Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
Hereinafter, a portable air conditioner, a control method, an apparatus thereof, and a storage medium according to embodiments of the present invention will be described with reference to the accompanying drawings.
In one embodiment of the present invention, the portable air conditioner includes a compressor, a first fan for providing service to a user, and a second fan for providing service to the compressor. The first fan directly blows to the user. The second fan serves the compressor, for example, cools the compressor.
Fig. 1 is a flowchart of a control method of a portable air conditioner according to an embodiment of the present invention.
As shown in fig. 1, the control method of the portable air conditioner includes the steps of:
s11, determining the operation gear information of the portable air conditioner.
Specifically, the user may issue an instruction to the portable air conditioner, the portable air conditioner obtains the instruction, and determines operation gear information of the portable air conditioner according to the instruction, where the operation gear information includes a target gear desired by the user. For example, a plurality of gear buttons can be preset on the portable air conditioner, each gear button corresponds to one operation gear, and then the portable air conditioner can determine operation gear information through the condition of the gear button; or, a touch panel can be arranged on the portable air conditioner, so that a user can select an operation gear on the touch panel, and the portable air conditioner can determine operation gear information according to the operation gear selected by the user; or the user can also issue an instruction to the portable air conditioner through a preset APP on the mobile terminal, the portable air conditioner obtains the instruction, and the operation gear information of the portable air conditioner is determined according to the instruction.
The operating gear information comprises a plurality of operating gears, each operating gear corresponds to a second fan target rotating speed, a first fan target rotating speed and a compressor target operating frequency, and the operating gears are in positive correlation with the second fan target rotating speed, the first fan target rotating speed and the compressor target operating rotating speed.
The target operation frequency of the compressor is a preset frequency. However, if there is a case such as current limiting or temperature limiting, the frequency limiting frequency may be set as the compressor target operation frequency. For example, if the preset target operating frequency of the compressor exceeds the safe operating frequency of the portable air conditioner, the safe operating frequency is taken as the target operating frequency of the compressor; the safe operating frequency may be, for example, an upper limit operating frequency that does not overheat the compressor or an upper limit operating frequency that does not cause excessive current to occur inside the portable air conditioner.
As an example, if the operation range information of the portable air conditioner includes four operation ranges: the portable air conditioner comprises a first operation gear, a second operation gear, a third operation gear and a fourth operation gear, wherein the operation capacity of the portable air conditioner under the first operation gear, the second operation gear, the third operation gear and the fourth operation gear is as follows: operating gear one > operating gear two > operating gear three > operating gear four. If the target operating frequencies of the compressors corresponding to the first operating gear, the second operating gear, the third operating gear and the fourth operating gear are the first operating frequency of the compressor, the second operating frequency of the compressor, the third operating frequency of the compressor and the fourth operating frequency of the compressor respectively, the magnitude relation of the first operating frequency of the compressor, the second operating frequency of the compressor, the third operating frequency of the compressor and the fourth operating frequency of the compressor is that the first operating frequency of the compressor is greater than the second operating frequency of the compressor, the third operating frequency of the compressor is greater than the fourth operating frequency of the compressor; if the first fan target rotating speed corresponding to the first operation gear, the second operation gear, the third operation gear and the fourth operation gear is the first fan target rotating speed, the second fan target rotating speed, the third fan target rotating speed and the fourth fan target rotating speed respectively, the magnitude relation of the first fan target rotating speed, the second fan target rotating speed, the third fan target rotating speed and the fourth fan target rotating speed is that the first fan target rotating speed is greater than the second fan target rotating speed, the third fan target rotating speed is greater than the fourth fan target rotating speed; if the second fan target rotation speeds corresponding to the first operation gear, the second operation gear, the third operation gear and the fourth operation gear are respectively the fan target rotation speed five, the fan target rotation speed six, the fan target rotation speed seven and the fan target rotation speed eight, the magnitude relation of the fan target rotation speed five, the fan target rotation speed six, the fan target rotation speed seven and the fan target rotation speed eight is that the fan target rotation speed five, the fan target rotation speed six, the fan target rotation speed seven and the fan target rotation speed eight.
