Description

Technical Field

[0001] This invention relates to the field of clothing processing equipment, and specifically provides a clothing processing device. Background Technology

[0002] Existing washing machines typically remove stains from clothes by adding detergent. Detergent mainly removes stains through its chemical components. Whether the detergent can dissolve completely affects the washing effect. If the detergent cannot dissolve completely, it will remain on the clothes, causing damage.

[0003] In existing technologies, to accelerate the dissolution of detergent and the removal of stains from clothing, a gas generating device is usually introduced. The gas outlet of the gas generating device is located between the inner and outer drums. For example, the gas generating device is directly installed on the inner wall of the outer drum, and the bubbles generated by its gas outlet are directly emitted between the inner and outer drums. Alternatively, the gas generating device is located outside the outer drum, and the bubbles are introduced into the space between the inner and outer drums through a pipeline. Then, the bubbles enter the inner drum through the water permeable holes. However, the above-mentioned setups have limited effectiveness in dissolving detergent and removing stains from clothing.

[0004] To address the aforementioned issues, existing improvements have focused on modifying the gas generating device or related pipelines to increase the number of bubbles produced at the gas outlet or to generate microbubbles. While these improvements slightly enhance the removal of stains from clothing and the solubility of detergents, they have not yet achieved a level of effectiveness that satisfies users.

[0005] Accordingly, there is a need in the art for a new garment treatment device to address the problem that existing washing machines have limited effectiveness in removing stains and dissolving detergents. Summary of the Invention

[0006] The present invention aims to solve the above-mentioned technical problems, namely, to address the issue that existing washing machines have insufficient ability to remove stains from clothes and dissolve detergents.

[0007] The present invention provides a garment processing device, the garment processing device comprising: a washing drum having a cavity for receiving clothes to be washed and a water storage area; a gas generating device having a gas outlet; and a gas conveying device having an air inlet and an air outlet, the air inlet being connected to the gas outlet and the air outlet extending to the water storage area.

[0008] In the preferred embodiment of the above-mentioned clothing processing equipment, the washing drum includes an inner drum and an outer drum, the inner drum is rotatably disposed inside the outer drum, and the air outlet extends to the inner side of the inner drum.

[0009] In the preferred embodiment of the above-mentioned clothing processing equipment, the gas conveying device located on the inner side of the inner cylinder is located at the front end of the inner cylinder.

[0010] In the preferred embodiment of the above-mentioned clothing processing equipment, the gas conveying device is a pipe.

[0011] In the preferred embodiment of the above-mentioned garment processing equipment, the tube passes through the outer cylinder or the window gasket connected between the housing of the garment processing equipment and the outer cylinder, and bends downward after passing the inlet of the inner cylinder.

[0012] In the preferred embodiment of the above-mentioned garment processing equipment, the gas conveying device includes a first conveying pipe and a second conveying pipe. The first end of the first conveying pipe is the air inlet, and the second end of the first conveying pipe passes through the outer cylinder or the window gasket connected between the housing of the garment processing equipment and the outer cylinder, and passes over the inlet of the inner cylinder, and is connected to the first end of the second conveying pipe. The second end of the second conveying pipe is the air outlet.

[0013] In the preferred embodiment of the above-mentioned garment processing equipment, the second conveying pipe is a flexible hose; or the second end of the first conveying pipe is connected to the first end of the second conveying pipe via a first bearing.

[0014] In the preferred embodiment of the above-mentioned garment processing equipment, the gas conveying device includes a third conveying pipe and a turntable. The first end of the third conveying pipe is the air inlet, and the second end of the third conveying pipe passes through the outer cylinder or the window gasket connected between the housing of the garment processing equipment and the outer cylinder, and passes over the inlet of the inner cylinder. A gas chamber is formed inside the turntable, and an air outlet is formed circumferentially on the side wall of the turntable. An air inlet is formed in the middle of the rear wall of the turntable. The air inlet and the second end of the third conveying pipe are connected axially in the inner cylinder by a second bearing. After the gas passes through the air inlet and the gas chamber, it is discharged from the air outlet.

[0015] In the preferred embodiment of the above-mentioned garment processing equipment, the sidewall of the turntable smoothly transitions with the front and rear walls of the turntable, and a protrusion is formed on the front wall.

