Description

Technical Field

[0001] The invention belongs to the technical field of washing equipment, and in particular relates to a washing equipment. Background Art

[0002] Current washing machines typically use a motor connected to the bottom of the inner drum to spin the drum at high speed. The centrifugal force generated by this high speed causes the water in the laundry to escape due to the centrifugal force being greater than the adhesive force, and the water escapes through small holes in the inner drum, completing the dehydration process. The faster the spin, the greater the centrifugal force on the clothes. This method can remove most of the water from the clothes, but relying solely on centrifugal force can be ineffective and inefficient.

[0003] In order to further improve the air-drying effect, a blowing system consisting of a hair dryer is added to the side of the barrel for holding the clothes to be air-dried. The hair dryer generates high-speed convection air to remove moisture from the clothes, thereby achieving a better air-drying effect. However, since it requires an additional blowing system, additional installation space needs to be reserved, which increases product cost and increases power consumption, which is not conducive to energy saving.

[0004] Patent CN201120173223.X discloses a washing machine cover that is detachably connected to a spinner. The cover has a through-hole on which are mounted a plurality of blades angled relative to the cover surface. When a motor at the bottom of the spinner spins the spinner at high speed, the inclined blades on the cover force air outside the spinner into the spinner or force air inside out, creating intense convection within the spinner, accelerating drying and saving time.

[0005] The above-mentioned tub cover is for the spin drum of a twin-tub washing machine and needs to be installed each time it is used and removed after the spin cycle, which is cumbersome and has a high loss rate. Furthermore, when the tub cover is rotated, air in the space above the lid can flow downward into the spin drum, or air within the drum can flow upward. This leads to the following disadvantages: first, the circulating airflow path is long and must pass through bends in a narrow space, making it difficult to achieve high-speed air circulation; second, when the spin drum is spinning, the clothes mainly cling to the lower wall of the spin drum, and the circulating airflow mostly does not pass through the clothes. As a result, the air-drying effect of the above-mentioned patent is poor.

[0006] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Summary of the Invention

[0008] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: A washing device comprising: An inner barrel comprises an inner barrel body and a balance ring assembly fixedly mounted on the top of the inner barrel body; An outer barrel, which is sleeved on the outer side of the inner barrel; The balancing ring assembly comprises a balancing body, and a fan blade structure fixed at the lower end of the balancing body and capable of generating airflow when the inner barrel rotates; The inner barrel body is provided with a plurality of water-permeable holes and a plurality of first air vents for air flow to pass through, and the first air vents are located outside the fan blade structure.

[0009] In some embodiments of the present application, the fan blade structure can generate a downward and inward-inclined airflow when rotating with the inner barrel; the airflow in the inner barrel will gradually adjust its wind direction outward while moving downward, and reach the outside of the inner barrel through the water-permeable hole; then the airflow moves upward along the space between the outer barrel and the inner barrel, and then reaches the fan blade structure through the first air outlet, forming a cycle of dry airflow.

[0010] In some embodiments of the present application, the balancing ring assembly also includes a protective cover, and the protective cover, the inner barrel body and the balancing body are arranged to form a accommodating cavity for accommodating the fan blade structure, and the first air outlet is used to achieve gas communication between the accommodating cavity and the space outside the inner barrel.

[0011] In some embodiments of the present application, the gas in the outer space of the inner barrel enters the accommodating cavity through the first air vent, and the airflow through the first air vent is inclined upward in an inward direction.

[0012] In some embodiments of the present application, a second air vent is provided on the protective cover for achieving gas communication between the accommodating cavity and the inner barrel.

[0013] In some embodiments of the present application, the protective cover has an inner protective plate connected to the balance ring body, and a lower protective plate bent and extended outward along the lower end of the inner protective plate, and the second air outlet is opened on the lower protective plate.

[0014] In some embodiments of the present application, the lower protective plate is arranged to be tilted downward in an outward direction.

[0015] In some embodiments of the present application, the direction of the airflow outflowing from the second air outlet is set perpendicular to the plane where the lower protective plate is located.

[0016] In some embodiments of the present application, the fan blade structure has a plurality of fan blades circumferentially arranged at the lower end of the balancing body, and the fan blades have a first fan blade connected to the balancing body and a second fan blade bent and extended downward along the lower end of the first fan blade.

[0017] In some embodiments of the present application, the upper end of the fan blade is radially extended, and the lower end of the first fan blade is tilted downward in an outward direction.

[0018] In some embodiments of the present application, the first fan blade and the second fan blade are both flat plate structures.

[0020] In some embodiments of the present application, the angle between the first fan blade and the second fan blade is 140° to 150°.

[0021] In some embodiments of the present application, the first fan blades are arranged vertically.

