Description

Kitchen waste treatment machine and kitchen waste treatment method Technical Field

[0001] The present application relates to the technical field of kitchen waste treatment, and in particular to a kitchen waste treatment machine and a kitchen waste treatment method. Background Art

[0002] Kitchen waste refers to the waste generated in residents' daily lives and in activities such as food processing, catering services, and corporate meals, including discarded vegetable leaves, leftovers, leftover rice, fruit peels, eggshells, tea residue, chicken bones, fish bones, etc. Kitchen waste is rich in organic matter and can be discharged and used as fertilizer after a series of treatments such as crushing and decomposition. A kitchen waste disposer in the prior art, such as the Chinese utility model patent with announcement number CN212069021U, discloses a treatment barrel for treating kitchen waste having a barrel cover, and a breathable plate is provided on the barrel cover to allow the water vapor generated in the treatment barrel to be discharged. However, in the process of treating kitchen waste, especially in the aerobic composting process, it is very important to maintain a certain humidity in the treatment barrel. Improper treatment of the water vapor generated in the kitchen waste treatment process is not conducive to the rapid decomposition and conversion of kitchen waste into fertilizer. On the other hand, there is a risk that water vapor will enter the operating circuit board in the kitchen waste disposer and cause circuit failure.

[0003] In view of this, it is necessary to propose a new technical solution to overcome the problems existing in the prior art.

[0072]

Methods for handling kitchen waste

[0073] The present application provides a method for treating kitchen waste, as shown in Figures 1 to 5, which can be applied to a kitchen waste disposer 100. As shown in Figures 6 and 7, the kitchen waste disposer 100 includes a base 1 provided with a treatment container, a cover 2 connected to the base 1 and capable of opening or closing the mouth of the treatment container, and a stirring device provided in the treatment container for stirring the kitchen waste. The treatment container is, for example, an inner barrel having a chamber 30; the stirring device is, for example, a stirring member 4 having multiple blades. The kitchen waste disposer 100 also includes a humidity detection device for detecting the humidity in the treatment container, a temperature detection device for detecting the temperature in the treatment container, a ventilation device for ventilating the treatment container, and a heating device for heating the treatment container.

[0074] Please refer to Figure 1. The kitchen waste treatment method is to place microorganisms and kitchen waste in a treatment container, and the microorganisms decompose the kitchen waste. The treatment method includes the following steps: S1. Determine whether the humidity in the treatment container is greater than a first preset humidity; if so, go to S2, if not, go to S3; S2. Adjust the temperature in the treatment container to a first preset temperature, and stir the kitchen waste in the treatment container at a first frequency; S3. Adjust the temperature in the treatment container to a second preset temperature, and stir the kitchen waste in the treatment container at a second frequency; wherein, the first preset temperature is greater than the second preset temperature.

[0075] The stage of executing step S2 is the stage in which the thermophilic bacteria actively participate in the decomposition of food waste in a high temperature and high humidity environment. During this stage, the thermophilic bacteria mainly complete the decomposition of protein and cellulose in the food waste. The first preset humidity is set to a relative humidity between 70% and 90%, that is, the first preset humidity is 70% RH-90% RH. Specific values ​​include, for example, 70% RH, 75% RH, 80% RH, 85% RH, 90% RH, etc. The first preset temperature is set to 40-70°C. The first preset temperature can be a temperature range, and the temperature in the processing container is controlled within a temperature range by controlling the heating device. The first preset temperature can also be a temperature value, and the temperature in the processing container is maintained near a certain temperature value by controlling the heating device. In a specific embodiment, the first preset temperature is controlled within 50-60°C.

[0076] As shown in Figure 2, during step S2, the processing method further includes the following steps: S21. Determining whether the humidity in the processing container is less than a second preset humidity; if so, proceeding to step S3. The second preset humidity is less than the first preset humidity. Step S2 is performed during a period when thermophilic bacteria actively participate in the decomposition of food waste in a high temperature and high humidity environment. During this period, the food waste is decomposed in large quantities, generating a large amount of water vapor, resulting in a high humidity in the processing container. However, since the temperature in the processing container is at the relatively high first preset temperature during step S2, the humidity will gradually decrease due to the large amount of water vapor dissipated. However, since excessively low humidity affects microbial activity, a certain humidity level must be maintained in the processing container throughout the entire food waste decomposition and fertilizer production process. To prevent the humidity from decreasing excessively due to the temperature in the processing container remaining at the relatively high first preset temperature, the process proceeds to step S3 if the humidity in the processing container is determined to be less than the second preset humidity level. In one embodiment, the second preset humidity is 60% RH-80% RH, with specific values ​​being, for example, 60% RH, 65% RH, 70% RH, 75% RH, 80% RH, etc. In one embodiment, during step S2, a fan is started to continuously exhaust air to accelerate the reduction of humidity and prevent the humidity from being too high for a long time, which would cause the food waste in the processing container to remain in a sticky state.

[0077] During step S3, the temperature in the processing container is lower than during step S2, reducing water vapor evaporation. This is the stage where mesophilic bacteria actively participate in the decomposition of food waste. During step S3, the second preset temperature is set to 20-40°C. The second preset temperature can be a temperature range within which the temperature in the processing container is controlled by controlling the heating device; or it can be a temperature value within which the temperature in the processing container is maintained. In one embodiment, the second preset temperature is controlled within 30-40°C. As shown in Figure 3, during step S3, the processing method further includes the following steps: S31. Activating a fan to ventilate the processing container; S32. Determining whether the humidity in the processing container is less than a third preset humidity; if so, proceeding to step S4; wherein, S4. Deactivating the fan, and the third preset humidity being less than the second preset humidity. As the humidity continues to decrease, in order to slow down the humidity drop, the ventilation is closed, and the water vapor produced by fermentation is trapped in the processing container, entering the moisturizing stage, so that the temperature and humidity are maintained in balance, and the mesophilic bacteria continue to actively decompose and produce metabolites such as humus, entering the composting stage. In one embodiment, the third preset humidity is 40% RH-60% RH, and specific values ​​are, for example, 40% RH, 45% RH, 50% RH, 55% RH, 60% RH, etc. During the continuous fermentation of microorganisms, the humidity will increase again. Therefore, in the process of executing step S4, the processing method also includes the following steps: S41. Determine whether the humidity in the processing container is greater than the fourth preset humidity; if so, go to step S31. The fourth preset humidity is 60% RH-80% RH.

[0078] In step S2 and step S3, the kitchen waste needs to be stirred to facilitate the entry of air and facilitate the decomposition of microorganisms. The first frequency used for stirring in step S2 is greater than the second frequency used for stirring in step S3, and the magnitude of the stirring frequency is positively correlated with the degree of reaction activity of the microorganisms. In one embodiment, the stirring at the first frequency is continuous unidirectional rotation or continuous forward and reverse alternating rotation, and the stirring at the second frequency is intermittent unidirectional rotation or intermittent forward and reverse alternating rotation. Preferably, forward and reverse alternating rotation is adopted to disturb and disperse the kitchen waste and facilitate the entry of air.

[0079] As shown in Figure 4, further, during the execution of any of the above steps, each time new food waste is added to the processing container, the above steps are re-executed. Specifically, the processing method further includes the following step: S5. Determining whether new food waste has been added to the processing container; if so, returning to step S1. Prior to step S1, the processing method further includes: S6. Adjusting the temperature of the processing container to a third preset temperature and stirring for a first preset time. This stage is the temperature rise period, during which microorganisms primarily decompose sugars, starches, and other substances. Each time new food waste is added, since the moisture in the food waste has not yet evaporated to form water vapor, the humidity in the processing container detected at this time is not suitable for controlling the decomposition and fertilizer production stage. A period of heating and stirring is required to increase the humidity in the processing container to a higher value, and then control the process to proceed to step S2 or step S3 based on the humidity detected at this time. In one embodiment, the first preset time is 30-60 minutes, with specific values ​​such as 30 minutes, 35 minutes, 40 minutes, 45 minutes, 50 minutes, 55 minutes, and 60 minutes. The third preset temperature is set to be equivalent to the first preset temperature, or within the temperature range of the first preset temperature. Whether new food waste is put into the processing container can be detected by one or more detection means such as an infrared sensor, a pressure sensor, an image sensor, and lid opening and closing detection, which is not limited in this application.

