Description

Technical Field

[0001] The utility model relates to the technical field of beverage purifiers, and in particular to an ice-making refrigeration device and a beverage purifier provided with the ice-making refrigeration device. 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.

[0003] In order to meet the diverse needs of users, some water purifiers on the market are also equipped with heating, cooling and even ice-making functions, which can provide users with hot water, cold water and ice cubes to enrich the user experience. For water purifiers that can make ice, they usually use high-efficiency compressors and evaporators to make ice. In addition to making ice, they usually also have the function of cooling water. The produced cold water can be stored in a cold water tank, and the cold water can be provided to users through a water pump.

[0004] Existing water purifiers usually have two sets of evaporators, one of which is set on the ice-making head for making ice, and the other evaporator can cool the water in the cold water tank. In other words, the evaporator for making ice is usually only used for making ice, and the evaporator for cooling water is also only used for cooling water. Such water purifiers not only have the problem of idle evaporators, but also require the installation of switching valves and more complicated pipelines, which have a negative impact on maintainability and reliability, and the volume will also increase accordingly. 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 an ice-making refrigeration device. The ice-making refrigeration device includes: an ice-making head, the ice-making head has an ice-making mode for making ice cubes and a cooling water mode for making cold water; a cold water tank, the cold water tank is arranged below the ice-making head, and the cold water tank is used to collect the cold water made in the cooling water mode; and a water supply waterway, the water supply waterway is used to provide the ice-making head with water required for making ice cubes. In the above technical scheme, the ice-making refrigeration device can use the same ice-making head to provide the ice-making mode and the cooling water mode. In the ice-making mode, the ice-making head can make ice cubes, and if the ice-making process produces residual cold water that has not condensed into ice, it can be collected in the cold water tank. In the cooling water mode, the ice-making head can make cold water and store the produced cold water in the cold water tank. When cold water is needed, it can be directly provided to the user from the cold water tank. Therefore, the same ice-making head can be used to provide both ice cubes and cold water, thereby greatly reducing the cost of the ice-making refrigeration device, simplifying the layout of the pipeline and the control logic, and enhancing reliability. The interior of the equipment using the ice-making refrigeration device is more concise, and there is no need to reserve a large space for the ice-making refrigeration device and external pipelines, and the volume can be more compact.

[0006] For example, a water pump is provided on the water supply waterway, and the water inlet of the water pump is connected to the cold water tank, and the water pump is used to pump the water in the cold water tank to the ice making head. Since the cold water tank contains water at a relatively low temperature, the water pump is used to extract cold water from the cold water tank for ice making, which can shorten the time required for ice making and reduce energy consumption.

[0007] Exemplarily, the ice-making refrigeration device further includes: a temperature sensor, the temperature sensor is used to detect the water temperature in the cold water tank; and a controller, the controller is used to control the pumping rate of the water pump according to the water temperature. By detecting the water temperature in the cold water tank and controlling the pumping rate of the water pump, the water temperature in the cold water tank can be kept from being too high, so as to meet the user's demand for cold water.

[0008] Exemplarily, the ice-making refrigeration device further includes: a controller, the controller is used to control the refrigeration power of the ice-making head, and the ice-making head has an ice-making mode and a cooling water mode under the action of the controller. Using a lower cooling power can prevent water from freezing on the ice-making head, and the ice-making head does not need to work intermittently to prevent the volume of ice cubes from being too large. This simplifies the control logic and avoids ice cubes from obstructing the cooling water. Reducing the power of the ice-making head can also reduce the noise of the compressor when it is working.

[0009] Exemplarily, the ice-making refrigeration device further includes a temperature sensor, which is used to detect the water temperature in the cold water tank; the controller is also used to control the refrigeration power of the ice-making head according to the water temperature in the cooling water mode. By appropriately changing the refrigeration power of the ice-making head according to the water temperature, the time required for cooling water can be shortened. Refrigeration is performed with a larger refrigeration power so that the water temperature quickly reaches the lower limit of the cold water temperature threshold. Refrigeration is performed with a smaller power, which reduces the noise of the ice-making refrigeration device and is more energy-efficient.

[0010] Exemplarily, the ice-making refrigeration device further includes an ice-making water storage box, which is used to hold water provided by the water supply waterway. The top of the ice-making water storage box has an opening, and the ice-making water storage box has a working position. When the ice-making water storage box is in the working position, the ice-making head extends into the ice-making water storage box through the opening. The length and width of the ice cubes thus made are more appropriate, and the noise of running water will not be generated all the time, and the user experience is better. In the process of cooling water, water can also be injected into the ice-making water storage box, and cooled by the ice-making head, and the noise of continuous running water will not be generated.

[0011] Exemplarily, the ice-making water storage box also has an ice-dropping position. When the ice-making water storage box is in the ice-dropping position, it is outside the ice-dropping path. The ice-making refrigeration device also includes: a driver. The ice-making water storage box can move between the working position and the ice-dropping position under the action of the driver. In the above technical solution, by moving the ice-making water storage box to the ice-dropping position, the ice cubes can fall directly from the ice-making head, and the ice cubes are relatively dry. The ice-making water storage box can also put the residual cold water into the next ice-making, or pour the residual cold water into the cold water tank before and after the ice cubes are demolded, so as to reduce the waste of residual cold water.

[0012] For example, the ice-making water storage box is rotatably arranged around a horizontal axis between a working position and an ice-dropping position under the action of a driver. When the ice-making water storage box is in the ice-dropping position, the opening is tilted or downward to pour out the water in the ice-making water storage box. Through a motor and a relatively simple structure, it is possible to simultaneously pour cold water into the cold water tank and make ice cubes fall without being hindered by the ice-making water storage box. The control logic is also simpler and the reliability is higher.

[0013] Exemplarily, the ice-making refrigeration device further includes a water pump, the water inlet of the water pump is connected to the water outlet of the cold water tank, and the water outlet of the water pump is connected to the water inlet of the ice-making water storage box. When the water temperature in the cold water tank is high, the water pump can pump water to the ice-making water storage box for cooling, and then enter the cold water tank from the ice-making water storage box, and the cycle continues until the water temperature in the cold water tank reaches a threshold.

