It combines multiple functions such as a microwave oven, a steamer and an oven, and can realize multiple cooking tasks such as steaming, baking, frying and microwaving in one cooking cavity, allowing users to complete a variety of cooking tasks in one device.

[0004] However, when using these functions to cook, the smell of food often remains in the cooking chamber, and this residual smell may cause odor transfer problems during subsequent cooking processes, affecting the taste of the newly cooked food and the overall cooking experience. Summary of the invention

[0005] In view of the above problems, an embodiment of the present application provides a cooking device for purifying the residual taste of food in the cooking cavity and avoiding the problem of the purification unit not being able to withstand high temperatures, while improving the sealing of the cooking cavity during cooking, thereby improving the taste of food and the user's cooking experience.

[0006] In order to achieve the above objectives, the embodiments of the present application provide the following technical solutions:

When the shielding member closes the window, the sealing component is at least arranged between the shielding member and the outer wall of the cooking cavity to seal the gap between the shielding member and the periphery of the window.

[0012] In the cooking device provided in the embodiment of the present application, a purification unit and a shielding member are movably arranged on the device body, and a window is arranged on the device body. The shielding member can open or close the window. When the shielding member opens the window, the purification unit can move into the cooking cavity or move out of the cooking cavity through the window under the action of force. In this way, when cooking is finished, the purification unit can be moved into the cooking cavity through the window to remove the residual taste of food in the cooking cavity through the purification unit; and when cooking, the purification unit is moved out of the cooking cavity to solve the problem that the purification unit is not resistant to high temperatures, thereby improving the taste of cooked food and the user's cooking experience; in addition, a sealing component is arranged around the window, when the shielding member closes the window, the sealing component seals the gap between the shielding member and the periphery of the window to improve the sealing of the cooking cavity, thereby avoiding affecting the cooking effect due to poor sealing at the window during cooking.

[0097] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0098] Please refer to Figure 1 As shown, an embodiment of the present application provides a cooking device 100, including a device body 110, wherein the device body 110 has a cooking cavity 111, and the cooking cavity 111 is used to accommodate food to be cooked, that is, the food can be cooked in the cooking cavity 111.

[0099] The cooking device 100 includes but is not limited to a microwave oven, a steamer, an oven and other multiple functions, and can realize multiple cooking tasks such as steaming, baking, frying and microwaving in a cooking cavity 111, so that users can complete various cooking tasks in one device.

[0100] However, when using these functions to cook, the smell of food often remains in the cooking cavity 111, and this residual smell may cause odor transfer during the subsequent cooking process, affecting the taste of the newly cooked food and the overall cooking experience.

[0101] In order to remove the smell of food residue in the cooking cavity 111, in some embodiments, a purifier is provided in the cooking cavity 111, and the purifier includes a purification unit 120 and an ionization unit 170. The purification unit 120 is electrically connected to the ionization unit 170. The purification unit 120 includes but is not limited to a negative ion generator or a negative ion carbon brush, that is, when the purification unit 120 is electrically connected to the ionization unit 170, the purification unit 120 can generate, for example, negative ions. The purification unit 120 releases negative ions, and the negative ions combine with the odor ions to remove the odor in the cooking cavity 111. The odor removal method is simple, thereby removing the smell of food residue in the cooking cavity 111, improving the taste of cooked food, and thereby improving the user experience.

[0102] However, the purifier has the problem of not being able to withstand high temperatures. Therefore, placing the purifier in the cooking cavity 111 may cause certain safety hazards, resulting in poor safety and reliability of the cooking device 100.

[0103] Based on the above problems, in the embodiments of this application, please refer to Figure 4 and Figure 5 As shown, a window 112 is provided on the cavity wall of the cooking cavity of the device body 110, connecting the inside and outside of the cooking cavity 111. The purification unit 120 is movably arranged on the device body 110, and the ionization unit 170 is fixedly arranged outside the cooking cavity 111 and fixedly connected to the device body 110. The purification unit 120 is electrically connected to the ionization unit 170. The purification unit 120 can enter the cooking cavity 111 through the window 112, or move out to the outside of the cooking cavity 111 through the window 112.

[0104] When food needs to be cooked, the purification unit 120 can be moved out of the cooking cavity 111 through the window 112 to avoid the problem of damage to the purification unit 120 due to the high temperature in the cooking cavity 111; when cooking is completed, the purification unit 120 can enter the interior of the cooking cavity 111 through the window 112. In this way, the purification unit 120 starts working and can remove the residual taste of food in the cooking cavity 111, thereby improving the taste of food cooked next time.

