<1. Configuration example of closed type cleaning device>
First, a configuration example of a closed cleaning apparatus according to an embodiment of the present invention will be described.
FIG. 1 is an explanatory view schematically showing an example of the schematic configuration of a closed cleaning apparatus according to this embodiment.

(overall structure)
The closed cleaning apparatus 100 described as an example in this embodiment is configured to clean an object to be cleaned using a cleaning liquid in a closed space. As the cleaning liquid, for example, a low boiling point cleaning liquid such as a bromine-based cleaning liquid, a chlorine-based cleaning liquid, or a fluorine-based cleaning liquid is used. In addition, various parts such as electronic parts or mechanical parts can be objects to be cleaned, for example. The object to be cleaned is cleaned with the cleaning liquid, for example, degreasing (removal of organic matter such as oil, flux, wax, etc.) and removal of inorganic matter (sand, stone, metal powder, etc.). It is assumed that the objects to be cleaned are transported and cleaned while being housed in a dedicated basket 1 .

In order to wash the object to be washed, the closed cleaning apparatus 100 is roughly divided into a closed container 10, a cleaning liquid filter 20, a cooler 30, a water separator 40, an accumulator 50, and a lid 60. , a moving mechanism unit 70, and a control unit 80.

(closed container)
The sealed container 10 is used to wash and dry the objects to be washed inside, and is formed in a substantially cylindrical shape with an open top and a bottomed bottom. The opening at the top of the container is sized to allow the basket 1 containing the objects to be washed to be taken in and out. Further, the opening at the top of the container is sealed with a lid body 60 which will be described later in detail, so that a sealed space is formed inside the closed container 10 . That is, the sealed container 10 is of a sealed structure type having a lid 60 covering the opening. In addition, the opening of the closed container 10 may be arranged on the side of the container instead of the upper part of the container.

Further, the sealed container 10 is configured such that each region of the immersion cleaning region Z1, the steam cleaning region Z2 and the drying region Z3 is formed in the container.

(Immersion cleaning area)
The immersion cleaning area Z1 is an area for immersing the object to be cleaned in the cleaning liquid 2 for liquid cleaning (primary cleaning). In order to form such an immersion cleaning area Z1, the sealed container 10 has a liquid cleaning tank 11 in the lower part of the inside, and the cleaning liquid 2 is stored in the liquid cleaning tank 11. As shown in FIG. That is, in the sealed container 10, the immersion cleaning area Z1 is formed by the liquid cleaning tank 11 that stores the cleaning liquid 2. As shown in FIG.
An ultrasonic vibrator 12 is installed on the bottom side of the liquid cleaning tank 11 , and the cleaning liquid 2 can be stirred by vibrating the ultrasonic vibrator 12 . Therefore, in the immersion cleaning area Z1, the cleaning efficiency is dramatically improved by the ultrasonic oscillator 12, so that the cleaning time can be greatly shortened.
A washing liquid filter 20 whose details will be described later is connected to the liquid washing tank 11 .

(Steam cleaning area)
The steam cleaning area Z2 is an area formed above the immersion cleaning area Z1, and is an area for cleaning (secondary cleaning) the object to be cleaned by spraying cleaning steam onto the object to be cleaned. In order to form such a vapor cleaning zone Z2, the closed container 10 has a vapor cleaning tank 13 above the liquid cleaning tank 11 and is formed on the side of the liquid cleaning tank 11 via a partition wall. It has a steam generation tank 14 .
The steam generation tank 14 stores the cleaning liquid 2 and is provided with a heater 15 for heating the cleaning liquid 2 to generate cleaning steam. In this embodiment, a heating coil is provided as the heater 15, but a resistance heating type heater may be provided. The heating coil is connected as a condenser to a refrigeration cycle (not shown) of cooler 30 . A cooling coil 17 as an evaporator is connected to the cooler 30 as will be described later. Therefore, by connecting the heating coil and the cooling coil 17 to the refrigerating cycle, efficient operation of the cooler 30 becomes possible.
The steam generation tank 14 is connected to the sealed container 10 via a pipe (hereinafter also referred to as a cleaning steam supply pipe) 14a for introducing the cleaning steam generated by heating the heater 15 into the steam cleaning tank 13. communicated with the inside. The pipe 14a also functions as an overflow port 14b for collecting the cleaning liquid 2 overflowing from the liquid cleaning tank 11. As shown in FIG.
With such a configuration, the cleaning steam generated from the steam generating tank 14 is introduced into the steam cleaning tank 13 and stays therein. That is, in the sealed container 10 , the steam cleaning area Z 2 is formed in the steam cleaning tank 13 due to the retention of the cleaning steam generated from the steam generating tank 14 in the steam cleaning tank 13 .

(dry area)
The drying zone Z3 is a zone formed above the steam cleaning zone Z2, and cools and condenses the cleaning steam to dry the atmosphere in the sealed container 10, thereby drying the object to be cleaned. area. In order to form such a drying zone Z3, the sealed container 10 has a drying tank 16 in the upper part thereof and a cooling coil 17 wound along the inner wall of the drying tank 16. As shown in FIG. The cooling coil 17 is connected to a cooler 30 whose details will be described later.
With such a configuration, the cleaning steam remaining in the steam cleaning zone Z2 is cooled by the cooling coil 17 and condensed when it rises to the location where the cooling coil 17 is installed. Therefore, the upper side of the steam line L, which is the upper end of the steam cleaning area Z2, becomes a dry atmosphere area without penetration of the cleaning steam. That is, in the sealed container 10, the cooling of the cooling coil 17 forms a dry zone Z3 above the steam cleaning zone Z2.
A condensate receiver 16 a is installed below the cooling coil 17 . The condensate receiver 16a is connected to a water separator 40, the details of which will be described later.

