The present applicant is considering the use of the above automatically adjustable ventilation device in the double glazing used in the cold district.

The double glazing has a shielding structure on the outdoor side and a shielding structure on the indoor side, and an insulation space is formed between both shielding structures. Each of these shielding structures is comprised by two slidable chassis doors, for example.

When using a ventilation apparatus for the said double window, it is necessary to provide the said ventilation apparatus in both the outdoor structure and the indoor shielding structure. Therefore, when the outdoor side shielding structure and the indoor side shielding structure were tested using the ventilation apparatus of the same specification and the same temperature characteristic, the heat insulation effect of a double window fell to the unexpected level.

When the cause of the fall of the heat insulation effect of the said double glare was investigated, the following facts turned out. That is, the outdoor ventilator operates in response to the outdoor temperature, while the indoor ventilator operates in response to the temperature of the adiabatic space. Because the temperature of this heat insulation space is higher than the outdoor temperature in the winter season, if the ventilation apparatus of the said outdoor side and the indoor side is the same standard (in other words, if the temperature characteristics of both ventilation apparatuses are equal), The opening area of the ventilation passage became larger than the opening area of the ventilation apparatus on the outdoor side, which caused an unexpected decrease in the thermal insulation effect.

According to this, the ventilation device on the outdoor side and the indoor side can be made to the same standard (same structure) except for the temperature characteristic of the elastic body made of the shape memory alloy, and the manufacturing cost can be reduced.

Preferably, each ventilator extends horizontally, the apparatus main body and the working plate are formed to be thin and long, and the elastic body and the bias elastic body made of the shape memory alloy are made of a tension coil spring, respectively on both sides of the movable body. While being disposed, the elastic force of the elastic body made of the shape memory alloy decreases as the temperature decreases, so that the temperature sensitive actuator reduces the operating plate in the direction of reducing the opening area.

The pair of chassis doors 5A and 5A on the outdoor side are arranged to the left and right as shown in FIG. 2, so that the opening divided by the window frame 4 is closed, thereby forming the closed structure on the outdoor side. Similarly, the pair of chassis doors 5B and 5B on the indoor side also form a closed structure on the indoor side in a closed state. As shown in FIG. 1, FIG. 3, the heat insulation space 6 is formed between the pair of chassis doors 5A and 5A of the outdoors side in these closed states, and the pair of chassis doors 5B and 5B of the indoor side. do.

As shown in Figs. 1 to 3, a ventilator 8A is provided on one of the pair of chassis doors 5A and 5A on the outdoor side, and the pair of chassis doors 5B and 5B on the indoor side is provided. On one side, a ventilation device 8B is provided.

In principle, the fan 3 is always in operation, and the ventilators 8A and 8B automatically control the flow of air in accordance with the air temperature. In the state where the chassis doors 5A and 5A are closed and the chassis doors 5B and 5B are closed and the ventilators 8A and 8B allow the flow of air, as indicated by arrows in FIG. A small amount of air is supplied to the indoor space 1c of the house 1 through the ventilation devices 8A, 8B and the adiabatic space 6, and contaminated air of the indoor space 1c is sucked into the fan 3 It is discharged to the outdoors.

As shown in FIG. 3, the ventilators 8A and 8B are inserted between the upper door frame 5a and the double glass 5d of the chassis doors 5A and 5B, respectively, and are horizontal along the upper door frame 5a. Is extended.

Next, the ventilation devices 8A and 8B will be described in detail. These ventilators 8A and 8B have the same structure and the same standard except for the temperature characteristic described later. Therefore, the ventilator 8A on the outdoor side will be described, and the description of the ventilator 8B on the indoor side is omitted.

As shown in Figs. 4A and 5A, the ventilator 8A is a main component and has a device body 10 (hereinafter simply referred to as a main body) extending horizontally and elongated as a main component, and an elongated operation in the same direction. The board 20 and the temperature sensitive actuator 30 (henceforth simply called an actuator) which automatically rotate this operation plate 20 according to the temperature of an outdoor side are provided.

The main body 10 assembles three aluminum mold members 11 to 13 and a resin heat insulating mold member 14, and caps are formed at both ends of the mold members 11 to 14 as shown in Fig. 4A. It is comprised by providing 15.

