Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wind direction control method for controlling the direction of cold air blown out from the outlet of an air conditioner. The present invention relates to a method for controlling the wind direction of an air conditioner that cools the air and quickly makes the entire room comfortable.

[Conventional Example] Conventionally, in this type of air conditioner, the direction of the cold air blown is varied in order to rapidly cool a living space and make the entire room a comfortable environment. For this purpose, a single vertical wind direction plate is installed on the outlet side of the air conditioner, and this vertical wind direction plate can be rotated vertically to blow cold air directly onto the human body, which in turn cools the living space. After that, the upper and lower wind direction plates are rotated horizontally to ensure that the cool air is distributed throughout the room. However, when using the above-mentioned vertical wind direction plates, the wind direction is limited and it is difficult to equalize the temperature distribution throughout the room.

Therefore, for example, in addition to the above single vertical wind direction board, left and right wind direction boards are provided on the cold air outlet side, and these up and down wind direction boards are rotated horizontally and vertically, and the left and right wind direction boards are rotated left and right. A wind direction control method has been proposed in which the airflow is changed from side to side.

[Problem to be Solved by the Invention] By the way, in the above-mentioned wind direction control method, for example, at the start of cooling operation, one vertical wind direction plate is set downward, and cold air is blown directly onto the human body to rapidly cool the living space. When the indoor temperature reaches the set temperature, the upper and lower wind direction plates are rotated upward, and the left and right air direction plates are rotated in the left and right directions to cool the room without blowing cold air directly onto the human body. Trying to equalize the temperature.

However, the vertical wind direction plate and the left and right wind direction plate are controlled based on the indoor temperature, and since there is only one vertical wind direction plate, when the indoor temperature is high, the vertical wind direction plate remains facing downward for a long time. Therefore, depending on the indoor temperature, spots of cold air may be blown directly onto the human body for a long period of time, causing negative effects such as excessive cold on the human body, and furthermore, the indoor temperature may take a long time to equalize, until a comfortable environment is achieved. It may take some time.

This invention was made in view of the above problems, and its purpose is to
An object of the present invention is to provide a method for controlling the wind direction of an air conditioner, which can rapidly cool a living space and make the entire room a comfortable environment.

[Means for Solving the Problems] In order to achieve the above object, the method for controlling the wind direction of an air conditioner according to the present invention mainly includes a method for controlling the wind direction of an air conditioner, in which the air outlet is An air conditioner that is provided with a vertical wind direction control plate having a wind direction plate and a subwind direction plate, and a left and right wind direction control plate divided into two groups, the main wind direction plate and the subwind direction plate being arranged substantially horizontally and vertically, respectively. A vertical wind direction adjustment plate drive unit that rotates; a left and right wind direction adjustment plate drive unit that can rotate at least the left side wind direction plate group and the right side wind direction plate group of the left and right wind direction plates in opposite directions; and a cooling operation of the air conditioner. It has a timer section that operates at the time of start and measures a predetermined time, and a control section that controls the vertical wind direction adjustment plate drive section and the left and right wind direction adjustment plate drive section according to the elapsed time from the start of the cooling operation, When starting the cooling operation of the air conditioner, first set each of the wind direction plate groups of the left and right wind direction adjustment plates in a direction substantially parallel to the wind flow direction by the blower fan, set the main wind direction board in a substantially perpendicular direction, and set the sub wind direction board. Approximately horizontal direction, specified time (Ta) from the start of cooling operation
After the elapse of time, the right side wind direction plate group and the left side wind direction plate group of the left and right adjustment plates are turned outward, respectively, and after a further predetermined time (Tb) has elapsed after the above predetermined time (Ta) has elapsed, the main wind direction plate and the secondary wind direction of the vertical wind direction adjustment plate are changed. The gist is that the plates are integrally arranged in a substantially horizontal direction.

[Function] In the above method, when the air conditioner is set to the cooling mode, each of the wind direction plates of the left and right wind direction adjustment plates is initially set in a direction approximately parallel (center position) to the direction of the wind flow obtained at the indoor fan section. The main wind direction plate of the vertical wind direction adjustment plate is rotated in a substantially vertical direction, and the sub wind direction plate is rotated in a substantially horizontal direction. Then, as shown in FIG. 9, low-area cooling is achieved by double blow-off, and the cold air from the blow-off ports is blown directly onto the human body. This low area cooling is carried out for a predetermined period of time, for example 5 minutes, by a timer means, and then each of the wind direction plates of the left side wind direction plate group and the right side wind direction plate group are rotated in opposite outward directions. Then, as shown in FIG. 10, surround cooling is performed, and the cold air from the outlet is divided into left and right directions, reducing the amount of air blown directly onto the human body. In other words, for 5 minutes from the start of cooling operation, cold air is blown directly onto the human body by low area cooling, and then for 5 minutes, the direction of the cold air is changed by surround cooling to cover the entire room (including the human body), as well as the floor and Since wall cooling is performed, there is no negative effect such as excessive cooling on the human body, and the double blowout of the low area cooling mentioned above cools not only the lower part of the room but also the upper part to some extent. Therefore, the temperature in the indoor space can be uniformized more quickly.