[0080] Please refer to Figure 5. In the process of treating kitchen waste using the kitchen waste treatment method of the present application, the temperature and humidity environment in the treatment container goes through four stages shown in ① to ④. The curve marked T in the figure is the temperature change curve, and the curve marked H is the humidity change curve. Among them, stage ① is the temperature rising period. After it is determined that there is food waste in the treatment container, the temperature is raised. The humidity in the treatment container increases rapidly due to the evaporation of water in the food waste to form water vapor. When the humidity increases to the first preset humidity value, it enters stage ②; stage ② is the high temperature period. At this time, the temperature and humidity in the treatment container are both high, and the thermophilic bacteria are active to quickly decompose the food waste. As stage ② continues, the humidity in the treatment container gradually decreases. At this time, the temperature is controlled to gradually decrease, and the stage ③ cooling period begins. During the cooling period, the thermophilic bacteria are active to continue to decompose the food waste; as the humidity continues to decrease, the ventilation device is turned off to allow the water vapor produced by fermentation to be trapped in the treatment container, entering the moisturizing stage, and finally reaching a state where the temperature and humidity are balanced, entering stage ④ composting period, during which the thermophilic bacteria continue to actively decompose and produce metabolic products such as humus.

[0081] From the above description, it can be seen that the kitchen waste treatment method provided by the present application controls the temperature of the kitchen waste according to the detected humidity in the kitchen waste treatment container, so that the temperature and humidity are controlled in combination with each other, thereby avoiding excessive drop in humidity in the treatment container affecting the decomposition of microorganisms. At the same time, under different temperature and humidity conditions, different microorganisms in the kitchen waste are in an active state, which can shorten the decomposition time of the kitchen waste and is conducive to the microorganisms decomposing the kitchen waste into fertilizer.

[0082] The present application also provides a kitchen waste treatment system for placing microorganisms and kitchen waste in a treatment container, and having the microorganisms decompose the kitchen waste, wherein the treatment system performs the treatment method described above.

[0083] The present application also provides a food waste disposer 100, comprising a processing container for accommodating food waste and microorganisms, a humidity detection device for detecting the humidity in the processing container, and a heating device for heating the processing container, wherein the heating device is configured to control the heating temperature of the processing container according to the humidity detected by the humidity detection device.

[0084] Furthermore, the food waste disposer 100 includes a stirring device for stirring the food waste in the processing container, and the stirring device is configured to operate at different rotation speeds according to the humidity detected by the humidity detection device.

[0085] Furthermore, the food waste disposer 100 includes a ventilation device for ventilating the processing container, and the ventilation device is configured to control operation or stop according to the humidity detected by the humidity detection device. In one embodiment, the ventilation device is an exhaust fan.

[0086] The food waste disposer 100 provided in this application can perform the above-mentioned food waste treatment method without the need to add additional auxiliary materials. It is simple and convenient to operate and can decompose food waste into fertilizer within a few days. The fertilizer can be taken out and mixed into the soil for planting plants.

[0087]

Filter clogging detection

[0088] Please refer specifically to Figures 29 and 30, and in conjunction with Figures 7 and 8, the food waste disposer 100 provided in this application can crush, heat, and decompose and ferment food waste into fertilizer. Referring to Figures 7 and 8, the food waste disposer 100 includes a base 1 and a lid 2 that is openably and closably mounted on the base 1. The base 1 forms a chamber 30 for accommodating food waste, where the crushing, heating, decomposition, and fermentation processes of the food waste occur. The base 1 is provided with buttons and indicator lights for operating the food waste disposer 100 and indicating its operating status. The buttons can be used, for example, to open and close the lid of the food waste disposer 100, start and stop waste processing, and the indicator lights can be used to display the normal operating status, standby status, and abnormal status of the food waste disposer 100.

[0089] As shown in Figures 29 and 30 , the food waste disposer 100 includes a filter element 113. In this embodiment, the filter element 113 is a filter mesh that is removably mounted on the base 1. The filter element 113 is configured to filter the airflow flowing through the filter element 113 from the chamber 30. Specifically, the filter element 113 allows the airflow within the chamber 30 to pass through while preventing the passage of dust within the chamber 30. When the garbage within the chamber 30 is pulverized into powder and the humidity within the chamber 30 is low, the powder will follow the exhaust airflow into the exhaust duct 80, causing the deodorizing and adsorbent substances within the exhaust duct 80 to be rapidly depleted, shortening its service life. Excessive powder accumulation on the filter element 113 can affect exhaust performance, and therefore the filter element 113 needs to be cleaned or replaced regularly. Therefore, it is necessary to perform blockage detection on the filter element 113 to remind the user to clean or replace the filter element 113 promptly.

[0090] As shown in FIG30 , in one embodiment, the food waste disposer 100 includes a humidity detection device 115 . The humidity detection device 115 is used to detect the humidity of the internal environment of the chamber 30 , so that the food waste disposer 100 can execute the waste processing process based on the humidity level, thereby facilitating the conversion of food waste into fertilizer. In one embodiment, the waste processing process includes, for example, when it is determined that the lid has been opened, a heating device heats the chamber 30 for a predetermined period of time, while a stirring device stirs the chamber 30, causing the temperature of the waste in the chamber 30 to rise rapidly. As the temperature rises, the food waste releases moisture, causing the humidity in the chamber 30 to rise rapidly. When the humidity is detected to have risen above a predetermined value, the normal waste processing process begins. If the humidity has not risen to the predetermined value, it is determined that no new waste has been added, and the waste processing process does not proceed. The humidity detection device 115 is located downstream of the filter element 113 in the airflow path. That is, the chamber 30 is considered upstream, and the area outward from the filter element 113 is considered downstream. In other words, the humidity detection device 115 is disposed on a side of the filter element 113 facing away from the chamber 30. Thus, the humidity detection device 115 detects the humidity of the airflow after filtering through the filter element 113, thereby preventing dust from adhering to the humidity detection device 115 and causing inaccurate humidity detection.

[0091] The humidity detected by the humidity detection device 115 serves as an important basis for controlling the food waste treatment process of the food waste disposer 100. This application also utilizes the humidity detection device 115 to detect whether the filter element 113 is clogged. Specifically, the food waste disposer 100 includes a clog determination unit that is in communication with the humidity detection device 115 and configured to determine whether the filter element 113 is clogged based on changes in humidity detected by the humidity detection device 115. In one embodiment, the clog determination unit is configured to determine that the filter element 113 is clogged when the rate of change of humidity detected by the humidity detection device 115 is less than a preset value. The preset value can be pre-set based on the rate of change of humidity under normal conditions when the filter element 113 of the food waste disposer 100 is unobstructed. In one embodiment, when the humidity value detected by the humidity detection device 115 increases at a slower rate than normal, it is determined that the filter 113 may be clogged. If the humidity value increases slowly two or more times, it is determined that the filter 113 is clogged, and the user is prompted to clean or replace the filter 113. The blockage determination unit can be configured as a controller, a control chip, or a module integrated into the controller; the communication connection can be wired or wireless.

[0092] Referring to Figures 29 and 30, the food waste disposer 100 includes an exhaust passage 80 in communication with the chamber 30, and the filter element 113 is disposed between the chamber 30 and the exhaust passage 80. The exhaust passage 80 is used to discharge the gas in the chamber 30 out of the food waste disposer 100 after deodorization. The humidity detection device 115 is disposed in the exhaust passage 80 and close to the filter element 113. The proximity of the humidity detection device 115 to the filter element 113 can prevent the measured humidity value from being too far away from the filter element 113, which may result in an excessive difference between the actual humidity value of the gas in the chamber 30 and inaccurate humidity detection.

