Description
Technical Field
The present invention relates to a washing apparatus, and particularly to a microbubble agent cartridge assembly and a washing apparatus having the same.
Background
Micro-bubbles (micro-bubbles) generally refer to micro-bubbles having a diameter of fifty micrometers (μm) or less when the bubbles occur. Micro-bubbles may also be referred to as micro-/nano-bubbles, micro-bubbles or nano-bubbles depending on their diameter range. Microbubbles have a relatively long residence time in a liquid because of their small buoyancy in the liquid. Moreover, the microbubbles will shrink in the liquid until finally breaking, generating smaller nanobubbles. In this process, the rise speed of the bubbles becomes slow because they become small, resulting in high melting efficiency. When the microbubbles are broken, high pressure and high temperature heat are locally generated, and thus foreign substances such as organic substances floating in the liquid or adhering to the object can be destroyed. In addition, the contraction process of the microbubbles is accompanied by an increase in negative charge, and the peak state of the negative charge is usually when the diameter of the microbubbles is 1 to 30 μm, so that positively charged foreign substances floating in the liquid are easily adsorbed. The result is that the foreign matter is adsorbed by the microbubbles after it is destroyed by the breaking of the microbubbles, and then slowly floats to the liquid surface. These properties provide the microbubbles with a strong cleaning and purifying power. At present, microbubbles have been widely used in washing apparatuses such as washing machines.
For example, chinese published patent application CN108602030A discloses a washing machine having a water injection device. The water injection device includes an electromagnetic water supply valve, a water injection cartridge, and a fine bubble generator disposed between the electromagnetic water supply valve and the water injection cartridge. The fine bubble generator is a cylindrical shape having a flange, and includes a flow path member and an impact portion provided in the flow path member, the impact portion locally reducing a cross-sectional area of a flow path in the flow path member so that fine bubbles are generated in a liquid passing through the flow path. After the electromagnetic water supply valve is opened, the water flow from the main water pipe is rapidly depressurized while flowing through such a fine bubble generator, so that air in the water flow is precipitated to generate micro bubbles in the water, and then the micro bubble water flows into the water injection box and is mixed with detergent or softener, etc. in the water injection box to enter the washing drum for washing the laundry. However, such a fine bubble generator can generate fine bubbles only by very limited air carried in the liquid flowing therethrough, and therefore, the fine bubble generator cannot supply a sufficient amount of fine bubble water of the micro bubbles to the water injection cartridge, thereby affecting the dissolution of the detergent or softener, resulting in poor washing effect, and the remaining detergent may cause a risk to the health of the user.
Accordingly, there is a need in the art for a new solution to the above problems.
Disclosure of Invention
In order to solve the above-mentioned problems in the prior art, i.e. to solve the technical problem of low micro-bubble generation rate of the existing water injection box, the invention provides a micro-bubble treatment agent box component, the microbubble agent cartridge assembly includes a housing and a agent cartridge accommodated in the housing, the shell is provided with a micro-bubble water inlet pipe part, a tapered channel part with the diameter reduced, an air inlet channel and a micro-bubble bubbler, at least one stage of tapered channel with the diameter being reduced is arranged in the tapered channel part with the diameter being reduced along the water flow direction, and an injection hole is provided on a downstream end of the diameter-diminishing tapered channel portion positioned such that a water flow entering the micro-bubble water inlet pipe portion will be subjected to pressurization within the at least one stage of diameter-diminishing tapered channel and expandably ejected from the injection hole to generate a negative pressure in the vicinity of the injection hole; the air inlet passage is positioned close to the nozzle hole so that external air is sucked through the air inlet passage by the negative pressure and mixed with the ejected water flow to form bubble water, and the bubble water flows through the micro bubble bubbler to form micro bubble water and is ejected into the treatment agent box.
In a preferred embodiment of the microbubble treatment agent cartridge assembly, the diameter-reduced tapered passage portion and the microbubble bubbler are disposed in the microbubble water inlet pipe portion.
