Description

Technical Field

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

[0002] In order to meet people's different drinking water needs, many household water purifiers have begun to provide cold water. Such water purifiers usually include a cold tank for storing cold water. In order to reduce the water temperature in the cold tank, some water purifiers are equipped with a refrigeration circulation system including a compressor, a condenser and an evaporator. The cold tank is cooled by the circulation of the refrigerant in the refrigeration circulation system.

[0003] In existing household water purifiers that use a refrigeration cycle system to produce cold water, the evaporator is usually arranged around the outside of the cold tank, which affects the refrigeration efficiency. In existing commercial water purifiers, there are attempts to arrange the evaporator inside the cold tank, but the evaporator is arranged on the upper part of the inner wall of the cold tank.

[0004] For commercial water purifiers, they require a large amount of cold water, so the cooling tank is kept full of water for a long time, and the evaporator can be immersed in water for cooling. However, for household water purifiers, every time water is taken, water is immediately stored in the cooling tank, which will cause the compressor to start and stop frequently, and it will also generate noise and increase energy consumption. 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. The water purifier includes: a cold tank and a refrigeration cycle system. The refrigeration cycle system includes a compressor, a condenser and an evaporator. The outlet of the evaporator is connected to the inlet of the compressor through a first pipeline, the outlet of the compressor is connected to the inlet of the condenser, and the outlet of the condenser is connected to the inlet of the evaporator through a second pipeline. The evaporator is arranged in the cold tank and located at the lower part of the cold tank, and is used to cool the water in the cold tank. The compressor and the condenser are arranged outside the cold tank.

[0006] Since the evaporator is arranged in the cold tank, the refrigeration efficiency can be improved. Moreover, by placing the evaporator inside the cold tank, the cold water can completely fill the space around the evaporator, and the volume occupied by the evaporator can be significantly reduced compared to being arranged outside the cold tank. This is very important for household water purifiers, especially desktop water purifiers. In addition, the evaporator in the present application is located at the lower part of the inner tank, and the refrigeration can be maintained by only ensuring that the lower part of the cold tank is submerged in water, and the requirements for the water level in the cold tank are relatively low. In the case of a small amount of water, water can be added to the cold tank when the water level in the cold tank is lower than the lower limit of the liquid level, so that the compressor can be avoided from starting and stopping frequently. For some types of water purifiers, it may also include other functional modules such as ice making modules. Therefore, the upper space of the cold tank is used to place such functional modules of the water purifier, and the upper limit of the liquid level is located at the top of the cold tank so that it can be completely used to store cold water. This type of cold tank can be used, so the cold tank is more compatible.

[0007] Exemplarily, the top of the cold container has an opening. The first pipeline and the second pipeline are connected between the evaporator in the cold container and the compressor and the condenser outside the cold container through the opening. The evaporator can be installed inside the cold container through the opening, and the inside of the cold container can be cleaned through the opening on a daily basis. By using the opening, the first pipeline and the second pipeline are extended into the cold container, and sealing treatment is not required, thereby reducing the cost of the water purifier.

[0008] Exemplarily, the refrigeration cycle system also includes an ice-making head. The inlet of the refrigerant channel in the ice-making head is connected to the outlet of the condenser, and the outlet of the refrigerant channel is connected to the inlet of the compressor. The ice-making head is located in the cold tank and at the upper part of the cold tank. The ice-making head is used to make ice cubes thereon. The lower part of the cold tank can be used to store cold water, the evaporator is used to refrigerate the water stored in the cold tank, and the ice-making head at the upper part of the cold tank can be used to make ice. Therefore, the compressor and condenser of the refrigeration cycle system can be used to add an ice-making function to the water purifier, so that the needs of users can be better met without increasing the volume of the water purifier too much.

