Definitions

  • the invention relates to a device, in particular arranged in refrigerated counters, for nebulizing continuously flowing liquids, in particular water, with an ultrasonic oscillator, the oscillating surface of which is covered by a liquid.
  • Appropriate devices are increasingly taking the place of classic humidification devices; in these, the mechanically circulating cold air flow sweeps over a water level, or coolant is sprayed through nozzles.
  • the particular advantage of ultrasonic vibrator nebulization is the surprisingly high degree of efficiency and extremely small droplet size, so that even the more distant counter areas are given a satisfactory level of moisture.
  • the disadvantage of corresponding devices is that mineral residues calcify or crust over the vibrating system. This varies depending on the so-called water hardness, but often leads to the need to replace the vibration system.
  • the object of the invention is to design a generic device in such a way that the ultrasonic vibrator is kept free from the aforementioned incrusting precipitation.
  • the service life of an ultrasonic vibrator is significantly increased. It also maintains its high efficiency.
  • the replacement part is no longer the vibrating system and the associated electronics, but a wall of the device that separates the liquid to be atomized from the other.
  • This can be a releasably attached separating film or simply an interchangeably assigned cup, in particular a plastic cup, which is of course matched to the vibration energy.
  • Its wall section facing the oscillating surface is in contact with the liquid which overlays the oscillating surface and serves exclusively as a sound transmission medium.
  • this liquid it can be purified, for example distilled water, possibly with antifreeze, which is in contact with the oscillator.
  • a structurally advantageous embodiment consists of a medium contact between the cup wall section and the liquid covering the oscillating surface with the interposition of a film on which the bottom is placed.
  • the liquid serving as the sound transmission medium is hermetically sealed.
  • a use-related assignment of a cup can advantageously be achieved in that a bracket spans the trough for the overlaying liquid while grasping the cup.
  • a measure which is favorable for the exchange consists in that the bracket is assigned to be folded away and carries the supply hose for the liquid to be atomized in the region of its folding axis. After the bracket is folded up, the cup can be easily inserted or replaced. The position of use is secured by the bracket advantageously having latching means at the free end, which with counter Interacting means interact below the edge of the tub. The rim of the cup can thereby be clamped in a favorable manner on the edge of the tub; the counter locking means are not in the way.
  • the measure still taken serves the same purpose of easy accessibility of the trough that the sensors of a level control device protruding into the cup sit on the bracket.
  • the trough bottom portion receiving the ultrasonic vibrator is raised to a chamber-forming pipe socket, the edge of which is covered by a membrane separating the overlying liquid from the liquid to be atomized as a wall section. Cups and tubs are integrated here. Instead of a whole cup, the membrane exchange is sufficient.
  • the refrigerated counter accommodating this device has a housing-like substructure 1.
  • a counter-shaped counter bed 2 rests on it, the latter forming the lower section of a goods room 3 which continues upwards into a counter top 4.
  • the customer closes this with a flip-up pane 5.
  • the counter top 4 merges into a worktop 6.
  • the upper end forms a so-called pay bar 7.
  • a cold source 9 rests on the bottom 8 of the base 1, preferably mounted on ribs.
  • a reservoir R of liquid F1, in particular water, extending parallel to the cold air flow path is switched on.
  • This continuously supplementing liquid F1, which is to be atomized for the purpose of moistening the goods, is located in a trough-shaped sagging recess of a wall or an exchangeable cup 12.
  • an ultrasonic oscillator 13 of the atomizing device extends at a distance.
  • This liquid F2 serves exclusively as a sound transmission medium.
  • This can be distilled water, in any case such a liquid in which no incrustations leading to the impairment of the oscillating surface 13 'are deposited.
  • Corresponding precipitation only forms in the cup 12 when using normal household water, mainly on the bottom of the cup or on the depression V (wall section 12 ').
  • the cup 12 is simply inserted into a trough 14 containing the liquid F2.
