Embodiment 1 FIG.
FIG. 1 is an exploded perspective view of the whole indoor unit of an air conditioner according to Embodiment 1 of the present invention. FIG. 2 is a cross-sectional view of the entire indoor unit of the air conditioner according to Embodiment 1 of the present invention. FIG. 3 is a perspective view of a state in which the right vertical wind direction plate is removed from the drain pan of FIG. 1.

  As shown in FIGS. 1 and 2, an indoor unit (hereinafter referred to as “indoor unit”) 100 of an air conditioner has a suction port 1 a and a blow-out port 1 b formed therein, and a housing 1 that is a design component, And a base 2 installed on a wall surface (not shown). The housing 1 and the base 2 constitute an indoor unit main body 100a, and an air passage extending from the inlet 1a to the outlet 1b is formed inside the indoor unit main body 100a.

  The indoor unit 100 is further disposed in the indoor unit main body 100a. The blower fan 3 sucks room air from the suction port 1a and blows conditioned air from the blower port 1b, and the air passage 1c extends from the blower fan 3 to the blower port 1b. And a heat exchanger 4 for generating conditioned air by exchanging heat between the indoor air and the refrigerant. A drain pan 5 that receives drain water dripping from the heat exchanger 4 is disposed below the heat exchanger 4. In the drain pan 5, the upper surface 5 a forms a drain pan surface that actually receives drain water, and the lower surface (corresponding to an “air path forming member”) 5 b forms a part of the air path 1 c. The indoor unit main body 100a further includes an automatic filter cleaning mechanism 6 and an electrical product 7.

  In addition, the blower outlet 1b of the housing 1 opens and closes the blower outlet 1b, and adjusts the blowout direction of the conditioned air generated by the heat exchanger 4 in the vertical direction. 8) (hereinafter may be collectively referred to as the up-and-down wind direction plate 8).

  The up-and-down wind direction plate 8 is a plate-like member whose longitudinal direction is the left-right direction. The lower vertical wind direction plates 8c and 8d are formed to have a longer length in the short direction than the upper vertical wind direction plates 8a and 8b from the viewpoint of ease of wind direction control.

  The vertical wind direction plate 8 is detachably provided on the drain pan 5 to enable internal cleaning of the indoor unit main body 100a. Specifically, support portions (not shown) are provided at both ends in the longitudinal direction of the vertical wind direction plate 8, and support shafts (not shown) protruding sideways are provided on the support portions. One of the support shafts (not shown) is rotatably supported by bearings (not shown) on the left and right side surfaces of the drain pan 5 at both ends in the longitudinal direction of the outlet 1b. The other support shaft is the central portion in the longitudinal direction of the outlet 1b, and the bearing portions 52a and 52b (see FIG. 6 described later) of the support portions 51a and 51b (see FIG. 6 described later) provided on the lower surface 5b of the drain pan 5. Reference) is supported rotatably. Of the two support shafts of the vertical wind direction plate 8, the support shafts on the left and right side surfaces of the drain pan 5 are connected to a motor (not shown), and the vertical wind direction plate 8 is rotatable in the vertical direction.

  A stop switch (not shown) for stopping the blower fan 3 is built in the bearing portion 52a that supports the support shafts of the upper vertical wind direction plates 8a and 8b, and the upper vertical wind direction plates 8a and 8b are connected to the drain pan 5. When the fan is removed, the blower fan 3 is stopped. The stop switch is provided only in the upper bearing portion 52a, and is not provided in the lower bearing portion 52b. Therefore, if the upper vertical wind direction plates 8 a and 8 b are removed from the drain pan 5 during the operation of the blower fan 3, the blower fan 3 stops, but the lower vertical wind direction plates 8 b and 8 c are removed from the drain pan 5. The blower fan 3 is operated without stopping.

  In addition, although the structure provided with the up-and-down wind direction board 8 divided into right and left is shown here, the structure integrated in the longitudinal direction may be sufficient instead of dividing into right and left. Moreover, although the structure in which the up-and-down wind direction board 8 was provided in the drain pan 5 was shown, it should just be provided in the air path formation member in short.

