Description

Technical Field

[0001] This utility model belongs to the field of coffee machine technology, and specifically provides a coffee machine. Background Technology

[0002] As people's living standards improve, coffee machines are becoming increasingly popular in daily life. Traditional coffee machines typically consist of a coffee grinder, a brewer, and a feed chute connecting the two. The coffee grinder grinds coffee beans into powder, which is then conveyed through the feed chute to the brewer for brewing.

[0003] In existing coffee machine structures, the relatively narrow internal space of the feed channel, along with potential corners and uneven areas, makes it easy for coffee grounds to adhere to the inner walls. Furthermore, the feed channel is typically difficult to clean. This is partly because cleaning tools struggle to reach every nook and cranny of the channel, and partly because frequent disassembly for cleaning is not only cumbersome but can also damage machine components and shorten its lifespan.

[0004] Over time, the residual coffee powder in the feed channel will breed a large number of bacteria, which will not only affect the hygiene of the coffee machine, but also affect the taste of the brewed coffee, causing the coffee to lose its original flavor and fail to meet consumers' demand for high-quality coffee. Utility Model Content

[0005] One objective of this invention is to solve the problem that existing coffee machines are prone to bacterial growth due to the difficulty in cleaning the feed channel, which affects the taste of the coffee.

[0006] To achieve the above objectives, this utility model provides a coffee machine, comprising:

[0007] A coffee grinder is used to grind coffee beans into coffee powder.

[0008] A brewer for receiving coffee powder from the coffee grinder and brewing the coffee powder;

[0009] The conveyor is connected at one end to the coffee grinder and at the other end to the brewer. The conveyor is inclined downward from the coffee grinder to the brewer so that the coffee powder in the coffee grinder enters the brewer through the conveyor under the action of gravity.

[0010] A blower is configured to blow any remaining coffee powder in the feed channel into the brewer.

[0011] Optionally, the length of the feed channel between the blower and the coffee grinder is less than the length of the feed channel between the blower and the brewer.

[0012] Optionally, the blower is located on the top side of the conveying channel to prevent the coffee powder from entering the blower.

[0013] Optionally, the conveying channel is provided with an air inlet aligned with the blower, and the inside of the conveying channel is provided with a baffle plate aligned with the air inlet. The baffle plate is used to direct the air flowing into the conveying channel toward the brewer.

[0014] Optionally, the wind deflector is tilted downwards towards the direction of the brewer.

[0015] Optionally, the baffle plate is fixedly connected to or integrally formed with the top wall of the conveying channel.

[0016] Optionally, the baffle extends to the two sidewalls of the conveyor that are connected to the top wall.

[0017] Optionally, the fan is an axial flow fan.

[0018] Optionally, the coffee machine further includes a vibration generator mounted on the feed channel to shake off the coffee powder adhering to the inner wall of the feed channel.

[0019] Optionally, the vibration generator is a vibration motor.

[0020] Based on the foregoing description, those skilled in the art will understand that in the aforementioned technical solution of this utility model, by configuring a fan to blow the residual coffee powder in the conveying channel into the brewer, the amount of residual coffee powder in the conveying channel is reduced, thereby effectively preventing the growth of bacteria and ensuring the taste of the coffee.

[0021] Furthermore, by installing a baffle plate inside the conveying channel that is aligned with the air inlet, the air flowing into the conveying channel can be directed towards the brewer while reducing wind resistance and ensuring the stability of the airflow.

[0022] Furthermore, by installing a vibration generator on the conveying channel, the coffee powder adhering to the inner wall of the conveying channel is shaken off, so that the shaken-off coffee powder can be blown into the brewer by the action of the fan, thereby improving the cleanliness of the conveying channel.

[0023] Other beneficial effects of this utility model will be described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand the improvement purpose, features and advantages of this utility model. Attached Figure Description

[0037] like Figure 1 As shown, in some embodiments of this utility model, the coffee machine 001 includes a coffee grinder 100, a brewer 200, a feed channel 300, and a blower 400.

[0038] The coffee grinder 100 is used to grind coffee beans into coffee powder.

[0039] The brewer 200 is used to receive coffee powder from the coffee grinder 100 and brew the coffee powder.

