DETAILED DESCRIPTION

[0048] Various aspects and features of the present application are described herein with reference to the accompanying drawings.

[0049] It should be understood that various modifications may be made to the embodiments of the present application. Therefore, the above description should not be considered as limiting, but only as an example of an embodiment. Other modifications within the scope and spirit of the present application will occur to those skilled in the art.

[0050] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the present application and, together with the general description of the present application given above and the detailed description of the embodiments given below, serve to explain the principles of the present application.

[0051] These and other characteristics of the present application will become apparent from the following description of a preferred form of embodiment given as a non-limiting example with reference to the accompanying drawings.

[0052] It should also be understood that although the present application has been described with reference to some specific examples, those skilled in the art will be able to readily implement many other equivalent forms of the present application.

[0053] The above and other aspects, features and advantages of the present application will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.

[0054] Specific embodiments of the present application are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present application, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present application. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as a basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any suitable detailed structure.

[0055] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0056] To solve the problems in the background technology, the present application provides a coffee machine, such as Figure 1 , Figure 2 and Figure 3 As shown, the coffee machine includes a main frame 10, a funnel assembly, a driving assembly, a cleaning assembly, a slag receiving assembly 17 and a water tank 9.

[0057] The main frame 10 serves as a base for installing or placing other structural parts. The main frame 10 can be in the form of a shell formed by enclosing plastic sheets. The main frame 10 has a brewing position and a washing position.

[0058] The funnel assembly is arranged at the brewing position of the main frame 10, and the funnel assembly includes a funnel 5 and a filter 4 arranged in the funnel 5, and the filter 4 is hinged to the main frame 10. When it is necessary to brew coffee, the filter 4 is located in the funnel 5, and coffee powder can be placed in the filter 4. Water is poured into the funnel assembly to brew the coffee powder in the filter 4 to form coffee liquid, and the coffee liquid drips from the opening at the bottom of the funnel 5 into the coffee pot 11 placed below the funnel assembly. When the coffee is brewed, if the filter 4 needs to be cleaned, the filter 4 can be turned out from the funnel 5 and turned to the cleaning position.

[0059] like Figure 2 As shown, when the filter screen 4 is located in the funnel 5, the upper end of the filter screen 4 is open, as shown in FIG. Figure 5As shown, when the filter screen 4 is turned over to the cleaning position, the downward end of the filter screen 4 is open, so that the coffee grounds in the filter screen 4 can fall naturally from the open end. On the other hand, when the cleaning component flushes the filter screen 4, the coffee grounds that fail to fall naturally can be flushed away by the flushing action of the cleaning component, and then fall from the open end into the ground receiving component 17. This prevents the coffee grounds from accumulating at the bottom of the filter screen 4 and failing to be cleaned quickly and thoroughly when the filter screen 4 is cleaned with the open end of the filter screen 4 facing upward.

[0060] The driving assembly is connected to the filter 4, and is used to drive the filter 4 to flip from the funnel 5 to the cleaning position, thereby realizing the automatic flipping of the filter 4, without the need to manually remove the filter 4 or the funnel assembly from the coffee machine for cleaning. This improves the cleaning efficiency of the filter 4, and also prevents coffee grounds and residual coffee from dripping onto the operator or onto other locations when the filter 4 or the funnel assembly is manually removed from the coffee machine.

[0061] The cleaning component is arranged on the main frame 10 and is located above the cleaning position. The cleaning component is used to clean the filter screen 4 flipped to the cleaning position. The cleaning component is located above the cleaning position. When the filter screen 4 flips to the cleaning position, the cleaning component can be started to spray water downward. The water sprayed by the cleaning component can rinse the filter screen 4 located below it. At this time, the downward end of the filter screen 4 is open. Under the impact of the water flow, the coffee grounds and the residual coffee liquid on the filter screen 4 will be rinsed away, and the mixture of coffee grounds and water produced during the rinsing process will naturally fall downward along the filter screen 4 into the residue receiving component 17.

[0062] The above-mentioned residue receiving assembly 17 is arranged below the cleaning position, and is used to receive the mixture of coffee residues and water produced by flushing the filter screen 4. The residue receiving assembly 17 receives the mixture of coffee residues and water produced by flushing the filter screen 4, and can be subsequently processed in a centralized manner, such as dumping it into a trash can or a sewer.

[0063] The water tank 9 can be arranged on the main frame 10 or placed separately. The water tank 9 is connected to the cleaning assembly and is used to supply water to the cleaning assembly so that the cleaning assembly can rinse the filter screen 4 at the cleaning position through the water flow.

[0064] After the filter screen 4 is automatically flipped to the cleaning position by the driving component in the embodiment of the utility model, the filter screen 4 is rinsed from the top of the filter screen 4 by the cleaning component to more thoroughly rinse out the coffee residues remaining in the filter screen 4; at the same time, the filter screen 4 is automatically discharged by the automatic flipping, and the filter screen 4 is automatically cleaned in cooperation with the cleaning component, so that the coffee machine can continuously make coffee, improve the coffee making efficiency, and improve the user experience. The mixture of coffee residues and water produced by flushing the filter screen 4 is received by the residue receiving component 17, and then the mixture of coffee residues and water is processed.

