DETAILED DESCRIPTION

[0036] The unloading mechanism used in the cooking machine of the present invention does not need to perform a flipping action in the inner cavity of the cooking machine (the inner cavity is a cavity enclosed by the inner shell of the cooking machine), and can realize the unloading of ingredients in the ingredient box 5 in sequence. It simplifies the mechanical structure and can reduce the space occupied by the unloading mechanism in the inner cavity of the cooking machine, thereby improving space utilization, reducing cooking time, and improving cooking efficiency.

[0037] The blanking mechanism is composed of a box support assembly 1, a supporting mechanism 2, a lock tongue assembly 3 and a lock tongue control mechanism 4.

[0038] 1. Box bracket assembly 1

[0039] The box support assembly 1 is an independent module component. The box support assembly 1 can be placed on the supporting mechanism 2 together with the food box 5, and can also be taken out together with the food box 5 for cleaning.

[0040] like Figure 1 and Figure 2 As shown, the box support assembly 1 is mainly composed of a base frame 11, a movable baffle 12 and a box frame 13.

[0041] 1. The base frame 11 is composed of an outer frame 111, a crossbeam 112 and a longitudinal beam 113, and a discharge port 114 is formed between the three, which is adapted to the size and number of the discharge port 51 of the food box 5. Preferably, the food box 5 in the present invention is a four-compartment vegetable box with four discharge ports 51, and correspondingly, there are also four discharge ports 114.

[0042] Specifically, the cross-section of the outer frame 111 is an inverted "L" shape, which is divided into an inner side plate 1111 and a top plate 1112 (with Figure 2 The paper surface is the reference direction of the upper (top), lower (bottom), left, right, inside, outside, front and back of the base frame 11, the same below), and the inner plate 1111, the cross beam 112 and the longitudinal beam 113 enclose the discharge port 114.

[0043] Further, such as Figure 1 and Figure 3 As shown, in order to make the outer frame 111 more beautiful and facilitate the installation of other components, the outer frame 111 is also provided with an outer plate 1113 and a bottom plate 1114. The inner plate 1111, the top plate 1112, the outer plate 1113 and the bottom plate 1114 are enclosed and connected. For the convenience of assembly, the bottom plate 1114 can be detachably installed on the inner plate 1111 and the outer plate 1113.

[0044] In order to facilitate the removal of the cartridge holder assembly 1 , a handle 115 is provided on the outer side plate 1113 on the front side of the outer frame 111 .

[0045] The outer frame 111 may also be a solid frame with a certain thickness, and a recessed position (not shown in the figure) for mounting the locking tongue assembly 3 is provided on the outer frame 111 .

[0046] 2. Movable baffle 12

[0047] Above each discharge port 114, there is a corresponding movable baffle 12 with an area slightly larger than the area of ​​the discharge port 114. The hinged ends 121 of the two movable baffles 12 on the two discharge ports 114 at the front of the outer frame 111 are movably connected to the inner plate 1111 through a connecting shaft 116. Specifically, the two ends of the connecting shaft 116 are respectively fixed to the inner plates 1111 on the left and right sides of the outer frame 111 and close to the inner plate 1111 on the front side of the outer frame 111, and the edge of the movable end 122 is overlapped on the horizontal On the beam 112; the hinged ends 121 of the two movable baffles 12 on the two discharge ports 114 at the rear of the outer frame 111 are movably connected to the inner plate 1111 through another supporting shaft 116. Specifically, the two ends of the supporting shaft 116 are respectively fixed to the inner plates 1111 on the left and right sides of the outer frame 111 and are close to the cross beam 112 or placed on the cross beam 112, and the edge of its movable end 122 is overlapped on the narrow baffle 117 extending forward from the inner plate 1111 on the rear side of the outer frame 111.

[0048] The advantage of this design is that after the box holder assembly 1 is flipped 180 degrees, all the movable baffles 12 can rotate clockwise around the axis in the process from the closed discharge port 114 state to the open discharge port 114 state, and rotate counterclockwise around the axis in the process from the open discharge port 114 state to the closed discharge port 114 state. When all the movable baffles 12 are in the state of opening the discharge port 114 and the box holder assembly 1 needs to be taken out, it is only necessary to pull the box holder assembly 1 outward, and the movable baffles 12 can rotate counterclockwise around the axis under the reverse push of the supporting mechanism 2, so that the box holder assembly 1 can be smoothly taken out (when the supporting mechanism 2 is a square frame 21a, and the front side of the square frame 21a is open, or when the supporting mechanism 2 is a guide groove 21b structure, this situation does not exist).

