Technical Field
[0001] This utility model relates to the field of household appliances, and specifically,
to a steam iron.
Related Art
[0002] Steam irons have become one of commonly used household appliances. Steam can be jetted
out from an ironing board of an electrical steam iron, and is used to humidify ironed
clothes, to prevent the clothes from being damaged due to overheat. In the prior art,
an electrical steam iron includes a water tank and a steam chamber; the steam chamber
is formed above an ironing board; and after flowing into the steam chamber, water
in the water tank is heated by the ironing board and evaporates into steam that jets
from a jetting hole of the ironing board. Steam jetting amount generally can be adjusted.
Amount of water flowing from the water tank to the steam chamber is controlled, so
as to control amount of generated steam. "Close", "large", and "small" gears may be
set according to requirements, and controlled by using a water quantity adjusting
device, such as a knob or a toggle, to achieve control of steam amount.
[0003] After the steam iron is used for a long time, some dirt deposits in the steam chamber,
such as a calcium compound, and therefore the steam chamber needs to be cleaned. Generally,
the steam chamber is washed by using relatively large water flow in the water tank.
In the prior art, generally, a cleaning function is controlled by using an independent
button.
[0004] However, steam control and cleaning control are respectively achieved by using two
systems that are independent from each other, and consequently, a structure of an
electrical iron becomes complex, and production costs increase; and operation complexity
also increases because the two systems need to be operated separately.
[0005] Currently, effective solutions have not been proposed to solve problems, such as
complex structures, high costs, and inconvenient operation that are caused by independence
of a steam control device from a cleaning device, of steam irons in the prior art.
SUMMARY
[0006] This utility model provides a steam iron, to solve at least problems, such as complex
structures, high costs, and inconvenient operation that are caused by independence
of a steam control device from a cleaning device, of steam irons in the prior art.
[0007] To solve the foregoing problems, one aspect of this utility model provides a steam
iron, having an iron body, a water tank, and a steam chamber connected with the water
tank, the steam chamber being provided thereon with a water opening; the iron body
being provided thereon with a water quantity adjusting device that controls flowing
from the water opening to the steam chamber, where the water quantity adjusting device
includes a valve rod and a toggle; the toggle is provided with a handle and a groove
matching a top end of the valve rod; and when the handle rotates to a different position,
the toggle moves the valve rod to the different position along an axial direction
of the valve rod by contacting a tray on the valve rod, and adjusts water flow at
the water opening by controlling a size of a gap between the valve rod and the water
opening. The valve rod is controlled to move up and down by toggling the handle on
the water quantity adjusting device, so that the size of the gap between the valve
rod and the water opening changes accordingly, thereby changing a size of water flow
from the water tank to the steam chamber, for example, achieving switch among a no-steam
mode, a small-steam amount mode, a large-steam amount mode, and a large-water amount
mode.
[0008] Preferably, a tail end of the valve rod is provided with a side notch configured
to control the water flow. Water flow control is achieved by coordination between
the side notch provided on the tail end of the valve rod and working gears of the