[0093] Furthermore, the food waste disposer 100 also includes a blockage reminder unit, and the blockage reminder unit is configured to issue a reminder message when the blockage judgment unit determines that the filter element 113 is blocked. In one embodiment, the reminder message includes lighting an indicator light; in another embodiment, the reminder message includes emitting a prompt sound; in yet another embodiment, the reminder message may be lighting an indicator light and emitting a prompt sound at the same time. Furthermore, the food waste disposer 100 may also include a blockage processing unit, and the blockage processing unit is configured to automatically clean the filter element 113 when the blockage judgment unit determines that the filter element 113 is blocked. The blockage processing unit may, for example, include a cleaning mechanism in which a motor drives a brush to move, and the brush cleans the filter element 113. If it is still determined to be blocked after several cleanings, a reminder message is issued.

[0094] As can be seen from the above description of the specific embodiment, the food waste disposer 100 provided by the present application includes a humidity detection device 115 and a blockage judgment unit. The humidity detection device 115 is located downstream of the filter element 113 on the flow path of the airflow. The humidity detection device 115 is configured to detect the humidity of the airflow after passing through the filter element 113. The blockage judgment unit judges whether the filter element 113 is blocked based on the humidity change detected by the humidity detection device 115. That is, the present application realizes blockage detection of the filter element 113 without adding any additional detection devices by making the humidity detection device 115, which is necessary for achieving temperature and humidity control, also serve as the blockage judgment unit of the filter element 113.

Base and cover

[0096] Please refer to Figures 6 to 14 , and the structures of the base 1 and the cover 2 included in the food waste disposer 100 of the present application will be described in detail below.

[0097] Please refer to Figures 10 and 11 in particular. The base 1 is provided with a chamber 30 for accommodating kitchen waste. Specifically, the base 1 includes an outer shell 11, an inner barrel 13 fixed in the outer shell 11, and a top seat 12 connected to the outer shell 11 and the inner barrel 13. The chamber 30 is formed inside the inner barrel 13. The top seat 12 is annular, and the lower end surface of the annular top seat 12 abuts against the edge of the top opening of the inner barrel 13, and the upper end surface of the annular top seat 12 is used for abutment when the cover body 2 is closed. When the lower end surface of the annular top seat 12 is placed horizontally, the upper end surface is inclined. That is, the upper end surface of the top seat 12 is configured as a support surface 120 for the cover body 2 to abut when closed, and the support surface 120 is inclined relative to the horizontal plane.

[0098] Continuing to refer to Figures 10 and 11, the lid 2 is openably and closably mounted on the top opening of the chamber 30. The lid 2 has a lower surface 220 facing the interior space of the chamber 30. When the food waste disposer 100 is in normal use, the lower surface 220 is the downwardly facing surface. When the water vapor in the chamber 30 flows upward and hits the lower surface 220 of the lid 2, it flows back inward. When the temperature of the lower surface 220 of the lid 2 is low, the water vapor condenses into water droplets on the lower surface 220. The lower surface 220 is suitable for condensation of condensed water thereon, and the lower surface 220 is inclined from one end to the other end opposite to the horizontal plane. In this embodiment, the lid 2 has a pivot end 202 pivotally connected to the base 1, and the lower surface 220 is inclined from top to bottom from the pivot end 202 to the other end opposite to the pivot end. Such a setting allows the condensed water to flow away from the pivot end 202 under normal use, which can prevent excessive condensed water from gathering at the pivot end 202 at the moment of opening the cover, causing liquid to splash out and affecting the user experience. As shown in Figure 11, the tilt setting is configured to have an inclination angle A of 5°-15° relative to the horizontal plane. Preferably, the inclination angle is set to 6°-10°, and specifically can be set to 6°, 7°, 8°, 9°, etc. The other end of the cover body 2 opposite to the pivot end 202 is a clamping end 201, and the clamping end 201 is connected to the base 1 by an elastic clamp 25. In one embodiment, the elastic clamp 25 includes a button, a slider and a spring. The spring elastically abuts the slider so that the slider is in a position to be clamped with the hook on the base 1. Pressing the button will push the slider to slide, thereby releasing the clamping from the hook on the base 1.

[0099] In this embodiment, the cover body 2 includes a lining cover 21, a cover plate 23 provided on the lining cover 21, and an inner cover 22 fixed on the lining cover 21. The bottom surface of the inner cover 22 forms the lower surface 220 of the cover body 2. The inner cover 22 is a metal part, that is, the inner cover 22 is a metal inner cover. The lining cover 21 is used for installing the cover body 23 and the inner cover 22. The lining cover 21 is also provided with an elastic member for popping the cover body 2 open. The elastic member is used to pop the cover body 2 open to facilitate opening the cover when the clamping end 201 is released from the base 1. In this embodiment, the elastic member is a cover-opening torsion spring 24. The cover body 2 is also provided with a sealing ring 26 for sealingly contacting the support surface 120 of the top seat 12 of the base 1. In this embodiment, the sealing ring 26 is fixed on the lining cover 21 and is arranged around the periphery of the inner cover 22. The sealing ring 26 can form a sealed connection between the cover body 2 and the base body 1 to prevent the gas in the chamber 30 from flowing out through the gap between the cover body 2 and the base body 1, and can play a role in sealing and moisturizing and preventing the leakage of unpleasant odors.

[0100] As shown in Figure 12, the inner cover 22 extends along a plane as a whole, and when placed on the base 1, it is arranged obliquely along the plane as a whole. While the inner cover 22 extends along a plane as a whole, it also forms a concave-convex structure. Specifically, the lower surface 220 of the inner cover 22 is provided with a plurality of protrusions 221 protruding toward the internal space of the chamber 30. The protrusions 221 are suitable for allowing condensed water to gather and drip into the chamber 30 under the action of its own gravity. The lower surface 220 is provided with a concave portion 222 protruding toward the internal space away from the chamber 30 between two adjacent protrusions 221. The concave portion 222 is connected to the protrusion 221 to form a wave shape. In this embodiment, the inner cover 22 is a metal sheet, and the wave shape formed by the concave portion 222 and the protrusion 221 is formed by pressing the metal sheet. In this embodiment, the widths and protrusion heights of the multiple inner recesses 222 and the multiple protrusions 221 gradually decrease from the center of the lower surface 220. As shown in Figure 11, the centerline L is the central axis of the inner cover 22. The inner cover 22 includes several raised and recessed circles radially outward from the centerline L. The raised and recessed circles closer to the centerline L have greater widths and protrusion heights than those further away from the centerline L. This arrangement allows condensed water to accumulate more in the center of the inner cover 22.

[0101] The usage process of the kitchen waste disposer 100 provided in the present application is as follows: kitchen waste and microorganisms are placed in the chamber 30 of the kitchen waste disposer 100, the cover 2 is closed, and the kitchen waste disposer 100 is powered on; the kitchen waste disposer 100 heats, stirs, cuts and crushes the kitchen waste, and the microorganisms decompose the kitchen waste residues and convert them into fertilizer. During this process, the water vapor in the chamber 30 encounters the condensed water formed on the lower surface 220 of the cover 2, and can flow along the inclined lower surface 220 and gather at the raised portion 221 on the lower surface 220, and drip back into the chamber 30; after the treatment is completed or new garbage needs to be added, the clamping end of the cover 2 is pressed to release the clamping, and the cover 2 is bounced open by the cover-opening torsion spring 24.

[0102] From the above description, it can be seen that the kitchen waste disposer 100 provided in the present application has a cover body 2 with a lower surface 220 facing the internal space of the chamber 30, and the lower surface 220 is suitable for condensed water to condense thereon. The lower surface 220 is inclined with respect to the horizontal plane from one end to the other end opposite to the end, so as to facilitate guiding the condensed water to drip into the chamber 30 in time under its own gravity, thereby avoiding excessive condensed water from accumulating on the cover body 2 and splashing when the user opens the cover, affecting the user experience.

[0103] Please continue to refer to Figures 6 to 14. The base 1 has a front end 101 and a rear end 102 relative to each other, and the cover 2 is pivotally connected to the rear end 102 of the base 1. In this embodiment, the cover 2 can be rotated and opened in a vertical plane relative to the base 1. The front end 101 is the end of the base 1 that the cover 2 moves away from when opening. It is also the end where the user usually stands when putting garbage in. It is the end of the food waste disposer 100 that is usually facing the user under normal use. The rear end 102 is the end opposite to the front end 101, the end to which the cover 2 is pivotally connected, the end that the user usually moves away from when putting garbage in. It is the end that the food waste disposer 100 usually faces away from the user under normal use.

