Description

technical area

The invention relates to a rinsing device for the manual washing and rinsing of drinks glasses, in particular beer glasses with handles, optionally glasses with handles for coffee, tea and lemonade, and includes: the washing vessel with the mechanical brushes, possibly a hanging tub with the effective chemical rinsing agent. The washing vessel has a central washing mandrel. The rinsing tank/rinsing unit has a central rinsing spike and lateral sprayers. The rinsing device has a water supply to the washing vessel and to the rinsing vessel/rinsing unit with a water outlet. It is also provided with a common base and adjustable valve heads.

The current state of the art

The flushing device is known and manufactured by the owners of SCHICKER & SCHAEFER GmbH, Wuppertal DE, which is protected by patents CZ 294 050 and DE 299 10 353 from 1999 with the designation "Device for cleaning and rinsing of beverage containers". The system consists of an open pre-wash pot with removable brushes and an adjacent rinsing system with a vertical pipe for the water supply. The rinsing system and the pre-wash pot are connected by a common water supply and are fixed in the base, which forms a hollow body and inside which there is the water supply for the pre-wash. The water flows through the pre-wash tank and is discharged from above into the rinsing tank with brushes, from where it is discharged through a side drain. Basically, the base is made of plastic, which is closed watertight and in which there is a sealed opening for the connection piece for attaching the water hose for a common water connection. The connection socket functions as a closing cover and is sealed to the outside with a ring seal both on the threaded socket and on the through-opening in the base. The post-rinse vessel, optionally also the washing vessel, can basically be cylindrical vessels open at the top. The advantage of this solution is that the watertight closed base is encapsulated against any contact with the water and has an externally accessible connection piece for the water hose. The advantages and disadvantages of this solution can be that the watertight closed base is assembled, watertight closed and encapsulated directly by the manufacturer.

A vessel washing device from the owner of DUNET GmbH, CZ, which, among other things, is registered as utility model CZ 32 325 and the corresponding utility model DE 359 07 269 from 2004 is protected, is known and is being produced. The washing device has a common base. Both containers, the washing and the rinsing container, are separated from each other by a common partition. This basic design of the DUNET ^® washing device with the important basic technical properties is used to this day.

The owner of DUNET GmbH, CZ, had also protected individual components of the washing device as a utility model: CZ 30 579 and DE 40 40 72 69 for the shape of the washing and rinsing containers; CZ 311 668 and DE 40 30 53 08 for the support of the washing device; CZ 31 567 and DE 40 30 47 88 for the hanging tub for the detergent pellets in the washing vessel; as well as CZ 31 562 and DE 40 30 47 87 for the cleaning and disinfection pellet.

In CZ 296 462 B6 and in corresponding ones WO 2007/038904 A1 describes another improved washing device owned by DUNET GmbH, Prague, CZ. This washing device produced has a rinsing unit, the side rinsing nozzles of which can be rotated and movably adjusted with respect to the rinsing mandrel. The lateral rinsing nozzles are attached to the upper part of the ring-shaped base body, which is free-standing on the base. The ring-shaped base body has a central opening which is connected on the one hand to the interior of the rinsing mandrel which opens into the main nozzle, and on the other hand to the inner ducts via a side opening which adjoins the side ducts and which open into the side nozzles of the side rinsing nozzles. The side rinsers are formed by the outer part and the inner part facing the rinse mandrel and have a side sprayer. These two parts are detachably connected to each other. The outer surface of the washing vessel and the rinsing unit, or their suitable components, are provided with a preferably elastic protective cover. This washing device consists of a washing vessel and a rinsing unit standing on a hollow base in which there is a hollow carrying holder and a common connection for the pressurized water into the washing vessel and the rinsing unit. The washing water flows out of the washing vessel via a pipe located above the floor, the rinsing water flows out of the rinsing unit via the inner cavity of the rinsing mandrel of the rinsing unit.

