Description

Technical Field

[0001] This application relates to the field of water treatment equipment technology, specifically to a water treatment device. Background Technology

[0002] With the advancement of technology, people have developed diverse needs for domestic water. Water treatment equipment can treat the input water, such as adjusting its temperature and quality to meet user requirements, before outputting the treated water to users, greatly facilitating their lives. To control the water quality, flow rate, and temperature, water treatment equipment typically includes temperature-regulating components such as pumps, heaters, and coolers in its water system. Therefore, water treatment equipment usually has circuit boards and power cords for connecting to an external power source to provide power to these temperature-regulating components. Since these temperature-regulating components are all installed in the water system, the plugs on the circuit boards and power cords for connecting to external power sources are also located near the water system.

[0003] However, since the water system also needs to have a water passage for water to pass through, there is an inevitable risk of water leakage. Since the power cord is located near the water system, water leaking from the water passage can easily flow along the power cord to the plug and / or the vicinity of the circuit board, resulting in a certain risk of electric leakage in the water treatment equipment. Utility Model Content

One end of the power cord is connected to the circuit board, and the other end is located outside the receiving space and is used for inputting current.

[0006] In one specific embodiment, the isolation housing is provided with a first wire-passing hole connecting the first installation space and the second installation space, and the box is provided with a second wire-passing hole for connecting the first installation space and the outside. The power cable passes through the first wire-passing hole and the second wire-passing hole, and the end of the power cable near the second wire-passing hole is used to connect to a power source.

[0007] In one specific embodiment, the water system includes a hot tank assembly, which includes a tank body and an insulation sleeve. The tank body is fitted inside the insulation sleeve, and the outer surface of the insulation sleeve is provided with a wire passage groove.

[0009] In one specific embodiment, the base is provided with a first lifting mounting position, which is set corresponding to the second wire hole position, and the power cord is fixed to the first lifting mounting position; in the vertical direction, the height of the first lifting mounting position is higher than the bottom surface of the first mounting space.

[0010] In one specific embodiment, the base is further provided with a wire bevel, one end of which is connected to the wiring limiting structure, and the other end of which is connected to the first lifting mounting position, with the power cord abutting against the wire bevel.

[0011] In one specific embodiment, the base is further provided with a second lifting mounting position, which is provided corresponding to the first wire passage position, and the power cord is limited to the second lifting mounting position; in the vertical direction, the height of the second lifting mounting position and the first wire passage position is higher than the bottom surface of the first mounting space.

[0012] In one specific embodiment, the isolation housing is provided with a socket groove, the water system includes a heat exchanger assembly, the temperature regulating component includes a heater, the heater and the heat exchanger assembly are disposed in the socket groove, and the first wire passage is isolated from the socket groove.

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] With the advancement of technology, people have developed diverse needs for domestic water. Water treatment equipment can treat the input water, such as adjusting its temperature and quality to meet user requirements, before outputting the treated water to users, greatly facilitating their lives. To control the water quality, flow rate, and temperature, water treatment equipment typically includes temperature-regulating components such as pumps, heaters, and coolers in its water system. Therefore, water treatment equipment usually has circuit boards and power cords for connecting to an external power source to provide power to these temperature-regulating components. Since these temperature-regulating components are all installed in the water system, the plugs on the circuit boards and power cords for connecting to external power sources are also located near the water system.

[0025] However, since the water system also needs to have a water passage for water to pass through, there is an inevitable risk of water leakage. Since the power cord is located near the water system, water leaking from the water passage can easily flow along the power cord to the plug and / or the vicinity of the circuit board, resulting in a certain risk of electric leakage in the water treatment equipment.

[0026] In order to improve or solve the above technical problems, the inventors of this application, after long-term research, have proposed at least the following embodiments.

[0027] See Figures 1-4 , Figure 1 This is a schematic diagram of the assembly structure of an embodiment of the water treatment equipment of this application. Figure 2 yes Figure 1 A schematic diagram of the cross-sectional structure shown in section AA. Figure 3 yes Figure 1 A schematic diagram of the cross-sectional structure shown in section BB. Figure 4 This is a schematic diagram of the assembly structure of another embodiment of the water treatment equipment of this application. A specific embodiment of this application provides a water treatment equipment 1, including a main body 2, a circuit board 52, and a power cord 53.

