Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gas-liquid separation, in particular to a gas-liquid separator and a household appliance with the same. BACKGROUND

[0002] The gas-liquid separator mainly comprises a cyclone vane, a water baffle, a liquid separation chamber, a drain pipe and the like. The gas flow containing liquid impurities flows into the liquid separation chamber through the inlet. The gas flow generates a peripheral velocity under the action of the cyclone vane. The liquid impurities are entrained by the rotating gas flow and move to the inner wall of the liquid separation chamber. Thus, the liquid impurities are gathered into a liquid film on the inner wall surface of the liquid separation chamber under the action of centrifugal force. The liquid film flows along the inner wall surface of the liquid separation chamber under the action of the shear force of the gas flow, and is guided to the drain pipe by the water baffle and then flows out, so as to separate and remove the liquid impurities in the gas flow to obtain dry gas.

[0003] However, the water baffle of the existing gas-liquid separator is fixedly arranged on the shell. The fixedly arranged water baffle can only meet the gas-liquid separation effect and efficiency of a certain humidity gas flow. However, when the gas-liquid separation operation is performed on a gas flow with high humidity, the separation effect is poor, and even multiple gas-liquid separation operations are required, resulting in low separation efficiency. When the gas-liquid separation operation is performed on a gas flow with low humidity, the gas-liquid separation effect is ensured, but the gas-liquid separation efficiency cannot be improved. SUMMARY

[0004] The first object of the present application is to provide a gas-liquid separator with an adjustable water baffle. The water baffle can be adaptively adjusted according to different humidity gas flows, so as to improve the gas-liquid separation effect and efficiency.

[0005] The second object of the present application is to provide a household appliance with the above-mentioned gas-liquid separator.

[0006] In order to achieve the first object of the present application, the present application provides a gas-liquid separator, comprising a shell and a cyclone vane, the shell is provided with a separation cavity, an upper end of the separation cavity is provided with an air inlet, the cyclone vane is arranged in the separation cavity to force the airflow entering the separation cavity from the air inlet to rotate, the gas-liquid separator further comprises a rotating plate, an adjusting control mechanism and a plurality of water baffle plates, a lower end plate of the separation cavity is provided with an air outlet, a circumferential wall of the shell is provided with a liquid outlet in communication with the separation cavity, the liquid outlet is arranged close to the lower end plate, the rotating plate is arranged in the separation cavity and below the cyclone vane in the vertical direction, and the rotating plate is provided with a through hole, the plurality of water baffle plates are arranged in the separation cavity and below the rotating plate in the vertical direction, the plurality of water baffle plates are distributed equidistantly in the circumferential direction of the separation cavity, and the inner circumferential ends of the plurality of water baffle plates are arranged to protrude inside the through hole and the air outlet in the horizontal direction and enclose an air outlet hole, each water baffle plate is rotatably hinged to the lower end plate, and each water baffle plate is arranged to protrude a limiting column, the rotating plate is provided with a plurality of arc-shaped grooves, one arc-shaped groove is sleeved on one limiting column, and the adjusting control mechanism can control the rotating plate to rotate around the vertical direction, so that one arc-shaped groove forces one limiting column to move in the radial direction and the circumferential direction of the air outlet hole to adjust the size of the air outlet hole.

[0007] As can be seen from the above scheme, when the gas-liquid separator of the present application performs gas-liquid separation operation, the airflow containing liquid impurities enters the inside of the separation cavity of the shell from the air inlet of the separation cavity of the shell, and the cyclone vane arranged in the separation cavity forces the airflow containing liquid impurities entering the separation cavity from the air inlet to rotate, so that the airflow containing liquid impurities generates a circumferential velocity under the action of the cyclone vane, and the liquid impurities move to the inner wall of the separation cavity under the entrainment of the rotating airflow, thereby forming a liquid film on the inner wall surface of the separation cavity under the action of the centrifugal force, the liquid film flows along the inner wall surface of the separation cavity under the action of the shear force of the airflow, and the liquid film on the inner wall surface of the separation cavity flows along the inner wall surface of the separation cavity under the action of gravity and flows to the water baffle plate, and the water baffle plate guides the liquid film to the liquid outlet on the circumferential wall of the shell for discharge, and the dry gas after separating the liquid impurities is discharged through the air outlet hole surrounded by the inner circumferential ends of the plurality of water baffle plates, so that the dry gas is obtained.

