Description

Technical Field

[0001] This invention relates to the field of milk frother technology, and more specifically, to a fully automatic milk frother. Background Technology

[0002] Milk frothers typically heat, stir, and inject air into milk, plant-based beverages, or other foamable liquids to create milk foam with a certain volume, fineness, and stability. The air injection stage directly affects the degree of expansion, bubble size, and foam stability of the milk foam.

[0003] Most existing milk frothers use a fixed-duration air injection method, or stop heating only at the end of preparation based on the final temperature. Due to differences in the initial temperature, fat content, protein content, liquid volume, and ambient temperature of different liquids, the actual air injection temperature range may vary under the same injection duration. This can easily lead to problems such as air injection being too early, too late, or lasting too long. When air is injected too early, the liquid temperature is low and the viscosity is high, which may result in large and unevenly distributed bubbles. When air is injected too late or stopped too late, it may cause excessively large foam volume, unstable bubbles, liquid and foam separation, and even a deterioration in the taste of the finished product.

[0004] Therefore, there is an urgent need for a fully automatic milk frother to solve the above problems. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a fully automatic milk frother. This invention automatically controls the air injection process by setting the initial and final air injection temperatures and combining this with real-time temperature data. This ensures that air enters the liquid to be frothed within a suitable temperature range, preventing premature injection or delayed stopping that could result in large, unstable bubbles and a decreased taste. The system can also dynamically adjust and implement anomaly protection based on the temperature change rate, target temperature, maximum injection time, and sensor status, thereby improving the consistency, stability, and control safety of milk froth preparation. It is applicable to different types of liquids and various preparation modes, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic milk frother, comprising a milk frother frame and an air injection temperature control module, wherein side baffles are fixedly installed on both sides of the milk frother frame, a control console is fixedly installed on the top front side of the milk frother frame, a touch panel is fixedly installed on the front side of the control console, a water collection box is fixedly installed on the bottom front side of the milk frother frame, a water filter plate is provided on the top of the water collection box, the shape of the water filter plate matches the shape of the top opening of the water collection box, a high-temperature steam pipe is provided at the bottom of the control console, a cup limiting bracket is provided on the outer side of the bottom of the high-temperature steam pipe, the cup limiting bracket is C-shaped in plan view, the cup limiting bracket is fixedly installed on the bottom front side of the milk frother frame by screws, the cup limiting bracket is located between the control console and the water collection box, four plastic support legs are provided at the bottom of the milk frother frame, and a compressed air storage tank is provided inside the milk frother frame; The air injection temperature control module includes a temperature acquisition module, a control processing module, an air injection control module, a heating status acquisition module, and a parameter storage module. The temperature acquisition module is used to acquire the real-time temperature of the liquid to be foamed; The parameter storage module is used to store the air injection start temperature, the air injection stop temperature, and the preparation target temperature; The heating status acquisition module is used to acquire the heating operation status of the milk frother; The control processing module is communicatively connected to the temperature acquisition module, the air injection control module, the heating status acquisition module, and the parameter storage module. The control processing module is used to compare the real-time temperature with the air injection start temperature and the air injection stop temperature. When the real-time temperature reaches the air injection start temperature and the heating operation status is heating, the control processing module generates an air injection start signal. When the real-time temperature reaches the air injection stop temperature, the control processing module generates an air injection stop signal. The air injection control module is used to start air injection according to the air injection start signal and stop air injection according to the air injection stop signal. The stop air injection temperature is greater than the air injection start temperature and less than or equal to the preparation target temperature.

[0007] In a preferred embodiment, the control processing module is further configured to determine the rate of change of liquid temperature based on real-time temperature, and generate an air injection stop signal in advance or reduce the air injection intensity corresponding to the air injection control module when the rate of change of temperature is greater than a preset heating rate threshold.

[0008] In a preferred embodiment, the parameter storage module stores multiple control parameter groups corresponding to the preparation mode. Each control parameter group includes an air injection start temperature, an air injection stop temperature, a preparation target temperature, and a maximum air injection duration. The control processing module is used to call the corresponding control parameter group according to the selected preparation mode.

[0009] In a preferred embodiment, the preparation mode includes a hot milk foam mode, a low-temperature milk foam mode, a high-foam mode, a fine milk foam mode, a milk mode, and a plant-based beverage mode.

