Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an air conditioner, and particularly to an air conditioner suitable for converging discharged air into a specific part in the entire width direction of a discharge port and increasing the wind speed. The present invention relates to an air conditioner having a wind direction device.

[Prior art] A conventional wind direction device for an air conditioner is, for example,
As described in Publication No. 94.4, a device is known that is equipped with a main wind direction switching plate located below the discharge and a sub-air direction switching plate placed on the second part of the outlet. These wind direction switching plates that change the direction of air flow are formed across the entire width direction of the discharge port, and the ventilation passages are also located across the entire width direction.

Furthermore, JP-A-60-1.69025 also describes a rotation control member made of a shape memory alloy as a means for driving a wind direction changing blade that changes the vertical air flow. It is also formed over the entire width direction with respect to the discharge port.

Furthermore, Japanese Patent Application Laid-Open No. 57-73331 states that when the heat source is turned on, conditioned air is blown upward (outside the residential area).
A technique is disclosed in which two outlets are provided so that conditioned air is blown out into the living area when the heat source is off. However, the wind direction plates at each outlet have the same inclination angle.

Furthermore, the technology described in Japanese Patent Publication No. 58-425.6,
Regarding air conditioners for automobiles, the central air outlet consists of a pair for the driver and an assistant, each of which can independently adjust the airflow direction down -L and left and right. , there is no description of any means for shielding the left and right sides and converging the blown air to the center.

[Problem to be Solved by the Invention] In the above conventional technology, a wind direction switching plate or a wind direction plate is provided across the entire width direction of the discharge port, and the wind direction switching plate is rotated to change the vertical air flow, for example. Since the airflow direction plate is tilted so that the flow of air flows in the same direction, the flow of air discharged is uniform over the entire width of the discharge port. Therefore, it is possible to partially block this discharge air flow and converge the wind direction to the central part, or to the left half.

Converge on the right half, according to the request of the resident,
Moreover, no consideration was given to making the discharged air reach a limited zone, and it was insufficient to reach areas where people were concentrated.

By the way, in recent years, with regard to air conditioners, inverter air conditioners with high heating power have become significantly popular, for example, for heating in winter. When the indoor temperature reaches the set room temperature and becomes stable, inverter air conditioners switch to low-output operation control and turn on as much as possible for economic reasons.

Care has been taken to ensure that it does not turn off. In such a situation, even if you reduce the so-called height difference between the temperature near the indoor floor and the temperature near the head of a person, the temperature near the floor where the person is exposed to cold radiation from the surroundings will still remain. It tends to be low.

Generally, it is preferable for the feet to be at a slightly higher temperature than the head. Therefore, there has been a growing demand for a way to concentrate warm air toward a living space and reach a portion of the indoor floor, for example.

The present invention has been made to solve the problems in the prior art described above, and an object of the present invention is to provide an air conditioner that can form a concentrated flow of air toward a living space.

[Means for Solving the Problems] In order to achieve the above object, the configuration of the first invention related to the air conditioner of the present invention is as follows. , an air conditioner comprising an inlet for sucking indoor air, and an outlet for blowing out conditioned air into the room, and the outlet is equipped with a wind direction switching means, wherein the air direction switching means is configured to change the wind direction at the outlet in a vertical direction. a plurality of vertical blades that are second wind direction plates that horizontally change the wind direction at the discharge port; A third wind direction plate forming a ventilation path is provided in the portion.

Furthermore, in order to achieve the above object, a second aspect of the air conditioner of the present invention has a structure including: an inlet for sucking indoor air into the indoor unit main body forming an air flow path including a heat exchanger and a blower; and a discharge port for blowing out the conditioned air into the room, and the discharge port is equipped with a wind direction switching means, the wind direction switching means comprising a plurality of longitudinal channels that horizontally change the wind direction at the discharge port. a main blade that is formed over the entire width of the discharge port and changes the wind direction at the discharge port in the vertical direction; a first auxiliary blade that integrally forms a twin blade with the main blade; and second auxiliary blades separately provided at both end portions, and the second auxiliary blades rotate the main blade and the first auxiliary blade only when the main blade and the first auxiliary blade rotate in a specific direction.
(8) It is configured to be located at a different angle from the rotation angle of the auxiliary blade.

Furthermore, in order to achieve the above object, the configuration of the third invention related to the air conditioner of the present invention is such that the indoor unit main body forming the air flow path including the heat exchanger and the blower has an inlet for sucking indoor air. , an air conditioner comprising a discharge port for blowing out conditioned air into a room, and a wind direction switching means at the discharge port, the wind direction switching means comprising: a horizontal blade that vertically changes the wind direction at the discharge port;
A plurality of vertical blades are provided to horizontally change the wind direction at the discharge port, and some of the plurality of vertical blades are used to block a portion of the entire width of the discharge port and form a ventilation path in other portions. They are arranged so that the inclination angle is maintained.

