[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

If the specific posture changes, the directional indications will also change accordingly.

[0043] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0044] The present invention proposes an air conditioner outdoor unit 100 for use in an air conditioner. The air conditioner includes the air conditioner outdoor unit 100 and the air conditioner indoor unit. A flexible connection component connects the air conditioner indoor unit and the air conditioner outdoor unit 100, respectively. The air conditioner can be a split-type air conditioner that is easy for users to install individually. The air conditioner uses a refrigerant pipe to connect the indoor heat exchanger of the air conditioner indoor unit and the outdoor heat exchanger 2 of the air conditioner outdoor unit 100, and refrigerant is injected into the refrigerant circuit before the equipment leaves the factory. In this way, when the user installs the equipment by themselves, they only need to fix the air conditioner indoor unit and the air conditioner outdoor unit 100 separately, without the need to assemble the refrigerant pipe and add refrigerant, thereby reducing the difficulty of installation and enabling personal installation by the user. However, the present design is not limited to this. In other embodiments, the air conditioner of the present invention can also be an ordinary split-type air conditioner or an integrated air conditioner.

[0045] See also Figures 1 to 7 In one embodiment of the present invention, the air conditioner outdoor unit 100 includes:

[0046] The casing 1, and the outdoor heat exchanger 2 and the electric heating device installed in the casing 1, the electric heating device is used to heat the outdoor heat exchanger 2 to defrost the air conditioner outdoor unit 100, and the casing 1 is configured with at least a portion close to the electric heating device as a metal material.

[0047] Specifically, in the defrost mode, the electric heating device can heat the outdoor heat exchanger 2. The electric heating device generally includes an electric heating element and a control module. The control module controls the temperature rise of the electric heating element, so that the electric heating element directly heats the outdoor heat exchanger 2. This causes the temperature inside the air-conditioning outdoor unit 100 to be too high (possibly reaching several hundred degrees). In this case, if the casing 1 of the air-conditioning outdoor unit 100 is made of plastic material, the casing 1 is prone to deformation and is difficult to adapt to the defrost mode of the air conditioner.

[0048] Therefore, the housing 1 is configured with a metal material, which can adapt to higher heating temperatures, thereby reducing the possibility of deformation of the housing 1. Metal materials also have higher weather resistance and are more adaptable to the environment. They can resist erosion by natural factors such as ultraviolet rays, temperature changes, and humidity, and can adapt to extreme weather. In addition, metal materials have higher hardness, rigidity, and corrosion resistance than plastic materials, thereby extending the service life of the air conditioner outdoor unit 100.

[0049] Furthermore, at least the portion of the housing 1 near the electric heating device is configured to be made of metal. Since the portion near the electric heating device needs to withstand a higher temperature limit, only the portion of the housing 1 near the electric heating device can be configured to be made of metal, thereby improving the local high temperature resistance of the housing 1. For example, when the electric heating device is disposed on the chassis 11, only the chassis 11 can be configured to be made of metal, or the chassis 11, front panel 12, rear panel 13, and side panels 14 can all be configured to be made of metal, while the top and side panels can be configured to be made of plastic. Alternatively, the chassis 11 can be configured to be made of metal, the top and side panels can be configured to be plastic, and the front panel 12 and / or rear panel 13 and / or side panels 14 can be divided into two parts along the upper and lower directions, with the portion of the front panel 12 and / or rear panel 13 and / or side panels 14 near the chassis 11 being made of metal, and the portion of the front panel 12 and / or rear panel 13 and / or side panels 14 near the top and side panels being made of plastic. In other embodiments, the chassis 11 , the front panel 12 , the rear panel 13 , the side panels 14 and the top and side panels are all made of metal.

[0050] In the embodiment of the present invention, the housing 1 is configured to be a sheet metal material, that is, the housing 1 is manufactured using a sheet metal process, which not only facilitates the processing of the housing 1 but also ensures the structural strength of the housing 1 .