The operation gear information of the portable air conditioner can be preset gear information or gear information set by a user. For example, when the portable air conditioner is produced by a merchant, the operation capability of the common air conditioner can be determined in a mode such as big data analysis, and then the second fan target rotating speed, the compressor target operating frequency and the first fan target rotating speed are determined according to the common operation capability of the air conditioner, so that gear information is determined according to the information. The portable air conditioner can be further provided with a touch panel, so that a user can set the operation capacity corresponding to a certain gear by the touch panel by himself, and the portable air conditioner can determine the second fan target rotating speed, the compressor target operating frequency and the first fan target rotating speed corresponding to the gear according to the operation capacity set by the user by himself.
Or, a communication module can be arranged on the portable air conditioner, so that the portable air conditioner can communicate with a local weather station according to the communication module, and gear information can be set according to a communication result. For example, if the portable air conditioner communicates with the local weather station through the communication module thereon, and determines that the current season is spring, the portable air conditioner may set the second fan target rotation speed, the compressor target operation frequency and the first fan target rotation speed corresponding to spring, so as to determine gear information corresponding to spring according to the information; if the portable air conditioner is communicated with the local weather table through the communication module on the portable air conditioner, and the current season is summer, the portable air conditioner can set a second fan target rotating speed, a compressor target operating frequency and a first fan target rotating speed corresponding to summer, so that gear information corresponding to summer is determined according to the information; if the portable air conditioner is communicated with the local weather table through the communication module on the portable air conditioner, and the current season is autumn, the portable air conditioner can set a second fan target rotating speed, a compressor target operating frequency and a first fan target rotating speed corresponding to autumn, so that gear information corresponding to autumn is determined according to the information; if the portable air conditioner is communicated with the local weather table through the communication module on the portable air conditioner, and the current season is determined to be winter, the portable air conditioner can set the second fan target rotating speed, the compressor target operating frequency and the first fan target rotating speed corresponding to winter, so that gear information corresponding to winter is determined according to the information. Further, the communication module can also communicate with the weather table, so that the temperature information of the current day is obtained, and the gear information corresponding to the current season is adjusted according to the temperature information of the current day and the average temperature of the current season; for example, if the temperature on the day is determined to be less than the average temperature in the current season, the second fan target rotation speed, the compressor target operation frequency and the first fan target rotation speed corresponding to the gear information are adjusted downwards by a first value, if the temperature on the day is determined to be greater than the average temperature in the current season, the second fan target rotation speed, the compressor target operation frequency and the first fan target rotation speed corresponding to the gear information are adjusted upwards by a second value, and the first data and the second value can be adjusted according to the difference value between the temperature on the day and the average temperature in the current season. Further, a sensor can be arranged on the portable air conditioner, so that the ambient temperature around the portable air conditioner is obtained through the sensor, and the gear information is adjusted according to the relation between the ambient temperature around the portable air conditioner and a preset temperature threshold; for example, if it is determined that the ambient temperature around the portable air conditioner is less than the preset temperature threshold, the second fan target rotation speed, the compressor target operation frequency and the first fan target rotation speed corresponding to the gear information are adjusted downward by a third value, if it is determined that the ambient temperature around the portable air conditioner is greater than the preset temperature threshold, the portable air conditioner is adjusted upward by a fourth value with the gear information, and the third value and the fourth value can be adjusted according to a difference between the ambient temperature around the portable air conditioner and the preset temperature threshold. Therefore, the automatic setting and adjustment of the gear information according to the environment parameters can be realized.
S12, determining a target operating frequency of the compressor, a target rotating speed of the first fan and a target rotating speed of the second fan according to the operating gear information.
Specifically, after the operation gear information is obtained, a target gear desired by the user may be determined according to the operation gear information, so as to obtain a second fan target rotation speed, a compressor target operation frequency and a first fan target rotation speed corresponding to the target gear.
