Description

Technical Field

[0002] With the gradual improvement of people's living standards and the increasing awareness of health, the quality requirements for drinking water have become more and more stringent. In such a trend, water purification devices with the functions of effectively filtering impurities and significantly improving water quality have gradually become popular and become a common choice for many families, providing an important guarantee for people's daily drinking water safety and health.

[0003] In the current related technology field of water purification devices, in order to further meet the diverse needs of users, some representative water purification devices such as integrated water purification and heating devices are specially equipped with an additional heating function. During normal operation, a large amount of heat will be generated inside. Since the overall design framework inside the device was not fully and comprehensively considered in terms of heat dissipation and subsequent impacts during the preliminary planning, and limited by the established spatial distribution pattern, these heats are difficult to be effectively channeled and controlled. As a result, the dissipated heat will spread wantonly to the surrounding area, and then cause varying degrees of negative impacts on other key components inside the device. Summary of the Invention

[0061] To make the purpose, technical solutions and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

[0062] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods that are consistent with some aspects of the present application as detailed in the appended claims.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0064] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the description of this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0065] Please refer to Figures 1 to 4 , the present application provides a combined water purification and heating machine 1. In the embodiment of the present application, the combined water purification and heating machine 1 includes a housing assembly 10, a filtration system 50, and a hot water tank assembly 20.

[0066] Among them, the housing assembly 10 serves as the external framework of the entire combined water purification and heating machine 1, and its overall outer contour is set in a rectangular shape. It is particularly suitable for installation and placement in the kitchen area. The kitchen usually has regular cabinet space, and the rectangular combined water purification and heating machine 1 can be easily embedded under the cabinet or placed in the corner of the kitchen countertop, integrating with the overall kitchen environment.

[0067] The filtration system 50 is a key part of the integrated water purifier and heater 1. By being installed inside the housing assembly 10, it makes full use of the protective performance of the housing, avoiding the interference of dust, water vapor, and other possible pollutants to the filtration process, thus ensuring the reliability and stability of the filtration effect. The filtration system 50 and the hot water tank assembly 20 are connected through the water circuit board 60 or water pipes. The filtration system 50 includes a primary filter element 51, a secondary filter element 52, and a booster pump 53. The primary filter element 51 and the secondary filter element 52 are connected and communicated through the water circuit board 60. The booster pump 53 is used to transport the liquid filtered by the primary filter element 51 to the secondary filter element 52 through the water circuit board 60. The primary filter element 51 can be PAC (Polyaluminium Chloride). As the primary filtration unit, it mainly intercepts and removes larger particulate impurities, suspended solids, some colloids, and some microorganisms in the water. The filtration material it uses has a larger pore size and surface area, which can efficiently capture these larger pollutants and prevent them from entering the subsequent filtration links, thus protecting the secondary filter element 52 from excessive clogging and pollution and extending the service life of the entire filtration system 50. The booster pump 53 plays an important role as the power in the filtration system 50. Its main function is to provide sufficient pressure for the water filtration process to ensure that the water preliminarily filtered by the primary filter element 51 can enter the secondary filter element 52 for deep purification through the water circuit board 60 or water pipes at a stable and appropriate flow rate. The water preliminarily filtered by the primary filter element, under the action of the booster pump 53, is transported to the secondary filter element through the water circuit board 60 or water pipes. The secondary filter element can be RO (Reverse Osmosis), which is the key link for achieving deep purification. It uses a more refined filtration material and can effectively remove harmful substances such as residual fine particles, dissolved organic matter, heavy metal ions, bacteria, and viruses in the water. These tiny pollutants often pose a potential threat to human health. Through the fine filtration of the secondary filter element, it can ensure the provision of safe, pure, and healthy drinking water for users.

[0068] The hot water tank assembly 20 is used to store and heat the filtered pure water, so as to meet the user's demand for hot water at any time, enhancing the functionality and practicality of the device.

[0069] However, the hot water tank assembly 20 will release a considerable amount of heat during operation. Due to the limitations of the internal structure design and space layout of the device, the interval between the hot water tank and the filtration system 50 is often small. In this way, the heat dissipated by the hot water tank will inevitably spread around and then have a radiation effect on the adjacent filtration system 50.

[0070] To solve the above problems, please refer to Figures 2 to 4, in the embodiment of the present application, the integrated water purification and heating device 1 further includes a heat insulation member 70, which is disposed inside the housing assembly 10 and divides the cavity 10a of the housing assembly 10 into a filter element cavity 104 and a hot water tank cavity 103. The filtration system 50 is located in the filter element cavity 104, and the hot water tank assembly 20 is located in the hot water tank cavity 103.

[0071] Based on the above embodiment, by setting the heat insulation member 70 to divide the cavity 10a of the housing assembly 10 into the filter element cavity 104 and the hot water tank cavity 103, on the one hand, it effectively blocks a large amount of heat generated during the operation of the hot water tank assembly 20 from radiating to the filtration system 50, avoiding the problems of accelerated aging of the filter material, reduced filtration efficiency and accuracy caused by heat radiation, ensuring that the filtration system 50 can maintain high filtration performance stably for a long time, and thus continuously and stably providing clean and safe drinking water for users. On the other hand, due to the heat insulation effect of the heat insulation member 70 on the hot water tank assembly 20, the temperature influence of heat on the normal temperature water is weakened, so that the normal temperature water can be maintained within a suitable temperature range, ensuring the user's demand for the quality of the normal temperature water and avoiding problems such as water quality change and taste change caused by the increase in the temperature of the normal temperature water. At the same time, it prevents the deformation and damage of the internal sealing material of the filtration system 50 and the interference of sensitive electronic components or sensors caused by high temperature, reduces the occurrence probability of equipment leakage faults, improves the overall operation stability and safety of the equipment, reduces the user's usage cost and maintenance frequency, and brings a more reliable and convenient usage experience to the user.

[0072] Refer to Figures 3 to 5, in some structural forms, the housing assembly 10 includes an outer shell 10A and a middle shell 12. The outer shell 10A is framed around the outer periphery of the middle shell 12. Both the filtration system 50 and the hot water tank assembly 20 are connected to the middle shell 12. As the outermost protective structure, the outer shell 10A can effectively resist adverse factors such as external collisions, dust, and water vapor, providing a first strong line of defense for the internal precision water purification components. It greatly reduces the risk of damage to the equipment caused by accidental collisions or harsh environmental factors during daily use, thereby extending the overall service life of the equipment and reducing the trouble and cost for users to frequently repair or replace the equipment. The outer shell 10A and the middle shell 12 are fixed by means of screws or buckles, etc., to ensure a tight combination, maintain the stability and protection of the overall structure, and ensure that the internal components are not interfered by external factors. It should be noted that the outer shell 10A may include a front panel 11, a back panel 13, a top panel 14, side panels 16, and a bottom panel 15. The front panel 11 is located on the front of the integrated water purifier and hot water dispenser 1, and is provided with components such as an operation interface and indicator lights. Of course, the control interface of the water purification device 1 can be installed on the faucet 2 or controlled through a mobile phone control terminal. The back panel 13 is located at the rear of the integrated water purifier and hot water dispenser 1 and is closely connected to the side panels 16, and is used to enclose the rear of the integrated water purifier and hot water dispenser 1. The top panel 14 is at the top of the device, and the side panels 16 surround both sides of the integrated water purifier and hot water dispenser 1 and are seamlessly connected to other panels. The bottom panel 15 bears the weight of the integrated water purifier and hot water dispenser 1 and isolates the influence of the ground.

