Description

Technical Field

[0001] This utility model relates to a washing tub that can be patted and washed, belonging to the field of pulsator washing machines. Background Technology

[0002] A top-loading washing machine is a common washing tool. The inner drum of a traditional single-drum top-loading washing machine has a smooth, rounded inner wall made of plastic or stainless steel. Its washing mechanism mainly relies on the rotation of the pulsator to drive the water flow to impact the clothes to achieve cleaning.

[0003] However, traditional top-loading washing machines cannot provide sufficient frictional resistance on their smooth inner walls during the washing process, causing clothes to slip excessively. The clothes lack effective mechanical action against the inner drum wall, and the ability to remove stubborn stains by simply relying on the impact of water flow is limited, resulting in low washing efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a washing machine tub with a detachable washing module.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A washable tub includes a tub body and an impeller located at the bottom of the tub body. An internal brush is provided inside the tub. As the impeller rotates, the laundry comes into contact with and rubs against the internal brush to achieve washing. The internal brush is a silicone rubber elastic sheet. The plane of the silicone rubber elastic sheet intersects with the rotation direction of the impeller, forming a barrier. The elastic deformation of the silicone rubber elastic sheet tends to be consistent with the rotation direction of the impeller. The thickness of the silicone rubber elastic sheet along the elastic deformation direction is greater than or equal to 1 mm and less than or equal to 10 mm. As the impeller rotates, the laundry compresses the silicone rubber elastic sheet, causing it to deform. The deformed silicone rubber elastic sheet generates a rebound force that pats the laundry.

[0006] The beneficial effects of using this utility model are as follows: Firstly, the inner brush of this invention is made of silicone rubber elastic sheet, and the plane of the silicone rubber elastic sheet intersects with the rotation direction of the impeller to form a barrier. Therefore, when washing clothes, the laundry rotates inside the tub and is squeezed against the silicone rubber elastic sheet, causing the sheet to deform. The silicone rubber elastic sheet has a certain rebound force upon rebound, thus patting the clothes and producing a patting effect. This process repeats, similar to simulating the patting action of a person hand-washing clothes. This patting method can gradually remove stubborn stains. Combined with the impact of water flow on the laundry, it can improve the washing effect, significantly enhancing the removal of stubborn stains such as oil and sweat.

[0007] Secondly, due to the inherent damping effect of the silicone rubber surface, it can provide a certain amount of friction when in contact with the laundry, allowing for brushing. Thus, the silicone rubber elastic sheet combines the frictional brushing similar to a traditional brush with the patting function that traditional brushes lack, further enhancing the washing effect.

[0008] Preferably, the protrusion height of the silicone rubber elastic sheet is greater than or equal to 5 mm.

[0009] Preferably, the inner brush includes a wall brush on the inner side wall of the barrel; and / or a bottom brush on the bottom of the barrel; and / or, the impeller is provided with a central rod, and the inner brush is a central rod provided on the central rod.

[0010] Preferably, when the inner brush of the bucket is a bottom brush, the bottom brush includes a first bottom brush disposed on the surface of the impeller and / or a second bottom brush disposed on the bottom wall of the bucket.

[0011] Preferably, the surface of the silicone rubber elastic sheet is provided with a plurality of friction protrusions for increasing friction; and / or, the silicone rubber elastic sheet is provided with bristles.

[0012] Preferably, when the surface of the silicone rubber spring has friction protrusions, the height of the friction protrusions is 0.5 to 10 mm, and the spacing between them is 0.5 to 10 mm.

[0013] Preferably, the brush inside the bucket is detachably connected to the bucket body or the impeller.

[0014] Preferably, the inner side wall of the barrel is provided with a first mounting groove, and the wall brush is detachably installed in the mounting groove; and / or, the surface of the impeller is provided with a second mounting groove, and the first bottom brush is detachably installed in the second mounting groove; and / or, the bottom wall of the barrel is provided with a third mounting groove, and the second bottom brush is detachably installed in the third mounting groove.

[0015] Preferably, the first, second, or third mounting slot is a dovetail slot, the connector is provided with a dovetail-shaped locking head that mates with the dovetail slot, the connector is also provided with a T-shaped plug at the other end of the dovetail-shaped locking head, and the first, second, or third mounting slot is provided with an embedding groove that mates with the T-shaped plug.

[0016] Preferably, the inner brush includes an elastic sheet body and a connector, the elastic sheet body is mounted on the connector, and the connector is installed in the first mounting groove, the second mounting groove, or the third mounting groove.

[0017] Preferably, the center rod of the impeller is fitted with a silicone rubber sleeve, and the center rod and the silicone rubber sleeve are integrally formed.

