Prior art

A dishwasher owned by SCHICKER & SCHAEFER GmbH, Wupertal DE, protected by patent CZ 294050, DE 29910353 from 1999, entitled Equipment for cleaning and rinsing beverage containers, is known and manufactured. The device consists of an open pre-rinsing pot with washing brushes and a rinsing device arranged next to it with a vertical guide tube for the inflow of water. The rinsing device and the pre-rinsing pot are connected by one common water supply and are mounted on a base formed as a hollow body, in the interior of which there is a water supply for pre-rinsing. The water passes through a pre-rinsing pot and from above it is drained from it to a rinsing pot with brushes, from where it is drained by a side outlet. It is essential to form a base made of plastic, which is watertight and contains a sealed opening for a connection socket for attaching a water hose and a common water supply. The connection socket is designed as a closing cap and is sealed with an O-ring, both on the threaded socket and in the through hole of the base on the outside. The flushing vessel or the washing vessel can be designed as a substantially cylindrical vessel open at the top. The advantage of this solution is that the watertight closed base is encapsulated against any contact with water and contains an externally accessible connection socket for the water hose. The advantage and disadvantage of this solution may be that the watertight sealed base is mounted, watertightly closed and encapsulated directly at the manufacturer.

The dishwasher and dishwasher containers of the owner DUNĚT s.r.o., CZ are protected and manufactured, protected, inter alia, by the industrial design CZ 32325 and the corresponding DE 35907269 from 2004. This dishwasher has a common base. Both washing and rinsing containers are separated from each other by a common contact wall. This basic design of the DUNĚT dishwasher with important basic technical features is still used today.

The owner DUNĚT s.r.o., CZ, also had the individual components of the dishwasher protected by industrial designs: CZ 30579 and DE 40407269 for the shape of the washing and rinsing container; CZ 31668 and DE 40305308 for dishwasher holder; CZ 31567 and DE 40304788 for a hanging tray for a tablet in a washing container; and CZ 31562 and DE 40304787 for cleaning and disinfecting tablets.

CZ 296462 B6 and the corresponding WO 2007/038904 A1 describe another improved dishwasher of the owner DUNĚT s.r.o., Prague, CZ. This manufactured dishwasher has a rinsing unit, the side rinses of which are reversibly and adjustably rotatably movable relative to the rinsing darkness. The side rinses are mounted on top of an annular base, loosely mounted on a pedestal. The annular base has a central opening which is connected on the one hand to the inner space of the rinsing darkness leading to the main spray and on the other hand to the side channels adjoining through the side opening to the inner channels leading to the side rinsing nozzles of the side rinses. The side rinses are formed of an outer part and an inner part facing the rinsing darkness and provided with a side spray. The two parts are detachably connected to each other. The outer surface of the washing vessel and the rinsing unit, or suitable components thereof, is provided with a protective coating, preferably elastic. This dishwasher has a washing vessel and a rinsing unit arranged on one hollow base,

- 1 CZ 34918 UI in which a hollow support bracket is placed and with one common supply of pressurized water to the washing vessel and the rinsing unit. The washing water drains from the washing vessel through a pipe located above the bottom, the rinsing water flows out of the rinsing unit through the inner cavity of the rinsing darkness of the rinsing unit.

The advantage of this technical solution is easy and safe handling of the operator with the dishwasher and with the spraying of side rinses in case of lack of work space or even saving work space. During the work process, the operator can rotate the side rinsing side rinses to the desired angle and position, allowing easier and safer operator access to insert the glass into the rinsing unit. In addition, this solution enables a reduction in the size of the rinsing device and its weight, and thus also a reduction in the dimensions and weight of the entire dishwasher, by a simple design modification.

All these types of hand dishwashers have one common disadvantage. So far, only cold water is used for washing and subsequent rinsing of the glass. Although washing the glass with cold pressurized water is also intensified by mechanical cleaning with a central brush and circumferential brushes and also by a chemical dissolved in cold washing water, even such washing may not completely remove all dirt 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.

CZ 298756 B6 and the corresponding DE 102007051100 owned by DUNĚT s.r.o., CZ, describes a glass washer solution for manual washing and rinsing of drinking glasses, especially beer glasses with an ear with the possible use of cold or even hot water. The washing tank and the rinsing unit each have their own separate direct inlet for either cold or hot water. Each of these inlets is connected to a supply for either cold and / or hot water and is separated by a partition in the support bracket. A washing container and a rinsing unit are mounted on this support bracket. The holder here is an important load-bearing component of the entire dishwasher. The hollow holder is equipped with a vertical partition, which separates the distribution of washing and rinsing water.

