Technical Field

[0001] This utility model relates to coffee beverage making equipment, specifically a coffee machine that avoids waste liquid overflow. Background Technology

[0002] Fully automatic coffee machines are becoming increasingly popular in the market because they integrate functions such as automatic bean grinding, brewing, and grounds removal. Patent document CN115363422A discloses a coffee machine brewing unit and brewing method involving such a machine. Users simply place their cup on the beverage outlet and press a button to obtain a delicious cup of coffee. However, due to the wide range of cup heights used by users, even with an adjustable beverage outlet, some taller cups cannot be placed in the water return tank below the outlet to receive the coffee.

[0003] The current solution to this problem is to make the water return box and the sludge return box detachable. However, when the water return box is removed and the product is used, the liquid that was originally drained from inside the product will be discharged onto the table or even overflow into the product, causing safety issues. Utility Model Content

[0004] This invention addresses the safety issue of existing technologies where waste liquid discharged from the product after removing the water return box can spill onto the table or even overflow into the product itself. It provides a coffee machine that prevents waste liquid overflow, aiming to recycle waste liquid generated during the coffee-making process regardless of whether the water return box is removed, thus preventing spillage onto the table or even into the product.

[0005] To achieve the above objectives, the present invention provides a coffee machine that avoids waste liquid overflow. The machine includes a body with a waste liquid outlet inside and a beverage outlet outside. Below the waste liquid outlet is a guide channel for receiving waste liquid and a first liquid accumulation area located below the guide channel. The guide channel has a flow port. Below the beverage outlet is a second liquid accumulation box that can be detached from the machine body. The second liquid accumulation box has a second liquid accumulation area. The second liquid accumulation area overlaps with the first liquid accumulation area below the flow port, and the second liquid accumulation area is located above the first liquid accumulation area. When the second liquid accumulation box is in the installed position, the second liquid accumulation area is located below the flow port to receive waste liquid from the flow port. When the second liquid accumulation box is removed, the first liquid accumulation area is located below the flow port to receive waste liquid from the flow port.

[0006] When this coffee machine makes coffee beverages, if the cup used to receive the beverage is not too tall, it can be placed in the second collection box to receive the beverage. The waste liquid discharged from the waste liquid outlet is guided by the guide channel and then collected in the second collection area and the second collection box. If the cup used to receive the beverage is too tall, the second collection box can be removed from the machine body, and the cup can be placed on the table where the coffee machine is located to receive the beverage. The waste liquid discharged from the waste liquid outlet is guided by the guide channel and then collected in the first collection area. Regardless of whether the return water box is removed, the waste liquid generated during the coffee making process can be recycled, preventing waste liquid from being discharged onto the table or even overflowing into the product, ensuring table cleanliness and product safety.

[0007] Preferably, the coffee machine includes a brewing unit disposed within the machine body, a coffee grounds container and a first liquid collection container disposed below the brewing unit, and the brewing unit has a pressure relief channel, with a waste liquid outlet being the outer port of the pressure relief channel. Accordingly, the first liquid collection container is used to collect waste liquid within the machine body, and the pressure relief channel and waste liquid outlet are used to discharge waste liquid discharged during the operation of the brewing unit.

[0008] Preferably, the first liquid accumulation area is located within the first liquid accumulation box. This simplifies the structure and facilitates installation within or removal from the machine body.

The second liquid collection area is connected to or independently separated from the second liquid collection box. When connected, the capacity to hold waste liquid can be increased; when independently configured, the structure can be strengthened through independent areas.

[0013] Preferably, the waste liquid outlet is connected to a drain outlet via a pipe, and the drain outlet is located above the guide channel. This guides the waste liquid discharged from the waste liquid outlet to the drain outlet, shortening the path of the waste liquid discharged from the waste liquid outlet into the guide channel.

[0014] Preferably, the volume of the second liquid collection box is larger than that of the first liquid collection box and the guide channel. This allows the second liquid collection box to hold more liquid and is easier to clean.

[0015] Preferably, the second liquid collection box is located on the front side of the machine body, and its bottom surface is on the same plane as the bottom surface of the machine body. Accordingly, when the second liquid collection box is removed from the machine body, the space below the beverage outlet can be made up to the maximum extent for placing extra-tall cups.

[0016] Preferably, to facilitate removal of the second liquid collection box from the machine body, the second liquid collection box is inserted into the first liquid collection box. Specifically, the side wall of the first liquid collection area has a notch, and the second liquid collection area is inserted into the notch. The second liquid collection box can be inserted into or removed from the machine body by pulling it out, making the operation convenient.

