detailed description

In order to solve the problems in the prior art, such as the resonance and noise problems of the grid on the outdoor unit of the air conditioner, the first aspect of the invention provides a grid.

As shown in FIGS. 1-7, the grille of the present invention is provided with a raised structure 2 capable of abutting against a structure for mounting the grille when the grille is in a mounted state. (for example, the mask of the air conditioner outdoor unit). Generally, the grille can be regarded as a two-dimensional member, and has inner and outer sides in a mounted state. For example, when mounted on an outdoor unit of an air conditioner, the inner side is a side facing the air conditioner outdoor unit, and the outer side is a side facing away from the air conditioner outdoor unit. . The protruding structure 2 may protrude, for example, toward the inner side in the state in which the grid is mounted, or may protrude toward each of the radial directions of the side (for example, a spherical body or a columnar body that is sleeved on the side). .

The raised structure 2 provides support between the grid and the structural member for mounting the grid, since the raised structure 2 itself has a certain height (for example, preferably 2 to 3 mm), making the other parts of the grid difficult Contact with the mask (except for the fastening points of the grille), so that even in the case of deformation of the grille, resonance can be well avoided and the noise during startup of the unit can be reduced.

Preferably, the grille of the present invention may include a bezel 1 and a mesh fixedly coupled to the inside of the bezel 1 , wherein the raised structure 2 may be disposed on at least one side of the bezel 1 or may be disposed at The beams that make up the grid. In the case of a frame 1, the mesh may comprise only beams in one direction, such as simple beams or stringers, but may also include intersecting beams, such as staggered beams and stringers.

Alternatively, the grid of the present invention may also include no borders, but only grids, in which case the raised structures 2 are disposed on the beams that make up the grid. To form a unit when the grid does not include a frame, the grid includes intersecting beams, such as staggered beams and stringers.

Preferably, in the case where the grille comprises the bezel 1, the raised structures 2 are arranged in pairs on opposite sides of the bezel 1. For example, a pair of raised structures 2 can be provided, respectively disposed on the sides The two vertical or lateral sides of the frame 1 are such that there are no more contact points on the respective two sides than the raised structure 2. Alternatively, two pairs of raised mechanisms 2 may be provided, which are respectively disposed on the four sides of the bezel 1 so that there are no other contact points on each side except the raised structure 2.

Preferably, the grid is a metal welded grid. Since the convex structure 2 is provided, when a metal welding grid (for example, a metal dip grill) is used, even if the grille frame 1 is slightly deformed due to a large number of solder joints, the frame and the mask can be effectively ensured. Multi-point contact or false contact is formed, thereby effectively avoiding resonance and reducing noise.

Preferably, the raised structure 2 may be formed by bending deformation of a material constituting the grating (for example, a side of a frame and/or a beam of a mesh), for example, as shown in FIG. 5, as may be welded in a grid. After completion, the stamping deformation is performed at the corresponding position on the side to constitute the raised structure 2.

Alternatively, the raised structure 2 may also be a convex hull welded on the material constituting the grating (for example, the side of the frame and/or the beam of the mesh), for example as shown in FIG. 2, as may be After the grid welding is completed, a convex hull is welded at a corresponding position on the side, so that the protruding direction includes the inner side when facing the grid mounting state.

Preferably, as shown in FIG. 1 and FIG. 3, the grid comprises a frame 1 and a grid fixedly connected to the frame 1 , the grid comprising a first beam and a second beam 3 disposed crosswise, wherein The internal spacing of the first beam (i.e., the spacing between adjacent two first beams) is different from the internal spacing of the second beam (i.e., the spacing between adjacent two second beams). For example, as shown in FIG. 3, the internal spacing of the first beam (for example, a beam) is small, and the internal spacing of the second beam (for example, a longitudinal beam) is large, thereby forming a long grid, and the first beam is more dense; Also.

Preferably, the raised structure 2 is disposed on the side of the border 1 where the intersection is dense, wherein the intersection refers to the intersection of the side of the frame with the first beam or the second beam, and the side of the intersection is dense Refers to the side edges of the frame that intersect one of the first and second beams. For example, in the embodiment shown in FIG. 3, since the first beam (beam) is denser, the intersection of the first beam and the two vertical sides is denser, and these intersections are simultaneously welded during welding. Therefore, the two vertical sides are more susceptible to micro-deformation due to the large number of solder joints. For this reason, the raised structure 2 is preferably disposed on two vertical sides, thereby effectively reducing the vertical side contact with the mask. Point or false contact points to reduce noise. It is envisaged that the grid of the present invention may also be arranged such that the second beam (longitudinal beam) is more dense so that the raised structure 2 is preferably disposed on a lateral side that intersects the second beam.

