Background
With the increasing level of living of people, washing machines are used more and more frequently in daily life of people. When a user needs to wash clothes, the clothes can be cleaned by only putting the clothes to be washed and the detergent into a washing cylinder of the washing machine and then running the washing machine. However, only the stain on the laundry is removed only by the washing operation, and bacteria, viruses, and the like on the laundry cannot be removed.
For this reason, the clothes are generally sterilized by ultraviolet irradiation, ozone, silver ions, and the like. However, the ultraviolet irradiation sterilization method generally has a sterilization effect only on the surface of the clothes irradiated with ultraviolet rays, and the space in the washing drum is limited, so that it is difficult to realize ultraviolet ray coverage on all the surface of the clothes. The ozone sterilization mode has good sterilization effect, but ozone is harmful to human bodies, the national indoor air quality standard has strict limitation on the content of ozone, and the ozone has strong oxidizing property, is easy to fade clothes, and is difficult to popularize in a large area. The silver ion sterilization mode is to add nano material on the surface of the inner and outer cylinders of the washing machine, and release silver ions capable of sterilizing during washing, so as to achieve the sterilization effect. However, the silver ion sterilization method requires that the clothes and silver ions are fully contacted to achieve the aim of sterilization, and the aim of sterilization cannot be achieved in places where the clothes and silver ions are not contacted.
Accordingly, there is a need in the art for a new solution to the above-mentioned problems.

As the ionic substances can effectively remove bacteria, viruses and the like, bacteria, viruses and the like in the inner cylinder and on the clothes to be treated in the inner cylinder can be killed by the ionic substances in the gas. That is, the application can effectively remove bacteria, viruses and the like on the inner cylinder and the clothes to be treated positioned in the inner cylinder through the optical plasma fresh air device, and obtain better sterilization effect. Meanwhile, the air introduced into the inner cylinder by the fan can promote the original air in the inner cylinder to be discharged, so that the air flow in the inner cylinder can be enhanced, the purposes of deodorizing and preventing mold and bacteria from breeding are achieved, and the user experience is effectively improved.
The control method of the invention comprises the following steps: and acquiring a washing mode of the clothes treatment equipment, acquiring a current operation stage of the washing mode if the washing mode is a mixed washing mode, controlling the inner cylinder to rotate at a preset inner cylinder rotating speed if the current operation stage is in a pre-water inlet stage, and controlling the light plasma tube and the fan to operate while, before or after controlling the inner cylinder to rotate at the preset rotating speed. Through the control mode, when the washing mode is the mixed washing mode and the current operation stage is in the pre-water inlet stage, the inner cylinder is controlled to rotate at the preset inner cylinder rotating speed, and the operation of the light plasma tube and the fan is controlled, so that the operation of the light plasma tube and the fan is combined with the operation stage of the mixed washing mode, the smooth operation of the mixed washing mode is ensured, the washing effect is ensured, and meanwhile, the outer cylinder, the inner cylinder and clothes positioned in the inner cylinder are better subjected to disinfection treatment, and a better sterilization effect is obtained.
Further, the light plasma tube and the fan each have a high-grade, a medium-grade, and a low-grade, and the step of "controlling the operation of the light plasma tube and the fan" further includes: the control light plasma tube and the fan both operate in mid range. Therefore, more ionic substances can be generated by ionizing air through the light plasma tube, more air is introduced into the light plasma fresh air device through the fan, and the gas containing more ionic substances is sent into the inner cylinder to sterilize the outer cylinder, the inner cylinder and clothes in the inner cylinder, so that a better sterilization effect is obtained.
Further, the light plasma fresh air device is arranged below the outer cylinder, a waterproof ventilation valve is arranged between the light plasma fresh air device and the outer cylinder, and the light plasma fresh air device can be communicated with or not communicated with the outer cylinder through the waterproof ventilation valve. Under the condition, when, before or after the inner cylinder is controlled to rotate at the preset inner cylinder rotating speed, the waterproof ventilation valve is controlled to be opened, and as the outer cylinder is communicated with the inner cylinder, the optical plasma fresh air device can be communicated with the inner cylinder, and then the gas containing ionic substances enters the inner cylinder through the rotation of the inner cylinder and the operation of the optical plasma tube and the fan, the outer cylinder, the inner cylinder and clothes positioned in the inner cylinder are subjected to sterilization treatment, and a good sterilization effect is obtained.
The laundry treating apparatus further comprises a water inlet valve arranged to be capable of delivering water into the drum when opened. After the light plasma tube and the fan are controlled to run for a first preset period of time, the light plasma tube and the fan are operated for a period of time, more gas containing ionic substances is fed into the inner cylinder, bacteria, viruses and the like on the outer cylinder, the inner cylinder and clothes are basically killed, at the moment, the water inlet valve is controlled to be opened, water is fed into the inner cylinder, and the clothes management equipment is controlled to run in a mixed washing mode, so that clothes are washed. Before the water inlet valve is controlled to be opened, the waterproof air-permeable valve is controlled to be closed, and the photoplasma pipe and the fan are controlled to stop running, so that the photoplasma fresh air device is prevented from being damaged due to the fact that water fed into the inner barrel through the water inlet valve enters the photoplasma fresh air device. Through such control mode, can obtain better washing effect when guaranteeing degerming effect to can also effectively avoid damaging light plasma new trend device, promote user experience.
