Description

Technical Field

[0001] The present invention belongs to the technical field of household electrical appliances, and in particular, relates to a cooking box and an electrical appliance. Background Art

[0002] The cooking utensils in the prior art often leave a large amount of water vapor in the cooking cavity after cooking the food, which easily leads to water accumulation in the cooking cavity, and then causes bacteria to grow in the cooking cavity, or causes a large amount of oil smoke to appear when the food is baked in the cooking cavity next time. The traditional exhaust fan cannot prevent the outside gas from entering the cooking cavity when the exhaust fan stops running. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, a first object of the present invention is to provide a cooking box.

[0005] The second objective of the present invention is to provide an electrical device.

[0006] To achieve at least one of the above purposes, according to a first aspect of the present invention, a cooking box is proposed, comprising: a main body, comprising a cooking cavity; a vent, provided in the main body, the vent being connected to the cooking cavity; a ventilation device, provided in the main body, the ventilation device comprising an air inlet passage connected to the vent; the ventilation device comprising: a switch element, movably provided in the air inlet passage, the switch element being used to open or close the air inlet passage, the switch element opening the air inlet passage when the ventilation device is running, and closing the air inlet passage when the ventilation device stops running.

[0007] The cooking box proposed in the present application can be used for an electrical device, the cooking box includes a body, the body includes a cooking cavity for accommodating food, and the electrical device can bake the food. It is understandable that after the electrical device finishes cooking the food, there is often too much steam left in the cooking cavity, which leads to excessive humidity in the cooking cavity and easy accumulation of water. On the one hand, it is easy to cause bacteria to grow in the cooking cavity. On the other hand, when the electrical device bakes the food, too much oil smoke will be formed, resulting in poor baking effect. In order to speed up the discharge speed of the steam in the cooking cavity, the present application sets a vent and a ventilation device on the body. Specifically, the vent is provided on the body, the vent is connected to the cooking cavity, and the steam in the cooking cavity can be discharged to the outside through the vent. The ventilation device is provided on the body, the ventilation device includes an air inlet channel, the air inlet channel is connected to the vent, and the ventilation device can discharge fresh air from the outside into the cooking cavity through the air inlet channel and the vent. When the ventilation device is running, the user can open the door of the cooking box. The fresh air discharged into the cooking cavity by the ventilation device will squeeze the original gas in the cooking cavity, thereby speeding up the discharge of the gas with high humidity in the cooking cavity, reducing the humidity in the cooking cavity, avoiding the formation of water accumulation in the cooking cavity, and keeping the cooking cavity dry.

[0008] Furthermore, the structure of the ventilation device is defined. The ventilation device includes a switch component, which is movably disposed in the air inlet passage. The air inlet passage can be opened or closed by moving the switch component between different positions. It is understandable that when the ventilation device is in operation and fresh air needs to be discharged into the cooking cavity, the switch component needs to be opened so that the outside gas can be smoothly discharged into the cooking cavity. When the ventilation device stops operating and the electrical device is cooking food, if the air inlet passage remains open, it is easy for low-temperature gas from the outside to enter the cooking cavity, reducing the heating rate of the cooking cavity, and thus causing the electrical device to have a poor cooking effect on the food. In order to avoid this problem, the switch component is configured in the present application to be able to close the air inlet passage when the ventilation device stops operating. In this way, low-temperature gas from the outside can be prevented from entering the cooking cavity, so that the electrical device can cook the food normally.

[0009] By arranging a vent hole on the main body and arranging a ventilation device connected to the vent hole in the cooking box, fresh air from the outside can be discharged into the cooking cavity through the ventilation device, so as to accelerate the discharge speed of steam in the cooking cavity, reduce the humidity in the cooking cavity, keep the cooking cavity dry, and avoid water accumulation in the cooking cavity. In this way, on the one hand, it can prevent bacteria from breeding in the cooking cavity, and on the other hand, it can prevent the electrical device from generating a large amount of oil smoke when baking food, thereby improving the cooking effect of the electrical device on food. By arranging a switch in the air inlet channel of the ventilation device, and enabling the switch to open the air inlet channel when the ventilation device is running, and enabling the switch to close the air inlet channel when the ventilation device stops running, it can prevent low-temperature gas from entering the cooking cavity through the air inlet channel when the electrical device is cooking food, so that the cooking cavity can maintain a high temperature state, and the electrical device can cook food normally.

[0010] The cooking box according to the present invention may also have the following distinguishing technical features:

[0011] In the above technical solution, further, the ventilation device also includes: a mounting frame; a fan assembly, which is arranged on the mounting frame; a mounting pipe, which is connected to the mounting frame, one end of the mounting pipe is connected to the air outlet of the fan, and the other end of the mounting pipe can be connected to the vent, and the switch is located in the mounting pipe.

[0012] In this technical solution, the structure of the ventilation device is defined. The ventilation device includes a mounting frame, a fan assembly and a mounting pipe. The fan assembly is arranged on the mounting frame, and the fan assembly is used to form an airflow blown into the cooking cavity. The mounting pipe is connected to the mounting frame, one end of the mounting pipe is connected to the air outlet of the fan assembly, and the other end can be connected to the vent. The mounting pipe is a part of the air intake passage. When the fan assembly is running, the fan assembly forms an inlet airflow, which is discharged from the air outlet of the fan assembly into the mounting pipe, flows along the air intake passage to the vent, and is discharged into the cooking cavity from the vent.

