Description

Technical Field

[0001] The present application relates to, but is not limited to, the technical field of household appliances, and specifically refers to a water receiving device, electrical equipment, and a control method and control device thereof. Background Art

[0002] Currently, components such as the water collection area and evaporator of air conditioners and dehumidifiers are exposed to humidity for extended periods, which can easily lead to the accumulation of microorganisms (bacteria and fungi), causing contamination. In particular, the air conditioner's water collection area (i.e., the drain pan) is inaccessible and difficult to clean, leading to the accumulation of dust and microbial contaminants. These issues can cause odors and contribute to a variety of health issues, including respiratory illnesses.

[0003] Common solutions include: 1) using antibacterial and mildew-proof materials for water-receiving parts; 2) installing ultraviolet lamps and other microbial killing devices inside the body; 3) filtering out dust and bacteria at the front end; and 4) using chemicals for cleaning.

[0004] Currently, these methods each have their own shortcomings:

[0005] The effectiveness of antibacterial and anti-mildew materials is limited and cannot completely prevent the growth of bacteria and mold. In addition, this method cannot deal with the situation after the growth of microbial contaminants.

[0006] Ultraviolet light only kills bacteria where it is irradiated, but the internal structure of the air conditioner is complex, so it is difficult for ultraviolet light to reach all corners with sufficient intensity. Excessive light intensity can also cause aging of internal parts.

[0007] The primary filter can only filter large-size pollutants and has no filtering effect on particulate matter, bacteria, fungi, etc.; adding a HEPA filter will cause excessive wind resistance and is not suitable for actual use;

[0008] Regular cleaning of chemicals is complex and requires manual intervention and even disassembly of the machine, which places high demands on the professionalism of the operators. Summary of the Invention

[0009] The technical problem to be solved by this application is to provide a water receiving device that can use electrolysis of condensed water to remove dirt and mildew from water receiving components and components inside the fuselage such as the evaporator. It can handle the growth of bacteria and fungi and the formation of stubborn dirt without causing excessive wind resistance or aging of internal parts. It has a wide range of applications and does not require human intervention.

[0010] The technical solution for solving the above-mentioned technical problems in the embodiments of the present application is as follows: a water receiving device, comprising: a water receiving component; and a water electrolysis device, comprising a power supply and an anode and a cathode electrically connected to the power supply; the anode and the cathode are at least partially arranged in the water receiving component, and are configured to electrolyze water to generate bubbles so as to utilize the bubbles to promote the fall-off of dirt attached to the inner wall surface of the water receiving component.

[0011] The water receiving device provided in the embodiment of the present application can use the electrolysis of condensed water to remove dirt and mildew from the water receiving components, evaporator and other internal components of the fuselage. When the power supply applies voltage to the anode and cathode, strong oxidants such as oxygen, ozone and other active oxygen are precipitated at the interface between the anode and the condensed water, and hydrogen can be precipitated at the interface between the cathode and the condensed water. Therefore, the anode and cathode can electrolyze the condensed water in the water receiving component to generate a large number of bubbles. The bubbles generated can loosen, peel off and remove stubborn stains, bacterial colonies and other dirt attached to the inner wall of the water receiving component through mechanical force, and the detached pollutant residues can be discharged with the condensed water, thereby cleaning the water receiving component. In addition, the generated gas can overflow the water surface and diffuse into the interior of the fuselage. The small amount of ozone in the mixed gas can sterilize and inhibit bacteria in the internal components such as the evaporator above the water receiving component. Since the content of the generated ozone is limited, it will not cause pollution to the room.

[0012] Therefore, the water receiving device provided in the embodiment of the present application can truly achieve self-cleaning of difficult-to-reach areas inside the fuselage, such as the water receiving tray, and can prevent and disinfect microbial contaminants in all directions and without dead ends for other parts inside the fuselage through gaseous sterilization factors.

[0049] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0050] like Figure 1 and Figure 3 As shown, an embodiment of the present application provides a water receiving device 100, comprising: a water receiving component 1 and a water electrolysis device.

[0051] like Figure 4 As shown, the water receiving component 1 can be located below the evaporator 5 of an electrical device such as an air conditioner or a dehumidifier to collect condensed water dripping from the evaporator 5. The water receiving component 1 can be a water receiving tray, a water receiving bucket or other structural forms.

[0052] The water electrolysis device includes a power source 4 and an anode 2 and a cathode 3 electrically connected to the power source 4. The anode 2 and the cathode 3 are at least partially disposed within the water receiving component 1 and are configured to electrolyze water to generate bubbles to facilitate the removal of dirt attached to the inner wall surface of the water receiving component 1.

