Description

Technical Field

[0001] The utility model relates to the technical field of kitchen waste disposers, in particular to a kitchen waste disposer with an improved exhaust mechanism. Background Art

[0002] A food waste disposer stirs and shreds food waste through a stirring and shredding mechanism, and heats and ferments the food waste through a heating device to produce organic fertilizer. However, food waste easily produces a strong odor during the fermentation process, and an exhaust mechanism is required to filter the odor generated by the fermentation through a filter element and then discharge it. The size of the filter element determines the filtering performance and replacement frequency of the filter element. Therefore, the size of the filter element should be increased as much as possible to improve the filtering performance and reduce the replacement frequency. However, since household food waste disposers need to be placed on the desktop, their volume cannot be too large, resulting in large-sized filter elements usually adopting a special-shaped structure, making the cross-section of the filter element large and special-shaped. To ensure the adsorption uniformity of the filter element, the size of the air inlet and air outlet of the filter element needs to be increased. However, the exhaust mechanism only uses a micro fan, and the air inlet size of the micro fan is small, and a certain space is still required for transition. Not only does the size of the food waste disposer not decrease, but it also leads to low utilization rate of the filter element, resulting in waste. In addition, the air inlet and air outlet of the filter element are large in size, and its sealing surface is also large, and the risk of leakage is high. In order to solve the above problems, the existing technology also uses a method of connecting multiple filter elements in series to reduce the filter element cross-section and increase the adsorption utilization rate of the filter element. However, this will cause the air duct to be too long, easily generate noise, and have a complex structure, resulting in space waste. In addition, since the filter element cross-section is reduced, the wind resistance increases, the exhaust volume decreases, and the exhaust effect is reduced. The fan also needs to increase the power load to operate, resulting in poor reliability and stability. Therefore, it is necessary to improve it. Utility Model Content

[0036] The following are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention.

[0037] A kitchen waste disposer with an improved exhaust mechanism, such as Figures 1 to 7As shown, it includes an outer shell 11, an upper cover 2, an inner barrel 3, a heating mechanism 4 and a stirring mechanism. The inner barrel 3 is movably installed inside the outer shell 11, the upper cover 2 is provided on the upper part of the outer shell 11, the heating mechanism 4 is provided inside the outer shell 11 and is located at the bottom or side of the inner barrel 3, the stirring mechanism is provided with a stirring drive component and a stirring knife group, the stirring knife group is rotatably installed inside the inner barrel 3, the stirring drive component is provided inside the outer shell 11 and is transmission-connected with the stirring knife group, the inner shell 11 is provided with a diversion chamber 61, a collection chamber 62 and a mixing chamber 64. The flow cavity 71 and at least two filter elements 8 are movably installed in the interior of the outer shell 11. One side of the diversion cavity 61 is connected with the inner barrel 3, and the other side is connected with the air inlets of the two filter elements 8 respectively. The air outlets of the two filter elements 8 are connected with the collecting cavity 71 respectively. An exhaust hole 111 is opened on one side of the outer shell 11. An exhaust fan 75 is arranged between the collecting cavity 71 and the exhaust hole 111. The air inlet of the exhaust fan 75 is connected with the collecting cavity 71, and the air outlet of the exhaust fan 75 is connected with the exhaust hole 111.