[0018] Preferably, the center rod of the impeller is fitted with a silicone rubber sleeve, and the center rod is provided with a fourth mounting groove, through which the silicone rubber sleeve is installed on the center rod.

[0027] like Figures 1-2 As shown, this embodiment includes a tub body 1 and a pulsator 2 located at the bottom of the tub body 1. An internal brush 3 is provided inside the tub body 1. The laundry is washed by contacting and rubbing against the internal brush 3 under the rotation of the pulsator 2. The internal brush 3 is a silicone rubber elastic sheet. The plane of the silicone rubber elastic sheet intersects with the rotation direction of the pulsator 2, forming a barrier. The elastic deformation of the silicone rubber elastic sheet tends to be consistent with the rotation direction of the pulsator 2. The thickness of the silicone rubber elastic sheet along the elastic deformation direction is preferably greater than or equal to 1 mm and less than or equal to 10 mm. The protrusion height of the silicone rubber elastic sheet is greater than or equal to 5 mm. After the laundry rotates with the pulsator 2, it squeezes the silicone rubber elastic sheet to cause deformation. After deformation, the silicone rubber elastic sheet generates a rebound force to beat the laundry.

[0028] With this design, firstly, the inner brush 3 in this embodiment is a silicone rubber elastic sheet. When washing clothes, the laundry rotates inside the tub and is squeezed against the silicone rubber elastic sheet, causing the sheet to deform. When the sheet rebounds, it pats the clothes. This repeated patting improves the washing effect and significantly enhances the removal of stubborn stains such as oil and sweat. Secondly, the silicone rubber material itself has a certain damping, which can provide a certain friction when in contact with the laundry, further improving the washing effect.

[0029] It should be noted that in this embodiment, the thickness of the silicone rubber elastic sheet along the elastic deformation direction is selected to be greater than or equal to 1 mm and less than or equal to 10 mm. If the thickness is less than 1 mm, the elasticity of the silicone rubber elastic sheet may be too small, resulting in failure to rebound or a small slapping force when rebounding, leading to poor washing effect. If the thickness is greater than 10 mm, it may be difficult to deform, or the slapping force when rebounding may be too large, damaging the laundry.

[0030] Regarding the protrusion height of silicone rubber elastic sheets, the protrusion height referred to in this article is the effective deformation height of the elastic silicone rubber sheet, that is, the distance between the outermost and innermost free ends of the elastic silicone rubber sheet. If this protrusion height is too small, it will weaken the deformation ability of the silicone rubber elastic sheet and reduce the washing effect.

[0031] In this embodiment, it is preferable to provide an inner brush 3 on both the inner wall of the tub body 1 and the bottom of the washing tub. This arrangement allows the laundry to be rubbed and patted from multiple directions, further improving the washing effect. Of course, in other embodiments, the inner brush 3 may be provided only on one or two of the inner wall of the tub body 1, the bottom of the tub body 1, and the central rod 5. Such implementation methods all fall within the protection scope of this utility model.

[0032] It should be noted that, regarding the placement of the inner brush 3 on the inner wall of the barrel 1, since the barrel 1 used in this embodiment is square, in order to maintain the aesthetics of the internal structure of the product, this embodiment preferably places the inner brush 3 at two adjacent opposite corners of the barrel 1 and the middle of the other inner wall. In other embodiments, the inner brush 3 can also be placed at the four inner corners or the middle of the four inner walls. If the inner wall is circular, the inner brush 3 can also be evenly distributed. The number of inner brushes 3 is preferably 2 to 8. If there are fewer than 2, the friction provided by the inner brush 3 may be insufficient, and the expected cleaning efficiency may not be achieved. If there are more than 8, the friction may be too great, affecting the cleaning efficiency. All of the above embodiments fall within the protection scope of this utility model.

[0033] For the inner brush 3 at the bottom of the washing tub, in this embodiment, a first bottom brush is preferably provided on the surface of the impeller 2. The first bottom brush rotates with the impeller 2. In other embodiments, a second bottom brush is also provided on the bottom wall of the tub body 1. The second bottom brush is fixed on the bottom wall of the tub body 1. The bottom brush can pat and wash the laundry from below, improving the washing effect.

[0034] Please refer to the specific structure of the silicone rubber elastic sheet. Figure 3 As shown in the figure, the surface of the silicone rubber elastic sheet is provided with a plurality of friction protrusions 321 for increasing friction. The friction protrusions 321 rub against the washing material to further improve washing efficiency and cleaning effect.

[0035] It should be noted that, in order to further improve the scrubbing ability of the silicone rubber elastic sheet, bristles can also be provided on the silicone rubber elastic sheet. Bristles and friction protrusions can coexist, or only one of them can be selected.

