Description
SPECIFICATION
Ventilation device for an air conditioning apparatus
The present invention relates to a ventilation device for an air conditioning apparatus. More particularly, it relates to an improvement in a ventilation device for performing selective communication between a room side unit and an outdoor side unit to effect air intake and discharge operations in an integral type air conditioning apparatus such as a window or wall type one wherein the room side unit and the outdoor side unit are placed on a common base of the air conditioning apparatus.
There has been known an integral type air conditioning apparatus which has an integral construction of a room side unit and an outdoor side unit constituting an air conditioner, and which is adapted to be fitted and fixed to an opening formed in a window or a wall.
An integral type air conditioning apparatus having the ventilation device according to the present invention will be described with reference to Fig. 6.
A reference numeral 1 designates a main body for an integral type air conditioning apparatus having a substantially box-like shape with an opening at the front side. A front panel 2 is attached to the front opening to close it. A base plate 3 is received in the inner space of the main body. On the base plate 3, elements constituting a room side unit 5 and an outdoor side unit 6 are installed and a partition plate 4 is placed between the room side unit 5, and the outdoor side unit 6. A cooling device 5a as an element of the roon side unit 5 and a condenser 6a and a compressor 6b as elements of the outdoor side unit 6 are connected by refrigerant pipes which are not shown in the drawing. A blower 7 is placed in the outdoor side unit 6.
The front panel 2 is provided with an inlet port 2a and an outlet port 2b. A blower (not shown) as an element of the room side unit 5 is placed in the casing 8 so that air in a room is sucked from the intake port 2a to be cooled or heated and the air is discharged through the outlet port 2b.
In the conventional integral type air conditioning apparatus having the construction as above-mentioned, cooling operation of the air conditioning apparatus is carried out as follows. A refrigerant is supplied to the compressor 6b where it becomes high temperature and high pressure gas, and then, the refrigerant gas is passed through the condenser 6a. The refrigerant gas is cooled by the blower 7 at the outdoor side to be liquified.
The liquid refrigerant is fed to the cooling device 5a where evaporation of the refrigerant takes palce by taking heat from the air which has been sucked through the intake port 2a by means of the blower at the room side, and the sucked air is thereby cooled. Thus, cooling mode can be obtained by discharging the cooled air through the outlet port 2b. It is easily understood that warming of a room is carried out by reversing a flow of the refrigerant.
In the conventional air conditioning apparatus, an air communicating port (not shown) is formed in the partition plate 4 for separating the room side unit 5 from the outdoor side unit 6, and a damper for opening and closing the air communicating port is provided as an air ventilating device. The ventilation device is so constructed that air in a room is discharged to the outdoor or air in the atmosphere is sucked into a room. As an air ventilation device used for an air conditioning apparatus, there has been known, for instance, one as show in Japanese Unexamined Utility
Model Publication No. 154550/1979, in which a cable wire connected to the damper is used to cause opening and closing operations of the damper by operating a lever which is provided the other end of the wire.
In the conventional air conditioning apparatus using the above-mentioned cable wire, however, it is necessary to provide complicated wire supporter, a pivotal shaft and so on in order to assemble the cable wire because an operating section formed at the side of the front panel 2 has to be fairly away from the damper attached to the partition plate 4. With the construction, there are disadvantages such that the number of structural elements increases; assembling works become complicated; looseness of the wire tends to be produced, which hinders efficiency of productivity; there takes place elongation of the wire during long term use, and reliable opening and closing operations of the damper can not be attained. Particularly, when the damper is operated by using the wire, a user was not satisfied with the operation of the damper.
It is an object of the present invention to provide a ventillation device for an air conditioning apparatus which has a simple construction with a small number of parts, whereby the assembling operations is easy; user's feeding in operation substantially improved; opening and closing operations of a ventilation damper become reliable: and an opening or closing state of the damper can be easily observed by an operator.
