Abstract

(57) [Abstract] [Purpose] In a ventilation device that performs natural ventilation between two adjacent compartments partitioned by a door, the door itself has a neat structure and is inexpensive and conspicuous. To obtain a ventilation system using a door frame that can perform ventilation without using it. In a ventilation device for performing natural ventilation between two adjacent partitioned spaces 2 and 3 partitioned by a door, at least a required portion 8 of a door frame 4 is hollow, and the hollow portion 8 Ventilation holes 13 and 14 communicating with two compartment spaces 2 and 3 respectively adjacent to the two different surfaces 11 and 12 are provided, and the two compartment spaces 2 adjacent to each other through the ventilation holes 13 and 14 and the hollow portion 8. A ventilation system that uses a door frame that naturally ventilates between the three.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ventilator using a door frame for natural ventilation between two adjacent compartment spaces partitioned by a door.

[0002]

[Prior art]

 Conventionally, when natural ventilation is performed by using a door between two adjacent partitioned spaces partitioned by a door, that is, two rooms partitioned by a door, generally a door is provided with a gutter or an undercut. Natural ventilation is provided through the louver or undercut.

[0003]

[Problems to be solved by the device]

 According to the conventional ventilator using the door described above, the door must be provided with a louver and an undercut, which is very noticeable in design and may not match the surrounding design. However, there were some problems such as restrictions on the design of the door itself, and in the case of the gallery method, the structure of the door itself was complicated and expensive.

The present invention has been made in order to solve the above-mentioned problems. The door itself has a refreshing structure and uses a door frame which is inexpensive and can ventilate inconspicuously. The purpose is to obtain a ventilation system.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, a ventilator using a door frame according to the present invention is a ventilator that performs natural ventilation between two adjacent partitioned spaces partitioned by a door. The required part is made hollow, and ventilation holes communicating with two adjacent partition spaces are provided on two different surfaces of the hollow part, and between the ventilation hole and the two adjacent partition spaces through the hollow part. The feature is that natural ventilation is performed at.

In addition, the door frame is a vertical frame.

Further, the vent hole is formed of a large number of punching small holes.

[0008]

[Action]

 Since the ventilator using the door frame according to the present invention is configured as described above, a space between the two adjacent partition spaces partitioned by the door is a hollow space provided in the door frame. Natural ventilation is performed by convection, air flow, etc. between the one compartment space and the other compartment space through the site and the ventilation hole.

Further, the natural ventilation as described above is performed through the hollow portion and the ventilation hole formed in the vertical frame of the door frame.

Further, an appropriate ventilation amount can be obtained by appropriately selecting the number or size of a large number of punching small holes forming the ventilation hole.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 is a front view of a door and a door frame, FIG. 2 is a sectional view taken along line AA in FIG. 1, FIG. 3 is a view taken in the direction of arrow B in FIG. 2, and FIG. 4 is a view taken in the direction of arrow C in FIG.

The door 1 is attached to a door frame 4 so as to be openable and closable, and divides the door 1 into two adjacent partition spaces, that is, rooms 2 and 3. The door frame 4 is composed of an upper frame 5, a lower frame 6 and a vertical frame 7, and a predetermined position 8 in the vertical direction of the vertical frame 7 is provided with upper and lower lids 9 and 10, and a space between them is formed in a hollow shape. There is.

As shown in FIGS. 2 to 4, the surface 11 facing the partitioned space 2 and the surface 12 facing the partitioned space 3 of the hollow portion 8 of the vertical frame 7 are adjacent to each other as shown in FIGS. Ventilation holes 13 and 14 which are made up of a large number of punching small holes communicating with No. 3 are provided.

Therefore, according to the above configuration, between the two adjacent partition spaces 2 and 3 partitioned by the door 1, the hollow portions 8 and the ventilation holes 13 and 14 provided in the vertical frame 7 are provided. Natural ventilation is performed between one of the two adjacent partitioned spaces 2 and 3 and the other of the partitioned spaces through convection, air flow, and the like.

Therefore, natural ventilation can be performed by using the door frame 4 without providing a rattle or an undercut on the door itself. The ventilation amount can be properly set by appropriately selecting the number or size of a large number of punching small holes forming the ventilation holes 13 and 14.

[0016]

[Effect of device]

 As described above, according to the ventilator using the door frame of the present invention, since the door frame can be used for natural ventilation, the door itself has a neat and simple structure and a design. In addition to being able to eliminate the above restrictions, it is possible to obtain a ventilator that allows the door itself to be manufactured at a low cost, and that can ventilate without being noticeable in terms of design.
