[0039]

[0040] ​Specifically, the air outlet end of the air outlet pipe 13 is connected to the air outlet 141, and the air outlet pipe 13 is rotatably connected to the airflow cavity 12, for example, the air outlet pipe 13 can be connected to the airflow cavity 12 through a bearing or other rotating type structure, wherein the airflow cavity 12 is a fixed end, and the air outlet pipe 13 is a movable end, and the rotation axis of the air outlet pipe 13 can be vertical, that is, the air outlet end of the air outlet pipe 13 can rotate around the vertical circumference, that is, under the driving action of the airflow driving element 124, the airflow in the airflow cavity 12 can be sent into the air outlet pipe 13, and the rotation of the air outlet pipe 13 can realize the rotary air outlet, and the air outlet end of the air outlet pipe 13 extends into the cooking cavity 11 to blow air towards the cooking cavity 11. Wherein the rotation of the air outlet pipe 13 can be driven by airflow or motor.

[0041] As shown in Figure 1 and Figure 2 The upper surface of the machine body 1 is provided with a control panel 19, and the user controls the operation of the cooking equipment 100 by operating the control panel 19. The machine body 1 is also provided with a heating structure. After the airflow driving element 124 and the heating structure work, the air outlet end of the air outlet pipe 13 rotates around the rotation axis of the air outlet pipe 13 relative to the cooking cavity 11, so that the air outlet pipe 13 rotates and sprays air towards the cooking cavity 11, so that the food is heated by the hot air in a circumferential circle. Its air supply direction is uniform, and the wind power is concentrated, which improves the utilization efficiency of the hot air. By setting the rotary air supply, the hot air can be blown to the food more uniformly, so that the food is heated faster and more uniformly, which improves the cooking effect of the food and improves the user's experience.

[0042] Wherein, the air outlet pipe 13 and / or the air guide pipe 14 can also be in communication with the steam pipe, that is, the air outlet pipe 13 can rotatably deliver steam towards the cooking cavity 11. In this way, the steam can be used to cook food, and the rotary delivery of steam can improve the flow speed of the steam in the cooking cavity 11, thereby improving the steaming effect and improving the cooking function of the cooking equipment 100.

[0043] According to the cooking equipment 100 of the embodiment of the utility model, the air outlet pipe 13 is rotatably connected to the air outlet end of the airflow cavity 12, which can realize the rotary sweeping air outlet of the air outlet pipe 13, so that the air direction towards the cooking cavity 11 is uniform and the wind power is concentrated, thereby improving the cooking effect of the food and improving the use performance of the cooking equipment 100.

[0044] In some embodiments, the machine body 1 is provided with an air guide pipe 14, the airflow cavity 12 includes an air guide cavity 121 formed in the air guide pipe 14, and the end of the air guide pipe 14 is provided with an air outlet 141, and the air outlet pipe 13 is rotatably connected to the end of the air guide pipe 14.

[0045] Specifically, the air guide pipe 14 is used for circulating hot air, is located at the upper side of the cooking cavity 11, extends in the horizontal direction, and forms an air guide cavity 121 in the air guide pipe 14. The air flow cavity 12 includes the air guide cavity 121. As shown in Figure 1 The air guide pipe 14 forms an air outlet 141 at the air outlet end thereof for air outlet of the air guide pipe 14, and the air outlet end of the air guide pipe 14 is rotationally connected to the air inlet end of the air outlet pipe 13, so that the air guide pipe 14 is communicated with the air outlet pipe 13 through the air outlet 141. The air guide pipe 14 is a fixed end, and the air outlet pipe 13 can rotate around the air outlet 141 of the air guide pipe 14 in the circumferential direction. In this way, the hot air in the air guide pipe 14 enters the air outlet pipe 13 through the air outlet 141, and is then outlet from the air outlet end of the air outlet pipe 13. After the air outlet pipe 13 rotates relative to the air guide pipe 14, the air outlet pipe 13 can rotate to blow air towards the cooking cavity 11. The overall structure is simple, the air outlet effect is good, and the food can be uniformly heated.

