Description

Technical Field

[0001] This invention relates to a fully automatic rice cooker device, capable of supplying, washing, and cooking ingredients such as rice or grains. Specifically, the fully automatic rice cooker device includes: a grain supply device for supplying ingredients stored in measured quantities; a washing device for washing the ingredients supplied by the grain supply device by rotating in both directions; and a cooking device for receiving the ingredients washed by the washing device and cooking them. Because the fully automatic rice cooker device can automatically complete the washing and cooking of ingredients, the number of parts is reduced, and hygiene is improved. Background Technology

[0002] Typically, when cooking, people take the required amount of rice from the rice bucket, rinse it several times in a container, pour it into a rice cooker or pressure cooker, add an appropriate amount of water according to the type of grain, and then heat it to complete the cooking process.

[0003] The existing cooking methods, besides using a rice cooker for heating and cooking, require manual labor for scooping and rinsing the rice, making them inconvenient for dual-income families, single individuals, the elderly, or children.

[0004] To overcome the above shortcomings, people have developed a variety of cooking devices that combine rice buckets and rice cookers. In recent years, a variety of automatic cooking devices have also been developed. These automatic cooking devices can supply rice in a measured amount. After the rice is washed by a washing device, the washed rice and water used for cooking are added to an electric rice cooker with a heating device. In other words, the rice supply, washing and cooking can be completed automatically.

[0005] However, existing automatic cooking devices have very complex structures, and when washing rice by means of rotating blades, the germ of the rice is easily washed away, destroying its nutritional components.

[0006] Furthermore, existing automatic cooking devices have pressure valves or valves for regulating water and ingredients on the lid or inner pot. These valves are not resistant to high temperatures and pressures and require frequent replacement or maintenance.

[0007] Furthermore, the rice containers used to store ingredients are not equipped with measures to prevent spoilage or suppress rice weevils, making it difficult to maintain the quality of the ingredients and thus ensuring the best taste of the rice.

[0008] In addition, existing automatic cooking devices are generally used in large-scale places such as schools and the military, and are not suitable for ordinary households.

[0009] To overcome the above deficiencies, the applicant invented and applied for Korean Patent No. 10-2048872 (application date: 2019.11.20) entitled "Fully Automatic Rice Cooker". This fully automatic rice cooker uses the washing bucket used for washing rice as the pot lid, so there is no need to set a valve for supplying water and grains on the pot lid, thereby simplifying the structure of the cooking device.

The equipment removes impurities from the grains; a cooking device (300) is located below the washing device (200), which receives the washed grains, contains them, seals them, and then heats and cooks them; a main frame (400) provides a frame for mounting and supporting the grain supply device (100), the washing device (200), and the cooking device (300), and connects components for ensuring the storage, supply, washing, and cooking of the grains; and a lifting mechanism (500) and a pipe (600).

[0084] The grain supply device (100) includes: a storage tank (110) for storing food inside and supplying the food to the washing device (200) through a grain outlet (114) located on the lower side; a grain meter (120) for measuring the type and amount of grain inside the storage tank (110) to ensure accurate measurement and mixing of multiple grains; and a tank tray (130) installed on the lower side of the storage tank (110) and rotating about a tray hinge (132) on one side as a central axis, so that the storage tank (110) can be pushed in and taken out.

[0085] The washing device (200) includes: a washing tub (210) that receives and washes the supplied ingredients through a feeding trough (211), and then rotates downward to supply the washed ingredients to the cooking device (300); blades (220) that rotate in both directions inside the washing tub (210) to remove impurities attached to the ingredients; and a washing tub bracket (230) that is located on the outside of the washing tub (210) and can be raised and lowered to a specific height during storage, washing, and cooking.

[0086] The cooking device (300) includes: an inner pot (310) for receiving and containing washed ingredients from the washing tub (210); a heating device (331) for heating the bottom of the inner pot (310) to achieve cooking; and a cooking device bracket (330) for mounting the heating device (331) and serving as a frame to support the inner pot (310).

[0087] The main frame (400) includes: a feeding guide device (410) disposed between the grain supply device (100) and the washing device (200) for guiding the food discharged from the storage tank (110) into the washing tank (210); a vacuum pump (413) for maintaining a vacuum pressure inside the storage tank (110); a sealing adapter (414) disposed between the washing device (200) and the cooking device (300), with its top flush with the outer periphery of the washing tank (210) and its bottom tightly connected to the edge (312) of the inner liner (310); and an electronic communication program that can control a series of operations such as storage, washing and cooking via a mobile device.

[0088] The lifting mechanism (500) is located on both sides of the main frame (400) and provides power to raise and lower the washing tub bracket (230) or the cooking device bracket (330).

[0089] The pipe (600) forms a pipeline that not only supplies purified washing water to the washing tub (210), but also allows for convenient use of the washing water discharged from the washing tub (210).

[0090] The fully automatic rice cooker device of the present invention stores ingredients in the storage bin (110) at the top. During cooking, the ingredients enter the washing bin (210) through the feeding guide device (410).

In this case, one of the compartments (112) is sealed and cannot be used to hold ingredients.

[0097] The storage container (110) is provided with a plate-shaped opening and closing plate (113) on its lower side. The opening and closing plate (113) can ensure that the storage container (110) with its open bottom is in a sealed state to prevent the food stored inside from being discharged.

[0098] The opening and closing plate (113) has teeth formed on its outer periphery, which can mesh with the opening / closing drive gear (116) provided on one side of the main frame (400), so that the opening and closing plate (113) can rotate.

