In one aspect, the present invention provides an air conditioning method. The form of the air conditioner is not limited in any way, and the air conditioner can be a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, a courtyard machine or other various forms of air conditioners. Fig. 1 to 4 illustrate an embodiment of a wall-mounted type air conditioner.
Fig. 1 is a schematic structural view of an air conditioner according to an embodiment of the present invention; fig. 2 is an enlarged side view of the air conditioner shown in fig. 1 when the air deflector 50 is at the maximum wind outlet angle; fig. 3 is a schematic view of the air conditioner shown in fig. 2 when the air deflector 50 is in an upward air guiding state; fig. 4 is a schematic view of the air conditioner shown in fig. 2 when the air deflector 50 is in a downward air guiding state.
As shown in fig. 1 to 4, an air conditioner of an embodiment of the present invention includes a case 10 for accommodating main components of the air conditioner, including a heat exchanger, a fan, a controller, and the like. The housing 10 is provided with an air outlet 12 for blowing out heat exchange air flow. The fan 30 is used for driving indoor air to enter the housing 10, so that cold air or hot air is formed after heat exchange between air flow and the heat exchanger is completed, and then the air is blown out through the air outlet 12. The air conditioner further includes a plurality of wind deflectors 50 for guiding the upper and lower wind outlet angles of the wind outlet 12, and each wind deflector 50 is rotatably installed on the housing 10 for guiding the upper and lower wind outlet angles of the wind outlet 12.

The plurality of air deflectors 50 are divided into a plurality of groups along the transverse direction of the casing 10, and each group includes an upper air deflector 50 and a lower air deflector 50. For example, as shown in fig. 1, the air guiding plates 50 are divided into two groups, and the total number is four.
Each air deflector 50 is individually coupled to a motor (not shown), and each motor is individually controlled by the controller 800. So, make the air conditioner more refine to the regulation of upper and lower air-out angle. For example, as shown in fig. 2, the air deflector 50 may be in the maximum air outlet state, and at this angle, the air deflector 50 may minimize the obstruction to the airflow, so that the airflow may be blown outward along the normal direction of the outlet 12 as much as possible, and the air volume may be maximized. As shown in fig. 3, the air deflector 50 has an upward air guiding state, that is, the heat exchange air flow is guided upward as much as possible, and the air guiding state can be selected when the air conditioner is used for cooling. Note that, in the upward air guiding state, it is not necessary to guide the air upward obliquely for each air guide plate 50, and the upward air guiding function may be realized by matching a plurality of air guide plates 50, and as shown in fig. 3, the rear air guide plate 50 guides the air forward, the air flow is guided to the front air guide plate 50, and the air flow is guided upward by the front air guide plate 50. As shown in fig. 4, the air guide plate 50 has a downward air guiding state, that is, the heat exchange air flow is guided downward as much as possible, and the air guiding state can be selected when the air conditioner is heating. In addition, the left air guide plate 50 may be closed to place the right air guide plate 50 in the upward air guiding state. Of course, more air guiding modes can be obtained by combining the air guiding states of the air deflectors 50, which is not described in detail herein.
Fig. 5 is a schematic block diagram of an air conditioner according to an embodiment of the present invention;
as shown in fig. 5, the air conditioner of the embodiment of the present invention further includes a controller 800. The controller 800 includes a processor 810 and a memory 820, the memory 820 stores a computer program 821, and the computer program 821 is used to implement the control method of the air conditioner according to any embodiment of the present invention when being executed by the processor 810.
In another aspect, the present invention provides a control method of an air conditioner.
Fig. 6 is a schematic diagram of a control method of an air conditioner according to an embodiment of the present invention.
As shown in fig. 6, a control method of an air conditioner according to an embodiment of the present invention may generally include:
step S602: when the air conditioner operates in a refrigerating or heating mode, the intelligent temperature control instruction is received, and the air conditioner is controlled to refrigerate or heat in a preset intelligent temperature control mode.
Specifically, when the user wants to operate the air conditioner in the intelligent temperature control mode, the user can perform corresponding operations on the remote controller, the line controller, the control panel of the air conditioner host, or other intelligent terminal devices wirelessly connected to the air conditioner, so that the user can send an opening instruction of the intelligent temperature control mode to the controller 800 of the air conditioner.
