Some schools and businesses, such as catering centers that supply cooked food, cook large quantities of food at once. Large restaurant chains may also cook large amounts of food at once.

By the way, some dishes require a process of cooling overheated food once, but if the amount of cooking at a time increases, it takes a long time for the overheated food to cool to room temperature. . For this reason, in the past, for example, the whole pot was cooled by running water.

In addition, especially in developing countries, drinking tap water as it is poses a sanitary problem, so it is common to use tap water for boiling water, cool it, and then use it for drinking water. There are regions. In such a case, for example, the boiling water may be put in running water and cooled.

However, when cooling a large amount of dishes in running water, a large amount of tap water is wasted because cooling is usually performed while running tap water. Especially in developing countries, water is precious and it is economically problematic to wastefully discard it.

Hereinafter, the best mode for carrying out the invention according to the present application will be described with reference to the drawings. (First embodiment)

FIG. 1 is an exploded perspective view of a cooking cooler according to one embodiment of the present invention. This conditioning cooler is intended primarily for use in applications that rapidly cool boiled water, heated dishes, baked cakes, etc. to near room temperature.

As shown in FIG. 1, this cooking cooler 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 protrusion 32 of the upper lid 30 is inserted into the slot 11 provided in the main body 10.

The main body 10 is provided with a fan 20 and a power supply 21. The power supply section 21 is provided with a switch-equipped volume 22 and an AC adapter 23 which is inserted into a household outlet and converts commercial AC into low-voltage DC. The switch-equipped volume 22 turns on and off the rotation of the fan 20 and changes the number of rotations of the fan.

Portions of the main body 10 other than the fan 20 and the power supply 21 are integrally formed by blow molding plastic. A single vertical groove 13 having a large cross-sectional area is formed on the left side of the main body 10, and a large number of horizontal grooves 14 having a shallower bottom than the vertical groove are formed in parallel in the horizontal direction. ing. 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. Thus, 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 in the vertical groove 13 from the near side to the back side, and each horizontal groove It flows into 14 and then flows from left to right, and finally exits from the right side of each lateral groove 14.

The portion of the main body 10 below the lateral groove 14 is hollow, and water can be stored in this hollow portion by pouring water from the water inlet 12. In other words, this cavity serves as a tank for storing water. FIG. 2 is a perspective view of the main body 10 viewed 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 grooves 15, the strength of the plastic main body 10 is increased. Can be

In the present embodiment, the upper lid 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 as 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 tightly adhered to the back side of the upper lid part 30, and a vaporization sheet 41 is further pasted almost all over 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 guiding sheet 40, for example, a sponge made of PVA (polyvinyl alcohol) is used, and as the vaporizing sheet 41, a thin cotton or paper which is well impregnated with water is used.

PVA sponge is characterized by being able to absorb more water than its volume. The PVA sponge has a large volume when it contains water, but shrinks when it is dry. However, by adhering the water guide sheet 40 made of a PVA sponge to the back side of the upper lid portion 30, it is possible to prevent shrinkage even when it is dry.

The water guide sheet 40 includes a protrusion 40 a and a finger 40 b, and the protrusion 40 a extends to the protrusion 32 of the upper lid 30. Therefore, when the upper lid 30 is put on the main body 10 and the projection 32 is inserted into the slot 11, the projection 40a of the water guide sheet 40 reaches the bottom of the water tank in the main body. However, it will be immersed in the water inside. When the protrusion 40a is immersed in water, water is quickly sucked up from this portion by capillary action, and reaches the tip of the finger 40b. This water spreads further to the vaporizing sheet 41, and the entire vaporizing 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, the top cover 30 is inserted so that the convex portion 32 is inserted into the slot 11 of the main body 10. And turn on the power with the switch-equipped volume 22 to rotate the fan 20. Then, high-temperature water or food to be cooled is placed on the top lid 30 while being placed in a kettle or a pot.

When the fan 20 is rotated, the air taken in from the outside D

4 and finally discharged from the right side of each lateral groove 14 to the outside. 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 vaporization sheet 41 is promoted, and the vaporized water is carried out together with the circulating air. When liquid water vaporizes into gas, it takes away the heat of vaporization from its surroundings.

When 1 cc of water evaporates, it takes about 580 calories 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 rotate relatively slowly because the air that promotes the vaporization of water only needs to flow through the vertical grooves 13 and the horizontal grooves 14, so that the power consumption is low. I can do it.

