Description

TECHNICAL FIELD

[0001] The present application relates to the field of air conditioning technology, in particular to a control method of a mobile air conditioner and the mobile air conditioner. BACKGROUND

[0002] At present, some air conditioners adopt the combination scheme of fixed frequency compressor and DC motor, and often choose to skip the step of judging the compressor frequency, and directly investigate the higher priority outdoor environment temperature. The principle is that the variable frequency air conditioner usually detects the value of the outdoor environment temperature to determine the change of the compressor frequency, and then indirectly controls the speed level change of the DC motor. When adopting the fixed frequency compressor, the link of compressor frequency change can be skipped, and the outdoor environment temperature and the DC motor level are directly taken as function variables for control. However, on the fixed frequency mobile air conditioner, due to the special configuration of the mobile air conditioner, this way cannot be adopted. The biggest difference between the mobile air conditioner and the conventional split air conditioner is that the whole machine body is located on the indoor side, including the heat exchanger, and is connected together with the outdoor side through the air pipe. This results in that the mobile air conditioner cannot accurately detect the accurate outdoor temperature value, and even for some single air pipe models, the outdoor temperature value cannot be detected at all. Therefore, on the fixed frequency mobile air conditioner, the speed regulation mode of the motor needs to be considered, and a new reference variable is selected to adjust the speed of the DC motor.

Thus, the features defined with "first", "second" can explicitly or implicitly include at least one of the features, i.e. one or more of the features. In the description of the present application, the meaning of "a plurality of" is at least two, for example two, three, etc., unless otherwise specifically limited. When a certain feature "includes or comprises" a certain or certain features, unless otherwise specifically described, it indicates that other features are not excluded and can further include other features.

Furthermore, the described particular features, structures, materials, or characteristics can be combined in any suitable manner in one or more embodiments or examples.

[0040] In the prior art, when a fixed frequency mobile air conditioner adopts a DC motor scheme, there is a contradiction: the DC motor usually has the advantage of adjustable speed in multiple gears, and if it runs at a fixed wind speed, it has no advantage over ordinary AC iron shell motors; but for a fixed frequency mobile air conditioner, since the compressor runs at a fixed frequency, it cannot adjust the wind speed level according to the frequency change of the variable frequency compressor like a common variable frequency air conditioner. In other words, the DC motor needs to find another basis for adjusting the wind speed.

[0041] Figure 1 is a schematic flow chart of a control method of a mobile air conditioner according to an embodiment of the present disclosure, as Figure 1 shown, the present embodiment provides a control method of a mobile air conditioner, including the following steps:

[0042] Step S1: Obtain the indoor environment temperature.

[0043] Step S2: Determine the wind speed of the outdoor fan according to the indoor environment temperature.

[0044] In the present embodiment, after the mobile air conditioner enters the cooling state, the present disclosure provides a technical means for determining the wind speed of the outdoor fan of the mobile air conditioner according to the indoor environment temperature, solving the problem that the fixed frequency mobile air conditioner cannot adjust the speed of the DC motor according to the outdoor environment temperature.

[0045] Through the control method of the present embodiment, the present disclosure can accurately adjust the wind speed of the fixed frequency mobile air conditioner according to the indoor environment temperature, improving the user experience.

[0046] In some embodiments of the present disclosure, determining the wind speed of the outdoor fan according to the indoor environment temperature includes: determining the wind speed of the outdoor fan according to the indoor environment temperature and the target set temperature.

[0047] In the present embodiment, the present disclosure provides a technical means for determining the wind speed of the outdoor fan according to the relationship between the difference between the indoor environment temperature and the target set temperature and the preset temperature. That is, according to the different relationship between the difference between the indoor environment temperature and the target set temperature and the preset temperature, the wind speed of the outdoor fan is adjusted to the corresponding wind speed level.

[0048] wherein the indoor environment temperature is a temperature obtained by the sensor, and the target setting temperature is a temperature set by the user for the mobile air conditioner.

[0049] Through the control method of the embodiment, the application can accurately adjust the wind speed of the fixed-frequency mobile air conditioner according to the relationship between the temperature variation of the indoor environment temperature and the preset temperature, thereby improving the user experience.

[0050] In some other embodiments of the application, the wind speed of the outer fan is determined according to the indoor environment temperature, comprising: determining the wind speed of the outer fan according to the temperature variation degree of the indoor environment temperature.

[0051] Preferably, the temperature variation degree of the indoor environment temperature comprises a temperature variation rate of the indoor environment temperature.

