[0035] Secondly, embodiments of this application provide a waste treatment device for performing the waste treatment method of the first aspect. The waste treatment device includes: a bin body configured to be rotatable and having a shredder inside; a cover body operably covering the top of the bin body, the cover body including a guide member, the guide member having an independent air inlet channel and an air outlet channel respectively communicating with the inner side of the bin body; an air supply assembly disposed on one side of the bin body, including a first fan and an air supply pipe, the air inlet end of the air supply pipe communicating with the air outlet end of the first fan, and the air outlet end communicating with the air inlet channel; a heating element disposed at the bottom of the bin body for heating the bin body, the air intake end of the first fan facing the heating element; and a control unit disposed on the outside of the bin body, the first fan and the heating element being communicatively connected to the control unit; wherein the control unit is configured to control the first fan to transport the hot airflow generated by the heating element through the air supply pipe and the air inlet channel to the inner side of the bin body, and the airflow inside the bin body is configured to be discharged through the air outlet channel.

[0036] Optionally, the waste disposal equipment also includes an exhaust assembly, which is located on one side of the bin.

[0042] This application provides a waste treatment method and a waste treatment device using the method. The waste treatment method includes: controlling the rotation of a bin; heating the bottom of the bin to generate a hot airflow; conveying the hot airflow from the top of the bin to the inside of the bin; and discharging the airflow from the inside of the bin from the top of the bin. The hot airflow generated by heating the bottom of the bin can transfer a portion of its heat to the inside of the bin through the bin. Conveying the hot airflow from the top of the bin to the inside of the bin, combined with the airflow transferred to the inside of the bin through the bin, effectively dries the kitchen waste inside the bin. This improves the utilization rate of the heat generated by the hot airflow, increases the drying efficiency of the waste inside the bin, removes moisture from the kitchen waste in a shorter time, improves the pulverization efficiency of the kitchen waste, thereby improving waste treatment efficiency and enhancing the user experience.

[0043] When the weight of the bin is less than or equal to the preset weight threshold, the supply of hot air to the top of the bin and the discharge of air from the inside of the bin will stop. When the weight of the bin is less than or equal to the preset weight threshold, it indicates that the drying of the moisture in the kitchen waste inside the bin is basically complete. Stopping the supply of hot air to the top of the bin and the discharge of air from the inside of the bin can reduce energy consumption and lower operating costs.

[0044] When the temperature inside the bin is greater than or equal to the preset temperature threshold and remains at that temperature for a preset duration, the supply of hot air to the top of the bin and the discharge of air from the inside of the bin will cease. When the temperature inside the bin is greater than or equal to the preset temperature threshold and remains at that temperature for a preset duration, it indicates that the drying of moisture in the food waste inside the bin has been underway for some time and is essentially complete. Stopping the supply of hot air to the top of the bin and the discharge of air from the inside of the bin reduces energy consumption and lowers operating costs.

[0045] When the humidity inside the bin is less than or equal to the preset humidity threshold, the supply of hot air to the top of the bin and the exhaust of air from the inside of the bin will cease. When the humidity inside the bin is less than or equal to the preset humidity threshold, it indicates that the drying of the food waste inside the bin is essentially complete. Stopping the supply of hot air to the top of the bin and the exhaust of air from the inside of the bin reduces energy consumption and lowers operating costs.

[0080] In some embodiments of this application, a waste disposal method is provided for a waste disposal device 100, the waste disposal device 100 including a bin 10 for containing waste, see reference. Figure 1 Waste disposal methods include:

[0081] S1. Control the rotation of barrel 10;

[0082] S2. Heating the bottom of the barrel 10 to generate hot airflow;

[0083] S3. The hot airflow is delivered from the top of the barrel 10 to the inside of the barrel 10;

[0084] S4. Expel the airflow inside the barrel 10 from the top of the barrel 10.

[0085] Waste processing equipment used to handle kitchen waste often contains food waste with high moisture content, making it difficult to pulverize. Therefore, the kitchen waste needs to be dried before subsequent cutting and pulverizing. Existing kitchen waste processing equipment typically dries the waste inside the bin by heating the bin to remove moisture, and then pulverizes the waste by rotating the bin. However, the heating element is usually located on the outside of the bin, and the heat generated during operation is transferred to the inside of the bin through the bottom and / or side walls. Even if the bin wall uses heat-conducting materials to improve heat transfer efficiency, some of the heat generated by the heating element still escapes and is lost. This results in low heat utilization and low drying efficiency of the heating bin drying method, affecting waste processing efficiency and user experience.

[0086] This application provides a waste treatment method and a waste treatment device 100 using the waste treatment method. The waste treatment method includes: S1, controlling the rotation of the bin 10; S2, heating the bottom of the bin 10 to generate hot airflow; S3, conveying the hot airflow from the top of the bin 10 to the inside of the bin 10; S4, discharging the airflow from the inside of the bin 10 from the top of the bin 10. The hot airflow generated at the bottom of the heating bucket 10 can transfer a portion of its heat to the inside of the bucket 10. This hot airflow, combined with the airflow transferred to the inside of the bucket 10, effectively dries the food waste inside the bucket 10. This improves the utilization rate of the heat generated by the hot airflow, increases the drying efficiency of the waste inside the bucket 10, removes moisture from the food waste in a shorter time, and improves the food waste pulverization efficiency. Ultimately, this improves waste processing efficiency and enhances the user experience.

