[0032] Currently, during the power-on operation of the air conditioner, components such as the compressor module in the electronic control box will generate a lot of heat. In order to ensure that the internal electrical components are always in a stable working temperature environment, heat dissipation treatment of the electronic control box is required. Among them, the related technology proposes an electronic control box assembly, including an electronic control box, an outdoor main board, and a main board radiator. The electronic control box is a sealed box body, and both the outdoor main board and the main board radiator are arranged inside the electronic control box. The main board radiator is configured to allow the refrigerant to flow inside it.

[0033] In the related technology, the main board radiator is fixedly attached to the outdoor main board, which can effectively cool the outdoor main board. However, during the operation of the whole machine, due to high-frequency vibration, the main board radiator or its refrigerant pipe group may be broken, which will cause the system refrigerant to leak inside the electronic control box. And since all the electrical components in the electronic control box are powered on, once a large amount of combustible refrigerant accumulates in the box, it is very likely to cause an arc ignition phenomenon between the electrical components, and then trigger dangerous accidents such as fire or even explosion. Therefore, the safety of the related technology still needs to be improved.

[0034] Combined with Figure 1-3 As shown, the embodiments of the present disclosure provide an air conditioner, including: an electronic control box 10, a refrigerant heat dissipation plate 20, and a vibration detection device 30. Among them, the electronic control box 10 has an accommodation cavity 11 internally, and electrical components 50 are installed in the accommodation cavity 11. The refrigerant heat dissipation plate 20 is attached to the electronic control box 10 and is internally provided with a refrigerant pipe group 21. The vibration detection device 30 is arranged on the refrigerant heat dissipation plate 20 and is used to detect the vibration information of the refrigerant heat dissipation plate 20.

[0035] Using the air conditioner provided by the embodiments of the present disclosure, the refrigerant heat dissipation plate 20 is attached to the electric control box 10, and the internal refrigerant pipe group 21 thereof can perform heat exchange with the electrical components 50 in the accommodation cavity 11, so as to achieve the cooling effect of the electric control box 10, and further enable the working environment of the electrical components 50 to always be within a reasonable temperature range, which is beneficial to ensuring the working stability of the air conditioner. In addition, by controlling the vibration detection device 30 to detect the vibration information of the refrigerant heat dissipation plate 20 in real time during the operation of the whole machine, it is possible to determine whether the working state of the refrigerant heat dissipation plate 20 is normal, which is beneficial to the air conditioner to execute the safety warning plan more timely.

[0036] Optionally, the electric control box 10 is provided with a box cover 12 for exposing or closing the accommodation cavity 11. In this way, the user can pull out the box cover 12 when needed to facilitate the maintenance of the electrical components 50 in the accommodation cavity 11.

[0037] Optionally, the electric control box 10 is provided with a window hole 13, and the refrigerant heat dissipation plate 20 is arranged corresponding to the window hole 13. In this way, the refrigerant heat dissipation plate 20 can perform sufficient heat exchange with the electrical components 50 in the accommodation cavity 11 through the window hole 13, so as to achieve the cooling effect of the electric control box 10.

[0038] Optionally, the air conditioner further includes a concentration detection device 40. The concentration detection device 40 is arranged in the accommodation cavity 11 for detecting the refrigerant concentration in the accommodation cavity 11. In this way, the embodiments of the present disclosure can also control the concentration detection device 40 to detect the refrigerant concentration in the accommodation cavity 11 in real time, and can determine whether there is a refrigerant leakage phenomenon in the accommodation cavity 11, which is beneficial to the air conditioner to execute the safety warning plan more accurately.

[0039] Optionally, the air conditioner further includes a control device 50(60) for the air conditioner. The control device 50(60) for the air conditioner is installed in the accommodation cavity 11. In this way, the embodiments of the present disclosure can execute the corresponding control method through the control device 50(60), so as to control the air conditioner to execute the corresponding safety warning plan when the refrigerant heat dissipation plate 20 is in an abnormal state, thereby improving the use safety of the air conditioner.

[0040] Based on the above air conditioner, as shown in combination with Figure 4 The embodiments of the present disclosure provide a control method for an air conditioner, including:

[0041] S401, the processor controls the vibration detection device to obtain the vibration information of the refrigerant heat dissipation plate.

[0042] S402, the processor determines the safety warning plan of the air conditioner according to the vibration information of the refrigerant heat dissipation plate.

[0043] S403, the processor controls the air conditioner to execute the safety warning plan.

