Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and in particular to a cooking appliance and a cleaning method thereof. Background Art

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

[0003] The principle behind grilling is that a circulating hot air flow is supplied to the inner pot (enclosed within the cooking chamber) where the food is to be cooked, thereby cooking the food through hot air grilling. The principle behind steaming is that high-temperature steam is supplied to the inner pot where the food is to be cooked, thereby cooking the food through pure steaming. There are also cooking methods that combine steaming and grilling (such as the tender grilling mode).

[0004] Take the oven (which uses the baking method alone) as an example, and the ingredients to be cooked are meat ingredients such as chicken / goose / lamb, as an example. Since these ingredients usually contain oil and moisture, during the cooking process (heat-cooking), it is inevitable that oil-containing substances such as oil / oil stains / oil residues will splash / drip / fall onto the top / side / bottom wall of the inner pot (and the inner wall of the door body). Accordingly, in order to ensure the performance of the cooking equipment and the user experience, the oven needs to be cleaned in a timely manner. Among the current cleaning methods, high-temperature pyrolysis steam cleaning generally has the problem of poor cleaning effect, so its recognition is not high. The cleaning effect of wiping / rinsing cleaning can be better in theory, but due to the limitations of the specific implementation method, the current cleaning effect still has room for improvement, such as often having problems including but not limited to cumbersome / inconvenient operation, incomplete cleaning of all / partial areas, and certain operational difficulties for users.

[0044] The preferred embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application. For example, although the present embodiment introduces the cooking device in conjunction with an oven that only includes the cooking method of baking, this is not intended to limit the scope of protection of the present application. Without departing from the principles of the present application, those skilled in the art can apply the present application to other application product forms, such as a steam-bake all-in-one machine, a steam-bake-fry all-in-one machine, a double-cavity oven / steam oven, etc. In addition, in addition to being applicable to cooking equipment that includes the cooking method of baking, the present application is also applicable to cooking equipment for other cooking methods (such as frying, etc.) that require similar cleaning.

[0045] It should be noted that, in the description of this application, 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. This is merely for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, it should not be understood as limiting this application. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0046] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "installed," "set," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0047] In addition, to better illustrate the present application, numerous specific details are provided in the following detailed description. Those skilled in the art will appreciate that the present application can still be implemented without certain specific details. In some instances, the structural form of the oven, the cooking principles / processes / parameters of baking, etc., which are well known to those skilled in the art, are not described in detail in order to highlight the main purpose of the present application.

[0048] The following will refer to the attached Figures 1 to 4 At least part of the present application is described.

[0049] Main reference Figures 1 to 4In one possible embodiment, an oven 100 includes a cooking body, which includes a housing 1 and an inner pot assembly 2 disposed within the housing 1. For example, an operation panel 11 for displaying and interacting with functions (such as mode selection and parameter setting) is disposed near the top of the front side of the housing 1. The inner pot assembly 2 includes a first inner pot 21 disposed within the housing 1 and a second inner pot 22 disposed within the first inner pot. The second inner pot forms a cooking chamber for cooking food contained therein. The second inner pot 22 is removable from the first inner pot 21. Specifically, after being completely separated from the first inner pot, the second inner pot can be placed outside the oven. The second inner pot 22 includes multiple inner pot portions, at least one of which is removable relative to the other portions.

[0050] In this example, the second liner 22 is disposed in a retractable manner within the first liner 21. Obviously, the second liner 22 can also be connected to the first liner in a manner that releases the constraint. For example, the first and second liner can be fixedly connected by a pair of structures that cooperate with each other (such as arc-shaped grooves / arc-shaped protrusions, elastic structures / holes, etc.). By lifting the second liner upward, the constraint between the two can be released, thereby removing the second liner from the first liner.

[0051] As in this example, the liner part includes two, such as the first liner part 221 and the second liner part 222, respectively. The first liner part 221 is located above the second liner part 222, and the first liner part 221 and the second liner part 222 form the second liner 22 by directly matching and connecting. As in this example, the first liner part 221 and the second liner part 222 are roughly symmetrical in structure except for the structure at the matching connection position, the connection between the second liner part below and the first liner (such as sliding), etc. Obviously, those skilled in the art can determine the structural form, number, relative position of the liner part and the specific way of forming the second liner according to actual needs. For example, it can be: the first liner part and the second liner part can be differently set in length / width / height / shape; the first liner part and the second liner part form the second liner by indirectly matching and connecting in a way such as being both set on a carrier such as a frame; the liner part includes more, such as a middle part and two parts located on the upper and lower sides of the middle part; etc.