[0099] A grain outlet (114) is formed on one side of the opening / closing plate (113) to discharge the food stored in the compartment (112). When the opening / closing plate (113) rotates under the drive of the opening / closing gear (116), the grain outlet (114) changes position with the rotation, moving from one compartment (112) to another, discharging the food stored in the corresponding compartment (112). The grain outlet (114) can be moved to the position of the compartment (112) containing the food to be discharged by means of the opening / closing gear (116).

[0100] In this way, the grains stored in a certain compartment (112) are discharged, achieving a quantitative supply. Even if each compartment (112) stores a single type of grain, the grain discharge port (114) can be moved to a compartment (112) containing a different type of grain to discharge the grain, so that the grains can be quantitatively mixed when cooking mixed grain rice.

[0101] Furthermore, the central portion of the opening and closing plate (113) is further formed with a central shaft insertion port (115), into which the pallet central shaft (131) of the bucket tray (130) is inserted.

[0102] The upper side of the storage bin (110) is provided with a grain meter (120) for measuring the grain in each compartment (112).

[0103] The grain meter (120) includes: a measurement identification module (122) for measuring the type and quantity of grain stored in each compartment (112); and a light (121) having a light-emitting device to facilitate accurate measurement by the measurement identification module (122).

[0104] The measurement and identification module (122) identifies the type of grain by capturing images of the grains stored in each compartment (112) and identifies the quantity by measuring the height, including at least one of a camera or sensor. Multiple measurement and identification modules (122) may be included and can be mounted on top of each compartment (112) to measure the type and quantity of grains stored in each compartment (112) at a fixed position. Alternatively, a single measurement and identification module (122) and a guide rail (123) that can move circumferentially to change the position of the single measurement and identification module (122) can be provided, enabling the measurement and identification module (122) to circulate along the guide rail (123) through each compartment (112) to measure the type and quantity of stored grains. In this embodiment, as... Figure 4 As shown in (b), a single measurement identification module (122) is configured to move along the guide rail (123).

[0105] Or, such as Figure 4 As shown in (a), the amount of grain in each compartment (112) of the storage bin (110) can be measured by a sensor (117) installed in each compartment (112). The sensor (117) is installed on each compartment (112) to measure the amount of grain, and one or more measurement identification modules (122) are installed on the top of the compartment (112) to identify the type of grain by means of the sensor (117) and the measurement identification module (122).

[0106] An illumination lamp (121) is provided as a means of illumination, enabling the measurement and identification module (122) to accurately photograph and measure the grains in each compartment (112). The illumination lamp (121) provides light, allowing the measurement and identification module (122) to obtain high-quality images when photographing and measuring the grains, thereby improving the accuracy of the measurements.

[0107] After the grain meter (120) captures images of the grains stored in each compartment (112) via the measurement and identification module (122), it performs calculations and compares the captured images with typical grain images stored in internal memory (not shown) or a server. By extracting the grains most similar to those captured by the measurement and identification module (122), the type of grain stored in the compartment (112) is identified.

[0108] The grain meter (120) identifies the type and amount of grain, and controls the rotation of the opening and closing plate (113) based on the identified information to control the type and amount of grain discharged, thereby quantitatively mixing multiple grains.

[0109] A sealing ring may also be provided on the lower edge that contacts the storage barrel (110) to seal the storage barrel (110) used for storing grain.

[0110] A bucket tray (130) can also be provided at the bottom of the storage bucket (110) to facilitate pushing in and taking out from the main frame (400).

[0111] When grain is added into the storage bin (110), the bin tray (130) guides the storage bin (110) out of the main frame (400) and supports the increased weight of the storage bin (110) after the grain is added. The bin tray (130) includes: a support plate (133) for supporting the bottom edge of the storage bin (110); a tray central axis (131) located at the center and inserted into and connected to the central axis insertion port (115) of the opening and closing plate (113); and a tray hinge (132) disposed on one side and rotating about the central axis.

[0112] The support plate (133) supports the storage bucket (110) at its edge, with its inner side open to facilitate the discharge of grain from the compartment box (112). A sealing ring can also be provided at the edge portion connected to the storage bucket (110) to enhance the seal.

[0113] The central axis (131) of the bucket tray (130) can be inserted into the central axis insertion port (115) formed on the opening and closing plate (113) to fix the storage bucket (110) on the bucket tray (130).

[0114] The tray hinge (132) is attached to one side of the main frame (400). The storage bin (110) rotates about the tray hinge (132) to be pushed in and taken out of the main frame (400) and to guide its movement path.

[0115] The bucket tray (130) serves as a support structure, supporting the increased weight when grain is added to the storage bucket (110), and also guiding the pushing and taking-out actions of the storage bucket (110).

[0116] Take out the storage bucket (110) through the bucket tray (130), add ingredients into it, use the grain meter (120) to measure the type and amount of grain stored inside and set the mixing ratio, and then control the opening and closing plate (113) to rotate according to the mixing ratio, so as to discharge the ingredients through the grain discharge port (114).

[0117] like Figure 3 As shown, the food discharged to the bottom first passes through the feeding guide device (410). The feeding guide device (410) is used to guide the food discharged from the grain supply device (100) through the feeding trough (211) of the washing device (200) into the washing device (200), and it is located between the grain supply device (100) and the washing device (200).