[0105] In some embodiments, the cooking device 100 also includes a driving mechanism 140, a power output end of the driving mechanism 140 is drivingly connected to the purification unit 120, and the driving mechanism 140 drives the purification unit 120 to move closer to or away from the window 112, so that the purification unit 120 moves through the window 112 into the cooking cavity 111 or moves out of the cooking cavity 111.

[0106] In this way, when cooking is finished, the driving mechanism 140 drives the purification unit 120 to move close to the window 112, so that the purification unit 120 can enter the cooking cavity 111 through the window 112, so as to remove the residual taste of food in the cooking cavity 111 through the purification unit 120; and when food needs to be cooked, the driving mechanism 140 drives the purification unit 120 to move through the window 112 and move out of the cooking cavity 111, so as to solve the problem that the purification unit 120 is not resistant to high temperatures, thereby improving the taste of cooked food and the user's cooking experience.

[0107] It should be noted that the driving mechanism 140 is arranged outside the cooking cavity 111. In this way, the problem that the driving mechanism 140 is not resistant to high temperatures can be avoided. In addition, the volume of the cooking cavity 111 can be increased, thereby improving the user experience.

[0108] Since the window 112 is provided on the wall of the cooking cavity 111, the airtightness of the cooking cavity 111 during operation will be affected. Therefore, in the embodiment of the present application, the cooking device 100 further includes a shielding member 130, which is movably provided on the device body 110 and connected to the driving mechanism 140. The driving mechanism 140 drives the shielding member 130 to move so as to open or close the window 112. That is, when the cooking device 100 is not in cooking operation, the shielding member 130 can be driven to move so that the shielding member 130 opens the window 112 (such as Figure 5 ), and the driving mechanism 140 drives the purification unit 120 to enter the cooking cavity 111 through the window 112 to remove the residual smell of food in the cooking cavity 111; when cooking needs to be started, the purification unit 120 moves out of the cooking cavity 111, and the shielding member 130 moves to the window 112 to close the window 112 (as shown in FIG. Figure 2 As shown in ), the cooking cavity 111 forms a closed cooking cavity 111, thereby improving the cooking effect.

[0109] Exemplarily, the shielding member 130 includes but is not limited to a shielding plate, and any shielding plate can be used as long as it can shield and close the window 112 , and no specific limitation is made herein.

[0110] In some embodiments, the driving mechanism 140 can drive the shielding member 130 to rotate relative to the device body 110 , and the shielding member 130 opens or closes the window 112 by rotating around a fixed axis.

[0111] In other embodiments, the driving mechanism 140 drives the shielding member 130 to slide along the first direction to open or close the window 112; illustratively, the driving mechanism 140 can drive the shielding member 130 to slide along the first direction to open or close the window 112, which is simple to implement and low cost.

[0112] Exemplarily, when the driving mechanism 140 drives the purification unit 120 to move from outside the cooking cavity 111 to inside the cooking cavity 111, the driving mechanism 140 drives the shielding member 130 to move along the first direction to open the window 112. For example, when the purification unit 120 moves to the position of the window 112, the window 112 is already opened, and the purification unit 120 enters the cooking cavity 111 through the window 112. When the driving mechanism 140 drives the purification unit 120 to move from inside the cooking cavity 111 to outside the cooking cavity 111, the driving mechanism 140 drives the shielding member 130 to move along the first direction to close the window 112. For example, when the purification unit 120 moves out of the cooking cavity 111 through the window 112, the shielding member 130 closes the window. In this way, the movement of the purification unit 120 and the movement of the shielding member 130 are linked to improve the efficiency of the purification unit 120 switching between inside and outside the cooking cavity 111 and improve the compactness of the structure.

[0113] In order to further improve the smoothness of movement and route accuracy of the shielding member 130, in an embodiment of the present application, a first sliding portion 1443 extending along a first direction is provided on the device body 110, and a second sliding portion is provided on the shielding member 130. The first sliding portion 1443 is configured to be slidably connected to the second sliding portion. In this way, when the driving mechanism 140 drives the shielding member 130 to move, the shielding member 130 slides along the first sliding portion 1443 through the second sliding portion to achieve guidance of the movement of the shielding member 130.

[0114] Exemplarily, the first sliding portion 1443 is one of a slide rail and a slide groove, and the second sliding portion is the other of the slide rail or the slide groove. In this way, the sliding smoothness and the accuracy of the movement path of the shielding member 130 are improved, and the structure is simple, easy to implement, and low cost.