[0036] The height of the friction protrusions 321 is preferably 0.5 to 10 mm. If the protrusion height is less than 0.5 mm, it cannot provide sufficient friction, which may result in an unsatisfactory cleaning effect. If the protrusion height is greater than 10 mm, it may result in a large friction, which may affect the cleaning efficiency. Similarly, the spacing is preferably 0.5 to 10 mm. If the spacing is less than 0.5 mm, the friction protrusions 321 are too densely arranged, which may result in a large friction, which may affect the cleaning efficiency. If the spacing is greater than 10 mm, the friction protrusions 321 are too sparsely arranged, which cannot provide sufficient friction, which may result in an unsatisfactory cleaning effect.

[0037] The inner brush 3 is detachably connected to the barrel body 1 or the impeller 2. The inner wall of the barrel body 1 is provided with a first mounting groove 4, and the wall brush is detachably installed in the mounting groove. The surface of the impeller 2 is provided with a second mounting groove, and the first bottom brush is detachably installed in the second mounting groove. In other embodiments, the bottom wall of the barrel body 1 is also provided with a third mounting groove, and the second bottom brush is detachably installed in the third mounting groove. This arrangement facilitates user disassembly and assembly, allowing users to easily clean the inner wall of the barrel body 1 and the inner brush 3, preventing the accumulation of bacteria or the generation of odors over long-term use, and improving hygiene.

[0038] See Figure 3 The inner brush 3 includes an elastic sheet body 32 and a connector 31. The elastic sheet body 32 is mounted on the connector 31, which is installed in the first mounting groove 4, the second mounting groove, or the third mounting groove. Using the connector 31 to install the elastic sheet body 32 improves installation stability and connection strength, making it less likely for the elastic sheet body 32 to detach during washing. It should be noted that the connector 31 improves connection strength and facilitates the installation of the silicone rubber elastic sheet. The silicone rubber elastic sheet itself is relatively soft, resulting in poor stability after installation, and its surface has damping properties. Directly inserting the elastic sheet body 32 presents significant resistance and is inconvenient. The connector 31, designed as a plastic or metal part, offers better strength and a smoother surface, facilitating installation. It should be noted that in other embodiments, the connector can be an integral part of the elastic sheet body.

[0039] Figures 2-3The figure shows the specific structure of the first mounting slot 4. The first mounting slot 4 is a dovetail slot 41. The connector 31 is provided with a dovetail-shaped locking head 311 that cooperates with the dovetail slot 41. The connector 31 is also provided with a T-shaped plug 312 at the other end of the dovetail-shaped locking head 311. The first mounting slot 4 is provided with an embedding groove 42 that cooperates with the T-shaped plug 312. When the user installs the brush 3 in the mounting bucket, he inserts the T-shaped plug 312 into the T-shaped groove and then slides it to the position of the dovetail slot 41 to lock it. Disassembly is done by reversing the operation.

[0040] This embodiment uses the dovetail groove 41 and T-shaped groove structure to form a double locking mechanism, which greatly improves the stability of the inner brush 3 during installation and reduces the probability of the inner brush 3 falling off during washing. At the same time, this structure is easy for users to disassemble, making it convenient for users to replace or clean the inner brush 3.

[0041] See Figure 4 The impeller 2 is also detachably provided with a central rod 5, and a silicone rubber sleeve 51 is provided on the central rod 5. The silicone rubber sleeve 51 is preferably made of silicone rubber. The rod brush 52 is preferably an integral structure with the silicone rubber sleeve 51. In other embodiments, a fourth mounting groove may be provided on the central rod. The specific structure of the fourth mounting groove may be the same as the structure of the first mounting groove. The silicone rubber sleeve is installed on the central rod through the fourth mounting groove.

[0042] It should be noted that, in order to reduce the number of parts and facilitate the installation of the rod brush 52, the rod brush 52 and the silicone rubber sleeve 51 are integrated into one structure. In other embodiments, the rod brush can also adopt the above-mentioned detachable inner brush structure, and such implementation also falls within the protection scope of this utility model.

[0043] The material of the elastic sheet body 32 is preferably silicone rubber with a Shore A hardness of 30 to 70. If the hardness is less than 30, the silicone rubber may be too soft and the rebound force may be small, which may not achieve a good washing effect. If the hardness is greater than 70, the silicone rubber may be too hard and difficult to deform, which may also damage the clothing fibers.

[0044] The plane of the silicone rubber elastic sheet is perpendicular to the rotation direction of the impeller 2. This arrangement maximizes the contact area between the laundry and the silicone rubber elastic sheet as the laundry rotates within the tub 1, resulting in maximum compression of the elastic sheet and greater tumbling and washing effect on the laundry, thus improving the washing performance. Of course, in other embodiments, the silicone rubber elastic sheet and the impeller rotation direction can be at other angles, such as 80 degrees, 100 degrees, etc.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
