The invention provides a water-vapor separation device which is applied to a water dispenser, wherein the water dispenser has a low-flow high-temperature water outlet mode and a high-flow low-temperature water outlet mode.
In an embodiment of the present invention, as shown in fig. 1, the water-vapor separation device includes a housing 100 and an exhaust opening and closing assembly, a water inlet 110 and a water outlet 120 are disposed at a lower portion of the housing 100, an exhaust opening 130 is disposed at an upper portion of the housing 100, the water inlet 110 is connected to a water outlet pipe of a water tank of the water dispenser, the water outlet pipe is configured to output high-temperature water in a low-flow high-temperature water outlet mode, output normal-temperature water or low-temperature water in a high-flow low-temperature water outlet mode, the water outlet 120 is configured to output water, and the exhaust opening 130 is configured to exhaust steam; the air outlet switch component is used for opening the air outlet in a low-flow high-temperature water outlet mode, when the water outlet requirement is low-flow high-temperature water outlet, the air outlet 130 is opened, water vapor is discharged from the air outlet 130, high-temperature boiling water is discharged from the water outlet 120, the high-temperature boiling water is separated from the water vapor, and the phenomenon that the water vapor and the water vapor drive a drifting high-temperature boiling water column to cause burn is avoided; the air outlet switch component is also used for closing the air outlet 130 in a large-flow low-temperature water outlet mode so as to form a pressurized air cavity for improving the water outlet flow on the upper part of the shell 100, when the water inlet speed of the water inlet 110 is greater than the water outlet speed of the water outlet 120, namely the water outlet requirement is large-flow low-temperature water outlet, the air outlet 130 is closed, the water level in the shell 100 is gradually raised, the air pressure on the upper part of the shell 100 is increased, the water outlet speed of the water outlet 120 is increased, the air outlet 130 is closed when the large-flow low-temperature water outlet is carried out, and the problem that the water in the shell 100 overflows from the air outlet 130 is avoided.
According to the technical scheme, the exhaust port 130 is opened through the exhaust port switch assembly in a low-flow high-temperature water outlet mode, high-temperature steam is separated from high-temperature water, and burns caused by the steam and a high-temperature boiling water column driven by the steam to float are avoided; and the air outlet 130 is closed in the high-flow low-temperature water outlet mode, so that a pressurized air chamber for improving the water outlet flow is formed at the upper part of the shell 100, the water outlet speed of the water outlet 120 is increased along with the increase of the pressure of the pressurized air chamber, and the air outlet 130 is closed in the high-flow low-temperature water outlet mode, so that the problem that water in the shell 100 overflows from the air outlet 130 is avoided, and the water outlet efficiency is improved. The requirements of small-flow water outlet of high-temperature boiling water and large-flow water outlet of normal-temperature water outlet are met, and the water outlet efficiency can be improved.
It can be understood that in the low-flow high-temperature water outlet mode, the water dispenser needs to provide boiling water, the heating power of the heating module is limited, water needs to be fed at a small flow rate to ensure continuous boiling water outlet, and high-temperature steam is mixed in the boiling water, for example, water with the temperature of 90 ℃ or higher, so that the high-temperature steam needs to be discharged in the low-flow high-temperature water outlet mode.
Under the large-flow low-temperature water outlet mode, the water dispenser needs to discharge water in a large flow rate, so that water entering the shell of the water-steam separation device needs to enter water in a large flow rate mode, but in order to avoid the problem that water is not full when a user receives water, the shell is usually small in size, the water level in the shell is enabled to rise rapidly, and the problem of overflow from an exhaust port is easy to occur.
In some embodiments, the water outlet rate is adjusted by designing the aperture of the water outlet 120, the aperture of the water outlet is such that, when the water inlet flow rate is L ml/s in the open state of the exhaust port switch assembly, the lowest water outlet rate from the water outlet is L ml/s under the action of the self weight of the water in the housing, so as to ensure that the liquid level in the housing does not increase with the passage of time when the exhaust port switch assembly is opened, thereby avoiding the problem of exhaust port overflow in the open state of the exhaust port switch assembly. Because the heating power of the heating module is limited, in order to ensure continuous boiling water outlet, the water inlet flow needs to be reduced, therefore, the water flow of the high-temperature water is usually smaller, generally 4ml/s to 10ml/s, the volume of the shell can be correspondingly designed to be smaller, and the phenomenon that the water is not exhausted due to more water in the shell after the user clicks to stop water outlet is avoided.
