Description

[Detailed description of the invention] This invention, in a heat pump type air conditioner, opens the inlet at the front of the housing only during cooling operation, and uses a stopper to prevent the downward rotation of the wind direction plate of the outlet. death,
The present invention relates to an air conditioner that prevents air short-circuits due to the opening of the suction port on the front side of the housing, and improves the cooling capacity.

Conventional air conditioners have an indoor chamber and an outdoor chamber inside the housing, and the indoor chamber and the outdoor chamber are connected to each other through an inlet and an outlet, and the indoor air is drawn into the room from the indoor inlet. Outdoor air is sucked into the side chamber and blown into the room from the indoor air outlet. Outdoor air is sucked into the outdoor room from the outdoor air intake and is blown outside from the outdoor air outlet, thereby heating and cooling the room.

By the way, in this type of air conditioner, the indoor air intake port is not formed on the front surface of the casing, but is formed on two sides on both sides of the casing, and the indoor air outlet is formed on the upper front surface of the casing. .

This is because when the air conditioner is in heating operation, the vertically rotatable wind direction plate installed at the indoor air outlet is placed in the lowest position, so the indoor air intake is formed on the front of the housing. If the indoor air outlet is exposed to air, the air from the indoor air outlet will be blown out directly in front of the indoor air inlet, and this blown air will be sucked directly into the indoor air chamber through the indoor air inlet, creating the risk of causing a so-called air short. In order to prevent this air short circuit, indoor suction ports are formed only on two sides of the housing.

However, this type of air conditioner has the same specifications as mentioned above even during cooling operation, and indoor air is drawn into the indoor room only from the indoor air intake ports on only two sides on both sides of the housing. As a result, the temperature distribution of the heat exchanger disposed inside the housing deteriorates, resulting in loss in cooling, and the drawback is that the original cooling capacity is not exhibited.

This idea was made keeping in mind the above-mentioned drawbacks of the conventional method, and the indoor air inlet is also formed on the front side of the housing, and the indoor air inlet on the front side is opened only during cooling operation, and the air inlet is opened on the lower side of the wind direction plate. This device is designed to prevent rotation, and this device will be explained in detail with reference to a drawing showing one embodiment of the device.

Next, the operation of the above embodiment will be explained.

First, during heating operation, the slide plate 26 is slid to the right by the handle 31, and the suction hole 25 of the grill plate 24 is closed by the slide plate 26.

Then, the fan motor 5 is operated to operate both ventilation fans 6.
8, the indoor air sucked in from the indoor suction ports 16 on both sides of the housing 1 due to the rotation of the indoor blower fan 6 exchanges heat with the indoor heat exchanger 10.
After cooling, it is blown into the room from the indoor air outlet 18,
Outdoor air sucked in from the outdoor suction port 19 by the rotation of the outdoor ventilation fan 8 is cooled in the outdoor heat exchanger 11 and then blown out from the outdoor air outlet 20, thereby heating the room. .

At this time, the stopper 28 is located below the hole 30 of the wind direction plate 22, and when the wind direction plate 22 is rotated downward as shown in FIG. As shown by the one-dot chain line or the two-dot chain line, the wind direction plate 22 can be rotated downwardly, while the front indoor air intake port 17
Since the airflow direction plate 22 is closed, no air short occurs and the wind direction plate 22 can freely move up and down.

In addition, during cooling operation, the handle 31 is moved to the left, the slide plate 26 is slid to the left, and the suction hole 2 of the grill plate 24 is moved to the left.

8, the indoor air sucked in from the indoor side suction port 17 on the front side of the housing 1 and the indoor side suction ports 16 on both sides by the rotation of the indoor side ventilation fan 6 is cooled in the indoor side heat exchanger 10. Then, the air is blown into the room from the indoor side air outlet 18, and the outdoor side suction port 1 is blown out by the rotation of the outdoor side blower fan 8.
After the outdoor air sucked in from the outdoor air outlet 9 exchanges heat with the outdoor heat exchanger 11 to cool the outdoor heat exchanger 11, it is blown outside from the outdoor air outlet 20, thereby cooling the room. .

At this time, since the stopper 28 is in a position to prevent the downward rotation of the wind direction plate 22, the downward direction of the wind direction plate 22 is suppressed, as shown by the dashed line in FIG. Air shorts caused by the opening of the suction port 17 are prevented.

Therefore, the grill plate 24 is disposed at the indoor suction port 17 on the front surface of the housing 1, and the suction hole 2 of the grill plate 24 is
A slide plate 26 is slidably provided to close the air outlet 5, and the indoor suction port 17 is opened and closed by sliding of the slide plate 26, and the wind direction plate 22 is rotated downward by the stopper 28 when the indoor suction port 17 is opened. Therefore, the suction of indoor air into the indoor chamber 3 during cooling operation can be prevented by sliding the sliding plate 26 through the indoor suction ports 16° and 17 on the three sides.
This makes it possible to improve the temperature distribution of the heat exchanger and greatly improve the cooling capacity.At the same time, the stopper 28 integrated with the slide plate 26 allows prevent the downward rotation of the
Air shorts caused by the opening of the indoor suction port 17 at the front can be prevented.

As described above, according to the air conditioner of this invention, in an air conditioner in which an indoor chamber and an outdoor chamber are provided in the housing, and an inlet and an outlet are communicated with each chamber, the inlet of the indoor chamber is connected to the inlet of the indoor chamber.
