Description

Technical Field

[0001] The present invention relates to a defrosting device for an air conditioner outdoor unit, in particular to a defrosting device for an air conditioner outdoor unit in a machine room, which is applied to the field of defrosting air conditioner outdoor units. Background Art

[0002] When an air conditioner's outdoor unit operates in heating mode, the water vapor in the air forms frost on its surface because the outdoor unit's heat exchanger is at a lower temperature than the ambient temperature. If not defrosted promptly, the frost layer will grow thicker, hindering heat exchange and causing the air conditioner's heating efficiency to decrease or even shut down for protection. Defrost is usually performed in conjunction with reverse cycle heating.

[0003] Chinese invention patent CN115164286A discloses a defrosting assembly for the heat dissipation copper tube of an air conditioner outdoor unit, which solves the problem that when thick frost forms on the surface of the heat dissipation copper tube, the air conditioner needs to spend a long time to defrost, thereby affecting the efficiency of the air conditioner.

[0004] Chinese invention patent CN118998854B discloses an air conditioner outdoor unit defrosting assembly and its use method. Through the coordinated use of various components, the frost condensed on the surface of the condenser tube can be evenly heated and melted to ensure that the air conditioner can heat normally.

[0005] Existing air conditioner outdoor unit defrosting equipment uses a mobile heating device to adhere to the surface of the condenser to perform defrosting operations. Not only is the movement speed slow, but due to the limited effective area of ​​the heating plate and the condenser, the surface of the condenser cannot be fully defrosted, resulting in limited defrosting efficiency and quality. Summary of the Invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to achieve an efficient and comprehensive defrosting operation.

[0007] To solve the above problems, the present invention provides a defrosting device for an outdoor unit of a computer room air conditioner, comprising an outdoor unit housing, a ventilation pipe, an air pump, and a condenser pipe installed inside the outdoor unit housing, and a defrosting assembly installed inside the outdoor unit housing, the defrosting assembly comprising a U-shaped deformable pipe assembly, and electric heating plates installed on the inner wall of the deformable pipe assembly and the surface of the ventilation pipe;

[0013] As a further improvement of the present application, one end of the deformable pipe assembly is located below the bottom of the condenser in the initial state, and the center of the deformable pipe assembly in the initial state is located below the center position of the condenser. After the deformable pipe assembly rotates with the cooperation of the mobilization assembly, it surrounds the outer surface of the condenser.

[0014] As a further improvement of the present application, a defrost joint control system is also included, which includes a displacement detection module, an inward closing module and a supplementary defrost module, wherein the displacement detection module includes a displacement sensor installed on the lifting platform, which is used to detect the displacement state of the deformed pipe assembly, the inward closing module is connected to the drive motor signal, and is used to control the deformed pipe assembly to retract inward so as to move downward, and the supplementary defrost module is connected to the drive motor signal, and is used to control the deformation pipe assembly to flip over and perform supplementary defrosting on the surface of the condenser.

[0033] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0034] The first implementation method:

[0035] Figures 1-4 The present invention shows a defrosting device for an outdoor unit of a computer room air conditioner, comprising an outdoor housing 1, a ventilation pipe 5, an air pump and a condenser pipe 2 installed inside the outdoor housing 1, a defrosting assembly installed inside the outdoor housing 1, the defrosting assembly comprising a U-shaped deformed pipe assembly 9, and electric heating plates 10 are installed on the inner wall of the deformed pipe assembly 9 and the surface of the ventilation pipe 5 (at Figure 4 and Figure 3 In order to facilitate viewing the connection between the first gear 6 and the rack, the lifting platform 8 is not drawn);

[0036] The defrost assembly also includes an electric guide rail 4 for driving the lifting platform 8 to move up and down. A driving motor 3 and a No. 1 gear 6 connected to its output end are installed on the lifting platform 8. The No. 1 gear 6 is engaged with a No. 1 rack 72, a No. 2 rack 73 and a No. 3 rack 74 sliding on the lifting platform 8. The tail ends of the No. 1 rack 72, the No. 2 rack 73 and the No. 3 rack 74 are all connected to the three rigid tubes of the deformable pipe assembly 9 through a bridge plate 7. A mobilization assembly 11 for adjusting the defrost area of ​​the deformable pipe assembly 9 is installed on the bridge plate 7. Before adjusting the defrost position, the deformable pipe assembly 9 is retracted inward by the driving motor 3.

[0037] Figure 6 It is shown that in the initial state, one end of the deformable pipe assembly 9 is located below the bottom of the condenser 2, and the center of the deformable pipe assembly 9 in the initial state is located below the center position of the condenser 2. After the deformable pipe assembly 9 rotates with the cooperation of the mobilization assembly 11, it surrounds the outer surface of the condenser 2.

[0038] Specifically, when performing the corresponding defrosting operation, the vertical distance between the upper and lower condenser tubes 2 provides space for the placement of the deformable pipe assembly 9, and because there is a gap between one end of the deformable pipe assembly 9 and the bottom of the condenser tube 2 in the initial state, when the deformable pipe assembly 9 is folded in, it can pass through the condenser tube 2 smoothly without obstruction.

