[0041] See also Figure 1 The present application provides a cooking device 1000 , which includes a cooking component 100 and a purification component 200 .
[0042] Specifically, the cooking device 1000 can be an appliance for food processing such as an air fryer, an electric hot pot, or an oven. The food to be cooked is placed in the cooking component 100 for heating, smoking, and other processing. The cooking component 100 is provided with a smoke exhaust passage 10. During the processing of the cooking component 100, food and cooking oil generate a large amount of aerosol under high temperature conditions, and the aerosol can be discharged to the external environment through the smoke exhaust passage 10. The purification component 200 is installed at the smoke exhaust passage 10, and the purification component 200 connects the smoke exhaust passage 10 and the external environment. The purification component 200 can eliminate harmful substances in the aerosol to ensure the safety of the aerosol discharged by the cooking device 1000.
[0043] Aerosols include harmful substances such as carbon monoxide, sulfur dioxide, nitrogen oxides, hydrocarbons, etc. The purification component 200 can catalytically reduce harmful substances in aerosols, converting them into harmless water vapor, nitrogen and carbon dioxide and discharging them into the external environment, thereby achieving the purpose of eliminating harmful substances.
[0044] In the cooking device 1000 of the present application, the cooking component 100 is provided with a smoke exhaust channel 10, and the purification component 200 is arranged at the smoke exhaust channel 10. The aerosol generated by the cooking component 100 during the cooking process can be discharged to the purification component 200 through the smoke exhaust channel 10. The purification component 200 purifies the harmful substances in the aerosol into harmless substances and discharges them to the external environment, thereby preventing the harmful substances from being inhaled by the user, protecting the user's health, and improving the user's experience.
[0045] See also Figure 2In some embodiments, the cooking assembly 100 further includes a smoker 20 and a cooking cavity 30. The smoker 20 is installed in the cooking cavity 30. The cooking cavity 30 is connected to the smoke exhaust passage 10. The smoke exhaust passage 10 can be a space formed in the shell of the cooking cavity 30, or a space extending outside the shell of the cooking cavity 30.
[0046] The cooking device 1000 includes a smoking mode. The user can control the cooking device 1000 to start the smoking mode. The cooking device 1000 controls the smoker 20 to start. The smoker 20 generates aerosol to process the food, so that the food forms a layer of skin with special flavor, thereby improving the taste and mouthfeel of the food.
[0047] Specifically, the smoker 20 can use wood to generate aerosol. For example, the smoker 20 performs incomplete combustion on the wood to generate aerosol. In this incomplete combustion state, the wood decomposes at high temperature to produce cyclic compounds, such as phenols, aldehydes, ketones and other compounds. The compound products further decompose to produce smoke. Then the food is placed on the smoke for smoking. Some soluble components in the smoke will adhere to the surface of the food and react chemically with the food. The compounds generated during the smoking process will adhere to the surface of the food, and these coloring substances will improve the flavor and color of the food.
[0048] Furthermore, the aerosol generated by the smoker 20 circulates to the purification component 200 through the smoke exhaust channel 10 after the food is smoked in the cooking cavity 30. The purification component 200 can catalytically reduce the harmful substances in the aerosol, so that the harmful substances are converted into harmless water vapor, nitrogen and carbon dioxide and discharged to the external environment. For example, the aerosol generated by the smoker 20 includes compounds such as phenols, aldehydes, ketones, alcohols, organic acids, esters and hydrocarbons, among which phenol compounds are the main components. The phenol compounds generate carbon dioxide and water under the high temperature catalysis of the purification component 200.
[0049] In this way, the cooking component 100 also includes a smoker 20 and a cooking cavity 30. The smoker 20 is installed in the cooking cavity 30. The smoker 20 can smoke the food in the cooking cavity 30, so that the cooking device 1000 adds a smoking function. The aerosol generated by the smoker 20 flows to the purification component 200 through the smoke exhaust channel 10. The purification component 200 can eliminate harmful substances in the aerosol and discharge them to the external environment, thereby preventing harmful substances from being inhaled by the user, ensuring the health of the user, and improving the user's experience.
[0050] See also Figure 2 and Figure 3In some embodiments, the smoke exhaust channel 10 may include an exhaust outlet (not shown in the figure), which is used to discharge aerosols. The purification component 20 may be arranged at the exhaust outlet of the smoke exhaust channel 10, and the purification component 200 includes an exhaust pipe 210 and a purifier 220.
