  By the way, in the method of blowing compressed air onto a workpiece, particularly when the surface area of the workpiece is increased, a high amount of energy is required, resulting in a problem that the running cost is increased. For this reason, a method of forming and circulating an air flow using a fan or the like is conceivable. However, compared with a method of blowing compressed air on a workpiece, another method of reducing residual liquid and foreign matter attached to the workpiece is reduced. There are challenges.

  In addition, the conventional blowing device includes a demister for capturing mist in the air, but there is a problem in the effect of capturing mist contained in air that is a high-speed fluid. That is, when the effect of trapping mist is low, there is a problem that mist remains in the air that has passed through the demister, and this mist adheres to the workpiece.

  The above-mentioned problem also applies to a cleaning blow device that removes water droplets remaining on the workpiece after the workpiece is cleaned.

  In view of the above circumstances, an object of the present invention is to provide a blow device and a cleaning blow device capable of suppressing the increase in size and cost of the device and enhancing the work blowing effect.

  Another object of the present invention is to provide a blow device and a cleaning blow device that can suppress the increase in size and cost of the device and increase the supplemental effect of mist in consideration of the above circumstances.

  Another object of the present invention is to provide an automotive part that has been processed by the blow device or the cleaning blow device.

  1st invention is a blower which removes the water | moisture content adhering to the workpiece | work with the air in airflow, Comprising: In order to hold | grip the said workpiece | work arrange | positioned at the said 1st process part which has a predetermined | prescribed volume, and the said 1st process part A workpiece gripping portion, a second processing portion having a predetermined volume, an airflow generation source arranged in the second processing portion to generate an airflow, and a flow velocity of air in the airflow generated by the airflow generation source. And a flow velocity increasing portion that increases at a position before hitting.

  In this case, the flow velocity increasing portion is configured by a flow path wall of a connection flow path that is located at a site where the air in the air flow generated by the air flow generation source reaches the workpiece, and the flow path wall is the air flow It is preferable that the inclined wall is inclined downward from the generation source toward the workpiece.

  In this case, the first processing unit has a carry-in port that allows the workpiece to be taken in and out, and an open / close door that opens and closes the carry-in port, and the inclined wall opens the carry-in port by the open / close door. It is preferable that the retracting portion of the opening and closing door is configured.

  In this case, a third processing unit having a predetermined volume, a mist removing unit disposed in the third processing unit for removing mist in the air, and a flow rate for reducing the flow rate of air entering the mist removing unit A lowering portion.

  In this case, it is preferable that the flow velocity reduction unit is a housing of the third processing unit in which the mist removing unit is disposed and a volume is formed larger than that of the housing of the first processing unit.

  In this case, it is preferable that the mist removing unit is provided so as to be inclined with respect to the opening surface of the housing of the third processing unit.

  2nd invention is the components for motor vehicles by which the blow process was performed by the said blow apparatus.

  According to the blow device of the present invention, the flow velocity of air in the airflow generated by the airflow generation source is increased by the flow velocity increasing means. For this reason, air becomes a high-speed fluid. Thereby, the airflow formed with the air of the high-speed fluid wraps the work and peels off the water adhering to the work. For this reason, the water | moisture content adhering to a workpiece | work becomes scattered easily and a water | moisture content is removed from a workpiece | work. As a result, the work blowing effect is enhanced without using compressed air.

  The flow velocity increasing part is composed of the flow path wall of the connection flow path located at the part where the air in the air flow generated at the air flow generation source reaches the work, and the flow path wall is inclined downward from the air flow generation source toward the work By being an inclined wall, the opening area of the connection channel is reduced by the inclined wall. Thereby, the flow velocity of air easily increases at the position immediately before the collision with the workpiece using the existing components.

  The first processing unit has a carry-in port that enables loading and unloading of a workpiece, and an open / close door that opens and closes the carry-in port, and the inclined wall serves as a retracting unit for the open / close door when the open / close door opens the carry-in port. In addition, the inclined wall is an indispensable component from the beginning, and the air flow rate can be increased by using the indispensable component. Thereby, the flow velocity of air can be increased without enlarging the apparatus.

