Description

Technical Field

[0001] The utility model relates to the technical field of food or beverage preparation, in particular to a beverage preparation machine. Background Art

[0002] In the field of beverage preparation, the beverage powder brewed by a brewer is transported into the brewer through a powder transport channel. Beverage is a kind of food, and the cleaning of the powder transport channel is a key issue.

[0003] At present, most beverage preparation machines on the market adopt a fixed powder transport channel. This design has some defects in the use process. For example, when transporting beverage powder (such as coffee powder), the beverage powder is likely to adhere to the wall of the powder transport channel. Especially to facilitate the transport of beverage powder from the powder transport channel to the brewer, the powder transport channel is often arranged above the brewer. When the brewer brews beverage powder under high temperature and high pressure, the high-temperature steam in the brewer is likely to overflow and rise, making the wall of the powder transport channel wet, which is more likely to cause the beverage powder to adhere, resulting in the accumulation of coffee powder. However, the disassembly and cleaning of the fixed powder transport channel are complex and inconvenient. If not disassembled and cleaned in time, these residual beverage powders are likely to fall into the brewer during the next beverage brewing, which will affect the quality of the beverage and the user experience.

[0004] In addition, the existing powder transport channel design cannot effectively prevent large particles (such as beverage particles, agglomerated beverage powder, and foreign particles) from entering the brewer. After these beverage particles (such as coffee beans) or foreign particles fall into the brewer, they will damage the brewer, affecting the normal use and service life of the equipment. After the agglomerated beverage powder (such as agglomerated coffee powder) falls into the brewer, it will affect the taste of the beverage, further affecting the user experience.

[0005] Therefore, there are still some problems to be urgently solved in the beverage powder transport of the existing beverage preparation machines. Summary of the Invention

[0029] The present utility model will be described in detail below in conjunction with the specific implementation manners shown in the accompanying drawings. However, these implementation manners do not limit the present utility model, and structural, method, or functional transformations made by those of ordinary skill in the art based on these implementation manners are all included in the protection scope of the present utility model.

[0030] It should be understood that the terms indicating relative spatial positions such as "upper", "above", "lower", "below", etc. used herein are for the purpose of facilitating description of the relationship between one unit or feature and another unit or feature as shown in the accompanying drawings. The terms of relative spatial positions may be intended to include different orientations of the device in use or operation other than the orientations shown in the figures.

[0031] An embodiment of the present utility model provides a beverage preparation machine that is convenient to clean, has smooth powder conveyance, can prevent large particles (such as beverage particles, agglomerated beverage powder, or foreign particles) from entering the brewer, and protects the brewer.

[0032] The beverage preparation machine 100 of this embodiment can be a device for brewing beverages such as a tea machine, a coffee machine, a milk tea machine, etc., such as Figure 1As shown, the beverage preparation machine 100 includes a powder delivery fixture 30 and a brewer 50. The powder delivery fixture 30 is located above the brewer 50, and the powder outlet 33 of the powder delivery fixture 30 faces the brewer 50. When it is necessary to brew beverage powder, beverage powder is added into the powder delivery fixture 30, and the beverage powder falls from the powder outlet 33 into the brewer 50 for brewing.

[0033] The powder delivery fixture 30 is not convenient to be disassembled from the beverage preparation machine 100. For the purpose of facilitating disassembly and cleaning, the beverage preparation machine 100 further includes a powder delivery movable member 10. The powder delivery movable member 10 is detachably connected to the powder delivery fixture 30. At least a part of the powder delivery movable member 10 is accommodated in the powder delivery fixture 30. A first powder delivery channel 16 is provided in the powder delivery movable member 10, as Figure 1-3 shown.

[0034] When pouring beverage powder into the first powder delivery channel 16 of the powder delivery movable member 10, since the part of the powder delivery fixture 30 shielded by the powder delivery movable member 10 will not be stained with beverage powder, the shielded part can remain clean. The powder delivery movable member 10 stained with beverage powder can be conveniently and quickly disassembled from the powder delivery fixture 30 for cleaning, and can be conveniently and quickly reinstalled on the powder delivery fixture 30 after cleaning, which can avoid the hygiene problems and maintenance difficulties caused by the long-term accumulation of beverage powder described in the background art.

[0035] The brewer 50 generally brews beverage powder through high temperature and high pressure. The high-temperature steam is likely to overflow from the brewer and enter the first powder delivery channel 16 of the powder delivery movable member 10. When the channel wall of the first powder delivery channel 16 is wet, it is easy to adhere to the conveyed beverage powder. Due to the detachable setting of the powder delivery movable member 10, the powder delivery movable member 10 can be conveniently and quickly disassembled and cleaned, keeping the first powder delivery channel 16 of the powder delivery movable member 10 clean and hygienic, thus facilitating the daily cleaning of the beverage equipment machine.

