As shown in fig. 1 to 2, a method for controlling a water dispenser according to an embodiment of a first aspect of the present invention includes:
s100, acquiring a first water temperature of the hot water tank 100 and/or a second water temperature of the cold water tank 102;
s200, based on the fact that the first water temperature is larger than a first preset water temperature, water is replenished to the hot water tank 100 for a first preset time, wherein the first preset time is smaller than the alarm triggering time;
s300, on the basis that the second water temperature is smaller than a second preset water temperature, water is supplemented to the cold water tank 102 for a second preset time, wherein the second preset time is smaller than the alarm triggering time.
The control method of the water dispenser provided by the embodiment of the invention can ensure that the water system leakage alarm of the railway vehicle is not triggered when the water is supplemented into the hot water tank 100 and/or the cold water tank 102, the condition of the railway vehicle water system leakage false alarm caused by the continuous water supplementation into the hot water tank 100 and/or the cold water tank 102 is eliminated, and the leakage detection requirement of the railway vehicle water system can be completely adapted by respectively obtaining the first water temperature and the second water temperature in the hot water tank 100 and/or the cold water tank 102, respectively supplementing water into the hot water tank 100 and/or the cold water tank 102 for a first preset time and a second preset time based on the first water temperature and the second water temperature, and setting the first preset time and the second preset time to be less than the alarm triggering time, namely supplementing water into the hot water tank 100 and/or the cold water tank 102 in a stepping water supplementing mode, the normal use of the leakage detection system of the rail vehicle water system is ensured.
Specifically, in the method for controlling a water dispenser according to the embodiment of the first aspect of the present invention, the method mainly includes the following steps:
s100, acquiring a first water temperature of the hot water tank 100 and/or a second water temperature of the cold water tank 102;
in this step, a first water temperature in the hot water tank 100 and a second water temperature in the cold water tank 102 may be detected by temperature sensors provided in the hot water tank 100 and the cold water tank 102, respectively.
In addition, before performing step S100, if the water level in the hot water tank 100 is lower than the low water level of the hot water tank 100 and the water level in the cold water tank 102 is lower than the low water level of the cold water tank 102, before step S100, the following steps may be further included:
s10, supplementing water into the hot water tank 100 for a fifth preset time period until the water level in the hot water tank 100 is larger than or equal to the low water level in the hot water tank 100, and starting the heating equipment 106 in the hot water tank 100; and the fifth preset time length is less than the alarm triggering time length.
In other words, before step S100 is executed, if the liquid level probe 104 in the hot water tank 100 detects that the water level in the hot water tank 100 is lower than the low water level of the hot water tank 100, that is, when the hot water tank 100 is fed with water for the first time, a step-by-step water replenishing manner is firstly adopted in the hot water tank 100, so that the water level in the hot water tank 100 is at least greater than or equal to the low water level in the hot water tank 100, thereby preventing the heating device 106 in the hot water tank 100 from being burned out, avoiding the hot water tank 100 from being burned out, and simultaneously, effectively saving energy consumption. Before the water supply, the raw water may be purified by the purified water tank 120 and then supplied to the hot water tank 100.
Wherein, the mode that adopts marching type moisturizing specifically does: the fifth preset time period for water replenishment into the hot water tank 100 is shorter than the alarm triggering time period, so that the water system leakage alarm of the railway vehicle can be prevented from being triggered in the process of water replenishment into the hot water tank 100. For example, if the alarm triggering time period is 3 minutes, the fifth preset time period may be controlled to be 2 minutes. After the fifth preset time period, the operation may be stopped for a certain time, for example, 1 minute, and the water is refilled into the hot water tank 100 for the fifth preset time period, until the water level in the hot water tank 100 reaches the low water level in the hot water tank 100, and the heating device 106, such as a heating pipe, in the hot water tank 100 is synchronously turned on. Moreover, in order to avoid frequent start and stop of the heating device 106 during the water replenishing process, the heating device 106 is always kept in an open state during the water replenishing process. Therefore, the number of start-stop times of the heating equipment 106 can be reduced, and the service life of the heating equipment 106 is ensured.
Similarly, before step S100 is executed, if the liquid level probe 104 in the cold water tank 102 detects that the water level in the cold water tank 102 is lower than the low water level of the cold water tank 102, that is, when the cold water tank 102 is filled with water for the first time, a step-by-step water replenishing manner is firstly adopted in the cold water tank 102, so that the water level in the cold water tank 102 is at least greater than or equal to the low water level in the cold water tank 102, thereby preventing the idle consumption of the refrigeration equipment 108 in the cold water tank 102, and also effectively saving energy consumption. Before water is replenished, raw water may be purified by the fresh water tank 120 and then replenished to the cold water tank 102.
