Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water purifiers, and particularly to a water outlet control method of a water purifier. BACKGROUND

[0002] In daily use of the water purifier, the user hopes to take water at a large flow rate when taking water. Currently, water purifiers on the market are roughly divided into two types, namely, a water purifier without a hot water tank and a water purifier with a hot water tank. The water purifier without a hot water tank can only take water at a very small flow rate when the user needs to take boiling water due to the power limitation of the heating body. The water purifier with a hot water tank generally keeps the water in the hot water tank at a certain temperature, for example, the water temperature in the hot water tank is set to 80℃, which can guarantee the user's common functions. At this time, due to the high water temperature, the water can be heated faster after passing through the heating body than cold water, so the flow rate can be larger than that of the water purifier without a hot water tank.

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

[0005] According to an aspect of an embodiment of the present application, a water outlet control method of a water purifier is provided. The water purifier includes a hot water control device, a cold water control device, a proportional adjustment device and a heating device. The proportional adjustment device is arranged between the intersection water outlet of the hot water control device and the cold water control device and the water outlet of the water purifier. The heating device is arranged between the proportional adjustment device and the water outlet of the water purifier. The water outlet control method includes: obtaining a target water outlet temperature; when the target water outlet temperature is greater than the hot water temperature in the hot tank, calculating a hot water flow rate calculation value of the hot water control device when the actual water outlet temperature of the heating device under the maximum power state reaches the target water outlet temperature; determining the water temperature value in the proportional adjustment device and the maximum flow rate based on the hot water flow rate calculation value; when the target water outlet temperature is less than the hot water temperature in the hot tank, calculating the intersection proportion of the cold water and the hot water in the proportional adjustment device; and adjusting the hot water control device to the maximum hot water flow rate or adjusting the cold water control device to the maximum cold water flow rate according to the proportional interval where the intersection proportion is located.

[0006] Optionally, the determining the water temperature value and the maximum flow rate in the proportional mixing device based on the calculated hot water flow rate value comprises: controlling the hot water control device to output water alone, and selecting the smaller flow rate between the calculated hot water flow rate value and the maximum hot water flow rate of the hot water control device as the actual output water flow rate.

[0007] Optionally, the determining the water temperature value and the maximum flow rate in the proportional mixing device based on the calculated hot water flow rate value comprises: when the calculated hot water flow rate value is greater than the maximum hot water flow rate of the hot water control device, controlling the cold water device to be turned on and reducing the water temperature value in the proportional mixing device.

[0008] Optionally, the controlling the cold water device to be turned on and reducing the water temperature value in the proportional mixing device comprises: when the heating device is in a state where the actual output water temperature is equal to the target output water temperature at the maximum power, gradually reducing the hot water flow rate in the hot water control device and gradually increasing the cold water flow rate in the cold water device.

[0009] Optionally, during the gradual reduction of the hot water flow rate in the hot water control device and the gradual increase of the cold water flow rate in the cold water device, if the intersection flow rate of the cold water and the hot water in the proportional mixing device is less than the maximum hot water flow rate, the hot water control device is controlled to output water alone, and the maximum hot water flow rate is used as the actual output water flow rate.

[0010] Optionally, during the gradual reduction of the hot water flow rate in the hot water control device and the gradual increase of the cold water flow rate in the cold water device, if the intersection flow rate of the cold water and the hot water in the proportional mixing device is greater than the maximum hot water flow rate, and the hot water flow rate reaches a preset hot water flow rate interval and the cold water flow rate reaches a preset cold water flow rate interval, the intersection flow rate is used as the actual output water flow rate.

[0011] Optionally, the preset hot water flow rate interval is 15%-100% of the maximum hot water flow rate, and the preset cold water flow rate interval is 25%-100% of the maximum cold water flow rate.

[0012] Optionally, the calculating the intersection proportion of the cold water and the hot water in the proportional mixing device comprises: obtaining a cold water temperature; and when the heating device is in a state of stopping heating, calculating the intersection proportion when the actual output water temperature reaches the target output water temperature based on the hot water temperature and the cold water temperature.

