[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wall-mounted air conditioner, and more particularly to a wind direction control technique and a wind direction display technique from an air outlet.
[0002]
[Prior art]
In general, a wall-mounted air conditioner is known in which a plurality of left and right flaps are provided at an air outlet of an air conditioner main body, and these left and right flaps are synchronized so that the wind direction can be controlled automatically or in a swing mode.
[0003]
In this type of product, assuming that the wall-mounted air conditioner body is conventionally installed at the approximate center of the conditioned room, the left and right flaps are synchronized and almost from the center of the air outlet. Generally, the wind direction is controlled by swinging within a predetermined swing width that is equally distributed to the left and right.
[0004]
[Problems to be solved by the invention]
However, in reality, the air conditioner main body is not necessarily installed in the approximate center of the conditioned room. Due to restrictions on the shape of the room to be conditioned, the air conditioner body may be installed at the right side of the room to be conditioned, or it may be installed at the left side. When the air conditioner body is installed at one side, if the wind direction is controlled by swinging within the specified swing width that is distributed almost evenly from the center of the air outlet, a part of the wind is wasted Therefore, there is a problem that warm air or cold air is not evenly distributed in the conditioned room and cannot reach every corner, and the conditioned room cannot be evenly air-conditioned.
[0005]
Conventionally, as a means for displaying the direction of the air flow from the air outlet, for example, a display for displaying the air current blown from the three directions of the substantially center, right side and left side of the air outlet has been proposed. .
[0006]
However, if the display number of the blowing direction can be increased with a simple configuration, the control direction of the blowing airflow can be finely notified to the user without increasing the cost of the product.
[0007]
Therefore, the object of the present invention is to solve the above-mentioned problems of the prior art, allow warm air or cold air to reach all over the room to be conditioned and finely control the direction of blown air flow to the user. An object of the present invention is to provide a wall-mounted air conditioner that can be notified.
[0008]
[Means for Solving the Problems]
The invention according to claim 1 is a wall-mounted air conditioner comprising a plurality of left and right flaps at the air outlet of the air conditioner main body, and the left and right flaps are synchronized so that the wind direction can be controlled automatically or in a swing mode. An installation position switch for outputting an installation position signal to the conditioned room of the air conditioner main body, and a control means for changing the swing width of the plurality of left and right flaps in the automatic or swing mode according to the installation position signal. When the air conditioner main body is installed at a substantially central portion of the conditioned room, the control means synchronizes a plurality of left and right flaps and extends from the center of the air outlet to the left and right positions evenly. When swinging within the distributed first swing width and the air conditioner body is installed on the right side of the conditioned room, Synchronize the right flap, reclassify the remaining third swing width excluding the right second swing width in the first swing width into the same number of positions as the position, and swing the air swing unit main body. Is installed on the left side of the conditioned room, a plurality of left and right flaps are synchronized, and the same number as the above positions in the remaining fifth swing width excluding the left fourth swing width in the first swing width. It is characterized by re-dividing into positions and swinging .
[0009]
According to a second aspect of the present invention, in the first aspect, the second swing width is substantially a quarter of the first swing width.
[0010]
According to a third aspect of the present invention, in the first aspect, the fourth swing width is substantially a quarter of the first swing width.

[0016]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0017]
FIG. 1 is a longitudinal sectional view of a wall-mounted air conditioner. Reference numeral 1 denotes an air conditioner main body, and the main body 1 is installed on a wall 3. An indoor heat exchanger 5 and a cross flow fan 7 are installed in the main body 1.
[0018]
An upper suction port 9 is integrally formed in a grill shape in the upper portion 1A of the main body 1, and the suction grill 11 has an upper end 11A at the front edge portion 1B of the upper portion 1A with a fulcrum not shown in the center. With the hinge connected, the lower end 11B is attached so as to be freely opened from the front surface of the air conditioner body 1.
[0019]
A suction filter 13 having a filter material is attached to the inside of the suction grill 11 so as to be movable up and down.
[0020]
An air outlet 21 surrounded by the scroll portion 17 and the tongue 19 is formed in the lower part of the air conditioner body 1, and a wind direction changing plate 23 is disposed in the air outlet 21. The wind direction changing plate 23 includes a lower horizontal plate 24 having a narrow width extending in the lower longitudinal direction of the air blowing port 21, an upper horizontal plate 25 extending in the upper longitudinal direction of the air blowing port 21, and an air blowing. A plurality of left and right flaps 26 extending in the short direction of the mouth 21 are provided. An ion generator 27 is attached to the narrowest upstream position in the air outlet 21.