As an example, if the portable air conditioner has a first operating gear, a second operating gear, a third operating gear and a fourth operating gear; the target operating frequencies of the compressors corresponding to the first operating gear, the second operating gear, the third operating gear and the fourth operating gear are respectively the first operating frequency of the compressor, the second operating frequency of the compressor, the third operating frequency of the compressor and the fourth operating frequency of the compressor, and the magnitude relation of the first operating frequency of the compressor, the second operating frequency of the compressor, the third operating frequency of the compressor and the fourth operating frequency of the compressor is that the first operating frequency of the compressor is greater than the second operating frequency of the compressor, the third operating frequency of the compressor is greater than the fourth operating frequency of the compressor; the first fan target gear corresponding to the first operation gear, the second operation gear, the third operation gear and the fourth operation gear is respectively a first fan target rotating speed, a second fan target rotating speed, a third fan target rotating speed and a fourth fan target rotating speed, and the first fan target rotating speed is greater than the second fan target rotating speed, the third fan target rotating speed is greater than the fourth fan target rotating speed; the second fan target rotating speeds corresponding to the first operation gear, the second operation gear, the third operation gear and the fourth operation gear are respectively a fan target rotating speed five, a fan target rotating speed six, a fan target rotating speed seven and a fan target rotating speed eight, and the magnitude relation of the fan target rotating speed five, the fan target rotating speed six, the fan target rotating speed seven and the fan target rotating speed eight is that the fan target rotating speed five, the fan target rotating speed six, the fan target rotating speed seven and the fan target rotating speed eight. After the operation gear information is acquired, if the target gear expected by the user is judged to be the operation gear I according to the operation gear information, determining that the second fan target rotating speed, the compressor target operating frequency and the first fan target rotating speed corresponding to the target gear are respectively the fan target rotating speed five, the compressor operating frequency I and the fan target rotating speed I; if the target gear expected by the user is judged to be the second running gear according to the running gear information, determining that the second fan target rotating speed, the compressor target operating frequency and the first fan target rotating speed which correspond to the target gear are respectively the sixth fan target rotating speed, the second compressor operating frequency and the second fan target rotating speed; if the target gear expected by the user is judged to be the third running gear according to the running gear information, determining that the second fan target rotating speed, the compressor target operating frequency and the first fan target rotating speed corresponding to the target gear are respectively the seventh fan target rotating speed, the third compressor operating frequency and the third fan target rotating speed; if the target gear expected by the user is judged to be the fourth running gear according to the running gear information, the second fan target rotating speed, the compressor target operating frequency and the first fan target rotating speed corresponding to the target gear are determined to be the eighth fan target rotating speed, the fourth compressor operating frequency and the fourth fan target rotating speed respectively.
S13, controlling the compressor, the first fan and the second fan according to the target running frequency of the compressor, the target rotating speed of the first fan and the target rotating speed of the second fan.
In one embodiment of the present invention, as shown in fig. 2, the determining the target operating frequency of the compressor, the target rotational speed of the first fan, and the target rotational speed of the second fan according to the operating gear information includes:
s21, determining a target operating frequency of the compressor and a target rotating speed of the first fan according to the operating gear information, and determining a gear adjusting direction of the portable air conditioner.
It should be noted that, since the compressor cannot directly change its operating frequency to the target operating frequency of the compressor, when the portable air conditioner is downshifted, a certain time is required to reduce the operating frequency of the compressor to the target operating frequency of the compressor, and at this time, if the rotational speed of the second fan is directly adjusted to the target rotational speed of the second fan, the compressor will fail; for example, if the second fan is a fan for providing cooling service for the compressor, the cooling problem of the portable air conditioner to the compressor may occur because the rotation speed of the second fan has been reduced to the second fan target rotation speed in the process of reducing the operation frequency of the compressor to the compressor target frequency. Therefore, the target operating frequency of the compressor and the target rotating speed of the first fan can be determined according to the operating gear information, and the gear adjusting direction of the portable air conditioner is determined, so that the operating frequency of the compressor is directly adjusted to the target operating frequency of the compressor, and the rotating speed of the first fan is directly adjusted to the target rotating speed of the first fan; and simultaneously, the rotating speed of the second fan is adjusted according to the gear adjusting direction.
