Abstract

A vacuum insulated structure for an appliance includes a trim breaker defining a first groove and a second groove. A first panel is disposed within the first groove and coupled to the trim breaker. A second panel is disposed within the second groove and coupled to the trim breaker. An adhesive is disposed within the first and second grooves and coupled to the first and second panels, respectively, wherein the trim breaker has a heat deflection temperature of at least 100° Celsius.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A vacuum insulated structure for an appliance, comprising:
 a trim breaker defining a first groove and a second groove;   a first panel disposed within the first groove and coupled to the trim breaker;   a second panel disposed within the second groove and coupled to the trim breaker; and   an adhesive disposed within the first and second grooves and coupled to the first and second panels, respectively, wherein the trim breaker has a heat deflection temperature of at least 100° Celsius.   
     
     
         2 . The vacuum insulated structure of  claim 1 , wherein the trim breaker comprises a glycol-modified polyethylene terephthalate copolyester. 
     
     
         3 . The vacuum insulated structure of  claim 2 , wherein the trim breaker comprises mica flakes doped in the glycol-modified polyethylene terephthalate copolyester. 
     
     
         4 . The vacuum insulated structure of  claim 1 , wherein the trim breaker has a nitrogen transmission rate of less than 2 cc·mm/m 2 /day/atm. 
     
     
         5 . The vacuum insulated structure of  claim 4 , wherein the nitrogen transmission rate is between 0.05 and 1.2 cc·mm/m 2 /day/atm. 
     
     
         6 . The vacuum insulated structure of  claim 1 , wherein the trim breaker has a water vapor transmission rate of less than 25 cc·mm/m 2 /day/atm. 
     
     
         7 . The vacuum insulated structure of  claim 6 , wherein the water vapor transmission rate is between 0.07 and 1.8 cc·mm/m 2 /day/atm. 
     
     
         8 . The vacuum insulated structure of  claim 1 , wherein the trim breaker has an oxygen transmission rate of less than 2.5 cc·mm/m 2 /day/atm. 
     
     
         9 . The vacuum insulated structure of  claim 1 , wherein the trim breaker has an oxygen transmission rate of between 1 and 20 cc·mm/m 2 /day/atm. 
     
     
         10 . A vacuum insulated structure for a refrigerator, comprising:
 a trim breaker defining a first groove and a second groove spaced from one another defining a cavity therebetween;   a first panel disposed within the first groove and coupled to the trim breaker;   a second panel disposed within the second groove and coupled to the trim breaker; and   an adhesive disposed within the first and second grooves and coupled to the first and second panels, respectively, wherein the trim breaker comprises a polyethylene terephthalate copolyester resin and has a water vapor transmission rate of less than 25 cc·mm/m 2 /day/atm.   
     
     
         11 . The vacuum insulated structure of  claim 10 , wherein the polyethylene terephthalate copolyester resin includes glycol. 
     
     
         12 . The vacuum insulated structure of  claim 10 , wherein the trim breaker has a heat deflection temperature of at least 100° Celsius. 
     
     
         13 . The vacuum insulated structure of  claim 10 , wherein the trim breaker has a nitrogen transmission rate of less than 2 cc·mm/m 2 /day/atm. 
     
     
         14 . The vacuum insulated structure of  claim 13 , wherein the nitrogen transmission rate is between 0.05 and 1.2 cc·mm/m 2 /day/atm. 
     
     
         15 . The vacuum insulated structure of  claim 10 , wherein the water vapor transmission rate is between 0.07 and 1.8 cc·mm/m 2 /day/atm. 
     
     
         16 . The vacuum insulated structure of  claim 10 , wherein the trim breaker has an oxygen transmission rate of less than 2.5 cc·mm/m 2 /day/atm. 
     
     
         17 . The vacuum insulated structure of  claim 10 , wherein the trim breaker has an oxygen transmission rate of between 1 and 20 cc·mm/m 2 /day/atm. 
     
     
         18 . A vacuum insulated panel for a refrigerator, comprising:
 a trim breaker defining a first groove and a second groove spaced from one another defining a cavity therebetween;   a liner disposed in the first groove and coupled to the trim breaker;   a wrapper disposed in the second groove and coupled to the trim breaker; and   an adhesive disposed within the first and second grooves and coupled to the first and second panels, respectively, wherein the trim breaker comprises a glycol-modified polyethylene terephthalate copolyester resin and has a heat deflection temperature of at least 100° Celsius.   
     
     
         19 . The vacuum insulated panel of  claim 18 , wherein the trim breaker comprises mica flakes doped in the glycol-modified polyethylene terephthalate copolyester. 
     
     
         20 . The vacuum insulated panel of  claim 18 , wherein the trim breaker has a water vapor transmission rate of less than 25 cc·mm/m 2 /day/atm.
