Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a protective device and an air conditioner outdoor unit. Background Art

[0002] The evaporator is equipped with two adjacent pipes, which are connected by an elbow to form a flow channel to ensure that the refrigerant can circulate smoothly throughout the air conditioning system. This elbow is usually designed on one side of the evaporator, and the evaporator is installed on the bottom shell.

[0003] However, in some models, since the evaporator is designed to be long and the bottom shell is often common with other shell structures, after the evaporator is assembled, the gap between the elbow on one side of the evaporator and the bottom shell becomes very small.

[0004] When the product is packaged for transportation and handling, if the air conditioner outdoor unit is hit by external forces, there is a possibility of collision between the side of the evaporator and the bottom shell. Especially when the elbow is close to the bottom shell, the buffer space of the evaporator is very limited. Once it is subjected to external force, the elbow is easy to hit the bottom shell. Since the bottom shell is made of injection molding material with a relatively hard hardness, the elbow will be severely deformed when the two collide with each other. The deformation of the elbow will affect the operation of the refrigerant in the system, causing abnormalities such as liquid flow sound. When the deformation is serious, the refrigerant may even leak, causing the entire machine to be unable to cool or heat.

[0005] Therefore, there is an urgent need for a high-strength and high-hardness protective device to protect one side of the evaporator installation elbow to solve this problem and ensure the safety and stability of the air conditioner outdoor unit during transportation and use.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

As used in this utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0037] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0038] See also Figure 1 and Figure 2 The embodiment of the utility model provides a protective device 10, which is installed between the side of the evaporator 20 and the bottom shell 30. The evaporator 20 is installed on the bottom shell 30. The side of the evaporator 20 is provided with a heat exchange tube 21. The heat exchange tube 21 protrudes along the side of the evaporator 20 to form a plurality of vertically arranged protrusions 211 (i.e., elbows). The protective device 10 includes: a first plate 11, the first plate 11 is fixedly connected to the side of the evaporator 20, and the first plate 11 is provided with a clearance groove 111 for making way for at least one protrusion 211; a second plate 12, one side of the second plate 12 is connected to the side of the first plate 11, and the other side of the second plate 12 extends along the protruding direction of the protrusion 211, and the extension length is greater than the protruding length of the protrusion 211. In this embodiment, the bottom shell 30 is a shell connected to the side of the evaporator 20, so the bottom shell 30 can also be called a side shell. Secondly, since the first plate 11 is fixedly connected to the side of the evaporator 20, and the side of the evaporator 20 is provided with a heat exchange tube 21, the first plate 11 needs to be designed with a clearance groove 111 to make way for the heat exchange tube 21. The design of the clearance groove 111 not only ensures the close fit between the protective device 10 and the evaporator 20, but also does not interfere with the normal operation of the heat exchange tube 21.

[0039] The second plate 12 has a longer extension length, so that it can cover and support a larger area of ​​the side of the evaporator 20, and can cover all or at least part of the protrusion 211. When the extension length of the second plate 12 is long enough, it can be more firmly fixed on the side of the evaporator 20. When the air conditioner outdoor unit is hit by an external force, the second plate 12 can protect the heat exchange tube 21, further improving the protective effect of the protective device 10.

[0040] Further, such as Figure 3 As shown, the protective device 10 further includes: a third plate 13, one side of the third plate 13 is connected to the other side of the second plate 12, and the third plate 13 is opposite to the first plate 11. In this embodiment, the third plate 13 is upward (i.e., parallel to the first plate 11, combined with Figure 1 and Figure 3 The third plate 13 is a bent structure formed by the bottom shell 30. When the air conditioner outdoor unit is hit by an external force, the third plate 13 is the first to contact the tested part with the bottom shell 30, which better protects the protrusion 211. In a specific application example, the height of the third plate 13 bent upward exceeds the protrusion 211, and the protective effect can be better. Preferably, if space permits, the bending height is selected to be about 5 mm. The third plate 13 mainly plays a role in protecting the elbow, and makes the entire protective device 10 form a more stable frame structure.

