Referring to fig. 1 and 2, the housing of the outdoor unit of the air conditioner includes a chassis 10, and the chassis 10 is provided with a drain port, a detection module 20, and a vibration module 30. And the water outlet is used for discharging condensed water generated by the heat exchanger of the outdoor unit when the air conditioner is used for heating. The detection module 20 is arranged at the water outlet of the chassis of the air conditioner outdoor unit and is used for detecting the light transmittance at the water outlet. And the vibration module 30 is arranged on the chassis at one side of the detection module and is used for generating a vibration source so as to vibrate the chassis. Wherein the vibration module 30 includes a vibrator or other device structure that can generate vibrations.

Optionally, the detection module 20 includes a detection bracket 21, a light emitting end 22, a light receiving end 23, and a lens 24. The detecting bracket 21 includes a first bracket installed at the drain port on the inner side of the chassis 10 and a second bracket installed at the drain port on the outer side of the chassis 10. I.e. the first and second brackets are symmetrically arranged on the inner and outer sides of the chassis 10. The light emitting end 22 is disposed on the first bracket, and emits light into the drain opening. The light receiving end 23 is disposed on the second bracket, and is configured to receive the light emitted by the light emitting end 22. And a lens 24 mounted on the chassis 10 directly below the light emitting end 22, the light of the light emitting end 22 being received by the light receiving end 23 through the lens 24. The detection module 20 works on the principle that: the light emitting end 22 emits light to the lens 24 through the drain opening, and the light is received by the light receiving end 23 through the lens 24, thereby obtaining light transmittance.

Optionally, the water outlet comprises a first water outlet and a second water outlet, and the first water outlet and the second water outlet have a height difference; and each of the water discharge positions is provided with a detection module 20 and a vibration module 30. Here, two outlet are located on different planes, namely the difference in height to detect on the different planes ash layer pile up, freeze, frosting state, thus can realize the anti-blocking of chassis in all-round. In the drawings, the drain port is blocked by the detection module 20, and thus is not shown. It can be understood that the corresponding position of the detection module is the water outlet.

Alternatively, the detection support 21 has a convex structure. Therefore, on one hand, the light emitting end and the light receiving end are convenient to install, and on the other hand, the water outlet space is avoided, so that water is not blocked from being discharged.

Based on the above structure of the outdoor unit, referring to fig. 3, an embodiment of the disclosure provides a control method for an air conditioner outdoor unit, including:

s101, under the condition that the air conditioner is in an operation state, the detection module detects the change condition of the light transmittance at the chassis drain outlet of the outdoor unit.

S102, the processor determines a corresponding control strategy according to the detected light transmittance and the initial light transmittance under the condition that the change of the light transmittance indicates that the light transmittance is reduced.

S103, the processor controls the vibration module of the outdoor unit to execute a control strategy so as to clean the chassis.

When the air conditioner is in operation, the state of the chassis drain outlet of the outdoor unit is detected. This is because, on the one hand, outside air carries dust particles into the inside of the indoor unit by the outdoor unit fan when the air conditioner is in operation. Part of the ash layer is settled on the chassis, and the risk of blocking the water outlet exists. On the other hand, in the air conditioning heating mode, the outdoor heat exchanger is an evaporator. The fins are cold sources, and water vapor in the air can be condensed into water drops when encountering the fins and flows to the chassis along the fins to be discharged through the water outlet. In the process, the water outlet is required to be ensured to be unobstructed. Therefore, in order to ensure stable operation of the outdoor unit, the state of the drain port is detected in real time at least when the air conditioner is in an operating state.

Here, the transmittance of the drain port is detected to obtain a change in transmittance. And preliminarily judging whether the water outlet is abnormal or not according to the change condition of the light transmittance. Specifically, the light transmittance is high when the water outlet is not blocked or frozen, i.e. the light transmittance is relatively high. When the water outlet is blocked or frozen and frosted, light rays can be shielded to influence the transmission of the light rays, so that the light transmittance is reduced. Therefore, when the change in light transmittance indicates a decrease in light transmittance, it is indicated that there is an abnormality in the drain opening. Further, the control strategy can be determined by the magnitude relation between the detection value of the light transmittance of the water outlet and the initial light transmittance. For example, a greater difference indicates a more severe occlusion, and a higher purge capacity is required for the determined control strategy. And then the vibration control module executes the control strategy. The initial light transmittance refers to the light transmittance of the drain opening in a normal state. In addition, there is a difference in transmittance of the outdoor unit due to the difference in installation environment of the air conditioner and the lens. Therefore, the initial light transmittance is different for each outdoor unit, and detection and acquisition are required.

