Fridge-freezer

Abstract

A fridge-freezer equipped with a deodorizing unit which has a filter including photocatalyst and a light emitting unit including an LED as a light source mounted on a substrate. The fridge-freezer is designed to solve problems posed by conventional fridge-freezers. One of the problems is that in the case of using a glass-tube type lamp such as a black light or a cold cathode tube as the light source, the light source becomes large in size which requires a large space for installation. This does not allow the deodorizing unit to be installed in the compartments in the refrigerator. Another problem is that the deodorizing unit was not designed to be safe for food in case that part of the deodorizing unit is damaged to give harmful damage to food.

What is claimed is:  
     
         1 . A fridge-freezer comprising a deodorizing unit; 
 wherein the deodorizing unit includes, 
 a filter having a photocatalyst, and  
 a light emitting unit for emitting ultraviolet rays.  
   
     
     
         2 . The fridge-freezer of  claim 1 , wherein the light emitting unit has an LED (Light Emitting Diode) for emitting the ultraviolet rays.  
     
     
         3 . The fridge-freezer of  claim 1 , wherein the filter further includes an absorption material.  
     
     
         4 . The fridge-freezer of  claim 1 , wherein the deodorizing unit has a solid structure with a fixed distance kept between the filter and the light emitting unit.  
     
     
         5 . The fridge-freezer of  claim 1 , further comprising a damper unit; 
 wherein the deodorizing unit and the damper unit have a solid structure.    
     
     
         6 . The fridge-freezer of  claim 1 , wherein the deodorizing unit includes a transparent case which covers the light emitting unit and transmits the ultraviolet rays.  
     
     
         7 . The fridge-freezer of  claim 6 , wherein the transparent case is drip-proof.  
     
     
         8 . The fridge-freezer of  claim 6 , wherein the transparent case has a lens in part.  
     
     
         9 . The fridge-freezer of  claim 2 , wherein the light emitting unit includes a reflecting material which is placed around the LED.  
     
     
         10 . The fridge-freezer of  claim 1 , comprising a plurality of flow-rate regulators for regulating a flow rate of air in a cool air duct in order to control temperatures; 
 wherein a plurality of deodorizing units corresponding to the plurality of flow-rate regulators is placed in the cool air ducts.    
     
     
         11 . The fridge-freezer of  claim 10 , wherein the plurality of flow-rate regulators are damper units.
