For the purpose of facilitating an understanding of the steps of the embodiments of the present invention, a brief background of the invention is now presented.
Tap water enters the bottom of the inner container of the heat storage type water heater, and the original hot water in the water tank is discharged from the top by the pressure of the tap water. In this process, since the tap water entering the water heater from the bottom is mixed with a part of the hot water to lower the temperature of the hot water, the temperature of the hot water used in the thermal storage water heater may be lowered as the temperature is lowered. Assuming that the user wants to take a bath with 40 degrees of hot water, the hot water in the water tank is now 50 degrees. When the user uses the water heater, hot water and cold water are discharged and mixed into hot water of 40 degrees. Meanwhile, because the hot water in the water tank is discharged, the cold water at the water inlet enters the water tank and is mixed with the hot water, and the hot water in the water tank is slowly cooled. When the hot water is 40 degrees, the user cannot wash the water of 40 degrees any more (because the water in the water tank has a lower washing temperature). Therefore, the prior art judges the hot water quantity of the electric water heater through the water temperature of the inner container.
Referring to fig. 2, in a first embodiment of the water heater water quantity control method of the present invention, the water heater water quantity control method includes:
step S10, acquiring the current locked water temperature of the water heater, and acquiring the warning temperature difference value between the current locked water temperature and the current actual water temperature;
the locked water temperature is a preset temperature threshold value of hot water in a water tank of the water heater, and the meaning of the preset temperature threshold value is as follows: when the current actual water temperature of the hot water in the water tank reaches the preset temperature threshold value or is lower than the preset temperature threshold value or the difference value between the current actual water temperature and the preset temperature threshold value is a preset value, the water outlet quantity of the water heater is adjusted according to a preset rule. The preset value is obtained by a water heater manufacturer according to experimental data, the preset value is mainly set by considering the cold-hot water alternating speed or the hot water cooling speed of the water heater, if the current actual water temperature-locked water temperature is 1 ℃, the water heater is required to be stopped soon, and the water is stopped for avoiding half bath and half bath of a user, at the moment, a certain prompt can be given, if the water yield is reduced, the user sees that the water yield is reduced, and knows that the water is required to be stopped soon, and then corresponding measures can be taken. The preset rule indicates that the relation between the locked water temperature and the current actual water temperature is different, and the corresponding water yield is also different, if the current actual water temperature is far greater than the locked water temperature, water is discharged in a normal water yield, and when the current actual water temperature is equal to the locked water temperature, water discharge is stopped.
The locked water temperature can be a temperature value set by a user or a default temperature value of the water heater system. The current lock water temperature is as the name implies the current effective lock water temperature. The current actual water temperature refers to the current actual measured temperature of the hot water in the water tank. The warning temperature difference is the difference between the current locked water temperature and the current actual water temperature.
The first embodiment of the present invention solves the technical problems that: the function of locking the residual water volume is realized, namely, the user can decide how many people can be washed by the residual water. At the moment, the residual hot water quantity in the water tank needs to be determined, and the hot water quantity can be judged according to the hot water temperature in the water tank.
The locking water temperature is a preset temperature threshold value of hot water in the water tank, and meanwhile, the locking water temperature corresponds to a preset water quantity, namely when the temperature of the hot water in the water tank is the locking water temperature, the hot water quantity in the water tank is the preset water quantity. Similarly, the current actual water temperature corresponds to the current water amount, that is, the current hot water amount in the water tank is the current water amount.
According to the relation between the locking water temperature and the current actual water temperature and the water quantity, the warning temperature difference value can refer to the difference between the current water quantity and the preset water quantity, the water outlet quantity of the water heater is adjusted according to the warning temperature difference value, the water quantity expected to be reserved by a user is locked according to the set locking water temperature, the use experience of the user is improved, and if the warning temperature difference value is equal to zero, the water outlet of the water heater is stopped.
In one embodiment, the water heater interactive interface has a clickable control/button for directly setting the locked water temperature, and the user can determine the locked water temperature needed to be set by using experience if the user wants to reserve n individuals of bath water.
