Description

Technical Field

[0001] This application relates to the field of cleaning technology for kitchen appliances, specifically providing a cooking device and its cleaning apparatus. Background Technology

[0002] With the diversification of kitchen appliances, cooking equipment such as steam ovens, ovens, steam-grill combos, and steam-grill-fry combos have emerged on the market, enabling food to be cooked without human intervention. Taking steam-grill combos as an example, the inner cavity of the steam-grill combo needs to be cleaned regularly, mainly due to the types of food (such as chicken wings) and the cooking methods (such as roasting and tender roasting).

[0003] Currently, oven cleaning mechanisms are typically integrated into steam ovens. This is often achieved through a top-mounted cleaning module that connects to the oven's internal components, such as the clean water tank, waste water tank, heating elements, and piping. However, introducing an automatic cleaning function increases the overall complexity of the steam oven. Consequently, ensuring sufficient space for the arrangement of these components and maintaining the reliability of the automatic cleaning function may require adjustments to the existing structure, placement, and model of the steam oven. Therefore, there is still room for improvement in how to achieve oven cleaning without significantly impacting the overall design of the steam oven (excluding the automatic cleaning function). Summary of the Invention

[0004] This application aims to solve, at least to some extent, the aforementioned technical problems and / or at least a portion of them. Specifically, it addresses how to perform cleaning operations on cooking equipment without significantly affecting its configuration.

[0005] In a first aspect, this application provides a cooking device comprising: a cooking body including an inner pot having a cooking chamber; wherein a first water storage area is provided at the bottom of the inner pot, and a cleaning device is disposed in the inner pot at a position corresponding to the first water storage area, and at least a portion thereof is removably disposed in the inner pot.

[0006] This configuration allows for effective cleaning of the inner pot. Since the cleaning device of this application is almost independent of other structures of the cooking equipment (such as those related to basic cooking functions), it has minimal impact on the structural form of the cooking equipment. After cleaning, all or most of the cleaning device can be removed from the cooking equipment. This allows the cleaning device to be configured as a separate module within the cooking equipment.

[0007] Based on this, the performance of the cooking equipment can be guaranteed even without cleaning. In such cases, a fully modular automatic cleaning function is implemented. Users can choose to configure or not configure the automatic cleaning function when purchasing. Alternatively, the manufacturer can configure the automatic cleaning function. Users can also schedule a specialized agency or after-sales service personnel to perform automatic cleaning of the cooking equipment (e.g., door-to-door service, door-to-door pickup-centralized cleaning-door delivery, etc.).

[0008] It is understandable that the structure, cleaning principle, number, and placement / method of the cleaning device within the inner pot can be flexibly selected. Furthermore, some or all of the cleaning device can be removed according to actual needs. For example, in the case of a completely external cleaning device, it does not constitute a completely independent structure; it needs to cooperate with the existing structure of the cooking equipment to form a module capable of performing the cleaning function.

[0009] In one possible implementation of the above-mentioned cleaning device, the cleaning device includes: a water collection structure having a second water storage area; a cleaning assembly including a first power mechanism and a cleaning end, wherein the first power mechanism is capable of drawing water from the second water storage area to the cleaning end and distributing water to the inner wall of the inner tank through the cleaning end; and a second power mechanism capable of drawing water from the first water storage area to the second water storage area.

[0010] It is understandable that those skilled in the art can determine the structural form, location, and formation method of the first / second water storage area according to actual needs. For example, the first water storage area can be directly formed by pressing at the bottom of the inner tank, or a structure can be added to the bottom of the inner tank. This structure has a first water storage area with a certain liquid level. For example, the first water storage area can be formed by any structure with water collection function, such as an arc surface, a conical surface, or a frustum.

[0011] The second water storage area can be formed by a water collection structure with water-gathering function, such as a cylindrical structure or a box-shaped structure. For example, the outer wall of the water collection structure is roughly cylindrical, and the inner wall is roughly an inverted conical surface / frustum.

[0012] In one possible implementation of the cleaning device described above, the second power mechanism is firstly connected to the first water storage area, and secondly connected to at least the second water storage area; wherein the highest liquid level in the second water storage area is higher than that in the first water storage area.

[0013] This configuration allows for the reliable execution of the cleaning function by raising the liquid level.

[0014] In one possible implementation of the cleaning device described above, the first water storage area has a communication structure that enables communication with the outside of the cooking device; and / or the second power mechanism is also capable of communicating with the outside of the cooking device.

