(2-4-5) wind direction automatic mode
Wind direction automatic mode is the pattern of automatically adjusting the wind direction of blow out air, according to " operation mode " that set and automatic switchover wind direction.
And, when " upper and lower wind direction " is set to wind direction automatic mode, wind direction control part 61 is according to " operation mode " that set, selects the predetermined pattern of wind direction up and down from blowing up pattern, blowing down pattern and natural wind to pattern, carries out selected upper and lower wind direction pattern.
In addition, in the present embodiment, as long as beyond when " operation mode " is set as blowing, user can be set as wind direction automatic mode by " upper and lower wind direction ".And, in the present embodiment, in the situation that " operation mode " is set to humidification, even if " upper and lower wind direction " is set to wind direction automatic mode, also only carry out blowing up pattern.
For example, in the situation that " operation mode " is set to refrigeration or dehumidifying, wind direction control part 61 selects blowing up pattern and natural wind to pattern.Then, in the situation that meeting predetermined condition, wind direction control part 61 switching blowing up patterns and natural wind are to pattern.Therefore,, in the situation that " operation mode " is set to refrigeration or dehumidifying, " upper and lower wind direction " and is set to wind direction automatic mode, alternately carry out blowing up pattern and natural wind to pattern.
And, for example, at " operation mode ", being set to heat in the situation that, wind direction control part 61 is selected blowing up pattern and blowing down patterns.Then, in the situation that meeting predetermined condition, wind direction control part 61 switches blowing up pattern and blowing down pattern.Therefore, " operation mode " is set to and heats, " upper and lower wind direction " is set in the situation of wind direction automatic mode, alternately carries out blowing up pattern and blowing down pattern.
In addition, in the present embodiment, when " upper and lower wind direction " is set to wind direction automatic mode, wind direction control part 61 is in the situation that " operation mode " is set to refrigeration, from blowing up pattern, start to carry out, at " operation mode ", be set to heat in the situation that, according to indoor temperature, select any one party in blowing down pattern and blowing up pattern, from selected pattern, start to carry out.
And, as switching blowing down pattern or the natural wind predetermined condition to pattern and blowing up pattern, for example, enumerate the condition relevant with indoor environment, the condition relevant with the running-active status of air conditioner etc.
And, in the present embodiment, in the situation that " operation mode " is refrigeration, meet do not carry out more than heat exchange (Thermo OFF) state continuance certain hour (the more than 0 minute scheduled time) the such the 1st switching condition while freezing and from the difference of indoor temperature and design temperature, be predetermined temperature below more than through certain hour (the more than 0 minute scheduled time) during any one condition the such the 2nd switching condition while freezing, from blowing up pattern, switch to natural wind to pattern.And, in the situation that " operation mode " is refrigeration, meet from the difference of indoor temperature and design temperature be more than predetermined temperature more than through certain hour (the more than 0 minute scheduled time) during the such the 3rd switching condition while freezing, from natural wind to pattern, switch to blowing up pattern.
Here, in the present embodiment, in the situation that " operation mode " is set to refrigeration, " upper and lower wind direction " and is set to wind direction automatic mode, execution from blowing up pattern, so, when refrigeration, after making indoor temperature stable by circulating current, switch to blow out air contact user's natural wind to pattern.Thus, even if make blow out air contact user when carrying out natural wind to pattern, also can reduce the possibility that user is caused to discomfort.
And, at " operation mode " for heat in the situation that, meet from the difference of indoor temperature and design temperature be below predetermined temperature through certain hour (the more than 0 minute scheduled time) more than, and from the operating frequency of compressor be preset frequency below through more than certain hour (the more than 0 minute scheduled time) the such the 1st switching condition while heating, with from switching to while not carrying out heat exchange state through any one condition in more than certain hour (the more than 0 minute scheduled time) the such the 2nd switching condition while heating by carrying out heat exchange (Thermo ON) state, from blowing down pattern, switch to blowing up pattern.And, at " operation mode ", for heat in the situation that, during such the 3rd switching condition while heating, from blowing up pattern, switch to blowing down pattern meeting from switching to blowing up pattern through the scheduled time (being defaulted as 1 minute).
