[0047] This application provides a pulsator washing machine, mainly used to dry the damp inner and outer drums after the washing machine has finished washing, thereby preventing bacteria from growing, causing odors, and creating secondary pollution due to the damp internal environment of the pulsator washing machine.

[0048] Figure 1 A complete view of a pulsator washing machine according to an embodiment of this application is shown. Figure 2 An assembly diagram of a pulsator washing machine according to an embodiment of this application is shown. Figure 3 An embodiment of this application is shown. Figure 2 The image shows a front view of a top-loading washing machine. Figure 4 An embodiment of this application is shown. Figure 3 The image shows a cross-sectional view (AA) of a top-loading washing machine.

[0049] refer to Figures 1 to 4 The pulsator washing machine provided in this application includes: a cabinet 1, an outer tub 2, an inner tub 3, a pulsator body 4, a hot air device 5, and a controller.

[0050] The outer tub 2 is located inside the housing 1 and primarily supports the inner tub 3. The inner tub 3 is located inside the outer tub 2 and primarily holds clothing. The impeller 4 is located at the bottom 31 of the inner tub and primarily rotates the inner tub 3, thereby agitating the water and clothing. The hot air device 5 is primarily used to heat the air, and the heated air is mainly used to promote the evaporation of water molecules. The controller is primarily used to coordinate the operation of the inner tub 3, the impeller 4, and the hot air device 5 to ensure thorough drying of both the inner and outer tubs.

[0051] In the pulsator washing machine provided in this application, the controller is configured as follows:

[0052] After the washing cycle is completed, the hot air device 5 is activated so that the hot air generated by the hot air device 5 enters the outer tub 1 and the inner tub 2.

[0053] In response to the start of operation of the hot air device 5, the inner tub 3 and the impeller 4 are controlled to rotate together in a manner that is first low speed and then high speed to dry the inner and outer tubs. When the inner tub 3 and the impeller 4 are controlled to rotate at low speed, they are used to preheat the water molecules attached to the inner and outer tubs. When the inner tub 3 and the impeller 4 are controlled to rotate at high speed, they are used to discharge the evaporated water molecules in the inner and outer tubs.

[0054] Specifically, after detecting a washing command, the controller executes the washing program to wash the clothes. Once the washing program is complete, the controller confirms that the washing is finished. At the end of the wash, the inner and outer drums of a top-loading washing machine are usually damp. If the user closes the top lid of the washing machine after removing the clothes, or if the outdoor environment is not conducive to the natural evaporation of water molecules, the internal environment of the top-loading washing machine will remain damp for a long time, which can easily lead to the growth of bacteria, unpleasant odors, and secondary pollution.

[0055] To prevent the internal environment of the pulsator washing machine from remaining damp for an extended period after the wash cycle, the controller activates the hot air device 5 upon detecting the completion of the wash cycle. Once activated, the hot air device 5 heats the air, generating hot air. This hot air, through convection, enters the outer tub 2 and inner tub 3, heating the water molecules adhering to the tub walls in contact with it.

[0056] It should be noted that hot air usually moves from bottom to top. Therefore, without external control, the hot air is not evenly distributed in the inner and outer barrels. This results in uneven heating of water molecules in different parts of the inner and outer barrels, which in turn leads to different drying effects in different parts of the inner and outer barrels, and some areas are difficult to dry completely.

[0057] Therefore, in order to ensure that the hot air is distributed as evenly as possible in the inner and outer drums, the controller responds to the start of the hot air device 5 by repeatedly controlling the inner drum 3 and the impeller 4 to rotate together in a low-speed-then-high-speed manner until the preset number of cycles is reached. For example, first control the inner drum 3 and the impeller 4 to rotate together at a speed of 40 rpm for 5 minutes, then control the inner drum 3 and the impeller 4 to rotate together at a speed of 600 rpm for 3 minutes, and repeat this cycle 5 times.

[0058] Low speed and high speed can be distinguished by preset speed thresholds. For example, the preset speed threshold for low speed is 60 rpm, and the preset speed threshold for high speed is 400 rpm. Therefore, if the speed is below 60 rpm, it is considered low speed; if the speed is above 400 rpm, it is considered high speed.

