For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] The hot pot assembly 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0040] like Figure 1 and Figure 4 As shown, the hot tank assembly 100 according to the embodiment of the present utility model includes a hot tank body 1, a first temperature sensor 2 and a second temperature sensor 3.

[0041] Specifically, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the hot tank assembly 100 is used for a water purification device, which may be a water purifier, a beverage purifier, or a water-using device with a heating function or a cooling function. A first temperature sensor 2 is provided on the hot tank body 1 to detect the water temperature in the hot tank body 1, and a second temperature sensor 3 is provided on the hot tank body 1 to detect the steam temperature in the hot tank body 1.

[0042] It can be understood that the hot tank assembly 100 plays the role of water storage and heating. The hot tank body 1 can store drinking water to be heated and after heating. The hot tank assembly 100 can be provided with a heating assembly 7 for heating the drinking water in the hot tank body 1. The hot tank assembly 100 is provided with a first temperature sensor 2 and a second temperature sensor 3 that can detect the temperature in real time and accurately. The first temperature sensor 2 can be arranged at the bottom of the hot tank body 1 to facilitate the detection of the water temperature in the hot tank body 1. The second temperature sensor 3 is arranged at the top of the hot tank body 1 to facilitate the detection of the steam temperature in the hot tank body 1. A control board can also be provided in the hot tank assembly 100. The first temperature sensor 2 and the second temperature sensor 3 are both connected to the control board in communication. The first temperature sensor 2 and the second temperature sensor 3 can convert the detected temperature information into electrical signals and transmit the electrical signals to the control board for processing.

[0043] Among them, the first temperature sensor 2 arranged on the hot tank body 1 can detect the water temperature in the hot tank body 1. According to the monitored water temperature, the first temperature sensor 2 will send a signal to the control board, and the control board will control the start or stop of the heating of the drinking water in the hot tank body 1 according to the received signal, so that the water temperature is kept within the set range.

[0044] Furthermore, the second temperature sensor 3 provided on the hot tank body 1 can detect the steam temperature in the hot tank body 1. When the heating of the drinking water in the hot tank body 1 is turned on, the water temperature of the drinking water in the hot tank body 1 slowly rises to boiling and gradually generates steam. At this time, the second temperature sensor 3 detects the temperature of the steam. When the drinking water in the hot tank body 1 continues to boil, the temperature of the generated steam no longer rises. At this time, the steam temperature detected by the second sensor can be determined as the boiling point temperature of the place.

[0045] In the related art, since the use location of the hot tank assembly is unclear, the highest temperature of the water in the hot tank body is generally set manually as the boiling point temperature. For example, the above highest temperature is generally set at around 90℃-94℃ to adapt to most application scenarios. However, for areas with lower altitudes, the water at the above highest temperature has not really boiled, and boiled water cannot be obtained, which poses a risk of incomplete disinfection. For high-altitude areas with lower boiling points, the drinking water in the hot tank body boils before reaching the above highest temperature, but the boiled water will continue to be heated, and there is a risk of the water being heated continuously until it is dried up, which can easily cause damage to the hot tank assembly.

[0046] In the present application, the second temperature sensor 3 can determine the boiling point temperature of the water at the location of the hot tank assembly 100 by detecting the steam temperature in the hot tank body 1. The second temperature sensor 3 transmits the detected steam temperature signal to the control board. The control board can determine the boiling point temperature based on the received steam temperature signal. At the same time, when the first temperature sensor 2 detects that the water temperature in the hot tank body 1 reaches the boiling point, the control stops heating the drinking water in the hot tank body 1, so that the hot tank assembly 100 can adapt to various locations with different altitudes, which can ensure that the drinking water is boiled and thoroughly disinfected to provide safe hot water, improve the user's experience, and avoid the water in the hot tank body 1 from being repeatedly heated and continuously boiled after boiling, thereby reducing the risk of damage to the hot tank assembly 100 and the drinking water equipment.

[0047] It should be noted that the first temperature sensor 2 and the second temperature sensor 3 may be temperature sensing elements such as thermistors, and the resistance values ​​of the first temperature sensor 2 and the second temperature sensor 3 change with the temperature. When the water temperature in the hot tank body 1 changes, the resistance value of the first temperature sensor 2 changes accordingly, is converted into a voltage or current signal through the circuit, and is transmitted to the control board for processing. When the steam temperature in the hot tank body 1 changes, the resistance value of the second temperature sensor 3 changes accordingly, is converted into a voltage or current signal through the circuit, and is transmitted to the control board for processing.

