Description

Structure of outdoor unit panels for separate type air conditioner.

Background of the invention Field of the Invention

The present invention is about a separate type air conditioner, and more particularly, about a panel structure on the front and back sides of a separate type air conditioner, which can eliminate the Multi-component vibration in an outdoor unit.

Background of the related technique

The separate type air conditioner is provided with a unit inside that has an evaporator to perform heat exchange with indoor air to discharge cold air, and an outdoor unit to perform the heat exchange with external air to discharge hot air. In particular, the outdoor unit is provided with a Compressor, motor, fan, condenser, etc., coated by the front and back panels that make up the appearance External outdoor unit.

When the outdoor unit is set to functioning, there is a vibration that takes place in the components, such as the compressor, the motor, the fan, etc., (components that cause vibration) and that is transmitted to the Compressor, inevitably. If the vibration frequency originated in the components that cause vibration is below a natural frequency of the panel, most of the vibration coming from the components that cause vibration is interrupted due to the rigidity of the panel. However, if the natural frequency of the panel is in the frequency range of the components that originate the vibration, the panel resonates causing a loud noise or warping the panel. To avoid this a variety of procedures, such as providing the panel with a thick plate or similar, to suppress or absorb vibration from components, most procedures already have problems which are accompanied by an increase in the cost of production and a productivity drop. Consequently, as a procedure that costs less but is still productive, a procedure for the application of conformation to the panel to suppress vibration, which is known as a technique in which press a flat panel to lower a part of it by means of a team, such as a press or similar. The conformation makes that the module of the panel section be larger to improve the rigidity, and to increase the natural frequency of the panel. How much more high is the natural frequency of the panel, the harder the panel resonance with the components that cause vibration, what which in the same way improves a vibration suppression effect of the panel.

A panel of related art will be described in an outdoor unit for a type air conditioner separate to which conformation has been applied, making reference to Figs. 1A \ sim 2B. Figs. 1A and 1B illustrate a view in perspective and a front view of a front panel, and Figs. 2A and 2B illustrate a perspective view and a front view of a back panel and a side panel.

Referring to Figs. 1A and 1B, the panel front 10 is provided with curved coupling parts 11 and 12 inwards for coupling with a rear panel 20, of a cover (not shown), from a base (not shown) to along the sides thereof, of an inlet 13 of external air on a side part (left side in Figs. 1A and 1B) of the panel front 10 in front of a part of an air conditioner where a fan is attached (not shown), and a part 14 of coupling in an inner circumference of the air inlet 13 external to adjust a front grille (not shown) to the same. To improve the rigidity of the front panel 10 of the technique related, a first formed part 15 is provided in a part where the other side of the front panel 10 is adjusted (one side right in Figs. 1A and 1B) in front of a part of a compressor. Most of the first part 15 formed into one part located in front of a part where the compressor fits has a vertically elongated rectangular shape, because the Compressor has a vertically elongated shape.

Referring to Figs. 2A and 2B, the panel rear 20 is provided with side panels 30 curved towards forward on opposite sides of the back panel 20, of a part 31 front panel coupling 10 at each end of the panels 30 for coupling with the coupling part of the rear panel 20 of the front panel 10, and a part of 21 or 32 coupling on the lower and upper sides of the panel rear 20 and each of the curved side panels 30 inwards for coupling with the cover or base. There are 50 grids on at least one side of the back panel 20, and in at least one of the two side panels 30. These grilles 40 and 50 serve to force the external air into the indoor outdoor unit through entrance 13 of external air by means of an outdoor unit fan that will be subjected to heat exchange in a condenser (which not shown) and it will be downloaded slowly. Although Fig. 2A illustrates the grid 50 formed in only one side panel 30, there are cases in which the grilles 50 are formed in both panels 30. The back panel of the prior art related and the side panels 20 and 30 have a second shaped part 22 in a part in front of a part in which the condenser and grilles 40 and 50 that are not shaped, is say, on the other side of the back panel 20 (a left side in Figs. 2A and 2B) to improve stiffness. As it has been explained, the part in front of a part where adjust the condenser, that is, the second shaped part 22, It has a vertically elongated rectangular shape that is due to the compressor shape, with a width in Figs. 2A and 2B less than the width of the vertically elongated rectangular shape of the Figs. 1A and 1B. The conformation of the first and second parts formed 15 and 22 in parts of the front and back panels, it is that is, in parts located in front of a part where it fits the compressor increases the module of the section of the panels 10 and 20, to improve the rigidity of panels 10 and 20, which in turn Improves a vibration absorption effect.

