Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a blowing type color changing device. More specifically, a blower type that takes in outside air from the suction port, discharges cold air from the discharge port, blows the cold air on a thermochromic material (for example, a toy such as a doll, a car, etc.), and thermally changes the thermochromic material. The present invention relates to a color changing device.
[0002]
[Prior art]
Conventionally, in this type of blowing type color changing device, for example, in Japanese Utility Model Laid-Open No. 4-80596, a refrigerant such as ice pieces or cold water is accommodated in a container, and air is passed through a metal pipe penetrating in the container. A thermochromic discoloration tool for a thermochromic toy having a structure that obtains cold air by circulation is disclosed. Japanese Utility Model Laid-Open No. 5-86400 discloses a blower-type color changing device having a structure in which a heat radiating portion is provided on the outer peripheral wall of a metal container containing a heat source and air is circulated through the heat radiating portion. ing.
[0003]
However, since both of the conventional blowing type color changing devices are configured such that the cold heat of ice pieces and cold water is indirectly transmitted to the circulating air through a metal member, the cooling efficiency tends to be lowered. . In particular, in an environment where the temperature is relatively high, sufficient cold air cannot be generated, and it is difficult to thermally discolor a thermochromic material in a short time.
[0004]
[Problems to be solved by the invention]
The present invention solves the above-mentioned conventional problems, and aims to provide a blowing type color changing device capable of improving the cooling efficiency and changing the color of a thermochromic material in a short time.
[0005]
[Means for Solving the Problems]
1) Outline The present invention is a blower type color changing device 1 that blows cool air to a thermochromic material 9 to discolor the thermochromic material 9, and is provided with a suction port 21 and a discharge port 22 on the outer surface of the casing 2. A cooling heat source chamber 3 in which a plurality of cooling blocks 31 are accommodated inside the casing 2 and an air blowing means 51 that causes external air taken in from the suction port 21 to flow through the cooling heat source chamber 3 and be discharged from the discharge port 22 as cold air. And the air flow passage in the cold heat source chamber 3 is bent by providing the partition wall 4 in the cold heat source chamber 3.
[0006]
With the above configuration, the external air taken from the suction port 21 can be sent into the cold heat source chamber 3 and allowed to pass through the cold heat source chamber 3 while being in direct contact with the cold heat block 31, thereby improving the cooling performance. In particular, in the present invention, the air flow passage in the cold heat source chamber 3 is bent by the partition wall 4 so that the air flow passage in the cold heat source chamber 3 is extended, and the contact amount between the cold heat block 31 and the circulation air is increased. Increasing the cooling performance further increases.
[0007]
2) Cold heat source room 3
It is preferable that the cooling block 31 is accommodated in the cooling source chamber 3 divided by the partition wall 4 in a randomly stacked state. In that case, in addition to the above-described effect that the air flow passage by the partition wall 4 is bent to improve the cooling performance, the air circulation gap formed between the cooling and heating blocks 31 becomes a complicated air flow passage that is bent in a complicated manner. Therefore, the cooling efficiency is further improved.
[0008]
In addition, it is preferable that the air flowing in the cold heat source chamber 3 is allowed to flow upward or downward in order to effectively pass between the stacked cold heat blocks 31 and increase the cooling efficiency. In that case, if the direction of the circulating air is alternately changed upward or downward by the partition wall 4, the limited space of the cold heat source chamber 3 can be effectively used for air cooling.
[0009]
3) Air blowing means The air blowing means 51 includes, for example, a centrifugal fan, an axial fan, a cross flow fan, etc. Among them, in order to allow air to pass through a narrow gap between the cooling blocks 31, a high discharge force A centrifugal fan (sirocco fan) having a high suction force is preferred. The position where the air blowing means 51 is provided in the casing 2 is any position of the air flow path between the cold heat source chamber 3 and the discharge port 22 or the air flow path between the cold heat source chamber 3 and the suction port 21. You may arrange in.
[0010]
4) Cold block The cold block 31 includes, for example, an ice block, a metal block, a cold storage agent block (a configuration in which a liquid cold storage agent is sealed with a thin plastic outer shell, also referred to as a cold block). It is done. The shape of the cooling block 31 may be any shape such as a sphere, a cone, a pyramid, a cube, a rectangular parallelepiped, and a ring. Moreover, it is good to cool the said metal lump and the said cool storage agent block with a refrigerator etc. previously. The ice block is preferable in that it can be easily obtained at home, and the cold storage agent block and the metal block are preferable in that the liquid can be used repeatedly without melting.