[0013] Furthermore, in order to open and close the air inlet passage, a switch member is disposed in the mounting tube to fix the switch member. The switch member can move relative to the mounting tube to open or close the air inlet passage. Specifically, when the fan assembly is running, the switch member opens the air inlet passage, and the air inlet airflow formed by the fan assembly flows through the mounting tube and flows into the cooking cavity along the air inlet passage. When the fan assembly stops running, the switch member moves relative to the mounting tube, and the switch member closes the air inlet passage. In this way, low-temperature gas from the outside can be prevented from flowing into the cooking cavity through the air inlet passage, so as to ensure that the electrical device can cook the food normally.

[0014] By arranging a mounting tube in the ventilation device and arranging the switch component in the mounting tube, the switch component can be fixed by the mounting tube. Moreover, the mounting tube can be opened and closed by the switch component to realize the opening and closing of the air inlet passage. On the one hand, when the cooking cavity needs to be dehumidified, fresh air from the outside can flow into the cooking cavity. On the other hand, when the food needs to be cooked, the air inlet passage can be closed to prevent the outside low-temperature gas from flowing into the cooking cavity, so as to ensure that the electrical device can cook the food normally.

[0015] In the above technical solution, further, the switch member includes: a rotating shaft connected to the inner wall of the mounting tube; at least one blade rotatably connected to the rotating shaft, and the blade can rotate between its respective first position and second position; when the fan assembly is running, the blade moves to the first position to open the air intake passage, and when the fan assembly stops running, the blade moves to the second position to close the air intake passage.

[0016] In this technical solution, the structure of the switch member is defined. The switch member includes a rotating shaft and at least one blade, wherein the rotating shaft is fixedly connected to the inner wall of the mounting tube, and the blade is rotatably connected to the rotating shaft. Specifically, the blade can be one or more. When there is one blade, the blade is located on one side of the rotating shaft, and when there are more than one blade, the blades are respectively located on both sides of the rotating shaft.

[0017] Furthermore, any blade can rotate between its respective first position and second position. Specifically, when the fan assembly is running, the air intake airflow formed by the fan assembly blows toward the blade, and the wind pressure of the air intake airflow acting on the blade can overcome the gravity of the blade, thereby pushing the blade to rotate in the direction away from the fan assembly until the blade rotates to the first position. When the blade is in the first position, the blade opens the air intake passage, and the air intake airflow flows into the cooking cavity along the air intake passage. When the fan assembly stops running, the air intake airflow disappears, and at this time, the blade rotates in the direction toward the fan assembly under the action of its own gravity until the blade rotates to the second position, and the blade closes the air intake passage, and the low-temperature gas from the outside cannot flow into the cooking cavity through the air intake passage. In this way, the opening and closing of the air intake passage by the switch member can be realized.

[0018] By arranging blades that can rotate around the rotating shaft in the switch component, the air flow formed by the fan assembly can blow the blades to rotate around the rotating shaft within a certain angle range, so that when the fan assembly is running, the blades are blown to a first position to open the air inlet passage, and when the fan assembly stops running, the blades are rotated to a second position under the action of their own gravity to close the air inlet passage.

[0019] In the above technical solution, further, the ventilation device also includes: a stopper, located on the side of the blade facing the fan assembly, the stopper is protrudingly provided on the inner wall of the mounting tube, and when the blade is located at the second position, the blade overlaps the stopper.

[0020] In this technical solution, the structure of the ventilation device is further limited, and a stopper is provided in the ventilation device in order to limit the position of the blade. Specifically, the stopper is located on the side of the blade facing the fan assembly, the stopper is connected to the inner wall of the mounting tube, and the stopper protrudes from the inner wall of the mounting tube. When the blade is in the second position, the edge of the blade overlaps the side of the stopper away from the fan assembly, thereby limiting the position of the blade by the stopper, so that the blade can be kept in the second position.

[0021] The process of the switch component opening and closing the air inlet passage is as follows: when the fan assembly starts to operate, the fan assembly forms an air inlet airflow blowing toward the switch component, and the blades in the switch component rotate in a direction away from the fan assembly under the action of the air inlet airflow, and the blades separate from the stopper, and the air inlet airflow can flow into the air inlet passage through the opening between the blades and the stopper, and be discharged into the cooking cavity. When the fan assembly stops operating, the blades rotate in a direction toward the fan assembly under the action of their own gravity. Since the stopper is provided on the side of the blades facing the fan assembly, when the blades rotate to the second position, the blades overlap the stopper, and the stopper serves to limit the position of the blades. In addition, since the blades fit the stopper, there is no gap between the blades and the stopper, and the low-temperature gas from the outside cannot flow into the air inlet passage, so that the switch component has the technical effect of closing the air inlet passage.

[0022] By arranging a stopper in the ventilation device, on the one hand, the blades can be limited by the stopper so that the blades can be maintained in the second position. On the other hand, the blades fit the stopper to close the air inlet channel, thereby preventing external gas from flowing into the cooking chamber.

[0023] In the above technical solution, further, the ventilation device also includes: a limit plate, connected to the inner wall of the mounting tube, the limit plate is located on the side of the blade facing the fan assembly; any blade is provided with a limit member, when the blade rotates to the first position, the limit member and the limit plate are abutted against each other to allow the blade to rotate within a preset angle range.

[0024] In this technical solution, the structure of the ventilation device is further limited. In order to limit the blades, a limit plate is provided in the ventilation device, and a limit piece adapted to the limit plate is provided on the blade. Specifically, the limit plate is connected to the inner wall of the mounting tube, and the limit plate is located on the side of the blade facing the fan assembly. Any blade is provided with a limit piece, and the limit piece is arranged adjacent to the rotating shaft. In the process of the blade moving toward the first position under the action of the incoming air flow, the limit piece moves toward the limit plate until the limit piece abuts against the limit plate, and the blade moves to the first position. At this time, since the limit plate limits the limit piece, the blade cannot continue to rotate, thereby achieving the technical effect of rotating the blade within a preset angle range.

