[0052] The faucet assembly is installed on the refrigerator cabinet 1. The faucet assembly includes two faucet bodies 2, which are a cold milk outlet 142 and a hot milk outlet 141, respectively. It should be noted that a milk dispensing temperature sensor T5 is installed at the front end of the hot milk outlet 141.

[0053] Display component 3 is mounted on the refrigerator cabinet 1.

[0054] It should be noted that display component 3 is supported by a screen bracket, which is fixed to the refrigerator all-in-one countertop. The industrial control screen all-in-one is assembled inside the screen bezel and fixed to the screen bracket with screws. A speaker is installed inside the screen bracket and connected to the industrial control screen all-in-one for sound playback. A USB port is located at the bottom of the screen bracket, connected internally to the screen all-in-one, with the interface protruding from the screen bracket. A rubber protective cover is provided. The USB port is used for data transmission between the industrial control screen all-in-one and other media.

[0055] The industrial control screen all-in-one machine comes with its own operating system. Human-machine interaction is achieved through the touchscreen display. Communication is possible via wired network, Wi-Fi, and mobile internet. The screen communicates with the lower-level control board via serial communication. Optional industrial control all-in-one screens offer other communication methods and interfaces, including but not limited to USB, RS232, RS485, TTL, GPIO, and microphone.

[0058] It should be noted that the two drain outlets are drain outlet 171 and drain outlet 172, respectively. Drain outlet 171 is connected to the tailwater discharge box below the drain tray 5, and drain outlet 172 is connected to the clean input section 10 and the boiler drain valve V17.

[0059] The refrigerator cabinet 1 contains a cold milk compartment and a hot milk compartment. A raw material level sensor L2 for the cold milk circuit and a raw material level sensor L3 for the hot milk circuit are installed in the cold milk compartment and the hot milk circuit, respectively.

[0060] It should be noted that casters can be installed at the bottom of the refrigerator cabinet for movement. The front of the refrigerator cabinet has an insulated door. The refrigeration unit is located below the left side door. The interior of the refrigerator cabinet is an insulated refrigeration space, where the evaporator and air circulator of the refrigeration unit are located, achieving cooling through airflow.

[0061] Both the cold milk container and the hot milk container are equipped with a raw material scale 4 at the bottom. It can be understood that the raw material scale 4 can be used to obtain the change in liquid volume inside the cold milk container and the hot milk container.

[0062] The raw material extraction module 6 is located on the upper part of the front interior of the refrigerator cabinet 1, and the raw material extraction module 6 is connected to the faucet assembly.

[0063] The cleaning and heating module 7 is located on the back of the refrigerator cabinet 1, and is connected to the raw material extraction module 6.

[0064] The main control module is located inside the back of the refrigerator cabinet 1. The main control module is connected to the display component 3, the faucet component, the raw material extraction module 6, and the cleaning and heating module 7.

[0065] Furthermore, the main control module consists of a power distribution section and a control section. The system power distribution is equipped with a main control leakage protection device. In addition to the independent power supply for the refrigeration unit, power is distributed to each heating branch and power module via the system power supply. Each heating device is controlled by a relay, and a fuse is installed in each heating circuit. The power distribution section is equipped with a switching power supply module to provide low-voltage DC power to the control section and system actuators (pumps, valves, relays, etc.).

[0066] The control section mainly consists of the lower-level control unit, which comprises two control boards. It communicates with the upper-level computer via RS485, receiving commands and sending machine status data. The control boards primarily function according to predefined logic, identifying sensor signals and controlling the actions of system actuators (pumps, valves, relays, etc.) to achieve the set functions.

[0067] In one embodiment of this application, such as Figure 9 As shown, the raw material extraction module 6 includes a cold milk extraction component and a hot milk extraction component.

[0068] The cold milk extraction component is used to extract cold milk ingredients, while the hot milk extraction component is used to extract hot milk ingredients. It should be noted that the cold milk extraction component ultimately transfers the extracted cold milk ingredients to the cold milk / cold milk beverage outlet, while the hot milk extraction component transfers the extracted hot milk ingredients to the hot milk / cold milk beverage outlet.

[0069] It should be noted that a cold air delivery pipe 15 can be installed at the front end of the cold milk / cold milk beverage outlet and the hot milk / milk beverage outlet to cool them down and keep the milk fresh.

[0070] In one embodiment of this application, such as Figure 9As shown, the cold milk extraction assembly includes a cold milk extraction pipe 81, a cold milk raw material extraction pump P2, a cold milk main control valve V02, and a four-way valve 91.