The method comprises the following specific steps:
s20, supplementing water into the cold water tank 102 for a sixth preset time until the water level in the cold water tank 102 is larger than or equal to the low water level in the cold water tank 102, and starting the refrigeration equipment 108 in the cold water tank 102; and the sixth preset time length is less than the alarm triggering time length.
And a sixth preset time is set for supplementing water into the cold water tank 102, and the sixth preset time is shorter than the alarm triggering time, so that the water system leakage alarm of the railway vehicle can be prevented from being triggered in the water supplementing process of the cold water tank 102. For example, if the alarm triggering time period is 3 minutes, the sixth preset time period may be controlled to be 2 minutes. After the sixth preset time period for water supplement into the cold water tank 102, the machine may stop for a certain time, for example, 1 minute, and supplement water into the cold water tank 102 for the sixth preset time period again until the water level in the cold water tank 102 reaches the low water level in the cold water tank 102, and the refrigeration equipment 108, such as a semiconductor refrigeration device, in the cold water tank 102 is synchronously turned on. Moreover, in order to avoid frequent start and stop of the refrigeration equipment 108 in the water replenishing process, the refrigeration equipment 108 is always kept in an open state in the water replenishing process. Therefore, the number of starting and stopping times of the refrigeration equipment 108 can be reduced, and the service life of the refrigeration equipment 108 is ensured.
S200, based on the fact that the first water temperature is larger than a first preset water temperature, water is replenished to the hot water tank 100 for a first preset time, wherein the first preset time is smaller than the alarm triggering time;
in this step, if the detected first water temperature in the hot water tank 100 is greater than the first preset water temperature, water is supplied to the hot water tank 100 in a step-by-step water supply manner for a first preset time.
The first preset water temperature may be 90 degrees celsius, for example, that is, when the detected first water temperature is greater than 90 degrees celsius, it is proved that the water temperature in the hot water tank 100 exceeds the drinkable hot water temperature standard, and at this time, the water inlet solenoid valve 110 is opened, the booster pump 112 is started, and water starts to be supplied to the hot water tank 100. Further, for example, if the alarm triggering time period is 3 minutes, the first preset time period may be controlled to be 2 minutes.
After step S200, the following steps may be further included:
s210, stopping for a third preset time, wherein the sum of the third preset time and the first preset time is less than or equal to the alarm triggering time;
namely, after the first preset time period is supplemented to the hot water tank 100, the machine is stopped for the third preset time period, and then the first preset time period is supplemented to the hot water tank 100, and the step-by-step water supplement to the hot water tank 100 is realized through the cyclic reciprocating. The sum of the third preset time and the first preset time is less than or equal to the alarm triggering time, so that the water system leakage alarm of the railway vehicle can be prevented from being triggered in the process of supplementing water to the hot water tank 100, and the normal use of the water system leakage detection system of the railway vehicle is ensured. As mentioned above, for example, if the alarm triggering time period is 3 minutes, the third preset time period may be controlled to be 1 minute.
After step S210, the following steps are also included:
and S220, stopping water supplement based on the water level of the hot water tank 100 being more than or equal to the high water level of the hot water tank 100 or the first water temperature being less than or equal to the first preset water temperature.
In other words, when water is supplied into the hot water tank 100 to make the water level inside the hot water tank 100 higher than or equal to the high water level of the hot water tank 100, the water supply is stopped; or, when the first water temperature in the hot water tank 100 is detected to be less than or equal to the first preset water temperature again, the water supply is stopped.
That is, when the level probe 104 in the hot water tank 100 detects that the water level in the hot water tank 100 is greater than or equal to the high water level of the hot water tank 100, it is proved that the water amount in the hot water tank 100 is full, and at this time, the water supplement needs to be stopped in order to avoid overflowing the water in the hot water tank 100.
Alternatively, when the temperature sensor in the hot water tank 100 detects that the first water temperature in the hot water tank 100 is less than or equal to the first preset water temperature, it is proved that the water temperature in the hot water tank 100 has not reached the drinkable hot water temperature standard, and at this time, the water supplement needs to be stopped to heat the water in the hot water tank 100.
S300, on the basis that the second water temperature is smaller than a second preset water temperature, water is supplemented to the cold water tank 102 for a second preset time, wherein the second preset time is smaller than the alarm triggering time;
in this step, if the detected second water temperature in the cold water tank 102 is less than the second preset water temperature, water is supplemented into the cold water tank 102 in a step water supplementing manner for a second preset time.
