A recording apparatus includes a supply portion for supplying an airflow, a blowing port that is formed in a slit-like form following a width direction orthogonal to a conveying direction of a discharged medium, for blowing out the airflow supplied from the supply portion, the blowing port being formed with a channel, through which the airflow flows, extending in a direction substantially perpendicular to a conveyance region of the discharged medium, from an inlet side at which the airflow is introduced, to an outlet side, and a supporting member provided on the inlet side of the blowing port to support opposing wall faces of the blowing port, while allowing passage of the airflow. The blowing port has a narrow portion that partially narrows a width of the channel, father on the outlet side than the supporting member of the wall faces forming the channel.

Recording apparatus

A recording device includes a recording head, a conveyance portion that conveys a liquid-ejected medium so that the liquid-ejected medium passes through a position facing the recording head, a supply portion for air, and an air blowing mechanism that is disposed on an upstream side of the recording head in a relative moving direction between the recording head and the liquid-ejected medium, the air blowing mechanism including an air blow-out port for blowing out air from the supply portion toward a gap between the recording head and the liquid-ejected medium. The air blow-out port includes a plurality of slits that are lined up in a direction intersecting the relative moving direction, and the plurality of slits are lined up in the direction intersecting the relative moving direction so that long sides of the adjacent slits have regions facing each other in a direction orthogonal to the long sides.

Recording device

An ultrafine bubble generating apparatus and an ultrafine bubble generating method capable of efficiently generating an ultrafine bubble-containing liquid with high purity are provided. In order to this, a heating element provided in a liquid is caused to generate heat, and film boiling is made on an interface between the liquid and the heating element. A film boiling bubble is generated by the film boiling, and ultrafine bubbles are thus generated near the film boiling bubble.

Ultrafine bubble generating method, ultrafine bubble generating apparatus, and ultrafine bubble-containing liquid

A discharge apparatus includes a discharge unit configured to discharge a liquid to a medium, a suction unit, and a supply unit configured to supply a gas to the suction unit. The suction unit includes an opening facing the medium, and a suction groove including an arc-shaped inner wall surface inside the opening and configured to suck mist around the medium. An outlet portion configured to blow out the gas supplied from the supply unit toward the inner wall surface is provided in the opening.

Discharge apparatus and suction unit

Provided is an ultrafine bubble generating apparatus that generates ultrafine bubbles by generating film boiling by causing a heater provided in a liquid to generate heat, the ultrafine bubble generating apparatus including: an element substrate including a first heater that generates the film boiling in the liquid and a second heater that is arranged adjacent to the first heater, in which the first heater and the second heater are driven in different timings.

Ultrafine bubble generating apparatus and ultrafine bubble generating method

Provided is an UFB generating apparatus and an UFB generating method capable of efficiently generating an UFB-containing liquid with high purity. The ultrafine bubble generating apparatus includes a generating unit that generates ultrafine bubbles in a liquid and a post-processing unit that performs predetermined post-processing on the ultrafine bubble-containing liquid generated by the generating unit. The generating unit generates the ultrafine bubbles by causing a heating element, which is provided in the liquid on which the pre-processing is performed, to generate heat to generate film boiling on an interface between the liquid and the heating element.

The present invention provides a fine bubble generating apparatus capable of generating fine bubbles efficiently. The present invention includes a fluid flow passage that includes a narrow portion in at least a part thereof, a heating part capable of heating a liquid flowing through the fluid flow passage, and a controlling unit that controls the heating part. The controlling unit controls the heating part to generate film boiling in the liquid to generate ultrafine bubbles.

Fine bubble generating apparatus, fine bubble generating method, and fine bubble-containing liquid

Provided is an UFB generating apparatus and an UFB generating method capable of efficiently generating an UFB-containing liquid with high purity. To this end, the ultrafine bubble generating apparatus includes a pre-processing unit that performs predetermined pre-processing on a liquid W and a generating unit that generates ultrafine bubbles in the liquid on which the pre-processing is performed. The generating unit generates the ultrafine bubbles by causing a heating element, which is provided in the liquid on which the pre-processing is performed, to generate heat to generate film boiling on an interface between the liquid and the heating element.

A platen includes: a supporting portion that can support a sheet; a suction unit that sucks the sheet in such a manner as to attach the sheet to the supporting portion; a first ink receiver that receives ink ejected downstream of the leading end of the sheet passing the supporting portion; and a second ink receiver that receives ink ejected upstream of the trailing end of the sheet passing the supporting portion.

Printing apparatus and platen

A collection unit configured to collect ink mist generated due to a discharge of ink from a head configured to discharge the ink includes a filter for capturing the ink mist and a liquid supply portion configured to supply a liquid to the filter.

Inkjet apparatus and collection apparatus

A blowout port for gas is efficiently configured without impairing mist collection performance. Two blowout ports for gas are adjacent to each other by interposing a partition. An end of the partition is provided at a position near a deep side of the two blowout ports relative to ends of the two blowout ports so as to form a step.

Mist collection apparatus and liquid ejection apparatus

A printing apparatus according to the present invention includes a plurality of ejection heads for ejecting liquid and a plurality of mist collection units configured to collect mist generated by the ejection heads that are disposed along a medium conveyance direction. The plurality of mist collection units include a first mist collection unit. The first mist collection unit is provided to be inclined to the upstream side of a medium conveyance direction with regard to a perpendicular line perpendicular to a floor. The first mist collection unit has a liquid retention part disposed at the upstream side than an ink mist suction hole.

Printing apparatus

Gas is ejected toward a region between a liquid ejection head and a recording medium so as to enlarge and stabilize a vortex generated by an airflow generated by liquid droplets ejected from ejection ports. Accordingly, an airflow turbulence generated between the liquid ejection head and the recording medium is reduced and displacements of positions at which the liquid droplets are applied due to the airflow turbulence are reduced.

Recording apparatus, recording method, and liquid ejection head for recording an image by ejecting liquid droplets toward a recording medium while moving the liquid ejection head and the recording medium relative to each other

A platen disposed at a position at which the platen faces a printing head includes a contact portion that comes into contact with a recording medium, a non-contact portion that does not come into contact with the recording medium, and an ink receiving portion that receives ink ejected to beyond the recording medium. A recessed portion is formed between the ink receiving portion and the contact portion in the width direction of the recording medium so as to be lower than the contact portion in the vertical direction. A supply portion that supplies air to the recessed portion is formed upstream of the recessed portion in the conveyance direction of the recording medium.
