Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. However, this is merely an example and the present invention is not limited thereto.

In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The following terms are defined in consideration of the functions of the present invention, and may be changed according to the intention or custom of the user, the operator, and the like. Therefore, the definition should be based on the contents throughout this specification.

The technical idea of the present invention is determined by the claims, and the following embodiments are merely a means for effectively explaining the technical idea of the present invention to a person having ordinary skill in the art to which the present invention belongs.

For example, although a heating element of an embodiment to be described later is an example of a heating wire which is a linear heating element, it is possible to apply an area heating element. Further, a soundproofing device for preventing noise and vibration by the blowing fan is shown on the lower side of the fan of the blowing fan, but this position is only one embodiment, and various modifications can be made by those skilled in the art.

1 is a perspective view showing an armrest 2 according to an embodiment of the present invention.

The armrest (2) can house an arm of a human body part and also includes a storage space for storing the object. Generally, the armrest 2 is provided with a seat, and when installed in a vehicle, the armrest 2 can be installed on at least one of the left side or the right side of the driver or the passenger. When installed in a vehicle, it is capable of direct contact with the human body and functions to control the air conditioning environment inside the vehicle. Referring to FIG. 1, for the air conditioning environment, the armrest 2 may include a blowing fan (200 of FIG. 2) for forced forced convection inside the vehicle, and air A through hole 411 may be formed so that the through hole 411 can be discharged. The air discharged to the through holes 411 may be discharged to the outside of the armrest 2 via the heat generating element 300 capable of heat exchange with the air to raise the air temperature inside the vehicle.

In addition, the heating element 300 included in the armrest 2 can heat-exchange with the air to raise the temperature of the air through the convection, thereby raising the temperature of the air outside the armrest 2. Furthermore, since the heating element 300 is disposed on the upper side of the armrest 2, heat can be transmitted from the outer side of the upper side of the armrest 2 to the arm through conduction while the arm of the human body is being held. Of course, this example corresponds to the case where the human body comes into contact with the upper side of the armrest 2, and the heating body 300 is arranged at another position to perform heat transfer by contact with the other side of the armrest 2 It is possible.

The control unit 33 may further include a control unit 33 for controlling the temperature and the discharge speed of the air discharged to the outside of the armrest 2 from the user. The operation unit 33 may include, for example, a temperature control button capable of determining the temperature of the air discharged by the user and a wind speed control button capable of determining the air discharge amount. Further, when the temperature control button is operated, the temperature of the heating element 300 may be raised. If the temperature of the heating element 300 rises above the temperature determined by the user during the temperature rise or overheats exceeding the predetermined temperature, It is possible to control such that the condition for overheating such as the power supplied to the heating element 300 is cut off by the overheat preventing means is not satisfied.

In addition, the armrest 2 may further include a display unit 500. Although the display unit 500 is formed with the operation unit 33 in FIG. 1, the display unit 500 and the operation unit 33 can be independently positioned at different points in a different configuration. In addition, the display unit 500 can display a temperature according to the air flow rate according to the rotational speed of the blowing fan 200 and the degree of heat generation of the heating element 300 with audible or visual information. For example, in the case of a display, it may be a means for displaying the information as time information.

Fig. 2 is a perspective view in side section showing the internal structure of the armrest 2 according to the embodiment of the present invention.

As described above, the heating member 300 described with reference to FIG. 1 can control the temperature inside the vehicle by convection by applying heat to the air exhausted from the blowing fan 200. However, And may be coupled with the case 100 so as to be adjacent to a portion where the arm comes in contact with the case 100 to transmit the heat. Therefore, the air conditioning environment can be comfortably provided through the convection using the heated air for the air conditioning environment inside the vehicle. In this method, there is a method of providing the armrest 2 further including a heater portion inside the case 100. [

Referring to FIG. 2, a heater unit may be positioned inside the case 100. In this case, the armrest 2 may include a case 100, a blowing fan 200, and a heater. Here, the heater unit may be an infrared heater 20, and in this case, it may further include a heat reflecting member 21. Hereinafter, the heater unit will be described below with an infrared heater 20 as an example. The heat reflecting member 21 may be positioned around the heater portion, for example, positioned adjacent to the inner surface of the case 100, and may be fixed to the inner space of the heat reflecting member 21 formed by the positioning, Or may be included in the armrest 2 by a method such as placement.

