Description

Technical Field

[0001] This invention relates to the field of coffee machine technology, and more specifically to a milk frother with adaptive temperature control. Background Technology

[0002] Generally, the milk foaming process requires constant temperature preheating of fresh milk, gas-liquid mixing and frothing, and precise temperature control of milk foam output to ensure the fineness, uniformity, and stability of the milk foam. At the same time, after the operation is completed, the residual milk stains in the pipeline must be effectively cleaned to prevent bacteria from growing in the pipeline and affecting the subsequent foaming quality.

[0003] In actual operation, traditional water bath preheating structures generally suffer from turbulent hot and cold water convection. The heated hot water diffuses irregularly, and hot and cold water are mixed in layers, resulting in uneven heat exchange of fresh milk and large fluctuations in preheating temperature. When the fresh milk enters the frothing structure for gas-liquid mixing and frothing, the unstable temperature of the fresh milk directly leads to uneven foam size and poor fluffiness, making it impossible to form standard foam. Moreover, during continuous frothing operation, the water in the storage tank continuously loses heat, and the water temperature gradually decreases, resulting in insufficient heat exchange time and inadequate preheating of the fresh milk. At the same time, the concentrated water flow during water replenishment in conventional equipment can easily cause a sudden drop in local water temperature and uneven water mixing, further disrupting the heat exchange environment and reducing preheating stability. In addition, after long-term operation, a large amount of milk stains and dirt will remain on the pump body and pipelines. Based on this, the present invention aims to provide a milk frothing machine with temperature adaptive control that can stabilize the heat exchange temperature of fresh milk, achieve temperature adaptive regulation, and improve frothing accuracy and operational continuity. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a milk frothing machine with adaptive temperature control, thereby solving the technical problems in the prior art.

[0005] The objective of this invention can be achieved through the following technical solutions: A milk frothing machine with adaptive temperature control, comprising: The machine body has a nozzle fixedly installed on it. A mixing pump, a whipping pump, a delivery pipe, a water storage tank, and a heating base are fixedly installed inside the machine body. A heating element is installed inside the machine body. The mixing pump is connected to the nozzle sequentially through the whipping pump, the heating element, and the delivery pipe. The mixing pump is connected to the water storage tank through a cleaning pipe. The water storage tank is fixedly installed on the heating base, and a heating coil is fixedly installed on the heating base. The heating coil is used to heat the water in the water storage tank. An input pipe and an output pipe are fixedly installed through the outer circumference of the water storage tank. The horizontal height of the input pipe is higher than that of the output pipe, and the two are connected through a spiral tube. The spiral tube is located in the water in the water storage tank and is directly above the heating coil. The input pipe is used to deliver fresh milk. The mixing pump is connected to a water inlet pipe, an air inlet pipe, a milk inlet pipe, and a cleaning pipe. The mixing pump is connected to the output pipe through the milk inlet pipe.

[0006] As a further aspect of the present invention: an outer spiral baffle and an inner spiral baffle are fixedly installed inside the water storage cylinder, and the spiral tube is located between the outer spiral baffle and the inner spiral baffle. The surfaces of the outer spiral baffle and the inner spiral baffle are arranged at an angle. The distance between the surface of the outer spiral baffle and the spiral tube increases downward in the vertical direction, and the distance between the surface of the inner spiral baffle and the spiral tube also increases downward in the vertical direction.

[0007] As a further aspect of the present invention: a temperature sensor and a throttle valve are fixedly installed on the output pipe. The temperature sensor is used to monitor the temperature of the fresh milk flowing through the output pipe. When the temperature of the fresh milk is lower than the threshold, the temperature sensor controls the opening of the throttle valve to decrease.

[0008] As a further aspect of the present invention: the mixing pump is connected to the water storage tank through a cleaning pipe, and a water supply pipe is connected to the top of the water storage tank. A turbine is rotatably installed inside the water supply pipe. When water enters the water supply pipe, the water flow drives the turbine to rotate.

[0009] As a further embodiment of the present invention: a stirring rod is rotatably mounted on the bottom plate of the water storage tank, and the turbine is coaxially and fixedly connected to the top end of the stirring rod.

[0010] As a further aspect of the present invention: an electric cylinder is fixedly installed at the top of the water storage cylinder, and a water immersion block is fixedly installed at the movable end of the electric cylinder. The water immersion block is located above the liquid surface. A liquid level monitoring component is provided inside the water storage cylinder. When the liquid level in the water storage cylinder drops, the electric cylinder drives the water immersion block to descend and immerse itself in the water, thereby causing the liquid level to rise.