In summary, the above object is achieved by partially shielding a part of the ventilation path of the discharge port and freely converging the discharged air in any direction depending on the purpose.

[Effect] The functions of each of the above technical means are as follows.

In the first invention, in addition to the horizontal blades that change the discharged air in the vertical direction and the vertical blades that change the discharged air in the left-right direction, the ventilation path in the width direction of the discharge port is partially shielded over the entire width of the discharge port. A movable blade was formed at the most downstream part of the discharge port.

These horizontal blades and vertical blades each move independently,
Furthermore, the movable blades that partially shield the ventilation path can also be used to converge the discharged air in any direction, either for a limited time or continuously, as necessary.

Further, in the second invention, the wind direction plate provided over the entire width of the discharge port partially blocks the ventilation path in the width direction of the discharge port in addition to the main blade that changes the discharged air in the vertical direction. Second auxiliary vanes were formed at both ends.

When the second auxiliary blade reaches a position where the rotation angle of the main blade is inclined in one direction or more, the second auxiliary blade is positioned at an angle that prevents both ends of the discharge port in the width direction. As a result, the air to be discharged is not discharged from both ends of the discharge port, but is converged and discharged toward the central portion.

Furthermore, in the third invention, among the wind direction plates (vertical blades) that convert the air discharged from the discharge port into the horizontal direction, a certain part is positioned at an angle such that it faces straight to the center, and other wind direction plates overlap each other. It was arranged so that it was positioned at a similar angle.

As a result, some of the discharged air is blocked and is not discharged from these parts, but instead is converged and discharged into the ventilation path with less ventilation resistance of the wind direction plate (vertical blade) facing straight. It turns out.

Since the air conditioner of this embodiment is constructed as described above, its effects are compared with those of the prior art and are shown in FIGS. 8 to 11.

FIG. 8 is a side view of the hot air temperature distribution during heating operation of a conventional air conditioner with a low wind speed.

As can be seen from Figure 8, with the conventional type, even hot air at 30°C reaches only 0.5 to 0.55 m above the floor surface.

On the other hand, according to the air conditioner of this embodiment, as shown in FIG. But 0. 1~Q, reaching up to 1.5m. In other words, the floor is heated directly.

Also, when comparing the start-up time during heating, as shown in Figure 10, when looking at the start-up time from an outside temperature of 5°C to 21°C, the conventional one required approximately 69°C;
According to this embodiment, it starts up in about 3 minutes. In other words, the time is reduced to about half.

After standing up, depending on the user's preference, the
As shown in the figure, it is clear that warm air with reduced wind speed can be blown out from all openings of the two discharge ports 2 to switch to gentle normal heating.

It is clear that during cooling, the start-up can be made faster, and the horizontal blades 3 can be rotated in a substantially horizontal direction to gently blow out cold air.

Next, the aperture ratio of the ventilation passage will be explained.

Assuming that the length of the opening forming the ventilation passage 2a of the movable blade 5 shown in FIG.
The aperture ratio is given by Q/L. In the case of Figure 7, the opening length is Q1. + Q Corresponds to 2.

In Fig. 11, the horizontal axis represents the aperture ratio Q/, and the vertical axis represents the aperture ratio 5a above the floor.
The relationship is shown by taking the average temperature (°C) and noise (dB) at n.

As is clear from FIG. 11, the average temperature 5 cm above the floor increases as the opening ratio U/L decreases, but the noise also tends to increase exponentially. Therefore, for example, if the average temperature of the 5 mark on the floor is 21°C or more and the noise is 43dB or less, the aperture ratio may be in the range of 0.4 to 0°8, but for safety reasons, in this example, the aperture ratio is Rate Q, /L is 0.65 ~
It is desirable to set it to 0.75.

The horizontal blade 3 and the movable blade 5 can be rotated manually or by a motor such as a step motor, but the horizontal blade 3 and the movable blade 5 can be rotated by a horizontal blade motor 10 and a movable blade motor, respectively. An example will be described in which the motors are driven by a microcomputer.

An operation remote control 40 is attached to the air conditioner main body (indoor unit) shown in FIG. As shown in FIG. 12, the operation remote control 40 includes a wind direction operation button 4 for instructing the drive of the horizontal blade motor 10 and the movable blade motor 10.

Next, the operation will be explained using flowcharts 1 to 1 shown in FIG. 1.3.14.

First, the operation remote control 40 will be explained with reference to FIGS. 12.13.

