Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a vapor-liquid separation device and an ironing machine. Background Art

[0002] The ironing machine is provided with a steam injection system, which can generate steam. The generated steam can be ejected from a steam injection head of the steam injection system, and the ejected steam can be used to iron clothes.

[0003] During the steam generation phase, the steam injection system cannot guarantee the complete conversion of water into steam, and incompletely vaporized water droplets may be entrained within the steam. Furthermore, as steam travels over increasing distances, heat dissipates, and the steam temperature drops, causing condensation and conversion to small droplets. This can result in a large number of water droplets appearing on the steam injection nozzle, causing water spray from the steam injection nozzle. This can cause large water marks on clothing, making it difficult to wear.

[0004] Based on this, it is urgent to invent a vapor-liquid separation device and an ironing machine that can solve the problem that vapor and liquid cannot be separated well. Summary of the Invention

[0063] Example 1

[0064] like Figure 1 As shown, this embodiment provides a vapor-liquid separation device 100 including a main body 1 and an output pipe 2, the main body 1 includes a separation structure 11, a vapor inlet 1121 is provided on the separation structure 11, the output pipe 2 is connected to the separation structure 11, the output pipe 2 includes a steam inlet 2131 and a steam outlet 222, the steam outlet 222 is connected to the outside of the separation structure 11 and is located above the vapor inlet 1121, and the vapor inlet 2131 is located inside the separation structure 11 and below the vapor inlet 1121. Steam enters the separation structure 11 at high speed from the steam inlet 1121, and the high-speed steam forms a high-speed cyclone steam flow in the separation structure 11. The water droplets entrained in the cyclone steam flow are separated from the water vapor under the action of the centrifugal force of the high-speed cyclone steam flow, and the separated water droplets are thrown onto the inner wall of the separation structure 11. Under the action of gravity, the water droplets fall in a spiral shape along the inner wall of the separation structure 11, and the steam with the water droplets separated enters from the steam inlet 2131 of the output pipe 2 and is discharged from the steam outlet 222 of the output pipe 2, finally achieving a better separation effect of the vapor-liquid separation device 100 on the vapor and liquid in the steam.

[0065] As a preferred solution, Figure 1 As shown, the vertical distance between the steam inlet 2131 and the gas inlet 1121 is not less than 10 mm, which can achieve a sufficient cyclonic effect on the gas-liquid mixture and improve the separation effect of the gas and liquid. However, if the vertical distance between the steam inlet 2131 and the gas inlet 1121 is too long, the overall length of the gas-liquid separation device 100 will be too long. In this embodiment, the vertical distance between the steam inlet 2131 and the gas inlet 1121 is preferably 15 mm to 20 mm. Within this range, it can not only ensure the sufficient separation effect of the gas-liquid mixture, but also ensure that the length of the gas-liquid separation device 100 is moderate, making it convenient for the gas-liquid separation device 100 to be suitable for scenes with smaller spaces and convenient for storage and transportation of the gas-liquid separation device 100. Among them, the main body 1 and the output pipe 2 can be split, and the output pipe 2 is plugged into the main body 1. By adjusting the different lengths of the output pipe 2, it is suitable for different application scenarios. The main body 1 and the output pipe 2 can also be integrally molded by injection molding, which can effectively improve the assembly efficiency of the gas-liquid separation device 100.

[0066] like Figure 1 As shown, the body 1 also includes a liquid treatment mechanism located below the separation mechanism 11. The water droplets separated by the separation mechanism 11 fall from the inner wall of the structure 11 in a spiral shape and eventually fall into the liquid treatment mechanism. The liquid stored in the liquid treatment mechanism can be discharged or reused. Specifically, as Figure 1 As shown, the liquid processing mechanism is a liquid storage structure 12, and the liquid storage mechanism 12 can store the separated liquid.

[0067] The vapor-liquid separation device 100 provided in this embodiment can be used in the steam injection system of an ironing machine. The steam injection system includes a steam generating device and a steam injection head. The steam generating device can generate steam. The outlet of the steam generating device is connected to the steam inlet 1121 of the vapor-liquid separation device 100. The steam outlet of the output pipe 2 is connected to the steam inlet end of the steam injection head. Through the vapor-liquid separation effect of the vapor-liquid separation device 100, the liquid in the steam generated by the steam generating device can be stored in the liquid storage structure 12. The dried steam enters the steam injection head from the output pipe 2 and is ejected from the steam injection head. This can prevent the steam injection head from spraying water droplets, avoid water marks on clothes, and ensure that the clothes can be worn normally.