(washing liquid filter)
The cleaning liquid filter 20 filters the cleaning liquid 2 stored in the liquid cleaning tank 11 for reuse. For this purpose, the washing liquid filter 20 has a strainer 21, a pump 22, a filter 23 and a check valve (not shown) on a pipe connected to the bottom of the liquid washing tank 11 via a drain valve (not shown). And it is configured to return the cleaning liquid 2 after filtration into the liquid cleaning tank 11 .

(Cooler)
The cooler 30 is for cooling the drying zone Z3 by flowing a refrigerant in the pipe of the pipe material that constitutes the cooling coil 17 . Note that the cooler 30 may be any device as long as it realizes a refrigeration cycle (thermodynamic cycle) for cooling, and a device configured using a known technique can be used.

(water separator)
The water separator 40 separates the condensate accumulated in the condensate receiver 16 a into the cleaning liquid 2 and the water 3 and returns the separated cleaning liquid 2 to the liquid cleaning tank 11 . A discharge port 41 for the condensate collected in the condensate receiver 16 a is connected to the water separator 40 via a discharge pipe 42 and an inlet 43 . The water separator 40 includes a closed tank 44 as a main body and a plurality of baffle plates 46 that separate the cleaning liquid 2 and the water 3 according to the difference in specific gravity by forming a flow path 45 meandering in the vertical direction in the closed tank 44 . ) and A discharge port 47 for the cleaning liquid 2 of the water separator 40 is connected to the liquid cleaning tank 11 on the downstream side via a discharge pipe 48 .

(accumulator)
The accumulator 50 communicates with the sealed container 10 through a gas supply/discharge pipe 51, and is used to absorb pressure fluctuations in the sealed container 10 by taking gas accumulated in the sealed container 10 into and out of the sealed container 10. It is. Here, the gas is a gas obtained by vaporizing the atmosphere or the cleaning liquid 2 . To absorb pressure fluctuations, the accumulator 50 consists of a floating roof storage tank and comprises a lower container 52, a movable body 53 and a counterweight 54.
The lower container 52 is open at the top and stores an inert liquid 4 such as water that does not react with the gas at the bottom. A water level gauge 55 is provided on the outer wall of the lower container 52 so that the water level of the inert liquid 4 in the lower container 52 can be sensed from the outside. A drain pipe 56 a for discharging the inert liquid 4 and an open/close valve 56 b are connected to the lower container 52 .
The movable body 53 is formed in the shape of a lidded and bottomless container, is fitted from the opening of the lower container 52 , is arranged so as to cover the opening, and the bottomless side is immersed in the inert liquid 4 . As a result, the movable body 53 is floated and supported on the inert liquid 4 by the gas 5 accumulated in the space inside the movable body 53 . The space in the movable body 53 communicates with the gas supply/discharge pipe 51 so that gas can be taken in and out of the sealed container 10 .

The counterweight 54 has approximately the same weight as the movable body 53 and is arranged outside the lower container 52 while maintaining a state of equilibrium with the movable body 53 .
A connecting body 57 that connects the movable body 53 and the counterweight 54 is hooked on a rotating body 58 provided on the upper surface of a plate-like body 52a placed on the upper end of the opening of the lower container 52, and one end is movable. It is attached to body 53 and the other end is attached to counterweight 54 . Thus, the movable body 53 and the counterweight 54 are connected by the connecting body 57 guided by the rotating body 58 . For example, the rotating body 58 is preferably a pulley, and the connecting body 57 is preferably a wire or a rope.
At least one of the movable body 53 and the counterweight 54 may be attached with an adjusting member 59 for adjusting their weight balance. The adjustment member 59 is formed in, for example, a columnar shape or a rectangular parallelepiped shape, and the weight balance can be adjusted by the number of the adjustment members 59 to be attached.

When the accumulator 50 having such a configuration absorbs pressure fluctuations in the closed vessel 10, fluctuations and rises in the internal pressure inside the closed vessel 10 are prevented, and fluctuations in the steam line L are prevented. It is very suitable for improving the airtightness inside the container 10 .

(Lid body)
The lid 60 seals the opening of the sealed container 10 (that is, a loading/unloading port 10a for loading/unloading an object to be cleaned shown in FIG. 2 to be described later) to form a sealed space inside the sealed container 10. belongs to. For this purpose, the lid 60 is provided with an airtight member 60a along the periphery of the loading/unloading port 10a in contact with the lid 60 . As the airtight member 60a, for example, an O-ring made of an elastic material such as rubber is preferable.

Further, the lid 60 is provided so as to be openable and closable with respect to the loading/unloading port 10a. Here, the mechanism for opening and closing the lid body 60 will be described in more detail.
FIG. 2 is an explanatory view schematically showing a configuration example of the lid 60, the first moving mechanism 61 and the second moving mechanism 62 in the closed cleaning device 100 according to this embodiment.

The lid 60 has a first movement mechanism 61 for moving the lid 60 in a first direction and a second movement mechanism 61 for moving in a second direction orthogonal to the first direction in order to open and close the loading/unloading port 10a. It is supported by two moving mechanisms 62 and . Here, when the loading/unloading port 10a is located on the upper surface (ceiling portion) of the sealed container 10, the "first direction" refers to a direction orthogonal to the vertical direction, and the "second direction" Refers to the vertical downward direction. In this embodiment, the case where the loading/unloading port 10a is formed on the upper surface of the closed container 10 is taken as an example, but the loading/unloading port 10a may be provided on the side surface of the closed container 10. In that case, The "first direction" refers to the vertical direction, and the "second direction" refers to the direction orthogonal to the vertical direction.

