Disclosure of Invention

Embodiments according to the present application aim to ameliorate at least one of the technical problems of the prior art or the related art.

In view of this, an object according to an embodiment of the present application is to provide a laundry treating apparatus.

In order to achieve the above object, there is provided a laundry treating apparatus according to an embodiment of the present application, including: an ozone generator for generating ozone; the air pump is connected with the ozone generator and used for driving ozone; a laundry treating drum; the catalyst cavity is communicated with the clothes treatment barrel and the ozone generator, and is used for containing a catalyst which is used for carrying out chemical reaction with ozone and water.

In the technical scheme, the catalyst cavity is communicated with the clothes treatment barrel and the ozone generator, so that when water exists in the clothes treatment barrel, the ozone, the catalyst and the water can be mixed with each other to react to generate hydroxyl radicals (-OH). The hydroxyl free radical can participate in sterilization, and the sterilization effect is improved. Preliminary experiment results show that the concentration of the generated-OH can be controlled to be 0.12-0.32 mM, and the sterilization rate can reach more than 99%. That is to say, among this technical scheme, not only there is ozone to disinfect, and hydroxyl radical participates in the sterilization in addition, is favorable to promoting this clothing processing apparatus's bactericidal effect by a wide margin. In addition, the catalyst cavity is additionally arranged to contain the catalyst, and the hydroxyl radicals are generated to participate in sterilization, so that the water in the clothes treatment drum can achieve the sterilization effect even at low temperature, namely the water does not need to be heated, and the cold water can achieve the sterilization purpose.

It is understood that hydroxyl radicals are an important active oxygen. The hydroxyl free radical has extremely high oxidation potential (2.80eV), has extremely strong oxidation capacity, can generate rapid chain reaction with most organic pollutants, and can indiscriminately oxidize harmful substances into CO₂、H₂O or mineral salt, and no secondary pollution. That is, compared with ozone, hydroxyl radicals not only have stronger sterilization effect, but also have stronger decontamination capability, and have no secondary pollution, and a device for removing redundant hydroxyl radicals subsequently is not needed, so that the structure can be simpler than that of ozone decontamination sterilization.

The hydroxyl radical can be generated in various ways, and in addition to the catalyst generation method adopted in the above technical means, there are electrolytic oxidation method, semiconductor electrocatalysis method, and the like. In the technical scheme, a catalyst generation mode is adopted, only one catalyst cavity needs to be added, and compared with an electrolytic oxidation mode, a semiconductor electro-catalysis method and the like, the catalyst cavity has the advantages of simpler structure, easiness in production and installation, convenience in operation and maintenance and easiness in control. In addition, only a catalyst cavity needs to be added, so that the volume is small, the occupied space is small, the existing idle space of the clothes treatment device can be utilized, the change of the existing structure is small, the application range is wide, and the application on various clothes treatment devices is facilitated.

It should also be noted that the hydroxyl radical also has the function of preventing the color of clothes from mixing, so that clothes with various colors can be shuffled, thereby saving a great amount of time, electric power and water resources for users, providing greater convenience for the users to use the clothes treatment device, and being beneficial to improving the life quality of the users.

Specifically, by providing an ozone generator, ozone can be generated. Ozone can be used for sterilization, and is used for forming hydroxyl free radicals by mixing with a catalyst and water, and the hydroxyl free radicals and the ozone sterilize together, so that the sterilization effect is improved. Specifically, when the water level in the laundry treatment drum reaches the height of the catalyst cavity, ozone is dissolved in water and further mixed with the catalyst in the catalyst cavity to form mixed water containing ozone and hydroxyl radicals, thereby sterilizing the laundry in the laundry treatment drum.

By arranging the air pump, the air pump is connected with the ozone generator, and the ozone generator is connected with the catalyst cavity, so that the air pump can drive the ozone generated by the ozone generator to flow into the catalyst cavity without arranging a Venturi valve and other negative pressure devices. The pressure of the air pump is adjusted, the quantity of ozone conveyed can be adjusted, the concentration of ozone in water is adjusted, the concentration of hydroxyl radicals is adjusted, and the purpose that the concentration of ozone and the concentration of hydroxyl radicals are controllable is achieved. In addition, the gas is blown into the washing machine by the gas pump, so that the dissolving speed of the detergent can be increased, and the preliminary experiment result shows that the washing mode of blowing gas into the washing machine by the gas pump is increased by about 2 times compared with the detergent dissolving speed in normal washing.

