Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, specifically to a cooking device. Background Technology

[0002] With the development of home appliance technology, cooking equipment that can meet users' diverse and refined cooking needs has emerged, such as cooking equipment that uses one or more cooking methods such as steaming, baking, and frying to cook ingredients. Taking baking as an example, the corresponding cooking equipment can be in the form of a single-cavity / double-cavity oven with baking as the only cooking method, or it can be a combination steam oven or steam oven-fryer that includes baking.

[0003] The cooking principle of roasting is to provide circulating hot air into the inner chamber (the cooking cavity) containing the food, thus cooking it through hot air roasting. The cooking principle of steaming is to provide high-temperature steam into the inner chamber containing the food, thus cooking it through pure steaming. There are also cooking methods that combine steaming and roasting (such as a tender roasting mode).

[0004] Taking an oven (using baking as the cooking method for baking only) as an example, and assuming the food to be cooked is meat such as chicken, goose, or lamb, these foods typically contain oil and moisture. Therefore, during the cooking process (heating to maturity), oily substances such as grease, grease, and grease residue will inevitably splatter, drip, or fall onto the top, side, and bottom walls of the oven cavity (and the inner wall of the door). Accordingly, to ensure the performance of the cooking equipment and the user experience, the oven needs to be cleaned promptly. Currently, high-temperature pyrolysis steam cleaning generally suffers from poor cleaning results and is therefore not widely accepted. Wiping / rinsing cleaning theoretically offers better results; however, due to limitations in implementation, its effectiveness still has room for improvement. Issues include, but are not limited to, cumbersome / inconvenient operation, incomplete cleaning of all / partial areas, and difficulty for users to operate. Utility Model Content

[0005] The present invention aims to solve at least part of the above-mentioned technical problems and / or solve at least part of the above-mentioned technical problems. Specifically, it aims to improve the cleaning effect of cooking equipment and, under this premise, improve the user experience as much as possible.

[0006] In view of this, the present invention provides a cooking device, which includes a housing and an inner liner assembly disposed in the housing. The inner liner assembly includes: a first inner liner; a second inner liner disposed in the first inner liner in a removable manner, the second inner liner forming a cooking chamber; and a drain portion that forms a passage so that liquid in the cooking chamber can be discharged through the passage; wherein the second inner liner includes a base and at least one inner liner unit disposed in the base, at least a portion of the inner liner unit being removable from the base.

[0007] This design allows for external cleaning of the cooking appliance after the inner liner has been removed from the main body. This is expected to improve the cleaning efficiency of the cooking appliance. The method of pulling out the first / second side panels a short distance, adjusting their intermediate position, and then removing them from the cooking appliance in this intermediate position avoids interference with other structures of the cooking appliance or the installation space during removal, thus ensuring the ease of quick disassembly.

[0008] Furthermore, the drainage system allows for the timely removal of liquids from the cooking chamber, ensuring the cleanliness of the cooking equipment.

[0009] In one possible implementation of the above-mentioned cooking equipment, the drain section includes: a first drain structure disposed in the first inner tank; and a second drain structure disposed in the second inner tank; the first drain structure and the second drain structure are capable of forming the passage.

[0010] In one possible implementation of the above-mentioned cooking equipment, the first drain structure is provided with a first docking structure, and the second drain structure is provided with a second docking structure. The first drain structure and the second drain structure can form the passage by means of the cooperation of the first docking structure and the second docking structure to align with each other.

[0011] In one possible implementation of the cooking device described above, the drain section includes a stop structure, by which the first drain structure and the second drain structure can be aligned with each other.

[0012] If viewed along the direction in which the second inner liner is pushed into the first inner liner, the stop structure is located on the downstream side or near the downstream side of the first drainage structure.

[0013] In one possible implementation of the cooking device described above, the base is provided with a second clearance structure at a position corresponding to the drain section.

[0014] In one possible implementation of the above-mentioned cooking equipment, the second inner pot includes a first limiting component that forms a side panel mounting space and / or a back panel mounting space. Accordingly, the at least one inner pot unit includes: a first side panel and a second side panel that can be connected to the side panel mounting space; and / or a second back panel that can be connected to the back panel mounting space.

[0015] In one possible implementation of the above-mentioned cooking equipment, the at least one inner pot unit includes a second bottom plate, and the limiting component includes a first limiting structure and a second limiting structure disposed on the second bottom plate. The first limiting structure and the second limiting structure form the side plate mounting space at positions corresponding to the first side plate and / or the second side plate, and the first limiting structure and the second limiting structure form the back plate mounting space at positions corresponding to the second back plate.

[0016] In one possible implementation of the above-mentioned cooking equipment, the inner pot unit includes multiple sub-parts, at least a portion of which can be removably disposed on the base (e.g., the inner pot unit includes multiple spliced ​​sub-parts; or the inner pot unit includes at least two stacked sub-parts, at least the inner sub-parts can be removably disposed on the base); and / or the base includes a frame, the frame including a first sub-frame and a second sub-frame, the first sub-frame and the second sub-frame constituting the frame in a relatively telescoping manner.

[0018] In one possible implementation of the above-mentioned cooking device, the inner pot unit includes a top plate, and the cooking device includes a first heating element located inside the top plate, wherein the first heating element is at least fixedly disposed on the first inner pot.

