Showcase

Abstract

A showcase designed to simultaneously store commodities to be cooled at different temperatures has a showcase body having an opening at least in its front, a commodity storage section provided in the showcase body, a first air passage having an air inlet at a lower end of the opening, a blower for causing air to flow from the air inlet into the first air passage, a cooler for cooling the air flowing into the first air passage, a plurality of second air passages formed so as to branch off from the first air passage and extend toward the opening, each second air passage having an air outlet at its end, and a flow rate adjustment mechanism for adjusting the flow rates of air flowing from the first air passage into at least one of the second air passages, whereby the flow rates of air flowing into the second air passages are respectively adjusted to different values.

1 . A showcase comprising: 
 a showcase body having an opening at least in its front;    a commodity storage section provided in the showcase body;    a first air passage having an air inlet at a lower end of the opening;    a blower for causing air to flow from the air inlet into the first air passage;    a cooler for cooling the air flowing into the first air passage;    a plurality of second air passages formed so as to branch off from the first air passage and extend toward the opening, each second air passage having an air outlet at its end; and    a flow rate adjustment mechanism for adjusting the flow rates of air flowing from the first air passage into at least one of the second air passages.    
   
   
       2 . The showcase according to  claim 1 , wherein: 
 the flow rate adjustment mechanism includes a plurality of communication holes for communication between the first air passage and the second air passage, and a closing plate for closing part of the plurality of communication holes.    
   
   
       3 . The showcase according to  claim 2 , further comprising: 
 a communication hole opening/closing mechanism for moving the closing plate in a direction for closing part of the communication holes and in a direction for opening the part of the communication holes.    
   
   
       4 . The showcase according to  claim 3 , wherein: 
 the communication hole opening/closing mechanism includes an elongated hole provided in a member forming the first air passage, and a fixing member connected to the closing plate through the elongated hole and capable of being fixed at a predetermined position in the elongated hole to fix the closing plate at a predetermined position.    
   
   
       5 . The showcase according to  claim 1 , wherein: 
 the flow rate adjustment mechanism includes at least one communication hole for communication between the first air passage and the second air passage, and a closing plate for closing at least part of the communication hole.    
   
   
       6 . The showcase according to  claim 5 , further comprising: 
 a communication hole opening/closing mechanism for moving the closing plate in a direction for closing the communication hole and in a direction for opening the communication hole.    
   
   
       7 . The showcase according to  claim 6 , wherein: 
 the communication hole opening/closing mechanism includes an elongated hole provided in a member forming the first air passage, and a fixing member connected to the closing plate through the elongated hole and capable of being fixed at a predetermined position in the elongated hole to fix the closing plate at a predetermined position.
