[0028] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0029] Reference Figures 1 to 4In order to solve the problem that the steam-water separation effect of the existing gas-liquid separation device is poor and it is easy to cause heat loss and affect the steam amount, the gas-liquid separation device of the present invention includes an open shell 11, a cover body 12 and an impeller 2. The cover body 12 is arranged on the shell 11 so as to open and close the opening. A steam inlet 13 is arranged at the bottom of the shell 11, and a steam outlet 14 is arranged on the cover body 12. The impeller 2 is rotatably arranged in the shell 11. The rotation axis of the impeller 2 is inclined toward the steam inlet 13 so that there is an angle a between the rotation axis of the impeller 2 and the cross-section of the steam inlet 13, 0°<angle a<90°, after the steam-water mixture entering the shell 11 from the steam inlet 13 collides and drives the impeller 2 to rotate to separate water and steam, the steam is discharged from the steam outlet 14.
[0030] The advantages of the above arrangement are that the gas-liquid separation device of the present invention will use steam to hit and drive the impeller 2 to rotate, and the water droplets hitting the impeller 2 will be thrown out by the impeller 2 along the tangential direction, thereby separating the steam and water in the steam-water mixture, and the steam is discharged from the steam outlet 14. In order to achieve a better separation effect, the rotation axis of the impeller 2 is tilted toward the steam inlet 13, so that there is an angle a between the rotation axis of the impeller 2 and the cross section of the steam inlet 13, thereby increasing the contact area between the surface of the impeller 2 and the steam-water mixture, and enhancing the water separation effect. The rotation axis of the impeller 2 is tilted toward the steam inlet 13 at a certain angle, but not completely perpendicular to it, which reduces the problem of poor heat conduction efficiency and increased condensation time of steam in the shell 11 caused by the addition of the impeller 2, thereby ensuring the purity of the separated steam, the total amount of steam and the flow rate of the steam, and maintaining a balance between the steam purity and the steam flow rate.
[0031] Reference Figures 1 to 4 In a possible embodiment, the gas-liquid separation device includes an open shell 11, a cover 12 and an impeller 2. The cover 12 is arranged on the shell 11 in an openable manner. A steam inlet 13 is arranged at the bottom of the shell 11. The outside of the steam inlet 13 is connected to a steam generator. The steam generated by the steam generator enters the shell 11 through the steam inlet 13. The cover 12 is provided with a steam outlet 14 arranged opposite to the steam inlet 13. The impeller 2 is rotatably arranged on the side wall of the shell 11 and is located near the steam inlet 13. The rotation axis of the impeller 2 is inclined toward the steam inlet 13 so that an angle a is formed between the rotation axis of the impeller 2 and the cross section of the steam inlet 13, and 0°<angle a<90°. Preferably, 5°<angle a<60°. Optionally, the angle a is any one of 10°, 12°, 15°, 20°, 25°, 30°, 40°, and 50°. Of course, those skilled in the art can set the specific value of the angle a as needed, as long as 0°<angle a is less than 90°, and it falls within the protection scope of the present invention.
[0032] After the steam generator is working, the steam-water mixture is sprayed into the housing 11 from the steam inlet 13, and the steam-water mixture hits the impeller 2 and drives the impeller 2 to rotate. In this process, water will be thrown out by the impeller 2 along the tangential direction, and the remaining steam will enter the clothing care machine along the steam outlet 14 on the cover 12 to care for the clothes. Since the rotation axis of the impeller 2 is inclined toward the steam inlet 13, the contact area between the impeller 2 and the steam is increased, thereby improving the steam separation effect. At the same time, the speed of the water vapor flow is guaranteed, thereby ensuring the balance between the contact area between the impeller 2 and the water vapor and the water vapor flow rate, which can make the water vapor more pure and discharge the water vapor faster, reducing heat loss, improving heat conduction efficiency, reducing the condensation of water vapor in the housing 11, and ensuring the amount of steam required for clothing care. The relative arrangement of the steam inlet 13 and the steam outlet 14 further increases the flow rate of the steam and reduces heat loss.