[0013] Optionally, the adjusting the hot water control device to the maximum hot water flow rate or adjusting the cold water control device to the maximum cold water flow rate according to the mixing ratio comprises: determining whether the mixing ratio is greater than the ratio of the maximum cold water flow rate to the maximum hot water flow rate; when the mixing ratio is greater than the ratio of the maximum cold water flow rate to the maximum hot water flow rate, adjusting the cold water control device to the maximum cold water flow rate and increasing the hot water flow rate of the hot water control device until the target outlet water temperature is reached; when the mixing ratio is less than the ratio of the maximum cold water flow rate to the maximum hot water flow rate, adjusting the hot water control device to the maximum hot water flow rate and adjusting the cold water flow rate of the cold water control device based on the target outlet water temperature.

[0015] In the present application, when the target outlet water temperature is greater than the hot water temperature in the hot tank, the hot water flow rate calculation value of the hot water control device is calculated when the actual outlet water temperature of the heating device reaches the target outlet water temperature in the maximum power state. As the target outlet water temperature approaches the hot water temperature in the hot tank, the temperature difference between the target outlet water temperature and the hot water temperature in the hot tank becomes smaller and smaller. Based on p = cmΔT, the hot water flow rate calculation value becomes larger and larger when the heating power is kept maximum. If the hot water flow rate calculation value does not reach the maximum hot water flow rate, the hot water flow rate is used for outlet water. If the hot water flow rate calculation value is greater than the maximum hot water flow rate, the maximum hot water flow rate or the cold-hot mixing outlet water can be used, and the larger one can be selected for outlet water from the maximum hot water flow rate and the cold-hot mixing outlet water flow rate, so as to reach the maximum flow rate outlet water condition while meeting the target outlet water temperature. When the target outlet water temperature is less than the hot water temperature in the hot tank, the outlet water is performed according to the calculated cold water and hot water ratio. In order to adjust the actual outlet water flow rate to the maximum, the cold water control device or the hot water control device is adjusted to the maximum, and the flow rate of the other control device is adjusted to match the calculated cold water and hot water ratio, so as to obtain the maximum actual outlet water flow rate. Therefore, at any target outlet water temperature, the maximum flow rate corresponding to the target outlet water temperature can be selected for outlet water, which can greatly improve the user experience.

[0023] According to an aspect of the present application, a water outlet control method of a water purifier is provided, as shown in Figure 1As shown, the water purifier comprises a hot water control device 10, a cold water control device 20, a proportional adjustment device 30, a heating device 40 and a hot tank 50, the proportional adjustment device 30 is arranged between the intersection outlet of the hot water control device 10 and the cold water control device 20 and the outlet of the water purifier, the heating device 40 is arranged between the proportional adjustment device 30 and the outlet of the water purifier, and Figure 2 As shown, the water outlet control method comprises:

[0024] S10. Obtain a target water outlet temperature.

[0025] In this embodiment, the target water temperature can be a target water outlet temperature input by a user, for example, the user selects a water temperature of 45℃, 60℃, 85℃, 90℃, 100℃, etc., or can be selected by a water outlet use function button, for example, a function button for milk, tea, coffee, etc., or can be a fixed water temperature, for example, a fixed water outlet temperature of 45℃, 60℃, 85℃, 90℃, 100℃. Taking the user selection as an example, the user can select the target water outlet temperature demand information through the operation panel of the water purifier, and the controller receives the demand information of the user, and obtains the target water outlet temperature by decoding the information.

[0026] 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℃, 80℃, etc. After obtaining the target water outlet temperature, the target water outlet temperature and the hot water temperature in the hot tank 50 are compared, when the target water outlet temperature is greater than the hot water temperature in the hot tank 50, step S30 is entered, and when the target water outlet temperature is less than the hot water temperature in the hot tank 50, step S50 is entered.

[0027] S30. Calculate the hot water flow rate calculation value of the hot water control device 10 when the actual water outlet temperature of the heating device in the maximum power state reaches the target water outlet temperature. In the case that 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 water outlet flow rate, and in the case that the heating power is constant, the higher the water temperature in the proportional adjustment device 30, the greater the water outlet flow rate.

[0028] As an exemplary embodiment, when the target water outlet temperature is greater than the hot water temperature in the hot tank 50, the actual water outlet flow rate is the highest in the case of using only the hot tank 50 and the maximum heating power.

