The present invention is part of US Patent Application No. 10/775915, filed February 9, 2004.

FIELD OF THE INVENTION The present invention generally relates to portable air conditioning units for golf carts. In particular, the air conditioning unit fans the air over a surface area in direct contact with a liquid that is much cooler than the ambient air so that the surface area temperature approaches the temperature of the liquid by ingesting the ambient air. Cooling by cooling the ambient air to a scent. The unit also draws outside air that warms as it passes through the heated coils to heat the ambient air. The unit also serves as a liquid storage container that can be used to store beverages or other consumable beverages.

Outdoor golf carts are also used at extreme temperatures. For example, golfers want to maintain a comfortable environment while driving around a golf course when playing in hot summer or cold winter. One way to solve this problem is to install a portable air conditioner on the golf cart itself. However, air conditioning units are very expensive, bulky, contain elements that may be harmful to the environment, and may require an AC external power source for operation. Since most golf carts run on battery power, it is very difficult to run an air conditioning unit unless it is very small or cannot run on its own battery.

One of the major concerns of many golf courses is to avoid infecting people with potentially harmful bacteria that may breed in standing water on the courses. Ponds and streams in golf courses are used to water the pools on the course. In some golf courses, customers who have come in contact with the contaminated water on the course have become ill and die. It is particularly desirable to prevent golf course staff and customers from contaminating the water supply, especially when faced with water that may be standing for a long time in hot weather.

The present invention solves these problems by providing a portable air condition unit that cools and heats ambient air when using a golf cart. The invention allows the use of a portable device comprising a reservoir for cooled liquid or ice that is isolated from human contact by a locking mechanism and is accessible only to authorized persons. The reservoir is insulated except at the bottom thereof, which provides a heat sink that provides not only the bottom area of the reservoir but also the area underneath the reservoir that serves as the air duct. It also serves as the top. The heat exchange system is substantially hollow, but may include a series of fins in contact with the reservoir. The heat exchange system is designed to maximize air exposure to the exposed surface area of the reservoir since only the air to be cooled is in direct contact with the exposed surface of the reservoir. In general, the heat exchange system should be located at the bottom of the unit so that heat transfer between the outside air and the bottom area of the reservoir can occur even if there is a very low level of cooled liquid in the reservoir. This would take advantage of the principle that the coldest liquid will always remain at the bottom of the container while in a given environment, resulting in a much more efficient cooling system.

If the reservoir is filled with cold liquid or ice, the exposed surface area of the reservoir will be cooled to the temperature of the contents of the reservoir. The heat exchange system is connected at one end to an air intake chamber and at the other to an air exhaust chamber. Hot air is drawn into the intake chamber from a battery-powered variable-speed motorized fan that creates a vacuum. The fan then dehumidify by pushing hot air through the heat exchange system to make direct contact with the exposed surface area of the reservoir and pins protruding perpendicular to the bottom surface of the reservoir within the heat exchange system; Is cooled. The pins provide resistance and change the direction of the air to create turbulence. In addition, the coolness from the exposed surface area is transferred down through the fins which provide a further cooled surface area, which further contacts and cools the air. Turbulence greatly improves the thermal conductive capacity of the system so that heat transfer occurs at a high efficiency rate and maximizes the time that the temperature of the exposed surface of the reservoir remains cold. The cooled air can then be propagated into an exhaust chamber that is thrust into the external environment, and can be used to direct an individual or generally to cool the surrounding area.

Over time the cold fluid comes into contact with the surface of a heat exchanger that is exposed to the interior of a reservoir or container, finite number as the velocity of the fluid is zero and the distance from the surface increases. Where it changes rapidly, there is a narrow area adjacent to the surface of the heat exchanger. This is known as the boundary layer. The velocity of the fluid is zero due to several factors ranging from molecular attraction to frictional forces to surface tension. If a boundary layer is formed, the surface area of the fins may prevent efficient thermal conductivity between the inner reservoir to the surface area of the fins. This lack of conductivity is due to the insulation of the layers and the boundary layer is created from the fluid immediately adjacent to the exposed surface of the heat exchanger.

If the ambient air temperature is sufficiently cold, the unit also serves to heat the outside air by drawing cold air into the unit and passing it through a series of heated coils before venting it back to the surrounding environment. The unit operates in the same way as the hair dryer heating the ambient air. In general, a user can select a heating or cooling process by means of a switch that redirects air through a given path, depending on whether heating or cooling is desired. The air conditioning unit itself may be set to switch only when more than one person is seated in the golf cart. This is accomplished by using a seat switch to detect the presence of a person in the driver's or passenger seat of the cart.