[0052] In the embodiment, the application provides a technical means for determining the wind speed of the outer fan according to the temperature variation degree of the indoor environment temperature. That is, the wind speed of the outer fan is adjusted according to the relationship between the temperature variation of the indoor environment temperature and the preset temperature within a preset time. When switching between the wind speed levels of the outer fan, a first preset time interval is required to prevent the wind speed level from frequently jumping, and the first preset time interval is 20s, which can be adjusted according to actual needs.

[0053] Through the control method of the embodiment, the application can accurately adjust the wind speed of the fixed-frequency mobile air conditioner according to the relationship between the temperature variation of the indoor environment temperature and the preset temperature, thereby improving the user experience.

[0054] In some other embodiments of the application, the wind speed of the outer fan is determined according to the indoor environment temperature, comprising: determining the wind speed of the outer fan according to the temperature variation degree of the indoor environment temperature, and a preset relationship between the indoor environment temperature and the target setting temperature.

[0055] In the embodiment, the application provides a technical means for determining the wind speed of the outer fan according to the relationship between the temperature variation degree of the indoor environment temperature and the preset value, and the preset relationship between the indoor environment temperature and the target setting temperature. When the mobile air conditioner detects that the difference between the indoor environment temperature and the target setting temperature is less than or equal to a first preset value, the wind speed of the outer fan is adjusted according to the preset relationship; when the mobile air conditioner detects that the difference between the indoor environment temperature and the target setting temperature is greater than the first preset value for two consecutive times, the wind speed of the outer fan is adjusted according to the relationship between the temperature variation degree of the indoor environment temperature and the preset value; wherein the first preset value is 0.

[0056] Through the control method of the embodiment, the application can accurately adjust the wind speed of the fixed-frequency mobile air conditioner according to the relationship between the temperature variation degree of the indoor environment temperature and the preset value and the preset relationship between the indoor environment temperature and the target set temperature, keep the wind speed of the mobile air conditioner at the most appropriate wind speed level, and thus improve the user experience.

[0057] In some embodiments of the application, the wind speed of the outer fan is determined according to the indoor environment temperature, including: an initial wind speed setting step of determining the initial wind speed of the outer fan according to the indoor environment temperature and the target set temperature; and a wind speed adjustment step of adjusting the wind speed of the outer fan according to the temperature variation degree of the indoor environment temperature.

[0058] In the embodiment, the control method of the mobile air conditioner of the application includes an initial wind speed setting step and a wind speed adjustment step. When the mobile air conditioner is just started, the mobile air conditioner adjusts the wind speed of the outer fan according to the initial wind speed setting step; when the initial wind speed setting step is completed, the mobile air conditioner adjusts the wind speed of the outer fan according to the wind speed adjustment step after waiting for a second preset time length. The second preset time length is 3-5 minutes, which can be determined according to actual conditions.

[0059] In the initial wind speed setting step, the mobile air conditioner adjusts the wind speed of the outer fan according to the relationship between the difference between the indoor environment temperature and the target set temperature and the preset temperature; and adjusts the wind speed of the outer fan to a preset wind speed level according to different relationships between the difference between the indoor environment temperature and the target set temperature and the preset temperature; wherein the wind speed level includes a first wind speed, a second wind speed, a third wind speed, and a fourth wind speed; and the first wind speed < the second wind speed < the third wind speed < the fourth wind speed.

[0060] In the wind speed adjustment step, the mobile air conditioner adjusts the wind speed of the outer fan according to the relationship between the temperature variation degree of the indoor environment temperature and the preset temperature; and adjusts the wind speed of the outer fan to a preset wind speed level according to different relationships between the temperature variation degree of the indoor environment temperature and the preset temperature; wherein the wind speed level includes a second wind speed, a third wind speed, and a fourth wind speed; and the second wind speed < the third wind speed < the fourth wind speed.

[0061] In the wind speed adjustment step, when switching between the wind speed levels of the outer fan, a first preset time length is required to prevent the wind speed level from frequently jumping. The first preset time length is 20s, which can be adjusted according to actual needs.

[0062] Through the control method of the embodiment, the application proposes a technical means of adjusting the wind speed of the outer fan according to the initial wind speed setting step and the wind speed adjustment step, which can accurately control the wind speed of the outer fan, keep the wind speed of the mobile air conditioner at the most appropriate wind speed level, and thus improve the user experience.