[0049] 3. Box rack 13

[0050] The box frame 13 is fixed to the bottom of the base frame 11 and is used to receive the food box 5. The box frame 13 has the following structures:

[0051] 1) If Figure 3 As shown, the box rack 13 is a box 131a with an open top and front side. The top edge of the box 131a is fixed to the bottom edge of the inner plate 1111 or the bottom surface of the bottom plate 1114, and the food box 5 is pushed into the box 131a from the front side.

[0052] The advantage of this structure is that the box 131a can fully wrap the entire food box 5, and can better define and support the food box 5 during the flipping process of the box support assembly 1.

[0053] 2) If Figure 4As shown, the box rack 13 is composed of two independent support frames 131b with a "Z"-shaped or inverted "U"-shaped cross-section. The two support frames 131b are symmetrically arranged at the bottom of the left side frame 1115 (composed of the inner plate 1111 and the top plate 1112 on the left side or composed of the inner plate 1111, the top plate 1112, the outer plate 1113 and the bottom plate 1114 on the left side) and the right side frame 1116 (the right side frame 1116 is the same as the left side frame 1115) of the outer frame 111, and the flanges 52 on the left and right sides of the top surface of the food box 5 are pushed into the support frames 131b to receive the food box 5.

[0054] The advantages of this structure are: simple structure, cost saving, and at the same time reducing the overall weight of the box bracket assembly 1, making the flipping operation easier.

[0055] Through the above two structures, the food box 5 can be fixed on the base frame 11, and the discharge port 51 of the food box 5 is connected to the feed opening 114 in a one-to-one correspondence.

[0056] Before placing the box support assembly 1 with the food box 5 into the supporting mechanism 2, first turn the box support assembly 1 180 degrees outside the cooking machine so that the top surface of the box support assembly 1 faces downward, and at the same time, the discharge port 51 of the food box 5 is inverted on the movable baffle 12, and then pushed into the supporting mechanism 2.

[0057] 2. Supporting Institution 2

[0058] The supporting mechanism 2 is used to support the box bracket assembly 1 above the wok mouth in the inner cavity of the cooking machine.

[0059] The supporting mechanism 2 has the following two structures:

[0060] 1. Square frame 21a

[0061] like Figure 5 As shown, the supporting mechanism 2 is a square frame 21a, and the left side, rear side and right side (with Figure 5 The paper surface is the reference direction of the upper (top), lower (bottom), left, right, inside and outside of the square frame 21a, the same below) and is provided with a downwardly recessed step 211a. The front side of the square frame 21a is an open notch. The box holder assembly 1 is inserted into the square frame 21a through the notch and placed on the step 211a (the top plate 1112 abuts against the step 211a).

[0062] The left and right sides of the square frame 21a are fixedly connected to the inner wall of the inner shell of the cooking machine through a connecting structure 214a. Preferably, in order to make the supporting mechanism 2 more stably fixed in the cooking machine, there are four connecting structures 214a, which are respectively arranged at the four diagonal positions on the left and right sides of the square frame 21a.

[0063] In order to further fix the box holder assembly 1 placed on the supporting mechanism 2, a horizontal beam 212a connecting the left and right sides of the square frame 21a is provided at the open part of the square frame 21a, and the top surface of the horizontal beam 212a is flush with the table surface of the step 211a. An arc-shaped boss 213a is provided on the top surface of the horizontal beam 212a to prevent the box holder assembly 1 pushed into place from sliding out.

[0064] 2. Guide groove 21b

[0065] like Figure 6 As shown, the supporting mechanism 2 can also be composed of two independent and oppositely arranged guide grooves 21b, the two guide grooves 21b are respectively fixed to the left inner wall and the right inner wall of the inner shell, and the notches of the two guide grooves 21b are arranged facing each other. Furthermore, a limit baffle 211b is provided at the rear end of each guide groove 21b to prevent the box holder assembly 1 from being pushed in further. After the box holder assembly 1 is pushed in, the left side frame 1115 and the right side frame 1116 of the outer frame 111 are snapped into the guide grooves 21b on the corresponding sides.