[0028] The main body 2 of the device includes a water system 4, a temperature regulating component 51, and a housing assembly 3. The temperature regulating component 51 is connected to the water system 4. The housing assembly 3 includes a box 31 and an isolation shell 32. The box 31 has a receiving space 311. The isolation shell 32 is disposed within the receiving space 311 and divides the receiving space 311 into a first installation space 311a and a second installation space 311b. The water system 4 and the temperature regulating component 51 are disposed in the first installation space 311a. A circuit board 52 is disposed in the second installation space 311b and is electrically connected to the temperature regulating component 51. One end of a power cord 53 is connected to the circuit board 52, and the other end is located outside the receiving space 311 and is used for inputting current.

[0029] Water treatment equipment 1 refers to equipment that treats input water to meet user needs, typically used in residential, commercial, or industrial settings. Its water treatment methods may include at least one of filtration, heating, cooling, and softening. Specifically, water treatment equipment 1 can be a water purifier, water heater, water softener, chiller, etc.

[0030] The main body 2 refers to the core part of the water treatment equipment 1, including major modules such as the water circuit system 4, temperature control component 51, and shell assembly 3. The water input into the water treatment equipment 1 flows and is treated in the main body 2. For example, in an instant hot water dispenser, the main body 2 may include structures such as a thick film heater 511, a water pump, a valve body, and a water circuit board.

[0031] The circuit board 52 can be a PCB (Printed Circuit Board). The circuit board 52 serves as the support for various electronic components in the water treatment equipment 1 and also as the carrier for electrical connections between these components. The circuit board 52 connects various electronic components together through copper foil traces, forming a specific circuit functional module that functions as a control, drive, or signal processing unit in the water treatment equipment 1. These electronic components may include chips, resistors, capacitors, interfaces, etc. For example, in an instant hot water dispenser, the circuit board 52 can receive the user's water dispensing button command, then control the water pump, control the power of the heater 511, and can also be used to display water temperature or equipment status. The power cord 53 is a wire connecting the circuit board 52 to an external power source (such as a household socket) for transmitting electrical energy. The power cord 53 consists of an internal metal wire and an external insulating sheath. The power cord 53 can be connected to the power input interface on the circuit board 52 by soldering, plugging in terminals, etc., thereby introducing external electrical energy into the circuit board 52 and supplying power to the various electronic components in the water treatment equipment 1.

[0032] The water system 4 is the system for controlling the flow of water in the equipment, and may include structures such as inlets, outlets, pipes, valves, and pumps. The temperature control component 51 is used to change the water temperature and may be part of the water system 4. The isolation housing 32 is an independent, well-sealed housing installed inside the housing 31's accommodating space 311. Its function is to divide the large space into two smaller spaces: a first installation space 311a and a second installation space 311b. The first installation space 311a is used to install components such as the water system 4 and the temperature control component 51 through which water flows; water or water vapor is allowed to exist in this space. The second installation space 311b is used to install the circuit board 52 and the connection point between the power cord 53 and the circuit board 52; this space needs to prevent water from entering.

[0033] In the structure provided in this specific embodiment, the water system 4 and the circuit board 52 are physically separated in different installation spaces by the isolation housing 32, effectively reducing the risk of leakage of the water treatment equipment 1. Even if the water system 4 leaks, the water will be confined to the first installation space 311a by the isolation housing 32, and will not flow directly into the second installation space 311b or come into contact with the circuit board 52 in the second installation space 311b. This avoids short circuits or leakage caused by water flowing along the power line 53 to the circuit board 52 or the plug, thus improving the safety and reliability of the water treatment equipment 1.

[0034] like Figure 2 , 3 As shown in a specific embodiment of this application, the isolation housing 32 is provided with a first wire passage 321 connecting the first installation space 311a and the second installation space 311b, and the box body 31 is provided with a second wire passage 312 for connecting the first installation space 311a and the outside. The power cable 53 passes through the first wire passage 321 and the second wire passage 312, and the end of the power cable 53 near the second wire passage 312 is used to connect to the power source.

