FIG. 9 is a perspective view and FIG. (A) is a front view, (b) is a perspective view), and FIG. 10 shows a connecting portion between the rack 20 and the cam 21 of the floor-mounted air conditioner 100. 11 is a perspective view of the shutter 9 of the floor-mounted air conditioner 100 viewed from the back side, and FIG. 12 shows the shutter rails 11 and 12 and the rack rails 18 and 19 of the floor-mounted air conditioner 100. FIG. 13 is a side cross-sectional view illustrating the operation of the lower part of the shutter 9 of the floor type air conditioner 100, the cam 21, and the rack rail 18, and FIG. 14 is a shutter according to the operation of the floor type air conditioner 100. 9 is a flowchart for explaining an opening / closing operation of FIG.

  In FIG. 1, an air conditioner main body 1 that is an indoor unit of a floor-mounted air conditioner 100 includes a suction port 3 (one side in FIG. 1) opened on the left and right side surfaces of a suction grill 2 provided below the front surface by the rotation of a blower fan 5. The indoor air sucked in through the filter 4 for removing dust from the two is cooled or heated by an internal heat exchanger (not shown) and is discharged from the upper outlet 6 (hidden by the shutter 9 in FIG. 1). It blows out indoors and performs indoor cooling and heating.

  Further, a front panel 7 is provided between the air outlet 6 and the suction grill 2, and a controller unit 8 for controlling the operation of the floor-mounted air conditioner 100 is provided below the front panel 7.

  As shown in FIGS. 2 (a) and 2 (b), the air outlet 6 has an air outlet that is substantially flush with the front panel 7 when the floor-mounted air conditioner 100 is stopped. The design is good by closing 6 so that foreign matter does not enter the air outlet 6, and when the floor-mounted air conditioner 100 is operated, it is automatically lowered and hidden behind the front panel 7 to open the air outlet 6. An automatic opening / closing shutter 9 is provided.

  In the example shown in FIG. 1, not only the front panel 7 but also the suction ports 3 of the suction grill 2 are provided on both left and right sides so that they are not noticeable when viewed from the front. As shown in FIGS. 1 and 2 (a), the air conditioner main body 1 has a front surface with few irregularities and a very good appearance.

  As shown in FIG. 2, side covers 13 and 14 having the same width as the front and rear width of the side surface of the suction grill 2 are provided on the left and right sides of the shutter 9 and the front panel 7 to further improve the design.

  As shown in FIG. 2B, the air outlet 6 is composed of a louver unit 10. The louver unit 10 is provided with a plurality of horizontal louvers 10a that deflect the wind direction up and down, and a plurality of vertical louvers (not shown) that deflect the wind direction left and right behind the louver unit 10, and the inclination of the horizontal louver 10a and the vertical louver is adjusted. By changing, the direction of the air blown out from the air outlet 6 can be adjusted to the user's preference.

  The configuration other than the internal components will be described with reference to FIG. The cabinet 1a of the air conditioner body 1 is composed of left and right side surfaces, an upper surface, a back surface, and a pedestal.

  The louver unit 10 is attached to the cabinet 1a. On both the left and right sides of the louver unit 10, shutter rails 11 and 12 having a substantially symmetrical shape that guides up and down so as to open and close the shutter 9 are attached by screw fastening or the like.

  Inside each of the shutter rails 11 and 12, rail grooves 11a and 12a are formed, in which a pair of pins 9a provided on the upper left and right side surfaces of the shutter 9 enter and slide up and down. Inclined portions 11b and 12b are formed in the upper part of the rail grooves 11a and 12a so as to move to the front side as they go upward. When the shutter 9 rises and closes the outlet 6, the upper part of the shutter 9 moves forward by about 15 mm. Thus, the upper portion of the shutter 9 is set to the same front position as that of the front panel 7.

  Next, the rear panel 15 provided under the louver unit 10 and disposed behind the front panel 7 and attached to the cabinet body 1a will be described. The rear panel 15 is fixed to the cabinet 1a to strengthen the air conditioner main body 1 and attach components for moving the shutter 9 up and down. Further, the rear panel 15 forms a space for storing the lowered shutter 9 with the front panel 7 when the shutter 9 is opened.

