In the following, the self-cleaning method of the air conditioner provided in the embodiments of the present application is described, wherein the electronic device is used as an executing body in the embodiments of the present application, and the executing body is omitted in the following embodiments of the method for simplifying and facilitating the description.
Referring to fig. 2, fig. 2 is a schematic flow chart of a self-cleaning method of an air conditioner according to an embodiment of the present disclosure. It should be noted that, although a logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different than that shown or described herein. The self-cleaning method of the air conditioner comprises the steps 201 to 202, wherein:
201. sterilizing the evaporator by the photocatalyst;
the photocatalyst is a photo-semiconductor material with a photocatalytic function represented by nano-scale titanium dioxide, can generate a photocatalytic reaction similar to photosynthesis under the irradiation of ultraviolet rays with the wavelength of below 388nm to generate free hydroxyl and active oxygen with extremely strong oxidizing power, has a very strong photo-oxidation-reduction function, can oxidize and decompose various organic compounds and partial inorganic matters, can destroy cell membranes of bacteria and proteins for curing viruses, can kill the bacteria and decompose organic pollutants, and can decompose the organic pollutants into pollution-free water (H2O) and carbon dioxide (CO 2).
In the embodiment of the application, the killing effect of the photocatalyst on heat-resistant bacteria is considered in a new way, the bacteria on the evaporator are killed through the photocatalyst, and compared with the traditional sterilization method, the method can further kill the microorganisms with high temperature resistance during self-cleaning.
When the evaporator is sterilized, the photocatalyst contained in the photocatalyst reactor can be catalyzed by an ultraviolet irradiation part preset on the air conditioner, the catalyzed photocatalyst is radiated onto the heat exchange fins of the evaporator, and the catalyzed photocatalyst can react with dirt such as bacterial secretion on the heat exchange fins to decompose the dirt.
The ultraviolet irradiation part is a part for radiating ultraviolet rays, and may be an ultraviolet lamp or the like, which is not limited in the embodiment of the present application.
In some embodiments, after receiving a cleaning mode start instruction from a user, the air conditioner may turn on the ultraviolet irradiation unit to catalyze the photocatalyst contained in the photocatalyst reactor and radiate the catalyzed photocatalyst onto the heat exchange fins of the evaporator, where the catalyzed photocatalyst may react with dirt such as bacterial secretion on the heat exchange fins to decompose the dirt.
In other embodiments, the air conditioner may automatically enter the cleaning mode after a certain condition is met, so as to realize the self-cleaning function. In this case, before the step "sterilizing the evaporator with the photocatalyst", the determination may be made in the following manner:
(1) obtaining current operation parameters of the air conditioner, wherein the current operation parameters comprise at least one of accumulated operation time of the air conditioner and compressor load.
The accumulated running time refers to the accumulated running time after the air conditioner is started up until the current running parameters are obtained.
In some embodiments, the accumulated operating time may be determined based on a current wind profile of the air conditioner.
The compressor load refers to a current load of a compressor in the air conditioner.
(2) And if the current operating parameters meet the preset self-cleaning starting conditions, executing the step of sterilizing the evaporator through the photocatalyst.
The three operating parameters are explained below:
(A) when the current operation parameter refers to the accumulated operation time, the self-cleaning starting condition may refer to that the accumulated operation time is greater than or equal to a preset time threshold. For example, a time threshold may be preset to be 2 hours, and when the time of the cumulative operation of the air conditioner after the current startup exceeds 2 hours, it indicates that a large amount of bacteria and dust may have been adsorbed on the evaporator after a long time of operation, so that the ultraviolet irradiation unit may be turned on to catalyze the photocatalyst contained in the photocatalyst reactor and radiate the catalyzed photocatalyst onto the heat exchange fins of the evaporator, and the catalyzed photocatalyst may react with the dirt such as bacterial secretion on the heat exchange fins to decompose the dirt.