The first moving mechanism 61 is for horizontally sliding the lid 60 to open and close it. 61a, and a slider 61b that slides in engagement with each guide rail 61a. With such a configuration, the lid body 60 smoothly moves horizontally along the guide rails 61a. The lid 60 can be opened and closed manually or automatically. When manually opening and closing, the handle 63 is held and the cover 60 is slid. In the case of automatic opening and closing, an air cylinder 64 for opening and closing the lid which expands and contracts in the horizontal direction is attached to the lid 60 , and the expansion and contraction of the air cylinder 64 automatically opens and closes the lid 60 . In any case, since the first moving mechanism 61 makes the sliding movement in the horizontal direction the main opening/closing direction of the lid body 60, compared to the opening/closing direction using a hinge mechanism, for example, when sealing It becomes possible to easily improve the pressure resistance, and as a result, it is very suitable for improving the sealing performance of the sealed container 10 .

However, if the first moving mechanism 61 only slides the lid 60, the lid 60 interferes with the top plate 10b of the sealed container 10, and the operability for opening and closing is impaired. There is a risk. Therefore, the lid body 60 is supported by the second moving mechanism 62 in addition to the first moving mechanism 61 .

The second moving mechanism 62 is for supporting the lid body 60 so as to be movable in the vertical direction. 62a), and a spring portion 62d arranged on the outer circumference of the shaft portion 62a. The shaft portion 62a passes through an opening (not shown) formed in the connecting plate 62b, has its upper end fixed to the lower surface of the handle 63, has its lower end fixed to the upper surface of the lid 60, and is fixed to the lower surface of the connecting plate 62b. It is supported by a bearing portion 62c attached to the . The spring portion 62d is, for example, a compression spring, is mounted between the lower surface of the handle 63 and the upper surface of the connecting plate 62b, and biases the lid body 60 in the second direction. With such a configuration, the lid body 60 maintains a state of being biased in the second direction (that is, the direction away from the top plate 10b of the closed container 10) by the spring portion 62d. Therefore, when the lid 60 is opened and closed, the lid 60 does not interfere with the top plate 10b of the closed container 10 or the like.

In addition, it is preferable that the shaft portion 62 a that constitutes the second moving mechanism 62 is configured integrally with the handle 63 . This is because the simplification and space saving of the configuration of the second moving mechanism 62 can be realized.

A lid pressing portion 65 is provided in the vicinity of the lid 60 supported by the first moving mechanism 61 and the second moving mechanism 62 as described above. The lid pressing part 65 presses the four corners of the closed lid 60 around the loading/unloading port 10a with a predetermined pressure to bring the closed container 10 into a sealed state, and releases the pressing force to close the closed container 10. It should be closed. By providing the lid pressing portion 65, even when the lid 60 is supported by the second moving mechanism 62 and urged in the second direction, the sealed container 10 can be sealed. . As the lid pressing portion 65, for example, a manually operated toggle clamp, an automatically operated air cylinder, or the like may be used. The predetermined pressure with which the lid pressing portion 65 presses the lid 60 is, for example, 0.3 MPa to 0.6 MPa.

Moreover, it is preferable that the lid 60 is provided with a viewing window 60b for observing the inside of the closed container 10 . The viewing window 60b is composed of a window hole 60c provided in the central portion of the lid 60 and pressure-resistant glass 60d airtightly fixed to the window hole 60c.

It is for moving to For this purpose, the moving mechanism section 70 includes an arm 71 for supporting the basket 1 containing the objects to be washed, a feed mechanism 72 such as a feed screw for vertically moving the arm 71, and a drive source 73 for operating the feed mechanism 72. and The lifting stroke of the arm 71 by the operation of the feeding mechanism 72 is determined based on the positions of the regions Z1 to Z3 so that the basket 1 can be moved and arranged in the regions Z1 to Z3. As the drive source 73 for operating the feeding mechanism 72, for example, an electric motor is used. Examples of the electric motor include a stepping motor, an induction motor with a brake, a reversible motor with a brake, etc., but it is particularly preferable to use a servomotor, which has excellent controllability of operating position, speed, and the like.

In the moving mechanism section 70 having such a configuration, the arm 71 is arranged inside the sealed container 10 . Further, the feeding mechanism 72 is housed in a moving mechanism housing space 74 that is airtightly connected to the sealed container 10 . However, it is assumed that the drive source 73 is arranged in a separate space isolated from the space inside the sealed container 10 and the moving mechanism part housing space 74 .

(control part)
The control unit 80 controls the operations of the ultrasonic vibrator 12 of the liquid cleaning tank 11, the heater 15 of the steam generation tank 14, the drive source 73 of the moving mechanism unit 70, the cooler 30, the air cylinder, and the like. It is. Such a control unit 80 can be configured using a computer that executes a predetermined control program, or a device (for example, a programmable logic controller) that has equivalent functions. That is, the control unit 80 is provided with hardware resources as a computer, and by executing a predetermined control program, the control program (software) and the hardware resources cooperate to operate the closed cleaning apparatus. 100 is configured to control the operation of each unit.

Also, the control unit 80 is configured to have the functions described below.
FIG. 3 is a block diagram showing a functional configuration example of the controller 80 in the closed cleaning apparatus 100 according to this embodiment.
The control unit 80 has at least functions as an operation instruction unit 81 , a position recognition unit 82 , a memory unit 83 and an operation unit 84 .

Of these, at least the parts 10 to 40 and 60 to 80 excluding the accumulator 50 are accommodated in the housing of the closed cleaning device 100. As shown in FIG. However, the configuration is not necessarily limited to this. For example, the control unit 80 may be installed separately from the closed cleaning apparatus 100 as long as it can communicate with the closed cleaning apparatus 100. .

<2. Example of processing operation in closed type cleaning equipment>
Next, an example of a processing operation in the closed cleaning apparatus 100 having the above configuration will be described.

