[0009]

(Embodiment 1) The structure of an air conditioner according to Embodiment 1 of the present invention will be described with reference to FIGS.

FIG. 1 shows objects to be dried 1, 2, such as laundry.
1 shows an example in which an air conditioner (in this case, a dehumidifier) 5 is disposed in a room 4 where the 3 is suspended.
Is configured to be able to change the blowing direction of the dehumidified air from "front blowing" to "oblique blowing" behind.

FIG. 2 is a schematic diagram illustrating the structure of the dehumidifier 5. The inside of the housing 10 of the dehumidifier 5 is vertically divided into two parts by a drain pan 11 or the like. In the lower space, a drain tank 12 for receiving drain from a drain pan 11, a compressor 13, and the like are stored. In the upper space, an evaporator 14, a condenser 15, a blower fan 16 having a motor 16a, and the like are housed.
In the dehumidifier 5, a compressor 13, a condenser 15, an expansion device (not shown), and an evaporator 14 are sequentially connected to form a refrigeration cycle.

A filter 1 is provided on the upper rear surface of the housing 10.
The front louver 19, the central louver 20,
An outlet 2 provided with an outlet louver 22 comprising a rear louver 21
3 are formed. In addition, an operation unit having an operation switch, a mode changeover switch, and the like, and a display unit 25 for displaying temperature, humidity, time until drying, and the like during operation are provided above the front surface of the housing 10.

Therefore, by driving the blower fan 16, room air is sucked into the machine through the air inlet 18 and the filter 17. The drawn indoor air is supplied to the evaporator 14.
The air is cooled and dehumidified in the condenser 15, reheated in the condenser 15, and blown out from the outlet 23 as so-called dehumidified air (dehumidified air).

The front louver 19, the center louver 20, and the rear louver 21 are configured so as to be adjustable in any blowing direction by a stepping motor (not shown), and the louvers 19, 20, and 21 cooperate to blow out. The blowing direction as the louver 22 is determined. FIG. 2 shows a state in which the air outlet 23 is fully closed.
An example in which the blowout louvers 22 have different blowout directions is shown in FIG. That is, FIG. 3 shows a state of front blowing, FIG. 4 shows a state of upper blowing, and FIG. Thus, the blowing direction of the dehumidified air is determined by the blowing louver 2.
2 is set according to the blowing direction of the blowout louver 22.
Is not limited to these three modes.
By controlling a stepping motor (not shown) that drives the blow-out louver 22, it can be moved at arbitrary angular intervals and set at an arbitrary angular position.

Next, the configuration of the control system according to the first embodiment will be described with reference to the block diagram of FIG. In FIG.
31 is an indoor humidity detector for detecting indoor air humidity H, 32
Is an indoor temperature detector for detecting the indoor air temperature Ta,
These are attached to the intake port 18 (not shown). Reference numeral 33 denotes a radiation temperature measuring device for measuring the temperature Tb of a drying target such as laundry at a remote position. In addition, this radiation temperature measuring device 33 has its radiation direction,
That is, it is attached to the blowout louver 22 so that the measurement direction changes in conjunction with the blowout direction of the blowout louver 22. For example, it is fixed to a side surface of the central louver 20, though not shown. Reference numeral 34 denotes louvers 19, 20, 21.
Is a louver position detector for detecting a blowing direction of the louver.

In FIG. 6, reference numeral 35 denotes a wetness calculating unit for calculating the wetness of the object to be dried, 36 denotes a louver wind direction setting unit, and 37 denotes an operation control unit. The temperature Tb of the object to be dried is lower than the indoor air temperature Ta due to heat of vaporization when the object to be dried is wet, and becomes substantially the same as the indoor air temperature Ta when the object to be dried is dry. In addition, a constant correlation is obtained between the temperature Tb of the drying target and the drying state of the drying target using the indoor air humidity H and the indoor air temperature Ta as parameters based on the amount of vaporization heat at this time.

Therefore, the wetness W of the object to be dried is set to 10, for example, the state of the laundry immediately after washing is set to 1, the state of the laundry being substantially dried is set to 1, and furthermore, the interval of the laundry to be dried is included. If the scale is set so as to be substantially proportional to the amount of water, a certain correlation can be obtained between the temperature Tb of the drying target and the wetness W of the drying target.

The wetness calculating section 35 stores data obtained by calculating or experimenting such a correlation in a memory. The data is used for the indoor air humidity H and the indoor air humidity H detected by the indoor humidity detector 31. The wetness W of the drying target is calculated by applying the indoor air temperature Ta detected by the indoor temperature detector 32 and the temperature Tb of the drying target detected by the radiation temperature measuring device 33. .

