Description

Technical Field

[0001] The present invention relates to a portable and simple type of portable air cooler that uses a plastic bottle filled with frozen water as a cooling body and combines it with a fan to supply cold air.

Background Art

[0002] As a conventional portable and simple air cooler, there is an air cooler having a hard double-structured container and a fan that blows air upward above the container. This air cooler is configured such that by having a cooling body and water inside the inner container, heat exchange is effectively performed between the air passing around the inner container, thereby improving the cooling efficiency of the air (see, for example, Patent Document 1). In addition, there is an air cooler having a hard container composed of an upper member such as resin and a lower member such as metal, with the lower member having a double structure, a fan that blows air from above the side surface of the cooling body to obtain cold air above the cooling body and cold air circulated internally, and a cold air outlet at the rear of the upper part of the container (see, for example, Patent Document 2). However, in the case of such an air cooler, in order to enhance the cold retention property of the container, the container is made of a hard material. Also, in the case of the suction method using the upper fan as in Patent Document 1, if the container is made of a flexible material, the cold air space on the side surface of the cooling body will be narrowed due to the decompression effect, so that a sufficient cold air space cannot be secured, and the container has to be made of a hard material. Therefore, in a state where the cooling body is not accommodated, there is a problem in terms of storage capacity that the hard material container makes it impossible to carry it in a compact manner. Also, in the case of the configuration where the fan in Patent Document 2 blows air from the side surface of the cooling body, there are problems such as not achieving a simple and compact overall configuration, not being excellent in design, and being inconvenient for carrying. Furthermore, there is a problem that the cost becomes high because a dedicated container is required.

[0003] Furthermore, there was a cooling fan that housed a cooling element in a container made of a flexible material with the top and one side open, and had a fan in the shape of a general handheld fan that blew air from the side of the cooling element, and a holder that held the fan and the bottom of the cooling element, with the fan's holder positioned on the outside of the cover (see, for example, Patent Document 3). However, with this type of air cooler, internally circulating cool air cannot be obtained; in other words, only cool air from above the cooling element can be obtained, resulting in insufficient cool air. Also, while the flexible container makes it somewhat compact when the cooling element is not housed, the presence of the retaining parts increases the storage volume. Furthermore, when the cooling element is housed and the fan is operating, the fan is configured to blow air from the side of the cooling element, resulting in an overall configuration that is not simple and compact, is not aesthetically pleasing, and is inconvenient to carry.

[0005] In view of these problems, the present invention aims to provide the following portable, simple air cooler. In other words, the configuration of the present invention provides sufficient cooling sensation through cool air passing through almost the entire surface of the cooling element, and enables a portable air cooler that can be compactly stored when the cooling element is not installed. Furthermore, even with the cooling element housed and the fan operating, the overall configuration remains compact and simple, resulting in a well-designed and portable air cooler. Furthermore, it enables the creation of low-cost air coolers that do not necessarily require dedicated or special containers. [Means for solving the problem]

[0006] The portable simple air cooler according to the first invention is a portable simple air cooler that generates cool air by blowing air and using a cooling element that is roughly cylindrical or polygonal in shape, and the portable simple air cooler is The device comprises a blower and a cover. The blower is substantially cylindrical, has an air outlet on its upper bottom surface, and is designed to blow air vertically upward. The cover is substantially cylindrical and made of a flexible material overall. The upper bottom surface of the cover is open, and the lower end of the cover is in close contact with the upper outer circumference of the blower, or in close contact with the upper side surface of the blower. The air blower unit comprises a fan unit that blows air vertically upward, a fan guard unit that protects the fan unit, a motor unit that rotates the fan unit, a battery unit that drives the motor unit, and a switch unit in the battery unit for controlling the rotation of the fan unit from the outside. The cover unit comprises a cover side section having a core layer of a flexible and self-supporting material.