Furthermore, the air pump is arranged to form positive pressure on the side of the ozone generator, so that water in the clothes treatment drum can be prevented from flowing back to the ozone generator, namely, the air pump can also play a role in limiting the water flow direction, and therefore, the one-way valve can be replaced. In addition, because the ozone generator is in positive pressure, fine objects such as flocks and the like in the clothes treatment cylinder are not easy to enter the ozone generator or enter the ozone conveying pipeline. Even if fine objects such as flocks and the like enter the ozone conveying pipeline, the objects blocking the conveying pipeline can be blown out by the pressure of the air pump, so that the smoothness of the ozone conveying pipeline is ensured. It should also be noted that, since no venturi valve is required, the pipe can be made relatively wider, i.e. the flow passage can be made more loose and less prone to clogging. In conclusion, the air pump has the advantages that the air pump not only plays a role in driving ozone, replaces a Venturi valve, but also can limit the water flow direction, plays a role in a one-way valve, and can be used for dredging when a conveying pipeline is blocked. Therefore, the air pump mode is adopted, the number of parts is reduced, and the structure and the control mode are simplified.

It should also be noted that when there is no water in the laundry treatment drum, i.e. no laundry is washed, ozone may be delivered into the laundry treatment drum by the air pump to sterilize the laundry treatment drum or the laundry therein. Compared with the clothes treatment device adopting a negative pressure device such as a Venturi valve, the ozone conveying does not need to depend on the negative pressure generated by water flow, so that the ozone conveying is more flexible, the objects of disinfection and sterilization are not limited to the clothes in washing, and can be a clothes treatment drum and the dried clothes, and the convenience and the flexibility of the use of the clothes treatment device are improved.

The arrangement of the air pump is also beneficial to generating bubbles in water. The bubbles are broken under the rotation action of the clothes treatment drum to form impact force, so that the decontamination and sterilization capacity of the detergent, ozone water and hydroxyl free radicals is stronger, and the clothes treatment device realizes the effects of disinfection and sterilization and improvement of the cleanliness.

In the technical scheme, a drainage component is arranged on the clothes treatment barrel and is communicated with an inner cavity of the clothes treatment barrel; the catalyst chamber is in communication with the drain assembly.

In this embodiment, the catalyst chamber is in communication with the drain assembly, it being understood that the drain assembly is generally disposed at a lower location on the laundry treating drum, and that the drain assembly will generally have water whenever washing is performed. Correspondingly, the catalyst cavity communicated with the drainage component has greater possibility of contacting with water, thereby creating conditions for the generation of ozone dissolved in water and hydroxyl free radicals and achieving the purpose of double sterilization of ozone and hydroxyl free radicals. The water drainage component is communicated with the inner cavity of the clothes treatment barrel, so that water in the inner cavity can be conveniently discharged.

Therefore, even if only a small amount of water is in the clothes treatment drum, the water in the water discharging component can be basically ensured, and the water can be correspondingly supplied to the catalyst cavity, so that the purposes that the ozone is dissolved in the water and reacts with the catalyst to generate the hydroxyl radicals are achieved. And when water is fed, the drainage assembly and the catalyst cavity are positioned at the bottom of the clothes treatment drum, so that the catalyst and the ozone can contact the water at the beginning. In the drainage process, water can be kept in the catalyst cavity until the drainage is finished, namely, in the whole washing process, water is in contact with the catalyst and ozone in the catalyst cavity, so that the reaction time is prolonged, the content or concentration of ozone and hydroxyl radicals in water in the clothes treatment drum is increased, and the sterilization effect is improved.

In the technical scheme, the clothes treatment barrel comprises an outer barrel and an inner barrel, the outer barrel is sleeved on the inner barrel, and the catalyst cavity is arranged between the outer barrel and the inner barrel.

The axial direction of the catalyst cavity is arranged along the direction from the top to the bottom of the clothes treatment drum, so that the catalyst cavity is convenient to adapt to the shape of the inner space of the clothes treatment device, and a larger volume is provided for the catalyst in a limited space.