[0104] Please refer to FIG9 in particular. The base 1 is provided with an operating portion 3 for operating the kitchen waste disposer 100. The operating portion 3 is located at the rear end 102 of the base 1. The operating portion 3 is located at the rear end 102 of the base 1, so that when garbage is put in, it is not easy for liquids such as oil, soup, etc. to drip onto the operating portion 3, solving the problem of the operating portion 3 being easily contaminated and water entering the operating portion 3 causing circuit failure. The cover 2 has a pivot end 202 pivotally connected to the base 1. When viewed from the front end 101 to the rear end 102 of the base 1, the operating portion 3 is located behind the pivot end 202. As shown in FIG7 and FIG8, when the cover 2 is in the open state, the operating portion 3 is blocked by the cover 2 when viewed from the front end 101 to the rear end 102 of the base 1. In this way, when the user throws the kitchen waste with too much force, the kitchen waste will be blocked by the cover 2 and will not be thrown onto the operating part 3, which can prevent the kitchen waste from being thrown onto the operating part 3 when the cover is open; and because the operating part 3 is blocked in the open state, it is inconvenient for the user standing at the front end 101 of the kitchen waste disposer 100 to touch the operating part 3, which can prevent the user from accidentally touching the operating part 3 in the open state and causing the kitchen waste disposer 100 to start one or more functions such as stirring, crushing, heating, exhausting, deodorizing, and keeping warm, which may cause user injury, kitchen waste being thrown out, malfunction of the kitchen waste disposer 100, and other problems.

[0105] The top of the base 1 is tilted downward from the rear end 102 toward the front end 101. In other words, the top rear end 102 of the base 1 is higher than the front end 101. With this arrangement, when the lid 2 is closed onto the base 1, the operating portion 3 is relatively high and on a slightly inclined surface toward the user, making it convenient for the user to operate the operating portion 3 while standing at the front end 101. In one embodiment, the tilted arrangement is configured to have an angle A relative to the horizontal plane of 5°-15°, for example, 6°, 8°, 10°, 12°, 14°, etc. After the lid 2 is placed onto the base 1, it also tilts downward from the rear end 102 toward the front end 101 of the base 1. This arrangement allows condensed water formed on the inner surface of the lid 2 to flow toward the front end 101 under the action of gravity and drip back into the waste disposal chamber within the base 1, preventing the risk of water intrusion into the operating portion 3 caused by condensed water flowing toward the rear end 102 where the operating portion 3 is located.

[0106] 10 and 13 , the rear end 102 of the base 1 is configured with a high-step surface 121 and a low-step surface 122 having a height difference. The high-step surface 121 and the low-step surface 122 are connected by a connecting surface 123 to form a stepped surface. The operating portion 3 is disposed on the high-step surface 121, and the pivot end 202 is connected to the low-step surface 122. The provision of the stepped surface allows the top surface of the food waste disposer 100 to be substantially flush when the cover 2 is closed on the base 1, thereby reducing obstruction of the operating portion 3 when the cover 2 is in the closed state and also making the top surface of the food waste disposer 100 smooth and aesthetically pleasing. Furthermore, the edge of the pivot end 202 is located directly above the low-step surface 122, so that when the lid 2 is pivoted open, liquid on the lid 2 can drip from the edge of the pivot end 202 onto the low-step surface 122, and then flow from the low-step surface 122 into the garbage disposal chamber. This prevents condensation from flowing onto the operating portion 3 when the lid is opened, potentially causing water ingress. In this embodiment, the base 1 includes a housing 11 and a top seat 12 mounted on the top of the housing 11. The operating portion 3 is disposed on the top seat 12, and the stepped surfaces are all formed on the top seat 12. The top seat 12 is configured with a support surface 120 for the lid 2 to abut when closed. The lid 2 is provided with a sealing ring 26 that seals against the support surface 120. The sealing ring 26 ensures a seal when the lid 2 is closed on the base 1, preventing odor from escaping between the lid 2 and the base 1. The use of a top seat 12 that is separate from the outer shell 11 facilitates the molding of its structure and the installation of related components. Specifically, an operating circuit board 31 is fixed to the bottom of the high-level surface 121, and the operating part 3 is a button suitable for triggering the operating circuit board 31 to send an electrical signal. The operating circuit board 31 is also provided with an indicator light for indicating the working status of the food waste disposer 100. A light-transmitting plate is also installed above the indicator light to transmit and guide light. The operating circuit board 31 and the light-transmitting plate are installed to the bottom of the high-level surface 121 via a mounting bracket 32. Referring to Figures 13 and 14, a button hole 1210 is provided on the high-level surface 121 for the operating part 3 to pass through, and a mounting position 1211 that matches the mounting bracket 32 ​​is provided on the lower surface of the high-level surface 121. A pivot seat 114 is fixedly connected to the low-level surface 122, and the pivot end 202 of the cover body 2 is rotatably connected to the pivot seat 114. The low-level surface 122 is provided with a pivot seat connection portion 1221 that is matched with the pivot seat 114 .

[0107] During use, the user presses the elastic buckle of the locking end 201 of the cover body 2 to release the lock. At this time, the cover body 2 rotates open around the pivot seat 114 under the action of the torsion spring, and the user puts kitchen waste into the garbage disposal chamber of the base 1. At this time, the operating part 3 is blocked by the cover body 2, and the kitchen waste will not contaminate the operating part 3. It is also inconvenient for the user to operate the operating part 3 at this time, which can prevent misoperation in the open state; the user presses down the cover body 2 so that the locking end 201 of the cover body 2 is locked on the base 1. In the closed state, the user can touch the operating part 3 to start the kitchen waste disposer 100 to start working.

[0108]

Fertilizer discharge part

[0109] Please refer to Figures 15 to 21. The kitchen waste disposer 100 provided in the present application is used to process kitchen waste into powder. In one embodiment, the kitchen waste disposer 100 is used to crush kitchen waste and mix it with microorganisms, and provide an environment conducive to the decomposition of kitchen waste by microorganisms, so as to decompose the kitchen waste into fertilizer and discharge it. The kitchen waste disposer 100 includes a base 1, a cover 2, a stirring member 4, a baffle 5, a crushing knife 6 and a receiving box 7. The base 1 includes an inner barrel 13, and the cover 2 is rotatably connected to the base 1 to open and close the barrel mouth of the inner barrel 13. The inner barrel 13 forms a chamber 30 for accommodating kitchen waste, and the stirring member 4 and the crushing knife 6 are arranged in the chamber 30 for crushing and stirring the kitchen waste. The inner barrel 13 is formed with a discharge hole 301 for the processed kitchen waste powder to be discharged from the chamber 30. The baffle 5 is arranged outside the chamber 30 for opening and closing the discharge hole 301. The receiving box 7 is arranged below the discharge hole 301 for receiving the powder discharged from the discharge hole 301.

