Description

The invention relates to a cleaning device of repeatedly usable tools, in particular knife and cutting tools in confectioneries, cheese shops, butchers and the like, with a container into which a Cleaning fluid is fillable, with to be arranged in the container Brush device and one above the liquid level the cleaning liquid lying scraper.

For the cleaning example of knives are so far in many grocers knife quivers in use, which require cleaning and their cleaning fluid must be changed frequently, especially at times of High activity and often lack of cleaning equipment is neglected. In addition, the cleaning of a tool takes or knife in such quivers because of immersion, optionally subsequent stirring etc. or only subsequent wiping - usually on a cloth, Apron, sponge - relatively long. Mostly they are Knife due to handling errors, dirty cloths and dirty cleaning fluids after the cleaning process Afflicted with a variety of microorganisms, ie hygienic not enough clean and above all not dry. Observations in factories, such knife quivers insert, that also there the cleaning of the Knife is faulty or not performed at all.

From DE 42 06 349 A1 discloses a cleaning device for Color bar or similar tools known, the already a brush device below a liquid level in which the color bar by a small opening is insertable. Next is a second, not provided with liquid chamber in the Color-dipsticks can be put down after cleaning so that they dry out there. Because of the slow drying is this known cleaning device for fast cleaning processes of dry tools when cleaned not suitable.

From DE 37 13 899 A1 discloses a cleaning device for Cleaning of medical hand instruments and hand tools known for hair, skin or body treatment.

In this known device are to splatter of cleaning fluid when brushing the tools too Also avoid brushing below the liquid level appropriate. For the same purpose is the cleaning tank also closed with a lid. This does too the known device becomes unwieldy in its daily use, because the tools through a narrow opening in the Cleaning fluid must be dipped. The well-known Cleaning device is only for pre-cleaning tools designed before a subsequent disinfection, so that a drying of the handsets is not provided.

DE 196 39 019 C2 already discloses a device for Cleaning of repeatedly used tools, in particular Cutting tools with a container for better handling and faster execution of the cleaning process is filled with cleaning fluid, such that the container receiving the cleaning fluid at least a arranged below the liquid level Brush device and at least one above the liquid level having arranged scraper.

The entire cleaning device consists of numerous Items removed individually to clean the device and have to be cleaned. In addition, looks this cleaning device does not clean the tool in the transition area to the handle approach.

The invention is therefore based on the object, a cleaning device to create, on the one hand, the simple and fast, hygienically improved cleaning of tools like knives and cutters in cheese shops, pastry shops and the like, and on the other hand from the Operator of the device easily handled and cleaned or can be maintained.

The object is achieved in that the Brush device and the stripping device on a drain pipe indirectly or directly attached, the detachable and liquid-tight in a drain opening of the container used is.

The device according to the invention thus has the essential Advantage that the cleaning device after use particularly easy to clean. The drain pipe is pulled out of the container and with the drain pipe all the facilities for cleaning the tools taken out of the container. The drain pipe with brush and Scraper device (cleaning unit) can be used in a dishwasher getting cleaned. If you remove the drain pipe from the container, This is how the dirty cleaning fluid overflows the outlet opening completely out of the container. The container interior surfaces can be easily cleaned by hand, because no attachments are provided on these surfaces, or via an intensified flushing with fresh water, preferably heated, the container interior can be especially in the bottom area and on the adjacent side surfaces effectively clean and rinse by adding a stronger cleaning fluid inflow into the container over a given Period allows. The drainpipe is in this cleaning process removed, so that after a damming of reinforced inflowing cleaning liquid this immediately drains through the drain opening in the container and dirt at the container inner walls and deposits entrains on the tank bottom.

Is the cleaning unit, consisting of at least the drain pipe, the brushing and scraping device, soiled, Defective or worn, it can be easily handled in a few seconds through another new, clean cleaning unit be replaced.

The cleaning liquid is predominantly heated water, directly into the container via the liquid feed opening can flow in. Alternatively, the cleaning fluid exclusively or additionally in the container be heated to a desired temperature.