[0065] In some embodiments, in combination Figure 1 The filter screen 4 is provided with a hinge shaft 41.

[0066] When the filter 4 is in the brewing position, the end of the filter facing upward is an open end, so that when brewing coffee, the brewed coffee liquid can enter the funnel 5 through the filter, and drip from the opening at the bottom of the funnel 5 along the inner wall of the funnel 5 into the coffee pot 11 below. At this time, the end of the filter facing upward is an open end, and when brewing coffee, the water flow can brew the coffee powder in the filter in a larger range, so that the coffee powder can be brewed more thoroughly.

[0067] The filter is hinged to the main frame 10 via a hinge shaft 41, and the hinge shaft 41 is also connected to a driving assembly, which can drive the filter to flip 180° around the axis of the hinge shaft 41 to the cleaning position, so that the filter is in a state with the open end facing downward, thereby realizing the dumping of coffee grounds in the filter and facilitating the cleaning assembly to flush the filter.

[0068] Specifically, the middle part of the hinge shaft 41 is connected to the filter, and the two ends of the hinge shaft 41 are respectively matched with the intersection holes on the main frame 10, and one end of the hinge shaft 41 is also connected to the driving assembly. Alternatively, the hinge shaft 41 includes a rotating shaft and an auxiliary shaft, wherein the rotating shaft and the auxiliary shaft are coaxially arranged on the filter. One end of the rotating shaft is fixed to the filter, and the other end thereof is hinged to the main frame 10, and the end of the rotating shaft hinged to the main frame 10 is also connected to the driving assembly; one end of the auxiliary shaft is connected to the filter, and the other end of the auxiliary shaft is hinged to the main frame 10. When the driving assembly drives the rotating shaft to rotate, the filter and the auxiliary shaft are driven to rotate.

[0069] The filter screen 4 is turned 180° to the cleaning position, with the open end of the filter screen 4 facing downward, so that the coffee grounds in the filter screen 4 can be more easily washed away, thereby improving the washing effect of the filter screen 4.

[0070] In some embodiments, in combination Figure 3 , the driving assembly includes a motor 14, a driving gear 15 and a driven gear 16. The motor 14 can be arranged on the main frame 10, the driving gear 15 is arranged on the output shaft of the motor 14, the driving gear 15 is meshed with the driven gear 16, and the driven gear 16 is arranged at one end of the hinge shaft 41. One end of the hinge shaft 41 passes through the center of the driven gear 16 and is hinged to the main frame 10. Of course, it can be understood that the driving assembly can also adopt other structural forms, as long as it can achieve connection with the hinge shaft 41 and drive the hinge shaft 41 to rotate. This is only used as an example and does not constitute a limitation on the scope of protection of the claims.

[0071] The driving assembly composed of the motor 14 and the gear combination is connected to the hinge shaft 41, and drives the hinge shaft 41 and the filter screen 4 to rotate, thereby realizing automatic flipping of the filter screen 4 and avoiding the trouble of manually taking out the filter screen 4 for cleaning.

[0072] In some embodiments, the coffee machine also provides water to the cleaning component through a water channel structure. Specifically, Figure 8 The cleaning assembly includes a cleaning nozzle 3 and a first water supply pipe.

[0073] The cleaning nozzle 3 is arranged on the main frame 10, and the cleaning nozzle 3 is located above the cleaning position, and the water outlet of the cleaning nozzle 3 is downward. The cleaning nozzle 3 is connected to one end of the first water supply pipe, and the other end of the first water supply pipe is connected to the water tank 9. When the filter 4 is turned over to the cleaning position, the cleaning nozzle 3 can spray water to the outer surface of the filter 4. Because the water flow has a certain impact force on the outer surface of the filter 4, the coffee grounds in the mesh of the filter 4 can be washed away while washing the outer surface of the filter 4. At the same time, the inner surface of the filter 4 can also be cleaned. The coffee grounds on the filter 4 are washed and dropped into the residue receiving assembly 17. The filter 4 located in the cleaning position is washed from above the filter 4 by the cleaning nozzle 3, which improves the cleaning effect of the filter 4.

[0074] In some embodiments, the cleaning component further includes a water pump 6, the water inlet of the water pump 6 is connected to the water tank 9, and the water outlet of the water pump is connected to the other end of the first water supply pipe. The water pump is used to pump the water in the water tank 9 to the first water supply pipe, and then the first water supply pipe delivers the water to the cleaning nozzle 3, and then the water is sprayed to the filter 4 located at the cleaning position through the downward water outlet of the cleaning nozzle 3 to clean the filter 4. The water pump can pump the water in the water tank 9 to the first water supply pipe and the cleaning nozzle 3 at a relatively high pressure, so that the cleaning nozzle 3 can flush the filter 4 with a certain pressure of water flow, thereby improving the cleaning effect of the filter 4.

