After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

1. Through the design of the air curtain cooker introduced in the present invention, the air outlet is higher than the cooker, so that even if there is water or dust on the cooker that is easy to move, or in an environment with complicated airflow, it will not be blocked. into the air outlet, thereby preventing foreign matter from being brought into the air curtain device or the stove. Ensure equipment cleanliness to a great extent.

2. According to the air curtain cooker introduced in the present invention, the air outlet is designed to be higher than the upper surface of the cooktop so that the air curtain is formed at a position higher than the cooktop. Since the stove is also provided with a heating device, this design can reduce the influence of the air curtain on the flame of the heating device. For example, when there are other kitchen utensils on the cooktop, the air curtain may change direction under the cover of the kitchen utensils, but the design of the present invention makes even if this happens, the affected air curtain airflow will flow upwards and Instead of flowing along the surface of the stove, it ensures the combustion stability of the heating device.

3. With the air curtain cooker introduced in the present invention, the air outlet is designed so that the air outlet can be ring-shaped around the cooktop, providing greater flexibility for the location of the air outlet. In addition, the air outlet part is a boss-shaped structure, which supports the air outlet of the air curtain on multiple surfaces to ensure the structural stability of the air outlet. It can be seen that other items may be placed on the stove, so the structural performance of the air outlet is strengthened, so that it has good anti-deformation ability, and ensures that the air outlet can maintain a stable air supply capacity and stability in the environment of airflow vibration during the generation of the air curtain. wind direction positioning capability. Moreover, the orientation design of the air outlet can ensure that the airflow of the air curtain will not be blown onto the user, so as to avoid causing discomfort to the user.

4. With the air curtain cooker introduced in the present invention, the design of the air outlet as a strip-shaped hole structure can ensure the continuity of the air curtain generated by the air curtain device, and ensure that the generated air curtain will not have the problem of partial lack of airflow. If the air outlet in the air curtain process is designed as a multi-point arrangement structure, the position between the points is the position where the air pressure is at the bottom because there is no gas outflow, which will cause uneven air pressure throughout the air curtain and cause turbulent flow. Affects the maintenance of the direction of the air curtain. Moreover, the design of the hole-shaped air outlet depends on the fully wrapped structure of the air outlet at least on two sides. It is this structure that can provide good support for the air outlet, so that the structure of the strip-shaped air outlet can be realized. .

5. With the air curtain cooker introduced in the present invention, the partial structure of the air curtain device is adjusted to form a cooker. Then there is no connection position (gap, gully) between the air curtain device and the stove, but a completely integrated structure. Reduce the possibility of foreign matter accumulating on the cooktop, and further reduce the possibility of foreign matter entering the air outlet of the air curtain from the structural design.

6. With the air curtain cooker introduced in the present invention, a cooperative relationship is established between the fan device and the control system, so that the fan device can adjust its own working mode according to the working conditions of the control system. When the control system increases the firepower, the air curtain fan device will increase the output of the air volume and improve the efficiency of the air curtain. When the control system reduces the firepower, the fan device of the air curtain will reduce the output of the air volume and reduce the efficiency of the air curtain. Realize automatic control of air curtain efficiency and status.

7. With the air curtain cooker introduced in the present invention, the design of the air direction adjusting part is added, so that the direction of the air curtain can be guided by the air direction adjusting part. Since the air curtain regulator is a movable part during the use of the equipment, it can be installed inside the air outlet to effectively prevent it from being polluted by oil, and it can be protected by the cavity formed by the air outlet, and it can also avoid wind direction The movement of the adjusting element affects the user. Furthermore, the wind direction adjusting member can realize the function of closing the air outlet in at least one position, and then block the air outlet when the equipment does not need the air curtain function, so as to further ensure that foreign objects will not enter this position.

8. With the air curtain cooker introduced in the present invention, the design of the wind direction control part is added, and the wind direction adjustment part can adjust the wind direction under the action of the wind direction control part, and the user can control the wind direction of the air curtain through the adjustment of the wind direction control part. Since in actual use, the position and amount of oily fumes are closely related to the shape and size of the pot, the user can adjust the wind direction of the air curtain according to the specific situation during use.

The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
