Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] Microwave Example

[0026] Such as figure 1 As shown, the microwave oven includes a microwave oven body, and the power supply supplies power to the microwave oven body; the microwave oven also includes a no-load automatic power-off control device, and the no-load automatic power-off control device includes a control switch, a control device, an optical signal receiving module and an optical signal receiving module. The receiving module is equipped with an optical signal transmitting module, and the control switch is set on the power supply circuit of the microwave oven body. The control device is connected to the optical signal receiving module for sampling, and is connected to the control switch. Moreover, the optical signal transmitting module and the optical signal receiving module are arranged in the heating cavity of the microwave oven, and the t...

Abstract

The invention relates to a no-load automatic power off control apparatus for a microwave oven, and the microwave oven. The no-load automatic power off control apparatus comprises a control switch, a control apparatus, an optical signal receiving module and an optical signal transmitting module, wherein the control switch is serially arranged on a power supply loop of the microwave oven; the control apparatus is in sampling connection with the optical signal receiving module to control and connect the control switch; and the optical signal transmitting module and the optical signal receiving module are arranged in a heating cavity of the microwave oven. When there is no food in the microwave oven, the optical signal receiving module can receive a signal from the optical signal transmitting module, at the moment, the control switch in the power supply loop of the microwave oven is controlled to be switched off to realize the automatic power off of the microwave oven in a no-load state in order to enable the microwave oven not to work, so that electric energy can be reduced, and noise is not generated; and in addition, a magnetron, or a high-voltage fuse and the like of the microwave oven are not damaged, so that damage to the microwave oven is avoided.

Description

technical field [0001] The invention relates to a microwave oven no-load automatic power-off control device and a microwave oven, belonging to the field of safe operation of the microwave oven. Background technique [0002] With the increasing pace of work, microwave ovens are more and more valued by people because of their fast heating speed and easy to use advantages, especially the people who go to work, and more and more people use microwave ovens. However, in some cases, For example: working people have a hard day, come back from get off work, in a hurry to heat up meals, in a hurry, forget to put the food in the microwave oven and press the start button, after a few minutes, the set time is up, open the oven door, but It was found to be empty; or, the child turned the switch and timer knob of the microwave oven, and the microwave oven worked. In the above two cases, the microwave oven works under no-load conditions. In this situation, there are two main disadvantages....
