Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly to a sealed pipe assembly for an air conditioner, an air conditioner, and a recreational vehicle. Background Art

[0002] With the continuous improvement of living standards, people have higher and higher requirements for the living environment. In order to obtain a comfortable temperature and humidity environment, air conditioners have become one of the essential devices in people's lives.

[0003] According to different structures, air conditioners can be divided into two types: integrated air conditioners and split air conditioners. Among them, an integrated air conditioner arranges functional components such as a compressor, a condenser, an expansion device, and an evaporator in an independent housing. A split air conditioner includes an indoor unit and an outdoor unit spaced apart from each other. An indoor heat exchanger and a corresponding indoor fan are arranged in the indoor unit, and a compressor, an outdoor heat exchanger, an outdoor fan, an expansion device, etc. are arranged in the outdoor unit.

[0004] Whether it is an integrated air conditioner or a split air conditioner, each functional component is sequentially connected by a refrigerant pipe to form a refrigeration circuit that allows a refrigerant medium to circulate therein. Conventional air conditioners usually use a heat-insulating pipe made of a heat-insulating material (such as foamed polyethylene, etc.) to wrap the refrigerant pipe, preventing the refrigerant pipe from being exposed, avoiding heat exchange between the air in the external environment and the refrigerant pipe and reducing the refrigeration efficiency, and also preventing water vapor in the air from contacting the refrigerant pipe and turning into condensed water. However, when using a heat-insulating pipe to wrap the refrigerant pipe, it is necessary to tightly wrap the heat-insulating pipe on the slender refrigerant pipe, which is extremely inconvenient to operate, resulting in higher processing costs and maintenance costs for the air conditioner.

[0005] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0006] In order to solve the technical problem that it is inconvenient to operate when using a heat-insulating pipe to wrap the refrigerant pipe of an air conditioner in the prior art, the present invention provides a sealed pipe assembly for an air conditioner. The sealed pipe assembly includes: a sealed pipe having opposite first and second ends, and a hollow cavity is formed inside the sealed pipe; a sealed pipe pressing plate arranged on the first end and adapted to form a fixed connection with a terminal block of the air conditioner, and the sealed pipe pressing plate is configured to form a limiting cavity together with the terminal block for clamping the refrigerant pipe of the air conditioner, so that the refrigerant pipe can extend into the cavity after passing through the limiting cavity; and a sealed pipe cover arranged on the second end, and the sealed pipe cover is adapted to be fixed at a predetermined installation position having a through hole allowing the refrigerant pipe to pass through and can seal the through hole.

[0007] The sealed tube assembly for an air conditioner according to the present invention includes: a sealed tube, a sealed tube pressing plate, and a sealed tube cover. The sealed tube has opposite first and second ends, and a hollow cavity is formed inside the sealed tube to form a space for accommodating the refrigerant tube of the air conditioner. The sealed tube pressing plate is arranged on the first end and is adapted to form a fixed connection with the terminal block of the air conditioner. In the assembled state, the sealed tube pressing plate and the terminal block together enclose a limiting cavity for clamping the refrigerant tube, so that the refrigerant tube can not only be firmly constrained in the limiting cavity, but also conveniently extend into the cavity through the limiting cavity. The sealed tube cover is arranged on the second end and is adapted to be fixed at a predetermined installation position. A through hole allowing the refrigerant tube to pass through is provided at the predetermined installation position for connection with other components of the air conditioner. In the assembled state, the sealed tube cover can seal the through hole, so that the exposed refrigerant tube can be covered by the sealed tube, playing a role in protection and aesthetics. Further, the two ends of the sealed tube are respectively fixedly connected to the terminal block and the predetermined installation position through the sealed tube pressing plate and the sealed tube cover, so that a relatively sealed cavity is formed inside the whole sealed tube, and the refrigerant tube is isolated from the air in the external environment, which not only plays a role in heat preservation, ensures the refrigeration efficiency, but also can prevent the moisture in the external environment from contacting the refrigerant tube and turning into condensate. More importantly, when sealing the refrigerant tube, only need to sleeved the sealed tube on the refrigerant tube, and then fix the sealed tube pressing plate and the sealed tube cover on the terminal block and the predetermined installation position respectively, then a good sealing effect can be achieved, without covering other components (such as heat preservation tubes, etc.) on the slender refrigerant tube, reducing the operation difficulty, and correspondingly reducing the processing cost and maintenance cost.

[0065] Next, in conjunction with Figures 4 - 11 the embodiments of the sealing tube assembly 2 for the air conditioner 1 of the present invention will be introduced in detail.

