Description
TECHNICAL FIELD
[0001] The present invention relates to a special effect
four-dimensional (4D) chair provided with wind blowing and hot air
functions and a special effect system including the same.
BACKGROUND ART
[0002] The 4D technique refers to a technique which gives a sense
of reality to movie viewers by providing physical effects (spray of
water bubbles, vibration or movement of a seat, strobe lights,
emission of smell and the like) together with 3D stereoscopic
images. Although it is generally referred to as 4D in the sense
that a technique is added to the 3D, this is a kind of marketing
terminology rather than a technical terminology. The 4D technique
is not necessarily accompanied by a 3D stereoscopic image, and when
an image needs to be played in a 4D facility although the image
itself is manufactured as a general image, not a 3D stereoscopic
image, it can be implemented by providing physical effects to a 2D
general image. Accordingly, the most outstanding feature of the 4D
technique is giving a physical stimulus to the audience in addition
to the image.
[0003] Recently, the 4D technique reaches the level of making the
audience visually, acoustically and olfactorily feel a situation
close to a real situation when the audience watch a movie, and a
tactile effect using hot air is also developed.
[0004] However, a conventional technique using hot air is a method
of discharging the hot air from the cushion of the backrest of a
front chair to a back chair. Since temperature of the hot air
rapidly drops from the moment of discharging the hot air through
the outlet due to the distance between the front chair and the back
chair, a heating element which generates heat requires high power
in order to obtain a high hot air effect, and a wind blower which
generates wind also requires high power. In addition, since noises
are generated by the rotation speed of a fan which rotates faster
if power consumption of the wind blower is higher, excessive noise
in feeling the hot air rather hinders the audience from enjoying
the movie.
[0005] Accordingly, when the hot air function is used, the cost
increased by using the power for the effect of hot air is larger
than the profit of playing the movie in a theater, and thus using
the 4D effect of hot air in a theater is avoided.
[0006] In addition, since the distance between a front chair and a
back chair is not standardized for all theaters and differently
applied in each country and theater, it is inconvenient in that the
heating element, the wind blower and the like should be adjusted
and controlled according to the distance between the front chair
and the back chair in order to provide an adequate effect of hot
air to a viewer seated in the back chair. Particularly, since the
distance between the front chair and the back chair is further
extended recently for the convenience of viewers, the cost of using
the power according to the effect of hot air is expected to be
increased furthermore, and thus the 4D technique is difficult to be
commercialized in a country adopting a wide distance between the
front chair and the back chair.
[0007] On the other hand, seeing from the aspect of stability, the
conventional technique mounts a temperature sensor (bimetal) in the
neighborhood of a hot air module, and if temperature goes above a
predetermined level, the temperature sensor operates and cuts off
the power. At this point, if a defect occurs in the temperature
sensor, there is a high risk of fire since temperature of the
heating element cannot be controlled.
[0008] Accordingly, although the effect of hot air is an essential
factor for feeling various 4D effects, there are obstacles
described above to reach the level of commercialization.
DISCLOSURE
Technical Problem
[0009] Therefore, the present invention has been made in view of
the above problems, and it is an object of the present invention to
reduce the cost of installing and using 4D chairs in a theater by
reducing the power needed for generating hot air.
[0010] In addition, another object of the present invention is to
reduce the noise of rotation of a fan which hinders watching a
movie by making it possible to obtain a sufficient effect of hot
air although the speed of the fan is lowered and provide the
audience with comfort by providing an adequate strength of hot air
when the audience feel the hot air.
[0011] In addition, another object of the present invention is to
lower the manufacturing and maintenance cost of the 4D effect
chairs by miniaturizing and simplifying a module for generating a
hot air effect and secure more space in a chair to mount different
visual, acoustic, olfactory and vibratory effects on the chair.
[0012] In addition, another object of the present invention is to
prevent breakout of a fire more effectively by using the resistance
switching characteristics of a material itself which generates
heat, without installing and controlling a temperature sensor.
Technical Solution
[0013] To accomplish the above objects, according to one aspect of
the present invention, there is provided a special effect chair
including: a chair; a heating element installed inside the chair; a
wind blowing unit for circulating air heated by the heating
element; and a discharge unit for discharging the air circulated by
the wind blowing unit to the outside of the chair, and the
discharge unit is positioned on the front side of the chair and may
include an air vent blade for controlling the direction or the
amount of the discharged air.