[0115] Please refer to Figure 6 As shown, the cooking device 100 also includes a guide member 1442, which can be detachably arranged on the device body 110. For example, the guide member 1442 can be arranged on the device body 110 by means of magnetic connection, threaded connection or clamping, and the guide member 1442 has two relatively arranged slide grooves in the second direction, and the slide grooves extend along the first direction. At least part of the contours on both sides of the shielding member 130 are respectively located in the corresponding slide grooves, so that the shielding member 130 slides along the slide grooves under the action of the driving force, so as to facilitate the processing, manufacturing and replacement of the first sliding part 1443.

[0116] In some embodiments, the cooking device 100 also includes a base 1445, which is fixedly disposed on the device body 110, and the guide member 1442 is detachably disposed on the base 1445, or the guide member 1442 can be disposed on the base 1445 by bonding, welding, etc.

[0117] In order to further improve the smoothness of movement of the shielding member 130, in an embodiment of the present application, rolling members 1446 are respectively provided between the shielding member 130 and the top wall and the bottom wall of the slide groove, and the rolling members 1446 are respectively in rolling contact with the shielding member 130 and the groove wall of the slide groove, wherein the rolling member 1446 supports the shielding member 130 and enables the shielding member 130 to be in rolling contact with the rolling member 1446 when moving. In this way, the smoothness of the movement of the shielding member 130 is improved and the problem of sticking is avoided.

[0118] Exemplarily, the rolling element 1446 includes but is not limited to a ball, a bearing, etc. As long as it is in rolling contact with the shielding element 130 to reduce friction, no specific limitation is made here.

[0119] In addition, the driving mechanism 140 includes a driving motor 141 and a movable part 142. The movable part 142 is connected between the purification unit 120 and the power output end of the driving motor 141. The driving motor 141 is configured to provide power to the movable part 142 to drive the movable part 142 to move, so that the movable part 142 drives the purification unit 120 to approach or move away from the window 112, thereby making the purification unit 120 move through the window 112 to the inside or outside of the cooking cavity 111.

[0120] Please refer to Figure 7 and Figure 8 As shown, the movable part 142 can be a rotating part, which is connected to the output shaft of the driving motor 141, so that the driving motor 141 drives the rotating part to rotate, so as to drive the purification unit 120 to approach or move away from the window 112. In this way, the driving motor 141 can realize the forward or reverse rotation of the rotating part through forward and reverse rotation, thereby driving the purification unit 120 to move in the direction of approaching or moving away from the window 112. The structure is simple, easy to implement and low in cost.

[0121] For example, in Figure 7 and Figure 8 In the figure, the rotating part is a rotating arm, the output shaft of the driving motor 141 is connected to one end of the rotating arm, and the purification unit 120 is arranged at the other end of the rotating arm. In this way, when the driving motor 141 drives the rotating arm to rotate, the rotating arm drives the purification unit 120 to switch between the inside and outside of the cooking cavity 111 through the window 112.

[0122] For example, in Figure 7In the process, the driving motor 141 rotates forward (clockwise) to drive the rotating arm to drive the purification unit 120 to move out of the cooking cavity 111 and move away from the window 112. At this time, the shielding member 130 closes the window 112.

[0123] exist Figure 8 In the process, when the driving motor 141 reverses (rotates counterclockwise), the driving motor 141 drives the rotating arm to drive the purification unit 120 to move toward the direction close to the window 112. At this time, the covering member 130 opens the window 112, and the driving motor 141 continues to drive the rotating arm to move, so that the rotating arm drives the purification unit 120 to enter the cooking cavity 111 through the window 112, so as to achieve the purification and deodorization effect of the inside of the cooking cavity 111 through the purification unit 120.

[0124] In addition, please refer to Figure 7 and Figure 8 As shown, the device body 110 has a first limiting structure 150 and a second limiting structure 160. When the rotating member abuts against the first limiting structure 150 (as shown in FIG. Figure 8 ), the purification unit 120 moves into the cooking cavity 111; when the rotating member abuts against the second limiting structure 160 (as shown in Figure 7 As shown in FIG. 1 , the purification unit 120 moves to the outside of the cooking cavity 111, and the accuracy of switching the purification unit 120 between the inside and the outside of the cooking cavity 111 is improved by limiting the rotating member.