  A motor 17 arranged so that the pinion 16 set so that the ascending / descending speed of the shutter 9 is about 20 to 30 mm / s can be seen near the center of the rear panel 15 from the back side of the rear panel 15. It is concluded with. As shown in FIG. 8, the pinion 16 is inserted into the shaft of the motor 17 and fixed. A vertical row of gears 20a meshing with the teeth of the pinion 16 is formed on the back side between the left and right widths (see FIG. 6), and the pinion 16 is rotated by the motor 17 so as to move vertically. A wide rack 20 is provided.

  The rack rails 18 and 19 that are substantially symmetrical in the left-right direction and guide the rack 20 are fixed to the front surface of the rear panel 15 by screws or the like, and the rack 20 is vertically moved to the rear panel 15 by the rack rails 18 and 19. (See FIG. 4).

  Since the rack 20 has a relatively wide left and right width so that the pinion 16 is housed within the left and right width of the rack 20 (see FIG. 7), the pinion 16 and the coupling portion of the teeth of the pinion 16 are provided. The rack 20 is protected by being hidden in the rack 20, so that it is possible to prevent a foreign matter from entering the meshing portion and causing a malfunction, and the rack 20 can be reliably moved up and down by the relatively wide rack 20. Further, the motor 17 and the pinion 16 can be easily detached by adopting a screw fastening configuration from the back side of the rear panel 15.

  Next, the structure of the rack 20 that moves up and down to raise and lower the shutter 9 will be described in more detail with reference to FIG. The rack 20 is formed in a shape that is long in the vertical direction, and includes two slide pins 20b on each side that protrude left and right at the top and bottom of the left and right side surfaces. The two slide pins 20b on each side enter and guide the opposing rail grooves 18a and 19a formed on the upper and lower sides of the rack rails 18 and 19, so that the rack 20 is firmly secured in the left-right direction and the front-rear direction. In the held state, the rack 20 is moved up and down while being held on the front surface of the rear panel 15 by the meshing of the gear 20a by the rotation and reverse rotation of the pinion 16.

  Further, as shown in FIG. 3 and FIG. 7, to prevent the rack 20 from moving to the left and right, a presser pin 30 is provided on the right side of the pinion 16 on the rear panel 15 side, and the teeth of the pinion 16 are connected to the gear 20 a of the rack 20. When the guide pins 20f formed on the back surface of the rack 20 are pressed against the presser pins 30 when they are engaged and moved up and down, the rack 20 is held so as not to move left and right. The pinion 16 can be moved up and down by the rotation of the pinion 16.

  Further, on both sides of the upper portion of the rack 20 made of a plastic member, there are integrally mounted mounting portions 20c that are rack-side connecting portions for mounting two cams 21 that are connecting members connected to the shutter 9 so as to be rotatable in the front-rear direction. Projecting to both sides. Each of the mounting portions 20c is erected upward relative to each other, and is integrally formed with the rack 20 by a standing piece 20e provided with a mounting hole 20d that is opposed to each other. In addition, the rack 20 is arranged so that the left and right positions of the mounting portion 20c are substantially the same in the left and right directions from the center in the left and right direction of the shutter 9 so that the right and left balance with respect to the width of the shutter 9 is good.

  Next, the detailed structure of the cam 21 will be described with reference to FIG. The two cams 21 which are relatively small parts are the same in this embodiment, and are formed by a plastic member made of a material that easily slides so as to be easily rotated at the connecting portion of the rack 20 and the shutter 9. ing. The cam 21 has a rack-side mounting shaft 22 that is a rack-side mounting portion that protrudes to the left and right sides, which is a mounting portion that is pivotally connected to the rack 20 on one side, and the rack-side mounting shaft 22 on the other side in the vertical direction. On the same straight line, there is provided a shutter side mounting shaft 23 that is a shutter side mounting portion that protrudes to the left and right sides, which is a mounting portion that is pivotally connected to the lower portion of the shutter 9 in the front-rear direction.

