Description

Technical Field

[0001] This application relates to the field of coffee machine technology, and particularly to a coffee machine. Background Technology

[0002] As coffee machines become increasingly feature-rich, including functions like cold brew, ice making, and direct water dispensing, the number of internal components inevitably increases, leading to larger overall dimensions and making it difficult to meet the demands of miniaturization.

The raw water tank is connected to the water inlet of the filter assembly. The orthographic projections of the refrigerator, the filter assembly, and the raw water tank in a direction perpendicular to the front panel are all located within the orthographic projection range of the front panel.

[0006] In some embodiments, the dimension of the refrigerator along the front-rear direction of the front panel is defined as L, and the dimension of the refrigerator along the left-right direction of the front panel is defined as W, satisfying L > W.

[0007] In some embodiments, the refrigerator has an ice storage cavity and a cold water cavity that are connected to each other, with the ice storage cavity located above the cold water cavity; The coffee machine also includes an ice-making module, which is disposed in the refrigerator and located above the ice storage cavity. The ice-making module has an ice-making mode for making ice cubes and a cooling water mode for making cold water. The ice cubes made can fall into the ice storage cavity, and the cold water made can flow into the cold water cavity. The cold water cavity is connected to the coffee module and is used to provide cold water to the coffee module.

[0008] In some embodiments, the ice-making module includes: A spray element, located above the ice storage chamber, has multiple spray holes communicating with the cold water chamber; and An ice-making grid is disposed above the spray unit. The ice-making grid has multiple ice-making slots, the openings of which face the spray holes. The ice-making slots are used to exchange heat with water to make ice.

[0009] In some embodiments, a compressor and a condenser are also included, the compressor, the condenser and the ice tray being connected to form at least a portion of a refrigeration cycle; The refrigerator has a recessed lower rear side forming a clearance space, and the compressor and the condenser are disposed in the clearance space.

[0010] In some embodiments, the compressor and the condenser are arranged side by side in the clearance space along the left-right direction of the front panel, and the condenser is further away from the raw water tank than the compressor.

[0011] In some embodiments, the ice-making module further includes: A water receiving box is disposed between the ice-making grid and the ice storage cavity in a vertical direction, and together with the ice-making grid, they form a receiving cavity with an opening on one side. The spray element is supported on the bottom wall of the receiving cavity, and the opening communicates with the cold water cavity.

[0012] In some embodiments, the refrigerator includes: Box body; The inner liner structure, located within the box body, comprises a first chamber, a second chamber, and the cold water chamber, which are sequentially connected from top to bottom; and An ice storage shell is at least partially disposed in the second chamber and has the ice storage cavity, wherein the groove wall of the ice storage cavity has at least one water passage hole communicating with the cold water cavity; The water receiving box is located in the first chamber.

[0013] In some embodiments, the horizontal cross-sectional areas of the first chamber, the second chamber, and the cold water chamber decrease sequentially.

[0014] In some embodiments, the coffee module includes: The extraction pump has its inlet connected to the refrigerator. An extraction device is connected to the outlet of the extraction pump; The extraction pump and the extraction device are located on the front side of the front panel, with the extraction pump positioned above the extraction device.

[0015] In some embodiments, the coffee module further includes a flow meter, which is connected to and located upstream of the extraction pump, for detecting the inlet flow rate of the extraction pump.

[0016] In some embodiments, the coffee module further includes a noise reduction buffer connected to and located downstream of the extraction pump, for reducing water flow noise.

[0017] In some embodiments, the coffee module further includes a pressurized instant heating component, which is disposed between the front panel and the filter component along the front-rear direction of the front panel. The water inlet of the pressurized instant heating component is connected to the extraction pump, and the water outlet of the pressurized instant heating component is connected to the extraction device. The coffee machine has a hot brew mode and a cold brew mode. In the hot brew mode, the pressurized instant heating component is powered on to heat the flowing cold water; in the cold brew mode, the pressurized instant heating component is de-powered to allow cold water to pass through.

