[0003] Existing water level detection usually relies on a mechanical float switch to detect whether there is water in the water tank. The mechanical float switch detection method has problems of detection delay and insufficient accuracy. It cannot detect the specific amount of water in the water tank, resulting in the user being unable to know the remaining water amount in the water tank in time. When the user needs to cook a dish, if there is a lack of water in the middle of cooking, firstly, the user may not be next to the machine and cannot be informed of the water shortage status in time, resulting in interruption of the cooking process; secondly, when there is a lack of water, the working process is suspended, resulting in insufficient steam in the steamer, affecting the cooking effect.

[0063] Embodiment 1

[0064] This embodiment provides a water level detection device, such as Figure 1 As shown, it includes a water tank 100, a bracket 200 and a detection plate 300. The bracket 200 is used to support the water tank 100. The water tank 100 and / or the bracket 200 are provided with an assembly groove 210. The detection plate 300 is inserted into the assembly groove 210. The detection plate 300 is provided with at least two mutually parallel capacitor plates. The two capacitor plates are both attached to the outer wall of the water tank 100. In each measuring time period, the change of the water height in the water tank 100 will cause the change of the capacitance value between the two mutually parallel capacitor plates. The capacitance detection circuit converts the value change into voltage change information to perform water level detection to obtain water level data, thereby realizing non-contact dynamic real-time monitoring of water level, greatly reducing detection delay, and improving water level detection accuracy.

[0065] like Figure 2 As shown, in this embodiment, an assembly groove 210 is provided on the bracket 200, and the detection plate 300 is inserted into the assembly groove 210 on the bracket 200. The position of the detection plate 300 is fixed by the bracket 200 so that its relative position with the water tank 100 remains stable, which simplifies the installation process of the detection plate 300 and improves the convenience of installation of the detection plate 300.

[0066] like Figure 3As shown, in another embodiment, an assembly groove 210 is provided on the outer wall of the water tank 100, and the detection plate 300 is inserted into the assembly groove 210 of the outer wall of the water tank 100, which further optimizes the spatial layout of the cooking equipment and makes the whole machine more compact; and the detection plate 300 is directly attached to the outer wall of the water tank 100, which can more accurately sense the change of water volume in the water tank 100, thereby improving the accuracy and sensitivity of water level detection.

[0067] In another embodiment, assembly grooves 210 are provided on the outer wall of the water tank 100 and the bracket 200. When the water tank 100 is installed on the bracket 200, a limiting space is formed together. The detection board 300 is inserted in the limiting space, and the two capacitor plates on the detection board 300 are both in contact with the outer wall of the water tank 100, so that the detection board 300 can be hidden installed, and the overall design is more simple and beautiful.

In this embodiment, the protective shell 310 can be designed to be a material such as high temperature resistant, waterproof, and oil-proof according to the use environment of the cooking device. Specifically, the protective shell 310 can be made of silicone, polytetrafluoroethylene, polypropylene, etc., so as to enhance the environmental adaptability of the water level detection device.

[0069] Embodiment 2

[0070] This embodiment provides a water level detection device, which is basically the same as the first embodiment, and differs from the first embodiment in that: Figure 4-Figure 5 As shown, the water level detection device also includes an elastic pressure component 400, which is arranged on the side of the detection plate 300 away from the water tank 100. The elastic pressure component 400 is used to apply pressure to the detection plate 300 so that it always fits tightly against the outer wall of the water tank 100, avoiding detection errors caused by poor contact, thereby greatly improving the accuracy and sensitivity of water level detection.

[0071] Optionally, the elastic pressure assembly 400 includes a positioning plate 410, an elastic member 420 and a pressure rod 430. The positioning plate 410 is arranged on the bracket 200. One end of the elastic member 420 is connected to the positioning plate 410, and the other end is connected to the pressure rod 430. The elastic member 420 is used to drive the pressure rod 430 to press against the side of the detection plate 300 away from the water tank 100 to prevent the detection plate 300 from loosening or shifting, reduce the air gap between the detection plate 300 and the water tank 100, and improve the detection accuracy and the reliability of the detection results.

[0072] Optionally, the elastic member 420 in this embodiment is a spring with good elasticity, which can provide sufficient elastic force for the pressing rod 430 to ensure that the pressing rod 430 stably presses the detection plate 300 against the outer wall of the water tank 100. It should be noted that the elastic member 420 can select springs or other elastic elements with different stiffness according to actual needs to adjust the pressure of the pressing rod 430, adapt to water tanks 100 and detection plates 300 of different materials, thicknesses and shapes, and enhance the versatility and flexibility of the device.

