Description

Technical Field

[0001] This invention relates to the field of coffee machine technology, and more particularly to an intelligent hot water device for a drip coffee robot. Background Technology

[0002] People have applied electronic technology to coffee machines, enabling automatic control of the entire coffee brewing process, including grinding, tamping, filling, brewing, and removing residue.

[0003] Existing coffee machines still have the following drawbacks when in use:

[0004] 1. In daily life, people need to use hot water of various temperatures, which traditional coffee machines can no longer meet. Existing drip coffee equipment does not have intelligent learning capabilities and cannot meet personalized configuration needs.

[0005] To address the aforementioned issues, this invention proposes an intelligent hot water device for a drip coffee robot. Summary of the Invention

[0006] This invention provides an intelligent hot water device for a drip coffee robot, which solves the shortcomings of existing technologies. In daily life, people need to use hot water of various temperatures, which traditional coffee machines cannot meet. Existing drip coffee equipment also lacks intelligent learning capabilities and cannot meet personalized configuration needs.

[0007] This invention provides the following technical solution:

[0008] The smart hot water device for the drip coffee robot includes hardware, mobile application software, and communication components.

[0009] The hardware component includes an anti-backflow component, a flow rate control pump, a heating system, and an anti-backflow outlet vent. The anti-backflow outlet vent is located above the heating system and is connected to the heating system. The flow rate control pump is located on one side of the heating system and is connected to the heating system. The anti-backflow component is located on one side of the flow rate control pump and is connected to the flow rate control pump.

[0010] The application software uses image recognition methods and image data extraction technology. It uses fast convolutional image recognition technology to perform corresponding image recognition. Based on the pre-made water pouring image as a benchmark, it uses convolutional neural network technology to identify the number of segments of coffee making, the time of each segment of water pouring, and the time interval between each segment of water pouring in the video.

[0011] The communication component uses a wireless Bluetooth communication module to enable the transmission of configuration and control information between the smart hot water device of the drip coffee robot and the mobile application.

[0012] In one possible design, the hardware component further includes a transformer and voltage regulator module, an APP terminal, a control module, and an algorithm module. The algorithm module is connected to the transformer and voltage regulator module, the wireless Bluetooth communication module is connected to the algorithm module, the control module is connected to the algorithm module, and the APP terminal is connected to the wireless Bluetooth communication module.

[0013] In one possible design, the heating system includes a heating tube, an inlet, an outlet, and a signal interface. The inlet is located on the bottom side of the heating tube and is connected to the heater. The outlet is located on the top side of the heater and is connected to the heater. The signal interface is located on one side of the heater.

[0014] In one possible design, the heating system further includes an outlet temperature sensor and an inlet temperature sensor, with the outlet temperature sensor located at the top of the heater and the inlet temperature sensor located at the bottom of the heater.

[0015] In one possible design, the hardware component also includes buttons and indicator lights, both of which are connected to the algorithm module.

[0016] In one possible design, the controlled flow rate water pump includes an inlet, a drain, an input port, and a pump interface. The input port and the pump interface are both located on the controlled flow rate water pump. The inlet is located on one side of the bottom of the controlled flow rate water pump, and the drain is located on the other side of the bottom of the controlled flow rate water pump.

[0017] In one possible design, a food-grade heat-resistant one-way valve is provided at the rear end of the backflow prevention outlet vent.

[0018] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.

[0019] In this invention, the water tank is self-locking, and the anti-backflow component only opens normally when the water tank is placed. After the water tank is removed, it automatically closes to prevent water from overflowing from the inlet due to pressure difference backflow in the heating tube. The flow rate control pump operates according to the PWM waveform at the input port and controls the water flow rate according to the PWM duty cycle, so that the anti-backflow outlet vent discharges water at the required flow rate corresponding to the calculation result of the algorithm module. When the power is first turned on, there is no water in the heating tube. After the flow rate control pump starts working, the resistance value calculated at the input port determines the current placement position of the water tank. The working time of the flow rate control pump for the first water filling is determined according to the placement position of the water tank to ensure that the heating tube is full of water.

