In addition, the terms "first", "second" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0030] In the description of the embodiments of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "arrangement", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, it can be directly connected, or indirectly connected through an intermediate medium, it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0031] Please refer to Figures 1-5 The preferred embodiment of the present application provides a washing machine disinfection device, the device comprises a sealed shell 1, a control panel 26 and an elastic fixing frame 2 arranged in the sealed shell 1, an ozone generator 3, an air pump 4 and a battery 5 fixed in the elastic fixing frame 2, the ozone generator 3, the air pump 4 and the battery 5 are electrically connected to the control panel 26. Among them, the sealed shell 1 has good sealing property, which can prevent water from entering the air pump 4 and the ozone generator 3, and the top surface is provided with an air inlet 8 and an air outlet 9 for air exchange inside and outside, the air inlet 8 and the air outlet 9 can be ventilated with the outside when the air pump 4 works; the elastic fixing frame 2 has elasticity, which can stably fix the ozone generator 3, the air pump 4 and the battery 5, and prevent them from falling off when rolling or being impacted; the ozone generator 3 can convert oxygen in the air into ozone molecules when powered on; the air pump 4 can exchange air inside and outside the sealed shell 1, on the one hand to provide air for the ozone generator 3, and on the other hand to deliver ozone molecules outside the sealed shell 1; the control panel 26 can control the switch of the air pump 4 and the ozone generator 3, which can make the air pump 4 and the ozone generator 3 work only in the waterless state; the battery provides power for the ozone generator and the air pump.

[0032] The laundry sterilization device has the advantages that the sealing shell 1 is arranged, so that water 5 cannot enter the ozone generator 3 and the air pump 4; the elastic fixing frame 2 is arranged, so that the ozone generator 3, the air pump 4 and the battery 5 can adapt to the tumbling environment in the laundry and cannot be loosened; the control panel 26 is arranged, so that the air pump 4 and the ozone generator 3 can work only in the condition of no water; the ozone generator 3 and the air pump 4 are arranged, so that the ozone generator 3 can generate ozone molecules, the ozone molecules are delivered to the outside by the air pump 4, the ozone molecules can sterilize and disinfect the inside of the laundry and the clothes, the ozone molecules are very easy to decompose, the product after decomposition is oxygen, and therefore the ozone molecules do not have any influence on the human body,

[0033] Compared with disinfectant, the ozone is more healthy and environment-friendly.

[0034] Compared with disinfectant, the ozone is more healthy and environment-friendly.

[0035] The air pump 4 can be arranged on the upstream or downstream of the air path for air exchange between the inside and the outside, the air pump 4 can suck the air outside the sealing shell 1 and then deliver the ozone in the sealing shell 1, but because of the strong oxidizing effect of the ozone, when the air pump 4 is arranged on the downstream of the air path for air exchange between the inside and the outside, the ozone molecules can pass through the air pump 4, the strong oxidizing effect of the ozone can accelerate the aging of the air pump 4 and affect the service life of the air pump 4.

[0036] Therefore, in a preferred embodiment, the air pump 4 is arranged on the upstream of the air path for air exchange between the inside and the outside, that is, the air in the inside and the outside is first passed through the air pump 4 and then passed through the ozone generator 3, the air is blown to the ozone generator 3 by the air pump 4, therefore,

[0037] The ozone molecules generated by the ozone generator 3 cannot be blown back to the air pump 4, so that the influence of the ozone on the air pump 4 is reduced. Even if the ozone molecules are sucked into the sealing shell 1 after being delivered to the outside of the sealing shell 1, because the ozone molecules are easy to decompose, the influence of the ozone molecules on the air pump 4 is very small.

