Embodiments of the present disclosure are described in detail below, examples of which are illustrated in the drawings. The same or similar elements are denoted by same reference numerals in different drawings unless indicated otherwise. The embodiments described herein with reference to drawings are explanatory, and used to generally understand the present disclosure. The embodiments shall not be construed to limit the present disclosure.
A water drinking apparatus and a method for detecting a water discharging state of a water drinking apparatus provided by embodiments of the present disclosure are described below with reference to the drawings.
At S1, a water temperature range of cooled water of the water cooling device is acquired, and a plurality of temperature points is acquired according to the water temperature range.
In an embodiment of the present disclosure, the water drinking apparatus includes a water cooling device and a cooled water mechanical faucet, and the water of the water drinking apparatus is cooled by the water cooling device and then flows out through the cooled water mechanical faucet. The water drinking apparatus further includes a temperature detector configured to detect the water temperature of the cooled water of the water cooling device, and the temperature detector may be disposed inside the water cooling device.
Specifically, firstly, the water temperature range [Tmin, Tmax] of the cooled water may be determined according to the refrigeration performance of the water cooling device, and after the water temperature range [Tmin, Tmax] is determined, a plurality of temperature points to be recorded can be determined, for example, every temperature point is recorded with an interval of 1° C., and the number of temperature points to be recorded in the water temperature range [Tmin, Tmax] is Tmax-Tmin.
At S2, a rising reference time, a falling reference time, a rising reference adjustment value, and a falling reference adjustment value of each temperature point are acquired.
Specifically, when the water drinking apparatus is powered on and a whole machine test is performed, the temperature of the cooled water of the water cooling device is detected by the temperature detector, and the rising time and the falling time of each temperature point are recorded. In other words, when the water temperature is increased, the rising time of each temperature point is recorded, and when the water temperature is decreased, the falling time of each temperature point is recorded. It should be noted that each temperature point has two adjacent temperature points, the rising time of a temperature point refers to the time when the temperature point is increased to a larger temperature point of two adjacent temperature points, and the falling time of a temperature point refers to the time when the temperature point is decreased to a smaller temperature point of the two adjacent temperature points. For example, there are three consecutive temperature points T1, T2 and T3, in which T1<T2<T3, such that the rising time of the temperature point T2 refers to the time when the temperature point T2 is increased to the temperature point T3, and the falling time of the temperature point T2 refers to the time when the temperature point T2 is decreased to the temperature point T1.
Therefore, the whole machine test is performed for N times to record N rising times and N falling times of the temperature points, N is a positive integer. A rising reference time, a falling reference time, a rising reference adjustment value and a falling reference adjustment value of each temperature point are acquired according to the N rising times and the N falling times of the temperature points. For example, according to the cooling test of the whole machine, the following set of values may be determined.
When the temperature is decreased, the falling reference times of a plurality of temperature points may be M0, M1, M2, . . . , respectively.
When the temperature is decreased, the falling reference adjustment values of a plurality of temperature points may be P0, P1, P2, . . . , respectively.
When the temperature is increased, the rising reference times of a plurality of temperature points may be N0, N1, N2, . . . , respectively.
When the temperature is increased, the rising reference adjustment values of a plurality of temperature points may be Q0, Q1, Q2, . . . , respectively.
It should be understood that the water drinking apparatus is not in a water discharging state during the whole machine test.
At S3, a water temperature of the cooled water of the water cooling device is detected in real time, and an actual rising time and an actual falling time of each temperature point are acquired according to the water temperature of the cooled water of the water cooling device.
Specifically, in the case that the water drinking apparatus is powered on and is working, when the water temperature is changed, the temperature of the cooled water of the water cooling device may be detected by the temperature detector in real time. During a process of decreasing the temperature, the actual falling time of each temperature point of the detected water temperatures is recorded, and during a process of increasing the temperature, the actual rising time of each temperature point of the detected water temperatures is recorded. For example, the actual falling times of a plurality of the temperature points may be recorded as m0, m1, m2, . . . , respectively, and the actual rising times of a plurality of the temperature points may be recorded as n0, n1, n2, . . . , respectively. It should be understood that when the cooled water in the water drinking apparatus is used by a user, the time required for the increase or decrease of the water temperature will be affected, resulting in a large difference between the actual rising time or the actual falling time and the corresponding time acquired in the test.
In addition, it should be noted that when the temperature is decreased, an actual falling time of a temperature point which is not detected in the water temperature range may be directly set as the falling reference time of the temperature point, and when the temperature is increased, an actual rising time of a temperature point which is not detected in the water temperature range may be directly set as the rising reference time of the temperature point.
