Description

Technical Field

[0001] This application relates to the field of water purification equipment technology, specifically to a countertop water purifier. Background Technology

[0002] With economic development and improved living standards, consumers are paying increasing attention to healthy drinking water and have higher requirements for its use. Water purifiers are water treatment devices that can deeply filter and purify water according to usage requirements. Especially compact countertop water purifiers can be placed directly on a countertop, taking up little space and being convenient to use. To meet diverse user needs, existing countertop water purifiers integrate multiple functions, such as water purification, heating, and cooling. Countertop water purifiers with cooling functions, in particular, can provide users with cold water and even ice, gaining increasing recognition and favor among consumers.

[0003] Currently, common countertop water purifiers with cooling functions can be divided into compressor cooling and electronic cooling. Compressor cooling has a complex structure, high cost, and a wide range of applications. Electronic cooling, which uses cooling coils, is becoming increasingly popular. However, electronic cooling has high requirements for the external environment and needs to be able to exhaust and dissipate heat from the cooling coils in a timely manner. If the machine body cannot be reasonably designed with an exhaust and heat dissipation structure, the cooling efficiency will be greatly reduced.

[0004] Currently, heat dissipation is mainly achieved through cooling fans and heat dissipation plates, with air outlet channels set on the equipment casing. The heat dissipation plate is connected to several heat dissipation fins, and the heat dissipation surface of the cooling fins rests against the plate. The cooling fan draws in cool air from the outside and blows it onto the heat dissipation fins, then exits through the air outlet channels to carry away heat. However, the airflow tends to diffuse disorderly within the machine, creating turbulence. This not only increases air noise but also slows down the speed at which heat is carried away, resulting in poor heat dissipation. Furthermore, the ventilation area of ​​the air outlet channel is a crucial factor affecting heat dissipation efficiency. A larger channel area is more beneficial for heat dissipation but also has drawbacks. For example, it exposes a large portion of the internal structure of the casing to the outside view, affecting the overall aesthetics of the equipment. Utility Model Content

[0005] This application provides a countertop water purifier to improve or solve, to a certain extent, the technical problems of poor heat dissipation of the cooling element due to disordered diffusion of heat dissipation airflow within the machine body, and the technical problems of the internal structure of the casing being exposed to the external view through the air outlet channel, thus affecting the overall aesthetics of the device.

[0006] The technical solution adopted in this application is as follows:

[0007] A countertop water purifier includes a base and a housing mounted on the base. The housing contains a refrigeration system, which includes an ice chamber, a cooling plate mounted on the ice chamber, and a heat dissipation component for cooling the cooling plate. The housing includes an air inlet area and an air outlet area. A cooling fan is provided between the air inlet area and the heat dissipation component. The air inlet area has an air inlet channel, and the air outlet area has an air outlet channel and a shield. The air outlet channel is inclined towards the air inlet area. The heat dissipation component has a guide slope that guides the airflow from the cooling fan towards the heat dissipation component towards the air outlet channel. The shield is inclined relative to the air outlet channel to block the internal view of the housing.

[0008] In this technical solution, the separate design of the air inlet and outlet zones forms an independent air duct. The outlet duct is designed to slope towards the air inlet zone, which, together with the guide slope of the air-guiding heat dissipation component, forms a directional airflow cooling path. This optimizes the airflow direction, preventing disordered diffusion of airflow within the housing and preventing airflow from returning towards the cooling fan. Airflow does not disturb each other as it passes through the air-guiding heat dissipation component. The airflow is concentrated and flows through the high-temperature area of ​​the component, quickly carrying heat out of the housing through the outlet duct, achieving a better cooling effect. Simultaneously, the synergistic effect of the sloped outlet duct and the guide slope reduces the probability of airflow collision with the housing wall, reducing wind noise caused by turbulence. Furthermore, the obstruction of the housing's internal view prevents users from seeing the interior from the outside, making internal components invisible and significantly improving the overall integrity and aesthetics of the machine.

