Detailed Description

In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

Thus, reference throughout this specification to one feature will be used in order to describe one embodiment of the invention, not to imply that each embodiment of the invention must be in the proper motion. Furthermore, it should be noted that the present specification describes a number of features. Although certain features may be combined together to illustrate a possible system design, such features may be used in other combinations not explicitly described. Thus, unless otherwise indicated, the illustrated combinations are not intended to be limiting.

The principles and structures of the present invention are described in detail below with reference to the drawings and the examples.

The panel assembly, as shown in fig. 1 and 2, comprises a panel 1 installed on an air conditioner external unit, a baffle 2 detachably installed on the panel 1, a first through hole 11 arranged on the panel 1, and a second through hole 21 arranged on the baffle 2;

the second through hole 21 falls in the scope of first through hole 11 after baffle 2 and panel 1 are installed, and the aperture of second through hole 21 sets up according to the line demand of crossing of the outer machine of air conditioner, and the aperture of first through hole 11 is greater than the aperture of second through hole 21.

Specifically, as shown in fig. 3, the panel assembly is installed at the bottom edge of the air conditioner external unit, and functions as a mounting sleeve for providing a passage for the strong electric wires 32 and the weak electric wires 31. The baffle plate 2 is arranged on one side of the panel 1 facing the air conditioner, and the baffle plate 2 is arranged in the air conditioner after the panel assembly is arranged. The panel 1 is provided with a first through hole 11, the plane of the baffle 2 provided with a second through hole 21 is overlapped with the inner side surface of the panel 1, and the second through hole 21 is in the range of the first through hole 11 after installation.

Regarding the positional relationship between the first through hole 11 and the second through hole 21, the preferred embodiment is that the first through hole 11 and the second through hole 21 are coaxial in structure, so that the strong electric wire 32 and the weak electric wire 31 can be conveniently connected on the one hand, and on the other hand, the appearance is more attractive. However, errors are allowed in actual production, as long as the second through holes fall within the range of the first through holes, but since the second through holes 21 are arranged on the baffle plate 2, the baffle plate is arranged on the inner side of the unit, and at least the second through holes 21 are required to be completely exposed from the outer side of the unit, and the second through holes 21 cannot be shielded by the panel 1.

The first through hole 11 on the panel 1 is always larger than the second through hole 21 on the baffle 2, and since the panel 1 is a mold piece, the baffle 2 can be installed to adjust when smaller via hole diameter is needed, and the panel 1 does not need to be re-opened due to different requirements of via hole sizes, so that the development period of the air conditioner is shortened, and the cost of repeated mold opening of the panel 1 is reduced.

Further, when the panel 1 and the baffle 2 are fixed by welding, the panel assembly further includes a convex hull 13 provided on the panel 1, and a positioning through hole 25 provided on the baffle 2 and matched with the convex hull 13.

Specifically, as shown in fig. 2, the panel 1 and the baffle 2 may be fixed by welding, and a convex hull 13 is provided at the edge of the first through hole 11 of the panel 1, if only one convex hull 13 is provided, the baffle 2 may still slide after being positioned by the one convex hull 13, which may result in that the second through hole 21 on the baffle 2 and the first through hole 11 on the panel 1 are not located at the same position, and at least two convex hulls 13 used for positioning need to be provided at one side where the panel 1 and the baffle 2 contact, so that displacement cannot be generated after the baffle 2 is fixed to the panel 1. When the baffle plate 2 is required to be mounted on the panel 1, the positioning through holes 25 formed in the baffle plate 2 are positioned by the convex hulls 13 on the panel 1, and then spot welding is performed to weld the baffle plate 2 to the panel 1. The baffle plate 2 can be guaranteed to be mounted at a preset position by arranging the convex hulls 13, the baffle plate 2 does not need to be visually positioned during actual welding operation, and the baffle plate 2 can be directly welded after being unable to move any more when the baffle plate 2 is pressed to the two convex hulls 13 on the panel 1 during operation, so that the working efficiency is improved.

Further, when the panel 1 and the baffle 2 are fixed by screws, the panel assembly further includes a third through hole 14 provided on the panel 1, and a screw hole 26 provided on the baffle 2 and matched with the third through hole 14.