The reservoir may also include additional features such as a holding area for keeping beer and soda cans cold and an aroma cartridge for fragrance of the surrounding air. The reservoir may also be removed from the unit so that its contents can be stored in a refrigerated environment. This allows multiple reservoirs to be used in series, thereby increasing the time for which cool air can be produced. Another feature of the device is that airflow can be directed by an extendable hose embedded in the exhaust chamber of the unit. The overall outer surface of the unit must be heavily insulated to prevent unwanted heat from contacting the contents of the reservoir.

In addition, the invention claimed below for a portable air conditioner may be utilized in other applications, such as automobiles, boats, RVs, trucks, patio furniture, stadium seats or any similar application. It is obvious to those skilled in the art.

DETAILED DESCRIPTION The detailed description of the present invention described below in conjunction with the accompanying drawings should not be construed as being limited to the invention by the examples shown and described, for the reason that those skilled in the art to which the invention belongs belongs within the scope of the appended claims Other forms can be devised.

According to one of several examples that serve as background for understanding the invention, FIG. 1 shows a portable air conditioner 100 that includes a base unit 110 and a removable beverage container 120. The container 120 is for storing a liquid or solid whose temperature is substantially cooler than the air temperature outside of the air conditioner 100. The contents of the container 120, which may include cold beverages such as ice water, may be accessed through spouts 130. The handle 125 is intended to be easy to carry. The container 120 is fixed in the base unit 110 shown in FIG. The outer portion of the base unit 110 includes an intake valve 140 that takes air from the outside of the air conditioner 100 for processing in the unit 110 and is discharged out of the air nozzle 155. The air nozzle 155 is connected to the expandable hose 150 so that the air discharged from the nozzle 155 can be directed to a given place.

In FIG. 2, the container 120 is shown with its handle 125 removed from the fully extended base unit 100. The container 120 comprises a highly thermally conductive non-toxic material, such as aluminum, that is thickly insulated on all sides 165 except for the bottom 160 of the container. The lower portion 160 is in direct contact with the base unit 110 when it is exposed and fixed. The main purpose of the bottom 160 is to obtain the same temperature of the liquid or solid inside the container 120 and subsequently to maintain it for as long as possible, and to maintain constant contact with the surface area 175 by maintaining the surface area 175. ) Is to cool to the temperature of the liquid 200 inside the reservoir 220. The surface area 175 of the lower portion 160 is used to cool any air that comes into contact with the surface area 175. Since the container 120 is removable, it is possible to fill the container 120 with a given liquid and store it in a refrigerated environment for later use. The container 120 may also be filled with a liquid and stored in a freezer to freeze the entire contents of the container 120. The typical size of the container 120 may contain between 1/2 gallon and 2 gallons of liquid.

3 shows a cross-sectional view of an air conditioner 100 with a container 120 fixed in the base unit 110. As shown, the cooled liquid 200 fills approximately 3/4 of the top of the reservoir 220. The container 120 is surrounded on all sides by an insulation 210 to maximize the time that the cooled liquid 200 maintains its original temperature.

Air from outside of the air conditioner 100 is sucked into the intake chamber 140 by a high speed electric motor 255 that can be operated by a battery 260. Alternative embodiments of the present invention may include an AC / DC power supply. However, it can be seen that the AC / DC power supply limits the portability of the air conditioner 100. The motor 255 rotates the rotating fan 250 in a manner that creates an airflow 230 that draws hotter air from the outside of the air conditioner 100. It is desirable to minimize the volume of the intake chamber 140 while maximizing the amount of airflow 230. The air flow 230 follows a general direction from the intake chamber 140 through the fan 250 and into the central chamber 240 as shown by the arrows. It is desirable to maximize the volume of the chamber 240 using the fins 245 (FIG. 3A) to create turbulent flow of air. By creating an environment in which the fins 245 are in direct contact with the bottom surface region 175 and the air molecules are in contact with the conducting surface region 175, the temperature of the airflow 230 is minimized. Thus, the temperature of the liquid 200 inside the storage container 220 may be approached. Since the chamber 240 is in direct contact with the lower portion 160 (FIG. 3A) of the container 120, the lower portion 160 has a surface area (even if a minimum amount of liquid 200 remains in the reservoir 220). 175) can continue to cool for a long time.

