Description

Technical Field

[0001] This invention relates to the field of clothing processing technology, specifically providing a washing device. Background Technology

[0002] Foam plays a crucial role in the washing process. It helps detergent disperse better in clothes and water, enhances the absorption, encapsulation, and isolation of stains, thereby improving washing results. Traditional pulsator washing machines cannot produce enough foam when the amount of detergent added is small, limiting their washing efficiency. On the other hand, when too much detergent is added, although more foam is produced, detergent residue can remain on clothes after washing, affecting wearing comfort and health.

[0003] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem that existing washing equipment cannot generate enough foam when the amount of detergent added is small.

[0005] The present invention provides a washing device, which includes a washing tub, a pulsator, a drive motor, a first friction element and a second friction element. The pulsator is installed in the washing tub, and the drive motor can drive the pulsator to rotate. The first friction element is disposed on the pulsator, and the second friction element is disposed on the washing tub. When the pulsator rotates, the first friction element and the second friction element can rub against each other to generate bubbles.

[0006] In the preferred embodiment of the above-mentioned washing equipment, the second friction member includes a support part and a friction part, a cavity is provided between the support part and the friction part, the outer surface of the friction part communicates with the cavity, the support part is fixed to the bottom of the washing tub, and the friction part abuts against the first friction member.

[0007] In the preferred embodiment of the above-mentioned washing equipment, the first friction element includes a fixed base and bristles, the bristles are disposed on the fixed base, the fixed base is fixedly installed on the impeller, and the bristles abut against the friction element.

[0008] In the preferred embodiment of the above-mentioned washing equipment, the friction part is provided with a plurality of through holes, and the outer surface of the friction part is connected to the cavity through the through holes.

[0009] In the preferred embodiment of the above-mentioned washing equipment, the impeller has a fixing hole corresponding to the brush bristles, and the brush bristles pass through the fixing hole and abut against the friction part.

[0010] In the preferred embodiment of the above-mentioned washing equipment, a plurality of first friction elements are provided, and the plurality of first friction elements are arranged at intervals along the circumference of the impeller.

[0011] In the preferred embodiment of the above washing equipment, a positioning post is provided on the side of the fixed base, and the impeller is provided with a positioning hole corresponding to the positioning post, and the positioning post is inserted into the positioning hole.

[0012] In the preferred embodiment of the above-mentioned washing equipment, both the support portion and the friction portion are annular.

[0013] In the preferred embodiment of the above-mentioned washing equipment, the impeller is provided with a plurality of lifting ribs at intervals, and the lifting ribs are provided with mesh holes.

[0014] In the preferred technical solution of the above-mentioned washing equipment, the washing equipment is a washing machine or a washer-dryer combo.

[0015] Those skilled in the art will understand that the technical solution of the present invention provides a washing device, which includes a washing tub, a pulsator, a drive motor, a first friction element, and a second friction element. The pulsator is installed in the washing tub, and the drive motor drives the pulsator to rotate. The first friction element is disposed on the pulsator, and the second friction element is disposed on the washing tub. When the pulsator rotates, the first and second friction elements can rub against each other to generate bubbles. By adopting the above technical solution, the present invention can solve the problem that existing washing devices cannot generate sufficient foam when the amount of detergent added is small. Specifically, when the pulsator rotates under the drive motor, the first and second friction elements continuously contact and rub against each other. This friction not only promotes the mixing of air and water in the washing water, but also generates tiny eddies due to friction, further accelerating the generation and refinement of bubbles. Even when the amount of detergent added is small, the bubbles generated by physical friction can effectively increase the amount of foam in the washing water, thereby improving washing efficiency and enhancing the cleaning ability of clothes.

[0016] Furthermore, the second friction member of the present invention includes a support portion and a friction portion, with a cavity provided between the support portion and the friction portion. The outer surface of the friction portion communicates with the cavity. The support portion is fixed to the bottom of the washing tub, and the friction portion abuts against the first friction member. By communicating the outer surface of the friction portion with the cavity, washing water can more easily enter and remain on the friction surface during the friction process, thereby increasing the mixing opportunity of air and water and improving the efficiency of bubble generation. As a result, even with a small amount of detergent added, sufficient foam can be formed in the washing water. This foam can more effectively penetrate into the clothing fibers to remove stains and odors, thereby improving the washing effect.

[0017] Furthermore, the first friction element of the present invention includes a fixed base and bristles. The bristles are disposed on the fixed base, which is fixedly mounted on the impeller, and the bristles abut against the friction part. The bristles allow the first friction element to contact the friction part more closely, thereby generating a stronger frictional effect when the impeller rotates. This strong frictional effect not only further promotes the mixing of air and water but also accelerates the generation and refinement of bubbles. Due to the close contact and strong friction between the bristles and the friction part, the bubbles in the washing water become smaller and more evenly distributed, thereby further improving washing efficiency.