Through the continuous withdrawal of cleaning fluid From the tank via the drainpipe creates a laminar Flow of cleaning fluid in the tank discharged from the Liquid inlet is directed to the liquid flow, i.e., dirt particles, emulsions, generally impurities resulting from the cleaning of tools are due the constantly maintained flow from the liquid inlet transported to the liquid drain and there removed from the container. This transport process is supported nor by temperature differences produced in the container or by the warm or in the container heated cleaning liquid. If the cleaning fluid is still additional heated in the container, the result is a temperature gradient in the container. The temperature of the cleaning fluid Increases constantly to the liquid flow out. Through this thermal temperature increase forms an additional driving force to the liquid outlet out and breaks or drives impurities in the cleaning fluid in the fluid outlet. At the same time arises through this driving gradient from liquid inlet to liquid outlet a self-cleaning effect in the cleaning device one. The degree of self-cleaning can be by the liquid exchange rate to be set by the operator to adjust. The self-cleaning effect in the container is then greatest when laminar flow is a constant Circulation of the cleaning liquid in the container takes place and simultaneously at least the per unit time supplied Cleaning liquid also on the liquid drain again is dissipated.

In a further preferred embodiment of the invention are to the drainpipe retaining strips provided for releasable Recording of the brush device and the stripping device are suitable.

This has the advantage that brush or wiper lips easy and safe in the retaining strips, preferably in one Level opposite, can be fixed. The brush or wiper lips made of rubber or rubber-like Plastic can be after a natural wear, the through numerous cleaning processes of tools or a Defect arises, simply swap it by adding new ones Brush strips or new wiper strips in the retaining strips which holds the brushes and scrapers. The Brush strips or scraper strips are so in the Retaining strips inserted that the free ends of themselves Touch opposite brush threads, overlap or are slightly spaced from each other. Side surfaces of the Soiled tools, such as knives, are moved through the open space pulled between the opposite brush threads or the brush threads become during a cleaning movement with the tool to be cleaned from the to be cleaned The tool part up or bent over so that they move during tool movement close to the sections of the tool to be cleaned abut these areas of contamination too clean and / or dry.

In a further embodiment of the invention is the drain pipe lying above the liquid level of the cleaning liquid provided an injection device, which also on the holding block can be attached.

This has the advantage that, for example, by the brushes Cleaned blades in the cleaning fluid, blade surfaces above the liquid level of the cleaning liquid additionally with cold or warm fresh water or can be sprayed with steam before the cleaned ones Knife surfaces if necessary by means of the stripping be dried. Disinfection or sterilization the cleaned tool surfaces is possible. In the Wiper device is wiper lips a rubber or plastic-like band material, the pointed at the free end and at the opposite side, Stiffening axially extending end or edge so that it can be pushed into the retaining strips can. Two wiper lips lie in a horizontal Level, touching or overlapping, so a tool pulled through the wiper reliably dried by the tapered lip rims becomes.

Preferably, the drain pipe ends in an at least partially above the liquid level of the cleaning liquid Holding block in which an open end of the drainpipe is fixed, and the holding block has a through hole to the open end of the drain pipe. This has the Advantage that the handling of the drainpipe for the operator is simplified by removing the drainpipe from the cleaning liquid not in the cleaning liquid and it is also possible to the brush device, the stripping device as well as the To attach spraying device to the holding block. The holding block is designed so that it is guided centrally in the Container is inserted and there centric aligned is held.

In a further embodiment of the invention, the holding block laterally acting clamping means for releasably fixing the Holding block in the container.

This has the advantage that the inserted into the container Holding block or the cleaning unit stably fixed in the container can be. The clamping means may be clamping bolts, the via a rotatable handle on the holding block outside the Cleaning fluid can be activated by the Grip twisted and the clamping bolts from the side surfaces of the holding block pushes out until it on the Press the inner surface of the container so hard that the Holding block is held immovably in the container. Thus are also attached to the holding block, in the cleaning liquid lying devices immovably in the cleaning fluid arranged and the cleaning unit can become due to a generated with the tool to be cleaned Pressing or a pulling movement in the cleaning liquid do not move.

It is also advantageous if on the width of the holding block matched to the inner wall of the container guide rails, in particular beads, are provided. These have the Advantage that the holding block with the cleaning unit is guided in the container can be inserted and the free end of the Drain pipe sealing and accurate in the drain opening of the container can be used. In addition, the Side wall of the container still stiffened, leaving an over the clamping means of the holding block generated pressure on the Behätlerinnenwandungen do not cause damage to the container can. The beads extend in a vertical direction to the corresponding inner walls of the container.