[0053] The reaction equation of the reaction at anode 2 is as follows:

[0054] 2H2O→O2+4H + +4e - ;

[0055] 3H2O→O3+6H + +6e - .

[0056] The cathode 3 is a hydrogen evolution electrode, and the reaction equation is as follows:

[0057] 2H + +2e - →H2.

[0058] The main reactions occurring at anode 2 are the oxygen evolution reaction and the ozone release reaction, which compete with each other. Since the half-reaction potential for ozone production (E0 = 1.51V) is higher than the half-reaction potential for oxygen production (i.e., oxygen evolution) (E0 = 1.23V), and thus less likely to occur, the primary product at anode 2 is oxygen, allowing the ozone concentration to be controlled. Furthermore, some of the generated gas will dissolve in the condensed water. For these reasons, the overflowed gas only accumulates to a certain concentration within the fuselage, and the concentration can be well controlled within a relatively large indoor space.

[0059] The water receiving device 100 provided in the embodiment of the present application can use the electrolysis of condensed water to remove dirt and mold from internal components of the water receiving component 1, evaporator 5, etc. When the power supply 4 applies voltage to the anode 2 and cathode 3, strong oxidants such as oxygen, ozone, and other active oxygen species are released at the interface between the anode 2 and the condensed water, and hydrogen can be released at the interface between the cathode 3 and the condensed water. Therefore, the anode 2 and cathode 3 can electrolyze the condensed water in the water receiving component 1, generating a large number of bubbles. The generated bubbles can loosen, peel off, and remove stubborn stains, bacterial colonies, and other contaminants attached to the inner wall of the water receiving component 1 through mechanical force. The detached contaminant residues can be discharged with the condensed water, thereby cleaning the water receiving component 1. In addition, the generated gas can overflow the water surface and diffuse into the interior of the fuselage. The small amount of ozone in the mixed gas can sterilize and inhibit bacteria in internal components such as the evaporator 5 above the water receiving component 1. Since the amount of ozone generated is limited, it will not cause indoor pollution.

[0060] Therefore, the water receiving device 100 provided in the embodiment of the present application can truly achieve self-cleaning of the water receiving tray and other parts inside the fuselage that are difficult to reach, and can prevent and disinfect microbial contaminants in all directions and without dead ends for other parts inside the fuselage through gaseous sterilization factors.

[0061] In some exemplary embodiments, the anode 2 and the cathode 3 are configured as membrane electrodes, such as Figure 1 and Figure 2 As shown, the membrane electrode is at least partially arranged on the inner wall surface of the water receiving component 1.

[0062] The anode 2 and cathode 3 are in the form of membrane electrodes, which take up less space and basically have no impact on the volume of the water receiving component 1. It is also convenient to increase the area of ​​the membrane electrode as needed so that the membrane electrode can cover as much area of ​​the water receiving component 1 as possible to improve the self-cleaning effect of the electrical equipment.

[0063] Furthermore, the membrane electrode is attached to the inner wall surface of the water receiving component 1 and can form an integrated structure with the water receiving component 1 without the need for drilling holes or setting up other additional fixing structures.

[0064] In some exemplary embodiments, the membrane electrode comprises a base layer 71 provided on the inner wall surface of the water receiving component 1 and a surface layer 72 provided on the surface of the base layer 71, such as Figure 2 shown.

[0065] The base layer can be made of relatively low-priced conductive materials, such as metal materials, to ensure that the membrane electrode has good conductivity and a certain thickness, which is conducive to reducing the cost of the membrane electrode.

[0066] The surface layer 72 can be made of relatively expensive electrode materials, which is beneficial to promoting the occurrence of electrolysis reaction and improving the electrolysis performance of the electrolysis device, so as to ensure that the water electrolysis device has a better electrolysis effect.

[0067] Of course, the membrane electrode is not limited to the structural form of the base layer 71 and the surface layer 72, and may also include only one layer or three or more layers, as long as it can electrolyze water to perform a cleaning function.

[0068] In some embodiments, the base layer 71 may be a strip-shaped metal film, which may be formed on the inner wall surface of the water receiving component 1 by electroplating, sputtering, or other processes. The water receiving component 1 may be a plastic component. Then, a surface layer 72 is formed on the strip-shaped metal film by coating or deposition, so that two mutually isolated strip-shaped conductive films are formed on the inner wall surface of the water receiving component 1, such as Figure 3 As shown, the two strip-shaped conductive films can be parallel to each other and spaced apart. The two strip-shaped conductive films are electrically connected to the positive electrode and the negative electrode of the power supply 4 respectively.

