Description

Technical Field

[0001] This utility model relates to the field of water dispenser technology, and more specifically, to a water dispenser and its pure water supply tank. Background Technology

[0002] Water dispensers, as a widely used point-of-use drinking water device, offer the core advantage of conveniently providing users with instant and safe drinking water. Modern water dispensers typically integrate efficient heating functions, and some models also have cooling functions to meet users' diverse needs for hot and cold water. To improve the continuity and response speed of water supply, some models are equipped with an independent pure water storage tank. This tank is usually used to temporarily store filtered pure water so that it can be quickly supplied when users need water, especially to meet the needs of instantaneous large-flow water dispensing or the stable water source requirements of heating systems.

[0003] In practice, it has been found that when the water level in the tank drops after the user finishes drawing water or during the system's automatic water replenishment process, the rapid discharge of water creates a local low-pressure area near the water outlet. This causes dissolved gases in the water to precipitate due to the reduced pressure, forming visible bubbles. At the same time, the turbulent water flow also carries in air, further aggravating the formation of bubbles. As a result, a large number of bubbles are easily generated and accumulated in the area near the water outlet. These bubbles, which form in the water tank and are discharged with the water flow, have a number of significant adverse effects on the performance of the water dispenser and the user experience. When the bubbles burst in the water pipes or heating chamber, they produce a noticeable "gurgling" or popping sound, which may be accompanied by slight vibrations. Furthermore, the introduction of a large number of bubbles can also lead to a decrease in the thermal efficiency of the instant heating element and an increase in energy consumption, affecting the continuity of hot water output and even causing the instant heating element to dry-burn, which has a significant impact on the user experience. Therefore, effectively suppressing the air bubbles generated in the water tank of a water dispenser during the drainage process has become a key technical challenge to improve the overall performance of the water dispenser, ensure its safety, optimize the user experience, and enhance the product's market competitiveness.

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

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Example Combination Figures 1-4 As shown, this embodiment provides a pure water supply tank for a water dispenser, comprising: Water outlet 110 is located at the bottom of water tank 100 and is used to connect water outlet pipe 106; A baffle 112 is provided at the bottom of the water tank 100 and above the outlet 110. The baffle 112 extends to cover and exceed the diameter of the outlet 110. A certain height of flow space is still formed between the baffle 112 and the outlet 110, and the baffle 112 separates the outlet 110 from the area directly above the flow space.

[0025] It should be noted that in practice, the water tank 100 is usually equipped with a power pump to supply pure water to the machine. When the liquid level in the tank is low, the continued pumping of water, along with the rapid discharge of water, can easily create a vortex in the area of ​​the outlet 110, introducing a large amount of air and further aggravating the generation of bubbles, which are then discharged through the outlet pipe 106. In this embodiment, a baffle 112 is designed at a certain height above the water outlet 110. The extension range of the baffle 112 can exceed and cover the aperture of the water outlet 110. In practice, the four edges of the baffle 112 extend at least 1 mm beyond the four edges of the water outlet 110, thereby blocking the formation path of the vortex directly above the water outlet 110. When the water flows downward to the position of the baffle 112, it is blocked by the baffle 112 and its flow direction is changed. It then flows downward to the water outlet 110 through the edge of the baffle 112. No new vortex will be formed in the area between the baffle 112 and the water outlet 110, which effectively alleviates the formation of vortex, avoids the introduction of a large amount of air and the further generation of bubbles, thereby effectively improving the user experience of the water dispenser.

[0026] In practice, the water tank 100 can be optionally configured so that its length is greater than the length and width of the tank body, i.e., its height dimension is larger. Within the limited installation space and tank volume, this helps to increase the liquid level inside the tank and also helps to mitigate the generation of vortices and bubbles. In practice, to ensure accurate detection of the liquid level inside the water tank 100, a liquid level detector, specifically a water level probe 104, is also installed inside the water tank 100 to detect the high, medium, and low water levels separately, so as to promptly grasp the water level information and replenish water in a timely manner.

[0027] To ensure timely water replenishment, the water tank 100 is also equipped with a water inlet a116, combined with... Figure 1 As shown, the preferred design is that the inlet a116 is located at the top of the water tank 100 for connecting the inlet pipe a102; the inlet a116 and the outlet 110 are located on the same side of the length direction of the water tank 100. Combined with... Figure 1 As shown in the orientation diagram, the left and right directions represent the length of the water tank 100. With the center point of this length direction as the boundary, both the inlet a116 and the outlet 110 are located on the left or right side of the water tank 100's length. Adopting a top-inlet and bottom-outlet design, the inlet and outlet 110 are located on the same side of the tank body, specifically near one end along the length of the tank. This allows for convenient concentrating of the piping on the same side when the water tank 100 is installed within the water dispenser, reducing the length of the piping and facilitating a compact installation.

[0028] More preferably, the water tank 100 is also provided with a water inlet b117, which is located at the top of the water tank 100 and is used to connect to the water inlet pipe b103; similarly, the water inlet b117 and the water outlet 110 are located on the same side along the length of the water tank 100. This dual water replenishment mode ensures rapid and effective water replenishment to the water tank 100.

