Description

Technical Field

[0001] The present invention belongs to the technical field of kitchen waste treatment and relates to an exhaust system of a kitchen waste processor.

Background Art

[0002] A kitchen waste processor is a machine for processing kitchen waste generated in households. Kitchen waste contains various food residues such as leftover rice, fruit peels, and bones. During the process of mixing and processing these different residues inside the machine, strong foul odors are likely to occur. Such foul odors not only simply deteriorate the indoor air environment and cause discomfort to residents, but also attract the breeding of bacteria and the occurrence of pests, becoming a factor harmful to the health of residents. In conventional kitchen waste processors, there has been a problem that the function of effectively filtering and removing foul odor components generated during the waste treatment process is insufficient.

Summary of the Invention

[0003] The object of the present invention is to provide an exhaust system for a kitchen waste processor, and by improving the exhaust system, the air filtration effect is enhanced.

[0004] The exhaust system of the kitchen waste processor of the present invention includes a housing, and an upper casing and a lower casing are detachably provided inside the housing. A filter cavity and an inner cylinder cavity are provided inside the upper casing, and a cover assembly for opening and closing the inner cylinder cavity is installed on the upper casing. An activated carbon box unit is installed inside the filter cavity, and an air intake chamber is provided on the upper casing located on the outer periphery of the filter cavity. An inner cylinder unit for accommodating kitchen waste is installed inside the inner cylinder cavity, and the inlet of the inner cylinder unit communicates with the inner cylinder cavity. An exhaust port is provided on the lower side surface of the inner cylinder unit. A guide cover and a vortex fan are installed inside the lower casing, and a high-pressure region of positive pressure is formed by the vortex fan. As a result, the air flow from the exhaust port is guided to the heating chamber, and the air flow entering the heating chamber is heated by the heating unit installed in the heating chamber. Part of the air flow is circulated back to the inner cylinder cavity by the guide cover, and the remaining air flow flows to the flow splitter plate. At least two air passages are provided in the flow splitter plate. One air passage communicates with the filter cavity where the activated carbon box unit is installed, and the other air passage communicates with the inner cylinder cavity. The intake chamber communicates with the inner cylinder cavity through a communication passage.

[0005] Furthermore, the vortex fan is installed on the fan fixing frame, and the fan fixing frame is provided with a wind guide cover for guiding the discharge of the air flow. An exhaust port communicating with the filter cavity is formed in the wind guide cover. The communication passage extends along the upper arch surface of the wind guide cover.

[0006] Furthermore, the flow splitter plate is composed of an exhaust frame, a left cover and a right cover. The left cover and the right cover are arranged on both the left and right sides of the exhaust frame, and respectively form air passages communicating with the filter cavity. The exhaust frame is provided with an air passage communicating with the inner cylinder cavity.

[0007] Furthermore, the heating unit includes a U-shaped heating ring, and this U-shaped heating ring is attached to the U-shaped heating ring fixing frame. A temperature sensor fixing frame is provided on one side of the U-shaped heating ring fixing frame, and a temperature sensor is installed on the temperature sensor fixing frame.

[0008] Furthermore, the inner cylinder unit is composed of a base, a filter net and a carrier basket. The filter net is installed inside the carrier basket, and divides the internal space of the carrier basket into an upper space and a lower space of the carrier basket. The exhaust port of the inner cylinder unit communicates with the lower space of the carrier basket. The base is installed at the bottom of the inner cylinder cavity, and the carrier basket is arranged on the base.

[0009] Furthermore, the activated carbon box unit is composed of an activated carbon box and an activated carbon box cover, and the space formed by the two is filled with activated carbon. An activated carbon box gasket is installed between the activated carbon box and the bottom of the filter cavity. A first gas vent hole is provided at the bottom of the activated carbon box, and a second gas vent hole is provided at the bottom of the filter cavity. Both the first gas vent hole and the second gas vent hole are located within the area surrounded by the activated carbon box gasket. A third gas vent hole is provided in the activated carbon box cover.

[0010] Furthermore, a ventilation cover is attached to the opening of the filter cavity located above the activated carbon box unit.

[0011] Furthermore, the cover assembly includes an inner lining of the upper cover and the upper cover. The inner lining of the upper cover is installed at the opening of the inner cylinder cavity. One side of the upper cover is hinge-connected to the inner lining of the upper cover, and a hinge spring is provided at the connection part of the two. An upper cover seal gasket is attached to the inner surface of the upper cover. The other side of the upper cover is connected to the inner lining of the upper cover by a hook.

[0012] Furthermore, a control panel electrically connected to a heating unit and a vortex fan is installed inside the upper cover. A light guide column is provided on the control panel, and the light guide column serves to guide the light emitted from the indicator lamp of the control panel to the upper cover.

