Description

Technical Field

[0001] The present application relates to the technical field of instant heating equipment, and in particular to a water vapor separation box. Background Art

[0002] Instant heating technology offers the advantages of on-demand heating and energy conservation, and is therefore applicable to water purification / drinking devices with heating functions, such as instant water dispensers. Existing instant water heating devices can boil water before dispensing it. However, when water is heated to a high temperature, it is often accompanied by water vapor. The higher the temperature, the more water vapor there is. For smaller water flow rates, the excess water vapor can cause the water to stop flowing or float, affecting the appearance of the water.

[0003] To solve the above problems, most of the current instant hot water drinking equipment drains water through a water vapor separation box. The water vapor separation box is provided with a water discharge path and a steam discharge path. Hot water and steam are separated in the water vapor separation box to improve the water outlet shape. Among them, the inlet of the steam discharge path is higher than the inlet of the water discharge path to reduce the risk of water entering the steam discharge path.

[0004] Instant hot water drinking equipment generally uses a water vapor separation box for drainage of cold and hot water, and the cold water outlet flow rate is usually larger than the hot water outlet flow rate. In order to prevent the cold water from filling the water vapor separation box and overflowing from the steam discharge path when the cold water outlet flow rate is large, the water vapor separation box is usually designed with a relatively large cavity, so as to avoid the water flow filling the water vapor separation box when the water outlet flow rate is large as much as possible. However, this also brings some defects. For example, a larger water vapor separation box will temporarily retain more water after the water outlet is completed. This part of the retained water will affect the temperature of the next hot water outlet. Even if the water outlet is set at the lowest position of the water vapor separation box so that this part of the stored water can flow toward the water outlet and be discharged under the action of gravity, the water volume is large and the flow is slow, resulting in a long drainage time. After the user presses the stop water outlet button, water will still flow from the water outlet for a period of time, affecting the user experience. Utility Model Content

[0009] An exhaust port and an air guide pipe surrounding the exhaust port and extending upward are provided on the bottom wall of the high-position water inlet cavity, and an air gap is formed between the top end of the air guide pipe and the top cover.

[0010] The top cover is provided with a concave cavity formed by being recessed upwards, and the air guide pipe extends into the concave cavity and forms an air intake gap communicating with the air passage gap with the side wall of the concave cavity.

[0011] The air guide tube is located in the center of the cavity, and the width of the air intake gap is set to d, where 0.5 mm

[0012] The air guide tube is provided with an outwardly protruding air guide rib, which extends spirally downward from the top of the air guide tube; or, the part of the air guide tube extending into the concave cavity is provided with an outwardly protruding water retaining platform, and multiple water retaining platforms are arranged along the axial direction of the air guide tube.

[0013] A diversion water retaining rib extending upward to abut the top cover is provided on the bottom wall of the high-position water inlet cavity. The diversion water retaining rib has a V-shaped structure. The water inlet is provided on the side away from the V-shaped opening of the diversion water retaining rib, and the air guide pipe is provided in the V-shaped opening of the diversion water retaining rib.

[0014] The bottom wall of the water-guiding cavity is provided with an upwardly extending bypass structure, and the bypass structure forms a bypass channel, one end of the bypass channel opens toward the water inlet, and the other end of the bypass channel opens toward the water outlet, and the width of at least part of the bypass channel gradually decreases from one end close to the water inlet to the other end close to the water outlet.

[0015] The bypass structure includes a plurality of bypass rib groups arranged at intervals between the water inlet and the water outlet, the bypass rib group includes two bypass ribs, and the width of the bypass channel surrounded by the two bypass ribs gradually decreases along the direction of the water inlet pointing to the water outlet. A V-shaped water guide rib is provided between two adjacent bypass rib groups, and the V-shaped opening of the V-shaped water guide rib faces the water outlet.

[0016] The water outlet is arranged on the bottom wall of the low-level water outlet cavity, and the water outlet includes a low-level water outlet and a high-level water outlet distributed on at least one side of the low-level water outlet. The bottom wall is provided with a water pipe surrounding the high-level water outlet and extending upward, and the top end of the water pipe is lower than the top cover and higher than the low-level water outlet.

