Description

BACKGROUND OF THE INVENTION The present invention relates to a dishwashing machine for hand-washing and rinsing beverage glass, in particular beer glasses with ears. The dishwasher consists of a dishwasher and a rinse unit. The washing vessel is equipped with mechanical brushes and optionally an effective cleaning chemical. The rinsing unit is equipped with a centrally located rinsing pin and side rinses. The washer is equipped with a supply of pressurized water to the washing vessel and rinse unit.

BACKGROUND OF THE INVENTION

A dishwasher of the owner SCHICKER & SCHAEFER GmbH, Wupertal DE, is known and protected by patent CZ 294 050, DE 299 10 353 of 1999, entitled "Device for cleaning and rinsing beverage containers !. The device consists of an open pre-rinsing pot with washing brushes and an arranged rinsing device with a perpendicular guide tube for water inlet. The rinsing device and the pre-rinse pot are connected by a common water supply and are attached to a pedestal formed as a hollow body within which a water rinse is provided. The water comes from the pre-rinse pot and is discharged from above into the rinse pot with brushes, from where it is discharged through the side outlet. It is essential to provide a plastic base which is sealed in a waterproof manner and has a sealed opening on the connection socket for attaching the water hose for one common water supply. The connection socket is designed as a closure cap and is sealed with an annular seal both on the threaded socket and in the through hole of the base out. The flushing vessel, and possibly the washing vessel, can be designed as substantially cylindrical vessels open at the top. The advantage of this solution is that the watertight sealed pedestal is encapsulated against any contact with water and has an outside connection to the water hose. The advantage and disadvantage of this solution may be that the waterproof closed base is mounted and the waterproof cap is sealed and encapsulated directly at the manufacturer.

A dishwasher and a dishwasher container of the owner DUNET s.r.o., Prague, CZ are known and protected by an industrial design CZ 32325, DE 359 07 269 from 2004. This dishwasher has one common base formed as a tray-shaped body with an open upper part. The pedestal slides freely to the bottom and the adjacent side walls of the two cylindrical containers constitute a wash and rinse container. The two containers are separated from each other by a common interface wall. Each container, both washing and rinsing, is provided in the vicinity of the common interface wall with two outlets, the upper part of which is open and substantially extends to the upper edge of the containers. Each bulge is closed at the bottom, and its height is substantially the same as that of the container. One of the bulges serves to hold the cup's ear. In the second outlet, when assembling the dishwasher, a hanging perforated tray is suspended above and / or immediately below the surface of the running water, into which a chemical cleaning tablet is placed to aid in the cleaning of the glass in cold water. The spouts can also serve for water drainage. In the rinse container, the central rinse tube is a nipple for rinsing the glass. In the common pedestal there is one through hole connected to the screw connection without a special seal for the connection socket to attach the hose for one common water supply. The water outlet from the wash container is formed by a pipe coming out of the wash container and guided through the hollow pedestal and outwardly loose and free, so that the opening at the bottom of the pedestal is not sealed in any way. The base is provided with mounting holes with screw connections and nuts of such a size that the base can be easily disassembled by hand without any tools, at any time and repeatable. Thus, the interior of the tray base is easily removable from both containers for cleaning, which is normally done by the operator in normal operation. The outflow from the rinse container is designed in a similar way to that of a wash vessel, i. The rinse water flows out through a pipe located at the bottom of the rinse container.

These hand-held glass washers are designed in such a way that they are usually inserted into a conventional sink with running water, in many cases with a limited space. All these dishwashers comprise a rinse unit of various types, also one whose side rinse units, e.g. in the form of fins, needles, and the like, are usually two and are situated opposite each other. However, they are firmly and immovably attached to the bottom of the rinse receptacle or rinse device or to the base, and thus no manipulation is possible during operation.

