进一步地,该预设电流值是空调器出厂前预先设定的室内机的风机电流值,即空调器在完全清洁的状态下预设的与环境温度相对应的电流值,该预设电流值更能够反馈空调器在使用过程中的结灰程度,即空调器在使用的过程中始终是和完全清洁状态下的风机电流参数进行比对,在消除环境温度对风机电流影响的基础上,可以更加准确地反馈空调器的结灰程度,在结灰严重时可以及时提示用户需要对空调器进行清洁,在未结灰并且结灰程度在可以接受的范围内时可以暂时不提示用户对空调器进行清洁。Further, the preset current value is a fan current value of the indoor unit that is preset before the air conditioner leaves the factory, that is, a current value preset according to the ambient temperature when the air conditioner is completely clean. The preset current value It can feedback the degree of ash formation in the air conditioner during use, that is, the air conditioner is always compared with the fan current parameters in the completely clean state during use. On the basis of eliminating the impact of ambient temperature on the fan current, it can More accurate feedback of the ashing degree of the air conditioner, it can prompt the user to clean the air conditioner when the ashing is serious, and it can temporarily not prompt the user to the air conditioner when the ashing is not and the ashing degree is within an acceptable range. Clean it.
更进一步地,环境温度值是通过温度传感器检测到的室内机出风口处的温度值,室内机出风口处的温度值最符合环境温度对风机电流的影响,从而使获取的与环境温度值相对应的预设电流值更精准,即使获取的标准电流值更精准,进而使空调器判断需要被清洁的时间节点更加精准。Furthermore, the ambient temperature value is the temperature value at the indoor unit air outlet detected by the temperature sensor. The temperature value at the indoor unit air outlet is most in line with the effect of the ambient temperature on the fan current, so that the obtained value is related to the ambient temperature value. The corresponding preset current value is more accurate, even if the standard current value obtained is more accurate, so that the air conditioner judges the time node that needs to be cleaned more accurately.
又进一步地,提示空调器需要被清洁的方式采取将室内机上的指示灯变为红色可以使用户更为直观地观察到空调器需要被清洁,从而使用户及时对空调器进行人工清洁或开启空调器自清洁模式,避免空调器由于清洁不及时而导致脏堵严重进而影响用户的正常体验。Furthermore, the way of prompting the air conditioner to be cleaned is to change the indicator light on the indoor unit to red, so that the user can more intuitively observe that the air conditioner needs to be cleaned, so that the user can manually clean the air conditioner or turn on the air conditioner in time. The self-cleaning mode of the air conditioner prevents serious blockage of the air conditioner due to untimely cleaning, thereby affecting the normal experience of the user.
此外,本发明在上述技术方案的基础上进一步提供的空调器由于采用了上述的控制方法,因而具备上述控制方法所具备的技术效果,并且相比于现有的空调器,本发明的空调器在需要进行清洁时能够提示用户对空调器进行清洁,从而使空调器能够被及时地清洁,提升用户体验。In addition, the air conditioner further provided by the present invention on the basis of the above technical solution adopts the above-mentioned control method, and therefore has the technical effects of the above-mentioned control method.

具体实施方式detailed description
下面参照附图来描述本发明的优选实施例。本领域技术人员应当理解的是,这些实施例仅仅用于解释本发明的技术原理,并非旨在限制本发明的保护范围。Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention, and are not intended to limit the protection scope of the present invention.
基于背景技术指出的现有空调器10采用人工清洁无法使用户准确地判断何时需要对空调器10进行清洁,从而使空调器10不能被及时地清洁,以及空调器10采用自清洁方式容易使空调器10出现误判而频繁执行自清洁的问题。本发明提供了一种用于空调器10的控制方法及空调器10,旨在使空调器10在需要进行清洁时能够提示用户对空调器10进行清洁,从而使空调器10能够被及时地清洁,进而提升用户体验。The existing air conditioner 10 using manual cleaning based on the background art cannot enable the user to accurately determine when the air conditioner 10 needs to be cleaned, so that the air conditioner 10 cannot be cleaned in a timely manner, and the air conditioner 10 is self-cleaning and easy to use. The air conditioner 10 has a problem of misjudgment and frequently performs self-cleaning. The invention provides a control method for the air conditioner 10 and the air conditioner 10, which aims to enable the air conditioner 10 to prompt the user to clean the air conditioner 10 when cleaning is needed, so that the air conditioner 10 can be cleaned in time. To improve user experience.
