Description

Technical Field

[0001] This invention belongs to the field of coffee machine technology, and specifically relates to an iced coffee machine. Background Technology

[0002] With the improvement of living standards and the diversification of consumption habits, people's requirements for beverages are no longer limited to traditional hot drinks. Iced coffee, iced milk tea, chilled juice and other iced drinks are becoming increasingly popular among consumers due to their unique taste and cooling effect, especially among young people and in office settings, where the demand for iced drinks is rising year by year.

[0003] Currently, there are many types of coffee machines on the market, mainly including drip, capsule, and espresso machines. Most existing coffee machines only have heating functions and lack cooling or ice-making capabilities. When a user wants to make an iced coffee, the traditional method is to first prepare hot coffee using the coffee machine, and then rely on external sources (such as a home refrigerator or a separate ice maker) to provide ice for physical cooling. This process is noticeably delayed and dependent. If ice is not prepared in advance at home or in the office, the user cannot immediately enjoy an iced drink, resulting in a poor user experience.

[0004] To meet the demand for iced drinks, current technology forces users to adopt a combination of a coffee machine and an ice maker. This approach has the following drawbacks: 1. Low space utilization: Whether it's a home kitchen countertop or an office break room, space is usually quite limited. Placing two or more independent devices at the same time will take up a lot of workspace and affect the aesthetics and tidiness of the environment.

[0005] 2. High purchase cost: Buying a standalone ice maker means additional hardware expenditure, increasing the economic burden on consumers.

[0006] 3. Maintenance is cumbersome. Two or more devices need to be cleaned, descaled, and refilled with water separately, which increases the user's maintenance costs and time.

[0007] Therefore, there is an urgent need to design a coffee machine that can extract coffee and provide ice in home use scenarios to improve the taste of specialty coffees. Summary of the Invention

[0008] The purpose of this invention is to disclose an iced coffee machine that at least solves the problems mentioned in the background art, such as the limited functions of traditional coffee machines, the need to purchase multiple machines, and the cumbersome operation of multiple machines.

The second heating assembly is connected to the first heating assembly, and the first heating assembly supplies hot water to the second heating assembly. The second heating assembly further heats the hot water supplied by the first heating assembly to obtain steam, which is then output through the steam nozzle. The first heating assembly can simultaneously supply hot water to both the extraction assembly and the second heating assembly. A fifth pipe is connected to the outlet of the first heating component, and the fifth pipe is connected to the second heating component. A fifth control valve is installed on the fifth pipe.

[0014] As an optional implementation, the iced coffee machine also includes a water dispensing component, wherein the first heating component supplies heated water to the water dispensing component, and the water dispensing component includes a first water outlet and a second water outlet; A sixth pipe is also connected to the outlet of the first heating component, and the sixth pipe is connected to the first water outlet of the drinking water component.

[0015] As an optional implementation, a seventh pipeline is connected to the second water outlet of the drinking water assembly. The seventh pipeline is connected to the water source assembly. A second pump body is installed on the seventh pipeline, and a seventh control valve is also installed on the seventh pipeline. The outlet of the seventh control valve is connected to the inlet of the second pump body.

[0016] As an alternative implementation, the iced coffee machine further includes a cold water assembly, which includes a cold water tank configured to store low-temperature cold water; the cold water tank is configured to supply low-temperature cold water to the drinking assembly and the extraction assembly. The cold water tank is connected to an eighth pipeline, which is connected to the inlet of the second pump body, and an eighth control valve is installed on the eighth pipeline. The cold water tank is connected to a ninth pipeline, and a two-inlet-one-outlet control valve is connected to the ninth pipeline. One inlet of the two-inlet-one-outlet control valve is connected to the ninth pipeline, the other inlet of the two-inlet-one-outlet control valve is connected to the water tank, and the outlet of the two-inlet-one-outlet control valve is connected to the inlet of the first pump body.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: The iced coffee machine of this invention, with the addition of an ice-making component, enables the preparation of ice cubes, directly endowing the coffee machine with the ability to make cold drinks, thus expanding its functionality beyond a single extraction function. Through the built-in ice-making mechanism, storage box, and ice outlet, the device can independently and instantly produce and supply ice cubes, thereby meeting users' needs for making iced coffee, iced milk tea, and other chilled beverages.

[0036] The technical solution of the present invention will be further described below with reference to the embodiments and accompanying drawings.

[0037] Please see Figure 1 As shown in the figure, this application provides an iced coffee machine.

[0038] In one embodiment, the iced coffee machine includes an extraction component 1, a first heating component 3, and a water source component 22.

[0039] The extraction assembly is used to output extraction water. The first heating assembly is connected to the extraction assembly and supplies heated extraction water to the extraction assembly. The water source assembly supplies water to the first heating assembly and / or the extraction assembly.

[0040] In this embodiment, by setting a first heating component and supplying hot water to the extraction component, this iced coffee machine has the function of preparing hot extraction.

[0041] Hot extraction of coffee efficiently extracts flavor compounds from coffee grounds in a very short time (usually 20-30 seconds), resulting in a coffee with a rich, full-bodied flavor profile. As the mainstream method of coffee making, hot extraction is suitable for most coffee bean varieties and roast levels. Whether it's a dark roast espresso or a light roast pour-over, hot extraction can achieve stable and predictable results by adjusting the water temperature. This characteristic makes coffee machines dominant in both commercial and home use. Therefore, in this embodiment, the most important function of the coffee machine is to provide hot water to the extraction unit through a first heating element.

[0042] In this embodiment, the water source component supplies water to the first heating component and the extraction component. The water source supplies water to the extraction component, achieving room temperature extraction, increasing the extraction modes of the coffee machine, and improving the taste of the brewed coffee.

[0043] The water source component supplies water to the first heating component, which in turn supplies hot water for coffee extraction to the extraction component, thus enabling the coffee machine to perform hot extraction.

