[0002]

2. Description of the Related Art Conventionally, a heat storage heater incorporating a heat storage material and a heater for heating the heat storage material has been proposed, but this has the following problems.

First, since the heat storage material naturally radiates heat after storing heat from the heater, there is a limitation that the use time is immediately after heating or for a while after heating even if the heat storage material is covered with a heat insulating material. Could not be used for a long time.

[0004] In addition, since the heat storage material has only one heat radiation temperature, some users may complain that the temperature is too high or that the temperature is too low.

Also, depending on the material and thickness of the heat storage material and the coating material (heat insulation material) that covers the heater, the transfer of heat to the outside becomes poor, and it takes a long time to start up as a heat storage heating device and temperature unevenness occurs. There was a tendency to be easy.

Further, even when two types of heat storage materials having different heat radiation temperatures are used, there is a tendency that temperature unevenness is likely to occur depending on the arrangement of each heat storage material.

[0007] A heat storage heater provided with a heat storage material, a heater, and a coating material is heavier in weight and inconvenient to carry as compared with a heater using normal heater heating.

Further, since the conventional heat storage heater has an operation mode (operating method), the heat storage material has only a single function of heating the heat storage material with a heater and taking warmth with the heat.
Power supply to the heater from an outlet etc. is always necessary,
There was a problem that it could not be taken out outdoors with a cordless.

[0009]

Therefore, the present invention can be used for a long period of time, can select a plurality of heat radiation temperatures, has a fast start-up, is unlikely to cause temperature unevenness at the time of heat radiation, and requires one heater. It is an object of the present invention to provide a heat storage heater which can be used a plurality of times by heating, is convenient to carry, and can select several kinds of operation modes.

And a supercooling operation in which the heat storage material 1 is completely melted to enable supercooling.

[0021]

Embodiments of the present invention will be described below.

As the heat storage material (latent heat storage material) 1, a material having a large supercooling property is used. The heat storage material 1 having such a large supercooling property preferably has a degree of supercooling of 10 deg or more, whereby the supercooling of the heat storage material 1 can be easily controlled. If the degree of supercooling of the heat storage material 1 is less than 10 deg, the possibility of naturally releasing the supercooled state due to a decrease in temperature of the heat storage material 1 itself is increased, which is not preferable. Although the upper limit of the degree of supercooling of the heat storage material 1 is not particularly set, it can be set to 90 deg or less.

Specifically, the heat storage material 1 may be either organic or inorganic regardless of its type. However, from the viewpoint of having a large supercooling property, hydrates (particularly, peritectic systems) and pentaerythritol having a high-temperature (100 ° C. or higher) melting point can be suitably used. Since the heat storage material 1 having a supercooling property is used as described above, the heat storage heater of the present invention completely melts the crystal of the heat storage material 1 during heat storage by heating the heater 4 as shown in FIG. Heating by sensible heat can be performed.
Can be arbitrarily released by the release means 2 even after it has cooled down, whereby it is possible to heat it even after a while and use it for a long time,
In addition, heating can be performed without supplying power to the heater 4 and cordless use becomes possible.

In the present invention, a plurality of kinds of heat storage materials 1a, 1b,... Having different heat radiation temperatures when the heat is released by releasing the supercooling by the heat radiating means 2 are used as the heat storage material 1. The heat storage materials 1a, 1b,... Having different heat radiation temperatures can be formed by making their compositions different.

The release means 2 for releasing the supercooling of the heat storage material 1 may be of any type such as electricity and ultrasonic waves.
It is preferable to use a trigger 10 as shown in FIG. 3A so that the heat radiating means 2 can be used repeatedly and stably. The trigger 10 is provided with a trigger ring 12 on an upper surface of a bottom plate 11 and a trigger movable piece 13.
Is disposed inside the trigger ring 12, and the trigger movable piece 13 is provided in a concave portion 41 formed in the inner peripheral surface of the trigger ring 12.
By inserting the end of the movable movable trigger 13 in the concave portion 41, the washer 15 is disposed on the upper and lower surfaces of the movable movable trigger 13 and the movable movable trigger 13 is provided.
3 and the screw 14 after the screw 14
By screwing a nut 16 into the nut, the tip of the screw 14 is projected above the movable movable piece 13 to fix the screw 14 to the movable movable piece 13, and a holding plate 17 is screwed to the distal end of the screw 14. Is formed.

