Description

Technical Field

[0001] The present invention relates to an automatic rice cooker and a rice washing component having a rice washing function. Background Art

[0002] In the case of conventional rice cookers, the user directly pours rice and water in the desired amounts into the inner pot to cook rice, and delicious rice can only be cooked when the ratio of rice to water is constant. In recent years, for users who are not good at adjusting the ratio of rice to water, automatic rice cookers that automatically pour a fixed amount of rice and water according to a specified capacity have emerged on the market.

[0003] However, when transferring unwashed rice, there are problems such as contamination due to sticking of rice powder or foreign substances to the transfer pipeline and the rice pouring part, or steam leakage due to poor sealing through the adhered foreign substances. When washing rice with water, it is necessary to drain the washing water, so there is a disadvantage that the installation position of the automatic rice cooker is limited. To solve this problem, a waterless rice washing device that only removes fine rice powder on the surface of white rice by friction through stirring has been proposed. However, it is limited to remove fine rice powder on the surface of white rice only by friction by stirring.

[0068] Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

[0069] Figure 1 The sectional view showing the rice pouring path of the automatic rice cooker with rice washing function according to an embodiment of the present invention, Figure 2Partial exploded view of an automatic rice cooker with a rice washing function according to an embodiment of the present invention.

[0070] The rice washing function provided by the automatic rice cooker with a rice washing function of the present invention is 'dry rice washing', which means that the rice is physically rubbed without water to remove the rice flour existing on the surface of the rice. During the rice pounding step, fine concavo-convex portions are generated on the surface of the rice, and rice flour adheres between the concavo-convex portions. By physically rubbing the rice, the rice flour adhering to the surface of the rice is removed, thereby preventing malfunction caused by the accumulation or adhesion of rice flour in the rice pouring path of the automatic rice cooker. In one embodiment of the present invention, the rice pouring path is only one embodiment of the rice pouring path, and other types of grains other than rice can also be transferred.

[0071] In an automatic rice cooker with a rice washing function according to an embodiment of the present invention, a main body 10 is combined with a base 1, and a lid 20 for opening and closing the main body 10 is provided on the main body 10. In addition, an inner pot lid 30 for sealing the upper part of the inner pot 12 is combined with the lid 20.

[0072] In addition, the automatic rice cooker with a rice washing function includes a rice bucket 61 for automatically pouring rice into the main body 10 and a water bucket 71 for automatically pouring water into the main body 10. Here, the base 1 has a rice bucket coupling portion 60 for coupling the rice bucket 61 on one side of the main body 10 and a water bucket coupling portion 70 for coupling the water bucket 71 and controlling the pouring of water. A water transfer pipe 92 (refer to Figure 3 ) and a rice transfer pipe 94 are connected between the water bucket coupling portion 70 and the rice bucket coupling portion 60.

[0073] A metering portion 600 for metering and discharging the rice is installed at the lower part of the rice bucket 61, and a motor 62 for driving the metering portion 600 is provided at the rice bucket coupling portion 60. The discharge of the rice through the metering portion 600 is controlled by controlling the rotation of the motor 62. When the metering portion 600 rotates at a specified angle by the motor 62, the rice in the metering chamber of the metering portion 600 falls into the inside of the stirring assembly 800.

[0074] The rice that falls from the inside of the stirring assembly 800 into the rice suction portion 64 due to the suction pressure of the suction fan 80 moves along the rice transfer pipe 94 to the cyclone rice separator 100 described later. At this time, a plurality of holes 65 (refer to Figure 5 ) are formed in the rice suction portion 64, and the holes allow air to flow in to make the air flow due to the suction pressure of the suction fan 80. In addition, a rice transfer pipe 94 connected in the tangential direction of the cyclone rice separator 100 and connected to the rice bucket coupling portion 60, an air suction pipe 96 connected to one side of the cyclone rice separator 100 and connected to the suction fan 80 to generate suction pressure, a valve 200 for opening and closing the opening and closing hole 102 penetrating the axial direction of the cyclone rice separator 100, and a valve opening and closing device (not shown) for pressing the upper end of the valve 200 to open and close are provided.

[0075] An inner pot 12 is provided on the main body 10, into which rice and water are poured to substantially cook the rice and keep the cooked rice at an appropriate temperature. A heating unit (not shown), such as a hot plate heater or an induction heating device, is provided around the inner pot 12.

[0076] Figure 3 It is a top view of an automatic rice cooker with a rice washing function according to an embodiment of the present invention. Figure 4 It is along Figure 3 a cross-sectional view taken along D - E of Figure 5 and Figure 6 It is along Figure 3 a cutaway perspective view taken along B - E of

[0077] In the metering unit 600, the rice stored in the rice bucket 61 is metered and a specified amount is discharged to a stirring assembly 800 (refer to Figure 1 ).

[0078] The rice washing assembly of the present invention is formed between the rice bucket 61 on the base 1 and the rice suction unit 64, and performs waterless rice washing on the rice provided from the rice bucket 61 through the rice bucket coupling part 60 and discharges it to the rice suction unit 64, and generally includes a stirring assembly 800 (refer to Figure 1 ) and an air circulation assembly 900.

[0079] The stirring assembly 800 (refer to Figure 1 ) includes: a rice washing chamber 802, which is composed of a stirring outer cylinder 810 installed on the base 1, a stirring inner cylinder 820 installed inside the stirring outer cylinder 810, and a stirring guide 830 installed on the upper surface of the stirring outer cylinder 810; and stirring blades 840, which rotate in the rice washing chamber 802 to physically rub the rice.

[0080] On the other hand, the rice bucket coupling part 60 of the base 1 further includes a stirring cover 850 provided between the metering unit 600 and the stirring guide 830. The stirring cover 850 includes a funnel part 852 that guides the rice discharged through the metering unit 600 to the rice washing chamber 802, and a motor 62 for driving the metering unit 600 is provided on the stirring cover 850.

[0081] When a cooking command is input, after opening the valve 200 of the opening / closing hole 102 of the opening / closing cyclone rice separator 100, the suction fan 80 is operated. The suction pressure of the suction fan 80 acts on the rice suction part 64 through the air suction pipe 96, the cyclone rice separator 100, and the rice transfer pipe 94. When the microcomputer (not shown) drives the rice bucket coupling part 60, more specifically, drives the motor 62 provided on the stirring lid 850 to operate the metering part 600 provided at the lower part of the rice bucket 61, an appropriate amount of rice is poured into the rice washing assembly through the metering part 600, and after being washed without water in the rice washing assembly, it is discharged to the rice suction part 64. The discharged rice is poured into the interior of the inner pot 12 along the rice transfer pipe 94 by the suction pressure generated by the suction fan 80. At this time, a plurality of holes 65 for air inflow are formed in the rice suction part 64 so that air flows through the suction pressure of the suction fan 80.

[0082] Figure 7 is an exploded view of the rice bucket and the metering part of an automatic rice cooker with a rice washing function according to an embodiment of the present invention, Figure 8 is a view showing the metering part of an automatic rice cooker with a rice washing function according to an embodiment of the present invention.

