Abstract
A kiln has a control box pivotably coupled to an oven portion via a hinge at a lower end of the control box so that the control box can pivot about the hinge from a closed position adjacent the oven portion to an open position where an upper end of the control box is separated from the oven portion. The control box houses electronic controller components. A chimney portion is attached to the oven portion and is separated from the upper end of the control box when the control box is in the open position. The control box pivots about the hinge along a generally horizontal axis. A linkage is coupled between the control box and the oven portion to limit the pivotal movement range of the control box at the open position.
Claims20
A kiln, comprising:
- an oven portion including an oven sidewall;
- a control box including sidewalls forming a protective housing and electronic controller components contained at least partially within the protective housing, the protective housing including an access opening through which maintenance actions can be performed on the electronic controller components;
- the control box being coupled to the oven portion for movement to a closed position in which the access opening is disposed in close proximity to the oven sidewall and maintenance access through the access opening is at least partially blocked by the oven sidewall, and to a maintenance position in which the access opening is spaced from the oven sidewall by a spacing distance that is sufficient to allow maintenance actions to be performed through the access opening;
- and
- a thermal insulation assembly attached to and spaced from the oven portion, the thermal insulation assembly providing a thermal shield between the oven sidewall and the electronic controller components when the control box is in the closed position.

A kiln, comprising:
- an oven portion including an oven sidewall;
- a control box including sidewalls forming a protective housing and electronic
- controller components contained at least partially within the protective housing, the control box being releasably secured in latched engagement with the oven portion in a closed position in which the control box is disposed in close proximity to the oven sidewall and access to the electronic controller components is restricted, and releasable from latched engagement to permit movement of the protective housing away from the oven sidewall to a maintenance position in which the access opening is spaced from the oven sidewall by a spacing distance that is sufficient to allow maintenance actions to be performed through the access opening;
- and
- a hinge assembly connecting the control box to the oven portion, the hinge assembly supporting drop-down pivotal movement of the control box from the closed position to the maintenance position.
2 more elements
A kiln, comprising:
- an oven portion having walls defining an oven space;
- a control box including sidewalls forming a protective housing and electronic controller components contained at least partially within the protective housing, the protective housing including first and second end portions and an access opening disposed between the first and second end portions through which maintenance actions can be performed on the electronic controller components;
- and
- a hinge assembly connecting the first end portion of the protective housing to the oven portion, the hinge assembly supporting pivotal movement of the control box to a closed position in which the second end portion of the control box is disposed closely adjacent the oven portion, and to a drop-down maintenance position in which the second end portion of the protective housing is angularly displaced and separated from the oven portion and the sidewalls of the control box slope transversely relative to the kiln sidewall;
- and
- a linkage coupled to the control box and the oven portion for limiting drop-down movement range of the control box relative to the oven portion.

- and
- means coupled to the control box and the oven portion for limiting drop-down movement range of the control box relative to the oven portion.
