Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window mounting heat exchange type ventilation fan mounted on a window frame or the like to ventilate a room.

[0002]

2. Description of the Related Art At present, a ventilation fan for exhausting indoor air (inside air) to the outside and taking in outdoor air (outside air) into the room is widely used.

[0003] Among the ventilation fans, there is a heat exchange type ventilation fan for exchanging heat between inside air and outside air, instead of merely exchanging outside air for inside air.

FIG. 4 is a diagram showing the configuration of a conventional example (Japanese Patent Laid-Open No. 6-323593) of a heat exchange type ventilation fan incorporating a heat exchange element. In the illustrated configuration, both the exhaust fan 3 and the intake fan 4 are provided adjacent to the outside of the room, and the intake A
A heat exchange element 5 is provided at the intersection of the flow path of s and the flow path of exhaust Ae. Here, heat exchange between the intake As and the exhaust Ae reduces the temperature difference between the two.

Heat exchange element 5 used for heat exchange type ventilation fan
, There are many orthogonal heat exchange elements. An orthogonal heat exchange element is an element made of a metal having a small specific heat such as aluminum, and provided with a flow path of air that passes through the inside so as to be orthogonal to each other without mixing outside air and inside air. Can be changed by about 1 ° C.

[0006] Since the orthogonal heat exchange element has a relatively simple configuration, it is advantageous in reducing the manufacturing cost of the heat exchange type ventilation fan and simplifying the configuration.

According to such a heat exchange type ventilation fan, for example, when the temperature of the outside air is low and the temperature of the inside air is high by heating, the low-temperature outside air is heat-exchanged with the high-temperature inside air before being taken in. Can be reduced. Conversely, when the temperature of the outside air is high and the temperature of the inside air is low due to cooling, the high temperature outside air is heat-exchanged with the low temperature inside air and then taken in, thereby alleviating the rise in indoor temperature due to ventilation.

[0008]

However, the above-described heat exchange type ventilation fan is constructed such that a hole is formed in a wall of a house according to the size and shape of the heat exchange type ventilation fan, and the hole is attached thereto.

[0009] Therefore, it is necessary to construct the holes for installation. Also, if you remove it after installing it, the hole after removing the heat exchange type ventilation fan will remain, so if you relocate it, close this hole,
It is necessary to make a new hole.

It is generally considered that the size and shape of the ventilation fan are desirably small and thin in order to reduce the area occupied in the room. However, in the above-described configuration of the conventional example, it is necessary to provide the heat exchange element 5 at a tilt as shown in the figure in order to provide the flow path for the intake As and the flow path for the exhaust Ae. Therefore, in the configuration of the conventional example, the heat exchange type ventilation fan needs to have a thickness equal to or greater than the length of the side L2 of the heat exchange element 5, preventing the heat exchange type ventilation fan from being thinned.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and provides a heat exchange type ventilation fan for window mounting, which can be mounted without making a hole in a wall and has a configuration advantageous for thinning. It is intended to do so.

Consumption can be reduced. Further, when the user goes out, the safety of the window mounting heat exchange type ventilation fan can be further enhanced by operating the window mounting heat exchange type ventilation fan only by the electric power obtained by solar energy.
