Description

Technical Field

[0001] This invention relates to the field of water treatment equipment technology, and more particularly to water treatment devices. Background Technology

[0002] A water softener is a water treatment device that removes calcium and magnesium ions from water through ion exchange to reduce water hardness. Water softeners typically use resin as the filter element. The softening efficiency of the connecting valve is related to the volume of the resin tank and the size of the resin filter element. To improve softening capacity, water softeners often use multiple resin tanks connected in series to form a longer softening flow channel. To achieve this, the softening valve of the water softener has multiple water passages connecting to each resin tank. Water flows between the resin tanks and the softening valve, forming a series softening flow channel. Connecting multiple resin tanks through a single softening valve can lead to inefficient spatial arrangement, and the complex and large internal water passage structure of the softening valve occupies a significant amount of internal space in the water softener, making the entire unit bulky and unsuitable for confined spaces. Summary of the Invention

[0003] The purpose of this invention is to provide a water treatment device that can solve the problems of existing water softeners, which use softening valves connected in series with multiple resin tanks, resulting in unreasonable space layout, complex softening valve structure, and large internal space occupation of the water softener, making the whole machine large in size and unsuitable for confined spaces.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A water treatment device is provided, including a water treatment component, a connecting valve, and at least one bypass pipe. The water treatment component includes at least two treatment tanks, each treatment tank having a protrusion on its top. Each treatment tank has an inlet and an outlet that connect to an internal accommodating cavity. The connecting valve is used for communication between an external water supply end, an external water user end, and the water treatment component.

[0007] In one embodiment, a portion of the top of the processing tank extends axially outward to form the protrusion, or a portion of the top of the processing tank is recessed axially inward so that the top of the remaining portion forms the protrusion.

[0009] The protrusion is eccentrically positioned, and its projection along the axial direction of the treatment tank covers the water inlet channel and the water outlet channel. The water inlet and / or the water outlet are located on the outer side wall of the protrusion.

[0010] In one embodiment, both the inlet and the outlet are located on the outer wall of the protrusion. In two adjacent treatment tanks, along the direction of the raw water flow, the outlet of the upstream treatment tank faces the same direction as the inlet of the downstream treatment tank, or the outlet of the upstream treatment tank faces an angle with the inlet of the downstream treatment tank.

[0011] In one embodiment, the protrusion has a fan-shaped cross-section, and the protrusion has two radially outer sidewalls arranged at an angle, and an arc-shaped outer sidewall connecting the two radially outer sidewalls. The inlet and the outlet are both located on the radially outer sidewalls.

[0012] In one embodiment, two adjacent protrusions are located on the same side of the axis connecting the two processing tanks, or two adjacent protrusions are located on opposite sides of the axis connecting the two tanks.

[0013] In one embodiment, the connecting valve includes a first extension pipe having a first connection port and a second extension pipe having a second connection port, the first extension pipe and the second extension pipe being used to connect the water treatment assembly, the connecting valve being disposed above the treatment tank such that the first extension pipe and the second extension pipe extend into the receiving space, and the bypass pipe being located beside the protrusion so as to be located within the receiving space.

[0014] In one embodiment, the water treatment assembly includes two treatment tanks connected in series and a bypass pipe. Along the direction of raw water flow, the two treatment tanks are sequentially configured as a first treatment tank and a second treatment tank. The first treatment tank has a connecting inlet for connecting to the first connecting port, and the second treatment tank has a connecting outlet for connecting to the second connecting port. The connecting inlet and the connecting outlet face the accommodating space.

[0015] In one embodiment, both the first treatment tank and the second treatment tank have the protrusion, the connecting inlet is opened at the end of the first treatment tank or the corresponding protrusion, and the first extension pipe is a straight pipe or an L-shaped pipe to adapt to the orientation of the connecting inlet.

[0016] The connecting outlet is located at the end of the second treatment tank or the corresponding protrusion, and the second extension pipe is a straight pipe or an L-shaped pipe to adapt to the orientation of the connecting outlet.