[0118] The feed guide device (410) is formed to tilt downward toward the feed trough (411). The food falling into the feed guide device (410) is guided to the open feed trough (411) and then falls into the feed trough (211) of the washing tub (210), and then enters the washing tub (210). The bottom of the feed trough (411) is formed to conform to the shape of the washing tub (210) or the rotary screen (236) described later.

[0119] Here, in order to reduce the overall height of the invention, the slope tilting inward and downward is only slightly greater than the horizontal plane. The feeding guide device (410) can be connected to a vibration motor (not shown) to help move the food through vibration, so that the food can be guided and discharged even at a small inclination. In addition, by reducing the inclination of the feeding guide device (410), the overall height of the invention is reduced, thereby reducing the product size.

[0120] In addition, such as Figure 3 As shown, a sealing adapter (414) is provided between the washing device (200) and the cooking device (300). The top of the sealing adapter (414) is shaped to conform to the shape of the washing tub (210) or the rotary sieve (236), thereby enabling a tight connection. The bottom of the sealing adapter (414) can be tightly connected to the edge (312) of the inner liner (310) for sealing. A steam outlet (415) is formed on one side, through which steam generated due to the increase in internal pressure of the inner liner (310) is discharged.

[0121] Figure 5 and Figure 6 This is a perspective view of the washing device in the fully automatic rice cooker according to the present invention.

[0122] like Figure 5 and Figure 6 As shown, the washing device (200) is located below the grain supply device (100) and washes the ingredients supplied by the grain supply device (100) before heating them in the cooking device (300). The washing device (200) includes: a washing bucket (210) that receives the supplied ingredients through a feeding trough (211), rotates downward after washing, and supplies the washed ingredients to the cooking device (300); blades (220) inside the washing bucket (210) that sweep away impurities attached to the ingredients by rotating in both directions; and a washing bucket bracket (230) located outside the washing bucket (210) that can be raised and lowered to a specific height during storage, washing, and cooking.

[0123] The washing tub (210) is used to wash ingredients. It supplies and discharges ingredients through a feeding trough (211) formed by opening one side, and holds ingredients and washing water in its hollow interior.

[0124] The washing tub (210) has washing tub central shafts (212) at both ends. The washing tub central shaft (212) located at the rear is connected to the washing tub drive gear (234) of the multi-stage motor (232) to receive the transmitted rotational driving force. The front side of the washing tub (210) has a washing tub inlet (214) for supplying washing water into the interior of the washing tub (210) and a washing tub drain (215) for discharging impurities and washing water after washing.

[0125] The washing tub hose (640) includes an inlet hose (641) connected to the inlet (214) of the washing tub and a drain hose (642) connected to the outlet (215) of the washing tub. The washing tub hose (640) is telescopic, so even if the washing tub (210) moves up and down or rotates, it can still maintain the connection and will not fall off.

[0126] The top of the washing tub (210) is formed with a washing tub drain pipe (213) that communicates with the washing tub inlet (214). The washing water is discharged into the interior of the washing tub (210) through multiple water distribution holes (213a) formed on the washing tub drain pipe (213).

[0127] The washing tub (210) is equipped with blades (220) for washing ingredients. The blades (220) consist of washing blades (221), scraper blades (222), and blade rotation shafts (223). The washing blades (221) have spacers to remove impurities attached to the ingredients. The scraper blades (222) are plate-shaped for easy cleaning of the ingredients. The washing blades (221) and the scraper blades (222) are fixed on the blade rotation shafts (223).

[0128] The blade rotation shaft (223) protrudes from the front or rear side of the washing tub (210) and is located inside the central shaft (212) of the washing tub. The blade rotation shaft (223) is hollow inside, and the washing water flows into the hollow interior and is then discharged outward through the water distribution hole (213a).

[0129] Water-dividing holes (213a) are also formed on the blade rotation shaft (223) and the scraper blade (222). The rinsing water flowing inside the hollow blade rotation shaft (223) is discharged through the water-dividing holes (213a), and when rinsing ingredients are supplied to the cooking device (300), the ingredients remaining inside the rinsing tub (210) and on the blades (220) can be cleaned.

[0130] The washing tub (210) receives the food ingredients supplied by the grain supply device (100) through the feed trough (211), and the washing tub drain pipe (213) or the water distribution holes (213a) formed on the blades (220) supply washing water. After the food ingredients and washing water enter the washing tub (210), the washing blades (221) rotate repeatedly in both directions to remove impurities attached to the food ingredients.

[0131] After rinsing, the rinsing tub (210) is rotated so that the feed trough (211) faces downwards, supplying ingredients and rinsing water to the cooking device (300). To ensure that the ingredients are discharged only from the upper part of the cooking device (300) through the feed trough (211), the scraper blades (222) are positioned inside the feed trough (211), and the rinsing tub (210) is not perpendicular to the feed trough (211) when rotating, to prevent the ingredients from spilling out. At this time, a vibration motor (not shown) is used to vibrate the rinsing tub (210) and the blades (222), causing all remaining ingredients in the rinsing tub (210) to fall into the cooking device (300) through vibration.

[0132] like Figure 6 As shown, a filter screen (216) is provided on one side of the washing tub (210) at a specific distance from the drain outlet (215) of the washing tub. The cross-sectional area of ​​the filter screen (216) is larger than that of the drain outlet (215) of the washing tub, so the flow rate that can pass directly through the filter screen at one time is much greater than the flow rate of a filter of the size of the drain outlet (215) of the washing tub.

[0133] The filter (216) only allows impurities removed from the food to be discharged with the rinsing water and prevents the food from leaking out of the drain (215) of the rinsing bucket.