[0035] The first wire-passing hole 321 is a hole formed in the isolation housing 32 to allow the power cord 53 and other wire harnesses to enter the first installation space 311a from the second installation space 311b. For example, the first wire-passing hole 321 can be a suitably sized hole formed in the isolation housing 32 through which the power cord 53 passes. This hole is typically equipped with a rubber sealing ring or filled with sealant to ensure that the gap between the power cord 53 and the first wire-passing hole 321 is tightly filled when the power cord 53 passes through, preventing water from seeping into the second installation space 311b through the hole.

[0036] The second wiring hole 312 is a hole formed in the housing 31 to allow the power cord 53 to pass through the first mounting space 311a and exit the receiving space 311, thereby enabling connection to an external power outlet. For example, the second wiring hole 312 can be a suitably sized hole formed in the isolation housing 32 through which the power cord 53 passes. This hole is typically equipped with a rubber sealing ring or filled with sealant to ensure that the gap between the power cord 53 and the second wiring hole 312 is tightly filled when the power cord 53 passes through, preventing water from flowing between the first mounting space 311a and the outside environment. The outside environment refers to the environment outside the water treatment equipment 1, such as the room environment in a user's home where the water treatment equipment 1 is placed.

[0037] In the structure provided in this specific embodiment, the routing of the power cord 53 is fixed by setting two specific wire-passing holes, namely the first wire-passing hole 321 and the second wire-passing hole 312. Although the power cord 53 is partially located inside the first mounting space 311a, the two ends of the power cord 53 that connect to the power supply and the circuit board 52 are located outside the first mounting space 311a. Even if there is water leakage inside the first mounting space 311a, the water can only flow along the outer sheath of the power cord 53 and will not come into contact with the two ends of the power cord 53 located outside the first mounting space 311a.

[0038] See Figure 2 , 3 5, Figure 5 This is an exploded structural diagram of an embodiment of the water treatment equipment of this application. In a specific embodiment of this application, the water system 4 includes a hot tank assembly 41, which includes a tank body 411 and an insulation sleeve 412. The tank body 411 is fitted inside the insulation sleeve 412. The outer surface of the insulation sleeve 412 is provided with a wire passage groove 413, and the power cable 53 is accommodated in the wire passage groove 413. The first wire passage hole 321 and the second wire passage hole 312 are provided at opposite ends of the wire passage groove 413.

[0039] The cable passage 413 can be a groove, channel, or conduit designed on the insulation sleeve 412, specifically designed to guide and accommodate cables such as the power cord 53, allowing them to pass neatly and orderly through the first installation space 311a. For example, the cable passage 413 can be a strip-shaped groove engraved on the outer wall of the insulation sleeve 412. The power cord 53 is a conductor connecting the water treatment equipment 1 to an external power source (such as a household socket) for transmitting electrical energy. The power cord 53 consists of an inner metal conductor and an outer insulating sheath.

[0040] The heating tank assembly 41 can be a structure integrating heating and insulation functions. The tank body 411 is used to heat the heat exchange medium and / or water, and the insulation sleeve 412 is used to insulate the heat exchange medium and / or water inside the tank body 411. A temperature regulating component 51 for heating the heat exchange medium and / or water can be directly installed in the tank body 411, or the heat exchange medium and / or water inside the tank body 411 can be thermally connected to the temperature regulating component 51 outside the tank body 411. The insulation sleeve 412 is a component wrapped around the outside of the tank body 411, and its interior is filled with insulating materials such as foam and glass wool. The main function of the insulation sleeve 412 is to reduce heat loss from the tank body 411 and prevent the heat emitted by the tank body 411 from adversely affecting other components in the water treatment equipment 1 or the external environment.

[0041] In the structure provided in this specific embodiment, the through-path 413 provides a dedicated routing path for the power cable 53, guiding and protecting it. This prevents the power cable 53 from scattering randomly within the first installation space 311a and prevents interference or wear between the power cable 53 and moving parts or sharp edges within the water treatment equipment 1. This eliminates the risk of short circuits and leakage caused by damage to the insulation layer of the power cable 53, significantly improving electrical safety. The clear routing path formed by the through-path 413 allows production line workers to quickly and accurately place the power cable 53 during assembly, improving the assembly efficiency of the water treatment equipment 1 and ensuring product consistency. During subsequent maintenance, maintenance personnel can also clearly understand the routing of the power cable 53, improving maintenance and repair efficiency.