In Czech patent no. 296 462 and the corresponding published international patent application PCT / CZ2005 / 000090 disclose another improved dishwasher of the owner of DUNET s.r.o., Prague, CZ. This manufactured dishwasher has a rinse unit whose side rinses are reversible and adjustable rotatable relative to the spool. The side rinses are mounted on top of the annular base, loosely supported on the pedestal. The annular base has a central opening which is connected, on the one hand, to the inner space of the rinsing spout resulting in the main washer and, on the other hand, to the lateral ducts extending through the lateral opening to the inner ducts leading to the sidewash spray nozzles. The side rinses are formed from the outer part and the inner part facing the rinsing mandrel and provided with a side spray. Both these parts are detachably connected. The outer surface of the wash container and rinse unit or suitable components thereof is provided with a protective coating, preferably elastic. This dishwasher has both a wash bowl and a rinse unit both arranged on a single hollow pedestal in which a hollow holder is located and with one common supply of pressurized water to the wash vessel and the rinse unit. The rinse water flows out of the rinse tank through a pipe located above the bottom, the rinse water flows from the rinse unit through the internal cavity of the rinse unit rinse unit.

An advantage of the present invention is the easy and safe handling of the dishwasher and the side rinse washer in the event of a lack of working place or even saving the working place. During the working process, the operator can rotate the side washes with side washers to the desired angle and position for easier and safer access for the operator to insert the cup into the rinse unit. In addition, this solution according to the invention makes it possible to reduce the size and weight of the rinsing device by means of a simple design and thus also to reduce the dimensions and weight of the whole dishwasher.

All types of handwashers have one common disadvantage. So far only cold water is used for washing and rinsing the glass. Although washing of glass with cold pressurized water is also enhanced by mechanical cleaning with a central brush and peripheral brushes, as well as with a chemical dissolved in cold washing water, it may still be that such washing may not completely remove all impurities and grease from the glass surface. As for the subsequent rinsing of the glass with cold pressurized water, it loses its effectiveness if the washing is imperfect.

SUMMARY OF THE INVENTION

The above-mentioned disadvantages are eliminated or substantially reduced by a dishwasher for manually washing and rinsing beverage glass, in particular beer glasses with ear, or tea cups with raspberries, according to the invention, which consists in that the washing container and rinsing unit each have their own direct inlet for cold or hot water; each of these inlets is directly connected to its own cold or hot water supply. The lukewarm to warm water preferably has a temperature in the range of 25 to 50 ° C, preferably 35 to 40 ° C.

The wash vessel may have its own cold or hot wash water inlet connected directly through the wash valve head to its own cold or hot wash water supply; and the rinse unit may have its own cold or hot rinse water inlet connected directly through the adjustable rinse valve head to its own cold or hot rinse water supply.

The wash bowl and rinse unit can be mounted on a common bracket that is provided with two through holes for adjustable valve heads. Each of these valve heads is connected at one end to its own respective cold or hot water inlet to the dishwasher. At the opposite end, each valve head is connected to its own respective cold or hot water supply.

The holder may be a solid cross-sectional structural member or may be hollow within. When the holder has a hollow cross-section, its internal hollow space is provided with a partition which separates the wash and rinse water distributions. Each distribution is connected to the respective supply of washing and rinsing water. Thus, in more detail: a washing vessel and a rinse unit are mounted on the hollow holder, the hollow holder having a through-opening for a washing valve head which is connected at one end to the wash water inlet and at the opposite end to the wash water outlet connected to the wash water inlet; furthermore, the hollow holder is provided with a through-hole for a rinse valve head which is connected at one end to the rinse water inlet of the rinse unit and at the opposite end to the rinse water distribution connected to the rinse water supply; wherein the wash water distribution is separated from the rinse water distribution by a partition in the hollow holder.

All parts and / or surfaces of the dishwasher that come into contact with warm washing and warm rinsing water are made of a material that is mechanically and heat resistant to long-term temperature, preferably up to 80 to 100 ° C. These parts are a washing vessel, a rinsing unit, internal mandrels, valve heads or their surfaces in contact with pressurized hot water.

