[Embodiment 1]
Hereinafter, Embodiment 1 of the present invention will be described in detail based on FIGS. 1 to 11. In the present embodiment, as shown in the external view of FIG. 3, an air conditioner 1 which is an indoor unit of a separate type wall-mounted air conditioner including an indoor unit and an outdoor unit is described as an example. However, in the air conditioner according to one aspect of the present invention, the air-conditioning airflow outlet B has an elongated shape extending in a predetermined direction, and adjusts the wind direction in the positive direction and the negative direction of the predetermined direction. It suffices that the plurality of wind direction plates include a wind direction adjusting unit arranged on the support plate along the predetermined direction. Therefore, the air conditioner may be a ceiling-mounted type, a floor-mounted type, or an indoor-only machine type (a window-mounted air conditioner or the like) having no outdoor unit.

In addition, although various members of the air conditioner 1 are illustrated in each drawing, description of members that are not related to the embodiment will be omitted. It may be understood that members whose description is omitted are similar to known members. Further, each drawing is intended to schematically explain the configuration showing the shape, structure, positional relationship, etc. of each member, and the air conditioner according to one embodiment of the present invention is provided in each drawing. It is not limited to the configuration shown. These points are the same for the other embodiments.

(Outline of air conditioner 1)
First, the schematic configuration of the air conditioner 1 of the present embodiment will be described with reference to FIGS. 1 to 5.

FIG. 3 is a perspective view showing the external appearance of the air conditioner 1, showing a state in which the air outlet B for air flow is closed. FIG. 4 is a perspective view showing the appearance of the air conditioner 1, showing a state in which the air conditioning operation is performed, the airflow panel 140 is opened, and the airflow outlet B can be visually recognized from the outside. The air conditioner 1 includes a front cabinet 20, a rear cabinet 30, and an outlet module 10, and the housing of the air conditioner 1 is configured by these. FIG. 5 is an exploded view showing the air conditioner 1 by disassembling it into a front cabinet 20, a rear cabinet 30, and an outlet module 10. FIG. 5 also shows the cross-flow fan 40 mounted inside the air conditioner 1.

The rear cabinet 30 is fixed to the wall surface of the room to be air-conditioned. The air conditioner 1 has a rectangular box shape as a whole, and an elongated outlet B is provided in the longitudinal direction thereof. As shown in each figure, the Y direction and the Z direction are defined such that the longitudinal direction of the outlet is the X direction and the XZ plane is parallel to the wall surface on which the rear cabinet 30 is mounted. The direction of the Y axis is from the mounting wall surface to the front surface of the air conditioner 1. When the air conditioner 1 is attached to a wall parallel to the vertical plane so that the X axis is horizontal, the Z axis direction is vertically upward. In the present application, the longitudinal direction (parallel to the X-axis) of the outlet B is referred to as the lateral direction or the left-right direction, the X-axis direction is left, and the direction opposite to the X-axis direction is right. This is because when the user faces the outlet B (front of the air conditioner 1) directly, it corresponds to leftward and rightward as viewed from the user. Further, the direction of the Y-axis is also referred to as frontward, and the direction opposite to the Y-axis is also referred to as backward. This is because when the user directly faces the outlet B (front of the air conditioner 1), they correspond to the front side and the back side as viewed from the user. Therefore, the direction of the airflow at the outlet B is approximately the direction of the Y axis (frontward).

Further, in the present application, a direction parallel to the Z axis may be referred to as a vertical direction, a direction of the Z axis may be referred to as an upward direction, and a direction opposite to the Z axis may be referred to as a downward direction for easy understanding of the description. This is a description method for easy understanding when the air conditioner 1 is mounted on a wall parallel to the vertical plane so that the X axis is horizontal. , But is not limited to this condition.

As shown in FIG. 3 and the like, above the front cabinet 20 and the rear cabinet 30 (in the positive direction of the Z axis), there are provided air intake ports I made up of a large number of crosspieces and gaps between them. As shown in FIG. 5, the cross-flow fan 40 is a horizontal-axis (rotational axis parallel to the X-axis) cylindrical fan that generates an air flow, and surrounds a plurality of blades for sucking and delivering air. Prepare for direction. Although not shown, a heat exchanger is provided so as to surround the upper periphery of the cross-flow fan 40. When the cross-flow fan 40 rotates, air is sucked into the air conditioner 1 through the intake port I, and the sucked air is blown into the room from the blow-out port B through the heat exchanger.