The advantage of this invention is simple and safe manipulation by operating the washing device and spraying the side rinse in case of lack of work space or saving of work space. During the working process, the operator can turn the side rinsers to the desired angle and position with the side spray, which allows easy and safe operator access when putting the glasses into the rinse unit. In addition, this solution according to the invention allows, with a simple structural change, to reduce the size of the rinsing device and its weight, and therefore also a reduction in the dimensions and weight of the entire washing device.

All of these types of manual washers share a common disadvantage. So far, only cold water has been used for washing and the subsequent rinsing. Even if the washing of the glass with cold pressurized water is additionally reinforced by mechanical cleaning with the central and edge brushes, as well as with a chemical agent dissolved in the cold washing water, it can still happen that even such washing does not completely remove any impurities and Oiliness removed from the glass surface. With regard to the subsequent rinsing of the glass with cold pressurized water, this loses its effect if the washing is not perfect.

The font CZ 298 756 B6 and the corresponding one DE 10 2007 051 100 of the owner of the DUNET GmbH, CZ describes a solution of a glass washing device for the manual washing and rinsing of beverage glass, in particular of beer glasses with a handle with a possible use of cold or warm water. The wash vessel and rinse unit each have their own separate direct supply of either cold or warm water. Each of these inlets is connected to either a cold or hot water outlet and is separated by a partition in the support bracket. The washing vessel and the rinsing unit are attached to this support bracket. The holder here represents an important supporting construction element of the entire washing device. The hollow holder is provided with a vertical partition which separates the water distribution for the washing water and the rinsing water.

This solution with the partition wall can be produced in a relatively complicated manner with high investment costs and is also expensive to operate. In addition, it has been shown in pilot plants and in practice that this type of support bracket and the partition located in its center separating the water distribution represents the weakest element of the washing device. The partition wall of the holder is mechanically and thermally stressed and impurities accumulate in its corners. Because of this, this washing device did not achieve widespread use, e.g. H. the previously intended use of hot water in the water distribution of the washing device in at least one of the washing or rinsing vessels.

Basically, the disadvantage of these existing washing devices consists in only one real water supply, and this either only for cold or only for warm water for washing and rinsing.

The aim of this invention was to achieve a safe constructional separation of the two distribution systems of the water, the washing and the rinsing water, with the existing washing devices, with the possibility of using lukewarm to warm water.

The gist of the invention

The washing device for manual washing and rinsing of drinking glasses, in particular beer glasses with a handle, possibly for glasses with a handle for tea and lemonade, according to the invention, eliminates the disadvantages mentioned. The washing device consists of two basic components, the washing vessel and the rinsing vessel/rinsing unit. The washing vessel is provided with mechanical brushes, is optionally equipped with a hanging tub for an effective chemical cleaning agent and has a washing mandrel. The rinsing vessel/rinsing unit has a central rinsing mandrel and lateral sprayers. The washing device has a water inlet into the washing vessel and the rinsing vessel/rinsing unit, a common base and adjustable valve heads.

The essence of this invention is that the manual washing device has separate washing and rinsing circuit. Each valve head, washing and rinsing head, has its water supply, which are connected to each other with independent separate water supply of the hollow connecting middle part, which has a separate independent washing water circuit for washing the beverage glasses in the washing vessel and an independent rinsing circuit for rinsing the beverage glasses in the rinsing vessel/ in the rinsing unit, whereby the pressurized washing or rinsing water is either cold or warm in the range from 25 to 50°C, possibly lukewarm in the range from 35 to 40°C. The washing vessel has its direct inflow of pressurized washing water from the adjustable one Washing valve head, which is connected to the direct inflow of the pressurized washing water on the other side. And the rinse vessel/unit has a direct inflow of pressurized rinse water from the adjustable rinse valve head which is connected to the direct inflow of rinse wash water on the other side. Overall, the valve head has been specially designed for the purposes of the washing device according to this invention.

The connecting center part can be a hollow tube which is connected to the valve head and which is connected to the water supply on the other side. The connecting means may be an external hollow bulge of the valve head which is connected to the water inlet by means of a hollow connector. The hollow bulge on the body of the valve head can advantageously be firmly connected to the connecting part to form a whole. The hollow connector is usefully a connector elbow or a hollow tube. For example, in the case of a connecting elbow, the hollow bulge on the body of the valve head is arranged horizontally and is connected to the horizontal part of the right-angled connecting elbow, the vertical part of which faces downwards and is connected to the water inlet.