[0068] Combine Figure 1 The structure of the separation structure 11 is described as follows. Figure 1 As shown, the separation structure 11 includes a cover 111 and a separation tube 112. The cover 111 includes a blocking portion 1111 and a first connecting portion 1112 connected to the blocking portion 1111. The output pipe 2 is connected to the blocking portion 1111. One end of the separation tube 112 is connected to the first connecting portion 1112, and the other end of the separation tube 112 is connected to the liquid storage structure 12. During the rising process of the steam after the vapor-liquid separation, condensed water is generated in the blocking portion 1111 due to heat loss. The condensed water falls off under the action of gravity and re-participates in the cyclonic separation motion driven by the high-speed cyclonic steam flow. The separated water droplets are finally gathered in the liquid storage structure 12.

[0069] If the distance between the steam inlet 2131 and the blocking portion 1111 is relatively close, the condensed water at the blocking portion 1111 will be directly sucked into the steam inlet 2131 due to the negative pressure at the steam inlet 2131, resulting in poor vapor-liquid separation. Figure 1 As shown, the steam inlet 2131 is lower than the blocking part 1111, which increases the height difference and distance of the condensed water droplets on the blocking part 1111 entering the steam inlet 2131, and can effectively prevent the condensed water droplets on the blocking part 1111 from entering the steam inlet 2131, thereby ensuring the steam-liquid separation effect of the steam-liquid separation device 100.

[0070] Specifically, if Figure 1As shown, the greater the vertical distance between the steam inlet 2131 and the blocking portion 1111, the better, which can prevent condensed water droplets on the blocking portion 1111 from entering the steam inlet 2131. Preferably, the vertical distance between the steam inlet 2131 and the blocking portion 1111 is between 5 mm and 30 mm, which can prevent the length of the vapor-liquid separation device 100 from being too long, making the length of the vapor-liquid separation device 100 moderate and suitable for use in environments with limited space.

[0071] Since there are some impurities in the gas-liquid mixture to be separated, the gas-liquid separation device 100 may form impurities accumulation in the output pipe 2 during long-term use, resulting in blockage of the channel of the output pipe 2, making it difficult for the separated gas to be discharged from the output pipe 2. In order to solve the above problem, as Figure 1 As shown, the first connection portion 1112 of this embodiment is detachably connected to the separation pipe 112, and the operator can clean the cover 111 and the output pipe 2 removed from the separation pipe 112, thereby achieving a better exhaust effect of the output pipe 2. Figure 1 As shown, the longitudinal cross-section of the inner wall of the separator tube 112 is formed of two parallel straight lines, resulting in a simple structure. This facilitates demolding during injection molding of the separator tube 112, thereby improving the molding efficiency of the separator tube 112. Furthermore, the separator tube 112 has a uniform thickness along the vertical direction, which prevents excessive stress on a localized portion of the separator tube 112 due to uneven thickness, thereby ensuring a longer life for the separator tube 112.

[0072] Specifically, if Figure 1 As shown, the first connecting portion 1112 of this embodiment is threadedly connected to the separation tube 112. The operator can remove the first connecting portion 1112 from the separation tube 112 by simply rotating the first connecting portion 1112, which is simple, convenient, and easy to operate. Of course, in other embodiments, the first connecting portion 1112 and the separation tube 112 can also be connected by screws, pins, buckles, etc., which can also achieve a detachable connection between the first connecting portion 1112 and the separation tube 112.

[0073] Specifically, if Figure 1As shown, the first connecting portion 1112 of this embodiment includes a first connecting ring 11121 and a second connecting ring 11122, each connected to the blocking portion 1111. The first connecting ring 11121 and the second connecting ring 11122 are coaxial and spaced apart. One end of the separator tube 112 is inserted between the first connecting ring 11121 and the second connecting ring 11122, and at least one of the first connecting ring 11121 and the second connecting ring 11122 is threadedly connected to the separator tube 112. The gap between the first connecting ring 11121 and the second connecting ring 11122 enables rapid pre-assembly and positioning of the separator tube 112 and the first connecting portion 1112, thereby improving the operator's ability to accurately position the first connecting portion 1112 and the separator tube 112. In addition, by providing a first connecting ring 11121 or a second connecting ring 11122 without threads, a guiding function can be achieved for the first connecting part 1112 during the rotation process, thereby preventing the operator from applying a deflected force to the first connecting part 1112, which may cause the first connecting part 1112 and the separation tube 112 to be unable to be tightened.