At S4, it is determined whether the water drinking apparatus is in a water discharging state according to the rising reference time, the falling reference time, the rising reference adjustment value, and the falling reference adjustment value of each temperature point, and the actual rising time and the actual falling time of each temperature point.
Specifically, after the actual rising time and the actual falling time of each temperature point are acquired, an actual rising time of a temperature point may be compared with a rising reference time and a rising reference adjustment value of this temperature point to acquire a first comparison result, and an actual falling time of a temperature point may be compared with a falling reference time and a falling reference adjustment value of this temperature point to obtain a second comparison result. According to the first comparison result and the second comparison result, it may be determined that whether the water drinking apparatus is in the water discharging state.
In an embodiment of the present disclosure, determining whether the water drinking apparatus is in a water discharging state according to the rising reference time, the falling reference time, the rising reference adjustment value, and the falling reference adjustment value of each temperature point, and the actual rising time and the actual falling time of each temperature point includes:
determining whether an actual falling time of any temperature point is greater than a first preset multiple of a sum of a falling reference time and a falling reference adjustment value of the temperature point;
if yes, determining that the water drinking apparatus is in the water discharging state.
Specifically, the first preset multiple is constant and greater than or equal to 2.
Specifically, when the water drinking apparatus is working, an ith temperature point Ti is taken as an example, if an actual falling time mi of the temperature point Ti is greater than the first preset multiple K0 of the sum of the falling reference time Mi and the falling reference adjustment value Pi of the temperature point Ti, i.e., mi>(Mi+Pi)*K0, it is determined that the water drinking apparatus is in the water discharging state.
In other words, if there is a significant increase in the actual falling time of any temperature point compared to the time tested in the whole machine test, it indicates that there is heat exchange between the water in the water cooling device and external water (for example, water in a water tank of the water drinking apparatus). On this basis, it may be determined that the water drinking apparatus is in the water discharging state.
In an embodiment of the present disclosure, determining whether the water drinking apparatus is in a water discharging state according to the rising reference time, the falling reference time, the rising reference adjustment value, and the falling reference adjustment value of each temperature point, and the actual rising time and the actual falling time of each temperature point further includes:
Specifically, when the water drinking apparatus is working, if there are three consecutive temperature points such as an ith temperature point Ti, an (i+1)th temperature point T(i+1) and the an i+2th temperature point T(i+2) meeting the following conditions: mi >(Mi+Pi), m(i+1) >[M(i+1)+P(i+1)] and m(i+2)>[M(i+2)+P(i+2)], it is determined that the water drinking apparatus is in the water discharging state.
In other words, when compared with the whole machine test, if the actual falling time of each of the three consecutive temperature points is greater than the sum of the falling reference time and the falling reference adjustment value of each of the three consecutive temperature points, it indicates that there is heat exchange between the water in the water cooling device and external water (for example, water in a water tank of the water drinking apparatus). On this basis, it may be determined that the water drinking apparatus is in the water discharging state.
In an embodiment of the present disclosure, determining whether the water drinking apparatus is in a water discharging state according to the rising reference time, the falling reference time, the rising reference adjustment value, and the falling reference adjustment value of each temperature point, and the actual rising time and the actual falling time of each temperature point further includes:
Specifically, the second preset multiple is constant and smaller than 1.
Specifically, when the water drinking apparatus is working, an ith temperature point Ti is taken as an example, if an actual rising time ni of the temperature point Ti is smaller the second preset multiple K1 of the difference between the rising reference time Ni and a rising reference adjustment value Qi of the temperature point Ti, i.e., ni<(Ni−Qi)*K1, it is determined that the water drinking apparatus is in the water discharging state.
In other words, if there is a significant decrease in the actual rising time of any temperature point compared to the time tested in the whole machine test, it indicates that there is heat exchange between the water in the water cooling device and external water (for example, water in a water tank of the water drinking apparatus). On this basis, it may be determined that the water drinking apparatus is in the water discharging state.
In an embodiment of the present disclosure, determining whether the water drinking apparatus is in a water discharging state according to the rising reference time, the falling reference time, the rising reference adjustment value, and the falling reference adjustment value of each temperature point, and the actual rising time and the actual falling time of each temperature point further includes:
Specifically, when the water drinking apparatus is working, if there are three consecutive temperature points such as an ith temperature point Ti, an i+1th temperature point T(i+1) and the an (i+2)th temperature point T(i+2) meeting the following conditions: ni <(Ni−Qi), n(i+1)<[N(i+1)−Q(i+1)] and n(i+2)<[N(i+2)−Q(i+2)], it is determined that the water drinking apparatus is in the water discharging state.