[0073] The middle shell 12, on the other hand, plays the role of connecting and fixing the internal key components. By stably connecting the filtration system 50 and the hot water tank assembly 20 together, a closely coordinated whole is formed. This centralized connection method makes the relative positions of the components more accurate and stable, optimizes the internal water flow path and connection layout, reduces problems such as water leakage, seepage, and poor water flow caused by component loosening or displacement, and ensures the efficiency and stability of the water purification process. Moreover, when maintenance or repair of the equipment is required, maintenance personnel can more conveniently operate on the components connected to the middle shell 12 without having to search for and handle each component in a complex and chaotic structure, improving the repair efficiency, reducing the maintenance difficulty, and providing users with a more reliable and convenient use experience of the integrated water purifier and hot water dispenser 1.

[0074] Refer to Figure 3 and Figure 4, and the heat insulation member 70 includes a heat insulation cover 71 which is detachably connected to the middle shell 12 and encloses a hot water tank cavity 103 with the middle shell 12. The heat insulation cover 71 can effectively reduce the heat dissipation of the hot water tank assembly 20 to the surrounding environment and improve the utilization efficiency of heat. Compared with the traditional coating type heat insulation material on the hot water tank assembly 20, the heat insulation cover 71 has better integrity and stability. The coating type heat insulation material may crack, peel off, etc. over time, thus reducing the heat insulation effect. However, the heat insulation cover 71, as an independent structural component, can always maintain complete heat insulation performance, effectively block the heat dissipation of the hot water tank assembly 20 to the surrounding environment, and improve the utilization efficiency of heat. At the same time, compared with some embedded heat insulation structures, the detachable characteristic of the heat insulation cover 71 provides great convenience for maintenance personnel. When the hot water tank assembly 20 fails and needs to be repaired or replaced, the maintenance operation of the embedded heat insulation structure is often extremely complex, and a large number of surrounding components may need to be removed to reach the hot water tank assembly 20. However, the heat insulation cover 71 can be easily detached from the middle shell 12, and the hot water tank assembly 20 can be directly operated without difficultly searching for and dealing with faulty components in the complex heat insulation structure, greatly shortening the maintenance time and downtime, and improving the availability and maintenance efficiency of the equipment.

[0075] Furthermore, the integrated net heat machine 1 further includes a water circuit board 60. The filtration system 50 and the hot water tank assembly 20 are connected through the water circuit board 60. The water circuit board 60 is connected to the middle shell 12 and is located in the filtration cavity 104.

[0076] Among them, the water circuit board 60 is used to provide a water flow channel so that the pure water filtered by the filtration system 50 can flow to the hot water tank assembly 20 for heating. Compared with the traditional method of using separate water pipes to connect each component, this design greatly reduces the number of separate water pipes. This not only simplifies the pipeline layout inside the equipment, makes the internal structure of the equipment more compact and concise, reduces the space occupied by the intersection of numerous water pipes, and improves the overall space utilization rate of the equipment. At the same time, the water flow channel of the water circuit board 60 can also discharge the filtered waste water. By arranging the water circuit board 60 inside the housing assembly 10, the protective performance of the housing assembly 10 is fully utilized to protect the water circuit board 60. And multiple water flow channels can be provided inside the water circuit board 60, which is more convenient and fast to install compared with the traditional decentralized water pipe connection. In terms of the material of the water circuit board 60, a high-strength and corrosion-resistant composite material is selected. This material not only has excellent chemical erosion resistance and can effectively resist the corrosion of various acid-base substances that may exist in the water to the water circuit board 60, but also its unique molecular structure enables the water circuit board 60 to still maintain the integrity of the structure and the stability of the dimensions under the long-term action of water flow pressure and temperature changes, thus ensuring the smoothness of the water flow channel.

[0077] Furthermore, the water circuit board 60 includes a first water circuit board 61 and a second water circuit board 62 that are connected and communicate with each other. The filtration system 50 and the hot water tank assembly 20 are respectively located on opposite sides of the first water circuit board 61, and the second water circuit board 62 is disposed at an angle to the first water circuit board 61. Specifically, the second water circuit board 62 and the first water circuit board 61 can be disposed at a perpendicular 90-degree angle. This standardized 90-degree angle design facilitates mold development and standardization of the production process, reduces production costs and production cycles, and at the same time facilitates maintenance personnel to quickly locate and replace components of the water circuit board 60 when a malfunction occurs in the equipment, reducing maintenance time and costs. Of course, the angle between the first water circuit board 61 and the second water circuit board 62 can also be 70°, 80°, 100°, 110°, etc. Such a setting optimizes the internal space utilization and performance of the housing assembly 10, can be flexibly arranged according to the actual space form inside the housing assembly 10, effectively adapts to the installation positions of the filtration system 50 and the hot water tank assembly 20, avoids the problem of space waste caused by the limited structure of the traditional water circuit board 60, makes the connection between components more compact and efficient, reduces unnecessary pipeline length and complexity, reduces water flow resistance, thereby improving the water purification efficiency and water flow stability, reducing the risk of water leakage, and ensuring the reliable operation of the integrated water purification and heating machine 1.

[0078] In addition, the water circuit board 60 is located in the filtration chamber 104. This not only makes the water circuit board 60 closer to the filtration system 50, but also effectively isolates it from the hot water tank chamber 103, avoiding the adverse effect of the hot water tank assembly 20 on the normal temperature water in the water circuit board 60. In this way, the normal temperature water can be transmitted and subsequently purified in a stable temperature environment, ensuring that filtration, purification and other links can be carried out according to the expected standards and effects, improving the water purification quality and stability. At the same time, when it is necessary to inspect, clean or repair the water circuit board 60 or the filtration system 50, maintenance personnel can operate on the relevant components relatively concentratedly in the filtration chamber 104, without having to search and disassemble extensively inside the entire equipment, improving the efficiency and accuracy of the maintenance work, reducing the maintenance difficulty and costs.

