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 and an inner cylinder arranged in the shell, wherein the optical plasma fresh air device comprises a shell and an optical plasma tube arranged in the shell, an air inlet and an air outlet are formed in the shell, 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 optical plasma tube is positioned in the air channel, and the optical plasma tube is arranged to ionize air when being electrified so as to generate gas containing ionic substances. Through the arrangement mode, 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 super-oxygen ion plasma substances by decomposing 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, the bacteria, viruses and the like in the inner cylinder and on clothes positioned 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 clothes positioned in the inner cylinder through the optical plasma fresh air device, and obtain better degerming effect.

The control method of the invention comprises the following steps: after the spin-drying procedure is finished, judging whether the clothes in the inner cylinder are taken out, and if the clothes are not taken out, controlling the inner cylinder to rotate and controlling the optical plasma fresh air device to operate. After clothes are washed and spin-dried, if the clothes are not taken out in time, peculiar smell can be generated in the clothes, at the moment, the inner cylinder is controlled to rotate, the light combining plasma fresh air device is operated, negative pressure can be formed at the air outlet through rotation of the inner cylinder, air in the environment can enter the shell through the air inlet more easily under the action of the negative pressure, then gas containing ionic substances is generated through ionization of the light plasma fresh air device, and then the gas enters the inner cylinder through the air outlet, so that the inner cylinder and the clothes in the inner cylinder are killed. In addition, the rotation of the inner cylinder can also disturb clothes, shake the clothes away, and enable the clothes to better contact with gas containing ionic substances, so that a better sterilization effect can be obtained. Through such control mode, can obtain better degerming effect, even if not in time take out the clothing after finishing washing the clothing, the peculiar smell can not appear in the clothing yet to can effectively promote user experience.

Further, the photoplasma fresh air device further comprises a fan arranged in the shell, wherein the fan is arranged to be capable of introducing air in the environment into the shell through the air inlet and sending out the gas ionized through the photoplasma tube through the air outlet. Under the action of the fan, more air in the environment can be introduced into the shell to generate more gas containing ionic substances, so that a better sterilization effect can be obtained. And 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, preventing mold and bacteria from breeding are achieved, and the user experience is effectively improved. In this case, the step of "controlling the operation of the optical plasma fresh air device" further includes: the light plasma tube is controlled to operate at a preset frequency, and the fan is controlled to operate at a preset fan rotating speed.

Further, the step of "controlling rotation of the inner barrel" specifically includes: the inner cylinder is controlled to rotate in a positive and negative alternating manner at a preset inner cylinder rotating speed. Therefore, the inner cylinder is controlled to rotate alternately in the forward direction and the reverse direction, clothes can be better disturbed, the clothes are shaken off, and the clothes are more fully contacted with gas containing ionic substances, so that a better sterilization effect is obtained.

Further, the control method of the present invention further comprises: after the light plasma fresh air device is controlled to run for a first preset time, the light plasma fresh air device is indicated to run for a period of time, at the moment, bacteria, viruses and the like on the inner cylinder and clothes are killed, and at the moment, the light plasma fresh air device is controlled to stop running. After the inner cylinder is controlled to rotate for a second preset time period in a positive and negative alternating manner at a preset inner cylinder rotating speed, the clothes in the inner cylinder are completely shaken off, the clothes are fully contacted with the gas containing ionic substances, and at the moment, the inner cylinder is controlled to stop rotating. Through the control mode, the electric energy can be saved while a good sterilization effect is obtained.

Further, whether the clothes in the inner cylinder are taken out or not is judged according to the second difference value of the second weight of the inner cylinder and the third weight of the inner cylinder after the third preset time period, if the second difference value is larger than a weight threshold value, the weight of the inner cylinder after the third preset time period is reduced more, at the moment, the clothes are judged to be taken out, and if the second difference value is smaller than or equal to the weight threshold value, the weight of the inner cylinder after the third preset time period is reduced less, and whether the clothes are taken out or not is judged further based on the humidity in the inner cylinder. If the third difference between the first humidity in the inner cylinder and the second humidity after the fourth preset time period is larger than the humidity threshold value, the difference between the humidity in the inner cylinder after the fourth preset time period and the first humidity is larger, and the clothes are judged to be taken out. If the third difference value is smaller than or equal to the humidity threshold value, the humidity in the inner cylinder after the fourth preset time period is similar to the first humidity, and at the moment, the clothes are judged not to be taken out. And whether the clothes in the inner barrel are taken out or not can be judged according to the level value of the barrel door, and if the level value of the barrel door is smaller than or equal to the level threshold value, the barrel door is in an open state, and at the moment, the clothes are judged to be taken out. If the level value of the drum door is larger than the level threshold value and the duration time is larger than or equal to the preset time, the drum door is in a closed state all the time, and at the moment, the clothes are judged not to be taken out. Through such control mode to can judge accurately whether spin-drying procedure is after the end, the clothing in the inner tube is taken out, can control inner tube rotation and the operation of light plasma new trend device more accurately based on this judgement result, thereby can prevent effectively that the clothing from producing the peculiar smell when the clothing is not in time taken out, also can not cause the waste of electric energy because of the control inner tube rotation and the operation of light plasma new trend device when the clothing has been taken out yet simultaneously.

