Description

Technical Field

[0001] The invention relates to the field of air conditioners, and in particular to a protective plate and a wall-mounted air conditioner. Background Art

[0002] Large wall-mounted split air conditioners have been favored by many customers in recent years. The shell of a large wall-mounted split (2HP / 3HP) is larger than that of an ordinary 1HP or 1.5HP wall-mounted air conditioner. The size of the wall-mounted air conditioner is also relatively large, resulting in a smaller distance between the pipes on the wall-mounted air conditioner and the surrounding parts above. When the air conditioner is transported or carried, if it is subjected to external force, the pipes on the right side of the wall-mounted air conditioner will collide with the surrounding parts. Because the copper pipe is soft, it will usually be dented after being hit. As a result, when the whole machine is running, the refrigerant will pass through the copper pipe of the wall-mounted air conditioner. When the copper pipe is dented, liquid flow noise will occur. In severe cases, the copper pipe will crack and leak, causing the refrigerant in the pipe to leak, resulting in the air conditioner not cooling. Summary of the invention

[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, the preferred embodiments of the present invention are described in detail.

[0028] Reference Figures 1 to 6 , which shows an embodiment of the protective plate and the wall-mounted air conditioner of the present invention. The protective plate comprises a main body 1, one end of the main body 1 is fixedly connected to one side of the evaporator 2, the other end extends toward the direction of the pipe 22 of the evaporator 2, the top end of the main body 1 extends to the top of the pipe 22 of the evaporator 2, and the back side of the main body 1 is provided with a clamping portion 11, and the clamping portion 11 is clamped with the pipe 22 of the evaporator 2.

[0029] Specifically, wall-mounted large split air conditioners have been favored by many customers in recent years due to their excellent cooling effect and space-saving design, especially 2-HP or 3-HP large split models. Compared with ordinary 1-HP and 1.5-HP wall-mounted air conditioners, they have not only significantly improved their cooling capacity, but also have a more elegant and luxurious design. However, there are also some design challenges. Since the shell of the wall-mounted large split air conditioner is relatively large, this leads to an increase in its size, especially the pipe part of the wall-mounted air conditioner. Due to space limitations, the distance between them and the surrounding parts above becomes relatively small. This problem is particularly prominent during transportation and handling. Since the wall-mounted air conditioner is large in overall size and heavy in weight, once it is impacted or squeezed by external force, it is easy for the right side of the pipe to collide with the surrounding parts. The copper tube is an important refrigerant transmission pipeline in the air conditioner. Its material is relatively soft, which makes it more likely to be damaged in a collision. Once the copper tube is collided, it often has the problem of dents. This dent not only affects the appearance of the copper tube, but more importantly, it also affects the flow of refrigerant inside the copper tube. When the refrigerant flows in the copper tube, if it hits the concave part, liquid flow noise will be generated. This noise will not only affect the user experience, but also have a certain impact on the overall performance of the air conditioner. What's more serious is that if the copper tube cracks and leaks in the collision, the refrigerant in the pipeline will leak out. The refrigerant is the key substance for refrigeration in the air conditioner. Once it leaks, the air conditioner will not be able to cool normally, which will not only seriously affect the user experience, but also have a certain impact on the overall life of the air conditioner.

[0030] Therefore, the present application provides a protective plate, which is used to be installed on the pipeline on the right side of the evaporator 2, and is located between the pipeline of the evaporator 2 and the surrounding parts, so as to solve the problem that when the air conditioner is impacted or squeezed by external force during handling or transportation, the pipeline collides with surrounding parts and is flattened.

[0031] The protective plate includes a main body 1, which is fixedly arranged on one side of the evaporator 2, one end of the main body 1 is fixedly connected to one side of the evaporator 2, and the other end of the main body 1 is extended in the direction of the pipe 22 of the evaporator 2, so as to block one side of the pipe 22 and protect one side of the pipe 22; and the top end of the main body 1 extends to the top of the pipe 22 of the evaporator 2, so as to block the top of the pipe 22 to protect the top of the pipe 22. Therefore, the main body 1 protects one side and the top side of the pipe 22 to prevent the pipe 22 from being deformed when the air conditioner is bumped; at the same time, a clamping portion 11 is also provided on the back side of the main body 1, and the clamping portion 11 is clamped with the pipe 22 of the evaporating tube, so as to further fix the main body 1 to the evaporator 2.

