[0034] Figure 1 is a three - dimensional structural schematic diagram of a cooking appliance shown in some embodiments of this specification; Figure 2 is a three - dimensional structural schematic diagram of the side - rear view angle of a cooking appliance shown in some embodiments of this specification; Figure 3 is a schematic diagram of the open state of the smoke collecting hood shown in some embodiments of this specification; Figure 4 is a side - rear view angle schematic diagram of the open state of the smoke collecting hood shown in some embodiments of this specification; Figure 5 is a schematic diagram of the inclined state of the rotating cooking body shown in some embodiments of this specification. As Figures 1-5As shown, some embodiments of this specification provide a cooking appliance 100, which includes a base 110, a rotating cooking body 120, and a smoke collecting device 130. The rotating cooking body 120 is rotatably arranged on the base 110. The rotating cooking body 120 can carry a cooking pot 150 and drive the cooking pot 150 to rotate relative to the base 110. In some embodiments, the rotating cooking body 120 and the cooking pot 150 are of an integral structure; alternatively, the cooking pot 150 is detachably installed on or placed on the rotating cooking body 120. In some embodiments, bearings are provided on the base 110, and the rotating cooking body 120 is rotatably arranged on the base 110 by means of a rotating shaft cooperating with the bearings. In some embodiments, the cooking appliance 100 may include a controller 160, and the controller 160 can be used to control the rotation of the rotating cooking body 120 relative to the base 100.

[0035] In some embodiments, the rotating cooking body 120 can rotate to a first state or a second state; when the rotating cooking body 120 is in the first state, the included angle between the upper surface of the cooking pot 150 and the horizontal plane is less than 30 degrees; when the rotating cooking body 120 is in the second state, the included angle between the upper surface of the cooking pot 150 and the horizontal plane is greater than 30 degrees. As Figure 1 shown in FIG. 3, the rotating cooking body 120 is in the first state, at this time the upper surface of the cooking pot 150 is parallel or approximately parallel to the horizontal plane; when the rotating cooking body 120 is in the first state, the cooking pot can be used for stir-frying, serving dishes, etc. As Figure 5 shown, the rotating cooking body 120 is in the second state (tilted state), at this time the upper surface of the cooking pot 150 has a relatively large inclination angle with respect to the horizontal plane; when the rotating cooking body 120 is in the second state, it is very convenient to pour out the dishes, liquids, etc. in the cooking pot. By setting the rotating cooking body 120 to be rotatable to the first state or the second state, it is possible to facilitate serving dishes and cleaning the cooking pot on the basis of ensuring the normal stir-frying function of the cooking pot. For example, when it is necessary to serve dishes, the rotating cooking body 120 can be rotated to the second state and a vegetable basin can be placed under the cooking pot, so as to pour the dishes in the cooking pot into the vegetable basin. Another example is that when it is necessary to clean the cooking pot, the rotating cooking body 120 can be rotated to the second state to pour out the water for cleaning the cooking pot.

[0036] In some embodiments, when the rotating cooking body 120 is in the second state, at least part of the edge of the cooking pot 150 is lower than the center of the inner surface of the cooking pot. Specifically, when the rotating cooking body 120 is in the second state, the serving edge (i.e., the edge area for serving dishes) of the cooking pot 150 can be lower than the center of the inner surface of the cooking pot, so that serving dishes (or pouring water) is more convenient and thorough.