As shown in FIG. 5, the outlet module 10 is provided below the front cabinet 20 (Z-axis negative direction). The outlet module 10 is configured by assembling a frame 100 forming the outlet B with an airflow direction adjusting unit 120 including a plurality of vertical louvers 122 (airflow direction plates), an airflow panel 140, and the like. Details of the structure of the outlet module 10 will be described later. The airflow blown into the room is directed by the airflow panel 140 and the vertical louvers 122 of the wind direction adjustment unit 120.

The opening/closing of the airflow panel 140 is controlled 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, when the airflow panel 140 is closed, the airflow outlet B is closed, and the airflow panel 140 serves as an exterior panel of the air conditioner 1. When the airflow panel 140 rotates in the direction around the X axis and is opened, as shown in FIG. 4, the air outlet B as the airflow passage is exposed. Further, the airflow panel 140 adjusts the vertical direction (parallel to the Z axis) of the airflow blown into the room from the air outlet B according to the rotation angle.

FIG. 2 is a perspective view showing the appearance of the air conditioner 1, and shows a state in which the airflow panel 140 is removed from the air conditioner 1.

The airflow panel 140 is a horizontally long, substantially plate-shaped member, and has a short shaft 141 that is a rotation shaft at one end and an engagement hole 142 at the other end. The short shaft 141 can be pushed inward, and the user can remove the airflow panel 140 from the main body of the air conditioner 1 by removing it from the shaft hole 101 provided in the frame body 100 of the outlet module 10. .. The engagement hole 142 engages with the engagement shaft 151 of the airflow panel rotation unit 150 attached to the air conditioner 1 main body side (frame body 100 side).

The airflow panel 140 receives the driving force in the rotation direction from the engagement shaft 151 of the airflow panel rotation unit 150, and adjusts the rotation angle for adjusting the vertical direction (parallel to the Z axis) of the airflow. The airflow panel 140 is a substantially plate-shaped member and has a relatively simple structure with almost no movable parts inside. Therefore, the airflow panel 140 is light in weight, can be easily attached and detached by the user, and can be easily cleaned and washed.

Inside the air outlet B, a plurality of vertical louvers 122 capable of changing the left-right direction are installed inside the airflow panel 140, and can be easily visually recognized from the outside when the airflow panel 140 is removed. Further, in the blowout port B, an ion generation unit 110 is arranged in the upper part near the center.

FIG. 1 is a perspective view showing an appearance of the air conditioner 1, and shows a state in which the wind direction adjusting unit 120 including a plurality of vertical louvers 122 is further removed from the state of FIG. As is clear from FIGS. 1 and 2, the air conditioner 1 includes two wind direction adjusting units 120 arranged side by side in the outlet B. The wind direction adjusting unit 120 adjusts the left-right direction of the air flow blown into the room from the outlet B by the direction of the vertical louver 122. Inside the outlet B, a guide pillar 106 is vertically formed on the inner side of the position where the wind direction adjusting unit 120 is attached.

(Outline of the wind direction adjustment unit 120 and the outlet module 10)
Next, the configuration of the wind direction adjustment unit 120 and the configuration of the outlet module 10 having the frame body 100 in which the wind direction adjustment unit 120 and the like are arranged will be described with reference to FIGS. 6 to 9.

FIG. 6 is a perspective view showing the outlet module 10, and shows the outlet module 10 in an exploded manner. The outlet module 10 is generally composed of a frame 100, an ion generating unit 110, two wind direction adjusting units 120, a drive unit 130, an air flow panel 140, and an air flow panel rotation unit 150. FIG. 7 is an enlarged perspective view showing a state in which the ion generation unit 110, the drive unit 130, and the left wind direction adjustment unit 120 are attached to the frame body 100. The ion generation unit 110 is an integrated unit that has openings on the left and right for blowing out ions. Each wind direction adjustment unit 120 is detachably fitted into the installation portion 102 at the bottom (the surface on the Z axis negative direction side) of the outlet B in the frame 100. 8 is an enlarged perspective view showing the wind direction adjusting unit 120, and FIG. 9 is a plan view thereof. In FIG. 9, (a) is a top view of the wind direction adjusting unit 120, (b) is a bottom view, and (c) is a right side view.

