The opening and closing plate (113) can ensure that the storage barrel (110) with the open bottom is in a sealed state so as to prevent the food materials stored in the storage barrel from being discharged.

The opening and closing plate (113) has teeth formed on an outer circumference thereof, which are engaged with an opening/closing driving gear (116) provided at one side of the main body frame (400), so that the opening and closing plate (113) can be rotated.

A grain discharge port (114) is formed at one side of the opening and closing plate (113) so as to discharge the food material stored in the cell (112). When the opening and closing plate (113) rotates under the drive of the opening/closing driving gear (116), the position of the grain discharging port (114) changes along with the rotation, and the grain discharging port moves from one cell box (112) to the other cell box (112) to discharge food materials stored in the corresponding cell box (112). The grain discharge port (114) can be moved to a position of a cell (112) storing food material to be discharged by the on/off driving gear (116).

Thus, the grains stored in one of the cells (112) are discharged, and the quantitative supply is realized. Even if grains such as a single kind are stored in each of the cells (112), the grains can be discharged by moving the grain discharge port (114) to the cell (112) containing grains of different kinds, and the grains can be quantitatively mixed even when the coarse cereal is cooked.

In addition, a central shaft insertion hole (115) is further formed at the central portion of the opening and closing plate (113), into which a tray central shaft (131) of the tub tray (130) is inserted.

The upper side of the storage tub (110) is provided with a grain meter (120) for measuring grains in each of the cells (112).

The grain meter (120) includes: a measurement identification module (122) for measuring the type and amount of grain stored in each of the cells (112); and an illumination lamp (121), the illumination lamp (121) having a light emitting device so that the measurement identification module (122) can accurately measure.

The measurement identification module (122) identifies the category by taking an image of the grain stored in each bin (112) and the stock by measuring the height, including at least one of a camera or a sensor. The measurement identity module (122) may comprise a plurality of pieces, which may be mounted on top of each cell (112), measuring the grain type and quantity stored in each cell (112) at a fixed location. Alternatively, a single measurement identity module (122) and a rail (123) that can be moved in a circumferential direction to change the position of the single measurement identity module (122) may be provided, thereby enabling the measurement identity module (122) to be circulated along the rail (123) to each cell (112) to measure the type and amount of grain stored. In the present embodiment, as shown in fig. 4 (b), a state in which the single measurement identification module (122) is configured to be movable along the guide rail (123) is shown.

Alternatively, as shown in fig. 4 (a), the amount of grain in each cell (112) can be measured by a sensor (117) provided in each cell (112) of the storage tub (110). The sensor (117) is arranged on each cell (112) to grasp the quantity of the grains, one or more measurement identification modules (122) are arranged on the top of the cell (112), and the types of the grains are identified through the sensor (117) and the measurement identification modules (122).

An illumination lamp (121) is provided as an illumination means so that the measurement identification module (122) can accurately photograph and measure grains in each cell (112). The illumination lamp (121) irradiates light so that the measurement identification module (122) can obtain high-quality images when photographing and measuring grains, thereby improving the accuracy of measured values.

After the grain meter (120) captures the grain image stored in each of the cells (112) by the measurement identification module (122), a calculation process is performed to compare the captured image with a typical grain image stored in an internal memory (not shown) or a server. The grain type stored in the cell (112) is identified by extracting the grain most similar to the image taken by the measurement identification module (122).

The kinds and amounts of grains are recognized by the grain gauge (120), and the rotation of the opening plate (113) is controlled according to the recognized information to control the kinds and amounts of the discharged grains, thereby quantitatively mixing the various grains.

A sealing ring may be further provided on a lower edge contacting the storage tub (110) to seal the storage tub (110) for storing grains.

A tub tray (130) may be further provided at the bottom of the storage tub (110) to facilitate the pushing in and out of the main body frame (400).

The tub tray (130) guides the taking out of the tub (110) from the main body frame (400) when adding grains to the inside of the tub (110), and supports the increased weight of the tub (110) after adding grains, the tub tray (130) comprising: a support plate (133) for supporting a bottom edge of the storage tub (110); a tray center shaft (131) positioned at the center portion, and connected to the center shaft insertion port (115) of the opening/closing plate (113) by being inserted therein; and a tray hinge (132) provided at one side and rotated around the central axis.