[0017] In one embodiment, the connecting valve has an inlet, an outlet, and a drain outlet. The inlet is connected to an external water supply, the outlet is connected to an external water user, and the drain outlet is used to discharge wastewater. The inlet is connected to a first connecting port, and the second connecting port can selectively connect to either the outlet or the drain outlet to form a working mode or a forward flushing mode.

[0018] In one embodiment, the connecting valve has an inlet, an outlet, and a drain outlet.

The inlet can selectively connect to a second connecting port, and when the inlet is connected to the second connecting port, the first connecting port selectively connects to the drain outlet to form a backwashing mode.

[0019] In one embodiment, the connecting valve has an inlet, a drain outlet, and a brine inlet. Each treatment tank is equipped with a resin filter element.

[0022] The water treatment device provided by this invention includes a water treatment component, a connecting valve, and at least one bypass pipe. The water treatment component includes at least two treatment tanks. One end of each treatment tank has a protrusion, and the treatment tank has an inlet and an outlet connecting to an internal accommodating cavity. The connecting valve is used for communication between an external water supply end, an external water user end, and the water treatment component. A bypass pipe is provided between two adjacent treatment tanks. Along the direction of raw water flow, the two ends of the bypass pipe are respectively connected to the outlet of one treatment tank and the inlet of the other treatment tank, forming a series connection of at least two treatment tanks. Through the bypass pipe, water flows sequentially through multiple treatment tanks to form a series water path, without needing to flow through the connecting valve, which simplifies the internal water path structure of the connecting valve and reduces its spatial volume. Moreover, the cross-sectional dimension of the protrusion is smaller than the cross-sectional dimension of the treatment tank, and an accommodating space is formed on the side of the protrusion, within which at least part of the bypass pipe and / or at least part of the connecting valve is located.

[0031] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] like Figure 1 and Figure 2 As shown, this embodiment first provides a water treatment device, which includes a water treatment component 1, a connecting valve 2 and at least one bypass pipe 3. The water treatment component 1 includes at least two treatment tanks. The treatment tanks can be soft water tanks with soft water filter elements such as resin filter elements, or they can be clean water tanks with purification filter elements such as RO membrane reverse osmosis filter elements. This embodiment does not impose any specific limitations.

[0036] One end of the treatment tank has a protrusion 11. The treatment tank has an inlet 12 and an outlet 13 that connect to the internal accommodating cavity. A connecting valve 2 is used to connect the external water supply end, the external water use end, and the water treatment component 1. A bypass pipe 3 is provided between two adjacent treatment tanks. Along the direction of raw water flow, the two ends of the bypass pipe 3 are respectively connected to the outlet 13 of one treatment tank and the inlet 12 of another treatment tank to form a series connection of at least two treatment tanks. With the bypass pipe 3, the water flows through multiple treatment tanks in sequence to form a series water path, without needing to flow through the connecting valve 2, which simplifies the internal water path structure of the connecting valve 2 and reduces the spatial volume of the connecting valve 2. Moreover, the cross-sectional dimension of the protrusion 11 is smaller than the cross-sectional dimension of the treatment tank, and an accommodating space 14 is formed on the side of the protrusion 11. At least part of the bypass pipe 3 and / or at least part of the connecting valve 2 are located in the accommodating space 14. The water treatment device of this invention cleverly utilizes the smaller size of the protrusion 11 compared to the treatment tank to form a accommodating space 14, which accommodates part of the bypass pipe 3 and the connecting valve 2. This reduces the additional internal space volume occupied by the bypass pipe 3 and the connecting valve 2 in the water treatment device. The water treatment components 1, the connecting valve 2, and the bypass pipe 3 form a more reasonable spatial layout, making the internal structure of the water treatment device more compact and meeting the space requirements of confined spaces.