[0009] Exemplarily, an ice chute is also provided in the cold tank. The ice chute is located directly below the ice-making head and is used to receive ice cubes. The beverage purifier has an ice outlet, and the ice chute extends downwardly to the ice outlet. A drain hole is provided on the ice chute, and the drain hole is connected to the lower part of the cold tank. By providing an inclined ice chute, the ice cubes can automatically slide to the ice outlet under the action of their own gravity, thereby making the structure inside the cold tank relatively simple and reducing the occupied space. In addition, in the process of ice cubes and some residual cold water sliding along the ice chute to the ice outlet, the cold water can return to the cold tank through the drain hole, thereby reducing the waste of cold water.

[0010] Exemplarily, the water purifier further includes a water pump. The water inlet of the water pump is connected to the cold tank, and the water outlet of the water pump provides water for making ice cubes to the ice-making head. Since the ice-making head itself is located inside the cold tank, it is more convenient to directly transport the water stored in the cold tank to the ice-making head through the water pump for ice making, compared with transporting water from other parts of the water purifier such as the pure water tank. At the same time, the cold water stored in the cold tank is pure water with a lower temperature, and the amount of cold required in the process of making ice cubes is less, and the energy consumption of ice making is lower.

[0011] Exemplarily, the evaporator is an annular coil around a vertical axis. The structure of the annular coil can increase the contact area between the evaporator and water and improve the refrigeration efficiency. The annular coil can also be around a horizontal axis. However, this will increase the height of the coil. Therefore, when the water level in the cold tank is low, part of the coil may be exposed above the water surface, resulting in reduced refrigeration efficiency. In contrast, arranging the annular coil around the vertical axis can reduce the height to a certain extent. Moreover, a space for placing the sterilization component mentioned later can be formed in the area surrounded by the annular coil.

[0012] Exemplarily, the water purifier also includes a sterilization component. The sterilization component is arranged at the bottom of the cold tank and is surrounded by the annular coil. The water in the cold tank can be sterilized by controlling the operation of the sterilization component to prevent bacteria from growing in the cold tank. The sterilization component can be selected from ultraviolet lamps, ozone generators, etc. Taking the commonly used ultraviolet lamp as an example, since the upper part of the annular coil arranged around the vertical axis is open, the sterilization component is arranged there to irradiate most of the water upward. The evaporator basically does not block the ultraviolet rays, so the sterilization effect is better.

[0013] Exemplarily, a plurality of brackets spaced apart from each other around a vertical axis are provided at the bottom of the cold container. The annular coil is supported and fixed on the plurality of brackets. In this way, a stable support can be provided for the annular coil. Even if the compressor generates vibration during operation, the relative position of the annular coil and the cold container can be ensured to remain unchanged, thereby reducing noise. Moreover, under the support of the plurality of brackets, the annular coil can be spaced apart from the bottom wall of the cold container to avoid direct contact between the annular coil and the bottom wall of the cold container and resulting in loss of cooling capacity. In addition, the gaps between the plurality of brackets also allow water to flow freely within and outside the area surrounded by the annular coil, so that the water temperature in the cold container is uniform, and when the water level in the cold container is low, the brackets will not confine the water to the area surrounded by the annular coil.

[0014] Exemplarily, the plurality of brackets include: a plurality of limit members and a support member. The plurality of limit members are arranged at intervals around the vertical axis, and the annular coil is sleeved on the plurality of limit members. The plurality of limit members limit the annular coil in the horizontal direction. The annular coil is supported on the support member so that the annular coil is spaced apart from the bottom surface of the cold container. The plurality of limit members are arranged at intervals around the vertical axis. The annular coil is sleeved on the plurality of limit members so that the plurality of limit members limit the annular coil in the horizontal direction. The annular coil is supported on the support member so that the annular coil is spaced apart from the bottom surface of the cold container, thereby avoiding direct contact between the annular coil and the bottom wall of the cold container and causing loss of cooling capacity. This bracket has the advantages of simple structure and convenient processing.

[0015] Exemplarily, the support member and the plurality of stoppers are separately arranged. In this case, the support member and the plurality of stoppers are independent of each other. There can be a plurality of support members, which can form a uniform support for the annular coil. The support member and the plurality of stoppers are separately arranged, which has a lower requirement for processing accuracy and is more convenient to assemble.

