Detailed Description
The embodiment firstly provides the air conditioner, and the frost-condensation animation and the frost-melting animation can be displayed in real time through the operation interface of the mobile terminal bound with the air conditioner, so that a user can visually know the cleaning process of the evaporator, and the use experience of the user is improved. Fig. 1 is a schematic diagram of a binding of an air conditioner 200 with a mobile terminal 300 according to an embodiment of the present invention, and fig. 2 is a schematic block diagram of the air conditioner 200 according to an embodiment of the present invention.
As shown in fig. 1, the air conditioner 200 and the mobile terminal 300 may be bound to receive information through the mobile terminal 300, for example, a self-cleaning command input by a user through an operation interface of the mobile terminal 300. Specifically, the air conditioner 200 and the mobile terminal 300 may be bound by wireless communication means such as Wi-Fi, bluetooth, and the like. The mobile terminal 300 may be an intelligent mobile device such as a smart phone and a tablet computer. As shown in fig. 2, the air conditioner 200 includes a control device 100, the control device 100 includes a processor 110 and a memory 120, wherein the memory 120 stores a control program 121, and the control program 121 is executed by the processor 110 to implement a self-cleaning method of an evaporator in an air conditioner according to any one of the following embodiments.
Fig. 3 is a schematic view illustrating a self-cleaning method of an evaporator in an air conditioner according to an embodiment of the present invention. As shown in fig. 3, the self-cleaning method of the evaporator in the air conditioner may perform the following steps:
step S302, receiving a self-cleaning instruction through an operation interface of the mobile terminal 300 bound with the air conditioner 200;
step S304, controlling the air conditioner 200 to operate in a frost condensation mode according to the self-cleaning instruction, and displaying a frost condensation animation through an operation interface;
step S306, determining whether the time that the air conditioner 200 operates in the frost condensation mode is greater than or equal to a first time threshold, if so, executing step S308, otherwise, returning to execute step S304;
in step S308, the air conditioner 200 is controlled to operate in the defrosting mode, and the defrosting animation is displayed through the operation interface.
In the above steps, the self-cleaning instruction is received through the operation interface of the mobile terminal 300 bound with the air conditioner 200 in step S302. Specifically, the user may input a self-cleaning instruction through the operation interface of the mobile terminal 300, where the self-cleaning instruction is used to implement self-cleaning of the evaporator 210 by defrosting after frost condensation.
In step S304, the air conditioner 200 is controlled to operate in the frost condensing mode according to the self-cleaning command, and specifically, the step of controlling the air conditioner 200 to operate in the frost condensing mode may include: the operation power of the compressor of the air conditioner 200 is controlled to be increased and the air guide plate is closed. In addition, in the frost mode, the fan of the indoor unit of the air conditioner 200 may be controlled to be turned off. Fig. 4 is a schematic view of a frost motion picture in a self-cleaning method of an evaporator in an air conditioner according to an embodiment of the present invention. As shown in fig. 4, the frost animation may include an evaporator 210, frost 220, and dirt 240. Also, the condensation amount of the frost 220 is proportional to a period of time that the air conditioner 200 operates in the frost mode. That is, the longer the time period in which the air conditioner 200 is operated in the frost freezing mode, the greater the amount of condensation of the frost 220 in the frost freezing motion picture. The dirt 240 in the frost motion picture is actually represented by the amount of dust covering the entire surface of the evaporator 210.
In step S306, it is determined whether the time that the air conditioner 200 operates in the frost condensation mode is greater than or equal to the first time threshold, and if yes, step S308 may be executed to control the air conditioner 200 to operate in the defrosting mode. That is, when the time that the air conditioner 200 operates in the frost condensing mode is greater than or equal to the first time threshold, the mode in which the air conditioner 200 operates is controlled to be changed from the frost condensing mode to the defrosting mode. Specifically, the step of controlling the air conditioner 200 to operate in the defrosting mode includes: the compressor is controlled to stop, and the air deflector is opened. In addition, in the defrosting mode, the fan of the indoor unit of the air conditioner 200 may be controlled to operate or continuously maintain the off state.
