Detailed Description

The present application is described in further detail below with reference to the accompanying drawings and examples.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

In order to fully exert the sterilizing and deodorizing effects of the plasmas, in various embodiments of the application, when the household electrical appliance is operated in a first mode for sterilizing and deodorizing, the heater is controlled to heat and the plasma generator is controlled to operate, so that the environment temperature of the plasma generator is in a first set temperature range, and the plasmas generated by the plasma generator sterilize and deodorize air in the first set temperature range; the first set temperature range is located between the upper temperature limit value and the lower temperature limit value, that is, the first set temperature range has a reasonable temperature interval. Because in the first set temperature range, the plasma generated by the plasma generator can not only sufficiently sterilize and deodorize the air based on the free movement of the particle swarm, but also avoid the rapid decomposition of active oxides caused by the overhigh temperature, thereby achieving the better sterilization and deodorization effects. For the plasma generators with the same power, the control method of the embodiment of the application can optimize the sterilization and deodorization effects of the plasma generators.

Before describing a control method of the home appliance, a description is given of the home appliance according to the embodiment of the present application.

In this embodiment of the present application, a home appliance includes: a heater for heating and a plasma generator for generating a plasma. The heater may be an electrothermal heating tube, a resistance wire or a similar heating device, and may directly or indirectly heat the environment where the plasma generator is located, for example, the heater may directly heat the environment where the plasma generator is located, or the heater may transfer heat to the environment where the plasma generator is located through a heat conducting medium (which may be in a gaseous state, a liquid state or a solid state, etc.), which is not limited in this application.

Illustratively, the plasma generator may employ a structure capable of directly ionizing air in which the plasma generator is located, the structure of which will be described in detail below.

The home appliance may be, for example, a laundry treatment apparatus, a dishwasher, an air cleaner, or the like.

In an application example, the home appliance is a laundry treatment device, and the plasma generator of the embodiment of the present application can sterilize and deodorize air in the tub to improve the laundry treatment effect. Illustratively, the laundry treating apparatus includes a tub and a drying tunnel in communication with the tub, and a plasma generator may be disposed in the drying tunnel to ionize air flowing through the drying tunnel to generate plasma. The heater may also be disposed within the drying tunnel to heat air flowing through the drying tunnel. Here, the laundry treating apparatus may be a clothes dryer or a washing and drying integrated machine having a drying function.

As shown in fig. 1, a control method of a home appliance according to an embodiment of the present application includes:

step 101, controlling the household appliance to start a first mode for sterilization and deodorization; in a first mode, controlling the heater to heat and the plasma generator to operate, so that the environment temperature of the plasma generator is in a first set temperature range, and the plasma generated by the plasma generator sterilizes and removes the odor of the air in the first set temperature range; the first set temperature range is located between the upper temperature limit and the lower temperature limit.

For example, the home device may receive indication information of the user through a man-machine interaction interface, and initiate the first mode based on the indication information, for example, the man-machine interaction interface may include a key, a touch screen, a standard wired interface or a wireless interface, and the user may implement information interaction with the home device through a local input, a remote control, a voice, an APP (application program) or the like, and the home device initiates the first mode based on an instruction indicating that the first mode is initiated.

It should be noted that the first mode may be an independent processing procedure, or may be a processing procedure in a certain processing procedure, for example, the first mode may also be a processing procedure of a laundry processing apparatus, so as to sterilize and deodorize the processed laundry, or the first mode may also be a processing procedure of a dish washing procedure of a dish washer, so as to sterilize and deodorize the washed dish. For example, the home appliance may start the first mode based on the operation phase of the program, for example, the laundry treating apparatus may start the first mode after determining that the washing is finished based on the laundry treating program.

In this embodiment of the present application, because in the first set temperature range, the plasma generated by the plasma generator can not only be based on the free movement of the particle swarm, but also can avoid the too fast decomposition of the active oxide caused by the too high temperature, thereby achieving the better sterilizing and deodorizing effects.

