Description

  The present invention relates to a portable simple air-conditioning apparatus that can be comfortably spent without using a cooler or the like and can be carried anywhere using a sheet containing a heat storage gel (heat storage gel).

  In recent years, awareness of global environmental protection and ecology has increased throughout the globe. In particular, awareness of energy conservation is increasing. Under such circumstances, a rug in which a heat storage material (cold storage material) is enclosed for the purpose of saving electricity bills or the like is known (see Patent Document 1).

  In this rug, a liquid heat storage material is enclosed in the rug, and the body temperature is absorbed by laying down on this sheet and lying down on it, giving the person who touched it a `` cool feeling '' . As a result, for example, there are effects that it is possible to eliminate the nightmare of hot midsummer nights and to reduce the use of cooling devices such as coolers.

  On the other hand, due to changes in the economic environment and rising gasoline prices in recent years, transportation companies and taxi companies are highly saving-oriented, forced to stop idling at breaks, and restricted use of air conditioners, etc. There are many examples of this.

  Certainly, if it is a rug as described in the said patent document 1, carrying around is also convenient and it is possible to bring it into various places freely and use it.

  However, when carrying the rug alone, it gradually absorbs the ambient temperature (atmosphere temperature), so when you actually want to use it, it already absorbs a considerable amount of heat, In many cases, it is not possible to obtain a "feeling". In particular, in a hot midsummer car, it often becomes warmer than the body temperature and is not useful.

  In addition, many people who are engaged in driving, especially truck drivers and taxi drivers, often have breaks and meals in their cars, but they do not have an air conditioner. In the in-vehicle environment, the body cannot be fully rested, and the employee is forced to work halfway. In other words, this may lead to a decrease in concentration while driving, and may cause a traffic accident.

  Therefore, the present invention combines a heat storage sheet containing a heat storage gel with a portable cold bag, so that it can be used comfortably at any time and anywhere, and a portable cold bag that provides both comfort and economy (energy saving). The present invention provides a portable simple cooling device that combines a sheet containing a heat storage gel.

  The present invention provides a heat storage sheet made of a flexible material that can be freely folded with a storage chamber for storing a gel having heat storage properties as a portable simple cooling device, a forced cooling means, and the forced cooling The above-described problem is solved by having a casing having a heat insulating layer capable of maintaining the cooling effect of the means and a portable cold insulation bag having a grip portion connected to the casing. To do.

  By adopting such a configuration, the heat storage sheet can be stored in the cold storage bag until the heat storage sheet is used, and absorption of heat of the atmosphere can be prevented until the heat storage sheet is used. Furthermore, since the cold insulation bag is provided with a forced cooling means, it can be used comfortably after long-term storage, and the heat storage sheet once used can be re-cooled.

  Moreover, it is preferable that the storage chamber is divided into a plurality of independent small rooms, and the gel is stored in each of the small rooms. With such a configuration, the gel bias due to use can be suppressed within a certain range, heat can be effectively absorbed, and cushioning can be ensured over the entire surface.

  Further, the heat storage sheet is configured to have first and second heat storage sheets having different sizes, the first heat storage sheet is used as a heat storage sheet for the trunk, and the second heat storage sheet is used for the head. If it is set as a thermal storage sheet | seat, while being able to arrange | position a 1st, 2nd thermal storage sheet | seat in a favorite position, only the necessary part can be cooled when needed, and it is suitable.

  Further, if the second heat storage sheet is provided with a fixing band for fixing to the headrest, for example, it can be firmly fixed to a “pillow” or “car headrest”, and the heat storage sheet is prevented from being displaced. Is possible.

  Further, since the forced cooling means includes a Peltier element and an electric fan for convection of air on the cooling surface of the Peltier element into the casing, cooling can be performed without requiring a refrigerant or a compressor. The back can be configured compactly.

  Further, by providing a cigar plug connected to the forced cooling means, a cigar lighter socket can be conveniently used as a power source for a cold insulation bag when used in an automobile.

