DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] The specific embodiments of the present invention will be described in more detail below with reference to the drawings and examples. The following examples are provided to illustrate the present invention and are not intended to limit the scope of the present invention.

[0022] As shown in Figures 1 to 20, the supply mechanism 200 used in the fryer of the present invention can be easily removed and installed from the frame 100 of the fryer, making it convenient for users to clean and replace, and effectively improving the user experience.

[0023] The feeding mechanism 200 mainly comprises a base frame 1, a movable baffle 2, a case frame, a guide groove 5, a support assembly and an electromagnetic assembly 9.

[0024] 1. Base frame 1 and movable baffle 2 (upper, lower, left, right, front, rear directions are based on FIG. 1, and the same applies below)

[0025] As shown in Figs. 1 to 4, the base frame 1 is a load-bearing member of the supply mechanism, and includes an outer frame 11, a horizontal beam 12, and a vertical beam 13. In this embodiment, four supply ports 14 are formed between the three of them to correspond to the discharge ports of the food case 43. Above the supply ports 14, movable baffles 2 of equal area are provided correspondingly. Directly above the horizontal beams 12, a connection shaft 21 for hinge-connecting the movable baffles 2 is provided. Correspondingly, connection shaft holes 15 are formed in the outer frame 11 and the vertical beams 13. The connection shaft 21 passes through the hinge connection side 22 of each movable baffle 2 and the connection shaft hole 15 of the vertical beam 13, and both ends are provided in the connection shaft hole 15 of the outer frame 11. The movable side edge of the movable baffle 2 overlaps the narrow baffle 16 extending from the inside of the outer frame 11, thereby ensuring that the supply port 14 is always covered.

[0026] It is preferable that the movable baffle 2 is sprayed with a food-grade anti-stick paint, such as a common anti-stick paint such as Teflon, which can ensure that no food remains on the movable baffle 2 during the use of the stir-fry machine, and can be easily cleaned automatically by the machine or manually by the user.

[0027] As shown in FIG. 4, FIG. 6 to FIG. 9, the outer frame 11 has pin holes 17 formed on both sides. In order to facilitate production, in this embodiment, the pin holes 17 on both sides are formed symmetrically and have a symmetrical internal structure. The pin holes 17 accommodate the pins 3. The outer side of the pins 3 is provided with a return spring 33. The front end of the pins 3 is located above the loose-leaf side 23 of the movable baffle 2, and the edge of the loose-leaf side 23 is sandwiched between the pins and the narrow baffle 16. The pin holes 17 are step holes, which are a first step 171, a second step 172, and a third step 173 from left to right as shown in FIG. 8. The second step 172 has a smaller inner diameter than the first step 171 and the third step 173. The pins 3 are accommodated in the first step 171 and the second step 172. The front part of the pins 3 is provided with a limiting ring 31 disposed in the first step 171. The outer diameter of the limit ring 31 is larger than the inner diameter of the second step 172. A permanent magnet 32 ​​is fixed to the rear end of the pin 3, which is disposed in the third step 173. The fixing manner may be multiple, such as engagement, adhesion, rotational connection, etc. In order to simplify the structure and ensure the installation, the present embodiment uses the rotational connection manner for fixing.

[0028] The pin 3 can move back and forth in the step hole. The movable distance is the distance from the limiting ring 31 to the second step 172. When the pin 3 moves back, the front end face of the pin 3 is accommodated in the first step 171. At this time, the movable baffle 2 is not restricted by the pin 3, and its loose-leaf side 23 is free to rotate above the narrow baffle 16 along the connecting shaft 21.

[0029] 4, engaging buckles 18 are protruding from the left, right and rear sides of the upper surface of the outer frame 11, and an engaging member 19 is provided on the front end surface. The engaging buckles 18 and the engaging members 19 are both used to realize quick attachment and detachment to the guide groove 5, and are convenient for production assembly and post-maintenance cleaning or replacement by the user.

[0030] 2. Case frame

[0031] As shown in FIG. 1 and FIG. 4, the case frame is installed below the base frame 1 and is used to support the food case 43. The case frame is two guide rail frames 4 independently provided on the lower left and lower right sides of the base frame 1 facing each other. The internal structure of the two guide rail frames 4 is symmetrical. The upper end of the guide rail frame 4 is provided with a connection edge 41 that is in close contact with the lower surface of the outer frame 11. The connection edge 41 can be rotatably connected to the outer frame 11 by a nut stud method, or can be engaged by an engagement member (not shown) attached to the lower part of the outer frame 11 in an engagement method, and the description will be omitted here. As shown in FIG. 4, a broken line-shaped guide rail protrusion 42 is provided in the center of the guide rail frame 4. A user can push the food case 43 into the case frame along the guide rail protrusions 42 on both the left and right sides. The guide rail protrusions 42 can support the food case 43 so that the food case 43 is suspended and arranged in the frying machine.

