Detailed Description
The invention is described in further detail below with reference to the accompanying examples.
The false touch prevention touch panel in this embodiment can be applied to various electrical appliances with touch panels, and in this embodiment, the application of the false touch prevention touch panel in the range hood is taken as an example, and detailed description is performed on the range hood and the false touch prevention touch panel.
As shown in fig. 1, the range hood in this embodiment includes a range hood body, a controller disposed in the range hood, and a touch panel disposed on the range hood body for preventing accidental touch. The false touch prevention touch panel is arranged on the front panel of the range hood body.
The anti-false touch panel comprises a panel 1, a touch key 2 and at least two brightness sensors 3, wherein the touch key 2 and the brightness sensors 3 are embedded in the panel 1, and the touch key 2 and the brightness sensors 3 are electrically connected with a controller.
The luminance sensors 3 are located on the outer periphery of the touch key 2, so that the number of the luminance sensors 3 is specifically determined according to the shape and the area of the distribution area of the touch key 2, and when the distribution range of the touch key 2 is circular, the luminance sensors 3 are distributed along the circumferential direction of the distribution range of the touch key 2. If the distribution range of the touch key 2 is rectangular, the luminance sensors 3 are horizontally distributed along the upper and lower sides of the touch key 2, and may also be vertically distributed on both sides of the distribution range of the touch key 2.
The touch keys 2 in the range hood are generally arranged in a straight line shape along the horizontal direction, and the brightness sensors 3 are respectively and uniformly arranged above and below the distribution area of the touch keys 2. In the present embodiment, the number of the luminance sensors 3 is even, specifically 6, three luminance sensors 3 are respectively arranged in a line shape in the horizontal direction above and below the distribution area of the touch key 2, and the luminance sensor 3 located above the distribution area of the touch key 2 and the luminance sensor 3 located below the distribution area of the touch key 2 are aligned in the vertical direction.
The touch key 2 is generally circular or square, and assuming that the diameter of the touch key 2 or the diameter of a circumscribed circle is d, the shortest distance b between the luminance sensor 3 and each touch key 2 is not less than 3 d. Therefore, the misjudgment that whether the detection result of the brightness sensor 3 is triggered by mistake or not is influenced by shielding the brightness sensor 3 when the normal touch key 2 is operated can be effectively avoided. Certainly, the condition that the shortest distance between the brightness sensor 3 and each touch key 2 is too large to identify false triggering is avoided, and b is less than or equal to 4 d.
The width of a normal hand is 50-100 mm, and the length of the normal hand is 120-200 mm. The height of the panel 1 of the anti-false touch panel is usually between 40 and 80mm in the market. On this basis, the distance between two adjacent luminance sensors 3 in the horizontal direction is c, 50mm ≦ c ≦ 100mm, e.g., c ≦ 80 mm. Therefore, when the user performs wiping cleaning on the anti-false touch panel, the shielding signals of the two brightness sensors 3 can be detected more easily and simultaneously, and the condition that the user performs wiping cleaning can be judged more quickly. The distance between two brightness sensors 3 in the vertical direction is a, 40mm ≦ a ≦ 80mm, e.g., 60 mm. If the height of the panel 1 of the anti-false touch panel is high enough, a can be more than or equal to 80mm and less than or equal to 200mm, therefore, a can be selected within the range that a is more than or equal to 40mm and less than or equal to 200mm, the distance a is set, meanwhile, the shielding signals of the two brightness sensors 3 can be conveniently detected, and the condition that a user is wiping and cleaning can be judged more quickly.