[0018] In some embodiments, the coffee module further includes a pure water tank, the pure water tank having a water inlet, a first water outlet and a second water outlet, the water inlet being connected to the water outlet of the filter assembly, the first water outlet being connected to the refrigerator, and the second water outlet being connected to the water inlet of the pressurized instant heating assembly. The pure water tank is located on the front side of the front panel and extends along the left-right direction of the front panel.

[0019] In some embodiments, the first water outlet and the second water outlet are arranged on the pure water tank in a left-right direction, wherein the first water outlet is closer to the refrigerator than the second water outlet, and the second water outlet is closer to the pressurized instant heating component than the first water outlet.

[0020] In some embodiments, the pure water tank is located above the extraction pump, and the lower surface of the pure water tank is recessed to form a clearance groove, with the extraction pump at least partially disposed within the clearance groove.

[0021] In the coffee machine provided in this embodiment, the refrigerator is located on one side along the left-right direction of the front panel, and the filter assembly and raw water tank are located on the other side. The raw water tank is positioned behind the filter assembly along the front-back direction, allowing the refrigerator, filter assembly, and raw water tank to be arranged adjacent to each other. This shortens the length of waterways such as the raw water delivery pipe between the raw water tank and the filter assembly, and the cold water return pipe between the raw water tank and the refrigerator, reducing the number of pipes and improving the compactness of the internal structure of the coffee machine. This balances the multi-functionality and miniaturization of the coffee machine. Furthermore, the orthographic projections of the refrigerator, filter assembly, and raw water tank in the direction perpendicular to the front panel all fall within the orthographic projection range of the front panel, preventing components from protruding outwards to the sides. This helps to reduce the width of the coffee machine's placement surface and improves space utilization. Attached Figure Description

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] This application provides a coffee machine that improves the structural compactness of the coffee machine and meets the requirements of miniaturized coffee machine design.

[0031] Specifically, please refer to Figures 1 to 3 The coffee machine in this embodiment includes a housing assembly 1, a front panel 11, a coffee module 3, a refrigerator 2, a filter assembly 4, and a raw water tank 5.

[0032] The outer casing assembly 1 includes a front panel 11, a base 12, a top plate 13, and a side plate 14. The front panel 11, base 12, top plate 13, and side plate 14 enclose each other to form an installation space. The refrigerator 2 and the filter assembly 4 are installed in the installation space. The outer casing assembly 1 can protect and prevent dust from the internal components, while also making the overall appearance of the machine neat.

[0033] In this embodiment, the coffee module 3 is at least partially disposed on the front side of the front panel 11 for extracting coffee concentrate. Part of the structure of the coffee module 3 is disposed on the front side of the coffee machine to facilitate the user's handling of coffee cups and operation.

[0034] The refrigerator 2 is located on the rear side of the front panel 11 and is connected to the coffee module 3. It is used to provide cold water for the cold brewing of the coffee module 3. An insulation layer can be installed on the outside of the refrigerator 2 to reduce the loss of cold water temperature inside the cabinet, improve the efficiency of cooling water and ensure the taste of cold brewed coffee.

[0035] The filter assembly 4 is located on the rear side of the front panel 11, arranged side-by-side with the refrigerator 2 along the left-right direction of the front panel 11. The water outlet of the filter assembly 4 is connected to the coffee module 3 and the refrigerator 2 respectively, and is used to filter the raw water to provide pure water for coffee extraction and the refrigerator 2. Exemplarily, the filter assembly 4 adopts a composite filter element structure. The filter assembly 4 includes a first filter element and a second filter element. The first filter element includes a pre-filter unit (such as a PP scale-inhibiting carbon rod) and a post-filter unit (such as a carbon rod). The water inlet of the pre-filter unit is connected to the raw water tank 5, and is used to intercept large particulate impurities, silt, etc. in the raw water, while also playing a scale-inhibiting role. The water outlet of the pre-filter unit is connected to the water inlet of the second filter element (such as an RO filter element). The RO filter element can further remove small impurities, heavy metal ions, etc. in the water, and improve the water purity. The water outlet of the second filter element is connected to the water inlet of the post-filter unit. The post-filter carbon rod is used to adsorb odors in the water and improve the taste of pure water. In this embodiment, the raw water in the raw water tank 5 flows sequentially through the pre-filter unit of the first filter element, the second filter element, and the post-filter unit. The filtered pure water can be delivered to the refrigerator 2 or the coffee module 3 to realize functions such as cold brewing, ice making, and direct drinking.