[0069] The surface layer 72 of the anode 2 may be made of an electrode material having a relatively high oxygen evolution overpotential, such as α-PbO 2 , β-PbO 2 , glassy carbon (ie, glassy carbon), Pt, boron-doped diamond, and the like.

[0070] The surface layer 72 of the cathode 3 is made of hydrogen evolution electrode material, such as stainless steel, Pt, C, Ni, Pt plating, etc. The Pt plating layer refers to a precious metal plating layer mainly composed of platinum prepared on the surface of the base material by electrolysis.

[0071] In some exemplary embodiments, at least a portion of the membrane electrode is disposed on the inner bottom wall of the water receiving component 1, such as Figure 1 and Figure 3 shown.

[0072] Since condensed water tends to settle at the bottom of the water receiving component 1 under the action of gravity, and contaminants such as bacteria and stains also tend to adhere to the bottom of the water receiving component 1 under the action of gravity, the inner bottom wall of the water receiving component 1 is the most contaminated part. Therefore, at least a portion of the membrane electrode is disposed on the inner bottom wall of the water receiving component 1, which can effectively clean the inner bottom wall of the water receiving component 1 and significantly improve the cleanliness of the water receiving component 1.

[0073] The membrane electrode can be completely arranged on the inner bottom wall of the water receiving component 1, and can cover most of the inner bottom wall as much as possible, such as Figure 3 As shown, the structure of the membrane electrode is relatively regular and easy to process and shape. Alternatively, a portion of the membrane electrode can also be arranged on the inner side wall of the water receiving component 1, which can also have a good cleaning effect on the inner side wall of the water receiving component 1.

[0074] In some exemplary embodiments, the power supply 4 is a low-voltage DC power supply, and the voltage of the low-voltage DC power supply is less than or equal to 36V.

[0075] In this way, the water receiving device 100 provided in the embodiment of the present application can use a low-voltage DC power supply to drive the electrolysis of condensed water to remove dirt and mildew inside the fuselage, which is safe and effective and will not cause harm to the human body and the fuselage.

[0076] like Figure 4 As shown, the embodiment of the present application further provides an electrical device, comprising: an evaporator 5 and a water receiving device 100 as in any of the above embodiments. The water receiving component 1 of the water receiving device 100 is configured to collect condensed water dripping from the evaporator 5 .

[0077] The electrical equipment provided in the embodiment of the present application includes the water receiving device 100 of any one of the above embodiments, and thus has all the above beneficial effects, which will not be described in detail here.

[0078] In some exemplary embodiments, the electrical device may be, but is not limited to, an air conditioner or a dehumidifier.

[0079] The electrical device may also include a housing, with the evaporator 5 located within the housing. For air conditioners, the water receiving component 1 is a water tray, which can be located within the housing. For dehumidifiers, the water receiving component 1 can be connected to the housing, forming part of the exterior. For split-type air conditioners, the evaporator 5 can be the indoor heat exchanger.

[0080] The evaporator 5 may comprise a plurality of interconnected sub-heat exchangers, such as Figure 4 As shown. The evaporator 5 can also be partially inserted into the water receiving component 1, as shown. Figure 4 shown.

[0081] An air conditioner can include a compressor, condenser, throttling device, and evaporator, all connected in sequence, forming a refrigerant cycle. The evaporator can be located indoors, serving as an indoor heat exchanger; the condenser is located outdoors, serving as an outdoor heat exchanger. Furthermore, the refrigerant can be switched between heating and cooling modes. Condensate in the indoor unit is primarily produced in cooling mode.

[0082] A dehumidifier can also include a compressor, a condenser, a throttling device, and an evaporator connected in sequence to form a refrigerant cycle. However, the condenser and evaporator can both be located indoors. After entering the dehumidifier, indoor air can flow through the evaporator and condenser in sequence before exiting.

[0083] The present application also provides a control method for the electrical equipment as described above. Figure 5 As shown, the control method includes:

[0084] Step S202: Determine to enter the self-cleaning mode;

[0085] Step S204: Start the water electrolysis device.

[0086] The control device provided in the embodiment of the present application can start the electrolysis water device after determining to enter the self-cleaning mode, and perform mechanical sterilization and mildew removal and other cleaning treatments on the water-connecting component 1 by electrolyzing condensed water to generate bubbles, and perform sterilization, antibacterial and other purification treatments on the evaporator 5 and other components inside the body by electrolyzing water to generate trace ozone, thereby improving the hygiene of the electrical equipment and benefiting the health of the user.

