Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The scope that swings up and down of air-conditioner air ducting as shown in Figure 1.Air ducting 1 is maximum angle Amax with the included angle A of vertical line a-b when air ducting is positioned at the top, and being minimum angles Amin when being positioned at bottom, is A0 when being positioned at maximum air outlet angle.
Fig. 2 is the relation schematic diagram between the air quantity of air-conditioner and the movement angle of air ducting, as seen from the figure: air ducting is at A0 place, and the air quantity of air-conditioner is maximum.
Fig. 3 is the realization flow figure of the air-conditioner wind direction control method that the embodiment of the present invention provides; For convenience of explanation, illustrate only part related to the present embodiment, as shown in the figure:
Step S11: obtain temperature parameter value T.
Step S12: the running status judging air-conditioner, if refrigeration, air-supply or except under wet condition, enters step S13; If under heating state, enter step S14.
Step S13: temperature parameter value T is higher, controls air ducting and moves to more close to the angle A 0 of maximum air output; Temperature parameter value T is lower, controls air ducting and moves to more close to the top angle A max.
Step S14: temperature parameter value T is lower, controls air ducting and moves to more close to the angle A 0 of maximum air output; Temperature parameter value T is higher, controls air ducting and moves to more close to bottom angle A min.
According to the control method of the air-conditioner wind direction that the embodiment of the present invention provides, suppose that in specific implementation process, temperature parameter value T is indoor real time temperature T1, in refrigerating state, air-supply or except under wet condition, indoor real time temperature T1 is higher, controlling air ducting moves to more close to the angle A 0 during maximum air output, now air quantity is comparatively large, and the ability that can promote air-conditioning exports, and allows room lower the temperature as early as possible; And the zone of action air quantity of people is maximum, the cool feeling brought by wind can be increased to make up the higher problem of room temperature.After indoor real time temperature T1 reduces, control air ducting and up move, thus reduce air quantity, the ability reducing air-conditioner exports, and also reduces room wind speed, reduces the cool feeling that has wind to bring with the lower problem of compensate for variations in ambient temperature.When heating state, indoor real time temperature T1 is lower, and air ducting is the closer to maximum air outlet angle A0, and air-out volume is larger, makes indoor temperature increase to accelerate warm braw diffusion; Indoor real time temperature T1 is higher, air ducting, more close to bottom angle A min, to reduce air-out volume, reduces air conditioning capacity and exports, and make comparatively warm air toward ground top blast, to be deposited in overhead room place because atmospheric density is less to avoid warm air, to cause the temperature of the zone of action of people lower.
In specific implementation process, two not identical temperature thresholds can be set respectively according to different running statuses in advance, judge that temperature parameter value T is higher or on the low side with this.Such as be defined as the first preset temperature value Ta and the second preset temperature value Tb, and Ta > Tb.Following table is the value example of the first preset temperature value Ta and the second preset temperature value Tb under different running status:
Therefore, for in refrigeration, air-supply or except the step S13 performed under wet condition, when the indoor real time temperature T1 obtained is greater than the first preset temperature value Ta (namely 26 DEG C or 28 DEG C), control the angle A 0 (namely 63 °) that air ducting moves to maximum air output; When indoor real time temperature T1 is less than the second preset temperature value Tb (namely 24 DEG C, 22 DEG C or 18 DEG C), controls air ducting and move to the top angle A max (namely 110 °); When indoor real time temperature T1 is between the second preset temperature value Tb and the first preset temperature value Ta, the motion control target location Am of air ducting and the linear negative correlativing relation of described temperature parameter value T.
For heating the step S14 performed under state, when indoor real time temperature T1 being greater than the first preset temperature value Ta (namely 24 DEG C), controlling air ducting and moving to bottom angle A min (namely 30 °); When indoor real time temperature T1 is less than the second preset temperature value Tb (namely 16 DEG C), control the angle A 0 (namely 63 °) that air ducting moves to maximum air output; When indoor real time temperature T1 is between the second preset temperature value Tb and the first preset temperature value Ta, the motion control target location Am of air ducting and the linear negative correlativing relation of temperature parameter value T.