In a specific embodiment, as shown in fig. 4, the panel 1 and the baffle 2 can also be connected by fastening with screws, a third through hole 14 is provided at the edge of the first through hole 11 of the panel 1, at least two third through holes 14 for passing screws are provided on the panel 1, and when the baffle 2 is fastened with the panel 1 by the screws, threaded holes 26 matching the positions of the third through holes 14 are provided on the baffle 2. When the baffle plate is installed, the threaded holes 26 on the baffle plate 2 and the third through holes 14 on the baffle plate 1 are aligned, screws enter through the third through holes 14, the panel plate 1 and the baffle plate 2 are fixed by rotating the accessed threaded holes 26, and after the screws are fastened, the second through holes 21 of the baffle plate 2 can be completely exposed through the first through holes 11 of the panel plate 1.

Further, the first through hole 11 is provided in plurality and includes at least one weak current hole for passing the weak electric wire 31 therethrough and at least one strong current hole for passing the strong electric wire 32 therethrough.

Specifically, the first through holes 11 on the panel 1 are at least three types, one type is a square hole, the square hole is an engineering hole for the engineering pipe to pass through, the engineering hole is also designed in a knock-out structure, and the other type is two types of circular holes, wherein the smaller circular hole is a weak current hole for the weak current wire 31 to pass through, the other circular hole is a strong current hole for the strong current wire 32 to pass through, and the sizes of the holes are set according to the refrigerating capacity of the air conditioner and take the maximum value.

For the sake of easy understanding, the number of air conditioner models in this section is large, and the size of the wire hole diameter varies according to the sales area.

For example, the hole diameter of the wire passing hole required in the north american region is smaller than that required in the non-north american region, because the panel 1 is a mold piece, the mold opening cost and the time cost are relatively large, when the first through hole 11 hole diameter arranged on the panel 1 selects the maximum value of the hole diameter of the wire passing hole required by all air conditioner models in the refrigerating capacity 2200-2600 w, the panel 1 produced by the mold can be installed and used on all air conditioner models in the refrigerating capacity 2200-2600 w, and the model with smaller hole diameter is required to be installed and adjusted by installing the baffle plate 2. Thus, the cost of repeatedly opening the panel 1 is reduced, and the production speed of the air conditioning unit is improved.

Further, the second through hole 21 is provided with a plurality of holes including at least one weak current hole for passing the weak electric wire 31 and at least one strong current hole for passing the strong electric wire 32;

the number of the second through holes 21 is matched with the strong electric holes and the weak electric holes of the first through holes 11, and the aperture of each second through hole 21 is smaller than the aperture of the first through hole 11 matched with the second through hole.

Specifically, as shown in fig. 4 and 5, the baffle plate 2 is provided with two types of circular holes, one type of slightly larger circular holes is a strong current hole for passing the strong current wire 32, and the other type of slightly larger circular holes is a weak current hole for passing the weak current wire 31. Compared with the first through hole 11 arranged on the panel 1, the second through hole 21 arranged on the baffle plate 2 is not provided with an engineering hole for the engineering pipe to pass through, and only the strong current hole and the weak current hole are matched with each other in positions of the weak current hole and the strong current hole on the panel 1 after the baffle plate 2 is installed, and the weak current hole and the strong current hole on the baffle plate 2 are matched with each other in positions of the weak current hole and the strong current hole on the panel 1. The aperture of the strong electric holes on the baffle plate 2 is smaller than that of the strong electric holes on the panel 1, and the aperture of the weak electric holes on the baffle plate 2 is also smaller than that of the weak electric holes on the panel 1.

Here, for the sake of understanding, an air conditioner with a cooling capacity of 2200 to 2600w is still exemplified, and since the strong current hole and the weak current hole on the panel 1 are the maximum values of the pore diameters required by all models under the cooling capacity, if the pore diameters of the strong current hole and the weak current hole of the panel 1 meet the model requirements, the air conditioner is directly installed without installing the baffle plate 2, and if the pore diameters of the strong current hole and the weak current hole of the panel 1 are larger than the model requirements.

For example, because the north american wire passing hole is in an english system size, but not in an international standard, the hole diameter of the wire passing hole of the unit with the same refrigerating capacity is different from the north american area, so the standard in the north american area is smaller than the hole diameters of the strong current hole and the weak current hole required in the north american area, the baffle plate 2 is additionally arranged on the panel 1, the baffle plate 2 with the corresponding hole diameter is selected according to the requirement of the machine type, and the hole diameters of the strong current hole and the weak current hole of the panel assembly are regulated through the baffle plate 2, so that the panel assembly can meet the hole diameter requirements of the strong current hole and the weak current hole required by all the machine types under the refrigerating capacity.