[0025] Understandably, if the blades rotate to an angle perpendicular to the horizontal plane, the blades will not be able to fall back to the second position under the action of gravity, or if there are multiple blades, if the blades rotate at too large an angle, a blade may flip over to the top of another blade, causing the blade to be unable to fall back to the original second position. The above phenomena will cause the air intake channel to be unable to close. In order to avoid the above problems, the present application provides a limit plate and a limit member adapted to the limit plate in the ventilation device, and the limit plate is used to limit the limit member, thereby limiting the rotation angle range of the blades and avoiding the phenomenon that the blades cannot close the air intake channel.

[0026] In a possible technical solution, there are multiple limiting members on any blade.

[0027] In the above technical solution, further, the preset angle range is 0° to 70°.

[0028] In this technical solution, the preset angle range is limited, specifically, the preset angle range is 0° to 70°, so that even if the blades rotate to 70°, the blades can still fall back to the second position under the action of gravity to close the air intake passage.

[0029] By limiting the preset angle range to 0° to 70°, the problem that the blade cannot fall back to the original second position due to excessive rotation angle can be avoided, so that the switch element can normally open or close the air intake channel.

[0030] In the above technical solution, further, when the number of the blade is one, the rotating shaft is in contact with the inner wall of the mounting tube, and the blade is located on the side of the rotating shaft away from the inner wall of the mounting tube.

[0031] In this technical solution, when there is only one blade, the rotating shaft fits the side wall of the mounting tube, there is no gap between the rotating shaft and the side wall of the mounting tube, and the blade is rotatably connected to one side of the rotating shaft, specifically, the blade is located on the side of the rotating shaft away from the inner wall of the mounting tube to which the rotating shaft is connected. In this way, the blade can completely cover the cross section of the mounting tube to play the role of closing the air intake pipeline.

[0032] Furthermore, the stopper is arranged opposite to the rotating shaft, and the stopper is connected to the tube wall of the mounting tube on the side opposite to the rotating shaft. One end of the blade is rotatably connected to the rotating shaft, and the other end can overlap the stopper.

[0033] In the above technical solution, further, in the case where there are multiple blades, both ends of the rotating shaft are respectively connected to the inner wall of the mounting tube, and the multiple blades are respectively located on both sides of the rotating shaft.

[0034] In this technical solution, the number of blades can also be multiple. In the case of multiple blades, the two ends of the rotating shaft are respectively connected to the tube wall of the mounting tube, the rotating shaft is located in the middle area of ​​the mounting tube, and the multiple blades are respectively located on both sides of the rotating shaft. When the fan assembly is running, the incoming airflow acts on the blades, and the blades rotate toward their respective first positions. At this time, the blades on both sides of the rotating shaft move toward each other. When the fan assembly stops running, the blades rotate toward their respective second positions under the action of their own gravity. At this time, the blades on both sides of the rotating shaft move away from each other.

[0035] Further, the number of the stoppers can be two, and the two stoppers are respectively connected to the tube walls of the mounting tube located on both sides of the rotating shaft. One end of any blade is connected to the rotating shaft, and the other end can overlap the corresponding stopper.

[0036] In the above technical solution, further, the cooking box also includes: an air intake pipe, both ends of which are respectively connected to the main body and the mounting pipe, and the mounting pipe and the air intake pipe together constitute an air intake channel.

[0037] In this technical solution, the structure of the cooking box is further defined. In order to facilitate the introduction of the air intake airflow formed by the fan assembly into the cooking cavity, an air intake pipe is also provided in the cooking box. Specifically, one end of the air intake pipe is connected to the mounting pipe, and the other end is connected to the body. The air inlet of the air intake pipe is connected to the end of the mounting pipe away from the fan assembly, and the air outlet of the air intake pipe is connected to the vent provided on the body, so that the mounting pipe and the air intake pipe together constitute an air intake channel. When the fan assembly is running, the air intake airflow formed by the fan assembly flows through the switch member provided on the air intake pipe, and the air intake airflow flows along the mounting pipe and the air intake pipe to the vent, and flows into the cooking cavity through the vent.

[0038] In a possible technical solution, the air inlet pipe is constructed with an arc-shaped bending structure, so that the installation space of the air inlet pipe and the ventilation device can be saved, the overall structure of the cooking box is more compact, and it is conducive to the miniaturization design of the product.

[0039] By arranging an air intake pipe in the cooking box, the two ends of the air intake pipe are respectively connected to the vent hole arranged in the main body and the installation pipe in the ventilation device, so that the air intake airflow formed by the fan assembly can be introduced into the cooking cavity through the air intake pipe.

[0040] In the above technical solution, further, the ventilation device also includes: multiple mounting parts, which are respectively arranged at both ends of the air intake pipe and one end of the mounting pipe facing the air intake pipe, and the mounting parts are used to connect the air intake pipe with the main body and the mounting pipe.

[0041] In this technical solution, the structure of the ventilation device is further defined. In order to facilitate the connection of the air intake pipe with the body and the mounting pipe, a plurality of mounting parts are also provided on the air intake pipe. Specifically, at least some of the plurality of mounting parts are respectively provided at both ends of the air intake pipe, and at least one of the plurality of mounting parts is provided at one end of the mounting pipe facing the air intake pipe. In this way, the air intake pipe and the mounting pipe can be connected to each other through two matching mounting parts, and the air intake pipe can also be connected to the body through the mounting part, thereby realizing the connection of the body, the air intake pipe and the mounting pipe in sequence.