The case 100 may be divided into an upper case 110 and a lower case 120. The term " division " is meant to encompass both the case where the member can be physically detachable and the case where the region is functionally divided through the method of injection or the like. The upper case 110 includes a first discharge hole 111 through which air can be discharged to the outside of the armrest 2. The first discharge hole 111 is formed so as to be discharged to the outside of the armrest 2 via the flow paths 121 and 122 formed in the case 100. For example, Lt; / RTI >

In addition, the lower case 120 can receive air outside the inside of the armrest 2, and includes an inflow channel 121 through which the inflowed air flows and a discharge channel 122 through which the inflowed air is discharged . This air flow can be caused by the operation of the blowing fan 200. That is, the blowing fan 200 can be positioned on the path through which the air flows, and the front side of the blowing fan 200 is connected to the inflow channels 121, And the rear side may be the discharge passage 122. [ The discharge passage 122 may include a space until the air passes through the first through-hole 111 so as to be discharged to the outside of the armrest 2. The shapes of the flow paths 121 and 122 may be variously modified. However, in one embodiment, the flow paths 121 and 122 will be described later with reference to FIG. 3 (b).

Further, the infrared heater 20 may be located in the discharge passage 122. According to this structure, when the infrared heater 20 is positioned in the inflow channel 11, the distance from the air to the air after being heated is extended, so that the air can be cooled while moving. Can be reduced. As the structure for such thermal efficiency, the armrest 2 may further include a heat reflecting member 21. The heat reflecting member 21 can reuse the heat radiated from the infrared ray heater 20, particularly, the heat radiated toward the air flowing direction by reflecting the radiant heat.

Here, the space through which the air is heated from the heat reflecting member 21 may have a shape in which the front and rear sides of the flow path communicate with each other. That is, as shown in FIG. 2, the first through-hole 111 side and the blowing fan 200 side are communicated with each other to allow air to pass therethrough. When the infrared heater 20 is formed into a coil shape as shown in FIG. 2, a considerable amount of air can pass through the inside of the coil. In the process of passing through the inside of the coil, the air can be heated by the infrared heater 20 have.

Further, the heat radiated to the outside of the coil other than the heat radiated to the inside of the coil by the heat of the infrared heater 20 can be reflected to the space for heating the air. And the radiation heat radiated to the outside can be reused. The inside of the case 100 may continue to flow without stagnation of air due to the operation of the blowing fan 200, so heating by convection may be difficult. Therefore, the radiant heat radiated to the outside rather than the inside of the coil can be reintroduced into the space for heating the air.

FIG. 3 is a side view of the armrest 2 according to another embodiment of the present invention, and FIG. 3 (b) is a side view of the armrest 2 according to another embodiment of the present invention. Sectional side view of the armrest 2 according to another embodiment of the present invention.

Referring to FIG. 3, the infrared heaters 20a may be formed in a shape different from that of the infrared heaters 20 illustrated in FIG. Therefore, in the following, mainly the same contents as those of the armrest 2 of FIG. 2 will be omitted in the following description of the different shapes.

The infrared heaters 20a may be formed in a board form. The infrared heaters 20a may be arranged on the surface adjacent to the heat reflecting member 21 side. For example, it may be arranged so as not to interfere with the flow of air in the discharge passage 122 as shown in Fig. In the case of FIG. 3, the infrared heaters 20a are disposed on opposite sides of the heat reflecting member 21, but the arrangement may not be arranged in the opposite direction. The arrangement of the infrared heaters 20a may be arranged by a person skilled in the art in consideration of the information relating to the air flow, that is, considering the pressure drop and the heat exchange efficiency, and may be varied by the wall structure depending on the shape of the flow paths 121, have.