[0036] In addition, the beverage preparation machine 100 may further include a bean hopper 60 and a bean grinding part 70. The bean hopper 60 is used to place large beverage particles to be ground, such as coffee beans. The bean grinding part 70 is used to grind beverage particles, such as grinding coffee powder. When it is necessary to grind beverage particles, the beverage particles in the bean hopper 60 can enter the bean grinding part 70, and the bean grinding part 70 can grind the entered beverage particles into beverage powder.

[0037] Specifically, ready-made beverage powder can be supplied to the brewer 50 through the first powder delivery channel 16 of the powder delivery movable member 10, or ready-made beverage particles can be ground into beverage powder by the bean grinding part 70 and then supplied to the brewer 50.

[0038] To clearly express the positions and directions described in this embodiment, in this embodiment, since the beverage powder falls into the brewer 50 by its own gravity, the direction of gravity is defined as downwards, the opposite direction is defined as upwards, and the plane perpendicular to the up and down directions is defined as the horizontal plane; the grinding part 70 is arranged on the left side of the brewer 50, and the opposite direction is defined as the right side, and the two sides perpendicular to the up, down, left, and right are the front and the rear respectively. In this embodiment, when brewing, the beverage powder falls from above into the powder conveying movable part 10 and continues to fall down until it falls into the brewer 50, and the grinding part 70 is communicatively arranged below the bean bin 60.

[0039] When disassembling the powder conveying movable part 10 of this embodiment, it can be moved upwards until it is separated from the powder conveying fixed part 30, and when installing, the powder conveying movable part 10 is installed downwards. In addition, the powder conveying movable part 10 can also be arranged on the front, rear, left, and right sides of the beverage maker 100, and a downward-sloping feeding channel can be left inside it.

[0040] A screen structure 13 is arranged at one end of the first powder feeding channel 16 close to the powder outlet 33. The screen structure 13 is used to screen the beverage powder to prevent large particles from entering the brewer 50. The large particles can be, for example, beverage particles, agglomerated beverage powder, or foreign particles. Among them, the foreign particles can be other particles except beverage particles, such as small parts of children's toys. The mesh holes of the screen structure 13 can be set to the required aperture according to the fineness of the required beverage powder. The purpose is that the general beverage powder can fall through the mesh holes, while large particles, such as coffee beans, or agglomerated beverage powder affected by moisture cannot pass through. In this way, it can be ensured that the beverage powder falling into the brewer 50 is the desired one, and the agglomerated coffee powder affected by moisture and deterioration will not fall into the brewer 50 to avoid affecting the taste of the beverage, nor will coffee beans fall into the brewer 50 to avoid damaging the brewer 50. Therefore, the setting of the screen structure 13 can protect the brewer 50 from damage while maintaining normal feeding, and can also ensure the taste of the beverage.

[0041] As Figure 2 shown, the bean bin 60 has a filling opening 61 and a cover 62. The through hole 21 on the support housing 20 in the following description is arranged adjacent to the filling opening 61, and the cover 62 covers the filling opening 61. The user can open the cover 62 and pour beverage particles, such as coffee beans, into the filling opening 61. During the process of pouring coffee beans, if some coffee beans accidentally fall into the first powder feeding channel 16 from the position of the through hole 21, since the screen structure 13 is arranged at the end of the first powder feeding channel 16, the coffee beans will fall above the screen structure 13 and will not fall into the brewer 50, achieving the effect of protecting the brewer 50.

[0042] Furthermore, as Figure 2As shown, the beverage preparation machine 100 further includes a support housing 20. A powder delivery fixing member 30 is disposed below the support housing 20. The powder delivery fixing member 30 is fixedly connected to the support housing 20. The support housing 20 includes a through hole 21 and a peripheral edge 22 surrounding the through hole 21. The powder delivery fixing member 30 includes a feed inlet 31 adapted to the through hole 21, and the feed inlet 31 is aligned with the through hole 21. As Figure 6 shown, the powder delivery fixing member 30 is fixedly connected to the support housing 20 from below the support housing 20 through structures such as bolts and buckles. Without disassembling the support housing 20, the powder delivery fixing member 30 cannot be disassembled.

