Description

Technical Field

[0001] The present invention relates to the technical field of food or beverage preparation, and in particular to an emulsifying device and a beverage machine. Background Art

[0002] As people's living standards improve, beverage machines are becoming increasingly popular. For example, coffee machines, which can quickly and conveniently provide coffee, have become a staple in offices, entertainment venues, and even homes. With the rapid development of fully automatic coffee machines, their functionality is also becoming increasingly powerful. Currently, fully automatic coffee machines on the market generally include an emulsifier for making milk coffee. This emulsifier mixes air, steam, and milk in a mixing chamber through separate pipes in a specific proportion to form milk froth. The milk froth is then mixed with the coffee to create the milk coffee served to the user.

[0003] Emulsifying equipment is typically equipped with a Venturi device, which mixes the drawn-in milk with steam to create hot milk or milk froth. During use, milk, air, and steam are mixed and ejected into a mixing chamber to form milk froth, or simply milk and steam are mixed to create hot milk. Whether using cold or room-temperature milk to make hot milk / milk froth, the same amount of milk is drawn in. This ultimately results in the finished hot milk / milk coffee not reaching the standard temperature. Furthermore, the temperatures of hot milk and milk froth produced by the same device within the same coffee machine can vary, as different inlet milk temperatures result in different outlet milk temperatures.

[0004] Due to structural and cost limitations, when a beverage machine uses a Venturi device to heat milk or froth milk, the steam temperature and flow rate are fixed or can only be varied within a small range. When the same Venturi device draws in milk of different temperatures, the temperature of the hot milk (hot milk froth) produced by the device varies, affecting the taste and quality of the latte. For example, when using milk at different temperatures, the temperature of the hot milk / hot milk froth produced also varies. It can be seen that different temperatures of the drawn milk affect the final temperature of the hot milk / hot milk froth.

[0005] In addition, the temperature sensor used to detect the temperature of the milk is set at the milk tank. Each time it is used, the temperature sensor needs to be placed in the milk and the milk tube needs to be inserted. It is inconvenient to use. When cleaning, the temperature sensor needs to be unplugged from the machine and cleaned manually, which has certain operating requirements for the operator.

[0006] Therefore, it is necessary to further improve the existing technology. Summary of the Invention

For example, a user standing in front of the beverage dispenser to dispense a beverage.

[0042] As used herein, the terms "first," "second," and "third" may be used interchangeably to distinguish one component from another, and these terms are not intended to indicate the position or importance of the various components. The terms "upstream" and "downstream" refer to the relative directions relative to the flow of fluid in a fluid pathway. For example, "upstream" refers to the direction from which the fluid is flowing, while "downstream" refers to the direction to which the fluid is flowing. In addition, approximate terms, such as "substantially" or "approximately" include values ​​that are within ten percent greater or less than the stated value. When used in the context of an angle or direction, such terms include directions that are within ten degrees greater or less than the stated angle or direction. For example, "vertical" or "horizontal" include directions that are within ten degrees of a vertical line or a horizontal line in either direction (e.g., clockwise or counterclockwise).

[0043] The emulsifying device in the specific embodiment of the present invention is described by taking the milk foamer used in the beverage machine as an example. Figures 1 to 5 As shown, in this embodiment, the emulsifying device 100 is connected to a steam source for producing a target liquid. The steam source can be a steam source on a beverage dispenser, an independent steam source, or a steam source dedicated to a milk frother. The target liquid can be hot milk or milk foam. The emulsifying device 100 includes a main body 21 defining a mixing chamber 211. The main body is provided with a milk inlet channel 212, an air channel 213, a steam channel 214, and a liquid outlet 215. The milk inlet channel 212, the air channel 213, the steam channel 214, and the liquid outlet 215 are all in communication with the mixing chamber. The milk inlet channel 212 has a liquid inlet 216. The main body 21 can be a Venturi device, and the steam channel 213 is connected to the steam source of the beverage machine. Due to the Venturi effect, when the steam flows into the mixing chamber 211, a negative pressure is formed at the outlet end of the channel, so that the milk is sucked into the mixing chamber 211 through the liquid inlet 216 of the milk inlet channel 213. After the milk and steam and / or air are mixed in the mixing chamber 211, hot milk or milk foam is discharged from the liquid outlet 215.

