Detailed Description

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

As shown in fig. 1 to 7, the grille of the present invention is provided with a protrusion structure 2, and when the grille is in an installation state, the protrusion structure 2 can abut against a structural member (for example, a face cover of an outdoor unit of an air conditioner) for installing the grille. Generally, the louver may be considered as a two-dimensional member having inner and outer sides in an installed state, for example, when installed on an outdoor unit, the inner side is a side facing the outdoor unit, and the outer side is a side facing away from the outdoor unit. The projecting structure 2 may for example project in an inner direction when the grating is mounted, or in all radial directions towards the side (for example, it may be a ball or a column that fits over the side).

The raised structure 2 provides support between the grille and the structural member for mounting the grille, and since the raised structure 2 has a certain height (for example, preferably 2-3 mm), other parts of the grille are difficult to contact with the mask (except for fastening points of the grille), so that even if the grille is deformed, resonance can be well avoided, and noise generated when the unit is started up is reduced.

Preferably, the grid of the present invention may include a frame 1 and a grid fixedly connected to the inside of the frame 1, wherein the protrusion structures 2 may be provided on at least one side edge of the frame 1, or may be provided on the beams constituting the grid. In the case of the frame 1, the grid may comprise only one direction of beams, such as simple beams or stringers, or may comprise crosswise arranged beams, such as alternating beams and stringers.

Alternatively, the grid according to the invention may also comprise no borders, but only a grid, in which case the raised structures 2 are provided on the beams constituting said grid. When the grid does not include a perimeter frame, the grid includes intersecting beams, such as alternating cross beams and longitudinal beams, in order to form a unitary body.

Preferably, in the case of a grid comprising a frame 1, said raised structures 2 are arranged in pairs on opposite sides of said frame 1. For example, a pair of protruding structures 2 may be provided, respectively on two vertical or lateral sides of the frame 1, so that there are no other contact points on the respective two sides except for the protruding structures 2. Alternatively, two pairs of protruding mechanisms 2 may be provided, which are respectively disposed on four sides of the frame 1, so that there are no other contact points on each side except the protruding mechanisms 2.

Preferably, the grid is a metal welded grid. Due to the arrangement of the protruding structure 2, when a metal welding grid (for example, a metal plastic-dipped grid) is adopted, even if the grid frame 1 generates micro deformation due to more welding points, multipoint contact or false contact between the frame and the mask can be effectively avoided, so that resonance is effectively avoided, and noise is reduced.

Preferably, the raised structures 2 may be formed by bending and deforming the material forming the grid (e.g. the sides of the frame and/or the beams of the grid), for example as shown in fig. 5, such as by stamping and deforming the grid at corresponding locations on the sides after welding to form the raised structures 2.

Alternatively, the protruding structure 2 may be a convex hull welded to the material forming the grid (e.g. the side edges of the frame and/or the beams of the grid), for example, as shown in fig. 2, it is sufficient to weld a convex hull at the corresponding position of the side edges after the welding of the grid, so that the protruding direction includes the inner side of the grid in the installed state.

Preferably, as shown in fig. 1 and 3, the grid comprises a frame 1 and a grid fixedly connected in the frame 1, wherein the grid comprises first beams and second beams 3 arranged in a crossed manner, wherein the inner spacing of the first beams (i.e. the spacing between two adjacent first beams) is different from the inner spacing of the second beams (i.e. the spacing between two adjacent second beams). For example, as shown in fig. 3, the inner space of the first beam (for example, a cross beam) is small, and the inner space of the second beam (for example, a longitudinal beam) is large, so that an elongated grid is formed, and the first beam is more compact; and vice versa.

Preferably, the protruding structures 2 are disposed on the side edges of the frame 1 with dense intersection points, where an intersection point refers to an intersection point of the side edge of the frame and the first beam or the second beam, and the side edge with dense intersection point refers to the side edge of the frame that intersects with one of the first beam and the second beam with a small inner space. For example, in the embodiment shown in fig. 3, since the first beam (cross beam) is more dense, the intersection points of the first beam and the two vertical sides are more dense, and the intersection points are both welding points during welding, so that the two vertical sides are more prone to micro-deformation due to more welding points, and for this reason, the protruding structures 2 are preferably arranged on the two vertical sides, so as to effectively reduce the contact point or false contact point between the vertical sides and the mask, and reduce noise. It is conceivable that the grid according to the invention can also be arranged so that the second beams (stringers) are more dense, whereby the projecting structures 2 are preferably arranged on the lateral side intersecting the second beams.