[0134] If the filter is placed on the cross-section of the drain outlet (215) of the washing tub, the limited cross-section of the drain outlet (215) of the washing tub will cause the filtration of impurities and the flow rate of the washing water to slow down. Moreover, when a lot of impurities are attached to and accumulated on the filter, the permeable area of ​​the filter will become smaller, resulting in a significant reduction in drainage efficiency, thus extending the time required to complete cooking.

[0135] As a result, the rinsing water containing impurities after rinsing in the rinsing tub (210) stays in the rinsing tub (210) for a longer time, causing the impurities in the rinsing water to redeposit on the food, so the number of rinsing times needs to be increased, thereby reducing the rinsing efficiency.

[0136] Therefore, the present invention forms the area of ​​the filter screen (216) to be larger than the cross-sectional area of ​​the drain outlet (215) of the washing tub, thereby increasing the throughput of the filter screen (216) and accelerating the drainage speed.

[0137] Furthermore, the present invention also includes a filter chamber (217), which is a space formed by the filter screen (216) and the drain outlet (215) of the washing tub at a certain distance. The filter chamber (217) is the space through which the washing water passing through the filter screen (216) flows into the drain outlet (215) of the washing tub. Only the washing water that has had impurities removed by the filter screen (216) can flow into the filter chamber (217). A larger amount of water passes through the filter screen (216), which has a larger cross-sectional area than the drain outlet (215) of the washing tub. After the washing water that has had impurities removed by the filter screen (216) passes through the filter chamber (217), it is quickly discharged through the drain outlet (215) of the washing tub, which is not equipped with a filter.

[0138] The rinse water, after impurities have been removed, stays in the filter chamber (217) for a period of time, thereby forming a water depth greater than the diameter of the drain outlet (215) of the rinse bucket, which increases the flow rate of the rinse water flowing through the drain outlet (215) of the rinse bucket and also improves the drainage speed.

[0139] Therefore, the time that the rinsing water containing impurities coexists with the food is shorter, minimizing the amount of redeposition on the food, thereby reducing the amount of rinsing water and the number of rinsing cycles required, and improving rinsing efficiency.

[0140] Figure 7 A multi-stage motor of a fully automatic rice cooker device according to the present invention is shown.

[0141] like Figure 7 As shown, the central shaft (212) of the washing tub and the blade rotation shaft (223) are coaxial and rotate on the same shaft, with rotational force provided by a multi-stage motor (232) located behind the washing tub (210). In the multi-stage motor (232), the blade drive gear (233) is inserted into the hollow interior of the washing tub drive gear (234), and multiple motors (M) are provided for rotating the two gears.

[0142] The washing tub drive shaft (234a) extends from the washing tub drive gear (234), and the washing tub drive shaft (234a) and the washing tub center shaft (212) are connected by a mechanical structure such as a concave-convex joint.

[0143] A blade drive shaft (233a) extends from the blade drive gear (233) and is inserted into the hollow interior of the washing tub drive shaft (234a). The blade drive shaft (233a) and the blade rotation shaft (223) are connected by a mechanical structure such as a concave-convex joint.

[0144] The washing tub (210) and the blades (220) receive rotational force from a multi-stage motor (232) through a mechanical structure such as convex and concave parts. Through this connection, the washing tub (210) can move freely in the longitudinal direction and receive the transmitted rotational force when engaged.

[0145] Therefore, the washing tub (210) can be easily removed without complicated disassembly when it is taken out, and since it is not equipped with an electrical device, it can be safely washed with water.

[0146] The washing tub (210) has a vertically movable washing tub bracket (230) on its outer side. A multi-stage motor (232) for rotating the washing tub (210) and the blades (220) is provided on the rear side of the washing tub bracket (230). Lifting wings (235) with insertion ports (512) for the lifting mechanism (500) are formed on both sides. An internal base (231) for stable support is provided. In this invention, the base (231) can be replaced by any object with a supporting function, such as rollers, bearings, etc. The term "base (231)" is a general term encompassing such configurations.

[0147] In an embodiment of the present invention, the outer periphery of the washing tub (210) is supported by the base (231) of the washing tub bracket (230). When the washing tub bracket (230) is raised and lowered by the lifting mechanism (500), the washing tub (210) is also raised and lowered by the washing tub bracket (230).

[0148] Before the washing tank bracket (230) is raised and lowered, an initial height is formed between the bottom of the washing tank (210) and the feed guide device (410), and also between the top of the washing tank (210) and the sealing adapter (414). This height is defined as the first height.

[0149] The washing tub (210) washes the ingredients at the first height of the washing tub bracket (230). There is a gap between the bottom of the feeding guide device (410) and the top of the sealing adapter (414), so that the washing tub (210) can rotate smoothly in both directions without contact or friction.

[0150] Figures 8 to 10 It is a cross-sectional view of the rinsing device in operation during the cooking process.

[0151] like Figure 8 As shown, after rinsing the ingredients in the washing tub (210), the washing tub (210) is rotated so that the feeding trough (211) is positioned at the bottom, discharging the ingredients into the inner liner (310). Then, as... Figure 9As shown, the washing tub (210) rotates at a certain angle, so that the sealed outer periphery is tightly connected to the top of the sealing adapter (414). The cooking device (300) heats the inner pot (310) to start cooking, and the washing tub bracket (230) is lowered by the lifting mechanism (500), so that the washing tub (210) is tightly connected to the top of the sealing adapter (414), and the gap is eliminated. This height is defined as the second height, and the outer periphery of the washing tub (210) tightly connected to the top of the sealing adapter (414) is defined as the first outer periphery (218).

