(1) Embodiment 1
(1-1) Overall Configuration of Drying Device FIG. 1 is a perspective view showing the entire drying device 100 for permeate according to Embodiment 1. FIG. The drying apparatus 100 simultaneously dries two mattresses 50 and 51 (see FIG. 3) after washing as an example of the permeation object into which the fluid has permeated. As will be described in detail later with reference to FIG. 3, the drying apparatus 100 includes a frame 103, a first drying air injection device 114 that is a first drying air injection means, and a second drying air that is a second drying air injection means. It includes an injection device 115 and drive means (the electric motor 116 shown in FIG. 3 corresponds to this).

  The frame 103 has a shaft 110 for rotating the frame 103 around its axis and attachment means for attaching the mattresses 50 and 51 to the shaft side portion of the frame 103 at a position away from the shaft 110 (a plurality of belts shown in FIG. 3). 113 corresponds to this), and the attached mattresses 50 and 51 are directed from the shaft side portion of the frame 103 to the shaft 110, that is, from the outside of the cylindrical portion of the frame 103 to the inside shaft 110. And a ventilation portion A for applying dry air.

  The first drying wind injection device 114 is provided on the outside of a rotating body (hereinafter simply referred to as a rotating body) that can be obtained by rotating the frame 103 around the axis 110, and is attached to the mattresses 50 and 51 attached to the frame 103. The dry air is injected. By injecting the drying air from the outside of the rotating body, the drying air strikes the outer surfaces 50a and 51a (see FIG. 3) of the mattresses 50 and 51 attached to the frame 103 through the ventilation portion A.

  The second drying wind injection device 115 is provided between the shaft 110 and the mattresses 50 and 51 attached to the frame 103, and the shaft 110 is attached to the inner surfaces 50b and 51b (see FIG. 3) of the mattresses 50 and 51. From which the drying air in the centrifugal direction is ejected.

  The driving means rotates the shaft 110 at a rotational speed C (number of revolutions / minute).

  A drying method of the mattresses 50 and 51 by the drying device 100 includes a step of attaching the mattresses 50 and 51 to the frame 103 by the attaching means, a shaft 110 being rotated by the driving means, and the first and second drying wind injection devices 114, 115, and injecting the drying air from 115.

  The rotational speed C (number of revolutions / minute) of the shaft 110 is a fluid that penetrates the mattresses 50 and 51 at a position where the drying air injected by the first drying air injection device 114 hits the outer surfaces 50a and 51a of the mattresses 50 and 51. Is set to a rotational speed at which centrifugal force acts. Hereinafter, the lower limit value of the rotational speed C (rotational speed / minute) that satisfies this condition is represented as rotational speed Cref (rotational speed / minute).

  The drying apparatus 100 rotates the shaft 110 at a rotational speed C (number of revolutions / minute) to apply a centrifugal force to the mattresses 50 and 51 attached to the frame 103 and penetrates the mattresses 50 and 51. The fluid is collected on the surface side around the axis of the rotating body, that is, the outer surfaces 50a and 51a, and rapid drying is realized by injecting the drying air from the outside of the rotating body toward the outer surfaces 50a and 51a.

  As long as the shaft 110 is rotated at a speed equal to or higher than the rotational speed Cref (number of revolutions / minute), the direction of the shaft 110 may be any of a substantially horizontal direction, a tilt direction, and a vertical direction.

  For example, unlike the state shown in FIG. 1, the case where the shaft 110 is provided in the vertical direction, and the case where the mattress 303a is placed in the drying chamber 300 with the surface 304 vertical as shown in FIG. Think. When the shaft 110 is provided in the vertical direction, the drying apparatus 100 removes all the liquid that has permeated the mattresses 50 and 51, including the liquid in the deep layers of the mattresses 50 and 51. Since they can be collected on the surface side to which the drying air is applied, that is, on the outer surfaces 50a and 51a, more rapid drying can be realized.

