Description
MAKER OF ICE IN PARTICLES WITH ELECTRIC PUMP
DESCRIPTION
The present invention relates to a maker of ice in particles with an electric pump.
It is known that the makers of ice in particles comprise - among other things - a supply circuit of liquid-phase water to a sprayer which suitably sprays the water in the alternately cooled and heated cells in which the ice in particles is formed,
As is known, the supply of the water to the circuit occurs by means of a pump, generally electric, the impeller of which is positioned in a suitably shaped collection tank inside a technical ice making compartment, positioned in the machine body of the ice maker.
It is also known that maintenance and/or cleaning interventions are often necessary on the pump and in particular on the impeller, substantially the only moving member in the ice maker, but of fundamental importance for the productivity and production quality of the ice particles.
Part of the known art is the configuration of the collection tank provided with an openable lower access door, which allows the operator to access the impeller and the pump body, and to remove it for maintenance work.
However, such access is particularly complex for the operator and penalises the production of the ice maker, especially for rapid interventions which do not affect the activity of the machine.
There is therefore a need to improve the structure of a maker of ice in particles of known type, and in particular of the structure of the electric pump for supplying the liquid-phase water circuit. The technical task of the present invention is therefore to make a maker of ice in particles which allows to eliminate the decried technical drawbacks of the prior art.
As part of this technical task, an object of the invention is to make a maker of ice in particles which comprises an electric pump which is easy to assemble and disassemble in the machine body.
Another object of the invention is to make a maker of ice in particles comprising an electric pump and an impeller of easy mutual assembly and disassembly.
A last but not least object of the invention is to make a maker of ice in particles comprising an impeller which is easy to assemble and disassemble with respect to the drive shaft of the electric pump.
The technical task, as well as this and other objects, according to the present invention are reached by making a maker of ice in particles, comprising a compartment provided with an access door, a collection tank for collecting ice in particles positioned in said compartment, at least one evaporator having forming cells for forming the ice in particles, at least one sprayer of water in the cells, a supply circuit for supplying liquid water to said sprayer including a liquid water collection tank positioned in said compartment, at least one pump for circulating said liquid water positioned in said liquid water collection tank, a support structure for supporting said pump, an electric motor for driving the pump, and a support frame for supporting said electric motor, wherein said circulation pump includes a pump body supported by said support structure, an impeller positioned in the pump body and a pipe by means of which the pressurised liquid-phase water is sent to the sprayer, and wherein said electric motor has a drive shaft for driving the impeller, characterised in that quick assembly and disassembly means of said pump body, and quick coupling and release means between said impeller and said shaft are included.
In an embodiment, quick coupling and release means is provided between said support structure and said frame.
In a preferred embodiment, quick coupling and release means is provided between said pump body and said support structure.
Other features of the present invention are defined, moreover, in the subsequent claims.
Further features and advantages of the invention will become more apparent from the description
of a preferred, but not exclusive, embodiment of a maker of ice in particles according to the invention, illustrated by way of indicative and non-limiting example in the appended drawings, in which: figure 1 shows a section of overall assembly of an ice maker of known type; figure 2 shows a perspective view of the electric pump and support unit; figure 3 shows an exploded view of the electric pump unit; figure 4 shows a detail view of the mutual attachment elements of the pump shaft to the impeller; figure 5 shows a vertical section of the electric pump.
The following detailed description makes reference to the appended drawings, which form a part thereof.
In the drawings, similar reference numbers typically identify similar components, unless the context indicates otherwise.
The illustrative embodiments described in the detailed description and in the drawings are not to be understood as limiting.
Other embodiments may be used, and other modifications may be introduced without deviating from the spirit or scope of the subject matter represented here.
The aspects of the present description, as generally described in the present context and illustrated in the figures, may be arranged, replaced, combined, and designed in a wide variety of configurations, which are all explicitly envisaged and part of this description.
With reference to the figures mentioned, a maker of ice in particles is shown indicated overall with the reference number 1.
The maker 1 of ice in particles comprises at least one compartment 2 provided with an access door 3, and at least one collection tank 4 for collecting ice in particles positioned inside the compartment 2.
The maker 1 of ice in particles then comprises at least one evaporator 5 having a plurality of forming cells 6 for forming the ice in particles, onto which a water sprayer 7 sprays liquid-phase water supplied by a supply circuit.