[0037] Figure 6 is a schematic diagram of the rotating cooking body without carrying a cooking pot according to some embodiments of this specification; Figure 7It is a schematic internal structure diagram of a rotating cooker body shown in some embodiments of this specification. Combining Figures 6-7 As shown, in some embodiments, a first smoke guide channel 121 and a combustion chamber 123 are provided in the rotating cooker body 120, and one end of the first smoke guide channel 121 is communicated with the combustion chamber 123. The combustion chamber 123 can be a space in the cooker 100 that accommodates the combustion flame, and it can be formed by enclosing with a flame baffle. In some embodiments, a burner 124 can be provided inside the combustion chamber 123 (such as at the bottom of the combustion chamber 123), and the burner 124 can be used to generate a flame. In some embodiments, the opening of one end of the first smoke guide channel 121 can be arranged inside the combustion chamber 123, so that one end of the first smoke guide channel 121 is communicated with the combustion chamber 123. Further, the opening of one end of the first smoke guide channel 121 can be arranged near the burner 124, so that the air, oil fume, etc. coming out of the first smoke guide channel 121 lead to the burner 124.

[0038] In some embodiments, such as Figures 1-5 As shown, the smoke collecting device 130 can include a smoke collecting hood 131 and a smoke collecting pipe cavity 132. When the rotating cooker body 120 is in the first state (such as the state shown in Figure 1 ), the smoke collecting hood 131 can move and stop above the cookware 150, and at this time, the smoke collecting pipe cavity 132 is communicated with the other end of the first smoke guide channel 121, and the oil fume in the cookware 150 can be transported to the combustion chamber 123 through the smoke collecting pipe cavity 132 and the first smoke guide channel 121. In some embodiments, the communication between the smoke collecting pipe cavity 132 and the other end of the first smoke guide channel 121 can be: the smoke collecting pipe cavity 132 is directly communicated with the other end of the first smoke guide channel 121, or the smoke collecting pipe cavity 132 is communicated with the other end of the first smoke guide channel 121 through other channels (such as a second smoke guide channel 141).

[0039] In some embodiments, such as Figures 6-7 As shown, a first waste hot air channel 122 can also be provided in the rotating cooker body 120, and one end of the first waste hot air channel 122 is communicated with the combustion chamber 123. In some embodiments, the opening of one end of the first waste hot air channel 122 can be arranged inside the combustion chamber 123, so that one end of the first waste hot air channel 122 is communicated with the combustion chamber 123. By communicating one end of the first waste hot air channel 122 with the combustion chamber 123, the waste hot air in the combustion chamber 123 can be led out through the first waste hot air channel 122.

[0040] Figure 8 It is a schematic structure diagram of a heat exchanger shown in some embodiments of this specification; Figure 9 It is a schematic internal structure diagram of a heat exchanger shown in some embodiments of this specification. In some embodiments, such as Figures 1-5 and Figures 8-9As shown, the cooking appliance 100 further includes a heat exchanger 140, and a second smoke guide channel 141 and a second waste hot gas channel 142 are provided in the heat exchanger 140. In some embodiments, when the rotating cooker body 120 is in the first state, the other end of the first smoke guide channel 121 communicates with one end of the second smoke guide channel 141, and the other end of the first waste hot gas channel 122 communicates with one end of the second waste hot gas channel 142; when the rotating cooker body 120 is in the first state and the smoke collecting hood 131 stops above the cookware 150, the smoke collecting pipe cavity 132 is docked (communicated) with the other end of the second smoke guide channel 141, so that the smoke collecting pipe cavity 132 is docked (communicated) with the other end of the first smoke guide channel 121 through the second smoke guide channel 141. In some embodiments, the docking can be a sealed docking or an unsealed docking; through the negative pressure effect of the fan, even an unsealed docking can effectively prevent the escape of oil fumes. In some embodiments, when the cooking appliance is used for stir-frying, the rotating cooker body 120 is in the first state, the smoke collecting hood 131 stops above the cookware 150, the smoke collecting hood 131 can collect the oil fumes generated during stir-frying, and the oil fumes are led out from the smoke collecting pipe cavity 132 and are conveyed to the combustion chamber 123 via the second smoke guide channel 141 and the first smoke guide channel 121. The oil fumes can be used as fuel, thereby achieving energy conservation and improving the combustion effect.