[0066] In order to ensure that the food falling from the discharge port 114 falls accurately into the wok, a discharge hopper 6 is provided below the supporting mechanism 2. The discharge hopper 6 is funnel-shaped, and the upper port of the discharge hopper 6 is fixedly connected to the bottom surface of the square frame 21a or the bottom edge of the card slot and the diameter of the upper port is greater than or equal to the diameter of the square frame 21a, or the diameter of the upper port of the discharge hopper 6 is greater than or equal to the diameter enclosed by the card slot, and the diameter of the lower port of the discharge hopper 6 is less than or equal to the diameter of the pot mouth and is located directly above the pot mouth of the wok. When the movable baffle 12 is opened for discharge, the food can be diverted into the wok through the discharge hopper 6.

[0067] 3. Lock tongue assembly 3 and lock tongue control mechanism 4

[0068] like Figure 7 As shown, the locking tongue assembly 3 can close the movable baffle 12 on the discharge port 114 when the box bracket assembly 1 is flipped 180 degrees to prevent the food in the food box 5 from falling. The locking tongue control mechanism 4 is used to cooperate with the locking tongue assembly 3 to control the movable baffle 12 to open the discharge port 114, thereby realizing the independent discharge of food in the four compartments of the food box 5 in sequence.

[0069] The lock tongue assembly 3 is installed on the left side frame 1115 and the right side frame 1116 of the outer frame 111 at positions corresponding to the movable ends 122 of the movable baffles 12, and each movable baffle 12 is correspondingly provided with a lock tongue assembly 3; the lock tongue control mechanism 4 is installed on the supporting mechanism 2 and is arranged one-to-one in correspondence with the lock tongue assembly 3 (when the box bracket assembly 1 is on the supporting mechanism 2 and pushed into place, the lock tongue assembly 3 corresponds to the position of the lock tongue control mechanism 4).

[0070] The lock tongue assembly 3 and the lock tongue control mechanism 4 have the following two structures:

[0071] 1. Hook structure

[0072] like Figures 8-10 As shown, this structure is mainly applicable to the structure when the supporting mechanism 2 is a square frame 21a, specifically as follows:

[0073] 1) Lock tongue assembly 3

[0074] The bolt assembly 3 is mounted on the outer side of the inner plate 1111 at a position corresponding to the movable end 122. A lock plate hole 35 is provided on the inner plate 1111. The bolt assembly 3 includes a fixing frame 31a, a body 32a, a return spring 33 and a pulled member. The fixing frame 31a includes a left side plate 311a, a right side plate 312a and a rear side plate 313a (with Figure 8 The paper surface is a reference for the direction of the lock tongue assembly 3. The side of the body 32a facing the movable baffle 12 is the front, and the side of the body 32a away from the movable baffle 12 is the back. The left, right, top and bottom of the body 32a are determined accordingly (the same below). The left plate 311a and the right plate 312a are both provided with a long groove 3111a with one end open. Correspondingly, sliders 323a are provided on the left and right sides of the body 32a. The sliders 323a are inserted into the long grooves 3111a from the corresponding openings and move back and forth in the long grooves 3111a to limit the body 32a to make forward and backward linear motion on the same horizontal plane. A tongue 321a that can pass through the lock plate hole 35 is provided on the front end face of the main body 32a, and a blind hole 322a extending into the main body 32a is provided on the rear end face of the main body 32a. The return spring 33 is placed in the blind hole 322a, and the outer end of the return spring 33 (the end placed outside the blind hole 322a) abuts against the rear side plate 313a. The pulled member is a pulled plate 34a arranged at a rear position on the top surface of the main body 32a and extending upward. A window 36 is provided on the top plate 1112 to allow the main pulling member in the lock tongue control mechanism 4 to pass through and apply an outward force to the pulled plate 34a.

[0075] Under the elastic action of the return spring 33, the front end face of the main body 32a abuts against the outer surface of the inner plate 1111, and at the same time, the tongue 321a is pushed out of the lock plate hole 35 and placed on the movable baffle 12 to clamp the edge of the movable end 122 between the lock tongue and the crossbeam 112 or the narrow strip. The main traction member pulls the pulled plate 34a to move outward so that the tongue 321a is separated from the movable baffle 12, thereby realizing the opening of the movable baffle 12 (the movable end 122 of the movable baffle 12 falls due to gravity to open the discharge port 114).