[0036] The raw water tank 5 is located behind the filter assembly 4 and is arranged side by side with the refrigerator 2 along the front panel 11. The raw water tank 5 is connected to the water inlet of the filter assembly 4 and is used to store raw water.

[0037] In this embodiment, along the left-right direction of the front panel 11, the refrigerator 2 is located on one side, and the filter assembly 4 and the raw water tank 5 are located on the other side. Furthermore, along the front-back direction, the raw water tank 5 is located behind the filter assembly 4, allowing the refrigerator 2, filter assembly 4, and raw water tank 5 to be arranged adjacent to each other in pairs. This shortens the length of waterways such as the raw water delivery pipe between the raw water tank 5 and the filter assembly 4, and the cold water return pipe between the raw water tank 5 and the refrigerator 2, reducing the number of pipes and improving the compactness of the coffee machine's internal structure, while also balancing the coffee machine's multi-functionality and miniaturization. Simultaneously, the orthographic projections of the refrigerator 2, filter assembly 4, and raw water tank 5 in the direction perpendicular to the front panel 11 all fall within the orthographic projection range of the front panel 11, preventing components from protruding outwards to the sides. This helps reduce the width of the coffee machine's placement surface and improves space utilization.

[0038] Please see Figure 4 In some embodiments, the dimension of the refrigerator 2 along the front-rear direction of the front panel 11 is defined as L, and the dimension along the left-right direction of the front panel 11 is defined as W, satisfying L > W. The above-mentioned dimensional settings make the refrigerator 2 have a long and narrow structure in the front-rear direction, which can adapt to the arrangement of the filter assembly 4 and the raw water tank 5 in the front-rear direction. It utilizes the space in the front-rear direction of the body, making the whole machine have a long and narrow layout, further reducing the width in the left-right direction, reducing the requirement for the width of the placement table, thereby improving the miniaturization level of the whole machine.

[0039] Please continue reading. Figure 5 and Figure 6 In some embodiments, the refrigerator 2 has an ice storage chamber 2A and a cold water chamber 2B that are connected to each other. The ice storage chamber 2A is located above the cold water chamber 2B, which allows for the separation of ice and cold water, facilitating ice storage and cold water supply. The coffee machine also includes an ice-making module 6, which is installed on the refrigerator 2 and located above the ice storage chamber 2A. The ice-making module 6 is used to supply ice to the ice storage chamber 2A and / or to supply cold water to the cold water chamber 2B. The ice-making module 6 has an ice-making mode and a cooling water mode. In the ice-making mode, the ice produced can fall into the ice storage chamber 2A for storage. In the cooling water mode, the low-temperature cold water produced can flow into the cold water chamber 2B. The cold water chamber 2B is connected to the coffee module 3 and is used to provide the cold water required for cold brewing, ensuring the taste of cold brew coffee.

[0040] Furthermore, in some embodiments, the ice-making module 6 includes a spray element 61 and an ice grid 62. The spray element 61 is located above the ice storage chamber 2A. Exemplarily, the spray element 61 has multiple spray holes facing the ice grid 62, and the spray holes are connected to the cold water chamber 2B for spraying cold water onto the ice grid 62 above. The ice grid 62 is disposed above the spray element 61, with its opening facing the spray holes. After water flows into the ice grid 62, it cools down and freezes through heat exchange, thus realizing the ice-making function. In this embodiment, the ice-making module 6 may include an evaporator, and the evaporator forms the ice grid 62, resulting in a more compact structure and higher heat exchange efficiency.

