JP4977484B2 - Floor-mounted air conditioner - Google Patents

Description

  The present invention relates to an air conditioner in which conditioned air (cold air or warm air) obtained by exchanging heat of inhaled room air is supplied to the room again, and in particular, the longitudinal direction of a vertically long main body. The present invention relates to a floor-mounted air conditioner in which a blower and a heat exchanger are arranged.

  The general configuration of a floor-mounted air conditioner is, for example, a fan mounted at the bottom of a vertically long main body and a heat exchanger disposed at the top so as to be integrated. Compared to the above, there is the flexibility to arbitrarily select the installation position in the room, and there is a feature that the installation work, maintenance, and cleaning are easy.

  A sirocco fan is usually adopted as a blower of such a floor-type air conditioner. However, when dust or the like adheres to the blade (blade) of the sirocco fan, noise is generated and the blowing capacity is lowered. Therefore, since the blade must be periodically cleaned, the front panel covering the front surface of the main body is made detachable (for example, Patent Document 1).

  The floor-mounted air conditioner disclosed in Patent Document 1 employs a method of sucking indoor air from the back of the main body. In this case, the air filter is slid laterally on the back of the main body to be attached and detached. I am doing so. Therefore, it is necessary to secure the space necessary for attaching and detaching the air filter next to the main body, so this part becomes a dead space where other furniture etc. can not be placed, and it is installed between indoor walls and furniture The built-in method cannot be used. Moreover, since the indoor air intake port approaches the indoor wall, there has been a problem that the wall surface becomes dirty.

  As a method for preventing such a problem from occurring, there is a method in which an indoor air inlet is formed on the front surface of the main body (for example, Patent Document 2). In the configuration disclosed in Patent Document 2, indoor air is sucked from the suction port of a suction grill provided at the lower part of the main body and heat exchange is performed. Therefore, since the intake of indoor air and the discharge of conditioned air are all performed in front of the main body, the installation position is not limited without considering the lateral space of the main body.

However, in the conventional floor-mounted air conditioner having the above configuration, since the conditioned air discharge port faces the front, the conditioned air is discharged only in one direction forward, and the flow in the lateral direction is poor. A uniform temperature distribution cannot be obtained in the room. Therefore, in order to make the temperature distribution in the room uniform, a conditioned air discharge port is formed on both sides of the upper part of the main body (for example, Patent Document 3).

  In the configuration disclosed in Patent Document 3, blowout portions are formed on both sides of the upper portion of one front panel that covers all of the opening portions of the main body, and a suction portion is simply opened at the lower portion. In such a configuration, in order to most effectively prevent dust from entering the main body, an air filter is detachably disposed on the back surface of the suction portion.

  As described above, the floor-mounted air conditioner has an advantage that maintenance and cleaning can be easily performed because it is approximately the same height as the human body. However, in the configuration in which the blowout part and the suction part are formed at the same time on the front panel, even when the air filter disposed in the suction part is attached to the lower part of the main body and removed for cleaning, a plurality of fixing tools such as screws are removed to The panel must be separated from the body.

  However, this work is quite large, and there is a risk that the front panel, which is a heavy object, will fall over and the decorative surface may be damaged, or the electrical components incorporated in the front panel may be damaged. Also, when cleaning the sirocco fan, disconnect the motor from the front panel, the motor for driving the flap, the power supply to the display device, etc., and the lead wire to send and receive signals. Must be completely separated from the body. However, when the lead wire is connected by the connector, it is easy to release the connection, but when attaching the front panel, it is extremely difficult to reconnect the connector while supporting the front panel. It is a problem that needs to be solved from the viewpoint of safety.

Therefore, the present invention solves the above problems by means described below. That is, according to the first aspect of the present invention, a blower and a heat exchanger are arranged in the longitudinal direction of a vertically long main body, and the indoor air sucked by the blower is heat-exchanged by passing through the heat exchanger. The front surface of the main body , which is generated in the air and is supplied to the room, is attached to the upper half of the upper front surface where the air outlet for the conditioned air is formed, and is formed with a suction port for sucking room air A floor-mounted air conditioner in which one side surface of a lower front panel attached to the lower half side of the lower front panel is pivotally supported to the main body so that the lower front panel can be opened on one side. A suction port for sucking room air is formed in the vertical direction on both sides of the air bag, a detachable air filter is attached to the suction port, and a vertical flap is provided to cover the opening of the suction port from the front side. Book Synchronization with opening and closing the operating states.

According to a second aspect of the present invention, in the floor-mounted air conditioner of the first aspect, the vertical flap is pivotally supported at the front end side, and swings when driven by a motor so as to expand toward the rear of the main body. To be possible.