[0048] According to the hot tank assembly 100 of the embodiment of the utility model, by arranging a first temperature sensor 2 for detecting the water temperature in the hot tank body 1 on the hot tank body 1, and arranging a second temperature sensor 3 for detecting the steam temperature in the hot tank body 1 on the hot tank body 1, the boiling point temperature of the water at the location of the hot tank assembly 100 can be determined by detecting the steam temperature in the hot tank body 1 by the second temperature sensor 3, and the water temperature in the hot tank body 1 can be detected in real time by the first temperature sensor 2 to control the start or stop of heating the water in the hot tank body 1. When the water temperature in the hot tank body 1 reaches the local boiling point temperature, the heating can be stopped, which can ensure that the drinking water is boiled and thoroughly disinfected to provide safe hot water, improve the user's sense of use, and avoid the water in the hot tank body 1 from being repeatedly heated and continuously boiled after boiling, thereby reducing the risk of damage to the hot tank assembly 100 and the drinking water equipment.

[0049] In some embodiments of the present invention, Figure 4 , Figure 5 and Figure 6 As shown, the bottom of the hot pot body 1 is provided with a heating plate 4, and the hot pot assembly 100 further includes a heating assembly 7, which is arranged below the heating plate 4 and used to heat the heating plate 4. The first temperature sensor 2 is used to detect the temperature of the heating plate 4 and indirectly detect the water temperature in the hot pot body 1. The heating plate 4 heated by the heating assembly 7 can evenly heat the drinking water in the hot pot body 1, and the heating plate 4 can be made of metal materials such as stainless steel, which has good thermal conductivity. Since the drinking water is stored in the hot pot body 1, and the first temperature sensor 2 is inconvenient to be arranged in the hot pot body 1, by arranging the heating plate 4 and making the first temperature sensor 2 detect the temperature of the heating plate 4, such as arranging the first temperature sensor 2 below the heating plate 4, the drinking water in the hot pot body 1 fits with the heating plate 4, and the temperature of the drinking water will be transmitted to the heating plate 4, and the heating plate 4 will then transmit the temperature to the first temperature sensor 2, so that the first temperature sensor 2 can detect the temperature of the heating plate 4 to obtain the temperature of the hot water in the hot pot body 1, which is convenient and can avoid direct contact between the first temperature sensor 2 and water, thereby ensuring the safety of the first temperature sensor 2.

[0050] In some embodiments of the present invention, Figure 4 , Figure 5 and Figure 6 As shown, the first temperature sensor 2 is located below the heating plate 4 and fits the heating plate 4. The first temperature sensor 2 is convenient for detecting the temperature of the heating plate 4 and ensuring the accuracy of the detected temperature, thereby detecting the temperature of the water in the hot pot body 1.

[0051] In some embodiments of the present invention, Figure 4 , Figure 5 and Figure 7As shown, the hot pot assembly 100 also includes a mounting bracket 5, which is connected to the heating plate 4 and is used to fix the first temperature sensor 2 on the heating plate 4. It is convenient to install and fix the first temperature sensor 2, which can enhance the connection stability between the first temperature sensor 2 and the heating plate 4, and ensure that the first temperature sensor 2 can fit the heating plate 4, thereby ensuring the accuracy of the first temperature sensor 2 detecting the temperature of the heating plate 4.

[0052] Furthermore, if Figure 4 , Figure 5 and Figure 7 As shown, the mounting bracket 5 and the heating plate 4 can be connected by fasteners, and a plurality of mounting columns 42 can be provided on the heating plate 4. The mounting bracket 5 is provided with a plurality of first fixing holes 51 corresponding to the plurality of mounting columns 42 one by one. The operator can pass the first fixing holes 51 of the mounting bracket 5 through the mounting columns 42 on the heating plate 4, and then fix fasteners such as nuts on the mounting columns 42, thereby completing the fixed connection between the mounting bracket 5 and the heating plate 4.

[0053] Among them, the mounting bracket 5 is also provided with a second fixing hole 52, and the first temperature sensor 2 is passed through the second fixing hole 52, so that it can be fixed on the heating plate 4 through the mounting bracket 5, so that at least part of the first temperature sensor 2 is clamped between the mounting bracket 5 and the heating plate 4, which can ensure that the end of the first temperature sensor 2 close to the heating plate 4 is in contact with the heating plate 4, so as to ensure that the first temperature sensor 2 detects the temperature of the heating plate 4 and indirectly detects the water temperature in the hot tank body 1.