[0079] With reference to Figure 6 , furthermore, the heat insulation cover 71 includes a cover main body 712 and an upper cover plate 711 and a lower cover plate 713 connected to opposite ends of the cover main body 712. The cover main body 712 is detachably connected to the water circuit board 60 or the middle shell 12. The cover main body 712 covers the side wall of the hot water tank assembly 20, the upper cover plate 711 extends to cover a part of the upper surface of the hot water tank assembly 20, and the lower cover plate 713 extends to cover a part of the lower surface of the hot water tank assembly 20.

[0080] Among them, the cover main body 712 closely covers the side wall of the hot water tank assembly 20, forming a solid heat insulation barrier, effectively blocking the heat dissipation from the side wall direction. The presence of the cover main body 712 can significantly reduce the heat transfer in this direction, limiting the heat as much as possible near the side wall of the hot water tank assembly 20. The upper cover plate 711 extends to cover a part of the upper surface of the hot water tank assembly 20, and this design further optimizes the heat insulation effect. The upper surface of the hot water tank assembly 20 is also an important way of heat dissipation. Especially under the action of natural convection, hot air will flow upward. Without the coverage of the upper cover plate 711, the heat will quickly dissipate into the space above the equipment, causing waste of energy and unnecessary increase in the surrounding environment temperature. The lower cover plate 713 extends to cover a part of the lower surface of the hot water tank assembly 20, and also plays a key role in suppressing heat dissipation. The lower surface of the hot water tank assembly 20 is in contact with the installation surface of the equipment or other supporting structures, and heat may be transferred to these components by conduction and then dissipated to the surrounding environment. The coverage of the lower cover plate 713 can effectively reduce this heat transfer, prevent the heat from spreading downward, and further strengthen the overall heat insulation performance of the heat insulation cover 71. In this way, through this all-round coverage, effective heat isolation is carried out on the upper, lower and side surfaces of the hot water tank assembly 20, greatly reducing the heat dissipation of the hot water tank assembly 20 to the surrounding environment, retaining the heat in the hot water tank assembly 20 as much as possible for heating water, improving the energy utilization efficiency, reducing the operation cost of the equipment, and enhancing the performance and stability of the equipment.

[0081] In addition, the integrated water and heat machine 1 further includes a water pump 30. The water pump 30 is arranged in the housing assembly 10 and communicated with the water circuit board 60. Thus, relying on the pumping performance of the water pump 30, the hot water in the hot water tank assembly 20 is pumped out and discharged through the water circuit board 60, so that the integrated water and heat machine 1 can provide efficient and stable water supply services, enabling users not to worry about affecting normal domestic water use due to insufficient water pressure or unstable water flow. And an inlet valve 63, a check valve 64, a waste water plug 65 and a make-up water valve 66 can also be installed on the water circuit board 60. The inlet valve 63 is used to control the conduction of the water path entering the filtration system 50 on the water circuit board 60. The check valve 64 is located between the filtration system 50 and the hot water tank assembly 20 to prevent the filtered water flow from flowing back. With reference to Figure 7 , thus the water flow path of this application is as follows: Tap water first flows into the water circuit board 60 from the interface of the water circuit board 60, and then passes through the primary filter element 51 to complete the primary filtration. Subsequently, driven by the booster pump 53, the water flow passes through the secondary filter element 52 for secondary filtration. The waste water after two-stage filtration will be discharged through the waste water plug 65, while the pure water will be split into two paths through the check valve 64. One path can supply an external pipeline machine 3 to directly output normal temperature water; the other path, after the make-up water valve 66 is opened, flows to the hot water tank assembly 20 and becomes hot water under the heating action of the hot water tank assembly 20.

[0082] In addition, the integrated water purifier and water heater may further include a faucet 2. The faucet 2 is connected to the housing assembly 10 and communicates with the hot water tank assembly 20 and the filtration system 50. When the faucet 2 is opened, hot water in the hot water tank assembly 20 or normal temperature water in the filtration system 50 can flow out through the faucet 2 to provide hot water or normal temperature water for the user. It can be understood that the integrated water purifier 1 may have two faucets 2, one faucet 2 communicates with the hot water tank assembly 20, and the other faucet 2 communicates with the filtration system 50, so that hot water and normal temperature water can be provided for the user separately. In other embodiments, the faucet 2 may also communicate with the hot water tank assembly 20 and the filtration system 50 respectively, and the switch is used to control the faucet 2 to flow out hot water or normal temperature water.

[0083] It can be understood that the faucet 2 may also be an intelligent faucet 2. When the controller detects a signal for taking normal temperature water at the intelligent faucet 2 or a water replenishment signal for the hot water tank assembly 20, the controller can control the filtration system 50 to start water production to ensure that the user can obtain normal temperature water and hot water from the intelligent faucet 2 in time, reduce the waiting time of the user, and improve the user experience.

[0084] The hot water tank assembly 20 communicates with the faucet 2 and the filtration system 50, can heat the normal temperature water filtered by the filtration system 50, and provide hot water for the user after the faucet 2 is opened.

[0085] It can be understood that the faucet 2 can also be installed near the operation panel and communicate with the hot water tank assembly 20 and the filtration system 50 through pipelines, so that the user can control the water outlet of the faucet 2 through the operation panel, and further facilitate the user to obtain hot water and normal temperature water from the faucet 2.

[0086] In addition, the integrated water purifier 1 of the present application can also realize the function of the user obtaining water at a set temperature, that is, the user can also obtain the function of warm water at a temperature between the normal temperature water and the hot water discharged from the hot water tank assembly 20 from the faucet 2. For this reason, the integrated water purifier 1 of the present application may further include a first temperature sensor and a second temperature sensor. The first temperature sensor is connected to the tank body 21 and is arranged in the heating cavity 21A for detecting the temperature of the hot water in the heating cavity 21A. The second temperature sensor is arranged in the pure water pipeline for detecting the normal temperature of the normal temperature water in the pure water pipeline. Both the first temperature sensor and the second temperature sensor are connected to the controller. The controller can receive the detection values of the first temperature sensor and the second temperature sensor and control the operating power of the water pump 30 and the booster pump 53 to form warm water at a set temperature value at the faucet 2. It can be understood that the first temperature sensor can also be arranged in the water outlet pipe of the tank body 21 to detect the hot water temperature of the water outlet pipe of the tank body 21.

[0087] It can be understood that a warm water control device can be provided on the operation panel, and the warm water control device includes at least one of a button, a knob, a touch screen, etc. The user can operate the warm water control device to select the required warm water temperature, so that the faucet 2 can discharge warm water of the user-selected temperature to meet the user's needs.

[0088] In the embodiments of the present application, the selection of warm water at 45° C. and warm water at 55° C. is taken as an example to explain the specific method steps.