[0032] The case frame has an open bottom. During the automatic cleaning process of the frying machine, the feeding mechanism 200 is in the feeding position, and the cleaning head (not shown) on the top of the frame 100 can directly spray the movable baffle 2 that contacts the food. When the user manually cleans, it is also convenient for the user to directly clean the movable baffle 2 and the guide rail frame 4.

[0033] 3. Guide groove 5

[0034] As shown in Figs. 1, 2 and 4, the guide groove 5 is provided above the base frame 1 and is used to guide the ingredients in the ingredient case 43 into the frying pan 400. In this embodiment, the guide groove 5 is preferably a funnel-shaped groove having a flow-guiding effect. An outer edge 51 is provided at the lower opening edge of the guide cover, which extends around the periphery. A protrusion 52 is provided at the upper periphery of the outer edge 51. The protrusion 52 of the outer edge 51 can be inserted into the engagement buckle 18 of the outer frame 11. The engagement member 19 and the front protrusion 52 of the outer edge 51 are engaged with each other, so that the guide groove 5 can be quickly engaged with the outer frame 11 so that the bottom surface of the guide groove 5 is in close contact with the upper surface of the outer frame 11.

[0035] The lower opening of the guide groove 5 has the same shape and size as the inner ring of the outer frame 11. The diameter of the upper end opening 54 of the guide groove 5 is equal to or smaller than the diameter of the pot opening 401, which can ensure that when the supply mechanism 200 rotates 180 degrees to the supply position (as shown in FIG. 2 ), after each movable baffle 2 is opened, all the ingredients on the bun frame in the ingredient case 43 will fall along the guide groove 5 into the pot.

[0036] 5, the inner wall of the guide groove 5 directly above both ends of the connecting shaft 21 is provided with a limiting block 53 protruding inward. When the supply mechanism 200 is in the supply position, the limiting block 53 can prevent the movable baffle 2 from being in a drooping state (i.e., facing vertically downward) when it is opened. This arrangement can not only prevent the loose-leaf sides 23 of the two opposing movable baffles 2 from colliding with each other, but also ensure that each movable baffle 2 rotates to its original position when the supply mechanism 200 is reversed, so that each movable baffle 2 automatically returns to its original position to accurately cover the corresponding supply port 14.

[0037] 4. Support Assembly

[0038] As shown in Figures 1 and 2, support assemblies are provided on both sides of the base frame 1, which are used to suspend and mount the supply mechanism 200 on the frame 100 of the fryer, and can realize quick attachment and detachment between the supply mechanism 200 and the frame 100. The support assemblies are composed of a driving release member and a driven release member. One side connected to the motor output shaft 301 is called the driving release member, and the other side is called the driven release member. As shown in Figure 3, the motor 300 is provided on the left side of the frame 100. The right side of the frame 100 is formed with a mounting hole 101 for mounting the driven release member.

[0039] The preferred support assemblies of the present invention are of two types:

[0040] (1) Slide block slide groove structure (the direction facing the base frame 1 is the front, the opposite direction is the rear, and so on)

