Description

Technical Field

[0001] This invention relates to the water system of steam dehydrators and coffee machines. Background Technology

[0002] Current coffee machines typically need to provide both steam and hot water functions. Steam is generally produced by heating water with a heating element, but the steam often contains a certain amount of liquid water during output, resulting in lower steam dryness and affecting its effectiveness. This is especially problematic in applications like milk frothing, where high water content can lead to unstable steam output and reduced milk froth quality.

[0003] On the other hand, existing coffee machines typically require a separate hot water heating element or independent hot water flow path to reheat the water entering the brewing head in order to provide hot water. This structure not only makes the overall water circuit structure of the machine more complex, but also increases the number of parts, assembly difficulty, and manufacturing costs. It is also not conducive to the miniaturization and integrated design of the entire machine.

[0004] Therefore, the existing technology has at least the following technical problems: (1) The existing steam output structure has limited dehydration effect, and liquid water is easily carried in the output steam, resulting in low steam dryness; (2) The existing steam flow path and hot water flow path are usually independent of each other, requiring additional hot water heating components, which leads to complex structure; (3) The existing scheme has low integration of functions such as steam dehydration, hot water preparation and condensate discharge, which is not conducive to reducing costs and reducing equipment volume. Summary of the Invention

[0005] To at least solve one of the above-mentioned technical problems in the prior art, the present invention aims to provide a steam dehydrator for improving steam dryness.

[0006] To at least solve one of the above-mentioned technical problems in the prior art, the present invention aims to provide a steam dehydrator that improves steam dryness while having a water heating function.

[0007] To at least solve one of the above-mentioned technical problems in the prior art, the present invention aims to provide a water system for a coffee machine.

[0008] The first objective of this invention is achieved through the following technical solution:

[0009] A steam dehydrator includes a housing with a steam-liquid communication port at the bottom and a steam outlet at the top. A flow guide channel is provided inside the housing, and a steam dehydration component for reducing the steam moisture content is built into the flow guide channel. The steam-liquid communication port is connected to the inlet of the flow guide channel, and the steam outlet is connected to the outlet of the flow guide channel, so that steam entering the housing through the steam-liquid communication port flows along the flow guide channel and contacts the steam dehydration component.

[0010] By setting a flow guide channel and a steam dehydration component inside the shell, the steam enters from the bottom vapor-liquid connection port and flows along the flow guide channel. During the flow, the steam comes into contact with the steam dehydration component and is then discharged from the top steam outlet. This helps to extend the flow path of the steam inside the shell and improve the gas-liquid separation effect of the steam during the flow process, thereby reducing the content of entrained liquid components in the steam, increasing the dryness of the output steam, and thus improving the steam utilization effect.

[0011] Furthermore, it also includes a spiral rod, which includes a rod body and a spiral steam dehydration component. The spiral steam dehydration component is wound along the length of the rod body. The spiral rod is disposed inside the housing, and the spiral steam dehydration component, the inner wall of the housing, and the rod body form a spiral flow channel.

[0012] By setting a spiral rod and using the spiral steam dehydration components, the inner wall of the shell, and the rod to form a spiral flow channel, the internal flow structure of the steam dehydrator can be made more concentrated and compact, forming a longer steam flow path in a smaller structural space. This is beneficial to further improve the steam dehydration effect while taking into account the compactness of the structural layout.

[0013] Furthermore, the housing includes an upper housing and a bottom cover, the upper housing and the bottom cover are threadedly connected, the vapor-liquid communication port is located at the bottom of the bottom cover, and the steam outlet is located at the top of the upper housing.

[0014] By using a threaded connection between the upper shell and the bottom cover, and placing the vapor-liquid connection port and the steam outlet at the upper and lower ends of the shell respectively, it is beneficial to form a clearer steam flow path, while also facilitating assembly, disassembly and maintenance.

[0015] Furthermore, the bottom of the housing is provided with a water inlet and a condensate outlet, the top of the housing is provided with a hot water outlet, and the housing is provided with a water heating channel; the water inlet is connected to the inlet of the water heating channel, the outlet of the water heating channel is connected to the hot water outlet, and the condensate outlet is connected to the inner cavity of the housing.

