Description

Technical Field

[0001] The present invention relates to the technical field of water purification, and in particular to a beverage machine. Background Art

[0002] As living standards improve, the technology of beverage machines is constantly improving.

[0003] Existing beverage machines tend to be multifunctional, which can not only provide purified water, but also heat or cool the purified water to provide hot water and cold water respectively.

[0004] However, due to the consideration of small space and simple control logic, the water production module in the current beverage machine is usually large-flow, that is, the daily water production is greater than or equal to 400 gallons, so that no matter hot water, cold water or room temperature water is needed, the water production module can be directly started and used immediately. However, the disadvantage of the large-flow water production module is that the manufacturing cost and the use cost are relatively high, which cannot meet the needs of users. Summary of the invention

[0005] In order to at least partially solve the problems existing in the prior art, some embodiments of the present invention provide a beverage machine, which has a water inlet and a water outlet, and includes: a small-flux water purification device, the small-flux water purification device having a clean water outlet and a raw water inlet connected to the water inlet; a normal temperature water pipeline connected between the clean water outlet and the water outlet, on which a clean water solenoid valve and a clean water tank are sequentially arranged; a hot water pipeline connected between the clean water outlet and the water outlet, on which a hot water solenoid valve and a hot tank are sequentially arranged; a cold water pipeline connected between the clean water outlet and the water outlet, on which a cold water solenoid valve and a cold tank are sequentially arranged; and a control device, the control device is used to control the clean water solenoid valve to open and control the small-flux water purification device to work when there is a lack of water in the clean water tank; control the hot water solenoid valve to open and control the small-flux water purification device to work when there is a lack of water in the hot tank; and control the cold water solenoid valve to open and control the small-flux water purification device to work when there is a lack of water in the cold tank.

[0006] In the above technical solution, when the user needs normal temperature water, it can be directly provided from the clean water tank to the water outlet; when the user needs hot water at a higher temperature, it can be directly provided from the hot tank to the water outlet; when the user needs cold water at a lower temperature, it can be directly provided from the cold tank to the water outlet. Therefore, the user has greater freedom of choice and can meet more needs of the user. In addition, since the beverage machine is provided with a clean water tank, a hot tank, and a cold tank, all of which have water storage functions and corresponding solenoid valves are provided upstream thereof, this solution of outputting hot water at multiple temperatures is particularly suitable for small-flux water purification devices. The use of a small-flux water purification device can significantly reduce the manufacturing cost and the cost of replacing the filter element by the user. In addition, when outputting cold water, hot water, and normal temperature water, they can not interfere with each other, and the maximum amount of water that can be obtained by these three types of water can reach the maximum capacity of the container storing them, and the user experience is better.

[0007] Exemplarily, a first water pump is arranged on the normal temperature water pipeline and downstream of the clean water tank, and a second water pump is arranged on the hot tank pipeline and downstream of the hot tank. At least one of the first water pump and the second water pump is a flow-adjustable water pump. The beverage machine also includes a mixing water pipeline. The water inlet of the mixing water pipeline is connected to the normal temperature water pipeline downstream of the first water pump, and the water outlet of the mixing water pipeline is connected to the hot water pipeline downstream of the second water pump. A mixing water solenoid valve is arranged on the mixing water pipeline. The control device is used to control the switch of the mixing water solenoid valve and the flow of the flow-adjustable water pump according to the desired water intake temperature and the water temperature in the hot tank.

[0008] In the above technical solution, the control device is used to control the switch of the water mixing solenoid valve and the flow rate of the flow-adjustable water pump according to the expected water intake temperature and the water temperature in the hot tank, so as to ensure that the output hot water temperature meets the expected water intake temperature and can meet the user's needs for various water temperatures between room temperature and the water temperature in the hot tank. Exemplarily, a heating body is also provided on the hot water pipeline, and the heating body is provided downstream of the water outlet of the second water pump and the water mixing pipeline. The control device is also used to control the heating power of the heating body according to the expected water intake temperature, the water temperature in the hot tank, and the flow rates of the first water pump and the second water pump.

[0009] Exemplarily, the beverage machine further includes: a first liquid level sensor for detecting the level of clean water in the clean water tank, and the control device for determining whether the clean water tank is short of water according to the level of clean water. In the above technical solution, the first liquid level sensor can replenish the clean water tank in time when it is short of water, and prevent overflow caused by excessive replenishment.

[0010] Exemplarily, the beverage machine further includes: a second liquid level sensor for detecting the hot water level in the hot tank, and the control device is used to determine whether the hot tank is short of water according to the hot water level. In the above technical solution, the second liquid level sensor can replenish the hot tank in time when it is short of water, and prevent overflow caused by excessive replenishment.

[0011] Exemplarily, the beverage machine further includes: a third liquid level sensor for detecting the cold water level in the cold tank, and the control device is used to determine whether the cold tank is short of water according to the cold water level. In the above technical solution, the third liquid level sensor can replenish the cold tank in time when it is short of water, and prevent overflow caused by excessive replenishment.

[0012] Exemplarily, the beverage machine further includes an ice making module, an ice delivery module and an ice storage box, wherein the ice making module is connected to the cold tank and is used to receive water from the cold tank and make ice cubes, and the ice delivery module is used to deliver the ice cubes to the ice storage box. In the above technical solution, such a beverage machine can also provide ice cubes for users, and using the cold water in the cold tank to make ice can shorten the waiting time of users.

[0013] Exemplarily, the beverage machine further includes a prompt module and an ice quantity detector for detecting the current ice quantity information in the ice storage box. The control device is used to control the ice delivery module to deliver ice cubes to the ice storage box and time the ice storage time when the ice making module completes ice making, and control the prompt module to issue a prompt message about the ice cubes being not fresh when the ice storage time reaches a preset threshold and it is determined according to the current ice quantity information that there are still ice cubes in the ice storage box. By setting a preset threshold for the ice storage time, the user can be reminded in time when the ice cubes are not fresh, which can ensure the freshness of the ice cubes provided to the user to a certain extent, and can also prevent a large amount of ice cubes from freezing, thereby improving the user experience.

[0014] Exemplarily, the beverage machine further includes an input module, the input module is used to receive the target ice quantity input by the user, generate and send the target ice quantity information to the control device, the target ice quantity is n times the single ice making quantity of the ice making module, n is a positive integer, wherein the control device controls the ice delivery module to deliver ice cubes to the ice storage box and counts the ice storage time when the ice making module completes ice making, including the following operations: controlling the ice delivery module to deliver the ice cubes of the single ice making quantity to the ice storage box each time the ice making module completes ice making; and when it is determined according to the current ice quantity information that the ice storage box is emptied, recounting the ice storage time from the next time the ice making module completes ice making. This setting allows the user to obtain the required number of ice cubes with one input, simplifying the operation. It is also possible to deliver the ice cubes to the ice storage box in time through the ice delivery module when the ice making is completed, reducing the waiting time of the user. And when the number of ice cubes required by the user is greater than the single ice making quantity and the device needs to make ice multiple times, it is avoided that the first batch of ice cubes in this ice making task are not fresh and contaminate the subsequent ice cubes, so as to always provide the user with the freshest ice cubes.

[0015] Exemplarily, the target ice quantity is less than the maximum ice storage capacity of the ice storage box, so as to ensure that the target ice quantity is appropriate and ice cubes will not overflow from the ice storage box, causing waste or damaging the device.

[0016] Exemplarily, the control device is further configured to control the prompt module to issue a prompt message about emptying the ice storage box when receiving the target ice quantity information from the input module, if the ice storage box is not emptied according to the current ice quantity information. Ice making is performed after the user has emptied the ice storage box, also to avoid ice cubes overflowing from the ice storage box, causing waste or damaging the device.

[0017] Exemplarily, the control device is also used to: when it is determined according to the current ice quantity information that there is no ice in the ice storage box and the ice making module stops making ice, the control prompt module sends a prompt message about the lack of ice at this time. By setting the ice quantity detection function, it is convenient for the user to know the ice information and make ice in time; on the other hand, if the ice information prompted by the machine is inconsistent with the actual situation, the user can be reminded of the equipment failure and handle it in time to avoid the beverage machine working in abnormal conditions for a long time.

[0018] Exemplarily, the beverage machine further includes an installation position detector for detecting whether the ice storage box is installed in place, wherein the control device controls the ice delivery module to deliver ice cubes to the ice storage box when the ice storage box is installed in place. This can prevent the ice delivery module from delivering ice cubes to the ice storage box when the ice storage box is not placed or the ice storage box is tilted, thereby avoiding the occurrence of ice cubes falling and wasting.

[0019] Exemplarily, the control device is also used to: when the ice making module completes ice making each time and determines that the ice storage box is not installed in place, control the ice making module to stop making ice. The above solution can make the size of ice cubes within a controllable range, facilitate the storage and transportation of ice cubes, reduce energy waste, avoid damage to the beverage machine, and improve user experience.

[0020] Exemplarily, the ice-making module includes: one or more ice-making heads; a refrigeration assembly, the refrigeration assembly is used to cool the ice-making heads; and an ice-making water storage box, the ice-making water storage box has an ice-making position, and when the ice-making water storage box is in the ice-making position, the ice-making head extends into the ice-making water storage box to form ice cubes on the ice-making head. The above technical solution facilitates the separation of ice cubes from the ice-making head, thereby simplifying the control logic. In addition, the ice-making water storage box can be easily refilled with water.