This partitioned solution is relatively difficult to manufacture at high investment costs and also difficult for the operator. In addition, during field tests and in practice, it turned out that this type of support bracket and the vertical partition in the middle, separating the water distribution, are the weakest element of the dishwasher. The partition of the holder is mechanically and thermally stressed and dirt settles in its corners. Therefore, this dishwasher did not expand, i.e. the intended use of hot water in the dishwasher lines for at least one washing or rinsing vessel.

Basically, the disadvantage of these existing dishwashers is only one real water supply, namely. either only cold or only hot water for washing and rinsing.

The aim of this technical solution was to achieve a safe design separation of two water circuits in the existing dishwashers, washing and rinsing, with the possibility of using lukewarm to warm water.

The essence of the technical solution

Said disadvantages are eliminated or substantially reduced by a dishwasher for hand washing and rinsing of drinking glasses, in particular and beer glasses with a handle, or glasses with a handle for tea and lemonades according to this technical solution. The dishwasher comprises two basic components, a washing vessel and a rinsing vessel or rinsing unit. The washing container is equipped with mechanical brushes, or it is equipped with a hanging tray with an effective cleaning chemical and equipped with a washing mandrel. The rinsing vessel or rinsing unit is equipped with a central rinsing mandrel and side sprays. The dishwasher has a water supply to the washing vessel and the rinsing vessel or rinsing unit, a common base and adjustable valve heads.

The essence of this technical solution lies in the fact that the hand dishwasher has a separate washing and rinsing circuit. Each valve head, washing head and rinsing head, has its water distribution continuously connected to the water distribution of a hollow connecting means, connected to a separate separate inlet

- 2 CZ 34918 UI of water for creating a separate separate washing circuit for washing the drinking glass in the washing vessel and for creating a separate rinsing circuit for rinsing the drinking glass in the rinsing vessel or rinsing unit, the pressure washing or rinsing water being either cold or hot in the range of 25 to 50 ° C, or lukewarm water in the range of 35 to 40 ° C. The washing vessel thus has its direct inlet of washing pressurized water from a controllable washing valve head, which is connected at the opposite end to a direct inlet of washing pressurized water. And the rinsing vessel or rinsing unit has its direct washing pressure water inlet from a controllable rinsing valve head, which is connected at the opposite end to a direct rinsing water supply. Overall, the valve head was designed specifically for the purposes of the dishwasher according to this technical solution

The connecting means may be a hollow tube directly connected to the valve head and connected at the opposite end to the water supply. The connecting means may be an outer hollow protrusion of the valve head connected to a hollow connecting element connected to the water supply. The hollow protrusion on the valve head body can advantageously be integrally connected to the hollow connecting element in one unit. The hollow connecting element is preferably an elbow or a hollow tube. In the case of an elbow, for example, the hollow protrusion on the valve head body is arranged horizontally and is connected to a horizontal part of a rectangular elbow, the vertical part of which faces downwards and is connected to a water supply.

It is advantageous if each valve head has a body provided with an external central thread for fixing a 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 closure lid made of rigid plastic with a metal nut arranged in the middle.

It is further preferred that each valve head has a body at the upper edge provided with an upper thread for a cover nut for fixing the valve head to the washing vessel and the rinsing vessel or rinsing unit.

The washing vessel and the rinsing vessel or rinsing unit are housed in a common tub-shaped base, the bottom of which is provided with flat bulges projecting above the bottom on the side facing the washing vessel and the rinsing vessel or rinsing unit.

The bulge located below the washing vessel and the rinsing vessel is provided with two through holes for the supply of washing water; two holes for fixing the washing valve head in the base, these holes being covered outside the base of the base by spacer screws; and four supports for stabilizing the washing valve head in the base.

The bulge located under the washing vessel and the rinsing unit is provided with two through holes for the supply of rinsing water; two holes for fixing the washing valve head, these holes being covered outside the bottom of the base by spacer screws; and three supports for stabilizing the washing valve head in the base.

The bottom of the base tray under the washing vessel and the rinsing vessel is provided with two openings for the outflow of washing and rinsing water; and the bottom of the base tray under the washing vessel and the rinsing unit is provided with one opening for the outflow of washing and rinsing water.