In any of the above technical solutions, the axial dimension of the catalyst cavity is smaller than or equal to the radial dimension of the catalyst cavity.

In the technical scheme, the power of the ozone generator is adjusted by arranging the controller, so that the supply amount of ozone can be adjusted, and further the concentration of ozone and the concentration of hydroxyl radicals in water are adjusted. It can be understood that after the controller is arranged, the ozone concentration in the water can be adjusted by adjusting the power of the ozone generator and adjusting the ozone conveying speed through the air pump, so that the flexibility of ozone concentration adjustment is improved.

In any of the above technical solutions, a baffle is disposed in the catalyst chamber, and the baffle is disposed on a sidewall of the catalyst chamber and extends from the sidewall to the catalyst chamber.

Detailed Description

In order that the above objects, features and advantages of embodiments according to the present application may be more clearly understood, embodiments according to the present application will be described in further detail below with reference to the accompanying drawings and detailed description. It should be noted that features of embodiments according to the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth to provide a thorough understanding of embodiments according to the present application, however, embodiments according to the present application may be practiced in other ways than those described herein, and therefore the scope of protection afforded by embodiments according to the present application is not limited by the specific embodiments disclosed below.

Some embodiments provided in accordance with the present application are described below with reference to fig. 1-5.

Example 1

As shown in fig. 1 to 5, according to one embodiment of the present application, there is provided a laundry treating apparatus 10 including an ozone generator 100, an air pump 102, a laundry treating drum 104, and a catalyst chamber 106.

Specifically, the ozone generator 100 is used to generate ozone. An air pump 102 is connected to the ozone generator 100 and is used to drive the ozone. The catalyst chamber 106 is in communication with the laundry treatment drum 104, while the catalyst chamber 106 is also in communication with the ozone generator 100. The catalyst chamber 106 is used for containing a catalyst, so that when the laundry processing drum 104 is filled with water during washing laundry, the catalyst can chemically react with ozone and water to generate hydroxyl radicals.

In this embodiment, catalyst chamber 106 is in communication with laundry treatment drum 104, and catalyst chamber 106 is also in communication with ozone generator 100, such that when water is present in laundry treatment drum 104, the three components, ozone, catalyst and water, may mix and react with each other to generate hydroxyl radicals (-OH). The hydroxyl free radical can participate in sterilization, and the sterilization effect is improved. Preliminary experiment results show that the concentration of the generated-OH can be controlled to be 0.12-0.32 mM, and the sterilization rate can reach more than 99%. That is, in this embodiment, not only ozone sterilization but also hydroxyl radicals participate in sterilization, which is beneficial to greatly improve the sterilization effect of the laundry processing apparatus 10. In addition, by adding the catalyst chamber 106 to contain the catalyst and generate hydroxyl radicals to participate in sterilization, the water in the laundry treatment drum 104 can achieve sterilization effect even at low temperature, that is, the cold water can achieve sterilization without heating the water.

It is understood that hydroxyl radicals are an important active oxygen. Hydroxyl radical, oxygen of which has an extremely high oxidation potential (2.80eV)Has strong chemical ability, can generate rapid chain reaction with most organic pollutants, and can oxidize harmful substances into CO without selectivity₂、H₂O or mineral salt, and no secondary pollution. That is, compared with ozone, hydroxyl radicals not only have stronger sterilization effect, but also have stronger decontamination capability, and have no secondary pollution, and a device for removing redundant hydroxyl radicals subsequently is not needed, so that the structure can be simpler than that of ozone decontamination sterilization.

The hydroxyl radical can be generated in various ways, and in addition to the catalyst generation method used in this example, there are an electrolytic oxidation method, a semiconductor electrocatalytic method, and the like. In this embodiment, the catalyst generation mode is adopted, and only one catalyst chamber 106 needs to be added, so that compared with an electrolytic oxidation mode, a semiconductor electro-catalysis method and the like, the catalyst generation mode is simpler in structure, easy to produce and install, convenient to operate and maintain and easy to control. In addition, only the catalyst cavity 106 needs to be added, so that the size is small, the occupied space is small, the existing idle space of the clothes treatment device 10 can be utilized, the change on the existing structure is small, the application range is wide, and the application on various clothes treatment devices 10 is facilitated.

