Description

Technical Field

[0001] The present application relates to the technical field of ozone care, and in particular, to an ozone care method, a control device and a clothing treatment device. Background Art

[0002] In the process of clothing treatment equipment using ozone to sterilize or deodorize clothing, ozone is generally introduced into the clothing at a certain stage or multiple stages of the clothing treatment or throughout the entire process. There is no limit on the rhythm of ozone introduction, and the introduction of ozone throughout the entire process will cause the ozone concentration to continue to increase, which is prone to the risk of ozone leakage and will also increase the ozone degradation time.

[0003] In the related art, when using ozone to care for clothes, ozone is generally introduced at intervals or periodically during the drying or cooling stage of the clothes, or by monitoring the ozone concentration in the drum to control the introduction of ozone. However, when ozone is introduced at fixed time intervals, the ozone concentration in the drum will fluctuate as the environmental parameters in the drum change; and the ozone concentration detected by the detection device deviates from the actual ozone concentration, which also causes the ozone concentration in the drum to fluctuate. Therefore, the above two methods of ozone introduction will cause the ozone concentration in the drum to fluctuate, affecting the treatment effect of ozone on clothes. Summary of the invention

DETAILED DESCRIPTION

[0058] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the implementation mode of the present application. Obviously, the described implementation mode is only a part of the implementation mode of the present application, not all the implementation modes. Based on the implementation mode in the present application, all other implementation modes obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0059] It should be understood that the "plurality" mentioned herein refers to two or more than two. In the description of the implementation modes of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solutions of the implementation modes of the present application, in the implementation modes of the present application, the words "first", "second" and the like are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second" and the like do not limit the quantity and execution order, and the words "first", "second" and the like do not limit certain different

[0060] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0061] In real life, users are prone to various odors, such as smoke, sweat, hot pot, snail noodle, etc. In related technologies, washing machines are combined with nano-photocatalytic technology to use light of a specific wavelength to excite nano-photocatalysts to remove odors from clothes in washing machines. However, this simple use of nano-photocatalytic technology to remove odors from clothes cannot completely remove odors from clothes.

[0062] In the related art, clothing treatment equipment with ozone care function, in the process of using ozone to care for clothing, usually introduces a predetermined amount of ozone at a predetermined injection interval and monitors the ozone concentration in real time. Since a single interval or periodic introduction of ozone cannot cope with the impact of different clothing treatment states (such as high temperature, blowing, steam, etc.) on ozone concentration, there is a large difference in ozone concentration under different clothing treatment states. In addition, due to the large size of the detection instrument and its susceptibility to damage by harsh environments (high temperature and high humidity), the detection device is generally not installed in the outer drum, resulting in a deviation between the ozone concentration detected by the detection device and the actual ozone concentration in the actual drum. In addition, the detection result of the detection instrument has a delay, which also leads to a deviation between the detected ozone concentration and the actual ozone concentration, resulting in a problem of large fluctuations in ozone concentration.

[0063] In order to solve the technical problems in the related art, the embodiment of the present application provides an ozone care method, which includes:

[0064] determining a target ozone introduction rhythm according to at least a current laundry treatment stage of the laundry treatment device;

[0065] During the laundry treatment stage, the laundry treatment equipment is controlled to control ozone introduction at a target introduction rhythm.

[0066] According to the implementation mode of the present application, by adopting different ozone introduction rhythms in different clothing treatment stages, the ozone introduction rhythm is adapted to the internal environment of the drum in the current clothing treatment stage, and the ozone concentration in the drum fluctuates less in different clothing treatment stages. During the ozone care process, the ozone concentration in the clothing treatment drum is always maintained at a relatively stable level, effectively ensuring the treatment effect of ozone on clothing. Moreover, during the ozone care process, there is no need to control the introduction of ozone by monitoring the ozone concentration in the clothing treatment drum, which effectively avoids the situation where the ozone concentration detected by the detection device is inconsistent with the actual ozone concentration and causes fluctuations in ozone concentration.

[0067] The technical solution of this embodiment is described in detail below in conjunction with the accompanying drawings. The following embodiments and examples can be combined with each other if there is no conflict.

[0068] First, the execution subject of the ozone care method of this embodiment is introduced. The ozone care method of this embodiment is applied to a clothing treatment device, such as a washing machine, a washer-dryer, a clothes dryer or a clothing care machine.

[0069] Figure 1 is a front cross-sectional view of the clothes processing device of this embodiment, Figure 2 2 is a cross-sectional side view of the laundry processing device of this embodiment. Figure 1 and Figure 2 The clothing treatment device comprises a housing 1, an outer drum and a clothing treatment drum 2, wherein the outer drum is arranged in the housing 1, and the clothing treatment drum 2 is rotatably arranged in the outer drum. The outer drum is also provided with a drain port, the drain port is connected to a drain pipe, and the drain pipe is provided with a drain pump 11.

