Detailed Description
The following detailed description of specific embodiments of the invention refers to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative and explanatory of the invention and are not restrictive thereof.
The apparatus for a water dispenser according to the present invention will be described with reference to the accompanying drawings.
Fig. 1 is a block schematic diagram of a device for a water dispenser according to an embodiment of the present invention. Fig. 2 is a schematic perspective view of a device for a water dispenser according to an embodiment of the present invention. Fig. 3 is a schematic perspective view of a device for a water dispenser according to an embodiment of the present invention. As shown in fig. 1 to 3, in an embodiment of the present invention, a device 1 for a water dispenser is provided, which is capable of detecting whether an object placed by a user is a target water receiving container, controlling water to be discharged from the water dispenser in a case where it is determined that the object is the target water receiving container, so as to improve water discharging accuracy of the water dispenser, and prohibiting water to be discharged from the water dispenser 2 in a case where it is determined that the object is not the target water receiving container, so as to avoid water leakage or potential safety hazard of the water dispenser 2. The apparatus 1 for a water dispenser comprises an ultrasonic detector 113, at least one detection device 11 and a processor 12.
The ultrasonic detector 113 is configured to detect that an object is located in a water receiving table area of the water dispenser 2, generate a water receiving signal in response to detecting that the object is located in the water receiving table area, the at least one detection device 11 is configured to detect that the object enters the water receiving table detection area of the water dispenser 2, generate a detection signal in response to detecting that the object enters the water receiving table detection area, and the processor 12 is configured to receive the water receiving signal and the detection signal and judge whether the placed object is a target water receiving container, and control water outlet of the water dispenser 2 to improve accuracy of water outlet of the water dispenser 2 in the case that the object is determined to be the target water receiving container; and under the condition that the object is determined not to be the target water receiving container, the water outlet of the water dispenser 2 is forbidden, so that the water dispenser 2 is prevented from leaking water or generating potential safety hazards.
In one example, the ultrasonic detector 113 is disposed at the water outlet of the water dispenser 2 and emits ultrasonic waves toward the water outlet of the water dispenser 2 to detect whether an object is located in the water receiving platform area, that is, whether the object is located corresponding to the water outlet, so as to prevent the water from the water dispenser 2 from not falling into the target water receiving container accurately when the object is the target water receiving container and generating a water receiving signal when the object is located in the water receiving platform area. Specifically, when the position of the object corresponds to the water outlet, the ultrasonic detector 113 detects the height change of the water receiving table area according to the reflected sound wave, and at this time, it is determined that the object is located in the water receiving table area and generates a water receiving signal; when the position of the object does not correspond to the water outlet, the ultrasonic detector 113 detects that the height of the water receiving table area is unchanged according to the reflected sound wave, and at the moment, the object is determined not to be in the water receiving table area, and a water receiving signal cannot be generated.
In an embodiment of the present invention, at least one detection device 11 comprises an optical sensor, such as an infrared sensor 111, a TOF sensor 112, or the like.
In one example, by using various types of water cups, such as disposable water cups, tea cups, vacuum cups, etc., as the target water receiving containers, various types of interferents, such as spoons, chopsticks, etc., as the non-target water receiving containers, and the target water receiving container and the non-target water receiving container are successively placed in the water receiving platform area of the water dispenser 2 for experiment, the processor 12 detects that the accuracy of the object positioned in the water receiving platform area is 99% through the water receiving signal generated by the ultrasonic detector 113, detects that the accuracy of the placed target water receiving container is 99.5% through the detection signal, detects that the accuracy of the placed non-target water receiving container is 99.3%, the water dispenser 2 is controlled to discharge water only when the ultrasonic detector 113 detects that the target water receiving container is positioned in the water receiving platform area and detects that the put-in object is the target water receiving container. When the ultrasonic detector 113 detects that the target water receiving container is not in the water receiving platform area or the water receiving container is not placed in the water receiving platform area, the water dispenser 2 is controlled to prohibit water outlet, double detection is realized to control water outlet of the water dispenser 2, the water outlet accuracy of the water dispenser 2 is increased, and water leakage or potential safety hazard generation of the water dispenser 2 is avoided.
