(Embodiment 1)
FIG. 1 is a configuration diagram of a laundry drying system according to Embodiment 1 of the present invention.

  As shown in FIG. 1, a ceiling 2 of a bathroom space 1 as a room is provided with a heating air blowing unit 3 as air blowing means for heating and blowing air in the bathroom space 1. The heating air blowing unit 3 has a configuration in which an air inlet 4, an electric heater 5 as a heating means, a cross flow fan 6 as an air blowing means, and an air outlet 7 communicate with each other, and the air 8 in the bathroom space 1 from the air inlet 4. , Heated by the electric heater 5 and pressurized and blown by the cross flow fan 6, and a blown airflow 9 is blown out from the outlet 7 to the bathroom space 1.

  Further, the suction port 4 is communicated to the outdoors via a duct 11 using an exhaust fan 10 as a ventilation means, and part of the bathroom air sucked in by the suction port 4 is discharged to the outdoors as exhaust air 12. It has become. The suction port 4 is provided with a filter 13 for removing dust flowing from the bathroom space 1 together with air.

  The bathroom space 1 is provided with clothes racks 15a and 15b for hanging the laundry 14a and 14b, and an operator who hangs the laundry 14a and 14b has a strong air flow 9 from the outlet 7. The laundry 14a, 14b is suspended from the laundry baskets 15a, 15b while checking the thickness. In that case, according to the airflow distribution formed in the bathroom space 1 by the blowing airflow 9 from the blower outlet 7, the order in which the laundry 14a, 14b is hung on the clothes-drying baskets 15a, 15b is determined.

  That is, in the bathroom space 1, the laundry 14a having a high degree of difficulty in drying is used as an area where the airflow is strong, for example, as an area where the airflow 9 from the air outlet 7 directly hits. The laundry 14b having a low degree of difficulty in drying is compared and selected in an area where the blown airflow 9 is not directly applied, and is hung on the laundry baskets 15a and 15b.

  In general, the surface heat transfer coefficient is affected by the airflow around the object. Even in the case of laundry, the surface heat transfer coefficient of the laundry is similarly affected by the airflow around the laundry, so the heat flow to the laundry increases as the wind speed around the laundry increases. However, a difference occurs in the drying ability of each laundry. Therefore, the laundry with a low drying difficulty is selectively hung from the area where the airflow is weak, and the laundry with a high drying difficulty is gradually hung from the area where the airflow is strong. It will dry uniformly on average.

  Next, the difficulty of drying that needs to be taken into account when the operator hangs the clothes racks 15a and 15b will be described.

  There are various types of laundry in general households such as fiber types and cloth thicknesses, and it is clear that there are differences in the difficulty of drying depending on the laundry.

  In other words, the difficulty of drying in the laundry is defined in terms of the amount of time it takes to reach dryness for laundry exposed to a certain ambient environment. It is determined by the ratio of the rate at which moisture evaporates. In order to evaporate the moisture contained in the laundry, it is necessary to obtain the amount of heat equivalent to the latent heat of vaporization, so the rate at which the moisture contained in the laundry evaporates depends on the ambient environmental conditions such as temperature, humidity, and wind speed. It is determined. Therefore, the difficulty of drying the laundry is an index determined by the amount of moisture per unit area of the laundry.

  The worker who hangs the laundry needs to determine the difficulty of drying in each laundry during the operation of hanging the laundry. The moisture content per unit area of the laundry is influenced by the factor of the volume that can contain moisture and the factor of the moisture content per unit volume as a percentage that contains moisture. The thickness of the laundry cloth is a factor for the volume that can contain moisture, and the type of laundry material is a significant factor for the moisture content.

  In addition, since laundry at home is repeatedly performed on a daily basis, the weight of each laundry in the dry state is grasped sensuously and unconsciously. And in the operation | work which hangs laundry, the weight of each laundry can be recognized sensuously by the necessity of picking up each laundry. Therefore, it is possible to recognize the amount of water contained in the laundry by performing a relative comparison between the dry state and the wet state based on the weight information of the laundry that can be grasped sensuously in a series of washing operations.

  In this way, as a material for determining the difficulty of drying in the laundry, by comparing the thickness of the laundry fabrics that have been washed at the same time, it is possible to visually and The thickness of the fabric of each laundry is recognized based on sensory information such as the touch, and it is possible to determine the difficulty of drying the laundry without burdening additional work.

  In addition, as an index for determining the difficulty of drying in the laundry, by comparing the ratio of natural fibers as the type of laundry material that has been washed at the same time, the operator can see a specific indication of clothing quality. The numerical index will be confirmed, and the difficulty of drying the laundry can be clearly determined by comparing the numerical display.

  Also, as an index for determining the difficulty of drying in the laundry, by comparing the weight of the laundry that has been washed at the same time with the weight at the time of drying, the operator recognizes the weight as the laundry is dried. Therefore, it can be judged sensuously.