In a preferred embodiment of the microbubble treatment agent cartridge assembly, the diameter-reduced tapered passage portion and the microbubble bubbler are disposed between the microbubble water inlet pipe portion and the treatment agent cartridge.
In a preferred embodiment of the microbubble treatment agent cartridge assembly, a spray chamber is further provided on the housing, and the spray chamber is located above the treatment agent cartridge to spray the microbubble water into the treatment agent cartridge.
In a preferred embodiment of the microbubble treatment agent cartridge assembly, the microbubble bubbler is disposed in the shower chamber.
In a preferred embodiment of the microbubble treatment agent cartridge assembly, the housing is further provided with at least one non-microbubble water inlet pipe part for providing non-microbubble water to the treatment agent cartridge.
In a preferred embodiment of the microbubble agent cartridge assembly, a turbulent flow portion is provided on an inner wall of the tapered passage portion with a reduced diameter.

As can be appreciated by those skilled in the art, in the technical solution of the present invention, the microbubble agent cartridge assembly includes a housing and a agent cartridge accommodated in the housing. The shell is provided with a micro-bubble water inlet pipe part, a tapered channel part with the diameter reduced, an air inlet channel and a micro-bubble bubbler. At least one stage of tapered channel with the diameter being reduced is arranged in the tapered channel part with the diameter being reduced along the water flow direction, and a spray hole is arranged at the downstream end of the tapered channel part with the diameter being reduced. The diameter-reduced tapered passage portion is positioned such that water flow entering the microbubble water inlet pipe portion will flow into the at least one stage of diameter-reduced tapered passage and be subjected to pressurization therein, and then be ejected from the nozzle hole with rapid expansion and generate negative pressure in the vicinity of the nozzle hole. The air inlet channel is positioned close to the spray hole, so that outside air is sucked through the air inlet channel under the action of negative pressure and is mixed with water flow sprayed out of the spray hole to form bubble water. The bubble water then flows through the microbubble bubbler to become microbubble water that is then sprayed into the treatment agent box to dissolve and mix with one or more treatment agents located within the treatment agent box. Therefore, the microbubble agent cartridge assembly of the present invention significantly improves the efficiency of microbubble generation by the combined action of the tapered passage part with the reduced diameter, the air intake passage and the microbubble bubbler, and further can more effectively promote the rapid dissolution and mixing of the treatment agent in water, and can save the amount of the treatment agent, thereby also being beneficial to the health of users.
Preferably, the turbulator provided on the inner wall of the tapered passage portion of decreasing diameter can help the water flow to mix the sucked air more efficiently downstream by increasing the turbulence of the water. The turbulator can be, for example, at least one radial protrusion provided on the inner wall of the tapered channel portion of decreasing diameter or at least one turbulator rib extending longitudinally along the inner wall of the tapered channel portion of decreasing diameter.
The present invention also provides a washing apparatus comprising any one of the microbubble agent cartridge assemblies described above, the microbubble agent cartridge assembly being disposed within the washing apparatus to provide the washing apparatus with a micro-bubble water mixture having a treatment agent dissolved therein.

In order to solve the technical problem of low microbubble generation rate of the existing water injection cartridge, the invention provides a microbubble treatment agent cartridge assembly 52. The microbubble agent cartridge assembly includes a housing 521 and a agent cartridge 522 accommodated in the housing 521. The housing 521 is provided with a microbubble water inlet pipe portion 527, a tapered passage portion 272 with a reduced diameter, an air inlet passage 275, and a microbubble bubbler 274. At least one stage of the diameter-decreasing tapered passage is provided in the diameter-decreasing tapered passage portion 272 along the water flow direction c, and a spray hole 273 is provided on the downstream end of the diameter-decreasing tapered passage portion 272. The tapered passage portion 272 of reduced diameter is positioned such that the water flow entering the micro bubble inlet pipe portion 527 will be subjected to pressurization within the at least one stage of tapered passage of reduced diameter and be expandingly ejected from the ejection orifice 273 to generate a negative pressure near the ejection orifice 273. The air intake passage 275 is positioned close to the spray hole 273 so that external air is sucked through the air intake passage 275 by negative pressure and mixed with the sprayed water to form bubble water. The bubble water flows through the microbubble bubbler 274 to form microbubble water and is sprayed into the treatment agent box 522. Therefore, compared with the water injection box with the micro-bubble generator in the prior art, the micro-bubble treatment agent box assembly has the advantages that the micro-bubble generation capacity is greatly improved, the dissolving speed, the dissolving rate and the mixing degree of the treatment agent in water are improved, and the consumption of the treatment agent can be further saved.