具体地,参见图5,本发明的空调器10包括室内机20,如图1所示,本发明的控制方法包括:步骤S102,获取环境温度值;步骤S104,根据环境温度值获取相对应的预设电流值;步骤S106,将预设电流值作为标准电流值;步骤S108,获取室内机20的风机电流值;步骤S110,根据风机电流值和标准电流值,选择性地提示空调器10需要被清洁。需要说明的是,室内机20的风机电流大小能够直接反映出空调器10的结灰程度,因为在一定的环境温度下风机的负荷是确定的,当相同环境温度下风机的负荷增大,相应地,风机电流减小,此时说明风机的风阻增加,也就是说室内机20上结灰,并且结灰越严重,风机电流就越小,因此,通过风机电流大小能够充分地判断空调器10的室内机20的结灰程度。Specifically, referring to FIG. 5, the air conditioner 10 of the present invention includes an indoor unit 20. As shown in FIG. 1, the control method of the present invention includes: Step S102, obtaining an ambient temperature value; Step S104, obtaining a corresponding one according to the ambient temperature value. The preset current value; step S106, using the preset current value as the standard current value; step S108, obtaining the fan current value of the indoor unit 20; step S110, selectively prompting the air conditioner 10 according to the fan current value and the standard current value Be cleaned. It should be noted that the magnitude of the fan current of the indoor unit 20 can directly reflect the degree of ash formation of the air conditioner 10 because the load of the fan is determined at a certain ambient temperature. When the load of the fan increases at the same ambient temperature, the corresponding Ground, the fan current decreases, which means that the wind resistance of the fan increases, that is to say, the ash is formed on the indoor unit 20, and the more serious the ash is, the smaller the fan current is. Therefore, the air conditioner 10 can be fully judged by the magnitude of the fan current. The degree of ash formation of the indoor unit 20 of FIG.
此外,还需要说明的是,上述的预设电流值可以为空调器10出厂前预先设定好的室内机20的风机电流值,即空调器10处于完全清洁的状态下,检测空调器10在不同环境温度下室内机20的风机电流,然后根据检测数据设定温度补偿换算公式或者温度电流对照表,在空调器10运行过程中,获取空调器10的环境温度值后,可以通过预先设定好的温度补偿公式或者温度电流对照表得到与该环境温度值相对应的预设电流值,将该预设电流值作为标准电流值。例如,如果检测数据显示风机电流值与环境温度值呈线性变化关系,则可以根据检测数据设定温度补偿换算公式,选定环境温度变化区间为T1(TI可以为空调器10运行过程中的最低环境温度值)和T2(T2可以为空调器10运行过程中的最高环境温度值),与环境温度值T1和T2相对应的预设电流值分别为I1和I2,T2与T1的差值为△T,I1与I2的差值△I,温度补偿系数k等于△T与△I的比值,在空调器10运行过程中,如果获取的环境温度值为T0,则预设电流值I0等于环境温度值T0乘以温度补偿系数k,即I0=k×T0,将预设电流值I0作为标准电流值。在一种可能的实施例中,通过实验测取环境温度值为0℃时室内机20的风机电流值为I1, 环境温度值为40℃时室内机20的风机电流值为I2,将实验数据存储到空调器10中,在空调器10运行过程中,如果获取的环境温度值为20℃,则相对应的电流值I=〔(I1-I2)/(40℃-0℃)〕×20℃,将计算得到的电流值I作为标准电流值。当然,上述的预设电流值还可以为空调器10出厂后预先设定好的室内机20的风机电流值,即空调器10在使用过程中,按照预先设定的程序,在预设时间内获取与环境温度值相对应的风机电流值,将采集到的环境温度值和风机电流值存储到空调器10内,形成与环境温度值一一对应的风机电流值对照表,即温度电流对照表,温度电流对照表设定完成后,空调器10可以根据该温度电流对照表得到与当前获取的环境温度值相对应的预设电流值,将该预设电流值作为标准电流值,其中,上述的预设时间可以为一天、一周或者一个月等任意设置的时长,只要能够在预设时间内获取与环境温度值相对应的风机电流值即可。In addition, it should be noted that the above-mentioned preset current value may be a fan current value of the indoor unit 20 that is preset before the air conditioner 10 leaves the factory, that is, when the air conditioner 10 is in a completely clean state, it is detected that the air conditioner 10 is at The fan current of the indoor unit 20 under different ambient temperatures, and then set the temperature compensation conversion formula or temperature current comparison table according to the detection data. During the operation of the air conditioner 10, after obtaining the ambient temperature value of the air conditioner 10, it can be set in advance A good temperature compensation formula or temperature and current comparison table obtains a preset current value corresponding to the ambient temperature value, and uses the preset current value as a standard current value. For example, if the test data shows that the fan current value and the ambient temperature change linearly, you can set a temperature compensation conversion formula based on the test data, and select the ambient temperature change interval as T1 (TI can be the lowest value during the operation of the air conditioner 10 Ambient temperature value) and T2 (T2 can be the highest ambient temperature value during the operation of the air conditioner 10), the preset current values corresponding to the ambient temperature values T1 and T2 are I1 and I2, and the difference between T2 and T1 is △ T, the difference between I1 and I2, △ I, and the temperature compensation coefficient k is equal to the ratio of △ T and △ I. During the operation of the air conditioner 10, if the obtained