By adopting the control method for the air conditioner outdoor unit, which is provided by the embodiment of the disclosure, when the air conditioner is in operation, the light transmittance of the water outlet is detected. If the drain port is clogged or frosted, light transmittance is lowered. In this case, it is necessary to treat the blockage or frost of the drain port to restore the smoothness of the drain port. The control strategy corresponding to different conditions can be determined by the detected light transmittance and the initial light transmittance. And controls the vibration module to execute a control strategy to eliminate the problem by vibrating. Therefore, the problem is solved through vibration, the comfort level of the indoor temperature is not influenced, and the running reliability of the outdoor unit is improved.

Optionally, in step S102, the processor determines the initial light transmittance by:

after the air conditioner outdoor unit is installed and fixed, the detection module detects the light transmittance of the chassis drain outlet of the outdoor unit.

The processor takes the detected light transmittance as the initial light transmittance.

For new machines, the drain is unobstructed. Therefore, after the outdoor unit is installed, the light transmittance of the chassis drain is detected and taken as the initial light transmittance. Is used for later verification of the situation of water outlet blockage or icing and frosting, etc. When the drain port includes a first drain port and a second drain port, it is necessary to detect initial light transmittance of the two drain ports, respectively. In some embodiments, to improve the accuracy of the detection, the light transmittance at the drain opening is detected multiple times. After the detection values are collated, the initial light transmittance is determined. Thereby avoiding errors in single detection. For example, the light transmittance is detected a plurality of times, and the light transmittance that occurs the most times is set as the initial light transmittance.

Optionally, in step S102, the processor determines a corresponding control policy according to the detected light transmittance and the initial light transmittance, including:

the processor calculates a difference between the initial light transmittance and the detected light transmittance.

And the processor determines a corresponding control strategy under the condition that the difference value is larger than a first preset threshold value and the light transmittance of the water outlet is relatively stable.

Here, in the initial stage of the decrease in light transmittance of the drain opening, on the one hand, the ash layer, frost, snow and the like initially start to accumulate to affect the state of the drain opening. However, the problem is not serious, and the normal operation of the water outlet is not affected. The problem may be solved by vibration force or fan wind force generated during the operation of the outdoor unit. On the other hand, the light transmittance of the drain opening decreases, but the light transmittance thereof has not stabilized at a certain value or a certain section value (i.e., is not relatively stable), and the state of the drain opening cannot be clarified. Therefore, when the difference is larger than the preset threshold value and the light transmittance is relatively stable, the ash layer and the like are accumulated to a certain degree, and the water outlet state can be determined, the corresponding control strategy is determined. In this way, the control strategy can be made more targeted.

As shown in fig. 4, an embodiment of the present disclosure provides another control method for an outdoor unit of an air conditioner, including:

S121, the processor calculates a ratio of the detected light transmittance to the initial light transmittance.

S122, the processor determines the chassis state corresponding to the ratio according to the mapping relation between the ratio interval and the different states of the chassis.

S123, the processor determines a corresponding control strategy according to the chassis state.

It is understood that the ash layer and the frost have different light transmittance when the light beam is established. Typically, the ash layer has a low transmittance and the ice has a higher transmittance than the ash layer. Based on the different light transmittance in the different states, the different states of the chassis can be determined. And further, different control strategies are adopted for different states. And controls the vibration module to execute a control strategy to solve the problem. Specifically, the ratio of the current light transmittance (i.e., the detected light transmittance) of the chassis drain opening to the initial light transmittance is calculated. The larger the ratio, the closer the current light transmittance is to the initial light transmittance, and the better the light transmittance of the water outlet, namely the better the water outlet state. And under the condition of smaller ratio, the water outlet is seriously blocked or frozen and frosted. The relationship between the different states of the chassis drain and the ratio interval can be seen in table 1.

Table 1 mapping relationship between ratio intervals and different states of chassis

Ratio interval	Chassis state
		0.1％-0.5％	Ash layer blockage
0.6％-5％	Snow or frost formation
		10％-12％	Icing and the presence of ash layers
30％-60％	Icing and no ash layer

In the table, the ice conditions are subdivided. When ash layers are present in ice, the light transmittance is further reduced. And when no ash layer exists in the ice, the light transmittance of the ice is relatively high. Thus, the chassis condition may correspond to icing and the presence of a layer of ash when the ratio is between 10% and 12%. Avoiding the occurrence of such a situation as to snow or frost. And further, the chassis state does not correspond to the adopted control strategy, resulting in poor cleaning effect.

Optionally, in step S123, the processor determines a corresponding control policy according to the chassis state, including:

the processor determines that the vibration module is operating at a first power if the chassis condition is icing.

The processor determines that the vibration module is operating at the second power if the chassis condition is ash blocking.

The processor determines that the vibration module operates according to the third power under the condition that the chassis state is frosted or snow accumulated; wherein the first power is greater than the second power, and the second power is greater than the third power.

