Description

  The present invention relates to an air conditioner that can efficiently blow out conditioned air for each operation mode.

  When conditioned air is blown out from an indoor unit of an air conditioner, it is effective to make the temperature distribution in the room uniform by blowing it horizontally in front of the casing during cooling operation and downward in heating operation. In order to send conditioned air to a place away from the indoor unit during operation, it is known that it is effective to lengthen the louver and blow out the air along the louver.

  However, a general air conditioner is configured to include a plurality of lateral louvers that are rotatable around a rotational axis parallel to the lateral direction of the casing in front of the air outlet, and if the louver is too long, Since adjacent louvers hinder rotation, the length of the louvers is limited.

As an air conditioner that solves the above problem, for example, as described in Patent Document 1, a single vertical airflow direction plate having the same size as the air outlet is used, and this is swung, thereby cooling operation. There is known a configuration in which conditioned air is sometimes blown out horizontally and conditioned air is blown out downward during heating operation.
JP-A-8-247491

  However, in the above air conditioner, in order to incline the vertical wind direction plate at a sufficient angle, it is necessary to lengthen the arm for swinging the vertical wind direction plate and make the arm center movable, and the pinion Two driving devices for driving the motor are required, which complicates the swing mechanism and increases the installation space. Moreover, the length of the up-and-down wind direction plate is substantially the same as the height of the blower outlet, and there is also a problem that the length of the wind direction plate is insufficient to send conditioned air far away.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an air conditioner capable of blowing out conditioned air efficiently with a compact mechanism for operating a wind direction plate.

  In order to solve the above problems, an air conditioner according to the present invention includes a casing having a blow-out port for blowing out air, and a wind guide panel that covers the blow-out port of the casing and its peripheral portion. The panel body has a ventilation part that allows air blown out from the air outlet to pass therethrough, and a cover body that closes the ventilation part. The cover body is pivotally attached to the casing via one rotation shaft, and the cover body is attached to the panel main body via a second rotation shaft whose axial direction is provided in parallel with the left-right direction of the casing at its upper position. A first opening / closing mechanism that is pivotably attached to the panel body and opens / closes around the first rotation axis and a second opening / closing mechanism that opens / closes the cover body around the second rotation axis are provided. Each of the mechanisms is a mechanism that converts linear motion into rotational motion, and uses the same moving body that performs linear motion as a power source. Is transmitted.

  According to the above configuration, the length of the wind guide panel is the combined length of the cover body and the panel body, that is, the length covering not only the length covering the air outlet but also the upper portion thereof. Therefore, a sufficient length can be ensured. Therefore, the wind guide panel can efficiently send conditioned air far to the horizontal direction by rotating the entire panel in the horizontal direction around the first rotation axis.

  Moreover, since the opening / closing mechanism for opening and closing the panel body and the cover body constituting the wind guide panel (wind direction plate) converts linear motion into rotational motion, the opening / closing mechanism can be made compact. In addition, since the same moving body that performs linear motion is used, the structure can be simplified and the entire mechanism can be made more compact.

  Here, the state in which the panel body is closed refers to the state in which the panel body is in contact with the casing and covers the casing, and the state in which the panel body is open refers to the state in which the panel body is rotated around the first rotation axis. The state where it is moved and separated from the casing. Further, the state in which the cover body is closed means a state in which the cover body closes the ventilation portion of the panel body, and the state in which the cover body is open means that the cover body rotates around the second rotation axis. The state which the ventilation part of the panel main body was open | released by said.

  In order to operate the first opening / closing mechanism and the second opening / closing mechanism separately with the same moving body, as described above, power is transmitted to one of the opening / closing mechanisms according to the moving direction of the moving body. You can do it.

  Specifically, the movable body is provided so as to be able to reciprocate within a certain range, and when the movable body is at an intermediate position of the movable range, both the panel body and the cover body are closed, and the movable body is in the movable range. Power is transmitted to the first opening / closing mechanism when moving to one end of the panel, and the panel body opens, and power is transmitted to the second opening / closing mechanism when the moving body moves to the other end side of the movable range. Just open it.

  The opening / closing operation of the panel body and the cover body may all be performed by the opening / closing mechanism. However, when the opening / closing operation of the panel body and the cover body is performed by the same moving body, the first opening / closing mechanism and the second opening / closing mechanism. Therefore, switching means for switching the transmission of power is required.