[0007] The portable simple air cooler according to the second invention is a portable simple air cooler that generates cool air by blowing air and using a cooling element that is roughly cylindrical or polygonal in shape, and the portable simple air cooler is The device comprises a blower, an absorbent, and a cover. The blower is substantially cylindrical, with an open upper bottom surface or an air outlet on its upper bottom surface, and is designed to blow air vertically upward. The absorbent is substantially cylindrical, with an open upper bottom surface, and its lower end is in close contact with the upper outer circumference of the blower, or in close contact with the upper side surface of the blower. The cover is substantially cylindrical and made of a flexible material overall, with an open upper bottom surface, and its lower end is in close contact with the open upper outer circumference of the absorbent, or in close contact with the upper side surface of the absorbent. The air blowing section comprises a fan section that blows air vertically upward, a fan guard section that protects the fan section, a motor section that rotates the fan section, a battery section that drives the motor section, and a switch section in the battery section for controlling the rotation of the fan section from the outside. The absorption section comprises an absorbent side section made of a highly absorbent material, and a material that is air-permeable and has a highly absorbent shape, with the inner surface of the absorbent side section having inner surface Bottom position in Closely adjacent or above the lower end position in The cover portion comprises a closely fitted lower bottom portion, and the cover portion has a core layer of a flexible and self-supporting material, and a cover side portion, Cover partThe device is characterized by comprising an opening mechanism at the opening of the upper bottom surface, wherein the outer diameter of the upper part of the air blower, the outer diameter of the absorption part, and the outer diameter of the cover part are larger than the outer diameter of the cooling body, and the cooling body can be housed inside the hollow space formed by the absorption part and the cover part, and an air blowing space is formed between the absorption part and the cover part and the cooling body. [Effects of the Invention]

[0008] The present invention has the advantage of providing a portable, simple air cooler that is convenient to carry, as the entire unit becomes compact when the cooling element is not housed in it, by folding the cover. The portable, simple air cooler according to the present invention has a total volume that is almost entirely occupied by the air blower and the cooling element when in use. Furthermore, the fan section of the air blower and the airflow space between the cooling element and the cover section cause cool air to be blown upward from the opening at the top of the cover section. Therefore, even with the cooling element housed inside, it is possible to provide a simple air cooler that is compact and simple in configuration, making it convenient to carry and providing sufficient cooling. In addition, due to its simple configuration, it also has the effect of providing an air cooler with an excellent design. This invention makes it possible to use a commercially available PET bottle cover for the cover portion, resulting in the effect of providing a portable, simple air cooler that is easier to construct and has a lower cost.

[0009] The portable, simple air cooler according to the present invention, which has an absorption section, can evaporate condensation generated on the surface of the cooling element to the outside of the product in the absorption section. Therefore, especially when the rotation of the fan section of the air blower is stopped, it is possible to prevent adverse effects on the motor section and drive section of the air blower due to the dripping of moisture caused by the condensation, specifically short circuits and rust formation. Furthermore, when the fan section is rotating, it has the effect of providing a portable, simple air cooler that prevents water droplets that have dripped due to condensation from being scattered by the rotation of the fan section.

Modes for Carrying Out the Invention

[0011] Hereinafter, embodiments of the portable simple air cooler according to the present invention will be described with reference to the drawings. <Definitions in the Present Invention> In the present invention, "adhesion" includes both non-removable adhesion, i.e., adhesion by integral molding or adhesion by gluing or sewing, etc. even if they are separate parts, and adhesion that is removable by a detaching means and is in an adhered state.

Example

[0012] [Regarding the configuration of the portable simple air cooler of this example] The configuration of the portable simple air cooler of this example is as follows.