  Refer to FIG. 1 again. The drying apparatus 100 is provided with a shaft 110 in a substantially horizontal direction. The term “substantially horizontal” includes not only horizontal but also a state where the shaft is slightly inclined. By adopting this configuration, rapid drying can be realized. This is the case, for example, when the nozzle 114a of the first drying wind injection device 114 is provided at the same height as the shaft 110 when viewed in a plane perpendicular to the shaft 110 and the mattress 50, 51 moves downward. If the frame 103 is rotated once, the sum of the gravitational components acting on the liquid penetrating the mattresses 50 and 51 is completely cancelled. This is because the permeating fluid can be collected more quickly on the surface side around the axis of the rotating body of the frame 103, that is, on the outer surfaces 50a and 51a.

  As long as the shaft 110 is inclined, a gravity component acts in the centrifugal direction or in the direction opposite to the centrifugal direction, but it is preferable that the shaft 110 be in a substantially horizontal direction.

  For example, unlike the state shown in FIG. 1, the surface 304 of the mattress 303a is provided in the case where the first drying wind injection device 114 is provided at the lower position of the frame 103 and in the conventional drying chamber 300 shown in FIG. Consider the case of placing the horizon horizontally. The drying device 100 provided with 114a of the first drying air injection device 114 at the lower position of the frame 103 applies a larger amount of liquid to the surface to which the drying air is applied, that is, the outer surfaces 50a and 51a. Since they can be collected, more rapid drying can be realized.

  Refer to FIG. 1 again. The drying device 100 further includes a drying chamber 101, a ventilation device 102, an operation unit 104, and an instrument panel 105.

  The drying chamber 101 has an elevating door 106 for handling the housed frame 103.

  The ventilation device 102 includes a ventilation fan 102a and a duct 102b. The ventilation fan 102a discharges the air in the drying chamber 101 containing the liquid that has permeated the material to be permeated through the duct 102b.

  The operation unit 104 is for performing operation control of the apparatus. The operation unit 104 includes three switches 104a, 104b, and 104c. When the switch 104a is pressed, the first and second drying wind injection devices 114 and 115 and the driving means are started. When the switch 104b is pressed after the switch 104a is pressed, for example, a time T1 (experimental value) required for substantially completely drying the mattresses 50 and 51 after washing in a state of impregnating about 60% of the liquid has passed. Later, the operation of the first and second drying wind injection devices 114 and 115 and the driving means stops. When the switch 104c is pressed, the operation of the first and second drying wind injection devices 114 and 115 and the driving unit is immediately stopped. A detailed configuration of the operation unit 104 will be described later.

  The instrument panel 105 is provided with various meters for confirming the temperature in the drying chamber 101 and the operation state of the apparatus.

(1-2) Configuration of Operation Unit FIG. 2 is a configuration diagram of the operation unit 104. The operation unit 104 further includes a power source 104d, a control circuit 104e, and a timer 104f in addition to the switches 104a, 104b, and 104c described above. The first and second drying wind injection devices 114 and 115 are electric devices using an electric heater. As will be described later, the first and second drying air injection devices 114 and 115 share the drying air generator 120 (see FIG. 5) that generates the drying air. The control circuit 104e supplies power from the power source 104d to the first and second dry wind generators 114 and 115 and the electric motor 116 that is a driving unit in response to pressing of the switch 104a. In response to pressing of the switch 104b, the timer 104f starts. The control circuit 104e supplies power from the power source 104d to the first and second dry air injection devices 114 and 115 and the electric motor 116 in response to the end of the time T1 measurement by the timer 104f or the pressing of the switch 104c. To stop.

  When the operator presses the switch 104a, the drying process is started, and the drying process is continued until the operator presses the switch 104c. When the drying time is changed according to the liquid impregnation rate of the mattresses 50 and 51 to be dried, the drying process is performed according to the procedure. When the mattresses 50 and 51 to be dried are in a state of impregnating about 60% of the liquid, after the switch 104a is pressed, the switch 104b is pressed and the drying process at time T1 is performed.

