Abstract
In a hydrogen production apparatus, a front end of a housing is closed by an opening/closing door. In a closed state of the opening/closing door, the upper end of the upper rod and the lower end of the lower rod in the opening/closing switching mechanism are disposed behind the first front frame piece and the second front frame piece of the housing, respectively. The axial distance between the upper end of the lower collar member and the second stopper is greater than the axial distance between the upper end of the upper collar member and the first stopper.
Claims9
A hydrogen production apparatus comprising:
- a water electrolysis unit that electrolyzes water to generate hydrogen gas;
- a storage unit that stores the hydrogen gas generated in the water electrolysis unit;
- a supply unit that supplies the hydrogen gas stored in the storage unit, to outside;
- an electrical unit that controls operation of at least the water electrolysis unit;
- and a housing that houses the water electrolysis unit, the storage unit, the supply unit, and the electrical unit,
- wherein:
- the housing comprises at least an upper frame disposed on an upper side of the housing in a height direction thereof and a lower frame disposed on a lower side thereof in the height direction, and includes an opening end opened in a lateral direction orthogonal to the height direction;
- and
- the housing further includes:
- an opening/closing door rotatably supported on the housing and configured to open and close the opening end;
- and
- a locking mechanism disposed on the opening/closing door and configured to restrict an opening operation of the opening/closing door with the opening end being closed;
- and
- wherein:
- the locking mechanism includes first and second rods configured to move along a height direction of the opening/closing door orthogonal to an opening direction of the opening end;
- in an opening operation restricted state in which the opening end is closed by the opening/closing door and the opening operation of the opening/closing door is restricted by the locking mechanism, an upper end of the first rod is disposed on an opposite side of the upper frame from the opening/closing door, and a lower end of the second rod is disposed on an opposite side of the lower frame from the opening/closing door;
- in the opening operation restricted state, a first enlarged diameter portion formed in a vicinity of the upper end of the first rod and enlarged in diameter radially outwardly is in a state of being inserted into a first guide portion disposed on the opening/closing door and extending in a direction opposite to the opening direction of the opening end, and a second enlarged diameter portion formed in a vicinity of the lower end of the second rod and enlarged in diameter radially outwardly is in a state of being inserted into a second guide portion disposed on the opening/closing door and extending in the direction opposite to the opening direction of the opening end;
- and
- an axial distance between an upper end of the second enlarged diameter portion and the second guide portion is larger than an axial distance between a lower end of the first enlarged diameter portion and the first guide portion.