[0022] In some embodiments of the present application, the lower end of the second fan blade is tilted downward in an outward direction.

Second, it reduces the number of user operations, as there is no need to place and remove the fan blade structure. When the inner tub rotates, the fan blade structure rotates, creating a circulating drying airflow inside and outside the inner tub. The gas between the inner and outer tubs passes through the first air vent, reaches the fan blade structure, and, driven by the fan blade structure, flows into the inner tub. Thereafter, it moves downward within the inner tub and gradually turns outward, reaching the outside of the inner tub through the water-permeable hole. The airflow then moves upward along the space between the outer and inner tubs. The provision of the first air vent facilitates smooth circulation of the drying airflow, ensuring the flow rate of the circulating airflow and achieving a better drying effect.

[0032] See also Figures 1-6 , is an embodiment of a washing device proposed by the present invention. A washing device 100 includes: an outer tub and an inner tub 10 arranged in a set. The inner tub 10 has an inner tub body 11 and a balancing ring assembly 12 fixed to the top of the inner tub body 11. The balancing ring assembly 12 has a balancing body 121 and a fan blade structure 122 fixed to the lower end of the balancing body 121. The fan blade structure 122 can generate airflow when the inner tub 10 rotates to achieve air drying of the clothes in the inner tub 10. The inner tub body 121 is provided with a plurality of water-permeable holes and a plurality of first air vents 111 for airflow. The first air vents 111 are located outside the fan blade structure 122.

[0033] In this embodiment, a fan blade structure 122 is fixedly provided at the lower end of the balancing body 121. When the inner tub 10 rotates, the fan blade structure 122 rotates together, generating an airflow that blows into the interior of the inner tub 10 or extracting the airflow inside the inner tub 10 and blowing it toward the first air outlet 111, so that the space between the inner tub 10 and the outer tub and the interior of the inner tub form a circulating air-drying airflow, which can be used to air-dry clothes. The fan blade structure 122 is provided at the lower end of the balancing body 121: first, it can reasonably utilize the space. The balancing body 121 is annular and has flat upper and lower end faces. The fan blade structure 122 is arranged in the space below the balancing body 121; second, it reduces the user's operating steps, and there is no need to place and remove the fan blade structure 122. When the inner tub 10 rotates, driving the fan blade structure 122 to rotate will form a circulating air-drying airflow inside and outside the inner tub 10.

[0034] In this embodiment, the fan blade structure 122 rotates together to generate an airflow toward the interior of the inner tub 10. The air between the inner tub 10 and the outer tub passes through the first air vent 111, reaches the fan blade structure 122, and, propelled by the fan blade structure 122, flows toward the interior of the inner tub 10. The air then moves downward within the inner tub 10. Due to the centrifugal force of the rotation and the circulating drying airflow, the airflow gradually turns outward, passing through the clothes and the water-permeable holes to reach the outside of the inner tub 10. The air then moves upward along the space between the outer and inner tubs 10, achieving a circulation of the drying airflow. The provision of the first air vent 111 facilitates smooth circulation of the drying airflow, ensures the flow rate of the circulating airflow, and achieves a better drying effect.

[0035] In some other embodiments of the present application, the airflow generated by the rotation of the fan blade structure 122 can also be set to blow between the inner barrel 10 and the outer barrel through the first air outlet 111.

[0036] In some embodiments of the present application, the fan blade structure 122 can generate a downward and inwardly inclined airflow when rotating with the inner tub 10. While moving downward, the airflow in the inner tub 10 is pushed by centrifugal force and the circulating airflow, gradually adjusting its direction outward and reaching the outside of the inner tub 10 through the water-permeable holes. The airflow then moves upward along the space between the outer tub and the inner tub 10, and then reaches the fan blade structure 122 through the first air outlet 111, forming a cycle of air-drying airflow. The rotation of the fan blade structure 122 generates a downward and inwardly inclined airflow. The inward inclination of the air-drying airflow when it is blown out from the fan blade structure 122 increases the time required for the airflow to turn, allowing the airflow to reach the lower space of the inner tub 10. As the airflow flows outward, it passes through the clothes blocking the inner side of the water-permeable holes, removing moisture from the clothes and enhancing the air-drying effect.

[0037] In some embodiments of the present application, the balancing ring assembly 12 further includes a protective cover 123. The protective cover 123, the inner barrel body 11, and the balancing body 121 enclose a housing chamber for accommodating the fan blade structure 122. The first air outlet 111 is used to achieve gas communication between the housing chamber and the space outside the inner barrel 10. The protective cover 123 is used to cover and protect the fan blade structure 122, preventing it from scratching the user or clothing. The protective cover 123 also helps to regulate the flow of gas in the housing chamber, ensure the direction of the airflow flowing out of the housing chamber, and ensure the flow rate of the circulating air-drying gas.