[0010] In a preferred embodiment, the control processing module is further configured to accumulate the air injection duration after the air injection is started. When the air injection duration reaches the preset maximum air injection duration, but the real-time temperature has not reached the stop air injection temperature, the control processing module generates an air injection stop signal.

[0011] In a preferred embodiment, the temperature acquisition module includes two temperature detection channels, and the control processing module is used to determine the consistency of the temperature data acquired by the two temperature detection channels. When the temperature deviation between any temperature detection channel and the other temperature detection channel is greater than a preset deviation threshold, the corresponding temperature detection channel is determined to be an abnormal channel, and air injection is controlled based on the temperature data of the channels not determined to be abnormal.

[0012] In a preferred embodiment, the control processing module is further configured to generate an air injection stop signal and record the corresponding abnormal state when the real-time temperature is detected to be higher than the preparation target temperature, the temperature acquisition module outputs invalid temperature data, the heating state is abnormal, or the air injection duration exceeds the safe duration.

[0013] In a preferred embodiment, the control processing module keeps the air injection control module in a closed state before the real-time temperature reaches the air injection start temperature, and keeps the air injection control module in an open state or an intermittent open state when the real-time temperature is between the air injection start temperature and the air injection stop temperature.

[0014] In a preferred embodiment, the control processing module is further configured to continue monitoring the real-time temperature after the air injection is stopped, maintain heating control when the real-time temperature has not reached the preparation target temperature, and generate a preparation end signal when the real-time temperature reaches the preparation target temperature.

Furthermore, the invention can correct the air injection process based on the rate of temperature change, target temperature, and sensor status. It can stop or limit air injection when overheating, temperature sensor malfunction, or abnormal temperature changes are detected, thereby reducing the risks of over-frothing, foam coarsening, and abnormal operation. The system parameters are adaptable to different types of emulsions and milk foam preparation modes, enhancing the automation control capabilities and applicability of the milk frother.

[0023] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5As shown, the present invention provides a fully automatic milk frother, including a milk frother frame 1 and an air injection temperature control module.

A touch panel 4 is fixedly installed on the front side of the control panel 3. A water collection box 5 is fixedly installed on the bottom front side of the milk frother frame 1. A filter plate 6 is provided on the top of the water collection box 5, and the shape of the filter plate 6 matches the shape of the top opening of the water collection box 5. A high-temperature steam pipe 7 is provided at the bottom of the control panel 3. A cup limiting bracket 8 is provided on the outer side of the bottom of the high-temperature steam pipe 7. The cup limiting bracket 8 has a C-shaped shape when viewed from above. The cup limiting bracket 8 is fixedly installed on the bottom front side of the milk frother frame 1 by screws. The cup limiting bracket 8 is located between the control panel 3 and the water collection box 5. Four plastic support legs 9 are provided at the bottom of the milk frother frame 1. A compressed air storage tank 10 is provided inside the milk frother frame 1. The air injection temperature control module includes a temperature acquisition module, a control processing module, an air injection control module, a heating status acquisition module, and a parameter storage module. The temperature acquisition module is used to acquire the real-time temperature of the liquid to be foamed; The parameter storage module is used to store the air injection start temperature, the air injection stop temperature, and the preparation target temperature; The heating status acquisition module is used to acquire the heating operation status of the milk frother; The control processing module is communicatively connected to the temperature acquisition module, the air injection control module, the heating status acquisition module, and the parameter storage module. The control processing module is used to compare the real-time temperature with the air injection start temperature and the air injection stop temperature. When the real-time temperature reaches the air injection start temperature and the heating operation status is heating, the control processing module generates an air injection start signal. When the real-time temperature reaches the air injection stop temperature, the control processing module generates an air injection stop signal. The air injection control module is used to start air injection according to the air injection start signal and stop air injection according to the air injection stop signal. The stop air injection temperature is greater than the air injection start temperature and less than or equal to the preparation target temperature.

[0024] The control processing module is also used to determine the rate of change of liquid temperature based on real-time temperature, and to generate an air injection stop signal in advance or reduce the air injection intensity corresponding to the air injection control module when the rate of change of temperature is greater than the preset heating rate threshold.

[0025] The parameter storage module stores multiple control parameter groups corresponding to the preparation modes. Each control parameter group includes the air injection start temperature, the air injection stop temperature, the preparation target temperature, and the maximum air injection duration. The control processing module is used to call the corresponding control parameter group according to the selected preparation mode.

