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
[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 the above, the present invention provides a cooking device, the cooking device comprising: a housing and an inner liner assembly disposed in the housing, the inner liner assembly comprising: a first inner liner; and a second inner liner disposed in the first inner liner in a removable manner; wherein, the second inner liner comprises a frame and a fixed portion and a movable portion disposed in the frame, the movable portion comprising at least one inner liner unit, at least a portion of the inner liner unit being detachably disposed in the frame.
[0007] This configuration allows for external cleaning of the cooking appliance after at least a portion of the inner liner unit has been removed from the frame. This, in turn, is expected to improve the cleaning efficiency of the cooking appliance.
[0008] It is understood that those skilled in the art can determine the structural form of the fixed / movable part, the number of its components, the relative positions of the components in the fixed / movable part, the relative positions between the fixed part and the movable part, and the specific manner in which they are set on the frame, etc., according to actual needs. Taking the fixed part as an example, it can be made of an integral molding, welding, or other irreversible connection methods, and it is not easy to disassemble so that it does not need to be disassembled during the cleaning process.
[0009] In one possible implementation of the above-described cooking device, the movable part includes a top plate that can be removed from the frame, and the second inner pot is disposed in a pull-out but non-detachable manner within the first inner pot.
[0010] This configuration allows for cleaning the top plate from the outside of the cooking appliance after it is removed, while other parts in the oven area can be cleaned by methods such as manual wiping.
[0011] In one possible implementation of the above-described cooking device, the movable part includes a top plate and a back plate, which are removable from the frame, and the second inner pot is disposed in a pull-out but non-detachable manner within the first inner pot.
[0012] This configuration allows for external cleaning of the top and back panels after removal, while the oven area can be cleaned by hand wiping. When cleaning the cooking equipment using this method, with the top and back panels removed and the second inner liner fully pulled out, all surfaces are clearly visible and easily accessible. Furthermore, good cleaning results can be achieved even with the inner liner not fully pulled out. This is particularly suitable for situations where the back panel is heavily soiled or where space is limited for installing the cooking equipment.
[0013] In one possible implementation of the cooking device described above, the inner pot unit includes a plurality of sub-parts, at least a portion of which can be removably disposed in other parts of the inner pot unit or in the frame.
[0014] In one possible implementation of the aforementioned cooking equipment, the inner pot unit comprises multiple spliced sub-parts.
[0015] In one possible implementation of the cooking device described above, the inner pot unit comprises at least two sub-parts stacked together, with at least the inner sub-parts being removably disposed on the frame.
[0016] In one possible implementation of the cooking device described above, the frame includes a first sub-frame and a second sub-frame, which are configured to be relatively scalable.
[0017] In one possible implementation of the cooking device described above, the second sub-frame is fully housed within the first sub-frame in its assembled state.
[0018] In one possible implementation of the cooking equipment described above, the first sub-frame, when assembled, can be spliced with the second sub-frame to form the frame.
[0019] In a second aspect, 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; and a second inner liner disposed within the first inner liner in a retractable and detachable manner. The second inner liner includes a frame and at least one inner liner unit disposed in the frame.
[0020] With this configuration, the second inner pot can be completely removed from the first inner pot, allowing for cleaning of the outside of the cooking appliance. Attached Figure Description

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.
[0040] 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.
[0041] 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.
[0042] 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.
[0043] The following will refer to the appendix. Figures 1 to 5 The present invention is described in at least a portion thereof.
[0044] Main reference Figures 1 to 4 In one possible implementation, the oven 100 mainly includes a cooking body 1, which includes a housing 1 and an inner liner assembly 2. The inner liner assembly includes a first inner liner 21 disposed in the housing and a second inner liner 22 disposed in the first inner liner 21. The second inner liner forms a cooking chamber and is disposed in the first inner liner 21 in a retractable manner.
[0045] In one possible implementation, the second inner liner 22 includes a frame 221 and one or more inner liner units disposed on the frame 221, at least a portion of which is removably disposed on the frame 221. For example, in this example, the inner liner unit includes a top plate 222, first side plates 223 / second side plates 224 on the left / right sides, a back plate 225 (which may also be called a fan cover in this example), and a bottom plate 226. Among each inner liner unit, the portion fixedly disposed on the frame can be referred to as the fixed portion, and the portion removable from the frame can be referred to as the movable portion. Exemplarily, one or more of the top plate, first / second side plates, back plate, and bottom plate are fixedly disposed on (not removable) or integrally formed on the frame; in this case, that portion can be understood as the fixed portion.
