The present technology relates to a toilet set structure for an aircraft lavatory unit.
A toilet installed in an aircraft lavatory unit adopts a system of sucking waste in a toilet body into a discharge pipe by negative pressure. The shape of the toilet body is remarkably different from a toilet body including a bowl portion for a residential building, has a simple bowl shape, and is made of metal or a resin.
Thus, the toilet installed in the aircraft lavatory unit has a bowl-shaped toilet body supported by a support portion above a floor and is provided with a shroud that covers the toilet body and the support portion.
FIG. 1 is an explanatory diagram of a toilet in a side view, from which a part of a peripheral wall portion is removed.
FIG. 2 is a diagram of the toilet in a state in which a user sits on the toilet seat in a side view, from which a part of the peripheral wall and an outer plate portion of a toilet seat are removed.
FIG. 3 is a plan view of the toilet from which a lid is removed.
Next, embodiments of the present technology are described with reference to the drawings.
First, a first embodiment is described with reference to FIGS. 1 to 6.
As illustrated in FIGS. 1 to 4, a toilet 14 installed in an aircraft lavatory unit 10 in a lavatory 12 includes a toilet body 16, a support portion 18, a shroud 20, a toilet seat 22, a lid 24, and a cushion block 26.