It should be noted that the hydroxyl radicals also have the function of preventing the color of clothes from being mixed, so that clothes with various colors can be shuffled, thereby saving a great amount of time, power and water resources for users, providing greater convenience for the users to use the clothes treatment device 10, and being beneficial to improving the life quality of the users.

Specifically, by providing the ozone generator 100, ozone can be generated. Ozone can be used for sterilization, and is used for forming hydroxyl free radicals by mixing with a catalyst and water, and the hydroxyl free radicals and the ozone sterilize together, so that the sterilization effect is improved. Specifically, when the water level in the laundry treatment drum 104 reaches a level in the catalyst cavity 106 at which the ozone can directly contact the catalyst, the ozone is dissolved in the water and further mixed with the catalyst in the catalyst cavity 106 to form mixed water containing ozone and hydroxyl radicals, thereby sterilizing the laundry in the laundry treatment drum 104.

By arranging the air pump 102, the air pump 102 is connected with the ozone generator 100, and the ozone generator 100 is connected with the catalyst cavity 106, so that the air pump 102 can drive the ozone generated by the ozone generator 100 to flow into the catalyst cavity 106, and negative pressure devices such as a Venturi valve and the like do not need to be arranged. The pressure of the air pump 102 can be adjusted, and the quantity of ozone conveyed can be adjusted, so that the concentration of ozone in water and the concentration of hydroxyl radicals can be adjusted, and the purpose of controlling the concentration of ozone and the concentration of hydroxyl radicals can be achieved. In addition, the gas is blown into the gas pump 102, so that the dissolving speed of the detergent can be increased, and the preliminary experiment result shows that the washing mode of blowing gas into the gas pump 102 is improved by about 2 times compared with the detergent dissolving speed in normal washing.

Further, by setting the air pump 102, a positive pressure is formed on the side of the ozone generator 100, so that the water in the laundry drum 104 can be prevented from flowing back into the ozone generator 100, that is, the air pump 102 can also function to restrict the direction of the water flow, thereby replacing the check valve. In addition, since the ozone generator 100 is positively pressurized, fine objects such as lint in the laundry drum 104 are not easily introduced into the ozone generator 100 or into the ozone transfer duct. Even if fine objects such as flocks and the like enter the ozone conveying pipeline, the objects blocking the conveying pipeline can be blown out by the pressure of the air pump 102, so that the smoothness of the ozone conveying pipeline is ensured. It should also be noted that, since no venturi valve is required, the pipe can be made relatively wider, i.e. the flow passage can be made more loose and less prone to clogging. In conclusion, the air pump 102 not only has the function of driving ozone, replaces a Venturi valve, but also can limit the water flow direction, has the function of a one-way valve, and can be dredged when a conveying pipeline is blocked. Therefore, the air pump 102 is adopted, so that the number of parts is reduced, and the structure and the control mode are simplified.

It should also be noted that when there is no water in the laundry treatment drum 104, i.e. no laundry is washed, ozone may be delivered into the laundry treatment drum 104 by the air pump 102 to sterilize the laundry treatment drum 104 or the laundry therein. Compared with the clothes treatment device 10 adopting a negative pressure device such as a Venturi valve, the ozone conveying does not need to depend on the negative pressure generated by water flow, so that the ozone conveying is more flexible, the objects of disinfection and sterilization are not limited to the clothes in washing, but also the clothes treatment drum 104 and the dried clothes, and the convenience and the flexibility of the use of the clothes treatment device 10 are improved.

If the clothes treatment device 10 is a washing and drying integrated machine, in the drying process, due to the existence of condensed water, ozone can be dissolved in the condensed water and discharged, and the diffusion of sewer odor is reduced.

The air pump 102 is also arranged to facilitate the generation of air bubbles in the water. The bubbles are broken under the rotation of the laundry treatment drum 104 to form an impact force, so that the detergent, ozone water and hydroxyl radical have stronger decontamination and sterilization capabilities, and the laundry treatment device 10 realizes the effects of disinfection and sterilization and improvement of cleanliness.