The base is equipped with four suction cups on the outside when attaching the dishwasher to the base.

The main advantages of the dishwasher according to this technical solution are separate washing and rinsing water circuits, which allow the use of cold and hot water for the dishwasher at the same time, improve hygiene during washing and subsequent rinsing and increase dishwasher performance by better degreasing and removing impurities from the glass surface by separate inlets, and adjoining cold or lukewarm to warm water washers, and cold or lukewarm to warm rinsing water inlets. In particular, the use of hot water has a significant effect on the cleanliness and speed of washing. Washing water for washing in a washing vessel and rinsing

- 3 CZ 34918 UI rinsing water in the rinsing unit is supplied to each other separately and in a controlled manner via separate adjustable valve heads, washing and rinsing. Especially when using pressurized hot wash water or pressurized hot rinse water, such separation is desirable. This mode of warm washing water and warm rinsing water is especially suitable for heavily soiled drinking beer glass, drinking glass for tea, coffee or lemonade. The "warm wash water and cold rinse water" mode is suitable for the normal mode in restaurants, especially for washing beer glasses, where the hot glass would not be suitable for chilled beer, which could lose foam. The "cold wash water and warm rinse water" mode is suitable for drinking glasses for tea and lemonades. The cold wash and cold rinse water mode is suitable, eg for additional washing and rinsing of heavily soiled glass, washed in the "warm wash and warm rinse water" mode.

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

The use of pressurized hot water, of course, places higher demands both on the material of the dishwasher itself and on its surfaces that come into contact with the hot water. The material of the dishwasher resistant to long-term temperatures up to approx. 80 to 100 ° C was used for all parts and surfaces that come into long-term contact with hot pressurized water.

Applicant DUNĚT s.r.o. dishwashers according to this technical solution is constantly working on the development of its dishwashers for washing and rinsing glass. The dishwasher according to this technical solution was also developed on the basis of the customer's request for washing and rinsing with warm water, especially in epidemiologically demanding times. For most existing dishwashers owned by DUNĚT s.r.o. The dishwashers have a support bracket that carries at its ends a washing and rinsing valve head and is equipped with only one common water supply for washing and rinsing. In addition, this holder is an important supporting element of the existing dishwashers of DUNĚT s.r.o. The new dishwasher according to this technical solution has a design change, which represents an absolutely fundamental breakthrough in the design of the new dishwasher, which is lightweight, allows safe and tested separation of washing and rinsing water, with targeted use of safely separated hot and cold water circuits. This is made possible by the construction of a new type of valve heads for a new type of dishwasher and a modified dishwasher base. Existing types of washing tank and rinsing tank or rinsing unit are unchanged.

A great advantage of the non-electric hand dishwasher according to the technical solution, most of whose components are made of hard plastic, is that it can be disassembled repeatedly without hand tools, which allows washing 90% of the components of this non-electric hand dishwasher in a conventional electric dishwasher.

Another great advantage of the dishwasher according to the technical solution is the manual and intuitive disassembly of the basic parts of the dishwasher even in a new arrangement, without any tools. E.g. The washing container, which is especially subject to contamination, can be removed from the base. The central brush or the circumferential brush can also be easily removed from the washing bowl. All these parts of the washing vessel can be placed in a conventional electric dishwasher; and the more often this maintenance of the washing vessel is performed, e.g. daily or even several times a day, the longer the life of the dishwasher is extended. The rinsing container or the rinsing unit can also be removed from the base. Their central spray with side rinses is also removable. However, these parts of the rinse do not need to be cleaned as often. For occasional cleaning, it is recommended to clean the base and the operator can do this during normal operation if necessary. The base is provided at its bottom with mounting holes with screw connections and nuts of such a size that the base can be easily and repeatedly disassembled by hand and without any tools at any time as needed. The tray-shaped base is therefore easily removable from both the containers, the washing container and the rinsing container or the rinsing unit.

The disassembly of the dishwasher according to this technical solution has other advantages. In the event of a malfunction of a dishwasher component, this component can be easily replaced and there is no need to buy a whole new dishwasher. If the customer has older types of dishwasher DUNĚT s.r.o., and wants a new type of dishwasher according to this technical solution, he can use a washing vessel, rinsing vessel or rinsing unit from the older type of dishwasher, and only buy new valve heads and a new base.