[0014] In addition, in the special effect chair of the present
invention, the heating element may be formed of a material which
abruptly increases a resistance value at a specific temperature or
higher, and the heating element includes a PTC heater. In addition,
the special effect chair may further include a switch for
controlling operation of the heating element or the wind blowing
unit.
[0015] In addition, the special effect chair of the present
invention may further include a heat storage unit for conserving
the air heated by the heating element, and the heat storage unit
may be combined on the surface of the heating element or may have a
shape surrounding the heating element.
[0016] In addition, the special effect chair of the present
invention includes: a seat unit; a base unit for supporting lower
part of the seat unit; and a backrest combined with the seat unit
or the base unit and formed to be extended upward, and the
discharge unit may be positioned on the front side of the
backrest.
[0017] Here, the discharge unit may be positioned at an upper
portion on the front side of the backrest, and the heating element
may be arranged inside the backrest, between the center portion of
the backrest and the upper portion where the discharge unit is
formed.
[0018] In addition, the special effect chair of the present
invention may further include an armrest combined at least at any
one side of the seat unit or the backrest, and the discharge unit
may be positioned in the armrest.
[0019] A special effect system of the present invention includes: a
special effect chair including a heating element installed inside
the chair, a wind blowing unit for circulating air heated by the
heating element, and a discharge unit for discharging the air
circulated by the wind blowing unit to the outside of the chair;
and a control server for controlling at least any one of the
heating element and the wind blowing unit of the chair.
Advantageous Effects
[0020] Compared with a conventional 4D chair which uses the hot air
effect, the present invention may reduce the power needed for
generating the hot air as much as about one twentieth from 2,000 W
to 100 W per unit of a 4D chair by reducing an injection distance,
miniaturizing a hot air generating module and using a heat storage
plate, and, accordingly, the cost of installing and using the 4D
chair in a theater can be reduced drastically.
[0021] In addition, the noise and power of a fan can be reduced
naturally by reducing the injection distance and miniaturizing the
hot air generating module, and since the hot air is injected at a
wind speed adequate for the audience to feel the hot air, an effect
of providing comfort can be obtained.
[0022] Meanwhile, since the heating element of the present
invention uses a material which abruptly increases the resistance
value at a specific temperature or higher, a temperature sensor
does not need to be additionally installed unlike the configuration
of a conventional technique, and thus the manufacturing cost is
reduced, and although the conventional technique has a risk of fire
caused by the defect or failure of the temperature sensor, the
present invention is more adequate for preventing a fire since the
stability of adjusting the temperature is rather higher although
the temperature sensor is not equipped.

MODE FOR INVENTION
[0030] The details for embodying the present invention will be
hereafter described with reference to the accompanying drawings. In
addition, in describing the present invention in detail, if related
already known functions are apparent to those skilled in the art
and may unnecessarily make the spirit of the present invention
unclear, detailed description thereof will be omitted.
[0031] FIG. 1 is a view showing the interior of a special effect
chair 100 according to an embodiment of the present invention, and
FIG. 2 is a view showing the structure of an assembly (hereinafter,
a combination of a heating element 120, a wind blowing unit 130, a
discharge unit 140 and a heat storage unit 150 is referred to as an
assembly) according to an embodiment of the present invention.
[0032] A special effect chair 100 according to an embodiment of the
present invention includes a chair 110, a heating element 120, a
wind blowing unit 130 and a discharge unit 140. More specifically,
the special effect chair 100 includes a chair 110, a heating
element 120 installed inside the chair 110, a wind blowing unit 130
for circulating air heated by the heating element 120, and a
discharge unit 140 for discharging the air circulated by the wind
blowing unit 130 to the outside of the chair 110, and the discharge
unit 140 is positioned on the front side of the chair 110.
[0033] The heating element 120 is installed inside the chair 110 to
heat up ambient air by generating heat. For example, a method of
converting electrical energy into heat energy such as a method of
generating heat using an electric resistor installed in an
electro-thermic appliance such as an electric iron or an electric
blanket can be used. However, the present invention is not limited
thereto, and any method which can generate hot air using electrical
energy can be applied.
[0034] The wind blowing unit 130 circulates the air heated by the
heating element 120. The wind blowing unit 130 is assembled by
combining a motor and a fan and generates wind as the fan is
rotated by the motor. Hot air is generated as the wind passes
through the heating element 120 or a heat storage unit 150. At this
point, hot air or normal wind can be selectively discharged
according to on and off of the heating element 120.