In one example, the optical sensor is an infrared sensor 111, the infrared sensor 111 includes an infrared emitter and an infrared receiver, and the infrared emitter and the infrared receiver are both disposed on an inner side wall between a water outlet of the water dispenser 2 and the water receiving table, the infrared emitter emits infrared rays in a direction perpendicular to the water outlet of the water dispenser 2, when an object approaches the water receiving table of the water dispenser 2 and blocks the infrared rays, the infrared rays pass through the surface of the object and are reflected, and after the infrared receiver receives the reflected infrared rays, a detection signal is generated, and then the processor 12 determines whether the object is a target water receiving container by combining the water receiving signal and the detection signal.
After the water receiving signal is generated, the processor 12 determines whether the object is the target water receiving container according to whether the detection signal is stable within a preset time period, that is, when the detection signal is unstable within the preset time period, it determines that the object is not the target water receiving container, and further prohibits the water dispenser 2 from discharging water. In one example, the preset time period is greater than 2 seconds.
In the above example, the distance of the infrared ray emitted by the infrared emitter is set to be less than 5cm by the user, that is, when the distance from the object to the infrared emitter is within 5cm, the infrared ray emitted by the infrared emitter can be emitted through the surface of the object and received by the infrared receiver, and a detection signal is generated, and when the distance from the object to the infrared emitter is greater than 5cm, the infrared ray emitted by the infrared emitter cannot irradiate the surface of the object, and the infrared receiver cannot receive the reflected infrared ray, and therefore cannot generate the detection signal.
It is understood that the distance that the infrared emitter emits infrared rays may also be set by a user to other value ranges to detect whether there is an object receiving the detection area of the water table.
In one example, the processor 12 is set by the user to determine whether the detection signal is stable within 2 seconds to determine whether the object is the target water receiving container, that is, when the detection signal still exists stably within 2 seconds after the processor 12 receives the detection signal, it is determined that the object generating the detection signal is the target water receiving container, and otherwise, when the detection signal disappears suddenly within 2 seconds after the processor 12 receives the detection signal, it is determined that the object generating the detection signal is the non-target water receiving container. It can be understood that the target water receiving container can be a water cup, a water kettle and other containers for receiving water. The processor 12 may also be configured by the user to determine whether the object is the target receptacle by detecting whether the signal is stable at other time ranges.
Fig. 4 is a schematic front projection structure diagram of a device for a water dispenser according to an embodiment of the invention. As shown in fig. 4, in an example, taking an infrared sensor as an example, the infrared sensor 111 is installed at a height h between the water outlet of the water dispenser 2 and the water receiving table to form a water receiving table detection area, the height of the shortest water receiving container suitable for the water dispenser in life may be set as a minimum height h1 (i.e. a minimum set height), and the height of the highest water receiving container suitable for the water dispenser may be set as a maximum height h2 (i.e. a maximum set height), and at this time, h should satisfy h1 ≦ h 2. That is, all or most of the water receiving containers suitable for the water dispenser can be detected. In one example, in order to detect the water receiving container more accurately, a plurality of infrared sensors 111 may be provided in a vertical direction. When the water receiving container is placed on the water receiving platform, infrared rays emitted by the infrared emitter can be blocked, and the infrared rays are received by the infrared receiver after being reflected by the water receiving container, so that a detection signal is generated. The processor 12 determines whether the object is the target water receiving container according to whether the detection signal is stable within the preset time period, that is, when the detection signal is unstable within the preset time period, it determines that the object is not the target water receiving container, and further prohibits the water dispenser 2 from discharging water.
It is to be understood that the set height of the infrared sensor having the lowest height among the plurality of infrared sensors 12 may be the same as the minimum set height. For example, assuming that the minimum height of the water receiving container is 10cm and the maximum height is 25cm, the infrared sensor 111 may be disposed at a height of 10cm to 25cm, for example, 12 cm. In the case where a plurality of infrared sensors are provided, the setting heights may be, for example, 10cm, 15cm, 20cm, 25cm, respectively.
Thus, for objects of non-target receiving containers, such as spoons, chopsticks, etc., the height is generally less than the minimum height, when a user places these objects on the water receiving table, the infrared rays emitted by the infrared emitter cannot irradiate the surface of the objects, and the reflected infrared rays cannot be received by the infrared receiver, so that a detection signal cannot be generated, thereby prohibiting the water dispenser 2 from discharging water;
when a user holds objects such as a spoon, chopsticks and the like to pass through a detection area of the water receiving table at the same height as that of the infrared sensor 111, the objects can instantly block infrared rays emitted by the infrared emitter and are received by the infrared receiver at one of the detection areas, so that a detection signal is generated, but after the objects pass through the position of the infrared emitter, the infrared rays emitted by the infrared emitter cannot irradiate the surface of the objects, the infrared receiver cannot receive reflected infrared rays, so that the detection signal is interrupted, and at the moment, the processor 12 judges that the objects are non-target water receiving containers and prohibits the water dispenser 2 from discharging water. In one example, the processor 12 may be set by the user to determine whether the detection signal is stable (continuously present) within 2 seconds to determine whether the object is the target water receiving container, and the duration of the detection signal generated by the object passing through the infrared sensor 111 is 0.5 seconds, that is, the detection signal is not stably present within 2 seconds, so that the object is determined to be the non-target water receiving container.
