Description

Control method of laundry treating apparatus

Technical Field

The invention relates to the technical field of clothes treatment, in particular to a control method of clothes treatment equipment.

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 the inner barrel 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 system generally has a sterilization effect only on the surface of the clothes irradiated with ultraviolet rays, and the space in the inner cylinder 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.

In the technical scheme of the application, the clothes treatment equipment comprises a shell, an outer cylinder arranged in the shell and an inner cylinder arranged in the outer cylinder, wherein the inner cylinder is communicated with the outer cylinder, and the inner cylinder is arranged to be rotatable relative to the outer cylinder. The clothes treatment equipment is provided with a light plasma fresh air device, the light plasma fresh air device comprises a shell, a light plasma tube and a fan, wherein the light plasma tube and the fan are arranged in the shell, the shell is provided with an air inlet and an air outlet, the air inlet is communicated with the environment, the air outlet can be communicated with the inner cylinder, an air channel is formed between the air inlet and the air outlet, at least one part of the light plasma tube is positioned in the air channel, the fan is arranged in the shell, the light plasma tube is arranged to ionize air when being electrified so as to generate gas containing ionic substances, and the fan is arranged to introduce air in the environment into the shell through the air inlet and send the gas ionized through the light plasma tube out through the air outlet. Through the arrangement mode, under the action of the fan, air in the environment enters the shell through the air inlet, and the light plasma tube in the shell can generate hydroxyl, free oxygen atoms and superoxide ion plasma substances by separating pure oxygen and water in the air when being electrified, and then gas containing the ion substances enters the inner cylinder through the air outlet. 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, judging whether the washing mode is a fast washing mode, and controlling the light plasma tube and the fan to operate if the washing mode is the fast washing mode. Through such control mode, control the operation of light plasma tube and fan when washing mode is fast washing mode, just so also with the operation of light plasma tube and fan and fast washing mode combination, when guaranteeing to accomplish the washing of clothing fast in order to satisfy the user's demand, can better to the urceolus, inner tube and be located the clothing of inner tube and disinfect, obtain better degerming effect.

Further, before controlling the operation of the light plasma tube and the fan, the odor concentration in the inner cylinder is obtained, the odor concentration is compared with the concentration threshold value, and the operation of the light plasma tube and the fan is selectively controlled according to the first comparison result. Through the control mode, the operation of the light plasma tube and the fan is controlled according to the odor concentration in the inner cylinder, so that the operation of the light plasma tube and the fan can be controlled according to the specific conditions in the inner cylinder, and the electric energy can be saved while the sterilization effect is ensured.

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 and the outer cylinder can be communicated or not communicated through the waterproof ventilation valve. Under the condition, if the odor concentration is larger than the concentration threshold value, the condition that the odor exists in the inner cylinder at present and more bacteria, viruses and the like possibly exist is indicated, at the moment, the operation stage of the quick washing mode is acquired, whether the operation stage is a spin-drying stage is judged, and the operations of the waterproof ventilation valve, the light plasma tube and the fan are selectively controlled according to the judging result. Because the light plasma fresh air device is located below the outer cylinder, if the fast washing mode is in a stage that washing water exists in the outer cylinder such as a washing stage and a rinsing stage, at the moment, the washing water of the running light plasma fresh air device possibly enters the light plasma fresh air device, and then the light plasma fresh air device is damaged, at the moment, the running stage of the fast washing mode is required to be obtained, whether the running stage is a spin-drying stage is judged, and then the running of the waterproof ventilation valve, the light plasma tube and the fan is selectively controlled according to the judging result, so that the sterilization effect can be ensured, and the damage of the light plasma fresh air device caused by the running of the light plasma fresh air device in the stage that the washing water exists in the outer cylinder can be avoided, and therefore the user experience can be effectively improved.

If the operation stage is a spin-drying stage, the waterproof and air-permeable valve is controlled to be opened, and the operation of the light plasma tube and the fan is controlled simultaneously or after the waterproof and air-permeable valve is controlled to be opened. That is, when the operation stage is a spin-drying stage, the waterproof ventilation valve is opened, the operation of the light plasma tube and the fan is controlled, and as the outer cylinder is communicated with the inner cylinder, the inner cylinder is communicated with the light plasma fresh air device, under the action of the fan, air in the environment is introduced into the shell, and is ionized by the light plasma tube to generate gas containing ionic substances and then is sent into the inner cylinder, and the outer cylinder, the inner cylinder and clothes in the inner cylinder are sterilized, so that a good sterilization effect is obtained.

