Description

Technical Field

[0001] The utility model relates to a water evaporation type air cooler, in particular to an air cooler with excellent cold air persistence, which is configured to keep the temperature of water cold for a long time by improving the heat insulation of a water tank when using cold water by using an ice bag, so that cool air can be continuously blown out even when the air cooler is used for a long time. Background Art

[0002] Typical refrigeration devices used in hot summer can include electric fans and air conditioners.

[0003] However, a fan can only directly circulate the surrounding hot air and is not sufficient to provide a sense of coolness to users. In addition, compared with a fan, an air conditioner can blow air at a lower temperature, so it has excellent refrigeration capacity. However, its high price makes it incomparable with an electric fan. It also consumes a large amount of electricity during operation and has side effects such as causing air-conditioning diseases and drying the indoor air.

[0004] Therefore, recently, air coolers that can play an intermediate role between fans and air conditioners and have low maintenance costs are being widely used.

[0005] An air cooler utilizes the temperature difference between water and air and the heat of vaporization. First, water is pumped out and wets a moisture absorption filter made of special non-woven fabric, or water flows from the upper part to the lower part of the moisture absorption filter. Then, if air is blown through the water film between the moisture absorption filters, the water on the moisture absorption filter will absorb the surrounding heat while evaporating, and the air whose temperature has been lowered due to the evaporation of water will be blown out, thus generating cold air.

[0006] That is, an air cooler utilizes the principle of lowering the temperature of air by the heat of vaporization of water and the temperature difference between water and air.

[0007] Compared with a conventional air conditioner that consumes a large amount of electricity by the operation of a compressor, an air cooler only consumes a small amount of electricity during the operation of a fan and a pump, so the power saving effect is remarkable.

[0008] In addition, in order to make the air cooler generate cooler air, ice cubes or ice bags are placed in a water tank storing water to cool the water, and the moisture absorption filter is wetted with cold water, so that air passes through the moisture absorption filter wetted with cold water, and then cool air is blown.

[0009] However, over time, the cold air of the ice cubes or ice bags placed in the water tank will quickly disappear, resulting in the problem that the cooling effect cannot be achieved.

[0053] Hereinafter, the present invention will be described in detail with reference to the preferred embodiments of the present invention and the accompanying drawings, and it is assumed that the same reference numerals in the drawings denote the same components.

[0054] In the detailed description of the present invention or the claims included in the invention, when any component "includes" other components, unless otherwise stated to the contrary, it should not be construed as being limited to being composed of only that component, but should be understood to further include other components.

[0055] Terms such as "upper part", "lower part", "bottom", "front", "rear", and "lower side" used in this specification are for convenience of description only and refer to the arrangement directions of the components as shown in the figures.

[0056] The air cooler 100 according to the present utility model is in a form in which the air cooler main body 101 is separated from the water tank 110. As Figure 1 shown, the air cooler 100 is constituted by fastening the air cooler main body 101 to the upper part of the water tank 110.

[0057] The air cooler 100 includes a cover 107 that covers the upper part of the air cooler main body 101.

[0058] As Figure 2 shown, the water tank 110 forms a water tank main body 111 in a box shape with an open upper part. Casters 113 are fastened to the lower part of the water tank main body 111 to facilitate the movement of the air cooler 100, and locking devices 114 are formed on both sides of the water tank main body 111. After the air cooler main body 101 is placed on the upper part of the water tank 110, the water tank 110 and the air cooler main body 101 are fastened and fixed by the locking devices 114.

[0059] The water tank 110 according to the present utility model is a device for storing water used (for wetting the moisture absorption filter 140) in the air cooler 100. In order to generate cooler cold air, ice bags and water are put into the water tank 110 together.

[0060] The cold air of the ice bags causes the temperature of the water stored in the water tank 110 to drop, and the air cooler 100 using cold water can blow out cooler air.

[0061] However, during use, the cold air of the ice bags put into the water tank 110 will quickly disappear, resulting in the problem that the cool air cannot be continuously maintained.

[0062] To solve this problem, the present utility model is configured such that the water tank main body 111 of the water tank 110 includes a heat insulation material, thereby maintaining the cold air of the ice bags put into the water tank 110 for a long time.

[0063] As Figure 2 shown, the outer surface of the water tank main body 111 of the water tank 110 is successively constituted by a synthetic resin layer 115, a heat insulation material layer 116, and a stainless steel layer 117.

[0064] The synthetic resin used as the synthetic resin layer 115 is polypropylene, polycarbonate, polyvinyl chloride, polystyrene, polyamide, etc. that are widely used in household electrical appliances.