[0011] As a further embodiment of the present invention: the liquid level monitoring component includes a float, a lifting rod, and a feedback component. The lifting rod is slidably installed on the top of the water storage tank, and the float is fixedly installed on the bottom of the lifting rod, floating on the liquid surface inside the water storage tank. The feedback component includes a fixed plate, a descent switch, and an ascent switch. The fixed plate is fixedly installed on the top of the water storage tank, and both the descent switch and the ascent switch are fixedly installed on the fixed plate, with the descent switch located above the ascent switch. Both the descent switch and the ascent switch are connected to an electric cylinder. When the lifting rod descends, the descent switch drives the immersion block to descend via the electric cylinder. When the lifting rod rises, the ascent switch drives the immersion block to rise via the electric cylinder.

[0012] As a further embodiment of the present invention: the feedback component further includes a rotating rod and a vertical rod, the vertical rod is fixedly installed on the top of the water storage tank, the vertical rod is located between the fixed plate and the lifting rod, the rotating rod is rotatably installed on the top of the vertical rod, one end of the rotating rod is located between the lowering switch and the raising switch, and the other end of the rotating rod is rotatably connected to the top of the lifting rod.

[0013] The beneficial effects of this invention are: 1. In this invention, by setting an outer spiral baffle and an inner spiral baffle inside the water storage tank to form a closed heat exchange zone, and in conjunction with the spiral tube directional heat exchange structure above the heating coil, the heated high-temperature hot water is confined and gathered on the outer periphery of the spiral tube, and the cooled water slides away from the heat exchange area along the inclined plate surface, achieving precise stratification and isolation of hot and cold water. At the same time, relying on the linkage control structure of temperature sensor and throttling valve, the medium flow rate can be adaptively adjusted according to the real-time temperature of fresh milk, dynamically compensating for the heat exchange deficiency caused by water temperature loss, greatly improving the uniformity and temperature stability of fresh milk preheating, and improving the defects of uneven milk foam size, poor fluffiness, and unstable forming quality.

[0014] 2. In this invention, the coaxial linkage structure between the turbine inside the water supply pipe and the stirring rod at the bottom of the water storage tank utilizes the power of the water flow to synchronously achieve water flow dispersion and water mixing. This transforms the traditional centralized direct flushing water supply into uniform water spray water supply, and quickly integrates new and old water, eliminating local temperature differences and water stratification within the tank. It maintains a constant water temperature inside the storage tank without the need for additional power components. At the same time, an independent cleaning pipe directly draws high-temperature hot water from the tank to instantly flush the milk circuit and pump body, eliminating the need to wait for the water to cool down. This completely solves the problems of delayed cleaning, milk residue breeding bacteria, and poor operational continuity in traditional equipment, effectively improving the equipment's self-cleaning ability and long-term operational stability.

[0015] 3. In this invention, a lever-type liquid level feedback structure is formed by a float, a lifting rod, a vertical rod, and a rotating rod. The linkage between the electric cylinder and the immersion block realizes automatic liquid level compensation and reset. When the liquid level drops due to pumping water for cleaning the equipment and the spiral tube is exposed and at risk of overheating, the liquid level can be quickly raised by squeezing the volume of the immersion block. The spiral tube is kept completely submerged in the water bath environment throughout the process, eliminating the problems of exposed heat exchange pipes, preheating failure, and temperature runaway.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-8 As shown, the present invention is a milk frothing machine with adaptive temperature control, comprising: A machine body 1 is provided, on which a nozzle 3 is fixedly installed. Inside the machine body 1 are a mixing pump 4, a whittling pump 5, a delivery pipe 7, a water storage tank 8, and a heating base 9. A heating element 6 is also provided inside the machine body 1. The mixing pump 4 is connected to the nozzle 3 sequentially through the whittling pump 5, the heating element 6, and the delivery pipe 7. The mixing pump 4 is connected to the water storage tank 8 through a cleaning pipe 404. The water storage tank 8 is fixedly installed on the heating base 9, and a heating coil 901 is fixedly installed on the heating base 9. The heating coil 901 is used to heat the water in the water storage tank 8. An input pipe 1001 and an output pipe 1002 are fixedly installed through the outer circular surface of the water storage cylinder 8. The horizontal height of the input pipe 1001 is higher than that of the output pipe 1002, and the two are connected by a spiral pipe 10. The spiral pipe 10 is located in the water inside the water storage cylinder 8 and is located directly above the heating coil 901. The input pipe 1001 is used to transport fresh milk. The mixing pump 4 is connected to a water inlet pipe 401, an air inlet pipe 402, a milk inlet pipe 403, and a cleaning pipe 404. The mixing pump 4 is connected to the output pipe 1002 through the milk inlet pipe 403.

