Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner having a blower fan for blowing sucked air inside an indoor unit.

[0002]

2. Description of the Related Art FIG. 15 is a schematic side sectional view of an indoor unit of a general air conditioner at present. A front suction port 4 (first suction port) and an upper suction port 5 are provided on the front surface of the cabinet 2 forming a mounting portion of the air conditioner to the wall of the indoor unit main body 1.
A front panel 3 provided with a (second suction port) is detachably attached. And the front panel 3
A substantially rectangular outlet 6 extending in the width direction of the main body 1 is formed in a gap between the lower end of the cabinet 2 and the lower end of the cabinet 2.

[0003] Thus, in the internal space of the main body 1 limited by the cabinet 2 and the front panel 3, a ventilation path 7 communicating from the front upper suction ports 4, 5 to the air outlet 6 is formed. Cabinet 2 in this ventilation path 7
A rotatable blower fan 8 is disposed in front of.
As the blower fan 8, for example, a cross flow fan can be suitably used.

An air filter 9 for collecting and removing dust contained in air sucked through the suction ports 4 and 5 is provided at a position inside the front panel 3 facing the inside.
Further, an indoor heat exchanger 10 is disposed between the blower fan 8 and the air filter 9 in the blower path 7, and when the air conditioner is cooled by operation of a refrigeration cycle (not shown). 10 is cooled to a temperature lower than the ambient temperature, and is heated to a temperature higher than the ambient temperature during heating.

[0005] In addition, at the lower part of the indoor heat exchanger 10 on the front of the cabinet 2, the indoor heat exchanger 10 is provided at the time of cooling or dehumidification.
There is provided a drain pan 11 for collecting the condensation that has dropped from the drain pan. In the vicinity of the air outlet 6 in the air blowing path 7, horizontal louvers 12 a, 1 that can change the angle in the vertical direction facing the outside are provided.
2b is provided, and a plurality of vertical louvers 13 whose angle can be changed in the left-right direction are provided in the back.

[0006] With the above configuration, when the operation of the air conditioner is started, the blower fan 8 is driven to rotate, and
Refrigerant from an outdoor unit (not shown) flows to the indoor heat exchanger 10 and circulates through a refrigeration cycle (not shown). As a result, the air outside the main body 1 is directed to the front, upper suction ports 4,
After being sucked into the main body 1 from the air filter 5, the air filter 9
As a result, dust contained in the air is removed.

After passing through the indoor heat exchanger 10, it is cooled or heated by exchanging heat with the refrigerant, and is urged by the rotation of the blower fan 8. The louvers 12a and 12b regulate the flow in the left and right and up and down directions, and are blown into the room from the outlet 6. The arrows in the figure indicate the flow of the air.

In the above-mentioned current air conditioner, it is necessary to circulate the air in the room immediately after the operation is started. The air that has been heat-exchanged by the heat exchanger 10 is blown out from the outlet 6 vigorously. Then, as the temperature difference between the room temperature and the set temperature decreases, the amount of air blown is gradually reduced, so that a fine and uniform temperature distribution is formed in the room.

However, if air is continuously blown from the air outlet 6 in a state where the temperature reaches around the set temperature during the dehumidifying operation or the cooling operation, a cold wind may always hit the user. In addition to giving discomfort, there has been a problem that the body temperature is locally lowered, which is not preferable for health.

The present invention has been made in view of the above-mentioned conventional problems, and provides comfort and health during a cooling operation or a dehumidifying operation by simply adding a simple function or configuration to a conventional air conditioner. It is an object of the present invention to provide an air conditioner capable of improving safety in the air conditioner.

[0012]

SUMMARY OF THE INVENTION To achieve the above object, the present invention provides an indoor heat exchanger in a ventilation path connecting first and second suction ports at an upper portion of a main body and an outlet at a lower portion of the main body. An air conditioner provided with a blower for sending air heat exchanged by the indoor heat exchanger through the outlet to the room, wherein a shutoff means for shutting off airflow from the outlet to the room is provided. It is characterized by.