[0038] The exhaust mechanism of a traditional kitchen waste disposer is either to increase the filling amount of activated carbon by using a special-shaped filter element 8, or to set multiple filter elements 8 in series. However, the utilization rate of the special-shaped filter element 8 is poor, and it is difficult for air to pass through the filter element 8 evenly. The multiple filter elements 8 connected in series improve the utilization rate by reducing the cross-sectional size of the filter element 8, but it leads to increased wind resistance, small exhaust volume, poor exhaust effect, increased air duct length, and increased overall machine volume. The utility model connects multiple filter elements 8 in parallel through a diversion chamber 61 and a collecting chamber 71. The diversion chamber 61 diverts the odor in the inner barrel 3 to each filter element 8 at the same time. After filtering, the filter element 8 converges and is discharged through the collecting chamber 71. The parallel filter elements 8 reduce the wind resistance while increasing the total cross-sectional size. Resistance, improve exhaust volume, increase exhaust effect, reduce the power of exhaust fan 75, save energy consumption, and extend the service life of exhaust fan 75; each filter element 8 performs adsorption filtration at the same time, which improves the filtering performance of the filter element 8 and reduces the replacement frequency. When replacing, all of them can be replaced together, without having to replace them one by one at intervals, which is more convenient to use; the diversion chamber 61 and the manifold 71 are respectively arranged at the upper and lower ends of the filter element 8, thereby shortening the length of the entire exhaust channel, improving the exhaust effect, reducing space occupancy, and reducing volume; the exhaust fan 75 evacuates the manifold 71, so that the manifold 71 generates negative pressure, thereby inhaling the odor in the inner barrel 3, and the negative pressure exhaust method can further improve the uniformity of adsorption of the filter element 8;

[0039] Specifically, a filter element seat 7 is provided inside the housing 11, and an upward-opening installation cavity 72 is provided on the upper part of the filter element seat 7, and a collecting cavity 71 is provided at the lower part of the filter element seat 7. A partition 74 is provided between the installation cavity 72 and the collecting cavity 71, and the partition 74 is provided with at least two collecting air inlets 711. Each filter element 8 is movably installed in the installation cavity 72. The filter element 8 includes a sealing cover 81, a filter cartridge 82 and a sealing ring 83. The air inlet of the filter element 8 is provided at the upper part of the sealing cover 81, and the air outlet of the filter element 8 is provided at the lower part of the filter cartridge 82. The sealing cover 81 is snap-connected to the upper part of the filter cartridge 82, and the sealing ring 83 is provided between the sealing cover 81 and the filter cartridge 82. The filter cartridge 82 is filled with activated carbon, and an air outlet sealing ring 84 is provided at the lower part of the filter cartridge 82. The air outlet sealing ring 84 is pressed and fitted with the partition 74, and the air outlet of each filter element 8 is respectively connected to each collecting air inlet 711. The filter element 8 adopts a cylindrical filter element 8. The activated carbon filled inside can be replaced by removing the sealing cover 81 without replacing the entire filter element 8, thereby reducing the cost of consumables. The cylindrical filter element 8 has a simple structure, a small cross-section, and high sealing reliability. The air inlet and air outlet of the filter element 8 can cover the entire cross-section of the filter element 8. The air flows directly from top to bottom and evenly through the activated carbon. It has a simple structure, low cost, and high utilization rate of the activated carbon.

[0040] Specifically, the filter element seat 7 is fixedly installed at the rear part of the shell 11, the exhaust hole 111 is opened on the rear side of the shell 11, and the rear side of the shell 11 is provided with a backward-protruding anti-blocking baffle 113. The rear side of the lower part of the filter element seat 7 is provided with a collecting air outlet 712 connected to the collecting chamber 71, and the exhaust fan 75 is fixedly installed at the outer end of the collecting air outlet 712. The air inlet of the exhaust fan 75 is connected to the collecting air outlet 712. The rear side of the filter element seat 7 is also provided with an exhaust groove 73 with an opening facing backward. The lower end of the exhaust groove 73 is connected to the air outlet of the exhaust fan 75, and the exhaust groove 73 is connected to the exhaust hole 111. The upper end of the exhaust groove 73 is provided with an air guide arc surface 731. The exhaust hole 111 is arranged on the rear side of the shell 11, and the air is discharged backward. When the food waste disposer is operated, the air can be prevented from blowing directly onto the human body, and the exhaust hole 111 can be hidden to improve the aesthetics. When the food waste disposer is placed against the wall or there are soft items such as curtains at the back, the raised anti-blocking baffle 113 prevents the objects or walls from clogging the exhaust hole 111, thereby improving reliability and stability. The odor in the inner barrel 3 passes through the diverter chamber 61, the filter element 8 and the collecting chamber 71 from top to bottom, and is then blown upward into the exhaust slot 73 by the exhaust fan 75, and finally discharged from the exhaust hole 111. In the process of the exhaust fan 75 blowing the air upward from bottom to top, the air impacts the wind guide arc surface 731. Under the action of the wind guide arc surface 731, the wind noise is reduced and the exhaust effect is improved. The exhaust fan 75 adopts a thin turbo fan.

