DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an iron provided with a liquid crystal display device.

[0002]

2. Description of the Related Art Conventional irons generally use LED lamps as indicators (Japanese Utility Model Publication No. 63-8399).
LED lamps consume a relatively large amount of current.
If the lamps are turned on at the same time, the power consumption of the DC power supply increases, so the DC power supply circuit needs to be enlarged. Since irons are required to be small and light in order to improve operability, if the power supply circuit is large, the condition of small and light cannot be satisfied. In order to solve this problem, it is conceivable to use a liquid crystal display element with low power consumption for the display. However, the liquid crystal display element is L
Unlike ED lamps, they do not emit light by themselves, so the range in which the display can be seen clearly (viewing angle) is limited, and it is suitable for viewing from a fixed angle like a calculator, but it is horizontal like an iron When mounting on an object which is used in a state where it is suspended in an oblique or vertical state, there is a concern that if the mounting position is incorrect, the display becomes difficult to see.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and uses a liquid crystal display element as a display to suppress the power consumption of a DC power supply, reduce the size of the power supply, and reduce the size of the power supply. The present invention provides an iron that makes it easy to see the display of the liquid crystal display element even in various use states.

[0004]

In the iron of the present invention, a liquid crystal display element is disposed near a grip portion at an angle of forward and downward with respect to a base surface.

[0005]

Since the present invention is constructed as described above, the display of the liquid crystal display element in a state where the iron is horizontal and inclined is easy to see, and the base surface is vertical or slightly inclined backward, and is in a self-standing state. In this case, the liquid crystal display element is maintained in a state in which the liquid crystal display element is tilted slightly forward from the vertical direction so that the display can be easily viewed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described by taking a cordless iron as an example.
(2) Ascend the iron body (1) forward (about 20 degrees)
A power supply is supplied from the stand (2) to the iron body (1) at the time of mounting. In the iron body (1), (3) is a base in which a heater is embedded, (4) is a base cover, (5) is a handle fixed to the base cover (4), and (6) is a handle (5). (7) a hollow grip that is integrally provided and is long in the front-rear direction
Is a detachable water tank. (8) a printed circuit board on which various electronic components are mounted and arranged in the space of the grip portion (6);
(9) is upper and lower glass plates (10) as shown in FIG.
(11) A liquid crystal display element in which liquid crystal is injected between the liquid crystal display elements and the periphery of the liquid crystal display element is sealed. The lower glass (11) is made longer in the front-rear direction than the upper glass (10), and the protruding portion is formed by a nail ( 13) and (14). The holding table (12) holds the liquid crystal display element (9) on the printed circuit board (8) with claws (15), (15), and (4) so that the liquid crystal display element (9) is inclined downward (about 10 degrees) with respect to the lower surface of the base (3). (15). The upper surface of the liquid crystal display element (9) faces the upper surface of the grip (6) and is covered by a transparent window member (16).

A microcomputer 17 controls the temperature of the base 3 and drives the liquid crystal display element 9 and is soldered to the lower surface of the printed circuit board 8 as shown in FIG. 2B. The microcomputer (17) is operable by a backup power supply (not shown) even while the iron body (1) is detached from the stand (2). (18) is a flexible wiring board in which a copper foil pattern is sandwiched between polyimide films, and a group of copper foil patterns (19) in which a liquid crystal drive terminal group of a microcomputer (17) is soldered around a front end of a printed circuit board (8). ) And the terminal group of the liquid crystal display element (9). Here, since the copper foil pattern group (19) is formed in the longitudinal direction of the printed board (8), the width of the printed board (8) does not need to be increased, and the width of the grip (6) increases. It is possible to prevent a situation in which it is difficult to grasp. (20) is a temperature setting switch, and (21) is a button for pressing this switch.

Here, the liquid crystal display element (9) will be briefly described. Usually, the liquid crystal display element (9) has a viewing angle of about 30 degrees in the left-right direction with respect to the perpendicular (s), and in the front-rear direction, one side has a relatively wide viewing angle of about 45 degrees, while the other side has a relatively wide viewing angle. The viewing angle is as narrow as about 30 degrees.
Then, the display looks sharp within the above-mentioned viewing angle, but when it deviates from it, it becomes suddenly difficult to see. The liquid crystal display element (9) has a rectangular planar shape, and its longitudinal direction is oriented in the same direction as the longitudinal direction of the grip portion (6), and the liquid crystal display element (9) is arranged such that the side having a wide viewing angle is the rear side of the iron. ing. That is, the viewing angle in the front-back direction is perpendicular to the liquid crystal display element (s).
It is arranged so that the rear side of the grip is larger than the front side of the grip. As shown in FIG. 1, the iron body (1) is supported by a stand (2) at an angle of 20 degrees in front of the front, and the liquid crystal display element (9) is a base (3).
It is supported at an angle of 10 degrees in front of
When the iron body (1) is placed on the stand, the liquid crystal display element (9) is inclined at an angle of about 10 degrees in front of the reference plane (m), so that the operator can view the display obliquely from above and behind. This is the most easily viewable angle.

During ironing, as shown in FIG. 3, the liquid crystal display element (9) has an angle of about 10 degrees forward and downward with respect to the reference plane (m). Therefore, a clear view can be seen by adjusting the range of the viewing angle to the operator who is obliquely viewed from above while ironing.

On the other hand, when the iron main body (1) stands alone at a place other than the stand (2) during ironing and takes a short break, the base (3) as shown in FIG.
Is more than 90 degrees in front of the reference plane (m). Here, assuming that the liquid crystal display element (9) is arranged in parallel with the base (3), the line (s') perpendicular to the upper surface of the liquid crystal display element (9) has a downward angle. The range of the corner is also generally downward. As a result, the liquid crystal display element
In order to clearly view (9), the head must be lowered and the position of the eyes must be considerably lowered, and the display becomes difficult to see.
However, since the liquid crystal display element (9) is arranged at an angle of forward descent with respect to the base (3), the iron body (1)
4 can be set so that its perpendicular (s) is parallel or upward to the reference plane (m) as shown in FIG. Therefore, the range of the viewing angle can be made upward as a whole, and unnecessary operations such as lowering the head to clearly view the display of the display element (9) can be reduced.

The above embodiment has been described by taking a cordless iron as an example. However, the present invention is not limited to this and can be applied to an iron with a cord.

[0012]

As described above, the iron according to the present invention is a liquid crystal display element which faces the upper surface of the grip portion which is long in the front-rear direction and whose longitudinal direction is provided in the same direction as the grip portion. Because it is arranged in the longitudinal direction of the base surface with an angle of forward descent with respect to the base surface, the iron is horizontal, diagonal,
The display of the liquid crystal display element can be seen clearly even in the case of being placed in various states such as self-reliance, and the operability at the time of ironing can be improved. Further, power consumption of the display portion can be significantly reduced as compared with the case where an LED lamp is used, so that the power supply circuit can be reduced in size and weight. for that reason,
If applied to a cordless iron, operability can be improved by making the backup power supply smaller and lighter.