It is particularly advantageous if of several brushes Brush device, at least one pair of brushes for free At the end it opens conically and is largely over the entire Opening of the container extends. In such a pair of brushes a tool to be cleaned can be easily introduced and due to the large opening or spacing of the Coarse dirt can be applied to opposing brushes Especially easy to strip on these brush sections. In axial extension of this conically opening Brush pair takes the spacing of the free ends the opposing brush threads steadily until until Touch the brush threads from opposite brushes. The tool to be cleaned is in the brush assembly guided, directly below the stripping device or Spraying device is arranged. Once that to be cleaned Tool pushed into the area of the wiper or is guided, the tool with the in the cleaning fluid lying surface sections through the stripping be pulled out of the container. at In this movement, the surface sections below the Liquid level of the cleaning liquid again from the brushes arranged there cleaned and above the Liquid level of the cleaning liquid are the cleaned surfaces either again with a fresh water or steam additionally cleaned or treated before they then dried from the lips of the stripper be by the still adhering liquid of the cleaned surfaces is deducted.

In a preferred embodiment of the invention that is immediate arranged under the liquid level brush pair at least partially seen over its axial extent, attached obliquely aligned to the liquid level.

This has the advantage that also a particularly intense Cleaning takes place at the transition of a handle to a tool. The transition from a knife blade to the handle attachment is thus particularly intensively cleaned.

The retaining strips are preferably designed as clamping sleeves, which have an open groove along their axial extent. This constructive training ensures on the one hand, that new brush strips or squeegee in the provided Clamping sleeves can be easily introduced, provided this is necessary, and on the other hand hold the clamping sleeves reliably the brush strips or squeegee during a cleaning process for a tool.

In the container of the cleaning device according to the invention an inlet opening provided, into which a liquid feed body liquid-tight is used, the in the Deflects liquid entering the container. This has the advantage that even at a high fluid pressure no in the cleaning liquid flowing in the container over the open Container edge flows out. In addition, such Containers have the inlet opening at the bottom, and it is thus ensuring that container of the invention Cleaning device simplest in counters and other furniture can be installed because they have no side connections need.

It may also be advantageous if at least in the container a heating element is arranged. With a heating rod lets the cleaning liquid in the container heat up, and it An improved cleaning process always takes place if the tool surfaces to be cleaned with high-fat Polluted substances.

Is on the drain pipe with the liquid level up and descending float provided so is a fully automatic Operation of the cleaning device according to the invention possible. Must have a container quickly with cleaning fluid can be filled, this can with a temporally increased Inflow rate of cleaning fluid to be filled until the float has reached a certain level. At the Reaching a certain level gives the float a signal and slows the flow rate into the container, until the liquid level is reached, with which the Cleaning device according to the invention is operated. Of the Float is in this case a part of the cleaning unit. The cleaning liquid inflow rate or cleaning liquid outflow rate from the container is chosen so that the cleaning liquid is continuously cleaned by Pollutions are withdrawn from the container, the the cleaning of tools hinder or worsen. At the same time the liquid exchange rate is so large or chosen so small that an economic mode of operation of Cleaning device is possible.

The float has a switching contact, the contactless with one or more contacts outside the container cooperates, with the contacts control valves and / or regulate the liquid supply and / or drain into the container and / or fix. These measures ensure that that in a fully automatic operation of the Container of the cleaning device according to the invention not too strong and not too little with the intended cleaning fluid is filled. A stationary condition becomes always respected. If the liquid level for a steady state exceeded or exceeded, so opens either the liquid inlet valve, so in one given time unit more liquid in the container flows in or the drain valve is opened stronger so that a liquid accumulation in an inadmissible way and Way in the drain pipe is safely avoided.

The liquid feed body is preferably in cross section formed mushroom-shaped, and the liquid emerges from the Underside of the mushroom roof. Thus, a simple and reliable liquid feed body created, the one safe filling of the container allows and also a liquid distribution in the container then allows when the container Fully automatically cleaned when the drain pipe is removed shall be. The liquid inlet cross section is on the Liquid outlet cross-section adjusted so that the liquid drain more cleaning fluid per unit of time can dissipate as liquid flow into the container can.