[0074] In order to ensure good sealing performance of the gas-liquid separation device 100 and smooth progress of the cyclone separation movement, Figure 1 As shown, the cover 111 further includes a first sealing structure 113, which is located in the gap between the first connecting ring 11121 and the second connecting ring 11122, and between the end of the output pipe 2 and the blocking portion 1111. Specifically, in order to ensure that the first sealing structure 113 has a good sealing effect at various circumferential positions of the first connecting ring 11121 and the second connecting ring 11122, as shown in FIG. Figure 1 As shown, the first sealing structure 113 is a sealing ring, which is sleeved on the outer circumference of the first connecting ring 11121 to further improve the sealing effect of the cover body 111 and the separation tube 112 at the contact position.

[0075] The liquid stored in the liquid storage structure 12 will form a water vortex under the action of the cyclonic steam flow. The edge of the water vortex will produce higher and larger water splashes. The splashing water may escape from the steam inlet 2131 along the cyclonic steam flow. In order to solve the above problems, Figure 1 As shown, an annular baffle 1122 is provided on the inner wall of the separation tube 112, and the annular baffle 1122 is used to prevent the liquid in the liquid storage structure 12 from splashing into the output tube 2. In other embodiments, the annular baffle 1122 can also be provided on the inner wall of the liquid storage structure 12 to also prevent the liquid in the liquid storage structure 12 from splashing into the output tube 2.

[0076] As a preferred solution, Figure 1As shown, one end of the annular baffle 1122 is connected to the inner wall of the separation tube 112, and the other end of the annular baffle 1122 extends toward the liquid storage structure 12. The annular baffle 1122 is inclined from top to bottom toward the center line of the main body 1, and the opening surrounded by the lower end of the annular baffle 1122 is smaller, which can achieve the following effects: 1) It can weaken the steam flow intensity of the vortex entering the liquid storage structure 12; 2) It can effectively weaken the rotational motion of the water vortex, reduce the water level height at the edge when the liquid rotates, and reduce the risk of water splashes escaping from the steam inlet 2131. The flange 213 can block the water splashes at the edge; 3) The annular baffle 1122 can gather the water droplets above it to better enter the liquid storage structure 12. Specifically, the cross-sectional area of the hole formed at the other end of the annular baffle 1122 is 1 / 9 to 1 / 3 of the cross-sectional area of the internal space of the separation tube 112. While ensuring that the separation tube 112 can flow into the liquid storage structure 12, it can also prevent water splashes in the liquid storage structure 12 from entering the steam inlet 2131, among which 1 / 4 is preferred.

[0077] As a preferred solution, the distance from the center of the steam inlet 1121 to the lower end of the annular baffle 1122 along the vertical direction is a first distance L1, and the distance from the center of the steam inlet 1121 to the steam inlet 2131 along the vertical direction is a second distance L2, and L2 / L1 is 2 / 7 to 1 / 2, which can achieve sufficient cyclone of the vapor-liquid mixture and ensure that the length of the vapor-liquid separation device 100 is moderate.

[0078] Combine Figure 1 The structure of the liquid storage structure 12 is described as follows. Figure 1 As shown, the liquid storage structure 12 includes a liquid storage tube 121, a second connecting part 122 and a buffer part 123. The second connecting part 122 and the buffer part 123 are respectively located at the two ends of the liquid storage tube 121. The second connecting part 122 is connected to the end of the separation tube 112 away from the cover body 111. The buffer part 123 is a hemispherical structure. The hemispherical structure of the buffer part 123 makes the rotation of the liquid smoother, reduces the generation of splashes, and further avoids splashing water from overflowing from the steam outlet 222.