[0021] Exemplarily, the control device is used to: control the working time of the refrigeration component so that there is water left in the ice making water storage box each time ice making is completed. This can prevent all the water from freezing into ice cubes, causing the ice making head and the ice making water storage box to freeze completely, and can also prevent the ice making water storage box from being unable to leave the ice making position and the ice cubes being too large to be transported by the ice delivery module.

[0022] Exemplarily, the ice delivery module includes: an ice delivery track, an ice receiving portion of the ice delivery track is located directly below the ice making head, and an ice output portion of the ice delivery track is located directly above the ice storage box; and a driver, the ice making water storage box can be moved between an ice making position and a demoulding position under the action of the driver, wherein the ice making water storage box is located outside the ice falling path between the ice making head and the ice receiving portion when in the demoulding position. This design allows the ice cubes to enter the ice receiving portion by gravity after being made, and the ice making water storage box can be immediately put into the next ice making operation after the ice cubes in the ice making head are emptied, thereby improving the ice making efficiency when the user needs a large amount of ice cubes, simplifying the structure of the beverage machine, reducing costs, and making it more reliable.

[0023] Exemplarily, the driver is used to drive the ice-making water storage box to rotate around a horizontal axis so that the ice-making water storage box moves between an ice-making position and a demoulding position. The above technical solution has a simple structure, low cost, and is more stable and reliable.

[0024] Exemplarily, at least the ice receiving portion of the ice transport track is provided with a first drainage hole, which is connected to the water inlet of the cold tank through a return pipe. After each ice making, there is water left in the ice making water storage box, and the first drainage hole and the return pipe can facilitate the return of this part of water to the cold tank, thereby recycling this part of water and avoiding waste of resources.

[0025] Exemplarily, a sterilization component is provided on the return line and / or in the cold tank. In the above technical solution, the provision of the sterilization component can prevent the growth of bacteria in the cold tank from affecting the freshness of ice cubes and cold water.

[0026] For example, the ice transport track is tilted downward along the direction of delivering the ice cube receiving part to the ice cube output part. In this way, ice cubes can slide from the ice cube receiving part of the ice transport track to the ice cube output part under the action of gravity, which can further simplify the structure of the product and reduce the cost.

[0027] Exemplarily, the control device is also used to: when the ice-making module completes ice-making, control the refrigeration component to reduce the intensity of refrigeration on the ice-making head so that the ice cubes can be separated from the ice-making head. The above technical solution can save energy, and can enable the ice-making module to quickly make ice and demold ice cubes, thereby improving user experience.

[0028] For example, a second drainage hole is provided at the bottom of the ice storage box, the beverage machine has a drainage end for communicating with the outside, and the second drainage hole is connected to the drainage end. In the above technical solution, the cleanliness of ice cubes can be ensured, and bacterial growth caused by accumulated water can be avoided, thereby preventing the shelf life of ice cubes from being further shortened.

[0029] Exemplarily, the cold tank is located below the ice delivery module. In the above technical solution, the cold tank is arranged below the ice delivery module, so that the residual ice water after ice making can flow back into the cold tank by gravity, saving resources and energy.

[0030] Exemplarily, the cold tank is located below the ice making water storage box. In the above technical solution, the cold tank is arranged below the ice making water storage box, so that the residual ice water after ice making can flow back into the cold tank by gravity, saving resources and energy.

[0031] Exemplarily, a third water pump is provided on the pipeline between the cold tank and the ice making module. In the above technical solution, the cold water in the cold tank is pumped to the refrigeration assembly by the water pump, and the approximate amount of the pumped cold water can be controlled. The cold water temperature is low, and the ice making speed is faster, which reduces the waiting time of users.

[0032] Exemplarily, the beverage machine further includes a bubble water module, which is connected between the cold tank and the water outlet, and is used to obtain purified water from the cold tank and make bubble water. In the above technical solution, the bubble water module is provided and cold water is provided from the cold tank to the bubble water module, so that the user can be provided with bubble water with a lower temperature, better taste and sufficient bubbles, thereby enriching the user experience.

[0033] Exemplarily, the bubble water module includes: a bubble water pipeline connected between the cold tank and the water outlet, on which a bubble water booster pump and a water-gas mixing tank are sequentially arranged; and a gas storage device, which is connected to the water-gas mixing tank via a gas transmission pipeline, on which a pressure reducing valve is arranged. In the above technical scheme, bubble water is made by a water-gas mixing tank, and a pressure reducing valve is arranged on the gas transmission pipeline, so that the water and gas in the bubble water can be fully mixed, and the water-gas mixing tank will not be damaged or the bubble water will not be sprayed out due to excessive pressure when it is taken, which is safe and reliable. The gas usage speed can also be maintained within an appropriate range, and a sufficient amount of bubble water can be produced using one gas cylinder, and the bubble water can be taken out immediately, and users do not need to wait for freshly made bubble water, thereby improving user experience.

[0034] Exemplarily, the beverage machine further includes a prompt module, a pressure detector is provided on the gas pipeline and downstream of the pressure reducing valve, and the control device is used to control the prompt module to issue a prompt about insufficient gas in the gas storage device when the gas pressure in the gas pipeline is lower than a first preset threshold value according to the detection result of the pressure detector. In the above technical solution, the pressure detector and the prompt module can be provided to timely remind the user to replace the gas cylinder.

[0035] Exemplarily, the water-gas mixing tank is also connected to a pressure relief valve, which opens when the pressure in the water-gas mixing tank is greater than a second preset threshold. In the above technical solution, the pressure relief valve can maintain the pressure within a suitable range to avoid damaging the water-gas mixing tank.

[0036] Exemplarily, a one-way valve is provided on the bubble water pipeline and on the booster pump and the water-gas mixing tank. In the above technical solution, the bubble water one-way valve can prevent the bubble water from flowing back to the cold tank.

[0037] Exemplarily, a bubble water solenoid valve is provided on the bubble water pipeline and between the water-gas mixing tank and the water outlet, and the control device is also used to control the opening and closing of the bubble water solenoid valve according to the user's water intake information. In the above technical solution, the bubble water solenoid valve can control whether to output bubble water and the amount of bubble water output.

[0038] For example, the clean water tank is detachable, wherein the top of the clean water tank is open. In this way, the user can conveniently use the water in the clean water tank for various purposes, and the clean water can be poured out from the top without limiting the flow rate, which provides a better user experience. The open top can also facilitate the user to regularly clean the clean water tank.

[0039] Exemplarily, a cover that can be opened and closed is provided on the top of the clean water tank, so that the external environment can be isolated when the cover does not need to be opened.

DETAILED DESCRIPTION

[0053] In the following description, a large amount of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only exemplarily illustrates a preferred embodiment of the present invention, and the present invention can be implemented without one or more such details. In addition, in order to avoid confusion with the present invention, some technical features well known in the art are not described in detail.

[0054] In order to fully understand the embodiments of the present invention, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other embodiments.

[0055] An embodiment of the present invention provides a beverage machine. The beverage machine has a water inlet and a water outlet, and the beverage machine may include a small-flux water purification device and a control device. Figure 1 As shown, the small flux water purification device 100 has a clean water outlet 102 and a raw water inlet 101 connected to the water inlet end 11. Exemplarily, the central filter element of the small flux water purification device may include a reverse osmosis filter element. The pore size of the reverse osmosis filter element is one-millionth of five (0.0001 microns) of a hair, which is generally invisible to the naked eye, and bacteria and viruses are 5000 times its size. Therefore, only water molecules and some mineral ions that are beneficial to the human body can pass through, and other impurities and heavy metals are discharged from the wastewater pipe to provide users with high-quality clean water. According to the difference in the daily water production of the central filter element, the central filter element with a daily water production of greater than or equal to 400 gallons is a large flux central filter element, and the rest are considered to be small flux central filter elements. For the central filter element including the reverse osmosis filter element, the water needs to be pressurized before entering the central filter element, so a booster pump may also be included in the small flux water purification device 100. The daily water output of the water purification device is limited by the central filter element. As long as the daily water output of the water purification device is less than 400 gallons, it is a small-flux water purification device. Optionally, the small-flux water purification device 100 may also include a pre-filter element, which is located before the central filter element and is used to perform preliminary filtration on the water entering the central filter element to extend the service life of the central filter element. The reverse osmosis filter element or the nanofiltration filter element will produce a certain proportion of concentrated water during the filtration process. In this case, the small-flux water purification device 100 also has a concentrated water outlet 103, and the generated concentrated water is discharged from the concentrated water outlet 103. Figure 2 The water circuit diagram shown includes a water purification device 100 according to an exemplary embodiment of the present invention. The water purification device 100 may include a pre-filter element 140, a booster pump 150 and a reverse osmosis filter element 160 arranged in series. Optionally, a water inlet solenoid valve 110 may be provided between the pre-filter element 140 and the booster pump 150. The concentrated water generated by the reverse osmosis filter element 160 during the water production process is discharged to the concentrated water outlet 103 through the concentrated water solenoid valve 120.

