Description
Technical Field
[0001] The utility model relates to the field of waterway plates, in particular to a waterway plate component and a water purifier comprising the same. Background Art
[0002] The waterway board is a common material for water purifiers on the market. By integrating the waterway, it replaces the pipes in the machine's internal waterway, making the structure more compact and beautiful, while also reducing the risk of water leakage. However, there are many bends in the waterway board, which can easily produce dead water areas, that is, water areas that do not flow much, because they are blocked by the subsequent fast-flowing water. These dead water areas will gradually produce colonies over time, causing phenomena such as excessive bacterial colonies in the outlet water. At present, there is no sterilization solution for the internal pipes of the waterway board on the market, and it is impossible to sterilize the entire pipe while avoiding the possibility of the sterilizer rupturing due to excessive water flow. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the defect of the prior art that a dead water zone is generated when an external sterilizer is used, and to provide a waterway plate assembly and a water purifier comprising the same.
[0004] The utility model solves the above technical problems through the following technical solutions:
[0005] The utility model provides a waterway plate assembly, which is characterized in that the waterway plate assembly comprises a light guide plate, a sterilizing device and a waterway plate, wherein the waterway plate has a water flow channel formed by a partition wall;
[0006] The light guide plate is arranged inside the waterway plate and laid on at least a portion of the partition wall;
[0007] The sterilization device is arranged outside the water channel plate and close to the light guide plate, so that the ultraviolet rays generated by the sterilization device are irradiated into the water flow channel through the light guide plate.
[0008] In this solution, by arranging a light guide plate in the waterway plate, the ultraviolet rays generated by the sterilization device can be irradiated through the light guide plate to the water flow channel in the waterway plate, and the entire water flow channel can be sterilized, thereby avoiding the formation of bacterial colonies in dead water areas. At the same time, the sterilization device is arranged on the outside of the waterway plate to avoid damage to the sterilization device caused by the impact of water flow, thereby improving the safety of the waterway plate.
[0009] Preferably, the plane where the light guide plate is located is parallel to the plane where the plate body of the waterway plate is located, and the plane where the light guide plate is located passes through the water flow channel.
[0010] In this solution, the light guide plate is arranged on the plane where the plate body of the waterway plate is located, which is convenient for installation inside the waterway plate. It can be arranged along the flow direction of the liquid in the waterway plate without affecting the water resistance in the water flow channel, thereby avoiding damage to the light guide plate caused by water flow during long-term use.
[0011] Preferably, the water flow channel includes an inlet waterway, a wastewater waterway and a clean water waterway, wherein the coverage of the partition wall of the light guide plate on the clean water waterway is greater than the coverage of the partition wall of the light guide plate on the inlet waterway or the wastewater waterway.
[0012] In the present embodiment, the water flow channel includes an inlet waterway, a wastewater waterway and a clean water waterway, wherein the coverage rate of the light guide plate on the partition wall on the clean water waterway is greater than the coverage rate of the light guide plate on the partition wall on the inlet waterway or the coverage rate of the light guide plate on the partition wall on the wastewater waterway. This is because the area of the waterway plate that mainly needs to be sterilized is the clean water pipeline. Reducing the coverage rate of the light guide plate on the partition wall on the inlet waterway and the wastewater waterway can save the light guide plate laying area, thereby simplifying the structure.
[0013] Preferably, the light guide plate completely covers the water purification channel, and the water channel plate also covers at least a portion of the water inlet channel.
[0014] In this solution, the light guide plate completely covers the purified water channel and at least part of the inlet water channel, thereby achieving sterilization of both the purified water channel and the inlet water channel, thereby improving the sterilization effect.
[0015] Preferably, at least one first through hole is provided on the side of the waterway plate, and the sterilization device is connected to the light guide plate through the first through hole; at least one first through hole is provided on a side of the waterway plate close to the water purification waterway; the waterway plate also includes at least one second through hole, and the second through hole is provided on a side of the waterway plate close to the water inlet waterway, and at least one sterilization device is connected to the light guide plate through the second through hole.
