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 discharging the treated water to users, greatly facilitating their lives. Common water treatment equipment typically uses integrated water circuit boards, where the water channels connect to the cavities within the tank. To support the water circuit board and tank, a metal frame is usually installed to reduce the pressure on the tank. However, the heavy weight of the metal frame makes the overall weight of the water treatment equipment too high, hindering transportation. Furthermore, the installation relationship between the metal frame, water circuit board, and tank is complex, resulting in low production and assembly efficiency. Removing the metal frame and directly using the tank to support the water circuit board would lead to excessive pressure on the tank, potentially causing damage. Utility Model Content

[0003] In view of this, this application provides a water treatment device that can simplify the structure of the water treatment device while ensuring stable support for the water circuit board and the tank.

[0004] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide a water treatment device, including a hot tank assembly and a water circuit board assembly. The hot tank assembly includes a tank body and a reinforcing structure disposed on the tank body, and the tank body is provided with a medium cavity. The water circuit board assembly is mounted on the top of the tank body and is provided with a water inlet, one end of which is connected to a water inlet pipe and the other end is connected to the medium cavity.

[0005] In one specific embodiment, the water treatment equipment further includes a support rod and a base supported below the hot tank assembly, the upper end of the support rod being connected to the water circuit board assembly, and the lower end of the support rod being connected to the base.

[0006] In one specific embodiment, the water treatment equipment includes a heat exchange component connected to the water circuit board and the lower end of the support rod.

[0007] In one specific embodiment, the water treatment equipment further includes a housing with an open receiving space, the heat exchange component being disposed within the receiving space, and the housing connecting the water circuit plate, the support rod, and the base to the periphery of the open receiving space.

[0008] In one specific embodiment, the water treatment equipment further includes an outer casing, within which an installation space is provided. The hot tank assembly, water circuit board assembly, base, support rod, and cover are disposed within the installation space. The side of the cover away from the receiving space is provided with one of a socket and a rod, and the side of the outer casing facing the installation space is provided with the other of a socket and a rod. The socket is connected and fixed to the rod.

[0009] In one specific embodiment, the heat exchange assembly includes a water exchange circuit board, and there are multiple support rods. The water exchange circuit board connects two adjacent support rods, and the base supports the water exchange circuit board from below. The heat exchange assembly includes a plate heat exchanger, the upper end of which is connected to the water circuit board assembly, and the lower end of which is connected to the water exchange circuit board. And / or, the water treatment equipment further includes a thick film heater, the upper end of which is connected to the water circuit board assembly, and the lower end of which is connected to the water exchange circuit board.

[0010] In one specific embodiment, the water treatment equipment further includes a panel, which is connected to the water circuit board, the support rod, and the base.

[0011] In one specific embodiment, the water circuit board assembly includes a water circuit board body and a water inlet pipe. The water inlet portion is disposed in the water circuit board body and the other portion is disposed in the water inlet pipe. One end of the water inlet pipe is connected to the water circuit board body and the other end extends into the medium cavity. The water inlet pipe abuts against the bottom of the tank and between the water circuit board body.

[0012] In one specific embodiment, the reinforcing structure includes reinforcing ribs disposed on the side wall of the tank, the reinforcing ribs extending vertically and protruding into the medium cavity.

[0013] In one specific embodiment, the hot tank assembly further includes an insulation layer that wraps around the outer periphery of the tank body and abuts against the top of the water circuit board assembly and the tank body.