  According to the first invention, since one side end of the lower front panel covering the lower half of the main body of the floor-mounted air conditioner is pivotally supported to the main body, the lower front panel is opened and closed by one opening. can do. Thereby, since the front surface of the lower part of the main body is greatly opened, work efficiency such as attachment / detachment of the air filter attached to the lower front panel and cleaning of the blower can be improved. In addition, even during such work, the lower front panel is in a state where the side edges are held by the main body, so that it is possible to eliminate the possibility of damage due to falling. Further, since the lower front panel is not separated from the main body, the electrical components of the lower front panel and the main body can be directly connected by lead wires.

  According to the second invention, in addition to the effect of the first invention, a vertical flap that covers the opening of the suction port from the front surface is provided. Therefore, when the operation is stopped, the opening is closed by the vertical flap. The air filter attached to the mouth is shielded from the field of view, and the aesthetic appearance can be improved.

  According to the third invention, in addition to the effect of the second invention, the indoor air is sucked from the rear of the main body, so that the generation of so-called shortcut airflow in which the conditioned air supplied into the room is directly sucked is prevented. Thus, the heat exchange efficiency can be prevented from decreasing.

  Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an appearance of a floor-mounted air conditioner 1 according to the present invention, and FIG. 2 shows a front view and FIG. 3 shows a side view. In the case of the present embodiment, the upper part of the vertically long main body 2 is a heat exchange part, and the lower part is an indoor air suction part. While the floor-mounted air conditioner 1 is installed indoors, a refrigerant circuit is configured with the outdoor unit 40 installed outdoors, and an electric circuit that performs power feeding and signal transmission / reception is connected.

  4 and 5 show the internal structure of the floor-mounted air conditioner 1, in which the heat exchanger 3 is disposed in an inclined state at the upper part of the main body 2, and the blower 4 disposed at the lower part. The indoor air sent from the room is heat-exchanged to generate conditioned air. Also, an electrical box 5 that controls the overall electrical control is disposed at the middle portion of the main body, and an air supply / exhaust device 6 is disposed at the bottom.

  The main body 2 is assembled in a vertically long bowl shape with a steel plate or the like, and has a front surface and a bottom surface opened. A base leg 2A is attached to the bottom surface opening, and an intermediate portion is reinforced by a partition plate 2B. As shown in FIG. 6, the blower 4 includes a sirocco fan 4a, a motor 4b that rotationally drives the sirocco fan 4a, and a fan case 4c that houses the sirocco fan 4a. The fan case 4c includes a suction port 4c-1 that sucks room air when the sirocco fan 4a rotates and a discharge port 4c-2 that discharges the sucked room air toward the upper heat exchanger 3.

  Since it is configured in this way, the indoor air blown from the blower 4 flows in the main body 2 as shown by an arrow as shown in FIG. 5, and heat exchange (heating or heating) passes through the heat exchanger 3. Cooled) and conditioned air is supplied into the room through the outlets 10a and 10b of the upper front panel 10. The upper front panel 10 is fixed to and integrated with the opening of the upper body 2 from the partition plate 2B, and the wind direction is adjusted at the outlet 10a formed in an inclined state toward both sides. A mechanism is provided.

  As shown in FIG. 4, an example of the configuration of the wind direction adjusting mechanism includes a plurality of horizontal flaps 11 having the same shape and a plate shape that are axially supported and arranged at predetermined intervals in the outlet 10 a portion. The horizontal flaps 11 in the same row are configured to swing in synchronization in the same direction. An output shaft of a stepping motor 13 having a built-in speed reduction mechanism is connected to the uppermost horizontal flap 11, and each horizontal flap swings as the stepping motor 13 is driven. An angle is changed and the angle of the up-down direction which conditioned air blows off with this can be changed arbitrarily.

  The outlet 10a is provided with a vertical flap 14 so that the horizontal width of the conditioned air can be adjusted. The upper end of the vertical flap 14 is pivotally supported by the upper front panel 10 and the lower end is connected to the output shaft of a stepping motor 15 incorporating a speed reduction mechanism. Therefore, by driving the stepping motor 15, the vertical flap 14 swings and expands toward the front of the main body 2, and the horizontal width of the conditioned air blown out can be arbitrarily changed. With such a configuration, the horizontal direction of the conditioned air to be blown out can be arbitrarily set by the button operation of the remote controller R or the operation box 18 of the main body 2, or the swing control can be periodically reciprocated within a predetermined range. It becomes possible.