The "tapered passage portion with a reduced diameter" as referred to herein means a structure in which the diameter of the passage formed inside the portion or the cross-section perpendicular to the water flow direction is gradually reduced so that the passage is substantially tapered.
Fig. 1 is a schematic perspective view of an embodiment of the microbubble treatment agent cartridge assembly of the present invention, fig. 2 is a front view of the embodiment of the microbubble treatment agent cartridge assembly of the present invention shown in fig. 1, and fig. 3 is a top view of the embodiment of the microbubble treatment agent cartridge assembly of the present invention shown in fig. 1.
Referring to fig. 1-3, in one or more embodiments, the microbubble treatment cartridge assembly 52 includes a housing 521 and a treatment cartridge 522. The process cartridge 522 can be accommodated in the housing 521, and is movable within the housing 521 so as to be drawn into and out of the housing 521. In this context, a treatment agent includes a detergent, one or more laundry care agents, which may be, for example, a softener, a disinfectant solution, and the like.
As shown in fig. 1-3, in one or more embodiments, the housing 521 is provided with a main water inlet pipe portion 525, a softener water inlet pipe portion 526, and a micro-bubble water inlet pipe portion 527. The main inlet manifold portion 525, the conditioner inlet manifold portion 526, and the micro-bubble inlet manifold portion 527 are all disposed on the top of the housing 521 and are distributed on both sides of the top, wherein the micro-bubble inlet manifold portion 527 and the conditioner inlet manifold portion 526 are located on the same side of the housing 521. Both the main inlet conduit portion 525 and the conditioner inlet conduit portion 526 may be connected to an external water source, and supply non-micro bubble water, such as tap water or well water or other water sources, to the detergent chamber 221 and the care agent chamber 222 in the treatment agent box 522, respectively, so that both belong to the non-micro bubble inlet conduit portion. The microbubble water inlet pipe part 527 is configured to supply microbubble water to the process cartridge 522. Two symmetrical first fixing portions 523 and two symmetrical second fixing portions 524 are provided on the left and right sides of the housing 521, respectively, with respect to the drawing direction of the process cartridge 522. The first fixing portion 523 and the second fixing portion 524 are used to fix the microbubble agent cartridge assembly 52 to, for example, the washing apparatus, for example, by screw connection or welding connection. In alternative embodiments, only one non-microbubble water inlet pipe portion, such as the main water inlet pipe portion 525, or more than two non-microbubble water inlet pipe portions may be provided on the housing 521 in addition to the microbubble water inlet pipe portion 527, as needed.
Fig. 4 is a cross-sectional view of a first embodiment of the microbubble agent cartridge assembly 52 of the present invention taken along the section line a-a of fig. 3. As shown in fig. 4, in one or more embodiments, the treatment agent box 522 has a detergent chamber 221 and a conditioner chamber 222 arranged in parallel. The detergent chamber 221 is provided for containing detergent. The conditioner chamber 222 is configured to contain a conditioner. In an alternative embodiment, only one chamber for accommodating, for example, detergent can be provided in the treatment agent box 522. In alternative embodiments, multiple chambers can be provided in the treatment agent cartridge 522, for example two or more treatment agent chambers included in the chambers, each for containing a different treatment agent. In one or more embodiments, main inlet conduit portion 525 is configured to provide tap water to detergent chamber 221, and softener inlet conduit portion 526 is configured to provide tap water to conditioner chamber 222.
