在实现本公开实施例的过程中，发现相关技术中至少存在如下问题：
在空调开启后，真空泵一直以设定的功率进行抽真空降噪，当压缩机以稳定频率运行或节能模式运行时，并未产生较大噪音，此时，真空泵还在持续工作，耗能较高。

本公开实施例中，智能家电设备是指将微处理器、传感器技术、网络通信技术引入家电设备后形成的家电产品，具有智能控制、智能感知及智能应用的特征，智能家电设备的运作过程往往依赖于物联网、互联网以及电子芯片等现代技术的应用和处理，例如智能家电设备可以通过连接电子设备，实现用户对智能家电设备的远程控制和管理。
空调系统一般由室内机和室外机两大部分组成，其中，室外机设置有压缩机、室外换热器和节流装置，室内机设置有室内换热器。在空调运行制冷模式时，通过压缩机排出的冷媒依次经过室外换热器、节流装置和室内换热器，最终回到压缩机重新压缩。在空调运行制热模式时，通过压缩机排出的冷媒依次经过室内换热器、节流装置和室外换热器，最 终回到压缩机重新压缩。
在上述过程中，压缩机是冷媒循环系统的主要动力来源，因此，无论是制冷或制热，压缩机在其工作过程中均会发生振动，振动会产生很大的噪音，尤其是在刚启动压缩机或者高频运转的压缩机，产生的噪音更大，从而给用户造成很大困扰。
如图1所示，本实施例提供一种降噪装置，包括罩壳10，罩壳10罩设在压缩机的外围并与压缩机的外表面之间形成有间隙；真空泵与间隙连通，用于将间隙抽真空。通过设置与该间隙连通的真空泵以在压缩机工作前对该间隙抽真空，从而可以在压缩机的外围构造出真空地带，这样，即使压缩机振动产生了噪音，噪音也无法经由真空地带向外传递，从而实现很好的降噪效果。
在本实施例中，在罩壳10的顶部形成有供连接到压缩机的管路和接线穿过的第一通孔，第一通孔用于供压缩机的排气管、吸气管及压缩机的接线穿过；在第一通孔的边缘向外凸起形成有第一防护管段11，第一防护管段11高出罩壳10的顶表面，其内径与压缩机的排气管、吸气管等相适配。
在本实施例中，真空泵连接到罩壳10的内侧壁上，或，连接到罩壳10的外部。在罩壳10的侧壁面上形成有第二通孔12，第二通孔12的边缘可以向内凸起形成有第二防护管段，真空泵的排气口借助软管连接到第二通孔12上，进而真空泵的进气口与间隙连通，以将间隙内的空气排出，从而可以在压缩机的外围构造出真空环境。其中，为了便于安装罩壳10，在罩壳10的底部设置有螺钉座12。
在一些实施例中，当空调系统接收到启动信号后，控制器控制压缩机首先处于待机状态，此时压缩机不会发出噪音；控制器控制真空泵开始工作，将压缩机与罩壳之间的间隙抽真空，从而在压缩机的外围构造出真空环境，然后控制器再控制压缩机启动，空调系统开始工作。这样，压缩机工作产生的噪音无法经空气传播开来，进而实现压缩机的降噪目的。
在一些实施例中，如图2所示，本公开实施例提供了一种用于空调器降噪的控制方法，包括：
S10：在空调器开机时，处理器100控制真空泵启动；
S20：获取压缩机的排气温度或排气压力；
S30：处理器100根据压缩机的排气温度或排气压力，控制真空泵的电机的运行转速。
在空调开机时，由于压缩机处于低负荷运行时，压缩机运行频率低。此时，压缩机都是处于一种非稳态的情况，压缩机的转矩较大，导致压缩机振动，进而产生噪音。因此，在空调系统刚运行，压缩机运行不稳定且噪音较大，控制真空泵启动进行降噪。随着压缩 机的排气温度逐渐升高或排气压力逐渐增大，真空泵的电机的运行转速加快，进而增加真空泵的功率，可快速抽真空，从而实现很好的降噪效果；当压缩机的排气温度逐渐稳定且噪音较小，此时逐渐减小电机的运行转速。这样，既能满足降噪效果也能降低真空泵的能耗。
可选地，处理器100根据压缩机的排气温度或排气压力，控制真空泵的电机的运行转速。其中，空调器的运行模式不同，排气温度或排气压力需求也不同；为此，精准获取压缩机的排气温度或排气压力影响真空泵的电机的运行转速。本实施例中，空调器设有用于监测压缩机排气处的温度传感器或压力传感器，温度传感器或压力传感器电连接于处理器100并向处理器100实时发送压缩机的排气温度信号或排气压力信号。
在一些实施例中，压缩机的排气温度越高或排气压力越大，真空泵的电机转速越快。
在本实施例中，空调系统具有多个降噪等级L，每个降噪等级对应真空泵中电机的转速n。示例地，空调系统具有10个降噪等级L，L可以是1级、2级、3级、4级、5级、6级、7级、8级、9级和10级。可选地，随着降噪等级的提升，电机的转速逐渐增加。
在本实施例中，当制冷或制热需求较大时，这里，以压缩机的排气温度控制真空泵的电机的运行转速，压缩机需要提升冷媒的排气温度，此时，压缩机是一直是高负荷运转，压缩机的转矩较大，空调系统开启7级降噪，电机的转速以第七转速运行。当制冷或制热需求较减小时，空调系统开启2级降噪，电机的转速以第转速运行，进而既能满足降噪效果也能降低真空泵的能耗。
可选地，如图3所示，处理器100根据压缩机的排气温度或排气压力，控制真空泵的电机的运行转速，包括：
S21：在压缩机的排气温度大于等于第一预设温度，或，压缩机的排气压力大于等于第一预设压力，确定真空泵的电机转速为第一运行转速；
S22：处理器100控制真空泵的电机以第一转速运行。
可选地，第一预设温度的取值范围为65℃至75℃；
