When the upper cover plate 120 is closed, the spray nozzle 1052 is located directly above the feeding device 10. The spray switch 1053 is connected to the controller in communication, so as to be opened or closed according to the control instruction of the controller, so as to realize high-pressure spraying of the feeding device 10. The spray nozzle 1052 includes a plurality of high-pressure spray nozzles, so that the inner wall of the feeding device 10 can be effectively washed.

[0081] It can be seen that the intelligent cooking machine provided in the present embodiment utilizes a hollow shell to form a sealed cooking cavity 101, and a working space for accommodating main cooking equipment is provided inside the cooking cavity 101. The intelligent cooking machine provided in the present embodiment is constructed with a feeding cooking system and a flushing system with the cooking cavity as the core combination. Both the feeding cooking heating system and the flushing system are mainly composed of a main cooking equipment arranged inside the cooking cavity and an auxiliary cooking equipment arranged outside the cooking cavity. A connecting port connecting the inside and outside of the cooking cavity is provided on the shell 100 corresponding to the main cooking equipment. The auxiliary cooking equipment placed outside the cooking cavity is connected to the corresponding main cooking equipment arranged inside the cooking cavity through the corresponding connecting port to realize the corresponding feeding cooking or flushing function.

[0082] Among them, Figure 2 , Figure 3a and Figure 3b As shown, the feeding cooking and heating system is mainly composed of a feeding device 10, a wok device 103 and a dish dispensing device 104 arranged inside the cooking cavity 101. Among them, the cooking cavity 101 is provided with a feeding area for accommodating the feeding device 10, a cooking area for accommodating the wok device and a dish dispensing area for accommodating the dish dispensing device from top to bottom. When it is necessary to feed and cook, firstly, the feeding device 10 is used to import and add the food packaging box carrying the food into the feeding bin 11 (at this time, the feeding device 10 is in a state where the lower hopper 13 is on the top and the upper bin 11 is on the bottom). Then the corresponding cooking program is started. During the cooking process, the feeding device 10 is flipped to a state where the lower hopper 13 is on the bottom and the upper bin 11 is on the top under the action of the feeding mechanism flipping mechanism, so that the food in the food packaging box introduced into the upper bin 11 falls onto the bin door at any time when the feeding device 10 is flipped. The pot body 1031 is turned to the unloading station under the action of the pot body turning device 1033, where the pot mouth faces the loading device 10. The corresponding door is opened by the door driving mechanism to allow the food to fall into the pot body 1031 for subsequent heating and stir-frying (the pot body 1031 rotates around its own central axis under the drive of the pot body rotating device 1035 to stir-fry the food in the pot body 1031, and stir-frying parts such as stir-frying tendons are provided in the pot body 1031). After the cooking is finished, the pot body 1031 is turned over to the dish serving station (the pot mouth faces the dish plate 900 in the dish serving area) to serve the food.

[0083] Return to reference Figure 1The flushing system is mainly composed of a feeding device 10, a frying pan device 103 and a spraying device 105 arranged inside the cooking cavity 101. Specifically, the top and bottom of the feeding device 10 are provided with openings communicating with the cavity inside of the feeding device 10. When the feeding device 10 is flushed by the spray nozzle 1052 of the spraying device 105, the water sprayed by the spray nozzle 1052 flushes the cavity inside of the feeding device 10 through the top opening of the feeding device 10, and then flows out through the bottom opening of the feeding device 10. Among them, before flushing the feeding device 10 through the spray nozzle 1052, the pot body 1031 is first flipped under the drive of the pot body flipping device 1033 so that the pot mouth 10 is opposite to the spray nozzle 1052 and the feeding device 10. Then, when flushing the feeding device 10 through the spray nozzle 1052, the water sprayed by the spray nozzle 1052 flushes the inside of the cavity of the feeding device 10 through the top opening of the feeding device 10, flows out through the bottom opening of the feeding device 10 and falls into the pot body 1031 through the pot mouth of the pot body 1031, so as to indirectly flush the inner cavity of the pot body 1031 (in the process of indirectly flushing the inner cavity of the pot body 1031, the pot body 1031 rotates around its own central axis driven by the pot body rotating device 1035 to cooperate with the flushing). After the internal cavity of the feeding device 10 and the pot body 1031 is flushed by the spray nozzle 1052, the pot body 1031 is flipped to a position (water pouring position) with the pot mouth facing the bottom opening of the cooking cavity 101 under the drive of the pot body flipping device 1033, so that the flushed water is poured out and falls into the bottom opening 1010 of the cooking cavity 101 for discharge (when the pot body 1031 is at the water pouring position, it is preferred that a wok spray nozzle is provided inside the cooking cavity 101 of the cooking machine to directly spray the inner wall of the pot body 1031, and the pot body 1031 rotates around its own central axis under the drive of the pot body rotating device 1035 to cooperate with direct spraying and flushing). The bottom opening 1010 of the cooking cavity 101 is connected to the inlet of the food waste disposer 106, and the outlet of the food waste disposer 106 is connected to the drain port 200 provided on the cooking machine housing. The embodiment of the present invention arranges a food waste disposer at the bottom opening of the cooking cavity to treat the sewage before discharging it, thereby improving the filtering efficiency and avoiding the arbitrary discharge of waste water, thereby avoiding the pollution of the kitchen sanitary environment.