[0020] In this invention, a food-grade heat-resistant one-way valve is placed at the rear end of the anti-backflow water outlet vent. This prevents water in the heating tube from flowing back due to pressure difference when the water pump is not working, thus preventing dry burning of the heating tube due to lack of water during heating. A preheating method is used for water dispensing, instead of the traditional method. The traditional method involves dispensing water at a fixed flow rate, then heating at maximum power, and then dynamically adjusting the power to stabilize the water temperature. In this invention, the corresponding temperatures are first obtained from the inlet and outlet temperature sensors. Then, the heating time is calculated based on the algorithm module's calculation results. The heating tube is preheated to the target temperature before water is dispensed. Furthermore, the heating power required to maintain the outlet water temperature is calculated based on the PID coefficient, and heating continues.

[0021] In this invention, since the target temperature may be set to boiling water, heating will heat the air and water contained in the water to 100°C, forming water vapor. Therefore, there are vents around the anti-backflow water outlet. Due to pressure, the gas in the upper part of the water outlet chamber is introduced into the vents around the water outlet through three conduits. Through testing experiments on the relationship between flow rate and heating power, a quadratic curve relationship is found. This relationship requires multiple experiments. Temperature sensors at the water outlet and water inlet record the relationship between heating power, water temperature, and flow rate. Based on the measured values, a quadratic curve is obtained, the quadratic curve parameters are calculated, and the calculation formula is derived. Then, based on the parameters, the heating power required to achieve the desired water temperature at the corresponding flow rate is deduced. Based on the inlet water temperature, flow rate, and heating power, the curve parameters are obtained. The heating power is calculated using the quadratic curve and the target temperature. Preheating is performed, and during the water outlet process, heating continues. The heating power is controlled by a chopper waveform according to the water flow rate. Then, the heating coefficient is dynamically adjusted using a PID coefficient to keep the water temperature at the set temperature and maintain it.

[0022] In this invention, the process of brewing drip coffee is recorded using a mobile phone. An app then uses AI image recognition technology to analyze the brewing process and extract key data, such as the number of water dispensing cycles, dispensing time, intervals, and water temperature. These parameters are saved in the mobile application and modified to correspond to a specific water dispensing mode. Users can select the appropriate mode to brew coffee. The recorded video is analyzed by the app using AI to obtain parameters such as dispensing time, flow rate, and temperature. A rapid object recognition method is used to analyze the video to determine the number of water dispensing cycles, dispensing time, and intervals used by the barista in the video. These parameters are stored as a coffee brewing style in the app. The app then connects to the instant hot water dispenser's Bluetooth module, transmitting the dispensing cycle number, dispensing time, and other parameters via Bluetooth. The smart hot water device then adds a new mode. Users can select this mode to brew coffee, and the number of dispensing cycles, dispensing time, and intervals will match those in the video. To create a new style, users can also use the APP terminal to directly send commands to the wireless Bluetooth communication module of the instant hot water dispenser to perform actions such as adjusting the water temperature, adjusting the water volume, dispensing water directly, and turning the child lock on and off, truly realizing the function of remote control. The APP terminal has an online store unit, which can be used by customers to browse product information, generate an order after placing an order, and finally complete the transaction. After the transaction is completed, the order information is transmitted to the display interface via the Internet.

[0023] In this invention, the control terminal connects to the various functional modules of the water heater via a wireless communication module, enabling remote control of the water heater. On one hand, the intelligent control system automatically collects the necessary data through various devices on the water heater and displays it intuitively on the human-machine interface of the control terminal APP, thus achieving intelligent monitoring of the water heater. On the other hand, operators can use the settings function on the APP control terminal to set various styles of tea, coffee, milk powder, etc., design the brewing temperature, and set the water output.

[0041] The hardware includes an anti-backflow component 400, a flow rate control pump 300, a heating system 100, and an anti-backflow outlet vent 200. The anti-backflow outlet vent 200 is located above the heating system 100 and is connected to the heating system 100.

[0042] The application software uses image recognition methods and image data extraction technology. It employs fast convolutional image recognition technology to perform corresponding image recognition. Using pre-made water pouring images as a benchmark, it uses convolutional neural network technology to identify the number of segments of coffee brewing in the video, the time of each segment of water pouring, and the time interval between each segment of water pouring.

[0043] The communication section uses a wireless Bluetooth communication module 040 to enable the transmission of configuration and control information between the smart hot water device of the drip coffee robot and the mobile application.

