Detailed description of the invention

Hereinafter, with reference to the accompanying drawings of embodiments of the present invention.

Fig. 1 is the stereoscopic figure of the air conditioner representing embodiment.Fig. 2 is the Sketch figure of the inside of the air conditioner representing embodiment.Fig. 3 is the summary stereogram that the wind direction of enlarged drawing 1 represents with changing component.Fig. 4 is the schematic diagram of the detection range of the infrared ray sensor of the air conditioner representing embodiment.

As shown in Figure 1, the air conditioner of present embodiment is formed by with lower component: the air conditioner framework 100 that can be formed independently; For room air A being taken into the suction inlet 101 in air conditioner framework 100; Storage tank 102, stores from being taken into the moisture eliminated the air of suction inlet 101; And will the dry air B of moisture be eliminated from air conditioner framework 100 to the exhaust outlet 103 of indoor discharge.

Exhaust outlet 103 is provided with the variable component 1 of the wind direction making the wind direction of dry air B variable.The variable component of this wind direction 1 is by making the variable longitudinal direction of the wind direction of vertical direction put leaf 1a and make the variable transverse direction of the wind direction of horizontal direction put leaf 1b to form.

In addition, storage tank 102 can be installed in air conditioner framework 100 removably.

Below, as shown in Figure 2, have in the inside of air conditioner framework 100: Air Blast fan 2, produce and suck room air A from suction inlet 101 and discharge the so a series of air-flow of dry air B from exhaust outlet 103; Fan electromotor 2a, makes Air Blast fan 2 rotate; Temperature sensor 3(temperature detecting member), detect the temperature of the room air A be attracted from suction inlet 101; Humidity sensor 4(Humidity Detection component), detect the humidity of room air A; Dehumidifying component 5, the moisture contained by removing room air A also generates dry air B; Longitudinally variable motor 1c, makes longitudinally pendulum leaf 1a variable along vertical direction; Transverse variable motor 1d, makes laterally pendulum leaf 1b variable in the horizontal direction; As the infrared ray sensor 6 of surface temperature detection means; Show the display part (not shown) of various information; And control circuit 7(control member).

These various sensors are connected to control circuit 7, so that its detection signal can input to control circuit 7.In addition, dehumidifying component 5, display part, various motor are connected to control circuit 7, so as can to input based on the operation of user, the input value of various sensor controlled by control member.

Secondly, dehumidifying component 5 can remove moisture in air and condensation, such as, as the most general component can adopt form heat pump circuit and in evaporimeter, make the mode of the condensate moisture in air, make the air that removed by adsorbent in the drier mode etc. of moisture condensation in heat exchanger.

And, be stored in storage tank 102 by dehumidifying component 5 moisture that air A is removed indoor as condensed water C.

Below, as shown in Figure 3, longitudinally pendulum leaf 1a has the rectangular opening that the width along air conditioner framework 100 extends, roughly using the rotating shaft of variable for above-mentioned longitudinal direction motor 1c as axle, can form changeably along vertical direction.

Laterally pendulum leaf 1b is configured to be configured at equal intervals and longitudinally puts in leaf 1a, can be bearing in the inboard of the opposition side of the opening of longitudinally pendulum leaf 1a in the horizontal direction changeably, carry out interlock with the driving of above-mentioned transverse variable motor 1d by axle.

Infrared ray sensor 6 is installed in the one side of transverse direction pendulum leaf 1b of the substantial middle be configured in longitudinal pendulum leaf 1a.

Thus, the direction of the dry air B that the detection range of the surface temperature of infrared ray sensor 6 pairs of dried object etc. is variable with passing through the variable component of wind direction 1 is roughly the same.That is, infrared ray sensor 6 can detect the surface temperature in the whole region in scope that the variable component of wind direction 1 can blow.

Secondly, infrared ray sensor 6 adopts the sensor that such as make use of thermo-electromotive force effect, is made up of (with reference to Fig. 2, Fig. 3) the thermistor 6b of the temperature of the infrared absorbing film 6a and detection infrared absorbing film 6a that receive the heat radiation (infrared ray) sent from the surface in regulation region.

This infrared ray sensor 6 by the temperature (hot junction) of the sensible heat part of the infrared absorbing film 6a heated up by absorptive thermal radiation, convert the signal of telecommunication of voltage etc. to the difference of the temperature (cold junction) of the infrared absorbing film 6a detected by thermistor 6b, and inputs control circuit 7 described later.The surface temperature in regulation region can be differentiated according to the size of this signal of telecommunication.

Here, about the detection method of the surface temperature in regulation region, use Fig. 4 to be described.As shown in Figure 4, when the whole region can detected by infrared ray sensor 6 is as full scan scope 200, full scan scope 200 becomes the scope of the planar expanded to transverse direction (horizontal direction), longitudinally (vertical direction).

This infrared ray sensor 6 is controlled so as to, for full scan scope 200 being divided into each detection surface temperature in multiple cut zone 201 with vertical direction in the horizontal direction.Thereby, it is possible to be made detailed temperature map figure for the region of wide region.

