ABSTRACT:
A toy oven has a heating compartment accessible through an aperture in a front wall of a housing of the oven. A door is provided which is manually movable to close off the aperture. IN one embodiment, the door is slidably mounted and in another embodiment it is pivotally mounted. A mechanical interlock engages the door to prevent it from opening if the electrical power switch is on. Another mechanical interlock prevents the door from opening when the heating compartment is at a high temperature. The oven is thus safe to use by children in normal play. A fan may be provided to cool the heating compartment when the power switch is turned off and is thereafter automatically turned off after a predetermined time or when the temperature in the heating compartment falls to a safe level. A timer may also be provided to automatically switch power off after a predetermined time of inactivity.
