The following explanation takes the application of the water heater control method to a water heater as an example.
Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a water heater control method according to an embodiment of the present disclosure.
As shown in fig. 1, the water heater control method includes steps S101 to S104.
And S101, after the water outlet valve is detected to be opened, acquiring the angle information of the water outlet valve deviated to the cold water inlet or the hot water inlet.
The water heater comprises an outlet valve and a shower head, an outlet pipe is connected between the outlet valve and the shower head, and the outlet valve comprises a cold water inlet and a hot water inlet. The user can control the gondola water faucet through the switch of manual regulation and control outlet valve and go out water or stop out water. In addition, the user can regulate and control the outlet water temperature of the shower head by manually regulating and controlling the angle information of the deviation of the outlet valve to the cold water inlet or the hot water inlet.
In one embodiment, the outlet valve is provided with a gate control switch, and the gate control switch comprises a normally-open gate control switch and a normally-closed gate control switch, and is used for detecting whether the outlet valve is opened or not. When a user opens the water outlet valve, the gating switch sends a first electric signal to a processor of the water heater, and the processor determines that the water outlet valve is opened after receiving the first electric signal; when the user closes the water outlet valve, the gating switch sends a second electric signal to the processor of the water heater, and the processor determines that the water outlet valve is closed after receiving the second electric signal.
In one embodiment, the outlet valve includes a cold water inlet, a hot water inlet, and an outlet. The cold water inlet is connected with the cold water inlet pipe, and the cold water inlet pipe can convey cold water to the water outlet valve through the cold water inlet; the hot water inlet is connected with the hot water inlet pipe, and the hot water inlet pipe can convey hot water to the water outlet valve through the hot water inlet; the water outlet is connected to the water outlet pipe, and the water outlet valve mixes the cold water conveyed by the cold water inlet pipe and the hot water conveyed by the hot water inlet pipe through the water outlet pipe and conveys the mixed water flow to the shower head so that the shower head sprays water.
In one embodiment, after the opening of the water outlet valve is detected, the information of the angle of the water outlet valve deviated to the cold water inlet or the hot water inlet is obtained through a preset angle sensor. For example, a user controls the water outlet valve to open by lifting the movable switch of the water outlet valve, and controls the water outlet valve to shift towards the cold water inlet or the hot water inlet by controlling the movable switch of the water outlet valve to move left and right, the cold water inlet and the hot water inlet are symmetrically distributed at two sides of the movable switch, when the movable switch shifts towards one side of the hot water inlet, the angle sensor can acquire angle information of the water outlet valve shifting towards the hot water inlet, for example, the angle information shifts 10 degrees towards the hot water inlet, and send the acquired angle information to the processor and the memory.
In one embodiment, after the outlet valve is opened, the outlet angle of the outlet valve is fixed, and the movable switch of the outlet valve controls the outlet valve to deflect towards the cold water inlet or the hot water inlet, so that the deflection angle of the outlet valve towards the cold water inlet or the hot water inlet is distributed, and deflection angle information is obtained. The cold water inlet and the hot water inlet are symmetrically distributed on two sides of the movable switch, the angle information comprises a first angle for opening the water outlet valve to the cold water inlet and a second angle for opening the hot water inlet, and the water outlet angle of the water outlet valve can be set according to actual conditions. For example, the total offset angle of the outlet valve is 140 degrees, when the position of the movable switch is located at the center of the cold water inlet and the hot water inlet, the offset angle of the cold water inlet and the hot water inlet are both 70 degrees, when the position of the movable switch is more offset to one side of the hot water inlet, and when the opening angle of the hot water inlet is 90 degrees, the offset angle of the cold water inlet is 50 degrees.
In one embodiment, the outlet valve includes a valve port and a valve element, the valve element is used for blocking the valve port so that the outlet valve is closed, when the outlet valve is opened, the valve element moves, and water can flow out from the valve port. The cold water inlet and the hot water inlet are distributed on two sides of the valve core, the offset angle is determined according to the width of the valve opening of the valve core on one side of the cold water inlet or one side of the hot water inlet, the offset angle is in direct proportion to the width of the valve opening, namely the larger the width of the opened valve opening is, the larger the offset angle is. For example, the total width of the valve opening is 2 cm, when the width of the valve opening opened by the valve core on the hot water inlet side is 0.5 cm, the offset angle of the hot water inlet is 45 degrees, and when the width of the valve opening opened by the valve core on the hot water inlet side is 1 cm, the offset angle of the hot water inlet is 90 degrees, which is not limited in this embodiment.