Referring to fig. 4, the micro-bubble water inlet tube part 527 has an inlet end 271, the inlet end 271 being used to connect to an external water source to allow water to flow into the micro-bubble water inlet tube part 527 in the flow direction c when needed. A tapered passage portion 272 of which the diameter is reduced is formed in the horizontal portion of the microbubble water inlet pipe portion 527. A one-step diameter-decreasing tapered passage 272a is formed inside the diameter-decreasing tapered passage portion 272 along the water flow direction c. Alternatively, two or more stages of the tapered passage with a reduced diameter may be formed in the tapered passage portion 272 with a reduced diameter in the water flow direction. A nozzle hole 273 is formed on the downstream end of the tapered passage portion 272 having a reduced diameter. The nozzle holes 273 communicate the primary tapered passage 272a with the flow channel located downstream of the nozzle holes 273. The water flow after entering the microbubble water inlet pipe portion 527 must flow through the one-stage tapered passage 272a having a reduced diameter to be pressurized therein. The pressurized water flow is rapidly expanded to be ejected to the downstream flow path through the injection hole 273 and causes a negative pressure in the vicinity of the injection hole 273. The air intake passage 275 is formed on the lower tube wall of the horizontal portion of the microbubble water inlet tube part 527, and is positioned close to the nozzle holes 273. Accordingly, under the negative pressure, the external air is drawn into the micro bubble water inlet pipe part 527 through the air inlet passage 275 and mixed with the water flow ejected from the nozzle holes 273 to generate the bubble water. The microbubble bubbler 274 is also arranged in the horizontal portion of the microbubble water inlet pipe portion 527, and is located downstream of the tapered passage portion 272 that is reduced in diameter. The microbubble bubbler 274 is disposed transversely to the microbubble water inlet pipe part 527, and therefore, the bubble water needs to flow through the microbubble bubbler 274 before exiting the microbubble water inlet pipe part 527 and be cut and mixed by the microbubble bubbler 274 to generate the microbubble water. The micro-bubble water is then sprayed into the detergent chamber 221 and/or the conditioner chamber 222 of the treatment agent cartridge 522, thereby helping to rapidly dissolve the detergent located in the detergent chamber 221 and/or the conditioner, such as a softener, located in the conditioner chamber 222.
In one or more embodiments, turbulators (not shown) can be formed on the inner wall of the primary reduced diameter tapered channel 272 a. In one or more embodiments, the turbulator may be at least one turbulator, such as a plurality of turbulators, extending longitudinally along an inner wall of the tapered passage of decreasing diameter. In an alternative embodiment, the turbulator may be at least one radial protrusion, such as one or more cylindrical protrusions, on the inner wall of the tapered passage of decreasing diameter. In alternative embodiments, the spoiler may be formed on the inner wall of the most downstream stage of the tapered passage with the reduced diameter, or on the inner wall of each stage of the tapered passage with the reduced diameter.
In one or more embodiments, microbubble bubbler 274 is a mesh structure. The mesh structure has at least one fine hole with a diameter of micron order. Preferably, the diameter of the fine pores is between 0 and 1000 microns; more preferably, the diameter of the fine pores is between 5 and 500 μm. The mesh structure may be a plastic fence, a metal mesh, a mesh of polymeric material, or other suitable mesh structure. The plastic fence is generally a polymer fence, which is formed by integrally injection molding a polymer material, or by first forming a sheet from a polymer material and then machining the sheet to form a microporous structure. The polymer material net is usually a net having a microporous structure formed by weaving a polymer material into filaments. The polymer material net may include nylon net, cotton net, polyester net, polypropylene net, etc. Alternatively, the mesh structure may be other mesh structures capable of generating microbubbles, such as a mesh structure consisting of two non-micron honeycomb structures. When the bubble water flows through the mesh structure, the mesh structure produces mixing and cutting effects on the bubble water, thereby producing micro-bubble water.
