Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drink holder provided inside a vehicle, such as an automobile, capable of holding a beverage container such as a can, a bottle, a paper cup, etc. The present invention relates to a drink holder capable of keeping heat and cold together with a container.

[0002]

2. Description of the Related Art For example, a drink holder for holding a beverage container such as a can, a bottle or a paper cup is mounted on a vehicle such as an automobile.

A drink holder used in an automobile or the like, for example, comprises a bottom frame on which a beverage container is placed and an upper support frame for supporting the upper portion of the beverage container, and is adjacent to the seat. It is provided detachably or foldably on the inner wall of the door, the instrument panel, the back of the seat back of the front row seats, and the like.

[0004]

By the way, cans, bottles,
Drinks such as juice and coffee sold in paper cups can be generally classified into hot drinks and cold drinks. In order to drink and store such drinks deliciously for a long time, it is desirable to keep the drinks warm and cold at a temperature close to that at the time of sale.

However, in the known drink holder, it is difficult to keep the drinks at an appropriate temperature because the drink holder itself does not have a heat retaining / cooling means.

In a known drink holder, for example, it is attached to an outlet of an air conditioner (air conditioner) and a beverage container is attached at a temperature of wind from the air conditioner.
In other words, it is known that drinks can be maintained at an appropriate temperature.

However, in the known drink holder constructed to be attached to the outlet of the air conditioner, the air from the air conditioner is merely applied directly to the beverage container such as a can, so that the drink can be effectively kept warm. , I can't expect to keep cool enough.

In the drink holder as described above, only heat retention during heating by the air conditioner and cold retention during cooling can be performed, so that heat retention or cold insulation cannot be selected depending on the user's preference.

Further, since such a drink holder is attached to the outlet of the air conditioner, the beverage container held by the drink holder interferes with the blowing of the air from the air conditioner, which lowers the efficiency of air conditioning in the interior of an automobile or the like. There is a risk of inviting.

The present invention provides a drink holder that allows the drinks to be properly kept warm and cold by providing them with a function of keeping warm and cool, and at the same time, preventing a decrease in the air conditioning efficiency of the interior of a vehicle or the like. Has an aim.

[0011]

In order to achieve this object, according to one embodiment of the present invention, a warming / cooling element that produces a Peltier effect under the supply of electric current is provided on the bottom surface of the beverage container. One of the pair of heat transfer surfaces is disposed so as to be contactable and exposed above the bottom surface of the bottom frame. Then, the current supply direction can be reversed in the forward and reverse directions,
The heat and cold insulation element is connected to the power supply and heat is generated and absorbed under the Peltier effect on the exposed surface of the heat and cold insulation element, which is selected by switching the current supply direction. Can be kept warm and cold.

[0012]

In this structure, since the drink holder itself has the heat retaining / cooling element for the beverage container, the heat retaining / cooling of the drink at an appropriate temperature can be easily obtained. Further, since it is not necessary to attach it to the air outlet of the air conditioner, it is possible to select whether to keep the drink warm or cold according to the user's preference, and also not to lower the air conditioning efficiency in the vehicle interior or the like.

[0013]

Embodiments of the present invention will now be described in detail with reference to the drawings.

As shown in FIG. 1, a drink holder 10 according to an embodiment of the present invention is arranged with a bottom frame 12 on which a beverage container is placed, and a beverage placed on the bottom frame. And an upper support frame 14 provided so as to be able to support the upper part of the container.

The bottom frame 12 and the upper support frame 14 are, for example, connected to a mounting base 16 via individual pivot pins 18 and 19 so as to be swingable in the vertical direction, and are used substantially horizontally as shown in FIG. It can be folded from the position to the flip-up position shown in FIG.

As shown in FIGS. 1 and 3, the bottom frame 12 usually has an upper edge 12b extending upward from the bottom surface 12a so as to prevent the bottom portion of the beverage container 20 to be placed from being displaced. Are integrally formed. Further, the upper support frame 14 is generally formed in a substantially circular shape as shown in FIG. 1 from a general shape of the beverage container 20, that is, a can, a bottle, a paper cup or the like.

