Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuation of U.S. application Ser.
No. 14/471,710, filed on Aug. 28, 2014, which claims the benefit
under 35 U.S.C. .sctn.119(b) of Chinese Patent Application No.
201420351344.2, filed Jun. 27, 2014, which is being incorporated by
reference in its entirety.
BACKGROUND OF THE INVENTION
[0002] The present invention relates to an electrical ironing
press.
[0003] Electrical ironing press is a kind of household electrical
appliances for daily use. It brings much convenience to our lives.
An electrical ironing press contains a large iron board capable to
heat up and dry up several pieces of textile products having large
surface areas at the same time. An example of textile products
having large surface areas is a quilt. Also, the electrical ironing
press can be adjusted to various different temperatures according
to practical needs. Some advanced electrical ironing presses are
equipped with steaming function.
[0004] Nowadays, an ironing press rotation mechanism of an existing
electrical ironing press usually achieves compression self-locking
by using a single spring. In this case, only one single spring is
compressed. Since the spring is positioned in the middle, the angle
of rotation is narrow and usually will not exceed 50 degrees due to
the constraints imposed by compression self-locking and the
position of the spring. Due to narrow opening angle of the iron
board, it is not convenient for users to move the textile products
on the iron board. When users put their hands or arms near to the
inner side of the iron board, they may touch the hot iron board and
get hurt.
[0005] Furthermore, those existing electrical ironing presses
equipped with steaming function give out only a fixed amount of
steam. The amount of steam cannot be adjusted, thereby depriving
the users of their rights to freely choose the amount of steam they
require. Time and energy are wasted when a large amount of steam is
in fact not required.
BRIEF SUMMARY OF THE INVENTION
[0006] In view of the inconvenience during use due to the
insufficient opening angle of the iron board of the ironing press,
the present invention provides an electrical ironing press which is
adjustable with respect to the amount of steam given out and which
has an iron board capable to open with a wider opening angle. The
present invention adopts the following technical proposal:
[0007] An electrical ironing press comprises a meshed board and an
iron board. The meshed board is fixedly connected with a base. The
iron board is fixedly connected with a rocker arm. The base is
hinged with the rocker arm. The rocker arm is provided with a steam
pipe. The electrical ironing press also comprises a spring and link
rods. The spring is connected with the rocker arm and the base and
positioned therebetween. An end of each of the link rods is hinged
with the base; another end of each of the link rods is slidably
connected with the rocker arm.
[0008] The electrical ironing press also comprises a locking device
for locking the link rods.

DETAILED DESCRIPTION OF THE INVENTION
[0024] The present invention will be further described in detail
below with reference to some embodiments and the accompanying
drawings. The embodiments and the detailed description below are
only intended to explain the present invention but not intended to
limit the scope of the present invention.
Embodiments
[0025] As shown in FIGS. 1-6, an electrical ironing press comprises
a meshed board 18 and an iron board 15. The meshed board 18 is
fixedly connected with a base 1. The iron board 15 is fixedly
connected with a rocker arm 2. The rocker arm 2 can be fixedly
mounted with a handle 9 via screws to facilitate operation. A first
shaft 5 is provided on the base 1. The base 1 is hinged with the
rocker arm 2 via the first shaft 5. The rocker arm 2 is also
provided with a steam pipe. The electrical ironing press also
comprises a spring 7 and link rods 3. The base 1 is also provided
with a second shaft 6. The rocker arm 2 is also provided with a
third shaft 8. The spring 7 is connected with the rocker arm 2 and
the base 1 and positioned therebetween via the second shaft 6 and
the third shaft 8. An end of each of the link rods 3 is hinged with
the base 1 to form a rotational end; another end of each of the
link rods 3 is slidably connected with the rocker arm 2 to form a
slidable end. In this embodiment, quantity of the link rods 3 is
two. The two link rods 3 are disposed on two sides of the rocker
arm 2 respectively. A connecting rod 4 is provided between the two
link rods 3 to stabilize the two link rods 3. The rocker arm 2 is
also provided with a locking device capable to lock the link rods
3. Positions of the rotational end of each of the link rods 3 and
the slidable end of each of the link rods 3 are interchangeable.
The locking device may also be provided at the base 1. The steam
pipe is also provided with steam regulating device. The rocker arm
2, the steam pipe, the link rods 3, the locking device and the
steam regulating device can be mounted inside a shell formed by an
upper shell 16 and a lower shell 17.
[0026] In another modified embodiment, the spring 7 is an air
spring.
[0027] According to the embodiments described above, when the
rocker arm 2 opens up to its widest opening angle (approximately 80
degrees), the slidable ends of the link rods 3 displace with
respect to the rocker arm 2 and the support torque generated by the
air spring is equal to the total gravity torque of all the moved
parts, thereby maintaining the rocker arm 2 at an equilibrium at
the widest opening angle. During the process of opening and
closing, supporting force of the air spring varies along with the
external force being exerted; therefore, unlike an abrupt variation
of force at the widest opening angle when a normal spring 7 is
used, variation of force on the handle 9 is very small when an air
spring is used.
