Description

用于空调器的控制方法及空调器Control method for air conditioner and air conditioner 技术领域Technical field
本发明属于空调器技术领域,具体提供一种用于空调器的控制方法及空调器。The invention belongs to the technical field of air conditioners, and specifically provides a control method for an air conditioner and an air conditioner.
背景技术Background technique
空调器是能够为室内制冷/制热的设备,随着时间的推移,空调器的室内机和室外机上的积灰会逐渐增多,积灰累积到一定程度后会滋生大量的细菌,尤其在室内空气流经室内机时,会携带大量的灰尘和细菌,因此需要对空调器及时进行清洁。The air conditioner is a device capable of cooling / heating the room. As time goes by, the ash accumulation on the indoor and outdoor units of the air conditioner will gradually increase. After the ash accumulation has accumulated to a certain extent, a large number of bacteria will grow, especially indoors. When the air flows through the indoor unit, it will carry a lot of dust and bacteria, so the air conditioner needs to be cleaned in time.
目前,空调器的清洁一般需要通过人工进行清洁或者通过按键启动自清洁装置进行清洁,但是由于用户不能很准确地判断空调器何时需要进行清洁,导致空调器不能被及时地清洁,从而影响用户的使用体验。现在的一些空调器也有采用自清洁的方式,例如公开号为CN107525209A的专利中公开了一种空调器自清洁控制方法,具体而言,该控制方法包括检测空调器当前的运行模式,若空调器当前的运行模式为非制冷模式,将空调器调整为制冷模式;检测空调器的室内机风机的电机的转速及电机在转速下的第一电流值;将电机在转速下的第一电流值与在转速下的第一预设电流值进行比较,若第一电流值小于或等于第一预设电流值,则开启空调器的自清洁模式,执行室内机换热器的自清洁处理。也就是说,上述的专利中采用的是通过室内机的风机电流来判断是否执行室内机的自清洁,然而,室内机的导板位置会影响室内机的风机电流,导板的开口角度越小,室内机的出风量越小,风机的负荷越大,相应地,风机电流越小,因此,如果只通过室内机风机电流的单一条件判断无法确定室内机的电流降低到底是由于空调器的导板位置产生还是由于空调器的结灰产生,如果空调器仅仅是由于室内机的导板开口角度变小而使室内机的风机电流降低,那么可能会出现室内机在未结灰的情况下空调器仍然会对室内机进行自清洁,这就会造成能源上的浪费。At present, the cleaning of an air conditioner generally requires manual cleaning or a self-cleaning device activated by pressing a button. However, because the user cannot accurately determine when the air conditioner needs to be cleaned, the air conditioner cannot be cleaned in a timely manner, thereby affecting the user. Experience. Some current air conditioners also adopt a self-cleaning method. For example, a patent disclosed in CN107525209A discloses a self-cleaning control method for an air conditioner. Specifically, the control method includes detecting a current operating mode of the air conditioner. The current operating mode is a non-cooling mode, and the air conditioner is adjusted to a cooling mode; the speed of the motor of the indoor unit fan of the air conditioner and the first current value of the motor at the speed are detected; and the first current value of the motor at the speed and the The first preset current value at the rotation speed is compared. If the first current value is less than or equal to the first preset current value, the self-cleaning mode of the air conditioner is turned on, and the self-cleaning process of the indoor unit heat exchanger is performed. That is, in the above patent, the fan current of the indoor unit is used to determine whether to perform self-cleaning of the indoor unit. However, the position of the guide plate of the indoor unit will affect the fan current of the indoor unit. The smaller the opening angle of the guide plate, the indoor The smaller the air output of the unit, the larger the load of the fan, and accordingly, the smaller the fan current. Therefore, if it is judged by the single condition of the fan current of the indoor unit, it cannot be determined whether the current drop of the indoor unit is due to the position of the air conditioner guide plate It is still due to the ash formation of the air conditioner. If the air conditioner only reduces the fan current of the indoor unit due to the opening angle of the guide plate of the indoor unit being reduced, it may happen that the indoor unit will still be The indoor unit performs self-cleaning, which will cause energy waste.