In such a drink holder 10, as shown in FIG. 1, each end of the connecting arm 22 is pivoted to the bottom frame 12 and the upper support frame 14 behind the pivot pins 18 and 19, respectively. When they are worn, they are linked so that they can be interlocked, and they can be integrally folded under the flip-up motion of either the bottom frame or the upper support frame.

The drink holder 10 is attached to the inner wall of the door and the instrument panel adjacent to the seat, the back of the seat back of the seat in the front row, and the like via the mounting base 16.

Here, in the drink holder 10 of the present invention, the bottom frame 12 is provided with a heat retaining / cooling element 24 which produces a Peltier effect under the supply of electric current. The Peltier effect is a phenomenon in which, when two different types of semiconductors are brought into contact with each other and a current is passed through them, heat is generated or absorbed at the contact end. The heat-retaining / cooling element 24 is configured so that the beverage container can be kept warm and cold under cooling by absorbing heat.

As shown in FIG. 4, as the heat insulating / cooling element 24, for example, a P-type semiconductor 26 made of a bismuth-tellurium compound or the like and an N-type semiconductor 27 made of alumina, ceramic or the like are alternately arranged and joined. Non-conductor 30-1, 30-2
A PN junction semiconductor having a structure sandwiched by can be used. In such a configuration, the adjacent P-type semiconductor 26 and N-type semiconductor 27 are electrically connected to each other via the conductive metal 32 such as copper, and are arranged at each end. The semiconductor is connected to a power supply 34, which is a current supply source, using the same conductive metal as a terminal.

As the power source 34, for example, a battery of an automobile or the like can be used.

In such a heat retaining / cooling element 24,
The non-conductors 30-1 and 30-2 are configured to function as heat transfer surfaces that transfer heat from the joint ends to the outside. As shown in FIGS. 1 and 3, in this embodiment, for example, only the non-conductor 30-1 on the upper surface in the figure can be used as the heat transfer surface, and the surface is located above the bottom surface 12a of the bottom frame 12. It is exposed.

Here, since the bottom portion of the beverage container 20 such as a can or a paper cup is usually formed in a so-called raised bottom shape, the heat insulating / cooling element 24 can be seen from FIG.
The corresponding heat transfer surface (non-conductor) 30-1 is arranged so as to project to a height capable of contacting the bottom surface 20a of a can, a paper cup or the like.

As shown in FIG. 5, the heat retaining / cooling element 24 is
For example, it is connected to the battery (power supply) 34 via a main switch 38 which is a power switch. Then, the heat retention / cooling element 24 heats one heat transfer surface 30-1 and cools the other heat transfer surface 30-2 under the supply of a current in the forward direction, while the heat transfer element 30-2 in the opposite direction is heated. In contrast to this, under the supply of electric current, it has the property of cooling the heat transfer surface 30-1 and heating the heat transfer surface 30-2. It is possible to reverse the current supply direction of
The main switch 38 is connected and configured.

As the main switch 38, for example, an interlocking type three-contact changeover switch having two combinations of a main contact 38-a and three-point changeover contacts 38-O, 38-H, 38-C can be used, The switching contact 38-O is formed as an OFF contact, and the switching contacts 38-H and 38-C are formed as a warm contact and a cold contact, respectively.

The main switch 38 is provided at a position where the user can easily operate it, for example, on the front surface of the bottom frame 12 as shown in FIG. Here, the position of each contact of the main switch 38, that is, the OFF contact, the warm contact, and the cold contact may be displayed by OFF, HOT, COLD, etc. as shown in FIG. With such a configuration, since the positions of the respective contacts are clarified, erroneous operation and the like can be reliably prevented.

The main switch 38 is exemplified as an interlocking type three-contact switch, but it is sufficient if the power supply can be turned on and off and the current supply direction can be switched under the contact switching. The configuration is not limited to the illustrated configuration, and other switch means may be used as the main switch.