The supply circuit in turn comprises a liquid-phase water collection tank 8 positioned inside the compartment 2, at least one electric pump 9 for circulating liquid-phase water positioned in the collection tank 8, a support structure 10 for supporting the pump 9, an electric motor 11 for driving the pump 9 and a support frame 12 for supporting the electric motor 11.
In turn, the circulation pump 9 includes a pump body 13 and an impeller 14 positioned inside the pump body 13 driven by means of a drive shaft 15 by the electric motor 11.
The circulation pump 9 is connected to a pipe 9 A by means of which the pressurised liquidphase water is sent to the sprayer 7.
Innovatively and advantageously, according to the present invention, quick assembly and disassembly means of the pump body 13 is provided: such quick assembly and disassembly means includes snap coupling and release teeth 21 between a first piece 22 and a second piece 23 of the pump body 13 integral with the support structure 10.
The first piece 22 includes a filtering wall 24 for the entry of liquid water into the pump body 13, and the second piece 23 shaped for the introduction and extraction of a terminal 18 rigidly but removably connected to the shaft 15 in/from the pump body 13.
Suitably, between the first piece 22 and the impeller 14, a radial diffuser 14 A is inserted which concentrates the liquid-phase water being sucked towards the axis X of the pump body 13.
Advantageously, quick coupling and release means is provided inside the pump body 13 between the impeller 14 and the drive shaft 15.
In a first embodiment, the quick coupling and release means between the impeller 14 and the drive shaft 15 is interacting magnetic elements, including a magnetic element 16 fully
incorporated in the impeller 14 and a magnetic element 17 fully incorporated in the terminal 18 of the shaft 15.
Both magnetic elements 16, 17 are permanent magnets.
In a second embodiment, the quick coupling and release means between the impeller 14 and the drive shaft 15 is snap or bayonet mechanical means.
Operatively, the impeller 14 and the terminal 18 of the shaft 15 rotate solidly by engaging projections 19 on the impeller 14 in recesses 20 of matching shape on the terminal 18.
Innovatively and advantageously, the pump body 13 is made in a single piece with the support structure 10.
Innovatively and advantageously, mechanical quick coupling and release, typically snap, means is also provided between the support structure 10 of the pump 9 and the support frame 12 of the electric motor 11.
Advantageously, moreover, according to the present invention, the liquid-phase water collection tank 8 is fixed inside the compartment 2 in an integrally removable manner, typically by means of a rotational-translational movement thereof.
The operation of a maker of ice in particles with electric pump according to the invention appears clear from the description and illustration and, in particular, is substantially as follows. For cleaning and maintenance operations, the operator accesses inside the compartment 2 of the (deactivated) machine through the door 3, and removes the collection tray 8 with a rotational- translational movement, thus being able to access the electric pump 9.
He releases the pipe 9 A from the engagement with the electric pump 9.
By activating a first quick release, he releases the support structure 10 of the pump 9 from the support frame 12 of the electric motor 11.
With a subsequent quick release, he disengages the attachment between the impeller 14 and the
drive shaft 15, typically in a first embodiment between the magnetic element 16 incorporated in the impeller 14 and the magnetic element 17 incorporated in the terminal 18 of the shaft 15.
The support structure 10 integral with the pump 9 is thus released and disengaged.
By activating the quick release of the snap coupling and release teeth 21 between the first piece 22 and the second piece 23 of the pump body 13 integral with the support structure 10, the operator can directly access the impeller 14 and the filter 24, removing them for the planned cleaning and/or maintenance operations.
In practice, it has been found that a maker of ice in particles with an electric pump according to the invention is particularly advantageous because it comprises an electric pump which is easy to assemble and disassemble in the machine body.
Another advantage of the invention is that of making a maker of ice in particles comprising an electric pump and an impeller of easy mutual assembly and disassembly.
A further advantage of the invention is to make a maker of ice in particles comprising an impeller which is easy to assemble and disassemble with respect to the drive shaft of the electric pump.
A maker of ice in particles as conceived herein is susceptible to many modifications and variants, all falling within the scope of the inventive concept as defined by the claims; furthermore, all the details are replaceable by technically equivalent elements.
The materials used, as well as the dimensions, may in practice be any whatsoever according to needs and the state of the art.