[0061] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although this embodiment is described in conjunction with an oven that only includes baking as a cooking method, this is not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can apply the present invention to other application product forms, such as steam ovens, steam-bake-fryers, dual-cavity ovens / steam ovens, etc. Furthermore, in addition to being applicable to cooking equipment that includes baking as a cooking method, the present invention is also applicable to cooking equipment for other cooking methods (such as frying) that require similar cleaning.

[0062] It should be noted that in the description of this utility model, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0063] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0064] Furthermore, to better illustrate this utility model, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this utility model can be implemented even without certain specific details. In some examples, the structural forms of ovens, baking principles / processes / parameters, etc., which are well-known to those skilled in the art, are not described in detail, in order to highlight the main points of this utility model.

[0065] The following will refer to the appendix. Figures 1 to 13 The present invention is described in at least a portion thereof.

[0066] Main reference Figures 1 to 13 In one possible implementation, the oven 100 includes a housing 1 and an inner liner assembly 2 disposed in the housing 1. The inner liner assembly 2 includes a first inner liner 21 and a second inner liner 22 disposed within the first inner liner. The second inner liner forms a cooking chamber. The first inner liner 11 is disposed within the housing 1, and the second inner liner 22 is disposed within the first inner liner 21 in a retractable manner. An operation panel 11 for display and interaction (such as mode selection, parameter setting, etc.) is provided on the front side of the housing 1 near the top.

[0067] In one possible implementation, the second inner liner 22 includes a base 221 and one or more inner liner units disposed on the base, at least a portion of which are removably disposed on the base. As in this example, the base is generally a frame, and the inner liner units include multiple units, specifically a top plate 222, first side plates 223 / second side plates 224 on the left / right sides, a second back plate 225 (which may also be called a fan cover in this example), and a second bottom plate 226. Each inner liner unit is detachably disposed on the frame. Therefore, by removing the top plate, second bottom plate, fan cover, and first / second side plates from the frame, the user can easily perform deep cleaning of each inner liner unit from the outside of the oven using methods such as placing them in a dishwasher, manually cleaning them in a sink, or cleaning specific locations for cleaning the inner liner units.

[0068] For the first / second side panels, after pulling the second inner liner out relative to the first inner liner, they can be removed from the frame by pulling them upwards. However, due to limitations in the pull-out range of the pull-out structure, such as the slide rail assembly, and the oven's installation location (e.g., installed inside a cabinet), removing the first / second side panels from the frame by pulling them upwards may result in interference with the control panel / cabinet, or even prevent them from being pulled out at all. Therefore, in this invention, the method for removing the first / second side panels is improved as follows.

[0069] In the example, the first and second side panels are roughly symmetrical in structure and their removal methods are basically the same. The following explanation uses the first side panel as an example. Alternatively, the removal method can be applied to only one side panel. Furthermore, the removal methods for the first and second side panels can be differentiated.

[0070] In one possible implementation, the inner liner assembly includes a first limiting assembly, which includes a first limiting structure 261 and a second limiting structure 262 disposed on the second base plate 226. The first limiting structure 261 and the second limiting structure 262 respectively form two side plate mounting spaces 2261 at positions corresponding to the first / second side plates, which can cooperate with the first / second side plates. The first limiting structure 261 and the second limiting structure 262 form a back plate mounting space 2262 at positions corresponding to the second back plate 225.

[0071] In this example, the first limiting structure 261 is a flange extending upward from the outer edge of the second base plate 226, and the second limiting structure 262 is a pressing pattern with a roughly L-shaped structure located at the four corners of the second base plate. For example, the cross-section of the pressing pattern is roughly an isosceles trapezoid.

[0072] For example, when the first side panel 223 and the second side panel 224 need to be removed from the frame, the following removal method can be used:

[0073] S11. First, pull the first / second side panel upwards by a preset distance (e.g., a small distance of ≤5cm, for example, about 1cm) so that the bottom of the first / second side panel is freed from the constraint of the side panel mounting space 2261. With this action, the upper part of the first / second side panel is also freed from its constraint with the frame. However, if it is pulled upwards further, it may interfere with the outer frame of the first inner liner, the control panel of the housing, or other structures. Therefore, the following operation method can be used instead.

[0074] S12. Adjust the first / second side plate to the intermediate posture of the side plate, including rotation. In this example, the first / second side plate and the second base plate are adjusted to the intermediate posture in the plane where the second base plate is located or in a plane parallel to the second base plate. Other reasonable postures are also possible, such as an inclined posture with a height difference between different parts.

[0075] For example, after translating the first / second side panel along the width direction (left-right direction) of the inner liner assembly by a preset distance (e.g., ≤5cm), rotate it by a preset angle (such as rotation along the translated inner side or rotation approximately along the axis corresponding to the inner side, allowing the inner side itself to have a certain displacement), so as to at least ensure that when the first / second side panel is pulled upward in the vertical direction in this posture, it will not interfere with the structure of the oven or the structure of the installation space where the oven is located (e.g., cabinets).

[0076] In this example, the second base plate is roughly rectangular, and the side plates are positioned so that the first / second side plates are approximately diagonally opposite the second base plate (e.g., rotated by about 45-60°). This position can be flexibly adjusted while ensuring no interference. That is, when the first / second side plates are in the center of the side plate orientation, the potential interference structures do not overlap with the projections of the first / second side plates in the horizontal plane.

