[0097] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application. The embodiments described below and the features in the embodiments can be combined with each other without conflict.

[0098] Please refer to Figure 1 Fig. 1 shows a cooking device 100 provided by an embodiment of the present application. The cooking device 100 comprises a device body 110. The device body 110 has a cooking cavity 111. The cooking cavity 111 is used for accommodating food to be cooked, i.e., the food can realize a cooking task in the cooking cavity 111.

[0099] The cooking device 100 includes but is not limited to a micro-steam oven, which combines the functions of a microwave oven, a steam oven, an oven, etc., and can realize multiple cooking tasks such as steaming, baking, frying, and microwaving in one cooking cavity 111, so that the user can complete diversified cooking in one device.

[0100] However, when cooking using these functions, the taste of food often remains in the cooking cavity 111, and this remaining taste can cause cross-contamination problems in subsequent cooking processes, affecting the taste of newly cooked food and the overall cooking experience.

[0101] In order to remove the residual taste of food in the cooking cavity 111, in some embodiments, a purifier is provided in the cooking cavity 111, which 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, and by releasing negative ions, the negative ions can combine with odor ions to remove odors in the cooking cavity 111, the odor removal method is simple, so as to remove the residual taste of food in the cooking cavity 111, improve the taste of cooked food, and further improve the user's experience.

[0102] However, the purifier is not resistant to high temperature, so placing the purifier in the cooking cavity 111 poses a certain safety hazard, resulting in poor safety and reliability of the cooking device 100.

[0103] Based on the above problems, in the embodiments of the present application, please refer to Figure 4 and Figure 5 The cavity wall of the cooking cavity of the device body 110 has a window 112 communicating the inside and outside of the cooking cavity 111, the purification unit 120 is movably arranged on the device body 110, the ionization unit 170 is fixedly arranged outside the cooking cavity 111 and fixedly connected with the device body 110, the purification unit 120 is electrically connected with the ionization unit 170, the purification unit 120 can enter the inside of 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 cooking is needed, the purification unit 120 can move out to the outside of the cooking cavity 111 through the window 112 to avoid the problem of damage to the purification unit 120 caused by high temperature in the cooking cavity 111; after cooking is finished, the purification unit 120 can enter the inside of the cooking cavity 111 through the window 112, so that the purification unit 120 can be started to work and remove the residual taste of food in the cooking cavity 111, thereby improving the taste of the next cooked food.

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

[0106] In this way, after the cooking is completed, 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 smell of food in the cooking cavity 111 by the purification unit 120; when the food needs to be cooked, the driving mechanism 140 drives the purification unit 120 to move through the window 112 and out of the cooking cavity 111, so as to solve the problem that the purification unit 120 is not resistant to high temperature, thereby improving the taste of the cooked food and the cooking experience of the user.

[0107] It should be noted that the driving mechanism 140 is arranged outside the cooking cavity 111, so that the problem that the driving mechanism 140 is not resistant to high temperature can be avoided, and in addition, the volume of the cooking cavity 111 can be increased, thereby improving the user's experience.

[0108] Since the window 112 is arranged on the cavity wall of the cooking cavity 111, the airtightness of the cooking cavity 111 during operation will be affected, therefore, in the embodiments of the present application, the cooking device 100 further comprises a shielding piece 130, the shielding piece 130 is movably arranged on the device body 110 and connected with the driving mechanism 140, the driving mechanism 140 drives the shielding piece 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 piece 130 can be driven to move, so that the shielding piece 130 opens the window 112 (as shown in FIG. 1B), and the driving mechanism 140 drives the purification unit 120 to enter the cooking cavity 111 through the window 112, so as to remove the residual smell of food in the cooking cavity 111; when the cooking needs to be started, the purification unit 120 moves out of the cooking cavity 111, the shielding piece 130 moves to the window 112 to close the window 112 (as shown in FIG. 1A), so that the cooking cavity 111 forms airtight cooking cavity 111, thereby improving the cooking effect. Figure 5 Figure 2 In this way, after the cooking is completed, 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 smell of food in the cooking cavity 111 by the purification unit 120; when the food needs to be cooked, the driving mechanism 140 drives the purification unit 120 to move through the window 112 and out of the cooking cavity 111, so as to solve the problem that the purification unit 120 is not resistant to high temperature, thereby improving the taste of the cooked food and the cooking experience of the user.

[0109] For example, the shielding piece 130 includes but is not limited to a shielding plate, as long as it can shield and close the window 112, which is not limited here.

[0110] In some embodiments, the driving mechanism 140 can drive the shielding piece 130 to rotate relative to the device body 110, and the shielding piece 130 rotates around a fixed axis to open or close the window 112.

[0111] ​In some embodiments, the driving mechanism 140 drives the shielding member 130 to slide along the first direction to open or close the window 112.

