Example 1: with reference to fig. 1-4, the present application is based on such a bathroom heater: the bathroom heater main body is internally provided with a blowing motor, a wind wheel, a motor rotating speed control unit, a bathroom heater heating body temperature control unit, a temperature sensor A, a temperature sensor B and a bathroom heater main control unit, wherein the motor rotating speed control unit is used for controlling the rotating speed of the blowing motor, and the blowing motor is a driving device of the wind wheel; the bathroom heater heating element temperature control unit is used for controlling the temperature of the bathroom heater heating element; the temperature sensor A is arranged in the air inlet area of the bathroom heater and used for detecting and feeding back the temperature Ta of the air inlet area of the bathroom heater; the temperature sensor B is arranged in the air outlet area of the bathroom heater and used for detecting and feeding back the temperature Tb of the air outlet area of the bathroom heater, and the motor rotating speed control unit, the bathroom heater temperature control unit, the temperature sensor A and the temperature sensor B are respectively in signal connection with the bathroom heater main control unit.
This application is applicable to when bathroom heater usage pattern changes, and bathroom heater usage pattern changes, mainly indicates to increase the bathroom heater behind the bath and blow the wind speed of blowing so that dry body and blow and send out, and the wind speed of blowing improves the back, can influence the temperature of blowing.
A bathroom heater control method with an intelligent body drying function comprises the following steps:
setting the temperature range suitable for the user to be Ts, and when the user starts a body drying mode, sending a signal to a motor rotating speed control unit by a bath heater main control unit to increase the rotating speed of a motor so as to increase the air supply speed and the air supply distance of the bath heater;
the temperature sensor A detects the temperature Ta of the air inlet area of the bathroom heater and feeds the temperature Ta back to the bathroom heater main control unit, and the bathroom heater main control unit compares the Ta with Ts:
when Ta is smaller than the Ts range, the bath heater main control unit sends a signal to the bath heater heating body temperature control unit, the temperature of the bath heater heating body is adjusted to be maximum, and the temperature is rapidly increased;
when Ta is larger than the range of Ts, namely the room temperature is too high, the bath heater main control unit sends a signal to the bath heater heating body temperature control unit to lower the temperature of the bath heater heating body, so that the electric energy is saved, and meanwhile, the room temperature is slowly reduced, and the discomfort of a user is prevented;
when Ta is in the range of Ts, the temperature sensor B detects the air outlet area of the bathroom heater and feeds back the temperature Tb to the main control unit, and after the main control unit receives Tb fed back by the temperature sensor B, the main control unit feeds back Tb by the formula Tx = x Tb m N calculating the temperature Tx at the distance X from the air outlet of the bathroom heater, and comparing Tx with the temperature Ta fed back by the temperature sensor A: if Tx is smaller than Ta, the bath heater main control unit sends a signal to the bath heater heating body temperature control unit to adjust the temperature of the bath heater heating body; then the temperature sensor A and the temperature sensor B continuously detect Ta and Tb, continuously judge Tx and Ta until Tx is greater than or equal to Ta, and end the heating process of the bathroom heater heating element; if Tx is larger than or equal to Ta, the bath heater main control unit does not send a signal to the bath heater heating body temperature control unit, and the temperature of the bath heater heating body is kept unchanged; wherein, the formula Tx = x Tb m N is obtained by experimental data analysis and simulation, X is defined as the distance between a user and the air outlet of the bathroom heater, and m and n are constants;
the above process is continuously operated in the whole body drying process, the temperature is regulated and controlled to be Ta in the Ts range, and Tx is close to Ta.
When using the body function futilely, the bathroom heater wind speed of blowing can improve, and bathroom heater air-out zone temperature Tb can receive the influence this moment, and then influences the temperature in the bathroom in other places, including user's temperature Tx and bathroom heater air inlet zone temperature Ta. The temperature of the bathroom heater heating body is controlled in a secondary mode through comparing the temperature of the bathroom heater air inlet area with the temperature range suitable for the user and properly combining the comparison of the temperature Ta of the bathroom heater air inlet area with the temperature Tx of the user, the regulation and control process is stable, the fluctuation range of the temperature of the user is effectively reduced, the temperature in the bathroom can be favorably regulated within the temperature range suitable for the user, and the temperature range suitable for the user is provided for the userBetter use experience. And the user temperature is added in the temperature comparison, so that the temperature regulation and control in the body drying mode are more reasonable. The temperature Ta of the air inlet area of the bathroom heater and the temperature Tb of the air outlet area of the bathroom heater are easy to detect and obtain through the temperature detection sensors, and the temperature Tx of a user is not easy to obtain. Wherein the relation Tx = xTb m N is obtained through experimental data analysis and simulation, the temperature near the air outlet of the bathroom heater is converted into the temperature blown to the body of the user, and the effect of small calculated amount and more direct effect is achieved in the actual use process.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. However, any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present invention are within the protection scope of the technical solution of the present invention.
