Description

Technical Field

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

[0002] Existing washing machines generally only have an outer drum window gasket. Because the gap between the outer drum window gasket and the door observation window is large, clothes can easily get into the gap during the washing process. When the washing speed is low, clothes tend to pile up, resulting in poor washing effect. Furthermore, the clothes piled up between the door observation window and the outer drum window gasket pose a safety hazard to the gasket and door lock.

[0003] In view of this, the present invention is proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a door limiting device that can prevent clothing from being embedded and piled up in the gap between the outer cylinder window pad and the machine door observation window.

[0005] A second objective of the present invention is to provide a garment processing device.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0007] The door limiting device includes an inner cylinder window pad, the first end of which is connected to the opening of the inner cylinder, and the second end of which abuts against the inner convex surface of the machine door observation window.

[0008] By setting an inner cylinder window gasket and using the structure where the first end of the inner cylinder window gasket is connected to the opening of the inner cylinder and the second end of the inner cylinder window gasket abuts against the convex surface inside the machine door observation window, the inner cylinder window gasket seals the angle gap between the outer cylinder window gasket and the machine door observation window, thereby preventing clothes from getting stuck in this angle gap.

[0009] Furthermore, the second end of the inner barrel window gasket also has an extension that extends toward the outer barrel window gasket.

[0010] When the washing machine door is opened, there is an angled opening between the inner drum gasket and the outer drum gasket when viewed from the outside. When clothes are loaded, they may get stuck in this angled opening. Therefore, in order to seal this angled opening, the second end of the inner drum gasket has an extension that extends circumferentially towards the outer drum gasket along the observation window of the machine door, thereby using the extension of the inner drum gasket to seal the angled opening between the inner drum gasket and the outer drum gasket.

[0011] Furthermore, a first ball bearing is provided on the extension of the second end of the inner cylinder window gasket along the circumference of the machine door observation window. The first ball bearing is embedded in the extension of the second end of the inner cylinder window gasket, and the first ball bearing part is exposed on the outer side of the extension of the second end of the inner cylinder window gasket.

[0012] Since the extension of the inner cylinder window gasket extends circumferentially from the machine door observation window to the outer cylinder window gasket, and the extension of the inner cylinder window gasket will rub against the machine door observation window when rotating, in order to reduce friction, a plurality of first ball bearings are provided on the extension of the second end of the inner cylinder window gasket along the circumferential direction of the machine door observation window. The first ball bearings are embedded in the extension of the second end of the inner cylinder window gasket, and the first ball bearings are partially exposed on the outer side of the extension of the second end of the inner cylinder window gasket. Through the rolling contact between the first ball bearings and the machine door observation window in the circumferential direction, friction is reduced and the service life of the equipment is improved.

[0013] Furthermore, more than half of the first ball is embedded in the recess of the extension of the inner cylinder window gasket, and the first ball can rotate relative to the extension of the inner cylinder window gasket.

[0014] By setting recesses on the extension of the inner cylinder window gasket in an amount equal to the number of first ball bearings, more than half of the first ball bearings are embedded in the recesses. The first ball bearings are fitted with the recess wall with a clearance, so that the recesses can both restrain the first ball bearings from falling out and allow the first ball bearings to rotate within the recesses. This allows the first ball bearings to make circumferential rolling contact with the machine door observation window. Since the first ball bearings protrude from the extension of the inner cylinder window gasket, circumferential friction between the extension of the inner cylinder window gasket and the machine door observation window can be reduced or avoided.

[0015] Two first ball bearings can be set, and the diameters of the two first ball bearings are different, with the first ball bearing closer to the machine door having a larger diameter.

[0016] Furthermore, to ensure better equipment operation, another structure is adopted. The inner cylinder window gasket also includes a liner and rollers. The liner is located on the outside of the extension of the second end of the inner cylinder window gasket. Multiple rollers are evenly arranged around the circumference of the machine door observation window. The outer end of the roller is provided with a second ball that can rotate relative to the roller. The inner end of the roller is fixed to the extension of the second end of the inner cylinder window gasket. The liner is provided with an annular groove. The annular groove opens on one side facing the extension of the second end of the inner cylinder window gasket. The outer end of the roller and the second ball are located in the annular groove of the liner.

[0017] The gasket is in circumferential contact with the machine door observation window and remains relatively stationary. The gasket is provided with an annular groove, and multiple rollers are evenly arranged along the circumference of the machine door observation window. The inner end of the roller is fixed to the extension of the second end of the inner cylinder window gasket, and the outer end of the roller is provided with a second ball that can rotate relative to the roller. The second ball and part of the roller extend into the annular groove from the opening of the gasket. When the extension of the inner cylinder window gasket rotates with the inner cylinder, it drives the roller to rotate. The arrangement of the second ball achieves rolling contact between the second ball and the gasket, reducing friction.

