Conventionally, the indoor unit and outdoor unit that make up the air conditioner are integrated, and the unit is configured to be installed by being fitted into an opening in a window or wall. air conditioners are known. An integrated air conditioner like this,
To briefly explain the present invention using FIG. 6, reference numeral 1 denotes an integrated air conditioner body having a substantially housing shape, and 2 denotes a body installed to close the front opening of the air conditioner. On the front panel and on the base 3 accommodated in the interior space, the components constituting the indoor unit 5 and the outdoor unit 6 are assembled, separated by a partition plate 4. In the figure, 5a is a cooler constituting the indoor unit 5, and 6a and 6b are a condenser and a compressor constituting the outdoor unit 6, and these are connected by a refrigerant pipe (not shown). In addition, 7 is an outdoor fan installed on the outdoor unit 6 side, and 2a,
Reference numeral 2b represents 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, which takes in the indoor air from the above-mentioned suction port 2a and blows out cooled or heated air from the blow-off port 2b. It is configured so that it can be done.

By the way, in the above-mentioned integrated air conditioner, a part of the partition plate 4 that partitions the indoor unit 5 and the outdoor unit 6 is usually provided with an air circulation opening (not shown). A damper that opens and closes is installed as a ventilation system. Such a ventilation device plays the role of exhausting air from the indoor side to the outdoor side and sucking 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, and a cable wire provided at the other end of the wire 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 attempts to solve]

However, according to the conventional device using the above-mentioned cable wires, etc., the operation 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. It is necessary to attach complicated wire supports and spindle members, etc., which increases the number of component parts, complicates assembly work, and tends to cause play in the wire, which is not desirable in terms of mass production. In addition, the damper tends to elongate due to long-term use, and the damper cannot be opened and closed reliably. In particular, when operating the damper using a wire or the like as described above, there are problems in terms of the operational feeling, and it cannot be said that it can provide an appropriate operational feeling to the operator.

The present invention has been developed in view of the above-mentioned circumstances, and has a simple structure with a small number of parts and excellent ease of assembly, which greatly improves the operating feeling when opening and closing the ventilation damper, and ensures reliable opening and closing operations. The object of the present invention is to provide an inexpensive ventilation device for an air conditioner that allows the operator to easily check whether the ventilation damper is open or closed.

[Means for solving problems]

According to the ventilation device for an air conditioner according to the present invention,
The outer end is slidably supported in the longitudinal direction along a mounting plate made of a sheet metal material within the main body of the air conditioner so as to operate a damper for controlling the opening and closing of the air flow opening provided between the indoor and outdoor units. uses a damper lever that faces the outside from an operation port provided on the front panel side of the air conditioner main body, and the mounting plate is folded away from the damper lever along a direction perpendicular to the longitudinal direction of the damper lever. A stepped portion is formed by bending the mounting plate, and a stopper piece that restricts the inward movement of the damper lever by colliding with the stepped portion of the mounting plate is provided to protrude from a part of the side of the damper lever. It is something.

[Effect]

According to the present invention, the damper can be easily and reliably controlled to open and close using the damper lever, and the operating stroke of the damper lever can be properly and reliably secured. The sound generated by the collision with the stepped portion formed on the plate can be used as a notch sound during operation.

〔Example〕

Hereinafter, the present invention will be explained in detail using embodiments shown in the drawings.

1 to 6 show an embodiment of the ventilation system for an air conditioner according to the present invention, and the explanation of FIG. 6 described above will be omitted.