[0014] Exemplarily, the water outlet of the water pump is connected to a water supply pipe, which is inserted from the water inlet of the ice-making water storage box to the bottom of the ice-making water storage box. On the one hand, noise can be reduced during the water supply process and almost no bubbles will appear in the water, so that the ice cubes and cold water produced are of better quality. On the other hand, in the ice-making mode, the water entering from the bottom of the ice-making water storage box will not be blocked by ice cubes, nor will it collide with the water surface to cause splashing. In the refrigeration water mode, if a solution of continuously injecting water into the ice-making water storage box is adopted, water with a higher temperature can enter from the bottom of the ice-making water storage box. In this way, the cold water that sinks to the bottom of the ice-making water storage box due to its large specific gravity can be pushed out, so that the cold water with a lower temperature overflows the ice-making water storage box and flows into the cold water tank below.

[0015] Exemplarily, the ice-making refrigeration device further includes: an ice storage box; and an ice delivery channel, which is arranged directly below the ice-making head and is used to receive ice cubes, the ice delivery channel extends downwardly and tilted, the lower end of the ice delivery channel is aligned with the ice inlet of the ice storage box, 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 cold water tank. In the process of ice cubes and some residual cold water sliding down the ice delivery channel to the ice storage box, the cold water can return to the cold water tank through the drain hole, reducing the waste of cold water. At the same time, relatively dry ice cubes can enter the ice storage box, 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, a water outlet is provided at the upper end of the ice conveying channel, and the water outlet is connected to the cold water tank; the ice-making refrigeration device also includes an ice-making water storage box located above the ice conveying channel, the ice-making water storage box has a working position, and the top of the ice-making water storage box has an opening, and when the ice-making water storage box is in the working position, the ice-making head extends into the ice-making water storage box, and the edge of the opening of the ice-making water storage box is provided with an overflow nozzle, which is connected to the water outlet and forms a reflux path to the cold water tank via the overflow nozzle and the water outlet. Excess water can overflow through the overflow nozzle, so there is no need to accurately control the amount of water entering the ice-making water storage box, thereby simplifying the control logic and reducing the control difficulty.

[0017] Exemplarily, the ice-making water storage box also has an ice-dropping position, and the ice-making water storage box can be pivoted around a horizontal axis between a working position and an ice-dropping position, wherein: when the ice-making water storage box is in the ice-dropping position, the opening is tilted or downward to pour out the water contained in the ice-making water storage box. Along the horizontal axis, the ice-making water storage box has a first end and a second end opposite to each other, and the overflow nozzle is located at the first end and the first end is located above the water outlet. In this way, it can be ensured that almost all the overflowing water flows into the water outlet, and a large amount of water is prevented from flowing to the ice storage box through the ice conveying channel, causing the drain hole to not have time to drain the water into the cold water tank, resulting in water accumulation in the ice storage box. At the same time, the ice conveying channel will not be overly wetted by the overflowing water, and the ice cubes will still be relatively dry after passing through the ice conveying channel into the ice storage box, and there will be no risk of ice cubes contacting the wet ice conveying channel and sticking.

[0018] Exemplarily, a guide rib is provided on the inner wall of the ice-making water storage box, the guide rib extends from the first end to the second end, and the guide rib has a third end corresponding to the first end and a fourth end corresponding to the second end, wherein: when the ice-making water storage box is in the working position, the guide rib is inclined upward from the fourth end to the third end; when the ice-making water storage box is in the ice-dropping position, the third end of the guide rib is located above the water outlet. Under the action of the guide rib, the water flow can converge toward the third end to the opening edge of the ice-making water storage box, and then pour down from the edge. The poured water can quickly flow into the cold water tank through the water outlet, and will not flow to the ice storage box along the ice delivery channel, causing the ice delivery channel to be wetted by water. This can ensure that the ice cubes can remain dry after falling and fall smoothly into the ice storage box, and will not be wetted and stick to each other.

[0019] Exemplarily, a receiving groove is provided at the upper end of the ice conveying channel, and the receiving groove extends in a horizontal direction perpendicular to the horizontal axis, and the water outlet is located at the bottom of the receiving groove. When the ice making water storage box is in any position between the working position and the ice dropping position, the overflow nozzle is located above the receiving groove. Part of the cold water can be temporarily stored in the receiving groove, and then all flows into the cold water tank through the water outlet. The vertical groove wall of the receiving groove can prevent the pouring water from splashing out to the part of the ice conveying channel extending to the ice storage box, and then flowing into the ice storage box along the ice conveying channel through the drain hole.

[0020] According to another aspect of the present application, a water purifier is provided, the water purifier includes an output port and the above-mentioned ice-making refrigeration device, wherein: the output port is connected to the ice-making head, and the ice cubes made by the ice-making head are output to the outside of the water purifier through the output port; and the output port is connected to the cold water tank, and the cold water in the cold water tank is output to the outside of the water purifier through the output port. Thus, the shell of the water purifier can provide support and protection for structures such as the ice-making refrigeration device, and at the same time, a window for outputting products such as ice cubes and cold water is provided, and the overall appearance is beautiful and practical, and the structure is firm and reliable.

[0021] Exemplarily, the water purifier also includes: a raw water supply device; a concentrated water discharge device; a filtering device, the filtering device having a raw water inlet, a clean water outlet and a concentrated water outlet, the raw water inlet is connected to the raw water supply device, the clean water outlet is connected to the cold water tank, and the concentrated water outlet is connected to the concentrated water discharge device.

[0022] The filter element can filter the raw water to remove harmful bacteria, heavy metals and other impurities, providing users with high-quality purified water. The water used by the ice-making refrigeration device for ice making is almost free of bacteria and other impurities, so the cold water and ice cubes are of higher quality and can be stored for a longer time. The concentrated water discharge device can also include a drain pipe, and users can connect the drain pipe to the sewer to directly discard the concentrated water containing more impurities.

[0023] Exemplarily, at least one of the raw water supply device and the concentrated water discharge device is a container. The user can remove the water tank and only carry the water tank to a water source such as tap water for filling without carrying the entire water purifier. Concentrated water can be discharged into the water tank, and the user does not need to set up a concentrated water pipe, and can also store the concentrated water for daily use, thereby reducing the waste of water resources.

DETAILED DESCRIPTION

[0040] 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.

[0041] In order to thoroughly understand the implementation of the utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the utility model is not limited to the specific details familiar to those skilled in the art. The preferred implementation of the utility model is described in detail below, but in addition to these detailed descriptions, the utility model can also have other implementations.