[0014] The beneficial effects of this application include: eliminating the separate metal support frame and integrating the support function into the tank body itself through a reinforced structure, thereby enhancing the rigidity and pressure-bearing capacity of the tank top. This allows the tank to withstand the weight of the water circuit board assembly and other possible stresses, ensuring the overall structural strength and reliability of the water treatment equipment even after eliminating the metal support frame. Furthermore, the overall weight of the water treatment equipment is significantly reduced, thus lowering transportation costs and complexity. In traditional designs, the metal support frame, water circuit board assembly, and tank body are three independent parts with complex installation relationships. Simplifying the structure by having the water circuit board assembly directly mounted on the reinforced tank body significantly reduces the number of parts in the water treatment equipment and simplifies the assembly relationship between the water circuit board assembly and the tank body, significantly improving production and assembly efficiency and potentially reducing material management and manufacturing costs.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0023] 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 discharging the treated water to users, greatly facilitating their lives. Common water treatment equipment typically uses integrated water circuit boards, where the water channels connect to the cavities within the tank. To support the water circuit board and tank, a metal frame is usually installed to reduce the pressure on the tank. However, the heavy weight of the metal frame makes the overall weight of the water treatment equipment too high, hindering transportation. Furthermore, the installation relationship between the metal frame, water circuit board, and tank is complex, resulting in low production and assembly efficiency. Removing the metal frame and directly using the tank to support the water circuit board would lead to excessive pressure on the tank, potentially causing damage.

[0024] 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.

[0025] participate Figures 1-6 , Figure 1 This is a schematic diagram of the assembly structure of the first embodiment of the water treatment equipment of this application. Figure 2 This is an exploded structural diagram of the second embodiment of the water treatment equipment of this application. Figure 3 This is an exploded structural diagram of the third embodiment of the water treatment equipment of this application. Figure 4 This is a schematic diagram of the assembly structure of the fourth embodiment of the water treatment equipment of this application. Figure 5 yes Figure 1 A schematic diagram of the cross-sectional structure shown in section AA. Figure 6 yes Figure 1 The cross-sectional view shown in Figure BB is a schematic diagram. This application provides a water treatment device 1, including a heat tank assembly 2 and a water circuit board assembly 4.

[0026] The hot tank assembly 2 includes a tank body 21 and a reinforcing structure 3 disposed on the tank body 21. The tank body 21 has a medium cavity 22. The water channel plate assembly 4 is mounted on the top of the tank body 21. The water channel plate assembly 4 has a water inlet 43, one end of which is connected to a water inlet pipe and the other end of which is connected to the medium cavity 22.

[0027] The water treatment equipment 1 refers to a device capable of heating, cooling, or performing other physical treatments on water. For example, the water treatment equipment 1 can be an instant water dispenser, a water purifier with heating or cooling functions, a commercial electric water heater, etc. The heating tank assembly 2 is the core heating, heat storage, and pressure-bearing component of the water treatment equipment 1, and also serves as a container. The medium cavity 22 inside the tank 21 can store the heated water or other media. The water circuit board assembly 4 is an integrated water circuit system and control center, capable of integrating multiple water pipe joints, valves, water flow channels, and other functions onto a single plate-shaped component, greatly simplifying the connection of pipes in the water treatment equipment 1. For example, the water treatment equipment 1 can be an engineering plastic plate with multiple flow channels formed internally by carving or injection molding, and the plate is equipped with an inlet, an outlet, and an interface for connecting to the heating tank.

[0028] The reinforcing structure 3 is a feature specifically designed to enhance the structural strength of the tank 21, ensuring that the tank 21 can withstand pressure from both inside and outside without the use of an external metal frame. For example, the reinforcing structure 3 can be multiple vertical grooves formed by stamping on the side wall of the metal tank 21. The water inlet path 43 refers to the entire flow path of water or other media from the water inlet pipe to the medium cavity 22. The water inlet path 43 may be composed of various physical components. The water inlet pipe can be an external domestic water pipe, the outlet pipe of a pre-filter, etc., or it can be the filter outlet pipe or heat exchanger outlet pipe inside the water treatment equipment 1.