The foregoing and the other objects of the present invention have been attained by providing a ventilation device for an air conditioning apparatus in which an air communicating port formed in a partition plate which separates a room side section from an outdoor side section in the interior of the air conditioning apparatus is subjected to control of opening and closing operations by an externally operated damper, characterized by comprising an opening lever supported in an air conditioning apparatus main body so as to be sladable along the longitudinal direction and pushing a damper which is moved with the inner end part of the opening lever toward the outdoor side to effect an opening operation, a closing lever slidably supported in the main body in parallel to the opening lever, a connecting member which is bridged between the opening lever and the closing lever and which has a central portion pivotally supported, whereby the opening and closing levers are moved mutually opposing directions, and a spring member exerting a force to the connecting member to cause advancing and retracting movement of the opening lever with respect to the damper, wherein the outer end parts of the opening and closing levers are at openings for operation which are formed in a front panel of the main body.

Preferred embodiments of the present invention will be described with reference to the drawings.
Figs. 1 to 6 illustrate an embodiment of the ventilation device for an air conditioning apparatus according to the present invention. In the Figres, the same reference numerals as in
Fig. 6 designate the same or corresponding parts, and therefore, description of these parts is omitted.
According to the present invention, an air communicating port 10 formed in a partition plate 4 ar a casing 8 made of material such as an insulating substrate which defines room side and outdoor units 5, 6, is opened and closed by a damper plate 11 which is operated from the outside of the air conditioning apparatus. The ventilation device comprises an opening lever 13, a closing lever 14, a connecting member 16 and a spring member 17.
The opening lever 13 is slidably supported in the longitudinal direction of the air conditioning apparatus 1 so that it extends along the inside of the side surface 12a of a substantially L-shaped electric parts fitting plate 122 which is disposed at a side of the room side unit 5. The opening lever 13 has its innermost end 1 3a which is moved in association with a the damper plate 11 so as to push it toward the outdoor side to thereby effect an opening operation.
The closing lever 14 is also slidably supported along the inside of the side surface 1 2a of the fitting plate in parallel to the opening lever 13.
The connecting member 16 is bridged between the opening lever 13 and the innermost end 14a of the closing lever 14 and has a central portion pivotally supported by a screw 15 to the side surface 1 2a of the fitting plate which constitute a stationary member. By operating the connecting member 16 clockwisely or counter-clockwisely, the both levers 13, 14 are shifted in the mutually opposed directions.
The spring member 17 is adapted to give an urging force to the connecting member 16 thereby to cause the opening lever 13 to be pushed toward the damper plate 11 and to maintain an opening or closing state of the damper plate 11.
Each of the outermost ends 13b and 14b (the end to be operated) of the opening lever 13 and the closing lever 14 is arranged to project from each operating aparture 19a or 19b fromed in the front panel 2 (actually it is formed in a cover 18 attached to the front part 1 2b of the fitting plate 12 of the air conditioning apparatus main body 1).
In the above-mentioned embodiment, the opening lever 13 is prepared separate from the damper plate 11. In this case, the damper plate 11 is usually pushed by a damper spring 20, e.g. a leaf spring, one end of which is screwed to the partition plate 4 so as to close the air communicating port. Further, a lever portion 1 1a is formed projecting from the damper plate 11 in the forward direction, i.e. toward the opening lever 13. The lever portion 11 a is slidably supported by a pair of ears 21 which are formed by cutting and raising the side surface 4a of the casing 8 and a resess formed in a leg portion 22a of a cover 22 which is placed in the rear of the electric parts fitting plate 12.When the opening lever 13 is pushed at its outermost end 13b, the damper plate 11 having the lever portion 11 a abutting on the innermost end 1 3a of the opening lever 13 is moved against the spring action of the spring 20 to open the air communicating port. When a force applied to the outermost end 1 3b of the opening lever is released, the damper plate 11 is moved to close the air communicating port 10 by the action of the spring 20. In Fig. 1, a reference numeral 11 b designates an engage pin projecting from the reverse side surface of the damper plate 11 and a numeral 20a designates an engage hole formed in the damper spring 20 to be engaged with the engage pin 1 1b.
