Field of Invention
The present invention relates generally to a cup holder for a vehicle and, more particularly, to a cup holder which is capable of enabling the temperature of the cup holder to be determined from the outside, fundamentally preventing accidents and injuries attributable to a user's carelessness, such as a burn injury, and effectively managing energy that is used to cool or heat the cup holder.
Description of Related Art
Generally, a thermoelectric element is used to selectively cool or heat a cup holder, and thus the cup holder can be installed in a compact space in a vehicle.
However, the cup holder using the thermoelectric element is problematic in that it is difficult to identify whether the cup holder is currently being cooled or heated. In addition, it has the risk of causing accidents and injuries attributable to a user's carelessness, such as a burn injury.
Therefore, in order to overcome the above problems, there is a need to enable the status of the cup holder to be determined using the color of light and also prevent accidents, such as a burn injury. In addition, there is a need to implement the cup holder in a unique design that can enhance its aesthetic value.
The information disclosed in this Background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art and/or other problems, and the present invention is directed to provide a cup holder which is capable of enabling the temperature of the cup holder to be determined from the outside, fundamentally preventing accidents and injuries attributable to a user's carelessness, such as a burn injury, and effectively managing energy that is used to cool or heat the cup holder.
In accordance with various aspects of the present invention, there is provided a cup holder for a vehicle, including: a holder body configured to accommodate a cup, provided with a thermoelectric element that cools or heats the cup, formed in a double sidewall structure, and provided with an internal blower that is disposed in the inner space of the double sidewall structure and circulates air around the cup; a support unit configured such that the front portion thereof protrudes from the inner side of the holder body and supports a side of the cup accommodated in the holder body, and provided with an illuminant that is capable of expressing a plurality of colors and radiates light onto the cup; a temperature sensor provided on the holder body, and configured to measure temperature; and a control unit configured to change a color of the illuminant of the support unit based on the measured temperature.
The holder body may include an inside holder body configured to accommodate the cup and to come into contact with the thermoelectric element, and an outside holder body configured to surround the inside holder body, wherein the internal blower is disposed in between the inside holder body and the outside holder body.
The internal blower may draw air between the inside holder body and the outside holder body, and may discharge the air toward the accommodated cup via a vent hole formed through the inside holder body. The support unit may be made of transparent material and provided with the illuminant including blue and red illuminants, and the control unit may separately control the light intensity of each of the blue and red illuminants.
When a cooling operation is performed, the control unit may operate the internal blower and an external blower, and may change a color of the illuminant of the support unit based on the measured temperature. When the cooling operation is terminated, the control unit may immediately stop the internal blower, and may keep the external blower operated for a predetermined time.
When a heating operation is performed, the control unit may not operate the internal blower or an external blower, and may change a color of the illuminant of the support unit based on the measured temperature.
When a cooling or heating operation is performed, the control unit may maximize a control duty of the thermoelectric element if the measured temperature has not reached a target temperature, and may reduce the control duty of the thermoelectric element if the measured temperature has reached the target temperature.
An opening may be formed through a side of an inside holder body, and a front portion of the support unit may protrude from the inner side of the inside holder body through the opening. The support unit may be provided with the illuminant including blue and red illuminants, and the control unit may separately control the light intensity of each of the illuminants. The control unit may control the support unit so that the support unit radiates darker red light in proportion to hotness of an inside holder body and radiates darker blue light in proportion to coldness of an inside holder body.
The cup holder may further include a switch configured to receive a request to cool or heat the accommodated cup. The control unit may operate the thermoelectric element and the illuminant of the support unit only when receiving the request through the switch.
The methods and apparatuses of the present invention have other features and advantages which will be apparent from or are set forth in more detail in the accompanying drawings, which are incorporated herein, and the following Detailed Description, which together serve to explain certain principles of the present invention.
Reference will now be made in detail to various embodiments of the present invention(s), examples of which are illustrated in the accompanying drawings and described below. While the invention(s) will be described in conjunction with exemplary embodiments, it will be understood that present description is not intended to limit the invention(s) to those exemplary embodiments. On the contrary, the invention(s) is/are intended to cover not only the exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the invention as defined by the appended claims.
