[0041] like Figures 1 to 8 As shown, Figure 1The direction A in the middle represents the axial direction of the exhaust hole 12, which is also the height direction of the shell 10. The utility model proposes a cooking device 100, including a shell 10 and a filter assembly 20. The interior of the shell 10 defines a cooking cavity 11 having the exhaust hole 12. The cooking cavity 11 is connected to the shell 10 through the exhaust hole 12. The cooking cavity 11 is connected to the shell 10 through the exhaust hole 12. The filter assembly 20 is installed in the exhaust hole 12 in a detachable manner. The filter assembly 20 can rotate with the axis of the exhaust hole 12 as the rotation axis, and the filter assembly 20 has a first position and a second position on the rotation path. The filter assembly 20 is connected to the shell 10 in the first position. In the second position, the filter assembly 20 can move toward the cooking cavity 11 along the axial direction of the exhaust hole 12 to separate from the shell 10.

[0042] It is understandable that the cooking device 100 can be a device that heats food for cooking, such as an oven or a pizza oven. The cooking device 100 has a cubic shell 10, and the interior of the shell 10 defines a cooking cavity 11, and the cooking cavity 11 has an opening for food to enter and exit. A heating device such as a heating tube can be provided in the cooking cavity 11 to heat the food, and high-temperature gas will be generated during the heating process. An exhaust hole 12 can be provided on the top or side of the shell 10 to discharge the gas in the heating cavity. In order to reduce emissions such as oil smoke, a filter assembly 20 can be provided in the exhaust hole 12 to filter the exhaust gas. The filter assembly 20 has a filter element 21, and the filter element 21 can refer to existing filter materials. The utility model detachably installs the filter assembly 20 in the exhaust hole 12 by plugging and fixing it with rotation, so that the filter assembly 20 can be easily disassembled and cleaned. Specifically, the main body of the filter assembly 20 can be cylindrical and fit into the exhaust hole 12. A support ear 22 can be provided at the side end of the main body of the filter assembly 20, and a support shoulder 13 can be provided on the wall of the exhaust hole 12. After the filter assembly 20 is inserted into the exhaust hole 12, the filter assembly 20 is rotated to rotate the support ear 22 onto the support shoulder 13, so that the filter assembly 20 is suspended from the support shoulder 13, thereby achieving detachable installation of the filter assembly 20 in the exhaust hole 12 of the housing 10. A groove can also be provided at the side end of the filter assembly 20, and a protrusion can be provided on the wall of the exhaust hole 12. The groove can be T-shaped or L-shaped, with an opening at the end. The protrusion enters from the opening and moves along the groove. The filter assembly 20 is then rotated so that the protrusion rotates to the corner of the groove. The protrusion supports the filter assembly 20 through the groove wall, thereby achieving detachable installation of the filter assembly 20 in the exhaust hole 12 of the housing 10.

[0043] The cooking device 100 disclosed herein comprises a cooking cavity 11 for cooking ingredients. The cooking cavity 11 has an exhaust hole 12. A filter assembly 20 is removably mounted within the exhaust hole 12 to filter exhaust gases. To install the filter assembly 20, it is moved to a first position by plugging it in and then rotated to a second position along the circumference of the exhaust hole 12 to secure it to the housing 10. To remove the filter assembly 20, it is rotated from the second position to the first position and then pulled out along the axial direction of the exhaust hole 12, making it easier for the user to remove and clean the filter assembly 20.

[0044] In some embodiments of the present invention, a support shoulder 13 is formed by a protrusion on a portion of the hole wall of the exhaust hole 12. The support shoulder 13 is provided with a plurality of notches 132 arranged at intervals along the circumference of the exhaust hole 12. The filter assembly 20 includes a filter element 21 and a plurality of ears 22. The ears 22 are arranged on the filter element 21, and the plurality of ears 22 are arranged at intervals along the circumference of the exhaust hole 12. The filter assembly 20 can be rotated to a first position so that the filter element 21 is suspended on the support shoulder 13 through the ears 22. The filter assembly 20 can also be rotated to a second position so that the ears 22 can move from the notch 132 along the axial direction of the exhaust hole 12 to separate from the shell 10.