[0041] As shown in FIG. 11 and FIG. 12, slide blocks are provided on both the left and right sides of the outer surface of the outer frame 11, the left side being a main slide block 601, and the right side being a slave slide block 602. Correspondingly, the frame 100 is provided with a main slide groove 61 and a slave slide groove 62 on both sides. The slide blocks can be inserted into the slide grooves. The main slide groove 61 is provided with a connection portion 611 and a slide groove portion 612. The connection portion 611 is engaged and fixed to the motor output shaft 301, and the slide groove portion 612 is used to support the main slide groove 61. The slave slide groove 62 is provided with an engagement portion 621 and a slide groove portion 612. The engagement portion 621 is engaged and fixed to the front end portion of the driven shaft 71, and the slide groove portion 612 is used to support the slave slide block 602. An engagement base 711 is protruded from the outer wall of the rear portion of the driven shaft 71. The driven shaft 71 is attached to the frame 100 via a fixing structure. The fixing structure includes a waterproof plate 73, an oil seal 74, a bearing 75, and a fixing member 76. The waterproof plate 73 and the oil seal 74 are disposed inside the mounting hole 101 of the frame 100. Here, the waterproof plate 73 is fixed to the mounting hole 101. The waterproof plate 73 has a central through hole formed therein. The central through hole is formed coaxially with the mounting hole 101. The oil seal is provided in the central through hole. The bearing 75 and the fixing member 76 are disposed outside the mounting hole 101. The front end of the driven shaft 71 passes through the mounting hole 101 and the oil seal 74 in this order from the outside of the frame 100 and is fixed to the engagement portion 621 of the slave slide groove 62. The front end surface of the engagement base 711 abuts against the oil seal 74, so that water in the frame 100 cannot pass through the oil seal 74 and flow out of the frame 100, thereby achieving a sealing effect. The fixing member 76 has a central through hole formed therein. The bearing 75 is embedded in the central through hole, and its outer ring tightly engages with a fixed member 76. The rear end of the driven shaft 71 passes through the inner ring of the bearing 75. The rear end surface of the engagement base 711 abuts against the inner ring. The fixed member 76 is fixed to a frame 100.

[0042] In order to ensure the stability of the connection between the slide block and the slide groove, a strong magnet 63 is embedded in the front end surface where the slide block and the slide groove come into contact. In the process of removing the supply mechanism 200 by the user, if the pulling force is greater than the attractive force of the strong magnet 63, it can be easily removed. In order to make it easier for the user to install the supply mechanism 200 on the frying machine, the inlet end of the slide groove is further provided with a chamfer, which makes it easier for the slide block to be pushed into the slide groove. The cross-sectional shape of the slide block is adapted to the cross-sectional shape of the slide groove, and may have a variety of shapes, such as a rectangle, a triangle, etc.

[0043] In order to ensure that the feeding mechanism 200 is mounted in a predetermined position before the stir frying machine, an induction switch can be provided between the slide groove and the slide block. A mechanical position switch or a non-contact induction switch can be selected. Since the mounting position is limited and requires good waterproof performance, it is preferable to use a magnetic reed switch in front of the main slide groove 61 and the main slide block 601. The reed switch 64 in the magnetic reed switch is fixed in the slave slide block 602. The wiring of the reed switch 64 passes through the slave slide block 602 and the driven shaft 71 and is electrically connected to the main control circuit of the stir frying machine, while the magnet 65 is embedded in the slave slide block 602.

[0044] As shown in Fig. 12, the main slide groove 61 is engaged with a motor output shaft 301 and fixed by a nut stud method. The slave slide groove 62 is fixed to a driven shaft 71 and is mounted on the frame 100 via the driven shaft 71. The motor output shaft 301 drives the main slide groove 61. By moving the main slide block 601 of the base frame 1 in a rotating manner, the main slide groove 61 rotates the supply mechanism 200 in a vertical plane, and the slave slide block 602, the slave slide groove 62 and the driven shaft 71 rotate following the rotation of the supply mechanism 200.

[0045] When installing supply mechanism 200, the user aligns the slide blocks on both sides with the slide grooves and pushes them to the bottom, so that the slide blocks are attracted to the strong magnets 63 on the front end faces of the slide grooves, completing installation. When removing supply mechanism 200, the user pulls out supply mechanism 200, releases the attraction between the slide blocks and the magnets on the front end faces of the slide grooves, and removes the slide blocks from the slide grooves, completing removal.

[0046] The slide block and slide groove structure makes it convenient to install and remove the supply mechanism 200, and users can operate the installation and removal with one hand, which effectively improves the user's experience of using the stir fry machine.