[0042] Furthermore, a seal is provided in the cooking box body. Specifically, there are multiple seals, at least one of which is arranged between the wall surface of the main body and a mounting piece located at one end of the air intake pipe toward the main body, and at least one of which is arranged between a mounting piece at one end of the air intake pipe toward the mounting pipe and a mounting piece arranged on the mounting pipe, so as to improve the airtightness of the air intake passage, reduce the leakage of the intake air flow, and improve the ventilation efficiency of the ventilation device.

[0043] In a possible technical solution, the sealing element is configured as a sealing pad.

[0044] By arranging mounting parts at both ends of the air intake pipe and at one end of the mounting pipe facing the air intake pipe, the air intake pipe can be connected to the main body and the air intake pipe can be connected to the mounting pipe through the mounting parts, thereby realizing the sequential connection of the main body, the air intake pipe and the mounting pipe.

[0045] In the above technical solution, further, the mounting member is constructed as a flange.

[0046] In this technical solution, the structure of the mounting member is defined, specifically, the mounting member is configured as a flange. It is understandable that the flange structure has a simple processing method and high connection stability. By respectively arranging flanges at both ends of the air intake pipe and at one end of the mounting pipe facing the air intake pipe, a reliable connection between the air intake pipe and the body and between the air intake pipe and the mounting pipe can be achieved.

[0047] In the above technical solution, further, the cooking box body also includes: a plurality of connecting members, and the plurality of connecting members are passed through any two adjacent mounting members to connect any two adjacent mounting members.

[0048] In this technical solution, a plurality of connectors are further provided in the cooking box body, and the connectors are used to connect two adjacent mounting members to each other, or to connect the mounting members to the main body. At least some of the plurality of connectors are provided through any two adjacent mounting members to connect any two adjacent mounting members, and at least some of the plurality of connectors pass through the mounting member provided at one end of the air inlet pipe facing the main body and are connected to the main body to connect the air inlet pipe to the main body.

[0049] In a possible technical solution, the connecting element is configured as a screw or a stud.

[0050] By arranging a plurality of connecting members in the cooking box, any two adjacent mounting members can be connected through the connecting members, and the mounting members can be connected to the main body, so as to realize the connection between the air inlet pipe, the mounting pipe and the main body.

[0051] In the above technical solution, further, the mounting frame includes: a mounting plate connected to the mounting pipe, the mounting plate extends in a direction away from the air inlet pipe, and the fan assembly is connected to the mounting plate.

[0052] In this technical solution, in order to facilitate the installation and fixation of the fan assembly, a mounting plate for mounting the fan assembly is provided in the mounting frame. Specifically, the mounting plate is connected to the end of the mounting tube and extends in a direction away from the mounting tube. The fan assembly is connected to the mounting plate to achieve the installation and fixation of the fan assembly. One of the mounting plate and the fan assembly is provided with a threaded hole, and the other is provided with a through hole corresponding to the threaded hole. The fan assembly and the mounting plate can be connected by screws.

[0053] In the above technical solution, further, the cooking box body also includes: a door body, which is used to open or close the cooking cavity, and the ventilation holes are arranged on the side walls of the main body and the door body that are arranged opposite to each other.

Specifically, the door body is rotatably connected to the main body, so that the door body can rotate relative to the main body within a certain angle range, thereby realizing the opening and closing of the cooking cavity.

[0055] Furthermore, a through hole is provided on the side wall opposite to the main body and the door body, so that the air intake airflow formed by the fan assembly can flow into the cooking cavity through the area where the side wall opposite to the door body is located, so that the external gas can more evenly squeeze the steam in the cooking cavity to the outside through the opening between the door body and the main body, thereby keeping the humidity in each area of ​​the cooking cavity balanced.

[0056] By arranging the vent holes on the side walls opposite to the main body and the door body, the external gas can more evenly squeeze the steam in the cooking cavity to the outside through the opening between the door body and the main body, so that the humidity in each area of ​​the cooking cavity is kept balanced.

DETAILED DESCRIPTION

[0090] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0091] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0092] Refer to the following Figures 1 to 26The cooking box 100 and the electrical device provided according to some embodiments of the present invention are described.

[0093] In one embodiment according to the present application, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the first aspect of the present invention proposes a cooking box 100, comprising: a main body 110, including a cooking cavity 112; a vent 111, provided on the main body 110, the vent 111 is connected to the cooking cavity 112; a ventilation device 120, provided on the main body 110, the ventilation device 120 includes an air inlet channel 127 connected to the vent 111; the ventilation device 120 includes: a switch member 130, movably provided in the air inlet channel 127, the switch member 130 is used to open or close the air inlet channel 127, when the ventilation device 120 is running, the switch member 130 opens the air inlet channel 127, when the ventilation device 120 stops running, the switch member 130 closes the air inlet channel 127.