In a further embodiment of the invention, the liquid feed body be designed as a tube that is extends over the entire height of the container and several Has liquid outlet openings for liquid supply opened at different heights of the pipe and can be closed. With such a Liquid feed body, the container for cleaning Tools are equipped, and the container over its height can be seen, so the pipe can over its entire axial extension cleaning fluid all sides so spray or spray that the container to the inner walls is completely cleaned and the soiled Cleaning fluid through the drain opening of the Can flow out of the container.

Thus, the inventive device for cleaning fully automatically operated by repeatedly used tools and be cleaned.

The drainpipe is pointed towards the liquid level at the end bevelled tapered so that the resistance in the transition of contaminated cleaning fluid into the drainpipe of floating on the surface of the liquid level in the container Particles or foams and / or bubbles minimized is and this without noticeable Aufstaueffekt trouble-free can flow through the drain pipe. The surface tension the cleaning fluid is broken so that no inadmissible impoundment of polluted with pollutions Cleaning fluid in front of the upper edge of the drainpipe can occur. In addition, there are notches or grooves the drain of the loaded cleaning fluid improve. The grooves or notches can be tapering also replace the edge on the drainpipe.

In the cleaning device according to the invention finds a defined liquid flow instead of from the liquid inlet for liquid leakage in stationary operation always is maintained. Through the continuous tracking of fresh, unused cleaning fluid and the continuous withdrawal of polluted, spent Cleaning fluid is the entire in the container Cleaning liquid continuously cleaned, and there can be no undue concentration of dirt particles occur in the cleaning fluid. Over a Heating or heating of the cleaning liquid is achieved that enriched in the cleaning fluid contaminants to the free surface of the cleaning fluid inflate and over the defined fluid flow be washed into the drainpipe. With the in the container maintained flow conditions are simultaneously all objects in the cleaning fluid constantly cleaned.

If necessary, additional means can be used in semi- or fully automatic Operation of the cleaning device of the floats against its buoyancy force present in the liquid be lowered with the impact that the inflow valve briefly opened for the cleaning fluid stronger is and an increased fluid exchange in the container takes place. This measure is always required if pollution in the cleaning fluid faster to be removed via the drain pipe.

In a fundamental embodiment of the invention, it is so possible that the knife in the cleaning unit forced using rails that contain no or brushes or rubber lips which represent the overall guidance curve as safe handling when inserting the knife into a Introductory track, which is above the water level and strip the coarse dirt in advance, and then afterwards under the water level is equipped with brushes, wherein the knife handle is not wetted with water, into the cleaning fluid dipped vertically and the tool, for example the knife blade between below the liquid level arranged in the longitudinal direction brush device is pulled and then by at least one located above the liquid level with fresh water purged injection unit flushed, and a further downstream above the liquid level, or above the injection unit arranged scraper for subsequent Dry by stripping the cleaning liquid after lateral displacement in the course of the execution movement in the area the stripping device pulled out of the container vertically becomes.

The entire cleaning unit in plug-in version can be used for overall cleaning or to replace the brushes and rubber lips be completely removed by the operator.

In a preferred embodiment, the container has a liquid inlet and a liquid drain, especially in such a way, that a pearly and / or continuous Removal or replacement of the cleaning fluid possible is. In a further preferred embodiment, the cleaning liquid heated, in particular, it comes from a Hot water source. In a further preferred embodiment takes place the discharge of the cleaning liquid at least in Continuous fluid exchange over the upper boundary of a liquid drain pipe within the Plaster unit that determines the fluid level.

