[0027] 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.

[0028] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0029] 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.

[0030] The present invention provides an electric control box 100 for use with an air conditioner or other device. The air conditioner includes an outdoor unit and an indoor unit, and a flexible connection assembly connects the indoor and outdoor units, respectively. The air conditioner can be a split-type air conditioner that is easy for users to install. The flexible connection assembly typically includes a sleeve, a refrigerant pipe, a drain pipe, and connecting wires that pass through the sleeve. The refrigerant pipe connects the indoor heat exchanger of the indoor unit and the outdoor heat exchanger of the outdoor unit, and refrigerant is injected into the refrigerant circuit before the device leaves the factory. In this way, when users install the device themselves, they only need to fix the indoor and outdoor units separately, without having to assemble the refrigerant pipe and add refrigerant, thereby reducing the installation difficulty and enabling user-friendly installation.

[0031] Furthermore, the compressor of this split-type air conditioner, which is user-friendly and easy to install, can be installed inside the indoor unit, thereby reducing the weight of the outdoor unit and facilitating its installation outdoors. Accordingly, to reduce compressor noise, a noise reduction structure is required for the compressor. However, the present invention is not limited to this. In other embodiments, the air conditioner of the present invention can also be a conventional split-type air conditioner or an integrated air conditioner.

[0032] See also Figures 1 to 3 In one embodiment of the present invention, the electric control box 100 includes:

[0033] Shell 1;

[0034] A circuit board 12 is disposed in the housing 1; and

[0035] An anti-electromagnetic interference component is provided with a clamping structure between the shell 1 and the anti-electromagnetic interference component to fix the anti-electromagnetic interference component in the shell 1.

[0036] Specifically, the housing 1 is provided with a housing space for accommodating a circuit board 12, a conductive wire harness 14, and some power devices. Furthermore, because the electric control box 100 is responsible for regulating the operating status and various functions of the air conditioner, it needs to be electrically connected to the various electrical components within the air conditioner. Consequently, the electric control box 100 often contains multiple conductive wire harnesses 14, and the circuit board 12 also has many circuits. Due to the "electromagnetic" effect, the circuits generate many small magnetic fields. The magnetic fields generated by different circuits interfere with each other, affecting the function of the electric control box 100. Therefore, an electromagnetic interference shield is provided. This shield can release a magnetic field opposite to that generated by the circuits within the electric control box 100, thereby offsetting the magnetic field within the electric control box 100. Alternatively, sensitive devices within the electric control box 100 can be directly enclosed to reduce mutual interference between the multiple circuits within the electric control box 100.

[0037] In the prior art, the anti-electromagnetic interference component is usually placed directly in an idle position inside the shell 1, and lacks a corresponding fixed structure, which makes the anti-electromagnetic interference component easy to shake inside the shell 1, thereby causing the wire harness to swing or shift, affecting the normal function of the conductive harness 14. Therefore, a clip-on structure is provided between the shell 1 and the anti-electromagnetic interference component to fix the anti-electromagnetic interference component inside the shell 1. In addition, the anti-electromagnetic interference component is clipped and fixed to the shell 1, which also facilitates the installation of the anti-electromagnetic interference component.

[0038] In an embodiment of the present invention, the anti-electromagnetic interference component is configured as a degaussing coil 13, and the degaussing coil 13 is arranged next to the circuit board 12. Specifically, the degaussing coil 13 can generate a magnetic field opposite to the magnetic field generated by the circuit in the electric control box 100, thereby offsetting the magnetic field in the electric control box 100. The degaussing coil 13 can be electrically connected to the circuit board 12, and can also be electrically connected to the power supply in the electric control box 100. The degaussing coil 13 is arranged next to the circuit board 12, which helps the degaussing coil 13 to be close to the circuit board 12 and the conductive wire bundle 14, thereby improving the degaussing coil 13's offsetting effect on the magnetic field generated by the circuit board 12 and the conductive wire bundle 14 in the electric control box 100. In other embodiments, the degaussing coil 13 can also be arranged at other positions of the housing 1. In other embodiments, the anti-electromagnetic interference component can also be configured as a filter, a signal isolator, an optocoupler, etc.

