Description

Technical Field

[0001] This invention relates to a coffee machine and its brewing mechanism, and is a multi-functional coffee machine. Background Technology

[0002] A coffee machine is an electrical appliance used for making coffee. They are generally divided into semi-automatic and fully automatic types. Semi-automatic coffee machines require manual operation for grinding, tamping, filling, brewing, and removing grounds. Fully automatic coffee machines are fully automated, controlling the entire coffee brewing process from preheating and cleaning to grinding, tamping, brewing, and dispensing. They brew coffee according to scientific data and procedures, requiring only the touch of a button. However, with the improvement of people's living standards and the popularization of coffee culture, the functional demands of coffee machines are becoming increasingly diverse and demanding. Traditional coffee machines often have limited functions, only supporting drip brewing or using only specific types of coffee capsules, failing to meet consumers' needs for different coffee brewing methods in different scenarios. For example, drip coffee machines are relatively simple to use, but the coffee flavor may be somewhat limited; capsule coffee machines are convenient, but the types of capsules are limited and the cost is high; extraction coffee machines can produce richer coffee, but the operation is relatively complex; and for consumers who prefer cappuccinos, lattes, and other milk-based coffees, additional equipment is needed to make milk foam. Major coffee capsule brands include: Nestlé's Nespresso, JDE's TASSIMO and K-cup, Italian brands Oro, Lavazza, Monodol, Gaggia's ecaffe, and Korean brand Allcream. Therefore, the market urgently needs a coffee machine that integrates multiple functions to improve user experience and convenience. Examples include Chinese patent application number 202320768185.5, authorized on June 23, 2023, entitled "A Coffee Machine"; and Chinese patent application number 202222338445.3, authorized on March 3, 2023, entitled "A Dual-Purpose Coffee Machine and Top Cover Assembly." However, these coffee machines and similar products are primarily drip coffee machines, making them difficult to use as capsule coffee machines, especially for simultaneous use with K-cup coffee capsules and other coffee capsules. Summary of the Invention

[0003] To overcome the above shortcomings, the purpose of this invention is to provide a multi-functional coffee machine with integrated functions, thereby solving the technical problems of inconvenient switching between drip and capsule modes in existing similar products, particularly the difficulty in simultaneous use with K-cup coffee capsules, and the relatively limited functional modes. This objective is achieved through the following technical solution.

[0004] A multi-functional coffee machine includes a drip pot, a milk carton assembly, a funnel assembly, a water tank assembly, and a brewing assembly. One side of the machine's outlet has a drip capsule brewing outlet, and the other side has an extraction capsule brewing outlet. The machine contains a control system and a hot water system. The boiler, valve body, and pump body of the hot water system are connected to the control system and the corresponding outlets via pipes. A brewing assembly cover is located on one side of the top of the machine. The brewing assembly is situated within the machine body below the cover. The brewing assembly cover contains a hot water channel. The cover is hinged to the outer surface of the coffee basket opening at the top of the brewing assembly via a pivot on one side. The key structural design features a filter basket or K-cup capsule holder within the coffee basket of the brewing assembly. A water-blocking device is located at the bottom of the coffee basket. A central through-hole at the bottom of the coffee basket connects to the groove of the water-blocking seat of the device via a raised channel on one side. The outer end of the raised channel at the bottom of the coffee basket aligns with the water-blocking silicone in the groove of the water-blocking seat below. One end of the groove of the water-blocking seat has a water outlet hole. The middle of the water-blocking seat is hinged to a raised hinge post at the bottom of the coffee basket. A water-blocking spring is located in the groove at the other end of the water-blocking seat, or a torsion spring is located at the hinge. The bottom of the water-blocking seat at the water-blocking spring protrudes above the water-blocking silicone. At the bottom of the sealing seat at one end, when the drip pot is placed into the machine, the lid of the drip pot pushes the bottom of the sealing seat at the sealing spring upward, simultaneously causing the other end of the sealing seat to tilt downward and open the seal between the sealing silicone and the end through hole. When the drip pot is removed from the machine, the sealing seat returns to its original position through the sealing spring or torsion spring, and the seal between the sealing silicone and the end through hole is restored. The bottom of the K-cup capsule holder is equipped with a K-cup capsule coffee piercing needle and a capsule water outlet. The brewing assembly cover above the K-cup capsule holder has a K-cup capsule water inlet piercing needle in the middle. Thus, the brewing assembly includes an American drip function module and an American K-cup function module. The extraction capsule brewing outlet and funnel assembly are combined to form an espresso extraction function module. At the same time, the coffee machine has hot water and milk frothing functions, and has five major functions: drip, K-cup, espresso extraction module, hot water function, and milk frothing function. Based on the above structural features, the milk carton assembly and funnel assembly, as well as the extraction capsule brewing outlet on the corresponding side of the machine body and the cover of the storage tray below, can also be omitted, and the coffee machine can be used as an all-in-one coffee machine that combines drip and K-cup functions.

