[0029] This invention provides a method, device, rice cooker, and storage medium for maintaining the inner pot of a rice cooker, which solves the problem of rust on the cast iron inner pot of existing rice cookers. By generating oil mist through an atomizing oil spraying component and spraying it onto the inner pot, an automatic maintenance function is achieved to prevent the inner pot from rusting.

[0030] To address the aforementioned problem of rust on cast iron inner liners, this invention transforms manual oiling into automatic, even, and low-pressure oiling. Specifically, an oil box is installed in the base, and an atomizing oil sprayer is installed on the top cover. The oil box and the atomizing oil sprayer are connected by an oil pipe. When preset maintenance conditions are met, the atomizing oil sprayer starts working, drawing oil from the oil box, atomizing it, and spraying it onto the inner liner. This achieves automatic oiling maintenance, eliminating the need for manual oiling by the user, thus preventing rust and extending the service life of the inner liner.

[0031] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0032] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the rice cooker provided in an embodiment of the present invention. Figure 1 As shown, the rice cooker includes: a base 1, a top cover 2, and an inner pot 3. The inner pot 3 is placed in the base 1, and the top cover 2 is placed on the base 1. The rice cooker also includes: an oil storage component 4, an oil pipe 5, and an atomizing oil spray component 6. The oil storage component 4 is installed on the base 1; one end of the oil pipe 5 is connected to the oil storage component 4; the atomizing oil spray component 6 is installed on the top cover 2 and faces the top of the inner pot 3. The atomizing oil spray component 6 is also connected to the other end of the oil pipe 5. The atomizing oil spray component 6 is used to generate oil mist and spray it onto the inner pot 3.

[0033] Specifically, the base 1 has an inner cavity for accommodating the inner pot 3, which is placed within the cavity. The base 1 can be circular or rectangular in shape. A control panel is also provided on the base 1, with corresponding buttons for selecting the rice cooker's operating mode. This may include a button for automatic maintenance. When the user presses this button, the rice cooker controls the atomizing oil sprayer 6 to spray oil mist. It is understood that this control panel could also be located on the top cover 2; this is not a limitation.

[0034] The top cover 2 is fitted onto the base 1, sealing the inner cavity of the base 1 when the rice cooker is working, thus keeping the rice warm. There are several ways to connect the top cover 2 to the base 1. For example, the top cover 2 can be rotatably connected to the base 1, with the top cover 2 rotating and fitting onto the base 1; the top cover 2 can also be snapped onto the base 1, allowing it to separate from the base 1, and then snapping back onto the base 1 when the rice cooker is working; of course, other connection methods are also possible, which are not limited here.

[0035] The oil reservoir 4 stores rust-preventive liquid used to maintain the inner liner 3 and prevent it from rusting. This rust-preventive liquid can be commonly used cooking oil, which is easy to clean after maintenance and does not affect health. The oil reservoir 4 can be an oil box with corresponding scale lines and corresponding oil level warning lines. When the oil level is below the warning line, it indicates that the oil level is insufficient, reminding the user to add cooking oil.

[0036] The oil pipe 5 is generally a flexible hose. Part of the hose is housed in the base 1, and one end of the hose extends into the oil reservoir 4 to draw cooking oil. The other part of the hose is housed in the top cover 2, and the other end of the hose is connected to the atomizing spray nozzle 6. During operation, the hose draws oil from the oil reservoir 4 and flows along the hose to supply the atomizing spray nozzle 6.

[0037] The atomizing oil spraying component 6 is specifically installed in the center of the top cover 2. Spraying oil mist from the center of the top cover 2 allows for more even distribution, forming a uniform oil film on the surface of the inner liner 3, thus covering the entire inner surface of the inner liner 3 without missing any portion of the inner wall. The atomizing oil spraying component 6 can be an atomizing core, whose function is to atomize the extracted cooking oil into a mist and then spray it out. Of course, it is understood that the atomizing oil spraying component 6 can also have other structures; whatever its structure, as long as it achieves the atomization and spraying function, is acceptable. No specific structure is limited here.