If the current operation stage is in the spin-drying stage, the waterproof and air-permeable valve is controlled to be opened, and the light plasma tube and the fan are controlled to operate in high grade at the same time or after the waterproof and air-permeable valve is controlled to be opened. That is, when the operation stage is the spinning stage, the waterproof and ventilation valve is opened, and both the light plasma tube and the fan are controlled to operate in a high-grade. Therefore, more gas containing ionic substances can be sent into the inner cylinder through the light plasma tube and the fan, and the outer cylinder, the inner cylinder and clothes in the inner cylinder can be better sterilized, so that a better sterilizing effect is obtained.
Before the waterproof ventilation valve is controlled to be opened, the operation time length of the spin-drying stage is obtained, and the operation time length is compared with a time length threshold value. If the running time length is greater than the time length threshold, at the moment, basically no washing water exists in the outer cylinder, at the moment, the waterproof ventilation valve is controlled to be opened, and no washing water enters the shell after the waterproof ventilation valve is opened, so that the stable running of the optical plasma fresh air device can be ensured, and a better degerming effect is obtained. If the operation time length is less than or equal to the time length threshold value, at the moment, a small amount of washing water can still exist in the outer cylinder, at the moment, the waterproof ventilation valve is not controlled to be opened, and the damage of the photoplasm fresh air device caused by the entering of the washing water into the shell is avoided. By the control mode, a good sterilization effect can be obtained on the premise of avoiding damaging the light plasma fresh air device.
After the light plasma tube and the fan are controlled to run in a high-grade mode for a second preset time period, the light plasma tube and the fan run for a long time, more gas containing ionic substances is fed into the inner cylinder, bacteria, viruses and the like on the outer cylinder, the inner cylinder and clothes are basically killed, and at the moment, the light plasma tube and the fan are controlled to stop running, so that a good sterilization effect can be obtained, and electric energy can be saved.
Further, the photoplasma fresh air device is arranged above the outer cylinder, and the clothes treatment equipment further comprises a water inlet valve which can send water into the inner cylinder when being opened. In this case, after the light plasma tube and the fan are controlled to operate for a third preset period of time, the light plasma tube and the fan are operated for a period of time, more gas containing ionic substances is sent into the inner cylinder, bacteria, viruses and the like on the outer cylinder, the inner cylinder and clothes are basically killed, at the moment, the water inlet valve is controlled to be opened, water is sent into the inner cylinder, and the clothes management device is controlled to operate in a mixed washing mode, so that clothes are washed. And simultaneously or after the water inlet valve is controlled to be opened, controlling the light plasma tube and the fan to operate at a low gear until the mixed washing mode operation is finished. As the sterilization treatment is carried out in the stage before water inflow, the contents of bacteria, viruses and the like remained on the outer cylinder, the inner cylinder and clothes are lower, so that the light plasma tube and the fan are operated in lower operation gear when or after the water inlet valve is opened until the operation of the mixed washing mode is finished, thereby meeting the sterilization requirement and reducing the electric energy consumption. By such a control method, the electric power consumption can be reduced while ensuring the sterilization effect.
If the current operation stage is in a non-water inlet front stage, as the optical plasma fresh air device is arranged above the outer cylinder, no washing water enters the optical plasma fresh air device even if the optical plasma fresh air device is started, at the moment, the optical plasma tube and the fan are controlled to operate in a middle grade, and gas containing ionic substances is introduced into the inner cylinder to kill the outer cylinder, the inner cylinder and clothes in the inner cylinder, so that a better sterilization effect is obtained.
Further, before the current operation stage of the washing mode is obtained, the odor concentration in the inner cylinder is obtained, the odor concentration is compared with the concentration threshold value, if the odor concentration is larger than the concentration threshold value, the odor concentration is higher than the concentration threshold value, which indicates that the inner cylinder has peculiar smell and more bacteria, viruses and the like possibly exist in the inner cylinder, at the moment, the current operation stage of the washing mode is obtained, and after the current operation stage is obtained, the operation of the inner cylinder, the light plasma tube and the fan is controlled according to the specific conditions of different operation stages. If the odor concentration is smaller than or equal to the concentration threshold value, the odor is not present in the inner barrel, and the disinfection treatment is not needed, and at the moment, the present operation stage of the washing mode is not acquired. By such a control method, the electric energy consumption is reduced while the sterilization effect is ensured.

In order to remove bacteria, viruses, etc. from laundry, drum washing machines generally perform sterilization treatment on laundry by means of ultraviolet irradiation, ozone, silver ions, etc. However, the ultraviolet radiation sterilization system is generally capable of only sterilizing clothes irradiated with ultraviolet radiation, and has a limited sterilization effect. The sterilization effect of the ozone sterilization mode is good, but ozone is harmful to human bodies. The silver ion degerming mode needs to be contacted with clothes to achieve the aim of degerming, and degerming effect is limited. Therefore, the invention provides a control method of clothes treatment equipment, which can combine the operation of the light plasma tube and the fan with the operation stage of the mixed washing mode, ensure the smooth operation of the mixed washing mode and obtain better degerming effect by controlling the inner cylinder to rotate at the preset inner cylinder rotating speed and controlling the light plasma tube and the fan to operate when the washing mode is the mixed washing mode and the current operation stage is in the pre-water inlet stage.
