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. Water treatment equipment typically includes a tank with a media cavity for storing water and other media. An integrated water circuit board is usually located above the tank. To input or output media into or from the bottom of the media cavity, a tank extending into the cavity is required. Because the pipe and water circuit board are not integrally formed, the connection may loosen, causing the pipe to slide down into the bottom of the media cavity. This can result in the end of the pipe, away from the water circuit board, hitting the bottom of the cavity and becoming blocked, isolating the pipe's interior from the cavity and preventing further input or output of media.

[0007] In one specific embodiment, the abutting structure includes an abutting surface of the pipe body disposed around the opening, and the pipe body around the opening is further provided with a water outlet slope, the bottom end of which is connected to the abutting surface; when the abutting surface abuts the bottom surface of the medium cavity, the water outlet slope keeps the opening connected to the medium cavity.

[0008] In one specific embodiment, the water treatment equipment further includes a limiting structure, which is used to limit one end of the pipe body having the opening. The limiting structure is disposed on the bottom surface of the medium cavity and / or the pipe body around the opening.

[0009] In one specific embodiment, the limiting structure includes a limiting protrusion, which is disposed on the bottom surface of the medium cavity and protrudes into the medium cavity. The limiting protrusion is used to contact the inner wall and / or outer wall of the tube to limit the tube.

[0011] In one specific embodiment, the limiting structure includes a limiting groove, which is disposed on the bottom surface of the medium cavity and recessed in a direction away from the medium cavity. The limiting groove is used to accommodate and limit the end of the tube body that has an opening.

[0012] In one specific embodiment, there are multiple water passage holes, which are evenly distributed around the opening of the pipe body.

[0013] In one specific embodiment, the water treatment equipment includes a heat exchanger, the heat exchanger having a hot water exchange path, the water system including a heat exchange inlet path and a heat exchange return path, the main body of the water circuit plate having a return water interface connected to the pipe body; the medium cavity, the heat exchange inlet path, the hot water exchange path, the heat exchange return path, the return water interface, and the pipe body are sequentially connected to form a medium water circuit, the medium in the medium cavity can flow back into the medium cavity through the opening after flowing through the medium water circuit; and / or, the water system includes a wastewater discharge path, the main body of the water circuit plate having a wastewater discharge interface connected to the pipe body, one end of the wastewater discharge path communicating with the medium cavity through the wastewater discharge interface and the opening, and the other end being used to discharge the medium in the medium cavity.

[0014] The beneficial effects of this application include: by setting a stop structure, even if the pipe body slides down, the stop structure will abut between the opening of the pipe body and the bottom of the medium cavity, so that at least part of the opening can still communicate with the medium cavity; by setting a water passage hole, even if the opening is completely blocked when the pipe body slides down and the opening abuts the bottom of the medium cavity, the water passage hole can still connect the medium cavity and the water system, thereby keeping the path of medium flow in the pipe body always unobstructed, which is equivalent to setting up a backup channel for medium flow, greatly improving the fault tolerance of the water treatment equipment, reducing the strength requirements of the connection between the pipe body and the main body of the water circuit board, providing a certain process tolerance for the processing of the water circuit board components, thereby reducing the production cost and assembly difficulty of the water treatment equipment. Even if the connection between the pipe body and the main body of the water circuit board becomes slightly loose after long-term use, the function of the water treatment equipment will not be affected.

[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 outputting the treated water to users, greatly facilitating their lives. Water treatment equipment typically includes a tank with a media cavity for storing water and other media. An integrated water circuit board is usually located above the tank. To input or output media into or from the bottom of the media cavity, a tank extending into the cavity is required. Because the pipe and water circuit board are not integrally formed, the connection may loosen, causing the pipe to slide down into the bottom of the media cavity. This can result in the end of the pipe, away from the water circuit board, hitting the bottom of the cavity and becoming blocked, isolating the pipe's interior from the cavity and preventing further input or output of media.

[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] See Figures 1-7 , Figure 1 This is a schematic diagram of the assembly structure of an embodiment of the water treatment equipment of this application. Figure 2 This is an exploded structural diagram of another embodiment of the water treatment equipment of this application. Figure 3 yes Figure 1 A schematic diagram of the cross-sectional structure shown in section AA. Figure 4 yes Figure 3 A magnified structural diagram of region C in the middle. Figure 5 yes Figure 1 A schematic diagram of the cross-sectional structure shown in section BB. Figure 6 yes Figure 5 A magnified structural diagram of region D in the middle. Figure 7 This is a schematic block diagram of the water circuit structure of an embodiment of the water treatment equipment of this application. A specific embodiment of this application provides a water treatment equipment 1, including a tank assembly 2 and a water circuit board assembly 3.

