[0039] 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 only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] The instant heating system of a water purifier according to a first embodiment of the present invention will be described below with reference to the accompanying drawings.

[0041] like Figure 1-Figure 6 As shown, the instant heating system of the water purifier according to the embodiment of the present invention includes: a clean water tank 500, a heating element 320, a water pump 330 and an electric control board 340.

[0042] Specifically, the water inlet of the water pump 330 is connected to the clean water tank 500. The heating element 320 has a heating chamber 321, and the heating chamber 321 has an inlet 322 and an outlet 323, and the inlet 322 is connected to the water outlet of the water pump 330. For example, the heating element 320 can be a heating tube. The electric control board 340 communicates with the water pump 330 and the heating element 320 respectively. It can be understood that the "communication" here includes the two situations that the heating element 320 and the water pump 330 are respectively connected to the electric control board 340 by wire and wirelessly, and the present invention does not make any special limitation on this.

[0043] The electric control board 340 controls the heating element 320 to switch between a first state of emptying the heating chamber 321 and a second state of filling the heating chamber 321 with water. That is, when the heating element 320 is in the first state, the water in the heating chamber 321 and the water path downstream of the outlet 323 is discharged toward the water path upstream of the inlet 322, where the upstream and downstream are relative to the water filling state; when the heating element 320 is in the second state, the water pump 330 pumps the water in the clean water tank 500 into the heating chamber 321. In this way, the heating element 320 can be heated during the time when the water flows into the heating chamber 321.

[0044] Therefore, according to the instant heating system of the water purifier according to the embodiment of the present invention, the heating chamber 321 is emptied before each heating, and there is no water downstream of the water outlet of the heating element 320. In this way, during each heating, water is first pumped into the heating chamber 321 by the water pump 330 for heating, and then flows out after being heated by the heating element 320, thereby ensuring the outlet water temperature and minimizing the amount of unheated water when the water is just discharged.

[0045] Specifically, the present invention uses the design of the flow channel to ensure that the water to be heated is always at the front end of the water inlet of the heating element 320 (i.e., upstream of the water outlet), and there is no water in the heating chamber 321. In other words, before the water is discharged, there is no water in the heating element 320 and between the heating element 320 and the water intake point, and no unheated water will flow out. In this way, all the water is heat-exchanged through the heating element 320 each time it is heated, thereby ensuring the outlet water temperature.

[0046] According to some embodiments of the present invention, Figure 3 and Figure 4 As shown, the clean water tank 500 is located below the heating element 320, and the water in the heating chamber 321 flows back out of the inlet 322 under the action of its own gravity to switch the heating element 320 from the second state to the first state. For example, the water pump 330 does not seal the water, that is, the water pump 330 is configured to allow water to flow naturally when it stops working, so that after the heating is completed, the water pump 330 stops working, and the water in the heating chamber 321 can flow back into the clean water tank 500 under the action of gravity; during heating, the water pump 330 works, and water is pumped from the clean water tank 500 to the heating chamber 321.

[0047] Alternatively, if Figure 3 As shown, the outlet 323 is located above the inlet 322, so as to facilitate smooth return of water after heating is completed.

[0048] According to some embodiments of the present invention, the electric control board 340 switches the heating element 320 to the first state by controlling the water pump 330 to rotate in the direction opposite to the direction in which water enters the heating chamber 321. That is, the electric control board 340 controls the water pump 330 to reverse and realizes the reflux of water in the heating chamber 321. For example, when water enters the heating chamber 321, the water pump 330 rotates in the first direction; when the heating chamber 321 is emptied, the water pump 330 rotates in the second direction, and the first direction is opposite to the second direction. In this way, it can be ensured that there is no water in the heating chamber 321, and sufficient heating is guaranteed for the next time.

[0049] Furthermore, the water pump 330 is configured to disconnect the water path when it stops working, that is, the water pump 330 seals the water. When the water pump 330 stops working, water cannot flow naturally under the action of gravity to ensure control reliability.

[0050] According to some embodiments of the present invention, Figure 3 and Figure 4 As shown, the water pump 330 is located below the heating element 320 , thereby preventing the water pump 330 from being affected by high temperature.

[0051] According to some embodiments of the present invention, the surface of the heating element 320 may be provided with a first detection device for detecting the temperature of the heating element 320, and the first detection device communicates with the electric control board 340. For example, the first detection device is a temperature sensor, so that the instant heating system can be protected to prevent the danger caused by the excessive temperature of the heating element 320 due to damage to the water pump 330 or poor water supply, that is, it can protect the operation of the components and sensors when taking water during the use of the water purifier, and also avoid the false alarm of over-temperature caused by the fact that there is no water in the heating element 320 when the water pump 330 is just started.