[0016] In the preferred embodiment of the above-mentioned garment processing equipment, the gas generating device is located on the outer wall of the outer cylinder or on the inner wall of the casing of the garment processing equipment; and / or the gas generating device is an air pump, a fan or a compressor.

[0017] It is understood that the clothing processing device of the present invention includes: a washing drum having a cavity for receiving clothes to be washed and a water storage area; a gas generating device having a gas outlet; and a gas conveying device having an air inlet and an air outlet, the air inlet being connected to the gas outlet and the air outlet extending to the water storage area.

[0018] This invention extends the gas outlet of the gas delivery device directly to the water storage area of ​​the garment processing equipment, directly introducing the high-energy gas generated by the gas generator into the water storage area. This forms high-energy bubbles in the washing / rinsing water, which in turn create a large number of cavitation bubbles in the water. The bursting of hundreds of billions of rigid cavitation bubbles generates a powerful impact force, effectively removing dirt from the clothes, reducing the amount of detergent used and residue, and significantly improving the stain removal and detergent dissolution effects.

Detailed Implementation

[0026] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. Those skilled in the art can make adjustments as needed to adapt to specific applications.

[0027] It should be noted that in the description of this invention, terms such as "inner," "outer," "front," "rear," "lower," "side," and "middle," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "communication" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0029] like Figures 1 to 4As shown, in order to solve the problem that the existing washing machines have insufficient ability to remove stains from clothes and dissolve detergents, the clothes processing device of the present invention includes: a washing drum 1, a gas generating device 2, and a gas conveying device 3; the washing drum 1 has a cavity for receiving clothes to be washed and a water storage area, wherein the water storage area is the area where washing water is in the cavity for receiving clothes to be washed; preferably, the washing drum 1 includes an inner drum 11 and an outer drum 12, the inner drum 11 is rotatably disposed inside the outer drum 12, and if a motor is provided on the bottom side of the outer drum 12, the drive shaft of the motor passes through the outer drum 12 and is connected to the inner drum 11, in this case, the cavity for receiving clothes to be washed is the cavity for receiving clothes in the inner drum 11, and the water storage area is the water storage area in the inner drum 11. Specifically, when the clothes processing device is a drum washing machine, the water storage area is located on the radial bottom side of the inner drum 11, and when the clothes processing device is a pulsator washing machine, the water storage area is located on the axial bottom side of the inner drum 11. The gas generating device 2 is equipped with a gas outlet 21; the gas conveying device 3 includes an inlet (not shown) and an outlet 36. The inlet is connected to the gas outlet 21, and the outlet 36 extends to the inner side of the inner cylinder 11, i.e., the water storage area of ​​the inner cylinder 11. In other words, the gas from the gas generating device 2 enters the gas conveying device 3 sequentially through the gas outlet 21 and the inlet of the gas conveying device 3, and then is discharged into the water storage area of ​​the inner cylinder 11 through the outlet 36 of the gas conveying device 3. The gas generating device 2 can take various forms, such as an air pump, a fan, or a compressor. The gas generating device 2 can introduce gas in various ways. For example, when the gas generating device 2 is located on the outer wall of the outer cylinder 12, the gas inlet of the gas generating device 2 can be connected to a vent on the housing of the clothing processing equipment through a connecting pipe; when the gas generating device 2 is located on the inner wall of the housing, the gas inlet of the gas generating device 2 can be directly connected to a vent on the housing, etc.

[0030] Furthermore, the specific forms of the clothing processing device of the present invention include various types, such as a drum washing machine, a top-loading washing machine, or a shoe washing machine. For ease of description, the clothing processing device of the present invention will be described below using a drum washing machine as an example.

[0031] Because the gas bubbles generated by the gas outlet of the existing gas generator are directly emitted between the inner and outer drums, the effect on dissolving detergent and removing stains from clothes is limited. The improvement solutions usually involve increasing the gas volume of the gas generator or improving the gas generator to produce microbubbles, but the final effect has not been significantly improved.

[0032] The applicant's research revealed that the probability of air bubbles entering the inner drum 11 from the outer drum 12 through the water-permeable holes on the inner drum 11 is very small. Furthermore, experiments have shown that even very small microbubbles, rather than large ones, have difficulty effectively entering the inner drum 11. In other words, this application found that the main reason for the poor detergent dissolution and stain removal effect on clothing is not the quantity or size of the generated bubbles, but rather that the water-permeable holes on the inner drum 11 prevent air bubbles from effectively entering the inner drum 11.