In the operating state, for example, the fresh water supply of hot water as cleaning fluid up to the height the upper boundary preferably by means of the injection units, the above the water level and below the wiper lips lie, made. Also the standing arranged outside the container located fresh water inlet can fill, within the delimitation of the baffle plate to the tank bottom. The liquid level always is above the top row of the brush insert. Through the constant or temporary opening of the water inlet - as needed - can be forced by an arranged Baffle the liquid flow can be guided so that through an opening in the lower part of the baffle plate Only flow liquid upwards after the baffle plate passage can, whereby the ones located in the liquid area Dirt and grease and the like from the brushes Floating and not just for lighter specific Weight but also especially by the ascending Flow direction of the water in the overflow pipe of the upper Border washed away and thereby removed. By the stripping pre-cleaning of the guide rails outside of the water level and the subsequent complete covering the brushes with the cleaning liquid, namely the tool in the course of a single operation, through positioned Immersion guided outside of the liquid level Sideways passing below the water level and led Pulling out over the liquid level in subsequent Fresh water injection units followed by rubber lips to dry. This is a simple manual Handling without technical drive such as motor, etc. guaranteed. Cleaning and drying becomes a very simple, faster and 100% cleaning process in particular and also achieved for unskilled handlers, using the tool by the heated cleaning liquid, in particular hot Water is kept warm and cleaning after Slicing pies, soft cheese and the like fatty Goods were much easier. The knives are after cleaning - approx. 2 sec. Duration - appetizingly clean and dry without residues of previously cut goods, it is eliminated Change of water and the cleaning of usual knife quiver, what in High activity is often neglected. In contrast, the Cleaning process performed much faster.

After work, the cleaning unit including brushes with the in the container cleaning fluid by reinforced Water supply to be flushed. On the other hand can if necessary, the entire cleaning unit is pulled out after work and thus the cleaning liquid in the container dissipated by opening the water inlet becomes. A trouble-free replacement of the individual brushes and individual rubber lips, preferably held in strips and are therefore interchangeable at any time Cleaning unit outside the container now easily exchangeable as well as the entire maintenance especially related to Hygiene made easier. The cleaning unit can u.a. completely in a washing machine to be cleaned.

Instead of the cleaning unit can for additional cleaning of the Container a cleaning unit to the fresh water inlet be connected to the bottom of the container, such that by means of a perforated standpipe and sealed Cover against the container a liquid injection process clean the inside walls of the container. The drain of the polluted Water happens at the drainage pipe of the tank the place of the removed cleaning unit.

Further advantages will be apparent from the description and the attached drawing.

On the container 2 or on the cleaning unit 6 is a sharpening and / or Removal device for knives installed.

FIGS. 11 and 12 show a further embodiment of a cleaning device according to the invention with a container 32 into which a cleaning liquid 33 is filled. A cleaning unit is formed at least by a brush device 38, a stripping device 39 and a drain pipe 43, which is shown in FIG. 12. Brush and wiper lips of the brush device 38 and the wiper device 39 are held in retaining strips 45 , from which defective brush strips or squeegee strips can be pulled out and replaced by new ones.

Directly below the stripping device 39, still above the liquid level, an injection device 46 is arranged, which is concealed in FIG. 11 by the stripping device 39, but is shown in FIG. 12. With the spraying device 46, cleaned tool surfaces can be sprayed off or treated additionally above the liquid level of the cleaning liquid. For this purpose, a suitable liquid or steam can be used.

On a holding block 47 , the brush device 38, the stripping device 39 and the spray device 46 are attached. The holding block 47 has a passage opening to the open opening of the drain pipe 43 , which is also secured in the holding block 47. In the holding block 47 laterally acting clamping means 48 are provided, which are activated via a handle 48a in the arrow directions shown in Figure 11 so that they can be supported on the one hand so strong on the Behälterinnenwandungen that the holding block 47 is held immovably in the container 32, and on the other For example, the clamping means 48 can be released via a rotary movement of the handle 48a in such a way that the holder block 47 can be pulled out of the container 32 via the handle 48a with the drainage pipe 43 and the brush device 38, the stripping device 39 and the injection device 46.

The brush device 38 is largely different horizontally aligned levels below the liquid level the cleaning fluid of two pairs of brush strips formed, which are opposite, and the brush threads are so long that they touch each other or overlap as long as the brush strips are parallel next to each other run. A brush strip pair, the immediately below arranged the liquid level of the cleaning liquid 33 is, widens conically towards the free end, so that an object to be cleaned easily between the brush strips can be introduced at this point. Becomes the object to be cleaned moves in the direction of holding block 47, so the object to be cleaned is also in the section introduced, in which the opposite brush strips run parallel and has to be cleaned The object also has a length that takes him deep into the cleaning fluid 43 dive, then the corresponding Sections of the object to be cleaned also in introduced the underlying brush pair strips and there cleaned.

