Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of washing equipment, and in particular relates to a foam generating device and a pulsator assembly of a washing equipment. BACKGROUND

[0002] In the field of modern household and industrial washing, washing equipment is an indispensable part of daily life, and its performance and efficiency directly affect the cleaning effect and service life of clothes and other items. When the traditional washing equipment is in operation, it usually achieves the cleaning purpose through mechanical stirring or the scouring action of water flow combined with the chemical cleaning ability of the detergent. However, in this process, the effective dissolution of the detergent is one of the key factors restricting the washing effect.

[0003] The existing washing equipment generally faces a common problem after the detergent is put in, that is, the dissolution process of the detergent is relatively slow and insufficient. This is mainly because after the detergent is added to the washing water, it needs a certain time to gradually dissolve and uniformly distribute in the washing liquid through water circulation and mechanical stirring. For some high-efficiency but poorly soluble detergents, if the washing time is set too short, it is likely that the detergent will not be completely dissolved before the washing cycle ends, thereby reducing the utilization rate of the detergent and affecting the final washing effect. In addition, the incompletely dissolved detergent may also remain on the clothes, causing the washed clothes to become hard, discolored, or produce an odor.

[0004] In order to improve the washing efficiency and effect, some improved washing equipment has appeared on the market, such as enhancing the stirring intensity, optimizing the water flow design, etc., but these methods often focus on physical level improvement, and have limited effect on promoting the rapid and sufficient dissolution of the detergent, and there is still a problem of insufficient dissolution of the detergent and insufficient bubbles.

[0005] Therefore, the present application is proposed. SUMMARY

[0040] At present, in the washing process of the existing washing equipment, due to the slow and continuous dissolution process of the detergent, if the washing time is insufficient, the detergent may not be fully dissolved before the washing is finished, and the residual detergent is easy to cause the clothes to turn yellow, etc., affecting the washing effect and the user's use experience.

[0041] Embodiment one

[0042] To solve the above problems, as shown in the Figs. 1 to 3 The foam generating device of the washing equipment provided by the embodiment includes:

[0043] The shell 1;

[0044] The foam generating assembly 2 is arranged in the shell 1, and the gap 21 through which the liquid can pass is arranged therein.

[0045] The openings on both sides of the gap 21 are inconsistent, and the liquid mixes to generate foam when passing through the gap 21.

[0046] In this embodiment, the foam generating device comprises a shell 1, and openings are arranged on both sides of the shell 1, which can be used as a path for inputting liquid into the shell 1 and discharging foam.

[0047] In this embodiment, the foam generating device further comprises a foam generating assembly 2 arranged at a central position inside the shell 1, which facilitates the mixing of liquid formed by the detergent and water to generate foam in the shell 1, and facilitates the discharge of foam.

[0048] Further, the gap 21 is arranged in the foam generating assembly 2, and the liquid entering the inside of the shell 1 from the outside can pass through the gap 21, and under the extrusion action of the gap 21, the detergent and water can be fully mixed to generate foam.

[0049] In this embodiment, the openings on both sides of the gap 21 of the foam generating assembly 2 are inconsistent, that is, the opening on one side of the gap 21 is slightly larger, and the opening on the other side is slightly smaller, so that the flow path of the liquid in the gap 21 is gradually reduced, so that the detergent and water are strongly turbulent mixed due to the change of flow rate and pressure when the liquid passes through the gap 21, thereby promoting the generation of foam, achieving the effect of fully dissolving the detergent, and improving the washing effect of the detergent.

[0050] In this embodiment, the gap 21 can be used to collect hair, lint and other impurities in the liquid, realize the preliminary filtration of the liquid, ensure the cleanliness of the foam, and improve the washing effect.

[0051] Therefore, the above foam generating device utilizes the principle of fluid dynamics by designing the structure of the gap 21 of the foam generating assembly 2, and realizes the mixing of liquid and the generation of foam without external power source, which facilitates to improve the dissolving effect of the detergent and improve the user experience. Moreover, the foam generating efficiency of the foam generating assembly 2 is high, the structure is simple, the manufacturing cost is low, and it is suitable for various liquid mixing and foaming needs, and has higher applicability.

