Description

Technical Field

[0001] This invention belongs to the field of brewing equipment technology, specifically relating to a brewing system and a coffee machine. Background Technology

[0002] Depending on the type of coffee being brewed, coffee machines can be divided into two categories: drip coffee machines and capsule coffee machines. Drip coffee machines use a spray nozzle to quickly brew coffee grounds, while capsule coffee machines are convenient to use, allowing you to pierce the coffee capsule. Because capsule coffee has excellent shelf life, it can brew coffee with a great taste and texture.

[0003] When brewing coffee grounds, a drip coffee maker's spray nozzle has multiple spray holes. To overcome water surface tension, these nozzles are usually quite large. However, due to its own weight, the water flow is difficult to cover the surrounding nozzles, resulting in water concentrating in the center of the spray nozzle. This leads to poor water uniformity. If the nozzles are reduced in size, the water surface tension makes it difficult to spray out, resulting in uneven water distribution on the coffee grounds. This leads to poor extraction of the coffee grounds and severely affects the flavor of the brewed coffee. Summary of the Invention

[0008] In the above-mentioned brewing system, the water distribution plate includes a water distribution part and a baffle part. The baffle part is disposed on the periphery of the water distribution part, and the baffle part and the water distribution part enclose to form a groove. The end face of the baffle part away from the water distribution part is attached to the body so that the body seals the groove to form the water distribution cavity.

[0009] In the above-mentioned brewing system, a plurality of spray holes are arranged in the water distribution section, and the diameter of the spray holes is 1.5mm-2.5mm. The lower side of the water distribution section is provided with several water guiding components, which correspond one-to-one with and are connected to the spray holes.

[0010] In the above-mentioned brewing system, the water distribution plate is provided with at least one first magnetic suction element, and the main body is provided with at least one second magnetic suction element. The first magnetic suction element and the second magnetic suction element are adapted to each other and correspond one-to-one.

[0011] In the above-mentioned brewing system, the fluid delivery channel includes a delivery section and a spray section; the body has a first surface and a second surface arranged opposite to each other; the delivery section is arranged along the first surface, the spray section has a first end and a second end, the first end of the spray section is connected to the delivery section, and the second end of the spray section passes through the first surface and the second surface and extends into the water distribution chamber.

[0012] In one of the above-mentioned brewing systems, the second surface is provided with an enclosing portion, and the water distribution plate is assembled inside the enclosing portion to form the water distribution cavity.

[0023] When a coffee machine is running, it mixes the coffee powder with heated hot water by directly injecting the heated water. Because the hot water is injected in one go, the mixing speed between the coffee powder and the hot water is very slow and it is easy for the powder to clump together. This results in a longer brewing time and uneven coffee concentration, leading to a poor taste.

[0024] In related technologies, coffee machines typically use a shower head structure 100 at the hot water outlet to even out the water flow. However, since the shower head includes multiple spray nozzles, the water flow is still difficult to cover the surrounding nozzles due to its own weight. As a result, the water flow may be concentrated in a few nozzles in the center of the shower head, leading to poor water uniformity.

[0025] Based on the above-mentioned technical problems, this application provides a brewing system 1000 and a coffee machine, which aims to solve the technical problem of poor water uniformity from the shower head to at least a certain extent.

[0026] Example 1: like Figure 1-6 As shown, this embodiment provides a brewing system 1000, including a shower head structure 100 and a filter basket 200; the shower head structure 100 includes a body 110, a water distribution plate 120, and a fluid delivery channel 130; the water distribution plate 120 is assembled to the body 110, and a water distribution cavity 140 is formed between the water distribution plate 120 and the body 110; the fluid delivery channel 130 is connected to the water distribution cavity 140; the filter basket 200 has a brewing chamber 210, and a fluid outlet is provided at the bottom of the filter basket 200. 220, the shower head structure 100 is mounted on the filter basket 200; wherein, when the brewing system 1000 is in the first stage, the fluid delivery channel 130 is configured to distribute water to the water distribution chamber 140 so that the water covers the water distribution plate 120; when the brewing system 1000 is in the second stage, the fluid delivery channel 130 is configured to distribute high-pressure gas to the water distribution chamber 140 so that the water in the water distribution chamber 140 is evenly sprayed from the water distribution plate 120 into the brewing chamber 210.

