The invention provides a water-vapor separation device which is applied to a water dispenser, wherein the water dispenser is provided with 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 a floating member 200, wherein a water inlet 110 and a water outlet 120 are provided at the lower part of the housing 100, an air outlet 130 is provided at the upper part of the housing 100, the water inlet 110 is connected to a water outlet pipe of a water tank of a water dispenser, the water outlet pipe is used for outputting high-temperature water in a low-flow high-temperature water outlet mode, outputting normal-temperature water or low-temperature water in a high-flow low-temperature water outlet mode, the water outlet 120 is used for discharging water, and the air outlet 130 is used for discharging water vapor; the floating member 200 is disposed in the housing 100, and is used to block the air outlet 130 along with the rising of the water level in the high-flow low-temperature water outlet mode, so as to form a pressurizing air cavity at the upper part of the housing 100 for increasing the water outlet flow; the float member 200 also serves to open the exhaust port 130 as the water level decreases in a low flow high temperature water discharge mode to discharge high temperature steam separated from the high temperature water.

In the low-flow high-temperature water outlet mode, the water level in the shell 100 rises slowly due to the small water inlet flow, the situation that water in the shell 100 overflows from the air outlet 130 is avoided, meanwhile, the floating piece 200 cannot rise to the position for blocking the air outlet 130, at the moment, the air outlet 130 is opened, high-temperature steam mixed in high-temperature water is discharged from the air outlet 130, and meanwhile, the water outlet 120 outputs high-temperature boiling water, namely, the water outlet 120 outputs high-temperature boiling water, so that burns caused by water vapor and water column of the high-temperature boiling water driven to drift by the water vapor are avoided.

In the high-flow low-temperature water outlet mode, when the water inlet speed of the water inlet 110 is greater than the water outlet speed of the water outlet 120, the water level in the shell 100 rises, the floating piece 200 rises and seals the air outlet 130, so that the air pressure at the upper part of the shell 100 increases, the water level also continues to rise, the water flow speed of the water outlet 120 increases, namely water is discharged quickly, and the situation that water in the shell 100 overflows from the air outlet 130 is avoided; when the water receiving of the user is finished and the water level in the casing 100 begins to drop, the pressure in the casing 100 gradually decreases, the floating member 200 falls onto the water surface from the air outlet 130 under the action of the atmospheric pressure outside the casing 100 or the bottom of the casing 100, the opening and closing state of the air outlet 130 can be automatically adjusted without the action of external force, the automatic opening and closing of the air outlet 130 is realized, other structures are not required to be added, the structure is simplified, and materials are saved.

It will be appreciated that in actual use, if the water demand of the user is low-flow low-temperature water, the water level in the housing 100 will rise slowly, and the water in the housing 100 will not overflow from the air outlet 130.

According to the technical scheme, the water inlet 110 and the water outlet 120 are arranged at the lower part of the shell, the air outlet 130 is arranged at the upper part of the shell, the air outlet 130 is plugged by utilizing the floating piece 200 in a high-flow low-temperature water outlet mode along with the rising of the water level, so that a pressurizing air cavity 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 increasing of the pressure intensity of the pressurizing air cavity, the problem that water in the shell overflows from the air outlet 130 is avoided, and meanwhile, the water outlet efficiency is improved; the air outlet 130 is opened along with the water level reduction in a low-flow high-temperature water outlet mode by utilizing the floating piece 200, and the high-temperature steam separated from the high-temperature water is prevented from being burnt due to the fact that the high-temperature boiling water column is driven by the steam and the steam; 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 will be appreciated that in the low-flow high-temperature water outlet mode, the water dispenser needs to provide boiling water, and the heating power of the heating module is limited, so that water is usually required to be fed in a low-flow manner to ensure continuous water outlet, and high-temperature steam is usually mixed in the boiling water, for example, water with the temperature of more than 90 ℃, so that the high-temperature steam needs to be discharged in the low-flow high-temperature water outlet mode.

And under the low temperature mode of leaving water of large-traffic, the water dispenser needs to leave water with the large-traffic, this just makes the water that gets into in the casing of water vapor separator also advance water with the large-traffic mode, but in order to avoid the user to connect the problem that water is not full when water, generally set up the casing volume less for the water level in the casing risees fast, appears easily from the problem that the gas vent overflows, this application is through closing gas vent 130 under the low temperature mode of leaving water of large-traffic, not only solved the problem that water overflows, can also increase the play water velocity of delivery port 120.

