Description

Technical Field

[0001] This invention relates to the field of food waste composting machines, and more particularly to a food waste composting machine. Background Technology

[0002] The existing workflow of a household food waste composting machine is as follows: the gas evaporated from the heated and crushed food waste is blown through an activated carbon filter box by a fan to remove odors before being discharged, resulting in dry, powdered waste. Typically, the gas evaporated from the heated and crushed food waste contains a large amount of water vapor. Actual testing showed that 500 grams of pork bone waste, after drying, yielded 257.5 grams of solid waste, of which 242.5 grams of water evaporated, calculating that the water content of pork bone waste is approximately 48.5%. Vegetable waste has a water content of approximately 96%, meaning that processing 500 grams of waste would result in the evaporation of 480 grams of water.

[0003] Activated carbon typically adsorbs odors and water up to 10% to 50% of its own weight. Using an average of 30%, 8083 grams of activated carbon would be needed to adsorb and process 500 grams of pork bone waste, removing 242.5 grams of water. To adsorb and process vegetable waste, removing 480 grams of water, 16000 grams of activated carbon would be required.

[0004] Currently available food waste composting machines use approximately 500-1000 grams of activated carbon. This is clearly insufficient to handle the 242.5 grams of moisture evaporated from 500 grams of pork bone waste. Once the activated carbon is saturated with moisture, its ability to absorb odors weakens, and the evaporated odors and damp water vapor will dissipate into the air. If the user's environment is poorly ventilated, this can potentially lead to bacterial growth.

[0005] The existing food waste composting machine's air blower is placed in front of the activated carbon filter box. The blower blades are prone to dirt accumulation when in contact with unfiltered steam, and the blower is also inconvenient to disassemble and clean. Summary of the Invention

(1) By setting up a food waste composting machine body and a waste gas treatment mechanism, the waste gas treatment mechanism includes a condensing device and a filter box and a suction device. The condensing device includes a mounting bracket. The mounting bracket is provided with a condensing cavity. The condensing cavity is provided with a condensing channel, a transition channel and an output channel arranged in parallel along the left and right directions. The top of the condensing channel is connected to the steam inlet, the bottom of the condensing channel is connected to the bottom of the transition channel, the top of the transition channel is connected to the top of the output channel, and the bottom of the output channel is connected to the exhaust port. Thus, a steam flow path consisting of a steam inlet, a condensing channel, a transition channel, an output channel and an exhaust port connected in sequence can be formed inside the condensing cavity.

The condensate formed in the condensing channel can be discharged outward through the drain outlet. The interior of the transition channel is equipped with heat sinks. The exhaust port is connected to the air inlet of the filter box. The air suction device is set at the air outlet of the filter box. Thus, in actual use, the gas evaporated by the food waste composting machine body heating and crushing food waste enters the condensing channel through the steam inlet and flows from top to bottom. The heat sink at the top of the condensing channel The steam undergoes a first cooling process. A second cooling process occurs when the heat sink at the bottom of the condensation channel works in conjunction with the refrigeration unit. Condensation on the heat sink surface flows downwards through the drain. The cooled and dried steam enters the transition channel and passes through the heat sink again. This process heats the steam and prevents condensation in subsequent channels. The dried steam then sequentially passes through the output channel, exhaust port, and the inlet of the filter box before entering the filter box. Inside the filter box, the steam undergoes filtration (e.g., by adding activated carbon to filter odors). The filtered steam is then drawn out from the filter box's outlet by the suction device. As the above analysis shows, this invention, compared to existing technologies, adds a condensation device at the filter box's inlet. This condenses moisture in the steam, reducing its moisture content. This improves the filter material's (e.g., activated carbon) ability to absorb odors when saturated with water, thus extending the filter material's lifespan. The suction device, positioned at the filter box's outlet (e.g., a suction fan), comes into contact with the filtered steam and is free of dirt. Attached Figure Description