[0047] (2) Shaft and shaft sleeve structure

[0048] As shown in FIG. 1 and FIG. 13, shafts are provided on both the left and right sides of the outer surface of the base frame 1, the left side being the step shaft 81, and the right side being the support shaft 82. Correspondingly, a motor shaft 301 that engages with the step shaft 81 is provided on the left side of the frame 100. An axial engagement hole 302 is formed at the front end of the output shaft 301. The step shaft 81 is fixed at one end to the left side of the base frame 1, and the other end is an engagement block that fits the axial engagement hole 302. The axial engagement hole 302 can engage with the engagement block. There are multiple types of engagement methods, such as D-shaped engagement and polygonal engagement, but the description is omitted here. A shaft seat structure for supporting the end of the support shaft 82 is provided on the right side of the frame 100. The shaft seat structure is attached to the mounting hole 101. In order to ensure the installation stability and convenience of the supply mechanism 200, the step shaft 81 and the motor output shaft 301 are fixed in an engagement manner. The support shaft 82 can move axially in the shaft seat structure, and the shaft seat structure is provided with a limiting structure. The user first places the end of the support shaft 82 in the shaft seat, moves the supply mechanism 200 to the right, then aligns and engages the step shaft 81 and the output shaft 301, and finally, the step shaft 81 and the motor output shaft 301 are always kept in an engaged mesh state by automatic restriction by the limiting mechanism or manual restriction by the limiting mechanism (shown in FIG. 13 ).

[0049] 1) Automatic limiting axle seat structure

[0050] As shown in Figs. 13 and 14, the shaft seat structure is composed of a shaft sleeve 83, a limiting sleeve 84, a spring cap 85, a spring 86, and a spring seat 87, from front to rear. The rear end of the limiting sleeve 84 is inserted into the mounting hole 101 so as to be fixed to the frame 100. An axial sleeve hole 841 is formed in the front end surface of the limiting sleeve 84. The shaft sleeve 83 is embedded in the sleeve hole 841. The shaft sleeve 83 is used to connect the end of the support shaft 82. The support shaft 82 can rotate freely in the shaft sleeve 83. In order to reduce friction, in this embodiment, a plastic shaft sleeve 83 with lubricating properties is preferred. The limiting sleeve 84 is further formed with a cap hole 842 located behind the sleeve hole 841 and extending axially rearward. An engagement protrusion 843 is protruded from the front of the cap hole 842. The spring cap 85 is inserted into the cap hole 842 from rear to front, and the flange portion 852 can abut against the engagement protrusion 843. The spring seat 87 is located at the rear end of the limiting sleeve 84 so as to be fixed to the frame 100, and has an axial protrusion 871 on its inner bottom surface for preventing the spring 86 from deforming. The spring 86 is connected to the axial protrusion 871 so as to be disposed in the spring cap 85.

[0051] The end of the support shaft 82 can pass through the shaft sleeve 83 and press the spring cap 85. The spring cap 85 can move rearward until its flange 852 abuts against the spring seat 87. When the spring cap 85 moves forward by the elastic force of the spring and returns to its original position, its flange 852 abuts against the engagement protrusion 843. The engagement protrusion 843 can restrict the spring cap 85 from continuing to move forward. At this time, the top 851 of the spring cap 85 abuts against the shaft sleeve 83.

[0052] When the frying machine automatically cleans the supply mechanism 200, a seal ring 88 is provided between the rear of the shaft sleeve 83 and the limiting sleeve 84 to prevent water from flowing into the shaft sleeve 83 or out of the frame 100. The outer ring of the top 851 of the spring cap 85 can abut against the seal ring 88. Seal structures (not shown) are also provided between the limiting sleeve 84 and the mounting hole 101 and between the spring seat 87 and the mounting hole 101.

[0053] When the user installs the supply mechanism 200, the user first places the support shaft 82 in the shaft sleeve 83 and moves the supply mechanism 200 to the right. At this time, the support shaft 82 compresses the spring cap 85, leaving a surplus space on the left side for the step shaft 81 to engage with the motor output shaft 301. After the engagement is completed, the support shaft 82 is placed in the shaft sleeve 83, and the spring 86 automatically returns the spring cap 85, completing the installation. When the user removes the supply mechanism 200, the user moves the supply mechanism 200 to the right. At this time, the support shaft 82 compresses the spring cap 85, disengaging the step shaft 81 from the output shaft 301, and then the support shaft 82 is pulled out of the shaft sleeve 83, and the spring cap 85 automatically returns, completing the removal.

[0054] This automatic limiting shaft seat structure has strong sealing ability with the frame 100, making it easy to attach and detach the supply mechanism 200, and eliminating the need for extra manual operation steps, which effectively improves the user experience of using the stir fry machine.