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.

It should be noted that, in the description of the present application, terms such as "upper," "lower," "left," "right," "inner," "outer," and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are merely for convenience of description, and do not indicate or imply that the apparatus or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present application. Furthermore, it should be noted that, in the description of the present application, unless explicitly specified and limited otherwise, the terms "connected," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. 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 invention provides a control method of clothes treatment equipment, which is characterized in that when judging that clothes are not taken out after the spin-drying procedure is finished, the inner cylinder is controlled to rotate, and the optical plasma fresh air device is controlled to operate, so that the inner cylinder and the clothes positioned in the inner cylinder can be disinfected by the gas containing ionic substances generated by ionization of the optical plasma fresh air device, and the clothes are disturbed by rotation of the inner cylinder, thereby better degerming effect can be obtained, and odor of the clothes is avoided.

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.

It should be noted that, the optical plasma fresh air device 4 may not include the fan 43, and air in the environment may enter the housing 41 through the air inlet 411, be ionized by the optical plasma tube 42 to generate an ionic substance, and then enter the inner cylinder 2 through the air outlet 412. In this case, if the inner tube 2 rotates, the disturbance of air in the housing 1 is increased, and a partial negative pressure is formed in the outer tube 3, and under the action of the negative pressure, the air containing the ionic substances in the housing 41 can be sucked between the outer tube 3 and the inner tube 2, and thus the air in the environment can be induced to enter the housing 41 through the air inlet 411.

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 controls the inner drum 2 to rotate and controls the optical plasma fresh air device 4 to operate when the laundry is not taken out. The control module 47 can also determine whether or not the laundry in the inner tub 2 is taken out based on the change in the weight of the inner tub 2, whether or not the laundry in the inner tub 2 is taken out based on the change in the weight of the inner tub 2 and the change in the humidity in the inner tub 2, or whether or not the laundry in the inner tub 2 is taken out based on the magnitude of the level value of the door.

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.

Possible implementations of the control method of the laundry treating apparatus of the present application are explained 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: judging whether the clothes in the inner cylinder are taken out or not after the spin-drying procedure is finished;

s101: if the clothes are not taken out, the inner cylinder is controlled to rotate, and the optical plasma fresh air device is controlled to operate.

In S100, after the laundry is washed and spin-dried, it is determined whether the user has taken out the laundry in the drum.

In S101, based on the determination result in S100, if the determination result in S100 is that the laundry is not taken out, at this time, the inner drum is controlled to rotate, and the optical plasma fresh air device is controlled to operate. After the inner cylinder is controlled to rotate, negative pressure can be formed at the air outlet, under the action of the negative pressure, air in the environment can enter the shell through the air inlet more easily, then the air containing ionic substances is ionized by the light plasma fresh air device, and then enters the inner cylinder through the air outlet, the outer cylinder, the inner cylinder and clothes located in the inner cylinder are subjected to disinfection treatment, meanwhile, the clothes are disturbed through the rotation of the inner cylinder, and are shaken and scattered, so that the clothes are better contacted with the air containing the ionic substances, and further better sterilization effect can be obtained.

Through such control mode, can obtain better degerming effect, even if not in time take out the clothing after finishing washing the clothing, the peculiar smell can not appear in the clothing yet to can effectively promote user experience.

In one possible embodiment, the photoplasma fresh air device further comprises a fan, by which air in the environment can be introduced into the housing via the air inlet and the gas ionized via the photoplasma tube can be sent out via the air outlet. Under the condition, the steps for controlling the operation of the optical plasma fresh air device specifically comprise: the light plasma tube is controlled to operate at a preset frequency, and the fan is controlled to operate at a preset fan rotating speed. Like this, when judging that the clothing is not taken out, control light plasma tube and fan operation simultaneously, under the effect of fan, can introduce more air into the casing of light plasma new trend device to produce more gas that contains ionic state material, and send into the inner tube, disinfect the clothing of urceolus, inner tube and being located the inner tube, promote the air flow in the inner tube, thereby can prevent the clothing production peculiar smell better, promote user experience.