[0046] In some embodiments, the cooking device 100 further includes a connecting bearing 15, which includes a bearing inner ring 151, a bearing outer ring 152, and rolling elements 153 connected between the bearing inner ring 151 and the bearing outer ring 152. One of the air outlet pipe 13 and the air guide pipe 14 is connected to the bearing outer ring 152, and the other is connected to the bearing inner ring 151. The axis direction of the connecting bearing 15 is parallel to the up-down direction.

[0047] That is, the air outlet pipe 13 can be connected to the bearing outer ring 152, and the air guide pipe 14 can be connected to the bearing inner ring 151, or the air outlet pipe 13 can be connected to the bearing inner ring 151, and the air guide pipe 14 can be connected to the bearing outer ring 152. Both of these two arrangements can achieve the connection of the air guide pipe 14 and the air outlet pipe 13 through the connecting bearing 15, and the relative rotation of the two.

[0048] Specifically, the connecting bearing 15 is used to rotationally connect the air outlet pipe 13 and the air guide pipe 14. The connecting bearing 15 includes a bearing inner ring 151, a bearing outer ring 152, and rolling elements 153 connected between the bearing inner ring 151 and the bearing outer ring 152. As shown in Figure 4 and Figure 5 In this embodiment, the connecting bearing 15 is arranged between the air guide pipe 14 and the air outlet pipe 13. The air outlet pipe 13 is connected to the bearing outer ring 152, and the air guide pipe 14 is connected to the bearing inner ring 151. In this way, the inner diameter of the air outlet pipe 13 is greater than the outer diameter of the air guide pipe 14. The air outlet pipe 13 is rotationally connected to the outer periphery of the air guide pipe 14 through the connecting bearing 15. Compared with the arrangement in which the bearing outer ring 152 of the connecting bearing 15 is connected to the air guide pipe 14 and the bearing inner ring 151 is connected to the air outlet pipe 13, the area of the connecting bearing 15 that is in contact with high-temperature hot air can be reduced, and the service life of the connecting bearing 15 can be improved. The connecting bearing 15 can be a ball bearing.

[0049] The axial direction of the connecting bearing 15 is parallel to the up-down direction, and the axial direction of the connecting bearing 15 is the rotation axis of the air outlet pipe 13, and the rotation axis of the air outlet pipe 13 is parallel to the up-down direction, so that the air outlet pipe 13 can rotate relative to the air guide pipe 14 along the up-down direction, and the air outlet pipe 13 can rotate to blow air to the cooking cavity 11 in the circumferential direction, and the angle of the air outlet pipe 13 can be ensured to be consistent, thereby improving the heating effect on the food, and the connecting bearing 15 is provided to make the rotation of the air outlet pipe 13 more smooth and stable, and to ensure that the air outlet is more stable.

[0050] In some embodiments, the end of the air guide pipe 14 is provided with a first mounting surface 142 and a first limiting surface 143, and the air inlet end of the air outlet pipe 13 is provided with a second mounting surface 131 and a second limiting surface 132, the first mounting surface 142 and the second mounting surface 131 are spaced apart and oppositely distributed along the horizontal direction, and the first limiting surface 143 and the second limiting surface 132 are parallel and distributed in the vertical direction.

[0051] The bearing inner ring 151 and the bearing outer ring 152 are located between the first mounting surface 142 and the second mounting surface 131, the first limiting surface 143 is axially limited to one end of the bearing inner ring 151, and one end of the bearing outer ring 152 is limited and supported on the second limiting surface 132.