In addition, the scheduled time of the 3rd switching condition while heating can be at 0(except 0 second) change in～the scope of 30 minutes, but, the air in order to form circulating current in teeter chamber, preferably the scheduled time is set in the scope more than 30 seconds, below 5 minutes.
(3) wind direction during execution wind direction automatic mode while heating is controlled
The setting indication of accepting wind direction automatic mode at control device 60 from user is during as the setting of " upper and lower wind direction ", at " operation mode ", be set to heat in the situation that, wind direction control part 61 judges whether the difference of current indoor temperature and design temperature is below predetermined temperature, according to judged result, carries out any one pattern in blowing up pattern and blowing down pattern.
In the situation that the difference of current indoor temperature and design temperature is below predetermined temperature, by making horizontal baffle 31 take level blowing posture and make attached wall baffle plate 32 take blowing up posture, carry out blowing up pattern.Thus, blow out air blows out towards indoor ceiling surface, can stir being trapped near warm braw indoor ceiling and the air of Near Ground.
On the other hand, in the situation that the difference of current indoor temperature and design temperature is greater than predetermined temperature, by making horizontal baffle 31 and attached wall baffle plate 32 take blowing down posture, carry out blowing down pattern.Thus, blow out air blows out towards ground, so, can heat energetically the air of Near Ground.
And, during any one condition when meeting the 1st switching condition and the 2nd while heating and heat in switching condition,, from the difference of indoor temperature and design temperature be predetermined temperature below through more than certain hour and from the operating frequency of compressor be preset frequency below through more than certain hour or from switching to and do not carry out when above through certain hour heat exchange state by carrying out heat exchange state, wind direction control part 61 switches to blowing up pattern by upper and lower wind direction pattern from blowing down pattern, carries out blowing up pattern temporarily.Thus, the posture that the posture of horizontal baffle 31 switches to level blowing posture and attached wall baffle plate 32 from blowing down posture switches to blowing up posture from blowing down posture, thus, blow out air blows out towards indoor ceiling surface temporarily, so, can stir being trapped near warm braw indoor ceiling and the air of Near Ground.
And when meeting the 3rd switching condition while heating, that is, from switching to blowing up pattern, during through the scheduled time, wind direction control part 61 switches to blowing down pattern by upper and lower wind direction pattern from blowing up pattern, carries out blowing down pattern more than certain hour.Thus, the posture that the posture of horizontal baffle 31 switches to blowing down posture and attached wall baffle plate 32 from level blowing posture switches to blowing down posture from blowing up posture, more than the posture of horizontal baffle 31 and attached wall baffle plate 32 (blowing down posture) maintains certain hour, so, blow out air blows out towards ground more than certain hour, can heat energetically the air of Near Ground.
Like this, wind direction control part 61 carries out following control (automatically switch and control): the in the situation that of carrying out wind direction automatic mode when heating, more than certain hour, take after blowing down posture making horizontal baffle 31 and attached wall baffle plate 32, make horizontal baffle 31 take level blowing posture temporarily, and make attached wall baffle plate 32 take blowing up posture.
(4) feature
（4-1）
In the present embodiment, the in the situation that of carrying out wind direction automatic mode when heating, the posture of horizontal baffle 31 is switched to level blowing posture from blowing down posture temporarily, and the posture of attached wall baffle plate 32 is switched to blowing up posture from blowing down posture.Therefore, warm braw blows out towards indoor ceiling surface temporarily, so, can take near warm braw ceiling that blowing down posture time lag stays within to stir to the air of Near Ground and horizontal baffle 31 and attached wall baffle plate 32.Like this, by indoor all air are stirred, the indoor temperature that can eliminate while heating is uneven.
