Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor unit of an air conditioner installed in a room and blowing out heat-exchanged air into the room.

[0002]

2. Description of the Related Art Most of indoor units of an air conditioner are
There is only one outlet, and the air that has undergone heat exchange from this outlet,
That is, cold air and hot air are blown into the room. However, there is a limit to the area where the air is sent when there is only one outlet.

Therefore, temperature unevenness is likely to occur in the room to be cooled or heated, and the comfort is not so good. In particular, the temperature variation in the vertical direction in the room is large, and it cannot be said that the room is excellent in cooling and heating.

Therefore, recently, as shown in FIG. 7 (a), two air outlets b and c are provided at the upper and lower portions of the front surface of the casing a, and two upper and lower crossflows in the casing a. It has been proposed that fans d, d are provided so that the air after heat exchange that has passed through the indoor heat exchanger e is blown out into the room from the outlets b, c.

More specifically, one of the cross flow fans d, d of the indoor unit shown in FIG. 7 (a) is normally rotated and the other is reversely rotated by driving a fan motor installed for each fan (not shown). Is done. Further, around these cross-flow fans d, d, there is formed an air passage f which connects the suction port i provided in the middle of the front face of the casing a and the respective blow-out ports b, c with each other. The air after heat exchange that has passed through the indoor heat exchanger e by the fan d is blown from the upper outlet b to the upper side of the room, and after the heat exchange after passing through the indoor heat exchanger e by the lower crossflow fan d. The air was blown from the lower outlet c to the lower side of the room.

In addition, an indoor unit of this type is shown in FIG.
As shown in FIG. 7B, the indoor unit configured as shown in FIG. 7A is installed vertically so that the axes of the cross-flow fans d are vertical, and the cross-flow fan (shown in the figure) is arranged on the left side. Of the heat-exchanged air sucked from the front suction port j to the left side of the room from the left outlet g, and the cross-flow fan (not shown) arranged on the right side also performs the heat-exchanged air. There is also one in which the air is blown from the outlet h on the right side toward the right side in the room.

[0007]

According to such an air conditioner, since the heat-exchanged air is blown out from a plurality of outlets in different directions, the temperature unevenness in the room is reduced, but one casing is used. Two cross-flow fans d in a
Since all the d and two fan motors are provided, there is a problem that the structure of the indoor unit becomes complicated.

Moreover, this indoor unit has a larger diameter than that of an indoor unit provided with one cross flow fan.
Since the amount of air blown is smaller than when using a single cross-flow fan, there is the inconvenience that the indoor heat exchanger e cannot be enlarged due to space constraints and the shape of the air passage cannot be set appropriately. There is a problem that air conditioning capacity decreases.

The present invention has been made in view of such circumstances, and its purpose is to reduce the temperature unevenness in the room with a simple structure without lowering the cooling and heating capacity. An object is to provide an indoor unit of an air conditioner.

[0010]

In order to achieve the above object, an indoor unit according to a first aspect of the present invention is provided with a casing around a cross flow fan, and both sides of the casing in the radial direction sandwiching the cross flow fan. One of the two units is provided with a suction port and the other is provided with a blowout port, and a first unit is provided. Similarly, the first unit is provided with a blowout port on the opposite side to the first unit,
A second unit having a suction port is provided on the other side, and an electric component unit having a fan motor built therein is further provided. The first unit, the second unit, and the electric component unit are connected to each other. The cross-flow fans are connected in the axial direction, and the cross-flow fans of the first and second units are connected to the output shaft of the fan motor of the electrical unit.

The indoor unit according to a second aspect of the present invention has the first unit and the second unit interconnected with each other according to the first aspect of the present invention so as to have a laterally long blowout distribution in order to effectively reduce the temperature unevenness. The unit and the electrical equipment unit were installed in the room so that the axis of the cross flow fan was horizontal.

The indoor unit according to a third aspect of the present invention has the first unit and the second unit interconnected with each other according to the first aspect, so as to have a vertically long blowout distribution in order to effectively reduce the temperature unevenness. The unit and the electrical equipment unit were installed in the room so that the axis of the cross flow fan was substantially vertical.

In the indoor unit according to the fourth aspect, the first unit and the second unit are further provided so that the first unit and the second unit have a completely common structure.
A rotatable fan casing and a tongue are provided between the first position and the second position in the circumferential direction of the cross fan, which are different from each other in the circumferential direction, and the fan casing and the tongue have the first position and the second position. The structure is such that the suction side and the blowout side of the cross flow fan are set according to the position selection.