[0016] In the present solution, because the ultraviolet light will be lost to varying degrees when passing through the light guide plate, the first through hole and the second through hole are arranged at different positions, which helps to disperse the sterilization device, thereby avoiding the situation where the ultraviolet light intensity at the edge of the light guide plate far away from the first through hole or the second through hole is insufficient for sterilization. At the same time, multiple first through holes and second through holes are arranged, and multiple sterilization devices are arranged accordingly, which increases the amount of light entering, so that the inside of the waterway plate can be irradiated by ultraviolet rays of a certain intensity, thereby improving the sterilization effect.
[0017] Preferably, a plurality of sterilization devices are arranged in parallel on both sides of the light guide plate, wherein the light guide plate is provided with an extension portion at the edge, and the extension portion leads to the first through hole and / or the second through hole.
[0018] In this solution, multiple sterilization devices are arranged in parallel on both sides of the light guide plate, and an extension part is provided. The ultraviolet rays generated by the multiple sterilization devices are guided through the extension part, making the ultraviolet rays in the light guide plate more uniform, thereby achieving a better sterilization effect.
[0019] Preferably, the outline of the light guide plate is generated by the partition wall being offset outward by a preset value.
[0020] In this solution, the tension of the water flow is destroyed by the protruding light guide plate, which has a certain guiding effect on the water flow and reduces the probability of the existence of stagnant water in the water flow channel, thereby reducing the probability of colony formation.
[0021] Preferably, the offset is 1-1.5 mm; and the edge of the light guide plate is provided with a rounded corner.
[0022] In this solution, by adopting the above offset, it is possible to destroy the tension of the water flow while avoiding causing a large water resistance and avoiding damage to the light guide plate. At the same time, the edge of the light guide plate is provided with rounded corners, so that the ultraviolet rays can be scattered into the water flow channel along the rounded arc surface, and the water flow channel can be irradiated more evenly, thereby improving the sterilization effect.
[0023] Preferably, the waterway plate comprises a front shell and a rear shell, the light guide plate is sandwiched between the front shell and the rear shell, corresponding partition walls are arranged on the front shell and the rear shell, and the partition walls and the light guide plate are attached to form the water flow channel.
[0024] In this solution, a front shell and a rear shell are provided, and a partition wall and a light guide plate are bonded together to form a water flow channel structure, which has a simple structure and is easy to process and assemble.
[0025] The utility model also provides a water purifier, which is characterized in that the water purifier comprises a water outlet and a waterway plate assembly, and the waterway plate assembly is communicated with the water outlet.
[0026] In this solution, in a water purifier using the waterway plate assembly in this solution, the water outlet is connected to the waterway plate assembly, which reduces the number of colonies in the water outlet and improves the safety of the water purifier.
[0027] The positive progressive effect of the utility model is that by arranging a light guide plate in the waterway plate, the ultraviolet rays generated by the sterilization device can be irradiated to the water flow channel in the waterway plate through the light guide plate, and the entire water flow channel can be sterilized, thereby avoiding the formation of bacterial colonies in dead water areas. At the same time, the sterilization device is arranged outside the waterway plate, thereby avoiding damage to the sterilization device caused by the impact of water flow, thereby improving the safety of the waterway plate.

DETAILED DESCRIPTION
[0033] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.
[0034] like Figure 1 or Figure 2 As shown, this embodiment provides a waterway plate assembly 1, which includes a light guide plate 2, a sterilization device 3 and a waterway plate, wherein the waterway plate has a water flow channel 102 formed by a partition wall 101; the light guide plate 2 is arranged inside the waterway plate and laid on at least part of the partition wall 101; the sterilization device 3 is arranged outside the waterway plate and arranged close to the light guide plate 2, so that the sterilization device 3 generates ultraviolet rays that are irradiated into the water flow channel 102 through the light guide plate 2.