The grille of the present invention, by means of the above-described arrangement of the raised structure 2, enables the raised structure 2 to firmly hold the mask after assembly, effectively avoiding the resonance and noise problems of the grid.

In addition, since the grille is disposed at the air outlet at the time of operation, for example, the fan of the outdoor unit of the air conditioner needs to withstand a large wind force, the present invention has found that the steel wire constituting the metal grille (the frame, the The first beam and the second beam are preferably composed of steel wires. The diameter has a certain relationship with the air volume. The larger the wire diameter, the smaller the air volume, and the greater the grid strength.

Therefore, in order to optimize the strength and the air volume of the metal grid at the same time, the present invention designs the wire arrangement of the grid. Preferably, the first beam and the second beam have different diameters, for example, The diameter of the beam with a large internal spacing is also large.

Preferably, in one of the first of the first beam and the second beam, the diameter of at least a portion of the beam is different from the diameter of the beam of the other portion. In the embodiment shown in FIG. 3, the internal spacing of the first beam (beam) is small, so that at least a portion of the diameter of the first beam (beam) is different from the diameter of the other portion of the first beam (beam), thereby ensuring Under the premise of strength, try to maximize the air volume.

Preferably, in one of the first of the first beam and the second beam, the diameter of a portion of the beam at least near the side of the frame decreases in a direction from the side to the inside. For example, in the embodiment shown in FIG. 3, the internal spacing of the first beam (beam) is small, and therefore, among the first beams, at least a portion of the first beam having a diameter close to the upper and lower sides is from the upper and lower sides to The internal direction is decreasing. Taking the first beam (beam) near the lower side as an example, the diameters of the first beam 10 and the second beam 9 are the largest, for example, 3 mm, and the diameters of the third beam 4 and the fourth beam 7 are reduced, for example, It is 2mm, thus showing a decreasing trend in the direction from the edge to the inside. In the case where the strength of the grid is ensured, a smaller diameter can be selected for each of the beams away from the side. For example, the diameters of the fifth beam 6, the sixth beam 5, and the seventh beam 4 can be maintained at 2 mm.

Preferably, the diameter of the bezel 1 is the same as the diameter of the beam of one of the first and second beams, and is larger than the diameter of the beam of the smaller one. In the illustrated embodiment, the internal spacing of the second beam (longitudinal beam) is large, and the internal spacing of the first beam (beam) is small, and therefore, the diameter of the frame 1 is the same as the diameter of the second beam, for example, 4 mm, and Greater than the diameter of each first beam.

Preferably, the raised structure 2 may be disposed at a corresponding side or an intermediate point of the beam, for example, as shown in FIGS. 1 and 4, at an intermediate point between the left and right vertical sides, thereby Grid When the grid is assembled to, for example, an air conditioner outdoor unit, the gap on both sides of the boss structure 2 can be relatively balanced.

Alternatively, the raised structure 2 can also be arranged at two fastening points 11 (for example by screws) close to the respective side or beam (ie the side or beam on which the raised structure 2 is arranged) The fastening points 11 are fastening points for fixedly mounting the grille at equal distances. For example, as shown in FIG. 3, the grille may include, for example, four fastening points, for example, at four corners, respectively, so that the position of the raised structure 2 can also be based on a fastening point, for example, the left side. The raised structure 2 on the side may be disposed at an intermediate position of the two fastening points 11 near the left side, that is, the distance from the two fastening points 11 near the left side is equal.

Compared with the prior art using a metal grid composed of steel wires of the same diameter, the grid of the present invention can ensure an increase in air volume and grid strength, and contribute to extending the service life of the grid.

The position of the raised structure 2 can also be flexibly set as needed in specific use. Also, the diameter of the wire constituting the grid can be flexibly selected as needed.

Preferably, the grille of the present invention is an outlet grille of an outdoor unit of an air conditioner.

A second aspect of the present invention also provides an outdoor unit for an air conditioner comprising the grille of the foregoing invention, wherein the grille is mounted at an air outlet, and the raised structure abuts against a mask of the outdoor unit of the air conditioner . When the air conditioner outdoor unit is turned on, the fan operates, the airflow is disturbed, and the force acting on the grille is also large. However, since the grille frame of the present invention is provided with the convex structure 2, the raised structure 2 is firmly held against it. The mask of the air conditioner outdoor unit makes the grille unable to resonate, so that no noise is generated.

It will be readily understood by those skilled in the art that the above various preferred embodiments can be freely combined and superimposed without conflict.

The above-described embodiments are to be considered as illustrative and not restrictive. Modifications or substitutions are intended to be included within the scope of the appended claims.