  By having the flow velocity lowering portion that reduces the flow velocity of the air entering the mist removing portion, the flow velocity of the air entering the mist removing portion is reduced. Thereby, the flow velocity of the air passing through the mist removing unit is reduced, and the mist capturing effect by the mist removing unit is increased. As a result, it is possible to suppress an increase in cost required for manufacturing and operating the apparatus and enhance the mist recovery effect.

  The flow rate lowering part is a casing of the third processing unit in which the mist removing unit is arranged and the volume is formed larger than that of the casing of the first processing unit. It can be reduced, and an increase in cost required for manufacturing and operating the apparatus can be suppressed.

  Since the mist removing unit is provided so as to be inclined with respect to the opening surface of the housing of the third processing unit, the contact area of the air with respect to the mist removing unit is increased. Thereby, the collection | recovery effect of the mist by a mist removal part can be heightened.

  A blow device, a cleaning blow device, and automotive parts according to a first embodiment of the present invention will be described with reference to the drawings.

[Blow device]
The blow device will be described.

  As shown in FIGS. 1 to 4, the blow device 10 includes a blow chamber 12, an air flow generation chamber 14, a connection flow channel 16, a drain discharge chamber 18, a mist removal chamber 20, and the like. It is formed to be able to communicate.

(Blow room)
The blow chamber 12 will be described.

  The blow chamber 12 has a blow chamber casing 22 having a predetermined volume. For example, a work gripping portion 24 that grips a work W (see FIG. 2) and an airflow generation mechanism 26 for generating an airflow are accommodated in the blow chamber casing 22. In the blow chamber 12, moisture or the like adhering to the work W is pulled by the air in the airflow environment, and peeled off from the work W and removed. In the airflow environment, air flies at a predetermined flow velocity.

  Note that “air” in the present embodiment does not mean compressed air. That is, it means air that is generated by a fan or the like and flies in the airflow.

  The workpiece gripping part 24 is a jig for fixing the workpiece W, for example. The jig has a predetermined gripping mechanism, and can fix the workpiece W or release the workpiece W. The jig is configured to be rotatable about a predetermined rotation axis (not shown), and the workpiece W can be rotated about the rotation axis while the workpiece W is gripped.

  The airflow generation mechanism 26 is, for example, a rotary type or a fixed type, and generates an airflow inside the blow chamber casing 22. The air in the airflow is directed to the workpiece W at a predetermined flow rate.

  In a part of the blow chamber casing 22 of the blow chamber 12, a carry-in port 28 for allowing the workpiece W to be taken in and out is formed. The blow chamber 12 includes an opening / closing door 30 that opens and closes the carry-in entrance 28.

  The workpiece W corresponds to a machined part as an example.

  The blow chamber 12 is an embodiment of the “first processing unit” in the present invention.

(Airflow generation room)
The airflow generation chamber 14 will be described.

  The air flow generation chamber 14 is formed at an upstream position in the air flow direction with respect to the blow chamber 12. The air flow generation chamber 14 has an air flow generation chamber casing 52 having a predetermined volume. For example, an air flow generation source 32 for generating an air flow is accommodated in the air flow generation chamber casing 52 of the air flow generation chamber 14. When the airflow generation source 32 is driven, an airflow is generated inside the blowing device 10.

  As the air flow generation source 32, for example, a fan or the like that rotates around an axis by a drive source (not shown) such as a motor is employed. As described above, in the present embodiment, airflow generating means such as a fan is merely provided instead of a compressed air supply source such as a compressor and a nozzle.

  The air flow generation chamber 14 is an embodiment of the “second processing unit” in the present invention.

(Connection flow path)
The connection channel 16 will be described.

  The connection flow path 16 connects the air flow generation chamber 14 and the blow chamber 12 and functions as an air flow path for air to flow. The connection flow path 16 is located upstream of the blow chamber 12 in the air flow direction. The connection channel 16 has a connection channel housing 54 having a predetermined volume.