[0021] See Figures 1 to 15 This embodiment provides a food waste composting machine, including a food waste composting machine body 1 and an exhaust gas treatment mechanism 2. The exhaust gas treatment mechanism 2 includes a condensation device 3, a filter box 4, and an air intake device 5. The condensation device 3 includes a mounting bracket 301, and the mounting bracket 301 has a condensation chamber 302 inside. The condensation chamber 302 has a condensation channel 303, a transition channel 304, and an output channel 305 arranged side by side in the left-right direction. The top end of the condensation channel 303 is connected to a steam inlet 306, the bottom end of the condensation channel 303 is connected to the bottom end of the transition channel 304, and the top end of the transition channel 304 is connected to the top end of the output channel 305. The bottom end of the output channel 305 is connected to the exhaust port 307; the food waste composting machine body 1 can heat and crush food waste. The food waste composting machine body 1 is connected to the steam inlet 306. The top and bottom ends of the condensation channel 303 are respectively provided with heat sinks 308. The heat sinks 308 at the bottom end of the condensation channel 303 are in refrigeration cooperation with the refrigeration device 309. The bottom of the condensation channel 303 is provided with a drain port 310. The condensate formed in the condensation channel 303 can be discharged to the outside through the drain port 310. The interior of the transition channel 304 is provided with heat sinks 308. The exhaust port 307 is connected to the air inlet end of the filter box 4. The air suction device 5 is set at the air outlet end of the filter box 4. Function: (1) By setting up a food waste composting machine body and a waste gas treatment mechanism, the waste gas treatment mechanism includes a condensing device and a filter box, and a suction device. The condensing device includes a mounting bracket, and the mounting bracket has a condensing chamber inside. The condensing chamber has a condensing channel, a transition channel, and an output channel arranged side by side in the left and right direction. The top of the condensing channel is connected to the steam inlet, the bottom of the condensing channel is connected to the bottom of the transition channel, the top of the transition channel is connected to the top of the output channel, and the bottom of the output channel is connected to the exhaust port. Thus, a steam flow path can be formed inside the condensing chamber by sequentially connecting the steam inlet, condensing channel, transition channel, output channel, and exhaust port. See Figure 12, the arrow indicates the airflow direction 16. (2) By setting the food waste composting machine body, it can heat and crush food waste. The food waste composting machine body is connected to the steam inlet. The top and bottom of the condensing channel are respectively equipped with heat sinks. The heat sink at the bottom of the condensing channel is in refrigeration cooperation with the refrigeration device. The bottom of the condensing channel is equipped with a drain outlet. The condensate formed in the condensing channel can be discharged outward through the drain outlet. The interior of the transition channel is equipped with heat sinks. The exhaust port is connected to the air inlet of the filter box. The air suction device is set at the air outlet of the filter box. Thus, in actual use, the gas evaporated by the food waste composting machine body heating and crushing food waste enters the condensing channel through the steam inlet and flows from top to bottom. The heat sink at the top of the condensing channel The steam undergoes a first cooling process. A second cooling process occurs when the heat sink at the bottom of the condensation channel works in conjunction with the refrigeration unit. Condensation on the heat sink surface flows downwards through the drain. The cooled and dried steam enters the transition channel and passes through the heat sink again. This process heats the steam and prevents condensation in subsequent channels. The dried steam then sequentially passes through the output channel, exhaust port, and the inlet of the filter box before entering the filter box. Inside the filter box, the steam undergoes filtration (e.g., by adding activated carbon to filter odors). The filtered steam is then drawn out from the filter box's outlet by the suction device. As the above analysis shows, this invention, compared to existing technologies, adds a condensation device at the filter box's inlet. This condenses moisture in the steam, reducing its moisture content. This improves the filter material's (e.g., activated carbon) ability to absorb odors when saturated with water, thus extending the filter material's lifespan. The suction device, positioned at the filter box's outlet (e.g., a suction fan), comes into contact with the filtered steam and is free of dirt.

[0022] Specifically, the condensation channel 303 is located in the middle of the condensation chamber 302. A transition channel 304 and an output channel 305 are sequentially arranged on the left side of the condensation channel 303, and the same is true for the right side. The bottom ends of the two output channels 305 are connected to two exhaust ports 307, which are connected to the air inlet of the filter box 4. Function: This creates two gas flow paths distributed left and right within the condensation chamber, improving working efficiency. (See also...) Figure 12 The arrow indicates the direction of airflow (16).

[0023] Specifically, the condensing chamber 302 has an upward-facing U-shaped baffle 311 inside, and two vertical baffles 312 distributed horizontally inside the U-shaped baffle 311. A condensing channel 303 is positioned between the two vertical baffles 312. Two transition channels 304 are respectively positioned between the two vertical baffles 312 and the inner walls of the left and right sides of the U-shaped baffle 311. Two output channels 305 are respectively positioned between the outer walls of the left and right sides of the U-shaped baffle 311 and the inner walls of the left and right sides of the condensing chamber 302. Function: The arrangement of the U-shaped baffle 311 and the two vertical baffles 312 encloses the condensing chamber 302, forming the condensing channel 303, two transition channels 304, and two output channels 305. The ventilation gaps left between the U-shaped baffle 311 and the two vertical baffles 312 facilitate smooth steam flow.

