Description

Technical Field

[0001] The present application relates to the technical field of water purifiers, and in particular to a water outlet control method for a water purifier. Background Art

[0002] In the daily life use of water purifiers, users hope to be able to draw water at a high flow rate when taking water. Currently, there are roughly two types of water purifiers on the market, namely, water purifiers without hot water tanks and water purifiers with hot water tanks. Due to the power limitation of the heating element, water purifiers without hot water tanks can only deliver water at a very low flow rate when users need boiling water. Water purifiers with hot water tanks generally keep the water in the hot water tank warm at a certain temperature. For example, the water temperature in the hot water tank is set to maintain at 80°C. This temperature can ensure the functions commonly used by users. At this time, due to the high water temperature, after passing through the heating element, it can be heated faster than cold water, so the flow rate can be greater than that without a hot water tank.

[0003] Different target water outlet temperatures have different requirements for the heating device, cold water control device and hot water control device. Therefore, how to achieve the maximum water outlet flow rate at any target water outlet temperature becomes a technical problem that needs to be solved urgently. Summary of the invention

[0008] Optionally, when the second hot water flow rate is outside the preset hot water flow rate range and / or the cold water flow rate of the cold water control device is outside the preset cold water flow rate range, the intersection water temperature continues to be lowered until the intersection flow rate is less than the maximum hot water flow rate, or the second hot water flow rate is within the preset hot water flow rate range, and the cold water flow rate of the cold water control device is within the preset cold water flow rate range.

[0009] Optionally, when the intersection flow rate is less than the maximum hot water flow rate, the maximum hot water flow rate is used as the actual water outlet flow rate, and the heating power of the heating device is lowered.

[0010] Optionally, the preset hot water flow rate interval is 15%-100% of the maximum hot water flow rate; the preset cold water flow rate interval is 25%-100% of the maximum cold water flow rate.

[0024] Or other steps or units inherent to the device.

[0025] According to one aspect of the present application, a water outlet control method for a water purifier is proposed, such as Figure 1 As shown, the water purifier includes a hot water control device 10, a cold water control device 20, a ratio adjustment device 30 and a heating device 40. The ratio adjustment device 30 is arranged between the intersection of the hot water control device 10 and the cold water control device 20 and the water outlet of the water purifier, and the heating device 40 is arranged between the ratio adjustment device 30 and the water outlet of the water purifier. Figure 2 As shown, the water outlet control method includes:

[0026] S10. Obtain target outlet water temperature.

[0027] In this embodiment, the acquisition of the target water temperature may be the target outlet water temperature input by the user, for example, the user selects a water temperature of 45°C, 60°C, 85°C, 90°C, 100°C, etc., or may be selected through a water outlet purpose function button, for example, a function button for making milk, tea, coffee, etc., or may be a fixed outlet water temperature, for example, a fixed outlet water temperature of 45°C, 60°C, 85°C, 90°C, 100°C. Taking user selection as an example, the user may select the target outlet water temperature demand information through the operation panel on the water purifier, and after the controller receives the user's demand information, it obtains the target outlet water temperature by decoding the information.

[0028] S20. Determine whether the target water outlet temperature is greater than the hot water temperature in the hot tank. In this embodiment, the hot water temperature in the hot tank 50 is preset in advance, for example, the stable hot water temperature in the hot tank 50 can be 50°C, 80°C, etc. After obtaining the target water outlet temperature, compare the target water outlet temperature with the hot water temperature in the hot tank 50. When the target water outlet temperature is greater than the hot water temperature in the hot tank 50, proceed to step S30.

[0029] S30. Calculate the first hot water flow rate of the hot water control device when the actual outlet water temperature of the heating device reaches the target outlet water temperature under the maximum power state. When the water temperature in the proportional adjustment device 30 is constant, that is, the water temperature before entering the heating device 40 is constant, the greater the heating power, the greater the outlet water flow rate. When the heating power is constant, the higher the water temperature in the proportional adjustment device 30, the greater the outlet water flow rate.

[0030] As an exemplary embodiment, when the target outlet water temperature is greater than the hot water temperature in the hot tank 50, the actual outlet water flow rate is the highest when only the hot tank 50 is used to outlet water and the heating power is maximum.

