[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a kitchen oil and salt control device. Background Technology
[0002] Currently, there are various devices and methods on the market for controlling oil and salt usage in the kitchen. Some products use simple measuring containers, with graduations to roughly control the amount of oil and salt used; others are smart kitchen devices that use sensors to monitor the pouring of oil and salt, and issue reminders when preset values are reached. Additionally, some devices with basic intelligent control functions can dispense oil and salt in fixed quantities according to user-defined values.
[0003] However, the existing equipment does not have high precision in controlling oil and salt, making it difficult to meet customer needs in terms of taste. Furthermore, it is difficult to accurately control the amount of oil and salt used for different quantities of dishes. In addition, salt easily absorbs water when placed in the kitchen, causing changes in humidity. This makes it even more difficult to control the precision of salt, and the precision requirements for salt are much greater than those for oil. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.
[0027] The following description, in conjunction with the accompanying drawings and embodiments, details the kitchen oil and salt control device.
[0028] like Figure 1-4 As shown, a kitchen oil and salt control device includes a housing and a food weighing scale, an oil control mechanism, and a salt control mechanism electrically connected to a controller. The food weighing scale, fixed to the top of the housing, is an electronic scale that accurately weighs the food. After identification by a microcontroller, it quickly calculates the precise amount of oil and salt needed. The oil and salt control mechanisms are both fixed inside the housing. The controller uses a microcontroller embedded system as the core control unit of the entire device. It is responsible for receiving information from the AI voice interaction module, the button input module, and the sensors, processing and analyzing the data, and controlling the operation of the oil and salt storage and output modules according to a preset algorithm. It has a built-in database of oil and salt usage for various dishes and can accurately calculate the required amount of oil and salt based on the number of diners and the quantity of dishes input by the user. For a detailed control process principle, please refer to the appendix. Figure 4 .
[0029] The oil control mechanism has an oil outlet pipe extending from the front of the outer casing, and the salt control mechanism has a salt outlet pipe extending from the front of the outer casing. The salt control mechanism includes a salt storage box, a screw extruder, and a humidity control component. The salt outlet pipe is connected to the salt storage box, and the screw extruder is rotatably mounted on the salt storage box, with its output end extending into the salt outlet pipe. The humidity control component is fixed to the salt storage box to control the internal humidity. The independent dual-outlet design avoids cross-contamination between oil and salt. The screw extruder achieves quantitative salt dispensing through mechanical extrusion, and the humidity control component maintains a dry environment inside the salt storage box. This improves hygiene and safety, prevents salt particles from becoming damp and clumping, and ensures smooth dispensing.
[0030] Specifically, the screw extruder includes a drive motor and an extrusion screw. The extrusion screw passes through the salt storage box from back to front. The drive motor is fixed to the rear side of the salt storage box, and its output end is connected to the extrusion screw. The drive motor controls the start, stop, and speed of the extrusion screw through forward and reverse rotation, achieving precise delivery of salt particles. The motor torque is adjustable to adapt to the delivery requirements of salt with different particle sizes, reducing the risk of jamming. The amount of salt extruded can be precisely controlled based on the motor's rotation angle.
[0031] Furthermore, the extrusion screw is equipped with a pre-extrusion section and a post-dispersion section. The pre-extrusion section uses a trapezoidal thread, and the salt outlet pipe has a horizontal section and an inclined section. The inclined section discharges material at an angle downwards, and the trapezoidal thread extends into the horizontal section, with its outer wall fitting against the inner wall of the horizontal section. The post-dispersion section is equipped with several flexible dispersing teeth. The trapezoidal thread and the pipe wall form a sealed conveying channel to prevent salt particle backflow; the inclined section utilizes gravity to assist in material discharge; and the dispersing teeth break down the agglomerated structure of the salt particles. This achieves precise single-particle-level conveying with a salt output error of ≤0.1g, and the post-dispersion section design reduces maintenance frequency.
[0032] The bottom surface of the salt storage box is inclined, gradually rising as it moves rearward from the horizontal pipe section. A conical opening is provided at the connection point of the horizontal pipe section, ensuring that salt is evenly collected there before being conveyed to the horizontal pipe section via the extrusion front section. The inclined bottom surface and the conical opening form a salt particle guiding system, ensuring no dead corners or residue within the salt storage box. Salt particle utilization reaches 99%, reducing cleaning workload, and the conical opening structure enhances the material gripping ability of the extrusion front section.