[0071] One end of the cold milk extraction pipe 81 is connected to the cold milk box, and the other end of the cold milk extraction pipe 81 is connected to the input end of the cold milk raw material extraction pump P2; the output end pipe of the cold milk raw material extraction pump P2 is equipped with a cold milk main control valve V02, and the output end of the cold milk raw material extraction pump P2 is connected to the first branch of the four-way valve 91.

[0072] The second branch of the four-way valve 91 is connected to the anti-backflow check valve Y2, the third branch of the four-way valve 91 is connected to the cold milk reverse cleaning and drain valve V04, and the fourth branch of the four-way valve 91 is connected to the cold milk outlet via the clamp valve V06 at point 2 of the faucet body.

[0079] It should be noted that the heat exchanger transfers heat from the hot water to the cold milk through liquid convection, thus heating the milk. The principle is as follows: cold milk enters from the left side of the internal pipes and flows to the right, while hot water enters from the right side and flows to the left. The water completely surrounds the milk pipes. After flowing in opposite directions through the pipes, the milk becomes hot and flows out from the right side, while the hot water becomes lukewarm and flows out from the left side. Furthermore, the milk temperature can be adjusted by changing the hot water temperature, water flow rate, and milk flow rate.

[0080] The water inlet pipe passes through the water inlet and is connected in sequence to the main water inlet valve V18, the pressure reducing valve R2, and then to the first branch of the tee-11.

The quick-connect fitting in the middle of the hot water boiler G1 connects to the hot water inlet valve V15 for boiler water replenishment. A safety valve is connected to the lower part of the hot water boiler G1 to limit boiler pressure.

[0085] The bottom connector of hot water boiler G1 outputs a T-junction, with one branch going to the hot water inlet valve V11 and the other to the boiler drain valve V17. A temperature control switch KC1 is installed on the middle of the boiler body to limit the boiler temperature. The boiler power supply electrode is located at the top of the boiler body, and the exterior of the boiler body is covered with a thermal insulation layer.

[0092] One end of the cold milk circuit reverse cleaning valve V08 and the hot milk circuit forward cleaning valve V07 are respectively connected to two branches of the three-way valve 101, and one end of the hot milk circuit forward cleaning valve V09 and the cold milk circuit forward cleaning valve V10 are respectively connected to two branches of the three-way valve 102.

[0093] The other branches of three-way 3101 and three-way 4102 are connected to the first branches of three-way 5103 and three-way 6104 respectively. The second branch of three-way 5103 is connected to the second branch of three-way 6104. The third branch of three-way 5103 is connected to the steam reversing valve V12.

[0126] The specific working logic of this device is as follows:

[0127] I. Logic of Instant Cold Milk Dispensing

[0128] See Figure 11 This logic is triggered by real-time user actions. Its core is to quickly deliver cold milk and monitor raw material supply in real time to ensure continuous production. The specific process is as follows:

[0129] 1. Trigger Start-up: When the user presses the cold milk dispensing button, the system responds immediately, starts the cold milk raw material extraction pump P2, and simultaneously opens the main cold milk control valve V02 and the clamp valve V06 at the tap, officially opening the passage for cold milk to be transported from the cold milk tank to the cold milk dispensing spout through the pipeline.

[0130] 2. Process Monitoring: During the delivery process, the system uses the pipeline level sensor L2 to detect in real time whether there is cold milk in the pipeline. If L2 detects no liquid, it indicates that the raw material supply is interrupted. The system immediately stops the operation of P2, V02, and V06, the red light on L2 stays on, the cupping failure is recorded, and the amount of milk dispensed is recorded simultaneously. If the user releases the dispensing button, the system also stops all related components and ends the dispensing process.

[0131] 3. Dispensing complete: If L2 detects cold milk before the user releases the button, the cold milk will continue to be dispensed until the user releases the button. The system will then stop running, record the successful dispensing of the cup and the amount of milk dispensed, and the press-to-dispense cold milk process will end.

[0132] II. Logic of dispensing cold milk in fixed quantities

[0133] See Figure 12 Based on the set dispensing volume, precise quantitative dispensing of cold milk is achieved through parameter presets, pipeline status judgment, and timeout monitoring. The specific steps are as follows:

[0134] 1. Parameter setting and initial judgment

[0135] Preset parameters: Key parameters can be set through the software, including cold milk dispensing volume M2, cold milk dispensing timeout TO2, and milk pump operating speed V2 (which can be adjusted on the interface, including default values ​​and adjustment ranges).

[0136] 2. Pipeline Judgment: Upon receiving the quantitative cold milk dispensing instruction, the system determines whether the pipeline is empty based on whether it has been cleaned previously. If empty, the "cold milk filling pipeline logic" is executed first to ensure the pipeline is filled with cold milk to guarantee dispensing accuracy; if the pipeline is not empty, the system directly proceeds to the quantitative delivery stage.