[0021]
As shown in FIG. 2, the lower horizontal plate 24 is composed of a single narrow and narrow flap 24, and the upper horizontal plate 25 is wider than the lower horizontal plate 24 and is divided into two longitudinally divided plates. It consists of flaps 25A and 25B.
[0022]
Each of the flaps 24, 25A, 25B is connected to an independent DC stepping motor, and for example, as shown in FIG. 3, each of the flaps 24, 25A, 25B is configured to be capable of swing control up and down with their phases shifted independently. .
[0023]
As shown in FIG. 4, the plurality of left and right flaps 26 are rotatably mounted on a single elongated plate 34, and the left and right flaps 26 are connected to each other by respective bars 32. Of the left and right flaps 26 connected to each other, the left and right flaps 26A at the right end in the figure are connected to the drive shaft of a DC stepping motor (not shown), and the motor is rotated forward and reverse. The left and right flaps 26 are synchronously controlled in posture.
[0024]
By the way, as shown in FIG. 5, the air conditioner main body 1 is installed at the approximate center in the conditioned room 41 (air conditioner main body 1X), or is installed on the right side in the conditioned room 41 (air conditioner). The machine main body 1Y) is installed on the left side in the conditioned room 41 (air conditioner main body 1Z), and where it is installed in the conditioned room 41 varies depending on the installation conditions.
[0025]
In the present embodiment, the airflow Y blown from the air outlet 21 is unevenly distributed in the conditioned room 41 regardless of where the air conditioner main body 1 is installed in the approximate center, right side, left side, etc. of the conditioned room 41. However, the left and right flaps 26 are synchronously controlled so as to reach every corner.
[0026]
FIG. 6 shows a control flow.
[0027]
First, it is determined whether the operation is cooling or heating (S1). During the cooling operation, as shown in FIG. 7, the swing width W0 of the left and right flaps is corrected and controlled to be narrower than the swing width W1 during the heating operation (S2). However, the swing width W0 during the cooling operation varies depending on the model of the air conditioner.
[0028]
Regardless of the swing widths W0 and W1, as shown in FIG. 8A, the swing widths of the left and right flaps are divided into four equal parts, and the first swing width W1 (left and right equally distributed from the center of the air outlet 21). During the heating operation), five blowing positions C (1) to C (5) are set (S3).
[0029]
The five blowing positions C (1) to C (5) indicate the direction of the airflow. For example, in the position C (1), all the left and right flaps 26 are synchronized with each other in the direction indicated by C (1). The attitude is controlled substantially in parallel.
[0030]
Next, it is determined whether the automatic mode or the swing mode is set (S4). The swing mode is a mode in which all the left and right flaps 26 are synchronized and always swing in the horizontal direction without stopping. The automatic mode is a mode in which the swing is performed in the horizontal direction, but depending on the conditions on the air conditioner side. Is a mode including a stop operation.
[0031]
If the automatic or swing mode is set in S4, the installation position of the air conditioner body 1 is determined (S5).
[0032]
As shown in FIG. 5, this installation position is determined by distinguishing between the approximate center, the right side, and the left side of the conditioned room 41.
[0033]
For example, an installation switch (not shown) such as a dip switch that is switched according to the installation position is installed in the air conditioner body 1, and the installation switch or the like installs the installation switch according to the installation position of the air conditioner body 1. Is switched, an installation position signal is output from this, and it is determined from this signal whether it is approximately the center, right side, or left side of the conditioned room 41.
[0034]
When the installation position of the air conditioner main body 1 is substantially at the center of the conditioned room 41, the correction of each position shown in FIG. 8A is not performed (S6), and the five outlet positions C (1) to C (1) determined first. 5 ▼ is used as it is, and control according to this position is executed (S7). It should be noted that in S4, if it is not automatic or swing mode, it is manual, and in this case as well, each position shown in FIG. 8A is not corrected (S6), and the five determined outlet positions C (1) -C (5) is used as it is, and control according to this position is executed (S7).
[0035]
According to this, since all the left and right flaps 26 are swung within the first swing width W1 (during heating operation) shown in FIG. 8A that is equally distributed from the center of the air outlet 21 to the left and right, the conditioned air is not covered. Even in the harmony room 41, it is possible to reach every corner.
[0036]
When the installation position is on the right side of the conditioned room 41, correction of each position is performed as shown in FIG. 8B (S8).
