Abstract: An air channel arrangement of a tower fan, arranged for accommodating an air blower therein, includes a housing having an air inlet, an air outlet and an air blower installation space therein, a volute shell and a volute member having a curved surface portion, wherein the volute shell and the curved surface portion of the volute member are arranged on two sides of the air outlet respectively such that, when the air blower is driven to rotate, the airflow is guided to flow through the air channel smoothly, so that the tower fan has excellent air supply efficiency and is able to prevent eddy airflow being formed in in the air channel and reduce working noise of the tower fan.

Abstract: A cooking control method of a cooking apparatus includes steps of heating a cooking chamber of the cooking apparatus to an ambient temperature by a heating unit of the cooking apparatus, detecting the ambient temperature of the cooking chamber, maintaining the ambient temperature of the cooking chamber, maintaining the ambient temperature of the cooking chamber at a predetermined set temperature by controlling the heating unit when the ambient temperature of the cooking chamber reaches the predetermined set temperature, detecting an inner temperature of an inner portion of the cooking object, and controlling the heating unit to heat the cooking chamber to maintain at an appropriate cooking temperature when the inner temperature of the cooking object reaches the appropriate cooking temperature so as to cook the cooking object at the appropriate cooking temperature in the cooking chamber.

Abstract: A power plug includes a shell, an overheating protection module, a first wire, and a second wire. The overheating protection module includes a first pin, a second pin, a thermal circuit breaker, and a protective resistor. The thermal circuit breaker and the protective resistor are connected in parallel. A first end of the protective resistor is connected to one of the first pin or the second pin, and a second end of the protective resistor is connected to one of the first wire or the second wire. When temperature of the thermal circuit breaker is excessive, the thermal circuit breaker is disconnected, current continues to supply power to low-current electrical appliances through the protective resistor.