[0137] 3. Quantitative delivery and dual-dimensional monitoring: Start P2 and run at speed V2, turn on V02 and V06, and begin recording the milk output. Simultaneously, perform two monitoring functions: first, use the raw material scale to determine in real time whether the milk output has reached M2; second, monitor whether the dispensing time exceeds TO2.

[0138] 4. Results Processing

[0139] If the milk output reaches M2, immediately stop P2, V02, and V06, and record the successful milk feeding and the output.

[0140] If the dispensing time exceeds TO2, regardless of whether the dispensing volume meets the target, the relevant components will be stopped, and the dispensing failure and dispensing volume will be recorded.

[0141] If L2 detects no liquid during delivery, it stops running, the L2 red light stays on, the cupping failure and output are recorded, and the quantitative cold milk dispensing process ends.

[0142] III. Instant hot milk dispensing logic

[0143] See Figure 13 Based on the existing method of dispensing cold milk immediately, a hot water circulation heating step is added to ensure that the temperature of the hot milk meets the requirements of low-temperature heat exchange technology (heat source temperature <85℃). The specific process is as follows:

[0144] 1. Start-up and Heating Preparation: When the user presses the hot milk dispensing button, the system simultaneously initiates two operations: First, it starts the hot milk raw material extraction pump P3 and runs at the set speed V1 (adjustable via the interface, including default values ​​and adjustment ranges), opening the main hot milk control valve V01 and the pinch valve V05 at the faucet; Second, it starts the hot water circulation logic, with the hot water circulation pump P4 delivering the hot water (temperature <85℃) from the circulating heating boiler G2 to the heat exchanger E1 to prepare for heating cold milk.

[0145] 2. Hot Milk Delivery and Monitoring: Cold milk is drawn through P3, detected by the pipeline level sensor L3, and then enters E1, where it exchanges heat with hot water to become hot milk. The hot milk is then output from the hot milk outlet, and the system begins recording the output. If L3 detects no liquid, it indicates an interruption in the supply process. The system immediately stops P3, V01, and V05, terminates the hot water circulation, the red light on L2 remains constantly lit, and the system records the failure to dispense the milk and the output.

[0146] 3. End of dispensing: When the user releases the hot milk button, the system stops running P3, V01, and V05, ends the hot water circulation, records the successful dispensing of the cup and the amount dispensed, and completes the instant hot milk dispensing process.

[0147] IV. Logic of dispensing hot milk in fixed quantities

[0148] See Figure 14 Combining the heating characteristics of hot milk with the need for quantitative control, precise quantitative dispensing of hot milk is achieved through dual-dimensional regulation of temperature and output. The specific process is as follows:

[0149] 1. Parameter settings and initial preparation

[0150] Preset parameters: Set the hot milk dispensing volume M1, dispensing timeout TO1, milk pump running speed V1 (adjustable via interface), circulating heating boiler G2 set temperature (<85℃), and target hot milk dispensing temperature range (e.g., 60℃-75℃).

[0151] 2. Initial Judgment: After receiving the instruction to dispense hot milk in a quantitative manner, first determine whether the pipeline is empty (based on whether it has been cleaned before). If it is empty, execute the "pre-filling logic for hot milk pipeline" (start P3 to run at low speed, open V01 and V05, start hot water circulation simultaneously, and stop pre-filling after L3 detects liquid). At the same time, check whether the temperature of G2 has reached the set value. If it has not reached the set value, start heating. After reaching the set value, enter the quantitative delivery stage.

[0152] 3. Quantitative Heating and Conveying: Start P3 at speed V1, open V01 and V05, and hot milk enters E1 to exchange heat with the hot water conveyed by G2; P4 continuously runs to maintain hot water circulation, and the heat exchanger outlet temperature sensor T5 monitors the hot milk temperature in real time. The system records the real-time output through raw material scale 4. If the temperature is lower than the target range, the heating power of G2 can be increased or the speed of P3 can be decreased to extend the heat exchange time; if the temperature is higher than the target range, the power of G2 can be decreased or the speed of P3 can be increased to ensure temperature stability.

[0153] 4. Anomaly detection and result processing

[0154] If the output reaches M1 and the temperature meets the requirements, stop P3 and P4, close V01 and V05, and record the successful milk mixing, output, and temperature.

[0155] If the dispensing time exceeds TO1, stop all components, record the dispensing failure, and trigger a timeout alarm.

[0156] If L3 detects no liquid or T5 detects an abnormal temperature (outside the target range), stop operation, record the failure, and prompt the corresponding fault (insufficient raw materials or abnormal temperature).

