Detailed Description
(first embodiment)
Hereinafter, a first embodiment of the present invention will be described in detail with reference to fig. 1 to 11. In the present embodiment, as shown in the external view of fig. 3, an air conditioner 1 as an indoor unit of a separate wall-mounted air conditioner including an indoor unit and an outdoor unit will be described as an example. However, in the air conditioner according to the embodiment of the present invention, the outlet B of the air flow of the conditioned air has an elongated shape extending in the predetermined direction, and a plurality of wind direction plates that adjust the wind direction in the positive direction and the negative direction of the predetermined direction may include wind direction adjusting means that are arranged on the support plate along the predetermined direction. Therefore, the air conditioner may be a ceiling-mounted type or a floor type, or may be an indoor exclusive type (wall-mounted type air conditioner) without an outdoor unit.
Although the drawings show various components of the air conditioner 1, descriptions of components not related to the embodiment are omitted. Those components whose description is omitted are also understood to be the same as those of known components. The purpose of the drawings is to briefly explain the configurations such as the shapes, structures, positional relationships, and the like of the respective members, and the air conditioner according to the embodiment of the present invention is not limited to the configurations shown in the drawings. These aspects are also the same as the other embodiments.
(overview of air conditioner 1)
First, a schematic configuration of the air conditioner 1 according to the present embodiment will be described with reference to fig. 1 to 5.
Fig. 3 is a perspective view showing an external appearance of the air conditioner 1, and shows a state in which the air outlet B of the airflow is closed. Fig. 4 is a perspective view showing an external appearance of the air conditioner 1, and shows a state in which the air conditioning operation is performed, the airflow panel 140 is opened, and the outlet B of the airflow is recognizable from the outside. The air conditioner 1 includes a front side casing 20, a rear side casing 30, and an air outlet module 10, and these constitute a casing of the air conditioner 1. Fig. 5 is an exploded view showing the air conditioner 1 divided into the front side casing 20, the rear side casing 30, and the air outlet module 10. Fig. 5 also shows a cross flow fan 40 installed inside the air conditioner 1.
The rear side housing 30 is fixed to a wall surface of a room to be air-conditioned. The air conditioner 1 has a rectangular box shape as a whole, and has an elongated air outlet B provided in a longitudinal direction thereof. As shown in the drawings, the longitudinal direction of the air outlet is the X direction, and the Y direction and the Z direction are defined so that the XZ plane is parallel to the wall surface on which the rear side casing 30 is mounted. The direction of the Y axis is a direction from the wall surface on which the air conditioner 1 is mounted toward the front. When the air conditioner 1 is installed on a wall parallel to a vertical surface in such a manner that the X axis becomes horizontal, the Z axis direction becomes the upward direction of the vertical direction. In the present invention, the longitudinal direction (parallel to the X axis) of the air outlet B is referred to as the lateral direction or the left-right direction, the X axis is oriented to the left, and the direction opposite to the X axis is oriented to the right. When the user faces the air outlet B (the front of the air conditioner 1), the directions correspond to the left and right directions, respectively, as viewed from the user. The direction of the Y axis is referred to as the near direction, and the direction opposite to the Y axis is referred to as the far direction. This is because the user looks toward the air outlet B (the front side of the air conditioner 1) and the user looks like the front and rear directions. Therefore, the air flow direction of the air outlet B is roughly the Y-axis direction (the near direction).
Further, in the present invention, for convenience of understanding, a direction parallel to the Z axis may be referred to as an up-down direction, a direction of the Z axis may be referred to as an upward direction, and a direction opposite to the direction of the Z axis may be referred to as a downward direction. This is a case where the air conditioner 1 is mounted on a wall parallel to a vertical plane in such a manner that the X axis becomes horizontal, and for ease of understanding of the description, the mounting method of the air conditioner is not limited thereto.
As shown in fig. 3 and the like, an air inlet I formed by a plurality of beams and gaps therebetween is provided above (in the positive Z-axis direction) the front side casing 20 and the rear side casing 30. As shown in fig. 5, the cross flow fan 40 is a fan having a cylindrical shape with a horizontal axis (a rotation axis is parallel to the X axis) and generating an air flow, and includes a plurality of blades for sucking and transporting air in a circumferential direction. Although not shown, a heat exchanger is provided so as to surround the upper periphery of the cross flow fan 40. The cross-flow fan 40 rotates to draw air into the air conditioner 1 from the inlet I, and creates an airflow that blows the drawn air into the room from the outlet B through the heat exchanger.
