Description

Technical Field

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

[0002] With economic development and improved living standards, consumers are paying more and more attention to healthy water and drinking water, and their requirements for water use are also getting higher and higher. As a water treatment device that can deeply filter and purify water according to its usage requirements, water purifiers are gaining increasing recognition and favor from consumers.

[0003] Water purifiers, which can provide both room temperature and hot water, are gradually becoming an indispensable product in household appliances. These purifiers typically include a filter element, a heating element, and a water outlet. Their working principle is that the filter element directly outputs pure water after filtering tap water, or the heating element heats the water before outputting it, thus enabling the dispensing of either room temperature or hot water when connected to the water outlet.

[0004] Existing water purifiers have a relatively long outlet pipe between the heating element and the water outlet. When the hot water output from the heating element flows in the outlet pipe, it loses a lot of heat, causing the hot water temperature to drop. This results in a significant difference between the heating temperature of the heating element and the water temperature at the outlet, making it difficult to meet users' needs for hot water and affecting the user experience. Utility Model Content

[0005] This application provides a water purifier to address the technical problem in existing water purifiers where the hot water output from the heating element loses a significant amount of heat as it flows toward the water outlet, resulting in a decrease in the hot water temperature and a large difference between the heating temperature of the heating element and the water temperature at the water outlet.

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

[0007] A water purifier includes a heating element, a water outlet, a housing, and a main support disposed within the housing. The main support includes a filter element mounting portion for mounting a filter element and a booster pump mounting portion for mounting a booster pump. The filter element mounting portion and the booster pump mounting portion are connected side-by-side in a transverse direction. The heating element and the water outlet are both located directly in front of the filter element mounting portion. The heating element is mounted on the filter element mounting portion, and the water outlet is higher than the heating element. The water outlet has a hot water inlet, and the top of the heating element has a hot water outlet pipe communicating with the hot water inlet.

[0008] In this technical solution, both the heating element and the water outlet are located directly in front of the filter element mounting section, on the same side of the machine. Compared to arranging the heating element and water outlet on opposite sides, this same-side arrangement helps to shorten the distance between them, thereby shortening the fluid path for hot water to travel from the heating element to the water outlet. Furthermore, with the water outlet higher than the heating element, placing the hot water outlet of the heating element at the top minimizes the distance between the hot water outlet pipe and the hot water inlet of the water outlet, further shortening the fluid path for hot water to travel from the heating element to the water outlet. This reduces heat loss during hot water output, minimizes the temperature difference between the heating element and the water outlet temperature, increases the water temperature, ensures precise temperature control, and improves the user experience. In addition, to avoid the overall machine's center of gravity shifting to one side due to too many components such as the heating element and water outlet being concentrated on one side of the filter element mounting section, causing imbalance, the filter element mounting section and the booster pump mounting section are connected side by side in the horizontal direction. This allows the relatively heavy booster pump to balance the weight on the side where the booster pump mounting section is located, keeping the overall center of gravity as central as possible, improving stability, and reducing the risk of tipping over.

[0009] The hot water outlet pipe extends vertically, and the water outlet is provided with a hot water inlet pipe that forms the hot water inlet. The hot water inlet pipe is arranged perpendicularly to the hot water outlet pipe, and the hot water outlet pipe is connected to the hot water inlet pipe through an L-shaped water connector.

[0010] In this technical solution, the hot water outlet pipe extends vertically and can extend directly toward the water outlet, reducing the distance between it and the water outlet. The hot water inlet pipe and the hot water outlet pipe are arranged vertically, which facilitates connection through a simple L-shaped water connector. On the one hand, this simplifies the connection process between the heating element and the water outlet, and on the other hand, it helps to shorten the water flow path between the hot water outlet pipe and the hot water inlet pipe, reducing heat loss during the hot water discharge process.

[0011] The water purifier also includes a straight water pipe connector and a vertical PE pipe. The lower end of the PE pipe and the hot water outlet pipe are respectively inserted into the two ends of the straight water pipe connector, and the upper end of the PE pipe and the hot water inlet pipe are respectively inserted into the two ends of the L-shaped water pipe connector.

