Description

Technical Field

[0001] This utility model belongs to the field of coffee machine technology, and in particular relates to a brewer and a coffee machine. Background Technology

[0002] In existing coffee makers, after brewing, the coffee grounds in the brewing cup are pushed to the rim of the cup by a pusher rod, where they are scraped off by a scraper. For example, Chinese Patent CN120078264A discloses a brewing device for beverage preparation equipment. After brewing, a pusher rod inside the brewing cup moves upwards, pushing the resulting coffee grounds to the top opening of the cup, where a pusher mechanism then removes them. However, after scraping off the grounds, coffee grounds easily remain on the filter assembly at the top of the pusher rod, affecting the cleanliness and taste of subsequent brews. Furthermore, if these residues are not removed promptly, they can accumulate and breed bacteria or clog the channels. Utility Model Content

[0003] In view of the above-mentioned problems existing in the prior art, the purpose of this utility model embodiment is to provide a brewer and a coffee machine.

[0004] The technical solution adopted in this embodiment of the utility model is: A brewing device, comprising: Brewing stand; A brewing cup is mounted on the brewing stand; A filter assembly is movably disposed inside the brewing cup to receive coffee powder, and the filter assembly can be moved to the rim of the brewing cup; The cleaning assembly includes a jet pipe and an air supply component. The jet pipe is mounted on the brewing stand, and the air supply component is connected to the jet pipe for injecting gas into the jet pipe. The gas ejected from the jet pipe can remove residual powder residue from the filter assembly at the mouth of the cup.

[0005] In some embodiments, the brewer further includes a scraper plate disposed on a brewing stand, the brewing cup having a powder discharge position on the brewing stand, the brewing cup being movable relative to the brewing stand, and during the movement of the powder discharge position, the scraper plate being able to scrape off powder residue from the filter assembly, and the jet pipe being located on the side of the brewing cup at the powder discharge position. In some embodiments, the jet pipe is a straight pipe, the axis of the brewing cup is perpendicular to the axis of the jet pipe, and a plurality of jet holes are spaced apart on the jet pipe.

[0006] In some embodiments, the jet pipe is an arc-shaped pipe with an arc radius equal to that of the filter assembly, and multiple jet holes are spaced apart on the jet pipe. The arc-shaped jet pipe can better conform to the arc radius of the filter assembly, and the high-pressure gas ejected from the multiple spaced jet holes on the jet pipe can act more precisely and comprehensively on the surface of the filter assembly, efficiently removing residual powder and sludge, and further improving the cleaning effect.

[0007] In some embodiments, the brewing cup has a powder and residue channel, and the scraper can scrape the powder and residue from the filter assembly into the powder and residue channel; The cleaning assembly also includes a jet nozzle, and the air supply component is connected to the jet nozzle. When the brewing cup is in the powder discharge position, the gas ejected by the jet nozzle can remove residue located on the surface of the powder slurry. Therefore, this brewer can not only clean powder residue on the surface of the filter assembly, but also clean powder residue on the surface of the powder slurry.

[0008] In some embodiments, the jet nozzle is fixed to the brewing stand and positioned above the brewing cup; When the air outlet of the jet nozzle faces downwards and the brewing cup is in the powder discharge position, the air outlet of the jet nozzle is opposite to the surface of the powder residue slide.

[0009] In some embodiments, the number of air nozzles is multiple, and the multiple air nozzles are spaced apart on the brewing stand.

[0010] In some embodiments, the brewing support includes a first side plate and a second side plate spaced apart, defining a cup cavity for placing a brewing cup between the first side plate and the second side plate; the jet pipe is fixed to one of the first side plate and the second side plate, or fixed between the first side plate and the second side plate.

[0011] In some embodiments, the air supply component is an air pump, and the air supply component is connected to the air nozzle and the air pipe respectively through the air passage. The air passage is provided with a solenoid valve for controlling the on and off states.

[0012] A coffee machine comprising the brewer described in any of the above embodiments.

[0013] Compared with the prior art, the beneficial effects of the embodiments of this utility model are as follows: The cleaning device in this embodiment injects high-pressure gas into the jet pipe. This gas is then ejected at high speed from the jet nozzle on the jet pipe, forming a strong airflow that directly acts on the powder residue on the filter assembly, quickly blowing it away from the filter. This ensures the cleanliness of the filter assembly and provides favorable conditions for the next brewing process. This automatic cleaning method not only improves cleaning efficiency but also avoids the inconvenience and hygiene problems that may arise from manual cleaning, enhancing the overall user experience of the coffee machine.

[0020] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0021] like Figure 1 and Figure 2 As shown in the figure, this application provides a brewing device, which may include a brewing support 1, a brewing cup 2, a filter assembly 3, and a cleaning assembly 4.

[0022] The brewing cup 2 is set on the brewing stand 1. The brewing cup 2 is used to hold coffee powder, and hot water is poured into the brewing cup 2 to brew coffee.