First, possible implementations of the laundry management apparatus of the present invention are explained with reference to fig. 1 to 4.

The laundry is put into the inner cylinder 2, and the drum washing machine is started to clean the laundry. The drum washing machine may not include the outer tub 3.
The optical plasma fresh air device 4 comprises a shell 41, an optical plasma tube 42 and a fan 43, wherein the optical plasma tube 42 is a U-shaped tube, and the fan 43 is an axial flow fan. The light plasma tube 42 and the fan 43 are arranged in the shell 41, and the light plasma tube 42 and the fan 43 can be isolated from the external environment through the shell 41, so that dust in the environment can be prevented from being deposited on the light plasma tube 42 and the fan 43 to influence the efficiency of ionizing air, and the light plasma tube 42 and the fan 43 are wetted by water vapor and even short-circuited, thereby ensuring the stable operation of the light plasma fresh air device 4. The housing 41 is generally rectangular in cross section and has an air inlet 411 and an air outlet 412, the air inlet 411 being in communication with the environment. The air outlet 412 is provided with an air outlet pipeline 4121, one end of the air outlet pipeline 4121 is connected with the air outlet 412, and the other end of the air outlet pipeline 4121 is connected with the outer barrel 3, so that the air outlet 412 and the outer barrel 3 are communicated with each other. The inner cylinder 2 is provided with a plurality of water through holes, that is, the outer cylinder 3 is communicated with the inner cylinder 2, so that the air outlet 412 can be communicated with the inner cylinder 2. An air duct is formed between the air inlet 411 and the air outlet 412, at least a part of the light plasma tube 42 is located in the air duct, the light plasma tube 42 is arranged to ionize air when energized to generate a gas containing ionic substances, the fan 43 is arranged to introduce air in the environment into the housing 41 via the air inlet 411 and to send the gas ionized via the light plasma tube 42 out via the air outlet 412.
By such arrangement, under the action of the fan 43, air in the environment enters the casing 41 through the air inlet 411, and the light plasma tube 42 positioned in the casing 41 can generate hydroxyl radicals, free oxygen atoms and superoxide ion plasma substances by the pure oxygen and water in the air when being electrified, and the gas containing the ion substances enters the inner cylinder 2 through the air outlet 412, so that the ion substances can decompose harmful substances such as volatilizable organic substances into carbon dioxide and water, and can destroy bacterial cell membranes to achieve the aim of bacteriostasis. In this way, bacteria, viruses and the like on the outer cylinder 3, the inner cylinder 2 and the clothes to be washed positioned in the outer cylinder can be killed by ionic substances in the gas, that is, the bacteria, viruses and the like on the outer cylinder 3, the inner cylinder 2 and the clothes to be washed positioned in the inner cylinder can be effectively removed by the optical plasma fresh air device 4, and a good sterilization effect is obtained. Meanwhile, the air introduced into the inner cylinder 2 by the fan can promote the original air in the inner cylinder 2 to be discharged, so that the air flow in the inner cylinder can be enhanced, the purposes of deodorizing and preventing mold and bacteria from breeding are achieved, and the user experience is effectively improved. Obviously, the cross section of the housing 41 may also be provided in other possible shapes, such as oval, square, hexagonal, etc.
It should be noted that, the light plasma tube 42 may be configured in other possible forms such as a strip tube, a W-shaped tube, etc., and those skilled in the art may flexibly select a specific configuration of the light plasma tube 42 according to a specific application scenario without departing from the principles of the present application, so long as the light plasma tube 42 can ionize air to generate a gas containing ionic substances when energized.
It should be noted that, the fan 43 may be any other possible type, such as a cross-flow fan, a centrifugal fan, etc., and those skilled in the art may flexibly select a specific type of the fan 43 according to a specific application scenario without departing from the principles of the present application, so long as the fan 43 can introduce air in the environment into the housing 41 through the air inlet 411 and send the air ionized by the light plasma tube 42 out through the air outlet 412.
The air inlet 411 may be directly connected to the space between the outer tub 3 and the housing 1, and when the optical plasma fresh air device 4 is operated, air in the space between the outer tub 3 and the housing 1 enters the housing 41 through the air inlet 411, is ionized by the optical plasma tube 42, and then enters the inner tub 2. Of course, an air intake duct may be provided at the air intake 411, in which case a vent hole is provided in the housing 1, and the end of the air intake duct remote from the housing 41 communicates with the vent hole in the housing 1, so that communication between the air intake 411 and the environment can be achieved. Obviously, when the circulation duct is provided in the drum washing machine, the end of the air intake duct away from the housing 41 may also be communicated with the circulation duct. A person skilled in the art may flexibly select a specific arrangement of the air inlet 411 in communication with the environment without departing from the principles of the present application, as long as air in the environment can enter the housing 41 via the air inlet 411.