[0087] In some exemplary embodiments, after starting the water electrolysis device, the control method further includes:

[0088] Determine whether the electrolysis intensity of the water electrolysis device meets the set conditions;

[0089] Based on the electrolysis intensity of the water electrolysis device meeting the set conditions, the water electrolysis device is controlled to operate for the first set time according to the current working parameters and exit the self-cleaning mode.

[0090] The electrolysis intensity of the water electrolysis device is positively correlated with the amount of bubbles and ozone generated. Therefore, after starting the water electrolysis device, it is first determined whether the electrolysis intensity of the water electrolysis device meets the set conditions to avoid the electrolysis intensity of the water electrolysis device being too weak, resulting in wasted power consumption and poor cleaning effect. When it is determined that the electrolysis intensity of the water electrolysis device meets the set conditions, the water electrolysis device can be controlled to operate for a first set time according to the current operating parameters to perform self-cleaning on the water receiving component 1, the evaporator 5 and other components inside the fuselage.

[0091] The first set time can be, but is not limited to, within the range of 10 minutes to 20 minutes, such as 10 minutes, 12 minutes, 15 minutes, 20 minutes, etc. If the treatment time is too long, the condensed water temperature will rise too high; if the treatment time is too short, the decontamination and sterilization capabilities will be insufficient.

[0092] In some exemplary embodiments, Figure 6 As shown, judging whether the electrolysis intensity of the water electrolysis device meets the set conditions includes:

[0093] Obtaining the current density of the anode 2 and / or cathode 3;

[0094] Determine whether the current density of the anode 2 and / or cathode 3 is within a set current density range;

[0095] Based on the current density of the anode 2 and / or the cathode 3 being within the set current density range, it is determined that the electrolysis intensity of the water electrolysis device meets the set conditions.

[0096] The current density at the anode 2 and / or cathode 3 can directly characterize the electrolysis intensity of the water electrolysis device. Therefore, by determining whether the current density at the anode 2 and / or cathode 3 is within the set current density range, it is possible to effectively determine whether the electrolysis intensity of the water electrolysis device meets the set conditions. The determination has high accuracy and low cost.

[0097] The current density at the anode 2 and / or cathode 3 can be detected by a current density sensor. The current density of the anode 2 alone can be detected; the current density of the cathode 3 alone can be detected; or both the current density of the anode 2 and the current density of the cathode 3 can be detected. Whether the electrolysis intensity of the water electrolysis device satisfies a set condition can be determined by determining whether the current density of the anode 2 alone or the current density of the cathode 3 alone is within a set current density range. Whether the electrolysis intensity of the water electrolysis device satisfies a set condition can also be determined by determining whether both the current density of the anode 2 and the current density of the cathode 3 are within a set current density range. Whether the electrolysis intensity of the water electrolysis device satisfies a set condition can also be determined by determining whether the average value of the current density of the anode 2 and the current density of the cathode 3 is within a set current density range.

[0098] Of course, other indicators can also be used to determine whether the electrolysis intensity of the water electrolysis device meets the set conditions, such as the output current of the power supply 4, the ozone concentration in the water receiving component 1, etc. These indicators are positively correlated with the electrolysis intensity of the water electrolysis device, and can therefore be used to indicate whether the electrolysis intensity of the water electrolysis device meets the set conditions.

[0099] In some exemplary embodiments, starting the water electrolysis device includes: starting the water electrolysis device according to the initial set voltage. In other words, when the water electrolysis device is started, the output voltage of the power supply 4 is the set initial voltage, such as Figure 6 As shown. Starting the electrolysis device according to the initial voltage is beneficial to saving energy consumption. Of course, the electrolysis device can also be started according to the voltage before the electrolysis device finished working last time.

[0100] In some exemplary embodiments, the control method further includes: based on the electrolysis intensity of the water electrolysis device not meeting the set conditions, controlling the power supply 4 to increase the output voltage (such as Figure 6 As shown), and returns to the step of determining whether the electrolysis intensity of the water electrolysis device meets the set conditions.

[0101] When the ion content in the condensed water is insufficient and the conductivity is low, the electrolytic strength of the water electrolysis device may be relatively low. At this time, it is necessary to increase the output voltage of the power supply 4 to improve the electrolytic strength of the water electrolysis device, so as to achieve sufficient gas precipitation and ensure an effective cleaning effect.