  In the above configuration, the drying ability as a difference in the convective heat transfer coefficient on the surface of the laundry based on the strength of the airflow and the order based on the difficulty of drying in the laundry are complementarily combined. By arranging according to the degree of difficulty of drying, the effect that the entire laundry can be dried on average can be obtained.

  In the first embodiment, the heating air blowing unit that heats and blows air into the indoor space is used. However, a unit that can blow air into the indoor space such as a dehumidifying air blowing unit may be used instead of the heating air blowing unit. There is no difference in effect.

  In the first embodiment, the cross flow fan is used as the air blowing means. However, a sirocco fan may be used instead of the cross flow fan, and there is no difference in the operation effect.

The clothes-drying basket 15 has a cylindrical bar shape and has no directionality with respect to the circumferential rotation direction of the cylinder. Therefore, when the clothes-drying basket 15 is supported by the receivers 17a, 17b, it is arbitrarily fixed with respect to the circumferential rotation direction of the cylinder. Will be.

  On the surface of the clothes basket 15, an indicator 18 of a drying ability that can relatively recognize the degree of drying of the laundry depending on the position of hanging on the clothes basket 15 is displayed. It can be recognized quantitatively without causing misperception due to sensory values.

  Further, the drying ability index 18 displays the drying ability as the superiority or inferior degree of drying of the laundry due to the coloring of the surface of the drying basket 15, and the difference in the drying ability with respect to the axial direction of the drying basket 15 is represented by a large or small range of coloring. It is expressed. The indicator 18 of the drying ability is colored so as to be annular with respect to the circumferential direction of the cylindrical rod shape of the clothes-drying basket 15.

  In the above configuration, the hanging basket 15 is fixed with respect to the receiving tools 17a and 17b, regardless of the direction of the hanging basket 15 with respect to the circumferential rotation direction, and an angle at which an operator who hangs the laundry looks at the hanging basket 15 Regardless of the direction, the drying performance displayed on the clothes rack 15 can be visually checked, and the operator can reliably recognize the degree of difficulty in drying.

The drying position to be made can be easily determined.

  Subsequently, the drying ability displayed on the surface of the clothes-drying basket 15 will be described.

  In FIG. 3, when the heated air blowing unit 3 is operated, the cross flow fan 6 is energized and airflow is blown out from the outlet 7, and the bathroom space 1 is indicated by a constant wind speed line C shown in the bathroom space 1 of FIG. 3. A uniform wind speed distribution is formed. Since the wind speed distribution in the bathroom space 1 depends on the condition of the airflow blown from the outlet 7 in a region where the wind speed is strong, the design specifications of the heating fan unit 3, the heating fan unit 3, and the laundry basket 15 are relatively provided. The wind speed distribution is uniquely determined according to the position.

  Since the surface heat transfer coefficient of the laundry is affected by the strength of the airflow around the laundry, the amount of heat transfer to the laundry increases as the wind speed around the laundry increases, and the drying capacity of each laundry There will be a difference. Therefore, the drying ability can be calculated with high accuracy by calculating the index of the drying ability of the laundry using the difference in the convective heat transfer coefficient on the laundry surface based on the strength of the airflow.

  In FIG. 4, the clothes basket 15 is attached with a sheet-like adhesive seal 20. The position where the adhesive seal 20 is attached to the axial direction of the clothes-drying basket 15 is determined according to the position of the heated air blowing unit 3. For example, the adhesive seal 20 is affixed to the laundry basket 15 so that the center line AA ′ of the heating air blowing unit 3 and the center line BB ′ of the adhesive seal 20 coincide with each other in plan view. The adhesive seal 20 is printed with a drying ability index 18 obtained by indexing the magnitude of the drying ability.

  Moreover, since the heating air blower unit 3 is provided in a ceiling, arrangement | positioning is decided by the relationship with the other installation with which the ceiling of the bathroom space 1 is provided, or a ceiling shape. Moreover, although both ends of the laundry basket 15 are fixed by wall surfaces, the arrangement of the laundry basket 15 is determined so that the laundry suspended by the laundry basket 15 does not contact the wall surface or the door. Accordingly, the heated air blowing unit 3 and the clothes-drying basket 15. Is determined by different factors, the relative positions of the heated air blowing unit 3 and the clothes-drying basket 15 cannot be uniform.

  Therefore, the accuracy of the drying capacity is improved by changing the display of the indicator of the drying capacity displayed on the surface of the drying basket in accordance with the change in the relative position between the heating air blowing unit 3 and the drying basket 15. Therefore, a plurality of adhesive seals 20 having different printed drying capacity indexes 18 are prepared, and the adhesive seal 20 can be selected in accordance with the situation where the heating air blowing unit 3 and the laundry basket 15 are installed. ing. Therefore, it is possible to display an indicator of the drying capacity in accordance with the installation status of the heating air blowing unit 3 and the clothes drying basket 15.
