[0039] See also Figure 1 , Figure 1 A structural schematic diagram of a cooking device 100 in an embodiment of the present application is shown. The cooking device 100 provided in an embodiment of the present application may be an oven, a steam oven, or any device with a cooking function, without limitation.
[0040] Combination Figure 2 As shown, Figure 2 FIG. 1 shows a schematic diagram of the exploded structure of a cooking device 100 in an embodiment of the present application. The cooking device 100 includes an inner pot 110, wherein the inner pot 110 is provided with a cooking cavity 111, and the cooking cavity 111 is used to cook food. Figure 1 As shown, the inner pot 110 includes a top plate 112 for defining the top of the cooking cavity 111. The top plate 112 is provided with a plurality of air inlet holes 1121 connected to the cooking cavity 111, and the air inlet holes 1121 are distributed in an array. The air inlet holes 1121 are distributed in an array, so that the airflow injected into the cooking cavity 111 can enter the cooking cavity 111 through the air inlet holes 1121 at different positions, and the high-speed injected airflow breaks the original airflow stratification phenomenon at different positions, enhances the mixing and diffusion of the air, and thus achieves a uniform heating effect on different positions of the cooking cavity 111.
[0041] It is understandable that the higher the proportion of the distribution area of the air inlet holes 1121 to the total area of the top plate 112, the wider the airflow injected into the cooking cavity 111 covers the entire cooking cavity 111, and will not be overly concentrated in a certain area. In this embodiment, the distribution area of the air inlet holes 1121 is not less than half of the total area of the top plate 112.
[0042] like Figure 2 As shown, in one embodiment, the air inlet holes 1121 are radially distributed on the top plate 112 from the center to the outside of the top plate 112. Specifically, the air inlet holes 1121 are distributed along the same radial direction to form an air hole string, and multiple air hole strings are distributed along the circumferential direction, and the angles between adjacent air hole strings are equal. The number of air inlet holes 1121 in each air hole string is the same, and the corresponding air inlet holes 1121 of different air hole strings are equidistantly distributed along the circumferential direction. In other embodiments, the arrangement of the air inlet holes 1121 can also be based on other arrays, such as a rectangular array, an annular array, etc., without limitation.
[0043] like Figure 1 As shown, the cooking device 100 further includes an upper heating tube 140, which is used to provide heat to the cooking cavity 111 for cooking food. Figure 1 As shown, the upper heating tube 140 is located inside the cooking cavity 111 and at the top of the cooking cavity 111, the top plate 112 with the air inlet hole 1121 is located above the upper heating tube 140, and the distribution range of the air inlet hole 1121 is located above the upper heating tube 140, so that the airflow ejected from the air inlet hole 1121 can enter the cooking cavity 111 and flow through the vicinity of the upper heating tube 140, and drive the airflow near the upper heating tube 140 to flow fully, thereby achieving enhanced air mixing and diffusion, thereby achieving a uniform heating effect on different positions of the cooking cavity 111.
[0044] like Figure 1 and Figure 2 As shown, the cooking device 100 further includes an air intake assembly 120, the air intake assembly 120 includes a jet element 121 for ejecting airflow, the jet element 121 is used to eject cold airflow or hot airflow, the jet element 121 can be selectively connected to each air intake hole 1121, under different working requirements, the air intake assembly 120 switches to different working modes, the air intake assembly 120 can selectively connect to a specific air intake hole 1121 to eject airflow toward the cooking cavity 111, so that the airflow ejected by the jet element 121 can enter the cooking cavity 111 through the air intake hole 1121, so as to break the original airflow stratification phenomenon inside the cooking cavity 111, enhance the mixing and diffusion of air in the cooking cavity 111, thereby reducing the temperature difference inside the cooking cavity 111, and achieving a uniform heating effect inside the cooking cavity 111. In some embodiments, the jet element 121 can be selectively connected to each air intake hole 1121 by setting a switchable structure in the channel connected to each air intake hole 1121.
