[0047] A water purifier is a device used to purify tap water or other water sources, removing impurities, harmful substances, and odors to provide safer drinking water. Water purifiers can be used in various settings such as under the sink and in offices.

[0048] In related technologies, tabletop water purifiers include a connected filter assembly and a water tank, with the water tank typically located at the rear of the unit to store water. During use, water from the tank continuously enters the filter assembly for filtration to obtain drinkable purified water. However, placing the water tank at the rear of the unit makes it inconvenient for users to observe the water level and remove or refill it.

[0049] To address the issue of reduced water output efficiency in water purifiers due to decreased water volume in the tank, referring to... Figures 1 to 5 One embodiment of this application provides a benchtop water chiller, including a housing 100, a middle frame assembly 300, a filter element assembly 400, a pressurized water pumping assembly 500, a cooling assembly 600, and a water outlet assembly 700. A drinking water outlet 110 is provided on one side of the housing 100, and a transparent water tank 200 is detachably connected to the side of the housing 100 adjacent to the drinking water outlet 110. The middle frame assembly 300 is disposed within the housing 100 and divides the inner cavity of the housing 100 into a filter element area 120 and a cooling area 130. The filter element area 120 is located on the side of the housing 100 closer to the drinking water outlet 110, and the cooling area 130 is located away from the filter element area 120. On one side of the water outlet 110; the filter element assembly 400 is disposed in the filter element area 120 and connected to the water tank 200. The filter element assembly 400 is used to filter the water source from the transparent water tank 200 to obtain purified water; the booster pump assembly 500 is disposed in the housing 100. The inlet end of the booster pump assembly 500 is connected to the water tank 200, and the outlet end of the booster pump assembly 500 is connected to the filter element assembly 400; the refrigeration assembly 600 is disposed in the refrigeration area 130 and connected to the filter element assembly 400. The refrigeration assembly 600 is used to refrigerate the purified water to obtain cold water; the water outlet assembly 700 is connected to the refrigeration assembly 600 and is used to outlet water.

[0050] The housing 100 includes a bottom shell 150, a top shell 160, a top plate 170, a sealing plate 140, and two peripheral side plates 180. A drinking water outlet 110 is located on the side of the water tank 200 away from the middle frame assembly 300. A raised edge 152 extends upward from the peripheral edge of the bottom shell 150 away from the drinking water outlet 110. The sealing plate 140 has a semi-circular cross-section. The top wall of the sealing plate 140 is connected to the bottom wall of the top shell 160, and the bottom wall of the sealing plate 140 is connected to the top wall of the bottom shell 150 near the drinking water outlet 110. The open end of the sealing plate 140 is connected to the middle frame assembly 300. A sliding platform 142 extends from the outer side wall of the bottom end of the sealing plate 140. The water tank 200 is a transparent water tank with a U-shaped cross-section, and the water tank 200 slides in conjunction with the sliding platform 142.

[0051] The peripheral side plates 180 are arranged around the bottom shell 150 with protruding edges 152. The overall cross-section of the two peripheral side plates 180 after splicing is U-shaped. One end of the top shell 160 is located above the closing plate 140, and the other end of the top shell 160 is located above the middle frame assembly 300. The cross-section of the end of the top shell 160 above the closing plate 140 is semi-circular, and the cross-section of the end of the top shell 160 above the middle frame assembly 300 is U-shaped. The corner of the top shell 160 away from the drinking water outlet 110 is chamfered. The top plate 170 is placed on top of the top shell 160 to close the opening of the top shell 160.

[0052] The middle frame assembly 300 provides stable support for the filter element assembly 400 and the refrigeration assembly 600, and can divide the internal space of the housing 100 to improve the compactness of the overall structure of the chiller.

[0053] Specifically, in use, the water in the tank 200 is drawn out and pressurized by the pressurized water pumping component 500 and then transported to the filter element component 400. The filter element component 400 filters and purifies the water from the water tank 200 to obtain clean water. The clean water then enters the cooling component 600, where it can be cooled or kept at room temperature. Finally, the water is discharged through the control of the water outlet component 700 so that the user can obtain the clean water they need.