[0056] The lifespan of large-flux central filter elements and small-flux central filter elements is similar, and the former is relatively expensive. The use of small-flux water purification devices can significantly reduce manufacturing costs and the cost of replacing filter elements in the later stage, and provide a better user experience. Of course, with the development of technology, the cost of filter elements may decrease, or users may have higher and higher requirements for water production rates. The division of large-flux and small-flux water purification devices may change as a result, and the definition of small-flux mentioned in this article should also be adaptively changed according to the general consensus in this field.

[0057] Return to see Figure 1 A normal temperature water pipeline 200 is connected between the purified water outlet 102 and the water outlet 12. Figure 3 As shown, a water purification solenoid valve 210 and a water purification tank 220 are sequentially arranged on the normal temperature water pipeline 200. Figure 1 The various components provided on the normal temperature water pipeline 200 are simply summarized as box A. The clean water produced by the water purification device 100 can be stored in the clean water tank 220, and can be provided from the clean water tank 220 to the water outlet 12 when the user needs water. The control device is used to control the water purification solenoid valve 210 to open and control the water purification device 100 to work when there is a lack of water in the clean water tank 220, so as to replenish water in the clean water tank 220. The water shortage condition of the clean water tank 220 can be set as needed, for example: 1) when the liquid level in the clean water tank 220 is lower than its upper limit, it can be considered that the clean water tank 220 is short of water; or, 2) when the liquid level in the clean water tank 220 is lower than its upper limit by a predetermined value, for example, reaching 1 / 2, 1 / 3 or 2 / 3 of the upper limit, it is considered that the clean water tank 220 is short of water; or, 3) when the liquid level in the clean water tank 220 is lower than its lower limit, it is considered that the clean water tank 220 is short of water. The above three water shortage conditions each have their own advantages. Under condition 1), water can be added to the water purification tank 220 in time, but the water purification device 100 may be started and stopped repeatedly. Under condition 3), the number of starts and stops of the water purification device 100 can be reduced, but when the user's water demand is greater than the volume of the water purification tank 220, it may be necessary to wait for the water purification device 100 to produce water. Condition 2) is between the two. Those skilled in the art can set the water shortage condition based on a comprehensive consideration of factors such as the daily water intake of users, the volume of the water purification tank 220, and the water production rate of the water purification device 100. The liquid level in the water purification tank 220 can be detected by various suitable liquid level sensors, weighing sensors, etc.

[0058] A hot water pipeline 300 is also connected between the purified water outlet 102 and the water outlet 12. A hot water solenoid valve 310 and a hot water tank 320 are sequentially arranged on the hot water pipeline 300. Figure 3 As shown. Figure 1In the figure, various components provided on the hot water pipeline 300 are simply summarized as box B. The hot tank 320 can store clean water, heat the clean water therein, and provide it to the user through the water outlet 12. In order to prevent the water in the hot tank 320 from boiling and overflowing, the water in the hot tank 320 is usually heated to a preset temperature or a preset temperature range below the boiling point, for example, below 80 degrees. Exemplarily, a hot tank temperature sensor for detecting the temperature in the hot tank 320 and generating hot tank temperature information can be provided on the hot tank 320, and the hot tank temperature sensor is electrically connected to the control device. When the water temperature in the hot tank 320 is lower than the lower limit of the predetermined temperature range, the heating component in the hot tank 320 is controlled to start heating. When the water temperature in the hot tank 320 reaches the upper limit of the predetermined temperature range, the heating component is controlled to stop heating. In this way, the temperature of the water in the hot tank 320 can be controlled to be constant within a certain range, which can not only prevent the water temperature in the hot tank 320 from being too low, but also avoid the frequent start and stop of the heating component to shorten the service life. For example, a positive temperature coefficient thermistor (PTC element) for constant temperature heating can be used to directly replace the separate temperature sensor and heating assembly. The positive temperature coefficient thermistor for constant temperature heating can heat the temperature in the hot tank 320 and maintain it at a constant temperature through the element itself, so as to achieve a stable output of hot water in the hot tank 320. The control device can control the hot water solenoid valve 310 to open and control the water purification device 100 to work when there is a lack of water in the hot tank 320. Similar to the clean water tank 220, the water shortage condition of the hot tank 320 can be set as needed, for example: 1) when the liquid level in the hot tank 320 is lower than its upper limit, it can be considered that the hot tank 320 is short of water; or, 2) when the liquid level in the hot tank 320 is lower than its upper limit by a predetermined value, for example, reaching 1 / 2, 1 / 3 or 2 / 3 of the upper limit, it is considered that the hot tank 320 is short of water; or, 3) when the liquid level in the hot tank 320 is lower than its lower limit, it is considered that the hot tank 320 is short of water.

[0059] A cold water pipeline 400 is also connected between the purified water outlet 102 and the water outlet 12. A cold water solenoid valve 410 and a cold tank 420 are sequentially arranged on the cold water pipeline 400. Figure 1The various components provided on the cold water pipeline 400 are simply summarized as box C. The cold tank 420 is used to store clean water and refrigerate the clean water therein. An insulation layer can be provided on the outside of the cold tank 420 to prevent the cold water from exchanging heat with the outside world and avoid the need for repeated refrigeration to waste energy. Exemplarily, a refrigeration component can be provided on the cold tank 420, and the temperature of the water in the cold tank 420 can be reduced by the refrigeration component, so that the cold water can be directly provided to the user. As will be described later, the cold water in the cold tank 420 can also be used for ice making or further refrigeration, and then provided to the user. A cold water solenoid valve 410 is provided, and when there is a lack of water in the cold tank 420, the control device can control the cold water solenoid valve 410 to open and control the water purification device 100 to work. Similar to the clean water tank 220, the water shortage condition of the cold tank 420 can be set as needed, for example: 1) when the liquid level in the cold tank 420 is lower than its upper liquid level limit, it can be considered that the cold tank 420 is short of water; or, 2) when the liquid level in the cold tank 420 is lower than its upper liquid level limit by a predetermined value, for example, reaching 1 / 2 or 1 / 3 or 2 / 3 of the upper liquid level limit, the cold tank 420 is considered to be short of water; or, 3) when the liquid level in the cold tank 420 is lower than its lower liquid level limit, the cold tank 420 is considered to be short of water.

[0060] In the above technical solution, when the user needs normal temperature water, it can be directly provided from the clean water tank 220 to the water outlet 12; when the user needs hot water at a higher temperature, it can be directly provided from the hot tank 320 to the water outlet 12 to obtain hot water with a larger flow rate; when the user needs cold water at a lower temperature, it can be directly provided from the cold tank 420 to the water outlet 12. Therefore, the user has greater freedom of choice and can meet more needs of the user. In addition, since the beverage machine 10 is provided with a clean water tank 220, a hot tank 320, and a cold tank 420, all of which have water storage functions and corresponding solenoid valves are provided upstream thereof, this solution of outputting hot water at multiple temperatures can be applied to various types of water purification devices 100, especially to water purification devices 100 with small flux. In addition, when outputting cold water, hot water and normal temperature water, they can not interfere with each other, and the maximum amount of water that can be obtained by these three types of water can reach the maximum capacity of the container storing them, and the user experience is better.

[0061] For example, Figure 3As shown, a first water pump 230 may be provided on the normal temperature water pipeline 200 and downstream of the clean water tank 220, and a second water pump 330 may be provided on the hot tank 320 pipeline and downstream of the hot tank 320. The first water pump 230 and the second water pump 330 can provide pressure for normal temperature water and hot water respectively, so that the water outlet 12 of the output water can be free from height restrictions. Of course, one or more of the first water pump 230 and the second water pump 330 may not be provided, but water is provided to the water outlet 12 by gravity. The beverage machine 10 may also include a mixing water pipeline 500. The water inlet of the mixing water pipeline 500 is connected to the normal temperature water pipeline 200 downstream of the first water pump 230, and the water outlet of the mixing water pipeline 500 is connected to the hot water pipeline 300 downstream of the second water pump 330. A mixing water solenoid valve 510 may be provided on the mixing water pipeline 500. When the desired water intake temperature is room temperature or the water temperature in the hot tank 320, the water mixing solenoid valve 510 can be closed so that the water output does not interfere with each other. When the desired water intake temperature is higher than room temperature and lower than the water temperature in the hot tank 320, the water mixing solenoid valve 510 is opened to mix water through the water mixing pipeline 500. Exemplarily, at least one of the first water pump 230 and the second water pump 330 is a flow-adjustable water pump. In an exemplary embodiment, one of the two water pumps is a flow-adjustable water pump, and the temperature of the output hot water can be controlled to be the desired water intake temperature by adjusting the flow-adjustable water pump. In another exemplary embodiment, both water pumps are flow-adjustable water pumps, and the flow of the two water pumps can be controlled to make the temperature of the output hot water the desired water intake temperature. In short, the control device is used to control the switch of the water mixing solenoid valve 510 and the flow of the flow-adjustable water pump according to the desired water intake temperature and the water temperature in the hot tank 320. In the case where the first water pump 230 is a flow-adjustable water pump, when the expected water intake temperature is high, the control device can control the flow-adjustable water pump to reduce the flow rate to ensure that the output hot water temperature meets the expected water intake temperature; when the expected water intake temperature is low, the control device can control the flow-adjustable water pump to increase the flow rate to ensure that the output hot water temperature meets the expected water intake temperature. In the case where the second water pump 330 is a flow-adjustable water pump, when the expected water intake temperature is high, the control device can control the flow-adjustable water pump to increase the flow rate to ensure that the output hot water temperature meets the expected water intake temperature; when the expected water intake temperature is low, the control device can control the flow-adjustable water pump to reduce the flow rate to ensure that the output hot water temperature meets the expected water intake temperature. When both the first water pump 230 and the second water pump 330 are adjustable in flow rate, the above two adjustment methods can be combined. In order to prevent hot water from flowing back into the clean water tank 220, a normal temperature water check valve 240 is also provided on the normal temperature water pipeline 200, downstream of the clean water tank 220 and upstream of the water inlet of the mixed water pipeline 500. As mentioned below, a heater 340 may be further provided on the hot water pipeline 300. The heater 340 may be provided downstream of the second water pump 330 and the water outlet of the mixing water pipeline 500.The heating body 340 can reheat the hot water delivered by the hot tank 320 or the mixed water delivered by the hot tank 320 and the clean water tank 220 to reach a higher water temperature. In order to allow all the mixed water to pass through the heating body 340, a water outlet solenoid valve 250 is further provided on the normal temperature water pipeline 200 and downstream of the water inlet of the mixed water pipeline 500. The control device can control the water outlet solenoid valve 250 to be closed when the user takes hot water.