[0066] As Figure 4 shown, in one or more embodiments, the sealing tube assembly 2 for the air conditioner 1 of the present invention includes components such as a sealing tube 20, a sealing tube pressing plate 30, and a sealing tube cover 40.

[0067] Continuing to refer to Figure 4 , Figure 8 and Figure 11 , in one or more embodiments, the sealing tube 20 includes a sealing tube body 21 at the middle, a first clamping portion 22a and a second clamping portion 22b respectively located at both ends of the sealing tube body 21. The sealing tube body 21 has opposite first end 20a and second end 20b. Based on Figure 4In the orientation shown, the first end 20a is the left end, and the second end 20b is the right end. The first clamping portion 22a is located on the first end 20a, and the second clamping portion 22b is located on the second end 20b. The sealing tube pressing plate 30 is matched with the first clamping portion 22a and fixed on the first end 20a, and the sealing tube cover 40 is matched with the second clamping portion 22b and fixed on the second end 20b. In one or more embodiments, the sealing tube body 21, the first clamping portion 22a, and the second clamping portion 22b are integrally formed by an injection molding process using a suitable resin material (such as PE, PVC, etc.) to simplify the manufacturing process. The entire sealing tube 20 forms a hollow cavity 23 to provide a suitable space for accommodating the refrigerant tube 14 and the wire harness 13.

[0068] Continue to refer to Figure 4 , in one or more embodiments, the sealing tube body 21 is a corrugated tube 211 with a corrugated structure, enabling the sealing tube body 21 to be conveniently telescoped and bent. This can not only improve the assembly efficiency but also adjust the length of the sealing tube body 21 according to actual needs, thus meeting diverse assembly requirements. In one or more embodiments, the corrugated tube 211 has a longitudinal cross-section that is approximately square with rounded corners, giving the corrugated tube 211 a regular and aesthetic appearance. Alternatively, the corrugated tube 211 can also be set to other suitable cross-sections.

[0069] Continue to refer to Figure 8 and Figure 11 , in one or more embodiments, the first clamping portion 22a and the second clamping portion 22b are symmetrically arranged with respect to a vertical plane perpendicular to the center line of the sealing tube body 21. Through the above arrangement, the entire sealing tube 20 can have a symmetric and regular structure, facilitating processing and assembly. Alternatively, the first clamping portion 22a and the second clamping portion 22b can also be set to different structures. In one or more embodiments, each of the first clamping portion 22a and the second clamping portion 22b includes a circumferential connecting wall 221 and a clamping protrusion 222. The circumferential connecting wall 221 is configured to extend in a direction away from the sealing tube body 21 along the center line of the sealing tube body 21 from the circumferential edge of the sealing tube body 21. The setting of the circumferential connecting wall 221 can increase the contact area between the sealing tube pressing plate 30 and the first clamping portion 22a, as well as between the sealing tube cover 40 and the second clamping portion 22b, thereby improving the reliability of the connection. The clamping protrusion 222 is configured to extend radially outward from the circumferential connecting wall 221 along the sealing tube body 21. The clamping protrusion 222 can easily form a clamping fit with the first clamping cavity 321 on the sealing tube pressing plate 30 and the second clamping cavity 424 on the sealing tube cover 40.

[0070] As Figures 4 - 9As shown, in one or more embodiments, the sealed tube pressing plate 30 includes a connecting bracket 31, a limiting bracket 32, and a fixing bracket 33 that are connected to each other. The connecting bracket 31, the limiting bracket 32, and the fixing bracket 33 can be integrally formed by an injection molding process using a suitable resin material (such as ABS, PP, etc.) to simplify the manufacturing process. The entire sealed tube pressing plate 30 has a generally U-shaped structure to form a fixed connection with the first clamping portion 22a and the terminal block 12.

[0071] Continuing to refer to Figure 6 and Figure 7 , the connecting bracket 31 has a U-shaped body 311. In the assembled state, the opening of the U-shaped body 311 faces the sealed tube 20, and the inner walls of the U-shaped body 311 are both abutted against the circumferential connecting wall 221 of the first clamping portion 22a, so that there is a large contact area between the connecting bracket 31 and the circumferential connecting wall 221, thereby improving the reliability of the connection. In one or more embodiments, two lugs extending in opposite directions from each other are formed at both ends of the U-shaped body 311, namely a first lug 312a and a second lug 312b. Each of the first lug 312a and the second lug 312b is configured to extend vertically outward from the U-shaped body 311. A second fixing hole 3121 is provided on each of the first lug 312a and the second lug 312b. The second fixing hole 3121 can be matched with the second fixing post 1214 on the terminal block base 121 and form a fixed connection through a fastener.

