[0034] In the related art, conventional embedded cooking appliances are embedded and installed in cabinets. When the cooking appliances are working, water vapor is generated. In order to prevent the water vapor from being retained in the cabinet and causing the cabinet to be damp or dirty, an air guide structure is required to discharge the water vapor generated by the cooking appliances. In the prior art, the water vapor generated when the cooking appliance is cooking is carried out of the cooking cavity by the airflow and flows toward the top and bottom of the cooking appliance respectively. An upper air guide structure is provided on the top of the cooking appliance to guide the airflow to the outside of the cabinet, and a lower air guide structure is provided at the bottom of the cooking appliance to collect condensed water generated by the condensation of the airflow when it encounters cold air. Due to the addition of the upper and lower air guide structures, the material cost and production process of the cooking appliance are increased, resulting in a decrease in the production efficiency of the cooking appliance, and the lower air guide structure blocks the cold air from entering the bottom of the cooking appliance to cool the electrical structure of the cooking appliance, affecting the cooling system of the cooking appliance.

[0035] Reference below Figure 1-Figure 5 A cooking appliance 1 according to an embodiment of the present invention is described.

[0036] like Figure 1As shown, the cooking utensil 1 according to the present invention comprises: an inner pot 40, an outer shell 10, an air guide 20 and an outer frame 30. The inner pot 40 forms a cooking cavity, and an exhaust port 40a communicating with the cooking cavity is provided on the inner pot 40; the outer shell 10 is provided at least partially around the inner pot 40, and the outer shell 10 forms a first air outlet 10a located at the top of the inner pot 40; the air guide 20 is provided between the inner pot 40 and the outer shell 10 and defines a first air guide channel 22a suitable for connecting the first air outlet 10a with the exhaust port 40a; the outer frame 30 is provided with a second air outlet 31a, and the outer frame 30 defines a second air guide channel 32a communicating with the first air outlet 10a and the second air outlet 31a respectively. Specifically, the cooking utensil 1 can be placed in a storage space of a cabinet or a similar cabinet, and the outer frame 30 is installed at the opening end of the storage space to achieve the storage of the cooking utensil 1. The inner pot 40 of the cooking utensil 1 forms a cooking cavity, in which food is cooked. A large amount of water vapor is generated during cooking in the cooking cavity. In order to discharge the water vapor in the cooking cavity in time to prevent the water vapor from condensing and breeding bacteria in the cooking cavity, an air flow outside the cooking utensil 1 can be introduced to discharge the water vapor. In some embodiments, an air inlet channel is formed inside the cooking utensil 1, and the air inlet channel connects the air inlet 10b located at the outer shell 10 and the cooking cavity located at the inner pot 40. Cold air generally enters the cooking utensil 1 through the air inlet 10b and enters the cooking cavity under the action of the fan 60. The cold air mixes with the water vapor in the cooking cavity and flows with the water vapor. At this time, the cold air temperature rises to a humid hot air flow, and the humid hot air flow is discharged from the cooking cavity through the exhaust port 40a of the inner pot 40.

[0037] The outer shell 10 of the cooking utensil 1 is located at the periphery of the inner pot 40 and is formed with a first air outlet 10a. The air guide 20 is located between the inner pot 40 and the outer shell 10 and defines a first air guide channel 22a together with the inner pot 40 and the outer shell 10. The first air guide channel 22a can guide the hot and humid airflow discharged from the exhaust port 40a to the first air outlet 10a. The first air outlet 10a is located at the top of the inner pot 40. The position of the first air outlet 10a is set so that the hot and humid airflow will not contact the cold airflow located in the air inlet channel during the process of flowing along the first air guide channel 22a to the first air outlet 10a, which can prevent the hot and humid airflow from condensing into water droplets during the process of flowing in the first air guide channel 22a. Therefore, there is no need to set up a structure for collecting condensed water, thereby reducing the parts of the cooking utensil 1. A second air guide channel 32a is defined in the outer frame 30, and a second air outlet 31a is also provided on the outer frame 30. The second air outlet 31a can face the outside of the cabinet. The second air guide channel 32a connects the first air outlet 10a located on the outer shell 10 with the second air outlet 31a located on the outer frame 30 to guide the hot and humid airflow blown out of the first air outlet 10a to flow toward the second air outlet 31a. The hot and humid airflow blown out of the second air outlet 31a can be discharged from the cooking utensil 1, thereby achieving the discharge of water vapor in the cooking utensil 1. It can be understood that the first air outlet 10a can also be located on a side of the outer shell 10 away from the air inlet 10b, and the position of the first air outlet 10a is sufficient to ensure that the hot and humid airflow flowing in the first air guide channel 22a does not contact the cold airflow in the cooking utensil 1.