[0083] The metering part 600 of an automatic rice cooker with a rice washing function according to an embodiment of the present invention includes a metering part lid 620 that is coupled to the lower side of the rice bucket 61 for storing grains such as rice to form the bottom surface of the rice bucket 61, a main meter 630, an auxiliary meter 640, and a metering part housing 650. Holes 621 and 622 for discharging the rice stored in the rice bucket 61 are formed in the metering part lid 620. When the rice stored in the rice bucket 61 is discharged through the holes 621 and 622, a certain amount is metered and discharged to the lower part through the main meter 630 and the auxiliary meter 640. The rice bucket 61 is divided into two or more storage compartments by a detachable partition (not shown), and the meters 630 and 640 are located below the divided storage compartments. The main meter 630 and the auxiliary meter 640 are rotatably provided in the metering part housing 650, and the metering part housing 650 has discharge ports 651 and 652 for discharging rice at positions that do not overlap with the holes 621 and 622 of the metering part lid 620.

[0084] The metering part housing 650 is coupled to the stirring lid 850 of the rice bucket coupling part 60 (refer to Figure 4 ). A motor 62 for providing a rotational force to the meters 630 and 640 is provided on the stirring lid 850 (refer to Figure 4 ).

[0085] On the measuring unit cover 620, there are holes 621 and 622 for discharging rice from the rice bucket 61. Preferably, one hole 621 and 622 is formed at the corresponding position of each storage compartment respectively, and there are two holes in one embodiment of the present invention. There are cleaners 623 and 624 provided on at least one side of the holes 621 and 622 and protruding downward to sweep the rice discharged into the meters 630 and 640 into the measuring chamber. The cleaners 623 and 624 substantially only use the cleaners located in front of the rotation direction of the meters 630 and 640. Therefore, there is only one cleaner 624 installed on the auxiliary storage compartment 614 side of the auxiliary meter 640 that rotates only in one direction, which is provided only in the forward rotation traveling direction. The main meter 630 provided in the main storage compartment 612 rotates in the forward direction and the reverse direction. Therefore, the cleaners 623 are attached to both sides of the hole 621 respectively.

[0086] The cleaners 623 and 624 are bent into an L shape, bent downward through the hole 621 and extended. And the cleaners 623 and 624 horizontally sweep the upper surface of the rice poured into the meters 630 and 640 to make the upper surface flat. Thus, not only can the amount of rice in the meters 630 and 640 be kept constant, but also it can prevent the rice from being caught between the meters 630 and 640 and the measuring unit cover 620 of the rice bucket 61 to prevent the rotation of the meters 630 and 640. At this time, the cleaners 623 and 624 are preferably made of a soft and elastic material such as rubber or silicon.

[0087] On the other hand, the measuring unit cover 620 has rotor shaft holes 625 and 626, and blade-type rotors 627 and 628 are connected to the central axes of the respective meters 630 and 640. The blade-type rotors 627 and 628 rotate together with the meters 630 and 640 while agitating the rice in the rice bucket 61 so that the rice can be discharged well through the holes 621 and 622. In addition, the rice stored in the rice bucket 61 is agitated to flatten the upper surface, thereby improving the accuracy when sensing the remaining amount of rice.

[0088] The measuring unit housing 650 has a bottom surface 650a and a side wall 650b. As described above, the bottom surface 650a is formed with a main discharge port 651 for discharging the rice flowing into the main meter 630 to the lower part and an auxiliary discharge port 652 for discharging the rice flowing into the auxiliary meter 640 to the lower part.

[0089] In addition, at the installation position of the main meter 630, there is a gear hole 653 for the driving gear 62b connected to the motor 62 to penetrate and connect to the main meter 630. And at the installation position of the auxiliary meter 640, there is a coupling shaft 654 for coupling with the reverse rotation prevention parts 654a, 654b, 654c (refer to Figure 11 ) to be described later.

[0090] Figure 9FIG. is a view showing a main measuring device of an automatic rice cooker having a rice washing function according to an embodiment of the present invention.

[0091] Referring to Figures 7 to 9 , the main measuring device 630 is disposed within a measuring unit housing 650. A lower groove 631b engaged with a gear portion 854 of the motor 62 is formed at a lower portion of a central axis 631 of the main measuring device 630, and an upper groove 631a engaged with a rotor shaft 627a of a blade-shaped rotor 627 is formed at an upper portion of the central axis 631. The gear portion 854 and the lower groove 631b are engaged to transmit the rotational force of the motor 62 to the main measuring device 630, and the rotor shaft (627a; referring to Figure 11 ) engaged with the upper groove 631a rotates, and the blade-shaped rotor 627 rotates to agitate the rice.

[0092] The main measuring device 630 further includes: an outer wheel 632, which is a cylindrical shape concentric with the central axis 631 and has gear teeth 632a formed on an outer circumferential surface; and a plurality of partitions 633, which radially connect the outer wheel 632 and the central axis 631 like spokes and divide them into a plurality of measuring chambers 630a. The measuring chambers 630a of the main measuring device 630 are disposed at positions overlapping with holes 621 of a measuring unit cover 620 and a main discharge port 651 of the measuring unit housing 650.

[0093] In addition, one or more magnets 635 are provided to detect the rotation amount and rotation of the main measuring device 630. The magnets 635 are disposed on an inner circumferential surface of the outer wheel 632 and may have different numbers according to requirements. The main measuring device 630 includes a magnet receiving portion 634 into which the magnets 635 are inserted, and after the magnets 635 are inserted into the magnet receiving portion 634, they are fixed by being blocked by a plug 636 made of an elastic rubber material.

[0094] Figure 10 FIG. is a view showing an auxiliary measuring device of an automatic rice cooker having a rice washing function according to an embodiment of the present invention.

[0095] The auxiliary measuring device 640 has a form in which an outer portion 640b is coupled to an outer circumferential surface of an inner portion 640a. A ratchet protrusion 645a is formed at a lower end of the outer circumferential surface of the inner portion 640a, and a ratchet gear 642b is formed at a lower end of the outer portion 640b, thereby allowing the outer portion 640b to rotate with respect to the inner portion 640a only in one direction.

[0096] The inner portion 640a includes: a central axis 642a, which forms a center of rotation; an outer wheel 644a, which is formed in a cylindrical shape and is concentric with the central axis 642a and has a ratchet protrusion 645a formed at a lower end of an outer circumferential surface; and a plurality of partitions 646a, which connect the outer wheel 644a and the central axis 642a radially like spokes and divide them into a plurality of measuring chambers 641a.

[0097] The outer 640b is cylindrical and is joined to the outer peripheral surface of the inner 640b. A ratchet gear 642b is formed at the lower end, and a tooth shape 644b that meshes with the gear tooth shape 632a of the main meter 630 is formed on the outer peripheral surface. Thus, when the outer 640b rotates counterclockwise, the ratchet projection 645a and the ratchet gear 642b engage with each other, and the inner 640a rotates together with the outer 640b. Conversely, when the outer 640b rotates clockwise, the ratchet gear 642b of the outer 640b rises along the ratchet projection 645a of the inner 640a, allowing relative rotation. Thus, the outer 640b rotates relative to the inner 640a and idles.

[0098] The metering chamber 641a of the auxiliary meter 640 needs to be provided at a position overlapping with the hole 622 of the metering unit cover 620 and the auxiliary discharge port 652 of the metering unit housing 650.