  Note that the connection flow path casing 54 of the connection flow path 16 may be constituted by, for example, one independent casing, or may be integrated as a part of the blow chamber casing 22 of the blow chamber 12. The airflow generation chamber 14 may be configured integrally as a part of the airflow generation chamber housing 52.

  In the present embodiment, as an example, a configuration in which the connection flow path casing 54 of the connection flow path 16 is configured integrally with the blow chamber casing 22 of the blow chamber 12 is employed.

  Here, the connection flow path 16 is provided with a flow velocity increasing portion 34 that increases the flow velocity of the air generated by the air flow generation source 32. The flow rate increasing portion 34 is a flow path wall of the connection flow path 16. Specifically, the flow velocity increasing part 34 is configured by an inclined wall 36 for positioning the work gripping part 24 that grips the work W in the airflow space generated by the airflow generation source 32. The inclined wall 36 is, for example, the upper wall of the connection flow path 16 and is inclined downward from the airflow generation chamber 14 toward the blow chamber 12.

  Moreover, the inclined wall 36 may be comprised by the right-and-left both sides wall of the connection flow path 16, for example.

  The inclined wall 36 is an aspect of the flow path wall and an embodiment of the flow velocity increasing unit 34.

  For this reason, when the air hits the inclined wall 36, the air travels along the downward inclination direction of the inclined wall 36 and wraps around the workpiece W. In addition, the opening area of the opening part located in the blow chamber 12 side becomes smaller than the opening area of the opening part located in the airflow generation chamber 14 side. As a result, as indicated by Bernoulli's theorem, the flow velocity of air on the blow chamber 12 side becomes faster than the flow velocity of air on the air flow generation chamber 14 side. The air whose flow velocity is increased becomes an air current and wraps the workpiece W. As a result, moisture or the like adhering to the workpiece W is pulled by the air in the airflow and peels off from the workpiece W, and is scattered vigorously, increasing the blowing effect.

  Thus, the air flow velocity can be increased only by forming the inclined wall 36 as the flow velocity increasing portion 34 in the connection channel 16. Thus, the blowing effect can be enhanced without using a compressed air supply source, without increasing the size of the airflow generation source 32, and without increasing the driving force of the airflow generation source 32. The blow effect can be improved while suppressing the increase in size and cost of the apparatus.

  In addition, on the upper surface of the inclined wall 36, a retracting portion 38 is formed in which the open / close door 30 is retracted when the open / close door 30 opens the carry-in port 28 of the blow chamber 12. As a result, the inclined wall 36 has two functions: a function as the flow velocity increasing portion 34 that increases the flow velocity of air and a function as the retracting portion 38 of the open / close door 30. As a result, an increase in size and cost of the blow device 10 can be prevented.

  Here, although the inclined wall 36 was raised as an example of the flow velocity increasing part 34, it is not restricted to this. For example, an obstacle (not shown) that collides with air or airflow is provided in a portion of the connection channel 16 that is close to the workpiece W, and the opening area of the connection channel 16 is reduced in the vicinity of the obstacle. Also good. If the opening area of the connection flow path 16 becomes small, the flow velocity of the air passing therethrough increases, and the blow effect can be enhanced.

  In addition, the configuration is not limited to the configuration in which the upper wall of the connection channel 16 is formed as the inclined wall 36. For example, a convex recess (not shown) is formed inside the upper wall of the connection channel 16 and the like. The opening area may be reduced in the part.

  Furthermore, in this embodiment, although the structure which provided the flow velocity increase part 34 or the inclined wall 36 in the connection flow path 16 was illustrated, it is not restricted to these. For example, the flow velocity increasing portion 34 or the inclined wall 36 may be provided separately or integrally with at least a part of the blow chamber 12, and separately or integrally provided with at least a part of the air flow generation chamber 14. It may be done.