[0037] The protrusion 11 may be formed by a portion of the top of the processing tank extending outward along the axial direction of the processing tank, or by the top of the processing tank being recessed inward along the axial direction of the processing tank, so that the top of the remaining portion forms the protrusion 11. This embodiment does not impose specific limitations.

[0038] Along the direction of raw water flow, the treatment tank has an inlet channel and an outlet channel. Raw water enters the treatment tank through the inlet channel, is treated by the filter element, and then flows out through the outlet channel. The outlet channel is located at the center of the receiving cavity, while the inlet channel surrounds the periphery of the outlet channel. Inlet 12 connects to the inlet channel, and outlet 13 connects to the outlet channel. A protrusion 11 is eccentrically positioned, and its projection along the axial direction of the treatment tank covers both the inlet and outlet channels. Inlet 12 and / or outlet 13 are located on the outer wall of the protrusion 11. Compared to an axially eccentrically positioned protrusion 11, this design better guides the water flow in and out. Thus, when outlet 13 is located on the outer wall of protrusion 11, it directly connects to the central outlet channel, preventing interference between the outlet and inlet water flows. Furthermore, when the inlet 12 and outlet 13 located on the outer wall of the protrusion 11 are connected to the bypass pipe 3 via a connector, both the connector and the bypass pipe 3 are located within the accommodating space 14 on the side of the protrusion 11, which does not increase the dimensions of the treatment tank in the height direction, thus facilitating the compactness and miniaturization of the water treatment device.

[0039] It should be noted that the water outlet channel is located in the center of the containment cavity. The center mentioned here does not refer to the exact center of the treatment tank, but rather to the central area extending axially within the containment cavity.

[0040] In one embodiment, for example, both the inlet 12 and the outlet 13 are located on the outer wall of the protrusion 11. In two adjacent treatment tanks, along the direction of raw water flow, the outlet 13 of the upstream treatment tank faces the same direction as the inlet 12 of the downstream treatment tank. Thus, the bypass pipe 3 is U-shaped to connect the inlet 12 and the outlet 13 with the same opening direction. Along the direction of raw water flow, the U-shaped bypass pipe 3 has an inlet port 31 and an outlet port 32. The inlet port 31 is used to connect to the outlet 13 of the upstream protrusion 11, and the outlet port 32 is used to connect to the inlet 12 of the downstream protrusion 11.

[0041] In other embodiments, the outlet 13 of the upstream treatment tank and the inlet 12 of the downstream treatment tank can also be oriented at an angle, and the orientation of the outlet 13 and the inlet 12 can be adapted by changing the extension direction of the bypass pipe 3. Figure 6 As shown in the figure, the outlet 13 of the upstream treatment tank and the inlet 12 of the downstream treatment tank are set at a 90° angle. At this time, the bypass pipe 3 is L-shaped.

[0042] Of course, in order to adapt to the orientation of the outlet 13 and the inlet 12, in other embodiments, the bypass pipe 3 may also be Z-shaped or a straight pipe, etc. This embodiment does not impose specific restrictions.

[0043] To connect the connecting valve 2 and the water treatment component 1 to form a circulating water circuit, the connecting valve 2 includes a first extension pipe 21 with a first connecting port 211 and a second extension pipe 22 with a second connecting port 221. Both the first extension pipe 21 and the second extension pipe 22 are used to connect to the water treatment component 1. The connecting valve 2 is positioned above the treatment tank so that the first extension pipe 21 and the second extension pipe 22 extend into the accommodating space 14, and the bypass pipe 3 is located beside the protrusion 11 within the accommodating space 14. This improves the accommodating capacity of the accommodating space 14, allowing it to simultaneously accommodate parts of the connecting valve 2 and the bypass pipe 3.

[0044] Figure 2 The diagram illustrates a water treatment device with two treatment tanks and one bypass pipe 3. When the number of treatment tanks in the water treatment device is greater than two, the number of bypass pipes 3 increases accordingly. For example, if the water treatment device has three treatment tanks, then correspondingly, two bypass pipes 3 are provided, meaning one bypass pipe 3 is provided between every two adjacent treatment tanks. In other embodiments, the number of treatment tanks and bypass pipes 3 in the water treatment device can be increased or decreased according to the purification capacity requirements; this embodiment does not impose any limitations.