[0033] Reference Figure 2 In order to further ensure the rotation stability of the impeller 2, the gas-liquid separation device further includes a first rotating shaft 31, a bearing 32 and a bearing seat 33. The bearing 32 is installed in the bearing seat 33, and the bearing seat 33 is installed on the side wall of the housing 11. The first rotating shaft 31 is installed on the bearing 32, so that the first rotating shaft 31 rotates on the bearing 32, and the impeller 2 is installed on the first rotating shaft 31, thereby improving the rotation stability of the impeller 2. Furthermore, in order to make the impeller 2 more stable, a shaft shoulder is provided on the first rotating shaft 31, and a baffle 34 is provided at the end of the first rotating shaft 31. The impeller 2 is located between the shaft shoulder and the baffle 34, so that the position of the impeller 2 can be fixed. The shaft shoulder and the baffle 34 limit the impeller 2 to prevent the impeller 2 from escaping from the first rotating shaft 31 during rotation and causing danger.
[0034] Further, refer to Figure 1 and Figure 2The shell 11 is trapezoidal in shape as a whole. A drain port 15 is provided on the bottom plate of the shell 11 so that the separated water can be discharged from the shell 11 through the drain port 15. In order to enable the water to be discharged quickly and not to gather at the bottom of the shell 11, the bottom plate is set to gradually tilt downward from high to low toward the drain port 15 so that all the water on the bottom plate flows toward the drain port 15, thereby keeping the bottom plate dry. Furthermore, the temperature of the cover 12 is relatively low, and the water vapor will condense into water droplets after encountering the cover 12. Once the water droplets gather on the cover 12 for a long time, the problem of odor will occur. The top of the shell 11 has an inclined surface, and the opening of the shell 11 is set on the trapezoidal inclined surface. When the cover 12 is covered on the opening, the water droplets can flow obliquely downward along the cover 12 into the shell 11, and then be discharged from the drain port 15. Optionally, a water flow trough for guiding the water to flow down is provided on the cover 12, and the water can quickly flow to the bottom of the shell 11 along the water flow trough, thereby preventing the water from gathering on the cover 12. However, it should be noted that the specific shape of the housing 11 is not limited to a trapezoid, and it can also be a polygon of other shapes, or other shapes other than a polygon. Those skilled in the art can set the shape of the housing 11 as needed, and all of them fall within the protection scope of the present invention. In addition, the present invention does not set the specific shape of the cover plate 12, as long as the cover plate 12 can close the housing opening, and all of them fall within the protection scope of the present invention.
[0035] Reference Figure 5 , further, the gas-liquid separation device also includes a gas-liquid separation plate 4, the gas-liquid separation plate 4 is arranged in the housing 11, the steam inlet 13 and the impeller 2 are located on one side of the gas-liquid separation plate 4, and the steam outlet 14 is located on the other side of the gas-liquid separation plate 4. After the steam-water mixture is separated from the water at the impeller 2, a small amount of large water droplets may be mixed in the remaining steam. The gas-liquid separation plate 4 can filter the large water droplets in the steam, isolate the large water droplets mixed in the steam from the outside and prevent them from passing through the gas-liquid separation plate 4 to enter the steam outlet 14, and prevent too many large water droplets mixed in the steam from affecting the nursing effect. Further, the gas-liquid separation plate 4 is a microporous material, such as a sponge plate, a mesh plate, etc. The shape of the gas-liquid separation plate 4 can be square, round or triangular, etc. The person skilled in the art can set the material and shape of the gas-liquid separation plate 4 according to the needs, as long as there are small holes on it that can only allow steam to pass through, and they all fall within the protection scope of the present invention.
[0036] When the amount of steam is relatively small, the impeller 2 can separate the steam relatively well. However, if the steam continues to be filtered through the gas-liquid separation plate 4, the obstruction of the steam by the gas-liquid separation plate 4 will have a certain impact on the steam rate, thereby causing large heat loss of the steam, reducing the steam output, and worsening the clothing care effect. Therefore, in order to reduce the impact of the gas-liquid separation plate 4 on the steam flow rate, the gas-liquid separation plate 4 is flipably arranged in the shell 11 so that the gas-liquid separation plate 4 can be stored on the side wall of the shell 11 or unfolded. When the amount of steam is relatively small, the gas-liquid separation plate 4 is stored on the side wall of the shell 11 and no longer filters the steam. When the amount of steam is relatively large, the gas-liquid separation plate 4 is unfolded to filter the steam.
