[0089] The present invention provides a cooking appliance, which may but is not limited to a stir-fry machine.

[0090] Figures 1 to 13 For an embodiment of the cooking appliance 100 provided by the present invention, please refer to Figure 1 The cooking appliance 100 includes a cooking main body 101, a pot lid assembly 102 and a controller. Generally speaking, the cooking appliance 100 also needs to heat food ingredients. Therefore, the cooking appliance 100 further includes a heating device 103. Obviously, in some embodiments, the cooking appliance 100 may not be provided with the heating device 103, and in this case, the cooking appliance 100 functions to make cold dishes. In the subsequent embodiments, the present invention will be described by taking the case where the heating device 103 is provided as an example.

[0091] The cooking main body 101 has a cavity with an open upper end. The pot lid assembly 102 is covered on the upper end of the cooking main body 101 to jointly enclose a cooking cavity with the cooking main body 101. Specifically, in the embodiment of the present invention, the cooking main body 101 includes a base 101a and an inner pot 101b. An accommodation cavity with an open upper end is formed inside the base 101a. The inner pot 101b is disposed in the accommodation cavity of the base 101a, and the inner pot 101b forms the cavity of the cooking main body 101. The pot lid assembly 102 and the inner pot 101b enclose a cooking cavity. Obviously, this design is not limited thereto. The cooking main body 101 may also adopt other structures. For example, the cooking main body 101 may be a heating platform plus a pot body placed on the heating platform. At this time, the inner cavity of the pot body forms the cavity of the cooking main body 101.

[0092] The pot lid assembly 102 is provided to cover the upper port of the cavity. The pot lid assembly 102 includes a pot lid main body 102a and a feeding device 102b. A material dropping port A is provided on the pot lid main body 102a. The feeding device 102b is arranged on the pot lid main body 102a, and the feeding port 11 (detailed introduction follows) of the feeding device 102b is arranged above the material dropping port A. The positional relationship between the feeding device 102b and the pot lid main body 102a is not limited. It can be that the feeding device 102b is arranged at the upper end of the pot lid main body 102a. In this case, the material dropping port A penetrates through the pot lid main body 102a. Or it can be that a pot lid cavity is formed inside the pot lid main body 102a, and the feeding device 102b is arranged in the pot lid cavity. In this case, the material dropping port A is arranged on the bottom wall of the pot lid cavity. Specifically, in the embodiment of the present invention, the feeding device 102b is arranged at the upper end of the pot lid main body 102a. Correspondingly, the material dropping port A penetrates through the pot lid main body 102a. In this way, it is convenient to separate the feeding device 102b from the pot lid main body 102a, and it is also convenient to put food materials and seasonings into the feeding device 102b.

[0093] The feeding device 102b includes a material tray 1, a blade assembly 2 and a driving mechanism 3. The material tray 1 includes a tray bottom, and a feeding port 11 is arranged on the tray bottom. The blade assembly 2 is rotatably arranged on the upper side of the tray bottom. The blade assembly 2 includes a plurality of blades 21. An accommodating cavity 12 is defined between two adjacent blades 21 on the upper side of the material tray 1. The driving mechanism 3 drives the blade assembly 2 to rotate so that each accommodating cavity 12 can be respectively placed above the feeding port 11.

[0094] In the technical solution provided by the present invention, the driving mechanism 3 can drive the blade assembly 2 to rotate. Therefore, the blade assembly 2 can successively rotate the accommodating cavity 12 defined between adjacent blades 21 above the feeding port 11. Cooking materials (such as food materials) can be directly arranged in the accommodating cavity 12, and cooking food materials (such as seasonings) can also be stored through a material box 5. In this way, sequential feeding of different cooking materials can be realized, so that food materials and seasonings can be added at different cooking stages, rather than adding food materials and seasonings into the cooking cavity at one time at the beginning of cooking. Obviously, for some common seasonings such as monosodium glutamate, salt, sugar, soy sauce, light soy sauce, five-spice powder, vinegar, etc., the adding order and time stage are different in different recipes. Only in this way can delicious dishes be cooked.

[0095] The heating device 103 is used to heat the cooking cavity. Generally speaking, the heating device 103 is arranged in the cooking main body 101. Specifically, in the embodiment of the present invention, the heating device 103 is arranged on the base 101a. The heating device 103 can be an electromagnetic heating device 103, a hot plate heating device 103, an infrared heating device 103, etc., without limitation. Specifically, in the embodiment of the present invention, the heating device 103 is an electromagnetic heating device 103.

[0096] The controller is electrically connected to the driving mechanism 3 (which can be a wired connection or a wireless connection) to control the operation of the driving mechanism 3. Further, in this embodiment, since the cooking appliance 100 further includes a heating device 103, the controller is also electrically connected to the heating device 103 to control the operation of the heating device 103.