[0089] When the user selects warm water temperature through the warm water control device, the controller obtains the temperature selection signal of the warm water; if the temperature selection signal is a 45°C warm water signal, the controller controls the boost pump 53 to adjust the duty cycle to 85%, the controller obtains the current room temperature water temperature through the first temperature sensor, and obtains the current hot water temperature through the second temperature sensor, and calculates the first output duty cycle of the water pump 30 according to the first preset formula, and the controller adjusts the output duty cycle of the water pump 30 according to the first output duty cycle value. At this time, 45°C warm water can flow out of the water outlet of the faucet 2; when the controller detects that the water level of the tank 21 drops to a low water level, or when the controller receives a closing signal of the faucet 2, the controller controls the water outlet of the faucet 2 to stop draining water.

[0090] If the temperature selection signal is not a 45°C warm water signal, it indicates that the user selects 55°C warm water. The controller controls the boost pump 53 to adjust the duty cycle to 75%. The controller obtains the current room temperature water temperature through the first temperature sensor, and obtains the current hot water temperature through the second temperature sensor. The second output duty cycle of the water pump 30 is calculated according to the second preset formula. The controller adjusts the output duty cycle of the water pump 30 according to the second output duty cycle value. At this time, 55°C warm water can flow out of the water outlet of the faucet 2; when the controller detects that the water level of the tank 21 drops to a low water level, or when the controller receives a closing signal of the faucet 2, the controller controls the water outlet of the faucet 2 to stop draining water.

[0091] It is understandable that in other embodiments, the operation panel may also provide other warm water temperature options, such as 35°C, 50°C, and 60°C, etc. In the embodiments of the present application, no specific limitation is made to this.

[0092] Optionally, the heat insulation member 70 further includes heat insulation cotton (not shown), and the heat insulation cotton is attached to one side of the water channel plate 60 facing the hot water tank assembly 20. Among them, the heat insulation cotton, as a material with excellent heat insulation performance, can effectively inhibit the heat transfer path at the microscopic level. The close attachment of the heat insulation cotton greatly slows down the rate and intensity of heat conduction from the hot water tank assembly 20 to the water channel plate 60. It effectively maintains the relatively stable temperature of the water channel plate 60, avoids the abnormal increase in the temperature of the normal temperature water in the water channel plate 60 due to excessive heat conduction, thereby ensuring that the water can maintain its original physical and chemical properties when passing through the water channel plate 60, guaranteeing the normal operation and high efficiency of the subsequent water purification process, and improving the stability and reliability of the entire water purification system.

[0093] Referring to Figure 4 , Figure 5 and Figure 8 , in some embodiments, the middle shell 12 includes a base plate 121, a water channel plate support seat 122, and a filter support seat 123. The base plate 121 includes an installation surface and an abutting surface arranged oppositely, and the abutting surface is fixedly abutted against the inner wall of the outer shell 10A, and the hot water tank assembly 20 is connected to the installation surface. Among them, the base plate 121, as a basic component, its oppositely arranged installation surface and abutting surface play a key role. The abutting surface is tightly abutted and fixed to the inner wall of the outer shell 10A, forming a stable connection structure, effectively enhancing the compressive resistance of the entire housing assembly 10, so that when the integrated water purifier and heater 1 is subjected to external pressure or collision, it can better protect the internal components from damage, thereby extending the service life of the integrated water purifier and heater 1 and reducing the maintenance cost and replacement frequency caused by the failure of the integrated water purifier and heater 1 for users. The hot water tank assembly 20 can be fixed to the installation surface by means of screws or snap connections.

[0094] The water channel plate support seat 122 is connected to the installation surface, and the water channel plate 60 is connected to the water channel plate support seat 122. After the water channel plate 60 is connected to the water channel plate support seat 122, it can maintain a stable working state and avoid displacement or deformation due to its own weight or water flow impact. The stable water channel plate 60 can ensure the smoothness of the internal flow channel, reduce the water flow resistance, improve the water transmission efficiency, make the water purification process more efficient and fast, and meet the user's demand for stable water supply. Moreover, the accurate support and positioning help to improve the connection accuracy between the water channel plate 60 and other components, further reduce the risk of water leakage, and ensure the sealing and reliability of the entire water purification system.

[0095] The filter support base 123 is connected to the mounting surface and is spaced apart from the water circuit board support base 122. The filtration system 50 is connected to the filter support base 123. This provides a dedicated mounting position for the filtration system 50. After the filtration system 50 is connected to the filter support base 123, it can operate in a relatively stable and independent space, reducing interference from external factors during the filtration process and ensuring the stability and reliability of the filtration effect. At the same time, the spaced-apart structure is conducive to optimizing the internal space layout of the device, making the connections between components more reasonable and compact, facilitating the installation, maintenance, and repair of the device. Maintenance personnel can more conveniently perform operations such as filter element replacement and cleaning on the filtration system 50, reducing the maintenance difficulty and cost and improving the maintainability of the device.

[0096] The above settings enable the water circuit board 60, the filtration system 50, and the hot water tank assembly 20 to be all located on one side of the mounting surface of the base plate 121. From the perspective of the convenience of production and assembly, concentrating these key components on the same side of the mounting surface of the base plate 121 allows workers to sequentially and orderly complete the installation of components such as the water circuit board 60, the filtration system 50, and the hot water tank assembly 20 at a relatively fixed position and direction without complex flipping operations, greatly shortening the assembly time, reducing the labor input, and improving the production efficiency. In terms of the overall stability and reliability of the device, this same-side layout also plays an important role. Since the relative positions between components such as the water circuit board 60, the filtration system 50, and the hot water tank assembly 20 are closer and more stable after installation, problems such as connection loosening and displacement that may occur due to components being distributed on different sides are reduced.

[0097] Furthermore, the middle shell 12 further includes a baffle 124. The baffle 124 is connected to the edge of the mounting surface. The water circuit board support base 122, the filter support base 123, the base plate 121, and several baffles 124 enclose a cavity 10a. From the overall structure of the device, the presence of the baffle 124 further improves the structural integrity of the middle shell 12 and enhances the protection ability for internal components. It can effectively block external dust, water vapor, and other possible impurities from entering the cavity 10a. Due to the space formed by the close enclosure of each component, interference from external factors to the hot water tank assembly 20 and the water circuit board 60 is reduced. In addition, when maintenance or repair of the device is required, the presence of the cavity 10a enables maintenance personnel to more clearly locate and operate the hot water tank assembly 20, the water circuit board 60, and their related components. Compared with devices with an open or loose structure, the enclosed cavity 10a reduces the difficulty of component search and fault troubleshooting, improves the maintenance efficiency, and reduces the maintenance cost and time.

[0098] Furthermore, the enclosure 124, the substrate 121, the filter support base 123, and the water circuit board support base 122 are an integral member. Such an integrated design greatly enhances the overall strength and rigidity of the middle shell 12. There are no connection gaps or weak points between the parts, enabling the middle shell 12 to more firmly bear the weights of the internal water tank, the water circuit board 60, and the filter system 50, as well as external impact forces and vibrations, effectively preventing component deformation, displacement, or damage caused by long-term use or accidental collisions, ensuring the stable operation of the precision components inside the device, reducing the probability of equipment failures, and extending the service life of the device.