[0041] In some embodiments, such as Figure 3 As shown, the coffee machine also includes a compressor 63 and a condenser 64. The compressor 63, condenser 64, and ice tray 62 are connected by refrigerant pipes, forming at least part of the refrigeration cycle system to provide a cold source for ice making and chilled water. The lower surface of the ice tray 2 is recessed inward to form a clearance space 2C. The compressor 63 and condenser 64 are both located in the clearance space 2C. In this way, the compressor 63 and condenser 64 do not occupy additional effective space in the left-right and front-back directions inside the coffee machine, further improving the compactness of the overall structure. At the same time, the compressor 63 and condenser 64 are arranged close to the ice tray 2, shortening the refrigeration circuit connection pipes and improving the compactness of the structure.

[0042] In some embodiments, the compressor 63 and the condenser 64 are arranged side-by-side in the clearance space 2C along the left-right direction of the front panel 11, and the condenser 64 is further away from the original water tank 5 than the compressor 63. In this embodiment, the compressor 63 and the condenser 64 are arranged side-by-side, which can make full use of the width space at the bottom of the refrigerator 2, resulting in higher space utilization. At the same time, placing the condenser 64 in a relatively outer position is more conducive to heat exchange with the outside air, resulting in better heat dissipation, ensuring stable operation of the refrigeration system, and improving the rationality of the overall layout and operational reliability.

[0043] In this embodiment, the coffee machine is also equipped with an ice-making water circuit, which includes a circulation pipe and a circulation pump 66 mounted on the circulation pipe. One end of the circulation pipe is connected to the cold water chamber 2B, and the other end is connected to the ice-making module 6. In ice-making mode, the circulation pump 66 is activated to deliver cold water from the cold water chamber 2B to the ice tray 62 of the ice-making module 6 to make ice. In chilled water mode, the circulation pump 66 drives the water in the cold water chamber 2B to circulate between the circulation pipe and the cold water chamber 2B, continuously cooling it under the continuous cooling effect of the ice-making module 6 to produce chilled water.

[0044] In some embodiments, the ice-making module 6 further includes a water receiving box 65, which is disposed between the ice-making grid 62 and the ice storage cavity 2A in the vertical direction, and together with the ice-making grid 62 forms a receiving cavity with an opening on one side. The spraying component 61 is supported on the bottom wall of the receiving cavity, and the opening communicates with the cold water cavity 2B to provide a channel for water flow back.

[0045] In this embodiment, the spray element 61 has an overall inclined plate-like structure and is inclined downward toward the water receiving box 65. The spray element 61 can spray water upward toward the ice making tray 62, so that the water can exchange heat in the ice making tray 62 to form ice. The ice water and the cold water falling during the ice making process flow downward along the inclined spray element 61 toward the water receiving box 65. The bottom wall of the water receiving box 65 is inclined downward, so that the cold water can flow into the cold water chamber 2B through the opening along the inclined bottom wall.

[0046] In some embodiments, the refrigerator 2 includes a cabinet body 21, an inner liner structure 22, and an ice storage shell 23. The inner liner structure 22 is disposed inside the cabinet body 21 and has a first chamber 22A, a second chamber 22B, and a cold water chamber 2B connected sequentially from top to bottom, thus forming a layered structure. The ice storage shell 23 is at least partially disposed inside the second chamber 22B, and an ice storage chamber 2A is formed inside the ice storage shell 23. At least one water passage hole communicating with the cold water chamber 2B is provided on the groove wall of the ice storage chamber 2A. For example, the water passage hole is disposed on the bottom wall of the ice storage chamber 2A. A water receiving box 65 is disposed inside the first chamber 22A. The ice blocks produced can fall into the ice storage shell 23 along the spray member 61 and be conveyed to the ice outlet of the front panel 11 by the ice discharge auger, thereby completing the ice removal.

[0047] This embodiment fully utilizes the vertical space of the ice-making, ice-storing, and cold water-storing structures by stacking them vertically, thereby reducing the space occupied by the coffee machine in the width direction. This facilitates the narrow and elongated design of the coffee machine, reducing the width of the placement surface. At the same time, the cold water generated by the melting of ice in the ice storage cavity 2A can flow into the cold water cavity 2B through the water passage, which can both realize the recycling of water resources and maintain the low temperature of the cold water in the cold water cavity 2B, ensuring the supply of cold brew water.