[0009] The air outlet area is provided with multiple air guide ribs arranged side by side, and the air outlet channel is formed between two adjacent air guide ribs. The air guide ribs are at least partially inclined towards the air inlet area, and the shielding part is formed on the air guide ribs.

[0010] In this technical solution, multiple parallel, inclined air guide ribs form an array-like air outlet channel, achieving uniform airflow distribution and accelerated exhaust. The spacing between adjacent air guide ribs creates a pressure-dividing effect, causing laminar flow within the multiple parallel channels. This helps increase the heat dissipation area of ​​the air duct and also contributes to a more uniform airflow distribution, preventing localized overheating. Furthermore, the at least partially inclined arrangement of the air guide ribs, in addition to forming an air outlet channel tilted towards the air inlet area, also facilitates the formation of a shielding structure, allowing for better visibility of the interior of the casing.

[0011] The air guide rib extends vertically, and the projection of the air guide rib on the horizontal plane is a Z-shaped structure formed by the sequential connection of the inner extension section, the outer extension section and the connecting section. The inner extension section is located inside the housing, the outer extension section is located outside the housing, and the connecting section is inclined towards the air inlet area. Adjacent connecting sections cooperate to form the air outlet channel, and the inner extension section and the outer extension section form the shielding part.

[0012] This technical solution provides a Z-shaped air guide rib. The Z-shaped air guide rib forms a continuous zigzag structure on the horizontal projection plane, serving both airflow guidance and visual obstruction functions. The vortices generated at the bends of the air guide rib can disperse large-scale airflow clusters and reduce high-frequency noise. At the same time, the continuous ridges of the Z-shaped structure not only allow the connecting sections to form an air outlet channel, but also utilize the inclined inner and outer extension sections relative to the connecting sections to form an optical obstruction surface in the frontal view, making the internal components of the housing invisible, significantly improving the appearance integrity. In addition, the Z-shaped rib has higher strength than the straight rib structure, and the air guide rib's resistance to deformation is significantly improved.

[0013] The air guide rib extends vertically, and the projection of the air guide rib on the horizontal plane includes a first inclined segment and a second inclined segment connected at an angle. The first inclined segment is inclined toward the air inlet area, and adjacent first inclined segments cooperate to form the air outlet channel. The second inclined segment forms the shielding part.

[0014] This technical solution provides an alternative approach where the air guide ribs are connected by a first and a second inclined section. This design is relatively simple, offers good airflow guidance, and can quickly direct airflow from inside the casing to the outside, improving both exhaust efficiency and heat dissipation. The serrated visual barrier formed by the second inclined section provides a large-area field-of-view obstruction rate from a lateral perspective, effectively reducing the visibility of internal components.

[0015] Adjacent air guide ribs are connected by horizontal ribs, and multiple horizontal ribs are arranged at vertical intervals.

[0016] In this technical solution, the horizontal rib connection structure enables the wind guide rib array to form a three-dimensional grid frame, which greatly improves the mechanical torsional stiffness and can withstand high wind speed impact without deformation.

[0017] The air-guiding heat dissipation component has an air inlet surface parallel to the air inlet area and an air outlet surface parallel to the air outlet area, and the air blowing direction of the cooling fan is perpendicular to the air inlet surface.

[0018] In this technical solution, the vertical arrangement of the air inlet and the cooling fan allows airflow to enter the heat dissipation component at a 90° angle, eliminating the incident angle loss caused by the traditional oblique blowing method and effectively improving fan efficiency. Combined with the air outlet parallel to the exhaust area, an L-shaped right-angle air duct is formed, which helps shorten the airflow path, reduce pressure drop loss caused by flow resistance, and make the airflow path smoother, thereby improving heat dissipation efficiency.

[0019] The projection of the air inlet surface onto the horizontal plane lies on a first straight line, the projection of the air outlet surface onto the horizontal plane lies on a second straight line, and the projection of the guide slope onto the horizontal plane lies on a third straight line. The first, second, and third straight lines intersect each other to form a triangular region, and the first straight line is perpendicular to the second straight line.

