Description

Technical Field

[0001] The present invention belongs to the field of washing machines, and more particularly, relates to a sealing cover and a washing machine for a washing machine. Background Art

[0002] Washing machines have become an essential electrical appliance in people's daily lives. With the enhancement of people's awareness of hygiene, more and more users need to wash different types of clothes separately or wash a small amount of clothes in a timely manner; that is, household consumers are no longer satisfied with the traditional washing method of "washing in one bucket", and put forward a more healthy laundry requirement - "washing multiple times in one machine" and "washing in partitions", requiring a washing machine to effectively distinguish between regular clothes, underwear, and baby clothes for washing to prevent cross-contamination.

[0003] During the washing process of a washing machine, since the inside of the washing machine barrel is sealed, when the washing machine fills with water, as the space decreases, the air is continuously compressed and the air pressure inside the barrel increases continuously. When the pressure inside the barrel is greater than the water inlet pressure, the water flow cannot enter the barrel, which directly affects the washing effect and even makes washing impossible. Moreover, during the washing process of the washing machine, if the pressure inside the barrel cannot be released, dangerous situations such as cracks or even explosions in the washing barrel may occur. To balance the air pressure inside and outside the washing machine, a ventilation channel needs to be provided inside the barrel.

[0004] In view of this, the present invention is specifically proposed. Summary of the Invention

[0049] It should be noted that these drawings and text descriptions are not intended to limit the scope of the concept of the present invention in any way, but to illustrate the concept of the present invention to those skilled in the art by referring to specific embodiments. Detailed Embodiments

[0050] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0051] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "linkage", "contact", and "communication" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] During the washing process of the washing machine, since the inside of the washing machine tub is sealed, when water enters the washing machine, as the space decreases, the air is continuously compressed, and the air pressure inside the tub increases continuously. When the pressure inside the tub is greater than the water inlet pressure, the water flow cannot enter the tub, which directly affects the washing effect and may even prevent washing. Moreover, during the washing process of the washing machine, if the pressure inside the tub cannot be released, dangerous situations such as cracks or even explosions in the washing tub may occur. To solve this problem, this embodiment proposes a sealing cover for the washing machine. The washing machine includes an outer tub 20, as detailed in Figure 1 and Figure 2 , and a partition tub 21 fixedly connected or integrally formed on the bottom wall of the outer tub 20. The annular space between the partition tub 21 and the outer tub 20 forms a first washing area 81, and the inside of the partition tub 21 forms a second washing area 82; the first washing area and the second washing area can wash clothes independently, that is, the washing water in the first washing area 81 and the second washing area 82 cannot flow into each other, avoiding cross-contamination of the washing water.

[0053] The sealing cover includes a first sealing cover 1 and a second sealing cover 2. The first sealing cover is disposed on the top of the outer tub 20 in an openable and closable manner to cover the first washing area 81, or to cover both the first washing area 81 and the second washing area 82 at the same time; the second sealing cover 2 is disposed at the mouth of the partition tub 21 in an openable and closable manner to cover the partition tub 21; a first air-permeable structure is provided on the first sealing cover 1, and the first air-permeable structure communicates the inside of the first washing area 81 with the outside of the first washing area 81; and / or, a second air-permeable structure is provided on the second sealing cover 2, and the second air-permeable structure communicates the inside of the second washing area 82 with the outside of the second washing area 82. In a specific embodiment, the first sealing cover and the second sealing cover can be respectively disposed at the mouth of the outer tub and the mouth of the partition tub in a hinged or detachable manner. During the washing process of the washing machine, since the inside of the washing machine tub is sealed, an air-permeable structure needs to be provided in the washing machine to balance the pressure inside and outside the tub. On the one hand, it can improve the water inlet efficiency during water inlet and the drainage efficiency during drainage. On the other hand, it can prevent the risk of the tub bursting or even exploding due to excessive pressure inside and outside the tub.

