A bidet comprises: one or more part groups including a plurality of element parts; a control device that diagnoses whether the plurality of element parts included in the one or more part groups operate normally according to a diagnosis mode including a regular diagnosis mode for diagnosing whether the one or more part groups are operating normally when in use by a user and a precise diagnosis mode for diagnosing whether the one or more part groups are operating normally when not in use by the user; a load input unit that applies a predetermined electric load for diagnosis to a part to be diagnosed, which is at least one of the plurality of element parts, in the precise diagnosis mode; and an output sensing unit that senses an electrical output value output from the part to be diagnosed when the electric load for diagnosis is applied.

A drying device includes an automatically adjustable shield film, a shielding region which can be automatically set according to the extent that a shield film part opens and closes an opening, a time loss of shield film replacement can be reduced, and drying defects due to improper installation of the shield film can be improved.

To provide a coating drier facility that has only a small heat loss and saves energy, a coating drier facility includes: a drier chamber configured to dry a coated object; a heater for heating air; an air supplier for supplying the air heated by the heater into the drier chamber; an air collector for collecting air from the drier chamber; and a treatment device for treating a volatile substance in the air that the air collector has collected, wherein the heater doubles as the treatment device.

Methods and apparatuses for drying web substrates are described. In one embodiment, a method of drying a web substrate may comprise supplying air to a first dryer head located proximate a web conveyer, the air within the first dryer head having a temperature of less than 176 degrees C., directing air from the first dryer head toward the web conveyer at a velocity greater than 1000 m/min and forming a first drying region, and advancing the web substrate in a first direction on the web conveyer and through the first drying region.

The present application relates to a drying device used for drying a part to be dried. The drying device comprises a drying oven having a first surface and a second surface. The first surface and the second surface are arranged opposite to and spaced apart from each other to form a drying channel allowing the part to be dried to pass through; the first surface is provided with a first air blow port; the first surface and/or the second surface is provided with an air exhaust port; and the second surface is further provided with an air suction port.

A dryer for portable electronic devices includes a hollow case having a top section and a bottom section that open and close in a clamshell-type fashion. The case further includes an interior compartment that is dimensioned to receive a vacuum pump, a nitrogen bottle, hoses, and most portable electronic devices. On one of the outer walls is a vacuum port for connecting a hose to the vacuum pump to remove moisture from the case interior. Adjacent the vacuum port is a nitrogen inlet port for connecting a second hose to the nitrogen bottle to deliver nitrogen to the case interior. Accordingly, the pump is activated for a predetermined duration to remove atmospheric water vapor and then the case is saturated with nitrogen to remove any residual moisture from the electronic device.

A drying apparatus according to the present invention and a laundry drying machine including the same circulate only some of humid air introduced from a drum and discharge the remaining humid air through a discharge port, and then introduce mixed air, in which external air introduced through an introduction port and circulated humid air are mixed, into the drying duct to supply the air to the drum. Accordingly, since air in which there is little moisture may be circulated, drying performance of the drying apparatus may be improved.

Further, by disposing an introduction fan or a discharge fan adjacent to the discharge port and mixing the humid air with the external air, since the air of which the moisture amount is little may be discharged to the outside of a cabinet, or the air discharged through the discharge port may be quickly discharged to the outside of the cabinet by the discharge fan, occurrence of dew condensation in the cabinet may be prevented.

A dryer apparatus is disclosed comprising a container having a container inlet and outlet, a pump that is configured to motivate a first air-vapor mixture flow via the container inlet and via the container outlet, a heating device configured to heat the first air-vapor mixture, a selector with at least two states, a compressor that is configured to compress and motivate a part of the first air-vapor mixture flow as a second air-vapor mixture flow, to flow through a first heat exchanger and to flow through a second heat exchanger and a pressure reducing device that is configured to reduce the pressure of said second air-vapor mixture downstream said first heat exchanger. The selector is configured to direct most of the first air-vapor mixture to flow in a closed cycle through the container, or configured to exchange most of the first air-vapor mixture with air located outside the apparatus.