[0027] The design concept of the brewing system 1000 in this embodiment is as follows: water is first distributed to the water distribution chamber 140 through the fluid delivery channel 130, and the water spreads in the water distribution chamber 140. Then, high-pressure gas is distributed to the water distribution chamber 140 through the fluid delivery channel 130. The high-pressure gas pressurizes the water so that the water is sprayed out evenly from the water distribution plate 120, thereby improving the uniformity of water output from the shower head structure 100.

[0028] In this embodiment, the water distribution plate 120 is assembled on the body 110, and a sealed water distribution cavity 140 is formed between the water distribution plate 120 and the body 110. During brewing, coffee powder is placed in the brewing cavity 210 of the filter basket 200. The bottom of the filter basket 200 is provided with a fluid outlet 220. Water in the water distribution cavity 140 is sprayed from the water distribution plate 120 into the brewing cavity 210, thereby extracting the coffee powder. The extracted coffee liquid flows out from the fluid outlet 220 at the bottom, completing the preparation of coffee liquid. When the brewing system 1000 is in the first stage, the fluid delivery channel 130 distributes water to the water distribution chamber 140. Water enters the water distribution plate 120, which has tiny spray holes 121. Due to the surface tension of the water, it cannot flow out of the tiny spray holes 121, causing the water to spread within the water distribution plate 120 and cover it. When the brewing system 1000 is in the second stage, the fluid delivery channel 130 distributes high-pressure gas to the water distribution chamber 140. After the high-pressure gas enters the water distribution chamber 140, the water covering the water distribution plate 120 overcomes the surface tension under the pressure of the high-pressure gas and is evenly sprayed out from the tiny spray holes 121 of the water distribution plate 120. This avoids the problem of uneven spraying caused by water flowing out from only some of the spray holes 121. It should be noted that the first and second stages of the brewing system 1000 are repeated to ensure that the brewing system 1000 brews the coffee powder more thoroughly.

[0029] This brewing system 1000, driven by high-pressure gas, allows the water flow to be more widely dispersed when it leaves the water outlet plate of the shower head structure 100. By expanding the spray range of the shower head structure 100, it can cover a larger area in a shorter time, thereby improving spraying efficiency and ensuring that the coffee powder can be sprayed evenly. This enhances the uniformity of the spray from the brewing system 1000 and guarantees that the coffee powder can be extracted evenly.

[0030] Furthermore, because water can flow into the brewing chamber 210 through the entire surface of the water distribution plate 120, the water coverage of the shower head structure 100 is high, and the water flow can evenly enter the brewing chamber 210 of the filter basket 200. This allows the coffee grounds to be subjected to a more uniform water flow impact during extraction, avoiding uneven extraction caused by excessive or insufficient water in certain areas. This uniform wetting condition helps the active ingredients in the coffee grounds to dissolve or be released more fully into the water, thereby improving the quality and consistency of the extracted product.

[0031] The brewing system 1000 includes a water pump (not shown) and an air pump (not shown), both of which are connected to the fluid delivery channel 130. When the brewing system 1000 is in the first stage, the water pump is configured to deliver water to the fluid delivery channel 130. When the brewing system 1000 is in the second stage, the air pump is configured to deliver high-pressure gas to the fluid delivery channel 130.

[0032] In this embodiment, when the coffee machine is making coffee liquid, the machine body 2000 typically has a water tank and a heater. In the first stage of the brewing system 1000, the water pump first delivers the water in the water tank to the heater for heating, and then delivers the heated water to the fluid delivery channel 130. The fluid delivery channel 130 then distributes the water into the water distribution chamber 140 of the brewing system 1000. In the second stage of the brewing system 1000, the water pump stops delivering water to the fluid delivery channel 130, and the air pump delivers high-pressure gas through the fluid delivery channel 130 to the water distribution chamber 140. The high-pressure gas evenly presses the water in the water distribution chamber 140 out of the water distribution plate 120, thereby achieving uniform water spraying in the brewing system 1000.

[0033] It should be noted that water and high-pressure gas share the same fluid delivery channel 130, which can be switched using a three-way valve. For example, the fluid delivery channel 130 is connected to a three-way valve, which connects to both the water pump and the air pump. In the first stage of the brewing system 1000, the three-way valve connects to the water pump and disconnects the air pump, allowing only water to pass through the fluid delivery channel 130. In the second stage of the brewing system 1000, the three-way valve connects to the air pump and disconnects the water pump, allowing only high-pressure gas to pass through the fluid delivery channel 130. This achieves the cyclical switching between the first and second stages of the brewing system 1000, completing the brewing of coffee powder by the brewing system 1000.

