[0039] A four-way valve pipe group of an air conditioner and an air conditioner according to the present application will be described below with reference to the drawings.

[0040] As Figures 1 to 6 shown, according to the four-way valve pipe group of the air conditioner of the first aspect embodiment of the utility model, including four-way valve 1 and connecting pipe 2.

[0041] Four-way valve 1 four ports 11 all are equipped with first positioning cooperation piece, the number of connecting pipe 2 is four groups, and every group connecting pipe 2 pipe orifice 21 all are equipped with second positioning cooperation piece, four groups connecting pipe 2 pipe orifice 21 are installed in four-way valve 1 four ports 11 respectively, and first positioning cooperation piece and second positioning cooperation piece respectively one to one correspondingly mutually cooperate.

[0042] For the four-way valve pipe group given by the utility model, four-way valve 1 is the core component of the whole pipe group, which has four ports 11, and each port 11 is equipped with a first positioning cooperation piece. The first positioning cooperation piece can be a certain form of groove or recessed part, used to cooperate with the protruding part on the connecting pipe 2 to realize positioning.

[0043] Connecting pipe 2 has four groups in total, and the pipe orifice 21 of each group of connecting pipe 2 is provided with a second positioning cooperation piece. The second positioning cooperation piece can be a kind of protrusion, used to cooperate with the groove on the four-way valve 1 to ensure the correct position of the connecting pipe 2 during installation.

[0044] Specifically, the working principle and process of the four-way valve pipe group are as follows: (1) preparation stage: four-way valve 1 is ready, and its four ports 11 have been pre-installed with first positioning cooperation pieces. (2) connecting pipe 2 preparation: four groups of connecting pipe 2 are prepared, and each group of connecting pipe 2 has a second positioning cooperation piece on the pipe orifice 21. (3) installation stage: align one port 11 of each group of connecting pipe 2 with one port 11 of four-way valve 1, at this time the second positioning cooperation piece corresponds to the first positioning cooperation piece, and positioning is realized through the cooperation of the protrusion and the groove. (4) positioning is completed: the connecting pipe 2 is correctly installed into the port 11 of the four-way valve 1, ensuring that the positions of all connecting pipes 2 are correct and accurate, avoiding subsequent assembly problems caused by welding angle deviation. (5) welding: after positioning is completed, welding is performed between the connecting pipe 2 and the four-way valve 1 to fix their positions.

[0045] In summary, this design replaces the traditional clamping tool through structural cooperation, reduces the pipe group shaking caused by external factors during welding, and increases the production efficiency and product quality consistency. At the same time, such design makes the operation more convenient, reduces the time and complexity of adjusting tooling.

[0046] In the related art, the existing air conditioner outdoor unit four-way valve pipe group welding method mainly includes manual welding and automatic welding. No matter which welding method, the welding process involves inverting the four-way valve 1 in the water container, then inserting the pipe group into the four-way valve, and positioning through a specific tool, and then welding. This welding method relies on the clamping of the tool to ensure the position accuracy of the pipe group.

[0047] For the existing pipe group welding technology, different pipe groups need to adjust the position of the tool, which is very time-consuming and complex. And in the welding process, the welding gun or electrode touching the pipe group or clamp may cause the pipe group to shake, resulting in an increase in welding error. Moreover, the existing pipe group welding clamping tool has poor reliability, which can easily cause the angle deviation of the welded pipe group, thereby affecting the overall performance and consistency of the product. In addition, due to the instability of the pipe group during welding, it may eventually cause the air conditioner to produce a large vibration and noise during use.

[0048] Therefore, in order to solve the technical defects existing in the related art, the utility model provides a four-way valve pipe group of an air conditioner, which realizes the positioning and installation of the four-way valve 1 and the connecting pipe 2 by using the first positioning fitting and the second positioning fitting. Compared with the related art, at least the following advantages are achieved.

[0049] (1) Simplify the operation process: The newly designed four-way valve pipe group no longer relies on external tools for positioning, which makes the installation of the connecting pipe 2 more simple and fast, reducing the time and labor cost required for adjusting the tool.

[0050] (2) Improve production efficiency: Since the tool no longer needs to be adjusted frequently, the assembly and welding of the connecting pipe 2 and the four-way valve 1 can be completed faster on the production line, thereby significantly improving the production efficiency.

