Abstract

(57) [Summary] [Purpose] To provide a smaller and quieter indoor air conditioner unit. [Structure] The casing 1 is composed of a main body 2 and a front cover 3 that covers the main body 2. An air filter 7, an inverted V-shaped heat exchanger 8, and a blower 9 are disposed in order from the top in an air passage 6 connecting an inlet 4 at the top of the housing 1 and an outlet 5 at the lower front. In the lower part of the heat exchanger 8, dew receiving grooves 11 and 12 are provided.
The dew receiving groove 12 is created by integrally molding a rib 13 on the inner surface of the main body 2. The ribs 13 are formed so as to be substantially parallel to the inclined surfaces of the heat exchanger 8. The rib 13 serves to receive condensed water flowing down from the heat exchanger 8 and also serves as a rear tongue of the blower 9.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to an indoor unit of an air conditioner.

0002

[Conventional technology]

The indoor unit housing consists of a main body and a front cover that is removably attached to the main body. The top of this case is equipped with a suction port to take in indoor air. A vent is formed at the bottom of the front to send the heat-exchanged air into the room. It is. The air passage connecting these inlets and outlets has an inverted V shape, for example. When the formed heat exchanger is placed facing the main body side and the front cover, respectively, In both cases, a blower (cross flow fan) is placed below the heat exchanger. and However, condensed water may adhere to the heat exchanger during cooling operation, reducing heat exchange performance. Therefore, defrosting operation etc. are performed to allow the dew condensation water to flow down. , the flowing condensed water is collected in a separate condensation catch groove at the bottom of the heat exchanger, and then released outdoors. The water is drained through a drain pipe leading to the

0003

[Problem that the idea aims to solve]

However, if the heat exchanger is formed in an inverted V shape as described above, condensation water It is also necessary to provide two grooves in the front and back to catch the condensation, and depending on the structure, air ventilation may be required. Do not narrow the passage, impair the flow or distribution of air passing through the heat exchanger, or cause turbulence. This reduces heat exchange performance and generates noise due to turbulent flow. There is a possibility that Therefore, in this invention, we take measures to prevent such situations from occurring. The aim is to provide an indoor unit with no air conditioner.

0004

[Means to solve the problem]

The present invention was made to solve the above problems, and the main body and this main body The housing consists of a front cover that is removably attached to the The main body and the front air passage connect the air inlet formed on the In addition to arranging heat exchangers formed in an inverted V shape so as to face each side cover, , an indoor unit of an air conditioner that has a blower placed at the bottom of this heat exchanger. In this case, condensed water from the heat exchanger disposed on the main body side is poured onto the inner surface of the main body. A rib is integrally formed to receive the blower and also serve as a rear tongue piece of the blower, and It was decided that the tips of the ribs were approximately aligned with the inclination of the heat exchanger.

[0005]

[Effect]

With the above configuration, the ribs that are integrally formed on the inner surface of the main body allow the It can catch the condensed water of the heat exchanger installed, and its ribs are placed behind the blower. It also serves as a side tongue piece, and is shaped so that the tip of the rib is almost aligned with the slope of the heat exchanger. This allows for a wide air passage and improves the flow of air passing through the heat exchanger. It is possible to improve the angle and distribution.

【Example】

An embodiment of the present invention will be described below with reference to the accompanying drawings. Figure 1 is an indoor unit FIG. 2 is a side sectional view showing the inside of the indoor unit. It consists of a main body 2 and a front cover 3 that is detachably attached to the main body 2. The front panel 3a of the bar 3 is pivotally supported at the upper part so as to be freely openable and closable. Also, front cover 3 An indoor air intake port 4 is provided on the top surface, and an air outlet 5 is provided on the lower front surface. There is. An air passage 6 is formed between the suction port 4 and the blowout port 5, and this air Inside the passage 6, it can be moved along the inner surface of the front cover 3 to near the main body 2. A removable air filter 7, a heat exchanger 8 divided into three parts, and a blower (black A blower fan) 9 is installed, and the air heat exchanged by the heat exchanger 8 is sent to the blower. 9 to the air outlet 5, and the direction of the air into the room is adjusted by the wind direction plate 10. It has become.

[0007] The suction port 4 is formed in a slit shape over almost the entire upper part of the heat exchanger 8. The heat exchanger 8 is divided into three parts in the horizontal direction, and two adjacent parts are formed in an inverted V shape. One of them is placed facing the main body 2 side, and the other is placed facing the front cover 3 side. Sending The blower 9 is provided at the center of the lower part of the heat exchanger 8 formed in an inverted V shape. like this If this arrangement is used, the distance difference between the blower 9 and each of the three heat exchangers will be reduced, allowing for better heat exchange. It is possible to improve the distribution of air passing through the housing 8 (wind speed distribution), and also to improve the distribution of air passing through the housing 1. This is because it is possible to downsize.

[0008] In the figure, 11 and 12 are for receiving condensed water flowing down along the heat exchanger 8, respectively. However, the dew catch groove 11 near the front cover 3 is only for catching dew condensation water. It also forms part of the wall of the air passage 6. 13 is placed on the main body 2 side It receives condensed water from the heat exchanger 8 and also serves as a rear tongue piece of the blower 9. This is a rib formed on the inner surface of the main body 2, and its tip extends along the inclined surface of the heat exchanger 8. They extend almost parallel to each other. Therefore, any protrusions that impede airflow etc., and the air passage 6 is kept wide.

[0009]

[Effect of the idea]

If the rib is as explained above, it can serve as both the dew catch groove and the rear tongue of the blower. There are no protrusions that could impede the flow of air through the heat exchanger. Therefore, the air velocity distribution in the heat exchanger is good, and there is no risk of turbulence, so it is quiet and has little noise. You can get a simple indoor unit.