However, the application of the first and the second parts conformed to the front and rear panels of the related technique has been performed, not in optimal parts, which can suppress the vibration of the outdoor unit to the fullest, but in appropriate parts that have large suitable areas, it is that is, on the front and rear panels located in front of a part where the compressor is adjusted simply based on the designer intuition. Although the application of the first and second local shaping parts have an increased stiffness of front and back panels compared to a lining in which does not apply the shaped parts, since the parts conformed do not apply to decisive parts for the rigidity of front and rear panels, stiffness is not optimized, that is the natural frequencies of the front and rear panels including the side panels. Therefore, if the vibration from the components that cause vibration of the outdoor unit by applying the first and second shaped parts provided on the front panels and later, the vibration cannot be reduced if it is not using means that involve a high cost and a fall in the productivity.

To the components of this invention identical to those of the related art are They provide the same reference symbols. At the moment invention, the main importance is given to the improvement of stiffness of a panel structure by modifying a part shape formed and by applying a new shaped part.

Referring to Figs. 3A \ sim 4D, the front panel 10 of the present invention has an inlet 13 of air in a side part, and a first part formed 15 in the another side part in front of a compressor, and the rear panel 20 It has a grid on one side and a second part formed 15 on the other side part in front of the compressor. There is side panels 30 on both edges of the rear panel 20 coupled to the front panel 10 with a grid in at least one of side panels 30. Front, back and side panels form a panel structure of a basic outdoor unit for a type air conditioner separate from the present invention.

To reinforce the rigidity of a one-part panel which is the weakest versus vibration according to the analysis of vibration based on the panel structure of an outdoor unit basic free, a third formed part 16 is provided around the air inlet 13, a few quarters are provided shaped parts 41 and 51 in grilles 40 and 50, and provide fifth fifths shaped for some nerves 42 and 52 of grids 40 and 50. In particular, because the parts Top and bottom of the front, back and side panels are weak against vibration, it is favorable that the edges of the first to fourth parts formed 15, 16, 22, 41, and 51, are conform near the edges of the front, back, and lateral, 10, 20 and 30. Taking into account the fact that the panels front, back, and side 10, 20 and 30 are rectangular, it is favorable than the first to the fourth parts formed 15, 16, 22, 41 and 51 are rectangular. The previous panel structure of the Basic outdoor unit of the present invention increases the module of the edge section of the front panels, posterior, and lateral 10, 20 and 30, which improves the suppression of the vibration in the upper and lower parts of the panels.

It is preferable that the fourth parts formed 41 and 51 conform according to grilles 40 and 50 as well as in the near the edges of the adjacent front and side panels, because the fourth parts formed only according to the grilles 40 and 50 do not provide a suitable section module.

It is preferable that the ribs 42 and 52 of the fifths formed 43 and 53 have widths greater than of the other adjacent nerves 44, 45, 55 that are not shaped. However, if the adjacent nerves 44, 45, and 55 not formed have adequate widths sufficient to apply a process of conformation, it is not necessary to define the widths of nerves 42 and 52 to which the fifth part applies conformed 43 and 53 are superior to those of adjacent nerves 44, 45, and 55 not conformed.

Meanwhile, although the fifth parts shaped 43 and 53 are formed according to the vertical ribs 42 and 52 in Figs. 4A \ sim 4D, the conformation of the fifth parts conformed 43 and 53 is not necessarily limited only to nerves vertical 42 and 52, but can be applied only to the nerves horizontal 45 and 55, or all or some of the nerves horizontal and vertical 42, 52; 45, 55, to improve the module the section.