[0110] Please refer to Figures 15 and 16. The chamber 30 is cylindrical and is surrounded by a bottom wall and an annular circumferential side wall. The bottom wall of the chamber 30 is provided with a plurality of discharge holes 301. In one embodiment, the plurality of discharge holes 301 are configured as mesh holes arranged in a matrix, so that the size of each mesh hole is small, which can prevent garbage residues with excessively large particle sizes from being discharged. In one embodiment, the discharge hole 301 is a trumpet hole with a gradually increasing aperture from top to bottom, so that the powder entering the discharge hole 301 can easily fall out of the discharge hole 301. In one embodiment, the inner wall surface of the discharge hole 301 is also provided with a non-stick layer, which can reduce the adhesion of the powder to the inner wall surface of the discharge hole 301, thereby facilitating the discharge of the powder. Please refer to Figures 19 and 20 together. The stirring member 4 is arranged in the chamber 30 to stir the kitchen waste. The stirring member 4 is driven to rotate by a stirring motor 45. The stirring member 4 includes a stirring shaft 41 and a stirring blade 42 provided on the stirring shaft 41. The stirring shaft 41 is connected to the stirring motor 45 and is driven to rotate by the stirring motor 45. At least one stirring blade 42 can rotate and move to sweep over the discharge hole 301. The powder is discharged from the discharge hole 301 under the extrusion force of the stirring member 4. Please refer to Figure 25 together. The stirring blade 42 is provided with an inclined surface 4231 that can form a wedge-shaped space with the inner surface of the bottom wall of the chamber 30. The inclined surface 4231 is suitable for squeezing the kitchen waste powder entering the wedge-shaped space into the discharge hole 301. The wedge-shaped space has a relatively large opening, with the height gradually decreasing inward from the opening. This allows the powdered material entering the wedge-shaped space to be squeezed into the discharge hole 301 by the inclined surface 4231 as the stirring blade 42 moves across the discharge hole 301. In this embodiment, the inner surface of the bottom wall of the chamber 30 is horizontal, and the inclined surface 4231 forms an acute angle with the horizontal plane of the inner surface of the bottom wall of the chamber 30. There can be one or more stirring blades 42. In this embodiment, there are three stirring blades 42, arranged at different heights on the stirring shaft 41, namely, low, medium, and high. The inclined surface 4231 is formed on the stirring blade 42 at the lowest position, that is, closest to the inner surface of the bottom wall of the chamber 30. In this embodiment, the inclined surfaces 4231 are arranged on both sides of the bottom surface of the stirring blade 42, so that the food waste powdered material can be squeezed into the discharge hole 301 during both forward and reverse rotation of the stirring blade 42. By such a configuration, the size of the discharge hole 301 can be made smaller, which can prevent garbage residues with too large particle size that do not meet the requirements from being discharged. At the same time, by squeezing out the kitchen waste powder, it can avoid poor discharge of the powder.

[0111] Continuing with Figures 15 and 16 , the outer surface of the bottom wall of the chamber 30 is provided with an arcuate concave surface 131 corresponding to the discharge hole 301. This arcuate concave surface 131 is adapted to engage with the stopper 5. A pivot lug 132 is provided on the outer surface of the bottom wall of the chamber 30, adjacent to the discharge hole 301, for pivotally connecting the stopper 5. The stopper 5 is configured to switch between opening and closing the discharge hole 301. One end of the stopper 5 is provided with a pivot shaft 54, which is rotatably connected to the pivot lug 132 on the bottom surface of the chamber 30. A motor 55 is connected to the other end of the stopper 5. The motor 55 drives the stopper 5 to rotate about the central axis of the pivot shaft 54, switching between opening and closing the discharge hole 301.

[0112] Please refer to Figures 17 to 19 . The blocking member 5 is provided with a blocking surface 501 that matches the arcuate concave surface 131. When the blocking surface 501 is aligned with the arcuate concave surface 131, the discharge hole 301 is covered, and powder is not discharged from the discharge hole 301. When the blocking surface 501 is rotated to be offset from the arcuate concave surface 131, the discharge hole 301 is opened, and powder can be discharged from the discharge hole 301. The blocking surface 501 is configured as a curved surface to decompose the pressure exerted on the blocking surface 501 by the powder in the discharge hole 301 into two components: a force along the tangent direction of the curved surface and a force perpendicular to the tangent direction. As shown in FIG19 , the discharge hole 301 extends in the vertical direction and passes through the bottom wall of the chamber 30 from top to bottom. When the stirring member 4 rotates, scrapes, and squeezes the powder into the discharge hole 301, the pressure exerted by the powder in the discharge hole 301 on the blocking surface 501 is a vertical downward pressure F. The pressure F can be decomposed into a force component F2 along the tangential direction of the curved surface and a force component F1 perpendicular to the tangential direction. The force component F1 perpendicular to the tangential direction is also the force component extending along the normal direction of the curved surface. This arrangement allows the multiple force components F2 along the tangential direction of the multiple force points corresponding to each discharge hole 301 on the blocking surface 501 to extend to both sides of the curved surface. The intersection of the multiple force components F1 along the normal direction of the multiple force points can partially offset each other, thereby making the blocking member 5 have a strong load-bearing capacity, less prone to deformation due to stress, and good reliability in controlling the opening and closing of the discharge hole 301. It should be noted that when the baffle 5 is in the position of covering the discharge hole 301, there may be one or several pressures F exerted downward on the baffle 5 by the powder in the discharge holes 301, which just extends along the normal direction of the surface at that point. In this case, there is no component force along the tangential direction; for this application, there is at least one pressure exerted on the sealing surface 501 by the powder in the discharge hole 301, which can be decomposed into two components along the tangential direction of the surface and perpendicular to the tangential direction.

[0113] In this embodiment, the blocking surface 501 is an arched surface. The baffle 5 is also provided with a scraping portion 503, which is configured to scrape the lower end of the discharge hole 301 when the baffle 5 switches from an open state to a closed state. In this way, the powder material still hanging at the lower end of the discharge hole 301 at the end of the discharge process can be scraped off, preventing the powder material from being squeezed between the blocking surface 501 of the baffle 5 and the arc-shaped concave surface 131 on the bottom surface of the chamber 30, causing the motor 55 to stall. In this embodiment, the cross-sectional profile of the baffle 5 is arched, and the baffle 5 includes a plane 502 connected to the blocking surface 501, and the connecting edge of the plane 502 and the blocking surface 501 forms the scraping portion 503. Specifically, the stopper 5 includes an arched plate 51 and side plates 511 disposed at both ends of the arched plate 51 in the axial direction. The arched plate 51 and the side plates 511 form a hollow portion. Disposed within the hollow portion are a plurality of arched support plates 53 supporting the arched plate 51. The support plates 53 are arranged axially along the arched plate 51. The support plates 53 enhance the structural strength of the arched plate 51. The stopper 5 also includes a bottom plate 52 covering the bottom end of the hollow portion. The surface of the bottom plate 52 forms the plane 502. In this embodiment, the hollow design of the stopper 5 reduces its weight and reduces the load on the motor 55.

[0114] The baffle 5 is driven by the motor 55 to rotate so as to switch between the states of opening and closing the discharge hole 301. The opening and closing of the discharge hole 301 is achieved by rotation. Compared with the translational plug-in type plug-in plate, the movement space occupied is smaller, which is more conducive to the overall structural design of the food waste disposer 100. The motor 55 drives the baffle 5 to rotate through a gear set. Specifically, the motor 55 is fixed to the bottom wall of the inner barrel 13 through a bracket 552, and the output shaft of the motor 55 is connected to the driving gear 551, and the baffle 5 is provided with a driven gear 56. The output shaft of the motor 55 drives the driving gear 551 to rotate, and the driving gear 551 engages with the driven gear 56 to drive the driven gear 56 to drive the baffle 5 to rotate. In this embodiment, the driven gear 56 is integrally formed on the baffle 5; in other embodiments, the driven gear 56 can also be an independent component assembled on the baffle 5.

[0115] Figures 15, 16, and 19 illustrate one embodiment of the baffle 5, while Figures 17, 18, 20, and 21 illustrate another embodiment of the baffle 5. In the embodiments shown in Figures 17, 18, 20, and 21, the baffle 5 is a solid cylinder. Specifically, the baffle 5 has a fan-shaped cross-section and includes two flat surfaces 502 connected to a blocking surface 501. The connecting edges of the two flat surfaces 502 and the blocking surface 501 form the scraping portion 503. The intersection of the flat surfaces 502 and the blocking surface 501 forms a sharp angle, which facilitates scraping away powder hanging from the lower end of the discharge hole 301.

[0116] Please refer to Figures 20 and 21 for details. The material receiving box 7 is placed below the material discharge hole 301 in a removable manner. In this embodiment, the material receiving box 7 is taken out by horizontal pulling. As shown in Figure 20, when the blocking member 5 is in the state of covering the material discharge hole 301, it does not hinder the pulling and pushing of the material receiving box 7. At this time, the material receiving box 7 can be pulled out or pushed in freely. As shown in Figure 21, when the blocking member 5 is in the state of opening the material discharge hole 301, it is combined with the material receiving box 7. At this time, the blocking member 5 partially protrudes into the material receiving box 7, thereby preventing the material receiving box 7 from being taken out. This arrangement can avoid the problem of powder falling into the base 1 or the external environment due to the removal of the material receiving box 7 during material discharge.

