[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner having an indoor unit equipped with a blower fan that blows inhaled air.

[0002]

2. Description of the Related Art FIG. 20 is a schematic side sectional view showing an indoor unit of a conventional air conditioner. The indoor unit 1 of the air conditioner
The main body is held by the cabinet 2, and a front panel 3 having suction ports 4a and 4c on the upper surface side and the front surface side is detachably attached to the cabinet 2. The cabinet 2 is provided with a claw portion (not shown) on the rear side surface, and is supported by fitting the claw portion to a mounting plate attached to a wall in the room.

In the gap between the lower end of the front panel 3 and the lower end of the cabinet 2, there is formed a substantially rectangular air outlet 5 extending in the width direction of the indoor unit 1. Inside the indoor unit 1, a ventilation path 6 is formed that communicates with the air outlet 5 from the suction ports 4a and 4c. A blower fan 7 that sends out air is arranged in the blower path 6. As the blower fan 7, for example, a cross flow fan or the like can be used.

An air filter 8 for collecting and removing dust contained in the air sucked from the suction ports 4a, 4c is provided at a position facing the front panel 3. Between the blower fan 7 and the air filter 8 in the blower path 6,
The indoor heat exchanger 9 is arranged.

The indoor heat exchanger 9 is connected to a compressor (not shown), and the refrigeration cycle is operated by driving the compressor. Due to the operation of the refrigeration cycle, the indoor heat exchanger 9 is cooled to a temperature lower than the ambient temperature during cooling. Further, during heating, the indoor heat exchanger 9 is heated to a temperature higher than the ambient temperature.

Drain pans 10 for collecting dew condensation that has fallen from the indoor heat exchanger 9 at the time of cooling or dehumidifying are provided in front and rear lower portions of the indoor heat exchanger 9. In the vicinity of the blower outlet 5 in the blower path 6, horizontal louvers 11a and 11b that face the outside and can change the vertical blowout angle from substantially horizontal to downward are provided. A vertical louver 12 is provided behind the horizontal louvers 11a and 11b so that the blowing angle in the left-right direction can be changed.

In the air conditioner having the above structure, when the operation of the air conditioner is started, the blower fan 7 is rotationally driven,
Refrigerant from an outdoor unit (not shown) flows into the indoor heat exchanger 9 to operate the refrigeration cycle. As a result, air is sucked into the indoor unit 1 through the suction ports 4a and 4c, and the dust contained in the air is removed by the air filter 8.

The air taken into the indoor unit 1 exchanges heat with the indoor heat exchanger 9 and is cooled or heated. The vertical louvers 12 and the horizontal louvers 11a, 1
The direction is regulated in the left-right direction and the vertical direction by 1b, and the air is discharged downward from the outlet 5 into the room.

Immediately after the start of the operation of the air conditioner, it is necessary to quickly circulate the indoor air. For this reason, the rotation speed of the blower fan 7 is increased, and the air that has undergone heat exchange in the indoor heat exchanger 9 is vigorously discharged from the outlet 5. Figure 2
1 shows the behavior of the air flow in the room at this time. Outlet 5
The air (B) sent downward from (see FIG. 20) flows through the room R as indicated by the arrow and returns to the suction ports 4a and 4c.

When the temperature difference between the room temperature and the set temperature becomes small, the blower fan 7 is adjusted to gradually reduce the blown air amount to make a slight wind, and the horizontal louvers 11a and 11b set the wind direction in a substantially horizontal direction. FIG. 22 shows the behavior of the air flow in the room at this time. The air (B ′) sent out from the air outlet 5 (see FIG. 20) in a substantially horizontal direction flows through the room R as indicated by the arrow and returns to the suction ports 4a and 4c.

An air conditioner equipped with an ion generator for generating ions in the indoor unit 1 is also known. In this air conditioner, the air cleaning effect and the relaxation effect by sterilization and the like can be obtained by sending out the ions together with the conditioned air from the air outlet 5.

[0012]

According to the above-mentioned conventional air conditioner, the air conditioner is usually arranged at a position higher than the height of the user and is blown from the air outlet 5 in a substantially horizontal direction or a downward direction. It FIG. 23 shows the temperature distribution inside the room in a so-called cooling stable state where the room R shown in FIGS. 21 and 22 has reached the set temperature (28 ° C.) when the room R is cooled.