[0041] Specifically, a diverter seat 6 is provided inside the upper cover 2, and a diverter cavity 61 is provided inside the diverter seat 6. A diverter air inlet 611 and at least two diverter air outlets 612 are provided at the lower portion of the diverter seat 6, communicating with the diverter cavity 61. The diverter air inlet 611 is located above and communicates with the inner barrel 3. Each diverter air outlet 612 is located above and communicates with the air inlet of each filter element 8. A diverter sealing cover 62 is provided between each diverter air outlet 612 and the air inlet of each filter element 8. The upper portion of the diverter sealing cover 62 is fixedly mounted to the lower edge of the diverter air outlet 612. By providing the diverter cavity 61 in the upper cover 2, the height of the entire device is further shortened, and the structure is more compact. The diverter sealing cover 62 forms a seal between the filter element 8 and the diverter cavity 61, preventing leakage and improving reliability.

[0042] Specifically, an inner shell 12 is provided in the outer shell 11, and the inner shell 12 is snap-fitted to the upper edge of the outer shell 11. A accommodating chamber 112 is provided between the outer shell 11 and the inner shell 12. The heating mechanism 4, the stirring mechanism and the filter element seat 7 are all provided in the accommodating chamber 112. One side of the upper cover 2 is hinged to the inner shell 12, and the other side is snap-fitted to the inner shell 12. The inner shell 12 is provided with a delivery slot 121 with an upward opening and two filter slots 122. Each filter slot 122 is respectively Inserted in the installation cavity 72, the inner barrel 3 is movably installed in the delivery slot 121, and each filter element 8 is inserted in the corresponding filter slot hole 122 and extends into the installation cavity 72. The lower end of the diverter sealing cover 62 is in contact with the cover plate; the sealing cover 81 is provided with a mounting handle 811, the diverter air outlet 612 is provided with an upwardly protruding semicircular diverter avoidance grille 613 for avoiding the mounting handle 811, and the diverter air inlet 611 is provided with a diverter filter grille 614. A accommodating chamber 112 is formed between the outer shell 11 and the inner shell 12, thereby hiding the internal components, protecting the internal components and playing a role in aesthetics. When replacing the filter element 8, you only need to open the upper cover 2 to hold the mounting handle 811 to pull out the filter element 8 for replacement. There is no need to disassemble the shell externally for replacement, which is more convenient to use.

[0043] Specifically, a water collecting pan is movably installed at the bottom of the outer shell 11, and a drain pipe 76 is provided at the bottom of the filter element seat 7. The upper end of the drain pipe 76 is connected to the collecting chamber 71, and the lower end of the drain pipe 76 is connected to the water collecting pan. A drain valve 77 is provided on the drain pipe 76; since the inner barrel 3 has a certain temperature, the air in the inner barrel 3 has a high water content. After flowing through the diversion chamber 61 and the filter element 8, the temperature continues to drop, and the corresponding saturated humidity also drops, which may cause condensation. Especially in the early stage of the drying stage, more condensed water may appear. The condensed water falling from the filter element 8 falls to the bottom of the collecting chamber 71 due to gravity, and then the condensed water is discharged into the water collecting pan by opening the drain valve 77, preventing the condensed water from entering the exhaust fan 75 and causing the exhaust fan 75 to short-circuit or other faults, thereby improving the service life of the exhaust fan 75 and reducing the failure rate. Since the condensed water has been filtered by the filter element 8, there is no odor.