[0072] Continuing to refer to Figure 6 and Figure 7 , the limiting bracket 32 is configured to extend radially outward along the circumferential edge of the U-shaped body 311 on the side away from the sealed tube body 21. Through the above arrangement, the limiting bracket 32 encloses a space slightly larger than the connecting bracket 31 to be matched with the clamping protrusion 222 on the first clamping portion 22a to form a clamping fit.

[0073] Continuing to refer to Figures 6 - 8 , the fixing bracket 33 is located on the side of the limiting bracket 32 away from the connecting bracket 31. The fixing bracket 33 includes a cross plate 331, a first vertical plate 332a, and a second vertical plate 332b. The cross plate 331 extends substantially in the horizontal direction. The first vertical plate 332a and the second vertical plate 332b are respectively located on the left and right sides of the cross plate 331 and extend substantially in the vertical direction.

[0074] Continuing to refer to Figures 7 - 8, the transverse plate 331 has a generally rectangular shape. In the assembled state, the transverse plate 331 abuts against the limiting member 1222 of the terminal block 12, such that the originally upward-opening first refrigerant pipe limiting groove 12223 and the second refrigerant pipe limiting groove 12224 are surrounded by the transverse plate 331 to form a closed limiting cavity 34, thereby stably clamping the first refrigerant pipe 141 and the second refrigerant pipe 142 constrained in the first refrigerant pipe limiting groove 12223 and the second refrigerant pipe limiting groove 12224 in the limiting cavity 34. Two first fixing holes 3311 spaced from each other are formed in the transverse plate 331. Each first fixing hole 3311 can be mated with a corresponding first fixing post 1223 on the terminal block protective cover 122, so as to fix the fixing bracket 33 to the terminal block protective cover 122 through fasteners. Alternatively, the number of the first fixing holes 3311 can also be set to other suitable numbers more or less than two, as long as it can be mated with the first fixing post 1223. In one or more embodiments, a boss 33111 extending vertically upward is formed on the upper surface of the transverse plate 331, and a central through hole 33112 is provided at the center of the boss 33111 to form the first fixing hole 3311. Through the above arrangement, not only the strength of the first fixing hole 3311 can be enhanced, but also the vertical height of the first fixing hole 3311 can be appropriately increased, making the structure more stable when the first fixing post 1223 is inserted into the first fixing hole 3311. Refer to Figure 8 , in one or more embodiments, four limiting grooves 33113 evenly spaced from each other along the circumferential direction of the first fixing hole 3311 are formed on the lower surface of the transverse plate 331. Each limiting groove 33113 extends radially outward along the first fixing hole 3311. Each limiting groove 33113 can receive a corresponding limiting rib 12232 on the first fixing post 1223, thereby further improving the reliability of the connection between the first fixing post 1223 and the first fixing hole 3311. Alternatively, the number of the limiting grooves 33113 can also be set to other suitable numbers more or less than four, as long as it can be mated with the limiting rib 12232. Refer to Figure 7 , in one or more embodiments, four reinforcing ribs 33114 evenly spaced from each other along the circumferential direction are formed on the outer circumferential wall of each boss 33111. Each reinforcing rib 33114 is configured to extend radially outward from the outer circumferential wall. The arrangement of the reinforcing ribs 33114 can enhance the rigidity and strength of the boss 33111. Alternatively, the number of the reinforcing ribs 33114 can also be set to other suitable numbers more or less than four, such as three, five, etc.

[0075] Continue to refer to Figures 7 - 8, in one or more embodiments, a positioning hole 3312 is further provided on the transverse plate 331 and located between two first fixing holes 3311. The positioning hole 3312 is configured to receive a corresponding positioning post 1224 on the terminal block protective cover 122, so as to further improve the assembly efficiency and assembly accuracy of the sealing tube pressing plate 30. In one or more embodiments, four reinforcing ribs (not marked in the figure) are formed on the outer circumferential wall of the positioning hole 3312 at evenly spaced intervals in the circumferential direction to enhance the rigidity and strength of the positioning hole 3312. Further, reinforcing ribs may also be provided at other appropriate positions on the upper surface of the transverse plate 331 according to actual needs to enhance the rigidity and strength of the entire transverse plate 331, for example, between the positioning hole 3312 and the first fixing hole 3311.

