Description

Technical Field

[0001] The utility model relates to solid waste treatment, in particular to a hot air type garbage treatment machine. Background Art

[0002] When processing kitchen waste, the kitchen waste can be poured into the barrel of a garbage disposal machine. The garbage disposal machine is equipped with a heating source at the bottom of the barrel. When the kitchen waste in the barrel is stirred and shredded, the heating source also heats the barrel, thereby heating the kitchen waste in the barrel to reduce its moisture content. However, during the garbage disposal process, as the heating source heats the interior of the barrel, the garbage at the bottom of the barrel is easily burned, which reduces the heating efficiency of the kitchen waste in the barrel. It is also difficult to clean after use, resulting in a poor user experience. Therefore, there is an urgent need for a garbage disposal machine that can better heat the interior of the barrel to improve the overall user experience. Utility Model Content

[0003] The purpose of the utility model is to provide a hot air type garbage disposal machine to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve its technical problems is:

[0005] A hot air garbage disposer includes: a body with a cavity provided inside; a bottom cover connected to the body and located at the top of the cavity, an air inlet provided on the bottom side of the bottom cover, and an air outlet provided on the side wall of the bottom cover; a first fan connected to the bottom cover, the first fan being used to blow air into the air inlet; and a heating source connected to the first fan, the heating source being used to heat the air outlet of the first fan.

[0006] This technical solution has at least the following beneficial effects: a cavity is provided in the fuselage for pouring kitchen waste into for processing; when the kitchen waste in the cavity needs to be heated, the heating source is started, and the first fan blows air from the air inlet through the bottom cover into the cavity; at this time, the heating source heats the outlet air of the first fan and uses the hot air to heat the inside of the cavity; the heated airflow cooperates with the stirring and shearing of the kitchen waste inside the fuselage to make the kitchen waste come into contact with the heat more fully, thereby accelerating the efficiency of removing moisture and better dehydrating the kitchen waste; the airflow after heat exchange with the kitchen waste turns back upward and is blown out from the air outlet on the side wall of the bottom cover to take away the moisture of the kitchen waste; the kitchen waste is heated by blowing hot air in this way, so that the heating of the kitchen waste inside the cavity is more uniform, effectively reducing the situation where the kitchen waste at the bottom sticks to the bottom due to heating, and improving the drying and dehydration efficiency of the kitchen waste.

[0007] As a further improvement to the above technical solution, an air guide is formed on the bottom side of the bottom cover at the air inlet, and a guide plate is provided at the bottom end of the air guide, the guide plate being tilted toward the lower left, and multiple guide plates are spaced apart in the left-right direction, with air guide gaps formed between two adjacent guide plates. The airflow blown out from the air inlet first passes through the air guide, and after being guided by the guide plate, it is blown into the cavity through the multiple air guide gaps. In this way, by changing the direction of the airflow blowing into the cavity, the airflow is better able to flow around the inner wall of the cavity, thereby improving the flow path of the airflow and increasing the heat exchange efficiency. In actual use, the direction of the stirring and rotating of the kitchen waste in the machine body is coordinated so that the kitchen waste is stirred against the hot air, which can greatly improve the efficiency of heating and dehydrating the kitchen waste.

[0008] As a further improvement to the above technical solution, the bottom end surface of the air guide extends downwardly from left to right, and a plurality of guide plates are spaced apart on the bottom end surface of the air guide. Due to the tilted bottom end surface of the air guide, the airflow from the air guide forms a height difference, which increases the coverage area of ​​the hot air flow entering the cavity, increasing the area of ​​heat exchange contact with the food waste, and thus further improving heat exchange efficiency.

[0009] As a further improvement to the above technical solution, the right bottoms of the plurality of guide plates are provided with beveled angles. Airflow from one air guide gap flows along the guide plate. When it reaches the beveled angle, the flow guided by the beveled angle interferes with the airflow from the adjacent air guide gap, thereby creating turbulence in the airflow from the air guide tube. This further increases the distance traveled by the airflow within the cavity, thereby ensuring a more uniform flow of hot air within the cavity.

