On the one hand, it is convenient for positioning and installing the unloading box assembly 40, and on the other hand, more interlayer space can be reserved between the casing 10 and the inner casing 13 for installing the seasoning device 20 and the oil fume treatment device 30.

[0044] 3. Positioning

[0045] A latch for receiving the blanking box assembly 40 is provided on the inner side wall of the lower portion of the rectangular body 132. The latch preferably has the following two structures:

[0046] 3.1. Angle bracket

[0047] As shown in FIG3 , the locking position is formed by corner brackets provided at the four corners (the included angles between two adjacent sides of the rectangular body 132 ) of the lower portion of the rectangular body 132 , and the four corners of the base frame are overlapped on the corner brackets.

[0048] The shape of the corner bracket can be determined according to the shape of the corners of the rectangular body 132. When the corners of the rectangular body 132 are right angles, the corner bracket is composed of a connecting plate and a supporting plate that are perpendicular to each other. The connecting plate is fixed to any one of the two adjacent sides at the corresponding angle. The supporting plate is in a horizontal state, and the supporting plates of the four corner brackets are all on the same horizontal plane.

[0049] Preferably, the corners of the rectangular body 132 are arc-shaped, and correspondingly, the four corners of the base frame are also arc-shaped. The connecting portion of the corner bracket is a curved plate that adapts to the arc-shaped corner, and the supporting portion of the corner bracket is a support plate that extends horizontally inward along the curved plate. By setting the corners of the rectangular body 132 to have the same arc-shaped corners as the corners of the base frame, the base frame can be directly positioned and installed in the blanking area, which is simple in structure and easy to operate.

[0050] Corner supports are provided at the four corners of the rectangular body 132. The supporting structure is stable and simple, and is not easy to harbor dirt.

[0051] Preferably, in order to facilitate the removal of the discharge box assembly 40 from the discharge area, space for the user to put his hand is reserved between the discharge box assembly 40 and the side wall of the rectangular body 132, and appropriate space is also reserved for the interaction between the door lock assembly 5 and the door opening mechanism 6 on the discharge box assembly 40. As shown in Figure 3, vertically distributed and arc-shaped positioning grooves 1 are provided at the four corners of the rectangular body 132. The back of the positioning groove is fixed to the rectangular body 132 by screws or glue. The corner bracket is a horizontal platform 2 extending horizontally inward along the bottom of the positioning groove 1. The four corners of the base frame are inserted along the corresponding positioning grooves 1 and rely on the horizontal platform 2.

[0052] The positioning groove 1 can limit the blanking box assembly 40 in the horizontal direction, so as to prevent the blanking box assembly 40 from shifting horizontally when the door opening mechanism or the door closing mechanism opens and closes the door panel of the blanking box assembly 40, resulting in inaccurate docking of the mechanism and causing blanking failure.

[0053] 3.2, Shelf 3

The connecting arm 711 is arranged parallel to the outer wall of the rectangular body 132. The toggle arm 712 extends inward along the other end of the connecting arm 711. Under the action of the door closing motor 7, the toggle arm 712 can push the corresponding warehouse door plate 4 8 resets upward (when the door plate 48 is pushed upward to contact the lock head 512 and gradually presses the lock head 512 and pushes the lock head 512 to the side opposite to the door plate 48, when the free end of the door plate 48 is higher than the lock hook platform of the lock head 512, the free end of the door plate 48 is separated from the lock head 512, and the lock head 512 quickly rebounds to the initial position under the action of the torsion spring, and the free end of the door plate 48 is locked on the lock hook platform, and the reset is completed); after the reset is completed, the door closing motor 7 rotates the toggle arm 712 to a position outside the door plate 48 to avoid affecting the opening of the door plate 48.

[0084] Preferably, the door closing mechanism resets the door plate 48 immediately after the corresponding compartment 4 is unloaded, so as to avoid the open door affecting the rotation of the wok 60 and prepare for the preparation of the next dish.

[0085] 7. Self-locking structure

[0086] A self-locking structure is provided inside or outside the material unloading area to prevent the material unloading box assembly 40 from being free to move vertically upward out of the locking position.

[0087] The self-locking structure of the present invention preferably has the following structures:

[0088] 7.1, Cover 70

[0089] As shown in Figures 1 and 2, the self-locking structure is a cover plate 70 covering the top surface of the casing 10; specifically, the rear side of the cover plate 70 is connected to the rear side of the top surface of the casing 10 through a hinge structure. When the cover plate 70 is covered on the top surface of the casing 10, the inner side surface of the cover plate 70 is pressed against the upper opening 41 of each compartment 4 of the blanking box assembly 40.

[0090] By providing a cover plate 70 to press the material box assembly 40 between the cover plate 70 and the latch, this prevents the entire material box assembly 40 from moving upward under the thrust of the door closing motor 7 when the door closing mechanism resets the compartment door plate 48, preventing the compartment door from properly resetting. The cover plate 70 acts as a self-locking mechanism and also prevents cooking fumes from escaping from the top opening 133 of the material discharge area during cooking, potentially polluting the external environment. Furthermore, the provision of the cover plate 70 enhances the overall aesthetics of the cooking machine.