According to this, when the air supply path to the air outlet is shut off by the shut-off means, air is sucked in from one of the first and second suction ports, and heat is exchanged in the process of passing through the indoor heat exchanger. After that, an unusual flow of air is generated which is energized by the blower and is blown from the other of the first and second suction ports through the blowing path.

The shut-off means has a rotatable vertical louver for adjusting a wind direction to a room disposed in the vicinity of the air outlet in the air blowing path to the left and right. When the air blower is rotated by approximately 90 ° to one side from a position parallel to the air blowing direction of the blower, the above-described cutoff can be performed only by adding a simple configuration to the vertical louver.

The shutoff means includes a rotatable vertical louver disposed in the vicinity of the air outlet in the air flow path and configured to adjust a wind direction to a room to the left and right, and to turn to the air outlet side from the vertical louver. It has a horizontal louver movably arranged to adjust the wind direction into the room up and down, and the air outlet can be closed, and the vertical louver is moved from a position parallel to the blowing direction of the blower to one side. When the air outlet is closed by the horizontal louver while being rotated by about 90 °, the above-mentioned shutoff can be easily performed using the vertical louver and the horizontal louver.

The blocking means is rotatably supported by the main body in the vicinity of the outlet, and is capable of taking a closed position and an open position of the air passage leading to the outlet by rotation. The shut-off can be easily performed by holding the rotating plate in the closed position.

Further, the blocking means has a movable member which is arranged near the air outlet and is capable of moving in and out of the air flow path. Can shut off.

Further, if the above-mentioned shut-off means is performed by the shut-off means when the temperature reaches around the set temperature during the cooling operation or during the dehumidifying operation, the cool air does not directly hit the user.

Particularly, in the dehumidifying operation, a reheat section in which a condensing section and an evaporating section coexist is formed inside the indoor heat exchanger, and the shutoff is performed by the shutoff means. We can draw out dehumidification ability to the maximum.

DESCRIPTION OF THE PREFERRED EMBODIMENTS <First Embodiment> A first embodiment of the present invention
An embodiment will be described with reference to the drawings. FIG.
FIG. 2 is a schematic side sectional view of the air conditioner according to the present embodiment, and FIG. 2 is a perspective view of a vertical louver of the air conditioner. In these drawings, members common to those of the conventional air conditioner shown in FIG. 15 are denoted by the same reference numerals, and detailed description thereof will be omitted.

A configuration characteristic of this embodiment will be described. A sufficient number of vertical louvers 13 for shutting off the air passage 7 are rotatably provided near the air outlet 6 in the air passage 7. As shown in FIG. 2 (a), the vertical louver 13 is a substantially rectangular plate-like member, and rotates integrally at substantially the center in the longitudinal direction of the lower end while maintaining the parallel positional relationship. Supported by the cabinet 2.

When the vertical louver 13 is rotated to a position substantially parallel to the lower end 2a of the cabinet 2 as shown in FIG. 2 (b), the front edge 13a and the rear edge 1a of the vertical louver 13 are rotated.
3b are close to each other.

Immediately after the cooling operation of the air conditioner having such a configuration is started, the vertical louver 13 is, for example, as shown in FIG.
As shown in (a), the air blower 8 is in a neutral position (a position parallel to the blow direction of the blow fan 8) in which the wind direction of the air sent from the blow fan 8 is not changed. 1 (a), an air flow is created as shown by the arrow, and the air sucked in from the front and upper suction ports 4 and 5 is cooled in the process of passing through the indoor heat exchanger 10 and passes through the ventilation path 7. Outlet 6.

The angle of the vertical louver 13 is not limited to the position shown in FIG. 2 (a), but may be fixed to an arbitrary angle or may be constantly varied, thereby providing a wind direction in a direction desired by the user. Can be fixed, and the wind direction can be swung in the left-right direction.

When the room temperature reaches near the set temperature as the cooling progresses, as shown in FIG.
Is rotated to cut off the blowing path 7 and the horizontal louver 1
2a and 12b rotate to close the outlet 6. Thereby, an air flow as shown by an arrow in FIG. 1B is created, and the air sucked in from the front suction port 4 is cooled in the process of passing through the indoor heat exchanger 10 and passes through the ventilation path 7. After being cooled again by passing through the indoor heat exchanger 10, the air is blown out from the upper suction port 5.