[0016] By further adding an inlet, a hot water outlet, a condensate outlet, and a water heating channel to the steam dehydrator, the same device can not only dehydrate steam, but also heat water and output hot water, and discharge the separated condensate. This facilitates the integration of steam dehydration, hot water preparation, and condensate discharge functions into the same structure, thereby improving the problems of existing steam flow paths and hot water flow paths being usually independent, requiring additional hot water heating components, and having low system integration.

[0017] Furthermore, a balance valve is provided on the top of the housing.

[0018] By installing a balancing valve at the top of the shell, it is beneficial to balance and regulate the internal pressure of the shell, thereby making the internal pressure state of the steam dehydrator more stable during operation, which in turn helps to improve the stability of the steam output and hot water output process.

[0019] Furthermore, a one-way valve is provided at the condensate outlet.

[0020] By installing a check valve at the condensate outlet, the possibility of external liquids or gases flowing back into the housing cavity through the condensate outlet can be reduced, which helps to maintain the stability of the fluid flow direction inside the housing and improves the reliability of the condensate discharge process.

[0021] Furthermore, it also includes a spiral rod and a third heating assembly. The spiral rod includes a rod body extending vertically and a spiral steam dehydration component. The spiral steam dehydration component is wound along the length of the rod body. The spiral rod is disposed within a housing. The spiral steam dehydration component, the inner wall of the housing, and the rod body form a spiral flow channel. The inner cavity of the rod body forms the water heating channel. The third heating assembly is disposed within the housing and is used to heat the water in the water heating channel. The water inlet is connected to the inlet of the rod body, and the outlet of the rod body is connected to the hot water outlet.

[0022] By setting up a rod that runs through the vertical direction and forming a water heating channel in the inner cavity of the rod, and using a third heating component to heat the water in the water heating channel, the steam dehydration structure and the hot water heating structure are further integrated into one unit. This helps to reduce the setting of independent hot water heating components, simplify the overall structure, and improve the integration of hot water and steam functions.

[0023] Furthermore, the housing includes a top cover, an upper housing, and a bottom cover. The steam outlet and the hot water outlet are located on the top cover, the vapor-liquid communication port, the water inlet, and the condensate outlet are located on the bottom cover, and the third heating component is located on the bottom cover and at the corresponding position of the rod.

[0024] By further defining the specific structures of the top cover, upper shell, and bottom cover, as well as the positional relationships of the steam outlet, hot water outlet, steam-liquid connection port, water inlet, condensate outlet, and third heating component, the arrangement of the steam flow path, hot water flow path, and condensate discharge path becomes clearer and more compact. This helps to reduce the size of the device and improve the rationality of the structural layout, thereby further enhancing the integration level of the device.

[0025] The second objective of this invention is achieved through the following technical solution:

[0026] A water system for a coffee machine includes a water tank, a water pump, a one-way valve, a solenoid valve, a first heating element, a steam dehydrator, a steam valve, a steam nozzle, a flow meter, a second heating element, a balancing valve, and a brewing head. The inlet of the water pump is connected to the outlet of the water tank, the outlet of the water pump is connected to the inlet of the one-way valve, and the outlet of the one-way valve is connected to the inlet of the solenoid valve. The first outlet of the solenoid valve is connected to the inlet of the first heating element. The steam output end of the first heating element is connected to the vapor-liquid connection port of the steam dehydrator. The steam outlet of the steam dehydrator is connected to the inlet of the steam valve, and the outlet of the steam valve is connected to the steam nozzle. The second outlet of the solenoid valve is connected to the inlet of the flow meter, the outlet of the flow meter is connected to the inlet of the second heating element, the outlet of the second heating element is connected to the brewing head, and the balancing valve is disposed on the second heating element.

[0027] By placing the steam dehydrator in the steam branch, the steam generated by the first heating element is processed by the steam dehydrator before entering the steam valve and steam nozzle, while the brewing branch supplies water to the brewing head through the flow meter and the second heating element. This allows both steam and brewing functions to be taken into account in the same coffee machine water system, and helps to improve the quality of steam output.