[0038] In this embodiment, by adding an oil storage component 4, an oil pipe 5, and an atomizing oil spray component 6, the oil storage component 4 is installed on the base 1, the atomizing oil spray component 6 is installed on the top cover 2, and the two ends of the oil pipe 5 are connected to the oil storage component 4 and the atomizing oil spray component 6 respectively. The atomizing oil spray component 6 sprays the oil in the oil storage component 4 toward the inner liner 3, thereby achieving automatic maintenance of the inner liner 3, preventing the inner liner 3 from rusting, eliminating the need for manual application and maintenance by the user, and improving the user experience.

[0039] In one embodiment, to facilitate the user's addition of cooking oil, the base 1 is provided with a mounting portion. One side of the mounting portion is open to the outside of the base 1, and the oil storage component 4 is detachably housed in the mounting portion from the open side. Specifically, the mounting portion can be a slot formed on the base 1, located on the rear side of the base 1, facing outwards. A corresponding mounting structure, such as a sleeve or a slot, is provided within the slot; no limitation is made here. The oil storage component 4 is detachably connected to the base 1 through this mounting structure. During installation, the oil storage component 4 is inserted into the slot from the outside of the base 1; during disassembly, the oil storage component 4 is removed from the slot and taken out of the base 1. This detachable installation of the oil storage component 4 to the base 1 allows the user to easily remove the oil storage component 4 to add cooking oil, avoiding situations where oil is insufficient.

[0040] In this embodiment, the rice cooker also includes an oil storage cover 7, which is detachably connected to the base 1 to cover the open side of the mounting portion. Specifically, the shape and size of the oil storage cover 7 match the open side of the mounting portion, which can be understood as matching the shape and size of the slot. Thus, when the oil storage cover 7 is closed on the slot, it can completely seal the slot, preventing external dust from entering. The oil storage cover 7 and the base 1 are provided with corresponding connecting structures, such as snap-fit ​​slots, so that the oil storage cover 7 can be fastened to the slot of the base 1. When the oil storage cover 7 is closed on the slot, the surface of the oil storage cover 7 is flush with the surface of the base 1, which is neat and aesthetically pleasing.

[0041] Furthermore, to facilitate users' easy monitoring of oil levels, the oil reservoir cap 7 may be partially or entirely transparent. For example, the oil reservoir cap 7 may be made of a transparent material, making it completely transparent; alternatively, a portion of the oil reservoir cap 7 may be transparent, such as a portion made of glass, with the transparent portion corresponding to the scale lines on the oil reservoir 4. This allows users to observe the scale lines through the transparent portion and determine whether cooking oil needs to be added.

[0042] In one embodiment, the rice cooker further includes a heating element 8, which is mounted on the base 1 and is used to heat the inner pot 3. Specifically, the heating element 8 can be a heating plate located at the bottom of the inner pot 3. Before the atomizing oil sprayer 6 sprays oil onto the inner pot 3, the heating plate heats the inner pot 3 first, quickly and automatically drying any residual moisture or humidity on the inner pot 3 to avoid affecting the maintenance effect. In addition, a temperature sensor is also provided at the bottom of the inner pot 3 to detect the temperature of the inner pot 3. When the heating plate heats the inner pot 3 to a certain temperature, the heating plate stops heating.

[0043] Reference Figure 3 As shown, this embodiment of the invention also provides a method for caring for the inner pot of a rice cooker, wherein the rice cooker can be the rice cooker described in the above embodiment. Figure 3 The flowchart of a method for caring for the inner pot of a rice cooker provided in an embodiment of the present invention includes steps S110-S120.

[0044] S110. If the preset nursing conditions are detected, control the heating element to heat the inner liner;

[0045] S120. If the inner liner is detected to have reached a preset temperature, control the atomizing oil spraying component to generate oil mist and spray it toward the inner liner.