  • the trough bottom 14 ' is perforated centrally, so that the ultrasonic vibrator is introduced into direct contact with the liquid F2 surrounding it from below, with seals no longer shown.
  • the oscillator housing 15 containing the electronics etc. is located directly under the trough base 14 '.
  • an indirect contact between the cup 12 and the liquid F2 covering the oscillating surface 13 ' is selected with respect to the embodiment according to FIG.
  • This is done by interposing a film 16.
  • Its edge 16 ' is horizontally connected to the downwardly converging inner wall of the tub 14, for example by gluing or welding.
  • the film is so elastic that it sinks down a little when the cup 12 is placed on it.
  • the film hermetically seals the liquid F2.
  • the cup 12 is placed centrally. It is also conical to match the shape of the tub, but changes to a much flatter funnel shape in the upper quarter.
  • the cup rim also merges into a downward angled section 14 ′′. This creates an annular support channel 17 due to the symmetrical structure of the nested parts, which overlaps the front edge of the tub.
  • the inserted cup is secured by a bracket 18.
  • the latter extends over the tub 14. It extends in the diametral direction and is hinged in the area of its one end about a horizontal axis 19.
  • the free end of the bracket 18 is provided with a locking means 20 in the form of a groove. This interacts with a counter-locking means 21. This is a distance from the tub edge, i.e. H. below the same protrusion from the wall of the tub.
  • the portion of the free temple end which has detent means also serves as a handle 23.
  • the bracket has a roof shape.
  • the ridge line intersects the central longitudinal axis x-x of the connected cup / tub unit.
  • the bracket 18 Seen in cross section, the bracket 18 is U-profiled.
  • the U opening points downwards.
  • the ridge area is reinforced.
  • Two U parts 24 of the U web are also reinforced. The latter have holes.
  • a sensor 25 of a level locking device is embedded in each of these. The sensor ends protrude into the part of the cup 12 containing the liquid F1 to be atomized and can be pivoted out of the way about the axis 19 by folding the bracket 18 away.
  • the articulation-side end of the bracket 18 has an opening 26 in the area above the tub rim, specifically for receiving a supply hose 27 for the continuous supply of the liquid F1 to be atomized.
  • This hose which is made of rubber or plastic, tolerates the folding movement of the bracket without disadvantage and, due to its restoring force, even provides a certain amount of suspension in the sense of the overvoltage position of the bracket 18.
  • the hose 27 is laid in a bead 28 in a hood H which can be assigned to the counter bed.
  • a baffle wall 29 forms the upper end of the cup 12 containing the liquid F1.
  • the latter rests in a position-centered manner on the edge in a support shoulder 30 of the hood H.
  • the baffle wall covers the cup 12 only partially. The remaining cover is formed by, for example, the merchandise compartment floor 3 'consisting of several individual sheets.
  • the tub 14 is freely accessible.
  • the hood H has window-shaped openings 32 above the cup, specifically in a zone above the trough, for the passage of the cold air stream crossing the rising damp mist.
  • the wall section 12 '(depression V) forming the cup base is reduced in its wall thickness.
  • the tub 14 is deep drawn into a stand St. This stand can either be placed on the floor of the hood H and fixed in position, or it can be supported on the counter bed 2.
  • the tub is simply suspended in a central opening 31 corresponding to the funnel shape of the tub.
  • the trough bottom section 14 'receiving the ultrasonic vibrator 13 is pulled up to form a chamber-forming pipe socket 35. Its upward-facing end edge is covered by a membrane 36 as wall section 12 '. The membrane is held with the help of a clamping ring 37.
  • This membrane made of rubber, plastic, metal or the like can be replaced. It forms a partition between the liquid F2, which overlays the oscillating surface 13 'and serves as a sound transmission medium, and the liquid F1 intended for atomization.
  • the trough 14 in principle also forms the cup, which does not need to be replaced, however, but only the membrane 36.
