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

[0042] A hot pot assembly 10 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0043] like Figure 3 and Figure 4 As shown, the hot tank assembly 10 according to the embodiment of the utility model is used for a water purification device 100 and includes a heating tank 1 and a water level detection component 2. For example, the water purification device 100 can be a water purifier, a water purifier, or a water-using device with a heating function or a cooling function, and can perform deep filtration and purification on the water quality according to the user's requirements for water use.

[0044] Specifically, refer to the attached Figure 5 and attached Figure 6 As shown, the heating tank 1 has a heating chamber 13, and the heating tank 1 is also provided with a water inlet and a water outlet, both of which are connected to the heating chamber 13, and cold water can enter the heating chamber 13 from the water inlet, and be heated to a suitable temperature in the heating chamber 13, and then flow out from the water outlet, which can meet the user's demand for hot water and facilitate direct drinking or use by the user. It should be noted that due to the existence of the heating chamber 13, a portion of water can be pre-stored and heated in the hot tank assembly 10, and water can be quickly discharged when the user needs to use hot water or warm water, without waiting for the cold water to be heated, ensuring that the user can obtain hot water of suitable temperature at any time, shortening the user's waiting time, and greatly improving the user's experience.

[0045] Further, see Attachment Figure 5 and attached Figure 6As shown, the water level detection component 2 is arranged on the heating tank 1 and is used to detect the lowest water level and the highest water level in the heating chamber 13. The lowest water level is lower than the highest water level. The water level detection component 2 includes a common probe 21, a low water level probe 22 and a high water level probe 23. The common probe 21, the low water level probe 22 and the high water level probe 23 are arranged at intervals. The common probe 21, the low water level probe 22 and the high water level probe 23 are at least partially located in the heating chamber 13. The water level in the heating chamber 13 can be detected by directly contacting the common probe 21, the low water level probe 22 and the high water level probe 23 with water, so that the water level detection component 2 can detect the water level height in the heating chamber 13 in real time, thereby improving the accuracy of the water level detection component 2 for detecting the water level in the heating chamber 13 and ensuring that the heating chamber 13 operates within a suitable water level range.

[0046] Further, see Appendix Figure 5 and attached Figure 6 As shown, the lower end of the common probe 21 is lower than the lower end of the low water level probe 22 or is flush with the lower end of the low water level probe 22, and the lower end of the high water level probe 23 is higher than the lower ends of the low water level probe 22 and the common probe 21. The low water level probe 22 is used to cooperate with the common probe 21 to detect whether the water in the heating chamber 13 is lower than the lowest water level; the high water level probe 23 is used to cooperate with the common probe 21 to detect whether the water in the heating chamber 13 exceeds the highest water level.

[0047] When the water level detection component 2 detects that the low water level probe 22 is disconnected from the common probe 21, it is judged that the water level in the heating chamber 13 is lower than the lowest water level, and the hot water in the heating chamber 13 is stopped from flowing out of the water outlet, and the cold water is controlled to enter the heating chamber 13 from the water inlet, so as to avoid dry boiling due to the low water level in the heating tank 1 and damage to the hot tank assembly 10; when the water level detection component 2 detects that the high water level probe 23 is connected to the common probe 21, it is judged that the water level in the heating chamber 13 is at the highest water level, and further adding water to the heating chamber 13 is stopped to ensure that the water level in the heating chamber 13 is separated from the inner top wall of the heating chamber 13, so as to prevent the heating chamber 13 from overflowing due to the high water level, avoid wasting water resources and polluting the environment, and prevent water from spraying out and causing injuries to users.

[0048] Alternatively, if Figure 6 As shown, the lower end of the common probe 21 may be flush with the lower end of the low water level probe 22, as shown in FIG. Figure 5 As shown, the lower end of the common probe 21 may be lower than the lower end of the low water level probe 22, and the lower end of the common probe 21 may be lower than the lower end of the low water level probe 22. Figure 6), the distance between the lower end of the low water level probe 22 and the lower end of the common probe 21 is 0mm-15mm, which can ensure that when the water level in the heating chamber 13 is lower than the lowest water level, the low water level probe 22 and the common probe 21 are disconnected, and ensure that when the water level in the heating chamber 13 is at the lowest water level or higher than the lowest water level, the low water level probe 22 and the common probe 21 are connected. For example, in the up and down direction, the distance between the lower end of the low water level probe 22 and the lower end of the common probe 21 can be 0mm, 2mm, 4mm, 5mm, 7mm, 8mm or 10mm.

