DETAILED DESCRIPTION
[0047] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. The utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
[0048] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.
[0049] See also Figure 1 The utility model provides a beverage preparation device 200, which is used to prepare hot drinks. Specifically, the beverage preparation device 200 can be a full coffee machine, soy milk machine, etc. with grinding and brewing functions, or it can be a capsule coffee machine, soy milk brewing machine, etc. that brews pre-made raw material powder to prepare beverages.
[0050] See also Figures 2 to 5 The utility model also provides a beverage heating device 100. The beverage heating device 100 can be arranged in the body of the beverage preparation device 200, or can be arranged outside the beverage preparation device 200 and connected to the beverage outlet 203 of the beverage preparation device 200. The beverage heating device 100 can also be a separate product independent of the beverage preparation device 200. In this embodiment, the beverage heating device 100 is used to mix the beverage with a high-temperature heating fluid to achieve a rapid heating function of the beverage. The heating fluid can be high-temperature air, water vapor, etc. Preferably, the heating fluid is high-temperature steam provided by a steam boiler. In this embodiment, the beverage preparation device 200 is taken as a coffee machine as an example for description, and the heated beverage can be milk or milk foam prepared from milk.
[0051] Specifically, see Figure 1The beverage preparation device 200 further includes a heating fluid supply device 201 and a beverage supply device 202. The heating fluid supply device 201 is used to provide heating fluid to the beverage heating device 100. Specifically, the heating fluid supply device 201 may be a steam boiler. The steam boiler may provide high-temperature steam to the beverage heating device 100 by using high pressure, and may control the beverage heating temperature by adjusting the steam intake time, intake pressure and / or intake temperature. The beverage supply device 202 provides beverages to the beverage heating device 100. Specifically, the beverage supply device 202 may include a milk storage container and a milk pump. The milk pump pumps the milk in the milk storage container into the beverage heating device 100. Preferably, the beverage supply device 202 may also include a frothing mechanism. The frothing mechanism is connected to the milk storage container and prepares milk foam. The milk pump may pump milk or milk foam into the beverage heating device 100 as needed.
[0052] For further information, please refer to Figures 2 to 5 The beverage heating device 100 provided by the utility model includes an external body 10, a first input pipeline 20 and a second input pipeline 30 arranged in the external body 10, wherein the material structure of the external body 10 is not limited, for example, it can be made of stainless steel, and has a cylindrical cavity 11 inside.
[0053] Specifically, the cylindrical cavity 11 may have a shape approximating a cylinder or an elliptical cylinder, and its structure is conducive to the fluid flowing into the cavity to form a spiral. It should be noted that in the present invention, the axial direction refers to a direction parallel to or coincident with the axis of the cylindrical or elliptical cylindrical cylindrical cavity 11, the radial direction refers to a direction perpendicular to the axial direction and passing through the axis of the cylindrical cavity 11, and the tangential direction refers to a direction perpendicular to both the axial direction and the radial direction and passing through the outer periphery of the cavity 11.
[0054] Generally speaking, the cavity 11 has a first end 101 and a second end 102 which are arranged opposite to each other in the axial direction, wherein the first input pipeline 20 is connected to the first opening 22 of the cavity, and the second input pipeline 30 is connected to the second opening 30 of the cavity, both of which are located at the first end 101 of the cavity 11, and the outlet for leading the fluid out of the cavity is arranged at the second end 102 of the cavity 12, so as to provide the two fluids with a mixing path as long as possible in the cavity. Preferably, the axial direction extends in the up-down direction, the lower end of the cavity constitutes the first end 101, and the upper end constitutes the second end 102, and under the rising action of the heating fluid, i.e., steam, the two fluids can fill the cavity 11, and are fully mixed and then led out from the outlet. In this way, the space inside the cavity 11 is fully utilized, so that the heating fluid and the beverage are mixed as evenly as possible, and the heating effect is good.
