Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen waste disposers, and in particular to a kitchen waste disposer. Background Technology
[0002] A food waste disposer (also known as a kitchen waste processor or food waste grinder) is an electric device installed under the kitchen sink or used independently. It grinds food waste (such as food scraps, fruit peels, and vegetable leaves) into small particles, which are then flushed down the drain, allowing for immediate waste disposal and reducing the burden of household waste storage and sorting. The core functions of existing food waste disposers include, but are not limited to, physically grinding food waste (such as leftovers, bones, fruit pits, and eggshells) into particles typically less than 5mm in diameter, which are then flushed down the drain, preventing waste accumulation and odors. Its functional structure and working principle include: a cutting system: using a high-speed rotating blade or blunt object (such as hammers or grinding rings) to impact and shear the waste; water flushing: water flow assists in flushing the ground particles to prevent pipe blockage; and a motor drive: typically equipped with a high-torque permanent magnet motor or AC motor.
[0003] During the crushing and mixing process, existing food waste disposers ferment food residues and produce gases with strong odors (such as hydrogen sulfide and ammonia). Traditional designs often lack effective sealing and exhaust gas treatment mechanisms, causing these odorous gases to easily escape into the kitchen environment from the feed inlet, gaps, or direct exhaust outlets, seriously affecting user experience and indoor air quality. Utility Model Content
[0004] Therefore, it is necessary to provide a new type of food waste disposer to address the shortcomings of existing waste gas treatment mechanisms.

The cutting module is located inside the cavity and is rotatably connected to the bottom wall of the cavity. The drive control module is installed in the mounting space between the bottom of the inner shell and the bottom wall, and its output end extends to the bottom of the cavity and drives the cutting module. At the same time, the drive control module is electrically connected to the waste gas treatment module.
[0007] The exhaust gas treatment module includes a duct, a fan, and a filter box. The duct is located on the outer surface of the inner shell sidewall, and the top of the duct is connected to the inner side of the top of the inner shell through an air inlet. The fan is located at the bottom of the duct and is electrically connected to the drive control module. The filter box is located on the adjacent side of the duct and connected to the outer surface of the inner shell sidewall. The end of the duct with the fan is connected to the input end of the filter box through a pipe. The output end of the filter box is connected to the outside of the outer shell.
[0008] In one embodiment, the inner shell is provided with a first mounting part, which is disposed on the outer surface of the side wall of the inner shell corresponding to the filter box. The bottom wall of the first mounting part is connected to the branch pipe to form an exhaust port. Correspondingly, the filter box is fitted into the first mounting part, and the input end of the bottom of the filter box abuts against the bottom wall of the first mounting part to connect to the exhaust port.
[0009] In one embodiment, the aforementioned housing is provided with an avoidance window, which corresponds to the filter box being disposed on the side wall surface of the housing, and the avoidance window connects the inner and outer sides of the housing.
[0010] In one embodiment, the filter box is provided with an air inlet and an air outlet, with the air inlet corresponding to the air outlet located at the bottom of the filter box; the air outlet is located on the side surface of the filter box facing the avoidance window.
[0011] In one embodiment, the filter cartridge is further provided with a handle, which is disposed on the side surface of the filter cartridge facing the avoidance window.
[0012] In one embodiment, the filter box described above is configured as a carbon box.
[0013] In one embodiment, the drive control module includes a drive motor, a bracket, and a tray. The bracket is disposed between the bottom of the inner shell and the bottom plate; the drive motor is mounted on the bottom of the bracket; and the tray is mounted on the top of the bracket. Meanwhile, the top side surface of the tray abuts against the bottom of the cavity.
[0014] In one embodiment, the drive control module further includes a first control board, a second control board, and a third control board; the first control board is disposed in a mounting frame of the base plate; the second control board is mounted on the inner surface of the top wall of the housing; and the third control board is mounted on the outer surface of the top wall of the air duct.