[0087] In addition, in step S4, the airflow inside the barrel 10 is discharged from the top of the barrel 10, so that the moisture in the kitchen waste inside the barrel 10 carried by the airflow is discharged from the barrel 10, ensuring the proportion of hot airflow delivered to the barrel 10 and ensuring drying efficiency.

[0088] In one example, a hot airflow is delivered from the top of the barrel 10 to the inside of the barrel 10. The hot airflow flows from the top of the barrel 10 to the inside of the barrel 10, thereby purging and heating the airflow inside the barrel 10. Under the action of the incoming hot airflow, the airflow inside the barrel 10 flows towards the top of the barrel 10 and is discharged to the outside of the barrel 10, ensuring the drying effect of the kitchen waste inside the barrel 10.

[0089] It should be noted that, for example Figure 1 The order of steps S1 to S4 is not fixed and can be performed randomly. For example, the bottom of the barrel 10 can be heated first to generate hot airflow, and then the barrel 10 can be rotated. Alternatively, the airflow inside the barrel 10 can be discharged from the top of the barrel 10 first, and then the hot airflow can be transported from the top of the barrel 10 to the inside of the barrel 10 before rotating the barrel 10. Steps S3 and S4 can also be performed simultaneously, that is, while the hot airflow is transported from the top of the barrel 10 to the inside of the barrel 10, the airflow inside the barrel 10 is discharged from the top of the barrel 10. The specific order can be determined according to actual needs, ensuring that step S3 is performed after step S2.

[0090] In some embodiments, the waste disposal method further includes:

[0091] Obtain the weight of barrel 10;

[0092] When the weight of the barrel 10 is less than or equal to the preset weight threshold, the hot airflow to the top of the barrel 10 is stopped, and the airflow to the inside of the barrel 10 is stopped.

[0093] When the moisture content of the food waste inside the bin 10 is high, the overall weight of the bin 10 (i.e., the sum of the weight of the bin 10 itself and the weight of the food waste inside) is high. By heating the bottom of the bin 10 and delivering hot air from the top of the bin 10 to the inside, the food waste inside the bin 10 can be dried, removing moisture and thus reducing its weight. When the weight of the bin 10 is less than or equal to a preset weight threshold, it indicates that the moisture in the food waste inside the bin 10 has been largely removed, and the drying process is essentially complete. At this point, the delivery of hot air to the top of the bin 10 and the discharge of air from the inside of the bin 10 cease, thus stopping the drying process. This reduces energy consumption and lowers operating costs.

[0094] In some embodiments, the waste disposal method further includes:

[0095] Obtain the temperature inside the barrel 10;

[0096] When the temperature inside the barrel 10 is greater than or equal to the preset temperature threshold and remains at that temperature for a preset duration, the hot airflow to the top of the barrel 10 is stopped, and the airflow to the inside of the barrel 10 is stopped.

[0097] The heating of the bottom of the bucket 10 and the drying action of conveying hot air from the top of the bucket 10 to the inside of the bucket 10 can increase the temperature inside the bucket 10. When the temperature inside the bucket 10 is greater than or equal to the preset temperature threshold and is maintained for a preset time, it indicates that the drying process of the kitchen waste inside the bucket 10 has been carried out for a period of time. Maintaining the preset time indicates that the drying of the moisture in the kitchen waste inside the bucket is basically completed. Stop conveying hot air to the top of the bucket and stop the airflow from being discharged from the inside of the bucket to reduce energy consumption and operating costs.

[0098] In some embodiments, the waste disposal method further includes:

[0099] Obtain the humidity inside the barrel 10;

[0100] When the humidity inside the barrel 10 is less than or equal to the preset humidity threshold, the hot airflow to the top of the barrel 10 is stopped, and the airflow to the inside of the barrel 10 is stopped.

[0101] The food waste inside the bin 10 contains moisture, resulting in high humidity inside the bin 10. The drying process involves heating the bottom of the bin 10 and delivering hot air from the top of the bin 10 to the inside of the bin 10. Combined with the exhaust process of expelling the air from the inside of the bin 10 from the top of the bin 10, the moisture in the food waste can be removed, reducing the humidity inside the bin 10. When the humidity inside the bin 10 is less than or equal to a preset humidity threshold, it indicates that the drying process for the food waste is basically complete. At this point, the delivery of hot air to the top of the bin and the exhaust of air from the inside of the bin are stopped, which reduces energy consumption and lowers operating costs.

[0102] In some embodiments, the waste disposal device 100 includes a quiet mode, and the waste disposal method further includes:

[0103] In response to the control command corresponding to the quiet mode, the supply of hot air to the top of the barrel 10 is stopped, and the airflow discharged from the inside of the barrel 10 is stopped.

[0104] The actions of delivering hot air from the top of the bin 10 to the inside of the bin 10, and the actions of expelling air from the inside of the bin 10 to the top of the bin 10, combined with the rotation of the bin 10 to crush food waste, all generate considerable noise. In quiet mode, the delivery of hot air to the top of the bin 10 stops, and the expulsion of air from the inside of the bin 10 stops. Instead, the food waste inside the bin 10 is dried only by heating the bottom of the bin 10. This effectively reduces the noise generated during the waste disposal process and improves the user experience.

[0105] In some embodiments, refer to Figure 3 and Figure 9 The waste disposal equipment 100 also includes an air supply component 30 and a heating element 40. The air supply component 30 is located on one side of the bin 10 and includes a first fan 31 and an air supply pipe 32. The air inlet end of the air supply pipe 32 is connected to the air outlet end of the first fan 31, and the air outlet end is connected to the top of the inner side of the bin 10. The heating element 40 is located at the bottom of the bin 10.