  The blower outlet 1b of the housing 1 is further provided with two left and right airflow direction adjusting mechanisms 10 arranged upstream of the vertical airflow direction plate 8 for adjusting the right and left airflow direction of the conditioned air in the left and right direction of the blower outlet 1b. Is arranged. The left and right wind direction adjusting mechanism 10 is not limited to two configurations on the left and right sides, and may be an integral configuration without being divided into left and right like the vertical wind direction plate 8.

Next, the left / right wind direction adjusting mechanism 10 will be described.
FIG. 4 is a perspective view of the left / right airflow direction adjusting mechanism of FIG. FIG. 5 is a perspective view of the support member of FIG. 4, in which (a) the front surface side and (b) the back surface side are collectively shown. 4 shows the right and left air direction adjusting mechanism 10 on the right side, and FIG. 5 shows a support member of the left and right air direction adjusting mechanism on the left side. FIG. 6 is a perspective view showing a state in which all the vertical wind direction plates are removed from the drain pan of FIG. 1 and the horizontal wind direction adjusting mechanism is pulled out from the mounting position.

  The left and right airflow direction adjusting mechanism 10 includes a plurality of left and right airflow direction plates 11, a support member 12, a connecting rod 13 that forms an interlocking mechanism that interlocks the left and right airflow direction plates 11, a motor 14 that moves the connecting rod 13 in the left-right direction, It has the connection body 15 which connects the connecting rod 13 and a drive means.

  The plurality of left and right wind direction plates 11 are arranged at intervals in the left-right direction, and are supported by the support member 12 so as to be rotatable in the left-right direction. Each of the left and right wind direction plates 11 has a connecting projection for connecting with the connecting rod 13, and the connecting projection is inserted into an insertion hole (not shown) provided in the connecting rod 13. Thus, the plurality of left and right wind direction plates 11 are connected to the connecting rod 13. One end of the connecting rod 13 is connected to the motor 14 via the connecting body 15, and the rotational drive of the motor 14 is transmitted to the plurality of right and left wind direction plates 11 via the connecting body 15 and the connecting rod 13. The left and right wind direction plates 11 are rotated in the left-right direction in conjunction with each other.

  The left and right airflow direction adjusting mechanism 10 can be moved from the mounting position in order to enable internal cleaning, and can open the outlet 1b. Specifically, as shown in FIG. 6, the left / right airflow direction adjusting mechanism 10 can turn around one end of the left / right airflow direction adjusting mechanism 10 and pull the other end side out of the indoor unit body 100a. ing. At the end of the support member 12 of the left / right airflow direction adjusting mechanism 10 opposite to the rotation fulcrum, a knob 16 is provided integrally with the support member 12 when the left / right airflow direction adjusting mechanism 10 is pulled out of the indoor unit main body 100a. It has been.

  Here, as shown in FIG. 6, when the lower vertical wind direction plates 8c and 8d are removed and the left and right wind direction adjusting mechanism 10 is moved from the mounting position, the air path communicating with the blower fan 3 from the outlet 1b. 1c can be accessed from the user side. Therefore, a finger or a foreign object or the like is inserted from the outlet 1b and comes into contact with the blower fan 3, so that the blower fan 3 may be damaged. In addition, when the upper vertical wind direction plates 8a and 8b are removed, the blower fan 3 stops as described above, and thus the above inconvenience does not occur. Based on these, if the lower vertical wind direction plate 8 is removed and the upper vertical wind direction plates 8a and 8b are attached, the right and left wind direction adjustment mechanism 10 may be removed, which may cause inconvenience. Become.

  Therefore, in the first embodiment, in order to avoid such inconvenience, a structure in which the left / right airflow direction adjusting mechanism 10 cannot be removed with the up / down airflow direction plate 8 attached thereto is adopted. Specifically, when the vertical wind direction plates 8a and 8b are arranged at the outlet 1b, when the left and right wind direction adjusting mechanism 10 is moved from the mounting position to open the outlet 1b, the left and right wind direction adjusting mechanism 10 is set. The indoor unit 100 is provided with stopper means 17 for restricting the movement of the indoor unit 100. Hereinafter, the configuration of the stopper means 17 will be described.