[0020] In this technical solution, a geometric model of the heat dissipation path is constructed using the triangular projection area formed by the first straight line (air inlet), the second straight line (air outlet), and the third straight line (guide slope). This optimizes airflow guidance and ensures that the airflow path from the air inlet area to the air outlet area is shorter and more precise. The perpendicular relationship between the first and second straight lines ensures a 90° turn in the airflow direction, while the inclination angle of the third straight line serves as a transition surface, allowing the airflow to turn smoothly and reducing turbulence intensity.

[0021] The air-guiding heat dissipation component is provided with multiple ventilation channels, and the guide slope guides the airflow blown into the ventilation channel by the cooling fan toward the air outlet channel.

[0022] In this technical solution, multiple ventilation channels increase the heat dissipation area of ​​the air-guiding heat sink, allowing the airflow to carry away more heat per unit time, which helps to improve heat dissipation efficiency.

[0023] The airflow cooling component includes a heat dissipation main board and multiple heat dissipation fins fixed on a first side of the heat dissipation main board. The cooling fins abut against a second side of the heat dissipation main board. The first side and two adjacent heat dissipation fins form the ventilation channel. The airflow guide slope is formed on the first side.

[0024] In this technical solution, the combined design of heat dissipation fins and heat dissipation main board achieves three-dimensional heat dissipation and significantly increases the heat dissipation area; the planar contact of the second side of the heat dissipation main board ensures the heat conduction efficiency with the cooling chip.

[0025] The countertop water purifier also includes a detachable protective cover installed on the outside of the housing, the protective cover covering the air inlet area, and the protective cover having a vent opening facing the air inlet area.

[0026] In this technical solution, the detachable protective cover achieves tool-free maintenance, and its ventilation design can block large-diameter dust particles while ensuring air intake, thus improving the dustproof effect.

[0027] Due to the adoption of the above technical solution, the technical effects achieved by this application are as follows: the separate design of the air inlet and outlet areas forms an independent air duct, and the outlet duct is designed to be inclined towards the air inlet area. Combined with the guide slope of the air-guiding heat dissipation component, a directional airflow heat dissipation path is formed, optimizing the airflow direction, preventing disordered diffusion of airflow within the housing, and preventing airflow from returning towards the cooling fan. The airflow does not disturb each other when passing through the air-guiding heat dissipation component, and the airflow concentrates on the high-temperature area of ​​the air-guiding heat dissipation component, quickly carrying heat out of the housing through the outlet duct, achieving a better heat dissipation effect. Simultaneously, the synergistic effect of the inclined outlet duct and the guide slope reduces the probability of airflow collision with the housing wall, reducing wind noise caused by turbulence. Furthermore, the shielding part obstructs the internal view of the housing, preventing users from seeing the inside of the housing from the outside, making the internal components invisible, significantly improving the appearance integrity and enhancing the machine's visual aesthetics.

[0052] In the embodiments of this application, a countertop water purifier is provided. For ease of explanation and understanding, the following content provided in this application is based on the illustrated product structure. Of course, those skilled in the art will understand that the above structure is only a specific example and illustrative illustration, and does not constitute a specific limitation on the technical solution provided in this application.

[0053] Reference Figures 1 to 10 As shown, the tabletop water purifier provided in this application includes a base 2 and a housing 1 mounted on the base 2. The housing 1 is equipped with a refrigeration system, which includes an ice chamber 3, a cooling plate 4 mounted on the ice chamber 3, and a heat dissipation component 5 for dissipating heat from the cooling plate 4. The housing 1 includes an air inlet area 11 and an air outlet area 12. A cooling fan 6 is provided between the air inlet area 11 and the heat dissipation component 5. The air inlet area 11 is provided with an air inlet channel 13, and the air outlet area 12 is provided with an air outlet channel 14 and a shield. The air outlet channel 14 is inclined toward the air inlet area 11. The heat dissipation component 5 is provided with a guide slope 51, which can guide the airflow blown by the cooling fan 6 toward the air outlet channel 14. The shield is inclined relative to the air outlet channel 14 to block the internal view of the housing 1.