In Fugure 3, a blower 23 at the room side is connected to a shaft of a driving motor 24 which drives the blower 7 at the outdoor side. When the driving motor is actuated, a part of air sucked by the blower 23 is supplied to the outdoor side unit 6 if the air communicating port 10 is opened, an air is also sucked by the blower 7 at the outdoor side; thus, discharge operation of air is carried out.
The damper lever according to the present invention is so constructed that the opening lever 13 and the closing lever 14 are connected by a T-shaped connecting member 16 to perform associated movement as shown in
Figs. 4a, 4b and Fig. 5. The construction of the opening and closing levers will be described in detail. The opening and closing levers 13, 14 each has a cranked portion 13c or 1 4c which is formed at the intermediate portion of each of the opening and closing levers so that their inner end parts are away from and in parallel to each other. Engaging pins 30a, 30b are formed respectively in the opening and closing levers at the elongated portions which extends in a mutually separated fashion.On the other hand, elongated holes 31a, 31b are formed at both end of the transversely extending portion of the T-shaped connecting member 16, and the elongated holes 31a, 31b are engaged with the engaging pins 30a, 30b. A central hole is formed near the jointed portion of the transversely extending portion and the leg portion perpendicular to the transversely extending portion in the- Tshaped connecting member 16. The connecting member 16 is pivotally supported by inserting a screw into a threaded hole 15a so that the connecting member 16 is turnably held by the side surface 12a of the fitting plate as a stationary member, whereby the opening and closing levers 13, 14 are operated in association with each other.The reason why the engaging holes 31a, 31b are formed in an elongated form as shown in
Figs. 4a, 4b is that a mutually smooth operations of the levers 13, 14 can be performed, and errors which may take place in manufacturing structural elements can be absorbed.
In this embodiment, linearly extending portions are formed in the opening and closing levers 13, 14 at positions before the cranked portions 13c, 14c, and a substantially Lshaped gripper 34 is extended from the opening lever 13 to the lower surface of the closing lever 14 which is formed at the opposite side of the sliding surfaces of the levers 13, 14, whereby they can be assembled in a mutually slidable condition.
In Fig. 1, projections 35 are formed in the sliding surface between the opening and closing levers 13, 14 so that the sliding movement of the both levers is performed with the minimum frictional force when the levers are operated. The projections may be provided in the inner surface of the gripper 34 to hold the closing lever 14.
In the embodiment of the present invention, a spring member 1 7 is extended between the leg portion of the T-shaped connecting member 16 and the side surface 12a of the fitting plate 12 so that the levers 13, 14 undergo a related movement to thereby control of the damper. A coil spring is used as the spring member 1 7 and one end of the linearly extended portion of the coil spring is engaged with an engaging piece 32 which is formed by cutting and knocking the leg portion of the connecting member 16. The other end of the linearly extending portion of the coil spring 17 is connected to another engaging piece 33 formed in the side surface 1 2a of the fitting plate as a stationary member.A pushing force by the spring 1 7 to operate the opening lever 13 toward the side of the damper is imparted by arranging the spring 17 in such a manner that an engaging point of the spring 17 at the side of the connecting member 16 (a movable side engaging point C of the spring fixed by the engaging piece 32) is moved beyond a line (a) extending from a turning center A determined by the screw 15 fastened to the connecting member 16 to a stationary side engaging point B of the spring 1 7 which is fixed by the engaging piece 33 (see Fig. 11).
With the construction, the spring 1 7 exerts an urging force to the connecting member 16 in the direction opposite the original position. In
Figs. 4a, 4b, a reference numeral 1 7a designates an end of the spring 17 fixed by the engaging piece 32 which constitues the movable side engaging point C and a reference numeral 1 7b designates the other end of the spring 17 fixed by the engaging piece 33 formed by cutting and raising a part of the side surface 12a of the fitting plate which constitues the stationary side engaging point
B. The arrangement of the spring 17 with respect to the connecting member 16 enables operations such that the connecting member 16 causes the damper plate 11 to be in an opening state or a closing state, the both states being maintained unless the spring 17 is further operated.
