[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0036] like Figure 1-6 A cooking device with a heat preservation function is shown, comprising a shell 1, a fan assembly, a heating assembly and a control assembly, wherein a heating chamber 11 for cooking food and a mounting groove 112 located at the top of the heating chamber 11 and connected to the heating chamber 11 are provided inside the shell 1; the fan assembly at least comprises a first fan blade 21 arranged in the mounting groove 112; the heating assembly comprises a first heating element and a second heating element arranged in the heating chamber 11 and below the first fan blade 21; under the action of the first fan blade 21, air heated by the first heating element and the second heating element can be directed to food to heat it; the control assembly comprises a first control component 14 and a second control component 15, wherein the first control component 14 is used to control the heating of the first heating element, and the second control component 15 is used to control the heating of the second heating element; wherein, when the food placed in the heating chamber 11 needs to be kept warm, the first heating element can be controlled to be turned off by the first control component 14, and the second heating element can be controlled to be started by the second control component 15 to achieve heat preservation.

[0037] On the basis of the above structure, when using the cooking device with heat preservation function of the utility model, the user can select the heating method according to the volume of the food placed in the heating cavity 11. For example, when the volume of the food placed in the heating cavity 11 by the user is large, the user can control the first heating element and the second heating element to heat and cook the food through the first control member 14 and the second control member 15 at the same time to improve the cooking efficiency of the food. Of course, the user can also only control the first control member 14 to heat the first heating element to cook the food. After the food is cooked, the user can control the first heating element to turn off through the first control member 14, and control the second heating element to start heating through the second control member 15 to achieve heat preservation of the food. It should be noted that, in the present embodiment, the heating power of the first heating element is much greater than the heating power of the second heating element. Secondly, in other cases, the first control member 14 and the second control member 15 can be control knobs, or the first heating element and the second heating element are controlled by a control screen, and no specific limitation is made here.

[0038] See also Figure 2-6 , the first heating element is arranged directly below the first fan blade 21, and the second heating element is arranged on both sides of the first heating element. The first heating element is a spiral heating tube 111, and the second heating element is two first linear heating tubes 113, and the two first linear heating tubes are respectively arranged on both sides of the spiral heating tube 111. Specifically, the cooking device with heat preservation function of the utility model also includes a pressing sheet 115, the spiral heating tube 111 includes a first heating body 1111 and a first support 1112 located on one side of the first heating body 1111, and the first heating body 1111 also has a first conductive end 1113 for power supply. When installing, the first heating body 1111 is placed in the installation groove 112 of the heating cavity 11, and the first support 1112 on one side is fixed to the inner wall of the heating cavity 11 by fasteners, and then the other side of the first heating body 1111 is fixed to the inner wall of the heating cavity 11 by the pressing sheet 115, and at the same time, the first conductive end extends out of the heating cavity 11 for conduction. Among them, the first linear heating tube 113 includes a second heating body 1131 and a second support 1132 located at one end of the second heating body 1131, and both ends of the second heating body 1131 are provided with second conductive ends 1133 for conduction. The two first linear heating tubes 113 are passed through the heating chamber 11 and are respectively located on both sides of the spiral heating tube 111, and the second heating body 1131 is placed in the heating chamber 11, the second conductive end 1133 and the second support 1132 are located outside the heating chamber 11, and the second support 1132 is fixed to the outer wall of the heating chamber 11 by fasteners.

[0039] Furthermore, the cooking device with heat preservation function of the utility model further includes a third heating element arranged at the bottom of the heating cavity 11, and the third heating element is controlled by the second control component 15. The third heating element is two second linear heating tubes 114, and the two second linear heating tubes 114 are arranged correspondingly to the two first linear heating tubes 113. In this embodiment, the second linear heating tubes 114 have the same structure as the above-mentioned first linear heating tubes 113.

[0040] Thus, when the user controls the second heating element to heat and the third heating element to keep warm through the second control unit 15, the two first linear heating tubes 113 heat and heat the upper surface of the food, and the two second linear heating tubes 114 heat and heat the lower surface of the food, so as to achieve efficient heating and heat preservation of the food. It should be noted that the heating power of the first linear heating tube and the second linear heating tube is relatively low, and the heating power can be controlled by the second control unit 15 to achieve heating and heat preservation of the corresponding volume of food, and the food will not be overheated, thereby burning the food.

[0041] Specifically, the inner wall of the installation groove 112 is formed with a guide slope 1121 , and the two first linear heating tubes 113 are both located below the guide slope 1121 . The guide slope 1121 is used to guide air to the first linear heating tubes 113 for heating.

[0042] Furthermore, the fan assembly also includes a drive motor 2 arranged inside the shell 1 and outside the heating chamber 11 , and the output shaft of the drive motor 2 extends into the heating chamber 11 and is drivingly connected to the first fan blade 21 .

[0043] Specifically, when the driving motor 2 drives the first fan blade 21 located in the heating chamber 11 to rotate, the first fan blade 21 drives the air in the heating chamber 11 to flow, and at the same time, under the action of the guide slope 1121, the air is guided to the first linear heating tube 113 for heating, so that the hot flow air heats and cooks the food in the heating chamber 11.

[0044] Furthermore, the fan assembly also includes a second fan blade 22 which is also sleeved on the output shaft of the driving motor 2 and located outside the heating chamber 11 , and the second fan blade 22 is used for exhausting air and dissipating heat.

[0045] See also Figure 2 , Figure 7 The housing 1 is provided with a heat dissipation net 13, and a heat dissipation port 1122 connected to the heat dissipation net 13 is opened in the mounting groove 112. When the driving motor 2 drives the second fan blade 22, the airflow blown by the second fan blade 22 can dissipate the heat in the heating chamber 11 to the outside (such as Figure 2 as indicated by the arrow).

[0046] See also Figure 3The cooking device with heat preservation function of the present invention further includes a temperature sensor 116, which is arranged in the heating cavity 11 and is used to monitor the internal temperature thereof.

[0047] Specifically, the cooking device with heat preservation function of the present invention further comprises a door body 12, which is used to seal the heating cavity 11, so as to place food into the heating cavity 11 and seal the heating cavity 11 for heating and heat preservation.

[0048] In summary, the cooking device with heat preservation function of the utility model is provided with a spiral heating tube 111, a first linear heating tube 113 and a second linear heating tube 114. After the food is heated, the first control component 14 controls the spiral heating tube 111 to turn off the heating, and the second control component 15 controls the first linear heating tube 113 and the second linear heating tube 114 to turn on the heating and heat preservation, thereby avoiding the high-temperature air in the heating chamber 11 from forming water vapor and ensuring the taste of the cooked food. At the same time, the user can choose to control the heating of the spiral heating tube 111 according to the amount of food, or control the spiral heating tube 111, the first linear heating tube 113 and the second linear heating tube 114 at the same time, which can enrich the heating methods and enhance the user experience.

[0049] Furthermore, by setting a guide slope 1121 in the installation groove 112, when heating food, the driving motor 2 drives the first fan blade 21 to rotate, and the airflow blown out by the first fan blade 21 is diffused by the guide slope 1121, and the high-temperature air around the spiral heating tube 111 is blown onto the food in the heating cavity 11. At the same time, the first linear heating tube 113 and the second linear heating tube 114 provide auxiliary heating, thereby improving the heating efficiency of the food in the heating cavity 11 and ensuring the taste of the cooked food.