[0052] In some specific embodiments of the present invention, the electric control board 340 includes: a low-pressure control module 341 and a high-pressure control module 342. The low-pressure control module 341 communicates with the water pump 330, and the high-pressure control module 342 communicates with the heating element 320. In this way, the electric control board 340 controls the rotation speed of the water pump 330 through the low-pressure control module 341, thereby forming different flow rates; and controls the heating power of the heating element 320 through the high-pressure control module 342, thereby forming different temperature rise conditions.

[0053] like Figure 1-Figure 6 As shown, the water purifier 10 according to the second embodiment of the present invention comprises: a housing 100, a water purification system, the instant heating system of the water purifier according to the first embodiment of the present invention, and a raw water tank 400.

[0054] Specifically, the housing 100 has a water outlet 11. The water purification system is arranged in the housing 100, and the water purification system includes a filter element assembly 220, a booster pump and a flushing valve 230. For example, the flushing valve 230 can be a solenoid valve for controlling the amount of wastewater discharged from the filter element assembly 220. The instant heating system is arranged in the housing 100 and the outlet 323 is connected to the water outlet 11. As the water source of the water purifier 10, the raw water tank 400 can be a movable water tank, and the user can remove the water, and the clean water tank 500 is used to accommodate the water purified by the filter element assembly 220. The booster pump is connected to the raw water tank 400 and the filter element assembly 220 respectively, the filter element assembly 220 is connected to the flushing valve 230 and the clean water tank 500 respectively, and the booster pump and the flushing valve 230 communicate with the electric control board 340 respectively.

[0055] It can be understood that the "communication" here includes the two situations that the booster pump, flushing valve 230, heating element 320 and water pump 330 are respectively connected to the electric control board 340 by wire and by wireless, and the present invention does not make any special limitation on this.

[0056] The water purifier 10 according to the embodiment of the present invention can produce hot water instantly by using the instant heating system of the water purifier as described above.

[0057] The desktop water purifier in the related art has many functions, complex internal structure and components, and contains mixed water and electricity, which has a great impact on the safety, performance, convenience and maintainability of the water purifier.

[0058] According to some embodiments of the present invention, Figure 3-Figure 6 As shown, the water purification system further includes a water purification base 210, on which a filter element assembly 220, a booster pump and a flushing valve 230 are mounted. The instant heating system further includes a heating base 310, on which a heating element 320 and an electric control board 340 are mounted, and an installation space defined by the heating base 310 is independent of an installation space defined by the water purification base 210.

[0059] Here, the installation spaces being independent of each other means that the installation of the water purification system and the installation of the heating system do not interfere with each other. For example, when the heating base 310 and the water purification base 210 are an integral part, the water purification system and the heating system are installed on different surfaces (such as the front and the back); when the heating base 310 and the water purification base 210 are separate parts, the water purification system and the heating system do not interfere with each other at all.

[0060] In this way, the main parts and components for realizing the water purification function, such as the filter element assembly 220, the booster pump and the flushing valve 230, are assembled together to form the water purification module 200; the main parts and components for realizing the heating function, such as the heating element 320 and the electric control board 340, are assembled together to form the heating module 300. The water in the raw water tank 400 is purified by the water purification module 200 and stored in the clean water tank 500. The water in the clean water tank 500 is pumped out by the pump 330 on the heating module 300, and the water is discharged after being heated by the heating element 320. The overall internal control logic and power supply are controlled by the electric control board 340.

[0061] According to the water purifier 10 of the embodiment of the present invention, the filter element assembly 220, the booster pump and the flushing valve 230 are uniformly arranged on the water purification base 210, and the heating element 320 and the electric control board 340 are uniformly arranged on the heating base 310. The functional areas of the whole machine are separated (that is, the water purification system and the instant heating system are arranged separately), the performance is guaranteed, and the assembly and maintenance are relatively simple; in addition, such a modular design realizes the separation of water and electricity, and is safe to use.

[0062] According to some embodiments of the present invention, Figure 2 As shown, the raw water tank 400 is arranged outside the housing 100, and the clean water tank 500 is arranged inside the housing 100. Figure 3As shown, the clean water tank 500 is located below the raw water tank 400. In this way, it is beneficial to separate water from electricity and ensure safety.

[0063] Optionally, the water purifier 10 further includes a waste water tank, which is arranged side by side with the raw water tank 400, for example, the waste water tank and the raw water tank 400 share a side wall. A raw water interface and a waste water interface are provided on the top of the clean water tank 500, the raw water interface is connected to the raw water tank 400, and the waste water interface is connected to the waste water tank 600. In this way, the structure is relatively compact and the assembly is relatively convenient.

[0064] Furthermore, if Figure 3 and Figure 4 As shown, the clean water tank 500 is located below the electric control panel 340, that is, the electrical components are on the top and the clean water tank 500 is on the bottom, thereby preventing water from reaching the electrical components when leaking, thereby enhancing safety.

