[0040] Embodiment one:

[0041] Figures 1 to 7 The utility model discloses an embodiment one, and this embodiment includes outer bucket body 1, the bottom of outer bucket body 1 is equipped with the pulsator 2 for washing clothes, and the detachable dehydration barrel 3 is equipped above the pulsator 2, and the base for placing drive device 4 is equipped below outer bucket body 1, and the drive device 4 includes motor 41 and the output shaft 42 directly connected with motor 41, and the first transmission end 421 and the second transmission end 422 are equipped respectively on the output shaft 42, and the first transmission end 421 is used to be connected with the speed reducer 5 to make the speed reducer 5 output first rotation speed, and the speed reducer 5 transmission is connected to the pulsator 2, and the second transmission end 422 directly outputs second rotation speed and is used to connect dehydration barrel 3, and the first rotation speed is less than second rotation speed, when the dehydration barrel 3 is not installed, this embodiment is in first cleaning mode, and the pulsator 2 operates in first rotation speed in outer bucket body 1 alone, and the first cleaning mode is generally used to wash clothes, when this embodiment is in dehydration mode, the dehydration barrel 3 is installed to the second transmission end 422 to operate in second rotation speed.

[0042] First, in this embodiment, by being equipped with the first transmission end 421 and the second transmission end 422 on the output shaft 42 simultaneously, is used to control the rotation of the pulsator 2 and the dehydration barrel 3 respectively, under the cooperation of the speed reducer 5, can output a first rotation speed for cleaning simultaneously, and a second rotation speed for dehydration, compared with the low-speed drainage mode of the traditional semi-automatic pulsator 2 washing machine, the dehydration effect of this embodiment is better, saves the time of user, and improves the use experience of user.

[0043] Secondly, motor 41 and output shaft 42 are directly connected, need not indirectly connect through belt or other transmission device, improves the speed of second rotation speed, reduces the energy loss at the same time, further improves the dehydration effect.

[0044] Finally, thanks to the above structure, this embodiment does not need to set up belt or other transmission device, and also does not need to set up speed reduction clutch and other devices to carry out the mode switching of cleaning and dehydration, greatly reduces the part quantity of product, makes the product structure more simple and reliable, reduces the failure probability, simultaneously, production and assembly are simple, reduces production cost, and it is favorable to open up the market.

[0045] The first transmission end 421 of the output shaft 42 is connected to the speed reducer 5, which preferably comprises a speed reducer body 51 and an output end 52, so that the speed reducer 5 outputs a first rotating speed through the output end 52 and is drivingly connected to the pulsator 2, thereby entering the first cleaning mode, which is preferably used for washing clothes. In order to avoid damage to clothes caused by too fast rotating speed, the first rotating speed is preferably less than 400 rpm, for example, 300 rpm or 350 rpm. When the washing machine is in the first cleaning mode, there is a large amount of water in the outer barrel 1. If the first rotating speed is too fast, the washing machine may vibrate violently, produce noise or displace. By setting the first rotating speed to be less than 400 rpm, in combination with the damping device of the washing machine, the vibration can be effectively inhibited.

[0046] It should be noted that the speed reducer is a mature prior art, so the specific structure at the first transmission end 421 is not shown in the embodiment. The connection mode of the output shaft and the speed reducer includes but is not limited to spline, key groove and other connection modes. These embodiments all fall within the protection scope of the utility model.

[0047] The output shaft 42 is also provided with a second transmission end 422, which directly outputs a second rotating speed for connecting the dehydration barrel 3. When the user installs the dehydration barrel 3 to the second transmission end 422, the embodiment enters the dehydration mode. In order to make the dehydration effect better, the second rotating speed is preferably greater than 1000 rpm and less than 1400 rpm, for example, 1100 rpm or 1200 rpm. If the rotating speed is too low, the dehydration effect cannot be good. At the same time, the motor for washing machines on the market is mostly in the above-mentioned rotating speed range, which is convenient for manufacturers to purchase or users to maintain and replace the motor.

[0048] The embodiment also preferably has a first gear 423 cooperating with the pulsator 2 at the first transmission end 421, and the pulsator 2 is indirectly drivingly connected to the first transmission end 421 through the first gear 423. The second gear 424 cooperating with the dehydration barrel 3 is preferably arranged at the second transmission end 422, and the dehydration barrel 3 is drivingly connected to the second transmission end 422 through the second gear 424. In the art, the output shaft 42 and the speed reducer 5 are usually made of metal, and the pulsator 2 and the dehydration barrel 3 are usually made of plastic. In the working process, if the plastic material is directly connected with the metal material, the plastic material is easily abraded in the process of rotating work, which leads to poor cleaning and dehydration effect and increases the maintenance cost of the user. Therefore, the first gear 423 and the second gear 424 are preferably arranged to indirectly connect and drive, which has the effect of reducing abrasion and improving product quality.