[0152] The washing tub (210) is tightly connected to the top of the sealing adapter (414), thereby sealing the top of the sealing adapter (414). Therefore, the washing tub (210) acts as a lid for the inner pot (310), which can increase the pressure inside the inner pot (310) during cooking.

[0153] The washing tub (210) serves as the lid of the inner liner (310). This design simplifies the structure and improves hygiene by cooking the washing tub (210) at high temperature from the bottom, evaporating any residual moisture inside, and disinfecting it.

[0154] like Figure 10 As shown, after cooking, the washing tub bracket (230) is raised by the lifting mechanism (500), so that the washing tub (210) is tightly connected to the bottom of the feeding guide device (410), thereby eliminating the gap between the washing tub (210) and the bottom of the feeding guide device (410). This height is defined as the third height, and the outer periphery of the washing tub (210) tightly connected to the bottom of the feeding guide device (410) is defined as the second outer periphery (219).

[0155] The grain supply device (100) is sealed to prevent outside air from entering. In addition, the vacuum pump (413) is activated to draw air from inside the grain supply device (100) through the vacuum suction port (412) to maintain a vacuum pressure inside.

[0156] Therefore, the risk of food spoilage stored in the grain supply device (100) is reduced, and pests such as rice weevils can be prevented from breeding in the food. By maintaining the optimal quality of the ingredients, more delicious rice can be cooked.

[0157] Furthermore, the first outer periphery (218) of the washing tub (210) at the top of the shielding sealing adapter (414) and the second outer periphery (219) of the washing tub (210) at the bottom of the shielding feeding guide device (410) are composed of different sides. The first outer periphery (218) used to seal the inner liner (310) will inevitably generate a large amount of moisture, which can easily cause food spoilage when it diffuses into the grain supply device (100). Therefore, by dividing the sealing outer periphery of the sealing adapter (414) and the feeding guide device (410) into a first outer periphery (218) and a second outer periphery (219) respectively, impurities that may appear in the grain supply device (100) and the cooking device (300) are prevented from entering, thereby improving hygiene.

[0158] In another embodiment of the invention, such as Figure 11 and Figure 12 As shown, the washing bucket bracket (230) of the washing device (200) may also include a rotary screen (236) that is tightly connected to the sealing adapter (414) and the feed guide device (410).

[0159] The rotary screen (236) is configured to rotate in the outer circumferential direction outside the washing tub (210). The rotary screen (236) can rotate and change position along the circumferential direction of the washing tub (210).

[0160] Furthermore, the rotary screen (236) has a closed closed surface (238) and an open open surface (237) along its length. An elongated hole (239a) is formed on the front side through which the central shaft (212) of the washing tub passes, and a hose through-hole (239) for the washing tub hose (640) is formed with a larger area than the elongated hole (239a). Even if the rotary screen (236) moves up and down and rotates through the elongated hole (239a) and the hose through-hole (239), the central shaft (212) of the washing tub and the washing tub hose (640) will not interfere with the rotary screen (236).

[0161] In other words, the front of the rotary screen (236) is open, so when the rotary screen (236) rotates, the central shaft (212) of the washing tub and the hose inlet (239) will not be blocked by any structure, thus preventing interference.

[0162] The base (231) of the washing tub bracket (230) supports the outer periphery of the rotary screen (236). The base motor (231a) rotates the base (231), thereby driving the rotary screen (236) to rotate.

[0163] The rotary screen (236) rises and falls together with the washing tub support (230) lifted by the lifting mechanism (500). When the washing tub support (230) is at the first height, the rotary screen (236) does not contact the sealing adapter (414) and the feed guide device (410).

[0164] When the washing tub bracket (230) is lowered to the second height by the lifting mechanism (500), the closed surface (238) of the rotary screen (236) is tightly connected to the top of the sealing adapter (414), and the inner liner (310) is sealed, thereby increasing the pressure during cooking.

[0165] When the washing bucket bracket (230) is raised to the third height by the lifting mechanism (500), the closed surface (238) of the rotary screen (236) is tightly connected to the bottom of the feed guide device (410), and the grain supply device (100) is sealed. At this time, when the rotary screen (236) moves up and down, the washing bucket (210) does not move with the washing bucket bracket (230), but is fixed at the first height.

[0166] Below, for reference Figure 13 The working process of the washing device (200) in the embodiment equipped with a rotary screen (236) is described.

[0167] like Figure 13 As shown in (a), the initial state is with the feed chute (211) facing upwards to facilitate receiving the supplied ingredients from the grain supply device (100). Therefore, the open surface (237) of the rotary screen (236) also faces upwards, and the washing tub support (230) remains in its initial position, i.e., at the first height, without raising or lowering. In this position, the rotary screen (236) forms gaps between the top of the sealing adapter (414) and the bottom of the feed guide device (410). Furthermore, since a gap is formed between the inner surface of the rotary screen (236) and the washing tub (210), the rotation of the washing tub (210) is undisturbed.

[0168] At this location, the ingredients are supplied from the grain supply device (100) to the washing tub (210) and washed inside it.

