Description

Technical Field

[0001] This application relates to the field of water purification technology, and in particular to a drinking water device. Background Technology

[0002] Currently, water dispensers are the end-point water intake devices in whole-house water purification systems. They are generally installed after the water purifier and use built-in heating or cooling devices to adjust the temperature of the purified water dispensed by the water purifier to meet the user's drinking needs.

[0003] Most existing water dispensers use instant heating, which directly heats room temperature water to the set temperature before providing it to users, without heating it to boiling. If users want to drink cold boiled water, they have to boil the water and then wait for it to cool down, which takes a long time. Utility Model Content

[0004] Therefore, it is necessary to provide a drinking water device to address the problem that the water dispensed by existing pipeline machines is not heated to boiling.

[0039] Please refer to Figures 1 to 3In one embodiment, the drinking water device has a boiled water outlet 10 and a hot water outlet 20. The drinking water device includes a water storage component 100, a first heating element 200, a second heating element 300, a heat exchange component 400, and a water circuit component 500. The heat exchange component 400 has a hot water pipe 410 and a cold water pipe 420 that exchanges heat with the hot water pipe 410. The outlet 411 of the hot water pipe 410 is connected to the boiled water outlet 10, and the outlet 421 of the cold water pipe 420 is connected to the inlet 412 of the hot water pipe 410. The second heating element 300 is disposed between the outlet 421 of the cold water pipe 420 and the inlet 412 of the hot water pipe 410. The water circuit component 500 is connected to the water storage component 100, the inlet 422 of the cold water pipe 420, and the hot water outlet 20, respectively. The first heating element 200 is disposed between the water storage component 100 and the water circuit component 500.

[0040] When a boiling water command is received, the pure water output from the water storage component 100 is heated to boiling (or not heated) by the first heating element 200 and then output to the boiling water outlet 20 via the water circuit component 500. When a cooked water command is received, the pure water output from the water storage component 100 is heated to a non-boiling state by the first heating element 200 and then output to the cold water pipeline 420 via the water circuit component 500. After flowing into the second heating element 300 and being heated to boiling, the water enters the hot water pipeline 410, where the boiling water in the hot water pipeline 410 exchanges heat with the non-boiling water in the cold water pipeline 420 to obtain cooked water. The cooked water is then output to the cooked water outlet 10 via the outlet 411 of the hot water pipeline 410.

[0041] It should be noted that the drinking water equipment is the end-point water intake device of the whole-house water purification system, which can switch to different water circuits according to different user instructions to meet the user's drinking needs.

[0042] For example, when receiving a command to fetch boiling water, refer to Figure 1 and Figure 2 Pure water in the water storage component 100 is input into the first heating element 200. The first heating element 200 operates at full power and heats the pure water to boiling. Then the boiling water is output to the boiling water outlet 20 through the water circuit component 500. At this time, the second heating element 300 does not work.

[0043] Upon receiving a request to retrieve boiled water, refer to Figure 1 and Figure 2The pure water output from the water storage component 100 is input into the first heating element 200. The first heating element 200 operates at low power and heats the pure water to a temperature before boiling (or the first heating element 200 does not operate but only allows the pure water to circulate). The unboiled water is output through the water circuit component 500 to the cold water pipe 420, and then flows out of the cold water pipe 420 to the second heating element 300. After being heated to boiling by the second heating element 300, it enters the hot water pipe 410. In this way, the boiling water in the hot water pipe 410 and the unboiled water in the cold water pipe 420 continuously exchange heat to obtain cooked water. The cooked water can be output from the outlet 411 of the hot water pipe 410 to the cooked water outlet 10.

[0044] The aforementioned drinking water device, upon receiving a command to obtain boiling water, heats the pure water in the water storage component 100 to boiling point using the first heating element 200, and then outputs the boiling water, thus quickly obtaining boiling water. Upon receiving a command to obtain cooked water, a dual-heating element heat exchange scheme is adopted. The second heating element 300 heats the pure water to boiling point, while the first heating element 200 heats the pure water to a specified temperature. The boiling water and the unboiled water exchange heat within the heat exchange component 400 to obtain the user's desired cooled boiled water (i.e., cooked water). Furthermore, by adjusting the power of the first heating element 200, unboiled water at different temperatures can be obtained, thus quickly obtaining cooled boiled water at different temperatures, which can better meet the user's different drinking water needs.

