[0006] In the process of implementing the present invention, the inventors found that the existing door control mechanism and feeding device have at least the following problems: each door plate is provided with a door shaft to be installed on the feeding device. When there are multiple door plates, for example, four door plates are provided corresponding to four feeding ports, each door plate is connected to a door shaft, that is, a total of four door shafts need to be provided, and then the four door shafts are respectively installed on the feeding device, which is very troublesome to install and has low assembly efficiency, and also limits the expansion requirements of different specifications and quantities of compartment combinations, and cannot meet the requirements of different dishes.

[0028] As an improvement on the above scheme, the warehouse door shaft includes a first warehouse door shaft and a second warehouse door shaft. The left and right frames of the outer frame are provided with first warehouse door shaft through holes on the inner edges of the frame close to the front frame, and the rotating connection end of at least one of the warehouse door plates passes through the first warehouse door shaft through the first warehouse door shaft through the through hole to be fixed to the supporting frame body; the left and right frames of the outer frame are provided with second warehouse door shaft through holes on the inner edges of the frame close to the rear frame, and the rotating connection end of at least one of the warehouse door plates passes through the second warehouse door shaft through the second warehouse door shaft through the through hole to be fixed to the supporting frame body; the warehouse door switch is correspondingly arranged in the receiving groove of the horizontal arm.

The left and right frames of the outer frame are opposite to the horizontal arm and are provided with door shaft through-holes. The two door shafts are arranged in parallel and are respectively passed through the corresponding door shaft through-holes and then fixed to the horizontal arm. The door switches are correspondingly arranged in the receiving grooves of the front frame and the rear frame of the outer frame.

[0031] As an improvement on the above scheme, the wires used for each door switch to achieve electrical connection with the controller are routed through the receiving grooves and uniformly pass through openings provided on the receiving grooves to the outside of the supporting frame body to connect to the controller for independent control.

[0036] In the process of implementing the present invention, the inventors found that the existing warehouse door control mechanism still has the following problems: the existing warehouse door control mechanism usually uses a magnetically controlled latch structure to control the movement of the latch and the coordination between the warehouse door plate, thereby controlling the opening and closing of the warehouse door plate. This structure may easily cause jamming or difficulty in resetting during the opening and closing of the warehouse door plate due to reasons such as rust on the latch, thereby affecting the working stability of the warehouse door control mechanism and thus affecting the unloading operation. In addition, the use of a magnetically controlled latch structure has problems such as complex structure and very troublesome installation.

[0037] Therefore, the door control mechanism provided by the embodiment of the present invention further adopts an electromagnet to replace the push-pull electromagnet of the magnetically controlled latch structure of the prior art as the door switch, and controls the door plate to close or open the material discharge port to realize material discharge through the direct adsorption of the electromagnet on the door plate, which has a simple structure and is easy to install. In addition, it can effectively avoid the phenomenon of jamming or difficulty in resetting during the process of opening and closing the door plate due to rust of the latch in the existing magnetically controlled latch structure, thereby effectively improving the working stability and material discharge efficiency of the door control mechanism.

[0041] As an improvement on the above solution, the door plate is adsorbed by the electromagnet to close the discharge port when the electromagnet is energized, and the door plate falls by its own weight to open the corresponding discharge port when the electromagnet is de-energized and the adsorption force disappears.

[0042] As an improvement of the above solution, after the door plate opens the discharge port, the supporting frame body is flipped over so that the door plate falls down by its own weight to close the discharge port, and then the electromagnet is energized to adsorb the door plate.

[0044] As an improvement to the above solution, an opening is provided on the support frame cover corresponding to the electromagnet to protrude the electromagnet.

[0047] In addition, by using an electromagnet to replace the push-pull electromagnet of the prior art magnetically controlled latch-type structure as the door switch, the electromagnet directly adsorbs the door plate to control the door plate to close or open the material discharge port to achieve material discharge, which has a simple structure and is easy to install. It can also effectively avoid the phenomenon of jamming or difficulty in resetting during the process of opening and closing the door plate due to rust of the latch in the existing magnetically controlled latch-type structure, thereby effectively improving the working stability and material discharge efficiency of the loading device.

[0048] As an improvement of the above-mentioned solution, the supporting frame body is integrally injection-molded, and is also provided with connecting parts for directly connecting and fixing with the loading bin and the loading device flipping mechanism for flipping the loading device upside down as a whole, respectively. The loading bin, the loading device flipping mechanism and the supporting frame are directly connected via the connecting parts on the supporting frame body.