The trigger is provided in the heat storage material 1 as shown in FIG. 3B, and generates a nucleus of the heat storage material 1 with an external pressure P. That is, the external pressure applied to the pressing plate 17 causes the trigger movable piece 1 to move.
In this method, the nuclei are formed by aggregating the embryos of the heat storage material 1 deposited between the washer 15 and the washer 15 stacked thereon, and the heat storage body 3 is formed by sealing the heat storage material 1 and the trigger 10 in a container 18. Can be operated from outside, and the supercooling of the heat storage material 1 can be released.

Then, as shown in FIG.
8 are partitioned by a partitioning section 20 to form a plurality of rooms 6, one type of heat storage material 1a in one room 6, another type of heat storage material 1b in another room 6, and another room. By enclosing still another type of heat storage material 1c in one of the rooms 6 and arranging a trigger in one of the rooms 6 or all the rooms 6, the heat storage body 3 of the present invention can be formed. In FIG. 4, three chambers 6 are stored in one container 18.
Are formed, and three types of heat storage materials 1a, 1
Although the heat storage body 3 was formed using b and 1c, the number of the rooms 6 and the number of types of the heat storage material 1 are arbitrary.

The container 18 can be a bag-like one formed by lamination, and can be formed of, for example, a soft synthetic resin (eg, polyester, polypropylene, polyvinyl chloride, polyethylene, etc.).
Thereby, when the trigger 10 as described above is used as the release means 2, the trigger 10
And a plurality of partitions 20 can be easily formed by one sealing (welding) method, and can be divided into a plurality of chambers 6 easily. Further, in a case where a plurality of heat storage elements 3 are installed in one heat storage heater, the space for accommodating the heat storage elements 3 may be narrow. However, by forming the container 18 with a soft synthetic resin as described above, Since the shape of the heat storage body 3 is flexible, it can easily fit in a limited space. However, when the heat storage heater of the present invention is treated as a cushion, a load may be repeatedly applied to the heat storage element 3, or a large impact load may be applied to the heat storage element 3 due to jumping down of a child or the like. As shown in FIG. 17 (b), a protective container 21 made of a hard material such as a hard synthetic resin is used to form a container 18 which is a bag made of a flexible laminate and a heater 4 in contact with the container.
The above-mentioned problem can be prevented by enclosing the container in a protective container 21 and guarding the surroundings, and even if the container 18 is torn, the heat storage material 1 does not leak to the outside. The protection container 21 can prevent the heat storage material 1 from leaking.

The heater 4 may be a sheet-like heater having a plurality of heating wires 22 that generate heat when supplied with power from a household power source or the like. In addition, as the covering material 5 having heat insulation (heat insulation) and cushioning properties, a resin foam such as urethane foam formed in an arbitrary shape such as a plate shape can be used.

As shown in FIG. 1, the heat storage element 3 is built in substantially at the center of the coating material 5, and the heater 4 is brought into contact with the surface of the heat storage element 3 on both sides thereof. By incorporating it, the heat storage heater of the present invention can be formed. In this heat storage heater, heat is stored in the heat storage material 1 by heating by the heater 4, and the heat is generated by releasing supercooling of the heat storage material 1 by the release means 2 to use the heat.

In the present invention, the arrangement pattern of the heat storage element 3 and the heater 4 may be sandwiched by sandwiching one heat storage element 3 between the two heaters 4 as shown in FIG. 1 and FIG. Alternatively, as shown in FIG. 5 (b), the heater 4 may be provided so as to contact only one surface (lower surface) of the heat storage body 3, or as shown in FIG. May be sandwiched between two heat storage bodies 3 from both sides. However, in the case of FIGS. 5B and 5C, the heat storage 3 is heated by the heater 4 and at the same time heat is released from the heat storage 3 through the surface where the heater 4 is not provided. Preferably, the material 5 is used.

FIG. 6 shows another embodiment. This heat storage heater has two types of heat storage materials 1a, 1a having different heat radiation temperatures.
b, but the heat storage material 1a having the higher heat radiation temperature is provided outside the heat storage material 1b having the lower heat radiation temperature. That is, the heat storage material 1a having a high melting point
Is arranged outside the heat storage material 1b having a low melting point, and the heat storage material 1a having a high melting point is disposed on both sides of the heat storage material 1b having a low melting point, so that the heat storage body 3 is formed by sandwiching in the vertical direction (thickness direction). Have been. Other configurations are the same as in the above embodiment. As the heat storage material 1a having the higher heat radiation temperature, it is preferable to use a material having a heat radiation temperature (for example, 58 ° C.) higher than the temperature of the heated portion (the portion to be heated). As the heat storage material 1b having a heat radiating temperature, it is preferable to use a material having a heat radiating temperature (for example, 48 ° C.) suitable for heating the heated portion.