[0045] Combination Figure 3 and Figure 4 As shown, in one embodiment, the air intake assembly 120 includes a spray box 122 located on the top of the inner container 110, such as Figure 3 As shown, the injection box 122 includes a accommodating cavity 1221 which is connected to the injection member 121, and the injection box 122 includes a bottom plate 1222 with a first air outlet 1223 at the bottom, the bottom plate 1222 is attached to the top plate 112, the first air outlet 1223 and the air inlet 1121 are arranged in a one-to-one correspondence, so that after the cold airflow or hot airflow in the injection member 121 enters the accommodating cavity 1221, it passes through the first air outlet 1223 and the air inlet 1121 in sequence and then enters the cooking cavity 111, and the aperture of the air inlet 1121 is not less than the aperture of the first air outlet 1223, so as to avoid interference with the flow of the airflow ejected by the injection member 121.
[0046] Combination Figure 5 and Figure 6 In one embodiment, the air intake assembly 120 further includes a first baffle 123 rotatably connected to the injection box 122 and located inside the accommodating cavity 1221, wherein the first baffle 123 is provided with a first avoidance opening 1231. When the first baffle 123 is attached to the bottom plate 1222, the first air outlet 1223 located at the first avoidance opening 1231 communicates with the accommodating cavity 1221 and the cooking cavity 111. At this time, the airflow in the accommodating cavity 1221 can only enter the cooking cavity 111 through the first air outlet 1223 located at the first avoidance opening 1231, so that the accommodating cavity 1221 can pass through a specific (i.e., the first avoidance opening 1231) air outlet of the first baffle 123. 231) is connected to the cooking cavity 111, so that the jet element 121 is connected to the cooking cavity 111 through the specific first air outlet 1223, so that the airflow ejected by the jet element 121 is only ejected into the cooking cavity 111 at the specific air outlet, so that the cold airflow or hot airflow is introduced into the air inlet 1121 at the specific position of the cooking cavity 111 (i.e., the first avoidance port 1231), thereby breaking the original airflow stratification phenomenon at the specific position, enhancing the mixing and diffusion of the air, and achieving a uniform heating effect at the specific position of the cooking cavity 111, which is suitable for the case where the heating degree needs to be increased or decreased at the specific position of the food during the cooking process. In this embodiment, the first baffle 123 can move relative to the bottom plate 1222, and there is a position in the moving path of the first baffle 123. When the first baffle 123 is at this position, the first baffle 123 is in contact with the bottom plate 1222.
[0047] like Figures 4 to 7 As shown, in one embodiment, the air intake assembly 120 also includes a driving member 1241 and a transmission shaft 1242, wherein the transmission shaft 1242 is transmission-connected to the driving member 1241, and one end of the transmission shaft 1242 away from the driving member 1241 is connected to the first baffle 123 to drive the first baffle 123 to rotate. In this embodiment, the first baffle 123 and the spray box 122 are both circular structures, and the two are concentrically arranged. In other embodiments, the structures of the first baffle 123 and the spray box 122 can also be other structures, but the rotation axis of the first baffle 123 preferably corresponds to the central axis of the distribution area of the first air outlet 1223, and the rotation area of the first baffle 123 covers the distribution area of the first air outlet 1223, so that the first baffle 123 can cover and block any first air outlet 1223.
[0048] like Fig.10 As shown, in one embodiment, the driving member 1241 can also drive the transmission shaft 1242 to move in the axial direction of the transmission shaft 1242, such as Figure 3 As shown, the first baffle 123 is close to the bottom plate 1222, or as shown Figure 6and Fig.10 As shown, the first baffle 123 is away from the bottom plate 1222. When the first baffle 123 is attached to the bottom plate 1222, the first baffle 123 covers part of the first air outlet holes 1223. When the first baffle 123 is away from the bottom plate 1222, each first air outlet hole 1223 is connected to the accommodating cavity 1221 and the cooking cavity 111. At this time, each air outlet hole can spray air toward the cooking cavity 111.
