Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water purifiers, in particular to a water-vapor separation box. BACKGROUND

[0002] With the improvement of people's living standards, water purifiers are widely used. Due to different drinking water habits, some users like to drink normal temperature water, and some users like to drink hot water, so the water purifier integrating the functions of preparing normal temperature water and preparing hot water emerges as the times require, and the water-vapor separation box matching the water purifier also enters the public view.

[0003] The water purifier can generally heat and boil water, and when the water is boiled or close to the boiling state, a large amount of steam will be generated, which will mix with hot water and be discharged, which is easy to cause water flow interruption or floating, affecting the water discharge form. In order to solve the above problems, the water-vapor separation box is generally provided with a water-vapor separation chamber, which is provided with a normal temperature water inlet, a hot water inlet, an exhaust port and a water outlet passage. The hot water enters the hot water inlet and is separated from the generated steam in the water-vapor separation chamber. The hot water is discharged from the hot water outlet, and the steam is discharged from the exhaust port, thereby improving the water discharge form.

[0004] The discharge flow of normal temperature water is generally greater than that of hot water, and the water level in the water-vapor separation chamber during the normal temperature water discharge process is also higher than that during the hot water discharge process. The traditional water-vapor separation box has only one water outlet passage. When the normal temperature water is discharged, the water outlet passage is difficult to meet the large flow discharge, which is easy to cause the water-vapor separation box to be blocked. Therefore, in order to improve the above problems, the new water-vapor separation box on the market is provided with a small flow water outlet passage and a large flow water outlet passage. The inlet of the large flow water outlet passage is higher than that of the small flow water outlet passage. The hot water is discharged through the small flow water outlet passage, and the normal temperature water is discharged through the small flow water outlet passage and the large flow water outlet passage together, thereby improving the normal temperature water discharge flow. Although the above problems can be improved, the water-vapor separation box still has some defects, for example, although the large flow water outlet passage has a large water discharge space to meet the large flow discharge demand, the water gathering effect of the large space water discharge is poor, which causes the water flow to be unstable, bifurcate, and even have a shaking phenomenon. Therefore, the water discharge form in the large flow water outlet passage is not good, which is easy to splash outward, and it is also not convenient to pour water into a small container. CONTENT OF THE INVENTION

[0005] The present application provides a water-vapor separation box to improve the technical problems of unstable water flow, bifurcation, and even shaking of the large flow water outlet passage of the existing water-vapor separation box.

[0006] The technical scheme adopted by the present application is:

[0007] A water vapor separation box comprises a box body and a top cover, the top cover and the box body cooperate to form a water vapor separation cavity, the bottom of the box body is provided with an inner water outlet cylinder and an outer water outlet cylinder surrounding the inner water outlet cylinder, the inside of the inner water outlet cylinder forms a small-flow water outlet channel, and the outer water outlet cylinder and the inner water outlet cylinder form a large-flow water outlet channel; the water vapor separation box further comprises a water outlet cap connected with the outer water outlet cylinder, the lower end of the inner water outlet cylinder is exposed below the outer water outlet cylinder, and a water outlet gap for the large-flow water outlet channel to externally outlet water is formed between the lower end of the inner water outlet cylinder and the water outlet cap; the diameter of the water outlet gap is smaller than the inner diameter of the large-flow water outlet channel, so that the water outlet cap guides the water flow in the large-flow water outlet channel to flow towards the outer wall of the inner water outlet cylinder.

[0008] In the technical solution, when the small-flow water outlet channel and the large-flow water outlet channel jointly outlet water, the diameter of the water outlet gap is smaller than the inner diameter of the large-flow water outlet channel, so that the water outlet cap guides the water flow in the large-flow water outlet channel to flow towards the outer wall of the inner water outlet cylinder, and then the water flow in the large-flow water outlet channel is discharged downwards along the outer wall of the inner water outlet cylinder; the inner water outlet cylinder is located at the middle position of the outer water outlet cylinder, so that the water flow flowing along the outer wall of the inner water outlet cylinder converges at the middle of the large-flow water outlet channel, forms a water flow centering effect, stabilizes the water shape, and solves the problems of unstable water flow, bifurcation and shaking. Moreover, in the state that the small-flow water outlet channel and the large-flow water outlet channel jointly outlet water, a small water column is formed in the small-flow water outlet channel, and the water flow in the large-flow water outlet channel forms a large water column surrounding the small water column, thereby optimizing the water outlet shape.