[0059] During each cycle, when the inner tub 3 and the impeller 4 rotate at low speed, the hot air, driven by both components, is evenly distributed across the inner and outer tubs. Furthermore, because the inner tub 3 and the impeller 4 rotate at low speeds, the hot air does not escape the washing machine too quickly, allowing it to remain in contact with all parts of the inner and outer tubs for a longer period. This ensures even and thorough preheating of the water molecules adhering to the tubs, promoting their evaporation.

[0060] During each cycle, when the inner tub 3 and the impeller 4 rotate at high speed, they will generate airflow from the bottom of the inner and outer tubs to the openings of the inner and outer tubs, thereby expelling the evaporated water molecules.

[0061] Considering that a small amount of unevaporated water molecules may remain inside the inner and outer drums after the first low-speed-to-high-speed rotation control, the low-speed-to-high-speed rotation control is repeated multiple times to fully dry the inner and outer drums.

[0062] In one embodiment, the inner tub 3 and the impeller 4 are controlled to rotate together in a manner that is first low speed and then high speed, cyclically a preset number of times, including:

[0063] During each cycle, the duration of low-speed rotation of the inner tub 3 and the impeller 4 is greater than the duration of high-speed rotation of the inner tub 3 and the impeller 4.

[0064] In this embodiment, considering that the time required to fully preheat water molecules is typically longer than the time required to expel evaporated water molecules, the duration of low-speed rotation of the inner tub 3 and impeller 4 during each cycle is longer than the duration of high-speed rotation. For example, during each cycle, the inner tub 3 and impeller 4 are first rotated at low speed for 5 minutes, and then at high speed for 3 minutes.

[0065] In one embodiment, the inner tub 3 and the impeller 4 are controlled to rotate together in a manner that is first low speed and then high speed, cyclically a preset number of times, including:

[0066] The duration of low-speed rotation of the inner tub 3 and impeller 4 during the first cycle is controlled to be longer than the duration of low-speed rotation of the inner tub 3 and impeller 4 during subsequent cycles.

[0067] The duration of high-speed rotation of the inner tub 3 and impeller 4 during the first cycle is controlled to be greater than the duration of high-speed rotation of the inner tub 3 and impeller 4 during subsequent cycles.

[0068] In this embodiment, considering that the humidity level inside the machine is lower in subsequent cycles compared to the first cycle, the amount of water molecules requiring preheating is less in subsequent cycles than in the first cycle. Therefore, the duration of low-speed rotation of the inner tub 3 and impeller 4 in the first cycle is controlled to be greater than the duration of low-speed rotation of the inner tub 3 and impeller 4 in subsequent cycles. For example, the duration of low-speed rotation of the inner tub 3 and impeller 4 in the first cycle is set to 5 minutes, and the duration of low-speed rotation of the inner tub 3 and impeller 4 in the second, third, and subsequent cycles is set to 3.5 minutes.

[0069] Similarly, compared to the amount of volatile water molecules that need to be discharged during the first cycle, the amount of volatile water molecules that need to be discharged during subsequent cycles is even less. Therefore, the duration of high-speed rotation of the inner tub 3 and impeller 4 during the first cycle will be controlled to be longer than the duration of high-speed rotation of the inner tub 3 and impeller 4 during subsequent cycles. For example, the duration of high-speed rotation of the inner tub 3 and impeller 4 during the first cycle will be set to 3 minutes, and the duration of high-speed rotation of the inner tub 3 and impeller 4 during the second, third, and subsequent cycles will all be set to 1.5 minutes.

[0070] In one embodiment, the inner tub 3 and the impeller 4 are controlled to rotate together in a manner that is first low speed and then high speed, cyclically a preset number of times, including:

[0071] For two adjacent cycles, the duration of low-speed rotation of the inner barrel 3 and impeller 4 in the previous cycle will be controlled to be greater than the duration of low-speed rotation of the inner barrel 3 and impeller 4 in the subsequent cycle.

[0072] For two adjacent cycles, the duration of high-speed rotation of the inner barrel 3 and impeller 4 in the previous cycle will be controlled to be greater than the duration of high-speed rotation of the inner barrel 3 and impeller 4 in the subsequent cycle.