[0157] V. Automatic Cleaning Logic

[0158] Different cleaning cycles are set according to the usage frequency of hot and cold milk lines. The pipes are cleaned thoroughly by flushing with hot water and steam in both directions. The process includes three parts: cycle control, cleaning of cold milk lines, and cleaning of hot milk lines.

[0159] (a) Automatic cleaning cycle control

[0160] See Figure 15 Parameter settings: Three preset cycle parameters are used: hot milk path with cup stirring automatic cleaning interval TO201 (tentatively set to 30min), hot milk path without cup stirring cleaning interval TO202 (tentatively set to 3.5h), and cold milk path cleaning interval TO203 (tentatively set to 3.5h).

[0161] Periodic trigger: The timer starts after the device is turned on. If hot milk is dispensed, TO201 resets and starts timing again. When TO201 expires, the hot milk path will be cleaned. If there is no hot milk being dispensed, TO202 will start timing and will trigger the hot milk path cleaning. For the cold milk path, TO203 will start timing and will trigger the cold milk path cleaning.

[0162] (ii) Automatic hot water cleaning logic for cold milk tubes

[0163] See Figure 16Preparation phase: After receiving the automatic cleaning command, the L2 red light flashes (cycle 1 second, flashing continuously during cleaning). The system waits for 3 seconds, starts the boiler normal logic, and then switches to hot water output logic. When the temperature sensor T1 detects that the boiler water temperature exceeds the set normal temperature limit te1 (tentatively set to 95℃), it is ready to flush.

[0164] Rinsing process:

[0165] Reverse hot water flushing: Open the cold milk line reverse cleaning valve V08 and the cold milk reverse cleaning drain valve V04 to flush the pipeline with hot water in the reverse direction. When the timer reaches the set time Tr101 (tentatively set to 30s), close V04 and V08.

[0166] Hot water flushing: Open the cold milk circuit forward cleaning valves V10 and V06, flush with hot water, time Tf101 (tentatively set to 30s), close V10 and V06, and stop the hot water output logic;

[0167] Forward steam flushing: Start the steam output logic of steam boiler G3, perform forward steam sterilization, time Tf201 (tentatively set to 30s), close the relevant valves, and stop the steam output logic;

[0168] Reverse steam flushing: Open V08 and V04 for reverse steam sterilization, timer Tr201 (tentatively set to 30s), close V08 and open V06.

[0169] End phase: After the steam output logic stops for 2 seconds, L2 switches to green light flashing 5 times, then the green light stays on; the valve opening time after steam cleaning is set to T072 (tentatively set to 15s), at which time V04 and V06 are closed, the system reports that hot water flushing of cold milk pipe is complete, and the boiler resumes heating and water replenishment.

[0170] (III) Automatic hot water cleaning logic for the milk heating pipe

[0171] See Figure 17 Preparation phase: After receiving the instruction, the L1 red light flashes (cycle 1 second), waits for 3 seconds, starts the boiler normal logic and then switches to hot water output logic. T1 detects that the water temperature exceeds te1 (95℃) and then prepares to flush.

[0172] Rinsing process:

[0173] Reverse hot water flushing: Open the hot milk circuit reverse cleaning valve V07 and the hot milk reverse cleaning drain valve V03, flush with hot water, timer Tr111 (tentatively set to 30s), then close V03 and V07.

[0174] Hot water flushing: Open the hot milk circuit forward cleaning valves V09 and V05, flush with hot water, time Tf111 (tentatively set to 30s), close V09 and V05, and stop the hot water output logic;

[0175] Forward steam flushing: Start the G3 steam output logic, perform forward steam sterilization, time Tf211 (tentatively set to 30s), close the relevant valves, and stop the steam output logic;

[0176] Reverse steam flushing: Open V03 and V07 for reverse steam sterilization, timer Tr211 (tentatively set to 30s), close V07 and open V05.

[0177] End phase: After the steam output logic stops for 2 seconds, L1 switches to green light flashing 5 times, then the green light stays on; timer T071 (tentatively set at 15s), when the time is up, V03 and V05 are shut off, the system reports that the hot water flushing of the hot milk pipe is complete, and the boiler resumes heating and water replenishment.