Then, the main switch 38
The present invention is not limited to the configuration of performing both N, OFF and switching of the current supply direction, and for example, the main switch may be divided into a power switch and a switching switch. However, as in the example, the main switch
If the power supply 38 can be turned on and off and the current supply direction can be switched, the number of parts can be reduced and the configuration can be simplified.

Further, reference numeral 40 in FIGS. 1 and 2 denotes a harness extended from the main contact 38-a of the main switch 38. By connecting the harness to the battery 34, the current from the battery is kept warm.・ Can be supplied to the cool element 24.

For example, in the initial state shown in FIG.
From the OFF state, operate the main switch 38 to
When 38-a is switched from OFF contact 38-O to heat retention contact 38-H,
The current from the battery 34 flows in the positive direction indicated by the solid arrow, and is supplied to the heat retention / cooling element 24 via the path. Then, the heat transfer surface 30-1 of the heat retaining / cooling element is heated under the supply current in the forward direction, so that the beverage container 20 placed on the heat retaining / cooling element 24 as shown in FIG. In other words, drinks are heated and kept warm from the bottom surface 20a.

When the main contact 38-a is switched to the cold insulation contact 38-C under the operation of the main switch 38, the battery 34
The electric current from flows in the opposite direction shown by the one-dot chain line arrow, and is supplied to the heat retention / cooling element 24 via the route. Then, the heat transfer surface 30-1 of the heat retaining / cooling element is cooled under the supply current in the opposite direction, which allows the beverage container to be cooled.
20, that is, drinks are cooled and kept cool.

As described above, according to the drink holder 10 having this structure, the drink holder itself is a heat retaining / cooling element.
Since the beverage container 20 is directly heated and cooled under the condition that the beverage container 20 is mounted on the device, the drinks can be kept warm and cold accurately.

Further, unlike the known structure provided at the outlet of an air conditioner (air conditioner), the drink holder 10 of the present invention is attached independently of the air conditioner, so that the air conditioning efficiency of the air conditioner does not decrease. Further, since it is possible to set a single temperature independently of the air conditioning temperature in the air conditioner by the heat retaining / cooling element 24, the user's favorite temperature setting can be performed without being influenced by the air conditioning temperature.

Further, a heat insulating / cooling element is provided on the bottom surface 12a of the bottom frame.
Since the provision of 24 is sufficient, the drink holder 10 that can maintain drinks at an appropriate temperature can be provided at low cost without complicating the configuration.

It should be noted that in the heat insulation / cold insulation element 24 used in this drink holder 10, it is usually 80 ° C to -20 ° C.
Since the temperature in the range of C can be obtained, the temperature at the time of heat retention and the temperature at the time of cold storage are set within this range, respectively.

As can be seen from FIGS. 2 and 3, in the present invention, the bottom frame 12 is the protective wall below the bottom surface.
Formed with 42. The protection wall 42 is integrally provided from a lower edge 12c extending downward from the bottom surface 12a, and is configured to protect the heat retention / cooling element 24 provided on the bottom surface from below.

In the drink holder 10 of the present invention, below the bottom surface 12a, that is, the heat retention / cooling element 24
Ventilation holes 44 and 45 that allow convection of air on the other heat transfer surface 30-2 are provided at a plurality of positions on the protective wall 42 and the lower edge 12c.
Each is provided. In such a configuration,
Convection of air on the side of the heat transfer surface 30-2 of the cold insulation element 24 allows accurate heat exchange on that surface, so sufficient heat and cold insulation effects are secured on the projected heat transfer surface 30-1. it can.

Further, in this structure, the protective wall 42 and the lower edge 12c are merely provided with the ventilation holes 44 and 45, respectively. In other words, the heat transfer surface 30-2 side of the heat insulation / cold insulation element is
Since the protection wall 42 and the remaining portion of the lower edge 12c are reliably protected, contact with the user's finger or the like can be sufficiently prevented. Therefore, the protection wall 42 ensures sufficient safety for users and the like.