[0010] As a further improvement to the above technical solution, the bottom cover has an upwardly protruding air guide groove formed near the air outlet. The air outlet is formed on one side of the air guide groove, and the side of the air guide groove away from the air outlet is curved. When the airflow turns upward and flows outward to the air outlet, the airflow enters the air guide groove, which can be used to converge the airflow and redirect it along the curved side walls of the air guide groove before it is sent to the air outlet. This improves the smoothness of the airflow during delivery and reduces the pressure on the fuselage at the air outlet.

[0011] As a further improvement to the above technical solution, a temperature sensor is provided in the air guide groove, which can monitor the air outlet temperature and help prevent the cavity from being heated to an excessively high temperature.

[0012] As a further improvement to the above technical solution, the present invention further includes a top cover connected to the bottom cover. The top cover has an air inlet directly opposite the air inlet end of the first fan. When the top and bottom covers are connected, they shield and protect the first fan and other electrical components located on the bottom cover, thereby improving the overall appearance. When the first fan is operating, air enters through the air inlet.

[0013] As a further improvement to the above technical solution, the present invention further includes a second fan. The bottom cover is disposed within the fuselage. An exhaust port is disposed on the outside of the fuselage. An exhaust pipe is connected between the exhaust port and the exhaust port. The second fan is configured to deliver air from the exhaust port to the exhaust port. The second fan can draw air from the exhaust port, thereby enhancing the fluidity of the airflow within the cavity and making the temperature distribution within the cavity more uniform. In this case, the bottom cover is located within the fuselage, and the fuselage body can be used to house and protect the second fan, reducing exposure and improving the overall appearance. The airflow after heat exchange is guided through the exhaust pipe to the exhaust port for discharge.

[0014] As a further improvement to the above technical solution, the exhaust pipe is sequentially equipped with an ultraviolet lamp, a photocatalytic plate, and an activated carbon filter, located near the air outlet. After entering the exhaust pipe, the heat-exchanged airflow passes through the ultraviolet lamp, photocatalytic plate, and activated carbon filter before being blown outward. This reduces exhaust odor and disinfects and purifies the exhaust, improving the user experience.

[0015] As a further improvement to the above technical solution, a partition is provided at the air inlet end of the second fan, and the partition is provided with a vent. When the air flows out of the air outlet, it passes through the vent in the partition and enters the exhaust pipe. The partition can block the blown food waste, which helps to reduce the amount of food waste entering the exhaust pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Reference Figures 1 to 3The hot air garbage disposal machine includes a body 100, a bottom cover 200, a first fan 300, and a heating source 400. A cavity 110 is provided inside the body 100. The body 100 includes an outer shell, an inner barrel connected to the outer shell, a stirring paddle for stirring and shearing kitchen waste in the inner barrel, and a driving motor for driving the stirring paddle to rotate. At this time, the cavity 110 is formed inside the inner barrel; the bottom cover 200 is connected to the body 100 and is located at the top of the cavity 110. An air inlet is provided on the bottom side of the cover 200, and an air outlet 210 is provided on the side wall of the bottom cover 200; a first fan 300 is connected to the bottom cover 200, and the first fan 300 is used to blow air into the air inlet; a heating source 400 is connected to the first fan 300, and the heating source 400 is used to heat the air outlet of the first fan 300. In actual applications, the heating source 400 can use electrical components that can heat the air, such as PTC heating sheets or heating wires.

[0027] As can be seen from the above, the body 100 has a cavity 110 for pouring kitchen waste for processing. When the kitchen waste in the cavity 110 needs to be heated, the heating source 400 is started, and the first fan 300 blows air from the air inlet through the bottom cover 200 into the cavity 110. At this time, the heating source 400 heats the air outlet of the first fan 300 and uses the hot air to heat the inside of the cavity 110. The heated air flow cooperates with the stirring and shearing of the kitchen waste inside the body 100 to make the kitchen waste The garbage is in more complete contact with the heat, thereby accelerating the efficiency of removing moisture and better dehydrating the kitchen waste. The airflow after exchanging heat with the kitchen waste is turned back upward and blown out from the air outlet 210 on the side wall of the bottom cover 200, taking away the moisture of the kitchen waste. In this way, the kitchen waste is heated by blowing in hot air, so that the heating of the kitchen waste inside the cavity 110 is more uniform, effectively reducing the situation where the kitchen waste at the bottom sticks to the bottom due to heating, and improving the drying and dehydration efficiency of the kitchen waste.