[0015] This design helps to avoid phenomena such as water overflowing from the bottom of the inner tank due to water accumulation in the shallower first water storage area.

[0016] Obviously, when the cooking appliance is open, the bottom of the inner pot must be able to connect with the outside, allowing water to overflow smoothly. The phrase "the first water storage area is able to connect with the outside of the cooking appliance" should be understood as: the ability to systematically discharge water to the outside of the cooking appliance. This could include, but is not limited to: adding a pressure-type structure with a collecting and guiding function to the bottom of the inner pot to directly lead water to the outside or discharge it to the outside via a wastewater pipe; or discharging water by adding connecting paths, pipes, or other structures.

[0017] Specifically, regarding the statement that "the second power mechanism can also communicate with the outside of the cooking equipment," the structure connecting the second power mechanism to the outside of the cooking equipment and the aforementioned structure connecting to the second water storage area can be relatively independent structures, or they can be integrated to at least a certain extent. For example, the integration method may include, but is not limited to: installing a switching mechanism such as a solenoid valve on a pipeline containing two branches; and adding a switching mechanism between the second power mechanism and two external outlets capable of delivering water to the second water storage area and the cooking equipment respectively, such as switching the communication mode of the second power mechanism through rotation, extension, or other movements of the switching mechanism.

[0018] In one possible implementation of the cleaning device described above, the water collection structure is removably disposed within the inner liner; and / or the water collection structure is capable of communicating with the outside of the cooking device.

[0019] This configuration ensures the performance of the cleaning device.

[0020] The water collection structure can be removed directly from the inner tank, allowing the collected water to be poured out directly. Alternatively, the water collected by the water collection structure can be discharged to the outside of the cooking appliance via a connecting pipe. It can be discharged directly or through a connecting structure such as an inner tank waste water drain pipe.

[0021] In one possible implementation of the above-mentioned cleaning device, the first power mechanism and / or the second power mechanism are fixedly installed on the water collection structure; or the water collection structure is detachably installed on the cleaning device.

[0022] This configuration provides possible assembly forms for the water collection structure relative to the first / second power mechanism. Taking a detachable arrangement of the water collection structure as an example, since the collected wastewater needs to be emptied after each cleaning cycle, the reliability of the first / second power mechanism can be ensured by this detachable arrangement. The water collection structure can be detachably connected to the cleaning device using any reasonable method such as snap-fit, sliding connection, or rotating connection.

[0023] In one possible implementation of the cleaning device described above, the cleaning device includes a carrier, the first power mechanism and / or the second power mechanism are disposed on the carrier, and the water collection structure is detachably disposed on the carrier.

[0024] This configuration ensures the performance of the cleaning device. The carrier can be any suitable structural form, such as a support, plate, or mounting base. The water collection structure can be removed from the carrier by means of rotation or pulling. The first / second power mechanism can be connected to the water collection structure simultaneously, or they can establish a connection corresponding to water transfer solely through their respective connections to the carrier.

[0025] In one possible implementation of the cleaning device described above, the cleaning device includes a detection component that is at least capable of detecting the water level data of the second water storage area.

[0026] With this configuration, it is possible to control the activation status and motion parameters of the aforementioned first / second power mechanism using water level data.

[0027] In one possible implementation of the cleaning device described above, the detection component includes: an image detection component disposed in the inner pot of the cooking device; and / or a liquid level detection component disposed at a position of the cleaning device corresponding to the second water storage area.

[0028] For example, the image detection component could be a camera module integrated into the cooking equipment (such as products containing an AI-powered sensor). The AI-powered sensor primarily monitors the cooking process in real-time to ensure the performance of the cooking equipment. When cleaning the inner tank of the cooking equipment, water level data can be detected. For instance, the liquid level detection component could be two liquid level sensors (high and low level sensors) located in the second water storage area. When the water level drops to the height corresponding to the low level sensor, the second power mechanism is activated. When the water level reaches the height corresponding to the high level sensor, the first power mechanism is activated.

[0029] In a second aspect, this application also provides a cooking apparatus equipped with a cleaning device for the cooking apparatus described in any of the preceding claims.

