BACKGROUNDThe present invention relates to a cooling device.
During the summer, the local temperature may be uncomfortably high. Additionally, even if the local temperature is within a comfortable range, a person may be in a home, building or manufacturing plant wherein the temperature in the structure (e.g., on the shop floor) is uncomfortably high. The structure may act as an oven trapping heat during a hot summer day. Additionally, equipment (e.g., stereo, TV, printing press, etc.) within the structure may increase the temperature due to its motor or other components which generate heat.
Cooling a large enclosed space with an air conditioner may be cost prohibitive. Accordingly, employers and home owners may be reluctant to cool an entire space via air conditioning. Other devices for providing comfort to a person have been devised. For example, a mist of water may be sprayed in the air to cool the person when the water mist evaporates off of the person's skin. Fans circulate air within a room. Unfortunately, these other means of providing comfort to the person may be insufficient. For example, the fan merely blows hot air upon the person or circulates hot air within the room while the motor of the fan generates heat thereby increasing the temperature of the room. The water mist cools people only to a certain degree.
Other devices exist to cool the ambient air to a temperature below the ambient temperature. For example, a block of ice or other cooled material may be placed in front of a fan such that the fan blows ambient air over the cooled material. Heat is transferred into the cooled material to cool the ambient air and provide chilled air to the person. Unfortunately, these devices may be inefficient in transferring heat from the air to the chilled material. Accordingly, there is a need in the art for an improved device for providing chilled air to a person.
BRIEF SUMMARYThe cooling device described herein addresses the needs identified above, known in the art and disclosed below. The cooling device may have a plurality of through holes through which ambient air may flow to produce cooled or chilled air. The through holes of the cooling device may have various configurations (e.g., zig-zag, up and down, converging, diverging, etc.) to promote heat transfer of heat from the ambient air to the cooling device. Moreover, the cooling device may have a system for draining water condensate that forms on the exterior surface of the cooling device. By way of example and not limitation, the cooling device may have interconnecting vias that drain fluid from an upper through hole to a lower through hole. Also, the cooling device may have exit vias that drain the water condensate within a through hole to the exterior of the cooling device or to the bottom surface of a container of the cooling device. A tray may be located below one or more containers that are chilled to collect the dripping water condensate.
These and other features and advantages of the various embodiments disclosed herein will be better understood with respect to the following description and drawings, in which like numbers refer to like parts throughout, and in which:
The cooling device 10 includes a container 12 (see
As shown in
The cooling device 10 may additionally comprise a base 26 and a tray 28, as shown in
The tray 28 may be placed within the gap between the bottom surface 40 of the container 12 and the floor 42 of the base 26. The tray 28 may also be removed from the base 26. The tray 28 may serve as a reservoir in which water condensate on the container 12 may drip for removal at a later time. More particularly, as the fan 18 blows air through the through holes 16 of the container 12, the warmer air upon contact with the cold container 12 produces water condensate on the exterior surface of the container 12. Over a period of time, the water condensate will begin to drip downward on the exterior surface of the container 12. Most of the condensate may form on the surface of the through holes 16. Accordingly, the water condensate will tend to drip down the forward or rearward sides of the container 12. A length 44 of the tray 28 may be longer than a thickness(es) 46 of the container 12 or containers 12. When the tray 28 is disposed between the container 12 and the base 26, the front and rear edges of the tray 28 may be disposed in front of the forward side of the container and in back of the rearward side of the container 12. Accordingly, when the water condensate drips down the container 12, the water drips into the tray 28 which can be removed at a later time for removal of water. Preferably, the width 48 of the tray 28 is wider than the width 50 of the plurality of through holes 16 or the width 52 of the container 12.
The floor 42 of the base 26 may optionally have a plurality of wheels 54 which assist in inserting the tray 28 into the base 26 or removal therefrom, as shown in
The base and tray 26, 28 shown in

Through hole 16c may have two vanes 17a, b. The upper vane 17a may snake forward then rearward then forward again. The distal portion of the through hole 16c may have upper and lower surfaces 62c, 64c that project in a generally upward direction to promote water condensate to drip rearward. Through holes 16c may have two entrance apertures 24 wherein the flow path defined by both entrance apertures 24 connect near the distal portion of the through holes 16c.
Through holes 16d and 16e may snake upward and downward in a direction from the entrance aperture 24d, e and the exit aperture 22d, e. The distal portions of the through holes 16d, e may have upper and lower surfaces 62d, e and 64d, e that project generally in an upward direction. Accordingly, when water condensate reaches the distal portions of the through holes 16d, e, the water condensate will tend to drip backward against the flow of air. To prevent water from gathering and remaining within the through holes 16d, e, the valleys of the through holes may have an interconnecting via 66 which permits the water condensate to flow downward into lower through holes 16. For example, the water condensate formed in the through holes 16d may flow through the interconnecting via 66 into the through holes 16e. It is also contemplated that the valleys of the through holes 16 may have an exit via 68. The exit via 68 flows the water condensate formed in through hole 16e to the exterior surface of the container 12. The water condensate may then drip downward into the tray 28. The through holes 16f may have two curved and converging upper and lower surfaces 62f, 64f. It is also contemplated that the upper and lower surfaces 62f, 64f may be straight as shown by the dashed lines.