[0031] When the hot tank 50 is discharging water, the water temperature in the proportional adjustment device 30 is the temperature in the hot tank 50. Therefore, when the heating device 40 is at maximum power, the actual outlet water temperature is obtained based on the temperature difference between the hot water temperature in the hot tank 50 and the target temperature, and the theoretical flow rate of the hot water control device 10 is the first hot water flow rate when the actual outlet water temperature is stabilized at the target outlet water temperature. Specifically, p=cmΔT, where P is the heating power of the heating device 40, c is the specific heat capacity of water, ΔT is the temperature difference between the hot water temperature in the hot tank 50 and the target outlet water temperature, and m is the first hot water flow rate, which is calculated when P is maximum.

[0032] S40. Determine whether the first hot water flow rate is less than the maximum hot water flow rate of the hot water control device. In this embodiment, the hot water control device 10 takes a hot water pump as an example, and the maximum hot water flow rate is the rated flow rate of the hot water pump. After calculating the first hot water flow rate, compare the first hot water flow rate with the maximum hot water flow rate. When the first hot water flow rate is less than the maximum hot water flow rate of the hot water control device 10, proceed to step S50. When the first hot water flow rate is greater than the maximum hot water flow rate, proceed to step S60.

[0033] S50. Use the first hot water flow rate as the actual water outlet flow rate to discharge water. As an exemplary embodiment, if the first hot water flow rate is less than the maximum hot water flow rate of the hot water control device 10, it is considered that when the heating device 40 is at maximum power, if water is discharged at the maximum hot water flow rate, the actual water outlet temperature will be less than the target water outlet temperature. Therefore, using the first hot water flow rate as the actual water outlet flow rate, the actual water outlet temperature can reach the target water outlet temperature under the maximum water outlet flow rate.

[0034] S60. Use the maximum hot water flow rate as the actual water flow rate, and lower the heating power of the heating device; or control the cold water control device to open and conduct hot and cold water discharge. As an exemplary embodiment, if the first hot water flow rate is greater than the maximum hot water flow rate, if the hot water control device 10 is used alone to discharge water, the maximum actual water flow rate is the maximum water flow rate of the hot water control device 10. Therefore, the heating power of the heating device 40 can be reduced, and the maximum hot water flow rate of the hot water control device 10 is used as the actual water flow rate.

[0035] It is also possible to consider lowering the intersection water temperature, that is, turning on the cold water control device 20 to conduct cold and hot water intersection. Based on P=cmΔt, after turning on the cold water control device 20, the water temperature in the proportional adjustment device 30 decreases, that is, Δt increases. Under the premise that the power is maximum power, its actual water outlet flow rate is lower than the calculated first hot water flow rate, but the calculated first hot water flow rate is already greater than the maximum flow rate of the hot water control device 10. Therefore, the actual flow rate of the cold and hot water intersection may be greater than the actual maximum hot water flow rate. Therefore, the cold and hot water intersection can be used to determine the actual water outlet flow rate.

[0036] In the present application, when the target water outlet temperature is greater than the hot water temperature in the hot tank 50, the first hot water flow rate of the hot water control device 10 is calculated when the actual water outlet temperature of the heating device 40 reaches the target water outlet temperature under the maximum power state. If the first hot water flow rate does not reach the maximum hot water flow rate, water is discharged at the first hot water flow rate. If the first hot water flow rate is greater than the maximum hot water flow rate, the maximum hot water flow rate or the cold and hot junction water outlet can be used, and the larger one can be selected between the maximum hot water flow rate and the cold and hot junction water outlet flow rate for water discharge, so as to achieve the working condition of water discharge at the maximum flow rate while meeting the target water outlet temperature. Therefore, at any target water outlet temperature, the maximum flow rate corresponding to the target water outlet temperature can be selected for water discharge, which can greatly improve the user experience.

[0037] As an optional embodiment, controlling the cold water control device 20 to turn on and conduct cold and hot water confluence includes: when the heating device 40 is at maximum power and the actual water outlet temperature is maintained equal to the target water outlet temperature, the confluence water temperature is gradually reduced to obtain the confluence flow rate, and the confluence flow rate is used as the actual water outlet flow rate for water outlet. In this embodiment, since the calculated first hot water flow rate is greater than the maximum flow rate of the hot water control device 10, the confluence water temperature can be gradually reduced so that the confluence flow rate is gradually reduced from the first hot water flow rate to seek the optimal water outlet flow rate.