As shown in FIG. 3A, one embodiment of the removable container 120 is a cooled surface region 160 to maximize the time that airflow 230 may be in direct contact with the cooled surface region 160. It shows how this can be arranged. As can be readily seen, the lower surface area 175 of the reservoir 220 is composed of a series of vertically disposed pins 245 projecting perpendicular to the lower surface 175. The fins 245 are made of an efficient thermally conductive material such as aluminum or copper. Note that the pins 245 need not be positioned exactly perpendicular to the bottom surface 175. As described above, because the pins 245 are directly connected to the bottom surface 175 of the reservoir 220, the temperature of the surface regions of all the fins 245 may be the lower, which may be the temperature of the contents of the reservoir 220. Will fall to the temperature of face 175. As the airflow 230 passes between the fins 245, it has the maximum amount of cooled surface area that the airflow 230 is in contact with, thereby minimizing the temperature of the airflow 230. The airflow 230 also bounces back and forth between each of the fins 245, thereby creating the turbulence 240 as shown in FIG. 3. In an alternative embodiment, the fins 245 are arranged in a maze-like formation such that the airflow 230 can reverse its direction of travel several times, thereby creating larger turbulence and Airflow 230 may be enabled to maximize the surface area of the fins 245 in contact.

Alternatively, in FIG. 3B, the fins 245 may form a continuous thermally conductive surface with fins 246 extending within the reservoir 220. At some point during the heat exchange process, a thin layer of ice may be formed on the fins 245 that may reduce the efficiency of the heat exchange. This can occur in the same way that ice can accumulate in a refrigerator-freezer that electrically cools the thermally conductive metal surface as the main source for heat exchange. It was recognized that adding pins 246 directly connected to the pins 245 can result in substantial reduction, in many cases complete removal of the boundary layer. As a result, more efficient heat transfer can occur, allowing the coldest possible temperature on the surface area of the fins 245 to be maintained for the longest time possible.

In an alternative embodiment that also serves to solve the problem of boundary layer formation, FIG. 3C provides an alternative approach when attempting to completely freeze the contents of the reservoir. The lower surface 175 includes a drainage pipe 222. The tube 222 has an opening 224 extending in the reservoir 220 and a cap 223 on the outer end of the tube 222. When the embodiment is used as a reservoir 220 containing frozen contents, the tube 222 is used to drain excess liquid that can melt from the frozen contents over time. Through experiments, it has been found that the boundary layer is frequently formed on the pins 245 when only the frozen contents in the storage container 220 are used. However, if excess water is drained from the reservoir 220, the boundary layer appears less frequently on the fins 245 and will not appear many times.

In another embodiment shown in FIG. 3D, an agitator 251 is included in the reservoir 220. The stirrer includes a set of blades 252 fixed perpendicular to the rod 253, so that when the rod 253 is rotated in a circular manner, the blade 252 may The contents will be mixed. This may be necessary if some of the frozen contents of the reservoir 220 are collected in one portion of the reservoir 220. By mixing the contents of the reservoir 220, the lower surface area 175 will be considered to maintain the temperature of the contents of the reservoir 220 for the longest time. It is understood that the stirrer 251 can be operated manually by an external crank or electrically by a motor. This embodiment may be combined with the embodiments of FIG. 3B or 3C.

Referring again to FIG. 3, upon exiting the chamber 240, the airflow is now cooled substantially below the ambient air temperature and proceeds toward the exhaust chamber 290. In a preferred embodiment, the airflow 230 is moved through an extensible hose 280 that can extend like an accordion 300 as shown in FIG. 4 to direct the airflow 230 in any direction desired by the individual. And to the point.

5 and 6 show a more detailed view of the expandable hose 280 connected to the exhaust valve 290. The hose 280 has one end attached to a catch 270 and the other end attached to an exhaust valve 290. As shown in FIG. 5, when the hose 280 is in a fully retracted position, the combination of the three elements is in an isolated exhaust guide 310 such that the hose 280 is shown in FIG. 6. When fully extended as shown, the catch 270 moves upward in the guide 310 until the catch 270 reaches the top of the guide 310, so that the valve 290 can You can also head to a place.

7-16 show an alternative embodiment of a portable air conditioner with additional components that allow both cooled air and heated air to be discharged to the environment. As shown in FIG. 16, the unit is used to cool or heat a golf cart or other mobile outdoor vehicle.

As shown in FIGS. 7-9, the seat switch 400 is shown. The switch 400 is fixed to a passenger seat or driver's seat 435 in a golf cart, so that the switch 400 operates the air conditioner 100 when a person is seated on a seat 435. As shown in FIG. 8, the switch 400 is in the "open" position. The bottom of the cushion of the golf cart seat 430 is in direct contact with the top contact 420 by a flexible panel 450. The flexible panel 450 is secured to the golf cart 445 and holds the switch 400 in the open position until a person is seated on the cushion 431. When a person is seated on the cushion 431, the flexible panel 450 is lowered onto the lower contact 440 by the top 410 of the flexible panel 450. When the contacts 420 and 440 meet, the switch 400 is changed to the “closed” position as shown in FIG. 9, thereby opening the air conditioner 100 by the wires 460 as shown in FIG. 7. Will be turned on.

