Description

Technical Field

[0001] The present application belongs to the technical field of kitchen appliances, and in particular relates to an air-cooled cooking appliance. Background Art

[0002] In order to achieve the non-stick effect of food, existing cooking utensils, such as rice cookers, are provided with a non-stick coating on the inner surface of the inner pot. However, in actual use, the non-stick coating will fall off and affect the non-stick effect. When cooking food with an uncoated inner pot, the problem of food sticking to the pot is easy to occur, which reduces the user experience.

[0003] At present, there is an electric rice cooker that achieves a non-stick effect by cooling the inner pot, thereby eliminating the need for a non-stick coating. For example, the prior art discloses a cooking utensil, including a pot cover, a pot body, and an inner pot, wherein a steam discharge port and an air flow inlet and outlet are provided on the outer side of the pot cover, and a steam channel connected to the steam discharge port, an air flow channel connected to the air flow inlet and outlet, and a separation rib are provided inside the pot cover, wherein the separation rib isolates the air flow channel and the steam channel from each other, and the air flow channel is connected to the cooking space of the inner pot through an air vent provided on the inner side of the pot cover, and a fan is provided in the air flow channel, and when the fan is running, it can form a suction force on the external air flow, and the external air is sucked into the air flow channel through the air flow inlet and outlet and sent into the inner pot through the air vent, so as to realize ventilation between the inner pot cooking space and the outside, and cool the food in the pot. However, in actual use, it is found that when the cold air sucked from the outside enters the inner pot through the air vent and blows toward the surface of the food, it will cause the surface of the upper food to become dry and hard, affecting the final cooking effect and the edible taste of the food, and further improvement is needed. Utility Model Content

[0004] The present application provides an air-cooled cooking utensil to solve the technical problem that when the cold air of the existing air-cooled cooking utensil is blown toward the food, the evaporation of water on the surface of the food is intensified, resulting in reduced humidity on the surface of the food, or even drying and hardening the food, thereby affecting the taste of the food.

[0005] The technical solution adopted in this application is:

[0006] A wind-cooled cooking utensil comprises a pot cover and a pot body with a cooking cavity, the pot cover is provided with a flow port connected to the external environment, and an exhaust passage connecting the cooking cavity and the flow port, the pot cover is also provided with a flow passage and an air supply device, the flow passage connects the cooking cavity and the flow port, and the air outlet end of the exhaust passage is located in the flow passage, and the air supply device is used to send the gas in the flow passage into the cooking cavity.

[0007] The air-cooled cooking appliance in the present application also includes the following additional technical features:

[0008] The pot cover comprises a lining cover and an inner cover detachably mounted on the lining cover, and the flow passage is formed between the lining cover and the inner cover.

[0009] The lining cover protrudes upward to form a mixing chamber in the flow passage, and the inner cover is provided with an anti-overflow sleeve extending upward to extend into the mixing chamber. The anti-overflow sleeve is hollow inside to form the exhaust passage therein.

[0010] The air outlet end of the air supply device is configured to discharge air laterally so that air is supplied into the cooking cavity along a radial direction of the cooking cavity.

[0011] The air supply device includes a motor and a fan driven by the motor. The fan is provided with a top air flow inlet and a side air flow outlet. Gas enters from the top air flow inlet and is circumferentially supplied to the cooking cavity from the side air flow outlet.

[0012] The air supply device includes a motor, a fan driven by the motor, and an air guide plate located below the air outlet end of the fan and extending laterally. The fan is provided with a top air flow inlet and a bottom air flow outlet. Gas enters from the top air flow inlet and is blown toward the air guide plate from the bottom air flow outlet, and is laterally delivered into the cooking cavity through the air guide plate.

[0013] The pot cover is provided with a through opening connected to the flow passage, the air supply device comprises a motor and a fan driven by the motor, the fan is located at the through opening, and the pot cover is provided with a wind shielding rib extending downward at the through opening.

[0014] The pot cover is provided with an atomizing device corresponding to the flow passage to atomize the condensed water in the flow passage into water vapor.

[0015] A cooling device is provided in the flow passage or on the side wall of the flow passage to condense the water vapor in the flow passage into water.

