[0052] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0053] Example 1

[0054] Embodiment 1 of the present invention provides an energy-saving control method, which is applied to a water dispenser. The water dispenser may include but is not limited to the following modules: a main control MCU (Microcontroller Unit), a display panel, a networking module, a heating module, a distance measurement module, a water pump, and an inlet and outlet water valve, so as to respectively realize the conventional functions of the water dispenser, such as controlling the heating module to realize heating, controlling the water pump or the inlet and outlet water valve to realize water production, and controlling the display panel to realize status display.

[0055] Figure 1 This is a flow chart of an energy-saving control method provided in Example 1 of the present invention. The executor of the energy-saving control method provided in this embodiment can be the main control MCU or any main control unit of any water dispenser, which is not specifically limited here.

[0056] Energy-saving control methods include:

[0057] S11. When the first time period when no one has been fetching water from the water dispenser is longer than the first time period threshold, the water dispenser is controlled to enter an energy-saving state.

[0058] The first duration starts recording when the water dispenser is powered on and starts working and no one is taking water. Energy-saving states include but are not limited to turning off the display panel, stopping heating, stopping water production, etc., so that the water dispenser can achieve energy saving when no one is using it. For example, a water dispenser installed in a company can be controlled to enter an energy-saving state after the company gets off work to achieve energy saving.

[0059] In one embodiment, step S11 includes:

[0060] When no one is getting water from the water dispenser, the first duration when no one is getting water is counted; when the first duration is greater than the first duration threshold and less than the second duration threshold, the water dispenser is controlled to enter the first energy-saving state; when the first duration is greater than the second duration threshold and less than the third duration threshold, the water dispenser is controlled to enter the second energy-saving state.

[0061] The energy consumption of the second energy-saving state is less than that of the first energy-saving state.

[0062] The first duration threshold and the second duration threshold in this embodiment can be selected according to the actual application scenario, and are not specifically limited here. Taking a water dispenser installed in a company as an example, the first duration threshold can be 1 hour, and the second duration threshold can be 3 hours.

[0063] In a specific implementation, controlling the water dispenser to enter the first energy-saving state includes: controlling the water dispenser to stop heating.

[0064] Among them, the first energy-saving state is generally applied to the situation where no one drinks water for a short period of time. Taking the water dispenser installed in the company as an example, when no one takes water for a short period of time during the day on weekdays, the heating module of the water dispenser is controlled to stop heating to save energy; at the same time, other modules of the water dispenser, including but not limited to the ranging module, networking module, water pump or inlet and outlet valves, are all in operation, so that the water dispenser can be woken up in time to provide water to users when water is needed.

[0065] In a specific implementation, controlling the water dispenser to enter the second energy-saving state includes: controlling all modules of the water dispenser except the distance measuring module to stop running.

[0066] Among them, the second energy-saving state is generally used in the case where no one fetches water for a long time. For example, the water dispenser installed in the company is controlled to enter the second energy-saving state on weekday evenings or holidays: all modules except the distance measurement module are stopped. Because in this scenario, users rarely need water, at this time, only one distance measurement module can be retained to wake up the water dispenser, which can further save energy while being able to wake up the water dispenser in time according to user needs.

[0067] Below Figure 2 Taking this as an example, the step S11 of this embodiment in which the water dispenser is controlled to enter the first energy-saving state and the second energy-saving state is further described:

[0068] Determine whether someone is taking water from the water dispenser. When no one is taking water from the water dispenser, count the first duration of no one taking water. When someone is taking water from the water dispenser, reset the first duration, and count the first duration the next time no one is taking water.

[0069] It is determined whether the first duration exceeds 1 hour, that is, the first duration threshold in this embodiment. If it is determined to be yes, the water dispenser is controlled to enter the first energy-saving state, that is, the water dispenser is controlled to stop heating. If it is determined to be no, the first duration is continued to be timed when no one is taking water.

[0070] It is determined whether the first duration exceeds 3 hours, that is, the second duration threshold in this embodiment. If it is determined to be yes, the water dispenser is controlled to enter the second energy-saving state, that is, all modules of the water dispenser except the ranging module are controlled to stop running.

[0071] In this embodiment, the energy-saving state is controlled in a step-by-step manner according to the first duration of no one fetching water. While saving energy, it can also leave sufficient space to meet the user's water fetching needs, meet the water fetching needs that may arise from users in different situations, and enhance the intelligence and practicality of the water dispenser.

[0072] S12: Control the distance measurement module to measure the target position, and determine a first distance between the person at the target position and the water dispenser.

[0073] The distance measurement module includes but is not limited to infrared distance measurement, radar distance measurement, and ultrasonic distance measurement. The target position generally refers to the position of the person approaching the water dispenser during use, which can be set by the user or automatically determined by the distance measurement module according to the position of the person approaching.

[0074] S13: When the difference between the first distance and the target distance is greater than or equal to the distance threshold, control the water dispenser to exit the energy-saving state.