[0044] The emulsifying device 100 also includes a delivery assembly 30, which selectively communicates with the mixing chamber 211 and defines at least a portion of a liquid flow path for delivering the source liquid from the container to the mixing chamber 211. The at least portion of the liquid flow path defined by the delivery assembly 30 may be the entire liquid flow path from the container to the mixing chamber 211, or may be a portion of the liquid flow path between a conduit extending into the container and the mixing chamber 211. The container may be any milk container external to the emulsifying device 100, such as a milk box or milk can. The milk container may be placed adjacent to the emulsifying device 100 or in a refrigerated storage device adjacent to the emulsifying device 100. The delivery assembly 30 may draw the source liquid from the refrigerated storage device or remove the milk container from the refrigerated storage device as needed. Alternatively, the container may be connected to or integral to the emulsifying device 100, allowing the user to add milk as needed. The milk or other liquid stored in the container is considered the source liquid.

[0045] The emulsifying device 100 further includes a temperature sensor 40 and a controller. The temperature sensor 40 is used to detect the temperature of the source liquid to be delivered to the mixing chamber 211. The temperature sensor 40 is connected to the controller, which responds to the output of the temperature sensor 40. The controller can respond to the output of the temperature sensor 40 by controlling the flow of milk entering the mixing chamber 211, the temperature and / or flow of the steam, and so on, thereby ensuring that the resulting hot milk or milk foam meets user requirements, such as the temperature and taste expected of a typical milk coffee, thereby satisfying user needs. In this embodiment, the temperature sensor 40 is preferably an NTC (thermistor) due to its high sensitivity, small size, and simple structure, making it easy to install on the emulsifying device.

[0046] The conveying assembly 30 includes a first connector 31, which is detachably connected to a temperature sensor 40. The temperature sensor 40 includes a detection probe 41. The detection probe 41 is located within at least a portion of the liquid flow path defined by the conveying assembly 30. This allows the source liquid flowing through the at least portion of the liquid flow path to contact the detection probe 41, thereby detecting the temperature of the source liquid. The first connector 31 can be connected between a conduit extending into the container and the liquid inlet 216. Another conduit section can also be provided between the liquid inlet 216 and the first connector 31, with the two conduit sections connected to the upstream and downstream ends of the first connector, respectively. Alternatively, one end of the conduit can extend into the container containing milk, while the other end is connected to the liquid inlet of the mixing chamber, with the first connector connected between the two ends of the conduit. The number of conduits is not limited, as long as they can be connected to the first connector 31 and the detection probe 41 can extend into the liquid flow path of the conveying assembly 30.

[0047] By providing a joint in the liquid flow path from the container to the mixing chamber 211 so as to be detachably connected to the detection probe 41 of the temperature sensor 40, it is no longer necessary to place the temperature sensor 40 in the milk container for temperature measurement in advance. The detection probe 41 is detachably connected via the first joint 31, and disassembly is convenient. The detection probe 41 can be exposed by removing the first joint 31, and the detection probe 41 is very easy to clean. In addition, the milk temperature can be detected in real time to ensure the optimal temperature of the milk.

[0048] In this embodiment, the emulsifying device 100 includes a housing 50, within which the main body 21 of the emulsifying device 100 is housed. The detection probe 41 extends outward from the housing 50. The detection probe 41 is exposed from the housing 50, making it convenient to connect and disconnect the first connector 31 from the detection probe 41 and facilitating cleaning of the detection probe 41. Furthermore, positioning the detection probe 41 within the housing 50 facilitates securing the main body of the temperature sensor 40 within the housing 50 and connecting circuits, thereby enhancing user reliability.