And, in the present embodiment, by make horizontal baffle 31 and attached wall baffle plate 32 more than certain hour, take blowing down posture, thereby more than certain hour, make warm braw blow out towards indoor ground, so, before the air to indoor stirs, the air of the Near Ground in heating clamber energetically.
（4-2）
In the present embodiment, by making horizontal baffle 31 take level blowing posture, make attached wall baffle plate 32 take blowing up posture, thereby blow out air is become along the attached wall air-flow of the lateral surface 32a of attached wall baffle plate 32, to ceiling surface, guide.In this indoor apparatus of air conditioner 10, utilize horizontal baffle 31 and attached wall baffle plate 32 that blow out air is blown out towards indoor ceiling surface, thus, can form circulating current.
（4-3）
When making blow out air continue when ceiling surface blows out when heating, the air of Near Ground can not warm energetically, so the temperature of the air of Near Ground reduces, and may cause discomfort to user.
Therefore, in the present embodiment, when during through the scheduled time (if not change setting, be 1 minute), switch to blowing down pattern from blowing up pattern from blowing down pattern switches to blowing up pattern.In other words, the lasting scheduled time makes blow out air blow out towards ceiling surface.And the scheduled time can be at 0(except 0 second) change in～the scope of 30 minutes.That is,, in this indoor apparatus of air conditioner 10, the in the situation that of carrying out wind direction automatic mode when heating, the posture of horizontal baffle 31 takes time that level blowing posture and attached wall baffle plate 32 take blowing up posture longer and be below 30 minutes than 0 second.Like this, the time that blow out air blows out towards ceiling surface was to the maximum below 30 minutes, so, can reduce following possibility: the too low possibility of temperature of the air of Near Ground thereby the air of indoor Near Ground can not warm energetically.
（4-4）
In the present embodiment, meet from the difference of indoor temperature and design temperature be below predetermined temperature through certain hour more than and from the operating frequency of compressor, be below preset frequency the such the 1st switching condition while heating and from by carrying out heat exchange state while switching to more than not carrying out heat exchange state through certain hour any one condition in the such the 2nd switching condition while heating more than through certain hour,, after indoor temperature stabilization, from blowing down pattern, switch to blowing up pattern, blow out air blows out towards ceiling surface.Therefore, if indoor temperature is unstable, from blowing down pattern, do not switch to blowing up pattern, so, although the temperature of the air of Near Ground can not improve,, can reduce the possibility that the air of Near Ground can not warm energetically.
（4-5）
When the higher state of the temperature at blow out air is carried out blowing up pattern, the warm braw blowing out from blow-off outlet 15 may directly be trapped in ceiling.
Therefore, in the present embodiment, in the situation that from the operating frequency of compressor be below preset frequency through more than certain hour or from switching to and do not carry out heat exchange state, through more than certain hour, switching to blowing up pattern from blowing down pattern by carrying out heat exchange state.The temperature of the blow out air of the temperature of the blow out air while therefore, carrying out blowing up pattern when carrying out blowing down pattern.Therefore, in this indoor apparatus of air conditioner 10, the temperature of the blow out air blowing out towards ceiling surface is lower than the temperature of the blow out air blowing out towards ground, so, can reduce warm braw and be trapped near possibility ceiling.
(5) variation
(5-1) variation A
In the above-described embodiment, in order to make the wind direction of blow out air become the wind direction that forms circulating current, utilize horizontal baffle 31 and attached wall baffle plate 32.But as long as can make the wind direction of blow out air become the wind direction that forms circulating current, the structure of indoor apparatus of air conditioner 10 is not limited to this.For example, if only utilize horizontal baffle 31 just can make the wind direction of blow out air become the wind direction that forms circulating current, indoor apparatus of air conditioner 10 also can not have attached wall baffle plate 32.