[0106] Step S2, which involves heating the bottom of the barrel 10 to generate a hot airflow, includes controlling the heating element 40 to heat the barrel 10.

[0107] The waste disposal method also includes: controlling the first fan 31 to turn on, so as to transport the hot air generated by the heating element 40 through the air supply pipe 32 from the top of the bin 10 to the inside of the bin 10; controlling the first fan 31 to turn off, so as to stop the hot air supply to the top of the bin 10.

[0108] The first fan 31 is configured to transport the hot air generated by the heating element 40 to the inside of the barrel 10 through the air supply pipe 32. By controlling the opening and closing of the first fan 31, the transmission of the hot air generated by the heating element 40 to the inside of the barrel 10 can be switched on and off. The structure is simple and stable, ensuring the stability of the transmission of the hot air to the top of the barrel 10.

[0109] The first fan 31 delivers airflow into the inner side of the barrel 10 through the air supply pipe 32. The airflow flows from the top of the barrel 10 to the bottom of the inner side of the barrel 10, thereby sweeping the airflow at the bottom of the inner side of the barrel 10. This causes the airflow at the bottom of the inner side of the barrel 10 to carry moisture and flow towards the top of the barrel 10, and then exit the barrel 10 through the top of the barrel 10. Thus, by controlling the opening and closing of the first fan 31, the opening and closing of the airflow exiting the barrel 10 can be achieved.

[0110] In some embodiments, refer to Figure 4 , Figure 8 , Figure 9 The waste disposal equipment 100 also includes an exhaust assembly 50, which is located on one side of the bin 10 and includes a second fan 51 and an exhaust pipe 52. The air inlet of the exhaust pipe 52 is connected to the top of the inner side of the bin 10, and the air outlet is connected to the air suction end of the exhaust pipe 52.

[0111] The waste disposal method also includes: controlling the second fan 51 to turn on so that the airflow inside the bin 10 is discharged from the top of the bin 10; controlling the second fan 51 to turn off so as to stop the airflow from being discharged from the inside of the bin 10.

[0112] The second fan 51 is configured to discharge the airflow inside the barrel 10 from the top of the barrel 10 through the exhaust pipe 52. By controlling the opening and closing of the second fan 51, the discharge of airflow from the inside of the barrel 10 can be started and stopped.

[0113] In some embodiments, the first fan 31 and the second fan 51 are respectively communicatively connected to the control unit 80. The control unit 80 is configured to control the rotational speed of the first fan 31 and the second fan 51 to control the air supply speed of the first fan 31 in delivering hot air to the inside of the barrel 10 through the air supply pipe 32, and to control the air exhaust speed of the second fan 51 in discharging air from the inside of the barrel 10 through the exhaust pipe 52. The control unit 80 is also configured to shut down the first fan 31 and / or the second fan 51 to stop delivering hot air to the inside of the barrel 10 and / or stop discharging air from the inside of the barrel 10.

[0114] The design of the second fan 51 and the exhaust pipe 52 in the exhaust assembly 50 allows the second fan 51 to discharge the airflow inside the bucket 10 through the exhaust pipe 52, thereby increasing the discharge speed of the airflow inside the bucket 10. Combined with the structural design of the first fan 31 to transport the hot airflow generated by the heating element 40 to the inside of the bucket 10 through the air supply pipe 32, the flow speed of the airflow inside the bucket 10 can be accelerated, thereby improving the drying efficiency of the moisture in the kitchen waste inside the bucket 10.

[0115] In some embodiments, refer to Figure 4 , Figure 8 , Figure 9 The air supply assembly 30 and the exhaust assembly 50 are arranged at intervals along the circumferential direction of the barrel 10 and are spaced apart from the side wall of the barrel 10. This arrangement ensures that the air supply assembly 30 and the exhaust assembly 50 are close to the barrel 10 without interfering with the rotation of the barrel 10, thereby improving space utilization, enhancing the compactness of the overall structure, shortening the air supply and exhaust paths, and ensuring drying efficiency.

[0116] In some embodiments, the first fan 31 and the second fan 51 are turned on or off synchronously, so that steps S3 and S4 are performed or stopped synchronously.

[0117] In some embodiments, refer to Figure 9 , Figure 15 The air supply assembly 50 also includes a second support 53, which includes a second inlet 531 and a second outlet (not shown in the figure) that are connected to each other. The second inlet 531 is configured to be opposite to the suction end of the second fan 51, and the second outlet is connected to the air outlet of the exhaust pipe 52. The second fan 53 discharges the airflow inside the barrel 10 to the outside of the barrel 10 through the second support 53 and the exhaust pipe 52.

[0118] In some embodiments, refer to Figure 15 The exhaust pipe 52 extends along the height of the barrel 10. The side of the exhaust pipe 52 facing the outer wall of the barrel 10 is curved, corresponding to the shape of the outer wall of the barrel 10, so as to shorten the distance between the exhaust pipe 52 and the barrel 10 without interfering with the rotation of the barrel 10 and improve the space utilization.

[0119] In some embodiments, the barrel 10 has a first rotational speed and a second rotational speed, wherein the first rotational speed is less than the second rotational speed; step S1 of controlling the rotation of the barrel 10 further includes the following steps: obtaining the weight of the barrel 10; when the weight of the barrel 10 is greater than a preset weight threshold, controlling the barrel 10 to rotate at the first rotational speed; when the weight of the barrel 10 is less than or equal to the preset weight threshold, controlling the barrel 10 to rotate at the second rotational speed.