[0054] Further optionally, a first handle part is provided on the first sealing cover 1, and the first air-permeable structure is a plurality of first air-permeable holes opened on the first sealing cover 1, and the plurality of first air-permeable holes are hidden under the first handle part;

[0055] and / or, see Figures 5 - 7 , the second sealing cover 2 is provided with a second handle 24, and the second ventilation structure is a plurality of second ventilation holes 26 opened on the second sealing cover 2, and the plurality of second ventilation holes 26 are hidden under the second handle 24. The ventilation holes are provided on the first sealing cover 1 and / or the second sealing cover 2, and the ventilation holes are provided at the lower part of the handle to connect the internal and external environments and balance the pressure inside and outside the barrel. Optionally, a concave structure is formed on the handle, and when the user opens the sealing cover through the handle, the user's device extends into the concave structure to provide a fulcrum for the user, and the ventilation holes are located in the space formed by the concave structure and the top cover. The ventilation structure is simple, can effectively balance the air pressure inside and outside the washing machine, and the structure is concealed, which can ensure that the beauty of the finished product is not affected. Taking the ventilation structure provided on the second sealing cover 2 as an example, a screw hole 27 is provided on the second sealing cover 2, and the second ventilation hole 26 is provided near the screw hole 27, and the second handle 24 is fixed to the second sealing cover 2 by screws or the like. The second ventilation hole 26 is hidden under the handle. The structure of the first vent hole on the first sealing cover 1 is similar to this. In some embodiments, the vent hole is only provided on the first sealing cover 1, or only provided on the second sealing cover 2. In other embodiments, the vent holes are provided on the first sealing cover 1 and the second sealing cover 2 respectively.

[0056] The washing machine further comprises a first laundry treatment part 10, see Figure 1 , Figure 2 , Figure 11 As shown, the first laundry treatment part 10 includes a treatment rack body 11 and a mounting barrel 18. The treatment rack body 11 is a cylindrical structure, rotatably disposed in the first washing area 81, and sleeved on the partition barrel 21, and is used to carry the laundry in the first washing area 81. Preferably, the laundry can be fixed on the treatment rack body 11; the mounting barrel 18 is rotatably disposed in the second washing area 82, and the mounting barrel 18 and the treatment rack body 11 can be synchronously rotated and fixedly connected together or integrally formed; the second sealing cover 2 is sealed at the barrel mouth of the mounting barrel 18; see Figure 2 A first sealing structure is provided between the second sealing cover 2 and the mounting barrel 18. When the second sealing cover 2 covers the mounting barrel 18, a first seal is formed between the first sealing structure and the mounting barrel 18. The lower surface of the second sealing cover 2 extends toward the direction close to the mounting barrel 18 to form a protrusion 25. The end of the protrusion 25 extends into the mounting barrel 18. A second sealing structure is provided on the side wall of the protrusion 25. When the second sealing cover 2 is covered on the mounting barrel 18, a second seal is formed between the second sealing structure and the mounting barrel 18.

[0057] In this embodiment, two seals are formed between the second sealing cover 2 and the installation barrel 18 to ensure the sealing performance of the partition barrel 21. At the same time, the first sealing structure prevents the water in the first washing area 81 from entering the second washing area 82, and the second sealing structure prevents the water in the partition barrel 21 from entering the first washing area 81, so that the water between the first washing area 81 and the second washing area 82 will not cross-contaminate.

[0058] Further optionally, for details, see Figure 1 、 Figure 2 、 Figure 4 and Figure 7 The first sealing structure includes a first attracting member 3 provided at the edge of the second sealing cover 2 and a second attracting member 7 provided at the mouth of the installation barrel 18. When the second sealing cover 2 covers the installation barrel 18, the first attracting member 3 attracts the second attracting member 7. Optionally, when the material of the first attracting member 3 is iron, the material of the second attracting member 7 is a magnet; when the material of the first attracting member 3 is a magnet, the material of the second attracting member 7 is iron or a magnet with a magnetic property opposite to that of the first attracting member 3. When the second sealing cover 2 is detachably arranged, the material of the first attracting member 3 is preferably iron, and the material of the second attracting member 7 is preferably a magnet, because the second sealing cover 2 can be removed by the user, which may magnetically attract nearby iron products, affecting the experience, and even may magnetically attract dangerous items such as needles and knives. Therefore, making the first attracting member an iron product can avoid attracting the iron products near the placement position of the first attracting member and reduce costs at the same time.