[0044] By adopting the control method for an air conditioner provided in the embodiments of the present disclosure, the vibration information of the refrigerant heat dissipation plate during the operation of the whole machine is detected in real time by controlling the vibration detection device, and the working state of the refrigerant heat dissipation plate can be judged whether it is normal. When in an abnormal state, the embodiments of the present disclosure can determine and execute the corresponding safety warning scheme for the air conditioner according to the specific vibration information of the refrigerant heat dissipation plate, so as to reasonably give a warning before the refrigerant leaks, so as to remind the user to perform maintenance in time. Therefore, the embodiments of the present disclosure can reduce the risk of breakage of the refrigerant heat dissipation plate and its refrigerant pipe group, and further can avoid the occurrence of the situation that the combustible refrigerant leaks into the electric control box and causes an explosion accident, which is beneficial to improving the use safety of the air conditioner.

[0045] Optionally, the processor determines the safety warning scheme for the air conditioner according to the vibration information of the refrigerant heat dissipation plate, including: when the vibration acceleration of the refrigerant heat dissipation plate is greater than the first acceleration, the processor determines that the safety warning scheme for the air conditioner is an alarm prompt scheme; and / or, when the vibration acceleration of the refrigerant heat dissipation plate is greater than the second acceleration, the processor determines that the safety warning scheme for the air conditioner is a parameter adjustment compensation scheme; and / or, when the vibration acceleration of the refrigerant heat dissipation plate is greater than the third acceleration, the processor determines that the safety warning scheme for the air conditioner is a shutdown protection scheme. Wherein, the first acceleration is less than the second acceleration, and the second acceleration is less than the third acceleration. In this way, when the vibration acceleration of the refrigerant heat dissipation plate exceeds the first acceleration, it indicates that the refrigerant heat dissipation plate is in an abnormal state at this time, and there is a risk of combustible refrigerant leaking into the electric control box. Therefore, the embodiments of the present disclosure determine that the safety warning scheme for the air conditioner is an alarm prompt scheme, and actively give an alarm to remind the user to perform maintenance in time. When the vibration acceleration of the refrigerant heat dissipation plate exceeds the second acceleration, it indicates that the vibration amplitude of the refrigerant heat dissipation plate is relatively large at this time, and the risk of breakage of the refrigerant heat dissipation plate and its refrigerant pipe group is relatively high, and the risk of leakage of the corresponding flowing refrigerant is also relatively high. Therefore, the embodiments of the present disclosure determine that the safety warning scheme for the air conditioner is a parameter adjustment compensation scheme, and limit the operating parameters of the air conditioner to make the refrigerant heat dissipation plate return to the normal working state as soon as possible, thereby controlling the refrigerant leakage amount of the refrigerant pipe group. And when the vibration acceleration of the refrigerant heat dissipation plate is greater than the third acceleration, it indicates that the refrigerant heat dissipation plate is in an extremely dangerous state at this time, the vibration amplitude is extremely large, and the refrigerant heat dissipation plate and its refrigerant pipe group are very likely to break, resulting in a large amount of combustible refrigerant leaking into the electric control box. Therefore, the embodiments of the present disclosure determine that the safety warning scheme for the air conditioner is a shutdown protection scheme, and shut down for maintenance to avoid causing an explosion accident. Thus, the embodiments of the present disclosure can determine and execute the corresponding safety warning scheme for the air conditioner according to the specific vibration information of the refrigerant heat dissipation plate, which is beneficial to improving the use safety of the air conditioner.

[0046] Optionally, the first acceleration, the second acceleration, and the third acceleration can be set in combination with the air conditioner load condition. Preferably, the first acceleration can be set to 0.5g (acceleration due to gravity), the second acceleration can be set to 0.7g, and the third acceleration can be set to 1.0g to determine the actual working state of the refrigerant heat dissipation plate. The first acceleration, the second acceleration, and the third acceleration can also be adjusted according to the actual needs of the user, or can be set to any other reasonable value.

[0047] Optionally, when it is determined that the safety warning scheme is the alarm prompt scheme, the processor controls the air conditioner to execute the safety warning scheme, including: the processor controls the voice module to broadcast the alarm information; and / or, the processor controls the lighting module to highlight the display; and / or, the processor controls the communication module to send the alarm information to the terminal devices of the user and / or the after-sales personnel. In this way, when it is determined that the safety warning scheme is the alarm prompt scheme, the embodiments of the present disclosure can use some or all of the means such as voice broadcast, lighting display, and SMS notification to give a safety warning to the user and / or the after-sales personnel, which is beneficial for the user and the after-sales personnel to perform maintenance in time and improves the use safety of the air conditioner.

