Description

Technical Field

[0001] The present invention relates to a cooking machine, in particular to a mechanism for controlling the opening and closing of a compartment door in a feeding device of the cooking machine. Background Art

[0002] The applicant previously submitted a utility model patent application (application date 2021.07.30, application number 202121755218.X, titled "A feeding mechanism for a cooking machine", authorization announcement date 2022.02.15, announcement number CN 215820614U), which discloses a feeding mechanism for a cooking machine. The feeding mechanism can push or attract the pins set in the left and right frames of the base frame through an electromagnetic component to control the opening or closing of the compartment door, thereby realizing the feeding action during cooking of the cooking machine.

[0003] However, the above structure has the following shortcomings:

[0004] 1. The electromagnetic component consists of two coaxial coils and an iron core. There are no standard parts on the market. Customization is required, which has high production costs.

[0005] 2. The pins used to prevent the door from opening are set on the left and right frames of the base frame. The electromagnetic component and the pins are attracted by magnets. After a period of use, the magnets may rust or demagnetize in a humid environment, resulting in poor connection between the electromagnetic component and the pins, causing the door to be unable to open accurately and the feeding mechanism to be unable to accurately feed the food into the wok during cooking.

[0006] 3. The pin is blocked at the side of the door. When there are many and heavy ingredients in the compartment, the side without the pin is easily deformed, causing the ingredients to be exposed from the other side when the door is not opened. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a mechanism for controlling the opening and closing of a bin door, which has a simple structure, low cost and can ensure that the bin door is in a horizontal state when closed, and a feeding device with the mechanism.

[0008] In order to solve the above technical problems, the technical solutions of the present invention are as follows:

[0009] A mechanism for controlling the opening and closing of a bin door in a feeding device of a cooking machine is provided, comprising a base frame provided with a plurality of feeding openings, a bin door which can close the feeding opening being provided on each feeding opening, a door lock patch which extends outward being provided in the middle position of a movable side of the bin door, and a door lock clip which closes the bin door at the feeding opening being provided on the top surfaces of the front and rear frames of the base frame and at a position opposite to the door lock patch, the door lock clip being installed on a transmission assembly, and the transmission assembly, driven by a corresponding driving component, enables the door lock clip to move linearly or rotate out of the obstruction of the door lock patch.

[0010] Furthermore, the driving component is a push-pull electromagnet, which is installed on the cooking machine casing. The transmission assembly consists of a mounting seat arranged on the top surface of the base frame and shaped like a long rod, and a push rod that can be inserted into the mounting seat and can move linearly back and forth therein.

[0011] Furthermore, the door lock card is sleeved on the push rod, and the push-pull electromagnet can push the push rod, and the push rod drives the door lock card to move linearly, so that it is free from the obstruction of the door lock patch.

[0012] Furthermore, the door lock card is sleeved on the push rod, and a pin parallel to the push rod is provided on the push rod. The pin abuts against the bottom of the door lock card. The push-pull electromagnet can push the push rod so that the pin is disengaged from the door lock card. The door lock card can rotate freely around the push rod due to its own gravity and get rid of the obstruction of the door lock patch.

[0013] Furthermore, the door lock card is provided with a locking position that can lock the door lock card in an open state.

[0014] A blanking device is provided, comprising a base frame and a warehouse door that can be opened or closed, wherein a door lock patch is provided on the warehouse door, and a transmission assembly and a door lock card are installed on the front and rear frames of the base frame. When driven by a corresponding driving component, the transmission assembly carries the door lock card in a linear movement or rotational manner to break away from the obstruction of the door lock patch.

[0015] Compared to the prior art, the present invention uses a push-pull electromagnet to push a push rod, causing the door lock latch to move linearly or rotate, thereby opening the door of the unloading device and enabling unloading. The present invention positions the door lock latch in the middle of the movable side of the door, which in turn increases the strength of both sides of the door. This effectively overcomes the prior art defect of the door being easily deformed by the weight of the food inside the door when only one side is supported and the other side is away from the support point. The push-pull electromagnet used in the present invention can be a standard component, effectively saving production costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0037] As shown in Figures 1 to 18, the unloading device of the cooking machine generally includes a base frame 12 and several unloading ports 13 arranged on the base frame. A bin door 14 is provided on each unloading port 13. The bin door 14 is used to block the unloading port 13 to prevent the food at the unloading port 13 from falling. When the food at the unloading port 13 needs to be put into the wok, the bin door 14 needs to be opened.

