[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor unit of an air conditioner, and more particularly, to means for facilitating the attachment and detachment of an air filter of the indoor unit and for downsizing the indoor unit.

[0002]

2. Description of the Related Art A housing of an indoor unit of an air conditioner is composed of a main body and a front cover detachably mounted on the main body, and an upper portion of the housing has a suction for taking in indoor air. A mouth is provided, and an outlet for discharging heat-exchanged air into the room is formed in a lower part of the front surface.
In an air passage connecting the suction port and the air outlet, an air filter detachably provided near the suction port and an inverted V-shaped heat split and formed so as to face the main body side and the front cover, respectively. There are an exchanger and a blower (cross flow fan) disposed below the heat exchanger, and the air that has been heat-exchanged by the heat exchanger is sent into the room by the blower. Further, a wind direction plate for adjusting the direction of the wind is provided at the outlet.

[0003]

When the heat exchanger is divided into an inverted V-shape as described above, the divided surface is open and the fins constituting the heat exchanger are present. As a result, air that is not heat-exchanged passes therethrough, which causes a problem that the heat exchange rate is reduced. on the other hand,
The air filter bows from the rear of the front cover to the rear of the main unit along the lower part of the housing's suction port so that it can be attached and detached when the front cover that is pivotally supported at the top of the housing is opened and closed. However, if there is no space between the detachable air filter and the heat exchanger, there is a problem that the air filter contacts the split surface of the heat exchanger and is broken. Therefore, in the past, the gap between the upper end of the heat exchanger and the air filter was set to be large. However, in recent years, a smaller indoor unit has been required, and the space between the heat exchanger and the air filter as described above has been required. Even gaps can no longer be ignored. Therefore, an object of the present invention is to solve these problems and to provide a more compact indoor unit of an air conditioner.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and at least attaches and detaches an air passage connecting an intake port at an upper portion of a housing and an air outlet at a lower portion of the housing. A flexible air filter, and an inverted V divided so as to face the front and back surfaces of the air passage, respectively.
In an indoor unit of an air conditioner provided with a heat exchanger having a V-shape and a blower for sending out heat-exchanged air, a shield plate provided with a guide for guiding the air filter on a division surface of the heat exchanger Was decided.

[0005]

According to the above construction, since the guide plate for guiding the air filter is provided on the shield plate at the upper end surface of the heat exchanger, the slippage when the air filter is attached and detached is improved. As a result, the size between the ceiling of the housing and the heat exchanger can be reduced, thereby reducing the size of the indoor unit and preventing the passage of air that is not heat-exchanged. Therefore, the heat exchange rate can be increased.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a perspective view showing the appearance of the indoor unit, and FIG. 2 is a side sectional view showing the inside of the indoor unit. The housing 1 comprises a main body 2 and a front cover 3 which is detachably mounted on the main body 2. Front panel 3a of front cover 3
Is pivotally supported at the upper part so that it can be opened and closed. In addition, suction ports 4a and 4b for room air are provided in an upper portion of the front cover 3,
An outlet 5 is formed in the lower part of the front surface. Inlet 4a,
An air passage 6 is formed between the air outlet 4b and the air outlet 5. In the air passage 6, a detachable air filter 7 which can be moved toward the main body 2 along the inner surface of the front cover 3 is provided. , A heat exchanger 8 divided into three parts, and a blower (cross flow fan) 9 are arranged, and air exchanged by the heat exchanger 8 is sent to the outlet 5 by the blower 9, and the wind direction to the room is changed. It is adapted to be adjusted by the wind direction plate 10.

The heat exchanger 8 is divided into three parts in the horizontal direction, and two adjacent ones are formed in an inverted V-shape. One of them is arranged toward the body 2 and the other is arranged toward the front cover 3. ing. The blower 9 is provided at the lower center of the heat exchanger 8 formed in an inverted V shape. With such an arrangement, the distance difference between the blower 9 and each of the three heat exchangers is reduced, so that the distribution of air passing through the heat exchanger 8 (wind speed distribution) can be improved, and the housing 1 Can be reduced in size.

In the figure, reference numerals 11 and 12 designate dew receiving grooves for receiving dew water flowing down along the heat exchanger 8, respectively. The dew receiving groove 11 near the front cover 3 only receives dew water. Instead, it also forms part of the wall of the air passage 6. Reference numeral 13 denotes a part of the dew receiving groove 12, which is a rib formed on the inner surface of the main body 2 so as to receive the dew water of the heat exchanger 8 disposed on the main body 2 side and also serve as a rear tongue of the blower 9. , The tip of which extends substantially parallel to the inclined surface of the heat exchanger 8. Therefore, there is no protrusion that obstructs the flow of air, and the air passage 6 is in a state of being widely secured.

By the way, in the heat exchanger 8 formed as shown in the figure, the divided surface is opened and the air which is not exchanged with the heat passes therethrough, and the heat exchange rate is lowered. Although it is necessary to provide the plate 14, in this embodiment, the shield plate 14 has a shape as shown in FIGS. These are all resin molded products,
The heat exchanger 8 is formed so as to be covered along the dividing surface of the heat exchanger 8 formed in an inverted V-shape. Stop pieces 16 are provided on both sides at predetermined intervals. Since these locking pieces 16 are inserted into the gaps between the fins 17, the thickness is also limited and is about 1 mm.

In the shield plate 14 shown in FIG.
Both end faces are formed downward and the fins 17 of the heat exchanger 8 are formed.
This portion can serve as a guide for guiding the air filter 7 when the air filter 7 is attached and detached. The shield plate 14 shown in FIG. 4 does not have a portion that covers the corners of the fins 17 as in the former case, but instead has fan-shaped ribs 18 provided at predetermined intervals at the upper portion. Will play a role. If such a guide for guiding the air filter is provided above the heat exchanger 8, the air filter 7 can be attached and detached without being caught on the divided surface of the heat exchanger 8, so that the gap between the air filter 7 and the heat exchanger 8 is increased. There is no need to take it, and the height of the housing can be reduced accordingly.

[0011]

[Effect of the Invention] The shield plate as described above is inverted V
If it is installed on the split surface of the heat exchanger divided into
There is no wasted air passing through the split surface of the heat exchanger, and the heat exchange rate is improved, and the upper part of the shield plate serves as a guide for guiding the air filter, so the air filter is caught by the heat exchanger. Since the gap between the air filter and the heat exchanger can be reduced without being damaged, the height of the housing can be reduced accordingly, and a more compact indoor unit can be provided.