[0033] Based on the aforementioned problems not discovered by those skilled in the art, this application extends the gas outlet 36 of the gas conveying device 3 directly to the water storage area of ​​the drum washing machine, that is, the high-energy gas generated by the gas generator 2 is directly introduced into the water storage area of ​​the inner drum 11, forming high-energy bubbles in the washing / rinsing water, and then forming a large number of cavitation bubbles in the water. Hundreds of billions of rigid cavitation bubbles burst, thereby generating a powerful impact force, effectively removing dirt from clothes, reducing the amount of detergent used and residue, and significantly improving the stain removal and detergent dissolution effect.

[0034] In a preferred embodiment, the gas delivery device 3, located on the inner side of the inner drum 11, is positioned at the front end of the inner drum 11. For drum washing machines, most clothes are concentrated in the middle and rear parts of the inner drum 11, with only a small amount of clothes in the front. For pulsator washing machines, since the axis of the drum is perpendicular to the ground and the washing water usually completely soaks the clothes, the upper washing water area typically does not interfere with the clothes. Therefore, regardless of whether it is a drum washing machine or a pulsator washing machine, the above-mentioned arrangement can reduce the interference between the gas delivery device 3 and the clothes.

[0035] In this case, preferably, the gas generating device 2 is located at the front end of the outer side wall of the outer cylinder 12, or at the front end of the inner side wall of the housing, so as to reduce the length of the pipeline.

[0036] Furthermore, the outlet 36 of the gas delivery device 3 can extend to near the inner wall of the inner cylinder 11, thereby ensuring effective bubble generation while avoiding a large gap between the outlet 36 and the inner wall of the inner cylinder 11, which could lead to a large gap that could trap clothing.

[0037] The gas delivery device 3 of the present invention has various specific structures, and the present invention will describe them below with the following possible embodiments as examples.

[0038] As a first possible implementation of the specific structure of the gas conveying device 3, refer to Figure 1 and Figure 2The gas delivery device 3 is a pipe 31. That is to say, the gas generated by the gas generator 2 is directly delivered to the water storage area of ​​the inner cylinder 11 through the pipe 31. With this arrangement, the pipe 31 is small in size, so it occupies less space in the inner cylinder 11. In addition, this structure is simple and has a low production cost.

[0039] Furthermore, the tube 31 passes through the window gasket 6 connecting the casing and the outer drum 12 of the drum washing machine, and bends downward after passing over the loading port 111 of the inner drum 11. There are various ways to implement the tube 31 passing through the window gasket 6. For example, to ensure the airtightness of the washing drum 1, the tube 31 can be made of rubber hose and have an interference fit with the window gasket 6; or, a sealing ring can be placed between the tube 31 and the window gasket 6 to achieve a sealed connection.

[0040] The advantage of the above-mentioned arrangement is that, since the material of the window pad 6 is flexible and the tube 31 bends downward after passing the inlet 111 of the inner tube 11, if there is interference between the clothing and the tube 31, the window pad 6 can provide a buffer against the force on the tube 31 through its elastic deformation, thereby protecting the tube 31 from damage. In addition, it can also provide a buffer against the force on the clothing that is interfering, thereby protecting the clothing.

[0041] As a second possible implementation of the specific structure of the gas conveying device 3, refer to Figure 3 The gas conveying device 3 includes a first conveying pipe 32 and a second conveying pipe 33. The first end of the first conveying pipe 32 is the air inlet of the gas conveying device 3, which is connected to the gas outlet 21 of the gas generator 2. The second end of the first conveying pipe 32 passes through the window gasket 6 connecting the housing and the outer cylinder 12 of the garment processing equipment, and passes over the inlet 111 of the inner cylinder 11, and is connected to the first end of the second conveying pipe 33. The second end of the second conveying pipe 33 is the air outlet 36. The gas transmission process is as follows: gas enters the first conveying pipe 32 from the first end of the first conveying pipe 32, then enters the second conveying pipe 33 from the second end of the first conveying pipe 32 and through the first end of the second conveying pipe 33, and finally exits from the air outlet 36 of the second conveying pipe 33.

[0042] Wherein, the second end of the first conveying pipe 32 can extend along the axial direction of the inner cylinder 11 after passing the inlet 111 of the inner cylinder 11, and connect with the first end of the second conveying pipe 33 in the axial direction, and the second conveying pipe 33 is bent relative to itself; or the second end of the first conveying pipe 32 can be bent downward after passing the inlet 111 of the inner cylinder 11, and connect with the first end of the second conveying pipe 33 in the bending direction.

[0043] The advantages of the first conveying pipe 32's second end passing through the window gasket 6 and over the inner cylinder 11's inlet 111, as well as its specific connection method with the window gasket 6, are similar to those of the pipe body 31 passing through the window gasket 6 and over the inner cylinder 11's inlet 111, and will not be repeated here. It should be noted that the present invention, through the arrangement of the first conveying pipe 32 and the second conveying pipe 33, allows for a detachable connection between the two pipes. For example, the first end of the second conveying pipe 33 can be directly inserted (through interference fit, snap-fit, etc.) into the second end of the first conveying pipe 32, thus facilitating the maintenance and replacement of the second conveying pipe 33; or, it allows for the design of the first conveying pipe 32 and the second conveying pipe 33 into different structural forms according to the operating conditions.

[0044] To further avoid interference between the gas delivery device 3 and the clothing, which could cause damage to both, the present invention provides the following possible implementation methods.

[0045] As one possible implementation, the second delivery pipe 33 described above is a flexible hose. For example, it can be an elastic silicone hose or a corrugated hose. Since the second delivery pipe 33 is a flexible hose, when the hose collides with the clothes in the inner tube 11, the hose can deform itself to avoid damage to the hose or the clothes.

[0046] In one possible implementation, the second end of the first conveying pipe 32 and the first end of the second conveying pipe 33 are connected by a first bearing 4. Specific installation methods include: the outer ring of the first bearing 4 is pressed into the second end of the first conveying pipe 32, and the first end of the second conveying pipe 33 is disposed within the inner ring of the first bearing 4; or the outer ring of the first bearing 4 is pressed into the first end of the second conveying pipe 33, and the second end of the first conveying pipe 32 is disposed within the inner ring of the first bearing 4, etc.

[0047] The advantage of this arrangement is that it allows the second conveying pipe 33 to rotate relative to the first conveying pipe 32. When the second conveying pipe 33 interferes with the clothing, the rotation of the second conveying pipe 33 can alleviate the direct impact of the clothing on the second conveying pipe 33, thereby protecting the clothing and the pipe body 31 from damage.

[0048] Preferably, the second end of the first conveying pipe 32 is connected to the first end of the first conveying pipe 32 in the axial direction of the inner cylinder 11 by the first bearing 4. Thus, when interference occurs between the second conveying pipe 33 and the clothing, the rotation direction of the second conveying pipe 33 can be made consistent with the rotation direction of the clothing, thereby further protecting the clothing and the pipe body 31 from damage.

[0049] As a third possible implementation of the specific structure of the gas conveying device 3, refer to Figure 4The gas conveying device 3 includes a third conveying pipe 34 and a turntable 35. The first end of the third conveying pipe 34 is an air inlet, which is connected to the gas outlet 21 of the gas generating device 2. The second end of the third conveying pipe 34 passes through the window gasket 6 connected between the housing of the garment processing equipment and the outer cylinder 12, and passes over the inlet 111 of the inner cylinder 11. A gas chamber is formed inside the turntable 35. An air outlet 36 is formed circumferentially on the side wall of the turntable 35. An air inlet 351 is formed in the middle of the rear wall of the turntable 35 (as shown on the left side of the turntable 35 in the figure). The air inlet 351 is connected to the second end of the third conveying pipe 34 in the axial direction of the inner cylinder 11 by a second bearing 5. After the gas passes through the air inlet 351 and the gas chamber, it is discharged from the air outlet 36.

[0050] The gas transmission process described above is as follows: gas enters the third conveying pipe 34 through the first end of the third conveying pipe 34, then enters the gas chamber through the air inlet 351 of the turntable 35 through the second end of the third conveying pipe 34, and finally exits through the air outlet 36 of the turntable 35. Specifically, the connection between the air inlet 351 of the turntable 35 and the second end of the third conveying pipe 34 via the second bearing 5 includes: the outer ring of the second bearing 5 is pressed into the air inlet 351 of the turntable 35, and the second end of the third conveying pipe 34 is located in the inner ring of the second bearing 5; or the outer ring of the second bearing 5 is pressed into the second end of the third conveying pipe 34, and the air inlet 351 of the turntable 35 is located in the inner ring of the second bearing 5, etc.

