The invention is described in further detail below with reference to the accompanying examples.
As shown in fig. 1, the method for controlling the temperature of an instant heating appliance in this embodiment includes the following steps.
And after the electric appliance receives the liquid outlet command, the electric appliance performs the work of three heating stages. However, in order to avoid damage to the electric appliance due to dry burning, when the electric appliance is used for the first time, a liquid capable of filling the liquid flow passage is first injected into the liquid flow passage of the electric appliance before the first heating stage. The liquid flow capable of filling the liquid flow channel is injected into the liquid flow channel of the electric appliance by controlling the liquid inlet flow and the liquid inlet time. In addition, a first use mark can be arranged in the electric appliance, if the pump body is controlled to work and liquid is injected into a liquid flow channel of the electric appliance, the first use mark is changed, and the liquid inlet step is not needed in the subsequent use process.
A first heating stage: and controlling to carry out full-power heating, and ending the first heating stage and entering a second heating stage when the detected temperature of the liquid outlet end is close to the set temperature or the temperature of the liquid outlet end is stabilized at a temperature lower than the set temperature. The full-power heating is used in the stage, the temperature of the liquid outlet end can reach the set temperature quickly, liquid can be discharged through faster control, the temperature of the liquid can reach the set temperature basically, the situation that the liquid outlet temperature is too low can be avoided, the requirement of people on the liquid outlet temperature is met, and the full-power heating is more humanized.
A second heating stage: the flow is regulated on the set basic flow, the liquid is fed according to the regulated flow, the liquid is heated in full power, the temperature T of the liquid outlet end is detected in real time, when the temperature difference between the temperature T of the liquid outlet end and the set temperature T0 is smaller than a set temperature difference threshold value Tz, namely T0-T is smaller than Tz, the second heating stage is ended, and the third heating stage is started, wherein the Tz is 2 ℃ in the embodiment. In the stage, the temperature of the liquid outlet end can be ensured to reach the set temperature on the basis of adjusting the proper flow, and the liquid outlet temperature requirement is met.
A third heating stage: and detecting the liquid inlet temperature in real time, and adjusting the heating power according to the PID control method of the set temperature according to the real-time liquid inlet temperature, the set temperature and the current flow. After the temperature of the liquid outlet end is stable and reaches the set temperature, judging whether the current heating power is the maximum heating power of the electric appliance, and if so, controlling the electric appliance to perform heating operation according to the current flow; if not, the flow is increased according to the set flow regulation amount, then the heating power is adjusted according to the PID control method of the set temperature, the process is circulated until the maximum heating power is reached, and then the corresponding maximum flow under the current water inlet temperature condition is obtained, so that the electric appliance can work in the maximum flow state of the maximum power and the corresponding working condition, the waiting time of a user is reduced, and the use experience is better. In addition, each working parameter corresponding to the working condition is recorded, the adjusted working parameters corresponding to various working conditions can be recorded in the long-term use process, the work can be directly carried out according to the recorded working parameters in the subsequent working process conveniently, and the control is simpler.
In order to output liquid for users as soon as possible under the condition of basically meeting the set temperature, different liquid outlet strategies need to be considered for different liquid inlet temperature conditions. Before the first heating stage is started, firstly, calculating the temperature difference Tc between the current liquid outlet end temperature T and the set temperature T0, wherein Tc is T0-T; different controls are respectively carried out according to different situations. In the following, a > B > 0 ℃, in this example a ═ 30 ℃ and B ═ 10 ℃.
Case 1: if Tc is more than A, the liquid is not fed into the liquid flow channel of the electric appliance in the first heating stage process, namely the pump body for feeding the liquid is controlled not to work, and the corresponding electric appliance cannot output the liquid at the moment. In this embodiment, for the case 1, the pump body for controlling the liquid feeding does not work, that is, the liquid in the liquid flow channel in the electrical appliance is directly heated, the amount of water in the liquid flow channel is very small, the full power heating is used in the first heating stage process, the temperature rise speed of the liquid in the liquid flow channel is very fast, if the real-time Tc is less than or equal to 2 × Tv, the first heating stage is ended, and correspondingly, in the second heating stage, the flow rate is increased on the set basic flow rate; where Tv is a temperature rise value in the current unit period, and the unit period in the temperature rise value in the unit period may be a power adjustment period of the heating device, and in this embodiment, the unit period is 0.2 seconds.
Case 2: if the B is less than or equal to the Tc and less than or equal to the A, the electric appliance is controlled to feed liquid into a liquid flow channel of the electric appliance according to the minimum flow after receiving a liquid outlet command, the corresponding electric appliance outputs the liquid outwards according to the flow, and the flow is increased in an acceleration mode according to the set flow in the process of the first heating stage until the flow reaches the set basic flow.
Case 3: if Tc is less than B, the electric appliance directly enters liquid into the liquid flow channel of the electric appliance according to the set basic flow after receiving the liquid outlet command, and the corresponding electric appliance also outputs the liquid according to the flow and keeps the flow in the process of the first heating stage.
For the case 2 or the case 3, the pump body for controlling liquid inlet works, namely the electric appliance outputs liquid in real time, but the liquid inlet temperature is closer to the set temperature, full-power heating is used in the process of the first heating stage, the liquid in the liquid flow channel can also be quickly close to the set temperature speed, and if the real-time Tc is less than or equal to 2 Tv or the real-time Tc is kept unchanged, the first heating stage is ended; if Tc is less than or equal to 2 Tv, increasing the flow rate on the set basic flow rate in the second heating stage; if Tc > 0 and remains constant, the flow rate is reduced at the set base flow rate during the second heating phase.
For the above 3 cases, it is certain that the liquid is to be output after the first heating stage is ended, and Tc ≦ 2 × Tv is used as a determination condition for ending the first heating stage, so that the situation that the temperature of the liquid outlet end is over-temperature can be well avoided, that is, the situation that the temperature of the output liquid is higher than the set temperature is avoided, especially when the amount of liquid required by the user is small, if the temperature of the output liquid is over-temperature, the experience of the user is greatly affected, and the control condition for ending the first heating stage effectively avoids the situation.
The temperature control method of the instant heating type electric appliance can be applied to various instant heating type heating electric appliances, such as an instant heating type water inlet machine. According to the temperature control method of the instant heating type electric appliance, the heating process is divided into three heating stages, the first heating stage works by using full power, so that the temperature of the liquid outlet end can quickly reach the set temperature, and the waiting time of a user is reduced. And in the second heating stage, the temperature of the discharged liquid can quickly and accurately reach the set temperature on the basis of adjusting the water quantity. In the third heating stage, the temperature of the liquid outlet is guaranteed to accurately reach the set temperature, meanwhile, the flow of the liquid outlet is adjusted to be the maximum, the liquid outlet speed is guaranteed, the waiting time of a user is reduced, the use is humanized, and the user experience is better.
