DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD OF THE INVENTION

The present invention relates to an air outlet device of an air conditioner which is disposed on a ceiling and blows conditioned air into a room.

[0002]

2. Description of the Related Art In an air conditioner, there is a conventional air outlet device disclosed in Japanese Utility Model Laid-Open No. 5-32943, which blows out and sends conditioned air sent through a duct into a room. Shown in FIG. 9 is a schematic diagram illustrating the configuration of a conventional outlet device.

In FIG. 9, a conventional outlet device 100 is
A plurality of blowout holes 101a are formed, and a panel 101 installed on the ceiling 10, a blowout chamber 2 connected to the air-conditioning duct 11 and arranged on the back side of the panel 101, and a blowout hole 101a of the panel 101 are formed. Ventilation holes 102 at the same interval
a, a shutter 102 slidably disposed on the back surface of the panel 101, and an actuator 5 for sliding the shutter 102.
The configuration is such that the opening area of 01a is adjusted to be large during cooling and small during heating.

In the conventional outlet device 100 having the above-described configuration, the shutter 102 is slid by the action of the actuator 5 to adjust the degree of communication between the outlet hole 101a of the panel 101 and the ventilation hole 102a of the shutter 102, thereby reducing the opening area. Determine the size. Air outlet 10 for cooling
The blowing speed is reduced by increasing the opening area of 1a, and the cooled and heavy air is slowly blown out and dispersed in the room. On the other hand, in the case of heating, on the other hand, the opening area of the blowout hole 101a is reduced to increase the blowout speed, and the warmed and lightened air is blown out strongly to reach the lower part of the room.

[0005] In addition to the above, there is a conventional outlet device shown in FIG. FIG. 10 is a schematic diagram illustrating the configuration of another conventional outlet device. In FIG. 10, the conventional outlet device 200 is formed as an anemo-type outlet in which a plurality of blades 202 are disposed inside an opening frame 201, and a heating element 203 is provided on the back side of the opening frame 201.
Is arranged. The heating element 203 is controlled via a power supply control unit 204 to generate heat to a predetermined temperature.

In this conventional outlet device 200, since the opening frame 201 is heated by the heating element 203, it is not cooled to a predetermined value or more by the blown cool air. Since the temperature of the opening frame 201 does not become lower than the predetermined temperature due to the heating of the heating element 203, even if the warm air in the room is attracted by the blown cool air and comes into contact with the opening frame 201, the dew condensation on the opening frame 201 occurs. Does not occur.

[0007]

Among the conventional blow-out devices configured as described above, in the former, the panel 101 and the shutter 102 require a portion for closing the blow-out hole 101a and the ventilation hole 102a. , Outlet 10
1a The sum of the opening areas is the outlet opening 2 of the outlet chamber 2.
There is a problem that the opening area from which the conditioned air actually blows is small, which is about half the area a, and the resistance when the conditioned air passes is large. In addition, since the opening area is small, there is a large amount of conditioned air per unit area passing through each of the blowout holes 101a, and the flow velocity at the time of the passage is increased to generate a large wind noise. Furthermore, since the wind pressure in the outlet chamber 2 is applied to the shutter 102 from the front, there is a problem that the sliding resistance of the shutter 102 is large and the shutter 102 must be slid with a large torque.

In the latter conventional outlet device,
The heating element 203 disposed on the back side of the opening frame 201 requires a power supply control unit 204, a power supply wiring, and the like, which complicates the apparatus itself, complicates the manufacturing process, and increases the manufacturing cost and running cost. There is a problem that. In particular, when air is conditioned by supplying cold air, the heating element 20 is used.
3, since the opening frame 201 is always warmed, there is a problem that the cooling function is hindered.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has an effect that the ratio of the area of the opening through which the conditioned air is actually blown to the blowout opening of the blowout chamber is increased, so that the passage resistance and the wind noise are reduced. It is an object of the present invention to provide an air outlet device which is small, can adjust the air volume with a small torque, can prevent dew condensation with a simple structure, and does not hinder the cooling function.

