Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an integrated air conditioner such as a window or wall type in which an indoor unit and an outdoor unit are integrally constructed. This invention relates to an improvement in a ventilation system that selectively communicates between external units to exhaust or intake air.

[Prior Art] Conventionally, an indoor unit and an outdoor unit constituting an air conditioner have been constructed as an integral unit and installed by being fitted into an opening in a window or wall. An integrated air conditioner is known. An integrated air conditioner like this,
Briefly explaining the present invention with reference to FIG. 6, the reference numeral 1 indicates an integrated air conditioner main body having a substantially casing shape that opens at the front, and 2 indicates the front opening. The front panel is mounted so as to be closed, and on the base 3 which is inserted and housed in the internal space, each component constituting the indoor unit 5 and the outdoor unit 6 is separated by a partition plate 4. The parts are assembled. In addition, 5 in the figure
a is a cooler that constitutes the indoor unit 5, 6a, 6
b is a condenser and a compressor that constitute the outdoor unit 6, and these are connected by a refrigerant pipe (not shown). Reference numeral 7 denotes an outdoor air blower disposed on the side of the outdoor unit 6, and 2a and 2b denote an inlet and an outlet provided on the front panel 2. Of course, although not shown in the drawings, the indoor unit 5 includes an indoor blower disposed inside the casing 8.
It is constructed so that indoor air can be sucked in through the above-mentioned suction port 2a and cooled or heated air can be blown out from the blowout port 2b.

In an integrated air conditioner with such a configuration, for example, after the refrigerant is raised to high temperature and pressure in the compressor 6b, when it passes through the condenser 6a, it is cooled and liquefied by the fan of the outdoor blower 7, and then When this refrigerant passes through the cooler 5a, it takes heat from the air sucked in from the suction port 2a by the blower fan on the indoor side and evaporates, cooling this suction air, which is then blown out from the blowout port 2b. By doing so, a cooling condition can be obtained. Furthermore, it is easily understood that by reversing the flow of the refrigerant described above, heating can be achieved by warming the suction air.

By the way, in the integrated air conditioner having the above-described configuration, a part of the partition plate 4 that partitions the indoor unit 5 and the outdoor unit 6 is provided with an opening (not shown) for air circulation. A damper is installed as a ventilation system to open and close the damper. Such a ventilation device exhausts air from the indoor side to the outdoor side or sucks air from the outdoor side into the indoor side. Conventionally, as a ventilation device for such an air conditioner, a cable wire or the like connected to a damper is used, as shown in, for example, Japanese Utility Model Application Publication No. 54-154550. A structure was adopted in which the damper was opened and closed by operating a lever or the like.

[Problem that the invention seeks to solve]

However, in the conventional ventilation system using cable wires or the like as described above, the operating section on the front panel 2 side and the ventilation damper provided on the internal partition plate 4 are arranged with a considerable distance from each other. Therefore, when installing it, it is necessary to attach complicated wire supports, support shaft members, etc., which increases the number of component parts, complicates assembly work, and causes play in the wire. This method has drawbacks such as being easy to use, unfavorable in terms of mass production, prone to elongation after long-term use, and not being able to securely open and close the damper.

The present invention has been made in view of the above-mentioned circumstances, and has a simple structure with a small number of parts, excellent ease of assembly, improved operational feeling when opening and closing a ventilation damper, and reliable opening and closing operations.

The feature is that it is composed of. Then, the outer ends (operating end 13
b, 14b) are the front panel 2 of the air conditioner main body 1 (actually, the front part 12b of the mounting plate 12).
It is arranged so as to protrude to the outside from operation ports 19a and 19b provided in a cover 18) attached to the cover 18).

Note that this embodiment shows a case where the damper plate 11 described above and the opening lever 13 that opens and closes the damper plate 11 are configured separately, and in this case, the damper plate 11 is screwed to the partition plate 4 side. A damper spring 20 in the shape of a leaf spring is normally biased in the closing direction. Also, a lever portion 1 protruding forward from this damper plate 11 is provided.
1a is a partition plate side portion 4 on the side surface of the casing 8;
a tongue piece portion 21 cut and formed in a direction a and an electrical component cover 22 disposed at the rear of the electrical component mounting plate 12;
The opening lever 13 is slidably supported by a recess formed in the bent portion 22a, and the inner end 13a of the opening lever 13 moves forward and backward at the tip of the lever portion 11a, so that the damper plate 11 is moved when engaged. It is configured to move in the opening direction against the biasing force of the spring 20, and to move in the closing direction due to the biasing force of the spring 20 when separated, thereby closing the air flow opening 10. Here, 11b in FIG.
20a is an engagement hole of the damper spring 20 into which the engagement pin 11b is inserted.

