Detailed ways

It should be noted that, in the case of no conflict, the embodiments in the application and the technical features in the embodiments can be combined with each other. Undue Limitation of This Application.

In the description of the embodiments of the present application, the orientation or positional relationship of "top", "bottom" and "height direction" refers to the orientation or positional relationship of the laundry treatment equipment and the catalytic device during normal use, for example, Fig. 1, Fig. 2, Fig. 3 and the orientation or positional relationship shown in Figure 5, it should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, in order to specify configuration and operation, and therefore should not be construed as limiting the application.

Please refer to Fig. 1 and Fig. 2, the embodiment of the present application provides a kind of laundry treatment equipment, the laundry treatment equipment includes a cylinder assembly 10, an ozone generator 20 and a catalytic device 30, the cylinder assembly 10 has a washing chamber, and the catalytic device 30 includes a shell Body 31, gas disperser 32 and catalyst 33, housing 31 is formed with accommodating chamber 31a and outlet 31b, outlet 31b communicates accommodating chamber 31a and washing chamber, catalyst 33 and gas disperser 32 are all located in accommodating chamber 31a, gas disperser 32 is in communication with the ozone generator 20 and is used to disperse the ozone from the ozone generator 20 . Specifically, ozone and water react under the catalytic action of the catalyst 33 to generate strong oxidizing substances.

The oxidizing property of strong oxidizing substances is higher than that of ozone, and strong oxidizing substances include but not limited to hydroxyl radicals and the like. Taking hydroxyl radicals as an example, hydroxyl radicals have a very strong electron-accepting ability, that is, oxidation ability. The strong oxidative properties of hydroxyl radicals enable them to destroy the protein structure of bacteria or viruses and play a role in disinfection and sterilization. Hydroxyl radicals can also chemically react with pollutants to oxidize pollutants into CO2, H2O or inorganic salts, etc. No secondary pollution. Therefore, compared with ozone, hydroxyl radicals not only have stronger sterilization and disinfection effects, but also have stronger decontamination capabilities, and there is no secondary pollution.

In the clothing treatment equipment provided in the embodiment of the present application, the ozone from the ozone generator 20 is dispersed by the gas disperser 32 and then enters the accommodating chamber 31a, the water in the washing chamber can enter the accommodating chamber 31a, and the ozone and water are catalyzed by the catalyst 33 After the reaction, strong oxidizing substances such as hydroxyl radicals are generated. In this way, the water liquid rich in oxidizing substances such as ozone and hydroxyl radicals jointly forms a mixture fluid, which improves the sterilization, disinfection and decontamination effects. The ozone is dispersed through the gas disperser 32 to form tiny bubbles, for example, the inner diameter of the bubbles is at the micronano level. In this way, on the one hand, ozone disperses into the water liquid, which increases the solubility of ozone in the water liquid, and the concentration of ozone is higher, which can not only increase the catalytic reaction rate, accelerate the catalytic reaction, but also generate more hydroxyl radicals, which improves the concentration of hydroxyl radicals. On the other hand, when the clothes are in contact with the mixture fluid rich in ozone and hydroxyl radicals, the disinfection and decontamination effect on the clothes is better. It can avoid color crossing of clothes, so that users can use it more conveniently and improve user experience.

In one embodiment, under certain test conditions, the concentration of hydroxyl radicals in the aqueous solution reaches about 0.31 mMol (mmol) by dispersing ozone through the gas disperser 32 , thus greatly increasing the concentration of hydroxyl radicals.

The specific type of the laundry treatment equipment is not limited, for example, the laundry treatment equipment may be an all-in-one washer-dryer or a washing machine, and so on. The clothes processing equipment may be a wave-wheel washing machine or a rolling washing machine or the like.