  Further, if the forced cooling means is constituted by an introduction pipe for introducing cool air blown out from the air conditioner outlet of the automobile into the casing, the heat storage sheet can be cooled (cold) without requiring a separate power source. .

  Further, if the casing of the cold insulation bag is made of a flexible material and can be folded, the heat storage sheet can be made compact after taking out, and there is no problem with the storage location.

  By utilizing the present invention, the heat storage sheet can be comfortably used anytime and anywhere, and both comfort and economy (energy saving) can be achieved.

It can be securely fixed to a pillow or a car headrest. Reference numerals 18 and 28 denote edge portions as structures for protecting the peripheral portion and improving touch feeling.

  As shown in FIG. 2, a gel 12 having a heat storage property (gel, sometimes simply referred to as “gel” hereinafter) 12 is accommodated in the first heat storage sheet 10. Various gels can be used as long as the gel 12 has heat storage properties. For example, the gel 12 has a composition containing a water-absorbing polymer, parabens, fungicides, glycerin, water, a fragrance, and the like. Yes. This gel 12 has the property of depriving heat (temperature) by contacting a “thing” at a temperature higher than its own temperature, dispersing the heat deprived by the heat conduction in the gel 12, and releasing it to the outside. I have. Such a configuration is basically the same in the second heat storage sheet 20 except for the size.

  The gel 12 is sealed and accommodated in the accommodation chamber 11 formed in the first heat storage sheet 10. The storage chamber 11 is divided into a plurality of independent small rooms 11a. The small chambers 11 a are arranged in a lattice pattern on the first sheet 10.

  The covering material (surface) 14 that accommodates and covers the gel 12 includes an inner (gel 12 side) first covering material 14a and an outer second covering material 14b. In the present embodiment, the first covering material 14a is made of a polyamide fiber such as nylon (registered trademark) having excellent flexibility and strength. In the present embodiment, the second covering material 14b is a PVC (polyvinyl chloride) coating layer, and exhibits a dirt prevention function and a waterproof function during use. By adopting such a configuration, it can be folded freely as shown in FIG.

  The boundary portion 13 between the small rooms 11a arranged in a lattice shape is realized by heat-sealing the first covering material 14a, and the gel 12 moves between the adjacent small rooms 11a. It has a structure to prevent. In other words, the structure is such that the bias of the gel 12 during use can be suppressed within a certain range, heat can be absorbed effectively, and cushioning properties can be ensured over the entire surface.

  As shown in FIGS. 4 and 5, the cold insulation bag 30 has a casing (soft case) having a forced cooling means 32 and a heat insulating layer 31 a that can maintain the cooling effect of the forced cooling means 32. ) 31 and a hand belt (gripping part) 34 connected to the casing 31.

  The casing 31 is a so-called “soft case” and is flexible and can be folded and folded. The casing 31 has a three-layer structure in the present embodiment, and includes a heat insulating layer 31a, a front surface 31b, and a lining 31c. More specifically, the heat insulating layer 31a is preferably a foamed resin material such as urethane foam, styrene foam, or phenol foam from the viewpoint of improving portability (weight reduction). In consideration of durability and the like, the outer material 31b is preferably a polyamide fiber such as nylon (registered trademark). Furthermore, if a PVC (polyvinyl chloride) coating layer is provided, a waterproof function and an antifouling function can be exhibited. The lining 31c is provided for the purpose of preventing the heat storage sheets 10 and 20 to be in direct contact with the heat insulating layer 31a and simplifying care when it becomes dirty. it can. Furthermore, a thin aluminum vapor-deposited sheet or the like may be used in order to improve heat insulation performance and light shielding performance.

<Operation of portable air conditioner>
Hereinafter, the operation will be described assuming that the portable simple cooling device 1 according to the present invention is used in an automobile such as a truck or a taxi. Of course, it can be used not only in automobiles but also in bedrooms and sofas in the home and outdoors.

  Since the heat storage sheets 10 and 20 can be freely folded as shown in FIG. 3, the heat storage sheets 10 and 20 can be folded into the cold insulation bag 30 and stored compactly. The cold bag 30 is provided with a hand belt 34 (see FIG. 4), so it is easy to carry, and the cold bag 30 itself is a flexible soft case that can be folded so that it is difficult to place. There is nothing.