[0046] The top plate, first / second side plates, bottom plate, and back plate may include one or more sub-parts. Some of these sub-parts may be fixedly mounted or integrally formed within the frame. For example, the sub-parts of the inner liner unit can be joined (e.g., directly butt-fitting, joining using a carrier (plate structure, support frame, etc.)) or stacked (e.g., partial / full overlap, two / more layers). Taking stacking as an example, the inner layers can be disassembled and washed.
[0047] The frame can be a single, integral structure (fixedly connected or molded as a single piece), or it can be a combination of multiple sub-frames, such as multiple sub-frames forming the frame in an assembled state. When cleaning the inner liner assembly is required, the multiple sub-frames can move relative to each other to facilitate the removal of the inner liner unit. For example:
[0048] (1) 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-back direction. In this configuration, 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 back panel from the frame to be moved forward, thereby avoiding interference with positions such as the control panel of an oven.
[0049] (2) The frame includes a first sub-frame (equivalent to the front half of the current frame) and a second sub-frame (equivalent 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 a 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).
[0050] Based on this, by removing one or more of the movable parts from the frame, users can easily perform deep cleaning of the removed inner liner unit from the outside of the oven by means of methods such as placing it in a dishwasher, manually cleaning it in a sink, or targeting specific locations for cleaning the inner liner unit.
[0051] It is understood that those skilled in the art can flexibly choose the specific method of removably mounting each inner liner unit to the frame, as well as the corresponding method / direction / specific operation for removing it from the frame, 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, flipping, etc.
[0052] In one possible implementation, the inner liner assembly includes a sliding portion 23, which comprises a first sliding structure disposed in the first inner liner and a second sliding structure disposed in the second inner liner. For example, in this example, the first sliding structure 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 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.
[0053] In one possible implementation, the oven further includes a door assembly 3, disposed on the side of the cooking body facing the operator (e.g., the front side). The door assembly may be configured to be flip-up, push-pull, or similar configuration within the cooking body. For example, a flip-up configuration could be an upward / downward tilt along a horizontal axis or a left / right tilt along a vertical axis. Exemplarily, the door assembly 3 is configured to be flip-down, and it is provided with a handle for user operation.
[0054] 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.
[0055] In one possible implementation, the oven's cooking chamber is provided with a shelf 51 (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 52 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 a 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.
[0056] 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 and heating elements such as heating coils. 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 heating elements primarily heat the cooking medium to ensure that the temperature of the hot airflow meets the cooking requirements. The temperature-regulating fan and heating elements are located on the rear side of the back panel. Thus, under the action of the temperature-regulating fan, air from the cooking chamber is drawn into the hot air chamber behind the back panel through the return air vent 61. The heating elements then heat the air, transforming it into hot airflow carrying heat as the cooking medium. The temperature-regulating fan then propels the hot airflow towards the outer air outlet 62, thus sending it back into the inner cavity. This cycle delivers 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 using a hot air baking method.
[0057] Based on the above structure, this utility model also provides a possible method for cleaning an oven, which is mainly used to remove at least a portion of the inner liner unit (and frame) from the oven by means of quick disassembly, and then clean it in the external space.
[0058] Example 1
[0059] Main reference Figure 3 In this example, the fixed parts of each inner cavity unit include the first / second side panels, the back panel, and the bottom panel, while the movable parts include the top panel. The oven cleaning process mainly includes the following steps:
[0060] S310. Pull the second inner liner out of the first inner liner.
[0061] 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 top plate from the frame. Here, "not detaching" should be understood as the frame not detaching from the first inner liner. If the frame can slide relative to the first inner liner but does not detach from it, this can be achieved by selecting a suitable slide rail assembly.
[0062] S320, Remove the top plate from the frame in the inner liner unit.
[0063] For example, the top panel can be removed from the frame by pulling it out diagonally upwards or horizontally.
[0064] S330. Clean the top plate that has been removed from the frame on the outside of the oven.
[0065] S340. Clean the first / second side panels, back panel, bottom panel, etc., of the frame by wiping or other means without removing them from the oven.
[0066] S350. Install the cleaned top plate onto the frame. After installation, push the second inner liner into the first inner liner.
[0067] When cleaning the cooking equipment using this method, after removing the top panel and pulling out the second inner pot, all surfaces are clearly visible and easily accessible. This simplifies disassembly and assembly, allows for a comprehensive assessment of the level of dirt, and facilitates cleaning of individual parts. This cleaning method is suitable for situations where not disassembling the entire unit would negatively impact visibility and ease of operation, but where users are resistant to the disassembly process. It is particularly suitable for users who are less accepting of excessive disassembly.
[0068] Example 2
[0069] Main reference Figure 4 This embodiment is similar to Embodiment 2, except that in this example, the fixed part of each inner liner unit includes the first / second side plate and the bottom plate, and the movable part includes the top plate and the back plate.