The size of the room R is 6 tatami (height 2400 m
m, width 3600 mm, depth 2400 mm). The measurement points are 6 in the height direction and in the lateral direction at 600 mm intervals in the central cross section of the room R indicated by the one-dot chain line D in FIG.
A total of 48 points, 8 points, are measured. Further, the air flow in the cooling stable state has a slight air volume and a substantially horizontal air flow direction.

According to the figure, the cold air blown out from the indoor unit 1 descends because of its large specific gravity. As a result, a wind having a temperature of about 5 ° C. lower than the set temperature of 28 ° C. pours into the center of the room R. For this reason, if the ventilation is continued in the state where the temperature has reached around the set temperature, the user is constantly hit with cold wind or warm wind. Therefore, there is a problem that the user feels uncomfortable and the body temperature of the user is locally lowered during the dehumidifying operation or the cooling operation, which is harmful to health. There is also a problem that the temperature variation in the room R becomes large.

FIG. 24 shows the ion concentration distribution in the room in the stable cooling state when the ions are sent out together with the conditioned air. The size of the room R is the same as in FIGS. 21 to 23, and the same cross section as that in FIG. 23 is measured. The set temperature is 28 ° C., the air volume is light, and the wind direction is substantially horizontal. The arrows in the figure show the state of the airflow at this time.

Further, positive ions H ⁺ (H ₂ O) _n and negative ions O ₂ by the ion generating device ^- it has been sent from the air outlet 5 to generate the (H ₂ O) _n, numerical values in FIG. Ion concentration (unit: pcs / cc) and +/- signs indicate positive and negative ions, respectively.

According to the figure, since the momentum of the air flow blown out from the indoor unit 1 is weak, the ions cannot reach the end of the room R, and the vicinity of the wall surface facing the indoor unit 1 and the region directly below the indoor unit 1 Ion concentration is low. That is, there is a problem that the ion concentration at the end of the room becomes lower than that at other places, and a sufficient bactericidal effect or relaxation effect cannot be obtained.

In order to solve these problems, for example, as disclosed in Japanese Patent Application No. 2001-296902, an air conditioner capable of sending conditioned air upward from a blowout port has been researched and developed. FIG. 25 is a schematic side sectional view showing an indoor unit of this air conditioner, and the same portions as those in FIG. 20 described above are denoted by the same reference numerals.

The air outlet 5 of the indoor unit 1 has a first opening 5a and a second opening 5b. The first opening 5a is arranged at the end of the air passage 6 so as to face downward. Second opening 5
b is a branch passage 1 that branches upward from the air flow path 6 with an inclination.
3 communicates with the ventilation path 6.

At both ends of the branch passage 13, a rotary shaft 14a,
Rotating plates 14, 1 pivotally supported on the front panel 3 by 15a.
5 are provided. Further, the front surface of the front panel 3 is shielded so that the suction port 4c (see FIG. 20) is not formed, and an air guide portion 20 protruding forward is provided at the upper portion of the front panel 3.

When the operation of the air conditioner is started, the suction port 4
The air taken into the indoor unit 1 from a is the indoor heat exchanger 9
Heat exchange with and is cooled or heated. The vertical louver 12 and the horizontal louvers 11a and 11b pass through the air passage 6 to regulate the direction in the left and right and up and down directions, and the air outlet 5 extends from the first opening 5a to a substantially horizontal direction or a downward direction as shown by an arrow A1. To be sent indoors.

Immediately after the start of the operation of the air conditioner, the rotation speed of the blower fan 7 is increased and the air having undergone heat exchange in the indoor heat exchanger 9 is vigorously discharged from the air outlet 5. When the temperature sensor (not shown) detects that the temperature difference between the room temperature and the set temperature is small, the blower fan 7 is adjusted to gradually reduce the blown air amount.

Then, as shown in FIG. 26, the horizontal louver 1
1a and 11b rotate and the 1st opening part 5a is closed.
At the same time, the rotating plates 14 and 15 rotate to open the second opening 5b and the branch portion of the branch passage 13. This allows
The conditioned air flowing through the air blowing path 6 flows through the branch passage 13 and is discharged from the second opening 5b, and is guided upward as shown by an arrow A2. Then, the conditioned air rising along the front surface of the front panel 3 is sucked into the suction port 4a by the air guide portion 20.
Will be guided forward below.