[0076] 2) Lock tongue control mechanism 4

[0077] The lock tongue control mechanism 4 is a push-pull electromagnet, which includes an electromagnetic coil 41a, an iron core 42a and a spring 43a. The electromagnetic coil 41a is arranged on the outside of the connecting wall 215a between the top surface of the square frame 21a and the step 211a. The built-in end of the iron core 42a (the end of the iron core 42a inside the electromagnetic coil 41a when the electromagnetic coil 41a is not energized) is inserted into the electromagnetic coil 41a, and a baffle 421a is provided on the iron core 42a near the external end (the end of the iron core 42a outside the electromagnetic coil 41a when the electromagnetic coil 41a is not energized). The spring 43a is sleeved between the baffle 421a and the electromagnetic coil. On the iron core 42a between the rings 41a, one end of the spring 43a abuts against the electromagnetic coil 41a, and the other end abuts against the baffle 421a. Under the action of the spring 43a, the baffle 421a is pressed against the limit plate 216a extending downward from the outer surface of the connecting wall 215a. The main traction member is arranged at the outer end of the iron core 42a. The main traction member is an "L"-shaped hook, which consists of a connecting plate 44a and a hook plate 45a. The hook passes through the connecting wall 215a and is placed on the step 211a. The top surface of the connecting plate 44a is lower than the table surface of the step 211a. The hook plate 45a extends upward and is placed on the front side of the pulled plate 34a.

[0078] like Figure 4 、 Figure 5 and Figure 11 As shown, to facilitate smooth insertion of the cartridge holder assembly 1 onto the support mechanism 2 within the cooking machine, four pulleys 14 are provided diagonally on the left and right sides 1115 and 1116 of the outer frame 111. These pulleys 14 are rotatably connected to the outer frame 111 via rotating shafts. A portion of the pulley body protrudes above the top plate 1112 of the outer frame 111, and the height of the protruding portion is greater than the height of the table surface where the hook plate 45a extends upward from the step 211a. Correspondingly, a recessed portion 217a is provided on the table surface to mate with the wheel structure.

[0079] The box support assembly 1 with the food box 5 inserted is turned 180 degrees outside the cooking machine (from left to right or from right to left), so that the food box 5 is pushed into the supporting mechanism 2 with its discharge port 51 upside down on the movable baffle 12 (that is, the outer frame 111 is with the top plate 1112 facing downward), and the pulley 14 slides inward along the table surface so that the top plate 1112 of the outer frame 111 is higher than the upper end of the hook plate 45a. When the box support assembly 1 is pushed into place, the pulley 14 falls into the recessed position 217a. At this time, the top plate 1112 of the outer frame 111 is in contact with the upper end of the hook plate 45a. On the table top, the front top of the outer frame 111 abuts against the boss, and the hook plate 45a is inserted into the window 36 and connected to the pulled plate 34a. The hook plate 45a moves in the direction of the compression spring 43a under the interaction of the electromagnetic coil 41a and the iron core 42a, thereby driving the pulled plate 34a to move outward so that the main body 32a moves in the direction of the compression return spring 33, and finally drives the tongue 321a to disengage from the movable baffle 12, so that the movable baffle 12 rotates downward around the supporting shaft 116 under the action of the food and its own gravity to open the discharge port 114.

[0080] When the cartridge holder assembly 1 needs to be taken out, the handle 115 is pulled outward, and the movable baffle 12 is automatically closed upward under the action of the transverse beam 212 a , so that the cartridge holder assembly 1 is taken out.

[0081] 2. Permanent magnet 45b attraction structure

[0082] like Figure 12-15 As shown, this structure is applicable when the supporting mechanism 2 is a square frame 21a, and is also applicable when the supporting mechanism 2 is a guide groove 21b. The specific structure is as follows:

[0083] 1) Lock tongue assembly 3

[0084] The locking tongue assembly 3 includes a fixing member 31b, a pin 32b, a return spring 33 and a pulled member.

[0085] The fixing member 31b is fixed to the bottom surface of the top plate 1112 at a position corresponding to the movable end 122. The fixing member 31b is divided into an upper member 311b and a lower member 312b. The upper member 311b and the lower member 312b are fixed by screws. There is a hollow channel 313b therebetween. An annular front step 314b and a rear step 315b are respectively provided on the front and rear inner peripheral walls of the hollow channel 313b (the side of the fixing member 31b close to the movable baffle 12 is the front, and the side away from the movable baffle 12 is the rear). The pin 32b is placed in the hollow channel 313b, and an annular baffle 321b that can be stuck on the front step 314b is fixed to the front part of the pin 32b. The return spring 33 is sleeved on the outer wall of the pin 32b and is between the annular baffle 321b and the rear step 315b. The front end of the pin 32b passes through the lock plate hole 35 and is placed on the movable end 122. The pulled part is a permanent magnet block 34b arranged on the rear end face of the pin 32b. Specifically, the permanent magnet block 34b is connected to the pin 32b by a screw connection.

