Description

  The present invention relates to a configuration of an air outlet of a floor-mounted air conditioner, and more particularly to an apparatus for opening and closing the air outlet.

  Conventionally, this type of floor-mounted air conditioner has built-in up / down / left / right wind direction change blades, and a shutter for opening / closing the air outlet is arranged on the outer wall thereof, and the air outlet is closed when stopped (for example, see Patent Document 1). ).

  6A and 6B are perspective views of a conventional floor-mounted air conditioner described in Patent Document 1, in which FIG. 6A shows a state when stopped, and FIG. 6B shows a state when operating. As shown in FIGS. 5A and 5B, the conventional air conditioner has a vertically long, substantially rectangular parallelepiped cabinet 13, and a heat exchanger (not shown) and a blower ( The front panel 14 is coupled to the center of the front surface of the cabinet 13, and the operation unit 1 that controls the air conditioner is provided at the lower end of the front panel 14. A suction port 5 for sucking room air into the air conditioner by a blower is formed in the lower front portion of the cabinet 13, and a blower outlet 4 for discharging the air heat-exchanged by the heat exchanger is formed in the upper front portion of the cabinet 13. Is formed. The discharged air is changed in wind direction up and down by a plurality of wind direction changing blades 7.

In the conventional air conditioner configured as described above, dust and foreign matter may enter the air conditioner through the air outlet 4 when the air conditioner is in the off state, so the inside of the air conditioner must be cleaned. There was a problem that had to be done. Therefore, the blower 4 is opened and closed by moving the shutter means 12 in the vertical direction by one pinion (not shown) and a rack (not shown) that receive the power of the rotation motor (not shown). Thus, the air outlet 4 is closed when the vehicle is stopped, and is lowered during operation and can be stored inside the front panel 14 (see, for example, Patent Document 1).
JP-A-9-166350

  However, according to the conventional air conditioner blowout opening / closing device constructed as described above, the shutter means is moved in the vertical direction by one pinion and rack that are powered by the rotation motor, and the blowout of the blowout opening is performed. Since the structure opens and closes the space, the manufacturing cost increases. Further, the wind direction changing blades 7 are separately provided inside the shutter means, and are composed of a plurality of sheets and have small dimensions in the depth direction. Therefore, the wind direction changing blades 7 are inferior in up and down wind direction changing property that the wind direction does not change as the angle of the wind direction changing blades 7. Had a face.

  The present invention solves the above-mentioned conventional problems, and combines the shutter means and the wind direction changing blades to reliably change the upper and lower wind directions and generate an optimal air flow rich in change while reducing the manufacturing cost. An object of the present invention is to provide a floor-mounted air conditioner that has been made possible.

In order to solve the above-described conventional problems, the floor-mounted air conditioner of the present invention includes an up-and-down air direction change blade at a blowout port and a blade holding member that holds and moves the rotation fulcrum of the up-and-down air direction change blade. During operation, the vertical wind direction changing blade moves to the front of the outlet and rotates to control the vertical wind direction, and when the operation is stopped, the blade holding member operates to be housed in the main body to operate in the vertical direction. It is characterized in that the outlet is closed by the change blade.

  Thus, even if there is no shutter means, it operates so as to store the holding member when operation is stopped, and the air outlet is closed by the up / down air direction changing blade, so that the up / down air direction changing blade can also be used as the shutter means. At the same time, we provide a floor-mounted air conditioner that can reduce the manufacturing cost while generating the optimal airflow that is rich in change by enlarging the vertical direction of the blade in the depth direction of the blades to change the direction of the airflow. can do.

  The floor-mounted air conditioner of the present invention uses the wind direction changing blade also as a shutter means to prevent foreign matter and the like from entering the air conditioner through the air outlet and to change the air direction by changing the upper and lower air directions with certainty. A rich and optimal airflow can be generated and manufacturing costs can be reduced.

  1st invention is equipped with the up-and-down wind direction change blade | wing at the blower outlet, and the blade | wing holding member to hold | maintain and move the rotation fulcrum of the said up-and-down wind direction change blade | wing, and the said up-and-down wind direction change blade | wing is ahead of a blower outlet at the time of driving By moving and rotating, the vertical wind direction is controlled, and when the operation is stopped, the blade holding member operates so as to be housed in the main body, and the blower outlet is closed by the vertical wind direction changing blade. It is a feature. As a result, even if there is no shutter, the holding member can be stored when the operation is stopped, and the air outlet can be closed by the up / down air direction changing blade, and the shutter means and the air direction changing blade can be used together to reliably change the up / down air direction. Thus, it is possible to provide a floor-mounted air conditioner that can reduce the manufacturing cost while generating an optimal air flow rich in change.

