  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a conceptual diagram showing the design principle of a cloth material processing apparatus 1 according to the first embodiment of the present invention.

  The cloth material processing apparatus 1 includes a housing 2 and an airflow generation system 3. The housing 2 defines the accommodation space SR. The user can arrange the cloth material FB in the accommodation space SR. The cloth material FB may be clothes, towels, or other cloth pieces. The cloth material FB does not limit the principle of this embodiment at all.

  In the accommodation space SR, a hanging rod 4 capable of suspending the cloth material FB with a hanger or the like is disposed. The suspended cloth material FB is swung. The motor 5 detects the number of rotations by a rotation sensor (not shown).

  The airflow generation system 3 includes a first guide tube 31, a second guide tube 32, a blower unit 33, and a first setting unit 34. The air blower 33 sucks the air in the first guide tube 31, and the sucked air is sent from the air blower 33 to the second guide tube 32 and returned to the accommodation space SR. The first setting unit 34 sets the flow rate of the airflow.

The first guide tube 31 is provided with a temperature sensor 6 that measures the temperature of the air sucked from the accommodation space SR, and a purification device 7 that removes dust from the air that passes through the first guide tube 31. The second guide tube 32 is provided with a heating unit 8 that heats air that passes through the second guide tube 32, and an atomization unit 9 that supplies atomizing liquid to the air that passes through the second guide tube 32. ing.

  Detection signals of the temperature sensor 6 and the rotation sensor of the motor 5 are transmitted to the control unit 10, and the control unit 10 controls the motor 5, the setting unit 34, the air blowing unit 33, the heating unit 8, and the atomizing unit 9.

  In the above configuration, in the atomization liquid generation process by the atomization unit 9 or the drying process by the heating unit 8, the torque of the motor 5 is increased at a constant speed at the start of the process, and the rotation speed of the motor 5 at that time is increased. The capacity of the fabric material FB is detected by measuring the rate.

  As shown in FIG. 2, even if the rate of increase in torque of the motor 5 is constant, the number of rotations of the motor 5 obtained from the rotation sensor 11 differs depending on the capacity of the cloth material FB. When the capacity of the cloth material FB is large, the torque required to increase the rotational speed of the motor 5 is large. On the other hand, when the capacity of the cloth material FB is small, the torque required to increase the rotational speed of the motor 5 is small. Therefore, it is possible to detect the capacity of the cloth material FB based on the relationship between the torque of the motor 5 and the rotation speed.

  The operation will be described based on the flowchart shown in FIG. In step S100, the operation is started. In step S110, the torque of the motor 5 is increased at a constant speed. In step S120, it is determined whether or not the rotational speed of the motor 5 has reached the rotational speed at which the capacity detection of the cloth material FB is started. If so, the process proceeds to step S130.

  In step S130, a capacity detection timer is started. In step S140, the torque of the motor 5 is continuously increased at a constant speed. In step S150, it is determined whether the rotational speed of the motor 5 has reached the rotational speed at which the capacity detection of the cloth material FB is completed. If so, the process proceeds to step S160.

  In step S160, the capacity detection timer is stopped, and in step S170, if the time during which the rotation speed increase period of the motor 5 is measured is short, the process proceeds to step S171 and the capacity is determined to be small. In step S170, if the measurement time is not a short time, the process proceeds to step S180. In step S180, if the time during which the rotation speed increase period of the motor 5 is measured is a long time, the process proceeds to step S181, and the large capacity. Is determined. In step S181, if it is not a long time, the process proceeds to step S190, and the medium capacity is determined.

  When the capacity of the cloth material FB is small, the amount of atomizing liquid to be attached to the entire cloth material FB is small. Therefore, it is possible to reduce power consumption by shortening the time of the atomizing liquid generating process. Similarly, since the amount of the atomized liquid adhering to the cloth material FB is small, it is possible to shorten the time of the drying process and reduce the power consumption.

(Embodiment 2)
As shown in FIG. 4, the atomizing liquid of the fabric material FB is measured by measuring the torque for periodically rotating the motor 5 during the atomizing liquid generating process by the atomizing unit 9 and detecting the torque fluctuation. Detect the degree of adhesion. Since the weight of the cloth material FB continues to increase due to the influence of the atomizing liquid adhering to the cloth material FB until the atomizing liquid adheres to the entire cloth material FB, the torque of the motor 5 also increases. On the other hand, after the atomizing liquid adheres to the entire cloth material FB, the atomizing liquid does not adhere to the cloth material FB any more, so the weight of the cloth material FB does not change. Therefore, the degree of adhesion of the atomized liquid to the cloth material FB can be detected by the change in the motor 5 torque.

  The operation will be described based on the flowchart shown in FIG.

  When the operation is started in step S200, the torque of the motor 5 is increased in step S210, and the rotation speed of the motor 5 is increased. In step S220, it is determined whether or not the rotation speed that is the target of the atomizing liquid generation process has been reached. When the rotation speed reaches the target rotation speed, the process proceeds to step S230. In step S230, the torque of the motor 5 is controlled so that the rotational speed of the motor 5 becomes the target rotational speed of the atomizing liquid generation step.

