On the other hand, the UI interface of the air conditioner and the range hood is complex, and the user experience is poor. When cooking, the user needs to press buttons, which is slightly inconvenient. In addition, the UI interface of the air conditioner and the range hood of the existing refrigeration range hood is complex, and the user experience is poor. There is no gesture control operation.

[0039] The present invention is further described in detail below with reference to the accompanying drawings.

[0040] like Figures 1 to 6 As shown, the display switch structure of this embodiment includes a display light board bracket 1, a display light board assembly 2 and a light board cover 3. The display light board assembly 2 is mounted on the display light board bracket 1 and fixed by the light board cover 3. The display light board assembly 2 includes a light board lower cover 21, a PCB board 22, a light board upper cover 23, a display film 24, a sealing ring 29 and a light emitter 210. Among them, the PCB board 22 is mounted between the light board lower cover 21 and the light board upper cover 23, and a sealing ring 29 is installed between the light board lower cover 21 and the light board upper cover 23. The light board lower cover 21 and the light board upper cover 23 are sealed by squeezing the sealing ring 29. The light emitter 210 is mounted on the PCB board 22, and the light board upper cover 23 is provided with a shading hole 231 corresponding to the light emitter 210, and the shading hole 231 surrounds the corresponding light emitter 210. The display film 24 covers and is installed on the front side of the light board upper cover 23. A glass panel 211 is installed on the front side of the display film 24. After the light-emitting body 210 passes through the display film 24, the corresponding icon lights up to realize light-transmitting display.

[0041] A first gesture control sensor group for identifying the range hood function and a second gesture control sensor group for identifying the cooling function are installed on the PCB board 22, and through holes 27 corresponding to the first gesture control sensor group and the second gesture control sensor group are opened on the upper cover 23 of the light board and the display film 24. The sensing heads of the first gesture control sensor group and the second gesture control sensor group pass through the through holes 27, and a metal plate 28 is installed on the sensing heads. The metal plate 28 is used to detect whether the user touches the sensor to avoid accidental touch when scrubbing the range hood.

[0042] In this embodiment, the first gesture control sensor group includes a left sensor 251 and a right sensor 252 . The second gesture control sensor group is disposed between the left sensor 251 and the right sensor 252 . The second gesture control sensor group includes an upper sensor 261 and a lower sensor 262 .

[0043] The refrigeration type range hood of this embodiment comprises a casing 5, which comprises an upper box body 51 and a lower box body 52. ​​The range hood module 6, the compressor 7, the heat dissipation module 8 and the internal module 9 are all installed in the upper box body 51. The compressor 7, the heat dissipation module 8 and the internal module 9 are connected through the refrigerant pipeline 10. An air inlet 53 is provided on the lower box body 52, and an air-conditioning outlet 50 is provided on the front of the lower box body 52. ​​The air outlet of the internal module 9 is connected to the air-conditioning outlet 50. The display switch structure of this embodiment is installed on the front of the casing 5 and is located below and adjacent to the air-conditioning outlet 50.

[0044] like Figure 7 As shown, the control method of the refrigeration range hood of this embodiment includes the following control logic:

[0045] S1, start;

[0046] S2, determining whether there is a signal input from the first gesture control sensor group and the second gesture control sensor group;

[0047] If yes, read the time values ​​T11 and T12 when the first gesture control sensor group is triggered and the time values ​​T21 and T22 when the second gesture control sensor group is triggered, and read the current input values ​​I11 and I12 when the first gesture control sensor group is triggered and the current input values ​​I21 and I22 when the second gesture control sensor group is triggered;

[0048] S3, △T1=|T11-T12|, △T2=|T21-T22|, determine whether △T1>T01 or △T1>T02 is true;

[0049] If established, proceed to step S4;

[0050] If not, keep waiting;

[0051] S4, determine whether I11>0 or I12>0 or I22>0 or I22>0 is true,

[0052] If yes, proceed to step S5;

[0053] If not, keep on standby;

[0054] S5, determine whether △T1>T01 is true,

[0055] If established, proceed to step S6;

[0056] If not, the cooling function is started;

[0057] S6, determine whether △T2>T02 is true,

[0058] If established, it may be triggered by mistake, so keep on standby;

[0059] If not, start the range hood in automatic mode.

[0060] It can be seen from the above control process that when the user needs to start the range hood's oil fume suction function, the user waves his hand to the left or right, and by identifying the input signal of the first gesture control sensor group, the range hood is turned on. The difference between the present invention and the traditional range hood gesture recognition is that the present invention has a second gesture control sensor group, and the user controls the start of the refrigeration function. When the user waves to start the range hood function, the second gesture control sensor group will also input a signal, and it is necessary to determine whether to turn on the refrigeration function. Only when the user waves up or down in the center of the display panel, the range hood will be controlled to turn on the refrigeration function. At the same time, in order to avoid the user accidentally touching the surface of the range hood to turn it on, it is necessary to detect the surface current.

[0061] The present invention detects the sensor trigger time, the first gesture control sensor group input values ​​are T11 and T12, the second gesture control sensor group input values ​​are T21 and T22. The first gesture control sensor group input current values ​​are I11 and I12, the second gesture control sensor group input current values ​​are I21 and I22.

[0062] In the present invention, T0 is used to determine whether the user waves or is triggered by other reasons, and its range is 0.5s≤T0≤1.5s. When it is less than 0.5 seconds, it is possible that the user waves horizontally or vertically, triggering another set of sensors to cause signal feedback, so it needs to be greater than or equal to 0.5 seconds. When T0>1.5s, it is likely that the user walked past the range hood and detected the signal, so it needs to be excluded. The optimal value is T01=1s, T02=0.7s.

[0063] When it is determined that △T1 and △T2 are both greater than T0, there is a high probability that the user triggered it unconsciously, so the device needs to remain in standby mode.

[0064] The principle and method of turning off the oil fume suction function and the refrigeration function are the same as those of turning them on, so they will not be described in detail here.