[0041] In one embodiment, if Figure 1 As shown, the gap between the third plate 13 and the protrusion 211 is greater than 5 mm. In order to better protect the protrusion 211, a certain gap should be left between the third plate 13 and the protrusion 211. When the gap margin is sufficient, considering that a certain buffer margin is required when the air conditioner outdoor unit is hit, it is appropriate that the third plate 13 exceeds the end surface of the protrusion 211 by at least 5 mm.

[0042] Specifically, ensuring that the clearance margin is sufficient is to avoid damage to both the third plate 13 and the heat exchange tube 21 due to friction or collision between them during daily use. In particular, when the air conditioner outdoor unit is running, due to the influence of vibration and airflow, if the clearance is too small, friction and collision are likely to occur, thereby affecting the heat exchange efficiency of the evaporator 20.

[0043] Secondly, considering the external impact that the air conditioner outdoor unit may be subjected to during installation and use, such as collision during transportation, wind and rain in bad weather, etc., the gap between the third plate 13 and the heat exchange tube 21 needs to have a certain buffer margin. In this way, even if the air conditioner outdoor unit is subjected to a certain degree of impact, the impact force can be absorbed and dispersed through this gap, avoiding direct damage to the evaporator 20 and the third plate 13.

[0044] Therefore, after comprehensive consideration, the distance of the third plate 13 beyond the end surface of the protruding portion 211 of the heat exchange tube 21 is set to 5 mm. This value not only ensures that the clearance margin is sufficient, but also provides sufficient buffer space when impacted, ensuring the stability and durability of the air conditioner outdoor unit.

[0045] Furthermore, there is a gap between the third plate 13 and the bottom shell 30. In this embodiment, when the gap margin is sufficient, considering that a certain buffer margin is required when the air conditioner outdoor unit is hit, in order to better protect the side of the evaporator 20, a certain gap should be left between the third plate 13 and the bottom shell 30. At the same time, the gap between the third plate 13 and the bottom shell 30 is conducive to reducing friction and wear, and can also avoid deformation and damage caused by thermal expansion or contraction. When the air conditioner outdoor unit is running, due to large temperature changes, if the third plate 13 is tightly fitted with the bottom shell 30, it is easy to deform due to thermal expansion and contraction, thereby affecting the stability and reliability of the entire system.

[0046] Secondly, the existence of the gap between the third plate 13 and the bottom shell 30 also allows a certain amount of installation and adjustment space for the protective device 10. During the installation of the protective device 10, even if there is a slight error or deviation, it can be compensated by adjusting the gap to ensure that the third plate 13 can be accurately and stably located at the predetermined position. At the same time, it also provides convenience for the maintenance and replacement of the protective device 10 in the future, so that maintenance personnel can more conveniently disassemble and install the protective device 10.

[0047] In one embodiment, the first plate 11, the second plate 12 and the third plate 13 are an integrated structure, and the first plate 11 and the third plate 13 are vertically connected to both sides of the second plate 12. The design of the integrated structure of the first plate 11, the second plate 12 and the third plate 13 allows the various parts of the protective device 10 to be tightly combined, without additional connectors or interfaces, and there is no need to assemble multiple parts during the manufacturing process, which greatly simplifies the manufacturing process. At the same time, during installation, there is no need to fix each plate separately, and the entire protective device 10 only needs to be fixed to the side of the evaporator 20 at one time, thereby improving installation efficiency.

[0048] Furthermore, the protrusion 211 is an elbow structure, and the elbow structure includes a bending portion and two connecting portions connected to both sides of the bending portion. The first plate 11 is provided with at least two make way grooves 111, which are respectively used to make way for the two connecting portions. In this embodiment, the two connecting portions connected to the elbow structure are two copper tubes, so that the pipe connection of the heat exchange tube 21 is more stable. The first plate 11 is installed at the position of the two copper tubes corresponding to the elbow structure, so the two make way grooves 111 respectively make way for the two copper tubes. The size of each make way groove 111 matches the diameter of the copper tube to ensure that the first plate 11 will not collide with the copper tube after installation.