[0045] In the embodiments of this application, the above-mentioned drinking water device further includes a controller, which is electrically connected to the water storage component 100, the first heating element 200, the second heating element 300, the heat exchange component 400 and the water circuit component 500 respectively. The controller can control the above components to operate in the corresponding state according to the user's instructions.

[0046] In the embodiments of this application, both the first heating element 200 and the second heating element 300 are heating elements, that is, they are capable of generating heat. The heating element can be a heating wire, an infrared heating tube, or other types of heating structure. The number of the first heating element 200 and the second heating element 300 is not limited to one; that is, the number of the first heating element 200 and the second heating element 300 can be at least two.

[0047] In the embodiments of this application, the heat exchange assembly 400 has a hot water pipe 410 and a cold water pipe 420. The cold water pipe 420 surrounds the hot water pipe 410, and a flow gap is formed between the inner wall of the cold water pipe 420 and the outer wall of the hot water pipe 410, so that water can enter the flow gap from the inlet 422 of the cold water pipe 420 and flow out from the outlet 421 of the cold water pipe 420. The hot water pipe 410 and the cold water pipe 420 are conformally fitted, meaning that the shapes of the hot water pipe 410 and the cold water pipe 420 are adapted to each other.

[0048] Please refer to Figure 3The water circuit assembly 500 includes a first adapter 510, a control valve 520, and a water circuit plate 530. A first heating element 200 is located between the water storage assembly 100 and the first adapter 510. A control valve 520 is located between the first adapter 510 and the water circuit plate 530. The water circuit plate 530 is connected to the heat exchange assembly 400, and both the boiled water outlet 10 and the boiling water outlet 20 are located on the water circuit plate 530.

[0049] It should be noted that, along the flow direction of pure water, the first heating element 200, the first adapter 510, the control valve 520, the water circuit board 530, and the heat exchange component 400 are arranged in sequence so that each component can switch to the corresponding state according to the user's instructions, thereby switching to different water flow paths.

[0050] In the embodiments of this application, the first adapter 510, the control valve 520, and the water circuit board 530 can be an integrated structure, that is, the three are integrated into a single structure, which has good integrity and is easy to assemble and disassemble quickly. In other embodiments, the first adapter 510, the control valve 520, and the water circuit board 530 can also be separate structures, and the three can be fixed together by snap-fit, screw connection, or other methods.

[0051] In the embodiments of this application, the control valve 520 is a solenoid valve, which enables automatic control. In other embodiments, the control valve 520 may also be other types of mechanical valves.

[0052] In the embodiments of this application, the water circuit board 530 is a component with multiple interfaces or outlets, through which water can flow between the control valve 520 and the heat exchange assembly 400.

[0053] For details, please refer to Figure 4 and Figure 5 The water storage component 100 has a first heating inlet 101, and the first adapter 510 has a first heating outlet 511. The first heating inlet 101 is connected to the inlet of the first heating element 200, and the first heating outlet 511 is connected to the outlet of the first heating element 200.

[0054] Here, the pure water in the water storage component 100 can enter the first heating element 200 through the first heating inlet 101 and the inlet of the first heating element 200, and after being heated by the first heating element 200, it can be output through the outlet of the first heating element 200 and the first heating outlet 511.

[0055] In the embodiments of this application, the first heating inlet 101 is inserted into the inlet of the first heating element 200. A sealing sleeve may also be added between the first heating inlet 101 and the inlet of the first heating element 200 to ensure good sealing at the insertion point. Optionally, the number of the first heating inlet 101 and the inlet of the first heating element 200 is not limited to one, and the first heating inlet 101 and the inlet of the first heating element 200 are provided in a one-to-one correspondence.

[0056] In the embodiments of this application, the first heating outlet 511 is inserted into the outlet of the first heating element 200. A sealing sleeve may also be added between the first heating outlet 511 and the outlet of the first heating element 200 to ensure good sealing at the insertion point. Optionally, the number of the first heating outlet 511 and the outlet of the first heating element 200 is not limited to one, and the first heating outlet 511 and the outlet of the first heating element 200 are arranged in a one-to-one correspondence.

