Description
Technical Field
[0001] The utility model relates to the technical field of kitchen auxiliary appliances, in particular to an intelligent device for assisting cookers. Background Art
[0002] With the continuous progress of the times, kitchen utensils are constantly updated and changed with the development of science and technology. More and more smart products are used to assist kitchen operations. Some of these products use ToF sensors to detect distance, infrared sensors to detect temperature, or optical cameras for machine learning to determine boiling and overflow situations and issue alarms.
[0003] When the early warning function is realized through optical sensors, the cost is relatively high and the development and use are also difficult. Moreover, when the temperature change is detected by infrared sensors or the distance change of the water surface is detected by ToF sensors, only overflow detection and warning can be performed after boiling. It is impossible to warn the user before boiling. Therefore, further improvement can be made. Utility Model Content
[0004] To solve the above-mentioned problems, the utility model provides the following technical solutions: a cooking auxiliary intelligent device, comprising a range hood, wherein exhaust motors are arranged on both sides inside the range hood, and an exhaust pipe is connected to one end of the exhaust port of the exhaust motor, a bottom plate is arranged on the bottom side of the range hood, time-of-flight sensors are arranged on the left and right halves of the bottom side of the bottom plate, a controller is arranged on the bottom side of the bottom plate, and the time-of-flight sensor and the controller are signal-connected, mesh plates are embedded on both sides of the bottom surface of the bottom plate, exhaust ports are arranged near the middle of the mesh plates on both sides, and the exhaust ports are connected to the end of the exhaust pipe, and a buzzer is arranged on the bottom side of the bottom plate.
[0005] As an optimization, a number of time-of-flight sensors are distributed in an array, and the pixels of each time-of-flight sensor are 8×8, and each time-of-flight sensor has a FOV angle of 55°×61°, so that the downward coverage angle of the time-of-flight sensor can surround the entire stove surface, thereby being able to determine whether there are cookers on the stove.
[0006] As an optimization, the buzzer and controller signal are connected. The steam generated by the boiling water in the cooker will block the reflected ray pixels of the time-of-flight sensor. Since the steam blocks the radiation pixels of many related pixels, the signal ratio, that is, the signal strength, will produce output distortion, and then present a certain graph. Therefore, the system can judge that the water or similar liquid is about to boil, and then control the buzzer to make a buzzing sound to warn.
[0007] As an optimization, the exhaust motor and controller signal are connected. Since changes in the amount of steam, moisture and smoke will cause differences in the response of the time-of-flight sensor, the exhaust motor can be turned on and the speed can be adjusted from low to high via the controller based on this difference. When the amount of steam or smoke drops below a lower threshold, the exhaust motor will be controlled to be turned off.
[0008] As an optimization, a lighting assembly is provided on the bottom side of the base plate, and the lighting assembly includes a mounting frame embedded in the bottom side of the base plate, an LED light strip is bonded to the inner wall of the mounting frame, and a glass cover is embedded at the opening edge of the mounting frame.
[0009] As an optimization, the LED light strip is connected to the controller signal, and the flight time sensor can detect the presence of cookware, and can also detect the user's moving hands, so that the system can determine whether the user is using the cookware to cook, and then control the LED light strip to turn on for auxiliary lighting, which can help the user see the cookware more clearly for cooking. Once there are no more cookware on the stove surface or there is no user activity for a long time, the system will turn off the LED light strip to avoid unnecessary waste.
[0010] As an optimization, the glass cover is made of flat glass, which has the characteristics of high transparency, excellent surface finish, and excellent physical and optical properties, which makes it easy to illuminate with LED light strips and also facilitates cleaning of oil stains attached to the surface of the glass cover after long-term use.
[0011] The beneficial effects of the utility model are:
[0012] 1. The cooker auxiliary intelligent device can fully cover the stove through the time-of-flight sensor, and can accurately monitor the stove. When the user places the cooker on the stove, the signal ratio brought by the cooker surface will change significantly and will be received by the controller. The controller will determine the position of the cooker, thereby achieving the purpose of monitoring whether the cooker exists.