  Further, the rack-side mounting shaft 22 and the shutter-side mounting shaft 23 are formed behind the straight line connecting the rack-side mounting shaft 22 and the shutter-side mounting shaft 23 between the rack-side mounting shaft 22 and the shutter-side mounting shaft 23. A presser shaft 24 for presser that protrudes by about 10 mm to the left and right sides is formed integrally, and the cam 21 itself is formed in a substantially bilaterally symmetrical shape around the center. In this way, the positional relationship between the shafts of the presser shaft 24, the rack-side mounting shaft 22, and the shutter-side mounting shaft 23 is arranged in a triangular shape. Further, the rack-side mounting portion 20c and the shutter-side mounting portion 9e are arranged so that the front-rear position of the rack-side mounting shaft 22 is behind the shutter-side mounting shaft 23.

  Further, the base portion 22a of the left and right shafts is formed thicker than the diameter dimension of the mounting hole 20d so that the shape of the rack side mounting shaft 22 is firmly connected to the mounting portion 20c which is the connecting portion of the rack 20 (φ10 mm). Degree), and is formed so as to be sandwiched between the standing pieces 20e.

  A stepped tip 22b that is fitted and connected to the mounting hole 20d and is rotated is formed to have substantially the same diameter as the mounting hole 20d. Then, as shown in FIG. 10, the rack-side mounting shaft 22 of the cam 21 is pushed into the left and right mounting portions 20c of the rack 20 between the standing pieces 20e, and the tip portion 22b of the rack-side mounting shaft 22 fits into the mounting hole 20d. The cam 21 is firmly connected to the rack 20 so as to be pivotable back and forth.

  Further, the shape of the shutter side mounting shaft 23 is also formed to have substantially the same thickness and dimensions as the rack side mounting shaft 22. The attachment of the cam 21 on the shutter 9 side will be described. As shown in the perspective view of the shutter 9 shown in FIG. 11, a stepped portion 9 b is formed at the lower part of the shutter 9 made of a plastic member so as to be lowered rearward from the front surface of the shutter 9 over the entire width of the shutter. Is done. The stepped portion 9b is formed in two steps, an upper stepped portion 9d and a lower stepped portion 9c below, and an upper stepped portion 9d that is recessed several millimeters behind the lower stepped portion 9c.

  And the attachment part 9e which is a shutter side connection part which connects the shutter side attachment axis | shaft 23 of the cam 21 to the front-back direction so that rotation is possible in the step part 9b which is the lower part of this shutter 9 back surface is formed in right and left. . The left and right attachment portions 9e have substantially the same shape as the attachment portion 20c of the rack 20, and are provided at the same positions on the left and right as the left and right attachment portions 20c of the rack 20. Similarly to the mounting portion 20c of the rack 20, they are integrally formed with the shutter 9 by standing pieces 9g that are erected upward relative to each other and provided with opposing mounting holes 9f for mounting.

  In this embodiment, the mounting hole 20d has the same round hole shape as the tip portion 22b. However, another shape is possible as long as the fitted tip portion 22b can be securely rotated and prevented from coming off. Alternatively, for example, the mounting hole 20d may be formed in a U shape, and a protrusion or the like that prevents the fitted end portion 22b from rotating firmly and coming off may be formed and provided integrally with the rack 20.

  Then, the base portion 23a of the left and right shafts has a diameter of the mounting hole 9f so that the shutter side mounting shaft 23 formed in substantially the same shape as the rack side mounting shaft 22 is also firmly connected to the mounting portion 9e of the shutter 9. It is formed with a thicker diameter (about φ10 mm) and is sandwiched between the mounting pieces 9g.

  A stepped tip portion 23b that is fitted and connected to the attachment hole 9f and rotated is formed to have substantially the same diameter as the attachment hole 9f. Then, similarly to the mounting portion 20c of the rack 20, the shutter side mounting shaft 23 of the cam 21 is pushed into the left and right mounting portions 9e of the shutter 9 between the standing pieces 9g, and the distal end portion 23b of the shutter side mounting shaft 23 is mounted. The cam 21 is firmly connected to the shutter 9 so as to be rotatable in the front-rear direction, and the lower portion of the shutter 9 is firmly connected to the rack 20 via the cam 21. The movement is restricted to the left and right. In this way, since the mounting portion 9e of the shutter 9 is connected to the left and right substantially on the same straight line from the mounting portion 20c of the rack 20 via the cam 21, the lower portion of the shutter 9 is smoothly moved by the rising of the rack 20. It can be pushed up to.

