the second cam portion is disposed opposite to the inside of the chamber of the first cam portion, and moves in a direction away from the first cam portion when the operation plate is rotated in a closing direction against the spring by wind pressure.
According to the above configuration, although the function of closing by wind pressure and the function of opening and closing by manual operation are provided, only one work board is required.
Preferably, the coupling mechanism includes a first engaging portion disposed on the slider and a second engaging portion protruding from the operating plate in an indoor direction, and the first engaging portion and the second engaging portion are coupled so as to be movable relative to each other in a direction orthogonal to a sliding direction of the operating plate and so as not to be movable relative to each other in the sliding direction.
According to the above configuration, the configuration of the coupling mechanism can be simplified.
Preferably, the spring is disposed between the first engaging portion and the second engaging portion.
According to the above configuration, the spring moves along with the sliding of the operating plate, and therefore, the force of the spring can be reliably transmitted to the operating plate. Further, since the force of the spring is transmitted to the operating plate by using the coupling mechanism, the configuration for transmitting the force can be simplified.
More preferably, the first engaging portion has a housing space in which the second engaging portion is inserted and the spring is housed, and the spring is formed of a tension coil spring having one end hooked to the first engaging portion and the other end hooked to the second engaging portion.
According to the above configuration, the configuration for transmitting the force of the coupling mechanism and the spring can be further simplified.
Preferably, the first cam portion has a cam surface facing the operating plate, and the second cam portion is constituted by an abutting portion projecting from the operating plate in the outdoor direction and contacting the cam surface.
More preferably, the cam mechanism is disposed in the vicinity of the shaft portion.
According to the above configuration, the operating plate can be opened and closed with a relatively small displacement of the second cam member.
In one specific aspect of the present invention, the first engaging portion is constituted by an engaging block independent from the slider, the engaging block is supported by the slider so as to be slidable in the sliding direction, a shape memory alloy spring and a biasing spring that urge the engaging block in the sliding direction in opposite directions to each other are provided in the slider, and the temperature responsive actuator is constituted by the engaging block, the shape memory alloy spring, and the biasing spring.

As shown in fig. 5, a convex portion 42a is formed on the upper and lower surfaces of the engaging block 42, and the convex portion 42a is inserted into a long hole (engaging hole) 41y formed in the upper and lower plate portions of the slider body 41 a. Since the engaging hole 41y has a larger dimension in the sliding direction of the operating plate 20 than the protruding portion 42a, the engaging block 42 is supported to be slidable in the sliding direction of the operating plate 20 with respect to the slider 41. The convex portion 42a and the elongated hole 41y are provided as a limiting mechanism for determining the stroke and the left and right movement limit positions of the engaging block 42 with respect to the slider 41.
As shown in fig. 7 and 8, the shape memory spring 43 applied between the engaging block 42 and the right spring holder 41b urges the engaging block 42 in the right direction. The biasing spring 44 interposed between the engaging block 42 and the left spring holder 41c biases the engaging block 42 in the left direction.
As shown in fig. 5 and 7, the engagement block 42 has a housing space 42 b. On the other hand, an engaging projection 50 (second engaging portion) is fixed to the indoor side surface of the intermediate portion in the longitudinal direction of the operating plate 20, and this engaging projection 50 enters the housing space 42b through one of the ventilation ports 14 of the partition wall 13. The engaging projection 50 is in contact with both side surfaces of the housing space 42b, and inhibits relative movement of the engaging projection 50 with respect to the engaging block 42 in the left-right direction (movement in the sliding direction of the operating plate 20 and the slider 41), and allows relative movement in the indoor and outdoor directions (the direction orthogonal to the sliding direction).
The engaging block 42 and the engaging projection 50 constitute a coupling mechanism M for coupling the slider 41 and the operating plate 20.
The spring 55 is accommodated in the accommodating space 42b of the engaging block 42. The spring 55 is a tension coil spring, and one end thereof is hooked to the bottom of the engaging block 42, and the other end thereof is hooked to the indoor end of the engaging projection 50 in a state inserted into the slit 50a of the engaging projection 50. The operation plate 20 is biased in the opening direction by a spring 55.