[0084] Below, the specific structure of an improved feeding device 10 proposed in the present invention will be described in detail through multiple embodiments. The improved feeding device 10 can be applied to the intelligent cooking machine of the above-mentioned embodiment to participate in realizing the cooking or rinsing functions, and the improved feeding device 10 is improved on the structure of the existing feeding device, which can effectively overcome the technical problems existing in the existing feeding device.

[0085] like Figures 4 to 6 As shown, an embodiment of the present invention provides a feeding device 10, which includes a feeding bin 11 for receiving a food packaging box 800, a supporting frame 12, a bin door control mechanism 16, a lower hopper 13, a feeding device flipping mechanism 14 for flipping the feeding device 10 upside down as a whole, and a position detection device 15 for detecting the flipping position (angle) of the feeding device 10 as a whole. One of the improvements of the embodiment of the present invention is to introduce the supporting frame 12 formed by integral injection molding, and the feeding bin 11, the lower hopper 13, the bin door control mechanism 16, the feeding device flipping mechanism 14 and the position detection device 15 are reasonably connected and assembled together through the supporting frame 12 to form the entire feeding device 10 to achieve the corresponding function, which is easier to assemble, simple in structure, and more stable after assembly. The specific structure of the supporting frame 12 provided in this embodiment and the connection relationship between it and other components are described in detail below in conjunction with the accompanying drawings.

[0086] Combination Figures 4 to 9 As shown, the supporting skeleton 12 provided in this embodiment includes a supporting skeleton main body 121 that is integrally injection-molded, and the supporting skeleton main body 121 is a frame structure with at least one discharge port 1210 provided in the center, and the at least one discharge port is connected to the top end face 1211 and the bottom end face 1212 of the supporting skeleton main body 121, wherein the one end face of the supporting skeleton main body 121 used to connect to the upper bin 11 is the top end face 1211 of the supporting skeleton main body 121, and the other end face of the supporting skeleton main body 121 used to connect to the lower hopper 13 is the bottom end face 1212 of the supporting skeleton main body 121, and the top end face 1211 and the bottom end face 1212 of the supporting skeleton main body 121 are two end faces of the supporting skeleton main body 121 facing opposite directions.

[0087] It can be understood that the feeding opening 1210 provided at the center of the supporting skeleton body 121 provided in this embodiment is matched with the compartment for accommodating food in the food packaging box 800 received by the upper bin 11. When the compartment of the food packaging box 800 is one compartment, the feeding opening 1210 provided at the center of the supporting skeleton body 121 corresponds to one. When the compartment of the food packaging box 800 is multiple compartments, the feeding opening 1210 provided at the center of the supporting skeleton body 121 corresponds to multiple.

[0088] In one embodiment, in order to match a standard four-compartment (four compartments of the same size) food packaging box 800, the feed opening 1210 provided at the center of the supporting skeleton body 121 corresponds to four feed openings 1210 of the same size.

[0089] In another embodiment, Figure 7 As shown, in order to match the food packaging box 800 with four compartments of different sizes, the feed opening 1210 provided at the center of the supporting skeleton body 121 includes four, namely the first feed opening 1210a, the second feed opening 1210b, the third feed opening 1210c and the fourth feed opening 1210d, and the sizes of the first feed opening 1210a, the second feed opening 1210b, the third feed opening 1210c and the fourth feed opening 1210d correspond to the sizes of the four compartments of the food packaging box 800.

[0090] For further information, please refer to Figure 7The supporting skeleton body 121 includes an outer frame 1213 and a central arm 1214. The central arm 1214 is disposed at the center of the supporting skeleton body 121 and connected to the outer frame 1213 to form a feed opening 1210. Specifically, the outer frame 1213 is mainly composed of a front frame 1213a, a right frame 1213b, a rear frame 1213c and a left frame 1213d connected end to end in sequence, wherein the front frame 1213a and the rear frame 1213c are opposite to each other, and the right frame 1213b and the left frame 1213d are opposite to each other. The central arm 1214 includes a transverse arm 1214a, a first longitudinal arm 1214b and a second longitudinal arm 1214c. The two ends of the transverse arm 1214a are fixedly connected to the right frame 1213b and the left frame 1213d respectively. The two ends of the first longitudinal arm 1214b are connected to the front frame 1213a and the transverse arm 1214a respectively. The two ends of the second longitudinal arm 1214c are connected to the transverse arm 1214a and the rear frame 1213c respectively. The outer frame 1213 has a plane structure (the outer frame top surface 12139) on the top end surface 1211 of the supporting skeleton body 121, which is used to be connected to the upper bin 11. The outer frame 1213 has a groove structure on the bottom end surface 1212 of the supporting skeleton body 121. Specifically, the outer frame 1213 is located at the bottom end surface 1212 of the supporting skeleton body 121 and includes a frame inner edge 12135 and a frame outer edge 12136 respectively connected to the bottom wall of the outer frame, and the frame inner edge 12135 and the frame outer edge 12136 constitute a receiving groove 12138 of the supporting skeleton body 121. It can be understood that the receiving groove 12138 is distributed in the front frame 1213a, the right frame 1213b, the rear frame 1213c and the left frame 1213d and is connected end to end. The receiving groove 12138 constitutes an electrical wiring groove of the feeding device 10.