[0091] 7.2 Hooking structure

[0092] As shown in Figure 9, the self-locking structure can also be composed of a hook arranged at the end of the toggle member 54 (the hook is composed of the vertical and horizontal parts of the toggle member 54) and a hook 621 at the end of the driving handle 62; when the driving handle 62 pushes the toggle member 54 to open the warehouse door on the corresponding side, the driving handle 62 returns to a certain distance and ensures that the hook and the hanger are in contact after the toggle member 54 returns to its original position, and then when the warehouse door is reset after the corresponding warehouse grid 4 is unloaded, the toggle member 54 is hooked by the driving handle 62 to prevent the entire unloading box assembly 40 from moving upward under the thrust of the door closing motor 7 and failing to reset the warehouse door normally.

[0093] By cleverly arranging a hook structure on the existing driving handle 62 and the toggle member 54, a self-locking function can be achieved while the overall structure is simple and the cost is low.

[0094] 7.3 Pin

[0095] The self-locking structure may also be composed of a pin provided on the side wall of the blanking area and a pin hole 77 provided on the base frame 43 .

[0096] The pin can be the iron core of the self-locking electromagnet installed on the outer wall of the rectangular body 132 (not shown in the figure). There are at least two pins, which are respectively arranged on opposite sides of the rectangular body 132. When the cooking machine control circuit receives the door reset signal, the door closing motor 7 and the self-locking electromagnet are turned on at the same time. After the self-locking electromagnet is energized, the iron core extends toward the base frame and is inserted into the pin hole 77 to lock the entire unloading mechanism to prevent displacement. This structural locking is more stable.

[0097] As shown in Figures 10 and 11, the pin can also be a linkage mechanism connected to the output shaft of the door closing motor 7, dividing the output shaft part placed outside the main body of the door closing motor 7 into a front section 72 and a rear section 73, the front section 72 is a screw structure, and the rear section 73 is a cylindrical structure; the linkage mechanism includes a transmission block 74 and a telescopic column 75 fixed to the transmission block 74.

[0098] The main body of the door closing motor 7 is arranged on the outer wall of the rectangular body 132 through a bracket 76, and the front section 72 of the output shaft is placed between the main body and the outer wall of the rectangular body 132. The rear section 73 passes through the outer wall of the rectangular body 132 and is placed in the unloading area and connected to the door closing dial 71. A positioning slide 78 parallel to the output shaft is also provided on the bracket 76. The transmission block 74 is simultaneously sleeved on the front section 72 and the positioning slide 78, and the transmission block 74 can make a linear motion along the positioning slide 78 under the transmission of the output shaft. The telescopic column 75 is fixed to the transmission block 74 in a manner parallel to the output shaft. A limiting hole 79 is provided on the side wall of the rectangular body 132, and one end of the telescopic column 75 is always placed in the limiting hole 79.

[0099] When the door plate 48 needs to be reset, the door closing motor 7 drives the output shaft and the door closing lever to rotate to push the door to reset upward. At the same time, the transmission block 74 drives the telescopic column 75 to extend forward under the action of the screw rod and insert it into the pin hole 77 to lock the blanking box assembly 40. The stroke of the telescopic column 75 moving to the pin hole 77 is shorter than the stroke of the door moving from the open state to contact with the lock head 512.

[0100] Preferably, the linkage mechanism is provided with two groups, which are respectively arranged on two door closing motors 7 at diagonally opposite corners.

[0101] This structure also cleverly utilizes existing electronic control components to achieve a self-locking function, which is low-cost and more intelligent.

[0102] Furthermore, as shown in FIG. 1 and FIG. 2 , the cooking machine of the present invention further includes a seasoning device 20 , an oil fume treatment device 30 and a human-machine control panel 80 .

[0103] Preferably, the seasoning device 20 is arranged at the upper front side of the casing 10 (that is, the seasoning device 20 is arranged in front of the front wall of the rectangular body 132 ), which fully utilizes the interlayer space between the front wall of the rectangular body 132 and the front side of the casing 10 .

[0104] The seasoning device 20 is used to automatically add liquid seasoning to the wok 60 according to the set cooking program during the cooking process. Specifically, the seasoning device 20 includes a frame, a plurality of seasoning bottles 21 and a plurality of seasoning pumps that are the same in number as the seasoning bottles 21. The plurality of seasoning bottles 21 are installed in the frame in a sequential arrangement from left to right, and can be quickly inserted from the front opening of the frame and connected to the seasoning pump fixed on the rear side of the frame, or quickly taken out from the front opening to add seasoning.

[0105] The human-machine control panel 80 is used by the user to control the cooking machine by selecting recipes, cleaning the cooking machine, etc., and is arranged on the top of the frame. Preferably, the human-machine control panel 80 is an embedded LCD touch screen, which is flush with the cover 70, making the overall appearance of the cooking machine neat and beautiful. At the same time, when the cooking machine is not working, the cover 70 can be used as a kitchen countertop, with high utilization rate.
