Description

An easy-to-maintain rotating spout structure and coffee machine Technical Field

[0001] This invention relates to the field of coffee machine technology, and more specifically, to a maintenance-friendly rotating spout structure and a coffee machine. Background Technology

[0002] Currently, commercial coffee machines typically have cabinet doors to facilitate cleaning and maintenance of the brewing unit. To further facilitate this, the spout is usually installed in one of two ways. First, the spout and brewing unit are both located inside the cabinet. In this case, sufficient space is needed to allow for cleaning and maintenance without obstructing the spout, requiring a large cabinet and limiting its size. Second, the spout is placed on the cabinet door. While this arrangement ensures adequate space between the spout and brewing unit for cleaning and maintenance when the door is opened, each opening and closing of the door causes bending and stretching of the tubing connected to the spout, accelerating its aging. Furthermore, this arrangement increases the load on the door hinges, requiring higher-quality hinges and increasing the production and maintenance costs of the coffee machine.

[0003] Chinese patent CN104000497B discloses an installation structure for a coffee machine spout. It includes a spout housing mounted on the front panel of the coffee machine, with a coffee supply channel inside. The spout housing is constrained within a mounting housing, with the coffee supply channel protruding downwards from the mounting housing. A first through-hole corresponding to the coffee supply channel is formed on the front panel of the coffee machine. The mounting housing is connected to the front panel of the coffee machine via a rib groove and a snap-fit ​​structure. When the mounting housing is connected to the front panel of the coffee machine, the first through-hole allows the coffee supply channel to connect with the outlet of the brewing unit inside the coffee machine. To remove the spout, first detach the mounting housing containing the spout housing from the front panel of the coffee machine, then remove the spout housing from the mounting housing. The removal process is relatively convenient and facilitates cleaning of the removed spout.

[0004] The attached diagram of the aforementioned patent depicts a small home coffee machine. Typically, to reduce overall size and costs, the brewer in a home coffee machine cannot be removed for maintenance. However, the proposed detachable spout design offers the possibility of lowering the performance requirements of hinges on commercial coffee machine cabinets, optimizing cabinet dimensions, and preventing pipe bending during brewer assembly and disassembly. During installation, the connection between the fluid channel inside the spout and the corresponding connector inside the coffee machine cabinet is obscured by the cabinet and mounting casing, making direct observation impossible. Even if a connection problem occurs, it's difficult to pinpoint the cause, hindering repair and adjustment.

[0005] Based on the above reasons, the present invention aims to provide a maintenance-friendly rotating spout structure and coffee machine that is easy to maintain and allows for easy cleaning of the brewer, by optimizing the size of the coffee machine, simplifying the structure of the coffee machine, and reducing the risk of pipe breakage. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution: a maintenance-friendly rotating water nozzle structure, comprising a nozzle support, a lower nozzle cavity, a fluid connector, and a first hinge portion. The first hinge portion is connected to the nozzle support, and the hinge axis of the first hinge portion is vertical. The nozzle support is provided with an upper nozzle cavity, and the lower nozzle cavity is detachably connected to the nozzle support, forming a closed cavity. At least one fluid channel is provided inside the lower nozzle cavity, and at least one fluid outlet is provided at the bottom of each fluid channel. The upper nozzle cavity communicates with at least one fluid connector, and each fluid channel communicates with at least one fluid connector.

[0007] The present invention is further configured to include a fresh milk heating chamber, which is fixed in a closed cavity; the inlet of the fresh milk heating chamber is connected to a fluid connector for conveying fresh milk, and the outlet is connected to a fluid channel; there is also at least one fluid connector for conveying steam that is connected to the interior of the fresh milk heating chamber.

[0008] The invention is further configured such that at least one fluid connector for conveying steam injects steam into the milk heating chamber.

[0009] The present invention is further configured to include a temperature regulating switch, which is used to regulate the flow rate of fluid through the fresh milk heating chamber.

[0010] The invention is further configured to include a window cover plate, wherein an adjustment window for exposing a temperature adjustment switch is provided on the wall of the upper cavity of the nozzle, and the window cover plate is used to cover the adjustment window; the window cover plate is hinged to the nozzle support, and the window cover plate can be fixed at the adjustment window; or the window cover plate is detachably connected to the nozzle support.