[0042] The embodiment of the utility model provides an ice-making refrigeration device. The ice-making refrigeration device according to the embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings.

[0043] Combined with reference Figures 1 to 4, the ice-making refrigeration device 10 may include an ice-making head 110. Exemplarily, the ice-making head 110 has a refrigerant pipeline, which can be connected to the compressor through an external refrigerant circulation pipeline 420. The ice-making head 110 can be considered as an evaporator. The ice-making head 110 can generally include a main pipeline 111 and a plurality of ice-hanging ends 112 arranged on the main pipeline 111. The plurality of ice-hanging ends 112 extend downward from the main pipeline 111 respectively. The plurality of ice-hanging ends 112 are spaced apart from each other. The refrigerant pipeline is mainly located in the main pipeline 111, and the plurality of ice-hanging ends 112 can be heat-exchanged with the main pipeline 111. Optionally, the refrigerant pipeline can also extend from the main pipeline 111 to the plurality of ice-hanging ends 112. When the ice-making head 110 is working, ice cubes 700 can be formed on the plurality of ice-hanging ends 112 respectively, and the size of the ice cubes 700 on the plurality of ice-hanging ends 112 can be controlled by controlling the working time of the compressor. If necessary, the ice cubes 700 on the adjacent ice hanging ends 112 can be prevented from contacting each other, so that a small ice cube is formed on each ice hanging end 112. Of course, if necessary, the ice cubes 700 on multiple ice hanging ends 112 can also be connected into a whole block. The compressor has a lower refrigeration temperature and higher efficiency, can quickly achieve ice making, and has low energy consumption. Of course, in some embodiments, it is not excluded that the ice making head adopts electronic refrigeration, absorption refrigeration and other methods for refrigeration.

[0044] The ice-making head 110 may have an ice-making mode for making ice cubes 700 and a refrigeration water mode for making cold water. A limiting valve (not shown) may be provided on the refrigerant circulation pipeline 420. In the refrigeration water mode, the limiting valve may reduce the refrigeration power of the ice-making head 110, so that the ice-making head 110 will not lower the water temperature very low in a short time when contacting the same amount of water, so as to only cool the water in contact with it without condensing into ice cubes 700. Alternatively, the limiting valve may make the temperature of the ice-making head 110 have a lower limit greater than 0°C, so that the water will not be frozen into ice cubes 700. The mode of controlling the ice-making head 110 may also be achieved by adjusting the power of the compressor. In some embodiments, the ice-making refrigeration device 10 uses a variable frequency compressor, and the power of the compressor can be controlled by changing the frequency of the AC power supplied to the compressor, thereby achieving power control of the ice-making head 110. In other words, for some exemplary embodiments of the ice-making refrigeration device 10, in the ice-making mode, the ice-making head 110 can freeze water into ice cubes 700, while in the cooling water mode, water is generally not frozen.

[0045] For the ice-making refrigeration device 10 of other exemplary embodiments, when the ice-making head 110 works in the cooling water mode, ice cubes 700 of a certain size can be frozen in the cold water, and the ice cubes 700 are mixed with the remaining cold water and provided to the user as ice water. Alternatively, the ice-making head 110 can work intermittently and make ice cubes 700, and in the intervals between the ice-making head working, the made ice cubes 700 melt in the water to produce cold water. This can prevent the ice cubes 700 from being too large in volume and hindering the process of cooling water. In short, the ice-making refrigeration device 10 can definitely make ice cubes 700 in the ice-making mode, and can make ice cubes 700 in the cooling water mode, or it can not make ice cubes 700, as long as cold water can be provided.

[0046] The ice-making refrigeration device may include a water supply circuit for providing water required for making ice cubes to the ice-making head 110. The ice-making refrigeration device 10 may provide a water source to the ice-making head 110 by any suitable method. For example, a water spraying device (not shown) may be provided inside or around the ice-making head 110, and the water spraying device may spray water onto the ice-making head 110, thereby obtaining ice cubes 700 or cold water. Alternatively, the ice-making refrigeration device 10 may include an ice-making water storage box 120 (described in detail below) provided below the ice-making head 110, and the ice-making head 110 is immersed in water, thereby obtaining cold water or ice cubes 700.

[0047] The ice-making refrigeration device 10 may include a cold water tank 200, which may be disposed below the ice-making head 110. The cold water tank 200 may be used to collect the residual cold water in the ice-making mode, or may be used to collect the cold water produced in the refrigeration water mode. Exemplarily, the ice-making head 110 may be disposed in the cold water tank 200 to collect the cold water flowing through the ice-making head 110. Exemplarily, the top of the cold water tank 200 may have an open opening, the ice-making head 110 is located outside the cold water tank 200 and directly above the cold water tank 200, and the cold water flowing through the ice-making head 110 may fall into the cold water tank 200 through the opening. Exemplarily, a collection container may be provided directly below the ice-making head 110 for collecting the cold water flowing through the ice-making head 110. The collection container is communicated with the cold water tank 200. In this way, the position of the cold water tank 200 may not be restricted. Those skilled in the art may select as needed. The ice cubes 700 produced by the ice making head 110 can be directly delivered to the user through the ice delivery device, or can fall into the cold water tank 200 and then be delivered to the user through the ice delivery device. For example, the ice cubes 700 can be provided to the user alone, or can be provided to the user after forming an ice-water mixture with cold water. Figure 2 In the illustrated embodiment, ice cubes 700 may be provided to the user through the ice outlet 201 .

[0048] In other embodiments, the ice delivery device may not be provided. Specifically, the top opening or the interior of the cold water tank 200 may be provided with a filter, such as a filter, a baffle, a sieve plate, etc. The filter can prevent the ice cubes 700 from falling into the cold water tank 200, and only allow cold water to enter the cold water tank 200, so that the ice cubes 700 can be collected on the filter. In the case where the ice-making head 110 does not make ice cubes 700, but only makes cold water, the water cooled by the ice-making head 110 can all enter the cold water tank 200. In the case where the ice-making head 110 makes ice cubes 700, the ice cubes 700 can stay on the filter to drain after being blocked, or slide along the filter to the ice outlet 201, thereby providing the user with relatively dry ice cubes 700. All the cold water remains in the cold water tank 200 and is provided to the user through a valve, a faucet or a water pump.