As shown in fig. 5, the air outlet module 10 is provided below the front side casing 20 (Z-axis negative direction). The air outlet module 10 is configured by assembling an airflow direction adjusting unit 120 including a plurality of vertical air discharge windows 122 (wind direction plates), an airflow panel 140, and the like to a housing 100 constituting the air outlet B. The specific structure regarding the blow-out port module 10 is described later. The direction of the airflow blown out into the room is determined by the airflow panel 140 and the vertical exhaust window 122 of the airflow direction adjustment unit 120.
The airflow panel 140 is controlled to open and close by a control device (not shown) in the air conditioner 1 according to the operating state of the air conditioner 1. As shown in fig. 3, in the case where the airflow panel 140 is closed, the air outlet B of the airflow is blocked,
the airflow panel 140 functions as an exterior panel of the air conditioner 1. When the airflow panel 140 is opened by rotating in the circumferential direction of the X axis, as shown in fig. 4, the outlet B, which is a flow path of the airflow, is exposed. The airflow panel 140 adjusts the orientation of the airflow blown out from the air outlet B into the room in the vertical direction (parallel to the Z axis) according to the rotation angle.
Fig. 2 is a perspective view showing an external appearance of the air conditioner 1, and shows a state where the airflow panel 140 is detached from the air conditioner 1.
The airflow panel 140 is a substantially plate-shaped member having a horizontal length, and has a short shaft 141 as a rotation shaft at one end thereof and an engagement hole 142 at the other end thereof. Since the stub shaft 141 can be pushed inward and detached from the shaft hole 101 provided in the housing 100 of the air outlet module 10, the user can detach the airflow panel 140 from the main body of the air conditioner 1. The engagement hole 142 is engaged with an engagement shaft 151 of an airflow panel rotation unit 150 attached to the main body side (the casing 100 side) of the air conditioner 1.
The airflow panel 140 obtains a driving force in a rotation direction from the engagement shaft 151 of the airflow panel rotation unit 150, and performs adjustment of a rotation angle for adjusting the orientation of the airflow in the vertical direction (parallel to the Z axis). The airflow panel 140 is a substantially plate-shaped member, and has a relatively simple structure with substantially no movable portion therein, so that it is light in weight and can be easily attached and detached, cleaned, and washed by a user.
In the air outlet B, a plurality of vertical exhaust windows 122 whose orientation in the left-right direction can be changed are provided on the rear side of the airflow panel 140, and can be easily recognized from the outside in a state where the airflow panel 140 is detached. Further, in the outlet B, an ion generating unit 110 is disposed at an upper portion near the central portion.
Fig. 1 is a perspective view showing an external appearance of the air conditioner 1, and shows a state in which the airflow direction adjusting unit 120 further including a plurality of vertical exhaust louvers 122 is removed from the state of fig. 2. As is apparent from fig. 1 and 2, the air conditioner 1 further includes two airflow direction adjusting units 120 arranged in parallel on the left and right sides in the air outlet B. The airflow direction adjustment panel 120 adjusts the vertical direction of the airflow blown out from the air outlet B into the room, in accordance with the direction of the vertical exhaust windows 122. In the interior of the air outlet B, the upper guide post 106 is formed in the vertical direction on the back side of the position where the airflow direction adjustment unit 120 is attached.
(outline of the air-direction adjusting unit 120 and the outlet module 10)
Next, the configuration of the air outlet module 10 including the configuration of the air outlet module 10 and the housing 100 in which the air direction adjusting means 120 and the like are arranged will be described with reference to fig. 6 to 9.
Fig. 6 is a perspective view showing the air outlet module 10, and shows the air outlet module 10 in an exploded manner. The outlet module 10 includes a housing 100, an ion generating unit 110, two airflow direction adjusting units 120, a driving unit 130, an airflow panel 140, and an airflow panel rotating unit 150. Fig. 7 is an enlarged perspective view of the ion generating unit 110, the driving unit 130, and the left wind direction adjusting unit 120 mounted on the housing 100. The ion generating unit 110 is an integral unit having openings for blowing out ions on the left and right sides, respectively. Each air direction adjustment unit 120 is detachably fitted to the installation portion 102 at the bottom (surface on the negative Z-axis direction side) of the outlet port B in the housing 100. Fig. 8 is an enlarged perspective view of the airflow direction adjustment unit 120, and fig. 9 is a plan view thereof. In fig. 9, (a) is a plan view showing wind direction adjusting section 120, (b) is a bottom view of wind direction adjusting section 120, and (c) is a right side view of wind direction adjusting section 120.