[0026] The tank assembly 2 is provided with a medium cavity 21. The water circuit board assembly 3 includes a water circuit board body 31 and a pipe body 33. A water circuit system 32 is provided in the water circuit board body 31. One end of the pipe body 33 is connected to the water circuit board body 31, and the other end extends into the medium cavity 21. An opening 331 is provided at the end of the pipe body 33 away from the water circuit board. The opening 331 connects the water circuit system 32 and the medium cavity 21. The water treatment equipment 1 also includes a supporting structure 4. The supporting structure 4 is disposed on the bottom surface of the medium cavity 21 and / or the pipe body 33 around the opening 331. When the pipe body 33 slides down, the supporting structure 4 abuts against the bottom surface of the pipe body 33 and the medium cavity 21. The opening 331 connects to the medium cavity 21.

[0027] Optionally, the pipe body 33 around the opening 331 is provided with a water passage hole 332. When the opening 331 is blocked, the water passage hole 332 connects the medium cavity 21 and the water system 32.

[0028] Among them, water treatment equipment 1 refers to a device that stores a medium internally and needs to circulate or discharge wastewater, which can perform physical or chemical treatment on water, such as an instant water heater, water dispenser, or pipeline water heater. Tank assembly 2 is the main container of the equipment, and its internal cavity is the medium cavity 21, which is used to contain and treat water or other media.

[0029] The water circuit board assembly 3 is typically a plate-shaped component with complex internal etched or machined flow channels. It is responsible for connecting different functional modules of the water treatment equipment 1, such as the water source, tank, heat exchanger 6, and drain outlet, through internal flow channels to achieve the distribution and guidance of water or other media. The water circuit system 32 is a network of pipes integrated inside the water circuit board body 31. The pipe body 33 is the bridge for fluid transport between the tank and the upper water circuit board. One end of the pipe body 33 is connected to the water circuit board, and the other end extends into the bottom of the medium cavity 21. The opening 331 is the main channel for the medium to enter and exit the tank assembly 2.

[0030] The top-stopping structure 4 is a physical structure whose core function is to prevent the opening 331 from being completely sealed off from the bottom surface of the medium cavity 21 when the pipe body 33 accidentally slides down, thus ensuring that the opening 331 is always at least partially open. The water passage hole 332 is an additional hole opened on the side wall of the pipe body 33 near the end of the opening 331, used as a backup channel for the medium to enter and exit the pipe body 33.

[0031] In the specific embodiment of this application, by providing the abutting structure 4, even if the pipe body 33 slides down, the abutting structure 4 will abut between the opening 331 of the pipe body 33 and the bottom of the medium cavity 21, so that at least part of the opening 331 can still communicate with the medium cavity 21. By providing the water passage hole 332, when the pipe body 33 slides down and the opening 331 abuts the bottom of the medium cavity 21, even if the opening 331 is completely blocked, the water passage hole 332 can still connect the medium cavity 21 and the water system 32, thereby keeping the path of medium flow in the pipe body 33 always unobstructed, which is equivalent to setting up a backup channel for medium flow.

[0032] The structure of the specific embodiment of this application greatly improves the fault tolerance of the water treatment equipment 1, reduces the strength requirements at the connection between the pipe body 33 and the water circuit board body 31, and provides a certain process tolerance for the processing of the water circuit board assembly 3. This can reduce the production cost and assembly difficulty of the water treatment equipment 1. Even if the connection between the pipe body 33 and the water circuit board body 31 becomes slightly loose after long-term use, the function of the water treatment equipment 1 will not be affected.

[0033] In one specific embodiment, the abutting structure 4 is disposed on the bottom surface of the medium cavity 21. The abutting structure 4 is used to abut a portion of the tube body 33 around the opening 331, and another portion of the tube body 33 around the opening 331 and the bottom surface of the medium cavity 21 have a pore for water passage.

[0034] In the specific embodiment of this application, the abutting structure 4 abuts only the pipe body 33 around the opening 331, while the other part of the opening 331 is necessarily used to form a pore for water passage. Mechanically, it is forced to maintain a state of incomplete blockage. No matter how the pipe body 33 rotates or what the bottom of the medium cavity 21 is like, this pore guaranteed by the cooperation between the pipe body 33 and the abutting structure 4 will always exist, which greatly improves the reliability of the abutting structure 4.

[0035] In one specific embodiment, the abutment structure 4 includes a strip-shaped protrusion 41, which is arranged radially along the opening 331 on the bottom surface of the medium cavity 21, and the strip-shaped protrusion 41 protrudes into the medium cavity 21.

[0036] In the specific embodiment of this application, the radially arranged strip-shaped ribs 41 create two fan-shaped openings on both sides of the ribs when the pipe body 33 slides down and abuts against them. This creates a larger total cross-sectional area for the water flow while occupying a smaller contact area, providing a wide inlet and a gradually converging flow path for the medium, effectively reducing the resistance to the medium flow. Simultaneously, the strip-shaped ribs 41 structure itself has high compressive strength and rigidity, is easy to process, and is not easily deformed or worn under long-term stress, ensuring low processing costs and long-term reliability.