Step S604: and (3) operating a plurality of preset operating stages of the intelligent temperature control mode in sequence, wherein in every two adjacent stages, the opening number of the air deflectors 50 in the later stage is reduced compared with that in the earlier stage.
In the control method of the air conditioner, the air conditioner is provided with a plurality of air deflectors 50, and an intelligent temperature control mode is preset. The intelligent temperature control mode is divided into a plurality of operation stages, and the opening number of the air deflector 50 is less in the later stage, so that the effective air outlet area of the air outlet 12 is smaller and smaller, and the air quantity and the air outlet coverage range are gradually reduced along with the fact that the indoor temperature is gradually close to the comfortable interval of the user in the refrigeration/heating process, the wind sensation of the user is gradually reduced, and the body feeling of the user is enabled to be more comfortable.
In some embodiments, when the intelligent temperature control mode operates the refrigeration, the target refrigeration temperature of the later stage in every two adjacent stages is less than or equal to the target refrigeration temperature of the former stage. When the intelligent temperature control mode operates for heating, the heating target temperature of the later stage in every two adjacent stages is greater than or equal to the heating target temperature of the former stage. In this way, the cooling target temperature is set lower/the heating target temperature is set higher in the initial stage, so that the compressor is caused to operate at a higher frequency, the cooling/heating amount of the air conditioner is made larger, and the indoor temperature is made to fall/rise more quickly, so that the indoor environment is taken out of the hot/cold state as soon as possible.
After the initial stage, the indoor environment temperature has changed significantly, and if the air conditioner continues to operate quickly and with high power, the power consumption of the compressor is large, and the power consumption of the air conditioner is too large. Therefore, in a later operation stage, the cooling target temperature is gradually increased/the heating target temperature is decreased in order to down-convert the compressor.
When the intelligent temperature control mode is used for running refrigeration, the switching condition of each two adjacent stages is that the running time of the front stage reaches preset time or the indoor environment temperature reaches preset temperature, and the preset temperature is lower than the target refrigeration temperature of the rear stage. When the intelligent temperature control mode operates to heat, the switching condition of each two adjacent stages is that the operation time of the previous stage reaches the preset time or the indoor environment temperature reaches the preset temperature, and the preset temperature is greater than the heating target temperature of the later stage. Of course, it will be appreciated that the handover conditions between the different phases need not be the same. The air conditioner may be provided with a temperature detection module 40 for detecting an indoor ambient temperature.
In some embodiments, during the initial operation stage of the intelligent temperature control mode, the opened air deflector 50 is at the maximum air outlet angle, as shown in fig. 2. In the rest operation stages of the intelligent temperature control mode, when cooling is performed, the opened air deflector 50 is in an upward air guiding state, as shown in fig. 3, so that the air flow of cold air is guided upward, the cold air descends after reaching the roof, a shower type cooling effect is formed, and cold air is prevented from blowing people. When heating, the opened air deflector 50 is in a downward air guiding state, so that hot air can reach the ground better, and the foot warming experience is realized.
In some embodiments, during the initial operation stage of the intelligent temperature control mode, all the air deflectors 50 are turned on, so that the effective air outlet area of the air outlet 12 is maximized.
Further, the number of the air deflectors 50 may be the same as the number of the operation stages of the intelligent temperature control mode. When all the air deflectors 50 are turned on, one air deflector 50 is turned off in each operation switching stage. That is, in the final operation stage, only one air deflection plate 50 is kept in the open state.
In some embodiments, in each two adjacent phases of the intelligent temperature control mode, the rotation speed of the fan 30 in the later phase is less than that in the former phase.
In some embodiments, the air conditioner includes a plurality of swing blades 60 for adjusting a lateral wind outlet angle of the wind outlet 12. In the initial operation stage in the intelligent temperature control mode, the swinging blade 60 is at the maximum air outlet angle, and in the other operation stages, the swinging blade 60 is transversely and repeatedly swept.
In the above embodiment of the present invention, in the initial operation stage of the intelligent temperature control mode, the air deflector 50 is at the maximum air outlet angle, all the air deflectors 50 are turned on, the rotation speed of the fan is maximized, the target cooling temperature is set to be the lowest in each stage or the target heating temperature is set to be the highest in each stage, so that the cooling/heating is performed at the fastest speed in the initial stage, so as to make the indoor temperature reach the comfortable temperature zone of the human body more quickly. The cooling amount/heating amount is gradually decreased at a later stage, and the cooling target temperature is increased/the heating target temperature is decreased so as to slow down the cooling/heating speed to reduce the compressor power, thereby maintaining the indoor environment in a low wind and comfortable state and making the human body feel more comfortable.