In some embodiments, the time threshold may be determined based on a current wind profile of the air conditioner. For example, when the current wind gear is lower than the middle wind gear, the time is setThe threshold is set to T1When the current wind gear is higher than the medium wind gear or the current wind gear is the medium wind gear, the time threshold value is set to be T2Wherein, T1＞T2。
(B) When the current operation parameter refers to a compressor load, the self-cleaning start condition may refer to "the compressor load is less than or equal to a preset load threshold". If the load of the compressor is less than or equal to the preset load threshold value, the heat exchange effect of the evaporator is not good, for example, in a refrigeration mode, if a large amount of bacteria and dust are adsorbed on the evaporator serving as the evaporator, the evaporator is blocked, and the heat replacement and refrigeration effect of the evaporator are affected, because the refrigerant is slowly gasified at the moment and the outdoor side pressure is reduced, the load of the compressor is reduced, the self-cleaning starting condition is met, the ultraviolet irradiation part can be started to catalyze the photocatalyst contained in the photocatalyst reactor and radiate the catalyzed photocatalyst onto the heat exchange fins of the evaporator, and the catalyzed photocatalyst can react with dirt such as bacteria secretion on the heat exchange fins to decompose the dirt.
In addition to the accumulated running time and the compressor load, it is also possible to determine whether the self-cleaning mode needs to be entered by other current operating parameters of the air conditioner. For example, in the cooling mode, the temperature of the inner coil of the air conditioner may be obtained, and if the difference between the temperature of the inner coil and the set temperature is greater than or equal to the preset difference threshold, it indicates that the cooling effect of the current air conditioner is not good, which may be caused by a large amount of bacteria and dust adsorbed on the evaporator, causing the evaporator to be blocked, and affecting the heat exchange and cooling effects of the evaporator, so the ultraviolet irradiation part may be turned on to catalyze the photocatalyst contained in the photocatalyst reactor, and radiate the catalyzed photocatalyst onto the heat exchange fins of the evaporator, and the catalyzed photocatalyst may react with the dirt such as bacteria secretion on the heat exchange fins, so as to decompose the dirt.
202. And after the sterilization is finished, cleaning the sterilized evaporator.
In the embodiment of the application, the sterilized evaporator can be cleaned, and dirt residues decomposed on the heat exchange fins of the evaporator are removed.
In some embodiments, the sterilized evaporator may be washed by water through a preset washing part. For example, the indoor unit may be provided with a component such as an atomizer or a washing pipe, and the evaporator after sterilization may be cleaned by the component.
To sum up, the self-cleaning method of the air conditioner provided by the embodiment of the application comprises the following steps: sterilizing the evaporator by the photocatalyst; and after the sterilization is finished, cleaning the sterilized evaporator. Therefore, the air conditioner self-cleaning method provided by the embodiment of the application sterilizes the evaporator through the photocatalyst, compared with the traditional sterilization method, the heat-resisting bacteria can be well killed, the sterilization effect is better, the operation state of the air conditioner cannot be influenced by mainly relying on the reaction between the photocatalyst and the bacteria in the photocatalyst sterilization mode, and therefore compared with the traditional sterilization method, the air conditioner self-cleaning method provided by the embodiment of the application cannot generate larger fluctuation at room temperature during sterilization, and the comfort of a user can be improved.
In some embodiments, whether sterilization is needed or not can be judged according to the irradiation area of ultraviolet rays on the photocatalyst, and a user does not need to send a cleaning instruction manually, so that the intelligence of the air conditioner can be improved. Referring to fig. 3, at this time, the step of "sterilizing the evaporator by the photocatalyst" includes:
301. and controlling the ultraviolet irradiation component to irradiate the photocatalyst.
302. Detecting a first target irradiation area of ultraviolet rays on the photocatalyst.
The method for detecting the first target irradiation area is not limited in the embodiments of the present application, and the first target irradiation area of the ultraviolet rays on the photocatalyst may be detected by a component such as an illumination detector.
303. If the first target irradiation area is smaller than or equal to a preset first area threshold value, the irradiation of the ultraviolet irradiation component on the photocatalyst is kept, and the evaporator is sterilized through the photocatalyst catalyzed by ultraviolet rays.
The first area threshold is a preset value for evaluating the amount of light rays that the ultraviolet rays can pass through the heat exchange fins.
When the first target irradiation area is smaller than or equal to the preset first area threshold, the situation that dirt deposited on the heat exchange fins of the evaporator is too much and an ultraviolet light path is blocked is shown, so that irradiation of the ultraviolet irradiation component on the photocatalyst can be kept, and the evaporator of the air conditioner is sterilized through the photocatalyst catalyzed by ultraviolet rays. When the first target irradiation area is larger than the preset first area threshold value, the dirt deposited on the heat exchange fins of the evaporator is less, so that the ultraviolet irradiation part can be turned off.
