Description

TECHNICAL FIELD The present invention is applied to an air conditioner or the like to realize comfortable air conditioning.

2. Description of the Related Art A conventional air blower with a deflection function of this type is shown in FIGS.
Shown in the figure. This is an example when applied to a buried air conditioner. In the figure, 1 is a blower, 2 is a flow outlet, 3 is a louver for deflecting the flow, 4 is a flow inlet, and 5 is a heat exchanger. By providing this, it functions as an air conditioner. In this configuration, the flow is sucked from the central suction port 4, passes through the heat exchanger 5 and exits from the plural outlets 2, and is deflected by the louver 3 at this time.

[Problems to be Solved by the Invention] However, in the above-mentioned configuration, since the outlets are arranged in plural, the flow from the fan is divided. As a result, the flow from each outlet has a small amount of momentum and a short reach of the jet flow, so that the air-conditioning flow cannot be sent to every corner of the room for comfortable air conditioning. .

The present invention solves the above-mentioned conventional problems, and makes it possible to blow out the flow from a fan from one outlet and to deflect it to a wide angle so that the air-conditioning flow reaches every corner of the room. The purpose is to make it possible to send and comfortably air-condition.

Means for Solving the Problems In order to solve the above problems, a blower device with a deflection function of the present invention is a fan that rotates around a main body axis and sends a flow, and a flow that guides the flow of the fan to the downstream and A guider having a throttle portion that narrows toward the main body axis, one nozzle that blows out the flow from the guider, and deflection means that deflects the flow from the nozzle are provided, and the deflection means are substantially parallel to each other. And a wall surface that forms a closed space of a shape that is arranged between the nozzles and the blade group, and that has an outer periphery that forms a circular shape having a larger diameter than the nozzle, and that is formed between the nozzles and the blade group. The vane group is arranged downstream of the nozzle substantially in parallel with the nozzle, and rotates about an axis of rotation that is oriented in a direction substantially perpendicular to the nozzle, and each of the vane groups constitutes the vane group. The root is configured so as to rotate about each blade axis and swing so that the inclination angle of the rotation axis with respect to the axial direction changes.

Action According to the present invention, with the above-described configuration, the flow blows out from one nozzle, and a sufficient reaching distance of the jet flow can be obtained by the accumulated momentum. As a result, the air-conditioning flow is sent to every corner of the room, enabling comfortable air conditioning.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.
In FIGS. 1 and 2, reference numeral 1 denotes a fan that rotates around the main body shaft 2 and is driven by a motor 3. Reference numeral 4 is an inlet of the fan, and 5 is an outlet. Reference numeral 6 is a guider for guiding the flow discharged from the fan to the downstream side, and has a throttle portion 7 for restricting the flow in the direction of the main body axis. Reference numeral 8 is one nozzle for blowing out the flow, and 9 is a deflecting means for deflecting the flow from the nozzle. The deflecting means 9 includes a plurality of blade groups 10 (each blade rotates about the blade axis 11 so that the tilt angle of the rotating shaft 13 oriented substantially in the same direction as the main body axis 2 with respect to the axial direction changes). The blade group 10 has a circular outer shape, is connected to a rotating shaft 13 by a supporting member 12, and is configured to rotate about the rotating shaft 13. Reference numeral 14 denotes a drive mechanism section, which is supported by the support shaft 15 by the idler 6 so that the rotary shaft 13 is rotated to rotate the entire blade group 10. Reference numeral 16 is a blade of the blade group 10. 17 is a ring mechanism for connecting the blades about the axis 11 so that they swing in the same way.
The swing angle of the blade group 10 is changed according to the movement of the outer shaft 18 in the rotation axis direction. ), And closed wall 19
(This connects the nozzle 8 and the blade group 10 to form a closed space. Further, it is formed in a gradually enlarged shape so as not to obstruct the flow even if the flow is deflected. The shape shown by the alternate long and short dash line may be used.). 20 is a flow suction port.

With the above configuration, the operation will be described below with reference to FIGS. 3 and 4. The flow entering through the suction port 20 and passing through the fan 1 is throttled toward the main body shaft 2 by the throttle 7 of the guider 6 and blown out from the nozzle 8. Further, in FIG. 3, the blade group 10 faces the direction of the rotation axis, so that the flow blows out as it is. Next, as shown in FIG. 4, the blade group 10 is tilted to the left. This is a result of the outer shaft 18 descending and the blade group 10 being tilted by the link 17. The inclination angle Q (see FIG. 4) is in the range of 0 ° to about 90 °, and it is not necessary to incline in the opposite direction. In this case, since the nozzle 8 is located downstream of the throttle and the diameter of the blade group 10 is formed larger than the diameter of the nozzle 8, the flow is deflected from the upstream side of the blade group 10 to the left side like F _1. , The blade group 10 largely deflects it to the left like F ₂ and blows it out. In this case, the air volume is deflected with almost no change from the case of FIG. Further, by rotating the rotary shaft 13, it becomes possible to send the flow in the entire circumferential direction at the deflection angle shown in FIG. As a result, by blowing all the air volume from one nozzle, the flow can be made distant and the flow can be sent in all arbitrary directions.

EFFECTS OF THE INVENTION As described above, according to the air blower with the deflection mechanism of the present invention, the following effects can be obtained.

(1) Since a guider having a throttle portion that restricts the flow from the fan, one nozzle that blows out the flow from the guider, and a deflection unit that deflects the flow from the nozzle are provided, one It is possible to send the flow to a wide range by obtaining a sufficient reaching distance of the jet flow by the momentum collected by blowing out all the flow from the nozzle.

(2) The deflecting means is arranged substantially parallel to each other and has a shape of a blade having an outer periphery which is a circle having a diameter larger than that of the nozzle, and a shape which is provided between the nozzle and the blade and does not hinder the flow from the nozzle And a wall forming a closed space of the blade, the blade group is disposed substantially parallel to the nozzle downstream of the nozzle, and rotates about a rotation axis oriented in a direction substantially perpendicular to the nozzle, and the blade group. Each of the blades that make up the blade rotates about the blade axis and swings so that the angle of inclination of the rotary shaft with respect to the axial direction changes, so that the jet flow has a wide angle without changing the air volume. It is possible to feed in the radial and circumferential directions.

(3) Due to the above effects, when the present invention is applied to an air conditioner, the flow can sufficiently reach an arbitrary position in a room to be air-conditioned, and comfortable air conditioning can be realized.
