Abstract
The invention provides a vacuum heat insulating plate and a household appliance. The vacuum heat insulating plate comprises a core material, N layers of obstructing films and N-1 layers of vacuum buffering layers. The N layers of obstructing films surround the core material, and the obstructing film on the innermost layer wraps the core material; and each vacuum buffering layer is arranged between every two corresponding adjacent obstructing films, wherein N is a positive integer larger than or equal to 2, and the obstructing films are all sealed in vacuum. According to the vacuum heat insulating plate provided by the scheme, the vacuum buffering layers are added outside the core material, the vacuum degree of the vacuum buffering layers is the same as or similar to that of the core material, and therefore outside gas needs to pass through the obstructing film on the outermost layer first and then permeates into the vacuum buffering layers, then the outside gas permeates into the core material area from the vacuum buffering layers, the vacuum buffering layers play a role of weakening the effect of the core material area and the outside pneumatic pressure difference, the speed at which the outside gas permeates into the core material area is decreased, and therefore the service life of the vacuum heat insulating plate is prolonged.