[0018] Furthermore, to prevent the pad from separating from the roller, the roller includes an outer end, a connecting part, and an inner end. The diameter of the outer end is larger than that of the connecting part, and the opening size of the annular groove of the pad is smaller than the diameter of the outer end of the roller. The outer end of the roller and the part of the connecting part near the outer end are located within the annular groove of the pad. The fit between the large-diameter outer end of the roller and the small-sized opening of the annular groove of the pad prevents the pad from separating from the roller.

[0019] Furthermore, in order to reduce the frictional loss between the opening side of the annular groove of the liner and the roller, a collar that can rotate relative to the roller is provided on the roller connection part, and the collar makes rolling contact with the opening side of the annular groove of the liner.

[0020] Furthermore, the first end of the inner cylinder window gasket is fixedly or slidably connected to the opening of the inner cylinder.

[0021] Furthermore, to facilitate observation of the washing process of clothes inside the washing machine drum, the inner drum window gasket is a transparent gasket.

[0022] The present invention also proposes a garment processing device, including the aforementioned door limiting device.

[0023] By installing the aforementioned door limiting device on the garment handling equipment, it is possible to prevent the laundry items in the inner drum from getting stuck in the angled gap between the outer drum window gasket and the machine door observation window during washing, and to minimize the friction between the door limiting device and the machine door observation window.

[0024] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0025] This invention relates to a door limiting device and a garment handling equipment. The door limiting device includes an inner cylinder window pad, with a first end connected to the opening of the inner cylinder and a second end abutting against the inner convex surface of the machine door's observation window. By setting the inner cylinder window pad and utilizing the structure where the first end of the inner cylinder window pad is connected to the opening of the inner cylinder and the second end of the inner cylinder window pad abuts against the inner convex surface of the machine door's observation window, the inner cylinder window pad seals the angled gap between the outer cylinder window pad and the machine door's observation window, thereby preventing garments from getting stuck in this angled gap.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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 mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0040] Example 1

[0041] like Figure 1 As shown, the door limiting device of the present invention includes an inner cylinder window pad 5 and an outer cylinder window pad 6 double window pads. The first end of the inner cylinder window pad 5 is connected to the opening of the inner cylinder 3, and the second end of the inner cylinder window pad 5 abuts against the inner convex surface of the observation window 2 of the machine door 1.

[0042] By setting an inner cylinder window pad 5 and using the structure where the first end of the inner cylinder window pad 5 is connected to the opening of the inner cylinder 3 and the second end of the inner cylinder window pad abuts against the inner convex surface of the observation window 2 of the machine door 1, the inner cylinder window pad 5 seals the angle gap between the outer cylinder window pad 6 and the observation window 2 of the machine door 1, thereby preventing clothes from getting stuck in this angle gap.

[0043] Example 2

[0044] This embodiment is an improvement on Embodiment 1.

[0045] like Figure 2 As shown, in this embodiment, the second end of the inner cylinder window gasket 5 also has an extension 7, which extends toward the outer cylinder window gasket 6.

[0046] When the washing machine door 1 is opened, there is an angled opening between the inner drum window gasket 5 and the outer drum window gasket 6 when viewed from the outside of the washing machine. When clothes are put in, the clothes may get stuck in the angle between the inner drum window gasket 5 and the outer drum window gasket 6. Therefore, in order to seal this angled opening, the second end of the inner drum window gasket 5 also has an extension 7. The extension 7 extends circumferentially towards the outer drum window gasket 6 along the observation window 2 of the door 1, thereby using the extension 7 of the inner drum window gasket 5 to seal the angled opening between the inner drum window gasket 5 and the outer drum window gasket 6.

[0047] A first ball bearing 8 is provided around the observation window 2 of the machine door 1 on the extension 7 at the second end of the inner cylinder window pad 5. The first ball bearing 8 is embedded in the extension 7 at the second end of the inner cylinder window pad 5, and part of the first ball bearing 8 is exposed on the outer side of the extension 7 at the second end of the inner cylinder window pad 5.

[0048] Since the extension 7 of the inner cylinder window pad 5 extends circumferentially from the observation window 2 of the machine door 1 to the outer cylinder window pad 6, and the extension 7 of the inner cylinder window pad 5 will rub against the observation window 2 of the machine door 1 when rotating, in order to reduce friction, a plurality of first ball bearings 8 are provided on the extension 7 at the second end of the inner cylinder window pad 5 along the circumferential direction of the observation window 2 of the machine door 1. The first ball bearings 8 are embedded in the extension 7 at the second end of the inner cylinder window pad 5, and part of the first ball bearings 8 are exposed on the outer side of the extension 7 at the second end of the inner cylinder window pad 5. Through the rolling contact between the first ball bearings 8 and the observation window 2 of the machine door 1 in the circumferential direction, friction is reduced and the service life of the equipment is improved.