[0054] In some embodiments of the present invention, Figure 4 , Figure 5 and Figure 6 As shown, the lower surface of the heating plate 4 has an upwardly concave groove 41, and the first temperature sensor 2 is arranged in the groove 41 and fits with the bottom wall and / or side wall of the groove 41, so that the first temperature sensor 2 can detect the temperature of the heating plate 4. The groove 41 can form a accommodating space, which is convenient for the placement of the first temperature sensor 2, and ensures that the end of the first temperature sensor 2 close to the heating plate 4 is in contact with the heating plate 4, while the first temperature sensor 2 can be placed in a space surrounded by the heating plate 4, reducing the interference of other components to the first temperature sensor 2, thereby ensuring that the temperature of the heating plate 4 detected by the first temperature sensor 2 is more accurate, thereby improving the accuracy of the water temperature detected in the hot pot body 1. In addition, the space outside the hot pot body 1 occupied by the first temperature sensor 2 can be saved, and the first temperature sensor 2 can be prevented from being protruding from the bottom of the heating plate 4, thereby causing interference with other components.

[0055] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 3 As shown, the top wall of the hot pot body 1 has a mounting hole 121, and the second temperature sensor 3 is arranged in the mounting hole 121 and at least partially exposed inside the hot pot body 1. Thus, the second temperature sensor 3 can extend into the interior of the hot pot body 1 through the mounting hole 121, and at least part of the second temperature sensor 3 is exposed inside the hot pot body 1, so that it can contact the steam in the hot pot body 1 to detect the steam temperature, and then determine the boiling point temperature at the location.

The first annular boss 141 can support the second temperature sensor 3, and the structural design is reasonable. At the same time, the first annular boss 141 is provided with a through hole connected to the mounting hole 121. The second temperature sensor 3 can pass through the through hole of the first annular boss 141 and be inserted into the mounting hole 121, thereby extending into the interior of the hot tank body 1, so as to contact the steam in the hot tank body 1 and detect the steam temperature, and then the boiling point temperature at the location can be determined.

[0058] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the second temperature sensor 3 is provided with a connecting plate 31, the connecting plate 31 is located outside the hot tank body 1, and a connecting boss 142 is also provided on the outer top wall of the mounting plate 14, and the connecting plate 31 is connected to the connecting boss 142 by a fastener.

[0071] According to the water purification device of the embodiment of the utility model, by arranging a first temperature sensor 2 for detecting the water temperature in the hot tank body 1 on the hot tank body 1 in the hot tank assembly 100, and arranging a second temperature sensor 3 for detecting the steam temperature in the hot tank body 1 on the hot tank body 1, the boiling point temperature of the water at the location of the hot tank assembly 100 can be determined by detecting the steam temperature in the hot tank body 1 by the second temperature sensor 3, and the water temperature in the hot tank body 1 can be detected in real time by the first temperature sensor 2 to control the start or stop of heating the water in the hot tank body 1. When the water temperature in the hot tank body 1 reaches the local boiling point temperature, the heating can be stopped, which can ensure that the drinking water is boiled and thoroughly disinfected to provide safe hot water, improve the user's sense of use, and avoid the water in the hot tank body 1 from being repeatedly heated and continuously boiled after boiling, reduce the risk of damage to the hot tank assembly 100 and the water purification device, and thus expand the application scenarios of the water purification device and improve the stability and reliability of the water purification device.

[0072] In some embodiments, the second temperature sensor 3 can detect the steam temperature in the hot tank body 1. When the heating of the drinking water in the hot tank body 1 is turned on, the water temperature of the drinking water in the hot tank body 1 slowly rises to boiling and gradually generates steam. At this time, the second temperature sensor 3 detects the temperature of the steam. When the drinking water in the hot tank body 1 continues to boil, the temperature of the generated steam no longer rises. At this time, the second sensor transmits the signal of the detected steam temperature to the control board, and the control board can determine the boiling point temperature of the place, thereby obtaining the boiling point T1 of the water in the hot tank body 1.

[0073] At the same time, the first temperature sensor 2 can detect the water temperature in the hot tank body 1 and transmit the signal to the control board, and the control board can make a judgment and control the heating according to the received water temperature signal.