[0169] After rinsing, rotate the washing tank (210) so that the feed trough (211) of the washing tank (210) and the open surface (237) of the rotary screen (236) face downwards. Figure 13 (b) shows the feed chute (211) when it is in the horizontal direction when rotating downwards. Figure 13Figure (b) shows a diagram where the open face (237) is horizontal while the rotary screen (236) is also rotating. However, when the feed chute (211) of the washing tub (210) is horizontal during rotation, the rotary screen (236) can remain stationary so that the open face (237) is vertical. As the washing tub (210) rotates, the flexible hose (640) connected to the front of the washing tub is retractable, maintaining the connection during rotation. The flexible hose (640) moves along the path of the hose penetration (239).

[0170] like Figure 13 As shown in (c), the feed trough (211) and the open surface (237) are located below, so that the washed ingredients inside are poured out and discharged into the inner liner (310).

[0171] After excretion, such as Figure 13 As shown in (b), the washing tub (210) rotates so that the feed trough (211) is in a horizontal position, and the open surface (237) of the rotary screen (236) is also in a horizontal position. At this time, the closed surface (238) faces downward.

[0172] like Figure 13 As shown in (d), the lifting mechanism (500) lowers the washing tub bracket (230) to a second height. The rotary screen (236) also lowers, causing the sealing surface (238) to be tightly connected to the top of the sealing adapter (414), thereby sealing the inner liner (310). The outer periphery of the rotary screen (236) tightly connected to the top of the sealing adapter (414) is defined as the third outer periphery (238a). After the sealed inner liner (310) is heated, its internal pressure increases. At this time, the washing tub (210) is fixed at the first height, neither rising nor falling, and the top of the washing tub (210) can contact the inner surface of the rotary screen (236).

[0173] After cooking is complete, such as Figure 13 As shown in (b), the rinsing tub bracket (230) rises again to the first height. Besides the rinsing and cooking processes, as... Figure 13 As shown in (e), the lifting mechanism (500) raises the washing tub bracket (230) to a third height to ensure the safety of the food stored in the storage tub (110). At this time, the open surfaces (237) of the feed chute (211) and the rotary screen (236) are in a horizontal position, and the closed surface (238) of the rotary screen (236) faces upward. The washing tub (210) is fixed at the first height without rising or falling, and the bottom of the washing tub (210) can contact the inner surface of the rotary screen (236).

[0174] The bottom of the feed guide device (410) and the closed surface (238) of the rotary screen (236) are tightly connected, thereby sealing the storage tank (110) and isolating it from external air. At this time, the closed surface (238) of the rotary screen (236) that is tightly connected to the bottom of the feed guide device (410) is defined as the fourth outer periphery (238b).

[0175] Then, the vacuum pump (413) is started to draw air from the grain supply device (100) through the vacuum suction port (412) to maintain a vacuum pressure inside. Maintaining a vacuum pressure inside can prevent the breeding of pests such as rice weevils and minimize grain spoilage.

[0176] When the washing tub bracket (230) is at the first height, a gap is formed between the washing tub (210) and the rotary screen (236), which helps the washing tub (210) rotate smoothly and makes the open surface (237) of the rotary screen (236) located on the upper or lower side to achieve the supply and discharge of ingredients.

[0177] When the washing tub bracket (230) is at the second height, the closed surface (238) of the rotary screen (236) is tightly connected to the top of the sealing adapter (414), and the top of the washing tub (210) can contact the inner surface of the rotary screen (236). The inner liner (310) is sealed, thereby increasing the pressure during heating and cooking.

[0178] When the washing tub support (230) is at the third height, the closed surface (238) of the rotary screen (236) is tightly connected to the bottom of the feed guide device (410), and the bottom of the washing tub (210) can contact the inner surface of the rotary screen (236). The grain supply device (100) is sealed, thereby preventing the inflow of external air and ensuring the safe storage of food.

[0179] More efficient cooking is achieved by positioning the washing tub bracket (230) at different heights, and hygiene is further improved by dividing the outer periphery of the rotary screen (236) which is tightly connected to the sealing adapter (414) or the feed guide device (410) into a third outer periphery (238a) and a fourth outer periphery (238b).

[0180] The cooking device (300) receives the ingredients supplied by the washing device (200) for cooking. It is located below the washing device (200). The cooking device (300) includes: an inner pot (310) for receiving and containing the washed ingredients from the washing bucket (210); a heating device (331) for heating the bottom of the inner pot (310) to achieve cooking; and a cooking device bracket (330) for mounting the heating device (331) and serving as a frame to support the inner pot (310).

[0181] Figure 14 The inner pot of the circular cooking device in the fully automatic rice cooker apparatus according to the present invention is shown.

[0182] like Figure 14 As shown, in this invention, the inner liner (310) can be formed as a circle. A handle (311) is formed on one side of the circular inner liner (310), and a protrusion (312a) is formed on the top edge (312).

[0183] A heating device (331) is provided on a cooking appliance bracket (330) for accommodating a circular inner pot (310). The front of the cooking appliance bracket (330) is open to facilitate the insertion and removal of the inner pot (310). The heating device (331) has an inner pot lifting member (335) that is inclined to the rearward direction at its center. A protruding groove (333) is formed on the upper part of the cooking appliance bracket (330), into which the protrusion (312a) of the inner pot (310) is inserted and engaged. A locking rod (334) for rotating the protruding groove (333) is formed on the front side of the cooking appliance bracket (330).

[0184] When the inner pot (310) is inserted into the cooking appliance bracket (330), the inner pot lifting member (335) lifts the inner pot (310), and the protrusion (312a) of the edge (312) engages in the protrusion groove (333). By grasping and rotating the handle (311) of the inner pot (310) or moving the locking lever (334), the protrusion groove (333) engages with the protrusion (312a), thereby connecting the inner pot (310) and the cooking appliance bracket (330), so that the edge (312) of the inner pot (310) is tightly connected to the top of the cooking appliance bracket (330).

