[0025] As shown in Figs. 1-7, the size of the smart cooking machine of the present application is preferably in the range of 480-590mm x 560-600mm x 710-1400mm, and more preferably 480mm x 560mm x 710mm, 550mm x 600mm x 1400mm, 565mm x 600mm x 800mm or 590mm x 600mm x 800mm.

[0026] The cooking machine comprises a housing 200, a frame, a cooking cavity 1 installed on the frame, a frying pan device 100, a pan cover device (not shown in the figure) and a feeding device 110, wherein the cooking cavity 1 is arranged in the housing 200.

[0027] The structure of the cooking cavity 1 is preferably one of the following two structures:

[0028] 1) A feeding opening is formed on the top surface of the cooking cavity 1, and a feeding cavity 2 is arranged above the feeding opening and communicates with the feeding opening. The feeding cavity 2 is used to install the feeding device 110. The top of the feeding cavity 2 is provided with an inlet for the feeding device 110 to be installed in or removed from the feeding cavity 2. A top cover 120 is hingedly connected to the rear cross beam of the frame. When the top cover 120 is closed on the top of the cavity 2, the inlet is sealed. The top surface of the top cover 120 constitutes the top surface of the housing 200. The food materials contained in the feeding device 110 are fed into the frying pan of the frying pan device 100 arranged in the cooking cavity 1 below the feeding opening (at this time, the pan opening of the frying pan faces upward).

[0029] The front part of the cooking cavity 1 is open (with reference to the paper surface shown in Fig. 1, the direction pointing to the lower left is the front, the direction pointing to the upper right is the rear, and the same below). A machine door 130 is hingedly connected to the front vertical beam of the frame. The machine door 130 can close the opening. When the top cover 120 and the machine door 130 are both closed, the cooking cavity 1 and the feeding cavity 2 form a closed space. The feeding device 110, the frying pan device 100 and the pan cover device complete the corresponding cooking actions in the closed space.

[0030] 2) (not shown in the figure) The cooking cavity only has a front opening. The feeding device 110, the frying pan device 100 and the pan cover device are all installed in the cooking cavity. The feeding device 110 is installed above the cooking cavity. The frying pan device 100 is located below the feeding device 110. One or two machine doors are hingedly connected to the front vertical beam of the frame (when there are two machine doors, the two machine doors are arranged in an upper-lower manner. The upper machine door is used to close the opening area directly opposite the feeding device 110, and the lower machine door is used to close the remaining opening area). When the machine door is in a closed state, the cooking cavity becomes a closed space. The feeding device 110, the frying pan device 100 and the pan cover device complete the corresponding cooking actions in the closed space.

[0031] A water guide hole 4 is arranged in the middle of the bottom of the cooking cavity 1 to collect water flowing to the bottom of the cooking cavity 1 (for example, water after washing the wok is discharged to the outside of the cooking cavity 1 through the water guide hole 4 when the wok is cleaned).

[0032] The wok device 100 comprises, from outside to inside, a protective shell, a heating device arranged in the protective shell, and a wok. The heating device provides heat for the wok to heat food in the wok. A support shaft is arranged on the left side and the right side of the protective shell respectively. The protective shell is suspended on the corresponding side wall of the cooking cavity 1 through the support shaft. Under the drive of the support shaft, the protective shell carrying the wok and the heating device is turned to a preset station with the axis of the support shaft as the axis. The present application preferably comprises the following stations: a feeding station (the wok opening faces directly upward), a wok cleaning station (the wok opening faces the wok cleaning nozzle arranged on the rear wall of the cooking cavity 1), a cooking station (the wok opening faces the wok cover), and a dish outlet station (the wok opening faces the bottom of the cooking cavity 1). A driving device is arranged on the bottom of the wok. The driving device can drive the wok to rotate around the central axis of the wok.

[0033] The wok cover device is arranged on the rear wall of the cooking cavity 1. The wok cover can cover the wok opening to cooperate with the wok to cook dishes. For example, the seasoning device (not shown in the figure) of the wok machine sends the seasonings required by the dishes into the wok through the delivery pipe arranged on the wok cover. The smoke generated during the cooking of the wok is discharged into the oil fume treatment device through the exhaust pipe arranged on the wok cover for treatment.

[0034] When the wok machine starts the cooking work, the wok is placed at the feeding station. The food in the feeding device 110 is thrown downward into the wok. Then, the wok cooks the dishes under the cooperation of the wok cover. After that, the wok is turned to the dish outlet station. The dishes in the wok fall along the wok wall to the empty dish placed below the wok opening. Then, the wok cleaning program can be started as needed. Thus, the cooking task of a dish is completed. In this process, the components of the wok machine are distributed compactly, the division of labor is clear, and they cooperate with each other.

[0035] The main feature of the present application is that the space for cooking dishes and the space for cleaning tableware do not interfere with each other. Specifically as follows:

[0036] During the process of the wok from receiving food to dish outlet, the cooking cavity 1 is divided into an upper cavity and a lower cavity according to the position of the wok opening of the wok. When the wok is at the feeding station, the cooking station, and the wok cleaning station, the wok opening is in the upper cavity. The lower cavity is a space for the wok to turn to the dish outlet station and for the user to place the dish to receive the dishes in the wok. When the wok is turned downward to the dish outlet station, the wok opening is in the lower cavity.