Therefore, the user is not constantly exposed to cold wind or warm wind, the discomfort of the user can be prevented and the comfort can be improved, and the body temperature of the user is locally reduced during cooling. It is possible to improve health safety without doing so. Further, since the front surface of the front panel 3 is shielded and air is guided forward by the air guide portion 20 below the suction port 4a, so-called short circuit in which conditioned air flows into the indoor unit 1 can be prevented. .

However, according to the above air conditioner, the conditioned air sent upward from the second opening 5b is
The fluid flows along the surface of the front panel 3 of the indoor unit 1 due to the Coanda effect in which the fluid tends to flow along the wall surface.
For this reason, the viscosity of the air reduces the wind speed, and the reaching distance of the airflow guided forward is significantly reduced. Therefore, the air flow does not reach every corner of the room, and the problem that the temperature distribution and the ion concentration distribution are non-uniform cannot be solved yet.

The air taken in from the suction port 4a passes through the space and comes into contact with the indoor heat exchanger 9 in a large area.

The indoor heat exchanger 9 is a compressor 62 (see FIG. 2).
The refrigeration cycle is operated by driving the compressor. Due to the operation of the refrigeration cycle, the indoor heat exchanger 9 is cooled to a temperature lower than the ambient temperature during cooling. During heating, the indoor heat exchanger 9 is heated to a temperature higher than the ambient temperature. A temperature sensor 61 for detecting the temperature of the sucked air is provided between the indoor heat exchanger 9 and the air filter 8.
(See FIG. 2) is provided, and a control unit 60 (see FIG. 2) that controls the drive of the air conditioner is provided on the side of the indoor unit 1.

Drain pans 10 for collecting dew condensation that has fallen from the indoor heat exchanger 9 during cooling or dehumidification are provided at the front and rear lower portions of the indoor heat exchanger 9. Front drain pan 1
Reference numeral 0 is attached to the front panel 3, and the rear drain pan 10 is formed integrally with the cabinet 2.

An ion generator 30 is installed in the front drain pan 10 with the discharge surface 30a facing the air blowing path 6. Ions generated from the discharge surface 30a of the ion generator 30 are discharged into the air passage 6 and blown out from the air outlet 5 into the room. The ion generator 30 has a discharge electrode, and when the applied voltage is a positive voltage due to corona discharge, it is mainly H
⁺ (H ₂ O) to generate positive ions consisting of _n, in the case of negative voltage mainly O ₂ ^- (H ₂ O) to generate negative ions consisting of _m.

The first opening 5a of the air outlet 5 in the air passage 6
In the vicinity of, horizontal louvers 11a and 11b are provided, which face the outside and can change the vertical blowing angle from substantially horizontal to downward. A vertical louver 12 is provided on the inner side of the horizontal louvers 11a and 11b, the vertical louver 12 being capable of changing the blowing angle in the left-right direction.

The second opening 5b communicates with the air blowing path 6 through a branch passage 13 which is inclined upward from the air blowing path 6 and branches.

Rotating plates 14 and 15 pivotally supported by the front panel 3 by rotating shafts 14 a and 15 a are provided at both ends of the branch passage 13.

When the branch passage 13 is closed by the rotating plate 15, the rotating plate 15 forms the inner wall surface of the air blowing path 6 and guides the air flow. As a result, an increase in the flow resistance of the air flowing through the blower path 6 is prevented. In addition, the air guide surface 20a on the lower surface of the air guide portion 20 is the upper wall surface 1 of the branch passage 13.
It is formed on substantially the same plane as 3a and suppresses an increase in air resistance.

FIG. 2 is a block diagram showing the structure of the air conditioner. The control unit 60 is composed of a microcomputer,
Based on the operation by the user and the input of the temperature sensor 61,
Blower fan 7, compressor 62, ion generator 30, vertical louver 12, horizontal louvers 11a, 11b and rotating plates 14, 1
5 drive control is performed.

In the air conditioner having the above structure, when the operation of the air conditioner is started, the blower fan 7 is rotationally driven,
Refrigerant from an outdoor unit (not shown) flows into the indoor heat exchanger 9 to operate the refrigeration cycle. As a result, air is sucked into the indoor unit 1 through the suction port 4a, and the dust contained in the air is removed by the air filter 8.

