Abstract
The ash pan is a composite ash pan and includes an outer pan formed of stainless steel and an inner pan, formed of aluminum, adapted to be removably inserted into the outer pan. The inner pan has a raised central portion for separating and supporting the solid waste from the liquid waste. In the preferred embodiment, the raised central portion extends up to a height about equal to that of the height of the surrounding wall of the inner pan and the height of the surrounding wall of the inner pan is nearly equal to the height of the surrounding wall of the outer pan.

In an incinerator toilet having an incinerator chamber comprising a chamber means with an opening formed therethrough, heating means located in said opening of said chamber means, and a removable ash pan located below said chamber means, said ash pan comprising:
- an outer pan formed of stainless steel and comprising an outer annular side wall with a bottom wall and,
- an inner pan formed of aluminum adapted to be removably inserted into said outer pan,
- said inner pan being separate from said outer pan,
- said inner pan comprising an annular surrounding side wall, an annular lower wall portion extending inwardly from the lower end of said annular surrounding side wall and a raised central portion spaced inwardly of said annular surrounding side wall,
- said raised central portion comprising an annular inner side wall having a lower end extending upwardly from said annular lower wall portion such that said annular inner side wall is spaced from said annular surrounding side wall and a central upper wall forming an upper platform connected to the upper end of said annular inner side wall,
- the outside surface of said annular surrounding side wall of said inner pan being adapted to engage the inside surface of said outer annular side wall of said outer pan when said inner pan is inserted into said outer pan,
- the outside surface of said annular lower wall portion of said inner pan being adapted to engage at least a portion of the bottom wall of said outer pan next to its outer annular side wall when said inner pan is inserted into said outer pan.
In an incinerator toilet having an incinerator chamber comprising a chamber means with an opening formed therethrough, heating means located in said opening of said chamber means, and a removable ash pan located below said chamber means, said ash pan comprising:
- an outer pan formed of stainless steel and comprising an outer annular side wall with a bottom wall and,
- an inner pan formed of aluminum adapted to be removable inserted into said outer pan,
- said inner pan being separate from said outer pan,
- said inner pan comprising an annular surrounding side wall, an annular lower wall portion extending inwardly from the lower end of said annular surrounding side wall and a raised central portion spaced inwardly of said annular surrounding side wall,
- said raised central portion comprising an annular inner side wall having a lower end extending upwardly from said annular lower wall portion such that said annular inner side wall is spaced from said annular surrounding side wall and a central upper wall forming an upper platform connected to the upper end of said annular inner side wall,
- the outside surface of said annular surrounding side wall of said inner pan being adapted to engage the inside surface of said outer annular side wall of said outer pan when said inner pan is inserted into said outer pan,
- the outside surface of said annular lower wall portion of said inner pan being adapted to engage at least a portion of the bottom wall of said outer pan next to its outer annular side wall when said inner pan is inserted into said outer pan,
- the height of said annular surrounding side wall of said inner pan being greater than one half of the height of said outer annular side wall of said outer pan such that when said inner pan is inserted into said outer pan, the upper end of said annular surrounding side wall of said inner pan extends upward to a position near the upper end of said outer annular side wall of said outer pan,
- the height of said raised portion of said inner pan being about the same as the height of said annular surrounding side wall of said inner pan relative to said annular lower wall portion.
In an incinerator toilet having an incinerator chamber comprising a chamber means with an opening formed therethrough, heating means located in said opening of said chamber means, and a removable ash pan located below said chamber means, said ash pan comprising:
- an outer pan formed of stainless steel and comprising an outer annular side wall with a bottom wall and,
- an inner pan formed of aluminum adapted to be removably inserted into said outer pan,
- said inner pan being separate from said outer pan,
- said inner pan comprising an annular surrounding side wall, an annular lower wall portion extending inwardly from the lower end of said annular surrounding side wall and a raised central portion spaced inwardly of said annular surrounding side wall;
- said raised central portion comprising an annular inner side wall having a lower end extending upwardly from said annular lower wall portion such that said annular inner side wall is spaced from said annular surrounding side wall and a central upper wall forming an upper platform connected to the upper end of said annular inner side wall,
- the outside surface of said annular lower wall portion of said inner pan being adapted to engage at least a portion of the bottom wall of said outer pan when said inner pan is inserted into said outer pan,
- the upper end of said annular surrounding side wall of said inner pan being located below the upper end of said outer annular side wall of said outer pan when said inner pan is inserted into said outer pan.
In an incinerator toilet having an incinerator chamber comprising a chamber means with an opening formed therethrough, heating means located in said opening of said chamber means, and a removable ash pan located below said chamber means, said ash pan comprising:
- an outer pan formed of stainless steel and comprising an outer annular side wall with a bottom wall and,
- an inner pan formed of aluminum adapted to be removably inserted into said outer pan,
- said inner pan comprising an annular surrounding side wall, an annular lower wall portion extending inwardly from the lower end of said annular surrounding side wall and a raised central portion spaced inwardly of said annular surrounding side wall,
- said raised central portion comprising an annular inner side wall having a lower end extending upwardly from said annular lower wall portion such that said annular inner side wall is spaced from said annular surrounding side wall and a central upper wall forming an upper platform connected to the upper end of said annular inner side wall,
- the outside surface of said annular lower wall portion of said inner pan being adapted to engage at least a portion of the bottom wall of said outer pan when said inner pan is inserted into said outer pan,
- the height of said annular surrounding side wall of said inner pan being greater than one half of the height of said outer annular side wall of said outer pan such that when said inner pan is inserted into said outer pan, the upper end of said annular surrounding side wall of said inner pan extends upward to a position near but below the upper end of said outer annular side wall of said outer pan,
- the height of said raised portion of said inner pan being about the same as the height of said annular surrounding side wall of said inner pan relative to said annular lower wall portion.