[0062] In the above technical solution, the control device is used to control the switch of the mixing water solenoid valve 510 and the flow rate of the flow-adjustable water pump according to the expected water intake temperature and the water temperature in the hot tank 320, so as to ensure that the output hot water temperature meets the expected water intake temperature and can meet the user's requirements for various water temperatures between normal temperature and the water temperature in the hot tank 320.

[0063] For example, Figure 3 As shown, in the case where the beverage machine 10 includes a heating body 340, the control device is also used to control the heating power of the heating body 340 according to the desired water intake temperature, the water temperature in the hot tank 320, and the flow rates of the first water pump 230 and the second water pump 330. In an exemplary embodiment, when the user expects a higher water intake temperature, the temperature of the hot water directly output from the hot tank 320 is not enough to meet the user's needs. At this time, the hot water output from the hot tank 320 can be further heated by the heating body 340 to meet the user's needs. In another exemplary embodiment, the hot water in the hot tank 320 is mixed with the room temperature water in the clean water tank 220, and then heated by the heating body 340 and output to the user, so that a wide range of hot water temperatures can be provided to the user to meet different needs. When there is no hot water in the hot tank 320, the heating body 340 can also be used alone to heat the room temperature water and output hot water at the water intake temperature expected by the user. Since the change of water temperature can be controlled by controlling the heating power of the heating body 340, the heating body 340 has a high response speed, and therefore, the heating body 340 can accurately control the output water temperature to make the output water temperature as close as possible to the user's water intake temperature. The heating power of the heating body 340 can be calculated by the expected water intake temperature, the water temperature in the hot tank 320, and the flow rate of the first water pump 230 and the second water pump 330, so that the flow rate of the flow-adjustable water pumps in the first water pump 230 and the second water pump 330, the heating power of the heating body 340 and other variables can be reasonably allocated, thereby meeting the user's water intake flow rate requirements and ensuring the user's water temperature requirements.

[0064] In the above technical solution, by controlling the heating power of the heating body 340, hot water of the water intake temperature desired by the user can be output, and the water temperature fluctuation is small, the temperature is accurate, the control logic is simple, and the cost performance is high.

[0065] Exemplarily, the beverage machine 10 may further include a first liquid level sensor 221 for detecting the clean water level in the clean water tank 220. The control device is used to determine whether there is a lack of water in the clean water tank 220 according to the clean water level. Exemplarily and not restrictively, the water level detector 320 may include a magnetic float and a magnetic induction switch. The magnetic float may be arranged in the clean water tank 220, and may rise and fall synchronously with the liquid level in the clean water tank 220. The magnetic induction switch may be arranged outside the clean water tank 220, at a height at the water shortage level of the clean water tank 220. When the liquid level drops to the water shortage level, the magnetic induction switch is actuated, and the control device obtains a signal that the liquid level reaches the water shortage level, thereby controlling the water making device 100 to start making water. The first liquid level sensor 221 may also be a liquid level detector such as an infrared liquid level meter or an ultrasonic liquid level meter, which may be completely arranged outside the clean water tank 220 to perform non-contact measurement of the liquid level in the clean water tank 220.

[0066] Exemplarily, the beverage machine 10 may further include a second liquid level sensor 321 for detecting the hot water level of the hot tank 320, and the control device is used to determine whether there is a lack of water in the hot tank 320 according to the hot water level. The second liquid level sensor 321 may be the same as or different from the above-mentioned liquid level sensor. The second liquid level sensor 321 needs to withstand the higher temperature of the hot tank 320, so a liquid level sensor that can withstand high temperatures is selected.

[0067] Exemplarily, the beverage machine 10 may further include a third liquid level sensor 421 for detecting the cold water level in the cold tank 420, and the control device is used to determine whether the cold tank 420 is short of water according to the cold water level. The third liquid level sensor 421 may be the same as or different from the above-mentioned liquid level sensor. The third liquid level sensor 421 needs to withstand the lower temperature of the cold tank 420, so a liquid level sensor that can withstand low temperatures is selected.

[0068] In the above technical scheme, the first liquid level sensor 221, the second liquid level sensor 321 and the third liquid level sensor 421 can respectively measure the water volume information of the clean water tank 220, the hot tank 320 and the cold tank 420, and the second liquid level sensor 321 can withstand higher temperatures, and the third liquid level sensor 421 can withstand lower temperatures, and transmit the water volume information obtained by each to the control device, so that when the clean water tank 220, the hot tank 320 and the cold tank 420 are short of water, they can be replenished in time and overflow caused by excessive water replenishment can be prevented.

[0069] For example, see Figure 7, the beverage machine 10 may further include an ice making module 600, an ice delivery module 610 and an ice storage box 620. The ice making module 600 is in communication with the cold tank 420, and is used to receive water from the cold tank 420 and make ice cubes. The ice delivery module 610 is used to deliver the ice cubes to the ice storage box 620. In an exemplary embodiment, the water in the cold tank 420 is cooled by a refrigeration assembly. When ice making is required, the cold water in the cold tank 420 can be delivered to the ice making module 600. The ice making module 600 further cools the cold water to produce ice cubes. The ice delivery module 610 is used to deliver the produced ice cubes to the ice storage box 620. The ice delivery module 610 may include one or more of a manipulator and a conveyor belt. The ice cubes produced by the ice making module 600 are delivered to the ice storage box 620 by the ice delivery module 610 for temporary storage.

[0070] The ice storage box 620 may have a heat preservation function. It is understood that the ice making device is usually used in a room temperature environment, and the ice storage box 620 does not have a refrigeration function. At room temperature, ice cubes will melt quickly. Therefore, materials such as heat preservation cotton are usually provided to keep the ice storage box 620 warm. The heat preservation material may be provided on the ice storage box 620, or may be provided outside the ice storage box 620 and separated from the ice storage box 620. This can delay the melting of ice cubes.

[0071] The control device can control the ice delivery module 610 to deliver ice cubes to the ice storage box 620 when the ice making module 600 completes ice making. In one embodiment, the ice making module 600 may include an ice cube mold and a refrigeration component, and the refrigeration component refrigerates the ice cube mold to obtain ice cubes that are consistent with the shape of the ice cube mold. The start and stop of the ice making module 600 can be controlled by the control device. For example, when the control device obtains information that the user needs to take ice, the refrigeration component can be controlled to start, thereby causing the ice making module 600 to start making ice. When the refrigeration time reaches a preset time, the refrigeration component is controlled to stop working, so that the ice making module 600 stops making ice. Optionally, the temperature around the ice cube mold can be monitored, and when the temperature reaches a preset value, the ice making module 600 is controlled to stop making ice. At this time, the ice cubes are made, and the ice storage time starts to be counted. At the same time, the ice cubes are delivered to the ice storage box 620 through the ice delivery module 610.

[0072] In the above technical solution, such a beverage machine 10 can also provide ice cubes for the user, and use the cold water in the cold tank 420 to make ice, which can shorten the waiting time of the user.

[0073] For example, Figure 6As shown, the beverage machine 10 may further include an ice quantity detector 640 and a prompt module. The ice quantity detector 640 is used to detect the current ice quantity information in the ice storage box 620. In the illustrated embodiment, the ice quantity detector 640 is disposed on the ice storage box 620, but in other embodiments not shown, the ice quantity detector 640 may also be disposed on other structures other than the ice storage box 620. The ice quantity detector 640 may include any suitable sensor such as an infrared detector, an ultrasonic detector, etc. The current ice quantity information may include one or all of information such as whether there are ice cubes in the ice storage box 620 and the specific amount of ice in the ice storage box 620. Exemplarily, the ice quantity detector 640 may detect the current ice quantity information in the ice storage box 620 and transmit it to the control device.