In other examples, the optical sensor is a time of flight (TOF) sensor, the TOF sensor 112 includes an emitter and a detector, the emitter and the detector are both disposed on an inner side wall between a water outlet of the water dispenser 2 and the water receiving platform, the emitter emits light in a direction perpendicular to the water outlet of the water dispenser, when an object approaches the water receiving platform of the water dispenser 2 and blocks the light, the light is reflected by the surface of the object, and after receiving the reflected infrared light, a detection signal is generated, and the processor 12 determines the detection signal to determine whether the object is a target water receiving container.
It can be understood that, compared with the infrared sensor 111, the TOF sensor 112 has higher detection precision, and the obtained detection signal is linear, that is, the TOF sensor 112 can generate a detection signal with strong and weak information in the process that an object enters the detection area of the water receiving platform, so as to push the distance between the object and the TOF sensor 112 and the motion track of the object, thereby improving the accuracy of the processor 12 in judging whether the object is a target water receiving container, improving the water outlet accuracy of the water dispenser 2, and avoiding water leakage or potential safety hazard of the water dispenser 2.
In one example, the TOF sensor 112 is configured to detect whether an object enters the drip station detection region of the water dispenser 2 between the farthest set distance and the nearest set distance, thereby avoiding unnecessary operations by the processor 12. Specifically, the TOF sensor 112 is configured to detect whether an object enters a water receiving platform area of the water dispenser 2 within a range of 0cm to 20cm, that is, when the object enters the water receiving platform detection area, the object first passes through a farthest range 20cm that the TOF sensor 112 can detect, and continues to approach the water receiving platform detection area from the farthest range, at this time, the TOF sensor 112 generates a linear detection signal, so that the detection signal changes in intensity along with the change in distance between the object and the TOF sensor 12, and remains stable when the object stops moving, and the processor 12 determines whether the detection signal determines that the object is a target water receiving container.
In an example, taking a TOF sensor as an example, the TOF sensor 112 is installed at a height h between the water outlet of the water dispenser 2 and the water receiving platform, the height of the shortest water receiving container applicable in life can be set as a minimum height h1 (i.e. a minimum set height), and the height of the highest water receiving container applicable to the water dispenser can be set as a maximum height h2 (i.e. a maximum set height), and at this time, h should satisfy h1 ≦ h 2. That is, all or most of the water receiving containers suitable for the water dispenser can be detected. In one example, to enable more accurate detection of the water receiving container, a plurality of TOF sensors 112 may be provided in a vertical direction. When the water receiving container is placed on the water receiving platform, light rays emitted by the emitter can be blocked, and the light rays are reflected by the water receiving container and then detected by the detector, so that a detection signal is generated. The processor 12 determines whether the object is the target water receiving container according to whether the detection signal is stable within the preset time period, that is, when the detection signal is unstable within the preset time period, it determines that the object is not the target water receiving container, and further prohibits the water dispenser 2 from discharging water.
It will be appreciated that the set height of the TOF sensor of the plurality of TOF sensors 112 having the lowest height is the same as the minimum set height. For example, assuming a minimum height of 10cm and a maximum height of 25cm for the water-holding container, the TOF sensor 112 may be provided at a height of between 10cm and 25cm, for example 12 cm. In the case where a plurality of TOF sensors are provided, the setting heights may be, for example, 10cm, 15cm, 20cm, 25cm, respectively.
Thus, for objects other than the intended receiving container, such as spoons, chopsticks, etc., the height is generally less than the minimum height, and when the user places these objects on the water receiving station, the light emitted by the emitter cannot strike the surface of the object, and the reflected light cannot be detected by the detector, so that a detection signal cannot be generated, thereby prohibiting the water dispenser 2 from dispensing water. When the user holds objects such as a spoon and chopsticks to pass through the detection area of the water receiving table at the same height as that of the TOF sensor 112, the TOF sensor 112 can detect the motion track of the objects in the detection range and generate linear detection signals at the moment, and the processor 12 judges that the objects are non-target water receiving containers and prohibits the water dispenser 2 from discharging water because the detection signals are not stable detection signals.