[0051] The exhaust pipe 210 is connected to the smoke exhaust channel 10 so that the smoke exhaust channel 10 is connected to the external environment. The exhaust pipe 210 has a first through hole 2121 connected to the outside. The purifier 220 is located in the first through hole 2121 in the exhaust pipe 210 to purify the aerosol in the exhaust pipe 210.
[0052] When the cooking component 100 processes food, the aerosol generated in the cooking component 100 flows into the first through hole 2121 of the exhaust pipe 210 through the smoke exhaust channel 10, and the purifier 220 purifies the harmful substances in the aerosol and outputs it to the outside of the purification component 200 through the first through hole 2121.
[0053] See also Figure 3 In some embodiments, the purifier 220 includes a heating element 221 and a catalyst 222, wherein the catalyst 222 is disposed in the smoke exhaust passage 10, and the heating element 221 may be an electric heating tube, and the heating element 221 is used to heat the catalyst 222, so that the catalyst 222 converts harmful substances in the aerosol into harmless substances. The catalyst 222 may be a three-way catalyst, and the inner surface of the catalyst 222 may be provided with a catalyst coating, and the catalyst coating may be made of a material having a catalytic effect, such as palladium, rhodium, or a cerium-zirconium solid solution.
[0054] The catalyst 222 may be cylindrical, and the portion of the exhaust pipe 210 that accommodates the catalyst 222 is a cylindrical space, and a supporting bottom wall is provided on the upstream side of the catalyst 222, and the supporting bottom wall has air holes;
[0055] The heating element 221 is in the shape of a coil and is installed on the bottom wall of the support. The heating element 210 is located between the catalyst 22 and the bottom wall of the support.
[0056] Furthermore, when the cooking component 100 processes food, the aerosol generated in the cooking component 100 flows into the first through hole 2121 of the exhaust pipe 210 through the smoke exhaust channel 10, and the heating element 221 starts to heat the catalyst 222. The catalyst 222 purifies the harmful substances in the aerosol within a preset temperature range, and then outputs it to the outside of the purification component 200 through the first through hole 2121. For example, the catalyst 222 can catalyze harmful substances such as carbon monoxide, sulfur dioxide, nitrogen oxides, hydrocarbons, etc. in the aerosol to generate harmless carbon dioxide, water vapor and nitrogen. The purified aerosol is discharged to the external environment through the first through hole 2121.
[0057] In some embodiments, the purifier 220 also includes a temperature sensor 223 and a control switch. The temperature sensor 223 is used to detect the temperature of the catalyst 222. The control switch is electrically connected to the temperature sensor 223 and the heating element 221. That is, the control switch can control the heating element 221 to turn on so that the heating element 221 heats the catalyst 222. The control switch can also control the heating element 221 to turn off according to the temperature detected by the temperature sensor 223, thereby stopping heating the catalyst 222.
[0058] Specifically, the optimal operating temperature range of the catalyst 222 is 350 degrees Celsius to 450 degrees Celsius, that is, the preset temperature range is 350 degrees Celsius to 450 degrees Celsius. When the cooking component 100 processes food, the control switch controls the heating element 221 to turn on to heat the catalyst 222. When the temperature sensor 223 detects that the temperature of the catalyst 222 is greater than the preset temperature range, the temperature sensor 223 sends a shutdown signal to the control switch, and the control switch turns off the heating element 221 according to the shutdown signal, so that the heating element 221 stops heating. When the temperature sensor 223 detects that the temperature of the catalyst 222 is less than the preset temperature range, the temperature sensor 223 sends an on signal to the control switch, and the control switch controls the heating element 221 to turn on according to the on signal, so that the heating element 221 can heat the catalyst 222.
[0059] In this way, the purifier 220 can detect the temperature of the catalyst 222 by setting the temperature sensor 223, and by setting the control switch to be electrically connected to the catalyst 222 and the temperature sensor 223, the control switch can control the operation of the catalyst 222 according to the temperature of the catalyst 222 detected by the temperature sensor 223, thereby ensuring that the catalyst 222 remains in the optimal operating temperature range, improving the catalytic efficiency of the catalyst 222, ensuring that the purifier 220 can completely purify the harmful substances in the aerosol, and improving the user experience.