[0125] For example, Figure 7 and Figure 8 As shown in , the first limiting structure 150 and the second limiting structure 160 can both be limiting protrusions. The limiting structure is simple, easy to implement and low in cost.

[0126] In addition, the driving mechanism 140 also includes a transmission component 143, which is connected between the power output end of the driving motor 141 and the shielding member 130. The driving motor 141 is configured to drive the transmission component 143 to move to drive the shielding member 130 to open or close the window 112. The power is transmitted through the transmission component 143 to drive the shielding member 130 to open or close the window 112. The implementation method is simple and low in cost.

[0127] In some embodiments, please refer to Figure 2 and Figure 3 As shown, the transmission assembly 143 includes a gear set and a rack 1441, the shielding member 130 is arranged on the rack 1441, and the driving motor 141 is configured to drive the rack 1441 to move along the first direction through the gear set, so that the rack 1441 drives the shielding member 130 to open or close the window 112. The transmission assembly 143 has a simple structure, is easy to implement, and has low cost.

[0128] For example, Figure 3 As shown in the figure, the gear set includes a first gear 1431, a second gear 1432, a third gear 1433 and a fourth gear 1434; the first gear 1431 is connected to the output shaft of the driving motor 141, the second gear 1432 is externally meshed with the first gear 1431, the third gear 1433 is coaxially arranged with the second gear 1432, the fourth gear 1434 is externally meshed with the third gear 1433, and the rack 1441 is externally meshed with the fourth gear 1434. The power transmission is achieved through the gears, the force transmission is accurate, and the structure is simple.

[0129] In some embodiments, the window 112 is disposed on the rear wall of the cooking cavity 111 of the device body 110 , which can improve the structural compactness of the cooking device 100 and enhance the overall aesthetics of the cooking device 100 .

[0130] To improve deodorization efficiency, please refer to Figure 1 As shown, the cooking device 100 also includes a circulating fan 180, which is arranged on the rear side wall of the device body 110. A fan cover 190 is arranged on the outer side of the circulating fan 180. An air outlet 191 is arranged at a position of the fan cover 190 corresponding to the window 112. The air outlet 191 and the window 112 are connected to the inside and outside of the cooking cavity 111. The circulating fan 180 is configured to accelerate the flow efficiency of the airflow inside and outside the cooking cavity 111. In this way, the flow efficiency of the airflow inside the cooking cavity 111 can be improved, thereby improving the efficiency of removing odor in the cooking cavity 111.

[0131] Since the sealing of the cooking cavity 111 will affect the cooking effect, and the window 112 is provided on the cavity wall of the cooking cavity 111, the sealing of the cooking cavity 111 will be affected. Therefore, in the embodiment of the present application, please refer to Fig. 9 As shown, the cooking device 100 also includes a sealing component 200, which is arranged around the periphery of the window 112. When the covering member 130 closes the window 112, the sealing component 200 is at least arranged between the covering member 130 and the outer wall of the cooking cavity 111 to seal the gap between the covering member 130 and the periphery of the window 112, so as to improve the sealing of the cooking cavity 111 and avoid affecting the cooking effect due to poor sealing at the window 112 during cooking.

[0132] like Fig. 9 As shown in the figure, when the shielding member 130 moves along the first direction, the sealing assembly 200 is configured to expand and contract along the second direction under the action of the shielding member 130; wherein there is an angle between the first direction and the second direction, the first direction is, for example, the sliding direction of the shielding member 130, and the second direction is, for example, a direction perpendicular or approximately perpendicular to the first direction.

[0133] In a specific implementation, when the shielding member 130 moves along the first direction, when the shielding member 130 closes the window 112, the sealing assembly 200 is in a compressed state in the second direction due to the force applied by the shielding member 130, and the sealing assembly 200 seals the gap between the periphery of the window 112 and the shielding member 130, thereby improving the sealing of the cooking cavity 111; when the shielding member 130 moves in the opposite direction along the first direction so that the shielding member 130 opens the window 112, the sealing assembly 200 is located at the periphery of the window 112 and is in a freely retractable state.

[0134] In some embodiments, please refer to Figures 11 to 14 As shown, the sealing assembly 200 includes a sealing ring 210, which is arranged around the periphery of the window 112. When the covering member 130 closes the window 112, the sealing ring 210 is configured to seal the gap between the covering member 130 and the periphery of the window 112. In this way, the gap between the covering member 130 and the periphery of the window 112 can be effectively sealed, thereby improving the sealing of the cooking cavity 111.

