Detailed Description

The invention will be further described with reference to the accompanying drawings in which:

as shown in fig. 1, the core of the apparatus is a controller. After the peripheral signals (such as the climate information of a temperature sensor and the internet, the temperature gears of each load of the product and the use state of a user) are read and logically judged, the control target temperature (such as the water heating temperature, the heat preservation temperature of a toilet seat, the wind temperature of warm air and the like) of each load is intelligently set, and the purposes of comfort, convenience and energy conservation are achieved.

As shown in fig. 2, a flow chart of the function Fc is calculated for the intelligent target temperature. The intelligent target temperature calculation aims to dynamically adjust the control target temperature of each load of a product according to the environment, the climate temperature and the temperature gear selected by a user, and a comfortable experience effect can be achieved without manual intervention.

An example of the target temperature calculation function ft (x, y) is as follows:

t ═ ft (x, y) ═ Ax + By + C. Wherein x is a climate temperature value obtained from the Internet, y is a temperature gear set by a user, and the range of y is 1-5, and represents 1-5 gears respectively. A, B and C are calculation coefficients, wherein A is set to be-0.3, B is set to be 8 and C is set to be 7.5 (different loads and coefficients of calculation formulas can be different according to requirements).

For example, when the obtained climate temperature is 18 degrees celsius and the temperature shift set by the user is 4 shifts, the target temperature T is-0.3 × 18+8 × 4+7.5 — 34.1, that is, the target temperature is 34.1 degrees celsius.

As shown in fig. 3, a flowchart of the product use history learning function Fl is shown. The purpose of the use history learning is to record the use habits of users, mark time periods of the products which are not commonly used and provide the time periods for intelligent power-saving calculation basic information.

Fig. 4 shows a flow chart of the intelligent power saving function Fs. The intelligent power saving aims to set different heat preservation temperatures and even turn off the heater in the period that the frequency of the product used by a user is different according to the use history information so as to achieve the effect of power saving.

As shown in fig. 5, is an overall control flow chart for automatic temperature setting. The method comprises the following specific steps: 1) calling a history learning function Fl to perform use history learning processing; 2) calling an intelligent power saving function Fs, and judging the level of current power saving and the set temperature Ts of a corresponding load by using the latest learning history information; 3) calculating the intelligent target temperature Fc of each load to obtain the intelligent control target temperature Tc of each load; 4) comparing Ts and Tc of each load, and judging the final control target temperature; 5) and performing on-off control of each load heater by using the final control target temperature.

The first embodiment is as follows:

scene: 14:30 afternoon, the learning history of the local air temperature of 28 ℃ and 14: 00-15: 00 is 10 (namely, the local air temperature is not used in the time period for 10 consecutive days), and the toilet seat temperature gear is 1 gear.

The controller calculates an intelligent target temperature (T ═ ft (x, y) ═ Ax + By + C), and obtains that the current target temperature is 30 ℃.

Since the learning history is 10, the intelligent power saving target temperature is 26 ℃ by calculation of the intelligent power saving function Fs.

Through comprehensive judgment, the intelligent power-saving target temperature is found to be lower, and the controller adopts the target temperature of 26 ℃ to control the heater.

Example two:

scene: the time is 7:40 in the morning, the learning history of the local air temperature is 10 ℃ and is 7: 00-8: 00 is 1 (namely the local air temperature is not used in the time period for 1 continuous day), and the toilet seat temperature gear is 4.

The controller calculates an intelligent target temperature (T ═ ft (x, y) ═ Ax + By + C), and obtains that the current target temperature is 38 ℃.

Because the learning history is 1, the intelligent power-saving target temperature and the intelligent target temperature are obtained through calculation of the intelligent power-saving function Fs.

The controller used a target temperature of 26 ℃ for heater control.

In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the claims of the present invention.