[0038] When the laundry sterilization device is used, because the device is in a water environment, when water seeps into the inside of the device, a circuit short circuit can be caused. In order to improve the sealing performance of the device, in a preferred embodiment, as shown in FIG. 6,

[0039] as shown in FIG. 6, Figure 1 Figure 9 the sealing shell 1 includes a shell body 6 and a cover body 7 arranged on the shell body 6, the shell body 6 can be a cylindrical or square cylindrical structure with one end sealed,

[0040] ​It can also be any structure with one open end and an accommodating cavity inside. In this embodiment, the shell 6 is a square cylindrical structure with one closed end, and its edges are rounded so as not to damage clothes. The cover 7 is structured to fit the opening of the shell 6, and it can fully cover the opening of the shell 6, as shown in Figure 2 、 Figure 3 、 Figure 9 The cover 7 is provided with an air inlet 8 and an air outlet 9, and the bottom of the cover 7 is provided with a downwardly extending cover rim 10 near the edge. The size of the cover rim 10 is adapted to the shell 6, and at least one ring groove 11 is provided on the outer side wall of the cover rim 10. The ring groove 11 is provided with a first sealing ring 12. When the cover 7 is placed on the shell 6, the cover rim 10 is inserted into the shell 6, the side wall of the cover rim 10 abuts against the inner side wall of the shell 6, and the first sealing ring 12 deforms to abut against the inner side wall of the shell 6, thereby preventing water from entering the shell 6 from the connection between the cover 7 and the shell 6, and achieving good waterproof performance.

[0041] To make the connection between the cover 7 and the shell 6 more stable, threaded holes are provided on the four corners of the cover 7, and connecting columns 13 are provided on the shell 6 corresponding to the threaded holes, as shown in Figure 9 The connecting columns 13 are also provided with threaded holes, so that the cover 7 and the shell 6 can be more stably connected by screws or bolts.

[0042] In a preferred embodiment, as shown in Figure 5 The air pump 4 is connected with a first air inlet pipe 14 and a first air outlet pipe 15, the top end of the ozone generator 3 is provided with a second air inlet pipe 16, the bottom end of the ozone generator 3 is provided with a second air outlet pipe 17, and the elastic fixing frame 2 is further provided with an exhaust passage 20. As shown in Figure 5 、 Figure 8 The air inlet 8 is connected with the first air inlet pipe 14, the first air outlet pipe 15 is connected with the second air inlet pipe 16 through a first connecting pipe 18, the second air outlet pipe 17 is connected with the exhaust passage 20 through a third connecting pipe 21, and the top of the exhaust passage 20 is connected with the air outlet 9 through a second connecting pipe 19. In the specific implementation process, under the action of the air pump 4, air outside the sealed shell 1 (i.e., air in the washing machine) is sucked into the sealed shell 1 through the air inlet 8, and then enters the ozone generator 3 through the first air outlet pipe 15, the first connecting pipe 18, and the second air inlet pipe 16. Under the action of the ozone generator 3, ozone molecules are generated, and then are discharged through the second air outlet pipe 17, the third connecting pipe 21, the exhaust passage 20, and the second connecting pipe 19, and finally are discharged through the air outlet 9.

[0043] However, since the disinfection device is used in a washing machine, the constant tumbling of clothes during operation can loosen the internal structure of the disinfection device, causing it to malfunction. Therefore, in a preferred embodiment, such as... Figure 2 As shown, the elastic fixing frame 2 is a square columnar structure adapted to the internal structure of the housing 6. Its four side walls abut against the inner side walls of the housing 6, and it is provided with clearance angles at the positions of the corresponding connecting columns 13 to ensure elasticity.

[0044] While ensuring full contact between the sidewall of the fixing bracket 2 and the inner sidewall of the housing 6, the corresponding connecting column 13 at position 5 should also be in full contact for better support. The elastic fixing bracket 2 contains an ozone chamber 22 for accommodating the ozone generator 3, an air pump chamber 23 for accommodating the air pump 4, and a battery chamber 24 for accommodating the battery 5. The bottom of the elastic fixing bracket 2 has a bottom cover 25 detachably connected to it. The ozone chamber 22, air pump chamber 23, and battery chamber 24 all open downwards. During installation, the…

[0045] The ozone generator 3, air pump 4, and battery 5 are all inserted into their respective chambers from below the elastic mounting bracket 2, and then sealed by the bottom cover 25, thus stably fixing the ozone generator 3, air pump 4, and battery 5 onto the elastic mounting bracket 2. The control board 26 is fixed to the bottom cover 25 and is electrically connected to the ozone generator 3, air pump 4, and battery 5, respectively. The control board 26 can control the switching on and off of the ozone generator 3 and air pump 4.