[0016] An anti-overflow cover is provided at the flow outlet, and the anti-overflow cover is provided with a plurality of flow holes.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0018] 1. Different from the prior art, the air outlet end of the exhaust channel in the present application is located in the flow channel, so that part of the steam discharged through the exhaust channel can be mixed with the cold air entering from the flow port for heat exchange in the flow channel, and the mixed gas is sent into the cooking cavity along the flow channel by the air supply device. On the one hand, the temperature inside the inner pot and the inner pot can be reduced. The reduction in the temperature of the inner pot allows the high-temperature steam in the cooking cavity to liquefy and form condensed water when it contacts the inner wall of the inner pot, thereby forming a water film on the inner wall of the inner pot to prevent food from sticking to the inner wall of the inner pot. Therefore, there is no need to provide a non-stick coating on the inner wall of the inner pot, and the non-stick effect can be achieved. On the other hand, when the air supply device is running, most of the hot steam discharged from the exhaust channel can be blown back to the cooking cavity, thereby ensuring the humidity of the mixed air sent back to the cooking cavity. While achieving the cooling effect, the humidity on the surface of the food can be guaranteed, so that the upper food can maintain a good cooking taste. Furthermore, the reduction in the internal temperature of the inner pot can cause the hot steam in the inner pot to liquefy into water and fall on the surface of the food, further increasing the humidity on the surface of the food, achieving a moisturizing effect, and ensuring the taste.

[0019] Moreover, in the early stage of cooking and when the air supply device is not in operation, the passage for connecting the cooking cavity and the flow port in the present application has both a flow channel and an exhaust channel, so that during the cooking process, there are two exhaust paths for the steam, one is discharged through the flow port after passing through the exhaust channel, and the other is discharged through the flow port after passing through the flow channel. The increase in the exhaust path helps to improve the exhaust efficiency, thereby improving the anti-overflow effect. In addition, when the air supply device is in operation during the cooking process, the cold air and the hot air are mixed and sent into the cooking cavity. The temperature of the mixed gas is relatively low, and part of the air flow forms a cycle along the cooking cavity, the exhaust channel and the flow channel during the air supply process. When the gas circulates through the cooking cavity, it can suppress the generation of bubbles in the cooking cavity, thereby improving the anti-overflow effect. On the basis of a good anti-overflow effect, it helps to enable the cooking appliance to continuously use the high-power cooking mode, which in turn helps to improve the cooking efficiency, shorten the cooking time, and provide a pleasant user experience.

[0020] 2. As a preferred embodiment of the present application, a flow channel is formed between a lining cover and an inner cover detachably mounted on the lining cover. The inner cover is detachable, which is convenient for a user to thoroughly clean the upper and lower surfaces of the inner cover. At the same time, after the inner cover is removed, a portion of the lining cover that cooperates with the inner cover to form the flow channel is exposed, which is convenient for a user to clean the exposed portion of the lining cover, thereby avoiding the adhesion of soup stains, food, etc. on the inner wall of the flow channel, ensuring the cleanliness of the flow channel, and preventing the generation of odor.

[0021] Furthermore, through the structural design of the lining cover and the inner cover and the assistance of the seal, a flow channel can be formed between the inner cover and the lining cover, thereby eliminating the need to set up an independent piping structure in the pot cover to form the flow channel. This simplifies the structural design of the pot cover, thereby contributing to the lightweight design of the pot cover, and makes it convenient for users to clean the flow channel.

[0022] 3. As a preferred embodiment of the present application, the lining cover protrudes upward to form a mixing chamber in the flow passage, the inner cover is provided with an anti-overflow sleeve extending upward to extend into the mixing chamber, and the exhaust passage is formed in the anti-overflow sleeve. On the one hand, the existence of the mixing chamber provides a mixing space for the hot steam discharged from the anti-overflow sleeve and the cold air sucked from the flow port, which is conducive to the full mixing and heat exchange of the hot steam and the cold air in the mixing chamber, so that the temperature of the gas can be quickly mixed and uniformed. On the other hand, during the cooking process, the anti-overflow sleeve can squeeze and break the bubbles, and the large space formed by the mixing chamber is convenient for the entry of cold air from the outside, so that the bubbles discharged from the anti-overflow sleeve can fully contact and collide with the cold air from the outside in the mixing chamber, which can be conducive to cooling and breaking bubbles, thereby improving the anti-overflow effect and liquefying part of the high-temperature steam into water, thereby increasing the humidity in the flow passage, and then increasing the humidity of the mixed air sent into the cooking cavity.