As shown in fig. 4, 5, and 8, the ventilation device 7 further includes a plurality of, for example, two cam mechanisms 60 arranged at intervals in the longitudinal direction of the device body 10. These cam mechanisms 60 are disposed in the vicinity of the shaft portion 21 (at a position closer to the shaft portion 21 in the width direction of the operating plate 20) on the outdoor side than the operating plate 20 in the outdoor space 15.
Each cam mechanism 60 includes a cam member 61 (first cam portion) made of resin fixed to the apparatus main body 10 and a contact member 62 (second cam portion) made of resin fixed to the protruding piece 24 of the operating plate 20 as a cam follower.
The cam member 61 has a fixing portion 61a fixed to the lower surface of the upper wall 11 of the apparatus body 10, and a hanging portion 61b hanging from the fixing portion 61 a. A surface of the hanging portion 61b facing the operating plate 20 is provided as a cam surface 61 c. As shown in fig. 8, the cam surface 61c has a central portion 61x farthest from the operating plate 20 and left and right end portions 61y closest to the operating plate 20, and inclined portions 61z between the central portion 61x and the left and right end portions 61 y. The central portion 61x extends linearly in the longitudinal direction of the apparatus body 10 and has a predetermined length. In the present embodiment, only the central portion 61x, the left inclined portion 61z, and the left end portion 61y are used.
As shown in fig. 6 and 8, a pair of notches 24a are formed in the protruding piece 24 of the operating plate 20, and a contact member 62 is attached to a portion where the protruding piece 24 remains between the notches 24 a. The notch 24a is formed to avoid interference with the cam member 61.
Since the operating plate 20 is biased in the opening direction by the spring 55, the contact member 62 is brought into contact with the cam surface 61c of the cam member 61 by the force of the spring 55.
The front end edge of the contact member 62 extends linearly in the longitudinal direction of the operating plate 20. The contact member 62 has a longitudinal direction substantially equal to the longitudinal dimension of the central portion 61x of the dimension cam surface 61 c. The contact member 62 has a cross-sectional shape of a front end edge thereof in an arc.
As shown in fig. 3 and 9, the ventilation device 7 further includes a manual operation mechanism 70 provided at the left end portion of the device body 10. To describe in detail, one end of the link 71 is coupled to the left spring holder 41c of the slide unit 40, and the operation lever 72 (operation member) is rotatably coupled to the other end of the link 71.
On the other hand, a holder 75 is fixed to the apparatus main body 10. The holder 75 has a support hole 75a formed substantially at the center, a finger insertion recess 75b formed at the left, and a spring holding portion 75c formed at the right. A leaf spring 76 having a mountain shape is attached to the spring holding portion 75 c. The link 71 is formed with two recesses 71a and 71b that accommodate the top portion of the center of the leaf spring 76.
The operating lever 72 is exposed to the indoor side through a support hole 75a of the holder 75, and is supported to be rotatable about the support hole 75a between an open operating position and a closed operating position. In the open operation position, as shown in fig. 9, the operation lever 72 is fallen down along the operation body 10. When a finger is put into the finger insertion recess 75b of the holder 75 and hooked on the operation lever 72 and the operation lever 72 is pulled up as indicated by an arrow a, the operation lever 72 reaches the closing operation position. In this process, the coupling portion between the operating lever 72 and the link 71 moves in the left direction as indicated by the arrow B, and the slide unit 40 slides in the left direction in association therewith.
The open operation position and the close operation position of the operation lever 72 are maintained by the top of the leaf spring 76 being selectively fitted into the recesses 71a and 71b of the link 71.
As shown in fig. 1, the cover plate 8 is formed with an operation hole 8b for exposing the operation lever 72.
The operation of the ventilator 7 having the above-described configuration will be described.
When the operating lever 72 of the manual operating mechanism 70 is located at the opening operating position shown in fig. 9, the slider 41 of the slide unit 40 is located at the rightmost side. In this position, the temperature sensitive actuator 49 automatically controls the opening and closing of the operating plate 20 in accordance with the air temperature.
