DETAILED DESCRIPTION

[0029] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0030] With the improvement of health awareness and the trend of miniaturization of living space, pure drinking products need to be equipped with more functions on smaller models to meet the drinking needs of different users. In related technologies, the raw water tank is usually set at the back or side of the product, and is mostly slender, which is not convenient for users to take and put. In addition, the large model of the product cannot better accommodate the needs of product function expansion and home use scenarios. Based on this, the present invention optimizes the layout of the drinking water equipment, facilitates the miniaturization design of the drinking water equipment, and facilitates the taking and placing of the raw water tank.

[0031] Combination Figure 1 and Figure 2 The drinking water purification device 100 according to an embodiment of the present invention includes: a raw water tank 10 and a filter component 20. The filter component 20 is connected to the raw water tank 10 and is used to filter the fluid in the raw water tank 10. The filter component 20 is arranged below the raw water tank 10.

[0032] The drinking water purification device 100 further includes a clean water tank 30 , which is connected to the filter assembly 20 , and is disposed in front of the raw water tank 10 .

[0033] Specifically, the raw water tank 10 can be used to store tap water, and the filter assembly 20 can filter the water in the raw water tank 10, and the water filtered by the filter assembly 20 can be passed into the clean water tank 30. The filter assembly 20 is arranged below the raw water tank 10, that is, the filter assembly 20 and the raw water tank 10 are arranged in the up-down direction, and the raw water tank 10 is arranged above the water purification device 100, which is convenient for taking and placing the raw water tank 10. It can be understood that the raw water tank 10 is filled with tap water. After long-term use, the raw water tank 10 may contain minerals and impurities. The raw water tank 10 is arranged above the filter assembly 20, which can facilitate the disassembly and cleaning of the raw water tank 10, and the user can take and place water, etc.; in addition, the raw water tank 10 is arranged above the filter assembly 20, and the clean water tank 30 is arranged in front of the raw water tank 10, which can reduce the width of the clean drinking device 100 and facilitate the miniaturization design of the clean drinking device 100.

[0034] Among them, the raw water tank 10, the filter component 20 and the clean water tank 30 can be combined into a clean drinking module of the clean drinking device 100. By integrating the filter component 20, the raw water tank 10 and the clean water tank 30 on one side, it is convenient to miniaturize the design of the clean drinking device 100 and to expand other modules in the clean drinking device 100.

[0035] Exemplarily, the pure water drinking device 100 may further include a cold and hot water module, which may have functions such as heating, refrigerating, and ice making. The pure water drinking module and the cold and hot water module may be distributed on the left and right sides of the pure water drinking device 100. Combining the foregoing, by arranging the raw water tank 10 above the filtering component 20 and the pure water tank 30 in front of the raw water tank 10, the width dimension of the pure water module can be reduced, facilitating the expansion of the cold and hot water module on the pure water drinking device 100, making the overall structure of the pure water drinking device 100 more compact and facilitating the miniaturized design of the product. Among them, the pure water tank 30 may be connected to the cold and hot water module so as to introduce at least a part of the pure water in the pure water tank 30 into the cold and hot water module to heat, refrigerate, make ice, etc. for the pure water, enriching the functions of the pure water drinking device 100.

[0036] In addition, the raw water tank 10 may be provided with a water filling port through which water can be added to the raw water tank 10, or the raw water tank 10 may be connected to a municipal pipeline through which municipal tap water can be introduced into the raw water tank 10. For example, when the user's usage scenario has the condition of connecting to a municipal pipeline, the raw water tank 10 may be connected to the municipal pipeline, or when the user's usage scenario does not have the condition of connecting to a municipal pipeline, the pure water drinking device 100 can be used by adding water to the raw water tank 10 to meet the usage requirements in different usage scenarios.

[0037] For the pure water drinking device 100 according to an embodiment of the present invention, by arranging the filtering component 20 below the raw water tank 10 and connecting the pure water tank 30 in front of the raw water tank 10, it is convenient to take out and place the raw water tank 10, and the width dimension of the pure water drinking device 100 can be reduced, facilitating the miniaturized design of the pure water drinking device 100.

[0038] Combined with Figure 2 and Figure 3 , in some embodiments of the present invention, the pure water drinking device 100 further includes a mounting seat 40, which is arranged above the filtering component 20 and has a mounting cavity with an open top. The raw water tank 10 is removably installed in the mounting cavity. The mounting seat 40 can support and fix the raw water tank 10, and since the raw water tank 10 is arranged above the filtering component 20, it is convenient to take out and place the raw water tank 10, and thus it is convenient for the user to add water, change water, or clean the raw water tank 10, etc. Exemplarily, the raw water tank 10 can be taken out and placed in the mounting cavity in the vertical direction. In addition, the filtering component 20 is arranged below the mounting seat 40, and the mounting seat 40 separates the filtering component 20 and the raw water tank 10 to reduce the mutual influence and improve the structural stability of the pure water drinking device 100.

