[Detailed description of the device] [Industrial applications]

[0001] The present invention relates to an improved conditioned air blowing device in an air conditioner such as an air conditioner.

[0002]

[Problems to be solved by conventional techniques and devices]

 Air-conditioning air blowers in this kind of air-conditioning equipment generally have the above-mentioned inside of a case in which an air-conditioning air blow-out port is opened on the front face and an air-conditioning air introduction hole is opened at a portion inside thereof. A shield that adjusts the air volume by adjusting the opening area of the ventilation hole is provided rotatably around an axis extending in the direction intersecting the flow direction of the conditioned air. A control body for controlling around the rotation axis of the shield is rotatably provided around an axis extending concentrically with the rotation axis of the shield, and the wind direction of the conditioned air is provided to the control body. A large number of blades are provided for controlling in the direction intersecting the axis of the control body, and the operating lever of the interlocking mechanism for rotating and operating each of these blades is projected forward from the control body. Structure provided in this way It has become.

By the way, the air-conditioning equipment is not always used and may or may not be used depending on the time. Conventionally, even if the air-conditioning equipment is not used, the air-conditioning air outlet is opened. Since it was left as it was, dust and dust in the room entered the inside of the blowing device when not in use, and these dust and dust were ejected into the room together with the conditioned air when the air conditioning equipment was used again. There were problems such as making the room dirty and making the inside of the case visible from the outside, which deteriorated the appearance. With respect to this point, the inventor of the present application can solve the above-mentioned problems when the air conditioning equipment is not used, if the shield for adjusting the air flow is configured to freely rotate from the posture of opening / closing the ventilation hole to the posture of closing the outlet. , I thought it could be prevented without complicating the structure.

However, conventionally, since the operation lever for rotating the blades provided on the control body all at once is projected to the front of the control body, as described above, the air outlet is provided by the shield body. If it is configured to be closed, the shield hits the operation lever in the control body, and in order to avoid this, the turning radius of the shield must be increased, which increases the size of the device. .

An object of the present invention is to make it possible to block the air outlet with a shield for adjusting the air flow without increasing the size of the device.

[0006]

[Means for Solving the Problems]

 In order to achieve this object, the present invention provides a case in which an air-conditioning air outlet is opened and a vent hole for introducing the air-conditioning air is opened in a portion inside the air-conditioning air outlet, and a shield for adjusting the air volume is provided in the case. It is rotatably provided from a posture of increasing / decreasing the opening area of the vent hole to a posture of closing the air outlet, and is arranged at appropriate intervals along a longitudinal direction of a control body provided inside the case. A plurality of wind direction control vanes are rotatably mounted, and a void space is formed in the control body, the void space being open toward the outlet, and the vane plates are placed in the void space. The rotary operation body in the interlocking mechanism that rotates in unison is provided such that the tip edge of the operation body is located inside the shield in a state in which the outlet is blocked.

[0007]

[Operation and effect of the device]

 With this configuration, the air outlet can be closed with a shield for adjusting the air volume, so when the air conditioning equipment is not in use, dust or dust may enter the inside of the case through the outlet, or It is possible to prevent the appearance from deteriorating while the inside remains visible without complicating the structure. Further, by providing the operating body for rotating the blades at the same time in the void formed in the control body, it is possible to prevent the operating body from largely protruding from the tip edge of the control body. Since the gap between the inner surface of the shield and the tip edge of the control unit can be reduced when the outlet is closed, the outlet can be closed with the shield without increasing the turning radius of the shield. You can

Therefore, according to the present invention, the blow-out port can be closed by the shield for adjusting the air flow without increasing the turning radius of the shield, so that the device becomes large and complicated. In addition, it has the effect of preventing dust or dust from entering the case and deteriorating its appearance when the air conditioning equipment is not used.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings (FIGS. 1 to 9) in the case where the present invention is applied to an apparatus that blows out conditioned air by utilizing a panel installed upright in a room. In the figure, reference numeral 1 indicates a hollow partition panel that is erected in a room, and an air conditioning air intake port (not shown) is provided on the lower surface of the panel 1, and a double floor is installed in the intake port. While the conditioned air blown into the empty space 3 of 2 is taken in, or a duct is installed in the empty space 3 is connected to the upper end of the front plate 1a of the panel 1, the left and right mounting holes 4 are attached. The three cases 5 of the blowing device are fitted in the mounting holes 4 by fitting the panels 1 from the front side.