  Moreover, the following deformation | transformation can also be considered as the flow velocity increase part 34. FIG. For example, the volume size of the blow chamber housing 22 of the blow chamber 12 is determined based on the volume of the connection flow channel housing 54 of the connection flow channel 16 or the volume of the air flow generation chamber housing 52 of the air flow generation chamber 14. May be set to be smaller. As a result, the flow velocity of the air that has entered the blow chamber 12 can be increased.

  For the part where the airflow is difficult to enter or the concave part where the airflow is difficult to enter on the side surface of the workpiece W, the compressed air supply means is used partially or limitedly, and the compressed air is applied to the part or the concave part. You may spray. Thereby, a movement is given to the said part or the said recessed part, and it becomes possible to scatter foreign substances, such as a water | moisture content, from the workpiece | work W with the air of airflow environment.

(Drain discharge chamber)
The drain discharge chamber 18 will be described.

  The drain discharge chamber 18 has a function of collecting water such as a cleaning liquid scattered from the work W mainly in the blow chamber 12 and draining it to the outside.

  The drain discharge chamber 18 is formed at a downstream position along the air flow direction with respect to the blow chamber 12. The drain discharge chamber 18 has a drain discharge chamber casing 56 having a predetermined volume.

  In this embodiment, for example, the drain discharge chamber casing 56 of the drain discharge chamber 18 is configured integrally with the blow chamber casing 22 of the blow chamber 12, but may be configured separately. Good.

(Mist removal room)
The mist removal chamber 20 will be described. In this specification, “mist” is defined as including not only moisture but also moisture containing foreign matters such as oil.

  The mist removal chamber 20 is formed at a downstream position in the air flow direction with respect to the blow chamber 12 or the drain discharge chamber 18. The mist removal chamber 20 has a mist removal chamber housing 46 having a predetermined volume.

  The mist removal chamber 20 is provided between the drain discharge chamber 18 and the airflow generation chamber 14 along the direction in which the air flows, and the air that has passed through the blow chamber 12 passes through the drain discharge chamber 18 and flows into the mist removal chamber 20. The mist removal chamber casing 46 is entered. Then, the air that has passed through the mist removal chamber 20 enters the airflow generation chamber casing 52 of the airflow generation chamber 14. Thereafter, the air enters the blow chamber housing 22 of the blow chamber 12 through the connection flow path 16 and circulates inside the blow device 10.

  The mist removal chamber housing 46 of the mist removal chamber 20 houses a mist removal device 40 that separates and removes liquid particulates (defined as mist) contained in the flowing air from the air. By providing the mist removing device 40, the mist in the airflow is removed, so that it is possible to prevent the mist from adhering to the workpiece W gripped by the workpiece gripping portion 24 and being contaminated.

  The mist removing device 40 is an embodiment of the “mist removing unit” of the present invention.

  The mist removing chamber 20 is provided with a flow velocity reduction unit 42 that reduces the flow velocity of the air entering the mist removing device 40. The flow velocity lowering portion 42 corresponds to, for example, the mist removal chamber housing 46 of the mist removal chamber 20 that has a larger volume than the blow chamber 12 or the drain discharge chamber 18.

  In the aspect in which the drain discharge chamber casing 56 of the drain discharge chamber 18 is configured integrally with the blow chamber casing 22 of the blow chamber 12, the volume of the mist removal chamber casing 46 of the mist removal chamber 20. Is set to be larger than the entire volume of each casing of the blow chamber 12 and the drain discharge chamber 18.

  For this reason, the opening area in the predetermined part of the mist removal chamber 20 is larger than the opening area in the predetermined part of the drain discharge chamber 18, and the mist removal chamber of the mist removal chamber 20 from the drain discharge chamber casing 56 of the drain discharge chamber 18. The flow velocity of the air that has entered the interior of the housing 46 decreases. Then, the air whose flow velocity is reduced enters the mist removing device 40. For this reason, the time required for the air to pass through the mist removing device 40 becomes longer. As a result, the mist capturing effect in the mist removing device 40 is enhanced, and the air after passing through the mist removing device 40 contains almost no mist.