The air taken into the indoor unit 1 exchanges heat with the indoor heat exchanger 9 and is cooled or heated. The vertical louvers 12 and the horizontal louvers 11a, 1
The direction is regulated in the left-right direction and the up-down direction by 1b, and the air is discharged from the air outlet 5 toward the interior in a substantially horizontal direction or a downward direction as shown by an arrow A1.

Immediately after the start of the operation of the air conditioner, it is necessary to quickly circulate the indoor air. Therefore, the air volume is set to, for example, “strong”, the rotation speed of the blower fan 7 is increased, and the air that has undergone heat exchange in the indoor heat exchanger 9 is vigorously discharged from the outlet 5. FIG. 3 shows the behavior of the air flow in the entire room at this time. First opening 5a (see FIG. 1)
The air (B) discharged downward from the air flows through the room R as shown by the arrow and returns to the suction port 4a.

When the temperature difference between the room temperature and the set temperature becomes small, the blower fan 7 is adjusted to gradually reduce the blown air amount to set the air amount to, for example, "light wind". Then, as shown in FIG. 4, the horizontal louvers 11a and 11b rotate to rotate the first opening 5
a is set to a slightly opened state, and the rotating plates 14 and 15 are
Is rotated to open the second opening 5b and the branch portion of the branch passage 13.

As a result, the air taken in from the suction port 4a flows through the blower path 6 and the branch passage 13 and is blown upward through the gap between the second opening 5b and the lateral louvers 11a, 11b, and is blown by the air guide portion 20. It is guided forward and upward as shown by an arrow A2. FIG. 5 shows the behavior of the air flow in the room at this time. First and second openings 5a, 5b (see FIG. 4)
The air (B ″) sent from the upper part to the front side flows through the room R as shown by the arrow and returns to the suction port 4a.

Therefore, the user is not constantly exposed to cold wind or warm wind, and the user's discomfort can be prevented and comfort can be improved. Furthermore, the health safety can be improved without locally lowering the body temperature of the user during cooling.

By opening the first opening 5a slightly by the lateral louvers 11a and 11b, the first opening 5a is opened.
The air blown out of is guided upward by the Coanda effect along the horizontal louvers 11a and 11b. At this time, since the conditioned air passes through both sides of the lateral louvers 11a and 11b, there is no temperature difference between the two sides, and dew condensation can be prevented.
When the horizontal louvers 11a and 11b are subjected to heat insulation treatment, the first opening 5a may be closed.

Further, since the lateral louver rotates, it is formed so as to avoid interference with the wall surface of the blower path 6 due to the rotation. For this reason, when the lateral louver is composed of one plate-shaped member, the gap becomes large when the first opening 5a is closed, and the air leaking from the gap directly hits the user. Therefore, it is more desirable to form the lateral louvers 11a and 11b by a plurality of plate-like members as in the present embodiment because the gap when closed can be reduced.

Furthermore, by arranging the plurality of horizontal louvers 11a and 11b at different angles, the conditioned air is easily guided upward along the respective horizontal louvers 11a and 11b, leaks from the gap and is blown downward. Air can be reduced. The color, shape, etc. of the rotating plate 14 are set to the horizontal louvers 11a, 1
It is more desirable to form the rotating plate 14 like a part of the horizontal louver so as to have an appearance similar to that of the horizontal louver 1b because the appearance is improved.

The conditioned air blown out from the second opening 5b is blown upward and forward by the air guide 20 as a jet flow not along the front panel 3. Therefore, it is possible to prevent a short circuit in which the conditioned air flows into the indoor unit 1 from the suction port 4a.

As a result, it is possible to prevent the cooling efficiency or the heating efficiency of the air conditioner from deteriorating, increase the dew condensation on the surface of the front panel 3 and freeze the dew condensation water adhering to the surface of the indoor heat exchanger 9. Can prevent growth. Therefore, it is possible to prevent the dew condensation water or the frozen ice melted water from being released into the room, and to prevent the cabinet 2 and the front panel 3 from being deformed or damaged due to the pressing force of the grown ice.

Further, it is possible to prevent a decrease in wind speed caused by the contact with the front panel 3 due to the viscosity of the air. For this reason, the airflow reaches every corner of the room, and the stirring efficiency in the room can be improved.