[0015] In one embodiment, the first control board is configured as the main control board to control the start-up, shutdown, and output power of the drive motor and the fan.
[0016] In one embodiment, the outer shell is provided with a second mounting portion, which is disposed on the inner wall surface of the top of the outer shell and forms an annular connection structure; correspondingly, when the inner shell is fitted into the outer shell, the top of the inner shell is fitted and connected to the first mounting portion.
[0017] In one embodiment, the bottom of the cover is provided with a mating part, and correspondingly, the top of the inner shell is provided with a mating groove. When the cover is properly fitted to the outer shell and the inner shell, the mating part is fitted into the mating groove.
[0018] The above-mentioned food waste disposer
[0019] (1) A “closed space” is formed by the cover, inner shell and bottom plate to completely wrap the cavity that generates odor, thus forming the first physical barrier. At the same time, a waste gas treatment module is set up, which is a conveying and filtering structure formed by air duct + fan + filter box. The odor gas in the closed space is actively sucked out and forcibly sent into the filter box for adsorption and purification. The clean gas after treatment is then discharged to the outside, thus forming the second chemical / physical purification barrier, thereby ensuring the effective isolation of the odor gas inside the cavity from the external environment.
[0020] (2) The kitchen waste processor of this utility model uses the interlayer space between the inner shell and the outer shell as the preset installation space, integrates the exhaust gas treatment module (air duct, fan, filter box) in the interlayer, and places the drive control module at the bottom, making full use of the vertical space inside the outer shell, thereby realizing the compact integration of core functions such as crushing, sealing, ventilation, filtration and control, and enhancing the space utilization and independent use of the kitchen waste processor.
[0021] (3) Compared with the passive filtration of traditional kitchen waste processors (such as adding activated carbon sheets at the feed inlet), the kitchen waste processor of this utility model is equipped with a fan at the bottom of the air duct, which is powered and controlled by the drive control module. It actively draws the exhaust gas at the top of the cavity into the air duct through the air inlet. The exhaust gas is forced by the fan to enter the filter box through the branch pipe for full adsorption and filtration treatment, which improves the treatment efficiency. Attached Figure Description

[0033] Please see Figures 1 to 5 This utility model discloses a food waste disposer 1, which includes a cover 10, an outer shell 20, a bottom plate 30, an inner shell 40, and a cavity 50. The cover 10 and the bottom plate 30 are respectively disposed at the top and bottom ends of the outer shell 20. The cover 10 is movably connected to the top end of the outer shell 20 to form a protective, isolating, and sealing structure for the food waste disposer 1. The inner shell 40 is disposed inside the outer shell 20, and the top end of the inner shell 40 corresponds to and cooperates with the cover 10. The cavity 50 is stably housed inside the inner shell 40, and the food waste to be processed is put into the cavity 50 for stirring and crushing. The interlayer space between the inner shell 40 and the outer shell 20 provides a preset installation space; and the sealed space formed by the cover 10, the inner shell 40, and the bottom plate 30 can prevent the exhaust gas (mainly odorous gas) generated during the food waste processing inside the cavity 50 from escaping into the external space and affecting the user experience.
