Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a fixing structure for fixing an electronic expansion valve, an outdoor unit and an air conditioner. Background Art

[0002] First, there are many electronic expansion valves in the one-to-many model. In the trend of miniaturization of the outer shell, the space available for placing the electronic expansion valve is very small, resulting in complex pipeline design and difficult production and welding operations. Secondly, the compressor is set at the bottom of the air conditioner outer unit, and there is no space for the electronic expansion valve, so the electronic expansion valve is placed in the space above the compressor, and the space position is higher than the compressor, located in the upper middle part of the shell. In order to facilitate the placement of the electronic expansion valve in the upper space of the outer shell, the center of gravity of the entire valve body is top-heavy at the top, and the electronic expansion valve is completely supported by the rigidity of the connected pipeline itself, which leads to the electronic expansion valve shaking violently and with a large amplitude during the packaging, transportation and testing of the whole machine, which leads to the breakage of the connected pipeline, which has disadvantages for product development, production and after-sales. Finally, in order to facilitate the fixing of multiple electronic expansion valves, an electronic expansion valve fixing assembly is also provided in the prior art. Multiple electronic expansion valve bodies need to be fixed by multiple parts such as a first fixing plate, a second fixing plate, a third fixing plate, a fourth fixing plate, and a fixing ring.

DETAILED DESCRIPTION

[0046] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0047] like Figure 2 As shown, the present invention provides a fixing structure 70, including a first plate body 1 and a second plate body 2 arranged in an L shape, the first plate body 1 is vertically arranged to be fitted and connected with the partition 10, because the partition 10 is a flat plate structure, the first plate body 1 is also a flat plate structure, the two can be fitted together and connected by hooks 11 and screws; the second plate body 2 is horizontally arranged to be connected with the valve bracket 20; it should be noted that the valve bracket 20 is vertically arranged parallel to the partition 10, and the fixing structure 70 is connected between the valve bracket 20 and the partition 10, thereby forming a structural feature that the electronic expansion valve 50 is fixed to the top of the compressor 30; in order to facilitate the installation and fixing of the electronic expansion valve 50, a fixing groove 3 is provided on the second plate body 2, and the electronic expansion valve 50 is installed in the fixing groove 3. Considering the need to prevent the electronic expansion valve 50 from shaking left and right, it is necessary to limit the electronic expansion valve 50 in a certain horizontal direction, so in this embodiment, as Figure 8 As shown, the two side edges of the fixing groove 3 of the second plate body 2 extend downward to form side wall plates. When the electronic expansion valve 50 is inserted into the fixing groove 3, the side walls of the fixing groove 3 and the side wall plates can both limit and fix the electronic expansion valve 50, thereby minimizing the shaking of the electronic expansion valve 50. It also includes a self-locking component 4, which is arranged at the fixing groove 3 to lock the position of the electronic expansion valve 50. Specifically, the self-locking component 4 is arranged at the side wall plate at the bottom of the fixing groove 3, such as Figure 8 , Fig.10 , Fig.11 and Fig.12 shown.

[0048] The fixing structure 70 provided by the present invention comprises a first plate body 1, a second plate body 2 and a self-locking assembly 4. The electronic expansion valve 50 is fixed by the self-locking fixing structure 70, which can reduce the vibration and noise during the operation of the whole machine and thus reduce the stress and strain of the pipeline. At the same time, it prevents the valve body from shaking violently under harsh road conditions during transportation, thereby causing the pipeline to be fatigued and fractured, thereby reducing the product failure rate and improving the product quality. At the same time, the self-locking fixing structure 70 has the characteristics of simple structure, and for a smaller shell space, the layout is flexible, and a small-sized external machine can be selected for development, thereby reducing the development cost of the whole machine. At the same time, the number of parts to be assembled is small and the efficiency is high. There is no need to develop special tooling, and it is convenient to fix multiple electronic expansion valves 50 by welding.

[0049] Considering that the air conditioner in this embodiment is a one-to-many air conditioner with multiple electronic expansion valves 50, in this embodiment, the number of fixed grooves 3 on the fixed structure 70 is multiple, and all the fixed grooves 3 are distributed circumferentially along the second plate body 2 to form an annular installation of all the electronic expansion valves 50.

[0050] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig. 9 As shown, there are five fixing grooves 3 on the second plate body 2, which are respectively located at the three side edges of the second plate body 2, with three fixing grooves 3 being arranged at the first edge, one fixing groove 3 being arranged at the second edge, and one fixing groove 3 being arranged at the third edge.

[0051] For the convenience of installation, in this embodiment, the fixing groove 3 is a U-shaped groove dug inward from the edge of the second plate body 2. In order to save space and to be able to install all the electronic expansion valves 50, the depth of the fixing groove 3 is different, that is, the depth of each fixing groove 3 is different, such as Fig. 9 shown.