[0024] Specifically, the steam inlet 306 is located at the upper left end of the condensing chamber 302, and the drain outlet 310 is located below the U-shaped baffle 311. A partition 313 is provided between the bottom wall of the U-shaped baffle 311 and the bottom wall of the condensing chamber 302. The partition 313 is hollow, and the interior of the U-shaped baffle 311 is connected to the drain outlet 310 through the partition 313. Two exhaust outlets 307 are located at the lower left and lower right of the U-shaped baffle 311, respectively. Function: The partition 313 can separate the two gas flow paths and facilitate the downward discharge of condensate from the interior of the U-shaped baffle 311 through the interior of the partition 313 to the drain outlet 310. Moreover, the two exhaust outlets 307 can be symmetrically distributed on the left and right sides of the drain outlet 310. Preferably, the steam inlet 306 is a channel that curves downward from left to right.

[0025] Specifically, the condensing cavity 302 is located at the rear of the mounting bracket 301. The front of the mounting bracket 301 is provided with an upper heat dissipation groove 314 and a lower heat dissipation groove 315 arranged sequentially from top to bottom. An upper connecting opening 316 is provided between the top of the condensing channel 303, the top of the transition channel 304 and the upper heat dissipation groove 314. A lower connecting opening 317 is provided between the bottom of the condensing channel 303 and the lower heat dissipation groove 315. Heat sinks 308 are installed in the upper connecting opening 316 and the lower connecting opening 317 respectively. The cooling device 309 is a semiconductor cooling chip and is installed inside the heat sink 308 in the lower connecting opening 317. Function: The upper heat sink 314 and the lower heat sink 315 facilitate the heat dissipation of the heat sink 308 of the condensation channel 303 and the transition channel 304. The heat sink 308 passing through the upper connecting opening 316 lacks a cooling device 309, while the heat sink 308 passing through the lower connecting opening 317 is cooled in conjunction with the cooling device 309. Therefore, there is a significant temperature difference between the two. The cooling surface of the semiconductor cooling chip can quickly cool and transfer the heat to the heat sink 308 at the bottom of the condensation channel 303. The heat dissipation surface of the semiconductor cooling chip can transfer the generated heat to the heat sink 308 of the lower heat sink 315.

[0026] Specifically, a vertically arranged heat dissipation box 8 is provided in front of the condensing device 3. An air outlet 9 is provided inside the heat dissipation box 8. An air passage 11 is provided between the heat dissipation box 8 and the upper heat dissipation slot 314 and the lower heat dissipation slot 315. The air outlet 9 can blow cold air through the air passage 11 to the heat dissipation fins 308 of the upper heat dissipation slot 314 and the lower heat dissipation slot 315. An air suction box 6 is provided above the condensing device 3. An air suction device 5 is located inside the air suction box 6. A vent 10 is provided between the air suction device 5 and the heat dissipation box 8. The air suction device 5 can draw the gas from the filter box 4 into the air suction box 6. The air outlet 9 can draw the gas from the air suction box 6 into the heat dissipation box 8. Function: The air outlet device 9 of the condenser blows cold air through the air vent 11 onto the heat sinks 308 of the upper heat sink 314 and the lower heat sink 315, thereby facilitating rapid heat dissipation of the heat sinks 308 of the upper heat sink 314 and the lower heat sink 315; the air intake device 5 draws the gas inside the filter box 4 into the air intake box 6, and the air outlet device 9 draws the gas from the air intake box 6 into the heat sink box 8 through the vent 10, so that the air outlet device 9 can further utilize the cooled gas to rapidly dissipate heat from the heat sinks 308 of the upper heat sink 314 and the lower heat sink 315.

[0027] Preferably, the suction device 5 is a suction fan, the exhaust device 9 is a cooling fan, the heat sink 308 is a heat dissipation aluminum fin, and the filter box 4 is an activated carbon filter box. The right side wall of the suction box 6 has a vent 601, and the right side walls of the upper heat dissipation groove 314 and lower heat dissipation groove 315 have vents 319. A partition plate 318 is provided between the upper heat dissipation groove 314 and lower heat dissipation groove 315. A top cover plate 14 is detachably installed on the top of the suction box 6, and a front cover plate 15 is detachably installed on the front of the heat dissipation box 8. The drain outlet 310 can be a rectangular opening. Functions: The vent 601 allows air to flow inside and outside the suction box 6, while the vents 319 facilitate the dissipation of hot air from the upper heat dissipation groove 314 and lower heat dissipation groove 315. The top cover plate 14 and front cover plate 15 facilitate the installation and removal of internal components. The specific selection of these components further provides those skilled in the art with more specific and common structural options. Of course, these structures can also be adapted to meet actual needs.

