Abstract
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

[0052] 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.
[0053] 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.
[0054] 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.
[0055] 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.
[0056] The following will refer to the appendix. Figures 1 to 9 The present invention is described in at least a portion thereof.
[0057] Main reference Figures 1 to 9 In one possible implementation, the oven 100 mainly includes a cooking body, which forms a cooking chamber for holding food to be cooked. The cooking body includes a cabinet 1 and an inner liner assembly 2. An operation panel 11 for display and interaction (such as mode selection and parameter setting) is located near the top of the front side of the cabinet 1. The inner liner assembly 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 is disposed within the cabinet, and the second inner liner is removably disposed within the first inner liner.
[0058] 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 in this example may also be called a fan cover), and a bottom plate 226. Each inner liner unit is detachably disposed on the frame. Based on this, by removing the top plate, 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.
[0059] 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:
[0060] (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 or a carrier for installing it may be added to the frame (such as a plate structure, strip structure, block structure, etc.).
[0061] (2) One or more of the top plate, bottom plate, second back plate, and 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.
[0062] (3) One or more of the top plate, bottom plate, second back plate, and first / second side plate may include multiple sub-parts. Among these sub-parts, some are fixedly installed or integrally formed on the frame. In this case, the sub-parts that are not removed from the frame can also be understood as the base. For example, the multiple sub-parts of the inner liner unit can be spliced (e.g., directly butt-jointed, spliced with the aid of a carrier (plate structure, support frame, frame, etc.)) or stacked (e.g., partially overlapping / fully overlapping, stacking of two or more layers) to form the corresponding inner liner unit. Taking the stacking as an example, the inner layer can be disassembled and washed.
[0063] 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).
[0064] (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:
[0065] (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.
[0066] (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).
[0067] It is understood that those skilled in the art can flexibly choose the specific method of removably mounting each inner liner unit to the base, as well as the corresponding method / direction / specific operation for removing it from the base, according to 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.
[0068] Regarding 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 removal of the first / second side panels can be 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] Main reference Figures 5 to 9 In one possible implementation, an insertion space 2263 is formed on the base plate 226. In this example, the insertion space is approximately a slit, allowing the lower part (lower side edge) of the first side plate to be inserted into it. In this example, the base plate 226 is provided with a first side plate limiting structure 2261 and a second side plate limiting structure 2262, forming an insertion space 2263 that can cooperate with the first side plate. In this example, the first side plate limiting structure 2261 is a flange extending upwards from the outer edge of the base plate, and the second side plate limiting structure 2262 is a roughly L-shaped pressed profile located at each of the four corners of the base plate. In this example, the cross-section of the pressed profile is approximately an isosceles trapezoid.
[0071] Obviously, the combination of flange and pressing is only an exemplary description of forming the insertion space. Those skilled in the art can determine the structural form of the insertion space and its specific formation method according to actual needs. For example, the second side plate limiting structure can be one or more strip structures parallel to the flange corresponding to the first side plate, or the insertion space can be formed directly inside a structure (such as an insertion space formed on the insertion seat). The lower side of the first side plate and the insertion space can be tightly fitted or have a certain margin. This can include, but is not limited to: a sealing structure provided at the position of the bottom plate corresponding to the insertion space to ensure the sealing performance of the first / second side plates in the assembled state; a buffer structure provided at the position of the bottom plate corresponding to the insertion space to ensure stability during installation; the first / second side plate limiting structure can also be provided on the frame. For example, one of the first and second side plate limiting structures is provided on the bottom plate, and the other is provided on the frame. In this functional case, the insertion space can be considered to be formed by the frame and the bottom plate (located between the two).
[0072] In one possible implementation, the frame has an operation avoidance structure 1211 located above (on the upper side) near the first side plate. In this example, the operation avoidance structure is a strip-shaped recessed molding, allowing the user to pull the first side plate upwards by inserting their hand into the position corresponding to the recessed molding. Clearly, those skilled in the art can determine the form, number, and specific location of the operation avoidance structure according to actual needs.
[0073] 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, pulleys can also be added to the bottom of the second inner liner to ensure convenience and stability during the sliding process.
[0074] 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.
[0075] 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 frame and the corresponding positions of the first / second side plates from above through the two bends on both sides. (Main reference) Figure 4Taking the connection between the base 221, top plate 222, and first side plate 223 as an example, in this example, the frame serving as the base 221 is provided with a base connecting structure 2211, and the first side plate 223 is provided with a side plate connecting structure 2231 that can cooperate with the base connecting structure 2211. In this way, the first side plate 223 can be connected to each other by means of the cooperation between the base connecting structure 2211 and the side plate connecting structure 2231. In this example, the base connecting structure 2211 consists of two parallel flanges extending inward from the inside of the frame, and the side plate connecting structure 2231 is roughly a bend, with the horizontal part of the bend able to rest on the upper surface of the upper flange, and the vertical part of the bend able to adhere to the outer surface of the frame. 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.
[0076] 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.
[0077] In one possible implementation, the second inner liner includes a 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 limiting component includes a first limiting structure 261, as in this example, where the first limiting structure is provided on both the first side plate 223 and the second side plate 224. The first limiting structure is a protrusion, and protrusions are also provided on the inner sides of the first and second side plates near the rear. Correspondingly, a second limiting structure 262 is provided on the inner side of the top plate, capable of abutting against the protrusions in the front-back direction. As in this example, the rear end of the aforementioned water-gathering structure has a surface capable of abutting against the protrusions. In this way, the integrated water-gathering structure and the second 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 limiting component ensures the stability of the top plate in the assembled state. Obviously, the structural form, number, and setting position of the first / second limiting structure can be flexibly selected according to actual needs. For example, the first / second limiting structure can also be a baffle, flange, limiting block, etc. The first limiting structure can cooperate with the second limiting structure, or it can directly cooperate with existing structures / positions such as the rear end face of the top plate. The first 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 first limiting structures set on the first side plate and the second side plate can be the same or different.
