Description

Technical Field

[0001] The invention relates to the technical field of water heater outlet water temperature control, in particular to a constant temperature water heater control system. Background Art

[0002] Water heaters are now widely used in home life and some service industries. With the development of water heaters, the heating speed and water storage capacity of electric water heaters have been improved, and smart WIFI home control has also been added to facilitate the comfort of life. They are mainly divided into two categories, one is electric water heaters, and the other is natural gas water heaters. The main difference between these two types of water heaters is the different ways of heating water, but the pipes connected to the water heaters are the same, one hot water outlet pipe and one cold water inlet pipe. When in use, water is introduced through the cold water inlet pipe to heat the water tank, and then connected to the mixing valve through the hot water outlet pipe, and the outlet water temperature is controlled by controlling the rotary mixing valve.

[0003] However, the existing water heaters cannot control the outlet water temperature well. When opening the manually adjustable mixing valve, it is necessary to continuously adjust the temperature by body feeling until the appropriate temperature is reached. Especially during bathing, after closing the mixing valve when applying shampoo and shower gel, it is necessary to adjust the mixing valve again when opening it. That is, the existing water heater outlet water temperature control technology needs to be adjusted according to body feeling and manual operation, resulting in the inability to accurately control the water heater outlet water temperature and the cumbersome operation. Summary of the invention

[0004] The present invention aims to solve one of the technical problems in the prior art to at least a certain extent, by setting the water outlet temperature of the mixing container, and then calculating the relationship function between Mr and the detected temperature, setting the water outlet of the hot water tee based on the temperature function and the preset temperature, and judging whether the real-time temperature is within the temperature range threshold. If the real-time temperature exceeds the temperature range threshold, adjusting the water outlet of the hot water tee and the water outlet of the cold water tee, and updating the temperature function, so as to solve the problem that the existing water heater outlet temperature control technology needs to be adjusted according to body sensation and manual operation, resulting in the inability to accurately control the water outlet temperature of the water heater and the cumbersome operation.

[0005] To achieve the above-mentioned purpose, the present application provides a constant temperature water heater control system, comprising: a temperature setting module, a function calculation module and a temperature adjustment module;

[0008] The temperature adjustment module is used to set the water output of the hot water tee and the water output of the cold water tee based on the temperature function and the preset temperature, obtain the water output temperature of the mixing container at this time, mark it as the real-time temperature, and judge whether the difference between the real-time temperature and the preset temperature is a temperature threshold. If the temperature threshold is exceeded, the water output of the hot water tee and the water output of the cold water tee are adjusted, and the temperature function is updated. If the temperature threshold is not exceeded, the water output of the hot water tee and the water output of the cold water tee are maintained.

[0012] The user sets the preset temperature based on the external buttons and the data displayed on the LED display, and uses the SPI interface communication to send the preset temperature to the control circuit board.

[0013] Furthermore, the function calculation module configures a strategy for acquiring the detected temperature, and the strategy for acquiring the detected temperature includes:

[0014] The outlet water temperature of the mixing container is collected once through the temperature sensor at every time interval T, and K consecutive outlet water temperatures are taken as a group of test temperatures. The average value of this group of test temperatures is calculated and marked as the detection temperature T.

[0015] Furthermore, the function calculation module is configured with a scatter plot acquisition strategy, and the scatter plot acquisition strategy includes:

[0016] Get the water output per unit time of the set water mixing container as Mz;

[0017] The water output per unit time of the hot water tee is marked as Mr;

[0018] The maximum value Mrx of the water output per unit time of the hot water tee is obtained, and the maximum value Mrx is evenly divided into N data. The water output per unit time Mr of the hot water tee is controlled by the hot water regulating valve to start releasing hot water from 0, and then the hot water regulating valve is used to control Mr to increase Mrx / N each time until Mr reaches the maximum value.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1 and Figure 2 As shown, the present application provides a constant temperature water heater control system, including: a temperature setting module, a function calculation module and a temperature adjustment module;

[0038] The set temperature module is used to set the outlet water temperature of the water mixing container, which is marked as the preset temperature;

[0039] The temperature setting module is configured with an APP setting strategy, which includes: the user inputs the preset temperature through the APP, and when the user clicks OK, the temperature setting instruction is sent through the APP, the mainboard receives the temperature setting instruction through WIFI, and the mainboard uses the SPI interface communication to send the temperature setting instruction to the control circuit board; the desired temperature can be set before bathing using the app, and the specific functions of the app include but are not limited to controlling the temperature, starting the water heater and a series of other functions; the VCC and GND in the outgoing are used to ensure a stable output voltage, where VCC and GND are the power supply and ground wire respectively; the mainboard and the control circuit board use FPC flexible printed circuit boards;

