Description

A semi-automatic pulsator washing machine with high-speed spin drying [Technical Field]

[0001] This utility model relates to a high-speed dehydration semi-automatic pulsator washing machine, belonging to the field of pulsator washing machines. [Background Technology]

[0002] Top-loading washing machines are a common household appliance. Traditional single-drum top-loading washing machines that combine washing and draining can only drain water because the rotation speed of the drain tub is limited by the rotation speed of the top roller. They cannot achieve the effect of high-speed spin-drying.

[0003] The improved fully automatic pulsator washing machine incorporates devices such as a reduction clutch, which, while achieving high-speed spin-drying, complicates the product's structure, increases the probability of malfunction, raises production costs, and indirectly increases the product's selling price.

[0004] [Utility Model Content]

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a high-speed dehydration semi-automatic pulsator washing machine.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A semi-automatic pulsator washing machine with high-speed spin-drying capability includes an outer tub, in which a washing pulsator and a detachable spin-drying tub are disposed. The machine also includes a drive device for rotating the pulsator and the spin-drying tub. The drive device includes a motor and an output shaft directly connected to the motor. The output shaft has a first transmission end and a second transmission end. The first transmission end is connected to a reducer to output a first speed, which is driven to the pulsator. The second transmission end directly outputs a second speed to connect to the spin-drying tub. The first speed is less than the second speed. In a first washing mode, the spin-drying tub is not installed, and the pulsator operates independently within the outer tub at the first speed. In a spin-drying mode, the spin-drying tub is installed at the second transmission end and operates at the second speed.

[0008] The beneficial effects of using this utility model are as follows:

[0009] Firstly, this invention features a first transmission end and a second transmission end on a single output shaft, which are used to control the rotation of the impeller and the spin-drying drum, respectively. With the help of a reducer, a first speed with a lower rotation speed can be output simultaneously for washing, and a second speed with a higher rotation speed can be output for spin-drying. Compared with the low-speed draining mode of traditional semi-automatic impeller washing machines, this invention has a better spin-drying effect, saves users' time, and improves the user experience.

[0010] Secondly, the motor and output shaft are directly connected, eliminating the need for indirect connection via belts or other transmission devices. This increases the speed of the second rotation speed, reducing energy loss and further improving the dehydration effect.

[0011] Finally, thanks to the above structure, this utility model does not require belts or other transmission devices, nor does it require deceleration clutches or other devices for switching between cleaning and dehydration modes. This greatly reduces the number of parts in the product, making the product structure simpler and more reliable, reducing the probability of failure. At the same time, it simplifies production and assembly, reduces production costs, and facilitates market expansion.

[0012] Preferably, the reducer is further provided with a first gear that cooperates with the impeller, and the impeller is indirectly connected to the first transmission end through the first gear.

[0019] Preferably, the shielding ring is equipped with a limiting component that cooperates with the impeller to prevent the shielding ring from dislodging from the mounting cavity.

[0020] Preferably, the reducer is located on the outside of the outer barrel, and a first shock-absorbing pad is provided between the reducer and the bottom of the outer barrel. The first shock-absorbing pad abuts against both the outer side of the bottom of the outer barrel and the upper side of the reducer.

[0021] Preferably, the reducer further includes a reducer housing, the first damping pad is disposed above the reducer housing, and a fixing plate that cooperates with the reducer housing is also disposed above the first damping pad. The first damping pad is provided with a clearance hole for connecting the reducer housing and the fixing plate.

[0022] Preferably, the bottom of the outer barrel has an inward groove, and the inner side of the bottom of the outer barrel has a raised platform, with the reducer located in the groove.

[0023] Preferably, the platform is provided with a second connection port for the output shaft and the first transmission end to pass through, and the second connection port is provided with a waterproof pad for waterproofing.

[0037] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0038] In the following description, terms such as “inner,” “outer,” “upper,” “lower,” “left,” and “right” that indicate orientation or positional relationship are used only for the convenience of describing the embodiments and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0039] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two main bodies at the connection point are not connected by an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0040] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0041] Example 1:

[0042] Figures 1 to 7 illustrate Embodiment 1 of this utility model. This embodiment includes an outer tub 1, with a washing impeller 2 at the bottom of the outer tub 1 and a detachable spin-dry tub 3 above the impeller 2. A base for placing a drive device 4 is located below the outer tub 1. The drive device 4 includes a motor 41 and an output shaft 42 directly connected to the motor 41. The output shaft 42 has a first transmission end 421 and a second transmission end 422. The first transmission end 421 is connected to a reducer 5 to output a first speed. The reducer 5 is connected to the impeller 2. The second transmission end 422 directly outputs a second speed to connect to the spin-dry tub 3. The first speed is less than the second speed. When the spin-dry tub 3 is not installed, this embodiment is in a first washing mode, where the impeller 2 operates independently within the outer tub 1 at the first speed. This first washing mode is generally used for washing clothes. When this embodiment is in spin-drying mode, the spin-dry tub 3 is installed to the second transmission end 422 and operates at the second speed.

