Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an energy-saving separate room air conditioner capable of underfloor ventilation while improving cooling efficiency.

[0002]

2. Description of the Related Art In order to prevent global warming, thermal power generation using a large amount of fossil fuel also tends to be suppressed.

Therefore, there is an urgent need to reduce the power consumption of an air conditioner (air conditioner), which accounts for a large amount of power consumption in the summer.

In such a case, the conventionally adopted method increases the efficiency of the heat exchanger of the indoor / outdoor unit. Increase the efficiency of compressors and motors. Further, a method of reducing power consumption has been used by devising the blowing direction of the cold air, the blowing method, or the setting method of the temperature so that it feels cold without lowering the temperature too much.

[0005]

However, since the method for increasing the efficiency of the components such as the heat exchanger, the compressor and the motor as described above is a method which has always been performed conventionally, a reliable energy saving effect can be achieved. However, it is difficult to obtain a epoch-making improvement effect, and there is a problem that the energy saving effect on the improvement cost will deteriorate in the future.

Further, for example, there are problems that the size of the outdoor unit becomes large in order to improve the efficiency of the heat exchanger, and that the open space around the outdoor unit needs to be made large in order to improve ventilation. It can occur.

Therefore, an object of the present invention is to make it possible to save more energy by a method other than improving the constituent parts, in which case the size is large and the installation method is not so restricted. To do so.

[0008]

In order to solve the above problems, the present invention employs a structure in which the intake surface of the outdoor unit of the separate room air conditioner is formed as an intake cylinder that is inserted under the floor of the house. is there.

With this structure, the outdoor unit sucks in air under the floor via the intake cylinder inserted under the floor to perform heat exchange. At this time, the temperature under the floor is kept lower than the outside air temperature in summer due to the heat insulation effect of the house. Therefore, the outdoor unit that sucks in this air can improve thermal efficiency and can be expected to save energy. Further, since the air under the floor is sucked in, the outdoor unit does not need a surrounding space, and since the underfloor is isolated from the outside air by the foundation, a short circuit (circulation of exhaust gas to the intake side) does not occur.

At this time, if the structure in which the heat exchanger of the outdoor unit is arranged in the intake cylinder is adopted, the outside air is sucked by the negative pressure sucked through the heat exchanger, so that the wind noise when sucking is reduced. it can. Further, if a heat exchanger is provided in the intake cylinder and the fan is provided inside the outer main body, vibration and rotation noise of the fan are less likely to be transmitted to the room through the floor, which is effective in reducing noise.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the energy-saving separate room air conditioner of this embodiment is improved by using an outdoor unit 1 of the conventional air conditioner (for example, including a compressor, a heat exchanger, an exhaust fan, and a control circuit). In addition, the intake surface 2 of the outdoor unit 1 is formed into an intake pipe 3 that is inserted under the floor of the house (in this embodiment, an improved version of the conventional outdoor unit 1 is shown. , It doesn't matter if it is a newly constructed one).

That is, the intake surface 2 of the outdoor unit 1 has a structure in which a lid member 4 provided with an intake cylinder 3 is attached as shown in FIG.

The cover member 4 covers the entire surface of the intake surface 2, and can seal the portion other than the intake cylinder 3 protruding from the member surface (in this embodiment, the intake surface is formed on the side surface). If not, but if the side is provided with an intake surface, also configure this to block).

The intake cylinder 3 is formed in accordance with the height of the ventilation port 5 provided in the standard foundation b of the house, and its height and size are appropriately determined.

Further, in this embodiment, the lid member 4 is attached using the case of the outdoor unit 1 or the screw hole provided in the frame of the case, and by doing so, the lid member 4 is commercially available. Can be installed in an air conditioner for easy retrofitting. At this time, if a plurality of intake cylinders 3 having different positions and sizes are prepared and can be selected, it can be easily applied to the ventilation port 5 of the non-standard foundation b.

On the other hand, in this embodiment, the intake cylinder 3 has the structure shown in FIG.
As shown in, an intake fan 6 is provided at the tip.
The intake fan 6 is arranged at this position instead of the exhaust fan (exhaust surface side) provided in the conventional air conditioner outdoor unit 1, and is connected to the control circuit of the air conditioner. Therefore, the control circuit controls ON / OFF and rotation speed.