[0074] The control device is used to control the ice delivery module 610 to deliver ice cubes to the ice storage box 620 and time the ice storage time when the ice making module 600 completes ice making. The ice quantity detector 640 can detect the current ice quantity information in the ice storage box 620 in real time and send it to the control device. Optionally, the ice quantity detector 640 can also start to detect the current ice quantity information in the ice storage box 620 and send it to the control device after the ice delivery module 610 delivers the ice cubes to the ice storage box 620 for a predetermined time. The predetermined time can be greater than or equal to the time it takes for the ice cubes to reach the ice storage box 620 from the ice making module 600. The control device controls the prompt module to issue a prompt message about the ice cubes being not fresh when the ice storage time reaches a preset threshold and it is determined according to the current ice quantity information that there are still ice cubes in the ice storage box 620. Under normal use conditions, the time from making ice cubes to becoming not fresh can be from several hours to more than ten hours, or more.

[0075] The preset threshold value of the ice storage time is usually not greater than the melting time of the ice. It is understandable that when the ice has completely melted or most of it has melted and can no longer be used, it is not very meaningful to remind the user that the ice is not fresh. Moreover, when the size of the ice does not change much, the ice may not be fresh enough and is not suitable for consumption due to the growth of bacteria. Therefore, the preset threshold value can be the time when the designer considers the user's usage scenario and other conditions when designing the product, and the ice is not suitable for use. It can also be the time when the user judges that the ice is not suitable for use according to his own needs. The preset threshold value may also need to be appropriately modified according to the season and environment. For example, in winter and summer, or indoors and outdoors, the change of the external temperature will affect the temperature in the ice storage box 620 to a certain extent, and then affect the bacterial reproduction rate of the ice, resulting in different times when the ice has a peculiar smell, and the preset threshold value needs to be adjusted. The prompt module can use one or more prompt methods such as sound prompts, light prompts, and electronic prompts. Users can also choose appropriate prompt methods according to their own needs, or block unnecessary prompt methods.

[0076] Excessive breeding of ice bacteria and the production of peculiar smells will affect the user's experience and even cause poisoning. By setting a preset threshold for the storage time of ice cubes, users can be reminded in time when the ice cubes are not fresh, which can ensure the freshness of the ice cubes provided to users to a certain extent and improve the user experience. Moreover, in the beverage machine 10 provided in the present application, the ice cubes are immediately transported to the ice storage box 620 after being made, so that users can take them at any time, thereby ensuring the freshness of the ice cubes. Furthermore, the ice cubes will not be repeatedly frozen whether in the ice storage box 620 or in the ice making module 600, which not only ensures the freshness of the ice cubes, but also avoids the freezing of a large amount of ice cubes. After freezing in large quantities, it is not only difficult to remove them from the ice making module 600, but there may also be a serious consequence that a large amount of ice in the device causes damage to the ice making module 600.

[0077] Exemplarily, the beverage machine 10 may further include an input module, which may include one or more of a touch screen and a keypad. Optionally, the input module may also include a receiver for receiving a target ice amount input by a user through a user operation interface on the electronic device. In short, the input module may be used to receive a target ice amount input by a user, generate and send target ice amount information to the control device. The control device may control the beverage machine 10 to make a required number of ice cubes according to the target ice amount information. Since the single ice making amount of the ice making module 600 is limited, the number of ice cubes required by the user may be greater than the single ice making amount. At this time, the control device will control the ice making module 600 to make ice multiple times. Generally, from a cost perspective, the single ice making amount of the ice making module 600 is fixed, so the target ice amount is n times the single ice making amount of the ice making module 600, where n is a positive integer, i.e., an integer multiple of the single ice making amount of the ice making module 600. The aforementioned “the control device controls the ice delivery module 610 to deliver ice cubes to the ice storage box 620 and counts the ice cube storage time when the ice making module 600 completes ice making” includes the following operations:

[0078] Each time the ice making module 600 completes ice making, the control device controls the ice delivery module 610 to deliver the ice cubes of a single ice making amount to the ice storage box 620; and when it is determined that the ice storage box 620 is emptied according to the current ice amount information, the ice storage time is re-timed from the next time the ice making module 600 completes ice making. Starting the timing from when the ice cubes are made by the ice making module 600 can better judge the freshness of the ice cubes. It can be understood that the preparation of ice cubes requires a certain amount of time, and the user may take away all or part of the ice cubes in the ice storage box 620 before all the ice cubes of the required amount of ice cubes are prepared. Specifically, when the target ice amount required by the user is 2 times or more of the single ice making amount of the ice making module 600, it is possible that after the first ice making is completed, the user does not take away all the ice cubes prepared for the first time, so whether the ice cubes in the ice storage box 620 are fresh should be counted from the time when the ice making module 600 produces the first batch of ice cubes after the user starts making ice, because if the first batch of ice cubes are not fresh, they may contaminate the subsequent ice cubes. If the user takes away all the ice cubes, that is, when it is determined that the ice storage box 620 is emptied based on the current ice quantity information, the ice storage time is re-timed from the next time the ice making module 600 completes ice making.

[0079] This arrangement allows the user to obtain the required number of ice cubes with one input, thus simplifying the operation. When the ice cubes are made, they can be promptly delivered to the ice storage box 620 through the ice delivery module 610, thus reducing the waiting time of the user. Furthermore, when the number of ice cubes required by the user is greater than the single ice making amount and the device needs to make ice multiple times, it is avoided that the first batch of ice cubes in this ice making task is not fresh and contaminates the subsequent ice cubes, thereby always providing the user with the freshest ice cubes.

[0080] The single ice-making time of the ice-making module usually does not exceed 10 minutes. Therefore, for the target ice amount set by the user, even if multiple ice-making is completed, the time from the first ice-making completion to the last ice-making completion will not exceed the preset threshold, making the ice cubes stale.

[0081] In the above scheme, when the ice-making module needs to make ice multiple times, the present application does not exclude the embodiment in which the ice cubes are temporarily stored in the ice-making module or temporarily stored on the ice delivery module 610 after each ice making, and after all the ice cubes required by the user are made, they are transported to the ice storage box 620 through the ice delivery module 610.

[0082] For example, the target ice quantity input by the user may be less than the maximum ice storage capacity of the ice storage box 620. If the target ice quantity is greater than the maximum ice storage capacity of the ice storage box 620, ice cubes will overflow from the ice storage box 620, and even jam the ice delivery module 610 or the ice making module 600, resulting in malfunction or even damage to the beverage machine 10. To avoid the above situation, a protection logic is set in the control device, which can ensure that the target ice quantity is appropriate and ice cubes will not overflow from the ice storage box 620, causing waste or damage to the device.

[0083] Exemplarily, the control device may also be used to control the prompt module to issue a prompt message about emptying the ice storage box 620 when receiving the target ice quantity information from the input module, if it is determined that the ice storage box 620 has not been emptied according to the current ice quantity information. Each time the input module receives the target ice quantity information from the user, the control device will determine whether the ice storage box 620 has been emptied according to the current ice quantity information. If the ice storage box 620 has not been emptied, the control device controls the prompt module to issue a prompt message about emptying the ice storage box 620. Before the user empties the ice storage box 620, the control device will not control the ice making module 600 to make ice. As described above, the volume of the ice storage box 620 is limited, and ice making is performed after the user empties the ice storage box 620, also to avoid ice cubes overflowing from the ice storage box 620, causing waste or damage to the device.

[0084] For example, when the control device determines that there is no ice in the ice storage box 620 and the ice making module 600 stops making ice according to the current ice amount information, the control prompt module sends a prompt message about no ice at this time to prompt the user that there is no ice in the ice storage box 620. The user can decide whether to make ice according to actual needs. If the user takes away the ice in the interval between two ice makings, or the ice making function has been started but the ice has not been made, it is obviously not necessary to prompt the user to make ice.

[0085] In order to slow down the melting speed of ice cubes in the ice storage box 620 and further keep the ice cubes warm, a movable cover plate can be set on the top of the ice storage box 620, or a push-pull drawer-type ice storage box 620. Before the movable cover plate is opened or the ice storage box 620 is pulled out from the main body of the beverage machine 10, it is not convenient to know the information of the ice cubes therein. By setting the ice quantity detection function, it is convenient for the user to know whether there are ice cubes at present, so as to make ice in time as needed; on the other hand, if the ice cube information prompted by the machine is inconsistent with the actual situation, the user can be reminded of the equipment failure and handle it in time to avoid the beverage machine 10 working in abnormal conditions for a long time.

[0086] Exemplarily, the beverage machine 10 may further include an installation position detector for detecting whether the ice storage box 620 is installed in place and sending the detection result to the control device. The detection result may indicate that the ice storage box 620 is installed in place or the ice storage box 620 is not installed in place. The installation position sensor may include one or more of an infrared transmitter and receiver, various types of contact switches and proximity switches, and any other suitable sensors, etc., to detect whether the ice storage box 620 is installed in place. The control device controls the ice delivery module 610 to deliver ice cubes to the ice storage box 620 when the ice storage box 620 is installed in place. Only when the ice storage box 620 is installed in place, the control device will control the ice delivery module 610 to deliver ice cubes to the ice storage box 620, otherwise the control ice delivery module 610 does not work. In this way, it can be avoided that the ice delivery module 610 delivers ice cubes to the ice storage box 620 when the ice storage box 620 is not placed or the ice storage box 620 is skewed, thereby avoiding the occurrence of ice cubes falling and wasting.