[0009] The lower end of the water outlet cap is inwardly contracted to form a flow guide slope, and the flow guide slope and the inner water outlet cylinder enclose the water outlet gap; along the radial direction of the water outlet cap, the flow guide slope gradually inclines downwards from the periphery to the middle.

[0010] In the technical solution, the water outlet gap is enclosed by the flow guide slope and the inner water outlet cylinder, which is simple in structure and low in cost; the flow guide slope gradually inclines downwards from the periphery to the middle, which can better guide the dispersed water flow in the large-flow water outlet channel towards the outer wall of the inner water outlet cylinder, improve the water flow centering effect, and optimize the water outlet shape.

[0011] The flow guide slope is provided with a flow disturbance convex part located on the fluid path from the large-flow water outlet channel to the water outlet gap.

[0012] In the technical solution, the flow disturbance convex part disturbs the water flow on the flow guide slope, slows down the flow speed of the water flow, weakens the impact of the water flow on the inner water outlet cylinder, and enables the water flow in the large-flow water outlet channel to stably converge through the flow guide slope, and effectively prevents the water flow in the large-flow water outlet channel from impacting the water flow in the small-flow water outlet channel.

[0013] The spoiler convex part comprises a plurality of spoiler ribs arranged on the inner wall of the guide slope, and the plurality of spoiler ribs are arranged around the inner water outlet cylinder.

[0014] In the technical solution, the plurality of spoiler ribs form a ring structure, which improves the spoiler effect and sufficiently slows down the flow rate of the water flow on the guide slope.

[0015] The water-vapor separation box further comprises a mesh spoiler with mesh holes, which is located on the fluid path from the large-flow water outlet channel to the water outlet gap, so as to disturb the water flow in the large-flow water outlet channel.

[0016] In the technical solution, the mesh spoiler further slows down the flow rate of the water flow in the large-flow water outlet channel, weakens the water flow impact, stabilizes the water shape, and forms bubble water, so that the water outlet is more dense and soft.

[0017] The water-vapor separation box further comprises a flow regulator, which is arranged on the fluid path of the small-flow water outlet channel to regulate the water flow in the small-flow water outlet channel.

[0018] In the technical solution, the flow regulator regulates the water flow in the small-flow water outlet channel, stabilizes the water shape, reduces the shaking, and optimizes the water outlet form.

[0019] The flow regulator is a spring, and the inner diameter of the inner water outlet cylinder gradually decreases from top to bottom, and the inner diameter of at least a partial region is smaller than the diameter of the spring, so that the spring is limited in the small-flow water outlet channel.

[0020] In the technical solution, the spiral structure of the spring has a good flow regulating effect on the water flow, which can further optimize the water outlet form; the inner diameter of the inner water outlet cylinder gradually decreases from top to bottom, which has an effect of gathering the water flow in the middle of the small-flow water outlet channel to form a water column, avoiding bifurcation, and also limits the spring to prevent the spring from moving downward excessively and separating from the inner water outlet cylinder.

[0021] The water-vapor separation cavity is provided with a water separation rib, the water separation rib surrounds an overflow channel that connects the water-vapor separation cavity and the large-flow water outlet channel, and the inlet of the overflow channel is higher than the inlet of the small-flow water outlet channel.

[0022] In the technical solution, when the water outlet flow of the water-vapor separation box is small, the water is discharged through the small-flow water outlet channel; when the water outlet flow is large, when the water level exceeds the water separation rib, the water is discharged through the small-flow water outlet channel and the large-flow water outlet channel together.

[0023] The water-proof rib is arranged around the inlet of the small-flow water outlet channel, and is provided with a gap for avoiding water in the water-vapor separation cavity to flow into the small-flow water outlet channel.

[0024] In the technical solution, when the water flow of the water-vapor separation box is small, the water flow flows towards the small-flow water outlet channel through the gap, and needs to pass the water-blocking convex point in the flowing process. Therefore, the water-blocking convex point has a flow disturbing effect on the water flow entering the gap, so as to slow down the flow speed and make the water outlet of the small-flow water outlet channel more gentle.

