Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen electrical equipment, in particular to a cooking equipment and a cleaning method thereof. BACKGROUND

[0002] With the development of household appliance technology, currently, cooking equipment capable of meeting the diversified and refined cooking requirements of users has appeared, such as cooking equipment using one or more cooking methods such as steaming, baking, and frying to cook food. Taking baking as an example, the product form of the corresponding cooking equipment can be a single / double cavity oven that has only baking as the cooking method, or can be an integrated machine such as a steaming-baking integrated machine or a steaming-baking-frying integrated machine that contains baking as the cooking method.

[0003] Among them, the cooking principle of using baking as the cooking method to cook food is to provide circulating hot air flow to the inner container (cooking chamber) where the food to be cooked is located, and to complete the cooking of the food by hot air baking. The cooking principle of using steaming as the cooking method to cook food is to provide high-temperature steam to the inner container where the food to be cooked is located, and to complete the cooking of the food by pure steaming. For example, there is also a cooking method that combines steaming and baking (such as tender baking mode).

[0004] Taking the oven (using baking as the cooking method) as an example, and taking chicken, goose, and mutton as examples of food to be cooked, since such food usually contains oil and water, during the cooking (heating) process, it is inevitable that oil / oil stains / oil residues will splatter / drip / fall onto the top / side / bottom walls of the inner container (as well as the inner wall of the door body). Accordingly, in order to ensure the use performance and user experience of the cooking equipment, the oven needs to be cleaned in a timely manner. In the current cleaning method, high-temperature pyrolysis steam cleaning generally has poor cleaning effect, so its acceptance is not high. The cleaning effect of the wipe / rinse type 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 the problems including but not limited to complicated / convenient operation, incomplete cleaning of all / partial areas, and certain operation difficulty for users. SUMMARY

[0005] The present application aims to at least partially solve the above technical problems and / or at least part of the above technical problems, specifically, how to improve the cleaning effect of the cooking equipment, and under this premise, to improve the user experience as much as possible.

[0006] In a first aspect, the present application provides a cooking apparatus, comprising: the cooking apparatus comprises a cabinet and a liner assembly arranged in the cabinet, the liner assembly comprises: a first liner; and a second liner arranged in the first liner in a pullable manner; wherein, the second liner comprises a frame and a fixed part and a movable part arranged in the frame, the movable part comprises at least one liner monomer, at least part of the liner monomer can be arranged in the frame in a detachable manner.

[0007] Through such a configuration, it is possible to clean at least part of the liner monomer of the movable part from the frame after the cooking apparatus is cleaned outside. On this basis, it is expected to improve the cleaning effect of the cooking apparatus.

[0008] It can be understood that those skilled in the art can determine the structure of the fixed / movable part, the number of components contained therein, the relative position of each component in the fixed / movable part, the relative position between the fixed part and the movable part, and the specific manner of arranging the frame. For example, the fixed part can be connected in an irreversible manner such as one-piece molding, welding, etc., which is not easy to disassemble and thus does not have to be disassembled during cleaning.

[0009] For the above-mentioned cooking apparatus, in a possible implementation, the movable part comprises a top plate, the top plate can be removed from the frame, and the second liner is arranged in the first liner in a pullable and non-detachable manner.

[0010] Through such a configuration, it is possible to clean the top plate outside the cooking apparatus after the top plate is removed, and to clean other parts in the area where the oven is located by using a manual wiping method.

[0011] For the above-mentioned cooking apparatus, in a possible implementation, the movable part comprises a top plate and a back plate, the top plate and the back plate can be removed from the frame, and the second liner is arranged in the first liner in a pullable and non-detachable manner.

[0012] Through such a configuration, it is possible to clean the top plate and the back plate outside the cooking apparatus after the top plate and the back plate are removed, and to clean other parts in the area where the oven is located by using a manual wiping method. When the cooking apparatus is cleaned using this scheme, after the top plate and the back plate are removed, in the case where the second liner is completely pulled out, all surfaces can be clearly displayed and are in a state convenient for operation. Moreover, in the case where the liner is not completely pulled out, a better cleaning effect can also be obtained. For example, it is more suitable for the case where the back plate is seriously contaminated and the space where the cooking apparatus is installed is limited.

[0013] For the cooking apparatus, in a possible implementation, the inner liner monomer comprises a plurality of subparts, at least one of the plurality of subparts being removably arranged to other parts of the inner liner monomer or to the frame.

