Description
The present invention relates to air conditioner (below be called " air conditioner "), particularly relate to regulating the control that air blows out wind direction.
Air conditioner in the past is installed with several pieces wind direction boards usually on the adjusting air that is used for being cooled, heating or to dehumidify blows to by the blow-off outlet of the chamber of air-conditioning.
About can being adjusted to the blow-off direction of regulating air, this wind direction board reaches above-below direction by adjusting.Here the direction of wind direction board all is to use according to user's wish manually to adjust usually.In addition, also have a kind of as put down in writing on the fair 3-54262 communique of spy the sort of can automatically adjust wind direction board about on lower angle, in the hope of pursuing the comfortable air conditioner of air-conditioning.
Yet, how to control wind direction so that the people feels the most comfortable, technology in the past fails to provide gratifying wind direction control.
For example, when carrying out cooling operation (when outdoor temperature is high), just also can make us feeling nice and cool, in addition chilled adjusting air is blowed to human body, more can make the people feel nice and cool to user's air-supply.But, low if the temperature of this adjusting air was compared with outside air temperature, and the people directly contacts this cooling air for a long time, will make the person uncomfortable.
And carrying out heating when running, and if the temperature of regulating air always can not be heated to (promptly about more than 20-25 ℃) more than the design temperature, directly blowing to human body even will regulate air, the people does not have air conditioner just in the sensation of heating yet.
If but carrying out heating ground temperature height of when running, the temperature of air is slightly lower also to make the people just feel in heating even regulate, on the contrary, if ground temperature is low, the temperature of regulating air so will be higher, otherwise be difficult to give the sensation of heating.
In other words, where indoor the people be in, this point becomes a key factor of carrying out the control of comfortable wind direction, and in addition, the temperature on ground when ground heating utensil (particularly use winter electric heating carpet etc.) also is to make the feel comfortably cool key factor of degree of people.And considered residing position of people (user) and the laggard sector-style of surface temperature to control, this was not having in the past.
Therefore, the objective of the invention is to, make the control of air conditioner wind direction is accomplished suitably to carry out under the situation of the present position of having considered the people and ground plate temperature etc.
Air conditioner of the present invention can be regulated air to being supplied by the air conditioning chamber, and have the flow direction changer that the blow-off direction of air is regulated in any change.This air conditioner also has, radiation temperature transducer, and it has directive property and can measure by the surface temperature of air conditioning chamber in measurement category; Control device, it can handle above-mentioned flow direction changer to change the blow-off direction of above-mentioned adjusting air according to the temperature that above-mentioned radiation temperature transducer records.
In addition, air conditioner of the present invention can also reach design temperature to being regulated the temperature of air in the room by air conditioning chamber's supply, and the 1st flow direction changer that the blow-off direction with this adjusting air changes arbitrarily to the left and right, and the blow-off direction that will regulate air the 2nd flow direction changer of change arbitrarily up and down; This air conditioner also has: the 1st control device, and can be according to being handled the 1st flow direction changer that changes to the left and right in order to the blow-off direction that will regulate air by the temperature of air conditioning chamber and design temperature; In measurement category, have directive property and also can measure the radiation temperature transducer of the surface temperature in air-conditioning object room; The 2nd control device can be handled the 2nd flow direction changer that changes up and down in order to the blow-off direction that will regulate air according to the temperature that this radiation temperature transducer records.
And when being reached design temperature by the room temperature of air conditioning chamber, the 1st control device can be handled the 1st flow direction changer, and to make the blow-off direction of regulating air be that the center is expanded to the left and right with the directive property direction of radiation temperature transducer.
In addition, when by the surface temperature of air conditioning chamber low the time, the 2nd control device can be handled the 2nd flow direction changer so that regulate the blow-off direction tendency ground side of air.
Air conditioner of the present invention has in order to measuring surface temperature and to have the radiation temperature transducer of directive property, controls the angle that the wind direction that can change wind direction is adjusted plate according to the direction of the directive property direction indication of radiation temperature transducer.