[0016] Exemplarily, each of the plurality of limit members is connected to a support member. Each limit member may be connected to one or more support members. In this way, the limit member can be reliably fixed on the bottom surface of the cold cabinet. This form of bracket structure is more compact.

[0017] For example, the water purifier is a desktop water purifier. Among the many types of water purifiers, desktop water purifiers have the highest requirements for space utilization. The adoption of this solution can significantly reduce the volume occupied by it, which is very important for household water purifiers, especially desktop water purifiers.

[0018] 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.

[0036] 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.

[0037] 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.

[0038] The embodiments of the utility model provide a new design of a water purifier, which is typically used in household water purifiers, but the present application does not exclude the possibility of applying it to commercial water purifiers. The water purifier can be any of a built-in water purifier embedded in a cabinet, a desktop water purifier placed on a countertop, and an under-the-counter water purifier placed under a cabinet. Regardless of the trend of intelligentization or miniaturization of water purifiers, it is expected that the structure of the water purifier will be more compact and the space utilization will be more reasonable, provided that other performances of the water purifier are not damaged. Among the various types of water purifiers mentioned above, the desktop water purifier has the highest requirement for space utilization, because the desktop water purifier usually includes a water tank. Figure 1 and Figure 2 FIG. 2 shows a tabletop water purifier according to an exemplary embodiment of the present application. Figure 1 and Figure 2 As shown, the table-top water purifier may include a main body 1 and a water tank 2 .

[0039] Most of the components of the desktop water purifier are contained in the main body 1, including the cold tank 10, the refrigeration cycle system 20, the filter element 30, etc., which will be mentioned later. The water tank 2 is detachably connected to the main body 1. The water tank 2 can be used to store raw water. The user can remove the water tank 2 and only carry the water tank 2 to a water source such as tap water for filling, without having to carry the entire water purifier. The water tank 2 can be installed to the main body 1 in the lateral direction, and the size of the water tank 2 in the lateral direction may not be greater than half of the size of the desktop water purifier in the lateral direction. The desktop water purifier 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 2 in the lateral direction allows it to be taken out through a smaller gap.

[0040] The filter element 30 may include a reverse osmosis filter element. The pore size of the reverse osmosis filter element is 0.1 micron, which is 10 times larger 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 2 to mix with the raw water, or a partition is provided in the water tank 2 to separate the raw water and the concentrated water. Of course, a separate water tank can also be provided to store concentrated water.

[0041] Normally, the water tank 2 can have a volume of about 5L, so as to meet the daily water demand without frequent water addition. The water tank 2 is basically the largest single component in the desktop water purifier. Therefore, in the desktop water purifier, higher requirements are put forward for the rational use of space. The principle of the present application will be explained below by taking the desktop water purifier as an example.

[0042] See also Figures 3 to 5 As shown, the water purifier may further include a cold tank 10 and a refrigeration cycle system 20. The refrigeration cycle system 20 may include a compressor 201, a condenser 202, and an evaporator 203. The outlet of the evaporator 203 is connected to the inlet of the compressor 201 through a first pipeline 204, the outlet of the compressor 201 is connected to the inlet of the condenser 202, and the outlet of the condenser 202 is connected to the inlet of the evaporator 203 through a second pipeline 205. The evaporator 203 is arranged in the cold tank 10 and is located at the lower part of the cold tank 10, for cooling the water in the cold tank 10. The compressor 201 and the condenser 202 are arranged outside the cold tank 10. Among them, the outlet of the compressor 201 and the inlet of the condenser 202 may be connected through a pipeline or directly.