It will be appreciated that in the first mode, control of the heater heating and the plasma generator to operate together may be based on having the plasma generated by the plasma generator operate within a first set temperature range. Because when the plasma temperature is too high, the decomposition of active oxides in the plasma is accelerated, but along with the temperature rise, the diffusion of the plasma is facilitated, the free movement of particle groups of the plasma is accelerated, and the plasma generator can be effectively sterilized and deodorized.

In some embodiments, the first set temperature range is 30 ℃ to 50 ℃, i.e. in the first mode, the heater is controlled to work, so that the environment temperature of the plasma generator is in the range of 30 ℃ to 50 ℃, and the sterilization and deodorization effect of the plasma generator is better than that of the plasma generator without a heating function when the plasma generator works alone.

In some embodiments, the first set temperature range is preferably 40 ℃ to 50 ℃. Through test, the decomposition speed of the plasma is obviously accelerated in the environment temperature of more than 50 ℃, the free movement speed of particle groups is effectively accelerated in the environment temperature of more than 40 ℃, and when the plasma generator works at the environment temperature of 40-50 ℃, the sterilization and deodorization effect of the plasma generated by the plasma generator is better.

For example, a household appliance with a plasma generator is tested, and the corresponding sterilization effects in three scenes of the environment temperature of the plasma generator being above 60 ℃, 40-50 ℃ and the non-intervention environment temperature are respectively tested, three sets of test data (A, B, C sets of test data respectively) are respectively obtained in each scene, and the test data are shown in the following tables 1 and 2:

TABLE 1

TABLE 2

The number of original colonies before sterilization in each scene was 4000, and the sterilization rate= (1-number of residual colonies/number of original colonies) ×100%. By combining the above tables 1 and 2, it was confirmed that the plasma generator produced plasma with a better sterilizing and deodorizing effect, since the number of residual colonies per group was the least and the sterilizing rate was the highest when the plasma generator was operated at an ambient temperature of 40 to 50 ℃.

Illustratively, in the first mode, the heater is controlled to heat and the plasma generator is controlled to operate, and the heater and the plasma generator can be controlled to start synchronously; or the heater is controlled to heat first, so that the plasma generator is controlled to start after the ambient temperature of the plasma generator reaches a first set temperature range; or may be to control the plasma generator to start before the heater. It will be appreciated that in the case where the plasma generator and the heater are activated simultaneously or the plasma generator is activated prior to the heater, if the initial ambient temperature is not within the first set temperature range, the sterilization and deodorization effects of the plasma generated at the initial stage of the plasma generator may be affected.

In some embodiments, controlling heater heating and plasma generator operation includes:

controlling a heater to heat;

and determining that the ambient temperature of the plasma generator is in a first set temperature range, and controlling the plasma generator to start and operate.

It can be understood that, because the heater is started to heat first, the environment temperature where the plasma generator is located is in the first set temperature range, and then the plasma generator is controlled to start and operate, so that the plasmas generated by the whole process of the plasma generator have better sterilizing and deodorizing effects. Here, the home appliance may provide at least one temperature sensor for monitoring an ambient temperature at the plasma generator, and determine whether the ambient temperature at which the plasma generator is located is in a first set temperature range based on the temperature detected by the temperature sensor. For example, since the ambient temperature tends to rise gradually when the heater heats, the home appliance determines that the ambient temperature reaches the lower limit value of the first set temperature range based on the temperature detected by the temperature sensor, and starts and operates the plasma generator, so that the start-up delay of the plasma generator in the first mode can be reduced.

Illustratively, as shown in fig. 2, after step 101, the control method according to the embodiment of the present application further includes:

step 102, controlling the plasma generator to stop running so as to exit the first mode;

step 103, controlling the household appliance to start a second mode for eliminating residual plasmas; in a second mode, controlling the heater to heat so that the environment temperature of the plasma generator is in a second set temperature range; wherein the second set temperature range is greater than or equal to the preset temperature.

Here, the home appliance controls the plasma generator to stop operating, exit the first mode, and then start and operate the second mode, and in the second mode, the heater heats to enable the ambient temperature of the plasma generator to be located in the second set temperature range, so that residual plasmas can be eliminated, for example, the decomposition of residual active oxides is quickened, and the influence of the residual active oxides on users is avoided.