[0102] In some exemplary embodiments, controlling the power supply 4 to increase the output voltage includes: controlling the output voltage of the power supply 4 to increase a set voltage value. The set voltage value may be, but is not limited to, 1V, such as Figure 6 shown.

[0103] Of course, the way of increasing the output voltage is not limited to increasing the set voltage value each time. For example, it can also be increased in a proportional manner (percentage or multiple), or increased in an up-shift manner according to a preset voltage level.

[0104] In some exemplary embodiments, the applied voltage is related to the conductivity of the condensed water. Condensed water has a certain degree of conductivity due to contamination and other factors. The applied voltage is set based on the conductivity of the condensed water, typically within the range of 8-20V. That is, the output voltage of power supply 4 is within the range of 8V to 20V, such as 8V, 10V, 12V, 15V, 18V, 20V, etc.

[0105] In this way, the water receiving device 100 provided in the embodiment of the present application can use a low-voltage DC power supply to drive the electrolysis of condensed water to remove dirt and mildew inside the fuselage, which is safe and effective and will not cause harm to the human body and the fuselage.

[0106] Of course, the output voltage of the power supply 4 is not limited to the above range and can be adjusted as needed.

[0107] In some exemplary embodiments, determining to enter the cleaning mode of the water receiving component 1 includes:

[0108] Entering the self-cleaning mode is determined according to at least one of the operating time of the electrical device, an external instruction, and the degree of dirtiness of the water receiving component 1 .

[0109] For example: based on the second set time of the electrical equipment running, it is determined to enter the self-cleaning mode, such as Figure 6 As shown. This allows the electrical device to automatically self-clean regularly without manual user control, which helps improve the product's intelligence. When the electrolysis device operates for the first time, the second set timer starts counting from the time the electrical device first starts operating. For subsequent operations, the second set timer can start counting from the time the electrolysis device last ended operating. The second set timer should not be too long, as this will result in excessive contaminants that are difficult to clean; nor should it be too short, as this will result in frequent operation of the electrolysis device. The second set timer can be, but is not limited to, two weeks.

[0110] Based on the external command received, the device enters the self-cleaning mode. This allows the appliance to self-clean according to the user's command, helping to meet the user's personalized needs. The external command can be sent via a remote control, control panel, or terminal device (such as a mobile phone or computer).

[0111] If the degree of contamination of the water receiving component 1 reaches a set level, the system enters self-cleaning mode. This reduces the operating frequency of the electrolysis device and helps extend its service life. The degree of contamination of the water receiving component 1 can be determined by photographing, identifying, or comparing the water receiving component 1.

[0112] In some exemplary embodiments, the electrical device further includes a compressor (not shown in the figure) and an evaporation fan 6, which is configured to form an air flow passing through the evaporator 5. Figure 6 As shown, the control method further includes:

[0113] Based on the switch from the first set working mode to the self-cleaning mode, the compressor of the electrical equipment is controlled to operate at a reduced frequency, the evaporation fan 6 of the electrical equipment is controlled to be turned off, and the surface temperature of the evaporator 5 is made higher than 0°C.

[0114] In this way, the surface temperature of the evaporator 5 can be maintained above 0°C, preventing frost on the evaporator 5. In addition, this facilitates the diffusion of gas overflowing from the water receiving component 1 inside the fuselage, and the gaseous sterilization factors are used to prevent and disinfect microbial contaminants in all directions and without dead ends for other parts inside the fuselage.

[0115] The evaporation fan 6 refers to a fan provided corresponding to the evaporator 5 , and is used to generate an airflow passing through the evaporator 5 .

[0116] In some exemplary embodiments, the control method further includes:

[0117] Based on the determination of exiting the self-cleaning mode and entering the second set working mode, the compressor and the evaporating fan 6 of the electrical device are controlled to operate according to the second set working mode.

[0118] The first set working mode and the second set working mode can be the same mode or different modes. In the first set working mode, the compressor needs to run. The first set working mode can be a cooling mode.

[0119] After exiting the self-cleaning mode, the compressor is controlled to resume the required operating frequency and the evaporating fan 6 resumes operation, which can generate additional condensed water to discharge the floating residue in the water receiving component 1.

[0120] An embodiment of the present application also provides a control device, including a processor and a memory storing a computer program. When the processor executes the computer program, it implements the steps of any control method in the above embodiments, thereby having all the above-mentioned beneficial effects, which will not be repeated here.