In other words, when compared with the whole machine test, if the actual rising time of each of the three consecutive temperature points is smaller than the difference between the rising reference time and the rising reference adjustment value of the each of the three consecutive temperature points, it indicates that there is heat exchange between the water in the water cooling device and external water (for example, water in a water tank of the water drinking apparatus). On this basis, it may be determined that the water drinking apparatus is in the water discharging state.
In addition, in an embodiment of the present disclosure, it is determined that the water drinking apparatus is in the water discharging state when the water temperature of the cooled water of the water cooling device is in a rising state and is increased by jump.
Specifically, when the water drinking apparatus is working, if the temperature is increased from a certain temperature point to another temperature point by jump, for example, from an ith temperature point to an i+3th temperature point, it indicates that there is heat exchange between the water in the water cooling device and external water (for example, water in a water tank of the water drinking apparatus), resulting in an inconsecutive temperature change. On this basis, it may be determined that the water drinking apparatus is in the water discharging state.
In addition, if it is determined that none of the rising reference time, the falling reference time, the rising reference adjustment value and the falling reference adjustment value, and the actual rising time and the actual falling time detected in real time of each temperature point satisfies the above conditions, it indicates that the water drinking apparatus is not in the water discharging state.

if yes, performing S109; if no, performing S104.
S104: determining whether an actual falling time mi, m(i+1) or m(i+2) of each of three consecutive temperature points is greater than a sum of a falling reference time Mi, M(i+1) or M(i+2) and a falling reference adjustment value Pi, P(i+1) or P(i+2) of the each of the three consecutive temperature points;
if yes, performing S109; if no, performing S105.

S109: determining that the water drinking apparatus is in a water discharging state.
It should be noted that, during the actual working process of the water drinking apparatus, when the water drinking apparatus is not in the water discharging state, M rising and falling periods are cycled continuously. If an absolute value of the difference between the actual rising time and the rising reference time of each temperature point is smaller than the rising reference adjustment value, and an absolute value of the difference between the actual falling time and the falling reference time of each temperature point is smaller than the falling reference adjustment value, an average value of the M actual rising times or M actual falling times of each temperature point is calculated, and further used as an updated rising reference time or falling reference time of the temperature point, in which M may be 3.
In addition, in an embodiment of the present disclosure, when it is determined whether the water drinking apparatus is in the water discharging state, a display device of the water drinking apparatus may be controlled to display to present a state prompt to the user. Alternatively, when it is determined whether the water drinking apparatus is in the water discharging state, the water drinking apparatus is configured to perform a cooling control according to a preset control program.
In conclusion, with the method for detecting water discharge of a water drinking apparatus provided by embodiments of the present disclosure, the water temperature of the cooled water of the water cooling device is detected in real time, and the actual rising time and the actual falling time of each temperature point are acquired according to the water temperature of the cooled water of the water cooling device, it is determined whether the water drinking apparatus is in a water discharging state according to the rising reference time, the falling reference time, the rising reference adjustment value, and the falling reference adjustment value of each temperature point, and the actual rising time and the actual falling time of each temperature point. Therefore, the method may be applied to determine the water discharging state of the water drinking apparatus without solenoid valve, thus decreasing the production cost of the water drinking apparatus and simplifying the structure of the water drinking apparatus.
Specifically, the water cooling device 101 is configured to cool water, and the water of the water drinking apparatus is cooled by the water cooling device 101 and then flows out through the cooled water mechanical faucet. The temperature detector 102 is configured to detect a water temperature of cooled water of the water cooling device and may be disposed inside the water cooling device 101. The control module 103 is coupled to the water cooling device 101 and the temperature detector 102, respectively. Specifically, after the water drinking apparatus is powered on, the control module 103 is configured to control the water cooling device 101 to cool the water down, and the temperature detector 102 is configured to transmit the water temperatures detected in real time to the control module 103, and the control module 103 is configured to store and process the received water temperature data.
The control module 103 is configured to acquire a water temperature range of the cooled water of the water cooling device, and acquire a plurality of temperature points according to the water temperature range and acquire a rising reference time, a falling reference time, a rising reference adjustment value, and a falling reference adjustment value of each temperature point. Specifically, during operation of the water cooling device, the control module 103 is further configured to acquire an actual rising time and an actual falling time of each temperature point according to the water temperature of the cooled water of the water cooling device 101 and determine whether the water drinking apparatus is in a water discharging state according to the rising reference time, the falling reference time, the rising reference adjustment value and the falling reference adjustment value of each temperature point, and the actual rising time and the actual falling time of each temperature point.