[0075] In some embodiments, in combination Figure 6 and Figure 7 The slag receiving assembly 17 includes a wastewater box 172 and a slag receiving box 171 .

[0076] The residue receiving box 171 is arranged in the waste water box 172, and the top of the residue receiving box 171 is open. The residue receiving box 171 is provided with a filter mesh hole, so that the water in the coffee residue falling into the residue receiving box 171 can enter the waste water box 172 through the filter mesh hole. The coffee residue is received by the residue receiving box 171, and the water in the residue receiving box 171 enters the waste water box 172 through the filter mesh hole, so that the coffee residue and the waste water are separated, and the pipe is prevented from being blocked when the mixture of the coffee residue and the water is cleaned.

[0077] In some embodiments, the Figure 7The residue box 171 is provided with a handle 173, which is hinged to the residue box 171. The residue box 171 can be lifted from the waste water box 172 by pulling the handle 173, so as to separate the coffee residue from the waste water, that is, to achieve simple dry and wet separation, which is convenient for cleaning and maintenance.

[0078] In some embodiments, in combination Figure 1 and Figure 2 The coffee machine further includes a base 12, which is disposed at the bottom of the main frame 10, and a slag receiving assembly 17 is placed on the base 12. A space for placing the slag receiving assembly 17 can be formed between the base 12 and the main frame 10, and the slag receiving assembly 17 can be placed on the base 12 during the process of receiving coffee slag, so as to avoid the slag receiving assembly 17 being exposed. In addition, the base 12 can also be used to place the coffee pot 11.

[0079] In some embodiments, in combination Figure 8 The coffee machine further comprises a front cover plate 1, a brewing water spout 2, a flow meter 7, a three-way pipe 18, a three-way valve 19, a safety valve 20 and a second water supply pipeline. The coffee machine also supplies water to the brewing water spout 2 through a water channel structure.

[0080] The front cover 1 is arranged at the front side of the main frame 10, and the brewing position and the cleaning position can be arranged at the front side and the rear side of the main frame 10 respectively. In addition, a grinder assembly 8 can be arranged on the main frame 10 for grinding coffee beans. The grinder assembly 8 is located above the brewing position, so that the ground coffee powder can fall directly into the funnel assembly.

[0081] The brewing spout 2 is arranged on the front cover plate 1, and the brewing spout 2 is located above the brewing position. The brewing spout 2 is used to provide brewing water into the funnel assembly to brew the coffee powder in the funnel assembly. The water outlet of the water pump 6 is connected to the first pipe mouth of the three-way pipe 18, and the second pipe mouth of the three-way pipe 18 is connected to the safety valve 20. The safety valve 20 is used to discharge the water in the water pump in an emergency. The third pipe mouth of the three-way pipe 18 is connected to the first pipe mouth of the three-way valve 19, the second pipe mouth of the three-way valve 19 is connected to one end of the first water supply pipeline, the third pipe mouth of the three-way valve 19 is connected to one end of the second water supply pipeline, and the other end of the second water supply pipeline is connected to the brewing spout 2 to transport the water in the water tank 9 to the brewing spout 2. The flow meter 7 is arranged on the second water supply pipeline to measure the amount of water provided to the brewing spout 2 through the second water supply pipeline. The second water supply pipe provides water for brewing coffee to the brewing water nozzle 2, and the water supply is measured by the flow meter 7, so that coffee with better taste can be brewed with a suitable amount of water at the brewing position.

[0082] Of course, the second water supply pipeline may also be connected to another water tank 9 instead of sharing the same water tank 9 with the first water supply pipeline.

[0083] In some embodiments, the coffee machine further includes a heater 13, which is disposed on a pipe between the three-way pipe 18 and the three-way valve 19. The heater 13 is used to heat water from the water tank 9 so that the second water supply pipe delivers heated water to the brewing nozzle 2 and the first water supply pipe delivers heated water to the cleaning nozzle 3. The heater 13 can be disposed on the base 12 or on the main frame 10. The heater 13 delivers heated water to the brewing nozzle 2 through the second water supply pipe so that the coffee machine can brew hot coffee; in addition, the filter is cleaned with hot water to improve the cleaning effect.

[0084] When dripping coffee, the three-way valve 19 is powered off, and the water pump 6 pumps water through the heater 13, the first pipe opening of the three-way valve 19 and the third pipe opening of the three-way valve 19 to spray onto the coffee powder in the filter 4, and the drip-filtered coffee is discharged into the coffee pot 11 below; after the coffee dripping is completed, the motor drives the filter 4 to rotate 180° to the cleaning position for cleaning, and the three-way valve 19 is powered on, and the water pump 6 pumps water through the heater 13, the first pipe opening of the three-way valve 19 and the second pipe opening of the three-way valve 19 to spray onto the inverted filter 4, so as to rinse the filter 4 from the outside to the inside.