The ventilation holes 44 and 45 having the shapes and sizes shown in the drawing are used.
The protective wall 42 is not limited to the configuration having, and, for example, a mesh plate provided with a large number of holes is also included in the protective wall 42 here.

Further, for example, the temperature of the heat retaining / cooling element 24 may be monitored by the temperature monitoring means 48. As the temperature monitoring means 48, for example, a positive temperature coefficient thermistor (PTC thermistor) that reduces the flow of current due to a sharp increase in resistance due to a temperature increase above a certain level can be used.

As shown in FIG. 5, the PTC thermistor (temperature monitoring means) 48 is provided, for example, when a current is supplied in the positive direction.
In other words, when detecting an excessive temperature rise during heat retention on the heat transfer surface 30-1 of the heat insulation / cold insulation element, the heat insulation contact 38-H of the main switch and the heat insulation contact 38-H of the main switch are arranged so as to decrease the current supplied from the battery 34. -Connected to the cold insulation element 24. Further, as shown in FIG. 3, the PTC thermistor 48 is arranged adjacent to the heat insulating / cooling element 24 on the side of the heat transfer surface 30-2.

In such a configuration, when the temperature of the PTC thermistor 48 rises under the application of a constant voltage and the temperature of the PTC thermistor reaches its characteristic temperature, the supply current decreases due to the increase of the resistance value. Since the current supplied to the heat insulation / cold insulation element 24 is limited, it is possible to reliably prevent an excessive temperature rise in the heat insulation / cold insulation element. Therefore, the safety during heat retention is further improved.

When the temperature detected by the PTC thermistor 48 falls below the characteristic temperature, the supply current is returned to the initial value due to the decrease in resistance value, so that the heat retention / cooling element 24 can keep warming repeatedly. Become.

Here, in the embodiment, the drink holder 10 is embodied as a structure in which the bottom frame 12 and the upper support frame 14 can be folded by flipping up, but the beverage container 20 is mounted on the bottom frame. Since a drink holder that can be placed is sufficient, the present invention can also be applied to a drink holder that has a bottom frame and an upper support frame fixed at a use position and has a non-foldable structure. However, if the bottom frame 12 and the upper support frame 14 can be folded by flipping up, the drink holder 10
Since it does not get in the way when not in use, the space around the drink holder can be effectively used when not in use.

By the way, in the above-mentioned embodiment, the drink holder 10 is embodied as a structure in which the warm / cold element 24 switches between warm and cold by switching the main switch 38. However, not limited to this,
For example, paying attention to the fact that when the heat transfer surface 30-1 of the heat retention / cooling element is heated, the other heat transfer surface 30-2 is cooled at the same time. The cold insulation element 24 may be configured to switch between heat retention and cold insulation.

As shown in FIG. 6, also in the drink holder 110 according to another embodiment of the present invention, the bottom frame 112 and the upper support frame 114 are attached to each other by the pivot pins 18 and 19.
It is connected to 16 so that it can flip up. The bottom frame 112 and the upper support frame 114 are connected to each other in an interlockable manner, for example, via the connecting arm 22 as in the above embodiment.

Here, as shown in FIGS. 6 and 7, the bottom frame 112 of this drink holder has a support shaft 52 arranged on the side.
The upper and lower surfaces of the link 50 are reversibly connected to each other via the link 50, and are connected to the mounting base 16 by the support of the link by the pivot pin 18.

As can be seen from FIG. 7, the heat retention / cooling element 24 has, for example, both the heat transfer surfaces 30-1 and 30-2 from the upper and lower surfaces of the bottom surface 12a of the bottom frame to the bottom surface 20a of the beverage container. It is arranged so as to project to a height at which it can contact.

In this structure, since the bottom container 112 is turned over, the warming / cooling element 24 switches the warming / cooling of the beverage container 20, that is, the drinks. Therefore, as shown in FIG. , OFF only switchable, for example,
A holding type push switch is interposed and connected as the main switch 54 between the heat retention / cooling element 24 and the battery 34 serving as a power source.