The support plate (133) supports the storage tub (110) at an edge, and is opened at an inner side thereof to facilitate the discharge of grains in the cell (112). A sealing ring may be further provided at an edge portion connected to the storage tub (110) to enhance sealing.

The tray center shaft (131) of the tub tray (130) may be inserted into a center shaft insertion port (115) formed on the opening and closing plate (113), thereby fixing the storage tub (110) on the tub tray (130).

The tray hinge (132) is connected to one side of the main body frame (400). The storage tub (110) rotates around the tray hinge (132) to be pushed in and taken out from the main body frame (400) and to guide a moving path thereof.

The drum tray (130) serves as a supporting structure capable of supporting an increased weight when grains are added to the storage drum (110), and also guiding the pushing-in and pulling-out actions of the storage drum (110).

The storage tub (110) is taken out through the tub tray (130), food materials are added to the inside thereof, the kind and amount of grains stored in the inside are measured using the grain meter (120) and a mixing ratio is set, and then the opening plate (113) is controlled to rotate according to the mixing ratio, thereby discharging the food materials through the grain discharge port (114).

As shown in fig. 3, the food material discharged to the lower side first passes through the feed guide (410). The feeding guide device (410) is used for guiding food materials discharged from the grain feeding device (100) to enter the inside of the elutriation device (200) through the feeding groove (211) of the elutriation device (200), and is arranged between the grain feeding device (100) and the elutriation device (200).

The feed guide (410) is formed to be inclined downward toward the feed slot (411), and the food material dropped into the feed guide (410) is guided to the open feed slot (411) and then dropped into the feed slot (211) of the elutriation tub (210), and then enters the inside of the elutriation tub (210). The bottom of the supply tank (411) is formed to conform to the shape of the elutriation basket (210) or a rotary screen (236) described later.

Here, in order to reduce the overall height of the present invention, the slope inclined downward toward the inside may be slightly larger than the horizontal plane. The feed guide (410) may be connected to a vibration motor (not shown) to assist movement of the food material by vibration, so that guiding and discharging of the food material can be achieved also at a small inclination, and furthermore, the overall height of the present invention can be reduced by lowering the inclination of the feed guide (410), thereby enabling downsizing of the product.

In addition, as shown in fig. 3, a sealing adapter (414) is provided between the panning device (200) and the cooking device (300). The top of the sealing adapter (414) is formed to conform to the shape of the panning barrel (210) or the rotating screen (236) so as to be tightly connected. The bottom of the sealing adapter (414) can be tightly connected with the edge (312) of the inner container (310) to seal. A steam outlet (415) is formed on one side, and steam generated by the rise of the internal pressure of the liner (310) is discharged through the steam outlet (415).

Fig. 5 and 6 are perspective views of a panning apparatus in a full-automatic rice cooker apparatus according to the present invention.

As shown in fig. 5 and 6, the elutriation apparatus (200) is located at a lower side of the grain supply apparatus (100), and elutriation is performed before food materials supplied from the grain supply apparatus (100) are heated in the cooking apparatus (300), and the elutriation apparatus (200) includes: a washing tub (210) for receiving the fed food material through a feed chute (211), and for rotating the food material downward after washing, and for feeding the washed food material to a cooking device (300); a blade (220) which is rotated in the forward and reverse directions in the washing tub (210) and which sweeps away impurities adhering to the food material to wash the food material; and a tub bracket (230) disposed at an outer side of the tub (210) to be raised and lowered to a certain height when storing, washing and cooking.

The washing tub (210) is used for washing food materials, and is used for supplying and discharging the food materials through a feeding groove (211) with one side open, and food materials and washing water are contained in the washing tub.

The both ends of the washing tub (210) are provided with a washing tub center shaft (212), wherein the washing tub center shaft (212) at the rear side is connected with a washing tub driving gear (234) of a multistage motor (232), and a washing tub water inlet (214) for supplying washing water to the inside of the washing tub (210) and a washing tub water outlet (215) for discharging impurities after washing and washing water are formed at the front side of the washing tub (210).

