Description

  The present invention relates to a floor-mounted air conditioner, and more specifically, allows conditioned air to be blown out around a main body installed along a central part or a wall surface of an air-conditioned room, and a lower part of the main body. The present invention relates to a structure capable of improving the blowing performance of an air flow sucked from a side suction port and blown from an upper side blower outlet.

  The conventional floor-mounted air conditioner has a suction grill provided on the entire circumference of the lower surface of the air conditioner main body, a heat exchanger provided on the inner circumference of the suction grill, and an upward direction of the heat exchanger. The provided blower motor, the blower, the air outlet provided on the entire side of the upper surface of the air conditioner body, the top plate provided at the upper part of the air outlet and perpendicular to the air flow, and the center of the top plate It is composed of a shaft, a sealing plate that partially seals the space between the top plate and the outlet, and a groove that slides the sealing plate. In some directions, air conditioning is not required, and the sealing plate can be slid along the groove so that the non-air-conditioning unit can be freely selected (for example, see Patent Document 1).

  However, as shown in FIG. 1 to FIG. 3 attached to Japanese Patent Laid-Open No. 2001-153388, the blower is composed of an axial fan, and the air sucked from the suction grill and blown out from the blower outlet is tempered. After hitting the board (collision), it is blown out to the entire side of the upper part of the main unit. There was a risk of causing this.

  In addition, since the air conditioner main body has a configuration in which the upper and lower surfaces are closed and formed in a cylindrical shape, for example, it is not always seated when installed along the wall surface of the air-conditioned room or in the corner portion. In this case, for example, forming the air conditioner body in a quadrangular shape when viewed from above is suitable for installing along the wall surface of the air-conditioned room.

JP 2001-153388 A (pages 1 to 4 and FIGS. 1 to 3)

  According to the present invention, the suction port is provided on the lower side surface of the main body, the air outlet is provided on the upper side surface, and the air passage connecting the air inlet and the air outlet is linked to the filter, the heat exchanger, and the fan motor. Since the centrifugal fan is provided so as to be linked to the lower part of the fan motor and face the air outlet, the direction of the suction port and the air outlet is not limited, and the predetermined direction It is possible to set the non-air-conditioning part in a direction where air conditioning is not necessary, and the air hits the top plate (impacts) and then blows out to the entire side of the top of the main unit. This eliminates the possibility that the air blowing performance will be significantly reduced, and the floor-mounted air conditioner that does not cause the occurrence of noise.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail as examples based on the attached drawings.
FIG. 1 is an explanatory view of an air conditioner according to the present invention, in which (A) is a longitudinal sectional view, (B) is a transverse sectional view, (C) is a diagram showing a second example of a heat exchanger, and (D) is a heat FIG. 2 is an explanatory view of an air conditioner according to the present invention, FIG. 2 (A) is a perspective view, FIG. 2 (B) is a main part perspective view showing a cold air blowing direction, and FIG. ) Is a perspective view of the main part showing the blowing direction of warm air, (D) is an enlarged view of part B shown in (A), and FIG. 3 is an explanation showing an embodiment in which the air conditioner body is installed on the floor surface. In the figure, (A) is a plan view showing a state installed in the center of the air-conditioned room as Example 1, and (B) is a plane showing a state installed at the corner of the air-conditioned room as Example 2. (C) is a top view which shows the state installed along the wall surface of an air-conditioned room as Example 3. FIG.

  As shown in FIGS. 1 (A) and 1 (B), a floor-mounted air conditioner according to the present invention is formed in a rectangular tube shape in which an air conditioner body 1 is closed at the upper and lower surfaces, and a lower part. A suction port 2 is provided on the side surface, and an air outlet 3 is provided on the upper side surface.

  A removable filter 4, a heat exchanger 5, and a centrifugal fan 8 linked to the fan motor 6 are provided in the air passages connecting the suction port 2 and the blowout port 3, respectively.

  As shown in FIG. 1A, the fan motor 6 is provided in the upper part of the main body 1 by a mounting member 7 with the drive shaft 6a vertical, and the centrifugal fan 8 is provided at the lower end of the drive shaft 6a. It is the structure which is provided so that it may face the said blower outlet 3 while linking with a part.

  As a result, the suction air sucked from the suction port 2 is subjected to heat exchange by the heat exchanger 5 after the dust contained in the air is removed by the filter 4 and driven by the fan motor 6. Further, the centrifugal fan 8 sends the air to the outlet 3.

  At this time, since the centrifugal fan 8 is linked to the lower part of the fan motor 6 and is provided so as to face the blower outlet 3, the centrifugal fan 8 is sucked from the inlet 2 and exchanged heat with the heat exchanger 5. The blown air is efficiently guided to the outlet 3 by the centrifugal fan 8.

  That is, as explained in the above-mentioned prior art, “after the air hits (collises) the top plate”, it is no longer blown to the entire side of the upper side of the main body, and the air blowing performance is greatly reduced. There is no fear, and there is no possibility of causing noise.

  Further, as shown in FIGS. 2 (A) and 2 (D), the suction port 2 is composed of a plurality of horizontal rails 2a whose tips are inclined downward, whereby the suction port 2 Thus, the user's line of sight from above can be effectively blocked so that the inside of the main body 1 cannot be seen from 2, and the design is not impaired.