[0038] In this embodiment, the intersection water temperature can be lowered by setting the actual flow rate of the hot water control water outlet to the maximum hot water flow rate and gradually increasing the flow rate of the cold water control device 20. Optionally, in the process of gradually lowering the intersection water temperature, as the intersection water temperature decreases, the second hot water flow rate of the hot water control device 10 decreases, the intersection flow rate decreases, and the cold water flow rate of the cold water control device 20 increases.

[0039] Until the temperature difference between the intersection water temperature and the target water outlet temperature can satisfy the actual water outlet temperature to reach the target water outlet temperature when the heating power of the heating device 40 is maximum, the intersection flow rate at this time can be used as the actual water outlet flow rate.

[0040] Generally, the water outlet flow rates of the cold water control device 20 and the hot water control device 10 often have a stable and linear reasonable flow rate range. For example, the reasonable flow rate range of the cold water control device 20 is 25%-100% of the maximum cold water flow rate, and the reasonable flow rate range of the hot water control device 10 is 15%-100% of the maximum hot water flow rate. Therefore, in this embodiment, in the process of gradually reducing the intersection water temperature, the intersection flow rate gradually decreases. Therefore, when the intersection flow rate is not reduced to the maximum hot water flow rate, that is, the intersection flow rate is greater than the maximum hot water flow rate, if the cold water control device 20 and the hot water control device 10 are both in the reasonable flow rate range at this time, it is considered that when the current intersection flow rate is used as the water outlet flow rate, the actual water outlet flow rate is the maximum.

[0041] Therefore, in the process of gradually reducing the intersection water temperature, it is determined whether the intersection flow rate is still greater than the maximum hot water flow rate. If it is still greater, it is further determined whether the second hot water flow rate of the hot water control device 10 is within the preset hot water flow rate interval, and whether the cold water flow rate of the cold water control device 20 is within the preset cold water flow rate interval;

[0042] When the second hot water flow rate is within the preset hot water flow rate interval, and the cold water flow rate of the cold water control device 20 is within the preset cold water flow rate interval, the intersection water temperature is stopped from being lowered, and the intersection flow rate is used as the actual water outlet flow rate for water outlet. At this time, under the premise that the actual water outlet temperature is equal to the target water outlet temperature, the actual water outlet flow rate is the maximum.

[0043] In the process of gradually lowering the intersection water temperature, if the second hot water flow rate calculated by the hot water control device 10 during the lowering process is outside the preset hot water flow rate range and / or the cold water flow rate of the cold water control device 20 is outside the preset cold water flow rate range, in this embodiment, the second hot water flow rate is still greater than the maximum hot water flow rate or the cold water flow rate is less than the minimum value of the preset cold water flow rate range, then the intersection water temperature continues to be lowered, that is, the second hot water flow rate continues to be lowered and the cold water flow rate is increased. If the intersection flow rate is reduced to less than the maximum flow rate of the hot water control device 10, the second hot water flow rate and / or the cold water flow rate is still outside the preset range for one, then the maximum intersection flow rate of the cold and hot water intersection water outlet will be less than the maximum hot water flow rate when the hot water control device 10 is alone, and at this time, the maximum hot water flow rate of the hot water control device 10 is used to discharge water.

[0044] See also Figure 3 As shown, the water outlet control method of the water purifier also includes:

[0045] S10. Obtain target outlet water temperature.

[0046] S20. Determine whether the target outlet water temperature is greater than the hot water temperature in the hot tank. When the target outlet water temperature is less than the hot water temperature in the hot tank, proceed to step S70.

[0047] S70. Calculate the intersection ratio of the cold water flow rate and the hot water flow rate. As an exemplary embodiment, when the target outlet water temperature is lower than the hot water temperature in the hot tank 50, the cold and hot water can be combined to obtain the target outlet water temperature without heating.

[0048] For example, the cold water temperature is obtained. The cold water temperature may be room temperature, for example, 25°C, or other

[0049] Temperature, such as 20℃, 30℃, etc.

[0050] When the heating device 40 is in a state of stopping heating, the intersection ratio of the cold water flow rate and the hot water flow rate when the actual outlet water temperature reaches the target outlet water temperature is calculated according to the hot water temperature and the cold water temperature. 冷 +S 热 =S 交汇 and S 冷 ×T 冷 +S 热 ×T 热 =S 交汇 ×T 交汇 ; get S 冷 :S 热 =(T 热 -T 交汇 ):(T 交汇 -T 冷 ), where S 冷 is the cold water flow rate, S 热 is the hot water flow rate, S 交汇 is the intersection velocity, T 冷 is the cold water temperature, T 热 is the hot water temperature, T 交汇 is the intersection temperature.