[0052] like Figure 1-Figure 12 As shown, the self-locking assembly 4 includes self-locking buckles 41 relatively arranged on both sides of the fixing groove 3; the entrance spacing b between the two self-locking buckles 41 is smaller than the lower diameter e of the electronic expansion valve 50; the lower diameter e of the electronic expansion valve 50 is not greater than the width c of the fixing groove 3.

[0053] like Figure 10-12 As shown, the self-locking buckle 41 includes a telescopic slot 42 and an elastic card 43; wherein:

[0054] The telescopic groove 42 extends along the length direction of the side wall of the fixing groove 3; specifically, Figure 10-12As shown, the telescopic slot 42 is provided on the side wall plate at the bottom of the fixed slot 3; the telescopic slot 42 is a through slot;

[0055] The elastic card 43 is fixed in the telescopic slot 42 in a cantilever form, and the length i of the elastic card 43 is smaller than the length k of the telescopic slot 42; the width j of the elastic card 43 is smaller than the width n of the telescopic slot 42; the distance between the end of the elastic card 43 and the bottom of the fixed slot 3 is adapted to the specifications of the lower part of the electronic expansion valve 50, that is, when the electronic expansion valve 50 is installed in the fixed slot 3, the end of the elastic card 43 should just abut against the lower outer wall of the electronic expansion valve 50 to limit the position of the electronic expansion valve 50 and prevent it from tilting, tipping, shaking, etc.

[0056] As an optional embodiment of the present invention, Fig. 9 As shown, the elastic card 43 includes a first arm 44, a second arm 45 and a third arm 46 which are arranged in sequence; wherein:

[0057] The first arm 44 is arranged parallel to the telescopic slot 42;

[0058] The second arm 45 and the third arm 46 are arranged in a V shape, and a second angle 48 is formed therebetween. To achieve a good abutment effect, the second angle 48 is an acute angle, for example, 30-60°. The optimal angle is 45°, which is the best guiding angle.

[0059] The second arm 45 is inclined toward the center of the fixing slot 3 , and forms a first angle 47 with the first arm 44 . Specifically, in order to form a good elastic structure, the first angle 47 is an obtuse angle, for example, 110-145°.

[0060] A third angle 49 is formed between the two third arms 46 of the two opposite elastic clips 43 , and the third angle 49 is an obtuse angle.

[0061] In order to improve the stabilization effect and increase the contact area, a circular arc fixing portion 31 matching the curvature of the lower portion of the electronic expansion valve 50 is provided at the bottom of the fixing groove 3 .

[0062] like Figure 1-Figure 12 As shown, for easy installation, in this embodiment, a hook 11 and a first mounting hole are provided on the top of the first plate body 1, and the hook 11 is used to be hung on the partition 10; the first mounting hole is used to be connected to the partition 10 by screws. During installation, the first plate body 1 is hung on the top of the partition 10 by the hook 11, and then connected to the partition 10 by screws.

[0063] In order to facilitate installation, in this embodiment, a positioning slot 21 and a second mounting hole are provided on the edge of the second plate body 2. The positioning slot 21 is used to engage with the tongue structure 60 on the valve body bracket; the second mounting hole is used to connect with the valve body bracket by screws. During installation, the positioning slot 21 of the second plate body 2 is inserted into the tongue structure 60 of the valve bracket 20, and finally connected with the valve bracket 20 by screws.

[0064] like Figure 1-Figure 12 As shown, an outdoor unit provided by the present invention includes a chassis 40, a compressor 30, a valve bracket 20, an electronic expansion valve 50, a partition 10 and a fixing structure 70; wherein:

[0065] The compressor 30 is placed on the chassis 40;

[0066] The partition plate 10 and the valve support 20 are respectively located on both sides of the compressor 30;

[0067] The fixing structure 70 is located above the compressor 30, and one end is connected to the upper part of the partition 10, and the other end is connected to the top of the valve bracket 20;

[0068] The electronic expansion valve 50 is fixed on the fixing structure 70 .

[0069] The outdoor unit of the present invention includes a fixing structure 70, on which a plurality of fixing grooves 3 for clamping an electronic expansion valve 50 are arranged. The surrounding arrangement of the electronic expansion valve 50 is more compact and occupies less space, and can be placed on the top of the compressor 30, thereby effectively utilizing the shell space. The symmetrical elastic self-locking buckles arranged on the sides of the fixing grooves 3 in the fixing structure 70 effectively fix the electronic expansion valve 50, reduce vibration noise during operation and large-scale shaking during transportation, avoid fatigue fracture of the lower connecting section pipeline, and improve product reliability. At the same time, the number of parts is small, and the corresponding production and assembly efficiency is improved, and the use of materials such as damping blocks and wire ties is avoided. Using a smaller shell can reduce the cost of the entire machine.