[0070] The clothing treatment device further includes an ozone generating system, which includes an ozone generating device 5 and an air pump 4, wherein: the ozone generating device 5 and the air pump 4 are installed in the space between the housing 1 and the outer drum and are located at the bottom of the housing 1, and the ozone generating device 5 and the air pump 4 are connected by a hose. The ozone generating device 5 can be installed in front of the air pump 4 or behind the air pump 4. The ozone generating device 5 can be a ceramic sheet type ozone generating device 5, a tubular type ozone generating device 5 or an ultraviolet ozone generating device 5.

[0071] In one example, the ozone generator 5 is a ceramic sheet ozone generator 5, which includes a generating sheet 51 and a high-voltage power supply 52. ​​The generating sheet 51 is installed in a sealed box body (not shown in the figure), and the sealed box body can be cylindrical or rectangular. The high-voltage power supply 52 is arranged in the mounting shell 6, and the high-voltage power supply 52 outputs high voltage electricity to the generating sheet 51, and the generating sheet 51 generates high-voltage corona discharge to ionize the oxygen-containing air flowing through the generating sheet 51 and recombine to generate ozone.

[0072] The generating sheet 51 can be directly connected to the door seal 3 through the air outlet pipe 10, or the ozone generating system also includes a bubble generating device 8, and the generating sheet 51 is connected to the bubble generating device 8 through a connecting hose 9, and the connecting hose 9 is provided with a check valve 7. The ozone generated by the generating sheet 51 passes through the bubble generating device 8 and then is connected to the door seal 3 through the air outlet pipe 10, and the bubble generating device 8 can be used to generate foam containing ozone gas. The clothing processing equipment of this embodiment can open the bubble generating device 8 as needed, and when the bubble generating device 8 is turned on, when ozone passes through the bubble generating device 8, the bubble generating device 8 generates ozone-containing foam and enters the clothing processing tub 2 through the air outlet pipe 10, or when the bubble generating device 8 is closed, ozone can directly pass through the bubble generating device 8 and enter the clothing processing tub 2 through the air outlet pipe 10.

[0073] The working principle of the ozone generating system is as follows: the air pump 4 supplies oxygen-containing air to the generating sheet 51 of the ozone generating device 5, the generating sheet generates high-voltage corona discharge to generate ozone, and the ozone-containing gas passes through the bubble generating device 8 and then enters the clothing treatment drum 2 through the outlet pipe 10 connected to the door seal 3 to sterilize and deodorize the clothing.

[0074] The clothing processing apparatus further comprises a steam generating device 12 , which is disposed in the space between the outer drum and the shell 1 and located at the top of the shell 1 . The steam outlet of the steam generating device 12 is connected to the outer drum via a steam outlet pipe 15 .

[0075] The clothing processing device also includes a drying system, which includes a drying duct 14, a drying fan 13 and a heat pump system, and the heat pump system includes a refrigerant circulation loop formed by a compressor, a condenser, an electronic expansion valve and an evaporator. The outer cylinder includes an air inlet and an air outlet, the air inlet is arranged at the door seal 3, and the air outlet is arranged at the upper part of the outer cylinder. The drying duct 14 includes an air inlet duct and an air outlet duct, the air inlet duct connects the air outlet of the outer cylinder with the air inlet end of the drying fan 13, and the air outlet duct connects the air inlet of the outer cylinder with the air outlet end of the drying fan 13.

[0076] The ozone care method of this embodiment can be executed in a separate ozone care program or embedded in a clothing treatment program, for example, the ozone care method of this embodiment can be executed during a steam care process or during a drying program.

[0077] Figure 3 This is one of the flow charts of the ozone care method provided in this embodiment, referring to Figure 3 , the ozone care method includes the following steps:

[0078] S31, at least according to the current clothing processing stage of the clothing processing device to determine the target ozone into the rhythm.

[0079] Specifically, the process of the ozone care method of this embodiment includes multiple clothing treatment stages, and different clothing treatment stages have different internal environments of the clothing treatment drum 2 to achieve different treatments of clothing. Before introducing ozone into the clothing treatment drum 2, the current clothing treatment stage of the clothing treatment device is first determined, and then the target introduction rhythm of ozone is determined according to the clothing treatment stage, so as to achieve the stability of the ozone concentration in the clothing treatment drum 2 under the internal environments of different clothing treatment drums 2 in different clothing treatment stages, thereby ensuring the treatment effect of ozone on clothing.

[0080] In this embodiment, the current clothing processing stage can be determined according to the accumulated running time of the clothing processing device during this startup, or according to the current clothing processing state of the clothing processing device.

[0081] In this embodiment, the target rhythm of ozone introduction can be determined only according to the current clothing treatment stage, and different clothing treatment stages correspond to different target rhythms of ozone introduction. In other achievable methods, the current clothing treatment stage can also be combined with other factors that can affect the ozone concentration to jointly determine the target rhythm of ozone introduction, for example, the current clothing treatment stage can be combined with the rotation parameters of the clothing treatment drum 2 to determine the target rhythm of ozone introduction, so as to improve the stability of ozone concentration and further ensure the treatment effect of ozone on clothing.

[0082] It should be noted that the current laundry processing stage may be the laundry processing stage that the laundry processing device is about to enter, or may be the laundry processing stage that the laundry processing device is currently operating.

