Description

MACHINE FOR MAKING ICE CUBES
DESCRIPTION The present invention refers to a machine for making ice cubes, of the type comprising a device for spraying water into a plurality of ice formation cells externally associated with the evaporator of a refrigerator group, a recirculation pump which through a connection pipe feeds the spraying device with water to be transformed into ice taken from a storage tank, and an access hatch to a storage tank for the formed ice cubes .
It is known that such machines often have the drawback of substantially complicating the access to the inner parts for inspection, maintenance and cleaning, foreseeing an assembly of the machine which hinders or even prevents the subsequent disassembly of one or more of its parts.
Indeed, many of the internal components of the machine must frequently be checked to ensure the correct operation of the machine, for example the recirculation pump must be easily accessible for the cleaning of the relative filter, just as it is necessary to access the inside of the storage tank for the water to be transformed into ice for the removal of limescale which has progressively been able to form. As is known, machines for producing ice cubes exploit the force of gravity to expel the left-over water at the end of every ice production cycle as well as the water resulting from the melting of the ice cubes present in the storage tank. For the correct operation of the leftover water drainage system, therefore, the drain for water from the machine must be placed at a certain height above the connection point to the water drainage network, a thing which often means having to keep the machine in a raised position which is particularly bulky and inconvenient.
The technical task proposed of the present invention is, therefore that of realising a machine for making ice cubes which allows the aforementioned technical drawbacks of the prior art to be eliminated.
In this technical task a purpose of the invention is that of realising a machine for realising ice cubes which is easy to disassemble into its constituent parts to ease the maintenance, inspection and cleaning operations. Another purpose of the invention is that of realising a machine for making ice cubes which allows the complete drainage of the left-over water even in conditions of negative height difference between the drain for the leftover water from the machine and the connection point to the external water drainage network, in other words even if such a connection point to the external water drainage network is higher with respect to the drain for the left-over water from the machine .
The last but not least purpose of the invention is that of realising a machine for making ice cubes which is structurally simple and cost-effective. The technical task, as well as these and other purposes, according to the present invention are accomplished by realising a machine for making ice cubes comprising a device for spraying water into a plurality of ice formation cells, at least one recirculation pump which through at least one connection pipe feeds the spraying device with water to be transformed into ice taken from at least one storage tank, and an access hatch to a storage compartment for the formed ice cubes, characterised in that at least first connection means are foreseen for connecting at least one of said hatch, said spraying device and at least one portion of said tank for storing the water to be transformed into ice in such a way that it can be removed from the machine.
The removable connection between the parts of the machine not only eases assembly, some connections being able to be realised with automatic snap mechanisms, but also offers the undeniable advantage of allowing easy access to the inside of the machine for inspection, maintenance and cleaning operations .
The present invention also discloses a machine for making ice cubes comprising a device for spraying water into a plurality of ice formation cells, at least one recirculation pump which through at least one connection pipe feeds the spraying device with water to be transformed into ice taken from at least one storage tank, and an access hatch to a storage compartment for the formed ice cubes, characterised in that it has at least one drainage tank for the water that melts from the ice cubes present in the storage tank and from the cells during the production of the ice cubes, and at least one drainage pump suitable for conveying the water collected in said drainage tank towards the water mains .
The drainage system allows complete drainage of the leftover water without needing to foresee building work for adaptation of the height of the connection point of the external water drainage network or devices outside of the machine, for example a drainage pump outside of the machine.
Other characteristics of the present invention are defined, moreover, in the subsequent claims.
Further characteristics and advantages of the invention shall become clearer from the description of a preferred but not exclusive embodiment of the machine for making ice cubes according to the finding, illustrated for indicating and not limiting purposes in the attached drawings, in which: figure 1 shows a front view of the ice cube maker; figure 2 shows a top side section view of the ice maker taken out from the support frame; and figure 3 shows in detail the attachment system between the spraying device and the connection pipe of the recirculation pump; figure 4 shows in detail another embodiment of the attachment system between the spraying device and the connection pipe of the recirculation pump.
With reference to the quoted figures, a machine for making ice cubes is shown, wholly indicated with reference numeral 1. The machine 1 comprises an ice cube production unit wholly indicated with 3 supported by a framework of the machine 1 wholly indicated with 5.
The ice cube production unit 3 has a casing 18 and comprises a spraying device 7 formed from a plurality of nozzles for spraying water into a plurality of ice formation cells 9 externally associated, that is on the opposite side to that where ice is formed, with the evaporator 10 of a refrigerator group (not shown) in which the refrigerating fluid circulates.
The cells 9 are externally heat insulated to keep the temperature as low as possible thus limiting the melting of the ice as it progressively forms .
