Technical Field

The invention relates to the technical field of instant heating, in particular to an instant heating device, a control method and a control device thereof, a water treatment device and a medium.

Background

In actual product use, the instant heating pipe and the water outlet pipe of the water dispenser are generally filled with residual water, and the temperature of the residual water is uncertain due to different use conditions. For example, when the water dispenser is kept still for a long time, the temperature of the residual water in the pipe is closer to the room temperature; if the user just finishes boiling water at 90 degrees, the temperature of the residual water in the pipe approaches to 90 degrees. The water dispenser is different in structural design according to different water dispensers, namely the volume of the heat pipe and the volume of the water outlet waterway are added up to reach several milliliters to dozens of milliliters, and for 200 milliliters of water discharged in a single time in a water receiving scene of a user who is commonly used, the temperature accuracy of water in a cup of the user can be greatly influenced due to different temperatures. For example, a user sets a water outlet temperature of 80 degrees, if the temperature of the residual water in the pipe is 4 degrees, the water temperature in the cup after the user has discharged 200 milliliters of water may be only 70 degrees, and if the temperature of the residual water is 90 degrees, the water temperature in the cup after the user has discharged 200 milliliters of water may reach 85 degrees, and the water demand of the water temperature in the cup of 80 degrees, which is required by the user, cannot be well met.

When the second energy is equal to the first energy, the temperature compensation is ended.

It should be noted here that the instant heating device includes a water pump, and the instant heating device implements different voltage outputs to the water pump by adjusting a driving value, where the driving value may be a voltage or a current. The driving value and the water flow speed of the water pump have a certain corresponding relation, and specifically, the driving value and the water flow speed of the water pump are close to a linear relation. Based on the characteristic, the water temperature in the cup is compensated from the angle of energy conservation, the lost energy is compensated back, or the excessive energy is released, so that the accuracy of the water temperature in the cup is improved.

According to the technical scheme, the first energy and the second energy can be determined only according to the product of the difference value of the target outlet water temperature and the current outlet water temperature and the driving value of the instant heating device. Therefore, the calculation speed is improved, and the cost is saved because a flow detection device is not required.

In any of the above technical solutions, the step of determining the target outlet water temperature according to the set temperature specifically includes: acquiring dissipation temperature; and determining the target outlet water temperature according to the set outlet water temperature and the dissipation temperature.

In the technical scheme, the target outlet water temperature is determined according to the set temperature. By presetting the dissipation temperature and receiving a water outlet instruction, the dissipation temperature is obtained. And determining the target outlet water temperature according to the dissipation temperature and the set outlet water temperature. Wherein the dissipation temperature, i.e. the temperature of the water coming out of the instant heating device, is lost from passing through the water outlet temperature detection device to falling to the bottom of the cup.

In addition, the volume of the residual water in the heating device and in the water outlet pipeline can reach several milliliters to tens of milliliters, so that the accuracy of the temperature of the water in the cup of the user is greatly influenced. The difference value between the target outlet water temperature and the residual water temperature is calculated, the temperature compensation value is determined according to the difference value between the target outlet water temperature and the residual water temperature, and then the compensation temperature is determined according to the temperature compensation value and the target outlet water temperature so as to compensate the temperature dissipation in the pipeline and the air. By the control method of the instant heating device, the temperature of the outlet water can be controlled by combining the temperature of the residual water, the water temperature in the cup is compensated from the angle of energy conservation by taking the accuracy of the water temperature in the cup as a control target, the lost energy is compensated back, or the excessive energy is released, so that the accuracy of the water temperature in the cup is improved.
