Description

[Detailed Description of the Invention] This invention is an invention related to a window unit equipped with an intake/exhaust device and a window shutter.

Normally, ventilation in a room is done by opening and closing windows. However, in the winter, for example, opening the windows allows the hot air to be exhausted to the outside, bringing in fresh but cold air indoors, and then reheating the room. The second problem is that people inside the room feel cold while the windows are open, and they are noisy when it is noisy outside. Ta.

Furthermore, when separately attaching a shutter to an existing window, the installation work often involves modifying the area around the window mounting frame, which is complicated and expensive.

In view of these circumstances, the present application aims to eliminate the above-mentioned defects by developing a unit that integrates a wind-up type shutter into a window frame with a ventilation device that takes in and exhausts heat-exchanged air.

The window unit according to the present application will be explained in detail below.
Its structure is such that a casing 1 is provided at the top of a window frame 10, the inside of which is divided into two upper and lower chambers 11a and 11b, the upper chamber 11a is further divided into left and right, and the lower chamber 11b is provided with a winding system that rises and lowers on the outside of the window. A type shutter 12 is housed inside so that it can be wound freely, and an outside air intake port 3, a fan 4, and an air supply port 5 are provided on either the left or right side of the upper chamber 11a, and an exhaust air intake port 6, a fan 7 is provided on the other side.
and an exhaust port 8, and a heat exchanger 2 is installed inside the upper chamber 11a of the housing 1 so that the coil 2A passes through the left and right partitions, and outside air or indoor air is passed through the heat exchanger 2. It is characterized in that it is supplied indoors or discharged outside.

Next, a preferred embodiment of the present invention will be illustrated and further described.

FIG. 1 is a perspective view of the present invention seen from the indoor side. Old indoor air is taken in through the exhaust intake port 6, and fresh air from outside is supplied through the air supply port 5.

In the illustration, 10A is a window glass, which is a type that can be opened and closed like a door. Also 1
3 is a bar that operates the elevation of the shutter 12;
By rotating this, the shaft 14 (third
(see figure) rotates, and the shutter moves up and down.

FIG. 2 is a perspective view of the present invention seen from outside, where fresh air is taken in through the outside air intake port 3 and old air is exhausted through the exhaust port 8. Note that the shutter 12 moves up and down a guide 15 outside the window glass 10A.

FIG. 3 is a cross-sectional view of the exhaust side provided on the right side of the upper chamber 11a of the housing 1 in the ventilation system of the present invention, in which old air entering from the exhaust intake port 6 passes through the fan 7. After providing heat to the heat transfer wall of the coil 2A of the heat exchanger 2 installed in the upper chamber 11a of the housing 1, the heat is exhausted.

Although not shown, the ventilation system on the air supply side provided on the left side of the upper chamber 11a of the housing 1 has a similar structure, and fresh air from the outside is taken in through the inlet 3 and exhausted through the heat exchanger 2. absorbs the heat provided by the air and supplies it indoors as warm, fresh air.

Further, the coil 2A may be of an endless type filled with refrigerant, for example.

The structure of the window unit according to the present application is as described above, and the structure provides the following functions and effects.

In the present invention, the lower chamber 11 of the casing 1 above the window frame 10
Since the shutter 12 is installed inside the shutter 12 so that it can be freely wrapped around the upper chamber 11a, and the ventilation system is provided in the upper chamber 11a, air can be supplied and exhausted with the window closed or the shutter lowered. During ventilation, fresh air can be constantly supplied indoors while external noise is insulated.

In addition, the ventilation system for the upper chamber 11a is a heat exchanger in which the upper chamber 11a is separated into left and right parts, one of which is used as an exhaust part, and the other part is used as an air supply part, and a coil 2A passes through the left and right partitions. 2 is installed inside the fan 7, the indoor air entering from the exhaust intake port 6 provides heat to the electric heating wall of the coil 2A of the heat exchanger 2, and is then exhausted to the outside. The outside fresh air taken in from the outside air intake port 3 by 4 is sent to the coil 2A provided by the exhaust air in the heat exchanger 2.
This allows the conductive heat to be absorbed and supplied into the room, making it possible to ventilate the room without escaping the warm air, thereby minimizing energy consumption for ventilation. This provides a comfortable environment for residents without causing a sudden drop in indoor temperature due to the intake of cold air during ventilation.

Furthermore, since the present invention has a built-in shutter, no installation work is required, and the shutter can be raised and lowered from inside the room with the windows closed, making it extremely convenient.

Furthermore, since the window frame, ventilation system, and shutter are integrated in the present invention, it can be easily installed on existing windows, and its utility value is high.