Therefore, the self-cleaning method of the air conditioner provided by the embodiment of the application can realize 2 purposes of sterilization and judgment of sterilization opportunity only by using the photocatalyst and the ultraviolet irradiation part.
The first area threshold value can be obtained by counting ultraviolet irradiation areas on a plurality of photocatalysts after the computer is started. In this case, before the step of "controlling the ultraviolet irradiation means to irradiate the photocatalyst", the first area threshold may be obtained by:
(1) and detecting the reference irradiation area on the photocatalyst after the photocatalyst is irradiated by the ultraviolet irradiation component at a plurality of time points within a preset time period after the air conditioner is started.
The preset time period can be set according to actual conditions. For example, a plurality of time points may be randomly selected within 10 seconds after the air conditioner is turned on, a predetermined ultraviolet irradiation unit may be turned on, and an irradiation area of ultraviolet rays on the photocatalyst, that is, a reference irradiation area may be detected. Alternatively, when the air conditioner is turned on, the ultraviolet irradiation unit may be turned on for 10 seconds, and the irradiation area of the ultraviolet rays on the photocatalyst may be detected at a plurality of time points at random to obtain a plurality of reference irradiation areas.
(2) Setting the average value of each reference irradiation area as a preset first area threshold value.
When the air conditioner is started, dirt is not considered to be adsorbed on the surface of the radiating fin of the evaporator, so that the reference irradiation area can be considered to be the irradiation area of ultraviolet rays on the photocatalyst when dirt is not deposited on the radiating fin, namely the irradiation area when the light path of the ultraviolet rays is not blocked by the dirt. The average value of the multiple reference irradiation areas is used as the first area threshold value, so that the accuracy of the first area threshold value can be improved, and the condition that the first area threshold value is inaccurate due to the fact that the illumination detector is inaccurate when a single reference irradiation area is used as the first area threshold value is avoided.
The method (1) - (2) for setting the first area threshold can adaptively adjust the first area threshold according to different states of the air conditioner when the air conditioner is started, and the method (1) - (2) for setting the first area threshold can be applied to various types of air conditioners without carrying out factory tests on each type of air conditioner and setting different first area thresholds.
In some embodiments, after the current operation parameter of the air conditioner satisfies the preset self-cleaning start condition, step 301 to step 303 may be executed, that is, when it is determined that the current operation parameter of the air conditioner satisfies the preset self-cleaning start condition, the ultraviolet irradiation unit is turned on, the ultraviolet irradiation unit is controlled to irradiate the photocatalyst reactor containing the photocatalyst, if the first target irradiation area of the ultraviolet light on the photocatalyst is less than or equal to the preset first area threshold, irradiation of the photocatalyst by the ultraviolet irradiation unit is maintained, and the evaporator of the air conditioner is sterilized by the photocatalyst catalyzed by the ultraviolet light.
In some embodiments, besides water washing, the sterilized evaporator can be washed by frost washing, and frost washing has the advantage of no need of additional washing parts compared with water washing, thereby reducing the cost of the air conditioner. At this time, the step "if the first target irradiation area is smaller than or equal to a preset first area threshold, the irradiation of the photocatalyst by the ultraviolet irradiation part is maintained, and the evaporator is sterilized by the photocatalyst catalyzed by ultraviolet rays" may be implemented as follows:
(1) and if the first target irradiation area is smaller than or equal to a preset first area threshold value, acquiring the operation mode of the air conditioner.
(2.1) if the operation mode is a refrigeration mode, closing an internal fan of the air conditioner, keeping the ultraviolet irradiation component irradiating the photocatalyst, and sterilizing the evaporator through the photocatalyst catalyzed by ultraviolet rays.
(2.2) if the operation mode is a heating mode, controlling the air conditioner to enter a cooling mode, closing an inner fan of the air conditioner, keeping the ultraviolet irradiation component irradiating the photocatalyst, and sterilizing the evaporator through the photocatalyst catalyzed by ultraviolet rays.
The method comprises the following steps of after sterilization is finished, cleaning the sterilized evaporator, and comprises the following steps:
(3) after sterilization is finished, the inner fan is started and/or the air conditioner is controlled to enter a heating mode, so that the evaporator is defrosted and cleaned.
When the air conditioner detects that the first target irradiation area is smaller than or equal to a preset first area threshold value, if the air conditioner is in a refrigeration mode at present, the inner fan is closed, and if the air conditioner is in a heating mode at present, the mode is adjusted to the refrigeration mode, and meanwhile, the inner fan is closed.
