Background

In order to reduce the volume of kitchen waste, prevent excessive propagation of microorganisms and reduce malodor, in the existing kitchen waste treatment mode, dehydration treatment is generally required to be carried out on pure fluid food waste and kitchen waste with high water content, and a common heating mode mainly comprises heating a container or conveying hot air into the container, and drying the kitchen waste through the hot air. Because the direct heating of the container is easy to cause the kitchen waste to be burnt and stuck on the inner wall of the container, the container is difficult to clean and is easy to heat unevenly, and therefore, the hot air drying mode is generally superior to the direct heating mode.

The common hot air heating mode mainly comprises the steps of arranging a hot air mechanism at the top of a container, continuously blowing hot air to the surface of kitchen waste through the hot air mechanism, further achieving the effects of heating and drying the kitchen waste, arranging an air exhausting mechanism and/or a filtering device connected with the container, and discharging redundant air in the container, wherein for example, the multifunctional household waste processor disclosed by the utility model patent with the authorized bulletin number of CN212504636U is characterized in that the hot air is blown to the surface of the kitchen waste from the top, at the moment, the heating speed of the kitchen waste right below the hot air is higher, the heating effect of a part far below the hot air is relatively poorer, so that the heating effect of the surface of the kitchen waste is uneven, meanwhile, the hot air at the top hardly penetrates into the kitchen waste through the surface of the kitchen waste, so that the surface of the kitchen waste is easy to overheat, the inside and the bottom of the kitchen waste cannot contact the hot air, and the longitudinal heating effect is poorer. In addition, a part of kitchen waste treatment devices are also provided with complex exhaust pipelines, such as a heat radiation type air internal circulation kitchen waste dryer disclosed in the patent with the publication number of CN221840010U, on one hand, the internal structure of the machine is complex, the space occupation is overlarge, on the other hand, the exhaust power is insufficient due to the longer pipeline design, and an exhaust device is additionally added to extract the air in the container into a filter for discharging.

In some prior art, the steam outlet is arranged at the side or bottom of the container, such as the upper turnover cover type kitchen waste drying weight-reducing machine disclosed in the patent of the invention with the publication number of CN118758003A, in the dryer, the steam outlet of the water receiving box is arranged on the side wall of the lower part of the water receiving box, and the steam at the steam outlet is sucked into the deodorizing component through the air suction component.

In addition, like a common hot air heating mode, hot air firstly contacts the top of kitchen waste and the bottom of the kitchen waste is more in moisture, or when a container is provided with a water filtering structure, filtered liquid is usually positioned at the bottom of the container, and when hot air at the top of the kitchen waste is recovered from the middle, the filtered liquid cannot contact the liquid at the bottom, and when the hot air is recovered from the bottom, the filtered liquid cannot better evaporate moisture although the hot air can contact the liquid at the bottom, most of heat is lost in the contact process of the hot air and the kitchen waste.
