Description

  The present invention relates to an air direction control device for an air outlet and an indoor unit of an air conditioner that includes an air direction plate that deflects an air flow discharged from the air outlet.

  When trying to deflect the blown air using a single wind direction plate, not only does the bending pressure loss of the air flow increase as the deflection angle increases, but also the pressure loss increases as the distance between the adjacent wind direction plates decreases. Increases and the air volume decreases. In order to suppress this, various proposals have been made.

  The blade body pivotally supported is divided into two in the front and rear direction along the air flow direction, and the divided portions are joined so as to be bent through a moderation mechanism, and the link mechanism is connected to one of the divided bodies as a drive source. There is known an air-conditioning blower blade structure in which the blade body can be automatically swung as a whole while the other divided body can be bent with a manual knob with respect to the other divided body ( For example, see Patent Document 1).

  Further, in the air conditioner wind direction changing device in which a plurality of louvers are arranged at predetermined intervals along a direction orthogonal to the blowing direction in the outlet, and an operating rod for connecting the louvers is provided. The louver has a front louver part and a rear louver part connected to each other via a hinge, each rear louver part is fixed to the outlet, and each front louver part is connected by an operating rod. Is known (for example, see Patent Document 2).

Furthermore, the vertical blades are attached to the outlet for changing the direction of the blown air, and a plurality of thick portions and a plurality of thin portions extending in the vertical direction are alternately arranged from the upstream side to the downstream side of the blown air. A vertical blade repeatedly provided is known (for example, see Patent Document 3).

  When the distance between the blower and the air outlet is long, and the air flow path of the air outlet is sufficiently secured, and the size of the inflow direction of the air direction plate that controls the airflow can be kept large, It is possible to configure in front and back instead of staggered, but if the distance between the blower and the air outlet is not sufficiently secured, the airflow direction dimension of the wind direction plate will be small, so the small wind direction plate will be When it divided | segmented by the side and arrange | positioned back and forth, there existed a subject that the blown-out air current did not bend.

  In addition, even if the wind direction plates are small, it is possible to deflect the air flow by narrowing the interval between the wind direction plates, but the pressure loss increases due to the increase in the number of wind direction plates, and the blowout air volume decreases and the fan efficiency There was a problem of energy saving deterioration due to deterioration of noise and increase in noise due to wind noise of wind direction plates.

  The present invention has been made in order to solve the above-described problems, and can smoothly deflect the airflow discharged from the blowout port, and even when the airflow is largely deflected, the pressure loss is small and the airflow is prevented from decreasing. It aims at providing the indoor unit of the air conditioner provided with the wind direction control apparatus of an exit, and the wind direction control apparatus of the blower outlet.

  An air outlet direction control device according to the present invention is provided in an air outlet that blows out wind generated by driving a blower, and is provided in the air outlet in an air outlet direction control device that controls the direction of the air that is blown out. One wind direction plate that has a windward wind direction plate and a windward side wind direction plate arranged in a staggered pattern, and is substantially continuous between the windward wind direction plate and the windward side wind direction plate when deflecting the wind blown from the outlet. The windward wind direction plate and the leeward wind direction plate are fixed to a pedestal that rotates in the airflow control direction at the air outlet, and the pedestal is rotatably attached to the air passage wall of the air outlet.

  Since the air direction control device for the air outlet according to the present invention is configured as described above, the air flow discharged from the air outlet can be smoothly deflected, so that even when the air is largely deflected, the pressure loss is small and the air volume is reduced. It is possible to control and save energy and improve comfort.

FIGS. 1 to 9 are diagrams showing Embodiment 1, FIG. 1 is a cross-sectional view of an indoor unit of an air conditioner, FIG. 2 is a blower outlet structure diagram in the case of flowing a straight air flow, and FIG. 3 is a case of flowing a straight air flow 4 is a partially enlarged view of the air outlet, FIG. 4 is a structural view of the air outlet when the air flow is flown in the left direction, FIG. 5 is an enlarged view of the air outlet when the air flow is flowed in the left direction, and FIG. FIG. 7 is a view showing the outlet fixed to the pedestal, FIG. 7 is a view showing the relationship between the wind direction deflection angle and the pressure loss of the air conditioner using the wind direction plate, and FIG. 8 is the wind direction deflection angle of the air conditioner using the wind direction plate. FIG. 9 is a diagram showing the air flow distribution of an air conditioner using a wind direction plate.