[0034] Based on the above configuration, the food waste disposer 1 also includes a waste gas treatment module 60, a cutting module 70, and a drive control module 80. The waste gas treatment module 60 is disposed within the interlayer between the side wall of the inner shell 40 and the outer shell 20, and its gas input end is connected to the cavity 50, allowing waste gas inside the cavity 50 to be input into the waste gas treatment module 60 for treatment and absorption. The cutting module 70 is disposed inside the cavity 50 and is rotatably connected to the bottom wall of the cavity 50. The drive control module 80 is installed in the mounting space between the bottom end of the inner shell 40 and the bottom wall, and its output end extends to the bottom of the cavity 50 and drives the cutting module 70. Simultaneously, the drive control module 80 is electrically connected to the waste gas treatment module 60 to automatically control the waste gas treatment module 60. Specifically, the exhaust gas treatment module 60 includes a duct 61, a fan 62, and a filter box 63. The duct 61 is located on the outer surface of the side wall of the inner shell 40, and its top end is connected to the inner side of the top of the inner shell 40 through an air inlet a. Thus, gas released from the cavity 50 can be input into the duct 61 from the top of the cavity 50 through the air inlet a. The fan 62 is located at the bottom of the duct 61 and is electrically connected to the drive control module 80. Therefore, the fan 62 can provide power to the duct 61. The internal gas provides the driving force, causing the exhaust gas in the air duct 61 to flow in a directional and constant speed. The filter box 63 is located on the side of the air duct 61 and connected to the outer surface of the side wall of the inner shell 40. One end of the air duct 61, where the fan 62 is located, is connected to the input end of the filter box 63 through a branch pipe 64. Thus, the airflow driven by the fan 62 can be transported to the inside of the filter box 63 through the branch pipe 64 for adsorption and filtration. The output end of the filter box 63 is connected to the outside of the outer shell 20 for the discharge of the treated gas.
[0035] Existing food waste disposers produce gases with strong odors (such as hydrogen sulfide and ammonia) during the crushing and mixing process. Traditional designs often lack effective sealing and exhaust gas treatment mechanisms, causing these odorous gases to easily escape into the kitchen environment from the feed inlet, gaps, or direct exhaust outlets, seriously affecting user experience and indoor air quality. Therefore, to address the above problems, the food waste disposer 1 of this utility model forms a "sealed space" through the cover 10, inner shell 40, and bottom plate 30, completely enclosing the odor-generating cavity 50, thus forming the first physical barrier. At the same time, an exhaust gas treatment module 60 is set up, which is a conveying and filtering structure formed by the air duct 61, fan 62, and filter box 63. It actively draws out the odorous gases in the sealed space and forces them into the filter box 63 for adsorption and purification. The treated clean gas is then discharged to the outside, thus forming the second chemical / physical purification barrier, thereby ensuring the effective isolation of the odorous gases inside the cavity 50 from the external environment. Secondly, the food waste disposer 1 of this invention utilizes the interlayer space between the inner shell 40 and the outer shell 20 as a pre-installed space to integrate the exhaust gas treatment module 60 (air duct 61, fan 62, filter box 63) within this interlayer, and places the drive control module 80 at the bottom, making full use of the vertical space inside the outer shell 20. This achieves a compact integration of core functions such as crushing, sealing, ventilation, filtration, and control, enhancing the space utilization and independence of the food waste disposer 1. Furthermore, compared to the passive filtration of traditional food waste disposers 1 (such as adding activated carbon sheets at the inlet), the food waste disposer 1 of this invention has a fan 62 installed at the bottom of the air duct 61, powered and controlled by the drive control module 80. This fan actively draws the exhaust gas from the top of the cavity 50 into the air duct 61 through the air inlet a. The exhaust gas is then forcibly driven by the fan 62 through the branch pipe 64 into the filter box 63 for thorough adsorption and filtration, improving processing efficiency.
[0036] Furthermore, the inner shell 40 is provided with a first mounting part 41, which is disposed on the outer surface of the side wall of the inner shell 40 corresponding to the filter box 63. The bottom wall of the first mounting part 41 is connected to the branch pipe 64 to form a row of air vents b. Correspondingly, the filter box 63 is fitted into the first mounting part 41, and the input end of the bottom of the filter box 63 is engaged with the bottom wall of the first mounting part 41 to connect to the exhaust vent b, and then to the branch pipe 64. This strengthens the connection stability between the filter box 63 and the inner shell 40 while ensuring that the filter box 63 is connected to the air duct 61.
[0037] Furthermore, the outer casing 20 is provided with a clearance window c, which corresponds to the filter box 63 being disposed on the side wall surface of the outer casing 20, and the clearance window c connects the inner and outer sides of the outer casing 20. Based on this, the user can install and remove the filter box 63 through the clearance window c to clean or replace the filter box 63 in a timely manner.
