[0054] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0055] Example 1

[0056] like Figure 1 As shown, the water outlet temperature control method of the water purifier of embodiment 1 of the present invention comprises the following steps:

[0057] S1, obtaining water usage information set by the user and obtaining internal pipeline information of the water purifier;

[0058] S2, according to the water usage information set by the user and the internal pipeline information of the water purifier, control the heating program and the water outlet program of the water purifier. In this method, by obtaining the internal pipeline information of the water purifier, considering the volume of water in the internal pipeline and the temperature of water in the internal pipeline, the influence of water in the internal pipeline is taken into account during water outlet and heating, thereby better controlling the outlet water temperature, so that the user can obtain the water outlet with precise temperature control.

[0059] The water use information set by the user includes the water output V3 and the water output temperature T3;

[0060] The internal pipeline information of the water purifier includes the volume of the internal pipeline of the water purifier and the temperature of the water in the internal pipeline of the water purifier.

[0061] The volume of the internal pipe of the water purifier includes a first pipe volume V1 and a second pipe volume V2. The first pipe is a pipe of the internal heating body of the water purifier, and the second pipe is a pipe between the internal heating body of the water purifier and the water outlet of the water purifier.

[0062] The temperature of the water in the internal pipe includes a first temperature T1 and a second temperature T2. The first temperature is the temperature of the water entering the heating body, and the second temperature is the temperature of the water in the first pipe and the second pipe. Usually, the first temperature T1 is obtained by a first temperature sensor, which is arranged at the water inlet of the heating body, and the second temperature T2 is obtained by a second temperature sensor, which is arranged on the pipe between the heating body and the water outlet. The second temperature is the temperature of the water in the internal pipe of the water purifier. The internal pipe of the water purifier includes the first pipe in the heating body and the second pipe between the heating body and the water outlet of the water purifier. The first temperature is the temperature of the water entering the internal pipe of the water inlet machine. When the water purifier is installed in the user's home, the length of the water pipe may be cut or increased, which will cause V2 to change. The installer needs to test the V2 value during installation. The water output V3 should be a plurality of quantitative gears, and the minimum gear value V of the water output needs to be quantitative. 3min ≥A×(V1+V2), A is generally 1.5, and V3 is generally an integer multiple of 50ml.

[0063] The step S2 controls the heating program and the water outlet program of the water purifier according to the water outlet information set by the user and the internal pipeline information of the water purifier. Specifically, according to the water outlet information set by the user and the internal pipeline information of the water purifier, it is determined whether the heating body of the water purifier is preheated, the preheating time t, and the actual heating temperature T4, and the heating body of the water purifier is controlled to operate under the corresponding parameters.

[0064] Because there are usually pipes inside the water purifier, a small amount of residual water from the previous heating will be stored in the heating body, which is close to the water outlet of the water purifier and inside the heating body. If the heating temperature of the heating body is only controlled to set the water outlet temperature to T3, and the volume of water inside the pipe is ignored, when the user sets the water outlet, the water flowing out usually cannot reach the water outlet temperature required by the user. If the cold water in the front is released first and then the hot water is connected, the cold water in the front will also be wasted. Therefore, the water temperature can be close to the set water outlet temperature only through the mixed water calculation and preheating and heating control.

[0065] According to the water output information set by the user and the internal pipeline information of the water purifier, it is determined whether the heating body of the water purifier is preheated, the preheating time t, and the actual heating temperature T4, and the heating body of the water purifier is controlled to operate under the corresponding parameters, specifically, as follows: Figure 2 As shown,

[0066] S21, if the water outlet temperature T3 set by the user is less than or equal to the second temperature T2, the actual heating temperature T4 of the water purifier is first obtained by the following formula (1);

[0067]

[0068] At this time, because the set water outlet temperature T3 is lower than the temperature of the internal pipe of the water purifier, it means that the last heating time of the water purifier is not far away, and the temperature of the internal pipe of the water purifier is still slightly higher. The water purifier does not need to be preheated when it is heated again. The actual heating temperature T4 of the water purifier at this time is obtained by the water mixing formula (V1+V2)×(T3-T2)=(V3-V1-V2)×(T4-T3).

[0069] S22, if the actual heating temperature T4 calculated at this time is ≤ the second temperature T2, that is, the actual heating temperature is lower than the temperature of the internal pipe, and the water outlet temperature set by the user is even lower, then the heating body of the water purifier does not need to be heated or preheated, and the water purifier directly outputs the water output V3; at this time, because the hot water volume is high and the hot water temperature is also high, cold water can be directly output to mix with the hot water in the pipe to achieve a water outlet temperature that is closest to the water outlet temperature set by the user.

[0070] S23, if the actual heating temperature T4>the second temperature T2, the heating body of the water purifier does not need to be preheated, and the heating body of the water purifier is controlled to operate at the actual heating temperature T4, and the water purifier outputs the water output V3.

[0071] S24, if the outlet water temperature T3> the second temperature T2, the actual heating temperature T4 of the water purifier is obtained by the following formula (2);

[0072]

[0073] Because at this time, it means that the pipeline has cooled down and the temperature of the water in the pipeline is also relatively low. If the heating temperature is directly set and then water is discharged, the water temperature in the heating body cannot be increased all at once, so the heating body needs to be preheated before water is discharged. The preheating of the heating body means preheating the water in the first pipeline of the heating body before discharging the water. Therefore, due to the need for preheating, the actual heating temperature T4 is also different from the above-mentioned situation where no preheating is required.