[0051] To further extend the service life of the housing 1, in an embodiment of the present invention, a surface treatment layer is formed on the surface of the housing 1. Specifically, the surface of the housing 1 is treated to form a surface treatment layer on the surface of the housing 1 to protect the internal materials of the housing 1, thereby improving the salt spray resistance of the housing 1 and thus increasing the service life of the housing 1.

[0052] Furthermore, in an embodiment of the present invention, the process treatment layer includes an electrophoretic coating. That is, the surface of the housing 1 is subjected to electrophoretic treatment, thereby forming an electrophoretic coating on the surface of the housing 1, thereby improving the salt spray resistance of the housing 1 and also improving the surface adhesion of the housing 1, which facilitates subsequent processing of the housing 1.

[0053] Furthermore, the treatment layer also includes a protective paint layer. Specifically, the surface of the housing 1 is spray-painted to form a protective paint layer on the surface of the housing 1, isolating the housing 1 from external air and water, thereby increasing the service life of the housing 1. Furthermore, the protective paint layer can be provided in various colors according to product requirements, facilitating personalized customization of the air conditioner.

[0054] See also Figure 1 and Figure 2 In an embodiment of the present invention, the housing 1 includes a chassis 11, and the electric heating device includes an electric heating element. The electric heating element is disposed on the chassis 11 and is located below the outdoor heat exchanger 2. Specifically, the electric heating element of the electric heating device is disposed on the chassis 11 to facilitate the arrangement of the electric heating. To improve the high-temperature resistance of the chassis 11, the chassis 11 is configured as a sheet metal member. The electric heating element is located below the outdoor heat exchanger 2, thereby facilitating the heating of the outdoor heat exchanger 2 by the electric heating element.

[0055] Furthermore, the electric heating element is configured as an electric heating belt 3, which is coiled and arranged below the outdoor heat exchanger 2. Specifically, the electric heating element is configured as an electric heating belt 3, that is, the electric heating element is configured as a long strip structure with a length greater than its diameter. To facilitate the installation of the electric heating belt 3 and ensure the heating efficiency of the electric heating belt 3 on the outdoor heat exchanger 2, the electric heating belt 3 is coiled and arranged below the outdoor heat exchanger 2, that is, the outdoor heat exchanger 2 is projected downward to form a covering area. The electric heating belt 3 is coiled on the chassis 11 from the inside to the outside or from the outside to the inside, with the covering area as the boundary.

[0056] In another embodiment of the present invention, the electric heating element is configured as an electric heating tape 3, which extends back and forth on the chassis 11 and along the extension direction of the outdoor heat exchanger 2. Specifically, the electric heating tape 3 extends back and forth on the chassis 11 and along the extension direction of the outdoor heat exchanger 2. That is, the outdoor heat exchanger 2 projects downward to form a covering area, and the electric heating tape 3 extends along the length of the covering area and extends entirely along the width of the covering area. Alternatively, the electric heating tape 3 extends along the width of the covering area and extends entirely along the length of the covering area. This facilitates installation of the electric heating tape 3 while ensuring the heating efficiency of the electric heating tape 3 on the outdoor heat exchanger 2. In other embodiments, the electric heating tape 3 may also be arranged randomly on the chassis 11. That is, in this embodiment, the specific arrangement of the electric heating tape 3 on the chassis 11 is not limited. As long as it facilitates installation of the electric heating tape 3 and ensures the heating efficiency of the electric heating tape 3 on the outdoor heat exchanger 2, it is within the scope of protection of this embodiment. In other embodiments, the electric heating element may also be configured as an electric heating wire.

[0057] See also Figure 1 and Figure 7To facilitate the processing of the casing 1, in an embodiment of the present invention, the casing 1 includes a chassis 11, a front panel 12, a rear panel 13 and side panels 14. A first flange 111 extending upward is formed on the periphery of the chassis 11. The front panel 12, the rear panel 13 and the side panels 14 are all mounted on the chassis 11 through the first flange 111. The front panel 12 and the rear panel 13 both have second flanges extending toward each other, and opposite sides of the side panels 14 are respectively connected to the front panel 12 and the rear panel 13 through the second flanges.