[0028] According to the locking device of the present invention,
the link rods 3 are provided with locking holes. The locking device
comprises a first knob 11, a cam wheel 10 and retractable rods 19.
The first knob 11 is disposed on a shell outer surface and is
connected with the cam wheel 10. The first knob 11 and the cam
wheel 10 are co-axial and rotate at the same speed when they
rotate. The retractable rods 19 abut against the cam wheel 10. As
shown in FIG. 5, in an unlocked condition of the link rods 3, the
retractable rods 19 on two sides abut in a direction towards each
other against two ends of the minimum diameter of the cam wheel 10
respectively under the effect of springs 20, and the retractable
rods 19 are away from the locking holes of the link rods 3. As
shown in FIG. 6, when the first knob 11 rotates, the first knob 11
also drives the cam wheel 10 to rotate at the same speed; as the
cam wheel 10 rotates, its diameter whose two ends are abutted
against and slidably in contact with the retractable rods 19
increases, thereby pushing the retractable rods 19 outwardly to two
sides and into the locking holes. The first knob 11 is therefore
used for controlling insertion of the retractable rods 19 into the
locking holes to lock the link rods 3; in a locked condition of the
link rods 3, the rotational ends of the link rods 3, the first
shaft 5 and the retractable rods 19 form a fixed triangular fixing
mechanism for link rods, ensuring that the entire electrical
ironing press can be lifted up by only lifting up the handle 9.
Quantity of locking holes on each of the link rods can be more than
one. By inserting the retractable rods 19 into different locking
holes, the rocker arm 2 can be locked at different opening
angles.
[0029] According to the steam regulating device of the present
invention, the steam regulating device comprises a second knob 12,
a gear 13 and a steam regulating valve 14. The second knob 12 is
disposed on the shell outer surface and engages with the gear 13.
The gear 13 sleeves on outer side of the steam regulating valve 14
so as to connect with the steam regulating valve 14. The steam
regulating valve 14 is mounted above the steam pipe. When the
second knob 12 is rotated, the gear 13 engaged with the second knob
12 rotates synchronously with the same magnitude, and the gear 13
also drives the steam regulating valve 14 to rotate; the amount of
steam given out from an output end of the steam pipe is therefore
controlled by the second knob 12.
[0030] In another modified embodiment, the first knob 11 and the
second knob 12 are co-axial. In particular, a central shaft is
connected at a bottom part of the first knob 11. The first knob 11
is mounted on the rocker arm 2 via the central shaft. The cam wheel
10 is fixed at a bottom end of the central shaft. The second knob
12 is in a ring shape and is disposed around outer side of the
first knob 11. A bottom part of the second knob 12 is connected
with a hollow shaft. The hollow shaft is disposed around outer side
of the central shaft. Length of the hollow shaft is slightly
shorter than length of the central shaft. A bottom end of the
hollow shaft engages with the gear 13. The cam wheel 10 and the
gear 13 are positioned at different heights so that they do not
affect each other. Therefore, the locking device and the steam
regulating device are independent from each other and do not
interfere with each other. Periphery of the second knob 12 can be
provided with a press cover to prevent the second knob 12 from
disengagement. In this embodiment, positions of the first knob 11
and the second knob 12 are interchangeable; in other words, the
first knob 11 can be positioned around outer side of the second
knob 12, while other structures remain substantially similar.
[0031] Various parts of the present invention described above are
assembled as follows: assemble the air spring, the second shaft 6
and the base 1 first, and then assemble the rocker arm 2, the first
shaft 5 and the base 1; in a condition which no force is exerted to
the air spring, use the third shaft 8 to connect the air spring and
the rocker arm 2 and then mount the link rods and the connecting
rod 4; after that, mount the gear 13 on the steam regulating valve
14 (the steam regulating valve 14 and the handle 9 are
pre-installed on the rocker arm 2), and then mount the lower shell
17, the second knob 12, the iron board 15, the upper shell 16 and
the first knob 11 in sequential order. The most important operation
of the electrical ironing press by users is to operate the function
buttons on the control panel; the lesser important operation of the
electrical ironing press by users is to turn the second knob 12 to
regulate the amount of steam; a minimum amount of steam is given
out when the second knob 12 is turned to the farthest left; a
maximum amount of steam is given out when the second knob 12 is
turned to the farthest right. When it is not necessary to use the
electrical ironing press, turn the first knob 11 in a clockwise
direction by 90 degrees so that the retractable rods 19 are
inserted into the link rods 3 to lock the rotation of the rocker
arm 2; as such, the electrical ironing press can be carried easily.
When it is necessary to use the electrical ironing press, turn the
first knob 11 in an anti-clockwise direction by 90 degrees so that
the retractable rods 19 disengage from the link rods 3 to allow
rotation and opening of the rocker arm 2.
[0032] The present invention is described in detail above according
to some embodiments. Specific examples have been used for
explaining the implementation and principles of the embodiments of
the present invention. The above description is only intended to
assist in understanding the principles of the embodiments of the
present invention. It should be noted that a person skilled in this
field of art may make changes in respect of specific implementation
and the scope of application according to the teaching of the
embodiments of the present invention. In essence, the above
description should not be understood as having any limiting effect
on the present invention.
