Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an air conditioning ventilation fan equipped with a heat exchange element.

BACKGROUND OF THE INVENTION In recent years, air conditioning ventilation fans that exchange heat between indoor air exhaust and outdoor air intake to reduce heat energy ventilation have become popular. By the way, in the conventional air conditioning ventilation fan, as shown in FIG. 5, a space having almost the same shape as the frame 104 that protects the heat exchange element 101 is provided in the air conditioning ventilation fan main body 105, and the heat exchange element mounting frame 102 is installed in the space. The common method was to provide a heat exchange element 101 by attaching a packing 103 or the like to the inner surface of the heat exchange element 101. In addition, 1 in the figure
06 is a blower.

Problems to be Solved by the Invention In the conventional method for fixing a heat exchange element of an air conditioning ventilation fan, the entire side plate of the protective frame 104 that protects the heat exchange element 101 is brought into contact with the gasket 103, so that the side plate of the protective frame 104 is equivalent to or equivalent to the side plate of the protective frame 104. The above gasket 103 is required, and the heat exchange element 101 is
When storing the protective frame 104, there was a problem that the packing 103 got caught and peeled off because there were corners on the sides of the protective frame 104.

The present invention takes into consideration the above-mentioned conventional problems, and aims to provide an air conditioning ventilation fan having a structure that improves the operability of storing the heat exchange element and prevents the packing from peeling off when the heat exchange element is stored. It is something to do.

Means for Solving the Problems In order to achieve the above object, the present invention has developed a method that extends from both sides of the heat exchange element housed inside the air conditioning ventilation fan body, starting from the ridge that is the boundary between the air inlet and the air outlet. is provided with a rib having a tapered shape parallel to the direction in which the heat exchange element is housed in the air conditioning ventilation fan body and whose tip is located at the end of the ridge portion, and guiding the rib inside the air conditioning ventilation fan body. A guide frame is provided that accommodates the heat exchange element in a predetermined position by fitting with the rib, and a packing is attached only to the inside of the guide frame so that the rib comes into contact with and slides on.

Effects The present invention has the above-described configuration, and by guiding the rib portion having a tapered tip at the tip to the guide frame provided on the air conditioning ventilation fan body, the heat exchange element is easily accommodated in a predetermined position, and the guide frame The heat exchange element is securely fixed by the gasket stuck inside, and also prevents the gasket from peeling off when the heat exchange element is stored.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

As shown in the figure, the heat exchange element 1 has a frame plate 10 attached to the ridge, which is the boundary between the air intake port and the air discharge port.
Also, side plates 11 are provided so as to sandwich the air inlet and air outlet from both sides, and these frame plates 10 and side plates 11 are connected by a protective frame 8. The heat exchange element 1 is housed in the air conditioning ventilation fan main body 5 with the frame plate 10 at the top, and ribs 7 are provided on the side plate 11 in parallel to this housing direction. The rib 7 has a tapered shape with tips located at both ends of the frame plate 10. On the other hand, the air conditioning ventilation fan main body 1 includes a partition plate 9 for preventing mixing of the air heat exchanged by the blower 6 and the heat exchange element 1. This partition plate 9 forms a mounting space 2 surrounding the heat exchange element 1. In addition, when storing the heat exchange element 1 inside the air conditioning ventilation fan body 5,
A guide frame 4 is provided that guides the rib 7 and fits into the rib 7, and this fitting holds the heat exchange element 1 in a predetermined position. Inside the guide frame 4, there is a gasket against which the rib 7 slides. 3 is attached. In addition to the inside of the guide frame 4, the packing 3 is attached to the air conditioning ventilation fan body 5.
It is not pasted on the inside.

In the above configuration, when the heat exchange element 1 is housed in the air conditioning ventilation fan main body 5, the rib 7 provided on the side plate 11 is guided to the guide frame 4 of the air conditioning ventilation fan main body 5 and inserted into the mounting space 2. At this time, since the tip of the rib 7 is tapered from the upper and lower surfaces 7a of the rib 7 toward the tip, positioning is extremely easy.
The rib 7 is fitted into the guide frame 4, and the heat exchange element 1 is guided into the mounting space 2 along the guide frame 4. If the heat exchange element is pushed in all the way, the frame plate 10 will be the leading position when stored, so the frame plate 10 will
always comes into contact with the rear surface of the mounting space 2, and an air intake port and an air discharge port located on both sides of the space 2 are reliably partitioned. In addition, the heat exchange element 1 includes a rib 7 and a guide frame 4.
are in a fitted state, so the vertical position is always in the correct predetermined position, and there is no gap between the upper and lower ends of the mounting space 2 and the upper and lower surfaces of the mounting space 2. The air inlet and air outlet located on both sides of the section are also reliably separated. Furthermore, the side plate 11 side of the heat exchange element 1 is also partitioned by the rib 7, the guide frame 4, and the gasket 3, and in this way, the heat exchange element 1 is completely partitioned from the exhaust air and the supply air. Mixing will be prevented. In addition, since the tip of the rib 3 is tapered from the side surface 7b of the rib 7 toward the tip, the rib 7 easily slides without getting caught and does not come off, and the width is small enough to fit with the rib 7. By simply pasting it only on the inside of the guide frame 4, air can be reliably blocked.

As described above, according to the air conditioning ventilation fan according to the embodiment of the present invention, the heat exchange element 1 is housed in the air conditioning ventilation fan main body 5 by moving the rib 7 whose tip is tapered to the guide frame 4.
By guiding it to the right position, it can always be placed in the correct position and easily. Further, the gasket 3 that fixes the heat exchange element 1 and blocks air is attached to the guide frame 4.
The inner size of the rib 7 is sufficient, and the peeling is also limited to the inner size of the rib 7.
This is eliminated by the taper at the tip.

Effects of the Invention As is clear from the above embodiments, according to the present invention, both sides of the heat exchange element housed inside the air conditioning ventilation fan body, starting from the ridge that is the boundary between the air intake port and the air discharge port, A tapered rib is provided at the tip, and a guide frame is provided that guides the rib inside the air conditioning ventilation fan body and stores the heat exchange element in a predetermined position.The rib contacts only inside the guide frame. Since the moving gasket is attached, the heat exchange element can be easily and correctly placed in the air conditioning ventilation fan body, and the air inlet and air outlet at each location are reliably separated, and the material Even with a gasket that requires less labor to attach, it securely secures the heat exchange element and blocks air, and also eliminates peeling of the gasket, which improves the operability of storing the heat exchange element. At the same time, it is possible to provide an air conditioning ventilation fan that has the effect of reliably preventing mixture of exhaust air and supply air.