[0077] Obviously, the description of translating first and then rotating is just an example. Those skilled in the art can determine the specific operation method according to actual needs, such as adjusting to the middle posture of the side plate directly through any other feasible trajectory (such as the trajectory can be relatively free or limited).

[0078] To ensure repeatability of disassembly, appropriate limiting structures can be used to determine the specific position of the side panel in its intermediate posture and the specific operation method to reach it. For example, a strip-shaped limiting structure can guide the user to first translate the first / second side panel after pulling it upwards in the first step. Additionally, a pair of limiting structures at the diagonal points can be used to determine the specific position corresponding to the intermediate posture.

[0079] S13. Pull the first / second side panel, which is in the middle position of the side panel, out of the oven in a generally vertically upward manner.

[0080] In this example, the first and second side panels are removed using roughly the same method. Therefore, the removal method applicable to both the first and second side panels will be described together. However, in practice, the removal of the first and second side panels should be sequential. Furthermore, the removal methods for the first and second side panels may also differ.

[0081] For example, when the second back panel 225 needs to be removed from the frame, the following removal method can be used:

[0082] S21. First, the second back plate 225 is pivoted relative to the substrate to generate a certain amount of rotation (such as a rotation angle between 5-15°, for example, 5°).

[0083] In this example, the profile has a pre-reserved structure 2621 on the side near the second back plate, such as a slope or arc, allowing rotation. In this example, the profile's cross-section is approximately an isosceles trapezoid; therefore, the pre-reserved structure 2621 is the slope of the profile corresponding to the outer side of the isosceles trapezoid. Thus, the back plate mounting space 2262 formed by the slope and the flange is a pivoting space that allows the second back plate 225 to rotate by a certain amount. Correspondingly, a certain amount of rotation can be generated by applying a certain external force to the second back plate. For example, the bottom side of the second back plate 225 has a stepped surface 2251, the vertical portion of which can be inserted into the pivoting space, and the horizontal portion of which can sit on the upper surface of the flange.

[0084] S22. Based on this, the pivot connection between the second backplate and the base can be released by applying an outward pulling force, thereby disassembling it from the frame. Compared to the assembled state, the rotation causes the highest position of the second backplate to be lowered, thus placing it in a position where it is easier to pull the second backplate out to the external space, thereby increasing the feasibility of quick-release operation.

[0085] In one possible implementation, a pivoting limiting structure is provided on the second inner liner to adapt to the pivoting movement of the second back panel. When rotated to the position corresponding to the pivoting limiting structure, the user can smoothly pull out the second back panel and ensure consistent operation during pivoting removal. In this example, the pivoting limiting structure is roughly a pair of baffles respectively disposed on the inner side of a pair of first sliding structures in the middle of the second / second side panel. Obviously, those skilled in the art can determine the structural form, number, and placement of the pivoting limiting structure according to actual needs. For example, it can also be a point / block structure, a strip structure, etc., and can also be disposed on the base, the first / second side panel (in this case, the first / second side panel must be removed after the second back panel is removed), etc.

[0086] In this way, the second back panel can be removed by first flipping it outwards and then pulling it out diagonally upwards.

[0087] Obviously, the combination of flanging and pressing is only an exemplary description of forming the aforementioned side panel mounting space and back panel mounting space. Those skilled in the art can determine the structural form and specific formation method of the side panel / back panel mounting space according to actual needs, such as including but not limited to: the side panel / back panel mounting space is formed by two sets of structures, such as the structural forms of the two sets of structures (two first limiting components) can be the same or different, the two sets of structures can be set separately, connected to each other, or integrally formed; the first / second limiting structure can be a strip structure, multiple point (block) structures, etc.; the second limiting structure forming the back panel mounting space (closer to the side that mates with the second back panel) can be an elastic structure that allows deformation (such as a thin sheet structure, locally elastic, etc.) or a structure with an elastic structure; the first / second side panel and the corresponding side panel mounting space can be tightly fitted or have a certain margin of fit; a buffer structure can be set at the position of the second base plate corresponding to the side panel / back panel mounting space to ensure stability during disassembly and assembly. For example, taking the L-shaped pressing structure as the second limiting structure, the cross section corresponding to the back panel mounting space can still be an isosceles trapezoid or a right trapezoid with the inner side being the hypotenuse, etc., and the cross section corresponding to the side panel mounting space can be a rectangle or a right trapezoid with the inner side being the vertical side, etc.

[0088] Obviously, the above-described methods for removing the first / second side panels and the second back panel from the substrate are merely exemplary descriptions. Those skilled in the art can flexibly select the method for removing the inner liner unit from the substrate, as well as the corresponding method / direction / specific operation, based on actual needs. For example, one or more of the following methods can be used to remove the inner liner unit from the frame: pulling upwards, pulling to the side, tilting, or flipping. This may include, but is not limited to: the removal methods for the first / second side panels being the same or different; the second back panel being removed using a combination of horizontal left / right flipping and oblique outward pulling; and other inner liner units such as the top panel and the second bottom panel being removed using similar methods (such as those involving rotation).

[0089] In one possible implementation, the frame has a first clearance structure 2211 located above (on the upper side) near the first / second side panel. In this example, the first clearance structure is a strip-shaped recessed molding, allowing the user to pull the first / second side panel upwards by inserting their hand into the position corresponding to the recessed molding. Obviously, those skilled in the art can determine the form, number, and specific location of the first clearance structure according to actual needs; for example, the first clearance structure could be an insertable hole.