[0032] The present application fixes the protective plate on one side of the evaporator 2, and protects one side and the top of the pipe 22 of the evaporator 2 through the main body 1 of the protective plate. When the air conditioner is bumped, one side and the top of the pipe 22 of the evaporator 2 are protected by the main body 1, avoiding the pipe 22 from colliding with surrounding parts, and preventing the pipe 22 from being damaged, deformed or leaking in the collision, thereby ensuring the normal operation of the air conditioner and avoiding noise.

[0033] More specifically, since the protective plate is installed on the pipeline of the evaporator 2 to protect the pipeline, a lot of condensed water will be generated on the surface of the pipeline of the evaporator 2 in the cooling mode. The protective plate is in contact with the condensed water for a long time and is in a humid environment. Therefore, the protective plate is made of ABS-121H plastic raw material, wherein the ABS-121H plastic is a thermoplastic plastic with excellent performance, and its full name is acrylonitrile-butadiene-styrene copolymer. This material has good mechanical properties, high tensile strength, and can withstand greater forces and pressures; it also has high rigidity, making the product more sturdy and durable. Moreover, its heat resistance and impact resistance are also excellent, and it can maintain stable performance even in harsh environments; that is, the main body 1 is made of ABS-121H plastic raw material, the injection molding material has good stability, and is not prone to rust and corrosion.

[0034] In one embodiment, referring to Figures 1 to 5 As shown, the clamping parts 11 are provided with a plurality of them, and the plurality of clamping parts 11 are arranged at intervals along the length direction of the main body 1, and one of the clamping parts 11 is correspondingly clamped with one of the pipes 22. Specifically, the main body 1 is provided with a plurality of clamping parts 11, and the clamping parts 11 are clamped with the pipes 22, so as to fix the main body 1 and the pipes 22, so as to prevent the main body 1 from shaking; the plurality of clamping parts 11 are arranged at intervals along the length direction of the main body 1, and one of the clamping parts 11 is correspondingly clamped with one of the pipes 22, so as to clamp the plurality of pipes 22 respectively and correspondingly on the plurality of clamping parts 11, and the plurality of clamping parts 11 limit the plurality of pipes 22 at the designated positions, so as to prevent the plurality of pipes 22 from colliding with each other when being subjected to force, so as to further protect the pipes 22, avoid the collision between the pipes 22, and prevent the pipes 22 from being damaged, deformed or leaking in the collision, so as to ensure the normal operation of the air conditioner and avoid noise.

[0035] More specifically, in this embodiment, two clamping parts 11 are provided, and the two clamping parts 11 are arranged at intervals on the back side of the main body 1, and the two clamping parts 11 are arranged along the length direction of the main body 1. The two clamping parts 11 respectively clamp the two pipes 22, thereby improving the degree of fixation between the main body 1 and the pipes 22, and the two pipes 22 are respectively limited in the two clamping parts 11 to avoid the two pipes 22 from colliding with each other, so as to cause the two pipes 22 to deform or leak.

[0036] In a specific embodiment, refer to Figures 1 to 5 As shown, the clamping portion 11 includes a clamping slot 111 , which is formed by an end of the clamping portion 11 away from the main body 1 being recessed inward, and the distance between the two ends of the clamping slot 111 is smaller than the diameter of the center of the clamping slot 111 . Specifically, the clamping portion 11 is used to clamp the pipe 22, and the clamping portion 11 includes a clamping groove 111, and the clamping groove 111 is used to accommodate the pipe 22, that is, the pipe 22 is embedded in the clamping groove 111 and clamped with the clamping groove 111; since the pipe 22 is a circular structure, the clamping groove 111 of the clamping portion 11 is also set to a circular structure, and the clamping groove 111 is formed by the end of the clamping portion 11 away from the main body 1 being recessed toward the main body 1, and the distance between the two ends of the notch of the clamping groove 111 is smaller than the diameter of the center of the clamping groove 111, that is, the size of the notch of the clamping groove 111 is smaller than the size of the longest diameter in the clamping groove 111, and the pipe 22 passes through the notch into the inside of the clamping groove 111, so that the pipe 22 is better clamped in the clamping groove 111, thereby improving the fixity of the main body 1 and the pipe 22.