[0012] In this technical solution, the PE pipe is connected to the hot water outlet pipe via a straight water connector, making installation convenient and quick. The PE pipe is made of polyethylene plastic, which is characterized by high temperature resistance and high strength. By using the PE pipe to replace the silicone hose in connecting the hot water outlet pipe and the L-shaped water connector, which in turn connects to the hot water inlet pipe, a silicone-free water path design is achieved from the heating element to the water outlet, avoiding the absorption of odors by silicone that could cause unpleasant tastes in the drinking water.

[0013] A water baffle is provided below the hot water inlet. The projection of the hot water inlet on the horizontal plane is located within the projection range of the water baffle on the horizontal plane. The water baffle is provided with a drain hole. The projection of the drain hole on the horizontal plane falls outside the projection of the heating element on the horizontal plane.

[0014] In this technical solution, when the hot water inlet leaks, the leaking water is caught by the water baffle. The water caught by the water baffle is discharged through the drain hole. Since the projection of the drain hole on the horizontal plane falls outside the projection of the heating element on the horizontal plane, the discharged water is prevented from contacting the heating element, which could cause water leakage and damage to the wiring terminals, thus improving the safety of the water purifier.

[0015] The water-blocking component is a flexible structure with a sleeve hole, which is fitted onto the hot water outlet pipe.

[0016] In this technical solution, a water-blocking component is fitted onto the hot water outlet pipe, surrounding it to create a water-blocking effect. The connection point between the hot water outlet pipe and the PE pipe is located above the water-blocking component. When leakage occurs at this connection point, the water flows downwards to the water-blocking component and towards the drain hole, eventually being discharged through the drain hole. The water flowing down from the drain hole stays away from the wiring terminals of the heating element and does not flow onto the heating element, thus preventing the leaked water from causing water contact, leakage, or damage to the wiring terminals, thereby improving the safety of the water purifier.

[0017] The water-blocking component is provided with a limiting recess, and the filter element mounting part cooperates with the limiting recess to restrict the rotation of the water-blocking component relative to the hot water outlet pipe.

[0018] In this technical solution, the water-blocking component is limited by the filter element installation part to prevent the water-blocking component from rotating around the hot water outlet pipe and changing the position of the drain hole, so as to ensure that when leakage occurs, the water-blocking component can drain water according to the preset position of the drain hole when the machine is installed.

[0019] The edge of the water-blocking component is provided with water-blocking ribs, which form an upward-facing water-blocking groove, and the drainage hole is located inside the water-blocking groove.

[0020] In this technical solution, by forming a water-blocking groove with the water-blocking ribs facing upwards, on the one hand, when the water-blocking groove is used to collect the leaking water, the water-blocking ribs block the water droplets splashing outwards, preventing the water droplets from splashing towards the heating element. On the other hand, the space inside the water-blocking groove can hold more water, thus minimizing excessive water leakage in a short period of time, which could cause water to overflow from the water-blocking component.

[0021] The filter element mounting part is provided with a protruding positioning plate, the positioning plate is provided with multiple positioning holes, and the heating element is provided with positioning posts with screw holes corresponding to the multiple positioning holes one by one. The heating element is detachably installed on the positioning plate by screws passing through the positioning holes and the screw holes.

[0022] In this technical solution, the heating element is fixed and supported by a protruding positioning plate and screws, making installation convenient, stable and reliable.

[0023] The outer casing is equipped with a display unit, which includes a module housing and a display module disposed within the module housing. The module housing is provided with a decorative cylinder, and the water outlet is installed inside the decorative cylinder.

[0024] In this technical solution, the water outlet is installed inside the decorative cylinder, forming a hidden installation design that enhances the visual aesthetics. Furthermore, the water outlet is supported by the display unit to prevent it from bending downwards due to gravity.

[0025] The water purifier also includes a base plate, the outer shell is connected to the base plate, the booster pump mounting part is located close to the base plate, and the main bracket also includes an electronic control board mounting part located above the booster pump mounting part and used for mounting the electronic control board.

[0026] In this technical solution, the heavier booster pump is positioned lower, which lowers the center of gravity of the entire machine and helps to improve structural stability. Space is reserved above the booster pump mounting section for installing the electrical control board. The electrical control board is installed in the electrical control board mounting section, positioned higher up and away from the booster pump and other water circuit components below, reducing the risk of water leakage to the electrical control board.