[0120] When the moisture content of the food waste inside the bin 10 is high, the overall weight of the bin 10 (i.e., the sum of the weight of the bin 10 itself and the weight of the food waste inside) is high. If the bin 10 rotates at a high speed, the pulverization effect on the food waste will be poor. Therefore, when the weight of the bin 10 is greater than the preset weight threshold, the bin 10 is controlled to rotate at a lower first speed. By heating the bottom of the bin 10 and conveying hot air from the top of the bin 10 to the inside of the bin 10, the food waste inside the bin 10 can be dried, removing the moisture from the food waste, thereby reducing the weight of the food waste and the weight of the bin 10. Therefore, when the weight of the bin 10 is less than or equal to the preset weight threshold, it indicates that the moisture in the food waste inside the bin 10 has been basically removed. Controlling the bin 10 to rotate at a relatively higher second speed can improve the pulverization effect on the food waste and improve the waste treatment efficiency.

[0121] In some embodiments, step S1 of controlling the rotation of the barrel 10 further includes the following steps: obtaining the temperature inside the barrel 10; when the temperature inside the barrel 10 is less than a preset temperature threshold, controlling the barrel 10 to rotate at a first rotation speed; when the temperature inside the barrel 10 is greater than or equal to the preset temperature threshold and is maintained for a preset time, controlling the barrel 10 to rotate at a second rotation speed.

[0122] Heating the bottom of the bucket 10 and conveying hot air from the top of the bucket 10 to the inside of the bucket 10 during the drying process can increase the temperature inside the bucket 10. When the temperature inside the bucket 10 is less than a preset temperature threshold, it indicates that the temperature inside the bucket 10 is relatively low, and the drying effect on the moisture in the food waste is not significant. If the bucket 10 rotates at a higher speed, the pulverization effect on the food waste will be poor. Therefore, the bucket 10 is controlled to rotate at a relatively lower first speed to reduce energy consumption. When the temperature inside the bucket 10 is greater than or equal to the preset temperature threshold and is maintained for a preset time, it indicates that the drying process of the food waste inside the bucket 10 has been carried out for a period of time. Maintaining the preset time indicates that the drying of the moisture in the food waste inside the bucket is basically completed. Controlling the bucket 10 to rotate at a relatively higher second speed can improve the pulverization effect on the food waste and improve the waste treatment efficiency.

[0123] In some embodiments, step S1 of controlling the rotation of the barrel 10 further includes the following steps: obtaining the humidity inside the barrel 10; when the humidity inside the barrel 10 is greater than a preset humidity threshold, controlling the barrel 10 to rotate at a first rotation speed; and when the humidity inside the barrel 10 is less than or equal to the preset humidity threshold, controlling the barrel 10 to rotate at a second rotation speed.

[0124] The food waste inside the bin 10 contains moisture, resulting in high humidity. If the bin 10 rotates at a high speed, the pulverization effect on the food waste will be poor. Therefore, when the humidity inside the bin 10 is greater than the preset humidity threshold, the bin 10 is controlled to rotate at a relatively low first speed to reduce energy consumption. When the humidity inside the bin 10 is less than or equal to the preset humidity threshold, it indicates that the drying process of the food waste is basically complete. Controlling the bin 10 to rotate at a relatively high second speed can improve the pulverization effect of the food waste and improve the waste treatment efficiency.

[0125] In some embodiments, step S1 of controlling the rotation of the bin 10 further includes the following step: the waste disposal device 100 includes a quiet mode, and in response to a control command corresponding to the quiet mode, the bin 10 is controlled to rotate at a first rotational speed. In the quiet mode, controlling the bin 10 to rotate at a relatively low first rotational speed can reduce the noise generated during the crushing of kitchen waste and improve the user experience.

[0126] In some embodiments of this application, a waste treatment device 100 is also provided for performing the waste treatment method as described above, with reference to... Figures 3-5 , Figure 10 The waste disposal equipment 100 includes: a bin 10, a cover 20, an air supply component 30, a heating element 40, and a control unit 80.

[0127] The bin 10 is configured to rotate and contains a shredder 11. Specifically, the bin 10 is used to hold food waste, and the rotation of the bin 10 drives the shredder 11 to shred the food waste.

[0128] Reference Figures 2-4 The lid 20 is detachably mounted on top of the barrel 10, as shown in the reference. Figures 6-8 The cover 20 includes a flow guide 21, as shown in the reference. Figures 10-11 The guide component 21 is provided with an air inlet channel 211 and an air outlet channel 212 that are independent of each other and are respectively connected to the inside of the barrel 10.

[0129] Reference Figure 3 , Figure 8 , Figure 9 The air supply assembly 30 is located on one side of the barrel 10 and includes a first fan 31 and an air supply pipe 32. The air inlet end of the air supply pipe 32 is connected to the air outlet end of the first fan 31, and the air outlet end is connected to the air inlet channel.

[0130] The heating element 40 is located at the bottom of the barrel 10 and is used to heat the barrel 10. The suction end of the first fan 31 faces the heating element 40.

[0131] Reference Figure 5 The control unit 80 is located on the outside of the barrel body 10, as shown in the reference. Figure 17The first fan 31 and the heating element 40 are respectively communicatively connected to the control unit 80. In one example, refer to... Figure 5 The control unit 80 is shaped like a board, such as a circuit board.