[0043] In the water purifier provided by the embodiment of the utility model, since the evaporator 203 is arranged in the cold tank 10, the refrigeration efficiency can be improved. Moreover, the evaporator 203 used in the water purifier is usually in the shape of a coil. When it is placed inside the cold tank 10, cold water can completely fill the space around the evaporator 203, which can significantly reduce the volume occupied by the evaporator 203 compared to being arranged outside the cold tank 10. This is very important for household water purifiers, especially desktop water purifiers. In addition, the evaporator 203 in the present application is located at the lower part of the cold tank 10, and the refrigeration can be maintained only by ensuring that the lower part of the cold tank 10 is submerged in water, and the requirements for the water level in the cold tank 10 are relatively low. In the case of a small amount of water, water can be added to the cold tank 10 when the water level in the cold tank 10 is lower than the lower limit of the liquid level, so that the compressor 201 can be avoided from starting and stopping frequently. For some types of water purifiers, it may also include other functional modules such as ice making modules. Therefore, a water purifier in which the upper space of the cold container 10 is used to place such functional modules, and a water purifier in which the upper limit of the liquid level is located at the top of the cold container 10 so that it can be completely used to store cold water, can both use this type of cold container 10, so the cold container 10 is more compatible.

[0044] For example, Figure 4 As shown, the top of the cold container 10 may have an opening 101, and the first pipeline 204 and the second pipeline 205 are connected between the evaporator 203 in the cold container 10 and the compressor 201 and the condenser 202 outside the cold container 10 through the opening 101. Exemplarily, an openable and closable upper cover 102 may be provided at the opening 101 of the cold container 10. The evaporator 203 may be installed inside the cold container 10 through the opening 101, and the inside of the cold container 10 may be cleaned through the opening 101 on a daily basis. The first pipeline 204 and the second pipeline 205 are extended into the cold container 10 by using the opening 101, and sealing treatment is not required, thereby reducing the cost of the water purifier.

[0045] Of course, in other embodiments not shown, the first pipeline 204 and the second pipeline 205 may also pass through the side wall and the bottom wall of the cold container 10 and extend into the cold container 10. In this case, through holes may need to be provided on the side wall and the bottom wall of the cold container 10, so it is necessary to ensure the sealing of the through holes after installation. Optionally, for the aforementioned embodiment of placing other functional modules in the upper part of the cold container 10, the first pipeline 204 and the second pipeline 205 may also be passed through the upper part of the side wall of the cold container 10 into the cold container 10. If the waterproof requirement is not high here, it may be considered to reduce the sealing level or not to set the sealing.

[0046] Taking into account that only providing cold water may still not satisfy the preferences and needs of some users for cold drinks, on this basis, the beverage purifier provided in the embodiment of the utility model can also have an ice-making function.

[0047] For example, Figure 6 As shown, in some embodiments, the refrigeration cycle system 20 of the water purifier may further include an ice-making head 206. Exemplarily, the ice-making head 206 may have a refrigerant channel, which may be connected to the compressor 201 through an external refrigerant circulation pipeline. Fig. 9 The inlet 2603 of the refrigerant channel in the ice-making head 206 is connected to the outlet of the condenser 202. The outlet 2604 of the refrigerant channel is connected to the inlet of the compressor 201. The ice-making head 206 can be located in the cold container 10 and at the upper part of the cold container 10. The ice-making head 206 is used to make ice cubes thereon.

[0048] The ice-making head 206 can be considered as an evaporator. Exemplarily, the ice-making head 206 may include a main pipe 2601 and a plurality of ice-hanging ends 2602 arranged on the main pipe 2601. The plurality of ice-hanging ends 2602 extend downward from the main pipe 2601 respectively. The plurality of ice-hanging ends 2602 are spaced apart from each other. The refrigerant channel is mainly located in the main pipe 2601, and the plurality of ice-hanging ends 2602 can be heat-exchanged with the main pipe 2601. Optionally, the refrigerant channel can also extend from the main pipe 2601 into the plurality of ice-hanging ends 2602. When the ice-making head 206 is working, ice cubes 800 can be formed on the plurality of ice-hanging ends 2602 respectively, and the size of the ice cubes 800 on the plurality of ice-hanging ends 2602 can be controlled by controlling the working time of the compressor 201. If necessary, the ice cubes on the adjacent ice-hanging ends 2602 can be prevented from contacting each other, so that a small ice cube is formed on each ice-hanging end 2602. Of course, if necessary, the ice cubes on the plurality of ice hanging ends 2602 can be connected into a whole block. The compressor 201 has a lower refrigeration temperature and a higher efficiency, can quickly realize ice making, and has a lower energy consumption.

