Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating chair with a cool box, and can be used in a cooler box used for camping, fishing and the like.

[0002]

2. Description of the Related Art Conventionally, a foldable chair is used in camping, fishing, etc. so that it can be easily carried. However, in the winter, the sitting part of the chair was cold, and the wind was flowing under the sitting part to cool the buttocks, which caused discomfort.

On the other hand, as a conventional cool box, for example, a technique disclosed in Japanese Patent Laid-Open No. 3-221775 is known. This is because a heat-insulating box having an accommodation space for accommodating an article and an opening for taking in and out an article, a lid for closing the opening, and a heat transfer surface attached to the lid for absorbing heat to a thermoelectric conversion element are provided. A cool box having a heat absorbing member in contact, a heat radiating member in contact with the heat radiating surface of the thermoelectric conversion element in a heat transfer relationship, and a fan for generating an air flow around the heat radiating member, the heat radiating member being in contact with the outside air. Therefore, it wasted in vain in order to radiate heat.

[0004]

SUMMARY OF THE INVENTION It is a technical object of the present invention to provide a chair that is warm even in winter by making effective use of the heat generated by a cool box using a thermoelectric conversion element.

[0005]

In order to solve the above-mentioned technical problems, the technical means taken in the invention of claim 1 is provided with a storage space for storing articles and an opening for taking in and out the articles. A heat insulating box, a lid that closes the opening, a seat formed on the heat insulating box or an upper portion of the lid, and heat absorption that is located above the storage space and contacts the heat absorbing surface of the thermoelectric conversion element in a heat transfer relationship. That is, a member and a heat radiating member having one surface in contact with the heat radiating surface of the thermoelectric conversion element and the other surface in contact with the seat portion in a heat transfer relationship.

Preferably, the cooling device has a fan for cooling the heat radiating member, and the fan is provided with a delaying device which operates after a predetermined time elapses from energization of the thermoelectric conversion element.

More preferably, the heat absorbing member and the heat radiating member are built in the lid, the opening is provided above the storage space, and the seating portion is provided on the top of the lid.

[0008]

In the present invention, since the heat radiating surface of the thermoelectric conversion element is in contact with the seat portion in a heat transfer relationship via the heat radiating member, a warm chair can be provided even in winter. Further, the heat generated from the cool box using the thermoelectric conversion element can be effectively used.

Further, by having a fan for cooling the heat radiating member, and the fan being provided with a delaying means which operates after a predetermined time elapses from the energization of the thermoelectric conversion element, a short time can be obtained at the initial stage of energization of the thermoelectric conversion element. The seat can be warmed.

Further, since the heat absorbing member and the heat radiating member are built in the lid, the opening is provided above the storage space, and the seating portion is provided above the lid, heat is absorbed from above the storage space. It is highly efficient, and there is no risk of leaking from the opening even if a product with a large amount of water is stored in the storage space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described with reference to the drawings.

As shown in FIGS. 1 and 2, a heating chair 10 with a cool box is composed of a heat insulating box 11 and a lid body 12,
Both are detachable or openable / closable by an engaging member 11a. The heat insulation box 11 is composed of an outer skin 13 and a heat insulation wall 14 arranged inside the outer skin 13, and forms a storage space 15 that opens upward in FIG. 2. The lid 12 is
The opening of the storage space 15 can be closed, and the outer skin 16
A heat insulating wall 17 which is held by the outer skin 16 and closes the opening of the storage space 15, a Peltier element (thermoelectric conversion element) 18 fitted in the central hole 17a of the heat insulating wall 17, and a Peltier element 18
A heat-absorbing fin 19 fixed to the heat-absorbing surface 18a of the Peltier element 18 and a heat-conducting material (heat-dissipating member) 20 fixed to the heat-dissipating surface 18b of the Peltier element 18 and made of a material having good heat conductivity (for example, aluminum); It is composed of a urethane 21 which is held by the heat conductive material 20 and constitutes a seat portion.
The Peltier element 18 is connected to the control device 24,
The controller 24 turns on / off the power supply to the Peltier element 18 by the power switch 22, and turns on / off the fan 25 by the strength / weakness change switch 23 to change the heat radiation effect of the heat conductive material 20 in contact with the heat radiation surface. By changing the heat absorption effect of the heat absorption fins 19, the storage space 15
The degree of cooling inside can be changed. 16a in the figure
Is an air inlet of the fan 25, and 16b is an air outlet.

Reference numeral 24 in FIG. 2 denotes a control device, and FIG. 3 shows the processing performed by the control device 24. First, the power switch 2
When 2 is turned on, the control device 24 starts to operate, and the Peltier element 18 is energized in step S1. next,
When a predetermined time (for example, 2 minutes) has elapsed in the timer configuring the delay means in step S2, the process proceeds to step S3, and it is determined whether the strength / weakness change switch is strong or weak. If so, the process proceeds to step S4 to rotate the fan 25, and then the process returns to step S3. If weak, step S3 again
The process of is repeated.

In this embodiment, since the heat radiation surface 18b of the Peltier element 18 is in contact with the urethane 21 via the heat conductive material 20 in a heat transfer relationship, a warm chair can be provided even in winter.

Further, the heat generated from the cool box using the Peltier element 18 is effectively used.

Further, since the fan 25 is provided with a timer so as to operate after a predetermined time elapses from energization of the Peltier element 18, the urethane 21 is warmed in a short time at the initial stage of energization of the Peltier element 18.

Further, the lid 12 has the heat absorbing fins 19 built therein, and when the heat absorbing fins 19 are located above the housing space 15, the housing space 15 absorbs heat from above, which is efficient.

Further, since the storage space 15 is opened upward, there is no fear of leaking from the opening even when storing a water-rich article.

[0019]

According to the first aspect of the invention, since the heat radiation surface of the thermoelectric conversion element is in contact with the seating portion in a heat transfer relationship via the heat radiation member, a warm chair can be provided even in winter. Further, the heat generated from the cool box using the thermoelectric conversion element can be effectively used.

According to the second aspect of the present invention, the fan for cooling the heat radiating member is provided, and the fan is provided with the delay means that operates after a predetermined time elapses from the energization of the thermoelectric conversion element. The seat can be warmed in a short time in the initial stage.

According to the third aspect of the present invention, the heat absorbing member and the heat radiating member are built in the lid, the opening is provided above the storage space, and the seating portion is provided on the top of the lid, whereby the storage space Since heat is absorbed from above, efficiency is high, and there is no risk of leaking from the opening even if an article with a large amount of water is stored in the storage space.