[0099] Figure 11 It is a diagram showing an enlarged view of the reverse rotation prevention unit of the metering unit and the auxiliary meter of the automatic rice cooker having a rice washing function according to an embodiment of the present invention.

[0100] The reverse rotation prevention units 654a, 654b, 654c include: an elastic member 654a that is inserted into the coupling shaft 654 and whose lower end is supported by the metering unit housing 650; a ratchet unit 654b that is supported by the upper end of the elastic member 654a so as to be movable up and down, and has a coupling hole joined to the coupling shaft 654; and a stopper 654c that prevents the ratchet unit 654b from detaching from its upper part and restricts the upper position of the ratchet unit 654b, and is fixed to the coupling shaft 654. At this time, as described above, the coupling shaft 654 has an angular shape such as a hexagonal column to prevent the ratchet unit 654b from rotating relative to the coupling shaft 654, and the coupling hole has a shape corresponding to the coupling shaft 654. In an embodiment of the present invention, as long as the coupling shaft 654 and the coupling hole are in a form that can prevent rotation, they may also be in the shape of a hexagonal column and a hexagonal hole, or a quadrangular column or a quadrangular hole, or a cylindrical shape having a key hole or the like.

[0101] The ratchet unit 654b does not rotate relative to the coupling shaft 654 and only moves up and down. It is forced to move upward by the elastic member 654a, but the highest point is restricted by the stopper 654c.

[0102] Figure 12 It is a diagram showing the lower surface of the rotation shaft of the auxiliary meter of the automatic rice cooker having a rice washing function according to an embodiment of the present invention. Figure 13 It is a diagram showing the state in which the reverse rotation prevention unit of the auxiliary meter of the metering unit housing of the automatic rice cooker having a rice washing function according to an embodiment of the present invention prevents reverse rotation inside the auxiliary meter. Figure 14This is a diagram showing the appearance of the reverse prevention part of the auxiliary meter of the meter housing of an automatic rice cooker with a rice washing function according to an embodiment of the invention, allowing forward rotation inside the auxiliary meter.

[0103] A ratchet gear 643a is formed on the central axis 642a of the inside 640a of the auxiliary meter on the lower surface, and the ratchet part 654b of the reverse prevention part is pressed by an elastic member 654a and abuts. Thus, the clockwise rotation of the inside 640a is restricted. Conversely, when rotating counterclockwise, while rotation is allowed along the inclined surfaces of the ratchet part 654b supported by the elastic member 654a and the ratchet gear 643a of the central axis 642a, the ratchet part 654b is supported by the elastic member 654a and repeatedly moves up and down.

[0104] When the outside 640b rotates clockwise, relative rotation is allowed. The outside 640b needs to rotate relative to the inside 640a and idle, but due to the frictional force between the inside 640a and the outside 640b, the inside 640a rotates along the outside 640b, and through the reverse prevention part, the clockwise rotation of the inside 640a, that is, reverse rotation, can be prevented.

[0105] Figure 15 This is a diagram showing the rotation of the meter when the motor rotates forward at the rice bucket coupling part of an automatic rice cooker with a rice washing function according to an embodiment of the present invention.

[0106] Hereinafter, the forward rotation of the motor 62 represents clockwise rotation, and the reverse rotation of the motor 62 represents counterclockwise rotation. Therefore, the clockwise direction of the main meter 630 rotating in the same direction as the motor 62 is the positive direction. Since it rotates by meshing with the main meter 630, in the case of the auxiliary meter 640 rotating in the opposite direction to the main meter 630, the counterclockwise rotation becomes the reference for the positive direction.

[0107] When the motor 62 rotates in the positive direction, the gear tooth profile 632a of the main meter 630 and the tooth profile 644b of the auxiliary meter 640 mesh with each other and rotate. In the case of the auxiliary meter 640, as described above, the outside 640b cannot rotate counterclockwise relative to the inside 640a, so the outside 640b and the inside 640a need to rotate together. The reverse prevention part allows the counterclockwise rotation of the inside 640a, so the auxiliary meter 640 can rotate when the motor 62 rotates forward.

[0108] Therefore, rice is discharged through the main discharge port 651 and the auxiliary discharge port 652 of the meter housing 650.

[0109] Figure 16It is a diagram showing the rotation of a meter when a motor of a rice bucket coupling part of an automatic rice cooker with a rice washing function according to an embodiment of the present invention reverses.

[0110] When the motor 62 rotates in the reverse direction, the gear tooth shape 632a of the main meter 630 and the tooth shape 644b of the auxiliary meter 640 mesh with each other, so that the outside 640b of the auxiliary meter 640 rotates in the clockwise direction. The outside 640b is allowed to rotate clockwise relative to the inside 640a, and the reverse rotation prevention part restricts the clockwise rotation of the inside 640a. Therefore, when the motor 62 reverses, only the outside 640b rotates while the inside 640a stops. Accordingly, the measuring chamber 641a formed in the inside 640a and the blade-type rotor 628 connected to the central shaft 642a of the inside 640a do not rotate either.

[0111] Therefore, rice is not discharged through the auxiliary discharge port 652 of the measuring part housing 650.

[0112] Figure 17 It is a cross-sectional view of a stirring lid of an automatic rice cooker with a rice washing function according to an embodiment of the present invention. Figure 18 It is a perspective view of a stirring lid of an automatic rice cooker with a rice washing function according to an embodiment of the present invention.

[0113] As described above, the stirring lid 850 is provided on the base 1 to form the upper surface of the rice bucket coupling part 60, and is provided between the measuring part 600 and the rice washing assembly. It has a funnel part 852 for guiding the rice discharged through the measuring part 600 to the rice washing assembly.

[0114] When cooking rice for multiple people, even when cooking rice for multiple people, the measuring part 600 can repeatedly measure and discharge one person's portion at a time to the rice washing assembly, and the rice washing assembly can wash the discharged one person's portion of rice and pour the washed one person's portion of rice into the main body 10. As a result, the rice washing assembly can be miniaturized, and further, the size of the automatic rice cooker with a rice washing function can be miniaturized.

[0115] At a distance from the funnel part 852, a motor 62 for driving the measuring part 600 is provided on one side, and a gear part 854 is provided which is coupled to the shaft of the motor 62 to transmit the power of the motor 62 to the main meter 630 (refer to Figure 8 ). On the other hand, the outer peripheral part 856 of the stirring lid 850 is the installation surface provided on the base 1.

[0116] At this time, a hook part 858 is provided on the stirring lid 850 to fix the stirring lid 850 to the rice bucket coupling part 60. Preferably, a coupling groove (not shown) is provided at a position corresponding to the hook part 858 on the rice bucket coupling part 60.

[0117] Figure 19 It is a view of a stirring guide of an automatic rice cooker with a rice washing function showing an embodiment of the invention.

[0118] As described above, the stirring guide 830 is combined with the upper surface of the stirring outer cylinder 810 (refer to Figure 2 ) to form a rice washing chamber 802 (refer to Figure 4 ). The stirring guide 830 has an upper surface 832 that defines the upper surface of the rice washing chamber 802 (refer to Figure 4 ) and a rice pouring hole 834 that is combined with the funnel portion 852 of the stirring lid 850 (refer to Figure 17 ) to pour rice into the rice washing chamber. In addition, in order to connect with the air circulation assembly 900 (refer to Figure 5 ) described later, the stirring guide 830 has an air circulation discharge port 836 that discharges air from the rice washing chamber 802 (refer to Figure 4 ) to the air circulation assembly 900 (refer to Figure 5 ) and an air circulation suction port 838 that sucks air from the air circulation assembly 900 (refer to Figure 5 ) into the rice washing chamber 802 (refer to Figure 4 ). The air circulation discharge hose 910 and the air circulation suction hose 920 are respectively combined with the air circulation discharge port 836 and the air circulation suction port 838.

