[0053] Embodiment 1

[0054] This embodiment provides a cooking device with a steam cooking function, which can realize automatic door opening and closing of the cooking device, thereby improving the reliability of the cooking device. The cooking device can be a cooking device with a steam cooking function such as a steamer, a steam-bake combination machine, etc.

[0055] like Figure 1 , Figure 3 and Figure 5 As shown, the cooking device includes a body, a door 300 and a steam cooking module. The body includes an inner pot 600, and the inner pot 600 has a cooking cavity with a front opening; the door 300 is movably mounted on the front side of the body and can open or close the front opening of the cooking cavity; the steam cooking module is used to provide hot steam into the cooking cavity to cook the food in the cooking cavity.

[0056] In order to discharge the steam in the cooking cavity, the machine body further includes a hood 400 located at the top of the inner pot 600, and the hood 400 has a heat dissipation duct, which is connected to the cooking cavity, and has an exhaust port 401. During the cooking process or after cooking, the steam in the cooking cavity is discharged into the heat dissipation duct and discharged through the exhaust port 401. Furthermore, a heat dissipation fan 900 is provided on the top of the inner pot 600, and the heat dissipation fan 900 guides the external cooling air flow into the heat dissipation duct and cools and dissipates the hot steam to prevent the steam discharged from the machine body from being overheated and scalding the user.

[0057] In order to realize automatic door opening and closing of the cooking device, a lock component 200 is provided on the top of the door 300, and the door 300 has an installation cavity located above the hood 400 and separated from the heat dissipation duct, and an installation hole 50311 is provided at the bottom of the installation cavity. The cooking device also includes a door lock device 100, which includes a door lock drive mechanism 1 and a door lock assembly 2. The door lock drive mechanism 1 is located in the installation cavity; the door lock assembly 2 includes a lock shaft 21 and a door hook 22. The lock shaft 21 movably passes through the installation hole 50311, and the first end of the lock shaft 21 is located in the installation cavity and is transmission-connected to the door lock drive mechanism 1, and the second end of the lock shaft 21 extends out of the installation cavity and is connected to the door hook 22. The door lock drive mechanism 1 drives the door lock assembly 2 to switch between an unlocked state in which the door hook 22 can be separated from the lock component 200 and a locked state in which the door hook 22 can be locked with the lock component 200.

[0058] The door lock assembly 2 is partially opposite to the heat dissipation duct, and the heat dissipation duct guides the airflow to flow through the lock shaft 21. In order to prevent the airflow from entering the installation cavity through the installation hole 50311, in this embodiment, the door lock device 100 also includes a stop structure, which stops the air flowing through the door hook 22 from flowing through the installation hole 50311 to the installation cavity.

[0059] The cooking device provided in this embodiment can stop the airflow flowing through the door hook 22 in the heat dissipation duct from flowing into the installation cavity through the installation hole 50311 by setting a stop structure, so that the door lock drive mechanism 1 can be installed inside the installation cavity and the door hook 22 extends outside the installation cavity. At the same time, it can prevent the steam in the heat dissipation duct from entering the installation cavity through the installation hole 50311, thereby preventing the steam from corroding the door lock drive mechanism 1 and other structures in the installation cavity, thereby ensuring the safety of the cooking device and improving the installation convenience of the door lock device 100.

[0060] In this embodiment, the front end of the air cover 400 has an exhaust port 401 of the heat dissipation duct. To improve the installation convenience of the door lock assembly 2, the bottom of the installation cavity has a bottom structure 5031 that extends forward from the air cover 400. The installation hole 50311 is opened in the bottom structure 5031, and the lock shaft 21 is at least partially located at the front side of the heat dissipation duct. This arrangement allows the lock shaft 21 to extend vertically downward from the installation hole 50311, avoiding installation difficulties caused by the lock shaft 21 passing through the air cover 400, and also facilitates the lock shaft 21 and the door hook 22 to extend forward from the front side of the inner liner 600, thereby facilitating the cooperation between the door hook 22 and the lock component 200.