[0074] When the control panel determines that the temperature of the water in the hot tank body 1 is less than T1-T2, the control panel controls the heating component 7 of the hot tank body 1 to heat at the first power until the temperature of the water in the hot tank body 1 reaches T1-T3. When the control panel determines that the temperature of the water in the hot tank body 1 is greater than T1-T3, the control panel controls the heating component 7 of the hot tank body 1 to heat at the second power until the water in the hot tank body 1 reaches the boiling point T1 and stops heating, wherein the first power is greater than the second power. In this way, the energy consumption of heating the water purifier can be reduced while ensuring that the drinking water is boiled. When the temperature of the water in the hot tank body 1 is greater than T1-T3 and lower than the boiling point T1, the second power, i.e., low power, is used for heat preservation, thereby ensuring that the user can obtain hot water at any time, and improving the user's sense of use and experience.

[0075] At the same time, by heating the water in the hot tank body 1 through the above-mentioned control method, it can ensure that the drinking water is boiled and thoroughly disinfected to provide safe hot water, thereby improving the user's experience, and it can also avoid the water in the hot tank body 1 from being repeatedly heated and continuously boiled after boiling, thereby reducing the risk of damage to the hot tank assembly 100 and the water purification equipment.

[0076] In a specific implementation process, the first power may be 1500W, and the second power may be 150W. The values ​​of the first power and the second power may be adjusted according to actual conditions, and the present invention does not make any specific limitation on this.

[0077] Among them, T2 satisfies: 8℃≤T2≤12℃. If T2 is less than 8℃, the range in which the heating component 7 of the hot tank body 1 needs to heat at the first power is too large, and the heating component 7 of the hot tank body 1 frequently turns on the first power for heating, resulting in increased energy consumption. If T2 is greater than 12℃, after the water temperature in the hot tank body 1 drops, the heating component 7 will still not be controlled to heat at the first power, which may cause the temperature of the hot water received by the user to be too low, affecting the user's experience. Making 8℃≤T2≤12℃ can not only ensure that the energy consumption is not too large, but also can heat in time to ensure that the user can get hot water at any time, thereby improving the user's sense of use and experience.

[0078] Furthermore, T3 satisfies: 3℃≤T3≤6℃. If T3 is less than 3℃, the range of heating by the heating component 7 of the hot tank body 1 at the first power is too large, and the heating component 7 of the hot tank body 1 frequently turns on the first power for heating, resulting in increased energy consumption. If T3 is greater than 6℃, the range of heating by the heating component 7 of the hot tank body 1 at the second power is too large, and the speed of heating at the second power is slow after the water temperature in the hot tank body 1 is lowered, which may cause the temperature of the hot water received by the user to be too low, affecting the user's experience. Making 3℃≤T3≤6℃ can not only ensure that the energy consumption is not too large, but also can heat in time to ensure that the user can get hot water at any time, thereby improving the user's sense of use and experience.

[0079] In some embodiments, the second temperature sensor 3 disposed on the top of the hot tank body 1 can detect the steam temperature in the hot tank body 1. When the heating of the drinking water in the hot tank body 1 is turned on, the water temperature of the drinking water in the hot tank body 1 slowly rises to boiling and gradually generates steam. When the drinking water in the hot tank body 1 continues to boil, the temperature of the generated steam no longer rises. At this time, the second sensor transmits the signal of the detected steam temperature to the control board in real time. If the steam temperature in the hot tank body 1 detected by the second temperature sensor 3 does not rise within the preset time, the control board uses the current steam temperature in the hot tank body 1 as the boiling point temperature of the place, that is, the boiling point T1 of the water. The above method can ensure the accuracy of the obtained boiling point T1 of the water.

[0080] Among them, the preset time is 30-90s. If the preset time is less than 30s, the time for the steam temperature in the hot tank body 1 to remain stable is still short, and the drinking water in the hot tank body 1 is very likely not to boil. Therefore, it is biased to judge that the drinking water in the hot tank body 1 has boiled at this time, which may lead to inaccurate boiling point T1. If the preset time is greater than 90s, it is judged that the water in the hot tank body 1 has been boiling for too long, and the water in the hot tank body 1 may have been boiling for a long time and is continuously heated, which may increase energy consumption. The preset time is 30-90s, which can not only ensure the accuracy of the boiling point T1 obtained, but also avoid the continuous heating of the water in the hot tank body 1 when boiling, thereby controlling energy consumption.