[0048] Optionally, when it is determined that the safety warning scheme is the parameter adjustment and compensation scheme, the processor controls the air conditioner to execute the safety warning scheme, including: the processor reduces the compressor frequency and / or the fan speed until the vibration acceleration of the refrigerant heat dissipation plate is less than or equal to the first acceleration. In this way, when it is determined that the safety warning scheme is the parameter adjustment and compensation scheme, the embodiments of the present disclosure can adjust the working state of the refrigerant heat dissipation plate by restricting the compressor frequency and / or the fan speed, so that it can gradually return to the normal working state, thereby reducing the refrigerant leakage amount of the refrigerant pipe group and avoiding a large amount of combustible refrigerant from leaking into the electric control box, improving the use safety of the air conditioner.

[0049] Optionally, the processor reduces the compressor frequency until the vibration acceleration of the refrigerant heat dissipation plate is less than or equal to the first acceleration, including: at every preset time interval, the processor controls the compressor frequency to be reduced by the first preset frequency until the vibration acceleration of the refrigerant heat dissipation plate is less than or equal to the first acceleration, and / or the compressor frequency drops to the first frequency threshold. In this way, the embodiments of the present disclosure can gradually reduce the compressor frequency in units of the first preset frequency, so that while adjusting the working state of the refrigerant heat dissipation plate, the impact on the user experience can be reduced, which is beneficial to ensuring the user's use requirements.

[0050] Optionally, the first preset frequency can be set in combination with the air conditioner environment condition. Preferably, the first preset frequency can be set to 1Hz to achieve a gradual reduction of the compressor frequency. The first preset frequency can also be adjusted according to the actual needs of the user, or can be set to any other reasonable value.

[0051] Optionally, the first frequency threshold can be set in combination with the environmental conditions of the air conditioner. Preferably, the first frequency threshold can be set to 20 Hz to avoid affecting the user experience. The first frequency threshold can also be adjusted according to the actual needs of the user and can be set to any other reasonable value.

[0052] Optionally, the processor reduces the fan speed until the vibration acceleration of the refrigerant heat dissipation plate is less than or equal to the first acceleration, including: at each preset time interval, the processor controls the fan speed to decrease by a first preset speed until the vibration acceleration of the refrigerant heat dissipation plate is less than or equal to the first acceleration, and / or the fan speed drops to the first speed threshold. In this way, the embodiments of the present disclosure can gradually reduce the fan speed in units of the first preset speed, so as to be able to adjust the working state of the refrigerant heat dissipation plate while reducing the impact on the user experience, which is beneficial to ensuring the user's usage requirements.

[0053] Optionally, the first preset speed can be set in combination with the environmental conditions of the air conditioner. Preferably, the first preset speed can be set to 10 rpm to achieve a gradual reduction of the fan speed. The first preset speed can also be adjusted according to the actual needs of the user and can be set to any other reasonable value.

[0054] Optionally, the first speed threshold can be set in combination with the environmental conditions of the air conditioner. Preferably, the first speed threshold can be set to 100 rpm to avoid affecting the user experience. The first speed threshold can also be adjusted according to the actual needs of the user and can be set to any other reasonable value.

[0055] Optionally, when it is determined that the safety warning plan is the shutdown protection plan, the processor controls the air conditioner to execute the safety warning plan, including: the processor controls the air conditioner to cut off the power supply. In this way, when it is determined that the safety warning plan is the shutdown protection plan, the embodiments of the present disclosure can cut off the power supply of the air conditioner so that the air conditioner stops energized operation in time, thereby being able to avoid the phenomenon of arc ignition between electrical components caused by refrigerant leakage, reducing the risk of explosion accidents of the air conditioner, and improving the usage safety of the air conditioner.

[0056] Optionally, the control method for the air conditioner further includes: when the vibration acceleration of the refrigerant heat dissipation plate is less than or equal to the first acceleration, the processor controls the air conditioner to maintain the current operation mode. In this way, when the vibration acceleration of the refrigerant heat dissipation plate is less than or equal to the first acceleration, the embodiments of the present disclosure determine that the refrigerant heat dissipation plate is in a normal working state. At this time, there is no need to execute the safety warning plan, so the air conditioner maintains the current operation mode to preferentially ensure the user's usage requirements.

[0057] Based on the above air conditioner, as shown in combination with Figure 5 the following, the embodiments of the present disclosure provide another control method for an air conditioner, including:

[0058] S501, the processor controls the vibration detection device to obtain the vibration information of the refrigerant heat dissipation plate.

