Description

STEAM CLEANING APPARATUS

FIELD AND BACKGROUND OF THE INVENTION

The present invention relates to cleaning apparatus for cleaning with the

aid of steam and, in. particular, it concerns utilizing steam for external and

internal cleaning of buildings, cars, industrial machinery and the like as well as

utilizing water, and/or a detergent, and/or a vacuum and/or collecting cleaning

fluids and materials, A large number of cleaning apparatus using various types of steam have

been proposed through the years, for the purpose of aiding in removing grease,

dirt, grime and the like from a variety of items, such as buildings, gates,

engines, machinery and so forth.

In a number of applications, such as in the cleaning of large objects such

as tucks and buildings or series of trucks and buildings, it is considered

preferable to perform a continuous cleaning process without having recourse to

stopping due to loss of steam pressure.

By contrast, loss of steam pressure, as by attempting to clean large or

multiple objects, does nothing to prevent interrupting or disrupting the work of

workers and often leads to frustration, increased costs and significant idle time

until steam pressure builds back up to the desired pressure.

Recent advances in technology have attempted to provide a solution to

any of the above defficiencies, the operation of an apparatus with steam also has many advantages. For example, the user needs to address the problem of

calcification and de-scaling of nozzles and pipes.

Such systems generally suffer from at least two disadvantages. First, the

drop in steam pressure requires halting and/or stopping the cleaning process on

a regular, rather than being able to clean large objects and surfaces and/or a

large number of objects. Second, since the cleaning systems use water and

steam flowing through various types of openings and/or nozzles, calcification

and scaling which builds up in pipes, tubes nozzles and openings will be

de lrimental to the efficiency of any such cleaning system. Clearly, a more useful solution would enable the cleaning apparatus to

be capable of cleaning large and/or numerous objects without loss of steam

pressure. In addition, such a solution would enable the user to perform

cleaning with reduced scaling and calcification of the apparatus.

There is thus a widely recognized need for, and it would be highly

advantageous to have, a steam cleaning apparatus which can readily provide

large quantities of steam under a substantially constant pressure, which would

facilitate cleaning large and/or numerous objects without stoppages, and which

would significantly decrease the need of decalcification and/or de-scaling of the

components of the apparatus. There is a further need for a steam cleaning apparatus, which can be

retrofitted to existing cleaning apparatus with a simple set of modifications to

the existing cleaning apparatus and which can readily provide large quantities

of steam under a substantially constant pressure, which would facilitate cleaning large and/or numerous objects without stoppages, and which would

significantly decrease the need of decalcification and/or de-scaling of the

components of the apparatus.

SUMMARY OF THE INVENTION According to the present invention there is provided a steam cleaning

apparatus for cleaning a variety of objects and machinery, comprising: (a) a

heating vessel including a first heating element, a heating base including a

second heating element, which the heating base is thermally attached to the

heating vessel for complimentary heating between the heating vessel and the

heating base, and (c) a fluid displacement unit for displacing any fluid and/or

water throughout the apparatus.

According to one embodiment according to the present invention the

steam cleaning apparatus as in claim 1 further comprises a detergent container

COL' readily providing a detergent to any fluid and/or steam in the steam cleaning

apparatus.

According to a further embodiment according to the present invention

the steam cleaning apparatus further comprises a vacuum cleaner element for

collecting any dirt and/or fluid during and/or subsequent to cleaning.

According to a still further embodiment according to the present

invention the steam cleaning apparatus further comprises an extendable arm

attached to the fluid displacement unit for extended reach and readily

facilitating application of steam to surfaces requiring cleaning.

According to further features in preferred embodiments of the invention described below, the extendable arm further comprises a first nozzle for

controlling the quantity and/or pattern and/or pressure of fluid and steam

exiting the extendable arm.

According to yet a further embodiment according to the present

invention the steam cleaning apparatus further comprises a control panel for

readily controlling a parameter selected from the group consisting of: a water

temperature, a steam temperature, a flow rate of fluid, a pressure of steam, a

water to detergent ratio, a water to steam ration, a nozzle size, a quantity of

nozzles and a level of fluid. According to further features in preferred embodiments of the invention

described below, the control panel includes a digital display.

According to a further embodiment according to the present invention

the steam cleainϊng apparatus further comprises a check valve connecting

between the heating vessel and the heating base. According to former features in preferred embodiments of the invention

described below, the check valve provides only one way flow of water into the

heating vessel while substantially preventing flow of water from the heating

vessel back into the heating base.

According to a still further embodiment according to the present

invention the steam cleaning apparatus further comprises a hollow element for

controlling flow of hot and/or boiling water from the heating vessel exiting

through the hollow element and wherein the hollow element is situated in an

aperture formed in the side of the heating vessel. According to further features in preferred embodiments of the invention

described below, the hollow element is formed or includes a coating of Teflon®

such that scaling and/or calcification is substantially prevented in and around

the hollow element.

Hereinafter, the term "steam" includes, but is not limited to, any water or

fluid in the form of an invisible gas or vapor, any water or fluid changed to this

form by boiling, extensively used for cleaning purposes, any mist formed when

the gas or vapor from boiling water or fluid condenses in the air, any exhalation

o f a vapor or mist.

Hereinafter, the term "scale" includes, but is not limited to, any

deposition of lime or insoluble salts of calcium and magnesium. '

The present invention successfully addresses the shortcomings of the

presently known configurations by providing a steam cleaning apparatus, which

overcomes the various disadvantages of presently known apparatus.

The present invention discloses a novel steam cleaning apparatus, which

includes a vessel with at least one heating element, which are designed to

readily provide steam, under pressure, for extended time periods and for

preventing scale and calcification.
