Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner, such as a window type air conditioner or a spot cooler, in which a compressor, an evaporator, and a condenser are arranged in one housing.

Generally, such an air conditioner is divided into an indoor side and an outdoor side by providing a partition plate on the bottom plate, and fixes a condenser on the outdoor side and an evaporator on the indoor side.
The fans for the condenser and evaporator were fixed to motors fixed to the partition plates. Therefore, when assembling the fan casing, fan, and motor, it is necessary to assemble them individually and sequentially.
It was difficult to assemble, and the assembly process was inevitably complicated.

Therefore, the present invention combines a lower assembly centered on refrigeration cycle parts and an upper assembly centered on a fan, thereby making it possible to assemble both assemblies in separate processes, thereby improving ease of assembly. This is intended to simplify the assembly process, and one embodiment thereof will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes an air conditioner body 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 columns 4 and 5 erected at the corners of a bottom plate 3 on which casters 2 are provided, and an outer panel 6 and a front panel 7 having a U-shaped cross section are formed on the outer periphery of the columns 4 and 5. It is covered with an outer shell. Outer panel 6
Indoor air intake ports 8 and 8' are provided at positions facing each other, a warm air outlet 9 is provided at a location adjacent to the intake port 8', and a cold air outlet is provided in the front panel 7 adjacent to the intake port 8. A discharge port 10 is provided. Inside the main body 1, a compressor 11 is disposed on the bottom plate 3, an evaporator 12 facing the suction port 8, and a condenser 13 facing the suction port 8' are arranged, forming a well-known refrigeration cycle. are doing. 14 is a fan for the evaporator, 15 is a fan for the condenser, and the evaporator 1
2, the motor 16 is placed opposite the condenser 13;
are rotated at the same time. Reference numeral 17 denotes a fan casing for the fan 14, which guides air from the suction port 8 to the cold air discharge port 10 via the evaporator 12. Reference numeral 18 denotes a fan casing for the fan 15, which guides air from the suction port 8' to the warm air discharge port 9 via the condenser 13. 19
21 is a partition plate that fixes the evaporator 12 and forms a fan ring 20 for the fan 14; 21 is a condenser 13;
This is a partition plate on which a fan ring 22 for a fan 15 is formed. Reference numeral 23 denotes a water storage tank for storing dehumidified water from the evaporator 12, and the dehumidified water is guided by a dew pan 24 arranged below the evaporator 12.

Next, there is a lower assembly A consisting of the above-mentioned portal-shaped supports 4, 5, compressor 11, evaporator 12, condenser 13, partition plates 19, 21, fans 14, 15, motor 16,
The upper assembly B consisting of the fan casings 17 and 18 will be described in further detail. The compressor 11 is attached to the bottom plate 3
It is placed and fixed approximately in the center of the The portal-shaped supports 4, 5 have parallel leg sides 4a, 4b (not shown) and 5a,
5b, leg sides 4a, 4b, and connection sides 4c, 5c that connect the tops of 5a, 5b, and are arranged on the bottom plate 3 so as to be symmetrical with each other. The partition plates 19 and 21 are the evaporator 12 and the condenser 1.
3 is bent into a U-shape so that it is placed inside the gate-shaped pillars 4 and 5, and both ends of the partition plate 19 are fixed to the leg sides 4a and 4b, and the partition plate 21 is fixed to the leg sides 4a and 4b. Both sides are fixed to leg sides 5a and 5b. Therefore, each partition plate 1 is attached to these gate-shaped supports 4 and 5.
When 9 and 21 are fixed, they can be moved slightly closer to or further away from each other as shown by the arrows in the figure.

This assembly A includes a compressor 11 and an evaporator 1.
2. The assembly of the condenser 13 is completed by connecting the refrigerant pipes in advance.

On the other hand, in the upper assembly B, a fan casing 18 for the fan 15 is molded from hard plastic, and a boss portion 18a that fixes the motor 16 on the back side fits into an engaging protrusion 17a of the fan casing 17, which will be described later. forming a fitting groove 18b that allows
A boss 18c for fixing the fan casing 18 to the partition plate 21 with screws 25 is formed on the opening side that contacts the partition plate 21. Also Juan 14
The fan casing 17 is made of a molded heat insulating material such as styrofoam, and has a fitting groove 18b on the back side.
An engaging protrusion 17a that fits into the opening side is formed so as to be in close contact with the partition plate 19. That is, when assembling, the motor 16 is fixed to the fan casing 18, the fan casing 7 is assembled to the fan casing 18, and the fans 14 and 15 are further fixed to the rotating shaft of the motor 16 to form the assembly B.
This assembly B is inserted into the space between the partition plates 19 and 21 fixed to the gate-shaped supports 4 and 5 as shown by the arrow C in FIG. It is to be fixed at Thereafter, in order to bring the fan casing 17 into close contact with the partition plate 19, an angle (not shown) is bridged and fixed between the connecting pieces 4c and 5c.

As described above, according to the present invention, between the opposing partition plates of the lower assembly centering on the refrigeration cycle components,
In addition to fixing the motor to either one, the upper assembly centering on the mutually joined fan is inserted and fixed, so compared to the case where each part is sequentially attached and fixed to one board, both assemblies can be mounted in parallel. Since the parts can be assembled together, the assembly process is simplified and the ease of assembly is improved. Furthermore, since the upper assembly is inserted between the partition plates, the partition plates are generally flat without any complicated machining, so that they can be arranged smoothly and easily.
