The temperature distribution subdivided by the means is recognized and recorded and held, and the comparing means 20 is the temperature and temperature of the object to be dried recorded and held by the object temperature distribution determining means 19. Detecting means 7, comparing determines the ambient temperature detection results obtained from the temperature determining means 14, is to record keeping the difference between the temperature and the ambient temperature of the material to be dried. As an embodiment, as shown in FIG. 3, the infrared detection means 9a, 9b, 9c, 9d, 9e, 9f, 9g, and 9h are configured as a unit, and the arrangement of objects to be dried is assumed on the infrared detection surface. Infrared detection means 9 housed in a case 20 having a detection surface formed by an optical filter 19 whose focal range is matched to detection of infrared rays emitted from the upper 1.5 m to 2.0 m of the main body is used. Each of the infrared detection means 9a, 9b, 9c, 9d, 9e, 9f, 9g, 9h has directivity and each detection range is 9a ′, 9b ′, 9c ′, 9d ′, 9e ′, 9f ′, 9g ′. , 9h ′.

  Further, as an embodiment, as shown in FIG. 4, the rotation movable range of the stepping motor 10 in which the infrared detecting means 9 is fixedly arranged is configured to be 120 °. The stepping motor control means 16 stops at the angular positions P1, P2, P3, P4, P5, P6, P7, P8, P9 defined every 15 ° with the stepping motor rotation axis as the center, and the infrared detecting means 9a, 9b, 9c. , 9d, 9e, 9f, 9g, and 9h, temperature detection is performed.

  In the above configuration, the main operations related to temperature detection at each detection position will be described. As shown in the flowchart of FIG. 5, in step 1 after the temperature detection is started, the stepping motor control means 16 is inputted with numerical values from 1 to 9. The variable a is designated as (a = 1) at the designated detection position Pa using the variable a. In STEP2, the stepping motor control means 16 controls the rotational drive of the stepping motor 10, and in STEP3, it is determined whether or not the detection position Pa that has already been specified has been reached. If the designated detection position has not been reached, the process returns to STEP 2 and if it is determined that the designated detection position has been reached, the process proceeds to STEP 4 where the stepping motor 10 is stopped and the infrared detection means 9a, 9b, 9c, 9d, 9e, 9f, 9g, and 9h perform temperature detection, respectively, and the temperature detection results are held for each of the infrared detection means in the drying object temperature determination means 18a, 18b, 18c, 18d, 18e, 18f, 18g, and 18h. In STEP 5, it is determined whether the variable a is (a = 9). Here, since a = 1, the process proceeds to STEP 6 and (a + 1) is input as the variable a. Here, since a = 1, the variable a is a = 2. Next, returning to STEP2, the flow from STEP2 to STEP6 is executed. The flow from STEP2 to STEP6 is executed, the variable a is specified as a = 9, the temperature detection flow is executed at the detection position P9, and after holding, the variable a is input with a = 9 in the determination in STEP5. Therefore, the process proceeds to STEP7. At this point, the stepping motor 10 can perform temperature detection at each of the detection positions P1 to P9. Therefore, in STEP 7, the to-be-dried object temperature distribution determination means 19 detects the infrared rays at the detection positions P1 to P9 held in the to-be-dried object temperature determination means 18a, 18b, 18c, 18d, 18e, 18f, 18g, and 18h. The temperature detection results of the means 9a, 9b, 9c, 9d, 9e, 9f, 9g, and 9h are recognized and determined as the temperature distribution (P1 to P9) of the material to be dried. In FIG. 6, temperature distributions (P1 to P9) are shown as Ta1 ′ to Th8 ′ as the temperature detection results at the respective detection positions by the respective infrared detection means.

Next, the process proceeds to STEP 8, and the variable a is designated (a = 9). Thereafter, the operations in STEP9 to STEP13 are the same as those in STEP2 to STEP6. However, in STEP13, (a + 1) is input as the variable a, and in STEP12, it is determined whether the variable a is (a = 1). Do. After STEP 9 to STEP 13 are executed and temperature detection is executed when the variable a is (a = 1), the process proceeds to STEP 14 as a result of the determination in STEP 12. At this time, the stepping motor 10 can perform temperature detection at each of the detection positions P9 to P1 in the reverse direction to the rotation direction in which the temperature distribution (P1 to P9) is detected. Therefore, in STEP 7, the to-be-dried object temperature distribution determining unit 19 detects the infrared rays at the detection positions P1 to P9 held by the to-be-dried object temperature determining units 18h, 18g, 18f, 18e, 18d, 18c, 18b, and 18a. The temperature detection results of the means 9a, 9b, 9c, 9d, 9e, 9f, 9g, and 9h are recognized and determined as the temperature distribution (P9 to P1) of the material to be dried. In FIG. 7, the temperature detection results at each detection position by each infrared detection means are Ta1 ″ to Th8 ″ and the temperature distribution (P9 to P1).
Indicates.