[0049] In the above technical scheme, the ice-making refrigeration device 10 can provide an ice-making mode and a cooling water mode using the same ice-making head 110. In the ice-making mode, the ice-making head 110 can make ice cubes 700. If the ice-making process produces residual cold water that has not condensed into ice, it can be collected in the cold water tank 200. In the cooling water mode, the ice-making head 110 can make cold water and store the produced cold water in the cold water tank 200. When cold water is needed, it can be directly provided to the user from the cold water tank 200. Thus, the same ice-making head 110 can be used to provide both ice cubes 700 and cold water, thereby greatly reducing the cost of the ice-making refrigeration device 10, simplifying the layout and control logic of the pipeline, and enhancing reliability. The interior of the equipment using the ice-making refrigeration device 10 is more concise, and there is no need to leave a large space for the ice-making refrigeration device 10 and the external pipeline, and the volume can be more compact.

[0050] Exemplarily, the cold water tank 200 may further include a cold water tank outlet 250 (see Figure 1 ). A water pump (not shown) may be provided on the water supply waterway, and the water inlet of the water pump may be connected to the cold water tank outlet 250 of the cold water tank 200. The water pump is used to pump the water in the cold water tank 200 to the ice making head 110. Optionally, the cold water tank 200 may also include a cold water tank inlet 240 for receiving purified water. Since the cold water tank 200 contains water at a relatively low temperature, the cold water is extracted from the cold water tank 200 by the water pump for ice making, which can shorten the time required for ice making and reduce energy consumption. In the illustrated embodiment, the cold water tank inlet 240 and the cold water tank outlet 250 are both arranged at the bottom of the cold water tank 200. In other embodiments, the cold water tank inlet 240 and the cold water tank outlet 250 may also be arranged at other positions of the cold water tank 200.

[0051] Exemplarily, the ice-making refrigeration device 10 may further include a temperature sensor 130, which is used to detect the water temperature in the cold water tank 200. The temperature sensor 130 may include any device that is currently available or may appear in the future and can detect temperature, including but not limited to a thermocouple, a thermal resistor, an infrared temperature sensor, etc. The temperature sensor 130 can directly or indirectly detect the water temperature in the cold water tank 200. For example, the temperature sensor 130 can be arranged in the cold water tank 200 to directly detect the water temperature in the cold water tank 200. The temperature sensor 130 can also be arranged on the path of the water flow from the ice-making head 110 to the cold water tank 200, so as to obtain the temperature of the cold water entering the cold water tank 200. The temperature sensor 130 can also be arranged at the water outlet of the cold water tank 200, and when the user takes water, the water temperature in the cold water tank 200 can be obtained. The temperature sensor 130 can obtain the temperature of the cold water and generate cold water temperature information in the form of an analog signal or a digital signal.

[0052] The ice-making refrigeration device 10 may further include a controller, which is used to control the pumping rate of the water pump according to the water temperature. The controller may be constructed using electronic components such as a timer, a comparator, a register, a digital logic circuit, or may be implemented using a processor chip such as a single-chip microcomputer, a microprocessor, a programmable logic controller (PLC), a digital signal processor (DSP), a field programmable gate array (FPGA), a programmable logic array (PLA), an application-specific integrated circuit (ASIC), and its peripheral circuits.

[0053] like Figure 1In the specific embodiment shown, the temperature sensor 130 can be arranged on the outer wall of the cold water tank 200 or in the cold water tank 200, and the detection part of the temperature sensor 130 is inserted into the water in the cold water tank 200. The side wall of the cold water tank 200 can be reserved with a hole, and the detection part of the temperature sensor 130 is inserted into the cold water tank 200 from the hole to detect the water temperature. In some embodiments, the temperature sensor 130 can also extend into the cold water in the cold water tank 200 from an existing opening. When the controller determines that the temperature of the cold water is higher than the upper limit of the cold water temperature threshold according to the cold water temperature information detected by the temperature sensor 130, the ice-making head 110 can be controlled to be in the cooling water mode. In the cooling water mode, the water pump can be controlled to pump water to the ice-making head 110 at an appropriate pumping rate, and the cooled cold water flows back to the cold water tank 200. In this way, the water temperature in the cold water tank 200 can be reduced until the water temperature represented by the cold water temperature information is lower than the lower limit of the cold water temperature threshold, and the water pump is controlled to stop pumping, that is, the pumping rate is zero. In some embodiments, the controller may also control the pumping rate in sections or continuously according to the cold water temperature represented by the cold water temperature information. For example, if the water temperature in the cold water tank 200 is high, the controller may control the water pump to pump water to the ice making head 110 at a higher pumping rate; as the water temperature in the cold water tank 200 gradually approaches the lower limit of the cold water temperature threshold, the pumping rate of the water pump may be reduced until the pumping is completely stopped. The refrigeration power of the ice making head 110 may be constant, and ice cubes 700 may be generated in the process of cooling water. A larger pumping rate may cause a large amount of water with a higher temperature to be poured onto the ice cubes 700. When the ice making head 110 stops working, the ice cubes 700 may melt back into cold water more quickly, so that the water temperature in the cold water tank 200 is quickly reduced to below the lower limit of the cold water temperature threshold.

[0054] In another embodiment not shown, a temperature sensor can be arranged on the path where water flows into the cold water tank. The water flow rate flowing into the cold water tank is usually fixed, and thus the water temperature in the cold water tank can be roughly determined according to the temperature of the water flowing into the cold water tank. According to the situation that the water temperature in the cold water tank measured in the laboratory rises over time, the water pump in the cold water tank can be regularly sent to the ice making head to cool down again. In another embodiment not shown, the ice making refrigeration device can intermittently send the water pump to the ice making head for circulation to detect the current water temperature in the cold water tank, and start the ice making head when detecting that the water temperature is higher than the upper limit of the cold water temperature threshold. Thus in the above-mentioned embodiment, the temperature sensor can simultaneously detect the temperature of the water in the cold water tank, and the temperature of the cold water after the ice making head cools down, so that the temperature can be accurately controlled.

[0055] In summary, by detecting the water temperature in the cold water tank 200 and controlling the pumping rate of the water pump, the water temperature in the cold water tank 200 can be prevented from being too high, thereby satisfying the user's demand for cold water.