[0132] The control unit 80 is configured to control the first fan 31 to deliver the hot air generated by the heating element 40 through the air supply pipe 32 and the air inlet channel 211 to the inside of the barrel 10, and the air in the barrel 10 is configured to be discharged through the air outlet channel 212.

[0133] This application provides a waste disposal device 100, including a bin 10, which is rotatable and has a shredder 11 inside. A cover 20 is operably installed on the top of the bin 10, and the cover 20 includes a guide 21. The guide 21 has an independent air inlet channel 211 and an air outlet channel 212 that are respectively connected to the inside of the bin 10. An air supply assembly 30 is disposed on one side of the bin 10, and the air supply assembly 30 includes a first... The fan 31 and the air supply duct 32 are connected. The air inlet end of the air supply duct 32 is connected to the air outlet end of the first fan 31, and the air outlet end is connected to the air inlet channel 211. The heating element 40 is used to heat the barrel 10 and is arranged opposite to the air intake end of the first fan 31. The first fan 31 is configured to transport the hot air generated by the heating element 40 to the inside of the barrel 10 through the air supply duct 32 and the air inlet channel 211. The airflow inside the barrel 10 is configured to pass through the air outlet channel 211. The design of the discharge bin 12, the guide pipe 21, and the air supply assembly 30 allows the first fan 31 to transport the hot airflow generated by the heating element 40 during the heating of the bin 10 through the air inlet channel of the guide pipe 21 located at the top of the bin 10 to the inside of the bin 10. This allows a portion of the heat generated by the heating element 40 during operation to be transferred to the inside of the bin 10 through the bottom wall and / or side wall of the bin 10. Most of the remaining heat is transported to the inside of the bin 10 through the air inlet channel 211 on the first fan 31, the air supply pipe 32, and the guide pipe 30, from the top of the bin 10 to the inside of the bin 10. This ensures that most of the heat generated by the heating element 40 is used to dry the moisture in the kitchen waste inside the bin 10, improving the utilization rate of the hot airflow generated by the heating element 40, improving the drying efficiency of the waste inside the bin 10, thereby improving waste treatment efficiency and enhancing the user experience.

[0134] The first fan 31 delivers airflow into the inner side of the barrel 10 through the air supply pipe 32 and the air inlet channel 211 on the guide component 30. The airflow flows from the top of the barrel 10 to the bottom of the inner side of the barrel 10, thereby sweeping the airflow at the bottom of the inner side of the barrel 10. This causes the airflow at the bottom of the inner side of the barrel 10 to carry moisture and flow towards the top of the barrel 10, and then be discharged to the outside of the barrel 10 through the air outlet channel 212, ensuring the drying effect of the kitchen waste inside the barrel 10.

[0135] In addition, the structure design of the cover 20 being openable and covering the top of the bin 10 means that when users need to dispose of kitchen waste, they only need to open the cover 20 to put the kitchen waste into the bin 10, close the cover 20, and then start the waste disposal equipment 100 to process the kitchen waste as needed, which is convenient to use.

[0136] In some embodiments, refer to Figure 4 , Figure 5 , Figure 9 The waste disposal equipment 100 also includes an exhaust assembly 50, which is disposed on one side of the bin 10. The air supply assembly 30 and the exhaust assembly 50 are arranged at intervals along the circumferential direction of the bin 10 and are spaced apart from the side wall of the bin 10. The exhaust assembly 50 includes a second fan 51 and an exhaust pipe 52. The air inlet end of the exhaust pipe 52 is connected to the air outlet channel 212, and the air outlet end is connected to the air intake end of the second fan 51. The second fan 51 is communicatively connected to the control unit 80. The control unit 80 is configured to control the second fan 51 to discharge the airflow inside the bin 10 through the air outlet channel 212 and the exhaust pipe 52.

[0137] The design of the second fan 51 and the exhaust pipe 52 in the air supply assembly 30 enables the control unit 80 to control the second fan 51 to discharge the airflow inside the bucket 10 through the second air outlet 2122 via the exhaust pipe 52, thereby increasing the discharge speed of the airflow inside the bucket 10. Combined with the structural design of the first fan 31 cooperating with the air supply pipe 32 to transport the hot airflow generated by the heating element 40 to the inside of the bucket 10 through the first air inlet 2111, the flow speed of the airflow inside the bucket 10 can be accelerated, thereby improving the drying efficiency of the moisture in the kitchen waste inside the bucket 10.

[0138] The air supply component 30 and the air exhaust component 50 are arranged at intervals along the circumferential direction of the barrel 10 and are spaced apart from the side wall of the barrel 10. This structural design allows the air supply component 30 and the air exhaust component 50 to be close to the barrel 10 without interfering with the rotation of the barrel 10, thereby improving space utilization, enhancing the compactness of the overall structure, shortening the air supply and exhaust paths, and ensuring drying efficiency.

[0139] In some embodiments, refer to Figure 17 The waste disposal equipment 100 also includes a weighing sensor 81 for acquiring the weight of the bin 10. The weighing sensor 81 is located at the bottom of the bin 10 and is communicatively connected to the control unit 80. The control unit 80 is configured to control the opening and closing of the first fan 31 and the second fan 51 based on the weight data of the bin 10 acquired by the weighing sensor 81, and to control the rotation speed of the first fan 31 and the second fan 51 when they are on, so as to ensure the drying efficiency of the kitchen waste inside the bin 10.