BEST MODE FOR CARRYING OUT THE INVENTION

(First Embodiment of the Present Invention) Hereinafter, an outlet device according to a first embodiment of the present invention will be described with reference to FIGS. 1 is a schematic configuration diagram of the outlet device according to the present embodiment, FIG. 2 is a longitudinal sectional view of the outlet device according to the present embodiment, and FIG. 3 is a cross-sectional view of the outlet device according to the present embodiment. Figure,
FIG. 4 is an explanatory view of a ceiling arrangement state of the outlet device according to the present embodiment.

As shown in the figures, the outlet device 1 according to the present embodiment has a relatively high ceiling 1 for air conditioning.
A rectangular outlet chamber 2 which is disposed in the ceiling 10 of a room where the air outlet is high with the blowout opening 2a facing downward and is supplied with conditioned air from the air conditioning duct 11, and a plate bent into a substantially V-shaped cross section. A plurality of openings 3a are formed in the plate-shaped body at equal intervals, and both side portions of the plate-shaped body are fixed to the inner side wall of the outlet chamber 2, and the plate-shaped body is formed in the outlet chamber 2. And a plate-shaped body having a surface shape substantially conforming to the plate-shaped body of the substrate part 3 provided with the V-shaped central bent protrusion portion facing the blowout opening 2a side. An opening 4a is formed, and an adjusting plate 4 slidably disposed above the substrate 3 and a movable portion made of a shape memory alloy that expands and contracts according to the temperature of the conditioned air. 3 and an actuator 5 disposed over the adjustment plate portion 4. Each opening hole of the plate portion 3 and the adjusting plate 4 3
The configuration is such that the opening area where a and 4a communicate is adjusted to be large during cooling and small during heating, and the amount of air blown into the room is controlled.

Next, the air blowing operation of the present embodiment based on the above configuration will be described. In the case of cooling, when cool air sent from the air conditioning duct 11 enters the outlet chamber 2,
The actuator 5 is acted upon by the cool air, and the adjusting plate 4 is moved to fully open each opening 3a. The cool air is blown out from each opening 3a while flowing toward the center of the blowing opening 2a along the V-shaped substrate 3, and flows down into the room from the center of the blowing opening 2a. The flow of the cool air as the primary air A flowing downward from the center of the outlet 2a toward the inside of the room attracts the air in the room, and an induced air flow is generated. In particular, the indoor air near the ceiling 10 is drawn as secondary air B from the edge of the blow-out opening 2a to the bottom of the substrate portion 3 in the blow-out chamber 2 along with the blowing of the cool air of the primary air A from the opening 3a. . The secondary air B in the room that has entered the outlet chamber 2 comes into contact with the cool air as the primary air A immediately after leaving the opening 3a, and is blown out from the center of the outlet 2a while mixing. The cool air of the primary air A flows downward while gathering at the center of the blowout opening 2a,
If the secondary air B in the room is drawn into the outlet chamber 2 and an air wall is formed between the edge of the outlet opening 2a and the cool air of the primary air A, the outlet opening 2a and its surroundings are cold. In addition, even if the drawn warm secondary air B comes into contact with the blowout opening 2 and its peripheral portion, no dew condensation occurs. By increasing the opening area of the opening 3a, the blowing speed of the cool air is reduced, and the cool air that is heavier than the room air is blown out slowly and diffused into the room in the region sufficiently widened from the high ceiling 10 to the floor surface. In addition, since the cool air attracts air near the ceiling 10 which is relatively warm and exits the outlet 2a while mixing with the air, the cooling effect of the indoor air is large and the room can be cooled in a short time. . The air blown out from the blow-out opening 2a is also slightly cooler than room temperature by mixing with air, and the person underneath does not feel too cold.

On the other hand, in the case of heating, when warm air of the primary air A sent from the air conditioning duct 11 enters the outlet chamber 2, the actuator 5 is acted upon the warm air, and the adjusting plate 4 is moved. Each opening 3a is slightly opened. 1
While the warm air of the next air A flows toward the center of the blowout opening 2a along the substrate portion 3, it blows out from each opening 3a and flows down into the room from the center of the blowout opening 2a. The flow of warm air of the primary air A flowing downward from the center of the blowout opening 2a into the room attracts the room air as the secondary air B, and an induced airflow is generated.
In particular, in the room air near the ceiling 10, the secondary air B is drawn from the edge of the blow-out opening 2 a below the substrate portion 3 in the blow-out chamber 2 with the warm air of the primary air A blowing from the opening 3 a. You. The secondary air B in the room that has entered the outlet chamber 2 is
It touches the warm air of the primary air A immediately after leaving the opening 3a, and exits from the center of the blowing opening 2a while mixing. By reducing the opening area of the opening 3a, the blowing speed of the warm air as the primary air A is increased, and the warm air, which is lighter than the room air, can reliably reach the floor from the high ceiling 10 and the primary air. The warm air as the air A attracts room air having a lower temperature as the secondary air B, and exits from the blow-out opening 2a while mixing with the secondary air B, so that heat transfer to the room air is promoted, and The effect of raising the temperature is great, and the room can be warmed in a short time.