[0014] For the cooking apparatus, in a possible implementation, the inner liner monomer comprises a plurality of subparts that are spliced; or the inner liner monomer comprises at least two subparts that are arranged in a stack, at least one of the subparts being removably arranged to the frame.

[0015] For the cooking apparatus, in a possible implementation, the frame comprises a first subframe and a second subframe, the first subframe and the second subframe being relatively telescopically arranged to form the frame.

[0016] In a second aspect, the present application provides a cooking apparatus, comprising a cabinet and an inner liner assembly arranged in the cabinet, the inner liner assembly comprising: a first inner liner; and a second inner liner arranged in the first inner liner in a manner that is pullable and detachable from the first inner liner; wherein the second inner liner comprises a frame and at least one inner liner monomer arranged in the frame.

[0017] By such an arrangement, the second inner liner can be removed as a whole from the first inner liner, and cleaned outside the cooking apparatus.

[0018] In a third aspect, the present application provides a cleaning method for a cooking apparatus, the cleaning method comprising: in a case where the second inner liner is pulled out from the first inner liner but not detached from the first inner liner, removing the top plate from the frame, so as to clean the top plate outside the cooking apparatus.

[0019] In the cleaning of the cooking apparatus by using the above-mentioned scheme, after the top plate is removed, in the case where the second inner liner is pulled out, all surfaces can be clearly displayed and are in a state that is convenient for operation. In this way, the disassembly and assembly steps are simple, the degree of contamination can be comprehensively known, and the cleaning of each part is more convenient. This is more suitable for a user group that is relatively not willing to accept (excessive) disassembly operations.

[0020] In a fourth aspect, the present application provides a cleaning method for a cooking apparatus, the cleaning method comprising: in a case where the second inner liner is pulled out from the first inner liner but not detached from the first inner liner, removing the top plate and the back plate from the frame, so as to clean the top plate and the back plate outside the cooking apparatus.

[0021] When the cooking device is cleaned by using the scheme, after the top plate and the back plate are removed, all surfaces can be clearly displayed in the case that the second inner container is completely pulled out, and are in a state convenient for operation. Moreover, in the case that the inner container is not completely pulled out, a better cleaning effect can also be obtained. For example, it is more suitable for the case that the back plate is seriously dirty and the space for installing the cooking device is limited.

[0022] In a fifth aspect, the application provides a cleaning method of a cooking device, the cleaning method comprising: pulling out and separating the second inner container from the first inner container, so as to clean the second inner container outside the cooking device; wherein the cleaning of the second inner container outside the cooking device comprises: cleaning the entire inner container; or removing at least part of the inner container monomers from the frame, so as to clean the removed inner container monomers.

Those skilled in the art can understand the specific meaning of the above terms in the present application according to the specific circumstances.

[0045] In addition, in order to better illustrate the present application, numerous specific details are set forth in the following detailed description, but one skilled in the art will understand that the present application can be practiced without certain specific details. In some instances, well-known structures of ovens, cooking principles / processes / parameters of roasting, etc. are not described in detail in order to avoid obscuring the present application.

[0046] The present application will be described below with reference to the accompanying drawings, in which: Figures 1 to 5

[0047] Referring primarily to Figures 1 to 4 In one possible embodiment, the oven 100 mainly comprises a cooking body 1, which comprises a cabinet 1 and an inner liner assembly 2, wherein the inner liner assembly comprises a first inner liner 21 arranged in the cabinet and a second inner liner 22 arranged in the first inner liner, the second inner liner forms a cooking chamber, and the second inner liner is arranged in the first inner liner in a pullable manner.

[0048] In one possible embodiment, the second inner liner 22 comprises a frame 221 and one or more inner liner monomers arranged on the frame, at least part of the inner liner monomers are arranged on the frame in a removable manner. As in the present example, the inner liner monomers comprise a top plate 222, a first side plate 223 and a second side plate 224 on the left and right sides, a back plate 225 (which can also be referred to as a fan cover in the present example), and a bottom plate 226. In each inner liner monomer, the part fixedly arranged on the frame is referred to as a fixed part, and the part removable from the frame is referred to as a movable part. For example, one or more of the top plate, the first / second side plate, the back plate, and the bottom plate are fixedly arranged (not removable) or integrally formed on the frame, at this time, the part can be understood as a fixed part.