Further, under above-mentioned different running status, when indoor real time temperature T1 is between the second preset temperature value Tb and the first preset temperature value Ta, the motion control target location Am of air ducting all with the linear negative correlativing relation of indoor real time temperature T1.So-called linear negative dependency relation, can be expressed as:
Am=﹣ K ﹡ T1 ﹢ b, wherein Tb≤T1≤Ta, K, b are default positive number.
As a preferred embodiment, described linear negative dependency relation can be specially:
In refrigeration, air-supply or except under wet condition,
If heating under state,
It should be noted that, linear negative dependency relation formula provided herein is only example and illustrates, and is not used in the execution and realization that limit this step.
In another preferred embodiment of the present invention, when for the temperature parameter value T of indoor real time temperature T1 between the second preset temperature value Tb and the first preset temperature value Ta time, after calculating obtains the motion control target location Am of air ducting, also need the current angular Ad judging air ducting whether identical with this target location Am; If current angular Ad is identical with target location Am, then air ducting does not move; If current angular Ad is not identical with target location Am, then needs to control air ducting and move to target location Am.
Fig. 4 is the realization flow figure of the air-conditioner wind direction control method that another preferred embodiment of the present invention provides.In the present embodiment, the concrete value of temperature parameter value T is also indoor real time temperature T1.Process step is as shown in the figure:
In the step s 21, indoor real time temperature T1 is obtained.
In step S22, judge the running status of air-conditioner, if refrigeration, air-supply or except under wet condition, enter step S23; If under heating state, enter step S24.
In step S23, indoor real time temperature T1 and the first preset temperature value Ta, the second preset temperature value Tb are compared: as T1 > Ta, control the angle A 0 that air ducting moves to maximum air output; As T1 < Tb, control air ducting and move to the top angle A max; As Tb≤T1≤Ta, the motion control target location of air ducting
In step s 24 which, indoor real time temperature T1 and the first preset temperature value Ta, the second preset temperature value Tb are compared: as T1 > Ta, control air ducting and move to bottom angle A min; As T1 < Tb, control the angle A 0 that air ducting moves to maximum air output; As Tb≤T1≤Ta, the motion control target location of air ducting
As a preferred embodiment, in the flow process of the control method of the air-conditioner wind direction shown in Fig. 4, further comprising the steps of:
In step s 25, after calculating obtains the motion control target location Am of air ducting, judge that whether the current angular Ad of air ducting is identical with this target location Am; If current angular Ad is identical with target location Am, perform step S26; If current angular Ad is not identical with target location Am, perform step S27.
In step S26, air ducting does not move.
In step s 27, control air ducting and move to target location Am.
Further, as a more excellent embodiment, this control system of air-conditioner also without real time temperature T1 in moment ceaselessly sensing chamber, but takes the mode obtaining once indoor real time temperature T1 at interval of certain hour t.
Like this, just determined the movement angle of air ducting by indoor real time temperature T1, benefit is:
In refrigeration, air-supply or except under wet condition: indoor real time temperature T1 is higher, air ducting is the closer to maximum air outlet angle A0, now air-out volume is larger as shown in Figure 2, thus the ability promoting air-conditioning exports, and allows room lower the temperature as early as possible, increases cool feeling or dehumidifying, also strengthen wind speed, the cool feeling that increase is brought by wind is to make up the larger problem of room temperature, when air ducting angle reaches maximum air outlet angle A0, the zone of action air quantity of people is maximum, brings maximum pleasantly cool sense to user.Indoor real time temperature T1 is lower, air ducting is more close to the top angle, air-out volume is fewer, air conditioning capacity exports lower, with reduce have wind to bring cool feeling with the lower problem of compensate for variations in ambient temperature, when air ducting angle reaches the top angle A max, in general, wind directly can not blow to the zone of action of people, this avoid cold wind and blows to the brought sense of discomfort of user with it.