In particular, if the temperature of the food in the pot is high enough to boil, the temperature of the water held in the vaporization sheet 41 will also be close to 10 Ot :, and vaporization will be further promoted. In other words, the higher the temperature of the pot placed on the upper lid 30, the higher the temperature of the upper lid 30, which further promotes the vaporization of the water retained in the vaporization sheet 41. The heat of vaporization that is taken away increases the cooling effect of pots and the like. In some developing countries, tap water cannot be used directly as drinking water due to sanitation concerns. In such areas, it is common to boil tap water once, cool it, and then use it for eating and drinking. In such a case, it takes a long time for the temperature of the water once cooled to reach room temperature, and it is difficult to cool down the water particularly in the hot summer months 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. In addition, it is simple in structure and can be manufactured at low cost, and has low power consumption and low operating costs, so that 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. Using the cooler of this embodiment for a long time In this case, the deposited residue impedes water penetration and reduces the cooling effect. 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. Moreover, since the vaporized sheet 41 and the water guide sheet 40 are separate bodies, if the residue is deposited on the vaporized sheet 41, the cooling effect will be restored if only the vaporized sheet 41 is replaced. Returning to the original, the water guide sheet 41 made of PVA sponge, which is relatively expensive compared to other parts, can be used for a long time.

In the above description, a 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 vaporization sheet. However, the tank is not necessarily required. For example, a sponge-shaped PVA is placed on the air flow passage, water is supplied from outside, and a pot is placed on the top to cool it. Then, when the water in the PVA sponge is almost exhausted, it is also possible to apply 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 fall than the part. FIG. 5 shows a perspective view of a cooking cooler in which this point is improved.

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. is there. The water guide sheet 40 and the vaporization sheet 41 are attached to the bottom of the water tank section 50 in the same manner as the cooking cooler of the first embodiment.

Water is filled in the water tank section 50, and the pot to be cooled, etc., is put into the water as it is. The water tank section 50 is provided with a propeller-shaped stirrer 51, and by rotating this, the water inside can be efficiently stirred. The principle of cooling is the same as that of the cooking cooler of the first embodiment. However, in this embodiment, the water in the water tank 50 is first cooled by the vaporization of the water, and the cooled water is used for cooling. Is different from the case of the first embodiment in that a pot or the like to be cooled is cooled. In the case of the cooler of the present embodiment, the water is uniformly cooled as a whole by stirring the water therein by the stirrer 51 in the water tank unit 50. For this reason, the pot or the like immersed in the water can be cooled from the surroundings as a whole, so that the dishes can be cooled faster and more uniformly than the cooking cooler of the first embodiment.

In the past, when cooling cooked dishes, the entire pot was immersed in running water.However, in that case, water was wasted and was problematic from the viewpoint of resource saving. However, the present embodiment has the advantage that the whole can be cooled uniformly without wasting water.

In this embodiment, instead of adding water for cooling water to the water tank section 50, a dish to be cooled or boiling water serving as drinking water may be directly added. In this way, 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 the present embodiment is similar to the cooking cooler shown in FIG. 1, and the basic structure is the same as the cooking cooler of FIG. Fig. 6 is a plan view of the body of the pet cooler with the top lid removed, Fig. 7 is a plan view showing the back side of the top lid, and Fig. 8 is the top lid shown in Fig. 7 cut at the center in the longitudinal direction. It is sectional drawing.

The main body, excluding the electric parts such as the fan 60, can be easily manufactured by blow molding, similarly to 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 flute 61. This air flows in the lateral groove 62 from left to right, and is finally discharged from the exit 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 pole 64 and a light-emitting diode 65. The power converted to DC by the AC adapter is sent to the fan 60 via the cord 66. The voltage of the current flowing through the cord 66 is a low voltage of about 5 to 12 volts, which is enough to rotate the fan 60 relatively slowly, so that the conductor may be exposed even if a pet bites the cord. However, there is no danger to pets. g The water inlet 68 is a hole for pouring water into the water tank of the main body, and a handle 69 is provided for easy carrying. Since the handle 69 is located near the water inlet 68, water does not spill from the water inlet 68 even if the handle 69 is used as a hand to lift the whole.

On the back side of the upper lid 70, a PVA sheet 71 is adhered to the entire surface, and a vaporization sheet 72 made of cloth or paper is further adhered thereon. On the back side of the upper lid 70, a projection 73 is provided to be inserted into the slot 67 of the main body. The PVA sheet 71 extends to the protrusion 73, and when the protrusion 73 is inserted into the slot 67, the PVA sheet 71 reaches the bottom of the water tank of the main body.

