  FIG. 1 is a diagram schematically showing a spray processor in the present embodiment. 1A is a front view of the spray processor 100, and FIG. 1B is a right side view of the spray processor 100. FIG.

  The spray processor 100 is used for the purpose of uniformly moistening the dried laundry. Laundry can be stretched and dried by spreading and ironing with some moisture. This is the same whether a home iron or a business roll ironer is used. For example, when a roll ironer is used to wrinkle and dry laundry such as sheets, if the laundry is not properly spread when it is put into the roll ironer, it will dry with a crease. This will result in poor finish.

  The laundry that has been poorly finished as described above needs to be moistened again and then applied to the roll ironer, but it is useless to perform washing again only to moisten it. Moreover, although the method of giving dampness with a mist spray etc. can also be considered, it takes time and it is difficult to wet the laundry uniformly. Therefore, in order to uniformly moisten the laundry once dried in this way, the spray processor 100 in the present embodiment is used. In the present embodiment, the state in which the drying rate of the laundry is several percent or less of the absolute humidity in the atmosphere is assumed to be that the laundry is in a dry state, and the laundry in such a dry state is evenly distributed. Moisten. Hereinafter, the details of the spray processor 100 in the present embodiment will be described.

  As shown in FIGS. 1 (a) and 1 (b), the spray processor 100 includes a rotary drum 101, a drive motor 102, a drive roller 103, a front door 104, spray nozzles (spray nozzles) 105, 106, and 107.

  The rotary drum 101 is supported so as to be rotatable around the horizontal axis of the spray processor 100, and both front and rear ends are open in the front view shown in FIG. Further, in the right side view shown in FIG. 1B, the left and right ends are opened. In the present embodiment, in order to unify the expression, it is assumed that both the left and right ends of the rotating drum 101 are open based on the right side view shown in FIG. That is, the rotating drum 101 has a left opening 101b and a right opening 101c.

  Inside the rotating drum 101, dry laundry put in from the front door 104 is accommodated. The rotating drum 101 is rotated around the horizontal axis of the spray processor 100 by a driving roller 103 driven by a driving force of a driving motor 102. Inside the rotating drum 101, four crosspieces 101a are installed along the inner circumference at intervals of 90 degrees.

  The crosspiece 101a extends from the left opening 101b of the rotating drum to the right opening 101c. With the crosspiece 101a, the laundry collected at the bottom of the rotary drum 101 is scraped upward as the rotary drum 101 rotates. In this embodiment, an example in which four crosspieces 101a are installed in the rotating drum 101 will be described. However, this number is not limited to four, and the number of installation may be changed depending on the size of the rotating drum 101. It may be. Further, a ventilation hole 101d, for example, a punching hole indicated by a dotted line in FIG. 1B is formed in the inner peripheral surface of the rotating drum 101, and the inner peripheral surface of the rotating drum 101 is configured to be air permeable.

  FIG. 2 is a diagram schematically showing a state in which the laundry is scraped up by the crosspiece 101 a as the rotating drum 101 rotates. FIG. 2A shows a state where the laundry is fried up when the rotational speed of the rotary drum 101 is low. That is, when the rotational speed of the rotary drum 101 is low, the laundry that has been lifted upward by the crosspiece 101a falls due to gravity, and thus is scattered in the rotary drum 101.

  On the other hand, FIG. 2 (b) shows a state where the laundry is fried up when the rotational speed of the rotary drum 101 is high. That is, when the rotational speed of the rotating drum 101 becomes equal to or higher than a certain rotational speed, the laundry that is lifted upward by the crosspiece 101 a is rotated by the centrifugal force generated by the rotation of the rotating drum 101. It will be in the state of sticking almost uniformly on the inner peripheral surface.