[0055] The first input pipeline 20 and the second input pipeline 30 can be fixedly connected to the external body 10, or can be integrally formed with the external body 10. The first input pipeline 20 is used to connect to the heating fluid supply device 201, for example, to directly or indirectly connect to the steam boiler, and the first input pipeline 20 has a first input channel 21 connected to the cavity 11, that is, the first input channel 21 is at least formed in a section of the first input pipeline 20 adjacent to the external body 10, and the first input channel 21 introduces the high-temperature heating fluid into the cavity 11 through the first opening 22.
[0056] In this embodiment, please refer to Figure 3 , Figure 3 The dashed arrow in the middle indicates the flow direction of the fluid entering the cavity 11. As shown in the figure, the first input channel 21 extends along the tangential direction of the cavity 11, so that the heating fluid has kinetic energy to extend along the tangential direction of the cavity 11 in the initial stage of entering the cavity 11, and generates centripetal force under the guidance of the arc-shaped inner wall of the cavity 11, forming a spiral flow path rotating around the axis. It should be noted that in other embodiments, the first input channel 21 is not completely parallel to the tangential direction, but can have a certain inclination angle with the tangential direction, as long as the axial projection of the first input channel 21 is maintained to extend along the tangential direction. In a preferred embodiment, as Figure 8 As shown, the first input channel 21 is inclined in the direction toward the first opening 22 and away from the outlet. In particular, when the outlet is arranged at the upper end of the cavity 11, the first input channel 21 is inclined downward. In this way, the upward evaporation trend of the high-temperature steam when it is introduced into the cavity 11 is slowed down, and its flow time inside the cavity 11 is delayed to better heat the beverage.
[0057] The second input pipe 30 is used to connect to the beverage supply device 202, for example, to directly or indirectly connect to the milk storage container. The second input pipe 30 has a second input channel 31 connected to the cavity 11, that is, the second input channel 31 is at least formed in a section of the second input pipe 30 adjacent to the outer body 10. The second input channel 31 introduces the beverage to be heated, such as milk or milk foam, into the cavity 11. In this embodiment, please refer to Figure 3 , Figure 3 The dashed arrow in the middle indicates the flow direction of the fluid entering the cavity 11. As shown in the figure, the second input channel 31 extends along the tangential direction of the cavity 11, so that the beverage has kinetic energy extending along the tangential direction of the cavity 11 in the initial stage of entering the cavity 11, and generates centripetal force under the guidance of the arc-shaped inner wall of the cavity 11, forming a spiral flow path rotating around the axis.
[0058] It should be noted that, in other embodiments, the second input channel 30 is not completely parallel to the tangential direction, but may have a certain inclination angle with the tangential direction, as long as the axial projection of the second input channel 31 is maintained to extend along the tangential direction. Fig. 9 As shown, the second input channel 31 is inclined in the direction toward the second opening 32 and toward the direction close to the outlet. In particular, when the outlet is arranged at the upper end of the cavity 11, the second input channel 31 is inclined upward, thereby providing an upward force for the beverage introduced into the cavity 11, reducing the tendency of the beverage to sink to the bottom of the cavity 11 due to gravity, improving the heating efficiency, and reducing the deposition of the beverage in the cavity 11.
[0059] For further information, please refer to Figure 2 and Figure 3 In this embodiment, the first opening 22 and the second opening 32 are located at the same axial position, that is, the first opening 22 and the second opening 32 are located at the same axial height. This allows the heating fluid and the beverage entering the cavity 11 to mix with each other immediately, prolonging the mixing path through which the two flow together, increasing the mixing time, and thus improving the heating efficiency of the heating device.
[0060] In another embodiment, please refer to Figure 3 and Figure 7 , the first opening 22 and the second opening 32 are staggered in the axial direction, the distance between the center point of the first opening 22 and the center point of the second opening 32 in the axial direction is S, the maximum size of the cavity 11 in the axial direction is H, S / H is greater than 0 and less than or equal to 0.1. In this way, the positions where the heating fluid and the beverage are introduced into the cavity 11 are staggered in the axial direction by a certain distance, which avoids the mutual disturbance of the two fluids and affects the formation of the vortex, while not affecting the mixing and heating effect of the two.
