A bag that enhances pleasant functionality {A BAG}

[0001] The present invention relates to a bag which improves comfortability, and more particularly, to a bag which improves comfortability, and more particularly to a bag which comprises a casing, a delivery fan, a thermoelectric element, a heat radiating plate, a discharge fan, and a power supply unit on one side of the backrest, The present invention relates to a thermoelectric conversion device that selectively uses cold and hot depending on an external environment and separates the casing into a delivery chamber and an exhaust chamber to separate the effective heat and the waste heat section of the thermoelectric device to improve the thermoelectric efficiency of the thermoelectric device. To the bag.

BACKGROUND ART In general, bags used for climbing or for students' backpacks are mainly composed of a bag body for accommodating objects and a shoulder strap for shoulders.

However, when the bag having the structure described above is put on the back of the bag body containing the food or the book, the heavy bag body is closely adhered to the user's back, and when the heavy bag is put on the back for a long time, There is a problem that the user feels discomfort severely, thereby easily getting tired and unable to ventilate, and the like.

In order to solve the above problems, a backpack disclosed in Japanese Patent Laid-Open No. 10-2010-8756 (published on Jan. 25, 2010) includes a bag body capable of accommodating a gun and a shoulder strap for holding the bag body on a shoulder A plate member formed to be attached to a contact portion of the bag body and a back pressure protrusion formed so as to protrude from a contact surface of the plate member such that a plurality of protrusions protrude from the back surface of the bag body, ≪ / RTI >

However, the above-mentioned conventional art has a problem in that the efficiency of ventilation is reduced and the contact area between the back and the main body is reduced by using the acupressure projection having the massage function and the ventilation function is halved when the wind is not blown.

In recent years, a bag has been proposed which can accommodate an auxiliary bag made of a heat insulating material in a bag (or a 'backpack'). However, they are useful for maintaining the temperature of the product to some extent. However, It is inevitable that the contents are heated or cooled, and if they are not accommodated by cooling or heating the contents in advance from the beginning, there is a problem that cooling or heating effect is lowered.

The external temperature sensing unit 260 senses the temperature of the external environment and generates a control signal to provide a pleasant feeling to the user according to the external temperature.

For example, if the external temperature sensed through the external temperature sensing unit 260 is 25 ° C or higher, cooling is performed at the effective heat generation site of the thermoelectric element 230 to allow cooling through the delivery fan 220, When the temperature is less than 0 ° C, heat is generated at the effective heat generating portion of the thermoelectric element 230 so that heating is performed through the feed fan 220. In this case, the set temperature may be arbitrarily changed by a user or an administrator.

The bag body 30 has a storage space therein so that the original function of the bag can be performed.

The suspenders 40 are means for supporting the back 1 or the bag 1 formed on one side of the bag body 30 so as to be capable of sliding.

At one side of the suspenders (40), at least one pocket (42) capable of housing a portable accessory is formed.

For example, the pocket 42 is configured to accommodate a portable communication device, that is, a portable device such as a smart phone, a portable fan, a wired or wireless remote controller, and the like.

An on / off switch for controlling ON / OFF of the thermoelectric element formed in the device unit 20 and a setting switch for arbitrarily setting the set temperature can be provided on one side of the suspenders 40 The control panel 44 constituting various control switches of the control panel 44 is constituted.

In this case, the wireless remote controller may be interlocked with the control panel 44 to perform the on / off operation or the set temperature control of the device section 20 by the wireless remote controller.

In addition, the control panel 44 is provided with a fan operation switch for operating only the delivery fan 220, so that a pleasant feeling can be maintained according to the user's selection.

The use state of the bag which improves the above-described pleasant functioning will be described below.

First, as in the conventional case, the bag 1 is placed in the storage state through the storage space of the bag body 30, and the bag 1 is held by the suspender 40.

Thereafter, when the user desires to feel a pleasant feeling by the external temperature, he or she selects cooling or heating through the control panel 44 or the remote control unit formed on one side of the suspenders 40, and turns on. For convenience of explanation, it is based on air conditioning.

Thereafter, power is supplied to the delivery fan 220, the thermoelectric element 230, and the discharge fan 240 through the power supply unit 260.

Cooling is performed in the thermally conductive portion of the thermoelectric element 230 and cool air is blown through the ventilation hole 18 of the back portion 10 through the blower fan 220 located in the effective heat portion of the thermoelectric element 230 As a result, the back of the user who comes into contact with the backrest 10 is cooled to maintain a pleasant feeling.

The operation time of the thermoelectric element 230 may be controlled according to the user's selection through the control panel 44 or the remote controller or may be controlled according to the control signal of the external temperature sensor 270 have.

The heat generated by the thermoelectric element 230 is transmitted to the user through the feed fan 220 to maintain a pleasant sensation and the waste heat of the thermoelectric element 230 is separated by the diaphragm 212 The heat is quickly released to the outside through the discharge fan 250 installed in the discharge chamber 216 so that the thermoelectric element 230 is prevented from being heated by heat so as to prevent the thermal efficiency from being increased or damaged.

The solar cell module of the solar cell module 280 is formed on one side of the bag body 30 to collect or collect sunlight or solar heat through the solar cell panel to generate electric darkness, The energy is stored in the battery configured in the power supply unit 260 so that the power supply is smoothly performed.

In addition, since the socket for storing the portable battery is formed in the power supply unit 260, when the diary is not good, for example, even when the electric energy can not be generated through the solar battery panel, the power is supplied through the portable battery So that it can be used smoothly.