And, under the condition that the bore of the water outlet 120 meets the condition, the water flow form can be better ensured by reducing the bore of the water outlet 120, and the condition of water column deviation is avoided, so that a water nozzle device is not required to be added on the water dispenser, and the cost of the water dispenser is saved.
In some embodiments, the outlet opening/closing assembly includes an opening/closing valve 201 disposed at the outlet opening 130, the opening/closing valve 201 is configured to open the outlet opening 130 in the low flow rate high temperature water outlet mode to discharge the high temperature steam separated from the high temperature water, and the opening/closing valve 201 is further configured to close the outlet opening 130 in the high flow rate low temperature water outlet mode to form a pressurized air chamber at the upper portion of the housing to increase the flow rate of the outlet water. In the low-flow high-temperature water outlet mode, the air outlet 130 is opened by using the switch valve 201, and because the water inlet flow is small at the moment, the water level in the shell 100 rises slowly, the situation that water in the shell 100 overflows from the air outlet 130 cannot occur, and high-temperature steam mixed in high-temperature water can be discharged from the air outlet 130 to avoid burning; under the high-flow low-temperature water outlet mode, the air outlet 130 is closed by the switch valve 201, the water inlet speed of the water inlet 110 is higher than the water outlet speed of the water outlet 120, the pressure in the shell 100 is increased along with the increase of water in the shell 100, the water outlet speed of the water outlet 120 is increased, so that water can be discharged quickly, the situation that water in the shell 100 overflows from the air outlet 130 can be avoided when the air outlet 130 is closed, when the water level in the shell 100 begins to fall, the pressure in the shell 100 is gradually reduced, the floating piece 200 falls onto the water surface or the bottom of the shell 100 from the air outlet 130 under the action of the atmospheric pressure outside the shell 100, and the opening and closing state of the air outlet 130 can be automatically adjusted without the action of external force.
In some embodiments, the switch valve 201 is an electric valve, for example, in one embodiment, the switch valve 201 is a solenoid valve, which has high control precision and flexibility, so that the process of discharging steam is more sensitive.
In one embodiment, the switch valve 201 is disposed at the middle section of the housing 100 in the transverse direction, so as to uniformly discharge the high-temperature steam at various positions in the housing 100, thereby greatly reducing the possibility of burning caused by the liquid water discharged from the water outlet 120 without discharging the high-temperature steam.
Referring to fig. 2 to 4, in some embodiments, the exhaust port switch assembly includes a float member 200, the float member 200 being provided within the housing to rise and close the exhaust port as the water level within the housing rises. Under the low-flow high-temperature water outlet mode, because the water inlet flow is small, the water level in the shell 100 rises slowly, the situation that water in the shell 100 overflows from the air outlet 130 cannot occur, and meanwhile, the floating piece 200 cannot rise to the position for blocking the air outlet 130, so that high-temperature steam mixed in high-temperature water is discharged from the air outlet 130, and burns are avoided; under the high-flow low-temperature water outlet mode, the water inlet speed of the water inlet 110 is greater than the water outlet speed of the water outlet 120, the floating piece 200 rises and blocks the air outlet 130, the pressure in the shell 100 is increased, the water outlet speed of the water outlet 120 is increased, water can be discharged quickly, the situation that water in the shell 100 overflows from the air outlet 130 is avoided, when the water level in the shell 100 begins to fall, the pressure in the shell 100 is gradually reduced, the floating piece 200 falls onto the water surface or the bottom of the shell 100 from the air outlet 130 under the action of the atmospheric pressure outside the shell 100, and the opening and closing state of the air outlet 130 can be automatically adjusted without the action of external force.
It can be understood that, in actual use, the water demand at normal temperature may also include a small flow water demand of the water at normal temperature and a large flow water demand of the water at normal temperature. Under the requirement of low-flow water outlet of normal-temperature water, the water level in the shell 100 rises slowly, and the water in the shell 100 cannot overflow from the air outlet 130; referring to fig. 3, in the demand of large flow of water out of the normal temperature water, when the water inlet speed of the water inlet 110 is greater than the water outlet speed of the water outlet 120, the floating member 200 rises and blocks the air outlet 130, so that the pressure inside the housing 100 increases, and the water outlet speed of the water outlet 120 increases, thereby discharging water quickly, and avoiding the situation that water inside the housing 100 overflows from the air outlet 130, when the water level inside the housing 100 begins to drop, the pressure inside the housing 100 decreases gradually, and the floating member 200 drops from the air outlet 130 to the water surface or the bottom of the housing 100 under the action of the atmospheric pressure outside the housing 100 without the action of external force.
