[Problem that the idea aims to solve]

However, it is not suitable for painting or plating containers as described in Utility Model Application No. 63-37583. This method does not have sufficient heat retention effect, and also The thermal insulation effect using hot water as described loses its thermal insulation effect when the temperature of the hot water decreases. Therefore, in order to maintain the heat retention effect, you have to change the hot water each time, and you have to use your hands. The problem is that it takes time. Products using heat storage agents also have a short duration, so they cannot be kept warm. In order to maintain the effect, it is necessary to replace the heat storage agent, which is time-consuming.

[0005] The one using a surface heating element as described in Utility Model Application Publication No. 61-40370 is 10 It cannot be used for transportation because it cannot be used without a 0V household power source. Ma Also, because it is bag-shaped, there are limits to what can be kept warm, such as test tube racks. It cannot be used for anything.

[0009]

【Example】

Hereinafter, the transport heat insulator of the present invention will be explained with reference to the drawings. As shown in Figure 1, the transport heat insulator A is made of a synthetic resin molded body and is suitable for foods, pharmaceuticals, etc. , a heat-insulating container 1 for storing materials to be kept warm such as blood and cultured bacteria, and a material similar to the heat-insulating container 1. a lid body 2 made of material, a surface heating section 3 provided on the bottom of the heat insulating container 1, and a heat insulating container 1. The power supply for the battery storage section 4 provided in the It consists of a rechargeable battery 5.

0010 The materials for the insulation container 1 and the lid 2 are lightweight and have great insulation and heat retention effects. A foamable resin is preferable, such as foamed polystyrene, foamed polyurethane, or foamed polyester. Tyrene, foamed polypropylene, etc. are preferably used. The shape of the heat insulating container 1 and the lid body 2 can be selected according to the shape of the heat-insulated material to be stored. The shape of the heat insulating container 1 can be adjusted so that the material to be insulated can be easily put in and taken out. The lid body 2 is integrated with the heat insulating container 1 so as to cover the opening. Otherwise, it will be established separately.

[0011] The surface heating section 3 may be a wire resistor arranged in a planar manner on a predetermined sheet, or a carbon fiber. sheets with conductive fibers and metal fillers dispersed in nonwoven fabrics or synthetic resins, and conductive fillers. A conductive paint made by dispersing - in a thermosetting resin or the like can be used. In the case of sheets with carbon fibers, metal fillers, etc. dispersed in nonwoven fabric or synthetic resin For example, as shown in FIG. A pole part 32 and a terminal 33 are provided, and a lead wire 34 is connected to each terminal 33. The surface is made of a laminate layer 35 made of polyester resin or polyethylene resin. It is used as a heat generating part 3.

0012 After energization, the surface heating part 3 increases in temperature and eventually reaches the saturation point. The saturation temperature is determined by the specific resistance of the sheet material 31. Therefore, keep warm at a low temperature. If you want to use a material with high specific resistance as the sheet material 31, you want to keep it warm at a high temperature. In this case, a material with low specific resistance may be used as the sheet-like material 31. When using conductive paint, apply the conductive paint to the inner surface (side surface and/or Apply the resin to the specified thickness so that there are two ends (or the bottom surface), and then heat cure or After drying, attach electrodes to these ends, connect lead wires, and attach appropriate wood as necessary. Overcoat with fat. This type of conductive paint can handle voltages ranging from a few volts to several tens of volts. By applying a voltage, the temperature rises, but when it reaches a certain temperature, the resin expands. The tension causes the electrically conductive filler dispersed within the resin to come out of contact, and therefore electricity is cut off. Therefore, a temperature control unit such as a thermostat is not required. Use conductive paint The saturation temperature of the heated surface heating section 3 depends on the amount of conductive filler contained in the resin and the conductive coating. It can be determined by the thickness of the coating layer of the material.

[0013] The surface heating part 3 may be provided on either the inner surface of the heat insulating container 1 or the lid body 2, and a plurality of It may be provided. In particular, the surface heating portion 3 is 3, when placed on opposite sides of the insulated container 1, the inside of the insulated container 1 Since the air will be sandwiched between the surface heating parts 3 on both sides, the air will be released from the surface heating parts 3. Due to the influence of far infrared rays, air particles cause a so-called vibration absorption effect, which reduces the The warming effect increases.