[0052] In this embodiment, the shell 1 can be made of stainless steel material or plastic, which has good corrosion resistance and structural strength. The outer surface of the shell 1 can be provided with anti-slip texture, which facilitates the friction washing effect on the external clothes.

[0053] Embodiment Two

[0054] This embodiment is a further description of the above embodiment one.

[0055] like Figs. 1 to 3 As shown, in this embodiment, the housing 1 has a mixing chamber 11 for containing liquid, and the foam generating component 2 is disposed in the mixing chamber 11.

[0056] Specifically, a mixing chamber 11 is provided at the center of the housing 1. The mixing chamber 11 has sufficient volume to accommodate the liquid to be mixed and the generated foam. The shape and size of the mixing chamber 11 can be adaptively adjusted according to specific usage requirements to promote uniform mixing of the liquid and effective foam generation.

[0057] In this embodiment, the liquid enters the mixing chamber 11 and is dispersed and mixed through the gap 21 to generate foam.

[0058] Specifically, the foam generating component 2 is disposed within the mixing chamber 11. The foam generating component 2 has gaps 21 with inconsistent openings on both sides. When liquid enters the mixing chamber 11 and flows through the gaps 21, it is subjected to strong shear forces and turbulence, thereby being dispersed, mixed, and generating abundant foam, allowing the detergent to be fully dissolved.

[0059] Furthermore, the housing 1 is provided with an inlet channel 12 and an outlet channel 13 on both sides, and the ends of the inlet channel 12 and the outlet channel 13 are respectively connected to both sides of the mixing chamber 11. The foam generating component 2 is correspondingly arranged on the flow channel formed by the inlet channel 12 and the outlet channel 13.

[0060] Specifically, the liquid inlet channel 12 on one side of the housing 1 is used to introduce liquid, while the liquid outlet channel 13 on the other side serves as the outlet for the foam generated after the liquid is mixed. Alternatively, the liquid outlet channel 13 on one side of the housing 1 is used to introduce liquid, while the liquid inlet channel 12 on the other side serves as the outlet for the foam generated after mixing. The actual functions of the liquid inlet channel 12 and the liquid outlet channel 13 can be adjusted according to specific needs; for example, when the direction of water flow changes, the functions of the liquid inlet channel 12 and the liquid outlet channel 13 can be interchanged.

[0061] In this embodiment, external liquid flows into the mixing chamber 11 through the liquid inlet channel 12 and passes through the gap 21 to be mixed. The foam generated after mixing then flows out through the liquid outlet channel 13.

[0062] Specifically, multiple liquids are introduced into the mixing chamber 11 through the inlet channel 12. During the liquid flow, they first meet and initially mix. When the liquid flows through the foam generating component 2, it is subjected to strong shear force and turbulence, further agitating and mixing it evenly. Simultaneously, due to the presence of the gap 21, the gas in the liquid is broken into countless tiny bubbles, which tightly bind with the liquid to form foam. The mixed and foamed liquid flows out of the device through the drain channel 13 for subsequent use or treatment.

[0063] In this embodiment, by controlling the flow rate and pressure of the liquid inlet channel 12 or the liquid outlet channel 13, the precise proportioning and efficient mixing of different liquids in the mixing chamber 11 can be achieved.

[0064] In a further embodiment, the foam generating component 2 has a mixing structure 22, which is disposed within the mixing chamber 11.

[0065] Specifically, the mixing structure 22 is disposed within the mixing chamber 11, and the surface of the mixing structure 22 is provided with gaps 21. The openings on both sides of the gaps 21 are not uniform, gradually decreasing in size from one side to the other, forming a conical or wedge-shaped mixing channel. When the liquid flows through the gaps 21, it is subjected to strong shear forces and turbulence, thereby being dispersed and mixed uniformly.

[0066] Furthermore, the hybrid structure 22 is provided with a plurality of gaps 21 at intervals, and the gaps 21 have a first end 211 and a second end 212 along the direction of the flow channel. The opening of the first end 211 is larger than the opening of the second end 212. The first end 211 and the second end 212 are arranged in a cross pattern.

