The air conditioner outdoor unit further comprises a detection device, the icing condition on the chassis 1, such as icing, icing amount and the like, is detected through the detection device, the work of the heating device is indicated according to the detection result of the detection device, and when the chassis 1 is not iced or the icing amount is small and not enough to influence the rotation of the fan blades of the fan 2, the heating device is not started (the control method is specifically explained later), so that electric energy is greatly saved. For example, the detection device and the heating device are both connected with the controller, the controller controls whether the heating device is started or not according to the icing condition detected by the detection device, and the controller can be arranged independently or integrated with a control panel of the air conditioner.
In one embodiment, the detection device includes an icing sensor, such as an optical icing sensor, an electrical icing sensor, a mechanical icing sensor, and the like, the icing sensor can directly feed back parameters (such as icing thickness) related to icing amount and whether icing occurs on the chassis 1 to a controller of the air conditioner, and the controller can judge whether the heating device needs to be turned on according to the fed back information.
In another embodiment, after the chassis 1 of the indoor unit is frozen, the stress condition of the chassis 1 may change, and the freezing condition on the chassis 1 may be reflected according to the stress condition of the chassis 1, based on which, the detecting device includes a stress detecting element for detecting the stress condition of the chassis 1, and the freezing condition on the chassis 1 may be determined according to the stress condition of the chassis 1 detected by the stress detecting element.
The detection device may be, for example, the pressure sensor 5, and the icing condition on the chassis 1 is determined by the pressure detected by the pressure sensor 5 to control the heating device, specifically, a pressure threshold may be preset, if the pressure detected by the pressure sensor 5 is greater than the preset pressure threshold, it indicates that the chassis 1 needs to be iced, the heating device is controlled to be turned on, and if the pressure detected by the pressure sensor 5 is less than or equal to the preset pressure threshold, it indicates that the chassis 1 does not need to be iced, the heating device is controlled to be turned off. The preset pressure threshold may be set according to a setting position of the pressure sensor 5 and a specific ice melting requirement, the setting position of the pressure sensor 5 may be, for example, as shown in fig. 1, on the upper surface of the chassis 1, the pressure sensor 5 senses a pressure generated by ice on the pressure sensor, the pressure sensor 5 is, for example, disposed between the bracket and the chassis 1, the pressure sensor senses a pressure generated by ice together with a portion of the air conditioner outdoor unit on the chassis 1, the chassis 1 is, for example, provided in a double-layer structure including upper and lower chassis units, and the pressure sensor 5 is disposed between the two chassis units, and the pressure sensor 5 senses a pressure generated by the upper chassis unit, ice and a portion of the air conditioner outdoor unit on the chassis 1. In this way, if the installation position of the pressure sensor 5 is different, the preset pressure threshold value is also different. The specific ice melting requirement can be set to that the heating device is turned on to heat the chassis once ice exists on the chassis 1, or the heating device is turned on to heat the chassis 1 when the ice on the chassis 1 exceeds a certain amount, and the heating device is not required to be turned on when the ice on the chassis 1 is less, so that the energy consumption is further reduced.
Of course, it should be understood that the detection device may be other detection devices capable of detecting the stress condition of the chassis 1, for example, a stress sheet or a strain gauge provided on the chassis 1, and the icing condition on the chassis 1 may also be determined based on changes in the stress and strain of the chassis 1 detected by the stress sheet or the strain gauge.
In order to further ensure the accuracy of the detection result, it is preferable that the detection device further includes a temperature detection element (not shown in the figure) for detecting an ambient temperature, a predetermined temperature is set, when the ambient temperature detected by the temperature detection element is lower than the predetermined temperature, the icing condition on the chassis 1 is obtained according to the stress condition of the chassis 1 detected by the stress detection element, when the ambient temperature detected by the temperature detection element is equal to or higher than the predetermined temperature, it indicates that the chassis 1 is not iced, and at this time, the heating device is controlled to be always in the off state, so as to effectively prevent the heating device from being operated by other foreign matters falling on the pressure sensor 5. The predetermined temperature is preferably in the range of-5 deg.C to 5 deg.C, more preferably-1 deg.C to 1 deg.C, for example, in one specific embodiment, the predetermined temperature is 0 deg.C. The temperature detection element may be, for example, a bulb.

Since the heating device is provided for the purpose of avoiding damage to the fan blades caused by ice on the chassis 1, it is preferable that the detection device is provided on the chassis 1 at a position corresponding to the fan 2, for example, the detection device is provided right below the fan 2, as shown in fig. 1.
The control method of the air conditioner outdoor unit may be, for example: when the detection device detects that the chassis 1 is not frozen, the heating device is controlled to be in a closed state, and when the detection device detects that the chassis 1 is frozen, the heating device is controlled to be started.
Further preferably, when the detection device detects that the chassis 1 is frozen, whether the ice amount on the chassis 1 is larger than a predetermined amount is further judged, if yes, the heating device is controlled to be started, otherwise, the ice amount on the chassis 1 is judged to be small, the normal operation of the fan 2 cannot be influenced, and the heating device is still controlled to be in a closed state. For example, when the detection device is a strain gauge, the ice formation amount can be reflected by the strain magnitude of the strain gauge, and when the detection device is a strain gauge, the ice formation amount can be reflected by the stress magnitude of the strain gauge. The predetermined amount may be set according to the type of the detecting device, the specific type of the outdoor unit of the air conditioner, the distance between the fan 2 and the chassis 1, and other factors.
Further preferably, the heating power of the heating device can be controlled according to the icing amount on the chassis 1, when the icing amount is small, the heating power of the heating device can be properly reduced, and when the icing amount is large, the heating power of the heating device is properly increased, so that the power consumption of the air conditioner is further reduced by reasonably controlling the heating power of the heating device.