[0037] When the frying pan is taken out and the opening of the frying pan is turned to the other working position, the lower cavity becomes an idle space. Based on this, the lower cavity is reused when it is idle based on the structure of the cooking cavity 1 and the layout of the components of the frying machine. Specifically, a quick insertion structure and a cleaning and drying device are added to the lower cavity. When the tableware needs to be cleaned, the basket 3 containing the tableware to be cleaned can be quickly installed on the quick insertion structure and placed in the lower cavity. The cleaning and drying device can clean and dry the tableware. Before the frying pan starts cooking again, the basket 3 is taken out of the lower cavity. Thus, the lower cavity becomes a space for the frying pan to take out the food after cooking. The frying machine has the functions of cooking and cleaning and drying tableware without interfering with each other, effectively improving the user experience and the space utilization of the lower cavity.

[0038] 1. Basket 3

[0039] As shown in FIGS. 1-4, the basket 3 is a hollow bracket having a recess for placing tableware. The recess is provided with a plurality of partitions for dividing the recess into a plurality of areas, so as to arrange different types of tableware, such as chopsticks, knives and forks, spoons and bowls, in corresponding areas for easy taking. Different sizes of bowls can be placed in the basket 3 without overlapping, so as to increase the spraying and drying range of the cleaning and drying device and improve the cleaning and drying efficiency.

[0040] 2. Quick insertion structure

[0041] As shown in FIGS. 1-4, the quick insertion structure is composed of a support table 11 and a roller 31.

[0042] The support table 11 is divided into left and right support tables which are the same in structure and symmetrically arranged. The left and right support tables 11 are preferably long strips extending from front to back and arranged on the left and right side walls at the bottom of the lower cavity. The horizontal distance between the left and right support tables 11 is greater than the maximum outer diameter of the frying pan. The left and right support tables 11 are used for positioning the roller 31 and serving as the moving track of the roller 31. The upper surface of the left and right support tables 11 is preferably a plane or an arc-shaped surface concave downward. The cross-sectional shape of the left and right support tables 11 is a rectangle or a right-angled trapezoid with a straight top edge, or a rectangle or a right-angled trapezoid with a downwardly concave circular arc top edge.

[0043] The plurality of rollers 31 are preferably fixedly installed on the left and right side walls of the basket 3, and the rollers 31 on the left and right side walls are symmetrically arranged, and the three rollers 31 on the same side wall are arranged in front and back intervals. The central axis holes of the rollers 31 are respectively connected with the installation shafts arranged on the corresponding left or right side wall, so that the rollers 31 are installed at positions below the middle lines of the left and right side walls. When the rollers 31 carry the basket 3 and are placed between the left and right support tables, the lower part of the basket 3 is below the top surface of the left and right support tables 11, so as to fully utilize the space occupied by the height of the left and right support tables, and there is a gap between the bottom of the basket 3 and the bottom panel 12 of the lower cavity.

[0044] When the rollers 31 carrying the basket 3 containing the dishes to be washed are rolled forward along the corresponding support table 11 to the position where the basket 3 is completely pushed into the lower cavity, the basket 3 is quickly and stably placed in the lower cavity. After the dishes are washed, the basket 3 can be easily taken out by pulling it forward and rolling the rollers 31 forward. The structure is simple and convenient to use.

[0045] 3. The cleaning and drying device

[0046] As shown in FIGS. 1-7, the cleaning and drying device comprises a plurality of nozzles arranged on the cavity wall of the cooking cavity and the bottom of the lower cavity, and a drying structure for drying the washed dishes.

[0051] The first nozzles 7 are used to spray clean water (referred to as clean water) downward to the basket 3 to wash the dishes. The number of the first nozzles 7 is preferably 2-4. When the number is 2, one first nozzle 7 is preferably arranged on the upper part of the left and right side walls of the lower cavity. When the number is 4, one first nozzle 7 is preferably arranged on the left and right side walls of the upper and lower cavities. The first nozzles 7 are preferably rotatable 360° in the plane of the corresponding side wall, so as to effectively increase the area of spraying clean water to the dishes, so that the dishes can be washed more comprehensively, and the cavity wall of the cooking cavity can also be washed at the same time.

[0052] When the first spray head 7 is opened, the water sprayed by the first spray head 7 flows into the water storage tank 6 (referred to as cleaning water) after spraying on the cavity wall of the cooking cavity 1 and the tableware, and the first spray head 7 supplies water to the water storage tank 6 in this way. The cleaning water can be directly discharged out of the cooking cavity 1 through the water outlet 67 on the water storage tank 6 according to the user's needs or recycled. The recycling mode is that the cleaning water is pressed to the spray arm 5 through the water outlet on the water storage tank 6, and is sprayed to the tableware in the basket 3 by the second spray head 8 to clean the tableware. Then, the cleaning water flows back into the water storage tank 6 again and can be discharged or recycled again according to the user's needs.

[0053] A plurality of second spray heads 8 are arranged in series on the spray arm 5, and the spray arm 5 is installed in the lower cavity and is located between the basket 3 and the bottom panel 12 of the lower cavity.

[0054] The spray arm 5 is long strip-shaped, which is composed of a supporting plate and a top cover sealingly connected to the supporting plate, and a water flow cavity is formed therebetween. A water inlet end extending downward and having an axial channel communicating with the water flow cavity is arranged in the middle region of the bottom surface of the supporting plate.

[0055] The structure of the water storage tank 6 of the present application is preferably the following two kinds, and the mounting mode of the spray arm 5 and the water storage tank 6 is specifically as follows:
