Description

Technical Field

[0001] The utility model relates to the technical field of water refrigeration and cold preservation, and in particular to a water purifier. Background Art

[0002] With the development of the times, water purifiers have been recognized and purchased by most people. Water purifiers can meet users' higher requirements for water quality. Water purifiers can also be equipped with functions such as heating, cooling and ice making to meet the diversified needs of users.

[0003] The existing water purifiers on the market mainly use compressor refrigeration as the refrigeration solution. Compressor refrigeration has high efficiency and can be used not only for cooling water but also for making ice, which is widely popular.

[0004] When the water purifier uses a compressor for cooling, it will produce a lot of noise and cannot provide a quiet working environment. Especially at night, in order to maintain the temperature of the cold water in the water purifier's cooling tank, the compressor starts and stops repeatedly, which will cause great trouble to users. Utility Model Content

[0005] In order to at least partially solve the problems existing in the prior art, some embodiments of the utility model provide a water purifier, including: a cold tank, the cold tank having a water storage space; a refrigeration device, the refrigeration device is used to cool the water in the water storage space, the refrigeration equipment includes a compressor refrigeration device and an additional refrigeration device, the working noise of the compressor refrigeration device is greater than the working noise of the additional refrigeration device; and a controller, the controller is used to control the refrigeration device to work in a first refrigeration mode during the day and in a second refrigeration mode at night, wherein: in the first refrigeration mode, the compressor refrigeration device and the additional refrigeration device work simultaneously or the compressor refrigeration device works alone; in the second refrigeration mode, the additional refrigeration device works alone.

[0006] The water purifier provided by the present application includes a compressor refrigeration device with a relatively high working noise and an additional refrigeration device with a relatively low working noise, and adopts a first refrigeration mode during the day and a second refrigeration mode at night. In the first refrigeration mode, at least the compressor refrigeration device is working, and the compressor refrigeration device has a relatively low refrigeration temperature and a relatively high efficiency, can quickly realize ice making, and has a relatively low energy consumption, and is suitable for daytime use; while in the second refrigeration mode, only the additional refrigeration device is working. Therefore, the noise generated at night is relatively low, and the user experience is relatively good.

[0007] Exemplarily, the additional refrigeration device is a semiconductor refrigerator. Semiconductor refrigerators are usually small in size and light in weight, easy to install and maintain, and suitable for the narrow space inside the water purifier. Semiconductor refrigerators can adjust their power and cooling capacity by adjusting the current, which is convenient for realizing intelligent control of the temperature of the cold water in the cold tank.

[0008] For example, the compressor refrigeration device includes an evaporator, which is arranged in the water storage space. The evaporator is in direct contact with the water in the water storage space, thereby improving energy utilization. Moreover, the volume of the water purifier can be reduced, making the internal structure of the water purifier more compact.

[0009] Exemplarily, a compressor refrigeration device includes a compressor, which is located on a first side outside the cold tank, and a hot end of a semiconductor refrigerator is located on a second side outside the cold tank. The first side and the second side are arranged relative to each other in a horizontal direction. Such an arrangement can prevent heat accumulation in the heating components of multiple refrigeration devices, thereby affecting the normal operation of the equipment.

[0010] Exemplarily, the water purifier also includes a water tank, which is located on the first side of the cold tank, and the water tank is located above the compressor. When the compressor is working, its surface temperature can reach 70°C. Heat is conducted through the air, and the specific gravity of hot air is small, resulting in a relatively high temperature above the compressor. Water has a large specific heat capacity, and the amount of water in the water tank is relatively large, and the temperature will not rise significantly after absorbing a small amount of heat. The lateral size of the water tank is close to the lateral size of the compressor. Placing the water tank above the compressor can effectively utilize the space of the water purifier. And the water tank is arranged above the compressor, and will not be significantly affected by the heating of the compressor.

[0011] Exemplarily, the semiconductor refrigerator further includes a cold end, which is located in the water storage space, and the hot end of the semiconductor refrigerator is located outside the cold tank, and the water purifier further includes a shell, and the cold tank, the refrigeration device and the controller are all located in the shell. The semiconductor refrigerator also includes a heat dissipation component for dissipating heat from the hot end, and the heat dissipation component is sandwiched between the cold tank and the shell. The heat generated by the hot end can be dissipated outwardly through the heat dissipation component via the shell to prevent heat accumulation inside the water purifier.