[0057] For more specific details, please refer to Figure 6 The water circuit board 530 has a boiling water inlet 531, a non-boiling water inlet 532, and an external inlet 533. The first adapter 510 also has a valve port 512. The control valve 520 has a first interface 521, a second interface 522, and a third interface 523. The first interface 521 is connected to the valve port 512. The second interface 522 is connected to the inlet 422 of the cold water pipeline 420 through the non-boiling water inlet 532 and the external inlet 533. The third interface 523 is connected to the boiling water outlet 20 through the boiling water inlet 531. When a boiling water command is received, the first interface 521 and the third interface 523 are opened, and the second interface 522 is closed. When a boiled water command is received, the first interface 521 and the second interface 522 are opened, and the third interface 523 is closed.

[0058] Understandably, upon receiving a boiling water command, the pure water in the water storage component 100 is heated to boiling by the first heating element 200 and then sequentially output to the boiling water outlet 20 via the first heating outlet 511, valve 512, first interface 521, third interface 523, and boiling water inlet 531.

[0059] Upon receiving a command to obtain boiled water, the pure water in the water storage component 100 is heated to a non-boiling state by the first heating element 200, and then flows sequentially through the first heating outlet 511, valve port 512, first interface 521, second interface 522, non-boiling water inlet 532, external inlet 533, and inlet 422 of the input cold water pipeline 420. It then flows out from the outlet 421 of the cold water pipeline 420 into the second heating element 300, and is then heated to boiling state by the second heating element 300. After boiling, it enters the hot water pipeline 410 through the inlet 412. In this way, the boiling water in the hot water pipeline 410 and the non-boiling water in the cold water pipeline 420 continuously exchange heat to obtain boiled water, which can be output from the outlet 411 of the hot water pipeline 410 to the boiled water outlet 10.

[0060] In the embodiments of this application, the boiling water inlet 531, the non-boiling water inlet 532, and the external inlet 533 can be located on the same side of the water circuit board 530 or on different sides of the water circuit board 530, and the position of each interface can be adjusted according to actual needs.

[0061] In the embodiments of this application, the control valve 520 is a solenoid valve with one inlet and two outlets, capable of automatic water circuit switching. In other embodiments, the control valve 520 may also be a four-way valve or other types of valves.

[0062] Please refer to Figures 7 to 9 The drinking water equipment also includes a second adapter 600 and a third adapter 700. The third adapter 700 has a second heating inlet 701, and the second adapter 600 has a second heating outlet 601. The second heating outlet 601 is connected to the outlet of the second heating element 300, and the second heating inlet 701 is connected to the inlet of the second heating element 300.

[0063] It should be noted that the pure water in the water storage component 100 can enter the second heating element 300 through the second heating inlet 701 and the inlet of the second heating element 300, and after being heated by the second heating element 300, it can be output through the outlet of the second heating element 300 and the second heating outlet 601.

[0064] In the embodiments of this application, the second heating inlet 701 is inserted into the inlet of the second heating element 300. A sealing sleeve may also be added between the second heating inlet 701 and the inlet of the second heating element 300 to ensure good sealing at the insertion point. Optionally, the number of the second heating inlet 701 and the inlet of the second heating element 300 is not limited to one, and the second heating inlet 701 and the inlet of the second heating element 300 are provided in a one-to-one correspondence.

[0065] In the embodiments of this application, the second heating outlet 601 is inserted into the outlet of the second heating element 300. A sealing sleeve may also be added between the second heating outlet 601 and the outlet of the second heating element 300 to ensure good sealing at the insertion point. Optionally, the number of the second heating outlet 601 and the outlet of the second heating element 300 is not limited to one, and the second heating outlet 601 and the outlet of the second heating element 300 are arranged in a one-to-one correspondence.

[0066] Further, please refer to Figure 8 and Figure 9 The third adapter 700 also has an external outlet 702, the second adapter 600 also has an internal inlet 602, the water circuit board 530 also has an internal outlet 534, the internal outlet 534 is connected to the outlet 411 of the hot water pipe 410, the internal inlet 602 is connected to the inlet 412 of the hot water pipe 410, and the external outlet is connected to the outlet 421 of the cold water pipe 420.

[0067] It should be noted that the external inlet 533 of the water circuit board 530, the inlet 422 of the cold water pipe 420, the outlet 421 of the cold water pipe 420, the external outlet of the third adapter 700, the internal inlet 602 of the second adapter 600, the inlet 412 of the hot water pipe 410, the outlet 411 of the hot water pipe 410, the internal outlet 534 of the water circuit board 530, and the boiled water outlet 10 are connected in sequence.