[0049] like Figures 5 to 7 As shown, in one embodiment, the air intake assembly 120 further includes a partition 125 connected to the injection box 122 and located inside the accommodating cavity 1221, as shown in FIG. Figure 6 and Fig.10 As shown, the partition 125 divides the accommodating cavity 1221 into a first cavity 1252 and a second cavity 1253, and the partition 125 is provided with a second air outlet 1251 to connect the first cavity 1252 and the second cavity 1253, the jet element 121 can be selectively connected to the second cavity 1253, and the first air outlet 1223 connects the first cavity 1252 and the cooking cavity 111. Figure 3 and Figure 4 As shown, the jet element 121 is connected to the second cavity 1253 through the connecting pipe 129. Optionally, the connecting pipe 129 can be opened and closed, for example, a valve body for controlling the opening and closing of the connecting channel is set in the connecting pipe 129, so that the jet element 121 can be selectively connected to the second cavity 1253. In one of the working requirements of the air intake assembly 120, the cold air flow or hot air flow ejected by the jet element 121 can enter the second cavity 1253 through the connecting pipe 129, then enter the first cavity 1252 through the second air outlet 1251, and then enter the cooking cavity 111 through the first air outlet 1223 and the air intake 1121.
[0050] like Figures 5 to 7 As shown, in one embodiment, the partition 125 is arranged horizontally, and the second cavity 1253 is located above the first cavity 1252, and the second air outlet 1251 is arranged one-to-one with the first air outlet 1223, so that the airflow in the second cavity 1253 is ejected downward through the second air outlet 1251 and then enters the cooking cavity 111 through the first air outlet 1223, and the aperture of the second air outlet 1251 is smaller than the aperture of the first air outlet 1223, so as to avoid the first air outlet 1223 interfering with the flow of the airflow ejected from the second air outlet 1251. Due to the different apertures of the second air outlet 1251 and the first air outlet 1223, the ejection amount and ejection intensity of the ejected airflow passing through the second cavity 1253 and the second air outlet 1251 are different from those of the airflow ejected directly from the first cavity 1252 and the first air outlet 1223.
[0051] like Figure 6 and Fig.10As shown, in one embodiment, the first baffle 123 is located in the first cavity 1252, and the air intake assembly 120 further includes a second baffle 126 rotatably connected to the injection box 122 and located in the second cavity 1253. Fig. 9 As shown, the second baffle 126 is provided with a second avoidance opening 1261 arranged opposite to the first avoidance opening 1231. Figure 7 and Figure 8 As shown, when the second baffle 126 is attached to the partition 125, the second air outlet 1251 located opposite to the second avoidance opening 1261 is connected to the first cavity 1252 and the second cavity 1253, so that the airflow into the second cavity 1253 can only enter the cooking cavity 111 through the second air outlet 1251 located opposite to the second avoidance opening 1261, so that the second cavity 1253 is connected to the first cavity 1252 through the specific second air outlet 1251 (i.e., located opposite to the second avoidance opening 1261) by rotating the second baffle 126. and the cooking cavity 111, thereby realizing that the jet component 121 is connected to the first cavity 1252 and the cooking cavity 111 through the specific second air outlet 1251, and realizing that the airflow ejected by the jet component 121 is only sprayed into the cooking cavity 111 at the specific air outlet, so that the cold airflow or the hot airflow is introduced into the air inlet 1121 at the specific position of the cooking cavity 111 (that is, the second avoidance port 1261), thereby breaking the original airflow stratification phenomenon at the specific position, enhancing the mixing and diffusion of the air, and achieving the uniform heating effect on the specific position of the cooking cavity 111.
[0052] like Fig. 9 As shown, in one embodiment, the second avoidance opening 1261 has the same structure as the first avoidance opening 1231, and the first baffle 123 and the second baffle 126 are connected to rotate synchronously, and the distance between the first baffle 123 and the second baffle 126 in the height direction is consistent with the height of the first cavity 1252, so that when the first baffle 123 is attached to the bottom plate 1222, the second baffle 126 is attached to the partition 125, so that the effect of jetting to a specific air outlet is achieved by rotating the first baffle 123 and the second baffle 126. In other embodiments, the structures of the second avoidance opening 1261 and the first avoidance opening 1231 may also be different, and the first baffle 123 and the second baffle 126 may also rotate separately. At this time, although the control method for limiting the jetting of a specific air outlet is more complicated, it can be achieved and will not be described in detail here.