[0049] According to the hot pot assembly 10 of the embodiment of the utility model, the water level detection component 2 includes a common probe 21, a low water level probe 22 and a high water level probe 23. The common probe 21, the low water level probe 22 and the high water level probe 23 are at least partially located in the heating chamber 13. The lower end of the common probe 21 is lower than the lower end of the low water level probe 22 or is flush with the lower end of the low water level probe 22. The lower end of the high water level probe 23 is higher than the lower ends of the low water level probe 22 and the common probe 21. 22 and the high water level probe 23 are in direct contact with water to detect the water level in the heating chamber 13, so that the water level detection component 2 can detect the water level height in the heating chamber 13 in real time, improve the accuracy of the water level detection component 2 for water level detection in the heating chamber 13, ensure that the heating chamber 13 operates within a suitable water level range, avoid dry burning due to low water level in the heating tank 1, prevent overflow of the heating chamber 13 due to high water level, avoid damage to the hot tank assembly 10, extend the service life of the hot tank assembly 10, and improve the user experience.

[0050] In some embodiments of the present invention, refer to the attached Figure 6 As shown, the distance between the lower end surface of the common probe 21 and the inner bottom wall of the heating chamber 13 is a, and satisfies: 5mm≤a≤20mm, which can avoid the distance between the lower end surface of the common probe 21 and the inner bottom wall of the heating chamber 13 being too close, avoid the setting of the lowest water level too low, and avoid the water level detection component 2 judging that the water level in the heating chamber 13 is at the lowest water level, which causes dry burning and affects the service life of the hot pot assembly 10. For example, the distance a between the lower end surface of the common probe 21 and the inner bottom wall of the heating chamber 13 can be 5mm, 8mm, 10mm, 12mm, 15mm, 17mm or 20mm.

[0051] Further, see Attachment Figure 6As shown, the distance between the lower end surface of the low water level probe 22 and the inner bottom wall of the heating chamber 13 is b, and satisfies: 5mm≤b≤20mm, which can avoid the distance between the lower end surface of the low water level probe 22 and the inner bottom wall of the heating chamber 13 being too close, avoid the setting of the lowest water level too low, and avoid the water level detection component 2 judging that the water level in the heating chamber 13 is at the lowest water level, which causes dry burning and affects the service life of the hot pot assembly 10. For example, the distance b between the lower end surface of the low water level probe 22 and the inner bottom wall of the heating chamber 13 can be 5mm, 8mm, 10mm, 12mm, 15mm, 17mm or 20mm.

[0052] In some embodiments of the present invention, refer to the attached Figure 6 As shown, the distance between the lower end face of the high water level probe 23 and the inner top wall of the heating chamber 13 is c, and satisfies: 10mm≤c≤40mm, which can avoid the distance between the lower end face of the high water level probe 23 and the inner top wall of the heating chamber 13 being too close, avoid the setting of the highest water level too high, and avoid the water level in the heating chamber 13 overflowing when the water level detection component 2 determines that the water level in the heating chamber 13 is at the highest water level, resulting in a waste of water resources and affecting the safety of users. For example, the distance c between the lower end face of the high water level probe 23 and the inner top wall of the heating chamber 13 can be 10mm, 15mm, 20mm, 25mm, 30mm, 35mm or 40mm.