Furthermore, in FIG. 3, 23 is an indoor side blower, 24 is this indoor side blower 23 and the above-mentioned outdoor side blower 7.
A drive motor that drives the indoor blower 23
A part of the air sucked in from the room is sent into the outdoor unit 6 side when the air flow port 10 is opened, and is sucked in by the outdoor side blower 7, thereby performing an exhaust operation.

Further, the open lever 13 and the close lever 14 as damper levers that characterize the present invention are as shown in FIG. 1, FIGS. 4a and 4b, and FIG. 5.
They are connected by a connecting member 16 and are configured to operate in conjunction with each other. To explain this in detail, these levers 13 and 14 are formed by bending their inner ends so as to be spaced apart from each other, and the tips of the bent portions 13c and 14c are further bent and formed, as shown in the figure. As a result, it is extended toward the rear. Engagement protrusions 30a and 30b are protruded from these spaced and extended portions, respectively, and screw holes are drilled in the side surface 12a of the mounting plate on the fixed side between the levers 13 and 14. At both ends of the connecting member 16, which is screwed to the connecting member 15a and rotatably supported, there are engaging holes 31a, 31 into which the above-mentioned engaging protrusions 30a, 30b are engaged.
b is formed so that both levers 13 and 14 are operated in conjunction with each other. Here, the above-mentioned engagement holes 31a and 31b are formed to have a long groove shape as shown in the figure, but this allows the relative movement of the respective levers 13 and 14 to be performed smoothly, and also , to absorb formation errors, etc. between each member.

Further, one end 17a of the spring member 17 is locked to the tip of a locking piece 32 extending laterally from the center of the connecting member 16, and the other end of the spring member 17 is Spring locking piece 3 formed by cutting and raising a part of the mounting plate side part 12a
3, and by applying rotational force to the connecting member 16, both levers 13 and 14 are moved in opposite directions, and further maintained in a position where the damper plate 11 is in the open or closed state. The structure is such that That is, the locking position on the locking piece 32 side where the spring member 17 is locked is the screw 1 which is the rotation axis of the connecting member 16.
5 portion and the other end 17b are locked together. Spring locking piece 33
By adopting a configuration that crosses over the line segment connecting the parts, it becomes possible to maintain the above-mentioned open and closed states. In addition, there is a problem in adopting such a configuration when the opening lever 13
When the damper plate 11 is opened by pressing the damper plate 11, a force is required to resist the urging force of the damper spring 20 acting on the damper plate 11. On the other hand, when the closing lever 14 is operated, the force of the damper spring 20 described above is required. The biasing force acts in a direction that assists the operation, and as a result, the operating forces of both levers 13 and 14 become unbalanced. For this reason, this embodiment shows a case in which the biasing force of the spring member 17 described above acts to assist when the opening lever 13 is pressed, and acts in the opposite direction when the closing lever 14 is operated.

In addition, in this embodiment, the fixed side spring locking piece 33 that locks the other end 17b of the spring member 17 described above is configured so that it can hold the side part of the spring member 17 during the opening operation shown in FIG. 4a. Furthermore, the spring member 17b that is locked by the spring locking piece 33 is formed in the shape of a crank, so that the spring member 17 does not come off regardless of the repeated operation of the damper lever. The structure is designed to prevent such problems and ensure smooth spring operation.

In addition, in this embodiment, the opening/closing lever 1 described above is
3' and 14 are configured so that they can be assembled integrally with a gripping portion 34 that can grip the portions that are close to each other in front of the bent portions 13c and 14c. By having such a configuration, these levers 13, 1
4 mutually serve as guide members, and also have the advantage of being able to be assembled as a unit during assembly. In addition, the one indicated by 35 in FIG.
The protrusion provided on the sliding surface between the two levers allows the sliding operation to be performed smoothly when operating these levers with minimal frictional force.