[0038] Furthermore, the filter box 63 is provided with an air inlet d and an exhaust outlet e. The air inlet d is located at the bottom of the filter box 63, corresponding to the exhaust outlet b. The exhaust outlet e is located on the side surface of the filter box 63 facing the avoidance window c. Thus, the exhaust gas output from the exhaust outlet b can be input into the filter box 63 through the air inlet d, and the odorless gas that has been adsorbed and filtered is discharged to the outside of the food waste processor 1 through the exhaust port.
[0039] Furthermore, in one embodiment, the filter cartridge 63 is also provided with a handle 631, which is disposed on the side surface of the filter cartridge 63 facing the avoidance window c, so as to provide a point of leverage for the user and improve the ease of operation of the filter cartridge 63.
[0040] Furthermore, in one embodiment, the filter box 63 is configured as a charcoal box to ensure the filter box 63's ability to adsorb odors.
[0041] Furthermore, the drive control module 80 includes a drive motor 81, a bracket 82, and a tray 83. The bracket 82 is located between the bottom end of the inner shell 40 and the bottom plate 30. The drive motor 81 is installed at the bottom of the bracket 82. The tray 83 is installed at the top of the bracket 82. At the same time, the top side surface of the tray 83 abuts against the bottom of the cavity 50 to provide stable support for the cavity 50.
[0042] Furthermore, in one embodiment, the drive control module 80 further includes a first control board 84, a second control board 85, and a third control board 86; the first control board 84 is disposed within a mounting frame 31 of the base plate 30; the second control board 85 is mounted on the inner surface of the top wall of the housing 20; and the third control board 86 is mounted on the outer surface of the top wall of the air duct 61. Specifically, in one embodiment, the first control board 84 is configured as the main control board to control the start / stop and output power of the drive motor 81 and the fan 62.
[0043] Furthermore, the outer shell 20 is provided with a second mounting part 21, which is disposed on the inner wall surface of the top of the outer shell 20 and forms an annular connection structure; correspondingly, when the inner shell 40 is fitted into the outer shell 20, the top of the inner shell 40 is fitted and connected to the second mounting part 21, thereby achieving a stable connection between the inner shell 40 and the outer shell 20.
[0044] Furthermore, the bottom of the cover 10 is provided with a mating part 11, and correspondingly, the top of the inner shell 40 is provided with a mating groove f. When the cover 10 is properly fitted to the outer shell 20 and the inner shell 40, the mating part 11 is fitted into the mating groove f, so that the cavity 50 forms a closed space.
[0045] In summary, the food waste disposer disclosed in this utility model forms a "sealed space" through the cover, inner shell, and bottom plate, completely enclosing the odor-generating cavity, thus constituting the first physical barrier. Simultaneously, a waste gas treatment module, namely a conveying and filtering structure consisting of a duct, fan, and filter box, actively draws out the odorous gas from the sealed space and forces it into the filter box for adsorption and purification. The treated clean gas is then discharged to the outside, thus forming a second chemical / physical purification barrier, effectively isolating the odorous gas inside the cavity from the external environment. Furthermore, the food waste disposer of this utility model utilizes the interlayer space between the inner and outer shells as a pre-installed space, integrating the waste gas treatment module (duct, fan, and filter box) within this interlayer, and placing the drive control module below. This fully utilizes the vertical space inside the outer shell, achieving a compact integration of core functions such as crushing, sealing, ventilation, filtration, and control, enhancing the space utilization and operational independence of the food waste disposer. Furthermore, compared to the passive filtration of traditional food waste disposers (such as adding activated carbon sheets at the feed inlet), the food waste disposer of this invention has a fan installed at the bottom of the air duct, which is powered and controlled by the drive control module. The fan actively draws the exhaust gas from the top of the chamber into the air duct through the air inlet. The exhaust gas is forced by the fan to enter the filter box through the branch pipe for thorough adsorption and filtration, thus improving the processing efficiency.
[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