[0046] By setting up the elastic fixing bracket 2, the ozone generator 3, air pump 4 and battery 5 can be stably fixed in the sealed housing 1. Even in the constantly tumbling environment, the ozone generator 3, air pump 4 and battery 5 will not loosen at will, thus ensuring the normal disinfection process.

[0047] To reduce the impact of tumbling impacts on the ozone generator 3, air pump 4, and battery 5, in a preferred embodiment, the elastic fixing frame 2 is made of silicone, rubber, or other materials with good elasticity.

[0048] It is made of high-performance polymer material, and has a hollow structure 27 with a buffering effect on the side wall of the elastic fixing frame 2, such as... Figure 2 As shown, the hollow structure 27 includes a through-hole that extends vertically. When the outer casing is impacted, the wall of the through-hole deforms to eliminate the impact force on the ozone generator 3, air pump 4, and battery 5 mounted on the elastic bracket 2. Simultaneously, to enhance the supporting effect of the through-hole, reinforcing ribs are also provided inside the through-hole.

[0049] The elastic hole interval is a plurality of small elastic holes, which can be the same in structure and size, different in structure and size, or in a special symmetrical structure. Preferably, the reinforcing rib is arranged at the middle position of the side wall of the elastic fixing frame 2, because the middle part of the side wall of the elastic fixing frame 2 is closer to the positions of the functional components, and through the arrangement of the reinforcing rib, the functional components can be better supported, and the anti-collision ability can be improved.

[0050] In addition, in order to further reduce the impact on the internal structure of the shell 6, the sealing shell 1 is further sleeved with an anti-collision sleeve 28, as shown in Figure 2 、 Figure 3 The height of the anti-collision sleeve 28 is higher than that of the sealing shell 1, and when the sealing shell 1 is placed in the anti-collision sleeve 28, the top surface of the sealing shell 1 is lower than the top surface of the anti-collision sleeve 28. The anti-collision sleeve 28 is made of soft elastic material such as rubber and silica gel, and is provided with an inner side wall and an outer side wall. The height of the inner side wall is greater than that of the outer side wall, and the structure of the outer side wall being lower and the inner side wall being higher is formed at both ends of the anti-collision sleeve 28. The anti-collision sleeve 28 is open at the upper end and is provided with a grid bottom structure 29 at the bottom, so that the shell can be protected from the side and the bottom. The side wall of the anti-collision sleeve 28 is a cavity partition wall structure 30 provided with a cavity, which has a good buffering effect and can reduce the impact of the impact force on the internal structure, so as to better protect the sealing shell and the structural components arranged in the sealing shell.

[0051] However, the sterilization device for washing machines with the above structure, if a conventional air pipe is used to connect the internal and external air exchange channels, in the process of use, the connection pipes of the channels are easy to loosen due to rolling. Once loosened, not only is it easy to cause water leakage and short circuit, but also it is easy to cause air channel confusion, so that ozone cannot be generated or the generated ozone cannot be transported outside the shell. In a preferred embodiment, as shown in Figure 2 The top of the elastic fixing frame 2 is provided with a cover head 31, and the cover head 31 is provided with a plurality of fixing holes 32. The elastic fixing frame 2 is provided with a plurality of threaded holes corresponding to the positions of the fixing holes 32, and the two can be connected through screws. As shown in Figure 4As shown, the cover head 31 is provided with an air inlet hole 33 and an air outlet hole 34 at positions corresponding to the air inlet 8 and the air outlet 9, and the bottom of the cover head 31 is provided with a first air guide hole 35. The cover head 31 is internally provided with an air guide groove 36, and the first connecting pipe 18 and the second connecting pipe 19 are embedded in the cover head 31. The air guide groove 36 is connected to the air inlet hole 33 and the first air guide hole 35. The first air inlet pipe 14 extends into the first air guide hole and is connected to the air inlet hole through the air guide groove. The first connecting pipe 18 has a U-shaped structure, and the two ends of the first connecting pipe 18 are respectively provided with a first pipe joint 37 and a second pipe joint 38 which extend downward to the bottom surface of the cover head 31. The second connecting pipe 19 is provided with an upper pipe head 39 which extends upward and an lower pipe head 40 which extends downward to the bottom surface of the cover head 31. The upper pipe head 39 is connected to the air outlet hole 34. Since the first connecting pipe 18 and the second connecting pipe 19 are embedded in the cover head 31, the first connecting pipe 18 and the second connecting pipe 19 are not easy to be loosened even in a constantly rolling use environment.