[0038] Water vapor is generated during the process of cooking food in the cooking cavity, and cold air flows into the cooking cavity and mixes with the water vapor to form humid hot air flow, which is discharged from the cooking cavity through the exhaust port 40a on the inner pot 40. The humid hot air flow flows along the first air guide channel 22a toward the first air outlet 10a under the guidance of the air guide member 20, and the humid hot air flow blown out from the first air outlet 10a is guided by the second air guide channel 32a of the outer frame 30 and flows toward the second air outlet 31a, and the humid hot air flow discharged from the second air outlet 31a can be directly discharged to the outside of the cooking appliance 1.

[0039] The cooking utensil 1 according to the present invention guides the hot and humid air flow toward the first air outlet 10a of the outer shell 10 by providing an air guide 20, thereby preventing the hot and humid air flow from contacting with the cold air flow, and further preventing the hot and humid air flow from condensing into water droplets when it encounters cold. Therefore, the cooking utensil 1 does not need to additionally provide a structure for collecting condensed water, thereby reducing the number of parts of the cooking utensil 1, thereby reducing the material cost of the cooking utensil 1, reducing the production process of the cooking utensil 1, and improving the production efficiency of the cooking utensil 1.

[0040] According to some embodiments of the present invention, Figure 4-Figure 5As shown, the outer frame 30 includes an outer frame body 31 and an extension 32. The outer frame body 31 is connected to the outer shell 10, and a second air outlet 31a is formed on the outer frame body 31; the extension 32 is arranged on the outer frame body 31, and the extension 32 defines a second air guide channel 32a. At least part of the extension 32 covers the first air outlet 10a and connects the second air outlet 31a with the first air outlet 10a. Specifically, when the cooking utensil 1 is placed in a cabinet, the outer frame body 31 can cover the open end of the cabinet and cooperate with the outer shell 10 to make the outer frame body 31 cover the gap between the cooking utensil 1 and the cabinet, play a decorative role on the cabinet containing the cooking utensil 1, and ensure the aesthetic appearance. The outer frame body 31 is suitable for serving as the appearance surface of the cooking utensil 1, and the extension 32 is suitable for guiding the flow direction of the hot and humid airflow. The second air outlet 31a is formed on a side surface of the outer frame body 31 facing the outside of the cabinet, and the extension portion 32 is formed on the surface of the outer frame body 31 facing the inside of the cabinet and extends in a direction away from the surface. After the outer frame body 31 is matched with the outer shell 10, at least a portion of the extension portion 32 can cover at least a portion of the surface of the outer shell 10 on which the first air outlet 10a is formed and covers the first air outlet 10a. A gap is formed between at least a portion of the extension portion 32 and at least a portion of the outer shell 10, and the gap is the second air guiding channel 32a. The second air guiding channel 32a connects the first air outlet 10a with the second air outlet 31a. The hot and humid air flow blown out from the first air outlet 10a flows toward the second air outlet 31a under the guidance of the second air guiding channel 32a, and is discharged to the outside of the cabinet by the second air outlet 31a. An extension portion 32 is provided on the outer frame 30 to guide the flow direction of the hot and humid air flow. There is no need to provide a separate air guide structure, which can reduce the number of parts of the cooking appliance 1, reduce the material cost of the cooking appliance 1, reduce the production process of the cooking appliance 1, and improve the production efficiency of the cooking appliance 1.

[0041] In some embodiments, the width of the second air guiding channel 32a gradually increases in a direction toward the second air outlet 31a to increase the flow rate of humid and hot air discharged from the cabinet.