[0056] Exemplarily, the controller of the ice-making refrigeration device 10 is used to control the refrigeration power of the ice-making head 110. The ice-making head 110 has an ice-making mode and a cooling water mode under the action of the controller. Figure 10-11 , the ice-making head 110 is connected to the compressor 410 and the condenser 440 through the refrigerant circulation pipeline 420 (only part of the pipeline is shown in the figure). The refrigerant absorbs heat and evaporates in the ice-making head 110, and condenses and releases heat at the condenser 440 under the action of the compressor 410, thereby reducing the temperature of the ice-making head 110. Exemplarily, the condenser 440 may include a coiled condensing tube 441 and fins arranged on the surface of the condensing tube 441. The refrigerant can be condensed in the condensing tube 441, and the coiled condensing tube 441 and the fins can provide a larger surface area, so that the heat dissipation efficiency is higher. A mode switching solenoid valve (not shown) may be provided on the refrigerant circulation pipeline 420, and the mode switching solenoid valve may be connected in parallel with part of the condensing tube 441. When the mode switching solenoid valve is working, part of the refrigerant with a higher temperature can be directly returned to the ice-making head 110 without condensation in the condenser 440, thereby reducing the refrigeration power of the ice-making head 110. In the embodiment where the ice-making refrigeration device 10 includes a variable frequency compressor, the variable frequency compressor is powered by an AC power supply. When the power frequency decreases, the power of the variable frequency compressor decreases accordingly. As a result, the flow rate of the refrigerant in the refrigerant circulation pipeline 420 decreases, thereby reducing the refrigeration power of the ice-making head 110. Using a lower refrigeration power can prevent water from freezing on the ice-making head 110, and the ice-making head 110 does not need to work intermittently to prevent the volume of the ice cubes 700 from being too large. This simplifies the control logic and avoids the ice cubes 700 from obstructing the refrigeration water. Reducing the power of the ice-making head 110 can also reduce the noise when the compressor 410 is working.

[0057] Exemplarily, the controller is also used to control the refrigeration power of the ice-making head 110 according to the water temperature in the cooling water mode. It is easy to understand that when the amount of water in the cold water tank 200 is the same, the higher the water temperature therein, the greater the refrigeration capacity required to reduce it to the lower limit of the cold water temperature threshold. Appropriately changing the refrigeration power of the ice-making head 110 according to the water temperature can shorten the time required for cooling water. For example, the water in the cold water tank 200 is water at room temperature that has just been replenished. At this time, it can be cooled with a larger refrigeration power so that it quickly reaches the lower limit of the cold water temperature threshold. The upper limit of the cold water temperature threshold is lower than the room temperature, so when the water temperature rises to above the upper limit of the cold water temperature threshold, it can be cooled with a smaller power, thereby reducing the noise of the ice-making refrigeration device 10 working, and it is more energy-efficient.

[0058] In ice making mode, if water is poured onto the ice making head 110, most of the water will flow back to the cold water tank 200 along the ice making head 110, generating water flowing noise. Moreover, the ice cubes produced are usually stalactite-shaped, very long, sharp and easy to break. Such ice cubes are not convenient to use and the user experience is not good. Therefore, if Figure 3-Figure 7 As shown, the ice-making refrigeration device 10 may further include an ice-making water storage box 120. The top of the ice-making water storage box 120 has an opening, and the ice-making water storage box 120 has a working position. When the ice-making water storage box 120 is in the working position, the ice-making head 110 extends into the ice-making water storage box 120 through the opening, see Figure 3 and Figure 5 . Water can be contained in the ice-making water storage box 120, and the ice-making head 110 extends below the water surface, thereby forming ice cubes 700 on the ice hanging end 112. The length and width of the ice cubes 700 thus obtained are more appropriate, and the noise of running water will not be generated all the time, and the user experience is better. In the process of cooling water, water can also be injected into the ice-making water storage box 120 and cooled by the ice-making head 110. The ice-making head 110 can discharge the water in the ice-making water storage box 120 into the cold water tank 200 after a predetermined cooling time or after cooling to a predetermined temperature, without generating continuous noise of running water.

[0059] For example, the ice making water storage box 120 may also have an ice dropping position, and when the ice making water storage box 120 is in the ice dropping position, it is outside the falling path of the ice cubes 700. The ice making refrigeration device may also include a driver 140, and the ice making water storage box 120 may be moved between the working position and the ice dropping position under the action of the driver 140. Figure 3-Figure 6 In the illustrated embodiment, the driver 140 may include a motor, and the ice making water storage box 120 may pivot between a working position and an ice making position around the rotating shaft of the motor. It is easy to understand that the ice making head 110 is inserted into the opening of the ice making water storage box 120, and the generated ice cubes 700 are also in the ice making water storage box 120. After ice making is completed, the ice making head 110 can be, for example, in a defrosting mode or the above-mentioned refrigeration water mode, so that the temperature of the ice making head 110 increases. This achieves that the part of the ice cube 700 in contact with the ice making head 110 melts and then demolds. The demolded ice cube 700 can be poured together with the residual cold water in the ice making water storage box 120. The ice cube 700 collides with the cold water, which may cause more water to be provided to the user from the ice outlet. In the case where the user only wants the ice cube 700, the residual cold water seriously affects the user's experience, and this part of the cold water will also be wasted. Preferably, the ice making water storage box 120 can be removed first, and then the ice cube 700 is demolded. Thus, relatively dry ice cubes 700 can be provided to the user, and the user experience is good.

[0060] In some embodiments not shown, the ice-making water storage box can be moved to the ice-dropping position by other suitable means. For example, the driver may include structures such as a linear motor and an electric cylinder. The ice-making water storage box can reach the ice-dropping position by vertical and horizontal movement, and avoid the space under the ice-making head. After the ice falls, the ice-making water storage box may not discharge the residual cold water into the cold water tank, but directly return to the working position to continue making ice. It is also possible to discharge the residual cold water into the cold water tank and then return to the working position for the next ice-making. Or before the ice cubes 700 are demolded, the residual cold water is discharged into the cold water tank. The ice-making water storage box can drain water through mechanisms such as valves and baffles, or it can pour water into the cold water tank by flipping or the like.

[0061] In the above technical solution, by moving the ice making water storage box 120 to the ice dropping position, the ice cubes 700 can be directly dropped from the ice making head 110, and the ice cubes 700 are relatively dry. The ice making water storage box 120 can also put the residual cold water into the next ice making, or pour the residual cold water into the cold water tank 200 before and after the ice cubes 700 are demolded, thereby reducing the waste of residual cold water.