[0045] It is understood that the support shoulder 13 can be formed by a protrusion of a portion of the hole wall at one end of the exhaust hole 12 near the cooking cavity 11. The support shoulder 13 can be arranged in a ring shape or extend along the circumference of the exhaust hole 12. A plurality of notches 132 can be provided on the inner circumference of the support shoulder 13 for the support lugs 22 to pass through when they move axially along the exhaust hole 12. The size of the notches 132 is larger than that of the support lugs 22. The filter element 21 is the main body of the filter assembly 20. The shape of the filter element 21 can be adapted to the exhaust hole 12, for example, it can be cylindrical or flat. The support lugs 22 can be provided on the circumference of the filter element 21 and spaced apart along the circumference of the exhaust hole 12. The number of the support lugs 22 can be the same as the number of the notches 132. To install the filter assembly 20, the filter element 21 can be inserted from the cooking cavity 11 into the exhaust hole 12, aligning the lug 22 with the notch 132 so that the lug 22 is in the second position. Continuing the insertion movement will move the lug 22 between the support shoulder 13 and the outlet of the exhaust hole 12. The filter assembly 20 can then be rotated to move the lug 22 to the first position, where the filter assembly 20 is suspended from the support shoulder 13 by the lug 22. To remove the filter assembly 20, the filter assembly 20 can be rotated to move the lug 22 from the second position to the first position, aligning it with the notch 132. At this point, the support shoulder 13 no longer supports the lug 22, and the filter assembly 20 can be pulled out along the axial direction of the exhaust hole 12 to complete removal.

[0046] In some embodiments of the present invention, a first limiting portion 221 is provided on the side of the support ear 22 facing the support shoulder 13, and a second limiting portion 131 is provided on the side of the support shoulder 13 facing the support ear 22. The filter assembly 20 is in the first position, the first limiting portion 221 is connected to the second limiting portion 131, and the first limiting portion 221 limits the circumferential movement of the second limiting portion 131 along the exhaust hole 12.

[0047] It is understandable that a first limiting portion 221 may be provided on the lower surface of the support ear 22, and correspondingly, a second limiting portion 131 may be provided on the supporting surface of the support shoulder 13. The first limiting portion 221 and the second limiting portion 131 may be a combination of grooves or protrusions, or a combination of convex points and concave pits. When the support ear 22 follows the rotation of the filter assembly 20 and moves circumferentially along the exhaust hole 12, the first limiting portion 221 on the support ear 22 may rotate to the second limiting portion 131. The second limiting portion 131 cooperates with the first limiting portion 221 to limit the rotation of the support ear 22. This, in turn, cooperates with the support shoulder 13 to limit the axial movement of the support ear 22 along the exhaust hole 12, thereby limiting the position of the filter assembly 20 and improving the reliability of the installation of the filter assembly 20.

[0048] In some embodiments of the present invention, the first limiting portion 221 includes a first protrusion, the second limiting portion 131 includes a first groove, the first protrusion and the first groove both extend along the radial direction of the exhaust hole 12, and the filter assembly 20 is in the first position so that the first protrusion is located in the first groove;

[0049] Alternatively, the first limiting portion 221 includes a first groove, the second limiting portion 131 includes a first protrusion, the first protrusion and the first groove both extend radially along the exhaust hole 12, and the filter assembly 20 is in the first position so that the first protrusion is located in the first groove.

[0050] It is understandable that the first protrusion may be in the form of an elongated strip extending radially along the exhaust hole 12, and the first groove may be in the form of an elongated slot extending radially along the exhaust hole 12. Taking the example of a first protrusion provided on the support ear 22 and a first groove provided on the support shoulder 13, when the support ear 22 follows the rotation of the filter assembly 20 and moves circumferentially along the exhaust hole 12, the first protrusion on the support ear 22 may rotate to the first groove, and the filter assembly 20 may fall under gravity, and the first protrusion may fall into the first groove. The first protrusion and the first groove cooperate to limit the rotation of the support ear 22, and further cooperate with the support shoulder 13 to limit the axial movement of the support ear 22 along the exhaust hole 12, thereby limiting the position of the filter assembly 20 and improving the reliability of the installation of the filter assembly 20.