FIG. 6 shows the temperature distribution in the room in the so-called cooling stable state where the room R shown in FIGS. 3 and 5 has reached the set temperature (28 ° C.) when the room R is cooled. The size of the room R is 6 tatami (height 2400 mm, width 3600 mm, depth 2400) as in the conventional example shown in FIGS.
5), and the measurement points are a total of 48 points of 6 points in the height direction and 6 points in the lateral direction at the center cross section of the room R shown by the one-dot chain line D in FIG.
Further, the air flow in the cooling stable state has a slight air volume and an upward air direction.

As is clear from FIGS. 5 and 6, the conditioned air blown forward and upward from the first and second openings 5a and 5b of the indoor unit 1 is guided to the air guide portion 20 and the room R is cooled. Reach the ceiling. Then, by the Coanda effect, the air is sucked into the suction port 4a from both sides of the indoor unit 1 along the wall surface facing the indoor unit 1, the floor surface, and the wall surface on the indoor unit 1 side from the ceiling surface in order.

As a result, the air flow greatly agitates the entire room, and the temperature distribution in the room R becomes uniform near the set temperature.
That is, except for a part above the room R, the entire living area of the user is substantially equal to the set temperature of 28 ° C., a temperature variation is small, and a comfortable space in which the direct wind hardly hits the user can be obtained. .

Further, FIG. 7 shows an ion concentration distribution in a stable cooling state by driving the ion generator 30 in the same room R as described above to send out ions together with conditioned air.
The same cross section D (see FIG. 5) as in FIG. 6 was measured, and the set temperature was 2
The temperature is 8 ° C, the air volume is light, and the wind direction is upward. The arrows in the figure show the behavior of the airflow at this time. Numerical values in the figure indicate the ion concentration (unit: pcs / cc), and +/− signs respectively represent positive and negative ions.

According to the figure, as described above, the ions together with the conditioned air are transferred from the ceiling surface to the indoor unit 1 by the Coanda effect.
The wall surface facing the floor, the floor surface, and the wall surface on the indoor unit 1 side,
The air is sucked into the suction port 4a from both sides of the indoor unit 1. Therefore, since the airflow reaches the end of the room R quickly, the ion concentration at the end of the room R can be increased more than ever before. In general, air tends to stagnate at the end of the room, and the air purification capacity is reduced in the conventional technique. However, the air purification capacity at the room edge can be greatly enhanced by the above effect.

When the ion generator 30 generates more negative ions than positive ions and emits them into the room, a relaxation effect due to the negative ions can be obtained. Even in this case, a uniform ion concentration can be obtained as in the above case.

The airflow blown upward and forward from the second opening 5b of the air outlet 5 of the indoor unit 1 and the first opening 5 of the air outlet 5.
Ions may be diffused throughout the room by alternately using the airflow blown forward and downward from a. This way,
It is possible to increase the ion concentration at the end of the room and also to deliver the ions to the approximate center of the room. This allows
It is possible to increase the ion concentration in the entire room and make the ion concentration in the room more uniform.

The drain pan 1 on the upper surface of the air guide portion 20 and on the front side.
The upper surface of 0 contacts the air before passing through the indoor heat exchanger 9, and the lower surface of the air guide part 20 and the lower surface of the drain pan 10 in front contact the conditioned air sent out from the air outlet 5. Therefore, the air guide portion 20 and the front drain pan 10 tend to cause dew condensation due to the temperature difference between the two surfaces. However, if a heat insulating material such as foaming resin is fixed to the air guide portion 20 and the front drain pan 10, dew condensation can be prevented. So more desirable. Wind guide 2
The 0 and front drain pans 10 may be formed hollow to provide a heat insulating material including an air layer and a vacuum layer.

Similarly, when the dehumidifying operation is performed by the air conditioner, the same effect as described above is obtained when the low temperature air dehumidified by the heat exchange with the indoor heat exchanger 9 is blown upward by a breeze. be able to. For the dehumidifying operation, a reheat dry type dehumidifying device having an evaporator and a condenser in the indoor heat exchanger may be used.

