Electric cooking device as well as power failure recovery device and power failure recovery control method thereof

Abstract

The invention discloses a power failure recovery device of an electric cooking device. The power failure recovery device comprises a zero crossing detection circuit, a power failure time delay circuit and a control circuit, wherein the zero crossing detection circuit detects zero crossing signals of alternating current commercial power input into the electric cooking device; the power failure time delay circuit detects the power failure time of the electric cooking device; the control circuit is respectively connected with the zero crossing detection circuit and the power failure time delay circuit, and the control circuit judges whether the electric cooking device generates power failure or not according to the zero crossing signals, and judges whether the electric cooking device is controlled to recover the work state during the power failure according to the power failure time of the electric cooking device during the re-electrification after the power failure of the electric cooking device. The power failure recovery device has the advantages that the power failure time of the electric cooking device during the re-electrification can be judged, and whether the electric cooking device is controlled to recover the work state during the power failure or not is judged according to the power failure time, so the requirements of users are sufficiently met, and the experience of the users is improved. The invention also discloses the electric cooking device and a power failure recovery method of the electric cooking device.

Description

technical field [0001] The invention relates to the technical field of living appliances, in particular to a power-off recovery device for an electric cooker, an electric cooker with the power-off recovery device, and a power-off recovery control method for the electric cooker. Background technique [0002] With the rapid development of electronic technology, the functions of electronic microwave ovens are becoming more and more abundant. Today's microwave ovens can not only set cooking time and firepower, but also set clocks, demonstration modes and more personalized modes. [0003] However, in the existing electronic microwave oven, when the power supply is powered off and powered on again, when the computer board is powered on, it is reset to the initial state. For example, when the user sets the clock, if there is a sudden power failure for a few seconds, the computer board will be reset to the initial state after power-on, and the clock is also the initial time, so the ...

AI Technical Summary

Problems solved by technology

However, if the user powers on the microwave oven every other day, if the microwave oven returns to the working state when the power was off, the clock is obviously wrong, and the working mode may not be what the user wants, which will also bring inconvenience to the user.