The louver wind direction setting unit 36 is provided for the blowout louver 22.
The temperature Tb of the object to be dried is measured by the radiation temperature measuring device 33 while changing the blowing direction of the object by a constant angle, the temperature Tb of all the objects to be dried is measured, and then the temperature of the object to be dried at the lowest temperature is measured. The blow direction of the louver 22 is stored, and this blow direction is set as the blow direction of the blow louver 22. Note that the blowing direction of the blowing louver 22 at this time is measured by the louver position detector 34.

The operation control unit 37 includes a louver wind direction setting unit 36.
, And the compressor 13 and the blower fan 16 are driven until the wetness W calculated by the wetness calculator 35 becomes equal to or less than the set value. Further, the display unit is controlled so as to display the wetness W of the drying target and the blowing direction of the blowing louver 22.

Next, this operation will be described with reference to the flowchart of FIG. In step S1, the blower fan 16 and the compressor 13 are driven to operate the dehumidifier 5 in a dehumidifying operation. Next, in step S2, the indoor air temperature Ta and the indoor air humidity H are detected, and in step S3, the blowout louver 22 is set to the initial position where the sweep is performed stepwise. In this specification, the blowout louver 2 is provided at an appropriate angle from the position of the front blowout to the position of the oblique blowout to the rear side in FIG.
2 is referred to as a step-wise sweep, and moving the outlet louver 22 for the step-wise sweep in this manner is simply referred to as a sweep, and further, each fixed when the outlet louver 22 is swept. The position is called a sweep position.

In step S4, the radiation temperature measuring device 33 measures the temperature of the object to be dried in the blowing direction of the blowing louver 22. Note that when there is no drying target in this measurement direction (for example, when the blowout louver 22 is swept at a position between the front blowout and the top blowout in FIG. 1).
In the measurement, the temperature of the wall surface in this direction is measured, but a temperature higher than the temperature Tb of the normal drying target is measured. Also,
In this case, the measured temperature of the wall surface is affected by the temperature of the outdoor air due to heat conduction, but is substantially the same as the indoor air temperature Ta. However, in the case of front blowing or top blowing in FIG. 1, since the drying target 1 or 2 exists in this direction,
As long as the drying target 1 or 2 is wet, a temperature Tb lower than the temperature of the wall surface is measured.

Next, in the louver wind direction setting unit 36,
The temperature Tb of the object to be dried measured in step S4 is compared with the lowest temperature of the temperature Tb of the object to be dried already measured (step S5). If the temperature is low, the temperature Tb is stored in the louver wind direction setting unit 36 in step S6 instead of the already stored minimum temperature of the drying target. Also, the blowout louver 22 at this time
Is stored in the louver wind direction setting unit 36. In step S6, the temperature detected in step S4 (the temperature of the drying target 1 in this embodiment) only when the blowout louver 22 is at the first sweep position.
Tb is stored as the minimum temperature Tb, and the first sweep position (front blowing in FIG. 1) is stored as the blowing direction at that time.

Next, in step S7, the operation control unit 37
, The blow direction of the blow-out louver 22 is set to the next sweep position, and it is determined in step S8 whether or not the sweep has been completed. If not, the process returns to step S4 and returns to step S4. Step S7 is repeated. Therefore, if step S4 is measured at the first sweep position, then in step S7, the air is blown to the second sweep position (for example, an intermediate position between the front blow and the upper blow in FIG. 1) at an appropriate angular interval. The blowing direction of the louver 22 is set. In this way, the sweep is completed when the sweep position reaches the position in the oblique direction on the back side. When the sweep is completed, the process proceeds to step S9.

In step S9, the indoor air humidity H detected by the indoor humidity detector 31, the indoor air temperature Ta detected by the indoor temperature detector 32, and the louver wind direction setting unit 3 are set.
The minimum temperature Tb of the object to be dried stored in 6 is input to the wetness calculating section 35, and from the temperatures Ta, Tb and the humidity H, the minimum temperature Tb of the object to be dried is measured for the object to be dried. The wetness W is calculated by calculation. Then, in step S10, it is determined whether or not the wetness W is equal to or less than a set value (in the above case, for example, it is assumed to be substantially dry 1.1). In the case of NO, it is determined that
The blowing direction of the blowing louver 22 is set to the direction stored in step S6 (step S11). Therefore,
Dehumidified air is supplied centering on the wet object to be dried. Then, the blowing direction and wetness W at this time are displayed on the display unit 25 (step S12), and after a predetermined time has elapsed (step S13), the process returns to step S2 and repeats the above steps. On the other hand, in step S10, YE
If it is determined as S, the drying target is dry, and the dehumidifying operation is stopped (step S14).

