Definitions

• the invention relates to a convection oven according to the preamble of the first claim.
• the invention is based on the object of taking measures in a convection oven according to the preamble of the first claim, by means of which simple operations to prevent incorrect operation when selecting the operating mode.
• a switching device can be used to prevent the recirculation fan from being operated at an increased speed below a predetermined temperature value.
• the steam generator can only be switched on via the associated switching device when a specific, predetermined temperature value has been set on the temperature controller.
• the undesirably high amount of air is switched on at a low temperature or the insufficient, low amount of air is switched on at the circulating air fan at a high temperature.
• the latter can cause the air-cooled muffle heating element to burn through, while in the first case the cooking result can be poor. Inapplicable program variation options are thus excluded and increased ease of use when selecting the operating mode is achieved.
• the temperature controller or its setting element in particular the axis of rotation of a temperature controller for controlling the heating element, can be assigned at least one operating mode function switch which e.g. can be designed as a limit switch and is actuated or changed its switching position only after a predetermined adjustment path or angle of rotation of the temperature controller. Then, for example, the increased speed of the circulating air blower will be automatically switched on after this predetermined adjustment path.
• operating mode function switch e.g. can be designed as a limit switch and is actuated or changed its switching position only after a predetermined adjustment path or angle of rotation of the temperature controller. Then, for example, the increased speed of the circulating air blower will be automatically switched on after this predetermined adjustment path.
• the temperature controller prefferably be assigned an electrical setting resistor as the setpoint generator, the resistance value of which is changed via the adjustment path.
• This change in resistance or the respectively set resistance value is recorded in a connected electrical evaluation circuit and is preferably converted into a switching signal for the muffle heating element in comparison with a temperature-dependent resistance value.
• this resistance value is also compared with a fixed operating mode switching value, which e.g. corresponds to the value at which the speed changeover and / or the connection or disconnection of the steam generator is to take place.
• the switching device controlled in this way thus leads to the automatic switching of the operating mode.
• a separate, adjustable resistor can be coupled to the temperature controller for the operating mode switching value.
• a switch circuit board preferably a step switch, can also be coupled to the setting element of the temperature controller, by means of which a change in the operating mode is set depending on the adjustment path.
