A rotisserie oven with a self-cleaning mechanism in the form of a lifting wash arm. The wash arm is driven to lift and rotate when washing the oven by the action of the pressure from the wash water used therein. By lifting, the wash arm negates the sealing action of fatty build-up around its base which would otherwise impede its rotation.

Rotisserie oven with lifting wash arm

A self-cleaning rotisserie oven includes a cooking chamber for cooking food product. A rotor is used for supporting and moving a food product in the cooking chamber. A sump is positioned below the cooking chamber that collects water provided to the cooking chamber. A sensor is positioned to detect when the sump is filled to a set level. An inlet valve is configured to control supply of water to the cooking chamber. A controller is configured to carry out a self-cleaning process. The self-cleaning process includes (a) a pre-rinse phase where the controller (i) opens the inlet valve, (ii) closes the inlet valve when the sensor detects that the sump is filled to the set level, and (iii) determines a duration of time that the inlet valve was open during (i), and (b) a later phase during which the controller opens the inlet valve for an amount of time based on the duration of time determined during (a)(iii).

Self-cleaning rotisserie oven

A self-cleaning rotisserie oven includes a cooking cabinet comprising an internal bottom wall, an internal top wall and internal side walls thereby defining a cooking chamber. A self-cleaning system is provided for cleaning the cooking chamber. A convection system includes a heating element and ventilation system configured to heat the cooking chamber. The ventilation system includes a motor, a fan including a fan shaft connected to the motor such that the motor drives the fan and a bushing including a central channel that receives the fan shaft. The central channel includes an inner surface having a variable inner diameter along an axial length of the bushing such that a first portion of the inner surface is near the fan shaft and a second portion of the inner surface is further from the fan shaft than the first portion.