[0053] like Figures 5 to 9 As shown, in one embodiment, the first avoidance opening 1231 is a fan-shaped structure, such as Figure 8As shown, for the sake of convenience, the second avoidance opening 1261 having the same structure as the first avoidance opening 1231 is compared with the second outlet opening 1251 having the same distribution as the first outlet opening 1223. The circle corresponding to the first avoidance opening 1231 and the circle corresponding to the first outlet opening 1223 adjacent to the first outlet opening 1223 in the same circumferential direction are concentric circles, and the center angle of the first avoidance opening 1231 is α, and the center angle of the first outlet opening 1223 adjacent to the first outlet opening 1223 in the same circumferential direction is β, and β≤α≤2β.
[0054] It is understandable that the distance that the driving member 1241 and the driving shaft drive the first baffle 123 and the second baffle 126 to move in the axial direction of the transmission shaft 1242 is limited by the height of the first cavity 1252 and the second cavity 1253, and the movable distance should not be greater than the minimum height between the first cavity 1252 and the second cavity 1253. Since the aperture of the first gas outlet 1223 corresponding to the first cavity 1252 is larger, the gas flow rate ejected from the first cavity 1252 is larger. In one embodiment, the height of the first cavity 1252 is greater than that of the second cavity 1253 to adapt to the first cavity 1252 with a larger flow rate.
[0055] like Figure 3 and Figure 4 As shown, in one embodiment, the jet component 121 can also be selectively connected to the first cavity 1252, and the jet component 121 is connected to the first cavity 1252 through the connecting pipe 129. Optionally, the connecting pipe 129 can be set to be on and off, for example, a valve body for controlling the on and off of the connecting channel is set in the connecting pipe 129, so that the jet component 121 can be selectively connected to the first cavity 1252. The connecting pipe 129 connected to the first cavity 1252 and the connecting pipe 129 and the connecting pipe 129 connected to the second cavity 1253 are independently set and independently controlled, so that the jet component 121 can be selectively connected to the first cavity 1252 and the second cavity 1253 or the jet component 121 is connected to the first cavity 1252 and the second cavity 1253 at the same time, thereby adapting to different requirements for ejecting gas. Preferably, the diameter of the connecting pipe 129 connected to the first cavity 1252 and the connecting pipe 129 is larger than that of the connecting pipe 129 connected to the second cavity 1253, so that the flow rate entering the first cavity 1252 is larger.
[0056] like Figure 2 and Figure 4As shown, in one embodiment, the cooking device 100 further includes a cold air flow source 127, which is used to store cold air. The jet element 121 is connected to the cold air flow source 127 to drive the cold air to be sprayed into the cooking cavity 111, so as to cool down the temperature in the cooking cavity 111. The cold air flow source 127 is generated by a refrigeration device or by introducing external cold air, and can reduce the temperature of the sprayed air flow to adjust the local air flow temperature to be too high, so as to avoid drying or charring of the food surface caused by overheating. It can be understood that the cold air in the cold air flow source 127 refers to an air flow with a temperature lower than the hot air in the hot air flow source 128. Preferably, the temperature of the cold air in the cold air flow source 127 is lower than the cooking temperature in the cooking cavity 111, so as to cool down the temperature in the cooking cavity 111. However, in other embodiments, the cold air in the cold air flow source 127 may be no lower than the cooking temperature in the cooking cavity 111. In this case, the cold air sprayed into the cooking cavity 111 is used to maintain a stable balance or slightly increase the temperature in the cooking cavity 111, and the hot air in the hot air flow source 128 is sprayed into the cooking cavity 111 to significantly increase the temperature in the cooking cavity 111.