[0060] See also Figure 3 In some embodiments, the exhaust pipe 210 includes a base 211 , a shell 212 , and a connecting bracket 213 .
[0061] The base 211 is installed at the exhaust outlet of the smoke exhaust channel 10, and the shell 212 is installed on the base 211. The shell 212 and the base 211 form an installation cavity 2111. The shell 212 is provided with a first through hole 2121, and the first through hole 2121 connects the installation cavity 2111 with the external environment. The connecting bracket 213 is installed in the installation cavity 2111, and the connecting bracket 213 is used to install the heating element 221 and the catalyst 222, that is, the heating element 221 and the catalyst 222 can be installed on the shell 212 through the connecting bracket 213.
[0062] Furthermore, an air guide channel 2131 is formed in the connecting bracket 213 , the air guide channel 2131 communicates with the smoke exhaust channel 10 and the first through hole 2121 , and the catalyst 222 is installed in the air guide channel 2131 .
[0063] The base 211 can be screwed, welded or riveted to the cooking assembly 100. The housing 212 can be bolted to the base 211. Compared with welding and riveting, the housing 212 and the base 211 are bolted, so that the user can separate the housing 212 from the base 211, which is convenient for repairing and cleaning the connecting bracket 213 installed in the housing 212 and the catalyst 222 installed on the connecting bracket 213.
[0064] In this way, the exhaust pipe 210 can carry the shell 212 by setting a base 211, and the base 211 is installed at the smoke exhaust channel 10. The shell 212 and the base 211 form an installation cavity 2111, so that the smoke exhaust channel 10 is connected with the air guide channel 2123. The aerosol enters the air guide channel 2123 through the smoke exhaust channel 10, is purified by the catalyst 222 installed in the air guide channel 2123, and is discharged to the external environment through the first through hole 2121, thereby achieving purification of the aerosol.
[0065] See also Figure 3 and Figure 4 In some embodiments, the purification component 200 further includes a cover plate 230. The cover plate 230 is connected to the connection bracket 213, and the cover plate 230 is covered on the end of the purifier 220 away from the cooking component 100, that is, the cover plate 230 can be covered on the end of the connection bracket 213 away from the smoke exhaust channel 10, and a second through hole 231 is opened on the cover plate 230. The number of the second through holes 231 can be multiple, for example, the multiple second through holes 231 can be distributed in a mesh shape, so that the cover plate 230 is covered on the purifier 220 in a grate. The aerosol discharged from the smoke exhaust channel 10 flows to the cover plate 230 through the air guide channel 2123 in the connection bracket 213, and is discharged to the external environment through the second through holes 231 of the cover plate 230.
[0066] Furthermore, the cover plate 230 may be made of a high temperature resistant material, and when the aerosol is discharged through the second through hole 231 of the cover plate 230, the cover plate 230 can withstand the impact of the high temperature aerosol. The cover plate 230 may be disposed in the housing 212, that is, the cover plate 230 is disposed on the side of the purifier 220 close to the first through hole 2121, and the aerosol purified by the purifier 220 may flow to the first through hole 2121 through the second through hole 231 of the cover plate 230, and thus be discharged to the external environment.
[0067] It is worth noting that a seal 240 is provided at the connection between the cover plate 230 and the purifier 220, so that the cover plate 230 and the purifier 220 are sealed and connected, that is, all the aerosols purified by the purifier 220 flow to the first through hole 2121 through the second through hole 231 of the cover plate 230, thereby preventing the aerosol from leaking from the connection, causing the aerosol to remain in the shell 212 and pollute the shell 212, and reducing the difficulty of cleaning the exhaust pipe 210.
[0068] In this way, the purification component 200 is covered on the end of the purifier 220 away from the smoke exhaust channel 10 by setting a cover plate 230. The cover plate 230 can withstand the impact of high-temperature aerosol and support the shell 212 to prevent the shell 212 from deforming. A second through hole 231 is opened on the cover plate 230 to communicate with the first through hole 2121 to prevent debris in the external environment from falling into the exhaust pipe 210 through the first through hole 2121 and causing poor aerosol discharge. The second through hole 231 is set on the cover plate 230 to ensure the circulation of aerosol and avoid aerosol backflow.