[0008] The adjusting and controlling mechanism of the gas-liquid separator can control the rotation of the rotating plate around the vertical direction, so that an arc-shaped slot on the rotating plate forces a limiting column on a water baffle to move in the radial direction and the circumferential direction of the exhaust hole, so as to adjust the size of the exhaust hole surrounded by the inner circumferential ends of the plurality of water baffles. Therefore, when it is detected that the dry gas discharged from the exhaust hole surrounded by the inner circumferential ends of the plurality of water baffles has a relatively large humidity, the adjusting and controlling mechanism of the gas-liquid separator controls the rotating plate to rotate forward around the vertical direction, so that an arc-shaped slot on the rotating plate forces a limiting column on a water baffle to move in the radial direction and the circumferential direction of the exhaust hole, so as to reduce the aperture of the exhaust hole surrounded by the inner circumferential ends of the plurality of water baffles, so that the gas-liquid separator can separate and remove more liquid impurities from the gas flow containing liquid impurities, reduce the humidity of the gas, and obtain dry gas, thereby improving the gas-liquid separation effect of the gas flow with relatively large humidity and improving the gas-liquid separation efficiency. When it is detected that the dry gas discharged from the exhaust hole surrounded by the inner circumferential ends of the plurality of water baffles has a relatively small humidity, the adjusting and controlling mechanism of the gas-liquid separator controls the rotating plate to rotate reversely around the vertical direction, so that an arc-shaped slot on the rotating plate forces a limiting column on a water baffle to move in the radial direction and the circumferential direction of the exhaust hole, so as to increase the aperture of the exhaust hole surrounded by the inner circumferential ends of the plurality of water baffles, thereby improving the gas-liquid separation effect of the gas flow with relatively small humidity and greatly improving the gas-liquid separation efficiency.

[0009] Therefore, the gas-liquid separator provided by the present application is provided with adjustable water baffles, which can be adaptively adjusted according to different humidity gas flows, so as to improve the gas-liquid separation effect and improve the gas-liquid separation efficiency.

[0013] A further scheme is that each water baffle is provided with a hinge hole, the inner end surface of the lower end plate is provided with a plurality of rotating shafts, and one hinge hole is rotatably sleeved on one rotating shaft.

[0014] A further scheme is that one hinge hole is located at one end of one water baffle in the circumferential direction of the exhaust hole.

[0015] Further, the adjusting control mechanism comprises a motor, a gear and an arc-shaped rack, the arc-shaped rack is arranged on the outer circumferential wall of the rotating plate, the driving shaft of the motor extends in the vertical direction, the gear is sleeved on the driving shaft and engaged with the arc-shaped rack.

[0016] Further, the cyclone vane is arranged on the inner circumferential wall of the distribution cavity, and the cyclone vane is arranged in an inclined manner relative to the vertical direction.

[0032] Referring to Figures 1 to 10 The embodiment discloses a gas-liquid separator 10, comprising a shell 11, a cyclone vane 13, a rotating plate 15, an adjusting control mechanism and a plurality of baffle plates 16, the shell 11 is provided with a separation cavity 12, the upper end of the separation cavity 12 is provided with an air inlet 121, the cyclone vane 13 is arranged in the separation cavity 12 to force the airflow entering the separation cavity 12 from the air inlet 121 to rotate. Wherein, the lower end plate 122 of the separation cavity 12 is provided with a gas outlet 1221, the circumferential wall of the shell 11 is provided with a liquid outlet 111 communicated with the separation cavity 12, the liquid outlet 111 is arranged close to the lower end plate 122, the rotating plate 15 is located in the separation cavity 12 and below the cyclone vane 13 in the vertical direction, and the rotating plate 15 is provided with a through hole 151, the plurality of baffle plates 16 are located in the separation cavity 12 and below the rotating plate 15 in the vertical direction. And, the plurality of baffle plates 16 are distributed equidistantly in the circumferential direction of the separation cavity 12, and the inner circumferential end of the plurality of baffle plates 16 is protrudingly arranged inside the through hole 151 and the gas outlet 1221 in the horizontal direction and encloses an exhaust hole 18, each baffle plate 16 is rotatably hinged on the lower end plate 122, and each baffle plate 16 is protrudingly provided with a limiting column 163, the rotating plate 15 is provided with a plurality of arc-shaped grooves 152, one arc-shaped groove 152 is sleeved on one limiting column 163, the adjusting control mechanism can control the rotating plate 15 to rotate around the vertical direction, so that one arc-shaped groove 152 forces one limiting column 163 to move in the radial direction and the circumferential direction of the exhaust hole 18, to adjust the size of the exhaust hole 18.