[0061] The machine body includes a casing 700 and a front frame 800. The front frame 800 is arranged around the front side of the inner liner 600 and the upper end is arranged higher than the inner liner 600. The machine body is wrapped around the outer side of the inner liner 600 and forms the overall appearance of the machine body. The front side of the inner liner 600 and the front side of the casing 700 are both fastened to the front frame 800. A top support plate is arranged on the top of the inner liner 600, and the wind shield 400 is installed on the upper side of the top support plate. The upper part of the front frame 800 is installed with a control device 500. The control device 500, the top of the wind shield 400 and the casing 700 are arranged to form the above-mentioned installation cavity.

[0062] It is understandable that the structures of the casing 700, the liner 600, the top support plate and the door 300 can be specifically configured with reference to the prior art, which is not the focus of the present invention and will not be described in detail here.

[0063] Furthermore, the control device 500 is located above the inner liner 600 and extends forward from the front side of the inner liner 600. The control device 500 includes a panel bracket 503, a control component 502 mounted on the panel bracket 503, and a front panel 501 covering the front side of the control component 502. The panel bracket 503 is fastened to the front frame 800. The panel bracket 503 includes a vertically arranged front panel portion, the periphery of the front panel portion is folded backward to form a side panel portion, the side panel portion and the front panel portion are surrounded to form an installation space, the front panel portion is provided with an installation opening, the control component 502 is installed in the installation space, and the control component of the control component 502 is arranged opposite to the installation opening to be exposed forward, and the front panel 501 is covered on the outer side of the front panel portion. The specific structure of the control device 500 can be set with reference to the prior art, which is not the focus of this embodiment and will not be limited or repeated this time.

[0064] The side plate portion located at the lower side of the front plate portion forms the above-mentioned bottom structure 5031, and the bottom structure 5031 extends backward and is placed on the top of the front end of the air hood 400, so that the bottom structure 5031 extends forward from the front side of the inner liner 600, so that the lock shaft 21 and the door lock extend forward from the front side of the inner liner 600 to facilitate the cooperation with the lock component 200. By arranging the bottom structure 5031 on the panel bracket 503 of the control device 500, the front side of the control device 500 can be flush with the closed door 300, and the lock shaft 21 can extend vertically downward from the bottom structure 5031, thereby improving the installation convenience of the door lock assembly 2 on the bottom structure 5031 and simplifying the arrangement of the bottom structure 5031.

[0065] In other embodiments, the air shield 400 may extend forward from the front side of the inner liner 600, and the locking shaft 21 may pass through the air shield 400. That is, the upper side of the air shield 400 forms the above-mentioned bottom structure 5031.

[0066] In this embodiment, the lock component 200 is installed in the middle of the machine door 300 along the left-right direction, and the door lock assembly 2 is installed in the middle of the machine body along the left-right direction, thereby improving the force balance of the machine door 300 during opening and closing.

[0067] like Figure 3 and Figure 4 As shown, it is worth mentioning that the door hook 22 has a lock slot 221. When the door lock assembly 2 is in an unlocked state, the notch of the lock slot 221 faces forward, so that the lock component 200 can enter and exit the lock slot 221 along the front and rear directions, so that the machine door 300 can be opened relative to the machine body. When the door lock assembly 2 is in a locked state, the notch of the lock slot 221 faces left and right directions to limit the lock component 200 from moving forward and out of the lock slot 221.

[0068] Furthermore, a guide surface 222 is formed on the front side surface of the door hook 22, and the guide surface 222 is located on the front side of the lock slot 221 and extends forward from the notch of the lock slot 221 in a direction away from the notch of the lock slot 221. When the user closes the door and the door hook 22 is in the locked position, the lock component 200 first contacts the guide surface 222. During the process of the user closing the door, the lock component 200 pushes the guide surface 222 from front to back, causing the door hook 22 to rotate in the direction toward the unlocked position, thereby guiding the lock component 200 to enter the lock slot 221 of the door hook 22, thereby realizing the user's manual door closing operation.