ambient temperature value is T0, the preset current value I0 is equal to the environment. The temperature value T0 is multiplied by the temperature compensation coefficient k, that is, I0 = k × T0, and the preset current value I0 is used as the standard current value. In a possible embodiment, the fan current value of the indoor unit 20 is I1 when the ambient temperature value is 0 ° C, and the fan current value of the indoor unit 20 is I2 when the ambient temperature value is 40 ° C. Stored in the air conditioner 10, during the operation of the air conditioner 10, if the obtained ambient temperature value is 20 ° C, the corresponding current value I = [(I1-I2) / (40 ° C-0 ° C)] × 20 ℃, the calculated current value I is taken as the standard current value. Of course, the above-mentioned preset current value may also be the fan current value of the indoor unit 20 that is preset before the air conditioner 10 leaves the factory, that is, during the use of the air conditioner 10, according to a preset program, within a preset time Obtain the fan current value corresponding to the ambient temperature value, store the collected ambient temperature value and fan current value in the air conditioner 10, and form a fan current value comparison table corresponding to the ambient temperature value, that is, a temperature current comparison table After the temperature and current comparison table is set, the air conditioner 10 may obtain a preset current value corresponding to the currently obtained ambient temperature value according to the temperature and current comparison table, and use the preset current value as a standard current value. The preset time can be arbitrarily set for a day, a week, or a month, as long as the fan current value corresponding to the ambient temperature value can be obtained within the preset time.
优选地,“获取环境温度值”的步骤具体包括:获取室内机20出风口处的温度值。进一步地,或者,“获取室内机20出风口处的温度值”的步骤包括,获取通过温度传感器70检测到的室内机20出风口处的温度值。下面结合具体实施例详细地阐述本发明的技术方案。Preferably, the step of “obtaining an ambient temperature value” specifically includes: obtaining a temperature value at an air outlet of the indoor unit 20. Further, or, the step of "obtaining a temperature value at the air outlet of the indoor unit 20" includes obtaining a temperature value at the air outlet of the indoor unit 20 detected by the temperature sensor 70.

After the panel controller 31 receives the fan current value, calculates the change value of the fan current value relative to the standard current value, and Compare the change value with the preset value (specifically, step S214, determine whether the change value is greater than the preset value). If the change value is greater than the preset value, it prompts the air conditioner 10 It is cleaned (step S216); If the variation is not greater than the preset value, no prompt needs to be cleaned air conditioner 10 (step S218). Specifically, the above-mentioned change value is equal to the difference ΔI between the standard current value Ib and the fan current value If. That is, if the difference ΔI between the standard current value Ib and the fan current value If is greater than a preset value, it is prompted that the air conditioner 10 needs to be cleaned. If the difference △ I between the standard current value Ib and the fan current value If is not greater than the preset value Value, it does not indicate that the air conditioner 10 needs to be cleaned. In a possible embodiment, the preset value is set to 0.1A, that is, if △ I> 0.1A, it means that the dirty blockage of the indoor unit 20 is serious at this time, and the user needs to be prompted to clean the air conditioner 10, if △ If I≤0.1A, it means that there is no dirty blockage of the indoor unit 20 or the dirty blockage of the indoor unit 20 is still within an acceptable range. At this time, the user may not be prompted to clean the air conditioner 10 temporarily. Of course, the preset value is not limited to the above-mentioned example 0.1A. Those skilled in the art can flexibly set the specific value of the preset value in practical applications, as long as the cut-off point determined by the preset value can determine whether the air conditioner 10 needs to be cleaned.