FIG. 7 shows a change in the surface temperature of the heat storage heater when the heat storage heater of FIG. 6 starts up (at the start of heating due to the radiation of the heat storage material 1). In this heat storage heater, first, the heat storage material 1a having the higher heat radiation temperature disposed outside (around) is released from the supercooled state to release heat,
This heat release heats the coating material 5 at once (shown by a solid line in FIG. 7). Thereafter, the heat storage temperature of the heat storage material 1a rapidly decreases. At substantially the same time, the heat storage material 1b disposed on the inner side (core) and having the lower heat release temperature is released from the supercooled state. As a result, the coating material 5 is heated to an appropriate temperature suitable for heating (indicated by a dotted line in FIG. 7). Accordingly, as shown by the dashed line in FIG. 7, the heat storage heater has a shorter time until its surface temperature becomes a heat radiation temperature suitable for heating the heated portion, and can improve the start-up property. It is. FIG. 7 shows the change in the surface temperature of the heat storage heater when only the heat storage material 1b having a heat radiation temperature suitable for heating the heated portion is indicated by a two-dot chain line. In this case, as compared with the heat storage heater of the present invention, it takes a longer time to reach a surface temperature suitable for heating the heated portion.

FIGS. 8A to 8C show other examples of the heat accumulator 3. This heat storage unit 3 is formed having rooms 6a and 6b having different capacities, and the room 6a having a larger capacity is used.
The heat storage materials 1a and 1b having different heat radiation temperatures are sealed in the small capacity room 6b. In this case, the heat storage material 1a having the higher heat radiation temperature in either of the rooms 6a and 6b.
8, the heat storage material 1a having a higher heat radiation temperature (a heat radiation temperature higher than that of the portion to be heated) is sealed in the room 6a having the larger capacity, and the room 6a having the larger capacity has the smaller capacity. The heat storage material 1b having the lower heat radiation temperature (heat radiation temperature suitable for heating the heated portion) is sealed in the room 6b. The rooms 6a and 6b are connected by a connecting piece 23, and the rooms 6a and 6b are formed in a communicating state by a communication path 7 formed in the connecting piece 23. And
Although the heat storage material 1a and the heat storage material 1b are in contact with each other in the communication path 7, the heat storage material 1a sealed in one room 6a (6b) is prevented from invading the other room 6b (6a).
The communication path 7 is preferably formed to have a small diameter.
The heat storage material 1a and the heat storage material 1b can be prevented from mixing. The release means 2 (trigger 10) is provided in a room 6a in which the higher heat storage material 1a is sealed.
The heat storage materials 1a, 1b,.
Is used, the release means 2 is arranged in a room in which the heat storage material having the highest heat radiation temperature is sealed.

The heat storage body 3 thus formed can be used for a heat storage heater in the same manner as described above.
After a and 1b are supercooled, they can be removed from the heat storage heater and used alone or attached to another heat storage heater. In this heat storage body 3, the heat storage materials 1a, 1
In releasing heat from the supercooling of the room 6b, first, as shown in FIG.
In addition, the connecting piece 23 is bent so as to overlap the heat storage material 1a, and the room 6a is bent so that the room 6a overlaps the other surface of the room 6b.
The sandwich 6 is sandwiched between both sides of the room 6b in which b is enclosed. After folding the heat storage body 3 in this way, the release means 2 is operated to release the heat of the outer heat storage material 1a. Thereafter, the crystallization of the heat storage material 1a
And the heat storage material 1b dissipates heat. As described above, in this heat storage body 3, the heat storage material 1a is operated by one operation of the release means 2.
And the heat storage material 1b can be easily dissipated. Note that the heat releaser 2 may be operated to release the heat without folding the heat storage body 3 as described above. In the room 6, a reinforcing portion 24 is provided at a bent portion so as not to be damaged by bending.
Is preferably provided.

FIG. 9 shows another example of the heat storage body 3. This heat storage unit 3 is the same as that shown in FIG.
b are formed in substantially the same size, and each room 6
The heat storage materials 1a and 1b enclosed in the heat storage materials 1a and 1b are gelled by a gelling agent, and the fluidity of the heat storage materials 1a and 1b is reduced. As the gelling agent, for example, polyvinyl alcohol (PVA) or xanthan gum can be used. The communication path 7 is filled with a sealing material 8. The sealing material 8 has the same or similar crystal shape as the heat storage materials 1a, 1b sealed in the adjacent rooms 6a, 6b, and is filled in the rooms 6a, 6b adjacent to the communication path 7. 1b, which is formed of a non-gelled material having a degree of supercooling equivalent to that of the heat storage material 1a or the heat storage material 1b containing no gelling agent.
Can be prepared using the same materials as described above. Also, the sealing material 8
Are the heat storage materials 1a, 1 enclosed in the adjacent rooms 6a, 6b.
The communication path 7 is filled so as to come into contact with b.