[0034] like Figure 2 , 6As shown in Figure 11, the water distribution plate 120 is provided with a plurality of spray holes 121, and the water distribution chamber 140 is connected to the brewing chamber 210 through the spray holes 121. When the brewing system 1000 is in the first stage, the fluid delivery channel 130 distributes water to the water distribution chamber 140, and the water covers the spray holes 121. When the brewing system 1000 is in the second stage, the fluid delivery channel 130 distributes high-pressure gas to the water distribution chamber 140 to drive water to be evenly sprayed into the brewing chamber 210 through the spray holes 121.

[0035] In this embodiment, the water distribution plate 120 is provided with a plurality of spray holes 121, and the water distribution chamber 140 is connected to the brewing chamber 210 through the spray holes 121. It should be noted that although the water distribution chamber 140 and the brewing chamber 210 are connected through the spray holes 121, when the brewing system 1000 is in the first stage, the fluid delivery channel 130 distributes water to the water distribution chamber 140. The water in the water distribution chamber 140 has surface tension, and under the action of its own gravity, it cannot overcome the surface tension and flow into the brewing chamber 210 from the spray holes 121, and the water covers the spray holes 121. When the brewing system 1000 is in the second stage, the fluid delivery channel 130 distributes high-pressure gas to the water distribution chamber 140. The high-pressure gas compresses the water in the water distribution chamber 140 so that the water overcomes the surface tension and is evenly sprayed into the brewing chamber 210 from all the spray holes 121 to fully brew the coffee powder.

[0036] like Figure 11 As shown, the water distribution plate 120 includes a water distribution part 122 and a blocking part 123. The blocking part 123 is disposed on the periphery of the water distribution part 122, and the blocking part 123 and the water distribution part 122 enclose each other to form a groove 124. One end face of the blocking part 123 away from the water distribution part 122 is attached to the body 110 so that the body 110 seals the groove 124 to form the water distribution cavity 140.

[0037] In this embodiment, the enclosure 123 is disposed on the periphery of the water distribution part 122 so that the water distribution plate 120 forms a groove 124. Then, the body 110 and the enclosure 123 are tightly fitted and sealed to form a water distribution cavity 140, which can provide space for water or high-pressure gas.

[0038] like Figure 2 , 6 As shown in Figure 11, a plurality of spray holes 121 are arranged on the water distribution section 122, and the diameter of the spray holes 121 is 1.5mm-2.5mm; a plurality of water guides 1221 are provided on the lower side of the water distribution section 122, and the water guides 1221 correspond one-to-one with the spray holes 121 and are connected to each other.

[0039] In this embodiment, the spray holes 121 are arranged throughout the water distribution section 122, so that when the water is sprayed from the water distribution plate 120, it can spread to different parts of the water distribution chamber 140, ensuring more uniform extraction of coffee powder. Typically, the diameter of the spray holes 121 is 1.5mm-2.5mm. Thus, in the first stage of the brewing system 1000, due to the small diameter of the spray holes 121, water cannot drip from the spray holes 121 into the brewing chamber 210 due to its own gravity under the action of surface tension.