The dishwasher 1 for hand washing and rinsing of drinking glasses, in particular beer glasses (not shown) with a handle, is shown in a specific exemplary embodiment in an axonometric view in Fig. 1 and in a top view in Fig. 2. The dishwasher 1 consists of a washing vessel 2 and situated next to it rinsing containers 3. Both containers 1,2 have a cylindrical shape and are separated from each other by a common contact wall. A washing container 2 and a rinsing container 3 of the owner DUNĚT s.r.o., CZ are used, protected, inter alia, by the industrial design CZ 32325 and the corresponding DE 35907269 from 2004.

The washing container 2 and the rinsing container 3 are removably mounted on a common hollow base 4. The hollow base 4 can be formed as a tub-shaped body with profiled side walls with an open upper part and an upper circumferential collar into which it is slid loosely and without any seal. , both the washing vessel 2 and the rinsing vessel 3.

The washing container 2 has a cylindrical shape. The washing vessel 2 is provided near the contact wall with two side bulges 5 along the entire height of the washing vessel 2. The bulges 5 protrude outside the washing vessel 2 and have a semicircular shape in cross section. Both vertical oppositely oriented bulges 5 have the same height as the body of the washing container 2. The bulges 5 are open at the top and have a bottom adjoining the bottom of the washing container 2. One of the bulges 5 is intended for free storage of the glass handle with clearance for slight rotation. The lower part of one of the bulges 5 can serve for the overflow 51 and the discharge of pressurized water. A perforated tray 6 can be hung on the upper circumference of the washing vessel 2, outside the circumferential washing brush 14b, anywhere outside the bulge 5, as shown in Fig. 2. The tray 6 is hung above or immediately below the surface of running water. A solid detergent in the form of, for example, a tablet can be stored in the tray 6 to facilitate washing and dry cleaning of the drinking glass.

The washing container 2 is provided with a mechanical brush 14a. 14b. as can be seen in the left part of Fig. 2. The central mechanical brush 14a is placed on a perpendicular centrally arranged washing dark 7 and the second belt circumferentially arranged mechanical brush 14b is attached to the inner circumferential grooves 2b of the washing container 2.

Figure 3a shows an adjustable washing valve head 32 with its own pressure washing water inlet 12 in the washing vessel 2 and with its own washing water inlet 22 to the washing valve. of the head 32. The washing water inlet 12 and the washing water inlet 22 are connected by a washing water distribution 42. Fig. 3b shows an adjustable rinsing valve head 33 with its own pressurized rinsing water inlet 13 to the rinsing vessel 3 and with its own rinsing water supply 23 to the rinsing valve head 33. The rinsing water inlet 13 and the rinsing water supply 23 are connected by a rinsing water distribution 43. In FIGS. 3a and 3b, the two valve heads 32, 33 are situated opposite one another with their water inlets 22, 23, as they are arranged in the dishwasher 1. In fact, the two valve heads 32, 33 are structurally identical.

One of the bulges 5 in the washing vessel 2, in which the overflow 51 of the water is placed, can serve to drain the water from the washing vessel 2. The water outlet from the washing vessel 2 can be formed by a drain pipe (not shown) emerging from the washing vessel 2 and led out of it through the hollow base 4 freely and loosely, so that the water outlet opening 24 at the bottom of the base 4 is not sealed in normal operation. The outflow from the rinsing unit 3 is solved in such a way that the rinsing water flows through a drain pipe 31 located in the lower part of the rinsing vessel 3. The outflow of washing and rinsing water through one opening 24 in the bottom of the base 4 is aided by the base 4 in the shape of a tray with a relatively high circumferential collar. in which water collects.

In the axonometric view of Fig. 4, the dishwasher is shown in a disassembled state. The upper part shows an axonometric view of a washing vessel 2 with a vertical axis 2a and a rinsing vessel 3 with a vertical axis 3a, under which both identical and oppositely oriented valve heads 32, 33 are situated in the dishwasher 1.

The lower part of the valve head 32, 33 is closed by a lid 19.

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

Another new advantageous element is a softened plastic seal 18, which seals and at the same time evens out the space between the surface of the washing container 2 or the rinsing container 3 and the base 4.

Dishwasher 1 works as follows:

The hand dishwasher 1 according to this technical solution is normally inserted into a washing sink with running water. In this usually very cramped space, the functional properties of the hand dishwasher 1 are increased by 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 glass with the handle on the central rinsing tm 8 where it is right, without having to turn the whole dishwasher 1 without difficulty.

