Description

Technical Field

[0001] This invention relates to the field of water purifier technology, specifically to a control method and system for a water purifier, electronic equipment, and a medium. Background Technology

[0002] Currently, commercial water purifiers on the market can only be set to turn on and off at fixed times. However, in some public places or offices, people arrive early and leave late, so the timing is not consistent. This means that the machine may be turned off when people are present, or it may continue to run even when no one is there, heating a large tank of hot water, which is very wasteful of electricity. Moreover, the demand for hot water varies with the seasons for the same water purifier. Hot water consumption is high in winter and low in summer. Current machines on the market cannot intelligently adjust the hot water output, resulting in significant waste of hot water, electricity, and water.

[0003] Most water dispensers on the market don't discharge water that has been left overnight. Water left overnight is bad for health, and the repeated boiling of the water creates "repeatedly boiled water," which is also harmful. If the machine is turned off and someone wants to get water, it can't automatically turn on, leaving people unable to get water. Without internet access, the machine can't be turned on and off, or in some areas, various reasons may prevent the machine from connecting to the internet. The cost of a network module is high, increasing the burden on both businesses and consumers. The installation and maintenance of the network module, as well as IoT cards, all require significant costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art in that it is impossible to intelligently control the working mode of a water purifier, and to provide a control method and system, electronic equipment and medium for a water purifier.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] Firstly, a control method for a water purifier is provided, the control method comprising:

[0007] The current season is determined based on the heat dissipation of the water in the water tank of the water purifier within a preset time period.

[0008] The operating strategy of the water purifier is determined based on the current season and the resistance data of the photoresistor; wherein, the resistance value of the photoresistor represents the brightness of the environment in which the water purifier is located; the resistance data includes the resistance value and / or the change in the resistance value.

[0009] The water purifier is controlled to operate according to the described working strategy.

[0010] Optionally, determining the current season based on the heat dissipation of the water in the water tank of the water purifier within a preset time period includes:

[0011] If the temperature of the water in the water tank of the water purifier is greater than the first temperature threshold, then the current season is summer.

[0012] Based on the current season and the resistance data of the photoresistor, the operating strategy of the water purifier is determined, including:

[0013] When the current season is summer and the resistance change does not exceed the resistance threshold, the water purifier's working strategy is to add cold water to the water tank and boil it after a preset standby time.

[0014] Optionally, determining the water purifier's operating strategy based on the current season and the photoresistor's resistance data includes:

[0015] After adding cold water to the water tank and boiling it, the timer begins.

[0016] When the resistance of the photoresistor is greater than the first threshold and the duration of the timing is greater than the first duration, the water level of the hot water in the water tank is maintained at no lower than the middle water level, and the current resistance of the photoresistor is determined.

[0017] If the resistance value is greater than the second threshold, and the current season is summer, and the hot water level in the water tank is lower than the low water level, the working strategy of the water purifier is to add cold water to the water tank to the low water level and boil it; wherein, the first threshold is less than the second threshold.

[0018] Optionally, determining the water purifier's operating strategy based on the current season and the photoresistor's resistance data includes:

[0019] If the resistance of the photoresistor is greater than the third threshold and the duration is greater than the second duration, the working strategy of the water purifier is to control the water purifier to enter the shutdown state.

[0020] Optionally, determining the water purifier's operating strategy based on the current season and the photoresistor's resistance data further includes:

[0021] If the water purifier is in the off state and the resistance of the photoresistor is less than the fourth threshold, the water purifier is controlled to enter the on state.

[0022] When the water purifier is turned on, if the water in the water tank of the water purifier decreases to below the low water level, the working strategy of the water purifier is to control the water purifier to replenish cold water to the low water level and boil it; wherein, the third threshold is greater than the fourth threshold.

[0023] Optionally, determining the water purifier's operating strategy based on the current season and the photoresistor's resistance data further includes:

[0024] If the water purifier is in the off state and the resistance of the photoresistor is greater than the third threshold, determine whether the water level in the water tank is high.

[0025] If the water level in the water tank is high, then the cold water in the pressure tank of the water purifier is discharged, and the temperature of the water in the water tank is determined.

[0026] If the temperature of the water in the tank is greater than the second temperature threshold, the water purifier's operating strategy is to open the hot water drain valve until all the hot water is drained.

[0027] Optionally, determining the water purifier's operating strategy based on the current season and the photoresistor's resistance data further includes:

[0028] If the temperature of the water in the tank is not greater than the first temperature threshold, then the current season is winter, and the working strategy of the water purifier is to control the water level in the tank to a high level.