The user can determine whether to open the locking mode, which may be a clickable control/button with a locking function opening and canceling on an interactive interface of the water heater shell, or a remote controller connected with the water heater, or remotely controlled in an APP manner of a mobile terminal such as a mobile phone, ipad, PDA (Personal Digital Assistant) and the like. After the locking function of the water heater is started, the water heater can give a certain prompt, for example, a state indicator lamp on the water heater indicates in a preset mode. The above approach (clickable controls/buttons, remote control and APP) is also applicable to the setting of the locked water temperature.
Step S11, acquiring a first water yield corresponding to the warning temperature difference according to the first corresponding relation between the temperature difference and the water yield;
and step S12, controlling the water heater to discharge water at the first water output.
The first corresponding relation may be a mapping table structure or may be a function call for calculation. If the first corresponding relationship is a mapping table structure, after the temperature difference is determined, the corresponding water yield can be determined according to the temperature difference, and the water yield indicates the water yield at the water gap, such as the water yields of three grades of large water yield, small water yield and water cut-off. If the first correspondence is expressed as a function, the water output is calculated based on the temperature difference and the function.
In one embodiment, as shown in FIG. 3, the values of TL and TN are compared (TN is the current actual water temperature and TL is the lock water temperature). The warning temperature difference is delta T-TN-TL, M is a numerical value set by a manufacturer according to the requirement of the manufacturer, M is a positive number, and the warning temperature difference comprises the following components:
when the delta T is larger than or equal to M, the unit keeps a large amount of water outlet (the normal default is a large amount of water outlet state), and the values of TL and TN are compared again;
when the delta T is less than M, the unit is switched to a small amount of water, the values of TL and TN are compared again, and optionally, the unit gives a prompt of a locking state to inform a user that the water volume locking function is started;
and when the delta T is equal to 0, stopping the water outlet of the unit.
In another embodiment, the method may be divided into two stages instead of the third stage, specifically: when TN is greater than TL, the unit keeps a large amount of water; when TN is equal to TL, the unit stops water outlet. Or to divide more gears.
And delta T <0 exists, namely the current actual water temperature is less than the locking water temperature, the existing hot water quantity in the water tank is less than the hot water which a user wants to keep, and at the moment, the unit can stop water outlet and heat again.
And controlling the water heater to discharge water with a first water discharge corresponding to the warning temperature difference, and stopping discharging water to reserve the residual water when the warning temperature difference meets a certain condition and the water discharge is zero.
When the unlocking instruction is detected, the locking is unlocked, and the water heater is controlled to discharge water with normal water quantity.
According to the embodiment, the warning temperature difference value of the current locking water temperature and the current actual water temperature of the water heater is obtained, the first water yield corresponding to the warning temperature difference value is determined, the water heater is controlled to output water at the first water yield, the hot water amount in the water tank can be determined through the change of the hot water temperature in the water tank, the hot water amount in the water tank is ensured to meet the reservation requirement of a user, the water heater water amount control function of the water tank is realized, the user can be ensured that hot water cannot be abused to cause insufficient hot water, the accurate control of the water consumption of the water heater by the user is realized, and.
Further, step S12 is followed by:
step S13, detecting the water outlet flow of the water heater and judging whether the water heater is in the water outlet state;
and if the water heater is in a water outlet state, executing the step of obtaining the warning temperature difference value between the current locked water temperature and the current actual water temperature.
In an embodiment, if the water outlet amount of the water heater can be adjusted in real time, the step of obtaining the current locked water temperature of the water heater or the step of obtaining the warning temperature difference between the current locked water temperature and the current actual water temperature should be performed in real time, and when the current locked water temperature changes or the warning temperature difference caused by the change of the current actual water temperature changes, the water outlet amount of the water heater also changes according to the change, so as to ensure that the reserved water amount expected by the user is finally reserved.
When the current locked water temperature changes, the locked water temperature setting module or the processor may send a prompt that the latest current locked water temperature or the locked water temperature is updated, and at other times, the water heater only repeatedly performs the step of obtaining the warning temperature difference between the current locked water temperature and the current actual water temperature.
When the water heater is used for discharging water, the step of obtaining the warning temperature difference value between the current locking water temperature and the current actual water temperature is repeatedly executed, so that the water discharge quantity is adjusted according to the latest warning temperature difference value after the warning temperature difference value is changed, excessive water consumption is prevented, and the expected reserved water quantity of a user is reserved.
