Referring to Figure 1, the touch control module 25 mainly includes a microprocessor control circuit 25! and a light-emitting device control circuit 252. The microprocessor control circuit (5) is composed of a power supply circuit, a microprocessor and its associated circuits, and the microprocessor can be a single-chip microcomputer of the type CY8(10)45. The greening control circuit 252 can be formed by a shift register, a light-emitting device driving chip and other electronic components. The model of the shift register can be 74hc595d, and the model of the light-emitting device driving chip can be DS2〇〇3cmx. . Each of the first touch sensor 211, the second touch sensor 214, and the first touch sensor 216 are monitored by the microprocessor control circuit 251, that is, 10 M419989, as shown in FIG. 12 and FIG. The sensing signal (corresponding to the capacitance value of the touch sensor in this embodiment) is compared with a set threshold value: '乂determining the switching state of the function button corresponding to each touch sensor, The switch status signal is sent to the external interface to drive the washing machine to perform the corresponding operation. In addition, the microprocessor control circuit 251 can also receive a light-emitting device (LED) display state control signal 'from the external interface and convert it into a drive signal for transmission to the light-emitting device control circuit 252. The illuminating device control circuit 252 receives the signal sent by the microprocessor control circuit 251 to drive each corresponding illuminating device into different lighting states according to the signal logic: full light, half light, annihilation, so as to be displayed on the main panel 丨Different working conditions. In actual application, when the operator's finger approaches the first touch display area 111 on the main panel 1 from above, the sensing of the first touch sensor 211 below the first touch display area 111 The signal (in this embodiment, the capacitance value corresponding to the touch sensor) is gradually increased and the sensing signal is transmitted to the touch control circuit 25, and the touch control circuit 25 monitors the first touch. When the capacitance value of the sensor 211 exceeds the set threshold (the finger has touched or is very close to the surface of the first touch display area 111 at this time), the touch control circuit 25 can correspondingly control the first touch. The first illuminating device 212 controlling the side edge of the sensor 211 is changed from the initial semi-bright illuminating state to the fully-illuminated illuminating state, thereby changing the backlight state of the function display pattern on the main panel 丨 first touch display area ill, and simultaneously The operation information informs the washing machine to perform the corresponding operation. Specifically, in the embodiment, the physical quantity of the 11 M419989 of the sub-display unit 118 is more than the second touch sensor 214 corresponding to the combined touch area 114 of the ring. The physical quantity (eight in total) 'When the operator's finger moves to a certain area in the combined touch area 114, the capacitance values of several second touch sensors 214 in the vicinity of the finger change The sensing signal is transmitted to the touch control circuit 25, and the touch control circuit 25 performs a total calculation on the sensing signals, and calculates the adjacent combination of the most intense changes of the induced signals by the inductive detection algorithm to determine the finger The touch position is specifically above the second touch sensor 214, and may further be specific to whether the touch position is above or at the middle of the boundary portion of the second touch sensor 214. And then controlling the second illuminating device 215 under the sub-display unit 118 corresponding to the touch position in the combined display area 115 from the first un-selected first illuminating state (in the embodiment) Corresponding to the semi-bright illumination state) changing to the selected second illumination state (in this embodiment_ corresponding to the full-bright illumination state), while the other second illumination device 215 below the unselected sub-display unit 118 remains Maintaining a half π illuminating state; this design is such that each physical second touch sensor 214 can correspond to two corresponding sub-display units 118 in the combined display area 115 (each sub-display unit 118 corresponds to - The specific touch mode is such that the eight second touch sensors in the combined touch area 114 can correspond to the sixteen sub-display units ι 8 in the combined display area 115. Thus, the second touch sensing stomach can be lowered. The arrangement density of 214 reduces the difficulty of manufacturing and manufacturing costs. Of course, other inductive detection algorithms can also be used to make the first touch sensing benefit 214 and the sub-discovery HQ 2 Fen + /, 卞 不 兀 兀 118 establish a non-like mapping relationship, for example: the initial value can be Any one of the sub-display units 118 is fully illuminated 12 M419989 is not displayed, and when the finger slides over