[0052] In one possible embodiment, the first inner container portion 221 includes an integrally formed top panel 2211, two first half side panels 2212 on the left and right sides, and a first half back panel 2213. The second inner container portion 222 includes an integrally formed bottom panel 2221, two second half side panels 2222 on the left and right sides, and a second half back panel 2223. The first half side panels 2212 and the second half side panels 2222 on the corresponding sides form the side panels of the second inner container, while the first half back panel 2213 and the second half back panel 2223 form the back panel of the second inner container.

[0053] Obviously, the structural form of the above-mentioned sub-parts and the one-piece molding method between each sub-part are only exemplary descriptions of the first / second inner liner part. Those skilled in the art can determine the structural form of the sub-parts included in the first / second inner liner part, the relative positions between each sub-part and the specific method of constituting the first / second inner liner part according to actual needs, such as: adjacent sub-parts adopt a detachable fixed connection (such as screw connection, mortise and tenon connection, plug-in connection, snap connection, etc.) or a fixed connection that does not allow repeated disassembly (such as welding, bonding, etc. irreversible fixed connection method); some of the multiple sub-parts are non-detachable (such as one-piece molding or second fixed connection), and the other part is detachable (such as the first fixed connection); the top plate includes multiple sub-parts, and the first inner liner part includes two sub-parts spliced ​​on the left and right; etc.

[0054] In one possible embodiment, the lower second inner pot portion 222 is disposed in a push-pull manner within the first inner pot 11. On this basis, after the second inner pot is pulled out of the first inner pot, the upper first inner pot portion can be further separated from the lower second inner pot portion, thereby facilitating the user to deeply clean each inner pot portion outside the oven by placing the inner pot portion in a dishwasher (e.g., the separated first and second inner pot portions are similar to pots), manually cleaning in a sink, or cleaning a specific target location for cleaning the first and second inner pot portions.

[0055] In one possible embodiment, the liner assembly 2 includes a sliding portion 23, which includes a first sliding structure 231 provided on the first liner 21 and a second sliding structure 232 provided on the second liner 22. For example, in this example, the first sliding structure 231 includes a pair of slide rails provided on both sides of the bottom of the first liner. Accordingly, another pair of slide rails serving as the second sliding structure 232 is provided at corresponding positions on the bottom of the second liner portion. The second liner portion and the slide rails serving as the second sliding structure are detachably connected. For example, a first mating feature 233 is provided on the slide rail serving as the second sliding structure. For example, the first mating feature 233 includes a pair of protrusions. Accordingly, a second mating feature 234 capable of mating with the first mating feature is provided on the second liner portion. For example, the second mating feature 234 includes a pair of receiving grooves. If the receiving groove has an opening in the direction corresponding to the side panel, the reliability of the sliding connection can be ensured during the process of pulling the second liner portion out of the first liner.

[0056] Obviously, those skilled in the art can determine the structural form, installation position of the first / second sliding structure, and the specific method for the second liner part to be able to be separated from the first liner according to actual needs. For example, a slide rail of any structural form can be selected, and the slide rail can be located at the intersection of the bottom and side of the liner assembly, the middle of the side panel along the height direction, etc., and any other reasonable method can be adopted to ensure the detachability of the second liner part (such as the first / second matching feature structure that can be released by a pressing operation, etc.). For example, the slide rail assembly is replaced with a directly detachable sliding connection pair.