[0045] The layout of the water treatment component 1, the connecting valve 2, and the bypass pipe 3 is described below with reference to specific embodiments.

[0046] Example 1

[0047] like Figures 3 to 5 As shown, in this embodiment, the water treatment assembly 1 includes two treatment tanks connected in series and a bypass pipe 3. Both treatment tanks are soft water tanks, and along the direction of raw water flow, the two treatment tanks connected in series sequentially form a first treatment tank 15 and a second treatment tank 16. The first treatment tank 15 has a connecting inlet 151 for connecting to a first connecting port 211 of the connecting valve 2, and the second treatment tank 16 has a connecting outlet 161 for connecting to a second connecting port 221 of the connecting valve 2, to form a circulating water path. The connecting inlet 151 and the connecting outlet 161 face the accommodating space 14 to facilitate the arrangement of the connecting valve 2.

[0048] Both the first treatment tank 15 and the second treatment tank 16 have protrusions 11, which increase the volume of the accommodating cavity, allowing for a larger water storage capacity and improving the softening ability of the water treatment device. A connecting inlet 151 is located at the end of the first treatment tank 15 or at the corresponding protrusion 11. The first extension pipe 21 is a straight pipe or an L-shaped pipe to adapt to the orientation of the connecting inlet 151. A connecting outlet 161 is located at the end of the second treatment tank 16 or at the corresponding protrusion 11. The second extension pipe 22 is a straight pipe or an L-shaped pipe to adapt to the orientation of the connecting outlet 161. That is, when the connecting inlet 151 is located at the end of the first treatment tank 15, the first extension pipe 21 is a straight pipe; when the connecting inlet 151 is located on the outer wall of the corresponding protrusion 11, the first extension pipe 21 is an L-shaped pipe to adapt to the orientation of the connecting inlet 151. Similarly, when the connecting outlet 161 is located at the end of the second treatment tank 16, the second extension pipe 22 is a straight pipe; when the connecting outlet 161 is located on the outer side wall of the corresponding protrusion 11, the second extension pipe 22 is an L-shaped pipe to adapt to the orientation of the connecting outlet 161.

[0049] like Figure 4 As shown, the protrusion 11 has a separator 111 to form a first channel 112 and a second channel 113 that are isolated from each other. The first channel 112 connects to the water inlet channel, and the second channel 113 connects to the water outlet channel. When both the water inlet 12 and the water outlet 13 are located on the outer wall of the protrusion 11, the flow direction of the raw water at the water inlet 12 and the water outlet 13 is horizontal. This is at an angle to the extension direction of the water inlet channel and the water outlet channel of the vertically installed treatment tank. Therefore, the first channel 112 can guide the flow direction of the water entering the water inlet channel from the water inlet 12, and the second channel 113 can guide the flow direction of the water entering the water outlet 13 from the water outlet channel, thereby improving the flow of water.

[0050] The protrusion 11 has a fan-shaped cross-section and two radially outer sidewalls 114 arranged at an included angle, and an arc-shaped outer sidewall 115 connecting the two radially outer sidewalls 114. The inlet 12 and the outlet 13 are both located on the radially outer sidewalls 114. The radially outer sidewalls 114 facilitate the arrangement of connectors, and the arc-shaped outer sidewalls 115 can maximize the volume of the accommodating cavity.

[0051] like Figure 5 As shown, two adjacent protrusions 11 are located on the same side of the line connecting the axes of the two processing tanks. Furthermore, the two fan-shaped arcuate outer walls 115 are arranged opposite each other to further optimize the spatial layout.