It is advantageous if each valve head has an external central thread for securing the sealing ring under the bottom of the base and for screwing the valve head into the opening of the base.

It is also advantageous if the lower part of the valve head is sealed with a rigid plastic closing cap with a metal nut embedded in the center.

Furthermore, it is advantageous if each valve head has an upper thread for a cover nut on the upper edge of the body for fastening the valve head in the washing vessel and in the rinsing vessel/in the rinsing unit.

The washing vessel and the rinsing vessel/rinsing unit rest on a common trough-shaped base, the bottom of which has flat bulges protruding above the floor on the side facing the washing vessel and the rinsing vessel/rinsing unit.

The bulge located under the washing vessel and the rinsing vessel has two continuous openings for the washing water connection and rinsing water connection; two openings for fastening the valve heads in the base, these openings being covered by spacer screws outside the bottom of the base; and four support pins to stabilize the valve heads in the base.

The bulge located under the washing tank and the rinsing unit has: two through openings for the washing water connection and rinsing water connection, two openings for fastening the valve head in the base, these openings being covered by spacer screws outside the bottom of the base, and three supporting pins for stabilization the valve heads in the base.

The trough bottom of the pedestal under the wash tub and the rinsing tub has two openings for draining the washing and rinsing water, the trough bottom of the plinth under the washing tub and the rinsing unit has one opening for the draining of the washing and rinsing water.

The base is provided with four suction cups on the outside for attaching the washing device to the base.

The main advantage of the washing device according to this invention consists in the separate water supplies for washing and rinsing water, which allows simultaneous use of cold and hot water for the washing device, which improves hygiene during washing and subsequent rinsing and the utility properties of the Washing device improved by a more complete degreasing and removal of impurities from the glass surface, which is given by the separate connections and the subsequent water supplies with cold or lukewarm to warm washing water, or with cold or lukewarm to warm rinsing water.

In particular, the use of warm water has a significant impact on the cleanliness and speed of washing. The washing water for washing in the washing vessel and the rinsing water for rinsing in the rinsing unit are supplied separately from one another and regulated by means of washing and rinsing valve heads that can be regulated separately from one another. Such a separation is desirable in particular when using pressurized warm washing water or pressurized warm rinsing water. This regime with warm washing water and warm rinsing water is particularly suitable for heavily soiled beer glasses and drinks glasses for tea, coffee or lemonade. The regime "warm washing water and cold rinsing water" is suitable for a usual regime in restaurants, especially for washing beer glasses, at where a warm glass is unsuitable for chilled beer, which thereby loses its flower. The regime "cold washing water and warm rinsing water" is suitable for drinking glasses for tea and lemonade. The cold washing water and cold rinsing water mode is suitable, for example, for additional washing and rinsing of heavily soiled glass washed in the “warm washing and warm rinsing water” mode.

The connections for the washing and rinsing heads are always separate from one another, but routed directly via the corresponding valve head for entry into the washing unit or entry into the rinsing unit.

The use of pressurized hot water naturally places higher demands both on the actual material of the washing device and on its surface that comes into contact with the hot water. A material that can withstand temperatures of around 80 to 100°C over the long term has been used for all parts and surfaces that come into long-term contact with warm pressurized water.

According to this invention, the applicant DUNET GmbH of the washing device continues to work continuously on the development of its washing devices for washing and rinsing glasses. According to this invention, the washing device was developed on the basis of customer requirements for washing and rinsing with hot water in a particularly epidemiologically demanding time. In the majority of the existing washing devices of the owner of DUNET GmbH, the washing devices have a support bracket which carries the washing and rinsing heads at their ends and are provided with only one common water inlet for washing and rinsing. In addition, this bracket is an important support element of the existing washing devices from DUNET GmbH. According to this invention, the new washing device has a design change that represents a completely fundamental break in the design of the new washing device that has been relieved, the safe and proven separation of the washing and rinsing water with targeted use of the safely separate circuits for warm and cold water allowed. This is made possible by the design of the new type of valve heads for the new type of washer and the changed base of the washer. The existing types of washing vessels and rinsing vessels/rinsing units remain unchanged.