In some embodiments, the water outlet rate is further adjusted by designing the caliber of the water outlet 120, the caliber of the water outlet should meet, when the water inlet flow is L ml/s in the open state of the air outlet 130, the lowest water outlet rate of the water outlet is L ml/s under the action of self weight of the water in the shell, so as to ensure that the liquid level in the shell will not increase with time when the air outlet 130 is opened, thereby avoiding the problem of overflow of the air outlet in the open state of the air outlet 130. Because the heating power of the heating module is limited, the water inflow needs to be reduced in order to ensure continuous water outflow, the water inflow of high-temperature water is usually smaller, generally 4ml/s to 10ml/s, the volume of the shell can be correspondingly designed smaller, and the phenomenon that more water in the shell causes 'water inexhaustible' after a user clicks to stop water outflow is avoided.

In addition, when the caliber of the water outlet 120 meets the condition, the caliber of the water outlet 120 is reduced, so that the water flow form can be better ensured, the condition of water column deviation is avoided, a water nozzle device is not required to be added on the water dispenser, and the cost of the water dispenser is saved.

The wavy line at the air outlet 130 and the inside of the housing 100 shown in fig. 2 is an indication of water vapor in the housing 100, and the short line segment inside the housing 100 is an indication of water in the housing 100.

Referring to fig. 3, in some embodiments, a guide 300 is provided in the housing 100, the guide 300 for guiding the rising direction of the float 200, and a guide path of the guide 300 is directed toward the exhaust port 130. When the water level in the housing 100 rises, the floating member 200 rises along with the rise of the water level under the buoyancy of the water, and the guide member 300 guides the rising path of the floating member 200 in the rising process of the floating member 200, so that the floating member 200 is prevented from deviating from the position of the air outlet 130 in the rising process, the air outlet 130 is blocked more rapidly and accurately, after the air outlet 130 is blocked, the water quantity in the housing 100 is continuously increased, so that the pressure in the housing 100 is increased, the water outlet speed of the water outlet 120 is increased, and the 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 quickly and smoothly discharged from the air outlet 130 in the natural rising process, thereby improving the efficiency of water-gas separation, reducing the probability of water vapor and high-temperature boiling water coming out of the water outlet 120 together, and further reducing the probability of burn of users; the guide path of the guide 300 is along the up-down direction, so that the floating member 200 can rise to the air outlet 130 more rapidly and smoothly in the rising process along with the rising of the water level, thereby more accurately blocking the air outlet 130, enabling the water outlet speed of the water outlet 120 to increase more rapidly, and further achieving the effect of large-flow water outlet more rapidly. It is understood that the guide path of the guide 300 includes a case where the guide path is slightly inclined in the vertical direction and the guide path in the up-down direction.

In an embodiment, the guide 300 is a sleeve, the upper end of the sleeve is connected to the housing 100 and is disposed around the air outlet 130, the lower end of the sleeve is disposed at intervals between the bottom of the housing 100, and the upper end of the floating member 200 is slidingly received in the sleeve, i.e. 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 fall over on the water surface, thereby enabling the floating member 200 to more smoothly block the air outlet 130.

In another embodiment, the guide 300 is a sleeve, the upper end of the sleeve is connected to the housing 100 and is disposed around the exhaust port 130, the lower end of the sleeve is disposed between the bottom of the housing 100, the upper end and the middle of the floating member 200 are slidingly received in the sleeve, and ventilation holes are uniformly disposed on the sleeve 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 raising the water level, the overlapped parts of the floating piece 200 between the sleeves in the up-down direction are more, so that the floating piece 200 can better keep a stable state on the water surface, the ascending path of the floating piece 200 is more similar to the vertical upward direction, and the floating piece 200 can better block the air outlet 130; in addition, since the ventilation holes are uniformly arranged on the sleeve at intervals, the water vapor in the shell 100 can enter the exhaust port 130 from the bottom of the sleeve and the ventilation holes uniformly distributed on the sleeve at intervals, so that the water vapor in different positions in the shell 100 can be rapidly and uniformly discharged from the exhaust port 130.

In one embodiment, the guiding element 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 element 200 is slidably disposed in the sleeve, and the lower end of the sleeve is provided with a flow channel communicating with the housing and the sleeve. Because the lower end of the sleeve is connected with the shell 100, the sleeve limits the position of the lower end of the floating piece 200, so that the lower end of the floating piece 200 is kept stable, and the floating piece 200 is not easy to topple over or overturn on the water surface, so that the exhaust port 130 is better blocked; meanwhile, as the lower end of the sleeve is provided with the circulation channel, 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 enter the sleeve through the circulation channel on the wall of one side of the sleeve, and flow into the shell 100 to be close to the water outlet 120 and flow out from the water outlet 120 through the circulation channel on the wall of the other side of the sleeve, so that after the water enters the water inlet 110, the water outlet 120 can discharge water more rapidly. In other embodiments, a plurality of flow channels may be provided on the sleeve at intervals to allow water within the housing 100 to flow more evenly and quickly through the water within the sleeve.