[0094] The cooking box 100 proposed in the present application can be used for an electrical device. The cooking box 100 includes a body 110. The body 110 includes a cooking cavity 112 for accommodating food. The electrical device can bake the food. It is understandable that after the electrical device finishes cooking the food, there is often too much steam left in the cooking cavity 112, which leads to excessive humidity in the cooking cavity 112 and easy accumulation of water. On the one hand, it is easy to cause bacteria to grow in the cooking cavity 112. On the other hand, when the electrical device bakes the food, too much oil smoke will be generated, resulting in poor baking effect. In order to speed up the discharge speed of the steam in the cooking cavity 112, the present application sets a vent 111 and a ventilation device 120 on the body 110. Specifically, the vent 111 is set on the body 110, and the vent 111 is connected to the cooking cavity 112. The steam in the cooking cavity 112 can be discharged to the outside through the vent 111. The ventilation device 120 is disposed on the body 110 and includes an air inlet passage 127, which is connected to the vent hole 111. The ventilation device 120 can discharge fresh air from the outside into the cooking cavity 112 through the air inlet passage 127 and the vent hole 111. Figure 7 and Figure 8 As shown, when the ventilation device 120 is running, the user can open the door 160 of the cooking box 100, and the fresh air discharged into the cooking cavity 112 by the ventilation device 120 squeezes the original gas in the cooking cavity 112, thereby accelerating the discharge speed of the gas with high humidity in the cooking cavity 112, reducing the humidity in the cooking cavity 112, avoiding the formation of water accumulation in the cooking cavity 112, and keeping the cooking cavity 112 dry.

[0095] Furthermore, the structure of the ventilation device 120 is defined. The ventilation device 120 includes a switch member 130, and the switch member 130 is movably disposed in the air inlet passage 127. The air inlet passage 127 can be opened or closed by moving the switch member 130 between different positions. It is understandable that when the ventilation device 120 is running and fresh air needs to be discharged into the cooking cavity 112, the switch member 130 needs to be opened so that the outside gas can be smoothly discharged into the cooking cavity 112. When the ventilation device 120 stops running and the electrical device is cooking the food, if the air inlet passage 127 is still kept open, it is easy for low-temperature outside gas to enter the cooking cavity 112, reducing the heating rate of the cooking cavity 112, and further resulting in poor cooking effect of the electrical device on the food. In order to avoid this problem, if Figure 5 and Figure 6 As shown, in the present application, the switch element 130 is configured to close the air inlet passage 127 when the ventilation device 120 stops running, thereby preventing the external low-temperature gas from entering the cooking cavity 112, so that the electrical device can cook the food normally.

[0096] By providing the vent hole 111 on the main body 110 and providing the ventilation device 120 in communication with the vent hole 111 in the cooking box 100, fresh air from the outside can be discharged into the cooking cavity 112 through the ventilation device 120, so as to accelerate the discharge speed of steam in the cooking cavity 112, reduce the humidity in the cooking cavity 112, keep the cooking cavity 112 in a dry state, and avoid water accumulation in the cooking cavity 112. In this way, on the one hand, it is possible to prevent bacteria from growing in the cooking cavity 112, and on the other hand, it is possible to prevent the electrical device from generating a large amount of oil smoke when baking food, thereby improving the cooking effect of the electrical device on food. By arranging a switch component 130 in the air inlet passage 127 of the ventilation device 120, and enabling the switch component 130 to open the air inlet passage 127 when the ventilation device 120 is running, and enabling the switch component 130 to close the air inlet passage 127 when the ventilation device 120 stops running, it is possible to prevent low-temperature gas from the outside from entering the cooking cavity 112 through the air inlet passage 127 when the electrical device is cooking food, so that the cooking cavity 112 can maintain a high temperature state, allowing the electrical device to cook food normally.

[0097] In one embodiment according to the present application, Figure 3 , Figure 4 , Fig.17 , Fig.18 , Fig.19 and Fig. 20As shown, the ventilation device 120 also includes: a mounting frame 121; a fan assembly 122, which is arranged on the mounting frame 121; a mounting tube 123, which is connected to the mounting frame 121, one end of the mounting tube 123 is connected to the air outlet of the fan, and the other end of the mounting tube 123 can be connected to the vent 111, and the switch member 130 is located in the mounting tube 123.

[0098] In this embodiment, the structure of the ventilation device 120 is defined. The ventilation device 120 includes a mounting frame 121, a fan assembly 122 and a mounting pipe 123. The fan assembly 122 is arranged on the mounting frame 121. The fan assembly 122 is used to form an airflow blown into the cooking cavity 112. The mounting pipe 123 is connected to the mounting frame 121. One end of the mounting pipe 123 is connected to the air outlet of the fan assembly 122, and the other end can be connected to the vent 111. The mounting pipe 123 is a part of the air inlet channel 127. When the fan assembly 122 is running, the fan assembly 122 forms an inlet airflow, which is discharged from the air outlet of the fan assembly 122 into the mounting pipe 123, flows along the air inlet channel 127 to the vent 111, and is discharged into the cooking cavity 112 from the vent 111.

[0099] Furthermore, if Fig.21 , Fig. 22 , Fig.23 and Fig.24 As shown, in order to open and close the air inlet passage 127, the switch member 130 is arranged in the mounting tube 123 to fix the switch member 130. The switch member 130 can move relative to the mounting tube 123 to open or close the air inlet passage 127. Specifically, when the fan assembly 122 is running, the switch member 130 opens the air inlet passage 127, and the air inlet air flow formed by the fan assembly 122 flows through the mounting tube 123 and flows into the cooking cavity 112 along the air inlet passage 127. When the fan assembly 122 stops running, the switch member 130 moves relative to the mounting tube 123, and the switch member 130 closes the air inlet passage 127. In this way, low-temperature gas from the outside can be prevented from flowing into the cooking cavity 112 through the air inlet passage 127, so as to ensure that the electrical device can cook the food normally.

