Description

[Detailed Description of the Invention] [Eleventh Field of the Invention] The present invention relates to a housing vibration prevention structure of an outdoor unit in a JD package air conditioner, and is particularly suitable for use in an outdoor unit of a separate air-cooled package air conditioner. Regarding the housing vibration prevention structure.

[Prior art]

Fig. 1 is an external perspective view showing an external unit of a separate cold package air conditioner, and Fig. 2 is an external perspective view of an outdoor unit with a conventional housing vibration prevention structure, with a safety net for the air outlet opening. Shown is the removed state. In the figure,
1 is a base, and 2 is a box-shaped housing installed on the base 1, and has an upper cover 2A on the top surface and a service cover 2B on the left side. Inside this housing 2,
A blower 5 consisting of a motor 3 and a propeller fan 4 and a compressor 6 are housed, and an external heat exchanger (not shown) is housed in the base 1 on the back side of the housing 2 (air suction side of the outside unit). ) is installed. Also, housing 2
On the front side (air blowing side of the outdoor unit), there is provided an air blower opening lower to which a safety protection net 8 is attached. The blower 5 is attached to the housing 2 at the air blower opening lower portion by connecting the support arm 9 provided on the motor frame of the motor 3 to the housing 2. The compressor 6 is fixedly mounted on the base 1, and its suction pipe 10 and discharge pipe 11 protrude from the Zerpis force bar 2B of the housing 2. In the outdoor unit, the propeller fan 4 is driven by the motor 3. When it rotates, the 40 rotational vibration of the propeller shaft 1 is transmitted to the housing 2 via the support arm 9 of the motor 3, causing the housing 2 to vibrate. Since this vibration causes noise in the outdoor unit, it is necessary to prevent it.

However, in the conventional case vibration prevention TJ construction, as shown in FIG. By fixing the reinforcing phase 13 in the horizontal direction by spot welding, the housing 2
This is to prevent vibration.

However, if the housing 2 shakes 1lllllI, the vibration in the vertical direction,
It is a complex vibration such as left and right shooting, front and back vibration, and the front and back vibration is the largest, so the conventional housing vibration prevention structure mentioned above can prevent vertical and left and right vibrations, but It was not very effective against vibrations, and it was difficult to reduce the noise of the outdoor unit.

[Purpose of the invention]

An object of the present invention is to provide a housing vibration prevention structure that can prevent vibration of the housing of an outdoor unit and reduce noise.

[Summary of the invention]

In order to achieve this objective, the outdoor unit casing vibration prevention structure of the packaged air conditioner of the present invention has a casing of the same shape installed on the base, and a blower consisting of a compressor, a motor, and a propeller fan inside the casing. At the same time, an outdoor heat exchanger is attached to the base on the back side of the casing, an air blowing opening is provided in the front of the casing, and the blower is connected to the motor frame at the air blowing opening. In an outdoor unit in a package air conditioner, the compressor is attached to a housing via a support arm provided on a base, and a plurality of reinforcing members are provided in front of the housing, centered at the center of the air blowing opening. It is characterized by being arranged in the radial direction and provided integrally with the housing.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIG. Third
The figure shows the vibration prevention (structure) of the casing of the present invention ji6. FIG. 2 shows a perspective view of the external appearance of the 9F unit in the separate air-cooled package air conditioner. In the figure, the same reference numerals as those in FIG. 1 indicate the same or different parts, so the explanation thereof will be omitted. The housing vibration prevention structure of the present invention includes a plurality of angle-shaped reinforcing members 14 fixed by spot welding on the inside front of the housing 2,
In addition, the reinforcing members 14 are arranged in a radial direction centered on the center of the lower air blowing direction.

However, in the case vibration prevention structure of the present invention, the case 2
However, it is reinforced by a plurality of reinforcing members 14 arranged in the radial direction around the center of the air blowing mountain opening lower, and its rigidity is increased, so that the vibration of the housing 2, that is, the largest front-back direction imaging This also prevents vertical and horizontal vibrations. As a result, the noise of the outside unit is significantly reduced.

Similarly, in the above embodiment, an example was shown in which each reinforcing material 14 was fixed to the casing 2 by all spot welding. may be formed.

〔Effect of the invention〕

As explained above, the housing vibration prevention structure of the present invention can prevent vibration of the housing by reinforcing the housing with a plurality of reinforcing materials arranged in a radial direction around the center of the air outlet opening. Can reduce noise from outside unit.