[0069] In this embodiment, the lock shaft 21 is arranged vertically to improve the installation convenience of the lock shaft 21. In other embodiments, the lock shaft 21 can also be arranged obliquely relative to the vertical direction, such as the lock shaft 21 is arranged obliquely forward from top to bottom.

[0070] like Figure 4 and Figure 5 As shown, in this embodiment, the stop structure includes a mounting seat 3 and a shaft seal 4. The mounting seat 3 is installed on the opening plane of the mounting hole 50311. A rotating shaft hole is opened on the mounting seat 3. The lock shaft 21 is rotatably passed through the rotating shaft hole and cooperates with the clearance of the rotating shaft hole, that is, the lock shaft 21 and the rotating shaft hole are radially limited to limit the radial movement of the lock shaft 21 in the rotating shaft hole; the door hook 22 is located on the side of the mounting seat 3 away from the mounting cavity, and the shaft seal 4 is at least partially clamped between the mounting seat 3 and the opening plane.

[0071] By providing the mounting seat 3, it is convenient to install the door lock assembly 2 on the bottom structure 5031, thereby improving the convenience of disassembly and assembly of the door lock assembly 2 and the door lock device 100 on the body, and at the same time, it is convenient to realize the rotation installation of the lock shaft 21, ensuring the rotation reliability and stability of the lock shaft 21; by providing the shaft seal 4, the gap between the opening plane of the mounting hole 50311 and the mounting seat 3 can be sealed to prevent the airflow from entering the mounting cavity through the gap between the mounting seat 3 and the opening plane; furthermore, due to the clearance between the lock shaft 21 and the rotating shaft hole, the reliability and smoothness of the rotation of the lock shaft 21 can be ensured, and it can also be prevented that the rotating shaft hole is too large, so that the airflow enters the installation cavity through the gap between the hole wall of the rotating shaft hole and the lock shaft 21. Specifically, the shaft seal 4 is sandwiched between the mounting seat 3 and the bottom structure 5031.

[0072] In another embodiment, the stop structure includes a mounting seat 3, which is fitted and fixedly mounted on the opening plane of the mounting hole 50311, the mounting seat 3 is provided with a rotating shaft hole connected to the mounting hole 50311, the lock shaft 21 is rotatably passed through the rotating shaft hole and is gap-matched with the rotating shaft hole, and the door hook 22 is located on the side of the mounting seat 3 away from the mounting cavity. Thus, by fitting the mounting seat 3 on the opening plane, the airflow is stopped from entering the mounting cavity through the gap between the mounting seat 3 and the opening plane. In this embodiment, the shaft seal 4 may not be provided.

[0073] In another embodiment, the stop structure only includes the shaft seal 4 but not the mounting seat 3. The shaft seal 4 is sleeved on the outside of the lock shaft 21, and the shaft seal 4 blocks the gap between the hole wall of the mounting hole 50311 and the outer wall of the lock shaft 21, thereby blocking the gap between the hole wall of the mounting hole 50311 and the outer wall of the lock shaft 21 by the shaft seal 4, and stopping the airflow from entering the mounting cavity through the gap.

[0074] In this embodiment, the mounting seat 3 is mounted on the upper side of the bottom structure 5031 to avoid the problem of the mounting seat 3 being exposed, which may cause the cooking device to have a poor aesthetic appearance and bump against the user, thereby improving the aesthetic appearance of the cooking device. In other embodiments, the mounting seat 3 may also be mounted on the lower side of the bottom structure 5031.

[0075] The mounting seat 3 is preferably detachably connected to the bottom structure 5031 to ensure the convenience of disassembly and assembly of the door lock assembly 2, and facilitate the disassembly and replacement of the mounting seat 3. Specifically, the mounting seat 3 and the bottom structure 5031 are connected by fastening screws penetrating the two. In other embodiments, the mounting seat 3 and the bottom structure 5031 can be clamped or welded.