A great advantage of the non-electric manual washing device according to the invention, with a large part of its components being made of hard plastic, is that it can be repeatedly dismantled without hand tools, which allows cleaning of 90% of the components of this non-electric manual washing device in a standard electric dishwasher.

Another great advantage of the washing device according to the invention is the manual and intuitive disassembly of the basic components of the washing device, even in a new arrangement, without any tools. For example, the washing vessel can be detached from the base, which is particularly subject to contamination. The central brush or the outer brushes can be removed from the wash tank just as easily. All of these parts of the washing vessel can be placed in a conventional electric dishwasher; and the more frequently this maintenance of the washing vessel is carried out, for example daily or even several times a day, the longer the service life of the washing device is. The rinsing container/rinsing unit can also be removed from the base. The central spray nozzle with the side sprayers can also be removed. However, it is not necessary to clean these parts of the rinse as often. It is recommended to clean the base from time to time, although the operator can do this during ongoing operation if necessary. The base has a mounting hole in its bottom with bolts and nuts of such a size that the base can be easily and repeatedly disassembled by hand and without any tools whenever the need arises. The trough-shaped base is therefore easily removable from the two vessels, the washing vessel and the rinsing vessel/rinsing unit.

The dismantling of the washing device according to this invention also has other advantages. In the event of a failure in any component of the washer, that component can be easily replaced and there is no need to purchase a new complete washer. If a customer has an older type of washing device from DUNET GmbH and wants the new type of washing device according to this invention, he can use the washing vessel and the rinsing vessel or the rinsing unit from the older type of washing device and it is enough just the new valve head and buy the new base of the washing device according to this invention.

example 1

A washing device 1 with a washing vessel 2 and a rinsing vessel 3

(Figs. 1 to 6 and 13 to 15)

The washing device 1 for the manual washing and rinsing of beverage glasses, in particular beer glasses with a handle (not shown), is shown in a concrete example of the embodiment in the axonometric view in and the supervision from above in shown. The washing device 1 consists of the washing vessel 2 in the rinsing vessel 3 attached next to it. Both vessels 2, 3 have a cylindrical shape and are separated from one another by a common partition. The washing vessel 2 and the rinsing vessel 3 from the owner of DUNET GmbH, CZ, are used, which, among other things, are covered by utility model CZ 32 325 and the corresponding utility model DE 359 07 269 from 2004 are protected.

The washing vessel 2 and the rinsing vessel 3 are mounted on a common hollow base 4 so that they can be removed. The hollow base 4 can be formed as a trough-shaped body with profiled side walls with an open upper part and with an upper edge, in which both the washing vessel 2 and the rinsing vessel 3 can be inserted with a margin and without any seals.

The washing vessel 2 has a cylindrical shape. In the vicinity of the connecting wall, the washing vessel 2 is provided with two lateral bulges 5 extending over the entire height of the washing vessel 2 . The bulges 5 bulge outside the washing vessel 2 and show a semi-circular shape in section. The two bulges 5 aligned perpendicularly opposite one another have the same height as the body of the washing vessel 2 . The bulges are open at the top and have a bottom which adjoins the bottom of the washing vessel 2 . One of these bulges 5 is intended for free insertion of the glass handle with scope for its easy rotation. The lower part of one of these bulges 5 can serve as an overflow 51 and outlet for the pressurized water. A perforated trough 6 can be hung on the upper circumference of the washing vessel 2, next to the outer washing brushes 14b, at any desired location except the bulges 5, as in FIG is pictured. The tub 6 is hung above the water surface or just below the water surface of the flowing water. A solid cleaning agent, for example in the form of pellets, can be placed in the trough 6 to facilitate washing and chemical cleaning of the beverage glasses.

