Description

Technical Field

[0001] This utility model relates to the field of washing machine technology, specifically to a washing machine with an ozone sterilization structure. Background Technology

[0002] Washing machines mainly use two types of washing methods: wet washing and waterless washing. Wet washing uses the combined action of water flow and detergent to clean clothes. Waterless washing (such as air washing and dry cleaning) is used to care for valuable clothes that cannot be washed with water. It mainly uses special detergents (organic solvents such as tetrachloroethylene and gasoline) and airflow to remove stains and odors.

[0003] In water washing, the inner and outer drums, as well as the washed clothes, are in a humid environment, making them prone to the growth of bacteria, mold, and other microorganisms. In waterless washing, the specialized detergents and airflow themselves cannot effectively kill these microorganisms.

[0004] To overcome the aforementioned problems, washing machines with sterilization functions have emerged in existing technologies. Among them, ozone sterilization technology is one of the widely used sterilization methods. Ozone is a strong oxidant that can rapidly destroy the cell structure of microorganisms such as bacteria and viruses, thereby achieving the purpose of sterilization, disinfection, and deodorization.

[0005] However, in existing ozone sterilization washing machines, the ozone outlet of the ozone pipeline is exposed to the internal environment of the washing machine, without being covered or opened according to the different needs of the washing or sterilization program. When ozone sterilization is not needed, the ozone outlet is in an open state, and water vapor and foam during water washing, as well as lint in the airflow during waterless washing, can enter the ozone pipeline, easily causing contamination or blockage, thus reducing the reliability of ozone sterilization.

[0006] Therefore, there is an urgent need in this field for a washing machine ozone sterilization structure that can flexibly open and close the ozone outlet in order to improve the reliability of ozone sterilization. Utility Model Content

[0007] To address the aforementioned shortcomings of existing technologies, this invention proposes a washing machine with an ozone sterilization structure. This invention allows for flexible opening and closing of the ozone outlet, thereby improving the reliability of ozone sterilization.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A washing machine with an ozone sterilization structure includes an outer drum and an inner drum. The inner drum is rotatably connected to the outer drum via a rotating shaft. The inner wall of the inner drum is provided with several lifting ribs. The rotating shaft is a hollow shaft. The bottom of the inner drum is provided with an air distribution chamber. One end of the hollow shaft is connected to the air outlet of an ozone generator via a rotary joint, and the other end of the hollow shaft is connected to the air distribution chamber. The lifting ribs are connected to the air distribution chamber. The surface of the lifting ribs is provided with several first air holes. A cover is provided on the outside of the lifting ribs. The cover is provided with several second air holes. The outside of the inner drum is provided with a driving structure for driving the cover to slide axially. The cover includes a first state and a second state. When the cover is in the first state, the first air holes and the second air holes coincide. When the cover is in the second state, the first air holes and the second air holes are staggered.

[0009] Furthermore, the drive structure includes a bracket, a telescopic component, and a collar. The bracket is located on the top of the inner wall of the outer cylinder, and the telescopic component is provided on the bracket. The output end of the telescopic component is connected to the collar, which is sleeved on the outside of the inner cylinder. The inner cylinder wall is provided with an axial elongated hole, and the cover is provided with an adjusting rod, which is located in the axial elongated hole. All adjusting rods on the cover are connected to a collar.

[0010] Furthermore, the collar is provided with an insertion hole, the adjusting rod is inserted into the insertion hole, a limit nut is threadedly connected to the adjusting rod, and the collar is located between the limit nut and the outer wall of the inner cylinder.

[0011] Furthermore, the cover body is provided with a first insertion part at both axial ends, and a first anti-tilting part is provided at the bottom of the first insertion part. The inner cylinder wall is provided with a first gourd hole. When the first insertion part enters the small end section from the large end section of the first gourd hole, the first anti-tilting part slides in contact with the outer wall of the inner cylinder.