[0049] More than half of the first ball bearing 8 is embedded in the recess of the extension 7 of the inner cylinder window gasket 5, and the first ball bearing 8 can rotate relative to the extension 7 of the inner cylinder window gasket 5.

[0050] By providing recesses on the extension 7 of the inner cylinder window pad 5 in the same number as the number of first ball bearings 8, more than half of the first ball bearings 8 are embedded in the recesses, and the first ball bearings 8 are fitted with the recess wall with a clearance, so that the recesses can both restrain the first ball bearings 8 from falling off and allow the first ball bearings 8 to rotate within the recesses, thereby making the first ball bearings 8 roll in circumferential contact with the observation window 2 of the machine door 1. Since the first ball bearings 8 protrude from the extension 7 of the inner cylinder window pad 5, the circumferential friction between the extension 7 of the inner cylinder window pad 5 and the observation window 2 of the machine door 1 can be reduced or avoided.

[0051] The first ball bearing 8 can rotate one or more times. In this embodiment, for example... Figure 2 As shown, two rings of first ball bearings 8 are set, and the diameters of the two rings of first ball bearings 8 are different, with the diameter of the first ball bearing 8 closer to the machine door 1 being larger.

[0052] Example 3

[0053] This embodiment is an improvement on Embodiment 1.

[0054] Combination Figure 3 , 4 As shown, to further ensure better equipment operation, this embodiment adopts another structure. The inner cylinder window pad 5 also includes a liner 9 and rollers 10. The liner 9 is disposed on the outside of the extension 7 at the second end of the inner cylinder window pad 5. Multiple rollers 10 are evenly arranged circumferentially along the observation window 2 of the machine door 1. The outer end of the roller 10 is provided with a second ball bearing 11 that can rotate relative to the roller 10. The inner end of the roller 10 is fixed to the extension 7 at the second end of the inner cylinder window pad 5. Figure 7 As shown, the liner 9 is provided with an annular groove 12, which opens to one side of the extension 7 at the second end of the inner cylinder window gasket 5. The outer end of the roller 10 and the second ball bearing 11 are located in the annular groove 12 of the liner 9.

[0055] The number of turns of the annular groove 12 of the liner 9 is the same as the number of turns of the roller 10, combined with Figure 3 ,4 As shown in Figures 7 and 8, the number of turns of the annular groove 12 of the liner 9 and the number of turns of the roller 10 are both 2 turns.

[0056] The liner 9 is in circumferential contact with the observation window 2 of the machine door 1 and remains stationary relative to it. The liner 9 is provided with an annular groove 12. Multiple rollers 10 are evenly arranged around the observation window 2 of the machine door 1. The inner end of the roller 10 is fixed to the extension 7 of the second end of the inner cylinder window pad 5. The outer end of the roller 10 is provided with a second ball bearing 11 that can rotate relative to the roller bearing 10. The second ball bearing 11 and part of the roller bearing 10 extend into the annular groove 12 from the opening of the annular groove 12 of the liner 9. When the extension 7 of the inner cylinder window pad 5 rotates with the inner cylinder 3, it drives the roller bearing 10 to rotate. The arrangement of the second ball bearing 11 realizes the rolling contact between the second ball bearing 11 and the liner 9, reducing friction.

[0057] To prevent the pad 9 from separating from the roller 10, the roller 10 includes an outer end, a connecting part, and an inner end. The diameter of the outer end is larger than that of the connecting part, and the opening size of the annular groove 12 of the pad 9 is smaller than the diameter of the outer end of the roller 10. The outer end of the roller 10 and the part of the connecting part near the outer end are located within the annular groove 12 of the pad 9. The fit between the large-diameter outer end of the roller 10 and the small-sized opening of the annular groove 12 of the pad 9 prevents the pad 9 from separating from the roller 10.

[0058] A second ball bearing seat 17 is provided at the outer end of the roller 10. The second ball bearing seat 17 is recessed, and the second ball 11 is disposed in the recess of the second ball bearing seat 17 with a clearance fit. More than half of the second ball 11 is embedded in the recess of the second ball bearing seat 17, so that the second ball bearing seat 17 can both restrain the second ball 11 from falling out and allow the second ball 11 to rotate within the recess of the second ball bearing seat 17, thereby enabling the second ball 11 to roll in contact with the liner 9 and reducing wear on the liner 9.

[0059] The diameter of the second ball bearing seat 17 is larger than the opening size of the annular groove 12 of the pad 9, thereby preventing the roller 10 from coming out of the opening of the annular groove 12 of the pad 9 and avoiding the separation and detachment of the roller 10 from the pad 9.