The washing vessel 2 has mechanical brushes 14a and 14b as shown in the left part of FIG is evident. The central mechanical brush 14a is located on the washing mandrel 7 mounted vertically and centrally; the second brush 14b running belt-like along the inner circumference is fastened in grooves 2b of the washing vessel 2 located on the inner circumference.

In the right part of the washing device 1 in the rinse vessel 3 is shown. The rinsing vessel 3 has a central rinsing mandrel 8 with the main water sprayer 8a and two oppositely oriented side rinsers 9 with the water sprayers 10.

The inlet 12 for the wash water and the supply line 22 for the wash water are connected to the wash water distribution 42 tied together. shows the adjustable rinsing water valve head 33 with its own connection 13 for the pressurized rinsing water into the rinsing vessel 3, as well as its own supply line 23 of the rinsing water into the rinsing water valve head 33. The connection 13 for the rinsing water and the supply line 23 of the rinsing water are associated with the distribution of the rinse water 43. Both valve heads 32 and 33 are in the and with their supply lines 22 and 23 situated opposite one another, as they are arranged in the washing device 1. In reality, both valve heads 32 and 33 are completely identical in construction.

One of the bulges 5 in the washing vessel 2, in which the overflow for the water 51 is located, can serve as the water outlet from the washing vessel 2. The water drain from the washing vessel 2 can be formed by a drain pipe, not shown, which, starting from the washing vessel 2, leads out loosely and with clearance through the hollow base 4, so that the opening 24 for the water drain in the bottom of the base 4 is not extra in normal operation is sealed. The drain from the rinsing unit 3 is solved in such a way that the rinsing water flows off via the drain pipe 31 which is located in the lower part of the rinsing vessel 3 . The outflow of the washing and rinsing water through the opening 24 in the bottom of the base 4 is also through the actual tubs shaped base 4 favored with a relatively high edge in which the water collects.

The axonometric view in shows the washing device in the disassembled state. The upper part shows in the axonometric view the washing vessel 2 in the vertical axis 2a and the rinsing vessel 3 in the vertical axis 3a, under which the two same valve heads 32 and 33 oriented opposite in the washing device 1 are situated. Below both valve heads 32 and 33 the common base 4 is shown axonometrically.

The dismantled components of the washing device 1 are in shown as they are arranged in the washing device 1 in reality. In the finished washing device 1, the axis 2a of the washing vessel 2 runs through the vertical body axis 15 of the washing valve head 32 and connects to the opening 4a for fastening the washing valve head 32. Another axis 16a, which leads through the vertical part of the connecting elbow 16, connects to the through-opening 4c for the supply line 22 of the washing water into the washing valve head 32. In the finished washing device 1, the axis 3a of the rinsing vessel 3 runs through the vertical body axis 15 of the rinsing valve head 33 and connects to the opening 4b for fastening the rinsing valve head 33. A further axis 16b, which runs through the vertical part of the connecting elbow 16, connects to the continuous opening 4d for the supply line 23 of the rinsing water into the rinsing valve head 33.

The axonometric view of base 4 is shown in shown in plan view from above. In the bottom of the base 4, on the inner side of the bottom, there is a protruding bulge 4j in the shape of the figure “8”, facing the washing vessel 2 and the rinsing vessel 3, in which the openings 4a, 4b, 4c and 4d are located. In the left part of of the bulge 4j of the base 4 under the washing head 32 there is an opening 4a for fastening the washing valve head 32 in the base 4, the through opening 4c for the inflow 22 of the washing water into the washing valve head 32 and two supporting pins 4e for fitting and stabilization of the washing vessel 2 in the base 4. In the right part of the The bulge 4j of the base 4 under the rinsing vessel 3 contains the opening 4b for fastening the rinsing valve head 33 in the base 4, the through opening 4d for the inflow 23 of the rinsing water into the rinsing valve head 33 and two supporting pins 4f for fitting and stabilization of the rinse valve head 33 in the base 4.