[0014]

The indoor unit according to claim 1 is a fan unit.
When the motor is driven, the cross flow fan rotates for each unit. Then, blown air is blown out in different directions from the respective outlets of the first unit and the second unit, that is, the plurality of outlets. As a result, blown air reaches the various parts of the room, so that the temperature unevenness in the room is corrected.

Moreover, since there is one cross-flow fan for each unit, the structure of each unit, that is, the structure of the indoor unit, is simpler than the structure in which a plurality of cross-flow fans are provided in one casing.

In addition, if there is one cross-flow fan for each unit, it is possible to use a fan with a sufficiently large outer diameter in each unit, and there are few space restrictions, so that the indoor heat It is possible to appropriately set the size of the exchanger and the shape of the air passage, and it is possible to prevent the cooling and heating capacity from decreasing. According to the indoor unit of the second aspect, the blown air is blown out from the plurality of outlets in the up and down direction in the room with a horizontally long blowout distribution. Thereby, the temperature unevenness in the room is effectively reduced, and the entire room is effectively air-conditioned. According to the indoor unit of the third aspect, the blown air is blown out from the plurality of outlets in the left-right direction in the room with a vertically long blowout distribution. Thereby, the temperature unevenness in the room is effectively reduced, and the entire room is effectively air-conditioned.

According to the indoor unit of claim 4,
When the fan casing and the tongue are set to the first position from the turning operation, the suction side is formed on one of both sides sandwiching the cross flow fan, and the blow side is formed on the other side.
The unit will be constructed.

Also, the fan casing and the tongue portion are
When set to the position, this time, on the contrary, the blowing side is formed on one of both sides sandwiching the cross-flow fan, and the suction side is formed on the other side to form the second unit. That is,
It is possible to configure the first unit and the second unit with exactly the same unit structure.

By changing the direction of the wind by such fan casing and movement of the tongue, for example, both upward blows,
It is possible to change the blowing mode according to preference, such as three types of both downward blowing and one blowing each. Moreover, the common manufacturing of parts makes the manufacturing cost low.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention shown in FIGS.
A description will be given based on the embodiment.

FIG. 1 shows an air conditioner to which the present invention is applied. Reference numeral 1 is an indoor unit installed horizontally on the upper wall of the room A, and 40 is an outdoor unit installed outdoors.

The indoor unit 1 is a blow-out unit 2 directly below.
(Corresponding to the first unit), the upper blowing unit 3 (second
(Corresponding to the unit of 1) and the electrical unit 30 are combined one by one. That is, the blow-off unit 2 just below has a structure as shown in the cross-sectional view of FIG.

Explaining directly below the blow-out unit 2,
Reference numeral 4 denotes a box-shaped casing, the right end of which is open. On the front side of this casing 4, the coating is made from the upper front side.
A suction port 5 is provided in a portion extending to the upper part through the corner. Reference numeral 6 denotes a suction grill provided at the suction port 5. An air outlet 7 is provided on the lower front side of the casing 4.

A transverse fan 8 is arranged in the middle of the casing 4 so as to extend in the left-right direction. Cross-flow fan 8
For example, a structure that blows air from above to below the cross flow fan 8 by rotating in the direction of the arrow (counterclockwise direction) in the figure is used. A suction passage 9 is provided in the suction port 5 located above the cross flow fan 8 from above. Further, a blow-out passage 10 having a shape suitable for direct blow-off is provided at the blow-out port 7 below the lower side of the cross flow fan 8. By these suction passage 9 and blow-out passage 10, the air above the room is sucked from the suction opening 5 located at one of the positions sandwiching the cross flow fan 8, and is blown out just below the casing 4 from the blowing opening 7 also located at the other side. The wind path 11 is configured. In addition, 12 is an air passage 11
Is a casing portion, and 13 is a nose of the cross flow fan 8.
It is the tongue that forms the mouth.

An indoor heat exchanger 14 is provided in the suction passage portion inside the suction port 5 so that the indoor air heat-exchanged by the indoor heat exchanger 14 can be blown out into the room. Reference numeral 15 denotes a drain pan disposed below the indoor heat exchanger 14. The upper outlet unit 3 is shown in FIG.
The structure is as shown in the sectional view of FIG. The upper blow-off unit 3 has the same configuration as that of the above-mentioned blow-off unit 2 except for the air passage system.

Therefore, with respect to the same portion as the immediately below blow-off unit 2, the suffix "a" is added to the suffix of the number immediately below the blow-off unit 2 and the description thereof will be omitted, and a different air passage system will be explained.

