Fig. 1 is the method schematic diagram for the embodiment for water heater provided by the invention remaining heating time determining method.

As shown in Figure 1, according to one embodiment of present invention, the method for the determining water heater remaining heating time is at least Including step S110 and step S120.

Step S110 detects multiple positions that water tank bottom height described in distance is different in the water tank of the water heater respectively Locate current temperature value.

Specifically, multiple temperature-detecting devices, the temperature-detecting device example can be correspondingly arranged in the multiple position It such as can be temperature sensor.It is the multiple by being correspondingly arranged multiple temperature-detecting devices detections at the multiple position respectively Current temperature value at position.

Preferably, the spacing between the every two adjacent position in the multiple position in the short transverse of the water tank Be equal, and in the multiple position water tank bottom described in the nearest positional distance of water tank bottom described in distance distance, and Distance away from tank top described in the nearest positional distance of the tank top is equal to the half of the spacing.That is, will The water tank is divided into multiple equal portions along short transverse, and the multiple position is located at the multiple equal portions being divided into Middle position.

For example, as shown in Fig. 2, the height of water tank 1 is h, the height in water tank 1 apart from water tank bottom be h1, h2 ..., hn N position at setting be respectively arranged with temperature-detecting device, along the sequence of tank height direction from high to low be h1, h2 ..., Hn, wherein h1-h2=h2-h3=...=2hn=2 (h-h1).

Step S120 determines the current residue of the water heater according to temperature value current at the multiple position of detection Heating time.

Fig. 3 is that temperature value current at the multiple position according to an embodiment of the present invention according to detection determines the heat A kind of flow diagram of specific embodiment of hydrophone current remaining heating time.As shown in figure 3, in a kind of specific implementation In mode, step S120 includes step S121 and step S122.

Step S121, when obtaining temperature value and the remaining heating at pre-set ambient temperature value and the multiple position Between corresponding relationship.

Wherein it is possible to the temperature value being configured at the ambient temperature value and the multiple position in the following manner with The corresponding relationship of remaining heating time:

A) after the water heater is begun to warm up, temperature value at real-time detection ambient temperature value and the multiple position, And record the temperature value at the ambient temperature value that detects and the multiple position, and the detection ambient temperature value and The first system time of temperature value at the multiple position.

For example, can be detected every the first predetermined time (for example, 1s) after the water heater is begun to warm up and record ring Temperature value at border temperature value and the multiple position, and record the first system time t when detection every time_i。

Preferably, after the temperature value at detection ambient temperature value every time and the multiple position, when this is detected The ambient temperature value and the multiple position at temperature value and the ambient temperature value that detects of last time and described more Temperature value at a position is compared, when at least one temperature value changes, just the ambient temperature value that detects of record and Temperature value at the multiple position, and detect the first system of the temperature value at the ambient temperature value and the multiple position It unites the time.That is, at least one in temperature value at the ambient temperature value that detect and the multiple position changes, just into The record of trip temperature value and system time.

Specifically, the ambient temperature value of detection, the temperature value at the multiple position can be recorded according to table 1, and Detect the first system time of the temperature value at the ambient temperature value and the multiple position:

Table 1

B) after the completion of the water heater heats, according to the detection recorded every time the ambient temperature value and the multiple position Set the temperature value at place the first system time and heating complete when the second system time, calculate separately record every time it is described Temperature value corresponding remaining heating time at ambient temperature value and the multiple position.

Specifically, the corresponding residue of temperature value at the ambient temperature value recorded every time and the multiple position adds The hot time is equal to the time difference of the second system time and the first system time recorded every time when the heating is completed, That is, the temperature at multiple positions of the ambient temperature value and water tank that environment temperature is detection is the temperature value of detection When, until practical taken time is completed in water heater heating.For example, set heating complete when the second system time as t_k, any primary The first system time for detecting the temperature value at the ambient temperature value and the multiple position of record is t_i, then corresponding surplus Remaining heating time is t_k-t_i。

C) corresponding according to the temperature value at the ambient temperature value recorded every time and the multiple position being calculated Remaining heating time, it is corresponding with remaining heating time to establish temperature value at the ambient temperature value and the multiple position Relationship.

In a specific embodiment, the corresponding relationship can be at the ambient temperature value and the multiple position Temperature value and the mapping table of remaining heating time, for example, can take time to remain wherein heating is practical with reference table 2 Remaining heating time.

Table 2

In the heating process of each water heater, constantly by above-mentioned mode, establish different apart from water tank bottom height Multiple positions at temperature value, ambient temperature value and remaining heating time corresponding relationship, so as to reach continuous self-study The purpose of habit increases the accuracy that water heater remaining heating time is determined according to the corresponding relationship.

Step S122, searched in the corresponding relationship with it is current at current ambient temperature value and the multiple position Temperature value matching degree highest remaining heating time, to be determined as the water heater current remaining heating time.

It specifically, can be in the temperature value and pair of remaining heating time at the ambient temperature value and the multiple position In should being related to, search and the immediate one group of ring of temperature value current at the current ambient temperature value and the multiple position The parameter combination of temperature value at border temperature value and the multiple position, corresponding residue heating time are described current Current temperature value matching degree highest remaining heating time, is determined as the hot water at ambient temperature value and the multiple position Device current remaining heating time.

Fig. 4 is that temperature value current at the multiple position according to an embodiment of the present invention according to detection determines the heat The flow diagram of another specific embodiment of hydrophone current remaining heating time.As shown in figure 4, another specific In embodiment, step S120 includes step S123, step S124 and step S125.

