Description

Technical Field

[0001] The utility model relates to the technical field of cooking utensils, in particular to a core component with a cooling air duct and a cooking device. Background Art

[0002] The air fryer mainly uses air to replace the hot oil in the frying pan, so that the food to be cooked gradually becomes cooked; at the same time, the hot air blows away the moisture on the surface of the food, making the ingredients achieve an effect similar to frying. The basic working principle of the air fryer is "high-speed air circulation technology". It generates hot air by heating the heat pipe inside the machine at high temperature, and then uses a fan to blow the high-temperature air into the pot to heat the food, so that the hot air circulates in a closed space, and uses the fat of the food itself to fry the food, thereby dehydrating the food and making the surface golden and crispy, achieving the effect of frying.

[0003] In actual use environments, especially double-pot air fryers, they can cook multiple different types of food at the same time, which not only has a wider range of applications but also improves cooking efficiency. However, existing double-pot air fryers usually extend a partition on the lower movement to form a double cavity. However, in the actual operation scenarios of some air fryers, the partition is prone to become a high-temperature dead corner. After the air fryer is used for a long time, this part is prone to certain abnormal conditions such as thermal deformation or sol. Utility Model Content

[0004] The utility model provides a core component with a cooling air duct which can isolate the air duct and guide the fluid, especially can dynamically cool down the high-temperature dead corner.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A core assembly with a cooling air duct comprises a lower core, wherein the lower core has at least two cooking cavities, and an isolation air duct is provided between two adjacent cooking cavities; a cold air outlet is provided between the two adjacent cooking cavities, and a fluid flows into the isolation air duct through the cold air outlet to form an air duct cooling path; a mixing air port is provided between the two adjacent cooking cavities, and part of the fluid in the isolation air duct flows through the mixing air port, or part of the fluid in the isolation air duct and part of the fluid around the lower core are mixed and then flow through the mixing air port.

[0007] The principles and advantages of this solution are as follows: by arranging at least two cooking cavities, a variety of different or same types of ingredients can be cooked at the same time, with a wide range of applications, while also improving cooking efficiency; by arranging an isolation duct between the two cooking cavities, not only can the main structures of the two adjacent cooking cavities be disconnected, so that the isolation duct can cool down the two adjacent cooking cavities simultaneously, but also the flow path of the airflow can be guided, so that the high-temperature airflow is not easy to be retained, especially between the two cooking cavities, to avoid the gas there from constantly absorbing heat and generating a local high temperature, thereby improving the cooling effect; by arranging a mixing air outlet, it is convenient to mix part of the heated gas in the isolation air duct with part of the low-temperature gas around the lower core, so as to appropriately cool the entirety, and then discharge it through the mixing air outlet, which helps to reduce the temperature around the usage scene.

[0008] Preferably, as an improvement, a connecting portion is provided between the side walls of two adjacent cooking cavities, the cold air outlet and the mixing air outlet are both provided on the connecting portion, and the side walls of the two adjacent cooking cavities and the connecting portion together enclose an isolation air duct.

[0009] Beneficial effect: The above technical solution is adopted to facilitate the formation of an isolation air duct through the side wall and the connecting part of the cooking cavity; it is also convenient for the arrangement of the cold air outlet and the mixing air outlet. Since the cold air outlet and the mixing air outlet are both located on the connecting part, the circulation speed of the airflow in the isolation air duct can be relatively increased, so that the airflow can take away more heat relatively quickly, further improving the cooling effect under working conditions and further avoiding high-temperature dead corners.

[0010] Preferably, as an improvement, an upper movement is mounted on the lower movement, and the upper movement has at least two cover parts, and the cover parts are used to install a cooling fan assembly; the cover parts have an air inlet, and the cover parts have a main air outlet.

[0011] Beneficial effect: The adoption of the above technical solution not only facilitates the installation of the cooling fan assembly, but also, under the action of the cooling fan assembly, introduces the airflow from the air inlet into the cover portion, and makes most of the airflow be sent out from the main air outlet, thereby further enhancing the cooling effect at the upper movement.