Taking the laundry treatment equipment as an integrated washing and drying machine as an example, when washing, there is water in the washing chamber and the containing chamber 31a, and ozone enters the containing chamber 31a, and at least part of the ozone and water are catalyzed by the catalyst 33 to generate hydroxyl radicals. Ozone and hydroxyl radicals enter the washing chamber. In this way, during the washing process, ozone and hydroxyl radicals come into contact with the clothes to achieve the purpose of disinfection, decontamination and color fixation. When drying, there is no water liquid in the washing chamber, and there may be no water in the receiving chamber 31a. In this way, ozone can be delivered to the receiving chamber 31a, and the ozone does not undergo a catalytic reaction, but directly enters the washing chamber, that is to say, Ozone is directly used for sterilization and disinfection.

In one embodiment, please refer to FIG. 1 , the bottom of the cylinder assembly 10 is formed with a drain port communicating with the washing chamber, the catalytic device 30 is located outside the cylinder assembly 10 and arranged on the bottom side of the cylinder assembly 10, and the drain port communicates with the outlet 31b. The space outside the barrel assembly 10 is relatively large, which not only facilitates loading and unloading of the catalytic device 30 , but also facilitates subsequent maintenance of the catalytic device 30 . The catalytic device 30 is located on the bottom side of the barrel assembly 10 , and the catalytic device 30 is located at a lower position, so that the water flow can smoothly enter the accommodating chamber 31a through the water outlet and the outlet 31b under the action of gravity. For example, when washing, the washing chamber is filled with water, and the water surface naturally covers the chamber 31a, so that the catalyst 33 in the chamber 31a is immersed in the water, so that ozone can fully contact with the water when it enters the chamber 31a.

In one embodiment, please refer to FIG. 1 and FIG. 2 , the laundry treatment equipment includes a drainage pipeline and a branch pipe both arranged on the bottom side of the cylinder assembly 10, and the drainage pipeline is connected to the drain port to discharge the water in the washing chamber. For example, when the washing is finished, the water in the washing chamber is discharged through the drainage pipeline. The branch pipe connects the drain line and the outlet 31b. On the one hand, at the beginning of washing, water begins to enter the washing chamber, and since the drainage pipeline, the branch pipe and the catalytic device 30 are all located at the lower water level of the cylinder assembly 10, when the washing begins, even if the water in the cylinder assembly 10 Only a small amount of water can also ensure that there is water in the branch pipe and the catalytic device 30. The branch pipe and the catalytic device 30 can be filled with water in a short time, and the ozone can contact the water for catalytic reaction to generate hydroxyl radicals. During the drainage process, water can be kept in the accommodation chamber 31a until the drainage is completed, that is to say, during the entire washing process, water in the accommodation chamber 31a contacts with the catalyst 33 and ozone, ensuring that the entire washing process Both can generate hydroxyl radicals, which is beneficial to increase the content and concentration of ozone and hydroxyl radicals in water, and improve the disinfection and sterilization effect. On the other hand, with this design, the catalytic device 30 can be flexibly arranged in the limited space of the laundry treatment equipment by connecting the drain port and the outlet 31b through branch pipes without changing the structural layout and piping of the original laundry treatment equipment as much as possible.

The structure of the drainage pipeline is not limited. As an example, in one embodiment, the drainage pipeline includes a drainage pipe and a drainage valve arranged on the drainage pipe. The drainage valve is used to open or close the drainage pipeline, and the branch pipe is located upstream of the drainage valve. And connected with the drain pipe. During the washing process, the drain valve closes the drain water channel, and the part of the drain pipe upstream of the drain valve is still filled with water, so that, during the washing process, the water from the drain line enters the accommodating chamber 31a.