[0073] In this embodiment, considering that the humidity level inside the machine is lower in the next cycle after each cycle, fewer water molecules need to be preheated and fewer water molecules need to be discharged in the next cycle. Therefore, for two adjacent cycles, the duration of low-speed rotation of the inner tub 3 and impeller 4 in the previous cycle is controlled to be greater than the duration of low-speed rotation of the inner tub 3 and impeller 4 in the subsequent cycle, and the duration of high-speed rotation of the inner tub 3 and impeller 4 in the previous cycle is controlled to be greater than the duration of high-speed rotation of the inner tub 3 and impeller 4 in the subsequent cycle.

[0074] For example, the duration of low-speed rotation of the inner tub 3 and impeller 4 during the first cycle is set to 5 minutes, the duration during the second cycle is set to 4 minutes, and the duration during the third cycle is set to 3 minutes. This process continues, gradually decreasing the duration of low-speed rotation.

[0075] Furthermore, the high-speed rotation time of the inner tub 3 and impeller 4 during the first cycle is set to 3.5 minutes, the high-speed rotation time of the inner tub 3 and impeller 4 during the second cycle is set to 2.5 minutes, and the high-speed rotation time of the inner tub 3 and impeller 4 during the third cycle is set to 1.5 minutes. And so on, continuously reducing the high-speed rotation time.

[0076] In one embodiment, the controller is further configured to:

[0077] After detecting that the inner and outer drums have been dried, the hot air device 5 is controlled to stop working, and the inner drum 3 and the impeller body 4 are controlled to stop rotating.

[0078] In this embodiment, after completing the preset number of cycles, the controller can confirm that the inner and outer drums have been dried, and then control the hot air device 5 to stop working, and control the inner drum 3 and the impeller 4 to stop rotating.

[0079] Figure 5 A flowchart of a control method performed by a controller in one embodiment of this application is shown.

[0080] refer to Figure 5 In one embodiment, after the washing cycle is complete, the controller activates the hot air device 5. Once the hot air device 5 starts operating, it heats the air to generate hot air, which then enters the inner and outer tubs.

[0081] In response to the start of operation of the hot air device 5, the controller first controls the inner tub 4 and the impeller 4 to rotate at a low speed for 5 minutes during the first cycle, so as to evenly and thoroughly preheat the water molecules adhering to all parts of the inner and outer tubs and promote the evaporation of water molecules. Then, the controller controls the inner tub 3 and the impeller 4 to rotate at a high speed for 3 minutes to discharge the evaporated water molecules in the inner and outer tubs.

[0082] Next, during the second cycle, the controller first controls the inner tub 3 and the impeller 4 to rotate at a low speed for 3.5 minutes to evenly and thoroughly preheat the remaining water molecules adhering to all parts of the inner and outer tubs, promoting the evaporation of the remaining water molecules. Then, the controller controls the inner tub 3 and the impeller 4 to rotate at a high speed for 1.5 minutes to discharge the evaporated remaining water molecules from the inner and outer tubs.

[0083] Then determine if the preset number of cycles has been reached. If not, continue to the next cycle—first rotate at low speed for 3.5 minutes, then rotate at high speed for 1.5 minutes. If the preset number of cycles has been reached, it means that the inner and outer drums are dry. Turn off the hot air device 5 and stop the inner drum 3 and impeller 4 from rotating.

[0084] In one embodiment, the pulsator washing machine further includes a drain valve. Upon detecting the completion of the wash cycle and before controlling the hot air device 5 to operate, the controller is further configured to:

[0085] The inner tub 3 and the impeller 4 are controlled to rotate at high speed together to throw out water droplets from the inner and outer tubs, and the drain valve is controlled to open to drain the water that has been thrown out.

[0086] In this embodiment, the pulsator washing machine is also equipped with a drain valve to drain the accumulated water. Considering that there are many clumps of water droplets attached to the inner and outer drums immediately after washing, these water droplets can be initially collected and drained to reduce the amount of water molecules that need to be preheated and drained during the subsequent drying process.