[0040] One end of the conveying channel 300 is connected to the coffee grinder 100, and the other end of the conveying channel 300 is connected to the brewer 200. The conveying channel 300 is inclined downward from the coffee grinder 100 to the brewer 200 so that the coffee powder in the coffee grinder 100 enters the brewer 200 through the conveying channel 300 under the action of gravity.

[0041] The blower 400 is configured to blow the remaining coffee powder in the conveyor 300 into the brewer 200.

[0042] Those skilled in the art will understand that by configuring the blower 400 to blow the residual coffee powder in the conveying channel 300 into the brewer 200, the amount of residual coffee powder in the conveying channel 300 is reduced, thereby effectively preventing the growth of bacteria and ensuring the taste of the coffee.

[0043] Although not shown in the figure, in this invention, the coffee grinder 100 may include a container, as well as a grinding mechanism and a motor mounted on the container.

[0044] The container is equipped with an inlet and an outlet. The inlet is used to introduce coffee beans into the grinding mechanism; the outlet is connected to the conveyor channel 300 and is used to discharge the ground coffee powder.

[0045] In this process, the grinding mechanism directly contacts and grinds the coffee beans into coffee powder. The grinding mechanism can be a blade-type grinding mechanism, a toothed disc-type grinding mechanism, a conical burr grinding mechanism, or any other feasible grinding mechanism.

[0046] In this invention, the blade-type grinding mechanism mainly consists of one or more high-speed rotating blades. During operation, the blades rotate at high speed under the drive of a motor, chopping and grinding the coffee beans.

[0047] In this invention, the toothed grinding mechanism consists of two parallel metal discs with special tooth patterns; one disc is fixed, while the other rotates under the drive of a motor. Coffee beans are fed from above and are gradually ground into powder as they pass through the gaps between the toothed discs.

[0048] In this invention, the conical grinding mechanism consists of a conical inner blade and a matching outer blade, and the coffee beans are ground in the spiral channel between the inner and outer blades.

[0049] The motor is used to drive the grinding mechanism to grind coffee beans.

[0050] Furthermore, the coffee grinder 100 with a toothed disc grinding mechanism may also include a grinding adjustment device for adjusting the distance between the two toothed discs, thereby controlling the coarseness of the coffee powder.

[0051] In this invention, the coffee grinder 100 breaks coffee beans into fine particles through mechanical force. For blade-type grinders, high-speed rotating blades cut and crush the coffee beans; for toothed disc grinders, the squeezing, shearing, and friction between the toothed discs gradually grind the coffee beans into powder. During the grinding process, the cell structure of the coffee beans is broken down, releasing internal flavor compounds and laying the foundation for brewing delicious coffee.

[0052] Furthermore, although not shown in the figures, in this invention, the brewer 200 may include a filter, and coffee grounds may be located above the filter. After hot water enters the brewer 200, it mixes thoroughly with the coffee grounds above the filter and then flows out through the filter.

[0053] Furthermore, the length of the conveying channel 300 between the blower 400 and the coffee grinder 100 is less than the length of the conveying channel 300 between the blower 400 and the brewer 200, so that the coffee powder attached in the conveying channel 300 can be blown toward the brewer 200 as much as possible.

[0054] Specifically, those skilled in the art can, as needed, place the blower 400 at one end of the conveying channel 300 near the coffee grinder 100 so that all the coffee powder adhering in the conveying channel 300 can be blown toward the brewer 200.

[0055] like Figure 1 As shown, the blower 400 is located on the top side of the conveying channel 300 to prevent coffee powder from entering the blower 400.

[0056] In this utility model, the fan 400 can be an axial flow fan 400.

[0057] Of course, those skilled in the art can also configure the fan 400 as a mixed-flow fan or a centrifugal fan as needed.

[0058] It should be noted that the coffee of this invention is not only applicable to coffee, but also to any other feasible solid brewing beverages, such as soybeans, rice, mung beans, tea, etc.

[0059] It should also be noted that, although Figure 1 Only the coffee grinder 100, brewer 200, feed duct 300, and blower 400 are shown in the figure, but the coffee machine 001 also includes the body, casing, control panel, and other structures. Since the structures not shown in the figure are well known to those skilled in the art, they will not be described in detail here.