  FIG. 7 shows a cross-section of the drain pan in the installation position of the drain pan in the housing of FIG. 1, (a) a state where both the upper and lower vertical wind direction plates are mounted, and (b) a lower vertical wind direction plate is It is the figure which showed collectively the state removed and the right-and-left wind direction adjustment mechanism being pulled out below slightly. FIG. 8 is a perspective view of the drain pan as seen from below with the up-and-down wind direction plate of FIG. 1 opened. FIG. 9 is a view of FIG. 8 viewed from directly below. FIG. 10 is an enlarged perspective view of the storage recess of the stopper piece of FIG.

  The stopper means 17 includes a stopper piece 17 extending outward from the support member 12, and the stopper piece 17 is at least partly a vertical wind direction plate with the left and right wind direction adjusting mechanism 10 mounted at the mounting position. No. 8 indoor unit main body 100a is located on the back side. The stopper piece 17 has an extension length so that the upper and lower wind direction plates 8 come into contact with the upper and lower wind direction plates 8 when the left and right wind direction adjusting mechanism 10 is pulled out regardless of the position of the movable range. Has been.

  The position of the stopper piece 17 on the support member 12 is not limited, but here, as shown in FIG. 6, the stopper piece 17 is on the end side opposite to the rotation fulcrum of the left / right wind direction adjusting mechanism 10. If the stopper piece 17 is provided at a position close to the rotation fulcrum, the support member 12 is bent and deformed with the stopper piece 17 as a fulcrum when the knob portion 16 is gripped and the left and right wind direction adjusting mechanism 10 is pulled out strongly. there is a possibility. Therefore, by providing the stopper piece 17 at the end opposite to the rotation fulcrum, it is possible to prevent such a bending of the support member 12 and to stably exhibit the function as the stopper means. For the above reasons, the position of the stopper piece 17 is preferably the end on the opposite side of the rotation fulcrum, but is not limited to this position, and when the left and right wind direction adjusting mechanism 10 is rotated and pulled out, Any position that abuts against the vertical wind direction plate 8 may be used.

  Further, the end side of the support member 12 opposite to the rotation fulcrum is the portion where the movement becomes the largest in the operation of grasping the knob portion 16 and pulling out the left and right wind direction adjusting mechanism 10, and is easily subjected to a drawing force. Part. Therefore, the stopper piece 17 is formed integrally with the knob portion 16, and a rib 17a (see FIG. 5B) is provided on the back surface, so that the rigidity of the stopper piece 17 is enhanced. These configurations for increasing the rigidity are not necessarily essential, and may be omitted if there is no problem with the rigidity.

  Further, the stopper piece 17 is housed in a housing recess 53 (see FIGS. 6 to 10) of the stopper piece 17 provided on the lower surface 5 b of the drain pan 5 in a state where the left / right airflow direction adjusting mechanism 10 is mounted on the drain pan 5. The Thus, the conditioned air passing through the air passage 1 c is not blocked by the stopper piece 17.

  Moreover, the stopper piece 17 is configured in a tapered shape. If the tip of the stopper piece 17 is heavy, the tip of the stopper piece 17 may be hung downwardly away from the storage recess 53, and may block the air passage 1c. Therefore, in order to reduce the weight of the tip of the stopper piece 17 and prevent the air passage 1c from being obstructed, the tip of the stopper piece 17 is tapered. The storage recess 53 for storing the stopper piece 17 only needs to have a depth that allows the stopper piece 17 to be stored. However, the depth is set so that the tip of the stopper piece 17 that is likely to hang down is always stored. It should be decided. In addition, as long as there is no worry that the tip of the stopper piece 17 hangs down, it does not need to be tapered, and the shape is arbitrary.

