Detailed Description
An intelligent temperature control system of a water heater comprises a key module 1 for controlling the start and the close of an intelligent temperature working mode, a CPU control module 2 connected with the key module 1, a detection module 3 for detecting the temperature of inlet water and a main control substrate 4 connected with the detection module 3. The main control substrate 4 is in bidirectional communication connection with the CPU control module 2, the main control substrate 4 can transmit the water inlet temperature value detected by the detection module 3 to the CPU control module 2, the CPU control module 2 can automatically calculate the set temperature value according to the water inlet temperature value and feed back the set temperature value to the main control substrate 4, and the main control substrate 4 controls the combustion intensity of the burner according to the set temperature value.
The intelligent temperature control system of the water heater also comprises a digital display module 5 for displaying the set temperature value, wherein the digital display module 5 is connected with the CPU control module 2.
The key module 1 is provided with a power key 11, an intelligent temperature key 12 for starting and closing an intelligent temperature working mode, and an add key 13 and a subtract key 14 for manually controlling a set temperature. In the case that the smart hotkey 12 is operated, the plus key 13 and the minus key 14 do not work. Therefore, the intelligent temperature control system of the water heater has two operation modes: the intelligent temperature working mode and the manual temperature control mode can be selected by a user. The intelligent temperature control system of the water heater is started to work only when a user selects an intelligent temperature working mode.
The intelligent temperature control system of the water heater is provided with a plurality of intelligent temperature sections, and in a preferred embodiment, the intelligent temperature sections are divided into 5 sections. After the intelligent temperature working mode is started, the CPU control module 2 determines which number of intelligent temperature segments belongs to according to the inlet water temperature value detected by the detection module 3 (intelligent temperature 1 segment.
The change process of the set temperature value is as follows: in the temperature rising process, the temperature is reduced from the existing set temperature value to the set temperature value corresponding to the higher stage number; in the cooling process, the temperature is increased from the existing set temperature value to the set temperature value corresponding to the lower section number.
And the digital display module 5 displays the calculated set temperature value.
The set temperature values are set to 5 segments with equal intervals.
And the inlet temperature values corresponding to the two adjacent set temperature values are arranged in an overlapping manner. The arrangement mode of overlapping 1 ℃ is adopted, and the purpose is to prevent the automatic setting temperature from fluctuating back and forth.
The software work flow of the CPU control module 2 for automatically calculating the set temperature value according to the water inlet temperature value is as follows: after the intelligent temperature working mode is started, the CPU control module 2 judges which intelligent temperature section number belongs to according to the water inlet temperature value; the CPU control module 2 adjusts the number of the segments of the set temperature value up and down according to the change condition of the temperature value of the inlet water, and the digital display module 5 displays the corresponding set temperature value according to the number of the segments. Because the temperature value of entrying is the slow change, consequently, under the continuous intelligent warm mode of operation that opens, CPU control module 2 is according to the change situation of temperature value of entrying, and the number of segments of adjustment setting temperature value is gone up/down in order, promptly, CPU control module 2 control temperature value falls into two adjacent segments, and promptly again, the change process of setting temperature value is: in the temperature rising process, the temperature is reduced by two degrees from the existing set temperature value to the set temperature value corresponding to the next higher stage number; in the cooling process, the temperature is adjusted to be higher by two degrees from the existing set temperature value to the set temperature value corresponding to the next lower stage number. With particular reference to fig. 2 and 3.
For example, the following steps are carried out: when the existing set temperature value is 44 ℃ of the second section, even if the inlet temperature value is heated to 16.5 ℃, because the 16.5 ℃ is within the overlapping temperature range (16 ℃ -17 ℃) of the second section and the third section, the CPU control module 2 does not immediately adjust the set temperature to the set temperature value 42 ℃ corresponding to the third section, but adjusts the inlet temperature value to the set temperature value 42 ℃ corresponding to the third section only when the inlet temperature value is continuously heated to 17 ℃ (inclusive). Similarly, when the existing set temperature value is 42 ℃ of the third section, even if the inlet temperature value is reduced to 16.5 ℃, because the 16.5 ℃ is within the overlapping temperature range (16 ℃ -17 ℃) of the second section and the third section, the CPU control module 2 does not immediately adjust the set temperature to 44 ℃ corresponding to the second section, but adjusts the set temperature to 44 ℃ corresponding to the second section only when the inlet temperature value is continuously reduced to below 16 ℃ (inclusive). In summary, fluctuations of the automatically set temperature back and forth between two adjacent segments are avoided.
The set temperature value of the intelligent temperature control system of the water heater is automatically changed according to the temperature value of the inlet water, and in the temperature rising process, the system is adjusted to be lower from the existing set temperature value to the set temperature value corresponding to the higher section number; in the cooling process, the system is increased from the existing set temperature value to the set temperature value corresponding to the lower segment number, so that the intelligent temperature control system of the water heater can automatically adjust the set temperature according to the water inlet temperature, the set temperature is prevented from being too high or too low, and the use comfort of the water heater is improved.