The operation of the spring 17 is detailedly explained with reference to Figs. 4a, 4b and
Figs. lia, lib. Figs. 11a and lib shows a condition of the coil spring 17 in which the stationary side engaging point B is shifted by a distance x with respect to a line (a) extending from the turning center A of the connecting member 16 to the direction in parallel to the opening lever 13. Accordingly, when the damper is in an opening state, a vector a in proportional to the distance y acts on the connecting member to maintain the opening state of it, namely the vector causes the connecting member 16 to turn clockwisely with respect to the movable side supporting point
C.On the other hand, when the damper closes the air communicating port, a vector ss in proportional to a distance z causes the connecting member 16 to be in the closing state, namely the direction for turning the connecting member 16 counter-clockwisely. In this construction, the magnitude of the vector a is different from that of the vector ss because the stationary side supporting point B is shifted by x. Accordingly, an operational force required to operate the opening lever 13 is different from that of the closing lever 14. The reason is as follows. It is necessary to provide a force against the pressing force of the damper spring 20 which acts on the damper plate 11 when the damper plate is operated to open by pushing the opening lever 13.On the other hand, the spring force of the damper spring 20 functions to assist the operation of the closing lever 14. As a result, operational forces for the both levers 13, 14 become unbalanced. Therefore, by it is possible to eliminate such unbalanced state by shifting the distance x so as to make one vector different from the other. In other words, the engaging point B is shifted by x from the line (a) so that a pushing force and a returning force caused by the opening and closing levers 13, 14 are balanced.
In this embodiment, the spring-engaging piece 33 at the fixed side which engages the other end 17b of the spring 17 is formed to have a predetermined inclination so as to hold the side portion of the spring 17 (Fig. 12) when the connecting member 16 is subjected to the opening operation as shown in Fig. 4a, and further, the other end 17b of the spring 17 is formed in a crank form. With such construction, it is possible to prevent a trouble of the spring 17 coming off from the spring-engaging piece 33 to thereby maintain a smooth spring action even though the levers are repeatedly operated, and to improve efficiency of work.Nemely, the coming off of the spring 17 can be prevented by forming the other end 17b of the spring 17 in a crank form, and a problem of coming off or faulty movement of the spring 17 can be eliminated by the spring engaging piece 33 which is formed to have an inclination so that the side portion of the spring 17 is in contact with the engaging piece 33 at the operating time.
The construction of the operating means for the opening and closing levers 13, 14 according to the present invention is not limited to that shown in Figs. 4a, 4b, but it is possible to modify the shape and construction of each parts as desired. For instance, the same function and effect can be attained by contriving the driving means in such a manner that as shown in Figs. 13a, 13b and 14a, 14b an end of the spring 17 connected to the connecting member 16 is shifted by a distance I from the center line of the engaging piece 32 which extends in the longitudinal direction of the leg portion of the connecting member 16, while the stationary side engagaing point D at which the other end of the spring 17 is fixed is positioned on a line (a) which is extended from the turning center A.In this case, it is understandable that a vector 7 in proportional to a distance m is exerted to the point E when the damper is in an opening state, while a vector which is smaller than the vector a is exerted to the point E with a magnitude in proportional to a distance n when the damper is in a closing state.
Another feature of the present invention will be described with reference to Figs. 1 to 5.
In the ventilation device of the present invention, the opening and closing levers 13, 14 as a damper lever means, are slidably supported in the longitudinal direction along the side surface 12a of the electric parts fitting plate 12 made of a metallic plate so as to operate the damper at the air communicating port 10. The opening and closing levers 13, 14 have their outermost ends 13b, 14b at the operating openings 19a, 19b formed in the cover 18 which is provided at the side of the front panel 2. A stepped portion 38 is formed in the fitting plate 12 by bending it in the direction perpendicular to the longitudinal direction of the levers 13, 14 and in the direction away from these levers. Further, stopper pieces 37a, 37b are formed at one side surface of each of the levers 13, 14 so that the stopper pieces impinge the stepped portion 38 of the side surface 12a to restrict the movement of the levers 13, 14 toward the air communicating port.