The cup holder for a vehicle according to various embodiments of the present invention may include a holder body H configured to accommodate a cup, provided with a thermoelectric element 300 that cools or heats the cup, formed in a double sidewall structure, and provided with an internal blower 160 that is disposed in the inner space of the double sidewall structure and circulates air surrounding the cup; a support unit 600 configured such that a front portion thereof protrudes from an inner side of the holder body H and supports a side of the cup accommodated in the holder body H, and provided with illuminant 640 that is capable of expressing a plurality of colors and radiates light onto the cup; a temperature sensor 120 provided on the holder body H, and configured to measure temperature; and a control unit 1000 configured to change the color of the illuminant 640 of the support unit 600 based on a temperature value measured by the temperature sensor 120.
The cup holder according to various embodiments of the present invention selectively cools and heats the accommodated cup. For this purpose, the cup holder includes the thermoelectric element 300. As an example, such as an embodiment illustrated in
Radiation fins 400 and an external blower 500 configured to radiate heat may be provided on another side of the thermoelectric element 300.
The cup is accommodated in the inside holder body 100 and the inside holder body 100 is provided with the thermoelectric element 300, thereby selectively cooling or heating the accommodated cup.
In addition, the support unit 600 is configured such that the front portion thereof protrudes from the inner side of the inside holder body 100 and a rear portion thereof is configured to be elastic, thereby supporting a side of the cup when the cup is accommodated therein. In particular, the support unit 600 is provided with the illuminant 640 capable of expressing a plurality of colors, and thus radiating light onto the cup.

Meanwhile, the temperature sensor 120 is provided on the inside holder body 100 to measure temperature, and the control unit 1000 changes the color of the illuminant 640 of the support unit 600 based on a temperature value measured by the temperature sensor 120.
More specifically, an opening is formed through a side of the inside holder body 100, and the support unit 600 protrudes from the inner side of the inside holder body 100 through the opening. Accordingly, the support unit 600 radiates light onto a side of the cup while supporting the cup, thereby allowing the light to naturally and delicately spread across the space between the accommodated cup and the inside holder body 100. This provides the user with an aesthetic value, and at the same time, prevents the user from being dazzled.
In addition, the control unit 1000 may control the support unit 600 so that the support unit 600 radiates darker red light in proportion to hotness of the inside holder body 100 and so that the support unit 600 radiates darker blue light in proportion to coldness of the inside holder body 100. This enables the user to intuitively be aware of the temperature status of the cup. In particular, when the cup is hot, the user may be more wary of a burn injury.
Meanwhile, the cup holder according to the present invention may further include a switch 800 configured to receive a request to cool or heat the accommodated cup. In addition, the control unit 1000 may operate the thermoelectric element 300 and the illuminant of the support unit 600 only when receiving the request through the switch 800.
According to various embodiments of the present invention, the holder body H includes the inside holder body 100 configured to accommodate a cup and to come into contact with the thermoelectric element 300, and the outside holder body 900 configured to surround the inside holder body 100 and to have the internal blower 160 between the inside holder body 100 and itself. In addition, the internal blower 160 draws air between the inside holder body 100 and the outside holder body 900, and discharges the air toward the accommodated cup via the vent hole 162 formed through the inside holder body 100.
Meanwhile, the support unit 600 is made of transparent material and provided with the illuminant 640 including a plurality of illuminants such as blue and red illuminants, and the control unit 100 separately controls the light intensity of each of the illuminants.
In particular, as described in
Meanwhile, as described in
In addition, when a cooling or heating operation is performed, the control unit 1000 maximizes the control duty of the thermoelectric element if a temperature value measured by the temperature sensor has not reached a target temperature at steps S170, S180, S270 and S280, and reduces the control duty of the thermoelectric element if the temperature value measured by the temperature sensor has reached the target temperature at steps S190 and S290.
