Abstract

PURPOSE:To make small the space required for installing a heat exchanger without reducing its heat exchanging performance by installing the heat exchanger opposite to a plurality of suction openings at an inclination to at least one of the suction openings and forming a cabinet of the heat exchanger with separate suction side hollow body and blower room. CONSTITUTION:A heat exchanger 2 sits opposite to suction openings 3a, 3b, and 3c with the heat exchanger and inclined to them at angles 4a, 4b, and 4c respectively. A blower 5 generates an air flow 8 to the suction openings 3a, 3b, 3c, the heat exchanger 2, and an air outlet opening 6. With this arrangement the length of the heat exchanger 2 can be made long and the heat exchanging performance of the heat exchanger 2 opposite to the suction opening 3b is secured by the air flow 8 from the suction openings 3a and 3c, even if the installation space of the heat exchanger becomes small because of the tight contact of the suction opening 3b with a wall of a house, etc., and a larger heat exchanger can be used with an outdoor unit of a specified size.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an air conditioner, particularly an outdoor unit.

Conventional technology Recently, outdoor units of air conditioners have become smaller.

Consideration has been given to reducing the installation space by making it thinner. Therefore, the problem is how to shape the outdoor heat exchanger and how to arrange the blower. To solve these problems, outdoor units as shown in FIGS. 2 and 3, for example, have been put into practical use. Figure 2 shows an L-shaped heat exchanger a installed inside the outdoor unit main body, an air suction port A, and an air suction port A installed on two sides adjacent to it, and the opposite side facing the suction port A. Install the air outlet d in the
c, a heat exchanger a, a blower e, and an air outlet d.

In addition, as shown in Figure 3, a semicircular heat exchanger f is installed inside the outdoor unit body, and air suction ports ``1 m h *'' are installed on three adjacent sides. Even if the heat exchanger f is disposed in close proximity to the heat exchanger f, the heat dissipation effect of the heat exchanger f is not reduced by the air flow from the suction ports q and i.

Problems to be Solved by the Invention However, looking at these two examples, in the case of Fig. 2, when the suction port is placed close to the wall of a house, etc.
The heat dissipation effect of the portion of the L-shaped heat exchanger located at the suction port C was significantly reduced, and there was a drawback that heat could only be radiated from the portion adjacent to the suction port C. Although this problem is solved in FIG. 3, the length of the heat exchanger cannot be increased, so the cabinet must be made larger or higher.

Means for Solving the Problems In order to solve the above-mentioned drawbacks, the present invention has provided a cabinet that is installed opposite to a plurality of suction ports and inclined to at least one suction port, and that a suction-side cavity and a blower are installed inside the cabinet. The heat exchanger is divided into chambers.

Effects of the present invention Due to the above-described configuration, the length of the heat exchanger can be increased in a cabinet of a predetermined size, and even if one suction port is placed close to the wall of a house, etc., the heat exchanger does not absorb any suction. Since it is slanted with respect to the mouth, there is an air flow from other suction ports, so it is possible to provide an outdoor unit of an air conditioner that does not reduce heat exchange performance and can reduce the installation space.

Embodiment FIG. 1 is a top sectional view showing an embodiment of an outdoor unit of an air conditioner according to the present invention. In FIG. 1, reference numeral 1 denotes an outdoor unit main body of an air conditioner, the outer shell of which is formed by a substantially rectangular cabinet.

It is installed at an angle to 3b and 3c. 6 is a blower, suction ports 3a, 3b, 3c, heat exchanger 2. An air flow 8 to the outlet 6 is formed.

With the above structure, the length of the heat exchanger 2 can be increased, and even if the suction port 3b is brought into close contact with the wall 7 of a house or the like to reduce the installation space, the suction port 3a can be kept in place.

The heat exchange performance facing the suction port 3b of the heat exchanger 2 is ensured by the air flow 8 from the heat exchanger 2.

Effects of the Invention As described above, according to the present invention, an outdoor unit for an air conditioner of a specified size can be used. To provide an outdoor unit in which the heat exchanger can be made larger and the heat radiation or heat absorption effect of the heat exchanger can be sufficiently taken without reducing the air circulation effect even if the heat exchanger is placed close to a wall, and the installation space can be reduced. It is also very practical.