[0037] Specifically, the gas-liquid separation device further includes a second rotating shaft and a driving device, the gas-liquid separation plate 4 is connected to the second rotating shaft, the housing 11 is provided with a rotating shaft hole, the second rotating shaft is inserted into the rotating shaft hole, so that the second rotating shaft can rotate in the rotating shaft hole, the gas-liquid separation plate 4 can be rotatably arranged on the housing 11 through the second rotating shaft, and the gas-liquid separation device further includes a driving device, and optionally, the driving device is a motor, and the motor is in driving connection with the second rotating shaft, so that the gas-liquid separation plate 4 can be driven to flip, so that it is collected on the side wall of the housing 11, or the gas-liquid separation plate 4 is flipped and unfolded to the top of the steam inlet 13. When the steam flow rate is greater than the preset flow rate, the motor is controlled to drive the gas-liquid separation plate 4 to flip to the top of the steam inlet 13, and the steam separated by the impeller 2 is filtered through the gas-liquid separation plate 4. When the steam flow rate is less than the preset flow rate, the impeller 2 can meet the steam separation needs, and there are fewer large water droplets mixed in the steam. Therefore, flipping the gas-liquid separation plate 4 and collecting it on the side wall of the housing 11 can reduce the influence of the gas-liquid separation plate 4 on the steam flow rate and does not affect the steam flow.
[0038] In summary, the gas-liquid separation device of the present invention separates steam and water by means of an impeller 2 tilted toward the steam inlet 13, so as to achieve a balance between steam purity and steam flow rate. On this basis, a reversible gas-liquid separation plate 4 is used to further increase the steam flow rate, reduce heat loss, and improve the steam care effect.
[0039] As stated in the first paragraph of this section, the above implementation mode is only used to illustrate the principles of the present invention and is not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above structure so that the present invention can be applied to more specific application scenarios.
[0040] In addition, the present invention also provides a clothing care machine and a control method for the clothing care machine. The clothing care machine includes the gas-liquid separation device described in any of the above embodiments.
[0041] Specifically, the clothing care machine includes a gas-liquid separation device, which includes an open shell 11, a cover 12 and an impeller 2. The cover 12 is arranged on the shell 11 in an openable and closable manner. A steam inlet 13 is arranged at the bottom of the shell 11, and a steam outlet 14 is arranged on the cover 12. The impeller 2 is rotatably arranged in the shell 11, and the rotation axis of the impeller 2 is inclined toward the steam inlet 13 so that an angle a is formed between the rotation axis of the impeller 2 and the cross section of the steam inlet 13, 0°<angle a<90°, and the steam-water mixture entering the shell 11 from the steam inlet 13 drives the impeller 2 to rotate and separate water and steam. The gas-liquid separation plate 4 is disposed in the housing 11, and the second rotating shaft is rotatably disposed on the housing 11. The driving device is in driving connection with the second rotating shaft so that the gas-liquid separation plate 4 can be turned over and collected on the side wall of the housing 11 or unfolded. The steam inlet 13 and the impeller 2 are located on one side of the gas-liquid separation plate 4, and the steam outlet 14 is located on the other side of the gas-liquid separation plate 4. The steam inlet 13 is provided with a flow sensor for detecting the steam flow of the steam inlet 13. The clothing care machine detects the steam flow of the steam inlet 13 through the flow sensor.
[0042] The control method of the clothing care machine includes:
[0043] Get the steam flow rate of the steam inlet;
[0044] When the steam flow rate is greater than the preset flow rate, the control motor drives the gas-liquid separation plate to expand;
[0045] When the steam flow rate is less than or equal to the preset flow rate, the control motor drives the gas-liquid separation plate to be stored on the side wall of the shell.