Specifically, the water temperature range [Tmin, Tmax] of the cooled water may be determined according to the refrigeration performance of the water cooling device, and after the water temperature range [Tmin, Tmax] is determined, a plurality of temperature points to be recorded can be determined, for example, every temperature point is recorded with an interval of 1° C., and the number of temperature points to be recorded in the water temperature range [Tmin, Tmax] is Tmax-Tmin.
The water drinking apparatus is powered on and a whole machine test is performed. In this case, when the water cooling device 101 starts to work, the temperature detector 102 is configured to detect the temperature of the cooled water of the water cooling device 101, and the control module 103 is configured to record the rising time and the falling time of each temperature point. In other words, when the water temperature is increased, the rising time of each temperature point is recorded by the control module 103, and when the water temperature is decreased, the falling time of each temperature point is recorded by the control module 103. It should be noted that each temperature point has two adjacent temperature points, the rising time of a temperature point refers to the time when the temperature point is increased to a larger temperature point of two adjacent temperature points, and the falling time of a temperature point refers to the time when the temperature point is decreased to a smaller temperature point of the two adjacent temperature points. For example, there are three consecutive temperature points T1, T2 and T3, in which T1<T2<T3, such that the rising time of the temperature point T2 refers to the time when the temperature point T2 is increased to the temperature point T3, and the falling time of the temperature point T2 refers to the time when the temperature point T2 is decreased to the temperature point T1.
Therefore, the whole machine test is performed for N times to record N rising times and N falling times of the temperature points, N is a positive integer. The control module 103 is configured to acquire a rising reference time, a falling reference time, a rising reference adjustment value and a falling reference adjustment value of each temperature point according to the N rising times and the N falling times of the temperature points. For example, according to the cooling test of the whole machine, the control module 103 is configured to determine the following set of values.
When the temperature is decreased, the falling reference times of a plurality of temperature points may be M0, M1, M2, . . . , respectively.
When the temperature is decreased, the falling reference adjustment values of a plurality of temperature points may be P0, P1, P2, . . . , respectively.
When the temperature is increased, the rising reference times of a plurality of temperature points may be N0, N1, N2, . . . , respectively.
When the temperature is increased, the rising reference adjustment values of a plurality of temperature points may be Q0, Q1, Q2, . . . , respectively.
It should be understood that the water drinking apparatus is not in the water discharging state during the whole machine test.
Further, in the case that the water drinking apparatus is powered on and is working, when the water temperature is changed, the temperature of the cooled water of the water cooling device 101 may be detected by the temperature detector 102 in real time. During a process of decreasing the temperature, the control module 103 is configured to record the actual falling time of each temperature point of the detected water temperatures, and during a process of increasing the temperature, the control module 103 is configured to record the actual rising time of each temperature point of the detected water temperatures. For example, the actual falling times of a plurality of the temperature points may be recorded as m0, m1, m2, . . . , respectively, and the actual rising times of a plurality of the temperature points may be recorded as n0, n1, n2, . . . , respectively.
In this case, after the actual rising time and the actual falling time of each temperature point are acquired by the control module 103, an actual rising time of a temperature point may be compared with a rising reference time and a rising reference adjustment value of this temperature point to acquire a first comparison result, and an actual falling time of a temperature point may be compared with a falling reference time and a falling reference adjustment value of this temperature point to obtain a second comparison result. According to the first comparison result and the second comparison result, it may be determined that whether the water drinking apparatus is in the water discharging state.
In an embodiment of the present disclosure, the control module 103 is configured to determine that the water drinking apparatus is in the water discharging state when an actual falling time of any temperature point is greater than a first preset multiple of a sum of a falling reference time and a falling reference adjustment value of the temperature point.
Specifically, when the water drinking apparatus is working, the control module 103 is configured to analyze and process the water temperature data. If an actual falling time mi of an ith temperature point Ti is greater than the first preset multiple KO of the sum of the falling reference time Mi and the falling reference adjustment value Pi of the temperature point Ti, i.e., mi>(Mi+Pi)*K0, it is determined by the control module 103 that the water drinking apparatus is in the water discharging state.
In other words, if there is a significant increase in the actual falling time of any temperature point compared to the time tested in the whole machine test, it indicates that there is heat exchange between the water in the water cooling device 101 and external water (for example, water in a water tank of the water drinking apparatus). On this basis, it may be determined by the control module 103 that the water drinking apparatus is in the water discharging state.
In an embodiment of the present disclosure, the control module 103 is configured to determine that the water drinking apparatus is in the water discharging state when an actual falling time mi, m(i+1) or m(i+2) of each of three consecutive temperature points is greater than a sum of a falling reference time Mi, M(i+1) or M(i+2) and a falling reference adjustment value Pi, P(i+1) or P(i+2) of the each of the three consecutive temperature points.