[0121] The processor may be an integrated circuit chip with signal processing capabilities. The above-mentioned processor may be a general-purpose processor, including a central processing unit (CPU), a network processor (NP), etc.; it may also be a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or other programmable logic device, a discrete gate or transistor logic device, or a discrete hardware component. It can implement or execute the various methods, steps, and logic block diagrams disclosed in the embodiments of the present invention. The general-purpose processor may be a microprocessor or any conventional processor.

[0122] An embodiment of the present application also provides a computer-readable storage medium storing a computer program. When the computer program is executed by a processor, the computer program implements the steps of any control method in the above embodiments, thereby having all the above-mentioned beneficial effects, which will not be repeated here.

[0123] In summary, the water receiving device, electrical equipment, and control method and control device provided in the embodiments of the present application utilize low-voltage direct current (DC) to electrolyze condensed water for internal cleaning and mildew removal. Strong oxidants such as oxygen, ozone, and other reactive oxygen species are released at the interface between the anode and the solution, while the cathode serves as a hydrogen-evolving electrode. The resulting bubbles mechanically remove stubborn stains and bacterial colonies adhering to the surface of the water receiving components, allowing the remaining contaminants to be discharged with the condensed water. The generated gas overflows the water surface and sterilizes and inhibits bacteria in internal components such as the evaporator above. Due to the limited amount of ozone generated, it does not pollute the interior of the device. This method can address bacterial and fungal growth and stubborn dirt formation in the water receiving tray, which is the most susceptible to microbial contamination and is difficult to access and clean from the outside. It targets the area where the dirt is generated, making it widely applicable. For other internal components of the device, gaseous sterilizing agents can be used to prevent and eliminate microbial contamination in all directions without blind spots. Furthermore, this method is driven by low-voltage DC, making it safe and effective, and harmless to the human body and the device itself.

[0130] In any one or more of the above exemplary embodiments, the functions described may be implemented in hardware, software, firmware, or any combination thereof. If implemented in software, the functions may be stored as one or more instructions or codes on or transmitted via a computer-readable medium and executed by a hardware-based processing unit. The computer-readable medium may include a computer-readable storage medium corresponding to a tangible medium such as a data storage medium, or a communication medium that facilitates the transfer of a computer program from one place to another, such as according to a communication protocol. In this manner, a computer-readable medium may generally correspond to a non-transitory tangible computer-readable storage medium or a communication medium such as a signal or carrier wave. The data storage medium may be any available medium that can be accessed by one or more computers or one or more processors to retrieve instructions, codes, and / or data structures for implementing the techniques described in this disclosure. A computer program product may include a computer-readable medium.

[0131] By way of example and not limitation, such computer-readable storage media may include RAM, ROM, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage, flash memory, or any other medium that can be used to store desired program code in the form of instructions or data structures and that can be accessed by a computer. Furthermore, any connection may also be referred to as a computer-readable medium. For example, if instructions are transmitted from a website, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwaves, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwaves are included in the definition of medium. However, it should be understood that computer-readable storage media and data storage media do not include connections, carrier waves, signals, or other transient (transient) media, but rather refer to non-transient tangible storage media. As used herein, disk and optical disk include compact disc (CD), laser disc, optical disc, digital versatile disc (DVD), floppy disk, or Blu-ray disc, among others, where disks typically reproduce data magnetically, while optical discs use lasers to reproduce data optically. Combinations of the above should also be included within the scope of computer-readable media.

[0132] For example, instructions may be executed by one or more processors, such as one or more digital signal processors (DSPs), general-purpose microprocessors, application-specific integrated circuits (ASICs), field-programmable logic arrays (FPGAs), or other equivalent integrated or discrete logic circuits. Thus, the term "processor," as used herein, may refer to any of the aforementioned structures or any other structure suitable for implementing the techniques described herein. Additionally, in some aspects, the functionality described herein may be provided within dedicated hardware and / or software modules configured for encoding and decoding, or incorporated into a combined codec. Furthermore, the techniques may be fully implemented in one or more circuits or logic elements.

[0133] The technical solutions of the embodiments of the present disclosure can be implemented in a wide variety of devices or equipment, including wireless mobile phones, integrated circuits (ICs), or a group of ICs (e.g., chipsets). Various components, modules, or units are described in the embodiments of the present disclosure to emphasize the functional aspects of the devices configured to perform the described techniques, but they do not necessarily need to be implemented by different hardware units. Instead, as described above, the various units can be combined in a codec hardware unit or provided by a collection of interoperable hardware units (including one or more processors as described above) in combination with appropriate software and / or firmware.