(Basic processing operation example)
Here, first, an example of a basic processing operation in the closed cleaning apparatus 100 will be described.
FIG. 4 is a flow chart showing the procedure of a basic processing operation example in the closed cleaning apparatus 100 according to this embodiment.

In the closed cleaning apparatus 100 according to the present embodiment, when cleaning the object to be cleaned, there are a preparation process (step 101, hereinafter step is abbreviated as "S"), a primary cleaning process (S102), and a secondary cleaning process (S103). , the drying step (S104) and the removing step (S105). In addition, in the following description, the operation of each part constituting the closed cleaning apparatus 100 is mainly controlled by the control part 80 .

(Preparation process)
In the preparation step ( S<b>101 ), the cleaning liquid 2 is stored in the liquid cleaning tank 11 and the steam generation tank 14 in the closed container 10 . Furthermore, the cooler 30 is operated to cool the cooling coil 17 and heat the heater 15 .
Then, an immersion cleaning area Z1 is formed in the liquid cleaning tank 11. As shown in FIG.
In addition, the cooling coil 17 cools the atmosphere in the drying chamber 16 in the closed container 10, and the drying zone Z3 is formed in the drying chamber 16 by the cooling and aggregation of the atmosphere.
Also, the heating of the heater 15 generates cleaning steam from the steam generation tank 14, which is introduced into the steam cleaning tank 13 through the cleaning steam supply pipe 14a. However, the drying zone Z3 is cooled by the cooling coil 17 . Therefore, the cleaning steam stays in the steam cleaning tank 13, thereby forming a steam cleaning zone Z2 between the immersion cleaning zone Z1 and the drying zone Z3. Furthermore, a steam line L is formed between the drying zone Z3 and the steam cleaning zone Z2. When the vapor line L is formed, the cooling and condensation in the drying zone Z3 are stabilized, and the airtightness of the closed vessel 10 is stabilized. The temperature of the cleaning steam is maintained at the boiling point of the cleaning liquid by continuously supplying the cleaning steam from the steam generation tank 14 .

After the immersion cleaning zone Z1, the steam cleaning zone Z2 and the drying zone Z3 are formed, the arm of the moving mechanism section 70 moves the basket 1 containing the objects to be cleaned through the carry-in/out port 10a with the cover 60 open. 71 to support. Thereafter, the first moving mechanism 61 moves the lid 60 in the first direction, and the lid pressing portion 65 and the second moving mechanism 62 move the lid 60 in the second direction. The outlet 10a is sealed with a lid 60. FIG. Thereby, the sealed container 10 is brought into a sealed state.

(Primary cleaning process)
In the subsequent primary cleaning step ( S<b>102 ), the moving mechanism 70 lowers the basket 1 to reach the cleaning liquid 2 in the liquid cleaning tank 11 . As a result, the objects to be cleaned housed in the basket 1 are immersed in the cleaning liquid 2 in the liquid cleaning tank. Then, while the object to be cleaned is immersed in the cleaning liquid 2, the ultrasonic vibrator 12 is operated to perform liquid cleaning on the object to be cleaned. In other words, primary cleaning is performed on the object to be cleaned in the immersion cleaning zone Z1. At this time, the cleaning liquid 2 in the liquid cleaning tank 11 is agitated by the ultrasonic vibrator 12, so the primary cleaning can be completed in a short time. The cleaning liquid 2 in the liquid cleaning tank 11 can be kept clean by filtering using the cleaning liquid filter 20 .

(Secondary washing process)
After the primary cleaning is finished, in the subsequent secondary cleaning step (S103), the basket 1 is lifted up to the steam cleaning zone Z2 by the moving mechanism 70, and the object to be cleaned accommodated in the basket 1 is steam cleaned. . In other words, the object to be cleaned is subjected to secondary cleaning in the steam cleaning zone Z2. In the secondary cleaning, cleaning steam is sprayed to clean the object to be cleaned. As the cleaning steam, the steam of the cleaning liquid 2 generated from the steam generation tank 14 is used.

(Drying process)
After the secondary washing is finished, in the subsequent drying step (S104), the movement mechanism 70 moves the basket 1 up to the drying zone Z3, and the objects to be washed stored in the basket 1 are dried. That is, the object to be washed is dried in the drying zone Z3. In the drying zone Z3, the liquid such as the cleaning liquid adhering to the surface of the object to be cleaned evaporates due to heat accumulated in the basket 1 and the object to be cleaned. The evaporated liquid diffuses and becomes condensate on the surface of the cooling coil 17 or the inner surface of the side wall in the drying tank 16 and is collected in the condensate receiver 16a.

The condensate collected in the condensate receiver 16a is introduced into the flow path 45 of the water separator 40 through the discharge pipe 42 from the discharge port 41 of the condensate receiver 16a. The flow path 45 meanders vertically due to the baffle plate 46 . Therefore, in the channel 45 , the water 3 stays in the upper part of the channel 45 due to the difference in specific gravity between the cleaning liquid 2 and the water 3 . Thereby, the washing liquid 2 and the water 3 can be separated from the condensate. Moisture remaining in the upstream portion of the flow path 45 is discharged by opening and closing the valve.

The cleaning liquid 2 overflowing the baffle plate 46 on the downstream side is returned to the liquid cleaning tank 11 . When the cleaning liquid 2 overflows from the liquid cleaning tank 11 due to the reflux of the cleaning liquid 2, the overflowed cleaning liquid is collected in the steam generating tank 14 through the overflow port 8a. The cleaning liquid 2 collected in the steam generation tank 14 is again supplied to the steam cleaning zone Z2 as cleaning steam, and is repeatedly used as cleaning steam.