  In addition, in this embodiment, the blower outlet 10b is formed also in the top part of the upper front panel 10, and the horizontal flap 16 of the shape corresponding to this blower outlet 10b is provided. Since both ends of the horizontal flap 16 are pivotally supported by the upper front panel 10, the tip of the horizontal flap 16 swings up and down by the power transmitted from the output shaft of the stepping motor 17 incorporating the speed reduction mechanism via the link mechanism 17a. . Therefore, by opening the outlet 10b with the horizontal flap 16, the conditioned air can be guided toward the ceiling of the room, so that the temperature deviation of the room air during the cooling / heating operation can be prevented. With such a configuration, it is possible to set so that the air outlet 10b is automatically opened when the cooling operation or the air blowing operation is instructed.

  At the lower end of the upper front panel 10, an operation box 18 having a manual switch push button and an indicator is arranged on the front surface, and a drive signal is sent from the operation box 18 to the stepping motors 13, 15, and 17. Wiring is made. Further, the operation box 18 and the electrical equipment box 5 are connected by a lead wire W1, and power feeding and signal transmission / reception are performed.

  Next, the configuration of the lower front panel 20 will be described. On both sides of the lower front panel 20 covering the lower opening surface of the main body 2, suction ports 21 into which room air sucked by the blower 4 flows are formed in an inclined state toward the outside. As shown in FIG. 7, an air filter 22 is detachably disposed on the back surface side of the suction port 21, and a vertical flap 23 is disposed on the front surface side. The vertical flap 23 has a lower end on the front end side pivotally supported by the lower front panel, and an upper end connected to the output shaft of the stepping motor 24 having a built-in speed reduction mechanism. Accordingly, when the operation is started, the vertical flap 23 is swung by the driving of the stepping motor 24 and spreads toward the rear of the main body 2 to suck in indoor air. When the operation is stopped, the vertical flap 23 closes the suction port 21. It becomes possible.

  The stepping motor 24 for driving the vertical flap 23 must be disposed in both side ends of the upper frame of the lower front panel 20. Accordingly, the upper frame portion has a hollow structure, and the stepping motor 24 is disposed therein, and a lead wire W2 connected to the stepping motor 24 is wired.

  Hinge arms 25 and 26 to which hinge bases 25a and 26a are fixed are provided on the upper and lower ends of the side portion that is the suspending side of the lower front panel 20. On the other hand, an angle member 27 as shown in FIG. 8 is fixed to the main body 2, and a fixing screw 28 inserted through the through holes 25 b and 26 b at the tips of the hinge arms 25 and 26 is screwed to the angle member 27. As a result, the lower front panel 20 is in a single-open state, and the state supported by the main body 2 is maintained even in the state shown in FIG.

  Therefore, a complicated operation of completely removing the lower front panel 20 from the main body 2 can be omitted, and the sirocco fan 4a of the blower 4 can be cleaned or the air filter 22 can be attached and detached. However, when the stepping motor 24 for driving the vertical flap 23 is built in the lower front panel 20 as in the floor-mounted air conditioner 1 of the present invention, the lower front panel is also used in order not to cut the wiring connection with the main body 2. It is desirable that the panel 20 be in a single-open state without being completely removed from the main body 2.

  In addition, a small handle 20a is provided on the side frame on the expansion side of the lower front panel 20 so that opening and closing is easy, and a magnet catcher 29 is provided on the main body to ensure the closed state of the lower front panel 20. I am doing so. When the floor-mounted air conditioner 1 of the present invention configured as described above is not in operation, the vertical flap 14 closes the outlet 10a of the upper front panel 10 and the vertical flap 23 as shown in FIGS. Closes the inlet 21 of the lower front panel 20, and the horizontal flap 16 closes the outlet 10 b at the top of the upper front panel 10.

  When the operation of the floor-type air conditioner 1 of the present invention is stopped from the above state by the remote control operation or the like, the vertical flap 14 of the upper front panel 10 is moved to the front end as shown in FIG. Expands and conditioned air is blown forward. On the other hand, the rear end of the vertical flap 23 of the lower front panel 20 is widened, and the room air is sucked from the rear of the main body 2.

  Therefore, the conditioned air is effectively supplied into the room from the outlet 10a of the upper front panel 10, but when the intake port 21 of the lower front panel 20 is not provided with a vertical flap as shown in FIG. In this way, part of the conditioned air is sucked into the suction port 21 and a so-called shortcut airflow is formed, which causes a decrease in heat exchange efficiency. Further, since the vertical flap 14 is provided in the suction port 21 of the lower front panel 20, the cotton dust trapped and deposited on the air filter 22 by the vertical flap 14 is covered and the aesthetic appearance can be maintained.

  As described above, according to the floor-mounted air conditioner 1 of the present invention, the upper front panel 10 is fixed to the main body 2 while the lower front panel 20 is in a single-open state. There are effects peculiar to the present invention, such as easy replacement of the air filter.