[0075] In one embodiment, step S13 includes:

[0076] When the difference between the first distance and the target distance is greater than or equal to the first distance threshold and less than the second distance threshold, the water dispenser is controlled to exit the second energy-saving state; when the difference between the first distance and the target distance is greater than or equal to the second distance threshold, the water dispenser is controlled to exit the first energy-saving state; wherein the second distance threshold is greater than the first distance threshold.

[0077] The target distance can be the maximum distance recorded by the distance measuring module in the process of measuring the target position, or can be set by the user according to the actual application scenario. The first distance threshold and the second distance threshold can be selected according to the actual application scenario, and are not limited here. For example, taking a water dispenser installed in a company, the first distance threshold can be 1 meter and the second distance threshold can be 2 meters.

[0078] Let's take the water dispenser installed in the office as an example. Figure 3 Schematic diagram for determining the target distance through the distance measurement module and controlling the water dispenser to exit the energy-saving state:

[0079] The distance measuring module is controlled to measure the target direction, obtain the first distance of the incoming person, and the maximum distance recorded in the first distance is determined as the target distance. When the water dispenser is installed near the office door, the target direction can be toward the office door, and the target distance can be the distance from the water dispenser to the office door.

[0080] Determine whether the first distance decreases, that is, whether the difference between the first distance and the target distance increases. If not, continue to control the distance measurement module to measure the target position; if so, determine whether the difference between the first distance and the target distance is greater than or equal to 2 meters; and if the difference between the first distance and the target distance is less than 2 meters, determine whether the difference between the first distance and the target distance is greater than or equal to 1 meter; 2 meters is the second distance threshold in this embodiment, and 1 meter is the first distance threshold in this embodiment.

[0081] When the difference between the first distance and the target distance is greater than or equal to 1 meter and less than 2 meters, if the water dispenser is in the second energy-saving state, the water dispenser is controlled to exit the second energy-saving state. When the water dispenser is installed near the office door, the difference between the first distance and the target distance is greater than 1 meter, which may be the case when the user comes to work. If the water dispenser is in the second energy-saving state at this time, that is, the water dispenser turns off all other modules except the ranging module, it will not be able to make water in time, resulting in the user being unable to supply water in time when he wants to use water. At this time, it is necessary to control the water dispenser to exit the second energy-saving mode and make water in time when the user comes to work.

[0082] When the difference between the first distance and the target distance is greater than or equal to 2 meters, if the water dispenser is in the first energy-saving state, the water dispenser is controlled to exit the first energy-saving state. If the difference between the first distance and the target distance is greater than 1 meter, it may be that the user comes to get water. At this time, in order to meet all the water needs of the user as much as possible, the water dispenser is promptly controlled to exit the first energy-saving state for heating.

[0083] In this embodiment, through the switching control between the first energy-saving state and the second energy-saving state, the user's intention can be quickly determined, and the best water use experience can be provided to the user while achieving efficient energy saving.

[0084] Example 2

[0085] Embodiment 2 of the present invention provides a flow chart of an energy-saving control method. This embodiment can be implemented on the basis of the energy-saving control method provided in Embodiment 1. For other steps, see Embodiment 1. The energy-saving control method also includes:

[0086] The ranging module is controlled to determine the target position from multiple positions.

[0087] The distance measuring module can be located on the top of the water dispenser, and its connection with the main control MCU of the water dispenser includes but is not limited to wired connection or wireless connection. The main control MCU can control the distance measuring module.

[0088] In the actual installation scenario of the water dispenser, for example, when the water dispenser is installed in a relatively open space, the direction from which the user comes to get water may not only include the front of the water dispenser. If only the front is used as the ranging direction of the ranging module, it is very likely that the water dispenser will not be able to determine the user's arrival in time; and if a surround ranging module is installed, or the ranging module is continuously rotated for all-round judgment, it will cause unnecessary waste of resources and violate the original intention of energy saving, and the accuracy of the judgment of the arrival is not greatly improved. Therefore, the energy-saving control method provided in this embodiment can judge the installation environment of the water dispenser to determine the target direction of the user's main arrival, and can respond in time when the person comes to get water, further improving the user experience and the intelligence and practicality of the water dispenser.

[0089] In one embodiment, Figure 4 A schematic diagram for controlling the ranging module to determine the target position from multiple positions, including:

[0090] S21, controlling the distance measurement module to rotate toward multiple directions, and collecting second distances at multiple directions.

[0091] The second distance is the distance between the obstacle and the water dispenser in each direction. The distance measurement module is explained by taking ultrasonic distance measurement as an example. The distance measurement module transmits ultrasonic waves to a certain direction and starts timing at the same time as the transmission time. The ultrasonic waves propagate in the air and return immediately when they encounter obstacles on the way. The ultrasonic receiver stops timing immediately when it receives the reflected waves. Since the propagation speed of ultrasonic waves in the air is known, the time it takes for the sound waves to be reflected back after encountering obstacles after transmission is measured, and the second distance from the transmission point to the obstacle is calculated based on the time difference between transmission and reception.