[0044] When the water collecting pan is opened, the sealing top 771 is pressed against the top of the drain pipe 76, and the drain pipe 76 is opened. When the water collecting pan is opened, the sealing top 771 is pressed against the bottom of the drain pipe 76, and the drain pipe 76 is opened. When the water collecting pan is opened, the sealing top 771 is pressed against the top of the drain pipe 76, and the drain pipe 76 is opened. When the water collecting pan is opened, the sealing top 771 is pressed against the bottom of the drain pipe 76, and the drain pipe 76 is opened.

[0045] The lower end surface of the upper cover 2 is provided with a rim seal 21, which seals against the rim of the inner tub 3. An overflow hole 31 is provided on one side of the upper portion of the inner tub 3. An overflow trough 123 is provided on the outer shell 11, adjacent to the overflow hole 31. An overflow pipe is connected between the overflow trough 123 and the water receiving tray. The inner tub 3 is sealed by the upper cover 2, absorbing the cumulative assembly error of the flip-top structure. External air can only enter the inner tub 3 through the overflow hole 31, ensuring pressure balance during exhaust, unaffected by the gap between the upper cover 2 and the outer shell 11, and improving product consistency. The overflow hole 31 not only balances air pressure during intake but also serves as an overflow. When water overflows the overflow hole 31, it flows into the overflow trough 123, which is located on the inner wall of the dispensing trough 121. The water in the overflow trough 123 then flows into the water receiving tray through the overflow pipe, eliminating the need for a separate overflow structure. This makes the structure more compact and reduces costs.

[0046] Specifically, the upper cover 2 is also provided with a control device, which includes a control circuit and a control panel 22. The control panel 22 is fixedly mounted on the upper portion of the upper cover 2. The control circuit is electrically connected to the control panel 22. A temperature and humidity sensor 63 is provided in the diversion chamber 61. A lid opening sensing switch is provided in the upper cover 2. The lid opening sensing switch, the temperature and humidity sensor 63, the exhaust fan 75, the heating mechanism 4, and the stirring drive assembly are electrically connected to the control circuit respectively. The control panel 22 uses a touch screen or a combination of a screen and buttons. The food waste disposer is controlled through the control panel 22. When exhausting, the temperature and humidity of the air in the inner barrel 3 are detected by the temperature and humidity sensor 63, so as to adjust the power of the heating mechanism 4 and the power of the exhaust fan 75 in real time to achieve the best processing effect. The opening of the upper cover 2 is detected by the lid opening sensing switch, which plays a safety protection role when the upper cover 2 is opened.

[0047] Specifically, the heating mechanism 4 includes a heating plate, a temperature sensing component, and a heating control circuit 41. The heating plate is fixedly mounted within the outer shell 11 and positioned below the inner tub 3. The temperature sensing component is fixedly mounted within the outer shell 11 and abuts against the heating plate. The bottom of the outer shell 11 is provided with a downwardly opening waterproof groove 114, with a sealing plate 115 movably mounted below the waterproof groove 114. The heating control circuit 41 is fixedly mounted within the waterproof groove 114. The temperature sensing component is electrically connected to the heating control circuit 41, and the heating control circuit 41 is electrically connected to the control circuit. The heating control circuit 41 is mounted within the waterproof groove 114, which is separated from the accommodating chamber 112, thereby preventing water vapor from invading the heating control circuit 41 and causing damage to the circuit, thereby improving reliability and stability.

[0048] Specifically, the stirring drive assembly includes a stirring drive motor 51, a lower connector 52, an upper connector 53, and a rotating main shaft. The stirring drive motor 51 is fixedly installed in the housing 11 and is located below the inner barrel 3.

The upper meshing portion meshes with the lower meshing portion. The stirring blade group is fixedly installed on the upper end of the rotating main shaft. The stirring drive motor 51 is electrically connected to the control circuit. The stirring blade group is connected to the stirring drive motor 51 through the upper connector 53 and the lower connector 52, which facilitates the disassembly of the inner barrel 3 for cleaning. The structure is simple and the cost is low. Both the upper meshing part and the lower meshing part are composed of a plurality of raised teeth arranged at intervals along the circumferential direction.
