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 filling cartridge and is mixed with detergent or softener, etc. in the water filling cartridge, and then enters the washing drum for washing the laundry. However, such a fine bubble generator can only generate fine bubbles by virtue of very limited air carried within the liquid flowing therethrough, and therefore, the fine bubble generator cannot supply a sufficient amount of micro-bubble water of micro-bubbles to the water injection cartridge, thereby affecting the dissolution of the detergent or softener.
Accordingly, there is a need in the art for a new solution to the above problems.
Disclosure of Invention

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. At least one water inlet pipe portion is provided on the case 521. At least one of the at least one water inlet pipe part is internally provided with at least one stage of tapered part with the diameter reduced and a micro-bubble bubbler. At least one of the at least one water inlet pipe part is also provided with an air inlet hole on the pipe wall, and the air inlet hole is positioned between the at least one-stage diameter-reduced conical part and the microbubble bubbler and is communicated with an air inlet pipe arranged on the shell 521. And the top end of the most downstream stage of the diameter-reduced conical part is provided with a spray hole which is arranged to ensure that water flowing through the at least one stage of the diameter-reduced conical part can be sprayed out through the spray hole in an expanding way and generate negative pressure near the air inlet hole, so that air can be sucked into the water inlet pipe part from the air inlet pipe and mixed with the water flow to generate bubble water. The bubble water passes through the microbubble bubbler to be changed into micro bubble water, and then 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.
In one or more embodiments, at least one stage of a reduced diameter cone and a microbubble bubbler are provided within one or more of the inlet pipe sections. Alternatively, at least one stage of diameter-reducing cone and microbubble bubbler are provided in each of the water inlet pipe portions.
The "tapered portion with a reduced diameter" as referred to herein means a structure in which the diameter of the passage formed inside the portion is gradually reduced so that the passage is tapered.
Fig. 1 is a schematic perspective view of an embodiment of a 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. Herein, the treating agent includes a detergent, one or more laundry care agents, etc., and the laundry care agent may be, for example, a softener, a bactericide, etc.
As shown in fig. 1 to 3, the housing 521 is provided with a main water inlet pipe portion 525 and an auxiliary water inlet pipe portion 526. In one or more embodiments, the main inlet pipe portion 525 and the auxiliary inlet pipe portion 526 are both disposed on the top of the housing 521 and are distributed on both sides of the top. Both the main inlet pipe portion 525 and the auxiliary inlet pipe portion 526 may be connected to an external water source. Two symmetrical first connecting portions 523 and two symmetrical second connecting 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 connection portion 523 and the second connection 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 inlet pipe portion can be provided on the housing 521, or more than two inlet pipe portions can be provided, as desired.
Fig. 4 isbase:Sub>A cross-sectional view of an embodiment of the microbubble agent cartridge assembly 52 of the present invention taken along the section linebase:Sub>A-base:Sub>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, including, for example, two or more treatment agent chambers, each for containing a different treatment agent.
Referring to FIG. 4, the main inlet conduit portion 525 has an inlet end 251 for connection to an external water source to allow water to flow into the main inlet conduit portion 525 in the flow direction d when desired. In one or more embodiments, a primary diameter-reducing taper 252 and a microbubble bubbler 253 are provided within the main inlet pipe portion 525. The water flow is accelerated by the gradually narrowing flow passage section as it passes through the primary reduced diameter tapered portion 252. A nozzle hole 255 is provided at the top of the primary diameter-reduced tapered portion 252, and the nozzle hole 255 connects the passage in the primary diameter-reduced tapered portion 252 to the passage downstream in the main water inlet pipe portion 525. The water flow accelerated by the primary diameter-reduced tapered portion 252 is jetted expansively from the jet holes 255 and thus causes a negative pressure in the passage downstream of the main water inlet pipe portion 525. An air inlet 256 is also provided on the wall of the main water inlet pipe portion 525. The intake hole 256 is positioned between the primary diameter-decreasing tapered portion 252 and the microbubble bubbler 253 downstream of the injection hole 255, so that the intake hole 256 is in a negative pressure region caused by the injection hole 255. The intake holes 256 communicate with the first intake pipe 254. Accordingly, a large amount of outside air is drawn from the first intake pipe 254 into the main water inlet pipe portion 525 through the intake holes 256 in the direction e by the negative pressure and mixed with the water flow in the main water inlet pipe portion 525 to generate bubble water containing a large amount of bubbles. The bubble water further flows downstream and passes through the microbubble bubbler 253. While passing through the microbubble bubbler 253, the bubble water is further mixed and cut, thereby generating microbubble water containing a large amount of microbubbles. The micro bubble water then flows to the first shower chamber 257 located below the main water inlet pipe portion 525 and above the detergent chamber 221, and is uniformly sprayed into the detergent chamber 221 through the first shower chamber 257, thereby helping to rapidly dissolve the detergent located in the detergent chamber 221.