When the air temperature is high, the shape memory spring 43 has a strong spring force, and therefore the engagement block 42 is positioned furthest to the right with respect to the slider 41. Further rightward movement of the engagement block 42 is restricted by the contact of the convex portion 42a of the engagement block 42 with the right end of the elongated hole 41y of the slider body 41 a.
As described above, when the slider 41 is positioned rightmost with respect to the apparatus body 10 and the engagement block 42 is positioned rightmost with respect to the slider 41, the contact member 62 of the operating plate 20 biased in the opening direction by the spring 55 comes into contact with the central portion 61x of the cam surface 61c of the cam member 61 as shown in fig. 4A. As a result, the operating plate 20 is located at the fully open position farthest from the partition wall 13.
When the temperature drops to below 18 ℃, for example, the elastic force of the shape memory spring 43 is weakened and the force of the biasing spring 44 is relatively increased compared to the shape memory spring 43, so that the engaging block 42 slides in the left direction with respect to the slider 41. As the engaging block 42 slides, the operating plate 20 slides in the same direction through the engagement between the engaging block 42 and the engaging projection 50. As the operating plate 20 slides, the contact member 62 moves from the central portion 61x of the cam surface 61c to the inclined portion 61 z. As the air temperature decreases, the contact member 62 travels leftward while contacting the inclined portion 61 z. Therefore, the operating plate 20 gradually approaches the partition wall 13, and the opening degree thereof decreases.
When the atmospheric temperature further decreases to reach, for example, 12 ℃, the contact member 62 is positioned at the middle portion of the inclined portion 61z, and the opening degree of the operating plate 20 reaches the position 1/3 at the time of full opening as shown in fig. 4B. At this time, since the convex portion 42a of the engaging block 42 is locked to the left end of the elongated hole 41y of the slider body 41a, even if the atmospheric temperature is further lower than 12 ℃, the engaging block 42 is prevented from sliding further in the left direction, and the operating plate 20 does not reach a position (full-close position) at which the scavenging port 14 is completely closed, but can maintain the opening degree of 1/3.
When the automatic opening/closing control of the work board 20 is performed according to the air temperature as described above, when strong wind pressure is applied to the work board 20 from the outside, the work board 20 rotates in the closing direction against the force of the spring 55. As a result, the operating plate 20 reaches the fully closed position shown in fig. 5B from the fully open position shown in fig. 5A or the open position corresponding to the air temperature, and the ventilation port 14 is completely closed by the contact of the seal 30 with the partition wall 13. This can prevent the intrusion of wind and rain into the room even when the occupant goes out. In addition, excessive ventilation in strong wind can be prevented.
During the closing operation by the wind pressure of the operating plate 20, the contact member 62 is separated from the cam surface 61c of the cam member 61, and therefore the cam mechanism 60 does not hinder the closing operation of the operating plate 20.
Even if the operation plate 20 strongly abuts against the partition wall 13, the impact sound can be absorbed by the sound absorbing pad 35 provided on the operation plate 20.
Even when the occupant operates the air conditioner to adjust the room temperature or during a storm, the operation panel 20 can be intentionally closed by manual operation. Specifically, the operating lever 72 of the manual operating mechanism 70 is raised to bring the operating lever 72 into the closed operating position. Thereby, the slider 41 slides a predetermined distance in the left direction. During this sliding, the right end of the elongated hole 41x of the slider body 41a abuts against the convex portion 42a of the engagement block 42, so that the engagement block 42 moves in the left direction together with the slider 41. The sliding distance of the slider 41 is longer than the distance from the left end of the central portion 61x of the cam surface 61c to the left end portion 61 y. As a result, even when the operating plate 20 is at the fully open position (i.e., even when the air temperature is high, the engagement block 42 is positioned at the rightmost side, and the abutment member 62 is positioned at the central portion 61x of the cam surface 61 c), the abutment member 62 can be reliably moved to the left end portion 61y of the cam surface 61c, and the operating plate 20 can be brought to the fully closed position.
