Embodiments of the present invention will be described below with reference to the drawings.

[First Embodiment] FIG. 1 is an exploded perspective view of a cooking cooler according to an embodiment of the present invention. This cooking cooler is intended for use mainly for rapidly cooling boiling water, heated dishes, baked cakes and the like to near room temperature.

[0015] As shown in FIG.
It is roughly divided into a main body 10 and an upper lid 30. When used, the upper lid 30 is put on the main body 10 to be integrated. At this time, the convex portion 32 of the upper lid portion 30 is in a state of being inserted into the slot 11 provided in the main body portion 10.

The main body 10 includes a fan 20 and a power supply 21.
Is attached. The power supply unit 21 includes a switch-equipped volume 22 and an AC adapter 2 that is plugged into a household outlet and converts commercial AC into low-voltage DC.
3 are provided. The switch-equipped volume 22 is
This is for turning on / off the rotation of the fan 20 and changing the rotation speed of the fan.

The fan 20 and the power supply 21 of the main body 10
The parts other than are molded integrally by blow molding plastic. On the left side of the main body 10, one vertical groove 13 having a large cross-sectional area is formed, and in the horizontal direction, a large number of horizontal grooves 14 having a shallower bottom than the vertical groove are formed in parallel with each other. The vertical groove 13 and the horizontal groove 14 are in a state where their upper parts are closed when the upper lid part 30 is covered. Thereby, an air flow passage through which air flows horizontally is formed between the main body 10 and the upper lid 30. In this state, when the fan 20 is turned on and rotated in the direction of sucking outside air, the air flows from the near side to the far side in the vertical groove 13, and flows into each lateral groove 14 at a portion connected to each lateral groove 14. Then, it flows from left to right, and is finally discharged to the outside from the right side of each lateral groove 14.

A portion of the main body 10 below the lateral groove 14 is hollow, and when water is poured from the water inlet 12, water can be stored in this hollow portion. That is, the hollow portion serves as a tank for storing water. FIG.
It is the perspective view which looked at the main-body part 10 from the back. On the back side of the main body 10, three grooves 15 are formed in the vertical direction. The depth of the groove 15 is such that it reaches the bottom of the lateral groove 14 on the front side. By providing such a groove 15, the strength of the plastic body 10 can be increased.

In this embodiment, the upper cover 30 is made of aluminum. This is because aluminum has a high thermal conductivity. However, other metals or other materials may be used as long as they have a certain degree of thermal conductivity, and the material that can be used for the upper lid 30 is not limited to aluminum.

FIG. 3 shows a state where the upper cover 30 shown in FIG. 1 is turned upside down. As shown in FIG. 3, a water guide sheet 40 is firmly adhered to the back side of the upper lid portion 30, and a vaporization sheet 41 is adhered to almost the entire surface of the water guide sheet 40.
FIG. 4 shows a state where only the water guide sheet 40 and the vaporization sheet 41 are spread. As the water guide sheet 40, a sponge made of, for example, PVA (polyvinyl alcohol) is used, and as the vaporization sheet 41, a thin cotton or paper that is well impregnated with water is used.

[0021] PVA sponge is characterized in that it can absorb more water than its volume. Further, the PVA sponge has a property that it has a large volume when it contains water, but shrinks when it is dry. However, by adhering the water guide sheet 40 made of PVA sponge to the back side of the upper lid 30, it is possible to prevent the shrinkage even when it is dry.

The water guide sheet 40 includes a projection 40a and a finger 40b, and the projection 40a is formed on the projection 32 of the upper lid 30.
Extending to Therefore, the upper cover 30 is connected to the main body 10.
When the protrusion 32 is inserted into the slot 11, the protrusion 40 a of the water guide sheet 40 reaches the bottom of the water tank in the main body, and is immersed in the internal water. When the protrusion 40a is immersed in water, the water is quickly sucked up from this portion by capillary action and spreads to the tip of the finger 40b. This water spreads further to the vaporization sheet 41,
The entire vaporized sheet becomes wet.

When using the cooler according to the present embodiment, after pouring water from the water inlet 12 of the main body 10, cover the upper lid 30 so that the convex portion 32 is inserted into the slot 11 of the main body 10. The power is turned on by the switch-equipped volume 22, and the fan 20 is rotated. Then, high-temperature water or food, which is the object to be cooled, is placed on the upper lid portion 30 while remaining in a kettle or a pot.

When the fan 20 is rotated, the air taken in from outside flows through the vertical grooves 13 and the horizontal grooves 14 and is finally discharged to the outside from the right side of each horizontal groove 14. During this time, the air flows in close contact with the water held in the vaporizing sheet 41. Therefore, the vaporization of the water held in the vaporizing sheet 41 is promoted, and the vaporized water is carried out together with the flowing air. When liquid water evaporates to a gas, it takes away heat of vaporization from the surroundings.