And, in the above-described embodiment, preset the posture of horizontal baffle 31 and the posture of attached wall baffle plate 32 while carrying out blowing up pattern.Replace, if horizontal baffle 31 and attached wall baffle plate 32 angulations are in the scope below predetermined open angle, also can change the posture of horizontal baffle 31 and the posture of attached wall baffle plate 32.Thus, can form the circulating current corresponding with the indoor shape of indoor apparatus of air conditioner 10 and the barrier of ceiling etc. are set.
The posture of horizontal baffle 31 while in addition, carrying out blowing up pattern and the posture of attached wall baffle plate 32 can be according to operation modes and difference for example, can change by remote controller 80.
(5-2) variation B
In the above-described embodiment, carrying out when ceiling surface blows out the blowing up pattern of blow out air, do not carry out air quantity control.But even blow out blow out air towards ceiling surface, in the situation that the air quantity of blow out air is less, blow out air also cannot arrive indoor corner, sometimes cannot be formed on the circulating current of indoor all circulations.
Therefore, when upper and lower wind direction pattern is switched to blowing up pattern, also can adjust air quantity, to guarantee to form the needed minimum air quantity of circulating current.
For example, as shown in Figure 5, following situation is described: except wind direction control part 61, control device 60 also has the air quantity control part 162 of adjusting the air quantity of blow out air by the rotating speed of control room internal fan 14.In addition, except control device 60 has air quantity control part 162 these points, the structure of the indoor apparatus of air conditioner 10 of this variation is the structure identical with above-mentioned embodiment, so, only air quantity control part 162 is described below.
Air quantity control part 162, according to become the definite airflow value of mode of air quantity corresponding to the setting of " air quantity " that carry out via remote controller 80 with user, carries out the action control of indoor fan 14.In addition, the setting of " air quantity " refers to the air quantity of setting blow out air, and in this variation, as " air quantity ", user can select any one party of the fixing and air quantity of air quantity in automatically to set.
When " air quantity " is set to air quantity fixedly time, air quantity control part 162 is defined as the setting value corresponding with the predetermined wind amount setting by airflow value, and control room internal fan 14, to become the rotating speed corresponding with determined airflow value.And, at air quantity, fixedly time, as predetermined wind amount, according to air quantity order from big to small, can select air quantity H, air quantity M, air quantity L, air quantity control part 162 is defined as the setting value corresponding with the predetermined wind amount of selecting to set by airflow value.
And when " air quantity " is set to air quantity when automatic, air quantity control part 162 is according to indoor environment, select the setting value corresponding with any one air quantity in air quantity H, air quantity M and air quantity L, airflow value is defined as to selected setting value.For example, in the situation that the difference of indoor temperature and design temperature is larger, air quantity control part 162 is selected the setting value corresponding with air quantity H, along with the difference of indoor temperature and design temperature reduces, and selection and air quantity M, the setting value that air quantity L is corresponding.
And then when upper and lower wind direction pattern being switched to blowing up pattern by wind direction control part 61, air quantity control part 162 is determined airflow value, to guarantee to form the needed minimum air quantity of circulating current.In addition, in the situation that user is set as blowing up pattern or wind direction automatic mode by " upper and lower wind direction ", by wind direction control part 61, upper and lower wind direction pattern is switched to blowing up pattern.And, establish the setting value corresponding with forming the needed minimum air quantity of circulating current in this variation and the setting value corresponding with air quantity M and equate.
And, in the situation that " air quantity " is set to air quantity L, when upper and lower wind direction pattern is switched to blowing up pattern, air quantity control part 162 is to become the mode of the value more than setting value corresponding with air quantity M, in the setting value corresponding with air quantity L, add corrected value, determine airflow value.