As shown in FIGS. 6 and 7, the main switch 54 is provided at a position where the user can easily operate it, for example, on the front surface of the mounting base 16.

Here, as the main switch 54, for example, a so-called pilot lamp-equipped structure having a pilot lamp 54b which is turned on by the ON operation of the contact 54a as shown in FIG. 8 may be used. If such a switch with a pilot lamp is used as the main switch 54, ON / OFF of the main switch, that is, power ON / O
Since the FF is clarified, erroneous operation can be reliably prevented, and the drink holder 110 with excellent operability and safety can be easily secured.

For example, assuming that the heat transfer surface 30-1 is a heat retaining surface and the heat transfer surface 30-2 is a cold retaining surface, in the state shown by the solid line in FIG. 9, the placed beverage container 20 is the main switch.
When the ON operation of 54 is performed, the heat is maintained under the heating of the heat transfer surface 30-1 of the heat insulating / cooling element. Then, for example, when the upper and lower surfaces of the bottom frame 112 are inverted by rotating in the counterclockwise direction around the support shaft 52 and passing through the state shown by the chain double-dashed line, the heat retaining / cooling element formed as a heat retaining surface is formed. Since the heat transfer surface 30-2 of the above is reversed from the illustrated state and is positioned above, the beverage container 20 placed on the side frame 112 can be kept cool.

In other words, in the drink holder 110 of the embodiment, the heat insulation / cold insulation element is operated by reversing the bottom frame 112.
Since the heat insulation and the cold insulation are switched by 24, the operability is improved without complicating the operation.

Then, the main switch 54, which is an ON / OFF switch, is provided with a warm / cold element 24 and a battery 34.
Since it is sufficient to simply intervene between and, the configuration is further simplified.

As shown in FIG. 6, for example, HOT,
It is preferable to clarify the heat retaining side and the cold retaining side of the bottom frame 112 by displaying COLD. In such a configuration,
Since erroneous setting of heat retention and cold retention can be reliably prevented, operability is improved from this point as well.

Further, as shown in FIG. 9, in the drink holder 110 of this embodiment, since both the upper and lower surfaces of the bottom frame 112 are open, the convection of air occurs in both cases of keeping warm and keeping cold. The heat exchange due to is smoothly performed.

In this drink holder 110, the bottom frame 112 is formed integrally with both the upper edge 112b and the lower edge 112c. With such a configuration, even when the beverage container 20 is placed on either side of the bottom frame 112, it is possible to prevent the lower part of the beverage container from being displaced, and to keep warmth and anticipation of fingers etc. to the cold insulation element 24. High safety is sufficiently ensured because it is possible to reliably prevent contact with the welding.

Here, for example, the flip-up detection means 56 monitors the flip-up of the bottom frame 112, and the flip-up of the bottom frame,
That is, when the folding is detected, the current supplied to the heat retention / cooling element 24 can be immediately cut off. As shown in FIG. 8, as the flip-up detection means 56, for example, an automatic reset type push switch interposed and connected between the battery 34 and the main switch 54 can be used.

As shown in FIGS. 6 and 7, the push switch (bounce-up detecting means) 56 is a member that can be interlocked with the swing of the bottom frame 112 in the vertical direction, for example, the pressing piece 50 of the link 50.
It is arranged at a position where the switch piece 56a can be pressed by a and is turned on when the switch piece 56a is pressed at the position where the bottom frame is used.

For example, from the use position shown in FIG.
When the 112 is flipped up, as shown in FIG.
By swinging the link 50 around the
Since a is separated from the switch piece 56a of the push switch, the push switch 56 is
Turns off. Then, as shown in FIG. 8, since the push switch 56 is interposed between the heat retention / cooling element 24 and the battery 34, the push switch OFF operation causes
The current supplied from the battery is ON / OFF of the main switch 54
It is cut off regardless of the heat retention by the heat retention / cooling element,
Cold insulation is interrupted.