[0013] Furthermore, a power supply cavity is provided inside the housing, and a power supply box and a power supply cover are arranged inside the power supply cavity. A power supply PCB board is installed inside the power supply box.

[0014] The beneficial effects of the present invention are as follows. The cold air flowing in from the intake chamber is gradually isolated from the hot air in the heating chamber, reducing heat loss. At the same time, the guide cover guides the hot air in the heating chamber back into the inner cylinder cavity, contacts the kitchen waste in the carrier basket to remove moisture, and then settles downward as cold air and returns to the heating chamber. This forms a heat circulation, shortening the circulation cycle and improving the kitchen waste treatment efficiency. By adopting a vortex fan and interlocking it with the one-way ventilation path of the shunt plate, a secondary heat circulation and an exhaust passage are formed. The airflow in the exhaust passage comes into sufficient contact with the activated carbon, removing the odors in the air.

Embodiments for Carrying Out the Invention

[0016] Referring to Figs. 1 to 16, the exhaust system of the kitchen waste processor includes a housing 1, an upper casing 2 and a lower casing 3 detachably installed in the housing 1. This design facilitates maintenance work, cleaning, and component replacement.

[0017] Inside the upper casing 2, a filter cavity 201 and an inner cylinder cavity 202 are provided. An activated carbon box unit 4 is arranged in the filter cavity 201, which serves to adsorb odors and harmful substances in the air flow and purify the air. An air intake chamber 101 for supplying external air flow to the system is provided in the upper casing 2 located outside the filter cavity 201. The upper casing 2 is equipped with a cover assembly 7, which enables the inner cylinder cavity 202 to be easily opened and closed, facilitating the input and removal of kitchen waste into and from the inner cylinder unit 5.

[0018] Inside the inner cylinder cavity 202, a dedicated inner cylinder unit 5 for accommodating kitchen waste is installed. The inlet of the inner cylinder unit 5 communicates with the inner cylinder cavity 202, facilitating the input of kitchen waste. An exhaust port 531 is provided on the lower surface of the inner cylinder unit 5, which serves to dehumidify the kitchen waste.

[0019] Inside the lower casing 3, a guide cover 6 and a vortex fan 81 are installed. When the vortex fan 81 operates, a high-pressure region with positive pressure is formed in a specific area, and this high-pressure region with positive pressure can effectively guide the air flow from the exhaust port 531 of the inner cylinder unit to the heating chamber 108. In this process, the vortex fan 81 inhales external cold air into the kitchen waste treatment area of the inner cylinder unit 5. The air permeates the kitchen waste through convection and transports the moisture to the heating chamber 108.

[0020] Inside the heating chamber 108, a heating unit 82 is installed to heat-treat the airflow flowing into the heating chamber 108. A part of the heat-treated airflow refluxes into the inner cylinder cavity 202 due to the air guiding action of the guide cover 6 and contacts the kitchen waste in the carry basket 53. After depriving the kitchen waste of moisture, it becomes cold air and sinks downward and returns to the heating chamber 108 to form a heat circulation, accelerating the drying process of the kitchen waste, shortening the circulation period, and improving the processing efficiency. Another part of the airflow flows toward the flow splitting plate 83, and at least two air passages are provided on the flow splitting plate 83. One air passage communicates with the filter cavity 201 where the activated carbon box unit 4 is arranged, and the airflow is discharged after being filtered and purified by the activated carbon box unit 4. The other air passage communicates with the inner cylinder cavity 202 to realize the circulation utilization of the airflow by forming a secondary heat circulation.

[0021] Furthermore, the intake chamber 101 communicates with the inner cylinder cavity 202 through a communication passage, enabling fresh external air to smoothly enter the inner cylinder cavity 202 and providing a stable airflow circulation base for the entire exhaust system. The exhaust system of this kitchen waste processor realizes the effective treatment and circulation utilization of the airflow in the kitchen waste treatment process through the above structural design and airflow circulation method.

[0022] Specifically, as an important component in the filter cavity 201 of the exhaust system of this kitchen waste processor, the activated carbon box unit 4 has the following specific structure. The activated carbon box unit 4 is composed of an activated carbon box 41 and an activated carbon box cover 42, and the two form a cavity by an appropriate connection method (common mechanical connection methods such as snap fit and screwing). The cavity is filled with activated carbon, which adsorbs impurities such as odor molecules and harmful gases in the airflow to exert the purification effect of the airflow.