In the figure, reference numeral 7 is a heat exchanger, and reference numeral 10 is a compressor.

Although the intake fan 6 is provided in the intake cylinder 3 in this embodiment, the present invention is not limited to this. The exhaust fan provided in the conventional air conditioner outdoor unit 1 may be used as it is. In this case, the efficiency is considered to be slightly lower than that of the intake fan 6, but the refurbishing point can be minimized. Therefore, if such an adapter is manufactured, there is an advantage that it can be applied to the currently used one.

This embodiment is constructed as described above, and the outdoor unit 1 has the intake cylinder 3 as a base b as shown in FIG.
And put it under the floor. For this insertion, the ventilation port 5 of the foundation b may be used, or if there is no ventilation port 5, the foundation b
You may provide a through-hole in. At this time, for example, the intake cylinder 3
If a part of the is formed by a flexible pipe or the like so that it can be bent, errors during construction can be absorbed and installation can be simplified.

If part of the intake pipe 3 is replaced according to the size of the ventilation port 5 of the foundation b as shown in FIG. This is convenient because it is not necessary to widen or narrow it in accordance with the height and the base b is not damaged. Further, as shown in FIG. 2B, if the intake pipe 3 can be extended by a flexible pipe or the like, it is not restricted by the installation place.

When the outdoor unit 1 installed in this way is connected to the indoor unit 8 to perform a cooling operation, the outdoor unit 1 will move to the intake cylinder 3
The air under the floor is sucked in through to exchange heat. At this time, the temperature under the floor is kept lower than the outside air temperature in the summer due to the heat insulating effect of the house above it, so that the thermal efficiency of the outdoor unit 1 that sucks in this air can be improved. Also,
Since the underfloor air is exhausted by the intake of the outdoor unit 1, for example, as shown in FIG. 3, it is expected that the outside air is circulated to dry the moist underfloor to prevent the occurrence of termites and to prolong the life of the house. it can.

At this time, since the outdoor unit 1 sucks in the air under the floor, a space for intake is not required in the surroundings. Also, since the underfloor is isolated from the outside air by the foundation b, a short circuit (exhaust of exhaust gas to the intake side) does not occur. Therefore, as shown in FIG. 1, it can be installed even if the space between it and the adjacent house 9 is small, so that it can be installed anywhere.

A second embodiment is shown in FIGS. 4 (a) and 4 (b). In the air conditioner of this form, the heat exchanger 7 is provided in the intake pipe 3 of the outdoor unit 1.

Therefore, as shown in FIG. 4B, the fan 6 in the main body takes in underfloor air through the heat exchanger 7 by the negative pressure of the fan 6.

By doing so, the outside air is sucked in with a negative pressure, so that there is an effect that the wind noise when sucking can be reduced. Also, since the fan 6 is provided inside the outer body,
Vibrations and rotation sounds of the fan 6 are less likely to be transmitted to the room through the floor, which is effective in reducing noise.

Although the fan 6 is provided in the main body in this embodiment, the present invention is not limited to this. For example, it may be provided inside the intake cylinder 3 inside the heat exchanger 7. In this way, although the noise is increased, the flow velocity in the intake cylinder 3 can be accelerated, so that the cooling efficiency can be increased.

Other configurations, operational effects, and other aspects are the same as those of the first embodiment, and therefore their explanations are omitted.

A third embodiment is shown in FIGS. 5 (a) and 5 (b). In this form, the intake cylinder 3 provided with the heat exchanger 7 is formed in a cylindrical shape, and by doing so, a circular hole (a hole in the second embodiment that is easy to make a hole in the foundation at the time of mounting). (Compared to a rectangle), workability can be improved.

Other configurations, operational effects, and other aspects are the same as those of the first and second embodiments, and therefore their explanations are omitted.

In the embodiment, for example, a small-sized household air conditioner (about 1 horsepower) is described, but the invention is not limited to this. Obviously, it can be applied to commercial air conditioners.

[0032]

As described above, according to the present invention, more energy saving can be achieved by a method other than the improvement of the components. Also, because it does not cause a short circuit, it is not restricted by the installation location.