[0027] Due to the adoption of the above technical solution, the technical effects achieved by this application are as follows: the heating element and the water outlet are both located directly in front of the filter element mounting section, and both are located on the same side of the machine. Compared with arranging the heating element and the water outlet on opposite sides, arranging them on the same side helps to shorten the distance between them, thereby shortening the fluid path of hot water from the heating element to the water outlet. Moreover, with the water outlet higher than the heating element, by placing the hot water outlet of the heating element at the top, the distance between the hot water outlet and the hot water inlet of the water outlet is minimized, further shortening the fluid path of hot water from the heating element to the water outlet, reducing the heat loss when hot water is dispensed, reducing the difference between the heating temperature of the heating element and the water temperature of the water outlet, increasing the water temperature, ensuring precise temperature control of water dissipation, and improving the user experience. In addition, to avoid the overall machine's center of gravity shifting to one side due to too many components such as the heating element and water outlet being concentrated on one side of the filter element mounting section, causing imbalance, the filter element mounting section and the booster pump mounting section are connected side by side in the horizontal direction. This allows the relatively heavy booster pump to balance the weight on the side where the booster pump mounting section is located, keeping the overall center of gravity as central as possible, improving stability, and reducing the risk of tipping over.

Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0056] In the embodiments of this application, a 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.

[0057] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the water purifier provided in this application includes a heating element 1, a water outlet 2, a housing 3, and a main support 4 disposed within the housing 3. The main support 4 includes a filter element mounting part 41 for mounting a filter element 5 and a booster pump mounting part 42 for mounting a booster pump 6. The filter element mounting part 41 and the booster pump mounting part 42 are connected side by side in a transverse direction. The heating element 1 and the water outlet 2 are both located directly in front of the filter element mounting part 41. The heating element 1 is mounted on the filter element mounting part 41. The water outlet 2 is higher than the heating element 1. The water outlet 2 is provided with a hot water inlet. The top of the heating element 1 is provided with a hot water outlet pipe 11 communicating with the hot water inlet.

[0058] In this water purifier, the booster pump 6 pumps raw water to the filter element 5 for filtration. The purified water produced by the filter element 5 is then sent to the heating element 1 for heating into hot water. The heating element 1 then delivers the hot water to the outlet 2 for discharge. The term "front" here refers to a relative positional concept, specifically the side of the water purifier that is convenient for the user to access water, adjust the temperature, and select functions.

[0059] In this technical solution, both the heating element 1 and the water outlet 2 are located directly in front of the filter element mounting section 41, on the same side of the machine. Compared to arranging the heating element 1 and the water outlet 2 on opposite sides, arranging them on the same side helps to shorten the distance between them, thereby shortening the fluid path for hot water to be transported from the heating element 1 to the water outlet 2. Moreover, with the water outlet 2 higher than the heating element 1, by placing the hot water outlet pipe 11 of the heating element 1 at the top, the distance between the hot water outlet and the hot water inlet of the water outlet 2 is minimized, further shortening the fluid path for hot water to be transported from the heating element 1 to the water outlet 2, reducing the heat loss when hot water is dispensed, reducing the difference between the heating temperature of the heating element 1 and the outlet water temperature of the water outlet 2, increasing the outlet water temperature, ensuring precise temperature control of water dissipation, and improving the user experience. Furthermore, to avoid the excessive concentration of components such as the heating element 1 and the water outlet 2 on one side of the filter element mounting section 41, causing the overall center of gravity to shift to one side and become unbalanced, the filter element mounting section 41 and the booster pump mounting section 42 are connected side-by-side laterally. This allows the relatively heavy booster pump 6 to balance the weight on the side where the booster pump mounting section 42 is located, thus keeping the overall center of gravity as central as possible, improving stability, and reducing the risk of tipping. In a preferred embodiment, the filter element mounting section 41 can be provided with a cylindrical structure with an assembly cavity 411. The filter element 5 is installed in the assembly cavity 411, which limits the position of the filter element 5, ensuring stable installation and facilitating plug-in filter element replacement.