[0059] The second sealing cover 2 and the installation barrel 18 are hermetically sealed by the attraction between the first attracting member 3 and the second attracting member 7. The first attracting member is arranged at the edge of the first sealing cover 1 in a ring shape, or two semi-ring shapes, or multiple arc segments, or multiple blocks. The second attracting member 7 is arranged at the mouth of the installation barrel 18 in a ring shape, or two semi-ring shapes, or multiple arc segments, or multiple blocks. In some embodiments, in order to ensure the tight attraction effect between the first sealing cover 1 and the installation barrel 18, the first attracting member 3 is arranged in a ring shape, so that no matter how the user places the second sealing cover 2 on the mouth of the installation barrel 18, it can be magnetically attracted. At this time, multiple block-shaped second attracting members 7 can be arranged at the mouth of the installation barrel 18. Considering the assembly problem, the complete ring can be cut into two semi-rings for easy assembly. In other embodiments, in order to ensure the tight attraction effect between the first sealing cover 1 and the installation barrel 18, the second attracting member 7 is arranged in a ring shape, so that no matter how the user places the second sealing cover 2 on the mouth of the installation barrel 18, it can be magnetically attracted. At this time, multiple block-shaped first attracting members 3 can be arranged at the edge of the second sealing cover 2, but considering the assembly problem, the complete ring can be cut into two semi-rings for easy assembly. The semi-circular iron ring can be integrally formed by injection molding and arranged on the second sealing cover 2 or at the mouth of the installation barrel 18.

[0060] Further optionally, see Figure 1 , Figure 2 , Figure 4 and Figure 7 , a first mounting groove 23 is provided on the lower surface of the edge of the second sealing cover 2, and the first attracting member 3 is disposed in the first mounting groove 23. A second mounting groove 821 corresponding to the first attracting member 3 is provided at the mouth of the mounting barrel 18, and the second attracting member 7 is disposed in the second mounting groove 821. The first mounting groove 23 matches the length of the first attracting member 3, and the second mounting groove 821 matches the second attracting member 7. For example, as Figure 1 shown, when the first attracting member is annular, the first mounting groove 23 is an annular groove, and when the second attracting member 7 is block-shaped, as Figure 1 is provided with four magnet blocks, which are evenly distributed on the top of the partition barrel 21 respectively, and the second mounting groove is a groove matching the size of the block-shaped second attracting member 7.

[0061] Further optionally, see Figure Figure 4 , the first sealing structure further includes a first sealing ring 5. The first sealing ring 5 includes a concave cavity, an upper wall surface and a lower wall surface forming the concave cavity. A limiting groove 231 is opened on the lower end surface of the first mounting groove 23, and a convex rib matching the limiting groove 231 is formed on the lower wall surface, and the convex rib protrudes into the concave cavity; the first sealing ring 5 is disposed at the opening of the first mounting groove 23, the upper wall surface extends into the first mounting groove 23 from the opening of the first mounting groove 23, the lower wall surface covers the lower end surface of the first mounting groove 23, the first attracting member 3 is limited between the first mounting groove 23 and the concave cavity, and the convex rib is limited in the limiting groove 231, so as to fix the first sealing ring 5. At the same time, the first sealing ring 5 plays a role in further sealing the second washing area 82, preventing the water in the first washing area 81 from flowing into the second washing area 82, resulting in cross-contamination of clothes; at the same time, the first sealing ring 5 can also play a certain buffering role during the process of closing the second sealing cover 2, improving the user experience. In addition, when the material of the first attracting member 3 is a magnet, the setting of the first sealing ring 5 can also prevent external water from entering the first mounting groove 23, causing the magnet to rust and reducing the service life of the magnet. Further optionally, a second mounting groove corresponding to the first attracting member 3 is provided at the mouth of the mounting barrel 18, and the second attracting member 7 is disposed in the second mounting groove 821.

[0062] Further optionally, see Figure 1 and Figure 2, a retaining rib 83 is provided on the end face of the barrel opening of the installation barrel 18, and the second attracting member 7 is located on the side of the retaining rib 83 close to the barrel opening of the installation barrel 18; when the second sealing cover 2 covers the installation barrel 18, the second sealing cover 2 is limited within the area surrounded by the retaining rib 83, and the first sealing ring 5 is in interference fit with the retaining rib 83. The setting of the first retaining rib 83 not only further improves the sealing performance through interference fit with the second sealing cover 2, but also can prevent the water on the end face of the barrel opening of the installation barrel 18 from entering the interior of the second washing area 82.