Further, after the operation of the light plasma tube and the fan is controlled for a preset period of 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 the moment, the operation of the light plasma tube and the fan is controlled to stop, so that a good sterilization effect can be obtained, and electric energy can be saved.

Further, before the waterproof and breathable 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.

If the operation stage is not the spin-drying stage, the current rapid washing mode is also in a stage that washing water exists in the outer cylinder, and if the waterproof ventilation valve is opened at the moment, the washing water possibly enters the photoplasm fresh air device, and then the photoplasm fresh air device is damaged. Then, at the moment, the waterproof ventilation valve is not controlled to be opened, the operation of the light plasma tube and the fan is not controlled, and the safety of the light plasma fresh air device is ensured.

Further, the light plasma fresh air device is arranged above the outer cylinder, and the light plasma tube and the fan are respectively provided with a high grade, a medium grade and a low grade. Under the condition, if the odor concentration is larger than the concentration threshold value, which indicates that the odor exists in the inner cylinder at present, more bacteria, viruses and the like possibly exist, at the moment, the light plasma tube and the fan are controlled to operate in a medium range until the operation of the fast washing mode is finished. Through the control mode, the light plasma tube and the fan can be operated in the whole washing process, so that the outer cylinder, the inner cylinder and clothes can be better sterilized, and a better sterilizing effect is obtained.

Detailed Description

Preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present application, and are not intended to limit the scope of the present application. Although the present application is described by taking a drum washing machine having a photoplasma fresh air device as an example, it is obviously applicable to other types of laundry treatment apparatuses such as pulsator washing machines, washing and drying machines, and the like.

The specific meaning of the above terms in the present application can be understood by those skilled in the art according to the specific circumstances.

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 application provides a control method of clothes treatment equipment, which can better kill the inner cylinder and clothes in the inner cylinder by adjusting the frequency of the light plasma tube and the rotating speed of the fan according to the type of a washing mode, and obtain better sterilization effect.

First, possible implementations of the laundry management apparatus of the present invention are explained with reference to fig. 1 to 4.

As shown in fig. 1 to 4, the drum washing machine includes a housing 1, an inner tub 2 provided in the housing 1, and an outer tub 3 provided outside the inner tub 2, the inner tub 2 being rotatable relative to the outer tub 3. 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 optical plasma fresh air device 4 further includes a control module 47, and the control module 47 can selectively control the operation of the optical plasma tube 42 and the fan 43 according to the odor concentration in the inner cylinder 2, and can also selectively control the operation of the optical plasma tube 42 and the fan 43 according to the operation stage in the fast wash mode.

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 application, the quick washing mode generally comprises a washing stage, a rinsing stage and a spin-drying stage, and more washing water is generally stored in the outer barrel 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: judging whether the washing mode is a quick washing mode;

s102: if the washing mode is the fast washing mode, the operation of the light plasma tube and the fan is controlled.

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 pattern of the drum washing machine obtained in S100, it is determined whether the washing pattern is a quick washing pattern.

In S102, based on the determination result in S101, when it is determined that the washing mode is the fast washing mode, the operation of the optical plasma tube and the fan is controlled.

Through the control mode, when the washing mode is the fast washing mode, 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 fast washing mode, the washing of clothes is ensured to be completed fast so as to meet the requirements of users, and meanwhile, the outer cylinder, the inner cylinder and the clothes positioned in the inner cylinder can be better subjected to disinfection treatment, and a better degerming effect is obtained.

As shown in fig. 6, in one possible embodiment, the control method of the present invention further includes:

s200: before controlling the operation of the light plasma and the fan, acquiring the odor concentration in the inner cylinder;

s201: comparing the odor concentration with a concentration threshold;

s202: and selectively controlling the operation of the light plasma tube and the fan according to the first comparison result.

In S200, the odor concentration in the inner tub is detected by the above-mentioned odor detection module before controlling the operation of the light plasma and the fan, i.e., before executing S102.

In S201, the odor concentration obtained in S200 is compared with the concentration threshold value.

In S202, the operation of the optical plasma tube and the fan is selectively controlled according to the first comparison result in S201.

Through the control mode, the operation of the light plasma tube and the fan is controlled according to the odor concentration in the inner cylinder, so that the operation of the light plasma tube and the fan can be controlled according to the specific conditions in the inner cylinder, and the electric energy can be saved while the sterilization effect is ensured.