[0021] The machine body 1 is fixedly equipped with an operation panel 2. The input pipe 1001 is connected to a third three-way valve 13, and the milk inlet pipe 403 is connected to a fourth three-way valve 14. The third three-way valve 13 is connected to the fourth three-way valve 14 through a second branch pipe 15. The heating component 6 includes a heating block 601, a first three-way valve 602, a second three-way valve 603, and a first branch pipe 604. The heating block 601 is disposed inside the machine body 1. The heating block 601 is connected to the frothing pump 5 through the first three-way valve 602. The heating block 601 is connected to the delivery pipe 7 through the second three-way valve 603. The first three-way valve 602 is connected to the second three-way valve 603 through the first branch pipe 604.

[0022] The working principle of this invention is as follows: First, clean water is injected into the water storage tank 8. Then, the heating coil 901 on the heating base 9 is activated to heat the water inside the water storage tank 8. The annular heating coil 901 can evenly heat the water above. The density of the heated water decreases and it floats upward, forming a stable upward flow of hot water inside the water storage tank 8. The spiral tube 10 is precisely arranged on the core path of the rising hot water to maximize the absorption of heat from the water. Fresh milk is introduced through the input pipe 1001. When it flows through the spiral tube 10, it fully exchanges heat with the high-temperature hot water in the water storage tank 8 to complete uniform preheating. The preheated fresh milk is then transported to the mixing pump 4 through the output pipe 1002 and the milk inlet pipe 403. The mixing pump 4 simultaneously draws clean water through the water inlet pipe 401 and draws air through the air inlet pipe 402. The clean water, air, and preheated fresh milk are mixed and then transported to the whipping pump 5 at high speed. The milk is stirred and whipped to form fine and uniform foam. When the foam is delivered to the heating element 6, the operating mode can be switched through the first three-way valve 602 and the second three-way valve 603 in conjunction with the first branch pipe 604. It can be selected to be heated at a constant temperature twice by the heating block 601 or directly delivered through the first branch pipe 604 to adapt to different foaming requirements. Finally, the foam is stably sprayed out from the nozzle 3 through the delivery pipe 7. At the same time, the cold water after heat exchange settles to the sides and bottom of the water storage tank 8, avoiding the heat exchange area of ​​the spiral tube 10. The cold water at the bottom is continuously heated by the heating coil 901 and floats to the surface, forming a closed-loop hot and cold convection circulation to continuously ensure the preheating efficiency and temperature stability of fresh milk. The equipment can switch the pipeline through the third three-way valve 13 and the fourth three-way valve 14 in conjunction with the second branch pipe 15. At the same time, hot water can be drawn through the cleaning pipe 404 to complete the self-cleaning of the pipeline.

[0023] like Figures 1-8 As shown, in a preferred embodiment of the present invention, an outer spiral baffle 16 and an inner spiral baffle 17 are fixedly installed inside the water storage cylinder 8. The spiral tube 10 is located between the outer spiral baffle 16 and the inner spiral baffle 17. The surfaces of the outer spiral baffle 16 and the inner spiral baffle 17 are arranged at an angle. The distance between the surface of the outer spiral baffle 16 and the spiral tube 10 increases downward in the vertical direction, and the distance between the surface of the inner spiral baffle 17 and the spiral tube 10 increases downward in the vertical direction.