[0012] Exemplarily, the heat dissipation assembly includes heat dissipation fins and a fan, wherein the heat dissipation fins are close to the hot end of the semiconductor cooler, and the fan is used to generate airflow flowing through the heat dissipation fins. The heat dissipation efficiency can be improved by combining the heat dissipation fins and the fan.

[0013] Exemplarily, the refrigeration device also includes an ice-making module, and the ice-making module is refrigerated by the compressor refrigeration device. The ice-making module is refrigerated by the compressor refrigeration device, because no additional refrigeration equipment and related components are required, the production cost is reduced; in addition, the cost of repair and maintenance is also reduced. Because there is no need to reserve space for additional refrigeration equipment, the water purifier can be designed to be more compact, making the water purifier easier to install or suitable for environments with limited space. As mentioned above, the refrigeration device operates in the first refrigeration mode during the day, and the user's demand for ice is mostly concentrated in the daytime, so the compressor refrigeration device cools the ice-making module to simplify the control logic.

[0014] For example, the ice-making module is located in the cold container and above the water storage space. The low temperature environment in the cold container can speed up the ice-making efficiency of the ice-making module, and the heat absorbed by the ice-making module during operation can also maintain the low temperature in the cold container. In addition, the excess uncondensed water in the ice-making module during the ice-making process can directly fall into the cold container, making the structure more simple and compact.

[0015] Exemplarily, the ice-making module includes: an ice-making head, which is cooled by a compressor refrigeration device and forms ice cubes on the ice-making head; and an ice delivery channel, which is arranged directly below the ice-making head and is used to receive ice cubes, and the ice delivery channel extends downwardly and tilts, and the lower end of the ice delivery channel is aligned with the ice outlet of the water purifier, and the ice delivery channel is provided with a drain hole for water on the ice delivery channel to pass through, and the drain hole is connected to the water storage space. In the process of ice cubes and some residual cold water sliding down the ice delivery channel to the ice outlet, the cold water can return to the cold tank through the drain hole, thereby avoiding the need to provide additional devices to collect this part of cold water, and this part of cold water has a lower temperature, and directly returning to the cold tank can avoid the loss of cold. At the same time, relatively dry ice cubes can enter the ice outlet, and dry ice cubes are not easy to stick, and are less likely to breed bacteria, can be stored for a longer time, and have a relatively good taste.

[0016] Exemplarily, the ice-making module further comprises an ice-making water storage box, the top of the ice-making water storage box has an opening, and the ice-making water storage box can be pivoted between a working position and an ice-dropping position. The ice-making water storage box is in the working position, the opening faces upward, and the ice-making head is arranged in the ice-making water storage box via the opening, and the ice-making water storage box is located outside the ice-dropping path when the ice-making water storage box is in the ice-dropping position, and the opening is tilted or downward. The ice-making head extends into the ice-making water storage box in the working position during ice making. The ice-making water storage box can be moved to the ice-dropping position after the ice-making head completes ice making. The ice-making water storage box is located outside the ice-dropping path when the ice-dropping position is in the ice-dropping position, and the opening is flipped downward to tilt or downward to pour out the water contained in the ice-making water storage box, so as to ensure that the ice cubes and water in the ice-making water storage box can be completely poured out of the ice-making water storage box.

[0017] A series of simplified concepts are introduced in the utility model content, which will be further described in detail in the detailed implementation section. The utility model content section does not mean to attempt to define the key features and essential technical features of the technical solution claimed for protection, nor does it mean to attempt to determine the scope of protection of the technical solution claimed for protection.

[0029] In the following description, a large number 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 illustrates preferred embodiments of the present invention, and the present invention can be implemented without one or more of such details. In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described in detail.

[0030] The inventors found that the refrigeration module of the existing water purifier mainly uses compressor refrigeration because it needs to produce cold water relatively quickly. However, in actual use, the compressor will continue to make noise when the water purifier takes cold water. Since users constantly take cold water, the water purifier needs to add cold water to the cold tank, and even if no water is taken, the cold water needs to be kept at a low temperature. Therefore, the compressor will start and stop frequently and make noise, which cannot meet the user's low-noise usage scenarios (such as cooling and keeping cold at night).