[0117] In this embodiment, the food waste disposer 100 is suitable for mixing microorganisms into the food waste for aerobic composting, and the stirring element 4 is also suitable for stirring the food waste during the aerobic composting process to increase the inflow of air. Increasing the inflow of air into the food waste by stirring is conducive to the microorganisms decomposing the food waste and converting it into fertilizer.

[0118]

Mixing and crushing part

[0119] Please refer to Figures 22 to 27 for a detailed description of the garbage crushing device of the food waste disposer 100. The garbage crushing device is used to crush garbage, especially for crushing food waste. In one embodiment, the food waste disposer is used to crush food waste and mix it with microorganisms, and provide an environment conducive to the decomposition of food waste by microorganisms, so as to decompose the food waste into fertilizer for discharge. The food waste disposer includes a base 1, a cover 2, an inner barrel 13, a movable cutting member, a fixed cutting member and a power source. In one embodiment, the movable cutting member is, for example, a stirring member 4, the fixed cutting member is, for example, a crushing knife 6, and the power source is, for example, a stirring motor 45. The inner barrel 13 is arranged in the base 1, and the cover 2 is rotatably connected to the base 1 to open and close the barrel mouth of the inner barrel 13. The inner barrel 13 forms a chamber 30 for accommodating food waste. The movable and fixed cutting members are disposed within the chamber 30. The movable cutting member is driven to rotate by the power source to cooperate with the fixed cutting member to crush and agitate the food waste. The inner barrel 13 also includes a discharge port 301 for discharging the processed food waste powder from the chamber 30.

[0120] The movable cutting member is an integrally cast metal member, which includes a central axis portion (such as a stirring shaft 41) and a plurality of blades (such as stirring blades 42) extending radially from the central axis portion. The central axis portion is used to be sleeved on the output shaft of the power source. In this embodiment, the power source is a motor. At least one blade of the movable cutting member is provided with a sorting portion 4211, and the sorting portion 4211 is configured to be suitable for sorting the garbage in the chamber 30 by turning up and / or pressing down during the movement of the blade. At least one blade of the movable cutting member is arranged below the sorting portion 4211 and is configured to cooperate with the fixed cutting member during the movement to cut off the garbage sorted by the sorting portion 4211. This arrangement allows the garbage to be sorted by turning up and / or pressing down by the sorting portion 4211 during the process of the movable cutting member crushing the garbage, so as to change the posture of the garbage and put the garbage in a posture that is conducive to cutting, thereby improving the crushing effect.

[0121] Please refer to Figures 22 to 24. Specifically, the sorting portion 4211 is an inclined plate portion extending obliquely from a vertical plane. The inclined plate portion is suitable for flipping up garbage when the movable cutting member rotates in a first direction and pressing down garbage when the movable cutting member rotates in the opposite direction to the first direction. The sorting portion 4211 has a relative upward flipping surface S1 and a downward pressing surface S2. When the movable cutting member rotates along the arrow shown in Figure 23 under the drive of the power source, the upward flipping surface S1 is the surface that contacts the garbage. The upward flipping surface S1 can guide the garbage upward over the sorting portion 4211 to achieve the upward flipping of the garbage; when the movable cutting member rotates along the arrow shown in Figure 24 under the drive of the power source, the downward pressing surface S2 is the surface that contacts the garbage. The downward pressing surface S2 can press the garbage downward to facilitate the crushing of the blades located below the sorting portion 4211. In this embodiment, the blades of the movable cutting member include an upper blade 421, a middle blade 422, and a lower blade 423 spaced apart in the vertical direction, and the finishing portion 4211 is disposed on the upper blade 421. The upper blade 421, middle blade 422, and lower blade 423 are staggered in the vertical direction, with the middle blade 422 positioned closer to the downward pressure surface S2 of the finishing portion 4211, and the lower blade 423 positioned closer to the upward flipping surface S1 of the finishing portion 4211. This ensures that garbage that is flipped up and falls off the upward flipping surface S1 is subsequently cut by the middle blade 422, and garbage that is pressed down by the downward pressure surface S2 is subsequently cut by the lower blade 423. The power source is configured to drive the movable cutting member to periodically rotate in alternating forward and reverse directions to crush the garbage, thereby achieving alternating flipping and pressing operations.

[0122] As shown in Figure 27 , the fixed cutting element comprises at least one blade. A blade 42 equipped with a tidying portion 4211, driven by the power source, passes over the upper surface of the blade to shear and shred the waste. Specifically, the upper blade 421 equipped with the tidying portion 4211 not only performs a tidying operation by flipping or pressing the waste upwards or downwards, but also cooperates with the fixed cutting element to shear and shred the waste. In this embodiment, the fixed cutting element comprises an upper blade 61 and a lower blade 62 spaced apart vertically. These blades 61 and 62 can be secured to the sidewall of the chamber 30 by riveting, welding, or the like. The lower blade 62 is spaced apart from the inner bottom surface of the chamber 30. As the movable cutting element rotates under the power source, the upper blade 421 passes over the upper surface of the upper blade 61, the middle blade 422 passes through the gap between the upper and lower blades 61 and 62, and the lower blade 423 passes through the gap between the lower blade 62 and the inner bottom surface of the chamber 30. In this way, a first shearing position is formed between the lower blade 423 and the lower blade 62, a second shearing position is formed between the middle blade 422 and the lower blade 62, a third shearing position is formed between the middle blade 422 and the upper blade 61, and a fourth shearing position is formed between the upper blade 421 and the upper blade 61. These multiple shearing positions are distributed in the vertical direction, which is conducive to cutting and crushing the garbage, and can improve the crushing effect and efficiency. Furthermore, the upper blade 61 and the lower blade 62 are both bent in a step-like manner, that is, the blade includes two planes with a height difference, and the two planes are connected by a curved surface, an inclined surface or a vertical surface. The stepped bending of the blade also has an obstructive effect on long strips of garbage that are horizontal in the garbage, thereby facilitating the blocking of long strips of garbage and achieving the cutting of long strips of garbage. Moreover, the step-like structure can also enhance the structural strength of the blade. Only one of the upper blade 61 and the lower blade 62 can also be set as a step-like bending structure. The shape of the blade 42 matches the blade, specifically, the bottom surface of the upper blade 421 matches the shape of the upper blade 61, the shape of the middle blade 422 matches the shape of the space between the upper blade 61 and the lower blade 62, and the top surface of the lower blade 423 matches the shape of the lower blade 62.

[0123] During use, the stirring motor 45 is started, driving the movable cutting part to rotate, and the blades of the movable cutting part sweep across the fixed cutting part, forming a shear with the fixed cutting part to cut the garbage; during the rotation of the movable cutting part, the sorting part 4211 can flip the garbage up or down, and the garbage after flipping can change its posture, so that the garbage that is not suitable for cutting due to its posture has a chance to be transformed into a posture suitable for cutting, and the garbage after being pressed down can be relatively compact, which is conducive to further cutting and crushing.

[0124] From the above description, it can be seen that the garbage crushing device provided by the present application has a movable cutting part including a plurality of blades 42, and at least one blade 42 is provided with a sorting part 4211. The sorting part 4211 is constructed to be suitable for sorting the garbage in the chamber by flipping up and / or pressing down during the movement of the blade 42. At least one blade 42 is arranged below the sorting part 4211 and is configured to cooperate with the fixed cutting part during the movement to cut off the garbage sorted by the sorting part 4211; such an arrangement allows the garbage to be flipped up and / or pressed down by the sorting part 4211 during the process of crushing the garbage by the movable cutting part, so as to change the posture of the garbage and put the garbage in a posture that is conducive to cutting, thereby improving the crushing effect.

[0125]

Gas purification part

[0126] 28 and 29 , the food waste disposer 100 provided herein includes a gas purification device. The food waste disposer 100 can pulverize, heat, and decompose and ferment food waste to generate fertilizer, and the gas purification device can purify the gas generated by the food waste disposer 100 to eliminate odors.