The upper end portions 11a and 12a forming the vertical members 11 and 12 are fitted into the recesses 5y formed in the lower part of the upper door frame 5a of the chassis door 5A shown in FIG. The double glass 5d is sandwiched between the lower end portions 11b and 12b forming the vertical members 11 and 12.

A plurality of vents 11x, 12x, 13x, 14x are formed on the vertical wall of the mold members 11 to 13 and the heat insulating member 14 at intervals in the longitudinal direction, respectively, and these vent holes 11x to 14x. ) And the ventilation passage 16 is formed in the inner space surrounded by the mold members 11 to 14 and the cap 15.

In addition, the vertical wall of the shape member 12 in which the said vent 12x is formed is called the circumferential wall 12c below.

In this embodiment, the holder 19 which attached the filter 18 to the shape | molding material 11 located in the indoor side is detachably attached. The filter 18 covers the vent 11x. A vent 19x is also formed in this holder 19.

As shown in FIGS. 5A and 5B, the operating plate 20 is accommodated in the ventilation passage 16. The upper rim of the operation plate 20 has a rotary motion shaft portion 21 having a circular cross section, and the rotary motion shaft portion 21 is accommodated in the support groove 12y formed at the upper end of the main wall 12c of the shape member 12. It is. As a result, the operating plate 20 is rotatably movable and supported by the main body 10. The operating plate 20 approaches or is spaced apart from the circumferential wall 12c of the shape member 12 according to the rotational motion. The inclination angle with respect to the circumferential wall 12c of the operating plate 20 substantially determines the opening area of the ventilation passage 16.

As best shown in FIG. 4B, a coupling hole or a coupling notch 22 is formed in the vicinity of one end (right side as viewed from the inside of the operating plate 10).

At a position proximate to the right side from the center of the lower edge portion of the operating plate 10, one projection 23 provided as a cam follower for the moving cam is formed.

In the vicinity of the left end of the operating plate 10, a projection 24 provided as a cam follower for a fixed cam and a projection 25 for restricting rotational movement are formed.

The said actuator 30 is accommodated in the ventilation path 16, and is arrange | positioned in the vicinity of the vent 13x of the shape member 13 of the said outdoor side.

As shown in FIG. 6A, the actuator 30 includes an elongated holder 31 extending in the longitudinal direction of the main body 10 and a spring 32 made of a shape memory alloy (elastic material). And a bias spring 33 (bias elastic body) composed of a tension coil spring, and a moving cam member 34 (moving body). Hereinafter, the said spring 32 made from shape memory alloy is simplified, and is called a shape memory spring.

The said holder 31 is comprised by connecting two members, and the said movable cam member 34 is slidably supported in the longitudinal direction in the intermediate position. The shape memory spring 32 and the bias spring 33 are dividedly disposed at both sides of the movable cam member 34 and extend linearly along the longitudinal direction of the holder 31. In this embodiment, the shape memory spring 32 is arrange | positioned at the left side, and the bias spring 33 is arrange | positioned at the right side. One end of these springs 32, 33 is connected to the movable cam member 34, and the other end thereof is connected to both ends of the holder 31 or its vicinity.

In the present embodiment, the shape memory spring 32 has a characteristic that the tensile elastic force increases almost linearly with increasing temperature.

Although the holder 31 is slidable in the longitudinal direction with respect to the main body 10, it is maintained in the stop position in the automatic control mode described later, and the movable cam member 34 has both springs according to the outdoor temperature environment. The elastic force of (32, 33) is controlled to be in a balanced position.

There is a slight nonuniformity in the temperature characteristic of the shape memory spring 32, and this nonuniformity can be compensated by adjusting the connection position of the bias spring 33 to the holder 31, for example. As a result, the actuator 30 can obtain a predetermined temperature characteristic.

On the upper surface of the movable cam member 34, a cam groove 34a inclined with respect to the circumferential wall 12c of the main body 10 is formed, and the cam plate 34a of the operation plate 20 described above is formed. A projection 23 is entered.