(Pressure fluctuation absorption treatment)
By the way, in the preparation step (S101) described above, since the cleaning liquid 2 is heated and the cover 60 is opened and closed, the gas pressure in the drying tank 16 of the sealed container 10 fluctuates. Further, in the primary cleaning step (S102) described above, the cleaning liquid 2 is supplied from the water separator 40, and the supply amount fluctuates, so the gas pressure in the drying tank 16 of the closed container 10 constantly fluctuates. . In addition, in the secondary cleaning step (S103) described above, since the supply of steam from the steam generation tank 14 to the closed container 10 continues, the amount of steam in the closed container 10 fluctuates, and the cooling coil 17 causes the steam to rise. In the drying tank 16 of the closed container 10, the gas pressure in the drying tank 16 constantly fluctuates. Further, in the drying step (S104) described above, the gas is condensed by the cooling coil 17 in the drying tank 16, so the gas pressure in the sealed container 10 constantly fluctuates. In this manner, the internal pressure of the sealed container 10 constantly fluctuates during the primary cleaning step (S102), the secondary cleaning step (S103), and the drying step (S104) described above.

When the gas pressure in the closed container 10 reaches a certain level or higher, part of the gas flows through the gas supply/discharge pipe 51 to the accumulator 50, so the gas pressure in the closed container 10 decreases. The gas flowing into the accumulator 50 pushes up the movable body 53 to balance it. Conversely, when the gas pressure in the closed container 10 becomes less than a certain level, the movable body 53 descends to balance, and the gas in the movable body 53 flows into the closed container 10 through the gas supply/exhaust pipe 51. The gas pressure inside the sealed container 10 is increased. As a result, during steam cleaning, the pressure inside the closed container 10 is always adjusted to be constant regardless of the amount of steam supplied inside the closed container 10, and the gas pressure inside the closed container 10 does not rise excessively. . Therefore, it is possible to prevent the cleaning liquid 2 or its vapor from leaking to the outside by breaking the airtightness of the lid 60 of the sealed container 10 .

Moreover, a counterweight 54 is connected to the movable body 53 of the accumulator 50 . The counterweight 54 has a weight that maintains a state of equilibrium with the movable body 53 , more specifically, has approximately the same weight as the movable body 53 . Therefore, by interlocking the movable body 53 and the counterweight 54 , the dead weight of the movable body 81 can be offset when the movable body 53 moves up and down. By offsetting the weight of the movable body 53 with the counterweight 54, the reactivity when the movable body 53 moves up and down can be improved.
In addition, when the adjusting member 59 is attached, the weight balance between the movable body 53 and the counterweight 54 can be adjusted by the adjusting member 59 . By adjusting the weight balance, it becomes possible to change the reactivity when the movable body 53 moves up and down as necessary.

(Extraction process)
After the drying step (S104) is completed, the pressing force of the lid pressing portion 65 on the lid 60 is released in the subsequent removing step (S105). As a result, the lid body 60 is biased by the second moving mechanism 62 and comes into a non-contact state with respect to the loading/unloading port 10a. Then, the cover body 60 in the non-contact state is moved by the first moving mechanism 61 without interfering with it in the sliding direction, thereby opening the loading/unloading port 10a. By opening the loading/unloading port 10a with the cover 60 in the open state in this way, it is possible to carry out the washed objects stored in the basket 1 to the outside through the loading/unloading port 10a.

(Example of control processing operation)
Next, an example of a processing operation when the controller 80 controls the movement of the object to be cleaned when the closed cleaning apparatus 100 performs the series of processing operations described above will be described in more detail.
FIG. 5 is a flowchart showing a procedure of an example of processing operation when the control unit 80 of the closed cleaning apparatus 100 according to this embodiment controls movement of the object to be cleaned.

When an object to be cleaned is stored in the basket 1 and carried into the sealed container 10 together with the basket 1, for example, when a predetermined operation to start cleaning is performed on the operation unit 84 (S201), first, the reference position is reached. The operation instructing section 81 gives an operation instruction to the driving source 73 of the moving mechanism section 70 so as to perform an initialization operation for recognizing the (home position). Then, when the position recognition unit 82 recognizes that it is positioned at the reference position (S202), the initialization operation is terminated.

After the initialization operation, the operation instructing section 81 gives an operation instruction to the driving source 73 of the moving mechanism section 70 so as to move the basket 1 from the reference position to the immersion cleaning area Z1 (S203). At this time, the operation instructing section 81 reads out information about the movement speed to the immersion cleaning area Z1 from the memory section 83, and gives an operation instruction to the drive source 73 so as to operate at the movement speed specified by the information.

Then, when the position recognition unit 82 recognizes that the basket 1 has moved to the immersion cleaning area Z1, the operation instructing unit 81, based on the readout information from the memory unit 83, until the preset primary cleaning time elapses ( S204), the basket 1 is positioned in the immersion cleaning zone Z1. As a result, the objects to be cleaned stored in the basket 1 are subjected to the primary cleaning step (S102) in which the primary cleaning is performed in the immersion cleaning area Z1.

After the primary cleaning time has elapsed, the operation instruction unit 81 gives an operation instruction to the driving source 73 of the moving mechanism unit 70 so as to move the basket 1 from the immersion cleaning area Z1 to the steam cleaning area Z2 (S205). At this time, the operation instructing unit 81 reads out information about the moving speed up to the steam cleaning area Z2 from the memory unit 83, and gives an operation instruction to the driving source 73 so as to operate at the moving speed specified by the information.

When the position recognition unit 82 recognizes that the basket 1 has moved to the steam cleaning area Z2, the operation instructing unit 81, based on the information read from the memory unit 83, waits until the preset secondary cleaning time elapses. (S206), the basket 1 is positioned in the steam cleaning zone Z2. As a result, the objects to be cleaned stored in the basket 1 are subjected to the secondary cleaning step (S103) in which secondary cleaning is performed in the steam cleaning area Z2.

