Abstract

PURPOSE:To prevent short-circuiting of discharge air and intake air in a wall- hanging type indoor unit of an air conditioner, by forming an air intake opening respectively in the top face and one side face of a unit panel, and drawing air into the indoor unit from these intake openings by means of individual fans. CONSTITUTION:An indoor unit of this invention is designed such that air in a room to be air-conditioned is drawn from both of an intake opening 11 formed in the top face of the indoor unit and an intake opening 14 formed in one side face of the indoor unit, then passed through a heat exchanger 17 by means of a fan unit 18, and finally discharged into the room from a discharge opening 13. Here, air drawn from the top intake opening 11 is passed through the heat exchanger 17 by means of a cross-flow fan 20 of the fan unit 18 while air drawn from the side intake opening 14 is passed through the heat exchanger 17 by means of a Sirocco fan 21 of the fan unit 18. Thus, since short-circuiting of air flow between the intake openings and the discharge opening is not caused, it is enabled to exert the required space heating and cooling capacity of an air conditioner.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner and a heater, and particularly to a wall-mounted indoor unit that prevents short circuits between the blown air and intake air, and provides an effective design effect. provide.

Conventionally, in indoor units such as separate type air conditioners and heaters, especially wall-mounted units, as shown in Figures 1 and 2, an indoor air intake port 1 is provided on the front of the panel, and an indoor air intake port 1 is provided directly below the panel. An air outlet 2 is provided on the same front panel, a heat exchanger 3 such as a plate fin type heat exchanger 3, a cross flow fan 4, a filter 5 is provided inside the suction port 1, and a wall-mounted type. An indoor unit 6 is constructed.

However, because the air outlet 2 and the air inlet 1 are located on the same front surface, even if a grille for changing the air outlet angle is provided on the air outlet 2 side, a short circuit may occur depending on the installation conditions of the indoor unit. , there may be cases where sufficient heating and cooling capacity cannot be obtained. Also, in the suction port 1, the grille is arranged vertically or horizontally with a certain spacing, so if the air filter installed immediately inside becomes clogged, the dirt will be noticeable. However, it has disadvantages such as spoiling the aesthetic appearance of the indoor unit and creating a sense of clutter.

The present invention solves the above-mentioned conventional drawbacks, and one embodiment thereof will be described below with reference to FIGS. 3 to 5. Third
In Figures to Figure 5, 9 is a wall-mounted indoor unit, 10 is a wall-mounted indoor unit;
1 is the front panel at the front, 3 pages 11 is an inlet provided on the top surface 12 side, 13 is an outlet provided below the front panel 1o, 14 is a side inlet provided on both sides 15, these In the suction port 11.14,
An air filter 16 shown in FIG. 6 is provided.

17 is a heat exchanger, 18 is a blower, and this blower includes a motor 19, a cross flow fan 20, a sirocco fan 21, and these two fans are coaxially provided on both sides of the motor 19.

In the above configuration, indoor air is sucked into the air inlet 11 on the top surface.
The air is sucked in from both side suction ports 140, passed through a heat exchanger 17 by a blower 18, and blown into the room from an air outlet 13.

At this time, air is sucked in from both the suction port 11 and the side suction port 14; The air is sucked in by a sirocco fan 21 and passed through a heat exchanger 17.

In this way, the present invention provides the air suction ports on the top side and the side side, while the blower is placed on the same axis, and a cross flow fan and a sirocco fan truck are installed, and the top suction air is taken in by the cross flow fan. Since the side air is sucked in by a sirocco fan, passed through a heat exchanger, and blown out from below the front panel, there is no chance of short circuits between the inlet and outlet. The predetermined heating and cooling capacity can be fully demonstrated. Also, since there is only an air outlet on the front panel side,
It does not require the complication of a suction grille, and it is easy to create a design effect.