[0060] As a preferred embodiment of this application, such as Figure 4 and Figure 5 As shown, the hot water outlet pipe 11 extends vertically, and the water outlet 2 is provided with a hot water inlet pipe 21 forming the hot water inlet. The hot water inlet pipe 21 is arranged perpendicularly to the hot water outlet pipe 11, and the hot water outlet pipe 11 is connected to the hot water inlet pipe 21 through an L-shaped water connector 7. Specifically, if the vertical distance between the heating element 1 and the water outlet 2 allows, the hot water outlet pipe 11 can be directly connected to the L-shaped water connector 7. If the vertical distance between the heating element and the water outlet 2 needs to be increased, the hot water outlet pipe 11 can be indirectly connected to the L-shaped water connector 7, for example, by connecting a short pipe between them. In this technical solution, the hot water outlet pipe 11 extends vertically and can extend directly toward the water outlet 2, reducing the distance between it and the water outlet 2. The hot water inlet pipe 21 is arranged perpendicularly to the hot water outlet pipe 11, which facilitates connection through a simple L-shaped water connector 7. This simplifies the connection process between the heating element 1 and the water outlet 2, and also helps to shorten the water flow path between the hot water outlet pipe 11 and the hot water inlet pipe 21, reducing heat loss during hot water discharge.

[0061] Furthermore, such as Figure 4 and Figure 5As shown, the water purifier also includes a straight water connector 8 and a vertical PE pipe 9. The lower end of the PE pipe 9 and the hot water outlet pipe 11 are respectively inserted into the two ends of the straight water connector 8, and the upper end of the PE pipe 9 and the hot water inlet pipe 21 are respectively inserted into the two ends of the L-shaped water connector 7. In this technical solution, the PE pipe 9 and the hot water outlet pipe 11 are connected through the straight water connector 8, which is convenient and quick to install. The PE pipe 9 is made of polyethylene plastic, which has the characteristics of high temperature resistance and high strength. By using the PE pipe 9 to replace the silicone hose to connect the hot water outlet pipe 11 and the L-shaped water connector 7, and the L-shaped water connector 7 to connect the hot water inlet pipe 21, a silicone-free water pipe design is achieved from the heating element 1 to the water outlet 2, avoiding the absorption of odors by silicone which would cause the drinking water to have an odor. In a preferred embodiment, the hot water outlet pipe 11 can be made of metal, specifically high-strength stainless steel pipe, copper pipe or other suitable structure. Compared with plastic pipe, the structure is more stable and more heat-resistant. The straight water pipe connector 8 can also be made of high-temperature resistant metal connector.

[0062] As a preferred embodiment of this application, such as Figures 1 to 5 As shown, a water baffle 100 is provided below the hot water inlet. The projection of the hot water inlet on the horizontal plane is located within the projection range of the water baffle 100 on the horizontal plane. The water baffle 100 is provided with a drain hole 101, and the projection of the drain hole 101 on the horizontal plane falls outside the projection of the heating element 1 on the horizontal plane. Those skilled in the art will understand that, due to various factors such as processing errors, assembly errors, and the difficulty in maintaining constant water pressure in the water circuit, the water connection point between the hot water outlet pipe and the outlet of the heating element is often a location with a high risk of leakage. Although some water purifiers can improve the above problems to some extent by setting some sealing rings, the sealing performance may be lost due to the failure of the sealing rings, resulting in leakage. Once leakage occurs, water flows downwards to the heating element 1, easily causing water to come into contact with and leak electricity or even damage many of the wiring terminals on the heating element 1. Therefore, by setting up the water-blocking component 100, when water leaks from the hot water inlet, especially when water leaks at the connection between the hot water inlet pipe 21 and the L-shaped water connector 7 in the aforementioned embodiment, the leaking water is caught by the water-blocking component 100. The water caught by the water-blocking component 100 is discharged through the drain hole 101. Since the projection of the drain hole 101 on the horizontal plane falls outside the projection of the heating element 1 on the horizontal plane, the discharged water is prevented from contacting the heating element 1, causing water leakage and damage to the wiring terminals, thus improving the safety of the water purifier.

[0063] Furthermore, such as Figure 5As shown, the water-blocking component 100 is a flexible structure with a sleeve hole 102, which is fitted onto the hot water outlet pipe 11. In this technical solution, by fitting the water-blocking component 100 onto the hot water outlet pipe 11, the water-blocking component 100 surrounds the hot water outlet pipe 11, forming a water-blocking effect. The connection point between the hot water outlet pipe 11 and the PE pipe 9 is located above the water-blocking component 100. When leakage occurs at this connection point, the water flows downward to the water-blocking component 100 and towards the drain hole 101, eventually being discharged through the drain hole 101. The water flowing down from the drain hole 101 stays away from the wiring terminals of the heating element 1 and does not flow onto the heating element 1, thereby preventing the leaked water from causing water contact leakage and damage to the wiring terminals, and improving the safety of the water purifier. In a preferred embodiment, the water-blocking component 100 may be made of flexible silicone rubber. Silicone rubber has good high-temperature resistance and can cope with the high temperature when hot water is coming out of the hot water outlet pipe 11. In addition, silicone rubber also has good flexible resilience, so that the water-blocking component 100 can hold the hot water outlet pipe 11 tightly and avoid water leakage gaps between the inner wall of the sleeve hole 102 and the hot water outlet pipe 11.