a second touch sensor 2i4, it automatically switches to the next-to-next adjacent sub-display unit 118. The previous sub-display unit 118 returns to the semi-bright state. In this way, when the operator's finger moves along the combined touch area 114_, the second light-emitting device 2 of the selected corresponding sub-display unit ι 8 in the combined display area H5 will be fully illuminated in turn and not selected. The second illumination device 215 of the sub-display unit 118 is sequentially restored to the original semi-bright state, and this operation interface allows the operator to switch and select in a variety of different (four) laundry modes. Finally, when the operator's finger falls on the function performing touch display area ι 6 , the second touch sensor 216 can sense the proximity of the operator's finger to generate an inductive signal and transmit the sensing signal to the touch control circuit. 25, in order to control the first light-emitting device 217 to be fully illuminated, while the washing machine can start cleaning according to the selected laundry mode. This cool operation interface is quite flexible, which is beneficial to provide a better user experience and thus improve the home appliance. The texture 'operation is also extremely convenient. Referring to Figures 2-8, the main circuit module 3 includes a second circuit board 31, a cable connector 32, and a display module 33 disposed in parallel with the first circuit board 21. The second circuit board 31 is disposed under the notch 213 of the first circuit board 21 to form a height difference with the first circuit board 21 so as to be spatially spaced apart by a distance. The second circuit board 3 1 can pass through the connector. (not shown) is electrically connected to the first circuit board 21. In the embodiment, the touch control circuit 25 is disposed on the second circuit board 31. The first circuit board 21 and the second circuit board 31 are separated, and the first touch sensors can be spatially disposed. 211, the second touch sensor 214 (13 M419989 shown in FIG. 9 and 10) and the third touch sensor 216 are isolated from the touch control circuit 25, so that the touch on the second circuit board 31 can be reduced. The electromagnetic radiation emitted by the control circuit 25 and the other power components interferes with the first touch sensor 211, the second touch sensor 214, and the third touch sensor 216 on the first circuit board 21, thereby preventing The capacitance value of the touch sensor fluctuates up and down to generate an erroneous sensing signal, which further causes the touch control circuit 25 to perform a misjudgment operation. One end of the cable connector 32 can be directly soldered to the second circuit board 31, and the other end can be matched with other circuits in the washing machine, such as the motor control board in the washing machine, thereby capturing the touch control circuit 25. The operation signal is sent to the main control circuit of the washing machine to perform the operation control of the motor. Referring to Figures 7 and 8, the display module 33 is mounted below the display window 112 of the base 11 of the main panel 1. The display module 33 can be a led lighting module or an LCD lighting module to provide an indication of the working state of the washing machine by displaying a plurality of different lighting patterns. Preferably, the display module 33 is juxtaposed on the side of the first circuit board 21 at the notch 213. Preferably, the second circuit board 31 is directly soldered to the bottom surface of the display module 33, and the electronic components constituting the touch control circuit 25 are disposed. The structure of the second circuit board 31 facing away from the bottom surface of the main panel 1 and the touch control circuit 25 on the second circuit board 31 and the touch sensor of the first circuit board 21 are designed to be further away from each other can be further reduced. The touch control circuit 25 interferes with the touch sensor. On the other hand, by combining the display module 33 having a higher display density and the illuminating touch module 2 having a lower display function and a lower display density, it is advantageous to improve the key layout of the touch panel and reduce the cost. In summary, the touch panel of the present invention can scatter the first illuminating device 212, the second illuminating device 215, and the third illuminating device 217 downward by providing the reflecting member 23 under the light guide member 22 M419989. The light from the bottom surface of the light member 22 is reflected back to the light guide 22, and is further emitted upward from the display pattern on the main panel i, so that the first light-emitting device 212, the first light-emitting device 215, and the second light-emitting device can be added without increasing the light-emitting device. Under the premise of 217 power consumption, the brightness of the display pattern of the first touch display area 111, the combined display area 丨丨5, and the function execution touch display area 116 is improved, which is beneficial to improving the visual effect and energy saving of the touch panel.