[0140] In some embodiments, when the weight of the bucket 10 is greater than a preset weight threshold, the bucket 10 is controlled to rotate at a first rotation speed, and when the weight of the bucket 10 is less than or equal to the preset weight threshold, the bucket 10 rotates at a second rotation speed, wherein the first rotation speed is less than the second rotation speed.

[0141] In some embodiments, refer to Figure 17 The waste disposal equipment 100 also includes a temperature sensor 82 for acquiring the temperature inside the bin 10. The temperature sensor 82 is located inside the bin 10 and is communicatively connected to the control unit 80. Based on the temperature data detected by the temperature sensor 82, the control unit 80 is configured to control the opening and closing of the first fan 31 and the second fan 51, and to control the rotation speed of the first fan 31 and the second fan 51 when they are on, so as to ensure the drying efficiency of the kitchen waste inside the bin 10.

[0142] In some embodiments, when the temperature inside the barrel 10 is less than a preset temperature threshold, the barrel 10 is controlled to rotate at a first rotation speed. When the temperature inside the barrel 10 is greater than or equal to the preset temperature threshold and is maintained for a preset duration, the barrel 10 is controlled to rotate at a second rotation speed, wherein the first rotation speed is less than the second rotation speed.

[0143] In some embodiments, refer to Figure 17 The waste disposal equipment 100 also includes a humidity sensor 83 for acquiring the humidity inside the bin 10. The humidity sensor 83 is located inside the bin 10 and is communicatively connected to the control unit 80. Based on the humidity data detected by the humidity sensor 83, the control unit 80 is configured to control the opening and closing of the first fan 31 and the second fan 51, and to control the rotation speed of the first fan 31 and the second fan 51 when they are on, so as to ensure the drying efficiency of the kitchen waste inside the bin 10.

[0144] In some embodiments, when the humidity inside the barrel 10 is greater than a preset humidity threshold, the barrel 10 is controlled to rotate at a first rotation speed, and when the humidity inside the barrel 10 is less than or equal to the preset humidity threshold, the barrel 10 is controlled to rotate at a second rotation speed, wherein the first rotation speed is less than the second rotation speed.

[0145] In some embodiments, refer to Figure 3 , Figure 4 and Figure 17The waste disposal equipment 100 also includes a control panel 84, which is located on one side of the bin 10 and communicatively connected to the control unit 80. The control panel 84 is configured to receive control commands corresponding to the quiet mode. In response to the control commands corresponding to the quiet mode, the control unit 80 controls the bin 10 to rotate at the first speed via the motor 85, and controls the first fan 31 to shut off to stop supplying hot airflow to the top of the bin 10, and controls the second fan 51 to shut off to stop the airflow exhausting from the inside of the bin 10. Thus, the control unit controls the motor 85 to rotate at a relatively low first speed, and both the first fan 31 and the second fan 51 are shut off, so that the waste disposal equipment 100 is in a low-noise quiet mode, improving the user experience.

[0146] In some embodiments, the waste disposal device 100 further includes a motor 85 for driving the bin 10 to rotate. The motor 85 is disposed at the bottom of the bin 10 and connected to the bin 10. The motor 85 is communicatively connected to a control unit 80, which is configured to control the motor 85 to switch between a first speed and a second speed.

[0147] In some embodiments, the control panel 84 is provided with a first button (not shown in the figure) corresponding to the quiet mode. When the user presses the first button, the waste disposal device 100 enters the quiet mode.

[0148] In some embodiments, the control panel 84 is also provided with buttons corresponding to other modes, such as a fast mode. In the fast mode, the control unit 80 controls the fan 85 to make the barrel 10 rotate at a second speed, and controls both the first fan 31 and the second fan 51 to be turned on.

[0149] In some embodiments, the control unit 80 is configured to communicate with a user terminal, enabling the user to send control commands to the control unit 80 via the user terminal (e.g., an app or application).

[0150] In some embodiments, refer to Figure 8 The cover 20 also includes a partition 22. (See reference...) Figures 10-11 The guide member 21 has a cavity 210 inside, as shown in the reference. Figure 11A partition 22 is disposed in the cavity 210, dividing the cavity 210 into a first partition 2101 and a second partition 2102 that are spaced apart and independent of each other. An air inlet channel 211 is disposed in the first partition 2101, and an air outlet channel 212 is disposed in the second partition 2102. The partition 22 in the cavity 210 divides the cavity 210 into the first partition 2101 and the second partition 2102 that are independent of each other, so that the air inlet channel 211 and the air outlet channel 212 are spaced apart and independent of each other, thereby forming independent air supply and independent air exhaust to the barrel 10, avoiding mutual interference between the air inlet and outlet inside the barrel 10, and ensuring smooth flow and circulation between the airflow inside the barrel 10 and the external airflow.

[0151] In some embodiments, refer to Figure 8 , Figures 10-11 The guide plate 21 includes a base 213 and a support 214. The base 213 has a groove 2130 on the side facing away from the barrel 10. A through hole 2103 is formed on the bottom wall 2131 of the groove 2130, which communicates with the inner side of the barrel 10. The support 214 is disposed on the bottom wall 2131 and surrounds the through hole 2103 in the circumferential direction. The support 214 cooperates with the bottom wall 2131 and the side wall (not shown in the figure) of the groove 2130 to define a cavity 210 of the guide 210. The cavity 210 surrounds the through hole 2103 in the circumferential direction.