The case 5 is formed in a substantially semicircular cross section. The case 5 has a left-right long outlet 6 on the front surface thereof, and the bottom surface of the case 5 has a left-right elongated shape communicating with the inside of the panel 1. Vent holes 7 are opened, and left and right longitudinal engagement grooves 8 are formed on both upper and lower surfaces near the front end. Then, as shown in FIGS. 8 and 9, with the flange 5a formed on the front surface abutting on the front plate 1a of the panel 1, both the upper and lower engaging grooves 8 are fixed to the inner surface of the panel 1. The case 5 is attached to the panel 1 by engaging the locking pieces 10 formed by cutting and raising with the horizontal pieces 9a and 9b of 9. Further, the lower horizontal piece 9b of the reinforcing member 9 of the panel 1 is provided with a communication hole 11 for guiding the conditioned air taken into the panel 1 into the case 5.

Inside the case 5, a shield 12 for adjusting the air volume by increasing / decreasing the opening area of the ventilation hole 7 and a blowing direction of the conditioned air blown out from the blowing port 6 are set in a vertical direction. A control body 13 having a hollow and flat plate shape for controlling The control body 13 is equipped with a large number of vane plates 14 for switching and adjusting the wind direction to the left and right.

The shield 12 and the control body 13 are configured to rotate concentrically via the first and second oil type brake bodies 15 and 16 as described below. That is, the shield 12 is formed in an arcuate cross section so as to extend along the inner surface of the case 5, and has disk-shaped operation plates 12a and 12b at both ends thereof with knurled irregularities on the outer circumference. The left and right operation plates 12a and 12b are integrally connected to each other, and one of the left and right operation plates 12a is provided with a through hole 17 having a smoothly formed inner circumference, and the other operation plate 12b is formed with an inner circumference. A spline hole 18 formed with spline teeth and a positioning hole 19 having a larger diameter than the spline tooth are drilled so that the positioning hole 19 is located on the outer side. On the other hand, one of the both end face plates 13a and 13b of the control body 13 is formed. The end face plate 13a is provided with a spline hole 20 having spline teeth formed on the inner periphery thereof, and the other end face plate 13b is provided with a through hole 21 having a smooth inner peripheral face. The first brake body 15 provided on one side plate 5b of the case 5 is formed by attaching a rotary shaft 23 to a cylinder body 22 with a collar, and the cylinder body 22 is attached to one side plate 5b of the case 5 by an appropriate means. One operation plate 12a of the shield 12 is rotatably fixed to the cylindrical body 22, and the spline portion 23a formed on the rotary shaft 23 of the first brake body 15 is fixed to the cylindrical body 22. The control body 13 and the rotary shaft 23 are integrally rotated by engaging the spline hole 20 formed in the one end face plate 13a of the control body 13. Further, the cylinder 22 of the second brake body 16 is fixed to the inner surface of the other side plate 5c of the case 5, and the other operation plate 12b of the shield 12 is fitted to the cylinder 22. By engaging the spline portion 23a formed on the rotary shaft 23 of the second brake body 16 with the spline hole 18 of the other operation plate 12b of the shield 12, the shield 12 and the second brake body 16 are engaged. The rotary shaft 23 and the rotary shaft 23 are integrally rotated. A small-diameter guide shaft 23b is projected from the rotary shaft 23 of the second brake body 16, and the other end face plate 13b of the control body 13 is rotatably fitted on the guide shaft 23b.

The first and second brake bodies 15 and 16 are configured as shown in FIGS. 5 and 6. That is, a partition plate 25, which is in contact with the outer peripheral surface of the rotary shaft 23, is fixed to the inner peripheral surface of the cylindrical body 22, and an orifice 26 is formed in the partition plate 25. On the other hand, the fin plate 28 that is slidably contacted with the inner peripheral surface of the cylindrical body 22 is fixed to the outer peripheral surface of the rotary shaft 23 while closing the valve plate 27 of the rotary shaft 23. Of the two surfaces, the partition plate 25 is closed by a valve plate 30 made of a leaf spring fixed to the surface opposite to the valve plate 27, and the space between the cylinder 22 and the rotary shaft 23 is filled with oil. It was done. Therefore, in a normal state, the orifice 26 of the partition plate 25 and the orifice 29 of the fin plate 28 are closed by the valve plates 27 and 30, respectively, and the partition plate 25 and the fin plate 28 divide the first part. Since the oil cannot flow between the second oil chamber 31 and the second oil chamber 32, the rotating shaft 23 is held unrotatable, but a certain amount of force is applied to the rotating shaft 23 in the direction of arrow A. As a result, the pressure in the first oil chamber 31 increases, and the oil flows into the second oil chamber 32 through the orifice 26 of the partition plate 25 while elastically deforming the valve plate 27 of the partition plate 25, As a result, the rotation shaft 23 rotates in the A direction. On the contrary, when the force for rotating the rotary shaft 23 in the direction of the arrow B reaches a certain level, the pressure in the second oil chamber 32 increases, and the oil elastically deforms the valve plate 30 in the fin plate 28. At the same time, the oil flows into the second oil chamber 32 from the first oil chamber 31 via the orifice 29 of the fin plate 28, and as a result, the rotation of the rotary shaft 23 in the B direction is allowed. Therefore, the shielding body 12 and the control body 13 are rotatable in any direction when a certain amount of force is applied, and when the rotation is stopped, they are held in the postures at that time. The force capable of rotating the rotary shaft 23 depends on the spring constants of the two valve plates 27 and 30.