[0051] In some embodiments of the present invention, the filter element 21 includes a shell 211 and a filter portion 212. The shell 211 has an annular structure. The lug 22 is arranged on the outer peripheral wall of the shell 211. A flow chamber 2111 is defined in the shell 211. Along the axial direction of the shell 211, both ends of the flow chamber 2111 are open. The filter portion 212 is installed in the flow chamber 2111 and separates the two ends of the flow chamber 2111, or the filter portion 212 is covered at one axial end of the shell 211.

[0052] It is understandable that the shell 211 can be cylindrical or truncated cone-shaped. The shell 211 is hollow and open at both ends to form a flow chamber 2111, an exhaust channel is formed inside the shell 211, and can be used to install the filter unit 212. The filter unit 212 can be a filter screen or a filter material structure, installed at one axial end of the shell 211, or filled in the flow chamber 2111. The lug 22 can be integrally formed on the outer peripheral wall of the shell 211 to improve the structural strength. Specifically, the lug 22 can be formed by bending the part of the axial end of the shell 211 outward, and the contour of the lug 22 is smoothly transitioned. The outer edge of the lug 22 is arc-shaped to reduce damage to the exhaust hole 12. Correspondingly, the contour of the notch 132 on the support shoulder 13 is also smoothly transitioned, and the corners are rounded to reduce stress and protect the filter assembly 20.

[0053] In some embodiments of the present invention, the cooking device 100 also includes an exhaust pipe assembly 30, which is inserted into the exhaust hole 12. The exhaust pipe assembly 30 includes at least one third limiting portion 33 extending radially along the exhaust hole 12. In the first position, along the axial direction of the exhaust hole 12, the support ear 22 is located between the third limiting portion 33 and the support shoulder 13.

[0054] It can be understood that the exhaust pipe assembly 30 is a tubular structure as a whole, and the exhaust pipe assembly 30 is inserted and fixed in the exhaust pipe. The third limiting portion 33 can be set on the side of the inlet end of the exhaust pipe assembly 30 facing the exhaust hole 12, or set on the outer peripheral wall of the exhaust pipe assembly 30. The third limiting portion 33 can be spaced between the support shoulder 13 to form a limiting space. When installing the filter assembly 20, the filter element 21 can be inserted into the exhaust hole 12 from the cooking cavity 11, and the support ear 22 is aligned with the notch 132 so that the support ear 22 is in the second position. Continuing the insertion action can move the support ear 22 into the limiting space. At this time, rotating the filter assembly 20 can rotate the support ear 22 to the first position. The filter assembly 20 is suspended on the support shoulder 13 by the support ear 22 to achieve installation, and the support shoulder 13 and the third limiting portion 33 respectively limit the movement of the support ear 22 toward the axial ends of the exhaust pipe to achieve limitation. When removing the filter assembly 20, the filter assembly 20 can be rotated along the circumference of the limiting space, and the support ear 22 can be rotated from the second position to the first position to align with the notch 132. At this time, the support shoulder 13 no longer supports the support ear 22, and the filter assembly 20 can be pulled out along the axial direction of the exhaust hole 12 to achieve disassembly.

[0055] In some embodiments of the present invention, the exhaust pipe assembly 30 also includes a first exhaust pipe 31 and a second exhaust pipe 32. The first exhaust pipe 31 and the second exhaust pipe 32 are coaxially arranged and connected. The diameter of the first exhaust pipe 31 is larger than the diameter of the second exhaust pipe 32. The first exhaust pipe 31 is connected to the second exhaust pipe 32 through a third limiting portion 33. The first exhaust pipe 31 is installed in the exhaust pipe, and at least part of the second exhaust pipe 32 is arranged in the flow chamber 2111.

[0056] It is understood that the first exhaust pipe 31 is installed in the exhaust hole 12, and the second exhaust pipe 32 has a smaller diameter than the first exhaust pipe 31. This allows for a coaxial connection between the second exhaust pipe 32 and the first exhaust pipe 31, creating a accommodating space between the first and second exhaust pipes 31, 32. This accommodating space is the space within the groove of the limiting space. The connecting portion can be annular or include multiple connecting plates or connecting columns. The outer peripheral wall of the second exhaust pipe 32 is connected to the inner peripheral wall of the first exhaust pipe 31 via the connecting portion. A limiting space is defined between the connecting portion, a portion of the inner wall of the first exhaust pipe 31, a portion of the outer wall of the second exhaust pipe 32, and the support surface of the support shoulder 13. It is noteworthy that a gap exists between the outer peripheral wall of the second exhaust pipe 32 and the inner side of the support shoulder 13 to allow for the rotation of the filter assembly 20. The provision of the limiting space allows the filter assembly 20 to be axially limited when plugged and rotatably installed onto the support shoulder 13, thereby improving the installation reliability of the filter assembly 20.