[0043] Firstly, in this embodiment, a first transmission end 421 and a second transmission end 422 are simultaneously provided on an output shaft 42, which are used to control the rotation of the impeller 2 and the spin-dry tub 3, respectively. With the cooperation of the reducer 5, a first speed with a lower rotation speed can be output simultaneously for washing and a second speed with a higher rotation speed for spin-drying. Compared with the low-speed draining mode of the traditional semi-automatic impeller 2 washing machine, the spin-drying effect of this embodiment is better, saving users' time and improving the user experience.

[0044] Secondly, the motor 41 and the output shaft 42 are directly connected, eliminating the need for indirect connection via belts or other transmission devices. This increases the speed of the second rotation speed, reducing energy loss and further improving the dehydration effect.

[0045] Finally, thanks to the above structure, this embodiment does not require belts or other transmission devices, nor does it require deceleration clutches or other devices for switching between cleaning and dehydration modes. This greatly reduces the number of parts in the product, making the product structure simpler and more reliable, reducing the probability of failure. At the same time, it simplifies production and assembly, reduces production costs, and facilitates market expansion.

[0046] The first transmission end 421 of the output shaft 42 is connected to the reducer 5. The reducer 5 preferably includes a reducer body 51 and an output end 52, so that the reducer 5 outputs a first speed through the output end 52 and is transmitted to the impeller 2 to enter the first washing mode. The first washing mode is preferably used for washing clothes. In order to avoid damage to the clothes due to excessive speed, in this embodiment, the first speed is preferably set to less than 400 rpm, for example, 300 rpm or 350 rpm. When the washing machine is in the first washing mode, there is a lot of water in the outer tub 1. If the first speed is too fast, it may cause the washing machine to vibrate violently, generate noise or displacement. Setting the first speed to less than 400 rpm, in conjunction with the washing machine's shock absorption device, can effectively suppress vibration.

[0047] It should be noted that the reducer is a mature existing technology. Therefore, the specific structure of the first transmission end 421 is not shown in this embodiment. The connection method between the output shaft and the reducer includes, but is not limited to, spline, keyway and other connection methods. These implementation methods all fall within the protection scope of this utility model.

[0048] The output shaft 42 is also provided with a second transmission end 422. The second transmission end 422 directly outputs a second speed for connecting the spin-drying tub 3. When the user installs the spin-drying tub 3 to the second transmission end 422, this embodiment enters the spin-drying mode. In order to improve the spin-drying effect, this embodiment preferably sets the second speed to be greater than 1000 rpm and less than 1400 rpm, such as 1100 rpm or 1200 rpm. If the speed is too low, it will not achieve a good spin-drying effect. At the same time, most of the motors used in washing machines on the market are in the above-mentioned speed range, which makes it convenient for manufacturers to purchase or for users to repair or replace the motor.

[0049] In this embodiment, it is also preferred that a first gear 423 cooperating with the impeller 2 is provided at the first transmission end 421, and the impeller 2 is indirectly connected to the first transmission end 421 through the first gear 423; it is also preferred that a second gear 424 cooperating with the dehydration tank 3 is provided at the second connection end, and the dehydration tank 3 is connected to the second transmission end 422 through the second gear 424. In this field, the output shaft 42 and the reducer 5 are usually made of metal, while the impeller 2 and the dehydration tank 3 are usually made of plastic. During operation, if the plastic material is directly connected to the metal material, the plastic material is easily worn during rotation, resulting in poor cleaning and dehydration effects and increasing the user's maintenance costs. Therefore, this embodiment preferably provides the first gear 423 and the second gear 424 for indirect transmission, which has the effect of reducing wear and improving product quality.

[0050] Of course, in other embodiments, the materials of the connection between the impeller and the dehydration drum and the first transmission end and the second transmission end can be changed, and the first gear and the second gear can be omitted. They can be directly connected to the first transmission end and the second transmission end without being prone to wear. These embodiments all fall within the protection scope of this utility model.

[0051] To facilitate the installation of the spin-dry tub 3, in this embodiment, the second transmission end 422 is preferably located inside the outer tub 1. The second transmission end 422 is covered by the middle protrusion of the impeller 2. This arrangement is to prevent clothes from being caught in the second transmission end 422 and causing damage. At the same time, the impeller 2 has a protrusion 21 in the middle, which can be used to connect other accessories and enable the washing machine to enter other washing modes. The specific usage method will be shown in Embodiment 3.

[0052] As shown in Figures 4 and 5, an installation cavity 6 for installing the dehydration bucket 3 is formed between the second transmission end 422 and the impeller 2. The installation can be completed by placing the first installation port 31 at the bottom of the dehydration bucket 3 into the installation cavity 6, and the dehydration mode is entered in this embodiment.