[0052] Specifically, as shown in Figure 5 In actual design, the air outlet end of the air guide pipe 14 is bent inward to form the first limiting surface 143 and the first mounting surface 142, wherein the first mounting surface 142 extends in the vertical direction, the first limiting surface 143 is located at the upper end of the first mounting surface 142, and the first limiting surface 143 and the first mounting surface 142 are both distributed in the circumferential direction, and the air inlet end of the air outlet pipe 13 is bent outward to form the second limiting surface 132 and the second mounting surface 131, wherein the second mounting surface 131 extends in the vertical direction, the second limiting surface 132 is located at the lower end of the second mounting surface 131, and the second limiting surface 132 and the second mounting surface 131 are both distributed in the circumferential direction, and the first mounting surface 142 and the second mounting surface 131 are spaced apart and oppositely distributed along the horizontal direction, the outer diameter of the first mounting surface 142 is smaller than the inner diameter of the second mounting surface 131, the first limiting surface 143 is parallel to the second limiting surface 132 and is distributed in the vertical direction, the first limiting surface 143 is located above the second limiting surface 132 and is located on the inner side of the second limiting surface 132 in the circumferential direction.

[0053] Further, the bearing inner ring 151 is mounted on the outer side of the first mounting surface 142, and the first limiting surface 143 limits the upper end of the bearing inner ring 151, thereby achieving the upper limiting of the connecting bearing 15, and the bearing outer ring 152 is mounted on the inner side of the second mounting surface 131, and the second limiting surface 132 limits the lower end of the bearing outer ring 152, thereby achieving the limiting and supporting of the connecting bearing 15. In this way, the connecting bearing 15 is mounted between the first mounting surface 142 and the second mounting surface 131, and is axially limited by the first limiting surface 143 and the second limiting surface 132, thereby achieving the rotation connection of the air outlet pipeline 13 and the air guide pipeline 14, and the connection is reliable and easy to realize the rotation of the air outlet pipeline 13 relative to the air guide pipeline 14.

[0054] In some embodiments, the cooking device 100 further comprises a connecting shaft sleeve, the end of the air outlet pipeline 13 and the end of the air guide pipeline 14 are inserted and matched, and the connecting shaft sleeve is mounted and supported between the end of the air outlet pipeline 13 and the end of the air guide pipeline 14.

[0055] Specifically, the connecting shaft sleeve and the connecting bearing 15 have the same effect, both of which can achieve the relative rotation of the air outlet pipeline 13 and the air guide pipeline 14. The end of the air outlet pipeline 13 and the end of the air guide pipeline 14 both extend in the up-down direction, and the air outlet pipeline 13 and the air guide pipeline 14 are inserted and matched in the up-down direction and connected through the connecting shaft sleeve. The connecting shaft sleeve and the connecting bearing 15 have similar mounting methods. The connecting shaft sleeve includes a shaft sleeve inner ring and a shaft sleeve outer ring. The shaft sleeve inner ring can be mounted and supported on the end of the air guide pipeline 14, and the shaft sleeve outer ring can be mounted and supported on the end of the air outlet pipeline 13, thereby achieving the connection of the air outlet pipeline 13 and the air guide pipeline 14, and the air outlet pipeline 13 rotates relative to the air guide pipeline 14 through the connecting shaft sleeve. The mounting method is simple, can realize the rotation function, and has low cost.

[0056] In some embodiments, the air outlet direction of the air outlet 141 forms an angle with the axis direction of the air outlet pipeline 13, and the air outlet pipeline 13 is adapted to rotate under the action of the wind force at the air outlet 141.

[0057] That is, the air outlet direction of the air outlet 141 and the axis direction of the air outlet pipeline 13 are not arranged in a straight line, but the directions of the two exist an angle, and the force can be exerted on the connecting bearing 15 through the wind force at the air outlet 141.

[0058] Thus, when the air outlet direction of the air outlet 141 is inconsistent with the axial direction of the air outlet duct 13, the airflow at the air outlet 141 can flow out along the air outlet duct 13, at the same time, the airflow at the air outlet 141 can exert a pushing force on the connecting bearing 15, and the air outlet duct 13 can rotate freely in the horizontal direction, that is, the air outlet duct 13 can rotate relative to the air guide duct 14, so that the air outlet duct 13 can rotate and blow air towards the cooking cavity 11, the air blowing direction is more consistent, and the air blowing precision is improved.