[0052] In a preferred embodiment, as shown in Figure 3 As shown, the cover body 7 is provided with a downwardly extending annular protrusion 41 at positions corresponding to the air inlet 8 and the air outlet 9. The height of the annular protrusion 41 is equal to the distance from the cover body 7 to the cover head 31. When the cover body 7 is placed on the shell 6, the bottom surface of the annular protrusion 41 abuts against the upper surface of the cover head 31. In order to prevent water from leaking into the shell 6 from the position where the annular protrusion 41 contacts the cover body 7, the annular protrusion 41 is further provided with a second sealing ring 42. The outer diameter of the second sealing ring 42 is slightly larger than the inner diameter of the annular protrusion 41, forming an interference fit relationship. Therefore, water is prevented from entering the shell 6 from the position where the annular protrusion 41 contacts the cover head 31, and a better waterproof effect is achieved.

[0053] It should be noted that the first sealing ring 12 and the second sealing ring 42 are both made of elastic materials, such as rubber or silicone, and have good sealing effect.

[0054] However, the above-mentioned cover head 31 can make the air path connection structure fixed and stable, but the production difficulty is large, and the first connecting pipe 18 and the second connecting pipe 19 need to be arranged in the cover head 31 during blow molding. In view of this, in a preferred embodiment, as shown in Figure 4 , Figure 6 As shown, the cover head 31 is composed of a plurality of layers of stacked panels 43, a bottom plate 49, an air path plate and a partition plate. Specifically, the cover head 31 includes the panels 43, the first partition plate 44, the first air path plate 45, the second partition plate 46, the second air path plate 47, the third partition plate 48 and the bottom plate 49 which are sequentially stacked from top to bottom. The panels 43, the first partition plate 44, the first air path plate 45, the second partition plate 46, the second air path plate 47, the third partition plate 48 and the bottom plate 49 are all provided with fixing holes 32.

[0055] The panel 43 is provided with an air inlet hole 33 and an air outlet hole 34 at positions corresponding to the air inlet 8 and the air outlet 9, respectively, as shown in Figure 4 、 Figure 6 The air inlet hole 33 is used for air input, and the air outlet hole 34 is used for outputting ozone molecules outside the sealed shell 1.

[0056] The first partition plate 44 is arranged below the panel 43, as shown in Figure 4 、 Figure 6 The first partition plate 44 is arranged below the panel 43, as shown in Figure 4 、 Figure 6 The first partition plate 44 is arranged below the panel 43, as shown in

[0057] The first gas path plate 45 is provided with a first mounting groove 52 for fixing the first connecting pipe 18, as shown in Figure 4 、 Figure 6 The size of the first mounting groove 52 is matched with the size of the first connecting pipe 18. The second partition plate 46, the second gas path plate 47, the third partition plate 48, and the bottom plate 49 are provided with a first avoiding hole 53 for passing the first pipe joint 37 and a second avoiding hole 54 for passing the second pipe joint 38 at positions corresponding to both ends of the first mounting groove 52.