[0068] Here, upon receiving a command to obtain boiled water, the pure water in the water storage component 100 is heated to a non-boiling state by the first heating element 200, and then flows sequentially through the first heating outlet 511, valve port 512, first interface 521, second interface 522, non-boiling water inlet 532, external inlet 533, and inlet 422 of the input cold water pipeline 420. It then flows out from the outlet 421 of the cold water pipeline 420 through the external outlet and into the second heating element 300. After being heated to boiling by the second heating element 300, it enters the hot water pipeline 410 through the internal inlet 602 and the inlet 412 of the hot water pipeline 410. Thus, the boiling water in the hot water pipeline 410 and the non-boiling water in the cold water pipeline 420 continuously exchange heat to obtain boiled water, which can be output from the outlet 411 of the hot water pipeline 410 and the internal outlet 534 to the boiled water outlet 10.

[0069] In the embodiments of this application, the second adapter 600 and the third adapter 700 are both physical connectors, and the second adapter 600 and the third adapter 700 are used to achieve connectivity or compatibility between different interfaces.

[0070] Furthermore, please refer to Figure 9 and Figure 3The third adapter 700 is fixed to the water storage component 100. Both the third adapter 700 and the water storage component 100 are located on the bottom side of the heat exchange component 400, while the second adapter 600 and the water circuit component 500 are located on the top side of the heat exchange component 400.

[0071] It is understandable that by placing the third adapter 700, the water storage component 100, the second adapter 600, and the water circuit component 500 on opposite sides of the heat exchange component 400, space utilization can be improved and the overall structure of the drinking water equipment can be made more compact.

[0072] In the embodiments of this application, the third adapter 700 and the water storage component 100 can be connected in various ways. For example, the third adapter 700 and the water storage component 100 can be detachably connected by screwing, snapping, plugging, etc., which facilitates timely replacement and maintenance of the components.

[0073] Please refer to Figures 10 to 12 The heat exchange assembly 400 includes a main body 430 and a cover plate 440. The cold water pipe 420 is configured as an external flow channel located on the inner wall of the main body 430. The cover plate 440 covers the main body 430 to close the external flow channel. The hot water pipe 410 is housed in the external flow channel.

[0074] Here, the cover plate 440 is placed on the main body 430, which can form a closed external flow channel between the cover plate 440 and the main body 430. The hot water pipe 410 is housed in the external flow channel, which can make the overall structure of the heat exchange component 400 more compact.

[0075] In the embodiments of this application, the main body 430 has a cuboid structure, and correspondingly, the cover plate 440 is also rectangular. In other embodiments, the main body 430 may also be cylindrical or other shapes, and correspondingly, the cover plate 440 may also be circular or other shapes.

[0076] In the embodiments of this application, the main body 430 and the cover plate 440 are separate structures. The main body 430 and the cover plate 440 can be detachably connected by means of snap-fit, screw connection or other means, or the main body 430 and the cover plate 440 can also be non-detachably connected by means of welding, riveting or other means.

[0077] For details, please refer to Figures 10 to 12 The inlet 412 of the hot water pipe 410, the outlet 411 of the hot water pipe 410, and the inlet 422 of the cold water pipe 420 are located on the top side of the main body 430, while the outlet 421 of the cold water pipe 420 is located on the bottom side of the main body 430.

[0078] It is understandable that the inlet 412 and outlet 411 of the hot water pipe 410 and the inlet 422 of the cold water pipe 420 are all on the same side, while the inlet 422 and outlet 421 of the cold water pipe 420 are located on different sides. This can maximize the path length of pure water flowing through the cold water pipe 420, thereby ensuring the heat exchange effect between the inner cold water pipes 420.

[0079] In the embodiments of this application, the top side of the main body 430 is provided with a first clearance groove corresponding to the inlet 412 of the hot water pipe 410 and a second clearance groove corresponding to the outlet 411 of the hot water pipe 410. The inlet 422 of the cold water pipe 420 is directly opened on the top side of the main body 430, and the outlet 421 of the cold water pipe 420 is directly opened on the bottom side of the main body 430.

[0080] For more specific details, please refer to Figures 10 to 12 The hot water pipe 410 is constructed as a corrugated pipe structure with at least one bend.

[0081] Here, by setting at least one bend, the path length of pure water flowing through the hot water pipe 410 can be extended as much as possible, thereby ensuring the heat exchange effect between the internal cold water pipes 420.

[0082] In the embodiments of this application, the hot water pipe 410 can be a corrugated pipe structure with at least one U-shaped bend, for example, the hot water pipe 410 is a continuously tortuous S-shaped corrugated pipe.