[0090] Obviously, the above structure is merely an exemplary description of the second inner liner. Those skilled in the art can flexibly adjust the structural form and number of the base / inner liner units according to actual needs. For example, it may include, but is not limited to:

[0091] (1) The base may include only the frame, or it may include one or more intermediate structures (such as plate structure, strip structure, block structure, etc.) that are fixedly set on or integrally set on the frame. For example, a sliding / pivoting structure (a structure that can be rotated) or a carrier for installing it may be added to the frame (such as a plate structure, strip structure, block structure, etc.).

[0092] (2) One or more of the top plate, the second bottom plate, the second back plate, and the first / second side plate are fixedly set on or integrally formed on the frame. In this case, this part can also be understood as the base.

[0093] (3) One or more of the top plate, second bottom plate, second back plate, and first / second side plate may include multiple sub-parts. Some of these sub-parts may be fixedly installed or integrally formed on the frame. In this case, sub-parts that are not detached from the frame can also be considered as the base. For example, multiple sub-parts of the inner liner unit can be joined (e.g., directly butt-jointed, joined using a carrier (plate structure, support frame, etc.)) or stacked (e.g., partially overlapping / fully overlapping, stacking of two or more layers) to form the corresponding inner liner unit. Taking stacking as an example, the inner layer can be disassembled and washed.

[0094] It should be noted that, taking the intermediate structure in (1) as an example, in contrast to the removable method, the fixed setting mentioned in (1)-(3) can be understood as follows: since an irreversible fixed connection method such as welding is used, the intermediate structure cannot be disassembled from the frame; for the cleaning function of the oven to be realized by this utility model, it is not necessary to disassemble the intermediate structure; due to the limitations of installation position, matching method, complexity and other factors, disassembly during the cleaning stage is not possible; since disassembly is too complicated and has obvious shortcomings (such as the possibility of affecting the reliability of the oven (such as the possibility of damaging the mechanical connection / electrical connection / other functional components of the oven), and the existence of safety hazards (such as the operation posture is likely to cause injury to the user), the corresponding disassembly operation is not allowed. For example, the disassembly operation can be blocked by adding corresponding limit / stop structure, marking (such as non-removable pattern marking), and interactive logic (such as issuing reminder information).

[0095] (4) The frame is an assembly of multiple sub-frames, which together form the base when assembled. When cleaning the inner liner assembly is required, the sub-frames can move relative to each other to facilitate the removal of the inner liner unit. For example:

[0096] (41) The frame includes a first sub-frame (similar to the current frame) and a second sub-frame (an auxiliary frame located inside the first sub-frame), the second sub-frame being extendable and retractable relative to the first sub-frame in the front-rear direction. In this case, the second sub-frame can be completely accommodated within the first sub-frame. Based on this configuration, when cleaning the inner liner assembly is required, the second sub-frame can be moved forward relative to the first sub-frame, thus allowing the operation position for removing the second back panel from the frame to be moved forward, thereby avoiding interference with positions such as the control panel of an oven.

[0097] (42) The frame includes a first sub-frame (corresponding to the front half of the current frame) and a second sub-frame (corresponding to the rear half of the current frame) that are retractably connected in the front-rear direction. In this case, the two sub-frames can be spliced ​​together to form the frame. Based on this configuration, when the inner liner assembly needs to be cleaned, the operating position of the rear panel can be shifted by moving the second sub-frame forward relative to the first sub-frame. (In this case, as the second sub-frame moves forward, the inner liner unit is disassembled (e.g., the inner liner unit is sandwiched between the two sub-frames) or the operating position for removing the inner liner unit is shifted forward (e.g., the inner liner unit is positioned in the second sub-frame).

[0098] In one possible implementation, the inner liner assembly includes a sliding portion 23, which includes a first sliding structure 231 disposed in the first inner liner and a second sliding structure 232 disposed in the second inner liner. In this example, the first sliding structure 231 includes a pair of slide rails disposed at approximately the center of the first / second side panels. Correspondingly, another pair of slide rails serving as the second sliding structure 232 are disposed at corresponding positions on the two side panels of the first inner liner. Obviously, those skilled in the art can determine the structural form, number, and placement of the first / second sliding structures according to actual needs. For example, the first / second sliding structures can be located at the junction of the bottom and sides of the inner liner assembly; any type of slide rail can be selected, or other types of sliding connection pairs can be chosen. For example, in addition to providing slide rails at the center of the first / second side panels, a pulley 233 can also be added to the bottom of the second inner liner to ensure convenience and stability during the sliding process.

[0099] Taking the slide rail assembly as an example, once the slide rail assembly is installed, the range of sliding of the second inner liner relative to the first inner liner can be determined. Alternatively, a sliding limiting structure, such as a limiting block, can be added to the sliding part to define the start and end positions of the sliding connection. However, since the starting point of this invention is to propose a quick-release cleaning solution, the specific structural form of the sliding part itself is not particularly limited. In other words, the structural form of the limiting structure, whether or not to set a sliding limiting structure on the sliding part (and how to set it if so), etc., can be flexibly selected according to actual needs.