The second preset water temperature may be 18 degrees celsius, for example, that is, when the detected second water temperature is less than 18 degrees celsius, it is proved that the water temperature in the cold water tank 102 is lower than the drinkable cold water temperature standard, at this time, the water inlet solenoid valve 110 is opened, the booster pump 112 is started, and water starts to be supplied to the cold water tank 102. In addition, for example, if the alarm triggering time period is 3 minutes, the second preset time period may be controlled to be 2 minutes.
After step S300, the following steps may be further included:
and S310, stopping the machine for a fourth preset time, wherein the sum of the fourth preset time and the second preset time is less than or equal to the alarm triggering time.
Namely, the water is replenished into the cold water tank 102 through the second preset time length, the machine is stopped for the fourth preset time length, then the water is replenished into the cold water tank 102 through the second preset time length, and the water is circulated, so that the stepping water replenishing into the cold water tank 102 is realized. The sum of the fourth preset time and the second preset time is less than or equal to the alarm triggering time, so that the water system leakage alarm of the railway vehicle can be prevented from being triggered in the water replenishing process of the cold water tank 102, and the normal use of the water system leakage detection system of the railway vehicle is ensured. As mentioned above, for example, if the alarm triggering time period is 3 minutes, the fourth preset time period may be controlled to be 1 minute.
After step S310, the following steps are also included:
and S320, stopping water replenishing based on the water level of the cold water tank 102 being greater than or equal to the high water level of the cold water tank 102 or the second water temperature being greater than or equal to the second preset water temperature.
In other words, when water is replenished into the cold water tank 102 to make the water level inside the cold water tank 102 higher than or equal to the high water level of the cold water tank 102, the water replenishment is stopped; or, when the second water temperature in the cold water tank 102 is detected to be greater than or equal to the second preset water temperature again, the water replenishing is stopped.
That is, when the level probe 104 in the cold water tank 102 detects that the water level in the cold water tank 102 is higher than or equal to the high water level of the cold water tank 102, it is proved that the water amount in the cold water tank 102 is full, and at this time, the water supplement needs to be stopped in order to avoid the overflow of the water in the cold water tank 102.
Alternatively, when the temperature sensor in the cold water tank 102 detects that the second water temperature in the cold water tank 102 is greater than or equal to the second preset water temperature, it is verified that the water temperature in the cold water tank 102 exceeds the drinkable cold water temperature standard, and at this time, the water supplement needs to be stopped to refrigerate the water in the cold water tank 102.
In addition, the control method of the water dispenser further comprises the following steps:
s400, based on the fact that the water level of the hot water tank 100 is smaller than or equal to the middle water level of the hot water tank 100, water is replenished to the hot water tank 100 for a first preset time;
and on the basis that the water level of the cold water tank 102 is less than or equal to the middle water level of the cold water tank 102, replenishing water to the cold water tank 102 for a second preset time.
In other words, with the demand of the passenger, when the liquid level probe 104 in the hot water tank 100 detects that the water level in the hot water tank 100 is less than or equal to the middle water level of the hot water tank 100, the water can be repeatedly supplemented into the hot water tank 100 for a first preset time period, and the above steps S200 to S220 are repeated;
similarly, when the liquid level probe 104 in the cold water tank 102 detects that the water level in the cold water tank 102 is less than or equal to the middle water level of the cold water tank 102, the water can be repeatedly supplemented into the cold water tank 102 for a second preset time period, and the steps S300 to S320 are repeated.
In addition, the control method of the water dispenser further comprises the following steps:
and S500, controlling a blowing device to blow air into the fresh water tank 120 to empty the fresh water tank 120 and the hot water tank 100 and/or the cold water tank 102 based on the emptying signal of the hot water tank 100 and/or the cold water tank 102.
As shown in fig. 2, when an evacuation signal of centralized control of the vehicle is received or a one-key evacuation button on the water dispenser is operated, the drain solenoid valves 114 in the hot water tank 100 and the cold water tank 102 are powered on and opened; the water inlet electromagnetic valves 110 in the hot water tank 100 and the cold water tank 102 are closed by power; the two-position three-way electromagnetic valve 116 is powered to open the normally closed branch and close the normally open branch, the air pump 118 connected with the air compressor is started to press the water purification tank 120, and after the air pressure in the water purification tank 120 is increased, compressed air flows to the hot water tank 100 and/or the cold water tank 102 respectively, so that water in the hot water tank 100 and/or the cold water tank 102 is discharged out of the vehicle through the drain pipes connected to the bottoms of the hot water tank 100 and the cold water tank 102 respectively, and meanwhile, the emptying is also realized in the water purification tank 120. Until the evacuation signal is turned off, the system is reset and in a standby state.