[0052] For example, such as Figure 2As shown, the connecting inlet 151 is located at the end of the first treatment tank 15, at the edge of the end, and is directly connected to the water inlet channel of the first treatment tank 15, with the water flow direction being the same, resulting in better water flow. The connecting outlet 161 is located on a radially outer side wall 114 of the protrusion 11 of the second treatment tank 16, and faces the receiving space 14. To accommodate the opening directions of the connecting inlet 151 and the connecting outlet 161, the first extension pipe 21 is a straight pipe, and the second extension pipe 22 is an L-shaped bend.

[0053] The outlet 13 is located on one radially outer side wall 114 of the protrusion 11 of the first treatment tank 15, and the inlet 12 is located on the other radially outer side wall 114 of the protrusion 11 of the second treatment tank 16, with the outlet 13 and inlet 12 facing the same direction. Thus, the first extension pipe 21 and the second extension pipe 22 are arranged in the partial accommodating space 14 between the two protrusions 11, and the bypass pipe 3 is arranged in the partial accommodating space 14 formed on the other side of the axis connecting the two protrusions 11, reducing the possibility of interference between the bypass pipe 3 and the first extension pipe 21 and the second extension pipe 22. Furthermore, the bypass pipe 3, arranged on the side, is easy to install, inspect, and replace, and will not affect the first treatment tank 15, the second treatment tank 16, or the connecting valve 2. Quick-connect fittings are used between the bypass pipe 3 and the outlet 13 and inlet 12, further improving the convenience of maintenance and replacement. The structure of the quick-connect fittings can be designed according to existing technology, which is not the focus of this application and will not be described in detail here.

[0054] To minimize the distance between the first treatment tank 15 and the second treatment tank 16, the first extension pipe 21 and the second extension pipe 22 are staggered along the axis connecting the first treatment tank 15 and the second treatment tank 16. In this embodiment, the staggered arrangement of the first extension pipe 21 and the second extension pipe 22 allows the first treatment tank 15 and the second treatment tank 16 to be closer together, which helps to reduce the size of the water treatment device along the axis connecting the first treatment tank 15 and the second treatment tank 16.

[0055] Example 2

[0056] In this embodiment, the water treatment component 1 has two series-connected treatment tanks and a bypass pipe 3, identical to those in Embodiment 1. Both treatment tanks are soft water tanks, and along the direction of raw water flow, the two series-connected treatment tanks sequentially form a first treatment tank 15 and a second treatment tank 16. The remaining identical structures will not be described in detail in this embodiment.

[0057] like Figure 6 As shown, in this embodiment, the first processing tank 15 and the second processing tank 16 have two protrusions 11 located on both sides of the axis connecting line and arranged opposite to each other.

[0058] When both protrusions 11 are fan-shaped, the central angles of the two fan shapes are aligned. The bypass pipe 3 is L-shaped to connect the inlet 12 and the outlet 13. The connecting inlet 151 is located on the protrusion 11 of the first treatment tank 15, and the connecting outlet 161 is located on the protrusion 11 of the second treatment tank 16. The first extension pipe 21 and the second extension pipe 22 are both L-shaped to accommodate the orientation of the connecting inlet 151 and the connecting outlet 161, respectively. This simplifies the manufacturing process of the water treatment device. The protrusion 11 of the first treatment tank 15 has two openings, and the protrusion 11 of the second treatment tank 16 also has two openings. They can be processed using the same injection mold, as long as the bypass pipe 3 and the connecting valve 2 use the same connector structure.

[0059] It should be noted that, in Figure 6 In one embodiment, the protrusion 11 of the second processing tank 16 is located in the second quadrant of one end face of the second processing tank 16, and the protrusion 11 of the first processing tank 15 is located in the fourth quadrant of the first processing tank 15. In other embodiments, the protrusion 11 of the second processing tank 16 may also be located in the third quadrant of one end face of the second processing tank 16, and the protrusion 11 of the first processing tank 15 may be located in the first quadrant of the first processing tank 15.

[0060] Example 3

[0061] This invention provides a water treatment device, which includes two series-connected treatment tanks and a bypass pipe 3, as shown in Embodiment 1 or Embodiment 2. This embodiment will not elaborate on identical structures.