[0055] 2) Automatic limiting axle seat structure II

[0056] As shown in Figs. 15 and 16, the shaft seat structure is composed of a shaft sleeve 83, a spring 86, and a spring seat 87, from front to rear. The spring seat 87 is a coaxial double-cylinder structure with an opening at the front side, an outer cylinder 873 of which is fixed to the frame 100, and a circlip base 874 is protruding from the inner peripheral wall of the inner cylinder 872. A frame shaft hole is formed in the front end surface of the shaft sleeve 83. The rear part of the shaft sleeve 83 is a sleeve structure with an opening at the rear side. A limiting protrusion 832 is provided on the outer peripheral wall of the sleeve 831. The limiting protrusion 832 is disposed outside the frame 100. A protruding positioning pillar 833 is further provided on the inner bottom surface of the sleeve 831. The sleeve 831 is provided on the outer peripheral wall of the inner cylinder 872 so as to be relatively movable forward and backward. The front end of the shaft sleeve 83 passes through the mounting hole 101 of the frame 100. The end of the support shaft 82 is disposed in the frame shaft hole in the front end surface of the shaft sleeve 83 and can rotate freely. The spring is connected to the positioning post 833 so as to be disposed in the inner cylinder 872, with its front end abutting the inner bottom surface of the sleeve 831 and its rear end abutting the circlip base 874.

[0057] The end of the support shaft 82 can press the shaft sleeve 83 rearward. The shaft sleeve 83 can move rearward until the inner bottom surface of the sleeve 831 abuts against the front end surface of the inner cylinder 872. When the shaft sleeve 83 moves forward and returns to its original position due to the elastic force of the spring 86, the limiting protrusion 832 abuts against the frame 100. The limiting protrusion 832 can limit the shaft sleeve 83 from continuing to move forward.

[0058] When the frying machine automatically cleans the supply mechanism 200, a seal ring (not shown) is provided between the front end surface of the limiting protrusion 832 and the mounting hole 101 to prevent water from flowing into the shaft sleeve 83 or out of the frame 100. A seal ring (not shown) is also provided between the outer cylinder 873 and the frame 100.

[0059] When the user installs the supply mechanism 200, the user first places the support shaft 82 in the shaft sleeve 83 and moves the supply mechanism 200 to the right. At this time, the support shaft 82 compresses the shaft sleeve 83 to move it to the right, leaving a surplus space on the left side for engaging the step shaft 81 with the motor output shaft 301. After the engagement is completed, the spring 86 automatically returns the shaft sleeve 83, and the installation is completed. When the user removes the supply mechanism 200, the user moves the supply mechanism 200 to the right. At this time, the support shaft 82 compresses the shaft sleeve 83 to disengage the step shaft 81 from the motor shaft, and then the support shaft 82 is removed from the shaft sleeve 83, and the spring 86 automatically returns the shaft sleeve 83, and the removal is completed.

[0060] This automatic limiting shaft seat structure has strong sealing ability with the frame 100, making it convenient to install and remove the supply mechanism 200, without any extra manual operation steps, and with a simple structure, it can effectively save the internal space of the frame 100 and effectively improve the user's experience of using the stir fry machine.

[0061] 3) Automatic limiting axle seat structure III

[0062] 17 and 18, the automatic limiting bearing structure 3 is based on the automatic limiting structure 2 and adds a pressure type magnetic adsorption repulser 890. The repulser 890 is fixed to the repulser mounting position 875 of the inner cylinder 872. After the magnetic sheet 891 used in combination with the repulser 890 is fixed to the positioning post 833, the magnetic sheet 891 is always in an adsorption state with the magnetic adsorption part 8901 of the repulser 890, and the adsorption force therebetween is greater than the elastic force of the spring 86. The spring 86 in the automatic limiting bearing structure 3 is used to assist the repulser 890 in the ejection process to eject the shaft sleeve 83, reduce the influence of the friction force between the inner surface of the sleeve 831 and the outer surface of the inner cylinder 872 during the movement of the shaft sleeve 83, and ensure the stability of the repulser 890 ejecting the shaft sleeve 83. If the elastic force of the resilient device 890 is sufficient to push the shaft sleeve 83 so as to smoothly spring out, the spring 86 need not be provided.

[0063] The repulser 890, for example the repulser 890 of model number ML-30SBR, is a commercially available product, and its function and working principle will not be described here.