[0079] like Figure 1As shown, the separation tube 12 also includes a drainage structure 125 connected to the separation tube 12. When the water volume of the liquid storage structure 12 reaches a certain level, the stored liquid will be discharged along the drainage structure 125 to avoid affecting the vapor-liquid separation effect of the vapor-liquid separation device 100. As a preferred embodiment, in order to avoid this, the drainage structure 125 also includes a sealing plug. The sealing plug is blocked at the outlet of the drainage structure 125, which can prevent the liquid in the liquid storage structure 12 from flowing out freely and causing a short circuit in adjacent electrical components, thereby ensuring the safety of the use of the vapor-liquid separation device 100 and the personal safety of the user. In addition, a solenoid valve can be set on the drainage structure 125 or on the pipeline connected to the drainage structure 125, and a liquid level detection device can be set on the liquid storage tube 121. When the liquid level detection device detects that the liquid in the liquid storage tube 121 exceeds a preset height (maximum height), the liquid level detection device controls the solenoid valve to open, and the drainage structure 125 discharges the liquid in the liquid storage tube 121, ensuring a good vapor-liquid separation effect of the vapor-liquid separation device 100.

[0080] When the gas-liquid separation device 100 is used in an ironing machine, the liquid used in the ironing machine is usually tap water from a faucet. Since scale will form in tap water after long-term use, the drainage structure 125 is easily clogged by scale, resulting in clogging of the drainage structure 125. In order to solve the above problem, Figure 1 As shown, the second connecting portion 122 is detachably connected to the end of the separation tube 112 away from the cover 111, allowing the liquid storage structure 12 and the separation tube 112 to be separated and cleaned separately, ensuring relatively smooth drainage of the liquid discharge structure 125. Specifically, the second connecting portion 122 is threadedly connected to the end of the separation tube 112 away from the cover 111, allowing the operator to remove the liquid storage structure 12 from the separation tube 112 with a simple operation, making it convenient for the operator to remove the liquid storage structure 12 from the separation tube 112 in a narrow space.

[0081] Specifically, if Figure 1As shown, the second connecting portion 122 includes a locking section 1221 and a connecting section 1222, one end of the connecting section 1222 away from the locking section 1221 is connected to the liquid storage tube 121, the locking section 1221 is arranged around the outer periphery of the liquid storage tube 121 and is spaced apart from the liquid storage tube 121, and the end of the separation tube 112 away from the cover body 111 is inserted into the gap between the locking section 1221 and the liquid storage tube 121 and is threadedly connected to the locking section 1221. When the operator rotates the liquid storage structure 12, the liquid storage tube 121 facing the locking section 1221 can guide the rotation of the liquid storage structure 12, avoiding the second connecting portion 122 and the separation tube 112 from being unable to be screwed into place due to uneven force applied by the operator, ensuring a good connection between the second connecting portion 122 and the separation tube 112, preventing the second connecting portion 122 and the separation tube 112 from loosening, and preventing the separator 100 from leaking during use.

[0082] As a preferred solution, Figure 1 As shown, the liquid storage structure 12 further includes a second sealing structure 124 , which is located between the end of the separation tube 112 away from the cover body 111 and the connecting section 1222 , and can further prevent the separator 100 from leaking during use.

[0083] like Figure 2 and Figure 3 As shown, the vapor-liquid separation device 100 also includes an input pipe 114, which is connected to the outer wall of the separation tube 112. An input pipe channel 1141 is opened on the input pipe 114, and one end of the input pipe channel 1141 is connected to the vapor inlet 1121, and the other end of the input pipe channel 1141 can be connected to the vapor-liquid mixture. The vapor-liquid mixture enters the vapor inlet 1121 through the input pipe channel 1141 and further enters the interior of the separation tube 112.

[0084] As a preferred solution, Figure 2 As shown, the separation structure 11 further includes a reinforcing rib 115 , and the input pipe 114 and the separation pipe 112 are connected via the reinforcing rib 115 . The reinforcing rib 115 can provide stable support for the input pipe 114 .

[0085] As a preferred solution, Figure 3As shown, the longitudinal cross-section of the input pipe channel 1141 includes an outer guide surface 11411 and an inner guide surface 11412. The inner guide surface 11412 is closer to the centerline of the body 1. The outer guide surface 11411 is tangent to the contour line of the cross-section of the inner wall of the separation tube 112, and the inner guide surface 11412 is parallel to the outer guide surface 11411. The vapor-liquid mixture entering through the input pipe channel 1141 can flow along the inner wall of the separation tube 112 into the interior of the separation tube 112, facilitating the formation of a cyclonic state for the incoming vapor-liquid mixture and improving the degree of vapor-liquid separation of the vapor-liquid mixture.