[0048] In some embodiments, the first chamber 22A, the second chamber 22B, and the cold water chamber 2B are arranged sequentially from top to bottom, and their horizontal cross-sectional areas decrease sequentially. This embodiment, by gradually reducing the horizontal cross-sectional area, saves space in the lower part of the refrigerator 2 while ensuring the normal operation of ice making, ice storage, and cold water storage. This provides installation space for other functional components at the bottom of the coffee machine and also provides clearance for piping, further improving the overall compactness of the machine and facilitating miniaturized coffee machine design.

[0049] Please continue reading. Figures 7 to 9In some embodiments, the coffee module 3 includes an extraction pump 31 and an extraction device 32. The inlet of the extraction pump 31 is connected to the refrigerator 2 for supplying cold water from the refrigerator 2. The extraction device 32 is connected to the outlet of the extraction pump 31, and the extraction of coffee concentrate is achieved under the power provided by the extraction pump 31. Both the extraction pump 31 and the extraction device 32 are located on the front side of the front panel 11, with the extraction pump 31 positioned above the extraction device 32. This makes full use of the space on the front side of the front panel 11, saving more space for components such as the refrigerator 2, filter assembly 4, and raw water tank 5 on the rear side of the coffee machine. At the same time, the vertical arrangement saves space in the width direction of the coffee machine, further adapting to the narrow and compact design requirements of the entire machine. In addition, placing the extraction pump 31 above the extraction device 32 allows water to flow from top to bottom into the extraction device 32, which, combined with gravity flow, helps to improve water flow stability and extraction effect.

[0050] In some embodiments, the coffee module 3 further includes a flow meter 33, which is located upstream of the extraction pump 31 and disposed in the flow path between the refrigerator 2 and the extraction pump 31. The flow meter 33 is used to detect the water flow rate entering the extraction pump 31. In coffee extraction, the inlet water flow rate determines the extraction pressure and extraction effect. By detecting the flow rate parameter through the flow meter 33, the extraction pressure can be controlled, avoiding insufficient extraction due to flow fluctuations, thereby improving the quality and stability of coffee extraction.

[0051] In some embodiments, the coffee module 3 further includes a noise reduction buffer located downstream of the extraction pump 31 and disposed in the flow path between the extraction pump 31 and the extraction device 32. Since the extraction pump 31 outputs high water pressure during operation, it is prone to generating water flow noise. This embodiment uses the noise reduction buffer to stabilize the high-pressure water flow, reducing the noise caused by water flow impact, lowering the overall noise level of the coffee machine during operation, and improving the user experience.

[0052] In some embodiments, the coffee module 3 further includes a pressurized instant heating component 34. Along the front-rear direction of the front panel 11, the pressurized instant heating component 34 is disposed between the front panel 11 and the filter component 4. The front side of the pressurized instant heating component 34 is adjacent to the extraction pump 31. This arrangement shortens the connecting pipe between the extraction pump 31 and the pressurized instant heating component 34, making it easier to assemble and connect the pipe, while reducing water flow resistance. Along the left-right direction of the front panel 11, the pressurized instant heating component 34 is arranged side by side with the refrigerator 2, further shortening the connecting pipe between the pressurized instant heating component 34 and the refrigerator 2.

[0053] In this embodiment, the coffee machine has a hot brew mode and a cold brew mode. In the hot brew mode, the pressurized instant heating component 34 is powered on, and the heating element of the pressurized instant heating component 34 works to heat the flowing cold water instantly. The heated hot water is then delivered to the extraction device 32 to complete the hot brew. In the cold brew mode, the pressurized instant heating component 34 is de-powered, the heating element does not work, and the cold water flows directly through the inside of the pressurized instant heating component 34. In this way, there is no need to set up separate pipelines for cold brew or hot brew, saving the number of pipelines and further improving the compactness of the overall structure.

[0054] In some embodiments, such as Figure 8 As shown, the coffee module 3 also includes a pure water tank 35, which stores pure water filtered by the filter assembly 4 to provide pure water for the refrigerator 2 and the pressurized instant heating assembly 34. The pure water tank 35 is equipped with an inlet 351, a first outlet 352, and a second outlet 353. The inlet 351 is connected to the outlet of the filter assembly 4 to allow pure water to flow into the pure water tank 35; the first outlet 352 is connected to the refrigerator 2 to replenish it with pure water; and the second outlet 353 is connected to the inlet of the pressurized instant heating assembly 34 to provide pure water for cold brewing, hot brewing, and direct drinking water supply.