In the present application, the rotation speed of the fan may be a fixed value or may be increased as the frequency of the optical plasma tube increases. Of course, the fan may be operated at a low rotational speed when the weight of the laundry in the inner tub is smaller than a certain weight, and may be operated at a high rotational speed when the weight of the laundry in the inner tub is larger than the certain weight. For example, when the weight of the clothes in the inner tub is less than 3kg, the fan is operated at a rotational speed of 450r/min, and when the weight of the clothes in the inner tub is more than 3kg, the fan is operated at a rotational speed of 860 r/min. On the premise of not deviating from the principle of the application, a person skilled in the art can flexibly determine the specific rotating speed of the fan according to specific application scenes, so long as a better sterilization effect can be obtained and peculiar smell of clothes can be prevented.

It should be noted that, the optical plasma fresh air device of the present application may also not include a fan, and in this case, the steps for controlling the operation of the optical plasma fresh air device specifically include: the optical plasma tube is controlled to operate at a preset frequency. On the premise of not deviating from the principle of the application, a person skilled in the art can flexibly select a specific setting form of the optical plasma fresh air device according to specific application scenes, so long as a better degerming effect can be obtained.

A possible way of determining the frequency of the optical plasma tube according to the invention is explained below with reference to fig. 6.

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

s200: acquiring the initial weight of the inner cylinder;

s201: when judging that the clothes are not taken out, acquiring the first weight of the inner cylinder;

s202: calculating a first difference between the first weight and the initial weight;

s203: based on the first difference, a frequency of the optical plasma tube is determined.

In S200, the initial weight of the inner cylinder is obtained through the weighing module.

The initial weight of the inner tub means the weight of the inner tub when no laundry and no wash water are present. When the original parameters of the drum washing machine include the weight value of the inner drum, the weight value can be directly called as the initial weight of the inner drum.

In step S201, when it is determined in step S100 that the laundry in the inner tub is not taken out, the first weight of the inner tub is obtained by the weighing module.

In S202, based on the initial weight and the first weight obtained in S200 and S201, a first difference between the first weight and the initial weight is calculated, where the first difference is the weight of the laundry in the inner tub.

In S203, the frequency of the optical plasma tube is determined based on the first difference calculated in S202.

It should be noted that a frequency database of the light plasma tube may be constructed in advance, and frequencies of the light plasma tube corresponding to different laundry weights are stored in the frequency database. After the first difference is calculated in S203, the first difference is matched with the laundry weight in the frequency database, and the frequency of the light plasma tube corresponding to the laundry weight matched with the first difference is determined as the frequency of the current light plasma tube. Obviously, a comparison table can be constructed in advance, and the weight of the clothing in the comparison table corresponds to the frequency of the light plasma tube one by one. After the first difference is calculated in S203, the first difference is compared with the laundry weight in the frequency database, and the frequency of the light plasma tube corresponding to the same or similar laundry weight is determined as the frequency of the current light plasma tube. Of course, when the first difference is equal to or less than a certain threshold, the light plasma tube may be controlled to be operated at a lower frequency, when the first difference is greater than the threshold, the light plasma tube may be controlled to be operated at a higher frequency, for example, when the first difference is less than 5kg, the light plasma tube may be controlled to be operated at a frequency of 3w, when the first difference is greater than 5kg, the light plasma tube may be controlled to be operated at a frequency of 8w, and so on. Without departing from the principles of the present application, a person skilled in the art may flexibly determine, according to a specific application scenario, a specific manner of determining the frequency of the light plasma tube based on the first difference, so long as a better sterilization effect can be obtained, and an odor of clothing is prevented.

Through the control mode, the frequency of the light plasma tube is determined based on the actual weight of clothes in the inner cylinder, the frequency of the light plasma tube is related to the number of ionic substances generated by ionization of the light plasma tube, the greater the frequency of the light plasma tube is, the greater the number of ionic substances generated by ionization is, so that the clothes can be better disinfected, the better degerming effect is obtained, the clothes are better prevented from generating peculiar smell, and the user experience is improved.