The ventilation device 8A on the outdoor side has a temperature characteristic shown by the solid line in FIG. 7. Specifically, when the outdoor air temperature is the upper limit temperature (for example, 15 ° C.), since the elastic force of the shape memory spring 32 is strong, the movable cam member 34 is located near the left side, thereby being shown in FIG. 6A. As shown, the projection 23 of the operation plate 20 is located at the closed end of the cam groove 34a. As a result, as shown by solid lines in FIGS. 5A and 5B, the inclination angle θ (opening angle) with respect to the circumferential wall 12c of the operating plate 20 becomes the maximum value θmax, and furthermore, the opening area of the ventilation passage 16 is increased. It is the maximum. In addition, as shown in Fig. 6A, an auxiliary groove 34b parallel to the circumferential wall 12c is connected to the closed end of the cam groove 34a, and the air temperature rises so that the movable cam member 34 Even if it moves to the left direction, the inclination angle of the operation plate 20 does not increase.

As the outdoor temperature decreases, when the elastic force of the shape memory spring 32 is weakened, the movable cam member 34 is pulled by the bias spring 33 and moved in the right direction as shown in Fig. 6B. As a result, the projection 23 of the operating plate 20 approaches the main wall 12c by the cam action with the cam groove 34a. As a result, as shown by phantom lines in FIGS. 5A and 5B, the inclination angle θ with respect to the circumferential wall 12c of the operating plate 20 decreases, and the opening area of the ventilation passage 16 decreases.

6B, the projections 25 of the operating plate 20 abut against the fixed cam member 45, which will be described later, so that the rotational movement Is regulated. Therefore, even if the air temperature is lower than the lower limit temperature, the inclination angle θ of the operating plate 20 is maintained at the minimum value θ min. That is, the ventilation passage 16 does not become a fully closed state (the state in which the opening area of the ventilation passage 16 is zero). For example, the minimum value [theta] min is about 1/3 of the maximum value [theta] max. As a result, a minimum amount of air is secured in the automatic control mode. As is apparent from the above description, the fixed cam member 45 is also provided as a stopper (rotational motion restricting means) for the operating plate 20.

In the present embodiment, as best shown in Figs. 6A to 6C, the closing plate 40 is provided with a forced closing means 40 which forces the operating plate 20 to be completely closed by manual operation. This forced closing means 40 has an operation knob 41 and the fixed cam member 45.

4A and 5B, holes 11z and 14z are formed in the vicinity of the right end of the indoor shape member 11 and the heat insulating mold member 14, and these holes 11z and 14z are formed in each of the holes 11z and 14z. The frame member 42 is fitted. The operation knob 41 is slidably supported by the frame member 42. When the operation knob 41 is located on the right side as shown in Figs. 6A and 6B, it is in the automatic control mode, and in the forced closing mode when it is located on the left side as shown in Fig. 6C.

The operating handle 41 is inserted into the engaging hole 22 of the operating plate 20, whereby the operating plate 20 moves in the longitudinal direction when the operating handle 41 is in the automatic control mode. This is prohibited and only rotational movement is possible, and as described above, the inclination angle is automatically controlled in response to the outdoor temperature by the actuator 30.

5A, 5B, and 6A to 6C, the locking member 39 is fixed to the holder 31 of the actuator 30. The locking member 39 has a pair of hooking hooks 39a extending upward, and the locking handles 39a are fitted with the operating handles 41. Thereby, when the operation knob 41 is in the automatic control mode position, the holder 31 is held at a predetermined stop position.

The fixed cam member 45 is spaced apart from the moving cam member 34 in the longitudinal direction of the main body 10 and is fixed to the shape member 12 of the main body 10. The fixed cam member 45 has the cam surface 45a of the inclination equivalent to the cam groove 34a of the movable cam member 34. As shown in FIG.

When the operation knob 41 is moved in the left direction to the forced closing mode, the operation plate 20 moves in the same direction, and as shown in FIG. 6C, the protrusions 24 of the operation plate 20 are fixed cams. It comes in contact with the cam surface 45a of the member 45, is guided by this cam surface 45a, and is close to the circumferential wall 12c. In turn, the operation plate 20 is close to the main wall 12c, and the packing 28 fixed to the lower edge of the operation plate 20 contacts the main wall 12c, so that the vent 12x of the main wall 12c is substantially It is closed (ie the opening area of the ventilation passage 16 becomes substantially zero).

