Refrigeration circulation apparatus of a playing machine

Abstract

The present invention relates to a refrigeration circulation apparatus of a playing machine, including a refrigerator and a baffle. The baffle is mounted in the frame of a playing machine. The refrigerator includes an evaporator mounted on one end of the baffle, and extended to the upper side and the lower side of the baffle. The evaporator of the refrigerator is mounted in a first passage. A plurality of fans are mounted under the first passage. When the refrigeration circulation starts operation, the fans located under the first passage start to draw the air under the baffle. The heat is absorbed by the evaporator of the refrigerator, and the air is then blown out through the first passage to be returned to a position under the baffle through a second passage. Thus, the air circulates continuously between the upper side and the lower side of the baffle through the evaporator of the refrigerator, so that the cold air can be used for refrigerating food placed on the upper surface of the baffle.

What is claimed is:  
     
         1 . A refrigeration circulation apparatus of a playing machine, comprising: 
 a frame of a playing machine;    a baffle, mounted in the frame of the playing machine, thereby dividing the frame into an upper side and a lower side, the baffle having a first end defining a first passage, and a second end defining a second passage;    a refrigerator, including an evaporator, a compressor, and a condenser, which are connected by a pipe, the evaporator mounted in the first passage of the baffle; and    a plurality of fans, mounted under the first passage of the baffle;    wherein, when the fans located under the first passage of the baffle start operation, air under the baffle is drawn, to pass through the evaporator of the refrigerator to be cooled, cold air is blown from holes of the first passage, to enter the second passage through an upper surface of the baffle, whereby the cold air is returned to a position under the baffle, and the cold air circulates continuously between an upper portion and a lower portion of the baffle, for refrigerating food placed on the upper portion of the baffle.    
     
     
         2 . The refrigeration circulation apparatus of a playing machine as claimed in  claim 1 , wherein the first passage is provided with a first cover extending between the upper side and the lower side of the baffle, the first cover has a portion extending to the upper side of the baffle and defining a plurality of holes, when the fans start operation, air under the baffle is drawn to enter the first cover, the air passes through the evaporator of the refrigerator to be cooled, and is blown toward the second passage through the holes of the first cover.  
     
     
         3 . The refrigeration circulation apparatus of a playing machine as claimed in  claim 1 , wherein the second passage is provided with a second cover extending between the upper side and the lower side of the baffle, the second cover defines a plurality of holes, when the cold air is blown outward from the holes of the first cover, the cold air enters the holes of the second cover located above the baffle, and is drained through the holes of the second cover located under the baffle.  
     
     
         4 . The refrigeration circulation apparatus of a playing machine as claimed in  claim 1 , wherein the first cover has a lower end provided with a collecting chute, the collecting chute has a lower portion connected to a flow guide pipe, water condensed by the evaporator is collected in the collecting chute, and is drained outward from the playing machine through the flow guide pipe.  
     
     
         5 . The refrigeration circulation apparatus of a playing machine as claimed in  claim 1 , wherein the refrigerator is provided with a temperature control device for adjusting a refrigeration temperature, and when reaching a preset temperature, the compressor stops operation for saving energy.  
     
     
         6 . The refrigeration circulation apparatus of a playing machine as claimed in  claim 1 , wherein the frame of the playing machine is provided with an article falling opening, the article falling opening is provided with a catch plate, when a user operates the playing machine, the catch plate is opened for allowing falling of food, when the user stops operating the playing machine, the catch plate is closed, thereby preventing the cold air from leaking through the article falling opening to the ambient environment.  
     
     
         7 . The refrigeration circulation apparatus of a playing machine as claimed in  claim 1 , wherein a heat insulating baffle is mounted under the baffle, thereby preventing the cold air from absorbing heat of an environment.  
     
     
         8 . The refrigeration circulation apparatus of a playing machine as claimed in  claim 6 , wherein operation of the catch plate is controlled by a motor and a plurality of linking levers.  
     
     
         9 . The refrigeration circulation apparatus of a playing machine as claimed in  claim 1 , wherein the baffle is provided with a plurality of through holes, when the cold air is blown outward through the holes of the first passage, the cold air flows through the through holes to a position located under the baffle, thereby enhancing the refrigeration efficiency.