[0017] A drainage column extending in a vertical direction is provided in the center of the low-position water outlet, and the drainage column is evenly connected to the inner wall of the low-position water outlet through a plurality of first drainage ribs along the circumference, and the thickness of the first drainage ribs gradually decreases toward the drainage column; and / or, a plurality of second drainage ribs arranged at intervals along the circumference of the low-position water outlet are provided in the high-position water outlet, and the second drainage ribs extend radially along the low-position water outlet, and the thickness of the second drainage ribs gradually decreases toward the low-position water outlet.

[0018] Due to the adoption of the above technical solution, the technical effects achieved by this application include at least:

[0019] 1. The water vapor separation box provided in the present application has a lower water outlet chamber that is lower than the higher water inlet chamber. The lower water outlet chamber and the higher water outlet chamber are connected by an inclined water guide chamber. The water inlet is provided in the higher water inlet chamber, and the water outlet is provided in the lower water outlet chamber. After the water flows into the higher water inlet chamber through the water inlet, it flows into the lower water outlet chamber under the guidance of the water guide chamber and is finally discharged from the water outlet. The water vapor separation box is a relatively thin high-low step-like structure, which helps to reduce the height of the water vapor separation chamber in the vertical direction. After the user presses the stop water outlet button of the drinking water device, the drinking water device stops supplying water to the water vapor separation box. The thinner water vapor separation chamber retains less water, and under the guidance of the inclined water guide chamber, the water flows quickly out of the water outlet. The water level in the water vapor separation chamber drops rapidly, causing the water outlet to stop discharging water in a very short time, thereby helping the drinking water device to achieve one-button water stop and stop water immediately after turning off the water, thereby improving the user experience. After the water in the water vapor separation chamber is emptied, no residual water will remain, which will not affect the temperature of the next hot water output.

[0020] 2. As a preferred embodiment of the present application, the exhaust port is provided on the bottom wall of the high-position water inlet chamber, and an air duct is provided around it. An air gap is formed between the top of the air duct and the top cover, so that the steam generated when the water vapor separation chamber discharges hot water enters the air duct through the air gap and then is discharged from the water vapor separation box through the exhaust port. Compared with setting the exhaust port in the water guide chamber or the low-position water outlet chamber, this solution sets the exhaust port in the high-position water inlet chamber, which is located at a higher position in the water vapor separation chamber. Since the water entering the high-position water inlet chamber will quickly flow to the low-position water outlet chamber under the guidance of the water guide chamber, even if a large amount of water is discharged, the water level in the high-position water inlet chamber will generally be at a relatively low state, thereby effectively preventing water from overflowing into the air duct, ensuring that water vapor separation can be reliably achieved when discharging hot water, and guiding the steam to be discharged through the air duct.

[0021] 3. As a preferred embodiment of the present application, the top cover is provided with a concave cavity formed by an upward depression, and the air duct extends into the concave cavity and forms an air inlet gap connected to the air gap with the side walls of the concave cavity. Through this design, the high-position water inlet cavity can be made as thin as possible to reduce the amount of water stored when drainage is stopped, and the air duct can be extended into the concave cavity to increase the position of the air gap as much as possible, thereby reducing the risk of water overflowing from the air gap into the air duct.

[0022] 4. As a preferred embodiment of the present application, the air duct is provided with a spirally extending air rib or water retaining platform. While ensuring that steam can enter the air duct through the air intake gap, the air rib or water retaining platform can also be used to increase the contact area between the air duct and the steam, which helps the steam to condense in the air intake gap, and the condensed water formed flows downward along the air rib or water retaining platform. In addition, the air rib or water retaining platform can also be used to increase the difficulty of the water flow in the water vapor separation chamber to enter the air duct, further reducing the risk of water overflowing into the air duct from the air gap.