[0029] In the specific embodiment of this application, the independent metal support is eliminated, and the supporting function is integrated into the tank 21 itself through the reinforcing structure 3. This enhances the rigidity and pressure-bearing capacity of the top of the tank 21, enabling it to withstand the weight of the water circuit board assembly 4 and other possible stresses. Thus, even without the metal support, the overall structural strength and reliability of the water treatment equipment 1 are maintained, and the overall weight of the water treatment equipment 1 is significantly reduced, thereby lowering transportation costs and difficulties. Furthermore, in traditional designs, the metal support, water circuit board assembly 4, and tank 21 are three independent parts with complex installation relationships. By simplifying the structure so that the water circuit board assembly 4 is directly installed on the tank 21 with the reinforcing structure 3, the number of parts in the water treatment equipment 1 is significantly reduced, and the assembly relationship between the water circuit board assembly 4 and the tank 21 is simplified, significantly improving production and assembly efficiency and potentially reducing material management and manufacturing costs.

[0030] like Figures 2-4 As shown in a specific embodiment of this application, the water treatment equipment 1 further includes a support rod 51 and a base 52 supported below the hot tank assembly 2. The upper end of the support rod 51 is connected to the water circuit board assembly 4, and the lower end of the support rod 51 is connected to the base 52.

[0031] Among them, the support rod 51 is lighter than the original metal bracket and can assist the tank 21 and strengthen the structure 3. For example, the assembly of the support rod 51 and the base 52 can be such that the upper ends of the four support rods 51 are symmetrically locked to the four corners of the water channel plate assembly 4, and the lower ends of the support rods 51 are symmetrically locked to the base 52 made of plastic or metal.

[0032] In the specific embodiment of this application, a robust support structure is established between the water circuit board assembly 4 and the base 52 using a support rod 51. This structure helps the reinforcing structure 3 of the tank 21 to distribute the pressure and various possible stresses of the water circuit board assembly 4. The weight and various stresses of the water circuit board assembly 4 can be directly transferred to the base 52 through the support rod 51, instead of being entirely borne by the tank 21, thereby reducing the mechanical load on the tank 21 and improving the stability of the water treatment equipment 1. Furthermore, the support rod 51 tightly connects the upper water circuit board assembly 4, the middle hot tank assembly 2, and the lower base 52 of the water treatment equipment 1 into a rigid integral structure, greatly improving the overall structural strength and resistance to shaking and bumps of the water treatment equipment 1.

[0033] See Figure 4 In one specific embodiment of this application, the water treatment equipment 1 includes a heat exchange component 53, which is connected to the water circuit board and the lower end of the support rod 51.

[0034] Among them, the heat exchange assembly 53 is a collection of components used for heat exchange, specifically a heat exchanger, such as a shell-and-tube heat exchanger.

[0035] In the specific embodiment of this application, the heat exchange component 53 is used to connect the lower end of the water circuit board and the support rod 51. The heat exchange component 53 can be regarded as part of the support rod 51 structure, which not only solves the installation problem of the heat exchange component 53, but also strengthens the support structure, shares the weight of the water circuit board assembly 4 and the vibration and stress generated during the operation of the water treatment equipment 1, and further improves the overall structural strength and anti-shaking and anti-bumping ability of the water treatment equipment 1.

[0036] See Figure 3 In one specific embodiment of this application, the water treatment equipment 1 further includes a cover 55, the cover 55 having an open receiving space 551, the heat exchange component 53 being disposed within the receiving space 551, and the cover 55 connecting the water circuit plate, the support rod 51 and the base 52 to the periphery of the open receiving space 551.

[0037] Among them, the cover 55 is an intermediate shell used to wrap and protect the internal core components such as the heat exchange component 53. It is not only a protective cover, but also a structural component, which serves to connect the water circuit board and the base 52 and reinforce the support rod 51.

[0038] In the specific embodiment of this application, the casing 55, as an external structure, can integrate the water circuit board, support rod 51, heat exchange component 53, and base 52 into a unified module, firmly binding the water circuit board, support rod 51, heat exchange component 53, and base 52 together, minimizing the small displacements or deformations that may occur between the components during transportation or use, bearing and dispersing impacts and vibrations from all directions, reducing the burden on the tank 21 and the reinforcing structure 3, and making the structure of the water treatment equipment 1 more stable.