The tub hose (640) includes a water inlet hose (641) connected to the tub water inlet (214) and a water discharge hose (642) connected to the tub water outlet (215), and the tub hose (640) is telescopic, so that even if the tub (210) moves up and down or rotates, the connection state can be maintained without falling off.

A washing tub drain pipe (213) communicating with the washing tub water inlet (214) is formed at the top of the washing tub (210), and washing water is discharged to the inside of the washing tub (210) through a plurality of water dividing holes (213 a) formed on the washing tub drain pipe (213).

The inside of the washing barrel (210) is provided with blades (220) for washing food materials. The blade (220) is composed of a washing blade (221), a scraper blade (222) and a blade rotating shaft (223), a spacing rod is formed on the washing blade (221) and used for sweeping impurities attached to food materials, the scraper blade (222) is plate-shaped and convenient for sweeping the food materials, and the washing blade (221) and the scraper blade (222) are fixed on the blade rotating shaft (223).

The blade rotation shaft (223) is formed to protrude from the front side or the rear side of the washing tub (210), and is provided inside the washing tub center shaft (212). The vane rotary shaft (223) is hollow, and the washing water flows into the hollow, and is discharged to the outside through the water dividing hole (213 a).

The blade rotating shaft (223) and the scraper blade (222) are also provided with water diversion holes (213 a). The washing water flowing in the hollow blade rotation shaft (223) is discharged through the water dividing hole (213 a), and when the washed food is supplied to the cooking device (300), the food remained in the washing tub (210) and on the blade (220) can be washed.

The tub (210) receives food materials supplied from the grain supply device (100) through the feed chute (211), and the tub drain (213) or the water diversion hole (213 a) formed on the vane (220) supplies washing water. After the food and the washing water enter the washing tub (210), the washing blade (221) repeatedly rotates forward and backward to clean the impurities attached to the food.

After the washing is completed, the washing tub (210) is rotated so that the feed chute (211) is directed downward, and the food and washing water are supplied to the cooking device (300). At this time, in order to ensure that food is discharged through the feed chute (211) only at the upper portion of the cooking device (300), the scraper blade (222) is disposed at the inner side of the feed chute (211), and the elutriation tub (210) is rotated not to be perpendicular to the feed chute (211) so as to prevent the food from being poured down. At this time, the washing tub (210) and the blades (220) are vibrated by providing a vibration motor (not shown), so that the food remaining in the washing tub (210) is entirely dropped into the cooking device (300) by the vibration.

As shown in fig. 6, one side of the washing tub (210) is provided with a screen (216) formed at a specific distance from a washing tub drain (215). The cross-sectional area of the screen (216) is greater than the cross-sectional area of the elutriation tub drain (215), so that the flow through the screen at one time is much greater than the flow through a filter of the size of the elutriation tub drain (215).

The screen (216) allows only impurities removed from the food material to drain with the wash water and prevents the food material from leaking out of the wash tub drain (215).

If the strainer is provided on the cross section of the tub drain (215), since the cross section of the tub drain (215) is limited, the filtration of impurities and the flow rate of the washing water become slow, and when many impurities are attached and accumulated on the strainer, the permeable area of the strainer becomes small, resulting in a significant decrease in drainage efficiency, thus extending the time required to complete cooking.

As a result, the time for which the washing water containing impurities after washing in the washing tub (210) stays in the washing tub (210) becomes long, and impurities in the washing water are redeposited on the food materials, so that the number of times of washing needs to be increased, and washing efficiency is lowered.

Thus, the present invention forms the area of the screen (216) to be larger than the sectional area of the washing tub drain (215), thereby increasing the throughput of the screen (216) and speeding up the drain.

In addition, the invention also provides a filter chamber (217), wherein the filter chamber (217) is a space formed by a certain distance between the filter screen (216) and the washing barrel water outlet (215). The filtering chamber (217) is a space through which the washing water passing through the filtering screen (216) passes before flowing into the washing tub drain (215), and only the washing water from which impurities are removed by passing through the filtering screen (216) can flow into the filtering chamber (217). Through a screen (216) having a cross-sectional area greater than the cross-sectional area of the wash bowl drain (215) in greater amounts. After the impurity-removed washing water passes through the filter screen (216), it is rapidly discharged through the washing tub drain outlet (215) without the filter, through the filter chamber (217).