[0023] 4. As a preferred embodiment of the present application, the air outlet end of the air supply device is configured to discharge air sideways, so that the air is delivered into the cooking cavity along the radial direction of the cooking cavity. Compared with the direct blowing air in method, the side air outlet enables the wind to be delivered in the radial direction. On the one hand, it increases the contact area between the mixed air and the hot steam in the inner pot per unit time, increases the coverage area when the high-temperature steam is liquefied into water and drips onto the surface of the food, and makes the humidity of the upper food more uniform. On the other hand, the mixed air is delivered in the radial direction, which can make part of the air blow toward the inner wall of the inner pot to drive the inner wall of the inner pot to achieve cooling, thereby helping to form a water film inside the inner pot and improving the non-stick effect.

[0024] 5. As a preferred embodiment of the present application, an atomizing device is provided in the pot cover corresponding to the flow channel, and the atomizing device can atomize the condensed water in the flow channel into water vapor, thereby increasing the humidity of the mixed air in the flow channel to ensure the humidity inside the inner pot after air supply, thereby improving the cooking taste of food.

[0025] 6. As a preferred embodiment of the present application, an anti-overflow cover is provided at the exhaust port, and the anti-overflow cover is provided with a plurality of flow holes. The plurality of flow holes divide the anti-overflow cover into a grid-like structure, so as to facilitate the cutting of foam during the exhaust process and improve the anti-overflow effect. In addition, the structure of the grid can also provide a certain barrier to the steam discharged to the outside. On the one hand, it can make part of the steam return and be sent back to the cooking chamber by the air supply device to ensure that most of the steam does not leak out. On the other hand, it can also make part of the steam condense on the grid and drip into the flow channel, which is beneficial to increase the humidity of the mixed air. In addition, the presence of the anti-overflow cover can also protect the flow port to prevent external impurities from entering the exhaust channel and the flow channel through the flow port.

[0050] like Figures 1 to 4 As shown, an air-cooled cooking utensil comprises a pot cover and a pot body with a cooking cavity 101, the pot cover is provided with a flow port 2 communicating with the external environment, and an exhaust passage 51 communicating with the cooking cavity 101 and the flow port 2, the pot cover is further provided with a flow channel 1 and an air supply device, the flow channel 1 communicates with the cooking cavity 101 and the flow port 2, and the air outlet end of the exhaust passage 51 is located in the flow channel 1, and the air supply device is used to send the gas in the flow channel 1 into the cooking cavity 101.

[0051] The pot body in the present application has a cylindrical accommodation space, the inner pot 10 can be freely placed in the accommodation space or taken out from the accommodation space for easy cleaning, the inner pot 10 is provided with a cooking cavity 101, the flow port 2 can be used to discharge the steam flowing out of the cooking cavity 101 through the exhaust channel 51, and can also be used for the entry of external cold air when the air supply device is running, which is not limited here. The exhaust channel 51 can be a short channel formed by a through hole, or a long channel similar to a pipeline, which is not limited here.

[0052] Different from the prior art, the air outlet end of the exhaust channel 51 in the present application is located in the flow channel 1, so that part of the steam exhausted through the exhaust channel 51 can be mixed with the cold air entering from the flow port 2 in the flow channel 1 for heat exchange, and the mixed gas is sent into the cooking cavity 101 along the flow channel 1 by the air supply device. On the one hand, the temperature inside the inner pot 10 and the inner pot 10 can be reduced at the cooking completion stage (for example, the stage after the rice boiling stage is completed, which can be the stewing stage, or the heat preservation stage, or a combination of the two or other stages after the boiling stage). The reduction in the temperature of the inner pot 10 allows the high-temperature steam in the cooking cavity 101 to liquefy and form condensed water when it contacts the inner wall of the inner pot 10, thereby forming a layer of water film on the inner wall of the inner pot 10 to prevent the food from sticking to the inner wall of the inner pot 10, so there is no need to provide a non-stick coating on the inner wall of the inner pot 10. , and a non-stick effect can also be achieved; on the other hand, when the air supply device is running, most of the hot steam exhausted from the exhaust channel 51 can be blown back to the cooking cavity 101, thereby ensuring the humidity of the mixed air sent back to the cooking cavity 101, while achieving a cooling effect, it can ensure the humidity of the surface of the food, so that the upper food can maintain a good cooking taste; furthermore, the reduction in the internal temperature of the inner pot 10 can liquefy the hot steam in the inner pot 10 into water and fall on the surface of the food, further increasing the humidity on the surface of the food, achieving a moisturizing effect, and ensuring the taste.