In addition, when the living space is quickly cooled by the low area cooling followed by surround cooling without adversely affecting the human body, the main wind direction plate and the secondary wind direction plate are rotated as a unit in a substantially horizontal direction. . Then, as shown in FIG. 11, the entire room is cooled so that the cold air is distributed throughout the room.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

A left and right wind direction adjusting plate driving unit 13 is provided which can rotate the plate group 12a and the right side wind direction plate group 12b in opposite directions using a motor (not shown). In addition, the left and right wind direction adjustment plate drive unit 13
The number of motors can be one or two depending on the structure of the left and right wind direction adjustment plate 12.

Further, the indoor unit 1 is formed with an outlet 14 for blowing out cold air or warm air, and the indoor fan section 6 and the heat exchanger 15 are provided at the back of the outlet 14. The above-mentioned vertical wind direction adjusting plate 10 is provided on the exit side of the air passage including the blower fan portion 6, and the main wind direction plate 10a and the sub-wind direction plate 10b are configured to rotate horizontally or vertically, either integrally or individually. There is. Further, within the air outlet 14, the left and right air direction adjustment plates 12, which are divided into the two groups, are provided in the passage for the air flow obtained by the indoor fan section 6. The left side wind direction plate group 12a and the right side wind direction plate group 12b are each composed of a plurality of wind direction plates, and each group is adapted to rotate in an outward direction substantially parallel to the wind flow and opposite to each other.

On the other hand, the outdoor unit 16 includes an outdoor temperature sensor 17 that detects the outdoor temperature, an outdoor fan section 18 for a heat exchanger, and a four-way valve section 1 that is switched during cooling and heating.
9, an inverter section 20, a compressor 21 controlled by the inverter section 20, an outdoor control section (CPU) 22 for driving the compressor 21 based on control signals from the indoor unit 1, and the like are provided.

In the indoor unit 1, a remote control signal from the remote controller 4 or an operation panel (not shown) is transmitted to the indoor unit 1.
It determines the operation request based on the operation signal, calculates operating conditions suitable for the ambient environment such as indoor temperature, and outputs a power supply and a control signal of the calculated operating conditions to the outdoor unit 16. On the other hand, the outdoor unit 16 uses the control signal to decipher commands such as frequencies for cooling/heating operation and inverter control.
In addition to driving the outdoor fan section 18 and controlling switching of the four-way valve section 19, the compressor 2 is operated at the optimum frequency.
1 is controlled by an inverter.

Further, in accordance with the operation of the outdoor unit 16, in the indoor unit 1, the indoor fan section 6 is driven, the vertical wind direction adjusting plate drive section 11 rotates the vertical wind direction adjusting plate 10, and the left and right wind direction adjusting plate driving section 13
The left and right wind direction adjusting plate 12 is rotated, and cold air or warm air is blown into the room.

Next, the operation of the wind direction control method applied to the air conditioner having the above configuration will be explained based on the flowchart of FIG. 4 and the operation diagrams of FIGS. 4 to 11. It is assumed that the air conditioner is normally operated in cooling mode according to the temperature set by the remote controller 4 or the like. Also, with the start of cooling operation,
It is assumed that the timer of the timer section 9 is started.

First, when the cooling operation is started, as shown in FIG. A control signal is output to set the wind direction substantially parallel to the obtained wind flow direction (substantially at the center position), and each of the wind direction plates is rotated by the motor of the left and right wind direction adjustment plate driving section 13 (step ST1). Note that if each of the wind direction plates is already substantially parallel to the wind flow direction, the motor is not driven by the left and right wind direction adjusting plate driving section 13. Further, as shown in FIG. 7, from the indoor control unit 7, the main wind direction plate 10a of the vertical wind direction adjustment plate 10 is set in a substantially vertical direction (for example, about 90 degrees), and the sub wind direction board 10b is set in a substantially horizontal direction (for example, about 90 degrees). for example
30 to 45 degrees) is output, and the motor of the vertical wind direction adjustment plate drive unit 11 controls the main wind direction plates 1.
0a, the sub-wind direction plate 10b is rotated (step
ST2). Note that if the main wind direction plate 10a is already in the vertical direction, only the sub wind direction plate 10b is rotated. On the other hand, the outdoor control section 22 controls the outdoor fan section 18, the four-way valve section 19, and the inverter section 20, and the heat exchanger 15 of the indoor unit 1 constituting the refrigeration cycle including the compressor 21 receives The cooled air is blown out from the outlet 14 in the indoor fan section 6. At this time, the vertical wind direction adjustment plate 1
Due to the orientation of the main wind direction plate 10a and the sub wind direction plate 10b, the cold air from the air outlet 14 of the air conditioner is double blown downward throughout the room, as shown in FIG. That is, it is low area cooling, and the cold air is divided into upper and lower halves and blown directly onto the human body, providing a comfortable cooling sensation and quickly cooling the living space.

