Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1-5, an air fryer with a projection control device comprises a fryer main body 1, a fryer basket 2 capable of opening or closing relative to the fryer main body 1, and an electric control assembly arranged in the fryer main body 1, wherein the fryer main body 1 is also provided with a projection device 3 and an information collection sensor assembly 4 which are electrically connected with the electric control assembly;

the projection device 3 can project a user virtual control interface 5 outwards, and the user virtual control interface 5 comprises a plurality of independent functional areas 6;

the information collection sensor assembly 4 can identify the independent functional area 6 corresponding to the hand of the user and feed back the independent functional area to the electronic control assembly.

Specifically, projection arrangement 3 include PCB control panel 7, set up LED lamp pearl 8, collimating lens 9 and MLA microlens 10 on PCB control panel 7 in proper order, PCB control panel 7 with automatically controlled subassembly electricity be connected. During the use, PCB control panel 7 signals, and LED lamp pearl 8 starts and send light, and light realizes the light path through collimating lens 9 and corrects, finally throws outside through MLA microlens 10 again, forms effective, clear, high brightness's user virtual control interface 5.

Specifically, the information collecting sensor assembly 4 is a TOF sensor. When in use, based on TOF (time of flight) laser ranging technology: the TOF is an absolute distance detection technology, that is, a sensor emits a debugged near-infrared light, which is reflected after encountering an object, and the sensor converts the distance of a shot scene by calculating the time difference or phase difference between light emission and reflection to generate depth information, so as to judge the independent functional area 6 to be selected by a user.

A single TOF sensor is limited by a mounting position and a monitoring angle, and has large errors. Preferably, the number of the TOF sensors is 3, the TOF sensors are distributed on the left side, the middle part and the right side of the fryer body 1, and the distances between the adjacent TOF sensors are the same. By adopting the preferred scheme, the 3 TOF sensors are cooperatively matched to judge the selected independent functional area 6 more accurately, so that the probability of misjudgment is reduced.

In this embodiment, the fryer body 1 is further provided with a wake-up sensor 11, and the wake-up sensor 11 is electrically connected with the electric control component. Preferably, the wake-up sensor 11 is an infrared sensor. That is, when the projection apparatus 3 needs to be used, the user needs to place the hand in the area that can be detected by the wake-up sensor 11, after the wake-up sensor 11 recognizes the user instruction, the projection apparatus 3 is waken up by the electronic control component, and then the projection apparatus 3 projects the user virtual control interface 5 outwards. Therefore, when the projector is not in operation, the off state of the projector 3 can be kept for a long time, the effects of energy conservation and environmental protection are achieved, and misoperation of children and the like is prevented.

If the projection distance of the projection device 3 is long, the effect of the screen is significantly reduced, and therefore, the projection is generally performed at a close position. On the other hand, a handle is arranged on the frying basket 2 for facilitating the taking out and putting in of the frying basket 2. However, the existence of the handle can cause interference to a projection picture, so that part of contents are projected on the handle, and normal use is influenced. In order to solve the above-mentioned defects, the handle has an avoidance section 14, and the projection device 3 is located directly above the avoidance section 14. Preferably, the handle comprises a left handle 12 and a right handle 13, the avoidance section 14 is located between the left handle 12 and the right handle 13, and the left handle 12 and the right handle 13 are in a shape of a straight line.

The air fryer is limited by different use scenes of different users, and a support for supporting the virtual control interface 5 of the users may be absent from the outside, so that the air fryer cannot be normally used. In order to solve the above-mentioned drawbacks, the fryer body 1 has a receiving slot 15 at the bottom thereof, a curtain 16 is slidably disposed in the receiving slot 15, and the curtain 16 can be drawn outwards relative to the fryer body 1, so that the user virtual control interface 5 projected by the projection device 3 is formed on the curtain 16.

In the utility model, the fryer body 1 comprises a heating component and a fan component (not shown in the figure), the heating component and the fan component are respectively and electrically connected with the electric control component, and a user selects an independent functional area 6 in a user virtual control interface 5 to realize different control effects on the heating component and the fan component.

The working principle of the utility model is as follows: the user is close to fryer main part 1, places the hand to awaken sensor 11 department, stays a period of time in order to let awaken sensor 11 detect, and then projection arrangement 3 starts to project user virtual control interface 5 to supports such as desktop or curtain board 16, and then the user selects independent function area 6 in user virtual control interface 5 according to the demand of self, and information collection sensor subassembly 4 discerns independent function area 6 that user's hand corresponds and feeds back to automatically controlled subassembly immediately, starts corresponding function finally.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, changes and equivalent structural changes made to the above embodiments according to the technical spirit of the present invention still fall within the protection scope of the technical solution of the present invention.