[0018] Furthermore, the friction part has multiple through holes, and its outer surface is connected to the cavity through these holes. This design allows washing water to freely permeate from the outer surface into the cavity through the through holes, forming eddies and bubbles within the cavity. Simultaneously, the bubbles within the cavity can also escape to the outer surface through the through holes, further mixing with the washing water to create more foam.

[0019] Furthermore, the impeller has fixing holes corresponding to the brush bristles, through which the bristles pass and abut against the friction part. This structural design ensures that the bristles can pass through and be fixed accurately on the impeller, allowing them to maintain a stable posture and position as the impeller rotates. During the rotation of the impeller, the bristles continuously generate friction with the friction part. This continuous friction not only helps to enhance the washing effect but also promotes the generation and refinement of bubbles.

[0020] Furthermore, multiple first friction elements are provided, which are spaced apart along the circumference of the impeller. This structure ensures that during the rotation of the impeller, the bristles of each second friction element continuously rub against the friction part. This continuous friction helps to further promote the generation and refinement of bubbles, thereby quickly breaking down stains and odors on clothes and improving washing efficiency.

[0021] Furthermore, both the support and friction parts are annular. This structural design ensures maximum contact area with the bristles, allowing the bristles to be evenly distributed across the entire circumference of the friction part during the rotation of the impeller, thus achieving a comprehensive washing effect.

[0022] Furthermore, the impeller is equipped with multiple lifting ribs at intervals, each with a mesh opening. These ribs allow for a stronger interaction with the water flow and clothing, generating more powerful water currents. This power not only helps to thoroughly disperse and suspend the clothing in the water, but each lifting rib also has a number of mesh openings that allow water and detergent to pass through, creating richer water flow and foam around the ribs. This allows the wash water to penetrate deeper into the clothing fibers, removing stains and odors. Attached Figure Description

[0034] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. For example, although the following embodiments are described in conjunction with a washing machine, the washing apparatus provided by the present invention is equally applicable to other products that need to solve the problem of insufficient foam generation.

[0035] It should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly, for example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] Based on the background art, existing washing equipment fails to generate sufficient foam when the detergent dosage is low. This invention provides a washing device designed to effectively solve the problem of insufficient foam generation when the detergent dosage is low by promoting air-water mixing in the washing water through friction during the rotation of the impeller, thereby generating more bubbles.

[0037] First refer to Figure 1 and Figure 2 ,in, Figure 1 This is a schematic diagram of the washing device of the present invention; Figure 2 This is an exploded view of the washing device of the present invention.

[0038] like Figure 1 and Figure 2 As shown, the present invention provides a washing device, which includes a washing tub 1, a pulsator 2, a drive motor (not shown in the figure), a first friction element 3, and a second friction element 4. The pulsator 2 is installed in the washing tub 1, and the drive motor can drive the pulsator 2 to rotate. The first friction element 3 is disposed on the pulsator 2, and the second friction element 4 is disposed on the washing tub 1. When the pulsator 2 rotates, the first friction element 3 and the second friction element 4 can rub against each other to generate bubbles.

[0039] The washing tub 1, as the main container of the washing equipment, holds the clothes to be washed and the washing water. The impeller 2, installed inside the washing tub 1, rotates using a drive motor to tumble and scrub the clothes, achieving a cleaning effect. The drive motor is the power source for the impeller's rotation; it transmits power to the impeller 2 through a transmission mechanism (such as belts or gears), enabling the impeller 2 to rotate at a predetermined speed and direction. When the impeller 2 rotates under the drive motor, the first friction element 3 and the second friction element 4 continuously contact and generate friction. This friction not only promotes the mixing of air and water in the washing water but also, due to the tiny eddies generated by the friction, further accelerates the formation and refinement of bubbles. Therefore, even with a small amount of detergent, sufficient foam can be generated through physical friction, ensuring that clothes are thoroughly and deeply cleaned. Furthermore, it reduces reliance on detergent, helping to lower washing costs and reduce environmental pollution from chemical detergents, providing users with a more convenient and economical washing experience. Furthermore, in this invention, the rotational speed of the impeller 2 can be adjusted by regulating the power of the drive motor. Thus, regardless of whether the clothes are lightly or heavily soiled, this invention can optimize the effect of friction foaming by adjusting the washing program and the rotational speed of the impeller 2, thereby meeting different washing needs.

[0040] Preferably, such as Figure 5As shown, the second friction member 4 includes a support part 41 and a friction part 42. A cavity is provided between the support part 41 and the friction part 42. The outer surface of the friction part 42 communicates with the cavity. The support part 41 is fixed to the bottom of the washing tub 1, and the friction part 42 abuts against the second friction member 4.