In this state, since the rotation speed of the blower fan 8 is reduced, gentle cool air is blown upward from the upper suction port 5. Therefore, there is no danger that the user will be disturbed by the cold wind, and sufficient safety can be secured in terms of health.

Note that the user may freely select such a mode according to his / her preference using a remote controller.

The shape of the vertical louver 13 is shown in FIG.
In addition to the substantially rectangular shape as shown in FIG. 3A, for example, as shown in FIGS. 3A and 3B, when the entire side surface of the vertical louver 13 is rotated so as to form a plane, the front edge portion thereof is formed. Any shape may be used as long as it has a corresponding relationship such that the rear edge portion and the rear edge portion are close to each other and cut off the blowing path 7 (see FIG. 1).

Alternatively, as shown in FIG. 4, a vertical louver (see FIG. 8) used for an existing product is provided with a narrow interval, so that the neutral position shown in FIG. When rotated by approximately 90 ° to the position shown, the air supply path 7 (see FIG. 1) may be overlapped and cut off. In this case, since off-the-shelf components can be used, the cost required for component manufacturing is reduced.

The same effect as described above can be obtained by performing the above-mentioned cutoff of the air supply path 7 during the dehumidifying operation. In this case, the dehumidifying operation is only the conventional weak cooling method (one of the dehumidifying methods, in which the rotational speed of the compressor and the rotational speed of the blower fan 8 are operated at a relatively low capacity during the cooling operation to dehumidify). Instead, the refrigerant evaporates in the indoor heat exchanger 10,
The evaporating section used as a so-called evaporator and the high-temperature refrigerant are conducted, and the condensing section used as a so-called condenser is mixed, and the air is cooled and dehumidified in the evaporating section in the process of passing air. However, it may be a so-called reheat dry type dehumidifying operation, such as reheating after passing through the condensing section or mixing and reheating high-temperature air passing through the condensing section.

<Second Embodiment> A second embodiment of the present invention will be described with reference to the drawings. FIG. 5 is a schematic side cross-sectional view of the air conditioner according to the present embodiment, and FIG. 6 is a partial perspective cross-sectional view around the rotary plate corresponding to FIG. In these drawings, members common to those of the conventional air conditioner shown in FIG. 15 are denoted by the same reference numerals, and detailed description thereof will be omitted.

A configuration characteristic of this embodiment will be described. A vertical louver 13 is provided near the outlet 6 in the blowing path 7.

Immediately after the cooling operation of the air conditioner having such a configuration is started, the rotating plate 14 is located at the position where it is stored in the recessed portion 2b of the cabinet 2 as shown by the broken line in FIG. By the rotation of the blower fan 8, an air flow similar to the arrow in FIG. 1A is created, and the air uniformly sucked from the front and upper suction ports 4 and 5 is removed by the indoor heat exchanger 1.
The air is cooled in the process of passing through the air outlet 0 and is blown out from the air outlet 6 through the air blowing path 7. In this case, since the rotating plate 14 is housed in the depressed portion 2b of the cabinet 2, the upper surface of the rotating plate 14 is not exposed from the front surface of the cabinet 2, and a smooth air flow is not hindered.

When the indoor temperature reaches near the set temperature when the cooling is advanced, the rotating plate 14 is moved to the position shown by the solid line in FIG.
Is rotated, and the blowing path 7 is shut off. As a result, FIG.
The air flow as shown by the arrow is created, and the air sucked from the front suction port 4 is cooled in the process of passing through the indoor heat exchanger 10, passes through the ventilation path 7, and returns to the indoor heat exchanger 1.
After passing through 0 and being cooled, it is blown out from the upper inlet 5. As shown in FIG. 7, the vertical louver 13 may be rotated together with the rotating plate 14, and in this case, the air outlet 6
Can be more reliably shut off.

In this state, since the rotation speed of the blower fan 8 has been reduced, gentle cool air is blown upward from the upper suction port 5. Therefore, there is no danger that the user will be disturbed by the cold wind, and sufficient safety can be secured in terms of health.

The user may freely select such a mode according to his / her preference using a remote controller.