[0055] In this embodiment, the pure water tank 35 is located on the front side of the front panel 11, extending along the left and right direction of the front panel 11, and its orthographic projection in the direction perpendicular to the front panel 11 is within the orthographic projection range of the front panel 11, thereby avoiding the pure water tank 35 from protruding outwards to both sides and not increasing the width occupied by the entire machine's work surface; along the vertical direction, the pure water tank 35, the extraction pump 31, and the extraction device 32 are arranged sequentially. This vertical layered layout makes full use of the space in the height direction of the coffee machine, avoiding excessive width occupation in the horizontal direction, thus adapting to the narrow and long design of the entire machine. At the same time, the horizontally extended arrangement also makes full use of the width space on the front side of the front panel 11, improving the space utilization rate.

[0056] Furthermore, in some embodiments, the first water outlet 352 and the second water outlet 353 are spaced apart on the pure water tank 35 in a left-right direction, with the first water outlet 352 closer to the refrigerator 2 than the second water outlet 353, and the second water outlet 353 closer to the pressurized instant heating component 34 than the first water outlet 352. This arrangement results in shorter connecting pipes between the pure water tank 35 and the refrigerator 2 and pressurized instant heating component 34, reducing pipe length, simplifying pipe routing, avoiding pipe crossings, further improving the compactness of the internal structure of the coffee machine, and facilitating subsequent maintenance.

[0057] In some embodiments, the pure water tank 35 is located above the extraction pump 31, and the lower surface of the pure water tank 35 is recessed inward to form a relief groove 35A, in which the extraction pump 31 is at least partially disposed. This arrangement, combined with the aforementioned vertical layout, makes full use of the space in the height direction. By setting the relief groove 35A, it further saves the space occupied in the height direction of the entire machine, avoids the pure water tank 35 and the extraction pump 31 being arranged vertically, thus preventing the entire machine from being too tall. At the same time, it makes the layout of the pure water tank 35 and the extraction pump 31 more compact, further shortens the connecting pipeline between the two, and improves the overall structure.

[0058] In some embodiments, the dimension of the pure water tank 35 in the left-right direction is larger than its dimension in the front-back direction, thus making the pure water tank 35 an elongated shape extending in the left-right direction. This structural design can adapt to the width space on the front side of the front panel 11, making full use of the lateral space, and can also minimize the space occupied by the pure water tank 35 in the front-back direction, avoiding spatial interference with the filter assembly 4, raw water tank 5 and other components on the rear side, and further adapting to the compact layout of the whole machine in the front-back direction.

[0059] In some embodiments, the lowest water level of the pure water tank 35 is higher than the highest water level of the refrigerator 2, utilizing the level difference to achieve gravity water supply, eliminating the need for an additional water pump, simplifying the structure and reducing energy consumption. The pure water tank 35 is provided with an overflow channel 35B, which extends vertically. The inlet end is located inside the upper part of the pure water tank 35, and the outlet end extends from the bottom of the pure water tank 35 and connects to the refrigerator 2. The first outlet 352 is located at the outlet end of the overflow channel 35B. This arrangement saves on the use of valves, reduces the number of components, and further improves the structural compactness. In the left-right direction, the second outlet 353 is closer to the pressurized instant heating component 34 than the overflow channel 35B, and the overflow channel 35B is closer to the refrigerator 2 than the second outlet 353. This further shortens the connecting pipeline between the pure water tank 35 and the pressurized instant heating component 34 and the refrigerator 2, further optimizing the pipeline layout.

[0060] In some embodiments, the inlet 351 of the pure water tank 35 is located above the rear side of the pure water tank 35 and passes through the front panel 11 in the front-rear direction, communicating with the outlet of the filter assembly 4 located behind the front panel 11. In this way, excessive bends in the connecting pipe are avoided, the length of the connecting pipe between the inlet 351 and the filter assembly 4 is greatly shortened, the pipe layout is simplified, and the compactness and ease of assembly of the whole machine structure are further improved.

