Description

Technical Field

[0001] The present invention relates to the technical field of water dispensers, and in particular to a control method of a multifunctional water dispenser and the water dispenser. Background Art

[0002] At present, most water dispensers only have hot and cold functions, or a single sparkling water function. The functions are relatively simple and cannot fully meet the needs of users. They use steam compression to cool; due to the presence of components such as compressors and condensers, the product size is relatively large; secondly, to make sparkling water, you need to press the gas cylinder by hand and take the sparkling water from the water bottle, which is relatively inconvenient for users to use. Moreover, if the external water bottle is removed and left for a long time, it will affect the taste of the sparkling water and waste carbon dioxide gas. At present, most water dispensers have a single function and can only achieve two water outlet methods, resulting in a low degree of intelligence of the water dispenser and a poor user experience.

[0003] Prior art 1, application number: CN 202410607788.6 discloses a water dispenser, including: a hot tank assembly and an inlet and outlet waterway plate, the hot tank assembly has a heating chamber and a water inlet joint and a first water outlet joint connected to the heating chamber, a heating element is provided in the heating chamber, the hot tank assembly is connected to the inlet and outlet waterway plate and is located below the inlet and outlet waterway plate, a water diversion pool is formed on the upper surface of the inlet and outlet waterway plate, a water supply channel and a water outlet channel are formed in the inlet and outlet waterway plate, the water supply channel is located below the water diversion pool, a water supply joint and a second water outlet joint are provided on the inlet and outlet waterway plate, the water supply joint is connected to the water diversion pool through the water supply channel and is connected to the water inlet joint, and the first water outlet joint is connected to the second water outlet joint. Although the integration of the inlet and outlet waterway plate can be improved to reduce the number of parts of the water dispenser, the assembly steps of the water dispenser can be better simplified, which is conducive to improving the assembly efficiency of the water dispenser. However, no improvement has been made to the water output specifications of the water dispenser, resulting in a relatively single water output function, which affects the intelligence level of the water dispenser.

[0004] Prior art 2, application number: CN 202410607722.7 discloses a water outlet waterway assembly and a water dispenser, including a main body, the main body having a flow channel, a first interface and a second interface, one of the first interface and the second interface is configured to connect to the water inlet waterway assembly, and the other is configured to connect to the water outlet assembly, and the flow channel connects the first interface and the second interface. Although water can be transported from the water inlet waterway assembly to the water outlet assembly by arranging the water outlet waterway assembly between the water inlet waterway assembly and the water outlet assembly, and the structure is simple and easy to assemble. However, its structure is relatively simple, and no real improvement is made to the structure related to the water outlet, resulting in the water outlet specifications of the water dispenser needing to be further improved and enhanced.

[0005] Prior art three, application number: CN 202410927634.5 discloses a water outlet control method, device, water dispenser and medium for a water dispenser, including: obtaining the target water temperature, and determining the first energy parameter at the current water outlet moment; determining the second energy parameter at the current water outlet moment according to the size relationship between the total water outlet and the set volume; setting the volume to be the volume of residual water in the first water path and the second water path after the last water outlet; controlling the first water flow rate of the first water path and the second water flow rate of the second water path according to the first energy parameter and the second energy parameter. Although it can solve the influence of the output of residual water in the water dispenser on the water temperature in the water receiving container, thereby realizing the precise control of the water temperature in the water receiving container, so that the water temperature in the water receiving container can reach the target water temperature. However, only the adjustment of the water temperature is realized, resulting in the single control function of the water dispenser, which affects the development and improvement of functional intelligence.