[0185] In addition, such as Figure 15 and Figure 16 As shown, the inner liner (310) of the present invention can also be formed in a square shape. The square inner liner (310) has handles (311) formed on both the front and rear sides.

[0186] A heating device (331) is provided on the cooking device bracket (330) for accommodating the square inner pot (310). The front of the cooking device bracket (330) is open to facilitate the insertion and removal of the inner pot (310). The upper part of the heating device (331) has a rearward-inclined rising track (338) to guide the insertion and removal of the inner pot (310). The sides of the cooking device bracket (330) are provided with rising cams (337) to raise the rising track (338), and the front of the cooking device bracket (330) is provided with a connecting rod (336) to press the rising cams (337) and rotate them upward.

[0187] like Figure 16As shown in (a), when the square inner pot (310) is pushed into the cooking appliance bracket (330) along the rising track (338), the edge (312) of the inner pot (310) contacts the top of the cooking appliance bracket (330). At this time, as... Figure 16 As shown in (b), pressing down on the connecting rod (336) causes the rising cam (337) to rotate upward, and the rising track (338) rises under the action of the rising cam (337), so that the entire edge (312) of the inner pot (310) is tightly connected to the top of the cooking device bracket (330).

[0188] Furthermore, in this invention, the cooking device (300) employs a height-adjustable structure. For example... Figure 17 As shown, handles (311) are formed on the front and back sides of the inner liner (310).

[0189] A door (322) is formed on the front side of the inner liner drawer (320) surrounding the inner liner (310), allowing the inner liner (310) to be held by hand for insertion or removal. Protruding surfaces (323) are formed on both side walls, which insert into sliding grooves (332) of the cooking appliance bracket (330). A handle groove (321) for placing the inner liner (310) is formed on the upper part of the inner liner drawer.

[0190] A heating element (331) is provided at the bottom of the cooking appliance bracket (330), and the front of the cooking appliance bracket (330) is open, allowing the inner pot (310) to be inserted and removed. The gaps formed between the side walls of the cooking appliance bracket and the heating element (331) form sliding grooves (332), allowing the protruding surface (323) of the inner pot drawer (320) to move in and out of these grooves. Lifting wings (235) extend from the side walls, and these lifting wings (235) are inserted into the lifting wing insertion port (512) of the lifting mechanism (500) to raise and lower the appliance.

[0191] After inserting the handle (311) of the inner pot (310) into the handle slot (321) of the inner pot drawer (320), insert the protruding surface (323) into the sliding slot (332) of the cooking device bracket (330) and push it in. At this time, the bottom surface of the inner pot (310) is on the heating device (331).

[0192] The ingredients rinsed by the rinsing device (200) enter the inner pot (310) to begin cooking. The lifting wing (235) is inserted into the lifting wing insertion port (512) of the lifting mechanism (500), and the cooking device bracket (330) is raised under the action of the lifting mechanism (500). The edge (312) of the inner pot (310) is tightly connected to the bottom of the sealing adapter (414), and the rinsing bucket bracket (230) descends to a second height and is tightly connected to the top of the sealing adapter (414), thereby sealing the inner pot (310).

[0193] The inner pot (310) and the heating device (331) are tightly connected and rise or fall together, so there is no gap, which improves heat conduction. Therefore, cooking efficiency is improved and cooking time is shortened.

[0194] Figure 18 This is a perspective view of the lifting mechanism in the fully automatic rice cooker device according to the present invention.

[0195] The lifting mechanism (500) is used to raise or lower the washing tub bracket (230) or the cooking device bracket (330), and includes a lifting frame (511) formed along the main frame (400) and movable up and down, a lifting wing insertion port (512) connected to the lifting frame (511) for inserting the lifting wing (235), and a lifting device for transmitting power to the lifting frame (511). The lifting device is driven by any one of a linear motor (517), a cylinder (516), and a screw (518).

[0196] like Figure 18 As shown in (a), in the lifting mechanism (500) driven by the cylinder (516) of the lifting device, it includes a movable slide (514) connected to the lifting frame (511) and a fixed slide (515) connected to the main frame (400).

[0197] When the cylinder (516) of the lifting device extends and pushes the movable slide (514), the movable slide (514) slides upward or downward along the inclined surface of the fixed slide (515). The lifting frame (511) connected to the movable slide (514) also moves upward or downward, thereby moving the lifting wing insertion port (512). Since the lifting wing (235) formed on the washing tub bracket (230) or cooking appliance bracket (330) is inserted into the lifting wing insertion port (512), the washing tub bracket (230) or cooking appliance bracket (330) also moves upward or downward.

[0198] The lifting elastic device (513) is an elastic device connecting the lifting frame (511) and the main frame (400). It provides elastic force to ensure that the inclined surfaces of the moving slide (514) and the fixed slide (515) remain in contact at all times. Even if the power of the lifting device is lost, the moving slide (514) and the fixed slide (515) can maintain their inclined surfaces in contact with each other under the action of the lifting elastic device (513).

[0199] like Figure 18As shown in (b), in the case of a lifting mechanism (500) driven by a linear motor (517), the lifting device of the linear motor (517) is connected to and combined with the lifting frame (511) and the main frame (400), and the lifting frame (511) is moved up or down by the operation of the linear motor (517). When the lifting frame (511) moves, the washing tub bracket (230) or cooking device bracket (330) into which the lifting wing (235) is inserted can move up and down.

