Definitions
- the present invention relates to an air conditioner.
- the air conditioner disclosed in Patent Literature 1 Japanese Utility Model Application No. 4-20923
- the air conditioner disclosed in Patent Literature 1 comprises a conditioner main body (equivalent to the main body) in which an intake port and a discharge port are formed in a forward surface (equivalent to the front surface), and a panel for covering the entire forward surface of the conditioner main body.
- the panel can move between a close position of closing off the intake port and the discharge port, and an open position of opening up the intake port and the discharge port. Therefore, in this air conditioner, the intake port and the discharge port can be blocked or opened up by moving the panel.
- an object of the present invention is to provide an indoor unit of an air conditioner in which the design can be improved.
- An indoor unit of an air conditioner comprises a main body and a movable panel.
- a front surface intake port and a front surface discharge port are formed in a front surface of the main body.
- the movable panel has a front surface panel part and a side surface panel part.
- the front surface panel part is positioned in front of the main body.
- the side surface panel part is formed continuing rearward from both ends of the front surface panel part.
- the side surface panel part is formed continuing rearward from both ends of the front surface panel part. Therefore, when the movable panel assumes the operation-stopped state, the main body can be covered from the front to the sides of the main body. Consequently, when the main body in which the movable panel has assumed the operation-stopped state is viewed at an angle, it is easier to make the joint between the movable panel and the main body not stand out than in a case of a configuration in which the movable panel covers only the front of the main body, for example.
- the design can thereby be improved.
- An indoor unit of an air conditioner according to a second aspect is the indoor unit of an air conditioner according to the first aspect, further comprising a drive mechanism.
- the drive mechanism has a drive component for moving the movable panel.
- the movable panel assumes an operating state of opening up the front surface intake port and the front surface discharge port by moving diagonally upward from the operation-stopped state.
- the side surface panel part is positioned to the side of the drive component.
- the side surface panel part is positioned to the side of the drive component. Therefore, the quantity of air drawn in from the side can be reduced in comparison with a case in which the side surface panel part is not positioned to the side of the drive component, for example.
- An indoor unit of an air conditioner according to a third aspect is the indoor unit of an air conditioner according to the second aspect, wherein the drive component includes a panel support arm.
- the panel support arm is connected to the movable panel.
- the panel support arm can be switched between a first state of being accommodated in the main body and a second state of being separated from the main body. Furthermore, the panel support arm is in the second state when the movable panel has assumed the operating state.
- the side surface panel part is disposed so as to cover the panel support arm being in the second state in a side view.
- the panel side surface part is disposed so as to cover the panel support arm separated from the main body in a side view. Therefore, the design during operation can be improved.
- An air-conditioning indoor unit comprises a first member, a second member, a drive member, a motor, an indoor unit main body, and a panel.
- the first member has a first groove and a second groove.
- the first groove includes a first lower curved part.
- the second groove includes a second lower curved part and a second higher curved part.
- the second lower curved part is in a position separated from the first lower curved part.
- the second higher curved part extends from a first end part which is an end part of the second lower curved part.
- the second higher curved part also has a greater curvature than the second lower curved part.
- the second member has a first sliding member and a second sliding member. The first sliding member moves along the first groove.
- the second sliding member moves along the second groove.
- the drive member moves the first member relative to the second member so that the first sliding member slides against the first groove and the second sliding member slides against the second groove.
- the motor drives the drive member.
- the indoor unit main body is connected to the second member.
- the panel is connected with the first member. The panel varies an orientation relative to the indoor unit main body due to the first member moving relative to the second member.
- the drive member contacts the first member.
- the first member rotatably moves about the first sliding member as a rotational fulcrum when the second sliding member moves from the second lower curved part to the second higher curved part.
- a load imposed on the motor when the second sliding member is positioned in a second groove end part which is an end part of the second groove on the side including the second higher curved part is less than a load imposed on the motor when the second sliding member is positioned in the first end part of the second lower curved part.
- JP 2006 064361 discloses a base member detachable from a front face side of an air conditioning main body, the base member being mounted on a rear side of the front panel covering a front face of the air conditioner main body.
- the front panel is connected with the base member through right and left operation arms on its rear side, and reciprocable between a first state for narrowing an air suction part and a second state for expanding the air suction part, an air suction hole being formed on the front face.
- the front panels on the base member are detachable from the air-conditioner main body whilst remaining connected to each other.
- Another example is disclosed in Japanese laid open patent application no. 2007-71532 which provides an air-conditioning indoor unit which comprises a first support member provided with a first slit and a third slit, a second support member provided with a first support pawl and a second support pawl, and a movement mechanism having a drive motor for moving the first support member.
- a front surface panel (equivalent to the panel) is made to assume the desired orientation of a second open state by driving the drive motor to move the first support member relative to the second support member. After the panel has been made to assume the desired orientation, a load is imposed on the motor in order to make the panel maintain this orientation.
- the load imposed on the motor when the second sliding member is positioned in a second groove end part which is an end part of the second groove on the side including the second higher curved part is less than the load imposed on the motor when the second sliding member is positioned in the first end part of the second lower curved part. Therefore, in a case in which the panel assumes the desired orientation when the second sliding member is positioned in the second groove end part of the second groove, for example, the load imposed on the motor can be reduced in comparison with a case in which the panel assumes the desired orientation when the second sliding member is positioned in the first end part of the second lower curved part of the second groove.
- the load imposed on the motor can thereby be reduced.
- the second lower curved part only has to have a smaller curvature than the second higher curved part. Therefore, the first lower curved part and the second lower curved part may have linear shapes, for example, without being curved.
- An air-conditioning indoor unit comprises a first member, a second member, a drive member, a motor, an indoor unit main body, and a panel.
- the first member has a first groove and a second groove.

- the motor drives the drive member.
- the indoor unit main body is connected with the first member.
- the panel is connected with the second member. The panel varies an orientation relative to the indoor unit main body due to the second member moving relative to the first member.
- the drive member contacts the second member.
- the second member rotatably moves about the first sliding member as a rotational fulcrum when the second sliding member moves from the second lower curved part to the second higher curved part.
- a load imposed on the motor when the second sliding member is positioned in a second groove end part which is an end part of the second groove on the side including the second higher curved part is less than a load imposed on the motor when the second sliding member is positioned in the first end part of the second lower curved part.
- the load imposed on the motor when the second sliding member is positioned in a second groove end part which is an end part of the second groove on the side including the second higher curved part is less than the load imposed on the motor when the second sliding member is positioned in the first end part of the second lower curved part. Therefore, in a case in which the panel assumes the desired orientation when the second sliding member is positioned in the second groove end part of the second groove, for example, the load imposed on the motor can be reduced in comparison with a case in which the panel assumes the desired orientation when the second sliding member is positioned in the first end part of the second lower curved part of the second groove.
- the load imposed on the motor can thereby be reduced.
- the second lower curved part only has to have a smaller curvature than the second higher curved part. Therefore, the first lower curved part and the second lower curved part may have linear shapes, for example, without being curved.

- the flap 25 and the casing floor surface 14 are disposed adjacent to each other in the forward-backward direction. Consequently, when the flap 25 has closed the second open part 19b, the joint between the flap 25 and the casing floor surface 14 can be made to not stand out when the indoor unit 1 is seen from below.
- FIG. 9(a) is a side view of the indoor unit when operation has stopped.

- the side surface panel parts 32, 32 have substantially the same shapes as the second curved parts 23, 23 of the main body side surface parts 21, 21. Therefore, when the side surface panel parts 32, 32 and the side surface cosmetic panels 24, 24 are disposed adjacent to each other in the forward-backward direction (when the movable panel 30 assumes the hereinafter-described operation-stopped state), slightly convex curved surfaces are configured by the side surface panel parts 32, 32 and the side surface cosmetic panels 24, 24.

- the positions of the first connecting parts 33, 33 and the second connecting parts 34, 34 are moved along with the movement of the panel support arms 55, 55. Therefore, the movable panel 30 is moved either from the operation-stopped position shown in FIG. 9(a) to the operating position shown in FIG. 9(b) , or from the operating position shown in FIG. 9(b) to the operation-stopped position shown in FIG. 9(a) .