[0135] Among them, the sealing ring 210 can be made of a material with certain elasticity and good sealing performance. For example, the material of the sealing ring 210 includes but is not limited to rubber, silicone and other materials. In this way, the sealing ring 210 is arranged around the window 112, which can improve the sealing performance of the cooking cavity 111 and prevent liquids from entering the cooking cavity 111 through the periphery of the window 112.

[0136] Please refer to Figures 11 to 14 As shown in , along the second direction, the sealing ring 210 has a first sealing portion 211, a second sealing portion 212 and an elastic portion 213, the elastic portion 213 is connected between the first sealing portion 211 and the second sealing portion 212, the first sealing portion 211 is configured to be connected to the shielding member 130, and the second sealing portion 212 is configured to be connected to the device body 110. In this way, the sealing ring 210 has a certain deformation amount in the second direction, so that the sealing ring 210 can be deformed with the movement of the shielding member 130 to improve the sealing effect of the cooking cavity 111. At the same time, the connection stability between the sealing ring 210 and the device body 110 and the shielding member 130 is also improved.

[0137] To further increase the deformation of the sealing ring 210, please continue to refer to Figures 11 to 14 As shown, the elastic portion 213 has a deformation structure 2131, and the deformation structure 2131 defines a deformation space 2132 for elastic expansion and contraction of the sealing ring 210 along the second direction to increase the deformation space of the sealing ring 210, thereby improving the flexibility of the sealing ring 210 in deformation under dynamic conditions and improving the sealing reliability of the sealing ring 210.

[0138] Exemplarily, the side edge of the elastic portion 213 along the second direction is a bending structure, the bending structure is formed into a deformation structure 2131, and the depression on the bending structure is formed into a deformation space 2132. In this way, under the extrusion force of the shielding member 130, the sealing ring 210 is in a compressed state, and the deformation space 2132 can provide a compression space for the elastic portion 213, which satisfies the deformation flexibility and sealing reliability of the sealing ring 210 under dynamic conditions, while having a simple structure, easy implementation and low cost.

[0139] Among them, Figures 11 to 14 As shown in the figure, the bending structure of the elastic part 213 can be an arc-shaped bending structure with a concave and convex shape connected in sequence to reduce the stress of the bending structure at the bending point and improve the strength of the sealing ring 210; and the first sealing part 211 and the second sealing part 212 can both be sealing gaskets to improve the fit between the first sealing part 211 and the shielding member 130 and the fit between the second sealing part 212 and the surface of the equipment body 110, so as to further improve the sealing effect of the cooking cavity 111.

[0140] Please continue to refer to Figures 11 to 14 As shown, the sealing assembly 200 also includes an elastic member 220, which is arranged between the first sealing portion 211 and the second sealing portion 212. The elastic member 220 is configured to drive the first sealing portion 211 and the second sealing portion 212 to move in directions away from each other through its own elastic force. In this way, the elastic member 220 can drive the sealing ring 210 to reset through its own elastic force, and automatically adjust the tightness between the sealing ring 210 and the device body 110 and the shielding member 130 through the elastic member 220 to adapt to different gap widths, thereby improving the sealing effect.

[0141] In a specific implementation, when the shielding member 130 closes the window 112, the elastic member 220 and the sealing ring 210 in the sealing assembly 200 are both in a compressed state, and the elastic member 220 can use its own elastic force to push the first sealing portion 211 and the second sealing portion 212 in opposite directions respectively, thereby improving the tightness between the first sealing portion 211 and the shielding member 130, and improving the tightness between the second sealing portion 212 and the device body 110; when the shielding member 130 opens the window 112, the shielding member 130 releases the squeezing force on the sealing assembly 200. At this time, the elastic member 220 drives the sealing ring 210 to reset by its own elastic force, so that the elastic portion 213 in the sealing ring 210 is in a freely extended state.

[0142] In order to further improve the sealing performance between the first sealing portion 211 and the shielding member 130, please refer to Fig.12 and Fig.13As shown, the first sealing portion 211 has at least one annular sealing protrusion 2111 on the side facing away from the elastic member 220. The sealing protrusion 2111 is arranged around the window 112. When the covering member 130 closes the window 112, the sealing protrusion 2111 abuts against the covering member 130. In this way, the sealing performance between the sealing assembly 200 and the covering member 130 can be further improved by the sealing protrusion 2111.

