Abstract
An apparatus for the evacuation of warm, moist air or vapor from a dishwasher cabinet or other washing machine interior. A centrifugal fan draws the hot air and water vapor out of the washing cavity through a flue riser and discharges it into a cooling chamber with one or more cooling spray nozzles. The cooling spray nozzles spray a fine mist of cold water into the stream of heated air and vapor, and may spray at angle to the flow of the stream of heated air and vapor. As the heated air and vapor from the dishwasher and the cooling spray mix, heat is transferred from the heated air and vapor to the cold water or mist being sprayed into the air stream. This reduces the temperature of the vapors and air that was extracted from the dishwasher. As the temperature is reduced, the water vapors condense and form droplets which accumulate on the sides and bottom of the cooling flue. This reduced temperature and moisture air is then discharged to the room at an opening, which may be located slightly above the bottom of the flue cabinet, along with the condensate.
Description
- This application is a continuation of U.S. patent application Ser. No. 13/007,829, filed Jan. 17, 2011, which claims benefit of and priority to U.S. Provisional Application No. 61/295,291, filed Jan. 15, 2010, and is entitled to those filing dates for priority. The specifications, figures and complete disclosures of U.S. Provisional Application No. 61/295,291 and U.S. patent application Ser. No. 13/007,829 are incorporated herein by specific reference for all purposes.
- This invention relates to an improved method and apparatus for removing water vapor from within commercial washing machines.
- The use of automated commercial dishwashers, and other washing machines, in a variety of settings, such as restaurants, hotels, or nursing homes, among others, is widely known. A continuing problem is that such dishwashers release heat and vapor into the environment in which they operate. In situations where the operational environment is significantly colder than the operating temperatures of the machine, the vapor released by the machine will often condense on other articles in the immediate area, thereby creating the potential for mold and bacteria growth, as well as contaminated droplets falling onto food or food preparation surfaces.
- A solution to the problem has been to provide a ventilation hood above the machine that captures and removes the heated air and vapors released from the dishwasher. This is expensive and not energy efficient due to the fact the typical hood must operate at a minimum of 400 cubic feet per minute to capture the heat and vapor released by the machine. Further, as the air captured by the hood is discharged from the building and new air must be introduced into the building, the new air must be air conditioned before or as it is introduced into the building.
- One example of a dishwasher machine with a water vapor vent and recovery system is disclosed in Monsrud, et al., US 2004/0261820 (application Ser. No. 10/610,330), the complete disclosure of which is specifically incorporated herein by specific reference for all purposes. This system, however, requires a plurality of driver nozzles operating at elevated pressures to pull the vapor from the washing chamber interior. Such systems also can be expensive and not energy efficient.
- In various embodiments, the present invention comprises a system and apparatus for evacuating warm, moist air or vapor from a dishwasher cabinet or chamber, or other washing machine interior, before the doors are opened, thereby reducing the heat and vapor load applied to the room by the washer. A centrifugal fan creates a vacuum effect in the cooling flue riser, drawing the hot air and water vapor out of the washing cavity through the flue riser. The fan discharges the air and vapor mixture into the cooling flue, which comprises a cooling cabinet or space with one or more cooling spray nozzles. The nozzles may be mounted on a nozzle manifold or may be mounted on a surface of the cooling cabinet.
- The cooling spray nozzles spray a fine mist of cold water into the stream of heated air and vapor as it passes the nozzles and manifold. As the heated air and vapor from the dishwasher and the cooling spray mix, heat is transferred from the heated air and vapor to the cold water or mist being sprayed into the air stream. This reduces the temperature of the vapors and air that was extracted from the dishwasher. As the temperature is reduced, the water vapors condense and form droplets which accumulate on the sides and bottom of the cooling flue, thus reducing the heat and moisture content of the air stream. This reduced temperature and moisture air is then discharged to the room at an opening, which may be located slightly above the bottom of the flue cabinet.
- The cooling water that has had its temperature increased along with the moisture that was removed from the air stream is drained from the bottom of the device. In one embodiment, the air stream also is discharged along the bottom of the wash cavity. This raises the temperature of the air stream slightly to prevent condensation of any remaining water vapor in the air stream.
- In one exemplary embodiment, a door locking mechanism is activated at the start of the dishwashing cycle and released after the vapor removal system has had sufficient time to reduce the heat and vapor load to an acceptable level. Indicator lights or audible signals, or both, may be used to indicate to an operator when the door-interlock is engaged and the system is in operation.
- The device may comprise an adjustable timer that will allow it to be configured as needed, based on the machine and location requirements. Additional or different nozzles could be used based on a dishwasher's heat generation characteristics. The system may operate continuously regardless of the dishwasher operation, or may operate in some other relationship to the machine cycle, such as an overlapping cycle, depending on machine and location characteristics.

