[0022] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described in combination with the embodiments below. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] At present, the control panel of the range hood equipment is usually a mechanical button control panel or a touch screen control panel installed at a high place of the range hood. The control panel has low sensitivity and is not easy to clean when there is oil on the user's hands, resulting in a poor user experience. In addition, when the user operates the range hood, if the control panel is installed at a low position, the user is prone to burns during operation. If the control panel is installed at a low position, it is inconvenient for users with shorter height to operate. Therefore, the relevant technology proposes that an upwardly projected control panel can be set on the stove surface. However, the control panel cannot be moved in the above scheme, which affects the user experience. In addition, the temperature of the stove surface varies greatly and the temperature difference is large, which can easily affect the service life of the control panel and cause operational failure. Based on this, the projection interaction device provided by the present invention can adjust the projection mode and projection position of the range hood control panel according to the user position and the working status of the stove, thereby significantly improving the convenience and safety of the user's operation of the range hood, and improving the user experience.

[0024] To facilitate understanding of this embodiment, a projection interaction device disclosed in an embodiment of the utility model is first introduced in detail.

[0025] See also Figure 1 The schematic diagram of the structure of a projection interaction device is shown. The utility model provides a projection interaction device, including: a sensor detection module and a projection interaction module, the sensor detection module and the projection interaction module are connected, the sensor detection module is used to obtain stove information and target object information, the projection interaction module is used to receive the stove information and target object information, and project the range hood projection interaction control panel, wherein the stove information includes: stove position and stove surface temperature, the target object information includes: target object position, target object height, and target object gesture information. In one embodiment, the stove information and target object information obtained by the sensor detection module can be used for projection by the projection interaction module, and the user can also switch the working state of the projection interaction module, that is, when the user is at a relatively far distance, the interactive operation panel is projected through air imaging, and projection interaction is performed according to the user's static gesture image or dynamic gesture information obtained by the camera. When the user is cooking in front of the stove, the interactive operation panel can be projected through infrared dot matrix in the low temperature area of ​​the stove surface, thereby avoiding the problem of poor air projection effect caused by the high temperature of the stove.

[0026] The above-mentioned projection interaction device and system provided by the embodiment of the utility model can adjust the projection mode and projection position of the range hood control panel according to the user's position and the working status of the stove, thereby significantly improving the convenience and safety of the user's control of the range hood and enhancing the user experience.

Finally, the first range hood projection interaction control panel is projected in the low temperature area of ​​the preset projection area of ​​the stove surface. In addition, the first range hood projection interaction control panel is composed of an infrared dot matrix, which is used to sense the touch information of the target object on the first range hood projection interaction control panel. When the user's hand touches any area on the first range hood projection interaction control panel, the pulse signal of the infrared dot matrix at that position changes, so that the user's control operation on the range hood can be determined and executed.

The projection interaction module also includes: a second projector, which is respectively connected to the infrared sensor 000 and the camera, and is used to project the second range hood projection interaction control panel through the projection beam 002 in the fog curtain in front of the target object to obtain the projection interaction interface 003, so that the target object can execute the control operation of the second range hood projection interaction control panel through gesture information, wherein the button 004 can be a virtual button on the projection interaction interface 003.