[0127] The gas purification device is disposed on a substrate 1 having a chamber 30 and is adapted to extract gas from the chamber 30 and discharge it after purification. The gas purification device comprises a filter unit and a drive unit. The filter unit is configured to filter the gas flowing therethrough, and the drive unit is configured to provide power for the gas to flow through the filter unit. The drive unit is disposed downstream of the filter unit in the direction of gas flow, and the drive unit causes the gas to flow through the filter unit in a suctioned manner.

[0128] As shown in Figure 28, specifically, the filter unit includes a box cover 81 and a box body 82. The box cover 81 is mounted on the box body 82, and a filter chamber 820 is formed therein. The filter chamber 820 is provided with a filter material. In this embodiment, the filter material is an adsorbent that can remove odors, such as an activated carbon bag formed by wrapping activated carbon with gauze. The filter chamber 820 is provided with a plurality of blocking portions 821. The blocking portions 821 are configured to cause the gas flowing through the filter chamber 820 to flow in a tortuous manner, thereby increasing the path of the gas flowing through the filter chamber 820, thereby increasing the contact time between the gas and the filter material and improving the filtering effect. In this embodiment, the plurality of blocking portions 821 are a plurality of baffles arranged alternately on the side walls of the box body 82. The baffles divide the filter chamber 820 into a plurality of filter compartments, each of which is provided with an adsorbent that can remove odors. The box body 82 has an air inlet 822 near the top and an air outlet 823 near the bottom, for allowing gas in the chamber 30 to enter the filter cavity 820 through the air inlet 822 and for gas filtered by the filter unit to exit the filter cavity 820 through the air outlet 823. In this embodiment, the air inlet 822 and the air outlet 823 are both a plurality of small circular holes.

[0129] The filter unit is detachably mounted on the base 1, and the base 1 includes a mounting box 83 for mounting the filter unit. The mounting box 83 is provided with an air inlet interface 830 correspondingly connected to the air inlet hole 822 of the filter unit, and an air outlet interface 831 correspondingly connected to the air outlet hole 823 of the filter unit. A chamber air port 801 connected to the air inlet interface 830 is provided on the peripheral side wall of the chamber 30 of the base 1. The chamber air port 801 on the chamber 30, the air inlet interface 830 on the mounting box 83, and the air inlet hole 822 on the box body 82 of the filter unit constitute an air inlet connection port for gas in the chamber 30 to enter the filter unit. An air inlet seal 84 is provided at the air inlet connection port. The air inlet seal 84 is a sealing ring that is inserted into the air inlet interface 830 of the mounting box 83 and is clamped to the edge of the air inlet interface 830. The air inlet interface 830 is protruded from both sides of the air inlet seal 84 to respectively adhere to the periphery of the air inlet hole 822 of the box body 82 of the filter unit and the periphery of the chamber air port 801 to achieve a sealed connection at the air inlet communication port.

[0130] The driving unit 86 is arranged in the base 1, and the filter unit is connected to the driving unit 86 through the air outlet connection port. Specifically, the driving unit 86 is a fan, and the base 1 includes an air guide bracket 861 for installing the fan, and the air outlet connection port connects the filter unit and the air guide bracket 861. In one embodiment, the fan is a vortex fan, which is provided with a volute, and the top surface of the volute forms an air intake, and the side forms an air outlet. The air guide bracket 861 is fixed to the top surface of the volute. On the one hand, the air guide bracket 861 is used to form an air cover channel to guide the airflow in the filter unit to the fan, and on the other hand, it is used for installation between the fan and the base 1. In this embodiment, the volute is connected to the air guide bracket 861 by screws, and the air guide bracket 861 is connected to the mounting box 83 of the base 1 by screws. The air guide bracket 861 has a hood air port that communicates with the air outlet interface 831 of the mounting box 83 and the air outlet hole 823 of the filter unit. The air outlet hole 823, the air outlet interface 831, and the hood air port constitute an air outlet connection for gas from the filter unit to enter the base 1. An air outlet seal 85 is provided at the air outlet connection. The air outlet seal 85 is a sealing ring that is inserted into the air outlet interface 831 of the mounting box 83 and engages with the edge of the air outlet interface 831. The two sides of the air outlet seal 85 protrude from the air outlet interface 831 to respectively adhere closely to the periphery of the air outlet hole 823 of the filter unit and the periphery of the hood air port, thereby achieving a sealed connection at the air outlet connection.

[0131] The air inlet and air outlet ports are both located upstream of the drive unit 86. The airflow driven by the drive unit 86 draws gas inward at these ports. Therefore, even if the ports are not sealed properly, external gas will be drawn into the gas purification device from the poorly sealed areas, without causing unpurified gas inside the gas purification device to leak out from the poorly sealed areas. This reduces sealing requirements and helps prevent the leakage of unpurified gas. In other embodiments, the ports between the filter unit and the base 1 are not limited to the air inlet and air outlet ports. A plurality of ports for gas to flow through may be provided between the filter unit and the base 1. The ports are provided with seals. The ports and seals are located upstream of the drive unit 86.

[0132] The following describes the working process of the gas purification device provided by the present application in conjunction with Figure 29: the drive unit 86 (i.e., the fan) is started, driving the gas in the chamber 30 along the direction of the arrow shown in the figure, through the air inlet connecting port into the exhaust channel 80 to pass through the filter unit; the gas flows in a zigzag manner in the filter unit to fully contact with the adsorbent to enhance the deodorization effect; the gas filtered by the filter unit enters the air guide bracket 861 through the air outlet connecting port, and then flows to the fan installed at the lower end of the air guide bracket 861, and is discharged by the fan through the exhaust port.

[0133] From the above description, it can be seen that the gas purification device provided by the present application has the drive unit 86 arranged downstream of the filter unit in the flow direction of the gas, and the drive unit 86 allows the gas to flow through the filter unit in a sucked manner; such a configuration, on the one hand, avoids the excessively fast airflow from hitting the filter unit, causing the airflow to scatter and affecting the filtration efficiency; on the other hand, for the sealing part located upstream of the drive unit 86, the gas is sucked inward, so even if the sealing part is poorly sealed, the external gas will be sucked from the poorly sealed part into the gas purification device, and the unpurified gas inside the gas purification device will not leak out from the poorly sealed part, thereby reducing the sealing requirements and helping to prevent the leakage of gas that has not yet been purified.

[0134]

Ozone deodorization part

[0135] Referring to Figures 31 to 34 , in another embodiment, the food waste disposer 100 is further connected to a gas purification device 900 with an ozone deodorization function. This gas purification device 900 with an ozone deodorization function can replace the gas purification device described above with reference to Figures 28 and 29 , or can be used simultaneously with the gas purification device described above with reference to Figures 28 and 29 in the food waste disposer 100.

[0136] Referring to Figures 31 to 33 , the gas purification device 900 includes an airflow channel for exhaust gas circulation, thereby purifying and deodorizing the exhaust gas as it flows through the airflow channel. The gas purification device 900 includes an ozone generator 97 and an ozone catalyst 99. The ozone generator 97 includes an ozone generating electrode 971, which is positioned along the exhaust gas flow path in the airflow channel to ionize oxygen in the exhaust gas to produce ozone. The ozone catalyst 99 is positioned within the airflow channel and downstream of the ozone generating electrode 971. After the exhaust gas passes through the ozone generating electrode 971 and generates ozone, it flows toward the ozone catalyst 99 for an ozone-catalyzed oxidation reaction to purify and deodorize the exhaust gas.

[0137] In this embodiment, the airflow channel is formed by splicing together multiple pipes. Specifically, the gas purification device 900 includes an air intake pipe 91, a catalytic reaction pipe 92, an activated carbon filling pipe 93, a first connecting pipe 94, a second connecting pipe 95, and an exhaust pipe 96. The air intake pipe 91, the catalytic reaction pipe 92, the activated carbon filling pipe 93, the first connecting pipe 94, the second connecting pipe 95, and the exhaust pipe 96 are connected to form the airflow channel. The ozone generator 97 is connected to the air intake pipe 91. The mouth of the exhaust pipe 96 is connected to an exhaust device 98 to draw air into the airflow channel.