因此,本领域需要一种用于空调器的控制方法及相应的空调器来解决上述问题。Therefore, there is a need in the art for a control method for an air conditioner and a corresponding air conditioner to solve the above problems.

进一步地,标准电流值为空调器处在完全清洁且导板处在设定位置时室内机的风机电流值,在空调器处于完全清洁的状态时,此时选取标准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,在消除导板位置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 standard current value is the fan current value of the indoor unit when the air conditioner is completely clean and the guide plate is in the set position. When the air conditioner is completely clean, selecting the standard current value at this time can better feedback the air conditioner. The degree of ash during use, that is, the air conditioner is always compared with the fan current parameters in a completely clean state during use. Based on eliminating the influence of the position of the guide plate on the fan current, the air conditioner can be more accurately fed back. The degree of ash formation can prompt the user to clean the air conditioner when the ash formation is serious. When the ash is not formed and the ash formation level is within an acceptable range, the user can be temporarily not prompted to clean the air conditioner.
更一步地,将导板的设定位置设置为室内机上电时导板所处的默认位置,即室内机上电后,导板会有一个初始的默认位置,将此时导板的默认位置设置为导板的设定位置,从而不必再单独设定导板位置。Further, the setting position of the guide plate is set to the default position of the guide plate when the indoor unit is powered on, that is, after the indoor unit is powered on, the guide plate has an initial default position, and the default position of the guide plate at this time is set to the setting of the guide plate. Position, so there is no need to set the guide plate position separately.
再进一步地,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. Compared with the existing air conditioner, the air conditioner of the present invention When cleaning is required, the user can be prompted to clean the air conditioner, so that the air conditioner can be cleaned in time, and the user experience is improved.

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3,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,获取导板50在设定位置时室内机20的风机电流值;步骤S104,根据风机电流值,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,因为在导板50位置固定的情况下风机40的负荷是确定的,如果当导板50处于相同位置时风机40的负荷增大,相应地,风机电流减小,此时说明风机40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. 3, 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 a fan current value of the indoor unit 20 when the guide plate 50 is at a set position; In step S104, the air conditioner 10 is selectively prompted to be cleaned according to the fan current value. 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 40 is determined when the position of the guide plate 50 is fixed. The load of 40 is increased, and the current of the fan is reduced accordingly. At this time, the wind resistance of the fan 40 is increased, that is, the ash is formed on the indoor unit 20, and the more serious the ash is, the smaller the fan current is. The size can sufficiently determine the degree of ash formation of the indoor unit 20 of the air conditioner 10.
优选地,“获取导板50在设定位置时室内机20的风机电流值”的步骤包括:室内机20初始上电时,导板50处在默认位置上,获取此时室内机20的风机电流值,即,室内机20初始上电时,导板50会有一个初始的默认位置,当导板50到达默认位置时检测室内机20的风机电流。当然,作为替代性地,“获取导板50在设定位置时室内机20的风机电流值”的步骤还可以包括:使导板50处在设定位置,获取此时室内机20的风机电流值,即,先检测导板50的位置,然后将导板50调整到设定位置后再检测室内机20的风机电流;再或者,“获取导板50在设定位置时室内机20的风机电流值”的步骤又可以包括:当导板50到达设定位置时获取此时室内机20的风机电 流值,即,在检测室内机20的风机电流前无需主动调整导板50位置,仅需等导板50到达设定位置时检测室内机20的风机电流即可,本领域技术人员可以在实际应用中灵活地设置检测风机电流时导板50的具体位置以及在检测风机电流前是否需要先将导板50调整到设定位置,例如检测风机电流时导板50可以处在室内机20初始上电时默认的导板位置,也可以处在导板50开口角度最大的位置或者其他设定的具体位置,当导板50到达设定位置时可以触发空调器10的控制器30检测获取室内机20的风机电流,或者先将导板50调整到设定位置后再检测室内机20的风机电流,只要能够获取导板50在设定位置时室内机20的风机电流值即可,这种对室内机20的风机电流值采样时导板50的具体位置以及采样前是否需要先主动将导板50调整到设定位置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。