The axonometric view of base 4 is in shown as a bottom view of the outside of the base 4. The bulge 4j is located higher than the bottom of the base 4. The bulge 4j has been enlarged in area compared to the applicant's existing washing devices. The areal increase in length and width causes greater strength of the bottom of the base 4. In the existing DUNET washing devices there is only one opening for water supply from the holder. The enlargement of the bulge 4j also creates a more favorable place for the supply hose, which is not shown. On the outside of the bulge 4j in the bottom of the base 4 are two spacer screws 4g and 4h. The nut of the spacer screw 4g for fastening the wash valve head 32 and the nut of the spacer screw 4h for fastening the rinse valve head 33 .

On the outer periphery of the bottom of the base 4 there are four suction cups 4i for adhering and stabilizing the washing device 1 to an unillustrated support such as an unillustrated sink.

A new element of each valve head 32 and 33 in the sample preparation is the right-angled connecting elbow 16, which is provided with a thread at its lower end, to which the water hose, not shown, is screwed. The hollow connecting elbow 16 is part of the valve head and water supply 42 and 43. Another new element of the valve head 32 and 33 is the cover 19 which replaces the original metal nut of the valve head 32 and 33 made of brass or stainless steel. The lid 19 is made of hard plastic and has a metal nut 19a in the center. The nut 19a is made of brass or stainless steel. The cover 19 is significantly easier to assemble and allows easier access (compared to the original metal nut) into the valve head 32 and 33, for example in the event of a service intervention.

Another new advantageous element is the sealing ring 18 made of soft plastic, which seals and at the same time equalizes the space between the surface of the washing tank 2 or the rinsing tank 3 and the base 4.

The washing device 1 works as follows:

According to the invention, the manual washing device 1 is usually placed in a sink with running water. In this space, which is usually very cramped, the possibility of the reversibly adjustable and rotatable side rinser 9 of the rinsing vessel 3 increases the functional properties of the manual washing device 1, especially when rinsing beer glasses with handles. The operator can thus place the beer glasses with handles on the central rinsing mandrel 8 there , where there is space and does not have to twist the entire washing device 1 in a difficult way.

The supply circuits with washing and rinsing water are separate from each other and are independent. The wash water supply circuit comprises the pressurized wash water connection 22 and the wash water inlet 12 into the wash tank 2 via the adjustable wash valve head 32. The wash water is fed from the connection 22 into the inner space of the water distribution 42 of the valve head 32 via the connecting elbow 16 and the water distribution 42 into the separate inlet 12 of the wash valve head and then into the wash vessel 2 . The water distribution of the rinsing water comprises the connection 23 for the pressurized rinsing water and the entry 13 of the rinsing water into the rinsing vessel 3 via the adjustable rinsing valve head 33. The rinsing water is supplied from the connection 23 via the inner space of the water distribution 43 of the rinsing water valve head 33 via the connecting elbow 16 brought up and routed via the water distribution 43 into the separate inlet 13 of the rinsing valve head 33 and into the rinsing vessel 3 . Both separate valve heads 32 and 33 are in the common base 4.

Washing in the washing vessel 2 proceeds as follows: the operator places the beer glass (not shown) upside down at the upper end of the washing mandrel 7 with the central washing brush 14a in such a way that the handle is pushed into one of the bulges 5 . The operator presses the bottom of the beer glass on the washing mandrel 7 ( and ). Thus, pressurized water is let into the washing mandrel 7 via the channel-like interior from below, which water acts on the inner surface of the glasses by means of the central sprayer 8a of the washing mandrel 7 . A mechanical brush 14a on the washing mandrel 7 helps to wash the inner glass surface. The water flows from the washing mandrel into the space of the washing vessel 2 and this water together with a belt-like brush 14b running along the inner circumference serves to clean the outer surface of the glasses. Chemical agents - detergents of various types, both in liquid and solid form, increase the effectiveness in cold and warm water. In the case of cleaning agents in solid form, such as pellets, which are placed in the hanging tray 6 ( ) are inserted, their gradual dissolution and effect occurs when they come into contact with the washing water.

