[0030] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully conveyed to those skilled in the art.

[0031] Figure 1 This is a schematic diagram of the structure of the photoelectric gesture control device provided in Example 1 of the present invention. Figure 2 The internal structure diagram of a photoelectric tube provided as an example of the present invention. Figure 1 and Figure 2 As shown. The photoelectric gesture control device provided in this embodiment includes a photoelectric tube matrix composed of at least one photoelectric tube 10, a controller (MCU), a first resistor set and a second resistor set. Among them, each photoelectric tube in the photoelectric tube matrix includes an emitter (E pole) 11, a collector (C pole) 12 and a base (B pole) 13. The emitter 11 of each photoelectric tube 10 in the same column of the photoelectric tube matrix is ​​connected to the first end of the same resistor in the first resistor set, and the emitters 11 of each photoelectric tube 10 in different columns are respectively connected to the first ends of different resistors in the first resistor set, and the first ends of each resistor in the first resistor set are connected to the controller. The collector 12 of each photoelectric tube 10 in the same row of the photoelectric tube matrix is ​​connected to the first end of the same resistor in the second resistor set, and the collector 12 of each photoelectric tube 10 in different rows is respectively connected to the first ends of different resistors in the second resistor set, and the second end of each resistor in the second resistor set is connected to the controller. The photoelectric tube 10 is a material designed and manufactured based on the photoelectric effect, that is, light generates electricity. The photoelectric tube described in this article is a phototransistor. When there is light, the phototransistor is turned on, and when there is no light, the phototransistor is turned off. When the photoelectric tube 10 is irradiated with visible light, it sends an electrical signal to the controller, and when the photoelectric tube 10 is shielded from light, it sends this information to the controller.

[0032] In this embodiment, the second end of each resistor in the first resistor set can be grounded. The collector 12 of each photoelectric tube 10 in the photoelectric tube matrix can be connected to the input voltage. The photoelectric tube 10 can also include a photoelectric tube protection layer 14.

[0033] Figure 1 This is merely an example of a photoelectric tube matrix to illustrate the structure of a photoelectric gesture control device, and is not intended to limit the number of photoelectric tubes on the photoelectric tube matrix or the shape of the photoelectric tube matrix.

[0034] Figure 3A-3D Schematic diagrams of different parts of an optoelectronic display panel shielded by a shading object provided as an example of the present invention. Figure 3A-3D As shown, the photoelectric gesture control device of this embodiment may further include a sensing panel 20, and the photoelectric tube matrix is ​​embedded in the sensing panel 20. The sensing panel is used to fix the shape of the photoelectric tube matrix, and may be a regular shape or an irregular shape. The photoelectric gesture control device of this embodiment may further include a housing panel 30, and the sensing panel is embedded in the housing panel 30.

[0035] Embodiment 2 of the present invention provides a water heater, which includes the above-mentioned photoelectric gesture control device.

[0036] Figure 4This is a flow chart of the control method of the above-mentioned photoelectric gesture control device provided in Embodiment 3 of the present invention.

[0037] like Figure 4 As shown, in step S410, the photoelectric tube matrix is ​​divided into various gesture recognition areas. The regional functions can be specified, such as Figure 3D The left part, the middle part and the right part of the middle sensing panel 20 can be used as a gesture recognition area respectively.

[0038] In step S420, when it is detected that the photoelectric tube 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.

[0039] like Figure 1 , Figure 2 and Figure 5 As shown in the figure, the phototube is generally used in the open state of the base (B pole), and the voltage is applied between the emitter (E pole) and the collector (C pole). In this state, when light is incident on the surface of the base, Figure 2 The visible light shown in the figure illuminates the photoelectric tube. At this time, the internal Figure 5 As shown, the photoelectric effect occurs at the base of the phototube, generating current and turning on the phototube. Figure 1 The voltage is detected at the first end of the resistors R5 to R10 in the first resistor set, and then it can be determined which part of the photoelectric tubes are turned on. This embodiment is a reverse operation, which makes all the photoelectric tubes turned on at the beginning, such as Fig. 6A As shown, it is then Figure 6B The light shielding material 40 shown blocks visible light. FIG. 3A to FIG. 3D The light shielding object 4 shown in the figure shields part of the photoelectric tube, which is FIG. 3A to FIG. 3D The photoelectric tube shielded by the shading object 40 shown in the figure loses the irradiation of visible light, so that the base of the photoelectric tube cannot generate current, so that the photoelectric tube is cut off. The shading object 40 is, for example, a user's hand.