[0006] At present, the prior art 1, prior art 2 and prior art 3 have the problem that the water output control method of the water dispenser is relatively simple, and the water output specifications are mainly cold and hot, so that the intelligence level of the water dispenser needs to be further improved. Therefore, the present invention provides a control method and a water dispenser of a multifunctional water dispenser. Summary of the invention

[0007] In order to solve the above technical problems, the present invention provides a method comprising the following steps:

[0008] A control method for a multifunctional water dispenser comprises the following steps:

[0009] The user manipulates the water production selection function on the control interface, and after the manipulation is completed, the controller receives an operation termination instruction; the controller triggers the user demand program according to the termination instruction, and the user demand program identifies the manipulation selection function to obtain the user's purpose demand;

[0010] According to the purpose demand, the corresponding water production mode is called, the water production mode starts the corresponding execution structure, and the working water production is carried out according to the preset water production program of the water production mode;

[0011] Among them, there are three water production modes. The first water production mode includes cold water and normal temperature water, the second water production mode includes hot water, and the third water production mode includes normal temperature sparkling water and cold sparkling water;

[0012] After the water production is completed, the capacity of the water container is obtained through the image acquisition device, and the flow rate of the water pump is calculated based on the capacity; when the water container reaches the preset capacity, the controller stops discharging water and sends a reminder to the user to take away the water container.

[0013] Optionally, the process of obtaining the user's purpose needs includes the following steps:

[0014] The specific content of the water production selection function is obtained, the element information corresponding to the specific content is extracted, and the element information is structured, and a node is established for each water production selection function in the user demand program; according to the association relationship in the node, the relationship between the water production selection function and the water production mode is established, and a functional relationship diagram is generated based on the nodes and relationships; wherein the specific content includes cold water, hot water, normal temperature water, normal temperature bubble water, cold water bubble and temperature;

[0015] Record the water production selection function input by the user in real time, extract element information from the record through preprocessing, distinguish the element information, and obtain the purpose demand and temperature set; construct the corresponding code according to the purpose demand, and find the corresponding water production model from the functional relationship diagram;

[0016] The temperature and water-making mode in the set are input into the controller through the data interface; the controller determines the temperature and water-making mode, and starts the water-making mode if they meet the water-making procedure.

[0017] Optionally, the process of performing working water production according to the preset water production program of the water production mode includes the following steps:

[0018] The temperature output by the controller and the water making mode corresponding to the water making program are obtained, and the target water making mode starting program is started according to the temperature and the water making mode. The target water making mode starting program first selects a water making mode from the functional relationship diagram according to the temperature content;

[0019] After selecting a water production mode, confirm whether there are bubbles in the target demand. If there are bubbles, directly select the water production mode as the third water production mode, and confirm whether it is room temperature bubble water or cold bubble water according to the temperature content; if there are no bubbles, confirm whether heating is required according to the temperature content, and if heating is required, select the water production mode as the second water production mode;

[0020] When the target demand does not include bubbles and heating, the cold water or normal temperature water mode of the first water production mode is confirmed to be started according to the temperature content.

[0021] Optionally, the selection process of the third water production mode includes the following steps:

[0022] The logic judgment module built into the controller performs logic judgment based on the detection results of the target requirements. If bubbles are detected, the logic judgment module triggers the mode switching instruction; the logic judgment module generates the mode switching instruction, and the mode switching instruction includes the identification information of the target mode and the switching timestamp;

[0023] The controller calls the preset mode switching logic and responds to the mode switching instruction. The state transition table of the mode switching logic records the transition path and operation steps from the current mode to the target mode.

[0024] According to the state transition table, the controller executes the state transition from the current mode to the third water production mode, closes the execution structure of the current mode and initializes the execution structure of the third water production mode.

[0025] Optionally, the process of generating a mode switching instruction by the logic judgment module includes the following steps:

[0026] After the bubble detection is completed, the logic judgment module starts the logic operation, matches the detected bubble state with the preset conditions, and determines whether the conditions for switching to the third water production mode are met; if the switching conditions are met, the logic judgment module generates a switching decision and prepares to generate a mode switching instruction;

[0027] The logic judgment module calls the preset mode switching instruction template, which includes the basic structure and necessary fields; fills the identification information of the third water production mode into the mode switching instruction template, adds the current timestamp, and records the time when the instruction is generated; after generating the instruction, checks whether all fields and information in the mode switching instruction have been filled;

[0028] The logic judgment module activates the communication interface of the controller, transmits the generated mode switching instruction to the mode switching logic module, and waits for a confirmation signal from the mode switching logic module.

[0029] Optionally, the process of determining whether the condition for switching to the third water production mode is met comprises the following steps:

[0030] The bubble detection in the target demand is compared with the demand parameters of the third water production mode. If there are bubbles, the water volume and temperature are matched. If not, other modes are used. Boolean operators are used to combine multiple parameter conditions. The first-level Boolean operation is performed on the water flow and temperature to determine whether they are within the range of the third water production mode.