Specifically, the above-mentioned change value is equal to the difference ΔI between the standard current value Ib and the fan current value If. That is, if the difference ΔI between the standard current value Ib and the fan current value If is greater than a preset value, it is prompted that the air conditioner 10 needs to be cleaned. If the difference △ I between the standard current value Ib and the fan current value If is not greater than the preset value Value, it does not indicate that the air conditioner 10 needs to be cleaned. In a possible embodiment, the preset value is set to 0.1A, that is, if △ I> 0.1A, it means that the dirty blockage of the indoor unit 20 is serious at this time, and the user needs to be prompted to clean the air conditioner 10, if △ If I≤0.1A, it means that there is no dirty blockage of the indoor unit 20 or the dirty blockage of the indoor unit 20 is still within an acceptable range. At this time, the user may not be prompted to clean the air conditioner 10 temporarily. Of course, the preset value is not limited to the above-mentioned example 0.1A. Those skilled in the art can flexibly set the specific value of the preset value in practical applications, as long as the cut-off point determined by the preset value can determine whether the air conditioner 10 needs to be cleaned. Just fine.
此外,需要说明的是,室内机20的面板控制器31可以通过调速电压线 将获取的环境温度值传输给室内机20的电机控制器32,调速电压线是空调器10自有的一根传输线,连接在面板控制器31和电机控制器32之间,调速电压线能够传输电压信号,面板控制器31通过调速电压线给电机控制器32传输电压信号以调整电机的转速。本发明将调速电压线传输的电压信号划分为电机调速电压信号和温度通讯电压信号。在一种可能的实施例中,将传输电压值为0V~6.5V的电压信号设置为电机调速电压信号,即当传输电压值在0V~6.5V之间代表的是调速信号,将传输电压值为8V~12V的电压信号设置为温度通讯电压信号,即当传输电压值在8V~12V之间代表的是温度信号,预先设定一个传输电压值与环境温度值一一对应的对照表,即电压温度对照表(如附图4所示),分别存储在面板控制器31和电机控制器32内,如果获取的环境温度值为0℃,面板控制器31通过电压温度对照表(如附图4所示)查得传输电压值为8V,则面板控制器31通过调速电压线传输一个电压值为8V的电压信号到电机控制器32,电机控制器32接收到电压值为8V的电压信号后,通过电压温度对照表(如附图4所示)查得环境温度值为0℃,即通过调速电压线完成环境温度值的传输。当然,传输电压值和环境温度值不仅限于本表(如附图4所示)中的这些数值,本领域技术人员可以在实际应用中灵活的设置传输电压值和环境温度值的具体数值,只要使传输电压值和环境温度值一一对应即可。当然,也可以在面板控制器31和电机控制器32之间新加一条通讯线直接传输温度值,即通过通讯线直接传输温度值,不必再通过电压值进行转换传输,再或者,通过红外温度传输系统来传输温度值,即通过面板控制器31的红外发射头发射温度通信信息,并由电机控制器32的一体化接收头接收温度通信信息,本领域技术人员在实际应用中可以灵活地设置温度传输的具体方式,只要能够将面板控制器31获取的环境温度值传输到电机控制器32即可。In addition, it should be noted that the panel controller 31 of the indoor unit 20 can transmit the obtained ambient temperature value to the motor controller 32 of the indoor unit 20 through a speed regulation voltage line. The speed regulation voltage line is a A transmission line is connected between the panel controller 31 and the motor controller 32. The speed regulating voltage line can transmit a voltage signal. The panel controller 31 transmits a voltage signal to the motor controller 32 through the speed regulating voltage line to adjust the speed of the motor. The invention divides the voltage signal transmitted by the speed regulating voltage line into a motor speed regulating voltage signal and a temperature communication voltage signal. In a possible embodiment, a voltage signal with a transmission voltage value of 0V to 6.5V is set as a motor speed regulation voltage signal, that is, when a transmission voltage value between 0V and 6.5V represents a speed regulation signal, the transmission is performed. The voltage signal with a voltage value of 8V ~ 12V is set as a temperature communication voltage signal, that is, when the transmission voltage value is between 8V ~ 12V, it represents a temperature signal. A comparison table of the transmission voltage value and the ambient temperature value is set in advance. That is, the voltage and temperature comparison table (as shown in FIG. 4) is stored in the panel controller 31 and the motor controller 32 respectively. If the obtained ambient temperature value is 0 ° C, the panel controller 31 uses the voltage and temperature comparison table (such as (Shown in FIG. 4) If the transmission voltage value is found to be 8V, the panel controller 31 transmits a voltage signal with a voltage value of 8V to the motor controller 32 through the speed regulating voltage