Secondly, when above-mentioned control circuit 7 detect have selected dehumidification mode from the switching manipulation of operating portion (not shown), drive the variable component 1 of wind direction and can blow from exhaust outlet 103, drive fan motor 2a makes Air Blast fan 2 rotate, drive dehumidifying component 5, become optimum humidity to make indoor humidity.

In addition, control circuit 7 drives the variable motor 1c of the longitudinal direction of the variable component of wind direction 1 and transverse variable motor 1d, blows with the direction in region desired by indoor.Thus, room air A is taken in air conditioner framework 100 from suction inlet 101, after the temperature and humidity in temperature sensor 3 and humidity sensor 4 difference sensing chamber, dehumidified by dehumidifying component 5 and become dry air B, from exhaust outlet 103 to indoor blowout.

In addition, when control circuit 7 detects that the running of the drying mode of dried object and washings starts, drive the variable component 1 of wind direction as described above and can blow from exhaust outlet 103, drive fan motor 2a makes Air Blast fan 2 rotate, and drives dehumidifying component 5.

Then, control circuit 7 reads in indoor humidity by humidity sensor 4 from the room air A be taken in air conditioner framework 100, judges that whether this humidity is higher than specified humidity.

Control circuit 7, when the humidity ratio specified humidity height of indoor, controls fan electromotor 2a and the variable component 1 of wind direction, becomes maximum, until the humidity of indoor reaches specified humidity to make the dehumidifying effect of dehumidifying component 5.

And, control circuit 7 is when making indoor humidity be reduced to specified humidity by this control, the configuration scope of infrared ray sensor 6 pairs of washings is used to determine, the mode arriving this scope with dry air B controls longitudinally variable motor 1c and transverse variable motor 1d, makes each pendulum leaf 1a, 1b towards the direction of washings.Specified humidity is in advance according to the humidity that the temperature of indoor sets, and is set in control circuit 7 as data.

Below, for the work of the control circuit 7 when have selected so-called " the energy-conservation airing pattern of cloth drying " and each several part, use Fig. 5 to be described, so-called " the energy-conservation airing pattern of cloth drying " environmentally the testing result of condition combines dehumidifying running and the drying of dried object is carried out in the air-supply running of only blowing.

The flow chart of work when Fig. 5 is the drying mode of the air conditioner representing embodiment.In addition, about the work of " common dehumidifying running ", because illustrating above, so omit.

The control circuit 7 of air conditioner detects and have selected the energy-conservation airing pattern of cloth drying, when starting running, start the mensuration (S0) of the total run time T1 from running, and drive the variable component 1 of wind direction and can blow from exhaust outlet 103, drive fan motor 2a also makes Air Blast fan 2 rotate and putting in blast (S1).In addition, in this stage, dehumidifying running is not carried out.

Now, wet clothing receives blows and moisture vaporization, and temperature becomes lower than the temperature of surrounding.Detect the low position of this temperature by infrared ray sensor 6, control circuit 7 detects the scope (S2) residing for dried object and clothing thus.

Then, the temperature RT of mensuration room air A and the operation of humidity RH1 is entered.

First, control circuit 7 starts the stipulated time A(binding hours for detected temperatures RT and humidity RH1) timer (S3) measured.And, for the room air A being inhaled into air conditioner framework 100 inside by Air Blast fan 2 from suction inlet 101, by temperature sensor 3 and humidity sensor 4 detected temperatures RT and humidity RH1(S4 respectively).

Stipulated time A becomes the fiducial time for determining air-supply time Ts, this air-supply time Ts such as by add damp condition, temperature conditions for determining that the calculating of air-supply time obtained.

Then, control circuit 7 reads in the humidity RH1 of the room air A detected, and compares with specified humidity.When specified humidity such as refers to and the humidity of more than 80% high state detected.

When humidity RH1 is lower than specified humidity, divide a word with a hyphen at the end of a line to S6, when humidity RH1 is higher than the humidity of regulation, divide a word with a hyphen at the end of a line to S11, and start dehumidifying running (S5).

Then, control circuit 7 reads in the temperature RT of the room air A detected, and compares with set point of temperature.

When set point of temperature such as refers to the state detecting and become less than 15 DEG C.

When temperature RT is higher than set point of temperature, divide a word with a hyphen at the end of a line to S7, when temperature RT is lower than the temperature of regulation, divide a word with a hyphen at the end of a line to S11, and start dehumidifying running (S6).

The state of room air A dividing a word with a hyphen at the end of a line from this S6 to S7 is the state of relatively low humidity high-temperature, thus can be described as the easily dry state of wet clothing.

In addition, the state of dividing a word with a hyphen at the end of a line to S11 in S5 and S6 is condition that can not be fully dry under air-supply.That is, be following judgement, that is, do not carry out air-supply running, divide a word with a hyphen at the end of a line directly to dehumidifying running, carry out controlling so that dried object can not become not dry.