Example 2

As shown in fig. 2 and 4, specifically, the ozone generator 100 is used to generate ozone. An air pump 102 is connected to the ozone generator 100 and is used to drive the ozone. The bottom of the laundry treatment drum 104 is provided with a drain assembly 108, and the drain assembly 108 is communicated with the inner cavity of the laundry treatment drum 104. A catalyst chamber 106 is also provided at the bottom of the laundry treating drum 104 and communicates with a drain assembly 108. At the same time, catalyst chamber 106 is also in communication with ozone generator 100. The catalyst chamber 106 is used for containing a catalyst, so that when the laundry processing drum 104 is filled with water during washing laundry, the catalyst can chemically react with ozone and water to generate hydroxyl radicals.

Specifically, by providing the ozone generator 100, ozone can be generated. Ozone can be used for sterilization, and is used for forming hydroxyl free radicals by mixing with a catalyst and water, and the hydroxyl free radicals and the ozone sterilize together, so that the sterilization effect is improved. Specifically, since the drainage assembly 108 and the catalyst chamber 106 are both disposed at the bottom of the laundry treatment drum 104, as long as there is water in the laundry treatment drum 104, the water can easily submerge the catalyst chamber 106, so that the ozone is dissolved in the water and further mixed with the catalyst in the catalyst chamber 106 to form mixed water containing ozone and hydroxyl radicals, thereby sterilizing the laundry in the laundry treatment drum 104.

Both the drain assembly 108 and the catalyst chamber 106 are provided at the bottom of the laundry treatment drum 104, i.e. both are located at the lower water level of the laundry treatment drum 104. This substantially ensures that the drain assembly 108 has water even if there is a small amount of water in the laundry drum 104, and accordingly supplies water to the catalyst chamber 106, thereby achieving the goal of ozone dissolving in water and reacting with the catalyst to generate hydroxyl radicals. Furthermore, when water is supplied, the drain assembly 108 and the catalyst chamber 106 are located at the bottom of the laundry treatment drum 104, so that the catalyst, ozone, can contact the water at the beginning. In the draining process, water can be kept in the catalyst cavity 106 until the draining is finished, that is, in the whole washing process, water in the catalyst cavity 106 is contacted with the catalyst and ozone, so that the reaction time is prolonged, the content or concentration of ozone and hydroxyl radicals in the water in the clothes treatment drum 104 is increased, and the sterilizing effect is improved.

The clothes treating drum 104 includes an outer drum and an inner drum, the outer drum is sleeved on the inner drum, and the catalyst chamber 106 is arranged between the outer drum and the inner drum.

In this embodiment, the catalyst chamber 106 is disposed between the outer cylinder and the inner cylinder, and the gap between the outer cylinder and the inner cylinder is utilized, so that the space occupation is small, the existing structure is slightly changed, and the production is convenient.

The hydroxyl free radical can participate in sterilization, and the sterilization effect is improved. Preliminary experiment results show that the concentration of the generated-OH can be controlled to be 0.12-0.32 mM, and the sterilization rate can reach more than 99%. That is, in this embodiment, not only ozone sterilization but also hydroxyl radicals participate in sterilization, which is beneficial to greatly improve the sterilization effect of the laundry treatment apparatus 10, and cold water can achieve the purpose of sterilization even at low temperature.

Example 4

As shown in fig. 1 and 3, according to still another embodiment of the present application, there is provided a laundry treating apparatus 10 including an ozone generator 100, an air pump 102, a laundry treating drum 104, and a catalyst chamber 106. The air pump 102 and ozone generator 100 are disposed at the top of the laundry drum 104, and the catalyst chamber 106 is disposed at the bottom of the laundry drum 104.

In this embodiment, the air pump 102 and ozone generator 100 are located at the top of the laundry treatment drum 104, i.e. the ozone generator 100 is located at a higher position of the laundry treatment drum 104 during use of the apparatus. Meanwhile, the catalyst cavity 106 is arranged at the bottom of the clothes treatment drum 104, and under the dual action of the pressure and gravity of the air pump 102, water flow is difficult to flow back into the ozone generator 100, and accordingly, objects such as flocks and the like are difficult to enter a conveying pipeline of the ozone generator 100 to cause blockage, so that the stability and the reliability of the use of the clothes treatment device 10 are improved.

