When the air fryer burner works, hot air blows into the cooking cavity, and the excess hot air needs to be discharged out of the machine. In addition, the heat that needs to be dissipated by some electronic components in the machine is usually also discharged out of the machine in the form of wind. When this heat is discharged out of the machine, the temperature is usually relatively high, and the air outlet of the machine is usually set at the rear side of the machine. The hot air blows directly to the wall at the rear side of the machine, which easily causes the wall temperature to rise too quickly, which does not meet the requirements. Summary of the invention

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the present invention.

[0049] like Figures 1 to 6 As shown, this embodiment provides an air-frying cooking device equipped with a steam generating system, comprising:

[0050] A machine body 1, wherein a cooking cavity and an air frying burner for heating the cooking cavity are provided in the machine body 1, and an exhaust passage 11 is also provided in the machine body 1 and is communicated with the air frying burner and is used for exhausting air from the air frying burner to the outside; and,

[0051] A steam generating system, the steam generating system comprises a water tank 12 and a steam generator 2 arranged on the machine body 1, a water heat dissipation component is provided between the water tank 12 and the steam generator 2, and the water heat dissipation component is arranged at the exhaust passage 11; the water inlet end of the water heat dissipation component is connected to the water tank 12, and the water outlet end of the water heat dissipation component is connected to the steam generator 2.

[0052] In some embodiments, the drainage end of the water heat dissipation component is provided with a three-way valve 15 and a water pump, the three interfaces of the three-way valve 15 are respectively connected to the water heat dissipation component, the water tank 12 and the steam generator 2, and the water pump is arranged between the water heat dissipation component and the water tank 12. Specifically, the water heat dissipation component is connected to the water tank 12 through the first pipe 7, the three interfaces of the three-way valve 15 are respectively provided with a second pipe 8, a third pipe 9 and a fourth pipe 10, the second pipe 8 is connected to the water heat dissipation component, the third pipe 9 is connected to the water tank 12, and the fourth pipe 10 is connected to the steam generator 2, and the water pump is arranged on the second pipe 8 or the fourth pipe 10. When the steam generator 2 is working, the three-way valve 15 cuts off the third pipe 9, and the water in the water heat dissipation component flows into the steam generator 2 through the second pipe 8 and the fourth pipe 10; when the steam generator 2 is not working, the three-way valve 15 cuts off the fourth pipe 10, and the water pump works to pump the water in the water heat dissipation component into the water tank 12 through the second pipe 8 and the third pipe 9.

[0053] In some embodiments, Figure 4 As shown, the steam generator 2 includes a water tank 21 and a heating tube 22 arranged below the water tank 21. The water tank 21 can be arranged at the bottom of the cooking cavity. The heating tube 22 heats the water in the water tank 21 into water vapor. The water vapor is blown onto the food along with the hot air to replenish the water to the food, thereby achieving tender baking.

[0054] In some embodiments, Figures 1 to 3 As shown, in order to make the water heat dissipation component have a better heat dissipation effect, the water heat dissipation component includes a water box 14, and the water box 14 is located in the exhaust channel 11. When the hot air is discharged from the exhaust channel 11 to the outside, it contacts the surface of the water box 14, thereby heating the water in the water box 14, and heat conduction occurs, so that the temperature of the wind discharged after the heat is dissipated by the water box 14 is lower. The water box 14 can be specifically set as a square water box 14.

[0055] In some embodiments, Figure 2 As shown, different from the above scheme, a plurality of heat sinks 141 are provided on the outer wall of the water box 14, and a heat dissipation gap is provided between each two adjacent heat sinks 141. The plurality of heat sinks 141 are used to increase the contact area between the water box 14 and the hot air in the exhaust passage 11. After the contact area is increased, the efficiency of heat conduction is higher, thereby achieving a better heat dissipation effect. Specifically, when the exhaust passage 11 is located at the rear side of the machine body 1 and exhausts air backward, the extension direction of the heat sinks 141 located on the upper and lower left and right side walls of the water box 14 is set to extend from front to rear, so that the direction of the heat dissipation gap is consistent with the direction of the exhaust passage 11, which is conducive to the smooth discharge of hot air.

[0056] In some embodiments, in order to achieve a better heat dissipation effect, the heat sink 141 located on the upper side wall of the water box 14 extends from the surface of the water box 14 to the upper side wall in the exhaust channel 11;

[0057] The heat sink 141 located on the lower side wall of the water box 14 extends from the surface of the water box 14 to the lower side wall in the exhaust passage 11;

[0058] The heat sink 141 located on the left side wall of the water box 14 extends from the surface of the water box 14 to the left side wall of the exhaust passage 11;

[0059] The heat sink 141 located on the right side wall of the water box 14 extends from the surface of the water box 14 to the right side wall of the exhaust passage 11 .