[0049] For example, one or more of the top plate, the first / second side plate, the back plate, and the bottom plate can comprise a plurality of subparts, wherein part of the plurality of subparts are fixedly arranged or integrally formed on the frame, and the plurality of subparts of the inner liner monomer can be connected to form the corresponding inner liner monomer by splicing (such as direct butt joint, splicing by means of a carrier (a plate-shaped structure, a support frame, a frame, etc.), layering (such as partial overlap / total overlap, two-layer / more-layer stacking), etc.), or the like. For example, in the case of stacking, the inner layer can be removed for cleaning.

[0050] For example, the frame can be a whole (fixedly connected or integrally formed) structure, or a combination of a plurality of subframes, such as a plurality of subframes forming the frame in an assembled state. In the case of cleaning the inner liner assembly, the plurality of subframes can move relative to each other to facilitate removal of the inner liner monomers. For example, ​

[0051] (1) The frame comprises a first sub-frame (similar to the current frame) and a second sub-frame (an auxiliary frame inside the first sub-frame), and the second sub-frame is telescopic relative to the first sub-frame in the front-back direction. In this case, the second sub-frame can be completely accommodated in the first sub-frame. Based on such a configuration, when the inner container assembly needs to be cleaned, the second sub-frame can be moved forward relative to the first sub-frame, so that the operation position of the back plate removed from the frame can be moved forward, which can avoid interference with positions such as the operation panel of the oven.

[0052] (2) The frame comprises 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) which are telescopically connected in the front-back direction, and in this case, the two sub-frames can be spliced to form the frame. Based on such a configuration, when the inner container assembly needs to be cleaned, the operation position of the back plate can be moved 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 container body is removed (such as the inner container body being clamped between the two sub-frames) or the operation position of the inner container body is moved forward (such as the inner container body being arranged in the second sub-frame).

[0053] Therefore, by removing one or more movable parts from the frame, the user can conveniently clean the inner container body removed from the frame outside the oven in a manner such as placing it in a dishwasher, manually cleaning it in a sink, a target position specially used for cleaning the inner container body, etc.

[0054] It can be understood that those skilled in the art can flexibly select the specific manner of arranging each inner container body in the frame in a removable manner and the corresponding manner / direction / specific operation manner of 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 container body from the frame: pulling up, pulling sideways, tilting, and turning over.

[0055] In a possible implementation, the liner assembly includes a sliding part 23, which includes a first sliding structure arranged on the first liner and a second sliding structure arranged on the second liner. In the present example, the first sliding structure includes a pair of sliding rails arranged at the approximate middle of the first / second side plate. Correspondingly, another pair of sliding rails as the second sliding structure is arranged at the corresponding position of the two side plates of the first liner. Obviously, those skilled in the art can determine the structure form, number and arrangement position of the first / second sliding structure according to actual needs. For example, the first / second sliding structure can be located at the position where the bottom of the liner assembly meets the side, and any structure form of sliding rail can be selected, or other structure form of sliding connection pair can be selected. For example, in addition to arranging the sliding rail at the middle of the first / second side plate, a pulley can also be installed at the bottom of the second liner to ensure the convenience and stability of the sliding process.

[0056] In a possible implementation, the oven further includes a door assembly 3 arranged on the side of the cooking main body facing the operator (for example, the front side), for example, the door assembly can be arranged on the cooking main body in a flipable, pushable or pullable manner. For example, the flipable manner can be the axial up / down flip along the horizontal direction, or the axial left / right flip along the vertical direction. For example, the door assembly 3 is arranged on the cooking main body in a downward flipable manner, and a handle is arranged on the door assembly 3 for user operation.

[0057] In a possible implementation, the oven includes an illumination assembly, for example, the illumination assembly includes at least one illumination part 41. In the present application, the illumination part 41 is arranged on the first liner, and the second liner is provided with a light-transmitting structure 42 at the position corresponding to the illumination part. In this way, the light generated by the illumination part can reach the inside of the cooking cavity through the light-transmitting structure, thereby realizing the visualization of cooking. For example, in the present example, one illumination part is arranged on each of the left and right sides of the first liner, and the front and back positions of the illumination parts on the left and right sides are approximately the same but the heights are different. Correspondingly, the light-transmitting structure is arranged at the corresponding position of the first side plate 223 and the second side plate 224, for example, the light-transmitting structure can be a high-temperature-resistant glass arranged on the first / second side plate.