In alternative embodiments, more than one step of a reduced diameter taper can be provided within the main inlet pipe portion 525, such as two or more steps of reduced diameter tapers, to further accelerate the water flow. In this case, the injection holes are arranged at the tops of the most downstream one-step tapered portions of decreasing diameter in the water flow direction.
In one or more embodiments, turbulators (not shown) can be formed on the inner wall of the primary reduced diameter taper 252. 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 stage of reduced diameter tapered portion. 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 step of reduced diameter tapers. In alternative embodiments, the turbulator may be formed on the inner wall of the most downstream stage of the reduced diameter taper, or on the inner wall of each stage of the reduced diameter taper.
In one or more embodiments, the outer wall of the primary reduced diameter conical portion 252 is spaced apart from the inner wall of the main inlet pipe portion 525 such that an annular gap (not labeled) is formed between the outer wall of the primary reduced diameter conical portion 252 and the inner wall of the main inlet pipe portion 525. The annular gap facilitates the mixing of the air with the water flow, thereby generating more micro-bubbles.
In one or more embodiments, the microbubble bubbler 253 is a mesh structure, and the mesh structure is fixed inside the main inlet pipe section 525, extending along the inner transverse cross-section of the main inlet pipe section 525, such that bubble water from upstream needs to pass through the mesh structure to flow to the downstream first shower chamber 257. 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 micrometers. 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 web is generally a web 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 pore network structure may be another pore network structure capable of generating micro bubbles, for example, a pore network structure composed of two non-micron-sized 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.
With continued reference to FIG. 4, the secondary inlet conduit portion 526 has an inlet end 261 for connection to an external water source to allow water to flow into the secondary inlet conduit portion 526 in the flow direction c when desired. In one or more embodiments, a one-step reduced diameter conical portion 262 and a microbubble bubbler 263 are provided in the subsidiary feed pipe portion 526. The water flow is accelerated as it passes through the primary reduced diameter conical portion 262 due to the progressively converging flow passage cross-section. At the top of the primary diameter-reduced tapered portion 262, there is provided an injection hole 265, the injection hole 265 communicating the passage in the primary diameter-reduced tapered portion 262 with the passage downstream in the auxiliary water inlet pipe portion 526. The water flow accelerated by the primary diameter-reduced tapered portion 262 is expandingly ejected from the injection holes 265 and thus causes a negative pressure in the passage downstream of the auxiliary water inlet pipe portion 526. Air inlet holes 266 are also provided on the wall of the auxiliary water inlet pipe portion 526. The intake hole 266 is positioned between the primary diameter-reducing tapered portion 262 and the microbubble bubbler 263 located downstream of the injection hole 265, so that the intake hole 266 is within a negative pressure region caused by the injection hole 265. The intake holes 266 communicate with the second intake pipe 264. Accordingly, a large amount of outside air is drawn from the second intake pipe 264 into the subsidiary intake pipe portion 526 through the intake holes 266 in the direction e by the negative pressure and mixed with the water flow in the subsidiary intake pipe portion 526 to generate bubble water containing a large amount of bubbles. The bubbled water flows further downstream and through the microbubble bubbler 263. While passing through the microbubble bubbler 263, the bubble water is further mixed and cut, thereby generating microbubble water containing a large amount of microbubbles. The micro-bubble water then flows to the second shower chamber 267 located below the auxiliary water inlet pipe part 526 and above the care agent compartment 222, and is uniformly sprayed into the care agent compartment 222 through the second shower chamber 267, thereby helping to rapidly dissolve the care agent located in the care agent compartment 222.
In alternative embodiments, more than one step of a reduced diameter taper can be provided in the auxiliary feed pipe portion 526, such as two or more steps of a reduced diameter taper, to further accelerate the water flow. In this case, the nozzle holes are arranged at the top of the most downstream one-step diameter-reducing tapered portion in the water flow direction.
In one or more embodiments, turbulators (not shown) can be formed on the inner wall of the primary reduced diameter taper 262. 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 stage of reduced diameter tapered portion. 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 stage of reduced diameter tapers. In alternative embodiments, the spoiler may be formed on the inner wall of the most downstream step-diameter-reducing tapered portion, or on the inner wall of each step-diameter-reducing tapered portion.
In one or more embodiments, the outer wall of the primary reduced diameter conical portion 262 is spaced apart from the inner wall of the secondary feed pipe portion 526 such that an annular gap (not labeled) is formed between the outer wall of the primary reduced diameter conical portion 262 and the inner wall of the secondary feed pipe portion 526. The annular gap facilitates the mixing of the air with the water flow, thereby generating more micro-bubbles.
In one or more embodiments, the configuration of the microbubble bubbler 263 in the auxiliary water inlet pipe section 526 and the configuration of the microbubble bubbler 253 in the main water inlet pipe section 525 may be the same, for example, both have a mesh structure, and the mesh structure has at least one fine hole with a diameter of the order of micrometers.
In one or more embodiments, the first and second intake pipes 254, 264 are each integrally joined to the housing 521. Alternatively, the first intake pipe 254 and/or the second intake pipe 264 may be configured independently of the housing 521.
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.