[0023] 5. As a preferred embodiment of the present application, the diverter water retaining rib has a V-shaped structure, the water inlet is arranged on the side of the V-shaped opening away from the diverter water retaining rib, and the air guide pipe is arranged in the V-shaped opening of the diverter water retaining rib. When water enters the water vapor separation box through the water inlet, it first collides with the diverter water retaining rib. If hot water enters, the collision process helps to accelerate the separation of water vapor and reduce the kinetic energy of the water. If cold water enters, the collision process greatly reduces the kinetic energy of the cold water, so that the water flows more smoothly to the water outlet, and the water has a better shape when flowing out of the water outlet. The water volume at the water outlet will not increase or decrease sharply, which helps to improve the user experience; the air guide pipe is arranged in the V-shaped opening of the diverter water retaining rib, so that the water flow is diverted to both sides of the air guide pipe by the diverter water retaining rib, reducing the risk of water flow entering the air guide pipe.

[0024] 6. As a preferred method of the present application, by setting a bypass structure in the water-guiding cavity, the hot water entering the water-guiding cavity will bypass in the bypass channel, which helps to accelerate the separation of water vapor. The cold water entering the water-guiding cavity can also reduce the kinetic energy through the bypass to improve the water type of the outlet water.

[0025] 7. As a preferred embodiment of the present application, the water outlet includes a low-level water outlet and a high-level water outlet. The water pipe surrounds the high-level water outlet and extends upward. The top of the water pipe is lower than the top cover and higher than the low-level water outlet. When the water flow rate is small, the water level in the water vapor separation chamber is low, and water is discharged from the low-level water outlet, so that even small-flow water is easily gathered in the middle to form a beam of water; when the water flow rate is large, the water level in the water vapor separation chamber is high, and water is discharged from the low-level water outlet and the high-level water outlet at the same time, avoiding the water level in the water vapor separation chamber being too high and overflowing from the exhaust port.

[0039] In order to more clearly illustrate the overall concept of the present application, a detailed description is given below in an illustrative manner in conjunction with the accompanying drawings.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0042] In this application, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0043] Throughout this specification, reference to terms such as "one embodiment," "some embodiments," "examples," "specific examples," or "some examples" means that a specific feature, structure, material, or characteristic described in conjunction with that embodiment or example is included in at least one embodiment or example of the present application. Throughout this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0044] In the embodiments of this application, a water vapor separation box is provided. For ease of explanation and understanding, the following content provided in this application is based on the illustrated product structure. Of course, those skilled in the art will understand that the above structure is only a specific example and schematic description and does not constitute a specific limitation of the technical solution provided in this application.

[0045] like Figures 1 to 6As shown, the present application provides a water vapor separation box, comprising a box body 1 and a top cover 2 provided on the top of the box body 1, the box body 1 and the top cover 2 forming a water vapor separation chamber 3, the box body 1 being provided with a water inlet 11 and a water outlet 12 respectively connected to the water vapor separation chamber 3, the water vapor separation chamber 3 comprising a high-position water inlet chamber 31, a low-position water outlet chamber 32, and a water guide chamber 33 located between the high-position water inlet chamber 31 and the low-position water outlet chamber 32, the water guide chamber 33 gradually tilting downward from one end connected to the high-position water inlet chamber 31 to the other end connected to the low-position water outlet chamber 32, the water inlet 11 being provided in the high-position water inlet chamber 31, and the water outlet 12 being provided in the low-position water outlet chamber 32. In a preferred embodiment, to ensure the sealing performance of the water vapor separation chamber 3, the box body 1 and the top cover 2 can be fastened and sealed together by welding.