[0044] In this embodiment, an ice-making component 40 is added. The ice-making component 40 includes an ice-making mechanism, an ice storage box, an automatic ice dispensing component, and an ice outlet 43. The automatic ice dispensing component automatically transports ice cubes from the ice storage box to the ice outlet 43 and outputs the ice cubes from the outlet 43. By adding this component, the coffee machine gains the function of making ice cubes. In this embodiment, the ice-making function is integrated into the coffee machine, eliminating the need for users to purchase two separate appliances. This not only saves valuable counter space in the kitchen or office area but also reduces overall equipment procurement and maintenance costs, achieving a "one machine, multiple uses" design.

[0045] In this embodiment, the addition of an ice-making component directly endows the coffee machine with the ability to prepare cold drinks, freeing it from being limited to a single hot extraction or extraction function. Through the built-in ice-making mechanism, storage box, and ice outlet 43, it can independently and instantly produce and supply ice, thereby meeting the user's needs for making iced coffee, iced milk tea, and other chilled beverages.

[0046] In this embodiment, the ice-making component is combined with room temperature extraction to achieve the function of preparing iced coffee, and the prepared iced coffee has a better taste and is more in line with the preparation process of iced coffee.

[0047] In this embodiment, the hot extraction function of the coffee machine is combined with the ice-making function to obtain iced coffee, and a balance can be achieved between "hot extracted coffee with a rich aroma" and "iced coffee with a refreshing taste".

[0048] In one embodiment, the iced coffee machine also includes an automatic cup delivery component 70. The automatic cup delivery component 70 is located at least below the ice outlet 43 and the extraction component, and is configured to deliver the cup below the ice outlet 43 to the area below the extraction component, and / or deliver the cup below the extraction component to the area below the ice outlet 43.

[0049] When preparing iced coffee, the user simply places the cup under the ice outlet 43. The automatic ice dispensing component delivers ice from the ice storage box to the ice outlet 43, from which it falls onto the cup on the automatic cup delivery component 70 below the ice outlet 43. The automatic cup delivery component 70 then delivers the cup containing ice to the extraction component to receive the extracted coffee extract. Alternatively, when preparing coffee, the user first places the cup under the extraction component and onto the automatic cup delivery component 70. After all the extract has flowed into the cup, the automatic cup delivery component 70 automatically delivers the cup containing the extract to the ice outlet 43. The automatic ice dispensing component then dispenses ice from the ice storage box through the ice outlet 43 and falls into the cup on the automatic cup delivery component 70. This completes the extraction and ice addition operations in coffee making.

[0050] In this embodiment, the ice-making component and the extraction component are combined with the automatic cup-feeding component 70. That is, through the automatic cup-feeding component 70, the ice-making component achieves linkage with the extraction process. It can realize the operation of dispensing ice first and taking ice then extracting, or extracting first and then adding ice. The automatic cup-feeding component 70 replaces the cumbersome operation of manually taking ice and feeding cups, simplifies the user steps, improves the convenience of use, and realizes "one-click" iced drink making.

[0051] In this embodiment, by adding an automatic cup-feeding component 70, the process sequence of "adding ice first and then coffee extract" or "adding coffee extract first and then ice" can be executed precisely. If you add ice before adding the coffee extract, the ice cubes should be placed in the cup first, followed by the hot coffee liquid poured over the ice cubes. This allows the ice cubes to instantly lock in the coffee aroma and prevents the hot coffee from oxidizing too quickly when directly exposed to the air.

[0052] Adding coffee extract before ice ensures that the coffee is extracted at the optimal temperature and then quickly combined with ice, preventing the coffee from over-cooling or losing flavor while waiting for ice.

[0053] This controlled, sequential operation is difficult to reliably achieve manually. In manual operation, users often leave the work surface during the extraction process, making it impossible to guarantee the timely addition of ice to the extract. Alternatively, adding ice beforehand requires multiple steps, making the process cumbersome and hindering the creation of "one-click" iced drinks. In this embodiment, by adding an automatic cup feeding component 70, the frequent hand movements of the user between the high-temperature area (extraction area) and the low-temperature area are reduced, thus lowering the risk of burns. Simultaneously, the user only needs to place an empty cup in the initial position, and the subsequent process is completed automatically, avoiding coffee spillage or ice spillage due to hasty operation, significantly improving the convenience and safety of use.

[0054] In one embodiment, the first heating component includes a thick-film heater. Thick-film heaters are a common and technologically mature type of heater in the prior art. They typically form a resistance heating circuit by printing and sintering a thick film (metal paste) onto the surface of an insulating substrate (such as stainless steel or ceramic tube), thereby achieving efficient conversion of electrical energy into heat energy. Thick-film heaters have a very compact structure, usually appearing as a slender metal tube, a coil, or a flat substrate. During heating, the water to be heated is directly heated as it flows through the channel with the thick-film resistor, eliminating the need for water storage or preheating, achieving "heating live water instantly." Thick-film heaters also possess precise temperature control capabilities. Combined with a highly sensitive temperature sensor and microprocessor, the heating power of the thick-film heater can be modulated at the millisecond level, achieving temperature control with a precision of ±1℃ or even higher.

[0055] In one embodiment, the first heating component 3 includes a thick-film heater, enabling it to achieve "live water heating, instant hot water," allowing it to quickly obtain hot water without waiting, and with precise temperature control. When the first heating component 3 supplies hot water to the extraction component 1 for extraction, it ensures the flavor of the extracted coffee.

[0056] In one embodiment, the first heating component 3 is a thick-film heater, which minimizes its impact on the temperature field inside the iced coffee machine. The thick-film heater's characteristics of "low thermal inertia" and "high transient response" ensure that it does not diffuse heat to the surrounding environment after installation, creating a safety barrier for surrounding precision structural components and allowing for flexible placement of components within the surrounding environment. In this iced coffee machine, the first heating component 3 uses a thick-film heater, ensuring no heat diffusion or thermal contamination to the cold water component and ice-making component 40. This allows the ice produced in the machine to be preserved for a longer period, preventing rapid melting, and ensures that the low-temperature cold water stored in the cold water tank 30 remains at a low temperature for a longer period, preventing rapid heating of the cold water in the cold water tank 30.