In the case of Fig. 3, the left and right inner surfaces of the heat reflecting member 21 can be covered by the infrared heater 20a on the discharge passage 122. [ Therefore, in this case, the portion of the heat reflecting member that can apply heat to the air by the heat reflecting effect can be the upper and lower sides. Since the heat is radiated from the outer circumferential surface when the infrared heater 20a is formed in a circular cross section, the radiant heat not radiated to the places where the infrared heaters 20a face each other is emitted in one direction, It can be re-supplied.

4 (a) is a side sectional view of the armrest 2 according to another embodiment of the present invention, and Fig. 4 (b) is a side view of the armrest 2 according to another embodiment of the present invention. b) is a front cross-sectional view of the armrest 2 according to another embodiment of the present invention.

Referring to FIG. 4, the infrared heater 20b and the heat reflecting member 21b may be formed in a shape different from that of the infrared heaters 20 and 20a and the heat reflecting member 21 illustrated in FIGS. Therefore, in the following, the same contents as those of the armrest 2 of FIGS. 2 and 3 will be omitted in the following description.

The infrared ray heater 20b may be formed in a bar shape. The infrared ray heater 20b may be arranged on the heat reflecting member 21b at a predetermined distance from the heat reflecting member 21b side. For example, it may be arranged so as not to interfere with the flow of air in the discharge passage 122 as shown in Fig. 3, the infrared heaters 20a are disposed on both opposite sides of the heat reflecting member 21. In the example shown in Fig. 4, the heat reflecting member 21b is arranged to be concave upward, bar type infrared heater 20b may be positioned above the heat reflecting member 21b at a predetermined interval from the heat reflecting member 21b. When the heat reflecting member 21b is disposed so as to face upward, the heat reflecting member 21b may be positioned obliquely in the case 100 as shown in FIG. The radiant heat reflected by the concave shape of the arrangement and heat reflection member 21b can be collected at the upper center. Since the radiant heat reflected from the infrared ray heater 20b is radiated downward from the infrared ray heater 20b, the radiant heat reflected by the concave heat reflecting member 21b is collected at the center to heat air passing through the heat reflecting member 21b.

On the other hand, when the heat reflecting member 21b is formed in a flat shape without being concaved, the radiant heat used for heating the air can be reduced because the reflected radiant heat is directed to the inner side surface of the case. Therefore, the heat reflecting member 21b can be formed concave to increase the amount of radiant heat used to heat the air. In addition, the heat reflecting member 21b in Fig. 4 may be a function of reflecting heat and a part of the discharge flow path 122. Fig. Therefore, the heat reflecting member 21b and the infrared heater 20b, which function as a flow path, can be arranged in parallel or parallel to each other. By this arrangement, the air flow can be prevented from being disturbed. That is, the arrangement structure of the heat reflecting member 21b and the infrared heater 20b can be changed by a person skilled in the art in consideration of the pressure drop and the heat exchange efficiency

The embodiments described with reference to Figs. 2 to 4 include the heat reflecting members 21 and 21b. Each of the heat reflection members 21 and 21b may be formed or plated with a predetermined material to increase heat reflection efficiency. For example, the heat reflecting members 21 and 21b may be plated or formed of one of silver, chromium, aluminum, and nickel.

Furthermore, the infrared heaters 20, 20a, and 20b included in the embodiments described with reference to Figs. 2 to 4 may be damaged in the interior of the case 100 due to vibration of the vehicle or impact applied to the armrest 2 from the outside A cover member 40 formed of a metal material or the like may be further included. The cover member 40 can be positioned between the heat reflecting members 21 and 21b and the case 100 to mitigate vibrations and shocks applied to the infrared heaters 20,20a and 20b and the heat reflecting members 21 and 21b have.

The armrest 2 can check the heating temperature of the infrared heaters 20, 20a and 20b through the display unit 500. When the infrared heaters 20, 20a and 20b are heated to a predetermined temperature or more, (20, 20a, 20b).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, . Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be determined by equivalents to the appended claims, as well as the appended claims.