[0083] S32. In the clothing treatment stage, the clothing treatment equipment is controlled to control ozone introduction at a target introduction rhythm.

[0084] Specifically, after determining the target ozone introduction rhythm in the clothing treatment stage, the ozone introduction is controlled by using the target introduction rhythm corresponding to the current clothing treatment stage, so that the ozone concentration in the clothing treatment drum 2 can be in a relatively stable state.

[0085] The ozone care method of this embodiment combines the ozone introduction rhythm with the clothing treatment stage of the clothing treatment device, so that the ozone introduction rhythm is adapted to the drum environment of the clothing treatment stage, and the ozone concentration in the clothing treatment drum 2 fluctuates less in different clothing treatment stages, and the ozone concentration is always maintained at a relatively stable level, effectively ensuring the treatment effect of ozone on clothing. In addition, this embodiment does not need to detect the ozone concentration in the clothing treatment drum 2 at all times, but only needs to adjust the ozone oxygenation rhythm to correspond to the current clothing treatment stage, avoiding the problem of large fluctuations in ozone concentration caused by the deviation between the ozone concentration detected by the detection device and the actual ozone concentration.

[0086] In some embodiments, determining a target ozone introduction rhythm at least according to a current laundry treatment stage of the laundry treatment device comprises the following steps:

[0087] S41, determining the initial ozone introduction rhythm according to the current clothing processing stage of the clothing processing equipment.

[0088] S42, optimizing the initial feeding rhythm according to the rotation parameters of the laundry processing drum 2 in the laundry processing stage to determine the target feeding rhythm.

[0089] Specifically, considering that the rotation parameters of the clothing treatment drum 2 also affect the distribution of ozone in the clothing treatment drum 2, and the rotation parameters of the clothing treatment drum 2 in different clothing treatment stages are not exactly the same. The ozone introduction rhythm of ozone in the clothing treatment stage is also combined with the rotation parameters of the clothing treatment drum 2. Therefore, before introducing ozone into the drum, the initial introduction rhythm of ozone corresponding to the current clothing treatment stage is first determined according to the clothing treatment stage in which the clothing treatment device is currently located, and then the initial introduction rhythm is optimized and adjusted according to the rotation parameters of the clothing treatment drum 2 corresponding to the current clothing treatment stage to determine the target introduction rhythm, so that the target introduction rhythm of ozone in the current clothing treatment stage is adapted to the clothing treatment state and the rotation parameters of the inner drum, so as to further improve the stability of the ozone concentration in the drum. Among them, the rotation parameters of the clothing treatment drum 2 include the rotation speed, direction and turn-stop ratio of the clothing treatment drum 2.

[0090] In some embodiments, the clothing processing equipment includes a steam generating device, a drying fan and a compressor. Different clothing processing stages correspond to different clothing processing states. The initial ozone introduction rhythm is determined according to the clothing processing stage of the clothing processing equipment, including: determining the clothing processing state according to the clothing processing stage, determining the initial ozone introduction rhythm according to the clothing processing state, and the clothing processing state includes the start-up state of the steam generating device 12, the start-up state of the drying fan 13 and the operating frequency of the compressor.

[0091] Specifically, the start-up state of the steam generating device 12, the start-up state of the drying fan 13 and the operating frequency of the compressor affect the diffusion and attenuation speed of ozone in the drum. For example, blowing low-temperature air into the drum helps the ozone to diffuse in the drum, which is beneficial to the increase of ozone concentration; passing steam into the clothing treatment drum 2 helps the dissolution and diffusion of ozone, which is beneficial to the increase of ozone concentration in the drum, but higher temperature steam will also accelerate ozone decay; and blowing high-temperature air into the drum will slow down the increase of ozone concentration in the drum and accelerate ozone decay. Therefore, different clothing treatment states in different clothing treatment stages will have different dispersion and attenuation effects of ozone.

[0092] In one example, considering that high-temperature steam is conducive to the dissolution and diffusion of ozone, the initial passage rhythm corresponding to the clothing treatment stage when the steam generator 12 is turned on can be made shorter than the initial passage rhythm corresponding to the clothing treatment stage when the steam generator 12 is turned off. Exemplarily, when the duration of stopping ozone passage in the initial passage rhythm is constant, the duration of ozone passage in the clothing treatment stage when the steam generator 12 is turned on can be set to be shorter than the duration of ozone passage in the clothing treatment stage when the steam generator 12 is turned off. Alternatively, when the duration of ozone passage in the initial passage rhythm is constant, the duration of stopping ozone passage in the clothing treatment stage when the steam generator 12 is turned on can be set to be longer than the duration of stopping ozone passage in the clothing treatment stage when the steam generator 12 is turned off.