[0049] In addition, in the process of implementing the present invention, the inventor found that the existing loading device still has the following problems: the installation structure of the door control mechanism, the drive device and the rotary encoder is complicated, the door control mechanism needs to be fixed on the material bin body, and then the material bin body is embedded in the fixed frame, and the material bin body is respectively connected to the rotary encoder and the drive device through the fixed frame sleeved on the outside thereof, specifically, the first rotating shaft connected to the drive device and the second rotating shaft connected to the rotary encoder are respectively connected to the fixed frame after passing through the independently arranged bearing seat, and the connection structure is complicated and difficult to assemble, resulting in poor stability of the assembled loading mechanism. Therefore, the loading device provided by the embodiment of the present invention includes a supporting frame, through which an integral injection-molded loading port and a supporting frame body are provided, respectively, which are used to directly connect and fix with the loading bin, the door control mechanism and the loading device flipping mechanism. The loading bin, the door control mechanism and the loading device flipping mechanism can be directly connected to the supporting frame through the connecting part on the supporting frame body, so that the assembly of the loading device is easier, the structure is simple, and the assembled loading device is more stable.

[0050] As an improvement of the above solution, the top of the supporting skeleton body is a plane and serves as a connecting portion for directly and fixedly connecting the supporting skeleton body with the upper bin, and the bottom of the upper bin is matched with the top of the supporting skeleton body to achieve connection.

[0059] As an improvement of the above solution, the limit stopper is formed by the left and / or right side walls being recessed inwardly.

[0060] In the process of implementing the present invention, the inventor found that the existing loading device still has the following problems: after the unloading operation is completed (the door plate falls to fully open the unloading port), the loading device needs to be turned back 180 degrees by the loading device flipping mechanism to drive the door plate to reset, but when the door plate falls to fully open the unloading port, if the rotation angle is too large (for example, more than 90°), when the loading device is turned 180 degrees by the loading device flipping mechanism to reset the door plate, the door plate cannot move along the flipping and resetting direction under the action of its own gravity to achieve automatic reset. Therefore, the embodiment of the present invention provides a limit stopper on the inner wall of the unloading hopper of the loading device to limit the door plate of the door control mechanism from rotating around the door shaft to open the unloading port of the supporting skeleton body, so that the door plate rotates at an angle of no more than 90°, so that the door plate flips together with the loading device to achieve reset when the loading device is flipped, thereby solving the technical problem that the existing door plate is difficult to automatically reset due to the large rotation angle.

[0061] As an improvement of the above solution, the top end surface of the lower hopper is arranged to correspond to the bottom end surface of the supporting frame to achieve connection and closed sealing of the electrical wiring groove arranged on the bottom end surface of the supporting frame.

A control panel 1011 is also provided on the upper side of the housing 100, and the control panel 1011 is electrically connected to the controller; the control panel 1011 is provided with a plurality of function buttons or function touch areas so that the user can select different recipe instructions or cleaning instructions through the control panel 1011, thereby sending the corresponding recipe instructions or cleaning instructions to the controller.

[0102] In this embodiment, the feeding device 10 is disposed at the upper portion of the cooking cavity 101 , and the wok device 103 is disposed at the middle portion of the cooking cavity 101 and is located directly below the feeding device 10 .

[0103] The feeding device 10 includes a feeding bin 11 for accommodating food packaging boxes, a bin door control mechanism (not shown), a feeding hopper 13, a feeding device flipping mechanism 14 for flipping the feeding device 10 up and down as a whole, and a position detection device for detecting the position (angle) of the feeding device 10 flipping up and down as a whole (wherein the feeding device flipping mechanism 14 and the position detection device are preferably arranged between the outer shell and the inner shell). The bottom end surface of the feeding bin is provided with at least one feeding port that is aligned with the pot mouth of the wok body when feeding, and each of the feeding ports is provided with a bin door. The bin door control mechanism also includes a bin door switch for correspondingly driving the bin door to open and close. A feeding port for the food packaging box 800 for accommodating food is provided on one side of the feeding bin 11, and a vegetable box introduction port is provided on the side of the inner shell forming the cooking cavity, and the vegetable box introduction port is arranged correspondingly to the feeding port. The outer side of the vegetable box introduction port is the door panel 110 that can be opened and closed. The feeding device flipping mechanism is used for: when the food packaging box 800 is introduced through the feeding device, each of the feeding ports faces the opposite direction of the wok pot mouth, and the feeding port is aligned with the food box introduction port; after the food packaging box 800 is introduced through the feeding device, the feeding device is flipped through the feeding device flipping mechanism, so that each of the feeding ports faces the wok pot mouth, and then the door driving mechanism drives the door to open to achieve feeding. The feeding hopper 13 is used to guide the food falling through the feeding ports into the pot body.