After the secondary cleaning time has elapsed, the operation instruction unit 81 gives an operation instruction to the driving source 73 of the moving mechanism unit 70 so as to move the basket 1 from the steam cleaning area Z2 to the drying area Z3 (S207). At this time, the operation instructing unit 81 reads out information about the moving speed up to the drying zone Z3 from the memory unit 83 and gives an operation instruction to the driving source 73 so as to operate at the moving speed specified by the information.

Then, when the position recognition unit 82 recognizes that the basket 1 has moved to the drying zone Z3, the operation instructing unit 81 waits until the preset drying time elapses based on the information read from the memory unit 83 (S208). , the basket 1 is positioned in the drying zone Z3. As a result, the objects to be washed stored in the basket 1 are subjected to the drying step (S104) in which the objects are dried in the drying zone Z3.

After the drying time has elapsed, the operation instructing section 81 gives an operation instruction to the driving source 73 of the moving mechanism section 70 so as to move the basket 1 from the drying zone Z3 to the reference position (S209). As a result, a series of cleaning processes for the items to be cleaned stored in the basket 1 is completed, and the cleaned items to be cleaned can be carried out to the outside through the carry-in/out port 10a through the removal step (S105). It becomes possible.

(Setting movement conditions)
Incidentally, in the series of control processing operation examples described above, the operation instructing section 81 gives an operation instruction to the drive source 73 so as to operate at the moving speed specified by the information read from the memory section 83 . At this time, in the memory unit 83, from the reference position to the immersion cleaning area Z1, from the immersion cleaning area Z1 to the steam cleaning area Z2, from the steam cleaning area Z2 to the drying area Z3, from the drying area Z3 to the reference It is conceivable to store and hold information about the moving speed individually for each of the distances up to the position. Information stored in the memory unit 83 can be appropriately set through the operation of the operation unit 84 . Therefore, if the memory unit 83 is capable of storing individual information, the control unit 80 will control the distance between the areas Z1 to Z3 (including between the reference positions) for the basket 1 containing the objects to be washed. ) can be individually set for each of the regions Z1 to Z3. The term "moving speed" as used herein refers to the speed in a steady state excluding the period of acceleration and deceleration.

Thus, in the closed cleaning apparatus 100 having the immersion cleaning zone Z1, the steam cleaning zone Z2 and the drying zone Z3 in the closed container 10, the speed at which the object to be cleaned moves between the zones Z1 to Z3 is If it is possible to individually set each of the zones Z1 to Z3, it becomes possible, for example, to make the movement speed different between the zones Z1 to Z3. In other words, by individually setting the moving speed for each of the zones Z1 to Z3, the degree of freedom in controlling the operation of the moving mechanism section 70 when performing the cleaning process on the object to be cleaned is improved. If the degree of freedom of operation control is improved, it will be possible to optimize the cleaning process for the object to be cleaned.

Specifically, the operation control in the following aspects is given as an example. For example, the controller 80 sets the speed of movement from the steam cleaning zone Z2 to the drying zone Z3 faster than the speed of movement between other zones. The other areas referred to here correspond to the area from the reference position to the immersion cleaning area Z1, the area from the immersion cleaning area Z1 to the steam cleaning area Z2, and the area from the drying area Z3 to the reference position. The moving speed between the other zones may be the same speed that is slower than the moving speed from the steam cleaning zone Z2 to the drying zone Z3. good too.

In this way, when the moving speed from the steam cleaning zone Z2 to the drying zone Z3 is made faster than the moving speed between the other zones, it is possible to suppress the occurrence of cleaning stains on the object to be cleaned. As described above, when the object to be cleaned is washed by combining the primary cleaning and the secondary cleaning, the cleaning effect can be enhanced by utilizing the aggregation of the cleaning steam in the secondary cleaning. If agglomerates remain on the surface of the object, washing stains may occur. On the other hand, if the speed of movement to the drying zone Z3 is increased, the object to be washed immediately moves to the drying zone Z3 after the secondary cleaning, so that the object to be washed is dried efficiently. As a result, it is possible to prevent the aggregates from remaining as washing stains on the surface of the object to be washed.

In order to perform the above operation control, it is preferable that the driving source 73 of the moving mechanism section 70 is an electric motor. In particular, it is preferable to use a servomotor, which has excellent controllability of operating position, speed, and the like, as the motor. With this configuration, it is possible to easily control the speed when moving the object to be cleaned, and to respond flexibly and accurately to changes in the moving speed.

When a motor is used as the driving source 73 of the movement mechanism 70, the motor is arranged in a separate space isolated from the space inside the sealed container 10 and the movement mechanism housing space 74. If it is arranged in a separate space, even if there is a gas containing an organic solvent with degreasing power in the space inside the sealed container 10, the components contained in the gas will not adversely affect the printed circuit board of the motor. This is because it becomes possible to prevent

<3. Effect of the present embodiment>
According to this embodiment, one or more of the following effects can be obtained.

(a) According to the closed type cleaning apparatus 100 according to the present embodiment, the immersion cleaning area Z1, the steam cleaning area Z2 and the drying area Z3 are formed in the closed container 10, and the primary cleaning in the immersion cleaning area Z1 and the steam Since the secondary cleaning in the cleaning zone Z2 and the drying process in the drying zone Z3 are combined to clean the object to be cleaned, an excellent cleaning effect can be obtained. Moreover, even in that case, since the pressure in the sealed container 10 is stabilized by the accumulator 50, it is possible to effectively prevent the cleaning liquid 2 from leaking to the outside. Contamination, an increase in consumption of the cleaning liquid 2, and the like can be suppressed. In particular, when a brominated cleaning liquid is used as the cleaning liquid 2, the effect of reducing CO ₂ is extremely high, so contamination of the external environment can be more effectively suppressed.

