JP4331157B2 - Air outlet direction control device and air conditioner indoor unit - Google Patents

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 bend the blown air using a single wind direction plate, not only will the bending pressure loss of the air flow increase as the bending angle increases, but also the pressure loss will decrease as the distance between the adjacent wind direction plates becomes narrower. 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 to solve the above-described problems, and can smoothly deflect the airflow discharged from the air outlet, and even when the airflow is largely deflected, the pressure loss is small and the decrease in the airflow is suppressed. It aims at providing the indoor unit of the air conditioner provided with the wind direction control apparatus of a blower outlet, 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. When there is an upwind wind direction plate and a leeward side wind direction plate arranged in a staggered pattern, and the wind blown from the outlet is deflected, one wind direction plate that is almost continuous between the upwind direction plate and the leeward side wind direction plate It is characterized by forming.

  Since the airflow direction control device for the air outlet according to the present invention is configured as described above, the airflow discharged from the air outlet can be smoothly deflected, so that even when the airflow 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.

FIG. 7 is a diagram showing the relationship between the wind direction deflection angle and the pressure loss, FIG. 7 is a diagram showing the relationship between the wind direction deflection angle and the air flow arrival distance of the air conditioner using the wind direction plate, and FIG. 8 is the air conditioning using the wind direction plate. It is the figure which showed the airflow distribution of the machine.

  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 blown into the room with the wind direction controlled by the left and right wind direction plates composed of the windward wind direction plate 1 and the leeward wind direction plate 2 fixed to the vertical wind direction plate 6 and the pedestal 7. The

  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 windward side wind direction plate 2 are arranged in a staggered manner and the wind blown from the air outlet 16 is deflected, the windward wind direction plate 1 and the windward side wind direction plate 2 are substantially continuous. One wind direction plate is formed.

  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 one wind direction plate that is almost 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 air flow blown from the blower 15 is not deflected at a sharp angle, but the air flow is smoothly deflected by gradually deflecting the air flow, and an increase in pressure loss caused when the air flow is deflected is increased. Can be suppressed.

Also, the length of the wind direction plate in the flow direction
Since the length in the flow direction of the leeward wind direction plate 1> the length in the flow direction of the leeward wind direction plate 2, the distance passing through the portion of the leeward wind direction plate 2 having a narrow space L between the wind direction plates is reduced. Increase in 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 zigzag pattern, when the air flow blown from the outlet 16 is deflected left and right, the wind direction plate is almost as large as one sheet. A wind direction plate having a pseudo arc shape can be obtained.

  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, when the air flow is deflected with respect to one conventional wind direction plate as shown in FIG. 6, it is caused by making the wind direction plate one large pseudo arc shape. The pressure loss can be reduced, and as a result, the wind can reach farther when considered at the same deflection angle as shown in FIGS. As described above, since the airflow blown from the indoor unit 10 of the air conditioner can be delivered to a wider range, the temperature unevenness of the living space can be eliminated, the noise can be reduced, and a comfortable living space can be provided even in a large living room. It becomes possible to form.

  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.

The left and right wind direction plates of the first embodiment and the up and down 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 in this way 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. The left and right wind direction plates are divided into two in the longitudinal direction in the same manner as the upper and lower wind direction plates, and the divided wind direction plates can operate 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. Further, 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 room of the air conditioner The interior space where many people can spend comfortably because different airflows can be delivered on the left and right sides of the machine 10 and the airflow can be delivered over a wide area by incorporating the left and right wind direction plates of Embodiment 1 in the left and right directions.