[0054] This application does not limit the specific locations of the air inlet area 11 and the air outlet area 12 on the housing 1. In a preferred embodiment, the air inlet area 11 and the air outlet area 12 can be respectively arranged on two walls of the housing 1. This avoids the air inlet area 11 and the air outlet area 12 being concentrated on the same wall of the housing 1, which would result in too cramped space. It also facilitates better guidance of the airflow from the cooling fan 6, preventing the airflow from reversing and flowing back towards the air inlet area 11. Figures 1 to 4As shown, an embodiment is illustrated where the air inlet area 11 is located on the rear wall of the housing 1, and the air outlet area 12 is located on one side wall of the housing 1. This arrangement keeps the air outlet area 12 away from the water inlet area at the front of the machine, improving safety. When the cooling fan 6 is operating, it draws airflow from the outside through the air inlet area 11. The airflow passes through the air guide heat dissipation component 5 and is guided by the guide slope 51 to the air outlet area 12 for discharge outside the machine. Figure 4 The arrows shown schematically represent the airflow direction of the cooling fan 6 when it is working.

[0055] In this technical solution, the separate design of the air inlet area 11 and the air outlet area 12 forms an independent air duct. The air outlet duct 14 is designed to be inclined towards the air inlet area 11. Combined with the guide slope 51 of the air guide heat sink 5, a directional airflow cooling path is formed, optimizing the airflow direction and preventing disordered diffusion of airflow within the housing 1. The airflow will not return towards the cooling fan 6, and the airflow will not disturb each other when passing through the air guide heat sink 5. The airflow is concentrated and flows through the high-temperature area of ​​the air guide heat sink 5, quickly carrying the heat out of the housing 1 through the air outlet duct 14, achieving a better heat dissipation effect. Simultaneously, the synergistic effect of the inclined air outlet duct 14 and the guide slope 51 reduces the probability of airflow collision with the wall of the housing 1, reducing wind noise caused by turbulence. Furthermore, the shielding part obstructs the internal view of the housing 1, preventing users from seeing the inside of the housing 1 from the outside. The internal components of the housing 1 are not visible, significantly improving the appearance integrity and enhancing the machine's visual aesthetics.

[0056] Regarding the formation of the air outlet duct 14 and the structure of the shielding part, this application does not impose specific limitations. Based on the premise that the air outlet area 12 is located on one side wall of the housing 1, it can adopt any of the following embodiments:

[0057] Example 1: As Figures 3 to 6 As shown, the air outlet area 12 is provided with multiple parallel-arranged air guide ribs 15, and an air outlet channel 14 is formed between two adjacent air guide ribs 15. The air guide ribs 15 are at least partially inclined towards the air inlet area 11, and a shielding part is formed on the air guide ribs 15. In this technical solution, the array-type air outlet channel 14 is formed by multiple parallel-arranged inclined air guide ribs 15, which realizes uniform airflow distribution and accelerated discharge. The spacing design of adjacent air guide ribs 15 generates a pressure distribution effect, which makes the airflow form laminar flow in multiple parallel channels, which helps to increase the heat dissipation area of ​​the air duct and also helps to make the airflow distribution more uniform and avoid local overheating. In addition, by at least partially inclined, the air guide ribs 15, on the basis of forming an air outlet channel 14 inclined towards the air inlet area 11, also help to form a shielding structure, which can shield the view inside the housing 1, making it as difficult as possible for the user to see the inside of the housing 1 from the outside, thus improving the visual aesthetics of the machine.