[0059] The air outlet direction of the air outlet 141 and the axial direction of the air outlet duct 13 form an angle, the size and direction of the angle are not limited, and the setting mode is various, which can be set according to actual space requirements.

[0060] In some embodiments, the axial direction of the air outlet duct 13 forms an angle less than 90° with the horizontal direction, that is, the axial direction of the air outlet duct 13 is not parallel to the horizontal direction, that is, the axial direction of the air outlet duct 13 intersects with the horizontal direction, and the angle setting mode is various and can be flexibly selected.

[0061] In this way, through the above setting, the airflow at the air outlet 141 can flow out along the air outlet duct 13, and the airflow direction forms an angle with the horizontal direction, so that the airflow can form a pushing force on the air outlet duct 13, and the air outlet duct 13 can be pushed to rotate relative to the air outlet 141 to realize the rotation of the air outlet duct 13 to blow air to the cooking cavity 11.

[0062] And / or, the axial direction of the air outlet duct 13 forms an angle less than 90° with the vertical direction, that is, the axial direction of the air outlet duct 13 is not parallel to the vertical direction, that is, the axial direction of the air outlet duct 13 intersects with the vertical direction, and the angle setting mode is various and can be flexibly selected.

[0063] In this way, through the above setting, the airflow at the air outlet 141 can flow out along the air outlet duct 13, and the airflow direction forms an angle with the vertical direction, so that the airflow can form a pushing force on the air outlet duct 13, and the air outlet duct 13 can be pushed to rotate relative to the air outlet 141 to realize the rotation of the air outlet duct 13 to blow air to the cooking cavity 11.

[0064] And through the above two angle setting modes, the rotation driving force of the air outlet duct 13 can be realized, and the setting mode is various and the use effect is good.

[0065] In some embodiments, the airflow cavity 12 further comprises a heating member 123, and the airflow driving member 124 is adapted to drive the airflow to flow through the heating member 123 and then flow to the air outlet duct 13.

[0066] Specifically, the heating member 123 is configured to heat air, wherein the heating member 123 can be configured as a heating pipe, the heating pipe is detachably connected in the air flow cavity 12, the heating member 123 is located between the air inlet 122 and the air outlet 141, and the air flow driving member 124 and the heating member 123 are sequentially distributed in the air flow cavity 12 along the flow direction of the air flow. Thus, under the driving action of the air flow driving member 124, a negative pressure is formed in the air flow cavity 12, air outside the machine body 1 is sucked into the air flow cavity 12 from the air inlet 122, the air passes through the heating member 123 to be heated, and the high-temperature hot air after being heated flows into the air outlet pipeline 13 from the air flow cavity 12. The air outlet end of the air outlet pipeline 13 is rotatable relative to the air flow cavity 14, so that the air flow can be rotated to flow to the cooking cavity 11, thereby achieving uniform heating of the food.

[0067] In some embodiments, the air outlet pipeline 13 is arranged at the top of the cooking cavity 11, and the air outlet pipeline 13 comprises at least two air outlet pipeline segments connected in sequence, and adjacent two air outlet pipeline segments are connected in a bent manner, wherein the extension direction of the air outlet pipeline segment in which the air outlet end is formed forms an angle with the top wall and the side wall of the cooking cavity 11.

[0068] Specifically, the air outlet pipeline 13 is arranged at the top of the cooking cavity 11 to send hot air from the top of the cooking cavity 11 into the cooking cavity 11. The air outlet pipeline 13 comprises at least two air outlet pipeline segments connected in sequence, such as two, three, four, etc., and adjacent two air outlet pipeline segments are connected in a bent manner, so as to change the flow direction of the air flow, so that the air flow flows in different directions. The extension direction of the air outlet pipeline segment in which the air outlet end is located forms an angle with the top wall and the side wall of the cooking cavity 11, that is, the air outlet pipeline segment in which the air outlet end is located is arranged in an inclined manner, and the top wall and the side wall of the cooking cavity 11 can be perpendicular, the top wall is distributed along the horizontal direction, and the side wall is distributed along the vertical direction. The extension direction of the air outlet pipeline segment forms an angle with the vertical direction and the horizontal direction.