[0042] According to some embodiments of the present invention, Figure 3-Figure 5As shown, a plurality of first air outlets 10 a are disposed on the upper surface of the housing 10 , and the extension portion 32 covers the upper surface of the housing 10 and defines a second air guide channel 32 a with the upper surface of the housing 10 . Specifically, after the outer frame body 31 is matched with the outer shell 10, at least part of the extension part 32 covers the upper surface of the outer shell 10, and at least part of the extension part 32 can cover multiple first air outlets 10a at the same time. At least part of the extension part 32 is spaced from the upper surface of the outer shell 10 to form a second air guiding channel 32a. The second air guiding channel 32a connects the first air outlet 10a with the second air outlet 31a. The humid and hot air flow blown out from the first air outlet 10a flows to the second air outlet 31a under the guidance of the second air guiding channel 32a, so as to guide the humid and hot air flow to the second air outlet 31a, and then control the flow direction of the humid and hot air flow, so that the humid and hot air flow is discharged from the second air outlet 31a to the outside of the cabinet, so as to prevent the humid and hot air flow from directly entering the accommodating cavity of the cabinet and condensing into water droplets when it encounters cold, thereby preventing the cabinet from getting damp.

[0043] According to some embodiments of the present invention, Figure 4-Figure 5 As shown, the lower surface of the housing 10 is provided with a plurality of air guide protrusions 11 extending toward the inner liner 40, and the air guide protrusions 11 are inclined in a direction away from the outer frame body 31. Specifically, at least a portion of the upper surface of the housing 10 is formed with a plurality of first air outlets 10a, and at least a portion of the lower surface of the housing 10 is formed with a plurality of air guide protrusions 11 extending toward the inner liner 40, and the plurality of first air outlets 10a and the plurality of air guide protrusions 11 correspond one to one. The first air guiding channel 22a connects the exhaust port 40a with the first air outlet 10a, wherein the exhaust port 40a is formed in the inner pot 40, at least a portion of the air guiding member 20 is directly opposite to the exhaust port 40a of the inner pot 40, and the first air outlet 10a is formed in the outer shell 10 and is located at the top of the inner pot 40. Therefore, it can be understood that at least a portion of the first air guiding channel 22a is formed between the air guiding member 20 and the inner pot 40, and at least a portion of the first air guiding channel 22a is also formed between the outer shell 10 and the inner pot 40. The air guiding protrusion 11 is suitable for guiding the humid and hot air flow circulating in the first air guiding channel 22a to the first air outlet 10a, thereby prompting the humid and hot air flow to be discharged from the cooking utensil 1.

[0044] According to some embodiments of the present invention, Figure 3As shown, at least a portion of the first air guiding channel 22a gradually increases in cross-sectional area in the direction toward the first air outlet 10a. Specifically, the first air guiding channel 22a connects the exhaust port 40a with the first air outlet 10a, a first portion of the first air guiding channel 22a is formed between the air guiding member 20 and the inner liner 40, and a second portion of the first air guiding channel 22a is formed between the outer shell 10 and the inner liner 40. In some embodiments, the distance between the air guiding member 20 and the inner liner 40 gradually increases in the direction toward the first air outlet 10a, so that the cross-sectional area of ​​the first portion of the first air guiding channel 22a gradually increases in the direction toward the first air outlet 10a. In these embodiments, at least a portion of the air guiding member 20 may be tilted so that the distance between the air guiding member 20 and the inner liner 40 gradually increases in the direction toward the first air outlet 10a, or as Figure 3 As shown, at least a portion of the inner liner 40 is recessed so that the distance between the air guide 20 and the inner liner 40 gradually increases in the direction toward the first air outlet 10a; in other embodiments, the distance between the outer shell 10 and the inner liner 40 gradually increases in the direction toward the first air outlet 10a, so that the cross-sectional area of ​​the second portion of the first air guide channel 22a gradually increases in the direction toward the first air outlet 10a. In these embodiments, at least a portion of the outer shell 10 may be protruded in a direction away from the inner liner 40 so that the distance between the outer shell 10 and the inner liner 40 gradually increases in the direction toward the first air outlet 10a, or at least a portion of the inner liner 40 may be recessed so that the distance between the outer shell 10 and the inner liner 40 gradually increases in the direction toward the first air outlet 10a. Preferably, at least a portion of the inner pot 40 is recessed so that the distance between the air guide member 20 and the inner pot 40 gradually increases in the direction toward the first air outlet 10a, so as to guide the hot and humid airflow in the first air guide channel 22a to flow toward the first air outlet 10a, thereby causing the hot and humid airflow to be discharged from the cooking utensil 1.

