DETAILED DESCRIPTION

[0027] In order to make the person skilled in the art better understand the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the embodiments of the present application, all other embodiments obtained by the person skilled in the art without creative labor fall within the scope of protection of the embodiments of the present application.

[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0029] Referring to Figure 1 The present application provides a heating drinking water device 100, which comprises a water purification device 200, a water outlet device 300 and a drinking water heating device 100. The drinking water heating device 100 is connected between the water purification device 200 and the water outlet device 300.

[0030] In this way, the drinking water heating device 100 can heat the water treated by the water purification device 200, and the heated water can be taken by a user through the water outlet device 300, such as a water faucet, thereby meeting the user's demand for taking hot water.

[0031] Referring to Figure 2 and Figure 3 In some embodiments, the drinking water heating device 100 comprises a mounting shell 11, a first heating assembly 12 and a second heating assembly 13. The mounting shell 11 is provided with a first accommodating cavity 113 and a second accommodating cavity 114, and the first accommodating cavity 113 is communicated with the second accommodating cavity 114. The first heating assembly 12 is mounted in the first accommodating cavity 113, and the second heating assembly 13 is mounted in the second accommodating cavity 114. The second heating assembly 13 is communicated with the first heating assembly 12, and the second heating assembly 13 is adapted to heat the liquid heated by the first heating assembly 12.

[0032] In this way, the drinking water heating device 100 can preheat the water through the first heating assembly 12, and then heat the preheated water through the second heating assembly 13, so that the water can be in a suitable temperature environment, and the water heated by the first heating assembly 12 can be warmed before entering the second heating assembly 13, which helps to increase the kinetic energy of the water, helps to increase the water inlet rate of the second heating assembly 13, helps to increase the water outlet rate of the second heating assembly 13, and helps to increase the hot water outlet rate of the drinking water heating device 100.

[0033] Exemplarily, water can enter the first heating assembly 12 for heating, and the water heated to a certain temperature in the first heating element 123 flows out of the first heating assembly 12, for example, the water heated to 60-80℃ flows out of the first heating assembly 12, so that the water is warmed before entering the second heating assembly 13, thereby increasing the kinetic energy of the water, which helps to increase the flow rate of the water at the inlet of the second heating assembly 13 and thus the rate of water entering the second heating assembly 13. The water heated by the first heating assembly 12 enters the second heating element 131 for heating, and the water heated by the second heating assembly 13 can be warmed to 90-98℃, at which time the temperature of the water is increased, which helps to increase the flow rate of the water at the outlet of the second heating assembly 13 and thus the rate of hot water out of the second heating assembly 13, thereby increasing the rate of hot water out of the water heating device 100. Finally, the heated hot water is discharged from the water outlet device 300 for the user to use.

[0034] In some embodiments, the water outlet rate of the water heating device 100 can reach 1 L / min, which can be set according to actual conditions.

The first heating element 123 is adapted to heat the liquid in the mounting cavity 1211, and the coil 122 is adapted to exchange heat with the liquid in the mounting cavity 1211.

[0036] In this way, water can enter the coil 122 to exchange heat with the heated liquid in the mounting cavity 1211 to meet the heat exchange requirements of the water in the coil 122. The first heating assembly 12 has a simple structure and is easy to manufacture.

[0037] Exemplarily, the coil 122 can be provided with a coil inlet 1221 and a coil outlet 1222. When the first heating assembly 12 is working, the water treated by the water purifying device 200 can enter the coil 122 from the coil inlet 1221 to exchange heat with the heated liquid in the mounting cavity 1211, and the heat-exchanged water can be discharged from the coil 122 through the coil outlet 1222, thereby realizing the heating of water by the first heating assembly 12.

[0038] In some embodiments, the first heating assembly 12 can also be provided with a water supplement port 125, which is communicated with the mounting cavity 1211. The first heating assembly 12 can supplement water into the mounting cavity 1211 through the water supplement port 125, which helps to ensure that there is enough water in the mounting cavity 1211 for heat exchange, thereby helping to ensure the normal work of the first heating assembly 12.

[0039] In some embodiments, the first heating assembly 12 further comprises a temperature controller 124, the temperature controller 124 is attached to the surface of the first heating element 123 away from the coil 122.

[0040] In this way, the temperature controller 124 can directly detect the temperature of the first heating element 123, when the first heating element 123 is dry-burned without water, the temperature controller 124 can detect the change of the temperature of the first heating element 123 and respond quickly, which helps to reduce the damage of the dry-burning of the first heating element 123, and also helps to reduce the influence of the temperature of the coil 122 on the temperature controller 124, and helps to improve the accuracy of the temperature controller 124 in detecting the temperature of the first heating element 123.

In addition, the second heating assembly 13 does not need to separately set up a pipeline to connect the second heating element 131 and the solenoid valve 132, which helps to simplify the structure of the second heating assembly 13 and facilitate manufacturing. The solenoid valve 132 is inserted into the solenoid valve interface 1311, which helps to improve the compactness of the structure of the second heating assembly 13, and also helps to simplify the way the solenoid valve 132 is connected to the second heating element 131, and facilitates the assembly of the solenoid valve 132 and the second heating element 131.

[0044] Because the water circuit board assembly 14 adopts a modular structure design, the water circuit in and out of the water heating device 100 is orderly, which helps to improve the stability of the water circuit operation in the water heating device 100. The water heating device 100 can connect other devices through the water circuit board assembly 14 to ensure the normal flow of the water circuit, and the water heating device 100 does not need to set up multiple pipelines to connect the second heating assembly 13 and other devices, which helps to simplify the structure of the second heating assembly 13 and facilitate manufacturing.

[0045] In addition, the water outlet 133 is plugged into the water inlet 141, which helps to improve the compactness of the second heating assembly 13 and the waterway plate assembly 14, and also helps to simplify the connection mode of the second heating assembly 13 and the waterway plate assembly 14, and facilitates the assembly of the second heating assembly 13 and the waterway plate.

[0046] In some embodiments, the water heating device 100 can further include an electric control assembly 15 located in the second accommodating cavity 114 and electrically connected to the first heating assembly 12, the second heating assembly 13, and the waterway plate assembly 14.