[0138] The intake pipe 91 is formed with a mounting base 911, and the ozone generator 97 is fixed to the mounting base 911. The intake pipe 91 is provided with an electrode mounting opening 910. The ozone generator 97's generator body 972 is located outside the intake pipe 91, with the ozone generating electrode 971 shielding the electrode mounting opening 910. In one embodiment, the ozone generator 97 is a ceramic ozone generator. Specifically, the ozone generating electrode 971 is a ceramic electrode positioned near the electrode mounting opening 910. Exhaust gas in the airflow channel is ionized by the ceramic electrode to form ozone, which then continues to flow. In this embodiment, the ozone generator body 972 is positioned outside the intake pipe 91, making it easier to install and less susceptible to contamination and damage. The ozone generating electrode 971 shielding the electrode mounting opening 910 prevents outside air from being drawn in through the electrode mounting opening 910, which could reduce exhaust gas extraction efficiency. In other embodiments, the ozone generating electrode 971 may be extended into the air inlet pipe 91, and a sealing structure may be provided between the air inlet pipe 91 and the generator body 972 to prevent air from being sucked in. In other embodiments, the ozone generator 97 may also be other types of ozone generating devices.

[0139] Oxygen in the exhaust gas flowing through the electrode mounting port 910 is ionized by the ozone generating electrode 971 to produce ozone. The exhaust gas mixed with ozone flows through the first connecting pipe 94 to the catalytic reaction tube 92. The intake pipe 91 and the catalytic reaction tube 92 are connected by the first connecting pipe 94, and the first connecting pipe 94 is a curved pipe. The curved pipe can be, for example, L-shaped, U-shaped, or S-shaped. The curved configuration of the first connecting pipe 94 can provide a certain degree of obstruction to the airflow, allowing the ozone and exhaust gas to mix and react before entering the catalytic reaction tube 92 for the ozone catalytic reaction, thereby mixing the ozone with the exhaust gas for primary sterilization, disinfection, and deodorization.

[0140] Please refer specifically to Figure 33 . The cross-sectional area of ​​the catalytic reaction tube 92 is larger than that of the first connecting tube 94, allowing the exhaust gas mixed with ozone to diffuse within the catalytic reaction tube 92, facilitating the full catalytic oxidation reaction of ozone. The ozone catalyst 99 is disposed within the catalytic reaction tube 92. Specifically, the catalytic reaction tube 92 is provided with a heater 923 and a carrier 924. The heater 923 is configured to heat the interior of the catalytic reaction tube 92, while the carrier 924 is configured to support the ozone catalyst 99. The carrier 924 is located downstream of the heater 923, and the ozone catalyst 99 is placed on the carrier 924, also downstream of the heater 923. This allows the exhaust gas to flow through the heater 923 for heating before flowing to the ozone catalyst 99, further facilitating the catalytic oxidation reaction of ozone. In this embodiment, the heater 923 is a heating tube; in other embodiments, the heater 923 can also be a heating wire, a heating plate, or the like. The support member 924 is a partition with a plurality of mesh holes, which is fixed to the inner wall surface of the catalytic reaction tube 92. The support member 924 is a partition with mesh holes, which allows airflow to pass through and facilitates the uniform distribution of the ozone catalyst 99 on the support member 924, thereby improving reaction efficiency. In other embodiments, the support member 924 can also be constructed as a hook, support rod, or other structure that can support the ozone catalyst 99. The ozone catalyst 99 can be a metal oxide catalyst such as titanium dioxide, aluminum oxide, manganese dioxide, etc., or a metal catalyst such as titanium, copper, zinc, iron, nickel, manganese, etc.

[0141] The lower end of the catalytic reaction tube 92 is connected to the first connecting tube 94 via a first bottom cover 921. The upper end of the catalytic reaction tube 92 is connected to the second connecting tube 95 via a first upper cover 922, allowing the gases after the catalytic reaction to be discharged from the catalytic reaction tube 29 for further processing. The catalytic reaction tube 92 has an outlet for exhaust gas to exit the catalytic reaction tube 92. The area of ​​the outlet is smaller than the cross-sectional area of ​​the catalytic reaction tube 92, and a baffle 9221 with a plurality of mesh holes is disposed at the outlet. In this embodiment, the baffle 9221 with a plurality of mesh holes is formed in the central region of the first upper cover 22. The airflow within the catalytic reaction tube 92 enters the second connecting tube 95 through the mesh holes of the baffle 9221. The area of ​​the outlet is smaller than the cross-sectional area of ​​the catalytic reaction tube 92, and the baffle 9221 disposed at the outlet provides a certain degree of airflow blocking, which facilitates the full reaction of the exhaust gas within the catalytic reaction tube 92. Moreover, the baffle 9221 with mesh can also play a filtering role, reducing the dust and the like from entering the activated carbon filling tube 93 through the second connecting tube 95, which is beneficial to reducing the frequency of replacement of the activated carbon.

[0142] The airflow passing through the second connecting pipe 95 enters the activated carbon-filled pipe 93, located downstream of the catalytic reaction pipe 92, for further purification by the activated carbon filled in the activated carbon-filled pipe 93. The second connecting pipe 95 is a curved pipe, which can be, for example, L-shaped, U-shaped, or S-shaped. In this embodiment, the activated carbon-filled pipe 93 has a substantially similar shape to the catalytic reaction pipe 92. It has a second upper cover 931 at its upper end and a second lower cover 932 at its lower end. The middle region between the second upper cover 931 and the second lower cover 932 is provided with mesh holes to provide filtering. Because the airflow entering the activated carbon-filled pipe 93 undergoes initial purification during the ozone and exhaust gas mixing phase and further purification through ozone catalytic oxidation, the gas entering the activated carbon-filled pipe 93 is relatively clean, which helps reduce the frequency of activated carbon replacement. The activated carbon particles in the activated carbon-filled pipe 93 further purify the gas through adsorption and oxidation, converting it into carbon dioxide and water vapor before it is discharged through the exhaust pipe 96. One end of the exhaust pipe 96 is connected to the second bottom cover 932 , and the other end is connected to the exhaust device 98 .

[0143] The working process of the gas purification device 900 provided in the present application is as follows: the exhaust gas to be deodorized is connected to the inlet of the intake pipe 91 of the gas purification device 900; the exhaust device 98 is started, and the exhaust device 98 extracts the air flow in the air flow channel to form a negative pressure in the air flow channel, and the exhaust gas enters through the intake pipe 91; the exhaust gas flows through the ozone generating electrode 971 of the ozone generator 97 and is ionized to produce ozone, and the exhaust gas mixed with ozone enters the catalytic reaction tube 92 through the first connecting pipe 94; the mixed gas is heated, catalyzed, and reacts violently in the catalytic reaction tube 92 to decompose and oxidize into harmless, odorless gas; the reacted gas enters the activated carbon filling tube 93 through the second connecting pipe 95, and is further purified by the activated carbon; finally, it is discharged through the exhaust pipe 96 and the exhaust device 98.

[0144] Please refer to Figure 34, the food waste disposer 100 includes a main unit and the gas purification device 900 as described above. The main unit has an inner barrel (not shown) for accommodating food waste and an outer shell located outside the inner barrel. The main unit has an external interface, and the gas purification device 900 is placed outside the outer shell and connected to the external interface. That is, the gas purification device 900 is connected to the main unit in an external manner, which can facilitate the replacement of consumables such as ozone catalyst 99 and activated carbon, and can also reduce the impact of heat in the gas purification device 900 on the main unit. Of course, in another embodiment, the gas purification device 900 can also be arranged in the main unit. Specifically, the main unit is provided with an inner interface connected to the inner barrel, and the gas purification device 900 is arranged in the outer shell and connected to the inner interface.

[0145] From the above description, it can be seen that the gas purification device 900 and the kitchen waste disposer provided in the present application include an ozone generator 97 and an ozone catalyst 99. The electrodes of the ozone generator 97 ionize the oxygen in the exhaust gas to generate ozone, which can sterilize, disinfect and deodorize the exhaust gas; the exhaust gas mixed with ozone is then subjected to an ozone catalytic oxidation reaction by the ozone catalyst 99 to further decompose and oxidize the harmful and malodorous gases into harmless and odorless gases, so as to enhance the purification and deodorization effect.

[0146] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