[0025] The box body is provided with a slope, the high position of the slope is provided with a hot water inlet, the outer water outlet cylinder and the inner water outlet cylinder are arranged at the low position of the slope, the slope is provided with a gas discharge pipe and a water-blocking rib which protrude into the water-vapor separation cavity respectively, and the gas discharge pipe forms a gas discharge channel.

[0026] In the technical solution, the bottom wall of the water-vapor separation cavity is gradually inclined from the hot water inlet to the outer water outlet cylinder and the inner water outlet cylinder, so that when the water outlet is closed, the water flow in the water-vapor separation cavity can be quickly emptied, and the water-vapor separation box is prevented from dripping for a long time. In addition to discharging steam to achieve water-vapor separation, the gas discharge pipe can also block water together with the water-blocking rib to prevent water from overflowing and slow down the water flow speed.

[0027] Due to the adoption of the above technical solution, the technical effects achieved by the present application are as follows: when the small-flow water outlet channel and the large-flow water outlet channel are used to discharge water together, the diameter of the water outlet gap is smaller than the inner diameter of the large-flow water outlet channel, so that the water outlet cap guides the water flow in the large-flow water outlet channel to flow towards the outer wall of the inner water outlet cylinder, and the water flow along the outer wall of the inner water outlet cylinder is discharged downward. Since the inner water outlet cylinder is located at the middle position of the outer water outlet cylinder, the water flow along the outer wall of the inner water outlet cylinder converges at the middle of the large-flow water outlet channel, thereby forming a water flow centering effect, stabilizing the water shape, and solving the problems of unstable water flow, bifurcation and shaking. Moreover, in the state of discharging water by the small-flow water outlet channel and the large-flow water outlet channel together, a small water column is formed in the small-flow water outlet channel, and a large water column surrounding the small water column is formed in the large-flow water outlet channel, thereby optimizing the water discharge form.

[0049] In the embodiments of the present application, a water vapor separation box is provided, and the following description provided by the present application is based on the illustration of the product structure. Of course, those skilled in the art can understand that the above structure is only a specific example and illustrative description, and cannot constitute a specific limitation on the technical solutions provided by the present application.

[0050] Referring to Figures 1 to 7As shown, the water-vapor separation box provided by the application comprises a box body 1 and a top cover 2, the top cover 2 cooperates with the box body 1 to form a water-vapor separation cavity 3, the bottom of the box body 1 is provided with an inner water outlet cylinder 11 and an outer water outlet cylinder 12 surrounding the inner water outlet cylinder 11, the inside of the inner water outlet cylinder 11 forms a small-flow water outlet channel 13, and the outer water outlet cylinder 12 and the inner water outlet cylinder 11 form a large-flow water outlet channel 14; the water-vapor separation box further comprises a water outlet cap 4, the water outlet cap 4 is connected with the outer water outlet cylinder 12, the lower end of the inner water outlet cylinder 11 is exposed below the outer water outlet cylinder 12, and a water outlet gap 5 for the large-flow water outlet channel 14 to flow out water is formed between the lower end of the inner water outlet cylinder 11 and the water outlet cap 4, the diameter of the water outlet gap 5 is smaller than the inner diameter of the large-flow water outlet channel 14, so that the water flow in the large-flow water outlet channel 14 is guided by the water outlet cap 4 to flow towards the outer wall of the inner water outlet cylinder 11.

[0051] The water-vapor separation box of the application comprises a box body 1 and a top cover 2, forming a split design, which is convenient for processing and molding. Specifically, the box body 1 and the top cover 2 can be ultrasonically welded to ensure that the water-vapor separation cavity 3 has reliable sealing performance. In addition to being used for discharging hot water, the water-vapor separation box can also be used for discharging normal-temperature water. The water outlet cap 4 can fix the water-vapor separation box on a water purifier and also plays a decorative role. Specifically, the water outlet cap 4 can be threadedly connected with the outer water outlet cylinder 12 to improve the installation convenience.