[0054] In this embodiment, the tabletop water chiller features a transparent water tank 200 placed next to the drinking water outlet 110, allowing users to easily observe the water level and replenish it when it is low. The pressurized pumping assembly 500 ensures consistent water pressure even when the water level in the tank is low, guaranteeing the chiller's filtration and output efficiency and enhancing user convenience. Furthermore, the filtered and purified water from the filter assembly 400 is directly drinkable, and can be further purified into cold water through the cooling assembly 600 and the water outlet assembly 700, further improving user convenience. Additionally, the mid-frame assembly 300 optimizes the space allocation within the housing 100, placing the filter assembly 400 in the filter area 120 and the cooling assembly 600 in the cooling area 130. This improves the chiller's compact design, reducing its overall footprint and facilitating easy transport and relocation.

[0055] Reference Figure 2 and Figure 3 In some embodiments, the middle frame assembly 300 includes a first support portion 310, a second support portion 320, and a receiving portion 330. The second support portion 320 is disposed above the first support portion 310 and encloses a receiving area 340, in which the cooling area 130 is located. The receiving portion 330 is disposed on the side of the second support portion 320 near the drinking water outlet 110 and is located within the filter element area 120. The side of the first support portion 310 facing the inner bottom wall of the housing 100 and encloses the inner side wall of the bottom of the housing 100 to form a holding area 350, in which the pressurized water pumping assembly 500 is located.

[0056] The second support portion 320 includes a base plate 322, an end plate 324, and two side plates 326. The base plate 322 is horizontally positioned, and the end plate 324 is located at one end of the base plate 322 near the filter element assembly 400. The bottom of the end plate 324 extends towards the inner bottom of the housing 100. The bottom of the end plate 324, the bottom surface of the base plate 322, the inner surface of the sealing plate 140, and the inner surface of the bottom shell 150 enclose a holding area 350. The side wall of the side plate 326 near the drinking water outlet 110 is connected to the end plate 324. The side plate 326, the end plate 324, and the upper surface of the base plate 322 enclose a holding area 350, which is located below the receiving area 340. The filter element area 120 is located on the side of the receiving area 340 near the drinking water outlet 110, and the cooling area 130 is located within the receiving area 340 and close to the filter element area 120. In addition, a reinforcing rib 3262 is integrally formed on the outer side wall of the side panel 326 along the vertical direction to enhance the support strength of the middle frame assembly 300.

[0057] The first support portion 310 includes four support columns 3222, which are vertically connected to the four corners of the bottom wall of the base plate 322, and the bottom walls of the support columns 3222 are fixed to the housing 100 by screws. The receiving portion 330 includes a horizontal plate 332 and a vertical plate 334. The longitudinal section of the receiving portion 330 is L-shaped. The vertical plate 334 is connected to the side wall of the end plate 324 near the filter element assembly 400, and the cross-section of the vertical plate 334 is M-shaped. The horizontal plate 332 is integrally formed on the side wall at the bottom end of the vertical plate 334, and the cross-section of the horizontal plate 332 is semi-circular. In this embodiment, the first support portion 310, the second support portion 320, and the receiving portion 330 can be integrally formed.

[0058] In this embodiment, the inner cavity of the housing 100 is divided into a filter element area 120 for accommodating the filter element assembly 400, a accommodating area 340 for accommodating the refrigeration assembly 600, and a holding area 350 for accommodating the water pipes by means of the cooperation of the first support part 310, the second support part 320 and the receiving part 330, thereby achieving a reasonable allocation of the internal space of the housing 100, which helps to improve the compactness of the overall structure of the chiller.

[0059] Reference Figure 2 and Figure 3 In some embodiments, the sealing plate 140 is disposed on the side of the middle frame assembly 300 near the drinking water outlet 110. The sealing plate 140 is disposed around the filter element assembly 400. The side of the sealing plate 140 away from the middle frame assembly 300 forms a holding groove 141. The transparent water tank 200 is fitted into the holding groove 141. The side of the transparent water tank 200 that is fitted into the holding groove 141 is provided with a receiving groove. The receiving groove matches the side of the sealing plate 140 that protrudes from the filter element assembly 400.

[0060] The sealing plate 140 is fixedly connected to the end plate 324 on the side near the filter element assembly 400, and the side wall of the sealing plate 140 away from the filter element assembly 400 and the top wall of the slide table 142 form a holding groove 141.

[0061] Specifically, when the water level in the transparent water tank 200 is low, the user can slide the transparent water tank 200 out along the side away from the middle frame assembly 300 to fill it with water; after the transparent water tank 200 is full of water, the user can slide the transparent water tank 200 towards the middle frame assembly 300 until it is fully engaged with the holding slot 141. In other words, the engagement of the transparent water tank 200 with the holding slot 141 makes it easy for the user to take out and put in the transparent water tank 200.