[0057] In one embodiment, the water source component 22 includes a water tank configured to store purified water that is ready for direct consumption. The purified water includes, but is not limited to, purified water or mineral water.

[0058] The water tank supplies water to the first heating component 3 and the extraction component 1.

[0059] In the above embodiments, by adding a water tank to the iced coffee machine, and the water tank supplying water to the first heating component 3 and the extraction component 1, the adaptability of the iced coffee machine is improved, so that the iced coffee machine can be installed in any location without having to use it with tap water or bottled water, reducing the pipeline connection between the iced coffee machine and the external water source, avoiding the dependence of the iced coffee machine on the external water source, and increasing the places where the iced coffee machine can be used.

[0060] In addition, adding a water tank to the iced coffee machine, which is filled with and stores drinkable clean water, can provide sufficient water pressure and a large water flow for coffee making or drinking water, making the water pressure stable and the water flow adjustable.

[0061] In one embodiment, such as Figure 2 As shown, inside the iced coffee machine, the water tank is located at the back of the machine, and the volume of the water tank is maximized to allow for the storage of more purified water, provided that the space inside the machine allows.

[0062] In one embodiment, the water tank is detachably connected to the body of the iced coffee machine. When adding water to the water tank, the water tank can be removed and moved to the water filling position to fill the water, making it highly versatile.

[0063] In one embodiment, the water tank is equipped with a water inlet, to which a water inlet pipe is connected. The other end of the water inlet pipe is connected to the purified water outlet of a filter connected to the tap water pipe. Water is replenished to the water tank through the tap water pipe. This replenishment method eliminates the need for frequent manual refilling by the user, resulting in a better user experience. The purified water obtained after filtration must meet the standards for direct drinking water. Of course, in some embodiments, the other end of the water inlet pipe connected to the water tank can also be directly connected to a bottled drinking water dispenser.

[0064] In one embodiment, a water level sensor is installed on the water tank to detect the water level in the tank. The water temperature sensor is electrically connected to the controller 50 in the water dispenser and coffee machine, which can realize water level alarm to remind the user to add water or automatically add water through the tap water source to ensure timely water replenishment.

[0065] In one embodiment, the water tank is also provided with a water level connector and a water level switch 23. The water level switch 23 has a high water level switch and a low water level switch. The water level connector triggers the high water level switch or the low water level switch to start, thereby turning off the automatic water replenishment operation to the water tank or starting the automatic water replenishment operation to the water tank, thus realizing the automatic water replenishment operation.

[0066] In one embodiment, the water source component 22 can be a structure that combines a municipal tap water pipe with a direct drinking filter. It supplies water through the municipal tap water and filters it through the direct drinking filter to obtain the required purified water, which directly supplies water to the extraction component 1 and the first heating component 3, thus avoiding the need for water replenishment.

[0067] In one embodiment, a first pipe 5 is connected to the water tank, and a second pipe 9 and a third pipe 7 are connected to the first pipe 5. The second pipe 9 is connected to the first heating component 3, and the third pipe 7 is connected to the extraction component 1. A second control valve 10 is provided on the second pipe 9, a third control valve 8 is provided on the third pipe 7, and a first pump body 6 is provided on the first pipe 5.

[0068] By setting up a second pipeline 9 and a third pipeline 7, as well as a second control valve 10 and a third control valve 8, the second control valve 10 and the third control valve 8 respectively control the on / off state of the second pipeline 9 and the third pipeline 7.

[0069] When the third control valve 8 is opened, the third pipeline 7 is connected, the first pump body 6 starts, and the purified water in the water tank is delivered to the extraction component 1, which can realize room temperature extraction. Room temperature extraction is a special case of low temperature extraction.

[0070] To improve the efficiency of room temperature extraction and shorten the extraction time, a pressure boosting valve or back pressure valve can be added to the third pipeline 7 to increase the pressure of the extraction water flowing into the extraction handle and accelerate the extraction.

[0071] When the second control valve 10 is opened, the second pipeline 9 is connected, the first pump body 6 is started, and the purified water in the water tank is delivered to the first heating component 3. After the first heating component 3 heats the water flow, it is supplied to the extraction component 1.

[0072] In one embodiment, the second control valve 10 is located in front of the first heating component 3, that is, the water flow first passes through the second control valve 10 and then through the first heating component 3.

[0073] In one embodiment, both the second control valve 10 and the third control valve 8 are two-way solenoid valves. The second control valve 10 and the third control valve 8 are electrically connected to the controller 50 of the iced coffee machine. The controller 50 realizes automatic control of the second control valve 10 and the third control valve 8, automatically controlling the on and off of the second control valve 10 and the third control valve 8, simplifying the control logic and control operation.

[0074] In one embodiment, a fourth pipe 11 is connected to the outlet of the first heating component 3, and the fourth pipe 11 is connected to the extraction component 1. A fourth control valve 12 is provided on the fourth pipe 11.

[0075] In one embodiment, the fourth control valve 12 is a two-way solenoid valve and is electrically connected to the controller 50, which controls the automatic opening and closing of the passage or the cutting off of the passage.

[0076] By setting up a fourth pipeline 11 and a fourth control valve 12, the fourth control valve 12 controls the opening and closing of the fourth pipeline 11.

[0077] The fourth control valve 12 is opened, and the hot water in the first heating component 3 enters the extraction component 1, realizing the hot extraction mode of the extraction component 1.

[0078] It is worth noting that the third control valve 8 and the fourth control valve 12 cannot be opened at the same time, that is, the water tank and the first heating component 3 cannot supply water to the extraction component 1 at the same time, that is, the extraction component 1 can only perform hot extraction, room temperature extraction or cold extraction at one time.

[0079] The first pump body 6 is installed on the first pipeline 5. When the first pump body 6 is closed, there is no water flow in the first pipeline 5. At this time, all valves and devices installed downstream of the first pipeline 5 are in the closed state along the water flow direction.

[0080] In one embodiment, the fourth control valve 12 is a two-way control valve that only controls the on / off state of the fourth pipeline 11 itself.