[0039] Figure 9 It is shown that before adjusting the defrost position, an inward folding and storage operation is required to allow the deformed pipe assembly 9 to move downward smoothly. During the inward folding and storage, the three pipes No. 1 901, No. 3 903 and No. 5 905 are all folded inward (wherein the height of the No. 2 rack 73 is higher than the other two racks, so the height of the tail end of the bridge plate 7 connected to the No. 2 rack 73 needs to be adjusted so that the heights of the tail ends of the three bridge plates 7 are all on the same plane). Under the action of the support plate 71, the No. 2 pipe 902 and the No. 4 pipe 904 made of elastic material will be driven to move inward synchronously and deform accordingly. Even if there is a change in height after deformation, because the lower end is close to the inner wall of the external machine casing 1, after the height change occurs, it will not be blocked by the surface of the condenser tube 2, and the inward folding and storage can be achieved smoothly.

[0040] After the inner folding is completed, the deformable pipe assembly 9 slides down along the electric guide rail 4 to the position below the next condenser tube 2, and then the reverse operation of the inner folding operation is performed to restore the deformable pipe assembly 9 to its initial state for the next round of defrosting operation. Compared with the gradual movement of the existing technology, the defrosting efficiency is greatly improved.

[0041] The ventilation pipe 5 is connected to the air pump through a pipeline, and an air outlet is provided on the surface of the ventilation pipe 5, and the air outlet faces the arc-shaped connecting portion of the condenser pipe 2 in the vertical direction.

[0042] Specifically, during defrosting, the inner wall surface of the deformed pipe assembly 9 can perform thermal defrosting operations on the surface of the condenser tube 2 in the horizontal direction. In the vertical direction, there is an arc-shaped turning part (hereinafter referred to as the vertical area) between two adjacent condenser tubes 2, and the hot air discharged from the surface of the ventilation pipe 5 can realize the defrosting operation.

[0043] Figure 5-Figure 7 It is shown that the mobilization component 11 includes an arc-shaped recess 1104 arranged on the surface of pipe No. 1 901, pipe No. 3 903 and pipe No. 5 905, and an outer ring gear 1101 is embedded in the interior of the arc-shaped recess 1104. A bracket is installed on the top surface of the bridge plate 7, and a driving gear 1102 meshing with the outer ring gear 1101 is rotatably installed on the surface of the bracket. A driving motor 1103 is installed on the surface of the bracket, and the output end of the driving motor 1103 is connected to the end of the driving gear 1102.

[0044] Specifically, after the deformable pipe assembly 9 defrosts the lower part of the condenser tube 2, when adjusting the defrost area of ​​the deformable pipe assembly 9, it is necessary to start the mobilization assembly 11 to perform a supplementary defrost operation on the upper part of the condenser tube 2. It is necessary to start the drive motor 1103 first to drive the active gear 1102 to rotate, and then drive the outer gear ring 1101 and the No. 1 pipe 901 (taking the No. 1 pipe 901 as an example, the principles of the No. 3 pipe 903 and the No. 5 pipe 905 are the same) to rotate under the meshing action. During the rotation, the upper surface of the condenser tube 2 can be supplemented with a defrost operation (because after the rotation, the coverage area of ​​the No. 1 pipe 901 can still surround the surface of the condenser tube 2, and the difference in arc length makes the defrost area formed after the rotation larger than the surface area of ​​the condenser tube 2, such as Figure 10 shown).

[0045] When pipe No. 1 901 and pipe No. 3 903 are flipped, the middle connected pipe No. 2 902 will drive pipe No. 2 to flip synchronously because its two ends are connected to the ends of pipe No. 1 901 and pipe No. 3 903 respectively. Similarly, pipe No. 4 904 can also be flipped synchronously (pipe No. 5 905 is arranged in a mirror image of the cross section of pipe No. 1 901, and the lower end of the cross section of pipe No. 3 903 is close to the inner wall of the external machine casing 1), thereby causing the entire deformed pipe assembly 9 to flip to the top of the condenser 2 for additional defrosting, which can improve the overall defrosting quality.

[0046] Figure 4 and Figure 8It is shown that the deformable pipe assembly 9 is composed of pipe No. 1 901, pipe No. 2 902, pipe No. 3 903, pipe No. 4 904 and pipe No. 5 905. The three rigid pipes are pipe No. 1 901, pipe No. 3 903 and pipe No. 5 905. The three bridging plates 7 are rotatably connected to the surfaces of pipe No. 1 901, pipe No. 3 903 and pipe No. 5 905 respectively. The surfaces of two bridging plates 7 are fixedly connected with support plates 71, and the tail ends of the two support plates 71 are rotatably connected to the surfaces of pipe No. 2 902 and pipe No. 4 904 respectively.