The heat storage body 3 thus formed can be used for a heat storage heater in the same manner as described above.
(B) The heat can be dissipated in the same procedure as in (c).
In the heat storage body 3, since the heat storage materials 1a and 1b sealed in the respective rooms 6a and 6b are gelled by the gelling agent, the fluidity of the heat storage materials 1a and 1b can be reduced, and The heat storage material 1a sealed in one room 6a (6b) can be made difficult to penetrate into the other room 6b (6a) through the communication passage 7 of the above, whereby the heat storage material 1a and the heat storage material 1b are mixed. It is something that can not be done. Moreover, the heat storage material 1a sealed in the one room 6a (6b) through the small-diameter communication passage 7 can be made hard to penetrate into the other room 6b (6a) by the sealing material 8, and the heat storage material 1a and the heat storage material 1b can be prevented from being mixed, and furthermore, since the sealing material 8 has the same or similar crystal form as the heat storage materials 1a and 1b, only the crystallization of the heat storage material 1a is performed by the sealing material 8 to the heat storage material 1b. In addition, the crystal form similar to the heat storage materials 1a and 1b refers to the average size (a × b × c) of the crystal lattice of the heat storage materials 1a and 1b.
^1/3 Average size of the crystal lattice of the sealing material 8 is 0.5 for
It means within 1.5 times. The above a,
b and c are lattice constants.

FIG. 10 shows another example of the heat storage body 3. This heat storage body 3 is formed in the same manner as that shown in FIG.
As the sealing material 8 filled in the heat storage material, a gelled heat storage material may be used, or the heat storage material 1a sealed in each room 6 may be used.
1b can be formed of a material that suppresses the flow of the fluid in the communication path 7. As the gelled heat storage material for forming the sealing material 8, the same material as the heat storage materials 1a and 1b gelled with the above-mentioned gelling agent used in FIG. 9 can be used. . When the sealing material 8 is formed of a material that suppresses the flow of the heat storage materials 1a and 1b in the communication path 7, a material that swells by impregnating the heat storage materials 1a and 1b can be used. A nonwoven fabric, a woven fabric, a communicating (breathable) sponge, or the like can be used.

In the heat storage unit 3, the heat storage material 1a sealed in one room 6a (6b) through the communication path 7 by the sealing material 8 is less likely to penetrate into the other room 6b (6a). As a result, the heat storage material 1a and the heat storage material 1b can be prevented from being mixed, and the sealing material 8 includes the gelled heat storage material or the heat storage material 1a, 1b sealed in each of the chambers 6a, 6b. Since the swelling material is used, only the crystallization of the heat storage material 1a propagates through the sealing material 8 to the heat storage material 1b. The heat storage materials 1a and 1b sealed in the respective rooms 6a and 6b may be gelled or may not be gelled. Moreover, the heat storage body 3 formed in this way can be used for a heat storage heater in the same manner as described above.

FIGS. 11A, 11B and 11C show another example of the heat storage unit 3, in which one room 6 is formed. In these heat accumulators 3, distances between a plurality of portions of the heat accumulator 1 and the release means 2 (the propagation of crystallization) so that the heat accumulator 1 sealed in the room 6 radiates heat almost uniformly over the whole. (Distance) is substantially equal. As shown in FIG. 11 (d), when the release means 2 is disposed at the corner of the substantially quadrangular heat storage body 3, when the supercooling is released by the heat release means 2, the heat storage material 1 starts from a portion close to the heat release means 2. Is generated, and the crystallization gradually spreads as indicated by the arrow, so that the heat storage body 3 radiates heat throughout. Therefore, the propagation speed of the crystallization of the heat storage material 1 is deviated, and the corner of the heat storage body 3 provided with the release means 2 radiates heat fastest. At the opposite corner, heat is radiated at the latest, and immediately after the start of heat radiating, the heat storage body 3 cannot be radiated almost uniformly over the whole.

Therefore, in the heat storage unit 3 shown in FIG. 11A, the room 6 is formed in a substantially circular shape, and the release means 2 is disposed substantially in the center of the room 6 (heat storage unit 3). 1 is formed. In this heat storage element 3, the crystallization of the heat storage element 1 propagates almost uniformly and radially from the substantially central portion of the heat storage element 3 as indicated by an arrow by releasing the supercooling of the heat storage element 1 by the release means 2. The heat storage material 1 sealed in the room 6 can be dissipated almost uniformly over the entirety without bias.