[0097] The controller can be arranged in the cooking main body 101 or in the lid assembly 102. Of course, the controller can also include multiple control devices, and the multiple control devices are separately arranged in the cooking main body 101 and the lid assembly 102. That is to say, the controller is the general term for the control system and is not limited to a single control device.

[0098] In this embodiment, the material tray 1 further includes a side portion. The side portion of the material tray 1 extends upward from the bottom of the material tray 1. Obviously, this design is not limited thereto. The material tray 1 can also be without a side portion and only have a bottom. Of course, in some embodiments, a cover can also be provided on the material tray 1 to cover the material tray 1.

[0099] The multiple blades 21 form multiple accommodation cavities 12 on the material tray 1. The multiple blades 21 can also be evenly distributed, so the sizes and shapes of the corresponding multiple accommodation cavities 12 are the same. The multiple blades 21 can also be unevenly distributed, then the sizes and shapes of the corresponding multiple accommodation cavities 12 are not the same. Specifically, in this embodiment, the multiple blades 21 are evenly distributed, that is, the sizes and shapes of the multiple accommodation cavities 12 are the same.

[0100] In this embodiment, the blade assembly 2 further includes a mounting portion 22. The mounting portion 22 is rotatably arranged along the vertical axis. The specific rotation mounting position of the mounting portion 22 depends on the actual situation. It can be rotatably mounted on the material tray 1 or on a component outside the material tray 1. For example, a cover is provided on the upper side of the material tray 1, and the mounting portion 22 is rotatably mounted on the cover. The multiple blades 21 extend from the mounting portion 22 toward the circumferential side of the bottom of the material tray 1.

[0101] The driving mechanism 3 drives the blade assembly 2 to rotate. The driving mechanism 3 can be driven by a motor + transmission mechanism, or directly driven by a motor. It can also be that the driving mechanism 3 adopts magnetic drive, etc. That is, the specific structure of the driving mechanism 3 is not limited in the present invention.

[0102] In this embodiment, the feeding port 11 is adapted in size and shape to at least part of the bottom of the accommodating cavity 12, so that when the corresponding accommodating cavity 12 corresponds to the feeding port 11, the bottom of the accommodating cavity 12 is provided with a hollow, so that the food materials in the cavity can all slide down from the feeding port 11. Specifically, in the embodiment of the present invention, the shapes and structures of the plurality of accommodating cavities 12 are the same. Therefore, the feeding port 11 is adapted in shape and size to the bottoms of the respective accommodating cavities 12.

[0103] When the blade assembly 2 rotates, the accommodating cavity 12 rotates to the feeding port 11. Because the feeding port 11 is adapted in size and shape to the bottom of the accommodating cavity 12, the bottom of the accommodating cavity 12 is hollow, so that the food materials or seasonings in the accommodating cavity 12 will all fall from the feeding port 11, so as to avoid incomplete falling of the food materials or seasonings in the accommodating cavity 12 and leaving food materials on the material tray 1.

[0104] When the blade assembly 2 rotates, one feeding is completed for each rotation, that is, it is ensured that one accommodating cavity 12 is directly opposite to the feeding port 11 for each rotation. Therefore, in the embodiment of the present invention, the feeding device 102b further includes a rotation angle detection device 4, and the rotation angle detection device 4 is used to detect the rotation angle of the blade assembly 2, so that after the blade assembly 2 completes the rotation, the corresponding accommodating cavity 12 can be directly opposite to the feeding port 11, so that after the blade assembly 2 completes one rotation, the corresponding accommodating cavity 12 can be directly opposite to the feeding port 11, thus avoiding incomplete throwing of the food materials or seasonings through the feeding port 11 due to misalignment between the accommodating cavity 12 and the feeding port 11 after rotation.

[0105] The structure for realizing the rotation angle detection device 4 can be a travel switch or an angle positioning structure. Specifically, in the embodiment of the present invention, as Figures 12 to 13, the rotation angle detection device 4 includes a grating 41 and an optocoupler 42. The grating 41 is coaxially arranged with the blade assembly 2 and rotates together with the blade assembly 2. The grating 41 has a cylindrical grating side portion 411, and a plurality of slotted openings 412 are provided on the grating side portion 411. The positions of the plurality of slotted openings 412 correspond to the positions of the plurality of blades 21. The optocoupler 42 includes a transmitting portion 421 and a receiving portion 422 which are oppositely arranged. The transmitting portion 421 and the receiving portion 422 are respectively arranged on both sides of the grating side portion 411. The optocoupler 42 and the driving mechanism 3 are electrically connected to the controller of the cooking machine, so that every time the blade assembly 2 rotates, the controller of the cooking machine controls the driving mechanism 3 to stop driving the blade assembly 2 to rotate according to the signal of the receiving portion 422, so that after the blade assembly 2 completes one rotation, the corresponding accommodating cavities 12 can be set to face the feeding port 11 exactly.