[0060] The pad 9 is made of flexible material. The opening of the annular groove 12 of the pad 9 can be opened by external force to insert the outer end of the roller 10 into the annular groove 12 of the pad 9. After the external force is removed, the opening of the annular groove 12 of the pad 9 can return to its original state.

[0061] In order to reduce the frictional loss between the opening side of the annular groove 12 of the pad 9 and the roller 10, a collar 13 that can rotate relative to the roller 10 is provided on the connecting part of the roller 10. The collar 13 makes rolling contact with the opening side of the annular groove 12 of the pad 9.

[0062] Example 4

[0063] This embodiment is an improvement upon embodiment three.

[0064] To further prevent the roller 10 from separating from the pad 9, combined with Figure 5 , 6 As shown, an annular frame 14 is provided on the outer periphery of the collar 13. The diameter of the annular frame 14 is larger than the opening size of the annular groove 12 of the pad 9. The annular frame 14 is located inside the annular groove 12 of the pad 9. In this way, the annular frame 14 is blocked by the opening side of the annular groove 12 of the pad 9, preventing the roller 10 from coming out of the annular groove 12 of the pad 9. Since the annular frame 14 is provided on the outer periphery of the collar 13, and the collar 13 is in contact with the opening side of the annular groove 12 of the pad 9, the distance between the annular frame 14 and the opening side of the annular groove 12 of the pad 9 is closer than the distance between the outer end of the roller 10 and the opening side of the annular groove 12 of the pad 9. Therefore, the arrangement of the annular frame 14 makes the relative movement of the roller 10 and the pad 9 more stable, the relative movement of the roller 10 and the pad 9 in the axial direction of the roller 10 is smaller, and the operation of both is smoother.

[0065] In order to reduce the frictional wear between the ring frame 14 and the opening side of the annular groove 12 of the liner 9, a third ball bearing 15 is provided on the ring frame 14.

[0066] The annular frame 14 has multiple recesses on one side of the opening of the annular groove 12 of the liner 9. The multiple recesses are evenly arranged around the central axis of the annular frame 14, and the opening of the recesses faces the opening of the annular groove 12 of the liner 9. A third ball bearing 15 is provided in each recess.

[0067] More than half of the third ball bearing 15 is embedded in the recess of the annular frame 14, allowing the third ball bearing 15 to rotate relative to the annular frame 14. By providing a recess on the annular frame 14, the third ball bearing 15 is in clearance fit with the recess wall, thus the recess of the annular frame 14 can both restrain the third ball bearing 15 from falling out and allow the third ball bearing 15 to rotate within the recess of the annular frame 14. This allows the third ball bearing 15 to roll into contact with the opening side of the annular groove 12 of the liner 9. Furthermore, since the third ball bearing 15 protrudes from the annular frame 14, friction between the inner annular frame 14 and the opening side of the annular groove 12 of the liner 9 can be reduced or avoided.

[0068] The first end of the inner cylinder window gasket 5 is fixedly or slidably connected to the opening of the inner cylinder 3.

[0069] When the first end of the inner cylinder window gasket 5 is fixedly connected to the opening of the inner cylinder 3, the inner cylinder window gasket 5 rotates with the inner cylinder 3. When the first end of the inner cylinder window gasket 5 is slidably connected to the opening of the inner cylinder 3, the inner cylinder window gasket 5 may not rotate with the inner cylinder 3, but may rotate with the inner cylinder 3 under certain circumstances.

[0070] To facilitate observation of the washing process of clothes in the inner drum 3 of the washing machine, the inner drum window gasket 5 is a transparent window gasket.

[0071] The present invention also proposes a garment processing device, including the aforementioned door limiting device.

[0072] By installing the aforementioned door limiting device on the garment handling equipment, it is possible to prevent the laundry items in the inner drum 3 from getting stuck in the angled gap between the outer drum window gasket 6 and the observation window 2 of the machine door 1 during washing, and to minimize the friction between the door limiting device and the observation window 2 of the machine door 1.

[0073] This invention relates to a door limiting device and a garment handling equipment. The door limiting device includes an inner cylinder window pad, with a first end connected to the opening of the inner cylinder and a second end abutting against the inner convex surface of the machine door's observation window. By setting the inner cylinder window pad and utilizing the structure where the first end of the inner cylinder window pad is connected to the opening of the inner cylinder and the second end of the inner cylinder window pad abuts against the inner convex surface of the machine door's observation window, the inner cylinder window pad seals the angled gap between the outer cylinder window pad and the machine door's observation window, thereby preventing garments from getting stuck in this angled gap.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention.