In the heat storage unit 3 shown in FIG. 11B, a storage unit 26 is formed at a corner of the heat storage unit 3 and a room (main heat radiation unit) 6 having a larger capacity than the storage unit 26 is formed. Part 2
6 and the room 6 are communicated by a plurality of propagation paths 42, the release means 2 is provided in the storage section 26, and the heat storage material 1 is sealed in the storage section 26, the propagation path 42 and the room 6. The propagation path 42 is formed so that the storage section 26 and a plurality of portions of the room 6 communicate with each other. In the heat storage unit 3, when the supercooling of the heat storage material 1 in the storage unit 26 is released by the release unit 2, the crystallization generated by the release is propagated to a plurality of portions of the room 6 through the propagation path 42 as indicated by arrows. Thus, crystallization occurs in the large area of the room 6, and the heat storage material 1 sealed in the room 6 is released from supercooling to radiate heat. In the heat storage unit 3, the length of the propagation path 42 communicating with the portion of the room 6 close to the release means 2 and the length of the propagation path 42 communicating with the portion of the room 6 far from the release means 2 are substantially matched. Is formed by meandering the propagation path 42 communicating with the portion of the room 6 close to the release means 2, whereby the supercooling of the heat storage material 1 in the storage section 26 by the release means 2 is released. 1 is propagated from the storage section 28 to the plurality of portions of the room 6 through the propagation path 42 almost simultaneously, and the heat storage material 1 sealed in the room 6
The crystal can be ejected to a plurality of portions at a time, and the heat storage material 1 sealed in the room 6 occupying the large area of the heat storage body 3 can be radiated almost uniformly over the entirety without bias. is there.

The heat storage unit 3 shown in FIG. 11C has a substantially circular storage space 26 in plan view and a room (main radiator) 6 having a larger capacity than the storage space 26 in a substantially circular shape in plan view. And the storage section 26 and the room 6 are disposed vertically, and the storage section 2
6 and the room 6 are communicated by a plurality of propagation paths 42 of the same length, and the release means 2 is disposed in the storage section 26.
It is formed by enclosing the heat storage material 1 in the room 6, the propagation path 42, and the room 6. 11B, when the supercooling of the heat storage material 1 in the storage unit 26 by the release means 2 is released, the crystallization of the heat storage material 1
And propagates almost simultaneously to a plurality of portions of the room 6 through the propagation path 42. Crystals can be ejected at a time to a plurality of portions of the heat storage material 1 sealed in the room 6,
Thermal storage material 1 enclosed in room 6 occupying a large area of thermal storage body 3
Can be dissipated almost uniformly throughout the entirety.

Incidentally, the heat storage body 3 formed as in 11 (a), (b) and (c) can be used for a heat storage heater in the same manner as described above.

FIG. 12 shows another example of the heat storage body 3. The heat storage body 3 has two rooms 6, and a heat storage material 1a having a higher heat radiation temperature is provided in one room 6 and a heat storage material 1b having a lower heat radiation temperature is provided in the other room 6, respectively. It is enclosed. In addition, release means 2 is provided at the end of each room 6.
Are arranged respectively. Further, the room 6 is completely separated by a partition 20 formed in a meandering state.
In other words, even if the supercooling of the heat storage material 1a (1b) sealed in the room 6 is released by the release means 2 provided in one room 6 to release heat, the heat storage material 1b (1) sealed in the other room 6 is released.
In order to prevent crystallization of a), the heat storage materials 1a and 1b sealed in each room 6 are completely separated. Each room 6 is formed in a substantially comb shape in plan view, and is formed so as to mesh with each other.

In the heat storage body 3, since the heat storage materials 1a and 1b and the releasing means 2 for releasing the supercooling thereof are provided in each of the rooms 6, the heat storage material 1a and the heat storage material 1b can be individually radiated. It can be used multiple times (heating). By using the heat storage materials 1a and 1b having different melting points and different heat radiation temperatures, the heat storage material 1 in a desired temperature range can be radiated according to the situation. Furthermore, since each room 6 is formed in a substantially comb shape in a plan view and arranged so as to mesh with each other, only one of the heat storage materials 1a (1b) is radiated, so that even if the heat storage material 3 is used a plurality of times, the heat storage material 3 is almost always formed. The whole can be brought to a uniform temperature. The number of rooms 6 is arbitrary. Further, one kind of heat storage material 1 may be sealed in all the rooms 6, and the number of kinds of heat storage material 1 is arbitrary.