[0060] In order to improve the heat dissipation effect, the heat sink 141 can be configured to be hollow, and its inner cavity can be filled with water, thereby improving the heat dissipation effect.

[0061] In some embodiments, in order to further increase the contact area between the water box 14 and the hot air in the exhaust channel 11, different from the above scheme, at least one heat dissipation channel is provided in the middle of the water box 14, and the extension direction of the heat dissipation channel is consistent with the extension direction of the exhaust channel 11, so that the hot air can be discharged smoothly from the heat dissipation channel;

[0062] When there are two or more heat dissipation channels, all the heat dissipation channels are arranged from top to bottom or from left to right. The cross-section of the heat dissipation channel can be square, circular, etc. The heat sink 141 is combined with the setting of the heat dissipation channel so that the hot air discharged through the exhaust channel 11 has a larger contact area with the water box 14, the efficiency of heat conduction is higher, and the heat dissipation effect is better.

[0063] In some embodiments, Figure 5 and Figure 6 As shown, the water heat dissipation assembly includes a curved water pipe 13, and the curved water pipe increases the contact area with the hot air in the exhaust channel 11;

[0064] Specifically, the curved water pipe 13 is curved in an S-shape or a serpentine shape from the upper side to the lower side of the exhaust passage 11;

[0065] Alternatively, the curved water pipe 13 is arranged to be curved in an S-shape or a serpentine shape from the left side to the right side of the exhaust passage 11;

[0066] Alternatively, the curved water pipe 13 is arranged to be spirally bent in a plurality of circles from the air inlet end to the air outlet end of the exhaust passage 11;

[0067] Alternatively, the curved water pipes 13 are arranged in parallel in a plurality of circles from the air inlet end to the air outlet end of the exhaust passage 11. A certain distance is provided between two adjacent circles, thereby increasing the contact area with the hot air in the exhaust passage 11 and facilitating the hot air to be discharged from the distance.

[0068] In some embodiments, in order to make the heat dissipation efficiency of the water heat dissipation component higher, a cold water chamber and a hot water chamber are provided in the water tank 12; the water inlet end of the water heat dissipation component is connected to the drainage end of the cold water chamber; the drainage end of the water heat dissipation component is connected to the water inlet end of the hot water chamber through the three-way valve 15. The hot water chamber can also be arranged to be connected to the steam generator 2 through a pipeline, so that when the steam generator 2 is working, the water in the hot water chamber can be added to the steam generator 2. The cold water chamber and the hot water chamber can be separated by a partition so that mixing does not occur. When the water heat dissipation component is working, the cold water chamber continuously adds cold water with a lower temperature to the water heat dissipation component. After the cold water with a lower temperature enters the water heat dissipation component, it is heated by hot air, and then the water with a higher temperature is discharged into the hot water chamber, so that the water heat dissipation component is continuously added with cold water, and the heat dissipation effect is better.

[0069] In some embodiments, Figure 1 , Figure 3 , Figure 4 and Figure 7 As shown, there are two cooking cavities, namely an upper cooking cavity 6 located at the upper side of the machine body 1 and a lower cooking cavity 4 located at the lower side of the machine body 1; there are two air frying burners, namely an upper air frying burner 5 for heating the upper cooking cavity 6 and a lower air frying burner 3 for heating the lower cooking cavity 4;

Specifically, an exhaust communication pipe 41 extending upward is provided on the upper side of the lower cooking cavity 4 , and the exhaust communication pipe 41 communicates with the lower hot air exhaust port 523 and the lower cooking cavity 4 .

A through hole for the first pipe 7 and the second pipe 8 to pass through is provided in the exhaust passage 11, so that the first pipe 7 and the second pipe 8 can pass through.

[0073] Working principle description:

[0074] When working, the water in the water tank 12 flows into the water heat dissipation component. When the hot air from the air fryer burner is blown out through the exhaust channel 11, it interacts with the water heat dissipation component, and the heat is absorbed by the water heat dissipation component, so that the wind temperature when discharged is relatively low. After being heated by the hot air, the water in the water heat dissipation component rises in temperature, and then flows into the steam generator 2 to be heated into steam. The steam generator 2 directly heats the water with a higher temperature, thereby saving energy consumption. When the steam generator 2 is not working, the water in the water heat dissipation component flows back into the water tank 12, so that the water tank 12 can continuously replenish cold water to the water heat dissipation component, so that the water heat dissipation component can always exert a high heat dissipation efficiency.