[0051] S80. Adjust the hot water control device to the maximum hot water flow rate, or adjust the cold water control device to the maximum cold water flow rate according to the ratio interval of the intersection ratio. In this embodiment, the maximum cold water flow rate of the cold water control device 20 can be 1200ml / min, and the maximum hot water flow rate of the hot water control device 10 can be 2000ml / min. Of course, other rated flow rates are also applicable in this embodiment, for example, the maximum cold water flow rate can be 1500ml / min, and the maximum hot water flow rate can be 1800ml / min; the maximum cold water flow rate can be 2000ml / min, and the maximum hot water flow rate can be 1500ml / min, etc.

[0052] Water is discharged according to the calculated ratio of cold water and hot water. In order to adjust the actual water outlet flow rate to the maximum, the ratio of the cold water control device 20 or the hot water control device 10 can be adjusted to the maximum, and then the flow rate of the other control device is adjusted to match the value calculated to obtain the cold water and hot water ratio, so as to obtain the maximum actual water outlet flow rate.

[0053] In this embodiment, the control device with a larger flow rate ratio can be adjusted to the maximum, so that the flow rate of another control device matches the calculated ratio of cold water to hot water.

[0054] For example, when the cold water ratio is large, it may mean that more cold water is needed and the target water outlet temperature is too low. Without the need for the heating device 40 to work, the cold water control device 20 needs to reach the maximum flow rate to meet the target temperature. Therefore, the cold water ratio can be adjusted to the maximum, and then the hot water flow rate can be adjusted so that the intersection water temperature is stabilized at the target water temperature. At this time, the actual water outlet flow rate is the maximum.

[0055] When the proportion of hot water is large, it means that more hot water is needed. In order to maximize the actual water outlet flow rate, the proportion of hot water can be adjusted to the maximum. According to the maximum flow rate of the hot water control device 10 and the target water outlet temperature, the minimum flow rate of the cold pump is determined. On the basis of the minimum flow rate, the maximum flow rate of the hot water control device 10 is kept unchanged, and the flow rate of the water control device is gradually increased. At the same time, the heating device 40 is turned on. Under the premise that the actual water outlet temperature is equal to the target water outlet temperature, the heating power of the heating device 40 is adjusted until the cold water flow rate reaches the maximum or the heating power rises to the maximum. At this time, the actual water outlet flow rate obtained is the maximum at the current target water outlet temperature.

[0056] Exemplarily, determine whether the intersection ratio is greater than the ratio of the maximum cold water flow rate to the maximum hot water flow rate; when the intersection ratio is greater than the ratio of the maximum cold water flow rate to the maximum hot water flow rate, modulate the cold water control device 20 to the maximum cold water flow rate, and increase the hot water flow rate of the hot water control device 10 until the target water outlet temperature is reached; when the intersection ratio is less than the ratio of the maximum cold water flow rate to the maximum hot water flow rate, adjust the hot water control device 10 to the maximum hot water flow rate, and adjust the cold water flow rate of the cold water control device 20 based on the target water outlet temperature.

[0057] If S 冷 :S 热 >S cold max: S 热max ;

[0058] This means that more cold water is needed. In this case, set S 冷 =S 冷max , calculate S 热 =S 冷 ×(T 交汇 -T 冷 ) / (T 热 -T 交汇 ); This working condition represents that the cold water is the largest and converges to the target temperature. At this time, the hot water control device 10 cannot increase the flow rate. This is the maximum water outlet flow rate.

[0059] If S 冷 :S 热 冷max :S 热max ;

[0060] ​This means that more hot water is needed. In this case, set S 热 =S 热max , calculate S 冷 =S 冷 ×(T 热 -T 混交汇 ) / (T 混交汇 -T 冷 ); This working condition means that the hot water is at its maximum and the mixture converges to the target temperature. At this time, the cold water flow rate can be appropriately increased, and the heating power will increase. When the heating power rises to the maximum or the cold water flow rate reaches the maximum, the flow rate is at its maximum.