  Next, in STEP 15, the same detection positions of the temperature distribution (P1 to P9) and the temperature distribution (P9 to P1) and the temperature distribution of the infrared detection means are averaged. In STEP 16, the averaged temperature distribution is recognized as the temperature distribution of the material to be dried. In FIG. 8, the temperature distribution (P1-P9) and the temperature distribution (P9-P1) averaged to-be-dried material temperature distribution are shown.

  As described above, by mounting a plurality of infrared detection means 9 and performing detection position control, it is possible to recognize a temperature distribution obtained by subdividing the material to be dried.

  As an example of the dehumidifying operation, when the humidity is high, for example, when the humidity is 55% RH or higher, the dehumidifying operation is strongly performed. When the temperature is high and the temperature is high, for example, at 35 ° C. or higher, the operation is performed only by blowing.The temperature decreases, for example, at 35 ° C. or lower, the dehumidifying operation is performed. If the temperature of the object to be dried is higher than the room temperature for a certain period of time, for example, 30 minutes or more, it is determined that the object to be dried has been dried, and the dehumidification operation and operation are completed, thereby saving energy and efficiently dehumidifying. It is for driving.

  Here, the specified movable range 120 ° of the stepping motor 10 coincides with the movable range of the wind direction louver 6, and the wind direction louver control means 17 has the angular positions P 1, P 2, P 3 as in the control of the stepping motor control means 16. , P4, P5, P6, P7, P8, and P9 are controlled to drive and stop the wind direction louver 6 so that the dehumidified air blowing direction controlled by the wind direction louver 6 matches the detection surface direction of the infrared detecting means 9. Thus, it is possible to recognize the change in the drying state of the object to be dried by the blowing of dehumidified air, and the background.

  Further, the temperature detection flow is executed before the operation of the dehumidifying means 2 and the air blowing means 3, whereby the temperature distribution in the initial natural drying state of the object to be dried can be recognized.

  Further, the wind direction louver control means 17 is provided at the detection positions P1, P2, P3, P4, P5, P6, P7, P8, and P9 specified when the temperature detection, to-be-dried object temperature distribution recognition flow is executed. By matching the direction in which the dehumidified air is blown out by the wind direction louver 6, the infrared detecting means 9 can detect a decrease in sensible heat due to moisture evaporation due to the blowing of the dehumidified air.

  Further, the comparison means 20 compares and determines the temperature detection results in each detection range of the object to be dried obtained by the object temperature distribution determination means 19 and the ambient temperature detection results obtained from the temperature detection means 7 and the temperature determination means 14. The portion where the detection result of each detection range temperature of the object to be dried is lower than the ambient temperature is extracted and held. The control unit 11 recognizes and determines the location of the object to be dried and the range obtained from the extracted and held results, so that the user can recognize the location of the object to be remotely placed.

  Further, the wind direction louver control means 17 drives and controls the wind direction louver 6 to control the blowing direction of the dehumidified air within the range of the object to be dried, so that the user can freely use the dehumidifier body without setting the dehumidifying air blowing direction. In addition, the dehumidified air can be blown to the object to be dried.

  Further, the wind direction louver control means 17 controls the driving of the wind direction louver 6 and designates the blowing direction of the dehumidified air in a direction different from the detection direction of the infrared detection means 9, so that the infrared detection means 9 is controlled by the dehumidification means. On the other hand, the temperature state of the object to be dried can be detected without being affected by the dehumidified air whose temperature has increased.

  In addition, when the temperature is detected by the infrared detecting means 9, the dehumidifying control means 12 stops the dehumidifying means 2 and only blows air by the blower means 3, so that the drying progresses as moisture is released from the material to be dried by blowing the dehumidified air. As a result, the amount of moisture released is reduced, the degree of sensible heat reduction of the object to be dried is reduced, and the influence of the increase in sensible heat of the object to be dried can be reduced by blowing dehumidified air higher than the ambient temperature by the dehumidifying means. Thus, it is possible to accurately detect a decrease in sensible heat due to the release of a small amount of water from the dried material that has been dried.

  Further, when the temperature is detected by the infrared detecting means 9, the dehumidifying control means 12 can stop the dehumidifying means 2, and the air blowing control means 13 can stop the air blowing means 3, so that the temperature state of the object to be dried can be detected. .

  In the dehumidifier according to the present invention, the temperature of the object to be dried is detected by detecting the infrared radiation emitted by the selected clothing assumed as the object to be dried, and the temperature state of the object to be remotely placed is contacted. By detecting with, it becomes possible to verify the degree of drying progress of the object to be dried with higher accuracy, which is useful for operation control of the dehumidifier for drying the object to be dried.