Specifically, a target gear desired by a user is determined according to the operation gear information, so that the target operation frequency of the compressor and the target rotation speed of the first fan corresponding to the target gear are obtained, and meanwhile, the current gear of the portable air conditioner is obtained, and further, the gear adjusting direction of the portable air conditioner is determined according to the current gear of the portable air conditioner and the target gear desired by the user. Thus, it is possible to determine the target operating frequency of the compressor and the target rotational speed of the first fan corresponding to the target gear desired by the user, and to determine the gear adjustment direction.
Optionally, the target gear desired by the user can be determined according to the running gear information, and the target gear information corresponding to the target gear is obtained according to the target gear desired by the user, wherein the target gear information comprises the target running frequency of the compressor and the target rotating speed of the first fan; further obtaining at least one of the current compressor running frequency of the portable air conditioner and the fan target rotating speed of the first fan; and comparing the acquired result with corresponding target gear information, and determining the gear adjusting direction according to the comparison result.
Further, after the first fan target rotation speed, the compressor target operation frequency and the gear adjusting direction are determined, the compressor operation frequency of the portable air conditioner is adjusted to the compressor target operation frequency, and the rotation speed of the first fan is adjusted to the first fan target rotation speed.
S22, determining a second fan target rotating speed according to the gear adjusting direction of the portable air conditioner.
In one embodiment of the present invention, as shown in fig. 3, the determining the second fan target rotation speed according to the gear adjustment direction of the portable air conditioner includes:
s31, when the gear adjusting direction of the portable air conditioner is from a low gear to a high gear, determining a second fan target rotating speed according to the operation gear information.
S32, when the gear adjusting direction of the portable air conditioner is from a high gear to a low gear, the compressor is subjected to frequency reduction control, and when the running frequency of the compressor is reduced to a target gear corresponding to the running gear information, the target rotating speed of the second fan is determined according to the target gear.
Step S32 will be described in detail with reference to a specific example.
In this specific example, the above-described operating range information includes a low range, a high range, a strong range, a medium range. In this specific example, the strong gear is the first operating gear, the high gear is the second operating gear, the middle gear is the third operating gear, the low gear is the fourth operating gear, the target frequency is the target operating frequency of the compressor, the second rotating speed is the target rotating speed of the second fan, and the current frequency is the operating frequency of the compressor.
When the portable air conditioner is switched from the first operation gear to the second operation gear, if the current frequency is greater than the target frequency corresponding to the second operation gear, controlling the second fan to keep the second rotating speed corresponding to the first operation gear; and if the current frequency is smaller than or equal to the target frequency corresponding to the second operating gear, controlling the second fan to operate at a second rotating speed corresponding to the second operating gear.
Specifically, when the portable air conditioner is switched from the first operation gear to the second operation gear, the portable air conditioner detects the current frequency in a preset time period or monitors the current frequency in real time; because the current frequency gradually decreases from the target frequency corresponding to the first operating gear to the target frequency corresponding to the second operating gear in the process of switching the portable air conditioner from the first operating gear to the second operating gear; thus, the second fan continues to operate at the second rotational speed corresponding to the first operating gear before the current frequency is detected to decrease to the target frequency corresponding to the second operating gear, and the second fan operates at the second rotational speed corresponding to the second operating gear after the current frequency is detected to decrease to the target frequency corresponding to the second operating gear.
When the portable air conditioner is switched from the second operation gear to the third operation gear, if the current frequency is greater than the target frequency corresponding to the second operation gear, controlling the second fan to operate at a second rotating speed corresponding to the first operation gear; if the current frequency is smaller than or equal to the target frequency corresponding to the second operating gear and larger than the target frequency corresponding to the third operating gear, controlling the second fan to keep the second rotating speed corresponding to the second operating gear to operate; and if the current frequency is smaller than or equal to the target frequency corresponding to the third operating gear, controlling the second fan to operate at a second rotating speed corresponding to the third operating gear.
