Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner that takes in ambient air and sends out conditioned air.

[0002]

2. Description of the Related Art FIG. 11 is a schematic side sectional view showing an indoor unit of a conventional air conditioner. A main body of an indoor unit 1 of an air conditioner is held by a 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 during cooling or dehumidification are provided at the 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 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.

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. Then, when the temperature difference between the room temperature and the set temperature becomes small, the amount of air blown gradually decreases due to the adjustment of the blower fan 7. As a result, the interior of the chamber is finely formed with a uniform temperature distribution.

[0009]

However, according to the above-mentioned conventional air conditioner, the air conditioner is usually installed at a position higher than the height of the user, and extends substantially horizontally or downward from the outlet 5. Blown. For this reason, if the ventilation is continued in the state where the temperature has reached the vicinity of the set temperature, the user is constantly hit with cold wind or warm wind. Therefore, there is a problem that the user feels uncomfortable. In addition, there is a problem that the body temperature of the user is locally lowered during the dehumidifying operation or the cooling operation, which is harmful to health.

In order to solve these problems, researches and developments have been made on air conditioners which can send conditioned air upward from the air outlet. FIG. 12 is a schematic side sectional view showing an indoor unit of this air conditioner, and the same parts as those in FIG. 11 are designated 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. The second opening 5b communicates with the air blowing path 6 through a branch passage 13 that is inclined and branched upward from the air blowing path 6. 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 operation of the air conditioner is started, the suction port 4

The direction is regulated in the left-right and up-down directions by 1b, and the air is discharged from the air outlet 5 into the room from the first opening 5a 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. 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. 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. 13, 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
Conditioned air flowing through the blower 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.

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, it is possible to improve health safety without locally lowering the body temperature of the user during cooling.

However, according to the above air conditioner, the conditioned air sent upward from the second opening 5b is
As shown by an arrow A3, the air is taken into the indoor unit 1 through the suction port 4c provided on the front panel 3, and a so-called short circuit is generated. Therefore, there is a problem that cooling efficiency or heating efficiency of the air conditioner is reduced.

Further, during the cooling operation or the dehumidifying operation, the cool air sent out from the second opening 5b passes through the indoor heat exchanger 9, so that the refrigerant in the indoor heat exchanger 9 can absorb sufficient heat. Can not. For this reason, the temperature of the indoor heat exchanger 9 decreases as compared with the normal time, and dew condensation increases and dew condensation water freezes.

When the cooling operation or the dehumidifying operation is continued, ice grows on the surface of the indoor heat exchanger 9, and the ice at a position away from the indoor heat exchanger 9 is not maintained at a low temperature and a part thereof is thawed. When the melted water droplets are dropped on the blower fan 7, the second opening 5b is formed.
Is released indoors. Further, the temperature of the indoor heat exchanger 9 is lowered, and the surfaces of the cabinet 2 and the front panel 3 are dewed, so that the dew condensation water drops. Due to these, there is a problem that the room is flooded. There is also a problem that the cabinet 2 and the front panel 3 are damaged or deformed by the pressing force of the ice that has grown on the surface of the indoor heat exchanger 9.

An object of the present invention is to provide an air conditioner capable of improving comfort and health safety and also improving cooling efficiency or heating efficiency. It is another object of the present invention to provide an air conditioner capable of preventing a short circuit and preventing water in the room due to dew condensation and damage or deformation of the air conditioner.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. For convenience of description, the same parts as those in FIGS. 12 and 13 of the conventional example are designated by the same reference numerals.
FIG. 1 is a schematic side sectional view showing an indoor unit of an air conditioner of a first embodiment. The main body of the indoor unit 1 of the air conditioner is held by the cabinet 2.

Inside the indoor unit 1, there is formed an air blowing path 6 which communicates from the suction ports 4a and 4c to the air outlet 5. In front of the cabinet 2 in the blower path 6, a blower fan 7 that sends out air is arranged. 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. A space having a predetermined interval is provided between the front panel 3 and the indoor heat exchanger 9, and the air taken in through the suction ports 4a and 4c comes into contact with the indoor heat exchanger 9 in a large area through the space. It is supposed to do.