In one possible embodiment, the light plasma tube 42 of the present application can emit ultraviolet light with a wavelength of 170-190nm when energized, and ionize air to generate more ionic substances under the effect of the ultraviolet light with the wavelength, so that the gas containing ionic substances obtained after ionization by the light plasma tube 42 can remove more bacteria, viruses, etc., and thus a better sterilization effect can be obtained.
Obviously, the light plasma tube 42 can emit ultraviolet light of other wavelengths when energized. When the light plasma tube 42 emits ultraviolet light of other wavelengths, the ionized air generates less ionic substances than ultraviolet light of 170-190nm, but a certain sterilization effect can be obtained.
As shown in fig. 1, the air inlet 411 and the air outlet 412 are provided at opposite sides of the housing 41 (i.e., left and right sides of the housing 41 shown in fig. 1), respectively, such that air in the environment enters the housing 41 through the air inlet 411 on the right side and is then discharged from the air outlet 412 on the left side by the fan 43. A mount 44 is provided in the housing 41 at a position near the air inlet 411, and the optical plasma tube 42 and the fan 43 are provided on both sides of the mount 44 in the air flow direction (i.e., the left-right direction in fig. 1), respectively. When assembled, the light plasma tube 42 extends in the air flow direction (i.e., extends in the left-right direction in fig. 1), and the fan 43 is aligned with the air inlet 411, so that the fan 43 is disposed at the upstream side of the light plasma tube 42 in the air flow direction and in the vicinity of the air inlet 411. Under the action of the fan 43, air in the environment enters the casing 41 through the air inlet 411 and is blown to the light plasma tube 42 by the fan 43, so that the air can be in contact with the light plasma tube 42 in the whole flow path in the casing 41, and the air can be in more sufficient contact with the light plasma tube 42, so that more ionic substances can be ionized to obtain better sterilization effect.
It should be noted that the air inlet 411 and the air outlet 412 may be disposed on the housing 41 in other distribution manners. As shown in fig. 2 in particular, according to the orientation shown in fig. 2, the air inlet 411 is provided on the right side of the housing 41, and the air outlet 412 is provided on the upper side of the housing 41, i.e., the air inlet 411 and the air outlet 412 are provided on the adjacent sides of the housing 41, respectively. Air outlet 412 is located near the end of light plasma tube 42 remote from mount 44. In this way, after the air in the environment enters the housing 41 through the air inlet 411 on the right side, the air is blown to the optical plasma tube 42 by the fan 43, contacts with the optical plasma tube 42 and is ionized, and then is discharged through the air outlet 412 on the upper side, so that a substantially L-shaped air channel is formed in the housing 41, and the air outlet 412 is arranged near the left side of the housing 41, so that the air containing the ionic substances in the housing 41 can be timely discharged. Of course, it is also possible that the air inlet 411 is provided on the right side of the housing 41, the air outlet is provided on the lower side of the housing 41, and the like. A person skilled in the art may flexibly select a specific arrangement position of the air inlet 411 and the air outlet 412 on the housing 41 according to a specific application scenario without departing from the principles of the present application, as long as air in the environment can enter the housing 41 through the air inlet 411 and ionized air can be discharged through the air outlet 412.
As shown in fig. 1 and 3, the photoplasma fresh air device 4 further includes a waterproof and breathable member, which is a waterproof and breathable membrane 45, the waterproof and breathable membrane 45 being configured to allow only gas to pass through. In the present application, the waterproof and breathable film 45 may be disposed at the air outlet 412 by means of adhesion, screwing, clamping, or the like. The waterproof and breathable film 45 is a novel high-molecular waterproof material and mainly comprises three layers: PP spunbond nonwoven fabric, PE polymer breathable film, PP spunbond nonwoven fabric. The waterproof and breathable film 45 achieves the aim of preventing water from passing through by the following principle: in the state of water vapor, the water particles are very tiny, and can smoothly permeate the capillary tube to the other side according to the principle of capillary motion, so that the vapor permeation phenomenon occurs. After the water vapor is condensed into water drops, the particles become larger, and the water molecules cannot be smoothly separated from the water drops to permeate to the other side due to the action of the surface tension of the water drops (mutual 'pulling and counterbalance' among the water molecules), namely, the water permeation is prevented, so that the vapor permeable membrane has a waterproof function.
When the light plasma fresh air device 4 is operated, air in the environment enters the shell 41 through the air inlet 411 and is ionized by the light plasma tube 42, then passes through the waterproof breathable film 45 and enters the inner cylinder 2 through the air outlet pipeline 4121. Thus, even if the drum washing machine is in the washing process, more washing water splashes, and the washing water in the outer drum 3 cannot enter the shell 41 through the air outlet 412 under the blocking effect of the waterproof and breathable film 45, so that the stable operation of the optical plasma fresh air device 4 can be ensured.