[0039] To facilitate the installation of the degaussing coil 13, in the embodiment of the present utility model, please refer to Figure 1 and Figure 2A mounting slot 11 is provided in the housing 1, and the degaussing coil 13 is installed in the mounting slot 11. Specifically, the mounting slot 11 is provided inside the housing 1, and the degaussing coil 13 is fixed in the housing 1 by being installed in the mounting slot 11, thereby facilitating the installation of the degaussing coil 13. The mounting slot 11 can be directly adapted to the degaussing coil 13, so that the inner wall of the mounting slot 11 directly clamps the degaussing coil 13 therein, without the need to further clamp the degaussing coil 13 with the aid of other clamping structures. A clamping portion can also be further provided on the mounting slot 11, and when the degaussing coil 13 is installed in the mounting slot 11, the clamping portion is clamped to the mounting slot 11.

[0040] When the clamping portion is provided on the mounting slot 11, in the embodiment of the present utility model, please refer to Figure 2 and Figure 4 The mounting slot 11 has anti-dropout protrusions 111 on opposite sides of the slot edge. When the degaussing coil 13 is inserted into the mounting slot 11, the anti-dropout protrusions 111 engage with the opposite edges of the degaussing coil 13. Specifically, the anti-dropout protrusions 111 are provided on opposite sides of the slot and are arranged opposite to each other. When the degaussing coil 13 is inserted into the mounting slot 11, the two anti-dropout protrusions 111 engage with the opposite edges of the degaussing coil 13, thereby jointly clamping the degaussing coil 13 and fixing it in the mounting slot 11. The two anti-slipping protrusions 111 can be arranged on opposite sides of the degaussing coil 13 in the circumferential direction. At this time, the minimum distance between the two anti-slipping protrusions 111 is less than the diameter of the degaussing coil 13, thereby preventing the degaussing coil 13 from falling out of the mounting slot 11. Preferably, the height of the two anti-slipping protrusions 111 is greater than the radius of the degaussing coil 13, thereby improving the clamping stability of the anti-slipping protrusions 111 on the degaussing coil 13; the two anti-slipping protrusions 111 can be arranged on opposite sides of the degaussing coil 13 in the axial direction. At this time, the minimum distance between the two anti-slipping protrusions 111 is less than the diameter of the degaussing coil 13. 3, thereby preventing the degaussing coil 13 from falling out of the mounting slot 11, and preferably, the height of the two anti-falling protrusions 111 is greater than the radial thickness of the degaussing coil 13, at this time the degaussing coil 13 is installed in the mounting slot 11, the two anti-falling protrusions 111 are clamped on the inner circumference of the degaussing coil 13, the height of the two anti-falling protrusions 111 is greater than the diameter of the degaussing coil 13, at this time the degaussing coil 13 is installed in the mounting slot 11, the two anti-falling protrusions 111 are clamped on the outer circumference of the degaussing coil 13, thereby improving the clamping stability of the anti-falling protrusions 111 to the degaussing coil 13.

[0041] With this snap-fit ​​structure, during actual installation, the user only needs to directly insert the degaussing coil 13 into the mounting slot 11 to automatically snap-fit ​​the anti-dropping protrusion 111 to the degaussing coil 13, thereby facilitating the installation of the degaussing coil 13. In this solution, the mounting slot 11 is configured as a rectangular parallelepiped slot, and the degaussing coil 13 is inserted laterally into the mounting slot 11, thereby further facilitating the installation and removal of the degaussing coil 13 and reducing the space occupied by the degaussing coil 13 on the inner surface of the housing 1. Of course, in other embodiments, the mounting slot 11 can also be configured as a cylindrical or annular slot, and the degaussing coil 13 is inserted axially into the mounting slot 11.

[0042] In this embodiment, the anti-dropout protrusion can be directly integrated into the mounting slot 11, thereby ensuring the installation stability of the degaussing coil 13 and facilitating the assembly of the electric control box 100. The mounting slot 11 is also integrally formed in the housing 1, thereby further ensuring the installation stability of the degaussing coil 13 and facilitating the assembly of the electric control box 100.