[0038] The mechanism for controlling the opening and closing of the compartment door 14 in the cooking machine unloading device 1 of the present invention primarily comprises a transmission assembly 3 and a door lock fixture 33. The transmission assembly 3 is mounted on the upper surfaces of the front and rear frames of the base frame 12 of the unloading device 1. The door lock fixture 33 is sleeved onto the transmission assembly 3, controlling the opening and closing of the compartment door 14 through the transmission assembly 3.

[0039] The specific structure of the mechanism for controlling the opening and closing of the cabin door 14 of the present invention is as follows:

[0040] As shown in Figures 1 and 2, four discharge openings 13 are provided on the base frame 12, and a warehouse door 14 that can close the discharge opening 13 is provided on each discharge opening 13. The specific technical scheme of the warehouse door 14, the base frame 12 and the connection structure between the two can be found in the patent mentioned in the background technology: 202121755218.X.

[0041] As shown in Figures 1 and 5 , the inner side of the door 14 is hinged to the base frame 12, while the outer side (the side facing the geometric center of the base frame 12 is the inner side, and the side facing away from the center is the outer side, similarly hereinafter) is the movable side. A door lock patch 142 extends outward from the middle of this movable side. The door lock latch 33 contacts and presses against this door lock patch 142. After the discharge device 1 rotates 180 degrees, the door lock latch 33 causes the door 14 to abut and close against the discharge opening 13. Because the door lock latch 33 is supported in the middle of the movable side of the door 14, the left and right sides of the door 14 are evenly stressed, effectively preventing deformation of the door 14.

[0042] The driving component for driving the transmission assembly 3 is a push-pull electromagnet 2. The push-pull electromagnet 2 is a standard part sold on the market with low production cost. It is installed on the cooking machine casing. The push-pull electromagnet 2 can push the transmission assembly 3 so that the door lock card 33 is disengaged from the door lock patch 142 on the compartment door 14 in a linear or rotational manner.

[0043] 1. Linear movement

[0044] As shown in Figures 5 to 11 , the transmission assembly 3 includes a mounting base 31 and a push rod 32. The mounting base 31 is a long, rod-shaped structure that is screwed to the front and rear frames of the base frame 12. The left and right sides of the mounting base 31 are respectively provided with a rod hole 311, a clamping member mounting position 312, and a mounting channel 313 for the spring 34. The push rod 32 is a solid cylindrical rod. Its front end (using Figure 6 as an example, the end of the push rod away from the push-pull electromagnet is the front end, and the end closer to the push-pull electromagnet is the rear end, similarly below) can be sequentially inserted through the rod hole 311, the clamping member mounting position 312, and the mounting channel 313 for the spring 34 to be placed within the mounting base 31.

[0045] As shown in Figure 11 , the door lock fixture 33 consists of a locking portion 331 and a connecting portion 332. The locking portion 331 is an inverted L-shaped block, while the connecting portion 332 is a hollow cylindrical tube, perpendicularly positioned and fixedly connected to the long side of the L-shaped block. The locking portion 331 and the connecting portion 332 can be integrally formed. The connecting portion 332 is positioned within the fixture mounting position 312. The front end of the push rod 32 passes through the rod hole 311, the connecting portion 332, and the spring 34 installed in the spring 34 mounting channel 313. A nut or a latch is inserted at the front end of the push rod 32, securing it within the mounting seat 31. The door lock fixture 33 can reciprocate within the fixture mounting position 312 along the axial direction of the push rod 32.