[0074] After the heating body is controlled to be preheated at the maximum power of the water purifier, the water purifier then outputs the water output V3; according to the power formula, power (kW) = temperature difference (K) × flow rate (kg / min) × 4.2 / 60, the preheating time of the heating body of the water purifier is,

[0075]

[0076] The unit is seconds, where P is the maximum power of the water purifier's heating element.

[0077] The water outlet temperature thus obtained can be closest to T3, and the user can obtain the water outlet with the precise water temperature closest to the set water outlet temperature.

[0078] The water outlet temperature control method of the water purifier of this embodiment can take into account the volume and water temperature of the internal pipes of the water purifier, and then accurately control the water outlet temperature through water mixing control, so that the user can obtain water with the most accurate water temperature.

[0080] like Figure 3 As shown, a water outlet temperature control device for a water purifier provided in Embodiment 2 of the present invention comprises:

[0081] The first acquisition module 1 is used to acquire the water consumption information of the user; the water consumption information set by the user includes the water output V3 and the water output temperature T3.

[0082] The second acquisition module 2 is used to acquire the internal pipeline information of the water purifier; the internal pipeline information of the water purifier includes the volume of the internal pipeline of the water purifier and the temperature of the water in the internal pipeline of the water purifier. The volume of the internal pipeline of the water purifier includes a first pipeline volume V1 and a second pipeline volume V2, the first pipeline is the pipeline of the internal heating body of the water purifier, and the second pipeline is the pipeline between the internal heating body of the water purifier and the water outlet of the water purifier;

[0083] The temperature of the water in the internal pipe includes a first temperature T1 and a second temperature T2. The first temperature T1 is the temperature of the water entering the heating body, and the second temperature T2 is the temperature of the water in the first pipe and the second pipe.

[0084] The control module 3 is used to control the heating program and the water output program of the water purifier according to the water usage information set by the user and the internal pipeline information of the water purifier.

[0085] The first acquisition module includes:

[0086] The outlet water temperature acquisition module 11 is used to acquire the outlet water temperature T3 set by the user.

[0087] The water output acquisition module 12 is used to obtain the water output V3 set by the user.

[0088] The second acquisition module includes:

[0089] A first volume acquisition module 21, used to acquire a first pipeline volume V1;

[0090] A second volume acquisition module 22, used to acquire a second pipeline volume V2;

[0091] The first temperature acquisition module 23 is used to acquire the first temperature T1; for example, it can be a first temperature sensor disposed at the water inlet side of the heating body.

[0092] The second temperature acquisition module 24 is used to obtain the second temperature T2; for example, it can be a second temperature sensor arranged on the pipe between the heating body and the water outlet of the water purifier. The second temperature sensor can also be arranged in the heating body. It is assumed that the temperature in the heating body and the temperature in the pipe between the heating body and the water outlet are the same.

[0093] The first pipe is a pipe of the internal heating body of the water purifier, and the second pipe is a pipe between the internal heating body of the water purifier and the water outlet of the water purifier; the first temperature T1 is the temperature of water entering the heating body, and the second temperature T2 is the temperature of water in the first pipe and the second pipe.

[0094] The control module 3 includes:

[0095] A heating temperature determination module 31 is used to determine an actual heating temperature T4;

[0096] A preheating determination module 32 is used to determine whether preheating is required;

[0097] A preheating time determination module 33, used to determine the preheating time t when preheating is required;

[0098] A heating control module 34, used to control whether the heating body is heated, and to control the heating of the heating body according to the actual heating temperature determined by the heating temperature determination module;

[0099] The water outlet control module 35 is used to control the water outlet of the water purifier.

[0100] If the water outlet temperature T3 set by the user is less than or equal to the second temperature T2, the heating temperature determination module 31 first obtains the actual heating temperature T4 of the water purifier;

[0101]

[0102] If the actual heating temperature T4 calculated at this time is ≤ the second temperature T2, that is, the actual heating temperature T4 is lower than the temperature of the internal pipe, and the water outlet temperature set by the user is lower, the preheating judgment module 32 determines that preheating is not required, and the preheating time determination module 33 does not need to calculate the preheating time t. The heating control module 34 controls the heating body not to heat, and the water outlet control module 35 controls the water purifier to directly output the water outlet V3.

[0103] If the actual heating temperature T4>the second temperature T2, the preheating judgment module 32 determines that the heating body of the water purifier does not need to be preheated, and the preheating time determination module 33 does not need to calculate the preheating time t. The heating control module 34 controls the heating body of the water purifier to operate at the actual heating temperature T4, and the water output control module 35 controls the water purifier to output the water output V3.

[0104] If the outlet water temperature T3>the second temperature T2, the heating temperature determination module 31 obtains the actual heating temperature T4 of the water purifier through the following formula;

[0105]

[0106] The preheating judgment module 32 confirms that preheating is required, and then the heating control module 34 controls the heating body of the water purifier to preheat at the maximum power P for a time t, and the water output control module 35 controls the water purifier to output the water output V3. Among them, the preheating time determination module 33 uses the power formula, power (kW) = temperature difference (K) × flow rate (kg / min) × 4.2 / 60. The preheating time of the heating body of the water purifier is,

[0107]

[0108] The unit is seconds, where P is the maximum power of the water purifier's heating element.