[0073] Optionally, the elastic pressing assembly 400 in this embodiment may include 3-6 springs, each spring is connected to a pressing rod 430, and each pressing rod 430 can abut against the side of the detection plate 300 away from the water tank 100. In this embodiment, it is preferred that 3 springs are arranged on the positioning plate 410, and each spring is connected to a pressing rod 430 to press and fix the detection plate 300.

[0074] Optionally, a guide arm 220 is provided on the bracket 200, and the pressure rod 430 is slidably connected to the guide arm 220. The guide arm 220 can provide a guide for the movement of the pressure rod 430, ensuring that the pressure rod 430 applies force in a direction perpendicular to the detection plate 300, thereby improving the stability of the detection plate 300.

[0075] Embodiment 3

[0076] This embodiment provides a water level detection device, which is basically the same as the first embodiment. The difference from the first embodiment is that the water level detection device also includes a pin interface component 510, and the pin interface component 510 is used to supply power and transmit information to the detection board 300, thereby avoiding the complexity of additional wiring, improving the overall integration of the device, and making the cooking device more compact.

[0077] Optionally, the pin interface component 510 is provided with a socket on the detection board 300, and the socket has a built-in pin, which is convenient for connecting with an external power plug. The pin interface component 510 is connected to the detection board 300 through the pin, providing power supply and data transmission functions for the detection board 300. This design has the advantages of reliable connection and convenient installation, and at the same time occupies less space, which is suitable for the use requirements of compact equipment.

[0078] Embodiment 4

[0079] This embodiment provides a water level detection device, which is basically the same as the first embodiment. The difference from the first embodiment is that the water level detection device also includes a POGO Pin component 520. The POGO Pin component 520 is used to supply power and transmit information to the detection board 300, which can reduce complex wiring requirements, simplify the structure of the water level detection device, and improve the integration of the water level detection device.

[0080] Compared with the traditional contact connection method, the POGO Pin assembly 520 contacts the detection board 300 through elastic pins. The POGO Pin assembly 520 has better contact stability and can effectively avoid poor contact problems caused by vibration or long-term use. The waterproof level of the POGO Pin assembly 520 can also be adjusted as needed according to assembly requirements.

[0081] Embodiment 5

[0082] like Figure 6 As shown, this embodiment provides a water level detection method for a cooking device, which is applied to the water level detection device in any of the above embodiments. The water level detection method for a cooking device includes:

[0083] S1, obtaining the amount of water L1 required for cooking, and the water level detection device detects the water level information L2 of the water tank 100;

[0084] S2, determine whether L2 is greater than or equal to (L1 + preset remaining water volume Ls), if L2 ≥ (L1 + Ls), start cooking; if L2 < (L1 + Ls), prompt the user to add water, and start cooking after y prompts;

[0085] S3. During the cooking process, the water level information L2 of the water tank 100 is compared with the water shortage reminder threshold Lq. If L2 ≥ Lq, cooking continues until the end; if L2 < Lq, the user is prompted to add water, and cooking is stopped after y prompts.

[0086] In this embodiment, the number of times of water replenishment y times can be 2 times-10 times, specifically 2 times, 3 times, 4 times, 5 times, 6 times, 7 times, 8 times, 9 times, 10 times, etc. In this embodiment, 3 times is preferably prompted.

[0087] The water level detection method for cooking equipment provided in the present embodiment detects the water level information L2 of the water tank 100 through the water level detection device before cooking begins, and compares it with the sum of the water volume L1 required for this cooking and the preset remaining water volume Ls, to ensure that there is enough water in the water tank 100, to avoid the pumping system from sucking in air and generating bubbles due to too low water level during cooking, thereby maintaining the stability of the cooking process and the safety of the cooking equipment, and improving the cooking effect and cooking efficiency; during the cooking process, the water level information L2 is continuously monitored and compared with the water shortage reminder threshold Lq, so that the low water level can be discovered in time, to avoid excessive operation of the equipment or unnecessary energy waste due to too low water level during cooking, thereby improving the energy saving effect and service life of the cooking equipment.