[0040] In related technologies, hot water is typically used for coffee extraction. When the hot water flows onto the coffee grounds, it generates steam. This steam condenses on the outside of the water distributor 122. Furthermore, some water mixes with the condensate during the spraying process, increasing the amount of condensate on the outside of the water distributor 122. The high surface tension of the condensate causes it to condense into larger droplets before falling. However, the location of these droplets is unpredictable, and the amount of water in each droplet cannot be controlled, resulting in uneven distribution of the coffee grounds and affecting extraction. In some embodiments, in order to further achieve uniform extraction of coffee powder, a plurality of water guides 1221 are provided on the lower side of the water distribution section 122. The lower side of the water distribution section 122 is the side away from the water distribution chamber 140. The water guides 1221 are located outside the water distribution chamber 140. The water guides 1221 are arranged around the spray hole 121 and communicate with the spray hole 121. The outer surface of the water guides 1221 is a sloping conical column and is hollow. The water guides 1221 extend toward the brewing chamber 210. Specifically, when water vapor condenses on the lower side of the water distribution section 122, the condensate drips down the water guide 1221 under the influence of gravity. During the dripping process, the condensate near the water guide 1221 is pulled, guiding the condensate on the lower side of the water distribution section 122 to the water guide 1221. This prevents the condensate from irregularly accumulating and forming large water droplets on the lower side of the water distribution section 122. The condensate is dispersed into small streams or droplets, which drip down below the water guide 1221. This reduces the uncertainty of droplet accumulation and tension, and makes the droplet position and volume more controllable, ensuring that the condensate dripping position is definite and the dripping volume is small. When these small droplets or streams come into contact with the coffee grounds again, they can more evenly wet the coffee grounds, improving extraction efficiency. Furthermore, the outer surface of the water guide 1221 is inclined, and the radius of the water guide 1221 gradually decreases from the end near the water distribution section 122 to the end away from the water distribution section 122, which facilitates the sliding of condensate. The inclined surface faces the center of the water guide 1221. When the inclined surface guides the water flow, it allows the water flow to flow in the direction of the central axis of the water guide 1221, preventing condensate from dripping outside the brewing chamber 210. This not only reduces the accumulation of water droplets and the uncertainty of falling due to tension, but also makes the droplet position and water volume more controllable.

[0041] In the above-mentioned brewing system 1000, the water distribution plate 120 is provided with at least one first magnetic suction member 125, and the body 110 is provided with at least one second magnetic suction member 111. The first magnetic suction member 125 and the second magnetic suction member 111 are adapted to each other and correspond one-to-one. The first magnetic suction member 125 and the second magnetic suction member 111 are attracted to each other so that the water distribution plate 120 is assembled on the body 110.

[0042] In this embodiment, the water distribution plate 120 is provided with at least one first magnetic attractor 125, preferably two first magnetic attractors 125, which can be disposed on opposite sides of the water distribution plate 120. The body 110 is provided with at least one second magnetic attractor 111, preferably two second magnetic attractors 111. The attraction between the first magnetic attractor 125 and the second magnetic attractor 111 ensures that the water distribution plate 120 is more stable and securely assembled on the body 110, ensuring a tight connection between the water distribution plate and the body 110, and ensuring the sealing of the water distribution cavity 140. This allows water to be evenly sprayed out through the spray holes 121 of the water distribution plate 120 after the fluid delivery channel 130 distributes water and high-pressure gas to the water distribution cavity 140. In some embodiments, both the first magnetic attractor 125 and the second magnetic attractor 111 are magnets.

[0043] like Figure 9 and 10 As shown, the fluid transport channel 130 includes a transport section 131 and a spray section 132; the body 110 has a first surface 112 and a second surface 113 disposed opposite to each other; the transport section 131 is arranged along the first surface 112, the spray section 132 has a first end 1321 and a second end 1322, the first end 1321 of the spray section 132 is connected to the transport section 131, and the second end 1322 of the spray section 132 passes through the first surface 112 and the second surface 113 and extends into the water distribution chamber 140.

[0044] In this embodiment, the first surface 112 is the upper surface of the body 110, and the second surface 113 is the lower surface of the body 110. The first surface 112 and the second surface 113 are opposite to each other. The enclosure portion 123 of the water distribution plate 120 is tightly fitted with the second surface 113 of the body 110. Thus, the groove 124 of the water distribution plate 120 forms a sealed water distribution cavity 140 under the cover of the second surface 113. The tight fit between the enclosure portion 123 and the second surface 113 ensures the sealing of the water distribution cavity 140. One end of the conveying section 131 of the fluid conveying channel 130 is connected to the body 2000 of the coffee machine. Water or high-pressure gas is conveyed to the conveying section 131 by a water pump or an air pump. The first end 1321 of the spray section 132 is connected to the conveying section 131. The second end 1322 of the spray section 132 passes through the first surface 112 and the second surface 113 and extends into the water distribution chamber 140. The water or high-pressure gas conveyed to the conveying section 131 enters the spray section 132 and then enters the water distribution chamber 140 through the spray section 132, thus realizing the distribution of water or high-pressure gas to the water distribution chamber 140 through the fluid conveying channel 130.

[0045] like Figure 6 and 10 As shown, the second surface 113 is provided with an enclosure portion 1131, and the water distribution plate 120 is assembled inside the enclosure portion 1131 to form the water distribution cavity 140.