[0046] The water vapor separation box provided in the present application has a low-level water outlet chamber 32 that is lower than the high-level water inlet chamber 31 as a whole, and the two are connected through an inclined water guide chamber 33. The water inlet 11 is set in the high-level water inlet chamber 31, and the water outlet 12 is set in the low-level water outlet chamber 32. After the water flows into the high-level water inlet chamber 31 through the water inlet 11, it flows into the low-level water outlet chamber 32 under the guidance of the water guide chamber 33, and is finally discharged from the water outlet 12. The water vapor separation box has a relatively thin, stepped structure, which helps reduce the vertical height of the water vapor separation chamber 3. For drinking water equipment, when the user presses the stop button on the drinking water equipment, the water source within the drinking water equipment stops supplying water to the water vapor separation box. The thinner water vapor separation chamber 3 retains less water, and under the guidance of the inclined water guide chamber 33, the water quickly drains out of the water outlet 12. The water level within the water vapor separation chamber 3 drops rapidly, causing the water outlet 12 to stop discharging water in a very short time. This helps the drinking water equipment achieve a one-click water stop or shut-off function, improving the user experience. After the water vapor separation chamber 3 is emptied, no residual water remains, which does not affect the temperature of the next hot water outlet. In a preferred embodiment, the water guide chamber 33 can be tilted at an angle of not less than 30° relative to the horizontal plane to increase the flow rate of the water as it flows from the high-level water inlet chamber 31 to the low-level water outlet chamber 32, effectively improving the speed at which the water in the water vapor separation chamber 3 is cleared after water discharging stops.

[0047] Further, if Figure 2 、 Figure 3 and Figure 6As shown, the bottom wall of the high-position water inlet chamber 31 is provided with an exhaust port 13 and an air guide pipe 14 surrounding the exhaust port 13 and extending upward, with an air gap 4 formed between the top end of the air guide pipe 14 and the top cover 2. Those skilled in the art will appreciate that the exhaust port 13 is provided on the bottom wall of the high-position water inlet chamber 31 and is surrounded by the air guide pipe 14, forming an air gap 4 between the top end of the air guide pipe 14 and the top cover 2, so that steam generated when hot water is discharged from the water vapor separation chamber 3 passes through the air gap 4, enters the air guide pipe 14, and then exits the water vapor separation box through the exhaust port 13. Compared with setting the exhaust port 13 in the water guide chamber 33 or the low-level water outlet chamber 32, this solution sets the exhaust port 13 in the high-level water inlet chamber 31, which is located at a higher position in the water vapor separation chamber 3. Since the water entering the high-level water inlet chamber 31 will flow quickly to the low-level water outlet chamber 32 under the guidance of the water guide chamber 33, even if a large amount of water is discharged, the water level in the high-level water inlet chamber 31 will generally be at a relatively low state, thereby effectively preventing water from overflowing into the air guide pipe 14, ensuring that water vapor separation can be reliably achieved when discharging hot water, and guiding the steam to be discharged through the air guide pipe 14.

[0048] In a preferred embodiment, Figure 2 、 Figure 4 and Figure 6 As shown, the top cover 2 is provided with an upwardly concave cavity 21, and the air duct 14 extends into the cavity 21 and, together with the sidewalls of the cavity 21, forms an air intake gap 5 that is connected to the air gap 4. Those skilled in the art will appreciate that the top cover 2 is provided with an upwardly concave cavity 21, and the air duct 14 extends into the cavity 21 and, together with the sidewalls of the cavity 21, forms an air intake gap 5 that is connected to the air gap 4. This design not only allows the high-position water inlet chamber 31 to be made as thin as possible to reduce the amount of water retained when drainage is stopped, but also allows the air duct 14 to be extended into the cavity 21 to raise the position of the air gap 4 as much as possible, thereby reducing the risk of water overflowing from the air gap 4 into the air duct 14.

[0049] More preferably, Figure 2 and Figure 6 As shown, the air duct 14 is located in the center of the concave cavity 21, and the width of the air intake gap 5 is set to d, where 0.5mm≤d≤1mm, so that steam can easily enter the air duct 14 through the air intake gap 5 for discharge, while water cannot easily enter the air duct 14 through the air intake gap 5, so as to prevent water from overflowing from the exhaust port 13.