  The spray nozzles 105 are installed in two upper portions so as to face the left-side opening 101b of the rotating drum 101, that is, facing the left-side opening 101b of the rotating drum 101 so that the direction of each nozzle is obliquely downward. Thus, mist is sprayed from the spray nozzle 105 toward the center of the rotary drum 101 from the front side of the spray processor 100, that is, from the upper part of the left opening 101 b of the rotary drum 101. The two spray nozzles 105 are accommodated in the nozzle cover 105a, and are arranged at predetermined intervals in the horizontal direction with the center of the rotating drum interposed therebetween.

  The spray nozzles 106 are installed in two upper portions so as to face the right opening 101c of the rotating drum 101, that is, facing the right opening 101c of the rotating drum 101 so that the directions of the respective nozzles are obliquely downward. As a result, mist is sprayed from the spray nozzle 106 toward the center of the rotating drum 101 from the back side of the spray processor 100, that is, from the upper part of the right opening 101 c of the rotating drum 101. The two spray nozzles 106 are accommodated in the nozzle cover 106a, and are arranged at predetermined intervals in the horizontal direction with the center of the rotating drum interposed therebetween.

  The spray nozzle 107 is installed at two lower positions so as to face the right opening 101c of the rotating drum 101, that is, facing the right opening 101c of the rotating drum 101 so that the nozzles are directed obliquely upward. As a result, mist is sprayed from the spray nozzle 107 toward the center of the rotating drum 101 from the back side of the spray processor 100, that is, from the lower part of the right opening 101 c of the rotating drum 101. The two spray nozzles 107 are accommodated in the nozzle cover 107a, and are respectively arranged at predetermined intervals in the horizontal direction with the center of the rotating drum interposed therebetween.

  In addition, mist means the mist-like water sprayed from the nozzle part 3a which squeezed the spray nozzle finely as shown in FIG. The mist also includes warm water and steam sprayed from the finely squeezed nozzle portion 3a.

  The spray processor 100 includes a control device (not shown), and the rotation of the rotating drum 101 and the spray of mist from each spray nozzle are controlled by the control device. The control device includes, for example, a CPU, a memory, and other peripheral circuits, and the CPU executes a control program recorded in the memory, thereby executing processing for controlling the spray processor 100.

  The spray processor 100 includes an operation member (not shown), and the user can instruct the start and end of the operation of the spray processor 100 by operating the operation member. The said control apparatus operates the spray processing machine 100 based on the operation signal output from an operation member, when an operation member is operated by the user. Specifically, the control device starts the spraying process as follows when the user puts the laundry into the rotating drum 101 and operates the operation member to instruct the start of the spraying process.

  First, the control device controls the drive motor 102 to start the rotation of the rotary drum 101. At this time, the control device controls the rotation direction and rotation speed of the rotating drum 101 as shown in FIG. Specifically, after starting the forward rotation driving of the rotating drum 101 in the right direction, the control device gradually increases the rotational speed to reach the maximum rotational speed, for example, 40 to 45 rpm, and reaches the maximum rotational speed for a predetermined time. For example, the rotating drum is rotated for 5 to 10 seconds. Thereafter, the control device gradually decreases the rotational speed of the rotary drum 101 and changes the rotational direction of the rotary drum to the left when the rotational speed reaches zero.

  After starting the reverse rotation driving of the rotating drum 101 in the left direction, the control device gradually increases the rotation speed to reach the maximum rotation speed, for example, 40 to 45 rpm, and reaches the maximum rotation speed for a predetermined time, for example, 5 to 10 seconds. Rotate the rotating drum. Thereafter, the control device gradually decreases the rotational speed of the rotary drum 101, changes the rotational direction of the rotary drum to the right when the rotational speed reaches zero, and starts normal rotation driving again. By repeating this, the control device drives the rotating drum 101 intermittently while repeating forward rotation and reverse rotation.

  Note that the control device continues the repetition of the normal rotation drive and the reverse rotation drive of the rotary drum 101 for a time required to uniformly moisten the laundry by spraying mist described below, for example, 10 minutes. The total time for repeating the forward drive and the reverse drive may be set in advance, or may be arbitrarily set by the user according to the amount of laundry. Alternatively, the control device may detect the amount of laundry and set an optimal time according to the amount of laundry.