[0038] In some embodiments of the present application, the protective cover 123 can be configured to be integrally formed with the lower end of the balancing body 121; the protective cover 123 can also be configured as a separate component, and then the protective cover 123 is installed and fixed to the balancing body 121 and the inner barrel body 11.

[0039] In some embodiments of the present application, a second air vent 125 is provided on the protective cover 123 for communicating the gas in the accommodating chamber with the inner barrel 10. The space outside the inner barrel 10 is the space between the inner barrel 10 and the outer barrel. The gas in the space outside the inner barrel 10 enters the accommodating chamber through the first air vent 111. The airflow entering the first air vent 111 is the airflow flowing from the bottom to the top in the space outside the inner barrel 10. Therefore, the airflow passing through the first air vent 111 is tilted upward in the inward direction. The airflow entering the accommodating chamber is tilted upward in the inward direction, and the airflow out of the accommodating chamber is tilted downward and inward. That is, after the airflow passes through the fan blade structure 122, the flow direction is changed, thereby realizing the circulation of the air-dried gas.

[0040] In some embodiments of the present application, the protective cover 123 includes an inner protective plate 1231 connected to the balancing ring body 121, and a lower protective plate 1232 bent and extending outward from the lower end of the inner protective plate 1231. The second air outlet 125 is provided on the lower protective plate 1232. The bent structure of the protective cover 123 forms a receiving cavity between the inner barrel body 11 and the balancing body 121, and helps to increase the structural strength of the protective cover 123.

[0041] In some embodiments of the present application, the lower protective plate 1232 is tilted downward in the outward direction. Firstly, this allows the inner side of the gimbal assembly 12 to be thinner, or in other words, the height of the inner protective plate 1231 to be as small as possible, which facilitates the user's observation of the interior of the inner tub 10 after opening the upper cover and helps maximize the internal space of the inner tub 10. Secondly, the second air vent 125 is provided on the lower protective plate 1232, so that the second air vent 125 is tilted downward in the outward direction. The airflow outflowing from the second air vent 125 is tilted downward and inward, which facilitates smooth airflow. Preferably, the direction of the airflow outflowing from the second air vent 125 is perpendicular to the plane in which the second air vent 125 is located, or the direction of the airflow outflowing from the second air vent 125 is perpendicular to the plane in which the second air vent 125 is located.

[0042] In some embodiments of the present application, the angle between the lower protective plate 1232 and the horizontal plane is less than 30°. It is preferred to set the angle between the protective plate 1232 and the horizontal plane to be 3° to 25°. More preferably, the angle between the protective plate 1232 and the horizontal plane is set to be 5° to 15°.

[0043] In some embodiments of the present application, the blade structure 122 includes a plurality of blades 1220 circumferentially disposed at the lower end of the balancing body 121. The plurality of blades 1220 are evenly distributed circumferentially around the lower end of the balancing body 121. The blades 1220 and the lower end of the balancing body 121 may be integrally injection-molded. Alternatively, the blade structure 122 may include an annular fixing ring fixed to the lower end of the balancing body 121, with the blades 1220 fixed to the lower end of the fixing ring.

[0044] In some embodiments of the present application, the fan blade 1220 includes a first fan blade 1221 connected to the balancing body 121, and a second fan blade 1222 bent and extending downwardly along the lower end of the first fan blade 1221. The fan blade 1220 is a flat plate that is bent to form the first fan blade 1221 and the second fan blade 1222. This facilitates the first fan blade 1221 and the second fan blade 1222 to form a larger area for the air to be driven, thereby increasing the amount of air blown out and improving the flow rate of the drying airflow.

[0045] In some embodiments of the present application, the upper end of the fan blade 1220 is radially extended, that is, the upper end of the fan blade 1220 is arranged in the inward and outward directions. The lower end of the first fan blade 1221 is tilted downward in the outward direction. The first fan blade 1221 and the second fan blade 1222 are both flat plate structures. The lower end of the first fan blade 1221 is tilted, so that the second fan blade 1222 is tilted circumferentially on the basis of being tilted downward in the outward direction. All the fan blades 1220 have the same circumferential bending and tilting direction, that is, when the fan blade structure 122 rotates, all the fan blades 1220 push the gas in the same direction.

[0046] In some embodiments of the present application, the angle between first blade 1221 and second blade 1222 is 130° to 160°, preferably 140° to 150°. The lower end of second blade 1222 is tilted downward in an outward direction, which facilitates the tilted arrangement of lower protective plate 1232. Preferably, lower protective plate 1232 is arranged parallel to the lower end of second blade 1222.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