In one possible embodiment, the frequency of the optical plasma tube increases with increasing first difference. The first difference is the weight of the clothes in the inner cylinder, that is, the frequency of the light plasma tube increases along with the weight of the clothes in the inner cylinder. That is, when the weight of the laundry is large, for example, the weight of the laundry is 8kg, the light plasma tube is controlled to operate at a large frequency, for example, the power of the light plasma is 8w. This also ionizes to form a gas containing a greater amount of ionic species and feeds the gas containing a greater amount of ionic species into the inner drum to substantially kill the outer drum, inner drum and clothing. When the weight of the clothes is small, for example, the weight of the clothes is 3kg, the light plasma tube is controlled to operate at a small frequency, for example, the power of the light plasma is 3w, so that a certain amount of ionic substances can be generated through ionization, and the gas containing the certain amount of ionic substances is sent into the inner cylinder, so that the requirements of disinfection treatment can be met. Through such control mode, the quantity of the ionic state substances in the inner barrel is adjusted according to the weight of the clothes, so that the electric energy is saved while the sterilization effect is ensured and the peculiar smell of the clothes is avoided, and the user experience can be better promoted.

In one possible embodiment, the step of "controlling the rotation of the inner barrel" specifically comprises: the inner cylinder is controlled to rotate in a positive and negative alternating manner at a preset inner cylinder rotating speed. Therefore, the inner cylinder is controlled to rotate alternately in the forward direction and the reverse direction, clothes can be better disturbed, the clothes are shaken off, and the clothes are more fully contacted with gas containing ionic substances, so that a better sterilization effect is obtained.

It should be noted that, the inner cylinder may be controlled to rotate forward or backward, and those skilled in the art may flexibly determine the specific rotation mode of the inner cylinder according to the specific application scenario without departing from the principles of the present application, so long as the clothes can be disturbed and fully contacted with the gas containing the ionic substances.

In one possible implementation manner, after the light plasma fresh air device is controlled to operate for a first preset period of time, the light plasma fresh air device is indicated to have operated for a period of time, at this time, bacteria, viruses and the like on the inner cylinder and clothes are killed, and at this time, the light plasma fresh air device is controlled to stop operating. After the inner cylinder is controlled to rotate for a second preset time period in a positive and negative alternating manner at a preset inner cylinder rotating speed, the clothes in the inner cylinder are completely shaken off, the clothes are fully contacted with the gas containing ionic substances, and at the moment, the inner cylinder is controlled to stop rotating. Through the control mode, the electric energy can be saved while a good sterilization effect is obtained.

It should be noted that the first preset duration and the second preset duration may be different or the same.

It should be noted that, the operation of the optical plasma fresh air device may be controlled to stop only after the optical plasma fresh air device is controlled to operate for a first preset period of time, or the inner cylinder may be controlled to stop rotating only after the inner cylinder is controlled to rotate alternately for a second preset period of time with a preset inner cylinder rotation speed. Of course, the operation of the optical plasma fresh air device can be stopped after the optical plasma fresh air device is controlled to operate for a first preset time period, the inner cylinder is controlled to stop rotating after the inner cylinder is controlled to rotate alternately for a second preset time period with the preset rotation speed of the inner cylinder, namely the operation of the optical plasma fresh air device and the rotation of the inner cylinder are controlled all the time, and the operation of the optical plasma fresh air device and the inner cylinder is stopped until a user takes out clothes. On the premise of not deviating from the principle of the application, a person skilled in the art can flexibly determine the operation time of the optical plasma fresh air device and the inner cylinder according to specific application scenes, so long as a better degerming effect can be obtained.

Possible implementations of the control method of the present application for judging whether the laundry in the drum is taken out after the completion of the spin-drying process are described below with reference to fig. 7 to 9.

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

s304: judging that the clothes are taken out;

s305: and judging whether the clothes are taken out or not based on the humidity in the inner cylinder.

And S300, after the spin-drying procedure is finished, acquiring the second weight of the inner cylinder through the weighing module.

In S301, after the second weight of the inner cylinder is obtained in S300 for a third preset time period, for example, the third preset time period is 2 hours, that is, after the second weight is obtained for 2 hours, the third weight of the inner cylinder is obtained by the above-mentioned weighing module.

In S302, a second difference between the second weight and the third weight is calculated based on the second weight and the third weight acquired in S300 and S301.

In S303, based on the second difference calculated in S302, it is determined whether the second difference is greater than a weight threshold, and if the second difference is greater than the weight threshold, for example, the second difference is 4kg, and the weight threshold is 0.5kg. The weight of the inner tub is reduced more after the third preset time period, and it is determined that the laundry has been taken out at this time, that is, S304 is performed.