[0031] Based on this, the inventor proposed a new design scheme for the water purifier. In this scheme, the refrigeration module of the water purifier has a compressor refrigeration device and an additional refrigeration device, and the working noise of the compressor refrigeration device and the additional refrigeration device is different. When the user needs low-noise refrigeration, the water purifier only starts the refrigeration device with lower working noise. In the case of no requirement for noise, the water purifier can start all refrigeration devices at the same time, or only start the refrigeration device with higher noise.

[0032] The following will introduce the water purifier according to the embodiment of the utility model in detail with reference to the accompanying drawings. Figure 1A and Figure 1B As shown, the water purifier 1 may include a housing 60. Most of the components of the water purifier 1 are contained in the housing 60, such as Figure 1C and Figure 1D As shown, it includes a cold tank 10, a refrigeration device, a filter element 50, etc., which will be mentioned later. In the illustrated embodiment, the water purifier 1 is a desktop water purifier, so the water purifier 1 also includes a water tank 70. The water tank 70 is detachably connected to the housing 60. The water tank 70 can be used to store raw water. The user can remove the water tank 70, so that the water tank 70 is only carried to a water source such as tap water for filling, without having to carry the entire water purifier. The water tank 70 can be installed to the water purifier body in the lateral direction, and the size of the water tank 70 in the lateral direction may not be greater than half of the size of the water purifier 1 in the lateral direction. The water purifier 1 may be placed in a relatively small space such as a cabinet, with only a small gap around it. The smaller size of the water tank 70 in the lateral direction allows it to be taken out through a smaller gap.

[0033] The filter element 50 may include a reverse osmosis filter element. The pore size of the reverse osmosis filter element is 0.1 micron, which is 10 times smaller than that of a hair. 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 in the form of concentrated water. In this case, the concentrated water can be directly discharged into the water tank 70 to mix with the raw water, or a partition can be provided in the water tank 70 to separate the raw water from the concentrated water. Of course, a separate water tank can also be provided to store concentrated water.

[0034] In other embodiments not shown, the water purifier 1 may also be an under-sink type, which can directly obtain raw water from the tap and discharge concentrated water into the sewer. In this way, the water tank 70 may not be required.

[0035] like Figure 2 and Figure 3 As shown, the cold container 10 has a water storage space 11 inside. The water inlet of the cold container 10 can be connected to the clean water outlet of the filter element 50, and the water outlet of the cold container 10 can be connected to the water inlet. The clean water from the filter element 50 can be temporarily stored in the cold container 10, and provided to the user from the water inlet after being refrigerated. Or the clean water can be stored in the cold container 10 after being refrigerated, so as to provide a large amount of cold water to the user when needed. In order to avoid the massive reproduction of bacteria in the cold container 10, a sterilization device can also be provided in the cold container 10. In order to control the temperature of the cold water in the cold container 10, a temperature detection device can also be provided in the cold container 10.