[0013] 2. The cooker auxiliary intelligent device, when the temperature of water or similar liquids reaches a high temperature, will produce steam or moisture. When the amount of steam or moisture is sufficient, the steam or moisture will block the light path of the relevant pixels, which will cause a significant distortion of the signal ratio and have certain graphic characteristics. This phenomenon will tell the controller that the water or similar liquids are about to boil, and then the controller will control the buzzer to activate the buzzer to remind the user, thereby achieving the purpose of warning the user before boiling and reducing costs.
[0014] 3. The cooker auxiliary intelligent device determines the amount of steam / moisture / smoke through signal comparison during the period of increasing steam / moisture / smoke. Once the amount of steam / moisture / smoke exceeds a certain threshold or meets a certain pattern, it will notify the controller to automatically turn on the exhaust motor and automatically adjust the speed according to the change in the amount of steam / moisture / smoke. Conversely, if the amount of steam / moisture / smoke drops below the lower threshold, the exhaust motor will be automatically turned off, thereby achieving the effect of only adjustment.
[0015] 4. When the smart device detects the presence of cooking utensils and the user's hands are cooking, it will turn on the LED light strip for lighting through the controller, thereby assisting the user in cooking. When there are no cooking utensils on the stove or there has been no user activity for a long time, the controller will automatically turn off the LED light strip to avoid unnecessary waste.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-2A cooking utensil auxiliary intelligent device comprises a range hood 1, exhaust motors 2 of model YCY180B-4 are arranged on both sides of the range hood 1, and an exhaust pipe is connected to one end of the exhaust port of the exhaust motor 2, a bottom plate 3 is arranged on the bottom side of the range hood 1, and time-of-flight sensors 4 are arranged on the left and right halves of the bottom side of the bottom plate 3, a plurality of time-of-flight sensors 4 are distributed in an array, and each time-of-flight sensor 4 has 8×8 pixels, and each time-of-flight sensor 4 has a FOV angle of 55°×61°, so that the downward coverage angle of the time-of-flight sensor 4 can surround the entire stove surface, and thus it can be determined whether there is a cooker on the stove;
[0022] See also Figure 1-2 A controller 5 is provided on the bottom side of the bottom plate 3, and the flight time sensor 4 is connected to the controller 5 by signal, and the exhaust motor 2 is connected to the controller 5 by signal. Since the change of the amount of steam, moisture and smoke will cause the response of the flight time sensor 4 to be different, the exhaust motor 2 can be turned on and the speed can be adjusted from low to high according to the difference through the controller 5, and when the amount of steam or smoke drops below the lower threshold, the exhaust motor 2 will be controlled to be turned off;
[0023] See also Figure 1-2 , mesh plates 6 are embedded on both sides of the bottom surface of the bottom plate 3, and exhaust ports 7 are arranged near the middle of the mesh plates 6 on both sides, and the exhaust ports 7 are connected to the end of the exhaust pipe. A buzzer 8 is arranged on the bottom side of the bottom plate 3, and the buzzer 8 is connected to the controller 5 by signal. The water vapor generated by the boiling of water in the cooker will block the reflected ray pixels of the time-of-flight sensor 4. Since the steam blocks the radiation pixels of the relevant pixels, the signal ratio, that is, the signal intensity, will produce output distortion, and then a certain pattern will be presented, so that the system can judge that the water or similar liquid is about to boil, and then the buzzer 8 will be controlled to make a buzzing sound for warning.
[0024] See also Figure 2-3 , a lighting assembly 9 is provided on the bottom side of the bottom plate 3, and the lighting assembly 9 includes a mounting frame 10 embedded in the bottom side of the bottom plate 3, and an LED light strip 11 is bonded to the inner wall of the mounting frame 10, and the LED light strip 11 is connected to the controller 5 by signal, and can detect the existence of the cooking utensils through the time-of-flight sensor 4, and can also detect the user's moving hands, so that the system can determine whether the user is using the cooking utensils to cook, and thus control the LED light strip 11 to turn on for auxiliary lighting, which can help the user see the cooking utensils more clearly for cooking. And once there are no more cooking utensils on the stove surface or no user activities for a long time, the system will turn off the LED light strip 11 to avoid unnecessary waste;
[0025] See also Figure 2-3A glass cover 12 is embedded in the opening edge of the mounting frame 10. The glass cover 12 is made of flat glass. Flat glass has the characteristics of high transparency, excellent surface finish, and excellent physical and optical properties, which makes it easy for the LED light strip 11 to illuminate, and it is also convenient to clean the oil stains attached to the surface of the glass cover 12 after long-term use.