When 1 cc of water evaporates, it takes about 580 calories of heat from the surroundings. For this reason, when water evaporates quickly, the vaporization sheet 41 is rapidly cooled, and the upper lid 30 in close contact with the vaporization sheet 41 is also rapidly cooled. Thereby, high-temperature water and dishes placed on the upper lid 30 are also rapidly cooled through the pot and the like. At this time, the fan 20 only needs to be rotated relatively slowly because air that facilitates the vaporization of water needs to be circulated through the vertical groove 13 and the horizontal groove 14, so that power consumption is small.

In particular, if the temperature of the food in the pot is high enough to boil, the temperature of the water held on the vaporizing sheet 41 will also be close to 100 ° C., and vaporization will be further promoted. In other words, the higher the temperature of the pot or the like placed on the upper lid 30, the warmer the upper lid 30, whereby the vaporization of the water held on the vaporization sheet 41 is further promoted, and the vaporization heat taken away Thereby, the cooling effect of the pot and the like is further enhanced.

In some developing countries, due to sanitary problems,
There are areas where tap water cannot be used as drinking water. In such areas, tap water is boiled once,
It is common to cool it before using it for eating and drinking. In such a case, it takes a considerable time for the temperature of the water that has once boiled to drop to about room temperature, and it is difficult to cool down the water particularly in a hot summer time when a large amount of drinking water is required.

The cooler of the present invention is suitable for the purpose of rapidly cooling boiling water in such an area. Moreover, since it is simple in structure and can be manufactured at low cost, and has low power consumption and low operating costs, it can be easily obtained by general consumers in developing countries with relatively low economic levels. Also, there is no need to waste running water to cool food and drink.

By the way, tap water and the like contain impurities such as calcium, and if the water is continuously vaporized, residues such as calcium will precipitate. If the cooler of the present embodiment is used for a long time, the deposited residue prevents water from permeating, and the cooling effect is reduced. In the present embodiment, since water is vaporized from the vaporized sheet 41, the residue is deposited on the vaporized sheet and hardly precipitates on the water guide sheet 40 made of PVA sponge. In addition, since the vaporized sheet 41 and the water guide sheet 40 are separate bodies, when the residue is deposited on the vaporized sheet 41, if only the vaporized sheet 41 is replaced, the cooling effect returns to the original state, and The water guide sheet 41 made of PVA sponge, which is relatively expensive compared to the parts described above, can be used for a long period of time.

In the above description, the tank is provided in the main body 10, and the water introduced therein is sucked up by the water guide sheet and transmitted to the vaporizing sheet. However, the tank is not necessarily required. For example, sponge-like PVA is placed on the air flow passage, water is supplied from outside, and a pot or the like is placed on the top to cool. When the water in the PVA sponge is almost exhausted, it is also possible to supply water from above. In this way, the structure is simplified and the manufacturing cost can be reduced.

[Second Embodiment] Next, a cooking cooler according to a second embodiment of the present invention will be described. In the cooking cooler having the structure shown in FIG. 1 as the first embodiment, the temperature of the bottom part such as a pot placed thereon can be rapidly lowered, but the upper part of the pot etc. The temperature is less likely to drop compared to the part. FIG. 5 is a perspective view of a cooking cooler that improves this point.

The cooking cooler shown in FIG. 5 has a structure in which the top cover 30 of the cooler shown in FIG. 1 is replaced with a water tank 50, and the structure of the main body is the same as that of the first embodiment. It is. The water guide sheet 40 and the vaporization sheet 41 are attached to the bottom of the water tank 50 in the same manner as the cooking cooler of the first embodiment.

Water is filled in the water tank section 50, and a pot or a kettle to be cooled is put into the water as it is. The water tank unit 50 is provided with a propeller-shaped stirrer 51, and by rotating this, the water inside can be efficiently stirred. Although the principle of cooling is the same as that of the cooking cooler of the first embodiment, in the present embodiment, first, water in the water tank 50 is cooled by vaporization of water, and the cooled water becomes a cooling target. It differs from the first embodiment in that the pot and the like are cooled.

In the case of the cooler of this embodiment, the water in the water tank 50 is stirred by the stirrer 51 in
The water is cooled uniformly throughout. For this reason, since the pot etc. immersed in this water can also be cooled entirely from the surroundings, it is faster than the cooking cooler of the first embodiment,
Moreover, the dishes can be cooled uniformly.

Conventionally, when cooling a cooked dish, the whole pot was immersed in running water. However, in this case, water wasted wasted and there was a problem from the viewpoint of resource saving. However, in the present embodiment, there is an advantage that the whole can be uniformly cooled without wasting water.