[0041] The support part 41 serves as the foundation of the entire second friction element 4, ensuring its secure fixation to the bottom of the washing tub 1 and preventing damage from vibrations and impacts generated during the rotation of the impeller 2. The friction part 42 is the portion that directly contacts and generates friction with the first friction element 3. A cavity is positioned between the support part 41 and the friction part 42, acting as an "incubator" for bubble generation. When the friction part 42 rubs against the first friction element 3 and undergoes relative movement, air or water within the cavity can be effectively compressed and released through the outer surface of the friction part 42, forming bubbles. This ensures that the bubbles can smoothly escape from the cavity and disperse into the washing water. The outer surface of the friction part 42 is connected to the cavity; this design allows washing water to more easily enter and remain on the friction surface during friction, increasing the mixing opportunity between air and water, promoting bubble generation, and enabling a more even distribution of bubbles within the washing tub 1, further improving the washing effect. Therefore, through the above scheme, the bubble generation efficiency is greatly improved, resulting in sufficient foam formation in the washing water even with a small amount of detergent added. These foams can penetrate clothing fibers more effectively, removing stains and odors, thus improving washing results. Furthermore, they reduce reliance on detergent, meaning lower washing costs and less chemical contamination. Also, since bubble formation relies primarily on physical friction rather than chemical reactions, energy consumption is reduced. Moreover, due to the cavity design, some vibrations and noise generated by friction can be absorbed and buffered by the air or water within the cavity, thereby reducing noise levels during the washing process and improving the user experience.

[0042] Preferably, such as Figure 1 and Figure 4 As shown, the first friction element 3 includes a fixed base 31 and bristles 32. The bristles 32 are disposed on the fixed base 31, and the fixed base 31 is fixedly installed on the impeller 2. The bristles 32 abut against the friction part 42.

[0043] The fixing seat 31, serving as a support structure for the bristles 32, is securely mounted on the impeller 2. This ensures that the bristles 32 do not loosen or fall off when the impeller 2 rotates, maintaining a stable position and posture, thus forming effective frictional contact with the friction part 42 of the second friction member 4. The bristles 32 are the part of the first friction member 3 that directly contacts and generates friction with the friction part 42 of the second friction member 4. In this invention, the bristles 32 are made of soft and elastic materials, such as nylon or polyester fibers, to ensure sufficient frictional force is generated during the friction process without damaging the washing tub 1 or clothing. The design of the bristles 32 allows the first friction member 3 to contact the friction part 42 of the second friction member 4 more closely, resulting in stronger friction when the impeller 2 rotates. This strong friction not only promotes the mixing of air and water but also accelerates the generation and refinement of bubbles. In addition, due to the close contact and strong friction between the bristles 32 and the friction part 42, the bubbles in the washing water are smaller and more evenly distributed. These tiny bubbles can penetrate into the clothing fibers more effectively to remove stains and odors, thereby improving washing efficiency.

[0044] Preferably, such as Figure 5 As shown, the friction part 42 has multiple through holes 421, and the outer surface of the friction part 42 is connected to the cavity through the through holes 421.

[0045] The through-hole 421 extends through the entire thickness of the friction part 42, thus directly connecting the outer surface with the internal cavity. This allows for stronger water flow disturbance and vortex effect when the impeller 2 rotates and the friction part 42 contacts the bristles 32. This enables the washing water to freely penetrate from the outer surface into the cavity through the through-hole 421, forming vortices and bubbles within the cavity. Simultaneously, the bubbles within the cavity can also escape to the outer surface through the through-hole 421, further mixing with the washing water to form a large number of microbubbles. These bubbles can more effectively penetrate into the clothing fibers during the washing process, improving the washing effect and effectively removing stains and odors, allowing users to wash clothes faster and cleaner.

[0046] Preferably, such as Figure 3 As shown, the impeller 2 has a fixing hole 21 corresponding to the bristles 32, and the bristles 32 pass through the fixing hole 21 and abut against the friction part 42.

[0047] In this invention, the impeller 2 has fixing holes 21 corresponding to the bristles 32. The shape, size, and position of these holes match the bristles 32, ensuring that the bristles 32 can pass through and be fixed accurately on the impeller 2. This allows the bristles 32 to maintain a stable posture and position when the impeller 2 rotates, preventing them from falling off or shifting due to vibration or impact. After passing through the fixing holes 21, the ends of the bristles 32 abut tightly against the friction part 42 in the second friction member 4. During the rotation of the impeller 2, the bristles 32 continuously rub against the friction part 42. This continuous friction not only enhances the washing effect but also promotes the generation and refinement of bubbles. Bubbles play a crucial role in the washing process; they can more comprehensively cover the surface of clothing and penetrate deep into the fibers, effectively removing stains and odors, thus improving washing efficiency and quality.