The wash water circuit and the rinse water circuit are separate and separate. The washing water circuit comprises a pressurized washing water inlet 22 and a washing water inlet 12 to the washing vessel 2 via an adjustable washing valve head 32. Washing water is supplied from the inlet 22 to the interior of the valve head manifold 42 via an elbow 16 and through a manifold 42 to a separate inlet. 12 of the washing valve head 32 and subsequently to the washing vessel 2. The rinsing water circuit comprises a pressurized rinsing water inlet 23 and a rinsing water inlet 13 to the rinsing vessel 3 via an adjustable rinsing valve head 33. The rinsing water is supplied from the water inlet 23 to the interior of the manifold 43 the rinsing valve heads 33 through the elbow 16 and the manifold 43 are led to a separate inlet 13 of the rinsing valve head 33 into the rinsing vessel 3. The two separate valve heads 32, 33 are housed in a common base 4.

Washing in the washing container 2 takes place in such a way that the operator places a beer glass (not shown upside down) on the upper end of the washing dark 7 with a central washing brush 14a by inserting one ear into one of the bulges 5. The operator presses the bottom of the beer glass with slight pressure from above. on washing darkness 7 (Figs. 1, 2). As a result, pressurized water begins to enter the washing dark 7 through its channel-shaped inner space from below, which pressurizes the inner surface of the glass by means of a central spray 8a of the washing dark 7. The washing of the inner surface of the glass is mechanically assisted by a brush 14a on the washing machine

-8EN 34918 UI of the darkness 7. Water flows from the washing darkness 7 into the space of the washing vessel 2 and this water, together with another circumferentially located belt brush 14b, mechanically washes the outer surface of the glass. The effectiveness of washing in cold water and hot water is increased by chemicals - detergents of various types, both liquid and solid. In the case of a solid detergent, e.g. in particular, the tablets inserted in the hanging tray 6 (Fig. 2), when they come into contact with the washing bath, it gradually dissolves and acts.

This is followed by rinsing in the rinsing vessel 3. The washed glass is placed in the rinsing vessel 3 in such a way that the operator places the beer glass on the centrally arranged rinsing tank 8 upside down. Subsequently, the operator exerts a slight pressure on the bottom of the glass on the rinsing dark 8. This initiates the inflow of pressurized water into the rinsing dark 8 with a central spray 8a to rinse the inner surface of the glass and into both side rinses 9 with a side spray 10 to rinse the outer surface of the glass. .

As far as the arrangement of the valve heads 32, 33 is concerned, both have the same construction, the same applies to them as stated in the previous exemplary embodiment with reference to Fig. 13, in which the individual parts of the valve heads 32, 33 are shown; Fig. 14 is a front view of the valve head 32, 33; and its vertical section is shown in Fig. 15

Dishwasher 1 works as follows:

Washing of drinking glasses, especially beer glasses, proceeds in the same way as in the previous Example 1.

This is followed by rinsing in the rinsing unit 30. The washed glass is inserted into the rinsing unit 30 so that the operator places the beer glass on the centrally arranged rinsing unit 8 with the bottom facing upwards. Subsequently, the operator exerts a slight pressure on the bottom of the glass on the rinsing dark 8. This initiates the inflow of pressurized water into the rinsing dark 8 with a central spray 8a to rinse the inner surface of the glass and into both side rinses 9 with a side spray 10 to rinse the outer surface of the glass. .

The arrangement of the rinsing unit 30 according to this technical solution is different. The rinsing unit 30 according to this technical solution has a central rinsing unit 8 and two oppositely situated side rinses 9 are arranged perpendicularly on the plate-shaped annular base 11 (Figs. 7, 8). The rinsing unit 3 is placed in the collar of the tray body 4 of the base 4 in such a way that an annular base 11 with a central opening through which the rinsing darkness 8 passes is placed loosely on it, the annular base 11 with both fixed side rinsings 9 being loosely mounted and freely rotatable. on the upper part of the hollow base 4, to which it is pressed by the central rinsing dark 8 with a central spray 8a. When the annular base 11 is rotated, the central rinsing darkness 8 remains in place and the two side rinses 9 with side sprays 10 are picked up with the annular base 11. This rotation of the annular base 11 with both side rinses 9 ("fins") can be made by the operator. The operator can thus easily readjust and rotate both side rinses 9 from the original position as required.
