Wherein each cell in the matrix of cells comprises an emitter (E-pole) 11, a collector (C-pole) 12 and a base (B-pole) 13. The emitting electrodes 11 of the photoelectric cells 10 in the same column in the photoelectric cell matrix are connected to the first ends of the same resistor in the first resistor set, the emitting electrodes 11 of the photoelectric cells 10 in different columns are respectively connected to the first ends of different resistors in the first resistor set, and the first ends of the resistors in the first resistor set are connected to the controller.

Fig. 3A to fig. 3D are schematic diagrams illustrating an exemplary photoelectric display panel of the present invention being shielded by a light shielding object. As shown in fig. 3A to 3D, the optoelectronic gesture control apparatus of this embodiment may further include a sensing panel 20, and the matrix of photocells is embedded in the sensing panel 20. The induction panel is used for fixing the appearance of the photoelectric tube matrix and can be in a regular shape or an irregular shape. The optoelectronic gesture control apparatus of this embodiment may further include a case panel 30, and the sensing panel is embedded in the case panel 30.

The embodiment 2 of the utility model provides a water heater, this water heater includes above-mentioned photoelectricity gesture controlling means.

Fig. 4 is a control flowchart of the optoelectronic gesture control apparatus shown in fig. 1 according to an example of the present invention.

As shown in fig. 4, in step S410, the photo cell matrix is divided into gesture recognition areas. A split zone function may be defined, for example, the left portion, the middle portion and the right portion of the sensing panel 20 in fig. 3D may be respectively used as a gesture recognition zone.

In step S420, when it is detected that the photocell in the gesture recognition area changes from the on state to the off state, it is recognized that the gesture recognition area is shielded from light.

As shown in fig. 1, 2 and 5, the photoelectric tube is generally used in a state where the base (B electrode) is open, and a voltage is applied between two terminals of the emitter (E electrode) and the collector (C electrode), and in this state, when light is incident on the surface of the base, the visible light shown in fig. 2 irradiates the photoelectric tube, and at this time, the base of the photoelectric tube is internally caused to generate a photoelectric effect as shown in fig. 5, and a current is generated, so that the photoelectric tube is turned on. Therefore, the first ends of the resistors R5-R10 in the first resistor set shown in fig. 1 detect voltages, and thus, which portion of the photocells is turned on can be determined. In the embodiment, the operation is reversed, all the photocells are turned on at first, as shown in fig. 6A, and then are shielded by the light-shielding object 40 shown in fig. 6B, as shown in fig. 3A to 3D, part of the photocells are shielded by the light-shielding object 4, and at this time, the photocells shielded by the light-shielding object 40 shown in fig. 3A to 3D cannot generate current due to loss of the irradiation of the visible light, so that the photocells are turned off. The shade 40 is, for example, a hand of a user.

In step S430, the gesture type is determined according to the position change condition and the light shielding duration of the light shielded gesture recognition area on the photocell matrix. As an alternative embodiment, the position of the gesture recognition area can be determined by the coordinates of the photoelectric tube in the gesture recognition area. The coordinates of the photocell can be represented by the row number and the column number of the photocell in the photoelectric matrix. The change of the photo-electric tube from the on-state to the off-state may be determined by a change of a voltage of an emitter of the photo-electric tube from a high level to a low level. The gesture types may include at least one of the following types: a gesture recognition area is continuously shielded for more than a preset time; the light shielding is changed from the first gesture recognition area to the second gesture recognition area adjacent to the first gesture recognition area. Specifically, gesture types may include motion gestures from left to right, right to left, top to bottom, bottom to top, and long dwell gestures, among others. In addition, different gesture recognition areas are shaded for a duration longer than a preset duration and can correspond to the same gesture type, so that the same gesture function is realized; and the gesture can also correspond to different gesture types, so that different gesture functions are respectively realized.

As the shade 40 shown in fig. 3A to 3D moves, the controller (MCU) may detect the coordinates of the cut-off photocell, so that the controller may judge that the shade 40 moves from left to right, thereby determining the corresponding gesture type. On the contrary, if the shade 40 moves as shown in fig. 3A to 3D, the controller may determine that the shade 40 moves from right to left, thereby determining the corresponding gesture type.

The working state of the photoelectric tube forms coordinates defined by a controller (MCU), and the controller calculates a gesture motion track through the coordinates. Still taking the example in fig. 1 as an example, all the photocells are in the conducting state at first. As shown in fig. 1, H1 to H4, L1 to L6 are connected to a controller, the controller will define a 6 × 4 matrix, in which the coordinates of the photocell Q1 are defined as Q1(L1, H1), the coordinates of the photocell Q2 are defined as Q2(L2, H1), the coordinates of the photocell Q3 are defined as Q3(L3, H1), and the coordinates of the photocell Q4 are defined as Q4(L4, H1) … …, and the coordinates of the photocell Q24 are defined as Q24(L6, H4). In this example, L1 refers to high, L1 refers to low; h1 indicates high level, H1 indicates low level, and so on, L2, L3 … … L6, H2, H3, H4 indicate high level; l2, L3 … … L6, H2, H3, H4 indicate low. When the photocell Q1 is shielded by a shade, the photocell Q1 is detected in the controller (MCU) as a change (-L1, H1), at which time the controller knows that the photocell Q1 is shielded.

If the photocell Q1 is shielded first, then the photocell Q2 is shielded, and then the photocell Q3 is shielded, the controller (MCU) detects that the coordinate change of the photocell is:

Q1(L1，H1)，Q2(L2，H1)，Q3(L3，H1)

Q1(～L1，H1)，Q2(L2，H1)，Q3(L3，H1)

Q1(L1，H1)，Q2(～L2，H1)，Q3(L3，H1)

Q1(L1，H1)，Q2(L2，H1)，Q3(～L3，H1)

Q1(L1，H1)，Q2(L2，H1)，Q3(L3，H1)

according to the change of the coordinates, the controller can judge that the shade moves from left to right.

For example, as shown in fig. 7, the shade shades the photocell Q1, the controller (MCU) detects the coordinates of the photocell Q1 and obtains the coordinate change from Q1(L1, H1) to Q1 (-L1, H1), if the shade of the photocell Q1 exceeds the preset time period T to be defined as the first gesture type corresponding to the first gesture function, the controller executes the first gesture function for detecting the photocell Q1 (-L1, H1) exceeds the preset time period T.

The control flow of the optoelectronic gesture control apparatus of this example may further include, after step S430, the steps of: and determining a function corresponding to the gesture type and executing the function corresponding to the gesture type.

The utility model discloses photoelectricity gesture controlling means and water heater can not be to sending visible light and invisible light outward when using, have reduced light pollution, have improved with natural harmonious degree. At night, the photoelectric tube is completely closed, and the power consumption is reduced. The photoelectric tube panel is used for realizing the gesture function, and an infrared gesture module is not needed. The gesture control instruction can be output only by simple matrix operation without complex algorithm, and meanwhile, the recognition efficiency is high, the accuracy is high, and the gesture positioning is accurate.