[0049] Further, such as Figure 2As shown, a through hole 112 is provided on the first plate 11, and a detachable connector is installed on the side of the first plate 11 and the evaporator 20 on the through hole 112. In this embodiment, the first through hole 112 can be a screw hole. Preferably, a screw hole is designed in the blank area on the left and right sides of the first plate 11, that is, on one side next to the two clearance grooves 111, and the screw hole is designed in the middle of the blank area as much as possible, so that it is convenient to fix the screw without interfering with the surrounding copper tubes, and it can also effectively avoid damaging the copper tubes when screwing.

[0050] Further, such as Figure 4 As shown, a rib strip 121 is provided in the middle area of ​​the second plate 12. In this embodiment, the rib strip 121 in the middle area of ​​the second plate 12 is a rectangular structure, and the width and length of the rib strip 121 can be determined according to the actual effect and the width and length of the second plate 12. The design of the rib strip 121 can significantly enhance the rigidity and structural stability of the second plate 12. When the air conditioner outdoor unit is subjected to external force, the rib strip 121 can effectively resist deformation and distortion, and maintain the stability and reliability of the protective device 10.

[0051] Furthermore, the material of the protective device 10 is hot-dip galvanized sheet. The protective device 10 mainly prevents the bottom shell 30 from hitting the heat exchange tube 21. Therefore, the protective device 10 needs to have a certain strength and hardness, and cannot be easily deformed. The protective device 10 is installed on the side of the evaporator 20. When the air conditioner is in the cooling mode, the indoor evaporator 20 is humid around the protective device 10, and the protective device 10 is easy to rust after contacting water. Therefore, it is preferred that the protective device 10 uses Q235A2.0X1000XC hot-dip galvanized sheet as the raw material of the protective plate. Q235A is a grade of steel, which is a common carbon structural steel widely used in the manufacture of buildings, bridges, vehicles, ships, pressure vessels, etc. Among them, "Q" represents the yield strength, "235" means the yield strength is 235MPa, and "A" represents the grade of steel, where the carbon content of grade A steel is between 0.14 and 0.22%. "2.0" represents the thickness of the plate, in millimeters. In other words, the thickness of this hot-dip galvanized sheet is 2 mm. "1000" usually represents the width of the plate, which can be in millimeters. Therefore, the width of this hot-dip galvanized sheet is 1000 mm. "XC" can represent the treatment, standard or quality grade. Hot-dip galvanized sheet is a thin steel sheet that is immersed in a molten zinc bath to adhere a layer of zinc to its surface. This galvanized steel sheet has good corrosion resistance, paintability, weldability and formability.

[0052] In this embodiment, the protective device 10 mainly protects the protrusion 211 near the bottom shell 30, so it is installed at the position of the protrusion 211 on the side of the evaporator 20. The protrusion 211 that is closer to the bottom shell 30 and has the risk of hitting the bottom shell 30 when subjected to force is installed at this protrusion 211.

[0053] In other embodiments, if there are multiple protrusions 211 on the side of the evaporator 20 along the length direction of the side of the evaporator 20, multiple protection devices 10 can be provided along the protrusions 211 from top to bottom on the side of the evaporator 20, and each protection device 10 correspondingly protects one protrusion 211. If there are multiple rows of protrusions 211 on the side of the evaporator 20 in the width direction, multiple protection devices 10 can be provided along the protrusions 211 on the side of the evaporator 20 from left to right, and each protection device 10 correspondingly protects one protrusion 211.

[0054] The embodiment of the utility model further provides an air conditioner outdoor unit, comprising an evaporator 20 and a bottom shell 30 , wherein the protective device 10 as described above is installed between the side of the evaporator 20 and the bottom shell 30 .

[0055] The utility model also provides a method for installing the protective device 10. Specifically, take the protective device 10, first align the first plate 11 with the position of the through hole 112, then take two screws, and use the screws to fix the first plate 11 on the side of the evaporator 20.

[0056] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