In addition, the in the situation that of carrying out wind direction automatic mode when heating,, user is set as " operation mode " heat, " upper and lower wind direction " is set as in the situation of wind direction automatic mode, in the situation that " air quantity " is set as to air quantity L, when upper and lower wind direction pattern switches to blowing up pattern from blowing down pattern, air quantity control part 162 adds that in the setting value corresponding with air quantity L corrected value determines airflow value, thereby adjusts air quantity.On the other hand, user, " operation mode " is set as heating, will " upper and lower wind direction " be set as wind direction automatic mode, " air quantity " is set as to air quantity L in the situation that, when upper and lower wind direction pattern switches to blowing down pattern from blowing up pattern, it is the setting value that air quantity L is corresponding with " air quantity " that be set by the user that air quantity control part 162 is selected, airflow value is defined as to selected setting value, thereby adjusts air quantity.
Thus, even if user is set as air quantity L by " air quantity ", in during execution blowing up pattern, be also adjusted into air quantity more than air quantity M, so, can guarantee to form the needed minimum air quantity of circulating current, and, carry out blowing down pattern during in, can be adjusted into the air quantity (air quantity L) being set by the user.
And, at " air quantity ", be set in the automatic situation of air quantity, when upper and lower wind direction pattern is switched to blowing up pattern, air quantity control part 162 is according to indoor temperature and design temperature, select the setting value corresponding with any one air quantity in air quantity H or air quantity M, airflow value is defined as to selected setting value.
In addition, the in the situation that of carrying out wind direction automatic mode when heating,, user is set as " operation mode " heat, " upper and lower wind direction " is set as in the situation of wind direction automatic mode, " air quantity " is being set as in the automatic situation of air quantity, when upper and lower wind direction pattern switches to blowing up pattern from blowing down pattern, air quantity control part 162 is according to indoor temperature and design temperature, select the setting value corresponding with any one air quantity in air quantity H and air quantity M, airflow value is defined as to selected setting value, thereby adjusts air quantity.On the other hand, user, " operation mode " is set as heating, " upper and lower wind direction " is set as to wind direction automatic mode, " air quantity " is set as in the automatic situation of air quantity, when upper and lower wind direction pattern switches to blowing down pattern from blowing up pattern, air quantity control part 162 is according to indoor temperature and design temperature, select the setting value corresponding with air quantity H, air quantity M or air quantity L, airflow value is defined as to selected setting value, thereby adjusts air quantity.
Thus, in during execution blowing up pattern, be adjusted into air quantity more than air quantity M, so, can guarantee to form the needed minimum air quantity of circulating current, and, in during execution blowing down pattern, can be adjusted into the predetermined wind amount corresponding with indoor temperature and design temperature (air quantity H, air quantity M or air quantity L).
Like this, when upper and lower wind direction pattern is switched to blowing up pattern, adjust air quantity to guarantee to form the needed minimum air quantity of circulating current, so, can reduce cannot form due to deficiency in draught the possibility of circulating current.
In addition, when air quantity increases, the temperature of blow out air reduces, so, the in the situation that of being adjusted into air quantity increase when carrying out blowing up pattern, during with execution blowing down pattern, to compare, the temperature of blow out air reduces.In this situation, the temperature of the blow out air blowing out towards ceiling surface is lower than the temperature of the blow out air blowing out towards ground, so, can further reduce warm braw and be trapped near possibility ceiling.
In addition, adjusting air quantity can be while switching to blowing up pattern from blowing down pattern to guarantee to be used to form the timing of the minimum air quantity of circulating current,, when can be the rotation of horizontal baffle 31 and attached wall baffle plate 32, also can be from blowing down pattern switches to blowing up pattern, that is, after the rotation of horizontal baffle 31 and attached wall baffle plate 32 completes.In addition, if adjusting air quantity when blowing down pattern switches to blowing up pattern, blow out air may blow to user, so the timing of preferably adjusting air quantity is from blowing down pattern switches to blowing up pattern.
And, in this variation, with still irrelevant in not carrying out heat exchange state in carrying out heat exchange state, when upper and lower wind direction pattern switches to blowing up pattern, adjust air quantity to guarantee to form the needed minimum air quantity of circulating current.Thus, do not carrying out also can forming circulating current under heat exchange state.
