Abstract
The utility model discloses a human-body sensing and temperature control electric fan which comprises a fan body driven by a motor, a temperature controller, a temperature sensor and a pyroelectric infrared sensor. Due to the fact that the human-body sensing and temperature control electric fan comprises the temperature controller, the temperature sensor and the pyroelectric infrared sensor, when temperature detected by the temperature sensor is higher than a set temperature and the pyroelectric infrared sensor senses a human body in a work range, a return circuit of the motor of the fan body is connected, the fan body starts working, when the human body is out of the work range, a contact inside the pyroelectric infrared sensor is disconnected in delay mode, the return circuit of the motor of the fan body is powered off, and therefore not only is control convenient, but also energy conservation and environment pollution are benefited because power is off when people leave.
Description
Technical field
The utility model relates to the electric fan field, relates in particular to a kind of body sense and temperature control electric fan.
Background technique
Along with popularizing of air-conditioning, many families have all loaded onto air-conditioning, and electric fan is eliminated by increasing family.Although air-conditioning has diversified function, but also some people is because blow for a long time air-conditioning or be not suitable with the temperature difference of indoor and outdoor, got air-conditioning sickness, they are in order to spend the weather of sweltering heat in summer, have to electric fan is taken out use, but traditional electric fan is owing to exist function simple, and the drawbacks such as inconvenient operation can not satisfy people's needs.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of body sense and temperature control electric fan is provided, can according to the unlatching of temperature and human body induction control fan, uses easy to operate.
For solving the problems of the technologies described above, the technical solution of the utility model is: body sense and temperature control electric fan comprise that by motor-driven fan body described body sense and temperature control electric fan also comprise:
Temperature controller and the temperature transducer that is electrically connected with described temperature controller, described temperature transducer is for detection of Current Temperatures, Current Temperatures and setting temperature that described temperature controller is used for temperature transducer is detected compare, described temperature controller also is electrically connected with the coil of a relay, and the normally opened contact of described relay is electrically connected on the electric motor loop of described fan body;
Thermoelectric Infrared Sensor, an inner contact of described Thermoelectric Infrared Sensor is serially connected on the electric motor loop of described fan body.
Owing to adopted technique scheme, the beneficial effects of the utility model are: the utility model is owing to installed temperature controller, temperature transducer and Thermoelectric Infrared Sensor, the Current Temperatures that detects when temperature transducer is higher than setting temperature, and Thermoelectric Infrared Sensor is at the operating range internal induction during to human body, the electric motor loop of fan body is connected, and fan body is started working; When human body left operating range, the inner contact of Thermoelectric Infrared Sensor time-delay disconnected, and made the electric motor loop outage of fan body, and not only control is convenient, and the people walks outage and is conducive to energy-conserving and environment-protective.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model embodiment's circuit theory diagrams;
Embodiment
As shown in the figure, body sense and temperature control electric fan comprise by motor-driven fan body, and body sense and temperature control electric fan also comprise:
Temperature controller and the temperature transducer that is electrically connected with temperature controller, temperature transducer is for detection of Current Temperatures, Current Temperatures and setting temperature that temperature controller is used for temperature transducer is detected compare, temperature controller also is electrically connected with the coil of a relay K A, and the normally opened contact of relay K A is electrically connected on the electric motor loop of fan body;
Thermoelectric Infrared Sensor, an inner contact K1 of Thermoelectric Infrared Sensor is serially connected on the electric motor loop of fan body.
Working procedure of the present utility model is:
Press power switch SB, temperature controller must be established beginning work by cable, power supply indicator HL1 is bright, if temperature transducer detects the setting temperature that Current Temperatures is higher than temperature controller, and an inner contact closure of temperature controller, the coil of relay K A gets electric, the normally opened contact of relay K A is closed, at this moment, if Thermoelectric Infrared Sensor detects nobody in the operating range, electric motor loop is obstructed, and fan body does not turn; If Thermoelectric Infrared Sensor detects the people is arranged in the operating range, then Thermoelectric Infrared Sensor inner contact K1 is closed, and the electric motor loop of fan body is closed, and fan is started working, and simultaneously, the work indicator light HL2 of fan is bright; Fan body is in operation process, if Thermoelectric Infrared Sensor detects nobody in the operating range, then the inner contact K1 of Thermoelectric Infrared Sensor time-delay disconnects, and delay time is 40 seconds, the electric motor loop outage, and machine operation tutorial light HL2 goes out.
This shows that two necessary conditions that satisfy fan body work are: 1. Current Temperatures is higher than the setting temperature of temperature controller; 2. Thermoelectric Infrared Sensor detects the people in the operating range, Neither of the two can be dispensed.
The utility model is owing to installed temperature controller, temperature transducer and Thermoelectric Infrared Sensor, the temperature that detects when temperature transducer is higher than setting temperature and Thermoelectric Infrared Sensor at the operating range internal induction during to human body, the electric motor loop of fan body is connected, the electric fan body is started working, human body leaves in the operating range, the inner contact time-delay of Thermoelectric Infrared Sensor disconnects, make the electric motor loop outage of fan body, not only control is convenient, and the people walks outage and is conducive to energy-conserving and environment-protective.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
