Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to a valve bracket and an outdoor unit for air conditioning. Background Technology

[0002] A valve bracket is a support component for valves, used to secure them and prevent deformation during transportation, installation, and unit operation. Traditional valve brackets are typically regular rectangles, and the number and width of the valve bodies mounted on top determine the width of the valve bracket. This results in a relatively large valve bracket, which is not conducive to the compact design of outdoor units, especially those with dual compressors.

[0003] Chinese Patent Application No. 201922081197.7 discloses a valve support, including a valve body support and a main support. The valve body support is larger than the main support in the width direction of the valve support, so that at least one end of the main support in the width direction of the valve support forms a clearance space with the valve body support. However, it has the disadvantages of poor stability and easy deformation during use.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0005] The problem solved by this invention is that the existing valve support structure is unreasonable, resulting in large space occupation, high cost, poor stability, and easy deformation during use.

[0006] To address the aforementioned problems, the present invention provides a valve bracket, comprising: a mounting plate, wherein the mounting plate is provided with an assembly portion, the assembly portion including a mounting groove, the mounting groove having an open end, the open end being disposed through the edge of the mounting plate, the mounting groove being multiple and having a height difference along the height direction of the valve bracket; the height of the mounting plate is H3, the height of the valve bracket is H, wherein the value of H3 / H ranges from 21% to 24%.

[0007] This design uses an assembly section to stagger the different valve bodies at different heights on the mounting plate, resulting in a compact structure and minimal space occupation. It also improves the mechanical strength of the support plate, preventing valve body or pipeline loosening due to severe vibration of the valve bracket, and avoiding mutual collisions and wear caused by loosening. This ensures stable and reliable assembly of the valve bracket with pipelines. Preferably, the valve bracket further includes a support plate located at the lower part of the mounting plate. The support plate has weight-reducing holes, and a first folded edge is provided around the periphery of the weight-reducing holes.

[0008] Preferably, the valve bracket further includes a support plate disposed below the mounting plate. At least one side of the support plate has a second folded edge, the width of which gradually increases from top to bottom. The second folded edge forms an angle with the support plate. The second folded edge provides support to the support plate, preventing it from bending or deforming. The angle can be set as needed and can be any angle such as acute, right, or obtuse. Preferably, the angle is a right angle.

[0009] Preferably, the second folded edge has two symmetrically arranged on the left and right sides of the support plate. This arrangement provides vertical support to the support plate, balancing mechanical strength and production cost; it also features a simple structure and aesthetically pleasing appearance. Preferably, the second folded edge has at least one second rib, which strengthens the second folded edge and allows for slight deformation energy storage, preventing severe vibration of the valve support.

[0010] Preferably, the valve bracket further includes a connecting plate, and the support plate is vertically arranged. The support plate, connecting plate, and mounting plate are connected in sequence with bends. The support plate extends downward, and the mounting plate extends upward. An angle α1 is formed between the connecting plate and the support plate, and an angle α2 is formed between the connecting plate and the mounting plate, wherein 80° < α1 < 90° and 80° < α2 < 90°. This arrangement allows condensate generated by the valve body to drip down from the lower edge of the mounting plate and flow directly out from the refrigerant pipeline outlet, improving operational safety.

[0011] Preferably, at least one reinforcing rib is provided between the support plate and the connecting plate and / or between the connecting plate and the mounting plate. This arrangement can improve the mechanical strength of the valve bracket. The reinforcing rib includes, but is not limited to, one or more triangular ribs. Preferably, the connecting plate, support plate, and mounting plate are integrally formed.

[0012] Preferably, the valve bracket further includes a support portion connected to the base, the support portion including a second support portion connected to a support plate; the support portion also includes a first support portion connected to the second folded edge, the first support portion being perpendicular to the second support portion. This arrangement improves the assembly tightness of the valve bracket to the base, preventing the connection from loosening after long-term operation and causing severe vibration of the valve bracket. Preferably, the support portion further includes a third support portion, the third support portion and the first support portion being symmetrically arranged on the left and right sides of the second support portion, resulting in a compact structure and aesthetically pleasing appearance.

[0013] Preferably, the mounting slot includes a first mounting slot, a second mounting slot, and a third mounting slot, the second mounting slot being located between the first mounting slot and the third mounting slot, the third mounting slot being higher than the first mounting slot, and the second mounting slot being higher than the third mounting slot.

[0014] The first mounting slot, the second mounting slot, and the third mounting slot are respectively used to assemble the first valve, the second valve, and the third valve. Preferably, the first valve is a liquid valve with a vertical pipeline, the second valve is a maintenance valve, and the third valve is a gas valve with a vertical pipeline, with one end of the liquid valve and the gas valve connected to the indoor unit.