[0052] In the technical solution, when the small-flow water outlet channel 13 and the large-flow water outlet channel 14 flow out water together, the diameter of the water outlet gap 5 is smaller than the inner diameter of the large-flow water outlet channel 14, so that the water flow in the large-flow water outlet channel 14 is guided by the water outlet cap 4 to flow towards the outer wall of the inner water outlet cylinder 11, and then the water flow in the large-flow water outlet channel 14 is discharged downwards along the outer wall of the inner water outlet cylinder 11. Since the inner water outlet cylinder 11 is located at the middle position of the outer water outlet cylinder 12, the water flow flowing along the outer wall of the inner water outlet cylinder 11 converges at the middle of the large-flow water outlet channel 14, forming a water flow centering effect, stabilizing the water shape, and solving the problems of unstable water flow, bifurcation and shaking. Moreover, in the state that the small-flow water outlet channel 13 and the large-flow water outlet channel 14 flow out water together, a small water column is formed in the small-flow water outlet channel 13, and the water flow in the large-flow water outlet channel 14 forms a large water column surrounding the small water column, thereby optimizing the water outlet shape.

[0053] As a preferred embodiment of the application, as shown in Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the lower end of the water outlet cap 4 is inwardly tapered to form a guide slope 41, and the guide slope 41 and the inner water outlet cylinder 11 enclose the water outlet gap 5. In the radial direction of the water outlet cap 4, the guide slope 41 gradually slopes downward from the outer periphery to the middle. In this technical solution, the water outlet gap 5 is enclosed by the guide slope 41 and the inner water outlet cylinder 11, which is simple in structure and saves cost. The water flow in the large-flow water outlet channel 14 flows from top to bottom and then hits the guide slope 41. Since the guide slope 41 gradually slopes downward from the outer periphery to the middle, it can better guide the dispersed water flow in the large-flow water outlet channel 14 towards the outer wall of the inner water outlet cylinder 11, improve the water flow centering effect, and optimize the water outlet form.

[0054] As a preferred embodiment, the guide slope 41 is provided with a turbulence protrusion, and the turbulence protrusion is located on the fluid path from the large-flow water outlet channel 14 to the water outlet gap 5. In this technical solution, the turbulence protrusion disturbs the water flow on the guide slope 41, slows down the water flow, and thus weakens the impact of the water flow on the inner water outlet cylinder 11, so that the water flow in the large-flow water outlet channel 14 flows smoothly through the guide slope 41 and converges, and the water flow in the large-flow water outlet channel 14 effectively prevents the water flow in the small-flow water outlet channel 13 from being impacted.

[0055] This embodiment does not specifically limit the structure of the turbulence protrusion. In a preferred example, as shown in Figures 3 to 5 The turbulence protrusion includes a plurality of turbulence ribs 42 spaced apart on the inner wall of the guide slope 41, and the plurality of turbulence ribs 42 are arranged around the inner water outlet cylinder 11. In this embodiment, the plurality of turbulence ribs 42 form a ring structure, the water flow on the guide slope 41 forms a wave-like flow state, and the plurality of turbulence ribs 42 form multiple turbulence effects, which improve the turbulence effect and sufficiently slow down the flow rate of the water flow on the guide slope 41. In other examples, the turbulence protrusion can also adopt other suitable structures, for example, the turbulence protrusion can include a plurality of protrusions arranged on the guide slope 41.

[0056] As a preferred embodiment, as shown in Figure 2 and Figure 3 The water-vapor separation box further includes a mesh turbulence member 6 with mesh holes, and the mesh turbulence member 6 is located on the fluid path from the large-flow water outlet channel 14 to the water outlet gap 5 to disturb the water flow in the large-flow water outlet channel 14. Specifically, the mesh turbulence member 6 can be clamped between the bottom end of the outer water outlet cylinder 12 and the guide slope 41 to avoid displacement of the mesh turbulence member 6. The turbulence effect of the mesh turbulence member 6 on the water flow in the large-flow water outlet channel 14 can further slow down the flow rate of the water flow, weaken the impact of the water flow, stabilize the water shape, and also form bubble water to make the water outlet more dense and soft.

[0057] As a preferred embodiment of the present application, as shown in Figure 2As shown, the water-vapor separation box further comprises a flow rectifier 7 arranged on the fluid path of the small-flow water outlet channel 13 to rectify the water flow in the small-flow water outlet channel 13, stabilize the water shape of the water flow in the water-vapor separation cavity 3 entering the small-flow water outlet channel 13, reduce the water flow shaking, and make the water flow not bifurcate, so as to make the water flow soft and optimize the water outlet shape.