[0088] Optionally, if L2<(L1+Ls), step S2 further includes:

[0089] S21, calculating the amount of water Lb1 that needs to be replenished, and prompting the user to replenish at least Lb1 of water;

[0090] S22. The water level detection device detects the water level of the water tank 100 to determine whether there is water replenishment action. If there is water replenishment action, return to S1; if there is no water replenishment action, the reminder number +1, the reminder number is less than y times, then return to step S21, the reminder number is greater than or equal to y times, and start cooking.

[0091] Step S21 enables the user to clearly know the amount of water required to be replenished, thereby avoiding the situation where the water level during cooking is too low due to untimely or insufficient water replenishment, thereby affecting the cooking effect.

[0092] Step S22 detects the water replenishment action in real time. Once it is detected that the user has replenished enough water, the system will automatically return to step S1 to continue detecting and cooking. This optimizes the user's operating experience, reduces the repetitiveness of operations, and makes the use of cooking equipment smoother and more efficient.

[0093] Optionally, if L2<Lq, step S3 further includes:

[0094] S31, prompting the user to replenish at least Lb2 of water;

[0095] S32, the water level detection device detects the water level of the water tank 100 to determine whether there is water replenishment action. If there is water replenishment action, return to S3; if there is no water replenishment action, the reminder number +1, the reminder number is less than y times, then return to step S31, the reminder number is greater than or equal to y times, and the cooking is ended.

[0096] Step S31 enables the user to clearly know the amount of water required to be replenished, thereby avoiding the situation where the water level is too low during cooking due to untimely or insufficient water replenishment, thereby affecting the cooking effect.

[0097] Step S32 detects the water replenishment action in real time. Once it detects that the user has replenished enough water, the system will automatically return to step S3 to continue detection and cooking, which optimizes the user's operating experience, reduces the repetitiveness of operations, and makes the use of cooking equipment smoother and more efficient. If the number of reminders exceeds the set value and the user does not replenish water, the system will automatically end cooking to prevent the equipment from drying out, overheating, and other problems caused by lack of water, thereby protecting the equipment from damage.

[0098] Specifically, if Figure 6 As shown, the detailed detection process of the water level detection method provided in this embodiment is as follows:

[0099] S1, obtaining the amount of water L1 required for cooking, and the water level detection device detects the water level information L2 of the water tank 100;

[0100] S2, determine whether L2 is greater than or equal to (L1+preset remaining water volume Ls), if L2≥(L1+Ls), start cooking;

[0101] If L2<(L1+Ls), then proceed to steps S21 and S22;

[0102] S21, calculating the amount of water Lb1 that needs to be replenished, and prompting the user to replenish at least Lb1 of water;

[0103] S22. The water level detection device detects the water level of the water tank 100 to determine whether there is water replenishment action. If there is water replenishment action, return to S1; if there is no water replenishment action, the reminder number +1, the reminder number is less than y times, then return to step S21, the reminder number is greater than or equal to y times, and start cooking.

[0104] S3, during the cooking process, compare the water level information L2 of the water tank 100 with the water shortage reminder threshold Lq, and if L2≥Lq, continue cooking until the end;

[0105] If L2<Lq, proceed to steps S31 and S32;

[0106] S31, prompting the user to replenish at least Lb2 of water;

[0107] S32, the water level detection device detects the water level of the water tank 100 to determine whether there is water replenishment action. If there is water replenishment action, return to S3; if there is no water replenishment action, the reminder number +1, the reminder number is less than y times, then return to step S31, the reminder number is greater than or equal to y times, and the cooking is ended.

[0108] The cooking equipment water level detection method provided in this example sets up water level detection and water replenishment prompting functions before and during cooking, avoiding cooking failure or equipment damage due to insufficient water, and ensuring cooking effects and equipment safety.

[0109] Embodiment 6

[0110] like Figure 7 As shown, this embodiment provides a water injection amount control method, which is applied to step S2 and / or step S3 in embodiment 5. The water injection amount control method includes:

[0111] Sz1, obtaining the current inner pot temperature T1, the number of humidification times required for cooking N1, and the water level detection device detecting the current water level height L3 of the water tank 100;

[0112] Sz2. Obtain the model J1 of the cooking device and the preset humidity of the inner pot, calculate the water height to be filled, if there is no residual water in the water pipe under the model J1, then fill the water height △L1; if there is residual water in the water pipe under the model J1, calculate the water height △L2;

[0113] Sz3. The water level detection device detects that the water level height of the water tank 100 is (L3+△L1) or (L3+△L2), and the water filling is completed.