[0011]
5) Nozzle It is preferable to provide the flexible hose 6 at the discharge port 22 and provide the nozzle 7 at the tip of the flexible hose 6. The nozzle 7 can be moved freely by the flexible hose 6 and the discoloration work is facilitated. In particular, when the main body of the color changing device is large, it is not necessary to move the main body, and only the nozzle 7 needs to be moved. Further, the nozzle 7 preferably has a shape corresponding to the thermochromic material 9, and the opening amount of the gas discharge holes 72a is small when discoloring a small area of the thermochromic material 9, and discolors a large area. The case is large and is set appropriately. Further, it is preferable that the nozzle 7 is detachably provided on the flexible hose 6. Specifically, the nozzle 7 is attached to the flexible hose 6 by means such as fitting, screwing, and engagement. It is attached.

FIG. 1 is a longitudinal cross-sectional explanatory view along the air flow passage of the first embodiment, and FIG. 2 is a perspective view showing the internal structure of FIG.
[0014]
The casing 2 has a rectangular parallelepiped shape, and a suction port 21 and a discharge port 22 are opened on the outer surface. In the casing 2, the air blowing chamber 5 that communicates with external air from the suction port 21 and the cold heat source chamber 3 that communicates with external air via the discharge port 22 are in communication with each other via the air supply holes 52. They are connected in the horizontal direction.
[0015]
A flexible bellows-like flexible hose 6 is attached to the outside of the discharge port 22, and a detachable nozzle 7 is provided at the tip of the flexible hose 6. In addition, the flexible hose 6 may be a flexible tube made of soft rubber or soft synthetic resin that does not have a bellows portion.
[0016]
The air blowing chamber 5 is disposed on the side of the cold heat source chamber and communicates with the cold heat source chamber through the air supply holes 52. A blowing means 51 is provided inside the blowing chamber 5. Specifically, the blowing means 51 is configured by a fan 51a (specifically, a centrifugal fan) attached to a motor 51b connected to a power source (battery) 51c. And by the action | operation of the said ventilation means 51 (namely, rotation of the fan 51a), the external air taken in from the suction inlet 21 of the casing 2 is supplied in the cold-heat source chamber 3 from the air supply hole 52. FIG.
[0017]
The cold heat source chamber 3 is provided with a discharge port 22 and an air supply hole 52 at an upper portion thereof, communicated with the outside through the discharge port 22, and communicated with the blower chamber 5 through the air supply hole 52. . Further, a partition wall 4 is erected in the center of the cold heat source chamber 3, and the cold heat source chamber 3 is divided into two compartments. A communication hole 41 is provided at the lower end of the partition wall 4 so that the air flowing through the cold heat source chamber 3 first flows downward from the air supply hole 52 along the partition wall 4. After passing through 41, it flows upward to the discharge port 22. As a result, since the air flow path in the cold heat source chamber 3 is bent and extended, the amount of contact between the flow air and the cold heat block 31 increases, so that the flow air is sufficiently cooled in the cold heat source chamber 3. .
[0018]
An opening 32 for taking in and out the cooling block 31 is provided in the upper part of the cooling heat source chamber 3, and a removable cover is covered on the opening 32. In the drawing, ice blocks are housed in the cold heat source chamber 3 in a state of being randomly stacked.

(Example of heat discoloration)
FIG.5 and FIG.6 shows the discoloration state of the thermochromic material 9 at the time of using the ventilation type color-changing apparatus 1 of this invention. FIG. 5 is a doll in which hair and clothes are colored with a coloring material containing a thermochromic material. FIG. 6 shows an automobile whose body is colored with a coloring material containing a thermochromic material. Reference numeral 91 denotes a discolored portion.
[0028]
The thermochromic material 9 has a thermochromic portion colored on the surface with a coloring material containing a thermochromic material. As the thermochromic material, a reversible thermochromic material having a color change point (coloring point) at room temperature or lower (for example, 5 ° C. to 20 ° C., preferably 10 ° C. to 20 ° C.) is effective. A reversible thermochromic material comprising a chromatic organic compound, an electron accepting compound, and a color change temperature adjusting agent can be mentioned.
[0029]
In addition, the thermochromic material exhibits a large hysteresis characteristic due to a temperature change and exhibits tautomerism between a colored state and a colorless state, or between two different colored states, and the thermochromic portion of the surface changes due to the temperature change. A material having not only a color change but also a two-sided property that can freely select one of both modes before and after the change and maintain the mode at room temperature can be used effectively. More specifically, in the thermochromic material, the shape of the curve plotting the color density due to temperature change increases the temperature from the lower temperature side than the color change temperature range, and conversely from the higher temperature side than the color change temperature range. It is a type that changes its color by following a path that differs greatly from the case of lowering, and in the normal temperature range between the low temperature side color change point and the high temperature side color change point, it is below the low temperature side color change point or above the high temperature side color change point. It is possible to memorize and maintain the aspect changed at the temperature.
[0030]
Examples of the thermochromic portion include a configuration in which a thermochromic layer is provided on the surface by applying paint or ink containing the thermochromic material, or a configuration made of a synthetic resin mixed with a thermochromic material. A desired color or pattern is appropriately applied.