[0023] An activated carbon box gasket 43 is installed between the activated carbon box 41 and the bottom of the filter cavity 201. This gasket serves the functions of sealing and buffering. On the one hand, it prevents air flow from leaking through the gap between the activated carbon box 41 and the bottom of the filter cavity 201, and on the other hand, it can reduce the wear caused by friction between the activated carbon box 41 and the bottom of the filter cavity 201. A first gas vent hole is provided at the bottom of the activated carbon box 41, and a second gas vent hole is provided at the corresponding position at the bottom of the filter cavity 201. Both the first gas vent hole and the second gas vent hole are located within the area surrounded by the activated carbon box gasket 43. Thus, the air flow passes through the area defined by the activated carbon box gasket 43 and undergoes purification treatment by the activated carbon. Furthermore, a third gas vent hole is provided in the activated carbon box cover 42, and the filtered gas is discharged from the above-mentioned third gas vent hole.

[0024] A ventilation cover 44 is installed at the opening of the filter cavity 201 located above the activated carbon box unit 4. The ventilation cover 44 prevents foreign objects from the outside from falling into the filter cavity 201 on the premise of ensuring the normal flow of the air flow within the filter cavity 201, and serves to protect components such as the activated carbon box unit 4.

[0025] In this embodiment, the vortex fan 81 is attached to the fan fixing frame 84, and a wind guiding cover 85 is provided on the fan fixing frame 84. The outer surface of the above-mentioned wind guiding cover 85 presents an arch-shaped structure, and by combining with the guide cover 6, the air flow can be effectively guided.

[0026] Specifically, the wind guiding cover 85 is provided with an exhaust port communicating with the filter cavity 201, and the air flow is guided into the filter cavity 201 and discharged after passing through the filtration by the activated carbon box unit.

[0027] The communication passage extends along the upper arch surface of the air guide cover 85. This design makes full use of the characteristics of the arch-shaped structure, enabling the communication passage to achieve a reasonable layout within a limited space. At the same time, the extension method along the upper arch surface reduces the resistance of the airflow in the communication passage, ensuring that the airflow smoothly flows from the intake chamber to the inner cylinder cavity 202.

[0028] The flow dividing plate in this embodiment is composed of an exhaust frame 831, a left cover 832, and a right cover 833. The exhaust frame 831 serves as the main structural part of the flow dividing plate, undertaking the roles of support and airflow induction. The left cover 832 and the right cover 833 are respectively arranged on the left and right sides of the exhaust frame 831. They cooperate with the exhaust frame to form an air passage communicating with the filter cavity 201, ensuring that a part of the airflow after heat treatment flows into the filter cavity 201 for purification. Furthermore, an air passage communicating with the inner cylinder cavity 202 is also provided in the exhaust frame 831, configured such that the other part of the airflow refluxes to the inner cylinder cavity 202 to form a secondary heat circulation.

[0029] The heating unit 82 in this embodiment is an important component for heat-treating the airflow in the exhaust system of this kitchen waste processor, mainly composed of a U-shaped heating ring 821. The U-shaped heating ring is made of a suitable conductive material. When energized, it generates heat and heats the passing airflow to remove moisture and possible residual odor substances in the airflow. The U-shaped heating ring 821 is attached to the U-shaped heating ring fixing frame 822, and the fixing frame plays a role in firmly supporting and stabilizing the U-shaped heating ring, preventing the influence of displacement and vibration during operation on the heating effect.

[0030] On one side of the U-shaped heating ring fixing frame 822, a temperature sensor fixing frame 823 is provided. The temperature sensor fixing frame 823 provides a highly reliable mounting position for the temperature sensor 824, and its structure can be designed in common mechanical fixing methods such as snap type and screw fixing according to actual needs. The temperature sensor 824 is mounted on the temperature sensor fixing frame 823, monitors the temperature of the heating area in real time, and feeds back the temperature signal to the control system (operation panel). Thereby, the control system adjusts the output of the U-shaped heating ring 821 based on the actual temperature situation to achieve precise temperature control.

[0031] In this embodiment, the inner cylinder unit 5 includes a base 51, a filter net 52, and a carry basket 53. The base 51 is installed at the bottom of the inner cylinder cavity 202 and serves as a support. The carry basket 53 is installed on the base 51 to facilitate the removal and insertion from the inner cylinder cavity 202, enabling the cleaning of kitchen waste. The filter net 52 is installed inside the carry basket 53 and partitions the internal space of the carry basket 53 into an upper space and a lower space of the carry basket. The exhaust port 531 of the inner cylinder unit 5 communicates with the lower space of the carry basket. Driven by the vortex fan, the airflow in the inner cylinder unit 5 enters the lower space of the carry basket downward and is discharged from the exhaust port 531. In this process, the moisture of the kitchen waste is removed. The filter net 52 blocks the kitchen waste and prevents the exhaust port 531 from being clogged.