[0039] Combined with Figure 2 and Figure 3Further, the bottom wall of the raw water tank 10 is provided with a first water outlet connector 11, and the bottom wall of the mounting seat 40 is provided with a second water outlet connector 41, and the first water outlet connector 11 and the second water outlet connector 41 are detachably connected. Exemplarily, the second water outlet connector 41 can be connected to the filter assembly 20 through a pipeline, and after the raw water tank 10 is installed in the mounting cavity, the first water outlet connector 11 and the second water outlet connector 41 are connected, so as to facilitate the introduction of water from the raw water tank 10 into the filter assembly 20.

[0040] Exemplarily, an automatic sealing valve may be provided in the first water outlet connector 11, and a trigger structure may be provided in the second water outlet connector 41. For example, the valve may be a spring sealing plug valve. After the raw water tank 10 is installed into the mounting seat 40, the trigger structure pushes open the spring sealing structure in the valve, and the valve opens to connect the first water outlet connector 11 and the second water outlet connector 41. When the raw water tank 10 is taken out of the mounting cavity, the first water outlet connector 11 and the second water outlet connector 41 are separated, and the spring in the valve pushes the sealing plug to reset, and the valve closes to block the water flow, thereby preventing water in the raw water tank 10 from leaking out when the raw water tank 10 is taken out.

[0041] In some embodiments of the present invention, the bottom wall of the raw water tank 10 is provided with a first water return joint 12, and the bottom wall of the mounting seat 40 is provided with a second water return joint 42, and the first water return joint 12 is detachably connected to the second water return joint 42. Specifically, after the raw water tank 10 is loaded into the mounting seat 40, the first water return joint 12 and the second water return joint 42 are connected, so that the filtered waste water or the pure water stored for a long time in the drinking water purification device 100 can be discharged into the raw water tank 10.

[0042] Exemplarily, an automatic sealing valve may be provided in the first return water joint 12, and a trigger structure may be provided in the second return water joint 42. For example, the valve may be a spring sealing plug valve. After the raw water tank 10 is loaded into the mounting seat 40, the trigger structure pushes open the spring sealing structure in the valve, and the valve opens to connect the first return water joint 12 and the second return water joint 42. When the raw water tank 10 is taken out from the mounting seat 40, the first return water joint 12 and the second return water joint 42 are separated, and the spring in the valve pushes the sealing plug to reset, and the valve closes to block the water flow, thereby preventing water in the raw water tank 10 from leaking out when the raw water tank 10 is taken out.

[0043] In some embodiments of the present invention, the drinking water purification device 100 further includes a refrigeration component, which includes a cold water chamber, which is connected to the first water return joint 12 and is used to discharge the stale water in the cold water chamber into the raw water tank 10. Exemplarily, the cold water chamber can be used to store and provide cold water, and the cold water chamber can be connected to the first water return joint 12 through a pipeline. It can be understood that the cold water in the cold water chamber is prone to produce odor after being stored for a long time. When the cold water storage time reaches a predetermined condition, the stale water in the cold water chamber can be discharged from the first water return joint 12 into the raw water tank 10 instead of being directly provided to the user. The water in the raw water tank 10 is then re-transported to the cold water chamber after a series of treatments, and the water in the cold water chamber can be used to make and or provide cold water.

[0044] Among them, the refrigeration component can cool the pure water filtered by the filter component 20, and can also make ice from the pure water. For example, the refrigeration component can also have an ice storage chamber and an ice making chamber. The ice making chamber is arranged above the ice storage chamber. The ice making chamber is used to make ice. The cold water chamber can provide cold water to the ice making chamber. The ice storage chamber can store ice cubes. The ice storage chamber is arranged above the cold water chamber, and a through hole connected to the cold water chamber is provided at the bottom of the ice storage chamber. The water in the ice storage chamber can flow into the cold water chamber through the through hole to drain the moisture on the surface of the ice cubes and avoid affecting the ice cubes. When the water in the cold water chamber is stored for a long time, it is easy to produce odor. By setting the aforementioned first return water joint 12, it is convenient to discharge the stale water in the cold water chamber into the raw water tank 10.

[0045] In addition, the pure drinking water device 100 may include a pure drinking water module and a hot and cold water module, wherein the pure drinking water module includes the aforementioned raw water tank 10, filter assembly 20 and pure water tank 30, and the hot and cold water module may include the aforementioned refrigeration assembly. The pure drinking water module and the hot and cold water module may be distributed on the left and right sides of the pure drinking water device 100, so that the structure of the pure drinking water device 100 is compact and convenient for modular design of the product.