(b) In the present embodiment, in the sealed cleaning apparatus 100 having the immersion cleaning zone Z1, the steam cleaning zone Z2 and the drying zone Z3 in the closed container 10, when the object to be cleaned moves between the zones Z1 to Z3 can be individually set for each of the zones Z1 to Z3. Therefore, since the degree of freedom in controlling the operation of the moving mechanism 70 when performing the cleaning process on the object to be cleaned is improved, it is possible to prevent, for example, the deterioration of the cleaning effect. Further optimization of the cleaning process for the object to be cleaned can be achieved.

(c) In this embodiment, in controlling the movement of the object to be cleaned, the speed of movement from the steam cleaning zone Z2 to the drying zone Z3 is made faster than the speed of movement between other zones. Therefore, since the object to be washed immediately moves to the drying zone Z3 after the secondary washing, the drying process is efficiently performed on the object to be washed, and the aggregates remain as cleaning stains on the surface of the object to be washed. You will be able to restrain yourself from doing it. In other words, it is possible to prevent cleaning stains from remaining on the surface of the object to be cleaned, thereby further optimizing the cleaning process for the object to be cleaned.

(d) In the present embodiment, the moving mechanism section 70 has a motor as the drive source 73 for moving the object to be cleaned, so the speed can be easily controlled when moving the object to be cleaned. It is possible to respond flexibly and accurately to variable movement speeds.

(e) In this embodiment, since the motor as the drive source 73 is arranged in a separate space isolated from the space inside the closed container 10, an organic solvent having a degreasing power is added to the space inside the closed container 10 or the like. Even if the containing gas is present, it is possible to prevent the components contained in the gas from adversely affecting the printed circuit board of the motor or the like.

(f) In this embodiment, the accumulator 50 has a movable body 53 and a counterweight 54, and the counterweight 54 has a weight that keeps the movable body 53 and a balanced state. Therefore, since the weight of the movable body 53 is offset, the responsiveness when the movable body 53 moves can be improved, which is suitable for enhancing the sealing performance in the sealed container 10 .

(g) As described in this embodiment, if the adjustment member 59 is attached to at least one of the movable body 53 and the counterweight 54, the weight balance between the movable body 53 and the counterweight 54 can be adjusted. . In other words, by using the adjusting member 59, it is possible to finely adjust the weight balance between the movable body 53 and the counterweight 54, and it is possible to increase the reactivity of the movable body 53 reliably.

(h) In this embodiment, since the movable body 53 is formed in the shape of a container with a lid and without a bottom, even if a large amount of gas flows out from the sealed container 10 and the movable body 53 is pressurized unexpectedly, Even if there is, the lower side of the movable body 53 is exposed from the liquid surface and functions as a safety valve for releasing the pressure.

(i) In this embodiment, the lid body 60 is supported by the first moving mechanism 61 and the second moving mechanism 62 . Since the lid 60 is supported by the first moving mechanism 61 in this manner, the lid 60 transitions between the open state and the closed state by sliding in the first direction. Therefore, compared to a lid structure that opens and closes using a hinge mechanism, for example, it is possible to easily improve the pressure resistance, and it is suitable for enhancing the sealing performance of the closed container 10 . Moreover, since the lid body 60 is supported not only by the first moving mechanism 61 but also by the second moving mechanism 62, the lid body 60 can be separated from the top plate 10b when sliding in the first direction. It can be maintained and good operability can be ensured.

(j) In the present embodiment, since the second moving mechanism 62 is integrated with the handle 63, the configuration for opening and closing the lid 60 can be simplified.

<4. Other Embodiments>
Next, a closed cleaning device according to another embodiment of the present invention will be described. However, differences from the above-described embodiment will be mainly described here.

(Configuration example)
FIG. 6 is an explanatory diagram schematically showing a configuration example of a main part of a closed cleaning apparatus according to another embodiment.

The closed-type cleaning device 100 described here as an example includes a cleaning liquid ejection part 90 that ejects cleaning liquid into the space inside the closed container 10 in a shower-like manner. As the cleaning liquid ejected from the cleaning liquid ejecting part 90, the same kind of cleaning liquid as the cleaning liquid 2 stored in the liquid cleaning tank 11 or the steam generating tank 14 is used. In order to eject such a cleaning liquid, it is assumed that the cleaning liquid ejection section 90 is connected to a cleaning liquid supply section (not shown). The cleaning liquid supply unit may be newly provided in addition to the configuration described in the above embodiment, or may utilize the configuration described above, such as the cleaning liquid filter 20 or the water separator 40. There may be.

For example, the cleaning liquid ejection part 90 can be configured to eject the cleaning liquid toward the object to be cleaned in the sealed container 10, as shown in FIG. 6(a). Specifically, the cleaning liquid ejection part 90 is configured using a shower head that ejects the cleaning liquid. Then, the shower head is arranged so as to jet the cleaning liquid toward the object to be cleaned housed in the basket 1 located in the steam cleaning zone Z2. With the cleaning liquid ejection part 90 having such a configuration, the cleaning liquid is ejected toward the object to be cleaned in the form of a shower. It is possible to efficiently wash against. Furthermore, it becomes possible to cool the object to be cleaned by jetting the cleaning liquid.

Further, for example, the cleaning liquid ejecting part 90 can be configured to eject the cleaning liquid toward the inner wall surface of the sealed container 10, as shown in FIG. 6(b). Specifically, the cleaning liquid ejection part 90 is configured using a shower head that ejects the cleaning liquid. Then, the shower head is arranged so as to jet the cleaning liquid toward the inner wall surface of the steam cleaning area Z2 in the closed container 10 . With the cleaning liquid jetting part 90 having such a configuration, the cleaning liquid is jetted toward the inner wall surface of the sealed container 10 in the form of a shower. becomes possible. Furthermore, it is also possible to remove stains on the inner wall surface of the sealed container 10 by jetting the cleaning liquid.