[0036] See also Figure 1D and Figure 2, the water purifier 1 may include a refrigeration device and a controller. The refrigeration device of the water purifier 1 includes a compressor refrigeration device 21 and an additional refrigeration device 22. The working noise of the compressor refrigeration device 21 is greater than the working noise of the additional refrigeration device 22. The controller is used to control the refrigeration device to work in a first refrigeration mode during the day and in a second refrigeration mode at night. In the first refrigeration mode, the controller controls the compressor refrigeration device 21 and the additional refrigeration device 22 to work simultaneously or the compressor refrigeration device 21 to work alone. In the second refrigeration mode, the controller controls the additional refrigeration device 22 to work alone. In the first refrigeration mode, the compressor refrigeration device 21 and the additional refrigeration device 22 can be made to work simultaneously to have a higher refrigeration efficiency. If the refrigeration efficiency of the compressor refrigeration device 21 can meet the refrigeration demand during the day, in the first refrigeration mode, the compressor refrigeration device 21 can be made to work alone. Alternatively, optionally, the compressor refrigeration device 21 and the additional refrigeration device 22 can be controlled to work simultaneously and the compressor refrigeration device 21 can be controlled to work alone at different time periods during the day. For example, during the period of time when cold water is frequently taken, such as at noon or in the afternoon during the day, the compressor refrigeration device 21 and the additional refrigeration device 22 can be controlled to work simultaneously; during the period of time when cold water is not frequently taken, such as in the morning, the compressor refrigeration device 21 can be controlled to work alone. Alternatively, in the embodiment of water cooling in the cold tank 10, when a large amount of water is just added to the cold tank 10, the compressor refrigeration device 21 and the additional refrigeration device 22 can be controlled to work simultaneously; when the water temperature in the cold tank 10 drops below the preset threshold range, the compressor refrigeration device 21 can be controlled to work alone, and the compressor refrigeration device 21 only needs to maintain the current water temperature in the cold tank 10. Alternatively, according to the expected cold water temperature set by the user, if the expected cold water temperature is relatively high, the compressor refrigeration device 21 can be controlled to work alone; conversely, if the expected cold water temperature is relatively low, the compressor refrigeration device 21 and the additional refrigeration device 22 can be controlled to work simultaneously. Those skilled in the art can choose whether to work simultaneously or individually in the first refrigeration mode as needed.

[0037] Exemplarily, the time periods corresponding to daytime and nighttime can be set at the factory, for example, daytime is 7:00-21:00, and other time periods are nighttime. Of course, depending on the area where the water purifier 1 is used, daytime can also be other time periods. Exemplarily, the time periods corresponding to daytime and nighttime can also be set according to different seasons. Exemplarily, the user can set the time periods corresponding to daytime and nighttime according to his or her own work and rest habits. Or, exemplarily, the controller can collect the user's water extraction time information, and the time period when water is hardly extracted is nighttime.

[0038] For example, the controller can be constructed using electronic components such as timers, comparators, registers, digital logic circuits, etc., or can be implemented using processor chips such as single-chip microcomputers, microprocessors, programmable logic controllers (PLCs), digital signal processors (DSPs), field programmable gate arrays (FPGAs), programmable logic arrays (PLA), application specific integrated circuits (ASICs), and their peripheral circuits. For example, the controller can also be a manual control valve, and the user can manually control the water purifier 1 to switch between the first cooling mode and the second cooling mode.

[0039] The beverage purifier 1 provided in the present application includes a compressor refrigeration device 21 with a relatively high working noise and an additional refrigeration device 22 with a relatively low working noise, and adopts a first refrigeration mode during the day and a second refrigeration mode at night. In the first refrigeration mode, at least the compressor refrigeration device 21 works, and the compressor refrigeration device 21 has a relatively low refrigeration temperature and a relatively high efficiency, can quickly realize ice making, and has a relatively low energy consumption, and is suitable for daytime use; while in the second refrigeration mode, only the additional refrigeration device 22 works. Therefore, the noise generated at night is relatively low, and the user experience is relatively good.

[0040] The compressor refrigeration device 21 may include a compressor 211 and an evaporator (not shown). The evaporator is connected to the compressor 211 through a refrigerant circulation pipeline, and the evaporator is used to refrigerate the cold tank 10. The compressor refrigeration device 21 can use any suitable refrigerant that is currently available or may appear in the future. The refrigerant is powered by the compressor 211 and can circulate in the refrigerant circulation pipeline. The refrigerant can evaporate and become gaseous at the evaporator, thereby absorbing heat around the evaporator and lowering its temperature. Exemplarily, the evaporator can be arranged in the water storage space 11, directly contacting the water in the water storage space 11, thereby improving energy utilization. Moreover, the volume of the water purifier 1 can also be reduced, so that the structure inside the water purifier 1 is more compact. Exemplarily, the evaporator can also be arranged outside the water storage space 11 to refrigerate the cold tank 10, so that the water temperature in the cold tank 10 is reduced.