[0046] In some embodiments of the present invention, the filter assembly 20 includes a reverse osmosis filter element, the inlet of the reverse osmosis filter element is directly or indirectly connected to the first water outlet connector 11, the outlet of the reverse osmosis filter element is connected to the clean water tank 30, and the waste water outlet of the reverse osmosis filter element is connected to the first return water connector 12. Specifically, the inlet of the reverse osmosis filter element can be directly connected to the first water outlet connector 11, that is, the water in the raw water tank 10 can directly enter the reverse osmosis filter element for filtration; or, the inlet of the reverse osmosis filter element can be indirectly connected to the first water outlet connector 11. Exemplarily, the filter assembly 20 can also include a pre-filter element, and the tap water in the raw water tank 10 first enters the pre-filter element through the first water outlet connector 11 for filtration and then enters the reverse osmosis filter element for filtration. The pure water filtered by the reverse osmosis filter element can enter the clean water tank 30, and the waste water filtered by the reverse osmosis filter element can be discharged into the raw water tank 10 through the first return water connector 12.

[0047] Combination Figure 3 and Figure 4 In some embodiments of the present invention, a boss 13 is provided on the bottom wall of the raw water tank 10, and the first water outlet joint 11 and the first water return joint 12 are provided on the top wall of the boss 13. In other words, the positions of the first water outlet joint 11 and the first water return joint 12 are higher than the bottom wall of the raw water tank 10. It can be understood that after the wastewater is discharged into the raw water tank 10 through the first water return joint 12, the specific gravity of minerals and impurities in the wastewater is relatively high, so the wastewater is more likely to flow downward and flow to the bottom of the boss 13. The position of the first water outlet joint 11 is relatively high, which can reduce the proportion of wastewater entering the filter assembly 20 from the first water outlet joint 11.

[0048] In addition, the first water outlet joint 11 and the first water return joint 12 are arranged on the top wall of the boss 13, and the positions of the first water outlet joint 11 and the first water return joint 12 are relatively high. For example, when the raw water tank 10 is taken out and placed on the table, the first water outlet joint 11 and the first water return joint 12 can be avoided from contacting with the table and affecting it.

[0049] Combination Figure 3 and Figure 4 Further, the mounting seat 40 is provided with a positioning protrusion 43, the second water outlet joint 41 and the second water return joint 42 are provided in the positioning protrusion 43, a part of the bottom wall of the raw water tank 10 is protruded upward to form a boss 13 located inside the raw water tank 10 and a positioning groove 13a located outside the raw water tank 10, and the positioning protrusion 43 is detachably provided in the positioning groove 13a. The positioning protrusion 43 and the positioning groove 13a cooperate to improve the installation efficiency of the raw water tank 10 and the mounting seat 40. In addition, when the raw water tank 10 is docked with the mounting seat 40, the positioning protrusion 43 is provided in the positioning groove 13a, which can improve the connection stability between the raw water tank 10 and the mounting seat 40.

[0050] Among them, the second water outlet joint 41 and the second water return joint 42 are arranged on the positioning protrusion 43, and the first water outlet joint 11 and the second water return joint 42 are arranged on the boss 13, so that when the raw water tank 10 is docked with the mounting seat 40, the positioning groove 13a and the positioning protrusion 43 can be quickly docked, thereby facilitating the precise positioning of the first water outlet joint 11 and the second water outlet joint 41, and the precise positioning of the first return water joint 12 and the second return water joint 42, thereby avoiding the influence of the misalignment of the docking of the raw water tank 10 and the mounting seat 40 on the joint.

[0051] Combination Figure 4 In some embodiments of the present invention, the first water return connector 12 may be connected to a third filter element 15, and the third filter element 15 is disposed in the raw water tank 10. When the stale water in the cold water chamber and / or the waste water of the reverse osmosis filter element enter the raw water tank 10 from the first water return connector 12, the third filter element 15 may filter the stale water and / or the waste water of the reverse osmosis filter element to improve the water quality. For example, the third filter element 15 may be an activated carbon filter element.

[0052] Combination Figure 3 and Figure 4 In some embodiments of the present invention, a guide rib 44 is provided on the inner side of the front side wall of the mounting seat 40, and a guide groove 14 is provided on the front wall surface of the raw water tank 10. The guide rib 44 and the guide groove 14 are adapted to each other and extend in the up-down direction, and the guide rib 44 can be detached and arranged in the guide groove 14. Specifically, the raw water tank 10 can be docked with the mounting seat 40 in the direction from top to bottom. During the installation process of the raw water tank 10, the guide groove 14 and the guide rib 44 cooperate to position and limit the raw water tank 10, ensuring that the raw water tank 10 can be installed in place. After the installation of the raw water tank 10 is completed, the guide rib 44 is arranged in the guide groove 14, which can improve the connection stability between the raw water tank 10 and the mounting seat 40.