[0028] In the above embodiment, the first fan 300 can blow air directly downward through the air inlet. In order to improve the heat exchange efficiency between the hot air flow and the kitchen waste, in this embodiment, an air guide tube 220 is formed on the bottom side of the bottom cover 200 at the air inlet. The bottom end of the air guide tube 220 is provided with a guide plate 230. The guide plate 230 is inclined toward the lower left. There are multiple guide plates 230 spaced apart along the left and right directions, and an air guide gap is formed between two adjacent guide plates 230. At this time, multiple air guide gaps arranged along the left and right directions are formed at the bottom end of the air guide tube 220. The air flow blown out from the air inlet first passes through the air guide tube 220, and then is blown into the cavity 110 through multiple air guide gaps after being guided by the guide plate 230. In this way, by changing the direction of the air flow blown into the cavity 110, the air flow can better flow around the inner wall of the cavity 110, thereby improving the flow range of the air flow and thus increasing the heat exchange efficiency. In actual use, the direction of the stirring and rotating of the kitchen waste in the fuselage 100 is coordinated so that the kitchen waste is stirred against the hot air, which can greatly improve the efficiency of heating and dehydrating the kitchen waste.

[0029] To better facilitate airflow along the interior of the cavity 110, in this embodiment, the bottom end surface of the air guide 220 extends downwardly and tilted from left to right, with a plurality of guide plates 230 spaced apart from the bottom end surface of the air guide 220. The tilted bottom end surface of the air guide 220 creates a height difference in the airflow exiting the air guide 220. This increases the coverage area of ​​the hot airflow entering the cavity 110, increasing the area of ​​heat exchange contact with the food waste, and thus further improving heat exchange efficiency.

[0030] In order to enhance the disturbance of the airflow in the cavity 110 and better enable the airflow to flow along the radial direction of the cavity 110, in this embodiment, as shown in FIG. Figure 4 As shown, the right bottom of each of the guide plates 230 is provided with a chamfered corner 231. The airflow from one air guide gap flows along the guide plate 230. When it reaches the chamfered corner 231, the airflow guided by the chamfered corner 231 interferes with the airflow from the adjacent air guide gap, thereby causing turbulence in the airflow from the air guide tube 220. This further increases the distance traveled by the airflow within the cavity 110, thereby making the hot airflow flow more uniform within the cavity 110.

[0031] In the above embodiment, the air outlet 210 can be directly set at the position of the bottom cover 200 near the side wall of the cavity 110. At this time, the upward-returned airflow blows to the bottom side of the bottom cover 200 and disperses to the surroundings. Part of it flows out from the air outlet 210, and part of it is remixed with the hot air flow entering from the air inlet, and then blown into the cavity 110 for heat exchange. In order to improve the exhaust efficiency of the upward-returned airflow, in this embodiment, the bottom cover 200 is upwardly protruded near the air outlet 210 to form an air guide groove 240. The air outlet 210 is formed on one side of the air guide groove 240, and the side of the air guide groove 240 away from the air outlet 210 is arc-shaped. For example, one side of the air guide groove 240 is designed as a curved surface, or an inner corner of the air guide groove 240 away from the air outlet 210 is designed as a chamfered corner. At this time, one side of the air guide groove 240 is connected to the bottom surface of the groove to form an arc surface. When the airflow turns back upward and flows outward to the air outlet 210, the airflow enters the air guide groove 240. The airflow can be converged by using the air guide groove 240, and the airflow is diverted along the curved side wall of the air guide groove 240 before being sent out to the air outlet 210. This can improve the smoothness of the airflow when it is sent out and reduce the pressure of the fuselage 100 at the air outlet 210.