[0037] In one specific embodiment, the abutting structure 4 includes an abutting surface 42 disposed around the opening 331 on the pipe body 33. The pipe body 33 around the opening 331 also has a water outlet slope 43, the bottom end of which is connected to the abutting surface 42. When the abutting surface 42 abuts against the bottom surface of the medium cavity 21, the water outlet slope 43 keeps the opening 331 connected to the medium cavity 21.

[0038] In the specific embodiment of this application, by designing the end of the pipe body 33 with the opening 331 as a composite structure of abutment surface 42 and outlet slope 43, even if the end of the pipe body 33 with the opening 331 slips, only the abutment surface 42 will always contact the bottom of the medium cavity 21. At the same time, a wedge-shaped flow channel with a gradually increasing cross-sectional area is naturally formed between the outlet slope 43 and the bottom of the medium cavity 21, which greatly improves the reliability of the water circuit board assembly 3. During the water discharge process, the medium rushes out from the wedge-shaped flow channel, spreads along the slope, and can smoothly diffuse to the bottom of the entire medium cavity 21, resulting in smooth flow. During the water inlet process, the medium at the bottom of the medium cavity 21 can be easily guided into the opening 331 along the outlet slope 43, thereby reducing suction eddies and flow resistance. Even if the pipe body 33 slips, the performance of the flowing medium will not be greatly affected.

[0039] Meanwhile, the outlet slope 43 is very easy to process. It only requires beveling the end of the pipe body 33 with the opening 331. There is no need to consider the alignment problem between the top structure 4 and the pipe body 33. The bottom of the medium cavity 21 can be kept as the simplest plane, which simplifies the mold design, manufacturing and assembly process of the tank and reduces the production cost of the water treatment equipment 1.

[0040] In one specific embodiment, the water treatment device 1 further includes a limiting structure 5, which is used to limit one end of the pipe body 33 where the opening 331 is provided. The limiting structure 5 is disposed on the bottom surface of the medium cavity 21 and / or the pipe body 33 around the opening 331.

[0041] The limiting structure 5 is used to actively prevent the tube 33 from rotating or shifting, and to precisely fix the end with the opening 331 in an ideal position. For example, the limiting structure 5 can be a protruding positioning pin, which fits tightly against the inner or outer wall of the tube 33 to prevent it from swaying or rotating. The limiting structure 5 can also be a recessed groove, into which the end of the tube 33 with the opening 331 can be inserted. The groove's contour matches the contour of the tube 33, thus limiting the tube 33 in all directions.

[0042] In the specific embodiment of this application, by setting the limiting structure 5, a rigid limit is achieved on the end of the pipe body 33 with the opening 331. After the pipe body 33 slides down, even if there is water flow impact, pressure fluctuation or vibration of the water treatment equipment 1, the end of the pipe body 33 with the opening 331 is difficult to slide relative to the bottom surface of the medium cavity 21. It can simultaneously restrict the radial movement and circumferential rotation of the pipe body 33. It can cooperate with the top structure 4 to ensure that the top structure can always be effective to keep the pipe body 33 unobstructed, and enhance the overall rigidity of the pipe body 33 and the tank assembly 2, and improve the stability and anti-interference ability of the water circuit board assembly 3.

[0043] In one specific embodiment, the limiting structure 5 includes a limiting protrusion 51, which is disposed on the bottom surface of the medium cavity 21 and protrudes into the medium cavity 21. The limiting protrusion 51 is used to contact the inner wall and / or outer wall of the tube body 33 to limit the tube body 33.

[0044] In the specific embodiment of this application, the limiting protrusion 51 protruding from the bottom surface of the medium cavity 21 directly contacts the inner wall and / or outer wall of the pipe body 33, achieving precise and firm radial and circumferential positioning of the end of the pipe body 33 with the opening 331. Together with the abutment structure 4, they rigidly lock the sliding pipe body 33 in a position that can stably connect the water circuit system 32 and the medium cavity 21, thereby improving the stability and anti-interference ability of the water circuit board assembly 3.

[0045] In one specific embodiment, the abutting structure 4 is disposed on the bottom surface of the medium cavity 21, and the limiting structure 5 is disposed on the abutting structure 4 and / or on the periphery of the abutting structure 4.

[0046] In the specific implementation of this application, the limiting structure 5 and the abutting structure 4 are integrated or closely connected to form a functionally integrated limiting structure 5. This limiting structure 5, as a whole, solves the problems of the pipe body 33 sliding down and the pipe body 33 end offset at the same time. As long as the end of the pipe body 33 with the opening 331 is correctly connected with this limiting structure 5, it can complete the positioning in all directions at once. This can save the internal space of the tank assembly 2, and greatly simplify the design logic of the water treatment equipment 1, and improve the accuracy and coordination of the water treatment equipment 1.