[0058] As shown in the preferred embodiments, Figure 2 and Figure 3 the flow rectifier 7 is arranged as a spring, the inner diameter of the inner water outlet cylinder 11 gradually decreases from top to bottom, and the inner diameter of at least a part of the inner water outlet cylinder 11 is smaller than the diameter of the spring, so as to limit the spring in the small-flow water outlet channel 13. In the technical solution, the spiral structure of the spring has a good flow rectification effect on the water flow, which can further optimize the water outlet shape; the inner diameter of the inner water outlet cylinder 11 gradually decreases from top to bottom, which has an effect of gathering the water flow in the small-flow water outlet channel 13 to the middle part to form a water column, avoiding bifurcation, and also limits the spring, preventing the spring from moving downward excessively and separating from the inner water outlet cylinder 11. In other embodiments, the flow rectifier 7 can also adopt other suitable structures, for example, the flow rectifier 7 can also be a honeycomb flow rectification structure, a mesh flow rectification structure, etc.

[0059] As a preferred embodiment of the present application, as shown in Figure 2 , Figure 6 and Figure 7 the water-vapor separation cavity 3 is provided with a water separation rib 15, the water separation rib 15 surrounds an overflow channel 16 connecting the water-vapor separation cavity 3 and the large-flow water outlet channel 14, and the inlet of the overflow channel 16 is higher than the inlet of the small-flow water outlet channel 13. The overflow channel 16 constitutes a channel for the water-vapor separation cavity 3 to outlet water to the large-flow water outlet channel 14, when the water level in the water-vapor separation cavity 3 is lower than the water separation rib 15, the water outlet flow is small, and the water is discharged only through the small-flow water outlet channel 13; when the water level in the water-vapor separation cavity 3 exceeds the water separation rib 15, the water outlet flow is large, and the water is discharged through the small-flow water outlet channel 13 and the large-flow water outlet channel 14 together.

[0060] Further, as shown in Figure 7As shown, the water-blocking rib 15 is arranged around the inlet of the low-flow-rate water outlet channel 13. The water-blocking rib 15 has a clearance notch 17 for water to flow from the water vapor separation chamber 3 to the low-flow-rate water outlet channel 13. The clearance notch 17 has a water-blocking protrusion 18. In this technical solution, when the water flow rate of the water vapor separation box is small, the water flows through the clearance notch 17 toward the low-flow-rate water outlet channel 13. During the flow, it needs to pass through the water-blocking protrusion 18. Therefore, the water-blocking protrusion 18 has a turbulent effect on the water flow entering the clearance notch 17, thus slowing down the flow rate and making the water flow from the low-flow-rate water outlet channel 13 smoother.

[0061] As a preferred embodiment of this application, such as Figure 2 and Figure 6 As shown, the box body 1 is provided with a ramp 19. A hot water inlet 100 is located at the high position of the ramp 19, and the outlet water cylinder 12 and the inner outlet water cylinder 11 are located at the low position of the ramp 19. The ramp 19 is provided with an exhaust pipe 101 and a water-blocking rib 102 protruding into the water vapor separation chamber 3, respectively. An exhaust channel is formed in the exhaust pipe 101. In this technical solution, by gradually tilting the bottom wall of the water vapor separation chamber 3 downward from the hot water inlet 100 to the outlet water cylinder 12 and the inner outlet water cylinder 11, when water enters the hot water inlet 100, the bottom wall guides the water towards the outlet water cylinder 12 and the inner outlet water cylinder 11, pre-collecting the water in the water vapor separation chamber 3 near the outlet water cylinder 12 and the inner outlet water cylinder 11 to help the water flow out. In addition, when the water outlet is turned off, the water in the water vapor separation chamber 3 can be quickly emptied under the guiding effect of the bottom wall, avoiding prolonged dripping of water in the water vapor separation box. Hot water is separated into steam in the water-vapor separation chamber 3. The steam is discharged through the exhaust channel formed in the exhaust pipe 101, while the hot water is discharged through the small flow outlet channel 13 or through both the small flow outlet channel 13 and the large flow outlet channel 14. In addition to discharging steam and achieving water-vapor separation, the exhaust pipe 101, together with the water baffle 102, can also block water flow, prevent water from rushing, slow down the water flow velocity, and thus help optimize the water outlet pattern.