[0058] Specifically, the housing 1 includes a chassis 11, a front panel 12, a rear panel 13, and side panels 14 that are joined together. The side panels 14 may include a left side panel, a right side panel, and a top side panel. The left side panel, the right side panel, and the top side panel may be integrally formed or separately formed. To facilitate the installation of the chassis 11 with the front panel 12, the rear panel 13, and the side panels 14, a first flange 111 extending upward is formed on the periphery of the chassis 11. The front panel 12, the rear panel 13, and the side panels 14 are all mounted to the chassis 11 via the first flange 111. The lower edges of the front panel 12, the rear panel 13, and the side panels 14 are respectively connected to the first flange 111, thereby increasing the contact area between the chassis 11 and the front panel 12, the rear panel 13, and the side panels 14, thereby facilitating assembly of the housing 1. Both the front panel 12 and the rear panel 13 are provided with a second flange, and because the front panel 12 and the rear panel 13 are placed opposite to each other, the second flanges on the front panel 12 and the rear panel 13 extend toward each other, and the opposite sides of the side panel 14 are respectively connected to the front panel 12 and the rear panel 13 through the second flange, thereby increasing the contact area between the side panel 14 and the front panel 12 and the rear panel 13, respectively, and facilitating the assembly of the casing 1.

[0059] The first flange 111 is formed by punching upward from the periphery of the chassis 11, and the second flange is formed by punching the front and rear panels 12, 13 toward each other, thereby facilitating the installation of the chassis 11, front panel 12, and rear panel 13. In other embodiments, the first flange 111 can also be provided at the lower edges of the front, rear, and side panels 14, respectively, and the second flange can also be provided on opposite sides of the side panel 14. During actual installation, the chassis 11 can be installed first, followed by the corresponding installation of the electric heating device and the outdoor heat exchanger 2 within the casing 1, and then the front and rear panels 12, 13 can be installed separately. Finally, the side panel 14 can be spliced ​​between the front and rear panels 12, 13. In other embodiments, the chassis 11 may be installed first, and then the electric heating device and the outdoor heat exchanger 2 in the casing 1 may be installed accordingly, and then the side panels 14 may be installed separately, and then the front panel 12 and the rear panel 13 may be installed, or the front panel 12 and the side panels 14 may be installed first, and then the rear panel 13 may be installed, or the rear panel 13 and the side panels 14 may be installed first, and then the front panel 12 may be installed. In this solution, there is no restriction on the order of installing the chassis 11, the front panel 12, the rear panel 13, and the side panels 14. As long as the assembly of the air conditioner outdoor unit 100 can be achieved, it is within the scope of protection of this solution. In this solution, the front panel 12, the rear panel 13, and the side panels 14 are formed separately. In other embodiments, at least two of the front panel 12, the rear panel 13, and the side panels 14 are formed integrally, or one or two of the front panel 12, the rear panel 13, and the side panels 14 are formed integrally with the chassis 11.

[0060] To further facilitate the installation of the housing 1, the front panel 12, rear panel 13, and side panels 14 are all mounted to the first flange 111 via first fasteners; opposite sides of the side panel 14 are mounted to the second flange via second fasteners. In other words, the front panel 12, rear panel 13, and side panels 14 are all mounted to the chassis 11 via first fasteners, and opposite sides of the side panel 14 are respectively mounted to the front panel 12 and rear panel 13 via second fasteners. This facilitates the disassembly and installation of the housing 1, and further facilitates the assembly and subsequent maintenance of the air conditioner outdoor unit 100, while also ensuring the installation stability of the housing 1. Of course, in other embodiments, the front panel 12, rear panel 13, and side panels 14 can also be mounted to the chassis 11 via welding or clamping, and / or opposite sides of the side panel 14 can be mounted to the front panel 12 and rear panel 13 via second fasteners. The first and second fasteners can both be configured as fastening screws.