[0065] The heat insulating material used as the heat insulating material layer 116 is glass wool, polystyrene foam, polyurethane foam, artificial mineral fiber, etc., to keep the cold air of the ice pack put into the storage part 112 of the water tank 110 and the water stored in the water tank 110 for a long time.

[0066] The stainless steel used as the stainless steel layer 117 has the effects of preventing scratches from occurring during the cleaning of the water tank 110, not corroding, preventing the generation of water scale and bacterial proliferation in the water tank 110.

[0067] As described above, the utility model is equipped with a heat insulating material layer 116 on the water tank main body 111 of the water tank 110, so that the cold air of the ice pack and water put into the water tank 110 can be kept for a long time, and the generation of water scale and bacterial proliferation can be prevented by being equipped with the stainless steel layer 117.

[0068] As Figure 2 shown, the water tank 110 configured in the above - mentioned manner is in an open - top form. As Figure 3 shown, the cover plate 120 is fastened to the open upper part.

[0069] Although not shown in the figure, a heat insulating material layer for the heat insulating material layer 116 of the water tank 110 is formed on the cover plate 120. When the cover plate 120 covers the water tank 110, it can prevent the cold air of the ice pack and water from flowing out to the outside, so that the cold air can be kept for a long time.

[0070] As Figure 3 shown, the cover plate 120 is composed of a first panel 121 and a second panel 124. The guiding protrusion (not shown) protruding from the bottom surface of the first panel 121 is inserted into the sliding groove 125 formed on the upper surface of the second panel 124, so that the first panel 121 slides along the sliding groove 125 of the second panel 124.

[0071] Moreover, at the end of the first panel 121, a through - hole 122 is formed in a perforated form of the first panel 121, and a handle 123 is formed in a protruding and extending form of the first panel 121 on the side of the first panel 121.

[0072] As Figure 4 shown, a pump 108 protrudes from the lower part of the air cooler main body 101 of the air cooler 100. When the air cooler main body 101 and the water tank 110 are combined, the pump 108 of the air cooler main body 101 is immersed in the water contained in the water tank 110, so as to extract the water stored in the water tank 110 for generating cold air.

[0073] As Figure 3As shown, in order to preserve the cold air of the water and ice packs stored in the storage part 112 of the water tank 110, the cover plate 120 is covered. A through hole 122 is formed in the cover plate 120 so that the pump 108 of the main body 101 of the air cooler can be inserted.

[0074] At this time, preferably, the size of the through hole 122 is configured to be smaller than the size of the pump 108 of the main body 101 of the air cooler, so as to minimize the gap between the cover plate 120 and the hose of the pump 108, preventing the cold air of the water and ice packs from leaking through the gap between the hose of the pump 108 and the through hole 122, thereby enabling the cold air to be preserved for a longer time.

[0075] As described above, since the size of the through hole 122 is smaller than the size of the pump 108, when the water tank 110 and the main body 101 of the air cooler are combined, the pump 108 of the main body 101 of the air cooler cannot be inserted through the through hole 122 of the cover plate 120.

[0076] Therefore, when the main body 101 of the air cooler and the water tank 110 are combined, as Figure 4 shown, in a state where the storage part 112 of the water tank 110 is opened by opening the first panel 121 of the cover plate 120, the main body 101 of the air cooler and the water tank 110 are combined.

[0077] If the water tank 110 and the main body 101 of the air cooler are combined, the locking device 114 of the water tank 110 is used to fasten the water tank 110 and the main body 101 of the air cooler. The user makes the first panel 121 slide by grasping the handle 123 protruding outward between the main body 101 of the air cooler and the water tank 110, thereby closing the storage part 112 of the opened water tank 110.

[0078] While the first panel 121 slides, the first panel 121 covers the upper part of the opened water tank 110. At this time, the pump 108 is located below the cover plate 120. While inserting the hose connected to the pump 108 into the through hole 122, the first panel 121 is closed.

[0079] Therefore, due to the heat insulation material layer 116 formed inside the wall and bottom surface of the water tank 110 and the heat insulation material layer formed on the cover plate 120, the cold air of the water and ice packs stored in the storage part 112 of the water tank 110 will be preserved for a long time, enabling cool air to be discharged from the air cooler 100 for a long time.