  Next, the presser shaft 24 protrudes further to the left and right sides from the rack-side mounting shaft 22 and the shutter-side mounting shaft 23 of the cam 21 and has a diameter larger than the rack-side mounting shaft 22 and the shutter-side mounting shaft 23. Explain how it works. The opposing left and right rack rails 18 and 19 are formed with front walls 18c and 19c that prevent the presser shaft 24 from protruding forward, so that the left and right racks extend from the top to the middle as shown in FIG. The presser shaft guide grooves 18b and 19b formed integrally with the rail grooves 18a and 19a for the rack 20 are formed integrally with the rack rails 18 and 19, respectively.

  The presser shaft 24 of the right cam 21 is guided by the right shaft entering the presser shaft guide groove 19b of the right rack rail 19, and the presser shaft 24 of the left cam 21 is the left shaft. Enters the guide shaft guide groove 18b of the left rack rail 18 and is guided.

  Further, the open inclined portions 18d and 19d are formed so that the front wall portions of the upper portions of the front walls 18c and 19c of the presser shaft guide grooves 18b and 19b shift to the front side as they go upward. When the presser shaft 24 is lifted up to 18d and 19d, the presser shaft 24 protrudes to the front side by the open inclined portions 18d and 19d, and the presser shaft 24 is opened forward to rotate the cam 21 forward and the shutter 9 The upper part of the shutter 9 is pushed forward, and the upper side of the upper stepped portion 9d of the shutter 9 is located at the same front surface position as the front panel 7 so that the air outlet 6 can be closed by the shutter 9.

  The operation under the shutter 9 will be described in more detail. FIG. 13 is an explanatory side sectional view for explaining the operation of the cam 21 and the shutter 9 at the upper part of the left rack rail 18. The cam 21 is indicated by a one-dot chain line. Moreover, the rack 20 has shown only the upper slide pin 20b with the dashed-dotted line. The operation when the shutter 9 is raised from the position A to the position B in the figure will be described.

  The shutter 9 is located behind the front panel 7 until the position of the shutter 9 is about A in the figure, and the shutter 9 rises behind the front panel. At this time, the rack-side mounting shaft 22 that receives the weight of the shutter 9 is formed so that the mounting portion 20c is positioned behind the shutter-side mounting shaft 23, so that the cam 21 always rotates forward due to the weight of the shutter 9. The power to do is added. However, since the presser shaft 24 remains pressed by the front wall 18c of the presser shaft guide groove 18b, the shutter 9 does not move forward even when the shutter 9 is raised.

  When the shutter 9 is further raised to the position B in the figure by raising the rack 20, the presser shaft 24 reaches the open inclined portion 18d of the presser shaft guide groove 18b and moves forward along the open inclined portion 18d. The cam 21 rotates forward due to the weight of the shutter 9 and pushes the lower portion of the shutter 9 so that the shutter 9 protrudes forward. The upper portion above the upper stepped portion 9d of the shutter 9 is at the same front position as the front panel 7, and the outlet 6 can be closed. In the description of FIG. 13, the left rack rail 18 has been described, but the opposite right rack rail 19 simultaneously operates so that the shutter 9 protrudes forward similarly by the cam 21.

  Further, when the lower part of the shutter 9 moves forward in this manner, the upper pin 9a of the upper part of the shutter 9 is also moved forward by the inclined portions 11b and 12b of the rail grooves 11a and 12a of the shutter rails 11 and 12, as described above. The part which covers the blower outlet 6 of the shutter 9 becomes the front and back same plane as the front panel 7.

  Further, in this embodiment, the stepped portion 9b overlaps the front panel 7 when the stepped portion 9b is formed in the lower portion of the shutter 9 and the shutter 9 completely closes the outlet 6. The interior of the air conditioner body 1 is not seen from the gap above the stepped portion 9b of the front panel 7 and the shutter 9.

  Further, since the stepped portion 9b is also formed in two steps and the upper stepped portion 9d is formed deeper than the lower stepped portion 9c, the corners of the upper portion of the front panel 7 and the stepped portion 9b of the shutter 9 are front and rear. When moving up and down while moving, it is difficult to interfere with the front panel 7, the shape of the upper portion of the front panel 7 can be easily formed, and the strength in the left-right width direction of the shutter 9 can be increased by the deep upper stepped portion 9 d.