[0064] Before the supply mechanism 200 is installed, the repulser 890 is in the initial position (if it is in the ejection position, it can be pressed to set the repulser 890 to the initial position). The user places the supply mechanism 200 in the frame 100 parallel to the axis so as to be located between the motor output shaft 301 and the shaft seat structure, places the support shaft 82 in the shaft sleeve 83 first, and moves the supply mechanism 200 to the right. At this time, the support shaft 82 compresses the shaft sleeve 83 to move it to the right, and the positioning pillar 833 presses the repulser 890 to repel the repulser 890. In the process of the repulser 890 ejecting, the user engages the step shaft 81 with the output shaft 301. After the engagement is completed, the repulser 890 is in the ejection position at this time, and the installation is completed. When the supply mechanism 200 is removed, the supply mechanism 200 is moved to the right. At this time, the support shaft 82 compresses the shaft sleeve 83, and the positioning pillar 833 presses the repulser 890 so as to return the repulser 890 to its initial position, disengaging the step shaft 81 from the output shaft 301, and then the support shaft 82 is removed from the shaft sleeve 83, completing the removal.

[0065] 3) Manual limiting shaft seat structure

[0066] As shown in Figs. 19 and 20, the shaft seat structure mainly consists of a shaft sleeve 83 and a limiting sheet 892 from front to rear. The rear end of the shaft sleeve 83 is inserted into the mounting hole 101 so as to be fixed to the frame 100. The shaft sleeve 83 is formed with a through shaft hole passage 835 penetrating the shaft sleeve 83, and the end of the support shaft 82 moves back and forth inside the through shaft hole passage 835. The front part of the shaft sleeve 83 is formed with a limiting hole 834 penetrating the shaft sleeve 83 along the radial direction of the shaft sleeve 83, and the limiting sheet 892 is inserted into the limiting hole 834. Then, the support shaft 82 is limited so that the step shaft 81 and the output shaft 301 are in a meshed connection state. In order to effectively prevent dust and the like from the outside of the frame 100 from entering the shaft sleeve 83, a protective cover 893 fixed to the frame 100 is further provided at the rear end of the shaft sleeve 83. In order to facilitate the user to take out or insert the limiting sheet 892 from the limiting hole 834, a pull tab 891 is provided at the top of the limiting sheet 892, which is always located on the outside of the shaft sleeve 83. When the frying machine automatically cleans the feeding mechanism 200, a sealing structure (not shown) is provided between the shaft sleeve 83 and the mounting hole 101 and between the protective cover 893 and the mounting hole 101 to prevent water from flowing into the shaft sleeve 83 or out of the frame 100.

[0067] When the user installs the supply mechanism 200, the user first removes the limiting sheet 892 from the limiting hole 834, then places the support shaft 82 in the shaft sleeve 83, moves the supply mechanism 200 to the right, and leaves a surplus space on the left side for engaging the step shaft 81 with the motor output shaft 301. After the engagement is completed, the user manually inserts the limiting sheet 892 into the limiting hole 834, and the installation is completed. At this time, the step shaft 81 and the output shaft 301 are held in an engaged and connected state. When the user removes the supply mechanism 200, the user manually pulls out the limiting sheet 892 from the limiting hole 834, moves the supply mechanism 200 to the right, disengages the step shaft 81 from the output shaft 301, and then removes the support shaft 82 from the shaft sleeve 83, and the removal is completed.

[0068] The manual limiting bearing structure has a strong sealing performance with the frame 100, so that the mounting structure is simple and the production cost can be effectively reduced.

[0069] 5, Electromagnetic Assembly 9

[0070] 1, 2 and 6, an electromagnetic assembly 9 is provided at each position facing the pin 3. The electromagnetic assembly 9 is attached to the outside of the frame 100, and a permanent magnet block 94 is fixed to the front end of the iron core so as to be disposed within the frame 100. When the supply mechanism 200 is in the supply position after being turned 180 degrees, the electromagnetic assembly 9 attracts the pin 3, the movable baffle opens, and the ingredients in the bun frame fall into the frying pan 400, completing the supply.