[0063] In some embodiments of the present application, the determination of the wind speed of the external fan according to the indoor environment temperature comprises: an initial wind speed setting step of determining the initial wind speed of the external fan according to the indoor environment temperature and the target set temperature; or a wind speed adjustment step of adjusting the wind speed of the external fan according to the temperature variation degree of the indoor environment temperature.

[0064] In the present embodiment, when the variation degree of the indoor environment temperature is large during the operation of the mobile air conditioner, the mobile air conditioner will execute the initial wind speed setting step or the wind speed adjustment step according to the actual situation.

[0065] For example, when the mobile air conditioner executes the initial wind speed setting step and the difference between the real-time detected indoor environment temperature and the target set temperature is less than the first preset value, the wind speed of the external fan is adjusted according to the preset relationship when the difference between the indoor environment temperature and the target set temperature is less than the first preset value. The means for adjusting the wind speed of the external fan include adjusting the wind speed of the external fan to the first level, stopping the external fan, restarting the external fan and adjusting the wind speed level to the third level. Then the initial wind speed setting step is executed again.

[0066] During the execution of the wind speed adjustment step by the mobile air conditioner, when the target set temperature changes, the wind speed of the external fan remains the current wind speed level, and then the initial wind speed setting step is executed. When the target set temperature does not change, the wind speed adjustment step is continuously executed.

[0067] Through the control method of the present embodiment, the present application proposes the technical means for adjusting the wind speed of the external fan according to the initial wind speed setting step or the wind speed adjustment step, which can accurately control the wind speed of the external fan, keep the wind speed of the mobile air conditioner at the most appropriate wind speed level, and thus improve the user experience.

[0068] In some embodiments of the present application, the wind speed adjustment step comprises the following steps: Figure 2

[0069] Step S11: After entering the wind speed adjustment step, the first difference value is obtained according to the difference between the last obtained indoor environment temperature and the target set temperature.

[0070] Step S13: The second difference value is obtained according to the difference between the present obtained indoor environment temperature and the target set temperature.

[0071] Step S14: The wind speed of the external fan is determined according to the difference between the first difference value and the second difference value.

[0072] ​In the embodiment, when the mobile air conditioner performs the wind speed adjustment step, the indoor environment temperature and the target set temperature are obtained at the last time, and the difference between the indoor environment temperature and the target set temperature is calculated to obtain a first difference. When the first difference is greater than a first preset value, the current indoor environment temperature and the target set temperature are obtained after an interval sampling period, and the difference between the indoor environment temperature and the target set temperature is calculated to obtain a second difference. When the second difference is greater than the first preset value, the difference between the first difference and the second difference is calculated, and the speed of the outer fan is adjusted according to the relationship between the difference and a preset temperature.

[0073] By the control method of the embodiment, in the wind speed adjustment step, the difference between the difference between the indoor environment temperature and the target set temperature obtained at the last two times and the preset temperature is used to adjust the speed of the outer fan, so that the speed of the outer fan can be accurately controlled, the wind speed of the mobile air conditioner is kept at the most suitable wind speed level, and the user experience is improved.

[0074] In some embodiments of the application, with reference to Figure 3 , the wind speed adjustment step comprises the following steps:

[0075] Step S12: After entering the wind speed adjustment step, the first difference is obtained according to the difference between the indoor environment temperature and the target set temperature obtained at the first time.

[0076] Step S13: The second difference is obtained according to the difference between the indoor environment temperature and the target set temperature obtained at the current time.

[0077] Step S14: The speed of the outer fan is determined according to the difference between the first difference and the second difference.

[0078] In the embodiment, when the mobile air conditioner performs the wind speed adjustment step, the indoor environment temperature and the target set temperature are obtained at the first time, and the difference between the indoor environment temperature and the target set temperature is calculated to obtain a first difference, and the first difference is greater than a first preset value. In the case where the target set temperature is unchanged, the current indoor environment temperature is obtained after an interval sampling period, and the difference between the indoor environment temperature and the target set temperature is calculated to obtain a second difference. When the second difference is greater than the first preset value, the difference between the first difference and the second difference is calculated, and the speed of the outer fan is adjusted according to the relationship between the difference and a preset temperature. The first preset value is 0.

[0079] By the control method of the embodiment, in the wind speed adjustment step, the difference between the difference between the indoor environment temperature and the target set temperature obtained at intervals of several sampling periods and the preset temperature is used to adjust the wind speed of the outdoor fan, so that the wind speed of the outdoor fan can be accurately controlled, the wind speed of the outdoor fan of the mobile air conditioner is kept at the most appropriate wind speed level, and the user experience is improved.