[0017] This invention features a guide channel for receiving waste liquid below the waste liquid outlet and a first liquid collection area below the guide channel. The guide channel has a guide opening. A second liquid collection box, detachable from the main body, is located below the beverage outlet. The second liquid collection box has a second liquid collection area that overlaps with the first liquid collection area below the guide opening and is positioned above the first liquid collection area. When the second liquid collection box is in the installed position, the second liquid collection area is below the guide opening to receive waste liquid from the guide opening. When the second liquid collection box is removed, the first liquid collection area is below the guide opening to receive waste liquid from the guide opening. When making coffee beverages, if the cup used to receive the coffee beverage is not too tall, the cup can be placed in the second liquid collection box to receive the coffee beverage. The waste liquid discharged from the waste liquid outlet is guided by the guide opening of the guide channel and then received by the second liquid collection box. If the cup used to receive coffee beverages is too tall, the second liquid collection box can be removed separately from the machine body. The cup can be placed on the table where the coffee machine is located to receive coffee beverages. The waste liquid discharged from the waste liquid outlet is guided by the guide port of the guide channel and then received by the first liquid collection area. Regardless of whether the return water box is removed, the waste liquid during the coffee making process can be recycled, preventing the waste liquid from being discharged onto the table or even overflowing into the product.

[0022] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0023] Figure 1-5 A coffee machine capable of recycling all waste liquid is shown, comprising a body 100, a waste liquid outlet 401 inside the body 100, and a beverage outlet 101 outside the body 101. Below the waste liquid outlet 401 is a guide channel 530 for receiving waste liquid and a first liquid collection area 511 located below the guide channel 530. The guide channel 530 has a guide opening 531. Below the beverage outlet 101 is a second liquid collection box 540 that can be separately removed from the body. The second liquid collection box 540 has a second liquid collection area 541, which overlaps with the first liquid collection area 511 below the guide port 531 and is located above the first liquid collection area 511. When the second liquid collection box 540 is in the installed position, the second liquid collection area 541 is located below the guide port 531 to receive waste liquid from the guide port. When the second liquid collection box 540 is removed, the first liquid collection area 511 is located below the guide port 531 to receive waste liquid from the guide port. The beverage outlet 101 is used to discharge liquid coffee beverage. The waste liquid outlet is used to discharge generated waste liquid.

[0024] When this coffee machine makes coffee beverages, if the cup used to receive the beverage is not too tall, it can be placed in the second collection box to receive the beverage. The waste liquid discharged from the waste liquid outlet is guided by the guide channel and then collected in the second collection area and the second collection box. If the cup used to receive the beverage is too tall, the second collection box can be removed from the machine body, and the cup can be placed on the table where the coffee machine is located to receive the beverage. The waste liquid discharged from the waste liquid outlet is guided by the guide channel and then collected in the first collection area. Regardless of whether the return water box is removed, the waste liquid generated during the coffee making process can be recycled, preventing waste liquid from being discharged onto the table or even overflowing into the product, ensuring table cleanliness and product safety.

[0025] After receiving coffee in a cup, it is inevitable that some liquid will drip from the spout, or waste liquid will be collected after rinsing the cup.

[0026] The above structure embodies the basic concept of this utility model, enabling the realization of its technical solution. To further improve the clamping and positioning device, the following preferred technical means can be used to obtain a better embodiment based on the above structure.

[0027] like Figure 3-5 As shown, the coffee machine includes a brewing unit 400 disposed within the machine body 100. A coffee grounds container 520 and a first liquid collection container 510 are disposed below the brewing unit 400. The brewing unit 400 has a pressure relief channel 411, and a waste liquid outlet 401 is the external port of the pressure relief channel 411. Accordingly, the first liquid collection container 510 is used to collect waste liquid within the machine body, and the pressure relief channel 411 and the waste liquid outlet 401 are used to discharge waste liquid discharged during the operation of the brewing unit.