That is, the casing 4a has a box shape with an open left end. On the front surface side of the casing 4a, for example, an air outlet 21 is provided with the same opening shape as that of the suction port of the just below air outlet unit 2. Further, on the lower front side of the casing 4a, for example, a suction port 22 is provided with the same opening shape as that of the blowout port. That is, the outlet 2
1, the suction port 22 is for each suction of the blow-off unit 2 just below,
It is provided at a position opposite to the blowing position. It should be noted that the cross-flow fan 8a is the same as the above-mentioned cross-flow fan 8a and the blade tilt direction,
Both directions of rotation are the same.

A suction passage 23 is provided in the suction port 22 below the lower side of the cross flow fan 8a.
A blowout passage 24 having a shape suitable for obliquely upward blowing is provided at the blowout port 21 above the crossflow fan 8a. Due to the suction passage 23 and the blow-out passage 24, the cross-flow fan 8 is opposite to the case of the above-mentioned blow-down unit 2 directly below.
An air passage 25 is formed that sucks in the air just below from the suction port 22 that is the other of the positions sandwiching the space and blows it out obliquely above the casing 4a from the blowout port 21 that is the one.

On the other hand, as shown in FIG. 3, the electrical unit 30 has a casing 31 having a flat box-like outer shape in which the width dimensions of the casings 4 and 4a are shortened. In this casing 31, a single biaxial fan motor 32 and electric components (not shown) necessary for controlling the operation of the air conditioner are incorporated.

The fan motor 32 is arranged so as to be coaxial with the shafts of the cross flow fans 8 and 8a of the just-below blow unit 2 and the above blow unit 3. This fan motor 3
Each end portion of the second output shaft 32a projects to the outside from the left and right walls 31a of the casing 31, which serves as a partition wall from the units 2 and 3.

The casings 4, 4a and 31 of the respective units thus constructed are arranged with their front faces aligned so that the cross flow fans 8 and 8a are coaxially arranged along the axis, for example, directly below the blowing unit 2, Electrical unit 30, upper blow unit 3
Are connected in series in this order. Also, fan motor 32
Each end of the output shaft 32a is connected to the shaft of each adjacent cross-flow fan 8 via a joint structure (not shown) so as to rotate each cross-flow fan 8, 8a in the direction of the arrow in the figure. . By connecting the two cross flow fans 8 and 8a to the one fan motor 32, an elongated indoor fan 27 is constructed.

By combining the units 2, 30 and 3 as a module, the indoor unit 1 having a multi-blow-out direction capable of performing both an upward blow and a downward blow with one driving source is provided. I am configuring. With the back surface of such an assembly as an installation surface, the entire indoor unit is installed on the upper wall surface of the room A so that the axes of the cross flow fans 8 and 8a are horizontal. The indoor heat exchangers 14, 14a of the indoor unit 1 are connected by refrigerant pipes 26, 26 (only shown in FIG. 1). Then, the indoor unit 1 is connected to the outdoor unit 40.

That is, in the outdoor unit 40, a circuit is provided in which the compressor 41 is connected to the outdoor heat exchanger 43 and the expansion valve 44 in this order via the four-way valve 42. Then, this circuit is connected to the indoor heat exchangers 14 and 14a of the indoor unit 1 via the connecting pipes 45 and 45 that pass between the indoor unit 1 and the outdoor unit 40, and a heater capable of cooling and heating operation is connected. It constitutes a toppump type refrigeration cycle. In addition, 43a is an outdoor fan provided in the outdoor heat exchanger 43. Next, the operation of the air conditioner thus configured will be described. For example, when heating
Turn on the heating button on the operation panel (not shown).

Then, the four-way valve 42 is switched to the heating side,
The compressor 41 operates. As a result, the compressed refrigerant discharged from the compressor 41 circulates through the indoor heat exchangers 14 and 14a, the expansion valve 44, and the outdoor heat exchanger 43 to form a heating cycle.

On the other hand, in accordance with the above heating operation, the fan motor 32 is excited and the rotation is output to both ends 32a.
As a result, the cross flow fans 8 and 8a are in the same direction,
For example, it is rotated counterclockwise.