  Then, by tilting the front ends of the plurality of horizontal rails 2a downward, as shown by the arrow a in FIG. 1A, room air near the floor surface of the air-conditioned room A is sucked upward. After passing through the filter 4 and the heat exchanger 5, as shown by an arrow b in FIG. 1A, the air is blown out from the air outlet 3 to the air-conditioned room A. The blown air blown out from the blowout port 3 can prevent a so-called short circuit phenomenon in which a part of the blown air is directly sucked into the suction port 2.

  The air outlet 3 is provided on the entire circumference of the lower side surface of the main body 1, while the air outlet 3 deflects the air direction in the vertical direction and the vertical air direction deflecting plate 9 that opens and closes the air outlet 3 rotates. The structure is freely provided.

  The air blown out from the blowout port 3 is guided by the centrifugal fan 8 while maintaining a predetermined flow velocity without hitting (collision) with the top plate. 9 can effectively deflect the wind direction.

  For example, at the time of cooling operation, as shown in FIG. 2B, by rotating the up-and-down air direction deflecting plate 9 upward or horizontally, the blown cold air flow blown from the blow-out port 3 is changed into an air-conditioned room. It becomes possible to spread to every corner of A and to perform comfortable air conditioning.

  As shown in FIGS. 2 (B) and 2 (C), the vertical air direction deflecting plate 9 is provided at the air outlet 3 on the entire lower side surface of the main body 1 to change the vertical air direction. The air outlet 3 can be deflected and a part of the air outlet 3 can be opened and closed.

  At the time of heating operation, as shown in FIG. 2C, the warm air flow blown out from the blow-out port 3 is converted into the floor surface of the air-conditioned room A by rotating the vertical wind direction deflecting plate 9 downward. So that it can be effectively blown out toward the floor, and so-called foot heating can be effectively realized.

  Alternatively, as shown in FIGS. 3 (A) to 3 (C), the main body 1 is satisfactorily installed at an arbitrary position corresponding to the size and planar shape of the air-conditioned room A, and the air outlet 3 As shown by the arrow b, the direction of the blown-out air blown out from the air can be arbitrarily set so that effective air conditioning can be performed.

  For example, as shown in FIG. 3A as Example 1, when the main body 1 is installed on the center floor surface of the air-conditioned room A, the air blown out from the air outlet 3 is indicated by an arrow b. So that it can be blown out in four directions.

Further, as shown in FIG. 3B as Example 2, when the main body 1 is installed on the floor surface of the corner portion of the air-conditioned room A, the blown air blown out from the blowout port 3 is indicated by an arrow b. As shown, it can be blown out in two directions.
At that time, the air outlet 3 facing the wall surface of the air-conditioned room A may be closed by the up-and-down air direction deflecting plate 9.

Further, as shown in FIG. 3C as Example 3, when the main body 1 is installed on the floor so as to be along one wall surface of the air-conditioned room A, the air blown out from the air outlet 3 Can be blown out in three directions as indicated by an arrow b.
At that time, the air outlet 3 facing the wall surface of the air-conditioned room A may be closed by the up-and-down air direction deflecting plate 9 as in the above two examples.

  Next, as shown in FIG. 1A, the heat exchanger 5 is provided at the upper part of the suction port 2 and at the lower part of the blower outlet 3, and the filter 4 is connected to the suction port 2. The structure provided horizontally and detachably between the heat exchanger 5 will be described.

  That is, the filter 4 and the heat exchanger 5 are provided above the suction port 2, and the centrifugal fan 8 facing the blowout port 3 is provided above the heat exchanger 5. As a result, the main body 1 can be configured as a floor-standing air conditioner formed in a vertically long shape. As described above, the main body 1 can be arbitrarily set in accordance with the size, planar shape, etc. of the air-conditioned room A. It is possible to perform effective air conditioning by arbitrarily setting the direction of the blown air blown out from the blowout port 3.

  Since the filter 4 is configured to be horizontally and detachably provided between the suction port 2 and the heat exchanger 5, the filter 4 is accommodated in the main body 1 shown in FIG. In the maintenance, for example, the suction port 2 is configured so that the suction grill 2 can be opened and closed (rotated) and detachably attached to the location. It can be attached and detached by opening and closing.

  At this time, the suction grill is configured such that at least one suction port 2 of the suction ports 2 formed on the four surfaces of the main body 1 is opened and closed, and the filter 4 is opened and closed by opening and closing the suction port 2. It should be possible to insert and remove.

  Moreover, as shown in FIG. 1A as a first example, the heat exchanger 5 is installed in an inclined manner in an air passage that connects the suction port 2 and the blowout port 3, for example, horizontally. While being able to install what was larger than the case where it installs, it is suitable when comprising the said main body 1 as a floor-standing type air conditioner formed in the vertically long shape.

  Alternatively, as shown in FIG. 1C as a second example, when the heat exchanger 5 is formed in an inverted V-shaped cross section, the capacity of the heat exchanger 5 is increased to improve the heat exchange capability. As shown in FIG. 1D as a third example, when the heat exchanger 5 is formed in an M-shaped cross section, the capacity of the heat exchanger 5 is further increased. In addition, the vertical dimension when the heat exchanger 5 is installed in the main body 1 can be suppressed, and the height dimension of the main body 1 can be reduced.

  As described above, according to the air conditioner of the present invention, the air sucked from the suction port 2 and heat-exchanged by the heat exchanger 5 is cooled by the axial flow fan as described above. Rather than flowing into the air-conditioned room A after hitting the plate, the centrifugal fan 8 efficiently sends the air to the air outlet 3 and blows out into the air-conditioned room A. As a result, the main body 1 can be satisfactorily installed on the floor surface with the main body 1 along the corner or one wall surface of the air-conditioned room A.