[0029] In the case of water out of the hot tank 50, the water temperature in the proportional adjusting device 30 is the temperature in the hot tank 50, thus, in the case of the heating device 40 at the maximum power, the actual water out temperature is stabilized at the target water out temperature based on the temperature difference between the target water out temperature and the hot water temperature in the hot tank 50, the theoretical flow rate of the hot water control device 10, i.e. the hot water flow rate calculation value. Specifically, p = cmΔT, wherein 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 target water out temperature and the hot water temperature in the hot tank 50, and m is the hot water flow rate calculation value, which is calculated in the case of P maximum.

[0030] S40. Determine the water temperature value in the proportional adjusting device and the maximum flow rate based on the hot water flow rate calculation value. In the case of the target water out temperature greater than the hot water temperature in the hot tank 50, the greater the target water out temperature, the smaller the hot water flow rate calculation value, and the closer the target water out temperature to the hot water temperature in the hot tank 50, the greater the hot water flow rate calculation value, thus, in the case of the target water out temperature large enough, the hot water flow rate calculation value will be small, which can meet the condition of water out only through the hot water control device 10, and the actual water out temperature reaches the target water out temperature in the case of the maximum heating power, at which time the water temperature value in the proportional adjusting device 30 is the hot water temperature in the hot tank 50, and the hot water control device 10 out water according to the hot water flow rate calculation value, i.e. the maximum flow rate of the proportional adjusting device 30.

[0031] As an exemplary embodiment, as the target water out temperature approaches the hot water temperature in the hot tank 50, the temperature difference between the target water out temperature and the hot water temperature in the hot tank 50 becomes smaller and smaller, and based on p = cmΔT, in the case of the heating power remaining maximum, thus, the hot water flow rate calculation value will become larger and larger until the hot water flow rate calculation value equals the maximum hot water flow rate of the hot tank 50. In this target water out temperature condition, only the hot water control device 10 is turned on to out water at the maximum hot water flow rate, and the heating power is maximum. If the target water out temperature is lower than this target water out temperature, the hot water flow rate calculation value will be greater than the maximum hot water flow rate of the hot tank 50, and cold water can be added to reduce the water temperature in the proportional adjusting device 30 to find the maximum flow rate, i.e. determine the water temperature in the proportional adjusting device 30 and the maximum flow rate based on the hot water flow rate calculation. Only hot water can also be out, i.e. the water temperature value in the proportional adjusting device 30 is the hot water temperature in the hot tank 50, and the hot water control device 10 is controlled to out water at the maximum hot water flow rate.

[0032] S50. Calculate the intersection proportion of cold water and hot water in the proportional adjusting device. As an exemplary embodiment, in the case of the target water out temperature less than the hot water temperature in the hot tank 50, cold and hot intersection water out can be performed without heating to obtain the target water out temperature.

[0033] For example, the cold water temperature is obtained, which can be room temperature, for example, 25℃, or other temperature, for example, 20℃, 30℃, etc.

[0034] When the heating device 40 is in the 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. For example, 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 S 冷 +S 热 =S 交汇 and S 冷 ×T 冷 +S 热 ×T 热 =S 交汇 ×T 交汇 ; S 冷 is obtained: 热 =(T 热 -T 交汇 ):(T 交汇 -T 冷 ); wherein S 冷 is the cold water flow rate, S 热 is the hot water flow rate, S 交汇 is the intersection flow rate, T 冷 is the cold water temperature, T 热 is the hot water temperature, and T 交汇 is the intersection temperature.

[0035] S60. The hot water control device is adjusted to the maximum hot water flow rate according to the proportion interval of the intersection ratio, or the cold water control device is adjusted to the maximum cold water flow rate. 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.

[0036] The outlet water is obtained according to the calculated cold water and hot water ratio, in order to adjust the actual outlet water flow rate to the maximum, the ratio of the cold water control device 20 or the hot water control device 10 is adjusted to the maximum, and the flow rate of the other control device is adjusted to match the value calculated by the cold water and hot water ratio to obtain the maximum actual outlet water flow rate.