[0071] As shown in Figs. 7 to 10, the electromagnetic assembly 9 mainly consists of two coils arranged coaxially and spaced apart from each other and one iron core. The front end of the iron core can be extended forward through the coils and placed in the frame 100, and faces the pin 3, and a permanent magnet block 94 is rotatably connected to its front end. The iron core can move back and forth in the two coils. The coil for attracting and moving the iron core forward is the front coil 91, and the coil for attracting and moving the iron core rearward is the rear coil 92. Correspondingly, the iron core 93 in the front coil 91 is provided with a front attracting portion 931, and the iron core 93 in the rear coil 92 is provided with a rear attracting portion 932. The iron core 93 in the space between the two coils is provided with a contact ring 933. A spring is provided on the outside of the iron core 93 to return the iron core 93 when both of the two coils are powered off. In order to reduce the axial space occupied when the spring is compressed, it is preferable to use a tower spring 95. The tower spring 95 has a bottom abutting against the rear end surface of the housing of the front coil 91, and a top abutting against the contact ring 933 of the core 93. The elastic force of the tower spring 95 is greater than that of the return spring 33 of the pin 3. In a state where none of the coils are energized, when the permanent magnet block 94 of the core 93 and the permanent magnet 32 ​​of the pin 3 are attracted to each other, the tower spring 95 moves the pin 3 backward so that the front end surface of the pin 3 is accommodated in the first step 171 and the limit ring 31 abuts against the second step 172.

[0072] As shown in Figures 2 and 8, when the supply mechanism 200 is in the supply position and the front coil 91 is energized, the front adsorption portion 931 of the iron core 93 is adsorbed, the iron core 93 moves forward, the tower-shaped spring 95 is compressed into the contact ring 933, and the permanent magnet block 94 attracts the permanent magnet 32 ​​of the pin 3.

[0073] As shown in Fig. 9, after the front coil 91 is cut off, the tower spring 95 returns the iron core 93 to move it backward. The pin 3 moves backward following the iron core 93 so that its front end face is disposed within the first step 171. Before the limit ring 31 abuts against the second step 172, the pin 3 releases contact with the movable baffle 2, and the movable baffle 2 opens by its own gravity, completing the supply of ingredients in the bun frame.

[0074] As shown in Figures 1 and 10, when the supply mechanism 200 completes the supply and returns to its original position, the movable baffle 2 is covered by the supply port 14 by gravity. The rear coil 92 is energized, the rear suction portion 932 of the core 93 is attracted, and the core 93 moves rearward. The limit ring 31 of the pin 3 is already in contact with the front of the second step 172, so it cannot move rearward together with the core 93. The permanent magnet 32 ​​is separated from the permanent magnet block 94, the return spring 33 of the pin 3 returns the pin 3, the rear coil 92 is cut off, and the return is completed.

[0075] 6. How the feeding mechanism 200 is used in a frying machine

[0076] The motor 300 is preferably a stepping motor. The starting position of the motor 300 is the original position of the feeding mechanism 200 and is the feeding position of the feeding mechanism 200 after a 180 degree clockwise reversal.

[0077] The food case 43 containing the food is placed in the case frame in advance. During the frying process, after the main control center of the frying machine issues a supply command, the supply mechanism 200 rotates 180 degrees axially backward. The movable baffle 2 overlaps the pin 3 due to gravity. The outlet of the food case 43 engages with the movable baffle 2 correspondingly. Each electromagnetic assembly 9 is activated according to the requirement of the supply command. The front coil 91 is energized, and the permanent magnet 32 ​​at the front end of the iron core 93 and the permanent magnet 32 ​​at the rear end of the pin 3 are attracted to each other. The front coil 91 is powered off, and the pin 3 moves backward so that its front end surface is accommodated in the first step 171, and is released from contact with the movable baffle 2, and the movable side of the movable baffle 2 rotates downward due to gravity and overlaps the limit block 53 of the guide groove 5. At this time, the food also slides down into the frying pan 400 through the movable baffle 2 and the guide groove 5 due to gravity, completing the supply of one bun frame. Each electromagnetic assembly 9 correspondingly controls each van door so that the supply is completed in an orderly manner in response to the supply command from the main control center.

[0078] After the stir-frying is completed, the main control center of the stir-frying machine issues a return command. The feed mechanism 200 rotates 180 degrees forward and returns to its original position. Each movable baffle 2 is covered by the feed port 14 by gravity. The rear coils 92 in all the electromagnetic assemblies 9 are energized, and the permanent magnets 32 of the pins 3 are released from the attraction with the permanent magnet blocks 94 of the iron cores 93. The return springs 33 return the pins 3. The rear coils 92 are powered off, and the tower springs 95 return the iron cores 93, completing the return operation.

[0079] In addition, the supply mechanism 200 in this embodiment is applicable only to the food case 43 having the same outlet as the supply inlet 14 of the base frame 1. If the outlet of the food case 43 is different from that in the embodiment of the present invention, the shape, height and size of the base frame 1, the case frame, the guide groove 5 and the movable baffle 2 can be adjusted based on the outlet and the shape of the case body.