[0061] See also Figures 1 to 7In an embodiment of the present invention, a handle portion 6 is further provided on the housing 1 to facilitate the user's installation and movement of the air conditioner outdoor unit 100. Therefore, a mounting hole is provided on the housing 1, and the handle portion 6 is directly snapped onto the periphery of the mounting hole through a snap fit, thereby facilitating the installation of the handle portion 6. In this case, the handle portion 6 can be configured as a flexible member such as rubber. In other embodiments, the handle portion 6 can also be integrally formed with the housing, that is, the periphery of the mounting hole forms a third flange for the user to hold. The handle portion 6 is generally located on the upper portion of the air conditioner outdoor unit 100. Of course, in other embodiments, the handle portion 6 can also be located on the lower portion of the air conditioner outdoor unit 100.

[0062] In the embodiments of the present invention, please refer to Figure 1 and Figure 7 The front panel 12 is provided with an air outlet 121, and an air outlet grille 15 is located at the air outlet 121. The air outlet grille 15 is mounted to the front panel 12 via a third fastener. The air outlet 121 is used to discharge air from the air conditioning outdoor unit 100. The air outlet grille 15 is located at the air outlet 121 to prevent insects and other objects from accidentally entering the interior of the air conditioning outdoor unit 100. The air outlet grille 15 is mounted to the front panel 12 via a third fastener, facilitating its installation. In this embodiment, the dimensions of the air outlet grille 15 are approximately equal to those of the front panel 12, thereby enhancing the overall appearance of the air conditioning outdoor unit 100. In other embodiments, the dimensions of the air outlet grille 15 are smaller than those of the front panel 12, such as when the air outlet grille 15 is installed within the air outlet 121. In this case, the air outlet grille 15 can be configured as a mesh cover. Alternatively, the front panel 12 may be omitted, and the entire front portion of the air conditioning outdoor unit 100 may serve as the air outlet 121, with the air outlet grille 15 mounted thereto. Wherein, the third fasteners can all be configured as fastening screws.

[0063] See also Figure 4 and Figure 7 In an embodiment of the present invention, a middle partition plate 4 is further provided in the casing 1. One side of the middle partition plate 4 is connected to the casing 1, and the other side is connected to the outdoor heat exchanger 2. Specifically, the middle partition plate 4 is used to isolate the installation space of the casing 1. One side of the middle partition plate 4 is connected to the casing 1, and the other side is connected to the outdoor heat exchanger 2, thereby separating the air conditioner outdoor unit 100 from the outdoor heat exchanger 2 and other structures. For example, the outdoor heat exchanger 2 and the electric control box are arranged on opposite sides of the middle partition plate 4, thereby reducing the possibility of condensed water entering the electric control box. Alternatively, the outdoor heat exchanger 2 and the flexible connection assembly are arranged on opposite sides of the middle partition plate 4, thereby facilitating the installation of the outdoor heat exchanger 2 and the storage of the flexible connection component.

[0064] To ensure the stability of the wind wheel installation, please refer to Figures 2 to 6In an embodiment of the present invention, the motor bracket 5 is mounted on one side of the outdoor heat exchanger 2. The lower end of the motor bracket 5 is fixed to the chassis 11, and the upper end of the motor bracket 5 is fixed to at least the front panel 12. Specifically, the motor bracket 5 is used to mount the motor and the wind rotor, and the motor drives the wind rotor to rotate. The motor bracket 5 is mounted on one side of the outdoor heat exchanger 2, and the wind rotor is also mounted on the same side of the outdoor heat exchanger 2. This increases the wind speed at the outdoor heat exchanger 2 and improves the heat exchange efficiency of the air conditioner indoor unit. The lower end of the motor bracket 5 is fixed to the chassis 11, and the upper end is fixed to at least the front panel 12. This ensures the stability of the motor bracket 5 and reduces the possibility of accidental shaking of the wind rotor during rotation. In this embodiment, the lower end of the motor bracket 5 is fastened to the chassis 11 by a fourth fastener. In other embodiments, the motor bracket 5 can also be mounted to the chassis 11 by welding, clamping, or other means. The upper end of the motor bracket 5 can be connected to the front panel 12, the fixed side panel 14, the outdoor heat exchanger 2, and so on.