- the top end of the linear part 59a of the second sliding opening 59 of the panel support arm 55 and the second support member 53b of the stationary part 53 draw near each other
- the roller 56 of the panel support arm 55 and the bottom end of the guide wall part 51ba of the stationary part 53 draw near each other, as shown in FIG. 12 .
- the first connecting parts 33, 33 are disposed in the position P1 shown in FIG. 11 .
- the panel support arm 55 moves in a direction such that the bottom end of the first sliding opening 58 of the panel support arm 55 and the first support member 53a of the stationary part 53 draw near each other, the bottom end of the linear part 59a of the second sliding opening 59 of the panel support arm 55 and the second support member 53b of the stationary part 53 draw near each other, and the roller 56 of the panel support arm 55 and the top end of the guide wall part 51ba of the stationary part 53 draw near each other, as shown in FIG. 13 .
- the first sliding opening 58 slides relative to the first support member 53a
- the linear part 59a of the second sliding opening 59 slides relative to the second support member 53b.
- the panel support arm 55 moves parallel, diagonally forward and upward. Consequently, the movable panel 30 moves diagonally forward and upward as shown in FIG. 11 .
- the first connecting parts 33, 33 are moved diagonally forward and upward from the position P1 shown in FIG. 11 .
- the panel support arm 55 When the panel support arm 55 is moved to a position where the bottom end of the linear part 59a of the second sliding opening 59 and the second support member 53b draw near each other, the panel support arm 55 moves so that the curved part 59b of the second sliding opening 59 is interlocked with the second support member 53b and the roller 56 is interlocked with the concave part 51bb. Therefore, the panel support arm 55 rotatably moves about the first support member 53a as a fulcrum. The movable panel 30 thereby rotatably moves so as to lean forward as shown in FIG. 11 . At this time, the first connecting parts 33, 33 are moved from the position P2 shown in FIG. 11 to the forward and downward tilted position P3.
- the front surface panel part 31 and the side surface panel parts 32, 32 are formed continuous with each other. Therefore, when the movable panel 30 assumes the operation-stopped state, the main body 20 can be covered continuously from the front to the sides. Consequently, when the indoor unit 1 is viewed at an angle while the movable panel 30 is assuming the operation-stopped state, the joint between the movable panel 30 and the main body 20 can be made to not stand out.
- the design (appearance) can thereby be improved.
- the side surface panel parts 32, 32 are positioned to the sides of the panel support arm 55. Therefore, the quantity of air drawn into the front surface intake port that reaches the drive components can be reduced. Consequently, the adhesion of dust to the panel support arm 55 during operation can be suppressed.
- the panel support arm 55 is mostly covered by the side surface panel parts 32, 32 as seen in a side view. Therefore, the design during operation can be improved.
- the panel support arm 55 when the panel support arm 55 is in the second state, the panel support arm 55 is positioned such that the curved part 59b of the second sliding opening 59 is interlocked with the second support member 53b and the roller 56 is interlocked with the concave part 51bb. Therefore, the risk of the state of the panel support arm 55 switching to the first state can be reduced. Consequently, it is possible to reduce the load on the motor 54, and to make it easier for the movable panel 30 connected with the panel support arm 55 to maintain the operating state.

- a second lower curved part 169a which is a space in the second guide channel 169 and an area in the top part of the second guide channel 169, has an arcuate shape slightly curved into a convex shape.
- the second lower curved part 169a and the first lower curved part 168a have the same arcuate center in the same virtual plane. Therefore, the second lower curved part 169a in the second guide channel 169 is an area having the same arcuate center but a different radius of curvature in the same virtual plane as the first lower curved part 168a.
- a bent part 169b which is a space in the second guide channel 169 and an area in the bottom part of the second guide channel 169, has a greater curvature than the second lower curved part 169a. Therefore, the bent part 169b has an arcuate shape curved into a more convex shape than the second lower curved part 169a.
- the bottom part of the second lower curved part 169a and the top part of the bent part 169b are continuous. Focusing only on the shapes of the first guide channel 168 and the second guide channel 169 formed in the arm 166, the first guide channel 168 has a substantial I shape, and the second guide channel 169 has a substantial J shape.

- the first gear 155 is disposed in the top part of the base part 163a, and the base part 163a rotatably supports the first gear 155.
- the guide part 165 stands upright from the rear-side end part of the base part 163a.
- the guide part 165 has the guide wall part 165a and a curved part 165b.
- the guide wall part 165a constitutes the portion of the guide part 165 other than the curved part 165b, and extends downward from the bottom end of the curved part 165b.
- the guide wall part 165a has an arcuate shape curved slightly into a convex shape.
- the guide wall part 165a, the first lower curved part 168a, and the second lower curved part 169a have the same arcuate center in the same virtual plane. Therefore, the guide wall part 165a in the guide part 165 is an area that has the same arcuate center but a different radius of curvature from the first lower curved part 168a and the second lower curved part 169a in the same virtual plane.
- the curved part 165b constitutes the top end part of the guide part 165.
- the curved part 165b also has a greater curvature than the guide wall part 165a. Therefore, the curved part 165b has an arcuate shape curved into a shape more convex than the guide wall part 165a.
- the curved part 165b has a shape curved along the external peripheral surface of the roller 167 of the first member 162, and the sliding movement of the roller 167 can be restricted by positioning the roller 167 in the curved part 165b.

- the first sliding member 164a is disposed in the top part of the base part 163a. Furthermore, the first sliding member 164a is inserted through the first guide channel 168 so as to slide against the first part 166a.
- the first sliding member 164a interlocks with the first part 166a so that the first member 162 is allowed to move in the forward-backward direction but is restricted from moving in the right direction. Thus, by interlocking with the first part 166a, the first sliding member 164a supports the first member 162.
- the second sliding member 164b which has a substantially cylindrical shape, is provided to the base part 163a so as to protrude outward from the surface of the base part 163a.

- the first gear 155 and the second gear 156 are rotated by the driving of the motor 152, via the drive gear 154. Due to the rotating of the first gear 155, the rack 166g meshed with the first gear 155 is driven, and the first member 162 moves relative to the second member 161. At this time, the positions of the endpoints 166c, 166d, 166e of the arm 166 move respectively along the first guide channel 168, the second guide channel 169, and the guide wall part 165a. Therefore, the trajectories followed by the endpoints 166c, 166d, 166e of the arm 166 are slightly curved into convex shapes.
- a rack 176g meshed with the second gear 156 is driven, and a first member 172 moves relative to a second member 171.
- the positions of endpoints 176c, 176d, 176e of an arm 176 move respectively along a first guide channel 178, a second guide channel 179, and a guide wall part 175a. Therefore, the trajectories followed by the endpoints 176c, 176d, 176e of the arm 176 are slightly curved into convex shapes.
- the drive mechanism 150 excluding the transmission shaft is accommodated in the accommodating spaces S, S formed between the casing side surfaces 115, 115 and the main body side surface parts 121, 121.

- the first member 172 assumes the first state as shown in FIG. 28 .
- the first member 172 is disposed relative to the second member 171 so that a first sliding member 174a is positioned in a top end part 178x of the first guide channel 178, i.e., a top end part 178ax of a first lower curved part 178a, a second sliding member 174b is positioned in a top end part 179x of the second guide channel 179, i.e., a top end part 179ax of a second lower curved part 179a, and a roller 177 is positioned in a bottom end part 175aa of the guide wall part 175a.
- the first member 162 is disposed relative to the second member 161 so that the first sliding member 164a is positioned in a top end part 168x of the first guide channel 168, i.e., a top end part 168ax of the first lower curved part 168a, the second sliding member 164b is positioned in a top end part 169x of the second guide channel 169, i.e., a top end part 169ax of the second lower curved part 169a, and the roller 167 is positioned in a bottom end part 165aa of the guide wall part 165a.
- the first connecting parts 133, 133 are thereby disposed in the position P1 shown in FIG. 27 .