Specifically, when the portable air conditioner is switched from the second operation gear to the third operation gear, the portable air conditioner detects the current frequency in a preset time period or monitors the current frequency in real time. In the process of switching the portable air conditioner to the third operating gear, the current frequency gradually decreases to the target frequency corresponding to the third operating gear, so that the current frequency is firstly judged, if the current frequency is larger than the target frequency corresponding to the second operating gear, the current operating gear of the portable air conditioner is the first operating gear, and therefore, the second fan continues to operate at the second rotating speed corresponding to the first operating gear before the current frequency is detected to decrease to the target frequency corresponding to the second operating gear, and the second fan operates at the second rotating speed corresponding to the second operating gear after the current frequency is detected to decrease to the target frequency corresponding to the second operating gear. Further, the current frequency is continuously detected, the second fan continues to operate at the second rotating speed corresponding to the second operating gear before the current frequency is detected to be reduced to the target frequency corresponding to the third operating gear, and the second fan operates at the second rotating speed corresponding to the third operating gear after the current frequency is detected to be reduced to the target frequency corresponding to the third operating gear.
Or if the obtained current frequency is less than or equal to the target frequency corresponding to the second operating gear and greater than the target frequency corresponding to the third operating gear, the current operating gear of the portable air conditioner is the second operating gear, so that the second fan continues to operate at the second rotating speed corresponding to the second operating gear before the current frequency is detected to be reduced to the target frequency corresponding to the third operating gear, and the second fan operates at the second rotating speed corresponding to the third operating gear after the current frequency is detected to be reduced to the target frequency corresponding to the third operating gear.
When the portable air conditioner is switched from the third operation gear to the fourth operation gear, if the current frequency is greater than the target frequency corresponding to the second operation gear, controlling the second fan to operate at a second rotating speed corresponding to the first operation gear; if the current frequency is smaller than or equal to the target frequency corresponding to the second operating gear and larger than the target frequency corresponding to the third operating gear, controlling the second fan to operate at a second rotating speed corresponding to the second operating gear; if the current frequency is smaller than or equal to the target frequency corresponding to the third operating gear and larger than the target frequency corresponding to the fourth operating gear, controlling the second fan to keep the second rotating speed corresponding to the third operating gear to operate; and if the current frequency is smaller than or equal to the target frequency corresponding to the fourth operating gear, controlling the second fan to operate at a second rotating speed corresponding to the fourth operating gear.
Specifically, when the portable air conditioner is switched from the third operating gear to the fourth operating gear, the portable air conditioner detects the current frequency in a preset time period or monitors the current frequency in real time. In the process of switching the portable air conditioner to the fourth operating gear, the current frequency gradually decreases to the target frequency corresponding to the third operating gear, so that the current frequency is firstly judged, if the current frequency is larger than the target frequency corresponding to the second operating gear, the current operating gear of the portable air conditioner is the first operating gear, and therefore the second fan continues to operate at the second rotating speed corresponding to the first operating gear before the current frequency is detected to decrease to the target frequency corresponding to the second operating gear, and the second fan operates at the second rotating speed corresponding to the second operating gear after the current frequency is detected to decrease to the target frequency corresponding to the second operating gear. Further, the current frequency is continuously detected, the second fan continues to operate at the second rotating speed corresponding to the second operating gear before the current frequency is detected to be reduced to the target frequency corresponding to the third operating gear, and the second fan operates at the second rotating speed corresponding to the third operating gear after the current frequency is detected to be reduced to the target frequency corresponding to the third operating gear. Further, the current frequency is continuously detected, the second fan continues to operate at the second rotating speed corresponding to the middle wind gear before the current frequency is detected to be reduced to the target frequency corresponding to the fourth operating gear, and the second fan operates at the second rotating speed corresponding to the fourth operating gear after the current frequency is detected to be reduced to the target frequency corresponding to the fourth operating gear.