[0033] The humidity control component includes a heating plate and a salt humidity sensor. The heating plate is located on both sides of the salt storage box, and the salt humidity sensor extends into the interior of the salt storage box. The controller is electrically connected to both the heating plate and the salt humidity sensor. The salt humidity sensor monitors the salt humidity in real time. When the humidity exceeds a threshold, the controller activates the heating plate for intermittent dehumidification. This controls the relative humidity inside the salt storage box to below 40%, extending the shelf life of the salt to 18 months and preventing short circuits in electronic components due to moisture. It also ensures that the salt does not easily clump. A weighing scale is installed at the bottom of the salt storage box, and the signal output terminal of the weighing scale is electrically connected to the controller. The weighing scale uses a high-precision pressure sensor to provide real-time feedback on the remaining salt level. When the salt level is lower than a preset value, the controller issues a salt replenishment reminder through the display module to avoid interrupting cooking. The weighing scale provides real-time feedback on the amount of salt extruded during the extrusion of the salt, allowing for timely correction.
[0034] A preferred technical solution is that the oil control mechanism includes an oil suction pump, an oil delivery pipe, and a flow metering valve. The oil suction pump is directly mounted on the oil drum, and the oil delivery pipe is connected to the oil suction pump. One end of the oil delivery pipe extends into the oil drum, and the other end is connected to the flow metering valve. The output end of the flow metering valve is connected to the oil outlet pipe. The oil suction pump is a food-grade diaphragm pump, and the flow metering valve measures the oil volume using a turbine-type sensor. The oil dispensing accuracy reaches 0.1 ml, and the detachable design of the pump body and the oil drum facilitates the replacement of oil drums of different sizes.
[0035] Optional features include a control console located on the upper front side of the outer casing, comprising a display module and a button input module, both electrically connected to the controller. The control console serves as a human-machine interface, supporting the storage and retrieval of preset recipe parameters. Users can quickly select between "light," "standard," and "rich" modes via buttons, while the display module shows real-time data on oil and salt usage. The button input module provides a traditional operating method, allowing users to input the number of diners and the quantity of dishes. The button input module is connected to a microcontroller, transmitting user input information for processing. The display module uses an LCD screen to show user input information, current oil and salt output, and daily and monthly oil and salt intake statistics. Users can intuitively understand the device's operating status and their own oil and salt intake through the display module.
[0036] An optional feature is that an AI voice interaction module is also provided on the front side of the outer casing. This module includes a microphone and a speaker, both electrically connected to the controller. The AI voice interaction module employs advanced voice recognition technology to accurately recognize user voice commands. Users can inform the device of the number of diners and the quantity of dishes via voice, and the AI voice control module transmits the recognized information to the microcontroller. Simultaneously, this module also features voice prompts, providing real-time updates on the current operating status and oil / salt output during device operation.
[0037] An optional feature is that a proximity sensor switch is provided on the front side of the outer casing, located behind the oil outlet pipe and the salt outlet pipe. The infrared sensor switch detects the approach of a spatula or spoon and automatically activates the corresponding dispensing mechanism. This avoids accidental operation, with a dispensing response time of ≤0.3 seconds, improving cooking efficiency.
[0038] The process is as follows: the user inputs the number of diners and the quantity of dishes via AI voice control or button input, and the dishes are weighed. The microcontroller, based on the user's input and the dish weight, retrieves the corresponding oil and salt dosage from its built-in database and performs precise calculations. The microcontroller then controls the flow metering valve and screw extruder to open, initiating oil and salt dispensing. Simultaneously, the output of oil and salt is monitored in real time, and the data is fed back to the microcontroller. Based on the feedback data, the microcontroller adjusts the oil pump's operation and the angle of the drive motor in real time to ensure that the oil and salt output matches the preset values. When the output reaches the set value, the microcontroller shuts down the device. During operation, the AI voice control module provides real-time voice prompts, and the display module shows the current operating status and oil and salt output. The microcontroller records the oil and salt output for each transaction and calculates daily and monthly oil and salt intake. Users can view these statistics through the display module.