[0062] Reference Figures 2 to 4In some embodiments, the filter assembly 400 includes a mounting bracket 410 and a filter module 420, wherein the mounting bracket 410 is disposed on a horizontal plate 332; and the filter module 420 is disposed on the mounting bracket 410 by means of a mounting member.

[0063] Specifically, the height of the lower surface of the horizontal plate 332 is not lower than the height of the upper surface of the base plate 322. Two limiting grooves are provided on the top wall of the horizontal plate 332 along the horizontal direction, and the end of the limiting groove away from the refrigeration component 500 passes through the side wall of the horizontal plate 332. The mounting bracket 410 is sleeved with the filter module 420. Four limiting posts are connected to the four corners of the bottom wall of the mounting bracket 410. Two limiting posts located on the same side of the length direction of the limiting groove are slidably connected to one of the limiting grooves, and the other two limiting posts are slidably connected to the other limiting groove. The limiting posts are fixed to the horizontal part by screws.

[0064] The bottom of the filter module 420 is also provided with a water inlet 422 and a water outlet 424. The water inlet 422 is connected to the booster pumping assembly 500 for water intake; the water outlet 424 is connected to the water outlet pipe 430 through the purified water outlet pipe 426 for transporting the purified water filtered by the filter module 420 to the cooling assembly 500 for cooling. The filter area 120 is formed by the enclosure plate 140 and the receiving part 230.

[0065] In this embodiment, the cooperation of the sealing plate 140, the receiving part 230 and the mounting bracket 410 facilitates the installation of the filter module 420 and helps to ensure the compactness of the overall structure.

[0066] Reference Figures 2 to 6 In some embodiments, the booster pumping assembly 500 includes a self-priming booster pump 510 and a pumping pipe 520. The outlet end of the self-priming booster pump 510 is connected to the filter element assembly 400. The inlet end of the pumping pipe 520 is connected to the lower part of the transparent water tank 200, and the outlet end of the pumping pipe 520 is connected to the inlet end of the self-priming booster pump 510.

[0067] The outlet of the self-priming booster pump 510 is connected to the water inlet 422 of the filter module 420 via a water pipe.

[0068] Specifically, during use, the self-priming booster pump 510 draws water from the water tank 200 and delivers it to the filter module 420 through a pipeline. The self-priming booster pump 510 increases the water pressure to ensure that sufficient water pressure is provided even when the water level in the water tank 200 is low, thereby maintaining the normal operation of the filter module 400.

[0069] Reference Figure 5 and Figure 6In some embodiments, the booster pumping assembly 500 further includes a fixing member 530, which is disposed below the filter assembly 400 and located between the lower part of the transparent water tank 200 and the self-priming booster pump 510. The fixing member 530 is used to limit the pumping pipe 520.

[0070] Specifically, by setting the fastener 530, the stability and tightness of the connection between the water pumping pipe 520 and the self-priming booster pump 510 can be ensured when the water pressure is increased by the self-priming booster pump 510.

[0071] Reference Figure 5 and Figure 6 In some embodiments, the fixing member 530 includes a fixing base, on which a water pipe 532 is provided. One end of the water pipe 532 is connected to the lower part of the transparent water tank 200, and the other end of the water pipe 532 is connected to a pumping pipe 520, which is bent.

[0072] Specifically, the mounting base can be fixedly connected to the enclosure plate 140 with screws. The bending of the water pipe 520 helps reduce the horizontal space it occupies, thus helping to ensure the neatness and compactness of various water pipes within the storage area 350.

[0073] Reference Figures 4 to 6 In some embodiments, a pipe outlet 3320 is provided through the receiving part 330, the bottom of the filter element assembly 400 is connected to the outlet end of the self-priming booster pump 510 through the water inlet pipe, and the bottom of the filter element assembly 400 is also connected to the cooling component 600 through the water outlet pipe 430. Both the water inlet pipe and the water outlet pipe 430 are installed in the pipe outlet 3320, and the water outlet ends of both the water inlet pipe and the water outlet pipe 430 are located in the holding area 350.

[0074] One end of the inlet pipe is connected to the outlet end 520 of the self-priming booster pump, and the other end of the inlet pipe is connected to the inlet end of the filter module 420. One end of the outlet pipe 430 is connected to the outlet end of the filter module 420, and the other end of the outlet pipe 430 is connected to the refrigeration component 600. Both the inlet and outlet ends of the filter module 420 are located at the bottom of the filter module 420. After the filter module 420 is installed on the filter module 420 mounting base 410, both the inlet and outlet ends of the filter module 420 are opposite to the pipeline outlet 3320.