Further, when the air temperature is low, for example, when the engagement block 42 is positioned leftmost with respect to the slider 41 and the abutment member 62 is positioned on the inclined portion 61z of the cam surface 61c (when the operating plate 20 is positioned at 1/3 at the open position), if the lever 72 is set to the closed operation position, the right end of the elongated hole 41y of the slider body 41a abuts against the convex portion 42a of the engagement block 42 in the middle of the sliding of the slider 41, and the engagement block 42 can be moved leftward together with the slider 41, and the operating plate 20 can be set to the fully closed position in the same manner as described above.
Next, a second embodiment of the present invention will be described with reference to fig. 10 to 14. In the second embodiment, the components corresponding to the first embodiment are not shown, or the same reference numerals are given to the drawings, and detailed description thereof will be omitted. In the description of the components not shown in fig. 10 to 14, the same reference numerals as those in the first embodiment are used.
In the present embodiment, the slide unit 40A includes a slider 41, a moving block 45 (moving member) provided to the slider 41, an engaging block 47 (first engaging portion), a shape memory spring 43, and a biasing spring 44.
The moving block 45 is supported slidably in the longitudinal direction of the slider body 41 a. The moving block 45 has a pair of left and right side plates 45a and a bridge portion 45b connecting the pair of side plates 45a at upper and lower ends. The moving block 45 has a rectangular hollow frame shape elongated vertically when viewed from the front. As shown in fig. 13, a hook portion 45c to which one end of the shape memory spring 43 is hooked is formed on the outer surface of the right side plate 45a, and a hook portion 45d to which one end of the bias spring 44 is connected is formed on the outer surface of the left side plate 45 a.
A cam member 81 (third cam portion) extending in the left-right direction is provided across the inner surfaces of the intermediate portions of the pair of side plates 45 a. The upper surface of the cam member 81 is provided as a cam surface 81 a. The cam surface 81a has a left lowermost portion 81x extending horizontally, an inclined portion 81y extending obliquely upward and continuing to the right end of the lowermost portion 81x, and an uppermost portion 81z continuing to the right end of the inclined portion 81 y.
The engagement block 47 has a pair of left and right side plates 47a and a pair of upper and lower plates 47b, and has a hollow frame shape of a rectangular shape elongated in front view, and a housing space 47 c.
The engaging block 47 has a convex portion 47d on its upper and lower surfaces, and the convex portion 47d is fitted into the engaging hole 41z of the slider body 41 a. In the present embodiment, since the protruding portion 47d and the engagement hole 41z have substantially the same size, the engagement block 47 is fixed so as not to be movable with respect to the slider body 41 a.
The engaging block 47 is narrower than the width of the moving block 45, and is housed in the internal space of the moving block 45. The left and right side plates 45a of the moving block 47 abut against the left and right side plates 47a of the engaging block 45 fixed to the slider body 41a, thereby restricting the stroke of the sliding of the moving block 45.
A concave portion 47e through which the cam member 81 passes is formed in the side plate 47a of the engagement block 47.
A pin 47g to which the lower end of the spring 55 is hooked is attached to the lower plate 47b of the engagement block 47.
The engaging projection 51 (second engaging portion) fixed to the indoor side surface of the operating plate 20 is accommodated in the accommodating space 47c of the engaging block 47, and thus relative movement of the engaging projection 51 in the left-right direction (sliding direction) with respect to the engaging block 47 is prohibited, and relative movement in the direction orthogonal to the sliding direction is permitted.
A pin 51a to which the upper end of the spring 55 is hooked is attached to an indoor end of the engaging projection 51.
The lower surface of the portion of the engaging projection 51 on the indoor side is provided as an abutting portion 82 (fourth cam portion) that contacts the cam surface 81a of the cam member 81 of the moving block 45. The cam member 81 and the contact portion 82 constitute a second cam mechanism 80.
In the present embodiment, the temperature responsive actuator is configured by the moving block 45, the shape memory spring 43, the biasing spring 44, and the second cam mechanism 80.
In the above configuration, when the operating lever 72 of the manual operating mechanism 70 is located at the open operating position shown in fig. 9, the slider 41 of the slide unit 40 is located at the rightmost side. In this state, the contact portion 62 of the cam mechanism 60 is located at a position facing the central portion 61x of the cam surface 61 a. The contact portion 62 may be in contact with the central portion 61x or may be slightly spaced apart from the central portion.