In one embodiment, please refer to FIG. 1 and FIG. 2 , the laundry treatment equipment includes an air pump 40 connected to the ozone generator 20 to drive the flow of ozone. The air pump 40 pumps ozone into the chamber 31a. The flow rate of the ozone is relatively high, and the ozone can stir the flow of the water in the chamber 31a, so that the mixture fluid keeps flowing and the dissolution rate of the detergent can be increased. The air pump 40 is used to pump the ozone to facilitate the control of the flow rate of the ozone. For example, the pressure of the air pump 40 can be adjusted to adjust the flow rate of the ozone, thereby controlling the reaction efficiency of the catalytic reaction to a certain extent. Positive pressure is formed on the side where the ozone generator 20 is located, which can prevent the water in the washing chamber from flowing backward into the ozone generator 20, that is to say, the air pump 40 can also play a role in limiting the direction of water flow, so that structures such as a one-way valve can be avoided . In addition, since the side where the ozone generator 20 is located is under positive pressure, fine objects such as dandruff in the water flow are not easy to enter the ozone generator 20 or into the delivery pipeline of ozone. Even if tiny objects such as dandruff enter the ozone delivery pipeline, these objects that block the delivery pipeline can be blown out by the pressure of the air pump 40, thereby ensuring the smooth flow of the delivery pipeline. Therefore, the use of the air pump 40 reduces the number of parts and simplifies the structure and control method.

The location of the ozone generator 20 on the laundry treatment equipment is not limited. For example, in one embodiment, please refer to FIG. In this way, the ozone generator 20 is located at a higher position of the cylinder assembly 10, and it is difficult for the water flow to flow back into the ozone generator 20. Correspondingly, it is difficult for dander and other debris in the water liquid to enter the gas pipeline of the ozone generator 20. To a certain extent, it avoids the blockage of the air pipeline, and improves the stability and reliability of the clothes processing equipment.

In one embodiment, referring to Fig. 5 and Fig. 6, the housing 31 is formed with an air inlet 31c, the air inlet end of the gas disperser 32 is connected to the air inlet 31c, and the air inlet 31c is connected to the ozone generator 20 through a trachea The ozone from the ozone generator 20 can be delivered to the gas disperser 32 through the gas pipe and the gas inlet 31c.

The structure of the barrel assembly 10 is not limited. As an example, in one embodiment, the barrel assembly 10 includes an inner barrel and an outer barrel, the inner barrel is rotatably sleeved in the outer barrel, and the space in the inner barrel is a washing chamber. A plurality of water passage holes are formed on the peripheral side wall of the inner cylinder, and the water passage holes communicate with the space in the washing chamber and the outer tub, and the outer tub is used for holding water, and the drain port is formed on the outer tub. During washing, clothes are contained in the washing cavity, and water liquid is contained in the inner space of the outer tub. When draining, for example, after washing is completed, the water in the outer tub is discharged through the drain.

The specific structure of the gas disperser 32 is not limited. Exemplarily, the gas disperser 32 includes but is not limited to nozzles, aeration membranes or aerators, etc. The specific type of the aerator is not limited. For example, the aerator can be It is a tube or disc aerator.

In one embodiment, the gas diffuser 32 includes a body, and the body is provided with a plurality of micropores passing through the body. Ozone enters the chamber through the micropores, and the ozone is in strong contact with the water around the micropores, and the ozone in the gas phase transfers to the water in the liquid phase for mass transfer, thereby forming many tiny bubbles. Micro-bubbles have small bubble diameter, large gas-liquid interface area, and uniform bubble diffusion. In this way, by reducing the size of the bubbles, increasing the number of bubbles, and increasing the degree of turbulence of the water and liquid, the solubility of ozone is improved.

In one embodiment, a plurality of microwells are arranged in an array. A plurality of micropores can disperse ozone, and the pore size of the micropores is small and the number is large, further improving the solubility of ozone.

The diameter of the micropores is not limited. Exemplarily, in one embodiment, the diameter of the micropores is not greater than 100 μm (micrometer).

In one embodiment, referring to Fig. 1 and Fig. 2, the gas disperser 32 includes an air shell 321 with an air outlet and an aeration membrane, the air shell 321 communicates with the ozone generator 20, and the aeration membrane covers the air outlet to disperse ozone . The inner space of the gas shell 321 is used to accommodate a certain volume of ozone, and the ozone is aerated through the aeration membrane to achieve the purpose of dispersing the ozone.

The aeration membrane is a kind of air-permeable dense membrane, and there are multiple aeration holes densely distributed on the aeration membrane. In this way, the ozone is dispersed into tiny bubbles by the aeration holes.