[0044] Example 2

[0045] Reference Figure 1-8 The smart hot water device for brewing drip coffee robots includes hardware, mobile application software, and communication components.

[0046] The hardware components include an anti-backflow component 400, a flow rate control pump 300, a heating system 100, and an anti-backflow outlet vent 200. The anti-backflow outlet vent 200 is equipped with a food-grade heat-resistant one-way valve at its rear end, which prevents water in the heating element from flowing back due to pressure difference when the pump is not operating, thus preventing dry burning during heating. The anti-backflow outlet vent 200 is located above and connected to the heating system 100. The flow rate control pump 300 is located on one side of the heating system 100 and connected to it. The anti-backflow component 400 is located on one side of the flow rate control pump 300 and connected to it. The system is interconnected, with a self-locking water tank and an anti-backflow component 400 that only opens when the water tank is placed in the tank and automatically closes after removal to prevent water from overflowing from the inlet 101 due to pressure difference. The hardware also includes a voltage regulator module 010, an app terminal 060, a control module 050, and an algorithm module 090. The algorithm module 090 is connected to the voltage regulator module 010, the wireless Bluetooth communication module 040 is connected to the algorithm module 090, the control module 050 is connected to the algorithm module 090, and the app terminal 060 is connected to the wireless Bluetooth communication module 040. The heating system 100 includes a heating element. The system includes an inlet 101, an outlet 102, and a signal interface 104. The inlet 101 is located on the bottom side of the heating tube and connected to the heater. The outlet 102 is located on the top side of the heater and connected to the heater. The signal interface 104 is located on one side of the heater. The heating system 100 also includes an outlet temperature sensor 105 and an inlet temperature sensor 106. The outlet temperature sensor 105 is located on the top of the heater, and the inlet temperature sensor 106 is located on the bottom of the heater. The system first obtains the corresponding temperatures based on the inlet temperature sensor 106 and the outlet temperature sensor 105, and then calculates the results based on the algorithm module 090. The heating time is calculated, the heating element is preheated to the target temperature, and then water is discharged. The heating power to maintain the water temperature is calculated based on the PID coefficient, and heating continues. The hardware also includes a button 020 and an indicator light 030, both of which are connected to the algorithm module 090. The flow rate control pump 300 includes an inlet 301, a drain 302, an input port 303, and a pump interface 304. The input port 303 and the pump interface 304 are both located on the flow rate control pump 300. The inlet 301 is located on one side of the bottom of the flow rate control pump 300, and the drain 302 is located on the other side of the bottom of the flow rate control pump 300.

[0047] The application software uses image recognition methods and image data extraction technology. It employs fast convolutional image recognition technology to perform corresponding image recognition. Using pre-made water pouring images as a benchmark, it uses convolutional neural network technology to identify the number of segments of coffee brewing in the video, the time of each segment of water pouring, and the time interval between each segment of water pouring.

[0048] The communication section uses a wireless Bluetooth communication module 040 to transmit configuration and control information between the smart hot water device of the instant hot water dispenser and the mobile application. The APP terminal 060 connects to the wireless Bluetooth communication module 040 of the instant hot water dispenser, transmitting parameters such as water flow rate and dispensing time to the instant hot water dispenser via Bluetooth protocol. This adds a new mode to the smart hot water device. Users can select this mode to brew coffee, and the brewing flow rate, dispensing time, and interval will match those in the video, creating a new style. Users can also directly send commands from the APP terminal 060 to the wireless Bluetooth communication module 040 of the instant hot water dispenser to perform actions such as adjusting water temperature, adjusting water volume, direct water dispensing, and turning the child lock on / off, truly achieving remote control functionality.

[0049] However, as is well known to those skilled in the art, the working principles and wiring methods of the wireless Bluetooth communication module 040, indicator light 030, flow rate control pump 300, voltage regulator module 010, APP terminal 060, control module 050, algorithm module 090, outlet temperature sensor 105, and inlet temperature sensor 106 are commonplace and belong to conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0050] The working principle and usage process of this technical solution are as follows: the water tank is self-locking and the anti-backflow component 400 only opens normally when the water tank is placed and closes automatically after the water tank is removed to prevent the water in the heating tube from overflowing from the inlet 101 due to pressure difference.