  Here, some water droplets adhere to the exit side of the capturing surface 40A of the mist removing device 40. By passing the air whose flow velocity is lowered through the trapping surface 40A of the mist removing device 40, it is possible to suppress water droplets on the outlet side from being pulled and circulated again, and adhering to the workpiece W.

  In the present embodiment, the “volume of the mist removal chamber” means an area occupied by the space inside the mist removal chamber housing 46. Similarly, the “volume of the blow chamber casing 22 or the drain discharge chamber casing 56” means an area occupied by the space of the blow chamber casing 22 or the drain discharge chamber casing 56.

  Further, even if the size of the mist removal chamber casing 46 of the mist removal chamber 20 and the drain discharge chamber side casing 56 of the drain discharge chamber 18 are substantially the same, the inside of the drain discharge chamber side casing 56 of the drain discharge chamber 18. By providing an interfering object (not shown) in the opening, it is possible to intentionally reduce the opening at a predetermined portion of the drain discharge chamber side housing 56 of the drain discharge chamber 18. Even in this configuration, the flow rate of the air that has entered the mist removal chamber housing 46 of the mist removal chamber 20 from the drain discharge chamber housing 56 of the drain discharge chamber 18 is reduced.

  The mist removing device 40 is installed so as to block the air flow path inside the mist removing chamber so that air passes through. The capturing surface 40A for capturing the mist of the mist removing device 40 is provided so as to be inclined with respect to the opening surface 44A in the inlet portion 44 of the mist removing chamber 20. In other words, the capturing surface 40A of the mist removing device 40 is not parallel to the opening surface 44A of the inlet portion 44 of the mist removing chamber housing 46 of the mist removing chamber 20, but is inclined by a predetermined inclination angle. .

  For this reason, the contact area (or contact area) with respect to the capture surface 40A of the air mist removing device 40 increases. Thereby, the trap effect of the mist in the mist removal apparatus 40 becomes high, and mist is hardly contained in the air after passing the mist removal apparatus 40. As a result, it is possible to prevent the mist in the air from adhering to the workpiece W and being contaminated. In particular, due to the synergistic effect with the flow velocity reduction unit 42 provided in the mist removing chamber 20, the mist capturing effect in the mist removing device 40 is remarkably enhanced.

  The opening surface 44A of the inlet portion 44 of the mist removing chamber housing 46 of the mist removing chamber 20 is defined when the inlet portion 44 determined by the design of the mist removing device 40 is cut in a cross-sectional direction perpendicular to the air flow. It means the opening surface.

  The mist removal chamber housing 46 of the mist removal chamber 20 has an inclined bottom portion 48 that is inclined downward toward the blow chamber 12 side or the drain discharge chamber 18 side. In other words, with reference to the blow chamber 12 side or the drain discharge chamber 18 side, the inclined bottom 48 is inclined upward in the direction away from the blow chamber 12 side or the drain discharge chamber 18 side. For this reason, moisture or mist containing the cleaning liquid or the like on the blow chamber 12 side or the drain discharge chamber 18 side is less likely to enter the mist removal chamber 20 due to the influence of gravity. Thereby, it can suppress that the mist removal chamber 20 and the mist removal apparatus 40 are contaminated. Further, the mist captured by the mist removing device 40 of the mist removing chamber 20 can be guided to the drain discharge chamber 18 using the inclined bottom wall 48, and the mist discharging effect can be enhanced.

  On the inner wall of the mist removal chamber 20, a cleaning unit 50 for removing dirt attached to the inner wall of the mist removal chamber 20 may be provided as appropriate. The cleaning unit 50 includes, for example, a cleaning nozzle, and the cleaning liquid is ejected from the cleaning nozzle at a predetermined timing. Thereby, the inner wall of the mist removal chamber 20 is washed, and the mist removal chamber 20 is maintained in a clean state. As a result, it is possible to prevent the mist from adhering again to the air flowing through the mist cleaning chamber 20, and consequently, the air containing the mist can be prevented from coming into contact with the workpiece W and being contaminated. In addition, the cleaning liquid sprayed from the cleaning unit 50 includes mist and falls to the drain discharge chamber 18 side through the inclined bottom wall 48.

