Description

Technical Field

[0001] This application relates to the technical field of coffee machines, specifically to a coffee machine dispensing structure and a method for blending coffee liquid. Background Technology

[0002] In espresso machines, the resulting coffee is particularly noticeable and important. This is achieved through a high-temperature, high-pressure extraction system. Due to the machine's structure, several factors, including the appropriate amount and fineness of coffee grounds, and the appropriate tampering pressure, must be met simultaneously to achieve high-quality extraction and obtain a rich, crema-rich espresso. Because this requires a high level of operator skill, most machines on the market currently do not address this issue, leaving it to the user to improve their own coffee-making abilities. To address this, we aim to lower the requirements and make it easier for users to obtain their ideal coffee.

[0003] Generally, coffee brewing methods fall into three main categories. The first type involves no extraction structure, directly drawing the coffee liquid out. The drawback of this method is that the finished coffee is not ideal. The second type uses a back pressure valve at the outlet to provide extraction pressure. The main drawbacks of this method are its complex structure, high cost, and difficulty in cleaning. The third type adds a multi-layered fine filter structure at the outlet to achieve blending of the coffee liquid. The main drawbacks of this method are that the filters are difficult to clean, increase costs, and the filters are prone to falling off and being lost. Summary of the Invention

[0059] Specifically, in this embodiment, the product is used in conjunction with an espresso machine. The espresso machine generates a high-pressure liquid flow. Multiple spray nozzles on the espresso machine simultaneously spray water at high pressure onto the coffee powder container 2 to form a high-pressure liquid flow. This high-pressure liquid flow enters the coffee powder container 2 perpendicular to the bottom surface of the container. The pressure range is 0.2-1.2 MPa, more preferably 0.5-0.9 MPa. The temperature range is 5-95 degrees Celsius, more preferably 2-30 degrees Celsius and 70-85 degrees Celsius (based on the application scenarios). The handle funnel 1 includes a handle portion and a funnel portion connected to each other. A mounting cavity 11 is formed on the funnel portion. The upper end of the handle funnel 1 is open and communicates with the mounting cavity 11. A coffee powder holder 2 and a dispensing rack are arranged sequentially from top to bottom inside the mounting cavity 11. The outer wall of the coffee powder holder 2 is connected to the edge of the funnel portion of the handle funnel 1. The coffee powder holder 2 includes a first body 23 and a second body 24 integrally formed. A placement cavity 25 is formed on the first body 23 to prevent coffee and hot water from brewing.

The protrusion can slide in the sliding groove and rotate in the rotating groove. When installation is required, align the protrusion with the sliding groove, press down on the coffee powder bowl 2 so that the protrusion slides down the sliding groove, and then rotate the coffee powder bowl 2 so that the protrusion rotates in the rotating groove, which can facilitate the installation of the coffee powder bowl 2.

[0060] Specifically, in this embodiment, the dispensing rack 3 is provided with a fixing groove with an open top. The bearing surface (bottom of the fixing groove) of the dispensing rack 3 is provided with a first protrusion 31 and a second protrusion 32. The second protrusion 321 surrounds the outside of the first protrusion 311 and is located within the fixing groove of the dispensing rack 3. The first protrusion 311 and the second protrusion 321 are cylinders with holes in the middle. The sidewall of the first protrusion 31 and the bearing surface of the dispensing rack 3 together form a second mixing cavity 33. A first connecting channel 34 is provided on the first protrusion 31. The first protrusion 31 is divided into left and right second protrusions. A first protrusion 311 is formed, with gaps between the left and right sides of the two first protrusions 311 to form two first connecting channels 34. The upper surfaces of the two first protrusions 311 are both wavy curved surfaces. The inner diameter of the first connecting channels 34 gradually increases from bottom to top. The bottom of the second mixing chamber 33 is higher than the bottom of the first connecting channels 34, allowing some solution to remain in the second mixing chamber 33 for better mixing of coffee liquid. There is a gap between the lower surface of the second body 24 of the portafilter and the wavy curved surface of the upper surface of the first protrusion 311 for air intake and solution mixing. The bottom surface of the second mixing chamber 33 is a spherical concave surface. The upper surface of the first protrusion 31 has a wavy curved surface (or a comb-like shape, a wavy surface is preferred), with a height difference between 0.5-3.5mm, preferably between 0.8-1.5mm, which can effectively control the amount of air entering and the size of the foam overflowing from the coffee liquid. The bottom surface of the second mixing chamber 33 is a spherical concave surface (or a flat surface, a concave spherical surface is preferred).

