Description
Technical Field
The invention relates to the technical field of air conditioning, in particular to an air conditioner and a control method thereof.
Background
With the improvement of living standard, air conditioners have become indispensable electric appliances for home and commercial occasions. Air conditioners typically have a wide variety of adjustment options for users to adjust. For example, the user can adjust the target temperature and the wind speed of the air conditioner, the wind guiding direction (i.e., the up-down wind guiding state) of the wind deflector, and the wind guiding direction of the swing blade.
However, many users only set a target temperature when using the air conditioner, and have little attention or initiative in using other adjustment functions. Some users are interested in performing combined adjustment and frequent adjustment on various adjustment functions of the air conditioner, but the best cooling effect is difficult to obtain due to lack of professional knowledge.
Disclosure of Invention
The present invention is directed to solve at least one of the above-mentioned drawbacks of the prior art and to provide an air conditioner with an intelligent energy-saving control mode and a control method thereof.
A further object of the present invention is to provide an air conditioner that can both increase the cooling/heating rate and meet the comfort needs of the user.
In one aspect, the present invention provides a method for controlling an air conditioner, where the air conditioner includes a plurality of air deflectors for guiding upper and lower air outlet angles of an air outlet, and the method includes:
receiving a control instruction for refrigerating or heating in an intelligent temperature control mode;
operating an initial stage of the intelligent temperature control mode, wherein the initial stage has a refrigerating target temperature or a heating target temperature;
after a preset first switching condition is met, the air conditioner is switched to operate in a middle stage of the intelligent temperature control mode, and the rotating speed of a fan in the middle stage is lower than that in the initial stage;
and after a preset second switching condition is met, the air conditioner is switched to operate the last stage of the intelligent temperature control mode, wherein the opening number of the air deflectors of the last stage is smaller than that of the middle stage.
Optionally, when the intelligent temperature control mode operates refrigeration, the first preset condition includes: the running time of the initial stage reaches a first preset time and the indoor temperature is lower than a preset refrigeration node temperature, and the refrigeration node temperature is higher than the refrigeration target temperature;
when the intelligent temperature control mode operates to heat, the first preset condition comprises: the running time of the initial stage reaches a first preset time, the indoor temperature is higher than a preset heating node temperature, and the heating node temperature is lower than the heating target temperature.
Optionally, when the intelligent temperature control mode operates in the cooling mode, the second preset condition includes: the running time of the middle stage reaches a second preset time, and the indoor temperature is equal to or less than the refrigeration target temperature;
when the intelligent temperature control mode operates to heat, the second preset condition comprises: the operation time of the middle period reaches a second preset time, and the indoor temperature is equal to or greater than the heating target temperature.
Optionally, when the intelligent temperature control mode operates in the cooling mode, the second preset condition further includes: in the middle stage, the reduction value of the body surface temperature of the indoor human body exceeds a preset temperature reduction value;
when the intelligent temperature control mode operates to heat, the second preset condition further comprises: in the middle stage, the rise value of the surface temperature of the indoor human body exceeds a preset temperature rise value.
Optionally, when the intelligent temperature control mode operates for refrigeration, the opened air deflector is enabled to swing to and fro to sweep air;
and when the intelligent temperature control mode operates for heating, the opened air guide plate is in a lower air guide state in the initial stage and the middle stage, and the opened air guide plate is subjected to reciprocating swing air sweeping in the final stage.
Optionally, all air deflectors are turned on in the early stage and the middle stage.
Optionally, when the intelligent temperature control mode operates to heat, the electric heating device of the air conditioner is turned on in the initial stage and the middle stage.
Optionally, the air conditioner further comprises a plurality of swing blades for guiding the transverse wind outlet angle of the wind outlet;
in the initial stage, enabling each swing blade to be at the maximum air outlet angle;
and in the middle stage and the final stage, enabling each oscillating blade to perform reciprocating oscillation wind sweeping.