[0013] <Basic configuration of this example> FIG. 1 is a perspective view showing an example of a configuration diagram of a portable simple air cooler 1 in this example. FIG. 2 is a reference perspective view showing a usage state when a cooling body Ce is inserted into FIG. 1. FIG. 3 is a reference transparent perspective view shown to explain the structure of the portable simple air cooler 1 by making it partially transparent with respect to FIG. 1. FIG. 4 is a five-sided view of FIG. 1, where (A) is a front view, (B) is a plan view, (C) is a bottom view, (D) is a right side view, and (E) is a left side view. The rear view appears symmetrically left and right with the front view.

[0014] The portable simple air cooler 1 according to this example is a portable simple air cooler that generates cold air by blowing air and a cooling body Ce after inserting a cooling body Ce having a substantially cylindrical or substantially polygonal column shape. The portable simple air cooler 1 includes a blowing unit 11 and a cover unit 12.

[0015] Here, the cooling body Ce has an outer shape of a substantially cylindrical or substantially polygonal column shape, but may also have a shape that combines a substantially cylindrical shape and a substantially polygonal column shape. As an example, the cooling body Ce can be made of a PET (polyethylene terephthalate) material of a plastic bottle containing a cold storage agent or a frozen liquid, or made of metal (such as aluminum). However, it is not limited to such things, and any thing can be used as long as it has a function of cooling the outside air. Also, the size of the portable simple air cooler 1 into which the cooling body Ce is inserted can be any size as long as it is convenient for carrying. Here, as an example, the cooling element Ce is made to be the size of a typical 500ml PET bottle. The width and height of the cover portion 12 and the width of the air blower portion 11 are configured to form an air blowing space, which will be described later. In this way, the liquid inside a typical 500ml PET bottle that has been frozen can be used as the cooling element Ce. By using frozen plastic bottles as a cooling element (Ce), a cooling device can be prepared more easily.

[0016] The air blower 11 is substantially cylindrical in shape, Sending section 11 The upper bottom surface has an air outlet 111. The air blower 11 is for blowing air vertically upward. The blower unit 11 comprises a fan unit 112, a fan guard unit 113, a motor unit 114, a battery unit 115, and a switch unit 116. The fan unit 112 is for actually blowing air vertically upward. The fan guard unit 113 protects the fan unit 112, the motor unit 114 rotates the fan unit 112, and the battery unit 115 drives the motor unit 114. The switch unit 116 is located in the battery unit 115 and is for controlling the rotation of the fan unit 112 from the outside.

[0017] In other words, the motor unit 114 is rotated using power supplied from the battery unit 115, which in turn rotates the fan unit 112. The fan unit 112 blows air vertically upward in the positional relationship of the portable simple air cooler 1 shown in Figure 1, etc. In this embodiment, the number of blades is set to seven, as shown in Figure 4, etc., and the shape is as shown in Figure 4, etc. However, these are merely examples, and in the present invention, the number of blades and their shape are not limited to these. Any number of blades and shape is acceptable as long as they efficiently blow air vertically upward. The motor unit 114 can be either a relatively low-cost AC motor or a DC motor with high controllability and quietness. The battery unit 115 may be either a built-in dry cell battery or a rechargeable battery. Furthermore, although the battery unit is cylindrical in this embodiment as shown in Figure 1, the present invention is not limited to such a shape, and may also be polygonal prism in shape. The fan guard section 113 has the function of guarding the fan section 112 and is set on the side and bottom surface of the air blower section 11, as shown in Figure 4, etc. At the same time, it also functions as an air intake for drawing in air through the gaps in the fins of the guard. In this invention, the fan guard portion 113 is not limited to being present on both the side and bottom surfaces of the air blower portion 11, but may be present on only one side.

[0018] The cover portion 12 is roughly cylindrical and made of a flexible material overall. Cover part 12 The top and bottom surfaces are open. The lower end of the cover portion 12 is It is in close contact with the upper outer circumference of the air blower 11 or in close contact with the upper side surface of the air blower 11. The cover portion 12 comprises a cover side portion 121 and an opening / closing mechanism 122. The cover side portion 121 has a core layer of a flexible and self-supporting material. The opening / closing mechanism 122 is Cover part 12 This is an opening / closing mechanism located at the opening on the upper bottom surface. Figure 5 shows a reference diagram (plan view) of the device in the closed state of the opening / closing mechanism 122. Since the opening / closing mechanism 122 needs to be closed when the coolant Ce is inserted, Figure 5 shows that the opening / closing mechanism 122 is closed up to the cap Cp position of the coolant Ce.