Fig. 7 is a flowchart illustrating an air conditioner control method according to an embodiment of the present invention.
In some embodiments, as shown in fig. 7, the intelligent temperature control mode may be preset with four operation stages, which are an initial stage, a second stage, a third stage and a final stage. The control method of the air conditioner of this embodiment sequentially performs the following steps.
Step S702: and receiving an intelligent temperature control instruction during the refrigerating or heating operation.
Step S704: and controlling the air conditioner to operate in an intelligent temperature control mode preset initial stage.
And (3) refrigerating operation: the target cooling temperature at the initial stage is lower than the target cooling temperature set by the general user. For example, it is customary for a general user to set the cooling temperature between 25 ℃ and 29 ℃, so that the target temperature for the initial stage of cooling may be set between 16 ℃ and 20 ℃, for example, 18 ℃. The cooling target temperature is set lower at the initial stage of cooling so as to cause the compressor to operate at a higher frequency, so that the cooling capacity of the air conditioner is greater and the indoor temperature is more rapidly decreased. Meanwhile, the rotation speed of the fan 30 can be set at the highest gear, the swing vanes 60 are controlled to be in the maximum air-out state, and all the air deflectors 50 are opened and adjusted to be in the maximum air-out state.
Heating operation: the difference from the cooling operation is that the heating target temperature can be set at 30 ℃, and the electric auxiliary heating module is started.
Step S706: and judging whether a preset first switching condition is met. If yes, go to step S708; if not, the process returns to step S704.
And (3) refrigerating operation: the first preset condition may be: the operation time of the initial stage reaches a first preset time or the indoor environment temperature is less than or equal to a first refrigeration preset temperature, and the first refrigeration preset temperature is less than the refrigeration target temperature of the second stage. When one of the two conditions is satisfied, it can be determined that the first switching condition is satisfied. The first preset duration ranges from 1min to 5min, for example, 3min. The first refrigerated preset temperature may be 20 ℃.
The first preset condition may be: the operation time of the initial stage reaches a first preset time or the indoor environment temperature is greater than or equal to a first heating preset temperature, and the first heating preset temperature is greater than the heating target temperature of the second stage. When one of the two conditions is satisfied, it can be determined that the first switching condition is satisfied. The first preset duration ranges from 1min to 5min, for example, 3min. The first heating preset temperature may be 28 ℃.
Step S708: and controlling the air conditioner to operate in a preset intelligent temperature control mode.
And (3) refrigerating operation: after the initial stage of refrigeration, the indoor environment temperature is obviously reduced, and if the air conditioner is continuously refrigerated and operated quickly and in high power, the power consumption of the compressor is larger and the power consumption of the air conditioner is too large. Therefore, when the preset first switching condition is met, the air conditioner is switched to operate the second stage in time, the target refrigeration temperature is increased, and the compressor is subjected to frequency reduction. For example, the target temperature of the second stage refrigeration may be 24 ℃. In addition, the fan 30 can operate at the second high gear, so that the swing blades 60 swing air left and right in a reciprocating manner, one air guide plate 50 is closed, and the rest air guide plates 50 are adjusted to an upper air guide angle.
Heating operation: the difference from the cooling operation is that the heating target temperature can be set at 27 ℃, and the opened air guide plate 50 is adjusted to the downward air guide angle.
Step S710: and judging whether a preset second switching condition is met. If yes, go to step S712; if not, the process returns to step S708.
And (3) refrigerating operation: the second predetermined condition may be: the second-stage operation time length reaches a second preset time length or the indoor environment temperature is less than or equal to a second refrigeration preset temperature, and the second refrigeration preset temperature is less than the refrigeration target temperature of the third stage. The second preset duration ranges from 3min to 8min, for example, 5min. The second refrigeration preset temperature may be 20 ℃.
The heating operation, the second preset condition may be: the second-stage operation time reaches a second preset time or the indoor environment temperature is greater than or equal to a second heating preset temperature, and the second heating preset temperature is greater than the heating target temperature of the third stage. The second preset duration ranges from 3min to 8min, for example, 5min. The preset temperature for second heating may be 26 ℃.
Step S712: and a third stage of controlling the air conditioner to operate in an intelligent temperature control mode.