[0050] In a preferred embodiment, Figure 2 and Figure 3As shown, the air guide pipe 14 is provided with an outwardly protruding air guide rib 141, and the air guide rib 141 extends spirally downward from the top of the air guide pipe 14. When the water vapor separation box discharges hot water, the water vapor separation causes the steam to enter the air inlet gap 5, and after spirally rising along the air guide rib 141, it passes through the air gap 4 and enters the air guide pipe 14. While ensuring that the steam can enter the air guide pipe 14 through the air inlet gap 5, the air guide rib 141 can also be used to increase the contact area between the air guide pipe 14 and the steam, which helps the steam to condense in the air inlet gap 5, and the condensed water formed flows downward along the air guide rib 141. In addition, the air guide rib 141 can also be used to increase the difficulty of the water flow in the water vapor separation chamber 3 entering the air guide pipe 14, further reducing the risk of water overflowing from the air gap 4 into the air guide pipe 14. In an alternative embodiment, as Figure 5 and Figure 6 As shown, the air guide rib 141 can be replaced by a water retaining platform 142. Specifically, the portion of the air guide tube 14 extending into the concave cavity 21 is provided with a water retaining platform 142 protruding outward, and multiple water retaining platforms 142 are arranged along the axial direction of the air guide tube 14. The water retaining platform 142 can achieve the same effect as the air guide rib 141, promoting the condensation of steam in the air intake gap 5 and preventing water from entering the air guide tube 14.

[0051] As a preferred embodiment, Figure 2 and Figure 3 As shown, a diverter water retaining rib 15 extending upward to abut the top cover 2 is provided on the bottom wall of the high-position water inlet chamber 31, and the diverter water retaining rib 15 is in a V-shaped structure. The water inlet 11 is provided on the side of the V-shaped opening away from the diverter water retaining rib 15, and the air guide pipe 14 is provided in the V-shaped opening of the diverter water retaining rib 15. Those skilled in the art can understand that the diverter water retaining rib 15 has a V-shaped structure, the water inlet 11 is arranged on the side of the V-shaped opening away from the diverter water retaining rib 15, and the air guide pipe 14 is arranged in the V-shaped opening of the diverter water retaining rib 15. When water enters the water vapor separation box through the water inlet 11, it first collides with the diverter water retaining rib 15. If hot water enters, the collision process helps to accelerate the separation of water vapor and reduce the kinetic energy of the water. If cold water enters, the collision process greatly reduces the kinetic energy of the cold water, so that the water flows more smoothly when it flows to the water outlet 12, and the water has a better shape when flowing out of the water outlet 12. The amount of water at the water outlet 12 will not increase or decrease suddenly, which helps to improve the user experience; the air guide pipe 14 is arranged in the V-shaped opening of the diverter water retaining rib 15, so that the water flow is diverted by the diverter water retaining rib 15 toward both sides of the air guide pipe 14, reducing the risk of water flow entering the air guide pipe 14.

[0052] As a preferred embodiment of the present application, Figure 3As shown, the bottom wall of the water-guiding cavity 33 is provided with an upwardly extending bypass structure 16. The bypass structure 16 forms a bypass channel, one end of which opens toward the water inlet 11 and the other end of which opens toward the water outlet 12. The width of at least a portion of the bypass channel gradually decreases from the end near the water inlet 11 to the other end near the water outlet 12. The bypass structure 16 forms a bypass channel, and hot water entering the water-guiding cavity 33 will circulate within the bypass channel. Since the width of at least a portion of the bypass channel gradually decreases from the end near the water inlet 11 to the other end near the water outlet 12, the circulation area of ​​the hot water within the bypass channel is reduced, thereby reducing the flow rate of the hot water within the bypass channel and facilitating the separation of as much water vapor as possible within the bypass channel. In addition, when cold water with a higher flow rate enters the bypass channel, the kinetic energy can be reduced by the bypass flow, thereby improving the water type when the cold water is discharged at the water outlet 12.

