[0037] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0039] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0040] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0041] In existing ventilation systems, electrical boxes are fixedly installed on the air duct. This installation method obstructs the airflow, preventing components downstream of the air duct that require cooling or heat exchange from being effectively cooled or heated.

[0042] Therefore, the present invention proposes a method for placing an electrical box on an air duct. The electrical box is slidably placed on the air duct so that the area of ​​the electrical box blocking the air duct can be adjusted. When the ventilation system with the electrical box is running, the position of the electrical box on the air duct can be adjusted so that the area of ​​the electrical box blocking the air duct can be adjusted to avoid obstructing the airflow and causing the heat exchange effect of the downstream heat exchange components to deteriorate.

[0043] Example 1

[0044] refer to Figures 1 to 3 The present invention provides an electrical box assembly, including an electrical box body 11 and a slider 12, wherein the slider 12 can slide along a first direction with the electrical box body 11.

[0045] Preferred, such as Figure 2 As shown, the slider 12 is a slider 12, which is detachably connected to the electrical box body 11, making it easy to disassemble and assemble the electrical box body 11; the electrical box assembly also includes a driving component, which is drivenly connected to the slider 12, and can drive the slider 12 and the electrical box body 11 to slide synchronously, so as to adjust the position of the electrical box body 11, and thus adjust the shielding area of ​​the electrical box body 11 on the air path.

[0046] Furthermore, the connection between the slider 12 and the electrical box body 11 is a magnetic connection; preferably, an electromagnetic switch device is provided between the slider 12 and the electrical box body 11; by controlling the state of the electromagnetic switch device, the magnetic connection state between the slider 12 and the electrical box body 11 can be controlled, thereby realizing the connection or non-connection of the slider 12 and the electrical box body 11; when the two need to be connected together, the electromagnetic switch device is in the closed state, and the slider 12 and the electrical box body 11 generate a magnetic attraction and are connected together, the connection is reliable and not easy to fall off; when the two do not need to be connected together, the electromagnetic switch device is in the open state, and the slider 12 and the electrical box body 11 do not generate a magnetic attraction, at which time the electrical box body 11 can be detached from the slider 12, and disassembly is convenient.

[0047] Specifically, the electromagnetic switch device includes a permanent magnet, an electromagnet, and a rechargeable battery. The permanent magnet is located inside the slider and close to the electrical box body 11; the electromagnet is located inside the electrical box body 11 and close to the slider; the rechargeable battery is located inside the electrical box body 11 and is used to supply power to the electromagnet. The state of the electromagnetic switch device can be controlled by controlling the rechargeable battery to supply power to or de-supply the electromagnet. When the rechargeable battery supplies power to the electromagnet, the electromagnet and the permanent magnet are magnetically attracted together, and the electromagnetic switch device is in a closed state. When the rechargeable battery does not supply power to the electromagnet, the electromagnet and the permanent magnet do not interact, and the electromagnetic switch device is in an open state.

[0048] When the electrical box body 11 needs to slide along the first direction, the electrical box body 11 and the slider 12 are magnetically connected to prevent the electrical box body 11 from sliding along the second direction and falling off the slider 12; when the electrical box body 11 needs to be disassembled, the electromagnetic switch device is in the open state, so that the electrical box body 11 and the slider 12 are not connected, and the electrical box body 11 can be separated from the slider 12.

[0049] Furthermore, such as Figure 2 As shown, the slider 12 is provided with a groove 121, the groove 121 extends along the second direction and the electrical box body 11 is embedded in the groove 121, the second direction is perpendicular to the first direction; preferably, the first direction is the length direction of the electrical box body 11 and the second direction is the width direction of the electrical box body 11.

[0050] When the electromagnetic switch is in the open state, the electrical box body 11 is not connected to the slider 12. The electrical box body 11 can slide along the slide groove 121 and can be removed from the slider 12. The structure is simple, which makes it easy to install or disassemble the electrical box body 11, and also makes it easy to repair or replace the electrical box body 11.

[0051] Specifically, the slider 12 can have an upper working surface and a lower working surface. The upper working surface has a groove 121, in which the electrical box body 11 is embedded. When it is necessary to disassemble the electrical box body 11, the electrical box body 11 is slid along the groove 121 and removed from the slider 12. The lower working surface allows the slider 12 to carry the electrical box body 11 and slide in the first direction to adjust the position of the electrical box body 11 and the wind-blocking area of ​​the electrical box body 11 on the air passage.

[0052] To address the issue that the electrical box body 11 cannot achieve automatic control, this embodiment proposes that the electrical box body 11 is provided with a first detection unit, which includes a pressure sensor. The pressure sensor is used to detect the pressure on the electrical box body 11 in a first direction and cause the electrical box body 11 to slide along the first direction to adjust the position of the electrical box body 11. When a slight force is applied to the electrical box body 11 to the left, the electrical box body 11 automatically slides to the left; when a slight force is applied to the electrical box body 11 to the right, the electrical box body 11 automatically slides to the right.

[0053] In addition, the electrical box body 11 or the slider 12 is also provided with a second detection unit. The second detection unit includes an optical sensor. The optical sensor is used to detect the brightness at the location of the electrical box body 11 and determine whether to control the electrical box body 11 to slide along the first direction based on the detected brightness, so as to adjust the position of the electrical box body 11. When the brightness detected by the optical sensor is less than the preset brightness, the electrical box body 11 can automatically slide along the first direction until the brightness detected by the optical sensor is equal to or greater than the preset brightness.