[0076] In order to improve the installation stability and sealing reliability of the shaft seal 4, in this embodiment, an annular limiting groove 42 is provided on the outer side of the shaft seal 4, and the edge of the mounting hole 50311 is inserted into the limiting groove 42. By providing the limiting groove 42, the installation stability of the shaft seal 4 at the mounting hole 50311 can be improved, and the shaft seal 4 can be prevented from falling out of the mounting hole 50311, thereby better ensuring the sealing reliability of the shaft seal 4 to the gap.

[0077] Furthermore, the shaft seal 4 is wrapped around the outside of the lock shaft 21 and rotates with the lock shaft 21, so that the shaft seal 4 can seal the gap between the hole wall of the mounting hole 50311 and the lock shaft 21, preventing the airflow from flowing upward along the axial direction of the lock shaft 21 into the mounting cavity, thereby further ensuring the sealing effect of the shaft seal 4.

[0078] Since the shaft seal 4 and the lock shaft 21 rotate together, in order to ensure the sealing of the shaft seal 4 and the smooth rotation of the lock shaft 21 at the same time, the inner ring of the shaft seal 4 has a shaft sealing ring portion 41, and the thickness of the shaft sealing ring portion 41 gradually decreases in the direction toward the lock shaft 21, thereby making the main structure thickness of the shaft seal 4 relatively thick to facilitate the installation of the shaft seal 4 on the bottom structure 5031, and the thickness of the part of the shaft seal 4 that contacts the lock shaft 21 is relatively thin, so that the shaft sealing ring portion 41 can wrap the lock shaft 21, and the inner end of the shaft sealing ring portion 41 has a strong deformation ability, so that the setting of the shaft sealing ring portion 41 will not affect the rotation of the lock shaft 21, and can reduce the wear on the shaft sealing ring portion 41.

[0079] Furthermore, at least two shaft sealing rings 41 are provided at intervals along the axial direction of the lock shaft 21 to better ensure the sealing effect. In this embodiment, two shaft sealing rings 41 are provided, and the two shaft sealing rings 41 are respectively located on opposite sides of the limiting groove 42 along the axial direction of the lock shaft 21, so as to simplify the structure of the shaft seal 4 while ensuring the sealing effect.

[0080] It is worth noting that when the stop structure only includes the shaft seal 4, the matching structure between the shaft seal 4 and the mounting hole 50311 and the lock shaft 21 can refer to the above-mentioned structure setting, that is, a limiting groove 42 is set on the outer side of the shaft seal 41 and a shaft sealing ring part 41 is set on the inner side.

[0081] The mounting seat 3 is provided with a sealing groove 31 on one side facing the opening plane, and the sealing groove 31 is communicated with the rotating shaft hole. One end of the shaft seal 4 is located in the mounting hole 50311 and the other end is located in the sealing groove 31. The shaft seal 4 forms a first sealing portion and a second sealing portion on opposite sides of the limiting groove 42, respectively. The first sealing portion is located in the mounting hole 50311, and the second sealing portion is squeezed in the sealing groove 31 and squeezed between the groove wall of the sealing groove 31 and the opening plane at the upper end of the mounting hole 50311, thereby better ensuring the sealing reliability of the shaft seal 4 to the gap between the mounting seat 3 and the opening plane at the upper end of the mounting hole 50311; at the same time, the setting of the sealing groove 31 allows the mounting seat 3 and the opening plane to be fitted together, so as to facilitate the installation and fastening of the two.

[0082] In other embodiments, the second sealing portion may also be directly sandwiched between the bottom surface of the mounting seat 3 and the opening plane of the mounting hole 50311 .

[0083] Furthermore, the sealing groove 31 is in a frustum shape, with its large end facing the mounting hole 50311, and the second sealing portion is a frustum-shaped structure. The peripheral side surface of the second sealing portion fits with the frustum surface of the sealing groove 31, thereby increasing the contact area between the groove wall of the sealing groove 31 and the second sealing portion, improving the extrusion effect of the groove wall of the sealing groove 31 on the second sealing portion, and ensuring the sealing effect.