[0057] In some embodiments of the present invention, the exhaust pipe assembly 30 includes a plurality of third limiting portions 33 arranged in pairs, and the plurality of third limiting portions 33 are arranged at intervals along the circumference of the exhaust pipe. In any pair of third limiting portions 33, the position of one of the third limiting portions 33 in the circumferential direction of the exhaust hole 12 corresponds to one side of the notch 132, and the other third limiting portion 33 is arranged at intervals from the other side of the notch 132 in the circumferential direction of the exhaust hole 12, and the support ear 22 can move between the two third limiting portions 33 of a pair of third limiting portions 33.

[0058] It is understood that the third limiting portion 33 can be in the form of an elongated plate or a column. Its ends are connected to the inner circumferential wall of the first exhaust pipe 31 and the outer circumferential wall of the second exhaust pipe 32, respectively. Multiple pairs of third limiting portions 33 can be provided along the circumference of the exhaust pipe. The specific number of third limiting portions 33 can be twice the number of notches 132, such that each notch 132 is provided with a third limiting portion 33 on both sides, and one of the third limiting portions 33 is spaced apart from the notch 132. When installing the filter assembly 20, the filter element 21 can be inserted into the exhaust hole 12 from the cooking cavity 11, and the ear 22 can be aligned with the notch 132 so that the ear 22 is in the second position. Continuing the insertion action can move the ear 22 into the limited space. At this time, the third limiting portion 33 corresponding to one side of the notch 132 can limit the filter assembly 20 from rotating to the other side. Continuing to rotate the filter assembly 20 can rotate the ear 22 to the first position. The third limiting portion 33 there can prevent the ear 22 from continuing to move. The first limiting portion 221 on the ear 22 can be limited and matched with the second limiting portion 131, thereby locking the position of the ear 22, and then the filter assembly 20 is suspended on the support shoulder 13 through the ear 22 for installation. When removing the filter assembly 20, the filter assembly 20 can be rotated along the circumferential direction of the limiting space, and the ear 22 can be rotated from the second position to the first position to align with the notch 132. At this time, the third limiting portion 33 corresponding to one side of the notch 132 can limit the movement of the ear 22 away from the notch 132, and then the ear 22 falls into the notch 132, and the support shoulder 13 no longer supports the ear 22. The filter assembly 20 can be pulled out along the axial direction of the exhaust hole 12 to achieve disassembly.

[0059] In some embodiments of the present invention, a flange 133 is provided on one side of the support shoulder 13 facing the axis of the exhaust hole 12 . The flange 133 extends away from the cooking cavity 11 , and is partially recessed to form a first groove.

[0060] It is understood that the support shoulder 13 can be formed by the housing 10 extending into the exhaust hole 12 at the inlet end of the exhaust hole 12. The edge of this portion of the housing 10 can be bent to form a flange 133. The flange 133 can enhance the structural strength of the support shoulder 13, and a first groove can be defined in the flange 133. Specifically, the support shoulder 13 can be annular, so that the inner side of the support shoulder 13 defines a mounting hole for inserting the filter assembly 20. The flange 133 can also be annular to increase the thickness of this area, thereby enhancing the strength of the mounting hole. The flange 133 can be configured in an arc shape to reduce wear of the support shoulder 13 on the filter assembly 20.

[0061] In some embodiments of the present invention, the cooking device 100 also includes an exhaust cover assembly 40, at least part of which is installed in the pipe opening of the exhaust pipe assembly 30 at one end facing away from the cooking cavity 11, and the exhaust pipe assembly 30 is connected to the outside world through the exhaust cover assembly 40.

[0062] It can be understood that the exhaust cover assembly 40 can be formed by snapping together a bottom cover 42 and a top cover 41. The top cover 41 and the bottom cover 42 can both be disc-shaped structures. The pit formed by the top cover 41 is docked with the pit formed by the bottom cover 42.