[0037] More specifically, the clamping portion 11 is a claw structure, and the size of the clamping groove 111 matches the size of the pipe 22 to ensure that it can be clamped and installed without loosening after assembly, and cannot interfere with the pipe 22 during the assembly process to flatten the pipe 22. In this embodiment, two clamping portions 11 are provided, and the spacing between the two clamping portions 11 is determined according to the spacing of the pipes 22 below, and the claw of each clamping portion 11 is clamped on one of the pipes 22.

[0038] In one embodiment, referring to Figures 1 to 5As shown, the two ends of the clamping portion 11 are respectively extended from the two ends of the notch in the opposite direction in the direction away from the main body 1. Specifically, the clamping portion 11 is a claw structure, and the clamping portion 11 is extended from the two ends of the notch in the direction away from the main body 1, and the extension direction is obliquely outward, that is, the two ends of the clamping portion 11 are respectively extended from the two ends of the notch in the opposite direction in the direction away from the main body 1, and the two ends of the clamping portion 11 located on the side of the notch away from the main body 1 are designed as an "eight"-shaped structure, so that when the pipe 22 is installed in the clamping slot 111, it is easy to clamp it in place, thereby improving assembly efficiency.

[0039] More specifically, the thickness of the clamping portion 11 needs to ensure that after the pipe 22 is clamped, the clamping portion 11 will not turn white or break.

[0040] In a specific embodiment, refer to Figures 1 to 4 As shown, the back side of the main body 1 is also provided with a plurality of reinforcing ribs 12, and the plurality of reinforcing ribs 12 are arranged at intervals along the length direction of the main body 1. Specifically, the back side of the main body 1 is also provided with a plurality of reinforcing ribs 12, and the reinforcing ribs 12 are used to strengthen the structural strength of the main body 1. The reinforcing ribs 12 protrude outward from the back side of the main body 1, and are arranged to protrude upward from the back side of the main body 1. The reinforcing ribs 12 extend along the width direction of the main body 1, and the plurality of reinforcing ribs 12 are arranged at intervals along the length direction of the main body 1. The plurality of reinforcing ribs 12 increase the overall structural strength of the main body 1, and prevent the main body 1 from breaking during assembly or when subjected to force.

[0041] More specifically, the plurality of reinforcing ribs 12 are disposed at free positions on the back side of the main body 1 , and after the main body 1 , the evaporator 2 , and the pipe 22 are installed, the reinforcing ribs 12 do not interfere with surrounding parts.

[0042] In one embodiment, referring to Figures 1 to 5 As shown, the main body 1 is further provided with a shielding portion 13, which is extended obliquely upward from the top of the main body 1 in a direction away from the main body 1, and is used to protect the top of the pipe 22. Specifically, the main body 1 is further provided with a shielding portion 13, which is extended obliquely upward from the top of the main body 1 in a direction away from the main body 1, that is, the shielding portion 13 is bent from the top of the main body 1 and extends in the direction of the pipe 22, and the shielding portion 13 is located above the pipe 22, so that the main body 1 forms a baffle structure above the pipe 22 to protect the top of the pipe 22, thereby preventing the pipe 22 from colliding and deforming with surrounding parts; and the structure of the main body 1 and the shielding portion 13 fits the structure of the evaporator 2, so that the protective plate can be tightly fixed on the evaporator 2 to improve the protective effect.

[0043] In particular, there is no specific requirement for the inclination angle of the shielding portion 13 , as long as it does not interfere with the pipe 22 below and can protect the pipe 22 .

[0044] More specifically, a groove 17 is provided at the bending portion of the shielding portion 13 . The groove 17 is formed by the front side of the shielding portion 13 being recessed inwardly. The groove 17 is used to improve the structural strength of the shielding portion 13 .

[0045] In a specific embodiment, refer to Figures 1 to 6 As shown, the main body 1 is further provided with a fixing portion 14, the fixing portion 14 extends outward from one side of the main body 1, and the fixing portion 14 is fixedly connected to the side plate 21 of the evaporator 2. Specifically, the fixing portion 14 is provided on one side of the main body 1, and is extended from one side of the main body 1 toward a direction away from the side of the main body 1, and the fixing portion 14 and the main body 1 are in the same plane, and the fixing portion 14 is used to be fixedly connected to the evaporator 2, so as to fix the main body 1 on the evaporator 2, and more specifically, the fixing portion 14 is fixedly connected to the side plate 21 of the evaporator 2, so as not to affect the protective effect of the main body 1 on the pipe 22, and improve the structural stability of the main body 1.