[0086] The pin 32b can move forward and backward in the fixing member 31b, and the movable distance is the length between the front step 314b and the rear step 315b.

[0087] 2) Lock tongue control mechanism 4

[0088] The lock tongue control mechanism 4 is an electromagnet assembly.

[0089] When the electromagnet assembly is installed in the square frame 21a, the specific structure is as follows:

[0090] The electromagnet assembly is arranged on the outside of the connecting wall 215a and at a position opposite to the lock tongue assembly 3. The electromagnet assembly is mainly composed of two coaxial and spaced coils, a special iron core 43b and a main traction member. The main traction member is arranged at the front end of the special iron core 43b (the end close to the lock tongue assembly 3 is the front, and the end away from the lock tongue assembly 3 is the rear, the same below). The main traction member is a permanent magnet 45b. The special iron core 43b passes through the two coils and the main traction member is placed in the through hole on the connecting wall 215a, so that the main traction member is facing the pulled member, and the special iron core 43b can move back and forth in the two coils.

[0091] The coil used to attract and move the special iron core 43b forward is the front coil 41b, and the coil used to attract and move the special iron core 43b backward is the rear coil 42b. Correspondingly, a front attracting portion 431b is provided on the special iron core 43b within the front coil 41b, and a rear attracting portion 432b is provided on the special iron core 43b within the rear coil 42b. A resistance ring 433b is provided on the special iron core 43b between the two coils. A spring is provided on the outer shell of the special iron core 43b, which can reset the special iron core 43b when both coils are de-energized. To reduce the axial space occupied by the spring when compressed, a conical spring 44b is preferably used. The bottom of the conical spring 44b abuts the rear end surface of the outer shell of the front coil 41b, and the top abuts the resistance ring 433b on the special iron core 43b (the thin end of the conical spring 44b is the top, and the thick end is the bottom). The elastic force of the conical spring 44b is greater than the elastic force of the return spring 33 on the pin 32b. When the coils are not energized, when the main traction member and the traction member are attracted (the permanent magnet 45b and the permanent magnet block 34b are attracted), the conical spring 44b drives the pin 32b to move backward so that the front end of the pin 32b is accommodated in the hollow channel 313b of the fixing member 31b and the annular baffle 321b abuts against the rear step 315b.

[0092] When the box bracket assembly 1 is placed on the square frame 21a, when the front coil 41b is energized, the front coil 41b acts on the front attraction part 431b, causing the special iron core 43b to move forward, and the conical spring 44b is compressed by the resistance ring 433b, and the main traction part is attracted to the traction part (the permanent magnet 45b is attracted to the permanent magnet block 34b).

[0093] like Figure 15 As shown, after the front coil 41b is powered off, the conical spring 44b resets the special iron core 43b and moves it backward, and the pin 32b moves backward following the iron core 42a. The annular baffle 321b abuts in front of the rear step 315b, and the front end of the pin 32b disengages from the movable baffle 12. The movable baffle 12 opens due to its own gravity, completing the unloading of food from the food box 5.

[0094] When all the compartments of the food box 5 have been unloaded and the box bracket assembly 1 needs to be taken out, the rear coil 42b is energized, and the rear coil 42b acts on the rear suction part 432b, the special iron core 43b moves backward, and the limiting ring on the pin 32b has abutted in front of the rear step 315b and cannot move backward with the iron core 42a. The pulled part and the main pulling part are pulled apart, and the reset spring 33 on the pin 32b resets the pin 32b. The front end of the pin 32b passes through the lock plate hole 35, the rear coil 42b is de-energized, and the box bracket assembly 1 can be taken out.

[0095] When the electromagnet assembly is installed in the guide groove 21b structure, the structure and working principle of the electromagnet assembly are the same, the difference lies in the different installation positions, specifically:

[0096] The electromagnet assembly is arranged on the outer wall of the inner shell corresponding to the bottom of the guide slot 21b. The iron core 42a passes through the inner shell and the bottom of the guide slot 21b to attract the main traction member and the traction member.