In step 5-31, inputs to the wind direction operation buttons 41, 4↓ and the temperature switching button 42 are monitored. If there is an input, the type of button is determined (step S-32). When the operated button is the temperature switching button 42, a temperature signal is sent out (step S-33). On the other hand, if the type of button is the wind direction control button 41 or 41', a blade signal is sent out (step S-34).

19 In response to these signals, the horizontal blade 3 rotates in the {circle around (2)} direction and is positioned substantially downward, as shown in FIG. The movable blade 5 is also programmed to rotate in the V direction to match this position.

Next, 12th. ↓The operation of the air conditioner body will be explained with reference to Figure 4.

When the power supply 30 is on (step S-51), the control unit 5
9 and clearing the memory section 60 that stores the number of blade motor pulses and set temperature (step S-52).

Next, the horizontal blade 3 is driven by the horizontal blade motor 10, and the movable blade 5 is driven by the movable blade motor 10, and initialization is carried out to bring the horizontal blade 3 and the movable blade 5 to the initial position, for example, the position shown in FIG. (step 553). Next, the receiving circuit 5
5 is initialized (step S-54).

When these initializations are completed, the reception signal is monitored through the reception circuit 55 (step S-55), and if there is a signal,
The type of signal is determined (step S20-56), and if the signal is a blade selection signal, the position of the movable blade 5 is checked (step S-57).

When the movable blade 5 is in the W direction, the horizontal blade motor 10
Write the number of motor pulses in the storage unit 60 (step S
-58). Next, move the horizontal blade 3 to the position shown in FIG.
The horizontal blade 3 and the movable blade 5 are rotated at an angle of 30 to 35 degrees from the vertical direction so that they coincide at the leeward position of the horizontal blade 3 (step S-60).

Next, the rotation speeds of the indoor fan motor and compressor are calculated from the difference between the set temperature and the room temperature, and a rotation speed command is issued to the indoor fan motor 58 and compressor 57 (step 5-61.62).
,.

Note that, for example, the following control table is used to calculate the rotation speeds of the indoor fan motor 58 and the compressor 57.

When the movable blade 5 rotates in the direction ■ and is in the position shown in Figure 2 and receives the blade selection signal, it is not startup time, so the indoor fan motor 58 and compressor 57 return to normal operation. (Step S-63). Next, the movable blade 5 is rotated in the X direction (position in Figure 4) (step 5
-64. ), reads the pulses of the horizontal blade motor stored in the storage unit 60 before blade sorting (step S-65
), gives a command to the horizontal blade motor 10 (step S-
66).

On the other hand, if the type of signal is a temperature signal, the set temperature of the storage section 60 is also changed (step S-67), and normal operation is performed (step S-68).

As described above, when the operation remote control 40 is used, the horizontal blade 3 and the movable blade 5 rotate in a predetermined manner by simply pressing the wind direction operation button 41, 41, improving usability.

When the wind direction control button 41 is pressed, the peripheral part of the discharge port 2 is blocked by the movable blade 5, and most of the air volume is discharged from the central ventilation passage 2a. When 41 is pressed, the liquid will be discharged from the entire opening.

According to the embodiment of the first invention, the movable vanes 5 are positioned so as to shield both ends of the discharge port 2 in the width direction, so that the discharged air can be converged in the center, If the air volume is maintained at the same level, there is an effect that the air speed increases as the discharge area decreases.

Further, it is also possible to change the shielding position to the right half using the movable blade 11 and to the left half using the movable blade 12.

Furthermore, by sliding the shielding plate 14 formed with a plurality of guide frames 13, there is an effect that the position where the discharged air is to be converged can be arbitrarily selected without being limited.

Next, a second embodiment of the air conditioner according to the present invention will be described with reference to FIGS. 15 to 20.

In Figures 1.5.16, parts with the same symbols as in Figures 1 and 2 are the same parts as in the embodiment of the first invention, so
The explanation will be omitted.

In Figures 15.16 and 18.19, 23 is a main blade that changes the air flow (wind direction) at the discharge port 2 in the vertical direction, and 23a is integrally formed with the main blade 23 to form a twin blade. The first auxiliary blade 24 is a second auxiliary blade provided separately at both end portions of the first auxiliary blade 23a. That is, 24 the second auxiliary blade 24 is formed on the same surface as the first auxiliary blade 23a that is integral with the main blade 23, and only when the main blade 23 and the auxiliary blade 23a rotate in a specific direction, the main blade 24 is 23 and the auxiliary blade 23a.

25 is a projection serving as a stopper for suppressing the rotation of the second auxiliary blade 24, and 26 is a rotation axis of the main blade 23.

The operation of the main blade and the auxiliary blade will be explained with reference to FIG. 17.