[0053] In some embodiments of the present invention, refer to the attached Figure 6 and attached Figure 7 As shown, the high water level probe 23 includes a first probe 231 and a second probe 232, and the first probe 231 and the second probe 232 are arranged at intervals. The distance between the lower end surface of the first probe 231 and the inner top wall of the heating chamber 13 is equal to the distance between the lower end surface of the second probe 232 and the inner top wall of the heating chamber 13. The arrangement of the first probe 231 and the second probe 232 can play a double insurance role. When one of the first probe 231 and the second probe 232 is misjudged or the signal fails, the other of the first probe 231 and the second probe 232 can work normally, thereby ensuring the normal operation of the high water level probe 23, ensuring the accuracy and timeliness of the high water level probe 23 for detecting the highest water level, and stopping the addition of water to the heating chamber 13 when the water level in the heating chamber 13 reaches the highest water level, preventing the water level in the heating chamber 13 from being too high, avoiding excessive pressure in the heating chamber 13 due to boiling hot water, and avoiding the danger of rupture of the heating tank 1, thereby improving the reliability of the hot tank assembly 10.

[0054] In some embodiments of the utility model, the water level in the heating chamber 13 also has an intermediate water level. In the up and down directions, the intermediate water level is located between the lowest water level and the highest water level. The water level detection component 2 is also used to detect the intermediate water level in the heating chamber 13. The intermediate water level can be calculated by an algorithm. Specifically, the intermediate water level is half of the time difference for the water level to rise from the lower end surface of the low water level probe 22 to the lower end surface of the high water level probe 23 when water is added to the heating chamber 13. It can be selected according to user needs whether to replenish water when the water level drops to the lowest water level or to replenish water when the water level drops to the intermediate water level to meet different usage requirements. It can be understood that the detection of low water level, high water level and middle water level can be achieved only by the common probe 21, the low water level probe 22 and the high water level probe 23. The cost of the hot tank assembly 10 can be saved by a simple algorithm, so that the water adding and water taking modes of the heating tank 1 are rich and optional.

[0055] In a further embodiment of the present invention, the hot tank assembly 10 also includes a middle water level probe, at least part of which is located in the heating chamber 13, and the lower end of the middle water level probe is higher than the lower ends of the low water level probe 22 and the common probe 21 and lower than the lower end of the high water level probe 23. The middle water level probe is used to cooperate with the common probe 21 to detect whether the water level in the heating chamber 13 is lower than the middle water level. When the water level detection component 2 detects that the middle water level probe is disconnected from the common probe 21, it is judged that the water level in the heating chamber 13 is lower than the middle water level. When the hot tank assembly 10 is set to replenish water when the water level in the heating chamber 13 is lower than the middle water level, the hot water in the heating chamber 13 is stopped from flowing out of the water outlet, and the cold water is controlled to enter the heating chamber 13 from the water inlet to avoid dry burning due to too low water level in the heating tank 1, thereby avoiding damage to the hot tank assembly 10. It should be noted that, through the dual protection of algorithm and structure, the water level detection component 2 can ensure accurate detection of low water level, middle water level and high water level, and ensure the water addition and water extraction of the hot tank assembly 10.

[0056] In some embodiments of the present invention, refer to the attached Figure 5 As shown, the heating tank 1 includes a tank body 11 and a cover plate 12. The upper end of the tank body 11 has an open mouth, and the cover plate 12 is covered at the open mouth. The tank body 11 and the cover plate 12 jointly define a heating chamber 13. The water level detection component 2 is detachably arranged on the cover plate 12, which can make the disassembly and replacement of the water level detection component 2 more convenient, reduce the difficulty of disassembly and maintenance of the water level detection component 2, shorten the maintenance time of the hot tank assembly 10, and reduce the maintenance cost of the hot tank assembly 10.

[0057] In a further embodiment of the present invention, refer to the attached Figure 7 and attached Figure 8As shown, a mounting hole 121 is provided on the cover plate 12, and the water level detection component 2 also includes a mounting seat 24, which is arranged at the mounting hole 121 and is detachably connected to the cover plate 12, and the common probe 21, the low water level probe 22 and the high water level probe 23 are all arranged on the mounting seat 24, so that the water level detection component 2 can be limited in the horizontal direction relative to the cover plate 12 to prevent the water level detection component 2 from moving or rotating and causing the water level detection component 2 to interfere with other components, thereby causing damage to the water level detection component 2, and the service life of the water level detection component 2 can be extended.