The pore size of the aeration hole is not limited. Exemplarily, the pore size of the aeration hole is between 0.1 μm and 0.4 μm.

The type of the aeration membrane is not limited, for example, the aeration membrane may be a silicone rubber membrane or a hydrophobic polymer membrane and the like. In this way, the aeration membrane has certain elastic force. In one embodiment, the aeration membrane is wrapped around the air outlet of the air shell 321 . In this way, during the process of ozone flowing out from the air outlet, the ozone forces the aeration membrane to deform, thereby making the aeration hole larger, so that the ozone flows out through the aeration hole. When the delivery of ozone stops, the aeration membrane recovers its deformation and the aeration holes are closed again, which can effectively prevent external water from pouring back into the air case 321 through the aeration holes.

The shape of the gas shell 321 is not limited. For example, in one embodiment, please refer to FIG. 2 , the gas shell 321 is in the shape of a flat disk. For example, the projected shape of the gas shell 321 along the height direction of the casing 31 includes but not limited to a circle, an ellipse, or a polygon. That is to say, the cross-sectional shape of the gas shell 321 is roughly circular, elliptical or polygonal, etc., and the height dimension of the gas shell 321 is much smaller than its cross-sectional area. In this way, the outer surface area of the gas shell 321 is large, and the area that can be used to arrange the aeration membrane on the gas shell 321 is large, thereby increasing the gas output of ozone; Too much space.

The position of the gas diffuser 32 is not limited. For example, in one embodiment, please refer to FIG. on the side wall. In such a design, no matter whether the water liquid is filled with the chamber 31a, there is water liquid at the bottom of the chamber 31a, and the ozone moves from the bottom of the chamber 31a to the top of the chamber 31a, so that the ozone, water and catalyst 33 are fully contacted, The generated ozone and hydroxyl radicals can smoothly flow out from the outlet 31b at the top of the casing 31 due to their low density. The outlet 31b is formed on the peripheral side wall of the casing 31, which can minimize the space occupied by the casing 31 in the height direction of the laundry treatment device, making the internal structure of the laundry treatment device more compact.

In one embodiment, referring to FIG. 2 , FIG. 5 and FIG. 8 , the catalytic device 30 includes a partition 34 disposed in the chamber 31a, the partition 34 is formed with a plurality of through holes 34a, and the partition 34 separates the chamber 31a A first chamber 31a' and a second chamber 31a", the gas diffuser 32 is located on one side of the first chamber 31a', and the outlet 31b is located on one side of the second chamber 31a". The catalyst 33 is located in the second chamber 31a". The first chamber 31a' gives space and time for the ozone and water to fully mix. After the ozone and water are fully mixed, they enter the second chamber 31a" through the through hole 34a. , ozone and water are catalyzed by the catalyst 33 in the second chamber 31a" to generate hydroxyl radicals. In this way, the reaction rate is faster and the reaction is more complete by mixing first and then catalyzing.

In one embodiment, please refer to FIG. 3 to FIG. 5 , the housing 31 is cylindrical, the axial direction of the housing 31 is consistent with the direction of the top and bottom, the partition 34 is roughly disc-shaped, and the partition 34 is along the diameter of the housing 31. Therefore, both the first chamber 31a' and the second chamber 31a" are approximately cylindrical cavities.

The type of the catalyst 33 is not limited. For example, in one embodiment, please refer to FIG. 2 , the catalyst 33 is in the form of particles, and the catalyst 33 in the form of particles is filled in the second chamber 31 a ″.

In one embodiment, referring to Fig. 5 to Fig. 7, the catalytic device 30 includes a baffle 35 arranged in the second chamber 31a". The baffle 35 can change the mixture fluid formed by ozone, water flow and hydroxyl radicals, etc. The flow direction, flow velocity, etc., to generate turbulent flow in the second chamber 31a", increasing the contact time, contact times, reaction time, etc. of ozone, water liquid and catalyst 33. In this way, the reaction between ozone and water is more thorough and sufficient, and the total amount and concentration of hydroxyl radicals are increased.