[0012] Preferably, as an improvement, an air guide port is provided on the cover shell portion, and an air guide channel is connected between the air guide port and the isolation air duct; the cooling fan assembly draws gas from the air inlet and guides part of the gas into the air guide channel.

[0013] Beneficial effect: The above scheme is advantageous in that, during actual use, part of the gas in the cover shell part flows in sequence along the path of the air guide port, the air guide channel, the cold air outlet, and the isolation air duct through the cold fan assembly, so that the gas in the isolation air duct flows, thereby reducing the cooling dead corner between the two cooking cavities.

[0014] Preferably, as an improvement, the upper movement is provided with a lateral mixing air outlet, and the lateral mixing air outlet is connected to the mixing air outlet.

[0015] Beneficial effect: By adopting the above technical solution and arranging the mixing air outlet, it is convenient for some of the heated gas in the isolation air duct to mix with some of the low-temperature gas around the lower movement, and then the overall temperature is moderately cooled, and then discharged through the mixing air outlet, which helps to reduce the temperature around the use scene; at the same time, it also forms a multi-path gas circulation in the isolation air duct, further improving the overall cooling effect.

[0016] Preferably, as an improvement, an air guide is installed on the upper core, and a structural hole matching the cold air outlet and the mixing air outlet is opened on the air guide.

[0017] Beneficial effect: The above scheme is conducive to improving the sealing effect of the air guide channel, the cold air outlet and the mixing air outlet, reducing the possibility of cold air flow loss at their connections, thereby ensuring a relatively constant delivery flow and speed of the cold air flow.

[0018] Preferably, as an improvement, an air guide groove is provided on the upper movement, and the air guide channel is connected to the isolation air duct through the air guide groove.

[0019] Preferably, as an improvement, a partition is provided in the air guide groove to separate the fluids of two adjacent air guide channels at the air guide groove.

[0020] Beneficial effect: It is convenient to avoid the fluid connection between two adjacent air guide channels at the air guide groove, thereby avoiding air flow offset, and allowing the air flow to enter the isolation air duct from relatively different cold air outlets, which is convenient to increase the circulation speed of the air flow in the isolation air duct, so that the air flow can take away more heat relatively quickly, further improving the cooling effect.

[0021] The present application also provides a cooking device, comprising a cooking device body and a core assembly with a cooling air duct, wherein the core assembly with the cooling air duct is installed on the cooking device body.

[0022] Preferably, as an improvement, the cooking device body comprises an outer shell, the lower core and the upper core constitute an inner shell, a cold air channel is formed between the inner shell and the outer shell, and the cold air channel is communicated with the isolation air duct.

[0023] Beneficial effect: By adopting the above technical solution, part of the airflow in the isolation air duct continues to move downward, and after touching the bottom of the outer shell and based on the guidance and restriction of the side walls and bottom walls of the two cooking cavities, part of the airflow disperses to both sides, flowing through the outer surface of the lower core and the upper core along the cold air channels on both sides, thereby forming a relative internal circulation, reducing the temperature inside the entire device and extending the service life of the device.

[0038] Embodiment 1

[0039] This embodiment is basically as shown in the attached Figure 1 -Attached Figure 7 As shown:

[0040] A core assembly with a cooling air duct comprises a lower core 100. The lower core 100 is provided with at least two cooking cavities 101, and an isolation air duct 102 is provided between two adjacent cooking cavities 101.

[0041] In this embodiment, the number of cooking cavities 101 is preferably two.

[0042] Based on the design of the isolation air duct 102, the main structures of the two cooking chambers 101 are not connected. Figure 1 And attached Figure 4 As shown, the main structure sides of the side walls A and B of the left and right cooking cavities 101 are not connected, so that the isolation duct 102 can cool down the two adjacent cooking cavities 101 simultaneously, and can also limit and guide the flow path of the airflow, so that the high-temperature airflow is not easy to be retained, especially between the two cooking cavities 101, to avoid the gas there from constantly absorbing heat and generating a locally high temperature, thereby improving the cooling effect.