[0046] In this embodiment, the water distribution plate 120 is assembled inside the enclosure portion 1131 and forms a dense water distribution cavity 140 with the second surface 113. The enclosure portion 1131 facilitates the positioning and assembly of the water distribution plate 120, and the water distribution plate 120 also serves as a limit to prevent the water distribution plate 120 from shifting when using the shower head structure 100, thus affecting the spraying effect of the shower head structure 100.

[0047] like Figure 7 and 8 As shown, the second end 1322 of the spray section 132 is provided with an opening 1322a, and the water distribution plate 120 is provided with a receiving groove 126; the second end 1322 of the spray section 132 is located in the receiving groove 126, and the opening 1322a is configured to deliver water or high-pressure gas to the water distribution chamber 140.

[0048] In this embodiment, the opening 1322a of the second end 1322 of the spray section can be used to distribute water or high-pressure gas into the water distribution chamber 140. The second end 1322 of the spray section is located in the receiving groove 126 of the water distribution plate 120. On the one hand, it avoids the second end 1322 of the spray section from interfering with the water distribution plate 120 and prevents the second end 1322 of the spray section from pushing open the water distribution plate 120. On the other hand, the water flowing out of the opening 1322a first fills the receiving groove 126 and then slowly diffuses to the entire water distribution chamber 140 so that the water is evenly sprayed out from the water distribution plate 120 under the action of high-pressure gas. In some embodiments, the second end 1322 of the spray section is further provided with a piercing part 1322b, which is configured to pierce the coffee capsule. When it is necessary to brew the coffee capsule, the piercing part 1322b of the spray section can pierce the coffee capsule by removing the water distribution plate 120, and water and high-pressure gas can be distributed into the coffee capsule for extraction, thereby realizing the brewing of the coffee capsule.

[0049] like Figure 5 As shown, in some embodiments, the shower head structure 100 further includes an upper cover 150, which covers the first surface 112. The upper cover 150 and the body 110 can also be fixed together by fasteners such as bolts or clips, ensuring the integrity of the shower head structure 100.

[0050] To facilitate control of the coffee liquid extracted from the filter basket 200 flowing out of the fluid outlet 220, such as Figure 2 As shown in Figures 4 and 5, in some embodiments, the brewing system 1000 further includes a leak-proof valve 300, which is fitted to the fluid outlet 220 and configured to control the opening or closing of the fluid outlet 220. The leak-proof valve 300 is a valve structure used to control the opening or closing of the fluid outlet 220. When coffee is to be brewed, the leak-proof valve 300 opens the fluid outlet 220 to allow coffee to flow out; when coffee is not to be brewed, the leak-proof valve 300 closes the fluid outlet 220.

[0051] To ensure a more aesthetically pleasing brewing system, such as... Figure 1 and 2 As shown, the brewing system also includes a housing 400, and a filter basket 200 is assembled inside the housing 400, ensuring the aesthetics of the brewing system 1000.

[0052] Example 2: like Figure 12 As shown, this embodiment provides a coffee machine, including a body 2000 and a brewing system 1000 as described in Embodiment 1; the brewing system 1000 is mounted on the body 2000.

[0053] In this embodiment, the body 2000 can serve as the base for installation, providing support for the installation of the brewing system 1000 and ensuring the stability of the brewing system 1000 installation. Furthermore, the body 2000 provides the water and high-pressure gas required by the brewing system 1000 to achieve coffee brewing. During coffee brewing, coffee grounds are placed in the filter basket 200 of the brewing system 1000. In the first stage of the brewing system 1000, the body 2000 provides water to the brewing system 1000, which is distributed into the water distribution chamber 140 of the brewing system 1000. In the second stage, the body 2000 provides high-pressure gas to the brewing system 1000, so that the water in the water distribution chamber 140 is evenly sprayed onto the coffee grounds in the filter basket 200, thereby extracting the coffee. With the brewing system 1000 of Example 1, hot water can directly and evenly cover the coffee grounds, ensuring that each coffee particle is fully extracted, achieving a more uniform extraction effect and avoiding over-extraction or under-extraction of some coffee grounds, thereby improving the taste and quality of the coffee. Furthermore, since the hot water is sprayed directly onto the coffee grounds in the filter basket 200, heat loss during transmission is reduced, making the extraction process more efficient. Efficient extraction means that a larger quantity of coffee liquid can be produced in a shorter time, improving the extraction efficiency of the coffee machine and user satisfaction.