[0030] It is understandable that this cooking device has all the technical effects of the cleaning device of the aforementioned cooking device, which will not be repeated here. Attached Figure Description

[0044] The preferred embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this application and are not intended to limit the scope of protection of this application. For example, although this embodiment is described in conjunction with a steam oven / grill combo and a cleaning device including a water collection structure and cleaning components, it is obvious that those skilled in the art can flexibly adjust the type of cooking equipment. For instance, the cooking equipment can also be any possible cooking equipment such as a steam oven, oven, steam-grill-fry combo, or a small appliance such as a microwave-steam-grill combo. For small appliances, configuring a cleaning function itself is somewhat difficult; an external cleaning device can ensure the performance of the small appliance itself. Furthermore, any structural form capable of cleaning sealed inner chamber devices can be used as the cleaning device of this application. For example, the cleaning device can be an integrated structure or a split structure; the cleaning device can use a fixed / moving spray method; the water can be pressurized / heated by means of the cleaning device itself / the existing structure of the cooking equipment / the external structure of the cooking equipment; the cleaning device can use a cleaning method combining high-pressure spray and low-pressure fluid, etc.

[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. These are used 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 application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "installation," "setup," 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 application according to the specific circumstances.

[0047] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can still be implemented without certain specific details. In some examples, the structure and principles of steam ovens well-known to those skilled in the art are not described in detail, in order to highlight the main points of this application.

[0048] Main reference Figure 1 and Figure 2In one possible implementation, the steam oven mainly includes a cooking body, which comprises a housing 1 and an inner cavity 2 disposed within the housing. The inner cavity forms a cooking chamber capable of holding food to be cooked. For example, the inner cavity may have a shelf, on which food can be placed directly or in containers (such as plates) placed on the shelf. The inner cavity is equipped with a cleaning device 3, which can clean the inner wall of the inner cavity, the baking tray, the baking rack, the inside of the door assembly, etc. The cleaning device can be fixed to the inner cavity in a removable manner. The cleaning device can be configured with a separate battery pack or an external power source to ensure its operation. If an external power source is used, the plug should be waterproofed.

[0049] In this way, it is possible to clean the steam oven without affecting its existing structure as much as possible. Typical application scenarios include cleaning ovens, steam ovens and other cooking equipment of various models using the cleaning device. This is suitable for users (families) who own multiple sealed inner pot cooking equipment, or for service organizations / platforms that provide centralized cleaning services for cooking equipment.

[0050] Taking user-configured settings as an example, a cleaning device can be purchased along with the steam oven, or the cleaning function can be added to the steam oven by purchasing a separate cleaning device after the purchase is completed.

[0051] In one possible implementation, the inner liner molding 21 at the bottom of the inner liner 2 forms a first water storage area 201. This first water storage area has a certain depth and can store a certain amount of water. The inner liner molding can be a trough-shaped structure, an arc-shaped / prismatic water-gathering structure with the outer edge concave towards the center, or a structure with water storage function in any reasonable local area (such as a local area near the center, a certain side, etc.). In this example, the inner liner molding is part of the inner liner itself (integrated with the inner liner). Alternatively, a structure such as a disc-shaped structure or a shallow cylindrical structure can be added to the bottom of the inner liner for installation. This can be achieved by connecting with the existing structure of the steam oven, vacuum adsorption, magnetic adsorption, etc., and fixing it relative to the steam oven. It can be directly fixed to the steam oven, or fixed to a structure outside the steam oven (such as a nearby structure, the ground, etc.).

[0052] In one possible implementation, the cleaning device 3 includes a water collection structure 31, a cleaning component 32, and a second power mechanism 33. The water collection structure 31 forms a second water storage area 301, and the highest water level (sufficient to meet the operating conditions of the cleaning component) in the second water storage area is higher than that in the first water storage area. The cleaning component can spray water from the second water storage area (e.g., clean water or a mixture containing detergent or other auxiliary media) onto the inner wall of the inner liner. Taking the aforementioned inner liner molding as an example, the inner liner molding is typically shallow and has a large coverage area. Compared to the actual amount of water it can collect, the water level is too low (e.g., about 5mm), therefore, it cannot meet the operating conditions of the cleaning component (the water needs to be at a certain height). In this application, the second power mechanism can pump water from the first water storage area to the second water storage area, thereby meeting the operating conditions of the cleaning component. In this way, by reshaping the height of the water body, the water body can be superficially disconnected (such as compared to the structure of the pipeline circulation, or the stage when the water pump is not running, etc.) but in fact (such as from the perspective of the sustainability of cleaning), it can be continued. In this way, the inner tank can be cleaned with a certain amount of water.