[0012] Furthermore, the bottom of the inner cylinder is provided with a first interface, which is connected to the air distribution chamber. One end of the lifting rib is provided with a second interface, which is sleeved on the first interface. The other end of the lifting rib is connected to the inner cylinder by a fastener.

[0013] Furthermore, the bottom of the lifting rib is provided with a second insertion part, the bottom of the second insertion part is provided with a second anti-tilting part, and the inner cylinder wall is provided with a second gourd hole. When the second insertion part enters the small end section from the large end section of the second gourd hole, the second interface is sleeved on the first interface, and the second anti-tilting part contacts the outer wall of the inner cylinder.

[0014] Furthermore, it also includes a body, inside which are provided the outer cylinder, the inner cylinder and the ozone generator. The ozone generator is located at the bottom of the body, and the air inlet of the ozone generator extends to the outside of the body.

[0015] The beneficial effects of this utility model are: 1. The ozone generator, rotary joint, hollow shaft, air distribution chamber, inner cavity of the lifting ribs, and first air hole constitute the ozone gas path system. By setting an axially sliding cover on the lifting ribs, and setting a second air hole on the cover, and in conjunction with the drive structure, the cover can switch between a first state (first and second air holes coincide, ozone is released) and a second state (first and second air holes are staggered, ozone is turned off). During non-ozone sterilization, it effectively prevents water and detergent from entering the gas path system during washing, and also prevents lint from entering the gas path system during waterless washing. This protects the ozone generator and gas path, improving the reliability and service life of the ozone sterilization system.

[0016] 2. Because a hollow shaft is used as the rotating shaft, and one end of the hollow shaft is connected to the ozone generator through a rotary joint, while the other end is connected to the air distribution chamber at the bottom of the inner drum, ozone is released through the lifting ribs connected to the air distribution chamber and the first air hole on its surface. This combines ozone delivery with the clothing lifting and tumbling function, increasing the contact between ozone and clothing, improving the utilization efficiency and sterilization effect of ozone, and reducing sterilization dead spots.

[0017] 3. The drive structure uses a collar to connect the adjusting rods on all the enclosures, and the collar is driven axially by the telescopic component. This ingenious design allows for synchronous control of the movement of all enclosures through a single drive source, ensuring consistency in the ozone outlet status of all enclosures, while maintaining a simple structure.

[0018] 4. By inserting the adjusting rod into the socket and using the threaded limit nut to restrict the collar between the limit nut and the outer wall of the inner cylinder, a detachable connection between the adjusting rod and the collar is achieved. This not only makes assembly convenient but also facilitates maintenance and replacement of individual covers.

[0019] 5. By setting a first insertion part and a first anti-tilting part at both ends of the axial direction of the cover, and cooperating with the first gourd hole on the inner cylinder wall, when the first insertion part slides from the large end section into the small end section of the first gourd hole, the first anti-tilting part slides in contact with the outer wall of the inner cylinder, preventing the cover from tilting under the action of airflow or vibration, and ensuring its smooth sliding.

[0020] 6. By setting a first interface at the bottom of the inner cylinder and a second interface at one end of the lifting rib, the second interface is fitted onto the first interface, and the other end is fixed to the lifting rib with fasteners. This connection method enables the lifting rib and the inner cylinder to be detachable, facilitating assembly and maintenance.

[0021] 7. A second insertion part and a second anti-tilting part are provided at the bottom of the lifting rib, which mate with the second hoist hole on the inner cylinder wall. During installation, the second insertion part enters the small end section from the large end of the second hoist hole, at which point the second interface fits precisely onto the first interface, while the second anti-tilting part contacts the outer wall of the inner cylinder. This structure enables rapid and accurate positioning of the lifting rib and effectively prevents it from tilting or loosening under stress, thus improving stability. Attached Figure Description

[0024] To better understand this utility model, it will be further described below with reference to the accompanying drawings. It is worth noting that in the description of this utility model, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0025] Example: See Figures 1 to 14 A washing machine with an ozone sterilization structure includes a body 100, an outer drum 200, an inner drum 300, and an ozone generator 600.