[0053] Furthermore, in the early stage of cooking and when the air supply device is not in operation (for example, during the heating and boiling stage of rice), the passage for connecting the cooking cavity 101 and the flow port 2 in the present application includes both the flow channel 1 and the exhaust channel 51, so that during the cooking process, there are two exhaust paths for the steam, one is discharged through the flow port 2 after passing through the exhaust channel 51, and the other is discharged through the flow port 2 after passing through the flow channel 1. The increase in the exhaust path helps to improve the exhaust efficiency, thereby improving the anti-overflow effect.

[0054] In addition, when the air supply device is running during the cooking process (for example, the heating and boiling stages of rice, etc.), the cold air and hot air are mixed and sent into the cooking cavity 101. The temperature of the mixed gas is relatively low, and part of the air flow forms a cycle along the cooking cavity 101, the exhaust channel 51 and the flow channel 1 during the air supply process. When the gas circulates through the cooking cavity 101, it can suppress the generation of bubbles in the cooking cavity 101, thereby improving the anti-overflow effect. On the basis of a good anti-overflow effect, it helps the cooking appliance to continuously use a high-power cooking mode, which in turn helps to improve cooking efficiency, shorten cooking time, and provide a pleasant user experience.

[0055] As a preferred embodiment of the present application, refer to Figure 2 and Figure 3 The pot cover includes a lining cover 3 and an inner cover 4 detachably mounted on the lining cover 3 , and a flow passage 1 is formed between the lining cover 3 and the inner cover 4 .

[0056] In one embodiment, the pot cover further includes a pipeline structure located between the lining cover 3 and the inner cover 4 , and the interior of the pipeline structure is hollow to form a flow channel 1 .

[0057] In another embodiment, Figure 2 and Figure 3 As shown, the pot cover includes a sealing member 7 sandwiched between the inner cover 4 and the lining cover 3, the upper part of the sealing member 7 abuts against or is fixedly sealed with the lining cover 3, and the lower part of the sealing member 7 abuts against and seals with the inner cover 4, so as to enclose at least a part of the area of ​​the flow passage 1 between the inner cover 4, the sealing member 7 and the lining cover 3. At least a part of the area of ​​the flow passage 1 in this embodiment is formed by the inner cover 4, the lining cover 3 and the sealing member 7. The inner cover 4 is detachable, which is convenient for the user to thoroughly clean the upper and lower surfaces of the inner cover 4. At the same time, after the inner cover 4 is disassembled, the part of the lining cover 3 used to cooperate with the inner cover 4 to form the flow passage 1 is exposed, which is convenient for the user to clean the exposed part of the lining cover 3. By cleaning the exposed areas of the inner cover 4 and the lining cover 3, the flow passage 1 formed between the two can be cleaned, thereby avoiding the attachment of soup stains, food, etc. on the inner wall of the flow passage 1, ensuring the cleanliness of the flow passage 1, and preventing the generation of odor. Moreover, through the structural design of the lining cover 3 and the inner cover 4 and the assistance of the sealing member 7, a flow channel 1 can be formed between the inner cover 4 and the lining cover 3, thereby eliminating the need to separately set up an independent piping structure in the pot cover to form the flow channel 1. This simplifies the structural design of the pot cover, thereby contributing to the lightweight design of the pot cover, and facilitates the user to clean the flow channel 1.

[0058] As a preferred embodiment of the present application, a mixing chamber 32 is provided in the flow passage 1. The existence of the mixing chamber 32 provides a mixing space for the hot steam discharged from the exhaust passage 51 and the cold air sucked from the flow port 2, which is conducive to the full mixing and heat exchange of the hot steam and the cold air in the mixing chamber 32, so that the temperature of the gas can be quickly mixed and evenly mixed, the humidity in the flow passage 1 is increased, and then the humidity of the mixed air sent into the cooking cavity 101 is increased.

[0059] The specific location of the mixing chamber 32 may be any one of the following embodiments:

[0060] Embodiment 1: The lining cover 3 protrudes upward to form a mixing chamber 32 in the flow channel 1, and the inner cover 4 is provided with a through hole connecting the cooking cavity 101 and the flow channel 1, which constitutes an exhaust channel 51, and the hot steam exhausted through the through hole can enter the mixing chamber 32.