Further, for example, if the cooler 30 uses the cleaning liquid as the coolant to flow through the cooling coil 17, the cleaning liquid jetting part 90 is provided at a predetermined position (for example, the lowest stage) in the cooling coil 17, as shown in FIG. 6(c). ) can be configured by utilizing the opening 17a provided in the portion of FIG. Specifically, the cleaning liquid is jetted from the opening 17 a of the cooling coil 17 toward the object to be cleaned or the inner wall surface of the sealed container 10 . With the cleaning liquid jetting section 90 having such a configuration, the cleaning liquid can be jetted without requiring a shower head or the like, so the configuration for jetting the cleaning liquid can be prevented from becoming complicated.

(Processing operation example)
The closed type cleaning apparatus 100 having such a configuration can perform the processing operations described below.

For example, in the case of jetting the cleaning liquid toward the object to be cleaned, after the secondary cleaning with cleaning steam in the secondary cleaning step (S103), before the drying treatment in the drying step (S104), the cleaning liquid The cleaning liquid is ejected from the ejection part 90 to clean the object to be cleaned. After the primary cleaning in the primary cleaning step (S102) and before performing the secondary cleaning in the secondary cleaning step (S103), the cleaning liquid jetting portion 90 jets the cleaning liquid to clean the object to be cleaned. can be Furthermore, after the primary cleaning in the primary cleaning step (S102), instead of the secondary cleaning step (S103) (that is, without performing the secondary cleaning with cleaning steam), the cleaning liquid is ejected from the cleaning liquid ejection part 90. The object to be washed may be washed by

Further, for example, when the cleaning liquid is jetted toward the inner wall surface of the closed container 10, after the secondary cleaning with cleaning steam in the secondary cleaning step (S103), the drying process in the drying step (S104). , the cleaning liquid is ejected from the cleaning liquid ejection part 90 to clean and cool the inner wall surface of the sealed container 10 .

As described above, in the closed type cleaning apparatus 100 according to the present embodiment, secondary cleaning (that is, so-called vapor cleaning) by cleaning steam performed by moving the object to be cleaned to the steam cleaning area Z2 and the cleaning liquid ejection part 90 are It is possible to selectively perform cleaning with jetted cleaning liquid (that is, so-called shower cleaning). The selection here includes selection of either vapor cleaning or shower cleaning, and selection of the order of execution when performing both of them. Such selection may be made based on information set in the memory section 83 .

That is, in the closed cleaning apparatus 100 according to the present embodiment, vapor cleaning and shower cleaning can be selectively performed according to preset settings. Therefore, for example, it is possible to switch between vapor cleaning and shower cleaning according to the object to be cleaned, and an improvement in cleaning effect can be expected due to a highly flexible setting.

(effect)
According to this embodiment, one or more of the following effects can be obtained.

(k) In the present embodiment, the cleaning liquid jetting part 90 for jetting the cleaning liquid into the space inside the sealed container 10 in a shower-like manner is provided, so shower cleaning can be performed using the cleaning liquid jetting part 90.

(l) As described in the present embodiment, if the cleaning liquid ejecting part 90 is configured to eject the cleaning liquid toward the object to be cleaned, it becomes possible to wash away, for example, foreign matter adhering to the surface of the object to be cleaned. , it becomes possible to efficiently wash the object to be washed. Furthermore, it becomes possible to cool the object to be cleaned by jetting the cleaning liquid. Therefore, it is very suitable for optimizing the cleaning process for the object to be cleaned.

(m) As described in the present embodiment, if the cleaning liquid ejection part 90 is configured to eject the cleaning liquid toward the inner wall surface of the sealed container 10, the temperature of the closed container 10, which has been heated by the influence of the steam for cleaning, can be reduced. It becomes possible to cool the inner wall surface. Furthermore, it is also possible to remove stains on the inner wall surface of the sealed container 10 by jetting the cleaning liquid. Therefore, it is very suitable for optimizing the cleaning process for the object to be cleaned.

(n) In the present embodiment, secondary cleaning (vapor cleaning) by cleaning steam performed by moving the cleaning object to the steam cleaning zone Z2 (vapor cleaning) and cleaning (shower cleaning) by the cleaning liquid ejected by the cleaning liquid ejection part 90 are performed. , can be done selectively. Therefore, for example, it is possible to switch between vapor cleaning and shower cleaning depending on the object to be cleaned. Further optimization of cleaning treatment for objects can be achieved.

<5. Variation>
Although the embodiments of the present invention have been specifically described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention.

For example, in the above-described embodiment, the control unit 80 mainly sets the moving speed such that the moving speed from the steam cleaning zone Z2 to the drying zone Z3 is faster than the moving speed between other zones. However, the present invention is not limited to this. In other words, the moving speed between the zones Z1 to Z3 may be set individually for each zone Z1 to Z3. It is possible to optimize the cleaning process for

For example, in the above-described embodiment, the case where shower cleaning can be handled in addition to vapor cleaning has been described, but the present invention is not limited to this, and the case where only vapor cleaning is compatible. You can also get a good cleaning effect.

Further, for example, in each of the above-described embodiments, a single-tank closed type cleaning apparatus has been described, but a two-tank type or a multi-tank type having a greater number of cleaning tanks may also be used.

Further, for example, in each of the above-described embodiments, the case where the loading/unloading port is formed in the upper portion (ceiling portion) of the airtight container has been described, but it may be formed in the side portion.