The same effect as described above can be obtained by performing the above-mentioned cutoff of the air flow path 7 during the dehumidifying operation. In this case, the dehumidifying operation is only the conventional weak cooling method (one of the dehumidifying methods, in which the rotational speed of the compressor and the rotational speed of the blower fan 8 during the cooling operation are operated at relatively low capacity to dehumidify). Instead, the refrigerant evaporates in the indoor heat exchanger 10,
The evaporating section used as a so-called evaporator and the high-temperature refrigerant are conducted, and the condensing section used as a so-called condenser is mixed, and the air is cooled and dehumidified in the evaporating section in the process of passing air. However, it may be a so-called reheat dry type dehumidifying operation, such as reheating after passing through the condensing section or mixing and reheating high-temperature air passing through the condensing section.

<Third Embodiment> A third embodiment of the present invention will be described with reference to the drawings. 8 is a schematic side sectional view of the air conditioner according to the present embodiment, FIG. 9 is a partial perspective sectional view around the movable member corresponding to FIG. 8, and FIG.
FIG. 9 is a partial perspective sectional view of the periphery of the movable member of FIG. 8 as viewed from the back side. In these drawings, members common to those of the conventional air conditioner shown in FIG. 15 are denoted by the same reference numerals, and detailed description thereof will be omitted.

A configuration characteristic of this embodiment will be described. A vertical louver 13 is provided near the outlet 6 in the blowing path 7.
Is provided rotatably. As shown in FIGS. 8 and 9, behind the vertical louver 13, as shown in FIGS. 8 and 9, the closed position of the air supply path 7 which is operated by a drive source (not shown) and reaches the air outlet 6 (the position indicated by a solid line in FIG. 8). ) And an open posture (a position shown by a broken line in FIG. 8), a movable member 15 made of a single plate
Are provided in the air passage 7 so as to be able to come and go.

A part on the back side of the movable member 15 includes:
As shown in FIG. 10, a gear meshing portion 15a that meshes with a gear 18 attached to the tip of a shaft (not shown) that is rotationally driven by a drive source (not shown) is formed by corrugating, and is a movable member. Reference numeral 15 is adapted to be inserted into and removed from the groove 2 c of the cabinet 2 depending on the rotation direction of the gear 18. It is desirable that the protruding distal end of the movable member 15 has a sectional shape that is flush with the front surface of the cabinet 2 when the movable member 15 is housed in the groove 2c.

Immediately after the cooling operation of the air conditioner having such a configuration is started, the movable member 15 is located at a position accommodated in the groove 2c of the cabinet 2 as shown by a broken line in FIG. By the rotation of the fan 8, an air flow similar to the arrow in FIG. 1A is created, and the air sucked from the front and upper suction ports 4 and 5 passes through the indoor heat exchanger 10 during the process. It is cooled and passes through the air outlet 6
Blown out from. In this case, since the movable member 15 is housed in the groove 2c of the cabinet 2, the movable member 1
The upper end of 5 is not exposed from the front surface of the cabinet 2 and smooth air flow is not hindered.

When the indoor temperature reaches near the set temperature as the cooling progresses, the gear 18 rotates in the forward direction by the drive source (not shown), and as shown by the solid line in FIG. The movable member 15 protrudes inside, and the blowing path 7 is shut off. As a result, an air flow as shown by the arrow in FIG. 8 is created, and the air sucked from the front suction port 4 is supplied to the indoor heat exchanger 1.
After being cooled in the process of passing through 0, passing through the ventilation path 7 and passing through the indoor heat exchanger 10 again, it is blown out from the upper inlet 5. In addition, as shown in FIG. 11, the vertical louver 13 may be rotated together with the movable member 15, and in this case, the ventilation path 7 reaching the outlet 6 can be more reliably shut off.

In this state, since the rotation speed of the blower fan 8 is reduced, gentle cool air is blown upward from the upper suction port 5. Therefore, there is no danger that the user will be disturbed by the cold wind, and sufficient safety can be secured in terms of health.

The user may freely select such a mode according to his / her preference by using a remote controller.