[0092] Multiple directions surround the water dispenser, and the angles between two adjacent directions are the same, and the number of directions can be one or more. For example, when there are 4 directions, the size of each direction is 90 degrees, namely the direction directly in front of the water dispenser, the direction directly to the left of the water dispenser, the direction directly to the right of the water dispenser, and the direction directly behind the water dispenser.

[0093] In one embodiment, the rotation of the ranging module is controlled by a motor. After measuring the second distance of each orientation, the motor is controlled to rotate the ranging module to the next orientation to measure the second distance of the next orientation until the second distance measurement of all orientations is completed.

[0094] S22. Determine the target direction from multiple directions according to the second distance.

[0095] In one possible implementation, step S22 specifically includes:

[0096] Selecting, from the plurality of directions, a direction whose second distance is greater than a second distance threshold as the first direction;

[0097] When the number of first positions is less than two, it is considered that the first position corresponding to the largest second distance has a greater possibility of a person coming, and the first position corresponding to the longest second distance is determined as the target position; when the number of first positions is greater than or equal to two, it is considered that multiple positions of the water dispenser have a greater possibility of a person coming, and the middle position of the multiple first positions is determined as the target position.

[0098] Below Figure 5 Taking the example, the control of the ranging module to determine the target position from multiple positions in this embodiment is further described:

[0099] The front direction of the water dispenser is used as the starting point of the motor rotation, the motor of the distance measurement module is controlled to rotate to the 0 degree direction, and the second distance D in the 0 degree direction is recorded. 前 , that is, the direction directly in front of the water dispenser; control the motor of the distance measurement module to rotate 90 degrees, and record the second distance D in the 90-degree direction 左 , that is, the left side of the water dispenser; control the motor of the distance measurement module to rotate to 180 degrees, and record the second distance D in the 180-degree direction 后 , that is, the direction directly behind the water dispenser; control the motor of the distance measurement module to rotate to the 270-degree direction, and record the second distance D in the 270-degree direction 右 , which is the left side of the water dispenser.

[0100] It should be noted that this embodiment only provides an example of controlling the rotation of the ranging module, and the rotation order of the ranging module can be adjusted arbitrarily and is not limited here.

[0101] D 前 , D 左 , D 右 , D 后 The distance greater than 2 meters is determined as the first orientation, and it is determined whether the number of first orientations is greater than or equal to 2, and 2 meters is the second distance threshold in this embodiment.

[0102] When the number is greater than or equal to 2, it is considered that the water dispenser is installed in a relatively open space, such as placed in a hall with its back against a wall. There is a high possibility of people coming in multiple directions of the water dispenser, including but not limited to multiple directions except those facing the wall, and the middle direction of multiple first directions is determined as the target direction; when the number is less than 2, it is considered that the water dispenser is installed in a relatively cramped corner inside the room, such as the end of a corridor, and there is a high possibility of people coming in the first direction corresponding to the second distance of the water dispenser when it is the largest, that is, the direction facing the corridor. At this time, the first direction corresponding to the longest second distance is determined as the target direction.

[0103] In this embodiment, the installation scenario of the water dispenser can be analyzed based on the detection situation of the ranging module, the target position of the person coming can be determined, a more accurate analysis can be performed, and misjudgment can be reduced.

[0104] In one embodiment, see Figure 6 , the energy-saving control method further includes:

[0105] Time the running time of the water dispenser when it is powered on;

[0106] When the first duration is greater than the third duration threshold and the running duration is greater than the running duration threshold, the running duration is cleared and the ranging module is controlled to re-determine the target position from multiple positions.

[0107] Among them, the process of obtaining the first duration can refer to step S11 in Example 1, which will not be repeated here. The third duration threshold and the operating duration threshold can be set according to the actual application scenario and are not limited here. In this embodiment, the third duration threshold is preferably 6 hours, and the operating duration threshold is preferably 3 days.

[0108] In one possible implementation, when the first duration is greater than the third duration threshold and the running duration is greater than the running duration threshold, the unavailable flag of the ranging module is set to 1. Before the water dispenser controls the energy-saving state switching, if it detects that the unavailable flag of the ranging module is 1, the energy-saving state switching is stopped until the ranging module re-determines the target position. This reduces the occurrence of erroneous operations and improves the intelligence and practicality of the water dispenser.

[0109] In this embodiment, when the first time period when no one has been fetching water is greater than the third time period threshold and the running time is greater, the following situation may occur: the water dispenser ranging module makes an error in measuring the target position, and the ranging module cannot determine the accurate measurement position, thereby affecting the user experience, and even worse, causing a large amount of resource waste for the water dispenser. Therefore, when the first time period reaches the third time period threshold and the running time is greater than the running time threshold, the target position can be calibrated in time.