[0078] 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, or 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 2, 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 211 of the first inner liner 21 through 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 slots / holes can be provided on the top plate. The first heating component is fixed to the inside of the top plate by means of a first connecting structure such as a mounting clip or mounting buckle, which cooperates with the first mounting structure. In this case, if it is necessary to remove the top plate from the frame, the constraint between the top plate and the first heating component needs to be released.
[0079] 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.
[0080] 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.
[0081] In one possible implementation, the oven includes a lighting assembly, such as at least one lighting element 41. As in this invention, the lighting element 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 element. This allows the light generated by the lighting element 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 element 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 elements 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.
[0082] 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.
[0083] 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 includes a temperature-regulating fan 51 and a second heating element 52, such as a heating coil. 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 element primarily heats 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 211 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 211 and is mainly located within the hot air chamber. The second heating element can 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 53 and an air outlet 54. 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 and thus 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.
[0084] 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.
[0085] 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.
[0086] 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.
[0087] Main reference Figure 10 In one possible implementation, the oven cleaning method mainly includes the following steps:
[0088] S1010. Pull the second inner liner out of the first inner liner.
[0089] 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.
[0090] 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.
[0091] S1020, At least a portion of the inner liner monomer is removed from the matrix.
[0092] 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 bottom plate. Each inner liner unit is removed from the frame by extraction. The removal sequence is: top plate, first / second side plates, second back plate, and bottom plate. Clearly, the structure, number, and removal method / direction of the removable inner liner units can be flexibly adjusted according to actual needs.
[0093] S1030. Clean the outer shell of the oven by removing the inner liner unit from the base.
[0094] 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.
[0095] 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:
[0096] (1) Users can choose to clean it in a sink or with the help of a dishwasher.
[0097] (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).
[0098] (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.
[0099] S1040. Install the cleaned inner liner unit onto the base. After installation, push the second inner liner into the first inner liner.
[0100] At this point, the cleaning of the oven's inner liner components is basically complete. After removing the individual inner liner units, you can observe the cleanliness of the first inner liner, frame, sliding parts, and other structures. If cleaning is necessary, use manual wiping or other methods to clean the corresponding parts.
[0101] Main reference Figure 11 In one specific implementation, the oven cleaning method mainly includes the following steps:
[0102] S1110. Pull the second inner liner out of the first inner liner.
[0103] S1120, Remove the top plate from the matrix in the inner liner unit.
[0104] S1130, Remove the first / second side plate from the substrate. In this invention, the step of removing the first / second side plate from the substrate includes:
[0105] S301. Pull the first / second side plate upwards by a preset distance (such as a small distance of ≤5cm, for example, about 1cm) so that the bottom of the first / second side plate is freed from the limitation of the insertion space.
[0106] With the completion of this action, the upper part of the first / second side panel is also released 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 box, and other structures. Therefore, this utility model improves the removal method as follows.
[0107] S302, Adjust the first / second side plate to the middle position.
[0108] In this example, the first / second side plate base is adjusted to an intermediate posture within the plane where the base plate is located or within a plane parallel to the base plate. Other reasonable postures could also be used, such as an inclined posture with height differences between different parts.
[0109] For example, after translating the first / second side panel by a preset distance (e.g., ≤5cm) along the width direction, it can be rotated by a preset angle (this rotation can be along the inner side after translation, or approximately along the axis corresponding to the inner side, allowing for some displacement of the inner side itself). This ensures that, at least in this posture, when the first / second side panel is pulled upwards vertically, it will not interfere with the structure of the oven or the structure of the installation space (e.g., cabinets) where the oven is located. In this example, the base plate is approximately rectangular, and the intermediate posture is such that the first / second side panel is approximately positioned on the diagonal of the base plate (e.g., rotated approximately 45-60°). This position can be flexibly adjusted while ensuring no interference. That is, when the first / second side panel is in the intermediate posture, the relevant potentially interfering structures do not overlap with the projection of the first / second side panel in the horizontal plane.
[0110] Obviously, the combination of translation followed by rotation is only an exemplary description. Those skilled in the art can determine the specific operation method according to actual needs, such as directly adjusting to the intermediate posture through any other feasible trajectory (the trajectory can be relatively free or somewhat limited).
[0111] To ensure repeatability of disassembly, appropriate limiting structures can be used to determine the specific position of the 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.
[0112] S303. Pull the first / second side panel out of the oven in a roughly vertically upward manner.
[0113] 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.
[0114] S1140. Remove the second back plate and bottom plate from the substrate in the inner liner unit. The second back plate and bottom plate can be removed from the substrate by any reasonable method such as horizontal extraction or oblique upward extraction.
[0115] 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, which serves as the base of the second inner liner, are blocked by the inner liner unit of the second inner liner, 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, it is expected to ensure the cleaning effect of the oven. Any reasonable cleaning method can be flexibly used to clean the inner liner unit. For example, by adjusting the first / second side plates of the inner liner unit to a middle position after pulling them upward a small distance and then pulling them upward, the operability of removing the first / second side plates is ensured. By pulling the second inner liner out of the first inner liner before disassembling the inner liner unit, the operability of quick disassembly is ensured. By keeping the frame and the first inner liner in a continuous state, the assembly difficulty after cleaning is reduced.
[0116] 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, 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.
[0117] 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, such as the specific disassembly method of the inner liner unit and whether there are sub-parts in each inner liner unit that do not need to be disassembled, etc., according to actual needs.
[0118] 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.