[0042] See Figures 2-5 In one specific embodiment of this application, the housing assembly 3 further includes a base 33 disposed within the first mounting space 311a. The base 33 supports the lower end of the insulation sleeve 412, and the base 33 is fixedly connected to the insulation sleeve 412 and / or the housing 31. The base 33 includes a wiring limiting structure 331, which is disposed on the side surface of the base 33 facing the wire passage groove 413. The wiring limiting structure 331 limits the power cord 53 between the base 33 and the inner wall of the wire passage groove 413.

[0043] The base 33 is installed at the bottom of the first installation space 311a, below and supporting the hot tank assembly 41. The base 33 serves as a support and installation platform for the water system 4. The wiring restraint structure 331 is a physical feature on the base 33 specifically designed to restrict and secure the position of the electrical wire. For example, the wiring restraint structure 331 can be a semi-circular or U-shaped hook structure with an opening, in which the power cord 53 can be positioned and secured. Alternatively, the wiring restraint structure 331 can consist of several raised ribs forming a channel slightly wider than the diameter of the electrical wire, which can then secure the power cord 53.

[0044] In the structure provided in this specific embodiment, the base 33 can support the heavy water system 4, thereby reducing the vibration and shaking of the water system 4, ensuring the stability of the water connection, and reducing the risk of loosening and leakage of the joint due to long-term vibration. The wiring limiting structure 331 can further limit the power cable 53 already placed in the cable tray 413. While the groove shape of the cable tray 413 initially accommodates and guides the power cable 53, the wiring limiting structure 331 of the base 33 locks the power cable 53 to prevent displacement, which can effectively reduce the probability of the power cable 53 becoming loose or displaced from the tray when the water treatment equipment 1 is transported, moved, or when the water system 4 vibrates during operation. At the same time, the wiring limiting structure 331 can also alleviate the wear of the insulation layer caused by long-term micro-friction of the cable, thereby improving the durability and safe life of the water treatment equipment 1.

[0045] See Figures 2-5 In one specific embodiment of this application, the base 33 is provided with a first lifting mounting position 332, which corresponds to the second wire hole position 312, and the power cord 53 is fixed to the first lifting mounting position 332. In the vertical direction, the height of the first lifting mounting position 332 is higher than the bottom surface of the first mounting space 311a.

[0046] The first raised mounting position 332 is a specific structural position on the base 33 designed to be higher than other parts of the base 33 or the mounting plane. Its purpose is to limit the power cable 53 from extending through the second cable hole 312 to the end connected to the external power source. For example, the first raised mounting position 332 can be at least one of the following structures: a boss, a column, a through hole, a slot, a cable tie, or a cable holder, capable of supporting and limiting the power cable 53. The vertical direction is the direction perpendicular to the horizontal plane, also commonly referred to as the height direction. The bottom surface of the first mounting space 311a can refer to the inner surface of the lowest point of the first mounting space 311a, which can be the bottom inner wall of the housing 31. The bottom surface of the first mounting space 311a is where water collects when water accumulates inside the equipment.

[0047] Height is the vertical distance of a point in the vertical direction relative to a reference plane. In this specific embodiment, the height of the first lifting installation position 332 can be the vertical distance between the first lifting installation position 332 and the installation plane of the water treatment equipment 1, and the height of the bottom surface of the first installation space 311a can be the vertical distance between the bottom surface of the first installation space 311a and the installation plane of the water treatment equipment 1.

[0048] In the structure provided in this specific embodiment, by setting the first lifting mounting position 332, the height of the end of the power cord 53 connected to the power source is increased, which can reduce the probability that the end of the power cord 53 connected to the power source will be immersed in water in the first mounting space 311a. This helps to keep the end of the power cord 53 connected to the power source dry, and can reduce the probability that water in the first mounting space 311a will flow along the power cord 53 to the end of the power cord 53 connected to the power source. This reduces the short circuit or leakage problems caused by water flowing along the power cord 53 to the power source or plug, and improves the safety and reliability of the water treatment equipment 1.

[0049] like Figure 2 As shown in a specific embodiment of this application, the base 33 is further provided with a wire inclined surface 333. One end of the wire inclined surface 333 is connected to the wiring limiting structure 331, and the other end of the wire inclined surface 333 is connected to the first lifting mounting position 332. The power cord 53 abuts against the wire inclined surface 333.