In an embodiment, the circulation 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 of the sleeve, so that water in the housing 100 can pass through the sleeve more rapidly and uniformly, thereby enabling the circulation of water in the housing 100 to be smoother, and further enabling the water outlet of the water outlet 120 to be smoother.

In some embodiments, the guide 300 is a guide rail extending along 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 space occupation in the housing 100 is small, and meanwhile, the smooth circulation of the water in the housing 100 can be ensured.

In the above embodiment, the guide rail may be selected from a T-shaped guide rail or a dovetail-shaped guide rail, and the floating member 200 is correspondingly provided with an assembly groove matched with the guide rail, so that the floating member 200 slides smoothly along the guide rail without derailing by using the cooperation between the assembly groove and the guide rail. In one embodiment, the number of the guide rails is two, and the two guide rails are respectively arranged at two sides of the floating member 200, and the floating member 200 is guided by the guide rails at two sides at the same time, so that the movement of the floating member 200 is smoother, and the floating member 200 can more accurately block the exhaust port 130. In other embodiments, the number of the guide rails may be adaptively adjusted according to the space in the housing, the 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 guide rails is three, three guide rails are disposed around the circumference of the float member 200, and the three guide rails form a float channel for the float member 200 to float, thereby limiting and guiding the movement path of the float member 200. In addition, the side walls of the floating member 200 may be provided with corresponding limit grooves corresponding to the guide rails, so that the movement of the floating member 200 is smoother, thereby allowing the floating member 200 to more accurately rise to the air outlet 130 and blocking the air outlet 130.

In other embodiments, the specific number of rails is not limited, and four, five, six, or more rails may be provided, with a spacing between the rails such that the float 200 cannot be removed from between two adjacent rails.

In some embodiments, the floating member 200 has a floating body and an insert portion 210 disposed at an upper end of the floating body, and the insert portion 210 has a shape and size matching those of the vent 130, so that the insert portion 210 seals the vent 130 after the floating member 200 rises with the water level, and the insert portion 210 has a shape and size matching those of the vent 130, so that when the insert portion 210 is inserted into the vent 130, the seal effect at the vent 130 is better, thereby increasing the pressure in the housing 100 more rapidly, and increasing the water outlet speed of the water outlet 120 more rapidly.

Referring to fig. 4 and 5, in an embodiment, the floating body of the floating member 200 is in a column shape, the embedded portion 210 is protruded at the upper end of the floating body, when the embedded portion 210 is embedded into the air outlet 130, the upper surface of the floating body abuts against the inner wall of the housing 100, and on one hand, the gap between the floating member 200 and the air outlet 130 is blocked, so that the sealing effect is better, and at the same time, when the water level in the housing 100 is lowered, the floating member 200 can more smoothly drop onto the water surface from the air outlet 130 or the bottom of the housing 100; on the other hand, the float 200 is prevented from being washed out of the housing 100 by water in the housing 100.

In an embodiment, the floating body of the floating member 200 is in a column shape, the guide member 300 includes a sleeve disposed at the air outlet 130 and an arc plate disposed at the bottom of the housing 100 (refer to fig. 2 and 3), wherein the curvature of the arc plate is the same as that of the floating member 200, and two arc plates are provided, and an accommodating space for accommodating the floating member 200 is formed between the two arc plates, so that the cross section of the accommodating space and the cross section of the floating member 200 form a concentric circle structure, thereby not only realizing the limiting and guiding of the floating member 200, but also reducing the space occupied by the guide member 300 in the housing 100 to a greater extent. In other embodiments, the number of arcuate plates may be set to three, four, five or more, with a plurality of arcuate plates being evenly spaced around the float 200 to reduce obstruction of the water flow within the housing 100 by the guide 300, resulting in a smoother water flow of the housing 100.

In an embodiment, the casing 100 is convexly provided with the sealing ring 400 at the periphery of the air outlet 130, and the sealing ring 400 is arranged in the casing 100, when the floating piece 200 seals the air outlet 130, the embedded part 210 is embedded in the sealing ring 400, and the arrangement of the sealing ring 400 increases the contact area between the embedded part 210 and the casing 100 when the embedded part 210 is embedded, so that the friction force between the embedded part 210 and the casing is increased, and the floating piece 200 is not easy to slide downwards, so that the sealing effect is better; in addition, the seal ring 400 is disposed in the housing 100, so that when the floating member 200 seals the air outlet 130, the embedded portion 210 is hidden in the seal ring 400, that is, the embedded portion 210 can be completely or partially hidden in the housing 100, thereby reducing the occupation of the space of the water dispenser.