[0063] Further optionally, see Figure 2 , Figure 4 , the second sealing structure is the second sealing ring 4 provided on the side wall of the convex portion 25. When the second sealing cover 2 seals the installation barrel 18, the second sealing ring 4 is in interference fit with the inner wall of the installation barrel 18. The second sealing ring 4 is installed on the side wall of the convex portion 25 of the second sealing cover 2, and the interference fit between the second sealing cover 2 and the inner wall of the installation barrel 18 plays a further sealing role, that is, provides a relatively closed space for the second washing area 82, and can prevent the washing water flow from splashing (flowing into) the first washing area 81 during the washing process of the clothes in the second washing area, causing cross-contamination.

[0064] Further optionally, see Figure 1 , in some embodiments, the first sealing cover 1 is in a plate shape, as Figure 1 and Figure 2 shown, and is provided at the barrel opening of the outer barrel 20 in an openable and closable manner to cover the first washing area 81 and the second washing area 82; when the first sealing cover 1 covers the first washing area 81 and the second washing area 82, and the second sealing cover 2 covers the partition barrel 21, the second sealing cover 2 is located below the first sealing cover 1, and a third sealing ring is further provided at the edge of the first sealing cover 1. When the first sealing cover 1 covers the first washing area 81 and the second washing area 82, the third sealing ring seals with the outer barrel 20.

[0065] In other embodiments, the first sealing cover 1 is in a ring shape and is provided at the barrel opening of the outer barrel 20 in an openable and closable manner to cover the first washing area 81; when the first sealing cover 1 covers the first washing area 81 and the second sealing cover 2 covers the partition barrel 21, the second sealing cover 2 is located within the ring of the first sealing cover 1. A third sealing ring is provided on the outer ring of the first sealing cover 1, and a fourth sealing ring is provided on the inner ring of the first sealing cover 1. When the first sealing cover 1 covers the first washing area 81, the third sealing ring and the fourth sealing ring respectively seal with the outer ring wall and the inner ring wall of the first washing area.

[0066] This embodiment also proposes a washing machine, which includes the above-mentioned sealing cover.

[0067] Further optionally, see Figure 8, in the washing machine of this embodiment, an air inlet 201 and an outer tub air outlet 2022 are provided on the side wall of the outer tub 20. A first drying path for the drying hot air to flow through the first washing area 81 is formed between the air inlet 201 and the outer tub air outlet 2022 of the outer tub 20; a separator tub air outlet 2031 is provided at the bottom of the separator tub 21, and a second drying path for the drying hot air to flow through the second washing area 82 is formed between the air inlet 201 and the separator tub air outlet 2031;

[0068] The first drying path and the second drying path can be controlled to simultaneously perform drying treatment on the first washing area 81 and the second washing area 82.

[0069] A drying air duct is provided on the outer tub 20, including an air inlet 201 provided on the side wall of the outer tub 20, a first air outlet 2021 provided at the bottom of the first washing area, and a separator tub air outlet 2031 provided at the bottom of the second washing area. The drying hot air enters the first washing area and the second washing area from the air inlet 201 and can flow out through the first air outlet 2021 and the separator tub air outlet 2031 respectively. Preferably, the air inlet 201 is provided at the top of the side wall of the outer tub 20 to realize upper air inlet and bottom air outlet, extend the flow path of the drying hot air, and improve the drying effect. The first sealing cover 1 can seal the outer tub 20 so that the drying hot air can only flow inside the outer tub 20. The second air permeable holes 26 provided on the second sealing cover 2 can also allow the hot air to enter and exit the second washing area 82 to maintain the pressure balance inside the second washing area 82.

[0070] A separator tub 21 is provided inside the outer tub 20. For details, see Figure 9 , the separator tub 21 is connected to the bottom wall of the outer tub 20. The annular space between the separator tub 21 and the outer tub 20 forms the first washing area, and the second washing area is formed inside the separator tub 21. The separator tub 21 separates the first washing area and the second washing area into two independent washing areas to avoid cross-contamination of washing water. However, the drying hot air enters the first washing area from the air inlet 201 and can flow over the separator tub 21 into the second washing area, achieving the effect of drying two washing areas with one set of drying system. Independent inlet and drainage channels are respectively provided inside and outside the separator tub 21, so that the two washing areas can be washed independently to avoid cross-contamination caused by the interconnection of washing water. For example, the first washing area can be used for washing ordinary clothes, such as coats, shirts, etc., and the second washing area can be used for washing close-fitting clothes, such as underwear, bras, etc. The first washing area and the second washing area are independent of each other and can wash different clothes simultaneously.