[0100] By arranging the mounting tube 123 in the ventilation device 120 and arranging the switch member 130 in the mounting tube 123, the switch member 130 can be fixed by the mounting tube 123. Moreover, the mounting tube 123 can be opened and closed by the switch member 130, so as to realize the opening and closing of the air inlet passage 127 by the switch member 130. On the one hand, when the cooking cavity 112 needs to be dehumidified, fresh air from the outside can flow into the cooking cavity 112. On the other hand, when the food needs to be cooked, the air inlet passage 127 can be closed so that the low-temperature gas from the outside cannot flow into the cooking cavity, so as to ensure that the electrical device can cook the food normally.

[0101] In one embodiment according to the present application, Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 , Fig.14 , Fig.15 and Fig.16 As shown, the switch member 130 includes: a rotating shaft 131, which is connected to the inner wall of the mounting tube 123; at least one blade 132, which is rotatably connected to the rotating shaft 131, and the blade 132 can rotate between its respective first position and second position; when the fan assembly 122 is running, the blade 132 moves to the first position to open the air intake passage 127, and when the fan assembly 122 stops running, the blade 132 moves to the second position to close the air intake passage 127.

[0102] In this embodiment, the structure of the switch member 130 is defined. The switch member 130 includes a rotating shaft 131 and at least one blade 132, wherein the rotating shaft 131 is fixedly connected to the inner wall of the mounting tube 123, and the blade 132 is rotatably connected to the rotating shaft 131. Specifically, the blade 132 may be one or more. When there is one blade 132, the blade 132 is located on one side of the rotating shaft 131, and when there are more than one blade 132, the multiple blades 132 are respectively located on both sides of the rotating shaft 131.

[0103] Further, any blade 132 can rotate between its first position and its second position. Figure 7 and Fig.25 As shown, when the fan assembly 122 is running, the airflow formed by the fan assembly 122 blows toward the blade 132, and the wind pressure of the airflow acting on the blade 132 can overcome the gravity of the blade 132, thereby pushing the blade 132 to rotate in a direction away from the fan assembly 122 until the blade 132 rotates to the first position. When the blade 132 is in the first position, the blade 132 opens the air inlet channel 127, and the airflow flows into the cooking cavity 112 along the air inlet channel 127. Figure 5 , Fig.21 and Fig. 22 As shown, when the fan assembly 122 stops running, the airflow disappears, and the blade 132 rotates in the direction toward the fan assembly 122 under the action of its own gravity until the blade 132 rotates to the second position, and the blade 132 closes the air inlet passage 127, so that the low-temperature gas from the outside cannot flow into the cooking cavity 112 through the air inlet passage 127. In this way, the switch member 130 can open and close the air inlet passage 127.

[0104] By arranging blades 132 capable of rotating around the rotating shaft 131 in the switch member 130, the airflow formed by the fan assembly 122 can blow the blades 132 to rotate around the rotating shaft 131 within a certain angle range, so as to achieve the goal of blowing the blades 132 to rotate to the first position when the fan assembly 122 is running to open the air inlet passage 127, and to make the blades 132 rotate to the second position under the action of their own gravity to close the air inlet passage 127 when the fan assembly 122 stops running.

[0105] In one embodiment according to the present application, Fig.11 , Fig.15 , Fig.23 and Fig.24 As shown, the ventilation device 120 also includes: a stopper 124, which is located on the side of the blade 132 facing the fan assembly 122, and the stopper 124 is protrudingly provided on the inner wall of the mounting tube 123. When the blade 132 is located at the second position, the blade 132 overlaps the stopper 124.

[0106] In this embodiment, the structure of the ventilation device 120 is further defined, and a stopper 124 is further provided in the ventilation device 120 in order to limit the position of the blade 132. Specifically, the stopper 124 is located on the side of the blade 132 facing the fan assembly 122, the stopper 124 is connected to the inner wall of the mounting tube 123, and the stopper 124 protrudes from the inner wall of the mounting tube 123. When the blade 132 is located at the second position, the edge of the blade 132 overlaps the side of the stopper 124 away from the fan assembly 122, thereby limiting the position of the blade 132 by the stopper 124, so that the blade 132 can be maintained at the second position.

[0107] The process of the switch member 130 opening and closing the air inlet passage is as follows: when the fan assembly 122 starts to operate, the fan assembly 122 forms an air inlet airflow blowing toward the switch member 130, and the blade 132 in the switch member 130 rotates in a direction away from the fan assembly 122 under the action of the air inlet airflow, and the blade 132 separates from the stopper 124, and the air inlet airflow can flow into the air inlet passage through the opening between the blade 132 and the stopper 124, and is discharged into the cooking cavity 112. When the fan assembly 122 stops operating, the blade 132 rotates in a direction toward the fan assembly 122 under the action of its own gravity. Since the stopper 124 is provided on the side of the blade 132 facing the fan assembly 122, when the blade 132 rotates to the second position, the blade 132 overlaps the stopper 124, and the stopper 124 plays a role in limiting the position of the blade 132. Furthermore, since the blade 132 fits closely with the stopper 124 and there is no gap between the blade 132 and the stopper 124 , low-temperature gas from the outside cannot flow into the air inlet passage, so that the switch element 130 has the technical effect of closing the air inlet passage.

[0108] By setting a stopper 124 in the ventilation device 120, on the one hand, the blade 132 can be limited by the stopper 124 so that the blade 132 can be maintained in the second position. On the other hand, the blade 132 fits against the stopper 124 to close the air inlet channel, thereby preventing external gas from flowing into the cooking chamber 112.