  In step S240, it is determined whether or not a predetermined time has elapsed. When the predetermined time has elapsed, the process proceeds to step S250. In step S250, the torque of the motor 5 when a predetermined time elapses is stored, and in step S260, the previously stored torque of the motor 5 is compared with the torque of the motor 5 stored this time.

  In step S260, if the torque of the previous memory is equal to the torque of the current memory, the process proceeds to step S270. If the torque of the motor 5 is the same for a predetermined number of consecutive times, the entire fabric material FB is fogged. It is determined that the atomizing liquid has adhered, and the atomizing liquid generating step is terminated.

  When the atomizing liquid adheres to the entire cloth material FB, there is no room for the atomizing liquid to adhere to the cloth material FB, and thus the atomizing liquid does not adhere. Therefore, after the atomizing liquid adheres to the entire cloth material FB, the performance is not improved even if the atomizing liquid generating process is continued. Therefore, when it adheres to the whole cloth material FB, the amount of power consumption can be reduced by terminating the atomization liquid generation process and shortening the atomization liquid generation process time.

(Embodiment 3)
As shown in FIG. 6, during the drying process by the heating unit 8, torque for periodically rotating the motor 5 is measured, and the degree of drying of the cloth material FB is detected by detecting the torque fluctuation. Since the weight continues to decrease due to the influence of the atomizing liquid adhering to the cloth material FB until the atomizing liquid of the cloth material FB is dried, the torque for rotating the motor 5 also decreases. On the other hand, since the weight change does not occur after the atomized liquid of the cloth material FB is dried, the weight does not change. Therefore, it is possible to detect the degree of drying of the cloth material FB based on a change in torque for rotating the motor 5.

  The operation will be described based on the flow church shown in FIG.

  In step S300, the drying process is started, and in step S310, the torque of the motor 5 is controlled so that the rotational speed of the motor 5 becomes the target rotational speed of the drying process. In step S320, it is determined whether or not a predetermined time has elapsed. When the predetermined time has elapsed, the process proceeds to step S330. In step S330, the torque of the motor 5 is stored. In step S340, the previously stored torque of the motor 5 is compared with the torque of the motor 5 stored this time, and it is determined whether the torques are equal. If the torques are equal in step S340, the process proceeds to step S350, and it is determined whether the torque of the motor 5 is equal for a predetermined number of consecutive times. If the torque of the motor 5 is equal for a certain number of times in step S350, it is determined in step S360 that the fabric material FB has dried, and the drying process is terminated.

  In the state where the drying of the fabric material FB is completed, the performance is not improved even if the drying is continued. Therefore, when the fabric material FB is dried, the power consumption can be reduced by terminating the drying process and shortening the drying process time.

(Embodiment 4)
As shown in FIG. 8, during the drying process by the heating unit 8, the rotation speed of the motor 5 is changed depending on the degree of drying of the cloth material FB. It is possible to reduce the bending of the cloth material FB by changing the rotation speed of the motor 5 depending on the degree of drying of the cloth material FB.

  Based on FIG. 9, control for changing the number of revolutions of the motor 5 during the drying process of FIG. 8 will be described.

  In step S500, a drying process is started. In step S510, the torque of the motor 5 is controlled so that the rotation speed of the motor 5 becomes the rotation speed targeted for the drying process. In step S520, it is determined whether or not a fixed time has elapsed since the start of the drying process.

  In step S530, the torque of the motor 5 when a predetermined time elapses is stored, and in step S540, the torque of the motor 5 stored for the first time is compared with the torque of the motor 5 stored this time. In step S540, when the rate of change of torque becomes equal to or greater than a certain level, the process proceeds to step S550, where the target rotational speed is changed.

  In step S540, the state in which the rate of change in the torque of the motor 5 is greater than or equal to a certain value can be determined as a state in which the amount of atomized liquid adhering to the cloth material FB is decreasing. In the state where the atomizing liquid is not attached to the cloth material FB, the cloth material FB is bent, thereby causing fiber bending and wrinkles. Therefore, by lowering the number of revolutions of the motor 5, it is possible to prevent the fabric material FB from being bent and to prevent the fiber from being bent.

(Embodiment 5)
As shown in FIG. 10, during the drying process by the heating unit 8, after the temperature sensor 6 detects a temperature above a certain level, the degree of drying of the fabric material FB is detected. After the temperature sensor 6 detects a temperature equal to or higher than a certain level, it is possible to reduce the erroneous detection of the degree of drying by detecting the degree of drying of the fabric material FB.

  The operation of the fifth embodiment will be described based on the flowchart shown in FIG.

  In step S400, a drying process is started, and in step S410, heating is performed by the heating unit 8. In step S420, when the temperature sensor 6 detects a temperature equal to or higher than a certain temperature, in step S430, detection of the degree of drying is started.

  In a state where the temperature sensor 6 does not detect a constant temperature, the inside of the housing 2 is in a state where the temperature has not risen, and the atomized liquid adhering to the cloth material FB is not dried. Therefore, if the detection of the degree of drying due to the torque change of the motor 5 is started before the temperature sensor 6 detects a temperature equal to or higher than a certain temperature, there is a possibility that the drying is finished before the drying of the cloth material FB is started. is there. For this reason, the detection of the degree of drying is not performed before the inside of the housing 2 rises between the temperatures at which the atomized liquid adhering to the cloth material FB is dried, thereby reducing false detection of the degree of drying. Is possible.