[0104] The wok device 103 includes a pot body 1031, a furnace body (furnace core) 1032 for carrying the pot body 1031, a pot body turning device 1033 for fixing the furnace body (furnace core) 1032 inside the cooking cavity 101 and capable of driving the furnace body (furnace core) 1032 to turn the pot body 1031, a pot body heating device 1034 provided on the furnace body (furnace core) 1032 for heating the pot body 1031, and a pot body rotating device 1035 connected to the furnace body (furnace core) 1032 and used to drive the pot body 1031 to rotate relative to the furnace body (furnace core) 1032 around the longitudinal center axis of the pot body 1031. The pot body turning device 1033, the pot body heating device 1034 and the pot body rotating device 1035 are all connected to the controller for communication. The pot body flipping device 1033 drives the furnace body (furnace core) 1032 to flip the pot body 1031 to different positions to perform different position operations. The pot mouth of the pot body 1031 faces different directions (or devices) at different positions to perform corresponding operations in real time. Among them, the frying pan device 103 is also provided with a position detector that can be communicated with the controller on the connecting shaft between the furnace body (furnace core) 1032 and the pot body flipping device 1033, which is used to detect the flipping angle (position) of the furnace body (furnace core) 1032 and send it to the controller.

[0105] It is worth pointing out that the wok device 103 described in this embodiment can refer to the structure of the prior art (for example, patent publication number: CN103110339A, named "Wok device suitable for fully automatic cooking machine"; or patent publication number: CN107736790A, named "A wok device suitable for fully automatic cooking machine", etc.), and its structure is not specifically limited or described in detail here.

[0106] In this embodiment, the spray device 105 includes a spray pipe 1051, a spray nozzle 1052 connected to the spray pipe 1051, and a spray switch 1053 arranged on the spray pipe 1051. The spray nozzle 1052 is arranged on the top of the cooking cavity 101. Preferably, the top of the shell 100 is provided with an upper cover plate 120 that can be opened and closed, and the spray nozzle 1052 is preferably arranged on the upper cover plate 120. 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.

[0107] 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.

[0108] Among them, Figure 2 , Figure 3a and Figure 3bAs 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.

[0109] 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 by 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 by 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.

[0110] Below, the specific structure of an improved feeding device 10 proposed by 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.

[0111] 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.

[0112] Combination Figure 4 As shown in Figure 9, the supporting skeleton 12 provided in this embodiment includes an integrally injection-molded supporting skeleton main body 121, 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 connects the top end face 1211 and the bottom end face 1212 of the supporting skeleton main body 121, wherein 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 discharge 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.

[0113] 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.

[0114] 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.

[0115] In another embodiment, Figure 6 and 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.

[0116] In another embodiment, due to the use of an improved door control mechanism 16 (described in detail later) that can expand door (panel) combinations of different specifications and quantities, in order to match the food packaging box 800 that can import compartments of different specifications and quantities, the feed port 1210 provided in the center of the supporting skeleton body 121 can be correspondingly set to five (reference figure) or six (reference figure) or more.

[0117] Below Figure 6 and Figure 7Taking the supporting skeleton body of the food packaging box matching the four compartments as an example, the structure of the supporting skeleton theme 121 is further described. The supporting skeleton body 121 includes an outer frame 1213 and a central arm 1214, and the central arm 1214 is arranged at the center of the supporting skeleton body 121 and connected to the outer frame 1213 to form a feeding port 1210. Specifically, the outer frame 1213 is mainly composed of four frames, namely, a front frame 1213a, a right frame 1213b, a rear frame 1213c and a left frame 1213d, which are connected end to end in sequence, wherein the front frame 1213a is opposite to the rear frame 1213c, and the right frame 1213b is opposite to the left frame 1213d. 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 form 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. The receiving groove 12138 is also used to accommodate a door switch of a fixed door control mechanism (described in detail later).

[0118] 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.

[0119] The following is a description of the door control mechanism 16 provided in the embodiment of the present invention. It should be noted that the door control mechanism 16 provided in the embodiment of the present invention is a brand-new improved mechanism proposed by the inventor, and the improved door control mechanism 16 can effectively solve the technical problems existing in the door control mechanism and the corresponding feeding device of the prior art. 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 of the feeding device 10 through the door shaft 162, and each door plate 161 is used to close or open a feed opening 1210 of the supporting skeleton body 121 (each feed opening 1210 corresponds to a compartment of the food packaging box 800). The door switch 163 provided in this embodiment is an electromagnet, which is different from the push-pull electromagnet of the magnetically controlled latch structure used in the door switch of the prior art. The electromagnet used in this embodiment is a suction cup electromagnet, which does not need to include a push-pull iron core to act on the door plate. The electromagnet can directly absorb the door plate to control the closing or opening of the door plate. The electromagnet 163 is arranged on the supporting frame body and controls the closing or opening of the discharge port 1210 by adsorbing the door plate 161. 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 discharge port 1210 to realize the discharge operation.