[0037] In the present application, when the target outlet water temperature is greater than the hot water temperature in the hot tank 50, the hot water flow rate calculation value of the hot water control device 10 is calculated when the actual outlet water temperature of the heating device 40 reaches the target outlet water temperature in the maximum power state. As the target outlet water temperature approaches the hot water temperature in the hot tank 50, the temperature difference between the target outlet water temperature and the hot water temperature in the hot tank 50 becomes smaller and smaller, and based on p = cmΔT, the hot water flow rate calculation value becomes larger and larger when the heating power remains maximum. If the hot water flow rate calculation value does not reach the maximum hot water flow rate, the hot water flow rate is used for outlet water, if the hot water flow rate calculation is greater than the maximum hot water flow rate, the maximum hot water flow rate can be used, or cold and hot water can be mixed for outlet water, and the larger one can be selected for outlet water from the maximum hot water flow rate and the cold and hot water mixing outlet water flow rate, so as to meet the target outlet water temperature and achieve the maximum flow rate outlet water working condition. When the target outlet water temperature is less than the hot water temperature in the hot tank 50, the calculated cold water and hot water ratio is used for outlet water. In order to adjust the actual outlet water flow rate to the maximum, the ratio of the cold water control device 20 or the hot water control device 10 is adjusted to the maximum, and the flow rate of the other control device is adjusted to match the calculated cold water and hot water ratio to obtain the maximum actual outlet water flow rate. Therefore, at any target outlet water temperature, the maximum flow rate corresponding to the target outlet water temperature can be selected for outlet water, which can greatly improve the user experience.

[0038] In the present embodiment, the control device with a large flow rate ratio can be adjusted to the maximum, and the flow rate of the other control device is adjusted to match the calculated cold water and hot water ratio.

[0039] For example, when the cold water ratio is large, it means that more cold water is needed, and the target outlet water 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 the hot water flow rate is adjusted to stabilize the mixed water temperature at the target water temperature, and the actual outlet water flow rate obtained at this time is the maximum.

[0040] When the hot water ratio is large, it means that more hot water is needed. In order to maximize the actual outlet water flow rate, the hot water ratio can be adjusted to the maximum, the minimum flow rate of the cold pump is determined according to the maximum flow rate of the hot water control device 10 and the target outlet water temperature, the flow rate of the water control device is gradually increased based on the maximum flow rate of the hot water control device 10 and the minimum flow rate of the cold pump, and the heating device 40 is turned on. Under the premise that the actual outlet water temperature is equal to the target outlet water 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 outlet water flow rate obtained at the current target outlet water temperature is the maximum.

[0041] For example, it is determined 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, the cold water control device 20 is adjusted to the maximum cold water flow rate, the hot water flow rate of the hot water control device 10 is increased until the target outlet water 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, the hot water control device 10 is adjusted to the maximum hot water flow rate, and the cold water flow rate of the cold water control device 20 is adjusted based on the target outlet water temperature.

[0042] If S 冷 : S 热 > S 冷max : S 热max ;

[0043] then it means that cold water needs more, at this time, S 冷 = S 冷max , and S 热 = S 冷 × (T 交汇 - T 冷 ) / (T 热 - T 交汇 ) is calculated; this working condition represents that the cold water is maximum, and the intersection is mixed to the target temperature, at this time, the hot water control device 10 cannot be increased in flow rate, which is the maximum outlet water flow rate.

[0044] If S 冷 : S 热 < S 冷max : S 热max ;

[0045] then it means that hot water needs more, at this time, S 热 = S 热max， , and S 冷 = S 冷 × (T 热 - T 混交汇 ) / (T 混交汇 - T 冷 ) is calculated; this working condition represents that the hot water is maximum, and the intersection is mixed to the target temperature, at this time, the cold water flow rate can be appropriately increased, and the heating power will be increased, when the heating power is increased to the maximum or the cold water flow rate reaches the maximum, at this time, the flow rate is maximum.

[0046] As an exemplary embodiment, when the hot water flow rate calculation value is greater than the maximum hot water flow rate, the water outlet is performed at the maximum hot water flow rate. Therefore, the water outlet of the hot water control device 10 is controlled separately, and the smaller flow rate between the hot water flow rate calculation value and the maximum hot water flow rate of the hot water control device 10 is selected as the actual water outlet flow rate.

[0047] As an exemplary embodiment, when the hot water flow rate calculation value is greater than the maximum hot water flow rate, the water outlet is performed at the maximum hot water flow rate. Therefore, the water outlet of the hot water control device 10 is controlled separately, and the smaller flow rate between the hot water flow rate calculation value and the maximum hot water flow rate of the hot water control device 10 is selected as the actual water outlet flow rate.