[0058] In a preferred embodiment, the second gas path plate 47 is further provided with a second mounting groove 55 for fixing the second connecting pipe 19, as shown in Figure 4 、 Figure 6 The shape and size of the second mounting groove 55 are matched with the second connecting pipe 19. The first gas path plate 45 and the second partition plate 46 are provided with a third avoiding hole 56 for passing the upper pipe joint 39 at a position corresponding to the second elastic valve piece 51. The third partition plate 48 and the bottom plate 49 are provided with a fourth avoiding hole 57 for passing the lower pipe joint 40.

[0059] The first gas path plate 45 and the second partition plate 46 are provided with a second air guide hole 58 at a position corresponding to the first elastic valve piece 50, as shown in Figure 6As shown, the third partition plate 48 is provided with a third air guide hole 59 at a position corresponding to the first air guide hole 35, the second air path plate 47 is provided with an air guide groove 36 communicating the second air guide hole 58 and the third air guide hole 59, the air guide groove is enclosed with the second partition plate 46 and the third partition plate 48 to form an air passage, and the air inlet hole 33, the second air guide hole 58, the air guide groove, the third air guide hole 59 and the first air guide hole 35 are sequentially communicated from top to bottom to form an air guide channel, and the opening and closing of the air guide channel is controlled by the first elastic valve plate 50. The air guide groove 36 is used to communicate the air inlet hole 33 and the first air guide hole 35 which are not in the same vertical position, which on the one hand can lengthen the distance between the air pump 4 and the air inlet hole 33 to prevent water from entering the air pump 4, and on the other hand can set the air inlet hole 33 at a position close to the air outlet hole 34, so that the probe 64 for sensing water is set at a position close to the air inlet hole 33 and the air outlet hole 34 to make the sensing of water more accurate.

[0060] The cover head 31 with the above structure can not only stably fix the first connecting pipe 18 and the second connecting pipe 19 to one end of the elastic fixing frame 2, and make the connection of the first connecting pipe 18 with the first air outlet pipe 15 and the second air inlet pipe 16 and the connection of the second connecting pipe 19 with the exhaust passage 20 and the air outlet 9 more stable, but also make the preparation of the cover head 31 simpler and easier to realize. When assembling, the first connecting pipe 18 and the second connecting pipe 19 are fixed in the first mounting groove 52 and the second mounting groove 55 respectively, and then the plates are sequentially connected from top to bottom or from bottom to top to assemble the cover head 31, and then the cover head 31 is fixed in the elastic fixing frame 2 by screws, so that the installation is completed and very convenient.

[0061] In a preferred embodiment, as shown in Figure 6 As shown, the second partition plate 46 is provided with a pipe sleeve 60 at a position corresponding to the first avoiding hole 53 and the second avoiding hole 54, and the third partition plate 48 is provided with a pipe sleeve 60 at a position corresponding to the fourth avoiding hole 57 and the first air guide hole 35, and the inner diameter of the pipe sleeve 60 is matched with the outer diameter of the pipe joint or pipe head inserted therein, which can make the fixation of the first connecting pipe 18 and the second connecting pipe 19 more stable.

[0062] In a preferred embodiment, as shown in Figure 7As shown, the first elastic valve sheet 50 and the second elastic valve sheet 51 each comprise an arc-shaped elastic sheet 61 and a plurality of air-permeable holes 62 arranged on the arc-shaped elastic sheet 61 in a circumferential direction; the diameter of the first elastic valve sheet 50 is greater than that of the air inlet hole 33, and the arc-shaped elastic sheet 61 of the first elastic valve sheet 50 abuts against the air inlet hole 33; the diameter of the second elastic valve sheet 51 is greater than that of the third avoiding hole 56 on the first air passage plate 45, and the second elastic valve sheet 51 abuts against the third avoiding hole 56 on the first air passage plate 45. Since the diameter of the arc-shaped elastic sheet 61 is greater than that of the air inlet hole 33, the arc-shaped elastic sheet 61 abuts upward against the air inlet hole 33 when it is not subjected to external force, and only when the air pump 4 is working, the arc-shaped elastic sheet 61 will be deformed downward due to the negative pressure, so that the air inlet hole 33 is communicated with the air guide channel 36 and the first air inlet pipe 14. The working principle of the second elastic valve sheet 51 is the same as that of the first elastic valve sheet 50, except that the second elastic valve sheet 51 is concave downward, and the second elastic valve sheet 51 is located at the output end of the air pump 4, so that the second elastic valve sheet 51 is deformed upward when the air pump 4 is working, so that the upper pipe head 39 is communicated with the air outlet hole 34, and the second elastic valve sheet 51 seals the third avoiding hole 56 on the first air passage plate 45 when the air pump 4 stops working, so as to prevent water from entering the ozone generator 3 and the air pump 4 through the air outlet hole 34. Therefore, the first elastic valve sheet 50 and the second elastic valve sheet 51 can seal the air inlet hole 33 and the air outlet hole 34 when the air pump 4 stops working, so as to prevent water from entering, and the first elastic valve sheet 50 and the second elastic valve sheet 51 can respectively communicate the air inlet hole 33 and the air outlet hole 34 when the air pump 4 is working, so that the air inside and outside is exchanged.