The wind direction adjusting unit 120 is configured by arranging a plurality of vertical louvers 122 on a support plate 121 along the longitudinal direction of the outlet B. The plurality of vertical louvers 122 stand upright with respect to the support plate 121 and can swing about an axis perpendicular to the support plate 121 within a certain angle range. The part corresponding to each axis is located at the innermost position (the direction opposite to the Y-axis direction) in the wind direction adjusting unit 120, and the part corresponding to the tip of the wing is located on the front side (Y-axis direction). The plurality of vertical louvers 122 are connected at the tip ends of their wings by a connecting bar 123, so that the vertical direction louvers 122 in the wind direction adjusting unit 120 are swung so that the left and right directions are the same. The entire wind direction adjusting unit 120 is formed substantially symmetrically.

Of the plurality of vertical louvers 122, the two vertical louvers 122a located at both ends of the wind direction adjusting unit 120 have a rotation shaft 124, and the entire vertical louvers 122a rotate. On the other hand, the vertical louvers 122b other than both ends (the vertical louvers 122b sandwiched by the vertical louvers 122a located at both ends) include a shaft portion 1221 that stands substantially vertically from the support plate 121, and a blade portion that is a main portion of the vertical louvers 122b. 1223 and a soft portion 1222 between the shaft portion 1221 and the blade portion 1223. The base portion (root portion) of the shaft portion 1221 is fixed to the support plate 121. When the vertical louver 122b does not swing to the left and right, the soft portion 1222 and the blade portion 1223 have a plate shape that is substantially parallel to the shaft portion 1221. The shaft portion 1221 and the blade portion 1223 are made of the same material as that of the soft portion 1222, and are formed of a relatively thick portion having a small thickness and poor flexibility. Alternatively, the shaft portion 1221 and the blade portion 1223 may be portions having poor flexibility formed of a relatively hard material with respect to the soft portion 1222.

The shaft portion 1221 corresponding to the shaft of the vertical louver 122b is fixed to the support plate 121, but the vertical louver 122b can be curved left and right by the soft portion 1222, and the left and right direction of the blade portion 1223 can be changed. You can As described above, the vertical louver 122b is configured to be able to perform the swinging motion (rotating motion) with a simple structure. Therefore, the entire wind direction adjusting unit 120 can be configured to be compact and lightweight.

As shown in FIG. 9B, the rotary shafts 124 of the vertical louvers 122 a at both ends penetrate to the lower side of the support plate 121. When the wind direction adjusting unit 120 is attached to the installation portion 102 of the frame body 100, the lower end portion of one of the rotation shafts 124 is configured to engage with the transmission shaft 131 of the drive unit 130. ..

The drive unit 130 is configured such that the two transmission shafts 131 protrude from the through holes 103 provided in the respective installation portions 102 when the frame 100 is assembled (see FIG. 7 ). As shown in FIG. 6, the position of the through hole 103 in which the transmission shaft 131 is arranged is the left end in the right installation portion 102 and the right end in the left installation portion 102. That is, in the outlet module 10, two transmission shafts 131 are provided near the center of the outlet B.

In the wind direction adjusting unit 120 installed in the installation portion 102 on the right side, the rotary shaft 124 at the left end engages with the transmission shaft 131, and the rotary shaft 124 at the right end does not engage with anything. In the wind direction adjusting unit 120 installed in the installation section 102 on the left side, the rotary shaft 124 at the right end engages with the transmission shaft 131, and the rotary shaft 124 at the left end does not engage with anything.

With the above-described configuration, it is possible to cause the vertical louvers 122 of the left and right wind direction adjusting units 120 to perform the swinging motion by the drive unit 130 including one motor provided between the two wind direction adjusting units 120. Has become. Therefore, it is not necessary to provide a drive source for each of the two wind direction adjusting units 120, and it is possible to control the airflow in the left-right direction at low cost.

As described above, the vertical louver 122 provided in the outlet B is configured to be divided into the two wind direction adjusting units 120 while allowing the swing motion by the one motor (driving unit 130) by the above-described configuration. Each of them can be attached and removed separately. Moreover, since the driving force source and the link mechanism of the driving force between the left and right wind direction adjusting units are formed inside the drive unit 130 on the main body side of the air conditioner 1, each wind direction adjusting unit 120 is lightweight. .. Therefore, the user can easily remove the vertical louver 122, and since the vertical louver 122 is divided into two units, it is smaller and lighter than the case where the vertical louver 122 is composed of one unit over the entire outlet B. Cleaning or washing work is also easier.