[0019] The outer diameter of the upper part of the air blower 11 and the outer diameter of the cover 12 are larger than the outer diameter of the coolant Ce, and the structure is such that the coolant Ce can be housed in the hollow interior formed by the cover 12. As a result, an air blowing space is formed between the cover 12 and the coolant Ce.

[0020] To make the cover side portion 121 have a core layer made of a flexible and self-supporting material, this can be achieved, for example, by using a thin aluminum layer as the core layer. The cover 12 may be a dedicated product for the portable simple air cooler 1, or a commercially available PET bottle cover, as long as it satisfies the above conditions. If a commercially available PET bottle cover is used, the bottom portion should be cut off so that the air blower 11 can be attached. Cutting off the bottom portion is a relatively simple process. By using a commercially available PET bottle cover in this way, it becomes possible to construct a portable, simple air cooler 1 more easily. Furthermore, the opening and closing means 122 shown in Figures 1 to 5 are merely examples, and the opening and closing means according to the present invention may be any means. Also, if a commercially available PET bottle cover is used for the cover portion 12, the opening and closing means will be the PET bottle cover itself.

[0021] The portable simple air cooler 1 according to this embodiment has a first detachment means 14 that allows the cover portion 12 to be detached from the portable simple air cooler 1. That is, the first detachment means 14 allows the cover portion 12 and the air blower portion 11 to be detached. An example of the first attachment / detachment means 14 is shown in Figure 6. Figures 6(A) to (C) show an example of a means using hook-and-loop fasteners, and Figure 6(D) shows an example of a means using wire fasteners.

[0022] Figures 6(A) to (C) specifically show that the upper hook-and-loop fastener 141 is set on the upper layer Uy (corresponding to the cover part 12 in this case), and the lower hook-and-loop fastener 142 is set on the lower layer Ly (corresponding to the air blower part 11 in this case). The attachment surface 143 has a male and female (hook and loop) structure, making it possible to attach and detach it. Note that the attachment surface 143 does not need to have one side male and the other female; it is also acceptable to use two surfaces that are both male and female. Figure 6(A) has a simple structure, but it is not easy to attach or detach. In contrast, Figures 6(B) and 6(C) make attachment and detachment easier by using the external hook-and-loop fastener 144. Figure 6(C) makes attachment and detachment easier compared to Figure 6(B) by setting a guide part 145 on the lower layer Ly. Note that in Figure 6(C), the guide part 145 is integrated with the lower layer Ly, but it is also possible to set the guide part 145 on the lower layer Ly as an add-on. Even in the case of Figure 6(C), no processing is required on the upper layer Uy, so it is convenient even if the upper layer Uy is a commercially available PET bottle cover as described above. Although not shown in Figure 6(C), in the case of Figure 6(C), it is also possible to have a structure in which the upper layer Uy is partially fitted into the lower layer Ly before attaching the upper hook-and-loop fastener 141, the lower hook-and-loop fastener 142, and the external hook-and-loop fastener 144. Figure 6(D) specifically shows that the upper line fastener 146 is set on the upper layer Uy and the lower line fastener 147 is set on the lower layer Ly, and they are interlocked by teeth 148. This main line fastener is an open fastener because it is necessary to completely separate the upper layer Uy and the lower layer Ly. The upper line fastener 146 and the lower line fastener 147 correspond to the left and right zipper tapes, respectively. Note that for simplicity, the slider and opening mechanism are not shown in Figure 6(D). The first attachment / detachment means shown in Figure 6 is merely an example, and the first attachment / detachment means according to the present invention may be any means. The first detachment means 14 adds a function to the portable simple air cooler 1 that allows the cover part 12 to be replaced. In particular, if the cover part 12 is a commercially available PET bottle cover and an inexpensive one is used, the portable simple air cooler 1 can continue to be used by replacing the cover part 12 even if the cover part 12 is damaged or soiled.