[0119] Figure 20 It is a perspective view showing the appearance of the stirring outer cylinder of an automatic rice cooker with a rice washing function according to an embodiment of the present invention, Figure 21 It is a perspective view showing the inside of the stirring outer cylinder of an automatic rice cooker with a rice washing function according to an embodiment of the present invention, Figure 22 It is a view showing the state of the stirring outer cylinder being provided at the rice bucket coupling part of an automatic rice cooker with a rice washing function according to an embodiment of the present invention.

[0120] The stirring outer cylinder 810 is provided in the rice bucket coupling part 60 of the base 1 and generally has a cylindrical shape, but does not have a perfect cylindrical shape due to bending or protrusions, etc. The stirring outer cylinder 810 has a rice discharge port 815 for discharging the washed rice, and a step with a higher bottom surface height is formed in the rice discharge port peripheral area 812 where the rice discharge port 815 is formed compared to other areas 811.

[0121] In addition, a stirring blade (840; Figure 5) The stirring motor 842 is fixed by the motor cover 843. For this purpose, a motor setting space 818 that protrudes upward (i.e., is recessed on the lower surface) is provided on the bottom surface of the stirring outer cylinder 810 to prepare a setting space for the stirring motor 842. A through hole 818a through which the shaft of the stirring motor 842 passes is formed in the center of the motor setting space 818. In addition, a rod 860 for opening and closing the rice discharge port 815 is provided in the area 812 around the rice discharge port. The stirring outer cylinder 810 has a rod support portion 819 on its outer surface for setting the rod 860.

[0122] In addition, the stirring outer cylinder 810 has a foreign matter discharge port 814 for discharging the rice powder and foreign matter removed from the rice by the physical friction of the stirring blades 840 ( Figure 5 ) to the outside of the rice washing chamber 802 ( Figure 4 ). The rice powder and foreign matter accumulated in the stirring outer cylinder 810 flow into the discharge flow of the suction fan 80 ( Figure 1 ) and are discharged to the outside of the rice washing chamber 802 ( Figure 4 ). For this purpose, the stirring outer cylinder 81 has a discharge flow inlet 813 for flowing into the discharge flow of the suction fan 80 ( Figure 1 ). The discharge of foreign matter through the discharge flow of the suction fan 80 will be described later. Preferably, the discharge flow flowing in through the discharge flow inlet 813 and the discharge flow discharged through the foreign matter discharge port 814 extend along the tangential direction of the stirring outer cylinder 810 and are formed parallel to each other. In addition, if necessary, the stirring outer cylinder 810 has a terminal portion 816 for connecting the power supply of the motor 62 ( Figure 17 ) installed on the stirring cover 850 ( Figure 17 ), but it is not an essential component. The terminal portion for connecting the power supply of the motor 62 may also be formed at the rice bucket coupling portion 60 or the like.

[0123] Figure 23 is a perspective view of the stirring inner cylinder of an automatic rice cooker with a rice washing function showing an embodiment of the present invention, Figure 24 is a top view of the stirring inner cylinder of an automatic rice cooker with a rice washing function showing an embodiment of the present invention, Figure 25 is an exploded perspective view of the stirring outer cylinder and the stirring inner cylinder of an automatic rice cooker with a rice washing function showing an embodiment of the present invention, Figure 26 is a view showing the state where the stirring outer cylinder, the stirring inner cylinder, and the stirring motor are provided at the rice bucket coupling portion of an automatic rice cooker with a rice washing function showing an embodiment of the present invention.

[0124] The stirring inner cylinder 820 is disposed within the stirring outer cylinder 810 and has a lower surface and a side wall in a cylindrical shape as a whole. The lower surface is composed of an inclined surface 821 that is inclined in a manner of gradually protruding upward as it approaches the center and an outer peripheral portion 822 that is flat on the outer periphery of the inclined surface 821. A motor shaft through-hole 823 is formed at the center of the lower surface for the rotation shaft of the stirring motor 842 to pass through and be connected to the stirring blade 840.

[0125] The stirring inner cylinder 820 is formed with a rice discharging port 825 at a position corresponding to the rice discharging port 815 of the stirring outer cylinder 810, and the two rice discharging ports 815 and 825 are aligned when the stirring inner cylinder 820 is installed within the stirring outer cylinder 810.

[0126] When the stirring inner cylinder 820 is installed in the stirring outer cylinder 810, the stirring inner cylinder 820 is in close contact with the stirring outer cylinder 810 only in the rice discharging port peripheral area 827 where the rice discharging port 825 is formed, and is offset from the stirring outer cylinder 810 in the remaining area 824.

[0127] On the other hand, a plurality of discharge holes 826 are formed in the stirring inner cylinder 820 to discharge the rice powder and foreign matters removed from the rice by the physical friction of the stirring blade 840 to the stirring outer cylinder 810. At this time, the discharge holes 826 are not formed in the rice discharging port peripheral area 827 where the stirring outer cylinder 810 and the stirring inner cylinder 820 are in close contact. In addition, it is preferable that the discharge holes 826 are formed only in the outer peripheral portion 822 of the lower surface to easily discharge the rice powder and foreign matters and prevent foreign matters from flowing into the stirring motor 842.

[0128] On the other hand, an extension portion 828 that is combined with the upper side of the foreign matter discharge port 814 of the stirring outer cylinder 810 is formed on the upper side outer periphery of the side wall of the stirring inner cylinder 820.

[0129] The rice bucket joint portion 60 is first provided on the stirring outer cylinder 810 and then the stirring inner cylinder 820 is combined. At this time, the motor shaft 842a of the stirring motor 842 protrudes into the stirring inner cylinder 820. After a washer 844 and the stirring blade 840 are sequentially inserted into the motor shaft 842a, the stirring blade 840 is set by tightening with a simple nut 846. At this time, the material of the stirring blade 840 is composed of a metal material that can be cleaned and has excellent wear resistance, or an engineering plastic that is harmless to the human body and has excellent wear resistance, etc. In addition, the washer 844 and the simple nut 846 are also preferably made of metal with excellent durability and can be cleaned. The lower surface of the stirring blade 840 preferably has a shape corresponding to the inclined surface 821 of the stirring inner cylinder 820, and the foreign matters and rice powder removed from the rice slide along the inclined surface 821 and are discharged from the discharge holes 826.

[0130] The present invention physically performs waterless rice washing through the stirring assembly 800 ( Figure 4 ) within the rice washing chamber 802 ( Figure 1 ), and through the air circulation assembly 900 ( Figure 5)while performing the waterless rice washing using the air rinsing function together.

Figure 34 FIG. 18 is a view showing the appearance of the air circulation assembly provided at the rice bucket coupling part of the automatic rice cooker with a rice washing function according to an embodiment of the present invention. Figure 35 FIG. 20 is a cross-sectional view of the air circulation assembly provided at the rice bucket coupling part of the automatic rice cooker with a rice washing function according to an embodiment of the present invention.