[0053] Combination Figure 3 and Figure 4 In some embodiments of the present invention, a guide groove 14 is provided on the front wall of the raw water tank 10, a positioning groove 13a is provided on the bottom wall of the raw water tank 10 away from the front wall, a guide rib 44 is provided on the inner side of the front side wall of the mounting seat 40, and a positioning protrusion 43 is provided on the bottom of the mounting seat 40 away from the front side wall. The guide groove 14 and the guide rib 44 cooperate with each other, and the positioning groove 13a cooperates with the positioning protrusion 43 to position the installation of the raw water tank 10 in the front-to-back direction, thereby improving the installation efficiency of the raw water tank 10. After the raw water tank 10 is installed, the raw water tank 10 is limited in the front-to-back direction to improve the connection stability of the raw water tank 10, thereby avoiding problems such as water leakage and poor water discharge caused by improper installation of the raw water tank 10.

[0054] Combination Figure 2 and Figure 5 In some embodiments of the present invention, the filter assembly 20 extends in the front-to-back direction, and the filter assembly 20 includes a filter element seat 21 and a filter 22. The filter element seat 21 has a filter element cavity 211, and the filter 22 is removably installed in the filter element cavity 211 in the front-to-back direction. Specifically, the filter element seat 21 can support and fix the filter 22, and the filter assembly 20 extends in the front-to-back direction to optimize the spatial layout of the drinking water purification device 100. In combination with the above, the raw water tank 10 is arranged above the filter assembly 20. By arranging the filter assembly 20 in the front-to-back direction, it is avoided that the filter assembly 20 occupies too much space in the up and down direction, so that the overall structure of the drinking water purification device 100 is more compact, and it is convenient to take and put the raw water tank 10. In addition, the filter 22 is removably installed in the filter element cavity 211 in the front-to-back direction, and the filter 22 is set as a front-drawable structure to facilitate the replacement of the filter 22.

[0055] In some embodiments of the present invention, the filter 22 includes a first filter element 221 and a second filter element 222, one of the first filter element 221 and the second filter element 222 is a pre-post composite filter element, and the other is a reverse osmosis filter element. The first filter element 221 and the second filter element 222 are arranged in the up-down direction, and the filter element cavity 211 has a first cavity 211a and a second cavity 211b arranged in the up-down direction. The first filter element 221 is arranged in the first cavity 211a, and the second filter element 222 is arranged in the second cavity 211b. Specifically, the first filter element 221 and the second filter element 222 are arranged in the up-down direction, and the raw water tank 10 is arranged above the filter 22, so as to reduce the size of the purifying device 100 in the width direction, and facilitate the miniaturization design of the purifying device 100. For example, when the purifying device 100 is placed in the user's kitchen or sideboard, the purifying device 100 can occupy a smaller space, so that the purifying device 100 can adapt to the use scenario of the compact space. In addition, the first filter element 221 and the second filter element 222 both extend in the front-to-back direction, and both the first filter element 221 and the second filter element 222 are front-pull-out structures, making the overall structure of the drinking water purification device 100 more compact.

[0056] Combination Figure 1 and Figure 2 In some embodiments of the present invention, the front end of the filter element cavity 211 is provided with a mounting port 2111 and a cover plate 2112. The cover plate 2112 is provided at the front side of the drinking purification device 100 and is used to open and close the mounting port 2111. For example, when the filter 22 needs to be replaced, the cover plate 2112 can be opened and the filter 22 can be taken out from the mounting port 2111, thereby facilitating the replacement of the filter 22.

[0057] In addition, a filter element socket is provided at the rear end of the filter element cavity 211, and the filter 22 is plugged into and separated from the filter element socket along the front-to-back direction.

[0058] Combination Figure 1 and Figure 2 In some embodiments of the present invention, an installation space 30a is constructed on the lower side of the water purification tank 30, and the installation space 30a is opposite to the filter assembly 20 in the front-to-back direction. Specifically, the filter 22 can be replaced through the installation space 30a. The installation space 30a is located on the front side of the water purification device 100, which can facilitate the user to replace the filter 22 from the front side of the water purification device 100.

[0059] In combination with the above, the filter assembly 20 extends in the front-to-back direction, and the filter 22 is configured as a front-pull-out structure. By providing an installation space 30a at the lower side of the clean water tank 30, the filter element can be easily replaced through the installation space 30a.

[0060] Optionally, a water outlet may be connected to the lower side of the clean water tank 30 , that is, the installation space 30a may be used for taking water at the same time, making the structure of the drinking water equipment more compact, improving the space utilization of the drinking water equipment, and facilitating the replacement of the filter 22 .

[0061] In some embodiments of the present invention, the width dimension of the raw water tank 10 along the left-right direction is greater than or equal to the width dimension of the filter assembly 20 along the left-right direction. It can be understood that the raw water tank 10 contains tap water. After long-term use, the raw water tank 10 may have the precipitation of minerals and impurities.
