Then, the angle (not shown) is bridged over connecting pieces 4c and 5c, and the casing 17 is hermetically attached to the partition plate 19.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner in which an evaporator, a condenser, a fan thereof, a fan casing for the fan, a motor, etc. are constructed in one housing.

Such air conditioners, for example window type air conditioners.

In an air conditioner such as a spot cooling fan, a molded heat insulating material such as styrofoam is generally used for the fan casings of the evaporator fan and condenser fan, since it prevents sweating and is lightweight. However, although molded heat insulators have good heat insulation properties, are lightweight, and are easy to assemble, they are not strong, so they cannot be assembled by inserting them into partition plates, support plates, etc., or fixing them using fixing members. It has been adopted. On the other hand, since the motor for a fan is relatively heavy and is a source of vibration, an angle for supporting the motor is separately provided and fixed. In other words, although air conditioners that are constructed using molded heat insulating material support plates, fixing members, and angles of the motor reservoir are intended to be lightweight, they are not lightweight, and moreover, they have a large number of components. This was very disadvantageous in terms of cost.

In view of the above, the present invention has been made with the aim of providing an air conditioner that can reduce weight and cost without compromising necessary functions such as sweat prevention.An example of the present invention is attached below. This will be explained according to the drawings.

In the figure, 1 is the main body of an air conditioner capable of so-called spot air conditioning, which blows out cold air and hot air at the same time. This main body 1 has a pair of gate-shaped pillars 4 and 6 erected at the corners of a bottom plate 3 provided with casters 2, and the outer periphery of the pillars 4 and 6 is formed by an outer plate 6 having a U-shaped cross section and a front panel 7. It covers the outer shell. The outer panel 6 has indoor air intake ports 8 at opposing positions.
8', a hot air outlet 9 is provided at a position adjacent to the inlet 8', and a cold air outlet 10 is provided at the front panel 7 adjacent to the inlet 8.

Inside the main body 1, a compressor 11 on the bottom plate 3, an evaporator 12 facing the suction port 8, and a condenser 13 facing the suction port 8' are arranged, and a well-known refrigeration cycle is installed. It consists of 14 is a fan for the evaporator, 16 is a fan for the condenser, and the evaporator 12. It is arranged opposite to the condenser 13 and rotated by a motor 16 at the same time. 17
is a fan casing for the fan 14, which guides air from the suction lower to the cold air outlet 10 via the evaporator 12.

18 is a fan casing for fan 16, and inlet 8
' Air is guided to the hot air outlet 9 via the condenser 13. 19 fixes the evaporator 12 and connects the fan 14
A partition plate 21 forms a fan ring 2o for fixing the condenser 13 and a fan ring 22 for the fan 15.
This is a partition plate with a 23 is a water storage tank for storing dehumidified water from the evaporator 12, and the dehumidified water is guided by a dehumidifying tray 24 arranged below the evaporator 12.

Next, the configurations of the gate-shaped pillars 4 and 5, the partition plates 19 and 21, and the fan casings 17 and 18 will be described in further detail.

The gate-shaped supports 4 and 5 have parallel leg sides 4a.

4b (not shown), sa, sb and this leg side 4a.

4b and a connecting side 4c connecting the tops of sa and sb.

6C, and the bottom plate 3 is symmetrical to each other.
It is located in The partition plate 19.21 is the evaporator 12. Each of the condensers 13 is bent into a U-shape so that it is placed inside the gate-shaped supports 4 and 6, and the partition plates 1
Both sides of 9 are leg sides 4a.

4b, and both sides of the partition plate 21 are fixed to leg sides 5a and sb. Therefore, when the partition plates 19 and 21 are fixed to the gate-shaped supports 4 and 6, they can be moved slightly toward or away from each other as shown by the arrows in the figure. On the other hand, the fan casing 18 for the fan 16 is molded from hard plastic such as polystyrene, and has a boss portion 18a that fixes the motor 16 on the back side and a fitting projection 17a of the fan casing 17 that will be described later. Matching groove 18b
A boss 18C for fixing the fan casing 18 to the partition plate 21 with screws 26 is also formed on the opening side where the partition plate 21g comes into contact. Further, the fan casing 17 for the fan 14 is made of a molded and cut material such as styrofoam, and has an engaging protrusion 17 on the back side that fits into the fitting groove 18b.
a, and the opening side is arranged so as to be in close contact with the partition plate 19. In other words, when assembling, the motor 16 is fixed to the fan casing 18, the fan casing 17 is assembled to the fan casing 18, and the fan 14.15 is fixed to the rotating shaft of the motor 16.The assembly is shown by arrow A in FIG. Side partition plate 19.21 fixed to gate-shaped pillars 4 and 6
the fan casing 18 with screws 2
It is fixed to the partition plate 21 at 6. After that, in order to bring the fan casing 17 into close contact with the partition plate 19, the connecting piece 4
An angle (not shown) is bridged and fixed between c and 5C.

Therefore, since the fan casing 17 has heat insulating properties, it goes without saying that sweating does not occur, and since the fan casing 17 is supported by the fan casing 18, there is no need for separate parts such as a support plate, a mounting plate, and a fixing plate. Further, since the motor 16 is also fixed to the fan casing 18 made of hard plastic, a separate angle for the motor 16 is not required.

As is clear from the above description, according to the present invention, the fan casing made of molded heat insulating material is combined with the fan casing made of hard resin, and both are fixed by fixing the latter fan casing. Does not require support members, etc., reduces weight and prevents sweating,
Since the motor is also fixed to the latter fan casing, there is no need for an angle for the motor, resulting in further weight reduction, and the reduction in the number of parts simplifies assembly and has significant benefits in terms of cost reduction. It is something that can produce.