[0049] The ice-making head 206 and the evaporator 203 are connected in parallel. In order to make them operate independently, for example, the evaporator 203 may be connected in series with a first control valve 210, and the ice-making head 206 may be connected in series with a second control valve 220.

[0050] In the above embodiment, the lower part of the cold container 10 can be used to store cold water, the evaporator 203 is used to refrigerate the water stored in the cold container 10, and the ice-making head 206 on the upper part of the cold container 10 can be used to make ice. Therefore, the compressor 201 and the condenser 202 of the refrigeration cycle system 20 can be used to add an ice-making function to the water purifier, so that the needs of users can be better met without increasing the size of the water purifier too much.

[0051] Further, see Figures 6 to 8, an ice delivery channel 40 may also be provided in the cold chamber 10. The ice delivery channel 40 is located directly below the ice making head 206 and is used to receive ice cubes. The ice delivery channel 40 is located directly below the ice making head 206, so that the ice cubes formed on the ice making head 206 can fall directly on the ice delivery channel 40 under the action of gravity. In order to achieve this purpose, the orthographic projection of the ice cubes on the ice making head 206 on the horizontal plane must fall into the orthographic projection of the ice delivery channel 40 on the horizontal plane, so that the ice delivery channel 40 can receive ice cubes. The beverage purifier may have an ice outlet 50, and the ice delivery channel 40 extends downwardly to the ice outlet 50. After the ice cubes made by the beverage purifier through the ice making head 206 fall to the ice delivery channel 40, they slide from the inclined ice delivery channel 40 to the ice outlet 50 for users to take. Optionally, the ice outlet 50 may be connected to the ice storage box 3. Exemplarily, the ice outlet 50 can be arranged above the ice storage box 3, and the top of the ice storage box 3 is provided with an ice inlet. The ice inlet can be directly opposite to the ice outlet 50, and the gap between the edge of the ice inlet and the edge of the ice outlet 50 in the vertical direction is small to prevent the ice cubes from getting stuck in the gap between the two. Exemplarily, a drain port (not shown) can be provided at the bottom of the ice storage box 3, and the water entering the ice storage box 3 with the ice cubes and the water generated by the melting of the ice cubes can be discharged to the sewer or other wastewater collection container through the drain port of the ice storage box 3. In this way, water accumulation in the ice storage box 3 can be avoided, and the ice cubes can be dried at the same time. Compared with ice cubes soaked in water or wet ice cubes, dry ice cubes are not easy to adhere, are less likely to breed bacteria, can be stored for a longer time, and have a relatively good taste. In order to extend the storage time of ice cubes, the ice storage box 3 can use insulation materials, or be coated or lined with insulation materials, so as to reduce the heat exchange between the ice cubes and the outside world. In some exemplary embodiments, the ice storage box 3 may not be provided with a drain port, and the ice cubes in the ice storage box 3 may be separated from the bottom surface of the ice storage box 3 so as to drain the ice cubes.