[0043] To further facilitate the installation and removal of the degaussing coil 13, in an embodiment of the present invention, the sidewall of the mounting slot 11 is further provided with an escape notch 112, which is disposed between the two anti-dropout protrusions 111. Specifically, the escape notch 112 provides space for a human hand to escape during the actual installation of the degaussing coil 13. The operator can directly contact the degaussing coil 13 with his fingers through the escape notch 112 to remove the degaussing coil 13, thereby facilitating the installation and removal of the degaussing coil 13.

[0044] The fact that the escape notch 112 is disposed between the two anti-slip protrusions 111 does not mean that the escape notch 112 and the anti-slip protrusions 111 are on the same straight line. It only means that the two anti-slip protrusions 111 are spatially separated on opposite sides of the escape notch 112. For example, the two anti-slip protrusions 111 are disposed on two first side walls of the mounting slot 11 that are opposite to each other, and the two second side walls are spaced apart and connected to each other, and the escape notch 112 is disposed on the second side walls. To facilitate the formation of the mounting slot 11, in an embodiment of the present invention, two opposing and spaced-apart half-edges are disposed on the inner side of the housing 1. The two half-edges together enclose the mounting slot 11, and the gap between the two half-edges forms the escape notch 112.

[0045] See also Figures 1 to 5In an embodiment of the present invention, the electric control box 100 further includes a conductive wire harness 14. A wiring terminal 121 is provided on the circuit board 12. One end of the conductive wire harness 14 is connected to the wiring terminal 121, and the other end extends out of the housing 1 for connection with the electrical components in the air conditioner. Specifically, the electric control box 100 often has multiple conductive wire harnesses 14. Different conductive wire harnesses 14 are used for different power devices in the electric control box 100, thereby controlling the air conditioner to achieve multiple functions of the air conditioner. Therefore, one end of the conductive wire harness 14 is connected to the circuit board 12, and the other end extends out of the housing 1 for connection with the electrical components in the air conditioner. In order to facilitate the quick connection between the conductive wire harness 14 and the circuit board 12, a wiring terminal 121 is provided on the circuit board 12, thereby achieving quick connection between the conductive wire harness 14 and the circuit board 12, thereby facilitating the assembly of the electric control box 100.

[0046] Furthermore, a wiring bracket 15 is provided above the circuit board 12. A first wiring space 151 is formed on the side of the wiring bracket 15 facing away from the circuit board 12. The wiring bracket 15 forms a first projection onto the circuit board 12, and the connection terminals 121 are located on the circuit board 12 at locations other than the first projection. Specifically, the wiring bracket 15 forms a first wiring space 151 for the conductive wiring harness 14, thereby standardizing the layout of the conductive wiring harness 14 within the electrical control box 100 and reducing wire clutter. Furthermore, the first wiring space 151 is located on the side of the wiring bracket 15 facing away from the circuit board 12, separating it from the circuit board 12 and improving electrical safety within the electrical control box 100. In order to facilitate the quick connection between the conductive wire bundle 14 on the wiring bracket 15 and the wiring terminal 121, the wiring bracket 15 forms a first projection onto the circuit board 12, and the wiring terminal 121 is arranged at other positions of the circuit board 12 except the first projection, that is, the wiring terminal 121 is not located below the wiring bracket 15, thereby facilitating the quick connection between the conductive wire bundle 14 on the wiring bracket 15 and the wiring terminal 121, and also improving the electrical safety in the electric control box 100.

[0047] The first wiring space 151 can be formed solely by the wiring bracket 15, in which case a channel for placing the conductive wire harness 14 is defined within the wiring bracket 15. The first wiring space 151 can also be formed by the wiring bracket 15 and the inner wall of the housing 1. The electrical control box 100 can be provided with only one wiring bracket 15, with a portion of the conductive wire harness 14 arranged within the first wiring space 151. Alternatively, multiple wiring brackets 15 can be provided to form multiple first wiring spaces 151, allowing the conductive wire harnesses 14 to be arranged independently of each other, further improving electrical safety within the electrical control box 100.