In these figures, indoor and outdoor units 5 and 6 are shown.
An air circulation opening 10 (fifth
), the damper plate 11 is externally operated.
The ventilation system of the air conditioner, which is opened and closed controlled by An opening lever 13 that is slidably supported in a direction and is operated to open by pressing a damper plate 11 integrally connected to an inner end 13a side of the damper plate 11 toward the outdoor unit 6; The mounting plate side portion 12
A closing lever 14 that is slidably supported along the inner surface of the closing lever 14, and a lever that is spanned between the inner end 14a side of this closing lever 14 and the opening lever 13, and whose central portion is the fixed side. A connecting member 16 that moves the levers 13 and 14 in opposite directions by being pivotally supported on the mounting plate side portion 12a via a screw 15 serving as a support shaft, and a connecting member 16 that applies an urging force to the connecting member 16. The opening lever 13 is configured by a spring member 17 and the like that moves the opening lever 13 toward and away from the damper plate 11 and maintains the damper plate 11 in the open and closed state. The outer ends (operating ends 13b, 14b) of the pair of opening levers 13 and closing levers 14 described above are attached to the front panel 2 of the air conditioner body 1 (actually, the front part 12b of the mounting plate 12). covered cover 1
8) so as to protrude to the outside from operation ports 19a and 19b provided in the terminals 8).

This embodiment shows a case where the damper plate 11 described above and the opening lever 13 for opening and closing the damper plate 11 are constructed separately, and in this case, the damper plate 11 is screwed to the partition plate 4 side. It is always biased in the closing direction by a damper spring 20 in the shape of a leaf spring. 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 opening direction by 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. 5, 23 is an indoor side blower, 24 is this indoor side blower 23 and the above-mentioned outdoor side blower 7.
This indoor blower 23 is
Due to this function, 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 also sucked in by the outdoor side blower 7, thereby performing an exhaust operation.

Further, as shown in FIGS. 1, 2a, and 3, the open lever 13 and the close lever 14, which form a pair as damper levers, are connected by a connecting member 16 and are configured to operate in conjunction with each other. has been done. To explain this in detail, these two levers 13, 1
4, the inner ends thereof are bent to be spaced apart from each other, and the tips of the bent portions 13c and 14c are further bent to extend rearward. has been done. Engagement protrusions 30a and 30b are protruded from the spaced apart 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. A connecting member 16 is screwed to 15a and rotatably supported.
Engagement holes 31a and 31b into which the above-mentioned engagement protrusions 30a and 30b are engaged are formed at both ends of the levers 13 and 14, so that the 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 each lever 13 and 14 to be performed smoothly and , to absorb formation errors, etc. between each member.

Furthermore, 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 17b of the spring member 17 is It is locked by a spring locking piece 33 cut and formed in a part of the plate side part 12a, and by applying rotational force to the connecting member 16, both levers 13 and 14 are moved in mutually opposite directions, and the damper plate is further moved. The structure is such that the state is maintained at the open or closed position of 11. That is, the locking position on the locking piece 32 side where the spring member 17 is locked is the screw 15 which is the rotation axis of the connecting member 16.
By adopting a configuration in which the spring locking piece 33 connects the spring locking piece 33 with the other end 17b locked, the above-mentioned open and closed states can be maintained. In addition, a problem in adopting such a configuration is that when the damper plate 11 is opened by pressing the opening lever 13, the biasing force of the damper spring 20 acting on the damper plate 11 is reduced. On the other hand, when the closing lever 14 is operated, the biasing force of the damper spring 20 mentioned above acts in a direction to assist the operation, resulting in an imbalance in the operating forces of both levers 13 and 14. It is. Therefore, in this embodiment, the above-mentioned spring member 1
A case is shown in which the biasing force 7 acts to assist when the opening lever 13 is pressed, and works 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 such that it can hold the side part of the spring member 17 during the opening operation shown in FIG. The spring locking piece 33 is formed with a predetermined inclination.
The other end 17b of the spring member that is engaged with the spring member is formed into a crank shape to prevent problems such as the spring member 17 coming off and to ensure smooth spring operation regardless of repeated lever operations. The structure is such that it can be secured.

