Disclosed herein, in certain embodiments, are vacuum-based systems, products, devices, and methods for de-odorizing, disinfecting, or cleaning articles such as clothing, shoes, toys, or dishes. A system or device can comprise a vacuum chamber comprising an housing defining an internal space having an internal pressure and an opening; a vacuum lid adapted to engage with the opening of the vacuum chamber; and a vacuum source connected to the vacuum chamber, wherein operation of the vacuum source reduces the internal pressure of the internal space of the vacuum chamber, wherein the lower internal pressure enhances the vaporization and removal of odors located on one or more articles disposed within the vacuum chamber.

A commercial dry-cleaning solvent filter apparatus is configured to filter and decontaminate a used dry-cleaning solvent in a specialized multi-level filtration container to enable environmentally-friendly reuse of the used dry-cleaning solvent in a commercial dry-cleaning machine after a novel decontamination process. The commercial dry-cleaning solvent filter apparatus incorporates multi-level gravity feed filtration chambers filled with a unique multi-metallic and multi-chemical filtration clay agent in multiple stages for comprehensive decontamination of the used dry-cleaning solvent. The filtered and decontaminated used dry-cleaning solvent is reusable and can be pumped back into a dry-cleaning solvent tank internal to the commercial dry-cleaning machine. The reuse of the dry-cleaning solvent reduces the need for frequent solvent replacements. The movement of the used dry-cleaning solvent into or out of the commercial dry-cleaning machine and the commercial dry-cleaning solvent filter apparatus is further assisted by a motorized pump mobilizing the used dry-cleaning solvent.

Provided is a washing machine including: a storage chamber configured to store carbon dioxide in a gaseous state; an additive container configured to store an additive; a mixing chamber configured to mix the carbon dioxide in the gaseous state supplied from the storage chamber with the additive supplied from the additive container and pressurize the carbon dioxide and the additive, which are mixed with each other, to generate a mixed solution in a liquid state; a washing chamber configured to wash laundry using the mixed solution supplied from the mixing chamber; and a distillation chamber configured to accommodate the mixed solution discharged from the washing chamber and vaporize the carbon dioxide from the mixed solution therein, wherein the additive lowers a vapor pressure of the mixed solution to maintain the mixed solution in a liquid state at pressures of 10 bar or less.

Disclosed herein, in certain embodiments, are vacuum-based systems, products, devices, and methods for de-odorizing, disinfecting, or cleaning articles such as clothing, shoes, toys, or dishes. A system or device can comprise a vacuum chamber comprising a housing defining an internal space having an internal pressure and an opening; a vacuum lid adapted to engage with the opening of the vacuum chamber; and a vacuum source connected to the vacuum chamber, wherein operation of the vacuum source reduces the internal pressure of the internal space of the vacuum chamber, wherein the lower internal pressure enhances the vaporization and removal of odors located on one or more articles disposed within the vacuum chamber.

Disclosed are a water purifying module self-cleaning method and a washing machine using the method. The water purifying module self-cleaning method comprises: starting a water purifying module self-cleaning program to feed water into a washing machine to reach a preset level; and repeating a heating rinsing program and a clear water replacement rinsing program in sequence until detecting that the water purifying module is clean, wherein the heating rinsing program comprises a washing water heating step, a membrane rinsing step, a standing step and a membrane air washing step. The water purifying module self-cleaning method can peel off impurities, macromolecular particles and the like from the surface of a filter system (5) of a water purifying module, thus ensuring the water purifying effect of the water purifying module and effectively prolonging the service life of the water purifying module.

A washing machine includes: a frame, a drum receiving laundry, a washing chamber including (i) a first housing defining an opening and a space into which the drum is inserted, (ii) a barrier surrounding the opening and coupled to the first housing, and (iii) a second housing surrounding a first surface of the barrier and coupled to the first housing, a storage tank receiving carbon dioxide to be supplied to the drum, a distillation chamber separating contaminants dissolved in liquid carbon dioxide, an electronic unit, and a configuration unit. The configuration unit includes a pipe moving the carbon dioxide, a first compressor and a second compressor compressing the carbon dioxide discharged after washing is completed in the drum and moving the compressed carbon dioxide into the storage tank, and an oil separator separating oil from the carbon dioxide compressed in the first compressor and the second compressor.

A densified fluid barrier cleaning system is disclosed in which a pressure vessel encases a movable basket positioned so as to cross a barrier such that one opening of the pressure vessel resides in a first environment and a second opening of the pressure vessel resides in a second environment. A tubular basket within the pressure vessel is positioned such that its central longitudinal axis is aligned with both the first and second opening of the pressure vessel. Responsive to the successful completion of a cleaning cycle, soiled articles that are introduced to the basket via the first opening from the first environment can be removed through the second opening and into the second environment thus bridging the barrier without fear of introducing contaminants from the first environment to second environment.

The present invention provides a method for cleaning fabric articles which comprises the steps of: washing the fabric articles with a cleaning solvent in a rotatable drum; rotating the drum at a high spin speed for a high spin period of time after the performance of said washing step; and heating the fabric articles for at least a period of time during the performance of said rotating step. During the heating step, at least some of the cleaning solvent is removed from the fabric articles in both liquid and vapor phases. Heating the fabric articles decreases attractive forces between the liquid phase cleaning solvent and the fabric articles, facilitating the separation and hence removal of additional quantities of the cleaning solvent from the fabric articles.
