Definitions

  • the present invention relates to an apparatus for automatically and continuously making ice cubes.
  • the presently available apparatus for automatically and continuously making ice cubes are generally operatively provided with an evaporating assembly,which is immersed in a water holding small tank,in order to freeze water to form the ice cube about the bottom lugs or the evaporator.
  • Yet another problem affecting prior art apparatus is that of detecting the ice amount which is present in the reserve tank,in order to provide the apparatus with the stop command,as said ice amount has reach­ed the preset level.
  • thermostatic assemblies wich are rather complex,or comparatively high cost and poor reliabi­lity.
  • the task of the present invention is to overcome the above mentioned drawbacks,by providing an apparatus for automatically and conti­nuously making ice cubes which affords the possibili­ty of carrying out the automatic ice making operative cycles without the need of using complex driving systems,while reducing to a minimum the level control means.
  • Yet another object of the present invention is to provide such an ice making machine or apparatus including a single driving or operating variably counterweighted member which,in addition to precise strictlyly operating,has a greatly simple structure,thereby remarkably reducing its making cost.
  • Yet another object of the present invention is to provide such an apparatus,for automatically and continuously making ice cubes,which is very safe and reliable in operation.
  • an apparatus for automatically and continuously making ice cubes characterized in that it comprises a thermally insulated supporting frame defining in its inside an ice collecting vessel, accessible from the outside and overlying a water collecting tank,a pump for supplying water to an ice making assembly communicating with said water collect­ing tank.
  • the above mentioned ice making assembly comprises an evaporator,which may be immersed in an ice making small tank supported at one end of a lever mechanism which is counter­weighted,at the other end,by a variable weight small tank provided with a water discharging siphon member which may be actuated by said pump for driving,with preset cycles,said lever mechanism.
  • Figs.1,2 and 3 schematically illustrate cross-sectional views of the ice making apparatus according to the present invention,respectively in its operative steps of supplying water to the water holding small tank,siphon member actuating and simultaneous lowering and raising of the tank 23;
  • Figs.4 and 5 illustrate,on an enlarged scale, the ice making assembly,with the counterweighted lever mechanism represented in its two end of stroke positions.
  • the ice making apparatus comprises an auoter supporting frame, indicated generally at the reference number 1,which is thermally insulated and defines,in its inside, an ice collecting vessel 2 which is closed at the top by an upper wall 3 for supporting the ice making assembly,indicated at the reference number 4 and which will be illustrated thereinafter.
  • the ice collecting vessel 2 overlies a water collecting or holding tank 5,consisting of a tank body provided with a safety discharging siphon member 6 and a key locking system indicated at 7 and illustrativelyed in its mounting position.
  • the water collecting tank 5 may be manually filled or it may be coupled to the water supply system,which is controlled by an electric valve 8.
  • a cover member 10 which may be located at two different positions.
  • a sensing member 13 for detecting the presence of water in the water collecting tank 5 is arranged inside said water tank.
  • the ice making assembly comprises a refrigerating system 15,operating either with air or water condens­ing,which is coupled to lug evaporator 16,which are preferably made of nickel clad copper.
  • the lugs 16 of the evaporator are supported by a supporting frame 17,preferably made of an optically transparent material,thereto there is coupled a known stirring member 18,operating a stirring blade 19 which sense and adjust the cube thickness.
  • Registering abutment members 20 are furthermore provided,which,as it will appear more clearly therein­after,adjust the height of said ice cubes.
  • the lugs 16 may be introduced into an ice making small tank 21 which is mounted at one end of a swinging lever 22,said lever being counterweighted, at the other end thereof,by a variable weight small tank 23.
  • the tanks 21 and 23 are swingably mounted with respect to the counterweighted lever mechanism 22 and the pivot pins thereof are arranged above the centers of gravity of the small tanks,thereby said tanks are always held,by gravity,in a vertical po­sition.
  • the small tank 23 is provided with a siphon member 24 which discharges water downward to convey the water to the water collecting vessel 5,through the provision of covering water discharging cup members 26 which are arranged horizontally and vertically,to recover the water level in the water tank 21.
  • the vertically extending cup member 27 may be raised in order to facilitate the introduction of water into the tank 5.
  • the water outlet 12 of the pump discharges into the upper portion of the counterweighted tank 23 and operates,as it will become more apparent thereinafter,to actuate the siphon member with preset operating cycles,to discharge water.
  • the ice making vessel 21 is provided at the bottom thereof with a projecting portion 30 which will abut,during its swinging movement by the counterweighted lever 22,against a baffle member 33 provided for defining an opening through the separating wall 3 so as to discharge the ice cubes made in the vessel 2.
  • the projecting portion will abut again against the baffle member 33 to bring it to its closure position.
  • the ice making apparatus further comprises an electronic card electric circuit for controlling the high or low voltage power circuit and the auxiliary circuit,which is provided with detecting sensors 13 for detecting the presence of water in the water tank 5,as well as with a display-acoustic assembly 40 arranged on the top cover member 41 closing the bearing frame 1.
  • the operation of the ice making apparatus is such that the ice cubes are made as the ice making tank 21 is arranged in its raised position,by immersing the lugs 16 into said tank.
  • the tank 23 is in its lowered position,while the tank 21 is in its raised position.
  • the tank 23 will be gradually emptied;as the weight of this tank 23 becomes smaller than that of the tank 21,said tank 23 will be upward displaced,while the tank 21 will be lowered by gravity in such a way as to cause the baffle member 33 to be tilted,with a consequent opening toward the ice vessel.
  • variable weight small tank 23 will be arrang­ed above the small tank 21,thereby recovering the water level inside the tank 21.
  • a position sensor detects the upward position of the variable weight tank 23 and will actuate,for a time adjustable from 30 to 90s,the hot gas electric or solenoid valve to cause the ice cubes to detach from the lugs 16,fall onto the baffle member 33 and enter the ice vessel or tank.
  • the pump 11 will be actuated again for supplying water to the tank 23 to a level unable of operating the siphon member 25.
  • the lugs 16 will be immersed again in the tank 21,where water is present,thereby starting a new ice making cycle.
  • the ice making apparatus will continue to operate to fill the ice vessel in such a degree that the baffle member 33 will be prevented from recovering to its home position,thereby preventing the tank 21 to raise;thus the intermediate position sensor of the tanks will stop the apparatus.
  • a further safety stop of the ice making apparatus is caused by the sensor 13,arranged in the tank 5,which prevents the apparatus from operating as water is lacking.
  • This driving is simply obtained by exploiting the weight variation of the counterweight tank, by actuating a siphon member.