The preset temperature is, for example, 50 ℃, i.e. the second set temperature range is greater than or equal to 50 ℃. It is understood that as the temperature increases, the decomposition rate of the active oxide increases, but the excessive temperature may affect components of the home appliance, etc., so that the second set temperature range may be controlled below a reasonable upper limit temperature, for example, the second set temperature range may be greater than 50 ℃ and less than or equal to 65 ℃.

Illustratively, controlling the plasma generator to cease operation includes:

Here, the operation duration of the first mode may be determined based on timing of the moment when the first mode is started. The operation duration of the first mode can also be determined based on timing of starting the plasma generator, so as to count the duration after the plasma generator is started, and if the determined duration reaches the first set duration, the power supply of the plasma generator is disconnected, and the first mode is exited.

Here, the first set period may be determined based on the user indication information, or may be determined based on a load weight detected by the home appliance (such as a weight of laundry to be treated), or may be determined based on a default parameter, which is not limited in this application.

Illustratively, controlling operation of the plasma generator includes:

and controlling the plasma generator to circularly work based on the set on-off ratio, wherein the set on-off ratio is the ratio of the running duration to the stopping duration in one period.

It will be appreciated that controlling the plasma generator to operate cyclically based on a set on-off ratio, for example, by first operating for m seconds and then stopping for n seconds during a duty cycle T, and cyclically operating according to the duty cycle T, where t=m+n, where m and n are integers greater than zero, and where the values of m and n can be reasonably determined according to a test, and where T is less than 30 seconds, for example. The intermittent ionization air of the plasma generator can be caused, and the phenomenon that the temperature is too high due to the fact that the electrodes of the plasma generator continuously work is avoided, so that the service life of the electrodes is influenced.

Illustratively, as shown in fig. 2, the control method according to the embodiment of the present application further includes:

step 104, determining that the operation duration of the second mode reaches a second set duration, and controlling the heating device to be powered off.

Here, the second set period may be preset based on a test to meet the requirement of decomposing the residual plasma, so that no plasma remains in the working chamber or the residual plasma is negligible. Thus, the user turns on the home appliance, and the residual plasma does not affect the user.

It will be appreciated that when controlling the heater heating, the heater heating may be controlled based on a feedback control algorithm, such as a Proportional Integral Derivative (PID) algorithm, such that the ambient temperature of the plasma generator is within a first set temperature range or a second set temperature range; the operating state of the heater may be controlled based on the temperature peak value, for example, taking the case that the ambient temperature of the plasma generator is within the first set temperature range as an example, based on the temperature value reflecting the ambient temperature detected by the temperature sensor, if the temperature value is determined to be greater than the upper limit value of the first set temperature range, heating of the heater is stopped, and if the temperature value is determined to be less than the lower limit value of the first set temperature range, heating of the heater is controlled to be resumed, and the cycle is thus repeated. The above is merely an example, and the control of the heater is not limited in the present application, as long as the ambient temperature of the plasma generator is made to satisfy the set requirement.

Illustratively, as shown in fig. 3 to 5, the plasma generator of the embodiment of the present application includes: the tube body 1, the lead wire 2, the conductive coil 3 and a power circuit (not shown in the figure), wherein the tube body 1 is filled with a conductive medium 4, for example, the tube body 1 can be filled with a conductive medium such as graphite, water and the like. Illustratively, the tube body 1 is filled with graphite, that is, the conductive medium 4 is graphite, and the conductive wire 2 is disposed in the graphite, and one end extends out of the tube body 1 to form a connection end connected with a power circuit. Because graphite has high temperature resistance, toughness and conductivity, the graphite is convenient to fill in the pipe body 1 and is electrically connected with the lead 2, and the graphite has good stability and long service life. The tube body 1 is made of an insulating material, for example, the tube body 1 may be a Quartz tube (Quartz tube), a glass tube, a ceramic tube, or the like. The wire 2 may be a metal wire, the wire 2 being located in a conductive medium 4 inside the tube body 1 as a first electrode (also called inner electrode) of the plasma generator. The conductive coil 3 is wound on the outer wall surface of the tube body 1 as a second electrode (also referred to as an external electrode) of the plasma generator. The power supply circuit is used for supplying power to the wire 2 and the conductive coil 3, i.e. to the first electrode and the second electrode. Here, the power supply circuit has a first terminal for supplying power and a second terminal, the first terminal is electrically connected to the wire 2, the second terminal is electrically connected to the conductive coil 3, and the conductive coil 3 and the wire 2 ionize air outside the tube body 1 by an output voltage of the power supply circuit to generate plasma.