Moreover, in each of the wind direction adjusting units 120, since the rotating shafts 124 are formed on both the left and right sides, the rotating shafts 124 can be mounted on the frame body 100 even if they are interchanged with each other. The driving force for the dynamic movement can be transmitted from the driving unit 130. Therefore, as compared with the case where the airflow direction adjusting units having different shapes on the left and right are installed separately, the parts are made common, so that a lower cost air conditioner can be realized. Also, the convenience of the user for the mounting work is enhanced.

Further, since the driving force is separately transmitted to the left and right from the central driving unit 130, the driving force can be more reliably applied to all the vertical louvers as compared with the case where the driving force is applied from one end of the outlet B. Can communicate.

(How to install the wind direction adjustment unit 120)
A method of mounting the wind direction adjusting unit 120 on the main body of the air conditioner 1 will be described in detail with reference to FIGS. 7 to 11.

The air conditioner 1 includes a lock mechanism that allows the wind direction adjustment unit 120 to be attached and detached. As shown in FIG. 8 and FIG. 9, as a lock mechanism, the wind direction adjusting unit 120 is provided at both ends with a knob 126 that is slidable in the left-right direction (X-axis direction) together with the knob 125. When the knob 126 is pushed toward the inside of the wind direction adjusting unit 120 by the sliding of the knob 125, it is biased toward the outside by a spring. When the user moves the knobs 125 at both ends to the inside of the wind direction adjusting unit 120 against the biasing force in a state where the wind direction adjusting unit 120 is attached to the main body of the air conditioner 1 (frame body 100), the outlet module 10 The engaging hole 104 provided in the frame 100 and the engaging hole 126 are disengaged. Then, the user can remove the wind direction adjusting unit 120 from the air conditioner 1 main body (frame 100).

A projection 127 shown in FIG. 9C and the like is provided on the lower surface of the support plate 121 of the wind direction adjusting unit 120, and the wind direction adjusting unit 120 is attached to the main body of the air conditioner 1 (frame 100). When it is installed, it is loosely fitted into the loose fitting hole 105 (see FIG. 7) provided near the center of the installation portion 102 of the frame 100. Thus, when the user removes the wind direction adjusting unit 120, even if the wind direction adjusting unit 120 is slightly floating from the installation portion 102 of the frame 100, the protrusion 127 fits into the loose fitting hole 105. Keep on crowding. Therefore, it is possible to prevent the wind direction adjusting unit 120 from dropping from the main body of the air conditioner 1 when the user releases the lock mechanism of the wind direction adjusting unit 120 during removal.

Further, the wind direction adjusting unit 120 is attached to the main body of the air conditioner 1 (the frame body 100) by engaging the wind direction adjusting unit 120 at the rear side of the installation portion 102 of the frame body 100, and the lock mechanism is the reverse of the removal. It can be performed by performing an operation. In this way, in the air conditioner 1, the wind direction adjusting unit 120 does not come off in the mounted state, but can be removed relatively easily by the user's unlocking operation.

The lock mechanism is not limited to the one described above, and may be one in which the wind direction adjusting unit 120 is simply fixed depending on the position of the boot without being given a biasing force in the sliding direction of the boot. Even in that case, it is preferable that the wind direction adjusting unit 120 is locked so that it does not slide unless a little force is applied to the knob when the wind direction adjusting unit 120 is attached. Further, the lock mechanism is not limited to being provided on the wind direction adjusting unit 120 side, but may be provided on the air conditioner 1 main body side (frame body 100 side). In that case, for example, a mechanism for sandwiching and fixing the support plate 121 at the central portion of the wind direction adjusting unit 120 can be used.

Next, the installation state of the wind direction adjusting unit 120 on the frame 100 will be described in detail. As shown in FIGS. 9A to 9C, the support plate 121 of the wind direction adjusting unit 120 includes a claw portion 121a that protrudes inward on the back side. When the wind direction adjustment unit 120 is attached to the installation portion 102 of the frame 100, the wind direction adjustment unit 120 is fixed so that the claw portion 121a fits into the insertion groove 102a (groove) provided on the back side of the installation portion 102. To be done. The fitting groove 102a is a groove into which the claw portion 121a is fitted toward the back side. That is, the depth direction of the groove is parallel to the installation portion 102.