[0132] According to the first embodiment, in order to perform the operation in the rice washing chamber 802 formed by the stirring outer cylinder 810 ( Figure 26 ), the stirring inner cylinder 820 ( Figure 26 ), and the stirring guide 830 Figure 4) An air rinsing function for removing rice flour and foreign substances from the surface of rice by circulating air. As described above, the stirring guide member 830 is provided with an air circulation discharge port 836 and an air circulation suction port 838, and an air circulation discharge hose 910 and an air circulation suction hose 920 are respectively connected to the air circulation discharge port 836 and the air circulation suction port 838. At this time, both ends of the air circulation discharge hose 910 and the air circulation suction hose 920 can be separated from the stirring guide member 830, the air circulation discharge port 826, and the air circulation suction port 838. Thus, the air circulation discharge hose 910 and the air circulation suction hose 920 are disassembled to remove or clean the accumulated rice flour and foreign substances. At this time, the air circulation discharge hose 910 and the air circulation suction hose 920 are formed in different shapes from each other, so that misassembly can be prevented. In addition, an air circulation discharge path 930 connected to the air circulation discharge hose 910 is formed in the rice bucket coupling part 60, and the air circulation discharge path 930 is covered by the stirring lid 850 ( Figure 2 ) to form a passage for circulating air between the rice bucket coupling part 60 and the stirring lid 850.

[0133] Different from the first embodiment, in order to connect the air circulation assembly and the stirring guide member 830, a pipe and a wind deflector can be provided instead of the hose. According to the second embodiment, in order to circulate air in the rice washing chamber 802 ( Figure 4 ) composed of the stirring outer cylinder 810, the stirring inner cylinder 820, and the stirring guide member 830 to perform the air rinsing function. As described above, the stirring guide member 830 is provided with an air circulation discharge port 836 and an air circulation suction port 838, and an air circulation discharge pipe 910a and an air circulation suction pipe 920a are respectively connected to the air circulation discharge port 836 and the air circulation suction port 838. In addition, an air circulation discharge path 930 connected to the air circulation discharge hose 910 is formed in the rice bucket coupling part 60, and the air circulation discharge path 930 is covered by the stirring lid 850 to form a passage for circulating air between the rice bucket coupling part 60 and the stirring lid 850. At this time, in a state where the rear end of the stirring lid 80 is supported by the rice bucket coupling part 60, the front part is covered and pressed, and the hook part 858 is coupled to the rice bucket coupling part 60 to perform one-key coupling.

[0134] In order to connect the air circulation discharge path 930 formed in the rice bucket coupling part 60 and the air circulation discharge pipe 910a, an air circulation discharge connector 914a is provided at the outlet side end of the air circulation discharge path 930. In addition, an air circulation suction connector 924a for coupling the air circulation suction pipe 920a is provided in the rice bucket coupling part 60. The air circulation suction connector 924a is connected to a cyclone suction hose 926 ( Figure 1 ) described later.

[0135] On the other hand, windshields 836a, 838a, 912a, 922a are provided at the air circulation outlet 836 and air circulation inlet 838 formed in the stirring guide 830, and the air circulation outlet connector 914a and air circulation inlet connector 924a provided at the rice bucket joint 60, respectively, to prevent air leakage. When both ends of the air circulation outlet hose 910 and the air circulation inlet hose 920 are connected to the air circulation outlet 836, the air circulation inlet 838, the air circulation outlet connector 914a, and the air circulation inlet connector 924a, the windshields 836a, 838a, 912a, 922a are pressed to achieve airtight sealing.

[0136] On the other hand, in order to block the flow of rice into the air circulation assembly, it is preferred to set rice filters 836b, 838b ( Figure 5 , Figure 28 ). Rice filter 836b, 838b ( Figure 5 , Figure 28 ) is formed into a mesh shape, and when the stirring guide 830 is injection molded, it is combined with the stirring guide 830 by an insert molding method embedded in the mold. Of course, it can also be made into another component and attached to the stirring guide 830.

[0137] Air circulation assembly 900( Figure 5 ) is provided with a cyclone portion 940 formed on the stirring guide 830 ( Figure 19 ) of the air circulation outlet 836 ( Figure 19 and Figure 27 ) and air circulation inlet 838 ( Figure 19 and Figure 27 ) and separated from the circulating air included in the rice washing chamber 802 ( Figure 4 ) in rice flour and foreign matter.

[0138] The cyclone unit 940 is generally composed of a funnel-shaped lower body 942 and an upper body 944 coupled to the lower body 940 and generating a cyclone flow.

[0139] The upper body 944 is provided with an air circulation fan 948 that generates a forced flow to form an air circulation, and a windshield 946 that can prevent air leakage is provided at the joint of the upper body 944 and the air circulation fan 948. The air circulation fan 948 and the upper body 944 are connected by bolts. The windshield 946 is arranged between the air circulation fan 948 and the upper body 944. During the connection process of the air circulation fan 948 and the upper body 944, the gap between the air circulation fan 948 and the upper body 944 becomes narrow, resulting in the windshield 946 being pressed, thereby achieving an airtight seal.

[0140] The upper main body 944 is generally formed in a dome shape, including an air intake portion 944a that sucks air in the tangential direction of the upper main body 944 through the operation of the air circulation fan 948, and an air discharge portion 944b that extends vertically in the center of the upper main body 944 and discharges air to the axial upper portion of the cyclone portion 940. At this time, in order to guide the air flowing in through the air intake portion 944a to descend in a spiral shape, a spiral inclined surface 944d is formed in such a way that the height gradually decreases as it approaches the air flow direction from the upper surface portion 944c connected to the air intake portion 944a.

[0141] The above-mentioned air circulation intake connector 924 is connected to a cyclone intake hose 926 ( Figure 1 ).

[0142] On the other hand, when the air circulation fan 948 operates, a forced flow of internal and external circulation is generated in the rice washing chamber 802 ( Figure 4 ), passing through the air circulation intake port 838 formed in the stirring guide member 830, the air circulation intake hose 920, the air circulation intake connector 924, the cyclone intake hose 926, and being sucked into the cyclone portion 940 through the air intake portion 944a. The sucked air rotates and descends in a spiral shape, and foreign matters and rice powder included in the air descend together with the air. During the air descent process, it is discharged through the air discharge portion 944b, and the foreign matters and rice powder continue to fall along the lower main body 942 by their own weight and are discharged and trapped through the foreign matter discharge port 942a of the lower main body 942.

[0143] The air discharged through the air discharge portion 944b is discharged to the air circulation discharge path 930 formed in the rice bucket coupling portion 60 through the air circulation fan 948, and then passes through the air circulation discharge connector 914 and the air circulation discharge hose 910 and is discharged into the rice washing chamber 802 ( Figure 4 ) through the air circulation discharge port 836 of the stirring guide member 830. At this time, there is an air circulation discharge guide member 932 that guides the air discharged through the air circulation fan 948 to the air circulation discharge path 930. The air circulation discharge guide member 932 surrounds the outside of the air circulation fan 948, and one end is connected to the air circulation discharge path 930, guiding the air discharged through the air circulation fan 948 to uniformly move to the air circulation discharge path 930.