[0023] The filter assembly 3 is movably positioned inside the brewing cup 2 to receive coffee grounds placed inside. The filter assembly 3 can move relative to the brewing cup 2, moving between the bottom and the rim. For example, when the filter assembly 3 is at the bottom, coffee grounds can be poured into the cup, forming coffee grounds after brewing. At this point, the filter assembly 3 can move to the rim of the brewing cup 2 to deliver the coffee grounds into the rim, facilitating subsequent grounds removal.

[0024] The cleaning assembly 4 includes a jet pipe 8 and an air supply component 41. The jet pipe 8 is mounted on the brewing stand 1. The air supply component 41 can be connected to the jet pipe 8 to inject gas into the jet pipe 8. The gas ejected from the jet pipe 8 can remove residual powder residue from the filter assembly 3 at the mouth of the cup.

[0025] The brewer in this embodiment, by incorporating a cleaning component 4, automatically cleans residual coffee powder from the filter assembly 3 after the brewing process. Specifically, high-pressure gas is injected into the jet pipe 8, and this gas is ejected at high speed from the jet nozzle 81 on the jet pipe 8, forming a strong airflow that directly acts on the coffee powder on the filter assembly 3, quickly blowing it away from the filter. This ensures the cleanliness of the filter assembly 3 and provides favorable conditions for the next brewing process. This automatic cleaning method not only improves cleaning efficiency but also avoids the inconvenience and hygiene problems that may arise from manual cleaning, enhancing the overall user experience of the coffee machine.

[0026] like Figure 1 and Figure 2 As shown, in some embodiments, the brewing cup 2 can move relative to the brewing support 1 and has at least a grounds discharge position on the brewing support 1. The grounds discharge position can be understood as follows: after the coffee powder in the brewing cup 2 has been brewed, the filter assembly 3 can move to a position near the rim of the cup, thereby pushing the coffee grounds it has collected to the rim of the cup, and then move to a specific position for grounds discharge, which is the grounds discharge position.

[0027] In this embodiment, the brewing cup 2 can be slidably connected to the brewing support 1. For example, the brewing support 1 may have a track groove, and the brewing cup 2 may be disposed on a guide post extending into the track groove. The brewing cup 2 can move along the track groove to achieve movement relative to the brewing support 1. As for the power to move the brewing cup 2, it can be achieved by a corresponding drive structure or manually, and this embodiment does not make specific limitations.

[0028] In this embodiment, the brewer may also include a powder scraper 7. The powder scraper 7 may be disposed on the brewing support 1. During the process of the brewing cup 2 moving to the slag discharge position, the powder scraper 7 may first scrape off the powder residue on the filter screen assembly 3. After the brewing cup 2 moves to the slag discharge position, high-pressure gas is introduced into the jet pipe 8 to remove the powder residue remaining on the filter screen assembly 3.

[0029] The jet pipe 8 can be positioned on the side of the brewing cup 2 where the powder is being discharged. After the powder scraper 7 scrapes off the powder residue, high-pressure gas can be injected into the jet pipe 8 immediately to remove any remaining powder residue on the surface.

[0030] like Figure 1 and Figure 2As shown, in some embodiments, the filter assembly 3 may include a filter element 31 and a powder pusher 32. The filter element 31 is located inside the brewing cup 2 and is used to receive coffee powder. The outer periphery of the filter element 31 is fitted with a sealing ring, and the filter element 31 can be fitted to the inner wall of the brewing cup 2 through the sealing ring.

[0031] The bottom of the brewing cup 2 has a through hole through which the coffee grounds pusher 32 extends into the cup body and connects to the filter 31. The up and down movement of the pusher 32 can drive the filter 31 to move synchronously. When the pusher 32 moves upward, it can deliver the coffee grounds on the filter 31 to the rim of the cup.

[0032] like Figure 4 , Figure 5 and Figure 7 As shown, in some embodiments, the shape of the jet pipe 8 can be a straight pipe, and the length of the jet pipe 8 is at least greater than or equal to the outer diameter of the brewing cup 2.

[0033] The axis of the brewing cup 2 is perpendicular to the axis of the jet pipe 8. Multiple jet holes 81 are spaced apart along the length of the jet pipe 8. The high-pressure gas entering and exiting the jet pipe 8 from the gas supply component 41 can be discharged from multiple jet holes 81 at the same time and blown together onto the surface of the filter assembly 3.

[0034] The design of multiple jet holes 81 makes the airflow distribution more uniform, fully covering the surface of the filter assembly 3 and ensuring that residual powder is thoroughly removed. At the same time, this design also improves cleaning efficiency and reduces the time required for cleaning.

[0035] Alternatively, in other embodiments, the jet pipe 8 may also be an arc-shaped pipe with an arc length equal to that of the filter assembly 3, and a plurality of jet holes 81 are provided at intervals along the arc direction on the jet pipe 8.

