Description

[Detailed Description of the Invention] This invention relates to an improvement in the structure for providing a so-called slim type air conditioner with a narrow width and depth, for example, for use on the floor.

The configuration of conventional slim type air conditioners is
As shown in Fig. 2, a machine room 2 is provided at the bottom of the box 1 of the air conditioner, where piping, wiring, etc. (not shown) are carried out, and there is a suction grill 3 at the front of the upper part, and at the back of the machine room 2. An air filter 4 and a heat exchanger 5 are arranged. The blower 6 uses a double-suction Shirotsuko fan, and is placed on the top of the heat exchanger 5. The suction ports 7 of the blower 6 are on both left and right sides when viewed from the front of the air conditioner, and the blower motor 1
A part of 0 is stored in the blower 6, and the blower 6
It is attached to the casing 8 of. A chamber 12 is provided at the top of the blower 6, and air is blown into the room from the chamber 12. In this configuration, since the suction ports 7 of the blower 6 are on both left and right sides when viewed from the front, the depth of the casing 8 becomes large, and therefore the depth of the air conditioner box 1 becomes large. occurred.

This invention was devised to eliminate such drawbacks, and will be explained in detail below with reference to the embodiments shown in FIGS. 3 and 4.

1 is a box of the air conditioner; 2 is a machine room provided at the bottom of the box 1 for piping, wiring, etc. (not shown); 3 is a suction grill provided at the air intake port; 4
5 is an air filter set in the suction grill 3, and 5 is a heat exchanger disposed substantially vertically at the rear of the air filter. 6 and 6' are multi-blade blowers such as two single-suction Sirotskov fans or turbo fans arranged one above the other at the rear of the heat exchanger 5, and the thickness is B when the air volume and blade diameter are the same as before. The dimensions are reduced to approximately 1/2. Reference numerals 7 and 7' denote suction ports of the blower, which have suction air passages spaced appropriately apart from the heat exchanger 5, and are installed substantially parallel to the heat exchanger 5. Reference numerals 8 and 8' denote upper and lower casings of the multi-blade blower, and the width dimension A thereof is formed within the range of the width dimension of the box body 1. Reference numeral 9 denotes a partition plate which is arranged between the upper and lower casings 8 and 8' so as to divide the suction air passage for the upper blower and the suction air passage for the lower blower, each of which has a different suction air passage and outlet air passage, into two independent air passages. It is installed between the front side and the heat exchanger. 10 and 10' are blower motors. Reference numeral 11 denotes an air passage for air blown out from the lower blower 6', and is provided at the rear of the casing 8 of the upper blower 6. 12 is a chamber for mixing the air blown from the upper blower 6 and the lower blower 6' and blowing it out to the front of the air conditioner; 13 is a guide vane for changing the direction of the blown air.

In the air conditioner configured as described above, indoor air is sucked in from the suction grill 3, passes through the air filter 4, heat exchanged with the heat exchanger 5, and the air is sent to the suction ports 7, 7' of the upper and lower blowers. Each of them is sent into chamber 12 along the route indicated by the arrow,
It is mixed and blown into the room. Note that the upper blower 6
The air passage resistance of the suction air passage and the outlet air passage are different between the upper and lower blower 6', and it is difficult to determine the characteristics of the blower. Therefore, by dividing the suction air passage with the partition plate 9, the upper and lower blower The air passages are now independent, making it easier to determine the characteristics of each blower.

As mentioned above, this idea consists of a heat exchanger placed almost perpendicular to the indoor air intake, a heat exchanger placed vertically at the rear of the heat exchanger, and the same air volume and blade diameter as before. Two multi-blade blowers, such as single-suction Sirotskov fans or turbo fans, whose thickness dimension is approximately 1/2, and the suction ports of the multi-blade blowers are arranged approximately parallel to the heat exchanger, and , an upper and lower casing formed within the width dimension range of the box body to form an air path of a multi-blade blower, and a partition that divides the upper and lower suction air paths of the casing into two independent air paths. Since the A dimension of the casing can be used within the range of the width dimension of the box body 1, and the B dimension of the blower is approximately 1 when the blower 6, 6' has the same air volume and the same blade diameter as the conventional one. /2, and the suction area of the heat exchanger 5 can be larger than before, so the depth C of the heat exchanger 5 is reduced accordingly, and as a result, the depth of the box 1 is smaller than the conventional one, making it thinner and easier to install. This has the advantage that the floor space can be significantly reduced, and the characteristics of the upper and lower blowers having different air path resistances can be determined extremely easily.