  As shown in FIG. 1, the indoor unit 10 of an air conditioner has a blower 15 inside, and a heat exchanger 14 of a refrigeration cycle is provided on the front and back surfaces so as to surround the blower 15. By operating the blower 15, the indoor air enters the interior of the air conditioner indoor unit 10 through the suction port 11, dust is first removed by the air filter 12, and then a part of the air is purified by the air purifier 13. It is cleaned with. And the air which passed the air purifier 13 is guide | induced to the heat exchanger 14, and heat-exchanges with the refrigerant | coolant of a refrigerating cycle here. The conditioned air is blown to the air outlet 16 and is composed of an upwind wind direction plate 1 and a leeward wind direction plate 2 fixed to the pedestal 7 attached to the up and down wind direction plate 6 and the air passage wall 17 of the air outlet 16. The wind direction is controlled by the wind direction plate and blown out into the room.

  The air outlet direction control device of the present embodiment is a device that is provided in the air outlet 16 that blows out the wind generated by driving the blower 15 and controls the direction of the air that is blown out, and is provided in the air outlet 16. When the windward wind direction plate 1 and the leeward wind direction plate 1 arranged in a staggered manner are deflected and the wind blown from the air outlet 16 is deflected, the windward wind direction plate 1 and the leeward wind direction plate 2 are substantially continuous. The leeward wind direction plate 1 and the leeward side wind direction plate 2 are fixed to a pedestal 7 that rotates in the airflow control direction at the air outlet 16, and the pedestal 7 rotates on the air passage wall 17 of the air outlet 16. It is attached freely.

  In this embodiment, as shown in FIGS. 2 and 3, the left and right wind direction plates are divided into an upwind wind direction plate 1 and a leeward wind direction plate 2, and the upwind wind direction plate 1 and the leeward wind direction plate 2 are alternately arranged. It is characterized by being arranged in a staggered pattern. The windward side wind direction plate 1 and the leeward side wind direction plate 2 each have a plurality of wind direction plates, and the plurality of wind direction plates are linked and interlocked. In the example of FIGS. 2 and 3, the windward wind direction plate 1 and the leeward wind direction plate 2 are arranged in parallel, and the airflow from the air outlet 16 is made to travel straight without being deflected. Airflow flows between the plate 1 and the leeward wind direction plate 2.

  The example of FIGS. 4 and 5 is a case of deflecting the blown airflow from the air outlet 16, and the windward wind direction plate 1 and the leeward side wind direction plate 2 move in conjunction with each other to form a pseudo arcuate wind direction plate. However, even if it is not a pseudo arc shape, it is only necessary to form almost one wind direction plate as if it were continuous. 4 and 5 show an example in which the blown air is deflected from the outlet 16 to the left side. However, since the windward wind direction plate 1 and the leeward side wind direction plate 2 are arranged in a staggered manner, not only the left side but also the right side. Similarly, it can be deflected.

At this time, the deflection angle of the wind direction plate is
Leeward deflection angle theta ₂ of the wind direction plate _2> deflection angle theta ₁ of the windward-side louver 1
As a result, the airflow blown from the blower 15 is not deflected at a sharp angle, but the airflow is smoothly deflected by gradually deflecting the airflow, and the pressure loss generated when the airflow is deflected is increased. Can be suppressed.

Also, the length of the wind direction plate in the flow direction
The length L1 in the flow direction of the leeward wind direction plate 1> the length L2 in the flow direction of the leeward side wind direction plate 2
By doing, since the distance which passes the leeward side wind direction board 2 part with the narrow space | interval L of a wind direction board becomes short, the increase in a pressure loss can be suppressed.

  When the distance between the blower 15 and the air outlet 16 is not sufficiently secured, the air passage length A (see FIG. 1) of the air outlet 16 is also shortened, and the airflow direction dimension of the wind direction plate cannot be sufficiently secured. When the wind direction plate is divided into the windward side wind direction plate 1 and the leeward side wind direction plate 2 and arranged in a staggered manner, when the airflow blown from the outlet 16 is deflected to the left and right, the wind direction plate is as if it is one large dummy. It can be set as the wind direction board used as circular arc shape.