Radiation temperature transducer is used for measuring surface temperature so that the control room temperature, its pointing direction is usually towards the many directions of people, therefore, control wind direction, just can correctly control wind direction towards people or unmanned direction are arranged by the directive property direction of utilizing this radiation temperature transducer.
For example, begin soon, when room temperature does not reach design temperature as yet, allow wind, can give comfort to human body at cooling operation.At this moment, because wind direction is towards the pointing direction of radiation temperature transducer, so wind energy enough blows to people's direction.And after room temperature reached design temperature, at this moment wind blowed to human body again, and the people is felt under the weather, and at this moment, can make wind direction towards the pointing direction that is different from radiation temperature transducer, so that wind can not blow to human body.
In addition, device of the present invention can be adjusted wind direction according to the measured surface temperature of radiation temperature transducer.For example, when surface temperature is crossed and hanged down in carrying out the heating running,, ground wind direction can be adjusted to than common direction more towards the below for being warmed.Perhaps, surface temperature is crossed when hanging down in cooling operation, wind direction can be adjusted to than common direction more towards the top in order to make the unlikely cold excessively in ground.

Fig. 1 is the oblique view of indoor unit that shows the air conditioner of the embodiment of the invention.In Fig. 1, indoor unit 1 is installed on the suitable high position of indoor wall, is provided with blow-off outlet 3 and radiation temperature transducer 5 in the bottom of this indoor unit 1.
In blow-off outlet 3, for example be the up-down wind direction board 7 of 2 interlocks but be provided with what be used for wind direction is changed on above-below direction, and be used for multi-disc left and right sides wind direction board 9 that wind direction is changed on left and right directions.
Left and right sides wind direction board 9 is divided into again that the left-half of blow-off outlet among the figure is provided with can interlock left side wind direction board 91, and right half part be provided with can interlock totally two groups of right side wind direction board 9r.
These wind direction boards can be with manually coming to move it, also automatically controlling party to.When controlling automatically, up-down wind direction board 7 is driven by motor 11 (the 2nd flow direction changer), and left side wind direction board 91 is driven by motor 13, and right side wind direction board 9r is then driven by motor 15. Motor 13 and 15 has constituted the 1st flow direction changer.
Fig. 2 is the schematic diagram of above-mentioned air conditioner internal structure.In Fig. 2, air conditioner is made of indoor unit 1 and outdoor unit 21.In indoor unit 1, be provided with control device, indoor blower 23 and the indoor heat converter 25 that to narrate the back.In outdoor unit 21, be provided with the converter 27, compressor 29, accumulator 31, cross valve 33, outdoor heat converter 35 and the electrodynamic type expansion valve 39 that are controlled by above-mentioned control device.These devices have the refrigerant pipe to be connected into the ring-type pipeline, have constituted freeze cycle.
Above-mentioned control device has microcomputer 41 (constituting the 1st control device, the 2nd control device), though it is controlled whole air conditioner, is described as follows in this only just relevant with the present invention item.
Above-mentioned microcomputer 41 receives the signal of expression surface temperature from radiation temperature transducer 5 theres, receive the signal of expression room temperatures from temperature sensor 45 there, and receive the signal of various setting values such as various running control signals from remote controller 49, setting value at room temperature and expression room temperature (temperature around the remote controller 49) from signal receiver 47 theres.
Then, this microcomputer 41 is handled as described later according to above-mentioned received signal, drives wind direction board drive motors 11,13 and 15 according to result again, in order to the control wind direction.
In addition, when this microcomputer 41 is received the signal of directive property direction from the appointment radiation temperature transducer of remote controller 49 (radiation temperature transducer 5 towards), will drive motors 17, so that radiation temperature transducer 5 pointing directions are towards appointed direction, meanwhile, light the light emitting diode 19 of this direction of expression.