Then, control circuit 7 when humidity RH1 than specified humidity low and temperature RT is higher than set point of temperature, perform the control of the maximum RHM of the humidity detected in stipulated time A, and divide a word with a hyphen at the end of a line (S7) to S8.And control circuit 7, when the maximum RHM of the humidity in stipulated time A being detected, is divided a word with a hyphen at the end of a line to S9, when the maximum RHM of humidity not detected, divide a word with a hyphen at the end of a line (S8) to S3.

Here, the detection method of the maximum RHM of humidity also can be in the humidity RH1 that detects in stipulated time A, using the maximum RHM of maximum humidity as humidity, in addition, also can using humidity RH1 from the humidity RHM risen when turning to decline as the maximum RHM of humidity.

Then, control circuit 7, based on the maximum RHM of the humidity detected, carries out the calculating of remaining air-supply time Ts, and divides a word with a hyphen at the end of a line (S9) to S10.Here, the maximum RHM of humidity is larger, and air-supply time Ts is set longer.Thus, even if humidity is high, also can shortens the time of dehumidifying running, more energy-conservation effect can be obtained.

And control circuit 7, during the remaining air-supply time Ts set as described above, after continuing air-supply running, is divided a word with a hyphen at the end of a line to S11, and the running (S10) that end is only blown.

Then, control circuit 7 starts dehumidifying running and divides a word with a hyphen at the end of a line to S12, Air Blast fan 2 and dehumidifying component 5 is worked, and starts the measurement of the dehumidifying T2 duration of runs from dehumidifying running, and divide a word with a hyphen at the end of a line (S12) to S13.

Thus, by the rotation of Air Blast fan 2, room air A is taken in air conditioner framework 100 from suction inlet 101, continues blowout dry air B from exhaust outlet 103.Now, control circuit 7 reads in the temperature of the indoor detected by temperature sensor 3, and continues the humidity of reading in the indoor detected by humidity sensor 4.

Then, control circuit 7 judges whether the dehumidifying T2 duration of runs from dehumidifying running have passed through 30 minutes, when the duration of runs, T2 was more than 30 minutes in dehumidifying, divides a word with a hyphen at the end of a line (S13) to S14.

Then, control circuit 7 judges that the humidity RH1 of room air A is whether as less than 50% (S14).When the humidity RH1 of room air A is less than 50%, divide a word with a hyphen at the end of a line to S15, when the humidity RH1 of room air A is more than 50%, divide a word with a hyphen at the end of a line to S19.

And control circuit 7, in S19, judges whether the total run time T1 from running exceedes the binding hours (limit time) namely 12 hours of predetermined running.When total run time T1 is not more than 12 hours, divide a word with a hyphen at the end of a line to S14, when total run time T1 was more than 12 hours, divide a word with a hyphen at the end of a line to S21, and carry out pressure and end process.

Then, control circuit 7 calculates TL(S15 remaining time of dehumidifying running by the dehumidifying T duration of runs from dehumidifying running and room temperature RT) after, divide a word with a hyphen at the end of a line to S16, and TL remaining time is presented at display part, divide a word with a hyphen at the end of a line to S17.

Then, control circuit 7 judges that the humidity RH1 of room air A is whether as less than 50% (S17).When the humidity RH1 of room air A is less than 50%, divide a word with a hyphen at the end of a line to S18, after the dehumidifying running added, terminate running.When the humidity RH1 of room air A is more than 50%, divide a word with a hyphen at the end of a line to S20.

And control circuit 7, in S20, judges whether the total run time T1 from running exceedes the binding hours (limit time) namely 12 hours of predetermined running.When total run time T1 is no more than 12 hours, divide a word with a hyphen at the end of a line to S16, when total run time T1 was more than 12 hours, divide a word with a hyphen at the end of a line to S21, and carry out pressure and end process.

Make each several part work as described above by control circuit 7, before dehumidifying running, combine the air-supply running of only blowing operate, thus carry out the dry operating of dried object and clothing while power consumption can be suppressed.

Especially, in the testing result of environmentally condition, even if when being judged as that dried object uses the condition that air-supply also can be dry, carrying out air-supply running in the first half time of cloth drying running, operated by dehumidifying in the running later half time and complete.Thus, and operate compared with the cloth drying implemented operates by common dehumidifying, can power consumption be suppressed.

In addition, detecting temperature or the humidity of room air, be judged as by air-supply can not be dry fully condition when (S5, S6), carry out the running stopping only to blow and the control of dividing a word with a hyphen at the end of a line to dehumidifying running, thus no matter environmental condition is how, can both at the end of running, make dried object dry, so that dried object can be dry.

In addition, owing to determining the time of air-supply running based on the humidity of room air, thus the air blowing control of the excellent in efficiency of the humidity conditions being suitable for room air can be carried out.

The numerical value controlling benchmark that becomes used in above embodiment is only an example, the invention is not restricted to above-mentioned numerical value.In addition, these numerical value becoming benchmark also suitably can set change according to the use environment of air conditioner, the hobby of user.