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 horizontal grooves 62, and finally is discharged from the right side of each horizontal groove 62 to the outside. It comes into close contact with the water held in the vaporizing sheet 72. This promotes the vaporization of the water held in the vaporizing sheet, and the vaporized water is carried out together with the circulating air to the outside. When liquid water evaporates to a gas, it takes away heat of vaporization from the surroundings, so the aluminum top lid 70 having high thermal conductivity is rapidly cooled. For this reason, if your pet sits on it, you can feel cool even in the hot summer months.

The pet cooler according to the present embodiment has a simple structure as described above, so that it can be manufactured at low cost and has a sufficient cooling effect. In addition, the fan only needs to be rotated at a relatively low speed, and because it is locally cooled, less power is required and there is almost no noise like a general indoor cooler. Furthermore, since the structure is simple, for example, even if the hair of the pet is clogged in the vertical groove 61 or the horizontal groove 62, the upper lid 70 can be removed and easily cleaned, and the upper lid is made of aluminum. Therefore, there is also an advantage that the pet is hard to be damaged even if the pet is stuck or caught by a nail.

(Fourth embodiment) The cooler according to the fourth embodiment of the present invention is an outdoor cooler. Mid-summer asphalt sidewalks and concrete poolsides are heated by direct sunlight. In particular, when walking by the poolside, walking barefoot, you will feel pain when the temperature rises. The outdoor cooler according to the present embodiment is used to lower the temperature in a place where the outdoor temperature becomes high.

FIG. 9 is a plan view showing a state in which an outdoor cooling machine is installed on a sidewalk where humans walk, thereby forming a cooling sidewalk. Fig. 11 is a cross-sectional view taken along line A-A 'in Fig. 10, Fig. 12 is a cross-sectional view taken along line B-B' in Fig. 10, and Fig. 13 is a back side of the cooling lid 80. FIG.

As shown in FIG. 9, a cooling lid 80 made of metal and having a size of l m × l m is arranged in a row at the top, forming a long sidewalk. An air outlet 81 is provided on the side of the sidewalk (upper side in FIG. 9). As shown in FIG. 10, support members 82 are provided below the cooling lid 80 at intervals of 1 m, at right angles to the direction in which the cooling lids 80 are arranged. A support 83 is provided in parallel with the direction in which the cooling lids 80 are arranged. The supports 82 and 83 serve as means for supporting the cooling lids 80 when they are arranged. As shown in FIGS. 10 and 11, an air passage 84 is formed in the side part 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 passage 84, and the water pipe 85 is provided with a water branch pipe 86 branched at each support 82. An insertion port 90 for inserting a projection 89 of the cooling lid 80 (see FIG. 13) is provided in a part of the water supply branch pipe 86. The water supply pipe 85 and the water supply branch pipe 86 guide the tap water supplied to the water guide piece 87 attached to the back side of the cooling lid 80.

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

As shown in Figs. 11 and 12, when the cooling lid 80 is placed, A jj space 91 is formed. 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. Further, when the front side of the cooling lid 80 is exposed to direct sunlight, the temperature of the cooling lid 80 rises due to sunlight, whereby the vaporization of water from the vaporizing sheet 88 is further promoted.

As mentioned above, when lcc water evaporates, it takes about 580 calories of heat from its 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. Therefore, a person walking on this feels 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. If the amount of precipitated khaki becomes large, water will not easily permeate and the cooling effect will be reduced. For this reason, it is necessary to periodically remove the deposited calcium. This descaling may be performed by a person manually cleaning the back side of the cooling lid 80.For example, a liquid ejection mechanism is provided on the ground facing the cooling lid 80, and the descaling is performed from here. A weakly acidic solution that melts may be jetted periodically to remove the scale. In this way, it is possible to eliminate the need for a person to manually clean the cooling lid 80.

In the above example, a cooling sidewalk was shown, but if it is applied to the pool side as described above, even if it is midsummer, it is not necessary to feel the pain of walking when walking barefoot on this . It is also effective when applied to, for example, amusement parks, theme parks, and the rooftops of department stores, and can be used in a wide range of applications.

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

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

Also, for example, in a food stall that is open outdoors from spring to autumn, the cooking cooler of the first embodiment can be formed in a table shape, and this can be used as a table for placing food and drink . In this way, even when eating and drinking outdoors during the hot summer months, the food is less likely to be damaged.