It will be appreciated that, due to the high operating voltage of the plasma generator, the power supply circuit needs to boost the input power (e.g. 220V mains supply) to convert the input power into an output voltage corresponding to the voltage required for ionizing air, and output the output voltage to the wire 2 via the first terminal and the conductive coil 3 via the second terminal. The conductive coil 3 and the wire 2 ionize air under high voltage to generate plasma 5 (as shown in fig. 5).

In the embodiment of the application, the conducting wire 2 serving as the inner electrode is arranged in the pipe body 1, the conducting coil 3 serving as the outer electrode is arranged outside the pipe body 1, the conducting coil 3 and the conducting wire 2 ionize air outside the pipe body 1 under the action of the output voltage of the power supply circuit to generate the plasma 5, and the air in the environment where the plasma generator is located can be ionized directly, so that the sterilization and deodorization effects are realized, and the application to household appliances with limited installation space is facilitated; in addition, wire discharge based on a dielectric barrier discharge principle is formed between the conductive coil 3 and the wire 2, so that air is easily ionized, more active oxides can be generated, particularly, in the air with relatively high humidity, water is easily decomposed into active substances such as hydroxyl free radicals, and the like, and meanwhile, various active oxides (such as ozone, oxygen ions and the like) and ultraviolet rays can be generated by ionized air, so that the effects of sterilization, disinfection and air deodorization are facilitated.

It will be appreciated that the conductive coil 3 is exposed to air and is prone to wire discharge, thereby facilitating ionization of the air, particularly in relatively high humidity air, to decompose water into active substances such as hydroxyl radicals, and the like, and that ionization of the air may produce various active oxides including ozone, oxygen ions, and the like, and ultraviolet rays. Taking an example that the plasma generator is applied to the laundry treating apparatus, since the inside of the laundry treating apparatus is in a high-humidity environment during operation, the plasma generated by ionizing air in the high-humidity environment by the plasma generator may include: high-energy electrons, ozone, oxygen ions, ultraviolet rays, hydroxyl radicals and the like, so that the adhesive hydroxyl radicals can be generated, the sterilization, disinfection and deodorization effects are promoted, and compared with a plasma generator with a ceramic sheet structure, the sterilization and deodorization effects of plasmas can be effectively improved. In addition, the conductive coil 3 has an enhanced oxidation resistance compared with the electrode of the panel discharge due to the wire discharge, so that the plasma generation amount of the plasma generator is stable in a longer working time, and the reliability of the plasma generator is enhanced.

The conductive coil 3 is illustratively helical and is distributed on the tube 1 in the axial direction of the tube 1. The spiral-shaped conductive coil 3 can here form a wire-discharge effect over a larger area, thereby ionizing the air over a larger area. Preferably, the conductive coils 3 are distributed at equal intervals in the axial direction of the tube body 1, so that the electric field is more uniform, and the wire discharge effect is better.

Illustratively, a sealed chamber is formed within the tube body 1, and the wire 2 extends partially out of the chamber (as shown in fig. 3 and 4) to form a connection terminal for electrical connection with the first terminal. In this way, a reliable connection of the first terminal of the power supply circuit to the wire 2 can be achieved.