[0062] In this embodiment, the connecting valve 2 also has an inlet 23, an outlet 24, and a drain 25. The inlet 23 is connected to an external water supply terminal, the outlet 24 is connected to an external water user terminal, and the drain 25 is used to discharge wastewater. The inlet 23 is connected to a first connecting port 211, and the second connecting port 221 can selectively connect to the outlet 24 or the drain 25 to form a working mode or a forward flushing mode. In the working mode, the inlet 23 is connected to the first connecting port 211, and the second connecting port 221 is connected to the outlet 24. The raw water supplied by the external water supply terminal flows through the connecting valve 2 into the water treatment component 1, and after being softened by the first treatment tank 15 and the second treatment tank 16 in sequence, the soft water is supplied to the external water user terminal through the outlet 24. In the forward flushing mode, the inlet 23 is connected to the first connecting port 211 and the second connecting port 221 is connected to the drain port 25. The raw water supplied by the external water supply flows through the connecting valve 2 into the water treatment component 1, and sequentially flushes the filter elements in the first treatment tank 15 and the second treatment tank 16. The resulting wastewater is discharged through the drain port 25.

[0063] To further improve the flushing effect, the inlet 23 can selectively connect to the second connecting port 221. When the inlet 23 is connected to the second connecting port 221, the first connecting port 211 selectively connects to the drain port 25 to form a backwashing mode. In the backwashing mode, the raw water supplied by the external water supply flows into the water treatment component 1 through the connecting valve 2. Since the second connecting port 221 is connected to the connecting outlet 161 of the second treatment tank 16, the flow direction of the raw water in the second treatment tank 16 and the first treatment tank 15 is opposite to the flow direction in the forward flushing mode, resulting in a more thorough flushing of the filter element. The raw water sequentially backwashes the filter elements in the second treatment tank 16 and the first treatment tank 15, and the resulting wastewater is discharged through the drain port 25.

[0064] The resin filter element inside the treatment tank will become saturated after prolonged use. The connecting valve 2 also has a brine inlet 26. The brine inlet 26 is used to inject brine into the connecting valve 2. The second connecting port 221 can selectively connect to both the inlet 23 and the brine inlet 26 simultaneously. When the second connecting port 221 connects to both the inlet 23 and the brine inlet 26, the first connecting port 211 selectively connects to the drain port 25 to form a regeneration mode. In regeneration mode, the raw water supplied from the external water supply end and the brine supplied from the brine inlet 26 are mixed and flow sequentially through the second treatment tank 16 and the first treatment tank 15 to regenerate the resin filter element. The mixed solution soaks the resin filter element, allowing sodium ions to reoccupy their exchange sites and restoring the resin filter element's softening function.

[0065] To provide brine for the regeneration mode, the water treatment unit also includes a brine tank (not shown in the figure). The brine tank has a brine chamber for containing brine. Initially, the brine tank contains solid salt, which occupies less space than the brine. The brine chamber is connected to a brine intake port 26, and the brine tank is connected to a connecting valve 2. The brine intake port 26 can selectively connect to the inlet port 23 to form a water replenishment mode. The water replenishment mode is set before the regeneration mode. In the water replenishment mode, raw water supplied from an external water supply flows through the connecting valve 2 into the brine tank to dissolve the solid salt and form brine, which is used in the subsequent regeneration mode.

[0066] The above-mentioned structure, achieved by the connecting valve 2, is as follows: the second connecting port 221 selectively connects to the outlet 24 or the sewage outlet 25; the inlet port 23 selectively connects to the second connecting port 221 or the first connecting port 211; the first connecting port 211 selectively connects to the sewage outlet 25 and the outlet 24; and the brine supply port 26 selectively connects to the second connecting port 221 and the inlet port 23. This structure can be set with reference to the prior art, but it is not the focus of this application and will not be described in detail here.

[0067] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