The waterproof and breathable member may be a valve 46, for example, the valve 46 may be a solenoid valve. As shown in fig. 2 and 4, a valve 46 is disposed on the air outlet pipe 4121, and the valve 46 is opened when the optical plasma fresh air device 4 is in operation, and the valve 46 is closed when the optical plasma fresh air device 4 is not in operation, so that the washing water can be blocked from entering the housing 41, and the stable operation of the optical plasma fresh air device 4 is ensured. Of course, when the waterproof and breathable member is the valve 46, the air outlet 412 may be provided without the air outlet pipe 4121, and the valve 46 may be directly clamped at the air outlet 412, in which case the valve 46 may be a threaded waterproof and breathable valve, a snap-in waterproof and breathable valve, a twist-clip waterproof and breathable valve, a plug waterproof and breathable valve, or other possible types. The person skilled in the art can flexibly select the specific arrangement form of the waterproof and breathable member according to the specific application scenario, as long as it allows only gas to pass through, without departing from the principle of the present application.
It will be appreciated that the photoplasma fresh air device 4 may not include a waterproof ventilation member, in which case, in order to avoid the influence of the wash water on the photoplasma fresh air device 4, the photoplasma fresh air device 4 may be disposed on the top side of the outer sidewall of the outer tub 3, or at a position close to the top side or other position higher than the level of the wash water.
As shown in fig. 1 and 2, the photoplasma fresh air device 4 further comprises a control module 47, and the control module 47 can selectively control the operation of the photoplasma tube 42 and the fan 43 according to the odor concentration in the inner cylinder 2, and can also control the operation of the water inlet valve, the photoplasma tube 42 and the fan 43.
The light plasma fresh air device 4 may not be provided with a control module alone, but may be a control chip of the drum washing machine itself, or a functional module or a functional unit of a general controller.
In this case, when the waterproof and breathable member is the valve 46, the valve 46 is connected to the control module 47, and the control module 47 is provided so as to be able to control the opening and closing of the valve 46.
A possible implementation of the optical plasma fresh air device 4 according to the present application provided on the drum washing machine will be described with reference to fig. 3 and 4.
As shown in fig. 3 and 4, a through hole (not shown) is provided on the upper side of the outer tub 3, and one end of the air outlet pipe 4121 is connected to the air outlet 412 of the optical plasma fresh air device 4, and the other end is connected to the through hole, so that the optical plasma fresh air device 4 is disposed above the outer tub 3. When the drum washing machine is operated, the optical plasma fresh air device 4 is started, and the gas containing ionic substances generated by the optical plasma fresh air device 4 enters the outer drum 3 through the gas outlet 412 and then enters the inner drum 2, so that the drum washing machine and the laundry in the inner drum 2 are subjected to sterilization treatment, and the original air in the inner drum 2 is promoted to be discharged, so that good sterilization and deodorization effects can be obtained.
In this case, in order to prevent the washing water in the outer tub 3 from entering the housing 41, the waterproof and breathable member is provided with a valve 46, and when the drum washing machine is operated and the water is present in the outer tub 3, the valve 46 is closed, and when the drum washing machine is not operated or the water is not present in the outer tub 3, the valve 46 may be opened, and the drum washing machine is sterilized and deodorized by the optical plasma fresh air device 4. Of course, the optical plasma fresh air device 4 may also be disposed at a position near the lower side or lower side of the outer tub 3, and those skilled in the art may flexibly select a specific setting position of the optical plasma fresh air device 4 in the casing 1 according to a specific application scenario without departing from the principles of the present application, so long as the drum washing machine can be sterilized.
The drum washing machine includes a control panel (not shown) provided with an indicator lamp configured to display an operation state of the light plasma fresh air device 4. Specifically, for example, the indication lamp indicates that the optical plasma fresh air device 4 is in a normal operation state when the indication lamp indicates yellow, the indication lamp indicates that the optical plasma fresh air device 4 is in an operation completion state when the indication lamp indicates green, and the indication lamp indicates that the optical plasma fresh air device 4 is in an abnormal operation state when the indication lamp indicates red.
It should be noted that, the working states of the light plasma fresh air device 4 displayed by the indicator lamps with different colors are only described as an example, and obviously, the working states can also represent other working states, for example, the light plasma fresh air device 4 is in a normal operation state when the indicator lamp displays red, the light plasma fresh air device 4 is in an operation completion state when the indicator lamp displays green, and the light plasma fresh air device 4 is in an abnormal operation state when the indicator lamp displays yellow. Without deviating from the principle of the application, a person skilled in the art can flexibly select a specific implementation mode of the indicator light to display the working state of the optical plasma fresh air device 4 according to a specific application scene, so long as the working state of the optical plasma fresh air device 4 can be displayed through the indicator light.
In the present application, the drum washing machine is provided with a scent detection module provided in the inner tub, which is configured to be able to detect scent concentration in the cabinet. For example, the odor detection module may be an odor sensor, and the odor sensor is an odor identifier based on MEMS (english full name: microelectro Mechanical Systems) principle, which has advantages of high identification accuracy and high speed.
Obviously, the smell detection module can also be an olfactory cell chip, and the olfactory cell chip comprises a cell membrane, a gas sensor array, a processor and a signal transmitter, wherein the cell membrane is covered on the gas sensor array and is used for filtering smell molecules. The gas sensor array is used for detecting the filtered odor molecules and generating an electrical signal. The processor is connected with the gas sensor array and is used for processing the electric signals generated by the gas sensor array. The signal transmitter is connected with the processor and used for transmitting the electric signals processed by the processor. The specific setting form of the odor detection module can be flexibly selected by a person skilled in the art according to specific application scenes, so long as the odor concentration in the inner barrel can be detected through the odor detection module.