[0037]
That is, the second swing width W2 on the right side in the first swing width W1 is masked, and the remaining third swing width W3 except for the same is divided into four equal parts. Two outlet positions R (1) to R (5) are set, and control according to these positions is executed (S9). The second swing width W2 is approximately ¼ of the first swing width W1.
[0038]
According to this, since all the left and right flaps 26 are swung within the third swing width W3, the conditioned air is not supplied to the masked second swing width W2, and is all leftward of the conditioned room 41. Since the air is supplied, the conditioned air can reach the conditioned room 41 evenly. Even if the masked second swing width W2 is too large or too small, unevenness of the conditioned air is generated. Here, since the second swing width W2 is set to a width that is approximately 1/4 of the first swing width W1, uniform air blowing is possible.
[0039]
When the installation position is on the left side of the conditioned room 41, correction of each position is performed as shown in FIG. 8C (S10).
[0040]
That is, the fourth swing width W4 on the left side in the first swing width W1 is masked, and the remaining fifth swing width W5, excluding the mask, is divided into four equal parts. Two outlet positions L (1) to L (5) are set, and control according to these positions is executed (S11). The fourth swing width W4 is approximately ¼ of the first swing width W1.
[0041]
According to this, since all the left and right flaps 26 are swung within the fifth swing width W5, the conditioned air is not supplied to the masked fourth swing width W4, and is all directed rightward of the conditioned room 41. Since the air is supplied, the conditioned air can reach the conditioned room 41 evenly. Even if the masked fourth swing width W4 is too large or too small, unevenness of the conditioned air is generated. Here, since the fourth swing width W4 is set to a width that is approximately ¼ of the first swing width W1, uniform air blowing is possible.
[0042]
FIG. 9 shows another embodiment.
[0043]
FIG. 9 shows a display device 31 that displays the flow direction of the airflow from the air outlet 21, and this display device 31 is attached to the longitudinal center of the front surface of the suction grille 11 (see FIG. 1). . The display device 31 includes a display unit (wind direction monitor) that displays a wind direction including a plurality of LED rows 31A to 31C, and a display unit (ion monitor) 31D that displays the generation of ions.
[0044]
This LED 31D also serves as a filter sign, and when the filter dirt is detected, the fact of the dirt is displayed, and thereafter, the generation of ions is not displayed until the filter dirt is removed.
[0045]
In this embodiment, each LED row 31A-31C points out the flow direction of the airflow from the air blowing outlet 21 in the swing width W1.
[0046]
As shown in FIG. 10, when an air flow is formed in a substantially central portion (region C) of the air outlet 21, the LED column (first means) 31 </ b> B in the central column is turned on, and the right side (region) of the air outlet 21. E) When the air flow is formed, the right column LED row (second means) 31C is turned on, and when the air flow is formed on the left side (region A) of the air outlet 21, the left column LED row (second row) (Third means) 31A is turned on.
[0047]
And in this embodiment, in addition to this, when an airflow is formed between the substantially central part and the right side of the air outlet 21 (area D), the LED column (first means) 31B in the central column and the right side When the vertical LED row (second means) 31C is lit and displayed in combination and an air flow is formed between the substantially central portion and the left side of the air outlet 21 (region B), the central vertical LED row ( The first means 31B and the left column LED row (third means) 31A are lit in a composite manner.
[0048]
According to this, it is possible to confirm in which direction the airflow is formed only by looking at the lighting states of the LED rows 31A to 31C.
[0049]
In addition, since the number of indications of the blowing direction can be increased from three directions to five directions (A to E) with a simple configuration, the control direction of the blowing airflow is finely notified to the user without increasing the cost of the product. be able to.
[0050]
Furthermore, when the wind speed from the air blowing port 21 changes, it can be notified to a user by changing the display form of each LED row 31A-31C. For example, as a display form showing the flow direction of the airflow, when a form in which the lighting of each LED row 31A to 31C is continuously turned on and off from the upper LED toward the lower LED is adopted, Form changes such as decreasing the amount of time shift as the wind speed increases are adopted.
[0051]
According to this, it is possible to easily check how much the air volume is by simply looking at the display form of each of the LED rows 31A to 31C.
[0052]
As mentioned above, although this invention was demonstrated based on one Embodiment, this invention is not limited to this. In the above-described embodiment, the description has been given taking five blowing positions as an example, but any number of positions may be used.
[0053]