[0033] When the gas-liquid separator 10 of this embodiment performs a gas-liquid separation operation, an airflow containing liquid impurities enters the interior of the liquid separation chamber 12 from the air inlet 121 of the liquid separation chamber 12 of the housing 11. Since the liquid separation chamber 12 is provided with a swirl blade 13, the swirl blade 13 forces the airflow containing liquid impurities entering the liquid separation chamber 12 from the air inlet 121 to swirl, so that the airflow containing liquid impurities generates a circumferential velocity under the action of the swirl blade 13, and the liquid impurities are moved to the inner wall of the liquid separation chamber 12 under the entrainment of the swirling airflow. As a result, a liquid film is formed on the inner wall surface of the liquid separation chamber 12 under the action of centrifugal force, and the liquid film flows along the inner wall surface of the liquid separation chamber 12 under the action of the shear force of the airflow. At the same time, the liquid film on the inner wall surface of the liquid separation chamber 12 flows along the inner wall surface of the liquid separation chamber 12 to the water baffle 16 under the action of gravity, and the water baffle 16 guides the liquid film to the drain port 111 on the peripheral wall of the shell 11 for discharge, and the dry gas after separation of liquid impurities is discharged through the exhaust hole 18 surrounded by the inner peripheral ends of multiple water baffles 16, thereby obtaining dry gas.

[0034] Since the regulating and controlling mechanism of the gas-liquid separator 10 of this embodiment can control the rotating plate 15 to rotate in the vertical direction, an arcuate groove 152 on the rotating plate 15 forces a limiting column 163 on a water baffle 16 to move in the radial and circumferential directions of the exhaust hole 18, so as to adjust the size of the exhaust hole 18 formed by the inner circumferential ends of the multiple water baffles 16. Thus, when the humidity sensor detects that the humidity of the dry gas discharged from the exhaust hole 18 formed by the inner circumferential ends of the multiple water baffles 16 is relatively high, the regulating and controlling mechanism of the gas-liquid separator 10 of this embodiment controls the rotating plate 15 to rotate in the positive direction in the vertical direction, so that an arcuate groove 152 on the rotating plate 15 forces a limiting column 163 on a water baffle 16 to move in the radial and circumferential directions of the exhaust hole 18, so as to reduce the aperture of the exhaust hole 18 formed by the inner circumferential ends of the multiple water baffles 16, as shown in FIG. Figure 11 As shown, the gas-liquid separator 10 can separate the air flow containing liquid impurities, remove more liquid impurities, reduce the humidity of the gas, and obtain dry gas, thereby improving the gas-liquid separation effect of the air flow with higher humidity, and also improving the gas-liquid separation efficiency; when the humidity sensor detects that the humidity of the dry gas discharged from the exhaust hole 18 surrounded by the inner circumferential ends of the multiple water baffles 16 is relatively low, the regulating control mechanism of the gas-liquid separator 10 of this embodiment controls the rotating plate 15 to rotate in the opposite direction around the vertical direction, so that an arc-shaped groove 152 on the rotating plate 15 forces a limiting column 163 on a water baffle 16 to expand and move in the radial direction and circumferential direction of the exhaust hole 18, so as to enlarge the aperture of the exhaust hole 18 surrounded by the inner circumferential ends of the multiple water baffles 16, as shown in FIG. Figure 12 As shown, the gas-liquid separation effect of the airflow with lower humidity is improved while the gas-liquid separation efficiency is greatly improved.

[0035] Therefore, the gas-liquid separator 10 of the embodiment is provided with the adjustable water baffle 16, which can be adjusted according to different humidity air flows, so as to improve the gas-liquid separation effect and efficiency.

