Icemaker

Abstract

The icemaker comprises an evaporator equipped with a plurality of open cells for the formation of ice elements, a sprayer for spraying water into the cells, a tank for collecting the water not transformed into ice in the cells, the sprayer having an element for occluding the cells equipped with a plurality of calibrated holes, each for access to a corresponding cell and a plurality of nozzles, each engaged in a corresponding access hole for the injection of water into a corresponding cell, the sprayer being supported by a support in a movable manner between an opening position and a closing position of the cells by means of the occlusion element, a kinematic mechanism for moving said support also being provided externally to said collection tank.

1 . An icemaker comprising an evaporator equipped with a plurality of open cells for the formation of ice elements, a sprayer for spraying water into the cells, a tank for collecting the water not converted into ice in the cells, characterized in that said sprayer has an element for occluding said cells equipped with a plurality of calibrated holes each for access to a corresponding cell and a plurality of nozzles each engaged in a corresponding access hole for the injection of water into a corresponding cell, said sprayer being supported below said evaporator by a support in a movable way between an opening position and a closing position of said cells by means of said occlusion element and being removable from a window on a front side of said collecting tank, a kinematic mechanism for moving said support also being provided externally to said collection tank. 
     
     
         2 . The icemaker according to  claim 1 , characterized in that said support has guides for extracting and introducing said sprayer. 
     
     
         3 . The icemaker according to  claim 1 , characterized in that between each injection nozzle and the corresponding hole there is a gap for the outlet of the water not transformed into ice. 
     
     
         4 . The icemaker according to  claim 3 , characterized in that said sprayer has a drainage channel for draining the water not transformed into ice towards the inside of said collection tank. 
     
     
         5 . The icemaker according to  claim 4 , characterized in that said drainage channel is provided on an internal wall of said sprayer where said nozzles are also provided. 
     
     
         6 . The icemaker according to  claim 5 , characterized in that said access holes are provided on a first external wall of said sprayer structurally independent and separated from said internal wall. 
     
     
         7 . The icemaker according to  claim 1 , characterized in that each injection nozzle is positioned coaxially to the corresponding hole. 
     
     
         8 . The icemaker according to  claim 1 , characterized in that in said closing position each injection nozzle is oriented along a central axis of the corresponding cell. 
     
     
         9 . The icemaker according to  claim 1 , characterized in that each cell has a corresponding hole for the passage of air which is offset from the direction along which the corresponding nozzle is oriented in said closing position. 
     
     
         10 . The icemaker according to  claim 1 , characterized in that each nozzle has a tip in an intermediate position between the ends of the corresponding access hole. 
     
     
         11 . The icemaker according to  claim 1 , characterized in that said sprayer has a water collector. 
     
     
         12 . The icemaker according to  claim 11 , characterized in that said water collector is delimited by said internal wall and by a second external wall of said sprayer structurally independent and separated from said internal wall. 
     
     
         13 . The icemaker according to  claim 12 , characterized in that said internal wall has a releasable connection means with said first and second external wall. 
     
     
         14 . The icemaker according to  claim 1 , characterized in that said support is configured as an oscillating rocker that has a first lever arm that supports said sprayer and a second lever arm for starting the movement from said kinematic mechanism. 
     
     
         15 . The icemaker according to  claim 14 , characterized in that said kinematic mechanism comprises a first motorized rod constrained in translation and a second rod having a first end constrained to said first rod and a second end constrained to said second lever arm. 
     
     
         16 . The icemaker according to  claim 1 , characterized in that it comprises a recirculation circuit for recirculating the water collected in said collection tank having a recirculation pump positioned outside said collection tank.