[0028] The third objective of this invention is achieved through the following technical solution:

[0029] A water system for a coffee machine includes a water tank, a water pump, a one-way valve, a solenoid valve, a first heating element, a steam dehydrator, a steam valve, a steam nozzle, a flow meter, a drain valve, a brewing head, and a water collection box. The inlet of the water pump is connected to the outlet of the water tank, the outlet of the water pump is connected to the inlet of the one-way valve, and the outlet of the one-way valve is connected to the inlet of the solenoid valve. The first outlet of the solenoid valve is connected to the inlet of the first heating element, the steam output end of the first heating element is connected to the vapor-liquid connection port of the steam dehydrator, the steam outlet of the steam dehydrator is connected to the inlet of the steam valve, and the outlet of the steam valve is connected to the steam nozzle. The second outlet of the solenoid valve is connected to the inlet of the flow meter, the outlet of the flow meter is connected to the inlet of the steam dehydrator, the hot water outlet of the steam dehydrator is connected to the brewing head, the condensate outlet of the steam dehydrator is connected to the inlet of the drain valve, and the outlet of the drain valve is connected to the water collection box.

[0030] By using a steam dehydrator with a water inlet, hot water outlet, and condensate outlet, the steam branch, hot water output branch, and condensate discharge branch can be integrated around the same steam dehydrator. This not only facilitates the coordinated operation of steam dehydration, hot water output, and condensate discharge, but also reduces the need for additional hot water heating components and independent hot water flow paths, thereby improving the integration of the coffee machine's water system.

[0031] Beneficial effects of the present invention

[0032] This invention improves the gas-liquid separation effect in the steam by setting a flow guide channel inside the steam dehydrator and setting a steam dehydration component inside the flow guide channel, so that the steam comes into contact with the steam dehydration component during the flow of the steam in the shell, thereby reducing the content of entrained liquid components in the steam and increasing the dryness of the output steam, thus improving the steam utilization effect.

[0033] By adopting a structure of screw rod and spiral steam dehydration component, this invention can form a longer steam flow path in a smaller structural space, making the steam dehydration structure more compact and further improving the steam dehydration effect, while also taking into account the convenience of assembly and maintenance.

[0034] The steam dehydrator of this invention can not only be used for steam dehydration, but also realize hot water heating, hot water output and condensate discharge functions by setting up a water inlet, a water heating channel, a hot water outlet, a condensate outlet and a third heating component. This is conducive to integrating steam dehydration, hot water preparation and liquid discharge functions into the same device, reducing the setting of independent hot water heating components and independent hot water flow paths, and thus simplifying the overall structure of the machine.

[0035] This invention applies the steam dehydrator to the water circuit system of a coffee machine, enabling a more reasonable integrated arrangement of the steam branch, brewing branch, hot water output branch, and condensate discharge branch. This helps to reduce system complexity, improve overall machine integration, and facilitate the miniaturization of the entire machine while achieving steam, hot water, and brewing functions.

[0047] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0048] Example 1, see Figures 1 to 3 As shown, this embodiment 1 provides a steam dehydrator 10, including a housing 1. The bottom of the housing 1 is provided with a steam-liquid communication port 11, and the top is provided with a steam outlet 12. A flow guiding channel 130 is provided inside the housing 1. The flow guiding channel 130 is equipped with a steam dehydration component 13 for reducing the moisture content of the steam. The steam-liquid communication port 11 is connected to the inlet of the flow guiding channel 130, and the steam outlet 12 is connected to the outlet of the flow guiding channel 130, so that the steam entering the housing 1 through the steam-liquid communication port 11 flows along the flow guiding channel 130 and contacts the steam dehydration component 13.

[0049] Furthermore, the steam dehydrator 10 in this embodiment 1 also includes a spiral rod 2, which includes a rod body 21 and a spiral steam dehydration component 13. The spiral steam dehydration component 13 is wound along the length direction of the rod body 21. The spiral rod 2 is disposed inside the housing 1. The spiral steam dehydration component 13, the inner wall of the housing 1, and the rod body 21 form a spiral guide channel 130.

[0050] Furthermore, the housing 1 includes an upper housing 100 and a bottom cover 200, the upper housing 100 and the bottom cover 200 are threadedly connected, the vapor-liquid communication port 11 is located at the bottom of the bottom cover 200, and the steam outlet 12 is located at the top of the upper housing 100.