- the first member 162 moves relative to the second member 161 in a direction such that a bottom end part 168y of the first guide channel 168 draws near the first sliding member 164a, a bottom end part 169ay of the second lower curved part 169a of the second guide channel 169 draws near the second sliding member 164b, and the roller 167 draws near the top end part of the guide wall part 165a.
- the portions in the first parts 166a, 176a that define the first lower curved parts 168a, 178a slide relative to the first sliding members 164a, 174a
- the portions in the second parts 166b, 176b that define the second lower curved parts 169a, 179a slide relative to the second sliding members 164b, 174b
- the rollers 167, 177 slide relative to the guide wall parts 165a, 175a. Therefore, the arms 166, 176 slidably move diagonally forward and upward along the first lower curved parts 168a, 178a, the second lower curved parts 169a, 179a, and the guide wall parts 165a, 175a.
- the first members 162, 172 rotate by predetermined angles relative to the second members 161, 171 about the first sliding members 164a, 174a as rotational fulcra.
- the first sliding member 164a is positioned in proximity to the bottom end parts 168y, 178y of the first guide channels 168, 178.
- the first members 162, 172 then move relative to the second members 161, 171 so that the first sliding members 164a, 174a are positioned in the bottom end parts 168y, 178y of the first guide channels 168, 178, the second sliding members 164b, 174b are positioned in bottom end parts 169y, 179y of the second guide channels 169, 179, i.e., the bottom end parts 169by, 179by of the bent parts 169b, 179b, and the rollers 167, 177 are positioned in the curved parts 165b, 175b.
- the portions in the first parts 166a, 176a that define the bottom end parts 168y, 178y of the first guide channels 168, 178 are interlocked with the first sliding member 174a
- the portions in the second parts 166b, 176b that define the bottom end parts 169y, 179y of the second guide channels 169, 179, i.e., the bottom end parts 169by, 179by of the bent parts 169b, 179b are interlocked with the second sliding members 164b, 174b
- the rollers 167, 177 are interlocked with the curved parts 165b, 175b.
- the first members 162, 172 thereby assume the second state as shown in FIGS. 22 and 30 .
- the first connecting parts 133, 133 move to the position P3 diagonally forward and downward from the position P2 shown in FIG. 25 . Consequently, the movable panel 130 moves diagonally forward and downward relative to the main body 120, as shown in FIG. 27 .
- the orientation of the movable panel 130 thereby switches from the operation-stopped orientation to the operating orientation. Since the bottom end parts 169by, 179by of the bent parts 169b, 179b and the curved parts 165b, 175b have large curvatures, the second sliding members 164b, 174b and the rollers 167, 177 have readily interlocking structures.
- the second sliding members 164b, 174b being positioned in the bottom end parts 169by, 179by of the bent parts 169b, 179b and the rollers 167, 177 being positioned in the curved parts 165b, 175b, the second sliding members 164b, 174b do not readily move from the bent parts 169b, 179b to the second lower curved parts 169a, 179a, and the rollers 167, 177 do not readily move from the curved parts 165b, 175b to the guide wall parts 165a, 175a.
- the motor 152 when the movable panel 130 assumes the operating orientation, the motor 152 is driven and a load is therefore imposed on the motor 152.
- the motor 152 when the movable panel 130 assumes the operation-stopped orientation, the motor 152 is not driven and a load is therefore not imposed on the motor 152.
- the first members 162, 172 move relative to the second members 161, 171.

- support of the movable panel 130 and the first members 162, 172 can be divided among the second sliding members 164b, 174b and the first gear 155.
- the bottom end part of the first guide channel bends forward, and the first sliding member interlocks with the portion that defines the bottom end part of the first guide channel, for example; there is greater distance from the portions where the first gear 155 and the second gear 156 contact the arms 166, 176 and support the arms 166, 176 to the second sliding members 164b, 174b which are sliding members supporting the arms, and the load imposed on the motor 152 in order to maintain the orientation of the movable panel 130 can therefore be reduced.
- the load imposed on the motor 152 can also be reduced in comparison with a case in which the arms 166, 176 are supported by only the first gear 155 and the second gear 156.
- the load imposed on the motor 152 can be reduced in comparison with a case in which the second sliding members 164b, 174b are positioned in the bottom end part 179y of the second lower curved part 179a of the second guide channel 179, for example, before the second sliding members 164b, 174b are positioned in the bottom end parts 169by, 179by of the bent parts 169b, 179b.
- the center of gravity of the movable panel 130 is positioned farther forward from the main body 120 than the positions of the second sliding members 164b, 174b.
- the first members 162, 172 rotate relative to the second members 161, 171 about the first sliding members 164a, 174a as rotational fulcra, the first sliding members 164a, 174a being positioned in proximity to the motor 152 and the first gear 155 or the second gear 156, the load imposed on the motor 152 when the first members 162, 172 rotate can be reduced in comparison with a case in which the first members rotate relative to the second members about the second sliding members as rotational fulcra, for example.
- the first members 162, 172 are disposed relative to the second members 161, 171 so that the first sliding members 164a, 174a are positioned in the top end parts 168x, 178x of the first guide channels 168, 178, the second sliding members 164b, 174b are positioned in the top end parts 169x, 179x of the second guide channels 169, 179, and the rollers 167, 177 are positioned in the bottom end parts 165aa, 175aa of the guide wall parts 165a, 175a.
- the first sliding members 164a, 174a being positioned in the top end parts 168x, 178x of the first guide channels 168, 178, the first sliding members 164a, 174a interlock with the first parts 166a, 176a that define the top end parts 168x, 178x of the first guide channels 168, 178, and the movement of the arms 166, 176 in the direction of gravity is restricted.
- the second sliding members 164b, 174b being positioned in the top end parts 169x, 179x of the second guide channels 169, 179, the second sliding members 164b, 174b interlock with the second parts 166b, 176b that define the top end parts 169x, 179x of the second guide channels 169, 179, and the movement of the arms 166, 176 in the direction of gravity is restricted.
- the movement in the direction of gravity of the movable panel 130 connected with the first members 162, 172 is thereby restricted. Consequently, by driving the motor 152 and rotating the first gear 155 and the second gear 156, the movement of the movable panel 130 in the direction of gravity can be restricted even if the arms 166, 176 are not supported.
- the movable panel can thereby be made to assume an orientation that does not impose a load on the motor 152.
- the movable panel 130 is disposed on the front-surface side of the main body 120.
- the movable panel 130 assumes the operating orientation
- the movable panel 130 is disposed at a tilt relative to the main body 120, whereby the second intake port 118b formed in the casing forward surface 113 of the main body 120 can be opened up.
- the movable panel 130 assumes the operation-stopped orientation
- the movable panel 130 is disposed substantially parallel to the main body 120, whereby the second intake port 118b formed in the casing forward surface 113 of the main body 120 and the first open part 119a of the discharge port 119 can be blocked.
- the first members 162, 172 have the rollers 167, 177.
- the second members 161, 171 have the guide parts 165, 175.
- the rollers 167, 177 are positioned in the curved parts 165b, 175b of the guide parts 165, 175, the second sliding members 164b, 174b are positioned in the bottom end parts 169by, 179by of the bent parts 169b, 179b.
- the arms 166, 176 can be supported by the first gear 155, the second gear 156, the second sliding members 164b, 174b, and the curved parts 165b, 175b.
- the load imposed on the motor 152 when the movable panel 130 is made to assume the operating orientation as the desired orientation can thereby be further reduced.
- first guide channel 168 and the second lower curved parts 169a of the second guide channel 169 formed in the arm 166 have arcuate shapes slightly curved into convex shapes.
- the second lower curved parts of the first guide channel and the second guide channel need not have arcuate shapes.
- the first guide channel may have a linear shape
- the second lower curved part of the second guide channel may be formed in the arm so as to have a linear shape parallel to the first guide channel.
- the first gear 155 and the second gear 156 are driven by a single motor 152.

- first guide channel 168 and the second guide channel 169 are slit-shaped openings passing through both surfaces of the arm 166.
- the first guide channel and the second guide channel need not be openings.
- the first guide channel and the second guide channel may be groove-shaped concavities provided in the arm.