The reason why the air conditioner is controlled to enter the refrigeration mode and the inner fan is closed is that the evaporator cannot exchange heat with the outside, air around the evaporator is liquefied when being cooled and generates condensed water on the outer surface of the evaporator, and then the condensed water is frosted, so that on one hand, undecomposed dirt in the evaporator can be wrapped in the frosted dirt, and on the other hand, decomposed dirt residues can be washed in the subsequent defrosting process to clean the sterilized evaporator.
After sterilization is finished, the internal fan can be started; (II) controlling the air conditioner to enter a heating mode; in order to clean the sterilized evaporator. It can be understood that if the evaporator is defrosted through the second step, the defrosting efficiency is high, the user waiting time is short, but the energy consumption is large. If the evaporator is defrosted through the first defrosting mode, defrosting efficiency is low, waiting time of a user is long, and energy consumption is saved. Therefore, the defrosting method can be selected according to actual requirements. For example, when the air conditioner is started, the user can select one of 'quick cleaning' or 'ordinary cleaning', and if the user selects 'quick cleaning', when the air conditioner enters a cleaning mode, (two) defrosting the evaporator is adopted; if the user selects "normal cleaning," then when the air conditioner enters the cleaning mode, the evaporator is defrosted using (one). After a period of time after defrosting has begun, the air conditioner may automatically adjust the mode to the initial mode, and the entire self-cleaning process has been completed.
In the embodiment of the application, the air conditioner can judge that the sterilization is finished when receiving a cleaning mode ending instruction sent by a user, and the sterilized evaporator is cleaned. For example, when the air conditioner receives a cleaning mode end command from a user, the ultraviolet irradiation unit may be turned off, and the atomizer, the washing pipe, and other components in the indoor unit may be turned on to clean the sterilized evaporator.
In some embodiments, the air conditioner can judge whether the sterilization is completed according to the irradiation area of the ultraviolet rays on the photocatalyst, so as to realize the function of automatic cleaning. First, describing the structure of the air conditioner in this case, referring to fig. 4, fig. 4 is a structure of the air conditioner, and the air conditioner 400 in fig. 4 includes an evaporator 401, an ultraviolet irradiation part 402, and a photocatalyst reactor 403 for holding a photocatalyst, and the ultraviolet irradiation part 402 and the photocatalyst reactor 403 may or may not be connected to the evaporator 401. The evaporator 401 is composed of a plurality of heat exchanging fins 4011, and the ultraviolet irradiation part 402 and the photocatalyst reactor 403 are respectively disposed on both sides of the heat exchanging fins on the evaporator 401, wherein the dotted arrows in fig. 4 indicate the radiation direction of ultraviolet rays. As shown in fig. 4. Therefore, when a large amount of dirt is deposited on the heat exchange fins, the ultraviolet rays radiated from the ultraviolet ray radiation part 402 to the photocatalyst reactor 403 will be blocked by the dirt between the heat exchange fins, and the area of the ultraviolet rays radiated on the photocatalyst of the photocatalyst reactor 403 will be smaller than the area of the ultraviolet rays radiated when no dirt is deposited on the heat exchange fins, so that it can be seen that, in the air conditioner 400 in fig. 4, whether the sterilization is completed or not can be judged by the radiation area of the ultraviolet rays on the photocatalyst.
At this time, the step "after the sterilization is completed, cleaning the sterilized evaporator" may be implemented by:
(1) detecting a second target irradiation area of ultraviolet light on the photocatalyst, wherein the ultraviolet light is used to catalyze the photocatalyst.
The irradiation area is an irradiation area of ultraviolet rays on the photocatalyst.
The method for detecting the irradiation area of the second target is not limited in the embodiment of the present application. For example, the second target irradiation area of the ultraviolet ray on the photocatalyst may be detected by a light irradiation detector or the like.
(2) And when the second target irradiation area is larger than a preset second area threshold, judging that the sterilization is finished, and cleaning the sterilized evaporator.
The second area threshold is a preset value for evaluating the amount of light that the ultraviolet rays can pass through the heat exchange fins. For example, the irradiation area of ultraviolet rays on the photocatalyst immediately after the heat exchange fin is cleaned may be set as the second area threshold in a factory test.
The second area threshold may be the same as or different from the first area threshold. When the second area threshold is different from the first area threshold, the second area threshold is a value greater than the first area threshold.