In an embodiment, a rounded corner is disposed at one end of the seal ring 400 facing the inside of the housing, so that the seal ring 400 forms an embedding channel at the vent 130 for the embedding portion 210 to embed, the embedding channel tapers from the inside of the housing to the direction of the vent, so that the embedding portion 210 is convenient to embed, and the shape of the embedding portion 210 matches with the shape of the embedding channel, so that the sealing effect is better.

In the above embodiment, the float member 200 is a float made of food-grade heat resistant material, and the float is provided in a hollow structure so that the float can rise more sensitively and rapidly as the water level rises. In an embodiment, the floating body is hollow, and the embedded portion 210 is of a solid structure, so that the embedded portion 210 is not easy to deform due to pressure when the floating member 200 is inserted into the air outlet 130 on the premise of floating on the water surface, so as to better ensure the sealing effect.

In some embodiments, a gap is provided between the sleeve and the float member 200, so that the float member 200 is not in contact with the sleeve during the process of lifting the float member 200 in the sleeve, thereby avoiding friction force generated by the sleeve on the float member 200, so that the lifting process of the float member 200 is smoother, and meanwhile, the float member 200 is prevented from being worn, so that a good seal is kept before the float member 200 and the exhaust port 130.

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, not only achieves the purpose of no contact between the sleeve and the floating member 200, but also can prevent the floating member 200 from continuing to incline in time when the floating member 200 inclines due to water surface fluctuation, thereby correcting the ascending path of the floating member 200 to a preset path, and further enabling the floating member 200 to more smoothly block the air outlet 130. In other embodiments, the difference between the diameter of the sleeve and the diameter of the float member 200 may be adapted, such as 0.5mm, 1.5mm, 2mm.

In this embodiment, in the low-flow high-temperature water outlet mode, that is, the heat pipe 32 heats the passing water, the heated high-temperature boiling water enters the water-vapor separation device to perform water-vapor separation, and then is output from the water outlet for a user to take, and by separating the high-temperature boiling water from the water vapor, burn caused by the water vapor and the water column of the high-temperature boiling water driven to drift by the water vapor is avoided; in the high flow low temperature water outlet mode, i.e. the heat pipe 32 does not heat the passing water, or the heating temperature is low, so that the water outlet outputs low temperature water.

In an embodiment, the water-vapor separation device is arranged in the water tank 01, the water tank 01 is provided with an atmosphere communication port 11 communicated with the atmosphere, a part of high-temperature steam separated in the low-flow high-temperature water outlet mode is absorbed by water in the water tank 01, and the rest is discharged into the atmosphere from the atmosphere communication port 11, so that the water-vapor separation device can occupy additional space in the water dispenser, and the steam amount integrally discharged in the low-flow high-temperature water outlet mode can be reduced. In another embodiment, the water-vapor separation device is arranged outside the water tank 01, and an exhaust pipe communicated with the atmosphere is connected to an exhaust port of the water-vapor separation device.

In some embodiments, the water dispenser further includes a mode controller electrically connected to both the water pump 31 and the heating module to control the heating module to be turned on and to control the water pump to output a small flow in a low-flow high-temperature water outlet mode, and to control the water pump to output a large flow in a high-flow low-temperature water outlet mode, and/or to control the heating module to be turned off or to reduce power.

Specifically, in the low-flow high-temperature water outlet mode, the mode controller controls the heating module to be started, and in order to ensure continuous water outlet, the water suction pump needs to be controlled to output low flow. In the high-flow low-temperature water outlet mode, according to the actual water temperature requirement of a user, the mode controller controls the water pump to change the water outlet flow or controls the heating module to be closed, or simultaneously controls the water pump to change the water outlet flow and controls the heating module to be closed, for example, in the high-flow low-temperature water outlet mode, when the mode controller controls the water pump to output the high flow, the heating state of the heating module is kept unchanged, at the moment, the water outlet temperature of the water outlet is reduced due to the increase of the speed of the incoming cold water, if the water outlet temperature of the water outlet can be reduced to the required temperature of the user only by increasing the flow, the heating module is not required to be controlled to change the heating state, and if the output flow of the water pump reaches the maximum flow, the water outlet temperature of the water outlet cannot be reduced to the required temperature of the user, and the heating module is required to be closed at the same time. The control process can be controlled by adopting a PID algorithm, and the power of the heating module and the voltage of the water suction pump are adjusted by starting the PID algorithm.