  In the above description, the case where the shutter 9 is raised and the outlet 6 is closed has been described. However, when the shutter 9 is opened, each component moves the shutter 9 backward by the reverse operation, and the rear of the front panel 7. Can be stored.

  Further, in this example, when the presser shaft 24 is raised to a predetermined position, the front walls 18c and 19c that prevent the cam 21 from rotating forward and are opened so as to be rotated forward by the opening inclined portions 18d and 19d are provided. In order to form them, the guide rails 18b and 19b for the presser shaft are formed integrally with the rack rails 18 and 19 to reduce the number of parts and are easy to make. However, the rack rails 18 and 19 are different from the presser rails 19 and 19. The shaft guide grooves 18b and 19b may be formed separately, or only the front wall portions 18c and 19c may be formed. The shaft guide grooves 18b and 19b are not necessarily formed into a groove shape.

  Next, a description will be given of suitable dimensions that allow the rack 9 and the cam 21 to move up and down smoothly without shaking the shutter 9 from side to side. As shown in FIG. 5, the dimension E between the left and right mounting portions 20c, which are connected to the left and right cams 21 and project from the left and right sides of the upper portion of the rack 20, is the same as that of the shutter 9 shown in FIG. It is a relatively narrow width in the range of 1/4 to 2/4 with respect to the width G dimension. In addition, the dimension F between the left and right mounting portions 9e which are integrally formed on the back side of the shutter 9 made of a plastic member and which is connected to the other of the left and right cams 21 is similarly the width G dimension of the shutter 9. On the other hand, it has been found that the shutter 9 can be raised and lowered sufficiently smoothly with a relatively narrow width in the range of 1/4 to 2/4.

  The dimension E between the mounting portions 20c of the rack 20 to which the upper and lower sides of the left and right cams 21 are respectively connected and the dimension F between the mounting portions 9e of the shutter 9 are about 1/4 of the width dimension G of the shutter 9. If it is narrow, the width of the rack 20 becomes too narrow and the rack 20 tends to tilt, making it difficult for the rack 20 to move up and down. It becomes difficult to push up.

  Further, the dimension E and the dimension F are preferably up to about half of the G dimension. If the dimension E between the mounting parts 20c and the dimension F between the mounting parts 9e of the shutter 9 are larger than 2/4 of the width dimension G of the shutter 9, the left and right widths of the rack 20 become wider and the rack 20 becomes larger and heavier. As a result, it becomes easy to incline, and a problem arises in that a motor with a large strong torque is required to raise and lower the large and heavy rack 20 and unnecessary energy is required.

For this reason, the mounting portion 20c interval size E of the rack 20 and the mounting portion 9e interval size F of the shutter 9 are relatively set to 1/4 to 2/4 of the left-right width G size of the shutter 9 as in the following equation. A narrow range (a range of about 25% to about 50%) is preferable.
(G * 1/4) ≦ E ≦ (G * 2/4)
(G * 1/4) ≦ F ≦ (G * 2/4)
With such dimensions, the tilt of the left and right attachment portions 20c, which are the connecting portions at the top of the rack 20, can be prevented, and the shutter 9 can be smoothly pushed up via the left and right cams 21. Can be done smoothly.
Note that the dimension E and the dimension F are set to the same left and right positions by the cam 21.

As described above, the mounting portion 20c interval dimension E of the rack 20 and the mounting portion 9e interval dimension F of the shutter 9 are made the same, so that the left and right positions are exactly the same. It is easy to be transmitted to the shutter 9 via the cam 21, and the shutter 9 can be raised and lowered smoothly.
Note that the attachment portion 20c interval dimension E and the attachment portion 9e interval dimension F may be slightly different by changing the shape of the cam 21.

  As an example, the width G of the shutter 9 is 500 mm, the dimension E between the rack 20 mounting portions 20 c and the dimension G between the shutter 9 mounting portions 9 e are 190 mm, and the shutter 9 is moved up and down smoothly by raising and lowering the rack 20. It was possible.

  In the above embodiment, the cam 21 has a substantially symmetrical shape, and the left and right cams 21 are the same, and the cost of the wrong assembly and mass production is low. The right cam 21 may not have the left presser shaft 24, and the left cam 21 may not have the right presser shaft 24, and may have separate left and right cam shapes.