[0053] In this example, the water collection structure is a box-shaped structure, and the second power mechanism 33 includes a water collection pump, which is disposed on the water collection structure. The inlet and outlet sides of the water collection pump are connected to the first and second water storage areas, respectively. The water collection pump can be a small water collection pump or any reasonable form of water collection pump, regardless of size, that can transfer a small amount of water at a low water level (such as a shallow inner tank pressure type). In this example, the water collection pump is a self-priming small water pump disposed approximately vertically on the outer wall of the water collection structure. The suction port of the small water pump is approximately located at the lowest position (area) of the inner tank pressure type. The suction port of the small water pump is connected to the second water storage area through a pipeline.

[0054] Obviously, those skilled in the art can determine the structural form of the water collecting pump, its configuration as a cleaning device, and its connection method with the first / second water storage area according to actual needs. For example, corresponding guiding / water-gathering structures can be set on the inlet / outlet sides to ensure reliable communication. The water collecting pump can also be set in, for example, the inner liner of a steam oven, the exterior of a steam oven fixed relative to the inner liner, or a structure that constitutes a cleaning device and mainly serves as a mounting carrier. Exemplarily, the carrier includes a frame or support, with a mounting position for the water collecting pump on the carrier. If a carrier is included, the water collecting structure can be fixed or detachably installed on the cleaning device. Exemplarily, the water collecting structure can be installed on the frame in a horizontal or vertical pull-out manner.

[0055] In one possible implementation, the cleaning assembly 32 includes a first power mechanism 321 and a cleaning end 322. The first power mechanism draws water from the second water storage area to the cleaning end, and then distributes the water to the inner wall of the inner tank through the cleaning end. In this example, the second power mechanism is a spray pump, and the cleaning end is a spray arm with multiple spray holes. The water pressure generated by the spray pump impacts the rotation of the spray arm, thereby evenly spraying the water onto the inner wall of the inner tank. If a sufficiently dense water jet can be provided, water spraying can also be achieved by keeping the cleaning end stationary or moving it slightly.

[0056] In one possible implementation, the cleaning end can be fixedly or detachably connected to the first power mechanism. Taking detachability as an example, multiple cleaning ends can be configured to better meet the cleaning needs of the steam oven. Besides the spray arm, the cleaning end can also be any reasonable structural form, such as a spherical structure or a combination of arms of multiple heights. Taking a combination of arms of multiple heights as an example, in addition to the cleaning end being detachable from the first power mechanism, it can also be internally detachable. For example, by disassembling one arm or replacing it with an arm of a different structure, the spraying effect of the cleaning end can be adjusted.

[0057] In this example, water in the first water storage area can be transferred to the second water storage area via a water collection pump to participate in the cleaning cycle. To ensure the reliability of the cleaning device, the first water storage area and / or the water collection pump can be configured to be connected to the outside of the steam oven. If excessive water accumulation occurs in the inner liner during the cleaning process (e.g., excessive water volume, high maximum liquid level of water containing foam affecting user experience, etc.), connecting the first water storage area to the outside of the steam oven can eliminate this phenomenon to a certain extent, thereby ensuring the continuity of the cleaning operation.

[0058] The first water storage area can be connected to the outside of the steam oven via an inner tank waste water recovery pipe or a separate connection structure such as a pipe / trough. By configuring the water collection pump to connect to the outside of the steam oven, in situations where the water volume in the second water storage area is greater than the water volume that the first water storage area needs to release (cannot hold), the water can be discharged to the outside of the steam oven to ensure the sustainability of the cleaning operation. The water collection pump can be connected to the second water storage area using the same or a different connection structure to directly discharge water to the outside of the steam oven, or the corresponding water outlet can be connected to the inner tank waste water recovery pipe to discharge excess water to the outside of the steam oven.

[0059] In one possible implementation, the steam oven includes structures related to its steaming function. The steaming function works by supplying high-temperature steam to the inner chamber containing the food. In this steam-filled environment, parameters such as steam temperature, steam volume, and cooking time are adjusted to complete the cooking process. The structures related to the steaming function of the steam oven mainly include a steam generator, a clean water tank, and a wastewater tank, all related to steam distribution and water recycling. For example, the clean water tank primarily supplies clean water to the steam generator, which heats the water to produce steam. Depending on the cooking requirements, steam is released into the cooking chamber, allowing the food to be cooked via pure steaming. After cooking, excess water is drained into the wastewater tank. The structure, number, and location of the steam generator, clean water tank, and wastewater tank can be flexibly selected according to actual needs. For instance, the clean water tank can be replenished manually or directly from an external water purifier. Furthermore, some of these structures can be integrated into the steam oven.