[0058] In a possible implementation, a shelf 51 (such as a grill or the like) is arranged in the cooking chamber of the oven, and the food to be cooked can be directly placed on the shelf or placed in a container (such as a tray or the like) placed on the shelf. In this case, one or more shelves can be arranged in the cooking chamber, or the shelves can be arranged at one or more positions in the cooking chamber. For example, a plurality of mounting positions 52 are arranged on the inner wall of the second inner container in the height direction, and the mounting positions are formed by the strip-shaped protrusions (such as shelves) on the inner sides of the side plates. The shelf can be arranged at any one of the mounting positions. Apparently, this is only an example, and those skilled in the art can determine the specific structure, number, and formation of the mounting positions according to actual needs. For example, a structure such as a support can be arranged inside the second inner container, and the mounting positions can be formed on or arranged on the support. A structure capable of fixing the shelf can be arranged on the door assembly, and the structure can be used as the mounting position alone or in combination with the structure inside the second inner container. In addition, the mounting position can be a stud (a plurality of studs) with a clamping groove, a sliding rail, or any other reasonable structure. In the case where the mounting positions include a plurality of mounting positions, the structure of the plurality of mounting positions and the way in which the shelf is arranged at different mounting positions can be the same or different.

[0059] In a possible implementation, since the implementation of the roasting cooking mode needs to be completed by means of the hot air flow as the cooking medium, the oven includes structures related to the generation and circulation of the hot air flow. For example, the oven includes a uniform temperature fan and a heating coil, etc. The uniform temperature fan is mainly used to make the temperature of the hot air flow delivered into the cooking chamber as uniform as possible, and the heating component is mainly used to heat the cooking medium to ensure that the temperature of the hot air flow meets the cooking requirements. For example, the uniform temperature fan and the heating component are located at the rear side of the back plate. In this way, under the action of the uniform temperature fan, the air in the cooking chamber is sucked into the hot air chamber at the rear side of the back plate through the return air port 61, heated by the heating component to become the hot air flow carrying heat as the cooking medium, and then thrown by the uniform temperature fan to the outer peripheral air supply port 62 and thus into the inner container again. In this way, the hot air flow (the temperature, flow rate, etc. of the hot air flow correspond to the cooking mode) can be delivered to the surface of the food to be cooked, so that the food to be cooked is cooked in the hot air roasting mode.

[0060] Based on the above structure, the present application also provides a possible cleaning method of the oven, which is mainly used to remove at least part of the inner container monomers (and the frame) from the oven in a quick-release manner, and then clean them in an external space.

[0061] Example 1

[0062] Reference is mainly made to Figure 3In the present example, the fixed part of each inner container monomer includes the first / second side plate, the back plate and the bottom plate, and the movable part includes the top plate. The cleaning method of the oven mainly includes the following steps:

[0063] S310, pulling the second inner container out of the first inner container.

[0064] As in the present example, the second inner container is pulled out to a position that can ensure that the second inner container does not separate from the first inner container and does not interfere with the removal of the top plate from the frame. The separation mentioned here should be understood as the frame not separating from the first inner container. As the frame can slide relative to the first inner container but not separate from the first inner container, this can be achieved by selecting a reasonable slide rail assembly.

[0065] S320, removing the top plate from the frame in the inner container monomer.

[0066] The top plate can be removed from the frame in a diagonal upward pulling, horizontal pulling or the like.

[0067] S330, cleaning the top plate removed from the frame outside the oven.

[0068] S340, cleaning the first / second side plate, back plate, bottom plate and the like provided on the frame in a scrubbing or the like manner without separating from the oven.

[0069] S350, installing the cleaned top plate to the frame. And after installation, push the second inner container into the first inner container.

[0070] The cleaning method shown in the example is suitable for the case where the overall disassembly will affect the field of view, operation convenience and the like to some extent, but the user is more resistant to the disassembly process.

[0071] Embodiment 2

[0072] Mainly refer to Figure 4 The present example is similar to Embodiment 2, except that in the present example, the fixed part of each inner container monomer includes the first / second side plate and the bottom plate, and the movable part includes the top plate and the back plate.

[0073] On the one hand, the back plate is arranged at a position relatively rearward compared to other inner container monomers. On the other hand, the hot air chamber formed behind the back plate belongs to the flow path of the hot air flow. Therefore, in the case of cleaning in place, the operation convenience may be improved compared to other parts, and there may be unobserved cleaning parts in the field of view. In view of this, the cleaning method of the present embodiment is proposed. Compared to Embodiment 1, the present example can significantly improve the cleaning effect of the oven at the premise of slightly increasing the disassembly workload.