[0069] Therefore, the extension direction of the air outlet pipeline segment in which the air outlet end is located forms an angle with the top wall of the cooking cavity 11, so as to form a reverse thrust after the hot air is sprayed from the air outlet pipeline 13, so that the air outlet pipeline 13 can be rotated, and the extension direction of the air outlet pipeline segment in which the air outlet end is located forms an angle with the side wall of the cooking cavity 11, so as to spray the hot air from the top of the cooking cavity 11 in an inclined direction downward. In this way, the air outlet pipeline 13 can be arranged to rotate and incline to send air to the cooking cavity 11, so that the air sending direction is more consistent, and the air sending precision is improved.

[0070] In some embodiments, an arc-shaped transition segment 136 is connected between adjacent two air outlet pipeline segments, that is, the arc-shaped transition segment 136 is arranged at the connection between adjacent two air outlet pipeline segments. The arc-shaped transition segment 136 can be configured in different structures. In actual design, for example, Figures 7-10As shown, the arc transition section 136 can be constructed as a quarter-circle arc segment, which can realize the vertical connection of the two air outlet pipe segments. Alternatively, the arc transition section 136 can be an irregular structure, specifically, the bending direction of this arc transition section 136 forms an angle with both the horizontal and vertical directions. That is, the arc transition section 136 is used as a transition structure for non-right-angle connection. In this way, the two air outlet pipe segments can be connected at an angle, and the two ends of the arc transition section 136 are smoothly connected to the two air outlet pipe segments respectively, making the connection of the two air outlet pipe segments more natural and smooth.

[0071] Therefore, setting the arc transition section 136 makes the connection and setting of multiple air outlet duct sections simpler and more convenient, and can change the direction of airflow and smoothly guide the airflow, reducing turbulence and eddies at the corner of the air outlet duct 13, thereby reducing resistance and pressure drop and increasing the airflow velocity.

[0072] In some embodiments, the air outlet duct 13 includes three air outlet sections, namely a first section 133, a second section 134 and a third section 135 connected in sequence, wherein the third section 135 forms an air outlet end, wherein the angle between the axial direction of the second section 134 and the axial direction of the third section 135 is α, and satisfies 60°≤α≤135°.

[0073] Specifically, such as Figure 7 As shown, in this embodiment, there are three air outlet pipe sections, namely the first section 133, the second section 134, and the third section 135. The second section 134 is bent and connected to the first section 133 and the third section 135 respectively. The first section 133, the second section 134, and the third section 135 are all constructed as cylindrical pipes. The first section 133 has an air inlet end, which is rotatably connected to the air outlet 141 of the air guide pipe 14. The third section 135 has an air outlet end and is open towards the cooking cavity 11. The bending angle between the first section 133 and the second section 134 is different from the bending angle between the second section 134 and the third section 135. The bending angle between the first section 133 and the second section 134 can be 90°. The axial direction of the third section 135 has an angle with both the vertical and horizontal directions.

[0074] like Figure 10 As shown, the axis of the second segment 134 is horizontal, and the axis of the third segment 135 forms an angle with the horizontal direction. Let this angle be α, which can be 60°, 90°, 135°, etc. By setting the angle between the axes of the second segment 134 and the third segment 135 to these values, hot air is ejected from the open end of the third segment 135 after passing through the second segment 134 and the arc-shaped transition section 136. The ejected hot air provides a certain amount of counter-force and allows the air outlet duct 13 to rotate freely in the horizontal direction, thus filling the cooking cavity 11 with hot air. Furthermore, the value of the angle α is not limited to that described in this embodiment and can be set according to actual airflow requirements, offering high flexibility.