When the air temperature is high, the elastic force of the right shape memory spring 43 is strong, and therefore the moving block 45 is positioned furthest to the right with respect to the slider 41. Further rightward movement of the moving block 45 is restricted by the contact of the left side plate 45a of the moving block 45 with the engaging block 47.
When the moving block 45 is positioned on the rightmost side with respect to the slider 41, the contact portion 82 of the engagement projection 51 of the operating plate 20 biased in the opening direction by the spring 55 contacts the lowermost portion 81x of the cam surface 81a of the cam member 81 as shown in fig. 10A and 14. As a result, the operating plate 20 is located at the fully open position farthest from the partition wall 13.
When the temperature drops to below 18 ℃, for example, the elastic force of the shape memory spring 43 is weakened and the force of the biasing spring 44 is relatively increased compared to the shape memory spring 43, so that the moving block 45 slides in the left direction with respect to the slider 41. As the moving block 45 slides, the contact portion 82 of the engaging projection 51 moves from the lowermost portion 81x of the cam surface 81a to the inclined portion 81 y. As the air temperature decreases, the contact portion 82 moves rightward relative to the cam surface 81a while contacting the inclined portion 81 y. As a result, the contact portion 82 is pushed up by the cam surface 81a, and the operating plate 20 rotates so as to gradually approach the partition wall 13, and the opening degree thereof decreases. As the operating plate 20 rotates, the contact portion 62 moves in a direction away from the cam surface 61 a.
When the air temperature further decreases to, for example, 12 ℃, the contact portion 82 reaches the uppermost portion 81z of the cam surface 81a, and the opening degree of the operating plate 20 reaches the position 1/3 open as shown in fig. 10B. At this time, since the right side plate 45a of the moving block 45 abuts on the engaging block 47, even if the atmospheric temperature is further lower than 12 ℃, the moving block 45 is prevented from sliding further in the left direction, and the operating plate 20 can be maintained at 1/3 degrees of opening without reaching a position (full-close position) at which the scavenging port 14 is completely closed.
In the present embodiment, as described above, the opening degree of the operation plate 20 can be automatically controlled by simply rotating the operation plate 20 without sliding the operation plate 20, and therefore, the load on the temperature-sensitive actuator can be reduced.
The fully closing operation of the operating plate 20 in strong wind is the same as that in the first embodiment, and therefore, the description thereof is omitted.
The action of forcibly closing the operation plate 20 by the operation lever 72 is similar to that of the first embodiment. However, in the present embodiment, the slider 41 and the operating plate 20 are coupled via the engaging block 47 and the engaging projection 51 so as not to be able to move relative to each other in the sliding direction, and therefore, the operating plate 20 can be slid while the slider 41 slides, regardless of the opening position of the operating plate 20 depending on the air temperature.
The present invention is not limited to the above embodiments, and various embodiments can be realized.
The function of automatically opening and closing the operation panel according to the air temperature may be omitted. For example, in the first embodiment, the shape memory spring and the biasing spring may be omitted, and the engaging block (first engaging portion) may be fixed at a predetermined position of the slider. In this case, the manual operation mechanism directly adjusts the slide position of the work plate via the slider and the coupling mechanism, and the opening degree of the work plate can be controlled very finely.
The operating member of the manual operating mechanism may be configured to slide with respect to the apparatus main body.
In the case of using the temperature sensitive actuator, the operation plate may be fully closed when the air temperature is low.
In the cam mechanism, a cam member (second cam member) having a cam surface facing the outside of the room may be provided on the operating plate, and a contact member (first cam member) that contacts the cam surface may be provided on the apparatus main body.
The ventilation device of the present invention can be assembled not only to a fixed and embedded window frame but also to an openable and closable window frame and a sliding door frame (japanese patent No. サッシ ).
Industrial applicability of the invention
The present invention can be applied to a ventilation device that can be automatically closed in strong wind and can be manually opened and closed.