[0050] Among them, the wire inclined surface 333 is an inclined plane or curved surface specially designed on the base 33. The wire inclined surface 333 serves as a bridging structure between the wiring limiting structure 331 and the first lifting mounting position 332, and can connect the two areas with different heights, the wiring limiting structure 331 and the first lifting mounting position 332.

[0051] In the structure provided in this specific embodiment, a wire ramp 333 is provided as a transition structure between the wiring limiting structure 331 and the first lifting mounting position 332. The wire ramp 333 forms a gentle slope, which allows the power line 53 to smoothly turn upward from the horizontal wiring limiting structure 331 to the first lifting mounting position 332. This greatly improves the mechanical stress state of the power line 53. At the same time, the wire ramp 333 ensures that the power line 53 is also constrained and positioned in the transition section, which can reduce the suspension, looseness, and shaking of the power line 53, and maintain the integrity and aesthetics of the internal wiring.

[0052] In addition, the inclined surface 333 of the conductor can also guide the installation of the power cord 53 and achieve efficient assembly. The operator only needs to first insert the power cord 53 into the wiring limit structure 331, then guide the power cord 53 upward naturally along the inclined surface, and finally fix it on the first lifting installation position 332. This makes the wiring operation intuitive, fast and less prone to errors, and ensures the consistency of the assembly quality of the water treatment equipment 1.

[0053] See Figures 2-5 In one specific embodiment of this application, the base 33 is further provided with a second lifting mounting position 334, which corresponds to the first wire-passing hole 321, and the power cord 53 is confined to the second lifting mounting position 334. In the vertical direction, the height of the second lifting mounting position 334 and the first wire-passing hole 321 is higher than the bottom surface of the first mounting space 311a.

[0054] The second lifting mounting position 334 is another raised structural position set on the base 33, used to fix one end of the power cord 53 connecting to the circuit board 52. Its function and shape are similar to the first lifting mounting position 332, but its position corresponds to the first wire hole position 321.

[0055] In the structure provided in this specific embodiment, the second lifting mounting position 334 keeps the end of the power cord 53 near the first wire passage position 321 at a height higher than the bottom of the first mounting space 311a. This reduces the probability that the end of the power cord 53 near the first wire passage position 321 will come into contact with water in the first mounting space 311a. This helps to keep the end of the power cord 53 connected to the circuit board 52 dry, which reduces the probability that water in the first mounting space 311a will flow to the circuit board 52 along the power cord 53. This reduces problems such as signal abnormalities, short circuits, or leakage caused by water flowing to the circuit board 52 along the power cord 53, thereby improving the safety and reliability of the water treatment equipment 1.

[0056] like Figure 5 As shown in a specific embodiment of this application, the isolation housing 32 is provided with a socket groove 322, the water system 4 includes a heat exchanger assembly 42, the temperature regulating component 51 includes a heater 511, the heater 511 and the heat exchanger assembly 42 are disposed in the socket groove 322, and the first wire hole 321 is isolated from the socket groove 322.

[0057] The heater 511 heats the water. In conjunction with the heat exchanger assembly 42, the heater 511 rapidly raises the flow rate of water to the required temperature. The function of the heat exchanger assembly 42 is to efficiently transfer the heat from the heat exchange medium in the tank 411 to the water. It allows heat exchange mediums and water at different temperatures to transfer heat through a material with good thermal conductivity while physically isolated, thereby heating the water using the heat exchange medium. For example, the heat exchanger assembly 42 may include a plate heat exchanger or a shell-and-tube heat exchanger. A plate heat exchanger is composed of multiple corrugated metal plates stacked together, with cold and hot fluids flowing and exchanging heat within adjacent plate channels. A shell-and-tube heat exchanger consists of one tube nested inside another, with the two fluids flowing in the inner tube and the interlayer between the inner and outer tubes, respectively.

[0058] The socket groove 322 is a recess, chamber, or mounting position directly molded into the body of the isolation housing 32, the shape and size of which match the components such as the heater 511 and the heat exchanger assembly 42. Exemplarily, the socket groove 322 may have guide ribs, screw posts, or snaps to ensure that the components such as the heater 511 and the heat exchanger assembly 42 can be assembled accurately and securely.