Fig. 3 shows that microcomputer 41 carries out the flow chart of the action of wind direction control.In the figure, when selecting automatic wind direction to control according to the control of remote controller signal, just begin to carry out this kind wind direction control (step S1).At first, according to room temperature signal, judge whether room temperature reaches design temperature (step S2) from temperature sensor 45 or remote controller 49; As judged result is not reach design temperature, and that just means now start just soon, indoor fully not warming as yet (during heating) or cool off (during refrigeration).At this moment, make left and right sides wind direction board 9 parallel, and make of the sensing of this left and right sides wind direction board 9 towards radiation temperature transducer 5.(step S3)
Here, radiation temperature transducer 5 is used for detecting surface temperature, and if detected surface temperature is that the surface temperature of people in the place arranged, then ideal to carrying out comfort temperature control.In most cases, the pointing direction of radiation temperature transducer 5 all is towards the place that the people is often arranged.Therefore, in step S3, make the pointing direction of left and right sides wind direction board 9 towards radiation temperature transducer 5, this means before room temperature reaches design temperature during in have warm braw (during heating)/cold wind (during refrigeration) always and blow to the people, give comfort.
At this moment, up-down wind direction board 7 is towards common direction (step S4).Here so-called " direction usually " with reference to Fig. 4, is meant direction 2. among Fig. 4 during heating, promptly oblique below direction; Be meant direction 5. among Fig. 4 during refrigeration, i.e. lateral deviation below direction.This " direction usually " is the direction that can implement heating/refrigeration effectively.
In step 2, if judge that will make left and right sides wind direction board 9 was the width (step S5) at center towards the pointing direction with radiation temperature transducer 5 when room temperature reached design temperature.Just the pointing direction with radiation temperature transducer 5 is the center, makes left side wind direction board 91 towards the transverse direction of taking back, and makes right side wind direction board 9r towards the transverse direction that takes over.Its objective is,, promptly fully warm/when cooling off, allow wind direction, can avoid because of excessively the hot/cold wind being caused making us feeling under the weather to human body towards nobody's place when room temperature reaches design temperature.
Next step verifies surface temperature according to the signal that radiation temperature transducer sends, and judges whether this temperature is low to making us the sort of degree (step S6) of feeling under the weather.
Take this step to be because consider, it is discrepant that distance has the temperature of near position, people's ground and the indoor temperature that indoor unit 1 is judged, when particularly using the electric heating carpet in the winter time, the surface temperature of electric heating carpet is very big to people's comfort influence, so surface temperature is also taken into account whether to judge comfortable.Specifically, for making this judgement, can give comfort (for example hotness and creeping chill all are zero) by test understanding which type of surface temperature for room temperature in advance, if detected surface temperature is lower than the resulting surface temperature that can give comfort of above-mentioned result of the test, just make the judgement of " being (Yes) " so at step S6.
In step S6,, then look surface temperature for suitably entering step S4, just up-down wind direction board 7 is towards common direction if judged result is " not (No) ".On the other hand, when the judged result of step S6 is Yes, then owing to surface temperature is crossed the low up-down wind direction board 7 that makes towards the direction of heating earthward (step S7).
Here so-called " direction of heating earthward " with reference to Fig. 4, is meant direction 1. among Fig. 4 when heating, promptly under direction; When refrigeration, be meant direction 6., i.e. horizontal direction among Fig. 4.
As mentioned above, in the present embodiment, before room temperature reaches design temperature, wind direction all is to improve heating or the cooling effect to the people towards the direction that the people is arranged, after room temperature reached design temperature, wind direction just towards unmanned direction, made us feeling overheated or cold excessively with unlikely; Meanwhile, also considered the temperature on ground, low excessively as this surface temperature, will adjust wind direction with the ground of heating.So just can be than gave bigger comfort in the past.
In sum, according to the present invention, because the pointing direction of radiation temperature transducer that is used to measure surface temperature is as the directional reference that determines wind direction, therefore, can be than controlled wind direction more exactly in the past towards the direction that the people is arranged or towards unmanned direction, simultaneously, owing to be along with the surface temperature that radiation temperature transducer records is adjusted wind direction, so the comfort level that the people is experienced improves more.