Fig. 5 is a schematic view of a defrosting animation in a self-cleaning method of an evaporator in an air conditioner according to an embodiment of the present invention. As shown in fig. 5, the defrosting animation may include the evaporator 210, defrosting water 230 formed by heating the frost 220, and dirt 240. Also, the volume of the dirt 240 is inversely proportional to the length of time that the air conditioner 200 is operated in the defrosting mode. That is, the longer the air conditioner 200 operates in the defrosting mode, the smaller the volume of the dirt 240 in the defrosting animation. This is because as the air conditioner 200 is operated in the defrosting mode for a longer period of time, the more defrosting water 230 is formed by melting the frost 220 by heat, the more dust on the surface of the evaporator 210 can be cleaned, and the smaller the volume of the dirt 240, which is the amount of dust on the entire surface of the evaporator 210, becomes. Further, as shown in fig. 4 and 5, the dirt 240 in the frost moving picture and the defrosting moving picture may be differently set in position in addition to the volume change. The dirt 240 in the defrosting animation is located further down than the dirt 240 in the frosting animation, which may vividly indicate the process of the defrosting water 230 washing the dirt 240, so that the dirt 240 leaves the surface of the evaporator 210.
It should be noted that, during the operation of the air conditioner 200 in the frost formation mode and the defrosting mode, the temperature of the coil of the air conditioner 200 is changed all the time, so that the surface of the evaporator 210 can be subjected to frost formation and defrosting. Specifically, the temperature of the coil pipe is gradually reduced to 0 ℃, then continuously reduced for a period of time and continuously increased, and finally increased to above 0 ℃. After the air conditioner 200 is operated in the frost mode, the coil temperature gradually drops, but before not dropping to 0 ℃, the evaporator 210 surface does not actually begin to frost. After the coil temperature drops to 0 ℃, frost begins to form on the surface of the evaporator 210. After the air conditioner 200 is operated in the defrosting mode, the temperature of the coil gradually increases, but before the temperature of the coil does not increase to 0 ℃, the surface of the evaporator 210 does not actually start defrosting, and when the temperature of the coil increases to above 0 ℃, the defrosting is stopped and started.
In a preferred embodiment, after the step of displaying the defrosting animation through the operation interface at step S308, the method may further include: judging whether the time that the air conditioner 200 operates in the defrosting mode is greater than or equal to a second time threshold; and if so, determining that the self-cleaning process is finished. The second time threshold is K/Tw-TbWherein, TwK is a predetermined defrosting coefficient, T, is an ambient temperature of an environment in which the air conditioner 200 is locatedbIs a preset compensation value. The air conditioner 200 is respectively operated in the defrosting mode and the defrosting mode according to the preset first time threshold and the preset second time threshold, so that the surface of the evaporator 210 can be smoothly defrosted and defrosted, and dust on the surface of the evaporator 210 can be cleaned. In addition, the defrosting water 230 after cleaning the dust may be directly discharged through a drain pipe of the air conditioner 200, thereby preventing pollution of the internal environment of the air conditioner 200.
In the self-cleaning method for the evaporator in the air conditioner, the self-cleaning instruction is received through the operation interface of the mobile terminal 300 bound with the air conditioner 200, the air conditioner 200 is controlled to operate in the frost condensation mode according to the self-cleaning instruction, the frost condensation animation is displayed through the operation interface, whether the time for the air conditioner 200 to operate in the frost condensation mode is greater than or equal to a first time threshold value or not is judged, and when the result is yes, the air conditioner 200 is controlled to operate in the defrosting mode, and the frost condensation animation is displayed through the operation interface. The frost-condensation animation and the frost-melting animation are displayed in real time through the operation interface, so that a user can visually know the cleaning process of the evaporator 210, and the use experience of the user is improved.