The airflow direction adjustment unit 120 is configured such that a plurality of vertical exhaust louvers 122 are arranged in the support plate 121 along the longitudinal direction of the air outlet B. A plurality of longitudinal exhaust windows 122 are erected on the support plate 121 and are swingable within a fixed angle range around an axis perpendicular to the support plate 121. The portion abutting on each axis is at the innermost position (the direction opposite to the Y-axis direction) of the airflow direction adjustment unit 120, and the portion abutting on the tip of the blade is located on the near side (the Y-axis direction). The tip end portions of the respective blades of the plurality of louver blades 122 are connected to the connecting bar 123, and thereby the plurality of louver blades 122 are swung in the wind direction adjusting unit 120 so that the left and right directions of the plurality of louver blades 122 are the same. The wind direction adjustment unit 120 is formed to be almost bilaterally symmetrical.
Of the plurality of vertical exhaust windows 122, two vertical exhaust windows 122a located at both ends of the wind direction adjustment unit 120 have a rotation shaft 124, and the vertical exhaust windows 122a rotate integrally. On the other hand, the vertical louvers 122b other than the both ends (the vertical louvers 122b sandwiched between the vertical louvers 122a positioned at the both ends) are constituted by a shaft 1221, a blade root 1223, and a flexible portion 1222, the shaft 1221 is substantially vertically erected from the support plate 121, the blade root 1223 is a main portion of the vertical louvers 122b, and the flexible portion 1222 is positioned between the shaft 1221 and the blade root 1223. The base (bottom) of the flexible portion 1221 is fixed to the support plate 121. When the vertical louver 122b does not swing in the left-right direction, the flexible portion 1222 and the blade root 1223 are shaped like a plate substantially parallel to the shaft portion 1221. The shaft portion 1221 and the blade root portion 1223 are made of the same material as the flexible portion 1222, and are formed of a thick portion with respect to the flexible portion 1222 and lack of flexibility. Alternatively, the shaft portion 1221 and the blade root portion 1223 may be formed of a portion that is relatively hard to the flexible portion 1222 and lacks flexibility.
The shaft 1221 corresponding to the axis of the vertical louvers 122b is fixed to the support plate 121, but the vertical louvers 122b can be bent left and right by the flexible portion 1222, and the left and right directions of the blade root 1223 can be changed. In this way, the vertical exhaust window 122b is configured to be able to perform the above-described swinging motion (rotational motion) by a simple configuration. Therefore, the entire wind direction adjustment unit 120 has a compact and lightweight structure.
As shown in fig. 9 (b), the rotation shafts 124 of the longitudinal exhaust windows 122a at both ends pass through the lower side of the support plate 121. When the airflow direction adjustment unit 120 is attached to the installation portion 102 of the housing 100, the lower end portion of one of the rotary shafts 124 is configured to engage with the transmission shaft 131 of the drive unit 130.
When the drive unit 130 is mounted on the housing 100, the two transmission shafts 131 are configured to pass through the through holes 103 (see fig. 7) provided in the respective installation portions 102. As shown in fig. 6, the through hole 103 in which the transmission shaft 131 is disposed is positioned at the left end in the right installation portion 102 and at the right end in the left installation portion 102. That is, in the air outlet module 10, two transmission shafts 131 are provided near the center portion of the air outlet B.
In the airflow direction adjusting unit 120 provided in the right installation section 102, the rotating shaft 124 at the left end is engaged with the transmission shaft 131, and no member is engaged with the rotating shaft 124 at the right end. In the wind direction adjustment unit 120 provided in the left installation section 102, the right rotary shaft 124 is engaged with the transmission shaft 131, and no member is engaged with the left rotary shaft 124.
According to the above configuration, the drive unit 130 includes one motor provided between the two airflow direction adjustment units 120, and the drive unit 130 can perform the swinging motion of the vertical exhaust windows 122 of both the left and right airflow direction adjustment units 120. Therefore, it is not necessary to provide a separate drive source for each of the two airflow direction adjusting units 120, and the airflow in the left-right direction can be controlled at low cost.