[0031] Obtain the required temperature of the bubble water in the target demand, obtain the output temperature of the bubble, and perform a second-level Boolean operation with the bubble temperature range required by the third water production mode; analyze the distribution of bubbles corresponding to the output temperature in different areas, and use Boolean operations to determine whether it meets the requirements of the third water production mode;

[0032] The Boolean operation results of the first level and the second level are comprehensively matched, and multi-level Boolean operations are used to determine whether the switching conditions of the third water production mode are met.

[0033] Optionally, the process of confirming the start of the cold water mode or the normal temperature water mode of the first water production mode comprises the following steps:

[0034] Compare the temperature in the target demand with the preset temperature range of the first water production mode, the temperature range of the cold water mode is set between 0°C and 10°C, and the temperature range of the normal temperature water mode is set between 10°C and 25°C;

[0035] When the detected temperature is lower than 10℃, the cold water mode is automatically selected and the water source is directly delivered to the outlet through the cold water pipe; when the detected temperature is between 10℃ and 25℃, the normal temperature water mode is selected and the water source is delivered to the outlet through the normal temperature water pipe;

[0036] After selecting the corresponding mode, start the first water production mode and begin the water production process.

[0037] Optionally, the process of calculating the flow rate of water outflow from the water pump according to the capacity includes the following steps:

[0038] Obtain the geometric parameters of the water container, including height, diameter and wall thickness, use ultrasound to detect the surface height of the liquid in the container in real time, convert it into a digital signal through an analog-to-digital converter, and calculate the target capacity;

[0039] According to the geometric parameters of the container, combined with the real-time detection of the liquid surface height, the liquid volume in the current container is calculated; a fluid mechanics model is established, including the geometric parameters of the container, the density and viscosity of the water, and the gravitational acceleration factors, and a numerical solution is performed through finite element analysis;

[0040] According to the fluid mechanics model and the target capacity, the flow rate calculation formula is applied, combined with the current capacity and the target capacity, to calculate the required flow rate; the controller adjusts the flow rate in real time according to the current capacity and the target capacity.

[0041] Optionally, the process of adjusting the flow rate in real time includes the following steps:

[0042] Obtain the liquid capacity in the current container. The controller reads the liquid capacity in real time, compares it with the target capacity, and calculates the difference;

[0043] Determine how to adjust the flow rate based on the difference. Calculate the proportional control output based on the difference through the PID control algorithm. Calculate the integral of the difference to get the integral control output. Calculate the rate of change of the difference to get the differential control output. Add the outputs of the proportional, integral and differential controls to get the total output of the controller. Adjust the output signal based on the difference and its changing trend.

[0044] The signal output by the controller will be transmitted to the actuator, thereby changing the flow rate of the fluid; after adjusting the flow rate, the current liquid capacity is read again and the new data is fed back to the controller.

[0081] S201: obtaining the temperature output by the controller and the water production mode corresponding to the water production program, and starting the target water production mode starting program according to the temperature and the water production mode. The target water production mode starting program first selects a water production mode from the functional relationship diagram according to the temperature content;

[0082] S202: After a water production mode is selected, it is confirmed whether there are bubbles in the target demand. If there are bubbles, the water production mode is directly selected as the third water production mode, and normal temperature bubble water or cold bubble water is confirmed according to the temperature content; if there are no bubbles, it is confirmed whether heating is required according to the temperature content, and if heating is required, the water production mode is selected as the second water production mode;

[0083] S203: When the target demand does not include bubbles and heating, confirming to start the cold water mode or normal temperature water mode of the first water making mode according to the temperature content.

[0084] The working principle and beneficial effects of the above technical solution are as follows: the present embodiment first obtains the temperature output by the controller and the water production mode corresponding to the water production program, and starts the target water production mode start-up program according to the temperature and the water production mode. The target water production mode start-up program first selects a water production mode from the functional relationship diagram according to the temperature content; secondly, after selecting a water production mode, confirm whether there are bubbles in the target demand.