  Further, as shown in FIG. 6, a rotation shaft 8 fixed to the wind path wall 17 of the air outlet 16 is provided, and a substantially central portion of the pedestal 7 to which the windward wind direction plate 1 and the leeward side wind direction plate 2 are fixed is disposed on the rotation shaft 8. And the pedestal 7 is rotated in the airflow control direction, so that the blown airflow can be smoothly deflected without reducing the distance L between the wind direction plates (particularly, the distance between the leeward wind direction plates 2 having a narrow interval). . 6A shows the case where the pedestal 7 is not rotated, FIG. 6B shows the case where the pedestal 7 is rotated counterclockwise to deflect the air flow to the left side, and FIG. 6C shows that the pedestal 7 is rotated clockwise. In this case, the airflow is deflected to the right. The rotating shaft 8 may be fixed to the base 7 and a fitting hole for fitting the rotating shaft 8 may be provided in the air passage wall 17. Moreover, B of FIG. 6 shows the length of the flow direction of the blower outlet 16. FIG.

  As described above, when the distance between the conventional blower 15 and the air outlet 16 is not sufficiently secured, the size of the wind direction plate is reduced in the airflow direction. However, there is a problem that the airflow is not deflected. However, by making the wind direction plate into one large pseudo arc shape and making the pedestal 7 that fixes the wind direction plate rotatable, as shown in FIG. The pressure loss that occurs when the airflow is deflected against the wind direction plate can be reduced, and as a result, as shown in FIGS. 8 and 9, the wind reaches farther than when considered with the same right and left wind direction deflection angle α. Can do. FIG. 9 is a comparison of the airflow distribution when the room is viewed from above with the prior art and the present invention (fixing the base 7 and rotating the base 7). FIG. 9A shows the case where the right and left wind direction deflection angle α is about 70 °. Compared to the conventional air flow distribution indicated by the dotted line, the air flow distribution when the pedestal 7 of the present invention indicated by the two-dot chain line is fixed widens, and further, the air flow distribution when the pedestal 7 of the present invention indicated by the solid line is movable further expands. . FIG. 9B shows a case where the left and right wind direction deflection angle α is about 50 °. By making the pedestal 7 for fixing the wind direction plate rotatable, it is possible to deliver a wider range of the air flow blown out from the indoor unit 10 of the air conditioner, so that temperature unevenness in the living space can be eliminated and low noise can be achieved. Thus, a comfortable living space can be formed even in a large living room.

  In the above description, the left and right wind direction plates provided at the air outlet 16 of the indoor unit 10 of the air conditioner are divided and arranged in a staggered manner, but the present invention is not limited to the left and right wind direction plates. You may apply to an up-and-down wind direction board, and may apply to the wind direction board which blows off in one arbitrary direction.

  Although the air conditioner indoor unit 10 has been described above as an example, the air direction control device for the air outlet of the present embodiment is, for example, an air purifier, a car air conditioner, a duct air outlet, a ventilation device other than the air conditioner. It can be applied to electric fans.

Embodiment 2. FIG.
FIGS. 10 and 11 are views showing the second embodiment. FIG. 10 is a blower outlet structure diagram in which the pedestal is divided into two parts, and FIG. 11 is a blower hole structure diagram in which the pedestal is divided into four parts.
As shown in FIG. 10, the windward wind direction plate 1 and the leeward wind direction plate 2 for controlling the wind direction are arranged and fixed in a zigzag manner on a pedestal 7a and a pedestal 7b which are divided into two. The pedestal 7a and the pedestal 7b have a rotating shaft 8a and a rotating shaft 8b at their ends. The pedestal 7a rotates about the rotating shaft 8a counterclockwise when deflecting the airflow (FIG. 10B). The pedestal 7b rotates about the rotation axis 8b in the clockwise direction when deflecting the airflow (FIG. 10C).