In one example, the processor 12 may be configured by the user to determine whether the stable detection signal is stable (persists) within 2 seconds to determine whether the object is the target receptacle, the object passes the TOF sensor 112 and generates a stable detection signal for 0.5 seconds, i.e., the detection signal does not persist for 2 seconds, and thus determine that the object is a non-target receptacle.
In the embodiment of the invention, the water dispenser 2 comprises the device 1 for the water dispenser, the water dispenser 2 can detect whether an object put in by a user is a target water receiving container, the water outlet of the water dispenser is controlled under the condition that the object is determined to be the target water receiving container, so that the water outlet accuracy of the water dispenser is improved, the water outlet of the water dispenser 2 is forbidden under the condition that the object is determined not to be the target water receiving container, and the water leakage or potential safety hazard caused when the user puts a non-target water receiving container into a water receiving table area of the water dispenser 2 through misoperation can be avoided.
In an embodiment of the present invention, the apparatus 1 for a water dispenser comprises an ultrasonic detector 113, at least one detection device 11 and a processor 12; the ultrasonic detector 113 is configured to detect that an object is located in a water receiving table area of the water dispenser 2, generate a water receiving signal in response to detecting that the object is located in the water receiving table area, the at least one detection device 11 is configured to detect that the object enters the water receiving table detection area of the water dispenser 2, generate a detection signal in response to detecting that the object enters the water receiving table detection area, and the processor 12 is configured to receive the water receiving signal and the detection signal and judge whether the placed object is a target water receiving container, and control water outlet of the water dispenser 2 to improve accuracy of water outlet of the water dispenser 2 in the case that the object is determined to be the target water receiving container; and under the condition that the object is determined not to be the target water receiving container, the water outlet of the water dispenser 2 is forbidden, so that the water dispenser 2 is prevented from leaking water or generating potential safety hazards.
In one example, the ultrasonic detector 113 is disposed at the water outlet of the water dispenser 2 and emits ultrasonic waves toward the water outlet of the water dispenser 2 to detect whether an object is located in the water receiving platform area, that is, whether the object is located corresponding to the water outlet, so as to prevent the water from the water dispenser 2 from not falling into the target water receiving container accurately when the object is the target water receiving container and generating a water receiving signal when the object is located in the water receiving platform area. Specifically, when the position of the object corresponds to the water outlet, the ultrasonic detector 113 detects the height change of the water receiving table area according to the reflected sound wave, and at this time, it is determined that the object is located in the water receiving table area and generates a water receiving signal; when the position of the object does not correspond to the water outlet, the ultrasonic detector 113 detects that the height of the water receiving table area is unchanged according to the reflected sound wave, and at the moment, the object is determined not to be in the water receiving table area, and a water receiving signal cannot be generated.
In an embodiment of the present invention, at least one detection device 11 comprises an optical sensor, such as an infrared sensor 111, a TOF sensor 112, or the like.
In one example, the optical sensor is an infrared sensor 111, and the specific structure, the installation position, the detection parameters, and the like of the infrared sensor 111 are the same as those of the above embodiment, which is not described herein again.

Fig. 5 is a flow chart of the steps of a method for a water dispenser according to an embodiment of the present invention. As shown in fig. 5, in the embodiment of the present invention, there is also provided a method for a water dispenser, which is applied to the above device 1 for a water dispenser, and the method for a water dispenser includes the following steps:
step S1: detecting that an object is located in a water receiving table area of the water dispenser;
step S2: generating a water receiving signal in response to detecting that the object is located in the water receiving table area;

step S6: controlling the water dispenser to discharge water under the condition that the object is determined to be the target water receiving container;
step S7: and in the case that the object is determined not to be the target water receiving container, the water outlet of the water dispenser is forbidden.
Firstly, detecting whether an object is positioned in a water receiving platform area through an ultrasonic detector, generating a water receiving signal when the detected object is positioned in the water receiving platform area, and further detecting the object when the object enters the water receiving platform detection area and generating a detection signal; then, determining whether the entering object is a target water receiving container or not according to the water receiving signal and the detection signal; finally, under the condition that the object is determined to be the target water receiving container, the water outlet of the water dispenser 2 is controlled, so that the water outlet accuracy of the water dispenser 2 is improved; and under the condition that the object is determined not to be the target water receiving container, the water outlet of the water dispenser 2 is forbidden, so that the water dispenser 2 is prevented from leaking water or generating potential safety hazards.