[0026] The preparation modes include hot milk foam mode, low-temperature milk foam mode, high foam mode, fine milk foam mode, milk mode, and plant-based beverage mode.

[0027] The control processing module is also used to accumulate the air injection time after the air injection is started. When the air injection time reaches the preset maximum air injection time, but the real-time temperature has not reached the stop air injection temperature, the control processing module generates an air injection stop signal.

[0028] The temperature acquisition module includes two temperature detection channels. The control and processing module is used to judge the consistency of the temperature data acquired by the two temperature detection channels. When the temperature deviation between any temperature detection channel and the other temperature detection channel is greater than a preset deviation threshold, the corresponding temperature detection channel is judged as an abnormal channel, and air injection is controlled based on the temperature data of the channels that are not judged as abnormal channels.

[0029] The control processing module is also used to generate an air injection stop signal and record the corresponding abnormal state when the real-time temperature is detected to be higher than the preparation target temperature, the temperature acquisition module outputs invalid temperature data, the heating state is abnormal, or the air injection duration exceeds the safe duration.

[0030] The control processing module keeps the air injection control module in a closed state before the real-time temperature reaches the air injection start temperature, and keeps the air injection control module in an open state or intermittently open state when the real-time temperature is between the air injection start temperature and the air injection stop temperature.

[0031] The control processing module is also used to continue monitoring the real-time temperature after the air injection is stopped, maintain heating control when the real-time temperature has not reached the preparation target temperature, and generate a preparation end signal when the real-time temperature reaches the preparation target temperature.

[0032] The specific implementation method is as follows: When using this invention, firstly, the preparation mode selected by the user is obtained, and the air injection start temperature, stop air injection temperature, and preparation target temperature corresponding to the preparation mode are called. The real-time temperature of the liquid to be foamed and the heating operation status of the milk frother are collected. When the real-time temperature reaches the air injection start temperature and the milk frother is in the heating state, an air injection start signal is output. During the air injection process, the real-time temperature is continuously collected and compared with the stop air injection temperature. When an abnormal temperature collection is detected, the real-time temperature exceeds the preparation target temperature, the air injection time exceeds the maximum air injection time, or the temperature change rate exceeds a preset threshold, the system will take action. The system outputs an air injection stop signal in advance. When the real-time temperature reaches the stop air injection temperature, it outputs another stop air injection signal. After stopping air injection, it continuously monitors the real-time temperature and outputs a preparation end signal when the real-time temperature reaches the target preparation temperature. It also outputs an air injection stop signal in advance when abnormal temperature acquisition, real-time temperature exceeding the target preparation temperature, air injection duration exceeding the maximum air injection duration, or temperature change rate exceeding a preset threshold is detected. This invention controls the air injection state based on the real-time liquid temperature collected during the preparation process by setting the air injection start temperature and stop air injection temperature, ensuring air is injected into the liquid within a suitable temperature range. This system reduces air injection deviations caused by differences in initial liquid temperature, liquid volume, and ambient temperature, improving the consistency of milk foam volume, fineness, and stability. Furthermore, this invention can correct the air injection process based on the temperature change rate, target temperature, and sensor status, and stop or limit air injection when overheating, temperature sensor malfunction, or abnormal temperature changes are detected, thereby reducing the risk of over-frothing, foam coarsening, and abnormal operation. The system parameters are adaptable to different types of emulsions and different milk foam preparation modes, improving the automation control capability and applicability of the milk frother.

[0033] Working principle of this invention: Refer to the instruction manual appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5When using this invention, an air injection temperature control module is included. This allows the invention to control the air injection state by setting the initial and stopping air injection temperatures, based on the real-time liquid temperature collected during the preparation process, ensuring that air is injected into the liquid within a suitable temperature range. This system reduces injection deviations caused by differences in initial liquid temperature, liquid volume, and ambient temperature, improving the consistency of milk foam volume, fineness, and stability. Furthermore, this invention can correct the air injection process based on the rate of temperature change, target temperature, and sensor status, and stop or limit air injection when overheating, temperature sensor malfunction, or abnormal temperature changes are detected, thereby reducing the risk of over-frothing, foam coarsening, and abnormal operation. The system parameters are adaptable to different types of emulsions and different milk foam preparation modes, improving the automation control capabilities and applicability of the milk frother.