[0028] Specifically, the condensing chamber 302 has a hollow column 320 inside, and a pressable latch release button 321 inside the column 320. The side wall of the column 320 has a latching opening 322. A rear cover plate 13 is detachably installed at the rear of the condensing chamber 302. The rear cover plate 13 has a press port 131, and a latch 132 is located on the edge of the press port 131. The latch 132 is covered by a latch cover 133, and the latch 132 engages with the latching opening 322. The latch release button 321 passes through the press port 131, and when the latch release button 321 is pressed, it pushes the latch 132 out of the latching opening 322. Function: With prolonged use, the food waste processing machine will accumulate dirt inside the condensing unit, and the activated carbon filter box will become saturated. Therefore, the condensing unit needs to be cleaned and the activated carbon replaced. The cleaning and installation of this technical solution is very convenient. Simply remove the condenser unit, press the release button, open the back cover, and rinse the inside of the condenser unit directly with water. This is an optional cleaning method, but other cleaning methods can also be selected.

[0029] Specifically, the filter box 4 is vertically positioned behind the condenser 3. The exhaust gas treatment mechanism 2 also includes a housing 12. The housing 12 has an internal mounting groove 121, and below the mounting groove 121 is a drawer slot 122 with an outward opening. The condenser 3, filter box 4, and suction device 5 are housed inside the mounting groove 121. A water collection box 7 is slidably mounted inside the drawer slot 122, and a drain outlet 310 discharges condensate downwards into the water collection box 7. Function: The housing 12, through the mounting groove 121, integrates the condenser 3, filter box 4, and suction device 5 into a single unit. Condensate on the surface of the heat sink flows into the water collection box 7 through the drain outlet 310, allowing the water in the collection box 7 to be drained when it is full.

[0030] Specifically, the exhaust port 307 is connected to the air inlet at the bottom of the filter box 4 via a gas channel 123. The suction device 5 is located at the air outlet at the top of the filter box 4. The gas channel 123 is located on the top surface of the drawer slot 122 and is concave in shape. The drain port 310 is located inside the concave shape of the gas channel 123. The bottom wall of the gas channel 123 has a water outlet 126, which allows condensate to be discharged downwards into the water collection box 7. Function: The concave shape facilitates the gas channel 123 to transport both exhaust ports together into the interior of the activated carbon filter box. Function: This is another optional cleaning method (which can be called steam self-cleaning or activated carbon activation). Specifically, the mixing tank of the food waste composting machine body 1 is cleaned, clean water is added, and the cleaning mode is started (select steam self-cleaning / steam activated carbon mode, the name can be chosen by yourself). The machine will continuously heat the water vapor, which dissolves the internal dirt through the condenser and flows into the water collection box through the drain 310. The high-temperature steam passes through the activated carbon filter box, dissolving the odors adsorbed by the activated carbon and mixing with the water vapor. The steam then condenses into water and flows into the water collection box through the small hole at the bottom (i.e., water outlet 126), extending the service life of the activated carbon (after self-cleaning, only the water in the water collection box needs to be cleaned). It should be noted that when using this cleaning method, the cooling device 309 of the condenser and the air outlet 9 should not be connected to the power supply (to avoid affecting the cleaning effect), while the suction device can be turned on to realize the steam flow, and then exhaust clean air outward (for example, the suction device exhausts clean air outward through the vent 601 on the right side wall of the suction box body 6). This cleans the condenser and activates the activated carbon at the same time. Preferably, the sum of the widths of the gas channel 123 and the drain outlet 310 is less than the width of the water collection box 7, thereby facilitating a stable flow of water into the interior of the water collection box 7 under the influence of gravity.

[0031] Specifically, a handle 124 is provided on the right side of the housing 12, and several heat dissipation holes 125 are provided on the right side wall of the housing 12; an assembly slot 101 is provided at the right end of the food waste composting machine body 1, and the exhaust gas treatment mechanism 2 can be detachably installed into the assembly slot 101. The steam inlet 306 is located inside the assembly slot 101, the opening of the drawer slot 122 faces to the right, and the handle 124 and the heat dissipation holes 125 are located on the right side of the housing 12. Function: When the exhaust gas treatment mechanism 2 is installed into the assembly slot 101, the water vapor and odor generated by the heating and crushing of food waste by the food waste composting machine body can be filtered and dried by the exhaust gas treatment mechanism 2, making it flexible and convenient to use.

[0032] In summary, this invention can effectively condense and dry water vapor. Actual testing shows a condensation efficiency of 62%~70% (62~72 grams of water can be collected in the water collection box 7 after evaporating 100 grams of water). This solves the technical problem that saturation of the activated carbon filter box affects its odor adsorption effect. Beneficial effects: 1. The dried steam passes through the activated carbon filter, solving the problem of saturation affecting odor adsorption and extending the lifespan of the activated carbon. 2. The suction fan is placed at the outlet of the activated carbon filter box, ensuring that the fan blades come into contact with the filtered steam, preventing dirt buildup and odor generation.

[0033] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