[0062] Exemplarily, the ice making water storage box 120 is rotatably arranged between the working position and the ice dropping position around a horizontal axis under the action of the driver 140. When the ice making water storage box 120 is in the ice dropping position, the opening is tilted or downward to pour out the water contained in the ice making water storage box 120. Figure 4 and Figure 6 shown. Figure 3 and Figure 4 The cross-sectional views of the ice-making refrigeration device 10 are respectively shown when the ice-making water storage box 120 is in the working position and the ice-dropping position. Figure 5 and Figure 6 The three-dimensional diagram of the ice-making refrigeration device 10 without the cold water tank 200 is shown when the ice-making water storage box 120 is in the working position and the ice-dropping position. It can be seen that when the ice-making water storage box 120 is in the working position, a certain amount of water can be contained. The ice-making head 110 can be immersed in water to achieve ice making or cooling water. The ice-making water storage box 120 pivots around the horizontal axis, and the space occupied before and after the pivoting can be almost unchanged, thereby effectively reducing the volume of the ice-making refrigeration device 10. The common motor movement mode is the rotation of the rotating shaft. The ice-making water storage box 120 is rotated between the working position and the ice-dropping position by a rotating mode, which can simplify the design and reduce the difficulty of motor selection. When the ice-making water storage box 120 is in the ice-dropping position, the water in the ice-making water storage box 120 will be poured to the bottom, and the bottom of the ice-making head 110 is no longer blocked by the ice-making water storage box 120. Thus, through a motor and a relatively simple structure, it is possible to simultaneously pour cold water into the cold water tank 200 and allow the ice cubes 700 to fall without being hindered by the ice making water storage box 120. The control logic is also simpler and the reliability is higher.

[0063] For example, when the ice-making refrigeration device 10 includes an ice-making water storage box 120, the water outlet of the water pump can be connected to the water inlet of the ice-making water storage box 120. When the water temperature in the cold water tank 200 is high, the water pump can pump water to the ice-making water storage box 120 for cooling, and then enter the cold water tank 200 from the ice-making water storage box 120, and the cycle continues until the water temperature in the cold water tank 200 reaches a threshold.

[0064] like Figure 4 and Figure 6 As shown, the water outlet of the water pump can be connected to a water supply pipe 150, and the water supply pipe 150 extends from the opening of the ice-making water storage box 120 to the bottom of the ice-making water storage box 120, so that the water outlet of the water pump is connected to the ice-making water storage box 120. The bottom of the ice-making water storage box 120 is provided with a downwardly concave avoidance groove 125, and the outlet of the water supply pipe 150 faces the avoidance groove 125. The avoidance groove 125 can make the depth of the ice-making water storage box 120 deeper at this location, so that the outlet of the water supply pipe 150 is farther from the bottom of the avoidance groove 125, the output water flow is less obstructed, and the water flow is not easy to splash out from the opening along the bottom wall of the ice-making water storage box 120. Exemplarily, the avoidance groove 125 can be formed on the bottom wall of the ice-making water storage box 120, and when the ice-making water storage box 120 is in the working position, the bottom of the avoidance groove 125 is lower than other positions of the bottom wall of the ice-making water storage box 120. The end of the water supply pipe 150 can extend to the top of the avoidance groove 125 and be slightly higher than the bottom wall of the ice-making water storage box 120. As a result, the water flow of the water supply pipe 150 first enters the avoidance groove 125, and then fills the entire ice-making water storage box 120 through the avoidance groove 125. The water outlet of the water supply pipe 150 can be as close to the bottom wall as possible. On the one hand, noise can be reduced during the water supply process and almost no bubbles will appear in the water, so that the ice cubes 700 and cold water produced are of better quality. On the other hand, in the ice-making mode, the water entering from the bottom of the ice-making water storage box 120 will not be blocked by the ice cubes 700, nor will it collide with the water surface to splash out. Exemplarily and not restrictively, in the refrigeration water mode, if a solution of continuously injecting water into the ice-making water storage box 120 is adopted, water with a higher temperature can enter from the bottom of the ice-making water storage box 120. In this way, the cold water that sinks to the bottom of the ice-making water storage box 120 due to its large specific gravity can be pushed out, so that the cold water with a lower temperature overflows the ice-making water storage box 120 and flows into the cold water tank 200 below.

[0065] Thus, the ice-making refrigeration device 10 can reduce the waiting time of the user and reduce energy consumption when making ice. When the water temperature in the cold water tank 200 is higher than the threshold, the refrigeration can be circulated so that the water temperature always meets the requirements.

[0066] Exemplarily, the ice-making refrigeration device 10 may further include an ice storage box 40. The ice cubes 700 may be temporarily stored in the ice storage box 40, and the user may remove the ice storage box 40 to transfer the ice cubes 700 to a desired location. In other embodiments, the ice storage box 40 is not removable, and the user may take the ice cubes 700 from the opening of the ice storage box 40. Figures 3 to 6 As shown, the ice-making refrigeration device 10 may include an ice chute 50, which may be disposed directly below the ice-making head 110 and used to receive ice cubes 700. The ice chute 50 is located directly below the ice-making head 110, so that the ice cubes formed on the ice-making head 110 can fall directly onto the ice chute 50 under the action of gravity. To achieve this purpose, the orthographic projection of the ice cubes on the ice-making head 110 on the horizontal plane must fall within the orthographic projection of the ice chute 50 on the horizontal plane, so that the ice chute 50 can receive the ice cubes 700.

[0067] The directional terms "directly above" and "directly below" used in this article both mean that the orthographic projections of the two on the horizontal plane at least partially overlap, and those skilled in the art can determine the orthographic projection relationship between the two based on the functions of the components involved.