[0046] More specifically, the fixing portion 14 is provided with a through hole 141, and the protective plate further includes a screw, one end of which passes through the through hole 141 and is locked and fixed to the side plate 21 of the evaporator 2, so the fixing method of the main body 1 and the evaporator 2 is simple and the assembly is fast. Specifically, a through hole 141 is designed at the upper end of the part where the fixing portion 14 and the side plate 21 of the evaporator 2 are in contact, and a self-tapping screw is used to fix the protective plate to the side plate 21 of the evaporator 2 so that it will not fall out or fall off after being hit.

[0047] More specifically, the width of the fixing portion 14 is the same as the width of the side plate 21 of the evaporator 2, thereby increasing the fitting area between the fixing portion 14 and the side plate 21 of the evaporator 2 and improving the degree of fixation between the main body 1 and the evaporator 2; at the same time, the length of the fixing portion 14 is not less than 10 mm, and can be adjusted according to the actual assembly position structure. The longer the length is, the larger the contact area between the protective plate and the side plate 21 of the evaporator 2 is, the better the fixing effect is, and it does not interfere with the nearby ground screws.

[0048] In one embodiment, referring to Figure 1 and Figure 6As shown, the front of the main body 1 is provided with a plurality of ribs 15, the ribs 15 are extended along the width direction of the main body 1, and the plurality of ribs 15 are arranged at intervals along the length direction of the main body 1. Specifically, the front of the main body 1 is provided with a plurality of ribs 15, the ribs 15 are extended along the width direction of the main body 1, that is, the ribs 15 are a transverse structure, and the plurality of ribs 15 are arranged at intervals along the length direction of the main body 1, so that the front of the main body 1 is evenly provided with a plurality of ribs 15, so as to enhance the stability of the structure of the protective plate, prevent deformation, and prevent rupture after being impacted by external force.

[0049] In a specific embodiment, refer to Figure 1 and Figure 4 , Figure 6 As shown, a recessed portion 16 is provided at the corner of the bottom end of the main body 1 on the side away from the side plate 21 of the evaporator 2, and the recessed portion 16 is used to reduce costs. Specifically, the main body 1 of the protective plate is the main protective part, and the length and width of the main body 1 are determined according to the right side pipe 22 of the evaporator 2. It is necessary to cover the pipe 22 at the upper right end of the evaporator 2 that is easily collided with surrounding parts after the machine is dropped. The structure of the main body 1 can be adjusted according to the direction of the pipe 22; in order to reduce the production cost of the protective plate, a recessed portion 16 is also provided at the bottom end of the main body 1. The recessed portion 16 is located at the corner of the side plate 21 of the main body 1 away from the evaporator 2, and is formed by the inward depression of the corner of the side plate 21 of the main body 1 away from the evaporator 2, so as to reduce the material used for the main body 1 and reduce the production cost.

[0050] For example, the lower right corner below the main body 1 is designed to be an inclined surface, because there is no pipeline that needs to be protected below, mainly for cost considerations to avoid waste.

[0051] Reference Figures 5 and 6 As shown, this embodiment also provides a wall-mounted air conditioner, which includes an evaporator 2 and a protective plate. The evaporator 2 includes a side plate 21. The protective plate can adopt any one of the protective plates provided by the present invention. Since the previous specification has already made a detailed introduction to the specific structure and working principle of the protective plate, for the sake of brevity of the specification, it will not be repeated here. The protective plate is fixedly connected to the side plate 21.

[0052] Exemplarily, when assembling the protective plate to the evaporator 2, first align the clamping portion 11 of the protective plate with the pipe 22 of the evaporator 2, and clamp the protective plate onto the pipe 22 from top to bottom; after the clamping portion 11 is assembled in place, use a self-tapping screw to fix the protective plate to the side plate 21 of the evaporator 2.

[0053] The wall-mounted air conditioner in this embodiment adopts the protective plate provided by the present invention, and the protective plate can protect the pipe 22 of the evaporator 2 to prevent the wall-mounted air conditioner from being flattened and cracked due to external force during handling or transportation, thereby ensuring the normal operation of the wall-mounted air conditioner and avoiding noise.

[0054] The above is only a specific embodiment of the present invention, but the protection scope of the present invention 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 present invention, and these modifications or replacements should be included in the protection scope of the present invention.