[0043] Specifically, as attached Figure 1 And attached Figure 4 As shown, the cooking cavity 101 on the left is larger than the cooking cavity 101 on the right, and the cooking pot group 300 adapted in the cooking cavity 101 on the left is synchronously larger than the cooking pot group 300 adapted in the cooking cavity 101 on the right.

[0044] In the above scheme, a cold air outlet 103 is opened between two adjacent cooking cavities 101, and the fluid flows into the isolation air duct 102 through the cold air outlet 103 to form an air duct cooling path; a mixing air outlet 104 is opened between two adjacent cooking cavities 101, and part of the fluid in the isolation air duct 102 flows through the mixing air outlet 104, or part of the fluid in the isolation air duct 102 and part of the fluid around the lower core 100 are mixed and then flow through the mixing air outlet 104.

[0045] Specifically, the number of the cold air outlets 103 is two, and the number of the mixing air outlet 104 is one. Preferably, the two cold air outlets 103 are adjacent to each other.

[0046] To facilitate the arrangement of the cold air outlet 103 and the mixing air outlet 104, in the present embodiment, a connecting portion 110 is provided between the side walls of two adjacent cooking cavities 101, that is, the upper ends of the two cooking cavities 101 are laterally connected by the connecting portion 110, the cold air outlet 103 and the mixing air outlet 104 are both provided on the connecting portion 110, and the side walls of the two adjacent cooking cavities 101 and the connecting portion 110 together enclose an isolation air duct 102.

[0047] The upper movement 200 is mounted on the lower movement 100, and the upper movement 200 has at least two housing parts 210, and the housing parts 210 are used to install a cooling fan assembly (not marked in the figure); the housing parts 210 have an air inlet 211, and the housing parts 210 have a main air outlet 212. During assembly, the upper movement 200 and the lower movement 100 are assembled and connected using matching screws or screws.

[0048] Preferably, the upper movement 200 has two cover parts 210, which protrude relatively outward from the upper movement 200. In actual use, the cooling fan assembly needs to be adapted and installed inside the cover part 210, and the air intake path of the air inlet 211 is roughly perpendicular to the air outlet path of the main air outlet 212.

[0049] An air guide port 213 is provided on the inner edge of the cover shell portion 210, and an air guide channel 201 is connected between the air guide port 213 and the isolation air duct 102, that is, two air guide channels 201 are provided on the upper movement 200, and the air guide channels 201 protrude relatively outward from the upper movement 200, and there is a gap between the two air guide channels 201; the cold fan assembly draws gas from the air inlet 211 and guides part of the gas into the air guide channel 201.

[0050] In order to further improve the cooling effect, in the above technical solution, the upper movement 200 is provided with a lateral mixing air outlet 202, and the lateral mixing air outlet 202 is connected with the mixing air outlet 104, that is, the airflow flowing out of the mixing air outlet 104 flows out from the lateral mixing air outlet 202, so that a multi-path gas flow circulation is formed in the overall structure, thereby further improving the overall cooling effect.

[0051] Furthermore, an air guide 220 is installed on the upper core 200, and a structural hole 221 is provided on the air guide 220 to match the cold air outlet 103 and the mixing air outlet 104. This helps to improve the sealing effect of the air guide channel 201, the cold air outlet 103 and the mixing air outlet 104, and reduces the possibility of cold air flow loss at the connection point, thereby ensuring a relatively constant delivery flow and speed of the cold air flow.

[0052] Specifically, the upper movement 200 is provided with an air guide groove 203, and the air guide member 220 is installed on the air guide groove 203. The air guide member 220 has two ear plates 222. When installing, the air guide member is installed on the upper movement 200 using matching screws or screws. The air guide channel 201 communicates with the isolation air duct 102 through the air guide groove 203.

