Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to a drying device for parts used in optical equipment, electric equipment, automobiles and the like.

[0002]

[Prior art]

 Conventionally, CFCs have been used to dry these types of parts, especially metal parts, but their use is being regulated because they destroy the ozone layer, and chlorine-based solvents also cause groundwater pollution. The use of chlorine-based solvents is being regulated because they are easy and the work environment is adversely affected. Moreover, these cleaning agents have a problem that they are not suitable for cleaning rubber and plastic.

[0003]

[Problems to be solved by the device]

 Therefore, hydrocarbon-based cleaning agents are being used. However, this cleaning agent has a problem that it takes time to dry after cleaning. Therefore, it is conceivable to apply an air flow to the object to be dried to dry it, but if only the air flow is applied to the object to be cleaned, the drying of the part not exposed to the air flow will be delayed. . An object of the present invention is to provide a drying device without such a problem.

[0004]

[Means for Solving the Problems]

 In order to achieve such an object of the present invention, the drying apparatus according to claim 1 is provided with an air-permeable shelves for placing objects to be washed in a drying chamber in which an air flow from the upper side to the lower side is generated. A rotary air ejector having a plurality of air ejection nozzles is provided above the object to be cleaned placed on the object-to-be-cleaned shelf.

According to a second aspect of the present invention, the drying device is characterized in that the mounting angles of the plurality of air ejection nozzles are adjustable with respect to the rotary air ejector main body constituting the rotary air ejector.

[0006]

[Action]

 In the drying device according to claim 1 having the above-mentioned structure, the air flow from the upper side to the lower side is disturbed by the flow of the air ejected from the plurality of air ejection nozzles of the rotary air ejector. An object to be cleaned is efficiently dried by applying an air flow.

In the drying device according to the second aspect of the invention, since the attachment angle of the air ejection nozzle is automatically adjusted, the air flow can be adjusted according to the shape of the object to be cleaned and the like.

[0008]

【Example】

 The present invention will be described with reference to an embodiment shown in the drawings. In the drawing, 1 is a drying chamber in which an air flow from the upper side to the lower side is generated, 2 is a breathable object placing rack provided at the lower part of the drying chamber 1, and 3 is a cleaning item placing shelf 2. 1 shows a rotary air ejector including a plurality of air ejection nozzles 3a facing the mounted object to be cleaned.

Explaining this further with reference to the drawings, the drying chamber 1 is provided with a prefilter 4 and a hepa filter 5 on an upper portion thereof, that is, a ceiling surface, and at a lower portion of the drying chamber 1, a place where an object to be cleaned is placed is ventilated. The object-to-be-cleaned shelf 2 formed of a wire mesh having a property is provided. An opening / closing lid 6 for closing the entrance and exit of the object to be cleaned is provided on the side surface of the drying chamber 1. In addition, the opening / closing lid 6 was provided with a receiving piece 7 projecting from the side surface of the drying chamber 1 because the opening / closing lid 6 serves as a stand for an object to be cleaned when the opening / closing lid 6 is opened. Reference numeral 8 denotes an airtight chamber which is provided on the lower surface of the object-to-be-cleaned shelf 2 and communicates with the drying chamber 1 through the object-to-be-cleaned object shelf 2, and 9 makes the lower surface of the airtight chamber 8 face an intake port 9a. The exhaust fan 9 is driven to generate an air flow of about 13 m / s from the upper side to the lower side in the drying chamber 1 by driving the exhaust fan 9.

As the air flow, air from room temperature to about 80 degrees Celsius is appropriately used according to the object to be cleaned.

Reference numeral 10 denotes a sound deadening box connected to the discharge port 9 b of the exhaust fan 9. The sound deadening box 10 is mounted on an underframe 11 that supports the exhaust fan 9, and the sound deadening box 10 has an internal structure. And a passage meandering by the plate pieces 10a alternately projecting from the opposite side.

Reference numeral 12 denotes a storage container for storing the object to be cleaned, and the storage container 12 has a breathable metal net 12a only on the bottom surface and a blind plate 12b such as a metal plate around the net.

Thus, when the object to be cleaned is placed in the drying chamber 1 with the container 12 housed therein and the exhaust fan 7 is driven after the opening / closing lid 6 is closed, the object to be cleaned is above the drying chamber 1. Is dried by being exposed to a downward air flow. However, when the object to be cleaned has a complicated shape, a portion that is difficult to be exposed to the air flow is generated, and as a result, it takes time to dry. Therefore, the rotary air ejector 3 having a plurality of air ejection nozzles 3a is provided above the object to be cleaned so as to stir the air flow generated in the drying chamber 1 from the upper side to the lower side. To explain this, the rotary air ejector 3 is rotated by a motor 13. A T-shaped tube 14a is connected to a lower end of a vertical tube 14 to form a rotary air ejector main body, and air is supplied to both ends of the T-shaped tube 14a. The air jet nozzle 3a is attached so that the air jet nozzle 3a rotates about the vertical pipe 14. The air jet nozzle 3a is attached to the T-shaped pipe 14a by attaching air to both ends of the T-shaped pipe 14a. The ejection angle of the ejection nozzle 3a is rotatably mounted so that the ejection angle can be adjusted separately for the left and right, and the mounting angle is gradually adjusted from the state of directing downward as shown in FIG. I made it possible to save.

Thus, when the rotary air ejector 3 is rotated with different ejection angles of the air ejection nozzles 3a on the left and right sides, the drying is performed by the air flow from the air ejection nozzles 3a. The air flow generated in the chamber 1 from the upper side to the lower side was agitated so that the air flow efficiently acts on the object to be cleaned so that quick drying is performed. This drying device A is an automatic cleaning device as shown in FIG. 8 by automating the opening / closing of the opening / closing lid 6 thereof, the loading / unloading of the container 12 into / from the drying chamber 1, and the start / stop of the exhaust fan 9. It can also be used by incorporating it in B.

In the embodiment described above, the angle can only be changed from the state of directing downward to the state of inclining with respect to the vertical direction as shown by the chain double-dashed line. If the elbow pipe 14 is rotatably attached to both ends of the T-shaped pipe 14a and the base portion 3b of the air ejection nozzle 3a is rotatably attached to the lower end of the elbow pipe 15, the base portion 3b is rotated. By doing so, not only the position in the arrow direction can be changed, but also by rotating the elbow pipe 15, the angle can be changed from the state in which the air ejection nozzle 3a faces directly downward to the state in which it tilts with respect to the same as described above. .

[Effect of device]

 The drying device according to claim 1 having the above-described configuration has the following effects. It is possible to stir the air flow from the upper side to the lower side by the flow of the air ejected from the multiple air ejection nozzles of the rotary air ejector so that the air flow can be efficiently applied to all surfaces of the object to be cleaned. Therefore, the drying time can be shortened by that much, and by shortening the drying time, the occurrence of stains can be reduced and good drying can be performed. The structure is simple and the manufacturing is easy, because the rotary air ejector only needs to be exposed above the object to be cleaned.

According to the drying device of the second aspect, the following effects are further exhibited. Air ejection Since the mounting angle of the nozzle is adjustable, the air flow can be adjusted according to the shape of the object to be cleaned and the drying time can be shortened.