[0058] Furthermore, such as Figures 3 to 5 and Figure 9As shown, the air guide rib 15 extends vertically. The projection of the air guide rib 15 onto the horizontal plane forms a Z-shaped structure consisting of an inner extension section 151, an outer extension section 152, and a connecting section 153 connected sequentially. The inner extension section 151 is located inside the housing 1, the outer extension section 152 is located outside the housing 1, and the connecting section 153 is inclined towards the air inlet area 11. Adjacent connecting sections 153 cooperate to form the air outlet channel 14, and the inner extension section 151 and the outer extension section 152 form a shielding portion. In specific implementations, based on the inclination of the connecting section 153 towards the air inlet area 11, both the inner extension section 151 and the outer extension section 152 of the Z-shaped air guide rib can extend along the extension direction of the side wall of the housing 1. The Z-shaped air guide rib forms a continuous zigzag structure on the horizontal projection plane, serving both airflow guidance and visual shielding functions. The vortex generated at the bend of the air guide rib 15 can disperse large-scale airflow clusters and reduce high-frequency noise. Simultaneously, the continuous ridges of the Z-shaped structure not only allow the connecting section 153 to form the air outlet channel 14, but also utilize the inclined inner extension section 151 and outer extension section 152 relative to the connecting section 153 to create an optical shielding surface in the frontal view, making the internal components of the housing 1 invisible and significantly improving the overall appearance integrity. Furthermore, the Z-shaped ribs are stronger than straight rib structures, significantly improving the deformation resistance of the air guide rib 15.

[0059] Example 2: Figure 6 and Figure 10 As shown, based on the vertical extension of the air guide rib 15, the difference between this embodiment and the Z-shaped air guide rib in Embodiment 1 is that the projection of the air guide rib 15 on the horizontal plane includes a first inclined segment 154 and a second inclined segment 155 connected at an angle. The first inclined segment 154 is inclined towards the air inlet area 11, and adjacent first inclined segments 154 cooperate to form an air outlet channel 14. The second inclined segment 155 forms a shielding part. In specific implementation, based on the first inclined segment 154 being inclined towards the air inlet area 11, the second inclined segment 155 can extend along the extension direction of the side wall of the housing 1. In this technical solution, another technical solution is provided where the air guide rib 15 is connected by the first inclined segment 154 and the second inclined segment 155. Compared with the Z-shaped air guide rib, this structure is simpler and has better air guiding performance. It can quickly guide the airflow from the inside of the housing 1 to the outside of the housing 1, and the improved exhaust efficiency can also effectively improve the heat dissipation efficiency. The sawtooth visual barrier formed by the second inclined segment 155 achieves a large field of view occlusion rate in the horizontal view, effectively reducing the visibility of the internal components of the housing 1.

[0060] In preferred embodiments, both Embodiment 1 and Embodiment 2 can be further configured such that adjacent air guide ribs 15 are connected by horizontal ribs 16, with multiple horizontal ribs 16 arranged at vertical intervals. Figure 5As shown, taking Example 1 as an example, the horizontal rib 16 connection structure enables the Z-shaped air guide rib array to form a three-dimensional grid frame, which greatly improves the mechanical torsional stiffness and can withstand high wind speed impact without deformation. In addition, in Example 2, although not shown, adjacent air guide ribs can also be connected by horizontal ribs.

[0061] As a preferred embodiment of this application, such as Figure 4 and Figure 7 As shown, the air-guiding heat dissipation component 5 has an air inlet surface 52 parallel to the air inlet area 11 and an air outlet surface 53 parallel to the air outlet area 12, and the air blowing direction of the cooling fan 6 is perpendicular to the air inlet surface 52.

[0062] In this technical solution, the vertical arrangement of the air inlet surface 52 and the cooling fan 6 allows the airflow to enter the heat sink 5 in a 90° direct blowing manner, eliminating the incident angle loss caused by the traditional oblique blowing method and effectively improving the fan efficiency. Combined with the air outlet surface 53 set parallel to the air outlet area 12, an L-shaped right-angle air duct is formed, which helps to shorten the airflow path, reduce pressure drop loss caused by flow resistance, and make the airflow path smoother, thereby improving heat dissipation efficiency.