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. During heating, the indoor heat exchanger 9 is heated to a temperature higher than the ambient temperature. A temperature sensor (not shown) for detecting the temperature of the sucked air is provided between the indoor heat exchanger 9 and the air filter 8.
Is provided.

Drain pans 10 for collecting the dew condensation that has fallen from the indoor heat exchanger 9 during cooling or dehumidification are provided at the lower front and rear of the indoor heat exchanger 9. Front drain pan 1
0 is attached to the front panel 3, and the rear drain pan 10 is formed integrally with the cabinet 2. In the vicinity of the first opening 5a of the air outlet 5 in the blower path 6, horizontal louvers 11a and 11b that face the outside and can change the vertical blowing angle from substantially horizontal to downward are provided. 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 passage 6 through a branch passage 13 that is inclined upward from the air blowing passage 6 and branches. Rotating shafts 14a and 15a are provided at both ends of the branch passage 13.
Rotating plates 14 and 15 pivotally supported by the front panel 3 are provided. When the branch passage 13 is closed by the rotating plate 15, the rotating plate 15 forms the inner wall surface of the blower 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 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. Further, the opening / closing plate 19 rotates to open the suction port 4c. 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 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. 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. When the temperature sensor detects that the temperature difference between the room temperature and the set temperature is small, the blower fan 7 controls to gradually reduce the blown air amount.

Then, as shown in FIG.
a and 11b rotate to close the first opening 5a, and the rotating plates 14 and 15 rotate to rotate the second opening 5b and the branch passage 1.
The branch part of 3 is opened. Further, the opening / closing plate 19 rotates to close the suction port 4c. As a result, the air taken in from the suction port 4a flows through the air blowing path 6 and the branch passage 13 and is sent out from the second opening 5b, and is guided upward as shown by an arrow A2. 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.

Further, the adjustment air sent upward from the second opening 5b passes through the front surface of the front panel 3, but the front side of the front panel 3 is shielded by the opening / closing plate 19, so that a short circuit may occur. Absent. Therefore, it is possible to prevent the cooling efficiency or the heating efficiency of the air conditioner from decreasing. Further, since a short circuit does not occur, it is possible to prevent dew condensation on the surface of the front panel 3 and freezing and growth of dew condensation water adhering to the surface of the indoor heat exchanger 9. Therefore, it is possible to prevent the dew condensation water and the frozen ice 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.

When the opening / closing plate 19 is closed, the opening / closing plate 19 is closed.
The inner surface of No. 1 comes into contact with the air taken into the indoor unit 1, and the outer surface of the opening / closing plate 19 comes into contact with the air sent out from the air outlet.
For this reason, dew condensation is likely to occur due to the temperature difference between both sides of the opening / closing plate 19. However, it is more desirable to fix a heat insulating material such as a foamed resin or a hollow member having an air layer to the opening / closing plate 19 to prevent dew condensation.

Further, since the suction port 4c is opened by the opening / closing plate 19, a sufficient air volume can be obtained by opening the opening / closing plate 19 when the conditioned air is delivered from the first opening 5a in a substantially horizontal direction or in the downward direction. Can be secured. Therefore, it is possible to prevent a decrease in operating efficiency, and it is not necessary to increase the rotation speed of the blower fan 7 in order to secure a sufficient air volume, and it is possible to prevent an increase in noise. When the space between the indoor unit 1 and the ceiling in the room is narrow and the amount of intake air from the suction port 4a is small, the above effect becomes greater.

When the dehumidifying operation is performed by the air conditioner, similarly, the low temperature air dehumidified by the heat exchange with the indoor heat exchanger 9 is sent upward to obtain the same effect as the above. it can. Further, the air conditioner may be a reheat dry type dehumidifier having an evaporation section and a condensation section inside the indoor heat exchanger. That is, in the reheat dry type dehumidifying device, the air that has been cooled and dehumidified by heat exchange in the evaporator is heated in the condenser by heat exchange and sent out to the room. At this time, even if the temperature is raised in the condenser, it is possible to prevent the air having a temperature lower than the body temperature from constantly hitting the user.