[0041] In some embodiments, the second smoke guide channel 141 and the second waste hot gas channel 142 perform heat exchange in the heat exchanger 140. In some embodiments, the heat exchanger 140 can be a plate heat exchanger, a tube heat exchanger, or the like. In some embodiments, as Figure 9 shown, the heat exchanger 140 is a plate heat exchanger, the second smoke guide channel 141 and the second waste hot gas channel 142 are respectively arranged on both sides of the heat exchange plate. Fresh air and oil fumes can be conveyed in the second smoke guide channel 141, and waste hot gas can be conveyed in the second waste hot gas channel 142; through the heat exchange plate, the heat of the waste hot gas can be transmitted to the fresh air and the oil fumes, so that the fresh air and the oil fumes conveyed to the combustion chamber 123 have a relatively high temperature, promoting the combustion of the burner 124 and further achieving energy conservation and improving the combustion effect.

[0042] In some embodiments, as Figures 1-5 shown, the smoke collecting hood 131 is rotatably arranged on the base 110. When the rotating cooker body 120 is in the first state, the smoke collecting hood 131 can rotate and stop above the cookware 150; the smoke collecting hood 131 can rotate and open relative to the cookware 150. When the smoke collecting hood 131 is in the open state (such as the state shown in Figures 3-5 ), the smoke collecting hood 131 and the smoke collecting pipe cavity 132 are separated from the rotation space of the rotating cooker body 120. The rotation space of the rotating cooker body 120 can be understood as the space that the rotating cooker body 120 may occupy during rotation. In some alternative embodiments, the smoke collecting hood 131 can be arranged on the base 110 by other movement modes. For example, the smoke collecting hood 131 is movably arranged on the base 110.

[0043] In some embodiments, the smoke collecting pipe cavity 132 may be a rigid pipe. One end of the smoke collecting pipe cavity 132 is communicated with the smoke collecting hood 131, and the size of the other end of the smoke collecting pipe cavity 132 is not greater than that of the other end of the second smoke guiding cavity 141. By setting the size of the other end of the smoke collecting pipe cavity 132 to be not greater than that of the other end of the second smoke guiding cavity 141, the smoke collecting pipe cavity 132 and the second smoke guiding cavity 141 can be conveniently matched, effectively reducing the escape of oil fume. By setting the smoke collecting pipe cavity 132 as a rigid pipe, it is beneficial for the smoke collecting pipe cavity 132 to move to the set position each time to communicate with the smoke collecting hood 131, and at the same time helps to extend the service life of the smoke collecting pipe cavity 132. In some embodiments, the other end of the second smoke guiding cavity 141 is in a flared or inverted cone-like shape (not shown in the figure). By setting the other end of the second smoke guiding cavity 141 to be in a flared or inverted cone-like shape, the other end of the smoke collecting pipe cavity 132 can be more easily communicated with the second smoke guiding cavity 141.

[0044] In some embodiments, the cooking appliance 100 further includes a blower 143, and the air outlet of the blower is docked with the second smoke guiding cavity 141. In some embodiments, the turbine of the blower 143 (not shown in the figure) may be disposed in the second smoke guiding cavity 141 or docked with the second smoke guiding cavity 141. By providing the blower, the oil fume can be effectively guided, so as to convey the oil fume to the combustion chamber 123; moreover, the blower can form a negative pressure at the other end of the second smoke guiding cavity 141, thereby preventing the oil fume in the smoke collecting pipe cavity 132 from escaping. In some embodiments, an air inlet (such as an air grid) may be provided at the turbine of the blower 143, so that the blower can convey fresh air while conveying the oil fume, providing sufficient oxygen for the combustion of the fuel. In some embodiments, as Figure 9 shown, the blower 143 is disposed near the inlet of the other end of the second smoke guiding cavity 141, and the blower 143 can convey fresh air and / or oil fume to the heat exchanger 140. The moving path of the fresh air and / or oil fume after entering the heat exchanger can be seen as shown by the arrow A in Figure 9 . After the fresh air and / or oil fume are sufficiently heat-exchanged, they are output from one end of the second smoke guiding cavity 141 and enter the first smoke guiding cavity 121, and then are conveyed to the burner. In some embodiments, as Figure 9 shown, the waste hot air entering the second waste hot air cavity 142 can move upward along the direction shown by the arrow B in the figure and be discharged from the other end of the second waste hot air cavity 142 (such as the exhaust port at the top in the figure).