[0005] The top opening of the K-cup capsule holder is fixed to the top opening of the coffee basket via a skirt. The K-cup capsule is placed inside the downward-protruding capsule cavity of the K-cup capsule holder. The coffee-dispensing piercing needle of the K-cup capsule is located on one side of the bottom of the capsule cavity inside the K-cup capsule holder. The bottom of the K-cup capsule holder has a connecting funnel that fits into the bottom of the holder. One side of the bottom of the connecting funnel has a protruding channel cavity that fits into the protruding channel at the bottom of the coffee basket. The opening of the channel cavity of the connecting funnel is provided with silicone for connecting the funnel. The capsule outlet includes a through hole on one side of the bottom of the K-cup capsule holder at the location of the coffee-dispensing piercing needle, a central hollow through hole, and a side through hole symmetrical to the through hole on the other side of the K-cup capsule at the location of the coffee-dispensing piercing needle. In the above structure, the silicone for connecting the funnel and the protruding channel at the bottom of the coffee basket cooperate to form a sealed channel.

[0006] When the top opening of the K-cup capsule holder is fastened to the top opening of the coffee basket via a skirt, the lower edge of one side of the skirt abuts against one end of the guide rod in the guide rod groove on the outer diameter side of the coffee basket, pushing the guide rod downward. This causes the other end of the guide rod to simultaneously swing downward at the connection point of the water-blocking silicone part of the water-blocking seat, opening the sealing joint between the water-blocking silicone and the end through hole. Therefore, it eliminates the need to open the water-blocking device by pushing it open with a cup such as a drip coffee maker; the water-blocking device automatically opens after the K-cup capsule holder is placed in the coffee basket, further facilitating the use of mugs and other cups besides drip coffee makers, and allowing for direct use of mugs and other cups.

[0007] The K-cup capsule holder has a second sensing magnet on one side of the outer diameter skirt. When the K-cup capsule holder is placed in the coffee basket, the second sensing magnet is aligned with the second Hall switch assembly fixedly installed on one side of the outer diameter of the coffee basket.

[0008] The end of the water-blocking seat above the water outlet is connected to one end of the guide rod. The guide rod is set in the guide rod groove on one side of the outer diameter of the coffee basket. The guide rod is equipped with a first sensing magnet. The first sensing magnet is aligned with the first Hall switch assembly fixedly set on one side of the outer diameter of the coffee basket. The other end of the guide rod is fitted into the limiting sleeve in the guide groove.

[0009] A safety switch assembly is provided on one side of the outer plane of the top opening of the coffee basket below the top cover of the brewing unit. When the top cover of the brewing unit is closed, the safety switch assembly is activated.

[0010] The hot water channel of the brewing assembly includes a drip hot water channel and a central hot water channel. A water inlet seat is provided within the cavity formed by the brewing top cover and the brewing bottom cover of the brewing assembly. The bottom opening of the water inlet seat is sealed and connected to the brewing bottom cover to form a water outlet ring cavity. A sealing rod is provided outside the K-cup capsule water inlet puncture needle in the middle of the brewing assembly top cover. The water outlet ring cavity communicates with the water inlet hole of one side of the water inlet seat through the sealing rod, forming the drip hot water channel. The K-cup capsule water inlet puncture needle communicates with the water inlet hole of one side of the water inlet seat through a seal, forming the central hot water channel. When the K-cup capsule holder is placed in the coffee basket, the ring at the top of the K-cup capsule holder abuts against the sealing rod, sealing the drip hot water channel. A rod spring is provided at the sealing rod within the drip hot water channel. When the K-cup capsule holder is removed and the filter basket is placed in the coffee basket, the sealing rod is reset by the rod spring, opening the drip hot water channel.

[0011] The top of the machine body is provided with a storage tray cover on the other side, and a storage slot is provided on the top of the machine body below the storage tray cover, in which a powder scoop and a powder bowl are placed.