[0112] For example, 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 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, so that the movement of the purification unit 120 and the movement of the shielding member 130 are linked to improve the efficiency of switching the purification unit 120 between inside and outside of the cooking cavity 111, and improve the compactness of the structure.

[0113] In order to further improve the smoothness and accuracy of the movement of the shielding member 130, in the embodiments of the present application, the device body 110 has a first sliding part 1443 extending along the first direction, and the shielding member 130 has a second sliding part, the first sliding part 1443 is configured to be in sliding connection with the second sliding part, so that when the driving mechanism 140 drives the shielding member 130 to move, the shielding member 130 slides along the first sliding part 1443 through the second sliding part to realize the guidance of the movement of the shielding member 130.

[0114] For example, the first sliding part 1443 is one of a sliding rail and a sliding groove, and the second sliding part is the other one of the sliding rail and the sliding groove, so that the smoothness of the sliding of the shielding member 130 and the accuracy of the movement path are improved, and the structure is simple, easy to implement, and low in cost.

[0115] Please refer to Figure 6 As shown in the figure, the cooking device 100 further comprises a guide 1442 which is detachably arranged on the device body 110, for example, the guide 1442 can be arranged on the device body 110 by magnetic attraction connection, threaded connection or clamping, etc., the guide 1442 has two sliding grooves arranged oppositely in the second direction, the sliding grooves extend along the first direction, and at least part of the profiles of the two sides of the shielding member 130 are respectively located in the corresponding sliding grooves, so that the shielding member 130 slides along the sliding grooves under the action of the driving force, so as to facilitate the machining and replacement of the first sliding part 1443, etc.

[0116] In some embodiments, the cooking device 100 further comprises a base 1445 fixedly arranged on the device body 110, and the guide member 1442 is detachably arranged on the base 1445 or is arranged on the base 1445 by means of adhesion, welding or the like.

[0117] In order to further improve the smoothness of the movement of the shielding member 130, in the embodiments of the present application, a rolling member 1446 is arranged between the shielding member 130 and the top wall and the bottom wall of the sliding groove respectively, and the rolling member 1446 is in rolling contact with the shielding member 130 and the groove wall of the sliding groove respectively. The rolling member 1446 supports the shielding member 130 and makes the shielding member 130 in rolling contact with the rolling member 1446 when moving, so that the smoothness of the movement of the shielding member 130 is improved and the problem of jamming is avoided.

[0118] For example, the rolling member 1446 includes but is not limited to a ball bearing and the like, as long as it is in rolling contact with the shielding member 130 to reduce friction, and is not limited in detail here.

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

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

[0121] For example, in Figure 7 and Figure 8 , the rotating member is a rotating arm, the output shaft of the driving motor 141 is connected with one end of the rotating arm, and the purification unit 120 is arranged at the other end of the rotating arm, so that 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 middle, 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 piece 130 closes the window 112.

[0123] In Figure 8 the middle, when the driving motor 141 reverses (counterclockwise), the driving motor 141 drives the rotating arm to drive the purification unit 120 to move towards the window 112, at this time, the shielding piece 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, to achieve the purification and deodorization effect on the inside of the cooking cavity 111 by the purification unit 120.

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

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

[0126] In addition, the driving mechanism 140 further includes a transmission assembly 143 connected between the power output end of the driving motor 141 and the shielding piece 130, and the driving motor 141 is configured to drive the transmission assembly 143 to move, to drive the shielding piece 130 to open or close the window 112, and the transmission assembly 143 realizes the transmission of power to drive the shielding piece 130 to open or close the window 112, which is simple in implementation and low in cost.

[0127] In some embodiments, as shown in Figure 2 and Figure 3 , the transmission assembly 143 includes a gear set and a rack 1441, and the shielding piece 130 is arranged on the rack 1441, and the driving motor 141 is configured to drive the rack 1441 to move in a first direction through the gear set, to drive the shielding piece 130 to open or close the window 112, and the transmission assembly 143 is simple in structure, easy to implement, and low in cost.

[0128] As an example, as shown in Figure 3 As shown in FIG. 13, 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 with the output shaft of the driving motor 141, the second gear 1432 is externally engaged with the first gear 1431, the third gear 1433 is coaxially arranged with the second gear 1432, the fourth gear 1434 is externally engaged with the third gear 1433, and the rack 1441 is externally engaged with the fourth gear 1434; the power transmission is realized through the gears, the force transmission is accurate, and the structure is simple.