[0011] The invention is further configured to include a spout sleeve, wherein all fluid connectors not connected to the fresh milk heating chamber are sealed to their corresponding fluid channels through the spout sleeve, and the liquid outlet of the fresh milk heating chamber is sealed to its corresponding fluid channel through the spout sleeve; the spout sleeve is provided with an exhaust channel, the bottom end of the exhaust channel is connected to the top of the defoaming channel, and the top end of the exhaust channel is connected to the upper cavity of the spout.

[0012] The present invention is further configured to include defoaming protrusions, at least one fluid channel is a defoaming channel, and at least one defoaming protrusion is fixed at each fluid outlet of all defoaming channels.

[0013] The present invention is further configured such that at least one lighting lamp is provided on the bottom surface of the spout support.

[0014] The invention is further configured to include a mounting cover plate, wherein the top surface of the outlet bracket has a mounting groove that surrounds the upper cavity of the outlet, and all lighting lamps pass through the bottom surface of the mounting groove from top to bottom. The mounting cover plate is used to seal the opening of the mounting groove, and it is detachably connected to the outlet bracket. The top of the upper cavity of the outlet passes through the mounting cover plate, and all fluid connectors are located above the mounting cover plate.

[0015] This invention also provides a coffee machine, comprising a cabinet, a front baffle assembly, a fluid supply assembly, and the aforementioned easy-to-maintain rotating spout structure. The fluid supply assembly is installed inside the cabinet and includes a brewer, which is detachably connected to the cabinet. Each fluid connector is detachably connected to a corresponding pipe of the fluid supply assembly. A maintenance port is provided on the cabinet, and the front baffle assembly is installed at the maintenance port. The rotating spout structure is hinged to the cabinet via a first hinge. When the front baffle assembly is open, the rotating spout structure can rotate away from the brewer around the hinge axis of the first hinge. When the front baffle assembly is closed, the rotating spout structure passes through the front baffle assembly, exposing all fluid outlets. At this time, the position of the rotating spout structure is fixed, and the maintenance port is blocked by the front baffle assembly and the rotating spout structure.

[0016] In summary, the present invention has the following advantages compared to the prior art:

[0017] In this invention, the rotating spout structure is hinged to the cabinet via the first hinge, so the front baffle assembly does not need to bear the full weight of the rotating spout structure for a long time, which helps to optimize the overall size of the coffee machine and improve the lifespan of the front baffle assembly.

[0018] Each fluid connector is detachably connected to the corresponding pipe of the fluid supply component, which effectively reduces the risk of pipe kinking. Furthermore, when connecting or disconnecting the fluid connector from the corresponding pipe of the fluid supply component, the operator's view will not be obstructed by the front baffle assembly.

[0034] Example

[0035] As shown in Figures 1-9, the present invention provides a maintenance-friendly rotating spout structure, comprising a spout support 11, a lower spout cavity 12, a fluid connector 13, and a first hinge portion 14. The first hinge portion 14 is connected to the spout support 11, and the hinge axis of the first hinge portion 14 is vertical. The spout support 11 is provided with an upper spout cavity 111, and the lower spout cavity 12 is detachably connected to the spout support 11, forming a closed cavity. At least one fluid channel 121 is provided inside the lower spout cavity 12, and each fluid channel 121 has at least one fluid outlet 122 at its bottom. The upper spout cavity 111 communicates with at least one fluid connector 13, and each fluid channel 121 communicates with at least one fluid connector 13.

[0036] Specifically, the fluid connector 13 is detachably connected to the outlet bracket 11. In this embodiment, the fluid connector 13 is mainly divided into two categories. One category is a steam connector; the other category is a liquid connector, which is used to transport liquid raw materials such as milk, coffee liquid, and hot chocolate liquid. There is at least one liquid outlet of the liquid connector directly above each fluid channel 121.

[0037] Specifically, the fluid channel 121 is provided with three channels. The first fluid channel is a single-line channel with a liquid outlet of a liquid connector located at the top of one end and a fluid outlet 122 located on the bottom surface of the other end. The second fluid channel is also a single-line channel with a fluid outlet 122 located on the bottom surface of each end, and the liquid outlet of the liquid connector is located above the center of the single-line channel. The third fluid channel is a multi-branch channel with multiple ends. Each end has a liquid outlet of a liquid connector located at the top or a fluid outlet 122 located on the bottom surface. In this embodiment, the multi-branch channel has four ends. There are two ends with liquid outlets of liquid connectors located at the top and two ends with fluid outlets 122 located on the bottom surface.

