Description

[Technical Field]

[0001] The present invention relates to the field of kitchen waste drying, and more particularly to a kitchen waste dryer. [Background technology]

[0002] Existing food waste treatment methods mainly involve a combination of stirring and grinding with heating and dehydration, or hot air drying, which reduces the moisture content of solid food waste, significantly reducing the volume and weight of food waste, reducing odor, and retaining some organic matter for subsequent composting or energy utilization.

[0003] Existing food waste drying equipment, such as the invention patent with license publication number CN106660085B, provides a compact and versatile weight reduction and volume reduction device and an airflow formation mechanism for such equipment. By exposing wet waste to heated air to dry it, spoilage and odors during storage can be prevented. At the same time, dehydration reduces the weight and volume of the waste. Compared to traditional methods that combine stirring and crushing with heating and dehydration, this drying equipment offers the following advantages: 1. More uniform hot air heating results in a more pronounced dehydration effect. 2. No need to crush solid food waste, which reduces equipment wear and tear. 3. The inner walls of the container do not burn or become sticky during food waste heating, making cleaning easier. 4. Evaporated moisture and odors are effectively filtered through a filter, eliminating odors and preventing environmental pollution. [Prior art documents] [Patent documents]

[0005] However, existing food waste drying equipment still has several drawbacks. First, the bottom of the inner tub of a typical dryer is easily clogged with accumulated garbage, resulting in poor drainage and poor heat exchange efficiency, making it difficult for hot air to penetrate to the bottom of the food waste. Second, the steam generated by the heated and filtered wastewater does not have a precise guidance path, causing disruptions to the steam flow path and low exhaust efficiency. Third, the volume of the food waste container is insufficient, limiting the individual drying capacity and low drying efficiency. Summary of the Invention

[0011] Preferentially, a positioning seat for supporting the filter device is provided at the bottom of the filter device, a through hole connected to the hot air hood is formed in the positioning seat, and the inlet of the filter device is located at the bottom, and the through hole is connected to the inlet at the bottom of the filter device.

[0012] Preferably, a filter tank is provided in the main housing, a filter device is disposed in the filter tank, grooves for holding the filter device are formed on both sides of the upper part of the filter tank, an outlet of the filter device is located at the upper part thereof, an installation groove is provided on the upper surface of the main housing, the installation groove is located at the upper part of the filter tank, a ventilation cover is detachably provided in the installation groove, and an air outlet is provided in the ventilation cover.

[0013] Preferentially, a support plate is provided at the bottom of the main body housing, and a first avoidance hole for avoiding the hot air outlet is provided in the support plate, and steam outlets are provided on both sides of the first avoidance hole.

[0014] Preferentially, the hot air hood has an exhaust port on the side closer to the filter device, a first air guide section formed inside the exhaust port, the top of the first air guide section being open, and a second air guide section formed outside the exhaust port extending toward the filter device, and the second air guide section being connected to the through hole of the positioning seat.

[0015] Preferentially, a temperature sensor is provided in the hot air hood.

[0016] Preferentially, a window cover is connected between the main body housing and the base, and an assembly hole for attaching a support plate is provided on the inner periphery of the window cover.

[0017] Preferentially, an electric control module is further provided in the main body housing, and the motor, the heating coil and the temperature sensor are connected to the electric control module via wires.

[0018] Preferentially, the method further includes a lighting lamp fixed on the support plate, the support plate being provided with a lamp hole for installing the lighting lamp, and the lighting lamp passing through the lamp hole extends to the bottom of the support plate.

[0019] The beneficial effects of the technical solution of this invention are mainly reflected in the following points:

[0020] 1. A motor generates high-speed airflow, which is rapidly heated by the heating ring, and a hot air hood maintains heat and guides air. Because the heating ring's maximum temperature is relatively high, the high-speed airflow passing through the heating ring is rapidly heated, becoming high-speed hot air that is blown axially into the inner cylinder. The high-temperature, high-speed hot air improves the dehydration efficiency and drying effect of food waste. The high-speed hot air blows into the water storage space at the bottom of the inner cylinder, following the gaps between the food waste, forming steam that flows back into the hot air cavity through the steam passage. The residual heat of the steam preheats the hot air cavity, improving the drying efficiency of the subsequent drying process and achieving air circulation in the food waste dryer.

[0021] 2. The drainage grate at the bottom of the inner tube features an upward-protruding anti-blocking support. When food waste is placed inside the inner tube, the anti-blocking support lifts the food waste from the bottom, preventing it from directly blocking the surface of the drainage grate and ensuring that high-speed hot air flows smoothly into the water storage chamber to generate steam. The guide grooves on the outer periphery of the inner tube form multiple downward guide paths between the inner tube and the base, allowing steam in the water storage chamber to be transported directional to the hot air chamber. At the same time, the guide grooves provide steam output space, narrowing the steam passage and increasing the overall volume and capacity of the inner tube.