If the second target irradiation area is larger than the preset second area threshold value, the number of rays of the ultraviolet rays which can pass through the heat exchange fins is enough, and the number of dirt deposited on the heat exchange fins is small, so that the completion of sterilization can be judged.
Therefore, the purposes that the air conditioner automatically cleans the evaporator can be achieved through the sterilization completion judging methods (1) and (2), a user does not need to send a cleaning mode ending instruction in person, and the intelligence of the air conditioner is improved.
In some embodiments, even if the first target irradiation area is larger than the first area threshold, there may be less dirt deposited on the optical path of the ultraviolet rays, or because the illumination detector does not detect accurately, in order to improve the determination accuracy of the self-cleaning method of the air conditioner, it may be determined whether dirt is deposited on the evaporator according to the temperature of the component of the evaporator when the first target irradiation area is larger than the first area threshold. Referring to fig. 5, at this time, after the step of "detecting the first target irradiation area of the ultraviolet rays on the photocatalyst", the method further includes:
501. and if the first target irradiation area is larger than the first area threshold value, detecting the component temperature of the evaporator through a preset temperature detection component.
The component temperature refers to the temperature of the evaporator, for example, the component temperature may refer to the temperature of heat exchange fins on the evaporator, the temperature of the outer surface of the evaporator, and the like. The temperature detecting member may be provided at various positions on the outer surface of the evaporator, the inner surface of the evaporator, etc., as long as the temperature of the components of the evaporator can be detected.
502. If the temperature of the component is smaller than or equal to a preset temperature threshold value, the ultraviolet irradiation component is used for keeping irradiation on the photocatalyst, and the evaporator is sterilized through the photocatalyst catalyzed by ultraviolet rays.
The temperature threshold is a preset value for evaluating the temperature magnitude of the component. For example, the average component temperature in the absence of fouling on the evaporator may be used as the temperature threshold.
If the temperature of the component is less than or equal to the preset temperature threshold value, the heat exchange efficiency of the evaporator is reduced, and the reason can be inferred to be that dirt is deposited on the evaporator, at the moment, the ultraviolet irradiation component can be kept irradiating the photocatalyst, and the evaporator of the air conditioner is sterilized through the photocatalyst catalyzed by ultraviolet rays.
The following describes an exemplary scenario of a self-cleaning method for an air conditioner:
(1) when the air conditioner is started, the ultraviolet irradiation part is started for 10 seconds, the reference irradiation area on the photocatalyst after the photocatalyst is irradiated by the ultraviolet irradiation part is randomly detected at 3 time points, and the ultraviolet irradiation part is closed after 10 seconds so as to save energy;
(2) calculating the mean value of the 3 reference irradiation areas, and setting the mean value as a first area threshold value;
(3) acquiring a current wind shield of the air conditioner, and determining a time threshold corresponding to the current wind shield according to the current wind shield, wherein the time threshold is assumed to be 2 hours;
(4) starting the ultraviolet irradiation part again when the accumulated running time of the air conditioner during the starting up reaches 2 hours, and detecting a first target irradiation area of ultraviolet rays on the photocatalyst through an illumination detector arranged on the air conditioner;
(5) if the first target irradiation area is smaller than or equal to a preset first area threshold value and the air conditioner is in a refrigeration mode, an inner fan of the air conditioner is turned off; if the first target irradiation area is smaller than or equal to a preset first area threshold value and the air conditioner is in a heating mode, adjusting the mode to a refrigerating mode, and turning off an inner fan of the air conditioner to enable an evaporator to frost;
(6) keeping the irradiation of the photocatalyst by the ultraviolet irradiation part at the same time of the step (5), and sterilizing the evaporator of the air conditioner by the photocatalyst catalyzed by ultraviolet rays;
(7) in the sterilization process, continuously detecting the second target irradiation area of ultraviolet rays on the photocatalyst until the second target irradiation area is larger than a preset second area threshold value, judging that the sterilization is finished, starting an inner fan and/or controlling an air conditioner to enter a heating mode so as to defrost an evaporator and clean the evaporator;
(8) after 10 minutes from the start of defrosting, the mode of the air conditioner is adjusted to the initial mode, for example, when the air conditioner is in the cooling mode before self-cleaning, the mode is adjusted to the cooling mode, and when the air conditioner is in the heating mode before self-cleaning, the mode is adjusted to the heating mode.