[0038] Specifically, the bottom surface of each fluid channel 121 is sloped, so that the height of the bottom surface of the fluid channel 121 gradually decreases as the distance from the fluid outlet 122 decreases, thereby reducing liquid residue in the fluid channel 121.

[0039] Specifically, this embodiment also includes a fresh milk heating chamber 8, which is fixed inside a closed cavity. The inlet of the fresh milk heating chamber 8 is connected to a liquid connector for conveying fresh milk, and the outlet is connected to a fluid channel 121. At least one steam connector is also connected to the interior of the fresh milk heating chamber 8 to heat the fluid inside. In this embodiment, the fresh milk heating chamber 8 is connected to a second fluid channel.

[0040] Specifically, at least one steam connector injects steam into the milk heating chamber 8, injecting high-pressure hot steam into the milk to form milk foam. In this embodiment, the milk heating chamber 8 is connected to two steam connectors, one for forming milk foam and the other for heating the milk or milk foam.

[0041] Specifically, this embodiment also includes a temperature regulating switch 9, which is used to regulate the flow rate of fluid through the fresh milk heating chamber 8, thereby adjusting the contact time between the fresh milk or milk foam and the steam, and thus achieving temperature regulation of the fresh milk or milk foam. The temperature regulating switch 9 can regulate the flow rate by controlling the cross-sectional area of ​​the liquid channel in the fresh milk heating chamber 8, similar to the principle of a valve, which is common knowledge and will not be elaborated here.

[0042] This embodiment also includes a window cover plate 16. An adjustment window 112 for exposing the temperature adjustment switch 9 is provided on the wall of the upper cavity 111 of the outlet. The window cover plate 16 covers the adjustment window 112, and closing the window cover plate 16 prevents accidental activation of the temperature adjustment switch 9. The window cover plate 16 can be hinged to the outlet bracket 11, and can also be fixed to the adjustment window 112; the window cover plate 16 can also be detachably connected to the outlet bracket 11. In this embodiment, the outlet bracket 11 has two slots 113, located on the left and right sides of the adjustment window 112 respectively. The two sides of the window cover plate 16 are inserted into the two slots 113 from top to bottom, and the bottom surface of the window cover plate 16 abuts against the outlet bracket 11. In this embodiment, the two slots 113 are integrally formed with the outlet bracket 11.

[0043] Specifically, the window cover 16 is provided with cantilever snap-fit ​​structures on both sides to abut against the two slots 113 respectively, reducing the possibility of the window cover 16 being opened accidentally.

[0044] Specifically, this embodiment also includes a spout sleeve 10. All fluid connectors 13 not connected to the fresh milk heating chamber 8 are sealed to their corresponding fluid channels 121 through the spout sleeve 10. The liquid outlet of the fresh milk heating chamber 8 is sealed to its corresponding fluid channel 121 through the spout sleeve 10 to reduce heat loss of the fluid in the fluid channel 121.

[0045] Specifically, in this embodiment, all fluid channels 121 are U-shaped, and the bottom surface of the nozzle sleeve 10 has protrusions that match the shape of all fluid channels 121. These protrusions are inserted into the corresponding fluid channels 121 and are sealed to all fluid channels 121. When it is necessary to clean the fluid channels 121, simply pull out the nozzle sleeve 10.

[0046] In this embodiment, the bottom surface of the spout sleeve 10 is also provided with an adjustment post 102. An adjustment post 102 is inserted into each fluid outlet 122 that is connected to the liquid outlet of the fresh milk heating chamber 8. The adjustment post 102 is provided with a protrusion, which cooperates with the inner wall of the fluid outlet 122 to control the size of the bubbles in the milk foam.

[0047] Specifically, this embodiment also includes defoaming protrusions 15. At least one fluid channel 121 serves as a defoaming channel, and at least one defoaming protrusion 15 is fixed at each fluid outlet 122 of all defoaming channels to break up air bubbles in the fluid. When multiple defoaming protrusions 15 are located at the same fluid outlet 122, it is optimal for all defoaming protrusions 15 to be evenly distributed along the edge of the fluid outlet 122. In this embodiment, a multi-branch channel is used as the defoaming channel, and four defoaming protrusions 15 are fixed at each fluid outlet 122.