[0040] In step S430, the gesture type is determined according to the position change of the gesture recognition area on the photoelectric tube matrix and the duration of the shading. As an optional implementation, 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 photoelectric tube can be represented by the row number and column number of the photoelectric tube in the photoelectric tube matrix. The photoelectric tube can be determined to change from the on state to the off state by the voltage of the emitter of the photoelectric tube changing from a high level to a low level. The gesture type can include at least one of the following types: a gesture recognition area is continuously shielded for more than a preset time; the first gesture recognition area is shielded and the second gesture recognition area adjacent to the first gesture recognition area is shielded. Specifically, the gesture type can include motion gestures from left to right, from right to left, from top to bottom, from bottom to top, and long-term stay gestures. In addition, different gesture recognition areas are shielded for more than a preset time, which can correspond to the same gesture type, thereby realizing the same gesture function; or can correspond to different gesture types, thereby realizing different gesture functions respectively.

[0041] As FIG. 3A to FIG. 3D The controller (MCU) can detect the coordinates of the photoelectric tube that is cut off, so the controller can determine that the light shielding object 40 moves from left to right, thereby determining the corresponding gesture type. FIG. 3A to FIG. 3D From the movement shown, the controller can determine that the shading object 40 moves from right to left, thereby determining the corresponding gesture type.

[0042] The working state of the photoelectric tube forms the coordinates defined by the controller (MCU), and the controller calculates the gesture movement trajectory through the coordinates. Figure 1 Take the example in the figure, at the beginning all photoelectric tubes are in the on state. Figure 1 As shown, H1 to H4, L1 to L6 are all connected to the controller, and the controller will define a 6 × 4 matrix, in which the coordinates of the phototube Q1 are defined as Q1 (L1, H1), the coordinates of the phototube Q2 are defined as Q2 (L2, H1), the coordinates of the phototube Q3 are defined as Q3 (L3, H1), the coordinates of the phototube Q4 are defined as Q4 (L4, H1)... The coordinates of the phototube Q24 are defined as Q24 (L6, H4). In this example, L1 refers to a high level, ~L1 refers to a low level; H1 refers to a high level, ~H1 refers to a low level, and so on, L2, L3...L6, H2, H3, H4 refer to a high level; ~L2, ~L3...~L6, ~H2, ~H3, ~H4 refer to a low level. When the phototube Q1 is blocked by a light blocking object, the phototube Q1 is detected in the controller (MCU) as (~L1, H1), and at this time, the controller knows that the phototube Q1 is blocked.

[0043] If the phototube Q1 is shielded first, then the phototube Q2, and finally the phototube Q3, the controller (MCU) detects the coordinate changes of the phototubes as follows:

[0044] Q1 (L1, H1), Q2 (L2, H1), Q3 (L3, H1)

[0045] Q1 (~L1, H1), Q2 (L2, H1), Q3 (L3, H1)

[0046] Q1 (L1, H1), Q2 (~L2, H1), Q3 (L3, H1)

[0047] Q1 (L1, H1), Q2 (L2, H1), Q3 (~L3, H1)

[0048] Q1 (L1, H1), Q2 (L2, H1), Q3 (L3, H1)

[0049] Based on the change in coordinates, the controller can determine that the shading object moves from left to right.

[0050] For example, Figure 7 As shown, the shading object blocks the phototube Q1, and the controller (MCU) detects the coordinates of the phototube Q1 and obtains the coordinate change, that is, from Q1 (L1, H1) to Q1 (~L1, H1). If the phototube Q1 is blocked for more than the preset time T, it is defined as the first gesture type, corresponding to the first gesture function. Then, in the controller, if it is detected that the phototube Q1 (~L1, H1) exceeds the preset time T, the first gesture function is executed.

[0051] The control method of the photoelectric gesture control device of this embodiment may further include, after step S430, the steps of: determining a function corresponding to the gesture type and executing the function corresponding to the gesture type.

[0052] The photoelectric gesture control device and method and the water heater of the embodiment of the present invention do not emit visible light and invisible light when in use, which reduces light pollution and improves harmony with nature. At night, all photoelectric tubes will be turned off to reduce power consumption. The gesture function is realized by using a photoelectric tube panel, and there is no need to use an infrared gesture module. No complicated algorithms are required, only simple matrix operations are needed to output gesture control instructions, and at the same time, the recognition efficiency is high, the accuracy is high, and the gesture positioning is accurate.