[0029] Secondly, a control system for a water purifier is provided, the control system comprising:

[0032] The control module is used to control the operation of the water purifier according to the operating strategy.

[0033] Thirdly, an electronic device is provided, including a memory, a processor, and a computer program stored in the memory and for running on the processor, wherein the processor executes the computer program to implement the control method for a water purifier as described in the first aspect.

[0034] Fourthly, a computer storage medium is provided, on which a computer program is stored, characterized in that, when the computer program is executed by a processor, it implements the control method for a water purifier as described in the first aspect.

[0035] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0036] The significant advantages of this invention are: it determines the user's water demand based on the current season and the resistance value of the photoresistor, flexibly adjusting the machine's hot water output according to different sunrise times and seasons. This eliminates the need for manually setting timers, ensuring hot water is available upon arrival and preventing water and electricity waste.

[0045] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0046] like Figure 1 As shown, an embodiment of the present invention provides a water purifier control method comprising the following steps:

[0047] S11. Determine the current season based on the heat dissipation of the water in the water tank of the water purifier within a preset time period.

[0048] The water purifier mentioned in this invention refers to one installed in an office or public place, equipped with a hot water tank and a pressure tank, capable of dispensing both hot and cold water. In addition, the water purifier also includes basic components such as a controller, a water dispensing button, a water inlet valve, a heating element, and a hot water outlet valve.

[0049] In one embodiment, the current season is determined based on the heat dissipation of the water in the water tank of the water purifier within a preset time period, including: if the temperature of the water in the water tank of the water purifier is greater than a first temperature threshold, then the current season is summer.

[0050] Based on the current season and the resistance data of the photoresistor, determine the water purifier's operating strategy, including:

[0051] When the current season is summer and the resistance change does not exceed the resistance threshold, the water purifier's working strategy is to add cold water to the water tank and boil it after a preset standby time.

[0052] The first temperature threshold can be set according to the actual situation, such as 10℃ or 20℃.

[0053] The preset duration can be set according to the actual situation, such as half an hour or one hour.

[0054] The resistance threshold can be set according to the actual situation, for example, 1kΩ.

[0055] The water purifier is turned on in the morning to refill and heat water. It judges the heat dissipation based on the water temperature in the hot water tank; heat dissipation is faster in winter and slower in summer. If the water temperature is above a first temperature threshold, it indicates slow heat dissipation, and the current season is summer. If the resistance change does not exceed the resistance threshold, it indicates minimal change, excluding the possibility of a sudden large resistance change due to someone entering the tank. In this case, no additional water needs to be added. After the preset standby time, add cold water to the tank and boil it to maintain the required water usage.

[0056] S12. Determine the working strategy of the water purifier based on the current season and the resistance data of the photoresistor.

[0057] The photoresistor is installed on the water purifier or at a preset distance from the water purifier, facing the light. The resistance value of the photoresistor represents the brightness of the environment in which the water purifier is located.

[0058] Resistance data includes the resistance value and / or the change in resistance value. The change in resistance value is the change in resistance over a period of time. For example, the resistance value remains at 1MΩ for a long time, and then suddenly changes by more than 1kΩ within 5 seconds.

[0059] In one embodiment, the working strategy of the water purifier is determined based on the current season and the resistance data of the photoresistor, including: adding cold water to the water tank and boiling it, then starting the timer; when the resistance of the photoresistor is greater than a first threshold and the duration of the timer is greater than a first duration, then maintaining the water level of the hot water in the water tank at no lower than the middle water level, and determining the current resistance of the photoresistor.

[0060] If the resistance is greater than the second threshold and the current season is summer, the hot water level in the tank is lower than the low water level. The water purifier's working strategy is to add cold water to the tank to the low water level and boil it.

[0061] The first threshold is less than the second threshold. The first and second thresholds can be set according to the actual situation, such as 500kΩ and 700kΩ.

[0062] The first duration can be set according to the actual situation, for example, 10 hours.

[0063] After adding cold water to the water tank and boiling it, the morning water replenishment and heating process is complete, and the daytime workflow begins. The timer starts tracking the elapsed daytime. When the resistance of the photoresistor exceeds the first threshold and the duration is greater than the first time interval, it indicates that the light is dim and the daytime is relatively long. For example, if the daytime duration is 10 hours, it means it's almost dark and it's not winter, so the water demand will gradually decrease. Simply maintain the hot water level at least at the medium level. If the resistance exceeds the second threshold, it means it's already very dark, with only artificial lighting. Since it's summer, the hot water demand is even lower, so simply maintain the hot water level in the tank at a low level.