[0087] Since the ice delivery module 610 delivers ice cubes to the ice storage box 620 only when the ice storage box 620 is installed in place, the ice may still remain in the beverage machine 10. Exemplarily, the control device is also used to control the ice making module 600 to stop making ice each time the ice making module 600 completes ice making and determines that the ice storage box 620 is not installed in place. When the ice storage box 620 is not in place, if the ice making module 600 still continues to make ice, a large amount of ice cubes may be formed in the ice making module 600, making it difficult to separate the ice cubes from the ice making module 600, or the ice delivery module 610 cannot be transported due to the large ice cubes, or even damage the ice making module 600. Therefore, when the ice storage box 620 is not in place, when the ice making module 600 completes the current ice making process, it stops making ice, so that the size of the ice cubes can be within a controllable range, which is convenient for the storage and transmission of ice cubes, reduces energy waste, and can also avoid damage to the beverage machine 10, thereby improving the user experience. At this time, the ice cubes may melt. As will be described later, the beverage machine 10 is provided with a good water recovery component, so that no water leakage will occur even if the ice cubes melt.

[0088] As previously mentioned, the ice-making module 600 may include an ice cube mold and a refrigeration assembly. In this embodiment, ice cubes are formed in the ice cube mold. This type of ice cube mold is usually provided with a plurality of ice grooves, and the position of each water injection into the ice groove may be fixed, so that the structure of the device is relatively simple. In order to allow water to reach all ice grooves, the tops of the ice grooves are connected to each other, and the volume of the ice cubes will increase after freezing, which may cause the final frozen ice cubes to be connected into one piece. The transmission of a whole piece of ice requires that the ice transport module 610 and the ice storage box 620 are both of sufficiently large size, and it is not convenient for users to use. In addition, before the ice cubes are transported, the ice cubes need to be demolded first. This type of ice cube has a large contact area with the ice cube mold, and demolding is very laborious. Based on this, in another set of embodiments, the ice-making module 600 may include one or more ice-making heads 650 (see Figure 4 and 6 ), a refrigeration assembly 660 for refrigerating the ice-making head 650 (see Figure 4 and 5 ), and ice making water storage box 670 (see Figure 4 and 6 ). The ice-making water storage box 670 has an ice-making position (the position shown in the figure). When the ice-making water storage box 670 is in the ice-making position, the ice-making head 650 extends into the ice-making water storage box 670. When making ice, water for making ice will be injected into the ice-making water storage box 670. The ice-making head 650 is arranged above the ice-making water storage box 670. The water submerges the ice-making part of the ice-making head 650. As the temperature of the ice-making head 650 gradually decreases, the ice-making part is gradually covered by ice cubes, thereby generating ice cubes on the ice-making head 650. In this way, by controlling the spacing between the multiple ice-making heads 650 and the refrigeration time of the refrigeration assembly 660, it can be ensured that two adjacent ice cubes will not be connected to each other. Moreover, each ice cube only contacts its own ice-making head 650, so the contact area is small, which facilitates the separation of the ice cube from the ice-making head 650. In addition, when the refrigeration assembly 660 stops refrigeration, the temperature of the ice making head 650 can be quickly increased compared to the temperature of the ice cube mold, so that the ice cubes can be easily separated from the ice making head 650, thereby simplifying the control logic. In addition, this ice making water storage box 670 can be easily replenished with water.

[0089] For example, the control device controls the working time of the refrigeration assembly 660 so that there is water remaining in the ice making water storage box 670 each time ice making is completed. This can prevent all the water from freezing into ice cubes, causing the ice making head 650 and the ice making water storage box 670 to freeze completely, and can also prevent the ice making water storage box 670 from being unable to leave the ice making position and the ice cubes being too large to be transported by the ice delivery module 610.

[0090] For example, Figure 6As shown, the ice delivery module 610 may include an ice delivery track 611, and the ice receiving portion of the ice delivery track 611 is located directly below the ice making head 650. That is, the projection of the ice making head 650 in the horizontal plane falls within the projection of the ice receiving portion in the horizontal plane. In this way, the ice cubes dropped from the ice making head 650 can fall into the ice receiving portion of the ice delivery track 611. The ice receiving portion can be any part of the ice delivery track 611, as long as it can receive the ice cubes dropped from the ice making head 650. In this way, when the temperature of the ice making head 650 rises, the part of the ice cube that contacts the ice making head 650 melts, and the ice cube falls into the ice receiving portion of the ice delivery track 611 after falling. Optionally, the ice output portion of the ice delivery track 611 is located directly above the ice storage box 620. The projection of the ice output part in the plane where the opening of the ice storage box 620 is located falls into the opening of the ice storage box 620, so that the ice cubes output by the ice output part can fall into the ice storage box 620. In this way, the ice cubes can fall on the ice transport track 611 under the action of gravity, and when they are transported to the ice output part by the ice transport track 611, they can directly slide or roll into the ice storage box 620. Optionally, the ice transport track 611 may also include a conveyor belt, etc. Preferably, the ice transport track 611 is inclined downward in the direction from the ice receiving part to the ice output part. In this way, the ice cubes can slide from the ice receiving part of the ice transport track 611 to the ice output part under the action of gravity, and fall into the ice storage box 620. In this way, the structure of the product can be further simplified and the cost can be reduced. Figure 4 As shown, the ice delivery module 610 may further include a driver 612, and the ice making water storage box 670 may be moved between the ice making position and the demoulding position under the action of the driver 612. When the ice making water storage box 670 is in the demoulding position, it is outside the falling path of the ice cubes between the ice making head 650 and the ice cube receiving part. In other words, there is no shielding between the ice making head 650 and the ice cube receiving part of the ice delivery track 611. This design allows the ice cubes to enter the ice cube receiving part by gravity after being made, and the ice making water storage box 670 can be immediately put into the next ice making work after the ice cubes in the ice making head 650 are emptied, thereby improving the ice making efficiency when the user needs a large amount of ice cubes, simplifying the structure of the beverage machine 10, reducing costs, and making it more reliable.

[0091] For example, the ice making water storage box 670 can move between the ice making position and the demolding position by one or more translations under the action of the driver 612, or can rotate along its axis to avoid the falling track of ice cubes and reach the demolding position. The ice making water storage box 670 may not completely avoid the falling track of ice cubes. When reaching the demolding position, the ice cubes can fall into the ice making water storage box 670, and then be guided by the box wall and fall into the ice cube receiving part of the ice delivery track 611 below; or when in the ice making position, the ice cubes can fall into the ice making water storage box 670, and when the ice making water storage box 670 moves from the ice making position to the demolding position, the ice cubes can be dumped into the ice cube receiving part of the ice delivery track 611, etc.

[0092] Exemplarily, the driver 612 is used to drive the ice-making water storage box 670 to rotate around the horizontal axis so that the ice-making water storage box 670 moves between the ice-making position and the demoulding position. When it is located directly below the ice-making head 650, it is the ice-making position, at which time the ice-making water storage box 670 can store the most water. When it rotates to the demoulding position, ice cubes from the ice-making head 650 can fall below. The ice-making water storage box 670 can rotate to the demoulding position, which has a simple structure, low cost, and is more stable and reliable.

[0093] The ice-making heads 650 may be multiple and arranged in one or more rows along the horizontal axis, so that when making ice, multiple ice cubes can be made at one time. The cross section of the ice-making water storage box 670 perpendicular to the horizontal axis may be a semicircle, with the horizontal axis as the axis of the semicircle. The semicircle may include 1 / 2 circle or slightly larger than 1 / 2 circle or slightly smaller than 1 / 2 circle, etc. In this way, when pouring out the ice cubes and residual water at the demoulding position, there will be no residue, and the design is easier. When the cross section of the ice-making water storage box 670 is larger than 1 / 2 circle, its water storage capacity is large, and a larger angle needs to be rotated to ensure that the ice cubes fall below; and when the cross section is 1 / 2 circle or less than 1 / 2 circle, the ice cubes can be guided by the ice-making water storage box 670 when falling, and a smaller angle can be rotated to make the ice cubes fall below. Therefore, it is necessary to determine the demoulding position according to the shape of the cross section of the ice-making water storage box 670 to ensure that the ice cubes will not be unable to be poured out in the ice-making water storage box 670. The cross section of the ice-making water storage box 670 is semicircular, which can facilitate its rotation to the demoulding position. This has a simple structure, low cost, and is more stable and reliable.

[0094] For example, reference Figure 6As shown, at least the ice receiving portion of the ice delivery track 611 is provided with a first drain hole 6111, and the residual liquid water poured out can be discharged through the first drain hole 6111 when the ice making water storage box 670 reaches the demoulding position. The first drain hole 6111 is connected to the water inlet of the cold tank 420 through the return pipe 6112, so that the water with a lower temperature after ice making can be collected for the next ice making, without repeatedly refrigerating the water at room temperature. The cold tank 420 can include two water inlets, one of which is connected to the clean water outlet 102 of the water purifier 100 via a cold water solenoid valve, so that the cold tank 420 is replenished and stopped in time when it is short of water and full of water. The other water inlet of the cold tank 420 can be connected to the water outlet of the return pipe 6112. In an embodiment not shown, the water inlet of the cold tank 420 can also be one place, and the water inlet of the clean water and the first drain hole 6111 are both connected here.