The same effect as described above can be obtained by performing the above-mentioned cutoff of the air flow path 7 during the dehumidifying operation. In this case, the dehumidifying operation is only the conventional weak cooling method (one of the dehumidifying methods, in which the rotational speed of the compressor and the rotational speed of the blower fan 8 during the cooling operation are operated at relatively low capacity to dehumidify). Instead, the refrigerant evaporates in the indoor heat exchanger 10,
The evaporating section used as a so-called evaporator and the high-temperature refrigerant are conducted, and the condensing section used as a so-called condenser is mixed, and the air is cooled and dehumidified in the evaporating section in the process of passing air. However, it may be a so-called reheat dry type dehumidifying operation, such as reheating after passing through the condensing section or mixing and reheating high-temperature air passing through the condensing section.

<Fourth Embodiment> A fourth embodiment of the present invention will be described. FIG. 12 is a schematic side sectional view of the air conditioner according to the present embodiment, and FIG. 13 is a partial perspective sectional view around the movable member corresponding to FIG. In these drawings, members common to those of the conventional air conditioner shown in FIG. 15 are denoted by the same reference numerals, and detailed description thereof will be omitted.

A vertical louver 13 is rotatably provided near the air outlet 6 in the air blowing path 7. This vertical louver 1
As shown in FIGS. 12 and 13, at a position deeper than 3, as shown in FIGS. 7 is provided with a rotating plate 16 made of a single plate that can take an open position (see FIG. 12A) and a closed position (see FIG. 12B).

Immediately after the cooling operation of the air conditioner having such a configuration is started, as shown in FIGS. 12 (a) to 13 (a), the rotating plate 16 causes the air passing through the air passage 7 to flow. It is fixed at a position that does not impede the smooth flow, and the rotation of the blower fan 8 creates an air flow as shown by the arrow in FIG. 12A and is sucked from the front and upper suction ports 4 and 5. The air is cooled in the process of passing through the indoor heat exchanger 10, and is blown out of the outlet 6 through the blowing path 7.

When the cooling progresses and the indoor temperature reaches around the set temperature, as shown in FIGS. 12 (b) to 13 (b), the rotating plate 16 rotates about the shaft 17, Ventilation path 7
Is shut off. As a result, an air flow as shown by the arrow in FIG. 12B is created, and the air sucked from the front suction port 4 is cooled in the process of passing through the indoor heat exchanger 10 and passes through the air passage 7. After passing through the indoor heat exchanger 10 and cooled again, the air is blown out from the upper suction port 5.
As shown in FIG. 14, the vertical louver 13 may be rotated together with the rotary plate 16, and in this case, the air flow path 7 reaching the outlet 6 can be more reliably shut off.

In this state, since the rotation speed of the blower fan 8 is reduced, gentle cool air is blown upward from the upper suction port 5. Therefore, there is no danger that the user will be disturbed by the cold wind, and sufficient safety can be secured in terms of health.

The user may freely select such a mode according to his / her preference using a remote controller.

The same effect as described above can be obtained by shutting off the air supply path 7 during the dehumidifying operation. In this case, the dehumidifying operation is only the conventional weak cooling method (one of the dehumidifying methods, in which the rotational speed of the compressor and the rotational speed of the blower fan 8 are operated at a relatively low capacity during the cooling operation to dehumidify). Instead, the refrigerant evaporates in the indoor heat exchanger 10,
The evaporating section used as a so-called evaporator and the high-temperature refrigerant are conducted, and the condensing section used as a so-called condenser is mixed, and the air is cooled and dehumidified in the evaporating section in the process of passing air. However, it may be a so-called reheat dry type dehumidifying operation, such as reheating after passing through the condensing section or mixing and reheating high-temperature air passing through the condensing section.

[0053]

As described above, according to the present invention, the air conditioner can be operated in a state where the air outlet is shut off by using the shutoff means. Therefore, when the blower is rotationally driven in this state, indoor air is sucked in from one of the two outlets and an unusual airflow is blown out from the other. Thereby, since the cool air is not blown out from the outlet at the lower part of the main body in the vicinity of the set temperature in the cooling operation or in the dehumidifying operation, a fine and comfortable temperature distribution can be formed in the room. As a result, an air conditioner with improved user comfort and health safety can be provided.