The first to the fifth parts formed 15, 16, 22, 41, 51, 43, 53 may be hollowed out in one direction, or from alternately, or in any direction according to the intention from the designer. In the preferred embodiment of the present invention, the addresses of the incoming first and third parties conformed 15 and 16 are configured to be opposite for Get a good look. In detail, in the front view of the front panel 10, the first shaped part 15 is convex, and the conformed third part is concave, to form a section of a limit of the first and third parts formed 15 and 16 in which Steps will be formed (see Fig. 3D).

Similarly, the fourth and fifth parts shaped 41, 51; 43, 53 also have alternate starters for get a good look for the back and side panels 20 and 30 having the grids 40 and 50 formed therein. In particular, the fourth convex parts formed 41, 51 and the concave shaped fifths 43, 53 provide better visual appearance

Referring to Figs. 4A and 4B, if requires that the rear panel 20 be more rigid, the Second shaped part can be divided into two. In detail, the second shaped part is divided into two rectangular parts 22 and 23, vertically elongated, to provide facing edges of the same which increases the module of the section improving the back panel stiffness 20.

Meanwhile, it is preferable that the distances between the edges of the first to the fourth shaped parts 15, 16, 22, 41, and 51 and the edges of the front, back and lateral 10, 20 and 30 are limited to 5 \ 20 mm taking into it has a conformability from the shaped parts first to fourth 15, 16, 22, 41, and 51. If the distance is less than 5 mm, the edges of the panel are rolled due to the thickness of the panel proper, which deteriorates the formability of the first to the fourth formed parts 15, 16, 22, 41, and 51. If the distance is greater than 20 mm, there is an excessive clearance between the edges of the first to the fourth parts formed 15, 16, 22, 41, and 51, and the edges of the front, back and side panels 10, 20 and 30, in such a way that it will be difficult to expect an increase in the module of the section due to the first to fourth shaped parts 15, 16, 22, 41, and 51. That is, the distance between the shaped parts and the edges 5 \ 20 mm satisfies both the formability and the panel section module. This is applicable at a distance. between the edges of nerves 42 and 52 and the edges of the fifths shaped parts 43 and 53, that is, for there to be a slack of 5 \ 15 mm between the edges of the ribs 42 and 52 and the edges of the fifth formed. It is known thanks to experiments that is preferable that the distance between edges of the shaped parts Be less than the previous distances. That is, it is preferable than the opposite edges of the first and third shaped parts 15 and 16 and the adjacent edges of the second and fourth parts conformed 22 and 41 are limited to 5 ~ 15 mm.

Although distances may vary with sizes and structures of the systems, and with the thicknesses of the panels, the distance can be applied to the air conditioner of separate type manufactured by the applicant and conditioners of market air. Therefore, if necessary, they can find precise distances for each system using the Vibration analysis suggested in the present invention.

Referring to Fig. 5B, a result of the deformation analysis of the back and side panels for natural vibration from first to third order shows that the deformation of the present invention is inferior to that of the art related, understanding that in this way an effect of vibration suppression of the present invention.

As explained, finding a panel position that is the weakest against vibration using vibration analysis, and providing parts conformed to the weak parts, the structure of panels of a outdoor unit for a separate type air conditioner of the present invention can form a panel that has a stiffness maximum That is, the panel with maximum rigidity can increase the natural frequency of the panel, which suppresses the vibration of the panel. Eventually, the panel structure of an outdoor unit free for a separate type air conditioner here invention can suppress vibration with a low cost without this It implies a deterioration of productivity.

It will be evident to those who are experts in the technique that can be performed on the panel structure of a outdoor unit for a separate type air conditioner of the present invention several modifications and variations without get out of the idea or scope of the invention. I mean, I know it is intended that the present invention cover the modifications and variations of this invention provided they enter into the scope of the appended claims and their equivalents.