[0026] See Figure 1 The main body 100 serves as the support and outer shell of the entire washing machine. The outer drum 200 is installed inside the main body 100. The inner drum 300 is rotatably connected to the outer drum 200 via a pivot. See also Figure 2 The shaft is driven to rotate by a motor and belt drive assembly. See also Figure 1 and Figure 3 The inner wall of the inner cylinder 300 is provided with multiple lifting ribs 500 for lifting and tumbling clothes.

[0027] In this embodiment, the rotating shaft is a hollow shaft 400. See also Figure 7 The inner cylinder 300 has an air distribution chamber 301 at its bottom. (See also...) Figure 4 One end of the hollow shaft 400 is connected to the outlet pipe 602 via a rotary joint 401. The outlet pipe 602 is made of stainless steel and is connected to the outlet end of the ozone generator 600. See also Figure 7 The other end of the hollow shaft 400 is connected to the air distribution chamber 301. The ozone generated by the ozone generator 600 can pass through the outlet pipe 602, the rotary joint 401, and the hollow shaft 400 in sequence, and finally enter the air distribution chamber 301.

[0028] See Figure 12 The lifting rib 500 has a hollow internal structure and is connected to the air distribution cavity 301. Several first air holes 501 are formed on the surface of each lifting rib 500. (See also...) Figure 11 Each lifting rib 500 is further provided with a cover 700 on its outer side, and the cover 700 has several second air holes 701. See Figure 10 A drive structure 800 is provided on the outer side of the inner cylinder 300 to drive all the covers 700 to slide synchronously along the axial direction of the inner cylinder 300.

[0029] The cover 700 has two operating states: a first state and a second state. When the drive structure 800 drives the cover 700 to slide to the first state, see [reference needed]. Figure 11 In the indicated state, the second vent 701 on the cover 700 completely overlaps with the first vent 501 on the lifting rib 500, allowing ozone to be discharged smoothly. When the drive structure 800 drives the cover 700 to slide to the second state, the first vent 501 and the second vent 701 are offset from each other, and the first vent 501 is blocked by the wall of the cover 700, thus closing the ozone release channel.

[0030] To improve the airtightness of the cover 700 in the first state, a sealing gasket can be fixedly installed (e.g., using adhesive) on the inner wall of the cover 700. The sealing gasket has holes corresponding to the positions of the second vent 701 to prevent obstruction of the second vent 701. When the cover 700 covers the surface of the lifting rib 500, the sealing gasket can fill the gap between the surface of the lifting rib 500 and the inner wall of the cover 700, improving the sealing effect.

[0031] In a preferred embodiment, see Figure 10 The drive structure 800 includes a bracket 801, a telescopic member 802, and a collar 803. (See also...) Figure 3 or Figure 5 The bracket 801 is fixedly installed on the top of the inner wall of the outer cylinder 200. See also... Figure 6 The telescopic component 802 (such as an electric actuator or cylinder) is fixedly mounted on the bracket 801. A collar 803 is installed at the output end of the telescopic component 802, and this collar 803 is fitted onto the outside of the inner cylinder 300. See also... Figure 8 An axially elongated hole 302 is formed along the axial direction on the wall of the inner cylinder 300. (See also...) Figure 14 Each cover 700 is equipped with two adjusting rods 702, and the cover 700 and the adjusting rods 702 are an integral structure. See also Figure 6These adjusting rods 702 pass through corresponding axial elongated holes 302, and the ends of all adjusting rods 702 are fixedly assembled with the aforementioned collar 803. When the telescopic component 802 moves, it drives the collar 803 to move axially, and the collar 803 then drives all the covers 700 to slide synchronously along the inner cylinder 300 axially through the adjusting rods 702, realizing the switching between the first state and the second state.