[0014] The rechargeable battery 5 serves as a power source for the surface heating section 3, and is a lead-acid battery, nickel-cadmium battery, etc. Known rechargeable batteries such as aluminum batteries and nickel/zinc batteries can be used. A lead-acid battery is preferable in order to maintain heat for a long time. A battery storage section 4 for storing the rechargeable battery 5 is provided in the heat insulating container 1. Ru. The battery storage section 4 is appropriately provided at the bottom or side of the heat insulating container 1, and is used to store rechargeable batteries 5. For example, as shown in Figure 1, the insulated container 1 It may be stored in a recess provided on the inside of the bottom surface, and this recess may be covered with the plate member 7. As shown in FIG. Good too.

[0015] The connection between the rechargeable battery 5 and the surface heating section 3 is made when the surface heating section 3 is installed. It is also possible to provide a terminal part on the rechargeable battery 5 side at the position where the pole parts come into contact; It is desirable that the two terminals are connected via a switch 6 as shown in FIG. Swish For example, switch 6 can be switched between "keep warm" and "charge", and by pressing switch 6, When set to "Keep warm", the surface heating section 3 is electrically connected through the wiring 20 and 21, and the necessary The surface heating section 3 can be driven only when Also, set switch 6 to “charging”. In this case, the conduction between the rechargeable battery 5 and the surface heating part 3 is cut off, and the rechargeable battery 5 is It is connected to the charging socket 8. With switch 6 set to “Charging”, connect the charging socket. The rechargeable battery 5 can be charged by inserting the socket of the charger body 9 into the socket 8. becomes. At this time, by selecting an appropriate type of charger body 9, Alternatively, by switching the switch on the charger body 9, you can It goes without saying that it can be used with a variety of power sources, including 12-volt power sources such as power sources, automobiles, etc. .

[0016] Also, if you add an overcharging prevention function to the charger body 9, you will not have to worry about charging time. nothing. FIG. 4 shows a transport warmer B according to a second embodiment of the present invention. The transport heat insulator B includes the transport heat insulator A shown in FIG. The configurations of the rechargeable battery 5 and the rechargeable battery 5 are almost the same, but the insulation container 1 and the lid 2 are added to the cover. A battery housing section 4 is provided with an exterior case 10 for storing a rechargeable battery 5. is provided between the exterior case 10 and the heat insulating container 1.

[0017] The outer case 10 includes a lid 11 and covers the heat insulating container 1 to further enhance its heat insulating effect. Similar to the insulation container 1, the box body is made of foamed resin, and the film is made of flexible material such as PVC. Bag-shaped items laminated with foamed resin material, or coated with aluminum, etc., and laminated. Those that have been exported are used as appropriate. The outer case 10 includes a transport heat insulator A shown in FIG. Similarly, the switch 6 and the charging socket 8 can be provided via the wiring 20 and 21. I can do that. The functions of the switch 6 and the charging socket 8 are the same as that of the transportation warmer A in Figure 1. It's exactly the same. The wiring 21 can be removed from the terminal section of the surface heating section 3. , remove the insulating container 1 and the lid 2 portion excluding the rechargeable battery 5 from the outer case 10. It has become so.

[0018] The transport warmer B configured in this way is used to keep collected blood for testing warm and dry, for example. When transporting blood for testing, only the insulated container 1 is used within each hospital to collect and deliver blood. The insulated container 1 containing blood is set in the exterior case 10 provided in the vehicle for storage. Transport while keeping it warm. After arriving at the inspection facility, re-open from the outer case 10. The heat insulating container 1 is taken out and transported to a predetermined department. This makes the relatively heavy rechargeable Since there is no need to carry the battery 5 or the wiring, the weight burden on the collection and delivery staff can be reduced. .

[0019] Also, only the cargo compartment of an aircraft, where the temperature is always below room temperature during transportation, needs to be kept warm. In some cases, only the insulating container 1 and lid 2 are removed from the outer case 10 for collection and delivery. It is efficient to set it in the outer case 10 and keep it warm when it is loaded into the machine.