[0100] In one possible implementation, a guide structure 24 is provided on the top plate 222, and the guide assembly is located near the top of the second inner liner. In this example, the guide structure includes a first guide structure 241 and a second guide structure 242 respectively located on the top plate 222 corresponding to the positions of the first and second side plates. In this example, the first and second guide structures are two bends formed on both sides of the top plate, so that in the assembled state, the top plate covers the corresponding positions of the frame and the first / second side plates from above through the two bends on both sides. Taking the connection between the base 221, the top plate 222, and the first side plate 223 as an example, in this example, a base connecting structure 2213 is provided on the frame serving as the base 221, and a side plate connecting structure 2231 that can cooperate with the base connecting structure 2213 is provided above the first side plate 223. In this way, the first side plate 223 can be connected to each other by means of the cooperation between the base connecting structure 2213 and the side plate connecting structure 2231. In this example, the base connection structure 2213 consists of two parallel flanges extending inward from the inside of the frame. The side panel connection structure 2231 is roughly a bend, with the lateral portion of the bend resting on the upper surface of the upper flange and the vertical portion of the bend adhering to the outer surface of the frame. As mentioned earlier, a recessed pressure-form, serving as the first clearance structure, is positioned on the outer surface of the frame corresponding to the vertical portion of the bend. This allows the user to reach their hand into the inner side of the vertical portion of the bend and grip the first side panel. In this case, the side panel connection structure 2231 can directly serve as a handheld end. Alternatively, a handheld end, such as a hole, can be directly machined into the first / second side panel. In this case, the structural form and position of the first clearance structure can be adjusted, or the first clearance space can be omitted.

[0101] Obviously, the above-described structural forms of the base connection structure and side plate connection structure, as well as the corresponding fitting method between the frame and the first side plate, are merely exemplary descriptions. Those skilled in the art can determine the fitting method and implement the corresponding structure according to actual needs, such as replacing a pair of flanges with mounting protrusions or inserting the bent vertical parts into the frame. Based on this, the guide structure on the top plate covers the upper side of the assembly of the base and the first / second side plates. In this way, if there is steam condensation at the top of the oven, liquid can be guided along the molding to the bottom of the second inner liner, thus preventing dripping onto the food in the cooking cavity. Furthermore, this design prevents the frame from rusting due to water ingress at this location. Since the connection is bidirectional, this design also prevents oil stains and steam from the cooking cavity from reaching the inner wall of the first inner liner via this location. Especially in situations where the first inner liner is located near the rear, it may be difficult to detect, and the lack of timely cleaning could affect the oven's performance. Obviously, the structural form, size, and specific wrapping method of the bend can be flexibly selected according to actual needs. For example, the structural form of the bend can be (roughly) an L-shaped structure, an arc-shaped structure, etc. The vertical part of the L-shaped structure can be adjusted to a slope, and a transition section such as an arc-shaped structure can be set between the horizontal and vertical parts of the L-shaped structure. Taking a roughly L-shaped bend as an example, the dimensions of the horizontal and vertical parts can be flexibly adjusted according to actual needs. The first / second guide structure can tightly wrap around the frame and the top position of the first / second side panels, or wrap around them with gaps. Furthermore, the number and arrangement of guide structures can also be flexibly adjusted according to actual needs, such as setting guide structures on the rear side as well.

[0102] In one possible implementation, a water-collecting structure 25 is provided on the top plate 222. When steam condensation occurs at the top of the oven, the resulting liquid can be collected in the water-collecting structure. Exemplarily, a water-collecting structure extends in the front-rear direction near the aforementioned first / second guide structures. In this example, the cross-section of the water-collecting structure is approximately V-shaped, with one sidewall extending vertically and the other sidewall inclined to collect liquid. This allows the liquid to be collected within the water-collecting structure. This ensures the cleanliness of the oven during use (no liquid leakage), and the collected liquid can evaporate naturally at the top. Exemplarily, the lateral portion of the bend can also be configured as a downward-sloping structure from the inside out, so that the liquid collected within the water-collecting structure can be promptly discharged to the bottom of the inner liner assembly. In this example, the bend / water-collecting structure is an integrally formed pressed structure with the top plate.

[0103] In one possible implementation, the second inner liner includes a second limiting component, which is mainly used to limit the top plate 222 in the front-back direction when assembled, thereby preventing the top plate from shifting in the front-back direction when assembled. The second limiting component includes a third limiting structure 263. In this example, the third limiting structure is provided on both the first side plate 223 and the second side plate 224. The third limiting structure is a protrusion, and protrusions are respectively provided on the inner sides of the first and second side plates near the rear. Correspondingly, a fourth limiting structure 264 is provided on the inner side of the top plate, capable of abutting against the protrusions in the front-back direction. In this example, the rear end of the aforementioned water-gathering structure has a surface capable of abutting against the protrusions. Thus, the integrated water-gathering structure and the fourth limiting structure ensure the oven's performance. A sealing structure 27, such as a sealing ring, is typically also provided at the front end of the frame. Thus, the combination of the sealing ring and the top plate limiting component ensures the stability of the top plate in the assembled state. Obviously, the structural form, number, and setting position of the third / fourth limiting structure can be flexibly selected according to actual needs. For example, the third / fourth limiting structure can also be a baffle, flange, limiting block, etc. The third limiting structure can cooperate with the fourth limiting structure, or it can directly cooperate with existing structures / positions such as the rear end face of the top plate. The third limiting structure can also be set on one of the first side plate and the second side plate, or it can be set on the frame. In addition, the third limiting structures set on the first side plate and the second side plate can be the same or different.