[0200] like Figure 18 As shown in (c), in the case of a lifting mechanism (500) driven by a screw (518), the lifting device of the screw (518) is connected to and engaged with the lifting frame (511) and the main frame (400). When the screw (518) rotates, the lifting frame (511) moves up or down. When the lifting frame (511) moves, the washing tub bracket (230) or cooking device bracket (330) into which the lifting wing (235) is inserted can move up and down.

[0201] The lifting mechanism (500) raises the washing tub bracket (230) or cooking device bracket (330), thereby sealing the inner liner (310) and the storage tub (110).

[0202] Figure 19 and Figure 20 The piping of a fully automatic rice cooker device according to the present invention is shown.

[0203] like Figure 19 and Figure 20 As shown, the present invention also includes a pipe (600) for supplying washing water to the washing tub (210). The pipeline (600) includes: a water filter (610) for receiving and purifying tap water from the outside; a first valve (620) for controlling the rinsing water purified by the water filter (610) to flow into a water purifier faucet (630) and an inlet hose (641); a water purifier faucet (630) for discharging the rinsing water purified by the water filter (610); a drain tray (670) for containing the rinsing water discharged by the water purifier faucet (630); a rinsing tub hose (640) consisting of an inlet hose (641) for supplying rinsing water and a drain hose (642) for draining water; a drain pump (650) for controlling the rinsing water discharged from the rinsing tub (210); a discharge water storage tank (680) for storing the rinsing water discharged through the drain hose (642); and a second valve (660) for controlling the discharged rinsing water to flow into the discharge water storage tank (680) or a drain outlet.

[0204] First, tap water supplied from outside is received and delivered to a water filter (610). One or more water filters (610) may be installed. The rinse water purified by the water filter (610) flows through a first valve (620) to a water faucet (630) or an inlet hose (641) connected to the rinse tub inlet (214) of the rinse tub (210).

[0205] The rinse water flowing to the water purifier faucet (630) can be used for various purposes such as drinking, while the waste purified water (drinking water) is collected in the drain pan (670) and discharged to the outside.

[0206] The rinsing water flowing into the rinsing tub (210) is supplied with water for rinsing and cooking the food in the rinsing tub (210). After rinsing, the drain pump (650) is started and the water is discharged through the drain hose (642).

[0207] The rinsing water discharged from the rinsing bucket (210) can either flow directly to the discharge water storage tank (680) under the control of the second valve (660), or it can be discharged to the outside. The discharge water storage tank (680) is a water tank used to store the rinsing water after rinsing, and the stored rice rinsing water can be discharged through the tank outlet (681) so that it can be used independently. Alternatively, it can be drained to the outside through a separate pipe connected to the discharge water storage tank (680).

[0208] Furthermore, a wireless communication module (not shown) can be installed on one side of the fully automatic rice cooker device of the present invention. The wireless communication module (not shown) communicates with the user's smartphone and can send cooking or rinsing instructions through an application on the smartphone. The instructions received from the wireless communication module (not shown) are transmitted to the control module (not shown), which performs grain selection, cooking control, rinsing control, and rotation control of the rinsing tub (210).

[0209] The cooking process will now be described with reference to an embodiment of the fully automatic rice cooker apparatus according to the present invention. The washing device (200) with a rotary sieve (236) has been described previously and is therefore omitted.

[0210] Take out the storage bucket (110) and store the ingredients inside. When cooking is required, rotate the opening and closing plate (113) to discharge the ingredients in the compartment box (112) through the grain outlet (114). The ingredients enter the washing bucket (210) through the supply trough (411) of the feeding guide device (410) and the feeding trough (211) of the washing bucket (210).

[0211] At this time, the washing tub bracket (230) is at the first height. The washing water enters the washing tub (210) through the washing tub inlet (214), and the washing blades (221) rotate in both directions to remove impurities from the food.

[0212] After rinsing, the rinsing tub (210) rotates so that the feeding trough (211) faces downwards, and the ingredients and rinsing water are poured into the inner pot (310) of the cooking device (300). The scraper blade (222) rotates to sweep the remaining ingredients in the rinsing tub (210) into the inner pot (310).

[0213] The washing tub (210) is rotated at a certain angle so that the first outer periphery (218) faces downwards, and then lowered to a second height by the lifting mechanism (500), so that the first outer periphery (218) is tightly connected to the top of the sealing adapter (414). Furthermore, the cooking appliance bracket (330) is raised by the lifting mechanism (500), thereby tightly connecting the edge (312) of the inner pot (310) to the bottom of the sealing adapter (414). The inner pot (310) is heated in a sealed state by the heating device (331), causing the internal pressure to increase.

[0214] After cooking is completed, the cooking device bracket (330) is lowered, the tight connection between the edge (312) of the inner pot (310) and the bottom of the sealing adapter (414) is released, and the inner pot (310) can be taken out through the inner pot drawer (320). The washing bucket bracket (230) and the washing bucket (210) are raised together to the first height.

[0215] In addition to the rinsing and cooking processes, the rinsing bucket bracket (230) is raised to a third height to ensure the safety of the food stored in the storage bucket (110). The second outer periphery (219) of the rinsing bucket (210) is tightly connected to the bottom of the feed guide device (410), thereby sealing the grain supply device (100) so that external air cannot enter. By operating the vacuum pump (413), the inside of the grain supply device (100) is kept under vacuum pressure to prevent the growth of pests, thereby minimizing food spoilage.