[0144] The air passes through the above path through the operation of the air circulation fan 948 and circulates inside and outside the rice washing chamber 802 ( Figure 4 ), and performs air flushing to brush off rice powder and foreign matters from the surface of the rice by using the strong air flow.

[0145] Figure 36It is a cross-sectional view showing a foreign matter discharge structure of a stirring outer cylinder of an automatic rice cooker with a rice washing function according to an embodiment of the present invention. Figure 37 It is a bottom view of a foreign matter discharge structure of a stirring outer cylinder of an automatic rice cooker with a rice washing function according to an embodiment of the present invention. Figure 38 It is an exploded perspective view of a flow path conversion unit of a foreign matter discharge structure of a stirring outer cylinder of an automatic rice cooker with a rice washing function according to an embodiment of the present invention.

[0146] As described above, the stirring outer cylinder 810 is provided with a foreign matter discharge port 814 for discharging foreign matters and rice flour shed from rice by physical friction. In order to smoothly discharge foreign matters and rice flour through the foreign matter discharge port 814, a discharge flow is blown toward the stirring outer cylinder 810 through a discharge flow inlet 813. Regarding the discharge flow, without providing an additional fan, the flow path of the discharge flow of the suction fan 80 is converted, thereby saving the number of components or installation space. The suction fan 80 is connected to a flow path conversion unit 880, and the flow path conversion unit 880 discharges the discharge flow of the suction fan 80 to the outside or to a discharge flow inlet hose 874 connected to the discharge flow inlet 813.

[0147] The flow path conversion unit 880 includes a box 882 having an outer appearance with two adjacent open faces, and a lid 884 coupled to the open upper surface of the box 882. On one face of the box 882, a discharge flow inlet 882a connected to the discharge port (not shown) of the suction fan 80 is formed, and on the other face, a discharge flow inlet hose connector part 882b coupled to the discharge flow inlet hose 874 is formed. One open face 882c discharges the discharge flow of the suction fan 80 to the outside. A flow path conversion rotor 886 is provided on the box 882, and a flow path conversion motor 888 for driving the flow path conversion rotor 886 is provided on the lid 884. The box 882 and the lid 884 are respectively provided with coupling holes 882e, 884e for screw coupling at corresponding positions and are coupled by screws connected to the coupling holes 882e, 884e. The flow path conversion rotor 886 includes a panel 886a and a rotation shaft 886b forming the center for rotating the panel 886a. The box 882 has a shaft hole 882d at the bottom surface for inserting the lower end of the rotation shaft 886b of the flow path conversion rotor 886, and the lid 884 has a through hole 884d through which the upper end of the rotation shaft 886b of the flow path conversion rotor 886 passes. In addition, the lid 884 has a coupling boss 884a formed to protrude upward for setting the flow path conversion motor 888 and having a thread formed inside. The flow path conversion motor 888 has a coupling flange 888a extending outward from the outer peripheral surface, and the coupling flange 888a and the coupling boss 884a are coupled by screws to fix the flow path conversion motor 888. At this time, the upper end of the rotation shaft 886b passing through the through hole 884d of the lid 884 is coupled to the motor shaft 888b of the flow path conversion motor 888, and the flow path conversion rotor 886 is rotated by the drive of the motor 888. When the flow path conversion rotor 886 rotates to seal the open face 882c, the discharge flow of the suction fan 80 flowing in through the discharge flow inlet 882a flows to the discharge flow inlet hose connector part 882b and flows into the discharge flow inlet 813 of the agitation outer cylinder 810 through the discharge flow inlet hose 874. When the flow path conversion rotor 886 rotates to seal the discharge flow inlet 882a, the open face 882c is opened, and the discharge flow of the suction fan 80 flowing in through the discharge flow inlet 882a is discharged to the outside through the open face 882c.

[0148] When the discharge flow of the suction fan 80 flows into the discharge flow inlet 813 through the flow path conversion of the flow path conversion unit 880 and through the discharge flow inlet hose 874, the discharge flow flows along the inner surface of the agitation outer cylinder 810, and sweeps out the foreign matters and rice flour discharged from the agitation inner cylinder 820 to the agitation outer cylinder 810 by physical friction and discharges them to the foreign matter discharge port 814. A foreign matter discharge pipe 872 is coupled to the foreign matter discharge port 814. The foreign matters discharged through the foreign matter discharge port 814 move to a first dust collecting bucket 892 described later through the foreign matter discharge pipe 872.

[0149] Figure 39 It is a foreign matter collection structure of a stirring component of an automatic rice cooker with a rice washing function according to an embodiment of the present invention.

[0150] A bottom plate 1a is coupled to the lower side of the base 1, and a stirring component 800 ( Figure 1 ) or an air circulation component 900 ( Figure 1 ) and other components are provided in the space defined by the base 1 and the bottom plate 1a. The bottom plate 1a is provided with a first foreign matter discharge hole 1b communicating with the foreign matter discharge pipe 872. Through the discharge flow of the suction fan 80, the foreign matter accumulated in the stirring outer cylinder 810 is collected into the first dust collecting bucket 892 through the foreign matter discharge port 814, the foreign matter discharge pipe 872, and the first foreign matter discharge hole 1b. At this time, the first dust collecting bucket 892 needs to be provided with an air discharge part 893 to discharge the discharge flow of the suction fan 80, and filters 893a and 893b are provided in the air discharge part 893 to prevent the foreign matter collected in the first dust collecting bucket 892 from being discharged to the outside. As long as it is a device that can filter the rice flour and foreign matter generated during the rice washing process without water, the number or type of the filter is not limited. In Figure 39 an embodiment of the present invention shown, it is composed of a primary filter 893a that discharges to the outside by filtering fine rice flour and a secondary filter 893b that filters the flow discharged through the primary filter 893a and filters relatively large rice flour or foreign matter.

[0151] At this time, regarding the primary filter 893a, in the case of using a washable filter, the user can separate it from the first dust collecting bucket 892 for cleaning, so it can be used more hygienically.

[0152] Figure 40 It is a foreign matter collection structure of an air circulation component of an automatic rice cooker with a rice washing function according to an embodiment of the present invention.

[0153] The bottom plate 1a is provided with a second foreign matter discharge port 1c communicating with the foreign matter discharge port 942a of the lower main body 942 provided in the cyclone part 940. The foreign matter and rice flour in the flow circulating in the rice washing chamber 802 ( Figure 4 ) are separated only downward in the cyclone part 940 and collected into the second dust collecting bucket 894.

[0154] Figure 41 It is a view showing a dust collecting bucket of an automatic rice cooker with a rice washing function according to an embodiment of the present invention.

[0155] For ease of use, the first dust collecting bucket 892 and the second dust collecting bucket 894 of an automatic rice cooker with a rice washing function according to an embodiment of the present invention are formed integrally. The first dust collecting bucket 892 and the second dust collecting bucket 894 are connected by a connecting portion 865. In addition, the first dust collecting bucket 892 and the second dust collecting bucket 894 are spaced apart from each other and connected by a connecting portion 895, and the first dust collecting bucket 892 and the second dust collecting bucket 894 each include a guiding rib 896 protruding in the direction of the space. The guiding rib 896 is coupled to the bottom plate 1a to guide the installation of the dust collecting bucket 890. The primary filter 893a is detachably provided in the first dust collecting bucket 892 in a mesh form and can be separated from the first dust collecting bucket for cleaning with water. The secondary filter 893b allows the flow passing through the primary filter 893a to pass through and is composed of a filter in the form of a non-woven fabric. The secondary filter 893b can also be separated from the first dust collecting bucket 892 for cleaning, but since it is made of a non-woven fabric material, it is difficult to clean with water and can physically remove rice powder and foreign substances.