In fig. 3, the wavy line inside the casing 100 and at the air outlet 130 indicates the water vapor inside the casing 100, and the short line inside the casing 100 indicates the water inside the casing 100.
In some embodiments, the exhaust port opening and closing assembly further includes a guide 300, the guide 300 for guiding a rising direction of the float 200, a guide path of the guide 300 being directed toward the exhaust port 130. When the water level in the shell 100 rises, the floating piece 200 rises along with the rise of the water level under the buoyancy action of water, in the rising process of the floating piece 200, the guide piece 300 guides the rising path of the floating piece 200, so that the floating piece 200 is prevented from deviating from the position of the air outlet 130 in the rising process, the air outlet 130 is plugged by the floating piece 200 more quickly and accurately, after the air outlet 130 is plugged, the water quantity in the shell 100 is continuously increased, the pressure in the shell 100 is increased, the water outlet speed of the water outlet 120 is increased, and water cannot overflow from the air outlet 130 on the premise of realizing large-flow water outlet.
In some embodiments, the air outlet 130 is disposed at the top of the housing 100, so that the water vapor can be rapidly and smoothly discharged from the air outlet 130 during the natural rising process, thereby improving the water-vapor separation efficiency, reducing the probability of the water vapor coming out of the water outlet 120 together with the high-temperature boiling water, and further reducing the probability of the user's burn; the guide path of the guide member 300 is along the up-down direction, so that the floating member 200 can be more rapidly and smoothly lifted to the air outlet 130 in the process of lifting along with the rising of the water level, and the air outlet 130 is more accurately sealed, so that the water outlet speed of the water outlet 120 is more rapidly increased, and the effect of discharging water at a large flow rate is further rapidly achieved. It is understood that the guide path of the guide 300 in the up-down direction includes a case where the guide path is slightly inclined in the vertical direction and the guide path.
In an embodiment, the guiding member 300 is a sleeve, an upper end of the sleeve is connected to the housing 100 and is disposed around the air outlet 130, a lower end of the sleeve is disposed at an interval between bottoms of the housing 100, and an upper end of the floating member 200 is slidably received in the sleeve, that is, the upper end of the floating member 200 is limited by the sleeve, so that the floating member 200 does not deviate from the position of the air outlet 130 and does not topple over on the water surface, and the air outlet 130 can be blocked by the floating member 200 more smoothly.
In another embodiment, the guiding member 300 is a sleeve, the upper end of the sleeve is connected to the casing 100 and is disposed around the exhaust port 130, the lower end of the sleeve is disposed at intervals between the bottom of the casing 100, the upper end and the middle portion of the floating member 200 are slidably received in the sleeve, and the sleeve is uniformly provided with air holes at intervals. Because the upper end and the middle part of the floating piece 200 are both accommodated in the sleeve, in the process of water level rising, the overlapped part of the floating piece 200 between the sleeves in the up-down direction is more, so that the floating piece 200 can be kept in a stable state on the water surface better, the rising path of the floating piece 200 is closer to the vertical direction, and the floating piece 200 can better block the air outlet 130; moreover, since the sleeve is provided with the air holes at uniform intervals, the water vapor in the casing 100 can enter the air outlet 130 from the bottom of the sleeve and the air holes uniformly distributed at intervals on the sleeve, so that the water vapor at different positions in the casing 100 can be quickly and uniformly discharged from the air outlet 130.
In one embodiment, the guiding member 300 is a sleeve, the lower end of the sleeve is connected to the bottom of the housing, the upper end of the sleeve extends to the periphery of the exhaust port, the floating member 200 is slidably disposed in the sleeve, and the lower end of the sleeve is provided with a flow passage communicating the housing with the sleeve. The lower end of the sleeve is connected with the shell 100, so that the sleeve limits the position of the lower end of the floating piece 200, the lower end of the floating piece 200 is kept stable, and the floating piece 200 is not easy to topple or turn over on the water surface so as to better block the air outlet 130; meanwhile, the lower end of the sleeve is provided with the circulation channel, so that after water enters the shell 100 from the water inlet 110, the water can not only bypass the sleeve and flow out from the water outlet 120, but also can enter the sleeve through the circulation channel on the wall of the sleeve on one side of the sleeve, and flow into the shell 100 through the circulation channel on the wall of the sleeve on the other side of the sleeve, so that the water is close to the water outlet 120 and flows out from the water outlet 120, and after the water enters the water inlet 110, the water outlet 120 can more quickly flow out. In other embodiments, a plurality of flow passages may be spaced apart in the sleeve to allow water in the housing 100 to more uniformly and rapidly flow through the sleeve.