As described above, according to the dehumidifier as the air conditioner having the dehumidifying operation function according to the first embodiment, the drying target having the lowest temperature is specified at regular intervals, and the drying target is mainly used. Since the dehumidified air is blown out, the object to be dried is efficiently dried, thereby improving the energy efficiency and shortening the drying time. Further, the wetness of the object to be dried is calculated based on the minimum temperature, and if the wetness is equal to or less than the set value, it is determined that the drying is completed. Therefore, unnecessary dehumidifying operation is eliminated. In addition, since such a minimum temperature and wetness are measured and calculated at regular intervals,
The measurement and calculation accuracy is improved as the drying state progresses. Further, since the temperature of each of the drying objects 1, 2, and 3 is measured by a radiation temperature measuring device attached to the blowout louver 22 of the dehumidifier, the handling is simple.

Further, the blowing direction of the blowing louver 22 or /
And the wetness of the wettest drying object in the blowing direction is displayed on the display unit 25 and transmitted to the user, so that the user exchanges the position of the drying object based on this information to further improve the wetness. It can be devised so as to increase the drying efficiency. For example, in the example of FIG. 1, the upper drying object 2 is the wettest, and then the drying object 1 suspended forward is wet, and the drying object 1 suspended obliquely upward on the rear side of the dehumidifier 5. When the target 3 is almost dry, the drying target 1 in front of the dehumidifier 5 and the drying target 3 in the upper rear side are replaced. By doing so, the dehumidifier 5 is in the state of upper blowing, and the air is sucked in from the back of the dehumidifier 5. Therefore, by moving the objects to be dried 1 and 3 in this way, the efficiency of drying the objects to be dried can be further improved.

(Embodiment 2) Next, Embodiment 2 will be described with reference to FIGS. In these drawings, parts common to the first embodiment are denoted by the same reference numerals, and description thereof will be simplified.

The dehumidifier as an air conditioner according to the second embodiment has a dehumidifier 5 (see FIG. 1) disposed in a room in which laundry to be dried is suspended as in the first embodiment. ). The structure of the dehumidifier 5 is basically the same as that of the first embodiment shown in FIG.
The overlapping description is omitted. In addition, in the second embodiment,
Instead of extracting the moistest drying object as in the first embodiment and blowing out dehumidified air in the direction, the blowout louver 22 is swung with a constant swing width during a steady dehumidifying operation. The drying time is calculated from the wettest drying object and displayed.

This will be specifically described below. FIG. 8 is a block diagram showing a main part of the control system according to the second embodiment. In this block diagram, the indoor humidity detector 3
1. The indoor temperature detector 32, the radiation temperature measuring device 33, the blowout louver 22, the compressor 13, and the blower fan 16 are the same as those in the first embodiment.

The wetness calculating section 40 calculates the measured temperature of each drying object based on the indoor air temperature Ta, the indoor air humidity H and the temperature Tb of each drying object detected or measured at regular intervals. The minimum temperature Tb of Tb is determined, and the wetness W of the drying target set to the minimum temperature Tb is calculated. The method of calculating the wetness W is the same as that of the wetness calculator 35 according to the first embodiment.

The operation control unit 41 determines the time required for drying or / and the scheduled operation end time based on changes in the indoor air temperature Ta, the indoor air humidity H and the wetness W of each drying object before and after the predetermined time. And the blowout louver 22 is controlled to swing within a certain range during the certain time, that is, the blowout direction of the blowout louver 22 is controlled to swing in a certain angle range.

The display unit 43 is mounted above the front surface of the housing 10 in the same manner as in the first embodiment, but the displayed content is the remaining time required for drying or the scheduled completion time of drying. Different from the first embodiment. However, the mechanical structure of the display unit 43 may be the same as that of the first embodiment.

FIG. 9 is a flowchart of the control system according to the second embodiment. In FIG. 9, steps S1 to S9 are different only in that step S6 and step S21 in FIG. That is, in the first embodiment, step S6
In the above, the louver wind direction setting unit 36 stores the blowing direction of the blow-out louver 22 and the temperature Tb of the drying target, but in step S21 in the second embodiment, the wetness calculating unit 40 determines the minimum of the drying target. Only the temperature Tb is stored. Therefore, in FIG. 9 according to the second embodiment, in step S4 to step S8, the blowing louver 22 is swept to determine the lowest temperature Tb of the object to be dried by the radiation temperature measuring device 3.
Measure according to 3. In step S9, the wetness degree calculation unit 40 calculates the wetness degree W of the object to be dried which is the wettest based on the minimum temperature Tb. The wetness W is measured at regular intervals after step S25 as described later.