If the object to be cleaned up close to the holding block 47 introduced, it is also located between the squeegee the stripping device 39 and becomes the cleansing item pulled up in this area, so are the surfaces located between the brush strips of the object to be cleaned not only cleaned, but the cleaning liquid is to be cleaned from the Stripped off surfaces. The surfaces to be cleaned are After cleaning completely drip-free and dry.

The immediately below the liquid level arranged Brush pair is at least partially over its axial extent oriented obliquely towards the liquid level, thus also grip attachment surfaces at the transition, for example to be cleaned intensively to a knife blade can. For this it is advantageous if the retaining strips in This area are employed obliquely, so that in all retaining strips the same brush strips in different lengths can be used.

The drain pipe 43 is pointed at the upper edge in the holding block 47 Beveled so that floating on the liquid level Solid particles or foams and / or bubbles with the least Resistance to flow around the drain in the drain pipe 43 can. Surface tensions of the loaded cleaning fluid are degraded in the area of the liquid drainage. The reduction of surface tensions is supported at the liquid level, when in the edge of the drainpipe There are still grooves or notches in the circumference Edge of the drain pipe are attached.

The retaining strips 45 are preferably as clamping sleeves such designed that they brush strips or squeegee safe and able to keep them safe without them at one Cleaning process of a tool from its working position slip.

The container 32 has in its bottom a liquid inlet opening 50 , into which a liquid feed body 51 can be used liquid-tight, which deflects the inflowing liquid. In the bottom region, a heating rod 42 is also arranged, via which the cleaning liquid 33 located in the container 32 can be heated.

At the drain pipe 43, a float 53 is provided, which can move along the drain pipe 43 with a rising liquid level up and with a sinking liquid level down. If the container 32 filled so far that the cleaning device according to the invention can be put into operation, so the float 53 is located on the underside of the holding block 47. About a linkage, for example, attached to the handle 48a and passed through the holding block 47 up to the float 53, the float 53 is forcibly lowered during an up and down movement of the handle 48a and the float 53 is provided with contact means that can communicate without contact with circuit elements outside of the container 32, so can via the float position of the liquid inlet and outlet be controlled in the container 32. For example, in a filling stage, the liquid influx can be increased and in a final stage just before the operating state of the cleaning device is reached, due to the float height, the liquid supply amount per unit time is throttled so that no liquid can pass over the container edge. For example, the float 53 may communicate with contacts 54 (magnetic switches) which in turn emit signals for controlling and regulating valves that control and / or regulate fluid flow and outflow from the reservoir 32.

If the handle 48a is rotated in arrow directions 55 , the clamping means 48 can be retracted into the holding block 47 or extended out of the holding block 47. When the handle 48a is moved vertically up or down in arrow directions 56 , the float 53 can be positively lowered and a liquid level in the container 32 is simulated which is not adjusted. For example, over such a float displacement the liquid supply can be greatly increased over a short period of time, thus creating an additional purge in the container 32 in which a strong flow flow from liquid inlet to liquid outlet is created.

On the side wall of the container 32, a guide aid 57 for easy directional insertion of the drain pipe 43 is provided.

Guide rails 49 stiffen the container 32 and serve at the same time to guide when the holding block 47 in the Container 32 is introduced.

On the container, the drain opening 44 is tapered a plastic part designed so that one end of the drain pipe 43 guided introduced into the drain opening 44 can be. The inclined surfaces of the free end of the metallic Drain pipe 43 are so on the inclined surfaces of Plastic formed drain port 44 matched that of metallic edge of the drain pipe 43 liquid-tight the inclined surfaces of the drain opening 44 is seated. In addition, but not mandatory, the drain pipe 43 is still over one Seal sealed to the container 32.

A device for cleaning of reusable Tools has a container 32 into which a brush device 38 and one above the liquid level of the Cleaning liquid 33 lying scraper 39 is arranged is. The brush device 38 and stripping device 39 are indirectly or directly with a drain pipe 43 connected, the detachable and liquid-tight in a drain opening 44 of the container 32 is used. The brush device 38, the scraper 39 and the drainpipe 43 form with a holding block 47 a cleaning unit, the entirety is removable from the container 32, and for cleaning purposes can be cleaned in a dishwasher.