Therefore, due to the first members 162, 172 moving relative to the second members 161, 171, the movable panel 130 connected with the first members 162, 172 moves relative to the main body 120 to which the second members 161, 171 are fixed.
- the orientation of the movable panel 130 relative to the main body 120 is thereby varied.
- the drive part may be a mechanism for moving second members 261, 271, which have a first sliding member and a second sliding member, relative to first members 262, 272, in which a first guide channel and a second guide channel are formed.
- the second guide channel is formed in the first members 262, 272 so as to have a shape with a bent top part, i.e., so that a top part of a second lower curved part and a bottom part of a bent part are continuous.

- the second members 261, 271 are moved relative to the first members 262, 272 by the drive part, whereby the movable panel 130 fixed to the second members 261, 271 moves integrally with the second members 261, 271, and the movable panel 130 can therefore be moved relative to the main body 120.
- the orientation of the movable panel 130 relative to the main body 120 can thereby be varied.
- the second members 261, 271 are restricted from moving due to the second sliding member being interlocked with the portion that defines the top end part of the curved part. Therefore, compared with a case in which the top end part of the second guide channel is not bent, the top end part of the first guide channel is bent forward, and the first sliding member is interlocked with the portion that defines the top end part of the first guide channel, for example; there is a greater distance from the portion where the first gear and the second gear contact the second members 261, 271 and support the second members 261, 271 to the portion defining the bent part of the second guide channel supporting the second members 261, 271, and the load imposed on the motor in order to maintain the orientation of the movable panel 130 can be reduced.

Description
- The present invention relates to an air conditioner.
- In the past, there have been air conditioners which comprise a main body in which an intake port and a discharge port are formed in a front surface. For example, the air conditioner disclosed in Patent Literature 1 (Japanese Utility Model Application No.
4-20923 - In the air conditioner of Patent Literature 1, only the front surface of the conditioner main body is covered by the panel. Therefore, when the conditioner main body is viewed at an angle while the panel is in the close position, there is a possibility that the joint between the conditioner main body and the panel will stand out, which is not good for the design.
- In view of this, an object of the present invention is to provide an indoor unit of an air conditioner in which the design can be improved.
- An indoor unit of an air conditioner according to a first aspect comprises a main body and a movable panel. A front surface intake port and a front surface discharge port are formed in a front surface of the main body. The movable panel has a front surface panel part and a side surface panel part. The front surface panel part is positioned in front of the main body. The side surface panel part is formed continuing rearward from both ends of the front surface panel part. When operation has stopped, the movable panel assumes an operation-stopped state of being disposed so that the front surface panel part covers the front surface intake port and the front surface discharge port.
- In the indoor unit of an air conditioner according to the first aspect, the side surface panel part is formed continuing rearward from both ends of the front surface panel part. Therefore, when the movable panel assumes the operation-stopped state, the main body can be covered from the front to the sides of the main body. Consequently, when the main body in which the movable panel has assumed the operation-stopped state is viewed at an angle, it is easier to make the joint between the movable panel and the main body not stand out than in a case of a configuration in which the movable panel covers only the front of the main body, for example.
- The design can thereby be improved.
- An indoor unit of an air conditioner according to a second aspect is the indoor unit of an air conditioner according to the first aspect, further comprising a drive mechanism. The drive mechanism has a drive component for moving the movable panel. The movable panel assumes an operating state of opening up the front surface intake port and the front surface discharge port by moving diagonally upward from the operation-stopped state. When the movable panel has assumed the operating state, the side surface panel part is positioned to the side of the drive component.
- In the indoor unit of an air conditioner according to the second aspect, when the movable panel assumes the operating state, the side surface panel part is positioned to the side of the drive component. Therefore, the quantity of air drawn in from the side can be reduced in comparison with a case in which the side surface panel part is not positioned to the side of the drive component, for example.
- The possibility that dust will adhere to the drive component during operation can thereby be reduced.
- An indoor unit of an air conditioner according to a third aspect is the indoor unit of an air conditioner according to the second aspect, wherein the drive component includes a panel support arm. The panel support arm is connected to the movable panel. The panel support arm can be switched between a first state of being accommodated in the main body and a second state of being separated from the main body. Furthermore, the panel support arm is in the second state when the movable panel has assumed the operating state. When the movable panel has assumed the operating state, the side surface panel part is disposed so as to cover the panel support arm being in the second state in a side view.
- In the indoor unit of an air conditioner according to the third aspect, when the movable panel assumes the operating state, the panel side surface part is disposed so as to cover the panel support arm separated from the main body in a side view. Therefore, the design during operation can be improved.
- An air-conditioning indoor unit according to a fourth aspect comprises a first member, a second member, a drive member, a motor, an indoor unit main body, and a panel. The first member has a first groove and a second groove. The first groove includes a first lower curved part. The second groove includes a second lower curved part and a second higher curved part. The second lower curved part is in a position separated from the first lower curved part. The second higher curved part extends from a first end part which is an end part of the second lower curved part. The second higher curved part also has a greater curvature than the second lower curved part. The second member has a first sliding member and a second sliding member. The first sliding member moves along the first groove. The second sliding member moves along the second groove. The drive member moves the first member relative to the second member so that the first sliding member slides against the first groove and the second sliding member slides against the second groove. The motor drives the drive member. The indoor unit main body is connected to the second member. The panel is connected with the first member. The panel varies an orientation relative to the indoor unit main body due to the first member moving relative to the second member. Furthermore, the drive member contacts the first member. The first member rotatably moves about the first sliding member as a rotational fulcrum when the second sliding member moves from the second lower curved part to the second higher curved part. A load imposed on the motor when the second sliding member is positioned in a second groove end part which is an end part of the second groove on the side including the second higher curved part is less than a load imposed on the motor when the second sliding member is positioned in the first end part of the second lower curved part.
- In the past, there have been air-conditioning indoor units which comprise a panel as part of the contour of the air-conditioning indoor unit, and a movement mechanism for moving the panel in order to cause the panel to assume the desired orientation. For example,
JP 2006 064361 2007-71532 - In view of this, in the air-conditioning indoor unit according to the fourth aspect, the load imposed on the motor when the second sliding member is positioned in a second groove end part which is an end part of the second groove on the side including the second higher curved part is less than the load imposed on the motor when the second sliding member is positioned in the first end part of the second lower curved part. Therefore, in a case in which the panel assumes the desired orientation when the second sliding member is positioned in the second groove end part of the second groove, for example, the load imposed on the motor can be reduced in comparison with a case in which the panel assumes the desired orientation when the second sliding member is positioned in the first end part of the second lower curved part of the second groove.
- The load imposed on the motor can thereby be reduced.
- The second lower curved part only has to have a smaller curvature than the second higher curved part. Therefore, the first lower curved part and the second lower curved part may have linear shapes, for example, without being curved.
- An air-conditioning indoor unit according to a fifth aspect comprises a first member, a second member, a drive member, a motor, an indoor unit main body, and a panel.

The second lower curved part is in a position separated from the first lower curved part. The second higher curved part extends from a first end part which is an end part of the second lower curved part. The second higher curved part also has a greater curvature than the second lower curved part. The second member has a first sliding member and a second sliding member. The first sliding member moves along the first groove. The second sliding member moves along the second groove. The drive member moves the second member relative to the first member so that the first sliding member slides against the first groove and the second sliding member slides against the second groove. The motor drives the drive member. The indoor unit main body is connected with the first member. The panel is connected with the second member. The panel varies an orientation relative to the indoor unit main body due to the second member moving relative to the first member. The drive member contacts the second member. The second member rotatably moves about the first sliding member as a rotational fulcrum when the second sliding member moves from the second lower curved part to the second higher curved part. A load imposed on the motor when the second sliding member is positioned in a second groove end part which is an end part of the second groove on the side including the second higher curved part is less than a load imposed on the motor when the second sliding member is positioned in the first end part of the second lower curved part.
- In the air-conditioning indoor unit according to the fifth aspect, the load imposed on the motor when the second sliding member is positioned in a second groove end part which is an end part of the second groove on the side including the second higher curved part is less than the load imposed on the motor when the second sliding member is positioned in the first end part of the second lower curved part. Therefore, in a case in which the panel assumes the desired orientation when the second sliding member is positioned in the second groove end part of the second groove, for example, the load imposed on the motor can be reduced in comparison with a case in which the panel assumes the desired orientation when the second sliding member is positioned in the first end part of the second lower curved part of the second groove.
- The load imposed on the motor can thereby be reduced.
- The second lower curved part only has to have a smaller curvature than the second higher curved part. Therefore, the first lower curved part and the second lower curved part may have linear shapes, for example, without being curved.

