Description
[technical field]
The present invention relates to the household electrical appliance that head constantly swings back and forth, relate in particular to the household electrical appliance that to follow the yaw air-supply of human body present position automatically or send heating installation, like electric fan and electric heater; The invention still further relates to this automatically regulating swaying angle of household appliance to adapt to the method for position of human body.
[background technology]
Prior art household electrical appliance such as electric fan, electric heater etc. the function of all shaking the head mostly; The mechanism that realizes this function is an oscillating mechanism; The prior art oscillating mechanism is the toggle that reducing motor drives, and promptly with toggle the continuous rotation motion of motor output shaft is changed to swinging back and forth of head; Said toggle is a four-bar mechanism, and the pivot angle size depends on the length of each bar in the mechanism, because the length of each bar is immutable, so swaying angle is non-adjustable.So optimal swaying angle is all the time, to have many people to seek redress from machinery and electrical equipment two aspects from minimum to maximum step-less adjustment, and for example certain mechanism of usefulness makes the variable-length of crank, and complicacy is difficult to practical application but this understands too; Or; Change the time of commutating when shaking the head with two-way controlled reducing motor; Though this structure is simpler, still exist predefined swaying angle not move and append the disadvantage of adjustment in good time with personnel increase and decrease or position, ease of use has obviously just been had a greatly reduced quality.
Prior art has the people to propose to adjust automatically when method with infrared automatic tracking realizes shaking the head its angle; Like Chinese utility model patent " infrared tracking shake the head automatic fan "; The patent No. is ZL 91219851.6; Its principle is to receive the also difference of human body infra-red intensity with two cover infrared receiving devices, judges moving of human body through computing.Yet this tracking mode only is applicable to a people, to it is just powerless more than two people, so this patent fails to apply so far; Secondly, two cover infrared receiving devices also seem too numerous and diverse.
Chinese for another example utility model patent " the infrared tracking head-shaking device of intelligent fan "; The patent No. is ZL93202860.8, and this head-shaking device comprises sensor, a cover electronic control circuit and a micromotor oscillating mechanism that is mounted with guiding mechanism, hot electric infrared receiving tube HW composition; Though this utility model patent is easy to manufacture, cost is low and be convenient to enforcement; Can effectively shake the head to single body and many human body tracking automatically in the panning angle; Automatically panning angle is the external both sides of single body or many human bodies and the angle generation natural wind effect that the fan screen center is formed, but this utility model patent has following weak point:
The panning angle scope of one, making is less than 180 degree;
Two, changeing full effective panning angle and when effectively still having human body outside the panning angle, fan head does not continue to rotate to original direction when fan head, but is yaw round about, makes the outer human body of effective panning angle be without access to the wind that fan is produced by boasting;
Even three can satisfy top 2 points; The also not open fan head that how to guarantee of this utility model patent can be dried by yaw in the minimum swaying angle of whole position of human body; Blow on one's body the user to guarantee that wind that this fan sees off is concentrated to greatest extent, avoid blowing to the waste that energy is caused in the no man's land;
Four, also not explanation of this utility model patent, after personnel amount and shift in position, how this fan shakes the head just can be guaranteed concentrated to greatest extent the blowing on one's body the user of wind that this fan is seen off.
[summary of the invention]