[0061] Example 2: Figure 3As shown, the lining cover 3 protrudes upward to form a mixing chamber 32 in the flow passage 1, and the inner cover 4 is provided with an anti-overflow sleeve 5 extending upward to extend into the mixing chamber 32, and the anti-overflow sleeve 5 is hollow inside to form an exhaust passage 51 therein. During the cooking process, the anti-overflow sleeve 5 can squeeze and break the overflowing bubbles, and the large space formed by the mixing chamber 32 is convenient for the entry of external cold air, so that the bubbles discharged from the anti-overflow sleeve 5 can fully contact and collide with the external cold air in the mixing chamber 32, which can be beneficial to cooling and breaking bubbles, thereby improving the anti-overflow effect and liquefying part of the high-temperature steam into water, thereby increasing the humidity in the flow passage, and then increasing the humidity of the mixed air sent into the cooking cavity.

[0062] Specifically, the lining cover 3 includes a cover body and a convex column 31 which is integrally connected to the cover body and extends upward. The interior of the convex column 31 is hollow to form a mixing chamber 32. One end of the anti-overflow sleeve 5 is installed on the inner cover 4, and the other end extends upward to extend into the interior of the convex column 31. The flow port 2 is located above the mixing chamber 32.

[0063] In the present embodiment 2, the mixing chamber 32 exists as a part of the lining cover 3, which simplifies the composition of the pot cover and is conducive to reducing the processing cost, assembly cost and sealing cost. The existence of the anti-overflow sleeve 5 can guide the hot steam entering the exhaust channel 51 from the cooking cavity 101 upward as much as possible. On the one hand, it can avoid the hot steam discharged from the flow channel from intersecting and colliding too early to affect the exhaust efficiency during the exhaust process. On the other hand, when the air supply device is running for air cooling, the anti-overflow sleeve 5 can guide the hot steam upward into the mixing chamber 32, so that the hot steam and the cold air introduced from the flow port 2 are fully mixed, so that the mixed gas is more uniform and has a better moisturizing effect. Furthermore, the existence of the anti-overflow sleeve 5 can increase the climbing resistance during the steam discharge process, achieve bubble breaking, and improve the anti-overflow effect.

[0064] Preferably, the anti-overflow sleeve 5 is detachably mounted on the inner cover 4 to facilitate operations such as cleaning and replacement of the anti-overflow sleeve 5 .

[0065] As a preferred example of this embodiment 2, Figure 3 As shown, the overflow prevention sleeve 5 and the mixing chamber 32 are arranged eccentrically, so that the cross-sectional area of ​​the flow passage 1 between the mixing chamber 32 and the overflow prevention sleeve 5 is larger on one side than on the other side. The through-port 41 connecting the flow passage 1 and the cooking cavity 101 is located near the side with a larger cross-sectional area. The larger the cross-sectional area, the relatively smaller the pressure during the fluid flow process, thereby facilitating the exhaust during the exhaust process and the air intake during the air cooling process.

[0066] Embodiment 3: The pot cover also includes a valve seat mounted on the lining cover 3, the interior of the valve seat is hollow to form a mixing chamber 32; the inner cover 4 is provided with a through hole for forming an exhaust passage 51, or the inner cover 4 is provided with an anti-overflow sleeve 5 extending upward to extend into the mixing chamber 32, the interior of the anti-overflow sleeve 5 is hollow to form an exhaust passage 51 therein. Different from the above-mentioned embodiments 1 and 2, in this embodiment 3, a valve seat is installed on the lining cover 3, and the interior of the valve seat is hollow to form a mixing chamber 32. Furthermore, in order to prevent steam or mixed air from overflowing from the joint position of the valve seat and the lining cover 3, a sealing structure can be installed at the joint position of the valve seat and the lining cover 3.

[0067] The present application does not limit the location of the air supply device, and it can adopt any one of the following embodiments:

[0068] Embodiment 1: The air supply device is located on a side close to the flow port 2 to blow air into the flow channel 1 .

[0069] Implementation method 2: Figure 3 As shown, the flow passage 1 has a through opening 41 communicating with the cooking cavity 101 , and the air supply device is located on a side close to the through opening 41 to draw air into the flow passage 1 .

[0070] The air outlet end of the air supply device in the above embodiment may adopt any one of the following embodiments:

[0071] Embodiment 1: The air outlet end of the air supply device is configured to discharge air downward, so that the air is delivered to the cooking cavity 101 in a direction parallel to the axial direction thereof.