Thestationary part 53 has a stationary platemain body 51, a drivengear 52, afirst support member 53a, and asecond support member 53b. - The stationary plate
main body 51 includes a plate-shapedmain body part 51a having a substantially flat surface, and aguide part 51b standing upright from the rear-side end part of themain body part 51a. Themain body part 51a has a substantially triangular shape (seeFIG. 10 ). Theguide part 51b has a guide wall part 51ba and a concave part 51bb. The concave part 51bb, which constitutes the top end part of theguide part 51b, has a shape curved along the external peripheral surface of aroller 56, described hereinafter. The guide wall part 51ba constitutes the rest of theguide part 51b other than the concave part 51bb, and extends in a substantially straight line from the bottom end of the concave part 51bb. The drivengear 52 is rotatably supported on themain body part 51a so as to protrude outward from the surface of themain body part 51a. Thefirst support member 53a, which has a substantially cylindrical shape, is provided to themain body part 51a so as to protrude outward from the surface of themain body part 51a. Thesecond support member 53b, which has a substantially cylindrical shape, is provided to themain body part 51a so as to protrude outward from the surface of themain body part 51a. Thesecond support member 53b is disposed below thefirst support member 53a. - The
panel support arm 55 is a plate-shaped member having substantially the same shape as themain body part 51a of thestationary part 53, and is connected with the inner surface of themovable panel 30. Specifically, the proximity of anend point 55a positioned at the top part of thepanel support arm 55 and the first connectingpart 33 of themovable panel 30 are connected, and the proximity of anend point 55b positioned at the forward bottom part of thepanel support arm 55 and the second connectingpart 34 of themovable panel 30 are connected. Theroller 56 is disposed in proximity to anend point 55c positioned at the rearward bottom part of thepanel support arm 55. Theroller 56 is rotatably supported on thepanel support arm 55. In proximity to anedge 55d joining theend point 55a andend point 55c of thepanel support arm 55, arack 57 which meshes with the drivengear 52 is provided substantially parallel with theedge 55d. Furthermore, a first slidingopening 58 and a second slidingopening 59 are formed in thepanel support arm 55. The first slidingopening 58 and the second slidingopening 59 are slit-shaped openings, each passing through a surface of thepanel support arm 55. The first slidingopening 58 and the second slidingopening 59 have shapes inclined so that their top parts are positioned farther forward than their bottom parts. Specifically, the first slidingopening 58 is formed into a substantially straight line so as to be substantially parallel with theedge 55d of thepanel support arm 55. The second slidingopening 59 has alinear part 59a extending substantially parallel with the first slidingopening 58, and acurved part 59b formed continuing from the bottom end of thelinear part 59a. Thecurved part 59b curves diagonally forward and downward from the bottom end of thelinear part 59a. Focusing only on the shapes of the first slidingopening 58 and the second slidingopening 59, the first slidingopening 58 has a substantial I shape, and the second slidingopening 59 has a substantial J shape. - The
first support member 53a is inserted into the first slidingopening 58. Consequently, thefirst support member 53a interlocks with the first slidingopening 58 and supports thepanel support arm 55. Furthermore, thesecond support member 53b is inserted into the second slidingopening 59. Consequently, thesecond support member 53b interlocks with the second slidingopening 59 and supports thepanel support arm 55. - With such a configuration, in the
drive mechanism 50, the driving of themotor 54 causes theracks drive gear 54b and the driven gears 52, 52, whereby the positions of theend points panel support arms parts parts panel support arms movable panel 30 is moved either from the operation-stopped position shown inFIG. 9(a) to the operating position shown inFIG. 9(b) , or from the operating position shown inFIG. 9(b) to the operation-stopped position shown inFIG. 9(a) . The state of themovable panel 30 is thereby switched either from the operation-stopped state to the operating state, or from the operating state to the operation-stopped state. When themovable panel 30 is in the operation-stopped state, thepanel support arms main body 20. Furthermore, when themovable panel 30 is in the operating state, thepanel support arms main body 20. - In the present embodiment, the
drive mechanism 50 excluding the power transmission shaft is accommodated in the accommodating spaces S formed between the casing side surfaces 15, 15 and the main bodyside surface parts 21, 21 (seeFIG. 8 ). Specifically, a drive mechanismmain body 50b, themotor 54, and adrive gear 54b are accommodated in the right-side accommodating space S. Astationary part 53 is disposed in front (to the right) of the right-sidecasing side surface 15, apanel support arm 55 is disposed in front (to the right) of thestationary part 53, and themotor 54 is disposed in front (to the right) of thepanel support arm 55. A drive mechanismmain body 50b and adrive gear 54b are accommodated in the left-side accommodating space S. Astationary part 53 is disposed in front (to the left) of the left-sidecasing side surface 15, and apanel support arm 55 is disposed in front (to the left) of thestationary part 53. - In the present embodiment, when the
panel support arms 55 are in the second state as shown inFIG. 9(b) , the sidesurface panel parts panel support arms 55. Therefore, thepanel support arms 55 in the second state are mostly covered by the sidesurface panel parts -
FIG. 11 is a schematic view showing the trajectory of a first connectingpart 33 of themovable panel 30.FIG. 12 is a side view of the drive mechanismmain body 50b disposed on the left-side end part of themain body 20, and is a schematic view showing a case in which thepanel support arm 55 is in the first state.FIG. 13 is a side view of the drive mechanismmain body 50b disposed on the left-side end part of themain body 20, and is a schematic view showing a case in which thepanel support arm 55 transitions from the first state to the second state.FIG. 14 is a side view of the drive mechanismmain body 50b disposed on the left-side end part of themain body 20, and is a schematic view showing a case in which thepanel support arm 55 is in the second state. InFIG. 11 , the trajectory of the first connectingpart 33 is shown by the single-dashed line. - Next, the action of the
movable panel 30 and the trajectories of the first connectingparts movable panel 30 switches are described usingFIGS. 11 ,12 ,13 , and14 . - When the state of the
movable panel 30 is the operation-stopped state, the top end of the first slidingopening 58 of thepanel support arm 55 and thefirst support member 53a of thestationary part 53 draw near each other, the top end of thelinear part 59a of the second slidingopening 59 of thepanel support arm 55 and thesecond support member 53b of thestationary part 53 draw near each other, and theroller 56 of thepanel support arm 55 and the bottom end of the guide wall part 51ba of thestationary part 53 draw near each other, as shown inFIG. 12 . At this time, the first connectingparts FIG. 11 . - When the state of the
movable panel 30 switches from the operation-stopped state to the operating state, thepanel support arm 55 moves in a direction such that the bottom end of the first slidingopening 58 of thepanel support arm 55 and thefirst support member 53a of thestationary part 53 draw near each other, the bottom end of thelinear part 59a of the second slidingopening 59 of thepanel support arm 55 and thesecond support member 53b of thestationary part 53 draw near each other, and theroller 56 of thepanel support arm 55 and the top end of the guide wall part 51ba of thestationary part 53 draw near each other, as shown inFIG. 13 . At this time, the first slidingopening 58 slides relative to thefirst support member 53a, and thelinear part 59a of the second slidingopening 59 slides relative to thesecond support member 53b. Therefore, thepanel support arm 55 moves parallel, diagonally forward and upward. Consequently, themovable panel 30 moves diagonally forward and upward as shown inFIG. 11 . At this time, the first connectingparts FIG. 11 . - When the
panel support arm 55 is moved to a position where the bottom end of thelinear part 59a of the second slidingopening 59 and thesecond support member 53b draw near each other, thepanel support arm 55 moves so that thecurved part 59b of the second slidingopening 59 is interlocked with thesecond support member 53b and theroller 56 is interlocked with the concave part 51bb. Therefore, thepanel support arm 55 rotatably moves about thefirst support member 53a as a fulcrum. Themovable panel 30 thereby rotatably moves so as to lean forward as shown inFIG. 11 . At this time, the first connectingparts FIG. 11 to the forward and downward tilted position P3. - In the embodiment described above, the front
surface panel part 31 and the sidesurface panel parts movable panel 30 assumes the operation-stopped state, themain body 20 can be covered continuously from the front to the sides. Consequently, when the indoor unit 1 is viewed at an angle while themovable panel 30 is assuming the operation-stopped state, the joint between themovable panel 30 and themain body 20 can be made to not stand out. - The design (appearance) can thereby be improved.
- In the embodiment described above, when the
panel support arm 55 is in the second state, the sidesurface panel parts panel support arm 55. Therefore, the quantity of air drawn into the front surface intake port that reaches the drive components can be reduced. Consequently, the adhesion of dust to thepanel support arm 55 during operation can be suppressed. In the second state, thepanel support arm 55 is mostly covered by the sidesurface panel parts - In the embodiment described above, when the
panel support arm 55 is in the second state, thepanel support arm 55 is positioned such that thecurved part 59b of the second slidingopening 59 is interlocked with thesecond support member 53b and theroller 56 is interlocked with the concave part 51bb. Therefore, the risk of the state of thepanel support arm 55 switching to the first state can be reduced. Consequently, it is possible to reduce the load on themotor 54, and to make it easier for themovable panel 30 connected with thepanel support arm 55 to maintain the operating state. - An air-conditioning

