Description

A special effect chair and a system including the same

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a special effect 4D chair equipped with a blowing function and a hot air function, and a special effect system including the chair.

4D technology refers to a technology that adds realism to movie audiences by providing physical effects (water droplet ejection, seat vibration and movement, flash light, smell diffusion, etc.) with 3D stereoscopic images. It is generally called 4D in the sense that one technology has been added to 3D, but it is a kind of marketing term rather than a technical term. 4D technology does not necessarily have to accompany 3D stereoscopic images. The 3D stereoscopic images are not necessarily 3D stereoscopic images, but they can be realized by providing physical effects to 2D stereoscopic images when they are to be displayed in a 4D facility. Therefore, the most important feature of 4D technology is to give physical stimulus to the viewer.

In recent years, visitors have been able to experience visual, auditory, and olfactory close to actual situations when watching movies, and tactile effects using hot air are being developed.

However, the conventional technique using hot air is a method of discharging hot air from the front seat back cushion side to the back seat side. In order to obtain a high hot wind effect, a high heating power is required for a heat generating body that generates heat, and a blower that generates a wind is also high A power amount is required. Also, since the fan speed of fan accelerates as the power consumption of the blower increases, noise is generated by the fan. Therefore, there is a problem that a too loud noise for the viewer to feel the hot wind hinders the appreciation of the movie.

Therefore, when the hot wind function is used, the cost of the power consumption due to the hot wind effect is larger than the screening revenue of the movie theater. Therefore, in the movie theater, the 4D effect using the hot wind is not available.

In addition, since the front and back seats are not standardized in all movie theaters, they are applied differently in different countries and movie theaters. Therefore, in order to provide a proper hot air effect to the seated seats in the rear seat, heaters and blowers It is troublesome to control and control. In recent years, the space between the front and back seats has been widening for the convenience of the audience. As a result, it is expected that the cost of electric power usage due to the hot air effect will be further increased. In the case where the front seat and the rear seat are very wide, .

On the other hand, from the standpoint of stability, in the related art, a temperature sensor (bimetal) is mounted around the hot air module, and when the temperature exceeds a predetermined temperature, the temperature sensor operates to cut off power. At this time, if a failure occurs in the temperature sensor, it is impossible to control the temperature of the heating element, and there is a great risk of fire occurrence.

Therefore, although the hot wind effect is an essential constitution for feeling various 4D effects, the above-described limitations are encountered in reaching the commercialization stage.

Korean Registered Patent No. 10-1101278 (issued January 4, 2012)

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to reduce the amount of electric power required to generate hot air, thereby reducing the cost for installation and use in a movie theater.

Also, it is intended to provide a sufficient hot air effect even if the speed of the fan is lowered, thereby reducing the rotational noises of the fan, which interferes with the appreciation of the movie, and provide the comfort due to the appropriate hot wind intensity for the viewer to feel the hot wind.

In addition, the present invention provides a chair for mounting the effects of other visual, auditory, olfactory, vibration, etc. on a chair by downsizing and simplifying a module generating a hot air effect, lowering the cost of manufacturing, maintaining and repairing a 4D effect chair Thereby further securing an inner space.

It is another object of the present invention to more effectively prevent a fire hazard by using a resistance change characteristic of a material itself generating heat without installing and controlling a temperature sensor.

In order to achieve the above-mentioned object, a special effect chair of the present invention comprises a chair, a heating element provided inside the chair, a fan-shaped portion for flowing air heated by the heating element, And the discharging portion may be located on the front surface of the chair and may include air vent blades for controlling the direction or amount of air to be discharged.

Further, the special effect chair of the present invention can be formed of a material in which the resistance value of the heating target increases sharply at a specific temperature or higher, and the heating target includes the PTC heater. Further, it may further comprise a switch for controlling the driving of the heating element or the rich portion.

Further, the special effect chair of the present invention may further include a heat storage portion for storing heat heated by the heat generating body, and the heat storage portion may be coupled to the surface of the heat generating body, or may surround the heat generating body.

Further, the special effect chair of the present invention includes a seat portion, a receiving portion for supporting a lower portion of the seat portion, and a back portion formed upwardly by engaging with the seat portion or the receiving portion, can do.

Here, the discharging portion may be located at the upper end of the backrest front portion, and the heating element may be disposed between the discharging portion forming position in the back portion of the backrest inside the backrest.

Further, the special effect chair of the present invention may further include an armrest which is coupled to at least one side of the seat portion or the backrest, and the discharge portion may be located on the armrest.