This is followed by rinsing in the rinsing vessel 3. The operator places the washed glass in the rinsing vessel 3 on the centrally arranged rinsing mandrel 8 with the bottom facing up. The operator then exerts slight pressure on the base of the glasses and on the rinsing mandrel 8. This initiates the inflow of pressurized water into the rinsing mandrel 8 with the central sprayer 8a for rinsing the inner surface of the glasses on the one hand, and into the two side washers 9 with the side sprayers 10 for rinsing the outer surface of the glasses on the other.

example 2

A washing device 1 with a washing vessel 2 and a rinsing unit 30

(Figs. 7 to 12 and 13 to 15)

The washing device 1 for the manual washing and rinsing of beverage glasses, in particular beer glasses with a handle, is shown in a concrete example of the embodiment in the axonometric view in and supervision from above in shown. The washing device 1 consists of the washing vessel 2 of the same construction as in the previous exemplary embodiment and next to it there is the rinsing unit 30. The washing vessel 2 and the rinsing vessel 3 of the owner of DUNET GmbH, CZ were used, which are described, for example, in the document CZ 296 462 B6 to be described with Scripture WO 2007/038904 A1 corresponds or in writing CZ 298 756 B6 , corresponding to DE 10 2007 051 100 .

The washing vessel 2 and the rinsing unit 30 are detachably inserted into the common hollow base 4 . The hollow base 4 can be formed as a trough-shaped body with profiled side walls with an open top and with an upper rim into which the washing vessel 2 can be inserted with a margin and without any seals.

A concrete example of the construction of the arrangement of the rinsing unit 30 according to this invention, the central rinsing mandrel 8 and the two opposite side rinsing devices 9 are arranged vertically on an annular base plate 11 and evident. The rinsing unit 30 is placed in the upper edge of the trough-shaped body of the base 4 in such a way that the annular base plate 11 with the central opening is freely placed on it, through which the rinsing mandrel 8 passes, the lower end of which is attached to the rinsing valve head 33. The annular base 11 has two opposite semi-circular spurs, on each of which two opposite side flushers 9 in the form of "fins" or "needles" are firmly attached, as can be seen in FIGS , and is evident.

represents the wash valve head 32. 1 shows the post-rinse valve head 33. Both valve heads 32 and 33 are oriented opposite to each other as they are oriented in the washing device 1 and are structurally identical to those in the previous example 1.

The dismantled components of the washing device 1 are in shown as they are arranged in reality in the car wash 1. In the finished, completed washing device 1, the axis 2a runs through the washing vessel 2, as a vertical axis through the body 15, the washing valve head 32 arranged underneath and connects to the opening 4a for fastening the washing valve head 32. Another axis 16a leads through the through-opening 4c for the supply line 22 of washing water into the washing valve head 32. The further axis 16a goes through the vertical part of the connecting elbow 16 and leads through the through-opening 4c for the inflow 22 of washing water into the washing valve head 32. In of the finished washing device 1, the axis 3a runs through the rinsing unit 30, as a vertical axis through the body 15 of the rinsing valve head 33 and connects to the opening 4b for the attachment of the rinsing valve head 33. Another axis 16b goes through the vertical part of the connecting elbow 16 and leads through the through opening 4d for the inflow 23 of rinsing water into the rinsing valve head 33.

The water outflow from the washing vessel 2 is formed by a pipe which leads out of the washing vessel 2 and is not shown. The tube passes through the hollow base 4 freely and with clearance, so that the opening 24 for water drainage in the bottom of the base 4 is not specially sealed. The outflow from the rinsing unit 30 is structurally similar to that of the washing vessel 2, which means that the rinsing water flows out via the same pipe located in the lower part of the rinsing unit 30. The drainage of the washing and rinsing water through an opening 24 in the bottom of the base 4 is supported by the actual base 4 in the form of a trough with a relatively high rim in which the water collects.