[0065] According to some embodiments of the present invention, Figure 3 As shown, the water purification base 210 is arranged adjacent to the heating base 310, and the water purification base 210 and the heating base 310 are both located in front of the raw water tank 400. For example, the water purification module 200 and the heating module 300 are arranged side by side, the water purification module 200 is located on the left side of the heating module 300, the raw water tank 400 and the water purification tank 500 are both located at the rear of the water purification module 200 and the heating module 300, and the control panel 101 is provided in front of the water purification module 200 and the heating module 300, and the water outlet 11 is located below the control panel 101, so that the arrangement logic conforms to the ergonomic design, further improving the convenience of use.

[0066] Among them, the water purification base 210 and the heating base 310 can be connected together by fasteners such as screws, and the water purification base 210 and the heating base 310 can be connected to the clean water tank 500 respectively by fasteners such as screws, so that the structure is relatively reliable.

[0067] According to some embodiments of the present invention, Figure 3 and Figure 4 As shown, the heating element 320, the water pump 330 and the electric control board 340 are installed on the surface of the heating base 310 facing away from the water purification base 210. For example, the water purification module 200 and the heating module 300 are arranged side by side, the water purification module 200 is located on the left side of the heating module 300, the heating base 310 is placed facing the right side, and the heating element 320, the water pump 330 and the electric control board 340 are installed on the right side surface of the heating base 310, so that the heating base 310 can play the role of separating the heating element 320, the water pump 330 and the electric control board 340 from the water purification module 200, and it is also convenient for assembly and maintenance, and the water purification module 200 and the heating module 300 do not interfere with each other.

[0068] Alternatively, the pump 330 may be installed on the side of the water purification base 210 facing away from the water purification system, that is, the pump 330 and the water purification system are located on different sides of the water purification base 210, for example, the pump 330 is located on the outer bottom wall of the water purification base 210, so that the waterproof effect is better. According to some embodiments of the present invention, such as Figure 6 As shown, the top of the clean water tank 500 is provided with a first exhaust port 501, and the housing 100 is provided with a second exhaust port 102. The first exhaust port 501 is connected with the second exhaust port 102, so that it can simultaneously exhaust air and remind the user that water has overflowed, wherein the first exhaust port 501 can be connected by a pipeline. For example, the second exhaust port 102 is located on the front surface of the housing 100, and the clean water tank 500 stops taking in water when pure water enters and is stored to a certain water level, and exhaust is required in this process; and if the machine is out of control and cannot stop taking in water, the excess water will flow out through the second exhaust port 102. Since this position is on the front of the machine, the user can intuitively see that there is water, and can immediately cut off the power for maintenance to prevent safety problems such as electric shock.

[0069] According to some embodiments of the present invention, Figure 3-Figure 5 As shown, the water purification base 210 includes: a base 211 and a barrel 212. The barrel 212 is mounted on the base 211, the filter element assembly 220 is mounted in the barrel 212, and the booster pump and the flushing valve 230 are respectively mounted on the outer peripheral wall of the barrel 212. In this way, the filter element assembly 220 can be easily replaced, and the assembly and maintenance of the booster pump and the flushing valve 230 are also convenient.

[0070] According to some embodiments of the present invention, Figure 3-Figure 5 As shown, the heating base 310 includes: a base plate 311 and a partition plate 312. The heating element 320, the water pump 330 and the electric control board 340 are installed on the right surface of the base plate 311. The partition plate 312 is connected to the side edge of the base plate 311, and the partition plate 312 exceeds the right surface of the base plate 311 in the horizontal direction. In this way, the partition plate 312 can further separate the water purification module 200 and the heating module 300, and the safety and convenience are better.

[0071] Furthermore, if Figure 3-Figure 5 As shown, there are multiple partition plates 312, and the multiple partition plates 312 are respectively connected to the front edge, rear edge and lower edge of the substrate 311, so that the heating element 320, the water pump 330 and the electric control board 340 are installed in the space surrounded by the substrate 311 and the multiple partition plates 312, which is safer and more convenient.

[0072] In some embodiments of the present invention, Figure 3 and Figure 4As shown, the electric control board 340 is adjacent to the rear edge of the base plate 311, the water pump 330 and the heating element 320 are adjacent to the front edge of the base plate 311, and the booster pump and the flushing valve 230 are adjacent to the rear edge of the base plate 311 (for example, the flushing valve 230 is located above the booster pump). In this way, the structure is relatively compact, which greatly improves the space utilization and is convenient for assembly and maintenance operations.

[0073] The heating element 320 can be located above the water pump 330, so that the water pump 330 can pump water from the clean water tank 500 below, and hot water can flow from the heating element 320 to the water outlet 11. Optionally, a water receiving box 103 can be set below the water outlet 11 to prevent water leakage.