[0072] Embodiment 2: The air outlet of the air supply device is configured to discharge air sideways, so that air is delivered into the cooking cavity 101 along the radial direction of the cooking cavity 101. Compared with Embodiment 1, the sideways discharge allows the air to be delivered radially, which, on the one hand, increases the contact area between the mixed air and the hot steam in the inner pot 10 per unit time, increases the coverage area when the high-temperature steam is liquefied into water and drips onto the surface of the food, and makes the humidity of the upper food more uniform. On the other hand, the mixed air is delivered radially, which can make part of the air blow toward the inner wall of the inner pot 10 to drive the inner wall of the inner pot 10 to achieve cooling, thereby helping to form a water film inside the inner pot 10 and improving the non-stick effect. Furthermore, the sideways discharge can make the air evenly distributed in the upper part of the cooking cavity 101 to achieve uniform cooling.

[0073] In this embodiment 2, the specific structure of the air supply device can adopt any one of the following examples:

[0074] Example 1: Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the air supply device includes a motor 9 and a fan 8 driven by the motor 9. The fan 8 is provided with a top air flow inlet 83 and a side air flow outlet 84. The gas enters from the top air flow inlet 83 and is circumferentially supplied to the cooking cavity 101 from the side air flow outlet 84.

[0075] Specifically, if Figure 5 and Figure 6 As shown, the fan 8 includes a shell 81, a wind shield 82 is provided at the bottom of the shell 81, and the wind shield 82 is provided with a rotating hole for connecting the motor 9. The interior of the shell 81 is provided with a plurality of fan blades 85 along its circumference. The top of the shell 81 is open to form a top air flow inlet 83, and the side wall of the shell 81 is provided with a plurality of air outlet holes to form a side air flow outlet 84. The air sucked in from the top air flow inlet 83 is discharged through the side air flow outlet 84 to be sent into the cooking cavity 101.

[0076] Example 2: The air supply device includes a motor 9, a fan driven by the motor 9, and an air guide plate located below the air outlet end of the fan and extending laterally. The fan is provided with a top air flow inlet and a bottom air flow outlet. The gas enters from the top air flow inlet and is blown toward the air guide plate from the bottom air flow outlet, and is laterally delivered into the cooking cavity 101 through the air guide plate.

[0077] Compared with the above-mentioned Example 1, in Example 2, since the airflow from the fan flows from the bottom, an air guide plate is added to allow the wind to be laterally sent into the cooking cavity 101 along the air guide plate.

[0078] As a preferred embodiment of the present application, Figure 3 and Figure 4 As shown, the pot cover is provided with a through opening 41 connected to the flow channel 1, the air supply device includes a motor 9 and a fan 8 driven by the motor 9, the fan 8 is located at the through opening 41, and the pot cover is provided with a wind shield 42 extending downward at the through opening 41. The flow channel 1 is connected to the cooking cavity 101 through the through opening 41. There is an assembly gap between the fan 8 and the through opening 41. During the air supply process, the wind in the flow channel 1 has the possibility of entering the cooking cavity 101 through the assembly gap. By adding the wind shield rib 42 extending downward, a slender channel can be formed between the wind shield rib 42 and the fan 8, which increases the wind resistance, thereby greatly reducing the probability of wind entering the cooking cavity 101 from the assembly gap, so that as much wind as possible enters the cooking cavity 101 through the acceleration of the fan 8, so as to enhance the air cooling effect and the effect of preventing overflow and bubble breaking.

[0079] When the fan 8 adopts the structure of Example 1 above, preferably, the lower edge of the wind shield 42 is not lower than the upper edge of the side air flow outlet 84, so as to prevent the wind blown out from the side air flow outlet 84 from hitting the wind shield 42 and causing turbulence at the wind shield 42, thereby ensuring that the mixed air can smoothly enter the cooking cavity 101 and avoiding the aggravation of noise caused by turbulence.

[0080] As a preferred embodiment of the present application, the inner diameter of the opening 41 is larger than the inner diameter of the exhaust channel 51, so that in the exhaust stage and when the air supply device is not running, most of the steam is discharged through the flow channel 1, and part of the steam is discharged through the exhaust channel 51. Because the exhaust path of the flow channel 1 is longer than that of the exhaust channel 51, the resistance loss along the way during the steam discharge process can be increased, thereby improving the overflow prevention effect.