[0040] The temperature setting module is equipped with a button setting strategy, which includes: the user sets the preset temperature based on the data displayed by the external button and the LED display screen, and uses the SPI interface communication to send the preset temperature to the control circuit board. The temperature can be adjusted according to the button during bathing, adding an adjustable option and providing convenience; specifically, there are 8-way LED digital tube display GPIO and 3-way button constant temperature control GPIO, which are used for water outlet constant temperature adjustment, constant temperature display and fault display, where GPIO is the abbreviation of General Purpose Input / Output, which stands for input and output;

[0041] In actual applications, the preset temperature is set according to the perceived comfort level. For example, if the preset temperature is 40°C, the user enters the preset temperature of 40°C through the APP. When clicking OK, the temperature setting instruction is sent through the APP, and the mainboard receives the temperature setting instruction through WIFI. The mainboard uses the SPI interface communication to send the temperature setting instruction to the control circuit board; when the LED display screen is adjusted to 40°C based on the external button, click OK, and use the SPI interface communication to send 40°C to the control circuit board.

[0042] The function calculation module is used to obtain the water output of the hot water tee and the water output temperature of the mixing container when the water output of the mixing container is unchanged, which are marked as Mr and the detection temperature respectively. Based on Mr and the detection temperature, the relationship function between Mr and the detection temperature is calculated, which is marked as the temperature function;

[0043] In practical applications, the cold water tee is connected with the internal cold water inlet, the external cold water inlet and the cold water regulating valve, the hot water tee is connected with the internal hot water inlet, the external hot water inlet and the hot water regulating valve, the cold water regulating valve and the hot water regulating valve are simultaneously connected with a 50cm bellows, and the 50cm bellows is connected with a 100ml water mixing container; the 50cm bellows and the 100ml water mixing container fully mix the cold water and the hot water;

[0044] The function calculation module configures the acquisition detection temperature strategy, which includes: collecting the outlet water temperature of the mixing container through the temperature sensor once every T time interval, taking K consecutive outlet water temperatures as a group of test temperatures, calculating the average of this group of test temperatures, and marking this group of test temperature average as the detection temperature T; here, because the water is always flowing, the temperature obtained each time has some deviation, so the average of a continuous group of temperatures is taken as the current temperature to make the data more accurate. Because as the current temperature, T is generally set to be very small, such as T = 0.005s;

[0045] In practical applications, the outlet water temperature of the mixing container is collected by the temperature sensor every 0.005s, and 100 consecutive outlet water temperatures are taken as a group of test temperatures, such as 38.2, 38.3, ..., 38.2, etc., in degrees Celsius. The average value of this group of temperature data is 38.2 degrees Celsius, so T = 38.2 degrees Celsius at this time;

[0046] The function calculation module is configured with a scatter plot acquisition strategy, which includes: obtaining the water output per unit time of the set mixing container as Mz; when adjusting the water temperature, the total water output is set, so the total water output needs to be kept as a fixed value, and only the water output of hot water and cold water needs to be adjusted, so Mz is a fixed value; the unit time here is seconds;

[0047] The water output per unit time of the hot water tee is marked as Mr;

[0048] The maximum value Mrx of the water output per unit time of the hot water tee is obtained, and the maximum value Mrx is evenly divided into N data. The water output per unit time Mr of the hot water tee is controlled by the hot water regulating valve to start releasing hot water from 0, and then the hot water regulating valve is used to control Mr to increase Mrx / N each time until Mr reaches the maximum value, and the output Ml of the cold water tee under different Mr is calculated as: Ml=Mz-Mr, and then the cold water regulating valve is used to control the cold water tee to release cold water with the water output Ml, and the size of the detection temperature T under all different combinations of Mr and Ml is obtained; here, in order to obtain the water outlet temperature of the mixed water container under different hot water tee water outputs, it is convenient to obtain the relationship between hot water and temperature later, in order to keep the total water output unchanged, the water output of the hot water tee and the set total water output are obtained, and the water output of the cold water tee can be known;

[0049] With Mr as the X-axis and the detected temperature T as the Y-axis, a plane rectangular coordinate system is established, marked as the temperature coordinate system;

[0050] Plot each set of Mr and detection temperature T data into the temperature coordinate system to obtain a temperature scatter plot;

[0051] The function calculation module is configured with a temperature function acquisition strategy, which includes: based on a preset temperature function: T = a*Mr+b, linearly fitting the temperature scatter plot, obtaining the values ​​of a and b, and obtaining the temperature function;