[0091] Further, the frame outer edges 12136 of the middle positions of the right frame 1213b and the left frame 1213d extend outwards to form the right lug 12130b and the left lug 12130d. The center positions of the right lug 12130b and the left lug 12130d are respectively provided with a drive shaft sleeve 124 and a rotating shaft sleeve 125, the drive shaft sleeve 124 and the rotating shaft sleeve 125 are both integrally injection molded with the supporting skeleton body 121, and the central axes of the drive shaft sleeve 124 and the rotating shaft sleeve 125 are located on the same axis. Specifically, the rotating shaft sleeve 125 is arranged in the receiving groove of the left lug 12130d, and the frame outer edge 12136 of the left frame 1213d is provided with a rotating shaft opening 1250 corresponding to the rotating shaft sleeve 125, and the position detection device 15 is connected to the rotating shaft sleeve 125 through a rotating shaft 150. Specifically, one end of the rotating shaft 150 is connected to the position detection device 15, and the other end passes through the rotating shaft opening 1250 to be connected to the rotating shaft sleeve 125. Correspondingly, the driving shaft sleeve 124 is arranged in the receiving groove of the right lug 12130b, and the frame outer edge 12136 of the right frame 1213b is provided with a driving shaft opening 1240 corresponding to the driving shaft sleeve 124, and the feeding device flipping mechanism 14 is connected to the driving shaft sleeve 124 through a driving shaft 140. The feeding device flipping mechanism 14 is preferably a driving motor. Specifically, one end of the driving shaft 140 is connected to the driving motor, and the other end passes through the driving shaft opening 1240 to be connected to the driving shaft sleeve 124. Since the central axes of the rotating shaft sleeve 125 and the driving shaft sleeve 124 are located on the same axis, the central axes of the rotating shaft 150 and the driving shaft 140 are correspondingly located on the same axis. Therefore, when the driving motor drives the entire feeding device 10 to flip through the driving shaft 140, the entire feeding device 10 can be stably flipped around the central axis position of the rotating shaft 150 and the driving shaft 140, so that the flipping process is more stable, and the position detection device 15 detects the flipping position state of the feeding device 10 more accurately. Preferably, the driving shaft 140 adopts a hexagonal shaft, the driving shaft sleeve 124 corresponds to a hexagonal sleeve, and the driving shaft opening 1240 corresponds to a regular hexagon matching the outer contour of the driving shaft 140. The rotating shaft 150 is a hollow shaft, and the other end of the rotating shaft sleeve 125 opposite to the rotating shaft opening 1250 is provided with another opening, and the electrical wires in the feeding device 10 that are routed through the receiving groove 12138 are uniformly passed through the other opening of the rotating shaft sleeve 125 and the rotating shaft 150 to pass out of the feeding device 10. In addition, the receiving grooves of the left lug 12130d and the right lug 12130b are also used to receive and fix the door switch of the door control mechanism (described in detail later).

[0092] Combined with reference Figure 5 , Figure 6 and Fig.17 The door control mechanism 16 provided in this embodiment includes a door plate 161, a door shaft 162, and a door switch 163. The door plate 161 is rotatably mounted on the door shaft 162, and is mounted on the supporting skeleton body 121 through the door shaft 162, and each door plate 161 is used to close or open one of the feed openings 1210 (each feed opening 1210 corresponds to a compartment of the food packaging box 800), one door plate 161 is correspondingly provided with one door switch 163, and each door switch 163 controls the closing and opening of one of the door plates 161, and when the corresponding door plate 161 is opened, the food in the compartment of the food packaging box 800 corresponding to the door plate 161 falls through the corresponding feed opening 1210, thereby realizing the feed unloading operation.

[0093] In one embodiment, each of the door panels 161 is provided with a corresponding door shaft 162 to be installed on the supporting frame body 121. However, in this embodiment, when there are multiple door panels 161, for example, when four door panels 161 are provided corresponding to four material discharge ports, each door panel 161 is connected to a corresponding door shaft 162, that is, a total of four door shafts 162 need to be provided, and then the four door shafts 162 are respectively installed on the supporting frame body 121, which is more troublesome to install.

[0094] In another preferred embodiment, in order to improve the above installation trouble problem, at least two door panels 161 can be rotatably mounted on the same door shaft 162, and mounted on the supporting frame body 121 through the same door shaft 162. For example, Figure 6 and Fig.17 As shown, the door panels 161 provided in this embodiment include four, namely, the first door panel 161a, the second door panel 161b, the third door panel 161c and the fourth door panel 161d, and the first door panel 161a, the second door panel 161b, the third door panel 161c and the fourth door panel 161d are respectively arranged corresponding to the first material discharge port 1210a, the second material discharge port 1210b, the third material discharge port 1210c and the fourth material discharge port 1210d. The door shaft 162 includes two, namely, the first door shaft 162a and the second door shaft 162b, wherein the first door panel 161a and the second door panel 161b are both rotatably mounted on the first door shaft 162a, and the third door panel 161c and the fourth door panel 161d are both rotatably mounted on the second door shaft 162b.

[0095] The two ends of the first door shaft 162a and the second door shaft 162b are respectively connected and fixed to the supporting frame body 121. Specifically, the right frame 1213b and the left frame 1213d are respectively provided with door shaft through holes on the frame inner edge 12135 close to the front frame 1213a, and the two ends of the first door shaft 162a pass through the door shaft through holes to be fixed to the supporting frame body 121, and are arranged parallel to the frame inner edge 12135 of the front frame 1213a. Similarly, the right frame 1213b and the left frame 1213d are respectively provided with door shaft through holes on the frame inner edge 12135 close to the rear frame 1213c, and the two ends of the second door shaft 162b pass through the door shaft through holes to be fixed to the supporting frame body 121, and are arranged parallel to the frame inner edge 12135 of the rear frame 1213c.