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

[0130] In order to improve the deodorization efficiency, please refer to Figure 1 As shown in FIG. 14, the cooking device 100 further includes a circulating fan 180 arranged on the rear side wall of the device body 110, and a fan cover plate 190 is arranged on the outer side of the circulating fan 180; the fan cover plate 190 is provided with an air outlet 191 at a position corresponding to the window 112, and the air outlet 191 and the window 112 are in communication with 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, which can improve the flow efficiency of the airflow inside the cooking cavity 111 and thus improve the efficiency of removing odors inside the cooking cavity 111.

[0131] Since the sealing performance of the cooking cavity 111 affects the cooking effect, and the arrangement of the window 112 on the cavity wall of the cooking cavity 111 affects the sealing performance of the cooking cavity 111, in the embodiments of the present application, please refer to Figure 9 As shown in FIG. 15, the cooking device 100 further includes a sealing assembly 200 arranged around the window 112; when the shielding piece 130 closes the window 112, the sealing assembly 200 is arranged at least between the shielding piece 130 and the outer wall of the cooking cavity 111 to seal the gap between the shielding piece 130 and the periphery of the window 112, so as to improve the sealing performance of the cooking cavity 111 and avoid affecting the cooking effect due to poor sealing performance at the window 112 during cooking.

[0132] As shown in Figure 9 As shown in FIG. 16, when the shielding piece 130 moves in the first direction, the sealing assembly 200 is configured to stretch and contract in the second direction under the action of the shielding piece 130; the first direction and the second direction have an included angle therebetween, for example, the sliding direction of the shielding piece 130 is the first direction, and the direction perpendicular or approximately perpendicular to the first direction is the second direction.

[0133] In a specific implementation, when the shielding member 130 moves along the first direction and the shielding member 130 closes the window 112, the sealing assembly 200 is compressed 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 performance of the cooking cavity 111; when the shielding member 130 moves reversely along the first direction and 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 free and elastic state.

[0134] In some embodiments, as shown in Figures 11 to 14 the sealing assembly 200 includes a sealing ring 210, which surrounds the periphery of the window 112, and is configured to seal the gap between the shielding member 130 and the periphery of the window 112 when the shielding member 130 closes the window 112, so that the gap between the shielding member 130 and the periphery of the window 112 can be effectively sealed, thereby improving the sealing performance of the cooking cavity 111.

[0135] 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 the like, so that the sealing ring 210 surrounds the periphery of the window 112, which can improve the sealing performance of the cooking cavity 111 and prevent liquid and the like from entering the cooking cavity 111 through the periphery of the window 112.

[0136] As shown in Figures 11 to 14 in 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 with the shielding member 130, and the second sealing portion 212 is configured to be connected with the device body 110, so that the sealing ring 210 has a certain deformation amount in the second direction, thereby enabling the sealing ring 210 to deform with the movement of the shielding member 130 to improve the sealing effect of the cooking cavity 111, and also improve the connection stability between the sealing ring 210 and the device body 110 and the shielding member 130.

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

[0138] Exemplarily, the side edge of the elastic part 213 in the second direction is a bending structure, the bending structure is formed as a deformation structure 2131, and the recess on the bending structure is formed as a deformation space 2132. In this way, under the extrusion of the shielding piece 130, the elastic part 213 is in a compressed state, and the deformation space 2132 can provide a compression space for the elastic part 213, so as to meet the deformation flexibility and sealing reliability of the sealing ring 210 under dynamic conditions, while the structure is simple, easy to implement, and low in cost.

[0139] In the formula, as shown in Figures 11 to 14 , the bending structure of the elastic part 213 can be a concave-convex-shaped arc bending structure connected in sequence, so as to reduce the stress of the bending structure at the bending position and improve the strength of the sealing ring 210; and the first sealing part 211 and the second sealing part 212 can each be a sealing gasket, so as to improve the fit between the first sealing part 211 and the shielding piece 130 and the fit between the second sealing part 212 and the surface of the equipment body 110, and further improve the sealing effect of the cooking cavity 111.

[0140] Please continue to refer to Figures 11 to 14 , the sealing assembly 200 further includes an elastic piece 220, which is arranged between the first sealing part 211 and the second sealing part 212. The elastic piece 220 is configured to drive the first sealing part 211 and the second sealing part 212 to move in directions away from each other by the elastic force of the elastic piece 220. In this way, the elastic piece 220 can reset the sealing ring 210 by the elastic force of the elastic piece 220, and automatically adjust the tightness between the sealing ring 210 and the equipment body 110 and the shielding piece 130, respectively, to adapt to different gap widths, thereby improving the sealing effect.

[0141] In specific implementation, when the shielding piece 130 closes the window 112, the elastic piece 220 and the sealing ring 210 in the sealing assembly 200 are in a compressed state. The elastic piece 220 can push the first sealing part 211 and the second sealing part 212 in opposite directions by the elastic force of the elastic piece 220, so as to improve the tightness between the first sealing part 211 and the shielding piece 130 and the tightness between the second sealing part 212 and the equipment body 110. When the shielding piece 130 opens the window 112, the shielding piece 130 releases the extrusion force on the sealing assembly 200. At this time, the elastic piece 220 drives the sealing ring 210 to reset by the elastic force of the elastic piece 220, so that the elastic part 213 in the sealing ring 210 is in a free elongation state.