[0104] In one possible implementation, since the baking cooking method is related to the temperature and flow rate of the hot airflow as the cooking medium, a first heating element 28, such as a heating tube, can be provided on the inner liner assembly at positions such as the top / side / bottom inner side. This allows for primary or auxiliary / supplementary heating of the cooking medium within the cooking chamber when needed. For example, if the first heating element 28 is located on the top inner side of the inner liner assembly 1, and there is a reserved space above the top of the second back plate 225, the first heating element 28 can be installed onto the first back plate of the first inner liner 11 via this reserved space. To ensure the stability of the first heating element in its installed state (e.g., to avoid problems such as shaking of the first heating element during use when only the rear end is fixed), the first heating element is also simultaneously fixed to the top plate 222 of the second inner liner 22. For example, a first mounting structure, such as a bracket, mounting strip / shaft, mounting plate, or bracket / support with mounting grooves / holes, can be provided on the top plate. The first heating element is fixed to the inner side of the top plate by means of a first connecting structure, such as a mounting clip or mounting buckle, in cooperation with the first mounting structure. In this situation, where it is necessary to remove the top plate from the frame, the constraint between the top plate and the first heating element needs to be released.

[0105] As an alternative, a second mounting structure, such as a bracket, mounting strip / shaft, mounting plate, or bracket / support with mounting grooves / holes, can be added to the first inner liner. The first heating element can be fixed to the first inner liner via a second connecting member, such as a mounting clip or mounting buckle, in cooperation with the second mounting structure. The first heating element can be fixed solely to the second mounting structure (the second mounting structure is fixed to the first inner liner, and the first heating element is fixed to the second mounting structure), or it can be fixed to both the first inner liner and the second mounting structure simultaneously (the first heating element is directly fixed to the first inner liner on one hand, and indirectly fixed to the first inner liner on the other hand via the second mounting structure). In this case, when the top plate needs to be disassembled for cleaning, there is no need to release the constraint between the top plate and the first heating element, thus simplifying the cleaning process. Furthermore, if the first heating element is only suspended within the first inner liner, there is also no need to release the constraint between the top plate and the first heating element when the top plate needs to be disassembled for cleaning.

[0106] In one possible implementation, the inner liner assembly includes a drain section 29, which includes a first drain structure 291 disposed on the first inner liner 21 and a second drain structure 292 disposed on the second inner liner 22. The first drain structure 291 communicates with the second drain structure 292, thus forming a passage for liquid drainage. The second drain structure 292 communicates with the interior of the cooking chamber. For example, the first drain structure can be connected to a collection structure such as a wastewater box via pipes or valves to collect accumulated water within the cooking chamber, or it can be directly connected to the external space to drain liquid from the cooking chamber to the outside of the oven. The drain section ensures the cleanliness of the oven during daily operation. During non-removal cleaning processes such as high-temperature washing, liquid can be drained promptly. During removal cleaning processes, the second bottom plate can be cleaned directly without removing it.

[0107] In one possible implementation, the drain section 29 is located at the bottom of the inner liner assembly. A first drain structure 291 is disposed on the first bottom plate 211 of the first inner liner 21, and a second drain structure 292 is disposed on the second bottom plate 226 of the second inner liner 22. The first drain structure 291 and the second drain structure 292, when assembled, form the aforementioned passageway allowing liquid discharge. Alternatively, the drain section 29 may be located on the side near the bottom of the inner liner assembly, in addition to being located at the bottom.

[0108] In one possible implementation, the first drainage structure 291 is a first pipe segment extending upward from the first base plate 211, and the second drainage structure 292 is a second pipe segment extending downward from the second base plate 226; the first and second pipe segments can form a passage by aligning with each other. Alternatively, in addition to alignment, the passage can be formed by connecting with each other using structures such as corrugated pipes. The lowest point of the second pipe segment should not be higher than the lowest position of the frame of the second inner liner (such as the lowest point of the lower crossbeam) to prevent interference between the second pipe segment and the bottom edge of the first inner liner when the second inner liner is removed from the first inner liner.

[0109] In one possible implementation, the first pipe segment and the second pipe are respectively provided with a first mating structure 2911 and a second mating structure 2921 that mate with each other at their ends near each other. As in this example, both the first mating structure 2911 and the second mating structure 2921 are formed on the first pipe segment and the second pipe segment from the inside out. Figure 3 The inclined plane (sloping downwards from right to left) can be understood as the intersection of an inclined plane and the pipe wall, or the end formed after cutting the first / second pipe segment with an inclined plane. This provides guidance during the extraction or insertion of the second inner liner, provided the passage can be reliably formed and the pulling is interference-free, thus improving the smoothness of the pulling operation. Obviously, the pair of inclined planes is only an exemplary description of the first / second mating structure. Those skilled in the art can flexibly choose the structural form and corresponding mating method of the first / second mating structure according to actual needs, such as curved surfaces or simple planes.

[0110] In this example, both the first base plate 211 and the second base plate 226 are water-collecting structures that are high around the edges and low in the middle, and the first / second pipe section is located at approximately the middle of the first / second base plate.