[0109] In one embodiment according to the present application, Fig.24 and Fig.26 As shown, the ventilation device 120 also includes: a limit plate 125, which is connected to the inner wall of the mounting tube 123, and the limit plate 125 is located on the side of the blade 132 facing the fan assembly 122; any blade 132 is provided with a limit member 133, and when the blade 132 rotates to the first position, the limit member 133 abuts against the limit plate 125 to allow the blade 132 to rotate within a preset angle range.

[0110] In this embodiment, the structure of the ventilation device 120 is further defined. In order to limit the blade 132, a limit plate 125 is further provided in the ventilation device 120, and a limit member 133 adapted to the limit plate 125 is provided on the blade 132. Specifically, the limit plate 125 is connected to the inner wall of the mounting tube 123, and the limit plate 125 is located on the side of the blade 132 facing the fan assembly 122. Any blade 132 is provided with a limit member 133, and the limit member 133 is arranged adjacent to the rotating shaft 131. In the process of the blade 132 moving toward the first position under the action of the incoming air flow, the limit member 133 moves toward the limit plate 125 until the limit member 133 abuts against the limit plate 125, and the blade 132 moves to the first position. At this time, since the limit plate 125 limits the limit member 133, the blade 132 cannot continue to rotate, thereby achieving the technical effect of rotating the blade 132 within a preset angle range.

[0111] Understandably, if the blade 132 rotates to an angle perpendicular to the horizontal plane, the blade 132 will not be able to fall back to the second position under the action of gravity, or if there are multiple blades 132, if the blade 132 rotates at too large an angle, a blade 132 may flip over to the top of another blade 132, causing the blade 132 to be unable to fall back to the original second position. The above phenomenon will cause the air intake passage 127 to be unable to close. In order to avoid the above problems, the present application sets a limit plate 125 and a limit member 133 adapted to the limit plate 125 in the ventilation device 120, and the limit member 133 is limited by the limit plate 125, thereby limiting the rotation angle range of the blade 132, and avoiding the phenomenon that the blade 132 cannot close the air intake passage.

[0112] In a possible embodiment, there are multiple limiting members 133 on any blade 132 .

[0113] In one embodiment of the present application, the preset angle range is 0° to 70°.

[0114] In this embodiment, the preset angle range is limited, specifically, the preset angle range is 0° to 70°, so that even if the blade 132 rotates to 70°, the blade 132 can still fall back to the second position under the action of gravity to close the air intake channel 127.

[0115] By limiting the preset angle range to 0° to 70°, the problem that the blade 132 cannot fall back to the original second position due to excessive rotation angle can be avoided, so that the switch member 130 can normally open or close the air intake channel 127.

[0116] In one embodiment of the present application, when there is only one blade 132 , the shaft 131 is in contact with the inner wall of the mounting tube 123 , and the blade 132 is located on a side of the shaft 131 that is away from the inner wall of the mounting tube 123 .

[0117] In this embodiment, when there is only one blade 132, the rotating shaft 131 is fitted with the side wall of the mounting tube 123, there is no gap between the rotating shaft 131 and the side wall of the mounting tube 123, and the blade 132 is rotatably connected to one side of the rotating shaft 131. Specifically, the blade 132 is located on the side of the rotating shaft 131 away from the inner wall of the mounting tube 123 connected to the rotating shaft 131. In this way, the blade 132 can completely cover the cross section of the mounting tube 123 to play the role of closing the air intake pipe 140.

[0118] Furthermore, the stopper 124 is disposed opposite to the rotating shaft 131 and connected to the tube wall of the mounting tube 123 on the side opposite to the rotating shaft 131. One end of the blade 132 is rotatably connected to the rotating shaft 131 and the other end can overlap the stopper 124.

[0119] In one embodiment according to the present application, Fig.21 and Fig.23 As shown, when there are multiple blades 132 , both ends of the rotating shaft 131 are respectively connected to the inner wall of the mounting tube 123 , and the multiple blades 132 are respectively located on both sides of the rotating shaft 131 .

[0120] In this embodiment, the number of blades 132 may also be multiple. When the number of blades 132 is multiple, both ends of the rotating shaft 131 are respectively connected to the tube wall of the mounting tube 123, the rotating shaft 131 is located in the middle area of ​​the mounting tube 123, and the multiple blades 132 are respectively located on both sides of the rotating shaft 131. When the fan assembly 122 is running, the incoming airflow acts on the blades 132, and the blades 132 rotate toward their respective first positions. At this time, the blades 132 located on both sides of the rotating shaft 131 move toward each other. When the fan assembly 122 stops running, the blades 132 rotate toward their respective second positions under the action of their own gravity. At this time, the blades 132 located on both sides of the rotating shaft 131 move away from each other.

[0121] Furthermore, the number of the stoppers 124 can be two, and the two stoppers 124 are respectively connected to the tube walls of the mounting tube 123 located on both sides of the rotating shaft 131. One end of any blade 132 is connected to the rotating shaft 131, and the other end can overlap the corresponding stopper 124.

[0122] In one embodiment according to the present application, Figure 3 , Figure 4 and Fig. 20 As shown, the cooking box 100 further includes: an air intake pipe 140 , both ends of which are respectively connected to the body 110 and the mounting pipe 123 , and the mounting pipe 123 and the air intake pipe 140 together form an air intake channel 127 .

