Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a sterilization control method, device, system, air conditioner and storage medium. Background Art

[0002] The interior of some household appliances is prone to dust and moisture accumulation, thus providing an ideal growth environment for microorganisms such as bacteria, viruses, and mold. The growth of microorganisms will produce odors and affect the indoor air quality; long-term exposure to polluted air may cause health problems such as respiratory diseases and allergic reactions. For example, the air ducts, filters and other components in air conditioners, air purifiers, humidifiers and other systems are located inside and are not easy to clean. Ultraviolet sterilization and other means are needed to kill the microorganisms in them.

[0003] In equipment such as air conditioners and refrigerators, some parts are prone to water film, which increases the internal humidity and is easy to breed microorganisms. Traditional ultraviolet sterilization methods usually have fixed parameters and cannot be adjusted according to actual environmental changes, resulting in unsatisfactory sterilization effects or waste of resources. For example, timed turning on a fixed-power ultraviolet sterilization lamp, regularly releasing a fixed amount of sterilizer, etc. In fact, changes in the thickness of the water film will greatly affect the speed and number of bacterial growth. In a high-humidity environment, the evaporator water film is thicker, microorganisms reproduce rapidly, and a fixed-intensity sterilization method is difficult to completely remove bacteria; while in a low-humidity environment, the water film is thinner, and excessive sterilization operations not only waste energy, but may also accelerate equipment aging.

Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0039] In order to solve the technical problems of inflexible operation, high power consumption and poor sterilization effect of the prior art sterilization equipment, the present application provides a sterilization control method that can adjust the sterilization intensity according to the water film thickness in real time, thereby achieving better sterilization effect and lower power consumption of the sterilization equipment.

[0040] Figure 1 A flow chart of a sterilization control method provided in an embodiment of the present application. This method can be applied to devices such as air conditioners, refrigerators, air purifiers, humidifiers, etc., and executed by electronic devices such as controllers and processors in these devices, or by other electronic devices connected to these devices. In addition, the execution subject of this method can be hardware or software. When the above-mentioned execution subject is hardware, the execution subject can be one or more of the above-mentioned electronic devices. For example, a single electronic device can execute this method, or multiple electronic devices can cooperate with each other to execute this method. When the above-mentioned execution subject is software, this method can be implemented as multiple software or software modules, or as a single software or software module. It is not specifically limited here.

[0041] like Figure 1 As shown, the method specifically includes:

[0042] Step 101, obtaining a sensing signal collected by a water film thickness sensing device.

[0043] In some embodiments, the water film thickness sensing device is used to sense the water film thickness on the surface of the detected device. As an example, the water film thickness sensing device can be an ultrasonic thickness measuring device, an optical thickness measuring device, etc. The water film thickness sensing device can sense the water film thickness on the surface of the detected device without contact, and the obtained sensing signal can reflect the water film thickness.

[0044] The above-mentioned detected equipment can be various equipment that is prone to produce water film, such as the evaporator in the air conditioner.

[0045] Step 102: Determine the thickness of the water film on the surface of the detected device based on the sensing signal.

[0046] In some embodiments, the sensing signal can reflect the thickness of the water film, and the water film thickness can be obtained by processing and calculating the sensing signal. For example, the water film thickness sensing device can be an optical film thickness gauge, which uses the principle that light interferes after being reflected by two surfaces of the water film to sense the interference phenomenon, and the obtained sensing signal can be an interference fringe image. Then, based on the corresponding relationship between the interference fringes and the film thickness, the water film thickness is calculated.

[0047] Step 103, based on the preset correspondence between the water film thickness and the sterilization intensity, determine the sterilization intensity corresponding to the water film thickness.

[0048] In some embodiments, the correspondence between the water film thickness and the sterilization intensity can be preset, and the correspondence can be expressed in a table, a calculation formula, etc. The sterilization intensity can be expressed in a level or a specific value, etc. Generally, the thicker the water film is, the easier it is to breed bacteria and other microorganisms, and the greater the sterilization intensity required; the thinner the water film is, the less likely it is to breed bacteria, and the smaller the sterilization intensity required.

[0049] Step 104: Based on the sterilization intensity, adjust the working parameters of the sterilization equipment so that the sterilization equipment performs the sterilization operation according to the sterilization intensity.

[0050] In some embodiments, the sterilization equipment may be various types of equipment, such as equipment utilizing ultraviolet sterilization, equipment utilizing high temperature sterilization, equipment spraying sterilizers, and the like.

[0051] Different sterilization intensities correspond to different working parameters. For example, different operating powers of sterilization equipment correspond to different sterilization intensities, and thus to different working parameters. That is, the working parameters representing the operating power are adjusted so that the sterilization equipment performs the sterilization operation according to the corresponding power.