[0057] In one possible embodiment, the liner assembly 2 includes a connecting portion 24, which includes a first connecting structure 241 provided on the first liner portion 221 and a second connecting structure 242 provided on the second liner portion 222. In this example, a first protruding portion 251 extends outward from the lower edge of the first liner portion (e.g., at positions corresponding to the two first half side panels and the first half back panel). The first protruding portion is provided with a downwardly protruding strip structure (flange) that serves as the first connecting structure 241. Correspondingly, a second protruding portion 252 extends outward from the upper edge of the second liner portion. The second protruding portion is provided with a strip groove (groove) that serves as the second connecting structure 242. In this way, thanks to the deadweight of the first liner portion and the interaction between the groove and the flange, the second liner can fit tightly in the assembled state. In this example, the interaction between the flange and the groove on the back can serve as a limiter. The interaction between the flange and the groove on the side serves as a sliding connection, making it easy for the user to remove the two by sliding the connection. Obviously, other removal methods such as directly removing the first inner liner part from the second inner liner part in a vertical direction may also be adopted.

[0058] In one possible embodiment, the top plate of the first inner liner portion is a structural form in which the middle portion is higher than at least a portion of the outer edge. As in this example, the top plate is high in the middle and low on both sides with a certain curvature (the height of the middle portion is roughly equal to the middle of the outer edge of the back side). In this way, condensed water and splashed oil on the top can be guided to flow along the edge to the side wall of the second inner liner. Obviously, any other reasonable method can also be adopted, such as a combination of inclined surfaces, setting inclined surfaces / curved surfaces only near the edge, lowering the height of the outer edge of the back side, etc.

[0059] In one possible embodiment, the two first half side panels of the first inner container are inclined outward from top to bottom, such as inclined surfaces, curved surfaces, etc. In this way, condensed water, oil, etc. reaching both sides of the top panel can flow to the bottom of the second inner container.

[0060] In this example, the upper first extension 251 generally comprises a transverse portion, with a flange disposed approximately in the middle of the transverse portion. A water-collecting structure 2511 is disposed on the upper surface of the first extension at a position corresponding to the flange. In this example, water-collecting structure 2511 is a trough-shaped structure. The lower second extension generally comprises an L-shaped structure, with a groove disposed in the transverse portion of the L-shaped structure. This allows condensed water, oil, and the like that reaches both sides of the top plate to be intercepted and directed to the middle of the second inner liner. Both the trough-shaped structure and the L-shaped structure disposed on the upper surface of the first extension can collect condensed water and oil that flow to the middle of the second inner liner.

[0061] Obviously, those skilled in the art can determine the structural form, number, and location of the first / second connecting structures according to actual needs. For example, the positions of the flange and the groove can be swapped, the first / second protruding portion can be extended inward or the first / second connecting structure can be directly provided without extending, and the first / second connecting structure can be fixedly connected to the first / second liner portion or integrally formed in any reasonable form of mating pair (such as a combination of a dot-shaped protrusion and a strip-shaped groove, a mating pair along the horizontal direction, etc.).

[0062] Obviously, the cooperation between the above-mentioned flange and groove is only an exemplary connection method between the first inner liner part and the second inner liner part. Those skilled in the art can adopt any other reasonable methods such as screw connection, clip connection, etc. to achieve a detachable connection between the two according to needs.

[0063] In one possible embodiment, the oven includes a door assembly 3. For example, the door assembly 3 can be disposed on the side of the cooking body facing the operator (e.g., the front side) in a reversible, push-pull, or other manner, thereby enabling food removal and placement operations similar to the aforementioned push-pull operation of the second inner pot. For example, the door assembly 3 can be flipped upward / downward along a horizontal axis or flipped left / right along a vertical axis.

[0064] In one possible embodiment, one or more mounting positions 4 are provided in the cooking chamber (e.g., multiple mounting positions are provided along the height direction). For example, the mounting position may include a shelf directly provided on the inner side of the second inner pot, or a structure such as a bracket may be added to the inner side of the second inner pot and a structure may be formed on the structure. For example, an oven is usually provided with a shelf, and the ingredients to be cooked are placed directly on the shelf or on a container (such as a tray) placed on the shelf. The shelf may be provided at the mounting position. Obviously, this is only an exemplary description, and those skilled in the art may determine the specific structural form, number, and formation method of the mounting position according to actual needs. For example, the mounting position may also be a plurality of studs with a snap-in groove, etc.

[0065] Based on the above structure, the present application also provides an oven cleaning method, which is mainly used to remove the second inner pot in the inner pot assembly from the oven by quick disassembly and then clean it in the external space.