[0023] <Regarding a configuration other than this embodiment> The present invention may not have a first detachable means, and the cover and the portable simple air cooler may be inseparable. In other words, the first detachable means is not an essential component of the present invention. Inseparable components include, for example, those in which the air blower and the cover are integrally molded, or those that are separate parts but are glued or sewn together. In a configuration different from this embodiment, the fan section is formed such that the airflow from the blower section is limited to the airflow space in the cover section, and / or Lower side of the upper bottom surface of the air blower unit It may also be a device that has a flow guide section formed in preparation for this. In other words, it is configured to efficiently blow air while minimizing unnecessary airflow. For simplicity, these configurations are not shown in Figures 1 to 6. The flow guide section is, Lower side of the upper bottom surface of the air blower unit It is a portable, simple air cooler designed to have an inverted mountain shape when viewed from the side. Lower side of the upper bottom surface of the air blower unit The center of it is raised downwards, and the base of the mountain shape is located at the lower inner end of the ventilation space. Lower side of the upper bottom surface of the air blower unit This is designed to guide the airflow that hits the center of the device towards the ventilation space. Furthermore, in a configuration different from this embodiment, the air blower unit blows air linearly upward in a vertical direction, in the opposite direction to the rotation direction of the fan unit. Spiral It may also be an object that has a shaped air outlet formed on it. Instead of forming them radially as shown in Figure 3, In the opposite direction to the rotation direction of the fan Spiral By forming an air outlet of a specific shape, the airflow from the fan is prevented from diffusing, resulting in efficient airflow. For simplicity, these configurations are not shown in Figures 1 to 6. If the fan rotates clockwise, then the airflow in the opposite direction... Spiral The shape is curved to the left from the center. Spiral It refers to the shape.

[0024] [Regarding the effects of this embodiment] The portable, simple air cooler according to this embodiment has a structure in which the air blower is located in the lower layer and the cover that houses the cooling element is located in the upper layer, so that cool air is blown upwards from the lower layer. Therefore, in the suction system, a flexible material is used for the cover to prevent the problem of the cool air space narrowing due to the pressure reduction effect when the cover is made of a flexible material. Therefore, when the cooling element is not installed, the cover can be folded to make the entire unit compact, providing a portable, easy-to-carry air cooler. Furthermore, the side sections of the cover, while flexible, are made of a self-supporting material, ensuring that the cooling system remains upright and does not malfunction when housing it.

[0025] The portable, simple air cooler according to this embodiment employs a vertical structure with an air blower in the lower layer and a cover in the upper layer that houses the cooling element. Therefore, when in use, the overall volume is almost entirely occupied by the volume of the air blower and the cooling element. Furthermore, the fan section of the air blower and the airflow space between the cooling element and the cover section allow cool air to be blown upward from the opening at the top of the cover section. Therefore, even with the cooling element housed inside, it is possible to provide a simple, portable air cooler that is compact and simple in configuration, and provides sufficient cooling. Furthermore, due to its simple configuration, it also has the advantage of being a well-designed air cooler.

[0026] The portable, simple air cooler according to this embodiment can use a commercially available PET bottle cover as the cover part. Therefore, it has the effect of enabling the construction of a portable, simple air cooler at a lower cost and in a simpler manner.

[0027] The portable, simple air cooler according to this embodiment can use a commercially available, frozen PET bottle containing liquid as the cooling element. Therefore, it has the effect of being able to construct a portable, simple air cooler at a lower cost and preparing the cooling element more easily. It also has the effect of allowing the user to consume the beverage inside without stopping the airflow.