In one or more embodiments, a shower 276 is also provided on the housing 521. The shower chamber 276 is located above the process agent box 522. The shower chamber 276 is provided at the bottom thereof with a plurality of shower holes (not shown) and is configured to communicate with the detergent chamber 221 and/or the care agent chamber 222 of the treatment agent box 522 to spray the microbubble water from the microbubble bubbler 274 into the detergent chamber 221 and/or the care agent chamber 222.
Fig. 5 is a cross-sectional view of a second embodiment of the microbubble agent cartridge assembly 52 of the present invention taken along the section line a-a of fig. 3. As shown in fig. 5, in this embodiment, the treatment agent box 522 also has the detergent chamber 221 and the care agent chamber 222 arranged in parallel. The detergent chamber 221 is provided for containing detergent. The conditioner chamber 222 is configured to contain a conditioner. The main inlet pipe portion 525 is configured to supply tap water to the detergent chamber 221, and the conditioner inlet pipe portion 526 is configured to supply tap water to the conditioner chamber 222.
Referring to fig. 5, in this embodiment, the microbubble water inlet pipe section 527 has an inlet end 271, and the inlet end 271 is used to connect to an external water source to allow water to flow into the microbubble water inlet pipe section 527 in the flow direction c when necessary. A tapered passage portion 272 having a reduced diameter is formed at the outlet of the microbubble water inlet pipe portion 527. A primary diameter-decreasing tapered passage 272a extending downward is formed inside the diameter-decreasing tapered passage portion 272 along the water flow direction c. Alternatively, two or more stages of the tapered passage with a reduced diameter may be formed in the tapered passage portion 272 with a reduced diameter in the water flow direction. A nozzle hole 273 is formed on the downstream end of the tapered passage portion 272 having a reduced diameter. The nozzle holes 273 communicate the primary tapered passage 272a with the flow channel located downstream of the nozzle holes 273. The water flow after entering the microbubble water inlet pipe portion 527 must flow through the one-stage tapered passage 272a having a reduced diameter to be pressurized therein. The pressurized water flow is rapidly expanded to be ejected to the downstream flow path through the injection hole 273 and causes a negative pressure in the vicinity of the injection hole 273. As shown in fig. 5, in this embodiment, a shower chamber 276 is further provided on the housing 521, and the shower chamber 276 is located above the process cartridge 522. The air intake passage 275 is formed on a connection portion (not shown) between the microbubble water intake pipe portion 527 and the shower chamber 276, and is positioned also close to the nozzle holes 273. Alternatively, an auxiliary air intake passage 275 'may be formed at the junction between the shower chamber 276 and the connection portion, the auxiliary air intake passage 275' being positioned also near the injection hole 273. Alternatively, only the auxiliary intake passage 275' may be provided as the intake passage in the housing 521. Accordingly, under the negative pressure, the external air is sucked into the space surrounded by the connection portion through the air intake passage 275 and/or the auxiliary air intake passage 275' and is mixed with the water flow ejected from the ejection holes 273 to generate bubble water. The microbubble bubbler 274 is disposed at the bottom of the shower chamber 276 and covers the shower holes located on the bottom of the shower chamber 276. Therefore, the bubble water needs to flow through the microbubble generator 274 to form the micro bubble water before being sprayed from the spray holes into the detergent chamber 221 and/or the conditioner chamber 222, thereby helping to rapidly dissolve the detergent in the detergent chamber 221 and/or the conditioner, such as a softener, in the conditioner chamber 222. The embodiment is the same as the above-described embodiment in the non-mentioned portion.
The present invention also provides a washing apparatus including the microbubble agent cartridge assembly 52 of the present invention. The microbubble agent cartridge assembly 52 is disposed within the washing apparatus to provide a treatment agent microbubble water mixture. By the microbubble treating agent box component, the washing capacity of the washing equipment can be improved, the using amount of the detergent can be reduced, the residual amount of the detergent in clothes can be reduced, and therefore the microbubble treating agent box component is not only beneficial to the health of a user, but also can improve the experience of the user.