Or if the current frequency is judged to be smaller than or equal to the target frequency corresponding to the second operating gear and larger than the target frequency corresponding to the third operating gear, the current operating gear of the portable air conditioner is the second operating gear, so that the second fan continues to operate at the second rotating speed corresponding to the second operating gear before the current frequency is detected to be reduced to the target frequency corresponding to the third operating gear, and the second fan operates at the second rotating speed corresponding to the third operating gear after the current frequency is detected to be reduced to the target frequency corresponding to the third operating gear.

Specifically, if the instruction issued by the user is an instruction for closing the portable air conditioner, the main control module stores the gear information of the current portable air conditioner and controls the first fan to stop working after a first preset time, and meanwhile controls the compressor to gradually reduce the running frequency to zero at a preset rate. A patch temperature sensor can be arranged on the portable air conditioner, the temperature of the compressor is monitored in real time according to the patch temperature sensor, and the second fan is turned off after the temperature of the compressor is monitored to be smaller than or equal to the temperature threshold of the compressor. The compressor temperature threshold may be set according to an average temperature in a current season and a temperature of a current day.
If the instruction issued by the user is an instruction for starting the portable air conditioner, the main control module acquires the gear information stored in the main control module and deletes the information from the memory. And further controlling the portable air conditioner to work according to the gear information.
If the instruction issued by the user is an instruction including running gear information, the main control module controls the second fan, the first fan and the compressor according to the instruction of the user according to the following table 1. Namely, the running gear information is acquired according to the instruction of the user, the target gear desired by the user is acquired according to the running gear information, and then the second fan, the first fan and the compressor are controlled according to the target gear desired by the user.
TABLE 1
| Gear position | Compressor target operating frequency | Target rotation speed of first fan | Target rotation speed of second fan |
| Strong gear | Compressor operating frequency one | Fan target rotation speed one | Target rotating speed five of fan |
| High wind shield | Compressor operating frequency two | Fan target rotation speed II | Target rotating speed six of fan |
| Middle wind shield | Compressor operating frequency three | Target rotation speed three of fan | Target rotation speed seven of fan |
| Low wind shield | Compressor operating frequency four | Target rotation speed of fan four | Fan targetEight rotational speeds |
Wherein, the first compressor operation frequency is greater than the second compressor operation frequency, the third compressor operation frequency is greater than the fourth compressor operation frequency, the first fan target rotating speed is greater than the second fan target rotating speed, the third fan target rotating speed is greater than the fourth fan target rotating speed, the fifth fan target rotating speed is greater than the sixth fan target rotating speed, and the seventh fan target rotating speed is greater than the eighth fan target rotating speed.
Alternatively, if current frequency limiting or temperature frequency limiting or the like occurs, the compressor is operated according to the frequency-limited compressor operating frequency.
It should be noted that, because the speed of the compressor in the frequency raising and lowering is slower and the speed of the fan is faster, the first fan directly blows to the user, the response condition of the first fan affects the use experience of the user, the second fan affects the stability of the operation of the compressor, and the adjustment process of the second fan needs to be matched with the frequency raising and lowering process of the compressor. Therefore, the main control module determines the target operating frequency of the compressor and the target rotating speed of the first fan according to the operating gear information from the man-machine interface, and accordingly controls the operation of the compressor and the first fan. Meanwhile, whether the current adjustment is from a low gear to a high gear or from a high gear to a low gear is judged, and if the current adjustment is from the low gear to the high gear, the second fan is directly controlled according to the target rotating speed of the second fan; if the gear is adjusted from the high gear to the low gear, the second fan is controlled according to fig. 5. Therefore, the first fan can quickly respond, the use experience of a user is improved, the second fan is matched with the compressor, and the reliability of the portable air conditioner is guaranteed.
In summary, according to the control method of the portable air conditioner, when a user wants to perform frequency-raising operation on the portable air conditioner, the first fan, the second fan and the compressor are controlled to directly respond to the instruction of the user; when a user wants to perform the frequency-reducing operation on the portable air conditioner, the first fan and the compressor are controlled to directly respond to the instruction of the user, and the second fan is controlled to respond to the instruction of the user in cooperation with the compressor. Therefore, the portable air conditioner can be simply and effectively controlled, and the reliability of the portable air conditioner is ensured.
