Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating sash for providing ventilation. 2. Description of the Related Art A main purpose of a heat insulating sash is to block heat transfer between the outside and the inside of a room, to prevent the occurrence of dew condensation, and to improve the efficiency of heating and cooling. However, since the insulating sash has high airtightness at the same time, there is a case where a ventilation device is provided for indoor ventilation. For example, Japanese Patent Application Laid-Open No. H10-1151
No. 56 discloses connecting an inner body and an outer body made of an aluminum mold member with a resin bridge, connecting a ventilation port of the outer body and a ventilation port of the inner body through an inner space of the frame material, and operating the ventilation port of the outer body. A heat insulating sash provided with an operating plate moved by a knob is disclosed. However, since the outside air fills the inner space of the frame material in this heat insulating sash, the inside air is cooled by the outside air, thereby impairing the heat insulating effect. In addition, dew condensation easily occurs due to cooling, and a special configuration is provided for discharging the dew condensation inside the frame material. Such a situation occurs when the indoor side material of the heat insulating sash is made of metal such as aluminum alloy and has high thermal conductivity. [0003] The present invention incorporates a heat insulating sash inside a frame material to allow natural ventilation, and also forms dew condensation on the indoor side of the heat insulating sash and inside the frame material constituting the heat insulating sash. It is an object of the present invention to provide a heat insulating sash with a ventilating device that prevents the occurrence of airtightness and a heat insulating sash that can sufficiently exhibit the performance of the ventilating device. [0004] An insulating sash having an insulating frame and a ventilating device is provided. The ventilator is housed in an insulating frame and has an outdoor opening and an indoor opening.The air passage connecting the outdoor opening and the indoor opening is provided by the insulating frame containing the ventilating device. It shall be isolated from the internal space thermally and as an air passage. That is, at least the outer surface of the ventilation device is formed of a heat insulating material, and is separated from the internal space of the heat insulating frame by an outer wall forming an air flow passage so that air to be circulated for ventilation does not leak into the internal space of the heat insulating frame. . When the low-temperature outside air taken in at the time of ventilation flows into the internal space of the heat insulating frame, the indoor side portion of the heat insulating frame is cooled, so that the heat insulating effect is not hindered, and dew is not formed on the internal space of the frame material. Further, the vicinity of the outer profile exposed to the outside air in the inner space of the heat insulating frame is cooled, and it is possible to prevent the low temperature from reaching the inner profile through the outer surface of the ventilator. Further, in order to provide sufficient ventilation, a ventilator which is inevitably large in size may have a configuration in which the internal space of a heat insulating frame for accommodating the ventilator is expanded at least at a location for accommodating the main body. Means of expansion include joining additional profiles with heat insulating material or increasing the indoor and outdoor dimensions of profiles located on the indoor side. The design of the ventilator is performed without difficulty, and a sufficient heat insulating effect can be obtained together with the required ventilation function. Insulation frames usually have a structure in which an outer profile and an inner profile are connected to each other with a thermal insulator, but have an outer profile, an intermediate profile, and an inner profile, and the outer profile and the intermediate profile are combined. In some cases, the outer and outer intermediate members are connected by an outer insulating material, and the intermediate and inner members are connected by an inner insulating material. Each of these sections is often formed from an extruded aluminum alloy. The cross-sectional form varies depending on the use of the sash and which part of the sash constitutes it. Further, a hollow structure may be used for a portion that needs to have high flexural strength. When the heat insulating frame is composed of, for example, an upper frame material, a lower frame material, and left and right vertical frame materials, all of these frame materials may not have the same heat insulating structure. The heat insulating material is often made of synthetic resin such as hard vinyl chloride, and is attached by caulking a cast or molded product. The ventilation device may be constituted by a main body, a sleeve, and a ventilation control section provided on the main body. The ventilator generally has a shape that is long in the longitudinal direction of the frame material that forms the heat insulating sash. The sleeve forms an air flow passage penetrating in the indoor and outdoor directions, and at least the outer surface is formed of a heat insulating material. When the sleeve is configured to be long in the longitudinal direction of the frame material, the air flow path extends in the longitudinal direction of the frame material forming the heat insulating sash, and the air flow path has a wide band shape. In many cases, the sleeve is formed of a weather-resistant synthetic resin in half and molded together to form an air flow passage, one end of which is an outdoor vent, and the interior of which is a connection port to the main body. [0007] The main body also has at least an outer surface formed of a heat insulating material, has an indoor ventilation port on the upper surface or the indoor side surface, and has a connection port on the outdoor surface or the bottom surface.