[0152] Reference Figure 8 , Figures 10-11 The partition 22 includes a first partition 221 and a second partition 222. There are two first partitions 221, spaced apart in the cavity 210 along the circumferential direction of the through hole 2103. One end of each first partition 221 is connected to the support portion 214, and the other end is connected to the sidewall of the groove 2130. The two first partitions 221 define a first cavity 2101. Similarly, there are two second partitions 222, spaced apart in the cavity 210 along the circumferential direction of the through hole 2103. One end of each second partition 222 is connected to the support portion 214, and the other end is connected to the sidewall of the groove 2130. The two second partitions 222 define a second cavity 2102.

[0153] In some embodiments, refer to Figures 7-8 , Figures 10-11The air inlet channel 211 includes a first air inlet 2111 and a first air outlet 2112 that are spaced apart and interconnected. The first air inlet 2111 is connected to the air outlet end of the air supply pipe 32, and the first air outlet 2112 is connected to the inside of the barrel 10. The structural design of the first air outlet 2111 being connected to the air outlet end of the air supply pipe 32 allows the airflow delivered by the first fan 31 to the air supply pipe 32 to enter the air inlet channel 211 through the first air inlet 2111 and enter the inside of the barrel 10 through the first air outlet 2112, ensuring smooth airflow and guaranteeing drying efficiency.

[0154] In some embodiments, refer to Figure 8 , Figures 10-12 The first air inlet 2111 and the first air outlet 2112 are spaced apart on the bottom wall 2131 located inside the first partition 2101.

The first fan 31 is disposed in the first support 33. The air intake end of the first fan 31 faces the first inlet 331 and is connected to the first inlet 331. The exhaust end is connected to the air inlet end of the air supply duct 32 through the first outlet 332.

[0159] In some embodiments, refer to Figure 14The air supply duct 32 extends along the height of the barrel 10. The side of the air supply duct 32 facing the barrel 10 is curved, corresponding to the shape of the outer wall of the barrel 10, so as to shorten the distance between the air supply duct 32 and the barrel 10 without interfering with the rotation of the barrel 10 and improve the space utilization.

[0160] In some embodiments, refer to Figure 14 The shape of the side of the first support 33 facing the barrel 10 is an arc surface.

[0161] In some embodiments, refer to Figure 9 The heating element 40 is located at the bottom of the bin 10. The first fan 31 is configured to deliver the hot airflow generated by the first heating element 40 to the inside of the bin 10 through the air supply pipe 32 and the air inlet channel 211. The structural design of the heating element 40 being located at the bottom of the bin 10 allows the heat generated by the heating element 40 to be transferred to the inside of the bin 10 through the bottom of the bin 10, and can also be transferred to the inside of the bin 10 through the side wall of the bin 10, so as to dry the kitchen waste.

[0162] In some embodiments, refer to Figure 9 The heating element 40 includes a heating plate 41 and a heating wire 42. The heating plate 41 is disposed on the bottom wall of the barrel 10 and has an internal receiving cavity (not shown in the figure). The heating wire 42 is disposed in the receiving cavity. During operation, the heating wire 42 generates a hot airflow in the receiving cavity and heats the bottom of the barrel 10 to transfer heat to the inside of the barrel 10. The suction end of the first fan 31 is connected to the inside of the receiving cavity to transport the hot airflow generated by the heating wire 42 to the inside of the barrel 10 through the air supply pipe 32 and the air inlet channel 211. In one example, refer to Figure 9 The first inlet 331 of the first support 33 is connected to the inner side of the receiving cavity, so that the suction end of the first fan 31 is connected to the inner side of the receiving cavity through the first inlet 331.

[0163] In some other implementations, the heating element 40 can be set on the side wall of the barrel 10 or at other positions outside the barrel 10, ensuring that the heating element 40 heats the barrel 10 and the suction end of the first fan 31 is opposite to the heating element 40, so that the hot airflow generated by the heating element 40 can be transported to the inside of the barrel 10 through the air supply pipe 32 and the air inlet channel 211.

[0164] In some embodiments, refer to Figures 7-8 , Figures 10-11The air outlet duct 212 includes a second air inlet 2121 and a second air outlet 2122 that are spaced apart and interconnected. The second air inlet 2121 is connected to the inner side of the barrel 10, and the second air outlet 2122 is connected to the outer side of the barrel 10. This design, with the second air outlet 2122 connected to the outer side of the barrel 10, ensures that airflow from the inner side of the barrel 10 enters the air outlet duct 212 through the second air inlet 2121 and exits to the outer side of the barrel through the second air outlet 2122, guaranteeing smooth airflow from the inner side of the barrel 10 and ensuring effective drying.

[0165] In some embodiments, refer to Figure 8 , Figures 10-11 The second air inlet 2121 and the second air outlet 2122 are spaced apart on the bottom wall 2131 located inside the second partition 2102.

[0166] In some embodiments, refer to Figure 10 The orthographic projection of the second air inlet 2121 is located inside the barrel 10 to guide the airflow inside the barrel 10 into the air outlet duct 212. The orthographic projection of the second air outlet 2122 is located outside the barrel 10 to guide the airflow in the air outlet duct 212 to the outside of the barrel 10.

[0167] In some embodiments, refer to Figure 8 , Figures 10-11 There are multiple second air inlets 2121, which surround the through hole 2103 along the circumferential direction of the through hole 2103. There are multiple second air outlets 2122, which are arranged in a grid pattern.