[0048] Specifically, the nozzle sleeve 10 is provided with an exhaust channel 101. The bottom end of the exhaust channel 101 is connected to the top of the defoaming channel, and the top end of the exhaust channel 101 is connected to the upper cavity 111 of the nozzle, so as to facilitate the discharge of gas released by broken bubbles. In this embodiment, an exhaust channel 101 is provided above each fluid outlet 122 provided with a defoaming protrusion 15.

[0049] Specifically, the window cover 16 does not completely cover the adjustment window 112, so that the gas discharged from the exhaust channel 101 can be discharged into the upper cavity 111 of the mouthpiece through the adjustment window 112.

[0050] Specifically, at least one light 17 is provided on the bottom surface of the spout support 11. When using a container to receive liquid flowing from the fluid outlet 122, the light 17 can help the user confirm the liquid level in the container. In this embodiment, two lights 17 are provided, and the two lights 17 are respectively located on both sides of the upper cavity 111 of the spout.

[0051] This embodiment also includes a mounting cover plate 18. The top surface of the outlet bracket 11 has a mounting groove 114, which surrounds the upper cavity 111 of the outlet. All lighting lamps 17 pass through the bottom surface of the mounting groove 114 from top to bottom, and the wiring of the lighting lamps 17 is arranged within the mounting groove 114. The mounting cover plate 18 is used to seal the opening of the mounting groove 114 and is detachably connected to the outlet bracket 11. The top of the upper cavity 111 of the outlet passes through the mounting cover plate 18, and all fluid connectors 13 are located above the mounting cover plate 18. The mounting groove 114 not only effectively protects the wiring of the lighting lamps 17 but also forms a heat insulation layer and an anti-collision layer on the side of the upper cavity 111 of the outlet, helping to improve the heat insulation effect of the upper cavity 111 of the outlet and protecting the sidewalls of the upper cavity 111 of the outlet.

[0052] Specifically, a threaded connector 115 is provided in the mounting groove 114. Multiple bolts 19 pass through the mounting cover plate 18 and are threadedly connected to the threaded connector 115. Each bolt 19 is connected to one threaded connector 115. In this embodiment, three threaded connectors 115 are provided.

[0053] Specifically, each threaded connector 115 is provided with multiple reinforcing ribs 116 in the circumferential direction, and all reinforcing ribs 116 are fixedly connected to the inner wall of the mounting groove 114 to improve the strength of the threaded connector 115. In this embodiment, each threaded connector 115 is provided with four reinforcing ribs 116 in the axial direction.

[0054] Specifically, each threaded connector 115 is provided with two reinforcing ribs 116 on the side near the upper cavity 111 of the outlet and on the side away from the upper cavity 111 of the outlet, and both reinforcing ribs 116 are fixedly connected to the side wall of the mounting groove 114.

[0055] Specifically, a cantilever buckle 123 is provided on the side of the lower outlet cavity 12, and a stop 117 is provided on the side wall of the upper outlet cavity 111. The lower outlet cavity 12 is inserted into the upper outlet cavity 111 from the bottom, and the cantilever buckle 123 engages with the stop 117. In this embodiment, two cantilever buckles 123 are provided, located on the left and right sides of the lower outlet cavity, respectively, and each cantilever buckle 123 corresponds to one stop 117.

[0056] Specifically, the cantilever buckle 123 includes a locking part 1231 and a handle part 1232. The locking part 1231 is used to lock the stop 117. The handle part 1232 is located below the locking part 1231 and is always located below the outlet bracket 11, so as to control the locking and disengagement of the locking part 1231 and the stop 117.

[0057] As shown in Figures 10-11, this embodiment also provides a coffee machine, which includes a cabinet 2, a front baffle assembly, a fluid supply assembly, and the aforementioned easy-to-maintain rotating spout structure 1. The fluid supply assembly is installed inside the cabinet 2 and includes a brewer 3, which is detachably connected to the cabinet 2. Each fluid connector 13 is detachably connected to a corresponding pipe of the fluid supply assembly. A maintenance port is provided on the cabinet 2, and the front baffle assembly is installed at the maintenance port. The rotating spout structure 1 is hinged to the cabinet 2 via a first hinge 14. When the front baffle assembly is open, the connection between each fluid connector 13 and the corresponding pipe of the fluid supply assembly is disconnected, and the rotating spout structure 1 can rotate around the hinge axis of the first hinge 14 away from the brewer 3, thus meeting the space requirements for disassembling and assembling the brewer 3. When the front baffle assembly is closed, the rotating spout structure 1 passes through the front baffle assembly, exposing all fluid outlets 122. At this time, the position of the rotating spout structure 1 is fixed, and the maintenance port is blocked by the front baffle assembly and the rotating spout structure 1.