If the second difference is equal to or less than the weight threshold, for example, the second difference is 0.3kg and the weight threshold is 0.5kg. The weight of the inner tub after the third preset time period is less reduced, and at this time, it is further determined whether the laundry is taken out based on the humidity in the inner tub, that is, S305 is performed.

When the second difference is equal to or smaller than the weight threshold, the second difference is considered to be caused by evaporation of moisture on the laundry, a weighing error, or the like, because the weight change of the inner tub is small, and it can be determined that the laundry is not taken out directly.

Through the control mode, whether the clothes in the inner cylinder are taken out can be accurately judged, and then the operation of the optical plasma fresh air device and the inner cylinder can be well controlled.

S404: judging that the clothes are taken out;

s405: and judging that the clothes are not taken out.

In S400, when it is determined in S303 that the second difference is equal to or smaller than the weight threshold, the first humidity in the inner cylinder is obtained by the humidity detection device.

In S401, after the fourth preset time period of the first humidity is acquired, for example, the fourth preset time period is 2 hours, that is, after the first humidity is acquired for 2 hours, the second humidity in the inner cylinder is acquired by the above-mentioned humidity detection device.

In S402, a third difference between the first humidity and the second humidity is calculated based on the first humidity and the second humidity acquired in S400 and S401.

In S403, based on the third difference value calculated in S402, it is determined whether the third difference value is greater than the humidity threshold, if the third difference value is greater than the humidity threshold, it indicates that the humidity in the inner cylinder after the fourth preset period of time is greater than the first humidity, and it may be that the user has re-put a new laundry, where the weight of the new laundry is similar to the weight of the laundry that has been spin-dried last time, so that the second difference value is less than or equal to the weight threshold. This means that the last spin-dried laundry has been taken out, and the laundry in the drum is a new laundry at this time, and it is determined that the laundry has been taken out, that is, S404 is performed.

If the third difference is less than or equal to the humidity threshold, which indicates that the humidity in the inner drum after the fourth preset period is similar to the first humidity, the second difference may be caused by evaporation of water on the clothes in the inner drum or due to measurement errors, and the like, at this time, it is determined that the clothes are not taken out, that is, S405 is executed.

Through the control mode, the weight change of the inner cylinder and the humidity change in the inner cylinder are comprehensively considered, so that whether clothes in the inner cylinder are taken out or not can be accurately judged, and the operation of the optical plasma fresh air device and the inner cylinder can be well controlled.

It should be noted that, the specific values of the third preset duration and the fourth preset duration are only described as an example, and those skilled in the art can flexibly select the specific values of the third preset duration and the fourth preset duration according to specific application scenarios, obviously, the values of the third preset duration and the fourth preset duration may be different or the same, so long as whether the clothes in the inner cylinder are taken out can be accurately judged.

s506: and judging that the clothes are not taken out.

S500, after the spin-drying procedure is finished, acquiring a level value of a barrel door;

in S501, based on the level value of the drum door acquired in S500, it is determined whether the level value is equal to or less than the level threshold, and if the level value is equal to or less than the level threshold, which indicates that the drum door is currently in an open state, it is determined that the laundry has been taken out, that is, S502 is executed.

If the level value is greater than the level threshold, indicating that the door is currently in a closed state, but it cannot be determined whether it is opened and closed, or is in a closed state all the time, at this time, the duration for which the level value is greater than the level threshold is acquired, that is, S503 is performed.

In S504, based on the duration acquired in S503, it is determined whether the duration is equal to or longer than a preset time, and if the duration is equal to or longer than a preset time, for example, the duration is 2.5 hours, the preset time is 2 hours, which indicates that the drum door is always in a closed state, that is, that the user does not open the drum door to take out the laundry, at this time, it may be determined that the laundry is not taken out, that is, S506 is performed.

If the duration is less than the preset time, for example, the duration is 0.5 hours, the preset time is 2 hours, which indicates that the drum door was previously opened and then closed again, that is, that the user opens the drum door halfway to take out the laundry and then closes the drum door again, at this time, it may be determined that the laundry has been taken out, that is, S505 is performed.

Through the control mode, based on the level value of the drum door and the duration time that the level value is larger than the level threshold, whether the clothes in the inner drum are taken out or not can be accurately judged, and then the operation of the optical plasma fresh air device and the inner drum can be well controlled.

In summary, in the preferred technical scheme of the invention, after the spin-drying procedure is completed, whether the clothes in the inner cylinder are taken out is judged, if the clothes are not taken out, the inner cylinder is controlled to rotate, and the optical plasma fresh air device is controlled to operate.