[0022] 3. The motor continuously exhausts the air inside the hot air chamber, causing the air pressure inside the chamber to be lower than the outside pressure. Therefore, after entering the hot air chamber, steam in the steam passage is not directly exhausted through the air intake, but is instead exhausted back into the hot air hood by the motor. The motor's exhaust port is connected to the hot air hood, increasing the air pressure inside the hood and generating two airflows. Part of the airflow is heated by the heating ring and blown out through the hot air outlet into the inner tube; the other part is blown into the filter device, filtered, and then discharged through the exhaust port. The filter device absorbs odors and sterilizes the exhaust, thereby protecting the environment and ensuring hygiene during use. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0024] In order to more clearly and in detail show the objects, advantages and features of the present invention, the following non-limiting description of a preferred embodiment will be used to illustrate and explain the invention. This embodiment is only a typical example of the application of the technical solution of the present invention. Any technical solution formed by equivalent substitution or equivalent effect transformation falls within the scope of protection claimed by the present invention.

[0025] It should also be noted that in the description of this scheme, terms such as "center," "upper," "lower," "left," "right," "front," "rear," "inner," and "outer" that indicate directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, are used solely for the convenience and simplification of explanation, and do not suggest or imply that the referred-to devices or elements must have a specific orientation or be configured and operated in a specific orientation, and therefore cannot be understood as limitations on the present invention.

[0026] Furthermore, the terms "first" and "second" in this solution are used for descriptive purposes only and should not be construed as suggesting or implying a ranking of importance or as implicitly specifying the number of technical features shown. Thus, a feature designated as "first" or "second" may explicitly or implicitly include one or more of such features. In this invention, "plurality" means two or more unless otherwise defined.

[0027] As shown in Figures 1 to 5, the present invention discloses a food waste dryer comprising a main housing 1 and a base 2 arranged at the bottom of the main housing 1, with an air intake 101 and an exhaust 102 formed in the main housing 1, with outside air flowing into the interior of the food waste dryer through the air intake 101 and air inside the food waste dryer being discharged through the exhaust 102.

[0028] As shown in Figures 3, 10 and 11, this food waste dryer includes an inner drum 3 disposed inside a base 2, a drainage grid provided at the bottom of the inner drum 3, and a plurality of drainage holes 302 formed in the drainage grid for conveniently discharging food waste from the inner drum 3 to the outside, and an upwardly protruding anti-clogging support 301 formed on the upper surface of the drainage grid. The underside of the drainage grid is spaced apart from the inner bottom surface of the base 2, forming a water storage space 10 in this space, through which wastewater from the inner drum 3 flows through the drainage holes 302 into the water storage space 10. The anti-clogging support 301 lifts solid food waste from the inner drum 3 and prevents the food waste from covering and clogging the drainage holes 302 of the drainage grid, ensuring smooth discharge of food waste from the inner drum 3 and ensuring air circulation within the inner drum 3 and the water storage space 10.

[0029] 3 and 10, in one embodiment, support legs 303 that support the inner cylinder 3 are provided at the bottom of the inner cylinder 3. When the inner cylinder 3 is placed in the base 2, the support legs 303 are placed on the inner bottom surface of the base 2, and the lower surface of the drainage grid is spaced apart from the inner bottom surface of the base 2, forming the water storage space 10.

[0030] As shown in FIG. 3 , the outer circumferential surface of the inner cylinder 3 and the inner circumferential surface of the base 2 are spaced apart, and a steam passage 11 is formed in the space. As shown in FIGS. 3 , 10 , and 11 , a plurality of guide grooves 304 are formed on the outer circumferential surface of the inner cylinder 3 from bottom to top. The guide grooves 304 extend upward from the bottom of the inner cylinder 3 and guide and transport steam in the water storage space 10 upward, thereby forming a plurality of guide paths within the steam passage 11. Because the guide grooves 304 provide a space for transporting steam, in some embodiments, the width of the steam passage 11 can be appropriately narrowed to bring the volume of the inner cylinder 3 closer to the internal volume of the base 2, thereby expanding the volume of the inner cylinder 3. This allows the inner cylinder 3 to accommodate more food waste and improve drying efficiency.