Further, the air pump 102 and the ozone generator 100 are integrally arranged, so that production and assembly links are reduced, production efficiency is improved, and assembly difficulty is reduced. The integrated arrangement of the air pump 102 and the ozone generator 100 is also beneficial to reducing the volume and saving the space.

In this embodiment, catalyst chamber 106 is in communication with laundry treatment drum 104, and catalyst chamber 106 is also in communication with ozone generator 100, such that when water is present in laundry treatment drum 104, the three components, ozone, catalyst and water, may mix and react with each other to generate hydroxyl radicals (-OH).

The air pump 102 can also form positive pressure on one side of the ozone generator 100 to prevent water in the clothes treatment drum 104 from flowing back into the ozone generator 100, that is, the air pump 102 can also play a role in limiting the water flow direction, thereby replacing a one-way valve. Therefore, the air pump 102 is adopted, so that the number of parts is reduced, and the structure and the control mode are simplified.

In any of the above embodiments, as shown in fig. 1 and 2, the axial dimension of the catalyst chamber 106 is greater than the radial dimension of the catalyst chamber 106, and the axial direction of the catalyst chamber 106 is arranged in the top-to-bottom direction of the laundry treatment drum 104. This results in a generally elongated catalyst chamber 106, which advantageously increases the volume and length of catalyst chamber 106. Through the increase of volume, length, can increase the quantity of catalyst to increase the dwell time of ozone in catalyst chamber 106, thereby increase the reaction time of ozone, water, catalyst three, be favorable to promoting hydroxyl radical's quantity and concentration. The axial direction of the catalyst chamber 106 is arranged along the top-to-bottom direction of the laundry treating drum 104, so as to be adapted to the shape of the inner space of the laundry treating apparatus 10, providing a larger volume for the catalyst in a limited space.

Example 7

As shown in fig. 3 and 4, unlike embodiment 6, the axial dimension of the catalyst chamber 106 in this embodiment is equal to or smaller than the radial dimension of the catalyst chamber 106.

In this embodiment, by setting the axial dimension of the catalyst chamber 106 to be equal to or less than the radial dimension of the catalyst chamber 106, i.e. the catalyst chamber 106 is substantially spherical or flat, it is beneficial to adapt to some special spaces in the laundry treating apparatus 10, and improve the space utilization in the laundry treating apparatus 10.

Example 8

In any of the above embodiments, the relative position between the ozone generator 100 and the catalyst cavity 106 can be flexibly set according to the position of the water inlet relative to the clothes treatment device, and it can be understood that the ozone generator 100 is used for providing ozone, mixing the ozone and water, and flowing into the catalyst cavity 106 for catalytic reaction, the ozone generator 100 and the catalyst cavity 106 can be set up and down, as shown in fig. 1, the catalyst cavity 106 is located below, the ozone generator 100 is located above, when the water flows to the catalyst cavity 106 after passing through the ozone generator 100 from top to bottom, the water surface of the water flow will not pass through the catalyst cavity 106, the catalysis of the ozone is more sufficient, and the sterilization effect is improved.

Alternatively, the catalyst chamber 106 may be disposed above and the ozone generator 100 may be disposed below, and at this time, the water flow sequentially flows through the ozone generator 100 and the catalyst chamber 106 from bottom to top, which is more suitable for a clothes treatment apparatus of a lower water inlet type.

It can be understood that there is a certain distance between the ozone generator 100 and the catalyst cavity 106, in order to realize the normal flow of water flow and to prevent the ozone from overflowing, the ozone generator 100 and the catalyst cavity 106 can be connected by a sealed pipeline, of course, in the case of providing the split air pump 102, the air pump 102 can be connected with the ozone generator 100 by a sealed pipeline, and if the air pump 102 and the ozone generator 100 are designed integrally, no additional pipeline is needed to connect the two.

Furthermore, in any of the above embodiments, the laundry treatment apparatus 10 further comprises a controller (not shown) connected to the ozone generator 100, the controller being configured to adjust the power of the ozone generator 100.