In an embodiment, the flow channel is a plurality of through holes disposed on the sleeve, and the plurality of through holes are distributed on the wall of the sleeve at intervals along the circumferential direction of the wall, so that water in the housing 100 can more rapidly and uniformly pass through the sleeve, thereby making the flow of water in the housing 100 smoother, and further making the water outlet of the water outlet 120 smoother.
In some embodiments, the guide 300 is a guide rail extending in the up-down direction, the floating member 200 is slidably disposed on the guide rail, and the guide rail is used to limit and guide the movement path of the floating member 200, so that the structure is simple, the occupied space in the housing 100 is small, and at the same time, the smooth circulation of water in the housing 100 can be ensured.

In one embodiment, the number of the guide rails is two, the two guide rails are respectively arranged on two sides of the floating member 200, and the guide rails on the two sides are used for simultaneously guiding the floating member 200, so that the movement of the floating member 200 is more stable, and the floating member 200 can more accurately block the air outlet 130. In other embodiments, the number of guide rails may be adaptively adjusted according to practical application scenarios such as space in the housing, shape of the floating member, and the like.
In some embodiments, the guide rails are cylindrical straight bars or flat straight bars, the number of the guide rails is three, three guide rails are arranged around the circumference of the floating member 200, and the three guide rails form a floating channel for the floating member 200 to float, so that the moving path of the floating member 200 is limited and guided. In addition, the position of the side wall of the floating member 200 corresponding to the guide rail may be correspondingly provided with a limit groove matched with the guide rail, so that the movement of the floating member 200 is more stable, and the floating member 200 can be more accurately lifted to the air outlet 130 and can block the air outlet 130.
In other embodiments, the specific number of the guide rails is not limited, and may be four, five, six or more, and the space between the guide rails is enough that the floating member 200 cannot be removed from between two adjacent guide rails.
In some embodiments, the floating member 200 has a floating body and an insertion portion 210 disposed at an upper end of the floating body, and a shape and a size of the insertion portion 210 are matched with a shape and a size of the air outlet 130, so that the insertion portion 210 blocks the air outlet 130 after the floating member 200 rises with a water level, and since the shape and the size of the insertion portion 210 are matched with a shape and a size of the air outlet 130, when the insertion portion 210 is inserted into the air outlet 130, a sealing effect at the air outlet 130 is better, so that a pressure inside the housing 100 is increased more quickly, the increase degree is higher, and a water outlet speed of the water outlet 120 is higher.

In other embodiments, the number of the arc-shaped plates may be provided as three, four, five, or more, and a plurality of arc-shaped plates are uniformly spaced around the float 200, thereby reducing the obstruction of the water flow in the housing 100 by the guide 300, so that the water flow of the housing 100 is smoother.
In an embodiment, the casing 100 is convexly provided with the sealing ring 400 at the periphery of the exhaust port 130, and the sealing ring 400 is arranged in the casing 100, when the floating member 200 blocks the exhaust port 130, the embedding portion 210 is embedded in the sealing ring 400, and the arrangement of the sealing ring 400 increases the contact area between the embedding portion 210 and the casing 100 when the embedding portion 210 is embedded, so that the friction force between the embedding portion 210 and the casing is increased, the floating member 200 is not easy to slide down, and the sealing effect is better; furthermore, the sealing ring 400 is disposed in the housing 100, so that when the floating member 200 blocks the air outlet 130, the embedded portion 210 is hidden in the sealing ring 400, that is, the embedded portion 210 can be completely or partially hidden in the housing 100, thereby reducing the space occupation of the water dispenser.

In some embodiments, a gap is provided between the sleeve and the floating member 200, so that during the process of the floating member 200 rising in the sleeve, the floating member 200 does not contact with the sleeve, thereby avoiding the sleeve from generating friction force on the floating member 200, making the rising process of the floating member 200 smoother, and simultaneously avoiding the floating member 200 from being worn, so that the floating member 200 and the exhaust port 130 can be well sealed.
In an embodiment, the difference between the diameter of the sleeve and the diameter of the floating member 200 is 1mm, so that the sleeve guides the ascending path of the floating member 200, which not only achieves the purpose of non-contact between the sleeve and the floating member 200, but also prevents the floating member 200 from continuously inclining in time when the floating member 200 inclines due to water surface fluctuation, so that the ascending path of the floating member 200 is corrected to a preset path, and the floating member 200 blocks the exhaust port 130 more smoothly. In other embodiments, the difference between the diameter of the sleeve and the diameter of the float member 200 may be adaptively adjusted, such as 0.5mm, 1.5mm, 2 mm.