As discussed above, the container 12 may be filled with fluid 14 that is chilled below the ambient temperature. For example, water may be filled within the container 12 and chilled in a refrigerator. As the water is frozen, the frozen ice begins to expand within the container 12. The air passage 80a allows air within the container 12 to escape out of the container 12 such that the container 12 does not bulge outward. As the ice expands, the pressure within the container increases until the pressure overcomes the biased force of the resilient arm 86a. Air is allowed to escape out of the container 12. Conversely, as the ice melts, the air pressure within the container 12 may decrease to overcome the biased force of the resilient arm 86b. At that moment, air is allowed to reenter the container 12 through air passage 80b. To further aid in preventing the container 12 from bulging as it is frozen in a refrigerator, salt or other additives may be added into the water to decrease the freezing temperature of the water. In this manner, the refrigerator may bring the temperature of the water lower without freezing. A portion of the water may freeze (e.g., top surface). However, the entire volume of water does not freeze. Alternative fluids that are known in the art may also be used to decrease the freezing temperature.

More particularly, the frame 94 have a skeletal structure to allow the air blown by the tower fan 93 to flow through the skeletal structure. The cavities 96a, b may be sized and configured to hold containers 12a, b. The containers 12a, b may have through holes and drainage vias 66, 68 substantially similar to the through holes and drainage vias discussed above. These through holes permit the air blown through the containers 12a, b by the tower fan 93 to transfer heat from the ambient air into the containers 12a, b. These containers 12a, b may have a chillable material disposed within the containers 12a, b.
The upper supporting arms 100a, b may surround the upper portion of the tower fan 93. The upper supporting arms 100a, b may be fabricated from a unitary material and be sized configured to snuggly fit about the upper portion of the tower fan 93 such that the upper supporting arms 100a, b support the frame 94 and the containers 12a, b. Alternatively, the upper supporting arms 100a, b may be fabricated from two separate members that are removable securable to each other for mounting or removing the base 26b from the tower fan. The lower supporting arms 102a, b may snuggly fit about the lower portion of the tower fan 93. The lower supporting arms 102a, b may be resilient such that the lower supporting arms 102a, b may be spread open and wrapped about the lower portion of the tower fan 93. Alternatively, the upper and lower supporting arms 100a, b and 102a, b may be sized and configured such that the frame 94 be slid over the tower fan 93.
It is contemplated that the chillable material filled within the containers 12a, b may be a gel like substance with a very low freezing temperature. In this manner, when the container is disposed within the freezer of a typical household refrigerator, the chillable material does not freeze but remains within the liquid state but is at a low temperature.

A second pair of angled protrusions 122a, b may be located below the angled projections 112a, b, c and d. The angled protrusions 122a, b may have a generally flat upper surface 124. A tray 128 may be attached to the base 26c with the angled protrusions 122a, b. In particular, the tray 128 may have receiving cavities 130 of the tray 128. To attach the tray 128 to the base 26c, the angled protrusions 122a, b are inserted into the receiving cavities 130 of the tray 128. The receiving cavity 130 may have a nub 132 received into the indentation 126 formed in the flat upper surface 124 of the angled protrusions 122a, b.
The base 26c may comprise adjustable hooks 134a or 134b inserted into the grill of the tower fan 93, as shown in
To mount the base 26c to the tower fan 93, the outer bolt 142 is tightened onto the sliding nut 136 to fix the position of the sliding nut 136. The knurled knob 144 is disposed over the nub 146 of the sliding nut 136. Hook 134a, b is threaded onto the inner bolt 154 but not tightened. The same structure and sequence may be incorporated into the lower portion of the base 26c.
The hook 134a, b may be inserted through the grill of the tower fan 93. By turning the knurled knob 144, the orientation of the hook 134 be shifted to engage the hook onto the grill of the tower fan 93. The user may maintain the orientation of the hook 134 by resting his/her thumb on the knurled knob 144 while tightening the inner bolt 154 onto the threaded portion 152 of the hook 134.
The lower portion of the base 26c may have a block 158. The block 158 may slide vertically within a receiving cavity 160. To lock the vertical position of the block 158 in the receiving cavity 160, a set screw 162 may be tightened against the block 158.

The sleeves 164a, b provide a dedicated space within the freezer section of the refrigerator for the containers 12, 114. Additionally, the rails 170, 174 prevent the container 12, 114 from sticking onto the sleeves 164a, b. The container 12, 114 easily be removed from the sleeves 164a, b after chilling.
Referring now to
The channels 176 and side gutters 178 may be incorporated into the other containers discussed herein such as container 114 and 12a, b. Although the channels 176 are shown as downwardly sloping toward opposed sides of the container 12, it is contemplated that the channel 176 may be level or sloped to only one side. When the channel 176 is level or horizontal, the accumulation of water condensate in the channels 176 will urge the water condensate to the lower side into the side gutter 178. The channels 176 may have alternate configurations such as curved, triangular, etc.