[0031] As shown in FIG. 3, the food waste dryer includes a hot air chamber 103 disposed inside the main housing 1, and both the air inlet 101 and the steam passage 11 are connected to the hot air chamber 103. As shown in FIGS. 3 and 7 to 9, a motor 4 is disposed inside the hot air chamber 103, and a hot air hood 5 is attached to the outlet of the motor 4. A heating coil 6 is disposed inside the hot air hood 5, and a hot air outlet 8 connected to the inner cylinder 3 is disposed at the bottom of the hot air hood 5. The heating coil 6 can be disposed at any position between the outlet of the motor 4 and the hot air outlet 8. The inlet of the motor 4 is located in the hot air chamber 103, and the outlet of the motor 4 is connected to the hot air hood 5. Therefore, when the motor 4 is started, negative pressure is generated inside the hot air chamber 103, and air is blown into the hot air hood 5. At this time, because the air pressure inside the hot air hood 5 is higher than the air pressure inside the hot air chamber 103, the air inside the hot air hood 5 enters the hot air hood 5. The hot air hood 5 is equipped with a heating coil 6. The airflow entering the hood 5 is heated by the heating coil 6, forming a high-speed hot air current. This high-speed hot air current flows into the inner cylinder 3 through the hot air outlet 8 and comes into contact with the food waste inside the inner cylinder 3. This high-speed hot air current passes through the gaps between the food waste and reaches the bottom of the inner cylinder 3. It then flows into the water storage space 10 through drainage holes 302 in the drainage grid. The high-speed hot air current comes into contact with the food waste and food waste water in the water storage space 10, transforming into steam. It rises through the steam passage 11 and is guided by the guide grooves 304 of the steam passage 11, forming multiple aligned steam paths around the outer periphery of the inner cylinder 3. It is then directed toward the hot air cavity 103 at the top of the inner cylinder 3. The steam in the hot air cavity 103 is then drawn back into the hot air hood 5 via the motor 4 and heated, thereby achieving air circulation within the food waste dryer.

[0032] As shown in FIGS. 3 to 5, the food waste dryer also includes a filter device 9 disposed within the main housing 1. The inlet of the filter device 9 is connected to the hot air hood 5, and the outlet of the filter device 9 is connected to the exhaust port 102. The motor 4 continuously sends air into the hot air hood 5, increasing the air pressure within the hot air hood 5, and simultaneously blowing air into the inner cylinder 3 and the filter device 9. The air flow that flows into the filter device 9 is filtered and sterilized, and then discharged to the outside of the food waste dryer through the exhaust port 102. In one preferred embodiment, the filter device 9 is a carbon box containing activated carbon.

[0033] As shown in Figures 3, 7, 8, 9, and 10, in some embodiments, the hot air hood 5 has open top and bottom ends, a motor 4 is fixed to the top of the hot air hood 5, and its outlet is located at the top opening of the hot air hood 5. The motor 4 can draw air radially or axially and blow air axially. A heating ring 6 is fixed to the inner periphery of the hot air hood 5, and the opening at the bottom of the hot air hood 5 forms a hot air outlet 8 connected to the inner cylinder 3. In one preferred embodiment, the motor 4, hot air hood 5, heating ring 6, and hot air outlet 8 are all coaxially arranged, allowing air to be blown into the inner cylinder 3 along the axial direction. A steam outlet 12 connected to the steam passage 11 is further provided at the bottom of the hot air chamber 103. The steam outlet 12 is located outside the hot air chamber 5 to prevent steam from directly entering the hot air chamber 5. The steam flow path can be extended, and residual heat from the steam can be used to heat the air in the hot air chamber 103. At the same time, water droplets generated by condensation of steam while flowing through the hot air chamber 103 can return to the steam passage 11 through the steam outlet 12 and then return to the water storage space 10 along the steam passage 11 .

[0034] As shown in FIG. 3 , in some embodiments, a positioning seat 15 for supporting the filter device 9 is provided at the bottom of the filter device 9. In one preferred embodiment, the positioning seat 15 is formed integrally with the main housing 1, and a rubber gasket is provided on the positioning seat 15 to improve the sealing and cushioning properties of the connection between the positioning seat 15 and the filter device 9. A through-hole 23 connected to the hot air hood 5 is formed in the positioning seat 15, and the inlet of the filter device 9 is located at the bottom of the through-hole 23. The through-hole 23 is connected to the inlet at the bottom of the filter device 9. A portion of the airflow within the hot air hood 5 enters the positioning seat 15 through the through-hole 23 and enters the interior of the filter device 9 through the inlet at the bottom of the filter device 9, where it is filtered and disinfected. The air discharged from the outlet of the filter device 9 is discharged to the outside of the food waste dryer through the air outlet 102.