[0048] As another alternative embodiment, since the water outlet at the maximum hot water flow rate can not be the maximum water outlet flow rate corresponding to the current target water outlet temperature, the cold water control device 20 can also be considered to be turned on, and the water temperature in the proportional adjustment device 30 is reduced to perform the cold-hot water mixing water outlet while maintaining the maximum heating power.

[0049] When the preset condition of the stable mixing water outlet is reached, the mixing flow rate of the mixing water outlet and the maximum hot water flow rate can be compared, and the maximum water outlet flow rate is selected as the actual water outlet flow rate.

[0050] As an exemplary embodiment, controlling the cold water control device 20 to be turned on and reducing the water temperature in the proportional adjustment device 30 to perform the cold-hot water mixing water outlet includes: gradually reducing the mixing water temperature while maintaining the actual water outlet temperature equal to the target water outlet temperature at the maximum power of the heating device 40, obtaining the mixing flow rate, and performing the water outlet at the mixing flow rate as the actual water outlet flow rate. In this embodiment, since the calculated hot water flow rate calculation value is already greater than the maximum flow rate of the hot water control device 10, the mixing water temperature can be gradually reduced, and the mixing flow rate can be gradually reduced from the hot water flow rate calculation value to seek the optimal water outlet flow rate.

[0051] In this embodiment, the mixing water temperature can be gradually reduced 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.

[0052] Alternatively, the hot water flow rate in the hot water control device 10 can be gradually reduced and the cold water flow rate in the cold water device can be gradually increased while maintaining the actual water outlet temperature equal to the target water outlet temperature at the maximum power of the heating device 40.

[0053] Therefore, in the process of gradually reducing the hot water flow rate in the hot water control device 10 and gradually increasing the cold water flow rate in the cold water control device, the junction flow rate is calculated gradually and compared with the maximum hot water flow rate. When the condition of stopping reducing the junction water temperature is not reached, if the junction flow rate of the cold water and the hot water in the proportional adjustment device 30 is less than the maximum hot water flow rate, the water outlet of the hot water control device 10 is controlled alone, and the maximum hot water flow rate is taken as the actual water outlet flow rate.

[0054] If the junction flow rate of the cold water and the hot water in the proportional adjustment device 30 is greater than the maximum hot water flow rate when the condition of stopping reducing the junction water temperature is reached, the junction flow rate is taken as the actual water outlet flow rate.

[0055] As an exemplary embodiment,

[0056] In the process of reducing the junction water temperature, generally, the water outlet flow rates of the cold water control device 20 and the hot water control device 10 have stable and linear reasonable flow rate intervals, for example, the reasonable flow rate interval of the cold water control device 20 is 25%-100% of the maximum cold water flow rate, and the reasonable flow rate interval of the hot water control device 10 is 15%-100% of the maximum hot water flow rate.

[0057] Therefore, in order to ensure the water outlet temperature, in the process of gradually reducing the hot water flow rate in the hot water control device 10 and gradually increasing the cold water flow rate in the cold water control device, it can be determined whether the cold water flow rate reaches the preset cold water flow rate interval and whether the hot water flow rate reaches the preset hot water flow rate interval.

[0058] If the junction flow rate of the cold water and the hot water in the proportional adjustment device 30 is greater than the maximum hot water flow rate, and the hot water flow rate reaches the preset hot water flow rate interval and the cold water flow rate reaches the preset cold water flow rate interval, the junction flow rate is taken as the actual water outlet flow rate.

[0059] At this time, the maximum water outlet flow rate that can be stably ensured at the current target water outlet temperature can be ensured.

[0060] In the process of gradually reducing the junction water temperature, if the hot water flow rate calculated by the hot water control device 10 in the reducing 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 the embodiment, the hot water flow rate is also 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, the junction water temperature is continuously reduced, that is, the hot water flow rate is continuously reduced and the cold water flow rate is continuously increased, if the junction flow rate is reduced to less than the maximum flow rate of the hot water control device 10, and the hot water flow rate and / or the cold water flow rate are still outside the preset range of one, it is indicated that the maximum junction flow rate of the hot and cold water junction outlet water is less than the maximum hot water flow rate of the single hot water control device 10, and the maximum hot water flow rate of the single hot water control device 10 is used at this time.

[0061] Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be realized by means of software and the necessary general hardware platform, and of course, it can also be realized by hardware, but in many cases, the former is a better embodiment.