[0045] According to some embodiments of the present invention, Figure 2As shown, the air guide 20 includes an air guide body 21 and a flange, the air guide body 21 is arranged at a distance on one side of the inner liner 40 and faces the exhaust port 40a; the flange is formed on at least part of the outer periphery of the air guide body 21, and the flange, the air guide body 21 and at least part of the surface of the inner liner 40 define a first air guide channel 22a. Specifically, the exhaust port 40a is formed in the inner liner 40, the air guide body 21 is arranged at one side of the inner liner 40 and is arranged at a distance from the inner liner 40 to form a first part of the first air guide channel 22a, and the air guide body 21 faces the exhaust port 40a of the inner liner 40 to guide the hot and humid airflow discharged from the exhaust port 40a to the first air outlet 10a. The flange is formed on at least part of the periphery of the air guide body 21 and is connected to the inner liner 40 to fix the air guide body 21 to the inner liner 40. At this time, the flange, the air guide body 21 and at least part of the surface of the inner liner 40 define a first part of the first air guide channel 22a. The flange, the air guide body 21 and at least part of the surface of the inner liner 40 limit the flow direction of the humid and hot airflow, so that the humid and hot airflow discharged from the exhaust port 40a can only flow along the first air guide channel 22a to the first air outlet 10a, thereby controlling the flow direction of the humid and hot airflow, guiding the humid and hot airflow to directly discharge from the cabinet, and reducing the risk of the humid and hot airflow condensing into water droplets when encountering cold airflow.

[0046] According to some embodiments of the present invention, Figure 2As shown, the flange includes a side flange 221, a bottom flange 222 and a top flange 223, there are two side flanges 221 and they are respectively arranged on both sides of the air guide body 21 in the width direction; the bottom flange 222 is arranged at the bottom of the air guide body 21 and the two ends of the bottom flange 222 are respectively connected to the two side flanges 221; the top flange 223 is arranged at the top of the air guide body 21 and one end of the top flange 223 is connected to one of the side flanges 221, and the other end of the top flange 223 is spaced apart from the other one of the side flanges 221 to form an air guide gap 22b, and the air guide gap 22b is connected to the first air outlet 10a. Specifically, side flanges 221 are formed on both sides of the air guide body 21 in the width direction. The side flanges 221 and the air guide body 21 allow the hot and humid airflow discharged from the exhaust port 40a to flow only along the extension direction of the air guide body 21. The bottom flange 222 is located at the bottom of the air guide body 21 and is connected to the two side flanges 221. The bottom flange 222 blocks the airflow flowing along the air guide body 21 and toward the bottom of the air guide body 21, so that the hot and humid airflow can only flow along the air guide body 21 and toward the top of the air guide body 21. The top flange 223 is suitable for being fixedly matched with the inner liner 40 to fix the air guide 20 to the inner liner 40. To ensure smooth airflow in the first air guide channel 22a, the top flange 223 and one of the side flanges 221 are spaced to form an air guide gap 22b. The airflow channel between the exhaust port 40a and the air guide gap 22b is the first part of the first air guide channel 22a, and the airflow channel between the air guide gap 22b and the first air outlet 10a is the second part of the first air guide channel 22a. The bottom flange 222 provided on the air guide body 21 blocks the airflow in the first air guide channel 22a from flowing toward the bottom of the air guide body 21, so as to limit the flow direction of the humid and hot airflow.

[0047] According to some embodiments of the present invention, Figure 2 As shown, an extension plate 211 is formed on the air guide body 21, and the extension plate 211 is arranged at the air guide gap 22b and extends toward the first air outlet 10a. Specifically, the air guide 20 is located in the gap between the outer shell 10 and the inner liner 40, and the air guide 20 is connected to the inner liner 40, and the air guide 20 and the inner liner 40 are spaced to form a first part of the first air guide channel 22a. In some embodiments, due to structural differences, a gap is also formed between the air guide 20 and the outer shell 10, and the extension plate 211 is suitable for guiding the airflow flowing from the air guide gap 22b to the second part of the first air guide channel 22a to flow toward the first air outlet 10a, so as to prevent the hot and humid airflow from flowing along the gap between the air guide 20 and the outer shell 10, thereby preventing the hot and humid airflow from condensing into water droplets when it encounters cold.