[0084] In this embodiment, the side wall of the lock shaft 21 is provided with a limit ring portion 23 protruding outward, the limit ring portion 23 is located outside the installation cavity and is spaced apart from the opening plane at the lower end of the installation hole 50311, and the first sealing portion of the shaft seal 4 is squeezed between the limit ring portion 23 and the opening plane at the lower end of the installation hole 50311. Specifically, the first sealing portion is squeezed between the limit ring portion 23 and the lower side surface of the bottom structure 5031. This arrangement can realize the squeezing of the limit ring portion 23 on the first sealing portion to achieve the squeezing of the limit ring portion 23 on the shaft sealing ring portion 41, thereby ensuring the wrapping reliability of the sealing shaft seal 4 on the lock shaft 21; at the same time, by setting the cooperation between the limit ring portion 23 and the shaft seal 4, the lock shaft 21 can be limited from moving upward along its axial direction, thereby ensuring the rotation reliability of the lock shaft 21.

[0085] It is worth noting that the mounting hole 50311 is set through and has a certain length, that is, the mounting hole 50311 has two opening planes set opposite to each other, that is, in this embodiment, the two opening planes of the mounting hole 50311 are formed on the upper and lower sides of the bottom structure 5031 respectively.

[0086] In this embodiment, the door lock drive mechanism 1 includes a drive assembly 11, a slider 12 and a connecting rod 13. The drive assembly 11 drives the slider 12 to slide in a preset direction. The first end of the connecting rod 13 is connected to the slider 12. A connecting member 24 is provided on the lock shaft 21. The second end of the connecting rod 13 is hinged to the connecting member 24 through a hinge shaft, and the hinge shaft is parallel to the lock shaft 21 and is arranged at intervals. The sliding of the slider 12 drives the connecting rod 13 to move, thereby pushing the connecting member 24 to rotate around the axis of the hinge shaft, and then pushing the lock shaft 21 to rotate around its axis. This arrangement can improve the flexibility of the position setting of the drive assembly 11, thereby improving the installation convenience of the door lock drive mechanism 1. In this embodiment, the slider 12 slides in the left-right direction, the connecting rod 13 is arranged roughly in the left-right direction, and the drive assembly 11 is installed in one side of the installation cavity along the left-right direction.

[0087] However, it is understandable that in other embodiments, the door lock drive mechanism 1 may also adopt other structural forms, as long as the door lock drive mechanism 1 can ensure that the lock shaft 21 can rotate around its axis. The present invention does not limit the specific structure of the door lock drive mechanism 1 and its installation structure in the installation cavity.

[0088] It is worth noting that in this embodiment, the lower end of the door 300 is hinged to the machine body through a hinge mechanism, and the hinge mechanism always applies an elastic force to the closed door 300 to flip the door 300 outward relative to the machine body, so that when the door lock device 100 and the lock component 200 are unlocked, the door 300 can automatically flip outward under the elastic force of the hinge mechanism, and the door 300 can be automatically opened, thereby improving the convenience of opening the door of the cooking device and improving the convenience and user experience of the cooking device. In other embodiments, the door 300 can only be opened manually by the user.

[0089] Embodiment 2

[0090] This embodiment provides a cooking device, and the basic structure of the cooking device provided in this embodiment is the same as that of the first embodiment, and only the setting of the stop structure is different. This embodiment will no longer repeat the structure that is the same as that of the first embodiment.

[0091] like Figure 6-Figure 9 As shown, in this embodiment, the door lock device 100 includes an adjustment seat 5, which can be slidably mounted on the body in the front-to-back direction, and a mounting shaft hole 54 is provided on the adjustment seat 5. The lock shaft 21 is rotatably inserted into the mounting shaft hole 54 and is clearance-matched with the mounting shaft hole 54. The mounting hole 50311 can allow the lock shaft 21 to move in the front-to-back direction. That is, the lock shaft 21 is radially limitedly matched with the mounting shaft hole 54 to limit the lock shaft 21 from moving radially in the mounting shaft hole 54.