  As the first and second dry wind injection devices 114 and 115, those that use a thermal power such as gas or oil that starts in response to a signal are adopted, and the internal combustion engine that starts in response to a signal is used as the motor 116. You may employ what is used. In this case, the control circuit 104e outputs a signal for starting each device to the first and second dry wind injection devices 114 and 115 and the motor 116 instead of supplying the power.

(1-3) Frame, First, and Second Drying Air Injection Device FIG. 3 is a perspective view showing the components housed in the drying chamber 101. A support structure 200 is housed in the drying chamber 101. The support structure 200 is provided with a frame 103, a first dry air injection device 114, a second dry air injection device 115, and an electric motor 116.

  Both ends of the shaft 110 of the frame 103 are supported by the support structure 200 in a rotatable state. The frame 103 is a cylindrical frame having a diameter of about 1540 mm and an axial length of about 1270 mm, which is rotatable about an axis 110, and is 2 along the axial side of the cylindrical part, that is, along the inner side. One mattress 50, 51 can be stored.

  In the cylindrical portion of the frame 103, two mattresses 50 and 51 are inserted along the axial side, that is, the inner side of the portion, and an opening 111 for attaching to the frame 103, and an opening / closing mechanism 112 for the opening 111 are provided. And are provided. The configuration of the opening / closing mechanism 112 will be described later.

  The frame 103 has a plurality of belts 113 as attachment means for attaching the two mattresses 50 and 51 to the frame 103. The mattresses 50 and 51 inserted into the frame 103 through the openings 111 are fixed by a plurality of belts 113.

  The attachment means is designed so that dry air injection nozzles 114a and 115a of first and second dry air injection devices 114 and 115, which will be described later, can be provided as close as possible to the mattresses 50 and 51. Preferably, instead of the plurality of belts 113, for example, radial support members 107a and 107b that support the annular members 103a and 103b of the frame 103 are provided with an annular member having a small diameter corresponding to the thickness of the mattresses 50 and 51. It may be attached as a material.

  The cylindrical portion of the frame 103 is composed of ten annular members 103c to 103l in a state where the opening portion 111 is missing, and a plurality of rod-like members 117 parallel to the rotation axis. The plurality of rod-shaped members 117 fix the ten annular members 103c to 103l so as to be arranged coaxially at intervals. The ventilation portion A refers to a plurality of lattice-shaped portions formed by the intersection of ten annular members 103c to 103l and a plurality of rod-shaped members 117.

  If the frame 103 satisfies the condition of having the shaft 110, the attachment means, and the ventilation portion A, for example, only one mattress 50 can be accommodated along the shaft 110. It is also conceivable to use a semi-cylindrical frame having a flat surface.

  The first drying air injection device 114 has a nozzle 114 a having a length substantially the same as that of the shaft 110 of the frame 103 at a portion where the drying air is injected. The nozzle 114a is provided near the outside of the rotating body. FIG. 4A shows an AA sectional view including the nozzle 114a.

  The first drying air injection device 114 vaporizes the liquid by directly applying the drying air to the outer surfaces 50a and 51a of the rotating mattresses 50 and 51 through the ventilation portion A in order to satisfy the drying air. This eliminates the need to make the drying chamber 101 airtight and contributes to simplification of the drying apparatus 100.

  The first drying air injection device 114 applies the drying air over the entire outer surfaces 50a and 51a of the mattresses 50 and 51 by rotating the shaft 110 while the drying air is being injected from the nozzle 114a. In comparison with the case where the drying chamber 101 is filled with drying air, less drying air is wasted and a small and low power consumption type can be used.

  The first drying air injection device 114 is configured to inject the drying air to the mattresses 50 and 51, and when the drying air has the same degree of drying, the larger the air amount injected per unit time (hereinafter referred to as the drying air amount), It can be quickly dried (see experimental data below). However, as described above, the first drying air injection device 114 injects the drying air to the liquid collected on the outer surfaces 50a and 51a of the mattresses 50 and 51. For example, the outer surfaces 50a and 51a of the mattresses 50 and 51 are injected. The same performance as in the case where the liquid in the deep layer is vaporized by injecting the drying air with a force that reaches the deep layer of the mattress 50, 51 without applying a force to collect the liquid on It has the advantage that a relatively low output can be used to exhibit the above.