  Further, even if left in the automobile while being accommodated in the cold insulation bag 30, the casing 31 of the cold insulation bag 30 is provided with a heat insulating layer 31a over the entire surface (excluding the portion where the forced cooling means 32 is located). Therefore, it is possible to effectively prevent the heat storage sheets 10 and 20 from absorbing the ambient temperature in the vehicle. Further, since the cold insulation bag 30 according to the present invention is provided with the forced cooling means 32, the heat storage sheets 10 and 20 can be comfortably used even after long-time storage, and the heat storage once used is stored. It is also possible to re-cool the sheets 10 and 20. In addition, since the Peltier element is used, it can be cooled without requiring a refrigerant or a compressor, so that the cold insulation bag 30 can be configured in a compact manner.

  Furthermore, since the cold insulation bag 30 includes a cigar plug 38 electrically connected to the forced cooling means 30, a cigar lighter socket can be used as a power source for the cold insulation bag 30 when used in an automobile. is there.

  When the cigar plug 38 is inserted into the cigar lighter socket, the Peltier element and the electric fan start to operate. One electric fan functions to convect the air on the cooling surface of the Peltier element toward the inside of the cold insulation bag 30. The other electric fan functions to release air on the heat generating surface of the Peltier element to the outside (outside of the cold insulation bag 30). By such an action, the inside of the cold insulation bag 30 is forcibly cooled (cold).

  When the sheet is used, the heat storage sheets 10 and 20 are taken out from the cold insulation bag 30. After the heat storage sheets 10 and 20 are taken out, the cold insulation bag 30 can be folded small, so that it can be placed in a small space without getting in the way.

  As a specific example of use, as shown in FIG. 7, a user can comfortably take a nap by laying in a nap space behind the truck driver's seat 50 and lying on the nap. Of course, since it is not necessary to attach an air conditioner (cooler) provided to the truck at this time, idling stop can be realized, fuel cost can be saved, and environmental load can be reduced. Moreover, since the battery is not loaded, it has the effect of improving the battery life.

  Moreover, as shown in FIG. 8, the usage which attaches and uses the thermal storage sheet | seats 10 and 20 for the rear seat 54 of a motor vehicle, or the headrest 52 of a driver's seat is also possible. At this time, since the rubber band 21 is provided on the second heat storage sheet 20 attached to the headrest 52 of the automobile, the sheet can be firmly fixed without being displaced.

  In this way, by using the portable simple cooling device according to the present invention, it is possible to obtain a comfortable “cool feeling” at any time and anywhere, and it is possible to obtain a comfortable space while considering the economy and the environment. It has become.

<Other embodiments>
In the above, the rubber band 21 is used as a fixing band provided in the second heat storage sheet 20. By using a rubber band, attachment and removal are easy and adjustment is also simple. Of course, in addition to the rubber band, various types such as a Velcro fastener or a hole type adjustment band can be used.

  In the above description, the first coating material 14a is described as a polyamide fiber and the second coating material 14b is a coating layer of PVC (polyvinyl chloride). However, the present invention is not limited to this. As long as the gel 12 can be accommodated without leaking and the flexibility is not impaired, the structure may be three layers or more instead of two layers, or other materials may be used.

  In the above description, the description is based on the premise that a “cool feel” is obtained. On the contrary, it is also possible to function as a portable simple heating device by warming the seat. Such use makes it possible to warm up easily and economically, particularly in a winter vehicle.

  Moreover, although the forced cooling means 32 was set as the structure which had the Peltier device and the electric fan in the above, it is not restricted to this. For example, when used in an automobile, an introduction pipe for introducing cold air (or warm air) from an outlet of an air conditioner (cooler) installed in the automobile is provided, and the introduction pipe is connected to the cold insulation bag 30. May be adopted. If comprised in this way, the thermal storage sheet | seats 10 and 20 can be cooled (cold insulation) without requiring a separate power source, and it is convenient.