[0070] On the one hand, the back panel is positioned further back than other inner chamber units. On the other hand, the hot air chamber formed behind the back panel is a flow path for hot air. Therefore, when cleaning it in situ, the ease of operation may be less than other parts, and there may be areas to be cleaned that are not visible. In view of this, the cleaning method of this embodiment is proposed. Compared with Embodiment 1, this embodiment significantly improves the cleaning effect of the oven while slightly increasing the amount of disassembly and assembly work.
[0071] When cleaning cooking equipment using this method, after removing the top and back panels, all surfaces are clearly visible and easily accessible when the second inner pot is fully pulled out. Furthermore, good cleaning results can be achieved even with the inner pot not fully pulled out. This method is particularly suitable for situations where the back panel is heavily soiled or where the space where the cooking equipment is installed is relatively limited.
[0072] Example 3
[0073] Main reference Figure 5 In one possible implementation, the oven cleaning method mainly includes the following steps:
[0074] S510. Pull the second inner liner out of the first inner liner and detach the second inner liner from the first inner liner.
[0075] If the second sliding structure in the sliding part can be kept fixedly connected to the frame, the sliding connection between the first and second sliding structures can be released. Alternatively, the fixed connection between the frame and the second sliding structure in the sliding part can be released.
[0076] S520, Transfer the second inner cavity to the target position outside the oven.
[0077] The target location can be a dedicated worktop, or any kitchen countertop, tabletop, coffee table, floor, or other location that can accommodate the second inner liner.
[0078] S530. At the target location, remove the top plate, first / second side plates, back plate, and bottom plate from the frame of the inner liner unit. That is, remove the inner liner unit from the outside of the oven.
[0079] In this example, the top plate, first / second side plates, back plate, and bottom plate of each inner liner unit are all movable parts. Obviously, some of them could also be changed to fixed parts.
[0080] S540. Clean the exterior of the oven, removing the inner liner unit from the frame. Also, the frame can be cleaned, for example, by wiping, depending on the situation.
[0081] As with embodiments 1 to 3 described above, the inner liner unit, which has been removed from the frame, can be cleaned directly in a sink, or cleaned using a pre-installed cleaning device such as a dishwasher, or a dedicated cleaning device can be provided for the oven. For example, since the inner liner unit is a large sheet structure, a separate cleaning device often occupies a significant amount of space. Therefore, alternative solutions include:
[0082] (1) Users can choose to clean it in a sink or with the help of a dishwasher.
[0083] (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).
[0084] (3) The manufacturer has cleaning equipment. Since the oven is cleaned infrequently, the removed inner liner unit can be cleaned by the manufacturer's centralized cleaning (such as providing cleaning services) or by the maintenance personnel bringing cleaning equipment to the door.
[0085] S550, complete the assembly and push the second inner liner into the first inner liner.
[0086] For example, after the cleaned inner liner unit is installed onto the frame, the assembled second inner liner is then installed onto the first inner liner to complete the assembly. Alternatively, after the frame and the first inner liner are assembled, some or all of the inner liner units can be installed onto the frame. In other words, the order in which the inner liner units are installed onto the frame can be flexibly adjusted.
[0087] At this point, the cleaning of the oven's inner liner components is basically complete. After removing the second inner liner, you can observe the cleanliness of the first inner liner, the remaining parts in the sliding section, and other structures. If cleaning is necessary, use manual wiping or other methods to clean the corresponding parts.
[0088] 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 cleanliness of the first inner liner is ensured by the shielding provided by the second inner liner. Based on this, by removing at least a portion of the inner liner unit from the frame and then cleaning it separately from the outside of the oven, the cleaning effect of the oven can be guaranteed. Any reasonable cleaning method can be flexibly used to clean the inner liner unit. The ease of quick disassembly is ensured by pulling the second inner liner out of the first inner liner or by detaching the second inner liner from the oven before disassembling the inner liner unit. The specific structure of the inner liner unit included in the movable part, and whether to detach the frame from the first inner liner, can be selected according to actual needs to ensure that the assembly difficulty is within the user's operational range.
[0089] 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 executed in this order. They can be executed simultaneously or in other orders, and some steps can be added, replaced, or omitted. For example, in the case where the heating tube is fixed in the top plate, a step of releasing the constraint between the heating tube and the top plate is also required.
[0090] 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 structural form of the inner liner unit, the removable inner liner unit, the specific disassembly method of the inner liner unit, the number of sub-parts contained in each inner liner unit, and whether there are sub-parts in the inner liner unit that do not need to be disassembled, etc., which can be flexibly selected according to actual needs.
[0091] 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.