[0093] Considering that blowing low-temperature air into the drum helps ozone diffuse in the drum and plays a favorable role in increasing the ozone concentration, the initial introduction rhythm corresponding to the clothing processing stage when the drying fan 13 is turned on can be made shorter than the initial introduction rhythm corresponding to the clothing processing stage when the drying fan 13 is turned off. Exemplarily, when the ozone-stopping duration of the initial introduction rhythm is constant, the ozone-stopping duration of the clothing processing stage when the drying fan 13 is turned on can be set to be shorter than the ozone-stopping duration of the clothing processing stage when the drying fan 13 is turned off. Alternatively, when the ozone-stopping duration of the initial introduction rhythm is constant, the ozone-stopping duration of the clothing processing stage when the drying fan 13 is turned on can be set to be longer than the ozone-stopping duration of the clothing processing stage when the drying fan 13 is turned off.

[0094] Considering that the high temperature in the barrel will slow down the rate of increase of the ozone concentration in the barrel, accelerate the decay of ozone, and accelerate the decomposition of ozone, and the higher the operating frequency of the compressor will lead to the higher temperature in the barrel, the initial introduction rhythm corresponding to the clothing treatment stage when the compressor is operated at the second frequency gear can be made greater than the initial introduction rhythm corresponding to the clothing treatment stage when the compressor is operated at the first frequency gear. Exemplarily, when the ozone-stopping duration of the initial introduction rhythm is constant, the ozone-stopping duration of the clothing treatment stage when the compressor is operated at the second frequency gear is set to be greater than the ozone-stopping duration of the clothing treatment stage when the compressor is operated at the first frequency gear. Alternatively, when the ozone-stopping duration of the initial introduction rhythm is constant, the ozone-stopping duration of the clothing treatment stage when the compressor is operated at the second frequency gear is set to be less than the ozone-stopping duration of the clothing treatment stage when the compressor is operated at the first frequency gear, and the frequency value of the first frequency gear is less than the frequency value of the second frequency gear. Exemplarily, the frequency gears of the compressor are low gear, middle gear and high gear, the first frequency gear is low gear, and the second frequency gear is high gear. For example, the frequency value of the first frequency gear is 25 Hz to 50 Hz, and the frequency value of the second frequency gear is 50 Hz to 75 Hz.

[0095] This embodiment determines the influence of the diffusion and decay of ozone in the clothing treatment drum 2 according to the conditions such as the steam generating device 12 spraying steam into the drum, the drying fan 13 blowing air into the drum, and the compressor heating the drum during the clothing treatment stage, and then formulates a suitable ozone introduction rhythm to reduce the fluctuation of ozone concentration in different clothing treatment stages and ensure the treatment effect of ozone on clothing.

[0096] In some embodiments, the clothing processing stage includes a first processing stage, a second processing stage, and a third processing stage. In the first processing stage, the steam generating device 12 and the drying fan 13 are both turned on, and the compressor operates at the first frequency gear. The first processing stage is, for example, a low-temperature air blowing steam burning stage. In the second processing stage, the steam generating device 12 is turned on, the drying fan 13 is turned off, and the compressor operates at the first frequency gear. The second processing stage is, for example, a steam spraying stage; in the third processing stage, the steam generating device 12 is turned off, the drying fan 13 is turned on, and the compressor operates at the second frequency gear. The third processing stage is, for example, a high-temperature air blowing drying stage.

[0097] The initial input rhythm corresponding to the first processing stage is R1, R1=R11 / R12; the initial input rhythm corresponding to the second processing stage is R2, R2=R21 / R22; the initial input rhythm corresponding to the third processing stage is R3, R3=R31 / R32; wherein: the frequency value of the first frequency gear is less than the frequency value of the second frequency gear; R11, R21 and R31 are the duration of ozone supply, R12, R22 and R32 are the duration of stopping ozone supply, R21<R11<R31, R32<R12<R22, and / or, R2<R1<R3.

[0098] Specific, combined Figure 5 According to the flow chart of the process, after entering the ozone care process (process S501), the control system will detect the states of the steam generating device 12, the drying fan 13, the compressor frequency, etc. (process S502), and determine whether the stage to be or currently running is the first processing stage (blowing low-temperature air to burn steam stage), the second processing stage (spraying steam stage) or the third processing stage (blowing high-temperature air to dry stage), etc., based on the detected states of the steam generating device 12, the drying fan 13, the compressor frequency, etc.

[0099] Specifically: if it is detected that the steam generating device 12 is turned on, the drying fan 13 is turned on, and the compressor is running at a lower first frequency gear, it is determined to be the first processing stage, and the initial ozone introduction rhythm is selected as R1 (process S511~S512); if it is detected that the steam generating device 12 is turned on, the drying fan 13 is turned off, and the compressor is running at a lower first frequency gear, it is determined to be the second processing stage, and the initial ozone introduction rhythm is selected as R2 (process S521~S522); if it is detected that the steam generating device 12 is turned off, the drying fan 13 is turned on, and the compressor is running at a higher second frequency gear, it is determined to be the third processing stage, and the initial ozone introduction rhythm is selected as R3 (process S531~S53). Among them: R1, R2, R3 are the ratios of the duration of ozone supply and the duration of ozone stop supply, that is, R1=R11 / R12, R2=R21 / R22, R3=R31 / R32, among which R11, R21, R31 are the duration of ozone supply, and R12, R22, R32 are the duration of ozone stop supply.