[0059] S502, the processor determines the safety warning plan of the air conditioner according to the vibration information of the refrigerant heat dissipation plate.

[0060] S503, the processor controls the concentration detection device to obtain the refrigerant concentration in the accommodation chamber.

[0061] S504, the processor corrects the safety warning plan of the air conditioner according to the refrigerant concentration in the accommodation chamber.

[0062] S505, the processor controls the air conditioner to execute the safety warning plan.

[0063] By using the control method for an air conditioner provided in the embodiments of the present disclosure, by controlling the vibration detection device to detect the vibration information of the refrigerant heat dissipation plate in real time during the operation of the whole machine, it is possible to determine whether the working state of the refrigerant heat dissipation plate is normal. When in an abnormal state, the embodiments of the present disclosure can determine and execute the corresponding safety warning plan of the air conditioner according to the specific vibration information of the refrigerant heat dissipation plate, so as to reasonably give a warning before refrigerant leakage to remind the user to perform maintenance in time. Therefore, the embodiments of the present disclosure can reduce the risk of breakage of the refrigerant heat dissipation plate and its refrigerant pipe group, and further can avoid the occurrence of a combustion and explosion accident caused by the leakage of combustible refrigerant into the electric control box, which is beneficial to improving the use safety of the air conditioner. Further, the embodiments of the present disclosure also control the concentration detection device to detect the refrigerant concentration information in the accommodation chamber in real time to determine whether there is refrigerant leakage in the electric control box, so as to reasonably correct the safety warning plan of the air conditioner and execute it more accurately accordingly. Thus, the embodiments of the present disclosure can more accurately identify the refrigerant leakage phenomenon in the electric control box, and further can effectively avoid the combustion and explosion accident through a more powerful safety warning plan, which is beneficial to improving the use safety of the air conditioner.

[0064] Optionally, the processor corrects the safety warning scheme of the air conditioner according to the refrigerant concentration in the accommodation chamber, including: when the refrigerant concentration in the accommodation chamber is greater than the first concentration, the processor corrects the safety warning scheme of the air conditioner to a parameter adjustment compensation scheme; or, when the refrigerant concentration in the accommodation chamber is greater than the second concentration, the processor corrects the safety warning scheme of the air conditioner to a shutdown protection scheme. Wherein, the first concentration is less than the second concentration. In this way, when the refrigerant concentration in the accommodation chamber is greater than the first concentration, it indicates that refrigerant leakage occurs in the accommodation chamber at this time, and there is a risk of arc ignition. Therefore, the embodiment of the present disclosure determines the safety warning scheme of the air conditioner as a parameter adjustment compensation scheme, and reduces the refrigerant leakage amount of the refrigerant pipe group by restricting the operating parameters of the air conditioner, and controls the current and heat generation of the whole machine, thereby facilitating reducing the risk of arc ignition. And when the refrigerant concentration in the accommodation chamber is greater than the second concentration, it indicates that the refrigerant leakage phenomenon occurring in the accommodation chamber at this time is relatively serious, the refrigerant leakage amount is large, and the corresponding risk of arc ignition is also high. Therefore, the embodiment of the present disclosure determines the safety warning scheme of the air conditioner as a shutdown protection scheme, and avoids triggering an explosion accident by shutting down for maintenance. Thus, the embodiment of the present disclosure can determine a more suitable safety warning scheme for the air conditioner according to the refrigerant concentration information in the accommodation chamber and execute it after correction, which is beneficial to further improving the use safety of the air conditioner.

[0065] Optionally, the first concentration and the second concentration can be set in combination with the load condition of the air conditioner. Preferably, the first concentration can be set to 0.1 kg / m 3 , and the second acceleration can be set to 0.3 kg / m 3 to judge the actual refrigerant leakage situation in the accommodation chamber. The first concentration and the second concentration can also be adjusted according to the actual needs of the user, and can also be set to other any reasonable values.

[0066] Optionally, when the safety warning scheme is corrected to a parameter adjustment compensation scheme, the processor controls the air conditioner to execute the safety warning scheme, including: the processor reduces the compressor frequency and / or the fan speed until the refrigerant concentration in the accommodation chamber is less than or equal to the first concentration. In this way, when the safety warning scheme is corrected to a parameter adjustment compensation scheme, the embodiment of the present disclosure can reduce the refrigerant leakage amount of the refrigerant pipe group by restricting the compressor frequency and / or the fan speed, avoid a large amount of combustible refrigerant from leaking into the electric control box, and at the same time can control the current and heat generation of the whole machine, further reducing the risk of arc ignition, which is beneficial to improving the use safety of the air conditioner.