[0036] In order to quickly and smoothly drain the liquid film to the liquid outlet 111 on the peripheral wall of the shell 11, each water baffle 16 of the embodiment includes an inclined portion 161, which is arranged upwardly inclined relative to the horizontal direction, and the inner circumferential ends of the plurality of inclined portions 161 form the exhaust hole 18, so that the inclined portion 161 of the water baffle 16 can quickly and smoothly guide the separated liquid film downwardly to be discharged from the liquid outlet 111 on the peripheral wall of the shell 11, avoiding the accumulation of the liquid film, which is easy to mix with the air flow again, affecting the gas-liquid separation effect and efficiency.

[0037] In order to ensure the circumferential closed loop of the exhaust hole 18 formed by the inner circumferential ends of the plurality of water baffles 16, so that the upper inclined end of the inclined portion 161 of the water baffle 16 is overlapped above the adjacent water baffle 16 in the vertical direction in the circumferential direction of the exhaust hole 18. Specifically, the inner circumferential end of the inclined portion 161 of the water baffle 16 of the embodiment extends in an arc shape, so that the exhaust hole 18 formed by the inner circumferential ends of the plurality of water baffles 16 is arranged in an arc closed loop to improve the discharge rate of the dry gas.

[0038] In order to improve the stability and reliability of the water baffle 16 moving in the radial direction and the circumferential direction of the exhaust hole 18, each water baffle 16 of the embodiment further includes a flat portion 162 connected with the inclined portion 161, and the flat portion 162 of the water baffle 16 is located on and parallel to the lower end plate 122 of the liquid separation chamber 12.

[0039] Specifically, each water baffle 16 of the embodiment is provided with a hinge hole 164, and the inner end face of the lower end plate 122 is protrudingly provided with a plurality of rotating shafts 1222, one hinge hole 164 is rotatably sleeved on one rotating shaft 1222, so that the water baffle 16 is rotatably hinged on the lower end plate 122 of the liquid separation chamber 12. Further, one hinge hole 164 of the embodiment is located at one end of one water baffle 16 in the circumferential direction of the exhaust hole 18, and one limiting column 163 is located at the middle of one water baffle 16 in the circumferential direction of the exhaust hole 18, so as to ensure the stability and reliability of the water baffle 16 moving in the radial direction and the circumferential direction of the exhaust hole 18, while ensuring the circumferential closed loop of the exhaust hole 18 formed by the inner circumferential ends of the plurality of water baffles 16.

[0040] In order to improve the stability and reliability of the rotation of the rotating plate 15 around the vertical direction, the adjusting and controlling mechanism of the embodiment comprises the motor 14, the gear 142 and the arc-shaped rack 143, the arc-shaped rack 143 is arranged on the outer circumferential wall of the rotating plate 15, the driving shaft 141 of the motor 14 extends in the vertical direction, the gear 142 is sleeved on the driving shaft 141 and engaged with the arc-shaped rack 143, so that the motor 14 controls the driving shaft 141 to drive the gear 142 to rotate around the vertical direction, so as to drive the arc-shaped rack 143 to drive the rotating plate 15 to stably rotate around the vertical direction.

[0041] Further, the cyclone vane 13 of the embodiment is arranged on the inner circumferential wall of the separation chamber 12, and the cyclone vane 13 is arranged to be inclined and curved relative to the vertical direction, so as to force the airflow entering the separation chamber 12 from the air inlet 121 of the separation chamber 12 to rotate. And, compared with the prior art of arranging the cyclone vane on the shaft body, the cyclone vane 13 of the embodiment is directly arranged on the inner circumferential wall of the separation chamber 12, without the need for additional shaft body, and the shaftless design of the cyclone vane 13 can reduce the weight of the cyclone vane 13, thereby reducing the overall weight of the gas-liquid separator 10, and reducing the flow resistance caused by the shaft body.

[0042] In order to enhance the structural strength of the cyclone vane 13 and improve the forcing force of the airflow rotation, the height of the cyclone vane 13 in the vertical direction gradually increases from the end portion 131 of the cyclone vane 13 away from the inner circumferential wall of the separation chamber 12 to the root portion 132 of the cyclone vane 13 connected to the inner circumferential wall of the separation chamber 12. And, in order to further improve the forcing force of the airflow rotation, the number of the cyclone vane 13 of the embodiment is multiple, and the multiple cyclone vanes 13 are equally spaced in the circumferential direction of the separation chamber 12.