The special effect system of the present invention is characterized in that a special effect chair including a heating element installed in a chair and a blowing portion for flowing air heated by the heating body and a discharging portion for discharging the air flowed by the blowing portion to the outside, And a control server for controlling at least one of a heating element and a blowing element of the chair.

Compared with conventional 4D chairs using a hot air effect, the present invention reduces power consumption required to generate hot air by reducing the spreading distance, miniaturization of the hot air generating module, and heat storage plate by 1/20 times from 2000W to 100W per 4T chair unit And thus the cost of installation and use in a movie theater can be drastically reduced.

In addition, by miniaturizing the jet range and the hot air generating module, it is possible to naturally reduce noise and electric power of the fan, and provide an effect that the visitor is sprayed with an appropriate wind speed to feel the hot wind and provides comfort.

On the other hand, the heating element of the present invention uses a material whose resistance value increases sharply at a specific temperature or more, so that it is not necessary to additionally provide a temperature sensor as in the prior art, There is a risk of fire due to failure or failure, but the present invention is more suitable for preventing fire due to high temperature control stability without using a temperature sensor.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may obscure the subject matter of the present invention.

FIG. 1 is a view showing the interior of a special effect chair 100 according to an embodiment of the present invention. FIG. 2 is a perspective view illustrating a coupling body according to an embodiment of the present invention (hereinafter referred to as a heating body 120, a blowing part 130, 140) and the heat storage portion 150 are referred to as a combination body)

The special effect chair 100 according to an embodiment of the present invention includes a chair 110, a heating body 120, a blowing unit 130, and a discharging unit 140. A heating unit 120 installed in the chair 110; a fan 130 for flowing air heated by the heating unit 120; and a fan 130 for controlling the fan 130, And a discharging unit 140 for discharging the air that has been flown by the chair 110 to the outside of the chair 110. The discharging unit 140 is located on the front of the chair 110. [

The heating element 120 is installed inside the chair 110 to generate heat to heat the surrounding air. For example, it is possible to convert electric energy into thermal energy, such as a method in which heat is generated by an electric resistor in an electric heating device such as an electric iron or an electric plate. However, the present invention is not limited thereto, and any method can be applied as long as electric energy can be used to generate heat.

The airflow 130 flows the air heated by the heating element 120. The fan-blowing unit 130 is coupled to the motor FAN to generate wind by rotating the FAN by the motor. This wind passes through the heat generating element 120 or the heat storage part 150, and hot air is generated. At this time, hot air and air blowing can be selectively discharged according to whether the heating element 120 is turned on or off.

For example, when an explosion scene appears, the heating element 120 may be turned on in advance to heat the air, and then the blowing fan 130 may be operated to discharge the hot air. In a scene where the air conditioner 120 is rapidly driven on a motorcycle, It is possible to operate the blowing unit 130 to produce a cool wind. This can be controlled by the control server 200, which will be described later.

At this time, a cooling module may be installed in place of the heating element 120 to discharge cold air. For example, a method of cooling the ambient air using a Peltier element can be used. In addition, the cooling module may be installed together with the heating element 120, and each of the cooling modules may be separately controlled by a control server to be described later. However, the present invention is not limited thereto, and any method can be applied as long as it can generate cold air.

The discharge unit 140 refers to an outlet through which heated air is discharged from the inside of the chair 110. The discharging part 140 is positioned on the front of the backrest 113. In this case, the viewer can feel the hot air discharged from the front part of the chair 110 backward.

In the conventional art, the discharging part 140 is located on the rear surface of the chair 110, so that the viewer can feel the hot air discharged from the front chair 110. As shown in FIG. 7, assuming that the discharge distance of the hot air is 1M from the discharge port to the viewer as in the conventional technique (see FIG. 7), when the discharge temperature is 128 degrees, Very high power consumption (2000W per unit) is required in order for the viewer to feel the hot wind effect due to the large temperature drop. However, since the discharging unit 140 is located on the front of the chair 110, the jetting distance is very close to the body of the visitor, so that a hot wind effect can be obtained with a low calorific power (100 W per unit) and a weak wind intensity, Is reduced by 1/20 times.

Therefore, since the discharging unit 140 can provide a sufficient effect even at a lower heating value than the prior art in which the discharging unit 140 is located at the rear side, components with low power consumption can be used and cost of other members such as connecting piping is reduced, The cost of use is much less, and noise caused by the rotation of the fan can be reduced since strong blowing is not required. Further, since it is not necessary to inject hot air farther, the smaller heating element 120 and the fan can be used, and the size of the combined body can be reduced. Therefore, the space inside the chair 110 for mounting other 4D technologies can be efficiently used Do.