[0106] In the embodiment of the present invention, the rotation angle of the driving mechanism 3 is controlled by the grating 41 and the optocoupler 42. For this purpose, the driving mechanism 3 can adopt an ordinary motor, and it is not necessarily required to be provided with a stepping motor with a higher control accuracy, etc., so that the cost can be saved. Of course, in some embodiments, the driving mechanism 3 includes a stepping motor, and the stepping motor is controlled to rotate according to a set number of steps, so that after the blade assembly 2 completes the rotation, the corresponding accommodating cavities 12 can be set to face the feeding port 11 exactly.

[0107] Some of the plurality of accommodating cavities 12 can be used to store ingredients, or all of them can be used to store ingredients. For example Figures 18 to 19 As shown, in other embodiments of the present invention, some of the plurality of accommodating cavities 12 are used to accommodate ingredients. The feeding device 102b further includes a material box 5 and a seasoning driving assembly 6. The material box 5 is installed in the other part of the accommodating cavities 12 and is driven to rotate by the blade assembly 2. The material box 5 is used to store seasonings (the seasonings are granular solids or the seasonings are liquids). The seasoning driving assembly 6 is used to drive the material box 5 to open and discharge materials when the accommodating cavity 12 where the material box 5 is located is above the feeding port 11. In this way, the ingredients can be fed successively, and the seasonings can be fed successively. Furthermore, the ingredients and seasonings can be added at different stages according to different dishes, so as to stir-fry and add seasonings in different stages respectively, making the taste of the finally cooked dishes better.

[0108] The seasonings can be granular solid seasonings or liquid seasonings. For example, the solid seasonings include but are not limited to monosodium glutamate, table salt, sugar, five-spice powder, etc., and the liquid seasonings can include but are not limited to soy sauce, light soy sauce, vinegar, etc.

[0109] In this embodiment, the food ingredients are directly placed in a part of the accommodating cavity 12 and are fed by directly being stirred by the blades 21. The seasonings are arranged in the seasoning box 5, and the seasoning box 5 is placed in another part of the accommodating cavity 12. The seasoning box 5 is also stirred by the blades 21 and is automatically fed by being driven by the seasoning driving assembly 6. Therefore, since no additional structure is required to accommodate the food ingredients, the structure of the feeding device 102b is relatively simple. Moreover, since the seasonings are generally granular or liquid, they are placed in the seasoning box 5 to feed through the seasoning box 5, and will not adhere to or remain on the material tray 1 to cause flavor mixing or make the material tray 1 difficult to clean.

[0110] When the cooking appliance 100 provided by the embodiment of the present invention is working, it mainly includes the following processes:

[0111] First, the user places the food ingredients corresponding to the recipe in a part of the accommodating cavity 12, places the seasonings corresponding to the recipe in the seasoning box 5, and places the seasoning box 5 in another part of the accommodating cavity 12;

[0112] Next, when the controller receives a working instruction, it controls the driving mechanism 3 to work so that the blade assembly 2 rotates;

[0113] Next, the rotation angle detection device 4 detects the rotation angle of the blade assembly 2 and transmits the detection signal to the controller. Specifically, when the driving mechanism 3 rotates the accommodating cavity 12 where the food ingredients are located to the position where the feeding port 11 is located for feeding, and rotates the accommodating cavity 12 where the seasoning box 5 is located to the position where the feeding port 11 is located, and then controls the feeding driving mechanism 3 to drive the seasoning box 5 to dispense seasonings.

[0114] There is no limitation on the specific position where the seasoning driving assembly 6 is arranged. Specifically, in the embodiment of the present invention, a part of the bottom of the material tray 1 protrudes upward to form an installation groove 13 on the outer side of the bottom of the seasoning box 5. A through hole 14 is provided on the side wall of the installation groove 13 at a position corresponding to the feeding port 11. The driving mechanism 3 and the seasoning driving assembly 6 are arranged in the installation groove 13, and the seasoning driving assembly 6 is arranged corresponding to the through hole 14.

[0115] In an embodiment of the present invention, the seasoning box 5 includes a first seasoning box 51 and / or a second seasoning box 5, that is, the seasoning box 5 may only include the first seasoning box 51, may also only include the second seasoning box 5, or may include both the first seasoning box 51 and the second seasoning box 5.