[0041] See also Figure 3, the additional refrigeration device 22 can be a semiconductor refrigerator, and the semiconductor refrigerator includes a cold end (not shown) and a hot end 221. The working principle of the semiconductor refrigerator is: when a piece of N-type semiconductor material and a piece of P-type semiconductor material are connected to form an electric couple, after the direct current is connected in this circuit, energy transfer can be generated, and the current flows from the N-type element to the joint of the P-type element to absorb heat and become the cold end; the current flows from the P-type element to the joint of the N-type element to release heat and become the hot end. The semiconductor refrigerator has no moving parts, so it will not generate vibration and noise when working, and is suitable for places with high noise requirements. Semiconductor refrigerators usually have a small size and light weight, which is easy to install and maintain, and are suitable for the narrow space inside the water purifier 1. The semiconductor refrigerator can adjust its power and cooling capacity by adjusting the current size, which is convenient for realizing intelligent control of the temperature of the cold water in the cold tank 10.

[0042] For example, see Figure 1C and Figure 1D The compressor 211 of the compressor refrigeration device 21 can be located on a first side outside the cold container 10, and the hot end 221 of the semiconductor refrigerator can be located on a second side outside the cold container 10. The first side and the second side are arranged relatively to each other along a horizontal direction. Exemplarily, the horizontal direction can be the left-right direction or the front-back direction of the water purifier 1. The compressor 211 of the compressor refrigeration device 21 and the hot end 221 of the semiconductor refrigerator are respectively located on two opposite sides of the outside of the cold container 10. This arrangement can prevent the heat generation components of multiple refrigeration devices from generating heat accumulation, thereby affecting the normal operation of the equipment.

[0043] For example, the compressor 211 generates a lot of heat during operation. For example, a common compressor 211 can reach a surface temperature of 70°C after working for a period of time. If the compressor 211 is in contact with the cold container 10, even if the cold container 10 is made of heat-insulating material, the temperature of the water therein may still be affected and increase. Therefore, the compressor 211 should be separated from the cold container 10 when it is set.

[0044] refer to Figure 1D, the water purifier 1 may further include a water tank 70, which is located on the first side of the cold tank 10. That is, the water tank 70 and the compressor 211 are located on the same side of the cold tank 10. Exemplarily, the water tank 70 may be located above the compressor 211. As described above, when the compressor 211 is working, its surface temperature can reach 70°C. Heat is conducted through air, and the specific gravity of hot air is small, resulting in a relatively high temperature above the compressor 211. Water has a large specific heat capacity, and the amount of water in the water tank 70 is relatively large, and the temperature will not rise significantly after absorbing a small amount of heat. The lateral size of the water tank 70 is close to the lateral size of the compressor 211. The water tank 70 is arranged above the compressor 211, which can effectively utilize the space of the water purifier 1. And the water tank 70 is arranged above the compressor 211, which will not be significantly affected by the heating of the compressor 211. Exemplarily and not restrictively, the water tank 70 above the compressor 211 may include: the orthographic projection of the water tank 70 in the horizontal plane and the orthographic projection of the compressor 211 in the horizontal plane at least partially overlap. It is easy to understand that as long as the rising path of the heat generated by the compressor 211 passes through the water tank 70 , the water tank 70 can be said to be above the compressor 211 .

[0045] See also Figure 3 The cold end (not shown) of the semiconductor refrigerator can be arranged in the water storage space 11, directly contacting the water in the water storage space 11, thereby improving the efficiency of heat exchange, and also reducing the volume of the water purifier 1, making the internal structure of the water purifier 1 more compact. Figure 1A , Figure 1C and Figure 2 , the cold container 10, the refrigeration device and the filter element 50 can all be located in the housing 60. The semiconductor refrigerator also includes a heat dissipation component 222, which is used to dissipate heat from the hot end 221. The heat dissipation component 222 can be arranged between the cold container 10 and the housing 60. In this way, the heat generated by the hot end 221 can be dissipated outwardly through the heat dissipation component 222 via the housing 60, thereby preventing heat accumulation inside the water purifier 1.

[0046] Exemplarily, at least the portion of the shell 60 corresponding to the heat dissipation assembly 222 may have the ability to accelerate heat dissipation. For example, the portion may be made of a metal material with higher thermal conductivity, or a heat sink or heat dissipation holes may be provided on the outside of the portion.

[0047] For example, Figure 4As shown, the heat dissipation assembly 222 may include heat dissipation fins 222a and a fan 222b, and the heat dissipation fins 222a are close to the hot end 221 of the semiconductor refrigerator. The heat dissipation fins 222a are usually made of metal materials with good thermal conductivity, such as aluminum or copper. These materials can quickly absorb and transfer heat. The fan 222b is used to generate an airflow flowing through the heat dissipation fins 222a. The heat on the heat dissipation fins 222a is taken away and dissipated into the surrounding environment. The housing 60 may have a heat dissipation opening to accelerate heat dissipation. The airflow generated by the fan 222b is discharged into the environment through the heat dissipation opening after flowing through the heat dissipation fins 222a. In this way, the heat generated by the hot end 221 of the semiconductor refrigerator can be discharged to the outside of the water purifier 1 to the greatest extent. The heat dissipation efficiency can be improved by the combination of the heat dissipation fins 222a and the fan 222b.

[0048] Combined with reference Figure 2 , Figure 3 , Figure 5A and Figure 5B , the water purifier 1 may further include an ice-making module 40, and the ice-making module 40 may be refrigerated by the compressor refrigeration device 21. The ice-making module 40 is refrigerated by the compressor refrigeration device 21, because no additional refrigeration equipment and related components are required, which reduces the production cost; in addition, the cost of repair and maintenance is also reduced. Because there is no need to reserve space for additional refrigeration equipment, the water purifier 1 can be designed to be more compact, which can make the water purifier 1 easier to install or suitable for environments with limited space. As mentioned above, the refrigeration equipment works in the first refrigeration mode during the day, and the user's demand for ice is mostly concentrated in the daytime, so the compressor refrigeration device 21 refrigerates the ice-making module 40, which can simplify the control logic. In some embodiments not shown, the ice-making module 40 can be refrigerated by an additional refrigeration device 22 or other refrigeration equipment.

[0049] Preferably, the ice-making module 40 can be located in the cold container 10 and above the water storage space 11. The low temperature environment in the cold container 10 can accelerate the ice-making efficiency of the ice-making module 40, and the heat absorbed by the ice-making module 40 during operation can also maintain the low temperature in the cold container 10. In addition, the excess uncondensed water in the ice-making module 40 during the ice-making process can directly fall into the cold container 10, making the structure more simple and compact.

[0050] As shown in the figure, the ice making module 40 may include an ice making head 41. The ice making head 41 may be refrigerated by the compressor refrigeration device 21 and ice cubes may be formed on the ice making head 41. Exemplarily, a refrigerant pipeline may be provided in the ice making head 41, and the ice making head 41 is connected to the compressor 211 through a refrigerant circulation pipeline. The ice making head 41 may be considered as an evaporator. The ice making head 41 may generally include a main pipeline 411 and a plurality of ice hanging ends 412 arranged on the main pipeline 411. The plurality of ice hanging ends 412 extend downward from the main pipeline 411 respectively. The plurality of ice hanging ends 412 are spaced apart from each other. The refrigerant pipeline is mainly located in the main pipeline 411, and the plurality of ice hanging ends 412 can be heat exchanged with the main pipeline 411. Optionally, the refrigerant pipeline may also extend from the main pipeline 411 to the plurality of ice hanging ends 412. When the ice making head 41 is working, ice cubes may be formed on the plurality of ice hanging ends 412 respectively, and the size of the ice cubes on the plurality of ice hanging ends 412 may be controlled by controlling the working time of the compressor. If necessary, the ice cubes on the adjacent ice hanging ends 412 can be prevented from contacting each other, so that a small ice cube is formed on each ice hanging end 412. Of course, if necessary, the ice cubes on multiple ice hanging ends 412 can also be connected into a whole block. In some exemplary embodiments, the refrigerant in the refrigerant circulation pipeline can be switched between the ice making head 41 and the evaporator for cooling the water in the water storage space 11 of the cold tank 10 through a switching valve, so that cold water and ice cubes can be obtained using the same compressor refrigeration device 21. In other exemplary embodiments, the compressor 211 can be a variable frequency compressor, and the power of the compressor 211 can be controlled so that the water purifier 1 can switch between the ice making mode and the cooling water mode. The ice making module 40 can provide ice cubes for users, maximize the performance of the compressor refrigeration device 21, and improve the user experience.