[0028] The portable simple air cooler according to this embodiment has an opening with an opening / closing mechanism at the top of the cover, which has the effect of providing a portable simple air cooler that allows for easy removal and replacement of the cooling element and maintains the cooling state of the cooling element. Even if a commercially available PET bottle cover is used as the cover, the opening / closing mechanism of the PET bottle cover can be used.

[0029] The portable simple air cooler according to this embodiment can be equipped with a function that allows the cover to be replaced by the first detachable means. Therefore, especially when the cover is a commercially available, inexpensive PET bottle cover, the portable simple air cooler can be used continuously by replacing the cover even if it is damaged or soiled.

[0030] This embodiment provides a portable, simple air cooler, wherein the fan section is formed such that it limits the airflow from the air blowing section to the air blowing space in the cover section, and / or Lower side of the upper bottom surface of the air blower unit A flow guide section provided for this purpose has the following effects: In other words, by minimizing wasted airflow, it has the effect of enabling more efficient airflow.

[0031] This embodiment is a portable, simple air cooler, wherein the air blower unit blows air linearly upward in a vertical direction, in the opposite direction to the rotation direction of the fan unit. Spiral Designs with a specific shape for the air outlet have the following effects: In other words, it has the effect of preventing the diffusion of airflow from the fan section, allowing for more efficient airflow. [Examples]

[0032] [Regarding the configuration of the portable, simple air cooler in this embodiment] The configuration of the portable, simple air cooler in this embodiment is as follows:

[0033] <Basic configuration of this embodiment> Figure 7 is a perspective view showing an example of the configuration diagram of the portable simple air cooler 1 in this embodiment. Figure 8 is a reference perspective view showing the usage state when a cooling element Ce is inserted into Figure 7. Figure 9 is a reference transparent perspective view shown to explain the structure of the portable simple air cooler 1 by partially transmitting light to Figure 1. Figure 10 is a five-view drawing of Figure 1, where (A) is the front view, (B) is the top view, (C) is the bottom view, (D) is the right side view, and (E) is the left side view. The rear view is shown symmetrically to the front view.

[0034] The portable simple air cooler 1 according to this embodiment is a portable simple air cooler that generates cool air by blowing air and using a cooling element Ce that is roughly cylindrical or roughly polygonal in shape. The portable simple air cooler 1 comprises an air blower 11, a cover 12, and an absorbent 13.

[0035] The description of the coolant Ce is the same as in Example 1 and will therefore be omitted.

[0036] Regarding the air blower unit 11, Air blower unit 11 The top and bottom surfaces are open, or Air blower unit 11 Except for having an air outlet 111 on the upper bottom surface, the structure is the same as in Example 2, so the explanation will be omitted. The absorbent part 13 is substantially cylindrical, Absorbent part 13 The top and bottom surfaces are open. Absorbent part 13 The lower end is in close contact with the upper outer circumference of the air blower 11 or in close contact with the upper side surface of the air blower 11. The absorbent section 13 comprises an absorbent side section 131 and a lower bottom section 132. The absorbent side section 131 is made of a highly absorbent material. The lower bottom section 132 is made of a material that is airtight and also absorbent. On the inner surface of the absorbent side section 131, inner surface Bottom position in Closely or inner surface Position above the bottom end in They are closely related. In other words, the lower bottom portion 132 is set in close contact with the inner surface of the absorbing side portion 131, as shown in Figure 9. Furthermore, its setting position is at the lower end of the inner surface, or at a position somewhat above the lower end of the inner surface. The reason why the lower bottom portion 132 needs to be set at a position somewhat above the lower edge of the inner surface is that if the structure is designed to fit the absorption portion 13 into the air blower portion 11 to some extent, then the lower bottom portion 132 needs to be set at a position somewhat above the lower edge of the inner surface.