  Therefore, the first opening / closing mechanism includes a pin protruding from the moving body, a transmission rod in which a slit for engaging the pin is formed on one end side, and a lever body rotatably connected to the other end side of the transmission rod. And the lever body is provided so as to be rotatable about a rotation axis whose axial direction is the same as the first rotation axis, and switching means for switching the transmission of power if it is brought into contact with the panel body by rotation. Without using the power, power can be transmitted only to one of the opening / closing mechanisms according to the moving direction of the moving body.

  That is, when the moving body moves to one end side of the movable range, the pin formed on the moving body pulls the transmission rod so that the lever body comes into contact with the panel body and rotates the panel body. When the moving body reaches one end of the movable range and moves in the opposite direction (the other end), the pin slides in the slit and the power is not transmitted to the transmission rod. Therefore, if power is transmitted to the second opening / closing mechanism when the moving body moves toward the other end side, power is transmitted to only one of the opening / closing mechanisms according to the moving direction of the moving body. can do.

  The second opening / closing mechanism includes a fan-shaped gear formed around the second rotation shaft at the upper part of the inner surface of the cover body, and an opening / closing rack section formed on the moving body that meshes with the fan-shaped gear. Can be adopted. Thereby, the linear motion of a moving body can be directly converted into the rotational motion of a cover body. Further, when the movable body is installed in the casing, the second opening / closing mechanism is separated from the movable body when the panel body is opened. Can be easily combined and detached.

  The panel main body and the cover body can be provided with a biasing member that biases the panel main body and the cover body in the closing direction. Thereby, even when power is not transmitted from the opening and closing mechanism, the closed state can be reliably maintained. In particular, the first opening / closing mechanism includes a pin protruding from the moving body, a transmission rod having a slit that engages the pin on one end side, and a lever body rotatably connected to the other end side of the transmission rod. Since the panel main body cannot be closed by the first opening / closing mechanism, the panel main body can be opened / closed by providing an urging member. Examples of the urging member include a spring and a damper.

  Thus, by providing a biasing member that biases the panel body and the cover body in the closing direction, the cover body is surely closed when the panel body is open, and the panel body when the cover body is open. Is surely closed.

  Thereby, when the panel main body is opened, the panel main body and the cover body are integrated with each other, and the entire wind guide panel can take a horizontal blowing posture rotated in the horizontal direction around the first rotation axis. From the casing can be efficiently blown out forward (horizontal direction) of the casing. Further, when the cover body is opened with the panel body closed, only the cover body can take a downward blowing posture that is rotated downward, whereby air from the blowout port can be blown out below the casing. .

  Examples of the moving body in the present invention include those provided with a moving rack portion that can mesh with a pinion driven by a motor. The moving body is not limited to this, and, for example, a feed nut screwed to a feed screw can be used.

  As described above, the moving body that moves linearly has an advantage that the installation space is smaller than that of the moving body that rotates.

  As described above, according to the present invention, the panel main body having the ventilation portion that allows the air blown from the outlet to pass through the wind guide panel covering the outlet and the peripheral portion of the casing, and the cover body that closes the ventilation portion, The panel body is rotatably attached to the casing via a first rotation shaft provided at the lower end portion thereof, and the cover body is provided via a second rotation shaft provided at an upper position thereof. A first opening / closing mechanism that pivotably attaches to the panel body, opens and closes the panel body around the first rotation axis, and a second opening / closing mechanism that opens and closes the cover body around the second rotation axis. Each mechanism is a mechanism that converts linear motion into rotational motion, and uses the same moving body that performs linear motion as a power source, and transmits power to one of the opening / closing mechanisms according to the moving direction of the moving body. So that the wind guide panel Mechanism for moving is compact, and can be blown efficiently conditioned air.

Yes. In addition, the 2nd rotation axis | shaft 11 may be provided in the panel main body 9 side, and a bearing part may be formed in the cover body 8 side.

  Further, as shown in FIG. 2, the panel body 9 is rotatable with respect to the casing 2 via a first rotation shaft 10 formed at the lower end portion thereof. The first rotating shaft 10 and the second rotating shaft 11 are both arranged such that the axial direction is parallel to the casing left-right direction A.

  As shown in FIG. 3, the air conditioner of this embodiment includes a first opening / closing mechanism 12 and a second opening / closing mechanism 13 that actuate the air guide panel 7. The first opening / closing mechanism 12 and the second opening / closing mechanism 13 use the same moving body 14 that performs linear motion as a power source, convert the linear motion of the moving body 14 into rotational motion, and move the panel body 9 and the cover body 8 together. Each of the mechanisms opens and closes separately.