[0048] Preferably, such as Figure 1 and Figure 2 As shown, multiple first friction elements 3 are provided, and the multiple first friction elements 3 are arranged at intervals along the circumference of the impeller 2.

[0049] Multiple first friction elements 3 are spaced apart circumferentially along the impeller 2, ensuring that the friction between the first friction elements 3 and the second friction elements 4 is evenly distributed throughout the washing process, making the friction more uniform and comprehensive. This uniformity helps improve the consistency of the washing effect and reduce washing dead spots. Specifically, during the rotation of the impeller 2, the bristles 32 of each first friction element 3 continuously rub against the friction part 42. This continuous friction helps promote the generation and refinement of bubbles, which helps to quickly break down stains and odors on clothes and improve washing efficiency. Although multiple first friction elements 3 are added, the contact points between the first friction elements 3 and the second friction elements 4 also increase accordingly during the rotation of the impeller 2, thereby enhancing the overall friction effect and bubble generation capacity, further enhancing washing efficiency and washing effect. Therefore, it can actually reduce energy consumption during the washing process, because less washing time and less detergent means lower energy consumption.

[0050] Preferably, such as Figure 1 and Figure 4 As shown, a positioning post 311 is provided on the side of the fixed base 31, and the impeller 2 has a positioning hole 22 corresponding to the positioning post 311. The positioning post 311 is inserted into the positioning hole 22.

[0051] The insertion connection between the positioning pin 311 and the positioning hole 22 effectively prevents the fixing seat 31 from loosening or falling off during the rotation of the impeller 2. During installation, the positioning pin 311 on the fixing seat 31 is aligned with the positioning hole 22 on the impeller 2 and gently inserted, improving the reliability and durability of the connection. This stable connection ensures that the first friction element 3 can work continuously and stably. Furthermore, it allows the fixing seat 31 to be precisely installed in the designated position on the impeller 2. This high-precision installation helps optimize the contact effect between the bristles 32 and the friction part 42, thereby improving washing performance. When it is necessary to replace or repair the first friction element 3, the fixing seat 31 can be easily removed from the impeller 2 by simply pulling out the positioning pin 311. This convenient disassembly method simplifies the maintenance process and reduces maintenance costs.

[0052] Furthermore, the impeller 2 in this invention has a first threaded hole, and the mounting base 31 has a second threaded hole corresponding to the first threaded hole. The bolt can pass through both the first and second threaded holes in one operation. Using a bolt as a connector, by passing it through the first and second threaded holes and tightening it, makes the connection between the impeller 2 and the mounting base 31 more stable and reliable. During the washing process, even under significant impact and vibration, the bolt can maintain its connection without loosening, ensuring the normal operation of the washing equipment.

[0053] Preferably, such as Figure 5 As shown, both the support part 41 and the friction part 42 are annular.

[0054] As a key component for fixing and supporting the friction part 42, the annular design of the support part 41 provides more uniform support force. The annular structure allows the support part 41 to maintain a stable posture when the impeller 2 rotates, reducing noise and wear caused by vibration or imbalance. Simultaneously, the annular support part 41 effectively disperses the force from the rotation of the impeller 2, protecting the friction part 42 from excessive impact and stress concentration, thereby extending its service life. The friction part 42, as the part that directly contacts and generates friction with the bristles 32, has an annular design that maximizes the contact area with the bristles 32. This design allows the bristles 32 to be evenly distributed across the entire circumference of the friction part 42 during the rotation of the impeller 2, achieving a comprehensive washing effect. The annular friction part 42 also promotes the flow of washing water and the generation of bubbles. When washing water permeates into the cavity through the through-hole 421, the annular friction part 42 guides the water flow to form eddies and bubbles, which can penetrate deeper into the clothing fibers, improving the washing effect.

[0055] Preferably, such as Figure 3 As shown, the impeller 2 is provided with multiple lifting ribs 23 at intervals, and the lifting ribs 23 are provided with mesh holes 231.

[0056] The lifting ribs 23 are raised sections on the impeller 2, spaced apart circumferentially. Their main function is to lift and rub the clothes as the impeller 2 rotates. By spaced out multiple lifting ribs 23, the clothes are ensured to be thoroughly tumbled and rubbed during washing, thus improving the washing effect. Furthermore, as the impeller 2 rotates, the lifting ribs 23 interact more strongly with the water flow and the clothes, generating stronger water current dynamics. These dynamics not only help to thoroughly disperse and suspend the clothes in the water but also promote the circulation and renewal of the washing water within the washing tub 1. Each lifting rib 23 has a number of mesh holes 231. These mesh holes 231 allow water and detergent to pass through, creating richer water flow and foam around the lifting ribs 23, allowing the washing water to penetrate deeper into the clothing fibers to remove stains and odors.

[0057] Preferably, the washing equipment is a washing machine or a washer-dryer combo.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.