[0070] like Figure 1-Figure 12 As shown, the present invention provides an air conditioner, including the above-mentioned outdoor unit.

[0071] It should be noted that the outdoor unit of the present invention is a one-to-many outdoor unit.

[0072] The outdoor unit includes a compressor 30, a valve bracket 20, a chassis 40, a condenser component 90, and a partition 10; wherein the compressor 30, the valve bracket 20, the condenser component 90, and the partition 10 are all placed on the chassis 40; the compressor 30 is connected to the pipeline on the valve bracket 20 through the pipeline structure 80, and the pipeline of the electronic expansion valve 50 is connected to a part of the pipeline on the valve bracket 20 and also connected to the pipeline on the condenser component 90. During installation, the fixing structure 70 is first hung on the partition 10 through the hook 11 on one side, and the positioning card slot 21 on the other side is inserted into the tongue structure 60 of the valve bracket 20, and finally the screws are respectively passed through the first mounting hole and the second mounting hole to lock the front and rear sides, so that the electronic expansion valve 50 is placed in the space above the compressor 30. The electronic expansion valve 50 is pre-assembled. A plurality of electronic expansion valves 50 are pre-assembled into the fixing groove 3 opened on the second plate body 2 in the fixing structure 70. The side wall plates at the bottom of both sides of the fixing groove 3 are symmetrically provided with self-locking components 4. When the electronic expansion valve 50 is pushed in parallel along the fixing groove 3 and hits the self-locking component 4, the self-locking buckle 41 in the self-locking component 4 is elastically deformed and bent and retreats into the telescopic groove 42. When the entrance spacing b between the two self-locking buckles is greater than or equal to the lower diameter e of the electronic expansion valve 50, the electronic expansion valve 50 can pass through and be pushed straight to the bottom fixing portion 31 of the fixing groove 3. At the same time, the self-locking component 4 returns to its original position. In this way, the entrance spacing b between the two self-locking buckles 41 is less than the lower diameter e of the electronic expansion valve 50. The self-locking buckle 41 supports the electronic expansion valve 50, and the electronic expansion valve 50 cannot retreat and completes self-locking. The assembly process of the electronic expansion valve 50 is completed. The self-locking buckle 41 is arranged on the side wall plate at the bottom of the fixed groove 3, and forms a first angle 47 through the first arm 44 and the second arm 45, and the first angle 47 is an obtuse angle; the second arm 45 is connected with the third arm 46 to form a second angle 48. In order to make the self-locking buckle 41 elastic, it is necessary to open a long strip expansion groove 42 on the side wall plate at the bottom of the fixed groove 3, the length k of the expansion groove 42, the length i of the elastic card 43, and the length i of the elastic card 43 is required to be less than the length k of the expansion groove 42, and the gap m between the elastic card 43 and the expansion groove 42 should be ≥1mm. Only then can the self-locking buckle 41 processed have specific elasticity and strength.

[0073] The above structure can achieve stable fixation of multiple electronic expansion valves 50, so that their operation is stable without noise problems and the transportation process is firm and reliable. The product will not be shaken violently due to harsh transportation conditions, causing fatigue fracture of the connecting pipeline, thereby improving the reliability and quality of the product.

[0074] In order to facilitate installation while limiting the position of the electronic expansion valve 50 , the lower diameter e of the electronic expansion valve 50 minus the fixed diameter D of the fixing groove 3 ≥ 1 mm; the lower diameter e of the electronic expansion valve 50 is smaller than the upper diameter f.

[0075] 0<the width c of the fixing groove 3-the lower diameter e of the electronic expansion valve 50≤1; through the above structure, a certain equipment gap is reserved, and on the basis of ensuring the assembly efficiency, it can also ensure that the gap is sufficient, and the stable fixation of the electronic expansion valve 50 can be guaranteed.

[0076] The air conditioner of the present invention can reduce the vibration and noise during the operation of the whole machine by fixing the electronic expansion valve 50 through the self-locking fixing structure 70, thereby reducing the stress and strain of the pipeline; the fixing groove 3 of the electronic expansion valve 50 is arranged on the second plate body 2 of the fixing structure 70, and the surrounding arrangement is more compact and occupies less space. At the same time, it can be placed on the top of the compressor 30 to effectively utilize the shell space. At the same time, symmetrical elastic self-locking buckles are arranged on the side walls on both sides of the bottom of the fixing groove 3 to effectively fix the electronic expansion valve 50, reduce the vibration noise during operation and the large-scale shaking during transportation, and avoid fatigue fracture of the lower connecting section pipeline structure 80. Improve the reliability of the product. At the same time, the number of parts is small, and the corresponding production and assembly efficiency is improved, avoiding the use of materials such as damping blocks and wire ties, using a smaller shell, and reducing the cost of the whole machine.