FIG. 1 shows a view of a system in accordance with an exemplary embodiment of the present invention. -
FIG. 2 shows an exploded view of the system ofFIG. 1 . -
FIG. 3 shows a view of the system ofFIG. 1 with nozzle spray at an angle against the flow of air. -
FIG. 4 shows a view of the system ofFIG. 1 with nozzle spray at a right angle to the flow of air. -
FIG. 5 shows a view of the system ofFIG. 1 with nozzle spray at an angle with the flow of air. - In one exemplary embodiment, as shown in
FIG. 1 , the system of the present invention evacuates warm, moist air orvapor 10 from thedishwasher cabinet 8 before the doors are opened, thereby reducing the heat and vapor load applied to the room by the dishwasher. Acentrifugal fan 20 creates a vacuum effect in thecooling flue riser 22, drawing the hot air and water vapor out of the washing cavity through theflue riser 22 and through thefan 20. Thefan 20 discharges the air and vapor mixture into thecooling flue 24, which comprises a cooling cabinet or chamber orspace 30 with one or morecooling spray nozzles 26. Thenozzles 26 may be mounted on anozzle manifold 28 or may be mounted on a surface of the cooling cabinet orchamber 30. - The cooling spray nozzles spray a fine mist of cold water into the stream of heated air and vapor as it passes the
nozzles 26 and manifold 28. The cooling spray nozzles may spray at angle to the flow of the stream of heated air and vapor. In one exemplary embodiment, the cooling spray nozzles spray at substantially right angles to the flow, as seen inFIG. 4 , while in another exemplary embodiment, the cooling spray nozzles may spray at other angles, including angles with or against the flow, as seen inFIGS. 3 and 5 . In some embodiments, the nozzles may spray at different angles at different points or locations in the flow. - As the heated air and vapor from the dishwasher and the cooling spray mix, heat is transferred from the heated air and vapor to the cold water or mist being sprayed into the air stream. This reduces the temperature of the vapors and air that was extracted from the dishwasher. As the temperature is reduced, the water vapors condense and form droplets which accumulate on the sides and bottom of the cooling flue, thus reducing the heat and moisture content of the air stream. The droplets run down the inside of the cooling flue, through the lower end 30 a of the cooling flue, into a
collection cup 32. - This reduced temperature and moisture air is discharged to the room at an opening, which may be located slightly above the bottom of the flue cabinet. The cooling water that has had its temperature increased along with the moisture that was removed from the air stream is drained from the
bottom 40 of the device or collection cup. In one embodiment, the air stream also is discharged along the bottom of thewash cavity 42. This raises the temperature of the air stream slightly to prevent condensation of any remaining water vapor in the air stream. - In one exemplary embodiment, a door locking mechanism is activated at the start of the dishwashing cycle and released after the vapor removal system has had sufficient time to reduce the heat and vapor load to an acceptable level. Indicator lights 102, 103 or audible signals, or both, may be used to indicate to an operator when the door-interlock is engaged and the system is in operation.

FIG. 2 shows a detailed view of certain additional components of an embodiment of the present invention. Theflue riser 22 is affixed at top and bottom by means of screws or bolts, andflue riser gaskets 22 a may be used to effect a tight seal. Similarly, a fan gasket 20 a may be used with the fan for the same reason. In the embodiment shown, thefan 20 is contained in atop fan housing 20 b, which also contains afan motor 20 c,timer 20 d, andrelay 20 e, supported on abracket 20 f. - The cooling spray is delivered to the
spray nozzles 26 in themanifold 28 through means known in the art, such as a fill valve andball valve assembly 28 a. - The device may comprise an adjustable timer that will allow it to be configured as needed, based on the machine and location requirements. Additional or different nozzles could be used based on a dishwasher's heat generation characteristics. The system may operate continuously regardless of the dishwasher operation, or may operate in some other relationship to the machine cycle, such as an overlapping cycle, depending on machine and location characteristics.
- For example, in one embodiment, at the end of the wash and rinse cycle the centrifugal fan operates at 45 cubic feet per minute. There are 9 cooling mist nozzles on a manifold, with an operating pressure of 25 psi water pressure. The nozzles operate for 30 seconds during the cooling cycle. Approximately 0.39 gallons of water per cycle is consumed. The nozzles may operate at ordinary, normal water pressure at most locations.
- The amount of water used per cycle depends on the water pressure and duration of the cycle. For a 30 second cycle, 0.48 gallons is consumed at 35 psi, 0.53 gallons is consumed at 45 psi, and 0.61 gallons is consumed at 55 psi. The duration of the cycle may be adjusted where conditions and desired results at a particular installation warrant.
- The device of the present invention thus may be equivalent in effect to the installation of a ventilation hood above a dishwasher. The present invention may also be used with other types of washing machines.
- Thus, it should be understood that the embodiments and examples described herein have been chosen and described in order to best illustrate the principles of the invention and its practical applications to thereby enable one of ordinary skill in the art to best utilize the invention in various embodiments and with various modifications as are suited for particular uses contemplated. Even though specific embodiments of this invention have been described, they are not to be taken as exhaustive. There are several variations that will be apparent to those skilled in the art.
