Oven with temperature balancing

An oven comprising,

• a chamber wherein heated air is circulated,
• said chamber having a first opening to the ambient environment at a first end thereof and a second opening to the ambient environment at a second end thereof,
• means for measuring a physical parameter of the ambient environment at each end of said chamber;
• and
• means for adjusting the air circulation in at least one end of said chamber to compensate for the effects of said ambient environment on said heated air in the chamber,
• said means for adjusting including shutter means positioned adjacent at least one end of the chamber and operative to control the flow of said heated air which is circulated in said chamber, and
• means for moving said shutter means connected to said means for measuring in order to produce a predetermined relationship between the measured physical parameter of the ambient environment at each end of said chamber by controlling the flow of said heated air.

An oven comprising,

• a heating chamber having first and second ends,
• measuring means at at least one of said first and second ends,
• said measuring means operative to measure at least one of the parameters of temperature and air flow at the respective ends;
• air flow control means disposed adjacent said respective end, and
• control means connected to said measuring means and to said air flow control means so that said air flow control means is manipulated in response to the parameter measurement by said measuring means.

An oven comprising,

• a heating chamber having first and second ends,
• air moving means mounted at said heating chamber,
• air flow control means mounted in said heating chamber to control the air flow caused in said heating chamber by said air moving means,
• controller means connected to said air flow control means to control the operation thereof as a function of air flow at at least one of said first and second ends of said heating chamber.

An oven comprising,

• chamber means having first and second ends,
• said chamber means having first and second openings to the ambient environment at said first and second ends, respectively, and
• circulation means for causing heated air to be circulated within said chamber means,
• means for controlling the air circulation in said chamber means in order to compensate for the effects of said ambient outside environment on said heated air in said chamber means,
• said means for controlling the air circulation in said chamber means includes means for mixing a portion of heated air at each of said first and second ends of said chamber means with the heated air at the other one of said first and second ends of said chamber means,
• said means for controlling the air circulation includes first and second shutter means positioned in the path of a portion of the heated air at said first and second ends, respectively, of said chamber means, and
• at least one of said first and second shutter means comprises a slidable shutter means.

An oven comprising,

• chamber means having a first end and a second end,
• said chamber means having a first opening to the ambient environment at said first end and a second opening to the ambient environment at said second end,
• means for controlling the air circulation in said chamber means in order to negate the effects of said ambient outside environment on said heated air in said chamber means and to maintain a uniform temperature within said chamber means,
• means for mixing together a portion of the heated air within said chamber means from each of said first and second ends of said chamber means and supplying the mixed air to said circulation means, and
• temperature measurement means for measuring the air temperature at each end of said chamber means.