[0051] In this embodiment 1, steam enters the interior of the housing 1 through the vapor-liquid connection port 11 and flows upward along the guide channel 130. During the flow, the steam comes into contact with the steam dehydration component 13, and the liquid components entrained in the steam are facilitated to separate from the main steam component, thereby improving the steam output quality. The steam after dehydration is discharged from the top steam outlet 12 for use by subsequent steam-using components.

[0052] In this embodiment 1, by setting the spiral rod 2 and the spiral steam dehydration component 13, a longer steam flow path can be formed in a small installation space, which is beneficial to improving the steam dehydration effect. At the same time, the upper shell 100 and the bottom cover 200 are connected by threads, which makes the structure relatively simple and easy to assemble, disassemble and maintain.

[0053] It should be understood that in this embodiment 1, the steam dehydration component 13 is preferably a spiral structure, but it is not limited to this. As long as it can be set in the flow channel 130 and play a dehydration role in the steam flow process, it can be used.

[0054] Example 2, see Figure 4 As shown, this embodiment 2 provides a water system for a coffee machine, including a water tank 6, a water pump 7, a one-way valve 4, a solenoid valve 8, a first heating component 9, a steam dehydrator 10, a steam valve 20, a steam nozzle 30, a flow meter 40, a second heating component 50, a balance valve 3, and a brewing head 60.

[0055] The inlet of the water pump 7 is connected to the outlet of the water tank 6, the outlet of the water pump 7 is connected to the inlet of the one-way valve 4, and the outlet of the one-way valve 4 is connected to the inlet of the solenoid valve 8. The first outlet of the solenoid valve 8 is connected to the inlet of the first heating component 9, the steam output end of the first heating component 9 is connected to the steam-liquid connection port 11 of the steam dehydrator 10, the steam outlet 12 of the steam dehydrator 10 is connected to the inlet of the steam valve 20, and the outlet of the steam valve 20 is connected to the steam nozzle 30. The second outlet of the solenoid valve 8 is connected to the inlet of the flow meter 40, the outlet of the flow meter 40 is connected to the inlet of the second heating component 50, the outlet of the second heating component 50 is connected to the brewing head 60, and the balancing valve 3 is disposed on the second heating component 50.

[0056] The steam dehydrator 10 in this embodiment 2 can adopt the structure of embodiment 1. During operation, water in the water tank 6 is transported to the solenoid valve 8 through the check valve 4 by the water pump 7. The solenoid valve 8 is used to control the water flow and select different flow branches.

[0057] When the coffee machine needs to output steam, the solenoid valve 8 opens the first outlet, allowing water to flow into the first heating element 9. The steam generated after being heated by the first heating element 9 enters the steam dehydrator 10. Within the steam dehydrator 10, it flows along the guide channel 130 and contacts the steam dehydration component 13 before being discharged from the steam outlet 12 and output through the steam valve 20 and steam nozzle 30. Because the steam is processed by the steam dehydrator 10 before entering the steam nozzle 30, it helps improve steam quality.

[0058] Furthermore, in this embodiment 2, the condensate separated during the steam flow within the steam dehydrator 10 can be returned to the first heating component 9 via the steam-liquid connection 11, and reheated within the first heating component 9 to form steam again. This allows some of the condensate generated during the steam dehydration process to be reused, improving water utilization and reducing emissions.

[0059] When the coffee machine needs to brew, the solenoid valve 8 opens the second outlet, and the water flows through the flow meter 40 and the second heating element 50 before being delivered to the brewing head 60 to achieve the brewing function. The flow meter 40 is used to detect the amount of water flowing through this branch, and the balancing valve 3 is used to regulate the fluid pressure at the second heating element 50.

[0060] In this embodiment 2, by setting a steam dehydrator 10 in the steam branch, the steam output path and the boiling water supply path are set separately, which can realize both steam function and boiling function, and the structure is relatively clear. At the same time, the condensate separated in the steam dehydrator 10 can flow back to the first heating component 9 to participate in the steam generation process again, thus helping to improve the overall water utilization efficiency of the system.

[0061] Example 3, see Figures 5 to 10 As shown, this embodiment 3 provides a steam dehydrator 10, including a housing 1. The bottom of the housing 1 is provided with a steam-liquid communication port 11, and the top is provided with a steam outlet 12. A flow guiding channel 130 is provided inside the housing 1. The flow guiding channel 130 is equipped with a steam dehydration component 13 for reducing the moisture content of steam. The steam-liquid communication port 11 is connected to the inlet of the flow guiding channel 130, and the steam outlet 12 is connected to the outlet of the flow guiding channel 130, so that the steam entering the housing 1 through the steam-liquid communication port 11 flows along the flow guiding channel 130 and contacts the steam dehydration component 13.

[0062] In this embodiment 3, the bottom of the housing 1 is also provided with a water inlet 14 and a condensate outlet 15, the top of the housing 1 is also provided with a hot water outlet 16, and the housing 1 is also provided with a water heating channel 17. The water inlet 14 is connected to the inlet of the water heating channel 17, the outlet of the water heating channel 17 is connected to the hot water outlet 16, and the condensate outlet 15 is connected to the inner cavity of the housing 1.

[0063] Furthermore, a balancing valve 3 is provided at the top of the housing 1. The balancing valve 3 helps to balance the pressure inside the housing 1. A one-way valve 4 is provided at the condensate outlet 15 to reduce the possibility of external liquids or gases flowing back into the inner cavity of the housing 1 through the condensate outlet 15.

[0064] Furthermore, the steam dehydrator 10 in this embodiment also includes a spiral rod 2 and a third heating component 5. The spiral rod 2 includes a rod body 21 that runs through the vertical direction and a spiral steam dehydration component 13. The spiral steam dehydration component 13 is wound along the length direction of the rod body 21. The spiral rod 2 is disposed inside the housing 1. The spiral steam dehydration component 13, the inner wall of the housing 1, and the rod body 21 form a spiral guide channel 130.

[0065] The inner cavity of the rod 21 forms the water heating channel 17. The third heating component 5 is disposed inside the housing 1 and is used to heat the water in the water heating channel 17. The water inlet 14 is connected to the inlet of the rod 21, and the outlet of the rod 21 is connected to the hot water outlet 16.

[0066] Furthermore, the housing 1 includes a top cover 300, an upper housing 100, and a bottom cover 200. The steam outlet 12 and the hot water outlet 16 are disposed on the top cover 300. The vapor-liquid communication port 11, the water inlet 14, and the condensate outlet 15 are disposed on the bottom cover 200. The third heating component 5 is disposed on the bottom cover 200 and located at the corresponding position of the rod 21.

[0067] In this embodiment 3, steam enters the housing 1 through the vapor-liquid connection port 11 and flows along the guide channel 130, contacting the steam dehydration component 13 during its flow, and finally exiting through the steam outlet 12. During this process, the liquid components entrained in the steam can be separated within the housing 1 and discharged through the condensate outlet 15, which communicates with the inner cavity of the housing 1. Simultaneously, external water can enter the water heating channel 17 through the water inlet 14, be heated by the third heating component 5, and output through the hot water outlet 16.

[0068] Furthermore, during the heating of the water heating channel 17 within the rod body 21 by the third heating component 5, heat can also be transferred via the rod body 21 to the adjacent steam dehydration component 13 and the guide channel 130, thereby providing auxiliary heating for the steam flowing along the guide channel 130. This reduces heat loss during steam flow, lowers the likelihood of recondensation of liquid components in the steam, and consequently improves the steam dehydration effect and the dryness of the output steam.

[0069] Therefore, the steam dehydrator 10 in this embodiment can not only perform steam dehydration but also hot water heating and output functions, which helps to improve the structural integration and reduce the need for independent hot water heating components.

[0070] It should be understood that in this embodiment 3, the steam dehydration component 13 is preferably a spiral structure, but it is not limited to this. Any component that can be installed within the flow channel 130 and play a dehydration role during steam flow can be used. The third heating component 5 can adopt a structure suitable for heating the water in the water heating channel 17. Any component that can achieve the steam dehydration and hot water output functions of this application can be used. See Embodiment 4. Figure 11 As shown, this embodiment 4 provides a water system for a coffee machine, including a water tank 6, a water pump 7, a one-way valve 4, a solenoid valve 8, a first heating component 9, a steam dehydrator 10, a steam valve 20, a steam nozzle 30, a flow meter 40, a drain valve 70, a brewing head 60, and a water collection box 80.