  The second invention, in particular, comprises the up-and-down wind direction change blade of the first invention with a curved surface, and controls the wind direction change blade with the concave surface formed by the curved surface facing downward during heating operation, During the cooling operation, by controlling the up / down air direction changing blades with the concave surface facing upward, it is possible to create an air flow downward in the heating operation and upward in the cooling operation.

  In particular, the third invention includes a holding member motor that drives the holding member of the first or second invention, and a blade motor that rotates the up-and-down airflow direction changing blade, and the blade motor is air-conditioned. By being arranged in the machine main body, the blade motor is built in the air conditioner main body, and safety and reliability can be increased.

  In the fourth aspect of the invention, in particular, by arranging a plurality of the vertical wind direction changing blades and the holding members of the vertical wind direction changing blades of any one of the first to third inventions in the vertical direction, the vertical wind direction change is ensured. In addition, even a large outlet in the vertical direction can be closed when stopped.

  In the fifth aspect of the invention, in particular, the position and angle of each of the vertical wind direction changing blades can be arbitrarily determined by operating each of the plurality of vertical wind direction changing blades and the plurality of holding members independently of each other. It is possible to set the airflow more optimally according to the situation.

  The sixth aspect of the present invention, in particular, in any one of the first to fifth aspects of the present invention, when the up / down wind direction changing blades are positioned in front of the outlet during operation, By providing a baffle plate that prevents the dispersion of airflow, it is possible to suppress the airflow that hits the up-and-down airflow direction changing blades from being dispersed to the left and right, and to blow out the airflow reliably in front of the air outlet.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a perspective view of a floor-mounted air conditioner according to a first embodiment of the present invention, in which FIG. 1 (a) shows a state when stopped and FIG. 1 (b) shows a state during operation. FIG. 2 is a side sectional view of the floor-type air conditioner. FIG. 2 (a) shows a state at the time of stop, and FIG. 2 (b) shows a state at the time of operation. The floor-mounted air conditioner is an indoor unit of an air conditioner that is configured to be separated into an indoor unit and an outdoor unit, and among them, the unit is installed on the floor.

  1 and 2, the floor-mounted air conditioner includes an air outlet 4 at the upper front of the cabinet 13, a suction port 5 at the lower front, and an operation unit 1 at the upper part of the suction port 5. Includes a heat exchanger 2, an indoor fan 3, and an indoor fan motor 6. The shape of the blower outlet 4 is not so long and narrow, and the ratio between the vertical dimension and the horizontal dimension is not particularly limited, but the vertical dimension is 1, and the horizontal dimension is about 0.7 to 5.

  During operation of the air conditioner, indoor air is taken in as intake air from the suction port 5 according to a signal from the operation unit 1, and heat is exchanged by the indoor fan motor 6 via the indoor fan 3 that rotates at a predetermined rotational speed. Pass the vessel 2 through. The heat exchanger 2 can cool air as an evaporator during cooling operation, and can heat air as a condenser during heating operation. The cooled or heated intake air is sent to the upper part of the cabinet 13 and blows out into the room from the outlet 4 that collides with the ceiling surface and is opened to the front side.

  At this time, according to the operation instruction from the user who is using the air conditioner, the wind direction is changed to the left and right or up and down. However, in the conventional floor-mounted air conditioner, when stopped (FIG. 6 ( In a)), the shutter 12 built in the center of the front face is lifted in order to completely close the outlet, so that the right / left and up / down wind direction changing blades must be completely accommodated in the outlet 4. The air outlet 4 has a sufficient height in the vertical direction, but is not sufficiently large in the depth direction (for example, in the embodiment of the present invention, the height is about 300 mm and the depth is about 120 mm). It is necessary to incorporate the right and left wind direction change blades and the up and down wind direction change blades in the depth dimension, and each depth dimension must be small, and as described in the problem item, it is difficult to sufficiently control the wind direction. there were.

  3 and 4 are side sectional views in the vicinity of the outlet of the floor-mounted air conditioner according to the first embodiment of the present invention. FIG. 3 shows the state of horizontal or upward blowing during cooling operation. 4 shows the state of the diagonally downward blowing in the heating operation.