As shown in FIG. 17(a), when the main blade 23 rotates in the X direction, the main blade 23 and the auxiliary blade 23a are positioned at the same angle. However, the auxiliary blades 24 at both ends are the protrusions 2
5, it remains stationary and the ventilation path is blocked.

When the main blade 23 rotates in the Y direction, it enters the state shown in FIG. 17(b) and blocks the discharge port over its entire width. When performing normal ventilation, cooling, heating, etc., it is sufficient to sequentially rotate them so as to obtain the states shown in FIGS. 1-7(c) and (d), respectively. It can also be reproduced in the same way even if it is returned to its original state.

The auxiliary blade 24 is the main blade 23 in FIG. 17(a).
Only when rotated in the X direction, the angle becomes different as shown in FIGS. 16 and 19, and other than that, the main blade 23 and the auxiliary blade 23a maintain the same plane on one rotation axis 26. There is.

In Figures 18 and 19, 27 is a spring set between the main blade 23 and the auxiliary blade 24, and this spring 27
When the main blade is rotated in a specific direction (see FIG. 17(a)) (see FIGS. 17(b) to (d)),
That is, when no external force is applied, it functions as an elastic means for holding the auxiliary blade 24 on the same plane as the auxiliary blade 23a.

Next, another embodiment according to the second invention will be described with reference to FIG. 20. In the figure, parts with the same reference numerals as those in FIG. 16 are equivalent parts, so their explanation will be omitted.

In FIG. 20, 28 is a main blade that changes the air flow in the vertical direction, 28a is a first auxiliary blade that integrally forms a twin blade with the main blade 28, and 29 is a first auxiliary blade 28a. This is a second auxiliary blade provided separately at both end portions of the blade.

In the embodiment shown in FIG. 20, a movable blade 28b is attached to one end of the main blade 28 in the front width direction of the discharge port 2, and only when the main blade 28 is rotated in the Z direction, the main blade 28 and the movable blade 28b form different angles. When the main blade 28 is returned in the opposite direction, the main blade 28 and the movable blade 28b are always in the same plane.

In this way, according to the second embodiment of the invention, the main blade 23
Since the auxiliary vanes 24 shield both ends of the discharge port 2 in the width direction only when the discharge port 2 rotates in the X direction shown in FIG. 17(a), it is possible to converge the discharged air to the center. When the air volume is the same, there is an effect of increasing the wind speed.

Furthermore, when the auxiliary blade 24 is made resilient by the spring 27 and no external force is applied, the other auxiliary blade 23a can always be held in the same plane.

Furthermore, by mounting the movable blade 28b on a part of the main blade 28, there is no gap between the dew pan 7 and the movable blade 28b when the discharged air is converged to the center.
The convergence effect on the ventilation path to be formed will be large.

Next, a third embodiment of the air conditioner according to the present invention will be described with reference to FIGS. 21 to 25.

2 is an enlarged plan cross-sectional view of the discharge port in FIG. 1. FIG.

In FIGS. 21 and 22, parts with the same symbols as those in FIGS. 1 and 2 are the same parts as in the previous embodiment, so a description thereof will be omitted.

In Figures 21 and 22, 33 is a horizontal blade that changes the air flow at the discharge port 2 in the vertical direction;
35 and 36 are vertical blades that change the flow of air in the horizontal direction, and these blades constitute a wind direction switching means.

28- As shown in FIG. 23, among the vertical blades 34, 35, and 36, the vertical blade 34 is positioned straight toward the center, and the vertical blade 35 is positioned at an angle that shields the left side portion of the discharge port 2. Feather 3
6 is positioned at an angle that shields the right side of the discharge 1'' 2, the vertical blades 35 and 36 operate independently, and their front end portions are inclined toward the center.

Further, in the example shown in FIG. 24, the vertical blade 34 is oriented straight toward the center, and the left side portion is shielded by the vertical blade 37a and the right side portion is shielded by the vertical blade 37b.
It is possible to move and operate a and 37b.

Furthermore, in the example shown in FIG. 25, the ventilation passage 2a of the discharge port 2
The vertical blades 38 and 39 are movable, so that the vertical blades 38 and 39 can be moved to the left side or to the right side.

3, according to the third embodiment of the invention, the inclination angle of the plurality of vertical blades is changed to divide the ventilation passage 2a into a portion forming the ventilation passage 2a and a shielding portion. The vertical blades act as ventilation resistance for the discharged air, blocking the flow, and converging the direction of the air so that it is discharged from the ventilation passage 2a.If the air volume is maintained at the same level, the ventilation A large effect is that the wind speed increases as the cross-sectional area of the passage 2a decreases.

Also, since the shielding vertical blades were made to move,
It is possible to have a cheaper structure.