[0058] Further, see Attachment Figure 7 and attached Figure 8 As shown, the water level detecting component 2 is suitable for being installed on the cover plate 12 from top to bottom, and is suitable for being removed from the cover plate 12 from bottom to top, so that the cover plate 12 can limit the water level detecting component 2 upward to prevent the water level detecting component 2 from falling into the heating chamber 13 and losing the function of detecting the water level. In addition, the water level detecting component 2 and the cover plate 12 can be detachable, making the disassembly and replacement of the water level detecting component 2 more convenient and reducing the difficulty of repairing the water level detecting component 2.

[0059] For details, please refer to the attached Figure 8 As shown, after the mounting seat 24 is placed at the mounting hole 121, it is connected to the cover plate 12 through a fastener, which can ensure the detachable connection between the water level detection component 2 and the cover plate 12. For example, the fastener can be a screw.

[0060] The utility model also provides a water purification device 100 having the hot tank assembly 10 of the above embodiment.

[0061] like Figure 1 and Figure 2 As shown, the water purification device 100 according to the embodiment of the present utility model includes the above-mentioned hot tank assembly 10 and a water inlet valve.

[0062] Specifically, refer to the attached Figure 1 and attached Figure 2 As shown, the water inlet valve is arranged on the pipeline supplying water to the heating tank 1 or at the water inlet of the heating tank 1. When the water level in the heating chamber 13 is higher than the maximum water level, the water inlet valve is closed, and when the water level in the heating chamber 13 is lower than the minimum water level, the water inlet valve is opened.

[0063] It is understandable that when the water level in the heating chamber 13 is lower than the minimum water level, the water inlet valve is opened to allow cold water to enter the heating chamber 13 from the water inlet, so that the heating chamber 13 can have sufficient water to meet the user's water demand, and can prevent the water level in the heating chamber 13 from being too low and causing dry burning, causing the heating tank 1 to continue to heat up and cause danger; if the heating chamber 13 is continuously full of water, when the user takes water, cold water continuously enters the heating chamber 13 from the water inlet, then the user may get a mixture of normal temperature water and hot water, which cannot meet the user's demand for high temperature water, and the setting of the water inlet valve can control whether cold water enters the heating chamber 13 from the water inlet, and then control the amount of water stored in the heating chamber 13 to prevent water from boiling and overflowing. In addition, the setting of the water inlet valve can also control the time of water replenishment in the heating chamber 13, for example, when the user takes water, the water inlet valve is closed so that the water obtained by the user can meet the temperature requirements.

[0064] For example, the water purification device 100 may be a water purifier, a water purifier, or a water-using device with a heating function or a cooling function, and may perform deep filtration and purification on the water according to the user's water usage requirements.

[0065] Further, see Attachment Figure 1 and attached Figure 2 As shown, the water purification device 100 also includes a housing 30, a first filter element 40 and a second filter element 50. The hot tank assembly 10, the water inlet valve, the first filter element 40 and the second filter element 50 are all arranged in the housing 30. The housing 30 can protect the internal structure of the water purification device 100 to prevent the internal structure of the water purification device 100 from being exposed and damaged, which is beneficial to extending the service life of the water purification device 100 and has a good appearance effect. Furthermore, the first filter element 40 is a PCB filter element (pre-carbon block filter element), which uses activated carbon as the core filter medium, and effectively removes residual chlorine, odor, color and organic pollutants in the water through physical adsorption and chemical reaction, thereby improving water quality. However, it should be noted that the filtering effect of the PCB filter element in water treatment is relatively limited, and it is unable to remove soluble ions and heavy metals in water. The second filter element 50 is a RO filter element (reverse osmosis filter element), which adopts reverse osmosis technology and removes impurities such as dissolved salts, colloids, microorganisms, organic matter, etc. in water by physical methods to achieve the purpose of purifying water quality. Its pore size is extremely small, usually about 0.1 nanometers, and can effectively prevent bacteria, viruses, heavy metals and other harmful substances from passing through. The second filter element 50 can make up for the defects of the first filter element 40 and can further purify the water. Therefore, through the combined use of the first filter element 40 and the second filter element 50, the filtering accuracy of the water purification equipment 100 can be improved, the safety of users' water use can be guaranteed, and the user experience can be improved.