[0049] Of course, in other embodiments, the material of the connection between the pulsator, the dehydration barrel and the first transmission end and the second transmission end can also be changed, and the first gear and the second gear are not provided, and are directly connected with the first transmission end and the second transmission end without being easy to wear, and these embodiments all fall within the protection scope of the utility model.

[0050] In order to facilitate the installation of the dehydration barrel 3, the second transmission end 422 is preferably arranged in the outer barrel body 1 in the embodiment, and the second transmission end 422 is covered by the middle protruding part of the pulsator 2, and the arrangement is to avoid that the clothes are wound into the second transmission end 422 and are damaged, and meanwhile, the middle of the pulsator 2 is provided with the protrusion 21, which can be used to connect other accessories, so that the washing machine enters other cleaning modes, and the specific use method will be embodied in the third embodiment.

[0051] As shown in Figure 4 and Figure 5 , the second transmission end 422 and the pulsator 2 form an installation cavity 6 for installing the dehydration barrel 3, and the first installation port 31 arranged at the bottom of the dehydration barrel 3 is put into the installation cavity 6 to complete the installation, and the dehydration mode of the embodiment is entered.

[0052] The shielding assembly 7 for shielding the second transmission end 422 in the first cleaning mode is also arranged in the outer barrel body 1, and the shielding assembly 7 is preferably arranged in the installation cavity 6 in the embodiment, and the shielding assembly 7 preferably comprises a shielding ring 71 matched with the installation cavity 6, and the shielding ring 71 is connected with a reset spring 72, when the dehydration barrel 3 is disassembled, the reset spring 72 drives the shielding ring 71 to shield the installation cavity 6, and the shielding ring 71 is matched with the pulsator 2 and is provided with a limiting assembly 73 for preventing the shielding ring 71 from being separated from the installation cavity 6, as shown in Figure 1 , when the dehydration barrel 3 is installed, the spring 72 is compressed, and the shielding ring 71 is lowered, so that the shielding assembly 7 does not need to be manually disassembled, and the operation is convenient, the shielding assembly 7 is arranged, and the clothes can be further prevented from being wound into the second transmission end 422 in the process of rotating cleaning, so that the clothes are not damaged, and meanwhile, the dirt, hair and the like in the clothes are easily taken out in the cleaning process, the shielding assembly 7 is arranged, and the dirt and hair can also be prevented from being accumulated in the installation cavity 6, so that the dehydration barrel 3 and the installation 6 have good transmission effect when the washing machine is used in the dehydration mode, the time for cleaning by the user is saved, and the use experience of the user is improved.

[0053] Of course, in other embodiments, the shielding cover and other structures can also be manually disassembled, and these embodiments all fall within the protection scope of the utility model.

[0054] In this embodiment, the speed reducer 5 is preferably arranged outside the outer drum 1, specifically outside the bottom of the outer drum 1, and a first shock pad 8 is arranged between the speed reducer 5 and the bottom of the outer drum 1, and the first shock pad 8 abuts against the outside of the bottom of the outer drum 1 and the upper side of the speed reducer 5 at the same time. The first shock pad 8 can reduce the shaking of the washing machine during operation, prevent displacement of the washing machine, and reduce noise.

[0055] Referring to Figure 3 , the speed reducer 5 preferably comprises a speed reducer shell 53, the first shock pad 8 is arranged above the speed reducer shell 53, and a fixing sheet 81 that cooperates with the speed reducer shell 53 is further arranged above the first shock pad 8. The first shock pad 8 is provided with a avoiding hole 81 for connecting the speed reducer shell 53 and the fixing sheet 81, and the speed reducer shell 53 and the fixing sheet 81 are connected through the avoiding hole 81. After the first shock pad 8 is clamped and fixedly connected with the speed reducer 5, the installation of the speed reducer 5 and the first shock pad 8 is more closely matched, the shock-absorbing effect is improved, and the first shock pad 8 and the speed reducer 5 can be combined in advance during assembly of the product, and then the whole is installed in the washing machine, thereby improving the assembly efficiency and reducing the production cost.

[0056] As shown in Figure 6 and Figure 7 , the bottom of the outer drum 1 is preferably inwardly recessed to form a groove 11, and a high platform 12 is formed on the inner side of the bottom of the outer drum 1.

In this way, water accumulated at the bottom of the outer drum 1 cannot contact the second connecting port 13, thereby improving the waterproof effect, making the product structure more compact, and reducing the product size.

[0057] A waterproof pad 9 for waterproofing is preferably arranged at the second connecting port 13, and the waterproof pad 9 is arranged between the second connecting port 13 and the first shock pad 8 to further improve the waterproof effect. Since the second connecting port only needs to accommodate the output shaft 42 and the output end 52, the size of the second connecting port is relatively small, and therefore the size of the waterproof pad 9 is also small, which has the advantage of saving production cost.

[0058] Embodiment Two:

[0059] Different from embodiment one, the speed reducer of this embodiment is arranged inside the dewatering drum 3, and a second shock pad is preferably arranged between the speed reducer 5 and the bottom of the dewatering drum 3.

In this way, a good shock-absorbing effect can also be achieved.

[0060] 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.