[0075] Specifically, the pipe outlet 3320 is installed through the horizontal plate 332 so that the inlet and outlet pipes 430 at the bottom of the filter module 420 can pass through the pipe outlet 3320. Positioning the end of the inlet and outlet pipes 430 away from the filter module 420 within the storage area 350 allows for organized storage of the water pipes, reducing the space occupied by the water pipes and thus contributing to the compactness of the overall structure of the chiller.

[0076] In this embodiment, a pipe outlet 3320 is provided through the horizontal plate 332, which facilitates the installation of the inlet and outlet pipes 430 and also helps to reduce the space occupied by the inlet and outlet pipes 430, thereby improving the overall compactness of the chiller.

[0077] Reference Figures 2 to 5 In some embodiments, the refrigeration assembly 600 includes a cooling tank 610 and a cooling water pipe. The cooling tank 610 is located within the refrigeration zone 130. The cooling tank 610 includes a connected cooling inlet 614 and a cooling outlet 612. The cooling outlet 612 is connected to the water outlet assembly 700, and both the cooling inlet 614 and the cooling outlet 612 are located above the refrigeration zone 130. The inlet end of the cooling water pipe is connected to the water outlet pipe 430, and the outlet end of the cooling water pipe is connected to the cooling inlet 614.

[0078] Since there is a certain space between the upper surface of the cooling tank 610 and the top plate 170, the refrigeration inlet 614 and the refrigeration outlet 612 are both opened on the top wall of the cooling tank 610. That is, the refrigeration inlet 614 and the refrigeration outlet 612 are both located above the refrigeration zone 130, which helps to accommodate the water pipes connected to the refrigeration inlet 614 and the refrigeration outlet 612, thereby ensuring the compactness of the chiller structure.

[0079] Specifically, the purified water filtered by the filter module 420 enters the cooling inlet 614 of the cooling tank 610 through the water outlet pipe 430, and after being cooled by the cooling tank 610, it flows from the cooling outlet 612 to the water outlet assembly 700 for the user to drink.

[0080] Reference Figure 2 and Figure 3 In some embodiments, the benchtop chiller also includes a normal temperature water pipe, the inlet end of which is connected to the outlet pipe 430, and the outlet end of which is connected to the outlet assembly 700. The inlet ends of both the chilled water pipe and the normal temperature water pipe are located within the holding area 350.

[0081] Specifically, the water outlet pipe 430 has two outlet ends, one connected to the chilled water pipe and the other connected to the ambient temperature water pipe. Placing both the inlet ends of the chilled water pipe and the ambient temperature water pipe within the holding area 350 helps ensure the overall structure's regularity and compactness.

[0082] In this embodiment, by setting two outlet ends on the water outlet pipe 430, the water flow is divided into two paths to enter the cooling component 600. Under the control of the water outlet component 700, cold water and room temperature water can be discharged separately, thereby better meeting the user's water needs.

[0083] Reference Figure 2 and Figure 3 In some embodiments, the second support 320 is provided with two through grooves 3260 in the vertical direction on the side walls on both sides of the cold tank 610. One through groove 3260 is used to accommodate the pipe for chilled water, and the other through groove 3260 is used to accommodate the pipe for room temperature water.

[0084] Specifically, the through groove 3260 serves to limit and guide the chilled water pipes and the ambient temperature water pipes. In addition, by opening the through groove 3260 on the side wall of the side plate 326, the internal space of the housing 100 occupied by the chilled water pipes and the ambient temperature water pipes can be reduced, thereby helping to further improve the structural compactness of the chiller.

[0085] Reference Figures 5 to 8 In some embodiments, the benchtop chiller also includes a solenoid valve flow meter module 800 disposed in the holding area 350. Both the chilled water pipe and the ambient temperature water pipe are connected to the solenoid valve flow meter module 800. The solenoid valve flow meter module 800 is used to monitor the inlet flow rate of the chilled water pipe and the inlet flow rate of the ambient temperature water pipe.