The elutriated water stays in the filtering chamber (217) for a period of time, thereby forming a water depth larger than the diameter of the elutriation tub drain (215), so that the flow rate of the elutriation water flowing through the elutriation tub drain (215) is increased and the drainage rate is also increased.

Therefore, the coexistence time of the washing water containing impurities and the food material is shorter, and redeposition on the food material is reduced to the maximum extent, so that the required washing water amount and washing times are reduced, and the washing efficiency is improved.

Fig. 7 illustrates a multi-stage motor of the full-automatic rice cooker apparatus according to the present invention.

As shown in fig. 7, the central shaft (212) of the elutriation tub and the rotation shaft (223) of the vane are formed coaxially and rotated on the same shaft, and the rotation force is provided by a multi-stage motor (232) located at the rear of the elutriation tub (210). In the multistage motor (232), a blade driving gear (233) is inserted into the hollow interior of a washing tub driving gear (234), and a plurality of motors (M) for rotating both gears are provided.

A washing tub drive shaft (234 a) is formed by extending from the washing tub drive gear (234), and the washing tub drive shaft (234 a) and the washing tub center shaft (212) are connected by a mechanical structure such as a concave-convex structure.

A vane drive shaft (233 a) is formed extending from the vane drive gear (233), the vane drive shaft (233 a) being inserted into the hollow interior of the wash tub drive shaft (234 a). The blade drive shaft (233 a) and the blade rotation shaft (223) are connected by a mechanical structure such as a concave-convex structure.

The washing tub (210) and the blades (220) receive a rotational force provided by the multistage motor (232) through a mechanical structure such as a concave-convex structure. By this connection, the washing tub (210) can be freely moved in the length direction and can receive a transmitted rotational force when engaged.

Therefore, when the washing tub (210) is taken out forward, the washing tub can be easily taken out without complicated disassembly, and can be cleaned with water without any electric device.

The outside of the washing tub (210) is provided with a washing tub bracket (230) which moves up and down. The rear side of the washing barrel bracket (230) is provided with a multi-stage motor (232) for rotating the washing barrel (210) and the blades (220), lifting wings (235) which are inserted into lifting wing insertion holes (512) of the lifting mechanism (500) are formed on two side surfaces, and a base (231) for stable support is arranged inside the lifting wings. In the present invention, the base (231) may be replaced by any object having a supporting function, such as rollers, bearings, etc., and the term base (231) is a generic term including such a configuration.

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

A gap is formed between the elutriation tub (210) and the bottom of the feed guide (410) at an initial height before the elutriation tub carriage (230) is raised and lowered, and a gap is also formed between the elutriation tub (210) and the top of the sealing adapter (414). The height is defined as a first height.

The elutriation tub (210) elutriates food material at a first height of the elutriation tub bracket (230), and a gap exists between a bottom of the feed guide (410) and a top of the sealing adapter (414), so that the elutriation tub (210) can smoothly rotate forward and backward without contact and friction.

Fig. 8 to 10 are sectional views showing the operation state of the panning apparatus during cooking.

As shown in fig. 8, after the food material is completely washed in the washing tub (210), the washing tub (210) is rotated so that the feed chute (211) is positioned at the lower side, and the food material is discharged into the liner (310). The panning barrel (210) is then rotated through an angle, as shown in fig. 9, to tightly connect the sealed outer periphery with the top of the sealing adapter (414). The cooking device (300) heats the inner container (310) to begin cooking, and the tub bracket (230) is lowered by the lifting mechanism (500) so that the tub (210) is tightly connected with the top of the sealing adapter (414), and the gap is eliminated. The height is defined as a second height and the outer periphery of the elutriation basket (210) in close connection with the top of the sealing adapter (414) is defined as a first outer periphery (218).

The washing tub (210) is tightly connected with the top of the sealing adapter (414), so that the top of the sealing adapter (414) is sealed. Therefore, the washing barrel (210) is used as a cover of the inner container (310), and the pressure inside the inner container (310) can be increased during cooking.