[0032] For ease of assembly and maintenance, see [link / reference] Figure 10 A socket 804 is provided on the collar 803. See also Figure 6 or Figure 7 The end of the adjusting rod 702 is inserted into the insertion hole 804, and a limiting nut 805 (the thread on the adjusting rod 702 is not shown) is threaded onto the adjusting rod 702. The collar 803 is clamped between the limiting nut 805 and the outer wall of the inner cylinder 300 to prevent the cover 700 from detaching from the inner cylinder 300 radially.

[0033] To ensure the cover 700 slides smoothly and does not warp, see Figure 11 or Figure 14 A first insertion portion 703 is provided at both axial ends of the cover 700, and the bottom of the first insertion portion 703 extends outward to form a first anti-tilting portion 704. Accordingly, see... Figure 8 On the inner cylinder 300, corresponding to both ends of each cover 700, a first gourd-shaped hole 303 is provided. During installation, the first insertion part 703 is inserted into the larger end of the first gourd-shaped hole 303 and then slid axially to enter the smaller end. When the first insertion part 703 enters the smaller end, the first anti-tilting part 704 maintains sliding contact with the outer wall of the inner cylinder 300, effectively preventing the cover 700 from tilting. Furthermore, the smaller end of the first gourd-shaped hole 303 has sufficient axial length to accommodate the entire sliding stroke of the adjusting rod 702 within the axially elongated hole 302.

[0034] For instructions on installing the 500 lifting rib, please refer to [link / reference]. Figure 9 A first interface 305 is provided at the bottom of the inner cylinder 300, and this first interface 305 communicates with the air distribution chamber 301. See also Figure 11 A second interface 502 is provided at one axial end of the lifting rib 500. During installation, the second interface 502 is fitted onto the first interface 305, thereby achieving air passage connection. Then, see... Figure 6 At the other end of the lifting rib 500, fasteners such as bolts are used to fix it to the inner cylinder 300 wall.

[0035] To improve airtightness, a sealing ring can be fitted on the outside of the first interface 305. When the second interface 502 is fitted onto the first interface 305, the end face of the second interface 502 presses the sealing ring tightly against the bottom surface of the inner cylinder 300.

[0036] Similarly, to improve the accurate positioning and anti-warping of rib 500, see [link / reference]. Figure 13 A second insertion part 503 is provided at the bottom of the lifting rib 500, and the bottom of the second insertion part 503 extends outward to form a second anti-tilting part 504. See also Figure 8 A second gourd hole 304 is made at a corresponding position on the inner cylinder wall 300. During installation, the second insertion part 503 is inserted into the larger end of the second gourd hole 304 and then slid to the smaller end. At this time, the second interface 502 is sleeved on the first interface 305, and the second anti-tilting part 504 contacts the outer wall of the inner cylinder 300 to prevent the lifting rib 500 from tilting.

[0037] See Figure 2 The ozone generator 600 is preferably installed at the bottom of the body 100 to make full use of space. Its air intake end extends to the outside of the body 100 through the air intake pipe 601 for drawing in air.

[0038] The working principle is as follows: In water-wash or waterless-wash mode, the ozone sterilization mode is turned off. The output end of the telescopic component 802 extends, pushing the collar 803 forward axially. The collar 803 pushes all the covers 700 forward together through the adjusting rod 702, so that the second air hole 701 on the cover 700 is misaligned with the first air hole 501 on the lifting rib 500, so that the cover 700 is in the second state, realizing the closure of the ozone outlet (i.e., the first air hole 501) and preventing water, detergent or lint from flowing back in.

[0039] When ozone sterilization is required, the water wash mode or waterless wash mode is turned off. The output end of the telescopic component 802 retracts, pulling the collar 803 axially backward. The collar 803, through the adjusting rod 702, drives all the covers 700 to move backward together, causing the covers 700 to switch to the first state (first air hole 501 and second air hole 701 overlap), at which point the ozone outlet opens. Ozone enters the lifting rib 500 through the air outlet pipe 602, rotary joint 401, hollow shaft 400, and air distribution chamber 301, and is finally evenly released into the inner drum 300 through the overlapping first air hole 501 and second air hole 701 to sterilize the clothes. During the ozone sterilization process, the rotation of the inner drum 300 causes the clothes to be continuously lifted, tumbled, and dropped by the lifting rib 500. Under this mechanical action, the clothes become fluffy, the fiber gaps widen, and the ozone gas can penetrate the clothing layer, improving the sterilization effect.