Therefore, in step S22, the operation control unit 41 determines the degree of progress of drying from the difference between the wetness W at the previous measurement and the wetness W at the current measurement, and based on this degree of progress, determines the degree of drying. And the drying end time are estimated. Then, the process proceeds to step S23, and based on the command from the operation control unit 41, these times are displayed on the display unit 43. Then, the process proceeds to step S24 to move the blowout louver 22 to a predetermined range, that is, in this case, Blow-out louver 2 within the range of blow-out diagonally upward from the back
Swing 2. The above display method is shown in FIG.
As shown in FIG. 11, the drying is performed based on the remaining time of the scheduled drying time or / and the scheduled drying time.

Then, after waiting for a predetermined time, for example, 5 to 10 minutes (step S25), the process returns to step S2, and the above-described measurement is repeated. Therefore, at regular intervals,
The above-mentioned wetness W is recalculated, and based on the recalculated wetness W, the time required for drying and the estimated end time are corrected and displayed again. When the difference between the wetness measured in the previous measurement and the wetness measured in the current measurement becomes 0 in step S22, all the objects to be dried are dried, and the remaining time in step S23 at this time is determined. Is displayed as 0.

As described above, according to the air conditioner having the dehumidifying operation function (the dehumidifier 5) of the second embodiment, the wetness of the object to be dried which is the wettest is measured at regular time intervals, and is required for drying. The remaining time and the drying end time are displayed to inform the user. Therefore, in the conventional case, the drying time cannot be predicted, and a wasteful operation of continuously operating the dehumidifier even after the drying target is dried is performed. However, according to the second embodiment, Such useless operation can be avoided, and the dehumidifying operation efficiency can be improved. Also, knowing the drying end time allows the user to act systematically, which is convenient.

Third Embodiment Next, a third embodiment will be described with reference to FIGS. Note that the same reference numerals are given to portions common to those in the first embodiment, and description thereof will be simplified.

The dehumidifier according to the third embodiment is a dehumidifier 5 (see FIG. 1) arranged in a room where laundry is suspended as an object to be dried as in the first embodiment. The structure of the dehumidifier 5 is basically the same as that of the first embodiment shown in FIG. 2, but the dehumidifier 5 of the third embodiment measures the radiation temperature in the first embodiment. Table 33
Not equipped. Instead, as shown in FIG. 12, as a means for detecting the water content Sw of the object to be dried, a water content detection element 51 having a transmission unit is attached to each of the objects to be dried 1, 2, and 3. . Further, the dehumidifier 5 is provided with a unit for receiving a transmission from the water content detection element 51.

The third embodiment is different from the first embodiment.
Instead of extracting the humid object to be dried as described above, and simply blowing out dehumidified air in that direction, a blow direction in which a large dehumidifying effect is obtained is detected, and the blow louver 2 is detected in that direction.
By controlling the blowing direction of No. 2, a more efficient dehumidifying operation is enabled. This direction may be fixed to a fixed blowing direction as described later, or may be a direction in which the swing range is determined by an appropriate method.

Hereinafter, this control will be described in detail. FIG.
FIG. 9 is a block diagram showing a main part of a control system according to Embodiment 3. In this block diagram, reference numeral 51 denotes a moisture content detection element for the object to be dried; 52, a louver wind direction setting unit; and 53, an operation control unit.

The water content detection element 51 applies a weak current to the object to be dried, detects the water content Sw of the object to be dried based on the resistance value, and separates the detected water content Sw as a water content signal (this embodiment). In the third embodiment, there is provided a transmitting means for transmitting to a receiving means provided in the dehumidifier 5). In addition, such a water content detection element 51 may be a known element described in, for example, JP-A-8-200755. The water content Sw is, for example, similar to the wetness W in the first embodiment, for example, the water content S of the laundry immediately after washing.
The w is set to 10, the dried state is set to 1, and the scale is set so as to be substantially proportional to the water content of the laundry to be dried.