[0061] Optionally, to ensure vortex formation, see Figure 3 , the inner diameter of the first input channel 21 is a, the inner diameter of the second input channel 31 is b, the maximum radial dimension of the cavity 11 is D, a / D is greater than or equal to 0.2 and less than or equal to 0.4, and b / D is greater than or equal to 0.2 and less than or equal to 0.4. The first input channel 21 and the second input channel 31 within this value range are conducive to avoiding the phenomenon that the fluid kinetic energy is too small to form a vortex, or the fluid introduced kinetic energy is too high, causing turbulence to fail to form a vortex.
[0062] In this embodiment, please refer to Figure 3The first opening 22 and the second opening 32 are arranged opposite to each other in the radial direction. In this way, the positions where the two fluids enter the cavity 11 are as far apart as possible, avoiding the loss of kinetic energy caused by the mutual interference of the two fluids in the initial stage of entering the cavity 11. In an optional embodiment, please refer to Fig.11 The first opening 22 and the second opening 32 are located on the same radial side of the cavity 11. In this way, when the fluids introduced from the first input channel 21 and the second input channel 31 have the same flow direction, the two fluids can form a vortex flow path together, thereby enhancing the kinetic energy of the fluid and improving the heating efficiency.
[0063] It can be understood that based on the above embodiments, please refer to Figure 3 and Fig.11 , preferably, the flow direction of the fluid introduced into the first input channel 21 and the second input channel 31 is the same. Specifically, the first input channel 21 and the second input channel 31 are both close to the cavity 11 in a clockwise direction, or the first input channel 21 and the second input channel 31 are both close to the cavity 11 in a counterclockwise direction. In other words, the flow directions of the fluid injected into the cavity 11 by the first input channel 21 and the second input channel 31 are consistent, and the kinetic energy between the two will not cancel each other out, but enhance each other. In this way, the heating fluid and the beverage can flow and mix together along a spiral path in the cavity 11, which effectively improves the mixing efficiency and heating uniformity between the beverage and the heating fluid compared to the method in which one of the input channels is connected to the cavity 11 axially, thereby making the control of the beverage heating temperature more precise and improving the overall quality of the finished beverage.
[0064] In other optional embodiments, see Fig.10 The first input channel 21 and the second input channel 31 may also have opposite directions, so that the vortex paths of the heating fluid and the beverage fluid are opposite, and the kinetic energy of the two fluids is reduced after they meet, slowing down the flow speed of the fluid in the cavity 11, thereby extending the mixing time and enhancing the heating effect.
[0065] Based on the above examples, please continue to refer to Figure 3 and Figure 5The beverage heating device 100 further includes an inner body 40 disposed in the cavity 11. The cavity 11 includes an input cavity 111 defined between the outer circumference of the inner body 40 and the outer body 10. The cross section of the input cavity 111 in the axial direction is annular, specifically, a perfect circular ring or an elliptical ring. The first input channel 21 and the second input channel 31 are both connected to the input cavity 111. In this embodiment, the inner body 40 is preferably integrally formed with the outer body 10, and its shape is preferably consistent with the inner contour of the cavity 11, preferably cylindrical, conical or truncated cone. In one embodiment, please refer to Figure 5 The inner body 40 is arranged in a columnar shape with the axis extending axially to play a good guiding role. Figure 6 , the inner body 40 is arranged in a conical or truncated cone shape with the axis extending axially, and the cross-sectional dimension of the inner body 40 in the axial direction is gradually reduced from the first end 101 to the second end 102. In this way, on the one hand, it is easy to demould and manufacture during the process of integrally forming the inner body 40 and the outer body 10, and on the other hand, in the path where the two fluids flow and mix along the spiral path, the flow cross-section gradually increases and the flow rate gradually slows down, thereby reducing the kinetic energy loss and prolonging the mixing time of the two fluids. Preferably, in this embodiment, the taper of the conical or truncated cone-shaped inner body 40 is greater than or equal to 0.5 and less than 1.
