Refrigerating apparatus and storge device using the same

Abstract

A refrigerating apparatus is provided with a cooling unit whose height is greater than width when installed; and a defrosting device for defrosting frost formed on the cooling unit by heat, the defrosting device being in a straight pipe form, wherein the defrosting device is provided in a vertical direction on a side of the cooling unit. By providing the defrosting device in a straight pipe form in the vertical direction on the side of the cooling unit that is long in a longitudinal direction, it is possible to increase the length of the defrosting device and to lower a surface temperature of the defrosting device. Further, as the defrosting device is long, an amount of heat generation is large and defrosting efficiency is high. Moreover, it is possible to manufacture the defrosting device at a low cost as the defrosting device is in a straight pipe form.

1 . A refrigerating apparatus, comprising:
 a cooling unit whose height is greater than width when installed; and   a defrosting device for defrosting frost formed on the cooling unit by heat, the defrosting device being in a straight pipe form, wherein   the defrosting device is provided in a vertical direction on a side of the cooling unit.   
     
     
         2 . The refrigerating apparatus according to  claim 1 , wherein
 the defrosting device includes:
 a glass tube; 
 a wire heater disposed within the glass tube; 
 leads connected to the wire heater; and 
 caps respectively covering openings on both sides of the glass tube. 
   
     
     
         3 . The refrigerating apparatus according to  claim 2 , wherein
 the wire heater includes a heat generating unit in a coiled form that is configured by a metal resistant body, and   a diameter of the metal resistant body is equal to or greater than 0.21 mm.   
     
     
         4 . The refrigerating apparatus according to  claim 2 , wherein
 the wire heater includes a heat generating unit in a coiled form that is configured by a metal resistant body, and   the heat generating unit has at least two types of spiral pitches, and is disposed such that a side with a smaller one of the spiral pitches comes upside.   
     
     
         5 . The refrigerating apparatus according to  claim 2 , wherein
 the wire heater includes a heat generating unit configured by a carbon fiber.   
     
     
         6 . The refrigerating apparatus according to  claim 1 , wherein
 the defrosting device is disposed in a slanted manner such that an upper side of the device is close to the cooling unit and a lower side of the device is gradually spaced away from cooling unit toward downside.   
     
     
         7 . A storage device, comprising:
 a refrigeration cycle including a compressor, a condenser, a decompressor, and an evaporator that are coupled in a circular pattern by piping;   a storage chamber; and   a blower for circulating a cold air that has been cooled by the evaporator in the storage chamber, wherein   the evaporator is used as the refrigerating apparatus according to  claim 1 .