[0068] The ice conveying channel 50 can extend downwardly and tilted, and the lower end of the ice conveying channel 50 is aligned with the ice inlet 41 of the ice storage box 40 (see Fig.10 ). The lower end of the ice chute 12 being aligned with the ice outlet 13 may include: taking a horizontal line along the width direction of the lower end of the ice chute 12, and the projection of the lower end of the ice chute 12 on this horizontal line completely falls into the horizontal projection of the ice outlet 13 on this line. The ice cubes can all fall into the ice outlet 13 along the ice chute 12 without being hindered by the connection between the ice outlet 13 and the ice chute 12. The ice inlet 41 of the ice storage box 40 can be aligned with the ice outlet 201 on the cold water tank 200. For example, the projection of the ice inlet 41 of the ice storage box 40 on the ice outlet 201 on the cold water tank 200 is completely included by the ice outlet 201. Thereby, the ice cubes 700 can slide into the ice storage box 40 through the ice outlet 201 and the ice inlet 41 in sequence under the action of their own weight, without the need to set a driving device, with a simple structure and a more compact size. The ice chute 50 is provided with a drain hole 51 (see Figures 5 and 6), the drain hole 51 is connected to the cold water tank 200. When the ice delivery channel 50 is arranged in the cold water tank 200, the water passing through the drain hole 51 can directly fall to the bottom of the cold water tank 200. In the process of ice cubes 700 and some residual cold water sliding down the ice delivery channel 50 to the ice storage box 40, the cold water can return to the cold water tank 200 through the drain hole 51, reducing the waste of cold water. At the same time, the relatively dry ice cubes 700 can enter the ice storage box 40. The dry ice cubes 700 are not easy to adhere, and are less likely to breed bacteria. They can be stored for a longer time and have a relatively good taste. The bottom of the ice storage box 40 can be provided with a drain port (not shown). The cold water not collected by the drain hole 51 and the water generated by the melting of the ice cubes 700 can be discharged to the sewer or other wastewater collection container through the drain port of the ice storage box 40, thereby avoiding the accumulation of water in the ice storage box 40, and also preventing the breeding of bacteria, so that the ice cubes 700 are dry. In order to extend the storage time of the ice cubes 700, the ice storage box 40 can be made of a heat-insulating material, or can be coated or lined with a heat-insulating material, thereby reducing the heat exchange between the ice cubes 700 and the outside.

[0069] For example, see Figures 5 and 6 , the upper end of the ice delivery channel 50 may be provided with a water outlet 52, which is in communication with the cold water tank 200. The edge of the opening of the ice making water storage box 120 may be provided with an overflow nozzle 121, which is in communication with the water outlet 52 and forms a reflux path to the cold water tank 200 via the overflow nozzle 121 and the water outlet 52. As described above, the water required for ice making and refrigeration water is pumped from the cold water tank 200 to the ice making water storage box 120 by a water pump. In order to ensure that the part of the ice making head 110 immersed in the water is as large as possible, the ice making water storage box 120 can be completely filled. Preferably, it is possible to ensure that a sufficient amount of water enters the ice making water storage box 120 by controlling the working time of the water pump. Excess water can overflow through the overflow nozzle 121, so that there is no need to accurately control the amount of water entering the ice making water storage box 120, thereby simplifying the control logic and reducing the control difficulty.

[0070] Exemplarily, along the horizontal axis, the ice making water storage box 120 has a first end 122 and a second end 123 opposite to each other, and the overflow nozzle 121 is located at the first end 122. Figure 5 and Figure 6As shown, the first end 122 of the ice-making water storage box 120 is located above the water outlet 52. The second end 123 can be located above the ice storage box 40. The overflow nozzle 121 is arranged above the water outlet 52, and the water overflowing from the ice-making water storage box 120 can flow into the water outlet 52 through the overflow nozzle 121, and then return to the cold water tank 200. Exemplarily but not restrictively, the overflow nozzle 121 can be a groove arranged at the edge of the opening of the ice-making water storage box 120. When the water level in the ice-making water storage box 120 reaches the height of the overflow nozzle 121, it will overflow from the overflow nozzle 121 first, and will not overflow from other parts of the ice-making water storage box 120. In this way, it can be ensured that almost all of the overflowed water flows into the water outlet 52, and a large amount of water is prevented from flowing to the ice storage box 40 through the ice delivery channel 50, resulting in the water drain hole 51 not being able to drain the water into the cold water tank 200 in time, so that water accumulates in the ice storage box 40. At the same time, the ice conveying chute 50 will not be overly wet due to the overflowing water, and the ice cubes 700 will remain relatively dry after entering the ice storage box 40 through the ice conveying chute 50, and there will be no risk of the ice cubes 700 contacting the wet ice conveying chute 50 and sticking.

[0071] like Figure 7 As shown, illustratively, a guide rib 124 may be provided on the inner wall of the ice-making water storage box 120. The guide rib 124 extends from the first end 122 to the second end 123, and the guide rib 124 has a third end 124A corresponding to the first end 122 and a fourth end 124B corresponding to the second end 123. When the ice-making water storage box 120 is in the working position, the guide rib 124 is tilted upward from the fourth end 124B to the third end 124A. Because the opening of the ice-making water storage box 120 in the working state faces upward, the third end 124A of the guide rib 124 is closer to the opening edge of the ice-making water storage box 120. When the ice-making water storage box 120 is in the ice-falling position, the third end 124A of the guide rib 124 is located above the water outlet 52. During the rotation of the ice making water storage box 120 from the working position to the ice dropping position, the water flow can be gathered to the opening edge of the ice making water storage box 120 toward the third end 124A under the action of the guide ribs 124, and then poured downward from the edge. The poured water can quickly flow into the cold water tank 200 through the water outlet 52, and will not flow to the ice storage box 40 along the ice conveying channel 50, causing the ice conveying channel 50 to be wetted by water. In this way, it can be ensured that the ice cubes 700 can remain dry after falling and smoothly fall into the ice storage box 40, and will not be wetted and stick to each other.

[0072] Exemplarily, a receiving groove 53 may be provided at the upper end of the ice delivery channel 50, and the receiving groove 53 extends in a horizontal direction perpendicular to the horizontal axis, and the water outlet 52 is located at the bottom of the receiving groove 53. When the ice-making water storage box 120 is in any position between the working position and the ice-dropping position, the overflow nozzle 121 is located above the receiving groove 53. As described above, when the ice-making water storage box 120 is in the ice-dropping position, a large amount of cold water in the refrigeration water mode in the box or the cold water remaining in the ice-making mode will converge to the first end 122 of the ice-making water storage box 120 under the action of the guide rib 124, and be poured into the water outlet 52 below. The flow rate of the water outlet 52 may not be enough to allow a large amount of cold water to pass immediately, so a receiving groove 53 may be provided for buffering. Part of the cold water can be temporarily stored in the receiving groove 53, and then all flows into the cold water tank 200 through the water outlet 52. The vertical wall of the receiving groove 53 can prevent the pouring water from splashing onto the portion of the ice delivery channel 50 extending to the ice storage box 40, and then flowing into the ice storage box 40 along the ice delivery channel 50 over the drain hole 51. The width of the receiving groove 53 perpendicular to the horizontal direction is not very large, generally smaller than the width of the ice cube 700, and is set at a position away from the ice making head 110. In this way, when the ice cube 700 falls, it is almost impossible to get stuck in the receiving groove 53. The water outlet 52 can be a plurality of holes separated from each other set at the bottom of the receiving groove 53, or it can be one or more slits extending along the horizontal direction, which can allow cold water to pass through.