[0086] As a preferred embodiment, the diameter of input pipe channel 1141 gradually decreases from the free end to the gas inlet 1121. This increases the pressure of the vapor-liquid mixture upon entry into separation tube 112, improves the initial velocity of the vapor-liquid mixture upon entry, enhances the cyclonic effect of the vapor-liquid mixture, and further enhances the vapor-liquid separation effect. To prevent the vapor-liquid mixture from losing kinetic energy within input pipe 114 and ensure that the vapor-liquid mixture fully cyclones within separation tube 112, the length of input pipe channel 1141 is 1 / 2 to 1 / 3 the diameter of separation tube 112.

[0087] Example 2

[0088] The output pipe 2 in the vapor-liquid separation device 100 in Example 1 is a single tube. Since the portion of the output pipe 2 extending outside the main body 1 needs to be connected to the hoses of other components, the input and output ends of the output pipe 2 are relatively small in size. The smaller diameter of the steam inlet 2131 will result in a larger negative pressure at the steam inlet 2131, which will cause water droplets at the steam inlet 2131 to be easily sucked into the output pipe 2, resulting in poor vapor-liquid separation effect of the vapor-liquid mixer 100.

[0089] In order to solve the above problems, Figure 4 As shown, the output pipe 2 of the vapor-liquid separation device 100 of this embodiment includes a first-level output pipe 21 and a second-level output pipe 22. The first-level output pipe 21 is connected to the separation structure 11 and is located inside the separation structure 11. A steam inlet 2131 is provided on the first-level output pipe 21. The second-level output pipe 22 is connected to the separation structure 11 and partially extends into the first-level output pipe 21. A steam outlet 222 is provided on the second-level output pipe 22. A steam inlet opening 221 is provided at the end of the second-level output pipe 22 extending into the first-level output pipe 21. The steam inlet 2131 is lower than the steam inlet opening 221, and the diameter of the steam inlet 2131 is larger than the diameter of the steam outlet 222. Since the diameter of the steam inlet 2131 is large, the negative pressure of the steam inlet 2131 is low, and the steam inlet 2131 is some distance away from the steam outlet 222, it is difficult for water droplets near the steam inlet 2131 to be sucked into the steam inlet 2131, so it is difficult for water droplets to enter the secondary output pipe 22 and be discharged, which can further ensure that the steam-liquid separation device 100 has a better steam-liquid separation effect.

[0090] Specifically, in order to effectively reduce the negative pressure of the steam inlet 2131, in this embodiment, the diameter of the steam inlet 2131 is preferably 1.5 to 4 times the diameter of the steam outlet 222. Specifically, the diameter of the steam inlet 2131 in this embodiment is 4.5 mm to 12 mm.

[0091] In order to further reduce the possibility of water droplets at the steam inlet 2131 entering the steam inlet opening 221, in this embodiment, the distance between the steam inlet opening 221 and the steam inlet 2131 is 2 / 3 to 5 / 6 of the length of the first-level output pipe 21. Since the steam inlet opening 221 is far away from the steam inlet 2131, even if some water droplets at the steam inlet 2131 enter the first-level output pipe 21, the water droplets cannot reach the steam inlet opening 221 due to their own gravity during the operation of the longer path. The possibility of water droplets at the steam inlet 2131 entering the steam inlet opening 221 can be further reduced, thereby ensuring a better vapor-liquid separation effect of the vapor-liquid separation device 100.

[0092] As a preferred solution, Figure 4 As shown, the primary output pipe 21 includes a third connecting portion 211, a separation portion 212, and a flange 213. The third connecting portion 211 is connected to the separation structure 11, and one end of the separation portion 212 is connected to the third connecting portion 211. The flange 213 is provided at the end of the separation portion 212 away from the third connecting portion 211. The flange 213 is inclined from top to bottom in a direction away from the centerline of the body 1. The flange 213 can cause the water droplets separated by centrifugal motion to be thrown outward and downward, away from the steam inlet 2131, making the steam inlet 2131 drier and ensuring the vapor-liquid separation effect of the vapor-liquid separation device 100.

[0093] The distance between the center of the steam inlet 1121 and the upper end of the flange 213 along the vertical direction is a third distance L3, and the distance between the upper end of the flange 213 and the lower end of the flange 213 along the vertical direction is a fourth distance L4, where L4 / L3 is 1 / 8 to 1 / 20, which can ensure that the steam after sufficient centrifugal movement is discharged from the steam inlet 2131 in a relatively dry state.

It should be understood by those skilled in the art that the present invention is not limited to the above-described embodiments, which are merely illustrative of the principles of the present invention.