Heating under state: indoor real time temperature T1 is lower, and air ducting is the closer to maximum air outlet angle, and air-out volume is larger, making indoor temperature increase to accelerate warm braw diffusion; Indoor real time temperature T1 is higher, air ducting, more close to bottom angle, to reduce air-out volume, reduces air conditioning capacity and exports, and make comparatively warm air toward ground top blast, be deposited in overhead room place to avoid warm air because atmospheric density is less and cause the zone of action temperature of people lower.
Further, temperature parameter value T in the various embodiments described above is for indoor real time temperature T1, in fact, other similar temperature such as user's design temperature Ts, air outlet temperature value Tc, outdoor temp angle value Tw or the temperature difference T between indoor real time temperature and design temperature can also be obtained as temperature parameter value T to control the movement angle of air ducting.
Adopt design temperature Ts for temperature parameter value T below, the implementation procedure of the control method of air-conditioner wind direction provided by the invention is described.
With reference to the various embodiments described above, user's design temperature is Ts, and the controlling value first preset temperature value Ta of default settings temperature and the second preset temperature value Tb, and Ta and Tb is under different running statuses, has different scopes.The scope of above-mentioned parameter is as shown in the table:
When user's design temperature changes, detect current user's design temperature Ts, and judge the running status of current air-conditioner: in refrigeration with except under wet condition, design temperature Ts is higher, controlling air ducting moves to more close to the angle A 0 during maximum air output, design temperature Ts is lower, controls air ducting and moves to more close to the top angle A max; Heating under state, design temperature Ts is lower, and control air ducting and move to more close to the angle A 0 during maximum air output, design temperature Ts is higher, controls air ducting and moves to more close to bottom angle A min.
Concrete, in refrigeration with except under wet condition, when user's design temperature Ts is greater than the first preset temperature value Ta, control air ducting moves to the angle A 0 during maximum air output, when user's design temperature Ts is less than the second preset temperature value Tb, control air ducting and move to the top angle A max, when user's design temperature Ts is between the first preset temperature value Tb and the second preset temperature value Ta, the motion control target location Am of air ducting and the linear negative correlativing relation of design temperature Ts.Description above can be expressed as:
As Ts > Ta, Am=A0;
As Tb≤TS≤Ta,
As Ts<Tb, Am=Amax.
Concrete, heating under state, when user's design temperature Ts is greater than the first preset temperature value Ta, control air ducting and move to bottom angle A min, when user's design temperature Ts is less than the second preset temperature value Tb, control air ducting moves to the angle A 0 during maximum air output, when user's design temperature Ts is between the second preset temperature value Tb and the first preset temperature value Ta, and the motion control target location Am of air ducting and the linear negative correlativing relation of design temperature Ts.Foregoing description also can be expressed as:
As Ts > Ta, Am=Amin;
As Tb≤TS≤Ta,
As Ts<Tb, Am=A0.
Same, the movement angle of air ducting is determined by user's design temperature Ts, also mainly for the consideration of user's comfort, such as under refrigerating state, the operation of air-conditioner has a comfort temperature interval, if but due to the maloperation of user, cause design temperature Ts too high, so control air ducting more close to the angle A 0 during maximum air output, strengthen wind speed, at least can also increase the cool feeling brought by wind; If design temperature Ts is too low, then controlling air ducting moves to more close to the top angle A max, air-out volume is fewer, air conditioning capacity exports lower, with reduce have wind to bring cool feeling with the lower problem of compensate for variations in ambient temperature, when the angle of air ducting reaches the top angle A max, in general, wind directly can not blow to the zone of action of people, this avoid cold wind and blows to the brought sense of discomfort of user with it.In dehumidifying with under heating state, all similar, just repeat no more at this.
