Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation fan, and more particularly, to a ventilation fan mounted on a window frame.

[0002]

2. Description of the Related Art In a conventional air ventilator of this kind, for example, disclosed in Japanese Patent Application Laid-Open No. 53-82042, when air is introduced into a room to ventilate the room, the air inside the room is exhausted. Heat is exchanged between the air and the introduced outside air so that the temperature in the room is not extremely changed by the introduced outside air.

[0003]

However, in the above-mentioned conventional ventilating fan, since the exhaust port on the indoor side is located on the upper frame side of the window frame, the weight per unit volume is limited to smoke. However, there is a problem that carbon dioxide, dust, and the like, which are larger than the above, float on the floor side and are difficult to be discharged outside through an exhaust port.

[0004] Therefore, an object of the present invention is to provide a ventilation fan without such a problem.

[0005]

According to a first aspect of the present invention, there is provided a box unit having an indoor panel and an outdoor panel incorporated in a window frame. A first passage defined between an indoor upper air vent formed above the indoor panel and an outdoor lower air vent formed below the outdoor panel; A second passage defined between an indoor lower air vent formed on the lower side and an outdoor upper air vent formed on the upper side of the outdoor panel, to be located on the indoor upper air vent side; A first fan mounted in the first passage,
A second fan mounted in the second passage so as to be positioned on the indoor side lower vent side, a countercurrent heat exchange means for performing heat exchange between the first passage and the second passage, and First
That is, an air-conditioning ventilator including control means for changing the rotation directions of the fan and the second fan is configured.

[0006]

According to the technical means of the first aspect of the present invention, the rotation directions of the first fan and the second fan are appropriately changed, so that the indoor upper vent is changed from the suction port to the discharge port, and the indoor lower vent is changed. The vent can be switched from the outlet to the inlet.

[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 and 2, a ventilation device 30 is provided on the left side of a frame 20 fitted in an opening 11 of a building 10.
Are assembled so as to extend vertically. Thus, the box portion 31 is the left frame 2 of the frame 20.
1. A side plate 25 that is parallel to the left frame 21 of the frame 20 and connects the upper frame 22 and the lower frame 23 of the frame 20 to each other, and the indoor side of the left frame 21 and the indoor side of the side plate 25 The inner panel 32 and the outer panel 33 that connect the outdoor side of the left frame 21 and the outdoor side of the side plate 25 are connected. The opening between the side plate 25 and the right frame 26 of the frame body 20 is formed by a pair of It can be opened and closed by glass doors 27.

Inside the box portion 31, there are first mutually independent first
A passage 35 and a second passage 36 are formed, and a counter-current heat exchanger 39 for exchanging heat between fluids passing through the passages 35 and 36 is provided between the passages 35 and 36. Have been.

On the upper and lower sides of the inner panel 32, a room-side upper ventilation port 41 and a room-side lower ventilation port 42 are provided, respectively.
Are formed, and the indoor-side upper ventilation port 41 and the indoor-side lower ventilation port 42 constitute the indoor-side ventilation ports of the first passage 35 and the second passage 36, respectively.

On the upper and lower sides of the outer panel 33, an outdoor upper air vent 51 and an outdoor lower air vent 52, respectively.
Are formed, and the outdoor-side upper ventilation port 51 and the outdoor-side lower ventilation port 52 constitute outdoor-side ventilation ports of the first passage 35 and the second passage 36, respectively.

In the first passage 35, a first fan 61 is provided.
It is installed near the indoor-side upper ventilation port 51. Also,
In the second passage 36, a second fan 62 is installed near the indoor-side lower ventilation port 52.

A control panel 70 is fitted into the inner panel 32 so as to be located below the indoor upper ventilation port 41. Then, when the switch 71 of the control panel 70 is turned on,
In response to an instruction from a control device (not shown), the first fan 6
1 (the second fan 62) rotates in the forward direction and is outside (indoor)
The air of the outdoor side lower vent 52 (the indoor lower vent 4
2), and is introduced into the room (exhausted to the outside) from the indoor upper vent 41 (outdoor upper vent 51). The air passing through the first passage 35, that is, the air from the indoor side, and the air passing through the second passage 36, that is, the air from the outdoor side, exchange heat in the countercurrent heat exchanger 39. Extremely high heat exchange rate (up to 100
%), The temperature inside the room is hardly affected by the temperature of the air introduced from outside. This flow of air is indicated by arrows in FIG. Therefore, carbon dioxide gas (which is inevitably generated when using an oil stove) and dust / dust which are heavy and float on the floor side can be sucked in from the indoor side lower ventilation port 42 and discharged to the outside.

Conversely, the switch 72 of the control panel 70
By turning on both the first fan 61 and the second fan 62, the indoor-side upper ventilation port 41 and the indoor-side lower ventilation port 42 can be used as a suction port and a discharge port, respectively. . That is, air flows in the direction opposite to the arrow in FIG. Therefore, when the room is filled with smoke due to smoking, the raised smoke can be discharged outside from the room side upper vent 41.

Note that the above description is merely an example of the embodiment of the present invention, and as long as the technical idea of the present invention is used, configurations different from the above embodiment are also included in the technical scope of the present invention. is there.

[0016]

According to the first aspect of the present invention, the following effects can be obtained.

[0017] By changing the rotation direction of both fans, the suction port on the indoor side can be changed, and the air can be efficiently discharged according to the contaminants.
