Insulation structure for appliances
DCFirst Claim
1. In combination:
- an insulation panel arranged into four sections comprising;
a first layer of enclosing material having a configuration which approximates the four sections of said panel;
a second layer of enclosing material having a configuration which approximates the four sections of said panel; and
an intermediate layer of insulation material disposed between said first and second layers of enclosing material; and
an automatic dishwasher wherein said insulation panel is formed over and around the exterior of said dishwasher such that each section of said insulation panel is applied against a different surface of said dishwasher.

Abstract
An insulation panel for an appliance for reducing one or more undesirable side effects due to the operation of the appliance such as noise, vibration and heat includes a first layer of enclosing material such as polyethylene or polypropylene which has greater tear resistance and configuring this first layer of enclosing material to a size and shape based upon the appliance and the area of the appliance to be covered. Next, a second layer of similar enclosing material is selected and configured so as to having a matching peripheral edge or contour with the first layer. Ultimately these two layers of enclosing material are joined together around their peripheral edges so as to define and completely enclose an interior cavity. Into this interior cavity a blanket of insulating material is dispersed of a generally uniform blanket thickness. In certain applications, the insulating material includes a binder so that the insulating material will not shift or settle relative to the enclosed cavity. The particular insulating material may either be selected for acoustical insulation, vibration dampening and/or thermal insulation. A singular purpose of the insulating material may be desired or multiple uses may be desired in which case part of the enclosed cavity may include acoustical insulation and part of the enclosed cavity may include vibration-dampening material.

2. In combination:
an insulation panel comprising; a first layer of enclosing material having a generally block T-shaped configuration; and a second layer of enclosing material having a generally block T-shaped configuration; and an intermediate layer of insulation material disposed between said first and second layers of enclosing material; and
an automatic dishwasher wherein said insulation panel is formed over and around the exterior of said dishwasher so as to apply insulation to four different surfaces of said dishwasher.

3. In combination:
-
an under-the-counter, in-cabinet automatic dishwasher; and an insulation panel cooperatively applied to said dishwasher for noise reduction, said insulation panel comprising; a first layer of enclosing material having a peripheral edge of a predetermined shape; a second layer of enclosing material having a peripheral edge of a predetermined shape which is substantially the same as the shape of the peripheral edge of said first layer of enclosing material; an intermediate layer of insulation material disposed between said first and second layers of enclosing material; a panel of insulation material secured to the exterior surface of said first layer of enclosing material; and said first and second layers being joined together along their peripheral edges so as to define an enclosed cavity, said intermediate layer of insulation material being retained in said enclosed cavity.

4. In combination:
-
an insulation panel comprising; a first layer of enclosing material having a peripheral edge of predetermined shape; a second layer of enclosing material having a peripheral edge of predetermined shape which is substantially the same as the shape of the peripheral edge of the first enclosing layer; and an intermediate layer of insulation material disposed between the first and second layers of enclosing material; said first and second layers of enclosing material being joined along their peripheral edges so as to define a substantially airtight cavity, said intermediate layer of insulation material being retained in said cavity; and an automatic dishwasher wherein said insulation panel is formed over and around the exterior of said dishwasher so as to apply insulation to four different surfaces of said dishwasher.