[0120] In a preferred embodiment, the door plate 161 is made of a material that can be adsorbed by the electromagnet 163 . For example, the door plate 161 is made of a magnetic material that can be adsorbed by the electromagnet 163 . Therefore, the discharge port can be closed or opened under the adsorption of the electromagnet 163 .

[0121] In another preferred embodiment, the door plate 161 itself is not made of a material that can be adsorbed by the electromagnet 163, but an adsorption layer (not shown) made of a material that can be adsorbed by the electromagnet is provided on the door plate 161. Preferably, the adsorption layer is provided at a position where the door plate 161 is in contact with the electromagnet 163 when the door plate 161 is adsorbed by the electromagnet, thereby improving the adsorption force of the electromagnet 163 on the door plate 161, thereby improving the adsorption effect and efficiency.

[0122] It can be seen that the improved warehouse door control mechanism 16 provided in this embodiment adopts a suction cup electromagnet 163 to replace the push-pull electromagnet of the magnetically controlled latch structure in the prior art as a warehouse door switch, and controls the warehouse door plate 161 to close or open the material discharge port 1210 to realize material discharge through the direct adsorption of the warehouse door plate 161 by the suction cup electromagnet 163, so that the warehouse door plate 161 is adsorbed by the electromagnet 163 to close the material discharge port 1210 when the electromagnet 163 is energized, and the warehouse door plate 161 falls by its own weight to open the material discharge port 1210 when the electromagnet 163 is powered off and the adsorption force disappears, which can effectively avoid the phenomenon of jamming or difficulty in resetting during the process of opening and closing the warehouse door plate due to rusting of the latch and other reasons using the existing magnetically controlled latch structure, thereby effectively improving the working stability and material discharge efficiency of the warehouse door control mechanism. In addition, 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 allow the door plate 161 to fall back to its original position by its own weight to close the discharge port 1210, and then the electromagnet 163 is energized to adsorb the door plate 161 again.

[0123] It is understandable that when the compartment of the food packaging box 800 introduced is one compartment, when the feed opening 1210 provided at the center of the supporting skeleton body 121 is correspondingly set to one, and the compartment door plate 161 and the compartment door rotating shaft 162 of the compartment door control mechanism 16 are also corresponding to one, and the electromagnet 163 can be set to one or more to act on the compartment door plate 161. It is understandable that using multiple electromagnets 163 to act on the same compartment door plate 161 can effectively improve the adsorption force of the electromagnet 163 on the same compartment door plate 161, thereby ensuring the adsorption effect, especially when the compartment door plate 161 is designed to be larger.

[0124] Similarly, when the imported food packaging box 800 has multiple compartments, when the discharge port 1210 provided in the center of the supporting skeleton body 121 is correspondingly set to multiple, the number of the door plates 161 of the door control mechanism 16 is consistent with the number of the discharge ports 1210 and is matched, and each door plate 161 can be set to be adsorbed by at least one electromagnet 163.

[0125] In addition, during the implementation of the present invention, the inventors found that the existing door control mechanism and feeding device still have the following problems: each door plate is provided with a door shaft to be installed on the feeding device. When there are multiple door plates, for example, four door plates are provided corresponding to four feeding ports, each door plate is connected to a door shaft, that is, a total of four door shafts need to be provided, and then the four door shafts are respectively installed on the feeding device, which is very troublesome to install and has low assembly efficiency.

[0126] Therefore, in order to solve this problem, in view of the fact that there is more than one discharge port 1210, the door control mechanism 16 provided in the embodiment of the present invention makes a design improvement on the connection between the door plate 161 and the door shaft 162. Specifically, at least two door plates 161 are rotatably installed on the same door shaft 162, and are installed on the supporting frame body 121 through the same door shaft 162.

[0127] In one embodiment, the door shaft 162 includes one, and at least two door plates pass through the same door shaft 161, the door shaft 161 is connected to one side of the supporting frame body 121 (corresponding to the front frame 1213a / rear frame 1213c of the supporting frame body 121), and the electromagnet 163 is arranged on the other side of the supporting frame body 121 opposite to the one side (corresponding to the rear frame 1213c / front frame 1213a of the supporting frame body 121).