[0051] The advantages of the third delivery pipe 34 passing through the window pad 6 and over the delivery port 111 of the inner cylinder 11, as well as its specific connection method with the window pad 6, are similar to the advantages of the pipe body 31 passing through the window pad 6 and over the delivery port 111 of the inner cylinder 11, as well as its connection method with the window pad 6, and will not be repeated here.

[0052] The advantages of the above arrangement are as follows: Since the air outlet 36 is formed on the circumferential side wall of the turntable 35, the air outlet 36 will always be located in the water storage area, regardless of the position of the turntable 35. This ensures that the rotation of the turntable 35 will not affect the generation of gas in the water storage area. Because the air inlet 351 of the turntable 35 is connected to the second end of the third conveying pipe 34 in the axial direction of the inner cylinder 11 via the second bearing 5, the rotation direction of the turntable 35 is consistent with the rotation direction of the clothing, thus avoiding damage to the clothing and related pipes. Furthermore, since the front wall of the turntable 35 (as shown on the right side of the turntable 35 in the figure) is or is almost a flat surface, and the front wall of the turntable 35 is the part that mainly contacts the clothing, it will not snag the clothing or damage it.

[0053] Furthermore, the sidewall of turntable 35 smoothly transitions to the front and rear walls of turntable 35, and a protrusion is formed on the front wall.

[0054] This design ensures that even if clothing crosses the front wall of the turntable 35 and reaches the junction between the front wall and the side wall, and between the side wall and the rear wall, the smooth transition between the side wall and the front and rear walls of the turntable 35 provides effective protection for the clothing when it comes into contact with this transition area. Furthermore, the protrusions on the front wall of the turntable 35 not only effectively protect the clothing when it reaches the front wall, but also improve the washing effect. Combined with the effect of air bubbles, this allows the detergent to dissolve fully and effectively removes dirt from the clothing.

[0055] Furthermore, it should be noted that although the above embodiments are described with the second end of the tube body 31, the first conveying tube 32, or the third conveying tube 34 passing through the window gasket 6, the arrangement can be adjusted. For example, the second end of the tube body 31, the first conveying tube 32, or the third conveying tube 34 can pass through the outer cylinder 12, etc. As long as it can extend into the front end of the inner cylinder 11, it is within the protection scope of this invention.

[0056] It should be noted that the above embodiments are merely used to illustrate the principles of the present invention and are 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.

[0057] For example, as an alternative embodiment of the present invention, although the present invention is described with the washing drum 1 including the inner drum 11 and the outer drum 12, its arrangement is not unique. For example, only one drum may be provided. In this case, the drum may be provided with a cover, and the drum may be slidably connected to the housing. For example, rollers may be provided on the drum, and guide rails may be provided on the housing. These do not deviate from the principle of the present invention, and therefore, they are all within the protection scope of the present invention.

[0058] For example, as an alternative embodiment of the present invention, although the present invention is described with the gas conveying device 3 located at the front end of the inner cylinder 11 on the inner side of the inner cylinder 11, this is not intended to limit the scope of protection of the present invention. As long as the gas outlet 36 of the gas conveying device 3 can extend into the water storage area of ​​the inner cylinder 11, its arrangement can be adjusted, such as extending the gas outlet 36 to the middle of the inner cylinder 11, etc. These do not deviate from the principle of the present invention, and therefore are all within the scope of protection of the present invention.

[0059] For example, as an alternative embodiment of the present invention, although the present invention is described as having the gas conveying device 3 bent downward after passing through the inlet 111 of the inner cylinder 11, this is not intended to limit the scope of protection of the present invention. As long as the outlet 36 of the gas conveying device 3 can extend into the water storage area of ​​the inner cylinder 11, its arrangement can be adjusted. For example, the gas conveying device 3 can pass through the inner cylinder 11 and extend directly into the water storage area in the axial direction of the inner cylinder 11. These do not deviate from the principle of the present invention, and therefore, are all within the scope of protection of the present invention.

[0060] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.