In this way, according to the above configuration, the vertical exhaust window 122 provided in the outlet B is configured to be divided into two airflow direction adjusting units 120 while being swingable by one motor (drive unit 130), and to be attachable and detachable independently. Further, since the driving force link mechanism between the driving force source and the left and right wind direction adjusting means is formed in the driving means 130 on the main body side of the air conditioner 1, each wind direction adjusting means 120 is lightweight. Therefore, the user can easily detach the vertical exhaust louvers 122, and since the two units are separated, the vertical exhaust louvers are smaller and lighter, and the cleaning or washing work is easier than the case where the vertical exhaust louvers are formed by one unit extending over the entire air outlet B.
Further, since the rotation shafts 124 are formed on both the left and right sides of each wind direction adjustment unit 120, the wind direction adjustment units can be attached to the housing 100 even if they are replaced with each other, and the driving force for the swing motion of the vertical exhaust windows 122 can be transmitted from the driving unit 130 even in this case. Therefore, compared to the case where the airflow direction adjusting means having different shapes are provided separately in the left and right direction, the air conditioner can be further realized at a low cost due to the general use of the components. In addition, the convenience of the user in installation work is also improved.
Further, as compared with the case where the driving force is applied from one end of the air outlet B in order to transmit the driving force to the left and right, the driving force can be transmitted more reliably from the central driving unit 130 to the entire vertical exhaust window.
(method of installing wind direction adjusting unit 120)
A method of attaching the airflow direction adjusting unit 120 to the air conditioner 1 will be described in detail with reference to fig. 7 to 11.
The air conditioner 1 includes a lock mechanism to which the airflow direction adjustment unit 120 can be attached and detached. As shown in fig. 8 and 9, as the lock mechanism, lock levers 126 are provided at both ends of the airflow direction adjusting unit 120, and the lock levers 126 are slidable in the left-right direction (X-axis direction) together with the knob 125. When the lock lever 126 is pushed inward of the airflow direction adjusting unit 120 by the sliding of the knob 125, it is biased outward by a spring. When the user moves the knobs 125 at both ends to the inside of the airflow direction adjusting unit 120 against the urging force in a state where the airflow direction adjusting unit 120 is attached to the main body (housing 100) of the air conditioner 1, the engagement between the lock lever 126 and the lock lever hole 104 provided in the housing 100 of the outlet module 10 is released. In this way, the user can detach the airflow direction adjustment unit 120 from the main body (housing 100) of the air conditioner 1.
Further, a protrusion 127 shown in fig. 9 (c) and the like is provided on the lower surface of the support plate 121 of the wind direction adjustment unit 120, and loosely fits into a loose-fitting hole 105 (refer to fig. 7) provided near the center of the installation portion 102 of the housing 100 when the wind direction adjustment unit 120 is mounted on the main body (housing 100) of the air conditioner 1. When the user removes the airflow direction adjustment unit 120, the protrusion 127 continues to be fitted into the loose-fitting hole 105 even if the airflow direction adjustment unit 120 slightly floats from the installation portion 102 of the housing 100. Therefore, when the user releases the lock mechanism of the airflow direction adjustment unit 120 at the time of detachment, the airflow direction adjustment unit 120 can be prevented from falling off from the main body of the air conditioner 1.
The wind direction adjusting unit 120 is attached to the main body (housing 100) of the air conditioner 1 by engaging the wind direction adjusting unit 120 with a portion of the housing 100 on the back side of the installation portion 102 and performing an operation reverse to the removal of the lock mechanism. In this way, in the air conditioner 1, the airflow direction adjusting unit 120 is configured not to fall off in the attached state, but can be detached more easily by the user's operation of releasing the lock.
The lock mechanism is not limited to the above mechanism, and the wind direction adjusting means 120 may be fixed only by the position of the lock lever without applying a force in the sliding direction of the lock lever. In this case, it is desirable that the knob (catch) is locked so as not to slide when a little force is not applied to the knob in the attached state of the airflow direction adjustment unit 120. The lock mechanism is not limited to being provided on the side of the airflow direction adjustment unit 120, and may be provided on the side of the main body of the air conditioner 1 (the side of the housing 100). In this case, for example, the support plate 13 is sandwiched and fixed by the center portion of the airflow direction adjustment unit 120.
Next, the installation state of the casing 100 to the wind direction adjustment unit 120 will be described in detail. As shown in fig. 9 (a) to (c), the support plate 121 of the airflow direction adjusting unit 120 includes a claw portion 121a protruding rearward on the inner side. When the airflow direction adjustment unit 120 is attached to the installation portion 102 of the housing 100, the claw portion 121a is fitted into the fitting groove 102a (groove) provided on the back side of the installation portion 102, and the airflow direction adjustment unit 120 is fixed. The fitting groove 102a is a groove into which the claw portion 121a is fitted toward the inner side. That is, the depth direction of the groove is parallel to the installation portion 102.