In this embodiment, instead of putting water for cooling water into the water tank section 50, a dish to be cooled,
Boiling water that becomes drinking water may be directly added. In this case, the object to be cooled is directly cooled, and the whole is uniformly cooled by stirring, so that the cooling effect is further enhanced.

[Third Embodiment] The cooler according to the third embodiment of the present invention is a pet cooler. The pet cooler of this embodiment is similar to the cooking cooler shown in FIG. 1, and has the same basic structure as the cooking cooler of FIG. FIG. 6 is a plan view of the main body portion of the pet cooler with the upper lid removed, FIG. 7 is a plan view showing the back side of the upper lid, and FIG. 8 is a view of the upper lid shown in FIG. It is sectional drawing.

The main body except for the electric-related parts such as the fan 60 can be easily manufactured by blow molding, as in the cooking cooler of the first embodiment. The fan 60 provided in the main body takes in air from the outside and sends it out into the vertical groove 61. This air flows in the lateral groove 62 from left to right,
Finally, it is discharged from the outlet of the lateral groove 62 on the groove side.

The outlet 63 includes an AC adapter that is inserted into a household outlet and converts commercial AC into low-voltage DC, and is provided with a switch-equipped volume 64 and a light-emitting diode 65. The power converted to DC by the AC adapter is supplied to the fan 6 via the cord 66.
Sent to 0. The voltage of the current flowing through the cord 66 is between 5 and 12 sufficient to cause the fan 60 to rotate relatively slowly.
Since the voltage is as low as volts, even if the pets bite the cord and the conductive wires are exposed, there is no danger to the pet.

The water inlet 68 is a hole for pouring water into a water tank of the main body, and a handle 69 is provided for easy carrying. The handle 69 has a water inlet 68.
, Water is not spilled from the water inlet 68 even if the user takes the hand and lifts the whole.

On the back side of the upper lid 70, a PVA sheet 71 is adhered to the entire surface, and a vaporized sheet 72 made of cloth or paper is further stretched thereon. Also, on the back side of the upper lid 70, a projection 7 inserted into the slot 67 of the main body is provided.
3 are provided. The PVA sheet 71 has the protrusions 7.
3 and the PVA sheet 71 reaches the bottom of the water tank of the main body when the protrusion 73 is inserted into the slot 67.

When the upper lid 70 is put on the main body and the projection 73 is inserted into the slot 67, water is quickly sucked up by the capillary action of the PVA sheet 71 and spreads over the entire back side of the upper lid 70. This water is further transmitted to the vaporizing sheet 72, and the entire vaporizing sheet becomes wet.

When the fan 60 is rotated, the air taken in from the outside flows through the vertical grooves 61 and the respective lateral grooves 62, and evaporates from the right side of the respective lateral grooves 62 until it is discharged to the outside. It comes into close contact with the water held on the sheet 72. Therefore, vaporization of the water held in the vaporizing sheet is promoted, and the vaporized water is carried out together with the circulating air to the outside. When liquid water vaporizes into a gas,
In order to take away heat of vaporization from the surroundings, the aluminum upper lid 70 having high thermal conductivity is rapidly cooled. For this reason, if a pet sits on this, it can feel cool even in the hot summer time.

The pet cooler of the present embodiment has a simple structure as described above and can be manufactured at low cost.
Moreover, it has a sufficient cooling effect. Also, fans
It is sufficient to rotate at a relatively low speed, and since it is locally cooled, less power is used, and there is almost no noise as in a general indoor cooler. Further, since the structure is simple, for example, even if pet hair is clogged in the vertical groove 61 or the horizontal groove 62, the upper lid 70 can be easily removed and cleaned, and since the upper lid is made of aluminum,
There is also an advantage that even if the pet chews or scratches with a nail, it is hardly damaged.

[Fourth Embodiment] The cooler according to the fourth embodiment of the present invention is an outdoor cooler. Midsummer asphalt sidewalks and concrete poolsides are heated by direct sunlight. In particular, in the case of the poolside, walking barefoot causes pain when the temperature rises. The outdoor cooler according to the present embodiment is used to reduce the temperature of a place where the outdoor temperature becomes high as described above.

FIG. 9 is a plan view showing a state in which an outdoor cooling machine is installed on a sidewalk where a person walks to form a cooling sidewalk, and FIG.
FIG. 11 is a plan view showing a state in which a cooling lid 80 of a cooling sidewalk is removed, FIG. 11 is a cross-sectional view taken along AA ′ of FIG.
2 is a cross-sectional view taken along the line BB ′ in FIG. 10, and FIG. 13 is a plan view showing the back side of the cooling lid 80.