[0064] As a preferred embodiment, such as Figure 2 , Figure 3 and Figure 4 As shown, the water-blocking component 100 is provided with a limiting recess 103. The filter element mounting part 41 cooperates with the limiting recess 103 to restrict the rotation of the water-blocking component 100 relative to the hot water outlet pipe 11. Specifically, in the embodiment where the filter element mounting part 41 is a cylindrical structure, the limiting recess 103 can be constructed as an arc-shaped groove that fits the outer peripheral surface of the cylindrical structure. In this technical solution, the water-blocking component 100 is limited by the filter element mounting part 41 to prevent the water-blocking component 100 from rotating around the hot water outlet pipe 11 and changing the position of the drain hole 101, ensuring that when leakage occurs, the water-blocking component 100 can drain water according to the preset position of the drain hole 101 during installation.

[0065] As a preferred embodiment, such as Figure 5 As shown, the edge of the water-blocking component 100 is provided with water-blocking ribs 104, which form an upward-facing water-blocking groove. The drain hole 101 is located inside the water-blocking groove. In this technical solution, by making the water-blocking ribs 104 form an upward-facing water-blocking groove, on the one hand, when the water-blocking groove is used to collect leaked water, the water-blocking ribs 104 block the water droplets splashed outward, preventing the water droplets from splashing towards the heating element 1. On the other hand, the space inside the water-blocking groove can hold more water, minimizing excessive leakage in a short period of time that could cause water to overflow from the water-blocking component 100.

[0066] As a preferred embodiment of this application, such as Figure 3As shown, the filter element mounting part 41 is provided with a protruding positioning plate 412. The positioning plate 412 has multiple positioning holes. The heating element 1 is provided with positioning posts with screw holes corresponding to the multiple positioning holes. The heating element 1 is detachably installed on the positioning plate 412 by screws 200 passing through the positioning holes and the screw holes. Specifically, the figure shows an embodiment with one positioning plate 412 at the top and one at the bottom. Each positioning plate 412 has multiple positioning holes, and the screws 200 fix the heating element 1 to the positioning plate 412. In this technical solution, the heating element 1 is fixedly supported by the protruding positioning plate 412 and the screws 200, which makes the installation convenient, stable and reliable.

[0067] As a preferred embodiment of this application, such as Figure 6 and Figure 7 As shown, the outer casing 3 is equipped with a display unit 300. The display unit 300 includes a module housing 301 and a display module disposed within the module housing 301. The module housing 301 is provided with a decorative cylinder 302, and the water outlet 2 is installed inside the decorative cylinder 302. Specifically, the display module can be used for displaying and selecting water purifier functions. An installation area can be provided on the top front side of the outer casing 3, and the display unit 300 can be installed within the installation area. Installing the water outlet 2 inside the decorative cylinder 302 forms a hidden installation design, enhancing the visual aesthetics. Moreover, the display unit 300 supports the water outlet 2, preventing it from bending downwards due to gravity.

[0068] As a preferred embodiment of this application, such as Figure 1 , Figure 3 and Figure 6 As shown, the water purifier also includes a base plate 400, the outer casing 3 is connected to the base plate 400, the booster pump mounting part 42 is located close to the base plate 400, and the main support 4 also includes an electronic control board mounting part 43 located above the booster pump mounting part 42 for mounting the electronic control board 500. In this technical solution, the heavier booster pump 6 is positioned lower, which lowers the center of gravity of the entire machine, helping to improve structural stability. Space is reserved above the booster pump mounting part 42 for mounting the electronic control board 500. The electronic control board 500 is mounted on the electronic control board mounting part 43, positioned higher and away from the booster pump 6 and other water circuit components below, reducing the risk of water leakage to the electronic control board 500.