[0053] Inside the outer tub 1, a shielding component 7 is provided for shielding the second transmission end 422 in the first washing mode. In this embodiment, the shielding component 7 is preferably located in the mounting cavity 6. The shielding component 7 preferably includes a shielding ring 71 that cooperates with the mounting cavity 6. The shielding ring 71 is connected to a return spring 72. When the dehydration tub 3 is disassembled, the return spring 72 drives the shielding ring 71 to shield the mounting cavity 6. The shielding ring 71 and the impeller 2 are provided with a limiting component 73 to prevent the shielding ring 71 from disengaging from the mounting cavity 6, as shown in Figure 1. When dehydration... When tub 3 is installed, spring 72 is compressed, and the shielding ring 71 moves down, eliminating the need for manual disassembly and reassembly of the shielding component 7, making operation convenient. The shielding component 7 further prevents clothes from being caught in the second transmission end 422 during the rotation washing process, avoiding damage to the clothes. At the same time, during the washing process, it is easy to bring out debris, hair, etc. from the clothes. The shielding component 7 can also prevent debris and hair from accumulating in the installation cavity 6, ensuring that the spin-drying tub 3 and the installation cavity 6 have good transmission effect when the washing machine is using the spin-drying mode, saving users cleaning time and improving the user experience.

[0054] Of course, in other embodiments, there may be structures such as manually detachable shields, and these embodiments all fall within the protection scope of this utility model.

[0055] In this embodiment, the reducer 5 is preferably located on the outside of the outer tub 1, specifically on the outside of the bottom of the outer tub 1. A first shock-absorbing pad 8 is provided between the reducer 5 and the bottom of the outer tub 1. The first shock-absorbing pad 8 abuts against both the outside of the bottom of the outer tub 1 and the upper side of the reducer 5. The first shock-absorbing pad 8 can reduce the shaking of the washing machine during operation, and has the functions of preventing the washing machine from shifting and reducing noise.

[0056] Referring to Figure 3, the reducer 5 preferably includes a reducer housing 53. The first shock-absorbing pad 8 is disposed above the reducer housing 5. A fixing plate 81 that cooperates with the reducer housing 53 is also provided above the first shock-absorbing pad 8. The first shock-absorbing pad 8 is provided with a clearance hole 81 for connecting the reducer housing 53 and the fixing plate 81. The reducer housing 53 and the fixing plate 81 are connected through the clearance hole 81. After the first shock-absorbing pad 8 is clamped, it is fixedly connected to the reducer 5. This arrangement not only allows the reducer 5 and the first shock-absorbing pad 8 to fit more closely and improve the shock absorption effect, but also allows the first shock-absorbing pad 8 to be pre-assembled with the reducer 5 during product assembly, and then the whole assembly is installed in the washing machine, which improves assembly efficiency and reduces production costs.

[0057] As shown in Figures 6 and 7, the bottom of the outer barrel 1 preferably forms an inward groove 11, and a raised platform 12 is formed on the inner side of the bottom of the outer barrel 1. The groove 11 is provided with a second connection port 13. The reducer 5 is located in the groove 11. The output shaft 42 and the output end 52 pass through the raised platform 12 through the second connection port 13. With this arrangement, water accumulated at the bottom of the outer barrel 1 is unlikely to come into contact with the second connection port 13, which improves the waterproof effect and makes the product structure more compact, reducing the product volume.

[0058] Preferably, a waterproof pad 9 is provided at the second connection port 13 for waterproofing. The waterproof pad 9 is located between the second connection port 13 and the first shock-absorbing pad 8 to further improve the waterproofing effect. At the same time, since the second connection port only needs to accommodate the output shaft 42 and the output end 52, the size of the second connection port is relatively small, so the size of the waterproof pad 9 is also small, which has the advantage of saving production costs.

[0059] Example 2:

[0060] Unlike Embodiment 1, the speed reducer in this embodiment is located inside the dehydration tank 3. Preferably, this embodiment has a second shock-absorbing pad, which is located between the speed reducer 5 and the bottom of the dehydration tank 3. The second shock-absorbing pad abuts against both the bottom of the speed reducer 5 and the top of the bottom of the outer tank 1. This arrangement can also achieve a better shock absorption effect.

[0061] A sealing ring is preferably provided between the bottom of the outer barrel 1 and the output shaft 42. Since water will accumulate at the bottom of the outer barrel 1 during operation, a sealing ring with good waterproof performance is provided to play a waterproof role.

[0062] Example 3:

[0063] As shown in Figure 8, based on the above embodiment, this embodiment also provides a column 10 that is detachably connected to the impeller 2. The column 10 is provided with a brush (not shown in the figure). The column 10 is installed on the protrusion 21 of the impeller 2. The spin-drying tub 3 is removed and the column 10 is installed to enter the second cleaning mode. The second cleaning mode can be used for washing shoes.

[0064] 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.