For example, under the same refrigerating capacity, the aperture size of the first through hole 11 on the panel 1 is 2, the aperture size of the first through hole 11 on the panel 1 can meet the standard use in the North America area, but the aperture of the line passing hole is required to be 1.5 in the North America area, and then a baffle plate 2 with the aperture of the second through hole 21 being 1.5 is additionally arranged on the panel 1, so that the requirement of the North America area is met. Whether the installation is selected according to the requirement, so that the panel assembly can be adapted to all types under a certain refrigerating capacity, and the applicability of the panel assembly is improved.

Further, the edge of the panel 1 is also provided with a plurality of positioning holes 12 for connecting with an external air conditioner to fix the panel 1.

Specifically, a plurality of positioning holes 12 are further formed in the peripheral edge of the panel 1, the positioning holes 12 are through holes for screws to pass through, the panel 1 is connected with an air conditioner outdoor unit through screw fastening, and the screws enter through the plurality of positioning holes 12 formed in the panel 1 to install the panel 1 on the air conditioner outdoor unit. The panel 1 and the air conditioner external unit are firmly connected by the positioning holes 12, and are not easy to loosen.

Further, the knocking-off structure is arranged on the baffle plate 2, and comprises a filling plate 22 arranged in the second through hole 21 and a joint part 23 for connecting the filling plate 22 and the baffle plate 2; when the engagement portion 23 is broken, the filler plate 22 is separated from the barrier plate 2 to form the second through hole 21.

Specifically, as shown in fig. 6, the second through holes 21 of the baffle plate 2 are designed in a knock-out structure, the filling plate 22 is arranged in the holes, and the baffle plate 2 and the filling plate 22 are connected by a joint portion 23. It should be noted that, the knock-out structure is completed by laser cutting, the diameter of the outer circle of the knock-out structure is the aperture of the second through hole 21, the diameter of the outer circle is ensured to meet the requirement of North American safety rule during cutting, the filling plate 22 is not knocked off before the air conditioning unit is installed, the connecting part 23 of the knock-out structure is twisted during the unit installation until the connecting part 23 breaks, the filling plate 22 is separated from the baffle plate 2, and the remaining hole is the second through hole 21.

It should be noted that the aperture of the second through hole 21 is matched with the size of the via hole required by the model, so as to meet the requirements of various models.

For example, when the maximum value of the aperture requirement of all the machines under the same refrigerating capacity for the wire passing hole is 2, the aperture of the first through hole 11 of the panel 1 under the refrigerating capacity is 2, but when the machines under the refrigerating capacity are also required to have the apertures of 1.6, 1.7 and the like, the panel 1 is a mold piece which needs to be opened and manufactured, the change is time-consuming and labor-consuming, the baffle 2 is a small part which is easy to manufacture, and in order to meet the requirement, the baffle 2 with the apertures of the second through hole 21 of 1.6, 1.7 and the like is reproduced, so that the baffle 2 can adapt to the requirements of various machines under the refrigerating capacity, the second through hole 21 on the baffle 2 is in a knock-out structure, the filling plate 22 is not knocked out before being installed, the effect of preventing insects from entering the machine set is also played, and the safety of the product is improved to a certain extent.

Further, the panel assembly also includes a screw protecting structure 24 provided on the baffle 2; the screw protecting structure 24 includes a protruding portion provided on the baffle plate 2, one end surface of the protruding portion is disposed toward the insertion direction of the screw, and a space for accommodating the screw is provided between the end surface and the threaded hole 26.

When the panel 1 and the baffle 2 are fixed by the screws, the screws enter from the third through holes 14 on the panel 1, the screws are rotationally connected into the threaded holes 26 on the baffle 2, the tips of the screws are opposite to the end faces of the concave sheet metal on the baffle 2, the isolation screws are contacted with the strong wires 32 and the weak wires 31, the strong wires 32 and the weak wires 31 are prevented from being damaged by touching the screws, and the durability is improved.

Further, a gap of 0.6 mm-3mm is provided between the filler plate 22 and the baffle 2.

Specifically, the filling plate 22 and the baffle plate 2 are connected by the connection portion 23, and a certain width is reserved between the filling plate 22 and the baffle plate 2, because the filling plate 22 is easy to fall off during assembly, no foreign matters are prevented from entering the air conditioning unit before assembly, the width is optimally set to be 0.6mm-1.2mm, and the width is optimally set to be 1.2mm-3mm, so that the filling plate 22 is convenient to fall off, and a reserved gap is not easy to enter the foreign matters.

The invention also discloses an air conditioner which is provided with the panel assembly. The aperture of the panel assembly via hole can be adjusted by replacing the baffle plate on the panel assembly.