[0052] like Fig. 9 As shown, the ice conveying channel 40 is provided with a drain hole 401, and the drain hole 401 is connected to the lower part of the cold container 10. Water is required in the process of making ice cubes by the ice-making head 206, and since the ice-making power of the beverage purifier is limited, it is impossible to condense all the water used for ice making into ice cubes. In some embodiments, water can be poured onto the ice-making head 206 to generate ice cubes on the ice-making head 206. In the embodiment using the above-mentioned water sprinkling scheme, most of the water will flow along the ice-making head 206 to the ice conveying channel 40. This part of the water can flow back into the cold container 10 through the drain hole 401. In other embodiments, such as Figure 6 and 8As shown, an ice-making water storage box 207 may also be included. The ice-making water storage box 207 may be arranged between the ice-making head 206 and the ice delivery channel 40. The top of the ice-making water storage box 207 has an opening, and the ice-making water storage box 207 has a working position. When the ice-making water storage box 207 is in the working position, the ice-making head 206 extends into the ice-making water storage box 207 through the opening. Water can be contained in the ice-making water storage box 207, and the ice-making head 206 extends below the water surface, so that ice cubes are formed in the part immersed in the water surface. The length and width of the ice cubes thus made are relatively appropriate, and the noise of running water will not be generated all the time, and the user experience is better. Exemplarily, the ice-making water storage box 207 may also have an ice-falling position, and when the ice-making water storage box 207 is in the ice-falling position, it is located outside the falling path of the ice cube 800. The ice-making device may also include a driver 208, and the ice-making water storage box 207 is movable between the working position and the ice-falling position under the action of the driver 208.

[0053] By providing the inclined ice conveying channel 40, the ice cubes can automatically slide down to the ice storage box 3 under the action of their own gravity, thereby making the structure inside the cold container 10 relatively simple and reducing the occupied space. In addition, in the process of ice cubes and some residual cold water sliding down the ice conveying channel 40 toward the ice outlet 50, the cold water can return to the cold container 10 through the drain hole 401, thereby reducing the waste of cold water. At the same time, relatively dry ice cubes can enter the ice storage box 3. Dry ice cubes are not easy to stick together, and are even less likely to breed bacteria. They can be stored for a longer time and have a relatively good taste.

[0054] Optionally, the water purifier may further include a water pump (not shown in the figure), the water inlet of the water pump is connected to the cold tank 10, and the water outlet of the water pump provides water for making ice cubes to the ice-making head 206. Since the ice-making head 206 itself is located inside the cold tank 10, the water stored in the cold tank 10 is directly transported to the ice-making head 206 through the water pump for ice making, which is more convenient than transporting water from other parts of the water purifier such as the pure water tank. At the same time, the cold water stored in the cold tank 10 is pure water with a lower temperature, and the amount of cold required in the process of making ice cubes is less, and the energy consumption of ice making is lower.

[0055] In the embodiment where ice is made by directly spraying water onto the ice-making head 206, the water outlet of the water pump may be connected to a nozzle, through which cold water is sprayed onto the ice-making head 206. In the embodiment where an ice-making water storage box 207 is provided, the water outlet of the water pump may be connected to the ice-making water storage box 207, and the ice-making head 206 may be partially immersed in water, thereby achieving more efficient ice making.

[0056] In order to expand the contact area between the evaporator 203 and the water in the refrigerating container 10 and improve the refrigeration efficiency, the evaporator 203 can be selected to use a serpentine tube, a coiled tube or a capillary tube structure in the refrigerating container 10. Figure 6As shown, the evaporator 203 is an annular coil around the vertical axis. The annular shape may include a circular ring, a polygon, etc. In other embodiments not shown, the annular coil may also be around the horizontal axis. However, this will increase the height of the coil, so when the water level in the cold tank 10 is low, part of the coil may be exposed above the water surface, resulting in reduced refrigeration efficiency. In contrast, arranging the annular coil around the vertical axis can reduce the height to a certain extent. Moreover, a space for placing the sterilization assembly 60 mentioned later can be formed in the area surrounded by the annular coil.

[0057] For example, Figure 8 As shown, the water purifier also includes a sterilization component 60, which is arranged at the bottom of the cold container 10 and is surrounded by an annular coil (i.e., the evaporator 203). In this way, the water in the cold container 10 can be sterilized by controlling the operation of the sterilization component 60 to prevent bacteria from growing in the cold container 10. The sterilization component 60 can be an ultraviolet lamp, an ozone generator, etc. Taking a commonly used ultraviolet lamp as an example, since the upper part of the annular coil arranged around the vertical axis is open, the sterilization component 60 is arranged there to irradiate most of the water upward. The evaporator 203 basically does not block the ultraviolet rays, so the sterilization effect is better.