[0128] In another embodiment, Figure 8a to Figure 8c The door shaft 162 shown includes two, at least one door plate 161 passes through one door shaft and is connected to one side of the supporting frame body 121 (corresponding to the front frame 1213a / rear frame 1213c of the supporting frame body 121), at least one door plate 161 passes through another door shaft 162 and is connected to the other side of the supporting frame body 121 opposite to the one side (corresponding to the rear frame 1213c / front frame 1213a of the supporting frame body 121), and the electromagnet 163 is arranged on the supporting frame body at a position between the one side and the other side (preferably a middle position, corresponding to the transverse arm 1214a of the supporting frame body 121, and the transverse arm 1214a may be provided with a receiving groove for accommodating and fixing the electromagnet 163).

[0129] in, Figure 8a to Figure 8bShown is the corresponding structure of the door control mechanism 16 of the loading device suitable for importing four-compartment food packaging boxes, wherein the supporting skeleton body 121 is provided with a first discharge port 1210a, a second discharge port 1210b, a third discharge port 1210c and a fourth discharge port 1210d, and the door control mechanism 16 is correspondingly provided with a first door plate 161a, a second door plate 161b, a third door plate 161c and a fourth door plate 161d, and the door shaft 162 includes two, namely a first door shaft 162a and a second door shaft 162b, wherein the first door plate 161a and the second door plate 161b are both rotatably mounted on the first door shaft 162a, and the third door plate 161c and the fourth door plate 161d are both rotatably mounted on the second door shaft 162b.

Wherein, a receiving groove for receiving and fixing the electromagnet 163 can be provided on the transverse arm 1214a of the supporting skeleton body 121, and a corresponding electromagnet installation position 1630 is provided on the receiving groove to correspondingly install the electromagnet 163. Wherein, the second door panel 161b and the third door panel 161c are larger than the first door panel 161a and the fourth door panel 161d, and the movable ends of the second door panel 161b and the third door panel 161c are arranged to be adsorbed by two electromagnets 163 respectively to improve the adsorption force.

[0130] in, Figure 8c The corresponding structure of the door control mechanism 16 shown is Figure 8a to Figure 8b The door control mechanism 16 shown is basically the same, except that: Figure 8c The displayed door control mechanism 16 expands more door combinations of different specifications and quantities. For example, the supporting frame body 121 is provided with a first material discharge port 1210a, a second material discharge port 1210b, a third material discharge port 1210c, a fourth material discharge port 1210d, a fifth material discharge port 1210e and a sixth material discharge port 1210f, a total of six material discharge ports, and the door control mechanism 16 is correspondingly provided with six door plates, three of which are rotatably connected to the first door shaft 162a, and the other three door plates are rotatably connected to the second door shaft 162b.

[0131] In yet another embodiment, Figure 8d As shown, the door shaft 162 includes two shafts, at least one door plate 161 passes through one door shaft 162, and at least one door plate 161 passes through the other door shaft 162. The electromagnets 163 are respectively arranged on the opposite sides of the supporting frame body 121 (corresponding to the front frame 1213a and the rear frame 1213c of the supporting frame body 121, and the front frame 1213a and the rear frame 1213c are provided with electromagnet installation positions in the receiving grooves), and the two door shafts 162 are connected in parallel to the position between the opposite sides of the supporting frame body 121 (preferably the middle position, corresponding to the horizontal arm 1214a of the supporting frame body 121). Specifically, the door shaft 162 includes a first door shaft 162a and a second door shaft 162b. The right frame 1213b and the left frame 1213d are respectively provided with two door shaft through holes at the positions opposite to the horizontal arm 1214a. The first door shaft 162a and the second door shaft 162b are arranged in parallel and are respectively passed through the corresponding door shaft through holes and then fixed on the horizontal arm 1214a. The electromagnet 163 is correspondingly arranged in the receiving grooves of the front frame 1213a and the rear frame 1213c of the supporting skeleton body 121.