Step S123, according to temperature value current at the multiple position of detection, calculating adds the water in the water tank Heat to target temperature value the first demand heat.

Specifically, it can be calculated according to temperature value current at the multiple position of thermal transport formula and detection by institute State the first demand heat that the water in water tank is heated to target temperature value.

Thermal transport formula are as follows:

Q=Δ Tcm (1)

Wherein, Q is heat, unit J；Δ T is the temperature difference, and unit is DEG C；C is specific heat capacity, and unit is J/ (kgK)；M is Quality, unit kg；

Preferably, between the every two adjacent position in the multiple position in the short transverse of the water tank Away from being equal, and in the multiple position water tank bottom described in the nearest positional distance of water tank bottom described in distance distance, with And the distance away from tank top described in the nearest positional distance of the tank top be equal to the spacing half when, be equivalent to institute It states water tank and is divided into multiple equal portions in equal size along short transverse, the multiple position is located at the multiple equal portions being divided into Middle position.Also it is equivalent to, the temperature-detecting device being arranged at each position in the multiple position detects water respectively The temperature value of the corresponding equal portions of case.

For example, as shown in Fig. 2, in water tank 1 water gross mass m, height apart from water tank bottom be h1, h2 ..., the n of hn A position, wherein h1-h2=h2-h3=...=hn；Temperature value in the multiple position at each position is T_i；It then can root It obtains the water in water tank being heated to target temperature T according to formula (2)_sThe first required demand heat Q_Demand:

Due to,Therefore, available:

Q_Demand=(nT_s-T₁-T₂-…-T_n)·c·m_i(3’)

Also that is,

Alternatively, the water in water tank is heated to target temperature T_sRequired first demand heat Q_DemandEqual to target temperature Value T_sWith the temperature gap of the average value of the temperature value of the multiple positionThe quality m of Water in Water Tanks and the ratio of water The product of thermal capacitance c, wherein Therefore,According to thermal transport formula also available above-mentioned formula (3).

Step S124 obtains the corresponding relationship of pre-set demand heat and remaining heating time.

Specifically, the corresponding relationship of the demand heat and heating time, can be arranged in the following manner:

A the temperature value) after the water heater is begun to warm up, at the multiple position of real-time detection.

For example, the temperature value at the multiple position can be detected every the second predetermined time (for example, 1s).

B it) according to the temperature value at the multiple position of detection, calculates and the water in the water tank is heated to target temperature Second demand heat of value.

Wherein, it according to the temperature value at the multiple position of detection, calculates and the water in the water tank is heated to target The specific implementation of second demand heat of temperature value, in abovementioned steps S123 according to working as at the multiple position of detection Preceding temperature value calculates the specific implementation base that the water in the water tank is heated to the first demand heat of target temperature value This is similar, i.e., according to temperature value current at the multiple position of thermal transport formula and detection, calculating will be in the water tank Water be heated to the second demand heat of target temperature value, details are not described herein again.

C) record detects the third system time and the second demand heat of the temperature value at the multiple position.

Preferably, the temperature value at the multiple position every time according to detection, calculating add the water in the water tank After heat to the second demand heat of target temperature value, when the second demand heat that this is calculated is obtained with last computation To the heat difference of the second demand heat reach preset threshold when, just record this and detect the temperature at the multiple position The third system time t of angle value_iThe the second demand heat Q being calculated with this_i。

For example, the third system time and the second demand heat can be recorded by following table 3,

Third system time	Second demand heat
		t₀	Q₀
t₁	Q₁
		…	…
t_k-1	Q_k-1
		t_k	0

Table 3

D) after the completion of the water heater heats, added according to the third system time recorded every time and the water heater The 4th system time when heat is completed determines the second demand heat corresponding practical heating time recorded every time.

Specifically, the second demand heat corresponding practical heating time being calculated every time is equal to the water heater The time difference of the 4th system time and the third system time recorded every time when heating is completed.It is completed for example, setting heating When the 4th system time be t_k, what is arbitrarily once recorded detects the temperature value at the ambient temperature value and the multiple position Third system time be t_i, then corresponding practical heating time is t_k-t_i。

Preferably due to which environment temperature has larger impact to the rate of heat addition, environment temperature is divided into multiple temperature ranges, According to the operating condition of water heater at different ambient temperatures, the need in the multiple temperature range under each temperature range are established Seek heat-residue heating time corresponding relationship curve graph.For example, environment temperature is divided into for a temperature range with 5 DEG C Multiple temperature ranges.Specifically, available that the average ring that the water heater heating is completed is begun heat to from the water heater Border temperature value is established demand heat and is remained according to the second demand heat corresponding practical heating time recorded every time It is locating at least one preset temperature range according to the average ambient temperature value when corresponding relationship of remaining heating time First temperature range establishes the corresponding relationship of the corresponding demand heat of first temperature range and remaining heating time.

Based on above embodiment, it is preferable that corresponding with remaining heating time obtaining pre-set demand heat When relationship, current ambient temperature value second temperature section locating at least one preset temperature range is first determined；Again Obtain the corresponding relationship of the corresponding demand heat in the second temperature section and remaining heating time.

In the heating process of each water heater, demand heat and remaining heating time are constantly established by above-mentioned mode Corresponding relationship increase so as to achieve the purpose that continuous self study and determine that water heater residue adds according to the corresponding relationship The accuracy of hot time.