According to this structure, since the heat insulation / cold insulation element 24 is turned off under the folding of the bottom frame 112, the operation of the heat insulation / cold insulation element after folding, that is, the excessive heating of the heat insulation surface is surely performed. Can be prevented. Therefore, also in this respect,
High safety can be sufficiently secured.

Here, in the embodiment, it is possible to detect the flip-up of the bottom frame 112 by pressing and releasing the switch piece 56a of the push switch by the press piece 50a of the link. Since it is sufficient if the switch piece can be pressed and released by a possible member, the switch piece is not limited to the link, and the switch piece may be pressed and released by a member other than the link or the bottom frame itself.

Further, in the embodiment, the push switch of the automatic return type is embodied as the flip-up detecting means 56, but it is sufficient if the flip-up of the bottom frame 112 can be detected. Other switch means such as a push-off switch may be used as the flip-up detection means.

By the way, in the embodiment, a PN junction semiconductor is used as the heat retaining / cooling element 24. However, it is an element capable of obtaining the Peltier effect of generating and absorbing heat under the supply of electric current. Since there is enough, the heat insulation / cold insulation element is PN
It is not limited to the junction semiconductor. However, if a PN junction semiconductor is used as the heat insulation / cold insulation element 24, it is possible to easily obtain heat insulation and cold insulation by supplying current, and switching between the heat insulation side and cold insulation side by reversing the supply direction, which complicates the configuration. It is possible to ensure adequate heat retention and cold storage without

A holding type push switch is used as the main switch 54, but it is sufficient if the power can be turned on and off. Therefore, other switch means such as a slide switch and a toggle switch can be used as a main switch. The switch 54 may be formed.

Although the drink holder of the present invention is suitable for automobiles such as passenger cars, it is not limited to this. For example, it can be used for drink holders provided on other automobiles such as buses, trains, airplanes, ships and the like. The present invention may be applied. Further, the idea of the present invention can be sufficiently applied to a drink holder provided on the back of a seat back of a seat in a movie theater, a theater, etc. without being limited to a vehicle or the like.

The above-mentioned embodiments are for explaining the present invention, and do not limit the present invention in any way.
It goes without saying that the present invention includes all those which are modified or modified within the technical scope of the present invention.

[0068]

As described above, according to the drink holder of the present invention, the drink holder itself has a heat retaining / cooling element, and the beverage container is directly heated and cooled by being placed on the element, Since the drinks are kept warm and cold, the drinks can be kept warm and cold accurately.

Since the air conditioner is installed independently of the air conditioner of an automobile, the air conditioning efficiency of the air conditioner does not decrease. Further, since it is possible to independently set the temperature by the warming / cooling element, the temperature setting desired by the user can be appropriately performed without being influenced by the air conditioning temperature.

Furthermore, since it is sufficient to provide a heat retaining / cooling element on the bottom surface of the bottom frame, a drink holder capable of maintaining drinks at an appropriate temperature can be provided at low cost without complicating the structure.

Further, if the lower surface of the heat insulation / cold insulation element is covered with the protective wall below the bottom surface of the bottom frame, unexpected contact by the user or the like can be reliably prevented, so that the safety is improved.

If the main switch is used to switch the power off and keep warm or cool, the structure can be simplified, and the operability is improved without complicating the operation.

Further, the temperature monitoring means monitors the temperature of the heat retaining / cooling element, and if the supply current to the heat retaining / cooling element is reduced by detecting an excessive temperature rise, the excess temperature of the heat retaining / cooling element is reduced. Since the rise can be reliably prevented, the safety during heat retention can be further ensured.

Further, in the structure in which the bottom frame is inverted to keep the heat and cold, the simplification of the structure and the simplification of the operation can be sufficiently ensured.

If a switch with a pilot lamp is used as the main switch, the switch is turned on and off.
Since the FF is clarified, erroneous operation can be surely prevented, and operability is sufficiently improved.