[0057] like Figure 2 and Figure 4 As shown, in one embodiment, the cooking device 100 further includes a hot air flow source 128, which is used to store hot air. The jet element 121 is connected to the hot air flow source 128 to drive the hot air to be sprayed into the cooking cavity 111, so as to increase the temperature in the cooking cavity 111. The hot air flow source 128 is generated by heating the air with a heating element, and the temperature of the sprayed air flow is increased to adjust the low temperature of the local air flow, so as to ensure that the hot air maintains an appropriate temperature when sprayed onto the surface of the food, which is conducive to uniform coloring. It can be understood that the hot air in the hot air flow source 128 refers to an air flow with a temperature higher than that of the cold air in the cold air flow source 127. Preferably, the temperature of the hot air in the hot air flow source 128 is not lower than the cooking temperature in the cooking cavity 111, so as to increase the temperature in the cooking cavity. However, in other embodiments, the temperature in the hot air flow source 128 may be no higher than the cooking temperature in the cooking cavity 111. In this case, the hot air spraying cooking cavity 111 is used to maintain a stable balance or slightly reduce the temperature in the cooking area, and the cold air in the cold air flow source 127 is sprayed into the cooking cavity 111 to significantly reduce the temperature in the cooking cavity 111.
[0058] like Figure 1 and Figure 3As shown, in one embodiment, the cooking device 100 further includes a detection member 130, which is disposed toward the cooking cavity 111 and is used to photograph and analyze cooking information of the food in the cooking cavity 111. The air intake component 120 is controlled by the detection member 130 and adjusts the airflow ejected toward the cooking cavity 111 according to the cooking information. Exemplarily, the detection member 130 may be a photographing member with a photographing function and an analyzing member with an image processing function, so as to monitor the cooking food inside the cooking cavity 111 in real time, and control the air intake component 120 to eject airflow at a specific position according to whether the cooking food needs to be heated or cooled, or control the airflow ejected by the air intake component 120 to eject airflow with a stronger or weaker airflow intensity.
[0059] In one embodiment, the air intake assembly 120 further includes an airflow regulating member 150 connected between the jet element 121 and the hot airflow source 128 or between the jet element 121 and the cold airflow source 127 to regulate the flow rate and pressure of the airflow entering the jet element 121. In this embodiment, the airflow regulating member 150 is a pressure sensor and a flow meter.
[0060] When the cooking device 100 provided by the above solution is used, the detection component 130 confirms the cooking information of the food in the cooking cavity 111 and analyzes the next cooking requirements, and the air intake component 120 adjusts the working mode according to the cooking requirements. The working modes of the air intake component 120 are: 1. A large flow injection mode, which is suitable for the preheating stage of food cooking. The jet component 121 is connected to the first cavity 1252. After the airflow enters the first cavity 1252, it enters the cooking cavity 111 through the first air outlet 1223 and the air inlet 1121, so that the original airflow stratification phenomenon is broken by the large-flow jet airflow, the mixing and diffusion of the air is enhanced, and the uniformity of different layers of the cavity is improved; 2. A small flow injection mode, which is suitable for the situation where the food is partially lightly colored. The jet component 121 is connected to the second cavity 1253. After the airflow enters the second cavity 1253, it enters the cooking cavity 111 through the second air outlet 1251, the first air outlet 1223 and the air inlet 1121. Since the aperture of the second air outlet 1251 is smaller, the injection area of the airflow is smaller, so that the airflow is concentrated on the surface of the food, and the color of the food surface is adjusted; or it is suitable for the area where the food is locally darkly colored, and the cold airflow is sprayed to cool down and avoid the carbonization of the food surface.
[0061] The cooking device 100 provided in the above scheme, by arranging a plurality of air inlet holes 1121 distributed in an array on the top of the cooking cavity 111, and arranging an injection member 121 that can be selectively connected to each air inlet hole 1121, so that the airflow injected into the cooking cavity 111 can select the air inlet holes 1121 at different positions to enter the cooking cavity 111, and the airflow is only injected into the cooking cavity 111 at the selected specific air outlet holes, so that cold airflow or hot airflow is introduced into the air inlet holes 1121 at specific positions of the cooking cavity 111, thereby breaking the original airflow stratification phenomenon at specific positions inside the cooking cavity 111, enhancing the mixing and diffusion of air, and thereby achieving a uniform heating effect on specific positions of the cooking cavity 111. It is suitable for the case where the heating degree needs to be increased or decreased at specific positions of the food during the cooking process.