[0100] Since the effects of low-temperature wind, steam, and high-temperature hot wind on ozone are different, specifically, low-temperature wind helps ozone gas diffuse in the barrel, which is beneficial to the increase of ozone concentration in the barrel, but blowing also accelerates ozone decay to a certain extent; steam spraying can help ozone dissolve and diffuse, which is beneficial to the increase of ozone concentration in the barrel, but the higher temperature of steam will also accelerate ozone decay; and high-temperature hot wind will slow down the increase of ozone concentration in the barrel and accelerate ozone decay. Therefore, under the action of various conditions, the speed of increasing ozone concentration in the barrel is ranked from fast to slow: steam spraying is the fastest, blowing is the second, and blowing high-temperature hot air is the third; according to the speed of promoting ozone decomposition in the barrel, it is ranked from fast to slow: blowing high-temperature hot air is the fastest, blowing is the second, and steam spraying is relatively slow.

[0101] According to this rule, the initial ozone control rhythm can be formulated as follows: in the first treatment stage (low-temperature air blowing stage), the ozone passing time R11 is moderate, and the ozone stopping time R12 is moderate; in the second treatment stage (steam spraying stage), the ozone passing time R21 is shorter, and the ozone stopping time R22 is longer; in the second treatment stage (high-temperature hot air blowing stage), the ozone passing time R31 is longer, and the ozone stopping time R32 is shorter. For example, taking the cylinder volume as 85L and the output of the ozone generator 5 as 2000mg / H, the speed of the drying fan 13 is 2600R / min, the steam volume is 25-27g / min, and the target concentration in the cylinder is 10ppm, then the R11 time can be selected as 5-10 seconds, preferably 7 seconds, and the R12 time can be selected as 15-20 seconds, preferably 15 seconds; the R21 time can be selected as 3-8 seconds, preferably 5 seconds, and the R22 time can be selected as 16-22 seconds, preferably 18 seconds; when the high-temperature hot air temperature is 50°C, the R31 time can be selected as 8-15 seconds, preferably 9 seconds, and the R32 time can be selected as 10-18 seconds, preferably 13 seconds.

[0102] In other achievable ways, after the third processing stage, a fourth processing stage is further performed, in which the steam generating device 12 is turned off, the drying fan 13 is turned on, and the compressor is operated at the first frequency gear. The fourth processing stage is, for example, a cooling stage. The initial introduction rhythm corresponding to the fourth processing stage is R4, R4=R41 / R42; wherein: R41 is the time of ozone passing, R42 is the duration of stopping ozone passing, R21<R41<R31, R32<R42<R22, and / or, R2<R4<R3.

[0103] Specific, combined Figure 5, when it is detected that the steam generator 12 is turned off, the drying fan 13 is turned on, and the compressor is running at a low frequency, it is determined that it is the fourth processing stage (cooling process), and the initial ozone introduction rhythm is selected as R4 (process S541-S542), R4 is the ratio of the duration of ozone introduction and ozone stop, R4 = R41 / R42, R41 is the duration of ozone introduction, and R42 is the duration of ozone stop. Considering that the clothing processing state of the fourth processing stage is basically the same as that of the first processing stage, the same initial introduction rhythm as the first processing stage can be adopted, that is, R4 = R1.

[0104] The first treatment stage, the second treatment stage, the third treatment stage and the fourth treatment stage of this embodiment can be performed sequentially, or one or more of the first to fourth treatment stages can be selected to be performed according to the degree of ozone care for the clothes.

[0105] In a preferred embodiment, the rotation parameters of the laundry treatment drum include the rotation-stop ratio of the laundry treatment drum, and the target rotation rhythm is determined by optimizing the initial input rhythm according to the rotation parameters of the laundry treatment drum 2 in the laundry treatment stage, including: optimizing the initial input rhythm according to the rotation-stop ratio of the laundry treatment drum 2, and determining the optimized initial input rhythm as the target input rhythm. Wherein: when the ozone stop duration is the same, the greater the rotation-stop ratio of the laundry treatment drum 2, the shorter the ozone duration of the target input rhythm; and / or, the greater the rotation-stop ratio of the laundry treatment drum 2, the greater the target input rhythm.

[0106] Specific, combined Figure 5 , after determining the initial ozone introduction rhythm according to the clothing treatment stage, the rotation and stop ratio of the clothing treatment drum 2 is determined (processes S513, S523, S533 and S543). The rotation and stop ratio of the clothing treatment drum 2 can be roughly divided into three levels: more rotation and less stop, such as rotating for 55 seconds and stopping for 5 seconds, which is beneficial to ozone diffusion; medium rotation and medium stop, such as rotating for 20 seconds and stopping for 10 seconds, which is relatively beneficial to ozone diffusion; less rotation and more stop, such as rotating for 2 seconds and stopping for 58 seconds, which is not conducive to ozone diffusion.