[0111] In one possible implementation, the drain section 29 includes a stop structure 293, which is mainly used to ensure the reliable matching of the first drain structure 291 and the second drain structure 291. The stop structure may include a pair of structures respectively disposed on the first / second inner tank, or a structure disposed on one of them (which cooperates with an existing structure on the other). For example, the stop structure 293 may be disposed on the first drain structure 291 (cooperating with the second drain structure 291 itself or another structure disposed thereon) or on other structures of the first inner tank 11 (such as cooperating with the second inner tank / second drain structure itself or another structure disposed thereon). In this example, the stop structure 293 is a baffle disposed on the rear side of the first pipe section. Thus, during the process of pushing the second inner tank into the first inner tank, the baffle stops the second pipe section, ensuring accurate docking of the (first and second) pipe sections. Furthermore, without affecting the pulling motion of the second inner tank, a sealing structure can be added to ensure the sealing performance of the (first and second) pipe sections in the docked state.

[0112] In one possible implementation, the frame is provided with a second clearance structure 2212 at a position corresponding to the rear and lower side (rear lower crossbeam). In this example, the second clearance structure is a trapezoidal groove to prevent interference between the frame and the first drainage structure of the first inner liner during the process of pulling the second inner liner out from the first inner liner. Obviously, those skilled in the art can determine the form, number, and specific location of the second clearance structure according to actual needs; for example, the second clearance structure can be a U-shaped groove, etc.

[0113] In one possible implementation, the oven's cooking chamber is provided with a shelf 31 (such as a grill rack), on which food to be cooked can be placed directly or placed on a container (such as a plate) placed on the shelf. One or more shelves can be provided within the cooking chamber, or the shelves can be positioned in one or more locations within the cooking chamber. Exemplarily, multiple mounting positions 32 are provided along the height direction on the inner wall of the second inner liner. These mounting positions are generally formed by strip-shaped protrusions (such as shelves) on the inner sides of the side panels, and the shelf can be positioned in any of these mounting positions. Obviously, this is only an exemplary description; those skilled in the art can determine the specific structural form, number, and formation method of the mounting positions according to actual needs. For example, a structure such as a bracket can be added inside the second inner liner, and mounting positions can be formed or provided on the bracket; or a structure capable of fixing the shelf can be provided on the door assembly (described below), and this structure can be used as a separate mounting position, or combined with the structure inside the second inner liner as a mounting position. In addition, the mounting position can also be any other reasonable structural form such as studs (multiple) with snap-fit ​​grooves, slide rails, etc. When there are multiple mounting positions, the structural forms of the multiple mounting positions and the methods of setting the shelf in different mounting positions can be the same or different.

[0114] In one possible implementation, the oven includes a lighting assembly, such as a lighting component 41. In this invention, the lighting component 41 is disposed on the first inner liner, and a light-transmitting structure 42 is disposed on the second inner liner at a position corresponding to the lighting component. This allows the light generated by the lighting component to reach the interior of the cooking chamber through the light-transmitting structure, thereby enabling visualization of the cooking process. In this example, a lighting component is disposed on each of the left and right sides of the first inner liner, with the front and rear positions of the left and right lighting components being approximately the same but at different heights. Correspondingly, light-transmitting structures are disposed at corresponding positions on the first side panel 223 and the second side panel 224, such as high-temperature resistant glass disposed on the first / second side panels.

[0115] In one possible implementation, the oven includes a door assembly, such as the door assembly being located on the side of the cooking body facing the operator (e.g., the front side), and the door assembly being configured to be flip-up, push-pull, or similar means within the cooking body. For example, the flip-up mechanism could be axially tilted upwards / downwards in the horizontal direction or axially tilted to the left / right in the vertical direction.

[0116] In one possible implementation, since baking requires the use of hot airflow as a cooking medium, the oven includes structures related to the generation and flow of hot airflow. For example, the oven may include a temperature-regulating fan and a heating coil as second heating components. The temperature-regulating fan primarily ensures that the temperature of the hot airflow delivered to the cooking chamber is as uniform and consistent as possible, while the second heating components primarily heat the cooking medium to ensure that the temperature of the hot airflow meets the cooking requirements. Exemplarily, a hot air chamber is formed between the first back plate of the first inner liner 21 and the second back plate 225 (fan cover) of the second inner liner 22. The temperature-regulating fan is fixedly mounted on the first back plate and is primarily located within the hot air chamber. The second heating components may be located within the hot air chamber or at other locations near the hot air chamber. Taking a heating coil as an example, if the heating coil is located within the hot air chamber, the temperature-regulating fan is generally located within the area enclosed by the heating coil. The fan cover is equipped with a return air inlet 41 and an air outlet 42. With the operation of the temperature-regulating fan, the airflow in the cooking chamber enters the hot air chamber through the return air inlet (where the airflow is heated by the second heating element), and then enters the cooking chamber through the air outlet, thus forming a circulating hot airflow. In this way, under the action of the temperature-regulating fan, the airflow in the cooking chamber is drawn into the hot air chamber through the return air inlet, heated by the second heating element, and transformed into a hot airflow carrying heat as a cooking medium. The temperature-regulating fan then throws the hot airflow towards the outer air outlet, thus sending it back into the inner chamber. This cycle delivers the hot airflow (the temperature and flow rate of which correspond to the cooking mode) to the surface of the food to be cooked, thereby cooking the food by hot air roasting.

[0117] It should be noted that the hot air chamber mentioned here is not an absolute complete chamber, but should be understood as an area used to house the main part of the temperature equalization fan. Therefore, those skilled in the art can determine the structural form, number and specific configuration of the hot air chamber according to actual needs.