[0099] With reference to Figure 3 and Figure 5 , optionally, the filter support base 123 and the water circuit board support base 122 are arranged in sequence along the front-rear direction of the outer shell 10A, and the hot water tank assembly 20 is located on the side of the water circuit board support base 122 away from the filter support base 123. Thus, arranging the filter support base 123 away from the hot water tank assembly 20 can effectively reduce the high-temperature influence of the hot water tank assembly 20 on the filter system 50. Since the hot water tank assembly 20 generates heat during operation, if it is too close to the filter system 50, the high-temperature environment may have a negative impact on the performance of the filter material. By keeping a certain distance between the filter support base 123 and the hot water tank assembly 20, the filter system 50 can be in a relatively stable and suitable temperature environment, ensuring the stable performance of the filter material, maintaining an efficient filtering effect, extending the overall service life of the filter system 50, reducing the user's usage cost and maintenance cost, and enhancing the reliability and durability of the product.

[0100] Refer to Figure 4 and Figure 5, optionally, an installation cavity 1231 is provided in the filter support base 123, and an installation opening 1232 communicating with the installation cavity 1231 is formed on the side of the filter support base 123 facing away from the water circuit board support base 122. The installation opening 1232 is used for the filter system 50 to pass through and be installed in the installation cavity 1231. It can be understood that when the filter element passes through the installation opening 1232 and is fixed in the installation cavity 1231, the filter element and the filter support base 123 form a tightly combined integral structure. In this way, it can effectively prevent the filter element from being displaced, loosened or even damaged due to water flow impact, equipment vibration or other external factors, thus ensuring the stability and reliability of the filter system 50 and enabling the filtering process to proceed continuously and efficiently. From the perspective of long-term use, the stable filter element installation method reduces the risk of wear and leakage of the filtering medium caused by frequent shaking or displacement of the filter element, extends the service life of the filter element, and reduces the frequency and cost of users replacing the filter element. At the same time, the stable filtering process also ensures the stability of the purified water quality, provides a solid foundation for the stable operation of the subsequent water circuit board 60 and the entire water purification and heating integrated machine 1, reduces the potential damage to other components of the equipment caused by water quality fluctuations, reduces the overall repair rate and maintenance cost of the equipment, and improves the durability and performance stability of the equipment. In addition, an avoidance hole is formed at one end of the filter support base 123 facing away from the installation opening 1232. The avoidance hole is used for the filter element to communicate with the water circuit board 60. The existence of the avoidance hole optimizes the connection structure between the filter element and the water circuit board 60. Compared with complex or indirect connection methods, it reduces possible fault points such as connection looseness and water leakage, making the connection between the filter element and the water circuit board 60 tighter and more stable.

[0101] It should be noted that when the filter system 50 includes a primary filter element 51 and a secondary filter element 52, the two corresponding installation cavities 1231 on the filter support base 123 further optimize the installation and management of the filter element. This design enables filter elements with different functions to be installed and operate in their respective independent and adapted spaces, avoiding possible mutual interference and influence between different filter elements, ensuring that each filter element can fully exert its due filtering efficiency, and improving the filtering accuracy and efficiency of the entire filter system 50.

[0102] Furthermore, the waterway board support base 122 includes a base body 1221 and a limiting plate 1222. The base body 1221 is connected to the installation surface, and the limiting plate 1222 is connected to the side of the base body 1221 facing away from the installation surface. The waterway board 60 is detachably connected to the base body 1221, and the surface of the waterway board 60 facing the hot water tank assembly 20 abuts against the limiting plate 1222. Among them, the characteristic that the waterway board 60 is detachably connected to the base body 1221 greatly optimizes the maintenance and repair process of the equipment. When the waterway board 60 is blocked, leaks, or has other faults, maintenance personnel can quickly and conveniently detach it from the base body 1221 for targeted inspection, cleaning, or component replacement operations, without the need to perform complex disassembly of the entire equipment, which not only significantly shortens the maintenance time but also reduces the downtime. Secondly, the presence of the limiting plate 1222 can accurately control the safety distance between the waterway board 60 and the hot water tank assembly 20, preventing the waterway board 60 from being too close to the hot water tank assembly 20 due to various factors after installation. Through the effective constraint of the position of the waterway board 60 by the limiting plate 1222, it is ensured that the normal temperature water can maintain a stable and appropriate temperature state in the waterway, enabling various physical and chemical properties of the water to be maintained at normal levels, thus ensuring that subsequent filtration, purification, and other links can proceed according to the expected standards and effects, improving the quality and stability of the purified water.

[0103] Referring to Figure 8 , optionally, the middle shell 12 further includes a support member 126. The support member 126 is connected to the filter support base 123. The integrated water purification and heating machine 1 further includes a control board 80. The control board 80 is fixed to the side of the support member 126 facing away from the installation surface and is located in the filter cavity 104. The control board 80 is electrically connected to the hot water tank assembly 20. From the perspective of the overall layout and stability of the equipment, the support member 126, as a key component connecting the filter support base 123 and the enclosure 124, enhances the integrity and rigidity of the internal structure of the middle shell 12. It can effectively disperse and bear various stresses generated during the operation of the equipment. Whether it is the force caused by water flow impact, thermal expansion and contraction, or external vibration and other factors, it can be reasonably distributed and buffered through the support member 126, thereby ensuring the relative positions of the filter support base 123, the enclosure 124, and other internal components remain stable.

[0104] The hot water tank assembly 20 will be described in detail below.

[0105] Please refer to Figures 9 to 11, the hot water tank assembly 20 may include a water tank body 21 and a heating element 22. The water tank body 21 has a heating chamber 21a which can be used to hold liquid; the heating element 22 is connected to the water tank body 21 to heat the liquid in the heating chamber 21a. It can be understood that the heating element 22 can be installed on or near the outer wall surface of the water tank body 21 to transfer heat to the liquid in the heating chamber 21a by heat conduction, so that the liquid in the heating chamber 21a can be heated; alternatively, the heating element 22 is installed in the heating chamber 21a and connected to the water tank body 21. In this way, the heating element 22 can directly heat the liquid in the heating chamber 21a. The embodiments of the present application do not make specific limitations on this.

[0106] Wherein, when the heating element 22 is located in the heating chamber 21a, the terminal 221 of the heating element 22 can penetrate through the water tank body 21 so that the terminal 221 extends out of the outer wall surface of the water tank body 21, facilitating the electrical connection between the control board 80 and the terminal 221, thereby facilitating the control board 80 to control the operation of the heating element 22 according to the set program, so as to heat the liquid in the heating chamber 21a.

