Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bag type cooling device which is suitable for use as an automobile article.

[0002]

[Prior art]

 An ice box is the most common vehicle-mounted cooling device. In this method, a rigid heat insulating material is made into a box shape, and food and ice, etc. are put inside the box to keep it cool. Also, a small electric refrigerator may be used.

[0003]

[Problems to be solved by the device]

 By the way, since the ice box is made of a hard material, its outer shape remains unchanged even when not in use, making it unsuitable as an automobile product with a limited storage space for goods, so it can be easily carried anywhere. Not suitable for Furthermore, if a refrigerant such as ice melts or becomes warm, it cannot be cooled, which is not suitable for long-term cooling. In addition, an electric refrigerator can be used continuously for a long time, but it is not suitable for carrying because it is made of a rigid material, has the same inconvenience for storage, and is heavy. Therefore, the present invention aims to solve the problems.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the cooling bag cover according to the present invention is provided with a bag body made of a soft material that can be folded and a cooling member made of a Peltier element provided inside the bag body. It is characterized by

[0005]

[Action]

 When electricity is applied to the cooling member, the inside of the bag body is cooled by the Peltier element. Further, since the outer shape is a cooling bag, it can be carried relatively freely in any place. Further, when not in use, it can be folded to be stored with a small outer shape.

[0006]

[Effect of device]

 The cooling bag according to the present invention is characterized in that the bag body is made of a soft material so that it can be folded, and a cooling member including a Peltier element is provided inside the bag body. Therefore, when the cooling member is energized, the inside of the bag body can be cooled by the Peltier element, and moreover, continuous cooling for a long time becomes possible. Moreover, since the outer shape is a cooling bag, it can be carried relatively freely in any place. Furthermore, when not in use, it can be folded and stored to reduce the size. Therefore, it is suitable for use as an automobile article.

【Example】

 An embodiment configured as an automobile article will be described based on FIGS. 1 to 3. 1 is an enlarged sectional view taken along the line AA of FIG. 3, FIG. 2 is an enlarged sectional view taken along the line BB, and FIG. 3 is a perspective view of the present embodiment.

First, in FIG. 3, the cooling bag includes a bag body 1 made of campus cloth, and cord-shaped handles 3 and 3 are attached to the wide side surfaces 2 and 2, respectively. An opening that is opened and closed by a fastener 4 is provided at the top of the bag body 1. A breathable member 6 made of continuous polyurethane foam is provided near the bottom of the thickness side surface 5. However, the constituent material of the breathable member 6 is not particularly limited as long as it is a breathable material. A cord 7 for power supply extends from a corner of the breathable member 6, and a plug 8 connected to an on-vehicle power supply is attached to the tip of the cord 7. The cord 7 is folded when not in use, and is fixed by a band 9 provided at the center of the thickness side surface 5.

As is apparent from FIGS. 1 and 2, a frame 10 made of a suitable material having a relatively high rigidity such as plastic or aluminum is provided at the bottom, and a Peltier element is used at the center thereof. A cooling member 11 is provided, and power is supplied via the cord 7. The cooling member 11 is arranged with the heat generation side facing downward, and the upper cooling side thereof is in contact with the heat transfer plate 12. A fan 13 is provided in the frame 10 in the vicinity of the breathable member 6 to radiate heat generated from the cooling member 11 to the outside.

The heat transfer plate 12 is a substantially dish-shaped member made of a material having good thermal conductivity, such as aluminum, and serves as a mounting surface for articles, and a space above it serves as the article storage portion 14. A variety of articles, in this embodiment, 350 cc of canned goods such as canned juice and canned beer can be stored in a two-tier stack with the length direction oriented in the thickness direction of the bag body 1. However, the refrigerated goods 15 can be various things that require cooling, such as perishable fresh food.

A heat-insulating interior material 16 is provided inside the bag body 1 of the article storage unit 14. The heat-insulating interior material 16 is a member in which an aluminum foil is coated on the surface of a soft foam material, and it is difficult for the cold air inside to escape to the outside. As shown in FIG. 2, the upper portion of the heat-insulating interior material 16 has a lid 17 that covers the opening and is folded back from the left and right, and is overlapped with each other.

A fan 19 is provided above the article storage unit 14 and circulates the air inside the article storage unit 14 so as to make it uniform. The fan 19 is similar to the fan 13, and is made of a suitable type such as a sirocco fan. These are optimally driven by a common power source with the cooling member 11.

Next, the operation of this embodiment will be described. Refrigerates are put in the article storage section 14, the lid section 17 is closed with the hook-and-loop fastener 18, and the opening section of the cooling bag 1 is closed with the fastener 4. In this state, the cooling member 11 and the fans 13 and 19 are energized via the cord 7. As a result, the upper portion of the cooling member 11 is cooled and further transmitted to the entire article storage section 14 to cool the refrigerating material 15 in the article storage section 14.

At this time, cool air is circulated in the article storage unit 14 by the fan 19 for uniform cooling. In addition, the provision of the heat-insulating interior material 16 makes it difficult for the cold air to escape and improves the cooling efficiency. Further, the heat generated in the frame 10 is quickly exhausted to the outside through the breathable member 6 by the fan 13 and the temperature inside the frame 10 can be prevented from rising.

Since this cooling bag 1 is originally configured to be portable, it can be freely carried outside the vehicle by disconnecting the power supply. In this case, the cool effect can be expected for some time even if the power is removed. In addition, using a portable battery enables reliable cooling for a longer period of time.

Furthermore, since the bag body 1 and the heat insulating interior material are made of a soft material, the portion on the side of the article storage portion can be folded and made smaller when not in use. For this reason, it is most suitable for use in automobile products with limited storage space. However, it is not limited to being mounted on a vehicle, and can be used as a portable cooling device for various purposes such as household use.