Note that, the odor concentration in the inner tube may not be acquired until the light plasma and the fan are controlled to operate, that is, S200 may not be executed until S102 is executed. But directly controls the operation of the light plasma tube and the fan after judging that the washing mode is the fast washing mode.

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. 7 and 8.

As shown in fig. 7, in one possible embodiment, the control method of the present invention further includes:

s300: before controlling the operation of the light plasma and the fan, acquiring the odor concentration in the inner cylinder;

s301: judging whether the odor concentration is greater than a concentration threshold, if so, executing S303; if not, executing S302;

s302: the operation of the light plasma tube and the fan is not controlled;

s303: acquiring an operation stage of a quick washing mode;

s304: judging whether the operation stage is a spin-drying stage, if so, executing S306; if not, executing S305;

s305: the waterproof ventilation valve is not opened, and the operation of the light plasma tube and the fan is not controlled;

s306: controlling the opening of the waterproof ventilation valve;

s307: controlling the operation of the light plasma tube and the fan.

In S300, similarly to S200, the odor concentration in the inner tub is detected by the above-described odor detection module before controlling the operation of the light plasma and the fan, that is, before executing S102.

In S301, based on the odor concentration obtained in S300, it is determined whether the odor concentration is greater than a concentration threshold, and if the odor concentration is less than or equal to the concentration threshold, it indicates that there is substantially no odor in the inner cylinder, and the content of bacteria, viruses, and the like in the inner cylinder is low, and no sterilization treatment is required, and at this time, the operation of the light plasma tube and the fan is not controlled, that is, S302 is executed.

If the odor concentration is greater than the concentration threshold, it indicates that there is an odor in the inner cylinder, and there may be more bacteria, viruses, etc., and the disinfection process is needed, and at this time, the operation stage in which the fast washing mode is located is obtained, that is, S303 is executed.

In S304, based on the operation stage obtained in S303, it is determined whether the operation stage is a spin-drying stage, if not, it is indicated that the fast-washing mode may be in a washing stage or a rinsing stage, in this case, the outer tub is filled with washing water, and at this time, the waterproof ventilation valve is not opened, and the operations of the light plasma tube and the fan are not controlled, that is, S305 is performed, so as to avoid damaging the light plasma fresh air device.

If the spin-drying stage is the spin-drying stage, which indicates that the outer cylinder basically has no washing water, at the moment, the waterproof air-permeable valve is controlled to be opened, that is, S306 is executed, so that the photoplasma fresh air device is communicated with the inner cylinder.

After controlling the waterproof and breathable valve to be opened, the operation of the light plasma tube and the fan is controlled, i.e., after performing S306, S307 is performed. Therefore, the inner cylinder is communicated with the optical plasma fresh air device, air in the environment is introduced into the shell under the action of the fan, the air containing ionic substances is ionized by the optical plasma tube to generate gas, and then the gas is sent into the inner cylinder through the trigger port to sterilize the outer cylinder, the inner cylinder and clothes in the inner cylinder, so that a good sterilization effect is 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 summary, when the light plasma fresh air device is arranged below the outer cylinder, and a waterproof ventilation valve is arranged between the light plasma fresh air device and the outer cylinder, if the odor concentration in the inner cylinder is less than or equal to a concentration threshold value, the light plasma tube and the fan are not controlled to operate, and if the odor concentration in the cylinder is greater than the concentration threshold value, whether the operation stage where the quick washing mode is located is a spin-drying stage is further judged. If the fast washing mode is not in the spin-drying stage, the operation of the light plasma tube and the fan is not controlled, and if the fast washing mode is in the spin-drying stage, the waterproof ventilation valve is opened, and the operation of the light plasma tube and the fan is controlled. Through the control mode, the light plasma fresh air device can be prevented from being damaged while a good sterilization effect is ensured, and user experience is better improved.

In one possible implementation manner, controlling the operation of the optical plasma tube and the fan in S307 specifically includes: both the light plasma tube and the fan are controlled to operate in a high-end mode, i.e., the light plasma tube is controlled to operate at a high-end frequency, the fan is controlled to operate at a high-end rotating speed, for example, the light plasma tube is controlled to operate at a frequency of 8w, and the fan is controlled to operate at a rotating speed of 860 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 fast to send more gas containing ionic state substances into the inner tube, just so also can obtain better degerming effect fast in the short time. It is obvious that, in S307, both the light plasma tube and the fan may be controlled to operate in a middle or low gear, but the sterilization effect of this control mode may be reduced.