[0114] By combining the current inner pot temperature T1, the number of humidification times N1 required for cooking and the water level height L3 of the water tank 100, the required water injection amount can be accurately calculated to ensure that the humidity of the inner pot is always in the optimal range, avoiding the taste and quality of the food affected by too much or too little water injection, thereby improving the cooking effect of the ingredients.

[0115] In addition, the water injection volume control method dynamically adjusts the water injection strategy according to the model J1 of the cooking equipment. For example, the water injection volume height △L1 or △L2 is adjusted by detecting whether there is residual water in the water pipe, thereby effectively avoiding unnecessary waste of water resources caused by excessive water injection. This function takes into account both energy saving and environmental protection, and reduces the water cost of the equipment.

[0116] Optionally, when the cooking device is a normal pressure cooking device, the water injection amount can be corrected through the wireless cloud platform. For example, after the wireless networking module in the normal pressure cooking device is connected to the network, the system locates the area where the cooking device is located through the network and obtains the altitude and air pressure information of the area where the cooking device is located; during the calculation of △L1 or △L2, the built-in algorithm corrects the calculation result through the local altitude air pressure information to adapt to the difference in steam volume generated when the air pressure is different. This solves the problem of steam volume differences under different altitudes and air pressure environments, ensures that the water injection amount matches the environment in which the cooking device is running, thereby optimizing the steam generation efficiency and improving the cooking effect.

[0117] Optionally, when the cooking device is a micro-pressure cooking device, an air pressure sensor is built into the cavity of the cooking device. During the calculation of △L1 or △L2, the built-in algorithm corrects the water injection amount based on the air pressure information, thereby solving the problem of difference in steam volume under different altitudes and air pressure environments, ensuring that the water injection amount matches the operating environment of the cooking device, thereby optimizing the steam generation efficiency and improving the cooking effect.

[0118] It should be noted that the wireless networking module in the cooking device and the built-in algorithm program in the cooking device are technical means well known to those skilled in the art and will not be elaborated here.

[0120] like Figure 8 As shown, this embodiment provides a water tank water replacement reminder method, which is basically the same as the fifth embodiment, and the difference from the fifth embodiment is that step S3 also includes a water tank water replacement reminder method after the cooking is completed, and the water tank water replacement reminder method includes:

[0121] Sh1. Obtain the running status of the cooking device. After cooking is finished and the cooking device is turned off, the timer starts timing T;

[0122] Sh2. When the cooking device is turned on, if T>t, the user is reminded to change the water source, and the reminder program ends after x times; when the cooking device is turned on, if T≤t, the cooking device is turned on, and the timer is reset to zero. In this embodiment, t can be set to 72h, and in other embodiments, t can be set to 24h, 48h, etc., and there is no specific limitation on the value of t.

[0123] If T>t when the device is turned on, the user is reminded to change the water source, and the program ends after x reminders; if T≤t when the device is turned on, the device starts normally and the timer is reset to zero. Water stored for a long time may cause water quality to deteriorate or even breed bacteria. Through the water change reminder, users can change the water source in time to ensure the hygiene and safety of the cooking process.

[0124] Optionally, step Sh2 further includes:

[0125] Sh21, check whether there is an action of plugging or unplugging the water tank 100. If there is an action of plugging or unplugging the water tank 100, stop reminding. If there is no action of plugging or unplugging the water tank 100, the program ends after reminding x times.

[0126] If the user fails to change the water source in time, the system will remind the user multiple times (at most x times) to ensure that the user notices the water quality problem, but will not interfere with normal use in an infinite loop. In this embodiment, the number of reminders for water replenishment x times can be 2 times to 10 times, specifically 2 times, 3 times, 4 times, 5 times, 6 times, 7 times, 8 times, 9 times, 10 times, etc. In this embodiment, it is preferred to remind 3 times.

[0127] Optionally, a gravity sensor can be set on the bracket 200 to sense the change in the weight of the water tank 100, or a photoelectric sensor can be set on the bracket 200 to detect obstruction or displacement during the plugging and unplugging process. The user's plugging and unplugging actions of the water tank 100 can be accurately identified. The specific detection circuit is a technical means well known to technicians in this field and will not be elaborated here.