[0067] Specifically, to further improve the mixing effect, the mixing structure 22 is provided with a plurality of gaps 21 at intervals, and the gaps 21 are arranged in a cross pattern. Specifically, the first end 211 of each gap 21 (the end with the larger opening) is not on the same horizontal line as the second end 212 of the adjacent gap 21 (the end with the smaller opening), but rather they are staggered. This arrangement helps to enhance the fluidity and mixing uniformity of the liquid within the mixing chamber 11, allowing the liquid flowing in through the inlet channel 12 to mix more thoroughly and produce more and finer foam.

[0068] As described above, the foam generating component 2 has a compact structure and reasonable design, enabling efficient mixing and foaming of various liquids. Furthermore, the gaps 21 within the foam generating component 2 are uniform in size and rationally distributed, ensuring the quality and stability of the foam. The design of the inlet and outlet channels 13 improves the flexibility of liquid input and mixing efficiency, making it suitable for various application scenarios. Moreover, the foam generating device is easy to operate and maintain, reducing operating costs and maintenance difficulty.

[0069] Example 3

[0070] This embodiment is a further description of the above embodiments one and two.

[0071] like Figs. 1 to 3 As shown, in this embodiment, the mixing structure 22 is a baffle 23, which is vertically installed in the mixing chamber 11 of the housing 1, and the extending direction of the baffle 23 is consistent with the extending direction of the housing 1.

[0072] Specifically, the mixing structure 22 adopts the form of vertical baffles 23, which are vertically installed inside the mixing chamber 11 of the housing 1. The extending direction of the baffles 23 is consistent with the extending direction of the housing 1, that is, the baffles 23 are installed perpendicular to the bottom and top of the mixing chamber 11. The number, spacing and shape of the baffles 23 can be adjusted according to specific foam generation requirements.

[0073] More specifically, the baffle 23 is provided with multiple gaps 21, which are spaced apart or intersecting on the extended surface of the baffle 23. When liquid flows into the mixing chamber 11, it is blocked and guided by the baffle 23, generating a strong turbulence effect. This ensures that the liquid can only pass through the gaps 21, where it mixes and disperses, thereby promoting foam formation. Simultaneously, the turbulence effect of the baffle 23 helps to break the liquid into smaller droplets and increases the contact area between liquids, thus promoting mixing.

[0074] Furthermore, the gap 21 is a filter hole 24 penetrating the baffle 23, and the diameter of the filter hole 24 gradually decreases at both ends. Preferably, the filter hole 24 is a tapered hole.

[0075] Specifically, the baffle 23 has a large number of conical filter holes 24 distributed on it. The filter holes 24 extend from one side of the baffle 23 to the other, forming a channel for liquid to pass through. In particular, the diameter of the filter holes 24 gradually decreases at both ends, forming a conical structure. This allows the liquid to be subjected to gradually increasing shear force and turbulence when flowing through the filter holes 24, thus being broken into smaller droplets and coming into full contact with the gas to form foam, thereby improving the dissolution effect of the detergent.

[0076] In this embodiment, the plurality of filter holes 24 are arranged at intervals and cross each other along the extension direction of the baffle 23.

[0077] Specifically, to improve mixing efficiency, multiple conical filter holes 24 are arranged at intervals and crosswise along the extension direction of the baffle 23. This arrangement helps to increase the complexity and turbulence of the liquid flow, allowing liquids from different directions to be mixed more thoroughly within the mixing chamber 11.

[0078] As described above, the unique and efficient design of the conical filter orifice 24 significantly improves liquid mixing and foam generation quality. The cross-arranged filter orifice 24 increases the complexity and turbulence of liquid flow, resulting in more thorough and uniform mixing. Furthermore, it eliminates the need for complex moving mechanical parts, reducing energy consumption and noise, and improving the overall performance and lifespan of the device. Moreover, the structure is compact, easy to install and maintain, and suitable for various applications and liquid mixing needs.

[0079] Example 4

[0080] This embodiment is a further description of embodiments one to three described above.

[0081] In this embodiment, a pulsator assembly is also provided, including the foam generating device of the washing equipment as described above.

[0082] In this embodiment, the housing 1 is disposed on the impeller 3 of the impeller assembly, and the housing 1 and the impeller 3 are sealed to form a mixing chamber 11. The foam generating assembly 2 is disposed in the mixing chamber. When the impeller 3 rotates, liquid enters the mixing chamber 11 and passes through the gap 21 in the foam generating assembly 2. Under the mixing action of the gap 21, foam is generated.