The support plate 121 of the airflow direction adjusting unit 120 has recesses 121b (guide portions) in which a part of the inner side is recessed at two positions that are bilaterally symmetrical. When the wind direction adjusting unit 120 is attached to the installation portion 102 of the housing 100, the respective concave portions 121b are fitted to the positioning protrusions 102c provided at two positions on the back side of the installation portion 102, so that the wind direction adjusting unit 120 is fixed. One of the positioning projections 102c serves as a base of the guide post 106.
In this way, when the airflow direction adjustment unit 120 is attached, it is fixed so as not to move in both the horizontal and vertical directions of the housing 100.
Next, a method of attaching the airflow direction adjustment unit 120 to the main body (housing 100) of the air conditioner 1 by the user will be described.
Fig. 10 is a sectional view of the casing 100 as viewed from the longitudinal direction (X direction) of the air outlet B. The guide post 106 is erected from the installation portion 102 provided on the bottom surface (surface on the negative Z-axis direction side) of the airflow passage inside the outlet port B. The guide post 106 is not perpendicular to the main screen of the setting section 102, and stands upright so as to be inclined in the near direction (Y-axis direction). The ridge on the near side (Y-axis direction) of the guide post 106 is configured as follows. The ridge 106a at a position (first position) separated from the principal plane of the setting portion 102 has a relatively large (deep) angle with respect to the principal plane of the setting portion 102, and the ridge 106b at a position (second position) close to the principal plane of the setting portion 102 has a relatively small (shallow) angle with respect to the principal plane of the setting portion 102. Here, a direction in which the relationship between the ridge line and the direction of the main plane of the installation portion 102 is close to perpendicular is referred to as a deeper angle.
When the inclination is shown from a position perpendicular to the main plane of the installation portion 102, a shallower angle means a state in which the inclination is larger. Here, the ridge line on the near side of the guide post 106 is referred to as a line constituting the most near side (Y-axis direction) of the guide post 106 when viewed from the longitudinal direction (X-direction) of the air outlet B. When the most anterior side of the guide post 106 is constituted by a small surface parallel to the X axis, the ridge line of the anterior side of the guide post 106 is equivalent to the edge of the anterior side (Y axis direction) of the XZ cross section of the small surface. However, the shape of the near side of the guide post 106 is not necessarily limited to the small surface.
Fig. 11 schematically shows a case where the user inserts the airflow direction adjustment unit 120 from the air outlet B to move the airflow direction adjustment unit 120 to the mounting position in order to attach the air conditioner 1 to the main body (housing 100). In the figure, a cross section of the support plate 121 at a position before the claw portion 121a of the wind direction adjustment unit 120 is fitted into the fitting groove 102a of the housing 100 is shown, and a movement locus of the support plate 121 is schematically shown by an arrow a and an arrow B.
When the user inserts the airflow direction adjusting unit 120 into the air outlet B in a state where the left-right position is substantially correct, the guide post 106 loosely fits into the recess 121B of the support plate 121, and the support plate 121 contacts the front surface of the guide post 106. When the user moves the support plate 121 in the direction of the installation portion 102 while keeping the contact state, the guide post 106 is not perpendicular to the main plane of the installation portion 102 but stands upright so as to be inclined in the near direction (Y-axis direction), so that the support plate 121 is gradually and smoothly guided from the near side of the air outlet B toward the installation portion 102.
When the support plate 121 abuts on the first position of the upper portion of the guide post 106, the support plate 121 approaches the installation portion 102 at a deep angle (arrow a) with respect to the main plane of the installation portion 102 according to the angle of the ridge line 106 a. At this time, the trajectory of the tip of the claw portion 121a of the support plate 121 is extended to be closer to the front than the insertion groove 102a.
Further, when the user moves the support plate 121 in the direction of the setting part 102, the support plate 121 abuts on the second position of the lower part of the guide post 106. Then, the support plate 121 approaches the setting part 102 at a shallow angle (arrow B) with respect to the principal plane of the setting part 102 according to the angle of the ridge line 106B. In this way, the claw portion 121a of the final airflow direction adjustment unit 120 is fitted into the fitting groove 102a of the housing 100. In this way, the movement of the airflow direction adjustment unit 120 (support plate 121) is guided by the guide post 106, and the airflow direction adjustment unit 120 is attached to the air conditioner 1 main body (housing 100) at the correct position.