[0015] Preferably, at least one side of the first mounting groove and / or the second mounting groove and / or the third mounting groove is provided with a flange. This feature increases the force-bearing area between the mounting groove and the valve body, providing stable support for the valve during manual operation of the valve opening and closing, and preventing the valve bracket from deforming.

[0016] Preferably, the assembly part further includes a connecting hole, which corresponds to the mounting groove and is located on the side of the mounting groove. The connecting hole and the mounting groove cooperate to fix the valve body. This arrangement provides a tight assembly and a simple structure, facilitating production and processing. As an example of the present invention, the connecting hole includes a first hole and a second hole, which are symmetrically arranged on both sides of the mounting groove.

[0017] Compared with the prior art, the valve bracket of the present invention has the following advantages: 1) By setting the mounting groove in a staggered manner in the height direction, the width of the valve bracket can be reduced, the space occupied is small, and it is convenient for the miniaturization and compactness of air conditioners; 2) By setting the flange in the mounting groove to increase the structural strength, the groove deformation caused by manual operation of valve opening and closing, maintenance and other processes can be prevented; 3) By setting the weight reduction hole, second folding edge and other structures on the support plate to improve its structural stability, the amount used is small, and it is convenient for production and processing.

[0018] The present invention also provides an outdoor unit for an air conditioner, including a base, wherein the base is provided with the valve bracket described above. The outdoor unit for the air conditioner has the same beneficial effects as the valve bracket described above, and will not be described in detail here. Attached Figure Description

Detailed Implementation

[0026] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0027] Existing technology typically mounts the valve body at the same height as the valve bracket 1, resulting in a wide valve bracket 1 that is tightly fitted to the compressor, limiting the internal operating space, making it difficult to wrap the sound-absorbing cotton, and reducing production efficiency. Furthermore, the contact area between the valve and the valve bracket 1 is usually a thin sheet metal plate, which is easily deformed under stress during installation. Therefore, the applicant proposes the following technical solution:

[0028] Example 1

[0029] like Figure 1-5 As shown, a valve bracket 1 includes a support plate 11, with a mounting plate 12 disposed above the support plate 11. The mounting plate 12 has an assembly part 14 for mounting valve bodies, the assembly part 14 including mounting grooves 141. The mounting grooves 141 have an open end that extends through the edge of the mounting plate 12. There are multiple mounting grooves 141, and they have a height difference along the height direction of the valve bracket 1. The mounting grooves 141 are staggered along the height direction of the valve bracket 1, allowing different valve bodies to be installed at different heights, resulting in a more compact assembly and less internal space occupation. The width of the mounting grooves 141 gradually decreases from top to bottom, forming a V-shaped or U-shaped structure that is wider at the top and narrower at the bottom.

[0030] The assembly part 14 further includes a connecting hole 142, which corresponds to the mounting groove 141. The connecting hole 142 and the mounting groove 141 cooperate to fix the valve body. As an example of the present invention, the connecting hole 142 includes a first hole 1421 and a second hole 1422, which are symmetrically arranged on both sides of the width direction of the mounting groove 141. Preferably, at least one side of the mounting groove 141 is provided with a flange 143. This arrangement can increase the force-bearing area between the mounting groove 141 and the valve body, providing stable support for the valve during manual operation of the valve opening and closing, and preventing the valve bracket 1 from deforming.

[0031] As an example of the present invention, the mounting slot 141 includes a first mounting slot 1411, a second mounting slot 1412, and a third mounting slot 1413, respectively used for assembling the first valve 2, the second valve 3, and the third valve 4. The second mounting slot 1412 is located between the first mounting slot 1411 and the third mounting slot 1413. Preferably, the first valve 2 is a liquid valve with a vertical pipeline, the second valve 3 is a maintenance valve, and the third valve 4 is a gas valve with a vertical pipeline. One end of the liquid valve and the gas valve leads to the indoor unit. The specific structures of the first valve 2, the second valve 3, and the third valve 4 are prior art and will not be described in detail here. As an example of the present invention, the third mounting groove 1413 is raised by H2 = 9.5 mm at the center position of the first mounting groove 1411, and the second mounting groove 1412 is raised by H1 = 44.5 mm at the center position of the first mounting groove 1411, forming a staggered installation of the three valve support positions. As a result, the width W of the valve bracket 1 is shortened to 169 mm, the height is 351.5 mm, and the height-to-width ratio is 2, making its structure more compact and providing more space for sound-absorbing cotton wrapping and other installation and maintenance.