[0083] Furthermore, the housing 1 is disposed on one side of the circumferential edge of the impeller 3, that is, the housing 1 is disposed on the outer peripheral edge of the impeller 3 and is tightly connected to the impeller 3. Disposing the foam generating device on the outer periphery of the impeller 3 facilitates the entry of water and other liquids into the mixing chamber 11 when the impeller 3 rotates. Simultaneously, it helps to optimize the structural layout of the impeller assembly in the washing equipment.

[0084] In this embodiment, the foam generating device has a bottom shell 25, which is mounted on the impeller 3. The bottom shell 25 serves as a supporting and mounting foundation for the fixed installation of the foam generating device.

[0085] Furthermore, the housing 1 and the bottom shell 25 are detachably connected to form a mixing chamber 11. The foam generating component 2 is disposed within the mixing chamber 11. Liquid enters the mixing chamber 11 and mixes through the gap 21 to form foam. At the same time, the gap 21 can initially filter impurities such as hair and lint in the liquid. When there are too many impurities, the housing 1 can be disassembled for cleaning, thus facilitating the cleaning and disassembly of the foam generating device. Moreover, the above structure is simple and easy to replace and maintain.

[0086] In this embodiment, one side of the circumferential edge of the impeller 3 is recessed inward to form a cavity 31, and the bottom shell 25 is embedded in the cavity 31.

[0087] Specifically, the impeller 3 has a cavity 31, which is formed by the inward indentation of a portion of the circumferential edge region of the impeller 3. The bottom shell 25 is embedded in the cavity 31 to achieve fixed installation of the foam generating device.

[0088] In this embodiment, the bottom shell 25 is installed in the cavity 31 of the impeller 3 by means of screws, buckles, etc., and is detachably connected to the impeller 3, which facilitates the cleaning or disassembly and maintenance of the foam generating device and improves convenience.

[0089] In this embodiment, an installation part 26 is provided on one side of the bottom shell 25, and the foam generating component 2 is disposed on the bottom shell 25. One end is snapped into the installation part 26, and the other end abuts against the side wall of the bottom shell 25, thereby realizing the fixed installation of the foam generating component 2.

[0090] Furthermore, the mounting part 26 is a boss structure with a groove in the middle. One end of the foam generating component 2 is engaged in the groove, which realizes a stable connection of the foam generating component 21 and makes the foam generating component 21 detachable for easy cleaning. Moreover, the above structure is simple and effectively optimizes the overall structural layout of the foam generating device.

[0091] Furthermore, to ensure the internal sealing of the device and prevent liquid leakage, sealing structures are provided between the housing 1 and the bottom shell 25, between the baffle 23 and the mounting part 26, and between the baffle 23 and the side wall of the bottom shell 25. These sealing structures can be gaskets, sealant, or O-rings, etc.

[0092] In this embodiment, the foam generating device is mounted on the impeller 3 and can serve as a lifting rib for the impeller assembly. This design combines foam generation with the lifting and tumbling action of the clothes, thereby continuously generating and distributing foam during the washing process and improving washing efficiency.

[0093] Specifically, a foam generating component 2 is provided inside the lifting rib. The foam generating component 2 has gaps 21 through which liquid can pass, and the two ends of these gaps 21 have inconsistent openings, forming conical or wedge-shaped channels. When the washing liquid flows through these gaps 21, it is subjected to shear force and turbulence, is broken into smaller droplets, and comes into full contact with air to form foam.

[0094] Specifically, the gaps 21 on the foam generating component 2 are arranged in a cross pattern or a special layout. This arrangement helps to increase the complexity and turbulence of the liquid flow, allowing the foam to be generated more fully and evenly distributed in the washing tub, thereby improving the foam generation efficiency and distribution uniformity.

[0095] During the washing process, the washing liquid enters the washing tub through the inlet pipe. The impeller 3 begins to rotate, driving the lifting ribs to move. As the washing liquid passes through the gap 21 of the foam generating component 2, it is broken into smaller droplets by shear force and turbulence, mixing with air to form foam. The foam is evenly distributed within the washing tub by the movement of the lifting ribs and makes full contact with the clothes, thereby improving washing efficiency and cleaning effect.

[0096] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