[0075] In some embodiments, the angle between the axial direction of the first section 133 and the axial direction of the third section 135 is b, and 20°≤b≤70° is satisfied. Figure 8 Figure 9 As shown in FIGS. 13, 14, and 15, the axial direction of the first section 133 is the up-down direction, and the axial direction of the third section 135 forms an angle with the up-down direction, and the angle is b. The angle b can be 20°, 50°, 70°, etc. By setting the angle between the axial direction of the first section 133 and the axial direction of the third section 135 to the above values, the hot air can be sprayed from the third section 135 in a tangential and downward direction after passing through the first section 133, the arc-shaped transition section 136 of the front section, the second section 134, and the arc-shaped transition section 136 of the rear section, so that the air flow in the cooking cavity 11 is rolled to uniformly and quickly heat the food. The value of the angle b is not limited to the above values, and can be set according to the actual air direction and the rolling effect of the hot air.

[0076] Therefore, by setting the angle between the axial direction of the second section 134 and the axial direction of the third section 135 to 60°≤a≤135°, and the angle between the axial direction of the first section 133 and the axial direction of the third section 135 to 20°≤b≤70°, the air outlet duct 13 can be horizontally rotated by 360° by the air force, and the high-temperature hot air can be sprayed into the cooking cavity 11 at an angle, so that the hot air is rolled to uniformly and quickly heat the food, and the cooking effect is improved.

[0077] It should be noted that, when the third section 135 of the air outlet duct 13 is subjected to the air force, the air outlet duct 13 is rotated without dead angle in the horizontal plane, and as shown in FIGS. 13, 14, and 15, the air outlet duct 13 is rotated to three angles. Figure 1 Figure 3 Figure 4 Figure 6 It can be seen that, in the process of continuously discharging air, the air outlet duct 13 continuously rotates to supply air into the cooking cavity 11, so that the hot air in the cooking cavity 11 is more uniform and has the same air volume, the hot air is quickly rolled, the difference between the cooking effects of the upper surface and the lower surface of the food is reduced, and the cooking effect of the food is effectively improved.

[0078] In some embodiments, the first section 133 extends in the up-down direction, and the cooking cavity 11 is configured as a cylindrical cavity, the axis of the first section 133 coincides with the axis of the cooking cavity 11, and as shown in FIGS. 13, 14, and 15, the first section 133 can be a cylindrical duct extending in the up-down direction. Figure 7 Figure 1 Figure 4 Figure 6 ​​​​​​​As shown, the cooking cavity 11 can be configured as a cylindrical cavity, the first section 133 is arranged at the top of the cooking cavity 11, as shown Figure 1 As shown, and the first section 133 is located at the center of the cooking cavity 11, that is, the axis of the first section 133 coincides with the axis of the cooking cavity 11, so that after the air outlet pipe 13 is driven to rotate, the air outlet pipe 13 rotates around the axis of the cooking cavity 11, which can cover the entire cylindrical cooking cavity 11, and can uniformly heat the food.

[0079] Therefore, the above setting mode is simple and reasonable, which makes the air outlet pipe 13 blow air more uniformly in the cooking cavity 11, and the hot air gathering degree in the cooking cavity 11 is high, which is beneficial to improve the cooking effect of hot air on food.

[0080] In some embodiments, the air outlet direction of the air outlet pipe 13 is inclined relative to the axis of the air outlet pipe 13, and the air outlet pipe 13 is rotated under the action of the airflow, that is, by setting the air outlet direction of the air outlet pipe 13 to be inclined, the rotation of the air outlet pipe 13 can be realized under the thrust of the airflow, and the inclined air outlet direction can be rotated to incline the air outlet towards the cooking cavity 11.