[0081] In one embodiment, the fourth control valve 12 is a three-way control valve, which is a three-position three-way solenoid valve. One outlet of the three-position three-way solenoid valve is connected to the extraction component 1, and the other outlet is connected to the atmosphere or to the wastewater box 19. When the extraction component 1 is blocked, the hot water in the first heating component is discharged through the three-way control valve to ensure the safety of the iced coffee machine.

[0082] In one embodiment, a pressure relief valve 20 is also connected to the outlet of the first pump body 6. The pressure relief valve 20 is connected to the wastewater box 19. When the internal pipeline of the iced coffee machine malfunctions, the water in the pipeline can be discharged through the first pump body 6 and the pressure relief valve 20 to ensure the safety of the iced coffee machine.

[0083] In one embodiment, a flow controller 21 is also provided on the first pipeline to control the flow rate in the first pipeline 5. In actual operation, the flow rate in the first pipeline 5 is adjusted as needed according to the effect of the water flow, thereby controlling the extraction of coffee flavor.

[0084] In one embodiment, the fourth control valve 12 is a solenoid valve, which is electrically connected to the controller 50 of the iced coffee machine to achieve automatic control.

[0085] In one embodiment, the extraction component 1 includes a brewing head. The brewing head includes an extraction outlet. In one embodiment, the first water outlet 241 and / or the second water outlet 242 of the drinking component 24 are arranged side by side with the extraction outlet, which improves the user experience and conforms to ergonomics.

[0086] In one embodiment, the iced coffee machine further includes a steam assembly. The steam assembly includes a steam nozzle 2 and a second heating assembly 4. The second heating assembly 4 is connected to the first heating assembly 3, and the first heating assembly 3 supplies hot water to the second heating assembly 4. The second heating assembly 4 further heats the hot water supplied by the first heating assembly 3 to obtain steam, which is then output through the steam nozzle 2. The first heating assembly 3 can simultaneously supply hot water to both the extraction assembly 1 and the second heating assembly 4.

[0087] In this embodiment, by adding a steam nozzle and a second heating component, the first heating component 3 supplies hot water to the second heating component 4, and the second heating component 4 further heats the hot water supplied by the first heating component 3 directly into steam, which is then discharged through the steam nozzle 2.

[0088] In this embodiment, during the steam acquisition process, the second heating component 4 utilizes the preheated hot water from the first heating component 3 for secondary heating. Compared to directly heating cold water into steam, this method requires a smaller heat energy difference, has higher heating efficiency, and a faster response speed. Furthermore, it yields a larger steam flow rate per unit time.

[0089] In this embodiment, the steam acquisition process is usually activated only when the user needs to froth milk. That is, the second heating component 4 is activated only when the user needs to froth milk and does not maintain a high temperature state at other times, which is more energy-efficient to a certain extent.

[0090] In this embodiment, since the second heating component 4 mainly processes soft water preheated by the first heating component 3 or water that has undergone preliminary heating, it reduces the rapid precipitation of calcium carbonate when directly heating cold water to a certain extent, which helps to delay the scale blockage problem in the steam pipeline and extend the machine maintenance cycle.

[0091] In this embodiment, the first heating component 3 is connected to the extraction component 1 and the second heating component 4. This means the first heating component 3 can simultaneously supply hot water to both the extraction component 1 and the second heating component 4, allowing the iced coffee machine to simultaneously perform hot coffee extraction and milk frothing. Specifically, by configuring the first heating component 3 and the second heating component 4, which cooperate but operate independently, the iced coffee machine allows the first heating component 3 to simultaneously supply high-temperature hot water to the extraction component 1 for coffee extraction, and simultaneously supply preheated hot water to the second heating component 4. The second heating component 4 then immediately reheats the hot water, rapidly converting it into high-temperature steam for output.

[0092] In this embodiment of the iced coffee machine, the water system with its dual heating components working in tandem achieves physical separation and time synchronization of the two core functions: coffee extraction and steam frothing. It offers at least the following technical advantages: Firstly, users can complete the coffee dispensing and milk frothing simultaneously without waiting for the temperature to change.

[0093] Secondly, users no longer need to wait for the cold water to heat up and generate steam after extraction before frothing the milk. This iced coffee machine optimizes the traditional sequential process of "extracting, waiting, then frothing the milk" into a parallel process of "extraction and frothing simultaneously," making the entire operation smoother and more seamless. Furthermore, this parallel operation eliminates the long waiting period for steam to heat up, allowing users to complete the operation in one go and providing a better experience.

[0094] Thirdly, because extraction and milk frothing can be completed simultaneously, the espresso produced does not require waiting for the milk to foam in the cup, avoiding the problems of coffee oils dissipating, temperature dropping, and flavor oxidation and souring caused by prolonged exposure to air. When the milk foam is fully frothed, the coffee is still in its optimal drinking state, ensuring the final taste of the specialty coffee.

[0095] Fourth, when multiple cups of coffee need to be made consecutively, the coffee-making operation of extracting and frothing milk in parallel can continuously and stably provide extraction water and steam without the need for waiting time between each brewing cycle. This significantly shortens the total time for continuous brewing, meets the needs of large families or small gatherings, improves the adaptability of this iced coffee machine, and expands the usage scenarios of this coffee machine.

[0096] In addition, in this embodiment, by setting a first heating component 3, a second heating component 4 and a steam nozzle 2, and the first heating component 3 supplies hot water to the second heating component 4, the second heating component 4 further heats the hot water supplied by the first heating component 3 directly into steam and discharges it through the steam nozzle 2. The water source component 22 supplies water to the first heating component 3 and the extraction component 1 at the same time, which can also realize room temperature extraction and the operation of room temperature extraction and steam milk frothing can be carried out simultaneously. The water supply logic is clear, reducing complex valve switching and redundant pipeline layout, and reducing the risk of water leakage and failure.

[0097] The iced coffee machine in this embodiment, by introducing a series-connected collaborative working mode of dual heating components, precisely solves the problems of low efficiency and fragmented processes in traditional coffee machines when making specialty coffees. This iced coffee machine provides the core function of simultaneous extraction and milk frothing, and can also simultaneously perform room-temperature extraction by the extraction component 1 and steam output from the steam nozzle. By integrating multiple functions into a single device, the iced coffee machine achieves a good balance in terms of compact structure, cost control, energy efficiency, and user experience.