In another aspect, the present invention also provides an air conditioner, including:
a shell which is provided with an air outlet;
the air guide plates are rotatably arranged on the shell and used for guiding the upper air outlet angle and the lower air outlet angle of the air outlet; and
a controller comprising a processor and a memory, the memory storing a computer program for implementing the control method according to any of the above when executed by the processor.
Optionally, the plurality of air deflectors are divided into a plurality of groups along the transverse direction of the casing, and each group includes an upper air deflector and a lower air deflector.
In the control method of the air conditioner, the air conditioner has an intelligent temperature control mode, the intelligent temperature control mode is divided into a plurality of operation stages, and different operation stages play different roles. After the rapid cooling/heating is performed in the initial stage, the indoor temperature is brought very close to the user's comfort zone. The rotating speed of the fan is reduced in the middle stage so as to reduce the wind sensation of a user and make the user feel more comfortable. In the final stage, when the indoor temperature reaches a comfortable interval, part of the air deflectors are closed, so that the effective air outlet area of the air outlet is reduced, the flow of indoor cold air/hot air is further reduced, and the human body feels quieter and more comfortable.
Further, in the control method of the air conditioner, the rotating speed of the fan is reduced in the middle stage of the intelligent temperature control mode, so that the refrigerating/heating speed is slowed down. The end stage functions primarily to maintain the cooling/heating effect and therefore also to turn off part of the air deflector, which inevitably results in a weaker cooling/heating capacity. Therefore, the invention particularly designs a step for detecting the change of the body surface temperature of the human body, and the terminal stage is switched only when the change of the body surface temperature of the human body reaches the preset standard, which indicates that the human body perceives sufficient cooling/heating effect, so as to avoid the feeling of unobvious cooling/heating effect brought to the user by too early switching.
The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments thereof, taken in conjunction with the accompanying drawings.

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 illustrating 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 guide plate 50 is in a downward air guiding state.
As shown in fig. 1 to 4, the air conditioner of the embodiment of the present invention includes a case 10 for accommodating main components of the air conditioner, including a heat exchanger, a fan 30, a controller 800, and the like. The housing 10 is provided with an air outlet 12 for blowing out a heat exchange air flow. The fan 30 is used for causing indoor air to enter the housing 10, so that cold air or hot air is formed after the air flow exchanges heat with the heat exchanger, and then the cold air or the hot 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.
In some embodiments, as shown in fig. 1, for a wall-mounted air conditioner, each air deflection plate 50 may be rotatably mounted to the housing 10 about a horizontal transverse axis. 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 two upper and lower air deflectors 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 airflow 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 guiding plates 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: and receiving a control instruction for refrigerating or heating in an intelligent temperature control mode.
That is, the air conditioner has corresponding intelligent temperature control modes when refrigerating in summer and heating in winter.
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 operating the initial stage of the intelligent temperature control mode.
The stage has a target refrigeration temperature or a target heating temperature, and a vapor compression refrigeration cycle system of the air conditioner operates by taking the target refrigeration temperature or the target heating temperature as a target to regulate and control components such as a compressor, an expansion valve and the like. For example, the cooling target may be set at 18 ℃ to 24 ℃, and the heating target may be set at 24 ℃ to 30 ℃.
Step S606: and judging whether a preset first switching condition is met. If yes, go to step S608; if not, the process returns to step S604.
Step S608: and switching the air conditioner to operate in the middle stage of the intelligent temperature control mode.
The rotation speed of the fan 30 in the middle stage is lower than that of the fan 30 in the initial stage. In addition, the target cooling temperature in the middle stage is not changed from that in the initial stage, as compared with that in the initial stage.
Step S610: and judging whether a preset second switching condition is met. If yes, go to step S612; if not, the process returns to step S608.
Step S612: and switching the air conditioner to operate in the final stage of the intelligent temperature control mode. The number of air deflectors 50 opened in the final stage is smaller than in the intermediate stage.