Illustratively, the outer layer of the conductive coil 3 is coated with an oxidation resistant coating. Here, the oxidation-resistant coating may be formed on the outer layer of the conductive coil 3 by using a plasma sputtering, chemical deposition, electroplating or metal powder sintering process, and the conventional mature technologies may be used for the plasma sputtering, chemical deposition, electroplating and metal powder sintering processes, which will not be described herein. The coating may be an electrocatalytic oxide layer, such as IrCo (Ir cobalt oxide) or TiO ₂ As long as the wire coil 3 is not oxidized for a long period of time, the titanium dioxide is not particularly limited in this application. It should be noted that, the electrocatalytic oxide layer is used as a coating layer, which can enhance the antioxidation capability of the conductive coil 3, and also can promote the generation of plasma based on the wire discharge of the dielectric barrier discharge principle, thereby enhancing the sterilizing and disinfecting effects and/or the air deodorizing effects on the environment.

In this embodiment, the conductive wire 2 or the conductive coil 3 may be made of metal such as copper, aluminum, titanium, etc. Preferably, the lead wire 2 and the conductive coil 3 are made of titanium with strong corrosion resistance and oxidation resistance, so that the working reliability of the plasma generator can be further enhanced.

In some embodiments, the plasma generator further comprises: the timing control circuit is connected with the power supply circuit and is used for controlling the power supply circuit to work circularly based on the set on-off ratio, and the on-off ratio is set to be the ratio of the running duration to the stopping duration in one period.

It will be appreciated that the power supply circuit may be operated cyclically under control of the timing control circuit based on a set on-off ratio, for example, during a duty cycle T, the power supply circuit of the plasma generator may be operated for m seconds and then stopped for n seconds, and operated cyclically according to the duty cycle T, where t=m+n, m and n are integers greater than zero, and the values of m and n may be determined reasonably according to the test, and T is illustratively less than 30 seconds. Therefore, the first electrode and the second electrode of the plasma generator can be enabled to intermittently ionize air, and the situation that the first electrode and the second electrode continuously work to cause too high temperature is avoided, so that the service lives of the first electrode and the second electrode are influenced. The timing control circuit may be a timer cooperating with the power supply circuit, i.e. controlling the working state of the power supply circuit based on the hardware circuit.

In some embodiments, the plasma generator further comprises: and the controller is connected with the power supply circuit and is used for controlling the power supply circuit to work circularly based on the set on-off ratio, and the on-off ratio is set to be the ratio of the running duration to the stopping duration in one period. The controller may share a control board of the home appliance or be separately provided.

The controller may control the power supply circuit to operate cyclically based on the set on-off ratio based on the control program, for example, in a working period T, the power supply circuit of the plasma generator may be operated for m seconds first, then stopped for n seconds, and operate cyclically according to the working period T, where t=m+n, where m and n are integers greater than zero, where the values of m and n may be reasonably determined according to a test, and T is typically less than 30 seconds. Therefore, the first electrode and the second electrode of the plasma generator can be enabled to intermittently ionize air, and the situation that the first electrode and the second electrode continuously work to cause too high temperature is avoided, so that the service lives of the first electrode and the second electrode are influenced. The controller may control the duty cycle of the power circuit alone or in combination with a relay. The method avoids overhigh temperature caused by continuous operation of the first electrode and the second electrode, and is beneficial to enhancing the working reliability of the plasma generator.

It can be appreciated that the controller can adjust the duty cycle of the power circuit, i.e., adjust the ratio of the running time to the stopping time in one cycle, based on the control requirement, so as to meet the plasma generation requirements of different scenes. Therefore, the working overheat of the electrode of the plasma generator can be effectively avoided, and the plasma quantity required by different programs and different loads can be better matched.

Illustratively, the controller determines the set on-off ratio based on an operating parameter indicative of the amount of plasma generated.

Here, the operation parameter is an operation parameter directly indicating the plasma generation amount or an operation parameter indirectly indicating the plasma generation amount. For example, the working parameters can be load, a working mode corresponding to a scene or a stage where a program is located, and the like, so that the on-off ratio can be flexibly adjusted and set based on the working parameters to adjust the quantity of plasmas generated by the plasma generator, and corresponding control requirements are met.

In an application example, taking an application of the plasma generator to the laundry treatment apparatus as an example, the controller may acquire a laundry load amount of the laundry treatment apparatus, and adjust the set on-off ratio according to the magnitude of the laundry load amount, where the set on-off ratio may be positive compared to the laundry load amount, that is, the set on-off ratio increases as the laundry load amount increases.