[0040] Based on the above working principle, it can be seen that this embodiment has the following advantages: First, in this embodiment, the ozone generator 600, rotary joint 401, hollow shaft 400, air distribution chamber 301, inner cavity of lifting rib 500, and first air hole 501 constitute the ozone gas path system. By providing an axially sliding cover 700 on the lifting rib 500, and a second air hole 701 on the cover 700, and in conjunction with the drive structure 800, the cover 700 can switch between a first state (first air hole 501 and second air hole 701 overlap, ozone is released) and a second state (first air hole 501 and second air hole 701 are staggered, ozone is turned off). During non-ozone sterilization, this effectively prevents water and detergent from entering the gas path system during washing, and also prevents lint from entering the gas path system during waterless washing. This protects the ozone generator 600 and the gas path, improving the reliability and service life of the ozone sterilization system.

[0041] Secondly, because a hollow shaft 400 is used as the rotating shaft, and one end of the hollow shaft 400 is connected to the ozone generator 600 through a rotary joint 401, and the other end is connected to the air distribution chamber 301 at the bottom of the inner cylinder 300, ozone is released through the lifting rib 500 connected to the air distribution chamber 301 and the first air hole 501 on its surface. This can combine ozone delivery with the clothing lifting and tumbling function, increase the contact degree between ozone and clothing, improve the utilization efficiency and sterilization effect of ozone, and reduce sterilization dead corners.

[0042] Third, the drive structure 800 connects the adjusting rods 702 on all the covers 700 using a collar 803, and allows the collar 803 to move axially driven by the telescopic component 802. This ingenious design allows for synchronous control of the movement of all covers 700 through a single drive source, ensuring consistency in the ozone outlet status of all covers, while maintaining a simple structure.

[0043] Fourth, by inserting the adjusting rod 702 into the insertion hole 804 and using the threaded limit nut 805 to restrict the collar 803 between the limit nut 805 and the outer wall of the inner cylinder 300, the adjusting rod 702 and the collar 803 are detachably connected, which not only makes assembly convenient, but also facilitates maintenance and replacement of individual covers 700.

[0044] Fifth, by providing a first insertion part 703 and a first anti-tilting part 704 at both axial ends of the cover 700, and engaging with the first gourd hole 303 on the inner cylinder 300 wall, when the first insertion part 703 slides from the large end of the first gourd hole 303 into the small end, the first anti-tilting part 704 slides against the outer wall of the inner cylinder 300, preventing the cover 700 from tilting under the action of airflow or vibration, and ensuring its smooth sliding.

[0045] Sixth, by setting a first interface 305 at the bottom of the inner cylinder 300 and a second interface 502 at one end of the lifting rib 500, the second interface 502 is sleeved onto the first interface 305, and the other end is fixed to the lifting rib 500 with fasteners. This connection method realizes the detachable design of the lifting rib 500 and the inner cylinder 300, which facilitates assembly and maintenance.

[0046] Seventh, a second insertion part 503 and a second anti-tilting part 504 are provided at the bottom of the lifting rib 500, and these parts mate with the second gourd hole 304 on the inner cylinder 300 wall. During installation, the second insertion part 503 enters the small end of the second gourd hole 304 from the large end, at which point the second interface 502 fits precisely onto the first interface 305, while the second anti-tilting part 504 contacts the outer wall of the inner cylinder 300. This structure enables rapid and accurate positioning of the lifting rib 500 and effectively prevents the lifting rib 500 from tilting or loosening under stress, thus improving stability.

[0047] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