[0080] As Figure 4As shown, preferably, a coupling protrusion 101a protrudes from a lower edge portion of the air cooler main body 101, and a protrusion groove 126 is formed in an edge portion of the cover plate 120 in a groove shape. Thus, when the air cooler main body 101 is placed on the upper part of the water tank 110 for coupling, the coupling protrusion 101a of the air cooler main body 101 is inserted into the protrusion groove 126 of the cover plate 120, so as to ensure a gap between the air cooler main body 101 and the water tank 110 and enable the first panel 121 to slide smoothly, and the cover plate 120 is configured to be firmly fixed between the water tank 110 and the air cooler main body 101 without moving.

[0081] Generally, the air cooler 100 has a structure that sucks in external air and blows the air whose temperature has dropped due to the heat of vaporization to the outside again while passing through the moisture absorption filter 140 soaked with water.

[0082] The air cooling mechanism according to the present utility model is configured to blow cooler air by reducing the temperature of the external air sucked in from the air cooler 100.

[0083] As Figure 5 shown, the present utility model is configured to provide a metal cooling component 130 at an air inlet 106 for sucking in external air.

[0084] A filter storage opening 105 in a space shape for installing the moisture absorption filter 140 is formed on a side surface of the air cooler main body 101. The metal cooling component 130 is inserted into the filter storage opening 105, and the moisture absorption filter 140 and a filter panel 104 are inserted and fastened to the outside thereof.

[0085] The filter panel 104 is configured to filter foreign matters such as dust contained in the air sucked in through the air inlet 106. The moisture absorption filter 140 is made of a material (such as paper) that can be wetted by water pumped from the water tank 110 by a pump 108. As Figure 6 shown, it is formed in a wrinkled or twisted shape to obtain the maximum surface area.

[0086] As Figure 7 shown, the metal cooling component 130 is formed of a quadrilateral metal cooling component main body 131 made of an aluminum material with excellent thermal conductivity and ductility. Ice for freezing water is stored inside the metal cooling component main body 131.

[0087] As Figure 7 shown, the metal cooling component 130 is configured to form an openable and closable cover, so that the cover can be opened and water or a refrigerant can be put into or replaced inside the metal cooling component 130.

[0088] Inside the metal cooling component body 131 of the metal cooling component 130, support frames 132 are vertically formed at predetermined intervals. Between the metal cooling component body 131 and the support frames 132, and between the support frames 132 and the support frames 132, cooling fins 133 are formed at predetermined intervals in the horizontal direction.

[0089] And, a flow path 134 for allowing air inhaled from the outside to flow is formed between the cooling fins 133.

[0090] The cooling fins 133 can be formed in the form of a thin metal (for example, aluminum), or can also be formed as small tubes communicating with the metal cooling component body 131, and by forming the support frames 132 in the middle, it plays a role in preventing the cooling fins 133 from being easily bent or damaged when subjected to external forces.

[0091] If the air cooler 100 configured as described above is operated, while the pump 108 is operating, the water in the water tank 110 is pumped to wet the moisture absorption filter 140, and while the fan inside the air cooler 100 is operating, external air is inhaled through the suction port 106.

[0092] At this time, the external air cools the temperature of the first inhaled external air while passing through the moisture absorption filter 140, and while passing through the flow path 134 of the metal cooling component 130 for the second time, the air with further reduced temperature is discharged through the air outlet 102 on the front surface of the air cooler body 101, and the direction of the discharged cool air is adjusted by the blades 103.

[0093] If the metal cooling component 130 is used for a predetermined time, the ice stored in the metal cooling component 130 will melt. At this time, the filter panel 104 is opened and replaced with a new metal cooling component 130, so that cool air can be continuously blown.

[0094] The air cooler according to the present utility model configured as described above forms a water tank containing a heat insulating material, so that when an ice pack is put into the water tank, the cold air of the ice pack can be maintained for a long time, so that the air cooler can discharge cool air for a long time.

[0095] In addition, since the inner surface of the water tank is made of stainless steel, bacteria proliferation in the water tank can be prevented, and the attachment of water scale can be minimized.

[0096] In addition, by fastening the metal cooling component to the suction port of the air cooler, the temperature of the external air inhaled from the air cooler can be reduced, so as to blow more cool air.

[0097] The technical idea of the present utility model has been described through the above-described embodiments.

[0098] Obviously, those of ordinary skill in the art to which the present utility model pertains can make various modifications or alterations to the described embodiments based on the descriptions of the present utility model.

[0099] In addition, although not explicitly shown or described, those of ordinary skill in the art to which the present utility model pertains can make various forms of modifications including those based on the technical concept of the present utility model according to the descriptions of the present utility model, and it still falls within the scope of the claims of the present utility model.