[0032] The support plate 11 is provided with weight-reducing holes 112, and at least one side of the support plate 11 is provided with a second flange 114, which forms a certain angle with the support plate 11. This arrangement can significantly reduce the weight of the valve bracket 1, and at the same time, the second flange 114 on the side strengthens the support plate 11 to form a surface contact, improving the stability of the assembly. Preferably, a first rib 111 is provided above the weight-reducing holes 112, and the first rib 111 extends horizontally. This arrangement can reduce the mutual transmission of vibrations during air conditioning operation and improve the connection and tightness between the valve body and the mounting plate 12.

[0033] Preferably, there are two second flanges 114, symmetrically arranged on the left and right sides of the support plate 11. Preferably, the width of the second flanges 114 gradually increases from top to bottom along the height direction. This arrangement can provide support for the support plate 11 in the vertical plane, balancing mechanical strength and production cost. Preferably, the second flanges 114 are provided with multiple second ribs 115 for storing energy during slight deformation, preventing significant deformation of the valve bracket 1.

[0034] The shape of the weight-reducing hole 112 can be set to any shape, such as circular or square, as needed. Preferably, a first folded edge 113 is provided on the periphery of the weight-reducing hole 112, which can strengthen the support plate 11 and further reduce the material used without affecting the mechanical strength. The area of ​​the weight-reducing hole 112 occupies 1 / 3 to 2 / 3 of the support plate 11. Preferably, the area of ​​the weight-reducing hole 112 occupies 1 / 2 of the support plate 11, which can balance mechanical strength and production cost.

[0035] As an example of the present invention, the valve bracket 1 further includes a connecting plate 13, one end of which is connected to the support plate 11, and the other end of which is connected to the mounting plate 12. Preferably, the connecting plate 13 extends horizontally, while the support plate 11 and mounting plate 12 extend vertically in opposite directions. The support plate 11, connecting plate 13, and mounting plate 12 are sequentially bent to form a stepped shape for the valve bracket 1. This arrangement prevents the valve body from fitting snugly against the support plate 11, thus avoiding the vertically positioned refrigerant pipeline where the valve body is located. Preferably, reinforcing ribs 15 are provided between the support plate 11 and the connecting plate 13 and / or between the connecting plate 13 and the mounting plate 12 to improve the mechanical strength of the valve bracket 1. The reinforcing ribs 15 include, but are not limited to, one or more triangular ribs. Preferably, the connecting plate 13, support plate 11, and mounting plate 12 are integrally formed.

[0036] As an example of the present invention, the valve bracket 1 further includes a support portion 16, which is located at the end of the support plate 11 away from the mounting plate 12 and is used to connect with the outdoor unit base (not shown in the figure). Preferably, the support portion 16 includes a first support portion 161 connected to the second folded edge 114 for supporting the valve bracket 1 in a first direction; the support portion 16 also includes a second support portion 162 connected to the support plate 11 for supporting the valve bracket 1 in the first direction. The support portion 16 further includes a third support portion 163, which, along with the first support portion 161, is symmetrically arranged on the left and right sides of the second support portion 162.

[0037] Example 2

[0038] During use, the applicant discovered that the reduced width of the support plate 11 made it prone to bending and deformation during assembly, and also caused excessive noise due to vibration transmission during compressor operation. Therefore, the applicant proposes the following technical solution.

[0039] A valve support 1 includes a mounting plate 12 with mounting grooves 141 for mounting valve bodies. Each mounting groove 141 has an open end that extends through the edge of the mounting plate 12. Multiple mounting grooves 141 are provided, each with a height difference along the height direction of the valve support 1. The height of the mounting plate 12 is H3, and the height of the valve support is H, where the ratio of H3 / H ranges from 21% to 24%. This design allows different valve bodies to be staggered and mounted at different heights on the mounting plate, resulting in a compact structure and minimal space occupation within the machine.

[0040] Preferably, the valve bracket further includes a support plate 11 disposed at the lower part of the mounting plate 12. The support plate 11 has weight-reducing holes 112, and a first folded edge 113 is provided around the weight-reducing holes 112. This arrangement can improve the mechanical strength of the support plate 11, avoid the valve body or pipeline from loosening due to severe vibration of the valve bracket, and prevent mutual collision and wear caused by loosening; ensuring that the valve bracket is stable and reliable when assembled with pipelines.

[0041] As an example of the present invention, a second flange 114 is provided on at least one side of the support plate 11, forming a certain angle with the support plate 11. This arrangement can support the support plate 11 of the valve bracket 1, preventing it from bending and deforming. Preferably, the width of the second flange 114 gradually increases from top to bottom, and there are two second flanges 114, symmetrically arranged on the left and right sides of the support plate 11. This arrangement can support the support plate 11 in the vertical plane, balancing mechanical strength and production cost; the structure is simple and aesthetically pleasing. Preferably, the second flange 114 is provided with at least one second rib 115, which can strengthen the second flange 114 and achieve slight deformation energy storage, preventing the valve bracket 1 from vibrating violently; the structure is reasonable and easy to manufacture. The support plate 11 is provided with a weight-reducing hole 112, a first rib 111 is provided above the weight-reducing hole 112, and a first flange 113 is provided around the weight-reducing hole 112. This setup reduces production costs while increasing the mechanical strength of the support plate 11, preventing the valve body or pipeline from loosening due to severe vibration of the valve bracket 1, as well as the mutual collision and wear problems caused by loosening.