[0083] Please refer to Figure 3 The water storage assembly 100 includes a water tank 110, a water pump 120, and a check valve 130. The water tank 110 has a pure water inlet 111 and a pure water outlet 112. The water pump 120 is connected to the pure water outlet 112 and is used to provide power. The check valve 130 is located at the pure water outlet 112 and is used to prevent liquid from flowing back into the water tank 110.

[0084] It should be noted that when water needs to be replenished, pure water can be injected into the water tank 110 through the pure water inlet 111 to maintain the pure water level in the water tank 110 at the normal level. When pure water needs to be supplied, the water pump 120 can draw the pure water in the water tank 110 out of the pure water outlet 112 to the first heating element 200. The check valve 130 is provided to prevent the pure water in the first heating element 200 from flowing back into the water tank 110, thus providing anti-dry burning protection.

[0085] In the embodiments of this application, the water pump 120 can be a peristaltic pump, a self-priming pump, or other types of pump body structure, and the type of water pump 120 is not limited here.

[0086] In the embodiments of this application, the check valve 130 can be a solenoid valve or a mechanical valve, and the type of check valve 130 is not limited here.

[0087] Further, please refer to Figure 1 The water storage assembly 100 also includes a level sensor 140, which extends at least partially into the water tank 110 and is used to detect the liquid level in the water tank 110.

[0088] Understandably, by monitoring the liquid level in the water tank 110 in real time, pure water can be supplied or replenished in a timely manner to ensure that the liquid level in the water tank 110 is within the normal range.

[0089] In the embodiments of this application, the number of liquid level sensors 140 is not limited to one. Liquid level sensors 140 can be set at different liquid level heights to improve the accuracy of liquid level detection.

[0090] Please refer to Figure 1 and Figure 2 One embodiment of the control method for the drinking water device includes the following steps:

[0091] Upon receiving a boiling water command, the pure water output from the water storage component 100 is heated to boiling by the first heating element 200 and then output to the boiling water outlet 20 via the water circuit component 500.

[0092] Upon receiving a command to obtain boiled water, the pure water output from the water storage component 100 is heated by the first heating element 200 or not heated to a state of non-boiling, and then output to the cold water pipeline 420 via the water circuit component 500. After flowing into the second heating element 300 and being heated to boiling, it enters the hot water pipeline 410, where the boiling water in the hot water pipeline 410 exchanges heat with the non-boiling water in the cold water pipeline 420 to obtain boiled water. The boiled water is then output to the boiled water outlet 10 via the outlet 411 of the hot water pipeline 410.

[0093] It should be noted that when a boiling water command is received, the pure water in the water storage component 100 is input into the first heating element 200. The first heating element 200 operates at full power and heats the pure water to boiling. Then the boiling water is output to the boiling water outlet 20 through the water circuit component 500. At this time, the second heating element 300 does not work.

[0094] Upon receiving a command to obtain boiled water, the pure water output from the water storage component 100 is input into the first heating element 200. The first heating element 200 operates at low power and heats the pure water to a temperature before boiling (or the first heating element 200 does not operate but simply allows the pure water to circulate). The unboiled water is output through the water circuit component 500 to the cold water pipe 420, and then flows out of the cold water pipe 420 to the second heating element 300. After being heated to boiling by the second heating element 300, it enters the hot water pipe 410. In this way, the boiling water in the hot water pipe 410 and the unboiled water in the cold water pipe 420 continuously exchange heat to obtain boiled water. The boiled water can be output from the outlet 411 of the hot water pipe 410 to the boiled water outlet 10.

[0095] The aforementioned drinking water device, upon receiving a command to obtain boiling water, heats the pure water in the water storage component 100 to boiling point using the first heating element 200, and then outputs the boiling water, thus quickly obtaining boiling water. Upon receiving a command to obtain cooked water, a dual-heating element heat exchange scheme is adopted. The second heating element 300 heats the pure water to boiling point, while the first heating element 200 heats the pure water to a specified temperature. The boiling water and the unboiled water exchange heat within the heat exchange component 400 to obtain the user's desired cooled boiled water (i.e., cooked water). Furthermore, by adjusting the power of the first heating element 200, unboiled water at different temperatures can be obtained, thus quickly obtaining cooled boiled water at different temperatures, which can better meet the user's different drinking water needs.

[0096] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0097] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