In one embodiment, before angle information of the deviation of the water outlet valve to the cold water inlet or the hot water inlet is obtained, whether the water heater triggers a preset control instruction is judged, and the preset control instruction is used for controlling the water outlet valve to enter an intelligent control mode; and if the water heater is judged to trigger the preset control instruction, executing the step of acquiring the angle information of the deviation of the water outlet valve to the cold water inlet or the hot water inlet. It should be noted that, when a user is in a bathing process, the water heater is not convenient to use due to the fact that the switch of the water outlet valve is required to be frequently regulated and controlled manually, the water outlet valve is controlled to enter an intelligent control mode by setting a preset control instruction, and when the user is judged to be in the bathing process, the water outlet valve is intelligently controlled, so that the water outlet temperature of the shower head is not too high or too low, and user experience is greatly improved.
Wherein, judge whether the water heater triggers preset control command, include: acquiring opening information of the water outlet valve within preset time, and judging whether the opening information meets preset conditions; and if the opening information meets the preset condition, judging that the water heater triggers a preset control instruction. The preset time is the time before the opening of the water outlet valve is detected, for example, 2 minutes before the opening of the water outlet valve, the opening information includes an opening time point, opening times and/or opening duration, the preset condition includes that the opening time point is within a preset time period, the opening times are greater than or equal to the preset times and/or the opening duration is less than or equal to the preset duration, and a user can flexibly set the time.
For example, when a user usually bathes at about 8 pm, the user may set the time period from 7 pm 30 to 8 pm 30 as the preset time period, and when the opening time point of the water outlet valve is within the preset time period from 7 pm 30 to 8 pm 30, it is determined that the water heater triggers the preset control instruction. For another example, when the number of times of opening the water outlet valve within the preset time is 2, which is equal to the preset number of times, it indicates that the user needs to open the water outlet valve many times within a short time, and at this time, it is determined that the water heater triggers the preset control instruction, so as to execute the subsequent steps, so as to control the water outlet valve to enter the intelligent control mode, thereby implementing the intelligent control of the water outlet valve.
In one embodiment, the temperature information of a user who opens the water outlet valve is acquired through a preset infrared sensor, and if the temperature information is greater than or equal to a preset temperature, it is determined that the water heater triggers a preset control instruction. It should be noted that the purpose of collecting the temperature information of the user who opens the water outlet valve is to determine whether the user is in the bathing process, when the user is in the bathing process, the preset infrared sensor directly collects the body surface temperature of the user, if the user is not in the bathing process, the preset infrared sensor directly collects the surface temperature of the outer garment of the user, the body surface temperature is higher, and the surface temperature of the outer garment is lower, so that whether the user is in the bathing process can be distinguished through the temperature information collected by the preset infrared sensor, if the temperature information is greater than or equal to the preset temperature, namely, when the user is judged to be in the bathing process, the preset control instruction is triggered, and the water outlet valve is controlled to enter an intelligent control mode.
In one embodiment, the conductivity of the outer surface of the outlet valve is detected, and if the conductivity is greater than or equal to a preset conductivity, it is determined that the water heater triggers a preset control command. It should be noted that the purpose of detecting the conductivity of the outer surface of the outlet valve is to determine whether the outer surface of the outlet valve is wet, and thus whether the user is bathing. When the user opens the outlet valve in the bathing process, the outlet valve is touched by a hand stained with water, so that the conductivity of the outer surface of the outlet valve is higher, and therefore, if the conductivity is greater than or equal to the preset conductivity, the preset control instruction is triggered when the user is judged to be in the bathing process, and the intelligent control of the outlet valve is realized.
And S102, acquiring a first water inlet temperature at a cold water inlet and a second water inlet temperature at a hot water inlet.
Specifically, a first temperature sensor is installed at the cold water inlet, and a second temperature sensor is installed at the hot water inlet. The first water inlet temperature of the cold water inlet can be quickly and accurately obtained through the first temperature sensor, and the second water inlet temperature of the hot water inlet can be quickly and accurately obtained through the second temperature sensor.
And S103, determining the outlet water temperature of the shower head according to the angle information, the first inlet water temperature and the second inlet water temperature.
It should be noted that information such as the proportion of the inflow of cold water and/or hot water entering the outlet valve can be determined according to the angle information of the deviation of the outlet valve to the cold water inlet or the hot water inlet, so that the temperature of the water flow flowing to the shower head can be determined according to the information such as the proportion of the inflow of cold water and/or hot water, the first inflow temperature and the second inflow temperature, and the outlet temperature of the shower head can be obtained.
In an embodiment, as shown in fig. 2, step S103 includes sub-steps S1031 to S1032.