[0052] For practical applications, please refer to Figure 3 As shown, the water output per second of the set mixing container is obtained as Mz=1.6L, the maximum value of the water output per second of the hot water tee is obtained as Mrx=1.6L, and the maximum value of 1.6L is evenly divided into 8 data; the water output per unit time Mr of the hot water tee is controlled by the hot water regulating valve to release hot water from 0, and then the hot water regulating valve is used to control Mr to increase by 0.2 each time until Mr reaches the maximum value, for example, 0.2L, 0.4L, ..., 1.6L, and the output Ml of the cold water tee under different Mr is calculated as: Ml=Mz-Mr, for example, when Mr=0.2, Ml=Mz-Mr=1.6 -0.2=1.4L, and then the cold water regulating valve is used to control the release of cold water with a water output of 1.4L from the cold water tee, and the size of the detection temperature T under all different combinations of Mr and Ml is obtained. For example, when Mz=1.6L, Mr=0.2L and Ml=1.4L, the temperature T is 11.24℃, and each group of Mr and detection temperature T data is plotted into the temperature coordinate system to obtain a temperature scatter plot. Based on the preset temperature function: T=a*Mr+b, a linear fit is performed on the temperature scatter plot to obtain the values ​​of a=43.56 and b=3.78, and the temperature function is T=43.56*Mr+3.78.

[0053] The temperature adjustment module is used to set the water output of the hot water tee and the water output of the cold water tee based on the temperature function and the preset temperature, obtain the water output temperature of the mixing container at this time, mark it as the real-time temperature, and judge whether the difference between the real-time temperature and the preset temperature is the temperature threshold. If it exceeds the temperature threshold, adjust the water output of the hot water tee and the water output of the cold water tee, update the temperature function, and if it does not exceed the temperature threshold, maintain the water output of the hot water tee and the water output of the cold water tee;

[0054] The temperature adjustment module is configured with a water output control strategy, which includes: obtaining a preset temperature, based on the preset temperature and the temperature function, obtaining the water output Mr of the hot water tee per unit time, marked as Mrs, and calculating the water output Mls of the cold water tee per unit time under Mrs: Mls = Mz-Mrs;

[0055] Then, the hot water regulating valve and the cold water regulating valve are controlled so that the water output per unit time of the hot water tee is Mrs and the water output per unit time of the cold water tee is Mls;

[0056] In practical applications, when the preset temperature is 40°C, according to the temperature function T=43.56*Mr+3.78, Mr=0.83 is obtained, and the result is rounded to two decimal places. Let Mrs=0.83L, and according to Mz=1.6L, the water output Mls of the cold water tee per unit time under Mrs is calculated as: Mls=Mz-Mrs=1.6-0.83=0.77L, and then the hot water regulating valve and the cold water regulating valve are controlled to make the water output per second of the hot water tee 0.83L and the water output per second of the cold water tee 0.77L;

[0057] The temperature adjustment module is configured with an adjustment temperature and function strategy, and the adjustment temperature and function strategy include: obtaining the detected temperature of the water mixing container at this time, marking it as the real-time temperature Tss;

[0058] Label the preset temperature as Tys;

[0059] The difference between the real-time temperature and the preset temperature is calculated as: Tcz = Tss - Tys; where Tcz is the difference between the real-time temperature and the preset temperature;

[0060] Determine whether |Tcz| exceeds the temperature threshold. If it exceeds the temperature threshold and Tcz is a positive number, reduce the water output per unit time of the hot water tee by Tcz / a, and increase the water output per unit time of the cold water tee by Tcz / a. If it exceeds the temperature threshold and Tcz is a negative number, increase the water output per unit time of the hot water tee by |Tcz| / a, and reduce the water output per unit time of the cold water tee by |Tcz| / a. Update the temperature function at the same time until Tcz is less than the temperature threshold. Tcz / a can be obtained by changing so many temperatures according to the temperature function formula, and the change in the water output of the hot water tee can be roughly obtained. The cold water temperature will change in different seasons. Update the temperature function to make the subsequent data more accurate. The temperature threshold is set according to the temperature change that people can feel, such as 0.5℃.

[0061] In practical applications, the real-time temperature Tss=41°C and the preset temperature Tys=40°C are obtained, and the difference between the real-time temperature and the preset temperature is calculated as: Tcz=Tss-Tys=1°C; wherein Tcz is the difference between the real-time temperature and the preset temperature, and it is determined whether |Tcz|=1°C exceeds the temperature threshold of 0.5°C. If 1°C exceeds 0.5°C and Tcz=1°C is a positive number, the water output per second of the hot water tee is reduced by Tcz / a=0.02L, and the result is retained to two decimal places. At the same time, the water output per second of the cold water tee is increased by 0.02L, and the above operation is repeated until |Tcz| is less than the temperature threshold, and the temperature function is updated at the same time.