[0061] Specifically, in this embodiment, the sidewall of the second protrusion 32 and the bearing surface of the liquid separator 3 together form a third mixing chamber 35, and a second connecting channel 36 is provided on the second protrusion 32; the second protrusion 32 is divided into two second protrusions 321, front and rear, and curved ears 322 are provided on the left and right sides of the front and rear sides of the two second protrusions 321. A gap is provided between the two curved ears 322 on the left and right sides of the front side and the two curved ears 322 on the left and right sides of the rear side to form two A second connecting channel 36; a liquid outlet 37 is located in the receiving cavity 39 and between two curved ears 322 located on one side; the curved ears 322 are formed by bending the second protrusion 321 inward, and the curved ears 322 have the function of guiding and restricting the flow; a flow guide rib 38 is provided on the bottom surface of the third mixing cavity 35 near the second connecting channel 36, the flow guide rib 38 is a raised rib, and the flow guide rib 38 is used to guide the coffee liquid flowing out of the first connecting channel 34 to the third mixing cavities 35 on both sides. The second mixing chamber 33 is connected to the third mixing chamber 35 through the first connecting channel 34. The second protrusion 32 and the outer peripheral wall of the dispensing rack are provided with a receiving cavity 39. The receiving cavity 39 and the third mixing chamber 35 are connected through the second connecting channel 36. A dispensing hole 37 is provided in the receiving cavity 39. Dispensing pipes 4 are provided on both sides of the lower end of the dispensing rack. Dispensing channels 41 are provided on the dispensing pipes 4. The dispensing channels 41 are connected to the dispensing hole 37. The coffee liquid is sprayed from the spray hole 22 of the first mixing chamber 21 into the second mixing chamber 33 for re-mixing and then enters the third mixing chamber 35 through the first connecting channel 34 for mixing. After mixing, it enters the dispensing hole 37 through the second connecting channel 36 and flows out through the dispensing channel 41. The lower end of the handle funnel 1 is provided with a mounting hole for receiving the dispensing pipe 4. Part of the dispensing pipe 4 protrudes outside the mounting hole, allowing the user to collect the coffee liquid. The width of the first connecting channel 34 and the second connecting channel 36 is between 1-4 mm, with 1-1.8 mm being optimal, and the opening type being narrower at the bottom and wider at the top being optimal. The first protrusion 31 is an inner annular protrusion formed by the upward protrusion of the bottom wall of the dispensing rack 3; the second protrusion 32 is an outer annular protrusion formed by the upward protrusion of the bottom wall of the dispensing rack 3; the curved ear 322 is formed by the edge of the second protrusion 32 folding inward toward the center of the first mixing chamber 21; the gap between the two curved ears 322 forms the second connecting channel 36; and the extension trajectory of the curved ear 322 on the bottom surface of the dispensing rack 3 is part of the boundary of the liquid outlet 37.

[0062] Specifically, in this embodiment, hot water fills the coffee powder in the coffee bowl 2. Under high pressure, the hot water passes through multiple leakage holes 26 at the bottom of the coffee bowl 2 and enters the first mixing chamber 21. After being mixed in the first mixing chamber 21, the coffee liquid is sprayed out from the spray hole 22 and then tumbles in the concave spherical second mixing chamber 33. At the same time, air enters through the narrow gap formed by the wavy curved surface of the upper end of the first protrusion 31 and the bottom of the coffee bowl 2. Under the action of high-speed rotation, the air is successfully mixed, making the coffee crema more delicate. After the coffee liquid passes through the second mixing chamber 33, as the second mixing chamber 33 is filled, under the pressure of the coffee liquid, it flows into the third mixing chamber 35 along the first connecting channels 34 on both sides. In the third mixing chamber 35, the cavity space becomes larger, the liquid flow rate decreases, and under the action of gravity, the liquid surface becomes shallower and flows slowly. In this process, some of the larger diameter foam can be eliminated, thereby ensuring a more delicate crema. The coffee liquid is decelerated and large bubbles are eliminated in the third mixing chamber 35, and the fine oils are gathered again into the evenly distributed liquid outlet 37, and flow out continuously along the liquid outlet channel 41.

[0063] Specifically, in this embodiment, by setting a first mixing chamber 21, a second mixing chamber 33, and a third mixing chamber 35, the coffee liquid is initially mixed in the first mixing chamber 21 and then enters the second mixing chamber 33 through the spray hole 22 for further mixing. It then flows into the third mixing chamber 35 for further mixing and finally flows out from the outlet hole 37 for the user to consume. This process of re-blending the coffee liquid three times results in a more ideal coffee quality. The structure is simple, the manufacturing cost is low, and the function is stable.

[0064] Specifically, in this embodiment, by setting the upper end of the first protrusion 31 into a wavy curved surface, the amount of air entering and the size of the foam overflowing from the coffee liquid can be well controlled. By setting the guide ribs 38, the coffee liquid can be better guided to flow evenly to the left and right sides. After the coffee liquid is mixed in the first mixing chamber 21, it can also enter the second mixing chamber 33 through the leakage hole 26 under pressure.

[0065] Example 2:

[0066] A method for blending coffee liquid, using the coffee machine dispensing structure as described in Example 1, includes:

[0067] S1: Coffee powder is placed in the placement cavity 25; high-pressure hot water fills the placement cavity 25 and mixes with the coffee powder to form coffee liquid;

[0068] S2: The coffee liquid obtained in step S1 passes through the evenly distributed leakage holes 26 at the bottom of the coffee powder bowl 2 and enters the first mixing chamber 21. After being mixed in the first mixing chamber 21, the coffee liquid is sprayed out from the spray hole 22.

[0069] S3: The coffee liquid enters the second mixing chamber 33 with the concave spherical surface and tumbles, mixing with air during the tumbling process; it flows into the third mixing chamber 35 after passing through the first connecting channels 34 on both sides and being diverted by the baffle ribs. The third mixing chamber 35 is arranged around the second mixing chamber 33.

[0070] S4: After flowing through the third mixing chamber 35, the coffee liquid enters the outlet hole 37 through the second connecting channel 36, and finally flows out continuously along the outlet channel 41.