[0051] like Figure 2 As shown, the flow rate control pump 300 operates according to the PWM waveform of the input port 303, and controls the water flow rate according to the PWM duty cycle, so that the anti-backflow water outlet 200 discharges water according to the required flow rate corresponding to the calculation result of the algorithm module 090.

[0052] like Figure 2 As shown, there is no water in the heating tube when it is first powered on. After the flow rate pump 300 starts working, the resistance value calculated by the input port 303 determines the current placement position of the water tank. Based on the placement position of the water tank, the working time of the flow rate pump 300 for the first water filling is determined to ensure that the heating tube is full of water.

[0053] Furthermore, a food-grade heat-resistant one-way valve is placed at the rear end of the anti-backflow water outlet 200, which can prevent water in the heating tube from flowing back due to pressure difference when the water pump is not working, thus preventing dry burning due to the absence of water in the heating tube during heating.

[0054] Instead of the traditional method, this application uses a preheating method for water dispensing. The traditional method involves dispensing water at a fixed flow rate, then heating it at maximum power, and then dynamically adjusting the power to stabilize the water temperature. In contrast, this application first obtains the corresponding temperatures from the inlet temperature sensor 106 and the outlet temperature sensor 105, then calculates the heating time based on the calculation results of the algorithm module 090, preheats the heating element to the target temperature, and then dispenses water. Furthermore, it calculates the heating power to maintain the outlet water temperature based on the PID coefficient and continues heating.

[0055] like Figure 2 Since the target temperature may be set to boiling water, heating will heat the air and water contained in the water to 100°C, forming water vapor. Therefore, there are exhaust ports around the anti-backflow water outlet exhaust port 200. Due to pressure, the gas in the upper part of the water outlet chamber is introduced into the exhaust ports around the water outlet through three pipes.

[0056] Through experimental testing of the relationship between flow rate and heating power, a quadratic curve relationship was determined. This relationship required multiple experiments. Temperature sensors 105 at the outlet and 106 at the inlet recorded the relationship between heating power, water temperature, and flow rate. Based on the measured values, a quadratic curve was obtained, its parameters were calculated, and a calculation formula was derived. Then, based on these parameters, the heating power required to achieve the desired water temperature at the corresponding flow rate was deduced.

[0057] Based on the inlet water temperature, flow rate, and heating power, curve parameters are obtained. The heating power is calculated using a quadratic curve and the target temperature. Preheating is performed, and heating continues during the water outlet process. The heating power is controlled by a chopper waveform according to the water flow rate. Then, the heating coefficient is dynamically adjusted using a PID coefficient to keep the water temperature at the set temperature and maintain it.

[0058] The process of brewing coffee with a drip bag is recorded on a mobile phone. The APP terminal 060 uses AI image recognition technology to analyze the brewing process and extract key data, such as the number of water infusions, water infusion time, interval time and water temperature. These parameters are saved in the mobile application software and modified to the corresponding water infusion mode. Users can select the appropriate mode to brew coffee.

[0059] Using videos recorded on a mobile phone, the APP terminal 060 performs AI intelligent analysis to obtain parameters such as water dispensing time, flow rate, and temperature. Through rapid object recognition, the video is analyzed to determine the number of water dispensing segments, dispensing time, and intervals used by the barista in the video when brewing coffee. These parameters are stored as a coffee brewing style in the APP terminal 060. Then, the APP terminal 060 connects to the wireless Bluetooth communication module 040 of the instant hot water dispenser, transmitting the water dispensing segments, dispensing time, and other parameters to the instant hot water dispenser via Bluetooth. The smart water heater will then add a new mode. Users can select this mode to brew coffee, and the number of water dispensing segments, dispensing time, and intervals will match those in the video, creating a new style.

[0060] Alternatively, the APP terminal 060 can be used to send commands directly to the wireless Bluetooth communication module 040 of the instant hot water dispenser to perform actions such as adjusting the water temperature, adjusting the water volume, dispensing water directly, and turning the child lock on and off, thus truly realizing the function of remote control.

[0061] The APP terminal 060 has an online shopping mall unit, which allows customers to browse product information, place orders, generate orders, and finally complete transactions. After the transaction is completed, the order information is transmitted to the display interface via the Internet.

[0062] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. In the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