[0035] In this embodiment, by arranging the light guide plate 2 in the waterway plate, the ultraviolet rays generated by the sterilization device 3 can be irradiated to the water flow channel 102 in the waterway plate through the light guide plate 2, and the entire water flow channel 102 can be sterilized, thereby avoiding the formation of bacterial colonies in dead water areas. At the same time, the sterilization device 3 is arranged on the outside of the waterway plate and is not connected to the water flow channel 102, thereby avoiding the glass cover of the sterilization device 3 from being broken by the high pressure of the air inspection and water hammer test, thereby improving the safety of the waterway plate.
[0036] like Figure 1 As shown, adjacent partition walls 101 are arranged to form a water flow channel 102, wherein the partition walls 101 are a combination of straight lines and / or curves.
[0037] The water circuit board in the embodiment realizes the water purification function through components such as water inlet solenoid valve, booster pump, concentrated water solenoid valve, one-way valve and filter elements at various levels; the water circuit board realizes the sterilization function through the cooperation of the sterilization device 3 and the light guide plate 2, wherein the sterilization device 3 is an LED ultraviolet lamp.
[0038] like Figure 1-Figure 3 As shown, the plane where the light guide plate 2 in this embodiment is located is parallel to the plane where the plate body of the waterway plate is located, and the plane where the light guide plate 2 is located passes through the water flow channel 102 .
[0039] In this embodiment, the light guide plate 2 is arranged on the plane where the plate body of the waterway plate is located, which is convenient for installation inside the waterway plate. It can be arranged along the liquid flow direction in the waterway plate without affecting the water resistance in the water flow channel 102, thereby avoiding damage to the light guide plate 2 by water flow during long-term use.
[0040] like Figure 4 As shown, the water flow channel 102 in this embodiment includes an inlet waterway 4, a wastewater waterway 6 and a clean water waterway 5.
[0041] In a specific implementation, the coverage rate of the partition wall 101 of the light guide plate 2 on the clean water channel 5 is greater than the coverage rate of the partition wall 101 of the light guide plate 2 on the water inlet channel 4 or the waste water channel 6. The area where the water channel plate mainly needs to be sterilized is the clean water pipeline. Reducing the coverage rate of the light guide plate 2 on the partition wall 101 on the water inlet channel 4 and the waste water channel 6 can save the laying area of the light guide plate 2, thereby simplifying the structure. Furthermore, the coverage rate of the partition wall 101 of the light guide plate 2 on the clean water channel 5 is the highest, the coverage rate of the partition wall 101 on the water inlet channel 4 is the second highest, and the coverage rate of the partition wall 101 on the waste water channel 6 is the lowest.
[0042] Furthermore, the light guide plate 2 completely covers the purified water channel 5, and the water channel plate also covers at least part of the inlet water channel 4. This achieves sterilization of both the purified water channel 5 and the inlet water channel 4, thereby improving the sterilization effect.
[0043] like Figure 4 As shown, in this embodiment, the light guide plate 2 also covers the water inlet waterway 4 and the wastewater waterway 6, so as to achieve full-pipeline sterilization in the waterway plate, further improving the sterilization effect.
[0044] like Figure 1 or Figure 2 As shown, at least one first through hole 13 is provided on the side of the waterway plate in this embodiment, and the sterilization device 3 is connected to the light guide plate 2 through the first through hole 13; at least one first through hole 13 is provided on one side of the waterway plate close to the water purification channel 5.
[0045] In other embodiments, the waterway plate further includes at least one second through hole (not shown in the figure), the second through hole is arranged on one side of the waterway plate close to the water inlet waterway 4, and at least one sterilization device 3 is connected to the light guide plate 2 through the second through hole.