[0107] In order to achieve a better care effect, except for special fabrics such as wool, which require a smaller turn-stop ratio, most fabrics are cared for with a rhythm of more turns and less stops. In a specific example, considering that the turn-stop ratio of the clothing treatment drum 2 is more turns than less stops, the turn-stop ratio of more turns and less stops is used as a reference standard. When the turn-stop ratio of the clothing treatment drum 2 is middle turn and middle stop, the ozone-passing time is increased by Δt1. When the turn-stop ratio of the clothing treatment drum 2 is less turns than more stops, the ozone-passing time is increased by Δt2, and Δt2 is greater than Δt1 (process S503-S505).

[0108] Taking the volume of the clothing treatment drum 2 as 85L and the ozone output of the ozone generating device as 2000mg / H as an example, the target ozone concentration in the clothing treatment drum 2 is 10ppm. In the second treatment stage, when the rotation and stop ratio of the clothing treatment drum 2 is 55s for rotation / 5s for stop, the optimized ozone introduction time R21' is 5 seconds, and the ozone stop time R22' is 18 seconds; if the rotation and stop ratio of the clothing treatment drum 2 is 20s for rotation / 10s for stop, the optimized ozone introduction time R211' can be selected as 6 seconds, and the ozone stop time R221' is 18 seconds; if the rotation and stop ratio of the clothing treatment drum 2 is 2s for rotation / 58s for stop, the optimized ozone introduction time R212' can be selected as 7 seconds, and the ozone stop time R222' is 18 seconds.

[0109] In other feasible embodiments, only the ozone stop time may be optimized according to the start-stop ratio of the clothing treatment drum 2, or both the ozone supply time and the ozone stop time may be optimized at the same time, so as to maintain the ozone concentration in the clothing treatment drum 2 within the target concentration range.

[0110] This embodiment optimizes the initial ozone introduction rhythm by combining the rotation and stop ratio of the clothing treatment drum 2 to obtain the target ozone introduction rhythm, thereby making the ozone introduction rhythm more reasonable and further maintaining the stability of ozone in the clothing treatment drum 2.

[0111] After determining the target ozone introduction rhythm, during the ozone clothing care process, the ozone introduction is controlled according to the determined introduction rhythm. The following is a detailed introduction to the ozone introduction process for different clothing treatment stages.

[0112] When the clothing treatment device runs the first treatment stage, ozone is first introduced into the clothing treatment drum 2. When the ozone concentration in the clothing treatment drum 2 reaches the target ozone concentration or when the ozone is introduced at a set flow rate for a target time, the step of controlling the clothing treatment device to control the ozone introduction at a target introduction rhythm is executed.

[0113] Specific, combined Figure 6, the first treatment stage is the initial stage of the ozone care process. In the first treatment stage, the ozone generator is turned on to make the ozone concentration in the barrel reach the target ozone concentration (process S63). The control of the target ozone concentration can be achieved by detecting the ozone concentration in the barrel by a detection instrument and then turning off the ozone generator. In the case of omitting the detection instrument, the ozone generator can be turned off after the time required for the target ozone concentration value is controlled. Then, the ozone is controlled according to the target ozone introduction rhythm R1' determined in step S32 to maintain the ozone concentration within the target concentration range (process S64). In one example, the target introduction rhythm R1' of the first treatment stage is the introduction rhythm determined by combining the initial ozone introduction rhythm R1 of the first treatment stage with the rotation and stop ratio of the clothing treatment barrel 2 (processes S61-S62). Taking the rotation and stop ratio of 55s / 5s as an example, the preferred ozone passage time R11' of R1' is 7 seconds, and the ozone stop time R12' is 15 seconds. Then it is determined whether the first treatment stage is finished (process S65). If the first treatment stage is finished, the next treatment stage is entered (process S66). If the first treatment stage is not finished, the ozone introduction is continued to be controlled according to the introduction rhythm R1'.

[0114] When the clothes processing device is running in the second processing stage, in the process of controlling the clothes processing device to control the ozone introduction at the target introduction rhythm, the operation states of the drying fan 13 and the steam generating device 12 are also controlled according to the odor removal demand;

[0115] When there is a need to remove odors, the drying fan 13 is controlled to change from an off state to an on state, and the steam generating device 12 is controlled to change from an on state to an off state, and the ozone ventilation time of the target input rhythm of the second treatment stage is extended, and the ozone ventilation stop time is shortened; after the odor removal is completed, the drying fan 13 is controlled to return to an off state from an on state, and the steam generating device 12 is controlled to return to an on state from an off state, and the ozone ventilation time and the ozone ventilation stop time of the target input rhythm of the second treatment stage are restored.

[0116] Specifically, after the first processing stage is completed, the second processing stage begins. Figure 7 In the second processing stage, the ozone is introduced according to the target ozone introduction rhythm R2' determined in step S32 (process S73) to maintain the ozone concentration in the drum. In one example, the target introduction rhythm R2' of the second processing stage is the introduction rhythm determined by combining the initial ozone introduction rhythm R2 of the first processing stage with the rotation and stop ratio of the laundry treatment drum 2 (processes S71-S72).