[0098] In one embodiment, a fifth pipe 13 is connected to the outlet of the first heating component 3, the fifth pipe 13 is connected to the second heating component 4, and a fifth control valve 14 is provided on the fifth pipe 13.

[0099] In one embodiment, the fifth control valve 14 is a two-way solenoid valve, and both are electrically connected to the controller 50, which controls the automatic opening and closing of the passage or the cutting off of the passage.

[0100] By setting a fifth pipeline 13 and a fifth control valve 14, the fifth control valve 14 controls the opening and closing of the fifth pipeline 13.

[0101] When the fifth control valve 14 is opened, the hot water in the first heating component 3 enters the second heating component 4. The second heating component 4 continues to heat the hot water to obtain steam. The steam is output from the steam nozzle 2, which can complete the operation of frothing milk.

[0102] When the fourth control valve 12 and the fifth control valve 14 are opened simultaneously, the hot water in the first heating component 3 can enter the extraction component 1 and the second heating component 4 at the same time, which can realize the simultaneous hot extraction of coffee and steam frothing of milk.

[0103] It is worth noting that the third control valve 8 and the fourth control valve 12 cannot be opened simultaneously, meaning that the water tank and the first heating component 3 cannot supply water to the extraction component 1 at the same time. However, the third control valve 8 can be opened simultaneously with the second control valve 10 and the fifth control valve 14, and the second control valve 10, the fourth control valve 12, and the fifth control valve 14 can all be opened at the same time, as can the second control valve 10 and the fourth control valve 12.

[0104] In one embodiment, the outlet of the fifth control valve 14 is connected to the inlet of the second heating component 4, which can vent the steam in the second heating component 4, reduce water retention in the second heating component 4, and reduce scale deposition.

[0105] In one embodiment, the fifth control valve 14 is a solenoid valve, which is electrically connected to the controller 50 of the coffee machine to achieve automatic control.

[0106] In one embodiment, the iced coffee machine further includes a water dispensing component 24, wherein the first heating component 3 supplies heated water to the water dispensing component 24, and the water dispensing component 24 is positioned to provide a function for receiving hot water.

[0107] In one embodiment, the first heating component 3 supplies hot water to the drinking component. Simultaneously, when the hot water is output from the outlet of the first heating component 3, it can also enter the extraction component 1, or simultaneously enter the second heating component 4. That is, when hot water is received at the drinking component 24, hot extraction can also be performed simultaneously at the extraction component 1, or simultaneously, milk foam can be generated at the steam nozzle 2.

[0108] This iced coffee machine can prepare coffee and dispense hot water simultaneously, which not only increases the functionality of the iced coffee machine but also increases its parallel operation, thereby improving its working efficiency.

[0109] In one embodiment, the second heating component 4 is a thick-film heater. The second heating component 4, being a thick-film heater, can rapidly heat the hot water provided by the first heating component 3 to 120°C, obtaining high-temperature steam, shortening the steam acquisition time, and accelerating the coffee making process. The second heating component 4, being a thick-film heater, leverages the "instant heating" characteristic of thick-film heaters to quickly obtain a large flow of steam, improving the quality of milk frothing.

[0110] Both the first heating element 3 and the second heating element 4 are thick film heaters, which minimizes the impact of the first heating element 3 and the second heating element 4 on the temperature field inside the coffee machine and shortens the melting time of the ice stored inside the coffee machine.

[0111] In one embodiment, the drinking water assembly 24 includes a first water outlet 241 and a second water outlet 242. A sixth pipe 15 is also connected to the outlet of the first heating assembly 3. The sixth pipe 15 is connected to the first water outlet 241 of the drinking water assembly 24, and a sixth control valve 16 is provided on the sixth pipe 15.

[0112] In this embodiment, the sixth control valve 16 is a two-way solenoid valve and is electrically connected to the controller 50. The controller 50 controls the automatic opening or closing of the sixth pipeline 15.

[0113] In this embodiment, the first outlet 241 is connected to the outlet of the first heating component 3 via the sixth pipe 15, meaning the first outlet 241 is used to receive hot water. During operation, the second control valve 10 and the sixth control valve 16 are activated, starting the first pump body 6 and the first heating component 3. Water in the tank is heated by the first heating component 3, then flows through the sixth pipe 15 and the sixth control valve 16, finally exiting through the first outlet 241, where hot water is received.

[0114] Hot water can be supplied and coffee hot extraction can be performed simultaneously, hot water can be supplied and steam frothing of milk can be performed simultaneously, hot water can be supplied and coffee hot extraction and steam frothing of milk can be performed simultaneously, and hot water can be supplied and coffee can be extracted at room temperature by extraction component 1 simultaneously.

[0115] In one embodiment, a seventh pipe 25 is connected to the second water outlet 242 of the drinking water assembly 24, and the seventh pipe 25 is connected to the water source assembly 22. A second pump body 27 is provided on the seventh pipe 25, and a seventh control valve 26 is also provided on the seventh pipe 25. The outlet of the seventh control valve 26 is connected to the inlet of the second pump body 27.

[0116] In this embodiment, the seventh control valve 26 is a two-way solenoid valve and is electrically connected to the controller 50. The controller 50 controls the automatic opening or closing of the seventh pipeline 25.

[0117] The second pump body 27 starts, and simultaneously the seventh control valve 26 is activated, enabling the drinking water assembly 24 to receive room temperature water. The room temperature water is output from the second outlet 242.

[0118] When room temperature water is connected to the second outlet 242, hot water can be simultaneously connected to the first outlet 241. Simultaneously, hot or room temperature coffee extraction can also be performed, as well as steam frothing of milk.

[0119] In one embodiment, the iced coffee machine further includes a cold water assembly, which includes a cold water tank 30 configured to store low-temperature cold water. The cold water tank 30 is configured to supply low-temperature cold water to the drinking assembly 24 and the extraction assembly 1.

