Definitions
- the object of the invention relates to a device intended for the automatic and continuous production of ice cubes with a horizontal evaporator with vertical ducts.
- the apparatuses of machines with icicles in front of mar ⁇ expensive continuously, they must determine in an automatic way the size of the icicles to which the manufacture must be reversed, to pass, in demoulding and then the moment when all the icicles having fallen it is necessary to put back the apparatus in the refrigeration cycle and recirculate the water circuit to restart the production of the ice cubes.
- Known restart commands are determined by either pre-determined timers, which can restart the cold circuit before all the ice cubes fall, resulting in losses or even blockages or, in the opposite case, long ⁇ afterwards, which causes time and therefore production to be lost, that is to say temperature differences in the cooling circuit, identified by thermostats or pressure switches, panels, imprecise, difficult to troubleshoot and whose sometimes the settings have to be changed between summer and winter.
- the production requires good distribution of the liquid to be cooled on the exchange surface which use spraying by pumps and sprinklers, runoff by perforated booms or by immersion in water baths, systems which imply perfect horizontality, the absence of impurities totally disrupting the systems, or which consume a large amount of water which is thus wasted.
- the device according to the invention eliminates these drawbacks by avoiding the complicated devices controlling the setting in ice and the demolding because it is the ice cubes themselves which control the cycle of setting in ice and of demolding, the quantity of cooled water is limited and recovered and no part is in movement, only a floating element with foolproof movement ensures synchronization of the commands.
- the shapes of the ice cubes are classic and their volume corresponds to their use.
- the size of the reduced apparatus can be placed under a counter and the native alter operation is simplified because the regulation does not call upon mechanical elements, such as micro-motors, timer, pressos ⁇ tats, cams, thermostats.
- 11 is constituted by the combination first of a water intake in a channel in a peripheral gutter whose internal wall forming weir feeds a capacity provided with vertical tubular elements producing refrigerated cavities ensuring the formation of ice cubes, then a water supply to a collector regulated by a float.
- a pump sends the water into the channel in the gutter where the floating element ensures by its vertical translation the admission of the liquid, its stop, the control of the refrigeration and the heating of demolding as well as a demolding reinforcement by pushers, finally by an inclined ramp draining the ice formation water in a collector with recycling by ice pump.
- Figure 1 shows a longitudinal section view of the apparatus as a whole.
- Figure 2 shows on a different scale the positioning of the dimples in the capacity receiving the water for the formation of ice cubes and delimited by the channel or peripheral gutter.
- Figure 3 is a view showing the constructive detail of a tubular honeycomb.
- FIGS 4, 5, 6 show the phases of operation of the device.
- the device consists, fig 1, by a series of vertical cells 1 and others surrounded by coils 2 forming the evaporator of a refrigeration machine.
- the same serpentine can be used alternately for cooling and heating purposes by simply reversing the cycle of the refrigeration circuit.
- These cells are mounted on a surface 3 forming the capacity bottom and have their upper part 4 projecting.
- This ring 4 is pierced by triangular orifices 5 with a wide base in order to produce a water distributor arriving in large volume at the base with reduction as the filling takes place, in particular in the event of poor device horizontality.
- the base edge is formed by 5 'circular arcs or saw teeth in order to avoid ascending capillaries or heaps of ice during the flow fig 3.
- This surface 3 is clipped by a peripheral channel forming a gutter 6 connected by line 7 to a water intake 22 propelled by a pump 8 to an evacuation outlet 22 'and to channel 6.
- This water fills the peripheral channel or gutter 6 and pours after filling over the internal border 9 which forms the submersible capacity 3 ′ delimited by the gutter 6 which diverts it.
- a peripheral floating element is connected by a plate 14 carrying pushers 15 corresponding to each of the cells 1 located in their axis.
- the water is sent continuously into the capacity 3 ′ so as to discharge into the vertical cells 1.
- the water flows in a sheet along the vertical walls of the cells 1 and the ice forms by rapid stratification.
- the already cooled excess water flows on the ramp 16 and is taken up by the reservoir 17, the float 18 of which automatically regulates the flow rate of the water inlet 22.
- the water 19 is distributed, fig 4.
- the water is taken up by the pump 8 which fills the peripheral channel 6 through the conduit 7 and the inlet 13.
- the water level in the lateral channel is determined by the wall 9. because its flow rate is higher than that of the flow of overflows 10 and 11.
- the level of the floating element 12 is also adjusted by the level of the wall 9, and its stroke by the external wall 23 and of the guides.
- the water overflows the lateral channel and flows into the manufacturing tank 3 '.
- the flow regulators 5 distribute the water flow in the tubes 1, and the surplus flows through the ramp 16, the grid 20 ensures the filling of the collector 17.
- the floating assembly acts on an electric control which stops the water intake, the pump 8 stops working, the water flows through the orifices 10 and 11 along the ramp 16, then that the floating element while lowering causes the pushers 15, fig 6, which come to bear on the ice cubes.
- the floating element also controls the inversion of the refrigeration cycle which sends a hot fluid into the coils 2, which accelerates demolding.
- the ice cubes fall on the ramp 16 which brings them by passing over the grid 20 in a refrigerated container.
- the floating assembly is then in the low position, fig 6, and triggers the starting of the pump and the return to cold phases to start the cycle again, fig 4.
- the floating assembly is guided by the rods preventing any warping when lifting or lowering.
- the pusher 21 actuates the micro-contacts 24 ensuring the various commands.
- the floating element when it reaches the high position, the floating element does not stop the pump, but opens the water discharge solenoid valve 22, which cuts off the supply. 13 and ensures the renewal of the water in the collector 17.
Abstract
L'objet de l'invention concerne un dispositif destiné à la fabrication automatique et continue des glaçons avec évaporateur horizontal à conduits verticaux. Il est constitué par la combinaison d'abord d'une admission d'eau dans un canal en gouttière périphérique (6) dont la paroi interne (9) formant déversoir alimente une capacité pourvue d'éléments tubulaires verticaux (1) réalisant des alvéolages réfrigérés assurant la formation des glaçons, ensuite d'une alimentation en eau d'un collecteur régulée par un flotteur (12). Une pompe (8) envoie l'eau dans le canal en gouttière où l'élément flottant assure par sa translation verticale l'admission du liquide, son arrêt, la commande de la réfrigération et de l'échauffement de démoulage ainsi qu'un renfort de démoulage par poussoirs (15), enfin par une rampe inclinée (16) drainant les eaux de formation de glaçons dans un collecteur (17) avec recyclage par pompe du fluide à glace. Il est destiné à la fabrication de glaçons de petites dimensions pour rafraîchissement de boissons ou similaires, afin de mettre à la disposition des usagers un appareillage peu encombrant, à haut rendement et à faible consommation d'eau.The object of the invention relates to a device intended for the automatic and continuous production of ice cubes with a horizontal evaporator with vertical ducts.