[0039] See Figure 5 In one specific embodiment of this application, the water treatment equipment 1 further includes a housing 56, within which an installation space 561 is provided. The hot tank assembly 2, the water circuit board assembly 4, the base 52, the support rod 51, and the cover 55 are disposed within the installation space 561. The side of the cover 55 facing away from the receiving space 551 has one of a socket 562 and a rod 552, while the side of the housing 56 facing the installation space 561 has the other of a socket 562 and a rod 552. The socket 562 is inserted and fixedly connected to the rod 552.

[0040] Among them, the outer shell 56 is an outer shell used to wrap and protect the internal core components such as heat exchange component 53, hot tank component 2, and water circuit board component 4. While forming the appearance of water treatment equipment 1, it also serves to constrain the internal components and reinforce the cover 55.

[0041] In the specific embodiment of this application, the cooperation between the insertion rod 552 and the insertion hole 562 is an efficient guiding and positioning structure. When assembling the outer shell and the cover 55, the outer shell 56 can provide support for the cover 55 through the cooperation between the insertion rod 552 and the insertion hole 562, further distributing the weight and stress borne by the tank 21 and the reinforcing structure 3, making the water treatment equipment 1 more integrated, reducing the amplitude of shaking, displacement or vibration between various structures in the water treatment equipment 1, and ensuring the reliability of the water treatment equipment 1 for long-term use.

[0042] See Figure 4In one specific embodiment of this application, the heat exchange assembly 53 includes a heat exchange water circuit plate 532, and there are multiple support rods 51. The heat exchange water circuit plate 532 connects two adjacent support rods 51, and the base 52 supports the heat exchange water circuit plate 532. The heat exchange assembly 53 includes a plate heat exchanger 531, the upper end of which is connected to the water circuit plate assembly 4, and the lower end of which is connected to the heat exchange water circuit plate 532. And / or, the water treatment equipment 1 further includes a thick film heater 54, the upper end of which is connected to the water circuit plate assembly 4, and the lower end of which is connected to the heat exchange water circuit plate 532.

[0043] The plate heat exchanger 531 is composed of a stack of corrugated metal sheets pressed together. Cold water and hot water flow separately through adjacent sheets, exchanging heat through the metal sheets. The water exchange circuit board 532 is a board with a function similar to the circuit board assembly 4 but specifically designed to serve the plate heat exchanger 531. It has internal flow channels for connecting the plate heat exchanger 531 and the circuit board assembly 4. The thick film heater 54 is a highly efficient instantaneous heating element that rapidly heats the flowing water by printing a layer of conductive heating material onto a circuit board-shaped substrate.

[0044] In the specific embodiment of this application, the heat exchanger plate 532 simultaneously bears three functions: connecting the plate heat exchanger 531 and the water circuit plate assembly 4, serving as a structural reinforcing beam between the support rods 51, and supporting the weight of the plate heat exchanger 531 and / or the thick film heater 54. The heat exchanger plate 532 tightly connects adjacent support rods 51, preventing radial displacement of the lower part of the support rods 51 and greatly enhancing the torsional and lateral force resistance of the entire support frame. Furthermore, the base 52 rests beneath the heat exchanger plate 532, meaning that the core stress point of the entire frame falls on this most robust three-dimensional structure, rather than entirely on the tank 21, thus unloading the heat tank assembly 2 and constructing an extremely stable three-dimensional load-bearing frame inside the water treatment equipment 1, improving the structural stability of the water treatment equipment 1. Both the plate heat exchanger 531 and the thick film heater 54 are connected to the water circuit plate assembly 4 at one end and the heat exchanger plate 532 at the other end; as rigid components, they also reinforce the support rods 51.

[0045] See Figure 2 In one specific embodiment of this application, the water treatment device 1 further includes a panel 57, which is connected to the water circuit board, the support rod 51, and the base 52. The panel 57 is a cover plate at the front of the water treatment device 1, and typically integrates a user interface for interaction with external devices or the user.

