Intruded object detection device for cooking utensil, and intrusion detection and low power consumption detection methods thereof

Abstract

The present invention discloses an intruded object detection device for a cooking utensil, and intrusion detection and low power consumption detection methods thereof. The intruded object detection device for the cooking utensil comprises at least two optical detection devices arranged at an opening of the cooking utensil, and an included angle of two straight lines where the light directions of the two optical detection devices arranged at the opening are located is 90 DEG. The low power consumption detection method of the intruded object detection device comprises that: a main controller detects whether there is an external power supply; when detecting that the external power supply is not provided, that the power is supplied by using a rechargeable battery is determined, and the main controller performs voltage detection on the rechargeable battery; and when the voltage of the rechargeable battery is not lower than the preset minimum threshold, low power consumption detection is used. According to the technical scheme of the present invention, based on retaining the traditional rice cooker heat dissipation and other structures, the intruded object entering the cooking utensil can be driven out, and if the intruded object cannot be driven out, an alarm device is activated to remind the user; the user can observe the location of the intruded object by using a display module such as liquid crystal and the like; and when the cooking utensil is not used by the user, the optical detection devices can be activated with low power consumption.

Description

technical field [0001] The invention relates to optical detection and energy-saving technologies, in particular to an intrusion detection device for a cooking utensil, an intrusion detection and a low-power consumption detection method. Background technique [0002] The patent document with the notification number CN206443578U and titled "Cooking Appliance" discloses a sealed structure of an electric rice cooker. Because the heating device is located in the casing, and the casing adopts a fully sealed device, only the medium and the heat dissipation panel are used to dissipate heat, which is different from the traditional Compared with the rice cooker, the heat dissipation effect is not good, and it is easy to cause food deterioration. Moreover, there is a hole in the structure, and there is still the possibility of reptiles entering. Once reptiles enter, it is easy to affect the user experience. [0003] The patent document with the announcement number CN206525919U and titl...