[0049] Of course, in other feasible solutions, the detection probe 41 can also be hidden in a groove or cavity on the housing to prevent accidental contact and damage to the detection probe. Because there is space outside the detection probe, the first connector 31 can be inserted through the opening of the groove or cavity to connect with the detection probe. Moreover, a cleaning tool can also be used to clean the detection probe through the opening of the groove or cavity. Alternatively, the detection probe 41 can be movably connected to the housing, allowing the detection probe 41 to be exposed or hidden when needed. These methods all allow the first connector 31 to be detachably connected to the temperature sensor 40. The detection probe 41 is located in the liquid flow path, which can not only detect the milk temperature in real time, but also facilitate cleaning of the detection probe.

[0050] In this embodiment, the detection probe 41 is connected to the housing 50 and to the controller via a wire. The temperature sensor 40 is mounted on the housing 50 of the emulsifying device, meaning that the temperature sensor 40 is placed within the device rather than inserted into the container. Therefore, it does not need to be placed in the milk for temperature measurement. Connecting the detection probe 41 via the first connector 31 facilitates cleaning and removal, and allows for real-time milk temperature monitoring to ensure optimal milk delivery temperature. Furthermore, the detection probe 41 is preferably fixed to the housing 50, meaning that the temperature sensor 40 is non-detachable, thus ensuring its longevity. Removing the first connector 31 allows for easy access to the temperature sensor, making cleaning easier and reducing operational complexity.

[0051] Furthermore, the delivery assembly 30 also includes a second connector 32 connected to the first connector 31. The second connector 32 is connected to the liquid inlet 216 of the mixing chamber 211, and the detection probe 41 is located on the liquid flow path upstream of the second connector 32. That is, the first connector 31 and the second connector 32 can be arranged sequentially along the flow path of the source liquid from the container to the mixing chamber 211. The two connectors can be independent of each other, with the first connector 31 being detachably connected to the detection probe 41, and the second connector 32 being detachably connected to the liquid inlet 216 of the mixing chamber. The independent disassembly of each connector can provide the user with more options and can be replaced independently when needed. The two connectors can be connected via a conduit or other means.

[0052] In this embodiment, the first connector 31 and the second connector 32 are preferably integrally formed. The integral formation includes the two connectors being integrally formed, and the two connectors being individually integrally formed and then connected together. The two integrally formed connectors have better sealing properties and can simultaneously connect the detection probe 41 and the liquid inlet 216 of the mixing chamber 211, making them reliable to use and more convenient and quick to operate. The first connector 31 and the second connector 32 are integrally formed, easy to install, and can be disassembled and cleaned as a whole. The installation of the two connectors only requires plugging and unplugging them into the corresponding positions. When the two connectors are disassembled, the detection probe 41 of the temperature sensor 40 can also be cleaned to ensure the sensitivity of the temperature sensor.

[0053] Reference Figures 6 to 7 The first connector 31 includes a first receptacle 311, which communicates with the liquid flow path of the delivery assembly 30. The detection probe 41 is inserted into the first receptacle 311 to contact the source liquid in the liquid flow path. The first connector 31 can be configured to have a predetermined elasticity. For example, the first connector 31 itself can be constructed of an elastic material, an elastic material can be disposed within the first receptacle 311, or the first connector 31 can include a seal formed of an elastic material. This elastic material can be used to achieve a seal between the first connector 31 and the detection probe 41, thereby improving the seal when the detection probe 41 is inserted into the first receptacle 311.

