supplied from the receiver (4) to the nozzle (1) using a transport device (2). For manual cleaning of the spray gun (S), when the cleaning mode is installed on the cleaning device, the latter is introduced into the first chamber (7) and is located in such a way that the cleaning liquid flowing from the cleaning nozzle (1) can penetrate the spray channel in particular into the paint inlet for the spray gun (S), as shown in FIG.

To do this, the spray gun (S) is placed below the mouth of the cleaning nozzle (1), as shown in FIG. 7, and the end of the hose with the cleaning nozzle (1) is placed in the paint inlet of the spray gun (S). In this position, the front of the spray gun, in which the removable air nozzle is located, touches the brush (3) for cleaning. In order to clean the front of the spray gun (S), i.e. in particular the air nozzle, the spray gun is manually moved up and down and / or to the sides, so that the surface, in particular of the removable air nozzle, rubs against the brush for cleaning. As a result, the remaining varnish is removed from the surface of the spray gun by friction. Thus, the spray gun (S) during the cleaning process is cleaned both outside and inside, that is, in the spray channel.

In order to clean the spray channel of the spray gun (S) as efficiently as possible and save cleaning agent, it is advisable to supply a mixture of air and cleaning agent from the nozzle (1) to the spray channel of the spray gun (S). For this, compressed air is supplied to the transport device (2), which it mixes with the cleaning liquid from the receiver (4). To this end, the transport device (2), as described above, preferably has an injection pump configured as a water-jet pump, which is connected to the compressed air inlet (11) through a gearbox (15) located in the housing (25) of the control mechanism. This pump, driven by compressed air from the compressed air inlet (11), transports the cleaning liquid from the receiver (4) through the suction hose (16) and mixes it with compressed air at the same time, resulting in a mixture of air and cleaning agent, the action of which in the cleaning mode of the device, the nozzle (1) is exposed for cleaning. In general, 100 ml of cleaning fluid is consumed in the cleaning process. Thus, in combination with the ten-liter tanks described above (4 and (5), it is possible to use the cleaning device frequently without having to replace the liquid tanks.

After cleaning the spray gun, it is removed from the first chamber (7) and transferred to the second chamber (8). In the second chamber (8), the cleaned spray gun (S) can be dried by means of a drying blower nozzle (9), for which the spray gun (S) is kept in the air stream of the drying blower nozzle (9). To actuate the drying blower nozzle (9), a control button (24) is provided, which, when pressed, allows the supply of compressed air from the compressed air inlet (11) to the blower blower nozzle (9) through the bypass channel (26). When drying the spray gun (S) by blowing, the remaining cleaning fluid is removed from the surface of the spray gun (S) and also from its spray channel. Drops of cleaning liquid flowing down from the spray gun (S) are collected on the flat bottom (19) of the second chamber (8). The bottom (19) of the chamber (8) has a slope in the direction of the bottom (17) of the opposite chamber (7), so that the liquid collected on the bottom (19) is able to drain to the bottom (17) and through the outlet (18) into the collection tank.

Moreover, in this embodiment, the residual liquid is collected especially simply and efficiently, since the bottom (17) has the shape of a pyramid directed downward. Through the above-described pipeline (30), made in the form of a discharge hose, the remaining liquid is transferred without loss to the collection tank (5). The pipeline (30) is in turn protected from unwanted movements by means of a guide pipe (35). In this case, it is possible to fix the guide pipe (35) on the bottom in any way or to make it as a unit with the bath (28).

It is also permissible to have a transport device, for example, a pump, preferably between the reservoir (4) and the outlet (18), which makes it possible to especially quickly transport the contaminated cleaning liquid.

After the cleaning and drying process is completed, the spray gun (S) is again removed from the second chamber (8), and the cleaning device is switched to the spray mode by the multi-position switch (14). After this, it is again possible to use a manually cleaned spray gun (S) in the spray mode for spraying liquids, in particular for varnishing. When transferring the cleaning device from the cleaning mode to the spraying mode, it is possible to stop the supply of cleaning agent to the nozzle (1) for cleaning, and at the same time the pressure available at the inlet (11) of the compressed air is completely supplied to the outlet (12) of the compressed air. Variants of this solution are possible, in particular, intermediate positions during switching.

Figure 6 shows a simpler version of the control unit (10). Air is throttled by the device; purge air is supplied automatically. Instead of a three-way valve (14), a simple rotary knob (14a) is provided as a multi-position switch. Attaching a spray gun is not required. Otherwise, the details and functions may be the same as in the control unit of FIG. 6; the same parts are indicated under the same designations.

In certain embodiments, the need may be omitted for the foreseen foreseen connection of the spray gun. Permissible quick coupling via magnet (s) or equivalent.

In the embodiment of Fig. 9, which is arranged and functions essentially the same as the variant shown in Fig. 1 (the same parts are provided with the same designations), an opening (36) is provided in the side wall of the first chamber (7 ) A suction hose (37) or a suction pipe is inserted into this hole (36) and secured, for example, by means of a connection (39) by means of clamps. When a pumping device is not required and / or when the cleaning device is not used, as well as for transportation purposes, the opening is closed by means of a lid or plug (40).

The provided pumping can reduce the unpleasant odor and health hazard caused by the cleaning fluid. Moreover, the pumping device is not necessarily provided in the side wall (31); in particular, in large cleaning devices, it can also be provided in the bottom area.

Parts (37) and (40) are preferably made from synthetic materials, in particular from flexible synthetic materials.

In the embodiment of FIG. 9 and FIG. 10, the front wall (41) of the housing (6) is made in the form of a movable hinged cover. This makes it particularly easy to access the cleaning device (3) and the bath (28).

In order to further simplify the cleaning, repair and maintenance of the cleaning device, the control mechanism (10) is configured to be disconnected from the housing (6). The housing (25) of the control mechanism (10) is covered with a housing cover, the housing cover preferably having walls protruding upward on the sides. This makes it possible to use the housing cover (25) as a surface for storing and storing spray accessories - for example, paint containers.

Of course, other structural parts and embodiments of a cleaning device are possible.

In a generalized form, all the described cleaning devices have the particular advantage that, due to the presence of freely standing liquid tanks located outside the housing, they are lighter than previously known embodiments. Therefore, without problems it is possible to use them in the form of hanging devices on the walls. The utility model is based on the task of creating a working tool of a normal form, which has a simple construction and which avoids errors in management.