Subsequently, the indoor control unit 7 performs low area cooling and determines whether the timer time of the timer unit 9 has reached a predetermined value Ta (for example, 5 minutes) (step ST3). The low area cooling is for a predetermined period of time.
When only Ta is performed, as shown in Figure 6,
The indoor control unit 7 outputs a control signal that directs each of the wind direction plates of the left side wind direction plate group 12a and each of the wind direction plates of the right side wind direction plate group 12b to the outside in opposite directions, and the motor of the left and right wind direction adjustment plate drive unit 13 Each of these wind direction plates is rotated (step ST4). At this time, the vertical wind direction adjustment plate 10 remains double, and the 10th
As shown in the figure, the cold air from the air outlet 14 is blown out twice and divided into left and right directions. In other words, it is called surround cooling, and the cold air is blown not in spots but in a way that surrounds the human body, providing a comfortable feeling of cooling.In addition, it not only cools the living space, but also cools other parts of the room to some extent. In other words, the entire room can be cooled.

Subsequently, the indoor control unit 7 performs surround cooling and determines whether the timer time of the timer unit 9 has reached a predetermined value Tb (for example, 5 minutes) (step ST5). The surround cooling is for a predetermined time.
When only Tb is applied, as shown in Figure 8,
The indoor control unit 7 outputs a control signal that sets the main wind direction plate 10a and the subwind direction plate 10b of the vertical wind direction adjustment plate 10 in a substantially horizontal direction, and the main wind direction plate 10a and the subwind direction plate 10b are rotated (step ST6). In addition,
The rotation of the main wind direction plate 10a and the sub wind direction plate 10b is as follows.
Since the secondary wind direction plate 10b is already oriented in a substantially horizontal direction, the main wind direction plate 10a may be used alone, but depending on their structure, they may be formed integrally. At this time, each of the wind direction plates of the left side wind direction plate group 12a and each of the wind direction plates of the right side wind direction plate group 12b remain facing outward, as shown in FIG.
The cold air from the air outlet 14 is blown out throughout the room. That is, the entire room is cooled, and the entire room is made into a comfortable environment based on the set temperature.

In this way, at the start of cooling operation, the low-area cooling system blows cold air in the vertical direction directly onto the human body, and after a predetermined period of time (for example, 5 minutes) has elapsed, that is, before it has a negative impact on the human body,
It automatically switches to surround cooling and directs the cold air to surround the human body, cooling the entire room.
The living space is rapidly cooled in stages. Furthermore, following the low area cooling, surround cooling is performed for a predetermined period of time, and when the living space is cooled,
The system is automatically switched to the above-mentioned general cooling mode, and the cold air from the outlet 14 is blown out to the entire room, so that it is distributed throughout the room.

[Effects of the Invention] As explained above, according to the method for controlling the wind direction of an air conditioner of the present invention, the air outlet has a vertical wind direction adjusting plate including the main and auxiliary wind direction plates, and a left and right wind direction adjusting plate including a plurality of wind direction plates. and, until a predetermined time (Ta; for example, 5 minutes) has elapsed from the start of the cooling operation, the main wind direction plate is in the vertical direction, the secondary wind direction plate is in the horizontal direction, and the left and right wind direction adjustment plates are in the direction of the air flow by the indoor fan, The airflow is double-aired not only downward but also in the front direction (low area cooling), and the left side wind direction plate group of the left and right air direction control plates is installed until the specified time (Tb; for example, 5 minutes) has elapsed from after the same predetermined time (Ta). Then, the right side wind direction plates are set in opposite outward directions, and the cold air is blown out in a double direction and directed outward so as to surround the entire room (including the human body) (surround cooling), and after the specified time (Tb) has elapsed, the above The wind direction plate and the sub-wind direction plate are integrally oriented horizontally, and the cold air blown is directed toward the front side and outward so as to cover the entire room (total cooling). feet) as well as
The double blowout allows cold air to be applied to the entire human body, and after a predetermined period of time, surround cooling can be used to cool the entire room (including the human body), and the double blowout allows cooling to be applied to the entire room (including the human body). Since the air is blown in the lateral direction, the temperature distribution throughout the room can be made more uniform, and when the entire room is being cooled, the entire room can be kept in a comfortable environment. It has the useful effect of not having any adverse effects on the human body.