[0050] In some embodiments, the support leg 51 can be made of plastic material, which is simple to manufacture and has low cost.

[0051] In some embodiments of the present invention, the cooking utensil 1 comprises an inner pot 40, an outer shell 10, an air guide 20, an outer frame 30, a bottom plate 50 and a fan 60. The cooking utensil 1 can be placed in a storage space of a cabinet or a similar cabinet. The outer frame 30 comprises an outer frame body 31 and an extension 32. The outer frame body 31 covers the open end of the cabinet and is connected with the outer shell 10 to cover the gap between the cooking utensil 1 and the cabinet. The outer frame 30 is installed at the open end of the storage space. The inner pot 40 forms a cooking cavity. The inner pot 40 is provided with an exhaust port 40a connected with the cooking cavity. The outer shell 10 is located at the periphery of the inner pot 40 and is formed with an air inlet 10b and a first air outlet 10a. The air inlet 10b and the cooking cavity are connected through an air inlet channel. The air guide 20 is located between the inner pot 40 and the outer shell 10 and defines a first air guide channel 22a together with the inner pot 40 and the outer shell 10. The first air outlet 10a is located at the top of the inner pot 40. The second air outlet 31a is formed on a side surface of the outer frame body 31 facing the outside of the cabinet, and the extension part 32 is formed on the surface of the outer frame body 31 facing the inside of the cabinet and extends in a direction away from the surface. After the outer frame body 31 is matched with the shell 10, at least part of the extension part 32 covers the upper surface of the shell 10, and at least part of the extension part 32 can cover multiple first air outlets 10a at the same time. At least part of the extension part 32 is spaced from the upper surface of the shell 10 to form a second air guide channel 32a, and the second air guide channel 32a connects the first air outlet 10a with the second air outlet 31a, and the width of the second air guide channel 32a gradually increases in the direction toward the second air outlet 31a. At least part of the upper surface of the shell 10 is formed with multiple first air outlets 10a, and at least part of the lower surface of the shell 10 is formed with multiple air guide protrusions 11 extending toward the inner liner 40, and the multiple first air outlets 10a and the multiple air guide protrusions 11 correspond to each other. At least part of the inner liner 40 is recessed so that the distance between the air guide 20 and the inner liner 40 gradually increases in the direction toward the first air outlet 10a. The air guide 20 includes an air guide body 21 and a flange. The air guide body 21 is directly opposite to the exhaust port 40a of the inner liner 40. Side flanges 221 are formed on both sides of the air guide body 21 in the width direction. The side flanges 221 and the air guide body 21 allow the hot and humid airflow discharged from the exhaust port 40a to flow only along the extension direction of the air guide body 21. The bottom flange 222 is located at the bottom of the air guide body 21 and is connected to the two side flanges 221 to block the airflow flowing along the air guide body 21 and flowing toward the bottom of the air guide body 21. An extension plate 211 is formed on the air guide body 21 and is arranged at the air guide gap 22b and extends toward the first air outlet 10a. The bottom plate 50 is disposed at the bottom of the inner container 40 and is formed with a plurality of heat dissipation holes 50 a . A plurality of supporting legs 51 are also disposed on the bottom surface of the bottom plate 50 .

[0052] Water vapor is generated during the cooking process in the cooking cavity. The fan 60 works, and a cold airflow enters the cooking appliance 1 through the air inlet 10b and the heat dissipation holes 50a and can enter the cooking cavity along the air inlet channel. The cold airflow enters the cooking cavity and mixes with the water vapor to form a humid hot airflow. The humid hot airflow is discharged from the cooking cavity through the exhaust port 40a and flows toward the first air outlet 10a along the first air guide channel 22a under the guidance of the air guide member 20. The humid hot airflow blown out from the first air outlet 10a is guided by the second air guide channel 32a of the outer frame 30 and flows toward the second air outlet 31a. The humid hot airflow discharged from the second air outlet 31a can be directly discharged to the outside of the cooking appliance 1.

[0053] The cooking utensil 1 of the present application is provided with an air guide member 20 to guide the hot and humid air flow to flow only along the extension direction of the first air guide channel 22a, thereby preventing the hot and humid air flow from contacting the cold air flow and condensing into water droplets, thereby reducing the structure for collecting condensed water.