According to the present invention, an operating stroke of the opening and closing levers 13, 14 can be suitably provided and an impinging sound is caused between the stepped portion 38 formed by bending the fitting plate 12 and the stopper pieces 37a, 37b provided in the side surface of the levers, whereby an operator can recognize by the impinging sound that opening or closing operation has certainly been carried out.
In the embodiment of the present invention, the opening and closing levers 13, 14 are each provided with a flange-like stopper 36a or 36b near each of the outermost ends 13b, 14b. The flange-like stoppers 36a, 36b are formed in the opening and closing levers 13, 14 as well as with the stopper pieces 37a, 37b projecting toward the bent portions 13c, 14c by molding operations. The flange-like stoppers 36a, 36b and the stopper pieces 37a, 37b are adapted to alternately impinge the inner side surface of the cover 18 attached to the front part 1 2b of the fitting plate or the stepped portion 38 of the side surface 1 2a of the fitting plate as shown in
Figs. 1 and 5.With the above-mentioned construction, operating strokes of the levers 13, 14 are certainly provided in the both directions, and a click sound produced when the stoppers impinge the surface or stepped portion of a metallic plate can be utilized.
According to the ventilation device of the present invention having the above-mentioned construction, a pushing force to the opening lever 13 causes movement of the damper plate 11 toward the outdoor side unit against the spring action of the damper spring 20, whereby the air communicating port 10 is opened, and air in a room is discharged to the atmosphere. At the moment, the closing lever 14 is kept in a condition with the outermost end 14b projecting outside, while the opening lever 13 is kept in the condition with the outermost end projecting outside; however the quantity of projection of the opening lever being smaller than that of the closing lever 14.
Accordingly, an operator can easily recognize the condition of the levers, i.e. opening or closing condition of the damper.
When the closing lever 14 is pushed, the opening lever 13 is moved toward the room side 5, namely, the front side of the air conditioning apparatus main body 1 by the action of the connecting member 16 with the consequence that the opening lever is moved away from the damper 11, whereby the damper plate 11 is operated to close the air communicating port 10 by the action of the damper spring 20. In this case, since the opening lever 13 is prepared separately from the damper plate 11, reliable closing operation can be obtained for the air communicating port even in closing operation of the damper.
In a case that the opening lever 13 constituting a damper lever is prepared separately from the damper plate 11 for opening and closing the air communicating port 10, there is a great advantage that the fitting plate 12 in which electrical parts are attached can be easily removed to be repaired without removing the damper plate.
In the foregoing embodiment, description has been made to the case that the opening lever 13 with the outermost end 13b and the closing lever 14 with the outermost end 14b are vertically arranged in a parallel relationship.
However, it is possible to juxtapose the levers 13, 14 in a lateral position. In this case, an end of either lever is bent to be in an L-shape and an operating end formed at that end of the lever which is in parallel to the other lever.
The above-mentioned construction can be modified as follows. For instance, as shown in
Figs. 7 and 8, the opening lever 13 is formed integrally with the damper plate 11, or as shown in Figs. 9 and 10, the opening lever 13 is connected to the damper plate 11 by means of a fastener such as a screw 40 and an elongated hole 41. In the former case, the spring for pressing the damper and other structural elements can be removed to reduce number of parts, which improves efficiency of assembling work. In the later case, reliable opening and closing operations of the damper, especially, the closing state can be preferably maintained.
In the several embodiment as above-mentioned, description has been made as to the ventilation device used for opening and closing the air communicating port at the air-discharging side in an air conditioning apparatus. However, the present invention allows use of the ventilation device to open and close the air communicating port at the air-sucking side.
Further, the ventilation device of the present invention is applicable to another type of air conditioning apparatus.
As described above, in accordance with the ventilation device for an air conditioning apparatus according to the present invention, the connecting member is used to move the opening and closing levers in mutually opposite directions. Accordingly, the following various advantages can be obtained. Construction of the device is simple and is manufactured at a low cost; excellent feelings are given to an operator when he open or close the ventilating damper; reliable opening and closing operations of the damper can be obtained while easiness of the operation is provided; leakage of air which was a problem in the conventional device can be improved; an operator can easily observe the condition of the damper in an opening or closing state; and efficiency of assembling operations is improved.