The embodiment of the invention enables the air conditioner to have an intelligent temperature control mode, the intelligent temperature control mode is divided into a plurality of operation stages, and different operation stages play different roles. After the rapid cooling/heating is performed at the initial stage, the indoor temperature gradually approaches the user's comfort zone. Therefore, the rotating speed of the fan is reduced in the middle stage, so that the wind sensation of a user is reduced, and the user feels more comfortable. In the final stage, when the indoor temperature reaches the comfortable interval, the air deflector 50 is partially closed, so that the effective air outlet area of the air outlet 12 is reduced, the flow of indoor cold air/hot air is further reduced, and the human body feels more silent and comfortable.
In some embodiments, when the cooling is operated in the smart temperature control mode, the first preset condition includes: the operation time of the initial stage reaches a first preset time and the indoor temperature is lower than the preset refrigeration node temperature, and the refrigeration node temperature is higher than the refrigeration target temperature. The first preset duration ranges from 1min to 5min, for example, 3min. The refrigeration target temperature may be 22 deg.c and the refrigeration node temperature may be 26 deg.c.
Similarly, when the intelligent temperature control mode is operated to heat, the first preset condition comprises: the operation time of the initial stage reaches a first preset time, the indoor temperature is higher than the preset heating node temperature, and the heating node temperature is lower than the heating target temperature. The first preset duration ranges from 1min to 5min, for example, 3min. The heating target temperature may be 26 ℃, and the heating node temperature may be 20 ℃.
That is, in the embodiment of the present invention, in the initial stage, although the target temperature is not reached yet in the cooling/heating process, the temperature is close to the target temperature, so that the intermediate stage is switched in time to reduce the rotation speed of the fan, so as to avoid that the fan 30 is always operated at a high rotation speed to cause too much indoor noise and too strong wind sensation.
In some embodiments, when the cooling is operated in the smart temperature control mode, the second preset condition includes: the operation time of the middle period reaches a second preset time, and the indoor temperature is equal to or less than the target refrigerating temperature. The second preset duration ranges from 8min to 15min, for example, 10min. When the intelligent temperature control mode operates to heat, the second preset condition comprises: and the operation time of the middle stage reaches a second preset time, and the indoor temperature is equal to or more than the heating target temperature.
Therefore, when the indoor environment temperature reaches the target temperature in the final stage of operation, the compressor can be stopped or operated at the lowest frequency, and the indoor environment temperature can be kept in a comfortable interval.
Further, when the intelligent temperature control mode is operated for refrigeration, the second preset condition further comprises: in the middle stage, the body surface temperature of the human body in the room is reduced by a value exceeding a preset temperature drop value, which can be between 0.2 ℃ and 0.8 ℃, for example 0.3 ℃. Similarly, when the intelligent temperature control mode is operated to heat, the second preset condition further comprises: in the middle stage, the body surface temperature of the indoor human body rises to exceed the preset temperature rise value. The predetermined temperature rise may be between 0.2 ℃ and 0.8 ℃, for example 0.3 ℃.
In some embodiments, when the cooling operation is performed in the intelligent temperature control mode, the opened air guide plate 50 performs reciprocating swing air sweeping to accelerate the diffusion speed of the outlet air flow and accelerate the cooling/heating process. When the intelligent temperature control mode is used for heating, the opened air deflector 50 is in the downward air guiding state in the initial stage and the middle stage, so that heating near the ground can be realized as soon as possible. In the final stage, the opened air deflector 50 is swept back and forth to keep the whole house warm.
Further, in the initial stage and the middle stage, all the air deflectors 50 are opened so as to maximize the effective air outlet area of the air outlet 12, increase the air volume and increase the cooling/heating speed.
In some embodiments, when the heating is performed in the intelligent temperature control mode, the electric heating device 90 of the air conditioner is turned on in the early stage and the middle stage to avoid insufficient heating capacity.
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. At the initial stage of the intelligent temperature control mode, each of the swing vanes 60 can be positioned at the maximum air outlet angle. That is, the large surface of each flap 60 is substantially parallel to the normal direction of the air outlet 12, and the edge of the flap 60 is faced to the air flow, so that the air flow is blocked to the minimum. In the middle stage and the final stage, the swing blades 60 are caused to swing and sweep wind in a transverse reciprocating manner.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