[0047] In one specific embodiment, the limiting structure 5 includes a limiting groove 52, which is disposed on the bottom surface of the medium cavity 21 and recessed in a direction away from the medium cavity 21. The limiting groove 52 is used to accommodate and limit one end of the tube body 33 that has an opening 331.

[0048] In the specific embodiment of this application, the recessed limiting groove 52 is used to accommodate and constrain the end of the tube 33 with the opening 331. The limiting groove 52 forms a near-all-around wrap around the end of the tube 33, which greatly reduces the probability of the tube 33 shaking or shifting in any horizontal direction. This realizes the concept shift from support positioning to nested installation. While providing excellent stability and precise positioning, it also guides the installation of the tube 33, protects the end of the tube 33 and the top structure 4 from collisions and scratches, and simplifies the internal structure of the tank assembly 2.

[0049] Meanwhile, when the opening 331 is used as an outlet, the water flow is guided by the limiting groove 52 after flowing out of the opening 331, and spreads evenly to the surrounding area along the annular structure of the limiting groove 52; when the opening 331 is used as an inlet, the water at the bottom of the medium cavity 21 will be preferentially drawn in from this annular structure, which is more efficient and orderly than letting the water flow spread freely on the bottom plane of the open medium cavity 21.

[0050] In one specific embodiment, there are multiple water passage holes 332, and the multiple water passage holes 332 are evenly distributed on the pipe body 33 around the opening 331.

[0051] If there is only one water passage 332, when used as an outlet, it will form a concentrated jet that may impact the tank assembly 2, the pipe 33, and the water circuit board body 31, causing noise, vibration, or unnecessary disturbance. In the structure of the specific embodiment of this application, a highly efficient, stable, and failure-resistant redundant flow channel system is constructed through the uniform arrangement of multiple water passages 332. Even if some water passages 332 are blocked by foreign objects, the other water passages 332 can still maintain the connection between the medium cavity 21 and the water circuit system 32, greatly improving the stability of the water circuit board assembly 3.

[0052] Meanwhile, the evenly arranged multiple water passages 332 not only ensure the stable flow of the medium when the opening 331 is blocked, but also optimize the flow performance of the medium and reduce the flow resistance of the medium. This allows the outflowing medium to flow evenly and symmetrically to the surroundings, and the inflowing medium to be smoothly and evenly drawn in from the surroundings. This greatly improves the flow field inside the tank assembly 2, reduces turbulence, vibration and energy loss, and makes the water treatment equipment 1 operate more smoothly, quietly and efficiently.

[0053] In one specific embodiment, the water treatment equipment 1 includes a heat exchanger 6, which has a hot water exchange passage 61. The water system 32 includes a heat exchange inlet passage 321 and a heat exchange return passage 322. The main body of the water circuit board 31 has a return water interface 311, which is connected to the pipe body 33. The medium cavity 21, the heat exchange inlet passage 321, the hot water exchange passage 61, the heat exchange return passage 322, the return water interface 311, and the pipe body 33 are sequentially connected to form a medium water circuit. The medium in the medium cavity 21 can flow back into the medium cavity 21 through the opening 331 after flowing through the medium water circuit. And / or, the water system 32 includes a wastewater discharge channel 323, the main body 31 of the water system plate is provided with a wastewater discharge interface 312, the wastewater discharge interface 312 is connected to the pipe body 33, one end of the wastewater discharge channel 323 is connected to the medium cavity 21 through the wastewater discharge interface 312 and the opening 331, and the other end is used to discharge the medium in the medium cavity 21.

[0054] The medium water path is a complete circulation loop used to draw water, brine regeneration solution, oil, and other media from the tank assembly 2, input them into the heat exchanger 6's heat exchanger water path 61 via the heat exchanger inlet water path 321 for treatment, and then return them to the tank via the heat exchanger return water path 322. This allows the media to store heat within the tank assembly 2 and release heat in the heat exchanger water path 61, achieving a heat exchange cycle for the media. The wastewater path 323 is a one-way discharge path used to completely discharge the media that needs to be discarded from the medium container 21 into the water treatment equipment 1.

[0055] In the specific embodiment of this application, by integrating the design of the pipe body 33, the top structure 4, and the water passage 332 into the two key parts of the medium water passage and / or the wastewater discharge passage 323, the stability and reliability of the two major functions of medium circulation and wastewater discharge in the water treatment equipment 1 are ensured, the maintenance requirements of the two major functions of medium circulation and wastewater discharge are reduced, the automation level of the water treatment equipment 1 is improved, thereby ensuring the long-term stable operation of the water treatment equipment 1 and the stable realization of its basic functions.