It is often formed as a long box as a whole. The ventilation control section adjusts the flow amount of the air flow passage, and adjusts the opening amount of the outer opening provided in the outer profile and the opening amount of the inner opening by a slide plate provided with a slit, or a heat insulating frame. A structure in which a cylindrical rotor that is long in the longitudinal direction of the frame material to be configured is arranged inside the main body, and air can flow through a long ventilation slit provided in the rotatable rotor and penetrating in the diametric direction. [0008] The main body containing the rotor is disposed on the inner peripheral side of the inner profile, its indoor vent is connected to the inner opening provided in the inner profile, and the sleeve is formed on the inner periphery of the outer profile and the intermediate profile. The air outlet on the side is connected to the outer opening provided in the outer profile, and the connection port of the sleeve is connected to the connection port of the main body. Then, an air flow passage communicating from the outer opening of the outer profile to the inner opening of the inner profile is formed. Although this air flow passage is housed inside the heat insulating frame, it does not communicate with the internal space of the heat insulating frame, and outside air passes through a passage isolated from the internal space of the heat insulating frame into the room. Therefore, the heat insulating frame is not cooled. Also, since the outer profile of the heat insulating frame is exposed to the outside air, the temperature near the outer profile of the inner space in the heat insulating frame becomes low, and this low temperature travels along the outer surface of the sleeve and the main body and the inside profile of the heat insulating frame. However, this low temperature propagation is prevented by forming at least the outer surface of the ventilator with thermal insulation. In addition, the internal space of the heat insulating frame where the main body is to be housed is expanded by the intermediate shape and the internal heat insulating material (or the internal heat insulating material and the internal shape material), and it is necessary to force the ventilation device into the internal space of the heat insulating frame. And the ventilation system can be designed with a margin. Up to now, the heat insulating frame in which the shoji is fitted has been described, but it is also conceivable to install a ventilation device with a similar configuration in the heat insulating frame forming the frame of the shoji. In that case, the insulating frame corresponds to the above-described insulating frame.

The rotor 32 is provided with a diametrical through hole 41 over the entire length, and the direction of the through hole can be changed by the operation lever 33. Further, since the rotor 32 has its outer peripheral surface in contact with the body portion 34 and only the upper and lower parts are desired for the indoor ventilation port 38 and the connection port 42, the rotor 32 extends from the connection port 42 to the indoor ventilation port 38.

Is accommodated in a space 26 that is expanded from the normal space formed by these and the lower cover member 9b. And the ventilation device 1
0 falls in the internal space of the heat insulating frame 5. With the above construction, the heat-insulating sash 1 is constructed such that the inner profile 14 of each frame 11 is thermally isolated by the outer profile 12, the outer thermal insulator 15 and the inner thermal insulator 16, so that There is no transfer of heat in the directions, dew condensation based on the temperature difference can be prevented, and the efficiency of cooling and heating can be improved. Further, the air on the outdoor side and the air on the indoor side are transferred from the outer opening 18 connected to the hollow portion 17 defined as an equal pressure space to the sleeve 29.
And it can flow to the inside opening 27 through the main body 28, which is effective for indoor ventilation. Moreover, at that time, the circulating air moves from the main body 28 through a passage isolated from the space inside the frame material by the wall of the sleeve 29,
Since it does not spread into the internal space of the frame member 11, the outer surface of the ventilation device 10 is a heat insulating material, and the outer shape member 12
Since the low temperature in the vicinity does not reach the inner profile 14 through the ventilation device 10, the inner profile 14 and the decorative cover 9 are not cooled. Further, the ventilation device 10 is long in the longitudinal direction of the frame member 11 and the outside air vent 44 and the inside air vent 38 of the sleeve 29 can be formed in a slit-like wide area, so that the ventilation efficiency is improved. The ventilation can be easily adjusted by the operation lever 33 if necessary. Further, the lower frame member 11b which is connected to the main body 28 of the ventilator 10 by the inner heat insulating material 16 and is expanded more than usual by the intermediate shape material 13 or the inner shape material 14, which is the third shape material.
Since the main body 28 has a sufficient size and a sufficient ventilation volume, the main body 28 can be provided in the space 26. [0021] Since the air for the ventilation according to the present invention is circulated is isolated from the internal space of the heat insulating frame, an indoor side profile of the outside air and indoor air is filled in the internal space of the heat insulating frame Cooling and condensation in the interior space of the insulation frame are prevented,
Since the low temperature near the outer profile of the internal space in the heat insulating frame does not reach the inner profile through the ventilation device, the function of the heat insulating sash is hardly impaired. Conversion air flow passage for the gas is isolated by the sleeve and the body of the ventilator, since no fills the interior space of the heat insulating frame, that the heat insulating performance of the insulating sash by the air flow during ventilation is reduced Nothing. Further, by providing the sleeve, it is usually easy to form an air flow passage for ventilation in a place where the interval is narrow due to a structure for supporting a shoji or glass. In addition to the outer and middle frames, the inner frame is connected to the inner frame by using the inner frame, so the space inside the frame can be increased and sufficient ventilation can be provided for this space. The provided ventilation device can be arranged with a design margin.