[0132] In yet another embodiment, which is also the most preferred embodiment of the door control mechanism 16 provided by the present invention, as Figure 6 , Figure 7 and Figure 8eAs shown, the electromagnets 163 are respectively arranged on the opposite sides of the supporting frame body 121 (corresponding to the front frame 1213a and the rear frame 1213c of the supporting frame body 121, and the front frame 1213a and the rear frame 1213c are provided with electromagnet installation positions in the receiving grooves), and the warehouse door shaft 162 includes one and is connected to a position between the opposite sides of the supporting frame body 121 (preferably a middle position, corresponding to the horizontal arm 1214a of the supporting frame body 121), and all two warehouse door plates 161 pass through the same warehouse door shaft 162 and are arranged on both sides of the warehouse door shaft 162, so as to be respectively adsorbed by the electromagnets 163 arranged in the front frame 1213a and the rear frame 1213c. Among them, one end of each of the door plates 161 is staggered and passed through the same door shaft 162 by setting a door plate shaft sleeve 1611, and the other end of each of the door plates 161 is a movable end 1612 that can rotate around the door shaft 162, and the electromagnet 163 arranged in the front frame 1213a and the rear frame 1213c acts on the movable end 1612 accordingly.

[0133] in, Figure 6 and Figure 7The structure shown is a corresponding structure of a door control mechanism 16 of a loading device suitable for introducing a four-compartment food packaging box, wherein the supporting skeleton body 121 is provided with a first discharge port 1210a, a second discharge port 1210b, a third discharge port 1210c and a fourth discharge port 1210d, and the door control mechanism 16 is correspondingly provided with a first door plate 161a, a second door plate 161b, a third door plate 161c and a fourth door plate 161d, and the right frame 1213b and the left frame 1213d are respectively provided with door shaft through-holes at positions opposite to the transverse arm 1214a, and one end of the first door plate 161a, the second door plate 161b, the third door plate 161c and the fourth door plate 161d are provided with door plate shaft sleeves 1611 to pass through the same door shaft 162 in an offset manner, and both ends of the door shaft 162 are fixed to the transverse arm 1214a after passing through the corresponding door shaft through-holes. The other ends of the first door plate 161a, the second door plate 161b, the third door plate 161c and the fourth door plate 161d are movable ends 1612 that can rotate around the door shaft 162. As an illustrative example of "staggered penetration" to connect all the door plates to the same door shaft, for example, the first door plate 161a is provided with a door plate shaft sleeve 1611a and a door plate shaft sleeve 1611a', the second door plate 161b is provided with a door plate shaft sleeve 1611b and a door plate shaft sleeve 1611b', the third door plate 161c is provided with a door plate shaft sleeve 1611c and a door plate shaft sleeve 1611c', and the fourth door plate 161d is provided with a door plate shaft sleeve 1611c and a door plate shaft sleeve 1611c', and the The door plate 161d is provided with a door plate shaft sleeve 1611d and a door plate shaft sleeve 1611d', and one end of the door shaft 162 passes through the door plate shaft sleeve 1611a, the door plate shaft sleeve 1611c, the door plate shaft sleeve 1611a', the door plate shaft sleeve 1611b, the door plate shaft sleeve 1611c', the door plate shaft sleeve 1611d, the door plate shaft sleeve 1611b' and the door plate shaft sleeve 1611d' in sequence to connect all the door plates. It can be understood that each door plate 161 can also be connected to the same door shaft 162 by other staggered passing methods, and is not limited to Figure 7 The scheme shown.

[0134] Figure 8e The corresponding structure of the door control mechanism 16 shown is Figure 7 The door control mechanism 16 shown is basically the same, except that: Figure 8eThe displayed door control mechanism 16 expands more door combinations of different specifications and quantities. For example, the door control mechanism 16 is correspondingly provided with five door plates, namely, the first door plate 161a, the second door plate 161b, the third door plate 161c, the fourth door plate 161d and the fifth door plate 161e, wherein one end of the first door plate 161a, the second door plate 161b, the third door plate 161c, the fourth door plate 161d and the fifth door plate 161e are provided with a door plate shaft sleeve 1611 to pass through the same door shaft 162 in an offset manner, and the other ends of the first door plate 161a, the second door plate 161b, the third door plate 161c, the fourth door plate 161d and the fifth door plate 161e are movable ends 1612 that can rotate around the door shaft 162.

[0135] It can be seen that the improved structure of the warehouse door control mechanism 16 provided in the embodiment of the present invention, by setting at least two of the warehouse door plates to be rotatably installed on the same warehouse door shaft, and being installed on the supporting frame body through the same warehouse door shaft, can make the installation of the warehouse door control mechanism more convenient and effectively improve the assembly efficiency. In addition, whether the single-axis or double-axis warehouse door shaft design is adopted, the combination of compartments of different specifications and quantities can be realized to meet the needs of different dishes. In particular, the warehouse door plate shaft sleeves of multiple warehouse door plates are staggered to pass through the same warehouse door shaft and are arranged on both sides of the warehouse door shaft, and are connected to the position between the opposite sides of the supporting frame body (preferably the middle position) through the warehouse door shaft, which can further reduce material cost and improve assembly efficiency, and is more suitable for introducing most of the current food packaging boxes (the spacing between the compartments of the food packaging boxes is often small), so that there is no need to make additional designs for the food packaging boxes to meet the structural requirements of the warehouse door control mechanism and the feeding device.