[0120] The cold water tank 30 is connected to an eighth pipe 31, which is connected to the inlet of the second pump body 27, and an eighth control valve 32 is provided on the eighth pipe 31.

[0121] The cold water tank 30 is also connected to a ninth pipe 33, which is connected to a two-inlet-one-outlet control valve 28. One inlet of the two-inlet-one-outlet control valve 28 is connected to the ninth pipe 33, and the other inlet of the two-inlet-one-outlet control valve 28 is connected to the water tank. The outlet of the two-inlet-one-outlet control valve 28 supplies water to the extraction component 1 and the first heating component 3. The outlet of the two-inlet-one-outlet control valve 28 is connected to the inlet of the first pump body 6.

[0122] In this embodiment, the eighth control valve 32 is a two-way solenoid valve and is electrically connected to the controller 50. The controller 50 controls the automatic opening or closing of the eighth pipeline 31.

[0123] In this embodiment, the eighth control valve 32 is a two-way solenoid valve and is electrically connected to the controller 50. The controller 50 controls the automatic opening or closing of the eighth pipeline 31.

[0124] In this embodiment, the two-inlet-one-outlet control valve 28 is a solenoid valve and is electrically connected to the controller 50. The controller 50 automatically controls the outlet of the two-inlet-one-outlet control valve 28 to automatically connect with one of its inlets as needed. The second pump body 27 starts, and the low-temperature cold water in the cold water tank 30 is delivered to the second outlet 242 of the drinking water assembly 24. Low-temperature cold water can be collected at the second outlet 242 of the drinking water assembly 24.

[0125] When cold water is connected to the second outlet 242, the first pump body 6 can work normally, enabling coffee extraction, steaming of baby bottles, or connection of hot water.

[0126] The passage from the cold water tank 30 to the outlet of the two-inlet-one-outlet control valve 28 is opened, and the first pump body 6 is started. At this time, the first pump body 6 delivers low-temperature cold water. After passing through the first pump body 6, the low-temperature cold water passes through the third control valve 8 and enters the extraction component 1, enabling the extraction component 1 to perform cold extraction mode. Compared with hot extraction, cold extraction can produce coffee with different flavor profiles, improving the adaptability of the iced coffee machine.

[0127] When the extraction component 1 is performing cold extraction, the action of adding hot water or steaming to froth milk cannot be performed simultaneously.

[0128] In this embodiment, the cold water component includes a cold water tank 30, which is configured to store low-temperature cold water. The low-temperature cold water can be added externally or a refrigeration component can be installed inside the iced coffee machine to prepare low-temperature cold water and store it in the cold water tank 30.

[0129] In one embodiment, the cooling component may be a semiconductor thermoelectric cooler, which has advantages such as small size, low noise, and no vibration.

[0130] In one embodiment, the refrigeration component can be a compressor refrigeration system, which includes an ice maker, a compressor, a condenser, a capillary tube, and an evaporator, connected sequentially. The refrigerant, driven by the compressor, circulates between the condenser, capillary tube, and evaporator. The heat exchange tubes on the evaporator are bent to form an evaporation head, which is inserted into a cold water tank 30 to cool the water flow within, thus obtaining low-temperature chilled water. This compressor refrigeration system provides high efficiency and rapid chilled water preparation.

[0131] In one embodiment, the ice-making assembly 40 is connected to the cold water tank 30, the ice-making assembly 40 is configured to provide low-temperature cold water to the cold water tank 30, and the cold water tank 30 is configured to provide ice-making water and / or water for preparing low-temperature cold water to the ice-making assembly 40.

[0132] Adding an ice-making component 40 allows for the collection of ice cubes, which can then be added to coffee or other beverages to create a wider variety of flavored drinks, thus enhancing the functionality of this iced coffee machine.

[0133] During the ice-making process, the ice-making component 40 simultaneously obtains low-temperature chilled water and delivers it to the cold water tank 30 for storage. After the water temperature in the cold water tank 30 rises, the water can be returned to the ice-making component 40 for cooling, thus obtaining low-temperature chilled water again. The ice-making component 40 can produce both ice and low-temperature chilled water.

[0134] In one embodiment, the ice-making assembly 40 includes an ice-making mechanism and an ice storage box, wherein the ice blocks prepared by the ice-making mechanism are stored in the ice storage box.

[0135] In one embodiment, the ice-making mechanism includes an ice-making box 44, a compressor 45, a condenser 47, a capillary tube 48, and an evaporator 49, which are connected sequentially. The refrigerant, driven by the compressor 45, circulates between the condenser 47, the capillary tube 48, and the evaporator 49. The heat exchange tubes on the evaporator 49 are bent to form an evaporation head. This evaporation head is inserted into the ice-making box 44, which stores water for ice making. The water in the ice-making box 44 comes into contact with the evaporation head, forming ice blocks. The ice blocks then detach from the evaporation head and are stored in an ice storage box 41. In this embodiment, the ice-making system, using a compressor, results in rapid ice making, a large ice production capacity, high ice-making efficiency, and low energy consumption.

[0136] In one implementation, a defrosting valve 46 is connected to the refrigerant outlet of the compressor 45. The outlet of the defrosting valve 46 is directly connected to the inlet of the evaporator 49, forming a refrigerant passage for defrosting the evaporator head. When ice needs to be removed from the evaporator head, the refrigerant in the compressor 45 enters the evaporator 49 directly through the defrosting valve 46, causing the evaporator head to heat up rapidly. At this time, the ice surface in contact with the evaporator head senses this temperature increase the fastest, causing the ice on the evaporator head to detach. The ice detached from the evaporator head first enters the ice-making box 44, where it forms an ice-water mixture with the cold water inside. Then, the ice is separated from the ice-making box 44 and stored in the ice storage box 41.

[0137] In one embodiment, an ice dispensing component is also provided inside the ice storage box. The ice dispensing component includes an ice outlet 43 and a spiral shaft 42 for conveying ice. The spiral shaft 42 is inclined, and the ice outlet 43 is connected to the high end of the spiral shaft 42. The bottom end of the spiral shaft 42 is connected to the ice storage box 41. The spiral shaft 42 transports the ice from the bottom end to the high end and discharges it through the ice outlet 43, thereby realizing automatic ice dispensing.