The louver wind direction setting section 52 outputs an output signal for moving the blowing direction of the blow-out louver 22 by a predetermined angle and stopping at each moving position for a predetermined time to an operation control section 53 to be described later. During the time, a water content signal is received from the water content detection element 51 attached to each of the drying objects 1, 2, and 3, and the drying object having the maximum water content Sw among the water contents Sw of each drying object is determined. Detecting and calculating the water content change amount ΔSw of the drying object having the maximum water content Sw, and outputting the output signal for setting the blowing direction of the blowout louver in a direction in which the water content change amount ΔSw is determined to be large. This is output to the operation control unit 53.

The operation control unit 53 performs the dehumidifying operation while setting the blow direction of the blow louver 22 based on the output signal from the louver wind direction setting unit 52, and resets the blow direction of the blow louver every predetermined time. Dehumidifier 5
It controls the operation of.

Next, the operation of the control system will be described with reference to the flowchart of FIG. First, step S31
To drive the compressor 13 and the blowing fan 16 to perform the dehumidifying operation. Next, in step S32, the initial sweep position is set. Then, in step S33, the water content Sw of each of the drying objects 1, 2, and 3 is detected by the water content detection element 51 attached to each of the drying objects 1, 2, and 3.
This water content Sw is used as a water content signal as the water content detection element 51.
The dehumidifier 5 as a component device of the louver wind direction setting unit 52
It is transmitted to the receiving means provided in the main body. The louver wind direction setting unit 52 detects the drying target having the maximum water content Sw among the water content Sw of the drying targets 1, 2, and 3 based on the received water content signal (step S3).
4). Next, the maximum water content Sw is compared with the already detected maximum water content Sw (step S35), and if it is larger, the maximum water content Sw is stored (step S35).
36). In step S36, only when the blowout louver 22 is at the first sweep position, the water content Sw detected in step S34 is used as the maximum water content S
stored as w.

In the louver wind direction setting section 52,
The water content Sw of the drying object having the maximum water content Sw after the blowing louver 22 is fixed for a predetermined time is received, and the water content change amount ΔSw of the drying object having the maximum water content Sw within the predetermined time is received. Is detected (step S3).
7). Then, the water content change amount ΔSw is compared with the stored water content change amount ΔSw (step S3).
8) If it is larger, the water content change amount ΔSw at that time and the blowing direction of the blowing louver 22 are stored (step S3).
9), advance the blowing louver to the next sweep position (step S40). In step S39, the water content change amount ΔSw detected in step S37 only when the blowing direction of the blowing louver 22 is at the first sweep position.
Is stored as it is.

Next, it is confirmed that the sweep is not completed (step S41), and steps S33 to S40 are repeated until the sweep of the blowout louver 22 is completed. Therefore, when the sweep is completed, the blowing direction of the blowing louver 22 stored in step S39 is determined to be the direction in which the water content change amount ΔSw increases.

In step S42, the blowing direction of the blowing louver 22 is set based on the above determination result, and the result is output from the louver wind direction setting unit 52 to the operation control unit 53.
Then, the operation control unit 53 controls the blowing direction of the blow-out louver 22 based on the output signal from the louver wind direction setting unit 52, performs a dehumidifying operation for a certain time, returns to step 32 after a certain time has elapsed, and returns to step 32. Control is performed to reset the setting of the blowing direction. Thus, in the dehumidifier of the third embodiment, the blowing direction of the blowing louver 22 is set at regular intervals.

The setting of the blowing direction of the blowing louver 22 may be performed by fixing the blowing direction of the blowing louver 22 to the direction stored in step 39.
Is often dispersed in a certain range without concentrating in a certain direction, so that it is generally preferable to swing a predetermined angle around the direction stored in step 39.

As described above, according to the air conditioner (dehumidifier 5) having a dehumidifying function described in the third embodiment, the moisture content detecting element 51 is provided for each object to be dried, and the drying target is provided at regular intervals. The dehumidifying operation is performed while checking the water content change amount ΔSw and judging the optimum blowing direction of the blowing louver 22 each time, so that an efficient dehumidifying operation can be performed.

In the third embodiment, the center of the blowing direction of the blow-out louver 22 is determined. It is also possible to grasp the amount ΔSw, obtain a range in the blowing direction in which the water content change amount ΔSw exceeds an appropriate threshold value, and swing the blowing louver 22 within this range.

As described above, the present invention has the following advantages. According to the first aspect of the present invention, a drying target having the lowest temperature is specified, and dehumidified air is blown around the drying target, so that the drying target is dried efficiently, and energy efficiency is improved and drying is performed. Time can be reduced. Further, the wetness of the object to be dried is calculated based on the minimum temperature, and if the wetness is equal to or less than the set value, it is determined that the drying is completed. Therefore, unnecessary dehumidifying operation is eliminated.