[0051] (3) Enhance product stability: Precise positioning is achieved through structural cooperation, avoiding angle deviation caused by pipe group shaking during welding, enhancing the stability and consistency of the product.

[0052] (4) Improve product quality: Precise positioning reduces vibration and noise problems caused by welding angle deviation, thereby improving the overall performance of the air conditioner and user experience.

[0053] (5) Reduce production cost: Reduce the dependence on external tools, reduce the cost of tool maintenance, and indirectly reduce the manufacturing cost per unit product due to the improvement of production efficiency.

[0054] (6) Easy to produce and maintain: The positioning structure is simple and practical, easy to produce and maintain, and also facilitates subsequent troubleshooting and maintenance work.

[0055] In summary, the technical scheme of the utility model solves the defects existing in the traditional welding method by optimizing the positioning mode between the four-way valve 1 and the connecting pipe 2, and realizes the production goal of higher efficiency and higher quality.

[0056] As shown in Figure 1 , Figure 5 and Figure 6 indicate, according to some embodiments of the utility model, the first positioning fitting part includes a matching groove 3, and the second positioning fitting part includes a matching key 4, and the matching key 4 is shape-fitted with the matching groove 3.

[0057] In the embodiment, the first positioning fitting part is a part arranged at the port 11 of the four-way valve 1, which is specifically a matching groove 3. The design purpose of the matching groove 3 is to cooperate with the protruding part on the connecting pipe 2 to realize accurate positioning. The second positioning fitting part is a part arranged at the pipe opening 21 of the connecting pipe 2, which is specifically a matching key 4. The design purpose of the matching key 4 is to cooperate with the groove in the port 11 of the four-way valve 1 to realize accurate positioning. The matching key 4 can be smoothly inserted into the matching groove 3, thereby ensuring the accurate positioning between the connecting pipe 2 and the four-way valve 1.

[0058] In this way, through the cooperation between the protrusion and the groove, the accurate alignment of the pipe group can be realized without the traditional clamping tool, thereby improving the production efficiency and reducing the product quality problems caused by the welding angle deviation.

[0059] It should be pointed out that the structures of the two kinds of positioning fitting parts are not limited to the above forms. As long as the accurate positioning between the pipe group and the four-way valve 1 can be realized and the connecting pipe 2 can maintain the correct angle and position during the installation and welding process, any other structure that can achieve the same effect can also be adopted. For example, in addition to the combination of the groove and the protrusion, the following alternative solutions can also be considered: (1) buckle type cooperation: using buckles or locking devices to realize the connection between the pipe group and the four-way valve 1, and ensuring that the pipe group does not shift during the welding process. (2) magnetic attraction type cooperation: if the material allows, the pipe group can be temporarily fixed by magnetic force until the welding is completed. (3) threaded type cooperation: using threaded tightening to fix the pipe group, providing a more stable connection. (4) elastic deformation cooperation: using the elastic deformation characteristics of the material to fix the pipe group on the four-way valve 1 in a specific way, and then permanently fixing it by welding.

[0060] Regardless of which structure form is adopted, the key is to ensure that the connecting pipe 2 and the four-way valve 1 can be accurately aligned, and to maintain stability during the welding process to prevent deviation caused by pipe group shaking due to welding. The improved design aims to reduce the uncertainty in the traditional welding process, improve the production efficiency, and ensure the consistency of product quality.

[0061] AsFigure 1 、 Figure 5 and Figure 6 As shown, in some specific embodiments of the present invention, the mating groove 3 is arranged on the inner peripheral wall of the port 11 of the four-way valve 1, and the mating key 4 is arranged on the outer peripheral wall of the pipe mouth 21 of the connecting pipe 2. The pipe mouth 21 of the connecting pipe 2 is inserted into the port 11 of the four-way valve 1 so that the mating key 4 is mated in the mating groove 3.

[0062] As will be understood, the mating grooves 3 are provided on the inner circumferential wall of the port 11 of the four-way valve 1. These grooves are designed to receive the mating keys 4 on the connecting tube 2, ensuring precise positioning when the connecting tube 2 is connected to the four-way valve 1. The mating keys 4 are provided on the outer circumferential wall of the nozzle 21 of the connecting tube 2. These keys mate with the mating grooves 3 in the port 11 of the four-way valve 1 during insertion of the connecting tube 2 into the four-way valve 1, ensuring accurate installation of the connecting tube 2.