在本实施例中，真空泵的电机转速取决于第一预设温度的取值范围。如，第一预设温度为65℃，电机的转速以第四转速运行，空调系统为4级降噪；第一预设温度为70℃，电机的转速以第五转速运行，空调系统为5级降噪；第一预设温度为75℃，电机的转速以第六转速运行，空调系统为6级降噪。
在本实施例中，压缩机的排气温度大于第一预设温度，真空泵的电机转速需要提升至目标转速，才能满足降噪的目的，即真空泵的电机以第一转速运行。
可选地，第一预设压力的取值范围为2.5Mpa至2.5Mpa，其电机转速的调节方式与根 据排气温度的调节方式相同，在此不再赘述。
在本实施例中，空调系统的降噪等级可以根据用户的实际使用需求进行更改，进而改变真空泵的电机转速。
可选地，如图4所示，本公开实施例提供了另一种用于空调器降噪的控制方法，包括：
S31：在空调器开机时，处理器100控制真空泵启动；
S32：获取压缩机的排气温度或排气压力；
S33：处理器100根据压缩机的排气温度或排气压力，控制真空泵的电机的运行转速；
S34：获取压缩机的运行频率；
S35：处理器100根据压缩机的运行频率，控制真空泵的运行设定时长。
在本实施例中，通过压缩机的排气温度或排气压力以及压缩机的运行频率控制真空泵的运行转速和运行时长，能进一步的降低真空泵的能耗。
在本实施例中，压缩机的排气温度或排气压力也可调整压缩机的运行频率，进而控制真空泵的运行设定时长。
在本实施例中，如果压缩机的运行频率始终不稳定，真空泵需要持续工作，以保证压缩机的噪音不会传递至外部环境，但是，当压缩机的的运行频率稳定后，可以通过压缩机的排气温度或排气压力降低真空泵电机的转速，逐渐减小真空泵的功率。
但是，当压缩机以稳定的频率运行时，真空泵的转速降低，为进一步减小真空泵的能耗，也可以直接将真空泵关闭。
在一些实施例中，压缩机的运行频率逐渐升高至设定频率或逐渐降低至设定频率，控制真空泵以第一设定时长运行。
在本实施例中，根据用户的需求，压缩机的运行频率逐渐升高，升高到一定频率后，满足用户的使用需求，并且压缩机的运行频率逐渐趋于稳定频率。真空泵工作的时长是压缩机的运行频率逐渐升高到稳定频率的时长，此时，空调系统内的冷媒稳定和冷媒压力也趋于稳定，压缩机产生的噪音较小，此时，可以将真空泵关闭。
在本实施例中，压缩机的运行频率逐渐降低，降低到一定频率后，压缩机的运行频率逐渐趋于稳定频率，也可以将真空泵关闭。
可选地，如图5所示，处理器100根据压缩机的运行频率，控制真空泵的运行设定时长，包括：
S41：压缩机的以设定的第一运行频率运行且持续运行第一预设时长，确定真空泵关闭；
S42：处理器100将真空泵调整为关闭状态。
在本实施例中，真空泵的运行时长取决于压缩机的运行频率以及压缩机以该运行频率持续运行时长。示例地，第一运行频率的取值范围为30Hz至60Hz。第一预设时长可以为10min、15min或20min。
在本实施例中，若压缩机的运行频率为40Hz且持续运行15min，此时，压缩机的转矩比刚开机时小，进而噪音较小，表明压缩机的运行频率稳定。由于空调器运行时，门窗一般为关闭状态，压缩机的噪音几乎传递不到室内侧，因此产生的噪音并不影响用户，将真空泵关闭，以降低真空泵的能耗。
在本实施例中，压缩机的第一运行频率和第一预设时长需要同时满足才能将真空泵关闭。其中，真空泵的运行时长也可以根据用户的实际使用需求进行更改，保证满足降噪的目的。
在一些实施例中，在空调器为舒适模式、节能模式或睡眠模式运行的情况下，控制真空泵关闭。
在本实施例中，空调器为舒适模式、节能模式或睡眠模式运行的情况下，压缩机的运行频率稳定，并且较小的负荷运行。此时，压缩机的转矩较小，运行的时候振动更小，因此产生的噪音并不影响用户。
这里，以空调器在睡眠模式下运行为例，例如，空调遥控器上设置有睡眠模式的按钮，用户通过按下按钮来启动睡眠模式，或者用户也可以通过与服务器或空调器通讯的用户端来实现睡眠模式的打开，其中，用户端可以为移动终端上安装的APP，移动终端包括但不限于手机、平板电脑等。通过获取压缩机的频率控制真空泵关闭或者在睡眠模式下处理器100直接控制真空泵关闭，这样，既降低真空泵的能耗，又保证空调的冷热效果。
结合图6所示，本公开实施例提供一种用于空调器降噪的装置，包括处理器(processor)100和存储器(memory)101。可选地，该装置还可以包括通信接口(Communication Interface)102和总线103。其中，处理器100、通信接口102、存储器101可以通过总线103完成相互间的通信。通信接口102可以用于信息传输。处理器100可以调用存储器101中的逻辑指令，以执行上述实施例的用于空调器降噪的控制方法。
此外，上述的存储器101中的逻辑指令可以通过软件功能单元的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。

存储器101可包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需的应用程序；存储数据区可存储根据终端设备的使用所创建的数据等。此外，存储器101可以包括高速随机存取存储器，还可以包括非易失性存储器。