[0046] There will be different degrees of loss of ultraviolet light when passing through the light guide plate 2, so setting the first through hole 13 and the second through hole at different positions is helpful to disperse the sterilization device 3, so as to avoid the ultraviolet light intensity at the edge of the light guide plate 2 far away from the first through hole 13 or the second through hole being insufficient for sterilization. At the same time, multiple first through holes 13 and second through holes are set, and multiple sterilization devices 3 are set accordingly, which increases the amount of light entering, so that the inside of the waterway plate can be irradiated by ultraviolet rays of a certain intensity, thereby improving the sterilization effect.
[0047] like Figure 1 or Figure 2 As shown, a plurality of sterilization devices 3 in this embodiment are arranged in parallel on both sides of the light guide plate 2, wherein the light guide plate 2 is provided with an extension portion 21 at the edge, and the extension portion 21 leads to the first through hole 13 and / or the second through hole.
[0048] In this embodiment, a plurality of sterilization devices 3 are arranged in parallel on both sides of the light guide plate 2, and an extension portion 21 is provided. The extension portion 21 is used to guide the ultraviolet rays generated by the plurality of sterilization devices 3, so that the ultraviolet rays in the light guide plate 2 are more uniform, thereby achieving a better sterilization effect.
[0049] like Figure 4 As shown, the extension portion 21 is arranged on one side of the edge of the waterway plate close to the clean waterway 5 .
[0050] In other alternative embodiments, the number and positions of the sterilization devices 3 used are determined by actual sterilization tests. Since ultraviolet light will be lost to varying degrees when passing through the light guide plate 2, they can be placed in different positions so that the inside of the waterway plate can be irradiated by ultraviolet light of a certain intensity, further improving the sterilization efficiency.
[0051] like Figure 3 As shown, the outline of the light guide plate 2 in this embodiment is generated by the offset of the partition wall 101 outward by a preset value. The protruding light guide plate 2 destroys the tension of the water flow, has a certain guiding effect on the water flow, and reduces the probability of the existence of stagnant water in the water flow channel 102, thereby reducing the probability of colony formation.
[0052] like Figure 3 As shown, the offset in this embodiment is 1-1.5 mm; the edge of the light guide plate 2 is provided with a rounded corner 22 .
[0053] In this embodiment, when the offset is less than 1 mm, stagnant water in the water flow channel 102 cannot be avoided. When the offset is greater than 1 mm, the water resistance will increase, which will have a greater impact on the flow of the waterway plate and easily cause damage to the light guide plate 2. At the same time, the edge of the light guide plate 2 is provided with a rounded corner 22, which can make the ultraviolet rays scattered along the arc surface of the rounded corner 22 into the water flow channel 102, and can irradiate the water flow channel 102 more evenly, thereby improving the sterilization effect.
[0054] like Figure 1-Figure 3 As shown, the waterway plate in this embodiment includes a front shell 11 and a rear shell 12, the light guide plate 2 is clamped between the front shell 11 and the rear shell 12, and corresponding partition walls 101 are provided on the front shell 11 and the rear shell 12. The partition walls 101 on the front shell 11, the light guide plate 2 and the partition walls 101 on the rear shell 12 are sequentially attached to form a water flow channel 102.
[0055] In this embodiment, a front shell 11 and a rear shell 12 are provided, and a water flow channel 102 is formed by bonding a partition wall 101 and a light guide plate 2 . The structure is simple and easy to process and assemble.
[0056] In this embodiment, the light guide plate 2, the front shell 11 and the rear shell 12 are formed into a whole by ultrasonic welding.
[0057] This embodiment also provides a water purifier, which includes a water outlet and a waterway plate assembly 1, and the waterway plate assembly 1 is connected to the water outlet.
[0058] In this embodiment, in a water purifier using the waterway plate assembly 1 of this embodiment, the water outlet is connected to the waterway plate assembly 1, which reduces the number of colonies in water discharged from the water outlet and improves the safety of the water purifier.
[0059] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