In step S1, the ultrasonic detector 113 detects that the object is located in the water receiving platform area, that is, whether the position of the object corresponds to the water outlet, in step S3, the at least one detection device 11 detects that the object enters the water receiving platform detection area of the water dispenser 2, and generates a detection signal when the object is detected to enter the water receiving platform detection area, in steps S5 to S6, the processor 12 determines whether the object is a target water receiving container according to the detection signal, and controls the water dispenser 2 to discharge water when the object is determined to be the target water receiving container, and prohibits the water dispenser 2 from discharging water when the object is determined not to be the target water receiving container.
In one example, the ultrasonic detector 113 is disposed at the water outlet of the water dispenser 2 and emits ultrasonic waves toward the water outlet of the water dispenser 2 to detect whether an object is located in the water receiving platform area, i.e., whether the object is located corresponding to the water outlet, so as to prevent the water from the water dispenser 2 from not falling into the target water receiving container accurately and causing a water leakage event. Specifically, when the position of the object corresponds to the water outlet, the ultrasonic detector 113 detects the height change of the water receiving table area according to the reflected sound wave, and at the moment, the object is determined to be located in the water receiving table area and a water receiving signal is generated; when the position of the object is not corresponding to the water outlet, the ultrasonic detector 113 detects that the height of the water receiving platform area is not changed according to the reflected sound wave, and at the moment, it is determined that the target water receiving container is not in the water receiving platform area, and a water receiving signal cannot be generated.
In one example, the at least one detection device 11 includes an optical sensor, the optical sensor may be an infrared sensor 111, the infrared sensor 111 includes an infrared emitter and an infrared receiver, and the infrared emitter and the infrared receiver are both disposed on an inner side wall between a water outlet of the water dispenser 2 and the water receiving platform, the infrared emitter emits infrared rays in a direction perpendicular to the water outlet of the water dispenser 2, when an object approaches to a detection area of the water receiving platform of the water dispenser 2 and blocks the infrared rays, the infrared rays are reflected by a surface of the object, and after the infrared receiver receives the reflected infrared rays, a detection signal is generated, and the processor 12 determines whether the object is a target water receiving container or not by determining the detection signal.
Fig. 6 is a flowchart of the step of S3 in the method for the water dispenser according to the embodiment of the present invention. As shown in fig. 6, in the embodiment of the present invention, the step of detecting that an object enters the detection area of the water receiving platform of the water dispenser further includes the following steps:
step S31: detecting whether the height of the object is between the minimum set height and the maximum set height, wherein the height of the target water receiving container is between the minimum set height and the maximum set height;
step S32: and determining that the object enters a detection area of a water receiving platform of the water dispenser under the condition that the height of the object is detected to be between the minimum set height and the maximum set height.
Whether the height of an object entering a detection area of a water receiving table of the water dispenser meets requirements is judged by detecting whether the height of the object is between the minimum set height and the maximum set height, and the object is determined to enter the detection area of the water receiving table of the water dispenser under the condition that the height of the object entering the detection area of the water receiving table is detected to be between the minimum set height and the maximum set height.
Fig. 7 is a flowchart of the step of S3 in the method for the water dispenser according to the embodiment of the present invention. As shown in fig. 7, in the embodiment of the present invention, determining whether the object is the target water receiving container according to the detection signal further includes the following steps:
step S51: determining whether the detection signal is stable within a preset time period;
step S52: and under the condition that the detection signal is determined to be unstable in a preset time period, determining that the object is not the target water receiving container.
When determining whether the object is the target water receiving container according to the detection signal, the processor 12 firstly determines whether the detection signal is stable within a preset time period; and under the condition that the detection signal is determined to be unstable in the preset time period, the object is determined not to be the target water receiving container, and then the water outlet of the water dispenser 2 is forbidden, so that the water leakage or potential safety hazard of the water dispenser 2 is avoided.
In one example, the processor 12 is set by the user to determine whether the detection signal is stable within 2 seconds to determine whether the object is the target water receiving container, that is, when the detection signal still exists stably within 2 seconds after the processor 12 receives the detection signal, it is determined that the object generating the detection signal is the target water receiving container, and otherwise, when the detection signal disappears suddenly within 2 seconds after the processor 12 receives the detection signal, it is determined that the object generating the detection signal is the non-target water receiving container.