[0045] In some embodiments, the smoke collecting pipe cavity 132 can be a flexible pipe, and the smoke collecting pipe cavity 132 remains in communication with the other end of the second smoke guiding cavity 141. For example, the smoke collecting pipe cavity 132 can be a telescopic flexible pipe (such as a smoke guiding pipe). By keeping the smoke collecting pipe cavity 132 in communication with the other end of the second smoke guiding cavity 141, the situation where the smoke collecting pipe cavity 132 is misaligned with the second smoke guiding cavity 141 can be avoided, and at the same time, the escape of oil fume can be effectively reduced.

[0046] In some embodiments, such as Figures 1-4 shown, the smoke collecting hood 131 can be rotatably arranged on the base 110 through a rocker arm 133. One end of the rocker arm 133 is connected to the upper part of the smoke collecting hood 131, and the other end of the rocker arm 133 is rotatably connected to the base 110. In some embodiments, a stir-frying device 170 is provided inside the smoke collecting hood 131, and one end of the stir-frying device 170 is rotatably connected to the upper part of the smoke collecting hood 131. By providing the stir-frying device 170, automatic stir-frying can be achieved when the smoke collecting hood 131 is closed. In some embodiments, a stir-frying driving motor is provided on the upper part of the smoke collecting hood 131, and the stir-frying driving motor can drive the stir-frying device 170 to rotate. In some embodiments, the signal line and power line of the stir-frying driving motor can be connected to the controller 160 and the power supply via the rocker arm 133. In some embodiments, the stir-frying driving motor can also be arranged in the base 110 and drive the stir-frying device 170 to rotate through a transmission mechanism. In some embodiments, the smoke collecting hood can also be docked above the pot opening and the other end of the blower or the second smoke guiding cavity by moving up and down or rotating and translating.

[0047] In some embodiments, such as Figure 3 and Figure 5 shown, a guiding plate 125 can be provided on the rotating cooker body 120. One side of the guiding plate 125 is attached to the serving edge of the cooking utensil 150, and the other side of the guiding plate 125 is suspended. In some embodiments, blocking plates 1251 are provided at both ends of the guiding plate 125. The blocking plates 1251 can be fixedly connected to both ends of the guiding plate 125 or integrally formed with the guiding plate 125. By providing the guiding plate 125, the dishes can be guided during serving, thus facilitating the pouring of the dishes.

[0048] In some embodiments, such as Figure 1 shown, a feeding port 1311 can be provided on the smoke collecting hood 131. By providing the feeding port 1311, feeding can be carried out during automatic stir-frying. In some embodiments, the feeding port 1311 is in a quasi-elliptical or quasi-square shape. The quasi-elliptical or quasi-square feeding port is convenient for processing and not easy to scratch the hand. In some embodiments, the feeding port can be in other shapes. For example, the feeding port can be a combined shape of a quasi-elliptical or quasi-square shape, a square, a circle, etc.

[0049] In some embodiments, an opening and closing mechanism (not shown in the figure) may be provided on the feeding port 1311. The opening and closing mechanism can close the feeding port or open relative to the feeding port. For example, the opening and closing mechanism may be in the shape of a plate and rotatably connected to the smoke collecting hood 131. The shape of the opening and closing mechanism and the feeding port may be the same or similar. By providing the opening and closing mechanism, the feeding port 1311 can be conveniently opened for feeding when feeding is required, and the feeding port 1311 can be closed when feeding is not required to avoid heat loss and oil fume escape.