[0059] In the structure provided in this specific embodiment, a socket groove 322 is provided in the isolation housing 32, which is isolated from the first wire passage hole 321. The socket groove 322 accommodates the heater 511 and heat exchanger assembly 42 through which water flows, thus isolating the power cord 53 inserted in the first wire passage hole 321 from the socket groove 322. Even if the heater 511 and heat exchanger assembly 42 leak, the leaked water is isolated from the power cord 53 in the first wire passage hole 321 by the socket groove 322. This is beneficial for the management and protection of the water treatment equipment 1 and can reduce the probability of water or steam in the water treatment equipment 1 coming into contact with the power cord 53 and circuit board 52. At the same time, the socket groove 322 also has the effect of isolating and buffering the heat and vibration emitted by the heater 511 and heat exchanger assembly 42, which can alleviate the problem of accelerated aging of the insulation layer of the power cord 53 due to long-term exposure to heat and stress. The socket 322 can also protect other components such as the power cord 53 in the event of an explosion or other accident involving the heater 511 or heat exchanger assembly 42.

[0060] Furthermore, integrating the heater 511 and heat exchanger assembly 42 within the socket groove 322 facilitates centralized thermal insulation treatment, preventing excessive heat dissipation to other parts of the water treatment equipment 1, and also facilitates modular assembly, thereby improving the production efficiency of the water treatment equipment 1.

[0061] like Figure 6 As shown, Figure 6This is a schematic block diagram of the water circuit structure of an embodiment of the water treatment equipment of this application. In a specific embodiment of this application, the water circuit system 4 further includes a water circuit plate assembly 43, which is provided with a water supply circuit 431 and a heat exchange water inlet circuit 432. One end of the heat exchange water inlet circuit 432 is used to connect to a water source, and the other end is connected to the tank 411. One end of the water supply circuit 431 is used to connect to a water source, and the other end is used to connect to the heat exchanger assembly 42 and / or the heater 511.

[0062] The housing assembly 3 further includes multiple support frames 34, one end of each support frame 34 being connected to the water circuit board assembly 43 and the other end being connected to the base 33. The support frames 34, the base 33, and the isolation housing 32 surrounding the socket groove 322 are fixedly connected. The first wire passage 321 includes a wire conduit, which is disposed on the side of the isolation housing 32 opposite to the socket groove 322, and the power cable 53 passes through the wire conduit.

[0063] The water circuit board assembly 43 is a plate-shaped or block-shaped component integrating various water circuit elements, and can be made of engineering plastics such as POM (polyoxymethylene). The water circuit board assembly 43 achieves water flow switching, distribution, and connection through precision-machined water passage 431 and heat exchange inlet water passage 432. Valves, pump bodies, connectors, and other structures can be directly installed on the water circuit board assembly 43. Water passage 431 is the flow channel in the water circuit board assembly 43 used to transport treated water for final supply to the user. Heat exchange inlet water passage 432 is the flow channel in the water circuit board assembly 43 specifically used to transport the heat exchange medium to be heated to the tank 411. Exemplarily, the heat exchange inlet water passage 432 and water passage 431 can be connected to the same water source.

[0064] The support frame 34 is a mechanical part specifically designed for supporting, connecting, and reinforcing structures. For example, the support frame 34 can be a separate component, and its function is to provide additional mechanical connection and support between the water pipe assembly 43 and the base 33.

[0065] In the structure provided in this specific embodiment, the water circuit board assembly 43 integrates dispersed pipes, joints, valves, water flow sensors, and other potentially existing components into one unit, reducing the number of connections between water pipes and joints in traditional assembly and fundamentally reducing the risk of leakage. Furthermore, as a prefabricated module, the water circuit board assembly 43 requires only a few interface connections during assembly, improving assembly efficiency while avoiding fluctuations in assembly quality. Simultaneously, the water circuit board assembly 43 optimizes the structural layout of the water system 4, making the water system 4 more integrated and holistic, which is beneficial for the miniaturization of the water treatment equipment 1.