In one embodiment, please refer to FIG. 5 to FIG. 7 , the baffle plate 35 is formed with a plurality of flow holes 35a. The flow hole 35a helps to ensure the smooth flow of the mixture fluid.

In one embodiment, please refer to FIG. 5 to FIG. 7 , the baffle 35 is spaced apart from the peripheral side wall of the second chamber 31a ″ to form a flow area 35b. The baffle 35 can be fixed in the second chamber 31a", the baffle 35 can also be fixed on the partition 34. On the one hand, the mixture fluid formed by ozone, water flow and hydroxyl radicals, etc. can flow through the flow hole 35a and the flow region 35b, and the flow rate of the mixture fluid flow through the flow region 35b and the flow hole 35a is not the same, specifically, the The flow area of the flow area 35b is different from the flow area of the flow hole 35a. For example, the flow area of the flow area 35b is larger, and the flow area of the flow hole 35a is smaller, and the surrounding parts of the flow hole 35a can be The flow of the mixed fluid is hindered, so that the mixed fluid flows through the flow area 35b, the flow velocity and the flow direction of the flow hole 35a are different, the flow field of the mixed fluid in the mixing chamber produces turbulent flow, and the mixed fluid moves irregularly, for example, there are The partial velocity perpendicular to the baffle plate 35 is produced, and like this, the mixture fluid flows from the gas disperser 32 to the outlet 31b along the tortuous path, increasing the contact time, the number of times of contact, the reaction time, etc. of ozone, water liquid and catalyst 33, like this , so that the ozone and water react more thoroughly and fully, increasing the total amount and concentration of hydroxyl radicals. On the other hand, the solubility of ozone and hydroxyl radicals in water is easy to reach a saturated state under conditions such as a certain temperature, and the flow hole 35a and the flow area 35b are all convenient for the flow of the mixture fluid. Under the condition of changing the flow direction of the mixture fluid, ensure The fluid has a certain outflow rate, so that the baffle plate 35 is prevented from obstructing the movement of the fluid too much, so as to ensure that the hydroxyl radicals can be fully dissolved in the water flow and enter the washing chamber with the water flow.

It should be noted that the flow area refers to the cross-sectional area perpendicular to the fluid flow direction.

In one embodiment, please refer to FIG. 2 , the angle α between the baffle plate 35 and the partition plate 34 is less than 90 degrees. For example, the angle α between the baffle 35 and the partition 34 is 0 degree, that is, the baffle 35 is parallel to the partition 34 . For another example, the angle α between the baffle plate 35 and the partition plate 34 is 45 degrees. In this way, the mixture fluid contacts the baffle plate 35 at a certain angle, and the baffle plate 35 can slightly slow down the flow velocity of the mixture fluid, increase the residence time of the mixture fluid, prolong the catalytic reaction time, and avoid excessively reducing the flow velocity of the mixture fluid to ensure the deflection The flow plate 35 can maintain a certain flow velocity.

In an embodiment, please refer to FIG. 2 and FIG. 5 , there are multiple baffles 35 , and the multiple baffles 35 are arranged alternately at intervals along the height direction of the casing 31 . That is to say, the plurality of baffles 35 form a plurality of flow areas 35 b , and the plurality of flow areas 35 b are arranged in layers at intervals along the height direction of the casing 31 . The flow path of the mixture fluid is tortuous and changeable, like this, in the process of flowing from the gas disperser 32 to the outlet 31b, the mixture fluid has more and richer flow paths, for example, part of the mixture fluid can pass through the process of each layer of baffles 35 Orifice 35a circulates; Another example, part of the mixture fluid can be circulated through each layer of flow area 35b; Another example, part of the mixture fluid can be passed through the flow area 35b and flow hole 35a in turn, etc., so that the mixture fluid is forced to The path crosses multiple times through the second chamber 31a", which greatly increases the degree of turbulence.

