Abstract

A steam type clothing flattening device includes an electrical heating tray unit and a soleplate unit. The electrical heating tray unit is heated electrically to vaporize water in an upper vaporization chamber thereof, and has a discharge port for discharge of vapor from the upper vaporization chamber. The soleplate unit is coupled to an underside of and heated by the electrical heating tray unit. The soleplate unit cooperates with the electrical heating tray unit to define a lower vaporization chamber in communication with the discharge port, and has a plurality of vapor outlets extending through a bottom surface thereof for outletting vapor from the lower vaporization chamber.

First claim

What is claimed is:

1. A steam type clothing flattening device comprising:
an electrical heating tray unit heated electrically to vaporize water in an upper vaporization chamber thereof, and having a discharge port for discharge of vapor from said upper vaporization chamber; and
a soleplate unit coupled to an underside of and heated by said electrical heating tray unit, said soleplate unit cooperating with said electrical heating tray unit to define a lower vaporization chamber which is in communication with said discharge port, and having a plurality of vapor outlets that extend through a bottom surface thereof for outletting vapor from said lower vaporization chamber;
wherein said soleplate unit includes a soleplate mounted beneath said electrical heating tray unit in a stack, and a lower lid disposed between said soleplate and said electrical heating tray unit in a stack;
wherein said soleplate and said electrical heating tray unit cooperatively define said lower vaporization chamber;
wherein said lower lid has a connecting hole extending through top and bottom surfaces of said lower lid, and divides said lower vaporization chamber into an auxiliary vaporization region communicated with said discharge port of said electrical heating tray unit and said connecting hole, and a vapor release region connected between said connecting hole and said vapor outlets; and
wherein said lower lid further has a plate-shaped lid body stacked on top of said soleplate and being formed with said connecting hole, and a flow guide rib extending in a serpentine manner, and protruding upwardly from a top side of said plate-shaped lid body to abut against said electrical heating tray unit for surroundingly defining said auxiliary vaporization region of said lower vaporization chamber.

2. The steam type clothing flattening device as claimed in claim 1 , wherein said auxiliary vaporization region of said lower vaporization chamber is serpentine and has two ends respectively connected to said discharge port of said electrical heating tray unit and said connecting hole of said lower lid.

3. The steam type clothing flattening device as claimed in claim 2 , wherein:
said electrical heating tray unit includes
a heating tray disposed above said lower lid and said soleplate in a stack,
an upper lid covering a top side of said heating tray and cooperatively defining said upper vaporization chamber with said electrical heating tray, and
an electrical heating tube disposed in said heating tray and able to generate heat from electricity flowing therethrough; and

said heating tray has a bottom rib extending in a serpentine manner, and protruding from a bottom of said heating tray to mate with said flow guide rib of said lower lid for cooperatively surrounding said auxiliary vaporization region of said lower vaporization chamber.

4. The steam type clothing flattening device as claimed in claim 3 , wherein:
said upper lid is formed with a water inlet extending therethrough for introduction of water into said upper vaporization chamber; and
said upper vaporization chamber has a heating region extending along a longitudinal direction of said heating tray and having an end connected to said water inlet, and a main vaporization region extending and connected between another end of said heating region and said discharge port.

5. A steam type clothing flattening device comprising:
an electrical heating tray unit heated electrically to vaporize water in an upper vaporization chamber thereof, and having a discharge port for discharge of vapor from said upper vaporization chamber; and
a soleplate unit coupled to an underside of and heated by said electrical heating tray unit, said soleplate unit cooperating with said electrical heating tray unit to define a lower vaporization chamber which is in communication with said discharge port, and having a plurality of vapor outlets that extend through a bottom surface thereof for outletting vapor from said lower vaporization chamber;
wherein said soleplate unit includes a soleplate mounted beneath said electrical heating tray unit in a stack, and a lower lid disposed between said soleplate and said electrical heating tray unit in a stack;
wherein said soleplate and said electrical heating tray unit cooperatively define said lower vaporization chamber;
wherein said lower lid has a connecting hole extending through top and bottom surfaces of said lower lid, and divides said lower vaporization chamber into an auxiliary vaporization region communicated with said discharge port of said electrical heating tray unit and said connecting hole, and a vapor release region connected between said connecting hole and said vapor outlets;
wherein said electrical heating tray unit includes
a heating tray disposed above said lower lid and said soleplate in a stack,
an upper lid covering a top side of said heating tray and cooperatively defining said upper vaporization chamber with said electrical heating tray, and
an electrical heating tube disposed in said heating tray and able to generate heat from electricity flowing therethrough; and

wherein said heating tray has a bottom rib extending in a serpentine manner and protruding from a bottom of said heating tray to abut against said lower lid for surrounding said auxiliary vaporization region of said lower vaporization chamber.

6. The steam type clothing flattening device as claimed in claim 5 , wherein:
said upper lid is formed with a water inlet extending therethrough for introduction of water into said upper vaporization chamber; and
said upper vaporization chamber has a heating region extending along a longitudinal direction of said heating tray and having an end connected to said water inlet, and a main vaporization region extending and connected between another end of said heating region and said discharge port.
