The utility model also arranges a heat insulating cover 5 on the outside of the hot air device 18, and the heat insulating cover 5 is provided with an air outlet 51 connected to the outside, and the circulating air port d is arranged inside the heat insulating cover. Under the suction action of the pneumatic device 19, the high-humidity air generated in the garbage basket 2 enters the second area B through the inlet b, is discharged to the third area C through the ventilation port c, and is finally discharged after being filtered by the filter device 13; part of the high-temperature air generated in the upper space of the garbage basket 2 enters the heat-insulating outer cover 5 through the circulating air port d, and enters the hot air device, is heated again after being mixed with the external cold air, and is discharged from the outlet a to the garbage basket 2.

The utility model adds a heat-insulating outer cover to the outside of the hot air device, and provides a circulating air outlet on the bottom plate inside the heat-insulating outer cover, so that a part of the high-heat and high-humidity air in the garbage basket enters the heat-insulating outer cover for reuse, thereby improving the heating efficiency of the hot air device, thereby improving the dehydration rate, and at the same time, adding a heat-insulating outer cover can reduce the temperature of the internal space of the first area and improve the life of the product.

[0048] When the hot air device 18 is working, the cold air outside the main body 1 is sucked in, and after being heated by the hot air device 18, it forms hot air, which flows into the inner basket 21 of the garbage basket 2 through the outlet a, heats and bakes the kitchen waste 4 in the inner basket 21, and the moisture contained in the waste evaporates to form high-humidity hot air; when the pneumatic device 19 is working, the high-humidity hot air enters the inlet b through the ventilation channel 23 from the ventilation grid 211 at the bottom of the inner basket 21, and then enters the second area B, enters the third area C through the ventilation port c after passing through the pneumatic device 19, and then passes through the odor filter device 13 and is discharged outside the main body 1. The air is sucked in from the outside of the main body 1, heated, the waste is baked, filtered, and then discharged from the main body 1, forming a complete air external circulation process, which accelerates the discharge speed of the water vapor evaporated from the waste, effectively improves the dehydration rate of the waste, reduces the baking time, saves energy and electricity, and improves the consumer's experience.

[0049] As a further preferred embodiment of the present invention, Figure 3 As shown, a transverse partition II15 is also provided in the shell 11, and the transverse partition II15 is buckled on the top of the vertical partition 120 to close the first area A, the second area B and the third area C.

The handle cover 16 is fixedly connected to the transverse partition II15, and the top ring 17 is provided with an air inlet 171, which is connected to the through hole 151 on the transverse partition II15.

[0050] The hot air device 18 used in the present invention includes a heating element 181 and a fan 183. The fan 183 is fixed in the first area A by a bracket 182. The heating element 181 is installed between the outlet of the fan 183 and the guide outlet a. The present invention preferably fixes the hot air device 18 on the inner side of the guide outlet a of the first area A in the outer shell 11 to ensure that the air generated by the fan 183 when working can pass through the heating element 181 to be heated into hot air and then sent out from the guide outlet a. After the heating element 181 is controlled to generate heat, under the action of the fan 183, external cold air enters through the air inlet 171 on the top ring 17, and then enters the fan 183 through the through hole 151. When passing through the heating element 181, a hot air flow is formed, and is injected into the inner basket 21 through the outlet a. The heated air temperature of the heating element and the rotation speed of the fan 183 can be adjusted. Of course, an air filter can be set on the fan pipe to filter the outside air, or the generated high-humidity hot air can be coarsely filtered first, and then discharged after deodorization filtration. The details will not be repeated here.

[0051] like Figure 2 and Figure 4 As shown, as a further preferred embodiment of the present invention, it is more convenient to replace the filter device. The present invention further provides an independent box bin 14 in the third area C. An air guide cavity C1 is formed between the lower end of the box bin 14 and the bottom plate 110, and the vent c is connected to the air guide cavity C1. A window 111 is formed on the side wall of the housing 11 corresponding to the box bin 14. Preferably, a side cover 12 is further provided at the window 111. An exhaust hole 121 is formed on the side cover 12. The exhaust hole 121 is connected to the air outlet grille 132 of the filter device 13. At the same time, a ventilation grille 141 is formed at the bottom of the box bin 14. The ventilation grille 141 is connected to the air guide cavity C1. The filter device 13 is placed in the box bin 14 from the window 111. The replacement of the filter device can be completed quickly without disassembling the entire body 1.

[0052] When in use, kitchen waste 4 is loaded into the inner basket 21, and the main body 1 is placed above the waste basket 2. The fan 183 drives the air outside the main body 1 to be sucked in from the air inlet 171, passes through the through hole 151 on the transverse partition II15 and blows to the heating element 181, and is heated by the heating element 181 to form hot air, and then sent to the inner basket 21 from the outlet a to bake the kitchen waste 4 with hot air, and the moisture contained in the kitchen waste 4 is evaporated by the hot air to form high-humidity air; the pneumatic device 19 works, driving the high-humidity air from the ventilation grid 211 at the bottom of the inner basket 21 into the ventilation channel 23, and then sucked in from the inlet b. Under the action of the pneumatic device 19, the high-humidity air flows from the ventilation port c into the air guide cavity C1 at the lower part of the third area C, passes through the filter device 13 through the ventilation grid 141, and the filter device 13 purifies the odor in the high-humidity air and then discharges it from the exhaust hole 121 of the side cover 12 to the outside of the main body 1. At the same time, the high-temperature air in the space above the garbage basket 21 will partially reflux and re-enter the heat-insulating outer cover from the circulating air outlet d and then the hot air device. This part of the high-temperature air can heat the incoming supplementary air, thereby improving the heating efficiency and helping to protect the hot air device. At the same time, it improves the effect of drying the kitchen waste in the garbage basket and shortens the drying time.

[0053] Through the above continuous air circulation work, the kitchen waste 4 is quickly dried and dehydrated.

[0054] Anything not described in the present invention is applicable to the prior art.

[0055] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present utility model.