[0046] Preferably, as shown in Figures 6 and 8 , a round block 321 is fixed to the rear end of the push rod 32 to increase the contact area with the push-pull electromagnet 2 and effectively reduce installation precision. As shown in Figures 3 and 4 , the short side of the L-shaped block of the lock portion 331, located near the door lock patch 142 when the door lock latch 33 is in the open position, is provided with an inclined guide surface. This effectively reduces the mating precision between the door lock latch 33 and the door lock patch 142 when the door lock latch 33 is reset (see below).

[0047] As shown in Figures 7 and 9, a boss 322 is provided on the push rod 32, and the sleeve portion 332 abuts against the boss 322. When the push rod 32 is pushed inward (taking Figure 6 as an example, the direction pointing to the geometric center of the mounting seat 31 is considered inward, and the direction away from the center is considered outward, the same below), the push rod 32 carries the door lock card 33 to compress the spring 34 and move linearly within the card mounting position 312.

[0048] The door lock card 33 moves linearly to open and close the door 14:

[0049] When the cooking machine needs to unload, the unloading device 1 will rotate 180 degrees to the unloading position (not shown). When the compartment door 14 needs to be opened to unload, the corresponding push-pull electromagnet 2 will receive the unloading instruction and open, pushing the push rod 32 inward (see Figure 8), the push rod 32 drives the door lock card 33 to move linearly inward and compress the spring 34 (see Figure 9), so that the door lock card 33 is free from the obstruction of the door lock patch 142 (see Figure 4), and the warehouse door 14 can rotate around the hinge axis due to its own gravity and the gravity of the dishes, thereby opening the unloading port 13 and completing the unloading action of the unloading device 1. The push-pull electromagnet 2 is closed and reset (see Figure 6), and the push rod 32 and the door lock card 33 are reset due to the reset of the spring 34 (see Figure 7).

[0050] After the unloading device 1 completes unloading, it rotates 180 degrees in the opposite direction. The door lock patch 142 of the warehouse door 14 overlaps the door lock card 33 due to its own gravity. When the push-pull electromagnet 2 receives the instruction to close the warehouse door 14, it pushes the push rod 32 inward, causing the door lock card 33 to move linearly and break away from the contact with the door lock patch 142 overlapping it. At this time, the warehouse door 14 covers the unloading port 13 due to its own gravity, the push-pull electromagnet 2 is closed, and the push rod 32 and the door lock card 33 are reset under the action of the spring 34, so that the door lock card 33 contacts the door lock patch 142 (see Figure 3).

[0051] 2. Rotation method

[0052] As shown in Figures 12 to 15 , the transmission assembly 3 includes a mounting base 31 and a push rod 32. The mounting base 31 is a long, rod-shaped structure that is screwed to the front and rear frames of the base frame 12. The left and right sides of the mounting base 31 are respectively provided with a rod hole 311, a clamping member mounting position 312, and a mounting channel 313 for the spring 34. The push rod 32 is a solid cylindrical rod. Its front end (using Figure 12 as an example, the end of the push rod away from the push-pull electromagnet is the front end, and the end closer to the push-pull electromagnet is the rear end, similarly below) can be sequentially inserted through the rod hole 311, the clamping member mounting position 312, and the mounting channel 313 for the spring 34 to be placed within the mounting base 31.

[0053] As shown in Figures 15 to 18 , the door lock fixture 33 consists of a locking portion 331 and a sleeve portion 332. The locking portion 331 is an inverted L-shaped block, while the sleeve portion 332 is a hollow cylindrical tube, perpendicularly positioned and fixedly connected to the long side of the L-shaped block. The locking portion 331 and the sleeve portion 332 can be integrally formed. The sleeve portion 332 is positioned within the fixture mounting position 312. The front end of the push rod 32 passes through the rod hole 311, the sleeve portion 332, and the spring 34 installed in the spring 34 mounting channel 313. A nut or a latch is sleeved on the front end of the push rod 32, securing it within the mounting seat 31. The door lock fixture 33 can rotate around the push rod 32 within the fixture mounting position 312.

[0054] 12 and 15 , a round block 321 is fixedly connected to the rear end of the push rod 32 to increase the contact area with the push-pull electromagnet 2 and effectively reduce the installation accuracy.