For comparison, fig. 13 illustrates a housing 900 of an air conditioner according to a comparative example in which the angle of the ridge line on the near side of the guide post 906 with respect to the main plane of the installation portion 902 is fixed. At this time, the main portion of the guide post 906 is shaped like a single column of constant thickness. In this case, the moving trajectory (arrow C) of the airflow direction adjusting unit 120 guided by the guide post 906 is a straight line, and the angle with respect to the main plane of the setting portion 902 is fixed. Then, the claw portion 121a of the airflow direction adjusting means 120 is not fitted into the fitting groove 92a of the installation portion 902, and is likely to be mounted on the groove wall portion 902b constituting the fitting groove 902 a. Because the moving locus of the front end of the claw portion 121a is also almost fixed toward the insertion groove 102a. Even when the claw portion 121a is mounted on the groove wall portion 902b as described above, the user may forcibly use the lock mechanism to fix the airflow direction adjustment unit 120. If the air direction adjusting unit 120 is erroneously mounted in this way, the air direction adjusting unit 120 may not be operated correctly during the operation of the air conditioner, and may be a cause of damage to the air direction adjusting unit 120 and the like.
On the other hand, in the air conditioner 1 according to the first embodiment 1, the following problems can be suppressed from occurring: the air direction adjusting unit 120 is not properly mounted and is mounted in an incorrect manner, so that the air conditioner 1 cannot perform its original function, or the air direction adjusting unit is not properly inserted but the user tries to forcibly fix the air direction adjusting unit and is damaged. As shown in fig. 11, when the user moves the airflow direction adjustment unit 120 toward the installation portion 102, the trajectory of the claw portion 121a changes its angle and moves closer to the insertion groove 902a, so that the claw portion 121a is prevented from being placed on the groove wall portion 102b constituting the insertion groove 102a. Therefore, according to the air conditioner 1 of the first embodiment, the claw portion 121a can further accurately attach the airflow direction adjustment unit 120 in the state of being fitted into the fitting groove 902a, and occurrence of such a problem can be suppressed.
In the above description, the angle of the ridge line on the near side of the guide column 106 with respect to the main plane of the setting portion 102 relates to two positions, i.e., the column upper portion (first position) and the column lower portion (second position). However, the angle of the ridge line on the near side of the guide post 106 is not limited to two-stage change, and the angle may be changed in a plurality of stages or may be changed continuously. As shown in fig. 10, one of the configurations for continuously changing the angle is preferably such that the user can more smoothly move the airflow direction adjusting unit 120 for guiding the guide post. The front side ridge of the guide post 106 may be partially linear and partially curved. The angle of the principal plane of the installation portion 102 with respect to the ridge line on the near side of the guide post 106 may be an angle that continuously changes along at least a part of the ridge line.
In the first embodiment, the air outlet B is exemplified by an air outlet module 10 having respective members and integrally formed. However, for example, the air outlet B may be configured by mounting separate members on the upper side (Z-axis square) and the lower side (Z-axis negative direction) of the air outlet B, and such a modification may be suitably adopted by those skilled in the art as a matter of design.
(second embodiment)
Other embodiments of the present invention will be described below. For convenience of explanation, members having the same functions as those described in the above embodiment are given the same reference numerals, and the description thereof will not be repeated.
The air conditioner according to the second embodiment has the same structure as the air conditioner 1 shown in fig. 1 to 11. However, the shape of the support plate 221 of the airflow direction adjustment unit is different from that of the air conditioner 1.
Fig. 12 is a component diagram of a support plate 221 of an airflow direction adjustment unit of an air conditioner according to a second embodiment. Unlike the supporting plate 121 of the first embodiment, the guide part 221b into which the guide post is loosely fitted is formed of two protrusions of the bar of the supporting plate 221 at the time of the mounting operation of the air direction adjusting unit 120. At this time, the position where the support plate 221 abuts against the guide posts is on the back side of the support plate 221 as compared with the support plate 121 of the first embodiment, and accordingly, the mounting position of the guide posts of the housing needs to be moved, but the other configurations are the same as the air conditioner 1 according to the first embodiment.
The air conditioner according to the second embodiment can also obtain the same effects as those of the first embodiment.