As shown in FIG. 10, the air conditioner 100 generally shows an alternative embodiment with a container 120 fixed in the base unit 110. The modified air conditioner 100 utilizes a locking mechanism 505 that can be secured by a standard key 500. The locking mechanism 505 not only secures the entire container 120 in the base unit 110, but also secures the top of the compartment 515 in the locked position, thereby providing a compartment as shown in FIG. 11C. Anyone not authorized to access the compartment 515 will not be able to access the contents in the compartment 515. When unlocked, the container 120 may be removed from the base unit 110 as shown in FIG. 11A. The modified base unit shown in FIG. 11B displays a locking mechanism 505 and a recessed chamber 240. The unit of FIG. 11C shows the drink container 520 stored in an insulated region between the top of the compartment 515 and below the hinged lid 510. Drink container 520 may not be contaminated by the contents of compartment 515 underlying it.

An alternative embodiment of the air container 100 maintains the basic operation of drawing ambient air into the intake valve 140 and venting air out of the hose 150. However, in a modified golf cart embodiment, the user may choose to use an air conditioner to cool or heat the ambient air. The user may also vary the speed of the motor 255 driving the fan 250 using the controller 560 as shown in FIGS. 12A and 12B. As shown in FIGS. 12A-12E, the switch 550 may be manually moved from left to right depending on whether heating or cooling is desired. 12C-12E provide detailed cross-sectional views of the exhaust chamber 290 showing how the switch 550 operates. The switch 550 includes two hollow cylinder portions 610, 615. Within the cylinder 610, the heating element 611 is fixed and may be switched on from the control unit 560.

12C shows switch 550 operating in a “heat” mode. As airflow 230 enters exhaust chamber 290 from inner chamber 240, air enters cylinder 610 and traverses heating element 611, similar in shape to a standard hair dryer. When the airflow 230 passes through the cylinder 610, it reaches a much higher temperature than when it enters the cylinder 610. Sample heating element 611 is shown in more detail in FIG. 12E.

12D shows the switch 550 operating in the "cool" mode. As airflow 230 enters exhaust chamber 290 from inner chamber 240, air enters cylinder 615 and passes directly through hose 150 without being obstructed.

Alternative embodiments also include a noise reduction mechanism 700 as shown in FIGS. 13A-13D. Front and side views showing cross-sectional views of a damping muffler 700 are shown in FIGS. 13A and 13B, respectively. As can be seen in FIGS. 13A and 13B, ambient air sucked into the intake valve 140 enters the muffler 700. The muffler 700 comprises a faceplate having a plurality of curved or bends as part of the surface area of the molded material and having a circular opening 711 as shown in FIG. 13D; 710). The circular opening 711 is directly attached to the fan 250. When the fan 250 is operated, the noise generated by the motor 255 can sometimes be loud. In the normal case where the muffler 700 is not present, the fan noise can be passed back through the intake valve 140 in a direct path. In this embodiment, when the fan 250 is coupled to the muffler 700, the sound waves are muffled because there is no direct path to be passed back through the intake valve 140. As the sound waves are delivered through the air in the muffler 700, not only meets the incident air that disturbs the sound pulses, but also reflected and refracted back and forth through the muffler 700, so that the sound is shown in FIG. 13C. It is further suppressed to exit the intake valve 140.

Additionally, alternative embodiments include a directional spout 840 attached to the hose 280 as shown in FIG. 14A. The spout 840 includes two main air paths. The first air path 841 is where most of the air discharged from the exhaust chamber 290 collects. The second air path 842 includes an opening 830 used to secure the aroma cartridge 800. The aroma cartridge 800 includes a fragrance card 805 fixedly fastened in the cartridge 800. The cartridge also includes a variable fragrance control 810 that changes the size of the opening in the cartridge 800 to spread the fragrant air into the surrounding area as shown in FIGS. 14B and 14C. The spout 840 includes several holes 820 that discharge unscented air. As shown in FIG. 14D, the air exiting the exhaust chamber 290 may follow one of two paths. Air passing through path 841 maintains unscented air, while air passing through path 842 is fragrant.

FIG. 15 shows an overall air conditioning system including a semi-rigid rod 850 used to hold the spout 840 in a fixed configuration. 16 and 17 show the system when used in conjunction with golf cart 900.
