Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat exchange type ventilator for ventilating a house or an office.

2. Description of the Related Art Conventionally, this type of heat exchange type ventilator has a configuration as shown in FIGS. In the figure, reference numeral 100 denotes an exhaust passage 103 from the indoor suction port 101 to the outdoor discharge port 102, and an air supply passage 106 from the outdoor suction port 104 to the indoor discharge port 105.
The exhaust passage 103 is provided in the exhaust passage 103, the supply passage 106 is provided with the supply blade 108, and the motor 109 for opening them is provided.The exhaust passage 103 and the supply passage
A heat exchange element 110 was provided at the intersection with 10. Filters 111 and 112 are provided on the entry surfaces of the heat exchange element 110 for the exhaust flow and the supply air. 113, 114, 115 and 116 are partition plates for holding the heat exchange element 110 and for exhaust passage 103 and air supply passage.
106, and the filters 111 and 112 are held and positioned. Reference numeral 117 denotes an inspection lid, which is detachably attached to the inspection opening 118 of the heat exchange element 110 provided on the side surface of the main body 100. In such a configuration, when the motor 109 is operated, the room air flows in the indoor side suction port 10 as shown by the arrow X → X ′.
1, the air is exhausted to the outside from the outdoor outlet 102 through the heat exchange element 110 through the exhaust passage 103, and the outdoor air is sucked from the outdoor outlet 104 as shown by arrows Y. The air was supplied into the room from the indoor outlet 105 through the heat exchange element 110 through the air passage 106, and the heat exchange air was supplied by the heat exchange element 110.

Problems to be Solved by the Invention In such a conventional configuration, when cleaning the filters 111 and 112, the inspection cover 117 detachably attached to the opening 118 provided on the side surface of the main body 100 is removed, and the partition plate is removed. It is necessary to draw out the filters 111 and 112 along the lines 113, 114 and 115, and therefore, the filters 111 and 112 need to have a strong frame on the outer periphery, which is a factor of increasing the manufacturing cost. In addition, when the filters 111 and 112 are washed with water, it is difficult to perform the operation because there is a frame on the outer periphery of the filters.
There was a risk of deforming the 112.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, in which a heat exchange element provided at an intersection of an exhaust passage and an air supply passage is formed integrally with a foamed resin frame, and an exhaust flow and a supply An integrated filter is provided across both air entry surfaces, and this filter is hooked and fixed to the hook section integrally molded with the foam resin frame, so that only one filter is required and a strong frame is not required. Accordingly, it is an object of the present invention to provide a heat exchange type ventilator which can reduce the manufacturing cost, and can easily clean a filter, particularly, wash with water because a frame is unnecessary.

Means for Solving the Problems In order to solve this problem, the present invention divides an exhaust passage from an indoor suction port to an outdoor discharge port and an air supply passage from an outdoor suction port to an indoor discharge port. Inside the body
An exhaust blower that blows air to the exhaust passage and an air blower that blows air to the air supply passage are provided, and a heat exchange element is provided at an intersection of the exhaust passage and the air supply passage. A filter without a frame is formed integrally with a frame of a foamed resin in which a hook portion is integrally formed, and is provided across both the inflow surfaces of the exhaust flow and the supply air of the heat exchange element.

Operation With this configuration, the indoor air is sucked in from the indoor side suction port, is exhausted to the outside through the outdoor-side discharge port through the heat exchange element, and the outdoor air is sucked in from the outdoor side intake port and is discharged through the heat-exchange element to the indoor side discharge port. Air is supplied into the room from the outlet, and heat exchange ventilation is performed by the heat exchange element.In addition, an integral filter provided across both the inflow surfaces of the exhaust flow and the supply air flow of the heat exchange element is formed of a foam resin frame. It is hooked and fixed to the hook part integrally formed with the helmet.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. In the figure, reference numeral 1 denotes a main body that defines an exhaust passage 4 extending from the indoor suction port 2 to the outdoor discharge port 3 and a supply passage 7 extending from the outdoor suction port 5 to the indoor discharge port 6. , An exhaust blower that blows air to the exhaust passage 4 and an air supply passage 7
Has an air supply blower 9 for blowing air to the air. Reference numeral 10 denotes a heat exchange element provided at the intersection of the exhaust passage 4 and the air supply passage 7, and is formed integrally with the heat exchange element frame 1 made of foamed resin. Reference numeral 12 denotes an integral filter provided over the exhaust flow entry surface 13 and the supply air entry surface 14 of the heat exchange element 10. The integral filter has elasticity and is pulled by a filter hook 15 integrally formed on the heat exchange element frame 11. Multiply,
It is detachably fixed. Reference numeral 16 denotes an opening provided in the main body 1 for attaching and detaching the filter 12 and the like, and is configured to be opened and closed by the inspection lid 17.

In the above configuration, the exhaust blower 8 and the air supply blower 9
Is operated, the room air is sucked from the indoor side suction port 2 as shown by the arrow A → A ′, passes through the exhaust passage 4 and the heat exchange element 10.
Through the outdoor discharge port 3 to the outside, and the outdoor air is sucked from the outdoor side suction port 5 as shown by arrows B.
Through the intake passage 7, through the heat exchange element 10, and through the indoor outlet 6
The air is further supplied into the room, and the heat exchange element 10 enables heat exchange ventilation. Further, since the filter 12 is provided so as to extend over the exhaust flow entry surface 13 and the supply air entry surface 14 of the heat exchange element 10, only one filter is required, and the filter hooking portion integrally formed with the heat exchange element frame 11 is provided. Since it is detachably fixed by hooking it on 15, it is not necessary to have a strong frame, so it is very inexpensive as compared with the related art. When the filter 12 is taken out of the main body 1 and cleaned, as shown in FIG. 4, the inspection lid 17 provided with the opening 16 is removed, and the filter 12 is bent slightly inward to attach the filter 12 to the filter hooking portion. What is necessary is just to remove it from the main body 1 and take it out from the main body 1, and it is easy to remove it, and since a frame is not required, it is particularly easy to wash with water.

As is clear from the description of the above embodiment, the present invention forms the heat exchange element provided at the intersection of the exhaust passage and the air supply passage integrally with the frame of the foamed resin. An integral filter is provided across both the inflow surfaces of the exhaust flow and the supply air, and the filter is hooked and fixed to a hook portion integrally formed on a frame of the foamed resin.
In addition to the need for a single frame, a strong frame is not required, so that the manufacturing cost can be reduced. Further, since the frame is not required, there is an effect that the filter can be easily manufactured, particularly, water can be easily washed.