[0029] To further explain, in this embodiment, a baffle 112 is provided above the outlet 110, which can also effectively protect the outlet 110 and reduce splashing bubbles. In practice, when the liquid level in the water tank 100 is low, water needs to be replenished in time through the inlet a116. The water flows directly from the top to the bottom, and the inlet and outlet are on the same side, which can easily cause the water to impact the outlet 110 area. Water splashing can also easily lead to the generation of bubbles. In practice, the water tank 100 can be replenished and discharged at the same time, that is, water is replenished and discharged at the same time. At this time, the bubbles formed in the outlet 110 area can easily be discharged directly from the outlet 110, resulting in more bubbles in the pipe.

[0030] In this embodiment, by setting baffle 112, not only is the formation of vortex at water outlet 110 blocked and the introduction of vortex bubbles reduced, but it can also cover and protect water outlet 110, which avoids the direct impact of water flow when replenishing water and reduces the formation of bubbles at water outlet 110 that directly enter water outlet 110, thus further alleviating the bubble problem in the water discharge process.

[0031] Furthermore, in practice, the baffle 112 can be selected to be coaxially distributed above the outlet 110, that is, the outlet 110 is located at the center below the baffle 112, and the horizontal width and length of the baffle 112 are both at least 1.5 times the diameter of the outlet 110, preferably between 1.5 and 3 times. Specifically, in practice, the horizontal width of the baffle 112 can be 1.5, 1.8, 2, 2.2, 2.5, 2.8, or 3 times the diameter of the outlet 110, etc., and the horizontal length can also be 1.5, 1.8, 2, 2.2, 2.5, 2.8, or 3 times the diameter of the outlet 110, etc., to ensure complete coverage of the top of the outlet 110 and mitigate vortex generation. Figure 3 As shown, the baffle 112 can be a rectangular or square flat plate, or a circular flat plate, or a non-flat plate such as a corrugated plate, etc. It will not be described in detail. The key is that it can fully cover the outlet 110 at an appropriate height and allow the water to flow through the side to the outlet 110.

[0032] Specifically, regarding the height design of the baffle 112, the preferred height between the baffle 112 and the outlet 110 is 5-25mm. In practice, using heights of 5mm, 10mm, 15mm, 18mm, 20mm, and 25mm not only creates a height interval that does not affect the water discharge after the flow reversal, but also effectively alleviates vortex formation and reduces the introduction of air bubbles. Furthermore, the design of the coverage area of ​​the baffle 112 prevents the formation of new vortices below the baffle 112, thus preventing the introduction of air bubbles and effectively mitigating the air bubble problem in the pipe. Correspondingly, in practice, the height of the water tank 100 is further controlled to 200-250mm, specifically 200mm, 220mm, 240mm, and 250mm.

[0033] Furthermore, in practice, it has been found that the formation of vortex is closely related to the water flow rate and the diameter of the outlet 110. This embodiment further optimizes the design by controlling the diameter of the outlet 110 to be 4-10mm, specifically 4mm, 5mm, 6mm, 8mm, 10mm, etc. A water pump 301 is installed on the water outlet pipe 106, and the pumping flow rate of the water pump 301 is controlled to be above 1L / min. This design effectively ensures the water flow rate, meets the user's need for a large flow rate and fast water output, and, in conjunction with the design of the baffle 112, reduces the problem of air bubble introduction.

[0034] Regarding the specific structure of the baffle 112, various implementation methods can be adopted, combined with Figure 3 As shown, the bottom of the preferred baffle 112 is provided with a downwardly extending support portion 113, and the bottom end of the support portion 113 is connected to the bottom of the water tank 100. More specifically, the baffle 112 has downwardly extending support portions 113 at both ends along its length. The bottom of the support portions 113 has outwardly extending fixing portions 114 that are fixedly installed at the bottom of the water tank 100, such as by bolts. Thus, the baffle 112 is arranged in a Z-shape and can be formed by bending a single sheet, which is convenient for processing and shaping. The support portions 113 at both ends provide stable support for the baffle 112, reducing impact deformation and ensuring stable coverage of the outlet 110. The other two sides of the baffle 112 are open, that is, the side edges of the support portions 113 at both ends are open. The diverted water flow connects to the outlet 110 through the open areas on both sides of the baffle 112. The open areas on both sides of the baffle 112 ensure that the water flow still flows fully to the outlet 110 after the diversion, without affecting the large flow of water, and without causing excessive cutting of the water flow, thus avoiding further generation of air bubbles.

[0035] In practice, the baffle 112 can also adopt other structural forms, such as using a single-sided support part 113 to support and fix the baffle 112, or using connecting columns to support both ends of the baffle 112, or fixing the end of the baffle 112 to the side wall of the water tank 100, etc., which will not be described in detail.

[0036] This embodiment also provides a water dispenser, which has a water tank 100 as described above. The top of the water tank 100 is connected to an inlet pipe, and the bottom is connected to an outlet pipe 106. An outlet pump 301 is provided on the outlet pipe 106, and the outlet pump 301 is used as a power source to supply pure water to the water dispenser body.