[0053] Regarding the specific form of the flow-around structure 16, in a preferred embodiment, as shown in FIG. Figure 3 As shown, the bypass structure 16 includes a plurality of bypass rib groups arranged at intervals between the water inlet 11 and the water outlet 12, and the bypass rib group includes two bypass ribs 161. The width of the bypass channel surrounded by the two bypass ribs 161 gradually decreases along the direction of the water inlet 11 pointing to the water outlet 12, and a V-shaped water guide rib 162 is provided between two adjacent bypass rib groups, and the V-shaped opening of the V-shaped water guide rib 162 faces the water outlet 12. Figure 3 The figure schematically illustrates an embodiment in which the bypass structure 16 includes two bypass rib groups, with a V-shaped water guide rib 162 provided between the two bypass rib groups. Along the flow direction of the water from the water inlet 11 toward the water outlet 12, the water first enters a group of bypass rib groups close to the water inlet 11, and gradually converges and flows out between the two bypass ribs 161 in a decelerated state, then hits the V-shaped water guide rib 162, and is dispersed to both sides through the V-shaped water guide rib 162, and then enters between the two bypass ribs 161 of the next group of bypass rib groups and continues to gradually converge and flow out in a decelerated state. Therefore, the water flows in the bypass channel in a manner of first converging, then dispersing, and then converging again, effectively promoting water vapor separation and reducing kinetic energy.

[0054] As a preferred embodiment of the present application, Figure 3As shown, the water outlet 12 is arranged on the bottom wall of the low-level water outlet cavity 32, and the water outlet 12 includes a low-level water outlet 121 and a high-level water outlet 122 distributed on at least one side of the low-level water outlet 121. The bottom wall is provided with a water pipe 17 surrounding the high-level water outlet 122 and extending upward, and the top end of the water pipe 17 is lower than the top cover 2 and higher than the low-level water outlet 121. Those skilled in the art will appreciate that, with this design, for drinking water equipment, when the water flow rate of the drinking water equipment is controlled to be small, the water level of the water flow entering the water vapor separation chamber 3 is low and does not overflow the top of the water pipe 17. Therefore, water is only discharged from the low-level water outlet 121, so that small-flow water can also easily gather in the middle of the low-level water outlet 121 to form a beam of water; when the water flow rate of the drinking water equipment is controlled to be large, the water level in the water vapor separation chamber 3 is high and overflows the top of the water pipe 17, and water is discharged from both the low-level water outlet 121 and the high-level water outlet 122, thereby increasing the displacement of the water outlet 12, which helps to avoid a large amount of water entering the water vapor separation chamber 3, causing the water level to be too high and overflowing from the exhaust port 13.

[0055] In a preferred embodiment, if Figure 2 and Figure 3 As shown, a drainage column 18 extending in the vertical direction is provided in the center of the low-position water outlet 121. The drainage column 18 is evenly connected to the inner wall of the low-position water outlet 121 through multiple first drainage ribs 191 along the circumference. The thickness of the first drainage ribs 191 gradually decreases toward the drainage column 18. Through this arrangement, the water flow entering the low-position water outlet 121 can form a Coanda effect. According to the Coanda effect, the water in the low-position water outlet 121 will flow toward the drainage column 18 along the surface of the first drainage rib 191, so that the water gathers at the middle drainage column 18 and then flows downward, further improving the water flow pattern of the low-position water outlet 121. The first drainage rib 191 not only has the function of fixing the drainage column 18 in the central position, but also has the function of guiding the water flow to the middle drainage column 18.

[0056] In a preferred embodiment, if Figure 2 and Figure 3 As shown, the high-level water outlet 122 is provided with a plurality of second drainage ribs 192 spaced circumferentially along the low-level water outlet 121. The second drainage ribs 192 extend radially along the low-level water outlet 121, and the thickness of the second drainage ribs 192 gradually decreases toward the low-level water outlet 121. This arrangement allows the water flow entering the high-level water outlet 122 to form a Coanda effect. According to the Coanda effect, the water in the high-level water outlet 122 flows along the surface of the second drainage ribs 192 toward the outer wall of the low-level water outlet 121, causing the water to gather on the outer wall of the low-level water outlet 121 and then flow downward, further improving the water flow pattern of the high-level water outlet 122.