[0086] The water outlet pipe 430 includes a first water outlet pipe 431 and a second water outlet pipe 432. The first water outlet pipe 431 is connected to the water source outlet 424 at the bottom of the filter module 420. The solenoid valve flow meter module 800 includes a support frame 810, a flow monitoring element 820, and a solenoid valve 830. The support frame 810 is located within the holding area 350 and is connected to the second support part 220. The flow monitoring element 820 is mounted on the support frame 810. The inlet end of the flow monitoring element 820 is connected to the first outlet pipe 431, and the outlet end of the flow monitoring element 820 is connected to the inlet end of the second outlet pipe 432. The flow monitoring element 820 is used to monitor the inlet flow rate of the chilled water pipe and the inlet flow rate of the ambient temperature water pipe. The solenoid valve 830 has one inlet and two outlets. The inlet of the solenoid valve 830 is connected to the outlet end of the second outlet pipe 432, one outlet of the solenoid valve 830 is connected to the chilled water pipe, and the other outlet of the solenoid valve 830 is connected to the ambient temperature water pipe.

[0087] In addition, the solenoid valve flow meter module 800 also includes a connecting plate 840, which is fixedly connected to the support frame 810 on the side near the filter module 420. The drain pipe 618 is fixed to the support frame 810 through the connecting plate 840, which helps to ensure stability during drainage.

[0088] Specifically, when the user controls the solenoid valve 830 connected to the ambient temperature water pipe to close and the solenoid valve 830 connected to the chilled water pipe to open via the water outlet component 700, the benchtop chiller can supply chilled water; when the user controls the solenoid valve 830 connected to the ambient temperature water pipe to open and the solenoid valve 830 connected to the chilled water pipe to close via the water outlet component 700, the benchtop chiller can supply ambient temperature water. The flow monitoring component 820 can monitor the inlet flow rates of both the chilled water pipe and the ambient temperature water pipe in real time to avoid excessive or insufficient water pressure. The flow rate can also be adjusted according to usage needs to ensure a moderate water volume during filtration, preventing incomplete filtration due to excessively fast flow or inefficient filtration due to excessively slow flow, thus ensuring user convenience when drinking water. Furthermore, to improve the installation efficiency of the chiller, the solenoid valve flow meter module 800 in this embodiment can be pre-integrated as a complete functional module and then fixed inside the housing 100 with screws.

[0089] Reference Figures 1 to 3In some embodiments, the water outlet assembly includes a tee connector 710, an outlet pipe, and a control component 720. The first interface end of the tee connector 710 is connected to the outlet end of the refrigeration assembly 600, and the second interface end of the tee connector 710 is connected to the outlet end of the ambient temperature water pipe. The inlet end of the outlet pipe is connected to the third interface end of the tee connector 710, and the outlet end of the outlet pipe is connected to the drinking water outlet 110. The control component 720 is disposed on the housing 100 and is connected to the solenoid valve flow meter module 800. The control component 720 is used to control the solenoid valve flow meter module 800 to perform on / off operations on the refrigeration water pipe and the ambient temperature water pipe.

[0090] The three-way connector 710 is located above the cooling zone 130 to fully utilize the space above the housing 100 in the cooling zone 130. The water outlet assembly 700 also includes a bend connector 730, a water outlet base 740, and a water receiving platform 750. The water outlet pipe connects to the drinking water outlet 110 via the bend connector 730. The water outlet base 740 is connected to the top housing 160 and has a flow channel within it, through which the water outlet pipe connects. The water receiving platform 750 is connected to the outer wall of the bottom of the sealing plate 140. The water receiving platform 750 has a water receiving trough within it, and a perforated water receiving plate above the trough to hold water cups and other water-receiving tools. The trough can collect excess water that falls into the water.

[0091] Specifically, the control unit 720 includes control buttons, including a cold water button and a room temperature water button, which are electrically connected to the tee connector 710. When the user presses the cold water button, the first inlet end of the tee connector 710 is connected, and at this time, only cold water flows out from the outlet pipe; when the user presses the room temperature water button, the second inlet end of the tee connector 710 is connected, and at this time, only room temperature water flows out from the outlet pipe.

[0092] In this embodiment, the combination of the three-way connector 710, the water outlet pipe and the control component 730 facilitates the output of cold water or room temperature water according to user needs, thereby ensuring a good user experience for the chiller.

[0093] Reference Figure 4 and Figure 5 In some embodiments, a drain hole 1500 is provided through the bottom wall of the housing 100. The benchtop chiller also includes a drain pipe 618. One end of the drain pipe 618 is connected to the condensate drain outlet 619 of the cooling tank 610, and the other end of the drain pipe 618 is connected to the drain hole 1500. A sealing member 450 for opening and closing the drain hole 1500 is provided on the bottom wall of the housing 100.