[0037] Furthermore, the water dispenser also includes a heating element 400 for heating the dispensed water. Optionally, the water tank 100 can be used as a pure water insulation tank, in which case the water outlet pipe 106 at the bottom of the water tank 100 is connected to the inlet end of the heating element 400, and the water pump 301 supplies water from the water tank 100 to the heating element 400; the top of the water tank 100 is provided with an inlet pipe a102 that is connected to the outlet of the heating element 400. In practice, a reversing valve can be installed at the outlet of the heating element 400. The first outlet of the reversing valve is connected to the faucet of the unit for direct hot water dispensing. The first outlet of the reversing valve is connected to the water tank 100 through the inlet pipe a102. The preheated water heated by the heating element 400 can be stored in the water tank 100 for heat preservation. When the preheated water is supplied to the heating element 400 for reheating by the outlet pump 301, the water temperature of the high-temperature water from the faucet can be ensured to be accurate, and the heating time of the heating element can be effectively reduced, meeting the user's demand for a large flow of hot water quickly. In addition, besides the outlet pipe 106, the inlet of the heating element 400 is also connected to another independent water supply pipe. Depending on the different water dispensing needs, it is possible to choose whether to use the preheated water in the water tank 100.

[0038] Furthermore, the machine body can also integrate a filtration function. The water dispenser also includes a filter module 500. The purified water outlet of the filter module 500 is connected to the inlet of the heating element 400 through a pipe. This pipe is another independent water supply pipe for the heating element 400, and the purified water can be directly supplied to the heating element 400. Preferably, the water inlet b117 at the top of the water tank 100 is also connected to an inlet pipe b103. The purified water outlet of the filter module 500 is also connected to the water tank 100 through the inlet pipe b103. That is, the purified water from the filter module 500 can be directly supplied to the heating element 400 or directly replenished to the water tank 100 through different pipes. In practice, control valves are installed on both the pipe and the inlet pipe b103 to control the opening and closing of different pipes. Using the inlet pipe B103 to quickly replenish room temperature water can ensure the liquid level in the tank and avoid a sharp drop in water volume when the heating element 400 produces hot water if the water volume is seriously insufficient. In addition, the rapid replenishment and increase of the liquid level also further alleviates the problems of vortex and air bubbles when water is rapidly produced at low liquid levels.

[0039] Combination Figure 1 and Figure 3As shown, the water tank 100 has a top cover 101 and a bottom wall 115. Preferably, inlet pipes a102 and b103 are both located on the top cover 101, and outlet pipes 110 and 106 are both located on the bottom wall 115. Furthermore, inlet pipes a102 and b103, and outlet pipe 110, are all located on the same side along the length of the water tank 100. When used as an insulated tank, the top-filling and bottom-outlet water method promotes automatic heat circulation and mixing of hot and cold water within the tank, ensuring sufficient and uniform water temperature mixing. It also ensures that preheated water at the bottom is preferentially discharged when water is used, meeting the hot water temperature requirements.

[0040] In practice, the top cover 101 of the water tank 100 is also equipped with an exhaust pipe 105 to allow the water tank 100 to communicate with the outside atmosphere. Further optionally, the bottom wall 115 of the water tank 100 is also equipped with a drain outlet 109 and a drain pipe 107, with a sealing plug installed on the drain pipe 107. During normal use, the drain pipe 107 is closed, and water is supplied externally via the outlet pipe 106; when not in use for a long time or when necessary, the outlet pipe 106 can also be closed, allowing stagnant water in the tank to be discharged externally through the drain pipe 107. A bracket 108 can also be installed on the bottom wall 115 of the water tank 100 to further stabilize the tank. A temperature sensor 111 can also be installed inside the water tank 100 to monitor the water temperature in real time.

[0041] Combination Figure 4 To further optimize the arrangement of the heating element 400 and the water tank 100 within the machine body, the heating element 400 and the water tank 100 are further distributed along the length of the machine body at both ends, with a water channel installation area 300 between the heating element 400 and the water tank 100, and the water pump 301 is located within the water channel installation area 300; correspondingly, the water inlet pipe and the water outlet pipe 106 of the water tank 100 are both located on the side close to the water channel installation area 300.

[0042] In practice, both the heating element 400 and the water tank 100 used for hot water insulation are high-temperature components inside the machine. Separating them at both ends of the machine's length creates a high-temperature zone, and the gap between them is used to install the required water pipes, valve groups, pump groups, and other low-temperature water circuit structures. This avoids excessive concentration of high-temperature zones, prevents heat accumulation that is difficult to dissipate, and avoids affecting the precise control of the water temperature at the pipe outlet. Furthermore, the water circuit installation area 300 is located between the heating element 400 and the water tank 100, which also facilitates the centralized distribution and disassembly of the required pipes, valve groups, and pump groups, effectively reducing pipe distribution and optimizing the compact layout inside the machine.

Thanks to the teachings of this utility model, those skilled in the art will readily recognize that alternative structures to the disclosed structure can be used as feasible alternative implementations, and that the disclosed implementations can be combined to produce new implementations, which also fall within the scope of the appended claims.