[0058] Considering that the evaporator 203 is located in the cold container 10, and the evaporator 203 is connected to the refrigeration cycle system 20 through the first pipeline 204 and the second pipeline 205 via the opening 101. In the case where the evaporator 203 is an annular coil, the annular coil can be limited to increase the stability of the structure.

[0059] like Fig.10 and Fig.11 As shown, the bottom of the cold container 10 is provided with a plurality of brackets 70 spaced apart from each other around a vertical axis. The annular coil is supported and fixed on the plurality of brackets 70. In this way, a stable support can be provided for the annular coil. Figure 3 , even if the compressor 201 generates vibration during operation, the relative position of the annular coil and the cold container 10 can be ensured to remain unchanged, thereby reducing noise. Moreover, under the support of the multiple brackets 70, the annular coil can be spaced apart from the bottom wall of the cold container 10, avoiding direct contact between the annular coil and the bottom wall of the cold container 10 and causing cooling loss. In addition, the gaps between the multiple brackets 70 also allow water to flow freely in and outside the area surrounded by the annular coil, making the water temperature in the cold container 10 uniform, and when the water level in the cold container 10 is low, the brackets 70 will not limit the water to the area surrounded by the annular coil.

[0060] Optionally, the water purifier with the bracket 70 in the cold container 10 can also be provided with the sterilization component 60. The multiple brackets 70 are arranged at intervals to reduce the impact on the sterilization component 60.

[0061] Exemplarily, as shown in the figure, the plurality of brackets 70 include a plurality of limiters 701 and a support member 702. The plurality of limiters 701 are arranged at intervals around the vertical axis. The annular coil is sleeved on the plurality of limiters 701, so that the plurality of limiters 701 limit the annular coil in the horizontal direction. In the illustrated embodiment, the annular coil is a rounded rectangle, and the four limiters 701 are respectively arranged at the four corners of the rounded rectangle. The limiters 701 can be in an arc shape that matches the shape of the annular coil. In other embodiments not shown, the limiters 701 can also be arranged at multiple edges of the rounded rectangle, so that the limiters 701 can be in a straight line shape. The annular coil is supported on the support member 702, so that the annular coil is spaced apart from the bottom surface of the cold tank 10. This bracket 70 has the advantages of simple structure and convenient processing.

[0062] like Figure 10 to Figure 11 As shown, the support member 702 can be separately arranged from the plurality of limit members 701. The support member 702 and the plurality of limit members 701 are independent of each other. There can be a plurality of support members 702, which can form a uniform support for the annular coil. In order to firmly fix the limit member 701 on the bottom surface of the cold container 10, optionally, the limit member 701 can also have a positioning portion 704. The extension direction of the positioning portion 704 and the extension direction of the limit member 701 have a certain angle, so that the limit member 701 is firmly fixed on the bottom surface of the cold container 10. The support member 702 and the plurality of limit members 701 are separately arranged, which has lower requirements for processing accuracy and is more convenient to assemble.

[0063] like Figure 12 to Figure 13 As shown, the support member 702 may also be connected to the limit member 701. Exemplarily, each limit member 701 may be connected to one or more support members 702. Specifically, the support member 702 may be L-shaped, the first end of the support member 702 may be connected to the outer peripheral surface of the limit member 701, the second end of the support member 702 is spaced apart from the outer peripheral surface of the limit member 701 to form a slot 703, and the annular coil is fixed in the slot 703. Since there is an angle between the support member 702 and the limit member 701, the limit member 701 can be reliably fixed on the bottom surface of the cold cabinet 10. In this case, the aforementioned positioning portion 704 can be omitted. This form of the bracket 70 structure is more compact.

[0064] Although Figure 12 to Figure 13 In the embodiment shown, the annular coil is circular, but may also have any other suitable shape. Figure 10 to Figure 11 In the illustrated embodiment, the annular coil may also have any suitable shape.