[0143] Among them, the sealing protrusion 2111 can be an elastic protrusion formed of a certain elastic material, the cross-section of the elastic protrusion can be a triangular, trapezoidal or other structure, and the cross-sectional size of the sealing protrusion 2111 facing the shielding member 130 is smaller than the size of the sealing protrusion 2111 away from the shielding member 130. In this way, when the shielding member 130 closes the window 112, the sealing protrusion 2111 is at least partially deformed to make the sealing protrusion 2111 and the shielding member 130 seal and abut against each other, thereby improving the sealing between the shielding member 130 and the sealing assembly 200, and then improving the sealing of the cooking cavity 111.

[0144] Please continue to refer to Figures 11 to 14 As shown, the sealing assembly 200 also includes a first support member 230 and a second support member 240. Along the second direction (for example, the vertical direction in the figure), the elastic member 220 is arranged between the first support member 230 and the second support member 240, the first sealing portion 211 is arranged on the side of the first support member 230 away from the elastic member 220, and the second sealing portion 212 is arranged on the side of the second support member 240 away from the elastic member 220, so as to provide a supporting basis for the sealing ring 210 through the first support member 230 and the second support member 240, thereby improving the overall stability and reliability of the sealing assembly 200.

[0145] Please continue to refer to Figures 11 to 14 As shown, the first support member 230 has a first guide protrusion 231 on the side facing the second support member 240, and the second support member 240 has a second guide protrusion 241 matching the first guide protrusion 231 on the side facing the first support member 230. The first guide protrusion 231 and the second guide protrusion 241 slide with each other along their extension direction to guide the extension and retraction of the elastic member 220, thereby improving the accuracy and reliability of the extension and retraction path of the sealing assembly 200, thereby improving the sealing reliability of the sealing assembly 200.

[0146] Among them, the first guide protrusion 231 can be a first guide sleeve, the second guide protrusion 241 and the second guide protrusion 241 are second guide sleeves, so that the first guide sleeve is sleeved on the second guide sleeve, and the elastic member 220 is located inside the second elastic sleeve, and the two ends are respectively abutted against the first support member 230 and the second support member 240, so that the compactness of the overall structure of the sealing assembly 200 can be improved.

[0147] In order to reduce the wear of the sealing ring 210 caused by the movement of the shielding member 130 relative to the sealing ring 210, therefore, in the embodiment of the present application, please refer to Figures 10 to 14 As shown in the figure, along the movement direction of the shielding member 130, the first support member 230 has a support protrusion 232 on the side away from the second support member 240, and the support protrusion 232 passes through the first sealing portion 211; the shielding member 130 has a guide groove 131 matching the support protrusion 232 on the side facing the support protrusion 232. When the shielding member 130 closes the window 112, the support protrusion 232 is located in the guide groove 131, and the elastic member 220 drives the first sealing portion 211 and the second sealing portion 212 to move in directions away from each other through its own elastic force to seal the gap between the shielding member 130 and the periphery of the window 112; when the shielding member 130 opens the window 112, the support protrusion 232 is located in the guide groove 131. The support protrusion 232 is located outside the guide groove 131, and the support protrusion 232 is supported between the shielding member 130 and the first support member 230. The elastic member 220 is in a compressed state so that there is a gap between the shielding member 130 and the first sealing portion 211. In this way, when the shielding member 130 closes the window 112, the effective sealing of the sealing assembly 200 on the periphery of the window 112 is improved, and when the shielding member 130 opens the window 112, the support protrusion 232 is supported between the shielding member 130 and the sealing ring 210 to protect the surface of the sealing ring 210 and avoid repeated friction between the surfaces of the shielding member 130 and the sealing ring 210, thereby extending the service life of the sealing ring 210.

[0148] In summary, in the cooking device provided in the embodiment of the present application, a purification unit and a shielding member are movably arranged on the device body, and a window is arranged on the device body, the shielding member can open or close the window, and when the shielding member opens the window, the purification unit can move into the cooking cavity or move out of the cooking cavity through the window under the action of force. In this way, when cooking is finished, the purification unit can be moved into the cooking cavity through the window to remove the residual taste of food in the cooking cavity through the purification unit; and when cooking, the purification unit is moved out of the cooking cavity to solve the problem that the purification unit is not resistant to high temperatures, thereby improving the taste of cooked food and the cooking experience of the user; in addition, a sealing component is arranged around the window, when the shielding member closes the window, the sealing component seals the gap between the shielding member and the periphery of the window to improve the sealing of the cooking cavity, thereby avoiding affecting the cooking effect due to poor sealing at the window during cooking.