[0107] Please refer to Figure 9 and Figure 11 , the hot water tank assembly 20 further includes an exhaust pipe 24, and the exhaust pipe 24 is connected to the water tank body 21 and communicates with the heating chamber 21a. It can be understood that when the heating element 22 works, it will heat the liquid in the heating chamber 21a, so that part of the water in the heating chamber 21a is converted into water vapor, resulting in an increase in the internal pressure of the heating chamber 21a. If the water vapor in the heating chamber 21a cannot be discharged in time, it may cause the internal pressure of the hot water tank assembly 20 to be too high, leading to potential safety hazards such as the rupture or leakage of the hot water tank assembly 20. Therefore, the embodiments of the present application provide an exhaust pipe 24 communicating with the heating chamber 21a, and the exhaust pipe 24 can be used to discharge the water vapor generated during the heating of the liquid in the heating chamber 21a to ensure the safety of the use of the water tank body 21. In addition, after the water vapor in the heating chamber 21a is discharged from the exhaust pipe 24, the air content in the heating chamber 21a can be reduced, so that the heat acts more concentratedly on the water molecules, thereby improving the heating efficiency of the water tank body 21.

[0108] The material of the exhaust pipe 24 may include silicone; that is, due to its excellent high temperature resistance, corrosion resistance and flexibility, the silicone material is widely used in the exhaust pipe 24 of the water dispenser. It can not only withstand the impact of the high temperature water vapor inside the water tank body 21, and is not easily deformed or damaged, but also adapt to the complex structural layout inside the integrated water purifier and heater 1 to ensure tight connection and no air leakage. In addition, the silicone material is non-toxic and odorless, meeting the food safety standards.

[0109] The hot water tank assembly 20 further includes a condensate pipe 28 which has a condensate chamber 281 capable of holding cooling water, and a part of the exhaust pipe 24 passes through the condensate chamber 281 such that a part of the exhaust pipe 24 is located within the condensate chamber 281. Thus, when the water vapor within the exhaust pipe 24 flows through the condensate chamber 281, it can be cooled by the cooling water and condensed. At this time, the water vapor flowing through the condensate chamber 281 will be condensed into water droplets, and under the action of gravity, the water droplets will flow back from the exhaust pipe 24 into the heating chamber 21a. That is to say, by extending a part of the exhaust pipe 24 into the condensate chamber 281 of the condensate pipe 28, the cooling water within the condensate chamber 281 can condense the water vapor flowing through the condensate chamber 281, thereby condensing the water vapor into water droplets. In this way, it is possible to prevent the water vapor from spraying out of the faucet 2, preventing high-temperature water vapor from scalding the user, and thus improving the safety of using the integrated water purifier and water heater 1. Moreover, since the water vapor within the exhaust pipe 24 can be cooled and condensed by the cooling water when flowing through the condensate chamber 281, the water vapor will be condensed into water droplets, and under the action of gravity, the water droplets will flow back from the exhaust pipe 24 into the heating chamber 21a. In this way, it is possible to prevent the faucet 2 from dripping water, reducing the waste of water sources. The material of the condensate pipe 28 can include stainless steel, copper, aluminum, etc., and the embodiments of the present application do not specifically limit the material of the condensate pipe 28.

[0110] In the embodiments of the present application, by arranging a part of the exhaust pipe 24 to pass through the condensate chamber 281 of the condensate pipe 28, in this way, when the water vapor in the exhaust pipe 24 flows through the condensate chamber 281, the water vapor will be cooled and condensed into water droplets by the cooling water in the condensate chamber 281. In this way, the water droplets will flow back into the heating chamber 21a under the action of gravity to prevent the faucet 2 from dripping water, and at the same time, it is possible to prevent the water vapor from coming out of the faucet 2 to avoid high-temperature water vapor from scalding the user. In this way, the safety of using the integrated water purifier and water heater 1 is improved.

[0111] It should be noted that the embodiments of the present application do not specifically limit the type of the heating element 22. Exemplarily, the heating element 22 can be an electric heating wire heating element 22, a positive temperature coefficient (PTC) ceramic sheet heating element 22, etc. The electric heating wire heating element 22 utilizes the thermal effect of the current to convert electrical energy into heat energy to heat the liquid in the heating chamber 21a; the PTC ceramic sheet heating element 22 utilizes the constant temperature heating characteristic of the PTC thermistor to achieve heating the liquid in the heating chamber 21a at a constant temperature.

[0112] Please refer to Figure 11 , in some embodiments, the condensate pipe 28 has a water inlet 282 and a water outlet 283, both the water inlet 282 and the water outlet 283 are communicated with the condensate chamber 281, and the water inlet 282 is used for connecting the cooling water.

[0113] Further, the hot water tank assembly 20 further includes a water inlet pipe 25. One end of the water inlet pipe 25 is connected to the tank body 21 and communicates with the heating cavity 21a. The other end of the water inlet pipe 25 is connected to the condensation pipe 28 and communicates with the water outlet 283. It can be understood that, for the convenience of injecting liquid into the heating cavity 21a, the hot water tank assembly 20 is also provided with a water inlet pipe 25 connected to the tank body 21. One end of the water inlet pipe 25 communicates with the heating cavity 21a, and the other end of the water inlet pipe 25 communicates with the water outlet 283. In this way, when the tank body 21 needs to be replenished with water, the cooling water enters the condensation cavity 281 from the water inlet 282, and then the cooling water flows into the heating cavity 21a from the water outlet 283 and via the water inlet pipe 25, so as to replenish the heating cavity 21a with water.

[0114] Furthermore, since the other end of the water inlet pipe 25 communicates with the water outlet 283, and the water outlet 283 communicates with the condensation cavity 281, after the heating cavity 21a is replenished with water, the control board 80 controls the heating element 22 to heat. After the heating element 22 heats the cooling water in the heating cavity 21a for a period of time, water vapor is generated in the heating cavity 21a, and the water vapor is discharged from the exhaust pipe 24. At this time, a part of the exhaust pipe 24 is located in the condensation cavity 281, and the condensation cavity 281 is filled with cooling water, so as to facilitate the condensation of the cooling water on the water vapor flowing through the condensation cavity 281 and in the exhaust pipe 24, so as to prevent the water vapor from spraying out from the faucet 2.

[0115] It should be noted that the cooling water remaining in the condensation cavity 281 last time will flow due to the flow, and will flow into the heating cavity 21a through the water outlet 283 and the water inlet pipe 25 when the heating cavity 21a is replenished with water next time. In this way, the cooling water in the condensation cavity 281 is replaced to ensure the durability of the condensation effect of the condensation cavity 281.

[0116] In some embodiments, in the width direction of the condensation pipe 28, the water inlet 282 and the water outlet 283 are located on the same side or different sides of the condensation pipe 28, and in the height direction of the condensation pipe 28, the height of the water outlet 283 is higher than the height of the water inlet 282. It can be understood that, in the height direction of the condensation pipe 28, the position of the water outlet 283 on the condensation pipe 28 needs to be higher than the position of the water inlet 282, so that part of the cooling water entering from the water inlet 282 can be retained in the condensation cavity 281, so as to facilitate part of the exhaust pipe 24 to be immersed in the cooling water, thereby improving the condensation effect of the condensation pipe 28.