[0094] The drain hole 1500 is provided through the bottom shell 150. Since the cold water produced by the refrigeration component 600 may not be consumed in time, and the cold water may deteriorate when stored in the refrigeration component 600 for a long time, affecting the user's health, it is necessary to release the unused cold water periodically.

[0095] Specifically, the sealing component 450 includes a flexible sealing plug, which can be made of medical-grade silicone. During the use of this water chiller, the flexible sealing plug is used to seal the drain hole 1500. After the water chiller has been used for a period of time, the user can move the entire unit to the water tank, remove the flexible sealing plug, and drain the cold water that has not been consumed for a long time from the refrigeration unit 600.

[0096] In this embodiment, the combination of drain pipe 618 and sealing component 450 allows users to promptly drain the prepared cold water from the water chiller if it has not been consumed for a long time, thus ensuring the health and safety of the cold water consumed by the user.

[0097] Reference Figures 3 to 6 In some embodiments, the chiller also includes a heat dissipation component 900, which is disposed on the side of the middle frame component 300 away from the drinking water outlet 110, and is disposed opposite to the cooling component 600.

[0098] The heat dissipation assembly 900 includes a bracket 910 and a cooling fan 920. The cooling fan 920 is fixed by the bracket 910 and is positioned opposite to the cooling tank 610. Several air ducts 182 are provided through the side wall of the peripheral side plate 180 opposite to the cooling fan 920. An air inlet 154 is provided through the bottom wall of the bottom shell 150 away from the drinking water outlet 110.

[0099] Specifically, a heat sink 616 is provided on the side wall of the cooling tank 610 near the cooling fan 920. The heat sink 616 includes several heat sinks arranged in a horizontal array and vertically connected to the side wall of the cooling tank 610. The bracket 910 can be fixed between the heat sinks at the outermost edges on both sides with screws. In addition to the cooling zone 130, the holding area 350 also includes a heat dissipation zone 352. The heat dissipation zone 352 is located on the side of the cooling zone 130 away from the drinking water outlet 110. The cooling fan 920 is located in the heat dissipation zone 352. An air inlet notch 3220 is provided through the end of the base plate 322 away from the end plate 324.

[0100] Since the refrigeration component 600 generates a certain amount of heat when it is working, in order to ensure the normal operation of the chiller, the cooling fan 920 draws the cold air from the bottom of the chiller into the housing 100 through the air inlet 154 into the refrigeration zone 130. With the cooperation of the heat dissipation component 616, the heat generated by the cooling tank 610 is discharged through the air duct baffle 182, thereby achieving heat dissipation of the cooling tank 610 and helping to ensure the normal operation of the chiller.

[0101] Reference Figure 2 and Figure 3 In some embodiments, the chiller also includes a power module 1000, and the filter assembly 400, cooling assembly 600, water outlet assembly 700, and heat dissipation assembly 900 are all connected to the power module 1000 to ensure the normal operation of the chiller. The power module 1000 is located above the holding area 350, and the power module 1000 is located on the side of the cooling area 130 away from the drinking water outlet 110.

[0102] Specifically, the power module 1000 supplies power to the filter assembly 400, the cooling assembly 600, the water outlet assembly 700, and the heat dissipation assembly 900 to ensure the normal operation of the chiller. Placing the power module 1000 above the holding area 350 and on the side of the cooling area 130 away from the drinking water outlet 110 helps to further improve the compactness of the chiller's structure.

[0103] The tabletop water chiller of this application features a transparent water tank 200 placed next to the drinking water outlet 110, allowing users to easily observe the water level in the tank 200 and conveniently refill it when the level is low. The booster pump assembly 500 ensures consistent water output pressure even when the water level in the tank 200 drops, thus guaranteeing the chiller's filtration and water output efficiency and enhancing user convenience. Furthermore, the water obtained after filtration and purification by the filter element assembly 400 is directly drinkable. The water purifier can also produce drinkable cold or room temperature water through the combination of the cooling component 600, the water outlet component 700, and the room temperature water pipe, thereby further improving the convenience of use for users. In addition, the space inside the housing 100 is reasonably allocated by the middle frame component 300, placing the filter element component 400 in the filter element area 120 and the cooling component 600 in the cooling area 130, which helps to improve the compactness of the chiller structure, thereby reducing the overall space occupied by the chiller and making it easier for users to move or transport it.