When themovable panel 130 assumes the operating orientation, themovable panel 130 is moved diagonally forward and upward from its position at the time of the operation-stopped orientation. Therefore, when themovable panel 130 assumes the operating orientation, themovable panel 130 is disposed at a tilt so that atop edge 131a of the frontsurface panel part 131 is farther from the casing forward surface 113 than abottom edge 131b of the frontsurface panel part 131. Consequently, when themovable panel 130 assumes the operating orientation, thesecond intake port 118b provided to the top part of the casing forward surface 113 is opened up. When themovable panel 130 assumes the operating orientation, themovable panel 130 is disposed so that thebottom edge 131b of the frontsurface panel part 131 is positioned above the firstopen part 119a of thedischarge port 119. Therefore, when themovable panel 130 assumes the operating orientation, the firstopen part 119a of thedischarge port 119 is opened up. - In the present embodiment, due to the driving of the
movable panel 130 and theflap 125, thesecond intake port 118b and thedischarge port 119 are blocked when the air-conditioningindoor unit 100 has stopped operating, and thesecond intake port 118b and thedischarge port 119 are opened up during operation. -
FIG. 22 is a side view of thedrive mechanism 150.FIG. 23 is an exploded perspective view of thedrive mechanism 150.FIG. 24 is a side view of afirst member 162.FIG. 25 is a side view of asecond member 161.FIG. 26 is a right-side view of the air-conditioningindoor unit 100. The drawing ofFIG. 26 omits themovable panel 130. - The
drive mechanism 150 is a mechanism for moving themovable panel 130 in order to vary the orientation of themovable panel 130 relative to themain body 120. Thedrive mechanism 150 has primarily adrive part 151 and drive mechanismmain bodies 160, 170 (seeFIGS. 22 and28 ). - The
drive part 151 comprises onemotor 152 and apower transmission part 153. - The
motor 152 is a stepping motor and is disposed in proximity to the right-side end part of themain body 120 as shown inFIG. 18 . Themotor 152 has adrive shaft 152a and adrive gear 154 as shown inFIG. 22 . Thedrive shaft 152a is rotated by the driving of themotor 152. Thedrive gear 154 is attached to thedrive shaft 152a and is rotated by the rotating of thedrive shaft 152a. Themotor 152 is controlled by a controller (not shown) and is rotatably driven. - The
power transmission part 153 is a mechanism for distributing and transmitting the drive force of themotor 152 to the drive mechanismmain bodies power transmission part 153 has a transmission shaft (not shown), afirst gear 155, and a second gear 156 (seeFIG. 28 ). The transmission shaft is disposed so as to extend in the left-right direction. Thefirst gear 155 is attached to the right-side end part of the transmission shaft. Thesecond gear 156 is attached to the left-side end part of the transmission shaft. Furthermore, thefirst gear 155 is disposed so as to mesh with thedrive gear 154, and is rotated by the rotating of thedrive gear 154. The transmission shaft is rotated by the rotating of thefirst gear 155, and thesecond gear 156 is rotated by the rotating of the transmission shaft. Thus, in thepower transmission part 153, power transferred from thedrive gear 154 to thefirst gear 155 can be transferred to thesecond gear 156 via the transmission shaft. - The drive mechanism
main bodies first members second members main bodies main body 160 disposed in the right-side end part of themain body 120 is described, and the drive mechanismmain body 170 disposed in the left-side end part of themain body 120 has symbols in the 170s in place of the symbols in the 160s indicating the parts of the drive mechanismmain body 160, the parts of the 170s not being described. - The
first member 162 has anarm 166 and aroller 167. In the present embodiment, thefirst member 162 is configured integrally from combining a plurality of components including thearm 166, theroller 167, and others, but the first member is not limited to this option and may be configured from a single component. - The
arm 166 is a plate-shaped member having a substantially triangular shape, and is connected with the inner surface of themovable panel 130. Specifically, the proximity of anendpoint 166c positioned at the top of thearm 166 and a first connectingpart 133 of themovable panel 130 are connected, and the proximity of anendpoint 166d positioned in the forward-side bottom part of thearm 166 and a second connectingpart 134 of themovable panel 130 are connected. - An
edge 166f joining theendpoint 166c with anendpoint 166e positioned in the rear-side bottom part of thearm 166 is slightly curved into a convex shape. Furthermore, in proximity to theedge 166f of thearm 166, arack 166g which meshes with thefirst gear 155 is provided along theedge 166f. Thearm 166 has afirst part 166a and asecond part 166b. Thefirst part 166a and thesecond part 166b are disposed so as to be vertically aligned. - A
first guide channel 168 is formed in thefirst part 166a. Thefirst guide channel 168 is a slit-shaped opening passing through both surfaces of thearm 166. Thefirst guide channel 168 is formed in proximity to theedge 166f of thearm 166. Thefirst guide channel 168 is formed in thearm 166 so as to have an arcuate shape slightly curved into a convex shape along theedge 166f of thearm 166. Therefore, a first lowercurved part 168a, which is a space in thefirst guide channel 168, has an arcuate shape slightly curved into a convex shape along theedge 166f of thearm 166. - A
second guide channel 169 is formed in thesecond part 166b. Thesecond guide channel 169 is a slit-shaped opening passing through both surfaces of thearm 166. Thesecond guide channel 169 is disposed in a position separated farther from theedge 166f of thearm 166 than thefirst guide channel 168. Thesecond guide channel 169 is formed in thearm 166 so as to have a portion having an arcuate shape slightly curved into a convex shape similar to thefirst guide channel 168, and a portion curved forward from an end part of the first portion. Therefore, a second lowercurved part 169a, which is a space in thesecond guide channel 169 and an area in the top part of thesecond guide channel 169, has an arcuate shape slightly curved into a convex shape. The second lowercurved part 169a and the first lowercurved part 168a have the same arcuate center in the same virtual plane. Therefore, the second lowercurved part 169a in thesecond guide channel 169 is an area having the same arcuate center but a different radius of curvature in the same virtual plane as the first lowercurved part 168a. Abent part 169b, which is a space in thesecond guide channel 169 and an area in the bottom part of thesecond guide channel 169, has a greater curvature than the second lowercurved part 169a. Therefore, thebent part 169b has an arcuate shape curved into a more convex shape than the second lowercurved part 169a. The bottom part of the second lowercurved part 169a and the top part of thebent part 169b are continuous. Focusing only on the shapes of thefirst guide channel 168 and thesecond guide channel 169 formed in thearm 166, thefirst guide channel 168 has a substantial I shape, and thesecond guide channel 169 has a substantial J shape. - The
roller 167 is disposed in proximity to theendpoint 166e of thearm 166. Theroller 167 is rotatably supported on thearm 166. Furthermore, theroller 167 moves along aguide wall part 165a of aguide part 165, described hereinafter. - The
first member 162 assumes a first state and a second state. When thefirst member 162 assumes the first state, thefirst member 162 is disposed so that theendpoint 166c and theendpoint 166d of thearm 166 are positioned on the same straight line. When thefirst member 162 assumes the second state, thefirst member 162 is disposed so that theendpoint 166c of thearm 166 is positioned farther forward than theendpoint 166d. In the present embodiment, when thefirst member 162 assumes the first state, thefirst member 162 is accommodated in themain body 120. When thefirst member 162 assumes the second state, thefirst member 162 is disposed so that the top part of thearm 166 protrudes from themain body 120. - The
second member 161, which is fixed to the outer side of thecasing side surface 115, movably supports thefirst member 162. Thesecond member 161 has amain body part 163, a first slidingmember 164a, and a second slidingmember 164b. In the present embodiment, thesecond member 161 is configured integrally from a combination of a plurality of components including themain body part 163, the first slidingmember 164a, the second slidingmember 164b, and others, but the second member is not limited as such and may be configured from a single component. Themain body part 163 has abase part 163a and aguide part 165. - The
base part 163a is a plate-shaped member having a substantially flat surface. Thebase part 163a has a shape substantially identical to thearm 166 of the first member 162 (seeFIGS. 24 and25 ). Furthermore, thefirst gear 155 is disposed in the top part of thebase part 163a, and thebase part 163a rotatably supports thefirst gear 155. - The