Further, the support plate 121 of the wind direction adjusting unit 120 has two recesses 121b (guide portions) in which a part of the inner side is recessed at symmetrical positions. When the wind direction adjustment unit 120 is mounted on the installation portion 102 of the frame 100, the two recesses 121b are aligned with the two positioning protrusions 102c provided on the back side of the installation portion 102 so that the wind direction adjustment unit 120 can be adjusted. 120 is fixed. One of the positioning protrusions 102c forms the base of the guide pillar 106.

As described above, when the wind direction adjusting unit 120 is mounted, it is fixed to the frame body 100 so as not to move in the left-right direction and the vertical direction.

Subsequently, a mounting method when the user mounts the wind direction adjusting unit 120 on the main body of the air conditioner 1 (frame 100) will be described.

FIG. 10 is a cross-sectional view of the frame body 100 observed from the longitudinal direction (X direction) of the outlet B. Inside the outlet B, a guide pillar 106 stands up from an installation portion 102 provided on the bottom surface (surface on the Z axis negative direction side) of the airflow passage. The guide pillar 106 is not perpendicular to the main surface of the installation portion 102, but stands up so as to be inclined toward the front (Y-axis direction). The ridgeline on the front side (Y-axis direction) of the guide pillar 106 is configured as follows. The ridge line 106a at a position (first position) away from the main surface of the installation portion 102 has a relatively large (deep) angle with respect to the main surface of the installation portion 102 and is close to the main surface of the installation portion 102. The ridge line 106b at the position (second position) has a relatively small (shallow) angle with respect to the main surface of the installation portion 102. Here, the direction in which the direction of the ridgeline with respect to the main surface of the installation portion 102 is close to vertical is referred to as a deeper angle. When expressed by an inclination from a position perpendicular to the main surface of the installation portion 102, a shallower angle means a state where the inclination is large. Further, here, the ridgeline on the front side of the guide pillar 106 refers to a line forming the most front side (Y-axis direction) portion of the guide pillar 106 when observed from the longitudinal direction (X direction) of the outlet B. ing. When the foremost side of the guide pillar 106 is configured by a small surface parallel to the X axis, the ridgeline on the near side of the guide pillar 106 is equal to the edge of the small surface on the near side (Y-axis direction) of the XZ cross section. However, the shape of the front side of the guide pillar 106 is not necessarily limited to be configured by such a facet.

FIG. 11 schematically shows a situation in which the user inserts the wind direction adjusting unit 120 from the outlet B to move it to the mounting position in order to attach it to the main body (frame 100) of the air conditioner 1. In the figure, a cross section of the support plate 121 at a position immediately before the claw portion 121a of the wind direction adjusting unit 120 is fitted into the fitting groove 102a of the frame body 100 is shown, and the locus of movement of the support plate 121 is schematic. Are indicated by arrows A and B.

When the user inserts the wind direction adjusting unit 120 into the back of the outlet B with the right and left positions being approximately correct, the guide pillar 106 is loosely fitted into the recess 121b of the support plate 121, and the support plate 121 is guided by the guide plate 121. It contacts the front surface of 106. When the user moves the support plate 121 toward the installation portion 102 while maintaining the contact state, the guide pillar 106 is inclined not toward the main surface of the installation portion 102 but in the front direction (Y-axis direction). Since it stands up like this, the support plate 121 is naturally guided gradually toward the installation portion 102 from the front side of the outlet.

When the support plate 121 is in contact with the upper portion of the guide pillar 106 at the first position, the support plate 121 has a deep angle (arrow A) with respect to the main surface of the installation portion 102 according to the angle of the ridge 106a. Approaching 102. At this time, if the locus of the tip of the claw portion 121a of the support plate 121 is extended, it will be in front of the fitting groove 102a.

When the user further moves the support plate 121 toward the installation portion 102, the support plate 121 comes into contact with the lower portion of the guide pillar 106 at the second position. Then, according to the angle of the ridge line 106b, the support plate 121 comes closer to the installation portion 102 at a shallow angle (arrow B) with respect to the main surface of the installation portion 102. Then, finally, the claw portion 121a of the wind direction adjusting unit 120 is fitted into the fitting groove 102a of the frame body 100. In this way, the guide pillar 106 guides the movement of the wind direction adjusting unit 120 (support plate 121), and the wind direction adjusting unit 120 is attached to the main body (frame 100) of the air conditioner 1 at the correct position.