  Moreover, as shown in FIG. 11, you may divide a base into four. The windward side wind direction plate 1 and the leeward side wind direction plate 2 for controlling the wind direction are arranged and fixed in a zigzag manner on the four divided bases 7a, 7b, 7c, 7d. The ends of the pedestal 7a, the pedestal 7b, the pedestal 7c, and the pedestal 7d are fitted to the rotary shaft 8a, the rotary shaft 8b, the rotary shaft 8c, and the rotary shaft 8d that are fixed to the air passage wall 17 of the air outlet 16. . The pedestal 7a and the pedestal 7b rotate about the rotating shaft 8a and the rotating shaft 8b, respectively, in the counterclockwise direction when deflecting the airflow (FIG. 11 (b)). Further, the pedestal 7c and the pedestal 7d rotate in the clockwise direction when the airflow is deflected around the rotation shaft 8c and the rotation shaft 8d, respectively (FIG. 11C).

Next, the operation will be described.
In the wind direction plate configured in this way, the distance between the blower 15 and the air outlet 16 is not sufficiently secured, the air path length A (see FIG. 1) of the air outlet 16 is shortened, and the air flow direction dimension of the air direction plate is reduced. Even when the airflow is blown left and right by dividing the windward wind direction plate 1 and the leeward wind direction plate 2 and arranging them in a zigzag pattern even in a configuration in which the wind direction plate cannot be sufficiently secured, the wind direction plate is as if It can be set as a wind direction plate having a large pseudo arc shape.

  Further, as shown in FIGS. 10 and 11, the problem that the distance L between the wind direction plates becomes narrower as the angle of the wind direction plate is increased. The pedestal 7 a, pedestal 7 b, 7c and pedestal 7d are provided with a rotatable rotating shaft 8a, rotating shaft 8b, rotating shaft 8c, and rotating shaft 8d at their ends, and the pedestal 7a, pedestal 7b, pedestal 7c, and pedestal 7d are rotated in the blowing direction. The blown airflow can be smoothly deflected without narrowing the gap L between the wind direction plates.

  Moreover, since the length B in the flow direction of the outlet 16 can be reduced by dividing the base into a plurality of parts, {B (no division)> Ba (two divisions)> Bb (four divisions)}, blower The airflow length A of the air outlet 16 is also shortened and the airflow direction dimension of the airflow direction plate cannot be sufficiently secured, so that the airflow can be smoothly deflected. Can do.

  As described above, conventionally, when the distance between the blower 15 and the outlet 16 is not sufficiently secured, the size in the airflow direction of the wind direction plate becomes small, so the reduced wind direction plate is divided on the windward side and the leeward side. In some cases, there was a problem that the blown airflow would not bend, but by making the wind direction plate a large pseudo arc shape and making the pedestal rotatable, as shown in FIG. 7, compared to the conventional one wind direction plate As a result, the pressure loss generated when the airflow is deflected can be reduced, and as a result, the wind can reach farther than the case where the same deflection angle is considered as shown in FIGS. In this way, it is possible to deliver a wider range of the airflow blown out from the air conditioner, so that it is possible to eliminate temperature unevenness in the living space, and to reduce noise and form a comfortable living space even in a large living room. It becomes possible.

As shown in FIG. 12, a vertical air direction plate that controls the vertical direction of the blown airflow is provided at the air outlet 16 of the indoor unit 10 of the air conditioner. The up / down wind direction plate is divided into a right up / down wind direction plate 6a and a left up / down wind direction plate 6b. The left and right wind direction plates of the first embodiment or the second embodiment and the upper and lower wind direction plates are combined.

Next, the operation will be described.
In the longitudinal direction of the indoor unit 10 of the air conditioner, the vertical wind direction plate configured as described above is divided into a vertical wind direction plate 6a on the right side and a vertical wind direction plate 6b on the left side to control the horizontal wind direction of the first embodiment. Similarly, the left and right wind direction plates are divided in the longitudinal direction, and the divided wind direction plates can be operated independently, so that it is possible to blow air currents in various wind directions.

  For example, although the shape of the room differs depending on the user, it is possible to blow out airflows that are in different room shapes. When a person on the right side of the indoor unit 10 of the air conditioner wants to hit the wind, the left up / down wind direction plate 6b faces upward and the right up / down wind direction plate 6a blows down, so that the indoor unit of the air conditioner 10 different left and right airflows can be delivered, and by incorporating the left and right wind direction plates of Embodiment 1 or 2 in the left and right direction, it becomes possible to deliver airflows over a wide range, so many people are comfortable It is possible to provide an indoor space where people can spend time.