[0063] Furthermore, such as Figure 7 As shown, the projection of the air inlet surface 52 onto the horizontal plane lies on the first straight line, the projection of the air outlet surface 53 onto the horizontal plane lies on the second straight line, and the projection of the guide slope 51 onto the horizontal plane lies on the third straight line. The first, second, and third straight lines intersect each other to form a triangular region, and the first straight line is perpendicular to the second straight line. Specifically, Figure 7 The dashed lines X, Y, and Z represent the first, second, and third straight lines, respectively. These three lines connect to form a triangle. In this technical solution, the geometric model of the heat dissipation path is constructed using the triangular projection area formed by the first straight line (inlet surface 52), the second straight line (outlet surface 53), and the third straight line (guide slope 51). The airflow enters the triangular area from one right-angled side (the first straight line), and then flows along the hypotenuse (the third straight line) towards the other right-angled side (the second straight line), optimizing the airflow direction and ensuring a shorter and more precise path from the inlet area 11 to the outlet area 12. The perpendicular relationship between the first and second straight lines ensures a 90° turn in the airflow direction, while the inclination angle of the third straight line serves as a transition surface, allowing the airflow to smoothly change direction and reducing turbulence intensity.

[0064] Regarding the structure of 5, in the preferred embodiment, such as Figure 4 and Figure 8As shown, the air-guiding heat sink 5 is provided with multiple ventilation channels 54. The guide slope 51 guides the airflow blown into the ventilation channels 54 by the cooling fan 6 towards the air outlet channel 14. In this technical solution, by providing multiple ventilation channels 54 in the air-guiding heat sink 5, the heat dissipation area of ​​the air-guiding heat sink 5 is increased, and the contact area between the airflow and the air-guiding heat sink 5 is increased. The airflow can carry away more heat per unit time, which helps to improve the heat dissipation efficiency. At the same time, it ensures that the airflow can flow orderly from the ventilation channels 54 to the air outlet channel 14.

[0065] Furthermore, such as Figure 8 As shown, the airflow-guiding heat sink 5 includes a heat sink main board 55 and multiple heat sink fins 56 fixed to a first side of the heat sink main board 55. A cooling fin 4 abuts against a second side of the heat sink main board 55. The first side and two adjacent heat sink fins 56 form a ventilation channel 54, and a guiding slope 51 is formed on the first side. This technical solution clarifies the specific structure of the airflow-guiding heat sink 5, which consists of a heat sink main board 55 and multiple heat sink fins 56. The heat sink fins 56 and the heat sink main board 55 form a ventilation channel 54, and the guiding slope 51 is formed on the first side. This structure greatly increases the heat dissipation area and improves heat dissipation performance. Simultaneously, the cooling fin 4 abuts against the second side of the heat sink main board 55, enabling more effective heat transfer. Furthermore, the combined design of the heat sink fins 56 and the heat sink main board 55 achieves three-dimensional heat dissipation, significantly increasing the heat dissipation area; the planar contact of the second side of the heat sink main board 55 ensures efficient heat conduction with the cooling fin 4.

[0066] As a preferred embodiment of this application, such as Figures 1 to 3 As shown, the countertop water purifier also includes a detachable protective cover 7 installed on the outside of the housing 1. The protective cover 7 covers the air intake area 11 and has a vent opening facing the air intake area 11. Figure 1 and Figure 3 The image shows the protective cover 7 installed on the housing 1, as shown. Figure 2 The image shows the protective cover 7 removed from the housing 1. In this technical solution, the ventilation design of the protective cover 7, while ensuring sufficient airflow, can block large-diameter particles, preventing dust and debris from entering the air intake area 11 and the heat dissipation system, thus improving dustproof performance. Preferably, the protective cover 7 can be detachably installed on the housing 1 using a snap-fit ​​method, achieving tool-free disassembly and maintenance.