  The second drying air injection device 115 has a nozzle 115 a having a length substantially the same as that of the shaft 110 of the frame 103 at a portion where the drying air is injected. The nozzle 115 a is provided near the inside of the frame 103. FIG. 4B shows a BB cross-sectional view including the nozzle 115a.

  The second drying air injection device 115 applies the drying air from the shaft 110 in the centrifugal direction to the surfaces of the mattresses 50 and 51 facing the shaft 110, that is, the inner surfaces 50b and 51b, and further rotates the frame 103. Is a means for passing dry air through the mattresses 50 and 51 to vaporize the liquid in the deep layer portion by utilizing the flow of air from the shaft 110 side toward the outside of the frame 103, which is generated along with the first dry air. The function of the injection device 114 is aided. The second drying air injection device 115 can perform quick drying as the amount of drying air to be injected increases (see experimental data described later).

  The shaft 110 is connected to the electric motor 116 by a drive belt 116a. When driven by the control circuit 104e, the electric motor 116 rotates the shaft 110 at a rotational speed C (number of revolutions / minute).

  The rotational speed Cref (number of revolutions / minute) varies depending on the position where the first drying wind injection device 114 is provided because the gravity component acting in the centrifugal direction varies. As shown in FIG. 3, the case where the 1st dry wind injection apparatus 114 exists in the position of 1 to 2 o'clock with a timepiece is considered. In this position, to apply a centrifugal force, that is, a force toward the outside of the rotating body as viewed from the shaft 110, to the liquid penetrating the mattresses 50 and 51, the rotation speed of the frame 103 is applied to the liquid. It is necessary to set a speed at which a centrifugal force larger than the gravity component acting in the direction of the axis 110 acts.

  FIG. 5 is a perspective view of the frame 103 as viewed from the opposite side to FIG. The drying chamber 101 is omitted. The support structure 200 includes a dry air generator 120 shared by the first and second dry air injection devices 114 and 115. The drying wind generator 120 sucks the air in the drying chamber 101, generates the drying wind by heating the sucked air, and injects the generated drying wind from the nozzles 114a and 115b through the ducts 114b and 115b. Let The dry air generator 120 may be of a type that dehumidifies the suctioned air. Alternatively, air may be sucked from the outside of the drying chamber 101 (see FIG. 3). The ducts 114b and 115b are provided with valves 114c and 115c so that the ducts 114b and 115b can be arbitrarily closed when an experiment described later is performed.

(1-4) Configuration of Opening / Closing Mechanism FIGS. 6 and 7 are enlarged views of a portion surrounded by a broken line C in FIG. 3, and are perspective views for explaining the configuration of the opening / closing mechanism 112 provided in the opening 111 of the frame 103. FIG. 6 shows a state in which the opening / closing mechanism 112 is opened, and FIG. 7 shows a state in which the opening / closing mechanism 112 is closed.

  The opening / closing mechanism 112 includes ten four-stage telescopic rods 130a, 130b,..., 130j (not shown) and one frame constituting rod 131a.

  Each of the ten four-stage telescopic rods 130a, 130b,..., 130j has the same diameter as the cylindrical portion of the frame 103 and extends along the rotation direction of the frame 103, and has one end at one end. As shown in FIGS. 3 and 6, the opening 111 is connected to a frame 111a parallel to the axis 110 of the opening 111 at equal intervals, and the other end is attached to the frame constituting rod 131a.