[0058] Specifically, the coffee machine also includes a hinge shaft 4 and a second hinge portion 21 fixed to the cabinet body 2; the hinge shaft 4 passes through the first hinge portion 14 and the second hinge portion 21, rotatably connecting the first hinge portion 14 and the second hinge portion 21; the hinge shaft 4 is detachably connected to both the first hinge portion 14 and the second hinge portion 21. In this embodiment, the first hinge portion 14 is integrally formed with the spout bracket 11, and the second hinge portion 21 is integrally formed with the cabinet body 2.

[0059] Specifically, multiple first hinge portions 14 and multiple second hinge portions 21 are provided, with all first hinge portions 14 and all second hinge portions 21 longitudinally overlapping each other. In this embodiment, two first hinge portions 14 and three second hinge portions 21 are provided.

[0060] Specifically, the hinge shaft 4 has a stop at its top and a thread at its bottom. A nut is provided below the lowest second hinge part 21, and the hinge shaft 4 is threadedly connected to the nut. The hinge shaft 4 is rotatably connected to the other second hinge parts 21 and all first hinge parts 14.

[0061] The aforementioned easy-to-maintain rotating spout structure 1 is hinged to the cabinet 2, eliminating the need for the front baffle assembly to bear the entire weight of the rotating spout structure 1 for extended periods, thus extending its service life. Simultaneously, this embodiment increases the distance between the brewer 3 and the rotating spout structure 1 through rotation, reducing the need for ample space in the cabinet 2 for brewer 3 assembly and disassembly, thereby optimizing the overall size of the coffee machine. Furthermore, in this embodiment, the fluid connectors 13 are detachably connected to the corresponding pipes of the fluid supply assembly, effectively reducing the risk of pipe kinking and contributing to extended pipe life. Since the rotating spout structure 1 and the front baffle assembly are not directly connected in this embodiment, the operator's view is not obstructed by the front baffle assembly when connecting or disconnecting the fluid connectors 13 from the corresponding pipes of the fluid supply assembly.

[0062] The front baffle assembly consists of an upper baffle assembly 51 and a lower baffle assembly 52. ​​The upper baffle assembly 51 is hinged to the cabinet 2 to facilitate the maintenance and replacement of the fluid connector 13. In this embodiment, the bottom surface of the upper baffle assembly 51 is flush with the top surface of the mounting cover plate 18. The lower baffle assembly 52 is detachably connected to the cabinet 2. The bottom surface and left and right sides of the outlet bracket 11 are in contact with the lower baffle assembly 52, so that the lower baffle assembly 52 can limit the position of the rotating water outlet structure 1 and also provide auxiliary support for the rotating water outlet structure 1, reducing the wear of the first hinge part 14, the second hinge part 21 and the hinge shaft 4.

[0063] Specifically, the lower baffle assembly 52 is fixedly connected to other components inside the coffee machine to form a drawer-type structure. While these components enter and exit the maintenance port, the lower baffle assembly 52 can be connected and separated from the cabinet 2. The structure is simple and helps to further optimize the cabinet size.

[0064] Specifically, the lower baffle assembly 52 is provided with a handle 521.

[0065] Specifically, the lower baffle assembly 52 is divided into multiple parts, each of which forms a drawer-type structure with different components inside the coffee machine that are not connected to each other, and each part is provided with a handle 521. In this embodiment, the lower baffle assembly 52 is divided into two parts, which form a drawer-type structure with the waste bin 6 and the water tank 7 inside the coffee machine, respectively.

[0066] Specifically, the brewer 3 has a drawer-type structure, and the brewer 3 enters and exits the maintenance port along a horizontal straight line, making it easy to disassemble and assemble.

[0067] In summary, in this embodiment, the rotating spout structure 1 is hinged to the cabinet 2 via the first hinge 14. The front baffle assembly does not need to bear the full weight of the rotating spout structure 1 for extended periods, which helps optimize the overall size of the coffee machine and improves the lifespan of the front baffle assembly. Each fluid connector 13 is detachably connected to the corresponding pipe of the fluid supply assembly, effectively reducing the risk of pipe kinking. Furthermore, when connecting or disconnecting the fluid connector 13 from the corresponding pipe of the fluid supply assembly, the operator's view is not obstructed by the front baffle assembly.

[0068] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