[0052] The sterilization control method provided in the embodiment of the present application senses the thickness of the water film on the surface of the detected device, determines the thickness of the water film on the surface of the detected device based on the sensing signal, and then determines the sterilization intensity corresponding to the water film thickness. Finally, based on the sterilization intensity, the working parameters of the sterilization device are adjusted so that the sterilization device performs the sterilization operation according to the sterilization intensity. The embodiment of the present application realizes real-time detection of the water film thickness and real-time adjustment of the sterilization intensity according to the water film thickness, thereby performing the sterilization operation more specifically, improving the sterilization effect, and avoiding the sterilization device from sterilizing at a fixed power, thereby reducing the power consumption of the sterilization device.

[0053] In some optional implementations, the sensing signal is an ultrasonic sensing signal, that is, the water film thickness sensing device is an ultrasonic device, which can emit ultrasonic waves and receive reflected ultrasonic waves.

[0054] like Figure 2 As shown, step 102 includes:

[0055] Step 1021: Determine the time from transmitting the ultrasonic wave to receiving the ultrasonic wave reflected by the surface of the detected device based on the ultrasonic sensing signal.

[0056] The ultrasonic device may include an ultrasonic transmitting unit and an ultrasonic receiving unit. The ultrasonic transmitting unit may transmit ultrasonic waves to the surface of the detected device, and the ultrasonic waves are reflected. The ultrasonic receiving unit receives the reflected ultrasonic waves and converts them into electrical signals, which are ultrasonic sensing signals.

[0057] By recording the time when the ultrasonic wave transmitting unit transmits the ultrasonic wave and the time when the ultrasonic wave receiving unit receives the reflected ultrasonic wave, the time elapsed from transmitting the ultrasonic wave to receiving the reflected ultrasonic wave can be determined.

[0058] Step 1022, determining the thickness of the water film on the surface of the detected device according to the duration and the propagation speed of the ultrasonic wave.

[0059] Since there is air between the ultrasonic device and the device to be detected, and the propagation speed of ultrasonic waves in the air is a known quantity, it is possible to detect the time elapsed from the emission of ultrasonic waves to the reception of ultrasonic waves reflected from the surface of the device to be detected in advance without a water film, and use this time as the initial time, and subtract it from the time detected in step 1021 to obtain the time difference. Based on this time difference and the propagation speed of ultrasonic waves, the thickness of the water film can be calculated. The specific calculation formula is shown in the following formula (1):

[0060] h = (v × Δt) / 2 (1)

[0061] Where h represents the thickness of the water film, v represents the propagation speed of ultrasound in the air, and Δt is the time difference between ultrasound transmission in the presence and absence of water film.

[0062] This embodiment adopts ultrasonic method to calculate the water film thickness on the surface of the detected device by detecting the transmission time of ultrasonic wave, thereby realizing real-time and accurate detection of water film thickness. In addition, ultrasonic equipment has low cost and is easy to install, which helps to improve the efficiency of water film thickness detection.

[0063] In some optional implementations, such as Figure 3 As shown, step 104 includes:

[0064] Step 1041, determining the preset operating power and / or operating time corresponding to the sterilization intensity.

[0065] Specifically, different sterilization intensities may correspond to different operating powers and / or operating durations. That is, the operating powers corresponding to different sterilization intensities may be set separately, and after the sterilization intensity is determined, the corresponding operating powers may be determined; the operating durations corresponding to different sterilization intensities may be set separately, and after the sterilization intensity is determined, the operating duration of the sterilization equipment for this operation may be determined; the operating powers and operating durations corresponding to different sterilization intensities may also be set, and after the sterilization intensity is determined, the operating duration of the sterilization equipment for this operation and the operating power for this operation may be determined.

[0066] Step 1042: Adjust the working parameters of the sterilization equipment based on the operating power and / or operating time, so that the sterilization equipment performs the sterilization operation according to the sterilization intensity.

[0067] That is, the parameters for controlling the operating power and / or operating time included in the working parameters are adjusted, and the operation of the sterilization equipment is controlled according to the adjusted parameters. It should be noted that, when the sterilization intensity only has the corresponding operating power, a default operating time (e.g., a fixed 3 minutes) can be set. When the sterilization intensity only has the corresponding operating time, a default operating power (e.g., 80% of the maximum power of the sterilization equipment) can be set.

[0068] By setting the operating power and / or operating time corresponding to different sterilization intensities, this embodiment can more accurately control the sterilization equipment to perform sterilization operations of different degrees based on the water film thickness, thereby helping to sterilize more effectively and flexibly.

[0069] In some optional implementations, such as Figure 4 As shown, step 103 includes:

[0070] Step 1031 : determining a target water film thickness interval to which the water film thickness belongs from at least two preset water film thickness intervals.

[0071] As an example, the water film thickness intervals include three intervals: less than or equal to 0.2 mm, greater than 0.2 mm and less than or equal to 0.5 mm, and greater than 0.5 mm.

[0072] Step 1032: Determine the target sterilization intensity level corresponding to the target water film thickness interval based on the preset correspondence between the water film thickness interval and the sterilization intensity level.

