It is necessary to pull out the filters 111 and 112 along the plates 113, 114, and 115, and for this reason, the filters 111 and 112 require a strong frame around the outer periphery, which causes high manufacturing costs. When washing the filters 111 and 112 with water, it is difficult to wash the filters because there is a frame around the outer periphery of the filters.
There was a risk of deforming the 2.

The present invention solves the above-mentioned conventional problems by integrally forming a heat exchange element provided at the intersection of the exhaust passage and the air supply passage with a foamed resin frame, and also by forming the heat exchange element at the intersection of the exhaust passage and the air supply passage. An integrated filter is provided across the airflow entry surface,
By hooking this filter onto the foam resin frame and fixing it on the frame, only one filter is required, and a strong frame is not required, which reduces manufacturing costs and eliminates the need for a frame. Therefore, it is an object of the present invention to provide a heat exchanger wedge-shaped ventilation device whose filter can be easily cleaned, especially washed with water.

Means for Solving the Problem In order to solve this problem, the present invention partitions an exhaust passage from the indoor suction port to the outdoor discharge port and an air supply passage from the outdoor suction port to the indoor discharge port. An exhaust blower that blows air to the exhaust passage and a supply air blower that blows air to the air supply passage are provided inside the main body, and a heat exchange element is provided at the intersection of the exhaust passage and the air supply road. The heat exchange element is formed integrally with a frame made of foamed resin, and an integrated filter is provided straddling the entrance surfaces of the exhaust air flow and supply air flow of the heat exchange element, and the filter hook is provided on the frame made of foamed resin. It is integrally molded.

Function: With this configuration, indoor air is sucked in from the indoor suction port, passes through the heat exchange element, and is exhausted outdoors from the outdoor discharge port.
Outdoor air is sucked in from the outdoor suction port, passes through the heat exchange element, and is supplied indoors from the indoor discharge port.The heat exchange element performs heat exchange ventilation, and the exhaust flow from the heat exchange element and A hook is formed by integrally molding an integral filter provided across the entrance surface of the air supply flow into a foamed resin frame, and is fixed by being hooked to the part.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 4. In the figure, reference numeral 1 denotes a main body that divides an exhaust passage 4 from the indoor suction port 2 to the outdoor discharge port 3 and an air supply passage 7 from the outdoor suction port 5 to the indoor discharge port 6. , an exhaust air blower that blows air into the exhaust passage 4 and an air supply air blower 9 that blows air into the air supply passage 7. A heat exchange element 10 is provided at the intersection of the exhaust passage 4 and the air supply road 7, and is formed integrally with the heat exchange element frame 1 made of foamed resin.