For comparison, FIG. 13 illustrates a frame body 900 of an air conditioner of a comparative example in which the angle of the ridgeline on the front side of the guide pillar 906 with respect to the main surface of the installation portion 902 is constant. At this time, the shape of the main portion of the guide pillar 906 is simply a column having a constant thickness. In this case, the movement trajectory (arrow C) of the wind direction adjusting unit 120 guided by the guide pillar 906 is linear, and the angle of the installation portion 902 with respect to the main surface is constant. Then, the claw portion 121a of the wind direction adjusting unit 120 is likely to ride on the groove wall portion 902b forming the fitting groove 902a without fitting in the fitting groove 902a of the installation portion 902. This is because the locus of movement of the tip of the claw portion 121a is substantially constant toward the back of the fitting groove 102a. Even when the claw portion 121a rides on the groove wall portion 902b in this manner, the user may force the air direction adjusting unit 120 to be fixed by using the lock mechanism. If such an incorrect mounting is performed, not only does the wind direction adjusting unit 120 not operate properly during operation of the air conditioner, but it may also cause damage to the wind direction adjusting unit 120 and the like.

On the other hand, in the air conditioner 1 according to the first embodiment, the wind direction adjusting unit 120 is not properly attached, and the air conditioner 1 is not installed so that the original function of the air conditioner 1 is not exhibited, or the wind direction adjusting unit is not fitted properly. Even if there is no such problem, the occurrence of trouble such as breakage caused by the user trying to forcibly fix the wind direction adjustment unit is suppressed. As shown in FIG. 11, when the user moves the wind direction adjusting unit 120 closer to the installation portion 102, the trajectory of the claw portion 121a approaches the fitting groove 902a while changing the angle. This is because the occurrence of the phenomenon of riding on the groove wall portion 102b forming the fitting groove 102a is suppressed. Therefore, according to the air conditioner 1 of the first embodiment, the wind direction adjusting unit 120 can be more surely and correctly mounted with the claw portion 121a fitted in the fitting groove 902a, and the occurrence of such a trouble is suppressed.

In the above description, regarding the angle of the ridgeline on the front side of the guide pillar 106 with respect to the main surface of the installation portion 102, reference is made to two places, that is, the guide pillar upper portion (first position) and the guide pillar lower portion (second position). It was done. However, the angle of the ridgeline on the front side of the guide pillar 106 is not limited to the one that changes in two steps, and the angle may change in multiple steps or even continuously. As shown in FIG. 10, it is preferable that the angle is continuously changed, because the user can move the wind direction adjusting unit 120 while being guided by the guide pillar more smoothly. The ridgeline on the front side of the guide pillar 106 may be partially straight and partially curved. The angle of the ridgeline on the front side of the guide pillar 106 with respect to the main surface of the installation portion 102 may continuously change along at least a part of the ridgeline.

In the first embodiment, an example has been shown in which the blowout port B is integrated by the blowout port module 10 including each member. However, for example, the outlet B may be configured by assembling separate members on the upper side (Z-axis positive direction) and the lower side (Z-axis negative direction) of the outlet B. As a design item, those skilled in the art can appropriately adopt it.

[Embodiment 2]
Another embodiment of the present invention will be described below. For convenience of description, members having the same functions as the members described in the above embodiment will be designated by 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 FIGS. However, the shape of the support plate 221 of the wind direction adjusting unit is different from that of the air conditioner 1.

FIG. 12 is a component diagram of the support plate 221 of the wind direction adjustment unit of the air conditioner according to the second embodiment. Unlike the support plate 121 of the first embodiment, the guide portion 221b into which the guide pillar is loosely fitted when the operation of mounting the wind direction adjustment unit 120 is configured by two protrusions on the sides of the support plate 221. In this case, the position where the support plate 221 abuts on the guide pillar is on the back side of the support plate 221 as compared with the support plate 121 of the first embodiment. Therefore, the mounting position of the guide pillar on the frame body needs to be moved accordingly. Although there are some, other configurations can be configured similarly to 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 described in the first embodiment.