The comparison data of the electric power amount difference and the production unit price according to the prior art and the present invention according to the position of the discharge part 140 are as follows.

In another embodiment of the present invention, the heating element 120 may use a material whose resistance value rapidly increases at a specific temperature or higher. An example of such a material is a PTC (Positive Temperature Coefficient) heater, which is made conductive by adding a trace amount of a rare earth element to the barium titanate, substitutes a part of Ba with Sr or Pb, Type semiconductor which can move and is defined as an element having a property of rapidly increasing the resistance value due to phase transition when a certain temperature is reached.

Since the PTC element can maintain a constant temperature at a desired temperature according to the length and area, when the heating element 120 is installed on the backrest 113, the PTC element can be manufactured to have an area and a length to maintain the surface temperature at about 170 degrees . However, the present invention is not limited thereto, and the PTC device may be manufactured by differentiating the area and length of the PTC device for maintaining the predetermined temperature depending on the installation position of the heating element 120. In addition, if the material can maintain a specific temperature by a similar principle, it can be applied to the heating element 120 as well.

The conventional method uses a material having a constant resistance regardless of the change in temperature, and there is a risk of fire when the temperature continuously increases. Therefore, when a temperature sensor is attached to the heating body 120 and the temperature of the heating body 120 And a method of controlling by turning off the power was used. As a result, it is necessary to additionally attach a temperature sensor, which is expensive to manufacture, and there is a risk of fire due to overheat when the temperature sensor fails.

On the other hand, according to the present invention, as the resistance value abruptly increases above a certain temperature, the increased resistance value limits the current so that the temperature is substantially constant despite variations in external temperature or power supply voltage. Accordingly, the present invention can control the temperature of the material itself without any additional temperature sensor, thereby reducing the installation cost by simplifying the structure compared to the prior art, and solving the fire risk due to the failure of the temperature sensor.

In one embodiment of the present invention, the chair 110 includes a seat portion 111, a receiving portion 112, and a back portion 113.

The seat portion 111 is a portion where the hip portion of the viewer comes into contact with the viewer when the seat is seated, and the receiving portion 112 supports the lower portion of the seat portion 111. The backrest 113 is coupled with the seat portion 111 or the receiving portion 112 and extends upward to support the viewer's back and head portion. The armrest 114 may be coupled to at least one side of the seat 111 or the backrest 113 to allow the viewer to hold his / her arm when watching a movie, or to place drinks, popcorn, and the like.

4), and when the discharge portion 140 is positioned at the front of the backrest 113, the spraying distance of the discharging portion 140 is adjusted to the body of the visitor It is possible to obtain an efficient hot wind effect even with a low calorific value and a weak wind strength. Therefore, since the discharging unit 140 can achieve a sufficient effect even at a lower calorific value than the prior art in which the discharging unit 140 is located at the rear side, the cost burden is reduced, and no noise due to rotation of the fan can be reduced. In addition, since it is not necessary to jet away the hot air, the smaller heating element 120 and the fan can be used, which makes it possible to miniaturize the overall hot air effect function configuration. Therefore, the space inside the chair 110 for mounting other 4D technologies can be efficiently .

Particularly, the discharge portion 140 is located at the upper end of the front portion of the backrest 113, and the heating body 120 is formed at the upper portion and the discharge portion 140 in the back of the backrest 113, It is possible to reduce the spreading distance of the hot air and make the discharge part 140 and the heat emitting body 120 as close as possible to further miniaturize the hot air effect function configuration.

3) further includes an armrest 114 coupled to at least one side of the seat portion 111 or the backrest 113, and the discharge portion 140 is connected to at least one side of the seat portion 111 or the backrest 113. In addition, May be positioned on the armrest 114. [ As a result, a hot air effect can be imparted to the viewer from the armrest 114 side (refer to FIG. 5), and by providing a plurality of assemblies in other portions, the viewer can feel a larger hot wind effect.

The position, size, and shape of the discharge portion 140 may be applied to various embodiments, and may be provided in both the backrest 113 and the armrest 114 (see FIG. 6).