[0117] At the same time, in the second processing stage, the start-up state of the drying fan 13 is detected (process S75). If the drying fan 13 changes from the closed state to the started state, it indicates that there is a need for deodorization. Controlling the start-up of the drying fan 13 increases the ventilation condition in order to remove the odor in the drum and enhance the deodorization effect. In this process, the steam generating device 12 changes from the open state to the closed state, so it is necessary to increase the ozone flow time and reduce the ozone stop time to maintain the stability of the ozone concentration. Therefore, the ozone flow rhythm is adjusted to R2" (process S76). Taking the running rhythm of the clothing processing drum 2 as 55s / 5s, the preferred ozone flow time R21' of R2' is 5 seconds, and the ozone stop time R22' is 18 seconds; the adjusted ozone flow rhythm is R2", and the preferred ozone flow time R21" is 6 seconds, and the ozone stop time R22" is 17 seconds;

[0118] If the drying fan 13 is not started, the ozone injection is controlled at the target injection rhythm R2', and the state of the drying fan 13 and the start-up state of the steam generator 12 are detected. After the drying fan 13 is started and the ozone injection rhythm is adjusted to R2", it is continuously detected whether the drying fan 13 is turned off (process S77). If the drying fan 13 is turned off, it means that the deodorization is finished, and the ozone injection is switched back to the target injection rhythm R2'.

[0119] Then, it is detected whether the second processing stage is completed (process S74). If the second processing stage is completed, the next stage process is entered (process S78); if the second processing stage is not completed, the process returns to continue to detect the status of the drying fan 13, and the cycle is repeated.

[0120] When the clothes treatment device is running in the third treatment stage, in the process of controlling the clothes treatment device to control the ozone injection at the target injection rhythm, the temperature in the clothes treatment drum 2 is also obtained, and the target injection rhythm of the third treatment stage is adjusted according to the temperature in the clothes treatment drum 2. In the third treatment stage, this embodiment adjusts the ozone injection rhythm according to the temperature in the clothes treatment drum 2 to avoid the increase in temperature causing the ozone decay to accelerate, resulting in the ozone concentration in the drum constantly decreasing, affecting the sterilization or deodorization effects.

[0121] Preferably, the third processing stage includes n heating processes executed in sequence, different heating processes correspond to different temperature thresholds, and the target introduction rhythm of the third processing stage is adjusted according to the temperature in the clothing processing drum 2, including: when the clothing processing equipment enters the Nth heating process, controlling the clothing processing equipment to control the ozone introduction at the ozone introduction rhythm corresponding to the Nth heating process; when the temperature in the clothing processing drum 2 reaches the temperature threshold of the Nth heating process, extending the ozone introduction time of the Nth heating process and shortening the ozone stop time to serve as the ozone introduction rhythm of the N+1th heating process; wherein, the ozone introduction rhythm of the first heating process is the target introduction rhythm determined at least according to the current clothing processing stage of the clothing processing equipment, and 1≤N≤n, n and N are both integers.

[0122] Specific, combined Figure 8 In the third processing stage, the ozone is controlled by the target ozone rhythm R3' determined in step S31 (process S803). In one example, the target ozone rhythm R3' in the third stage is the initial ozone rhythm R3 in the third processing stage combined with the rotation ratio of the laundry treatment drum 2 to determine the ozone rhythm (process S801-S802).

[0123] Taking the high temperature hot air temperature of 50°C and the rotation and stop ratio of the laundry treatment drum 2 as 55s rotation / 5s stop, the preferred ozone passing time R31' of R3' is 9 seconds, and the ozone stopping time R32' is 13 seconds. Temperature has a great influence on the stability of ozone. As the temperature rises, its decomposition speed accelerates. When the temperature exceeds 100°C, the decomposition is very intense. When the temperature reaches a high temperature of 270°C, it can be immediately converted into oxygen.

[0124] Therefore, at the same time, the temperature K1 in the clothes processing drum 2 is detected (process S803), and it is determined whether the temperature K1 in the drum satisfies K1≥Ki1 (process S804). If K1≥Ki1, the ozone supply time is appropriately increased, and the ozone stop time is reduced to adjust the ozone supply rhythm to R31", so as to maintain the ozone concentration within the target value range (process S805). If K1<Ki1, no adjustment is required.

[0125] Adjust the ozone introduction rhythm to R31”. After running, continue to detect the temperature K2 in the barrel to determine whether the temperature K2 in the barrel satisfies K2≥Ki2 (process S806). If K2≥Ki2, appropriately increase the ozone introduction time and reduce the ozone stop time to adjust the ozone introduction rhythm to R32” (process S807); if K2<Ki2, no adjustment is required.

[0126] Adjust the ozone introduction rhythm to R32” After running, continue to detect the temperature K3 in the barrel to determine whether the temperature K3 in the barrel satisfies K3≥Ki3 (process S808). If K3≥Ki3, appropriately increase the ozone passage time and reduce the ozone stop time to adjust the ozone introduction rhythm to R33” (process S809); if K3<Ki3, no adjustment is required. During this period, detect the remaining time t1 of the entire ozone care process (process S809). If the remaining time t1≤ti (process S810), turn off the ozone generator and use high-temperature hot air to degrade the remaining ozone (process S811). The ozone generator can be turned off t2 time before the end of the drying process. The t2 time can be selected as 4-8 minutes.

