DETAILED DESCRIPTION

[0021] The specific embodiments of the present application are described below with reference to the accompanying drawings. In order to fully understand the present application, many details are described below, but the present application can be implemented without these details for those skilled in the art.

[0022] Referring to FIGS. 1-4, an air fryer with heat preservation function includes a machine body 100 and a heat preservation disc 500. The machine body 100 is provided with a cooking cavity 200, a hot air channel 300 and a heat preservation cavity 400 which are in communication with each other. The heat preservation disc 500 is arranged outside the heat preservation cavity 400. The heat preservation cavity 400 is provided with a heat supply part and a hot gas outlet part. The heat supply part is used to supply heat to the heat preservation disc 500. The hot gas outlet part is used to discharge hot gas in the heat preservation cavity 400. The present application is provided with the heat supply part and the hot gas outlet part which are independent of each other on the heat preservation cavity 400. Thus, the heat in the hot air in the cooking cavity 200 is fully utilized to realize heat transfer, so as to heat and preserve the heat preservation disc 500. The hot gas and moisture in the hot air which contain food to be cooked are discharged from the hot gas outlet part and do not enter the heat preservation disc 500, so as not to affect the taste and mouthfeel of the food to be preserved. The problems existing in the prior art are effectively solved.

[0023] Referring to FIGS. 2 and 3, in the present embodiment, the heat preservation cavity 400 is arranged on the top of the cooking cavity 200, and the hot air channel 300 is arranged on the side of the cooking cavity 200. Specifically, the cooking cavity 200 is provided with an air fryer group 210. The top of the cooking cavity 200 is provided with a fixing cover 220 for fixing a heating assembly. The side wall of the fixing cover 220 is provided with a ventilation port 221 which is in communication with the hot air channel 300. The heating assembly includes a heating pipe 230, a uniform heating fan 240, a heat dissipation fan 250 and a motor 260. The heating pipe 230 is used to heat the cooking cavity 200. The uniform heating fan 240 can improve the heat transfer efficiency and uniformly transfer the heat of the heating pipe 230 to each corner of the cooking cavity 200. The heat dissipation fan 250 can dissipate heat for the motor 260, thereby prolonging the service life of the motor 260. When the heating assembly works, part of the hot air is transferred to the air fryer group 210 to heat the food to be cooked. Another part of the heat directly enters the hot air channel 300 from the ventilation port 221 of the fixing cover 220 and is then transferred to the heat preservation cavity 400. Thus, the risk of flavoring can be reduced as much as possible from the source, and the hot gas and moisture containing the food to be cooked in the air fryer group 210 can be prevented from entering the heat preservation cavity 400.

[0024] Referring to FIGS. 1-3, in the present embodiment, the heat supply part is arranged on the top of the heat preservation cavity 400, and the hot gas outlet is arranged on the side wall of the heat preservation cavity 400. In operation, the heat preservation plate 500 is arranged above the heat supply part, and the hot air in the heat preservation cavity 400 transmits heat to the bottom of the heat preservation plate 500 through the heat supply part, thereby achieving the effect of heating and preserving the food to be preserved, and the hot gas in the hot air is discharged from the hot gas outlet on the side wall of the heat preservation cavity 400, thereby being isolated from the food to be preserved and avoiding the risk of flavoring.

[0025] Referring to FIGS. 2-4, the heat preservation cavity 400 is provided with a hot air inlet 410 and a hot air outlet 420 for the hot air channel 300 and the hot gas outlet, respectively, and a hot gas flow channel 430 arranged in a meandering manner is arranged between the hot air inlet 410 and the hot air outlet 420; the heat supply part is arranged above the hot gas flow channel 430. By arranging the hot gas flow channel 430 in a meandering manner between the hot air inlet 410 and the hot air outlet 420, the hot air flow rate can be reduced, the heat transfer effect can be improved, and it can be ensured that the heat in the hot air is fully transmitted to the heat preservation plate 500, thereby improving the heat preservation effect.

[0026] Referring to FIGS. 2-4, in order to further optimize the structure of the hot gas flow channel 430, the hot air inlet 410 and the hot air outlet 420 are arranged on the same side of the heat preservation cavity 400, and the hot air flow channel is designed as a U-shaped flow channel communicated between the hot air inlet 410 and the hot air outlet 420. Specifically, a plurality of hot air outlets 420 are arranged on both sides of the hot air inlet 410, and two baffles 431 are arranged at the bottom of the heat preservation cavity 400 to isolate the hot air inlet 410 and the hot air outlet 420 from each other, thereby forming two U-shaped flow channels in the heat preservation cavity 400. The hot air from the cooking cavity 200 enters the heat preservation cavity 400 through the hot air channel 300 and is divided into two paths by the baffles 431 and is uniformly discharged from the hot air outlets 420, thereby ensuring that the heat in the hot air is uniformly transmitted to the heat supply part, and the heat preservation plate 500 is uniformly heated.

[0027] Referring to FIGS. 2-4, specifically, the heat supply part is a hollow part 440 arranged on the top of the heat preservation cavity 400, and the heat preservation plate 500 is placed in the hollow part 440. This design can ensure that the hot air and the food to be preserved are isolated from each other, and the bottom of the heat preservation plate 500 is in direct contact with the hot air, thereby improving the heat conduction effect and reducing unnecessary heat loss.

[0028] Referring to FIGS. 1-3, in actual application, a heat preservation cover (not shown in the figure) can be designed to cover the outside of the heat preservation plate 500 if necessary, thereby further improving the heat preservation effect. The structure of the heat preservation cover can be designed according to actual needs, which is not limited herein.

[0029] The above merely is the specific implementation manner of the present application, but the design concept of the present application is not limited to this, and any non-essential change of the present application by using the concept should belong to the act of infringing the protection scope of the present application.