[0156] Figure 42 FIG. is a view showing a structure for detaching and attaching a dust collecting bucket of an automatic rice cooker with a rice washing function according to an embodiment of the present invention.

[0157] As described above, a bottom plate 1a is provided on the lower side of the base 1, and a dust collecting bucket 890 is detachably provided on the bottom plate 1a.

[0158] As described above, the bottom plate 1a is formed with a first foreign matter discharge hole 1b and a second foreign matter discharge hole 1c, and the first dust collecting bucket 892 ( Figure 40 ) is coupled to the lower side of the first foreign matter discharge hole 1b, and the second dust collecting bucket 894 ( Figure 40 ) is coupled to the lower side of the second foreign matter discharge hole 1c. In order to couple the first dust collecting bucket 892 and the second dust collecting bucket 894, a first dust collecting bucket receiving portion 1d and a second dust collecting bucket receiving portion 1e are formed on the bottom plate 1a. A partition 1f is provided between the first dust collecting bucket receiving portion 1d and the second dust collecting bucket receiving portion 1e, and a guiding groove 1g for inserting the guiding ribs 896 of the first dust collecting bucket 892 and the second dust collecting bucket 894 is formed in the partition 1f to guide the detaching and attaching of the dust collecting bucket 890.

[0159] Figure 43 FIG. is a view showing a rod for opening and closing a rice discharging port of an automatic rice cooker with a rice washing function according to an embodiment of the present invention, Figure 44 FIG. is a view showing a state in which a rod of an automatic rice cooker with a rice washing function according to an embodiment of the present invention seals the rice discharging port, Figure 45 FIG. is a view showing a state in which a rod of an automatic rice cooker with a rice washing function according to an embodiment of the present invention opens the rice discharging port.

[0160] Refer to Figure 26 and Figures 43 to 45, a rod 860 for opening and closing the stirring outer cylinder 810, the stirring inner cylinder 820, and the rice discharging ports 815 and 825 is provided on the outer side surface of the stirring outer cylinder 810.

[0161] The stirring outer cylinder 810 and the stirring inner cylinder 820 are in close contact with each other in the regions 812 and 827 around the rice discharging ports, and the positions of the rice discharging ports 815 and 825 are aligned with each other. Therefore, the rice discharging ports 815 and 825 can be opened and closed by one rod 860.

[0162] The rod 860 has a main body 861 extending in length and width as a whole, and an opening and closing portion 862 that contacts the stirring outer cylinder 810 ( Figure 22 ) and the stirring inner cylinder 820 to open and close the rice discharging ports 815 and 825 is formed at the lower end portion of the main body 861. A sealing cover 863 is attached to the inner peripheral surface of the opening and closing portion 862 to improve airtightness. The opening and closing portion 862 is formed of the same metal material as the stirring inner cylinder 820. The sealing cover 863 has a plurality of bending portions 863a at the edge, and the bending portions 863a are bent so as to surround a part of the opening and closing portion 862, thereby combining the opening and closing portion 862 and the sealing cover 863. The rod 860 is provided on the outer peripheral surface of the stirring outer cylinder 810, and support shafts 864 for rotatably setting the rod 860 are provided on both sides of the main body 861. The stirring outer cylinder 810 has rod support portions 819 ( Figure 20 , 21) for combining the support shafts 864.

[0163] The rod 860 has a pressing portion 866 on the side opposite to the opening and closing portion 862 with reference to the support shaft 864. The pressing portion 866 is pressed by the operation of a driving device, and an electromagnetic valve 870 ( Figure 26 ) is used as the driving device in the embodiment. When the pressing portion 866 is pressed, the rod 860 rotates with reference to the support shaft 864, and the rice discharging ports 815 and 825 are opened by the opening and closing portion 862. At this time, even if the electromagnetic valve 870 ( Figure 26 ) retracts and the force pressing the pressing portion 866 is removed, the rod 860 does not rotate by itself and return to the original position. Therefore, in order to reseal the rice discharging ports 815 and 825, a spring 867 that provides a force in the direction opposite to the pressing direction of the electromagnetic valve 870 ( Figure 26 ) is provided to the rod 860. The rod 860 has a spring receiving portion 865 for receiving one end portion of the spring 867, and the opposite end portion of the spring 867 is supported by the outer side surface of the stirring outer cylinder 810. The stirring outer cylinder 810 has spring fixing protrusions 817 for inserting the spring 867.

[0164] In addition, when the rice washing process is completed, the stirring motor 842 ( Figure 26 ) rotates at a low speed (rice feeding mode), and as described above, the rod 860 is controlled by the electromagnetic valve 870 ( Figure 26) When the discharging ports 815 and 825 are opened by the rotation of [], the stirring blades 840 sweep the rice in the stirring inner cylinder 820 towards the discharging ports 815 and 825. Thus, a certain amount of the rice in the stirring inner cylinder 820 is dispersed and flows into the rice suction part 64. Refer to Figure 1 After that, the rice that has fallen into the rice suction part 64 by the operation of the suction fan 80 moves along the rice transfer pipe 94, then is poured into the inner pot 12 after passing through the cyclone rice separator 100 for cooking rice.

[0165] The above has described an example where the rice washing assembly is provided in the automatic rice cooker, but the rice washing assembly can be used alone or installed in the automatic rice bucket to implement the rice washing function.

[0166] Figure 46 is an exploded view of an automatic rice bucket equipped with a rice washing assembly according to an embodiment of the present invention, Figure 47 is an exploded view of a stirring assembly included in the rice washing assembly according to an embodiment of the present invention, Figure 48 is a longitudinal sectional view of an automatic rice bucket equipped with a rice washing assembly according to an embodiment of the present invention, Figure 49 is a view showing the stirring outer cylinder and the stirring guide member of the rice washing assembly according to an embodiment of the present invention, Figure 50 is a cross-sectional view of an automatic rice bucket equipped with a rice washing assembly according to an embodiment of the present invention.

[0167] The automatic rice bucket includes a base 1100 that forms the appearance, and a rice bucket 1200 is coupled to the upper side of the base 1100. A rice bucket coupling part 1150 for coupling the rice bucket 1200 is formed on the upper surface of the base 1100. A measuring part 1600 for measuring the discharged amount of rice is provided on the lower side of the rice bucket 1200 as needed, and when the measuring part 1600 is provided, the measuring part 1600 is coupled within the rice bucket coupling part 1150.

[0168] Similar to the above case applicable to the automatic rice cooker, the rice washing assembly includes: a rice washing chamber 1802 that receives rice from the rice bucket 1200 for washing rice; a stirring assembly 1800 that includes stirring blades 1840 that rotate within the rice washing chamber 1802 to physically rub the rice; and an air circulation assembly 1900 that provides an air rinsing function through air circulation. As described above, the rice washing chamber 1802 is a space formed by a stirring outer cylinder 1810, a stirring inner cylinder 1820 installed within the stirring outer cylinder 1810, and a stirring guide member 1830 installed on the upper surface of the stirring outer cylinder 1810.