[0037] In this embodiment, as shown in Figures 9 and 10, the lower bottom portion 132 has a simple cross shape as an example. However, the present invention is not limited to this shape for the lower bottom portion; other shapes are also acceptable as long as they allow air to pass through, such as a finer mesh shape.

[0038] The cover portion 12 is roughly cylindrical and made of a flexible material overall. Cover part 12 The top and bottom surfaces are open. Cover part 12 The lower end is in close contact with the open outer circumference of the upper part of the absorbent part 13 or in close contact with the upper side surface of the absorbent part 13. The cover part 12 has a core layer of a flexible and self-supporting material, and a cover side surface 121, Cover part 12 It includes an opening / closing mechanism 122 at the opening position of the upper bottom surface. Figure 5 shows a reference diagram (plan view) of the opening / closing mechanism 122 in the closed position.

[0039] The outer diameter of the upper part of the air blower 11, the outer diameter of the absorption section 13, and the outer diameter of the cover section 12 are larger than the outer diameter of the coolant Ce, and the structure is such that the coolant Ce can be housed in the hollow interior formed by the absorption section 13 and the cover section 12. As a result, an air blowing space is formed between the absorption section 13 and the cover section 12 and the coolant Ce.

[0040] The rest of the description of the cover portion 12 is the same as in Example 2, so the description is omitted.

[0041] The portable simple air cooler 1 according to this embodiment has a first detachment means 14 that allows the cover portion 12 to be detached from the portable simple air cooler 1. In other words, in this embodiment, the first detachment means 14 allows the cover portion 12 and the absorbent portion 13 to be detached.

[0042] Details of the first attachment / detachment means 14 are the same as in Embodiment 2, except for the object to be attached / detached, so a description will be omitted.

[0043] The portable simple air cooler 1 according to this embodiment has a second detachment means 15 that allows the air blowing unit 11 and the absorption unit 13 to be detached.

[0044] Details of the second attachment / detachment means 15 are the same as those of the first attachment / detachment means 14, except for the object to be attached / detached, so a detailed explanation will be omitted. The second detachment mechanism 15 adds a function to the portable simple air cooler 1 that allows for the replacement of the absorbent part 13. In addition to cases where the absorbent part 13 is damaged or soiled, the portable simple air cooler 1 can be used continuously by replacing the absorbent part 13 that has become wet due to condensation with a dry absorbent part 13. The portable simple air cooler 1 can be used continuously by drying the absorbent part 13 that has become wet due to condensation separately. Furthermore, the first attachment / detachment means 14 and the second attachment / detachment means 15 do not need to be the same.

[0045] <Regarding a configuration other than this embodiment> The present invention may also be configured in a way that does not include a second detachable means, and the absorbent part and the portable simple air cooler are not detachable. Other than the above, the details are the same as in Example 1, so the explanation will be omitted.

[0046] [Regarding the effects of this embodiment] The portable, simple air cooler according to this embodiment can evaporate condensation generated on the surface of the cooling element to the outside of the product in the absorption section. Therefore, especially when the rotation of the fan section of the air blower is stopped, it is possible to prevent adverse effects on the motor and drive sections of the air blower due to the dripping of moisture caused by the condensation, specifically short circuits and rust formation. Furthermore, when the fan section is rotating, it has the effect of providing a portable, simple air cooler that prevents water droplets that have dripped due to condensation from being scattered by the rotation of the fan section.

[0047] The portable simple air cooler according to this embodiment can be equipped with a function that allows for the replacement of the absorbent part by means of a second detachment mechanism. In addition to cases where the absorbent part is damaged or soiled, the portable simple air cooler can be used continuously by replacing the absorbent part that has become wet due to condensation with a dry absorbent part. The effect is that the portable simple air cooler can be used continuously by drying the absorbent part that has become wet due to condensation separately.

[0048] Other effects are the same as in Example 1, so we will omit their explanation. [Explanation of symbols]
