At this time, in the heat exchanger 1, the supply air flow (supply air) and the exhaust air flow (exhaust air) intersect, and heat exchange and humidity exchange are performed. Any number of exchange elements 1a and 1b can be combined.

As shown in FIG. 2, the heat exchanger 1 is attached to the ventilator 100 in a direction perpendicular to the axis.
That is, the heat exchanger 1 is placed vertically. In other words, the ventilation device 1 or the heat exchange elements 1a and 1b are arranged such that the air inflow surface thereof is perpendicular to the front panel. In other words, the heat exchanger 1 or the heat exchange elements 1a and 1b are arranged such that a vertical line with respect to the supply air flow and the exhaust air flow is perpendicular to the front of the main body casing 9.
It is arranged behind the front panel 10.

FIG. 3 is a side view showing the internal configuration of the ventilation device 100. As shown in FIG. 3, outdoor air is supplied into the room from the panel 10 as shown in a1 and a2, and the room air is sucked from the panel 10 as shown in b1 and b2. Heat exchange device 100 configured as above
In order to increase the heat exchange efficiency, instead of increasing the length of one heat exchange element 1a, a plurality of heat exchange elements 1a are used.
a and 1b may be arranged in parallel. If you do this,
Heat exchange efficiency can be increased while suppressing product height.

FIG. 7 is an exploded perspective view showing the structure of the heat exchanger 1. As shown in FIG. The heat exchanger 1 includes heat exchanger outer frames 13 and 1.

The filter 11 collects dust and dirt contained in the inflow air on the upstream side of the heat exchanger 1, prevents clogging of the heat exchange elements 1a and 1b, and collects dust that enters the room from outside air. It requires regular maintenance.

By mounting the dust collecting filter 11 on the entire air inflow surfaces of the heat exchange elements 1a and 1b, a large collecting area and a reduction in the number of maintenance operations can be expected. When the number of heat exchangers 1 or the number of heat exchange elements 1a and 1b increases, the maintenance time is increased and the maintenance cost is increased. However, a single filter like the filter 11 shown in FIG. The number of filters 11 can be reduced by holding down the air inflow surfaces of the plurality of heat exchange elements 1a and 1b. When a large number of filters are used, the possibility of air leakage between the filters increases. However, if the plurality of heat exchange elements 1a and 1b are covered with a single filter as described above, air leakage may occur. Can be held down.

In the ventilator 100 using the heat exchanger 1 configured as described above, as shown in FIG. 6, the heat exchanger 1 is made up of the heat exchange elements 1a and 1b and the outer frame parts 13 and 14.

FIG. 8 shows the inside of the ventilation device 100 of FIG.
It is a figure for explaining the state at the time of inspection and repair from the room side. At the time of repair, first, the panel 10 of the ventilator 100 installed on the ceiling surface is removed. Next, heat exchanger 1
The cover 15 of the outer frame 13 is removed. Then, the filter 11
Can be easily pulled down. In this way, maintenance of the heat exchanger 1 and the filter 11 incorporated in the ventilation device 100 can be performed easily in a short time.

In this example, the front panel 10 is 1
Although the case of one is shown, the panel on the surface may be divided. Further, a removable lid panel may be provided at that portion of the panel so that the heat exchanger 1 and the filter 11 can be repaired. In short, it is only necessary that the inside of the panel can be inspected and repaired from the front side of the panel, in other words, from the indoor side.

FIG. 5 shows a heat exchanger 1 assembled with a heat exchanger 1.
FIG. 2 is a cross-sectional view of a case where the storage device is housed in the ventilation device 2 and incorporated in the ventilation device 100. Also in this case, as in the case of FIG.
Without removing the front panel 1 shown in FIG.
The filter 11 can be removed, and the filter 11 can be inspected and replaced. The other parts are the same as those in FIG. 4, and a detailed description thereof will be omitted.

It can be performed from below (inside the room). Therefore, it is not necessary to take out the heat exchanger or rotate it in the main body to obtain a cleaning surface. In particular, it is necessary to easily maintain the ventilation device, which is a product mounted at a high place, in a short time, and this embodiment is highly effective in improving such maintainability.

According to this embodiment, the heat exchanger is installed vertically in the axial direction with respect to the main body, and a plurality of heat exchangers are installed in parallel, so that the product height determined by the size of the heat exchanger is obtained. The heat exchange efficiency can be increased while suppressing the heat exchange.

Further, according to this embodiment, a configuration is adopted in which a plurality of surfaces of the heat exchange element are covered with one filter, so that the number of filters can be reduced and maintenance work can be omitted. The filter can be taken out with the heat exchanger fixed to the main body.

Further, according to this embodiment, an opening portion for taking out a filter and for cleaning the heat exchanger is provided in an outer frame portion forming the heat exchanger. Make up. During maintenance, opening and closing the lid makes it possible to check and clean the heat exchanger and the filter, so that work can be performed without moving the heat exchanger.
