Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner equipped with an outside air intake device.

In general, it is considered necessary to introduce fresh outside air into the room to prevent air pollution from combustors such as gas cooking stoves. If you do,
For example, when heating the room, the indoor temperature drops, making it impossible to provide comfortable heating.

To address this problem, a method has been proposed in which outside air is introduced through the heat exchanger of an air conditioner.

However, this method has the following problems.

In other words, normal air conditioners control the blower in stages of high speed, medium speed, low speed, and stop depending on the indoor temperature, or steplessly control the blower, and the blower does not operate when the indoor temperature reaches a predetermined temperature. Therefore, even if it is necessary to introduce outside air while the combustor is in use, the blower may stop operating if the room temperature has reached the specified temperature.
The problem is that sufficient intake of air may not be possible.

This invention was made in view of the above points, and the introduction of outside air through the heat exchanger, which is required during the use of the combustor, can be used to operate the exhaust system of the combustor or the ventilation system attached thereto. The above problem is solved by forcibly controlling the operation of the blower of the air conditioner.

Hereinafter, details of the present invention will be explained based on embodiment figures.

1 and 2, 1 is the main body of the air conditioner;
2 and 3 are indoor air inlets and outlets provided on the front side of the upper and lower parts of the main body 1, and 4, 5, and 6 are in the main body 1 between the inlet 2 and the outlet 3. A filter, a blower, and a heat exchanger are shown arranged sequentially from above, 7 is a duct connection port for outside air intake provided on the back side of the main body 1 to face the suction port 2, and 8 is a combustor (not shown). 9 is a damper device that selectively opens and closes the suction port 2 and the duct connection port 7 in response to the stoppage of the operation of the exhaust device (not shown) of a ventilation device such as a range hood, which is linked to Shows a rotary switch for

Next, the control operation will be explained based on the implementation diagram of the control circuit of the present invention shown in FIG.

First, during normal heating operation, operate the rotary switch 9 depending on the indoor temperature to select "strong,""medium," or "low."
By closing any contact of the blower motor 51, the relay 10
is operated via the contact 101a of the contact piece 101.

At this time, the other contact piece 102 of the relay 10 is connected to the contact 102a.
Since the damper motor 81 is deenergized because it is connected to the side, the damper device 8 closes the duct connection port 7 side and opens the suction port 2 side, so the indoor air sucked through the suction port 2 is The heat exchanger 6 exchanges heat with hot water, and the hot air is blown into the room from the outlet 3.

On the other hand, when the combustor is operated, the switch 11 activated in response to this closes and drives the exhaust device drive motor 12 of the ventilation system, and the relay 13 is energized to close its contact piece 131. Therefore, the relay 13 may be energized by eliminating the parallel connection of the motor 12, and the switch 11 may be activated in response to one drive of the motor 12.

), the relay 10 is energized, and one contact piece 101 is connected to contact 1
The blower motor 51 is switched from the 01a side to the contact 101b side, and the blower motor 51 operates via the "strong" contact, and at the same time relay 1
The other contact piece 102 of 0 is switched to the contact 102b side,
The damper motor 81 starts operating and closes the suction port 2 side.

Therefore, outside air is sucked in through the duct connection port 7, turned into warm air by the heat exchanger 6, and blown out from the outlet 3, providing comfortable heating at the same time.

Also, if the indoor temperature rises, turn off the rotary switch 9.
In a state where the blower 5 is stopped by operating the contact,
Even when the exhaust device of the ventilation system is activated, the blower motor 51 is set to "strong" by the contact 101b of the contact piece 101 of the relay 10.
The contact 102b of the contact piece 102
Since the damper device 8 opens the duct connection port 7,
As mentioned above, sufficient outside air is taken in to provide comfortable heating.

In addition, in the above embodiment, when the combustor is operated, the blower motor 51 is operated via the "strong" contact, but the same can be done by connecting it to other contacts depending on the required amount of outside air. be.

Further, in the above embodiment, an air conditioner of a top-breathing, bottom-blowing type was described, but it can also be applied to a bottom-breathing, top-blowing type of air conditioner, or for cooling purposes.

As described above, in this invention, the fresh outside air necessary for combustion is exchanged with the heat exchanger and then brought into the room by the outside air intake device that operates in accordance with the operation of the exhaust device in the incinerator or ventilation system. , it is possible to perform comfortable heating or cooling, and even if the operation of the air conditioner, that is, the operation of the blower is stopped, the blower can be forced to operate according to the operation of the exhaust device of the combustor or ventilation system. This has the effect of allowing sufficient outside air to be taken in.