  Then, as shown in FIG. 4B, the control device rotates the rotating drum 101 from each of the spray nozzles 105 to 107 while the rotational speed of the rotating drum 101 in the normal rotation driving and the reverse driving reaches the maximum rotating speed. Spray mist inside. As a result, when the rotational speed of the rotating drum 101 is high, that is, as described above, the laundry that has been lifted upward by the crosspiece 101a is stuck almost uniformly on the inner peripheral surface of the rotating drum 101 by centrifugal force. Mist can be sprayed in the state.

  As a result, the mist sprayed from each of the spray nozzles 105 to 107 falls into the rotating drum 101 and adheres to the laundry stuck to the lower portion of the rotating drum 101 one after another. As a result, all the laundry in the rotary drum 101 can be moistened evenly.

  Further, in the present embodiment, the mist is sprayed while the rotation speed of the rotary drum 101 reaches the maximum rotation speed while alternately switching the rotation direction of the rotation drum 101 between the normal rotation direction and the reverse rotation direction. did. As described above, by alternately switching the rotation direction of the rotating drum 101 between the normal rotation direction and the reverse rotation direction, the laundry once falls on the lower portion of the rotating drum 101 at the timing when the rotation direction is switched, and then again by the crosspiece 101a. It is lifted up and sticks almost uniformly to the inner peripheral surface. Accordingly, the surface of the laundry to which the mist adheres can be changed every certain time, so that the mist can be sprayed uniformly on the entire laundry and the laundry can be moistened uniformly.

  The user can stretch the wrinkles of the laundry and dry it by ironing or even passing it through the roll ironer.

According to the present embodiment described above, the following operational effects can be obtained.
(1) The control device drives the rotary drum 101 to rotate, and the crosspiece 101a rakes the laundry so that the laundry is stuck to the inner peripheral surface of the rotary drum 101, and the mist is placed inside the rotary drum 101. Was sprayed. As a result, the mist falls into the rotating drum 101 and adheres to the laundry stuck to the lower portion of the rotating drum 101 one after another. The laundry can be moistened evenly.

(2) The rotating drum 101 is open at both left and right ends, and mist is sprayed into the rotating drum 101 from the openings at both ends. Thereby, since mist can be spread in the rotating drum 101, the laundry can be moistened efficiently.

(3) The spray nozzles 105 to 107 are installed so as to face the opening at one end of the rotary drum 101, respectively. As a result, mist can be sprayed from the opening of the rotating drum 101 into the inside.

(4) The control device rotates the rotating drum 101 intermittently while repeating the forward rotation driving and the reverse rotation driving, and the mist in the rotating drum 101 is reached while the rotation speed of the rotating drum 101 reaches the maximum rotation speed. Was sprayed. As a result, the laundry once falls to the lower part of the rotating drum 101 at the timing when the rotation direction is switched, and then is again swept up by the crosspiece 101a and stuck almost uniformly on the inner peripheral surface, so that mist adheres. The surface of the laundry can be changed at regular intervals, and the laundry can be uniformly moistened by spraying mist uniformly on the entire laundry.

-Modification-
In addition, the spray processing machine of embodiment mentioned above can also be deform | transformed as follows.
(1) In the above-described embodiment, the rotating drum 101 has been described as an example in which both the left and right ends are open as shown in FIG. However, the rotating drum 101 only needs to open at least one of the left and right ends. In this case, the spray nozzle may be installed opposite to the open end.

(2) In embodiment mentioned above, the spray processor 100 demonstrated the example provided with the spray nozzle 105,106,107. However, only one of the spray nozzles may be provided. Further, any two spray nozzles may be provided in combination. Note that the number of spray nozzles mounted on the spray processor 100 may be determined at the time of design based on the size of the rotating drum 101.