[0092] By providing an adjustment seat 5, and the installation position of the adjustment seat 5 on the machine body can be adjusted in the front-to-back direction, the position of the lock shaft 21 installed on the adjustment seat 5 relative to the machine body in the front-to-back direction can be adjusted, that is, the position of the door hook 22 in the front-to-back direction can be adjusted, thereby ensuring the reliability of the matching position between the door hook 22 and the lock component 200, avoiding the problem that the door hook 22 is too forward relative to the preset matching position, causing the lock component 200 to squeeze the door hook 22, and avoiding the problem that the door hook 22 is too backward relative to the preset matching position, causing the lock component 200 to be unable to smoothly push the door lock assembly 2 to rotate to the unlocking position for the lock component 200 to be inserted into the lock slot 221.

[0093] In this embodiment, the stop structure includes a first seal 7, which is sleeved on the outer side of the lock shaft 21 and fixed relative to the adjustment seat 5. The first seal 7 stops the airflow from flowing along the axial direction of the lock shaft 21 and the first seal 7 stops the airflow from flowing along the gap between the sliding mounting plane of the adjustment seat 5 and the adjustment seat 5. The setting of the first seal 7 can block the gap between the adjustment seat 5 and the sliding mounting plane of the adjustment seat 5 to prevent the airflow from flowing into the installation cavity along the gap, and can also stop the airflow from entering the installation cavity along the axial direction of the lock shaft 21, and the sealing effect is better.

[0094] In another embodiment, the first seal 7 can only stop the airflow from flowing along the axial direction of the lock shaft 21, and the gap between the adjustment seat 5 and its sliding mounting surface is controlled by the matching gap between the two to limit the airflow from flowing in the gap. In another embodiment, the first seal 7 can only stop the airflow from flowing along the gap between the adjustment seat 5 and the sliding mounting surface, and the gap between the adjustment seat 5 and the lock shaft 21 is set by the matching gap to reduce the probability of the airflow flowing into the mounting cavity through the gap.

[0095] In the present embodiment, the stop structure further comprises a fixed seat 6, the fixed seat 6 is mounted on the opening plane of the mounting hole 50311, and the adjusting seat 5 is slidably mounted on the side of the fixed seat 6 away from the opening plane. That is, the side of the fixed seat 6 away from the opening plane of the mounting hole 50311 forms the above-mentioned sliding mounting surface. By providing the fixed seat 6, the sliding mounting convenience and reliability of the adjusting seat 5 can be improved, and it is avoided to directly provide a sliding mounting structure for cooperating with the adjusting seat 5 on the machine body, simplifying the structure of the machine body, and improving the overall disassembly and assembly convenience of the door lock device 100. Specifically, the fixed seat 6 is mounted on the upper side of the bottom structure 5031. In other embodiments, the adjusting seat 5 can also be directly slidably mounted on the bottom structure 5031.

[0096] To ensure the sealing effect, in this embodiment, the first seal 7 blocks the gap between the hole wall of the mounting shaft hole 54 and the lock shaft 21, and the first seal 7 blocks the gap between the adjustment seat 5 and the fixed seat 6. In other embodiments, the first seal 7 may only block the gap between the mounting shaft hole 54 and the lock shaft 21, or only block the gap between the adjustment seat 5 and the fixed seat 6.

[0097] In order to better fix the first seal 7 relative to the adjusting seat 5, one of the first seal 7 and the adjusting seat 5 is convexly provided with an inserting convex ring 73, and the other is provided with an inserting groove 55. The inserting convex ring 73 is inserted in the inserting groove 55 with interference fit. Thus, through the cooperation of the inserting convex ring 73 and the inserting groove 55, the installation positioning and limiting of the first seal 7 on the adjusting seat 5 are achieved, ensuring that the sliding of the adjusting seat 5 relative to the fixed seat 6 drives the first seal 7 to move synchronously, thereby ensuring the sealing effect.