[0081] As a preferred embodiment of the present application, the pot cover is provided with an atomizing device corresponding to the flow channel 1 to atomize the condensed water in the flow channel 1 into water vapor. The atomizing device can atomize the condensed water in the flow channel 1 into water vapor, thereby increasing the humidity of the mixed air in the flow channel 1 to ensure the humidity inside the inner pot 10 after air supply, thereby improving the cooking taste of the food.

[0082] In a specific implementation, the atomizing device is an ultrasonic atomizer. In both the exhaust stage and the air cooling stage, there will be condensed water in the flow channel 1 which is liquefied from high-temperature steam during the flow process. The ultrasonic atomizer uses high-frequency ultrasonic vibration to atomize the condensed water into water vapor, so that the water vapor flows with the mixed gas, which can increase the humidity of the mixed gas. When the mixed gas is sent into the cooking cavity 101, the humidity of the cooking ingredients on the upper layer can be ensured, the cooking taste of the food can be ensured, and the user experience can be improved. Of course, the atomizing device can also be an atomizer that pushes condensed water into the nozzle through compressed air, etc., which is not limited here.

[0083] As a preferred embodiment of this embodiment, a cooling device is provided in the flow channel 1 or on the side wall of the flow channel 1 to condense the water vapor in the flow channel 1 into water. The cooling device can condense the high-temperature steam into water, reduce the emission of the high-temperature steam, thereby reducing the adverse effects of the high-temperature steam on the kitchen environment, etc., and the water condensed from the high-temperature steam can be recycled by the cooking appliance in the present application, thereby reducing the accumulation of condensed water in the flow channel 1.

[0084] In one specific example, the cooling device includes a fan and a heat sink disposed on one side of the fan outlet and located in the flow channel or on the inner wall of the flow channel. In another specific example, the cooling device is a semiconductor cooling sheet disposed in the flow channel or on the inner wall of the flow channel.

[0085] This embodiment does not limit the time node for the operation of the cooling device. In one example, during the exhaust stage and when the air supply device is not operating, the cooling device can be operated to cool the high-temperature steam entering the flow channel 1 so that part of the high-temperature steam condenses into water. During the air cooling stage, when the air supply device and the atomizing device are in operation, the condensed water generated by the cooling device during the exhaust stage can be atomized to facilitate the rapid generation of water vapor, and the condensed water formed by the liquefaction of the high-temperature steam when mixed with the external cold air can be atomized. In another example, during the exhaust stage, the cooling device is not operated, and during the air cooling stage, the cooling device is operated to cool the mixed gas and produce part of the condensed water. On the one hand, the temperature of the mixed gas can be reduced and the air cooling effect of the mixed gas after entering the cooking cavity 101 can be improved. On the other hand, the generation of condensed water can be intensified so that the condensed water can be atomized into water vapor when the atomizing device is in operation. In another example, the cooling device can be operated during both the exhaust stage and the air cooling stage.

[0086] Furthermore, a liquid collecting tank is provided on one side of the inner cover 4 facing the lining cover 3, and the liquid collecting tank can collect the water condensed by the cooling device to prevent it from flowing back into the cooking cavity 101, so that the collected condensed water can be atomized when the atomizing device is subsequently operated. Optionally, the atomizing device has an ultrasonic oscillator, which is arranged at the bottom or side wall of the liquid collecting tank.

[0087] As a preferred embodiment of the present application, Figure 2 , Figure 3 and Figure 7 As shown, an anti-overflow cover 6 is provided at the flow port 2, and the anti-overflow cover 6 is provided with a plurality of flow holes 61. The plurality of flow holes 61 divide the anti-overflow cover 6 into a grid-like structure, so as to facilitate the cutting of foam during the exhaust process and improve the anti-overflow effect. In addition, the structure of the grid can also block the steam discharged to the outside to a certain extent. On the one hand, part of the steam can be returned and sent back to the cooking chamber 101 by the air supply device to ensure that most of the steam does not leak out. On the other hand, part of the steam can also condense on the grid and drip into the flow channel 1, which is beneficial to increase the humidity of the mixed air. In addition, the presence of the anti-overflow cover 6 can also protect the flow port 2 to prevent external impurities from entering the exhaust channel 51 and the flow channel 1 through the flow port 2.

[0088] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0089] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0090] The above is only the embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