[0074] Embodiment 3

[0075] Mainly refer toFigure 5 In one possible implementation, the cleaning method of the oven mainly includes the following steps:

[0076] S510, the second inner container is extracted from the first inner container and separated from the first inner container.

[0077] As the second sliding structure in the sliding part can still be fixedly connected with the frame, the sliding connection between the first sliding structure and the second sliding structure is released. Or the fixed connection between the frame and the second sliding structure in the sliding part is released.

[0078] S520, the second inner container is transferred to a target position outside the oven.

[0079] The target position can be a special operation table, or any kitchen countertop, tabletop, coffee table, ground, etc.

[0080] S530, at the target position, the top plate, the first / second side plate, the back plate and the bottom plate in the inner container monomer are removed from the frame. That is, the disassembly of the inner container monomer is performed outside the oven.

[0081] In this example, the top plate, the first / second side plate, the back plate and the bottom plate in each inner container monomer are movable parts. Obviously, part of them can also be changed to fixed parts.

[0082] S540, outside the oven, the inner container monomer removed from the frame is cleaned. And the frame can be cleaned in a way such as scrubbing according to the actual situation.

[0083] As for the aforementioned embodiments 1 to 3, for the inner container monomer that has been removed from the frame, it can be cleaned directly in the sink, or it can be cleaned by means of the cleaning equipment configured, such as the dishwasher, or a cleaning device can be specially configured for the oven. Exemplarily, since the inner container monomer is a larger sheet structure, a separate cleaning device often occupies a larger space. Therefore, the optional solutions include:

[0084] (1) The user can choose to clean it in the sink by means of the dishwasher.

[0085] (2) The oven is provided with a cleaning device, and the cleaning device can be set in the kitchen space (or mechanically connected and / or signal connected with the oven) in a drawable manner.

[0086] (3) The manufacturer has a cleaning device, since the cleaning frequency of the oven is low, the removed inner container monomer can be cleaned by the manufacturer's centralized cleaning (such as providing cleaning service) or the maintenance personnel carrying the cleaning device to provide on-site service.

[0087] S550, complete assembly and push the second liner into the first liner.

[0088] After the liner monomers are installed to the frame, the assembled second liner is assembled to the first liner, so as to complete the assembly. It is also possible to install part or all of the liner monomers to the frame after the frame is assembled with the first liner. That is, the order of installing the liner monomers to the frame can be flexibly adjusted.

[0089] At this point, the cleaning work of the liner assembly of the oven is basically completed. After the second liner is removed, the cleanliness of the structure of the first liner, the sliding part and the like which are not removed can be observed, and in the case of cleaning, the corresponding parts are cleaned by manual wiping or the like.

[0090] As can be seen, in the preferred embodiment of the present application, the liner assembly of the oven includes the first liner and the second liner, and the cleanliness of the first liner is ensured by the shielding of the second liner. Based on this, by removing at least part of the liner monomers from the frame and then cleaning them separately outside the oven, it is expected to ensure the cleaning effect of the oven, and any reasonable cleaning method can be flexibly used to clean the liner monomers. By pulling out the second liner from the first liner or detaching the second liner from the oven, the operability of the quick release is ensured. Among them, the specific structure of the liner monomers contained in the movable part, whether to separate the frame from the first liner, etc. can be selected according to actual needs, so as to ensure that the assembly difficulty is within the operable range of the user.

[0091] It should be noted that although the above embodiments describe the steps in a specific order, those skilled in the art can understand that in order to achieve the effect of the present application, the steps are not necessarily executed in this order, they can be executed simultaneously or in other order, or some steps can be added, replaced or omitted. For example, in the case of fixing the heating pipe to the top plate, a step of releasing the constraint between the heating pipe and the top plate is also required.

[0092] It should be noted that although the cleaning method of the oven constructed in the above specific manner is introduced as an example, those skilled in the art can understand that the present application should not be limited thereto. In fact, the user can flexibly adjust the related steps and the parameters in the steps, such as the structure of the liner monomers, the removable liner monomers, the specific disassembly method of the liner monomers, the number of subparts contained in each liner monomer, whether there is a subpart in the liner monomer that does not need to be disassembled, etc. can be flexibly selected according to actual needs.

[0093] So far, the technical solution of the present application has been described in combination with the preferred embodiments shown in the drawings, but it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the present application, and the technical solutions after the changes or replacements will all fall within the protection scope of the present application.