[0096] Furthermore, one end of each of the door panels 161 is provided with a door panel shaft sleeve 1611 to pass through the door shaft 162, and the other end of each of the door panels 161 is a movable end 1612 that can rotate around the door shaft 162. The movable end 1612 of each of the door panels 161 is controlled by a door switch 163 to be opened or closed.

[0097] As an example, Figure 6 As shown, the door switch 163 provided in this embodiment includes four, namely, the first door switch 163a, the second door switch 163b, the third door switch 163c and the fourth door switch 163d, and the first door switch 163a, the second door switch 163b, the third door switch 163c and the fourth door switch 163d are respectively arranged corresponding to the first door plate 161a, the second door plate 161b, the third door plate 161c and the fourth door plate 161d. Specifically, the first door switch 163a and the third door plate 161c are received and fixed in the receiving groove of the left lug 12130d and are respectively located on both sides of the shaft sleeve 125. Similarly, the second door switch 163b and the fourth door switch 163d are received and fixed in the receiving groove of the right lug 12130b and are respectively located on both sides of the drive shaft sleeve 124.

[0098] The structure of each door switch 163 provided in this embodiment is the same. The structure and working principle of the door switch 163 are described below by taking the first door switch 163a as an example. Figure 6As shown, the first door switch 163a includes a push-pull electromagnet and a door lock tongue 1631, and plug-in holes are correspondingly provided on the inner edges 12135 of the right frame 1213b and the left frame 1213d, and one end of the door lock tongue 1631 can pass through the plug-in hole to support the corresponding movable end 1612 of the first door plate 161a. The push-pull electromagnet includes an electromagnet 1632 and an iron core 1633, a door lock tongue 1631 is arranged at one end of the iron core 1633 extending out of the electromagnet 1632, and the iron core 1633 is provided with a positioning ring 1634 near the door lock tongue 1631, and the iron core 1633 is directly sleeved with a return spring 1635 between the positioning ring 1634 and the electromagnet 1632. It should be noted that the door lock tongue 1631 can be in the form of an end of the iron core 1633 extending out of the electromagnet 1632 that can directly constitute the door lock tongue 1631, or an end of the iron core 1633 extending out of the electromagnet 1632 is connected or sleeved with another component to form the door lock tongue 1631. The appropriate form can be selected according to the actual situation; the push-pull electromagnet and the controller Electrical connection, when the controller receives the signal to control the push-pull electromagnet to be energized, the generated magnetic field can magnetize the iron core 1633, and the iron core 1633 forms a superimposed magnetic field. The directionality of the magnetic field generates force, and one end of the iron core 1633 can drive the door lock tongue 2311 to do displacement movement, thereby controlling the door lock tongue 1631 to be withdrawn in the direction of the electromagnet 1632 to leave the movable end 1612 of the first door plate 161a. Due to the loss of support from the door lock tongue 1631, the movable end 1612 of the first door plate 161a can rotate around the door shaft 162 under the action of its own gravity, thereby opening the first discharge port 1210a, so that the food in the compartment of the food packaging box 800 can fall through the first discharge port 1210a to achieve discharge. It can be understood that after the door plate 161 opens the discharge port 1210 to complete the discharge operation, the supporting frame body 121 is flipped over to make the door plate 161 fall back by its own weight to close the discharge port 1210, and then the push-pull electromagnet is closed by the controller. The iron core 1633 can extend in the direction away from the electromagnet 1632 under the reset action of the reset spring 1635, thereby driving the door lock tongue 2311 to reset to support the movable end 1612 of the first door plate 161a.

[0099] It can be understood that the wires used for each push-pull electromagnet to achieve electrical connection with the controller are routed through the receiving groove and finally pass through the rotating shaft 150 to the outside of the feeding device 10 to connect to the controller.

[0100] It can be understood that in the door control mechanism 16 provided in this embodiment, each door plate 161 is provided with a door switch 163 to control its closing or opening. By connecting the push-pull electromagnet of the door switch 163 to the controller, the controller controls the operation of each push-pull electromagnet, thereby controlling the opening time and sequence of each door plate 161, and further controlling the time and sequence of placing the ingredients in different compartments in the food packaging box 800. When the feeding device 10 provided in this embodiment is applied to the above-mentioned intelligent cooking machine, the controller of the intelligent cooking machine performs the unloading operation according to the corresponding recipe instructions, thereby controlling the time and sequence of placing the ingredients in different compartments in the food packaging box 800 according to the recipe instructions.

[0101] refer to Figure 4 , Figure 5 , Figure 6 and Fig.10 The feeding device 10 provided in this embodiment includes the feeding bin 11, which is a shell structure. One end face of the feeding bin 11 used for connecting with the supporting frame 12 is the bottom end face 111 (bottom) of the feeding bin 11, and the other end face of the feeding bin 11 away from the bottom end face 111 is the top end face 112 (top) of the feeding bin 11. A packaging box receiving space 110 is provided in the feeding bin 11, and the feeding bin 11 is mainly composed of a top wall 113 and a left side wall 114, a right side wall 115 and a rear side wall 116 connected to the top wall 113, wherein the left side wall 114 and the right side wall 115 are opposite. The inner cavity of the shell after the top wall 113, the left side wall 114, the right side wall 115 and the rear side wall 116 are connected constitutes the packaging box receiving space 110. In this embodiment, the front side of the upper material bin 11 opposite to the rear side wall 116 is an open structure, and the bottom side opposite to the top wall 113 is also an open structure. Among them, the opening on the front side constitutes a feed port for the food packaging box 800 for storing food to enter and exit, which is conducive to introducing the food packaging box 800 into the packaging box receiving space 110 or exporting it from the packaging box receiving space 110. The opening at the bottom is connected to the discharge port 1210 on the supporting frame 12, which is conducive to each compartment of the food packaging box 800 introduced into the packaging box receiving space 110 and each discharge port 1210 correspondingly connected. When the food packaging box 800 is received in the packaging box receiving space, the compartment opening of the food packaging box is consistent with the bottom opening of the upper material bin 11 for connecting to the supporting frame 12.