In one possible implementation manner, after the operation of the light plasma tube and the fan is controlled for a preset period of time, for example, after the light plasma tube and the fan are operated for 15 minutes, at this time, the light plasma tube and the fan have been operated for a long time, more gas containing ionic substances has been sent into the inner cylinder, and bacteria, viruses and the like on the outer cylinder, the inner cylinder and clothes have been basically killed, at this time, the light plasma tube and the fan are controlled to stop operation, so that not only can the sterilization effect be ensured, but also the electric energy can be saved.

As shown in fig. 8, in one possible embodiment, the control method of the present invention further includes:

s400: before controlling the opening of the waterproof and breathable valve, acquiring the operation time length of a spin-drying stage;

s401: judging whether the running time is greater than a time threshold, if so, executing S402; if not, executing S403;

s402: controlling the opening of the waterproof ventilation valve;

s403: the opening of the waterproof air-permeable valve is not controlled.

In S400, the operation duration of the spin-drying stage is acquired before the waterproof ventilation valve is controlled to be opened, i.e., before S306 is performed.

In S401, based on the operation duration obtained in S400, 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 5 minutes, and the duration threshold is 1 minute. 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 S402 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 1 minute. 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, S403 is executed, so that the washing water in the outer cylinder is prevented from entering the photoplasm 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, S400 may not be executed before S306 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 S304 is yes, S306 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. Based on this, 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. 9.

As shown in fig. 9, in one possible embodiment, the control method of the present invention further includes:

s502: the operation of the light plasma tube and the fan is not controlled;

s503: and controlling the light plasma tube and the fan to operate in a medium range until the operation of the fast washing mode is finished.

In S500, similar to S200 and S300, the odor concentration in the inner tub is detected by the odor detection module described above before controlling the operation of the light plasma and the fan, that is, before executing S102.

In S501, based on the odor concentration obtained in S500, it is determined whether the odor concentration is greater than or equal to the concentration threshold, and if the odor concentration is less than or equal to the concentration threshold, it is indicated that no odor is generated in the inner cylinder basically, and no disinfection treatment is needed, and at this time, the operation of the light plasma tube and the fan is not controlled, that is, S502 is executed.

If the odor concentration is greater than the concentration threshold, which indicates that there is an odor in the inner cylinder, and there may be more bacteria, viruses, etc., and the sterilization treatment is needed, at this time, the light plasma tube and the fan are controlled to operate in the middle range until the operation of the fast washing mode is finished, that is, S503 is executed. The air is ionized through the light plasma tube to generate more ionic substances, the air in the environment can be quickly introduced into the shell through the fan, the gas containing more ionic substances is quickly sent into the inner cylinder, and the clothes are sterilized, so that a better sterilizing effect is obtained.

Through the control mode, the operation of the light plasma tube and the fan is not controlled when the odor concentration in the inner cylinder is smaller, and the light plasma tube and the fan are operated in the whole fast washing mode operation process when the odor concentration in the inner cylinder is larger, so that the outer cylinder, the inner cylinder and clothes can be better sterilized, a better sterilization effect is obtained, and the electric energy consumption is reduced.

In summary, in the preferred technical scheme of the invention, when the washing mode is the fast washing mode, the operation of the light plasma tube and the fan is controlled, and the operation of the light plasma tube and the fan is combined with the fast washing mode, so that the better degerming effect can be obtained while the fast washing of clothes is ensured to be completed to meet the demands of users. When the light plasma fresh air device is arranged below the outer cylinder, if the odor concentration is greater than the concentration threshold value, judging whether the operation stage where the quick washing mode is located is a spin-drying stage, if so, controlling the waterproof ventilation valve to be opened, controlling the light plasma tube and the fan to operate, and controlling the light plasma tube and the fan to stop operating after controlling the light plasma tube and the fan to operate for a preset period of time when the operation duration of the spin-drying stage is greater than the duration threshold value; when the operation time length of the spin-drying stage is less than or equal to the time length threshold value, the opening of the waterproof ventilation valve is not controlled, and the operation of the light plasma tube and the fan is not controlled; if the stage is not the spin-drying stage, 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. By the control mode, a good sterilization effect can be obtained on the premise of avoiding damaging the light plasma fresh air device. When the light plasma fresh air device is arranged above the outer cylinder, if the odor concentration is greater than the concentration threshold value, the light plasma tube and the fan are controlled to operate in a middle-grade mode until the operation of the fast washing mode is finished, so that the light plasma tube and the fan are operated in the whole operation process of the fast washing mode, and a better sterilization effect can be obtained.