[0043] As Figure 4 、 7 shown, an abutting portion 14 is provided at one end of the powder delivery movable member 10 away from the screen structure 13. During the detachable connection between the powder delivery movable member 10 and the powder delivery fixing member 30, the powder delivery movable member 10 sequentially passes through the through hole 21 and the feed inlet 31 until the abutting portion 14 abuts against the peripheral edge 22. Each time the powder delivery movable member 10 is reinstalled onto the powder delivery fixing member 30, only the powder delivery movable member 10 needs to be placed into the through hole 21. Under the action of gravity, the powder delivery movable member 10 passes through the feed inlet 31 and falls to the lowest position, and the abutting portion 14 abuts against the peripheral edge 22 to complete the installation. No complex installation is required, and the operation is convenient.

[0044] Continuing as Figure 4 、 7 shown, the powder delivery movable member 10 and the powder delivery fixing member 30 have the same extending direction. The powder delivery fixing member 30 includes a first side wall 32 connected between the feed inlet 31 and the powder outlet 33. The powder delivery movable member 10 includes a second side wall 12 connected between the abutting portion 14 and the screen structure 13. A first powder delivery channel 16 is formed in the second side wall 12. The second side wall 12 is disposed against the inside of the first side wall 32 to limit the second side wall 12 by the first side wall 32. The shapes of the second side wall 12 and the first side wall 32 are similar. They can be closely attached or have a small gap, preventing the production accuracy of the powder delivery movable member 10 and the powder delivery fixing member 30 from being unable to be guaranteed and affecting the assembly. In this way, while maintaining a larger cross-sectional area of the channel of the powder delivery movable member 10 as much as possible, dust, coffee powder, etc. are prevented from entering between the powder delivery movable member 10 and the powder delivery fixing member 30, keeping the first side wall 32 clean.

[0045] Further, the extending direction of the second side wall 12 forms an angle with the height direction of the beverage preparation machine 100. This angle can be inclined to the left and right directions, or inclined to the front and back directions, or can also be Figure 5It is inclined in the left-rear direction as shown, and the inclination directions of the second side wall 12 and the first side wall 32 are determined according to the position of the brewer 50. At this time, the downward installation of the powder conveying movable member 10 has a certain directionality. According to the spatial positions of the brewer 50 and the bean grinding part 70, an included angle is provided between the extending direction of the second side wall 12 and the height direction of the beverage preparation machine 100, which can compact the overall structural layout of the beverage preparation machine 100 and facilitate the miniaturization of the volume of the beverage preparation machine 100.

[0046] The support housing 20 further includes a positioning portion extending on a horizontal plane. The abutting portion 14 includes a limiting portion adapted to the positioning portion, and the positioning portion and the limiting portion are connected in a limiting manner. Through the limiting connection between the positioning portion and the limiting portion, the specific installation direction of the powder conveying movable member 10 can be restricted. On the one hand, it meets the requirement that the extending directions of the second side wall 12 and the first side wall 32 have an included angle with the up-down direction and face the included angle direction when installed in place. On the other hand, it can prevent the powder conveying movable member 10 from shaking or rotating in place and keep it in the expected position, facilitating the foolproof assembly of the powder conveying movable member 10.

[0047] Furthermore, as Figure 5 shown, the positioning portion includes a first positioning portion 24 extending along a first direction and a second positioning portion 25 extending along a second direction. As Figure 4 and 5 shown, the limiting portion includes a first limiting portion 141 adapted to the first positioning portion 24 and a second limiting portion 142 adapted to the second positioning portion 25. The first direction and the second direction intersect on a horizontal plane; the first limiting portion 141 is connected with the first positioning portion 24 in a limiting manner, and the second limiting portion 142 is connected with the second positioning portion 25 in a limiting manner. Through the limiting connection in two directions, the movement of the powder conveying movable member 10 in any direction is restricted, thereby further ensuring its assembly stability and avoiding the dislocation of the powder conveying movable member 10 caused by the movement of the beverage preparation machine 100 or the vibration of the equipment during the bean grinding of the bean grinding part 70.

[0048] Specifically, the first direction may be the width direction of the beverage preparation machine 100, as shown by the X arrow in Figure 5 , and the second direction may be the length direction of the beverage preparation machine 100, as shown by the Y arrow in Figure 5 ; the first direction and the second direction are vertically crossed on a horizontal plane.