[0063] In order to improve the sealing performance, as shown in Figure 6 As shown, the bottom surface of the air inlet hole 33 and the top surface of the third avoiding hole 56 on the first air passage plate 45 are respectively provided with arc-shaped notches 63 adapted to the arc-shaped elastic sheet 61, so that the first elastic valve sheet 50 and the second elastic valve sheet 51 can better adhere to the air inlet hole 33 or the third avoiding hole 56 when they are not subjected to external force, and water can be better prevented from entering the air pump 4.

[0064] The above-mentioned structure of the washing machine disinfecting device can only work in the condition of no water. In order to know whether there is water at the air inlet 8 and the air outlet 9, in a preferred embodiment, the cover 7 is provided with two probes 64, as shown in Figure 1 As shown, the two probes 64 are electrically connected with the control panel 26. When the device is in the water state, the two probes 64 can form a continuous circuit, and when the device is in the no-water state, the circuit in which the two probes 64 are located is in an open state. The control panel 26 can determine whether there is water according to the connection state of the circuit in which the two probes 64 are located. When there is no water, i.e. the circuit in which the two probes 64 are located is open, the air pump 4 and the ozone generator 3 are started to work, and when there is water, i.e. the circuit in which the two probes 64 are located is closed, the air pump 4 and the ozone generator 3 are stopped to work. Therefore, through the two probes 64, the control panel 26 can better control the on-off of the air pump 4 and the ozone generator 3, so as to avoid the air pump 4 and the ozone generator 3 working in the water state.

[0065] Preferably, two said probes 64 are arranged near the air inlet 8 and the air outlet 9, and more preferably, two said probes 64 are symmetrically arranged between the air inlet 8 and the air outlet 9, which can more accurately determine whether there is water.

[0066] In use, the washing machine disinfecting device is turned on and put into the washing machine. When the washing machine is filled with water, the probe 64 senses water, and the control panel 26 stops the air pump 4 from working. The first elastic valve 50 and the second elastic valve 51 seal the air inlet hole 33 and the air outlet hole 34, so that water cannot enter the air pump 4 and the ozone generator 3. The washing machine operates, and the disinfecting device rolls with the clothes, which can increase the friction between the clothes and improve the cleaning efficiency. When the washing machine is dehydrated, if the probe 64 does not sense water, the control panel 26 will start the air pump 4 and the ozone generator 3 to work, and ozone is transported into the washing machine to sterilize and disinfect the clothes. When the washing machine is filled with water again, as soon as the probe 64 senses water, the control panel 26 will immediately turn off the air pump 4 and the ozone generator 3. This cycle continues until the washing is completed.

[0067] In addition, the control panel can also set the working time of the air pump and the ozone generator to achieve the purpose of setting the disinfection time.

[0068] It can be understood that, for those skilled in the art, equivalent replacements or changes can be made according to the technical solutions and inventive concepts of the present application, and all such changes or replacements shall belong to the protection scope of the appended claims of the present application.