[0024] In practical application, this embodiment forms an annular limiting heat exchange zone through the outer spiral baffle 16 and the inner spiral baffle 17. The floating hot water generated by the heating coil 901 is limited and gathered on the outer periphery of the spiral tube 10 by the double-layer baffle, preventing the hot water from spreading and escaping over a large area. This keeps the spiral tube 10 in a state of being surrounded by high-temperature hot water throughout, greatly improving the heat exchange efficiency of the fresh milk. After the hot water completes the heat exchange with the fresh milk in the spiral tube 10, the temperature decreases, and cold water settles. During the falling process, the cold water slides smoothly along the inclined plates of the outer spiral baffle 16 and the inner spiral baffle 17. Relying on the structural characteristics of the plates being wider at the bottom and narrower at the top, the settled cold water gradually moves away from the core heat exchange area of ​​the spiral tube 10, realizing the separation of hot and cold water layers, preventing cold water from interfering with the heat exchange operation, and continuously stabilizing the preheating temperature.

[0025] like Figures 1-4 As shown, in a preferred embodiment of the present invention, a temperature sensor 11 and a throttle valve 12 are fixedly installed on the output pipe 1002. The temperature sensor 11 is used to monitor the temperature of the fresh milk flowing through the output pipe 1002. When the temperature of the fresh milk is lower than the threshold, the temperature sensor 11 controls the opening of the throttle valve 12 to decrease.

[0026] In practical application, the temperature sensor 11 collects the real-time temperature of the fresh milk flowing out of the output pipe 1002. When the monitored fresh milk temperature is lower than the system's preset threshold, it indicates that the current water temperature is insufficient and the heat exchange is inadequate. The temperature sensor 11 immediately controls the throttle valve 12 to operate, reducing the flow opening of the throttle valve 12. After the opening is reduced, the flow velocity of the fresh milk in the input pipe 1001, spiral pipe 10, and output pipe 1002 decreases, prolonging the residence time of the fresh milk in the heat exchange area of ​​the spiral pipe 10. This allows the fresh milk to fully absorb the residual heat of the water, making up for the heat exchange loss caused by the drop in water temperature, and ensuring that the preheating temperature of the fresh milk always meets the standard. When the water temperature rises and the fresh milk temperature meets the standard, the throttle valve 12 can automatically return to its normal opening, ensuring operational efficiency.

[0027] like Figures 1-6 As shown, in a preferred embodiment of the present invention, the mixing pump 4 is connected to the water storage tank 8 through the cleaning pipe 404. The top of the water storage tank 8 is connected to the water supply pipe 18. A turbine 20 is rotatably installed inside the water supply pipe 18. When water enters the water supply pipe 18, the water flow drives the turbine 20 to rotate.

[0028] In practical application, after the equipment completes the foaming operation, the mixing pump 4 can directly draw high-temperature hot water from the water storage tank 8 through the cleaning pipe 404 to rinse the mixing pump 4, the foaming pump 5, and the entire milk pipeline at high temperature, quickly dissolving residual milk stains and grease without waiting for the water temperature to cool down, thus achieving immediate cleaning of the equipment and greatly improving the continuity of operation. After the water consumption during the cleaning operation causes the liquid level in the water storage tank 8 to drop, the external water source automatically replenishes water through the water replenishment pipe 18. The high-pressure water replenishment flow impacts and drives the turbine 20 to rotate at high speed. The rotating turbine 20 disperses the columnar concentrated water flow into water droplets and sprinkles them evenly, avoiding the concentrated water flow directly hitting the bottom of the tank and causing a sudden drop in local water temperature.

[0029] like Figures 1-6 As shown, in a preferred embodiment of the present invention, a stirring rod 19 is rotatably mounted on the bottom plate of the water storage cylinder 8, and the turbine 20 is coaxially and fixedly connected to the top end of the stirring rod 19.

[0030] In practical application, during the water replenishment process of the water replenishment pipe 18, the water flow drives the turbine 20 to rotate continuously. The turbine 20, relying on the coaxial fixed structure, synchronously drives the stirring rod 19 of the bottom plate of the water storage cylinder 8 to rotate at high speed. The rotating stirring rod 19 stirs the entire water body inside the water storage cylinder 8 in all directions, quickly merging the newly added low-temperature water replenishment with the original high-temperature water body, eliminating water stratification and local temperature differences, and making the overall water temperature inside the cylinder tend to be uniform.

[0031] like Figures 5-6 As shown, in a preferred embodiment of the present invention, an electric cylinder 21 is fixedly installed at the top of the water storage cylinder 8, and a water immersion block 22 is fixedly installed at the movable end of the electric cylinder 21. The water immersion block 22 is located above the liquid surface. A liquid level monitoring component is provided inside the water storage cylinder 8. When the liquid level in the water storage cylinder 8 drops, the electric cylinder 21 drives the water immersion block 22 to descend and immerse itself in the water, thereby causing the liquid level to rise.