[0138] In one embodiment, the spiral shaft 42 is disposed inside the ice storage box 41, and the ice storage box 41 can be adapted to the tilted state of the spiral shaft 42.

[0139] In one embodiment, the ice outlet 43 and the outlet of the extraction component 1 are arranged side by side on the body of the water dispenser and coffee maker for ease of use and ergonomic design. In another embodiment, a certain distance needs to be provided between the ice outlet 43 and the outlet of the extraction component 1 to allow for simultaneous coffee extraction and ice dispensing.

[0140] In one embodiment, after the ice-making mechanism prepares ice, the ice that detaches from the evaporator head first enters the ice-making box 44 and forms an ice-water mixture with the cold water in the ice-making box 44. Then, the ice is separated from the ice-making box 44 and stored in the ice storage box 41, while the low-temperature cold water is stored in the cold water tank 30.

[0141] A separation box is installed at the bottom of the ice-making box 44. When the ice cubes on the evaporator head detach from the evaporator head and fall into the ice-making box 44, the ice-making box 44 is flipped so that the ice-water mixture in the ice-making box 44 enters the separation box. The bottom of the separation box is provided with a separation hole. Low-temperature cold water is discharged through the separation hole and introduced into the cold water tank 30 through a pipe. The ice cubes temporarily left in the separation box are sent into the ice cube storage box 41.

[0142] Specifically, a scraper is installed on the rotating shaft that drives the ice-making box 44 to rotate, and the scraper is located above or diagonally above the ice-making box 44. After the ice-making box 44 flips over, the ice-water mixture enters the separation box. As the ice-making box 44 flips back to its original position, the scraper scrapes the ice cubes in the separation box into the ice cube storage box 41.

[0143] In one embodiment, if ice making is not required and only low-temperature cold water needs to be prepared, the evaporator head on the evaporator only cools the water flow in the preparation box, and it is not necessary to cool it to below zero degrees Celsius. A large amount of low-temperature cold water is quickly obtained, and then the low-temperature cold water is transported and stored in the cold water tank 30 by flipping the preparation box.

[0144] In one embodiment, the cold water tank 30 is an insulated tank, which has the function of keeping the low-temperature cold water in the cold water tank 30 at a low temperature for a relatively long period of time.

[0145] In one embodiment, the inlet of the cold water tank 30 is connected to the ice-making assembly 40. That is, the low-temperature cold water obtained during ice making is delivered to the cold water tank 30. As mentioned earlier, a separation box is installed at the bottom of the ice-making box 44. When ice blocks detach from the evaporator head and fall into the ice-making box 44, the ice-water mixture inside the ice-making box 44 is flipped, causing it to enter the separation box. The bottom of the separation box has a separation hole through which the low-temperature cold water is discharged and introduced into the cold water tank 30 through a pipe. In this embodiment, low-temperature cold water is obtained during the ice-making process, improving refrigeration efficiency and resulting in a large volume of low-temperature cold water.

[0146] In one embodiment, one outlet of the cold water tank 30 is connected to the ice-making assembly 40. In some locations, such as when the ambient temperature is high or ice-making has not been carried out for a long time and no low-temperature cold water is replenished to the cold water tank 30, the temperature of the low-temperature cold water originally stored in the cold water tank 30 will rise. At this time, by connecting the outlet of the cold water tank 30 to the ice-making assembly 40, the cold water in the cold water tank 30 that has been heated or is about to be heated is transported to the ice-making assembly 40, whereby the ice-making assembly 40 obtains low-temperature cold water again, and then the low-temperature cold water is stored back in the cold water tank 30. In this embodiment, the heated cold water in the cold water tank 30 enters the ice-making component 40. If it is not necessary to make new ice cubes at this time, the ice-making component 40 only cools the water flow in the ice-making box 44 to the required temperature, such as 0-5°C. At this time, it is not necessary to cool the water flow in the ice-making box 44 to below zero degrees, that is, it is not necessary to make ice cubes. This avoids the problem of too many ice cubes not being able to be contained in the ice cube storage box 41, and also avoids the waste of refrigeration energy.

[0147] In one embodiment, the cold water tank 30 is connected to the water source component 22 and is also connected to the ice-making component 40. The cold water tank 30 is used to receive the low-temperature cold water obtained by the ice-making component 40 and to supply ice-making water to the ice-making component 40.

[0148] In this embodiment, the cold water tank 30 is used to receive the low-temperature cold water obtained by the ice-making component 40. That is, the water inlet of the cold water tank 30 is connected to the ice-making component 40. Specifically, the water inlet of the cold water tank 30 is connected to the ice storage box 41. The ice stored in the ice storage box 41 will melt as the temperature rises or the storage time is too long. At this time, the water can be transported to the cold water tank 30 for use.

[0149] In this embodiment, the cold water tank 30 is connected to the water source component 22, that is, one outlet of the water tank is connected to one inlet of the cold water tank 30, and the room temperature water in the water tank enters the cold water tank 30.

[0150] In this embodiment, the cold water tank 30 supplies ice-making water to the ice-making assembly 40. The room temperature water in the water tank enters the cold water tank 30, or the original low temperature cold water in the cold water tank 30 is transported to the ice-making assembly 40 through the outlet of the cold water tank 30 to prepare ice blocks and / or prepare low temperature cold water.

[0151] In one embodiment, the outlet of the water tank is connected to the inlet of the cold water tank 30, enabling the transfer of room temperature water from the water tank to the cold water tank 30. The room temperature water then flows through the outlet of the cold water tank 30 to the refrigeration unit for cooling, producing low-temperature cold water. This low-temperature cold water then re-enters the cold water tank 30. When a large amount of room temperature water is added to the cold water tank 30 at once, the water needs to be transferred multiple times through a water pipe to the refrigeration unit for multiple cooling cycles until the desired temperature of the cold water is obtained.