Further, based on the above embodiment, as shown in fig. 4, in the second embodiment of the water quantity control method for a water heater of the present invention, the step of obtaining the current locked water temperature of the water heater includes:
and acquiring the current locked water quantity, and acquiring the current locked water temperature corresponding to the current locked water quantity according to the second corresponding relation between the locked water quantity and the locked water temperature.
Namely, step S20 is: and acquiring the current locked water quantity, acquiring the current locked water temperature corresponding to the current locked water quantity according to the second corresponding relation between the locked water quantity and the locked water temperature, and acquiring the warning temperature difference value between the current locked water temperature and the current actual water temperature.
In this embodiment, for convenience of description, the reserved water amount desired by the user is named as the lock water amount, and the current lock water amount is the current lock water amount. The water temperature can refer to the water quantity to a certain extent, the locking water temperature refers to the water temperature of the locking water quantity, and the second corresponding relation of the locking water temperature and the locking water temperature is affected by nonlinearity of a plurality of factors, so that the second corresponding relation can only be tested by a water heater manufacturer and obtained according to actual experimental test data of the water heater, and the factors comprise the water capacity of the water tank, the current water inlet temperature, the actual temperature of hot water in the water tank, the water outlet temperature and the like.
The second corresponding relation can be a table structure, the current locking water temperature of the water heater can be obtained according to different locking water quantities and different locking water temperatures, and then the current locking water temperature of the water heater can be obtained according to the second corresponding relation.
The current water locking amount can be set by a user, for example, the water locking amount is directly set to be 50L, or can be a default setting of a water heater system, and in this case, as long as the usage locking mode is opened by the user, the water heater sets the default preset water amount to be the current water locking amount. Of course, the user setting priority is higher than the system default setting.
The locked water temperature is obtained by locking the water amount, and the relevant steps are schematically shown in figure 5.
In one embodiment, the water heater can divide the lock water amount into different units by human, such as the water consumption of two persons in the first gear, the water consumption of three persons in the second gear, and the water consumption of 5 persons in the third gear. And the user directly selects the gear to further determine the locking water quantity. The mode is intuitive and convenient for users to use.
The water temperature is determined and locked through the water locking amount, so that the water temperature locking device is more intuitive for users and more beneficial to the users.
Specifically, in step S20, the step of obtaining the current lock water temperature corresponding to the current lock water amount according to the second corresponding relationship between the lock water amount and the lock water temperature includes:
step S21, determining a second corresponding relation between the locking water quantity and the locking water temperature based on the current water inlet temperature, the lowest water temperature of the outlet water and the current actual water temperature;
and step S22, acquiring the current locked water temperature corresponding to the current locked water quantity according to the second corresponding relation.
The current water inlet temperature is the water temperature at the water inlet of the inner container of the water heater, the lowest water outlet temperature is the lowest water temperature specified by a manufacturer and used for people to bath, or the lowest water temperature required by the outlet of the water heater, and the current actual water temperature is the actual temperature of hot water in the water tank.
When other conditions are unchanged, if the current inlet water temperature is lower, the temperature of the hot water in the water tank is reduced faster to reach the same locking water quantity (reserved water quantity), and the locking water temperature needs to be higher. When other conditions are not changed, if the lowest water temperature of the outlet water is increased, the same locking water amount is achieved, and the locking water temperature needs to be higher. And when other conditions are not changed, if the current actual water temperature is higher, the same locked water amount is achieved, and the locked water temperature is lower. Because the water heater can be used in different seasons and different regions, different external environments and different water inlet temperatures can be realized, and even if the locking water quantity is constant, the locking water temperature can be changed along with the change of the three conditions and any condition. Of course, the second corresponding relationship between the locking water amount and the locking water temperature is influenced by more than three factors, such as heating speed, water inlet and outlet flow rate and the like.
After a water heater manufacturer determines the second corresponding relation through experimental data, the second corresponding relation between the water locking quantity and the water locking temperature can be stored in the database under different conditions (the three conditions are different respectively), the second corresponding relation can be arranged in a table in advance, and the second corresponding relation can be searched in corresponding rows and columns according to specific conditions. When the second corresponding relation needs to be obtained, the second corresponding relation can be obtained through a parameter query mode. For example, a 50L water heater: when the water temperature is X and the actual temperature of the water tank is Y, TL (X, Y) is 50 ℃; TL (X1, Y1) 52 ℃.