  The frame constituting rod 131a extends in parallel with the shaft 110, and both end portions thereof are slidable on the annular members 103a (see FIG. 3) and 103b of the frame 103 in the rotation direction of the frame. It is supported by. FIG. 6 shows an end 131ar of the frame constituting rod 131a on the annular member 103b side. The frame constituting rod 131a slides along the rotation direction of the frame 103 with the same diameter as the cylindrical portion, and opens and closes the opening by ten telescopic rod rods 130a, 130b,. Three frame constituting rods 131b, 131c, 131d having the same structure as the frame constituting rod 131a are attached to the distal ends of the extending portions of the telescopic rods 130a, 130b, 130c,. Furthermore, in order to make each space | interval of the flame | frame 111a of the opening 111 arranged in order and the four frame structure rods 131a-131d equal intervals, the coupling device 132a comprised by a pair of connecting rods connected with the hinge. ~ 132d are provided.

  The opening / closing mechanism 112 has the same diameter as the cylindrical portion of the frame 103 and slides along the rotation direction of the frame 103. By adopting this configuration, the opening / closing mechanism 112 makes it possible to provide the nozzles 114a and 115a of the first and second dry-air injection devices 114 and 115 closer to the mattresses 50 and 51, which is wasted. By reducing the drying air, it is possible to contribute to the realization of faster drying.

(2) Examination of Experimental Results Six graphs (a) to (f) shown in FIG. 8 show the rotation speed of the shaft 110 and the first and second drying air injection devices 114 and 115 in the drying device 100 having the above-described configuration. The mattresses 50 and 51 after washing with the liquid impregnated with about 10% of the liquid were dried almost completely (the liquid impregnation rate was substantially 0%). The experimental result when it is made to show is shown. The vertical axis of the graph represents the weight (kg) of the mattresses 50 and 51, and the horizontal axis represents the elapsed time (minutes) since the switch 104a was pressed.

The graph (a) is a case where only the second drying air injection device 115 is driven to inject 80 ° C. drying air and the frame 103 is rotated at a low speed C _low = 24 (rotations / min). . Only the second dry air injection device 115 is driven by closing the valve 114c (see FIG. 5) of the duct 114b and allowing the dry air output from the dry air generating device 120 to pass through only the duct 115b. It is assumed that the temperature and humidity of the air sucked into the dry wind generator 120 are uniform. In this setting, the higher the temperature of the air to be injected, the drier the air. The low-speed rotation C _low means a speed that is faster than the rotation speed Cref (rotation number / minute), but is lower than a _high- speed rotation C _high (rotation number / minute) described later.

The graph (b) shows a case where the first and second drying air injection devices 114 and 115 are driven to inject the 80 ° C. drying air and the frame 103 is rotated at a low speed C _low (number of rotations / minute). belongs to.

The graph (c) drives the first and second drying air injection devices 114 and 115 to inject 100 ° C. drying air and causes the frame 103 to rotate at a high speed C _high = 102 (revolutions / minute). Is the case.

The graph (d) shows that the valve 115c (see FIG. 5) of the duct 115b is closed, thereby driving only the first drying air injection device 114, injecting 100 ° C. drying air, and rotating the frame 103 at high speed C. _{This is for high} (rpm / min).

In the graph (e), by closing the valve 114c of the duct 114b, only the second dry wind injection device 115 is driven to inject 100 ° C. dry air, and the frame 103 is rotated at a high speed C _high (number of revolutions / minute). ).

In the graph (f), by closing the valve 114c of the duct 114b, only the second dry air injection device 115 is driven to inject 100 ° C. dry air, and the frame 103 is rotated at a low speed C _low (number of revolutions / minute). ).

  When the graph (a) and the graph (b), and the graph (c) and the graph (e) are compared, it is found that the first drying wind injection device 114 is provided with higher drying efficiency. . In addition, the first drying air injection device 114 has a higher drying efficiency as the temperature (dryness) of the drying air is higher and the rotation speed is faster. However, by increasing the rotation speed, the drying efficiency is greatly increased. I knew it would be better. This can be considered that the faster the rotation speed, the faster the liquid that has penetrated into the deep layers of the mattresses 50, 51 can be collected on the outer surfaces 50a, 51a of the mattresses 50, 51.