In addition, in this embodiment, the opening/closing lever 1 described above is
3, 14, the bent portions 13c, 14c
In order to be able to mutually grip the parts that are close to each other in front of the opening lever 13, the gripping part 34 having a substantially L-shape is connected to the other closing lever 1 from the side of the opening lever 13.
The opening lever 13 of this closing lever 14 extends to the 4 side.
By holding and gripping the surface opposite to the sliding surface, the two can be assembled integrally in a state where they can slide relative to each other.
With such a configuration, both levers 13 and 14 mutually serve as guide members, and problems such as the lever coming off or shifting during operation can be eliminated, and also during assembly. This has the advantage that it can be assembled as a unit to the electrical component mounting plate 12. The reference numeral 35 in FIG. 4 is a protrusion provided on the sliding surface between the levers 13 and 14, and is used to smoothly slide the levers by minimizing frictional force when operating the levers. Of course, it will be obvious that such a protrusion may be provided on the inner surface of the grip portion 34 that is in contact with the closing lever 14.

Now, according to the present invention, the side surface 12 of the electrical component mounting plate 12 made of a sheet metal material is configured to actuate the damper for controlling the opening and closing of the air flow opening 10 as described above.
an opening/closing lever 13, which serves as a damper lever, is slidably supported in the longitudinal direction along the front panel 2, and has outer ends 13b and 14b facing the outside through operating ports 19a and 19b provided on the front panel 2 side; 14
In the ventilation system for an air conditioner, the step portion 38 is formed by bending the side surface portion 12a of the mounting plate so as to be spaced apart from the levers 13, 14 in a direction perpendicular to the longitudinal direction thereof. Stopper pieces 37a and 37b are provided and restrict the inward movement of both levers 13 and 14 by colliding with the step 38 of the mounting plate side surface 12a.
The levers 13 and 14 are distinctive in that they partially protrude from the sides.

That is, according to the present invention, the operating strokes of the open and close levers 13 and 14 as damper levers are appropriately ensured, and the operating sound during operation is reduced by the stepped portion 38 formed by bending the mounting plate 12 made of sheet metal material. Stopper piece 37 formed on the lever side
This is caused by the collision sound with a and 37b.

In addition, in this embodiment, the opening and closing levers 13,
Flange-shaped stopper pieces 36a, 36b are provided near the operating ends 13b, 14b of the bent portion 13.
The stopper pieces 36a, 36b, 37a, 37b are integrally formed with the stopper pieces 37a, 37b that protrude laterally at the portions c and 14c.
as shown in FIGS. 1 and 2 a and b, so that they alternately abut against the inner surface of the cover 18 attached to the mounting plate front part 12b and the step part 38 of the mounting plate side part 12a. It consists of With this configuration, the operating strokes of the levers 13 and 14 are properly and reliably secured in both directions, and the noise generated when both stopper pieces collide with each surface formed of sheet metal material is suppressed. It can be used as a sound.

According to the ventilation system according to the present invention having the above configuration, as shown in FIG. 1 and FIG. 6 side against the biasing force of the damper spring 20 to open the air flow opening 10, thereby allowing air to be exhausted from the room to the outside. At this time, the operating end 14b of the closing lever 14 remains protruding to the outside, while the amount of protrusion of the opening lever 13 is smaller than this, so the operator can easily check this from the outside and operate the damper. It is possible to grasp the open/closed state. Also, when the closing lever 14 is pressed, the connecting member 1

side, that is, to the front side of the air conditioner main body 1, and thereby move in a direction away from the damper plate 11. Therefore, the damper plate 11 closes the air circulation opening 1 due to the biasing force of the damper spring 20.
0, and it becomes possible to obtain a closed state of the damper.

Further, according to the above-described configuration, the open lever 13 and the close lever 14 are used to open and close the damper, and the levers 13 and 14 are linked and switched in opposite directions by the connecting member 16. This improves the operation feeling when opening and closing the ventilation damper, and ensures a reliable and reliable damper opening/closing state.Furthermore, the operator can easily check the damper's open/closed state. It has the advantage of being possible.

Furthermore, in this embodiment, a case has been described 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, the tip of one of the levers may be bent into an L-shape, and the operating end may be provided in a protruding 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, structure, etc. of each part may be modified and changed as appropriate. For example, in the above-mentioned embodiment, a case was explained in which a pair of opening and closing levers 13 and 14 were used as damper levers, but the present invention is not limited to this, and a configuration using a single lever may also be used. It should be obvious.

Furthermore, in each of the above-mentioned embodiments, 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.