[0035] For example, when an explosion scene appears, the air is
heated by turning on the heating element 120 in advance and the hot
air is discharged by operating the wind blowing unit 130, and in a
scene of riding and driving a motorcycle fast, cool wind may be
blown by operating the wind blowing unit 130 without turning on the
heating element 120. This can be controlled by a control server 200
described below.
[0036] At this point, cold wind can be discharged by installing a
cooling module instead of the heating element 120. For example, a
method of cooling down ambient air by using a Peltier element can
be used. In addition, it is also possible to implement a
configuration of selectively discharging hot or cold air by
installing the cooling module together with the heating element 120
and controlling them by the control server described below.
However, the present invention is not limited thereto, and any
method which can generate cold air can be applied.
[0037] The discharge unit 140 means an outlet for discharging the
air heated inside the chair 110. The discharge unit 140 is
positioned on the front side of the backrest 113, and, in this
case, the viewer may feel, in the back, the hot air discharged from
the front side of the chair 110.
[0038] A conventional technique is a configuration which positions
the discharge unit 140 on the rear side of the chair 110, and the
viewer feels hot air discharged from the front chair 110. As shown
in the conventional technique, if it is assumed that the injection
distance of the hot air from the outlet to the viewer is one meter
and a degree of temperature drop is experimented (see FIG. 7), the
temperature measured one meter away from the outlet is 36 degrees
when the discharging temperature is 128 degrees, showing that a
large degree of temperature drop is occurred due to the external
temperature, and a very high power (2,000 W per unit) is required
in order to have the viewer feel the effect of hot air. However, in
the present invention, since the discharge unit 140 is positioned
on the front side of the chair 110 and the injection distance to
the body of the viewer is very short, an efficient hot air effect
can be obtained with low power (100 W per unit) and light wind
blowing, and thus the present invention has an effect of reducing
the power as much as one twentieth.
[0039] Accordingly, a component consuming low power can be used
since a sufficient effect can be obtained with low power compared
with a conventional technique in which the discharge unit 140 is
positioned on the rear side of a chair, and the burden of cost for
manufacturing and using the chair is lowered greatly as the cost of
other materials such as a connection pipe and the like is saved,
and the noise generated by the rotation of a fan can be reduced
since strong wind blowing is not needed. Furthermore, since a
heating element 120 and a fan of a further small size can be used
as it does not need to blow the hot air far, the assembly can be
miniaturized, and thus the space inside the chair 110 for mounting
other 4D techniques can be used efficiently.
[0040] The data comparing the difference of power and manufacturing
cost between the conventional technique and the present invention
according to the position of the discharge unit 140 is shown
below.
TABLE-US-00001 TABLE 1 Conventional technique Present invention
Power Heating AC 220 V/1,000 W AC 220 V/13 W consumption element
Fan AC 220 V/100 W.sup. DC 12 V/8 W
[0041] In another embodiment of the present invention, the heating
element 120 may use a material which abruptly increases the
resistance value at a specific temperature or higher. A Positive
Temperature Coefficient (PTC) heater is an example of the material,
and this is a kind of n-type semiconductor provided with electrical
conductivity by adding an extremely small amount of rare earth
element to Barium Titanate and capable of moving the Curie
temperature by substituting some of Ba with Sr or Pb, and this is
defined as an element having a property of abruptly increasing the
resistance value by phase transition if the temperature arrives at
a specific temperature.
[0042] Since the PTC element may maintain temperature to be
constant at a desired temperature on the basis of length and area,
it can be manufactured and used to have an area and a length for
maintaining the surface temperature at about 170 degrees when the
heating element 120 is installed in the backrest 113. However, the
above example is merely an example, and the present invention is
not limited thereto, and the PTC element can be manufactured to
have a different area and length in order to maintain a constant
temperature according the installation position of the heating
element 120. In addition, a material which can maintain a specific
temperature in a principle similar to this also can be applied to
the heating element 120.
[0043] Since the conventional method uses a material having a
constant resistance regardless of change of temperature and has a
risk of fire if the temperature continuously goes up, it uses a
method of attaching a temperature sensor to the heating element 120
and controlling temperature in a method of turning off the power of
the heating element 120 if it reaches a predetermined temperature.
Accordingly, since a temperature sensor is additionally attached,
the manufacturing cost is high, and there is a risk of fire caused
by overheating if the temperature sensor is out of order.