  Specifically, the first opening / closing mechanism 12 includes a pin 15 protruding from the moving body 14, a transmission rod 17 having a slit 16 that engages the pin 15 on one end side, and the transmission rod 17. And a lever body 18 rotatably connected to the end side. The lever body 18 is rotatably provided around a rotation shaft 19 whose axial direction is the same as that of the first rotation shaft 10. The first opening / closing mechanism 12 includes a spring 27 in the vicinity of the first rotation shaft 10 as a biasing body that biases the panel body 9 in the closing direction.

  The second opening / closing mechanism includes a fan-shaped gear formed on the inner surface of the cover body 8 around the second rotation shaft 11, and an opening / closing rack portion 21 formed on the moving body 14 that meshes with the fan-shaped gear 20. It has. Further, the second opening / closing mechanism 13 includes a spring 28 in the vicinity of the second rotating shaft 11 as a biasing body that biases the cover body 8 in the closing direction.

  The moving body 14 is formed with a moving rack portion 24 that meshes with a pinion 23 driven by a motor 22, and the movable range R can be reciprocated by driving the pinion 23. The moving body 14 is arranged such that the moving rack portion 24 and the opening / closing rack portion 21 are parallel to each other back to back, and both are joined via a joining portion 25. A pin 15 is erected at the joint portion 25. The moving body 14 is accommodated above the air flow passage 26 in the front portion of the casing 2, and is movable forward and upward from the vicinity of the air flow passage 26.

  The first opening / closing mechanism 12, the second opening / closing mechanism 13, and the springs 27, 28 that urge the first opening / closing mechanism 13 in the closing direction are installed in pairs on the left and right ends of the casing 2.

  The operation of the panel operating means having the above configuration will be described. The air conditioner is provided with a control device composed of a microcomputer. The control device is guided by the input signals of the operation mode changeover switch and the wind direction selection switch, and further takes into account the detection results of the temperature sensor, humidity sensor, etc. The attitude of the wind panel 7 is determined, and the drive control of the motor 22 is performed based on the result.

  As shown in FIG. 3, in a state where the air conditioner is stopped, the moving body 14 is located just in the middle R <b> 1 of the movable range R, and power is not transmitted to the open / close mechanisms 12, 13. First, the panel body 9 and the cover body 8 are held in the closed position by the springs 27 and 28 for biasing both in the closing direction, that is, the cover body 8 and the panel body 9 both cover the casing 2 (initial position). is doing.

  Next, when the control device decides to bring the wind guide panel 7 into the forward blowing posture as in the case where the operation mode is the cooling operation or the dehumidifying operation, the motor 22 is rotated as shown in FIG. The moving body 14 is moved forward and upward.

Due to the movement of the moving body 14, the transmission rod 17 is pulled by the pin 15, whereby the lever body 18 rotates around the rotating shaft 19, and the panel body 9 is moved against the force of the spring 27 to move the panel body 9 to the first rotating shaft 10. Turn it counterclockwise around the drawing. At this time, the fan-shaped gear 20 does not mesh with the opening / closing rack portion 24, and moves away from the casing 2 together with the cover body 8.

Is integrally rotated around the first rotation shaft 10 to face in the horizontal direction, and takes a forward blowing posture in which air from the outlet 4 is blown forward of the casing 2. In addition, the cover body 8 holds the posture closed by the spring 28 when taking the forward blowing posture.

  As in the case where the operation mode is the heating operation, when the control device determines to place the air guide panel 7 in the downward blowing posture, the motor 22 is rotated to move the moving body 14 downward and rearward.

  By this movement of the moving body 14, the pin 15 slides through the slit 16 of the transmission rod 17, and the force applied to the first opening / closing mechanism 12 from the moving body 14 is released. Thereby, the panel main body 9 is closed by the force of the spring 27 and returns to the state in contact with the casing 2, that is, the state shown in FIG.

  Further, when the moving body 14 moves rearward and downward, as shown in FIG. 5, the fan-shaped gear 20 rotates while meshing with the opening / closing rack portion 24, and the cover body 8 is moved against the force of the spring 28. Then, it is rotated around the second rotation axis 11 in the clockwise direction. When the moving body 14 reaches the lower end R3 of the movable range R, the lower blowing posture is taken.

  As described above, the air conditioner in the present embodiment can easily change the blowing direction of the air from the blower outlet 4 only by moving the moving body 14 linearly.