That is, the air that has been cooled and dehumidified by heat exchange in the evaporating section is heated in the condensing section by heat exchange and sent out into the room, so that dehumidification can be performed without lowering the room temperature. At this time, even if the temperature is raised in the condenser, it is possible to prevent the air that is still lower than the body temperature from hitting the user all the time, and to make the temperature distribution in the room uniform.

Next, FIG. 8 is a schematic side sectional view showing the indoor unit 1 of the air conditioner of the second embodiment. The same parts as those in the first embodiment shown in FIGS. 1 and 4 described above are designated by the same reference numerals. The difference from the first embodiment is that the rotating plate 15 (see FIG.
This is a point that the rotating plate 14 is subjected to a heat insulating treatment for preventing dew condensation. Other parts are the same as those in the first embodiment.

Similarly to the above, when the operation of the air conditioner is started, the indoor air is sucked into the indoor unit 1 through the suction port 4a. The air taken into the indoor unit 1 exchanges heat with the indoor heat exchanger 9 and is cooled or heated. And the air flow path 6
The vertical louvers 12 and the horizontal louvers 11a and 11b pass through the pipes and regulate the direction thereof in the left-right and up-down directions, and the air is discharged from the air outlet 5 toward the substantially horizontal direction or the downward direction as shown by an arrow A1. At this time, a vortex 25 is generated in the branch passage 13 part. The vortex 25 functions as a wall surface of the air flow path 6, and the conditioned air is discharged from the first opening 5 a along the vortex 25.
Highly efficient ventilation is possible without a large increase in pressure loss.

When the temperature sensor 61 (see FIG. 2) detects that the temperature difference between the room temperature and the set temperature has become small,
By adjusting the blower fan 7, the amount of blown air is gradually reduced. Then, as shown in FIG. 9, the horizontal louvers 11a and 11b are rotated to set the first opening 5a to a slightly opened state, and the rotating plate 14 is rotated to open the second opening 5b. To be done.

As a result, the conditioned air flowing through the air blowing path 6 flows through the branch passage 13 and is discharged from the gap between the second opening 5b and the lateral louvers 11a and 11b, and the air guiding portion 20 causes the air to flow as indicated by arrow A2. A jet stream is formed without going along the front panel 3 and is blown upward and upward. Therefore, the same effect as that of the first embodiment can be realized with a simpler structure and almost without degrading the blowing efficiency or the like.

Next, FIG. 10 is a schematic side sectional view showing the indoor unit 1 of the air conditioner of the third embodiment. Figure 1 above,
The same parts as those in the first embodiment shown in FIG. 4 are designated by the same reference numerals.

Further, a suction port 4c formed in a slit shape is provided on the front surface side of the front panel 3. Other parts are the same as those in the first embodiment.

Similarly to the above, when the operation of the air conditioner is started, the indoor air is sucked into the indoor unit 1 through the suction ports 4a and 4c. The air taken into the indoor unit 1 exchanges heat with the indoor heat exchanger 9 and is cooled or heated. Then, the vertical louver 12 and the rotating plates 15 and 26 regulate the direction in the left-right and up-down directions through the blower path 6 and enter the room from the outlet 5 toward the substantially horizontal direction or the downward direction as shown by an arrow A1. Sent out.

When the temperature sensor 61 (see FIG. 2) detects that the temperature difference between the room temperature and the set temperature has become small,
By adjusting the blower fan 7, the amount of blown air is gradually reduced. Then, as shown in FIG. 11, the rotating plate 26 rotates to move the first plate.
The opening 5a is shielded but the second opening 5b is set to an open position, and the rotating plate 15 rotates to open the branch portion of the branch passage 13. As a result, the conditioned air flowing through the blower path 6 flows through the branch passage 13 and the second opening 5b.
The air is blown out by the air guide portion 20 toward the upper front side as a jet flow not along the front panel 3 as shown by an arrow A2.

Therefore, when the conditioned air is sent downward, the delicate control of the wind direction is slightly more difficult than in the first and second embodiments, but the same effect as in the first and second embodiments is further simplified. Can be realized with a simple structure. Further, since the suction port 4c is provided above the blowout port 5, a short circuit occurs as shown by an arrow A3 when the conditioned air is sent upward. However, since the short circuit is suppressed to the minimum by the air guide portion 20, the cooling efficiency can be comprehensively improved by increasing the intake air amount. The suction port 4c may be provided on the front surface side of the front panel 3 of the first and second embodiments.