[0076] Continue to refer to Figures 7 - 8 , the first vertical plate 332a and the second vertical plate 332b are arranged opposite to each other. In one or more embodiments, each of the first vertical plate 332a and the second vertical plate 332b includes a upper section 3321, a middle section 3322 and a lower section 3323 connected in sequence. Among them, the upper section 3321 extends substantially in the vertical direction, the middle section 3322 extends vertically outward from the lower part of the upper section 3321, and the lower section 3323 extends vertically downward from the side of the middle section 3322 away from the upper section 3321. In the assembled state, the middle section 3322 extending substantially in the transverse direction can abut against the terminal block protective cover 122 to improve the connection stability between the sealing tube pressing plate 30 and the terminal block 12. In one or more embodiments, a substantially rectangular positioning opening 33231 is provided in the lower section 3323. The positioning opening 33231 is configured to receive a corresponding positioning protrusion 1213 on the terminal block base 121 to improve the assembly efficiency and assembly accuracy of the sealing tube pressing plate 30.

[0077] As Figures 10 - 11As shown, in one or more embodiments, the sealed tube cover 40 includes a bottom plate 41 and a housing 42 that mate with each other to enclose a receiving cavity 43 that allows the refrigerant tube 14 and the wire harness 13 to bend and turn therein. The bottom plate 41 has a bottom plate body 411 that is generally rectangular with rounded corners. The bottom plate body 411 can be processed from a suitable metal material (such as stainless steel, etc.) to have good mechanical properties. A generally circular perforation 412 is formed in the middle of the bottom plate body 411. The perforation 412 can mate with a corresponding through hole (not shown in the figure) at a predetermined installation position (not shown in the figure), so that the refrigerant tube 14 and the wire harness 13 arranged in the sealed tube 20 can sequentially pass through the perforation 412 and the through hole, and then be connected to other functional components of the air conditioner 1. The predetermined installation position includes but is not limited to the housing of the air conditioner 1, walls, partitions, etc. In one or more embodiments, a sealing ring 44 is provided on the perforation 412, and the refrigerant tube 14 and the wire harness 13 of the air conditioner 1 can pass through the sealing ring 44 and extend through the through hole. The setting of the sealing ring 44 can improve the airtightness at the through hole and prevent external air from entering the cavity 23 of the sealed tube 20 from the connection gap. In one or more embodiments, three bottom plate mounting holes (not shown in the figure) are also provided on the bottom plate 41 at intervals. Each bottom plate mounting hole mates with a corresponding housing mounting hole 4251 on the housing 42, so that the housing 42 and the bottom plate 41 can be conveniently fixed to the predetermined installation position by fasteners. Fasteners include but are not limited to screws, bolts, etc.

[0078] Continuing to refer to Figure 10 and Figure 11 , the housing 42 includes a housing body 421 and a circumferential flange 425. The housing body 421 and the circumferential flange 425 can be machined from a suitable metal material (such as stainless steel, etc.). Based on Figure 10 the orientation shown, the housing body 421 has a semi-closed structure with an opening facing backward. A connecting wall 422 extending vertically inward is formed on one side of the housing body 421 near the opening. The connecting wall 422 has a generally U-shaped shape so as to abut against the circumferential connecting wall 221 of the second clamping portion 22b, so that the housing 42 and the circumferential connecting wall 221 have a large contact area. In addition, the setting of the connecting wall 422 can also form a second clamping cavity 424 that mates with the clamping protrusion 222 of the second clamping portion 22b at the connection between the connecting wall 422 and the housing body 421, so that the sealed tube 20 can be conveniently clamped into the sealed tube cover 40. In addition, an extension wall 423 extending vertically outward is further formed on the side of the connecting wall 422 away from the housing body 421, so as to enclose a space that can accommodate a larger sealed tube body 21.

[0079] Continuing to refer to Figure 10 and Figure 11, the circumferential flange 425 is configured to extend vertically outward along the circumferential edge of the housing body 421. The circumferential flange 425 can abut against the bottom plate 41 to form a fixed connection with the bottom plate 41. In one or more embodiments, three housing mounting holes 4251 spaced from each other are provided on the circumferential flange 425. Each housing mounting hole 4251 is opposite to the corresponding bottom plate mounting hole on the bottom plate 41, so that the housing 42 and the bottom plate 41 can be conveniently fixed at the predetermined mounting position by fasteners. Alternatively, the housing mounting holes 4251 can also be set to other suitable numbers more or less than three, as long as they can match the bottom plate mounting holes.