[0054] In order to facilitate the connection and disassembly of the two connectors, the connection direction of the first connector 31 and the detection probe 41 and the connection direction of the second connector 32 and the liquid inlet 216 are parallel, which is more convenient during connection and disassembly, and the user operation is simpler and more labor-saving. Of course, it can also be set so that the connection direction of the first connector 31 and the detection probe 41 and the connection direction of the second connector 32 and the liquid inlet 216 are at an angle. For example, the two connectors are connected by soft glue or the two connectors themselves are made of soft glue, and can be independently connected to the corresponding detection probe 41 and liquid inlet 216; or the two connectors can be relatively movable so as to achieve simultaneous connection with the corresponding detection probe 41 and liquid inlet 216. Only when the two connectors can be in contact with the corresponding detection probe 41 and liquid inlet 216 and sealed, can it be sufficient.

[0055] Preferably, the direction from the liquid inlet 216 to the detection probe 41 is tilted downward relative to the horizontal direction, that is, the horizontal position of the second joint 32 is higher than the horizontal position of the first joint 31, and the second joint 32 and the first joint 31 are staggered relative to the horizontal direction, which can ensure that the source liquid in the liquid flow path fully flows through the detection probe 41, the temperature detection is more reliable, and the optimal milk output temperature is guaranteed. In addition, the tilted setting can ensure that the installation space of the main body 21 of the emulsification equipment and the temperature sensor 40 is more compact. The tilt angle α is set between 10°-45°, preferably 20°-30°, which can ensure smooth milk suction and reliable temperature detection. In other embodiments, the direction from the liquid inlet 216 to the detection probe 41 can be set horizontally, or in a vertical direction, or tilted upward relative to the horizontal direction, all of which can realize the detection of the temperature of the source liquid while transporting the source liquid.

[0056] like Figure 7 As shown, the first connector 31 also includes a liquid jack 312. The first jack 311 is a probe jack that connects to the detection probe 41, while the liquid jack 312 is connected to the catheter. The connection direction between the probe jack and the detection probe and the liquid input direction of the liquid jack 312 are arranged along the same straight line. This means that after entering the connector, liquid flows directly toward the detection probe 41, ensuring sufficient contact with the detection probe 41, ensuring more accurate detection results.

[0057] like Figure 8 As shown, in another embodiment, the connection direction between the probe jack and the detection probe 41 is arranged at an angle to the liquid input direction of the liquid jack. That is, the source liquid flows toward the detection probe along a direction at an angle to the extension direction of the detection probe 41, which can also fully contact the detection probe 41, and the flow of the source liquid is smoother.

[0058] Furthermore, a communication channel 313 is formed between the first connector 31 and the second connector 32. The communication channel 313 extends in a straight line at an angle to the connection direction between the first connector 31 and the detection probe 41, and the connection direction between the second connector 32 and the liquid inlet 216, respectively. This linear communication channel 313 simplifies the structure of the first and second connectors 31 and 32. Furthermore, since a Venturi device requires a certain amount of suction force, a straight channel facilitates the suction of milk into the mixing chamber 211 without affecting the production of milk froth.

[0059] Furthermore, the second connector 32 includes a second receptacle 322. The second connector 32 can also be configured with a preset elasticity variable to facilitate a sealed connection with the liquid inlet 216. Both the first connector 31 and the second connector 32 are configured as receptacles, ensuring consistent connection between the detection probe 41 and the liquid inlet 216. In this embodiment, the emulsifying device 100 also includes a third connector 33 connected between the second connector 32 and the liquid inlet 216. The third connector 33 is configured as a two-end plug-in post, with one end inserted into the second receptacle 322 of the second connector 32 and the other end inserted into the liquid inlet 216. This facilitates removal and cleaning of the second and third connectors 32, 33. The emulsifying device 100 also includes a fourth connector 34, which is connected between the conduit and the liquid receptacle 312 and can be considered a milk pipe connector. Thus, connection between the container and the liquid inlet 216 can be achieved by simply providing a conduit from the container to the fourth connector 34. Connection and removal of each connector are very simple, making cleaning of each connector easy.