[0080] In some embodiments of the application, with reference to Figure 4 , the wind speed of the outdoor fan is determined according to the difference between the first difference and the second difference, including the following steps:

[0081] Step S22: When the difference between the first difference and the second difference is greater than or equal to the third preset temperature, the wind speed is adjusted to the second wind speed.

[0082] Step S23: When the difference between the first difference and the second difference is greater than or equal to the fourth preset temperature and less than the third preset temperature, the wind speed is adjusted to the third wind speed.

[0083] Step S24: When the difference between the first difference and the second difference is less than the fourth preset temperature, the wind speed is adjusted to the fourth wind speed.

[0084] In this embodiment, the second wind speed is less than the third wind speed, and the third wind speed is less than the fourth wind speed; the third preset temperature is greater than the fourth preset temperature. The third preset temperature and the fourth preset temperature can be determined according to actual conditions. When the wind speed level of the outdoor fan is switched, the first preset time interval is required to prevent the wind speed level from jumping frequently, and the first preset time interval is 20s, which can be adjusted according to actual needs.

[0085] By the control method of the embodiment, in the wind speed adjustment step, the difference between the first difference and the second difference and the preset temperature is used to adjust the wind speed of the outdoor fan, which can accurately control the wind speed of the outdoor fan according to the current actual situation, keep the wind speed of the mobile air conditioner at the most appropriate wind speed level, and improve the user experience.

[0086] In some embodiments of the application, the control method further includes: determining whether the target set temperature changes, and if it changes, entering the initial wind speed setting step.

[0087] In this embodiment, when the target set temperature of the mobile air conditioner changes, the mobile air conditioner no longer continues to execute the wind speed adjustment step, but executes the initial wind speed setting step to adjust the wind speed of the outdoor fan.

[0088] By the control method of the embodiment, when the target set temperature of the mobile air conditioner changes, adjusting the wind speed of the outer fan based on the adjusted target set temperature in the wind speed adjustment step can make the user be in a colder or hotter indoor environment, thereby affecting the user experience. By performing the initial wind speed adjustment step, the mobile air conditioner can adjust the rotation speed of the outer fan according to the relationship between the indoor environment temperature, the target set temperature and the preset temperature, so that the wind speed of the mobile air conditioner can be kept at the most appropriate wind speed level, thereby improving the user experience.

[0089] In some embodiments of the application, the control method further comprises: when the target set temperature is set for the first time after the mobile air conditioner is started, starting the outer fan at the starting wind speed and entering the initial wind speed setting step.

[0090] In this embodiment, when the mobile air conditioner is started, the outer fan is started at the starting wind speed, and at the same time, the initial wind speed setting step is entered. After the wind speed of the outer fan reaches the starting wind speed and waits for the first time length, the wind speed level of the outer fan is adjusted according to the preset relationship between the indoor environment temperature and the target set temperature obtained when the mobile air conditioner is started.

[0091] Preferably, the first time length is 1 minute, and the starting wind speed can be the third wind speed or the second wind speed, which is set according to the actual situation.

[0092] By the control method of the embodiment, when the mobile air conditioner is started, and after the outer fan is started, if the wind speed of the outer fan does not reach the starting wind speed, the wind speed level of the outer fan is not changed; after the wind speed of the outer fan reaches the starting wind speed and waits for the first time length, the wind speed of the outer fan is adjusted according to the judgment result in the initial wind speed setting step.

[0093] In some embodiments of the application, the initial wind speed setting step comprises the following steps: Figure 5

[0094] Step S31: When the difference between the indoor environment temperature and the target set temperature is greater than or equal to the first preset temperature, the initial wind speed of the outer fan is determined to be the fourth wind speed.

[0095] Step S32: When the difference between the indoor environment temperature and the target set temperature is greater than or equal to the second preset temperature and less than the first preset temperature, the initial wind speed of the outer fan is determined to be the third wind speed.

[0096] Step S33: When the difference between the indoor environment temperature and the target set temperature is greater than the fifth preset temperature and less than the second preset temperature, the initial wind speed of the outer fan is determined to be the second wind speed.

[0097] Step S34: When the difference between the indoor environment temperature and the target set temperature is less than or equal to the fifth preset temperature, the outer fan is determined to be stopped.​

[0098] In the embodiment, the first preset temperature is greater than the second preset temperature, and the second preset temperature is greater than the fifth preset temperature; the fourth wind speed is greater than the third wind speed, and the third wind speed is greater than the second wind speed.