  Further, when comparing the graph (c) and the graph (d), it was found that not only the first dry wind injection device 114 but also the second dry wind injection device 115 was provided, and the drying efficiency was improved. . Further, comparing the graph (a) and the flag (f), it was found that the higher the drying air temperature (dryness), the higher the drying efficiency of the second drying air injection device. Comparing the graph (e) and the graph (f), it was found that the drying efficiency of the second drying wind injection device does not improve much even if the rotation speed of the frame 103 is increased.

  From the above experiments, the drying efficiency of the drying apparatus 100 is such that the rotational speed of the frame 103 is high, and the temperature of the drying air injected by the first and second drying air injection devices 114 and 115 is high, that is, the drying device is more dry. It turned out that it became so high that the dry wind of a state was injected.

For convenience of explanation, components of the drying apparatus according to Embodiment 3 to be described later are indicated by broken lines. In the drying apparatus according to the second embodiment, a switch 104g, a control circuit 104h, and a timer 104i are added to the operation unit 104 shown in FIG.

  In response to pressing of the switch 104g, the control circuit 104h converts the output of the power supply 104d into a high voltage and then supplies it only to the electric motor 116 operating with a DC power supply. The electric motor 116 rotates the shaft 110 at a high speed C + (number of revolutions / minute) (provided that the relationship of C << C + is satisfied), and performs centrifugal dehydration. As the switch 104g is pressed, the timer 104i starts. The timer 104i measures the time T2 (experimental value) required for the liquid impregnation rate of the mattresses 50 and 51 after washing to decrease from about 60% to about 10%. The control circuit 104h stops power supply from the power supply 104d to the electric motor 116 in response to the end of the time T2 measurement by the timer 104i.

  In the drying apparatus according to the second embodiment, the drying chamber 101 functions as a shield that prevents the liquid splashing radially from the mattresses 50 and 51 from coming out of the apparatus. The drying chamber 101 is provided with a drain duct (not shown) that drains the water on the floor surface to the outside of the drying chamber 101. Further, the check valves 114b and 115b are provided in the nozzles 114a and 115a of the first and second dry-air injection devices 114 and 115 so that liquids scattered from the mattresses 50 and 51 do not enter when the centrifugal dehydration is performed. deep.

  After the centrifugal dehydration is completed, the above-described drying process is executed by sequentially pressing the switch 104a and the switch 104b. Note that the time measured by the timer 104f started by the switch 104b is a time T3 (experimental value) required for substantially completely drying the mattresses 50 and 51 having the liquid impregnation rate of about 10% from the time T1. Change to The total time of the time T2 and the time T3 can be shorter than the time T1.

Hereinafter, only components different from the drying apparatus according to Embodiment 2 will be described. The same components as those in the drying apparatus according to Embodiment 2 are denoted by the same reference numerals, and redundant description is omitted.

  The rotating shaft 110 of the frame 103 is formed in a tubular shape. A plurality of holes are provided in the shaft 110 along the axial direction. The plurality of holes sprinkle the liquid supplied to the tubular shaft 110 in the centrifugal direction. As indicated by a broken line in FIG. 9, a water supply device 104 j is added to the operation unit 104. The water supply device 104j is stopped after sequentially supplying a predetermined amount of the cleaning liquid and the rinsing liquid to the tubular shaft 110 with the start.

  In response to pressing of the switch 104g, the electric motor 116 is started and the water supply device 104j is started. The cleaning liquid and the rinsing liquid sprayed to the inner surfaces 50b and 51b of the mattresses 50 and 51 from the plurality of holes provided in the shaft 110 pass through the mattresses 50 and 51 by the action of centrifugal force after adhering to the mattresses 50 and 51. The air scatters radially from the outer surfaces 50a and 51a and is discharged out of the apparatus through the drainage duct. The time measured by the timer 104i is set to the time T2 + obtained by adding the time required for supplying the cleaning liquid and the rinsing liquid by the water supply device to the time T2.

  After completion of washing, rinsing and centrifugal dehydration, the switches 104a and 104b are pressed in order to execute a drying process. The drying process is performed by changing the time measured by the timer 104f to T3 as in the case of the drying apparatus according to the second embodiment described above.