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

[0143] The sealing protrusion 2111 can be an elastic protrusion formed of a material with elasticity. The cross section of the elastic protrusion can be triangular or trapezoidal. The cross section of the end of the sealing protrusion 2111 facing the shielding member 130 is smaller than the cross section of the end of the sealing protrusion 2111 away from the shielding member 130. When the shielding member 130 closes the window 112, the sealing protrusion 2111 is deformed at least partially to abut against the shielding member 130. In this way, the sealing performance between the shielding member 130 and the sealing assembly 200 is improved, and the sealing performance of the cooking cavity 111 is improved.

[0144] Please continue to refer to Figures 11 to 14 As shown, the sealing assembly 200 further includes a first support 230 and a second support 240. The elastic member 220 is arranged between the first support 230 and the second support 240 along the second direction (e.g., the vertical direction in the figure). The first sealing part 211 is arranged on the side of the first support 230 away from the elastic member 220. The second sealing part 212 is arranged on the side of the second support 240 away from the elastic member 220. The first support 230 and the second support 240 provide a support basis for the sealing ring 210, 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 side of the first support 230 facing the second support 240 has a first guide protrusion 231. The side of the second support 240 facing the first support 230 has a second guide protrusion 241 matched with the first guide protrusion 231. The first guide protrusion 231 and the second guide protrusion 241 slide relative to each other along the extension direction of the first guide protrusion 231 and the second guide protrusion 241 to guide the extension and contraction of the elastic member 220. In this way, the accuracy and reliability of the extension and contraction path of the sealing assembly 200 are improved, and the sealing reliability of the sealing assembly 200 is improved.

[0146] The first guide protrusion 231 can be a first guide sleeve, and the second guide protrusion 241 can be a second guide sleeve. The first guide sleeve is arranged on the second guide sleeve, and the elastic member 220 is arranged inside the second guide sleeve with both ends abutting against the first support 230 and the second support 240. In this way, the compactness of the overall structure of the sealing assembly 200 is improved.

[0147] In order to reduce the abrasion of the sealing ring 210 caused by the movement of the shielding piece 130 relative to the sealing ring 210, in the embodiment of the present application, as shown in Figures 10 to 14 the first support piece 230 has a support protrusion 232 on the side away from the second support piece 240 along the movement direction of the shielding piece 130, and the support protrusion 232 penetrates the first sealing part 211; the shielding piece 130 has a guide groove 131 on the side facing the support protrusion 232, which matches the support protrusion 232; when the shielding piece 130 closes the window 112, the support protrusion 232 is located in the guide groove 131, and the elastic piece 220 drives the first sealing part 211 and the second sealing part 212 to move away from each other by the elastic force of the elastic piece 220, so as to seal the gap between the shielding piece 130 and the periphery of the window 112; when the shielding piece 130 opens the window 112, the support protrusion 232 is located outside the guide groove 131, and the support protrusion 232 is supported between the shielding piece 130 and the first support piece 230, and the elastic piece 220 is in a compressed state, so that there is a gap between the shielding piece 130 and the first sealing part 211. In this way, the effective sealing of the sealing assembly 200 to the periphery of the window 112 when the shielding piece 130 closes the window 112 is improved, and the support protrusion 232 is supported between the shielding piece 130 and the sealing ring 210 when the shielding piece 130 opens the window 112, so as to protect the surface of the sealing ring 210 and avoid repeated friction between the shielding piece 130 and the surface of the sealing ring 210, thereby prolonging the service life of the sealing ring 210.

[0148] In summary, in the cooking equipment provided by the embodiment of the present application, a purification unit and a shielding piece are movably arranged on the equipment body, and a window is arranged on the equipment body, the shielding piece can open or close the window, and when the shielding piece opens the window, the purification unit can move into or out of the cooking cavity through the window under the action of a force. In this way, after cooking, the purification unit can move into the cooking cavity through the window to remove the smell of food residues in the cooking cavity by the purification unit. When cooking, the purification unit is moved out of the cooking cavity to solve the problem of poor high-temperature resistance of the purification unit, thereby improving the taste of cooked food and the cooking experience of the user. In addition, a sealing assembly is arranged around the window, and when the shielding piece closes the window, the sealing assembly seals the gap between the shielding piece and the periphery of the window, so as to improve the sealing performance of the cooking cavity and avoid affecting the cooking effect due to poor sealing performance at the window during cooking.