In the embodiment of the disclosure, chassis states are different, and power of the vibration modules is different. It will be appreciated that the vibratory forces required to clean the chassis are different in different conditions. The vibration force for removing ice is larger than that for removing ash layer blockage, and the vibration force for removing ash layer blockage is larger than that for removing frosting or snow. Therefore, the cleaning effect can be ensured, and the resource waste can be avoided.

As shown in fig. 5, an embodiment of the present disclosure provides another control method for an air conditioner outdoor unit, including:

S204, after the processor presets the duration, the change condition of the light transmittance at the water outlet of the chassis is obtained again.

S205, the processor corrects the control strategy of the vibration module under the condition that the change of the light transmittance indicates that the light transmittance is relatively unchanged.

In an embodiment of the disclosure, the vibration module executes a control strategy to vibrate and remove ash, snow or ice for a period of time. If the cleaning effect is achieved, the light transmittance of the chassis drain outlet is improved and gradually increased. Therefore, after a preset period of time, the change in the acquired light transmittance is detected again. So as to determine whether the current control strategy is feasible or not, and if not, correcting the control strategy. Such as increasing the vibratory force of the vibration module.

Optionally, in step S205, the processor corrects a control strategy of the vibration module, including:

the processor increases the operating power of the vibration module according to a preset amplitude until the maximum operating power is reached.

Here, the preset amplitude is a preset value, and may be 10% of the rated operation power. I.e. the modified power is equal to the sum of the current power and 10% of the rated operating power. In some embodiments, different preset amplitudes are set for different states of the chassis. For example, in an icing condition, the preset amplitude is the first amplitude. In the ash layer blocking state, the preset amplitude is the second amplitude. In the frosting or snow state, the preset amplitude is the third amplitude. Wherein the third amplitude is greater than the second amplitude, and the second amplitude is greater than the first amplitude. Here, since the operating power of the vibration module is relatively high in the icing state, there is little room for the vibration amplitude correction thereof. If modified to a large extent, it is likely that the operating power of the vibration module exceeds its rated operating power.

Furthermore, it can be appreciated that in case the detected change in light transmittance again indicates an increase in light transmittance, the control strategy of the vibration module is maintained; and closing the vibration module under the condition that the detected light transmittance meets the preset condition. The preset condition may be that a difference between the current light transmittance of the drain opening and the initial light transmittance is smaller than a second preset threshold. For example, if the initial light transmittance is 100, the second preset threshold takes on a value of 5. Wherein the second preset threshold is smaller than the first preset threshold. Thus, after the problems of light transmittance of the water outlet, blockage or ice and snow accumulation and the like are solved, the vibration module is closed.

As shown in fig. 6, an embodiment of the present disclosure provides another control method for an air conditioner outdoor unit, including:

s601, under the condition that the air conditioner is in an operation state, the detection module detects the change condition of light transmittance at each water outlet of the outdoor unit chassis.

S602, when the change condition of the light transmittance of any water outlet indicates that the light transmittance is reduced, the processor determines a corresponding control strategy according to the detected light transmittance and the initial light transmittance of the water outlet.

S603, the processor controls each vibration module of the outdoor unit to execute a control strategy so as to clean the chassis.

The embodiment of the disclosure aims at the condition that the outdoor unit chassis is provided with a plurality of water outlets. As described above, in order to ensure the smoothness of the drainage of the outdoor unit, the drainage openings are provided at different height planes. The water outlets on different height planes are located at different positions of the chassis of the outdoor unit, which means that the blocking conditions of the water outlets may be different or the same. In the same case, the control can be performed by the aforementioned control method. In a different case, if there is a drain port whose light transmittance is reduced, the state of the chassis is determined based on the light transmittance of the drain port. And further starting each vibration module to execute a control strategy according to the state of the chassis. Here, activating each vibration module means controlling the operation of the vibration modules of all the drain ports. Thus, the cleaning efficiency of the water outlet is improved, and the hidden trouble of other water outlets is avoided. In some embodiments, the light transmittance of the plurality of drain openings is reduced, and the corresponding control strategy can be determined and executed based on the light transmittance of each drain opening and the initial light transmittance thereof.

As shown in fig. 7, an embodiment of the present disclosure provides an apparatus for controlling an outdoor unit of an air conditioner, including a detection module 71, a determination module 72, and a control module 73.

By adopting the control device for the air conditioner outdoor unit, which is provided by the embodiment of the disclosure, when the air conditioner is in operation, the light transmittance of the water outlet is detected. If the drain port is clogged or frosted, light transmittance is lowered. In this case, it is necessary to treat the blockage or frost of the drain port to restore the smoothness of the drain port. The control strategy corresponding to different conditions can be determined by the detected light transmittance and the initial light transmittance. And controls the vibration module to execute a control strategy to eliminate the problem by vibrating. Therefore, the problem is solved through vibration, the comfort level of the indoor temperature is not influenced, and the running reliability of the outdoor unit is improved.