[0102] It can be understood that the bottom end surface 111 of the upper material bin 11 is located at the bottom of the upper material bin 11, and the bottom end surface 111 is matched with the outer frame top surface 12139 of the supporting skeleton body 121 to achieve connection, thereby achieving the connection between the upper material bin 11 and the supporting skeleton 12. Specifically, a plurality of assembly positions are distributed correspondingly on the bottom end surface 111 of the upper material bin 11 and the outer frame top surface 12139 of the supporting skeleton body 121, and the upper material bin 11 is connected and fixed to the supporting skeleton 12 by connecting parts such as screws at the assembly positions.

[0103] When implementing the present invention, the inventor discovered that in the feeding device provided by the prior art, for example, Chinese invention patent application No. CN201510152657.4 discloses an automatic feeding device suitable for a fully automatic cooking machine, in which a receiving space for receiving the food packaging box is composed of two side guide plates in a shell and a limit baffle plate arranged on the bottom surface of the shell, and the protrusions on the two outer sides of the food packaging box are installed in the feeding device along the positioning grooves of the two side guide plates. When the front end surface of the food packaging box is against the limit baffle plate, the protrusions on the two outer sides of the food packaging box cooperate with the positioning grooves of the two side guide plates to lock it in the receiving space. The existing design has at least the following two problems: (1) the food packaging box cannot be completely locked in the receiving space of the shell by simply relying on the protrusions on the two outer sides of the food packaging box and the positioning grooves of the two side guide plates. As a result, when the feeding device is flipped, the food packaging box is easily moved in the opposite direction of the food packaging box entering the receiving space, causing part of the food in the food packaging box to be spilled out, causing waste and failing to achieve normal feeding; (2) the receiving space for receiving the food packaging box is composed of the two side guide plates in the shell and the limit baffle plate provided on the bottom surface of the shell, that is, the compartment height of the food packaging box must match the height limited by the positioning grooves of the two side guide plates and the limit baffle plate on the bottom surface of the shell, that is, the receiving space can only import and receive food packaging boxes with a fixed (single) depth capacity size, and cannot import food packaging boxes with different depth capacity sizes.

[0104] In this regard, the embodiment of the present invention provides an improved loading bin structure and loading device, which can effectively solve the above two problems. Figure 6 , Fig.11 and Fig.12The inner walls of the left side wall 114 and the right side wall 115 of the upper material bin 11 are respectively provided with grooves (1140, 1150) which are recessed in a direction away from the bottom end surface 111 at positions close to the bottom end surface 111 (i.e., the connection surface between the upper material bin 11 and the supporting frame 12). Correspondingly, the corresponding positions of the inner surfaces of the flanges of the left and right side walls of the food packaging box 800 received in the upper material bin 11 are respectively provided with first protrusions 801 which are protruded in a direction away from the bin opening of the food packaging box 800 (reference Figure 13a to Figure 14b ). When the food packaging box 800 is accommodated in the receiving space 110 of the upper material bin 11, the first protrusions 801 on the flanged positions of the left and right side walls of the food packaging box 800 are snapped into the grooves (1140, 1150) on the inner walls of the left side wall 114 and the right side wall 115 of the upper material bin 11. Due to the limiting effect of the grooves (1140, 1150) on the first protrusions 801, the food packaging box 800 can be completely locked in the receiving space 110 of the upper material bin 11, preventing the food packaging box 800 from moving back and forth in the pushing direction during the flipping process of the feeding device 10, thereby effectively preventing part of the food from being spilled during the flipping process of the feeding device 10 and ensuring the normal feeding operation. In addition, the distance between the bottom end surface 111 of the loading bin 11 and the top end surface 112 of the loading bin 11 constitutes the maximum accommodation height of the accommodation space 110 of the loading bin 11. Since the food packaging box 800 is completely locked and accommodated in the accommodation space 110 of the loading bin 11 by snapping the first protrusion 801 provided therein into the groove (1140, 1150) at the corresponding position of the loading bin 11, the loading device 10 provided in this embodiment does not require that the depth capacity size of the accommodated food packaging box 800 needs to be uniquely matched with the height of the accommodation space. As long as the compartment depth of the food packaging box 800 is less than the maximum accommodation height of the accommodation space 110, it can be accommodated in the accommodation space 110 of the loading device 10. In other words, the loading device 10 provided in this embodiment can be used to receive food packaging boxes 800 with compartments of different capacity heights, and has a wider applicability.

[0105] As a preferred design, please continue to refer to Figure 6 , Fig.11 and Fig.12The grooves (1140, 1150) on the inner walls of the left side wall 114 and the right side wall 115 of the upper material bin 11 are preferably arranged at a position adjacent to the rear side wall 116, so that when the food packaging box 800 is pushed into the upper material bin 11 and the rear end surface of the food packaging box 800 abuts against the rear side wall 116 of the upper material bin 11, the first protrusions 801 on the flanged positions of the left and right side walls of the food packaging box 800 are just snapped into the grooves (1140, 1150) on the inner walls of the two sides of the upper material bin 11, thereby locking the food packaging box 800 in the accommodating space 110 of the upper material bin 11.