Pressurized washing and rinsing water is supplied separately to the dishwasher, and the washing and rinsing water is cold or lukewarm to warm.

Cold or warm rinse water is supplied to the washing vessel and cold or warm rinse water is separately supplied to the rinse unit. The lukewarm to warm wash water or lukewarm to warm rinse water preferably has a temperature in the range of 25 to 50 ° C, preferably 35 to 40 ° C. Hot or hot water should be used as appropriate as is convenient to the operator.

In detail: the washing water is supplied to the washing vessel inlet regulated through the washing valve head from the washing water supply; the rinse water is supplied to the rinse unit inlet regulated through the rinse valve head from the rinse water supply.

Essentially, four variants of supplying lukewarm to hot or cold water to the wash bowl and the rinse unit of the dishwasher are possible.

The dishwasher can operate in mode

- warm wash water and warm rinse water;

-Heated wash water, cold rinse water;

- cold wash water and warm rinse water;

- cold wash water and cold rinse water.

The main advantage of the present invention is to improve washing and rinsing hygiene and to enhance the performance of the dishwasher by better degreasing and removing impurities from the glass surface through separate inlets and downstream inlets of washing cold or lukewarm to warm water, and cold or lukewarm to warm rinsing water. especially the use of hot water has a significant effect on both 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 and regulated via the valve heads. Particularly when using pressurized warm washing water or pressurized warm rinsing water, such separation is desirable. This warm wash water and warm rinse water mode is particularly suitable for heavily soiled drinking and beer glasses or tea drinking glasses. The warm wash water and cold rinse water modes are suitable for the normal regime in restaurants, especially for washing beer glasses where the hot glass was not suitable for chilled beer, which could thus lose foam. Cold wash water and warm rinse water mode is suitable for drinking glass for tea and raspberries. The cold wash water and cold rinse water modes are suitable eg. for additional washing and rinsing after very dirty glass washed in hot wash water and warm rinse water.

The inlets of the washing and rinsing head are always routed separately but directly through the respective valve head to the inlet of the washing or rinsing unit.

If the construction of the dishwasher does not contain a holder, which is e.g. replaced by a suitable pedestal construction, the use is suitable when the rinse unit needs to be placed at a distance from the washing unit. The wash bowl and rinse unit may be supported on a full or hollow cross-sectional support. Both types of brackets always have two through holes for valve heads.

The direct connection of the water inlets through the valve heads in the non-hollow support bracket is suitable in the case of a smaller working space, where it is expedient for the rinsing unit to be located in the immediate vicinity of the washing vessel. Hollow bracket with partition in the manifold is suitable for smaller dishwashers. Material resistant to long-term temperatures up to approx. 80 to 100 ° C is used for all parts and surfaces that come in long-term contact with hot pressurized water.

The use of pressurized hot water, of course, places higher demands than the dishwasher material itself and the surfaces that come into contact with the hot water, but also increase the energy demand as well as the dishwasher design and type itself compared to the existing state. It can be assumed that not every existing dishwasher design can withstand thermal and thermal stresses with pressurized hot water for an extended period of time. However, these increased demands bring about a significant improvement in the cleanliness of the washed and rinsed glass.

A-A in FIG. 2, for a hollow holder with a partition, and FIG. 5 shows a detail of a hollow holder with a partition.

DETAILED DESCRIPTION OF THE INVENTION

A handwashing machine 1 for hand-washing and rinsing beer glasses with a handle is shown in a particular exemplary embodiment in an axonometric view in FIG. 1 and a top view of FIG. 2, consists of a washing vessel 2 and a rinsing unit 3 situated adjacent thereto. The washing vessel 2 and the rinsing unit 3 are detachably mounted on a common hollow pedestal 4. The hollow pedestal 4 may be formed as a tub-shaped body with profiled side walls with an open top. the upper peripheral collar into which the washing container 2 is inserted with the play and without any sealing.