In the outlet device according to the present embodiment, the conditioned air is collected at the center of the outlet 2a and blown out,
Since the indoor air is drawn into the outlet chamber 2 and flows down into the room while mixing the conditioned air with the air, the indoor air conditioning effect is large, air conditioning can be performed efficiently in a short time, and the air is blown out during cooling. Dew condensation around the opening 2a can be prevented.

In the above-described embodiment, a configuration is provided in which the rectangular outlet chamber 2, the substrate portion 3 made of a plate-like body having a substantially V-shaped cross section, and the adjusting plate portion 4 are shown in FIG. 5. Thus, a substantially cylindrical outlet chamber 2 and a conical body having a substantially V-shaped cross section are provided. A plurality of openings 3a are formed in the outer periphery of the conical body at equal intervals. A substrate portion 3 fixed to the inner side wall of the chamber 2 and disposed with the central protruding portion of the cone in the outlet chamber 2 toward the blowout opening 2a, and a surface shape substantially conforming to the conical shape of the substrate portion 3 A plurality of opening holes 4a are formed in the outer periphery of the cone, and an adjusting plate portion 4 rotatably disposed along the upper side of the substrate portion 3; And an actuator 5 which is disposed so as to be straddled. Each opening hole of the plate portion 3 and the adjusting plate 4 3
a, 4a may be configured to control the amount of air blown into the room by adjusting the opening area communicating therewith. In this configuration,
Since the opening 3a is oriented in any direction of 360 °, the conditioned air can be supplied to the room from the outlet 2a without bias.

FIG. 6 is a longitudinal sectional view of the outlet device according to the present embodiment. As shown in FIG. 6, the outlet device according to the present embodiment is different from the substrate unit 3 according to the first embodiment.
Instead, the V-shape of the substrate portion 3 is turned upside down, and both side portions of the plate-shaped body bent into a substantially V-shaped cross section are fixed to the vicinity of the blow-out opening 2a of the outlet chamber 2 and It is provided with a substrate portion 3 provided with a V-shaped central bent protruding portion protruding to the back side of the outlet chamber 2, and is provided in a room with a low ceiling 10.

Next, the air blowing operation of the present embodiment based on the above configuration will be described. In the case of cooling, when the primary air C cool air sent from the air conditioning duct 11 enters the outlet chamber 2, the actuator 5 is acted upon the cool air and moves the adjusting plate portion 4 to fully open each opening 3 a. To
The cool air of the primary air C blows out from each opening 3a while flowing toward the side of the blowing opening 2a along the substrate portion 3, and flows down into the room from the edge of the blowing opening 2a. The flow of the cool air of the primary air C spreading downward from the room while spreading from the blowing opening 2a attracts the room air as the secondary air D, and the mixing is promoted. By blowing the cool air of the primary air C from the outlet 2a to a wide area in the room, even when the ceiling 10 is low and the cool air heavier than the room air easily reaches the floor immediately, the cool air is blown into the wide area in the room. Is reached. Furthermore, the opening hole 3
By increasing the opening area of “a”, the cooling air blowing speed of the primary air C is reduced, and the cooling air is blown out slowly and is surely diffused into the indoor air. Can be cooled.

On the other hand, when the primary air C sent from the air-conditioning duct 11 is for heating, when the warm air sent from the air-conditioning duct 11 enters the outlet chamber 2, the actuator 5 is actuated by hitting the warm air, Move the adjusting plate 4 to open each opening 3a.
Slightly open. The warm air of the primary air C is
While flowing toward the side of the blow-out opening 2a, the air blows out from each opening 3a and flows down into the room from the edge of the blow-out opening 2a. The flow of warm air of the primary air C spreading downward from the outlet opening portion 2a toward the inside of the room attracts the air in the room and promotes mixing. By reducing the opening area of the opening 3a, the blowing speed of the warm air is increased, and the warm air of the primary air C, which is lighter than the room air, can reach the floor surface from the high ceiling 10 without fail. Can be warmed.