guide part 165 stands upright from the rear-side end part of thebase part 163a. Theguide part 165 has theguide wall part 165a and a curved part 165b. Theguide wall part 165a constitutes the portion of theguide part 165 other than the curved part 165b, and extends downward from the bottom end of the curved part 165b. Theguide wall part 165a has an arcuate shape curved slightly into a convex shape. Theguide wall part 165a, the first lowercurved part 168a, and the second lowercurved part 169a have the same arcuate center in the same virtual plane. Therefore, theguide wall part 165a in theguide part 165 is an area that has the same arcuate center but a different radius of curvature from the first lowercurved part 168a and the second lowercurved part 169a in the same virtual plane. - The curved part 165b constitutes the top end part of the
guide part 165. The curved part 165b also has a greater curvature than theguide wall part 165a. Therefore, the curved part 165b has an arcuate shape curved into a shape more convex than theguide wall part 165a. Specifically, the curved part 165b has a shape curved along the external peripheral surface of theroller 167 of thefirst member 162, and the sliding movement of theroller 167 can be restricted by positioning theroller 167 in the curved part 165b. - The first sliding
member 164a, which has a substantially cylindrical shape, is provided to thebase part 163a so as to protrude outward from the surface of thebase part 163a. The first slidingmember 164a is disposed in the top part of thebase part 163a. Furthermore, the first slidingmember 164a is inserted through thefirst guide channel 168 so as to slide against thefirst part 166a. The first slidingmember 164a interlocks with thefirst part 166a so that thefirst member 162 is allowed to move in the forward-backward direction but is restricted from moving in the right direction. Thus, by interlocking with thefirst part 166a, the first slidingmember 164a supports thefirst member 162. - The second sliding
member 164b, which has a substantially cylindrical shape, is provided to thebase part 163a so as to protrude outward from the surface of thebase part 163a. The second slidingmember 164b is disposed below the first slidingmember 164a in thebase part 163a. Furthermore, the second slidingmember 164b is inserted through thesecond guide channel 169 so as to slide against thesecond part 166b. The second slidingmember 164b interlocks with thesecond part 166b so that thefirst member 162 is allowed to move in the forward-backward direction but is restricted from moving in the right direction. Thus, by interlocking with thesecond part 166b, the second slidingmember 164b supports thefirst member 162. - With such a configuration, in the
drive mechanism 150, thefirst gear 155 and thesecond gear 156 are rotated by the driving of themotor 152, via thedrive gear 154. Due to the rotating of thefirst gear 155, therack 166g meshed with thefirst gear 155 is driven, and thefirst member 162 moves relative to thesecond member 161. At this time, the positions of theendpoints arm 166 move respectively along thefirst guide channel 168, thesecond guide channel 169, and theguide wall part 165a. Therefore, the trajectories followed by theendpoints arm 166 are slightly curved into convex shapes. Due to the rotating of thesecond gear 156, arack 176g meshed with thesecond gear 156 is driven, and afirst member 172 moves relative to asecond member 171. At this time, the positions ofendpoints arm 176 move respectively along afirst guide channel 178, asecond guide channel 179, and aguide wall part 175a. Therefore, the trajectories followed by theendpoints arm 176 are slightly curved into convex shapes. - In the present embodiment, as described above, the
drive mechanism 150 excluding the transmission shaft is accommodated in the accommodating spaces S, S formed between the casing side surfaces 115, 115 and the main bodyside surface parts main body 160, themotor 152, thedrive gear 154, and thefirst gear 155 are accommodated in the right-side accommodating space S. More specifically, thesecond member 161 is disposed in front (to the right) of thecasing side surface 115, thefirst member 162 is disposed in front (to the right) of thesecond member 161, and themotor 152 is disposed in front (to the right) of thefirst member 162. The drive mechanismmain body 170 and thesecond gear 156 are accommodated in the left-side accommodating space S. Specifically, thesecond member 171 is disposed in front (to the left) of thecasing side surface 115, and thefirst member 172 is disposed in front (to the left) of thesecond member 171. -
FIG. 27 is a schematic view showing the trajectory of the first connectingpart 133 of themovable panel 130.FIG. 28 is a side view of the drive mechanismmain body 170, and is a schematic view showing a case in which thefirst member 172 is in the first state.FIG. 29 is a side view of the drive mechanismmain body 170, and is a schematic view showing a case in which thefirst member 172 is transitioning from the first state to the second state.FIG. 30 is a side view of the drive mechanismmain body 170, and is a schematic view showing a case in which thefirst member 172 is in the second state. InFIG. 27 , the trajectory of the first connectingpart 133 is shown by a single-dash line. - Next,
FIGS. 27 ,28 ,29 , and30 are used to describe the action of themovable panel 130 and the trajectories of the first connectingparts movable panel 130 switches. - When the
movable panel 130 assumes the operation-stopped orientation, thefirst member 172 assumes the first state as shown inFIG. 28 . Specifically, when themovable panel 130 assumes the operation-stopped orientation, thefirst member 172 is disposed relative to thesecond member 171 so that a first slidingmember 174a is positioned in atop end part 178x of thefirst guide channel 178, i.e., a top end part 178ax of a first lowercurved part 178a, a second slidingmember 174b is positioned in atop end part 179x of thesecond guide channel 179, i.e., a top end part 179ax of a second lowercurved part 179a, and aroller 177 is positioned in a bottom end part 175aa of theguide wall part 175a. When themovable panel 130 assumes the operation-stopped orientation, thefirst member 162 is disposed relative to thesecond member 161 so that the first slidingmember 164a is positioned in atop end part 168x of thefirst guide channel 168, i.e., a top end part 168ax of the first lowercurved part 168a, the second slidingmember 164b is positioned in atop end part 169x of thesecond guide channel 169, i.e., a top end part 169ax of the second lowercurved part 169a, and theroller 167 is positioned in a bottom end part 165aa of theguide wall part 165a. The first connectingparts FIG. 27 . - When the orientation of the
movable panel 130 switches from the operation-stopped orientation to the operating orientation, thefirst member 172 moves relative to thesecond member 171 in a direction such that abottom end part 178y of thefirst guide channel 178 draws near the first slidingmember 174a, a bottom end part 179ay of the second lowercurved part 179a of thesecond guide channel 179 draws near the second slidingmember 174b, and theroller 177 draws near the top end part of theguide wall part 175a, as shown inFIG. 29 . When the orientation of themovable panel 130 switches from the operation-stopped orientation to the operating orientation, thefirst member 162 moves relative to thesecond member 161 in a direction such that abottom end part 168y of thefirst guide channel 168 draws near the first slidingmember 164a, a bottom end part 169ay of the second lowercurved part 169a of thesecond guide channel 169 draws near the second slidingmember 164b, and theroller 167 draws near the top end part of theguide wall part 165a. At this time, the portions in thefirst parts curved parts members second parts curved parts members rollers guide wall parts arms curved parts curved parts guide wall parts parts arms FIG. 27 . Consequently, themovable panel 130 slidably moves diagonally forward and upward relative to themain body 120, as shown inFIG. 27 . - When the
first members second members members curved parts bent parts second guide channels first members second members members bent parts rollers guide wall parts curved parts 165b, 175b, thefirst members second members members member 164a is positioned in proximity to thebottom end parts first guide channels first members second members members bottom end parts first guide channels members bottom end parts second guide channels bent parts rollers curved parts 165b, 175b. Thereby, the portions in thefirst parts bottom end parts first guide channels member 174a, the portions in thesecond parts bottom end parts second guide channels bent parts members rollers curved parts 165b, 175b. Thefirst members FIGS. 22 and30 . The first connectingparts FIG. 25 . Consequently, themovable panel 130 moves diagonally forward and downward relative to themain body 120, as shown inFIG. 27 . The orientation of themovable panel 130 thereby switches from the operation-stopped orientation to the operating orientation. Since the bottom end parts 169by, 179by of thebent parts curved parts 165b, 175b have large curvatures, the second slidingmembers rollers members bent parts rollers curved parts 165b, 175b, the second slidingmembers bent parts curved parts rollers curved parts 165b, 175b to theguide wall parts - In the present embodiment, when the