[0061] In some embodiments, such as Figure 9As shown, the coffee module 3 also includes a bracket 36, which is connected to the front panel 11. The connection method can be bolt fixing, snap-fit, or other methods. The pure water tank 35 is connected and installed on the bracket 36. Since the pure water tank 35 extends along the left and right direction of the front panel 11 and needs to store a certain volume of pure water, it has a certain weight. The bracket 36 provides a supporting carrier for the pure water tank 35, which can prevent the pure water tank 35 from becoming loose due to its own weight or water flow, thus improving the installation stability of the pure water tank 35.

[0062] To further improve structural compactness, in some embodiments, a cantilever 361 is provided on the bracket 36. The cantilever 361 can be integrally formed on the bracket 36 or connected to the bracket 36 via a detachable connection. The cantilever 361 can extend into the clearance groove 35A on the lower surface of the pure water tank 35, and the extraction pump 31 is connected to the cantilever 361. As described above, the clearance groove 35A on the lower surface of the pure water tank 35 is used to accommodate part of the extraction pump 31, and the cantilever 361 extends into the clearance groove 35A and supports the extraction pump 31, making the overall structure of the bracket 36, pure water tank 35 and extraction pump 31 more compact. This not only makes full use of the space of the clearance groove 35A and improves structural compactness, but also improves the overall integrity of the installation structure of the bracket 36, pure water tank 35 and extraction pump 31, reduces installation gaps, and further improves the overall operational stability of the machine.

[0063] In some embodiments, the cantilever 361 is provided with a groove 36A extending in the front-rear direction. Correspondingly, the extraction pump 31 is integrally formed or detachably connected with a slider 311 adapted to the groove 36A. The slider 311 can slide along the extension direction of the groove 36A. The extraction pump 31 is installed and disassembled through sliding engagement. During assembly, simply align the slider 311 of the extraction pump 31 with the groove 36A of the cantilever 361 and push it in in the front-rear direction to complete the installation. During disassembly, simply pull the extraction pump 31 out along the groove 36A in the opposite direction without disassembling the bracket 36 or other components. This greatly improves the ease of installation and disassembly of the extraction pump 31, facilitates subsequent maintenance, repair or replacement, and reduces maintenance costs.

[0064] In some embodiments, the refrigerator 2 is provided with a water inlet 221, which extends in the front-rear direction and passes through the front panel 11. One end of the water inlet 221 communicates with the interior of the refrigerator 2, and the other end is used to communicate with the outlet of the overflow channel 35B of the pure water tank 35, thereby enabling the pure water tank 35 to replenish water to the refrigerator 2. As mentioned above, the overflow channel 35B of the pure water tank 35 is used to discharge high-level pure water and replenish water to the refrigerator 2. In this embodiment, the water inlet 221 passes through the front panel 11 and communicates with the overflow channel 35B, reducing the number of bends in the connecting pipes, further shortening the length of the water replenishment pipe between the pure water tank 35 and the refrigerator 2, simplifying the pipe layout, and further improving the compactness of the overall structure.

[0065] In some embodiments, the coffee machine, in addition to the original cold brew and hot brew modes, also has a room temperature water supply mode and a hot water supply mode to meet the user's direct drinking needs. In the hot water supply mode, the pressurized instant heating component 34 is powered on, and the heating element inside the pressurized instant heating component 34 works to instantly heat the room temperature water flowing out of the pure water tank 35. After heating to the preset temperature, it is output to meet the user's need for hot water. In the room temperature water supply mode, the pressurized instant heating component 34 is de-powered, the heating element does not work, and the room temperature water in the pure water tank 35 flows directly through the pressurized instant heating component 34 before being output.

[0066] In this embodiment, room temperature water and hot water supply share a single pressurized instant heating component 34 and a water circuit, eliminating the need for separate heating components and pipelines for room temperature water and hot water. This saves on the number of pipelines and components, further simplifies the internal layout of the coffee machine, and improves the overall structural compactness.
