Abstract
The invention provides an electric oven which comprises an oven body, a heating unit, an exhaust device, a control switch and a temperature control device. The temperature control device is used for detecting temperature in a cavity and controlling work of the exhaust device according to the temperature in the cavity when the heating unit stops heating. When the control switch is turned on and the electric oven is started, the exhaust device is started at the same time, so air in the cavity can be circulated effectively and harmful gas and odors in the cavity can be dissipated timely through the exhaust mode. When the control switch is turned off and the heating unit does not work, the exhaust device continues to work through the temperature control device until temperature in the oven decreases to a preset temperature of the temperature control device, and namely the exhaust device continues to work through the temperature control device until the temperature in the oven decreases to the preset temperature of the temperature control device when the heating unit stops heating and the temperature in the cavity is higher than the preset temperature. Therefore, cooling of the interior of the electric oven can be accelerated through the exhaust mode, and the service life of the electric oven is prolonged.