  In the first embodiment of the present invention, only the left and right wind direction changing blades 8 are built in the outlet 4, and the upper and lower wind direction changing blades 7 are arranged in two upper and lower stages to be arranged on the upper upper and lower wind direction changing blades 7a and the lower side. The side up / down wind direction changing blade 7b is formed on the front surface so that it can also be used as a shutter. For this purpose, holding members 9 are provided at both ends of the air outlet 4, and the rotation fulcrum 7 c of the up-and-down air direction changing blade 7 is rotatably held and moved at the tip side.

  During the operation of the air conditioner, the holding member 9 (9a, 9b) is extended or moved in the front direction by the holding member motor 10 comprising a stepping motor provided at the outlet 4, and the vertical wind direction changing blade 7 is moved. Let it out. Further, the blade motor 11 for rotating the up / down air direction changing blade, which is a stepping motor arranged on the main body side, is rotated, the driving operation is transmitted by the gear portion built in the holding member 9, and the up / down air direction changing blade 7 is required. Rotate to an angle.

As described above, the wind that has passed through the heat exchanger 2 first passes through the left and right wind direction changing blades 8 and is changed in the left and right directions, and then the wind direction is changed to a predetermined angle in the vertical direction by the up and down wind direction changing blades 7. The Specifically, it is possible to swing between 45 degrees downward and 10 degrees upward. Also, the number of the up / down wind direction changing blades 7 is smaller than that of the conventional blades (1 to 3 compared to the conventional 5 to 6), and the length dimension is increased in the depth direction, that is, the wind flow direction. (For example, about 150 mm in the embodiment of the present invention).

  Thus, the up / down wind direction change blades 7 that are long in the depth direction can increase the air direction changeability of the blown air, and can be reliably blown in a predetermined angle and direction. Moreover, in the conventional structure, since the up-and-down wind direction change blade | wing 7 was arrange | positioned inside the blower outlet 4, when the wind direction was made to face down, it would hit the lower end of the blower outlet 4, and the wind direction could not be changed enough. However, in Embodiment 1 of this invention, since the up-and-down wind direction change blade | wing 7 has protruded ahead from the blower outlet 4, such an obstruction can be avoided and it can fully blow down.

  Next, the operation stop time of the air conditioner will be described. When the operation of the air conditioner is stopped, conventionally, the up / down wind direction changing blade 7 and the left / right wind direction changing blade 8 are both reset to predetermined positions, and the shutter 12 built in the center of the front surface is raised to close the air outlet 4. It was. However, in Embodiment 1 of the present invention, the left and right wind direction changing blades 8 are reset as usual, but the up and down wind direction changing blades 7 operate differently using the holding member 9.

  First, the upper vertical wind direction changing blade 7a is rotated so that the vertical wind direction changing blade 7 is substantially parallel to the front surface of the air conditioner, so that the lower vertical wind direction changing blade 7b does not hit the upper blade. Horizontal. Next, the holding member 9a is moved to the main body side and is operated until it reaches the reset positions arranged on both sides of the air outlet 4. At this time, the holding member motor 10 slides by hitting a stopper (not shown) provided in the air outlet 4 and is stopped at this position. In the stopped state, the upper vertical wind direction changing blade 7a is in a position parallel to the front surface of the main body. Next, the lower vertical wind direction changing blade 7b is similarly rotated so as to be substantially parallel to the front surface, and then the holding member 9b is moved to the main body side and is operated until it hits the stopper in the same manner as the holding member 9a. In this manner, the two up / down air direction changing blades 7 are stopped at a position parallel to the front surface of the main body, and the air outlet 4 is closed by the two up / down air direction changing blades 7. Since the large shutter 12 for blocking that has been necessary in the past is unnecessary, the manufacturing cost can be reduced to the same level or lower as compared with the conventional one.

  In the first embodiment of the present invention, the example using two up / down airflow direction changing blades is described. However, one or three or more blades may be used, and similar operations and effects can be obtained. However, if the number of sheets is too large, the wind direction can be changed, which is different from the conventional one, and the manufacturing cost may be disadvantageous. Of course, when the height of the blower outlet 4 is larger than the width, a large number of sheets are required, and the number is not limited to the number described above.