In one embodiment, please refer to FIG. 2 and FIG. 5 , projections of two adjacent flow-passing regions 35b along the height direction of the casing 31 do not overlap at least partially. That is to say, two adjacent flow passage regions 35 b are arranged in a staggered position, for example, two adjacent flow flow regions 35 b are arranged in a staggered direction along the radial direction of the casing 31 . Like this, further strengthen the turbulent flow that the flow field of mixture fluid produces, and the motion path of mixture fluid is more tortuous and diversified, and mixture fluid moves irregularly, has further increased the contact time of ozone, water liquid and catalyst 33, contact times, reaction. Time and so on, in this way, the reaction between ozone and water is more thorough and sufficient, and the total amount and concentration of hydroxyl radicals are increased.

There is no limit to the degree to which the projections of two adjacent flow-through regions 35b along the height direction of the casing 31 do not overlap at least partially. For example, in one embodiment, two adjacent flow-flow regions 35b along the height direction of the casing 31 The projections of are only partially non-overlapping. That is to say, the projections of two adjacent flow passage regions 35 b along the height direction of the casing 31 partially overlap, and the projections of two adjacent flow flow regions 35 b along the height direction of the casing 31 do not overlap. In another embodiment, please refer to FIG. 2 and FIG. 5 , the projections of two adjacent flow-through areas 35 b along the height direction of the casing 31 do not overlap at all. That is to say, the projections of two adjacent flow passage regions 35b along the height direction of the casing 31 are spaced apart, and the projections of two adjacent flow flow regions 35b along the height direction of the casing 31 have no overlapping area. In this way, the mixture fluid is further forced to change the flow direction and flow path, so that the reaction is more thorough.

In one embodiment, please refer to Fig. 2, Fig. 5 to Fig. 7, the catalytic device 30 includes a baffle 36 arranged in the second chamber 31a", the baffle 36 is a non-porous structure. The mixture fluid can only bypass The baffle plate 36 flows, but cannot pass through the baffle plate 36. In this way, the baffle plate 36 hinders the mixture fluid to a greater extent, and can increase the residence time of the mixture fluid in the second chamber 31a "to a greater extent, The catalytic reaction can be more thorough.

It can be understood that the baffle 36 can hinder the flow of the mixture fluid to a certain extent, but cannot prevent the flow of the mixture fluid, that is to say, the outer periphery of the baffle 36 is a space through which the mixture fluid can flow.

In one embodiment, referring to Fig. 2, Fig. 5 to Fig. 7, the baffle plate 36 is located between the inner surface of the second chamber 31a" and the baffle plate 35 closest to the outlet 31b. For example, the baffle plate 36 is located between the inner top surface of the second chamber 31a" and the baffle plate 35 at the highest position. That is to say, the baffle 36 is arranged close to the outlet 31b. On the one hand, the baffle 36 can effectively prevent the mixture fluid from directly flowing out of the outlet 31b, prolonging the residence time of the mixture fluid; Excessive interference with the flow of the mixture fluid avoids a sharp reduction in the flow velocity of the mixture fluid, ensuring smooth and multi-path flow of the mixture fluid in the second chamber 31a".

The number of the baffles 36 is not limited, for example, in one embodiment, the number of the baffles 36 is one. In another embodiment, please refer to FIG. 2 and FIG. 5 , there are multiple baffles 36 , for example two, and the baffles 36 are arranged alternately. For example, the baffles 36 are alternately arranged along a direction perpendicular to the height direction of the housing 31 . For example, the baffles 36 are arranged in a staggered manner along the radial direction of the casing 31 . In this way, the plurality of baffles 36 play the role of blocking the flow of the mixture fluid multiple times, which can more effectively prolong the residence time of the mixture fluid in the second chamber 31 a ″.

The specific location of the baffle 36 is not limited. Please refer to FIG. 2 , FIG. 5 to FIG. 7 . In one embodiment, the baffle 36 is fixedly connected to the inner peripheral wall of the casing 11 .