[0036] The opening direction of the arc-shaped jet pipe 8 can be consistent with the moving direction of the brewing cup 2. When the brewing cup 2 moves to the powder receiving position, the arc-shaped jet pipe 8 can better fit the curvature of the filter assembly 3. The high-pressure gas ejected from the multiple jet holes 81 spaced apart on the jet pipe 8 can act more accurately and comprehensively on the surface of the filter assembly 3, efficiently removing residual powder residue and further improving the cleaning effect.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the brewing cup 2 may have a powder sludge channel 21, and the powder scraper 7 can scrape the powder sludge on the filter assembly 3 into the powder sludge channel 21, and let it fall into the powder receiving cup or other container for powder sludge through the powder sludge channel 21.

[0038] The cleaning assembly 4 in this embodiment may further include a jet nozzle 6. The air supply component 41 may also be connected to the jet nozzle 6. The high-pressure gas output by the air supply component 41 can be ejected not only through the jet pipe 8 but also through the jet nozzle 6.

[0039] When the brewing cup 2 is in the powder discharge position, the gas ejected from the nozzle 6 can blow towards the surface of the powder residue chute 21, thereby blowing away the residue left on the surface of the powder residue chute 21. Therefore, the brewer of this embodiment can not only clean the powder residue on the surface of the filter assembly 3, but also clean the powder residue on the surface of the powder residue chute 21.

[0040] like Figures 1 to 4 As shown, in some embodiments, the nozzle 6 can be fixed to the brewing holder 1 and located above the brewing cup 2.

[0041] When the brewing cup 2 is in the powder discharge position, the air outlet 81 of the air nozzle 6 faces downward. When the brewing cup 2 is in the powder discharge position, the air outlet 81 of the air nozzle 6 is opposite to the surface of the powder residue chute 21. At this time, the high-pressure gas sprayed downward by the air nozzle 6 can directly act on the surface of the powder residue chute 21, which can effectively peel off the powder residue that is stuck due to moisture, so that the powder residue can fall smoothly into the powder receiving cup below the powder residue chute 21.

[0042] In some embodiments, there can be multiple air nozzles 6, which are spaced apart on the brewing support 1. By blowing air simultaneously through multiple air nozzles 6, a wider area of ​​the powder sludge chute 21 can be covered, which is especially suitable for powder sludge chute 21 with curved structures or complex surfaces. Each air nozzle 6 can work independently or collaboratively, and the airflow intensity and coverage can be adjusted according to actual cleaning needs to further enhance the cleaning effect.

[0043] In some embodiments, multiple air nozzles 6 may be spaced apart in the extending direction of the powder sludge chute 21, thereby increasing the cleaning range of the powder sludge chute 21.

[0044] like Figure 1 and Figure 2 As shown, in some embodiments, the brewer may also include a brewing head 5, which may be located above the brewing cup 2. When coffee powder is poured into the brewing cup 2, the brewing cup 2 may move relative to the brewing support 1 so that the brewing head 5 moves into the brewing cup 2 to squeeze the coffee powder and brew it.

[0045] Furthermore, when the brewing cup 2 is moved to the powder discharge position, the powder and residue slide 21 on the brewing cup 2 can be located below the brewing head 5, and multiple air nozzles 6 can be arranged around the brewing head 5. The high-pressure gas sprayed by the multiple air nozzles 6 can also clean the powder or coffee powder on the surface of the brewing head 5.

[0046] like Figure 3 , Figure 4, Figure 5 and Figure 6 As shown, in some embodiments, the shape of the nozzle 6 can be constructed as a tube structure with both ends open. The brewing support 1 can be provided with a fixed channel for placing the nozzle 6. The inlet end of the fixed channel can be opposite to the outside, and the outlet end of the fixed channel can be opposite to the powder and slag chute 21. The nozzle 6 can be inserted into the inlet end of the fixed channel and fixed by a corresponding pressure plate 13, etc.

[0047] In some embodiments, the brewing support 1 may include a first side plate 11 and a second side plate 12 spaced apart, and the first side plate 11 and the second side plate 12 may define a cup cavity for placing the brewing cup 2.

[0048] The brewing cup 2 can move within the cup cavity. The jet pipe 8 can be fixed to one of the first side plate 11 and the second side plate 12, or fixed between the first side plate 11 and the second side plate 12.

[0049] For example, when the jet pipe 8 is fixed to the two side plates, the first side plate 11 and the second side plate 12 may have corresponding through holes, and the jet pipe 8 is respectively inserted into the through holes of the first side plate 11 and the second side plate 12.

[0050] When the jet pipe 8 is fixed to one of the side plates, a clip for fixing the jet pipe 8 can be provided on the side plate to fix the jet pipe 8 to the side plate.

[0051] In some embodiments, the air supply component 41 can be an air pump, and the air supply component 41 can be connected to the jet nozzle 6 and the jet pipe 8 respectively through the air passage 43. The air passage 43 can be equipped with a solenoid valve 42, which can control the opening and closing of the air passage 43.

[0052] This utility model embodiment also provides a coffee machine, which may include the brewer described in any of the above embodiments.

[0053] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