[0098] In this embodiment, the first sealing member 7 is provided with an inserting convex ring 73, and the adjusting seat 5 is provided with an inserting groove 55. In other embodiments, the first sealing member 7 may be provided with an inserting groove 55, and the adjusting seat 5 may be provided with an inserting convex ring 73.

[0099] Furthermore, on the horizontal projection plane, the orthographic projection of the shaft through hole 61 is always located inside the outer contour of the orthographic projection of the first sealing member 7. Therefore, when the adjusting seat 5 slides relative to the fixing seat 6, the first sealing member 7 is always partially sandwiched between the adjusting seat 5 and the fixing seat 6 to seal the gap between the adjusting seat 5 and the fixing seat 6, thereby ensuring the reliability of the seal.

[0100] The first sealing member 7 includes a sliding sealing portion 71 and a shaft sealing portion 72 disposed inside the sliding sealing portion 71. The sliding sealing portion 71 is slidably sealed with the fixed seat 6, and the shaft sealing portion 72 wraps the lock shaft 21. That is, the sliding sealing portion 71 is sandwiched between the fixed seat 6 and the adjustment seat 5, and the side of the sliding sealing portion 71 away from the fixed seat 6 is convexly provided with the above-mentioned insertion convex ring 73.

[0101] The thickness of the shaft sealing portion 72 gradually decreases in the direction away from the sliding sealing portion 71, so as to enhance the deformation ability of the inner end of the shaft sealing portion 72 while ensuring that the overall thickness of the first seal 7 meets the structural strength of the first seal 7. Therefore, when the shaft sealing portion 72 wraps the lock shaft 21, the friction between the two is reduced, thereby avoiding the setting of the shaft sealing portion 72 interfering with the rotation of the lock shaft 21.

[0102] In this embodiment, the sliding sealing portion 71 is an annular structure, that is, the first sealing member 7 is an annular structure as a whole. In other embodiments, the length of the first sealing member 7 in the front-to-back direction is greater than the width of the first sealing member 7 in the left-to-right direction, thereby ensuring the sealing effect of the first sealing member 7 while reducing the size of the first sealing member 7 in the left-to-right direction and reducing the cost.

[0103] Furthermore, the stop structure further includes a second seal 8, which is sandwiched between the fixing seat 6 and the opening plane of the mounting hole 50311 to block the gap between the fixing seat 6 and the opening plane of the mounting hole 50311, thereby further preventing the airflow from entering the mounting cavity through the gap, thereby improving the stopping effect of the stop structure. Specifically, the second seal 8 is sandwiched between the bottom structure 5031 and the fixing seat 6.

[0104] In other embodiments, the stopping structure may not include the second sealing member 8, and the effect of stopping the airflow from passing through the fitting gap between the mounting seat 3 and the opening plane of the mounting hole 50311 is achieved by the tight fit between the mounting seat 3 and the opening plane of the mounting hole 50311.

[0105] In order to better ensure the installation stability of the second seal 8, one of the fixed seat 6 and the second seal 8 is provided with a positioning convex ring portion 82, and the other is provided with a positioning groove 62, and the positioning convex ring portion 82 is inserted into the positioning groove 62 to achieve the installation and positioning of the second seal 8 on the fixed seat 6, and ensure the installation position reliability of the second seal 8 and the fixed seat 6. In this embodiment, the second seal 8 is provided with a positioning convex ring portion 82, and the fixed seat 6 is provided with a positioning groove 62.

[0106] That is, the second sealing member 8 includes an annular sealing main portion 81 , which is sandwiched between the bottom structure 5031 and the fixing seat 6 , and a positioning convex ring portion 82 is convexly provided on a side of the sealing main portion 81 away from the bottom structure 5031 .

