Definitions

  • the invention relates to a cutlery cleaning device of the type specified in the preamble of claim 1.
  • the cutlery is usually only placed in one copy at a time, ie a knife and possibly a fork and spoon. This applies to the private sector as well as to most restaurants, hotels and guest houses. However, it has been shown that this does not meet the needs of many people, particularly at breakfast, when honey, sausage, jam and the like are consecutively consumed, the order of course being arbitrary. So you are forced to spread sausage or cheese on the bread or rolls with the same knife on which the food residues of the previous spread, for example a nut-nougat cream, are still attached. It is not always possible to provide two or more knives for each person, because this often fails due to the number of cutlery available.
  • a cutlery cleaning device is known from FR-A-883 044, which consists of a liquid-receiving container with a lid.
  • the lid has two openings for inserting a knife and between the two openings there is a device for wiping off food particles.
  • This cutlery cleaning device is simple in construction, but cold water is used because no measures have been taken to keep the water at a certain temperature or even to heat it.
  • US-A-3,725,641 describes a liquid-filled container which is made of metal and is provided with an electrical heating device. The container is located in a pot-shaped plastic housing that is only accessible from the opening at the top, which makes assembly and repair work difficult. It is therefore the object of the invention to provide a cutlery cleaning device of the type mentioned, with which the cleaning effect is improved and which is designed to be more service-friendly.
  • the invention is particularly characterized in that the cavity formed between the pot and the jacket has a heat-insulating effect. This annulus between The jacket and pot can also be filled with a heat-insulating material.
  • the cutlery cleaning device according to the invention makes it possible for everyone at the table to easily free their cutlery, in particular knives, from food residues, in order to subsequently use the cutlery with another dish, preferably spread, without affecting the taste of the subsequently selected dish is influenced by remnants of the previous one.
  • the appropriately designed opening in the lid makes it easy to insert a knife and immerse it in the liquid in the container. Without lingering in the liquid, the knife can be pulled out along the device for wiping off food particles and is thus already cleaned.
  • the lid which contains the stripping device
  • the type of attachment can be carried out, for example, by a frictional connection, by a thread, by a bayonet lock or in some other suitable way. It is important, however, that the lid not only lies loosely on the container, so that the lid is not lifted when the knife is stripped along the stripping device.
  • the casing can have a radially inwardly directed collar with an annular groove arranged coaxially to the casing, into which the upper end of the pot is pressed.
  • the pot can also be held in such a way that its upper edge lies on a radially inward projection of the jacket and rests with its base on supporting elements of the footplate.
  • a rubber seal is used near the upper end of the pot or jacket to prevent water from the pot from getting into the annular space between the jacket and the pot.
  • a preferred embodiment of the heating device is that it comprises at least one PTC resistor and the PTC resistor rests on the one hand on the bottom of the pot and on the other hand on a connecting plate and the latter is supported on the footplate by means of a spring element.
  • This measure has several advantages, which can be seen in particular in the fact that PTC resistors act as self-regulating heating elements and the metallic pot and the connection plate simultaneously serve as electrical contacts for the PTC resistors. In this way, there is minimal construction effort and good functionality.
  • the spring element ensures that a good contact of the contact surfaces is always guaranteed.
  • a heating device in the form of an electrical heating spiral can also be provided, which surrounds part of the outer surface of the pot.
  • Such heating coils have a large heating capacity, so that a rapid heating of the water in the pot is made possible. Since such heating coils generally have no self-regulating properties, it is advisable to provide a temperature controller.
  • a switch is present, which is connected between the heating device and a connecting cable.
  • the device for stripping food waste consists of wiper lips, which are arranged on both sides of slots.
  • the wiper lips extend over the entire length of the slots and the width of the slot remaining between the wiper lips is less in the unactuated starting position than the thickness of the cutlery to be cleaned.
  • An extremely low manufacturing effort for the wiper lips is achieved if the wiper lips are designed as thin-walled lips molded onto the cover and from its plastic material.
  • the arrangement of the opening for inserting the cutlery and the slots with the wiping lips differs as required, it being possible to take into account how many people who are eating the same cutlery at one table are provided with such a cutlery cleaning device.
  • a useful embodiment is that the opening for inserting the cutlery in the middle of the lid and the slots are arranged in a star shape starting from the opening.
  • each slot is provided with a conical extension towards the opening and that the opening between two adjacent extensions is designed to be arcuate, the apex of the arc is directed into the opening.
  • An alternative embodiment of the lid is that two openings are provided for introducing the cutlery and at least one slot is assigned to each opening. Such an arrangement is both in a round cutlery cleaning device or lid and in an elongated Shape possible. For space-saving division, the openings are diametrically opposite one another and the slots are arranged parallel to one another and in the opposite direction.
  • a device for sharpening knife blades can be provided, by means of which the knife blade is sharpened simultaneously and without additional effort for the user each time the knife is cleaned.
