Abstract

PURPOSE:To prevent occurrence of an electrical fault due to dropping of water by providing an intermediate partition plate partitioning a blower chamber off a cycle chamber located below it, by providing a fitting member on the partitioning surface of the intermediate partition plate and also by fixing a motor base of a blower to the fitting member. CONSTITUTION:By adopting a construction wherein a motor base 11 and a bellmouth 12 are not fitted directly to an intermediate partition plate 3, water such as rainwater or drain water entering from an opening of a back cabinet 22 or a front panel 7 is checked from dropping down into a cycle chamber 2 through a screw hole 17 or a positioning hole 23, even when it is collected on the partitioning surface 4 of the intermediate partition plate 3 or on fitting plates 5 and 6, and thus it can be prevented from wetting an electric wire or a terminal and causing an electrical fault. In other words, a vertical type outdoor unit structure having high safety and reliability is attained. Since the motor base 11 and the bellmouth 12 are fixed and supported by screws 20 and the like, they can be disjoined easily as occasion demands and this is convenient for maintenance or recycling.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outdoor unit for an air conditioner.

[0002]

2. Description of the Related Art Generally, an outdoor unit of an air conditioner is
Blower, motor, heat exchanger are stored in the bottom plate,
A compressor and an electric parts box are arranged side by side through a partition plate. And this whole is covered by the cabinet. However, in the outdoor unit having such a structure, since the respective parts are arranged side by side, the outdoor unit is widened laterally, and the installation place is limited. For this reason, the outdoor unit is made vertical and the compressor, the blower, the heat exchanger, and the electric parts are sequentially arranged from the lower part to save space in the lateral direction.

[0003]

By the way, in the vertical outdoor unit, the cycle chamber including the compressor and the blower chamber including the blower above it are partitioned by the middle partition plate, and the motor base of the blower is directly connected to the middle partition plate. It is designed to be screwed on. For this reason, there was a problem that drain water and rainwater leaked from the screw part and the positioning hole for positioning and dripped into the cycle chamber, wetting the compressor terminal, electric parts and lead wires, causing short circuit, corrosion, etc. .

Therefore, the present invention was devised to provide a vertical outdoor unit of an air conditioner in which no electrical trouble due to the dropping of moisture occurs.

[0005]

SUMMARY OF THE INVENTION The present invention provides a partition plate for partitioning a blower chamber and a cycle chamber therebelow, a mounting member on the partition surface of the partition plate, and a motor for a blower on the mounting member. It has a fixed base. Further, in the present invention, instead of the above-mentioned mounting member, a mounting step portion higher than the surroundings is integrally formed on the partition surface, and the motor base of the blower is fixed to the mounting step portion.

[0006]

With the above structure, drain water and rainwater that have adhered to the intermediate partition plate via the blower chamber and the like are treated on the partition surface even if they pass through the threaded portions and the positioning holes of the mounting member, and drip into the cycle chamber. Never. Further, due to the structure in which the mounting step portion is formed, drain water and rainwater collected in the threaded portion of the mounting member are drained to the surrounding low partition surface.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 and 2 show an embodiment of a vertical outdoor unit of an air conditioner according to the present invention.
The vertical outdoor unit is provided with an intermediate partition plate 3 for partitioning the blower chamber 1 and the cycle chamber 2 therebelow.
Two partition plates 5 and 6 as mounting members are provided on the partition surface 4 of the middle partition plate 3.

The blower chamber 1 has an outlet grill 7 and a front panel 8.
And a propeller fan 9 directed to the outlet grill 7, a fan motor 10 for rotating the propeller fan 9, a motor base 11 for supporting the fan motor 10, and a propeller fan 9 are appropriately enclosed. Bell mouth 12 and is provided. An electric component box 13 accommodating an inverter and the like and a heat exchanger 14 are arranged on the upper portion or the side portion of the blower chamber 1. In addition, electrical parts box 1
A waterproof cover 13a is attached to the opening portion of 3. A compressor 15 is housed in the cycle chamber 2 and is fixed on a bottom plate 16. The middle partition plate 3 is erected on the back side of the bottom plate 16 and is bent substantially horizontally at a position slightly above the head of the compressor 15, or another plate is integrally attached. That is, this horizontal face plate is formed as the partition surface 4.

As shown in FIG. 1, a part of the partition surface 4 of the middle partition plate 3 is slightly bulged upward, and a rectangular first mounting plate 5 is superposed on this part for spot welding. It is fixed. Then, a smaller rectangular second mounting plate 6 is provided on the first mounting plate 5, both sides of which are folded back and spot-welded at this portion. A screw hole 17 and a positioning hole 23 are formed in the second mounting plate 6, and are arranged so as to correspond to the screw hole 19 and the positioning piece 24 formed in the flange portion 18 of the motor base 11, respectively.

That is, the motor base 11 is positioned on the second mounting plate 6 by the positioning holes 23 and the positioning pieces 24, and is fixed by the screws 20. The first mounting plate 5 is configured so that the bell mouth 12 is appropriately screwed from the front.

In addition to this, the ventilation unit 1 is included in this outdoor unit.
There is provided a top plate 21 that partitions and covers the upper part of the, and a back cabinet 22 that partitions the back surface and both side surfaces of the blower chamber 1 and the cycle chamber 2.

As described above, since the motor base 11 and the bell mouth 12 are not directly attached to the partition plate 3, the water content such as rain water and drain water that has entered from the openings of the back cabinet 22 and the front panel 7. However, even if it accumulates on the partition surface 4 of the middle partition plate 3 or the mounting plates 5 and 6, the screw holes 1
7 does not drip into the cycle chamber 2 from the positioning hole 23, and it is possible to prevent electric wires and terminals from getting wet and causing an electrical failure. That is, the vertical outdoor unit structure having high safety and reliability is achieved.

Further, the motor base 11 and the bell mouth 12
Since it is fixedly supported by the screw 20 or the like, it can be easily disassembled as required, and it is convenient for maintenance or recycling.

Although the mounting member is composed of two mounting plates in this embodiment, it may be composed of one mounting plate.

FIG. 3 shows another embodiment of the present invention, in which the partition surface 32 of the middle partition plate 31 is deeply squeezed vertically to integrally attach two mounting step portions 33, 34 higher than the surroundings. Is formed in the same way. That is, a screw hole 35 and a positioning hole 36 are formed in the mounting step portions 33 and 34, respectively, so that a motor base (not shown) can be screwed. With this configuration, it is possible to use the low surface portion 37 as a drainage groove to guide the water accumulated on the partition surface 32 to the front or side and prevent the water from dripping in the lower cycle chamber 2. it can. The other constructions and effects are similar to those of the above-mentioned embodiment.

[0017]

In summary, according to the present invention, rainwater, drain water, etc. adhering to the intermediate partition plate do not drip into the cycle chamber, and an excellent effect of preventing electrical trouble is exhibited.