[0065] Furthermore, a mounting plate 51 is provided at the upper end of the motor bracket 5. The mounting plate 51 extends toward the front panel 12 and is fixed to the front panel 12. A slot 52 is formed at the upper end of the motor bracket 5, facing the outdoor heat exchanger 2. The slot 52 engages with the edge of the outdoor heat exchanger 2. Specifically, in this embodiment, the motor bracket 5 is mounted on the side of the outdoor heat exchanger 2 facing the front panel 12. Therefore, one side of the upper end of the motor bracket 5 is provided with the mounting plate 51 extending toward the front panel 12 and is fixed to the front panel 12 via the mounting plate 51. The other side is formed with a slot 52. The slot 52 engages with the edge of the outdoor heat exchanger 2, thereby ensuring the installation stability of the motor bracket 5. In other embodiments, the motor bracket 5 can also be installed on the side of the outdoor heat exchanger 2 facing the rear panel 13, so one side of the upper end of the motor bracket 5 is provided with a mounting plate 51 extending toward the rear panel 13, and is fixed to the rear panel 13 through the mounting plate 51, and a slot 52 is formed on the other side, and the slot 52 is snapped into the edge of the outdoor heat exchanger 2.

[0066] See also Figure 8 and Figure 9 In an embodiment of the present invention, the air conditioner outdoor unit 100 includes an outdoor refrigerant pipe, which is used to communicate with the indoor refrigerant pipe of the air conditioner indoor unit. The housing 1 is provided with a mounting position 16 for installing the outdoor refrigerant pipe and / or the indoor refrigerant pipe. Specifically, the outdoor heat exchanger 2 in the air conditioner outdoor unit 100 is connected to two outdoor refrigerant pipes, and the corresponding indoor heat exchanger in the air conditioner indoor unit is connected to two indoor refrigerant pipes. The outdoor refrigerant pipes are connected to the indoor refrigerant pipes to form a refrigerant circuit. For mobile air conditioners, refrigerant is injected into the refrigerant circuit before the equipment leaves the factory. Therefore, in order to facilitate the transportation and installation of the refrigerant circuit, the housing 1 is provided with a mounting position 16 for installing the outdoor refrigerant pipe and / or the indoor refrigerant pipe.

[0067] The mounting position 16 can be configured as a through-hole in the housing 1 , which is used to pass an outdoor refrigerant pipe or an indoor refrigerant pipe. In this case, the outdoor refrigerant pipe and the indoor refrigerant pipe can be integrally formed to reduce refrigerant pipe leakage. Typically, a sealing ring 171 is provided around the periphery of the through-hole to ensure sealing.

[0068] In another embodiment of the present invention, a quick-connect connector 161 is fixed to the mounting position 16, one end of the quick-connect connector 161 is connected to the outdoor refrigerant pipe, and the other end is connected to the indoor refrigerant pipe. Specifically, the refrigerant circuit of the mobile air conditioner is injected with refrigerant before the equipment leaves the factory. At this time, the air conditioner outdoor unit 100 and the air conditioner indoor unit are often pre-connected together through the refrigerant circuit. The refrigerant circuit needs to be installed in the housing 1, which may cause inconvenience in assembly. Therefore, a quick-connect connector 161 is provided. The quick-connect connector 161 is pre-fixed to the mounting position 16, and one end of the quick-connect connector 161 is connected to the outdoor refrigerant pipe, and the other end is connected to the indoor refrigerant pipe, thereby facilitating the installation of the outdoor refrigerant pipe and / or the indoor refrigerant pipe. Moreover, if the air conditioner outdoor unit 100 is damaged during use, the air conditioner outdoor unit 100 can be directly replaced.

[0069] In order to facilitate the installation of the quick connector 161, the housing 1 also includes a reinforcing plate 162.