[0106] In addition, as a further design, in order to better guide the food packaging box 800 into the upper bin 11 so that the first protrusion 801 is snapped into the groove (1140, 1150), the inner walls of the left side wall 114 and the right side wall 115 of the upper bin 11 are also symmetrically provided with guide grooves (1141, 1151) connected to the grooves (1140, 1150), wherein the guide groove 1141 is connected to the groove 1140, and the guide groove 1151 is connected to the groove 1150. The guide groove 1141 and the guide groove 1151 have the same structure, and the structure of the guide groove 1141 is described below by taking the guide groove 1141 as an example. Fig.11 As shown, the guide groove 1141 includes an inclined guide portion 1141a and a transition portion 1141b, one end of the transition portion 1141b is connected to the groove 1140, and the other end of the transition portion 1141b is transitionally connected to one end of the inclined guide portion 1141a, and the other end of the inclined guide portion 1141a extends to the front opening of the upper bin 11. The surface of the transition portion 1141b is a horizontal plane, and the horizontal plane where the surface of the transition portion 1141 is located is higher than the lowest end of the correspondingly connected groove (1140, 1150). The surface of the inclined guide portion 1141a is an inclined surface, and gradually tilts upward from the other end of the inclined guide portion 1141a to one end of the inclined guide portion 1141a. Correspondingly, the inner surfaces of the flanges of the left and right side walls of the food packaging box 800 are close to the corresponding positions of the first protrusion 801, and are respectively provided with second protrusions 802 (reference) protruding in the direction away from the bin opening of the food packaging box 800. Figure 13a to Figure 14b ). And the height of the second protrusion 802 is less than the height of the first protrusion 801. In this way, when the food packaging box 800 is introduced into the upper material bin 11, the food packaging box 800 is placed along the Fig.11The food packaging box 800 is pushed into the upper material bin 11 in the direction of arrow A shown in the figure, and the first protrusion 801 and the second protrusion 802 on the flanged positions of the left and right side walls of the food packaging box 800 are respectively attached and move along the guide grooves (1141, 1151) of the left side wall 114 and the right side wall 115 of the upper material bin 11. Under the guidance of the guide grooves (1141, 1151), the food packaging box 800 can be effectively and quickly guided into place. When the food packaging box 800 is guided into place, the first protrusions 801 on both sides of the food packaging box 800 are buckled In the grooves (1140, 1150) on the inner walls on both sides of the upper material bin 11, the second protrusions 802 on both sides of the food packaging box 800 also just abut against the transition parts of the guide grooves (1141, 1151) on the inner walls on both sides of the upper material bin 11 and fit with their surfaces, thereby increasing the contact area between the food packaging box 800 and the inner walls on both sides of the upper material bin 11, so that the food packaging box 800 can be more securely accommodated in the upper material bin 11, thereby further preventing the food packaging box 800 from moving in the horizontal direction during the flipping of the upper material bin 11. In addition, when the food packaging box 800 needs to be taken out from the loading bin 11, it is only necessary to manually lift the food packaging box 800 upward (in the vertical direction) to avoid the obstruction of the groove (1140, 1150) to the first protrusion 801, and then pull it out, and guide the food packaging box 800 in the opposite direction along the guide groove (1141, 1151).

[0107] Preferably, the flanges of the left and right side walls of the food packaging box 800 and the top surface of the food packaging box 800 (the end surface where the bin opening is located) are both planar structures and are on the same horizontal plane, so as to facilitate the introduction of the food packaging box 800 into the upper bin 11. It can be understood that when the food packaging box 800 is completely accommodated in the accommodation space 110 of the upper bin 11, the top surface of the food packaging box 800 is slightly lower than the bottom end surface 111 of the upper bin 11.

[0108] Combination Figure 5 , Figure 6 , Figure 10 to Figure 12 as well as Fig.17In order to detect whether the food packaging box 800 is accommodated in the upper material bin 11, the loading device provided in this embodiment is provided with a food box detection switch 117, and the food box detection switch 117 is provided with a switch contact 1170. When the food packaging box 800 is accommodated in the upper material bin 11, the food packaging box 800 presses the switch contact 1170 of the food box detection module 3, and when the food packaging box 800 leaves the upper material bin 11, the food packaging box 800 releases the switch contact 1170, so that it can effectively detect whether the food packaging box 800 is accommodated in the upper material bin 11, so as to avoid starting subsequent actions such as unloading when the food packaging box 800 is not placed in the upper material bin 11. Specifically, a detection switch receiving box 1171 is provided at the outer wall position of the rear side wall 116 of the upper material bin 11 close to the bottom end surface 111 (i.e., the connection surface between the upper material bin 11 and the supporting frame 12), and the detection switch receiving box 1171 is integrally injection molded with the upper material bin 11. The food box detection switch 1117 is accommodated in the detection switch receiving box 1171, and the rear side wall 116 of the upper material bin 11 is provided with a through hole at a position corresponding to the detection switch receiving box 1171, and the switch contact 1170 of the food box detection switch 117 passes through the through hole to extend into the receiving space 110 of the upper material bin 11. When the food packaging box 800 is completely introduced into the loading bin 11 , the rear side wall of the food packaging box 800 presses against and presses the switch contact 1170 ; when the food packaging box 800 leaves the loading bin 11 , the rear side wall of the food packaging box 800 leaves to release the switch contact 1170 .