Further, in the embodiment described above, flange-shaped stopper pieces 36a, 36b are provided near the operating ends 13b, 14b of the opening and closing levers 13, 14, and stopper pieces projecting laterally at the bent portions 13c, 14c. 37a, 37b are integrally formed, and these stopper pieces 36a, 36b; 37a, 37b,
As shown in FIGS. 4a, b and 5, the inner surface of the cover 18 attached to the front surface portion 12b of the mounting plate and the stepped portion 38 formed by bending the side surface portion 12a of the mounting plate are alternately formed. It is configured so that it comes into contact with the By adopting such a configuration, the operating stroke of each lever 13, 14 can be properly and reliably secured, and the sound caused by the collision of both stopper pieces with each surface formed of sheet metal material can be reduced to a notching sound. This makes it possible to achieve advantages such as being able to be used as a

According to the ventilation system according to the present invention having the above configuration, as shown in FIGS. 4a and 4b, the opening lever 13
By pressing the lever 13, the damper plate 11 can be moved toward the outdoor unit 6 against the biasing force of the damper spring 20, opening the air flow opening 10. This allows air to be exhausted outdoors. At this time, the operating end 14b of the closing lever 14 remains in a state protruding to the outside, while the amount of protrusion of the opening lever 13 is smaller than this.
The operator can easily check this from the outside and grasp the open/closed state of the damper. Furthermore, when the closing lever 14 is pressed, the opening lever 13 moves toward the indoor unit 5 side, that is, the front side of the air conditioner body 1 due to the action of the connecting member 16, and thereby moves away from the damper plate 11. The damper plate 11 operates to close the air flow opening 10 by the biasing force of the damper spring 20, thereby making it possible to obtain a closed state of the damper. At this time, in this embodiment, since the damper plate 11 and the opening lever 13 for opening the damper plate 11 are constructed separately, a reliable closed state can be obtained when the damper is closed.

Further, according to the above-described configuration, the open lever 13 and the close lever 14 are used as damper levers for opening and closing the damper, and these levers 1
3 and 14 are operated in conjunction with each other in opposite directions by the connecting member 16, which improves the operational feeling when opening and closing the ventilation damper, and ensures a reliable and reliable opening and closing state of the damper. Moreover, the operator can easily confirm whether the damper is open or closed.

Furthermore, as in the embodiment described above, when the opening lever 13 constituting the damper lever and the damper plate 11 which opens and closes the air communication opening 10 when pressed by the opening lever 13 are constructed separately, the opening lever 13 described above The unit consisting of the mounting plate 12 for mounting electrical parts, etc. attached thereto, can be easily removed and repaired regardless of the damper side, and this has great advantages in terms of maintenance and the like.

Here, in this embodiment, a case will be explained in which the operating ends 13b and 14b of the open lever 13 and the close lever 14 are arranged side by side in the upward and downward directions and protrude on the front panel 2 of the air conditioner main body 1. However, the present invention is not limited to this, and modifications such as arranging them side by side in the left and right directions are also possible. In this case, it is preferable to bend the tip of one of the levers into an L-shape, and to protrude the operating end at a position parallel to the other lever in the horizontal direction.

Note that the present invention is not limited to the structure of the embodiment described above, and the shape and structure of each part may be modified and changed as appropriate. For example, as shown in FIGS. 7 and 8, the opening lever 13 and The damper plate 11 may be formed integrally with the damper plate 11, or, as shown in FIGS. ), and various other modifications are conceivable, such as connecting them in series. The former integrated structure reduces the number of overall components including the damper biasing spring, and improves ease of assembly.
Furthermore, in the connection structure that allows for the latter,
This provides advantages such as ensuring reliable opening and closing operations of the damper, especially ensuring a closed state.

Furthermore, in each of the embodiments described above, a case has been described in which the ventilation device according to the present invention is applied to open and close the exhaust side of an air conditioner, but the present invention is not limited to this, and It is clear that the present invention may be used as an air conditioner, and is not intended to limit the type of air conditioner.

[Effects of the Invention] As explained above, according to the ventilation device for an air conditioner according to the present invention, two levers for opening/closing operation and a connecting member for moving these levers in opposite directions are used. Therefore, despite the simple and inexpensive configuration, the ventilation damper has an excellent operating feeling when opening and closing, improving operability, as well as ensuring reliable opening and closing operation of the damper, improving operability. It is said that it can eliminate the conventional problems such as wind leakage, and also allows the operator to easily check whether the damper is open or closed, and is also superior in terms of ease of assembly. It has various excellent effects.