In addition, since the holder 31 of the actuator 30 is coupled to the operation knob 41 through the locking member 39, the actuator 30 also follows the operation knob 41 to follow the operation plate 20. Together, the main body 10 is moved in the longitudinal direction. Therefore, when moving the operation knob 41 to the forced closing mode position, the deformation amount of the shape memory spring 32 can be suppressed, and the life of it can be extended.

The indoor ventilator 8B has the temperature characteristic which shifted the temperature characteristic of the indoor ventilator 8A to the high temperature side, as shown with the dotted line of FIG. That is, in order to obtain the same inclination angle of the operation plate 20, the temperature required by the temperature sensitive actuator 30 of the indoor ventilator 8B is the temperature sensitive actuator 30 of the outdoor ventilator 8A. ) Is higher than the required temperature. For example, the temperature when the inclination angle θ of the operating plate 30 decreases to reach the minimum value θ min is 10 ° C., and the temperature when the inclination angle θ increases to reach the maximum value θ max is 20 ° C.

The difference in the temperature characteristics of the ventilation devices 8A and 8B is obtained by subjecting each shape memory spring 32 to heat treatment (shape memory processing) to make the temperature characteristics different from each other.

In the above configuration, in the state where the chassis doors 5A and 5B of the double glazing 2 are closed, a high heat insulating effect is obtained by the heat insulating space 6. As described above, in the automatic control mode, the outdoor and indoor ventilation devices 8A and 8B allow the air to flow, and the indoor space 1c is always ventilated.

When the outdoor air temperature is 5 ° C. during cold weather, the opening area of the ventilation passage 16 of the outdoor ventilation device 8A is minimized.

The temperature sensitive actuator 30 of the indoor ventilator 8B operates in response to the outdoor air temperature, that is, the air temperature of the heat insulation space 6, and the air temperature of the heat insulation space 6 is higher than the outdoor air temperature. . Therefore, if the temperature sensitive actuator 30 of the indoor ventilator 8B has the same temperature characteristic as the outdoor ventilator 8A, the ventilation passage 16 of the outdoor side ventilator 8A will be described. The opening area becomes large. However, as mentioned above, since the temperature characteristic of the indoor ventilation apparatus 8B is shifted to the high temperature side as shown by the dotted line in FIG. 7, increase of the opening angle (theta) of the operating plate 20 can be suppressed. . For example, when the temperature of the heat insulation space 6 was about 5 degreeC high compared with the outdoor temperature, and was 10 degreeC, opening can be suppressed only by the angle shown by (DELTA) (theta) in FIG. 7, and the opening of the ventilation path 16 is opened. The area can be minimized as in the ventilation apparatus 8A on the outdoor side.

It is.

In the second embodiment, cold air introduced from the outdoor ventilation device 8A to the lower end of the thermal insulation space 6 during the cold weather is warmed up in the thermal insulation space 6 to rise to reach the indoor ventilation device 8B. And enter the indoor space 1c. Therefore, heat loss can be further suppressed.

In addition, 2nd Embodiment is a technique applicable beyond the scope of this invention, For example, it is not limited to a temperature sensitive type, A passive ventilation apparatus can also be used.

In this structure, a part of the air which became hot in the process of raising the heat insulation space 6 in the summer from the lower side ventilation apparatus 8A 'of the lower side can be discharged | emitted from the upper side auxiliary ventilation apparatus 8C. In this case, it is preferable to shift the temperature characteristic of the auxiliary ventilation apparatus 8C from the ventilation apparatus 8A 'to the high temperature side. More specifically, it is preferable to shift to the high temperature side about the same as the ventilation apparatus 8B of an indoor side, or more than this.

The present invention is not limited to the above embodiment and various aspects are possible. For example, although a tension coil spring was used as a shape memory spring and a bias spring, you may use a compression coil spring.

In the above embodiment, an elastic body made of a shape memory alloy is used as the temperature sensitive actuator, but a bimetal or the like may be used.

The forced closing means may be omitted. In this case, only the rotary motion by the automatic control is performed by the operation plate, and one end of each of the shape memory spring and the bias spring is fixed to the main body.

The operating plate may be adjusted to adjust the opening area of the ventilation passageway by sliding in the longitudinal direction of the apparatus body in contact with the peripheral wall of the apparatus main body without rotating. In this case, the movable body is connected to the fixed position of the operating plate.

In the automatic adjustment mode, the minimum value of the opening area of the ventilation passage may be zero.