[0060] The housing 50 of the emulsifying device 100 includes a front shell 51 and a rear cover 52 joined together along the front and rear sides. The front shell 51 is provided with a first opening 511 and a second opening 512 spaced apart. The third connector 33 extends from the first opening 511, and the detection probe 41 extends from the second opening 512. The temperature sensor 40 includes a connecting terminal 42 connected between the detection probe 41 and the wire, and the connecting terminal 42 is supported on the rear cover 52. The temperature sensor 40 is secured to the rear cover 52, with the detection probe 41 extending from the opening in the front shell 51, ensuring a more secure connection of the temperature sensor 40.

[0061] Specifically, Figure 8 Coordinate Reference Figure 2The rear cover 52 is provided with a forward-extending support rib 522. The free end of the support rib 522 is provided with a support groove 523 that matches the shape of the connecting end 42 of the temperature sensor 40. The connecting end 42 is supported in the support groove 523, and the detection probe 41 extends from the second opening 512. A flange 513 is formed on the front shell 51 at a position corresponding to the second opening 512. The second opening 512 is formed in a hole shape with a depth greater than the wall thickness of the front shell 51. This can increase the contact area between the temperature sensor 40 and the front shell 51, not only ensuring the stability of the support for the detection probe 41, but also fixing the position of the entire temperature sensor 40, preventing the temperature sensor 40 from sliding back and forth within the shell 50, and ensuring that the detection probe 41 of the temperature sensor 40 is exposed and fully in contact with the milk.

[0062] In this embodiment, the detection probe 41 of the temperature sensor 40 is encased in metal, offering high conductivity. It is assembled on the housing 50 and can be accessed by removing the first connector 31, making it easy to clean. Prolonged contact between the detection probe 41 of the temperature sensor 40 and milk can easily lead to the formation of milk scale, which can render the sensor insensitive. Encasing it in metal not only improves conductivity but also facilitates cleaning. When a Venturi device is used to draw in milk of varying temperatures, the hot milk and hot milk froth produced by the Venturi device have different temperatures, affecting the taste and quality of the milk coffee. The temperature sensor 40 of the present invention is mounted on the housing 50 of the emulsifying device and, encased in metal, offers high temperature conductivity, enabling real-time monitoring of milk temperature. Each time hot milk / milk froth is produced, the temperature sensor quickly detects the real-time temperature within 3-5 seconds. The controller responds to the temperature sensor's output by controlling the milk flow rate, steam temperature / flow rate, and other factors.

[0063] Continue to refer to Figure 2 and Figure 3An adjustment element 23 is installed within the milk inlet channel 212 of the main body 21. A stepper motor 25 drives the adjustment element 23 to rotate, adjusting the amount of milk fed into the mixing chamber 211. An inlet slot is formed on the adjustment element 23. Rotation of the adjustment element 23 relative to the main body changes the cross-sectional area of ​​the inlet slot. The controller adjusts the milk inlet cross-section at different levels based on the real-time milk temperature detected by the temperature sensor 40, ensuring the optimal temperature and taste of the milk at the outlet. When the conduit draws in milk of varying temperatures, the temperature sensor monitors the temperature in real time. Even with these temperatures, the NTC temperature sensor reacts in just 3-5 seconds. The inlet slot cross-section is adjusted in real time to ensure a gradual increase in milk temperature, ensuring the desired temperature and taste of a cup of milk coffee. Taking a coffee machine as an example, when you need to make a cup of milk coffee that requires both hot milk and hot milk foam, such as cappuccino or macchiato, the milk and milk foam need to be in a fixed order to ensure that the milk foam comes out first and the milk comes out later. The coffee machine follows the pre-set program and recipe. When the production program requires hot milk, the temperature is detected in real time through the temperature sensor. The rotation of the stepper motor 25 adjusts the adjustment element 23 to the section for entering the corresponding milk foam. When the production program requires milk, it rotates accordingly to the section for making milk.

[0064] The stepper motor 25 is only one form of a driving device. A driving device is added above the milk frother provided with a venturi device. Any driving mode can be used as long as it can achieve a certain angle of rotation.