  Next, the operation of the first embodiment configured as described above will be described. During the cooling or heating operation, the blower fan 3 rotates, so that indoor air is sucked into the indoor unit main body 100a from the suction port 1a. The sucked air is cooled or heated by exchanging heat with the refrigerant in the heat exchanger 4, and the cooled or heated air-conditioned air is adjusted in wind direction by the up-and-down air direction plate 8 and the left and right air direction adjusting mechanism 10, and the outlet 1b. Is blown into the room. Further, during cooling operation, drain water condensed in the heat exchanger 4 is accumulated in the drain pan 5 and discharged outside the room.

  Thus, when the upper vertical wind direction plates 8a and 8b are removed during the operation of the blower fan 3, the stop switch is turned on and the blower fan 3 is stopped. On the other hand, when the left / right wind direction adjusting mechanism 10 is to be pulled out of the indoor unit main body 100a with the up / down wind direction plates 8a, 8b attached, the stopper piece 17 comes into contact with the back surface of the up / down wind direction plates 8a, 8b to adjust the left / right wind direction. The drawer of the mechanism 10 is restricted. Therefore, the air passage 1c communicating with the blower fan 3 from the outlet 1b during the operation of the blower fan 3 is not opened so as to be accessible by the user. For this reason, it becomes possible to prevent insertion of a finger or a foreign object into the air passage 1c.

  The stopper piece 17 adjusts the left / right wind direction regardless of the movable position of the up / down wind direction plates 8a, 8b and the width of the up / down wind direction plates 8a, 8b in the short direction. It is comprised so that drawer | drawing-out of the mechanism 10 can be controlled. Therefore, if the way of viewing is changed, the degree of freedom in the width in the short direction of the up and down wind direction plates 8a and 8b is obtained.

  In addition, when moving the left and right airflow direction adjusting mechanism 10 to open the air outlet 1b, here, an example of a configuration in which the left and right airflow direction adjusting mechanism 10 is rotated around one end and pulled out to the outside of the indoor unit main body 100a has been described. However, it is not limited to this. In short, it is only necessary that the left / right airflow direction adjusting mechanism 10 is configured to be movable from the mounting position so that internal cleaning can be performed. For example, it may be configured as shown in FIG.

FIG. 11 is a diagram showing another example of movement of the left / right airflow direction adjusting mechanism in the indoor unit of the air conditioner according to Embodiment 1 of the present invention.
In the example shown in FIG. 11, the left and right airflow direction adjusting mechanism 10 is detachably attached to the attachment position, and the blowout port 1b is opened so that the inside can be cleaned by completely removing the left and right airflow direction adjustment mechanism 10 from the attachment position. is there. Specifically, both end portions of the support member 12 are formed as flat insertion portions 12a, and the support member 12 of the left and right airflow direction adjusting mechanism 10 is slid downward along the lower surface 5b of the drain pan 5, thereby making the insertion portion 12a In this structure, the drain pan 5 is inserted into and engaged with an engaging portion 54 provided on the lower surface 5 b of the drain pan 5.

  In the case of this structure, when removing the left / right airflow direction adjusting mechanism 10, the support member 12 is slid upward along the lower surface 5 b of the drain pan 5 to release the engagement between the insertion portion 12 a and the engagement portion 54. Thus, the left / right wind direction adjusting mechanism 10 is removed from the drain pan 5. In this structure, the stopper piece 17 can be made to function by setting it as the following structures. In other words, when the upper vertical wind direction plates 8a and 8b are mounted, the slide unit can only be slid within a range in which the engagement between the insertion portion 12a and the engagement portion 54 is not released. As a result, the insertion portion 12a remains locked to the locking portion 54, and at least a part of the stopper piece 17 is positioned on the back side of the vertical wind direction plate 8, so that the right and left wind direction adjusting mechanism 10 cannot be removed. . Thus, even in the configuration in which the left / right wind direction adjusting mechanism 10 is detachably mounted at the mounting position, the stopper piece 17 functions in a state where the up / down wind direction plate 8 is disposed at the outlet 1b.

  Moreover, you may make it dent part of the lower surface 5b of the drain pan 5, and to accommodate the latching | locking part 54 in the recessed part with the insertion part 12a so that an air path may not be obstruct | occluded by the latching | locking part 54. FIG.