[0046] In the specific embodiment of this application, a panel 57 with a certain rigidity is used to connect the water circuit board, support rod 51 and base 52, providing support for the tank 21 and reducing the burden on the tank 21 and the reinforcing structure 3. At the same time, the panel 57 can further assist the support rod 51, improve the load-bearing and vibration model of the water treatment equipment 1. When the water treatment equipment 1 vibrates during operation, the panel 57 can change the resonance frequency of the core load-bearing structure and effectively suppress the vibration, thereby reducing the noise generated in the water treatment equipment 1 and making the water treatment equipment 1 operate more quietly and stably.

[0047] See Figure 6 In a specific embodiment of this application, the water circuit board assembly 4 includes a water circuit board body 41 and a water inlet pipe 42. The water inlet 43 is partially disposed in the water circuit board body 41 and partially disposed in the water inlet pipe 42. One end of the water inlet pipe 42 is connected to the water circuit board body 41 and the other end extends into the medium cavity 22. The water inlet pipe 42 abuts against the bottom of the tank 21 and the water circuit board body 41.

[0048] The water inlet pipe 42 can be a pipe that extends downward from the main body 41 of the water circuit board and inserts into the bottom of the tank 21. The water inlet pipe 42 not only forms the water inlet path 43, but also has a structural support function.

[0049] In the specific embodiment of this application, a water inlet pipe 42 is added inside the tank 21 to form a columnar support structure. The water inlet pipe 42 can not only transport fluid but also support the water circuit board assembly 4. The water inlet pipe 42 can transfer a portion of the weight and installation stress of the water circuit board assembly 4 to the bottom of the tank 21, providing a support point for the water circuit board. This can further reduce the probability of the water circuit board deforming due to uneven stress and also reduce the pressure on the tank 21, thereby improving the structural stability of the water treatment equipment 1.

[0050] See Figure 2 , Figure 3 , Figure 5 In one specific embodiment of this application, the reinforcing structure 3 includes a reinforcing rib 31, which is disposed on the side wall of the tank body 21 and extends vertically and protrudes into the medium cavity 22.

[0051] In the specific embodiment of this application, reinforcing ribs 31 are provided on the side wall of the flat tank 21. These reinforcing ribs 31 significantly increase the moment of inertia of the tank 21, improving its resistance to bending and deformation. Simultaneously, in the event of negative pressure inside the tank 21, the vertical reinforcing ribs 31 provide strong support to the side wall of the tank 21, much like creases on a piece of paper help it stand upright. This greatly improves the tank 21's resistance to radial compression and reduces the probability of it being crushed by atmospheric pressure. The support rod 51 and the tank 21 jointly bear the weight and bending moment of components such as the water channel plate assembly 4. The reinforcing ribs 31 help the tank 21 share some of the torque transmitted to it, ensuring sufficient local strength and overall stability to withstand the load, thus improving the structural stability of the tank 21.

[0052] See Figure 5 , Figure 6 In one specific embodiment of this application, the hot tank assembly 2 further includes an insulation layer 58, which wraps around the outer periphery of the tank body 21 and abuts against the top of the water circuit board assembly 4 and the top of the tank body 21.

[0053] The insulation layer 58 is a material layer wrapped around the tank body 21 for heat insulation. For example, the insulation layer 58 can be foamed rubber or polyethylene foam wrapped around the outer periphery of the tank body 21.

[0054] In the specific embodiment of this application, the insulation layer 58 wrapped around the outer periphery of the tank 21 effectively blocks heat exchange between the inside of the tank 21 and the external cold air. This directly reduces the heating frequency and energy consumption of the water treatment equipment 1, and improves the energy utilization rate of the water treatment equipment 1. At the same time, the insulation layer 58 is compressed between the water circuit board assembly 4 and the top of the tank 21, acting as a pre-tightening and buffer pad, which can evenly distribute the weight of the water circuit board assembly 4. The insulation layer 58 wrapped around the periphery of the tank 21 can also provide a certain degree of support for the tank 21, reducing the probability of deformation of the tank 21 due to uneven local stress, and improving the structural stability of the water treatment equipment 1.