[0055] As shown in Figures 15 to 18, a pin 35 is sleeved on the push rod 32. The pin 35 is arranged parallel to the push rod 32 and is located in front of the door lock clamp 33. The pin 35 and the push rod 32 can be fixedly connected by screws, bayonets, etc.; the pin 35 abuts against the lower side of the "L"-shaped long side of the sleeve 332, so that the door lock clamp 33 is blocked and cannot rotate around the push rod 32. A latching position 333 is provided above the long side of the "L" shape of the socket portion 332. When the push-pull electromagnet 2 is opened, the push rod 32 is pushed to drive the pin 35 to move inward, so that the pin 35 is separated from the socket portion 332, and the door lock card 33 can rotate around the push rod 32 due to its own gravity. After the push-pull electromagnet 2 is closed, the push rod 32 and the pin 35 are reset due to the return of the spring 34. At this time, the pin 35 can be inserted into the latching position 333, so that the door lock card 33 remains in the open state.

[0056] The door lock card 33 rotates to open and close the door 14:

[0057] When the cooking machine needs to unload food, the unloading device 1 will rotate 180 degrees to the unloading position (not shown in the figure). When the compartment door 14 needs to be opened for unloading, the corresponding push-pull electromagnet 2 will receive the unloading instruction and open, pushing the push rod 32 inward. The push rod 32 drives the pin 35 to move linearly inward and compress the spring 34, so that the pin 35 is free from the obstruction of the door lock card 33. The door lock card 33 rotates around the push rod 32 under its own gravity, the compartment door 14 and the gravity of the food. The lock part 331 is free from the obstruction of the compartment door 14 (see Figure 14), the compartment door 14 is opened, the unloading device 1 completes the unloading action, the push-pull electromagnet 2 is closed and reset, the push rod 32 and the pin 35 are reset due to the reset of the spring 34 (see Figure 17). At this time, the pin 35 is inserted into the card position 333, fixing the door lock card 33 in the open position (see Figure 18).

[0058] After the unloading device 1 completes unloading, it rotates 180 degrees in the opposite direction. The warehouse door 14 covers the unloading port 13 due to its own gravity. When the push-pull electromagnet 2 receives the command to close the warehouse door 14, it pushes the push rod 32 inward, causing the pin 35 to move inward linearly and disengage from the latch 333. The door lock card 33 resets due to its own gravity and contacts the door lock patch 142. The push-pull electromagnet 2 is closed. At this time, the pin 35 resets to the bottom of the door lock card 33 (see Figure 16), fixing the door lock card 33 in the closed position (see Figure 13).

[0059] It can be understood that the length of the push rod 32 and the installation position of the door lock card 33 are different due to the different corresponding setting positions of the door lock patch 142. In this embodiment, the sizes of the warehouse doors 14 are different and the door lock patch 142 is set at the central position of the movable side of the warehouse door 14. Therefore, the installation positions of the door lock cards 33 are different, and the lengths of the push rods 32 are also different, but the internal movement mechanism of the transmission assembly 3 is the same, which will not be repeated here.

[0060] The feeding device 1 of the present invention is used to feed the food according to the set recipe program during the cooking process of the cooking machine. It is located above the wok and can rotate 180 degrees when feeding, so that the food in the feeding device 1 falls into the wok in order due to its own gravity.

[0061] As shown in Figures 1 and 12, the unloading device 1 includes the aforementioned base frame 12 and the aforementioned compartment door 14. A guide groove is fixedly connected to the bottom of the base frame 12 for receiving a compartment box 4 containing ingredients. By controlling the opening and closing of the compartment door 14 mounted on the base frame 12, the unloading device 1 can unload ingredients according to a set recipe program during the cooking process. The aforementioned transmission assembly 3 and the aforementioned door lock clip 33 are mounted on the front and rear frames of the base frame 12. The compartment door 14 is provided with the aforementioned door lock patch 142. The corresponding drive component of the cooking machine can drive the transmission assembly 3 and the door lock clip 33 to disengage the door lock patch 142 in the aforementioned linear motion or rotational motion, thereby opening or closing the compartment door 14 in a sequence.