The washing container 2 has a cylindrical shape with two side bulges 5 extending into the outside of the washing container 2 and having a semicircular cross-sectional shape. The two oppositely oriented outlets 5 open up are of the same height as the body of the wash container 2 and the bottom adjoining the bottom of the wash container 2. One of the outlets 5 is intended to loosely accommodate the cup handle with a clearance to slightly rotate it. The lower part of one of the concavities 5 can serve for the discharge of pressurized water. A perforated tray 6 (Fig. 2) with a solid detergent may be suspended at the top of one of the concavities 5.

The washing vessel 2 and the rinse unit 3 are in section A-A of FIG. 2 as shown in partially disassembled parts of the dishwasher 1.

The washing vessel 2 is provided with mechanical brushes, one of which is located on a perpendicular centrally arranged washing mandrel 7 (Figs. 2, 3, 4) and the other belt brush is situated on the inner periphery of the housing of the washing vessel 2 (Figs. 3, 4).

The rinsing unit 3 consists of a perpendicular centrally arranged rinsing mandrel 8 with a main washer (not shown) and a rinsing unit 9 with a side washer 10.

It can be seen from Figure 3 that both valve heads 32, 33 are located on a fixed support bracket 17.

The washing vessel 2 is provided with an inlet 12 of lukewarm to warm drinking glass washing water, with warm water having a temperature preferably in the range of 25 to 45 ° C, preferably around 35 ° C.

The rinse unit 3 is provided with a cold rinse water inlet 13 for rinsing the drinking glass, with the water temperature normally discharged from the tap.

The warm wash water inlet 12 into the wash vessel 2 is connected to the wash water inlet 22 itself through the wash valve head 32.

The cold rinse hot water inlet 13 to the rinse unit 3 is connected to its own rinse water supply 23 via its own valve rinse head 33.

The two valve heads 32, 33 are attached to the holder 17 (FIG. 3), which is mounted largely in the hollow pedestal 4.

In FIG. 3, the washing vessel 2 and the rinsing unit 3 are unfolded, which are fastened to the support bracket 17 with a full profile. The wash water is supplied to the inlet 12 of the wash vessel 2 regulated via the wash valve head 32 from the wash water inlet 22. The rinse water is supplied to the inlet 13 of the rinse unit 3 regulated via the rinse valve head 33 from the rinse water inlet 23. In particular, warm washing water is supplied to the washing vessel 2 with a temperature preferably in the range of 25 to 45 ° C, preferably around 35 ° C, and the rinsing unit 3 is supplied with separately cold rinsing water. The wash vessel 2 has its own hot wash water inlet 12 connected directly through the wash valve head 32 to its own hot wash water inlet 22. The rinse unit 3 has its own cold rinse water inlet 13 connected directly through the rinse valve head 33 to its own cold rinse water supply 23. The wash vessel 2 and the rinse unit 3 are mounted on a common holder 17 provided with two through holes for the control valve heads 32, 33. The wash valve head 32 extends at one end to its own hot water inlet 12 into the wash vessel 2, and the opposite the end is at its own hot water supply 22. The rinse valve head 33 is connected at one end to its own cold water inlet 13 to the rinse unit 3, and at its opposite end is to its own cold water inlet 23.

In FIG. 4 shows an alternative embodiment of an unfolded wash bowl 2 and a rinse unit 3, which are mounted on a support bracket 17 which is hollow inside (FIG. 5) and is provided with a partition 15 which separates the wash and rinse water distributions 42 to the respective wash and rinse water inlets 22, 23. Thus, the wash bowl 2 and the rinse unit 3 are fastened to the hollow holder 17. The hollow holder 17 is provided with a through hole for the wash valve head 32 which is connected at one end to the hot wash water inlet 12 and the opposite end to the hot wash water distribution 42. connected to the hot wash water inlet 12. Further, the hollow holder 17 is provided with an additional through hole for the rinse valve head 33, which is connected at one end to the cold rinse water inlet 13 to the rinse unit 3 and at the opposite end to the cold rinse water distribution 43 connected to the cold rinse water inlet. The hot wash water distribution 42 is thus separated from the cold rinse water distribution 43 by a partition 15 in the hollow holder 17.