[0032] The cover assembly 7 is an important component for opening and closing the inner cylinder cavity 202 in the upper casing 2, and is composed of an inner lid lining 71 and an upper lid 72. The inner lid lining 71 is installed at the opening of the inner cylinder cavity 202 and plays the role of positioning and support. One side of the upper lid 72 is hinge-connected to the inner lid lining 71, and a hinge spring 73 is arranged at the connection part of the two. The hinge spring 73 provides appropriate elasticity when the upper lid is opened and closed. When the upper lid 72 opens, it automatically bounces up at a certain angle, and when it closes, it provides a buffering effect to prevent damage caused by excessive force. In addition, an upper lid seal gasket 74 is installed on the inner surface of the upper lid 72. When the upper lid 72 is closed, the upper lid seal gasket 74 closely adheres to the opening edge of the inner cylinder cavity 202, effectively preventing the leakage of abnormal odors and airflows in the inner cylinder cavity 202. The other side of the upper lid 72 is connected to the inner lid lining 71 in a hook-like manner. This connection method is simple and highly reliable, and is designed so that the user can quickly open and close the upper lid 72.

[0033] Inside the upper lid 72, a control panel 102 electrically connected to the heating unit and the vortex fan is installed. The control panel 102 functions as the control core of the entire exhaust system, and precisely controls the temperature of the heating unit and the rotation speed of the vortex fan based on a preset program or user operation. The control panel 102 is provided with a light guide column 103. The light guide column 103 guides the light of the indicator lamp on the control panel 102 to the surface of the upper lid 72, enabling the user to intuitively check the operating status such as during operation, standby, and failure of the exhaust system.

[0034] A dedicated power supply cavity is provided inside the housing 1, and a power supply box 104 and a power supply cover 105 are installed inside the power supply cavity. The power supply box 104 provides a stable installation environment for the power supply PCB board 106. The power supply PCB board 106 arranged inside the power supply box 104 converts the external power supply into appropriate voltage and current for each component of the exhaust system, ensuring the normal operation of the entire exhaust system. The power supply PCB board 106 is electrically connected to a power socket 107.

[0035] The exhaust system of the kitchen waste processor proposed in this embodiment has two modes: cold exhaust and heat circulation, which can meet the requirements of different usage scenarios.

[0036] When the cold exhaust mode is adopted, as shown in FIGS. 4 to 9, external cold air flows in from the air inlets on both sides of the main body (illustrated as a→b in the figure). Due to the rotation of the vortex fan, the air passes through the kitchen waste and is sucked into the vortex fan, then exhausted into the heating chamber and heated by the U-shaped heating ring (illustrated as c→d→e in the figure). The cold air is heated and its temperature rises. Under the guiding action of the guide cover 6, it enters the carrier basket and contacts the kitchen waste to remove moisture (illustrated as f→g in the figure). By repeating the cycle of c→d→e→f→g, the moisture of the kitchen waste is sufficiently removed. The hot air is cooled, guided through the air guiding cover to the activated carbon box unit 4. After the activated carbon adsorbs the odor in the cold air, it is discharged outside the machine, thus achieving the drying and deodorization of the kitchen waste.

[0037] When the heat circulation mode is adopted, as shown in FIGS. 10 to 16, external cold air flows in from the air inlets on both sides of the main body (illustrated as A→B in the figure). Due to the rotation of the vortex fan, the air passes through the kitchen waste and is sucked into the vortex fan, then exhausted into the heating chamber and heated by the U-shaped heating ring (illustrated as C→D→E in the figure). In this heating chamber, the cold air comes into sufficient contact with the surface of the heating ring and its temperature rises. The air expands due to heating and its density decreases. This hot air is guided into the carrier basket by the guiding action of the guide cover 6 and contacts the kitchen waste to remove moisture (illustrated as F→G in the figure). Thus, a heat circulation system of C→D→E→F→G is formed. By repeating this heat circulation, the moisture of the kitchen waste is sufficiently removed. After passing through the air guiding cover and entering the activated carbon box unit 4, it is discharged (illustrated as H→I→J in the figure), thereby obtaining the drying effect of the kitchen waste.

[0038] From the above, in the exhaust system of the kitchen waste processor, the cold air entering from the intake chamber and the hot air in the heating chamber adopt a gradient isolation design to prevent direct contact between the two airflows and minimize heat loss. The guide cover 6 recirculates the hot air heated by the heating unit in the heating chamber to the inner cylinder cavity, and the hot air enters the carry basket and comes into sufficient contact with the kitchen waste. Since the hot air has a low density, it forms an upward airflow, removes the moisture of the kitchen waste during the contact process, the temperature of the hot air itself decreases and changes into cold air, and the cold air with increased density becomes a downward flow and recirculates to the heating chamber. In this way, an efficient heat circulation system is constructed. By this circulation method, the air circulation cycle time in the system is shortened, and the drying efficiency of the kitchen waste is improved.
