Description
Technical field
The present invention relates to a kind of automatic speed regulating fan and automatic speed-regulating method thereof, particularly relate to a kind of automatic speed regulating fan and the automatic speed-regulating method thereof that are applicable to household human body.
Background technique
Fan is widely used in the furniture life in modern times, basic is the indispensable electrical equipment of every household, fan is the different demands meeting user, reach different rotating speeds, be provided with control gear, existing fan mostly is classification regulation and control or the regulation and control rotation speed of the fan according to the built-in control program rule of fan, although can meet certain user demand, but still intelligence not, the demand of modern society's and hommization intelligent to household electrical appliances can not be met.
Also have some automatic speed regulating fans or Intelligent speed regulation fan in existing fan, but often only environmentally temperature carry out the adjustment of wind speed or rotation speed of the fan.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of more conforming and the automatic speed regulating fan of body sense demand and automatic speed-regulating method thereof.
The technical solution used in the present invention is as follows: a kind of automatic speed regulating fan, is characterized in that: comprise humidity measuring circuit, for detecting ambient humidity and being converted into digital signal as the index controlling fan operation.
As preferably, described humidity measuring circuit comprises humidity transducer and coupled A/D converter; Described A/D converter is connected with the running control circuit of fan.
As preferably, described humidity transducer is macromolecule humistor.
As preferably, also comprise temperature sensing circuit, be converted into digital signal for testing environment temperature, as the index controlling fan and run.
As preferably, described temperature sensing circuit comprises temperature transducer.
As preferably, described temperature transducer adopts DS18B20 temperature transducer, adopts monobus lin protocol.
A kind of automatic speed-regulating method based on above-mentioned automatic speed regulating fan: automatically regulate rotation speed of the fan according to human body sendible temperature under specific environment temperature and humidity condition.
Human body is the need of blowing fan, and need to blow great wind, directly feel it is " temperature is high " or " heat ", the most directly performance is ambient temperature, therefore in the prior art, so-called automatic speed regulating fan or Intelligent speed regulation fan often just environmentally temperature wind speed or rotation speed of the fan are regulated, and have ignored the impact of other factors.
But under same ambient temperature, different people to temperature or cold and hotly may have different impressions, and we are referred to as sendible temperature in the present invention.
When ambient humidity is below 30%, human body sensory environment is too dry, and can cause floor metope cracking, human body cell dewaters; When ambient humidity is between 30% to 40%, human body sensory environmental drying; When ambient humidity is between 40% to 60%, human body sensory is suitable for, clearly comfortable; When ambient humidity is between 60% to 80%, human body sensory is moist, and clothes, body of wall are mouldy, bacteria breed; When ambient temperature is more than 80%, human body sensory is too moist, and sweat evaporation is not gone out, and easily heatstroke and rheumatic arthritis occurs.Therefore, ambient humidity has very important impact to human body sendible temperature.Ambient humidity affects surrounding environment and human feeling, and the most whether impression is moist.When summer, for human body, the most directly impression is dry, suitable, moist or stuffy, but have ignored moist degree in other words ambient humidity on the impact of fan blowing human feeling effect.
And to blowing electric fan, when humidity is between 30% to 80%, just needing to consider blowing fan, the super fan that goes beyond the scope just does not have great meaning.
In summer, the human feeling under different sendible temperature is: when temperature is at 13 degrees Celsius to 18 degrees Celsius, human body sensory terribly cold (the cold dead person of meeting); When temperature is at 18 degrees Celsius to 20 degrees Celsius, human body sensory cold (can be sick), clothes is worn very thick or is drilled in quilt, can accept reluctantly; When temperature is at 20 degrees Celsius to 25 degrees Celsius, human body sensory is somewhat cold, and clothes of adding some points is best, can accept; When sendible temperature is at 25 degrees Celsius to 26 degrees Celsius, human body sensory is cooled off oneself; When sendible temperature is at 27 degrees Celsius to 30 degrees Celsius, human body sensory heat; When sendible temperature is at 30 degrees Celsius to 33 degrees Celsius, human body sensory is awfully hot, needs air-conditioning or fan; When sendible temperature is at 33 degrees Celsius to 35 degrees Celsius, human body sensory is overheated, needs to have a shower; When sendible temperature is at 35 degrees Celsius to 37 degrees Celsius, human body sensory is too warm, needs frequently to have a shower; When sendible temperature is greater than 37 degrees Celsius, human body sensory is very hot, can cause deaths.It can thus be appreciated that sendible temperature, between 27 degrees Celsius to 33 degrees Celsius, just needs blowing fan.
As shown in Table 1, be the sendible temperature Distribution Value of human body human body under ambient temperature and ambient humidity integrated condition.
Table one
As preferably, according to human body sendible temperature, fan is divided into N number of speed governing gear, the rotating speed that N number of gear corresponding fan N kind is different; 2≤N≤8.
As preferably, described N=6, setting means is: 27 DEG C of < sendible temperature≤28 DEG C are 1. shelves; 28 DEG C of < sendible temperature≤29 DEG C are 2. shelves; 29 DEG C of < sendible temperature≤30 DEG C are 3. shelves; 30 DEG C of < sendible temperature≤31 DEG C are 4. shelves; 31 DEG C of < sendible temperature≤32 DEG C are 5. shelves; 32 DEG C of < sendible temperature≤33 DEG C are 6. shelves; 1. shelves rotating speed is minimum, and rotating speed increases to 6. shelves successively, and 6. shelves rotating speed is maximum.
As preferably, specifically set according to different geographical, different crowd and the varying environment concrete rotating speed size to each gear.
Compared with prior art, the invention has the beneficial effects as follows: environmentally humidity is on the impact of body sense, consider ambient humidity and ambient temperature to the impact of body sense, thus human body sendible temperature is shown as speed governing operation external environment condition humidity and ambient temperature carrying out judging to control fan, more conform and body sense demand.