As shown in FIG. 9, 1 m × 1 m
Are arranged in a row to form a long sidewalk. An air outlet 81 for air is provided on the side of the sidewalk (upper side in FIG. 9). Cooling lid 8
As shown in FIG. 10, supports 82 are provided at a lower portion of 0 at intervals of 1 m at right angles to the direction in which the cooling lids 80 are arranged. Further, the support 8 is arranged in parallel with the direction in which the cooling lids 80 are arranged.
3 are provided. The supports 82 and 83 are provided with the cooling lid 8.
When arranging 0, it becomes a means to support this.

As shown in FIGS. 10 and 11, an air passage 84 is formed in the side portion in parallel with the support 83.
This is a passage through which air sent by a fan (not shown) passes. In the ground, a water pipe 85 is provided in parallel with the air path 84, and the water pipe 85 is provided with a water supply branch pipe 86 branched at each support 82. An insertion port 90 for inserting a projection 89 (see FIG. 13) of the cooling lid 80 is provided in a part of the water supply branch pipe 86. The water pipe 85 and the water pipe 86 are connected to the cooling lid 80.
For guiding the tap water to be supplied to the water guide pieces 87 attached to the back side of the water.

As shown in FIG. 13, a vaporizing sheet 88 is attached to the entire back side of the cooling lid 80, and is connected to a water guide piece 87 at a projection 89. When the projection 89 of the cooling lid 80 is inserted into the insertion port 90, the water guide piece 87 is also inserted at the same time, and is immersed in the water in the water guide branch pipe 86. The water guide piece 87 sucks up water by capillary action, and the sucked up water quickly spreads over the entire vaporizing sheet 88.

As shown in FIG. 11 and FIG.
When 0 is arranged, a small space 91 is formed below it. The air flowing through the air passage 84 flows laterally through the space 91. At this time, the air comes into close contact with the water held by the vaporizing sheet 88 to promote the vaporization of the water. When the front side of the cooling lid 80 is exposed to direct sunlight, the temperature of the cooling lid 80 rises due to the sunlight, and the vaporization of water from the vaporizing sheet 88 is further promoted.

As described above, when 1 cc of water evaporates,
Takes around 580 calories of heat from the surroundings. Therefore, when the water evaporates so actively, the temperature of the cooling lid 80 decreases rapidly. In particular, when the cooling lid 80 is made of a metal plate such as aluminum, the coldness is further increased. Thus, a person walking on this will feel cold through the soles, even when wearing shoes.

By the way, when water is supplied using tap water, the remaining calcium component after the water is vaporized is deposited on the vaporized sheet 88. When the precipitation amount of the calcium is large, water hardly permeates, and the cooling effect is reduced. For this reason, it is necessary to periodically remove the deposited calcium. For the removal of the descaling, a person may manually wash the back side of the cooling lid 80. For example, a liquid ejection mechanism is provided on the ground opposed to the cooling lid 80, and the desalting is performed from here. The weak acid solution may be periodically spouted to remove the scale. By doing so, it is possible to save the labor of manually cleaning the cooling lid 80 by a person.

In the above description, an example in which the cooling sidewalk is desired to be implemented is shown. However, if the present invention is applied to a poolside or the like as described above, even if it is midsummer, when walking on it barefoot, the pain caused by heat is felt. You don't have to. Further, the present invention is also effective when applied to, for example, an amusement park, a theme park, a rooftop of a department store, or the like, and can be used in a wide range of applications.

[Other Embodiments] The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention.

For example, in the description of the cooking coolers of the first embodiment and the second embodiment, the case where cooling of drinking water or cooked food is mainly described. However, in addition to this, it is also useful for cooling foods that solidify by cooling to room temperature, such as butter, konjac, and chocolate. Conventionally, it has been necessary to wait a long time until these are solidified. However, by using a cooking cooler, these can be solidified in a short time.

Further, for example, in a stall operating outdoors from spring to autumn, the cooking cooler of the first embodiment is formed in a table shape, and this is used as a table for placing food and drink. Can also. This way,
Even when eating and drinking outdoors in the hot summer months, there is an effect that food is hardly damaged.

In the description of the pet cooler of the third embodiment, the case where the pet is cooled has been described. In addition to this, for example, if the present invention is applied to a chair or a bench where a person sits on an outdoor stand, it can be used as a cooler for a person.

In the fourth embodiment, the case where the ground outside is mainly cooled has been described. However, the present invention is not limited to the outdoor but can be applied to, for example, cooling a floor for home use.

[0059]

As described above, the cooler of the present invention utilizes the fact that when water evaporates, it takes away heat from the surroundings.
By promoting the vaporization of water, with a simple structure, efficiently, without wasting cooling water such as tap water,
With less power consumption, it is possible to quickly cool cooked food, drinking water, animals, outdoor ground, floors, and the like.