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 the fan current value of the indoor unit 20 when the guide plate 50 is at a set position" includes: when the indoor unit 20 is initially powered on, the guide plate 50 is at a default position, and the fan current value of the indoor unit 20 is obtained at this time. That is, when the indoor unit 20 is initially powered on, the guide plate 50 will have an initial default position, and when the guide plate 50 reaches the default position, the fan current of the indoor unit 20 is detected. Of course, as an alternative, the step of “obtaining the fan current value of the indoor unit 20 when the guide plate 50 is at the set position” may further include: placing the guide plate 50 at the set position to obtain the fan current value of the indoor unit 20 at this time, That is, the position of the guide plate 50 is detected first, and then the fan current of the indoor unit 20 is detected after the guide plate 50 is adjusted to the set position; or, the step of "obtaining the fan current value of the indoor unit 20 when the guide plate 50 is at the set position" It may also include: obtaining the fan current value of the indoor unit 20 when the guide plate 50 reaches the set position, that is, there is no need to actively adjust the position of the guide plate 50 before detecting the fan current of the indoor unit 20, and only wait for the guide plate 50 to reach the set position The fan current of the indoor unit 20 can be detected at that time. Those skilled in the art can flexibly set the specific position of the guide plate 50 when detecting the fan current and whether the guide plate 50 needs to be adjusted to the set position before detecting the fan current. For example, when detecting the fan current, the guide plate 50 may be at the default guide plate position when the indoor unit 20 is initially powered on, or at the position where the opening angle of the guide plate 50 is the largest, or other When the guide plate 50 reaches the set position, the controller 30 of the air conditioner 10 can be triggered to detect and obtain the fan current of the indoor unit 20, or the guide plate 50 is adjusted to the set position before detecting the fan current of the indoor unit 20. As long as the fan current value of the indoor unit 20 can be obtained when the guide plate 50 is at the set position, the specific position of the guide plate 50 when sampling the fan current value of the indoor unit 20 and whether the guide plate 50 needs to be actively adjusted before sampling. The adjustment and change of the setting position do not deviate from the principle and scope of the present invention, and should be limited to the protection scope of the present invention. The technical solution of the present invention is described in detail below with reference to specific embodiments.
优选地,如图2所示,“根据风机电流值,选择性地提示空调器10需要被清洁”的步骤具体包括:步骤S204,判断风机电流值相对于标准电流值的变化值是否大于预设值。也即是,将风机电流值相对于标准电流值的变化值与预设值比较;根据比较结果,选择性地提示空调器10需要被清洁。进一步地,“根据比较结果,选择性地提示空调器10需要被清洁”的步骤包括:如果变化值大于预设值,则提示空调器10需要被清洁(步骤S206);如果变化值不大于预设值,则不提示空调器10需要被清洁(步骤S208)。具体地,上述的变化值等于标准电流值Ib与风机电流值If的差值△I。即,如果标准电流值Ib与风机电流值If的差值△I大于预设值,则提示空调器10需要被清洁,如果标准电流值Ib与风机电流值If的差值△I不大于预设值,则不提示空调器10需要被清洁。在一种可能的实施例中,预设值设置为0.1A,即如果△I>0.1A,则说明此时室内机20的脏堵比较严重,需要提示用户对空调器10进行清洁,如果△I≤0.1A,则说明此时室内机20无脏堵或者室内机20的脏堵仍然在可以接受的范围内,此时可以暂时不提示用户对空调器10进行清洁。当然,预设值不限于上述示例的0.1A,本领域技术人员可以在实际应用中灵活地设置预设值的具体数值,只要通过预设值确定的分界点能够判断空调器10是否需要被清洁即可。