[0095] The first drainage hole 6111 is provided to prevent water from entering the ice storage box 620, and also to prevent ice and water from being transported on the ice delivery track 611, so that ice cubes may freeze on the ice delivery track 611. In addition, as mentioned above, in order to prevent ice cubes and the ice-making water storage box 670 from freezing, after each ice cube is made, there is water left in the ice-making water storage box 670, and the first drainage hole 6111 and the return pipe 6112 can facilitate this part of water to flow back into the cold tank 420, so that this part of water can be recycled and utilized, avoiding waste of resources.

[0096] For example, Figure 7 As shown, a sterilization component 680 may be provided on the return line 6112. A sterilization component may also be provided in the cold tank 420. The sterilization components in the return line 6112 and the cold tank 420 may be provided in one or both places, and no limitation is made here. Since the ice water may be contaminated by bacteria in the air during ice making, when the residual ice water of ice making flows back into the cold tank 420, the bacteria will be brought into the cold tank 420, causing the cold water outputted by it and the ice cubes produced to have peculiar smell. Therefore, it is necessary to ensure that the bacteria in the water entering the cold tank 420 are sufficiently few. An over-flow sterilization component may be provided on the return line 6112, so as to eliminate the bacteria in the water contaminated during the ice making process, and ensure that no peculiar smell is generated in the cold tank 420. Optionally, a sterilization component may be provided in the cold tank 420, and the sterilization component may directly sterilize the water in the cold tank 420 to prevent bacteria from breeding and contaminating the cold water. The sterilization component can be any component suitable for sterilizing cold water, such as an ultraviolet sterilization lamp and an ozone generator, and basically will not cause the temperature of the cold water to rise. Compared with the overflow type sterilization component arranged on the return line 6112, the sterilization component is arranged in the cold tank 420, and the cold water can be continuously sterilized, ensuring the sanitation and reliability of the water used for ice making and ice cubes; and the overflow type sterilization component sterilizes less water per unit time, and can stop working when ice making stops, which is energy-saving and environmentally friendly.

[0097] In the above technical solution, the sterilization component is provided to prevent the growth of bacteria in the cold tank 420 from affecting the freshness of ice cubes and cold water.

[0098] For example, Figure 4-5 As shown, the control device can control the refrigeration assembly 660 to reduce the intensity of refrigeration on the ice-making head 650 when the ice-making module 600 completes ice making, so that the ice cubes are separated from the ice-making head 650. The refrigeration assembly 660 reduces the refrigeration intensity, including the refrigeration assembly 660 stopping working or working at a lower power. The ice-making module 600 may include: a refrigerant circulation pipeline, a compressor 661, a heat sink 662 and a defrosting solenoid valve 667. The refrigerant circulation pipeline may include a first heat absorption section 663a and a heat release section 664. The outlet of the first heat absorption section 663a and the inlet of the heat release section 664 are connected by a first pipeline section 665, and the outlet of the heat release section 664 and the inlet of the first heat absorption section 663a are connected by a second pipeline section 666, thereby allowing the refrigerant to circulate in the pipeline. The first heat absorption section 663a and the ice-making head 650 can exchange heat. The refrigerant in the refrigerant circulation pipeline absorbs heat at the first heat absorbing section 663a and changes into a gas state, is compressed into a high-temperature and high-pressure gas at the compressor 661 on the first pipeline section 665, and is cooled and changed into a liquid state by the heat dissipation device 662 provided at the heat releasing section 664. The ice-making head 650 and the first heat absorbing section 663a can be integrated, and the refrigerant evaporates inside the ice-making head 650, thereby reducing the temperature of the ice-making head 650. Of course, the ice-making head 650 and the first heat absorbing section 663a can also be separate components, and the first heat absorbing section 663a can also run through the refrigeration head or be arranged around the refrigeration head, as long as the temperature between the ice-making head 650 and the first heat absorbing section 663a can be increased or decreased through heat exchange. The defrosting solenoid valve 667 is connected to the refrigerant circulation pipeline in parallel with the heat releasing section 664. The control module can control the defrost solenoid valve 667 to open, so that most of the high-temperature and high-pressure gaseous refrigerant does not pass through the heat release section 664 to cool down, and directly returns to the first heat absorption section 663a through the defrost solenoid valve 667, which can reduce the refrigeration intensity of the ice-making head 650. Under normal circumstances, starting and stopping the compressor 661 will consume more electrical energy. In contrast, reducing the refrigeration intensity through the defrost solenoid valve 667 can save energy, and can enable the ice-making module 600 to quickly achieve ice making and ice cube demoulding, thereby improving user experience.

[0099] Continue as Figure 5As shown, the refrigeration assembly 660 may further include a second heat absorbing section 663b. The second heat absorbing section 663b and the first heat absorbing section 663a may be connected in parallel to the refrigerant circulation pipeline through a three-way switching valve. The second heat absorbing section 663b and the cold tank 420 may be heat exchanged to reduce the temperature of the water inside the cold tank 420. The control module may control the three-way switching valve to allow the refrigerant to pass only through the first heat absorbing section 663a when making ice, and to allow the refrigerant to pass only through the second heat absorbing section 663b when cooling water.

[0100] For example, the beverage machine 10 may also have a drain port 13 for communicating with the outside, and the water purification device 100 includes a concentrated water pipeline 103 connected to the drain port 13, and the concentrated water pipeline 103 and the heat release section 664 of the refrigeration component can exchange heat, such as Figure 4 As shown. The refrigeration component may also include a heat sink 662. When the refrigeration component is working, the heat generated by the heat release section 664 needs to be dissipated outwardly through the heat release device 662. The heat release device 662 can be air-cooled, that is, the heat is taken away by the fan through the air. As described above, the water purification device 100 will generate a certain proportion of concentrated water when making purified water, which needs to be discharged to the outside of the beverage machine 10 through the drainage end 13. Since the specific heat capacity of water is much greater than that of air, when the same mass of water and air receive the same amount of heat, the rising temperature of water is much lower than that of air. Therefore, when the heat release section 664 dissipates heat, the temperature difference with the water is greater than the temperature difference with the air, so that heat can be transferred to the water faster. And transferring heat to the water can avoid the increase of indoor temperature to a certain extent. The concentrated water with a higher temperature after passing through the heat release section 664 can take away the heat and be discharged through the drainage end 13. In the above technical solution, the heat generated by refrigeration can be taken away by the discarded concentrated water, the efficiency of refrigeration and ice making can be improved, energy consumption can be reduced, and the impact on room temperature can be reduced to a certain extent, improving user experience.

[0101] like Figure 6As shown, the bottom of the ice storage box 620 may be provided with a second drain hole 621, and the second drain hole 621 is connected to the drain end 13. When the ice cubes stored in the ice storage box 620 melt, the second drain hole 621 can drain the water and drain it to the outside through the drain end 13 of the beverage machine 10. This can not only ensure the cleanliness of the ice cubes, but also prevent the accumulation of water from causing bacterial growth and further shortening the shelf life of the ice cubes. Exemplarily, the cold tank 420 can be located below the ice delivery module 610. In this way, the residual ice water in the ice making water storage box 670 after each ice making can flow directly into the cold tank 420 through the first drain hole 6111 and the return pipe 6112 under the action of gravity, without the need to provide an additional pumping device. At this time, since the ice-making water storage box 670 is above the cold tank 420, a third water pump 430 can be provided on the water supply pipeline 450 between the cold tank 420 and the ice-making module 600 to pump the cold water in the cold tank 420 into the ice-making water storage box 670. By controlling the working time of the third water pump 430, the pumping of water can be stopped after the ice-making water storage box 670 is filled, so as to avoid the water in the ice-making water storage box 670 being constantly replaced by the relatively high temperature water pumped by the third water pump 430, thereby extending the ice-making time. Optionally, see Figure 4 , the third water pump 430 can be arranged on the cold water pipeline 400, so that the third water pump 430 can also be used to pump cold water to the water outlet 12. At this time, the water inlet of the water supply pipeline 450 is connected to the cold water pipeline 400 downstream of the third water pump 430. A first solenoid valve 451 can be arranged on the water supply pipeline 450, and the water supply to the ice-making water storage box 670 is controlled by opening and closing the first solenoid valve 451. On the cold water pipeline 400, a second solenoid valve 411 can be arranged downstream of the third water pump 430. In this way, when the third water pump 430 is working, the direction of water flow can be controlled by controlling the opening and closing of the first solenoid valve 451 and the second solenoid valve 411. In other embodiments, the cold tank 420 can be arranged above the ice-making water storage box 670, and the ice-making water storage box 670 can be filled by gravity. At this time, the residual ice water can be pumped back to the cold tank 420 by other pumping devices. Of course, the present application does not exclude the embodiment in which the residual ice water is directly discharged into the drainage end 13 after ice making, rather than flowing back into the cold tank 420. In this way, there is no need to set up an additional pumping device, which reduces the cost and makes the beverage machine 10 more compact.

[0102] like Figure 7 As shown, a fourth water pump 440 may also be provided, and the fourth water pump 440 is connected between the water outlet of the cold tank 420 and the water outlet end 12 to directly provide cold water to the user.