[0054] For the above-mentioned electrical box assembly, in order to facilitate the slidable installation of the electrical box body 11 on the air duct, the electrical box assembly also includes a slide rail 13, on which a sliding member 12 is slidably provided, so that the electrical box body 11 and the sliding member 12 can slide on the slide rail 13 along the first direction.

[0055] Example 2

[0056] This embodiment is an application of Example 1 to an air-cooled air conditioner, specifically an air-cooled computer room air conditioner. The air-cooled air conditioner includes a frame 21 and an evaporator 22. The electrical box body 11 is slidably mounted on the frame 21 via a sliding member 12 and is located upstream of the air path of the evaporator 22. By sliding the electrical box body 11 along the first direction, the area of ​​the electrical box body 11 that blocks the air path can be adjusted.

[0057] When the air-cooled air conditioner is required to operate, the electromagnetic switch device is closed, and the electrical box body 11 can slide along the first direction to the rightmost side of the frame 21, adjusting the area of ​​the electrical box body 11 blocking the air passage, improving the ventilation efficiency of the air-cooled air conditioner, and avoiding the problem of the electrical box body 11 blocking the wind.

[0058] When it is necessary to disassemble the electrical box body 11, the electromagnetic switch device is turned on, and the electrical box body 11 can slide along the second direction, thereby the electrical box body 11 can be removed from the slider 12.

[0059] like Figure 6 The diagram shows the method for adjusting the position of the electrical box body 11 when the electrical box assembly is installed in the air duct of an air-cooled air conditioner:

[0060] First, it is determined whether the air conditioner needs to be operated. When the air conditioner needs to be operated, the pressure sensor detects whether the electrical box body 11 is subjected to pressure to the right. When the pressure sensor detects that the electrical box body 11 is subjected to pressure to the right, the slider 12 is controlled to slide the electrical box body 11 to the right side of the frame 21. When the air conditioner does not need to be operated, it means that the air conditioner needs to be maintained. The pressure sensor detects whether the electrical box body 11 is subjected to pressure to the left. When the pressure sensor detects that the electrical box body 11 is subjected to pressure to the left, the slider 12 is controlled to slide the electrical box body 11 to the left side of the frame 21 and slide to the leftmost side of the frame 21.

[0061] Secondly, when the slider 12 slides the electrical box body 11 to the right side of the frame 21, the brightness of the electrical box body 11 at the location is detected by the optical sensor and compared with the preset brightness. When the brightness is less than the preset brightness, it is determined that the electrical box body 11 is not at the far right of the frame 21, and the slider 12 is controlled to slide the electrical box body 11 to the far right of the frame 21.

[0062] Finally, when the electrical box body 11 is on the far right of the frame 21, the air conditioner is controlled to operate normally.

[0063] Example 3

[0064] This embodiment is an application of Example 1 to an air-cooled air conditioner, specifically an air-cooled computer room air conditioner. The air-cooled air conditioner includes a frame 21 and an evaporator 22. The slide rail 13 of the electrical box assembly is set on the frame 21 or integrally formed with the frame 21. The structure is simple and easy to assemble manually, which helps to improve the efficiency of production assembly. The electrical box body 11 is slidably set on the frame 21 and located upstream of the air path of the evaporator 22 through the cooperation of the sliding member 12 and the slide rail 13. By sliding the electrical box body 11 along the first direction, the shading area of ​​the electrical box body 11 on the air path can be adjusted.

[0065] Specifically, such as Figure 3 As shown, the slide rail 13 is mounted on the frame 21, and the slider 12 is slidably engaged with the slide rail 13. The slider 12 engages with the electrical box body 11 through the slide groove 121. When the electromagnetic switch device is in the closed state, the slider 12 can drive the electrical box body 11 to slide along the slide rail. When the electromagnetic switch device is in the open state, the electrical box body 11 slides in the second direction, and the electrical box body 11 can be detached from the slider.

[0066] like Figure 4a As shown, when other components of the air conditioner need maintenance, adjust the electrical box body 11 to the leftmost position of the slide rail 13; as... Figure 4b As shown, when the air conditioner needs to operate normally, the electrical box body 11 is adjusted to the rightmost side of the slide rail 13 to prevent the electrical box body 11 from blocking the wind when the ventilation system is running.

[0067] like Figure 5a and Figure 5b As shown, when the air conditioner needs to operate normally, the optical sensor detects the brightness and determines that the electrical box body 11 is not on the far right of the slide rail 13. Then, it controls the slider 12 to move the electrical box body 11 to the far right of the slide rail 13. At this time, the electrical box body 11 can be removed from the slider 12 when it is on the far right of the slide rail 13.

[0068] The air-cooled air conditioner 2 is a modular air-cooled computer room air conditioner. The setting of the slider 12 and the electromagnetic connection between the slider 12 and the electrical box body 11 effectively solve the problem of disassembly and maintenance of the electrical box. It provides functions such as air circulation, air filtration, cooling, reheating and humidity control for places such as computer rooms, switch rooms, data rooms, transmission rooms, power supply rooms, electronic rooms and electronic equipment rooms to ensure that the equipment environment meets the normal use requirements.