The tub (210) serves as a cover of the inner container (310), which has the advantage of simplifying the structure, and simultaneously improving the hygienic condition by cooking the tub (210) by heating it from the bottom at a high temperature, evaporating the residual moisture from the inside, and sterilizing it.

As shown in fig. 10, after cooking is completed, the tub holder (230) is lifted by the lifting mechanism (500) to closely connect the tub (210) with the bottom of the feed guide (410), thereby eliminating a gap between the tub (210) and the bottom of the feed guide (410). The height is defined as a third height, and the outer periphery of the elutriation basket (210) closely connected to the bottom of the feed guide (410) is defined as a second outer periphery (219).

The grain supply apparatus (100) is sealed so that external air cannot enter. The vacuum pump 413 is started, and air in the grain feeding device 100 is sucked through the vacuum suction port 412, so that the vacuum pressure in the grain feeding device is maintained.

Therefore, the risk of deterioration of the food material stored in the grain supply apparatus (100) is reduced, and the breeding of pests such as rice insects in food can be prevented. By maintaining the best quality of the food material, more palatable rice can be cooked.

Furthermore, the first outer periphery (218) of the panning barrel (210) shielding the top of the sealing adapter (414) and the second outer periphery (219) of the panning barrel (210) shielding the bottom of the feed guide (410) consist of different sides. The first peripheral edge (218) for sealing the liner (310) tends to generate a large amount of moisture which, when diffused into the grain delivery device (100), can easily cause deterioration of the food material. Accordingly, by dividing the outer circumferences of the sealing adapter (414) and the feed guide (410) for sealing into a first outer circumference (218) and a second outer circumference (219), respectively, contamination which may occur in the grain feeding apparatus (100) and the cooking apparatus (300) is prevented, thereby improving hygienic conditions.

In another embodiment of the present invention, as shown in fig. 11 and 12, the elutriation basket carrier (230) of the elutriation apparatus (200) may further comprise a rotary screen (236) in close connection with the sealing adapter (414) and the feed guide (410).

The rotary screen (236) is arranged to rotate in the peripheral direction outside the elutriation basket (210). The rotary screen (236) is rotatable and repositionable along the circumferential direction of the elutriation basket (210).

In addition, the rotary screen (236) forms a closed surface (238) and an open surface (237) along the length. A long hole (239 a) through which the center shaft (212) of the washing tub passes is formed on the front side, and a hose through hole (239) through which the washing tub hose (640) passes is formed in a larger area than the long hole (239 a). Even if the rotary screen (236) moves up and down and rotates through the long holes (239 a) and the hose through-holes (239), the elutriation barrel center shaft (212) and the elutriation barrel hose (640) do not interfere with the rotary screen (236).

In other words, the front side of the rotary screen (236) is open, so that when the rotary screen (236) rotates, the elutriation basket central shaft (212) and the hose through opening (239) are not blocked by any structure and thus do not interfere.

The base (231) of the washing tub bracket (230) supports the outer circumference of the rotary screen (236), and the base motor (231 a) rotates the base (231) to rotate the rotary screen (236).

The rotary screen (236) is lifted and lowered together with the tub holder (230) by the lifting mechanism (500). When the panning barrel bracket (230) is at a first height, the rotating screen (236) is not in contact with the sealing adapter (414) and the feed guide (410).

When the pan carrier (230) is lowered to the second height by the lifting mechanism (500), the sealing surface (238) of the rotary screen (236) is tightly connected to the top of the sealing adapter (414), and the liner (310) is sealed, so that the pressure rises during cooking.

When the wash tub carriage (230) is raised to a third height by the lifting mechanism (500), the closing surface (238) of the rotary screen (236) is in close connection with the bottom of the feed guide (410), and the cereal feeding device (100) is sealed. At this time, when the rotary screen (236) moves up and down, the elutriation basket (210) does not move following the elutriation basket bracket (230), but is fixed at the first height.

Next, with reference to fig. 13, a workflow of the panning apparatus (200) in the embodiment provided with the rotary screen (236) will be described.

