Mechanical electric baking appliance and heating control method of same

Abstract

The invention discloses a mechanical electric baking appliance and a heating control method of the same, belongs to the field of kitchen electric appliances and solves the problems of existing electric baking appliances that temperature control effects are poor and the temperature variation amplitude is large. A heating control circuit of the electric baking appliance disclosed by the invention comprises a first heating branch which comprises a heater H1, a temperature controller K1, a second heating branch with a heater H2 and a temperature controller K2, wherein the temperature controller K1 and the temperature controller K2 are normally closed temperature controllers; a break-off temperature T1 of the temperature controller K1 is smaller than a break-off temperature T2 of the temperature controller K2; at a temperature rise stage, the heater H1 and the heater H2 start heating and temperature rise at the same time, and the first heating branch is broken off and a constant-temperature stage will be started when the actual temperature T0 increases to the break-off temperature T1; and at the constant-temperature stage, the second heating branch will be broken off and the heater H2 stops heating when the actual temperature T0 increases to the break-off temperature T2, and the second heating branch will be connected and the heater H2 starts heating when the actual temperature T0 decreases to a reset temperature S2 of the temperature controller K2.

Description

Technical field [0001] The invention relates to the field of kitchen appliances, in particular to a mechanical electric grilling appliance and a heating control method thereof. Background technique [0002] Electric grilling appliances are mainly air fryer, electric oven, electric frying pan, electric baking pan and other electrical products used for baking. Most of these electrical products rely on electric heaters to generate heat energy, and heat energy is used to bake food through conduction, radiation, etc. Roasting heating is achieved by controlling the on and off of the electric heater to control the baking temperature. A single heating method and temperature control method cause the electric grill to rise to a relatively high temperature in the early stage of cooking. The body, surface coating and other electrical components will cause damage and reduce the service life. After that, the electric grill keeps heating at full power until the food is cooked. This not only was...

Problems solved by technology

[0002] Electric baking appliances are mainly air fryers, electric ovens, electric frying pans, electric baking pans and other electrical products used for baking. Most of these electrical products rely on electric heaters to generate heat energy, and the heat energy bakes food through conduction and radiation. Baking heating, the control of the baking temperature is achieved by controlling the on-off of the electric heater. The single heating method and temperature control method cause the electric grill to rise to a relatively high temperature in the early stage of cooking. The body, surface coating and other electrical components will cause damage and reduce the service life. Then the electric grill keeps heating at full power until the food is cooked. Difference