[0099] Preferably, the first time length is 1 minute, and the second time length is 30 seconds.

[0100] In the initial wind speed setting step, when it is necessary to adjust the wind speed level of the outdoor fan, the first time length is waited, and then the wind speed of the outdoor fan is adjusted to the corresponding wind speed level.

[0101] In step S34, when the difference between the indoor environment temperature and the target set temperature is less than or equal to the fifth preset temperature, the first time length is waited, the wind speed of the outdoor fan is adjusted to the first wind speed, and then the second time length is waited, and the outdoor fan is adjusted to stop.

[0102] Through the control method of the embodiment, the initial wind speed setting step adjusts the wind speed of the outdoor fan to different wind speed levels according to different relationships between the difference between the indoor environment temperature and the target set temperature and the preset temperature, so as to accurately control the wind speed of the outdoor fan, keep the wind speed of the mobile air conditioner at the most appropriate wind speed level, and thus improve the user experience.

[0103] In some embodiments of the application, the wind speed adjusting step further comprises: if the difference between the indoor environment temperature and the target set temperature is less than or equal to the first preset value, controlling the wind speed of the outdoor fan according to a preset strategy, and obtaining the indoor environment temperature; when the difference between the indoor environment temperature and the target set temperature is greater than the first preset value for a continuous preset number of times, entering the initial wind speed setting step.

[0104] Preferably, the first preset value is 0, and the preset number of times is 10.

[0105] In the embodiment, when the difference between the indoor environment temperature and the target set temperature is less than or equal to the first preset value during the execution of the wind speed adjusting step of the mobile air conditioner, the mobile air conditioner does not continue to perform the judgment between the difference between the difference between the indoor environment temperature and the target set temperature and the preset temperature.

[0106] Instead, the wind speed of the outdoor fan is controlled according to a preset strategy, which comprises: the outdoor fan continues to execute for the first time length at the current wind speed level, then the wind speed of the outdoor fan is adjusted to the first wind speed, and after the second time length, if the difference between the detected indoor environment temperature and the target set temperature is still less than or equal to the first preset value, the outdoor fan is stopped.

[0107] Preferably, the first time length is 1 minute, the second time length is 30 seconds, and the sampling period can be set according to actual conditions.

[0108] Every other sampling period, the indoor environment temperature and the target set temperature are acquired, and the difference between the indoor environment temperature and the target set temperature is calculated and stored. Whether the difference between the indoor environment temperature and the target set temperature is greater than the first preset value or not, the difference is stored. When the continuously stored differences are all greater than the first preset value and the continuous number of times reaches a preset number of times, the mobile air conditioner performs the initial wind speed setting step.

[0109] By the control method of the embodiment, the present application adopts the processing method when the difference between the indoor environment temperature and the target set temperature is less than or equal to the first preset value, so as to accurately control the wind speed of the outer fan, keep the wind speed of the mobile air conditioner at the most appropriate wind speed level, and further improve the user experience.

[0110] In some embodiments of the present application, the control method further comprises: when the preset condition triggers the outer fan to stop, controlling the outer fan according to a corresponding preset control strategy.

[0111] Further, in some embodiments of the present application, the preset condition is that the compressor is turned off, and the preset control strategy is: first adjusting the wind speed of the outer fan to the first level, and then adjusting the outer fan to stop; the preset condition is that the mobile air conditioner is detected to have a fault, and the preset control strategy is: adjusting and locking the wind speed to the second level.

[0112] In the embodiment, the preset condition is that the compressor is turned off, and first adjusting the wind speed of the outer fan to the first level, and then adjusting the outer fan to stop after waiting for a second time length, and the second time length is 30 seconds.

[0113] The preset condition is that the mobile air conditioner is detected to have a fault, and the wind speed of the outer fan is adjusted and locked to the second level in the case that the compressor is turned on. When the compressor is turned off, the wind speed locking of the outer fan is exited; or when the fault of the mobile air conditioner is cleared, the wind speed locking of the outer fan is exited; or when the mobile air conditioner is turned off, the wind speed locking of the outer fan is exited.

[0114] By the control method of the embodiment, the present application adopts the technical means of adjusting the wind speed of the outer fan when the compressor is turned off or the mobile air conditioner has a fault, to avoid that the outer fan is in a high wind speed level and causes other faults, or even causes the mobile air conditioner to be damaged, and to improve the safety of the mobile air conditioner.