[0065] In addition, the controller can also respond to the output of the temperature sensor 40 by issuing a high or low temperature alarm. For example, when making milk coffee, if high-temperature milk above 26°C is temporarily used (for example, in some high-temperature areas or in hot weather) or if the user mistakenly uses high-temperature milk, milk foam may splash, affecting the user's operating experience. The temperature sensor 40 detects the temperature in real time and responds quickly, providing a timely high-temperature alarm. For example, the screen will issue an interface reminder and stop the production of milk / beverages at the same time, which can effectively prevent the occurrence of splashing problems and ensure user safety.

[0066] Reference Figure 9 Cooperate Figure 2 and Figure 3 The main body 21 of the emulsifying device 100 is detachably connected to the housing 50. A beverage outlet 55 is also provided in the housing 50. The liquid outlet 215 is located in front of the beverage outlet 55, and the detection probe 41 is located behind the liquid inlet 216. The main body 21 is located in front of the beverage outlet 55, making it easy to remove the main body 51, which serves as a venturi device, for deep cleaning, thereby preventing the accumulation of milk residues during long-term use and posing a health hazard to the user.

[0067] A portion of the main body 21 is housed within the support cover 26, and the main body 21 is detachably connected to the housing 50 via the support cover 26. Cantilevered pressure plates 261 are provided on the left and right sides of the support cover 26, each with a hook 262. Correspondingly, a slot 516 is provided on the front housing 51. The support cover 26 drives the main body 21 upwardly into the front housing 50 until the hook 262 sinks into the slot 516, thereby securing the main body 21 within the front housing 51. Pressing the pressure plates 261 on both sides disengages the hook 262 from the slot 516, thereby enabling the main body 21 to be removed from the front housing 51. Furthermore, the housing 50 further includes a decorative cover 53 disposed on the front portion of the front housing 51. The decorative cover 53 is detachably connected to the front housing 51 to cover the opening at the front of the front housing 51 and the slot 516, thereby enhancing the appearance of the emulsification device.

[0068] In the above embodiment, the emulsifying device 100 can be an independent milk frother, or it can be installed on the beverage machine and connected to the steam source of the beverage machine. The emulsifying device can be independent of the outlet component of the beverage machine, or the beverage outlet of the beverage machine can be integrated into the emulsifying device.

[0069] Reference Figure 10 The present invention also relates to a beverage machine 10, comprising a main body 11, wherein the main body 11 is provided with an emulsifying device 100 as described in the above embodiment. The beverage machine can be a tea machine, coffee machine, milk tea machine, or other device for brewing beverages. The temperature sensor can be disposed in the housing of the emulsifying device, or alternatively, the housing of the beverage machine.

[0070] The emulsifying device and beverage dispenser of the present invention utilizes a detachable connector provided in the liquid flow path from the container to the mixing chamber to connect it to the temperature sensor's detection probe. This eliminates the need to pre-place the temperature sensor in the milk container for temperature measurement. The detection probe is detachably connected via a first connector, making it easy to disassemble. Removing the first connector exposes the detection probe, making it easy to clean. The detection probe also monitors milk temperature in real time, ensuring optimal milk delivery temperature. Regardless of whether the user is using room temperature or low temperature milk, the temperature sensor can monitor the milk temperature near the milk inlet in real time, ensuring the temperature of the finished hot milk or milk foam. This provides a quick response time and ensures a cup of milk coffee that meets the required temperature and taste. If the user mistakenly uses high temperature milk, a timely high temperature alarm is issued to prevent milk foam from splashing and affecting the user, ensuring a superior user experience. Furthermore, the temperature sensor is located within the dispenser, eliminating the need to pre-place the temperature sensor in the milk container for temperature measurement. The connector connecting the temperature sensor and the milk pipe makes cleaning and disassembly easy, and allows for real-time milk temperature monitoring, ensuring optimal milk delivery temperature.