[0032] In practical application, the liquid level monitoring component monitors the liquid level inside the water storage tank 8 in real time. When the equipment draws hot water to clean the milk foam pipeline and the liquid level drops to the critical threshold, the monitoring component triggers the electric cylinder 21 to start. The moving end of the electric cylinder 21 extends downward, driving the immersion block 22 to move down from above the liquid surface and completely immerse itself in the water. Relying on the physical volume of the immersion block 22 to occupy the water space, the liquid level is quickly raised without changing the total water volume in the water storage tank 8, ensuring that the liquid surface completely covers the entire structure of the spiral tube 10, eliminating the problem of heat exchange pipeline exposure and heat loss, and continuously ensuring the stable operation of heat exchange.

[0033] like Figures 5-8As shown in the preferred embodiment of the present invention, the liquid level monitoring component includes a float 23, a lifting rod 24, and a feedback component. The lifting rod 24 is slidably installed on the top of the water storage tank 8, and the float 23 is fixedly installed on the bottom of the lifting rod 24, floating on the liquid surface inside the water storage tank 8. The feedback component includes a fixing plate 27, a descent switch 28, and an ascent switch 29. The fixing plate 27 is fixedly installed on the top of the water storage tank 8, and both the descent switch 28 and the ascent switch 29 are fixedly installed on the fixing plate 27. The descent switch 28 is located above the ascent switch 29, and both the descent switch 28 and the ascent switch 29 are connected to an electric cylinder 21. When the lifting rod 24 descends, the descent switch 28 drives the immersion block 22 to descend through the electric cylinder 21. When the lifting rod 24 rises, the ascent switch 29 drives the immersion block 22 to rise through the electric cylinder 21.

[0034] In practical application, the float 23 rises and falls synchronously with the liquid level in the water storage tank 8, causing the lifting rod 24 fixed at the top to slide along the top of the water storage tank 8. When the equipment is pumped for cleaning and the liquid level drops, the float 23 sinks, causing the lifting rod 24 to move down, triggering the descent switch 28. The descent switch 28 outputs an electrical signal to control the electric cylinder 21 to extend, driving the immersion block 22 to immerse itself in water and raise the liquid level. When the water replenishment is completed and the liquid level returns to its original position, the float 23 floats up, causing the lifting rod 24 to move up, triggering the ascent switch 29. The ascent switch 29 controls the electric cylinder 21 to retract, causing the immersion block 22 to move up and detach from the liquid level, preventing the liquid level from overflowing due to excessive height. Through the linkage of the two switches, automatic compensation for low liquid level and automatic reset when the liquid level reaches the standard are achieved. No manual intervention is required throughout the process, and the standard liquid level for heat exchange is accurately maintained.

[0035] like Figures 6-7 As shown, in a preferred embodiment of the present invention, the feedback component further includes a rotating rod 25 and a vertical rod 26. The vertical rod 26 is fixedly installed on the top of the water storage tank 8 and is located between the fixed plate 27 and the lifting rod 24. The rotating rod 25 is rotatably installed on the top of the vertical rod 26. One end of the rotating rod 25 is located between the lowering switch 28 and the raising switch 29, and the other end of the rotating rod 25 is rotatably connected to the top of the lifting rod 24.

[0036] In practical application, the upright 26 provides a rotational support fulcrum for the rotating rod 25, making the rotating rod 25 a lever transmission structure. One end of the rotating rod 25 is hinged to the lifting rod 24, and the other end is suspended between two control switches. When the liquid level in the water tank 8 drops and the lifting rod 24 moves down accordingly, one end of the rotating rod 25 is pulled downward, and the other end of the rotating rod 25 flips upward to abut against the lowering switch 28, quickly triggering the liquid level compensation action. When the liquid level rises and the lifting rod 24 moves up, one end of the rotating rod 25 is pushed upward, and the other end of the rotating rod 25 flips downward to abut against the rising switch 29, quickly triggering the resetting action of the immersion block 22. It should be noted that the water replenishment operation is only performed after the milk foaming operation is completed, so as to avoid the problem of water replenishment and cooling during the preheating process of fresh milk transportation, which would cause fluctuations in the water temperature inside the water tank 8 and a deterioration in the preheating effect.

[0037] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