Then, in the blow-out unit 2 directly below, the room A
The air above is sucked from the suction port 5 and taken into the air passage 11. When this air passes through the indoor heat exchanger 14, it exchanges heat with the indoor heat exchanger 14 to become hot air, and then this hot air is blown out from the air outlet 7 to a direction directly below the indoor unit 1. It

In the upper outlet unit 3, the air below the room A is sucked through the suction port 22 and taken into the air passage 25. Then, as in the case of the blowout unit 2 just below, when this air also passes through the indoor heat exchanger 14a, it exchanges heat with the indoor heat exchanger 14a to become warm air, and thereafter,
The warm air is blown from the outlet 21 to above the indoor unit 1 in the direction opposite to the direction directly below the blowout unit 2. As a result, the blowing air is blown out in the laterally long blowing distribution in the upward and downward directions of the room A, and the warm air reaches each part of the room A. Therefore, the temperature unevenness in the room A can be corrected.

Further, according to the indoor unit 1, the direct blowing of the warm air is performed right below since the blowing of the conventional air conditioner is directed obliquely downward, while the blowing mode is most suitable for the blowing directly below. Therefore, there is an advantage that the amount of warm air reaching the floor during heating is increased.

Further, since the indoor unit 1 has a structure in which one cross flow fan 8 and 8a is provided for each of the units 2 and 3 which are the modules, the unit can be freely arranged into a plurality of cross flow in one conventional casing. This is simpler than the structure in which a fan is provided. Moreover, since only one fan motor 32 is required,
There is also an advantage that the electric component unit 30 is also small.

Further, since one cross-flow fan 8, 8a is provided for each unit 2, 3, there is little space limitation, and a cross-flow fan with a sufficiently large outer diameter is used for each unit 2, 3. It is possible to use the conventional single case
Compared to the structure in which two cross-flow fans are installed in the single unit, the amount of air blow can be increased (in the case of the same unit size, one cross-flow fan with a larger outer diameter than when two cross-flow fans with smaller diameters are used. Because the fan blows more air). Moreover, since the sizes of the indoor heat exchangers 14 and 14a can be increased, and the air passages 11 and 25 can be set to have an appropriate shape according to the air flow, there is no decrease in heating (cooling) capacity.

In addition, the indoor unit 1 is installed on the wall surface so that the axes of the cross-flow fans 8a, 8a are horizontal, and the warm air is blown out from the two outlets 7, 21 on the left and right in a laterally long blowout distribution. The room A was blown up and down.
It is possible to effectively reduce the temperature unevenness of the room and effectively heat the entire room.

In addition, as in one embodiment, the electrical equipment unit 4
The structure in which the blow-down unit 2 and the upper blow-out unit 3 are provided so as to sandwich the same electrical equipment unit 40 on both sides of 0 is a blowout port of the upper blow-out unit 3 on the right side due to the distance between the units obtained by installing the electrical equipment unit 40. The warm air (cold air) blown from 21 is immediately sucked in through the suction port 5 of the right-side blow-off unit 2 on the left side, or immediately under the blow-off unit 2
The warm air (cold air) blown out from the blow-out port 7 of No. 2 is immediately sucked from the suction port 22 of the upper blow-out unit 3 without producing a short-circuit kit.

It should be noted that in one embodiment, the blow-out unit 2 directly below,
Although the indoor unit 1 in which the upper blow-out units 3 are combined one by one has been described, the number of the lower blow-out units 2 and the upper blow-out units 3 to be combined is not limited to this, and may be increased.
An example of this is shown in FIG. 4 as the second embodiment.

That is, in this embodiment, the upper blow-off unit 3, the blow-down blower unit 2, the electrical unit 30, and the upper blow-off unit 3 are cross-flow fans 8, 8a in this order.
The indoor unit 1 is configured by connecting in series in the axial direction. FIG. 5 shows a third embodiment of the present invention.

In this embodiment, the indoor unit 1 is not installed horizontally such that the axes of the cross flow fans 8 and 8a are horizontal, but the indoor unit 1 is set so that the axes of the cross flow fans 8 and 8a are substantially vertical. Is installed vertically.

In such an installation, warm air (cold air) is blown up and down in the room A in a vertically long blowout distribution from the two outlets 7 and 21 at the top and bottom, so that it is the same as the previous horizontal installation. ,
The temperature unevenness in the room A can be effectively reduced, and the entire room can be effectively heated. 4 and 5, the same parts as those in the first embodiment described above are designated by the same reference numerals and the description thereof is omitted. FIG. 6 shows a fourth embodiment of the present invention.

In the present embodiment, the structure directly below the blow-out unit 2 and the upper blow-out unit 3 are not constituted by adopting a different structure, but the common blow-out unit 2 just below the blow-out unit 2 is provided.