In the outlet device according to the present embodiment, the conditioned air blows out from each opening 3a while flowing toward the side of the blowing opening 2a along the substrate portion 3, and enters the room from the edge of the blowing opening 2a. Therefore, even when the ceiling 10 is low and the conditioned air easily reaches the floor immediately, the conditioned air can be reliably transmitted to a wide area in the room.

(Third Embodiment of the Present Invention) Hereinafter, an outlet device according to a third embodiment of the present invention will be described with reference to FIGS.
It will be described based on. FIG. 7 is a longitudinal sectional view of the outlet device according to the present embodiment, and FIG. 8 is a transverse sectional view of the outlet device according to the present embodiment.

As shown in FIGS. 7 and 8, the outlet device according to the present embodiment is divided into two parts at the center of the V-shape instead of the adjusting plate part 4 of the first embodiment. Two adjusting plate portions 4 each having a plate shape and slidable independently of each other are provided on the substrate portion 3, and two actuators 5 are provided over the respective adjusting plate portions 4 and the substrate portion 3. ,
One actuator 5 controls the opening area of the opening 3a on one side by moving the adjusting plate 4 according to the temperature in the same manner as in the first embodiment, and the other actuator 5 is specially adjusted for heating. The configuration is such that the opening 4a on the other side is controlled to be fully closed by moving the plate portion 4.

Next, the air blowing operation of the present embodiment based on the above configuration will be described. In the case of cooling, as in the first embodiment, when the cool air of the primary air E sent from the air-conditioning duct 11 enters the outlet chamber 2, the cooler hits the cool air, the actuator 5 operates, and the adjusting plate section is operated. 4 to make each opening 3a fully open. While the cool air of the primary air E flows toward the center of the blowout opening 2a along the substrate portion 3,
The air blows out from each opening 3a and flows down into the room from the center of the blowing opening 2a. As in the first embodiment, dew condensation does not occur in the blow-out opening 2a and the periphery thereof, and cooling can be efficiently performed in a short time.

In the case of heating, when warm air of the primary air E sent from the air-conditioning duct 11 enters the outlet chamber 2, the actuator 5 is acted upon by the warm air, and each adjusting plate portion 4 is moved. Each opening 3a on one side is slightly opened, and each opening 3a on the other side is fully closed. The warm air of the primary air E is blown out along the substrate portion 3 into the blowout opening 2a.
While flowing toward the center, it blows out from each opening 3a on one side and flows down into the room from the center of the blowing opening 2a. The flow of warm air of the primary air E going downward from the center of the blow-out opening 2a to the inside of the room is drawn as room air, and a drawn air flow is generated as the secondary air F. In particular, the room air near the ceiling 10 is drawn from the edge of the blow-out opening 2a to below the substrate section 3 in the blow-out chamber 2 with the warm air blowing out from the opening 3a. The secondary air F in the room that has been drawn into the outlet chamber 2 is
It touches the warm air of the primary air E immediately after leaving the opening 3a, and exits from the center of the blowing opening 2a while mixing. In addition to reducing the opening area of each opening 3a on one side and closing each opening 3a on the other side, the blowing speed of the warm air becomes remarkably large, so that the warm air which is lighter than the indoor air and hard to go down is reduced. In addition to being able to reach a farther floor with a strong airflow, the warm air attracts lower-temperature indoor air and exits through the outlet 2a while mixing with the air. The effect is enhanced, and the effect of raising the temperature of the indoor air is great, and the room can be warmed in a short time.

In the air outlet device according to the present embodiment, in the case of heating, each adjusting plate portion 4 is moved so that each opening 3a on one side is slightly opened and each opening on the other side is opened. By making the hole 3a fully closed, the blowing speed of the warm air can be doubled and the reach of the warm air can be doubled as compared with the case where the other side is opened in the same manner as one side, and the heating effect can be enhanced. And heating capacity can be improved without increasing the supply of warm air,
Energy savings and running costs can be reduced compared to the past.