[0047] Specifically, the bridge plate 7 and the support plate 71 are rotatably connected to the surface of the deformable pipe assembly 9, providing support for the subsequent mobilization assembly 11 to drive the deformable pipe assembly 9 to flip. In addition, the connection relationship between the bridge plate 7 and the support plate 71 and the surface of the deformable pipe assembly 9 makes it possible for the deformable pipe assembly 9 to be folded inward and stored.

[0048] Pipe No. 1 901, Pipe No. 3 903 and Pipe No. 5 905 are made of rigid heat-conducting materials, Pipe No. 2 902 and Pipe No. 4 904 are made of elastic memory materials, and the inner surfaces of Pipe No. 2 902 and Pipe No. 4 904 are connected with a graphene layer through a heat-insulating film, and the arc length of the cross section of the deformable pipe assembly 9 is greater than half of the circumference.

[0049] Specifically, the electric heater 10 is not arranged on the inner surface of the second pipe 902 and the fourth pipe 904. In order to prevent the deformation of the pipe from being affected by the rigid electric heater 10, a heat-conducting graphene layer is designed. The different materials of the various parts of the deformable pipe assembly 9 allow for stable storage when the pipe is folded inward. The elastic memory material can be elastic memory rubber, which is durable and allows the second pipe 902 and the fourth pipe 904 to return to their original shape after being reset. However, the surfaces of the second pipe 902 and the fourth pipe 904 need to be installed with a thermal insulation film to reduce the adverse effects of heat on the pipes during thermal defrosting. However, the graphene layer is connected to the end of the rigid pipe to achieve heat conduction, enabling thermal defrosting operations on the surface of the condenser pipe 2.

[0050] It also includes a defrost joint control system, which includes a displacement detection module, an inward closing module and a supplementary defrost module, wherein the displacement detection module includes a displacement sensor installed on the lifting platform 8, which is used to detect the displacement state of the deformed pipe assembly 9, the inward closing module is connected to the drive motor 3 signal, and is used to control the deformed pipe assembly 9 to retract inward so as to move downward, and the supplementary defrost module is connected to the drive motor 1103 signal, and is used to control the deformed pipe assembly 9 to flip over to perform supplementary defrosting on the surface of the condenser 2.

[0051] When the electric heater 10 provides defrosting operation for the lower part of the condenser 2 by the deformable pipe assembly 9, the temperature is controlled at 100-120°C. When the electric heater 10 rotates the upper part of the condenser 2 in cooperation with the adjustment assembly 11, the temperature is controlled at 70-90°C. Because the condenser 2 has been preheated when the thermal defrosting is performed at the lower part, the temperature can be lowered when it is subsequently transferred to the upper part for thermal defrosting, which can also achieve the purpose of defrosting and reduce energy consumption.

[0052] The second implementation method:

[0053] Figure 11-12 It is shown that the bottom of the condenser 2 is connected to a drain pipe 12 arranged in the same manner as the deformable pipe assembly 9 through an elastic member 123. The bottom of the drain pipe 12 is coated with a magnetic coating 122, and the inner wall of the deformable pipe assembly 9 is coated with a magnetic layer that repels the magnetic coating 122. A counterweight layer 121 is provided at the bottom of the drain pipe 12.

[0054] Pipe No. 1 901 to Pipe No. 5 905 are arranged in a clockwise direction, and the weight of the counterweight layer 121 of each drainage pipe 12 gradually increases from the head end to the tail end of the drainage pipe 12 body.

[0055] Unlike the first embodiment, in this embodiment, the surface of the condenser tube 2 is coated with a hydrophobic coating, and the elastic member 123 is a C-shaped structure (the elastic member 123 can be made of a rubber material with good weather resistance, or other similar materials), to avoid a closed state between the condenser tube 2 and the drain pipe 12, to ensure that the liquefied water on the surface of the condenser tube 2 can drip into the interior of the drain pipe 12, and the drain pipe 12 is used to collect the liquefied water on the surface of the condenser tube 2. When the deformed pipe assembly 9 is located at the lower part of the condenser tube 2, the drain pipe 12 remains in a horizontal state due to the magnetic repulsion. After the deformed pipe assembly 9 moves to the upper part, the drain pipe 12 is in an inclined state (with the effect of its own weight and the counterweight layer 121) due to the magnetic repulsion. Figure 7 For example, when tilted, the direction of the counterweight is from the lower end of pipe No. 1 901 to the head end of the first drain pipe 12 located below pipe No. 1 901, and the end close to pipe No. 2 902 is the tail end of the drain pipe 12. Similarly, the second drain pipe 12 is arranged below pipe No. 2 902, with its head end being close to the tail end of the first drain pipe 12, and its tail end being the position where pipe No. 2 902 and pipe No. 3 903 are connected. The same applies to other drain pipes 12. The liquefied water collected in the drain pipes 12 can be discharged in a centralized manner (transferred through the lower water storage tank) to avoid freezing caused by residual water.

[0056] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