[0064] In one embodiment, the operating strategy of the water purifier is determined based on the current season and the resistance data of the photoresistor, including:

[0065] If the resistance of the photoresistor is greater than the third threshold and the duration is greater than the second duration, the water purifier's operating strategy is to control the water purifier to enter the shutdown state.

[0066] The third threshold can be set according to the actual situation, for example, 1MΩ. The second duration can be set according to the actual situation, for example, half an hour.

[0067] If the resistance of the photoresistor is greater than the third threshold and the duration is greater than the second duration, for example, if the resistance is greater than 1MΩ and the duration is greater than half an hour, it means that the lights are off and no one is around. The water purifier stops heating, replenishing water and producing water, enters standby energy-saving mode, turns off the display screen and all loads, and enters the shutdown state.

[0068] In one embodiment, determining the water purifier's operating strategy based on the current season and the resistance data of the photoresistor further includes:

[0069] If the water purifier is in the off state and the resistance of the photoresistor is less than the fourth threshold, the water purifier will be turned on.

[0070] When the water purifier is turned on, if the water in the water tank decreases below the low water level, the water purifier's working strategy is to control the water purifier to add cold water to the low water level and boil it.

[0071] The third threshold is greater than the fourth threshold. The third and fourth thresholds can be set according to the actual situation, such as 900kΩ and 1MΩ.

[0072] When the water purifier is off, if the resistance of the photoresistor suddenly becomes less than the fourth threshold, it means that someone has turned on the light and controlled the water purifier to turn on. The screen lights up and the water in the tank is heated to boil. If someone takes hot water and the water level is lower than the low water level, the water is replenished to the low water level and boiled. The water purifier maintains the low water level operation.

[0073] In one embodiment, determining the water purifier's operating strategy based on the current season and the resistance data of the photoresistor further includes:

[0074] If the water purifier is turned off and the resistance of the photoresistor is greater than the third threshold, determine whether the water level in the tank is high.

[0075] If the water level in the tank is high, drain the cold water from the pressure tank of the water purifier and determine the temperature of the water in the tank.

[0076] If the temperature of the water in the tank is higher than the second temperature threshold, the water purifier will open the hot water drain valve until all the hot water is drained.

[0077] The second temperature threshold can be set according to the actual situation, such as 60℃ or 80℃.

[0078] If the resistance of the photoresistor is greater than the third threshold and the water level in the tank is high, it means there is too much hot water. Open the pressure tank drain valve to drain the cold water from the pressure tank and replenish it to the hot water tank. Then check if the temperature in the hot water tank is higher than 80℃. If it is higher than 80℃, it means there is too much hot water and the temperature is too high, which may cause scalding. At this time, open the hot water drain valve to drain the water for 10 seconds, then wait for 20 seconds before draining again, until all the hot water is drained.

[0079] In one embodiment, determining the water purifier's operating strategy based on the current season and the resistance data of the photoresistor further includes:

[0080] If the temperature of the water in the tank is not greater than the first temperature threshold, and the current season is winter, the water purifier's working strategy is to control the water level in the tank to a high level.

[0081] Hot water usage is high at night in winter, so the water purifier maintains full hot water level without lowering the water level.

[0082] S13. Control the operation of the water purifier according to the working strategy.

[0083] The modes for controlling the operation of the water purifier include heating, water replenishment, water boiling, water production, and water drainage.

[0084] The water purifier control method provided in this invention eliminates the need for manual setting of timed on / off times. It intelligently switches on and off, and flexibly adjusts the hot water output based on daylight hours and season, ensuring hot water is always available when someone visits, preventing water and electricity waste. It can also intelligently reduce the hot water output based on ambient light levels at night and the season, avoiding waste. The machine automatically shuts off when no one is present and the lights are turned off, saving energy. It automatically turns on again when someone visits to ensure water supply. It drains overnight water daily, easily addressing the issue of excessive bacteria in the first cup of water, and intelligently drains water based on temperature, preventing damage to drain pipes.

[0085] Furthermore, the water purifier does not require a network module to achieve intelligent on / off operation and can also determine the season. In addition, the cost of the photoresistor used is low, far lower than that of the network module, which can reduce production costs and subsequent maintenance costs.