As shown in fig. 13 (a), the initial state is a position where the feed chute (211) is upward so as to receive the fed food material from the grain feeding apparatus (100), and thus, the open face (237) of the rotary screen (236) is also upward, and the tub tray (230) is not raised or lowered, but is located at the initial position, i.e., the first height. In this position, the rotary screen (236) forms a gap between the top of the sealing adapter (414) and the bottom of the feed guide (410), respectively. Furthermore, since a gap is formed between the inner surface of the rotary screen (236) and the elutriation drum (210), the rotation of the elutriation drum (210) is not disturbed.

In this position, the food material is fed from the grain feeding apparatus (100) to the panning barrel (210), and panning is completed inside thereof.

After the washing is completed, the washing drum (210) is rotated so that the feed chute (211) and the open surface (237) of the rotary screen (236) face downward. Fig. 13 (b) shows the feed chute (211) in the horizontal direction when rotated downward. Fig. 13 (b) shows a view when the open face (237) is positioned in the horizontal direction during the rotation of the rotary screen (236) as well, but when the feed chute (211) of the elutriation basket (210) is positioned in the horizontal direction during the rotation, the rotary screen (236) may not rotate but the open face (237) is positioned in the vertical direction. When the tub (210) rotates, since the tub hose (640) connected to the front side of the tub is telescopic, the connected state is maintained by the telescopic while the tub (210) rotates. The wash tub hose (640) moves along the line of the hose through opening (239).

As shown in fig. 13 (c), the feed chute (211) and the open face (237) are positioned below, so that the elutriated food material inside the feed chute is poured out and discharged into the liner (310).

After the discharge, as shown in fig. 13 (b), the washing tub (210) is rotated so that the feed chute (211) is positioned in the horizontal direction and the open surface (237) of the rotary screen (236) is also positioned in the horizontal position. At this point, the closing surface (238) faces downward.

As shown in fig. 13 (d), the lifting mechanism (500) lowers the panning barrel bracket (230) to a second height. The rotary screen (236) is also lowered together to tightly connect the closure surface (238) to the top of the sealing adapter (414) so that the liner (310) is sealed. The outer periphery of the rotary screen (236) tightly connected to the top of the sealing adapter (414) is defined as a third outer periphery (238 a). After the sealed liner (310) is heated, its internal pressure increases. At this time, the elutriation tub (210) is fixed at the first height so as not to rise or fall, and the top of the elutriation tub (210) may be in contact with the inner surface of the rotary screen (236).

After cooking is completed, the tub tray (230) is raised again to the first height as shown in fig. 13 (b). In addition to the panning and cooking process, as shown in fig. 13 (e), the lifting mechanism (500) lifts the panning barrel bracket (230) to a third height to secure the food stuff stored in the storage barrel (110). At this time, the feed chute (211) and the open face (237) of the rotary screen (236) are positioned horizontally, and the closed face (238) of the rotary screen (236) faces upward. The elutriation tub (210) is fixed at a first height that is neither raised nor lowered, and a bottom of the elutriation tub (210) may be in contact with an inner surface of the rotary screen (236).

The bottom of the feed guide (410) is tightly coupled to the sealing surface (238) of the rotary screen (236) to seal the storage tub (110) from the outside air. At this time, the closing surface (238) of the rotary screen (236) tightly connected to the bottom of the feed guide (410) is defined as a fourth outer peripheral edge (238 b).

Then, a vacuum pump (413) is started, and air in the grain supply device (100) is sucked through a vacuum suction port (412), so that the inside of the grain supply device is kept in a vacuum pressure state. Can prevent the breeding of insect pests such as rice worm and the like and reduce the deterioration of grains to the maximum extent under the condition of keeping the vacuum pressure inside.

When the tub holder (230) is positioned at the first height, a gap is formed between the tub (210) and the rotary screen (236), helping the tub (210) to smoothly rotate, and an open face (237) of the rotary screen (236) is positioned at an upper side or a lower side to achieve feeding and discharging of food materials.

When the elutriation basket carrier (230) is at the second elevation, the sealing surface (238) of the rotary screen (236) is in close contact with the top of the sealing adapter (414), and the top of the elutriation basket (210) may be in contact with the inner surface of the rotary screen (236). The inner container (310) is sealed so that the pressure rises during heating cooking.