[0169] On the other hand, the stirring assembly 1800 includes a stirring motor (not shown) that rotates the stirring blades 1840. The rotating shaft 1842 of the stirring motor (not shown) passes through the through hole 1812 of the outer stirring cylinder 1810 and the through hole 1822 of the inner stirring cylinder 1820 and is coupled to the stirring blades 1840. Through the rotation of the stirring blades 1840, the rice is rubbed, and the rice powder and foreign matters are shaken off from the surface of the rice. At this time, the inner stirring cylinder 1820 is provided with a plurality of discharge holes 1824 for discharging the rice powder and foreign matters shaken off from the rice by the rotation of the stirring blades 1840 to the outer stirring cylinder 1810, and the rice powder and foreign matters discharged through the discharge holes 1824 are accumulated in the outer stirring cylinder 1810.

[0170] On the other hand, in the same manner as the above case when applied to an automatic rice cooker, the air circulation assembly 1900 includes an air circulation fan 1948 and a cyclone unit 1940. The cyclone unit 1940 sucks air from the rice washing chamber 1802 through the forced flow of the air circulation fan 1948, separates foreign matters in the air using centrifugal force, and then discharges the air and foreign matters separately.

[0171] The cyclone unit 1940 includes: an air suction part 1944a that sucks air in the tangential direction of the cyclone unit 1940 through the operation of the air circulation fan 1948; an upper main body 1944 that has an air discharge part 1944b for discharging air to the upper part in the axial direction of the cyclone unit 1940; and a lower main body 1942 that is coupled to the upper main body 1944 and has a foreign matter discharge part 1942a for discharging foreign matters to the lower part in the axial direction of the cyclone unit 1940.

[0172] The air circulation fan 1948 and the upper main body 1944 are coupled by a coupling bolt. A wind deflector 1946 is disposed between the air circulation fan 1948 and the upper main body 1944. During the coupling process of the air circulation fan 1948 and the upper main body 1944, the gap between the air circulation fan 1948 and the upper main body 1944 becomes narrow and presses the wind deflector 1946 to achieve airtight sealing.

[0173] Whether to use a hose or not or whether to set up a pipeline can be changed according to whether the rice washing assembly is used alone or installed in other devices. However, the air suction part 1944a and the air discharge part 1944b of the air circulation assembly 1900 are connected to the rice washing chamber 1802, circulate air inside and outside the rice washing chamber 1802, separate the rice powder, and discharge it to the lower part of the cyclone unit 1940. A dust collection bucket 1894 that can be disassembled and installed on the base 1100 is provided on the lower side of the cyclone unit 1940, whereby the separated rice powder can be discarded. For the convenience of setting, the air suction part 1944a and the air discharge part 1944b of the air circulation assembly 1900 are preferably connected to the stirring guide member 1830, and a hose, a pipe, etc. can be used for the connection.

[0174] As Figures 46 to 50As shown, in the case of the rice washing component being applicable to the automatic rice bucket, the stirring guide member 1830 is formed with a rice pouring hole 1832 for pouring rice into the rice washing chamber 1802, an air circulation discharge port 1836 for discharging air from the air circulation component 1900 into the rice washing chamber 1802, and an air circulation suction port 1838 for sucking air from the rice washing chamber 1802 into the air circulation component 1900.

[0175] On the other hand, the stirring component 1800 is detachably provided on the base 1100. After leading out the stirring component 1800 from the base 1100 and separating the stirring guide member 1830 from the stirring outer cylinder 1810, the washed rice is moved to other places for loading. At this time, in order to easily detach and attach the stirring component 1800 from the base 1100, a sliding support table 1300 for installing the stirring outer cylinder 1810 is provided.

[0176] When separating the stirring component 1800 from the base 1100, it is necessary to separate the air circulation suction port 1838 and the air circulation discharge port 1836 from the air circulation component 1900. When combining the stirring component 1800 with the base 1100, it is necessary to combine the air circulation suction port 1838 and the air circulation discharge port 1836 with the air circulation component 1900. For this purpose, the base 1100 is provided with an air circulation discharge channel 1910 that is connected to the air circulation discharge port 1836 when the stirring component 1800 and the base 1100 are combined and connects the air circulation discharge port 1836 and the air circulation component 1900. The base 1100 is provided with an air circulation suction channel 1920 that is connected to the air circulation suction port 1838 when the stirring component 1800 and the base 1100 are combined and connects the air circulation suction port 1838 and the air circulation component 1900.

[0177] At this time, the air circulation discharge port 1836 and the air circulation suction port 1838 are formed by being bent into an L shape, and the upper end portions are preferably formed horizontally with respect to the sliding direction of the stirring assembly 1800. When the upper end portions of the air circulation discharge port 1836 and the air circulation suction port 1838 are formed horizontally with respect to the sliding direction of the stirring assembly 1800, when the stirring assembly 1800 is slidably coupled to the base 1100, the air circulation discharge port 1836 and the air circulation suction port 1838 are respectively naturally coupled to the air circulation discharge passage 1910 and the air circulation suction passage 1920. At this time, the air circulation discharge passage 1910 and the air circulation suction passage 1920 are provided with sealing members 1912 and 1922 at the ends, so as to prevent air leakage when connecting the air circulation discharge port 1836 and the air circulation suction port 1838. At this time, the air circulation discharge port 1836 and the air circulation suction port 1838 are bent into an L shape. In order to accurately connect to the ends of the air circulation discharge passage 1910 and the air circulation suction passage 1920 in terms of direction, the stirring outer cylinder 1810 and the stirring guide member 1830 are respectively provided with guide grooves 1819 and guide protrusions 1839 that can be directionally coupled.

[0178] At this time, the air circulation suction passage 1920 and the air circulation discharge passage 1910 are respectively connected to the air suction portion 1944a and the air discharge portion 1944b of the air circulation assembly 1900. At this time, the air discharge portion 1944b and the air circulation discharge passage 1910 are not directly connected, and an air circulation fan 1948 for generating flowing air is provided on the upper side of the air discharge portion 1944b. Therefore, the air circulation discharge passage 1910 is connected to the air circulation fan 1948.

[0179] Therefore, the air suction portion 1944a and the air discharge portion 1944b are arranged at different heights, whereby the heights of the ends of the air circulation suction passage 1920 and the air circulation discharge passage 1910 coupled to the air circulation assembly 1900 are different. Therefore, the height of the end of the air circulation discharge passage 1910 coupled to the air circulation assembly 1900 is different from the height of the end coupled to the air circulation discharge port 1936, and the air circulation discharge passage 1910 is inclined. Thus, the air circulation suction passage 1920 is arranged below the air circulation discharge passage 1910, so it has the advantage of being able to further miniaturize the size of the rice washing assembly.

[0180] On the other hand, due to reasons of the setting angle, when it is difficult to directly connect the air suction portion 1944a and the air circulation suction passage 1920, a connector 1930 can be provided separately.

[0181] Preferably, a dust collection bucket 1894 for collecting foreign matters discharged from the cyclone portion is provided below the lower main body of the cyclone portion, and the dust collection bucket is detachably provided to easily pour out the discharged foreign matters.