[0136] It can be understood that in the door control mechanism 16 provided in this embodiment, by connecting each of the electromagnets to a controller, the controller controls each electromagnet 163 to work independently, thereby controlling the time and order of opening each door panel 161, and further controlling the time and order of placing 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 order of placing ingredients in different compartments in the food packaging box 800 according to the recipe instructions. In addition, Figure 6As shown, the wires used for each electromagnet 163 to achieve electrical connection with the controller are routed through the receiving grooves 12138 on the supporting skeleton body 121 and uniformly pass through the openings set in the receiving grooves 12138 (in this embodiment, it is preferred to pass through a shaft sleeve and a hollow shaft that are integrally injection molded with the supporting skeleton body 121) to the outside of the supporting skeleton body 121 to connect to the controller to achieve independent control.

[0137] 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.

[0138] 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.

[0139] 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.

[0140] 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.12 The 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 loading device 10, thereby effectively preventing part of the food from being spilled during the flipping process of the loading device 10 and ensuring the normal unloading 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.

[0141] As a preferred design, please continue to refer to Figure 6 , Fig.11 and Fig.12 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 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.

[0142] 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 grooves (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 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, 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 a 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 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).

[0143] 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 (one 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.

[0144] 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 .

[0145] 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.

[0146] 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.

[0147] 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 with 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.

[0148] 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, the outer wall of the food material packaging box 800 in this embodiment is provided with an electronic tag 810, 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. Among them, the electronic tag 810 can be a QR code, an IC card or an RFID tag, etc., and the read-write module 118 can 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.

[0149] 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.

[0150] 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. 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, they 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.

[0151] 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.

[0152] 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 setting 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.

[0153] 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.

[0154] 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 placed below the feeding device 10.

[0155] 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.

[0156] 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 members such as screws at the assembly positions. Figure 5 , the lower hopper 13 is connected to the left and right sides corresponding to the supporting frame 12 by screws, and the lower hopper 13 is connected to the front and rear sides corresponding to the supporting frame 12 by snaps. Specifically, the left and right sides corresponding to the lower hopper 13 and the supporting frame 12 are provided with screw locks 1000 for screw connection. The front and rear sides of the lower hopper 13 are provided with buckles 1300, and the front and rear sides of the supporting frame 12 are provided with snaps 1200 for snap connection with the buckles 1300. The front and rear sides corresponding to the lower hopper 13 and the supporting frame 12 are fixedly connected by the buckles 1300 and the snaps 1200, and the screws are fixed and locked from the screw locks on the left and right sides corresponding to the lower hopper 13 and the supporting frame 12, wherein the design of the buckles 1300 and the snaps 1200 between the front and rear sides corresponding to the lower hopper 13 and the supporting frame 12 can effectively reduce the occupied space.

[0157] In addition, during the implementation of the present invention, the inventors discovered that the existing feeding device still has the following problems: after the feeding operation is completed (the bin door plate falls to fully open the feeding port), the feeding device needs to be flipped back 180 degrees as a whole through the flipping mechanism of the feeding device to drive the bin door plate to reset. However, when the bin door plate falls to fully open the feeding port, if the rotation angle is too large (for example, more than 90°), when the feeding device is flipped 180 degrees by the flipping mechanism of the feeding device to reset the bin door plate, the bin door plate cannot move in the flipping and resetting direction under the action of its own gravity to achieve automatic reset.

[0158] To this end, the embodiment of the present invention improves the feeding device 10 to solve the technical problem that the existing door panel is difficult to automatically reset due to the large rotation angle. Figure 4 as well as Figures 9a to 9c As shown, in this embodiment, a limit block 1390 is provided on the inner wall of the lower hopper 13 of the loading device 10, and the limit block 1390 is used to limit the door plate 161 of the door control mechanism 16 from rotating around the door shaft 162 to open the lower feeding port of the supporting skeleton body 121, so that the rotation angle of the door plate 161 does not exceed 90°.

[0159] In a preferred embodiment, the limit stopper 1390 is used to limit the rotation angle of the door plate 161 around the door shaft 162 to open the discharge port within a range of 60° to 90°.

[0160] In another preferred embodiment, the limit stopper 1390 is used to limit the rotation angle of the door plate 161 around the door shaft 162 to open the discharge port within a range of 75° to 90°.