[0127] Among them, Ki1 can be selected as 40-45℃, preferably 40℃; Ki2 can be selected as 50-55℃, preferably 50℃; Ki3 can be selected as 60-5℃, preferably 60℃; for example, when the temperature difference is detected to be greater than 10℃, that is, greater than 50℃, the adjusted ozone rhythm is R32", and the preferred ozone passage time R321" is 10 seconds, and the ozone stop time R322" is 12 seconds.

[0128] Finally, after the cooling process is completed, the entire ozone care process (process S812) can be ended.

[0129] Combination Fig. 9 , when the clothing treatment stage includes the fourth treatment stage (cooling stage), the fourth treatment stage is also performed between the second treatment stage and the third treatment stage. In the fourth treatment stage, the ozone introduction is controlled according to the target ozone introduction rhythm R4' determined in step S31 (process S93). In one example, the target introduction rhythm R4' of the fourth stage is the introduction rhythm determined by the initial ozone introduction rhythm R4 of the fourth treatment stage combined with the rotation ratio of the clothing treatment drum 2 (processes S91-S92). The target introduction rhythm R4' of the fourth treatment stage can be the same as the target introduction rhythm of the first stage, that is, R4'=R1', and then it is determined whether the fourth treatment stage is ended (process S94). If it is ended, the next stage is entered; otherwise, the fourth treatment stage is executed (process S95).

[0130] In general, in the ozone care method of this embodiment, a suitable ozone introduction rhythm is formulated according to the influence of different clothing treatment stages on ozone concentration, and the ozone introduction rhythm is adjusted in time according to the changes in the environment in the drum during the clothing treatment stage, to ensure that the ozone concentration is within the target concentration range, thereby ensuring the treatment effect of ozone on clothing.

[0131] In the ozone care method of the embodiment, by judging or obtaining the clothing treatment state in the clothing treatment stage, the ozone care process is generally divided into processes such as blowing low-temperature air, passing steam, cooling, blowing high-temperature hot air to dry, and finally blowing cooling, and the action conditions such as blowing, spraying steam, and blowing high-temperature hot air have different effects on the diffusion and decay of ozone in the clothing treatment drum 2. Specifically, according to the speed of promoting ozone diffusion and concentration increase from fast to slow: spraying steam is the fastest, blowing is the second, and blowing high-temperature hot air is the third. According to the speed of promoting ozone decomposition from fast to slow, it is: blowing high-temperature hot air is the fastest, blowing is the second, and steam spraying is relatively slow. According to this rule, the rhythm of ozone introduction can be formulated as follows: the duration of ozone passing in the blowing stage is moderate, and the duration of ozone closing is moderate; the duration of ozone passing in the steam spraying stage is shorter, and the duration of ozone closing is longer; the duration of ozone passing in the high-temperature hot air blowing stage is longer, and the duration of ozone closing is shorter. In this way, we can directly use its rules to formulate an appropriate rhythm for ozone introduction, which is simple and effective, and avoids problems such as frequent detection, judgment and slow response of components, as well as time differences caused by detection errors, which cause large fluctuations in ozone concentration (the detector has detection delays, with a response time of 1.5s or more, and the detection instrument does not directly detect the ozone concentration in the cylinder). It effectively maintains the stability of ozone concentration and ensures the effects of sterilization and deodorization.

[0132] The ozone care method of the present embodiment also optimizes the rhythm of ozone introduction in combination with the rotation and stop ratio of the clothing treatment drum 2 in each process. For example, when the rotation time is long, it is beneficial to ozone diffusion, and the ozone passage time is appropriately reduced; when the rotation time is short, it is not conducive to ozone diffusion, and the ozone passage time is appropriately increased to make the ozone introduction rhythm more reasonable. In addition, the present embodiment does not require the addition of detection instruments (detection instruments are relatively expensive and difficult to install, with detection delays and detection accuracy affected by ambient temperature and humidity), which not only reduces costs but also avoids detection deviations caused by the delay of the detector, detection position, environmental conditions, etc.

[0133] In the third treatment stage (hot air blowing stage) of the ozone care method of this embodiment, the third treatment stage can be divided into multiple heating processes, such as a heating process of 5°C-10°C. For each heating process of the temperature, the degradation of ozone will be relatively accelerated. Accordingly, the duration of ozone passing is appropriately extended, and the duration of ozone closing is appropriately shortened. In the second treatment stage (steam passing stage), the fan will be started for a certain period of time in the middle process to blow away the odor. According to the change of this condition, it can be equivalent to the process of blowing high-temperature humid air to control the introduction of ozone. The duration of ozone passing is appropriately extended, and the duration of ozone closing is appropriately shortened. In this way, through fine repair of details, the flexibility of ozone concentration control is increased, the purpose of preventing large deviations (mutations) in ozone concentration is achieved, the stability of ozone concentration in the clothing treatment drum 2 is ensured, and the treatment effect of ozone on clothing is ensured.