[0044] Contrarily, in the present invention, as the resistance
value abruptly increases at a specific temperature or higher, the
increased resistance value limits the current, and the temperature
is maintained almost constantly regardless of change of external
temperature or power voltage. Accordingly, in the present
invention, since the temperature can be controlled by the material
itself without attaching a separate temperature sensor,
installation cost can be reduced and, at the same time, the risk of
fire caused by the failure of the temperature sensor can be solved
by simplifying the structure compared with that of the conventional
technique.
[0045] In an embodiment of the present invention, the chair 110
includes a seat unit 111, a base unit 112 and a backrest 113.
[0046] The seat unit 111 is a portion contacting with the buttocks
when a viewer is seated, and the base unit 112 supports the lower
part of the seat unit 111. The backrest 113 is combined with the
seat unit 111 or the base unit 112 and formed to be extended upward
to support the back and the head of the viewer. In addition, an
armrest 114 may be combined at least at any one side of the seat
unit 111 or the backrest 113 to support arms or put a beverage,
popcorns or the like thereon when the viewer watches a movie.
[0047] At this point, the discharge unit 140 may be positioned on
the front side of the backrest 113 (see FIG. 4), and if the
discharge unit 140 is positioned on the front side of the backrest
113, an effective hot air effect can be obtained with low power and
light wind blowing since the injection distance to the body of the
viewer is very short. Accordingly, the burden of cost can be
lowered since a sufficient effect can be obtained with low power
compared with a conventional technique in which the discharge unit
140 is positioned on the rear side of a chair, and the noise
generated by the rotation of a fan can be reduced since strong wind
blowing is not needed. Furthermore, since a heating element 120 and
a fan of a further small size can be used as it does not need to
blow the hot air far, the overall configuration of the hot air
effect function can be miniaturized, and thus the space inside the
chair 110 for mounting other 4D techniques can be used
efficiently.
[0048] Particularly, since the discharge unit 113 is positioned at
an upper portion on the front side of the backrest 113 and the
heating element 120 is arranged inside the backrest 113, between
the upper center portion of the backrest 113 and the upper portion
where the discharge unit 140 is formed, the distance of injecting
the hot air is reduced, and, at the same time, the configuration of
the hot air effect function can be miniaturized furthermore by
placing the discharge unit 113 and the heating element 112 as close
as possible.
[0049] In addition, in another embodiment of the present invention
(see FIG. 3), the chair 110 further includes an armrest 114
combined at least at any one side of the seat unit 111 or the
backrest 113, and the discharge unit 140 may be positioned in the
armrest 114. Accordingly, the hot air effect can be provided toward
the viewer from the armrest 114 (see FIG. 5), and the viewer may
feel a further intensive hot air effect by installing a plurality
of the assemblies at different portions.
[0050] The position, the size and the shape of the discharge unit
140 are merely an example and can be applied as various
embodiments, and the discharge unit 140 can be provided in both of
the backrest 113 and the armrest 114 (see FIG. 6).
[0051] In another embodiment of the present invention, the
discharge unit 140 may include air vent blades for controlling the
direction or the amount of the discharged air. For example, the air
vent blades are combined at both edges of the discharge unit 140
hole so that the blades can be adjusted up and down or left and
right, and the blades can be adjusted to be engaged with each other
to block the discharge unit 140 so that the air cannot be
discharged. However, the present invention is not limited thereto,
and any method which can control the direction and the amount of
the wind can be applied. In this method, the amount of wind can be
adjusted by using the air vent blades if the viewer does not want
the effect of hot air.
[0052] In another embodiment of the present invention, the chair
110 may further include a heat storage unit 150 for conserving the
air heated by the heating element 120. The heat storage unit 150 is
for conserving the air heated by the heating element 120, which can
efficiently conserve the heat by adopting a structure continuously
winding at regular intervals (see FIG. 2) by using a metallic
material which can easily absorb heat to form multiple layers of a
structure which can store air between metals. At this point,
aluminum or the like can be used as a material for easily
conserving and discharging heat.
[0053] If the heat storage unit 150 is used, it is possible to
configure an embodiment of a structure, in which the heat storage
unit 150 combined with the heating element 120 receives the heat
generated by the heating element 120 placed inside the chair 110
and heats up and conserves the air, and the air heated and
conserved by the heat storage unit 150 is immediately circulated
toward the discharge unit 140 if the wind blowing unit 130
operates, and if the hot air is discharged through the discharge
unit 140 positioned on the front side of the chair 110, the viewer
feels the effect of hot air. Like this, if the heat storage unit
150 is used, power can be saved since the air is heated in advance
and the heated air is stored.