(3) In the above-described embodiment, the control device describes an example in which mist is sprayed into the rotary drum 101 while the rotation speed of the rotation drum 101 in the forward rotation drive and the reverse rotation drive reaches the maximum rotation speed. did. However, the control device does not necessarily have to continue spraying mist while the rotation speed of the rotary drum 101 reaches the maximum rotation speed. For example, the control device may spray mist into the rotating drum 101 during a part while the rotating speed of the rotating drum 101 reaches the maximum rotating speed.

(4) In the above-described embodiment, the control device describes an example in which mist is sprayed into the rotating drum 101 while the rotation speed of the rotation drum 101 in the normal rotation drive and the reverse rotation drive reaches the maximum rotation speed. did. However, the control device may spray the mist into the rotating drum 101 while the rotating speed of the rotating drum reaches a predetermined rotating speed or more or during a part thereof. The predetermined rotation speed in this case is necessary for the laundry in the rotating drum 101 to be in a state of being stuck almost uniformly on the inner peripheral surface of the rotating drum 101 as shown in FIG. A sufficient number of revolutions is set to generate a centrifugal force.

(5) In the above-described embodiment, the control device causes the rotating drum 101 to drive forward in the right direction, then reversely drives in the left direction, and repeats this to drive the rotating drum 101 intermittently. explained. However, the control device may drive the rotating drum 101 intermittently only in one direction of the right direction or the left direction. Also in this case, since the laundry once falls to the lower part of the rotating drum 101 at a timing between the stop and start of rotation, it is swept up again by the crosspiece 101a and stuck almost uniformly on the inner peripheral surface. As in the embodiment described above, the laundry can be uniformly moistened.

(6) The spray processor 100 is further provided with a blower opening for blowing warm air inside the rotating drum 101, and the control device is configured to blow warm air while spraying mist into the rotating drum 101. Also good. As the warm air blowing timing, it is sufficient that the warm air blowing timing and the mist spraying timing overlap at least partially. For example, the warm air blowing timing and the mist spraying timing may be completely matched, or the warm air may be continuously blown regardless of the mist spraying timing. The air outlet may be installed so as to blow warm air into the inside of the rotating drum 101 through the ventilation hole 101 d of the rotating drum 101. For example, an air outlet may be provided so that warm air passes from the upper vent hole of the rotating drum 101 to the lower vent hole.

  Alternatively, the air blowing port may be installed so as to blow warm air from the opening of the rotating drum 101 into the rotating drum 101. Note that when the hot air is blown from the opening of the rotating drum 101, it is not always necessary to provide a ventilation hole in the rotating drum 101. In this way, by blowing warm air while spraying mist into the rotating drum 101, the mist can be heated by the warm air to improve the penetration into the laundry, and more efficiently the laundry. Can be moistened. Moreover, the same effect is acquired by spraying warm water in mist form other than blowing warm air and heating mist.

(7) In the above-described embodiment, the control device causes each of the spray nozzles 105 to 107 to enter the rotary drum 101 while the rotation speed of the rotation drum 101 in the normal rotation drive and the reverse rotation drive reaches the maximum rotation speed. The example which sprays mist was demonstrated. However, the control device may continuously spray the mist continuously during the spraying process regardless of the rotational speed of the rotating drum 101. Even in this case, since the mist can be sprayed while the rotational speed of the rotating drum 101 reaches the maximum rotational speed, all the laundry in the rotating drum 101 is uniformly distributed as in the above-described embodiment. Can be moistened.

  Note that the present invention is not limited to the configurations in the above-described embodiments as long as the characteristic functions of the present invention are not impaired. Moreover, it is good also as a structure which combined the above-mentioned embodiment and a some modification.

It is the figure which showed the spray processing machine typically. It is the figure which showed typically the state where the laundry was fried up by the crosspiece. It is the figure which showed the detail of the spray nozzle typically. It is a figure which shows an example of the rotation direction of the rotating drum 101, a rotational speed, and the spray timing of mist.