[0107] In order to ensure the stability of the setting of the adjustment seat 5 after adjustment, the adjustment seat 5 is fastened to the fixed seat 6 by fasteners after adjustment to ensure that the position of the adjustment seat 5 is fixed after adjustment. Specifically, an adjustment fastening hole is provided on the adjustment seat 5, and a fixed fastening hole is provided on the fixed seat 6. At least one of the fixed fastening hole and the adjustment fastening hole is an oblong hole extending in the front-to-back direction. The adjustment fastening hole and the fixed fastening hole are always aligned. The adjustment seat 5 and the fixed seat 6 are connected by fasteners provided in the adjustment fastening hole and the fixed fastening hole.

[0108] Furthermore, the fixing fastening hole is a circular hole, a fixing hole is provided on the bottom structure 5031, the fixing hole is directly opposite to the fixing fastening hole, and the adjusting fastening hole is an oblong hole. The fasteners are fastening bolts and locking nuts, the fastening bolts pass through the fixing hole, the fixing fastening hole and the adjusting fastening hole in sequence from bottom to top, and the locking nut is screwed on the end of the fastening bolt and pressed against the upper side of the adjusting seat 5. One fastener is provided on each of the left and right sides of the first sealing member 7 to ensure the installation stability and reliability between the adjusting seat 5 and the fixing seat 6.

[0109] Embodiment 3

[0110] This embodiment provides a cooking device, and the cooking device provided in this embodiment is basically the same as that in the second embodiment, with only differences in the arrangement of the adjustment seat 5 and the first sealing member 7. This embodiment will not repeat the same structure as that in the second embodiment.

[0111] like Fig.10 and Fig.11 As shown, in this embodiment, a convex column portion 53 is protruded on one side of the adjusting seat 5 facing the fixed seat 6, the convex column portion 53 is slidably inserted in the shaft through hole 61, the lock shaft 21 rotates through the convex column portion 53, the first sealing member 7 is sleeved on the outer side of the convex column portion 53 and is located between the adjusting seat 5 and the fixed seat 6, and the adjusting seat 5 and the fixed seat 6 are slidably sealed by the first sealing member 7.

[0112] That is, in this embodiment, the first sealing member 7 does not contact the lock shaft 21 , and the first sealing member 7 blocks the gap between the adjustment seat 5 and the fixing seat 6 .

[0113] By providing the convex column portion 53 , the probability of the adjustment seat 5 being separated from the fixed seat 6 during the sliding process of the adjustment seat 5 relative to the fixed seat 6 can be reduced, thereby improving the stability and reliability of the adjustment of the adjustment seat 5 and improving the adjustment efficiency.

[0114] Furthermore, the first seal 7 is interference-fitted on the boss portion 53 , thereby preventing the airflow at the shaft through-hole 61 from entering between the first seal 7 and the boss portion 53 , thereby ensuring the stopping and sealing effect of the first seal 7 and improving the setting stability of the first seal 7 .

[0115] The adjustment seat 5 includes a main seat body 51, and a convex column portion 53 is protruded downwardly from the main seat body 51. The main seat body 51 also has a mounting ring portion 52 protruding in the direction toward the fixed seat 6, and the mounting ring portion 52 and the convex column portion 53 are surrounded to form an insertion groove 55. The first sealing member 7 includes a sliding sealing portion 71 and an insertion convex ring 73 protruding from one side of the sliding sealing portion 71, and the insertion convex ring 73 is inserted in the sealing groove 31, and the sliding sealing portion 71 is sandwiched between the fixed seat 6 and the mounting ring portion 52.

[0116] Furthermore, the first seal 7 also includes an outer ring portion 74 connected to the outer side of the sliding seal portion 71 , the outer ring portion 74 is spaced apart from the insertion convex ring 73 , and the outer ring portion 74 is sleeved on the outer side of the mounting ring portion 52 to enhance the overall structural strength of the first seal 7 .

[0117] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention.