Preferably, as shown in FIG. 2, the step of “selectively prompting the air conditioner 10 to be cleaned according to the current value of the fan” specifically includes: Step S204, determining whether the change value of the current value of the fan relative to the standard current value is greater than a preset value value. That is, the change value of the fan current value relative to the standard current value is compared with a preset value; according to the comparison result, the air conditioner 10 is selectively prompted to be cleaned. Further, the step of “selectively prompting the air conditioner 10 to be cleaned according to the comparison result” includes: if the change value is greater than a preset value, prompting the air conditioner 10 to be cleaned (step S206); if the change value is not greater than the preset value If the value is set, the air conditioner 10 is not prompted to be cleaned (step S208). 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,还需要说明的是,上述的标准电流值可以在空调器10出厂前进行测定,即空调器10处于完全清洁的状态下,测定导板50处于设定位置时 室内机20的标准电流值。此外,标准电流值还可在空调器10出厂后进行测定,即空调器10在使用过程中,将预设时间内获取的导板50处于设定位置时室内机20的多个风机电流值中出现频次最高的电流值作为标准电流值,通过对多个风机电流值出现频次的计算和排序,来选取出现频次最高的风机电流值作为标准电流值,其中,风机电流值的采样数据可以为1000个、2000个或者其他数量,本领域技术人员可以在实际应用中灵活地设置风机电流值的采样数量。而预设时间可以是一天、一周、一个月或者其他设定的时间数值,只要从预设时间内获取的多个风机电流值能够选定出标准电流值即可,这种对预设时间具体数值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。In addition, it should be noted that the above-mentioned standard current value can be measured before the air conditioner 10 leaves the factory, that is, when the air conditioner 10 is in a completely clean state, the standard current value of the indoor unit 20 is measured when the guide plate 50 is in the set position. In addition, the standard current value can also be measured after the air conditioner 10 leaves the factory. That is, during the use of the air conditioner 10, when the guide plate 50 obtained in a preset time is at a set position, it appears in multiple fan current values of the indoor unit 20. The highest frequency current value is used as the standard current value. By calculating and sorting the frequency of occurrence of multiple fan current values, the highest frequency fan current value is selected as the standard current value. Among them, the sampling data of the fan current value can be 1,000. , 2000 or other numbers, those skilled in the art can flexibly set the sampling number of fan current values in practical applications. The preset time can be one day, one week, one month, or other set time value, as long as a plurality of fan current values obtained from the preset time can select a standard current value, which is specific to the preset time The adjustment and change of the values do not deviate from the principle and scope of the present invention, and should be limited to the protection scope of the present invention.
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.
此外,本发明的空调器10还包括控制器30,该控制器30配置成能够执行上述的控制方法。即该控制器30能够帮助用户准确地判断空调器10是否需要被清洁,当空调器10需要被清洁时能够提示用户,从而使空调器10能够被及时地清洁。In addition, the air conditioner 10 of the present invention further includes a controller 30 configured to be able to execute the above-mentioned control method. That is, the controller 30 can help the user accurately determine whether the air conditioner 10 needs to be cleaned, and can prompt the user when the air conditioner 10 needs to be cleaned, so that the air conditioner 10 can be cleaned in time.
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.
至此,已经结合附图所示的优选实施例描述了本发明的技术方案,但是,本领域技术人员容易理解的是,本发明的保护范围显然不局限于这些具体实 施例。在不偏离本发明的原理的前提下,本领域技术人员可以对相关技术特征作出等同的更改或替换,这些更改或替换之后的技术方案都将落入本发明的保护范围之内。So far, the technical solution of the present invention has been described with reference to the preferred embodiments shown in the accompanying drawings. However, those skilled in the art can easily understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or replacements to related technical features, and the technical solutions after these changes or replacements will fall within the protection scope of the present invention.