[0080] As Figure 9 shown, when the seal tube pressing plate 30 of the seal tube assembly 2 of the present invention is assembled with the seal tube 20, first, the seal tube 20 is sleeved on the terminal block 12 of the air conditioner 1, so that the refrigerant tube 14 constrained on the terminal block 12 extends into the cavity 23 from the first end 20a of the seal tube 20. Specifically, the first clamping portion 22a of the seal tube 20 is sleeved on the limiting wall 1212 and the limiting member 1222 of the terminal block 12. At this time, the inner wall 223 of the circumferential connection wall 221 of the first clamping portion 22a abuts against the limiting wall 1212 and the limiting member 1222. The first refrigerant tube 141 and the second refrigerant tube 142 arranged on the first refrigerant tube limiting groove 12223 and the second refrigerant tube limiting groove 12224 of the limiting member 1222 are inserted into the cavity 23 from the first end 20a. In one or more embodiments, the wire harness 13 constrained on the terminal block 12 is also inserted into the cavity 23 from the first end 20a. That is, the first refrigerant tube 141, the second refrigerant tube 142, the power line 131, and the signal line 132 are all covered by the seal tube 20, thereby improving the utilization rate of the seal tube 20.

[0081] Continue to refer to Figure 9, after the sealing tube 20 is sleeved on the terminal block 12, then the sealing tube pressing plate 30 is pressed against the first end 20a of the sealing tube 20 and the sealing tube pressing plate 30 is fixed on the terminal block 12. Specifically, the connecting bracket 31 of the sealing tube pressing plate 30 abuts against the circumferential connecting wall 221 of the first clamping portion 22a. At this time, the outer wall 224 of the circumferential connecting wall 221 abuts against the inner side wall of the U-shaped body 311 of the connecting bracket 31. The first clamping cavity 321 of the sealing tube pressing plate 30 and the clamping protrusion 222 of the first clamping portion 22a form a clamping fit to prevent the sealing tube 20 from slipping off the sealing tube pressing plate 30. The first fixing hole 3311 and the positioning hole 3312 on the fixing bracket 33 are respectively matched with the first fixing column 1223 and the positioning column 1224 on the terminal block protective cover 122. The second fixing hole 3121 and the positioning port 33231 on the fixing bracket 33 are respectively matched with the second fixing column 1214 and the positioning protrusion 1213 on the terminal block base 121. Through the above settings, the sealing tube pressing plate 30 can be conveniently and firmly fixed on the terminal block 12, and further the sealing tube 20 is stably fixedly connected to the terminal block 12. In addition, the transverse plate 331 of the fixing bracket 33 abuts against the limiting member 1222 of the terminal block 12, so that the refrigerant pipe 14 is tightly clamped in the limiting cavity 34.

[0082] As Figure 11As shown, when the seal tube cover 40 of the seal tube assembly 2 of the present invention is assembled with the seal tube 20, first, the second clamping portion 22b of the seal tube 20 is clamped in the seal tube cover 40. Specifically, the outer wall 224 of the circumferential connection wall 221 of the second clamping portion 22b abuts against the inner wall of the connection wall 422 of the housing 42. The clamping protrusion 222 of the second clamping portion 22b forms a clamping fit with the second clamping cavity 424 on the housing 42 to prevent the seal tube 20 from slipping off the seal tube cover 40. Then, the refrigerant pipe 14 and the wire harness 13 arranged in the cavity 23 pass through the central hole in the sealing ring 44 and extend through the through hole at the predetermined installation position. The refrigerant pipe 14 and the wire harness 13 are then connected to other functional components of the air conditioner 1. Then, the seal tube cover 40 is fixed at the predetermined installation position by fasteners. The setting of the seal tube cover 40 can not only conveniently fix the seal tube 20, but also block the end of the seal tube 20 and the through hole at the predetermined installation position, playing a role in beautification. Therefore, for the seal tube assembly 2 of the present invention used in the air conditioner 1, only the refrigerant pipe 14 needs to be inserted into the seal tube 20, and the seal tube 20 can be fixed by using the seal tube pressing plate 30 and the seal tube cover 40 to achieve the sealing and protection of the refrigerant pipe 14. Compared with the traditional insulation pipe, the seal tube assembly 2 of the present invention is simple to operate and avoids the operation of wrapping and threading the slender refrigerant pipe 14. In addition, the seal tube assembly 2 of the present invention can insert two or more refrigerant pipes 14 together into the seal tube 20 without performing the wrapping operation for each refrigerant pipe 14, greatly improving the assembly efficiency. Further, the wire harness 13 constrained on the terminal block 12 can be inserted into the seal tube 20 together with the refrigerant pipe 14 without performing the wrapping operation for the wire harness 13 again, which can improve the utilization rate of the seal tube 20 and further improve the assembly efficiency.

[0083] In one or more embodiments, the present invention further provides a recreational vehicle (not shown in the figure). The recreational vehicle includes the air conditioner 1 of any of the above embodiments. The air conditioner 1 can be a split air conditioner or an integrated air conditioner. The air conditioner 1 can be arranged on the roof of the recreational vehicle, the back of the recreational vehicle or other suitable positions.