[0066] By connecting the water circuit board assembly 43 and the base 33 with a support frame 34 and fixing the support frame 34 to the isolation shell 32, a robust beam-column structure is established between the water circuit board assembly 43 and the base 33. This enhances the overall mechanical strength of the water treatment equipment 1, enabling it to better resist vibrations and impacts during transportation, handling, or use, and preventing structural deformation. Furthermore, the water circuit board assembly 43 has numerous inlet and outlet interfaces, the sealing of which is crucial. By firmly fixing the water circuit board assembly 43 with the support frame 34, the risk of loose joints and leaks due to shaking or deformation of the water circuit board assembly 43 is significantly reduced, improving the long-term reliability of the water treatment equipment 1.

[0067] Alternatively, the support frame 34 can be used as a vibration damping structure. For example, the support frame 34 itself can be designed as a flexible structure, or vibration damping pads can be used at its connection points to absorb and isolate the vibration generated by the water pump, prevent the vibration from being transmitted to the entire water treatment equipment 1 and generate noise, and also protect other precision components inside the water treatment equipment 1.

[0068] See Figure 6 In one specific embodiment of this application, the heat exchanger assembly 42 is provided with a hot water path 421 and a circulating water path 422 that are isolated from each other. The circulating water path 422 is connected to the tank 411, and the hot water path 421 is connected to the water usage path 431. The hot water path 421 and the circulating water path 422 are thermally connected. The heat exchanger assembly 42 also includes an insulation layer 423, which wraps around the outer periphery of the heat exchanger assembly 42 and is disposed within the socket groove 322.

[0069] Specifically, the heater 511 can be connected downstream of the hot water circuit 421. The heater 511 can further heat the water circuit that has been heated by the heat exchanger assembly 42. The heater 511 and the heat exchanger assembly 42 work together to quickly raise the flow rate of water to the required temperature.

[0070] Hot water path 421 is the channel through which the water supplied to the user in the heat exchanger assembly 42 flows. Cold water flows in from one end of hot water path 421, absorbs heat from circulating water path 422, and becomes hot water, which flows out from the other end of hot water path 421. Circulating water path 422 is filled with heat exchange medium. After flowing out of tank 411, the heat exchange medium flows through circulating water path 422, transferring heat to the cold water in hot water path 421. After cooling itself, it flows back to tank 411 for reheating, and so on. The insulation layer 423 is a material wrapped around the outside of the heat exchanger assembly 42 to reduce heat loss. The insulation layer 423 can be a porous material with low thermal conductivity, such as rubber and plastic insulation cotton, polyurethane foam, or glass wool. The water in circulating water path 422 and hot water path 421 can flow in opposite directions.

[0071] In the structure provided in this specific embodiment, heat exchange occurs through mutually isolated hot water path 421 and circulating water path 422. The heat exchange medium in the circulating water path 422 is heated within the tank 411 and then transfers heat to the drinking water flowing through the hot water path 421 at the heat exchanger assembly 42. The heat exchange medium in the circulating water path 422 can be preheated and stored in the tank 411, enabling instantaneous heat exchange when hot water is needed, providing an immediate heating effect. The heat exchanger assembly 42 is fixed to at least one of the three robust structural components: base 33, support frame 34, and water path plate assembly 43. This ensures that the potentially heavy and bulky heat exchanger assembly 42 is securely and reliably housed within the water treatment equipment 1, preventing loosening due to water flow impact or vibration, thus guaranteeing the airtightness of the water treatment equipment 1. Tank 411 The insulation layer 423 wraps around the entire heat exchanger assembly 42, ensuring that the heat exchange process takes place in a highly insulated environment. This reduces the heat lost to the air inside the water treatment equipment 1, further improving energy efficiency and preventing other components inside the water treatment equipment 1 from aging due to excessively high ambient temperatures. This ensures the service life and long-term stability of the water treatment equipment 1.

[0072] like Figure 6 As shown, the water system 4 may further include a water outlet path 54, a wastewater discharge path 55, and an exhaust path 56. The water outlet path 54 is connected downstream of the heater 511 and can output heated hot water. The water outlet path 54 can also be connected downstream of the heat exchange inlet path 432, allowing water that does not flow into the tank 411 to be output directly as ambient temperature water. The wastewater discharge path 55 can be located downstream of the tank 411 and the water outlet path 54, thereby discharging excess water. The exhaust path 56 connects to the tank 411 and can discharge gas inside the tank 411.