In the application, the light plasma tube and the fan are provided with a high grade, a medium grade and a low grade, that is, the light plasma tube can respectively run at a high grade frequency, a medium grade frequency and a low grade frequency, the frequency of the light plasma tube is related to the number of ionic substances generated by ionization of the light plasma tube, and the larger the frequency of the light plasma tube is, the more the number of ionic substances generated by ionization of the light plasma tube is. The fan can respectively run at a high-gear rotating speed, a medium-gear rotating speed and a low-gear rotating speed, and the larger the rotating speed of the fan is, the larger the air quantity is. Obviously, the light plasma tube and the fan can also have more or less gears such as four or five, or two, one, etc., and can be flexibly selected by a person skilled in the art according to specific application scenes.
In the present application, the drum washing machine further comprises a water inlet valve configured to be capable of supplying water into the inner tub when the water inlet valve is opened. When the drum washing machine is used for washing clothes, the water inlet valve is opened to feed washing water into the inner drum, and when the water is not required to be fed into the inner drum, the water inlet valve is closed.
In the present application, the mixed washing mode generally includes a pre-water inlet stage, a washing stage, a rinsing stage and a spin-drying stage, and washing water is generally stored in the tub during the washing stage and the rinsing stage. When the optical plasma fresh air device is positioned below the outer cylinder, the optical plasma fresh air device is operated at the stage that washing water exists in the outer cylinder, so that the washing water possibly enters the optical plasma fresh air device, and the optical plasma fresh air device is damaged.
Possible implementations of the control method of the drum washing machine of the present application are described below with reference to fig. 5 to 9.
As shown in fig. 5, in one possible embodiment, the control method of the present application includes:
s100: acquiring a washing mode of the drum washing machine;
s101: when the washing mode is a mixed washing mode, acquiring the current operation stage of the washing mode;
s102: if the current operation stage is in the pre-water inlet stage, the inner cylinder is controlled to rotate at a preset inner cylinder rotating speed;
S103: controlling the operation of the light plasma tube and the fan.
In S100, a washing mode of the drum washing machine is acquired.
The washing mode of the drum washing machine may be preset by a user through a remote controller, a control panel on the drum washing machine, an APP communicating with the drum washing machine, or may be automatically determined by the drum washing machine according to factors such as the type of laundry, the number of laundry, the current season, and the like.
In S101, based on the washing mode of the drum washing machine obtained in S100, if the washing mode is a hybrid washing mode, a current operation stage of the hybrid washing mode is obtained.
In S102, based on the current operation stage acquired in S101, if the current operation stage is in the pre-water inlet stage, it is indicated that the laundry is ready to be washed at this time, but water inlet washing has not yet been started, and the drum washing machine has not yet started to operate the hybrid washing mode, at this time, the drum is controlled to rotate at a preset drum rotation speed, and the laundry is disturbed by the drum rotation.
It should be noted that, a person skilled in the art may flexibly determine the preset inner cylinder rotation speed according to a specific application scenario, which is not limited in the present application.
In S103, after the inner cylinder is controlled to rotate at a preset inner cylinder rotation speed, that is, after S102 is executed, the operation of the light plasma tube and the fan is controlled, air is ionized by the light plasma tube to generate air containing ionic substances, the air in the environment is introduced into the light plasma fresh air device through the fan, the air containing the ionic substances is sent into the inner cylinder, and the outer cylinder, the inner cylinder and clothes in the inner cylinder are subjected to disinfection treatment. In addition, as the rotation of the inner cylinder disturbs the clothes, the clothes can be fully contacted with the gas containing ionic substances, so that the clothes can be better disinfected and better degerming effect is obtained.
By the control mode, the operation of the light plasma tube and the fan is combined with the operation stage of the mixed washing mode, so that the smooth operation of the mixed washing mode is ensured, the washing effect is ensured, and meanwhile, the better sterilization effect is obtained.
It should be noted that, the operation of the light plasma tube and the fan may be controlled while or before the inner tube is controlled to rotate at the preset inner tube rotation speed, that is, S103 may be performed while or before S102 is performed. On the premise of not deviating from the principle of the application, a person skilled in the art can flexibly select and control the specific time for the operation of the light plasma tube and the fan according to specific application scenes, so long as a better degerming effect can be obtained when the current operation stage is a pre-water inlet stage.
In one possible implementation manner, the controlling the operation of the optical plasma tube and the fan in step S103 specifically includes: both the light plasma tube and the fan are controlled to operate at a mid-range, i.e., the light plasma tube is controlled to operate at a mid-range frequency, the fan is controlled to operate at a mid-range rotational speed, e.g., the light plasma tube is controlled to operate at a frequency of 5w, and the fan is controlled to operate at a rotational speed of 650 r/min. Through such control mode, the light plasma tube can ionize the air and produce more ionic state substances, and the fan can introduce more air in the environment into the casing to send more gas containing ionic state substances into the inner tube, just so can obtain better degerming effect in the stage before intaking. It is obvious that, in step S103, both the light plasma tube and the fan may be controlled to operate in a high-grade or a low-grade, however, if both the light plasma tube and the fan are controlled to operate in a high-grade, a better sterilization effect is obtained, but the electric energy consumed in the operation process of the light plasma fresh air device is increased. If both the plasma tube and the fan are controlled to operate in a low gear, the sterilization effect that can be obtained accordingly is reduced.