[0063] When the connecting pipe 2 is docked with the four-way valve 1, the pipe mouth 21 of the connecting pipe 2 will be inserted into the port 11 of the four-way valve 1. At this time, the mating key 4 on the connecting pipe 2 will cooperate with the mating groove 3 in the port 11 of the four-way valve 1, thereby achieving precise positioning. In this way, the installation between the connecting pipe 2 and the four-way valve 1 becomes simpler and does not require complex external tooling for positioning, thereby improving production efficiency. It is also easier to check the welding angle of the pipe group during the production process, ensuring the quality consistency of the product. In addition, this structural matching method also improves the stability of the welding process and reduces the error caused by the shaking of the pipe group during welding.

[0064] like Figure 3 、 Figure 5 and Figure 6 As shown, according to some embodiments of the present invention, the inner wall of the port 11 of the four-way valve 1 is recessed in a direction away from the central axis of the port 11 to form a matching groove 3, and the matching key 4 is integrally formed with the connecting pipe 2.

[0065] It can be understood that the mating key 4 is formed together with the connecting pipe 2 during the manufacturing process. Such a design ensures a tight connection between the mating key 4 and the connecting pipe 2, thereby improving the stability and reliability of the structure.

[0066] Of course, the mating key 4 can also be designed to be separated from the connecting pipe 2, and the present invention does not make any special limitation here.

[0067] like Figure 4 、 Figure 5 and Figure 6 As shown, according to some embodiments of the present invention, the mating groove 3 extends along the length direction of the port 11 and is parallel to the central axis of the port 11 , and the mating key 4 extends along the length direction of the pipe mouth 21 and is parallel to the central axis of the pipe mouth 21 .

[0068] In the embodiment, the matching groove 3 is located on the inner wall of the port 11 of the four-way valve 1, and extends along the length direction of the port 11 and is parallel to the central axis of the port 11. Such design is beneficial to ensure that the connecting pipe 2 can be positioned along the correct axis direction when being inserted into the four-way valve 1.

[0069] The matching key 4 is located on the outer wall of the pipe opening 21 of the connecting pipe 2, and also extends along the length direction of the pipe opening 21 and is parallel to the central axis of the pipe opening 21. Such design is to ensure that the connecting pipe 2 can be accurately aligned with the matching groove 3 in the port 11 of the four-way valve 1 and smoothly inserted along the central axis direction to achieve accurate positioning when being inserted into the four-way valve 1.

[0070] Such design not only simplifies the assembly process between the connecting pipe 2 and the four-way valve 1, but also improves the assembly accuracy and reduces the deviation caused by improper assembly.

[0071] According to some embodiments of the present application, the bottom of the matching key 4 forms an arc-shaped access guide end (not shown in the figure), and correspondingly, the bottom of the matching groove 3 forms an arc-shaped access guide groove (not shown in the figure), and the access guide end and the access guide groove are shape-fitted. Such design makes the matching key 4 more smoothly inserted into the matching groove 3, ensuring the convenience and accuracy during assembly.

[0072] Specifically, such arc-shaped design has the following advantages: (1) convenient assembly: the arc-shaped guide end and guide groove can guide the matching key 4 to smoothly enter the matching groove 3, and even if there is a slight angle deviation during assembly, it can be naturally corrected through the arc-shaped guide structure. (2) reduce damage: the arc-shaped design reduces the risk of damage caused by hard contact during assembly, which protects both the matching key 4 and the matching groove 3. (3) improve positioning accuracy: the arc-shaped design ensures that the matching key 4 can be tightly fitted with the matching groove 3 after being completely inserted into the matching groove 3, thereby improving the positioning accuracy between the connecting pipe 2 and the four-way valve 1. (4) shape-fitted: the arc-shaped access guide end of the matching key 4 and the arc-shaped access guide groove of the matching groove 3 are shape-fitted, and such shape matching further enhances the reliability and stability of the connection.

[0073] According to some embodiments of the present application, at least two matching grooves 3 are respectively arranged on each port 11 of the four-way valve 1, and the at least two matching grooves 3 are arranged in a circumferential direction of the port 11.

[0074] Correspondingly, at least two mating keys 4 are provided on the pipe opening 21 of each group of connecting pipes 2, and the at least two mating keys 4 are spaced apart along the circumferential direction of the pipe opening 21. The number of mating keys 4 is the same as that of mating slots 3, and their positions correspond one to one.

[0075] It is understood that each port 11 of the four-way valve 1 is provided with at least two mating grooves 3, and these mating grooves 3 are spaced apart along the circumference of the port 11. This is done to ensure that the connecting pipe 2 can be reliably positioned in multiple directions when inserted into the four-way valve 1, thereby improving positioning accuracy and stability.

[0076] Correspondingly, at least two mating keys 4 are also provided on the nozzles 21 of each set of connecting tubes 2, and these mating keys 4 are spaced apart along the circumference of the nozzles 21. The number of mating keys 4 is the same as the number of mating slots 3, and their positions correspond one-to-one, ensuring that each mating key 4 accurately fits into the corresponding mating slot 3 during assembly, achieving precise positioning.

[0077] In this way, by providing the mating keys 4 and mating slots 3 at multiple locations, the position of the connecting pipe 2 can be calibrated from different angles, thus ensuring accurate positioning. Furthermore, multi-point positioning can better resist external interference, ensuring that the connecting pipe 2 is less likely to shift or wobble during the welding process. Furthermore, during the production process, this multi-point positioning method helps maintain product consistency and reduces subsequent problems caused by welding angle deviations.

[0078] In summary, this design increases the number of positioning points and reasonably distributes these positioning points, making the connection between the connecting pipe 2 and the four-way valve 1 more reliable and stable, thereby improving product quality and production efficiency.

[0079] like Figures 1 to 4 As shown, according to some embodiments of the present invention, the first positioning fitting also includes a positioning key 5, which is arranged on the outer peripheral wall of the port 11 of the four-way valve 1 and corresponds to the position of the fitting groove 3, and the positioning key 5 has the same shape as the fitting key 4.

[0080] In this embodiment, in addition to the mating grooves 3 on the inner wall of the port 11 of the four-way valve 1 and the mating keys 4 on the outer wall of the connecting pipe 2, the first positioning fitting also includes positioning keys 5. These positioning keys 5 are provided on the outer peripheral wall of the port 11 of the four-way valve 1, and their positions correspond to the mating grooves 3 on the inner wall of the port 11 of the four-way valve 1. Furthermore, the shape of the positioning keys 5 is the same as that of the mating keys 4 on the connecting pipe 2.

[0081] Specifically, the positioning keys 5 serve to further enhance the accuracy and reliability of positioning. They not only provide multiple structural safeguards to ensure that the connecting pipes 2 can be accurately aligned with the four-way valve 1 during installation, but also ensure consistency and interchangeability of assembly through the same shape design. In this way, even if there is a slight deviation during assembly, it can be corrected by the additional positioning keys 5.

[0082] Further, by adding the design of the positioning keys 5, which are the same shape as the mating keys 4 and correspond in position, the connecting pipes 2 can be more accurately aligned with the four-way valve 1 during installation, and in addition, the design of the positioning keys 5 simplifies the assembly process, reducing the need for manual adjustment, making the assembly process more convenient. That is, the design of the positioning keys 5 further enhances the reliability of positioning between the four-way valve 1 and the connecting pipes 2, ensuring higher production efficiency and better product quality.

[0084] As shown in Figures 1 to 4 , the four ports 11 of the four-way valve 1 are each provided with a first positioning fitting, and the four ports 11 of the four-way valve 1 are respectively connected to four groups of connecting pipes 2, wherein the pipe opening 21 of each group of connecting pipes 2 is provided with a second positioning fitting, and the first positioning fitting and the second positioning fitting correspond to each other one by one.

[0085] As shown in Figure 5 and Figure 6 , the number of connecting pipes 2 of the air conditioner is four groups, and the pipe opening 21 of each group of connecting pipes 2 is provided with a second positioning fitting, and the pipe opening 21 of the four groups of connecting pipes 2 is respectively installed in the four ports 11 of the four-way valve 1, wherein the four ports 11 of the four-way valve 1 are each provided with a first positioning fitting, and the first positioning fitting and the second positioning fitting correspond to each other one by one.