And step S1031, determining the valve outlet water temperature at the water valve according to the angle information, the first inlet water temperature and the second inlet water temperature.
Determining a first water inflow of cold water, a second water inflow of hot water and a total water inflow of water flow which enter the water outlet valve according to the offset angle of the water outlet valve to the cold water inlet or the hot water inlet; determining a first heat quantity in the cold water according to the first water inlet temperature and the first water inlet quantity, and determining a second heat quantity in the hot water according to the second water inlet temperature and the second water inlet quantity; calculating the total heat quantity in the cold water and the hot water according to the first heat quantity and the second heat quantity; and determining the outlet water temperature of the valve at the water valve according to the total water inflow and the total heat.
It should be noted that, through the preset mapping relationship between the water inflow of the cold water and the hot water and the angle information, the first water inflow of the cold water and the second water inflow of the hot water entering the water outlet valve corresponding to the angle information can be determined, and the total water inflow is the sum of the first water inflow and the second water inflow. The heat is the product of temperature and water yield, therefore, can confirm the first heat in the cold water through first inflow temperature and first inflow, can confirm the valve temperature of going out water of water valve department according to total inflow and total heat.
In one embodiment, the angle information includes a first angle at which the outlet valve opens to the cold water inlet and a second angle at which the outlet valve opens to the hot water inlet; specifically, determining the valve outlet temperature at the water valve comprises: according to the first angle and the second angle, determining the ratio of the water yield of the cold water and the hot water which can pass through the water outlet valve in unit time; and calculating the water outlet temperature of the valve at the water valve according to the water outlet ratio, the first water inlet temperature and the second water inlet temperature.
The ratio of the water yields of the cold water and the hot water which can pass through the water outlet valve in unit time is the ratio of the first angle and the second angle, and the ratio of the water yields may be a fractional ratio, for example, the ratio of the water yields is 1/2, which means that the water yield of the hot water which can pass through the water outlet valve in unit time is 2 times of the water yield of the cold water which can pass through the water outlet valve in unit time, or 3 parts of the water yield of the hot water which can pass through the water outlet valve in unit time, wherein the water yield of the cold water accounts for one part of the water yields, and the water yield of the hot water accounts for two parts of the water yields. Therefore, the valve outlet water temperature T0 at the water valve (T1 a + T2 b)/(a + b) can be calculated from the ratio of the water outlet amount a/b, the first inlet water temperature T1 and the second inlet water temperature T2. For example, if the ratio of the water output is 1/2, the first inlet water temperature is 20 degrees, and the second inlet water temperature is 60 degrees, then the valve outlet water temperature can be calculated to be 46.7 degrees.
In one embodiment, a first water outlet amount of cold water passing through the water outlet valve in unit time is determined according to a first angle, and a second water outlet amount of hot water passing through the water outlet valve in unit time is determined according to a second angle; determining a first heat quantity of cold water in unit time according to the first water inlet temperature and the first water outlet quantity, and determining a second heat quantity of hot water in unit time according to the second water inlet temperature and the second water outlet quantity; and acquiring the total water yield of the water outlet valve in unit time, and calculating the water outlet temperature of the valve at the water valve according to the first heat, the second heat and the total water yield. Note that, according to the first heat amount C1, the second heat amount C2, and the total water yield V0, the valve outlet water temperature T0 at the water valve may be calculated as (C1+ C2)/V0.
And the substep S1032 is used for obtaining the water yield of the water outlet valve in unit time and determining the water outlet temperature of the shower head according to the water yield of the unit time and the water outlet temperature of the valve.
The water yield of the water outlet valve in unit time is related to the opening gear of the movable switch of the water outlet valve and can be detected through the flow meter. In general, the larger the opening gear of the movable switch is, the larger the water yield per unit time at the water outlet valve is, the smaller the opening gear of the movable switch is, and the smaller the water yield per unit time at the water outlet valve is. In the case where the outlet amount per unit time at the outlet valve is small, the proportion of heat lost by the water flowing from the outlet valve to the shower head is large. In addition, when the outlet pipe connecting the outlet valve and the shower head does not pass hot water for a long time, the heat loss of the water flow flowing from the outlet valve to the shower head is also large.
In one embodiment, the total heat of the water flow passing through the water outlet valve in unit time is determined according to the water outlet amount in unit time and the water outlet temperature of the valve; determining the heat loss of the water flow flowing out of the water outlet pipe in unit time to obtain the heat loss; and determining the water outlet temperature of the shower head according to the total heat, the heat loss and the water outlet amount in unit time.