Each of the vane plates 14 is configured to be fitted into the control body 13 from the rear side, and the outer peripheral surface thereof is close to the inner surface of the shield body 12. The blades 14 are configured to be rotatable about vertical axes by inserting projections 33 projecting inwardly into the holes into holes 34 formed on both upper and lower surfaces of the control body 13. On the other hand, in the rear part of each vane plate 14, an operating rod 35 that constitutes an interlocking mechanism is arranged so as to extend parallel to the control body 13, and a forward opening formed by cutting out the interlocking rod 35. The engaging groove 36 is rotatably engaged with the narrow width locking portion 14a formed at the rear portion of each blade 14. Further, a fan-shaped operation body 37 in a plan view, which constitutes an interlocking mechanism together with the interlocking rod 36, is attached to a pin 38 at a rear end portion of the control body 13 at a portion corresponding to an arbitrary blade plate 14. Pivotally rotatably horizontally and the front end edge of the operating body 37 is exposed to the front through a notch hole 39 formed in the control body 13 while being connected to the rearward projecting portion of the operating body 37. A pair of left and right holding pins 40, 40 sandwich and lock one blade plate 14. The locking portion 14a of the vane plate 14 to which the operating body 37 is attached is locked in the engagement groove 36a of the interlocking rod 35, which is substantially .OMEGA. Therefore, when the operating body 14 is rotated in the left-right direction as shown by an arrow in FIG. 7, one blade plate 14 sandwiched by the sandwiching pin 40 is horizontally rotated, and the interlocking rod 35 is horizontally moved accordingly. As a result, the blades 14 simultaneously horizontally rotate, and the ejection direction of the conditioned air is controlled left and right. The outer peripheral surface of the operating body 37 is formed with knurled protrusions for facilitating the turning operation.

The shield 12 is configured to rotate from a posture in which the ventilation hole 7 is completely closed to a posture in which the blowout port 6 is closed, and when the shield 12 closes the blowout port 6. The tip of the operating body 37 is located inside the shield 12.

In the above configuration, the shield 12 is rotated as shown by an arrow C in FIG. 8 to increase or decrease the opening area of the ventilation hole 7 in the shield 12, whereby the air volume of the conditioned air can be adjusted. On the other hand, when it is pivoted largely in the direction of the arrow D, the outlet 12 can be closed by the shield 12. Further, when the control body 13 is picked up with a finger and rotated up and down, the vertical direction of the conditioned air can be controlled. Further, when the operation body 37 provided in the control body 13 is horizontally rotated. , The direction of the conditioned air to the left and right can be controlled.

As described above, when the air conditioning facility is not used, the outlet 6 can be closed by the air volume adjusting shield 12, that is, the air volume adjusting shield 12 is blown out. Since it also serves as a lid for closing the mouth 6, the structure is designed to prevent dust and dirt from entering the case 5 when the air-conditioning equipment is not used, or to make the inside of the case 5 visible from the outside and to deteriorate the appearance. It can be prevented without complication.

Since the operating body 37 for rotating the blades 14 at the same time is provided in the space of the control body 13, the operating body 37 is projected forward from the front end edge of the control body 37. It is possible to rotate without doing so, in other words, the space dimension between the inner peripheral surface of the shield 12 and the front end edge of the control body 13 in a state where the outlet 6 is closed can be reduced. The outlet 12 can be closed by the shield 12 without increasing the turning radius of the shield 12 or reducing the front-rear width dimension of the control body 13. Therefore, the outlet 12 can be closed by the shield 12 without increasing the size of the device. Although the control body 13 may be fixed so as not to be rotatable, if the control body 13 is configured to be rotatable so that the wind direction can be controlled in the vertical direction as in the embodiment, the depth of the control body 13 is reduced. Since the outlet 12 can be closed with the shield 12 without reducing the width dimension, there is an advantage that the control function of the wind direction by the controller 13 is not impaired.

In the above-described embodiment, the shield 12 is provided inside the case 5, but the shield 12 is rotated along the outer surface of the case 5 as shown by the chain double-dashed line in FIG. It may be configured to move, or the interlocking rod 35 may be configured to be directly moved by the operating body 37. It goes without saying that the present invention can be applied not only to the blowout device provided on the panel but also to a blowout device for conditioned air in air conditioning equipment such as an air conditioner in general.