In one possible embodiment, the optical plasma fresh air device is arranged below the outer cylinder, and a waterproof ventilation valve is arranged between the optical plasma fresh air device and the outer cylinder, and the optical plasma fresh air device can be communicated with or not communicated with the outer cylinder through the waterproof ventilation valve.
A possible implementation of the control method of the present invention when the optical plasma fresh air device is disposed below the outer tub and a waterproof ventilation valve is provided between the optical plasma fresh air device and the outer tub will be described below with reference to fig. 6 and 7.
As shown in fig. 6, in one possible embodiment, the control method of the present invention further includes:
s200: acquiring a washing mode of the drum washing machine;
s201: if the washing mode is a mixed washing mode, acquiring the current running stage of the washing mode;
s202: judging whether the current operation stage is in a pre-water inlet stage or not, if so, executing S203; if not, executing S204;
s203: controlling the opening of the waterproof ventilation valve;
s204: judging whether the current operation stage is in a spin-drying stage, if so, executing S206; if not, executing S205;
s205: the opening of the waterproof air-permeable valve is not controlled, and the operation of the light plasma tube and the fan is not controlled;
s206: controlling the opening of the waterproof ventilation valve;
s207: controlling the operation of the light plasma tube and the fan.
In S200, similar to S100, a washing mode of the drum washing machine is acquired.
In S201, similarly to S101, based on the washing mode of the drum washing machine acquired in S200, if the washing mode is a hybrid washing mode, a current operation stage of the hybrid washing mode is acquired.
In S202, based on the current operation stage obtained in S201, it is determined whether the current operation stage is in a stage before water inflow, if no wash water exists in the outer cylinder of the operation stage before water inflow, at this time, the waterproof and breathable valve is controlled to be opened, that is, S203 is executed, so that the optical plasma fresh air device is communicated with the inner cylinder.
After the waterproof and breathable valve is opened, S102 is performed, that is, the inner cylinder is controlled to rotate at a preset inner cylinder rotation speed. And then controlling the operation of the light plasma tube and the fan to kill the outer cylinder, the inner cylinder and clothes in the inner cylinder.
It should be noted that, the specific implementation manner of S102 and the control steps after S102 are implemented have been described in detail above, that is, the specific steps of controlling the inner barrel, the light plasma tube and the fan in the case that the current operation stage is in the pre-water stage have been described in detail above, which will not be described herein.
In one possible embodiment, when the current operation stage is in the pre-water inlet stage, after the operation of the light plasma tube and the fan is controlled for a first preset period of time, for example, after the operation of the light plasma tube and the fan is controlled for 15min, the light plasma tube and the fan are operated for a period of time, more gas containing ionic substances is sent into the inner cylinder, most of bacteria, viruses and the like on the outer cylinder, the inner cylinder and clothes are killed, at this time, the water inlet valve is controlled to be opened, water is sent into the inner cylinder, and the clothes management device is controlled to operate in a mixed washing mode to start washing clothes. Before the water inlet valve is controlled to be opened, the waterproof air-permeable valve is controlled to be closed, and the photoplasma pipe and the fan are controlled to stop running, so that the photoplasma fresh air device is prevented from being damaged due to the fact that water fed into the inner barrel through the water inlet valve enters the photoplasma fresh air device. Through such control mode, can obtain better washing effect when guaranteeing degerming effect to can also effectively avoid damaging light plasma new trend device, promote user experience.
If the current operation stage is not in the pre-water-intake stage, it is further determined whether the current operation stage is in the spin-drying stage, i.e., S204 is performed.
If the current operation stage is not in the spin-drying stage, that is, the current operation stage is not in the spin-drying stage nor in the pre-water inlet stage, which means that the mixed washing stage may be in the washing stage or the rinsing stage, etc., in this case, the outer tub is filled with the washing water, and at this time, the waterproof ventilation valve is not opened, and the operation of the light plasma tube and the fan is not controlled, that is, S205 is performed, so as to prevent the washing water in the outer tub from entering the light plasma fresh air device to damage the light plasma fresh air device.
If the current operation stage is in the spin-drying stage, which means that no washing water is basically in the outer cylinder at the moment, the waterproof air-permeable valve is controlled to be opened, that is, S206 is executed, so that the air outlet of the optical plasma fresh air device is communicated with the inner cylinder.
After controlling the waterproof and breathable valve to be opened, both the control light plasma tube and the fan are operated in a high-grade, i.e., after performing S206, S207 is performed. Therefore, more gas containing ionic substances can be sent into the inner cylinder through the light plasma tube and the fan, so that the outer cylinder, the inner cylinder and clothes in the inner cylinder can be better sterilized, and a better sterilizing effect can be obtained.