It should be noted that the heat is the product of the water temperature and the water amount, so the total heat C1 of the water flow passing through the outlet valve per unit time is equal to the water outlet amount V1 per unit time multiplied by the valve outlet temperature T0; the heat lost by water flow flowing out of the water outlet pipe in unit time is prestored in the memory, the heat loss can be obtained through multiple measurements, particularly when the room temperature is low or the heat dissipation of the water outlet pipe is large, the heat loss of the water outlet pipe is large, and if the heat loss of the water outlet pipe is ignored, errors exist in the calculation result of the embodiment of the application; according to the total heat C1, the heat loss C2 and the water yield V1 per unit time, the water temperature T2 at the shower head can be calculated to be (C1-C2)/V1. The water outlet temperature of the shower head is obtained through calculation of the total heat and the heat loss of the water flow, the calculation result is more accurate, and the accurate control of the water outlet temperature is facilitated.
And S104, when the outlet water temperature is not within the preset temperature range, adjusting the outlet water valve, so that the outlet water temperature at the adjusted shower head can be within the preset temperature range.
After the outlet water temperature at the shower head is determined, whether the outlet water temperature at the shower head is within a preset temperature range is judged, and the preset temperature range can be flexibly set by a user. If the outlet water temperature of the shower head is within the preset temperature range, the outlet valve does not need to be intelligently adjusted, and if the outlet water temperature is not within the preset temperature range, the outlet water valve is adjusted, so that the outlet water temperature of the shower head after adjustment can be within the preset temperature range, and if a user is in the bathing process, the experience of the user can be greatly improved.
In one embodiment, the step of adjusting the outlet valve comprises: determining a difference value between the water temperature and a preset temperature threshold value to obtain a temperature difference value; and determining the adjusting parameters of the water outlet valve according to the temperature difference, and adjusting the water outlet valve according to the adjusting parameters. The preset temperature threshold can be set according to actual conditions, and optionally, the preset temperature threshold is 42 ℃ and is slightly higher than the average body temperature of a human body. The processor determines the adjusting parameter of the water outlet valve according to the temperature difference value, so that the outlet water temperature at the adjusted shower head can be within a preset temperature range, the water outlet valve is adjusted according to the adjusting parameter, the outlet water temperature at the shower head cannot be too high or too low, and the bathing experience of a user is improved.
Illustratively, the temperature difference is-10 ℃, the adjusting angle of the water valve is determined to be 5 degrees deviated to one side of the hot water outlet according to the temperature difference of-10 ℃, and the water outlet valve is adjusted according to the adjusting parameter, so that the outlet water temperature of the adjusted shower head can be within the preset temperature range. Exemplarily, the temperature difference is 5 degrees centigrade, the adjusting angle of the water outlet valve is determined to be 2.5 degrees centigrade deviated to one side of the cold water outlet according to the temperature difference of 5 degrees centigrade, and the water outlet valve is adjusted according to the adjusting parameter, so that the water outlet temperature of the adjusted shower head can be within a preset temperature range, and the user experience is greatly improved.
In one embodiment, the outlet valve is adjusted for multiple times according to preset adjustment parameters until the outlet temperature of the adjusted shower head is within a preset temperature range. For example, the outlet water temperature at the shower head is 25 degrees celsius, the preset temperature range is (35, 45 degrees celsius), and the preset adjustment parameter is 2 degrees offset to the direction of the middle position of the hot water outlet and the cold water outlet. When the water outlet temperature of the shower head is 25 ℃ and is not within the preset temperature range (35, 45 ℃), the water outlet valve is controlled to deviate 2 ℃ towards the direction of the middle position of the hot water outlet and the cold water outlet, the water outlet temperature of the shower head is calculated to be 28 ℃, the water outlet valve is continuously adjusted according to preset adjusting parameters until the water outlet temperature of the shower head after adjustment can be within the preset temperature range (35, 45 ℃).
According to the control method of the water heater provided by the embodiment, the angle information of the deviation of the water outlet valve after the water outlet valve is opened towards the cold water inlet or the hot water inlet is obtained, the first water inlet temperature of the cold water inlet and the second water inlet temperature of the hot water inlet are obtained, the water outlet temperature of the shower head is determined according to the angle information, the first water inlet temperature and the second water inlet temperature, and when the water outlet temperature is not within the preset temperature range, the water outlet valve is adjusted, so that the water outlet temperature of the shower head after being adjusted can be within the preset temperature range. This application is beaten by the user at outlet valve to showing when high temperature or microthermal water outlet angle, can adjust outlet valve intelligently to the leaving water temperature of control gondola water faucet is located preset temperature range, greatly improves user experience.