[0071] The inlet of the water pump 7 is connected to the outlet of the water tank 6, the outlet of the water pump 7 is connected to the inlet of the one-way valve 4, and the outlet of the one-way valve 4 is connected to the inlet of the solenoid valve 8. The first outlet of the solenoid valve 8 is connected to the inlet of the first heating component 9, the steam output end of the first heating component 9 is connected to the vapor-liquid connection port 11 of the steam dehydrator 10, the steam outlet 12 of the steam dehydrator 10 is connected to the inlet of the steam valve 20, and the outlet of the steam valve 20 is connected to the steam nozzle 30. The second outlet of the solenoid valve 8 is connected to the inlet of the flow meter 40, the outlet of the flow meter 40 is connected to the water inlet 14 of the steam dehydrator 10, the hot water outlet 16 of the steam dehydrator 10 is connected to the brewing head 60, the condensate outlet 15 of the steam dehydrator 10 is connected to the inlet of the drain valve 70, and the outlet of the drain valve 70 is connected to the water receiving box 80.

[0072] The steam dehydrator 10 in this embodiment 4 can adopt the structure of embodiment 3. During operation, water from the water tank 6 enters the one-way valve 4 under the action of the water pump 7 and is then delivered to the solenoid valve 8. The solenoid valve 8 is used to switch the water flow between different functional branches.

[0073] When the coffee machine needs to output steam, the solenoid valve 8 opens the first outlet, and water enters the first heating element 9. After being heated by the first heating element 9 to form steam, the steam enters the steam dehydrator 10. The steam flows along the guide channel 130 in the steam dehydrator 10 and comes into contact with the steam dehydration component 13. It is then output from the steam outlet 12 and discharged through the steam valve 20 and the steam nozzle 30 to achieve the steam function.

[0074] When the coffee machine needs to output hot water or brew, the solenoid valve 8 opens the second outlet, and the water passes through the flow meter 40 and then enters the internal water heating channel 17 of the steam dehydrator 10 through the inlet 14. After being heated by the third heating component 5, the water is output from the hot water outlet 16 of the steam dehydrator 10 to the brewing head 60, thereby realizing the output of hot water or the supply of water for brewing.

[0075] The condensate generated during the steam dehydration process can be discharged from the condensate outlet 15 of the steam dehydrator 10 and collected in the water collection box 80 via the drain valve 70. Thus, the coffee machine water circuit system in this embodiment 4 can integrate functions such as steam dehydration, hot water heating, and condensate discharge into the same steam dehydrator 10, thereby simplifying the overall water circuit structure, reducing the number of independent heating components required for the hot water function, and improving the overall integration of the machine.

[0076] In the above embodiments, both the first heating component 9 and the second heating component 50 can be boilers, and the third heating component 5 can be a heating rod. Specifically, the first heating component 9 heats the water in the steam branch to generate steam, the second heating component 50 heats the water in the boiling branch, and the third heating component 5 heats the water in the water heating channel 17.

[0077] In the above embodiments, the steam dehydration component 13 is preferably a metal steam dehydration component 13. After entering the shell through the steam-liquid connection port, the steam flows along the guide channel and comes into contact with the metal steam dehydration component 13 during the flow. As the steam flow path is extended and the flow direction changes continuously, the liquid droplets entrained in the steam are easily attached to the surface of the metal steam dehydration component 13 and gradually converge to form larger droplets under the action of inertial collision, centrifugal separation, surface adhesion and coagulation. The formed droplets fall back or are discharged under the action of gravity, thereby reducing the liquid components entrained in the steam that continues to flow forward, and thus reducing the water content of the steam.

[0078] Furthermore, the metal steam dehydration component 13 has good structural strength and thermal conductivity. In the structure described in Example 3, it can also be used in conjunction with a third heating component to transfer heat, thereby reducing heat loss of steam during the flow process and reducing the possibility of recondensation of liquid components, which is conducive to further improving the steam dehydration effect and the dryness of the output steam.