[0103] The cold tank 420 is arranged below the ice delivery module 610, so that the residual ice water after ice making can flow back into the cold tank 420 by gravity, saving resources and energy. The cold water in the cold tank 420 is pumped to the refrigeration assembly 660 by the third water pump 430, so the approximate amount of cold water pumped can be controlled, and the cold water temperature is low, so the speed of ice making is faster, reducing the waiting time of users.

[0104] Exemplarily, the beverage machine 10 may further include a bubble water module 700, such as Figure 8 As shown, the bubble water module 700 is connected between the cold tank 420 and the water outlet 12, and the water outlet 12 may also include a bubble water outlet for providing bubble water to the user. Since the solubility of carbon dioxide used in bubble water decreases with increasing temperature, and for the taste of bubble water, the bubble water module 700 is used to obtain purified water from the cold tank 420 and make bubble water. In this way, the bubble water with a lower temperature has a better taste, and can dissolve more carbon dioxide and more bubbles.

[0105] In the above technical solution, a bubble water module 700 is provided and cold water is provided to the bubble water module 700 from the cold tank 420, so that bubble water with a lower temperature, better taste and sufficient bubbles can be provided to the user, thereby enriching the user experience.

[0106] For example, reference Figure 8, the bubble water module 700 may include a bubble water pipeline 710 connected between the cold tank 420 and the water outlet 12. A water-gas mixing tank 712 is provided on the bubble water pipeline 710. In order to dissolve more gas and allow water to be replenished in the water-gas mixing tank 712 when the water pressure is high, a bubble water booster pump 711 is also provided on the bubble water pipeline 710 upstream of the water-gas mixing tank 712. In order to facilitate the user to replenish carbon dioxide for the beverage machine 10, the bubble water module 700 may also include a gas storage device 720, and the gas storage device 720 is connected to the water-gas mixing tank 712 through a gas transmission pipeline. A carbon dioxide gas cylinder 722 may be provided in the gas storage device 720, and this gas cylinder 722 has a low cost and is easy to replace. The gas provided by the gas storage device 720 and the cold water provided by the cold tank 420 can be mixed in the water-gas mixing tank 712, so that the water and gas can have a larger contact area, so that the gas is better dissolved in the water. The prepared bubble water is stored in the water-gas mixing tank 712 and can be directly provided to the user when the user takes it. Since the solubility of gas in water increases with the increase of pressure, the water-gas mixing tank 712 is filled with carbon dioxide gas with a relatively high pressure, and the water-gas mixing tank 712 is a pressure-bearing container. In order to store a larger amount of carbon dioxide in a smaller gas cylinder 722, there is a relatively high pressure in the gas cylinder 722 when it leaves the factory. Therefore, a pressure reducing valve 721 can be provided on the gas transmission pipeline. The pressure reducing valve 721 can control the pressure in the gas transmission pipeline and the water-gas mixing tank 712 connected to the gas transmission pipeline, so that the pressure is maintained within a more appropriate range to avoid damaging the water-gas mixing tank 712. Usually, the pressure of the pressure reducing valve 721 is set at 0.6Mpa, so that the bubble water produced has the best taste. In addition, there is enough pressure inside the water-gas mixing tank 712 to press the bubble water inside to the bubble water outlet without the need for an additional pumping device.

[0107] In the above technical solution, the bubble water is made by the water-gas mixing tank 712, and the pressure reducing valve 721 is arranged on the gas transmission pipeline, so that the water and gas in the bubble water can be fully mixed, and the water-gas mixing tank 712 will not be damaged or the bubble water will be sprayed out due to excessive pressure when it is taken, which is safe and reliable. The gas usage speed can also be maintained within an appropriate range, and a sufficient amount of bubble water can be made by using one gas cylinder 722, and the bubble water can be taken out immediately, and the user does not need to wait for the freshly made bubble water, thereby improving the user experience.

[0108] Exemplarily, the beverage machine 10 may further include a prompt module, and a pressure detector 724 is provided on the gas pipeline and downstream of the pressure reducing valve 721. As the amount of bubble water produced increases, the pressure in the gas cylinder 722 will gradually decrease. When the pressure in the gas cylinder 722 is lower than a certain limit, bubble water cannot be produced any more. The control device is used to determine the air pressure in the gas pipeline according to the detection result of the pressure detector 724. When the air pressure in the gas pipeline is lower than the first preset threshold, it can be considered that the gas in the gas cylinder 722 is exhausted at this time, and the pressure is not enough to continue to produce bubble water. The first preset threshold can be slightly greater than the pressure of the gas cylinder 722 when bubble water cannot be produced at all, or it can be set to be larger to ensure that when the gas cylinder 722 is replaced, the bubble water produced can just meet the taste required by the user. In other words, the first preset threshold can also be set according to the needs of the user, or a default value can be set according to the feedback of most users, and no additional restrictions are made here. At this time, the control device can control the prompt module to issue a prompt about insufficient gas in the gas storage device 720.

[0109] Exemplarily, the water-gas mixing tank 712 may also be connected to a pressure relief valve 723, which opens when the pressure in the water-gas mixing tank 712 is greater than a second preset threshold. Thus, excess gas can be discharged through the pressure relief port. It is understood that when the bubble water module 700 is designed, it will be avoided that the pressure in the water-gas mixing tank 712 is too high due to continuous water injection. However, the bubble water in the water-gas mixing tank 712 is not stable. When the ambient temperature rises or is subjected to vibration and impact, the bubble water will decompose, causing the pressure in the water-gas mixing tank 712 to increase suddenly. In order to prevent the bubble water from flowing back to the cold tank 420, or the gas from being ejected from the gas cylinder 722 when the gas cylinder 722 is replaced, a bubble water check valve 714 is provided between the bubble water booster pump 711 and the water-gas mixing tank 712 on the bubble water pipeline 710, and a gas check valve 714 is also provided between the pressure reducing valve 721 and the water-gas mixing tank 712. This will cause the sudden increase in pressure to have nowhere to be released, thereby causing an impact on the water-gas mixing tank 712, reducing the service life of the water-gas mixing tank 712, and even causing safety hazards. The pressure relief valve 723 is set to release excess gas and pressure. The second threshold is less than the rated pressure of the water-gas mixing tank 712, and a certain margin can be reserved. It is greater than the normal working pressure, and a certain margin can also be reserved to consider the pressure fluctuations in normal use.

[0110] Exemplarily, a throttle valve 725 may be provided on the bubble water pipeline 710 between the water-gas mixing tank 712 and the water outlet 12. The difference between the flow rate of the throttle valve 725 and the flow rate of the bubble water booster pump 711 is within a predetermined range. In other words, the flow rate of the bubble water booster pump 711 replenishing water into the water-gas mixing tank 712 is roughly equal to the flow rate of the bubble water output through the throttle valve 725. Since it is only necessary to ensure that the amount of water in the water-gas mixing tank 712 is not too little, the above-mentioned water replenishment flow rate and output flow rate can be completely equal, or there can be a certain difference. As long as it does not cause the amount of water in the water-gas mixing tank 712 to be too little and thus affect the taste of the bubble water, then this difference can be considered to be within a predetermined range. This can prevent the bubble water flow rate from being too large, resulting in a serious imbalance in the water and gas ratio in the mixing tank, affecting the taste of the bubble water. A bubble water solenoid valve 713 is provided on the bubble water pipeline 710 between the water-gas mixing tank 712 and the water outlet 12, and the control device is also used to control the opening and closing of the bubble water solenoid valve 713 according to the user's water taking information. In this way, when the user takes the bubble water, the required amount of bubble water can be input, and the control device can control the time of opening and closing the bubble water solenoid valve 713 to control the output amount of bubble water. Of course, in an embodiment not shown, a mechanical faucet can also be provided, and the user can open and take the bubble water by himself.

[0111] Exemplarily, a refrigeration component may be provided in the water-gas mixing tank 712, so that the user can be provided with sparkling water with the best taste. Preferably, the water-gas mixing tank 712 may be embedded in the cold tank 420, so that the contact area with the cold tank 420 may be increased, the heat may be fully transferred to the cold tank 420, and the water-gas mixing tank 712 may be cooled by the cold tank 420.

[0112] In the above technical solution, the water-gas mixing tank 712 is embedded in the cold tank 420 , and a refrigeration assembly 660 can be used to cool the cold tank 420 and the water-gas mixing tank 712 at the same time, which is more cost-effective and can also reduce the volume of the beverage machine 10 .

[0113] Exemplarily, the clean water tank 220 is detachable, and the beverage machine 10 further includes a support portion for mounting the clean water tank 220, wherein the top of the clean water tank 220 is open. In this way, the user can conveniently use the water in the clean water tank 220 for various purposes, and the clean water can be poured out from the top without limiting the flow rate, which provides a better user experience. The open top can also facilitate the user to regularly clean the clean water tank 220.

[0114] For example, a cover that can be opened and closed can be provided on the top of the clean water tank 220. To prevent dust and bacteria in the air from contaminating the clean water in the clean water tank 220, a cover that can be opened and closed can be provided to isolate the external environment when the cover does not need to be opened. For example, the cover can be a rotatable cover or a detachable cover, as long as the cover can be opened and closed.