[0053] Furthermore, a partition 204 is provided in the air guide groove 203. Specifically, there are two partitions 204, so that the fluid of two adjacent air guide channels 201 is separated at the air guide groove 203. It is convenient to avoid the fluid connection of the two adjacent air guide channels 201 at the air guide groove 203, thereby avoiding the airflow from counteracting each other, and allowing the airflow to enter the isolation air duct 102 from relatively different cold air outlets 103, so as to improve the circulation speed of the airflow in the isolation air duct 102, so that the airflow can take away more heat relatively quickly, and further improve the cooling effect; when the cooking cavity 101 is operated in one of the selected working states, that is, the cold fan assembly on the left or right side is operated alone, it can be correspondingly avoided that part of the cold air on the working side enters the other side in the non-working state along the air guide groove 203, which helps to reduce the cold air loss and improve the stability of the cold air moving path, so that the cooling is more stable.

[0054] Embodiment 2

[0055] This embodiment is basically as shown in the attached Figure 8 -Attached Fig.11 As shown:

[0056] A cooking device, namely, an air fryer, comprises a cooking device body and a core component with a cooling air duct, wherein the core component with the cooling air duct is installed on the cooking device body.

[0057] Specifically, the cooking device body includes an outer shell 10, and a lower core 100 and an upper core 200 constitute an inner shell. The lower core 100 and the upper core 200 are placed inside the outer shell 10, and a cold air channel 11 is formed between the inner shell and the outer shell 10, and the cold air channel 11 is connected to the isolation air duct 102.

[0058] An air inlet 12 is provided on the outer shell 10. Specifically, the air inlet 12 is divided into at least two parts, one of which is opened at the bottom of the outer shell 10 and is evenly arranged with a plurality of air inlets, and the other part is opened at the top of the outer shell 10 in the shape of a rectangular ring connected end to end; the air inlet 12 at the bottom of the outer shell 10 is communicated with the cold air channel 11.

[0059] When used specifically, Figure 1 -Attached Fig.11As shown, the cold fan assembly drives the air above the upper movement 200 and the cold air sucked in from the top air inlet 12 to mix and enter the corresponding cover shell part 210 together. Under the action of the cold fan assembly, part of the air is sent out along the main air outlet 212. The main air outlet 212 is located on the back side of the outer shell 10, thereby preventing the outflowing air flow from causing burns to the user; another part of the air flows along the air guide port 213, the air guide channel 201, the air guide groove 203, and the cold air outlet 103 in sequence to the isolation air duct 102, so that the air in the isolation air duct 102 is cooled and cooled, that is, the side wall structure of the cooking cavity 101 on both sides is cooled and cooled.

[0060] Due to the structure of the two cooking cavities 101, the cold air outlet 103, the mixing air outlet 104 and the cold air channel 11, part of the air flow here will be divided into multiple parts. A part of the flowing air flow continues to move downward, and after touching the bottom of the outer shell 10, it disperses and flows to both sides, and flows through the entire lower movement 100 and the outer surface of the upper movement 200 along the cold air channels 11 on both sides. When the air flow flows through the bottom of the lower movement 100, it mixes with the cold air sucked in by the air inlet 12 located at the bottom of the outer shell 10, and then flows to the top of the upper movement 200 together, and is again guided by the cold fan assembly for a new circulation, thereby forming a relative internal circulation to reduce the temperature inside the entire device.

[0061] There is also a part of the flowing airflow that mixes with the cold air sucked in from the air inlet 12 at the bottom of the outer shell 10, and flows to the top of the upper movement 200 through the mixing air port 104, the air guide groove 203, and the lateral mixing air outlet 202 in sequence, thereby forming a cold air flow cycle. The cooling work is completed by multiple internal loops, and the multiple internal loops all pass through the isolation air duct 102, which can achieve a better cooling effect on the cooling dead corner of the isolation air duct 102.

[0062] It should be noted that in the solution of this embodiment, other internal structures of the cooking device and its corresponding control structure are existing technologies, and the detailed structure and principle will not be explained here.

[0063] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
