Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat exchange type ventilation device for recovering indoor thermal energy discharged to the outside by ventilation.

[0002]

2. Description of the Related Art In recent years, as a means for ventilating a room that is being cooled or heated, dirty air in the room is discharged to the outside, fresh air outside is taken in, and heat is generated between the indoor air and the outdoor air. BACKGROUND ART A heat exchange type ventilation device has been used in which heat is exchanged through an exchanger, and thermal energy of exhausted indoor air is transferred to outdoor air to be recovered indoors.

Conventionally, a heat exchange type ventilator of this type generally has a structure in which a heat exchanger and a lid are integrally provided to prevent the heat exchanger from falling off.

The structure will be described below with reference to FIGS. 4 and 5. As shown in the figure, the indoor side suction port 101 and the indoor side discharge port 102 communicating with the room, the outdoor side suction port 103 communicating with the outdoor, and the outdoor side discharge port 10
4 is provided inside the main body 105 having a rectangular column-shaped heat exchanger 106 in which the stacking direction is vertical, and the bottom surface 107 of the main body 105 is provided with an opening 108 for attaching and detaching the heat exchanger 106,
A lid 109 that is integrated with the heat exchanger 106 that closes the opening 108 is provided with hinge-type fasteners 110 on opposite sides and is attached together with the bottom surface 107.

[0005]

In the structure of such a conventional heat exchange type ventilator, since the lid 109 integral with the heat exchanger 106 is larger than the opening 108, the main body 105.
There is a problem that the opening 108 on the side is difficult to see especially at the time of insertion, and the heat exchanger 106 is difficult to insert at the time of inspection.

The present invention solves the above problems, and a first object of the present invention is to provide a heat exchange type ventilation device which facilitates insertion of a heat exchanger during inspection.

A second object is to hold the heat exchanger by means of a fall prevention metal fitting, and to hold the heat exchanger by providing a hole in the lid slightly larger than the knob portion of the fall prevention metal fitting. .

[0008]

In order to achieve the first object, the heat exchange type ventilator of the present invention has an indoor suction port and an indoor discharge port that communicate with the room, and an outdoor side that communicates with the outdoors. Inside the main body with the suction port and the outdoor outlet,
A square pole-shaped heat exchanger having a vertical stacking direction, an opening for attaching and detaching the heat exchanger on the bottom surface of the main body, a lid for attaching the opening by attachment means, and an L-shaped vertical rod. The fall prevention metal fitting is held in the main body so as to be rotatable in the horizontal direction about the axis, and the horizontal bar of the fall prevention fitting is brought into contact with the lower surface of the heat exchanger so that the heat exchanger can be held.

Further, in order to achieve the second object, the second
Means for bending the horizontal end of the fall-prevention metal fitting downward, and a hole slightly larger than the knob part into which the knob part can be inserted when the lid is attached, To do.

[0010]

According to the present invention, when the heat exchanger for inspection is inserted by the structure of the above-mentioned first means, the heat exchanger is first inserted into the opening on the bottom surface of the main body, and the horizontal bar of the falling prevention metal fitting is heat-exchanged. Since the heat exchanger is held in contact with the lower surface of the heat exchanger and then the lid is attached by the attaching means, the opening can be visually confirmed when inserting the heat exchanger, and the inspection can be performed quickly. Is possible.

Further, according to the structure of the second means, when the heat exchanger is removed for cleaning during inspection, the knob of the fall-preventing metal fitting whose horizontal end is bent downward is inserted into the hole of the lid. Therefore, the heat exchanger is securely held by the horizontal rod of the fall prevention metal fitting, and the lid can be safely removed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS.

As shown in the figure, reference numeral 1 is a main body of a heat exchange type ventilator, which is provided with an indoor side intake port 2 and an indoor side discharge port 3 communicating with the room on one side and communicating with the outside on the other side. An outdoor suction port 4 and an outdoor discharge port 5 are provided.
Further, a heat exchanger 6 having a rectangular prism shape in which the stacking direction is vertical is provided inside the main body 1, and an opening 8 for detaching and attaching the heat exchanger 6 is formed on the bottom surface 7 of the main body 1. A lid 9 is provided smaller than the opening 8 so as to close the portion 8. The lid 9 has a hook 11 provided with one side 10 on the bottom surface 7 of the main body 1.
And the other side 12 is constituted by an attachment means composed of a hinge stopper 13 which is hinged. Further, the L-shaped vertical rod 14 is held in the main body 1 so as to be rotatable in the horizontal direction about an axis, and the L-shaped horizontal rod 16 is brought into contact with the lower surface 15 of the heat exchanger 6 to hold the heat exchanger 6. The fall prevention metal fitting 17 is provided.

Next, a second embodiment of the present invention will be described with reference to FIGS.
This will be described with reference to FIG. As shown in the figure, a knob portion 18 in which the tip of the horizontal bar of the cap 17 is bent downward, and a knob portion 18 into which the knob portion 18 can be inserted into the lid body 9 when the lid body 9 is attached. Slightly larger hole 1
9 is provided.

In the above structure, when the heat exchanger 6 is to be housed, the heat exchanger 6 is inserted into the opening 8 of the bottom surface 7 of the main body 1, and the knob portion 18 of the fall prevention metal fitting 17 is supported while supporting the heat exchanger 6. Then, the horizontal bar 16 of the fall prevention metal fitting 17 is positioned on the lower surface 15 of the heat exchanger 6 to hold the heat exchanger 6.
Next, the lid 9 is attached by the attaching means. in this case,
The knob portion 18 is positioned in the hole 19 provided in the lid body 9 and holds the heat exchanger 6 securely.

Next, when the heat exchanger 6 is inspected and removed for cleaning, the order is reversed. That is, the hinge stopper 13 is removed and the lid 9 is removed, but at this time, it is lowered downward in the hole 19 provided in the lid 9, so that even if the lid 9 is removed, heat exchange is performed. The vessel 6 remains holding the heat exchanger 6 on the horizontal rod 16 of the drop-preventing metal fitting 17. Then, as shown in FIG. 2, the fall prevention metal fitting 17 is pulled out downward while holding the heat exchanger 6 while rotating the grip portion 18 while holding it.

As described above, according to the heat exchange type ventilator of the first embodiment of the present invention, the opening 8 can be visually confirmed at the time of inspection when the heat exchanger 6 is inserted.
Since the knob portion 18 of the drop-out preventing metal fitting 17 is fixed by the lid body 9, the heat exchanger 6 can be securely held.

[0018]

As is apparent from the above-described embodiments, according to the present invention, a rotatable fall-off prevention fitting is provided on the bottom surface of the main body, so that it is difficult to insert the heat exchanger as in the conventional case. In addition, it has an effect that inspection can be performed easily and safely in a short time.