The axonometric view of base 4 is in shown in plan view from above. In the bottom of the base 4, on the inside of the bottom facing the washing vessel 2 and the rinsing unit 30, there is a protruding bulge 4k of elongated shape occupying a smaller area compared with the bulge 4j in the previous example. There are two passage openings 4c and 4d in the bulge 4k and the two openings 4a and 4b in the bottom next to the bulge 4k. left in is in the bottom of the base 4 next to the bulge 4k an opening for the attachment of the wash valve head 32 in the base 4. The bulge 4k is provided with a through opening 4c for the inflow 22 of wash water into the wash valve head 32. right in the opening 4b for attaching the rinsing valve head 33 in the base 4 is located in the bottom of the base next to the bulge 4k of the base 4 under the rinsing unit 30. The through-opening 4d for the supply line 23 of the rinsing water into the rinsing valve head 33 is located in the bulge 4k. The bottom of the base 4 has a support pin 4e.

The axonometric view of the base 4 seen from below is in shown from the outside of the base 4. The elongated bulge 4k is higher than the bottom of the base 4. From the outside of the bulge 4k are located in the bottom of the base 4 two spacer screws 4g and 4h for fastening the wash valve head 32 and for attaching the Nachspülventilkopf 33. On the outer periphery of the bottom of the base 4 are three suction cups 4i for suction and stabilization of the washing device 1 to a non-illustrated surface, for example a non-illustrated sink.

With regard to the arrangement of the valve heads 32 and 33, both have the same construction and the same applies to them as was said in the previous embodiment example with reference to , in which the individual parts of the valve heads 32 and 33 are shown , which shows the valve heads 32 and 33 in front view, and on , which shows their vertical section.

The washing device 1 works as follows:

Beverage glasses, in particular beer glasses, are washed in the same way as described in Example 1 above.

This is followed by rinsing in the rinsing unit 30. The washed glass is placed in the rinsing unit 30 in such a way that the operator places the beer glass upside down onto the centrally arranged rinsing mandrel 8. The operator then exerts slight pressure on the bottom of the glass sitting on the rinsing mandrel. This initiates the inflow of pressurized water into the rinsing mandrel 8 with the central sprayer 8a for rinsing the inner surface of the glass on the one hand, and into the two side rinsers 9 with the lateral sprayers 10 for rinsing the outer surface of the glasses on the other hand.

The arrangement of the post-rinse unit 30 is different according to this invention. According to this invention, the rinsing unit 30 has a rinsing mandrel 8 and two opposite side rinsing devices 9 which are perpendicular to the annular base plate 11 ( and ). The rinsing unit 30 is inserted into the edge of the trough-shaped body of the base 4 in such a way that the ring-shaped base plate 11 with the central opening through which the rinsing mandrel 8 leads lies freely on it.

The ring-shaped base plate 11 with the two permanently connected side flushers 9 is exposed and freely rotatable on the hollow base 4, against which it is pressed by the central final flushing mandrel 8 with the central sprayer 8a. When the ring-shaped base plate is turned, the central post-rinse mandrel 8 remains in its place and the two side flushers 9 with the side sprayers 10 are deflected with the ring-shaped base plate 11 . This twisting of the ring-shaped base plate 11 with the two side flushers 9 (in the form of “fins”) can be carried out manually by the operator. In this way, the operator can easily return the two side flushers 9 to their original position manually as required.

The following summary applies to both example executions:

• • warmes Waschwasser und warmes Nachspülwasser;
• • warmes Waschwasser, kaltes Nachspülwasser;
• • kaltes Waschwasser und warmes Nachspülwasser; gegebenenfalls auch
• • kaltes Waschwasser und kaltes Nachspülwasser.

Basically, there are four variants of the inflow 22 of washing water into the washing vessel 2 and the inflow of rinsing water into the rinsing vessel 3/the rinsing unit 30 of the washing device 1. The washing device 1 can work in the following regimes:

• • warm washing water and warm rinsing water;
• • warm wash water, cold rinse water;
• • cold wash water and warm rinse water; possibly also
• • cold wash water and cold rinse water.

The given concrete example of the embodiment of the washing device 1 for the manual washing of beverage glasses represents a favorable and tested constructional arrangement, which is not binding. Other combinations of a construction solution are possible within the meaning of the claims.