[0026] When using, refer to Figure 1-3 The flight time sensor 4 can monitor the entire surface of the target and output the reflection intensity of the target object to the infrared ray, that is, the signal ratio. When there is no cooker on the stove, the signal ratio of all pixels is about A. When the user places the cooker on the stove, the signal ratio of some pixels that can emit radiation in the relevant area is B. The difference between A and B is obvious, and the system can judge whether there is a cooker on the stove based on this.
[0027] After analyzing whether the cooker exists, the system continuously monitors the signal ratio of the cooker that can reflect the radiation. When water or similar liquid reaches a high temperature of 85°C, the water begins to generate steam / water. When the boiling state becomes strong enough, the amount of steam / water is large enough to block these pixels. Since the steam blocks the radiation path of the relevant pixels, it is equivalent to noise causing the signal ratio to produce output distortion, and this distortion will present a certain pattern. Therefore, the system will determine that the water or similar liquid is about to boil, and then control the buzzer 8 to emit a buzzer sound through the controller 5 to warn the user;
[0028] At the same time, as the amount of steam / moisture / smoke changes from low to high, the response of the flight time sensor 4 will also be significantly different, so the controller 5 can start the exhaust motor 2 at the lower limit and adjust the speed from low to high according to different detection amounts, and once the amount of steam / smoke drops below the lower threshold, the controller 5 will control the exhaust motor 2 to be turned off;
[0029] Since the time-of-flight sensor 4 has the ability to detect the presence of cooking utensils and can detect the user's moving hands, through these two inputs, the system can know whether the user is in front of the stove and is using the current cooking utensils to cook. Therefore, the system will control the controller 5 to turn on the LED light strip 11 for auxiliary lighting to help the user see the cooking utensils more clearly. Once there are no more cooking utensils placed on the stove surface or there is no user activity for a long time, the system will turn on the LED light strip 11 to avoid waste.
[0030] In summary, the cooker auxiliary intelligent device can fully cover the stove through the time-of-flight sensor 4, and thus can accurately monitor the stove. When the user places the cooker on the stove, the signal ratio brought by the cooker surface will change significantly and will be received by the controller 5. The controller 5 will determine the position of the cooker, thereby achieving the purpose of monitoring whether the cooker exists.
[0031] When the temperature of water or similar liquids reaches a high temperature, steam or moisture will be generated. When the amount of steam or moisture is sufficient, the steam or moisture will block the light path of the relevant pixels, which will cause the signal ratio to be significantly distorted with certain graphic characteristics. This phenomenon will tell the controller 5 that the water or similar liquid is about to boil, and then the controller 5 will control the buzzer 8 to activate the buzzer sound to remind the user, thereby achieving the purpose of warning the user before boiling and reducing costs.
[0032] During the period of increasing steam / moisture / smoke volume, the steam / moisture / smoke volume is judged by signal comparison. Once the steam / moisture / smoke volume exceeds a certain threshold or meets a certain pattern, the controller 5 will be notified to automatically turn on the exhaust motor 2, and the speed will be automatically adjusted according to the change in the steam / moisture / smoke volume. Conversely, if the steam / moisture / smoke volume drops below the lower threshold, the exhaust motor 2 will be automatically shut down, thereby achieving the effect of only adjustment.
[0033] When the presence of cooking utensils is detected and the user's hands are cooking, the controller 5 will turn on the LED light strip 11 for lighting, which will assist the user in cooking. When there are no cooking utensils on the stove or there is no user activity for a long time, the controller 5 will automatically turn off the LED light strip 11 to avoid unnecessary waste.
[0034] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