[0087] Therefore, after the controller detects that the washing is finished, before controlling the hot air device 5 to work, it controls the inner tub 3 and the impeller 4 to rotate at high speed together, which throws out the water droplets on the inner and outer tubs, forming water accumulation, and controls the drain valve to open and drain the water.

[0088] In one embodiment, the hot air device 5 is located at the bottom of the housing 1 to facilitate the upward movement of hot air.

[0089] Figure 6 An assembly diagram of a hot air device according to an embodiment of this application is shown. (Reference) Figure 2 and Figure 6 In one embodiment, the pulsator washing machine further includes: a frame 6 disposed on the top of the cabinet 1; the frame 6 is provided with a washing machine top cover for closing the cabinet 1; wherein, the hot air device 5 is disposed at the frame 6.

[0090] In this embodiment, the pulsator washing machine also has a frame 6 on the top of the cabinet 1, and a washing machine top cover for closing the cabinet 1 is provided on the frame 6.

[0091] Considering that the inner tub 3 and the impeller 4 will cause significant vibration at the bottom of the impeller washing machine when they rotate together, if the hot air device 5 is placed at the bottom of the impeller washing machine, it will be prone to problems due to vibration. Therefore, in this embodiment, the hot air device 5 is placed at the top of the impeller washing machine, specifically at the frame 6, thereby reducing the adverse effects of vibration on the hot air device 5.

[0092] Figure 7 A front view of a hot air device according to an embodiment of this application is shown. Figure 8An embodiment of this application is shown. Figure 7 Side view of the hot air device shown. Figure 9 An embodiment of this application is shown. Figure 8 A cross-sectional view of the hot air device shown.

[0093] refer to Figures 7 to 9 In one embodiment, the hot air device 5 includes: a volute-shaped housing 51; a heating element 52 and a centrifugal fan 53 disposed inside the housing 51; and a ventilation pipe 54 disposed at the opening end of the housing.

[0094] In this embodiment, the hot air device 5 includes: a housing 51, a heating element 52, a fan 53, and a ventilation pipe 54.

[0095] The housing 51 is volute-shaped to fit the curvature of the frame 6. Heating element 52 and centrifugal fan 53 are located inside the housing. When the heating element 52 operates, it generates heat, thus producing hot air around it. Simultaneously, the centrifugal fan 53 operates, expelling the hot air from the open end of the housing. A ventilation duct 54 is located at the open end of the housing, used to exhaust the hot air from the outlet 55 to the target location. Preferably, the centrifugal fan 53 is located inside the closed end of the housing, and the heating element 52 is located inside the open end of the housing.

[0096] refer to Figures 7 to 9 In one embodiment, the ventilation duct 54 is configured as a retractable corrugated duct.

[0097] In this embodiment, considering that the hot air device 5 is located at the top of the pulsator washing machine when it is installed in the frame 6, the ventilation pipe 54 will be subjected to a strong downward pulling force due to the vibration when the pulsator washing machine vibrates, which will make the ventilation pipe 54 easily damaged.

[0098] Therefore, in order to reduce the possibility of damage to the ventilation duct 54 due to vibration, the ventilation duct 54 is designed as a retractable corrugated pipe, thereby improving the structural safety of the ventilation duct 54.

[0099] refer to Figure 2 , Figures 7 to 9 In one embodiment, the hot air device 5 is provided with a ventilation pipe 54; the outer barrel 2 is provided with a vent 21; the ventilation pipe 54 is connected to the vent 21.

[0100] In this embodiment, the ventilation pipe 54 of the hot air device 5 is connected to the air vent 21 on the outer barrel body. Thus, the hot air generated by the hot air device 5 will first enter the interior of the outer barrel through the air vent 21 under the action of the ventilation pipe 54, and then enter the interior of the inner barrel through the gap between the outer barrel 2 and the inner barrel 3.

[0101] Furthermore, the outer tub 2 is provided with an air circulation pipe 22 on its wall. One end of the air circulation pipe 22 is connected to the vent 21, and the other end points to the bottom of the outer tub. Under the action of the air circulation pipe 22, the hot air generated by the hot air device 5 will first enter the bottom of the outer tub, and then enter the interior of the inner tub through the gap between the outer tub 2 and the inner tub 3.