[0035] In some embodiments, a filter tank is provided within the main housing 1, and a filter device is disposed within the filter tank. As shown in FIG. 4 , grooves 21 are formed on both sides of the top of the filter tank for grasping the filter device 9. When the filter device 9 needs to be replaced, a user can grasp both sides of the filter device 9 through the grooves 21 and remove it. The outlet of the filter device 9 is located at its top. As shown in FIGS. 2 and 4 , an attachment groove 20 is formed on the top surface of the main housing 1. The attachment groove 20 is located at the top of the filter tank. A breathable cover 19 is removably attached to the attachment groove 20. In one embodiment, the breathable cover 19 is recessed in the attachment groove 20, and a handle is provided on the top surface of the breathable cover 19. The breathable cover 19 is provided with an air outlet 102. When the filter device 9 needs to be replaced, the breathable cover 19 is first pulled out of the attachment groove 20 using the handle, and then the filter device 9 is removed.

[0036] 3 and 6 , in some embodiments, a support plate 17 is provided at the bottom of the main housing 1, and the support plate 17 is used to support various components inside the main housing 1 and to separate the main housing 1 from the base 2. The support plate 17 is provided with a first avoidance hole 1701 for avoiding the hot air outlet 8, and the support plate 17 is provided with a steam outlet 12, and the steam outlets 12 are provided on both sides of the first avoidance hole 1701.

[0037] As shown in Figure 7, in some embodiments, the hot air hood 5 has an exhaust port 501 on the side closer to the filter device 9. As shown in Figures 7 and 9, a first air guide section 502 is formed inside the exhaust port 501, and the top of the first air guide section 502 is open. Therefore, the air flow blown out from the outlet of the motor 4 enters the first air guide section 502 directly through the top opening of the first air guide section 502 and is guided to the exhaust port 501. A second air guide section 503 extending toward the filter device 9 is formed outside the exhaust port 501. The second air guide section 503 is connected to the through hole 23 of the positioning seat 15 and guides the air flow that has entered the exhaust port 501 to the positioning seat 15, where it flows into the interior of the filter device 9 through the inlet of the filter device 9 and is filtered.

[0038] 3, in some embodiments, a temperature sensor 7 is provided in the hot air hood 5. In one embodiment, the temperature sensor 7 is provided between the motor 4 and the heating coil 6 to monitor the temperature of the air flow entering the heating coil 6 in real time and flexibly adjust the heating temperature of the heating coil 6. In another embodiment, the temperature sensor 7 is provided between the heating coil 6 and the hot air outlet 8 to sense the temperature of the hot air heated by the heating coil 6 in real time.

[0039] 1 to 4 , in some embodiments, a window cover 14 is further connected between the main housing 1 and the base 2, the cross-sectional areas of the base 2 and the inner tube 3 are larger than the cross-sectional area of ​​the main housing 1, the base 2 and the inner tube 3 extend to the outer periphery of the main housing 1, and the window cover 14 is made of a transparent material and covers the area where the base 2 and the inner tube 3 extend to the outside of the main housing 1, allowing the inside of the base 2 and the inner tube 3 to be observed through the window cover 14. The upper part of the window cover 14 is provided with a limiting structure that matches the bottom of the main housing 1, and the bottom of the window cover 14 is provided with a limiting structure that matches the upper part of the base 2. In one embodiment, the bottom of the window cover 14 and the top of the base 2 are respectively provided with matching limiting notches and limiting steps, the top of the window cover 14 is provided with a circular limiting ring, the bottom of the main housing 1 is provided with an annular limiting groove that matches the limiting ring, the inner circumference of the window cover 14 is provided with an assembly hole for attaching the support plate 17, the outer circumference of the support plate 17 is provided with a circular limiting clamp seat that fits into the inner circumference of the assembly hole, and the bottom of the limiting clamp seat is formed with a circular step surface extending toward the outer circumference, which abuts the bottom of the assembly hole and is provided with a plurality of limiting bosses, and the outer circumference of the assembly hole is formed with limiting slots that correspond to the limiting bosses one by one. When the support plate 17 is assembled into the assembly hole, the limiting bosses engage with the limiting slots one by one, connecting the support plate 17 and the window cover 14 to each other. In other embodiments, other existing restrictive structures may be used to connect the window cover 14 to the main housing 1, the window cover 14 to the base, and the window cover to the support plate, but these will not be described in detail here.

The inner cylinder upper cover 18 extends to the outer periphery of the support plate 17 to cover the top of the inner cylinder 3. A second escape hole is provided in the inner cylinder upper cover 18 to escape the hot air outlet 8. The inner cylinder upper cover 18 forms a shield at the top of the inner cylinder 3, preventing the hot air blown out from the hot air outlet 8 from diffusing into the steam passage 11 and preventing steam in the steam passage 11 from directly entering the inner cylinder 3. In this embodiment, the inner cylinder 3 is further provided with an observation port 305 on the side away from the hot air outlet 8. Since the observation port 305 is not blocked by the inner cylinder upper cover 18, the user can observe the conditions inside the inner cylinder 3 through the window cover 14 and the observation port 305.