[0161] Furthermore, when the door shaft 162 is connected to the left and right sides of the supporting frame body 121 and is arranged at a position between the front and rear sides of the supporting frame body (preferably a middle position, corresponding to the transverse arm 1214a of the supporting frame body 121), the limit stop block 1390 is correspondingly arranged on the inner wall of at least one of the left and right side walls of the lower hopper 13 to face the door shaft 162.

[0162] Furthermore, there are two limit blocks 1390, which are respectively arranged on the inner walls of the left and right side walls of the lower hopper 13 to face the door rotating shaft 162. The longitudinal section of each limit block 1390 is an isosceles trapezoid. Figure 4 As shown, the limit stopper 1390 is integrally injection-molded with the lower hopper 13, and the limit stopper 1390 is formed by the left and right side walls being recessed inwardly.

[0163] refer to Figure 6, Figure 9a to Figure 9c Next, in combination with the working principle of the feeding device 10, the technical problem of how the limit stopper 1390 added in the lower hopper 13 of this embodiment can overcome the difficulty in automatic resetting caused by the excessive rotation angle of the door plate is further discussed.

[0164] After the feeding device 10 imports the food packaging box, when it receives the instruction to prepare for unloading, the controller energizes the door switch (electromagnet), and the door plate 161 is locked under the action of the corresponding door switch (for example, the suction of the electromagnet 163). The feeding device flipping mechanism flips the entire feeding device to the unloading state. At this time, under the action of the door switch (for example, the suction of the electromagnet), the door plate is still in a closed state. When it is necessary to open the unloading port for unloading, the electromagnet 163 is powered off, the suction of the electromagnet disappears, and the door plate falls by its own weight to realize the automatic opening of the door plate 161 (wherein, the first door plate 161a and the second door plate 161b rotate around the door shaft 162 during the falling process as shown in FIG. 1 ). Figure 9a As shown by arrow A1, the rotation direction of the third door plate 161c and the fourth door plate 161d during the falling process is as follows: Figure 9a As shown by arrow A2, when the door plate 161 is fully opened, due to the limiting effect of the limit stopper 1390, the door plate 161 is at the limit stopper 1390, as shown in FIG. Figure 9a As shown;

[0165] After unloading is completed, when receiving the reset instruction of the feeding device 10, the feeding device 10 is turned back as a whole by the turning mechanism of the feeding device (the turning direction is as follows: Figure 9b During the flipping process, the third door plate 161c and the fourth door plate 161d move in the opposite direction of the flipping direction of the feeding device 10 under the action of their own gravity (movement is lowered as shown in FIG. Figure 9b As shown by the arrow B2), the first door plate 161a and the second door plate 161b are flipped with the feeding device 10 under the action of the limit stopper 1390 (the direction of movement is as shown in FIG. Fig.9c As shown by the arrow B1, when the feeding device 10 is flipped to the reset state, the first door plate 161a and the second door plate 161b form an angle less than 90° with the supporting frame 12 of the feeding device 10, so they continue to move along the original flipping and resetting direction under the action of their own gravity, and finally achieve reset, as shown in Figure 9c.

[0166] 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.

[0167] Further, return to reference Figure 6 In order to provide waterproof and dustproof protection for the electromagnet 163 in the receiving groove 12380 of the supporting frame body 121, the supporting frame 12 provided in this embodiment further includes a supporting frame cover plate 122, which is connected to the supporting frame body 121 and is used to cover and seal the receiving groove on the supporting frame body 121. Accordingly, the supporting frame cover plate 122 is provided with an opening corresponding to each electromagnet 163 on the supporting frame body 121 to protrude the electromagnet 163.

[0168] Understandable, such as Figure 5 and Figure 6 As shown, when the supporting frame 12 of the feeding device 10 provided in this embodiment further includes a supporting frame cover plate 122, the supporting frame body 121 can be connected and fixed with the supporting frame cover plate 122, and then connected and fixed with the lower hopper 13 through the supporting frame cover plate 122. That is, the screw lock 1000 for screw connection and the bayonet 1200 for achieving bayonet connection with the buckle 1300 of the lower hopper 13 can be arranged on the supporting frame cover plate 122, and the implementation effect of the embodiment of the present invention can also be achieved.

[0169] Further, such as Figure 6 As shown, in this embodiment, in order to buffer the rigid collision between the door plate 161 and the supporting frame 12 and to reduce noise, a shock-absorbing pad 164 is provided on the supporting frame body 121 to buffer the rigid collision between the door plate 161 and the supporting frame body 121. Exemplarily, the shock-absorbing pad 164 is a soft rubber pad.