[0051] Exemplarily, the ice making module 40 may further include an ice making water storage box 42 and an ice delivery channel 43. The ice making head 41 is cooled by the compressor refrigeration device 21 and ice cubes are formed on the ice making head 41. The top of the ice making water storage box 42 has an opening. The ice making water storage box 42 is in the working position 42a (see Figure 5A ) and ice fall position 42b (see Figure 5B) can be pivoted between. The ice-making water storage box 42 is in the working position 42a, the opening at the top of the ice-making water storage box 42 faces upward, and the ice-making head 41 is arranged in the ice-making water storage box 42 through the opening. The ice-making water storage box 42 is located outside the ice-falling path when it is in the ice-falling position 42b, and the opening is tilted or downward. The ice-making head 41 extends into the ice-making water storage box 42 in the working position 42a during ice making. The ice-making water storage box 42 can be moved to the ice-falling position 42b after the ice-making head 41 completes ice making. The ice-making water storage box 42 is located outside the ice-falling path when it is in the ice-falling position 42b, and the opening is flipped downward to tilt or downward to pour out the water contained in the ice-making water storage box 42, so as to ensure that the ice and water in the ice-making water storage box 42 can be completely poured out of the ice-making water storage box 42. The ice-making head 41 can increase the temperature of the ice-making head 41 through, for example, a defrosting mode. In this way, the part of the ice cube that contacts the ice-making head 41 melts and is then demolded. The demolded ice cube can be poured into the ice-making water storage box 42 together with the residual cold water. The collision between the ice cube and the cold water may cause more water to be provided to the user from the ice outlet. In the case where the user only wants ice cubes, the residual cold water seriously affects the user experience, and this part of the cold water will also be wasted. Preferably, the ice-making water storage box 42 can be removed first, and then the ice cube can be demolded. In this way, relatively dry ice cubes can be provided to the user, and the user experience is good.

[0052] The ice chute 43 may be arranged directly below the ice-making head 41 and used to receive ice cubes. Exemplarily but not limitingly, the ice chute 43 being directly below the ice-making head 41 may include: the projection of the ice chute 43 on the horizontal plane completely covers the projection of the ice-making head 41 on the horizontal plane. It is easy to understand that as long as all the ice cubes naturally falling from the ice-making head 41 can fall on the ice chute 43, it can be said that the ice chute 43 is directly below the ice-making head 41. The ice chute 43 may extend downwardly and the lower end of the ice chute 43 is aligned with the ice outlet of the beverage purifier 1, so that the ice cubes received by the ice chute 43 slide toward the ice outlet of the beverage purifier 1. Exemplarily but not limitingly, the lower end of the ice chute 43 being aligned with the ice outlet may include: a horizontal line is taken along the width direction of the lower end of the ice chute 43, and the projection of the lower end of the ice chute 43 on this horizontal line completely falls into the horizontal projection of the ice outlet on this horizontal line. Such an ice conveying channel 43 has a simple structure and can transport ice cubes only by relying on the gravity of the ice cubes.

[0053] The ice conveying channel 43 may be provided with a drain hole 431 for the water on the ice conveying channel 43 to pass through. The drain hole 431 is connected to the water storage space 11. In the process of ice cubes and some residual cold water sliding down the ice conveying channel 43 to the ice outlet, the cold water can return to the cold tank 10 through the drain hole 431, thereby avoiding the need to provide an additional device to collect this part of cold water. Moreover, this part of cold water has a lower temperature, and directly returning to the cold tank 10 can avoid the loss of cold. At the same time, relatively dry ice cubes can enter the ice outlet. Dry ice cubes are not easy to stick, and are less likely to breed bacteria. They can be stored for a longer time and have a relatively good taste.

[0054] Optionally, the ice making water storage box 42 may be omitted. For example, during ice making, water may be poured toward the ice making head 41 until ice cubes are formed on the ice making head 41. After the ice cubes are formed, the ice cubes may be separated from the ice making head 41. The ice cubes dropped from the ice making head 41 may directly drop onto the ice conveying channel 43 and be transported from the ice conveying channel 43 to the ice outlet.