The touch panel touch prevention method comprises the following steps: in a state where the touch panel is on standby:
s1, acquiring the detection signal of each luminance sensor 3, and normally, each luminance sensor 3 detects the luminance signal according to the sampling period; the brightness sensor 3 in this embodiment may adopt an infrared sensor, and a higher triggering condition of the infrared sensor may be set in this embodiment, that is, the brightness sensor 3 may be triggered to send a signal to the controller only when a larger amount of infrared rays need to be received, that is, a shielding object completely approaches the panel 1 of the anti-false touch panel and completely shields the brightness sensor 3, so that the detection accuracy of the shielding signal of the brightness sensor 3 may be improved;
s2, if the shielding signal of the luminance sensor 3 is not detected, it indicates that the luminance sensor 3 is not shielded by foreign matter, the user is not performing a trigger operation to affect the luminance sensor 3, and the user is not performing a wiping cleaning operation to shield the luminance sensor 3, at this time, if the user operates the touch key 2, the controller controls to respond to the trigger operation of the touch key 2;
when the shielding signal of one brightness sensor 3 is detected, due to the aforementioned distance between the brightness sensor 3 and the touch key 2, the user usually does not cause two brightness sensors 3 to detect shielding information at the same time when operating the touch key 2, therefore, it may be that the user covers one brightness sensor 3 to detect the shielding signal of one brightness sensor 3 when operating the touch key 2, or that the user shields one brightness sensor 3 during wiping the touch panel to detect the shielding signal of one brightness sensor 3, and at this time, since it cannot be determined whether the user is operating the touch key 2 or performing wiping cleaning, then, the touch key 2 may be controlled to lock for T seconds to prohibit triggering response, at this time, the locking time T for the touch key 2 is short, T is greater than or equal to 0.3 and less than or equal to 1 in this embodiment, for example, T is greater than or equal to 0.5 seconds;
after the touch key 2 is locked for T seconds, judging the specific conditions according to the detection signals of the brightness sensors 3 detected in real time;
if the shielding signal of the brightness sensor 3 is not detected after the touch key 2 is locked for T seconds, the lock of the touch key 2 can be released, so that the applied electric appliance can respond to the trigger operation of the touch key 2; this process is an operation process for unintentionally shielding the luminance sensor 3 when the user is performing an operation of the touch key 2;
if the touch key 2 detects the shielding signal of at least one brightness sensor 3 after being locked for T seconds, the corresponding work flow is correspondingly carried out;
when the shielding signal of more than one brightness sensor 3 is detected, it is determined that the user is performing the cleaning work of wiping the touch panel, because the user usually holds the cleaning cloth with his hand to cover the touch panel and then performs the cleaning work during the cleaning process of the touch panel, the cleaning cloth covers the touch panel in a large area during the cleaning process, and then more than two brightness sensors 3 are easily covered, so that the shielding signal of more than one brightness sensor 3 is detected;
at the moment, the touch key 2 is controlled to be locked for T1 seconds to prohibit triggering response;
t1 > T, where T1 may be a preset time for wiping the touch panel, that is, a general user can complete the cleaning work of wiping the touch panel within the time duration of T1, that is, the user is considered to perform the cleaning work within the preset time range for wiping the touch panel, at this time, the touch key 2 is locked to prevent the touch key 2 from being triggered, the user does not trigger a standby electrical appliance to work during the wiping process, and the cleaning work is very convenient. When the locking time of the touch key 2 reaches T1, the locking of the touch key 2 is released, and the operation can still be performed according to the foregoing process. In the embodiment, T1 is more than or equal to 180 and less than or equal to 600, such as T1 is 300 seconds.
S3, after the shielding signal of the brightness sensor 3 is detected, timing the continuous time of the shielding signal of the brightness sensor 3, judging whether the time length of the shielding signal of the brightness sensor 3 reaches T0, if not, returning to S1 to continue working, if not, judging that the brightness sensor 3 is shielded by foreign matters, and controlling to alarm that the brightness sensor 3 is shielded by the foreign matters, wherein T0 is the threshold time for wiping the touch panel. If the luminance sensor 3 mask signal is not detected within the time range of T0, the continuous time during which the luminance sensor 3 mask signal is detected is cleared.
The anti-false touch panel, the range hood and the anti-touch method of the touch panel can reduce the probability of false triggering of the touch key 2 in the wiping and cleaning process, and greatly improve the convenience of cleaning the electric appliance.