[0109] Therefore, by setting the food box detection switch 117 on the rear side wall 116 of the loading bin 11, when the food packaging box 800 is accommodated in the loading bin 11, the rear side wall of the food packaging box 800 presses against and presses the switch contact 1170 of the food box detection switch 117, and when the food packaging box 800 leaves the loading bin 11, the rear side wall of the food packaging box 800 leaves and releases the switch contact 1170, thereby effectively detecting whether the food packaging box 800 is accommodated in the loading bin 11, so as to avoid initiating subsequent actions such as unloading when the food packaging box 800 is not placed in the loading bin 11.

[0110] In addition, the bottom end surface 111 of the upper material bin 11 and the top surface 12139 of the outer frame of the supporting skeleton 12 are respectively provided with openings corresponding to the position of the detection switch receiving box 1171, and the electrical wires of the food box detection switch 117 received in the detection switch receiving box 1171 pass through the openings of the bottom end surface 111 and the top surface 12139 of the outer frame in turn to enter the receiving groove 12138 of the supporting skeleton 12, and pass through the driving shaft 140 after being routed through the receiving groove 12138 to achieve electrical connection with the controller, thereby sending the pressing and releasing states of the switch contact 1170 to the controller. In addition, when it is detected that the switch contact 1170 is pressed, the user can be prompted by icons, lights or sounds to indicate that the food packaging box 800 has been loaded into the upper material bin 11.

[0111] It can be seen that the feeding device 10 provided in this embodiment is provided with a food box detection switch 117 to effectively detect the introduction status of the food packaging box 800, and the food box detection switch 117 and the switch contact 1170 are provided on the rear side wall 116 of the feeding bin 11 close to the bottom end surface 111. Firstly, it is to be able to adapt to the effective detection of food packaging boxes 800 of different height capacities (to ensure that the food packaging box 800 with the smallest bin height can also press against the switch contact 1170), and secondly, it is to facilitate the routing of the food box detection switch 117, so that the electrical wire of the food box detection switch 117 is electrically connected to the controller outside the feeding device through the routing groove of the supporting frame 12.

[0112] Combination Figure 5 , Figure 6 , Figure 10 to Figure 12 as well as Fig.17 As shown, in order to transmit the information of the food materials, an electronic tag 810 is provided on the outer wall of the food material packaging box 800 in this embodiment, and the loading bin 11 is provided with a read-write module 118 matching the electronic tag 810, and the electronic tag 810 is arranged opposite to the read-write module 118. The electronic tag 810 may be a QR code, an IC card or an RFID tag, etc., and the read-write module 118 may be a reader / writer corresponding to the electronic tag 810. By arranging the electronic tag 810 on the outer wall of the food material packaging box 800, and arranging the electronic tag 810 opposite to the read-write module 118, so that the read-write module 118 can read or write information to the electronic tag 810, the information of the food materials, such as the code, recipe, production date or processing information, is transmitted to the control system of the cooking device, such as a cooking machine.

[0113] As a preferred design, the electronic tag 810 is arranged on the outer surface of the rear side wall of the food packaging box 800, and the electronic tag 810 is close to the top surface of the food packaging box 800. Correspondingly, a reader-writer receiving box 1181 is correspondingly arranged at the outer wall position of the rear side wall 116 of the upper material bin 11 close to the bottom end surface 111, and the reader-writer receiving box 1181 is integrally injection molded with the upper material bin 11. The reader-writer module 118 is accommodated in the reader-writer receiving box 1181. When the food packaging box 800 is introduced into the upper material bin 11, the electronic tag 810 on the outer surface of the rear side wall of the food packaging box 800 is close to the reader-writer receiving box 1181, and information can be read or written by the reader-writer module 118 of the reader-writer receiving box 1181. In this embodiment, the electronic tag 810 is preferably an RFID tag, and the reader-writer module 118 corresponds to an RFID reader-writer.

[0114] In addition, the bottom end surface 111 of the loading bin 11 and the top surface 12139 of the outer frame of the supporting skeleton 12 are respectively provided with openings corresponding to the position of the reader / writer receiving box 1181, and the electrical wires of the read / write module 118 received in the reader / writer receiving box 1181 pass through the openings of the bottom end surface 111 and the top surface 12139 of the outer frame in turn to enter the receiving groove 12138 of the supporting skeleton 12, and after being routed through the receiving groove 12138, pass through the driving shaft 140 to achieve electrical connection with the controller, thereby sending the read information to the controller or writing the control information of the controller into the electronic tag.

[0115] It can be seen that the loading device 10 provided in this embodiment can facilitate the routing of the reading and writing module 118 by arranging the reading and writing module 118 on the rear side wall 116 of the loading bin 11 close to the bottom end surface 111, so that the electrical wires of the reading and writing module 118 can be electrically connected to the controller outside the loading device through the wiring groove of the supporting frame 12.

[0116] Combination Fig.13a and Fig.13bAs shown, in order to facilitate the correct placement of the food packaging box 800, an indicator mark 824 for indicating the direction in which the food packaging box 800 is placed is provided on the top surface of the food packaging box 800 in this embodiment. Preferably, the indicator mark 824 is recessed; the indicator mark 824 is a direction arrow (the direction of indication is from the front side wall of the food packaging box 800 to the rear side wall). By providing the indicator mark 824, it is convenient to correctly place the food packaging box 800. In addition, in order to facilitate the smooth pushing of the food packaging box 800 into the upper bin 11, the indicator mark 824 is recessed to ensure that the indicator mark 824 does not protrude from the top surface of the food packaging box 800, thereby avoiding the food packaging box 800 from being stuck when being pushed into the upper bin 11.