In some optional embodiments, the air conditioner 200 may achieve a higher technical effect by further optimizing and configuring the above steps, and the following describes the self-cleaning method for the evaporator in the air conditioner of this embodiment in detail with reference to an optional execution flow of this embodiment, where this embodiment is merely an illustration of the execution flow, and in a specific implementation, the execution sequence and the operation conditions of some steps may be modified according to specific implementation requirements. Fig. 6 is a detailed flowchart of a self-cleaning method of an evaporator in an air conditioner according to an embodiment of the present invention, the self-cleaning method of an evaporator in an air conditioner including the steps of:
step S602, receiving a self-cleaning command through an operation interface of the mobile terminal 300 bound with the air conditioner 200;
step S604, detecting the dust coverage on the surface of the evaporator 210;
step S606, determining a corresponding interface color according to the dust coverage rate;
step S608, outputting the dust coverage rate and the interface color through the operation interface;
step S610, controlling the air conditioner 200 to operate in a frost condensation mode according to the self-cleaning instruction, and displaying a frost condensation animation through an operation interface;
step S612, controlling the air conditioner 200 to operate in the frost setting mode, and displaying a frost setting animation through the operation interface;
step S614, determining whether the time that the air conditioner 200 operates in the frost condensation mode is greater than or equal to the first time threshold, if so, executing step S616, otherwise, returning to execute step S612;
step S616, controlling the air conditioner 200 to operate in the defrosting mode, and displaying the defrosting animation through the operation interface;
step S618, determining whether the time that the air conditioner 200 operates in the defrosting mode is greater than or equal to the second time threshold, if yes, performing step S620, otherwise, returning to step S616;
step S620, determining the end of the self-cleaning process;
in step S622, the dust coverage is redetected, and the dust coverage after self-cleaning is output through the operation interface.
In the above step, the detection of the dust coverage on the surface of the evaporator 210 in step S604 may be performed in various ways, for example, an image of the surface of the evaporator 210 may be acquired, and the dust coverage on the surface of the evaporator 210 may be determined from the image. In a preferred embodiment, a dust detection sensor may be disposed on the evaporator 210, and the dust coverage may be determined by detecting the thickness of dust on the surface of the evaporator 210.
In step S606, the corresponding interface color is determined according to the dust coverage. Specifically, when the dust coverage rate is less than or equal to a first preset value, determining that the interface color is a first color; when the dust coverage rate is greater than a first preset value and less than or equal to a second preset value, determining that the interface color is a second color; when the dust coverage rate is greater than a second preset value and less than or equal to a third preset value, determining that the interface color is a third color; and when the dust coverage rate is greater than a third preset value, determining that the interface color is a fourth color, wherein the first preset value, the second preset value and the third preset value are sequentially increased, and the first color, the second color, the third color and the fourth color are different.
One embodiment is described below: when the dust coverage rate is less than or equal to 25%, the interface color is green; when the dust coverage rate is more than 25% and less than or equal to 50%, the interface color is blue; when the dust coverage rate is more than 50% and less than or equal to 75%, the interface color is yellow; when the dust coverage is more than 75%, the interface color is red. Note that the default dust coverage is between 0 and 100%, with no cases below 0 and above 100%. The higher dust coverage is shown in red, which can vividly show the situation where the surface of the evaporator 210 is in urgent need of cleaning.
In step S608, the dust coverage and the interface color are output through the operation interface. In a specific embodiment, as shown in fig. 1, a specific number of the dust coverage is shown above the operation interface of the mobile terminal 300, and preferably, the circle box where the number is located may be filled with and displayed with a corresponding interface color. The operation interface of the mobile terminal 300 can output the dust coverage and the interface color at the same time, and the dust coverage of the evaporator 210 is displayed in a form of combining the numbers with the colors, so that the operation interface is more visual and intuitive.
After the self-cleaning process is determined to be finished in step S620, the air conditioner 200 may operate in a normal cooling or heating mode. Further, after determining that the self-cleaning process is ended, step S622 is performed to re-detect the dust coverage and output the dust coverage after self-cleaning through the operation interface. In the self-cleaning method for the evaporator in the air conditioner of the embodiment, the user can know the dust coverage condition of the evaporator 210 in time through the operation interface of the mobile terminal 300, the dust coverage rate of the evaporator 210 is displayed in a form of combining numbers and colors, so that the method is more visual and intuitive, and the dust coverage rate after cleaning can be automatically detected after the self-cleaning process is finished, so that the user can conveniently know the actual condition of the evaporator 210 at any time.