[0060] The following reference Figure 2 The coffee machine 001 in some other embodiments of the present invention will be described in detail below.

[0061] It should be noted before proceeding that, for ease of description and to enable those skilled in the art to quickly understand the technical solution of this utility model, the following description will only detail the differences between some embodiments and some embodiments described above. For the similarities between some embodiments and some embodiments described above, those skilled in the art can refer to the descriptions in some embodiments described above.

[0062] like Figure 2 As shown, in some other embodiments of this utility model, the material conveying channel 300 is provided with an air inlet 301 aligned with the blower 400.

[0063] Furthermore, the inside of the conveying channel 300 is provided with a baffle plate 310 aligned with the air inlet 301. The baffle plate 310 is used to direct the air flowing into the conveying channel 300 toward the brewer 200.

[0064] Those skilled in the art will understand that by providing a baffle plate 310 inside the conveying channel 300 that is aligned with the air inlet 301, the air flowing into the conveying channel 300 can be directed toward the brewer 200 while reducing wind resistance and ensuring the stability of the airflow.

[0065] from Figure 2 As can be seen, the wind deflector 310 is tilted downwards towards the direction of the brewer 200 to smoothly change the airflow direction and avoid wind noise.

[0066] Furthermore, although not shown in the figure, in some other embodiments of this utility model, the wind baffle 310 is fixedly connected to or integrally formed with the top wall of the conveying channel 300.

[0067] Fixed connections can include welding, bonding, snap-fitting, screw connections, etc.

[0068] Furthermore, in some other embodiments of this utility model, the baffle plate 310 extends to the two side walls of the conveying channel 300 that are connected to the top wall. That is, the top wall and the left and right side walls of the conveying channel 300 are respectively connected to the baffle plate 310, so that the baffle plate 310 improves the structural strength of the conveying channel 300. At the same time, the area on the top side of the baffle plate 310 is made as flat as possible to avoid the baffle plate 310 affecting the movement of coffee powder in the conveying channel 300 due to the bottom side being too low.

[0069] like Figure 2 As shown, in some other embodiments of the present invention, the coffee machine 001 further includes a vibration generator 500 installed on the conveying channel 300 to shake off the coffee powder adhering to the inner wall of the conveying channel 300.

[0070] Those skilled in the art will understand that by installing a vibration generator 500 on the conveying channel 300 to shake off the coffee powder adhering to the inner wall of the conveying channel 300, the shaken-off coffee powder can be blown into the brewer 200 by the blower 400, thereby improving the cleanliness of the conveying channel 300.

[0071] Specifically, after coffee machine 001 is used, the vibration generator 500 is first activated for a period of time (e.g., 30 seconds, 1 minute, 3 minutes, 5 minutes, etc.) to shake off the coffee powder adhering to the inner wall of the feed channel 300. Then, the blower 400 is activated, causing the shaken-off coffee powder to be blown into the brewer 200. This improves the cleanliness of the feed channel 300 compared to simply cleaning the coffee powder with the blower 400. Finally, the brewer 200 is removed and cleaned.

[0072] In some other embodiments of this utility model, the vibration generator 500 may be a vibration motor.

[0073] Of course, in other embodiments of this utility model, those skilled in the art can also, as needed, set the vibration generator 500 as an ultrasonic generator, an electromagnetic vibrator, a piezoelectric vibrator, or any other feasible vibrator.

[0074] The technical solution of this utility model has been described in conjunction with several embodiments above. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is not limited to these specific embodiments. Without departing from the technical principles of this utility model, those skilled in the art can disassemble and combine the technical solutions in the above embodiments, and can also make equivalent changes or substitutions to the relevant technical features. Any changes, equivalent substitutions, improvements, etc., made within the technical concept and / or technical principles of this utility model will fall within the protection scope of this utility model.

[0075] Finally, it should be noted that in this invention, the term "connection" refers to fluid communication, allowing fluid (e.g., air, liquid) to flow between two interconnected entities. Furthermore, this "connection" can be either a leak-free flow of fluid between two interconnected entities, or a flow with slight leakage between two interconnected entities.