Dishwashers 1 according to the previous two exemplary embodiments operate as follows:

At the top end of the central brush wash sponge 7, the operator places the beer glass upside down by inserting one ear into one of the bulges 5. The operator presses from above with a slight pressure on the bottom of the beer cup on the wash sponge 7 (Figs. 1, 2). The needle of the scrub valve head 32 allows the scrubbing water to be introduced into the scrubber 7 and pressurized warm scrubbing water from below through the channel-like interior of the scrubber, which acts on the inner surface of the cup via the scrubber main. The brush on the washing sponge 7 helps to clean the inner surface of the cup (Figs. 3, 4). The hot water flows from the washing darkness 7 into the space of the washing container 2, and this hot water together with another circumferentially located belt brush (br. 3, 4) washes the outer surface of the glass mechanically. Washing efficiency in warm water can be enhanced by chemical detergents of various kinds, both liquid and solid. In the case of a solid state detergent, e.g. in particular, the tablet embedded in the hanging tray 6 (FIG. 2), upon contact of the warm wash bath, it slowly dissolves and acts. When the operator lifts the cup over the wash spike 7, the wash valve head needle 32 closes the wash water supply. The washing water used drains, e.g. an opening (not shown) at the bottom of the washing container 2 out into the sink.

The washed cup is inserted into the rinsing unit 3 so that the operator puts the glass upside down on the centrally arranged rinsing spigot 8. Subsequently, the operator exerts a slight pressure on the bottom of the glass on the rinsing spigot 8. The rinse valve head needle 33 releases the rinsing water water, on the one hand to the main washer rinsing pin 8 to rinse the inner surface of the cup, and also to both side rinses 9 with the side washer 10 to rinse the outer surface of the cup. When the operator removes the cup from rinsing darkness 8, the needle of the rinsing valve head 33 interrupts the rinse water supply. Used rinsing water drains eg. an opening (not shown) at the bottom of the rinsing unit 3 outwards, e.g. into sink.

This type of hand dish washer 1 is usually inserted into a sink. In this usually very confined space, the functional properties of the hand dishwasher 1 increase the possibility of reversible and adjustable rotation of the side rinses 9 of the rinsing unit 3, in particular for rinsing beer glasses with an ear. The operator can then place the beer cup with the handle on the central rinsing pin 8 where there is space and without having to turn the entire dishwasher 1.

The use of warm washing water for washing the glasses ensures a higher cleanliness and hygiene when washing glasses, especially beer glasses dry. The use of cold rinsing water for rinsing is particularly suitable for beer glasses during normal operation with the requirement that the beer foam does not drop in the overheated glass.

However, other alternative embodiments are also possible in which warm washing water is supplied to the washing vessel 2 and cold rinsing water is separately supplied to the rinsing unit 3.

Alternatively, washing cold water is supplied to the washing vessel 2 and warm rinsing water is separately supplied to the rinsing unit 3.

Optionally, cold water is supplied separately to the washing vessel 2 and the rinsing unit 3.

If the operator wants to change the cold water mode to hot and vice versa, connect eg. a water hose (not shown) to a hot or cold water source or battery.

Instead of the rinsing unit 3, it is possible to use a rinsing vessel similar in shape to the washing vessel 2 in FIG. 1 and 2, i.e. a cylindrical rinsing vessel from above open and with a central rinsing pin 8 and a side rinse disposed in the walls of the rinsing vessel.

All parts of the dishwasher 1 which come into contact with warm washing and rinsing water are made of a material resistant to long-term temperatures of up to about 80 to 100 ° C.

This particular embodiment of the dishwasher also for the manual washing of the drinking glass is a convenient and tested construction which is not exhaustive. Other combinations of design within the scope of the spirit of the claims are possible.

Industrial usability

The solution is suitable for restaurants and gastronomic operations for manual washing of hollow glass, porcelain and possibly ceramics.