[0178] VI. Deep Cleaning Logic

[0179] See Figure 18 Through multiple rounds and methods of cleaning (cleaning solution cleaning, hot water rinsing, steam rinsing) combined with milk pump reversal, the pipeline is thoroughly cleaned. The specific process is as follows:

[0180] Parameter preparation: Define the cycle count (CYC), set the cleaning fluid extraction speed (V3, tentatively 70%), pump reverse rotation speed (V4, tentatively 40%), cleaning fluid forward flushing time (Tf31, tentatively 40s), cleaning fluid forward bypass flushing time (Tf32, tentatively 20s), intermediate waiting time (Tw1, tentatively 10min), hot water reverse flushing time (Tr31, tentatively 60s), hot water bypass flushing time (Tr32, tentatively 30s), hot water forward flushing time (Tf33, tentatively 60s), steam reverse flushing time (Tr41, tentatively 60s), steam bypass flushing time (Tr42, tentatively 30s), steam forward flushing time (Tf41, tentatively 60s), boiler normal operating temperature limit (te1, tentatively 95°C), and valve opening time after cleaning (T07, tentatively 20s).

[0181] It should be noted that the "%" in the above parameters refers to the percentage of the pump's rated operating power, that is, the pump operates at 70% of its rated power to control the extraction and delivery flow of the cleaning fluid.

[0182] Startup procedure:

[0183] 1. Initial Stage: Press the deep cleaning button for 3 seconds. The two red lights will flash, and the cycle count record CYC will be set to 0 to prepare for subsequent cycle counting. Preparation before cleaning with cleaning solution: Open the relevant valves to allow the cleaning solution to enter the pipeline. At the same time, start the timer. According to the set cleaning solution forward flushing time Tf31 and forward bypass flushing time Tf32, control the cleaning solution to flow forward and bypass in the hot milk and cold milk pipelines to complete the initial cleaning of the pipeline with the cleaning solution.

[0184] 2. Cleaning, Descaling, and Soaking Stage: Cleaning solution circulation: Different pumps are controlled by valves to draw cleaning solution, allowing it to circulate forward through the hot and cold milk lines to remove scale. Afterward, it enters a forward bypass circulation to expand the cleaning coverage. Soaking Stopped: After cleaning solution circulation is complete, the soaking stage begins. The flow of cleaning solution is paused, and the chemical action of the solution allows the scale to dissolve fully. This stage has no specific order and is a settling process. Repeated Cleaning Solution Circulation: After soaking, the cleaning solution is circulated again in both the forward and forward bypass paths of the hot and cold milk lines to enhance the descaling effect. The process is the same as before.

[0185] 3. Flushing Phase (Hot Water Flushing) Reverse Hot Water Flushing (Hot Milk Line): Open the relevant hot water valves and allow hot water to flow in the reverse direction in the hot milk line for a time of Tr31, flushing away residual cleaning solution and dissolved dirt; then perform reverse bypass flushing for Tr32. Forward Hot Water Flushing (Hot Milk Line): Switch the valves to allow hot water to flow in the forward direction in the hot milk line for a time of Tf33, further cleaning the line. Cold Milk Line Hot Water Flushing: Repeat the above reverse, reverse bypass, and forward hot water flushing process to clean the cold milk line, using the same parameters as the hot milk line hot water flushing.

[0186] 4. Disinfection Stage: The cleaning solution is circulated again in the forward and forward bypass loops of the hot and cold milk pipelines. The disinfecting effect of the cleaning solution is used to disinfect the pipelines, following the same process as the cleaning and descaling stage. Soaking Stop: After the cleaning solution circulation disinfection, the pipeline enters a soaking and settling stage. A waiting time can be set to enhance the disinfection effect. Repeat Cleaning Solution Circulation Disinfection: After soaking, the cleaning solution is circulated again in the forward and forward bypass loops of the hot and cold milk pipelines for disinfection.

[0187] 5. Rinsing / Sterilization Stage (Steam Rinsing) Reverse Steam Rinsing (Hot Milk Line): Open the relevant steam valves and allow steam to flow in reverse through the hot milk line for a reverse rinsing time Tr41, using high-temperature steam to kill residual microorganisms; then perform reverse bypass rinsing for Tr42. Forward Steam Rinsing (Hot Milk Line): Switch the valves to allow steam to flow forward through the hot milk line for a rinsing time Tf41, enhancing sterilization and cleaning effects. Cold Milk Line Steam Rinsing: Repeat the above reverse, reverse bypass, and forward steam rinsing process to treat the cold milk line, using the same parameters as the hot milk line steam rinsing.

[0188] 6. End of Cleaning and Fluid Replacement & Cycle Count: After completing one deep cleaning cycle, perform a fluid replacement operation and increment the cycle count (CYC) by 1. If multiple cleaning cycles are required, repeat all the above stages; otherwise, proceed to the end stage. End Operation: According to the set valve opening time TO7 after cleaning, open the relevant valves to drain the residual liquid, completing the entire deep cleaning process.