[0123] In this embodiment, the structure of the cooking box 100 is further defined. In order to facilitate the introduction of the air intake airflow formed by the fan assembly 122 into the cooking chamber 112, an air intake pipe 140 is further provided in the cooking chamber 100. Specifically, one end of the air intake pipe 140 is connected to the mounting pipe 123, and the other end is connected to the body 110. The air inlet of the air intake pipe 140 is connected to the end of the mounting pipe 123 away from the fan assembly 122, and the air outlet of the air intake pipe 140 is connected to the vent 111 provided in the body 110, so that the mounting pipe 123 and the air intake pipe 140 together form an air intake channel 127. When the fan assembly 122 is running, the air intake airflow formed by the fan assembly 122 flows through the switch member 130 provided on the air intake pipe 140, and the air intake airflow flows along the mounting pipe 123 and the air intake pipe 140 to the vent 111, and flows into the cooking chamber 112 through the vent 111.

[0124] In a possible embodiment, the air inlet pipe 140 is constructed to have an arc-shaped bending structure, so that the installation space of the air inlet pipe 140 and the ventilation device 120 can be saved, making the overall structure of the cooking box 100 more compact, which is conducive to the miniaturized design of the product.

[0125] By setting an air intake pipe 140 in the cooking box 100, the two ends of the air intake pipe 140 are respectively connected to the vent hole 111 provided in the main body 110 and the installation pipe 123 in the ventilation device 120, so that the intake air flow formed by the fan assembly 122 can be introduced into the cooking cavity 112 through the air intake pipe 140.

[0126] In one embodiment according to the present application, Fig. 9 , Fig.11 , Fig.12 , Fig.13 , Fig.15 and Fig.16 As shown, the ventilation device 120 also includes: multiple mounting members 150, which are respectively arranged at both ends of the air intake pipe 140 and one end of the mounting tube 123 facing the air intake pipe 140, and the mounting members 150 are used to connect the air intake pipe 140 with the body 110 and the mounting tube 123.

[0127] In this embodiment, the structure of the ventilation device 120 is further defined.

Specifically, at least some of the plurality of mounting members 150 are respectively provided at both ends of the air intake pipe 140, and at least one of the plurality of mounting members 150 is provided at one end of the mounting pipe 123 facing the air intake pipe 140. In this way, the air intake pipe 140 and the mounting pipe 123 can be connected to each other through two matching mounting members 150, and the air intake pipe 140 can also be connected to the body 110 through the mounting member 150, thereby realizing the sequential connection of the body 110, the air intake pipe 140 and the mounting pipe 123.

[0128] Furthermore, a seal is also provided in the cooking box 100. Specifically, there are multiple seals, at least one of the multiple seals is arranged between the wall of the main body 110 and the mounting piece 150 located at the end of the air inlet pipe 140 facing the main body 110, and at least one of the multiple seals is arranged between the mounting piece 150 at the end of the air inlet pipe 140 facing the mounting pipe 123 and the mounting piece 150 arranged on the mounting pipe 123, so as to improve the airtightness of the air inlet passage 127, reduce the leakage of the intake air flow, and improve the ventilation efficiency of the ventilation device 120.

[0129] In a possible embodiment, the sealing element is configured as a sealing gasket.

[0130] By setting mounting parts 150 at both ends of the air intake pipe 140 and at one end of the mounting tube 123 facing the air intake pipe 140, the air intake pipe 140 can be connected to the main body 110 and the air intake pipe 140 can be connected to the mounting tube 123 through the mounting parts 150, thereby realizing the sequential connection of the main body 110, the air intake pipe 140 and the mounting tube 123.

[0131] In one embodiment according to the present application, Fig. 9 , Fig.11 , Fig.12 , Fig.13 , Fig.15 and Fig.16 As shown, the mounting element 150 is designed as a flange.

[0132] In this embodiment, the structure of the mounting member 150 is defined, specifically, the mounting member 150 is configured as a flange. It can be understood that the flange structure has a simple processing method and high connection stability. By respectively providing flanges at both ends of the air intake pipe 140 and at one end of the mounting pipe 123 facing the air intake pipe 140, reliable connection between the air intake pipe 140 and the body 110 and between the air intake pipe 140 and the mounting pipe 123 can be achieved.

[0133] In one embodiment of the present application, the cooking box 100 further includes: a plurality of connecting members, and the plurality of connecting members are disposed through any two adjacent mounting members 150 to connect any two adjacent mounting members 150 .

[0134] In this embodiment, a plurality of connectors are further provided in the cooking box 100, and the connectors are used to connect two adjacent mounting members 150 to each other, or to connect the mounting member 150 to the body 110. At least some of the plurality of connectors are provided through any two adjacent mounting members 150 to connect any two adjacent mounting members 150, and at least some of the plurality of connectors pass through the mounting member 150 provided at one end of the air inlet pipe 140 facing the body 110 and are connected to the body to connect the air inlet pipe 140 to the body.

The door body 160 is connected to the body 110 and can move between different positions relative to the body 110 to open or close the cooking cavity 112. Specifically, the door body 160 is rotatably connected to the body 110, so that the door body 160 can rotate relative to the body 110 within a certain angle range, thereby realizing the opening and closing of the cooking cavity 112.

[0141] Furthermore, a through hole is provided on the side wall opposite to the main body 110 and the door body 160, so that the air intake airflow formed by the fan assembly 122 can flow into the cooking cavity 112 through the area where the side wall opposite to the door body 160 is located, so that the external gas can more evenly squeeze the steam in the cooking cavity 112 to the outside through the opening between the door body 160 and the main body 110, so that the humidity in each area of ​​the cooking cavity 112 is kept balanced.

[0142] By arranging the vent hole 111 on the side wall opposite to the main body 110 and the door body 160, the external gas can more evenly squeeze the steam in the cooking cavity 112 to the outside through the opening between the door body 160 and the main body 110, so that the humidity in each area of ​​the cooking cavity 112 is kept balanced.