[0066] In this embodiment, the internal body 40 serves to guide the fluid entering the cavity 11 in the initial stage, so that the two fluids enter the cavity 11 and flow around the internal body 40 respectively to form a spiral flow path, thereby preventing part of the fluid from flowing directly along the axial direction to the output channel 61, thereby extending the flow path for the heating fluid and the beverage to flow together, extending the mixing flow time of the heating fluid and the beverage, and improving the heating efficiency and the heating uniformity of the beverage.
[0067] Preferably, the outer body 10 and / or the inner body 40 can be configured as a heating source, and the cavity 11 can be preheated before the heating fluid is introduced into the cavity 11. While improving the heating efficiency, it can also prevent water vapor from condensing inside the cavity 11 to form water droplets to dilute the beverage and affect the taste of the finished beverage. Preferably, the inner body 40 is configured as a heating source. On the one hand, heating is performed from inside the cavity 11 to reduce heat loss and energy consumption. On the other hand, the space inside the inner body 40 can be used to set a heating component 50 such as a heating wire to avoid the heating device being too large, making the heating device structure more compact.
[0068] Optionally, one end of the inner body 40 in the axial direction is located at the first end 101, and the other end of the inner body 40 in the axial direction is located between the first end 101 and the second end 102. In this embodiment, the inner body 40 extends from the first end 101 close to the first input channel 21 and the second input channel 31 in the cavity 11 to the second end 102 provided with an outlet. The cavity 11 further includes an output cavity 112 defined and formed between the end side of the inner body 40 close to the second end 102 and the second end 102, and the outlet is adjacent to the output cavity 112. Preferably, the beverage heating device 100 further includes an output pipeline 60, the output pipeline 60 is used to connect the beverage outlet 203, and form an output channel 61 connected to the cavity 11 through the outlet, and preferably the output channel 61 extends in the axial direction.
[0069] In this way, the cavity 11 is divided into an annular input cavity 111 and an output cavity 112 with a larger space, which are arranged in sequence along the fluid flow direction. In this way, the heated fluid and the beverage form a spiral flow path for full mixing when entering the input cavity 111. In the output cavity 112, the space is enlarged, the flow rate is slowed down, and the mixing time of the two fluids is prolonged. Finally, they are fully mixed, heated evenly, and then flow to the input channel.
[0070] It can be understood that if the size of the input cavity 111 is too small, the spiral fluid power formed will be insufficient and cannot play a good mixing role. If the size of the input cavity 111 in the axial direction is too large, the size of the output cavity 112 will be too small and the mixing time of the two fluids will be too short. Therefore, in a preferred embodiment, the maximum size of the inner body 40 in the axial direction is h, and the maximum size of the cavity 11 in the axial direction is H, and h / H is greater than or equal to 0.4 and less than or equal to 0.6; and / or, the maximum size of the inner body 40 in the radial direction is d, and the maximum size of the cavity 11 in the radial direction is D, and d / D is greater than or equal to 0.6 and less than or equal to 0.8. In this way, the size ratio of the input cavity 111 and the output cavity 112 is appropriate, which is conducive to the full mixing and uniform heating of the beverage and the heating fluid.
[0071] Further, the axial direction of the cavity 11 extends in the up-down direction, the output cavity 112 is located above the input cavity 111, and the outlet is opened at the upper end of the main body 10. Preferably, the output channel 61 extends in the up-down direction and communicates with the cavity through the outlet opened at the upper end of the main body 10. In this embodiment, the output channel 61 extends in the axial direction and extends upward from the outlet to guide the heated beverage toward the beverage outlet direction.
[0072] Preferably, a temperature sensor is provided in the output channel 61 or in the cavity 11 near the output channel 61, and the temperature sensor is used to sense the temperature of the heated beverage and feed back to the heating fluid supply device 201 to control the supply time, supply pressure and / or supply temperature of the heating fluid by the heating fluid supply device 201, thereby achieving precise control of the heating temperature of the finished beverage.
[0073] Obviously, the above described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, ordinary technicians in this field can make other different forms of changes or modifications without creative work, which should fall within the scope of protection of the utility model.