[0117] It should be noted that in the height direction of the condensation pipe 28, the height from the position of the water inlet 282 on the condensation pipe 28 to the position of the water outlet 283 is not specifically limited. And the width direction of the condensation pipe 28 and the height direction of the condensation pipe 28 are perpendicular to each other.

[0118] In some other embodiments, in the height direction of the condenser tube 28, the water inlet 282 is arranged at the bottom of the condenser tube 28, and the water outlet 283 is arranged at the top of the condenser tube 28. It can be understood that the water inlet 282 can be arranged at the topmost part of the condenser tube 28, and the water outlet 283 is arranged at the topmost part of the condenser tube 28, so as to facilitate more cooling water to be retained in the condensation chamber 281, thereby facilitating partial immersion of the exhaust pipe 24 in the cooling water, and thus improving the condensation effect of the condenser tube 28.

[0119] Please refer to Figures 12 - 14 , in some embodiments, in the height direction of the hot water tank assembly 20, the height of the water inlet pipe 25 is lower than the height of the exhaust pipe 24. It can be understood that since a part of the exhaust pipe 24 penetrates through the condensation chamber 281, and the other end of the water inlet pipe 25 is communicated with the water outlet 283, and the water outlet 283 is communicated with the condensation chamber 281, so by setting the height of the water inlet pipe 25 lower than the height of the exhaust pipe 24, the water inlet pipe 25 is closer to the tank body 21. In this way, on the one hand, the water replenishment efficiency of the heating chamber 21a can be improved, and on the other hand, the height of the other end of the water inlet pipe 25 is lower than the end of the exhaust pipe 24 far from the tank body 21. In this way, when the condensation chamber 281 is filled with cooling water, the cooling water in the condensation chamber 281 will only flow into the water inlet pipe 25 from the water outlet 283, and will not flow in from the end of the exhaust pipe 24 far from the tank body 21, so as to prevent the cooling water in the condensation chamber 281 from flowing into the heating chamber 21a through the exhaust pipe 24.

[0120] It should be noted that the height direction of the above-mentioned hot water tank assembly 20 can be understood as the height direction of the condenser tube 28.

[0121] Please refer to Figure 11 and Figure 13 , in some embodiments, the condenser tube 28 includes a condensation section 284, and the condensation section 284 has a first condensation opening 2841 and a second condensation opening 2842. It can be understood that a condensation chamber 281 can be formed inside the condensation section 284, and the condensation chamber 281 is communicated with both the first condensation opening 2841 and the second condensation opening 2842, so as to facilitate the exhaust pipe 24 to pass through the condensation chamber 281 from the first condensation opening 2841 and then pass out from the second condensation opening 2842, so that a part of the exhaust pipe 24 is located in the condensation chamber 281, thereby facilitating the cooling water in the condensation chamber 281 to condense the water vapor in the exhaust pipe 24 flowing through the condensation chamber 281.

[0122] Furthermore, after a part of the exhaust pipe 24 penetrates through the condensation section 284, the exhaust pipe 24 needs to be sealed with the first condensation opening 2841 and the second condensation opening 2842. On the one hand, it can achieve water-vapor separation, and on the other hand, it can prevent the cooling water in the condensation chamber 281 from flowing out of the condenser tube 28 from the first condensation opening 2841 or the second condensation opening 2842.

[0123] Please continue to refer to Figure 11 and Figure 13 , further, in some embodiments, the condenser tube 28 further includes a support tube section 285. One end of the support tube section 285 is connected to the end of the condensation section 284 close to the tank body 21. The support tube section 285 communicates with the first condensation opening 2841, so that the exhaust pipe 24 passes through the support tube section 285 and extends into the condensation chamber 281; and one end of the support tube section 285 abuts against the tank body 21 to facilitate the support of the condensation section 284.

[0124] Please continue to refer to Figure 11 and Figure 13 , furthermore, in some embodiments, the condenser tube 28 further includes an air outlet tube section 286. One end of the air outlet tube section 286 is connected to the end of the condensation section 284 away from the tank body 21. The other end of the air outlet tube section 286 is connected to the faucet 2. The air outlet tube section 286 communicates with the second condensation opening 2842, so that the end of the exhaust pipe 24 away from the tank body 21 extends into the air outlet tube section 286 through the second condensation opening 2842, thereby realizing that a part of the exhaust pipe 24 extends into the air outlet tube section 286.

[0125] It should be noted that the embodiments of the present application do not specifically limit the connection manner of the condensation section 284, the support tube section 285 and the air outlet tube section 286.

[0126] Please continue to refer to Figure 11 and Figure 13 , exemplarily, the condensation section 284, the support tube section 285 and the air outlet tube section 286 are integral components; that is, the condensation section 284, the support tube section 285 and the air outlet tube section 286 can be integrally formed by one injection molding. In this way, on the one hand, it is convenient for a part of the exhaust pipe 24 to extend into the condenser tube 28, and on the other hand, it can improve the connection stability and sealing performance of the condensation section 284, the support tube section 285 and the air outlet tube section 286 to prevent the cooling water in the condensation chamber 281 from flowing out of the condenser tube 28.

[0127] Exemplarily, the condensation section 284, the support tube section 285 and the air outlet tube section 286 are all connected by welding to realize the connection between the end of the condensation section 284 close to the tank body 21 and the support tube section 285, and the connection between the end of the condensation section 284 away from the tank body 21 and the air outlet tube section 286.

[0128] After a part of the exhaust pipe 24 extends into the air outlet pipe section 286, in order to achieve the sealed connection of both the support pipe section 285 and the air outlet pipe section 286 with the part of the exhaust pipe 24, thus, in some embodiments, both the support pipe section 285 and the air outlet pipe section 286 are in close fit with the exhaust pipe 24; that is, the inner diameters of the support pipe section 285 and the air outlet pipe section 286 are equal to the outer diameter of the exhaust pipe 24, so that the outer wall of the exhaust pipe 24 is in sealed fit with the inner walls of the support pipe section 285 and the air outlet pipe section 286 respectively, thereby improving the sealing performance of the connection between the exhaust pipe 24 and the support pipe section 285 and the air outlet pipe section 286. In this way, it is possible to prevent the cooling water in the condensation chamber 281 from flowing out of the condensation pipe 28 and to achieve water-vapor separation. Of course, in other embodiments, the support pipe section 285 and the air outlet pipe section 286 can be hermetically connected to the part of the exhaust pipe 24 through a silicone seal.