In this embodiment, the power of the ozone generator 100 is adjusted by setting a controller, so that the supply amount of ozone can be adjusted, and the concentration of ozone and the concentration of hydroxyl radicals in water can be adjusted. It can be understood that after the controller is set, the adjustment of the ozone concentration in the water can be realized by adjusting the power of the ozone generator 100 or by adjusting the ozone delivery speed through the air pump 102, thereby improving the flexibility of the adjustment of the ozone concentration.

Example 9

As shown in fig. 1, according to still another embodiment of the present application, there is provided a laundry treating apparatus 10 including an ozone generator 100, an air pump 102, a laundry treating drum 104, and a catalyst chamber 106.

Specifically, the ozone generator 100 is used to generate ozone. An air pump 102 is connected to the ozone generator 100 and is used to drive the ozone. The bottom of the laundry treatment drum 104 is provided with a drain assembly 108, and the drain assembly 108 is communicated with the inner cavity of the laundry treatment drum 104. A catalyst chamber 106 is also provided at the bottom of the laundry treating drum 104 and communicates with a drain assembly 108. At the same time, catalyst chamber 106 is also in communication with ozone generator 100. The catalyst chamber 106 is used for containing a catalyst, so that when the laundry processing drum 104 is filled with water during washing laundry, the catalyst can chemically react with ozone and water to generate hydroxyl radicals.

The hydroxyl free radical can participate in sterilization, and the sterilization effect is improved.

As shown in fig. 5, to increase the hydroxyl radical content, a baffle 1060 for blocking water flow is provided in the catalyst chamber 106. The baffle 1060 is disposed on the sidewall 1062 of the catalyst chamber 106 and extends from the sidewall 1062 into the catalyst chamber 106. The baffle 1060 can effectively prolong the stay time of the water flow in the catalyst cavity 106 by blocking the water flow, so that the reaction time of ozone water and the catalyst is prolonged, the generation quantity of hydroxyl radicals is increased, and the sterilization effect of the water flow is improved.

It should be noted that the baffle 1060 is disposed on the side wall 1062 of the catalyst cavity 106 and extends toward the side wall 1062 into the catalyst cavity 106, that is, the baffle 1060 does not extend from one side wall 1062 to the other side wall 1062, but has a certain gap with the other side wall 1062, so that it is ensured that the water flow can be blocked for a while and can circulate, so as to bring out the mixed water with ozone and hydroxyl radicals into the laundry treatment drum 104, and sterilize the laundry.

As shown in fig. 5, further, the number of the baffles 1060 is plural. The plurality of baffles 1060 are arranged at intervals. This allows multiple dampings of the water flow by multiple baffles 1060. Through stopping many times, can further delay the velocity of water flow, increase the reaction of ozone water and catalyst and be long, promote the production quantity of hydroxyl free radical to promote the bactericidal effect of rivers.

Further, on the two opposing side walls 1062 of the catalyst chamber 106, a plurality of baffles 1060 are alternately arranged so as to form a meandering flow path, more effectively extending the length of the water flow path in the catalyst chamber 106 and increasing the length of time the water flow passes through the catalyst chamber 106. Accordingly, the time of the water flow flowing through the catalyst cavity 106 is increased, and the reaction time of the ozone water and the catalyst is further increased, which is beneficial to further increasing the content of the hydroxyl radicals in the water flow, thereby improving the sterilization effect of the water flow.

Example 10

In any of the above embodiments, the laundry treating apparatus 10 is a washing and drying machine. In washing laundry, the laundry is sterilized by ozone and hydroxyl radicals. Sterilization may be performed only by ozone when drying laundry. When washing and drying are not required, the laundry treatment drum 104 can be independently sterilized by ozone without depending on the water flow.

It can be understood that when the clothes are dried, attention needs to be paid to control the temperature, and the phenomenon that ozone is directly decomposed due to overhigh temperature and the sterilization effect is lost is avoided.

In other embodiments, the laundry treatment apparatus 10 is a drum washing machine or a pulsator washing machine, and performs sterilization by ozone and hydroxyl radicals during water intake washing, and has a simple structure, is convenient to control, and the concentration of ozone and the concentration of hydroxyl radicals can be adjusted.

