Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a window frame air conditioner that blows hot and cold air from the window frame to create an air curtain on the window surface.

BACKGROUND TECHNOLOGY When heating or cooling a room, external heat (solar heat, cross-flow heat) is transmitted into the room through the window, and the temperature inside the room changes due to the influence of the external heat.

For this purpose, there is a known device that blows hot or cold air from the ceiling near the window, a fan coil outlet near the window, a window frame, etc. to create an air curtain to block the external heat.

Problems that the invention aims to solve: Since the system only blows out hot and cold air, the airflow spreads over a wide area near the window, making the person sitting near the window feel uncomfortable. Since the air flow is turbulent, the air curtain effect is reduced and the external heat shielding effect is reduced.

In addition, external heat is freely transmitted through the window frame and transferred into the room, but simply creating an air curtain cannot effectively block the heat transfer.

Means and action for solving the problem A blowout port and a suction port are formed to face each other in the upper horizontal member and the lower horizontal member having hollow portions, and the blowout port is placed in the lower horizontal portion on the air outlet side of the air conditioner. It communicates through the hollow part of the vertical member that communicates with the hollow part of the timber or the hollow part of the lower horizontal member,
The inlet is connected to the air inlet side of the air conditioner through the hollow part of the vertical member that communicates with the hollow part of the upper horizontal member, or the hollow part of the upper horizontal member, so that hot and cold air can flow between the lower and upper horizontal members. It is designed so that it can flow smoothly between the holes and also into the hollow part of the vertical member.

Embodiment FIG. 1 is an overall schematic perspective view, and the window frame 1 is made up of an upper cross member 2, a lower cross member 3, and left and right vertical members 4, 4 made of extruded shapes of metal such as aluminum. , the upper and lower horizontal members 2 and 3 and the vertical member 4 are hollow long members with a rectangular cross section, and the hollow part 2' of the upper horizontal member 2 and the hollow part 4' of the vertical member 4 are in communication with each other. The hollow part 3' of the horizontal member 3 is closed by the inner wall 4a of the vertical member 4, and an air outlet 5 is formed in the upper wall 3a.
A suction port 6 is formed in the shape of a slit in the lower wall 2a of the upper cross member 2.

The lower end of the vertical member 4 protrudes below the lower horizontal member 3, and an outlet 7 is formed in the inner wall 4a, and the outlet 7 communicates with the air inlet of the air conditioner 9 via a duct 8. communicates with the hollow portion 3' of the lower cross member 3 through a duct 10.

FIGS. 2 and 3 are detailed longitudinal and cross-sectional views, in which a window frame 1 is fitted with glass 11, and a blind 12 is attached to the indoor side.

The above-mentioned inlet 6 of the upper cross member 2 and outlet 5 of the lower cross member 3 are located between the glass 11 and the blind 12.

Furthermore, pipes 13 through which hot and cold water flow are arranged in each of the hollow parts 2', 3', and 4'.

Because of this, the hot and cold air discharged from the air conditioner 10 flows from the outlet 5 of the lower horizontal member 3 to the upper horizontal member 2.
At the same time, the air inlet of the air conditioner 10 sucks the air inside the hollow part 4' of the vertical member 4 through the duct 8 and the outlet 7, so the hot and cold air blown out is blown out to the upper horizontal member 2. The air is blown in from the suction port 6, passes through the hollow part 2' of the upper horizontal member 2 and the hollow part 4' of the vertical horizontal member 4, and returns to the air inlet of the air conditioner 9.

Therefore, the flow of hot and cold air becomes smooth and does not diffuse, and the upper horizontal member 2 and vertical member 4 themselves can be heated and cooled.

In the above embodiment, a coil is provided inside the air conditioner 9 to provide heating and cooling functions, but as shown in FIG. It may be installed outdoors and connected to the air conditioner 9 via piping 24.

In addition, as shown in FIG. 5, the air conditioner 9 is housed in the ceiling, its outlet is connected to the upper part of the hollow part 4' of the left and right vertical members 4 by a pair of pipes 25, and the inlet is connected to the upper horizontal member by a pipe 26. It may also communicate with the hollow portion 2' of No. 2.

In this case, the hollow part 2' of the upper cross member 2 and the hollow part 4' of the vertical member 4 are cut off, and the hollow part 3' of the lower cross member 3 and the hollow part 4' of the vertical member 4 are communicated with each other.

Effects of the invention Hot and cold air is blown out from the air conditioner 9 through the outlet 5, and the blown out hot and cold air is sucked in through the inlet 6, so there is no hot or cold air between the lower cross member 3 and the upper cross member 2. It flows smoothly and does not spread or become disordered.

Therefore, the person near the window does not feel the airflow of hot or cold air, and the air curtain effect is increased to effectively block external heat.

In addition, hot and cold air is supplied to the hollow parts 2' of the upper and lower cross members 2, 3,
3' and the hollow part 4' of the vertical member 4, the upper and lower horizontal members 2, 3 and the vertical member 4 themselves can be heated and cooled, and external heat can be prevented from being transmitted into the room through them.
