[0031] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0032] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "inner," and "outer," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] Example 1: Figures 1 to 4 As shown, a multifunctional washing machine includes a washing machine body 1, an outer barrel 2 and an inner barrel 3. The outer barrel 2 is arranged in the washing machine body 1, and the inner barrel 3 is rotatably arranged in the outer barrel 2. The bottom of the outer barrel 2 is provided with a first heating element 4 and a connecting hole 21. The inner bottom surface of the washing machine body 1 is provided with an ozone generator 5. The air outlet of the ozone generator 5 is connected to the connecting hole 21 through an air guide pipe 51. A one-way valve (not shown in the figure) is provided on the air guide pipe 51. The ozone produced by the ozone generator 5 is injected into the outer barrel 2 through the air guide pipe 51.

[0034] By arranging the first heating element 4 and the ozone generator 5 in the washing machine, the washing machine has both high-temperature steaming and ozone sterilization functions. The user can choose the appropriate sterilization method according to the material of the clothes being washed, and the applicability is good.

[0035] Example 2: Figure 2 、 Figure 3 、 Figures 5 to 7 As shown, the rest of the parts are the same as those in Example 1, except that a mounting cylinder 22 is fixedly provided at the bottom of the outer barrel 2, the upper end of the mounting cylinder 22 is connected to the interior of the outer barrel 2, the first heating element 4 is arranged in the mounting cylinder 22, and the lower end of the first heating element 4 is connected to a mounting plate 41, the mounting plate 41 covers the lower end of the mounting cylinder 22 and cooperates with the lower end of the mounting cylinder 22 to form a waterproof seal, and a detachable end cover 23 is provided at the lower end of the mounting cylinder 22, and the upper end of the end cover 23 abuts against the lower end of the mounting plate 41, so the installation is relatively simple, and it is easy to open the mounting cylinder 22 to remove the first heating element 4, and the maintenance is also relatively simple, which is conducive to controlling production costs; in addition, the installation of the first heating element 4 does not occupy the original internal space of the outer barrel 2, which can effectively avoid the first heating element 4 from contacting with the inner barrel 3, and has better safety.

[0036] In this embodiment, a sealing ring 6 is provided at the lower end of the installation tube 22 , and the lower end of the installation tube 22 cooperates with the upper end of the installation plate 41 to clamp the sealing ring 6 to achieve a waterproof sealing effect.

[0037] In this embodiment, the sealing ring 6 includes an elastic ring 61, the outer ring of which is raised upward to form an outer convex ring 62. The outer convex ring 62 is sleeved on the outer surface of the mounting tube 22, and the inner ring of the elastic ring 61 is raised upward to form an inner convex ring 63. The inner convex ring 63 abuts the inner side surface of the mounting tube 22, and a gap is left between the inner convex ring 63 and the first heating element 4. The provision of the outer convex ring 62 and the inner convex ring 63 can increase the contact area between the sealing ring 6 and the mounting tube 22, which helps to improve the waterproof sealing effect and has better stability. At the same time, a gap is required between the inner convex ring 63 and the first heating element 4 to prevent the heat generated by the first heating element 4 from directly acting on the sealing ring 6 and causing deformation of the sealing ring 6, which ultimately affects the sealing effect, and has better reliability.

[0038] In this embodiment, the bottom of the outer barrel 2 is recessed to form a drainage groove 24. One end of the drainage groove 24 is connected to the mounting tube 22. A drain outlet 25 is provided at the bottom of the drainage groove 24. The heated water flows upward into the outer barrel 2, and the unheated water enters the mounting tube 22 from the side through the drainage groove 24 for heating, thereby realizing water circulation and helping to improve heating efficiency.

[0039] Example 3: Figure 8 As shown, the rest of the parts are the same as those in Example 1, except that a detachable filter screen 7 is provided at the bottom of the outer barrel 2, and the filter screen 7 covers the connecting hole 21. The setting of the filter screen 7 can prevent impurities from entering the air duct 51 through the connecting hole 21, thereby greatly reducing the risk of blockage of the air duct 51.

[0040] In this embodiment, a card slot 26 is provided at the bottom of the outer barrel 2 , the connecting hole 21 is provided at the bottom of the card slot 26 , the filter screen 7 is embedded in the card slot 26 , and the upper end surface of the filter screen 7 is flush with the bottom of the outer barrel 2 .

[0041] Example 4: Figure 5 、 Figures 9 to 12 As shown, the rest of the parts are the same as those in Example 1, except that a cover body 27 is provided on the top of the outer barrel 2, a mounting groove 271 and a cover plate 272 covering the notch of the mounting groove 271 are provided on the cover body 27, an air inlet 2721 is provided on the cover plate 272, an air outlet 2711 is provided at the bottom of the mounting groove 271, a hot air component 8 is provided in the mounting groove 271, and the air outside the cover body 27 flows into the mounting groove 271 through the air inlet 2721, is heated by the hot air component 8, and flows into the outer barrel 2 through the air outlet 2711.

[0042] In this embodiment, the hot air assembly 8 includes an air guide shell 81, a fan 82 and a second heating element 83. The air guide shell 81 has a first connection port 811 and a second connection port 812. The exhaust port of the fan 82 is connected to the first connection port 811, and the second connection port 812 is connected to the air outlet 2711. The second heating element 83 is arranged in the air guide shell 81.

[0043] In this embodiment, the lower end of the air guide shell 81 is provided with a first convex ring 813 surrounding the second connecting port 812, and the first convex ring 813 is inserted into the air outlet 2711. The lower end of the cover body 27 is provided with a second convex ring 273 surrounding the air outlet 2711, and two upper and lower rows of grilles 2731 are provided in the second convex ring 273. The setting of the first convex ring 813 and the second convex ring 273 facilitates alignment and assembly, and improves the stability of the connection between the two; the setting of the grille 2731 can change the path of air flow, prompting the airflow to form a more complex flow pattern at the air outlet 2711, which helps the hot air to fully cover the outer barrel 2 and helps to improve the drying efficiency.

[0044] Conventionally, both the first heating element 4 and the second heating element 83 are PTC heating elements.

[0045] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