[0118] For example, the return air vent is located on the fan shroud roughly corresponding to the position of the temperature-regulating fan. The return air vent may include multiple connecting holes, which generally form a disc-shaped structure. The supply air vent is located on the outer area of ​​the temperature-regulating fan within the fan shroud. Multiple supply air zones may be located around the return air vent, such as near the outer edge. These supply air zones may include one or more connecting holes, which generally form a strip-shaped structure. Clearly, those skilled in the art can determine the structural form, location, and configuration of the return air vent and supply air vent according to actual needs.

[0119] Based on the above structure, this utility model also provides a method for cleaning an oven, which is mainly used to remove the inner liner unit from the oven by quick disassembly and then clean it in the external space.

[0120] Main reference Figure 14 And continue to refer to Figures 1 to 13 In one possible implementation, the oven cleaning method mainly includes the following steps:

[0121] S1410. Pull the second inner liner out of the first inner liner.

[0122] In this example, the second inner liner is pulled out to a position that ensures it does not detach from the first inner liner and does not interfere with the removal of the second back panel from the substrate. Here, "not detaching" should be understood as the substrate not detaching from the first inner liner. In this example, the substrate is a frame, which can slide relative to the first inner liner without detaching from it; this can be achieved by selecting a suitable slide rail assembly.

[0123] For example, a slide rail is provided at approximately the center of the first / second side panel. By cooperating with another slide rail provided on the first inner liner, the second inner liner can be pulled out.

[0124] S1420, Remove the top plate from the matrix in the inner liner unit.

[0125] As a simple example, the base is roughly a frame, and the inner liner unit includes a top plate, first / second side plates, a second back plate, and a second bottom plate. Each inner liner unit is removable. In this example, the top plate can be removed from the frame by pulling it out. Obviously, the structural form, number, disassembly method / direction, etc. of the inner liner units can be flexibly adjusted according to actual needs.

[0126] S1430, Remove the first / second side plate from the base by pulling it upward → adjusting it to the middle position of the side plate by a combination of translation and rotation → pulling it upward.

[0127] S1440, Remove the second back plate in the inner liner unit from the base by flipping it forward and pulling it diagonally upward.

[0128] S1450, Remove the second bottom plate from the matrix in the inner liner unit.

[0129] After cleaning the exterior of the oven by removing the inner liner unit from the base, the cleaned inner liner unit is reinstalled onto the base, and the second inner liner is pushed into the first inner liner. At this point, the cleaning of the oven's inner liner components is essentially complete. After removing the inner liner unit, the cleanliness of the first inner liner, frame, sliding parts, and other structures can be observed. If cleaning is necessary, the corresponding parts can be cleaned manually by wiping.

[0130] For example, a centralized dismantling-cleaning-installation operation method is adopted. Obviously, it is also possible to clean only a portion of the inner liner units at a time, or to clean all the inner liner units but use a dismantling-cleaning-installation operation method one by one.

[0131] The oven can be cleaned directly in the sink, using a dishwasher or other pre-installed cleaning equipment, or a dedicated cleaning device can be provided. The cleaning device can be flexibly placed or fixedly installed at a specific location. For example, because the inner liner is a large sheet structure, a separate cleaning device often occupies a significant amount of space. Therefore, possible solutions include:

[0132] (1) Users can choose to clean it in a sink or with the help of a dishwasher.

[0133] (2) The oven is equipped with a cleaning device that can be installed in the kitchen space in a pull-out manner (or mechanically and / or signalally connected to the oven).

[0134] (3) The manufacturer has cleaning equipment. Since the oven is cleaned infrequently, the inner liner can be cleaned by the manufacturer through centralized cleaning (such as providing cleaning services) or by maintenance personnel bringing cleaning equipment to the door.

[0135] As can be seen, in the preferred embodiment of this utility model, the oven's inner liner assembly includes a first inner liner and a second inner liner. The first inner liner and the frame that serves as the base of the second inner liner are blocked by the inner liner unit, thus ensuring the cleanliness of the frame and the first inner liner. Based on this, by removing the inner liner unit (at least a portion of it) from the frame and then cleaning it separately from the outside of the oven, the cleaning effect of the oven is expected to be guaranteed. By pulling the second inner liner out of the first inner liner and then disassembling the inner liner unit, quick disassembly is ensured. By keeping the frame and the first inner liner in a continuous state, the reassembly difficulty after cleaning is reduced. The inclusion of a drain section ensures the cleanliness of the oven.

[0136] It should be noted that although the steps in the above embodiments are described in a specific order, those skilled in the art will understand that, in order to achieve the effects of this utility model, different steps do not necessarily have to be performed in this order. They can be performed simultaneously or in other orders, and some steps can be added, replaced, or omitted. For example, the removal order of the first / second side plates can be flexibly adjusted, and in the case where the first heating component is fixed to the top plate, a step of releasing the constraint between the first heating component and the top plate is also required.

[0137] It should be noted that although the oven cleaning method described above is presented as an example, those skilled in the art will understand that this invention is not limited thereto. In fact, users can flexibly adjust the relevant steps and parameters according to actual application scenarios. For example, when removing the first / second side panels, the preset distance, preset angle, side panel center position, and specific operation method for reaching the center position can be flexibly selected according to actual needs. Similarly, when removing the second back panel, the amount of rotation can be flexibly selected according to actual needs.

[0138] The technical solution of this utility model has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