[0073] The water film thickness interval and the sterilization intensity level can correspond one to one. For example, the above three water film thickness intervals correspond to low, medium and high sterilization intensity levels respectively. If the target water film thickness interval is greater than 0.5 mm, the corresponding target sterilization intensity level is a high sterilization intensity level.

[0074] like Figure 4 As shown, step 104 includes:

[0075] Step 1043, determining whether the detected device currently meets the sterilization conditions.

[0076] Among them, the sterilization conditions can be set according to actual needs. Optionally, it can be combined with the current temperature of the detected device to determine whether the sterilization conditions are met. For example, at any sterilization intensity, when the temperature is less than the preset temperature threshold, bacteria are likely to grow, and it is determined that the sterilization conditions are met.

[0077] Step 1044, if the sterilization conditions are met, based on the pre-set correspondence between the sterilization intensity level and the working parameters, adjust the working parameters of the sterilization equipment to the working parameters corresponding to the target sterilization intensity level.

[0078] Among them, different sterilization intensity levels correspond to different working parameters. After the target sterilization intensity level is determined, the sterilization operation can be performed according to the corresponding working parameters.

[0079] Optionally, this embodiment can be combined with the above Figure 3 In combination with the corresponding embodiment, different sterilization intensity levels correspond to different operating powers and / or operating durations. After the target sterilization intensity level is determined, the sterilization operation can be performed according to the corresponding operating power and / or operating duration.

[0080] For example, if the detected water film thickness is less than or equal to 0.2 mm, the target sterilization intensity level is determined to be a low level, the corresponding operating power is 30% to 50% of the rated power of the sterilization equipment, and the operating time is 5 to 8 minutes;

[0081] If the detected water film thickness is greater than 0.2mm and less than or equal to 0.5mm, the target sterilization intensity level is determined to be medium, the corresponding operating power is 50% to 80% of the rated power of the sterilization equipment, and the operating time is 8 to 10 minutes;

[0082] If the detected water film thickness is greater than 0.5 mm, the target sterilization intensity level is determined to be a high level, the corresponding operating power is 80% to 100% of the rated power of the sterilization equipment, and the operating time is 10 to 15 minutes.

[0083] This embodiment sets multiple sterilization intensity levels and controls the sterilization equipment to operate according to the corresponding sterilization intensity level according to the water film thickness, thereby making the operation of adjusting the working parameters of the sterilization equipment more concise and helping to improve the sterilization efficiency.

[0084] In some optional implementations, such as Figure 5 As shown, step 1043 includes:

[0085] Step 10431: If the target sterilization intensity level is the first sterilization intensity level, determine the temperature of the detected device.

[0086] The first sterilization intensity level can be set according to actual needs. Usually, the first sterilization intensity level is the lowest intensity level. The temperature of the detected device can be sensed by a temperature sensor set on the detected device.

[0087] Step 10432: If the temperature is less than the preset temperature threshold, it is determined that the detected device currently meets the sterilization conditions.

[0088] As an example, if the method is applied to an air conditioner, the detected device may be an evaporator included in the air conditioner, and the temperature of the detected device may be the inner tube temperature. The first sterilization intensity level is the lowest intensity level, that is, when the water film thickness is in the minimum interval (for example, the above interval less than or equal to 0.2 mm), if the temperature is less than the preset temperature threshold (for example, 80°C), it is determined that the detected device currently meets the sterilization conditions, and then the sterilization device is controlled to perform the sterilization operation according to the corresponding working parameters. If the above temperature is greater than or equal to the preset temperature threshold, the higher inner tube temperature has a certain sterilization effect, and sterilization is not required at this time, that is, it is determined that the detected device currently does not meet the sterilization conditions.

[0089] This embodiment determines whether a sterilization operation needs to be performed based on the temperature when the water film thickness corresponds to the first sterilization intensity level, and makes full use of the influence of ambient temperature on microorganisms for sterilization, thereby avoiding energy consumption and equipment damage caused by still starting sterilization in a high-temperature environment, which helps to extend the life of the equipment.

[0090] In some optional implementations, such as Figure 5 As shown, step 1043 includes:

[0091] Step 10433: If the target sterilization intensity level is not the first sterilization intensity level, determine whether the detected device currently meets the sterilization conditions.

[0092] As an example, if the first sterilization intensity level is the lowest intensity level, and the corresponding water film thickness is in the minimum water film thickness range (for example, the above-mentioned range less than or equal to 0.2 mm), then when the target sterilization intensity level is not the first sterilization intensity level, that is, the water film thickness is greater than 0.2 mm, the temperature value is not referred to, and it is directly judged that the sterilization conditions are met, and the sterilization operation is performed immediately.

[0093] Since the detected equipment is more likely to breed bacteria and other microorganisms when the target sterilization intensity level is not the first sterilization intensity level, performing the sterilization operation immediately at this time will help to further improve the sterilization effect and improve the sterilization efficiency.