[0168] In some embodiments, refer to Figure 8 , Figures 10-11 A reinforcing rib 215 is provided between two adjacent second air inlets 2121.

[0169] In some embodiments, refer to Figure 8 , Figures 10-11 The cover 20 also includes a first guide plate 23, which is disposed in the first cavity 2101 and between the first air inlet 2111 and the first air outlet 2112 to guide the airflow entering the air inlet channel 211 through the first air inlet 2111. The first guide plate 23 guides the airflow entering the air inlet channel 211 through the first air inlet 2111, thereby ensuring that the airflow entering the air inlet channel 211 is evenly distributed into the inner side of the barrel 10 through the first air outlet 2112, thus ensuring drying uniformity and drying effect.

[0170] In some embodiments, refer to Figure 8 , Figures 10-11The first guide plate 23 protrudes from the bottom wall 2131 and extends along the circumferential direction of the through hole 2103. One end is connected to a first partition 221, and the other end is located in the first cavity 2101.

[0171] In some embodiments, refer to Figure 8 , Figures 10-11 The cover 20 also includes a second guide plate 24, which is disposed in the second cavity 2102 and between the second air inlet 2121 and the second air outlet 2122 to guide the airflow entering the air outlet channel 212 through the second air inlet 2121. The second guide plate 24 guides the airflow entering the air outlet channel 212 through the second air inlet 2121, thereby directing the airflow into the air outlet channel 212 towards the second air outlet 2122, ensuring the smooth flow of airflow from the inside of the barrel 10 to the outside of the barrel 10 through the second air outlet 2122.

[0172] In some embodiments, refer to Figures 2-4 , Figures 6-7 The cover 20 also includes a cover plate 25, which covers the end of the guide member 21 away from the barrel 10 to form a cover for the cavity 210. The guide member 21 has a through hole 2103 communicating with the inside of the barrel 10. The first cavity 2101 and the second cavity 2102 surround the through hole 2103 along the circumferential direction of the guide member 21. The cover plate 25 is provided with a viewing window 251 opposite to the through hole 2103.

[0173] The structure of the cover plate 25 covering the end of the guide member 21 opposite to the barrel body 10 can seal the inner cavity 210 of the guide member 21, so that the airflow entering the first partition 2101 through the air inlet channel 211 is blocked by the cover plate 25 and enters the inner side of the barrel body 10 through the through hole 2103, preventing leakage and ensuring drying efficiency. It can also allow the airflow entering the air outlet channel 212 through the second air inlet 2121 to be blocked by the cover plate 25 and discharged from the barrel body 10 through the second air outlet 2122, preventing the airflow from being discharged from the top of the barrel body 10.

[0174] The viewing window 251 on the cover 25 allows users to easily observe the processing status of kitchen waste inside the bin 10.

[0175] In some embodiments, the cover plate 25 covers the groove 2130 of the base 213 to close the groove 2130, and the support portion 214 abuts against the cover plate 25 to form a cover for the cavity 210.

[0176] In some embodiments, the guide member 21 has a through hole 2103 communicating with the inner side of the barrel 10. The through hole 2103 forms an air inlet channel 211, the air outlet end of the air supply pipe 32 communicates with the through hole 2103, and the air outlet channel 212 is located outside the through hole 2103. That is, the air inlet channel 211 is not set in the first partition 2101 of the cavity 210, but uses the through hole 2103 as the air inlet channel 211, and the air outlet end of the air supply pipe 32 is directly connected to the through hole 2103 to transport the hot airflow to the inner side of the barrel 10 through the through hole 2103. The air outlet channel 212 is still set in the second partition 2102 of the cavity 210 so that the airflow inside the barrel 10 is discharged from the barrel 10 through the air outlet channel 212.

[0177] In some embodiments, when the through hole 2103 forms an air inlet channel 211, the air outlet end of the air supply pipe 32 extends through the cover plate 25 into the through hole 2103 to transport hot air through the through hole 2103 to the inside of the barrel 10.

[0184] In some embodiments, one end of the guide member 21 is rotatably connected to the mounting base 71, and the guide member 21 is configured to be flip-up relative to the mounting base 71 so that the cover 20 can be opened and placed on top of the barrel 10. In one example, the guide member 21 is rotatably connected to the mounting base 71 by a torsion spring. In another example, the guide member 21 is rotatably connected to the mounting base 71 by a shaft (not shown).

[0185] In some embodiments, refer to Figures 3-5 as well as Figure 16 A base 72 is provided on the inner bottom of the housing 70, as shown in the reference.

The slot 723 is located on the side of the first insertion hole 721 along the length of the base 72 away from the second insertion hole 722. A vent hole 724 is provided on the side wall of the slot 723 adjacent to the first insertion hole 721. The first insertion hole 721 communicates with the inside of the slot 723 through the vent hole 724. A second fan 51 is embedded in the first insertion hole 721, with its exhaust end facing the vent hole 724. One end of the housing 61 in the filter assembly 60, which has an air inlet, is inserted into the slot 723, and the air inlet communicates with the inside of the slot 723. The airflow drawn by the second fan 51 from the inside of the barrel 10 through the exhaust pipe 52 enters the inside of the housing 61 through the vent hole 724, the slot 723, and the air inlet. After being filtered by the filter element 62, the airflow exits the housing 61 through the outlet 611. The base 72 ensures the stability of the second fan 51 and the filter assembly 60 within the housing 70.

[0186] In some embodiments, refer to Figure 5 The motor 85 is inserted into the second socket 722.