  In the case of a plurality of vertical wind direction changing blades 7, the length of the holding member 9 may be different or the length of the vertical wind direction changing blades 7 may be different so that each has independent movement and configuration. However, the control of the operation may be performed independently, and the operation may be performed so that the optimum wind direction is obtained according to the driving situation. For example, the length of the upper vertical wind direction change blade 7a is 200 mm, the length of the lower vertical wind direction change blade 7b is 100 mm, the stroke of the holding member 9a (extrusion dimension to the front surface) is 100 mm, and the stroke of the holding member 9b is 50 mm. Thus, the upper vertical wind direction changing blade 7a protrudes ahead of the lower vertical wind direction changing blade 7b, and the wind can be sent further downward. It is also possible to diffuse the wind direction or reduce the flow by changing the angle of the two vertical wind direction changing blades 7.

In the present embodiment, a blade motor 11 for rotating the up-and-down air direction changing blade 7 is built in the outlet 4 side, and the drive operation is transmitted by the gear portion built in the holding member 9 to hold the blade. Although the front end side of the member 9 is configured to be light, the present invention is not limited to this, and a small blade motor is provided as a rotation fulcrum 7c of the vertical wind direction changing blade 7 and the vertical wind direction changing blade 7 is directly arranged. May be rotated. In this way, the gear built in the holding member 9 becomes unnecessary, and the configuration can be simplified.

(Embodiment 2)
3 and 4 are cross-sectional views of the floor-mounted air conditioner according to the second embodiment of the present invention, particularly around the outlet. In FIGS. 1 and 2 of the first embodiment described above, the vertical wind direction changing blade 7 has a flat shape. However, in the second embodiment, a curved surface is provided in the depth direction to improve the wind direction changing characteristics. In order to send the airflow upward during the cooling operation, the blade motor 11 incorporated in the main body is rotated so that the curved upward / downward airflow direction changing blade 7 has a concave surface upward as shown in FIG. The change blade 7 is fixed. In the case of heating operation, the up / down airflow direction changing blade 7 is fixed so that the concave surface faces downward. In a normal case, it is operated so that the concave surface faces downward as in heating. By controlling the up-and-down airflow direction changing blade 7 in this way, it is possible to create an air flow with less resistance in the downward direction during the heating operation and upward in the cooling operation.

  Further, when the operation is stopped with such a configuration, first, the two up-and-down air direction change blades 7 are both turned so that the concave surface is directed downward as in the case of heating, and then is horizontal. Next, only the upper vertical wind direction changing blade 7a is rotated so that the blade is vertical and the concave surface is in the body direction. Then, the holding member 9a is moved and moved toward the main body. The movement stops by hitting the stopper and is fixed at that position. Similarly, the lower up / down wind direction changing blade 7b is also fixed to the stopper of the outlet 4 by the holding member 9b after rotating to the vertical angle.

(Embodiment 3)
FIG. 5 is a side sectional view of the vicinity of the air outlet of the floor-mounted air conditioner according to the third embodiment of the present invention. The rectifying plates 15 are provided on both sides (both sides in the depth direction in the drawing) of the up-and-down wind direction changing blades 7 that protrude forward from the air outlet 4 during operation. The rectifying plate 15 is housed inside the air outlet 4 when the air conditioner is stopped, and approaches the up-and-down airflow direction change blades 7 or in accordance with operating conditions.

  When air is blown out from the outlet 4, the airflow is diffused to some extent when it is blown out. In such a state, if the up-and-down wind direction changing blade 7 protrudes forward as in the present invention, it becomes more diffuse. In particular, as shown in FIG. 5, when trying to increase the wind speed by constricting the concave surfaces of the two upper and lower wind direction changing blades 7 facing each other, if the left and right are not closed, they diffuse to the left and right. Therefore, by providing the rectifying plate 15, such diffusion can be prevented and the wind direction can be controlled efficiently.

  The holding member 9 may be shared by the rectifying plate 15 so that the rectifying plate 15 and the up-and-down air direction changing blades 7 are integrally pushed out.

  As described above, the floor-mounted air conditioner according to the present invention operates so as to store the holding member when the operation is stopped, and closes the air outlet by the up / down air direction changing blades even when the shutter means of the air outlet is not provided. In addition to being able to use the upper and lower airflow direction changing blades as shutter means, the vertical direction of the upper and lower airflow direction changing blades can be increased in size to reliably change the upper and lower airflow direction to generate an optimal air flow that is rich in changes. Therefore, it is needless to say that an air conditioner having a large outlet is not limited to a floor-standing type, and can be applied to a device that blows air, such as a dehumidifier or a dryer.