[0152] In one embodiment, the first heating component 3 is further connected to a tenth pipe 18, which communicates with the ice-making component 40 to provide hot water to the ice-making component 40. By supplying hot water to the ice-making component 40 through the first heating component 3, the ice-making component 40 can be cleaned and disinfected at high temperature.

[0153] A one-in-two-out control valve 17 is installed on the sixth pipeline 15. The inlet of the one-in-two-out control valve 17 is connected to the outlet of the sixth control valve 16, and the two outlets of the one-in-two-out control valve 17 are respectively connected to the first water outlet 241 and the ice-making component 40.

[0154] In one embodiment, the one-in-two-out control valve 17 is a solenoid valve and is electrically connected to the controller 50. The controller 50 automatically controls the one-in-two-out control valve 17 to open the passage from the first heating component 3 to the drinking water component or the passage from the first heating component 3 to the ice-making component 40 as needed.

[0155] In one embodiment, the iced coffee machine further includes a grinding assembly 60. The grinding assembly 60 includes a bean hopper 61, a grinding component, and a dispensing component. The dispensing component includes a dispensing outlet 64, which is connected to the grinding component. The grinding component is connected to the bean hopper 61. The grinding component includes a fixed blade 65 and a movable blade 651, and the gap 66 between the fixed blade 65 and the movable blade 651 is adjustable.

[0156] In this embodiment, a grinding component 60 is added to the coffee machine. The grinding component 60 grinds coffee beans into coffee powder, which is then placed into an extraction container, such as a portafilter. The portafilter is then positioned in the extraction component 1 for extraction to obtain concentrated coffee. In this embodiment, the grinding component 60 in the coffee machine enables the machine to not only extract coffee but also grind coffee powder, obtaining freshly ground coffee powder for immediate extraction. This shortens the storage time after grinding, improves the taste of the brewed coffee, and meets people's growing appreciation and demands for coffee.

[0157] In this embodiment, the gap 66 between the fixed cutter head 65 and the moving cutter head 651 is adjustable, which means that the fineness of the coffee powder obtained by grinding can be adjusted to adapt to different coffee powder grinding requirements and different users' requirements for coffee taste, thus having good adaptability.

[0158] In one embodiment, the grinding assembly includes a fixed blade head 65 and a movable blade head 651, as well as a fixed blade holder 67 and a movable blade holder. The fixed blade head 65 is fixedly installed on the fixed blade holder 67, and the movable blade head 651 is rotatably installed on the movable blade holder. After installation, the fixed blade head 65 is sleeved outside the movable blade head 651. The gap 66 between the fixed blade head 65 and the movable blade head 651 is the grinding area. Coffee enters the grinding area, and the movable blade head 651 rotates relative to the fixed blade head 65 to grind the coffee in the grinding area. The obtained coffee powder is discharged by the powder dispensing assembly.

[0159] In one embodiment, the fixed cutter head 65 and the movable cutter head 651 are coaxially arranged. A drive assembly 62 is connected to the movable cutter head 651. The drive assembly 62, such as a drive motor, is used to drive the movable cutter head 651 to rotate around its own axis, so as to achieve relative rotation with the fixed cutter head 65 and to grind the coffee beans located in the gap 66 between the fixed cutter head 65 and the movable cutter head 651.

[0160] In one embodiment, the drive assembly 62 is fixedly installed with the moving blade holder, and the moving blade holder is fixedly installed with the coffee machine body.

[0161] In one embodiment, a gap adjustment device is connected to the fixed blade holder 67 to adjust the size of the gap 66 between the fixed blade head 65 and the moving blade head 651. Generally, the position of the fixed blade head 65 is adjusted along the axial direction of the moving blade head 651. The gap adjustment device moves the fixed blade holder 67 and the fixed blade head 65, so that the fixed blade head 65 is away from the moving blade head 651. This increases the gap 66 between the fixed blade head 65 and the moving blade head 651, allowing for coarser coffee powder to be ground. Conversely, if the fixed blade head 65 is moved closer to the moving blade head 651, the gap 66 between the fixed blade head 65 and the moving blade head 651 decreases, allowing for finer coffee powder to be ground.

[0162] In one embodiment, as shown in the figure, the gap adjustment device includes a transmission threaded sleeve 69 connected to a fixed tool holder 67. The inner wall of the transmission threaded sleeve 69 is threadedly connected to the fixed tool holder 67. A transmission driven gear disk is fixedly sleeved on the outer wall of the transmission threaded sleeve 69. The axial direction of the transmission driven gear disk coincides with the axial direction of the fixed tool head 65. An adjustment ring 68 with a driving gear disk is meshed on the transmission driven gear disk. The driving gear disk meshes with the transmission driven gear disk. By rotating the adjustment ring 68, the transmission threaded sleeve 69 can be driven to rotate. The transmission threaded sleeve 69 drives the fixed tool holder to move axially, that is, drives the fixed tool head 65 to move along its own axial direction.

[0163] In one embodiment, the coffee dispensing assembly includes a powder guiding channel 63 and a powder dispensing port 64. One end of the powder guiding channel 63 is connected to the grinding area, and the other end is connected to the powder dispensing port 64. During coffee bean grinding, an extraction portafilter is installed at the powder dispensing port 64. The coffee powder obtained after grinding by the grinding assembly enters the portafilter bowl on the extraction portafilter through the powder guiding channel 63 and the powder dispensing port 64. After grinding is completed, the extraction portafilter containing the coffee powder is installed on the extraction assembly 1 to perform coffee extraction.

[0164] In one embodiment, the powder outlet 64 is located on one side of the extraction component 1 for easy powder collection. Of course, depending on layout requirements, the powder outlet 64 can also be located in other positions, such as... Figure 2 As shown, the powder outlet 64 is located behind the extraction component 1, which helps to reduce the size of the coffee machine in the left and right width direction and achieve miniaturization of the coffee machine.

[0165] In one embodiment, the automatic cup feeding assembly 70 includes a cup holder 71 for placing the cup. The cup holder 71 is sleeved on a drive threaded rod 73, and the cup holder 71 is threadedly connected to the drive threaded rod 73.
