[0041] Please refer to Figures 1 to 3 In one embodiment, the drinking water equipment has a cooked water outlet 10 and a boiling water outlet 20. The drinking water equipment 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 pipeline 410 and a cold water pipeline 420 for heat exchange with the hot water pipeline 410. The outlet 411 of the hot water pipeline 410 is connected to the cooked water outlet 10, and the outlet 421 of the cold water pipeline 420 is connected to the inlet 412 of the hot water pipeline 410. The second heating element 300 is arranged between the outlet 421 of the cold water pipeline 420 and the inlet 412 of the hot water pipeline 410; the water circuit component 500 is respectively connected to the water storage component 100, the inlet 422 of the cold water pipeline 420, and the boiling water outlet 20, and the first heating element 200 is arranged between the water storage component 100 and the water circuit component 500.

[0042] Among them, when receiving the boiling water instruction, the pure water output by the water storage component 100 is heated by the first heating element 200 or not heated to boiling, and then output to the boiling water outlet 20 through the water circuit component 500; when receiving the cooked water instruction, the pure water output by the water storage component 100 is heated by the first heating element 200 to not boiling, and then output to the cold water pipe 420 through the water circuit component 500, flows into the second heating element 300 to be heated to boiling, and then enters the hot water pipe 410, so that the boiling water in the hot water pipe 410 and the unboiled water in the cold water pipe 420 are heat exchanged to obtain cooked water, and the cooked water is output to the cooked water outlet 10 through the outlet 411 of the hot water pipe 410.

[0043] It should be noted that the drinking water equipment is the terminal water intake device of the whole-house water purification system, which can switch to different water routes according to different instructions of the user to meet the user's drinking needs.

[0072] For further information, please refer to Fig. 9 and Figure 3The third adapter 700 is fixed to the water storage assembly 100 , the third adapter 700 and the water storage assembly 100 are both located on the bottom side of the heat exchange assembly 400 , and the second adapter 600 and the water channel assembly 500 are both located on the top side of the heat exchange assembly 400 .

[0073] It is understandable that by locating the third adapter 700, the water storage assembly 100 and the second adapter 600, the water channel assembly 500 on opposite sides of the heat exchange assembly 400, respectively, the space utilization can be improved and the overall structure of the drinking water equipment can be made more compact.

[0074] In an embodiment of the present application, the third adapter 700 and the water storage component 100 can be connected in a variety of ways. For example, the third adapter 700 and the water storage component 100 can be detachably connected by screwing, snapping, plugging, etc., which is convenient for timely replacement and maintenance of the components.

[0075] 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 pipeline 420 is constructed as an outer flow channel arranged on the inner wall of the main body 430. The cover plate 440 is covered on the main body 430 to close the outer flow channel. The hot water pipeline 410 is accommodated in the outer flow channel.

[0076] Here, the cover plate 440 is covered on the main body 430, so that a closed outer flow channel can be formed between the cover plate 440 and the main body 430, and the hot water pipe 410 is accommodated in the outer flow channel, which can make the overall structure of the heat exchange assembly 400 more compact.

[0077] In the embodiment of the present application, the main body 430 is a rectangular parallelepiped structure, and accordingly, the cover plate 440 is also rectangular. In other embodiments, the main body 430 can also be cylindrical or other shapes, and accordingly, the cover plate 440 is also circular or other shapes.

[0078] In an embodiment of the present application, the main body 430 and the cover plate 440 are split structures, and the main body 430 and the cover plate 440 can be detachably connected by snap-fitting, screwing, etc., or the main body 430 and the cover plate 440 can be non-detachably connected by welding, riveting, etc.

[0079] Specifically, 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 , and the outlet 421 of the cold water pipe 420 is located on the bottom side of the main body 430 .

[0080] It can be understood that 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 all on the same side, and the inlet 422 of the cold water pipe 420 and the outlet 421 of the cold water pipe 420 are located on different sides, which can extend the path length of the pure water flowing through the cold water pipe 420 as much as possible, thereby ensuring the heat exchange effect between the internal cold water pipes 420.

[0081] In an embodiment of the present application, a first avoidance groove corresponding to the inlet 412 of the hot water pipe 410 and a second avoidance groove corresponding to the outlet 411 of the hot water pipe 410 are opened on the top side of the main body 430, and 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.