[0067] Optionally, the processor reduces the compressor frequency until the refrigerant concentration in the accommodation chamber is less than or equal to the first concentration, including: at every preset time interval, the processor controls the compressor frequency to be reduced by a second preset frequency until the refrigerant concentration in the accommodation chamber is less than or equal to the first concentration, and / or the compressor frequency is reduced to a second frequency threshold. In this way, the embodiments of the present disclosure can gradually reduce the compressor frequency in units of the second preset frequency, so that while adjusting the refrigerant concentration in the accommodation chamber, the impact on the user experience can be reduced, which is beneficial to ensuring the user's usage requirements.

[0068] Optionally, the second preset frequency can be set in combination with the air conditioner environmental conditions. Preferably, the second preset frequency can be set to 1 Hz to achieve a gradual reduction of the compressor frequency. The second preset frequency can also be adjusted according to the actual needs of the user and can be set to any other reasonable value.

[0069] Optionally, the second frequency threshold can be set in combination with the air conditioner environmental conditions. Preferably, the second frequency threshold can be set to 50 Hz to avoid affecting the user experience. The second frequency threshold can also be adjusted according to the actual needs of the user and can be set to any other reasonable value.

[0070] Optionally, the processor reduces the fan speed until the refrigerant concentration in the accommodation chamber is less than or equal to the first concentration, including: at every preset time interval, the processor controls the fan speed to be reduced by a second preset speed until the refrigerant concentration in the accommodation chamber is less than or equal to the first concentration, and / or the fan speed is reduced to a second speed threshold. In this way, the embodiments of the present disclosure can gradually reduce the fan speed in units of the second preset speed, so that while adjusting the refrigerant concentration in the accommodation chamber, the impact on the user experience can be reduced, which is beneficial to ensuring the user's usage requirements.

[0071] Optionally, the second preset speed can be set in combination with the air conditioner environmental conditions. Preferably, the second preset speed can be set to 10 rpm to achieve a gradual reduction of the fan speed. The second preset speed can also be adjusted according to the actual needs of the user and can be set to any other reasonable value.

[0072] Optionally, the second speed threshold can be set in combination with the air conditioner environmental conditions. Preferably, the second speed threshold can be set to 200 rpm to avoid affecting the user experience. The second speed threshold can also be adjusted according to the actual needs of the user and can be set to any other reasonable value.

[0073] Optionally, when the safety warning scheme is corrected to the shutdown protection scheme, the processor controls the air conditioner to execute the safety warning scheme, including: the processor controls the air conditioner to cut off the power supply. In this way, when the safety warning scheme is corrected to the shutdown protection scheme, the embodiments of the present disclosure can cut off the power supply of the air conditioner, so that the air conditioner stops energized operation in time, thereby avoiding the phenomenon of arc ignition between electrical components accompanied by refrigerant leakage, reducing the risk of explosion accidents of the air conditioner, and improving the use safety of the air conditioner.

[0074] Optionally, the control method for the air conditioner further includes: when the refrigerant concentration in the accommodation cavity is less than or equal to the first concentration, the processor controls the air conditioner to maintain the current safety warning scheme. In this way, when the refrigerant concentration in the accommodation cavity is less than or equal to the first concentration, the embodiments of the present disclosure determine that there is no refrigerant leakage in the electric control box. At this time, there is no need to execute a more powerful safety warning scheme. Therefore, the air conditioner maintains the current safety warning scheme to avoid affecting the user experience.

[0075] Combined with Figure 6 As shown, the embodiments of the present disclosure provide a control device 60 for an air conditioner, including a first acquisition module 61, a determination module 62, and an execution module 63. The first acquisition module 61 is configured to control the vibration detection device to acquire the vibration information of the refrigerant heat dissipation plate; the determination module 62 is configured to determine the safety warning scheme of the air conditioner according to the vibration information of the refrigerant heat dissipation plate; the execution module 63 is configured to control the air conditioner to execute the safety warning scheme.

[0076] By using the control device 60 for the air conditioner provided by the embodiments of the present disclosure, by controlling the vibration detection device to detect the vibration information of the refrigerant heat dissipation plate in real time during the operation of the whole machine, it is possible to determine whether the working state of the refrigerant heat dissipation plate is normal. When in an abnormal state, the embodiments of the present disclosure can determine and execute the corresponding safety warning scheme of the air conditioner according to the specific vibration information of the refrigerant heat dissipation plate, so as to give a reasonable warning before refrigerant leakage to remind the user to perform maintenance in time.