  The mist removal chamber 20 is an embodiment of the “third processing unit” in the present invention.

  Next, the operation of the blow device 10 of this embodiment will be described.

  By providing the blow device 10 with the flow velocity increasing portion 34, the flow velocity of the air generated by the air flow generation source 32 is increased at a position immediately before the collision of the workpiece W. For this reason, the air becomes a high-speed fluid, and the tensile force of the air of the airflow that wraps around the workpiece W becomes strong. As a result, the moisture adhering to the workpiece W is peeled off and scattered vigorously, and the moisture is efficiently removed from the workpiece W. As a result, the blowing effect can be enhanced without using a compressed air supply source and without increasing the size of the air flow generation source 32.

  In particular, the flow velocity increasing portion 34 is configured by a flow path wall of the connection flow path 16 located at a portion where the air in the air flow generated by the air flow generation source 32 reaches the workpiece W, and the flow path wall extends from the air flow generation source 32. Since the inclined wall 36 is inclined downward toward the workpiece W, the opening area of the connection channel 16 is reduced by the inclined wall 36. Thereby, the flow velocity of air can be easily increased at the position immediately before the collision of the workpiece W using the existing components.

  In addition, the inclined wall 36 is originally an indispensable component by serving also as the retracting portion 38 of the open / close door 30 when the open / close door 30 opens the carry-in entrance 28, and the essential component is It can be used to increase the air flow rate. Thereby, the increase in the number of parts can be suppressed, and the air flow rate can be increased without increasing the size of the blow device 10.

  Furthermore, by having the flow velocity lowering portion 42 for reducing the flow velocity of the air entering the mist removing device 40, the air flow velocity is lowered at a position immediately before entering the mist removing device 40. Thereby, the flow velocity of the air passing through the mist removing device 40 is reduced, and the mist capturing effect by the mist removing device 40 is enhanced. As a result, the effect of collecting mist can be enhanced.

  In particular, the flow velocity reduction portion 42 is a mist removal chamber housing 46 of the mist removal chamber 20 formed with a larger volume (or opening area) than each housing of the blow chamber 12 or the drain discharge chamber 18, When the air enters the mist removal chamber housing 46, the air flow velocity decreases. Thereby, the flow velocity of air can be reduced using the existing components, the increase in the number of parts can be prevented, and the increase in the size and operating cost of the blower 10 can be suppressed.

  In addition, since the mist removing device 40 is provided so as to be inclined with respect to the opening surface 44 </ b> A of the mist removing chamber 20, the contact area of air with the mist removing device 40 is increased. Thereby, the recovery effect of the mist by the mist removing apparatus 40 can be enhanced.

  In addition, the flow velocity increasing unit 34 and the flow velocity decreasing unit 42 of the blow device 10 can be applied to a cleaning blow device.

[Cleaning blow equipment]
Next, the cleaning blow device will be described. In addition, about the structure which has the function similar to the structure of the blow apparatus 10, the same code | symbol and the same name are attached | subjected, and the description is abbreviate | omitted suitably.

  As shown in FIG. 5, the cleaning blow device 60 is formed such that a plurality of rooms and flow paths such as a blow chamber 12, an air flow generation chamber 14, a connection flow channel 16, a drain discharge chamber 18, and a mist removal chamber 20 can communicate with each other. ing. The blow chamber 12 of the cleaning blow device 60 has not only a blow function but also a cleaning function that can clean the workpiece W.

  The cleaning blow device 60 is provided with a flow velocity increasing portion 34. The flow velocity increasing part 34 is configured by, for example, an inclined part 36 that forms a flow path wall of the connection flow path 16. Thereby, the moisture which the air adhered to the workpiece | work W peels, and the scattering effect of a water | moisture content becomes high.