[0066] Main reference Figure 5 And continue to refer to Figures 1 to 4 In one possible implementation, the oven cleaning method mainly includes the following steps:

[0067] S510: Pull the second inner container out of the first inner container.

[0068] As in this example, with the help of a pair of slide rail assemblies, the second liner is pulled out to a position where the first liner part can be removed from the second liner part. At this time, the second liner part and the sliding part are in a state of not being separated.

[0069] S520: Remove the first inner liner portion from the second inner liner portion.

[0070] As in this example, the second liner includes two substantially symmetrical liner parts. The first liner part can be removed from the second liner part in any reasonable manner, such as sliding outward, lifting upward, etc.

[0071] Obviously, when the structural forms and relative positions of the multiple liner parts change, the removal method and sequence of the liner parts can be flexibly adjusted according to actual needs.

[0072] S530: remove the second inner container portion in the second inner container from the second sliding structure of the sliding portion.

[0073] For example, the second liner portion can be removed from the second sliding structure in a reasonable manner based on the specific form of the first / second matching feature. For example, since the first liner portion has been removed, there is sufficient space above it, so an upward lifting method can be used. In addition, if the sliding portion is a structure that can directly release the constraint, the second liner portion should be removed from the first liner.

[0074] S540: After cleaning the second inner pot outside the oven, push the second inner pot into the first inner pot.

[0075] For example, the sliding connection between the first and second inner pots can be established gradually by following the same steps as described above for removal. That is, first, the second inner pot portion is mounted on the second sliding structure, then the first inner pot portion is mounted on the second inner pot portion, and finally, the second inner pot is pushed into the first inner pot. Obviously, the first and second inner pot portions can also be assembled outside the oven, and then the assembled first / second inner pot portions can be mounted on the second sliding structure.

[0076] At this point, the cleaning of the oven's inner tank assembly is basically complete. After removing the second inner tank, you can observe the cleanliness of the first inner tank, sliding parts, and other structures. If necessary, clean the corresponding parts by manual wiping or other methods.

[0077] For example, it can be cleaned directly in the sink, or with the help of a pre-configured cleaning device such as a dishwasher. A cleaning device can also be configured specifically for the oven. For example, the cleaning device can be flexibly placed or fixed in a specific target location. For example, since both inner pots have a fixed spatial shape, a separate cleaning device would often take up a large amount of space. Therefore, the following options are available:

[0078] (1) The user can clean it in a sink, with the help of a dishwasher, or in any other way he chooses.

[0079] (2) The oven is equipped with a cleaning device, which can be provided in the kitchen space in a pull-out manner (or mechanically connected and / or signal-connected to the oven).

[0080] (3) The manufacturer has cleaning equipment. Since the frequency of cleaning of the oven is low, the first / second liner unit can be cleaned by the manufacturer through centralized cleaning (such as providing cleaning services) or by maintenance personnel bringing cleaning equipment to provide door-to-door service.

[0081] As can be seen, in a preferred embodiment of the present application, the oven's inner liner assembly includes a first inner liner and a second inner liner. The second inner liner blocks the first inner liner, thereby ensuring the cleanliness of the frame and the first inner liner. Based on this, by removing the second inner liner from the first inner liner and then cleaning it separately outside the oven, it is expected that the oven will be kept clean. By configuring the second inner liner to include multiple inner liner sections, the space required for cleaning is reduced. As in this example, by integrally molding the multiple sections, the efficiency of quick removal is improved.

[0082] It should be noted that although the above embodiments describe the various steps in a specific order, those skilled in the art will appreciate that, in order to achieve the effects of the present application, the different steps do not necessarily need to be performed in this order; they can be performed simultaneously or in another order, and certain steps can be added, replaced, or omitted. For example, if space permits, the first liner portion can be removed from the second liner portion after the second liner portion is freed from the sliding portion; if the first / second liner portion includes multiple sub-portions, further quick-release operations can be performed; etc.

[0083] It should be noted that although the above-described oven cleaning method is described as an example, those skilled in the art will appreciate that the present application is not limited thereto. In fact, the user can flexibly adjust the relevant steps according to the actual application scenario, such as removing the first inner pot portion from the second inner pot portion by pulling upward or sliding.

[0084] Thus far, the technical solutions of the present application have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present application.