[0042] Preferably, the valve bracket 1 further includes a connecting plate 13. The support plate 11, connecting plate 13, and mounting plate 12 are connected in sequence with a bend. The connecting plate 13 forms an angle α with the support plate 11 and / or mounting plate 12, where 80° < α < 90°. During air conditioner operation, condensate is easily generated due to the temperature difference between the valve body and the outside environment. The condensate flows along the valve bracket 1 to the base, posing a safety hazard to the operation of the outdoor unit. This design allows the condensate generated by the valve body to drip down from the lower edge of the mounting plate 12 and flow directly out from the pipe outlet, improving operational safety.

[0043] Preferably, the valve bracket 1 further includes a support portion 16, which is used to connect the support plate 11 and / or the second folded edge 114 to the outdoor unit base (not shown in the figure). As an example of the present invention, the support portion 16 includes a second support portion 162 connected to the support plate 11, used to fix the valve bracket 1 in a first direction; the support portion 16 also includes a first support portion 161 and / or a third support portion 163, used to cooperate with the second support portion 162 to fix the valve bracket 1 in a second direction. Preferably, the first direction and the second direction are perpendicular to each other. As an example of the present invention, the third support portion 163 and the first support portion 161 are symmetrically arranged on the left and right sides of the second support portion 162, resulting in a compact structure and aesthetically pleasing appearance.

[0044] Preferably, at least one side of the mounting groove 141 is provided with a flange 143. This configuration increases the force-bearing area between the mounting groove 141 and the valve body, providing stable support for the valve during manual operation of the valve and preventing deformation of the valve bracket 1. A connecting hole 142 is provided on the side of the mounting groove 141, and the connecting hole 142 and the mounting groove 141 cooperate to fix the valve body. As an example of the present invention, the connecting hole 142 includes a first hole 1421 and a second hole 1422, which are symmetrically arranged on both sides of the mounting groove 141.

[0045] As an example of the present invention, the mounting groove 141 includes a first mounting groove 1411, a second mounting groove 1412, and a third mounting groove 1413, which are respectively used to assemble the first valve 2, the second valve 3, and the third valve 4. The second mounting groove 1412 is located between the first mounting groove 1411 and the third mounting groove 1413. Preferably, the third mounting groove 1413 is raised by H2 = 9.5mm at the center position of the first mounting groove 1411, and the second mounting groove 1412 is raised by H1 = 44.5mm at the center position of the first mounting groove 1411, forming a staggered installation of the three valve support positions. As a result, the width W of the valve bracket 1 is shortened to 169mm, the height is 351.5mm, the height-to-width ratio is 2, the structure is more compact, and more space is provided for sound-absorbing cotton wrapping and other installation and maintenance. Preferably, the first valve 2 is a liquid valve with a vertical pipeline, the second valve 3 is a maintenance valve, and the third valve 4 is a gas valve with a vertical pipeline. One end of the liquid valve and the gas valve leads to the indoor unit. The specific structures of the first valve 2, the second valve 3, and the third valve 4 are existing technologies and will not be described in detail here.

[0046] This invention also proposes an outdoor unit for an air conditioner, which can be a cabinet-type outdoor unit, a wall-mounted outdoor unit, a ceiling-mounted outdoor unit, etc.; the outdoor unit can be a single-split unit or a multi-split unit. The outdoor unit includes a base, on which the valve bracket 1 is mounted. Besides the valve bracket 1, the outdoor unit also includes components such as a compressor, evaporator, gas separator, and refrigerant piping. Since the specific structures and assembly relationships of these components are existing technology, they will not be described in detail here.

[0047] It should be noted that the directional terms mentioned in the embodiments of the present invention are all based on the normal assembly and installation of the air conditioner. "Up" refers to the upper direction or space of the air conditioner during normal assembly and installation, "down" refers to the lower direction or space of the air conditioner during normal assembly and installation, and "horizontal" refers to the horizontal plane direction of the air conditioner during normal assembly and installation. The terms "left", "right", "front", "back", etc. are the same and will not be elaborated here. As in the conventional understanding, the "horizontal" direction is perpendicular to the "up and down" direction or the "vertical" direction.

[0048] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