[0073] According to another aspect of the present application, a water purifier is provided. The water purifier may include an output port and any of the aforementioned ice-making refrigeration devices 10. The output port is connected to the ice-making head 110, and the ice cubes 700 made by the ice-making head 110 are output to the outside of the water purifier via the output port. The water purifier may include a housing 20 and components that implement other functions, such as a heating module 300 for providing hot water, a housing 20 that shields and protects the internal structure, and partitions and brackets disposed inside the housing 20 to separate different areas and provide support for various components. Exemplarily, the output port may include an opening disposed on the housing 20, which may be aligned with the ice outlet 201 mentioned above, and the ice cubes 700 may reach the outside of the water purifier through the output port. The output port may also be connected to a cold water tank 200, and the cold water in the cold water tank 200 is output to the outside of the water purifier via the output port, so that the water purifier may also provide cold water to the user. A sterilization device 210 such as an ultraviolet lamp may be disposed at the bottom of the cold water tank 200 (see Figure 1 ), to prevent bacteria from growing in the cold water tank 200. The outlet can be a general term for the outlets, holes, openings, etc. provided on the housing 20 of the water purifier for providing liquids and solids, and can be separated from each other or provided together. Thus, the housing 20 of the water purifier can provide support and protection for the ice-making refrigeration device 10 and other structures, and at the same time, a window for outputting products such as ice cubes and cold water is provided, which is overall beautiful and practical, and the structure is firm and reliable.

[0074] Exemplarily, the water purifier may further include a raw water supply device. The raw water supply device may include a water tank 500 (see Figures 8 to 9 ), tap water interface, self-priming pump, etc., for storing raw water, connecting tap water, or extracting raw water from raw water containers such as buckets. The water purifier may also include a filtering device, which has a raw water inlet and a clean water outlet. The raw water inlet is connected to the raw water supply device. Since the raw water may contain dust, rust, residual chlorine, bacteria, heavy metals, etc. due to pollution during storage or residual chemicals in tap water treatment, and rust in pipes, the raw water can be treated by the filtering device. The filtering device may include a filter element 600, which may include filter elements such as activated carbon filter elements, PP filter elements, ceramic filter elements, resin filter elements, ultrafiltration filter elements, nanofiltration filter elements, reverse osmosis filter elements, and composite filter elements composed of one or more of the filter elements. For nanofiltration filter elements and reverse osmosis filter elements, appropriate pressure is required when they work, so the water purifier may also include a booster pump. The filter element 600 can filter the raw water to remove harmful bacteria, heavy metals and other impurities therein, and provide users with high-quality clean water. The purified water outlet can be connected to the cold water tank 200, so that there are almost no bacteria and other impurities in the water used for ice making by the ice-making refrigeration device 10, the cold water and ice cubes are of higher quality and can be stored for a longer time.

[0075] The filter element 600 may include a reverse osmosis filter element, the pore size of which is 0.1 micron (0.5 millionths) of a hair, and the number of bacteria and viruses that are generally invisible to the naked eye is 10 times that of the filter element. 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 outlet of the concentrated water pipe, providing users with high-quality purified water. The water purifier may include a concentrated water discharge device, and the concentrated water outlet is connected to the concentrated water discharge device. The concentrated water discharge device may be integrated into the water tank 500. For example, the concentrated water may be directly discharged into the water tank 500 to mix with the raw water, or a partition may be provided in the water tank 500 to separate the raw water and the concentrated water. Of course, a separate water tank may also be provided to store the concentrated water. Optionally, the concentrated water discharge device may also include a drain pipe, and the user may connect the drain pipe to the sewer to directly discard the concentrated water containing more impurities. The daily water production of the reverse osmosis filter element is positively correlated with its price, so the filter element 600 may use a small flux filter element with a daily water production of no more than 400 gallons. On the premise of meeting the basic needs of users, the cost can be greatly reduced and the size of the water purifier can be reduced.

[0076] Exemplarily, at least one of the raw water supply device and the concentrated water discharge device is a container. Figure 8 and Fig. 9The water purifier may include a water tank 500, which may be used to store raw water. The user can remove the water tank 500 and only carry the water tank 500 to a water source such as tap water for filling, without having to carry the entire water purifier. The water tank 500 may be installed to the water purifier body in the lateral direction, and the size of the water tank 500 in the lateral direction is not greater than half of the size of the water purifier in the lateral direction. The water purifier may be placed in a relatively narrow space such as a cabinet, with only a small gap around it. The smaller size of the water tank 500 in the lateral direction allows it to be taken out through a smaller gap. The user can also save effort when disassembling and assembling the water tank. The water purifier may include a concentrated water pipe, which can discharge the concentrated water of the water purifier to an external concentrated water container such as a bucket, so that the user can use the concentrated water to mop the floor, flush the toilet, etc., saving water. The concentrated water pipe can also be directly connected to the sewer. For situations where it is inconvenient to connect an external concentrated water container or sewer, illustratively, the water purifier can discharge the concentrated water into the water tank 500. At this time, the water tank 500 can be used as a storage container for raw water and as a storage container for concentrated water at the same time. In some embodiments not shown, the water purifier may also be connected to a tap water pipe, and the tap water enters the water purifier as raw water, and can be buffered by the water tank 500, or can directly enter the filter device without passing through the water tank 500. At this time, the concentrated water can be discharged into the water tank 500, and the user does not need to set up a concentrated water pipe, and can also store the concentrated water for daily use, thereby reducing the waste of water resources. The water purifier can also be provided with a separate raw water tank and a concentrated water tank, and the raw water and concentrated water do not interfere with each other, thereby extending the service life of the filter element 600.