Example 11

As shown in fig. 1, the washing and drying integrated machine according to an embodiment of the present application carries an ozone catalytic oxidation technology. The washing and drying all-in-one machine comprises an air pump 102 and an ozone generator 100 which are arranged on the top of the outer barrel, and a catalyst cavity 106 (filled with granular catalyst) filled with catalyst at the water outlet end. Under the condition that the water inlet mode of the original washing and drying integrated machine is not changed, a catalyst cavity 106 with one end filled with catalyst is additionally arranged at the original water outlet pipe. The air pump 102 is connected to the air inlet of the ozone generator 100, and the air outlet of the ozone generator 100 is connected to the catalyst chamber 106.

During washing, after the washing and drying integrated machine normally enters water, the water surface submerges the catalyst cavity 106, so that the catalyst in the washing and drying integrated machine is completely immersed in the water, air is blown into the ozone generator 100 by the air pump 102 to generate ozone, then the ozone enters the catalyst cavity 106, and the ozone reacts with the water through the catalyst to generate hydroxyl radicals (-OH) which enter the inner cylinder for washing. During drying, air blown by the air pump 102 enters the ozone generator 100 to generate ozone, the ozone passes through the catalyst cavity 106, no water is stored in the catalyst cavity 106, and the ozone directly enters the inner cylinder to be dried and sterilized.

The principle of the washing and drying integrated machine of the application is as follows:

a washing and drying integrated machine is provided with an ozone catalytic oxidation technology. As shown in FIG. 1, air is blown through the air pump 102 to cause the ozone generator 100 to generate ozone, which reacts with the catalyst in the catalyst chamber 106 to generate-OH (O3+ H2O + catalyst → 2-OH + O2).

The present embodiment can improve the problem:

1. in washing, the detergent dissolution rate can be increased due to the gas blown by the gas pump 102. Preliminary experiment results show that the dissolution speed of the air-blowing washing agent is improved by about 2 times compared with that of the normal washing detergent.

2. Because ozone and water generate-OH under the action of a catalyst, ozone and hydroxyl free radicals play an oxidizing role in water. The hydroxyl free radicals can sterilize and prevent the color of clothes from being mixed. In addition, the concentration of ozone can be controlled by changing the power of the ozone generator 100, and the amount of catalyst used can be adjusted to control the concentration of ozone and-OH during washing. Preliminary experiment results show that the concentration of the generated-OH can be controlled to be 0.12-0.32 mM, and the sterilization rate can reach more than 99%.

3. During drying, because the catalyst cavity 106 is not filled with water, the ozone generated by the air pump 102 and the ozone generator 100 directly enters the inner cylinder, and is disinfected and sterilized during drying. In addition, due to the existence of condensed water in the drying process, ozone can be dissolved in the condensed water and flows into a sewer, and the peculiar smell diffusion of the sewer is reduced.

4. The device does not need to be additionally provided with redundant control valves, is easy to operate, and is simpler in structure compared with other-OH generating devices.

5. The washing and drying integrated machine of the embodiment realizes water-gas integrated sterilization, can perform sterilization and color cross prevention by using-OH in water, and can perform sterilization on the integrated machine and clothes by using ozone during drying.

In other embodiments, the catalyst chamber 106 can also be disposed in a groove between the outer cylinder and the inner cylinder, or in a gap between the outer cylinder and the inner cylinder, and an opening is additionally disposed to communicate the ozone generator 100 and the catalyst chamber 106.

In other embodiments, the catalyst cavity 106 may also be disposed in a groove between the outer cylinder and the inner cylinder, or in a gap between the outer cylinder and the inner cylinder, and the ozone generator 100 may be communicated with an opening of the outer cylinder, or the ozone generator 100 may be connected 108 to the water outlet.

In still other embodiments, the ozone generator 100 and the air pump 102 can be made as an integral module, reducing the volume occupied.

The embodiments provided in the present application are described in detail with reference to the accompanying drawings, and according to the embodiments, ozone and hydroxyl radicals can be simultaneously used for sterilization during a washing process, ozone gas can be separately used for sterilization during a drying process, and in addition, detergent dissolution, cold water sterilization, prevention of color contamination of clothes, and the like can be accelerated.