[0028] like Figure 9-12 As shown, the brewing unit 400 includes a brewing plug assembly 410 and a brewing chamber assembly 420. (As indicated...) Figure 9 As shown, when coffee powder is filled into the chamber 421 of the brewing chamber assembly, the brewing plug assembly 410 can be moved into the chamber 421 to compact the coffee powder. Figure 10 The image shows the state of the coffee grounds compacted by the brewing stopper assembly 410. During the compaction process, to balance the pressure, such as... Figure 9 , Figure 10 The pressure relief channel 411, which is configured in the brewing plug assembly 410, is opened to allow air to be discharged from the waste liquid outlet 401 from the chamber 421. Figure 11 In the indicated state, the pressure relief channel 411 is closed, and water is supplied to the chamber 421 through the water channel 412 configured in the brewing stopper assembly 410. The water flows through the compacted coffee grounds to obtain a coffee beverage, which is then discharged into the cup from the beverage outlet 101. Once brewing is complete, the water supply is stopped, and the coffee grounds become coffee grounds. The brewing stopper assembly 410 then... Figure 12 As shown, the pressure relief channel 411 opens to balance the air pressure between chamber 421 and the outside, allowing the brewing stopper assembly 410 to reset smoothly. After the brewing stopper assembly 410 is completely withdrawn from chamber 421, the coffee grounds are pushed upwards from the chamber by the lifting member 422 and further pushed down into the coffee grounds container 520 during the movement of the brewing chamber assembly. Repeat. Figure 9-12During continuous brewing, waste liquid containing coffee beverage, water, coffee powder, etc., will flow out from waste liquid outlet 401. Therefore, the waste liquid needs to be collected to prevent overflow onto the table. The opening and closing of the pressure relief channel 411 is achieved by the movement of the valve stem 413 relative to the valve port 414. When the valve stem 413 moves away from the valve port 414, the pressure relief channel 411 is opened; when the valve stem 413 blocks the valve port 414, the pressure relief channel 411 is closed. The movement of the valve stem 413 is driven by the motor 415.

[0029] In addition, when the brewing unit is working, condensation will form due to temperature changes caused by the input of hot water, and water that is diverted here to clean up scattered coffee grounds also needs to be collected to prevent it from flowing onto the table.

[0030] like Figure 5-8 As shown, the first liquid accumulation area 511 is constructed within the first liquid accumulation box 510. This simplifies the structure and facilitates installation within or removal from the machine body.

[0031] like Figure 3-4 As shown, the machine body 100 is equipped with a water supply system and a grinder 300. The grinder 300 grinds coffee beans into coffee powder and delivers it to the brewing unit 400. The water supply system supplies water to the brewing unit to brew the coffee powder into a coffee beverage. This achieves automatic coffee brewing. Specifically, the water supply system includes a water tank 210, a water pump 220, and a heater. The water pump 220 delivers water from the water tank 210 to the brewing unit 400. As the water flows through the heater, it can be heated to a suitable temperature as needed. The delivered water brews the coffee powder in the brewing unit 400 into a coffee beverage, which is then discharged from the beverage outlet 101. A cup can be placed below the beverage outlet 101 to receive the coffee beverage.

[0032] Based on the above structure, the first liquid collection box 510 is used to collect condensate from the brewing unit or water flowing into the brewing unit. The coffee grounds box 520 is used to collect coffee grounds. The second liquid collection box 540 is used to collect coffee beverage dripping from the beverage outlet 101 and waste liquid after rinsing the cup.

[0033] like Figure 6-8 As shown, the first liquid collection box 510, the coffee grounds box 520, and the guide channel 530 are either integrated as a single unit or assembled separately. Integrating them as a single unit prevents the loss of individual parts, while assembling them separately facilitates disassembly and cleaning.

[0034] like Figure 5 As shown, the first liquid collection box 510, coffee grounds box 520, flow channel 530, and second liquid collection box 540 are configured to be detached from the machine body together. This allows for removal from the machine body to empty the waste liquid and to clean the first liquid collection box, coffee grounds box, flow channel, and second liquid collection box.

[0035] The first liquid accumulation area 511 is connected to or independently separated from the first liquid accumulation box 510. The second liquid accumulation area 541 is connected to or independently separated from the second liquid accumulation box 540. When connected, the capacity to hold waste liquid can be increased; when independently configured, the structure can be strengthened through independent areas.

[0036] like Figure 3-4 As shown, waste liquid outlet 401 is connected to drain outlet 102 via a pipe, and drain outlet 102 is located above guide channel 530. This guides the waste liquid discharged from the waste liquid outlet to the drain outlet, shortening the path of the waste liquid from the waste liquid outlet into the guide channel. Figure 3-4 In the diagram, dashed lines represent the path of waste liquid outlet drainage.

[0037] Preferably, the volume of the second liquid collection box 540 is larger than that of the first liquid collection box and the guide channel. This allows the second liquid collection box to hold more liquid and is easier to clean.

[0038] like Figure 1 , Figure 3 As shown, the second liquid collection box 540 is located on the front side of the body 100, and its bottom surface is on the same plane as the bottom surface of the body. Accordingly, when the second liquid collection box is removed from the body, the space below the beverage outlet can be made up to the maximum extent for placing extra-tall cups.

[0039] like Figure 8 As shown, to facilitate removal of the second liquid collection box from the machine body, the second liquid collection box 540 is inserted into the first liquid collection box 510. Specifically, the side wall of the first liquid collection area 511 has a notch 512, and the second liquid collection area 541 is inserted into the notch 512. The second liquid collection box can be inserted into or removed from the machine body by pulling it out, making the operation convenient.