[0032] In some embodiments, a temperature sensor 250 is disposed within the air guide trough 240. The temperature sensor 250 can monitor the outlet air temperature, thereby preventing excessive heating within the cavity 110. In practical applications, a cylindrical structure for mounting the temperature sensor 250 can be disposed at the bottom of the air guide trough 240 to facilitate installation of the temperature sensor 250.

[0033] The bottom cover 200 and the first fan 300 can be directly exposed to the outside. In this case, foreign objects can easily be sucked into the first fan 300, affecting the stability of the overall operation. Therefore, the present invention also includes a top cover 500, which is connected to the bottom cover 200. The top cover 500 is provided with an air inlet 510 at the position opposite the air inlet end of the first fan 300. When the top cover 500 and the bottom cover 200 are connected to each other, they can shield and protect the first fan 300 and other electrical components located on the bottom cover 200, which helps improve the overall appearance. When the first fan 300 is operating, air enters through the air inlet 510. In actual applications, in order to improve the working stability of the first fan 300, a structure for limiting the first fan 300 can be set on the bottom side of the top cover 500. After the top cover 500 is installed on the bottom cover 200, it can be pressed against the bottom cover 200, and the movement of the first fan 300 can be limited by the limiting structure. Similarly, a limiting structure can also be set on the top side of the bottom cover 200, which can facilitate the installation of the first fan 300 and improve the stability of the first fan 300 during use.

[0034] The top cover 500 and the bottom cover 200 can be detachably connected. For example, a mounting post is provided on the bottom side of the top cover 500, and a mounting sleeve is provided on the top side of the bottom cover 200. When the top cover 500 and the bottom cover 200 are combined with each other, the mounting post can be inserted into the mounting sleeve to achieve quick positioning, and screws can be driven into the bottom side of the bottom cover 200 to connect to the mounting post, so as to further tighten and fix the top cover 500 and the bottom cover 200.

[0035] Because the swirling of kitchen waste significantly affects the flow of hot air, in order to improve air discharge efficiency and make the airflow within the cavity 110 more regular, the air intake and outlet directions within the cavity 110 can be enhanced. Specifically, the present invention further includes a second fan 600. The bottom cover 200 is disposed within the body 100. An exhaust port is disposed on the exterior of the body 100. An exhaust pipe 610 is connected between the exhaust port 210 and the exhaust port. The second fan 600 is configured to deliver air from the exhaust port 210 to the exhaust port. The second fan 600 draws air from the exhaust port, thereby enhancing the fluidity of the airflow within the cavity 110 and making the temperature distribution within the cavity 110 more uniform. At this point, the bottom cover 200 is located within the body 100, and the body 100 can house and protect the second fan 600, reducing exposure and improving the overall appearance. The airflow after heat exchange is directed through the exhaust pipe 610 to the exhaust port for discharge.

[0036] Since kitchen waste releases a strong odor during processing, if it is discharged directly, it will have a significant impact on the surrounding environment. Therefore, a structure for filtering the exhaust gas can be provided. Specifically, an ultraviolet lamp, a photocatalytic plate, and an activated carbon filter are sequentially arranged in the exhaust pipe 610 in a direction close to the air outlet 210. The ultraviolet lamp is mainly used to disinfect the surrounding environment, thereby achieving environmental disinfection within the exhaust pipe 610. After entering the exhaust pipe 610, the airflow after heat exchange passes through the ultraviolet lamp, photocatalytic plate, and activated carbon filter in sequence before being blown outward. This can reduce the odor of the exhaust gas and disinfect and purify the exhaust gas, improving the user experience.

[0037] In some embodiments, a partition with vents is provided at the air inlet end of the second fan 600. When air is blown out of the air outlet 210, it passes through the vents on the partition and enters the exhaust pipe 610. The partition can block the blown food waste, thereby reducing the amount of food waste entering the exhaust pipe 610.

[0038] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