[0054] Particularly, the heat storage unit 150 may be directly
combined on the surface of the heating element 120, or a structure
of enhancing the efficiency by placing the heat storage unit 150
within the intervals of a superior heat conductivity range may be
adopted although the heat storage unit 150 does not contact with
the surface, or the heat storage unit 150 may adopt a configuration
surrounding the heating element 120 in the shape of a circle or a
sphere by placing the heat element 120 at the center. If the heat
storage unit 150 surrounds the heating element 120 in the shape of
a sphere, the most ideal heat transfer method can be adopted since
the distance from the heating element 120 to the heat storage unit
150 is the same in any direction of x, y or z axis.
[0055] In still another embodiment of the present invention (see
FIG. 3), the chair 110 may further include a switch 160 for
controlling operation of the heating element 120 or the wind
blowing unit 130. The switch 160 may turn on or turn off the hot
air effect by controlling operation of the heating element 120 or
the wind blowing unit 130. The switch 160 can be placed at any
position where the viewer may easily handle the switch and is
connected to the heating element 120 and the wind blowing unit 130
to perform a function of blocking or supplying power. The effect
obtained by installing the switch 160 is that, for example, a
viewer may want cool wind rather than hot air when the temperature
is high like in summer, and, in this case, if the viewer turns off
the heating element 120 by himself or herself, the viewer may feel
cool wind instead of hot air since only the wind blowing unit 130
operates. In addition, a viewer who does not want the hot air or
wind blowing functions at all may cut off the hot air or wind
blowing functions by turning off the wind blowing unit 130 or both
the heating element 120 and the wind blowing unit 130. In addition,
the switch 160 may control the direction of wind or the amount of
the discharged wind by controlling the air vent blades.
[0056] In addition, in another embodiment of the present invention,
a configuration of conserving heat can be adopted by employing a
configuration of installing the assembly inside a case formed of a
metallic material.
[0057] Meanwhile, a special effect system includes a special effect
chair 100 and a control server 200.
[0058] The special effect chair 100 includes a heating element 120
installed inside a chair 110, a wind blowing unit 130 for
circulating air heated by the heating element 120, and a discharge
unit 140 for discharging the air circulated by the wind blowing
unit 130 to the outside of the chair 110, and the discharge unit
140 is positioned on the front side of the chair 110. At this
point, the special effect chair 100 may include a communication
unit to be controlled by the control server and can be connected to
the control server through a wired or wireless local area network
and controlled by the control server.
[0059] The control server 200 controls at least any one of the
heating element 120 and the wind blowing unit 130 of the special
effect chair 100. All the settings of operating the special effects
of a movie, the settings for determining a time for operating or
turning off the heating element 120 and the wind blowing unit 130
at every required time, are stored in the memory of the control
server. Accordingly, since each component of the special effect
chair 100 is controlled according to the previously set control
time after a movie starts to play, all the special effect chairs
100 can be controlled simultaneously, or they can be controlled
manually if needed.
[0060] For example, all the special effect chairs 100 in a theater
can be simultaneously controlled to automatically realize the hot
air and wind blowing effects at a synchronized time while a movie
is actually played by previously storing a setting of discharging
hot air by operating the wind blowing unit 130 (49 minutes 59
seconds) after heating the air by operating the heating element 120
in advance when an explosion scene (50 minutes 00 second) appears,
a setting of blowing cool wind by operating the wind blowing unit
130 (29 minutes 59 seconds) without turning on the heating element
120 in a scene of riding and driving a motorcycle fast (30 minutes
00 second), and other settings.
[0061] In addition, the special effect chair 100 of the special
effect system can be applied as shown in the configurations of the
various embodiments described above.
[0062] It will be understood by those skilled in the art that the
present invention may be embodied in other specific forms without
departing from the spirit and essential characteristics thereof.
Accordingly, it should be understood that the above-described
embodiments are only exemplary, but are not restrictive from any
standpoint, that the scope of the present invention is defined by
the accompanying claims, rather than the above detailed
description, and that the meaning and scope of the claims and all
changes and modifications derived from equivalents thereof should
be interpreted as being included in the scope of the present
invention.