line. The motor controller 32 receives a voltage value of 8V. After the voltage signal, check the ambient temperature value through the voltage and temperature comparison table (as shown in Figure 4) to 0 ° C, that is, complete the transmission of the ambient temperature value through the speed regulating voltage line. Of course, the transmission voltage value and the ambient temperature value are not limited to these values in this table (as shown in FIG. 4), and those skilled in the art can flexibly set the specific values of the transmission voltage value and the ambient temperature value in actual applications, as long as One-to-one correspondence between the transmission voltage value and the ambient temperature value is sufficient. Of course, a new communication line can also be added between the panel controller 31 and the motor controller 32 to directly transmit the temperature value, that is, the temperature value is directly transmitted through the communication line, and there is no need to convert and transmit the voltage value, or alternatively, through the infrared temperature The transmission system transmits the temperature value, that is, the temperature communication information is transmitted through the infrared transmitting head of the panel controller 31, and the temperature receiving information is received by the integrated receiving head of the motor controller 32. Those skilled in the art can flexibly set it in practical applications. The specific method of temperature transmission is only required to transmit the ambient temperature value acquired by the panel controller 31 to the motor controller 32.
进一步优选地,“提示空调器10需要被清洁”的步骤包括:将室内机20上的指示灯60变为预警颜色,其中,可以通过使室内机20上的指示灯60变为红色或者黄色来提示用户空调器10需要被清洁,本领域技术人员可以在实际应用中灵活地设定指示灯60的具体颜色,只要通过该颜色的选定能够提示用户需要对空调器10进行清洁即可,当然,在实际应用中,还可以通过室内机20上的声音装置(例如蜂鸣器、语音播报器等)发出声音来提示用户空调器10需要被清洁,再或者通过指示灯60和声音装置的组合共 同提示用户空调器10需要被清洁,本领域技术人员可以在实际应用中灵活地设置用户对空调器10进行清洁的具体提示方式,这种对提示方式的调整和改变并不偏离本发明的原理和范围,均应限定在本发明的保护范围之内。Further preferably, the step of “indicating that the air conditioner 10 needs to be cleaned” includes: changing the indicator light 60 on the indoor unit 20 to a warning color, wherein the indicator light 60 on the indoor unit 20 can be changed to red or yellow to Prompts the user that the air conditioner 10 needs to be cleaned. Those skilled in the art can flexibly set the specific color of the indicator 60 in practical applications, as long as the selection of the color can prompt the user to clean the air conditioner 10, of course. In actual applications, a sound device (such as a buzzer, a voice announcer, etc.) on the indoor unit 20 can also be used to prompt the user that the air conditioner 10 needs to be cleaned, or a combination of the indicator light 60 and the sound device The user is reminded that the air conditioner 10 needs to be cleaned. Those skilled in the art can flexibly set the specific prompting method for the user to clean the air conditioner 10 in practical applications. Such adjustments and changes to the prompting method do not deviate from the principle of the present invention. And the scope should be limited within the protection scope of the present invention.
需要说明的是,当用户被提示空调器10需要清洁时可以对空调器10的室内机20单独进行清洁,也可以对空调器10的室内机20和室外机同时进行清洁,因为室内机20出现脏堵时也能够在一定程度上间接反馈出室外机也到了出现脏堵的时限。此外,在本发明中,对空调器10具体的清洁方式可以是人工进行清洁,也可以是启动空调器10的自清洁装置进行清洁。It should be noted that when the user is prompted that the air conditioner 10 needs to be cleaned, the indoor unit 20 of the air conditioner 10 can be cleaned separately, and the indoor unit 20 and the outdoor unit of the air conditioner 10 can be cleaned simultaneously because the indoor unit 20 appears It can also indirectly feedback the outdoor unit to a certain extent when the dirty blockage has reached the time when the dirty blockage occurs. In addition, in the present invention, the specific cleaning method for the air conditioner 10 may be manual cleaning, or it may be a self-cleaning device that starts the air conditioner 10 for cleaning.