[0048] See also Figure 1 and Figure 5To facilitate the installation of the wiring bracket 15, the wiring bracket 15 includes a main body 152 parallel to and spaced apart from the circuit board 12, and a mounting portion 153 extending toward the circuit board 12, and a fixing protrusion 154 is provided on the side of the mounting portion 153 away from the main body 152, and a plug-in slot 17 is provided on the side corresponding to the circuit board 12, and a card hole 171 is further provided on the side wall of the plug-in slot 17, the mounting portion 153 is plugged into the plug-in slot 17, and the fixing card protrusion 154 is plugged into the card hole 171, thereby facilitating the installation of the wiring bracket 15.

[0049] For further information, see Figures 1 to 3 The housing 1 also includes a second wiring space 16. The conductive wiring harness 14 includes a high-voltage harness and a low-voltage harness. The high-voltage harness is arranged in the first wiring space 151, and the low-voltage harness is arranged in the second wiring space 16. The circuit board 12 is provided with multiple terminals 121, with some of the multiple terminals 121 located near the first wiring space 151 and others located near the second wiring space 16. Specifically, the conductive wiring harness 14 is roughly divided into a high-voltage harness and a low-voltage harness. The high-voltage harness is primarily used for electrical connection of high-voltage components, which generally include drive motors, power supply systems, and control of high-power loads. The low-voltage harness is primarily used for electrical connection and signal transmission of low-voltage components, which generally include control circuits, safety protection, and user interfaces. The voltage difference between the high-voltage harness and the low-voltage harness is large, so a second wiring space 16 is provided, separated from the first wiring space 151. The high-voltage harness is arranged in the first wiring space 151, and the low-voltage harness is arranged in the second wiring space 16. This helps to achieve the separation of high and low voltage, thereby further improving the electrical safety of the distribution box. A plurality of connection terminals 121 are provided on the circuit board 12, and some of the plurality of connection terminals 121 are arranged close to the first wiring space 151 to facilitate the electrical connection between the high-voltage harness and the circuit board 12, and another portion is arranged close to the second wiring space 16 to facilitate the electrical connection between the low-voltage harness and the circuit board 12.

[0050] To facilitate the formation of the second wiring space 16, in an embodiment of the present invention, one side of the circuit board 12 abuts against the housing 1, and the other side is spaced apart from the housing 1, so as to enclose the housing 1 to form the second wiring space 16. Specifically, the second wiring space 16 is formed by utilizing the gap between the circuit board 12 and the inner wall of the housing 1, and a fixed edge is provided on one side of the circuit board 12 for fixing the circuit board 12. The fixed edge and the housing 1 together enclose the second wiring space 16, thereby eliminating the need for an additional wiring bracket 15, which helps to achieve the miniaturization of the electric control box 100. In addition, in the prior art, in order to achieve the separation of the high-voltage and low-voltage wire harnesses, the two sides of the circuit board 12 are usually spaced apart from the two sides of the housing 1, so that one side of the circuit board 12 forms the first wiring space 151, and the other side forms the second wiring space 16. Therefore, compared with the prior art, this solution helps to reduce the width of the electric control box 100, improve the space utilization rate of the electric control box 100, and contribute to the miniaturization of the electric control box 100.

[0051] Of course, in other embodiments, another wiring bracket 15 may be provided, on which a second wiring space 16 spaced apart from the first wiring space 151 is formed, or the wiring bracket 15 is provided with a first wiring space 151 and a second wiring space 16 spaced apart from each other.

[0052] The present invention also provides an air conditioner, comprising an indoor unit, an outdoor unit, a flexible connection assembly connecting the indoor and outdoor units, and an electric control box 100. The specific structure of the electric control box 100 is similar to that of the aforementioned embodiments. Since the present air conditioner utilizes all of the technical solutions of all of the aforementioned embodiments, it at least possesses all of the beneficial effects brought about by the technical solutions of the aforementioned embodiments, and therefore, no further description is given herein. The electric control box 100 is disposed in the indoor unit; in other embodiments, the electric control box 100 may also be disposed in the outdoor unit.

[0053] The above are merely exemplary embodiments of the present invention and are not intended to limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