[0129] Please refer to Figure 15 , in some embodiments, the tank body 21 includes a tank body 211, a tank top cover 212 and a tank bottom cover 213.

[0130] Specifically, the material of the tank body 21 is usually made of food-grade stainless steel to ensure the safety and hygiene of the liquid. These materials have the characteristics of stable structure, high temperature resistance and not easy to rust to meet the use requirements of the tank body 21. The tank top cover 212 is connected to the top of the tank body 211, and the tank bottom cover 213 is connected to the bottom of the tank body 211; that is, the tank top cover 212, the tank body 211 and the tank bottom cover 213 can be connected by welding, screwing and other methods to achieve the sealed connection of the tank top cover 212, the tank body 211 and the tank bottom cover 213, and the tank bottom cover 213, the tank body 211 and the tank top cover 212 enclose a heating chamber 21a to ensure the sealing performance of the heating chamber 21a.

[0131] Furthermore, due to the effect of heat convection, the water vapor generated in the heating chamber 21a during the heating process will naturally rise, and in the embodiment of the present application, the exhaust pipe 24 is arranged on the tank top cover 212; that is, the tank top cover 212 is provided with a first through hole 2121, the exhaust pipe 24 is connected to the tank top cover 212, and another part of the exhaust pipe 24 extends into the heating chamber 21a through the first through hole 2121, so that the exhaust pipe 24 is communicated with the heating chamber 21a, facilitating the discharge of the water vapor generated in the heating chamber 21a during the heating process from the exhaust pipe 24.

[0132] Moreover, arranging the exhaust pipe 24 on the tank top cover 212 can prevent the liquid in the heating chamber 21a from flowing back; that is, if the exhaust pipe 24 is arranged at the bottom of the hot tank, when the external pressure (the water pressure for water replenishment) is greater than the pressure in the heating chamber 21a, water may flow back into the heating chamber 21a through the exhaust pipe 24, causing pollution and damage to the heating chamber 21a.

[0133] Please continue to refer to Figure 15 , in some embodiments, to ensure the normal operation of the hot tank assembly 20 and the safe heating of the liquid in the heating chamber 21a, the hot tank assembly 20 further includes a detection assembly 23, and the detection assembly 23 includes a water level detection element 232, a water quality detection element, and a temperature control element 237.

[0134] Specifically, the water level detection element 232 is connected to the tank body 21 and is in communication with the heating chamber 21a, so that the water level detection element 232 can detect the water level in the heating chamber 21a. And the type of the water level detection element 232 in the embodiments of the present application is not specifically limited. Exemplarily, the water level detection element 232 can be one of a float type water level sensor, an electrode type water level sensor, and a capacitance type water level sensor. Among them, the float type water level sensor detects the change of the water level by the up and down floating of the float. When the water level rises, the float also rises; when the water level drops, the float drops. The floating of the float will trigger a switch inside the float type water level sensor, thereby outputting a corresponding electrical signal to the control board 80 to facilitate detecting the water level in the heating chamber 21a. The electrode type water level sensor detects the water level by setting electrodes in the heating chamber 21a and utilizing the conductivity of water. When the water level rises and contacts the electrode, the circuit will be turned on, thereby outputting an electrical signal to the control board 80 to facilitate detecting the water level in the heating chamber 21a. The capacitance type water level sensor detects the water level by measuring the capacitance value formed between the capacitance type water level sensor and the water level. When the water level rises, the capacitance value will change, thereby outputting a corresponding electrical signal to the control board 80 to facilitate detecting the water level in the heating chamber 21a.

[0135] Please continue to refer to Figure 14 , further, in some embodiments, the water level detection element 232 includes a high water level probe 233 and a low water level probe 234. It can be understood that the high water level probe 233 is used to detect the position of the highest water level in the heating chamber 21a, and the low water level probe 234 is used to detect the position of the lowest water level in the heating chamber 21a; that is, when the liquid in the heating chamber 21a rises to the highest water level, the water inlet pipe 25 stops replenishing water to the heating chamber 21a to prevent the liquid in the heating chamber 21a from overflowing; when the liquid in the heating chamber 21a drops to the lowest water level, the water inlet pipe 25 replenishes water to the heating chamber 21a to prevent the heating chamber 21a from dry burning.

[0136] It should be noted that the positions of the high water level probe 233 and the low water level probe 234 provided on the tank body 21 in the embodiments of the present application are not specifically limited.

[0137] Please continue to refer to Figure 15, in another embodiment, the water level detection element 232 may include two high water level probes 233 and one low water level probe 234. Among them, the two high water level probes 233 may be arranged on the tank top cover 212, and the positions of the high water levels detected by the two high water level probes 233 are inconsistent; that is, there are a first high water level position and a second high water level position in the heating cavity 21a, and in the height direction of the tank body 21, the position of the first high water level is higher than that of the second high water level. At this time, one high water level probe 233 is used to detect the position of the first high water level, and the other high water level probe 233 is used to detect the position of the second high water level. When the other high water level probe 233 fails, the detection can still be carried out through one high water level probe 233 to improve the accuracy of the high water level probe 233 detection. Furthermore, the low water level probe 234 may be arranged on the tank top cover 212 or on the tank bottom cover 213 to detect the position of the lowest water level in the heating cavity 21a.

[0138] The water quality detection element is connected to the tank body 21 and communicates with the heating cavity 21a; that is, the water quality detection element is used to detect the quality of the liquid in the heating cavity 21a to ensure that safe and hygienic liquid is provided to the user. The type of the water quality detection element in the embodiments of the present application is not specifically limited. Exemplarily, the water quality detection element may be an electrochemical sensor, a biosensor, etc.

[0139] The temperature control element 237 is connected to the tank body 21 and communicates with the heating cavity 21a; that is, a part of the temperature control element 237 extends into the heating cavity 21a to facilitate the temperature control element 237 to detect the temperature of the liquid in the heating cavity 21a. Among them, the temperature control element 237 may be arranged on the tank top cover 212 or on the tank body 211, and the embodiments of the present application do not make specific limitations on this.

[0140] Please continue to refer to Figure 15 , further, in some embodiments, the temperature control element 237 includes a temperature control fixing plate 2371 and a temperature sensor 2372. Specifically, the temperature control fixing plate 2371 is connected to the tank body 21; that is, when the temperature control element 237 is installed on the tank body 211, the temperature control fixing plate 2371 can be fixed on the tank body 211, the tank top cover 212 or the tank bottom cover 213 by welding, screwing, clamping, bonding, etc. A second through hole 2373 communicating with the heating cavity 21a is provided on the temperature control fixing plate 2371, so that it is convenient for the temperature sensor 2372 to extend into the heating cavity 21a through the second through hole 2373, so that the temperature sensor 2372 can detect the temperature of the liquid in the heating cavity 21a. When the temperature of the liquid is too high, the control board 80 can control the heating element 22 to stop heating to protect the tank body 21.