[0060] In one possible implementation, the steam oven includes structures related to the baking function. The baking function operates by providing circulating hot airflow to the cooking chamber containing the food, thus enabling cooking via hot air baking. Cooking can be performed solely by hot airflow, with steam also introduced (e.g., in a tender baking mode). The structures related to the baking function of the steam oven typically include a temperature-regulating fan (which guides the airflow to form a hot air stream), hot air heating components (such as a heating coil, primarily used to heat the air near the temperature-regulating fan), and a fan shroud assembly (forming a hot air chamber that houses the fan and heating coil, and is equipped with an air inlet and an air outlet that communicate with the cooking chamber to form a circulating airflow). Clearly, the specific structural form of these structures and their configuration within the steam oven can be flexibly adjusted according to actual needs.

[0061] In one possible implementation, the steam oven is equipped with heating elements and a heat dissipation assembly. Heating elements, such as heating tubes, are located at the top, sides, and bottom of the inner cavity. These heating elements can provide primary / secondary heating to the food during cooking. The heat dissipation assembly mainly includes a cooling fan and cooling ducts. The heat dissipation assembly is typically located at the top of the inner cavity. Under the action of the cooling fan, gas flows through the cooling ducts and is exhausted to the outside of the steam oven, thus dissipating heat from the top area.

[0062] In one possible implementation, the cleaning device includes a liquid level detection component. For example, the cleaning device may have a pair of liquid level detection components corresponding to high and low liquid levels at a location corresponding to the second water storage area, such as a first liquid level detection component 341 and a second liquid level detection component 342, exemplarily, where the (first and second) liquid level detection components are water level sensors. Based on this, in a specific example, the cleaning device performs its cleaning operation on the steam oven as follows: When a certain amount of water (e.g., a mixture of water and detergent, manually or automatically added with reference to the highest liquid level) is added to the water collection device, the user is reminded to close the door. The spray pump is then activated, thereby spraying the detergent-containing mixture onto the inner wall of the inner tank through the rotation of the spray arm. When the water level reaches the lowest level, the water collection pump is activated (e.g., the spray pump can be stopped or its operating parameters adjusted) so that, when the water level in the water collection structure rises, water is sprayed onto the inner wall of the inner tank through the spray arm. After the cleaning operation is completed, the water collection pump can be run to draw as much water as possible into the water collection structure, thereby improving the user experience (eliminating the need for the user to remove the water from the inner tank).

[0063] Obviously, those skilled in the art can adjust the parameters and startup logic of the above cleaning process according to actual needs. This adjustment may include, but is not limited to: the water collection pump starting to replenish water to the second water storage area before the water level reaches the minimum level, thus ensuring the continuity of the cleaning operation (preventing excessive water accumulation in the first water storage area and preventing the first power mechanism from malfunctioning); the initial water addition may be done only to the water collection structure or to the first water storage area; the initial water volume, the startup timing / operating parameters of the spray pump / water collection pump, etc., can be flexibly adjusted according to actual needs. For example, after a set water addition time, the water collection pump is started and operated intermittently.

[0064] Furthermore, the control logic based on the aforementioned pair of liquid level detection components is merely an exemplary description. For instance, image detection components such as cameras, which are already configured in the steam oven or the cleaning device, can also detect the water distribution and adjust the water volume and operating parameters of the first / second power mechanism based on the detection results to achieve cleaning of the steam oven. Additionally, the cleaning effect can be optimized by activating the heating components and steam generator. Moreover, the performance of the cleaning device can be optimized by adding a heating module.

[0065] As can be seen, in the preferred embodiment of this application, by configuring a cleaning device for the cooking equipment, the cleaning operation of the inner pot can be completed without affecting the structure of the cooking equipment as much as possible. That is, by externalizing the structure related to the cleaning function of the cooking equipment, the complexity of the cooking equipment is reduced, the cost is significantly reduced, and space is left for core functions such as steaming and baking. With the setting of the second power mechanism, water circulation can be achieved simply by using the inner pot pressing structure at the bottom of the inner pot or by adding a shallow pressing structure at the bottom of the inner pot. For example, in a specific example, a water circulation system based on a low water level (inner pot pressing) is constructed by the cooperation of a large pump (for spraying water) and a small pump (for collecting water). The water collection device, on the one hand, ensures the operational reliability of the first power mechanism by cooperating with the second power mechanism, and on the other hand, improves the user experience by collecting the water that allows for a single cycle.

[0066] The technical solutions of this application have 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 scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, 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 scope of protection of this application.