The refrigerating group comprises a compressor suitable for feeding the condenser equipped with a fan, and the compressor is also connected to an accumulator in turn connected with the evaporator and then once more with the compressor. The unit 3 comprises at least one, in particular just one recirculation pump 11 which through at least one pipe, in particular just one connection pipe 13, feeds the spraying device with water to be transformed into ice taken from at least one tank, in particular just one storage tank 15 in turn comprising a portion, in particular its base portion 27 engaged with the rest of the body 29 of the storage tank 15. The unit 3 also has a zone 17 for conveying the ice cubes towards an ice cube storage compartment 19 from which it is separated through a front hatch 21. The hatch 21 comprises a first fixed and removable element 22 and a second rotatable and also removable element 24.
The fixed element 22 supports the front part of the evaporator 10 and protects the storage compartment 19 from splashes coming from the sprayer 7.
The rear part of the evaporator 10 is, on the other hand, supported by an inner shoulder 12 of the casing 18 of the evaporator 10.
Preferably, the rotatable element 24 is formed from a panelled flap supported canti-levered about a substantially horizontal rotation pin 23.
The panels of the flap 24 are kept slotted on the rotation pin 23 by a pair of stops mounted at the opposite ends of the rotation pin 23.
The rotation pin 23 of the flap 24 can be supported directly by the fixed element 22, by the casing 18 of the evaporator
10 or by a part 16 integral with it.
The spraying device 7, present in the conveying zone 17, comprises an inclined plate 25 for sliding the ice cubes towards the build-up compartment 19.
The machine 1 foresees at least one first removable connection means for connecting at least one from the hatch
21, the spraying device 7 and the base 27 of the water storage tank 15 in such a way that it can be removed from the machine 1.
More specifically, the machine 1 comprises first connection means for connecting the elements 22 and 24 of the hatch 21 in such a way that they can be removed from the machine 1.
Such first removable connection means are in the form of attachment screws of the first element 22 of the hatch 21 to an insert 16 fixed to the casing 18 of the evaporator 10 and snap means comprising snap housing seats suitable for housing the stops on the ends of the rotation pin 23 of the second element 24 of the hatch 21.
As an example, such snap seats can be open bushes 33 having a throttle for opening to slightly less than the diameter of the stops at the ends of the rotation pin 23 so that such stops can be snap inserted there exploiting elastic deformation.
Such snap seats, as stated, can be formed from the insert 16 of the casing 18 of the evaporator 10, as illustrated, or alternatively even directly from the casing 18 or from the element 22 of the hatch 21, just as such a fixed element 22 can be fixed directly to the casing 18.
The machine 1 also has second removable connection means for connecting the spraying device 7 in such a way that it can be removed from the machine 1.
Such' second removable connection means comprise at least one shoulder 37, in particular a single support shoulder, and at least one locking seat 39, in particular a single locking seat, for the sliding plate 25 of the spraying device 7.
The support shoulder 37 is formed from an inclined inner surface of the rear wall 39 of the casing 18 on which the rear edge of the plate 25 abuts, whereas the locking seat 39 comprises a substantially vertical front wall of the casing
18, arranged substantially below the hatch 21, in which an upturned U-shape of the front edge of the plate 25 can be locked.
For the complete removal of the spraying device 7 from the machine 1 it is necessary to remove the coupling between the spraying device 7 and the connection pipe 13 to the recirculation pump 11.
Such second removable connection means thus also comprise removable coupling means between the connection pipe 13 and the recirculation pump 11.
In figure 3 such coupling means are of the snap type and comprise a discharge joining element 41 of the connection pipe 13 and a return joining element 43 to a collection chamber 45 of the spraying device 7.
Still in figure 3, the joining element 41 has a substantially square plate 47 capable of sliding in a guide 49 of the joining element 43 up to an end stop in which an elastically yielding tab 51 of the joining element 41 is snap locked in a relative snap seat (not illustrated) of the joining element
43.
Alternatively, in figure 4 such coupling means are of the pressure locking type and comprise, for example, a tubular T- shaped joining element 42, which is connected at a first end to the discharge of the connection pipe 13, at a second end to an axially open locking element 44 which extends from a collection chamber 45 of the spraying device 7, and which is fixed, for example glued, at the third end of the tank 29.
Still in figure 4, the locking element 44 carried sealing means, in particular an O-ring which creates a seal inside the tubular joining element 42.
The machine 1 also has third removable connection means for connecting the base 27 of the water storage tank 15 to the rest 29 of the body of the storage tank 25.
Such connection means can be in the form of screw, bayonet or mechanical locking coupling means between the base 27 and the remaining body 29 of the water accumulation tank 15.
The machine 1 also foresees indication means for periodically indicating the need for maintenance, inspection or cleaning.
Such indication means (not shown) can be in the form of warning lights, in particular LEDs, which light up after a certain number of hours of operation and/or of lifetime of the machine 1 or after a number of hours that takes into account these and other operating parameters taken individually or in combination..
An extremely advantageous characteristic of the machine is that of foreseeing at least one drainage tank (not shown) for the water which melts from the ice cubes present in the ice storage tank and from the cells during the production of ice cubes, and at least one drainage pump (not shown) suitable for conveying the left-over water co ing from the drainage tank towards the mains water drainage network.
