Abstract
Structure for locking a latching mechanism provided for controlling the opening of a range oven door selectively closing an oven cavity, so as to prevent the opening thereof when the oven cavity is at a high temperature such as during a pyrolytic self-cleaning operation. The locking device includes a thermal sensor which is caused to be disposed in accurate correlated relationship to the oven wall outwardly thereof as a result of a housing associated with the thermal sensor being secured to the oven wall. Resultingly, the sensor is retained in accurate preselected heat transfer association with the oven cavity while being free of exposure to fumes and gases generated in the oven cavity.
Claims12
In a latching mechanism having a latch assembly, locking means for locking the latch assembly, a heat sensor, mounting bracket means for supporting the sensor in the mechanism, and means responsive to the sensor for operating the locking means as a result of the sensor sensing a preselected high temperature of an adjacent wall, the improvement comprising:
- a cover housing said sensor and having a force transfer portion engaging said mounting bracket means;
- and
- means for securing said cover to said adjacent wall with the force transfer portion, as a result of the cover being secured to said wall, urging said mounting bracket means to a preselected disposition relative to said wall to dispose said heat sensor supported by the mounting bracket means in a preselected thermal transfer spaced relationship to said wall for causing operation of the locking means in accurate correlation with the wall temperature.
In a latching mechanism having locking means, a heat sensor mounting bracket means for supporting the sensor in the mechanism, and means responsive to the sensor for operating the locking means as a result of the sensor sensing a preselected high temperature of an adjacent wall, the improvement comprising:
- wall means having a concave portion enclosing said sensor and defining force transfer means for engaging said mounting bracket means, and a securing portion projecting from said concave portion;
- and
- means for securing said securing portion to said wall with the force transfer means as a result of the wall means being secured to said wall urging said mounting bracket means into a preselected abutment with said wall to dispose said heat sensor supported by the mounting bracket means in a preselected thermal transfer spaced relationship to said wall for causing operation of the locking means in accurate correlation with the wall temperature.