[0082] More specifically, please refer to Figures 10 to 12 The hot water pipe 410 is constructed as a bellows structure having at least one tortuous portion.

[0083] Here, by providing at least one tortuous portion, the path length of pure water flowing through the hot water pipeline 410 can be extended as much as possible, thereby ensuring the heat exchange effect between the internal cold water pipelines 420.

[0084] In an embodiment of the present application, the hot water pipeline 410 may be a corrugated tube structure having at least one U-shaped tortuous portion, for example, the hot water pipeline 410 is a continuously tortuous S-shaped corrugated tube.

[0085] 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 arranged at the pure water outlet 112 and is used to prevent the liquid from flowing back to the water tank 110.

[0086] It should be noted that when water replenishment is needed, pure water can be injected into the water tank 110 through the pure water inlet 111 to keep the pure water in the water tank 110 at a normal liquid level. When pure water needs to be supplied, the water pump 120 can pump the pure water in the water tank 110 out from the pure water outlet 112 to the first heating element 200. The setting of the check valve 130 can prevent the pure water in the first heating element 200 from flowing back into the water tank 110, thereby playing a role in preventing dry burning.

[0087] In the embodiments of the present application, the water pump 120 may be a peristaltic pump, a self-priming pump, or other types of pump structures, and the type of the water pump 120 is not limited herein.

[0088] In the embodiment of the present application, the check valve 130 may be a solenoid valve or a mechanical valve, and the type of the check valve 130 is not limited herein.

[0089] For further information, please refer to Figure 1 The water storage assembly 100 also includes a liquid level sensor 140 , which at least partially extends into the water tank 110 and is used to detect the liquid level height in the water tank 110 .

[0090] It is understandable that by real-time monitoring of the liquid level in the water tank 110 , pure water can be supplied or water can be replenished in a timely manner to ensure that the liquid level in the water tank 110 is within a normal range.

[0091] In the embodiment of the present application, the number of the liquid level sensor 140 is not limited to one, and the liquid level sensors 140 can be respectively arranged at different liquid level heights to improve the accuracy of liquid level detection.

[0092] Please refer to Figure 1 and Figure 2 , a control method for a drinking water device in one embodiment comprises the following steps:

[0093] When receiving the boiling water instruction, the pure water outputted by the water storage component 100 is heated to boiling by the first heating element 200 and then outputted to the boiling water outlet 20 through the water channel component 500;

[0094] When receiving the cooked water instruction, the pure water output by the water storage component 100 is heated by the first heating element 200 or not heated to non-boiling state, and then output to the cold water pipe 420 through the water path component 500, flows into the second heating element 300 to be heated to boiling, and then enters the hot water pipe 410, so that the boiling water in the hot water pipe 410 and the unboiled water in the cold water pipe 420 are heat exchanged to obtain cooked water, and the cooked water is output to the cooked water outlet 10 through the outlet 411 of the hot water pipe 410.

[0095] It should be noted that, when receiving the boiling water instruction, 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, and then the boiling water is output to the boiling water outlet 20 through the water channel component 500, and the second heating element 300 does not work at this time;

[0096] When receiving the cooked water instruction, the pure water output by 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 non-boiling temperature (or the first heating element 200 does not operate but allows the pure water to flow), the non-boiling water is output to the cold water pipe 420 through the water path component 500, flows out from the cold water pipe 420 to the second heating element 300, and then enters the hot water pipe 410 after being heated to boiling by the second heating element 300, so that the boiling water in the hot water pipe 410 and the non-boiled water in the cold water pipe 420 are continuously heat exchanged to obtain cooked water, and the cooked water can be output from the outlet 411 of the hot water pipe 410 to the cooked water outlet 10.

[0097] When the above-mentioned drinking water device receives a command to take boiling water, the pure water in the water storage component 100 is heated to boiling by the first heating element 200 and then output, so that boiling water can be quickly obtained; when the command to take cooked water is received, a heat exchange scheme of dual heating elements is adopted, the second heating element 300 heats the pure water to boiling, and the first heating element 200 heats the pure water to a specified temperature, and the boiling water and the unboiled water are exchanged in the heat exchange component 400 to obtain the boiled water (i.e. cooked water) required by the user, and by adjusting the power of the first heating element 200, unboiled water of different temperatures can be obtained, thereby quickly obtaining boiled water of different temperatures, which can better meet the different drinking water needs of users.

[0098] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0099] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