[0049] As Figure 4 and 7As shown, the powder conveying movable member 10 includes a first flared opening 15 connected below the abutting portion 14. The upper port of the first flared opening 15 is the powder inlet 11 of the powder conveying movable member 10. From the powder inlet 11 to the screen structure 13, the cross-sectional area of the first powder conveying channel 16 becomes smaller. The first flared opening 15 is configured as an inverted conical opening. The design of the first flared opening 15 is similar to a funnel, making the feeding of beverage powder smoother. It also facilitates the user to pour beverage powder into the powder inlet 11. The relatively large-caliber powder inlet 11 can also avoid blockage problems caused by poor material discharge at the first flared opening 15 and prevent the spillage of beverage powder, thereby improving the efficiency of beverage powder entering the powder conveying movable member 10 and ensuring the continuity and stability of powder conveying.

[0050] The support housing 20 includes a second flared opening 23 connected to the peripheral edge 22. The second flared opening 23 is adapted to the first flared opening 15, and the first flared opening 15 is abutted against the second flared opening 23 to position the first flared opening 15 through the second flared opening 23. The second flared opening 23 has a similar shape to the first flared opening 15 and can also be configured as an inverted conical opening. The first flared opening 15 can be abutted against the second flared opening 23 or there can be a spacing between the first flared opening 15 and the second flared opening 23. The second flared opening 23 provides a stable support for the first flared opening 15 through profiling and limiting. The powder conveying movable member 10 abuts against both the peripheral edge 22 and the second flared opening 23, making the structure more stable.

[0051] Furthermore, the beverage preparation machine 100 further includes a cover plate 80. The cover plate 80 is detachably connected to the support housing 20 and covers the upper part of the powder inlet 11. The cover plate 80 improves the sealing and safety of the powder conveying movable member 10. On the one hand, it prevents dust and accidental sundries from falling into the powder inlet 11, and on the other hand, it prevents moisture from entering the powder inlet 11, ensuring the dryness and hygiene inside the first powder conveying channel 16 of the powder conveying movable member 10. The detachable connection between the cover plate 80 and the support housing 20 facilitates the disassembly and assembly of the cover plate 80, and thus facilitates the powder adding operation of beverage powder and the disassembly and assembly operation of the powder conveying movable member 10.

[0052] In addition, as Figure 2 and 8 shown, a clearance recess 26 is provided on the support housing 20. The clearance recess 26 is arranged close to the cover plate 80 and exposes a part of the side wall of the cover plate 80, as Figure 8 shown. In this way, when the cover plate 80 covers the powder inlet 11 and the user needs to pour beverage powder into the powder inlet 11, the user can conveniently remove the cover plate 80 from the position of the part of the side wall of the cover plate 80 exposed by the clearance recess 26, without the need for other complex and cumbersome structural designs or the assistance of other tools. The design of the clearance recess 26 is simple and ingenious.

[0053] As Figure 1-3As shown, the beverage preparation machine 100 further includes a powder conveying member 40 disposed below the powder conveying fixing member 30. A second powder delivery channel 41 is provided in the powder conveying member 40. The powder outlet 33 is connected to the brewer 50 through the second powder delivery channel 41, and the bean grinding part 70 is connected to the brewer 50 through the second powder delivery channel 41. The screen structure 13 is located above the second powder delivery channel 41. The second powder delivery channel 41 is simultaneously connected to the bean grinding part 70 and the powder conveying movable member 10. The brewer 50 can obtain beverage powder for brewing from two paths. The beverage powder provided by the bean grinding part 70 enters the second powder delivery channel 41 from left to right, and the beverage powder entering from the powder conveying movable member 10 enters the second powder delivery channel 41 from top to bottom. The second powder delivery channel 41 can send beverage powder in both directions into the brewer 50 for brewing. The second powder delivery channel 41 belongs to the common part of the two paths, simplifies the structure of the beverage preparation machine 100, saves the overall cost of the beverage preparation machine 100, and ensures the continuity and stability of the coffee making process.

[0054] Compared with the prior art, the present embodiment has the following beneficial effects:

[0055] Through the detachable connection design of the powder conveying movable member 10 and the powder conveying fixing member 30 of the beverage preparation machine 100, users can easily and conveniently remove the powder conveying movable member 10 that is prone to adhering beverage powder for cleaning, avoiding hygiene problems caused by long-term accumulation of beverage powder, and improving the maintainability and hygiene of the equipment. In addition, the screen structure 13 provided on the powder conveying movable member 10 can effectively prevent large particles (such as beverage particles, agglomerated beverage powder, and foreign particles) from entering the brewer 50 without affecting the normal conveyance of beverage powder, protecting the brewer 50 from damage, and avoiding affecting the taste and flavor of the beverage, thereby enhancing the reliability and service life of the equipment, significantly improving the usability, maintainability, and reliability of the beverage preparation machine 100, and significantly enhancing the user experience.
