Toaster control method

Abstract

The invention discloses a toaster control method which has the characteristics of energy conservation, low complete machine temperature and low cost and can prevent a toaster from occurring fire accidents. The method of the invention comprises the following steps: 1. a temperature sensor detects the temperature in a heating groove of the toaster and outputs temperature data; 2. the received temperature data is processed by a microprocessor; 3. whether the temperature data is within the set temperature range is judged, if the temperature exceeds the high-temperature limit value in the temperature range, the power supply of the heating element in the heating groove is switched off; if the temperature lowers the low-temperature limit value in the temperature range, the power of the heating element is switched on; 4. the heating power source of the heating element is switched off by a control circuit when the set toast time is reached. The invention also discloses another control method of intermittence energization of the heating element in the heating groove of the toaster.

Description

technical field [0001] The invention relates to a control method of a toaster oven, in particular to a control method for intermittently energizing a heating element in a heating groove of the toaster oven. Background technique [0002] At present, toaster ovens are small household appliances commonly used in families and units. In the prior art, the steps for using the toaster oven are: 1. The user sets the corresponding baking time gear; 2. Put the bread into the heating tank of the toaster oven; 3. Press the carriage to connect to the heating tank The power supply of the heating element, the heating element is continuously energized at a rated power to heat the bread; 4. After the baking time of the bread reaches the baking time set by the program, the bread is lifted by the bracket set on the carriage, and the heating element is cut off at the same time power supply. [0003] In the prior art, there are also covered bread ovens, such as the Chinese invention patent fil...

AI Technical Summary

Problems solved by technology

[0004] A safe, reliable, hygienic and energy-saving toaster with a cover is disclosed in the above-mentioned patent, but this toaster with a cover has the following disadvantages at the same time: 1. No matter how high the temperature in the bread heating tank is, the toaster with a cover will , the bread is heated at a constant power until the baking time set by the program is reached, so the temperature of the whole machine is high during the heating process

2. When a small bread is put into the toaster oven, since the heating power of the heating element remains unchanged, the temperature of the whole machine of the toaster oven is increased even more, a large amount of heat energy is lost, and there is a risk of the bread catching fire at the same time. Security risks

3. In the safety inspection, because the toaster oven with a cover is prone to the defect of overheating of the whole machine, it is necessary to enlarge the shape of the toaster oven in the design, so as to solve the problem of its own overheating, so that Will increase the design cost, manufacturing cost and transportation cost of the product
