The present disclosure generally relates to vacuums. More particularly, but not exclusively, the present disclosure relates to wet/dry vacuum system with switchable collection chambers.
Conventional portable wet/dry vacuum systems are typically limited in the amount of water or liquid they can collect at one time before the liquid must be manually released from a water collection chamber. The removal of liquid will typically involve the detachment of the water collection chamber from an overall vacuum assembly or vacuum motor assembly. In some instances, a water collection chamber may have an outlet port for the slow release of water via an outlet hose that must be placed near a drain such as a shower or water tub drain, particularly when working in a multistory building such as a condominium or office building. Otherwise water will likely be released in locations that may not be intended.
In other instances contexts where a dehumidifier has a water collection chamber, the water collection chamber could include a pump to usher out the water collected in the water collection chamber of the dehumidifier. Again, a hose is typically connected to an outlet from the water collection chamber and the hose must be placed near a drain of a shower or tub to avoid having water released in locations unintended. In some instances, more than one pump is used to pump out water from the water collection chamber which can cause further issues such as triggering circuit breakers to switch off when a circuit is overloaded due to the use of multiple pumps and other electronic loads such as the motor of the vacuum itself.
All of the subject matter discussed in the Background section is not necessarily prior art and should not be assumed to be prior art merely as a result of its discussion in the Background section. Along these lines, any recognition of problems in the prior art discussed in the Background section or associated with such subject matter should not be treated as prior art unless expressly stated to be prior art. Instead, the discussion of any subject matter in the Background section should be treated as part of the inventor's approach to the particular problem, which, in and of itself, may also be inventive.

Further see
In some embodiments, the water collection chamber 120 further includes a flapper valve 122 at a bottom portion of the water collection chamber 120. In some embodiments, the flapper valve can be configured and constructed to maintain one chamber portion (e.g., 121a) closed while it collects a predetermined amount of water in such chamber and then automatically open due to gravity of the water and water flow coming into the chamber portion 121a. In some embodiments, the flapper valve 122 can be spring loaded with a predetermined amount of tension. In some embodiments with further reference to
In some embodiments, the vacuum apparatus 100 further includes a filter basket 108 configured and constructed between the vacuum chamber assembly 104 and the intake chamber 110. The filter basket 108 is used to filter out solid debris that may be sucked in with the air and water through the inlet port 102. Alternatively, instead of a filter basket as shown, a cloth-based or mesh-based filter can be used to filter out the solid debris within contemplation of the embodiments. The filter basket 108 can be porous and yet have a fine enough mesh or grid to capture most solid debris. In some embodiments, both a filter basket and a separate cloth or mesh-based filter can be used. In any instance, any or all of the filter basket or cloth or mesh-based filter can be disposable and/or removable.
In some embodiments, the intake chamber 110 further includes at least one or more fan guards 111 for mitigating water or other debris from entering the motor.

In the absence of any specific clarification related to its express use in a particular context, where the terms “substantial” or “about” in any grammatical form are used as modifiers in the present disclosure and any appended claims (e.g., to modify a structure, a dimension, a measurement, or some other characteristic), it is understood that the characteristic may vary by up to 30 percent. For example, a small cell networking device may be described as being mounted “substantially vertical,” In these cases, a device that is mounted exactly vertical is mounted along a “Y” axis and a “X” axis that is normal (i.e., 90 degrees or at right angle) to a plane or line formed by a “Z” axis. Different from the exact precision of the term, “vertical,” and the use of “substantially” or “about” to modify the characteristic permits a variance of the particular characteristic by up to 30 percent.
The terms “include” and “comprise” as well as derivatives thereof, in all of their syntactic contexts, are to be construed without limitation in an open, inclusive sense, (e.g., “including, but not limited to”). The term “or,” is inclusive, meaning and/or. The phrases “associated with” and “associated therewith,” as well as derivatives thereof, can be understood as meaning to include, be included within, interconnect with, contain, be contained within, connect to or with, couple to or with, be communicable with, cooperate with, interleave, juxtapose, be proximate to, be bound to or with, have, have a property of, or the like.
Unless the context requires otherwise, throughout the specification and claims which follow, the word “comprise” and variations thereof, such as, “comprises” and “comprising,” are to be construed in an open, inclusive sense, e.g., “including, but not limited to.”
Reference throughout this specification to “one embodiment” or “an embodiment” or “some embodiments” and variations thereof mean that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of the phrases “in one embodiment” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the content and context clearly dictates otherwise. It should also be noted that the conjunctive terms, “and” and “or” are generally employed in the broadest sense to include “and/or” unless the content and context clearly dictates inclusivity or exclusivity as the case may be. In addition, the composition of “and” and “or” when recited herein as “and/or” is intended to encompass an embodiment that includes all of the associated items or ideas and one or more other alternative embodiments that include fewer than all of the associated items or idea.
In the present disclosure, conjunctive lists make use of a comma, which may be known as an Oxford comma, a Harvard comma, a serial comma, or another like term. Such lists are intended to connect words, clauses or sentences such that the thing following the comma is also included in the list.
As the context may require in this disclosure, except as the context may dictate otherwise, the singular shall mean the plural and vice versa. All pronouns shall mean and include the person, entity, firm or corporation to which they relate. Also, the masculine shall mean the feminine and vice versa.
When so arranged as described herein, each computing device may be transformed from a generic and unspecific computing device to a combination device comprising hardware and software configured for a specific and particular purpose. When so arranged as described herein, to the extent that any of the inventive concepts described herein are found by a body of competent adjudication to be subsumed in an abstract idea, the ordered combination of elements and limitations are expressly presented to provide a requisite inventive concept by transforming the abstract idea into a tangible and concrete practical application of that abstract idea.
The headings and Abstract of the Disclosure provided herein are for convenience only and do not limit or interpret the scope or meaning of the embodiments. The various embodiments described above can be combined to provide further embodiments. Aspects of the embodiments can be modified, if necessary to employ concepts of the various patents, application and publications to provide further embodiments.