(5-3) variation C
In the above-described embodiment, at " operation mode " for heat in the situation that, meet from the difference of indoor temperature and design temperature be below predetermined temperature through certain hour (the more than 0 minute scheduled time) more than, and from the operating frequency of compressor be preset frequency below through more than certain hour (the more than 0 minute scheduled time) the such the 1st switching condition while heating, with from switching to while not carrying out heat exchange state through any one condition in more than certain hour (the more than 0 minute scheduled time) the such the 2nd switching condition while heating by carrying out heat exchange state, from blowing down pattern, switch to blowing up pattern, meeting from switching to blowing up pattern through the scheduled time (being defaulted as 1 minute) during such the 3rd switching condition while heating, from blowing up pattern, switch to blowing down pattern.
But the indoor temperature while heating is sometimes subject to the impact of extraneous gas and changes.For example, in the situation that externally gas temperature is lower, due to the impact of extraneous gas, indoor temperature easily reduces.And warm braw has near the character being trapped in indoor ceiling, so in the situation that externally gas temperature is lower, the temperature of the air of Near Ground especially easily reduces.Therefore, in the situation that externally gas temperature is lower, when the temperature inequality in decontamination chamber, make blow out air when ceiling surface blows out, the air of indoor Near Ground can not warm energetically due to blow out air, the temperature of the air of indoor Near Ground sharply reduces, and may damage the comfortableness in indoor user.
Therefore, when the heating of above-mentioned embodiment, in switching condition, can also comprise the condition relevant with extraneous gas temperature.
For example, in the situation that the 1st switching condition and the 2nd while heating comprises extraneous gas temperature higher than the such condition of predetermined temperature in switching condition while heating, if extraneous gas temperature is below predetermined temperature, any one condition when not meeting the 1st switching condition and the 2nd while heating and heating in switching condition, even if " upper and lower wind direction " is set to wind direction automatic mode, can not switch to blowing up pattern from blowing down pattern yet.Consequently, horizontal baffle 31 and attached wall baffle plate 32 continue to take blowing down posture, so the air of Near Ground continues due to blow out air to warm energetically, can reduce the possibility that the impact due to extraneous gas sharply reduces the temperature of indoor Near Ground.
And, for example, the scheduled time of the 3rd switching condition while heating is according to extraneous gas temperature and stage ground is different, to be set as extraneous gas temperature lower the scheduled time is shorter in the situation that, even switch to blowing up pattern from blowing down pattern, also be that extraneous gas temperature is lower, the time of carrying out blowing up pattern is shorter.Consequently, the time that the air of Near Ground can not warm energetically by blow out air can be reduced, the possibility that the impact due to extraneous gas sharply reduces the temperature of indoor Near Ground can be reduced.
Like this, according to extraneous gas temperature, switch the posture of horizontal baffle 31 and attached wall baffle plate 32, thus, even be subject to the impact of extraneous gas temperature and under the situation that changes in indoor temperature, also can reduce to damage the possibility of user's comfortableness.
(5-4) variation D
In the above-described embodiment, during any one condition when meeting the 1st switching condition and the 2nd while heating and heat in switching condition, from blowing down pattern, switch to blowing up pattern.
Replace, also can from blowing down pattern, switch to blowing up pattern every the scheduled time.In this situation, when horizontal baffle 31 and attached wall baffle plate 32 take the state continuance of blowing down posture during the scheduled time, the posture of horizontal baffle 31 switches to level blowing posture from blowing down posture, the posture of attached wall baffle plate 32 switches to blowing up posture from blowing down posture, so, can towards ceiling surface, blow out blow out air every the scheduled time.
Thus, all air in teeter chamber termly, so the temperature in can decontamination chamber is uneven.
Utilizability in industry
The present invention is the invention relevant with the indoor apparatus of air conditioner that can eliminate the indoor temperature inequality while heating, is effectively applied to the indoor apparatus of air conditioner heating.