[0046] In this embodiment, the preset care conditions refer to the trigger conditions for entering the maintenance mode. These trigger conditions can be triggered by a button, for example, a one-button maintenance function on the control panel; pressing this button triggers the fulfillment of the preset care conditions. The trigger conditions can also be timed, such as triggering at 3 PM every Monday. They can also be remotely triggered via a mobile terminal, i.e., controlled by the user through a mobile app. Other preset care conditions are also possible and are not limited here. The preset temperature can be, for example, 45 degrees Celsius, or any other temperature, as long as it can quickly dry the moisture in the inner tank. The temperature of the inner tank is detected by a temperature sensor.

[0047] The specific working principle is as follows: When preset care conditions are met, a control signal is triggered to the rice cooker's controller. The controller first activates the heating element to heat the inner pot, quickly drying the moisture and humidity inside, ensuring the inner pot is dry. A temperature sensor continuously monitors the temperature of the inner pot, and when the temperature reaches the preset temperature, the heating element stops heating. Then, the atomizing oil sprayer draws cooking oil from the oil reservoir through an oil pipe. The atomizing oil sprayer atomizes the oil into a mist and sprays it towards the inner pot. The spraying time controls whether the atomizing oil sprayer stops spraying; the spraying time can be, for example, one minute, or any other time, and is not limited here. Thus, by meeting the preset care conditions, the automatic maintenance mode is triggered, which automatically sprays oil mist onto the inner pot. There is no need to apply it manually. Instead, the oil is automatically sprayed after drying through the atomizing oil spraying device inside the rice cooker, achieving the function of one-button automatic maintenance. Moreover, the oil atomizing device forms a uniform oil film with a stable oil volume, which will not contaminate other parts of the rice cooker, making it convenient for rice cooker users to maintain the cast iron pot for a long time and prevent it from rusting.

[0048] In one embodiment, reference is made to Figure 4 The nursing method further includes steps S131-S132.

[0049] S131. Detect whether the oil level in the oil reservoir is lower than the preset oil level threshold.

[0050] S132. If the oil level in the oil storage device is lower than the preset oil level threshold, a warning signal is generated.

[0051] In this embodiment, the oil level in the oil reservoir can be detected by a level sensor or a photoelectric sensor, or other detection elements, which are not limited here. The preset oil level threshold is consistent with the warning line of the oil reservoir, for example, it can be 10ml. When the detected oil level is lower than the preset oil level threshold, a corresponding warning signal is generated. This warning signal can be indicated by an indicator light, an icon displayed on a screen, or a buzzer alarm, which are not limited here.

[0052] To further illustrate the care method for the inner pot of the rice cooker in this embodiment, the following describes the care process for the inner pot of the rice cooker from the user's perspective.

[0053] After cooking, allow the cast iron pot to cool to room temperature. Use a sponge or similar cleaning tool with hot water to clean the inner pot. After cleaning, wipe the inner and outer walls of the inner pot with a cleaning cloth to remove water stains. Place the inner pot back into the rice cooker base, close the rice cooker lid, and visually check if the oil level in the oil reservoir is below the lower mark. If the oil level is below the lower mark, open the base oil reservoir cover, remove the oil reservoir, add oil to the upper mark, and reinstall the oil reservoir onto the rice cooker base, then close the base oil reservoir cover. If the oil level is visually above the lower mark, skip the above oiling steps and directly activate the care button. The internal oil pipe draws a measured amount of oil to the oil atomizer, and the heating element starts working simultaneously to heat the inner pot. The temperature sensor at the bottom of the inner pot detects the temperature. When the temperature reaches the preset temperature, the inner pot is fully heated. The oil spraying device then starts working, spraying oil mist from the top center of the inner pot. The care process ends when the preset spraying time is reached. Since the sprayed oil mist is made of edible oil, users can choose to clean the oil stains before the next cooking session; if the interval between cleaning and the next cooking session is within 24 hours, they can cook directly without affecting health and safety.