  The blow chamber 12 has a carry-in entrance 28 that allows the workpiece W to be taken in and out, and an open / close door 30 that opens and closes the carry-in entrance, and the inclined wall 36 opens and closes when the open / close door 30 opens the carry-in entrance 28. The retracting portion 38 of the door 30 is formed.

  In addition, although the thing similar to the form of the flow velocity increase part 34 of the blowing apparatus 10 is applicable also about the other form of the flow velocity increase part 34, since it overlaps, those description is abbreviate | omitted.

  Also in the cleaning blow device 60, similarly to the blow device 10, the air flow velocity can be easily increased at a position immediately before the collision with the workpiece W. Thereby, the workpiece | work W can be wrapped with the air of high-speed fluid, and the scattering effect of the water | moisture content adhering to the workpiece | work W can be heightened.

  Further, the flow velocity increasing portion 34 is constituted by a flow path wall of the connection flow path 16 located at a site where the air generated by the air flow generation source 32 reaches the work W, and the flow path wall is changed from the air flow generation source 32 to the work W. Since the inclined wall 36 is inclined downward, the opening area of the opening of the connection channel 16 is reduced by the inclined wall 36. Thereby, the flow velocity of air can be easily increased at the position immediately before the collision of the workpiece W using the existing components.

  Further, the inclined wall 36 of the connection channel 16 is an indispensable component from the beginning because the inclined wall 36 also serves as a retracting portion 38 of the opening / closing door when the opening / closing door 30 opens the carry-in entrance 28. These components can be used to increase the air flow rate. Thereby, the flow velocity of air can be increased without enlarging the apparatus.

  In addition, the cleaning blow device 60 is provided with a flow velocity reduction unit 42. The flow velocity reduction unit 42 is configured by, for example, a mist removal chamber housing 46 of the mist removal chamber 20. The volume of the mist removal chamber housing 46 in the mist removal chamber 20 is set to be larger than the volume of each housing of the blow chamber 12 and / or the drain discharge chamber 18.

  Thereby, when the air enters the mist removal chamber 20 from the drain discharge chamber 18, the flow velocity of the air decreases. And since the time required for air to enter the mist removing device 40 and the air to pass through the mist removing device 40 in a state where the flow velocity of the air is lowered, the mist is efficiently captured.

  The capturing surface 40A for capturing the mist of the mist removing device 40 is provided so as to be inclined with respect to the opening surface 44A in the inlet portion 44 of the mist removing chamber 20. In other words, the capturing surface 40A of the mist removing device 40 is not parallel to the opening surface 44A at the inlet 44 of the mist removing chamber 20, but is inclined by a predetermined inclination angle.

  For this reason, the contact area (or contact area) with respect to the mist removal apparatus 40 of air becomes large. Thereby, the trap effect of the mist in the mist removal apparatus 40 becomes high, and mist is hardly contained in the air after passing the mist removal apparatus 40. As a result, it is possible to prevent the mist in the air from adhering to the workpiece W and being contaminated. In particular, due to the synergistic effect with the flow velocity reduction unit 42 provided in the mist removing chamber 20, the mist capturing effect in the mist removing device 40 is remarkably enhanced.

[Auto parts]
Next, automotive parts will be described.

  As shown in FIG. 6, the workpiece W subjected to the blow process or the cleaning blow process by the blow apparatus 10 or the cleaning blow apparatus 60 is, for example, an automotive part 70, specifically, an automotive cylinder head or cylinder. This applies to machined products such as blocks and transmissions.

  In the present specification, the “cleaning blow process” means that the blow process is performed on the workpiece W after the cleaning process.

  The automotive part 70 that has been blown or washed by the blower 10 or the washing blower 60 has a high level of blowing effect or washing blow effect. For this reason, no foreign matter remains on the automobile component 70 and is not contaminated, and the surface is finished in a clean state.

  Each embodiment described above is only an example for explaining the present invention, and various modifications can be made without departing from the gist of the present invention.