[0117] Return to reference Figure 5 and Fig.10 In order to facilitate the cleaning of the feeding device 10, a flushing port 1120 penetrating the top surface 112 is provided on the top of the feeding bin 11 in this embodiment. When the feeding device 10 provided in this embodiment is installed in the sealed cooking cavity of the above-mentioned intelligent cooking machine, the nozzle of the flushing device arranged above the feeding device 10 can flush the entire interior of the feeding device 10 through the flushing port 1120, and the flushed water flows out through the discharge port 1210 of the feeding device 10 (the bin door plate 161 is opened by the bin door control mechanism 16). In addition, as a preferred design, a plurality of reinforcing ribs are provided on the outer surface of the feeding bin 11.

[0118] Return to reference Figures 4 to 6The feeding device 10 provided in this embodiment includes the lower hopper 13, which is a prism-shaped shell structure, and the lower hopper 13 is integrally injection molded. One end face of the lower hopper 13 used for connecting with the supporting frame 12 is the top end face 131 (top) of the lower hopper 13, and the other end face of the lower hopper 13 away from the top end face 131 is the bottom end face 132 (bottom) of the lower hopper 13. The lower hopper 13 is mainly composed of a bottom wall and four side walls connected to the bottom wall, and the top of the lower hopper 13 opposite to the bottom wall is an open structure. The top opening of the lower hopper 13 is connected to the lower feeding port 1210 on the supporting frame 12, which is conducive to the food falling through the lower feeding port 1210 entering the lower hopper 13. A total discharge port 130 is provided at the center of the bottom end surface 132 of the lower hopper 13. The bottom end surface 132 of the lower hopper 13 is inclined downward toward the total discharge port 130 along the connection with the four side walls of the lower hopper 13 and gradually shrinks, so that the lower hopper 13 is in a prism shape as a whole. The food material falling into the lower hopper 13 through the discharge port 1210, under the inclined guidance of the bottom end surface 132 of the lower hopper 13, finally falls through the total discharge port 130 to complete the discharge work. It can be understood that when the feeding device 10 provided in this embodiment is installed in the sealed cooking cavity of the above-mentioned intelligent cooking machine, after the food packaging box 800 is introduced through the feeding device, when the entire feeding device is turned over by the feeding device turning mechanism 14, the total discharge port 130 of the lower hopper 13 is directly opposite to the wok pot mouth below the feeding device 10.

[0119] In addition, the lower hopper 13 provided in this embodiment is connected to the bottom end surface 1212 of the supporting frame 12 and is used to close and seal the receiving groove 12138 provided on the bottom end surface 1212 of the supporting frame 12, so that the door switch and electrical wires of the door control mechanism accommodated in the receiving groove 12138 can be in the sealed space formed by the lower hopper 13 and the supporting frame 12, thereby achieving a sealing effect. Specifically, the top end surface 131 of the lower hopper 13 is matched with the bottom end surface 1212 of the supporting frame 12 of the supporting frame body 121 to achieve connection and sealing of the receiving groove 12138. In particular, the middle positions of the left and right sides of the top surface 131 of the lower hopper 13 correspond to the left lug 12130d and the right lug 12130b of the supporting frame 12, respectively, and extend outward to form a left lug covering portion 138 and a right lug covering portion 139. When the lower hopper 13 is connected to the supporting frame 12, the left lug covering portion 138 and the right lug covering portion 139 are used to close and seal the receiving grooves of the left lug 12130d and the right lug 12130b, respectively. It can be understood that the left lug covering portion 138 and the right lug covering portion 139 are integrally injection molded with the lower hopper 13. As a preferred design, a plurality of reinforcing ribs are provided on the outer surface of the lower hopper 13. In addition, a plurality of assembly positions are correspondingly distributed on the top end surface 131 of the lower hopper 13 and the bottom end surface 1212 of the supporting frame body 121, and the lower hopper 13 is connected and fixed to the supporting frame 12 by connecting parts such as screws at the assembly positions.

[0120] It can be seen that the feeding device 10 provided in this embodiment is provided with a lower hopper 13, so that the food in the food packaging box 800 introduced into the upper feeding bin 11 falls through the lowering opening 1210 when performing the feeding operation, and can be guided by the lower hopper 13 and fall into the corresponding cooking device through the main lowering opening 130 of the lower hopper 13. In addition, the lower hopper 13 is provided to be connected with the supporting frame, and the receiving groove 12138 provided on the bottom end surface 1212 of the supporting frame 12 is closed and sealed, so that the door switch and electrical wire of the door control mechanism accommodated in the receiving groove 12138 can be in the sealed space formed by the lower hopper 13 and the supporting frame 12, so as to achieve a sealing effect.

[0121] It can be understood that the above-mentioned lower hopper 13 is not a necessary component for the loading device 10 provided in this embodiment to achieve the technical effect of the technical invention. When the loading device 10 provided in this embodiment does not include the lower hopper 13, the supporting frame 12 may also include a supporting frame cover plate (not shown) for connecting and covering the receiving groove 12138 on the supporting frame main body 121.

[0122] In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", "top", "bottom", "front", "back" and the like indicate the orientation or position relationship based on the position of the loading device when it is in the unloading state ( Figure 3a The orientation or positional relationship between the various components (in the state shown) is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information.

[0123] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