movable panel 130 assumes the operating orientation, themotor 152 is driven and a load is therefore imposed on themotor 152. When themovable panel 130 assumes the operation-stopped orientation, themotor 152 is not driven and a load is therefore not imposed on themotor 152. - In the present embodiment, the
first members second members movable panel 130 is connected with thefirst members second members main body 120. Furthermore, when themovable panel 130 assumes the operating orientation, the second slidingmembers bent parts first members arms movable panel 130 assumes the operating orientation, support of themovable panel 130 and thefirst members members first gear 155. Therefore, in comparison with an arm in which the bottom end part of the second guide channel is not bent, the bottom end part of the first guide channel bends forward, and the first sliding member interlocks with the portion that defines the bottom end part of the first guide channel, for example; there is greater distance from the portions where thefirst gear 155 and thesecond gear 156 contact thearms arms members motor 152 in order to maintain the orientation of themovable panel 130 can therefore be reduced. The load imposed on themotor 152 can also be reduced in comparison with a case in which thearms first gear 155 and thesecond gear 156. When the second slidingmembers bent parts motor 152 can be reduced in comparison with a case in which the second slidingmembers bottom end part 179y of the second lowercurved part 179a of thesecond guide channel 179, for example, before the second slidingmembers bent parts movable panel 130 is positioned farther forward from themain body 120 than the positions of the second slidingmembers - Furthermore, in the present embodiment, since the
first members second members members members motor 152 and thefirst gear 155 or thesecond gear 156, the load imposed on themotor 152 when thefirst members - In the present embodiment, when the
movable panel 130 assumes the operation-stopped orientation, thefirst members second members members top end parts first guide channels members top end parts second guide channels rollers guide wall parts members top end parts first guide channels members first parts top end parts first guide channels arms members top end parts second guide channels members second parts top end parts second guide channels arms movable panel 130 connected with thefirst members motor 152 and rotating thefirst gear 155 and thesecond gear 156, the movement of themovable panel 130 in the direction of gravity can be restricted even if thearms motor 152. - In the present embodiment, the
movable panel 130 is disposed on the front-surface side of themain body 120. When themovable panel 130 assumes the operating orientation, themovable panel 130 is disposed at a tilt relative to themain body 120, whereby thesecond intake port 118b formed in the casing forward surface 113 of themain body 120 can be opened up. When themovable panel 130 assumes the operation-stopped orientation, themovable panel 130 is disposed substantially parallel to themain body 120, whereby thesecond intake port 118b formed in the casing forward surface 113 of themain body 120 and the firstopen part 119a of thedischarge port 119 can be blocked. - In the present embodiment, the
first members rollers second members guide parts rollers curved parts 165b, 175b of theguide parts members bent parts arms rollers curved parts 165b, 175b, when themovable panel 130 assumes the operating orientation, thearms first gear 155, thesecond gear 156, the second slidingmembers curved parts 165b, 175b. - The load imposed on the
motor 152 when themovable panel 130 is made to assume the operating orientation as the desired orientation can thereby be further reduced. - In the embodiments described above, the
first guide channel 168 and the second lowercurved parts 169a of thesecond guide channel 169 formed in thearm 166 have arcuate shapes slightly curved into convex shapes. - Instead of this, the second lower curved parts of the first guide channel and the second guide channel need not have arcuate shapes. For example, the first guide channel may have a linear shape, and the second lower curved part of the second guide channel may be formed in the arm so as to have a linear shape parallel to the first guide channel.
- In the embodiments described above, the
first gear 155 and thesecond gear 156 are driven by asingle motor 152. Instead of this, the first gear and the second gear may be driven by respective separate motors. Thereby, there is no need to install a transmission shaft. - In the embodiments described above, the
first guide channel 168 and thesecond guide channel 169 are slit-shaped openings passing through both surfaces of thearm 166. - Instead of this, as long as the first sliding member or the second sliding member is capable of sliding, the first guide channel and the second guide channel need not be openings. For example, the first guide channel and the second guide channel may be groove-shaped concavities provided in the arm.
- In the embodiments described above, the
first members second members drive part 151. Thefirst members movable panel 130, and thesecond members casing side surface 115 that has the main body 120 (seeFIG. 31(a) ). Therefore, due to thefirst members second members movable panel 130 connected with thefirst members main body 120 to which thesecond members movable panel 130 relative to themain body 120 is thereby varied. - Instead of this, as long as the orientation of the
movable panel 130 relative to themain body 120 can be varied, the drive part may be a mechanism for moving second members 261, 271, which have a first sliding member and a second sliding member, relative to first members 262, 272, in which a first guide channel and a second guide channel are formed. When the second members 261, 271 are moved relative to the first members 262, 272, the second guide channel is formed in the first members 262, 272 so as to have a shape with a bent top part, i.e., so that a top part of a second lower curved part and a bottom part of a bent part are continuous. The first sliding member and the second sliding member of the second members 261, 271 are respectively disposed so that when themovable panel 130 assumes the operation-stopped orientation, the first sliding member is positioned in the bottom end part of the first guide channel of the second members 261, 271, and the second sliding member is positioned in the bottom end part of the second guide channel of the second members 261, 271. - When the second members 261, 271 move relative to the first members 262, 272, the first members 262, 272 are fixed to the
main body 120, and the second members 261, 271 are connected with the movable panel 130 (seeFIG. 31(b) ). In this case, the second members 261, 271 are moved relative to the first members 262, 272 by the drive part, whereby themovable panel 130 fixed to the second members 261, 271 moves integrally with the second members 261, 271, and themovable panel 130 can therefore be moved relative to themain body 120. The orientation of themovable panel 130 relative to themain body 120 can thereby be varied. - When the
movable panel 130 assumes the operating orientation, the second members 261, 271 are restricted from moving due to the second sliding member being interlocked with the portion that defines the top end part of the curved part. Therefore, compared with a case in which the top end part of the second guide channel is not bent, the top end part of the first guide channel is bent forward, and the first sliding member is interlocked with the portion that defines the top end part of the first guide channel, for example; there is a greater distance from the portion where the first gear and the second gear contact the second members 261, 271 and support the second members 261, 271 to the portion defining the bent part of the second guide channel supporting the second members 261, 271, and the load imposed on the motor in order to maintain the orientation of themovable panel 130 can be reduced. The load imposed on the motor can also be reduced in comparison with a case in which the second members 261, 271 are supported by only the first gear and the second gear. - In the embodiments described above, the
first members second members first members movable panel 130, and thesecond members main body 120. Furthermore, thefirst members rollers second members guide parts 165, 175 (seeFIG. 32(a) ). - Instead of this, in a case in which the
first members second members first members movable panel 130 and thesecond members main body 120, themovable panel 130 may haverollers guide parts second members FIG. 32(b) . - In a case in which the
first members second members first members movable panel 130 and thesecond members main body 120, themain body 120 may haveguide parts rollers first members FIG. 33(a) .