In this embodiment, a table representing a second corresponding relationship between the locked water amount and the locked water temperature under the conditions is determined according to the conditions of the current water inlet temperature, the lowest water temperature of the outlet water, the current actual water temperature, and the like, and then the corresponding locked water temperature is determined according to the table and the locked water amount, so that the accuracy of the locked water temperature is ensured.
Further, based on the above embodiments, in a third embodiment of the water heater water amount control method of the present invention, the water heater water amount control method further includes:
and step S30, acquiring the current actual water temperature, determining the residual available water quantity of the water heater according to the current actual water temperature, and outputting the residual available water quantity.
The residual available water amount refers to the residual water amount which is actually remained at present and meets a certain water temperature condition, and the certain water temperature condition can refer to the lowest hot water temperature, namely the lowest water temperature required by the outlet of the water heater when people think water during bathing and specified by a manufacturer.
When a user sets a locking function, the user needs to know the residual available water volume of the water heater, and the residual available water volume can be displayed on a user interaction module of a shell of the water heater or can be displayed on a remote controller or a terminal application program connected with the water heater through a network. When a user sets a locking function, the user may not know the residual hot water amount, if the residual hot water amount is larger than the locking water amount, the water heater can be directly locked, if the residual hot water amount is smaller than the locking water amount, the water heater needs to heat the hot water in the current water tank, water outlet is most likely to stop at present, and even if the user needs water at present, the water heater cannot provide hot water because the locking function is started and the locking water amount is prior. To avoid this, it is preferable to output the current remaining amount of water to the user so that the user determines whether to lock, and the determination of the amount of locked water.
Meanwhile, if the user knows the remaining available water amount, the next water amount for use can be determined and controlled. If the water yield of 3 people that remain at present, then 2 individual water yield of locking, the people that next use can use the water yield of one person, like this, the user can carry out accurate assurance to the water heater water yield, is favorable to the user to make the water planning, promotes user experience.
Further, based on the above embodiments, in a fourth embodiment of the water quantity control method for a water heater of the present invention, the step S10 is preceded by:
and step S40, when the change of the current locked water temperature is detected, the current locked water temperature of the water heater is obtained again, and the step of obtaining the warning temperature difference value between the current locked water temperature and the current actual water temperature is executed.
After the user locks the water consumption of n (n >1) individuals, the current water yield is assumed to be zero, namely water outflow is stopped according to the difference value of the current actual water temperature and the current locked water temperature, and if the water consumption is unlocked later, because more than one person uses the remaining hot water, the former person still has excessive water, so that the latter person does not have enough water consumption. Therefore, the user has a need to change the locked water temperature at any time after locking.
In the embodiment, after the user changes the locking water temperature, once the water heater detects that the locking water temperature changes, the latest current locking water temperature can be obtained, the water outlet quantity of the water heater is controlled according to the latest current locking water temperature, so that the sufficient residual water quantity is ensured, the user can change the locking water temperature at any time, the reserved water quantity is changed, and the flexibility of water quantity control of the water heater is enhanced.
Further, based on the above embodiments, in a fifth embodiment of the water quantity control method for a water heater of the present invention, the step S12 is followed by:
step S50, judging the total water yield in a preset time period;
and step S51, if the total water yield in the preset time period is greater than a preset threshold value, stopping water outlet.
The user may still have a limited need for someone to use water after the locking function is turned on. If the water heater can be used for 5 people at present, only 2 people are locked, and 3 people are left, the water consumption of the children is limited to prevent the children from using the 3 people randomly and causing resource waste.
The preset time period and the preset threshold value can be defined by a user, the preset threshold value refers to the available water quantity, and if the total water yield of the water heater in the preset time period is greater than the preset threshold value, the water heater automatically stops water outlet; and if the total water yield in the preset time period is less than a preset threshold value, continuing to discharge water.
This embodiment can realize the user to the limited of the water consumption in the specific time interval of certain people, can make the water heater water consumption more accord with user's demand, and then promote user experience.