[0081] Specifically, after the cooking device 100 works, the airflow driving member 124 and the heating member 123 work, the airflow driving member 124 drives the hot airflow to be sprayed from the inclined air outlet end of the air outlet pipe 13, and under the thrust of the high-speed hot airflow, the air outlet pipe 13 rotates relative to the cooking cavity 11, and rotates to spray air towards the cooking cavity 11, so that the food is heated by the hot air in a circumferential circle, which ensures that the air outlet direction is consistent and can directly flow to the food, thereby improving the heating efficiency and heating effect of the food and improving the user's use experience.

[0082] Therefore, the air outlet pipe 13 is rotated relative to the air guide pipe 14 by the action of the airflow, which can reasonably utilize resources, so that the driving structure of the air outlet pipe 13 is simpler, the air supply effect is better, and the cost is saved, and the use effect is good.

[0083] In other embodiments, the machine body 1 is provided with a rotary driving member connected with the air outlet pipe 13 and used to drive the air outlet pipe 13 to rotate, that is, the rotary driving member directly drives the air outlet pipe 13 to rotate, which can realize the automatic rotation of the air outlet pipe 13.

[0084] The rotating driving member can be a driving motor directly or indirectly connected with the air outlet pipeline 13. The rotating driving member transmits power to the air outlet pipeline 13 to drive the air outlet pipeline 13 to rotate relative to the air guide pipeline 14, so that the hot air flowing out of the air outlet pipeline 13 flows to the cooking cavity 11 in a circumferential diffusion manner, and the hot air is distributed in the cooking cavity 11 in a large area. The air outlet direction of the air outlet pipeline 13 is inclined towards the bottom of the cooking cavity 11, so that the hot air quickly flows to the food, improving the heating efficiency of the food and improving the cooking effect of the food.

[0085] Therefore, the rotating driving member drives the air outlet pipeline 13 to rotate relative to the air guide pipeline 14, so that the air outlet pipeline 13 actively rotates with good rotating effect, and the rotating driving mode of the air outlet pipeline 13 is various, which can be selectively set according to actual space requirements and heating requirements.

[0086] In some embodiments, the cooking device 100 further comprises a humidifying device in communication with the air outlet pipeline 13, and the humidifying device is adapted to deliver steam or water into the cooking cavity 11 through the air outlet pipeline 13.

[0087] In particular, during the cooking process, especially when baking or steaming food, the moisture on the surface of the food is easy to evaporate. The humidifying device can supply the lost moisture to the cooking cavity 11 in time through the air outlet pipeline 13, and maintaining a certain humidity helps to uniformly cook the food and avoid drying or excessive charring of the food surface. In addition, the humidifying device can be separately provided with a connecting pipeline connected with the cooking cavity 11, and can separately provide water and steam to the cooking cavity 11. In this way, the air outlet pipeline 13 can work separately to meet different cooking requirements.

[0088] In addition, for food that needs to be steamed, the humidifying device can provide the necessary water or steam environment to cook the food in steam to achieve the effect of steaming. In addition, appropriate humidity helps to control the temperature in the cooking cavity 11 to avoid local overheating. The humidifying device can increase the multifunctionality of the cooking device, so that it can not only bake and barbecue, but also steam, to meet different cooking requirements. Appropriate humidity control can improve the cooking efficiency and reduce the cooking time, thereby saving energy.

[0091] The projection of the visual window 101 and the projection of the heating element 123 and / or the projection of the airflow driving element 124 are distributed staggered along the up-down direction, that is, the projection of the visual window 101 can be distributed staggered along the up-down direction only with the projection of the heating element 123, or can be distributed staggered along the up-down direction only with the projection of the airflow driving element 124, or can be distributed staggered along the up-down direction with the projection of the heating element 123 and the projection of the airflow driving element 124. In this embodiment, the projection of the visual window 101 is distributed staggered along the up-down direction with the projection of the heating element 123 and the projection of the airflow driving element 124. When the cooking appliance 100 cooks food, the user can observe the food from the visual window 101, so as to avoid the heating element 123 and the airflow driving element 124 blocking the line of sight, ensure the observation integrity, and improve the use experience.