In another embodiment of the present invention, the discharge portion 140 may include an air vent blade for controlling the direction or amount of air to be discharged. For example, the air vent blades can be coupled to both ends of the hole of the discharge portion 140 so that the blades can be vertically or horizontally adjusted, and the blades can be interlocked with each other to prevent air from being discharged. However, it is not limited to this, and any method can be applied if the direction and amount of wind can be controlled. In this way, visitors can adjust the amount of wind using air vent blades if they do not want hot wind effect.

In another embodiment of the present invention, the heat storage unit 120 may further include a heat storage unit 150 for storing heat. The heat accumulating part 150 is for storing heat heated by the heat generating element 120. The heat accumulating part 150 may be formed of a metal material capable of absorbing heat easily, It is possible to effectively store heat by forming a structure capable of storing air between metal and metal. At this time, aluminum or the like can be used as a material for easily storing and releasing heat.

The heat storage unit 150 is used to heat the heat generated in the heating element 120 inside the chair 110 by the heat storage unit 150 coupled to the heating element 120, When the enriched part 130 is operated, the heated air stored in the heat accumulating part 150 flows toward the discharging part 140. When the hot air is discharged to the discharging part 140 located on the front of the chair 110, It is possible to constitute an embodiment of a structure for sensing the effect. When the heat storage unit 150 is used as described above, there is an advantage that the amount of electric power can be saved by storing the heat by heating the air in advance.

Particularly, the heat storage unit 150 may be directly coupled to the surface of the heat emitting body 120, or may have a structure in which the efficiency is enhanced by keeping the heat transfer within a good range of the thermal conduction without contacting the heat storage body 120, (150) may surround the heating element (120) in the form of a circle or a sphere. When the heat emitting body 120 is surrounded by the spherical shape, the distance from the heat emitting body 120 to the heat storage portion 150 in any direction of the x, y, and z axes is the same.

And may include a switch 160 for controlling driving of the heating element 120 or the wind-up unit 130 according to another embodiment of the present invention (see FIG. 3). The switch 160 may control the driving of the heating unit 120 or the blowing unit 130 to turn on or off the hot air effect. The switch 160 may be located anywhere in a convenient place for the operation of the visitor and may be connected to the heating element 120 and the blowing part 130 to cut off or connect the power. For example, when the temperature is high as in the summer, the visitor may want a cool wind rather than a hot wind. In this case, if the viewer himself turns off the heating element 120, only the blow- Because of this, you can get a cool wind instead of a hot wind. In addition, a guest who does not want the hot wind or the blowing function can shut off the hot wind and the blowing function by turning off all the blowing part 130, the heating body 120 and the blowing part 130. In addition, the switch 160 may control the direction of the wind or the amount of wind to be blown by controlling the air vent blades.

In addition, according to another embodiment of the present invention, it is possible to adopt a configuration in which the assembly is installed inside a case made of a metal material to conserve heat.

On the other hand, the special effect system includes the special effect chair 100 and the control server 200.

The special effect chair 100 includes a heating unit 120 installed in a chair 110 and a fan 130 for flowing air heated by the heating unit 120 and a fan And a discharging unit 140 for discharging air to the outside. The discharging unit 140 is located on the front surface of the chair 110. At this time, the special effect chair 100 may include a communication unit for receiving the control of the control server, and may be connected to the control server through a local or wired network.

The control server 200 controls at least one of the heating body 120 or the airflow portion 130 of the special effect chair 100. In the memory of the control server, all the operation settings are stored every time the special effect of the movie is required, when the heating body 120, the blowing unit 130 should be operated and turned off. Accordingly, after the start of the image, each configuration of the special effect chair 100 is controlled according to the preset control time, so that all the special effect chair 100 can be controlled at one time and manually controlled if necessary.

For example, when the explosion scene (50 minutes 00 seconds) comes out, the air is heated by operating the heating element 120 in advance (49 minutes 00 seconds), and then the airflow 130 is actuated (49 minutes 59 seconds) (29 minutes 59 seconds) without operating the heating element (120), the setting for releasing the cool wind is stored in advance in the case of setting the discharge mode and driving the motorcycle quickly (30 minutes and 00 seconds) So that all the special effect chairs 100 of the auditorium can be controlled at a time so as to realize the hot wind and the blowing effect during the synchronized time during the actual movie screening.

In addition, the special effects chair 100 of the special effect system can be applied to the configurations of the various embodiments described above.

Thus, those skilled in the art will appreciate that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the embodiments described above are to be considered in all respects only as illustrative and not restrictive. The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents are to be construed as being included within the scope of the present invention do.