Specifically, when the water drinking apparatus is working, if there are three consecutive temperature points such as an ith temperature point Ti, an i+1th temperature point T(i+1) and the an i+2th temperature point T(i+2) meeting the following conditions: mi >(Mi+Pi), m(i+1)>[M(i+1)+P(i+1)] and m(i+2)>[M(i+2)+P(i+2)], it is determined by the control module 103 that the water drinking apparatus is in the water discharging state.
In other words, when compared with the whole machine test, if the actual falling time of each of the three consecutive temperature points is greater than the sum of the falling reference time and the falling reference adjustment value of each of the three consecutive temperature points, it indicates that there is heat exchange between the water in the water cooling device 101 and external water (for example, water in a water tank of the water drinking apparatus). On this basis, it may be determined by the control module 103 that the water drinking apparatus is in the water discharging state.
In an embodiment of the present disclosure, the control module 103 is configured to determine that the water drinking apparatus is in the water discharging state when an actual rising time ni of any temperature point is smaller than a second preset multiple K1 of a difference between a rising reference time Ni and a rising reference adjustment value Qi of the temperature point.
Specifically, when the water drinking apparatus is working, the control module 103 is configured to analyze and process the water temperature data. If an actual rising time ni of an ith temperature point Ti is smaller the second preset multiple K1 of the difference between the rising reference time Ni and a rising reference adjustment value Qi of the temperature point Ti, i.e., ni<(Ni−Qi)*K1, it is determined by the control module 103 that the water drinking apparatus is in the water discharging state.
In other words, if there is a significant decrease in the actual rising time of any temperature point compared to the time tested in the whole machine test, it indicates that there is heat exchange between the water in the water cooling device 101 and external water (for example, water in a water tank of the water drinking apparatus). On this basis, it may be determined by the control module 103 that the water drinking apparatus is in the water discharging state.
In an embodiment of the present disclosure, the control module 103 is configured to determine that the water drinking apparatus is in the water discharging state when an actual rising time ni, n(i+1) or n(i+2) of each of three consecutive temperature points is smaller than a difference between a rising reference time Ni, N(i+1) or N(i+2) and a rising reference adjustment value Qi, Q(i+1) or Q(i+2) of the each of the three consecutive temperature points.
Specifically, when the water drinking apparatus is working, the control module 103 is configured to analyze and process the water temperature data. If there are three consecutive temperature points such as an ith temperature point Ti, an i+1th temperature point T(i+1) and the an i+2th temperature point T(i+2) meeting the following conditions: ni<(Ni−Qi), n(i+1)<[N(i+1)−Q(i+1)] and n(i+2)<[N(i+2)−Q(i+2)], it is determined by the control module 103 that the water drinking apparatus is in the water discharging state.
In other words, when compared with the whole machine test, if the actual rising time of each of the three consecutive temperature points is smaller than the difference between the rising reference time and the rising reference adjustment value of the each of the three consecutive temperature points, it indicates that there is heat exchange between the water in the water cooling device 101 and external water (for example, water in a water tank of the water drinking apparatus). On this basis, it may be determined by the control module 103 that the water drinking apparatus is in the water discharging state.
In an embodiment of the present disclosure, the control module 103 is configured to determine that the water drinking apparatus is in the water discharging state when the water temperature of the cooled water of the water cooling device 101 is in a rising state and is increased by jump.
Specifically, when the water drinking apparatus is working, if the control module 103 is configured to acquire that the temperature is increased from a certain temperature point to another temperature point by jump, it indicates that there is heat exchange between the water in the water cooling device 101 and external water (for example, water in a water tank of the water drinking apparatus), resulting in an inconsecutive temperature change. On this basis, it may be determined by the control module 103 that the water drinking apparatus is in the water discharging state.
In conclusion, with the water drinking apparatus provided by embodiments of the present disclosure, the water temperature of the cooled water of the water cooling device is detected in real time by the temperature detector, and the actual rising time and the actual falling time of each temperature point are acquired by the control module according to the water temperature of the cooled water of the water cooling device, it is determined by the control module whether the water drinking apparatus is in a water discharging state according to the rising reference time, the falling reference time, the rising reference adjustment value, and the falling reference adjustment value of each temperature point, and the actual rising time and the actual falling time of each temperature point. Therefore, the water drinking apparatus is able to determine the water discharging state of the water drinking apparatus without solenoid valve, thus decreasing the production cost of the water drinking apparatus and simplifying the structure of the water drinking apparatus.