  • a device can expediently be designed such that a device for sharpening knife blades is arranged at the end of the slot remote from the opening, said device comprising at least one sharpening steel fastened in or on the material of the cover.
  • the jacket 14 is releasably attached to the base plate 15 by pressing, screws, clips or in any other suitable way.
  • An electric heating device is provided on the underside of a bottom 19 of the pot 13, which comprises several PTC resistors 20 connected in parallel.
  • the PTC resistors lie on a connection plate 21 which is supported on the base plate 15 by means of a spring element 22.
  • An electrical connection cable 23 is guided through the base plate 15 and each wire of the connection cable 23 is electrically conductively connected to the connection plate 21 and the pot 13. Since the PTC resistors 20 regulate the heating power themselves as a function of the temperature, additional regulators and switches as well as connecting lines are not required. Vent openings 24 are provided in the base plate 15.
  • the upper end 13 * of the pot 13 is sealed by being pressed into the groove 16 in the bead 17, so that even when the pot 13 is overfilled or by inclining, no water enters the space between the pot 13 and the jacket 14 or foot part that accommodates the electric heating device 15 can reach.
  • Other measures can also be provided for suitable sealing.
  • a cover 10 is arranged, in which an opening 11 is provided, the shape of which will be discussed in more detail later.
  • the lid 10 can be removed from the jacket 14, but it must sit on the jacket 14 in a friction or form-fitting manner, so that the lid 10 is not lifted off when the cutlery is cleaned.
  • the pot 13 is filled with hot or heated water up to a certain height not far from the lid 10.
  • the knife is inserted with its blade through an enlarged part of the opening 11 into the pot 13, then moved laterally between two scraper lips and then pulled upwards between the scraper lips 12, thereby removing food residues adhering to the blade.
  • FIG. 3a and 3b show an enlarged view of the detail X in Fig. 1. From this view it can be seen that the lid 10 has an opening 11 which is formed at certain points to a narrow slot 25 which is parallel to itself this extending scraper lips 12 is limited.
  • the scraper lips can be attached to the cover 10 as separately manufactured parts made of a rubber-elastic material, but the configuration as a thin-walled scraper lips formed on the cover material 10 from its plastic material is particularly advantageous, which thus arise during the production of the cover without an additional operation.
  • FIG. 3a shows the wiper lips in their normal position
  • FIG. 3b shows the wiper function of the wiper lips 12. Since the width of the slot 25 is less than the thickness of a knife blade 26, the wiper lips 12 bend upward in the drawing) in the direction in which the knife blade 26 is moved and, due to their good contact, graze on both sides of the knife blade 26 the adhering food residues. The direction of movement of the knife blade 26 is indicated by the arrow 27.
  • FIG. 4 shows a top view of the cover 10, which has the opening 11 in its center, from which six slots 25 extend in a star shape.
  • the slots 25 are provided on both sides with wiping lips 12.
  • Each slot 25 is provided with a conical extension 28 towards the opening 11, the opening 11 being designed in an arc shape between two adjacent extensions 28. This arcuate design and the conical extensions 28 serve to facilitate the insertion of the knife blades into the slots 25.
  • the line II-II shows the section in which the cover 10 is shown in FIG. 1.
  • FIG. 5 shows the top view of another embodiment of the cover 10, which is particularly suitable for. Cutlery cleaning devices with a smaller diameter are suitable. There are two openings 29 in the cover 10, each of which is assigned a slot 25, the slots 25 - as already described for FIG. 1 - being equipped with wiper lips 12. The knife is cleaned in the manner described for FIG. 4.
  • a cutlery cleaning device 1 which essentially consists of a metallic pot 30 and a base plate 31, a stepped housing shell 32 and a cover 33.
  • Base plate 31, housing jacket 32 and cover 33 are made of plastic.
  • the bottom of the pot 30 rests on support elements 34 of the base plate 31.
  • the upper edge of the pot 30 lies on a radially inward projection 35 of the housing shell 32 and a rubber seal 36 is provided on the outer surface.
  • the rubber seal 36 prevents water from entering a cavity 37 which is formed between the pot 30 and the housing shell 32.
  • the housing jacket 32 has a step 32 in its lower area, so that the housing jacket 32 has a larger diameter and thus also a greater distance from the pot 30 in this area.
  • a heating device 38 in the form of an electrical heating spiral, the ends of which are connected on the one hand to a connecting cable 39 and on the other hand to a switch 40.
  • the lid 33 - like the lid 10 already described - has an opening for inserting the blade of a knife 42 and wiping lips 43 for removing the food residues from the blade 41.
  • the handling for cleaning the knife 42 is the same as that already shown in FIG 1 has been described.
  • Fig. 2 shows an enlarged view of a section of the cover 33 with a device for sharpening a knife blade.
  • This device comprises a sharpening steel 44 embedded in the plastic material of the cover 33 and projecting into the slot 25.
  • the knife 42 is pulled out, it is pulled along the sharpening steel 44 with the cutting edge and thus sharpened at the same time during each cleaning process.