According to the grid, the convex structures 2 are arranged, so that the convex structures 2 firmly support the mask after assembly, and the problems of resonance and noise of the grid are effectively solved.

In addition, because the grille is arranged at the air outlet during operation, for example, the grille is directly opposite to a fan of an outdoor unit of an air conditioner and needs to bear larger wind power, the invention discovers that the diameter of the steel wire (the frame, the first beam and the second beam are preferably all made of steel wires) forming the metal grille has a certain relation with the air volume, the larger the diameter of the steel wire is, the smaller the air volume is, and the stronger the grille is.

Therefore, in order to optimize the strength and the air volume of the metal grid at the same time, the present invention designs the arrangement of the steel wires of the grid, and preferably, the first beam and the second beam have different diameters, for example, the beam with a large inner distance has a large diameter.

Preferably, in one of the first and second beams in which the inner pitch is small, the diameter of at least a part of the beams is different from the diameter of the other part of the beams. In the embodiment shown in fig. 3, the inner pitch of the first beams (cross beams) is small, and therefore, the diameter of at least a part of the first beams (cross beams) is different from the diameter of another part of the first beams (cross beams), thereby maximizing the air volume as much as possible while ensuring the strength.

Preferably, in one of the first and second beams in which the inner pitch is small, at least a portion of the beams near the side edge of the bezel have a tendency to decrease in diameter in a direction from the side edge to the inner portion. For example, in the embodiment shown in fig. 3, the inner pitch of the first beams (cross beams) is small, and therefore, the diameter of at least a part of the first beams near the upper and lower sides among the first beams tends to decrease in the direction from the upper and lower sides to the inner portion. Taking the first beam (cross beam) near the lower side as an example, the diameter of the first cross beam 10 and the second cross beam 9 is the largest, for example 3mm, and the diameter of the third cross beam 8 and the fourth cross beam 7 is reduced, for example 2 mm, so that a decreasing trend is shown in the direction from the edge to the inside. Under the condition that the strength of the grating is guaranteed, the diameter of each beam far away from the side edge can be selected to be smaller, for example, the diameters of the fifth beam 6, the sixth beam 5 and the seventh beam 4 can be kept to be 2 mm.

Preferably, the diameter of the bezel 1 is the same as that of the one of the first and second beams whose inner pitch is large, and is larger than that of the one whose inner pitch is small. In the illustrated embodiment, the inner spacing of the second beams (longitudinal beams) is large and the inner spacing of the first beams (transverse beams) is small, so that the diameter of the edge frame 1 is the same as the diameter of the second beams, for example 4 mm, and is larger than the diameter of the respective first beams.

Preferably, the projection structure 2 may be provided at a middle point of the corresponding side or beam, for example, as shown in fig. 1 and 4, at a middle point of both right and left vertical sides, so that a gap between both sides of the projection structure 2 can be maintained more uniformly when the grill is assembled to, for example, an outdoor unit of an air conditioner.

Alternatively, the raised structures 2 may also be arranged at equal distances from two fastening points 11 (for example fastened by screws) close to the respective side or beam (i.e. the side or beam on which the raised structures 2 are arranged), the fastening points 11 being fastening points for the fixed mounting of the grid. For example, as shown in fig. 3, the grid may for example comprise four fastening points, for example at four corners, respectively, and thus the location of the raised structures 2 may also be based on the fastening points, for example, the raised structures 2 on the left side may be located at a position intermediate two fastening points 11 near the left side, i.e. at equal distances from two fastening points 11 near the left side.

Compared with the metal grating formed by steel wires with the same diameter in the prior art, the grating provided by the invention can ensure that the air quantity and the grating strength are increased to some extent, and is beneficial to prolonging the service life of the grating.

The position of the protruding structure 2 can also be flexibly set as required in specific use. Likewise, the diameter of the steel wires making up the grid can also be flexibly selected as desired.

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

The invention also provides an air conditioner outdoor unit, which comprises the grille, wherein the grille is arranged at the air outlet, and the convex structure abuts against a face mask of the air conditioner outdoor unit. When the outdoor unit of the air conditioner is started, the fan runs, airflow disturbance is large, and force acting on the grille is also large, however, because the protruding structure 2 is arranged on the grille frame, the protruding structure 2 is utilized to firmly support the face cover of the outdoor unit of the air conditioner, the grille cannot generate resonance, and noise cannot be generated.

Those skilled in the art will readily appreciate that the above-described preferred embodiments may be freely combined, superimposed, without conflict.

It will be understood that the embodiments described above are illustrative only and not restrictive, and that various obvious and equivalent modifications and substitutions for details described herein may be made by those skilled in the art without departing from the basic principles of the invention.