It should be noted that, the operation of the light plasma tube and the fan can be controlled while the opening of the waterproof air-permeable valve is controlled, and on the premise of not deviating from the principle of the application, a person skilled in the art can flexibly select specific occasions for controlling the operation of the light plasma tube and the fan according to specific application scenes, so long as a better degerming effect can be obtained.
In one possible embodiment, when the current operation stage is in the spin-drying stage, after controlling both the light plasma tube and the fan to operate in the high-end for a second preset time period, i.e., after performing S207 the second preset time period, for example, after the light plasma tube and the fan are operated for 15 min. At this time, the light plasma tube and the fan are operated for a long time, more gas containing ionic substances is fed into the inner cylinder, bacteria, viruses and the like on the outer cylinder, the inner cylinder and clothes are basically killed, and at this time, the light plasma tube and the fan are controlled to stop operation, so that a better sterilization effect can be obtained, and electric energy can be saved.
After S207 is executed, the operation of the light plasma tube and the fan may be controlled until the operation of the hybrid washing mode is completed. On the premise of not deviating from the principle of the application, a person skilled in the art can flexibly select specific time for controlling the light plasma tube and the fan to stop running according to specific application scenes, so long as a good degerming effect can be obtained.
In summary, when the photoplasma fresh air device is arranged below the outer cylinder and the waterproof ventilation valve is arranged between the photoplasma fresh air device and the outer cylinder, if the current operation stage is in the pre-water inlet stage, the waterproof ventilation valve is controlled to be opened, the inner cylinder is controlled to rotate, the photoplasma tube and the fan are controlled to operate, the water inlet valve is opened after the photoplasma tube and the fan are controlled to operate for a first preset time period, the drum washing machine is controlled to operate in a mixed washing mode, and the waterproof ventilation valve is controlled to be closed before the water inlet valve is opened, and the photoplasma tube and the fan are controlled to stop operating. And if the current operation stage is in the spin-drying stage, controlling the waterproof and breathable valve to be opened and controlling the light plasma tube and the fan to operate. If the current operation stage is not in the pre-water inlet stage and the spin-drying stage, the opening of the waterproof air-permeable valve and the operation of the light plasma tube and the fan are not controlled. Through the control mode, better sterilization effect can be obtained when better washing effect is obtained, the damage to the optical plasma fresh air device can be effectively avoided, electric energy is saved, and user experience is better promoted.
As shown in fig. 7, in one possible embodiment, the control method of the present invention further includes:
S300: before controlling the opening of the waterproof and breathable valve, acquiring the operation time length of a spin-drying stage;
s301: judging whether the operation time is greater than a time threshold, if so, executing S302; if not, executing S303;
s302: controlling the opening of the waterproof ventilation valve;
s303: the opening of the waterproof air-permeable valve is not controlled.
In S300, when the current operation stage is the spin-drying stage, the operation time length of the spin-drying stage is acquired before the waterproof and ventilation valve is controlled to be opened, that is, before S206 is executed.
In S301, based on the operation duration obtained in S300, it is determined whether the operation duration is greater than a duration threshold, and if the operation duration is greater than the duration threshold, for example, the operation duration of the spin-drying stage is 1 minute, and the duration threshold is 45 seconds. The spin-drying stage is operated for a period of time, most of the water remained on the clothes is spin-dried and discharged, and basically no more water is thrown out, namely no more washing water exists in the outer cylinder, and at the moment, the waterproof and breathable valve is controlled to be opened, namely S302 is executed. At the moment, the waterproof ventilation valve is opened, water does not enter the light plasma fresh air device, and the light plasma fresh air device is not damaged.
If the length of operation is less than or equal to the length of time threshold, for example, the length of operation of the spin phase is 10 seconds and the length of time threshold is 45 seconds. The fact that at the moment, the spin-drying stage just starts to run is indicated, a part of water still remains on clothes, water is thrown out, a small amount of washing water still exists in the outer cylinder, at the moment, the waterproof ventilation valve is not controlled to be opened, that is, S303 is executed, so that the washing water in the outer cylinder is prevented from entering the photoplasma fresh air device to cause damage.
Through the control mode, a better degerming effect can be obtained on the premise of avoiding damaging the light plasma fresh air device.
It should be noted that, the operation duration of the spin-drying stage may not be obtained before the waterproof and air-permeable valve is controlled to be opened, that is, S300 may not be executed before S206 is executed, but the waterproof and air-permeable valve is directly controlled to be opened after the current operation stage is determined to be the spin-drying stage, that is, when the determination result in S204 is yes, S206 is directly executed. Under such circumstances, in order to avoid damage to the photoplasma fresh air device caused by the washing water in the outer tub, the junction of the photoplasma fresh air device and the outer tub may be disposed at the upper side of the lowest part of the outer tub, so that even if there is a small amount of washing water in the outer tub, the photoplasma fresh air device will not enter into the photoplasma fresh air device.
In one possible embodiment, the photoplasma fresh air device is arranged above the outer cylinder, i.e. the air outlet of the photoplasma fresh air device is higher than the top side of the outer side wall of the outer cylinder.
A possible implementation of the control method of the present invention when the optical plasma fresh air device is disposed above the outer tub will be described below with reference to fig. 8.
As shown in fig. 8, in one possible embodiment, the control method of the present invention further includes:
