[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0031] To address the technical problem of poor ease of production, installation, and maintenance of air conditioners in related technologies, this invention provides an air conditioner and an air conditioner control method.

[0032] like Figures 1 to 8 As shown, the air conditioner includes: an assembly assembly comprising an electrical box module 10 and an electric heating module 20, the electric heating module 20 being electrically connected to the electrical box module 10; and a housing. The assembly assembly is movable relative to the housing and has a working position installed inside the housing and a maintenance position extending outside the housing. By combining the electrical box module 10 and the electric heating module 20, wiring of the electric heating module 20 can be completed during pre-assembly, improving assembly efficiency and thus production efficiency. It also reduces wiring difficulty, enhancing the convenience of air conditioner production and installation. Furthermore, when maintenance of the electric heating module 20 is required, the assembly assembly can move as a whole relative to the housing to the maintenance position, allowing maintenance without disassembling the fan, thus improving maintenance convenience and efficiency.

[0033] Optionally, the location of the electric heating module 20 can be set according to actual needs.

[0034] Optionally, the electric heating module 20 is installed inside the air cavity, which can ensure that the air is heated evenly and also ensure the convenience of unit production, installation and maintenance.

[0035] Optionally, the assembly component moves relative to the housing via a sliding component 30. The sliding component 30 includes a slide rail 31 and a slider 32, with the slider 32 slidably connected to the slide rail 31. The slide rail 31 is fixedly disposed within the housing, and the slider 32 is fixedly connected to the assembly component. The assembly component is slidably disposed between the working position and the maintenance position. This allows the assembly component to move between the working position and the maintenance position by pulling it out, resulting in a simple structure, convenient operation, and improved maintenance efficiency and convenience.

[0036] Optionally, the sliding component 30 provides guidance and limits for the movement of the assembly component, making it easier for the assembly component to move between the working position and the maintenance position.

[0037] Optionally, the sliding direction of the sliding component 30 can be selected according to actual needs.

[0038] In an optional embodiment not shown in this application, the slider 32 may be fixedly disposed inside the housing, and the slide rail 31 may be fixedly connected to the assembly component.

[0039] In an optional embodiment not shown in this application, the sliding component may be omitted, and the assembly component may be relatively freely and movable within the housing. A separate limiting structure may be provided. When the assembly component is installed in the working position, the limiting structure is used to limit it. When maintenance is required, the limiting structure is released, and the assembly component is removed.

[0040] Optionally, the air conditioner also includes a limit switch 40, which is disposed on the assembly component or inside the housing. When the assembly component is in the working position, the limit switch 40 is activated and in the open state; when the assembly component is in the maintenance position, the limit switch 40 is in the closed state. In this way, the position of the assembly component can be determined by the limit switch 40, allowing the air conditioner to achieve precise control based on the position of the assembly component.

[0041] Optionally, the air conditioner also includes a control module. After the air conditioner is powered on, its low-voltage power is connected. The control module controls the high-voltage power of the air conditioner based on the state of the limit switch 40. When the limit switch 40 is in the open state, the control module controls the high-voltage power of the air conditioner to be connected; when the limit switch 40 is in the closed state, the control module controls the high-voltage power of the air conditioner to be disconnected. In this way, the high-voltage power can be automatically cut off for protection during maintenance, adding a maintenance identification function to the air conditioner to ensure maintenance safety.

[0042] Optionally, when the air conditioner includes a sliding assembly 30 and a limit switch 40, the limit switch 40 is disposed inside the housing and located inside the slide rail of the sliding assembly 30.

[0043] like Figure 4 As shown, the electric heating module 20 includes: an electric heating bracket 21; electric heaters 22, with multiple electric heaters 22 mounted on the electric heating bracket 21; the assembly also includes a support frame 50, through which the electrical box module 10 is connected to the electric heating bracket 21. Thus, using multiple electric heaters 22 improves heating efficiency, and the electric heating module 20 and the electrical box module 10 are combined together via the support frame 50.

[0044] Optionally, the electrical box module 10 is fixedly connected to the support frame 50 by screws.

[0045] Optionally, the electric heating bracket 21 can be reshaped to meet actual usage requirements.

[0046] like Figure 4 and Figure 5 As shown, the air conditioner also includes heat exchangers 1, with the distance between the two heat exchangers 1 gradually increasing from the first end to the second end. When the assembly is in the working position, the electrical box module 10 is located between the two heat exchangers 1 and flush with the ends of the two heat exchangers 1. The two heat exchangers 1 and the electrical box module 10 form an air cavity, and the electric heating module 20 is located inside the air cavity. In this way, the installation position of the electric heating module 20 can ensure that the air can be heated evenly.

[0047] like Figure 4 As shown, the electrical box module 10 is generally triangular in shape, with a slider 32 connected to each of its three ends; a slide rail 31 is provided between the first ends of the two heat exchangers 1, and a slide rail 31 is provided on the side wall of each of the second ends of the two heat exchangers 1; the electric heating module 20 includes an electric heating bracket 21 and multiple electric heaters 22 disposed on the electric heating bracket 21. The electric heating bracket 21 includes a connecting plate 211 and two mounting plates 212, which are respectively disposed at both ends of the connecting plate 211. The distance between the two mounting plates 212 gradually increases in the direction away from the connecting plate 211. The ends of the two mounting plates 212 away from the connecting plate 211 are respectively connected to a slider 32, and multiple electric heaters 22 are disposed on each of the two mounting plates 212; the assembly assembly also includes a support frame 50, which is connected between the mounting plate 212 and the electrical box module 10. Thus, the assembly assembly and sliding assembly provided in this application can be used in air conditioners with V-shaped heat exchangers, and the assembly assembly moves smoothly.

[0048] like Figure 3As shown, the air conditioner also includes a limit switch 40, which is installed inside a slide rail 31. When the assembly component is in the working position, the slider 32 touches the limit switch 40, and the limit switch 40 is in the open state. When the status component is in the maintenance position, the slider 32 does not touch the limit switch 40, and the limit switch 40 is in the closed state. In this way, by combining the limit switch 40 with the sliding component 30, the position of the assembly component is determined by the limit switch 40, thereby enabling the air conditioner to perform precise control based on the position of the assembly component.

[0049] Optionally, the line 3 connected to the electric heating module 20 extends along the slide rail 31; and / or the line 3 connected to the electrical box module 10 extends along the slide rail 31. In this way, the wiring of the electric heating module 20 and the electrical box module 10 is convenient.

[0050] like Figure 6 and Figure 8 As shown, the air conditioner also includes: a pull cord 2, which is installed inside the housing and connected to the wiring 3, providing a downward pulling force; when the assembly is in the working position, a portion of the wiring 3 is piled up under the pull cord 2; when the assembly moves from the working position to the maintenance position under the action of external force, the wiring 3 is pulled out to its maximum length against the pulling force. Thus, with the help of the pull cord 2, the wiring 3 is less likely to be damaged during the pulling process of the assembly.

[0051] This application also provides a control method for an air conditioner, which is the type described above or below. The control method includes the following steps: determining the position of the air conditioner's assembly components; when the assembly components are determined to be in the working position, controlling the air conditioner's high-voltage power supply to be connected; when the assembly components are determined to be in the maintenance position, controlling the air conditioner's high-voltage power supply to be disconnected. This adds a maintenance identification function to the air conditioner, automatically disconnecting the high-voltage power supply during maintenance to ensure maintenance safety.

[0052] Optionally, the air conditioner is the aforementioned type including a limit switch, and the control method includes the following steps: When the air conditioner is turned on, its low-voltage power is connected. It is determined whether the limit switch is in the open state. If yes, the high-voltage power is connected, and the air conditioner begins to work; if not, the high-voltage power is disconnected, and the air conditioner stops working. After the air conditioner starts working, it is continuously determined whether the limit switch is in the open state. If yes, the high-voltage power is connected, and the air conditioner continues to work; if not, the high-voltage power is disconnected, and the air conditioner stops working. In this way, the position of the assembly components is determined by the limit switch, ensuring maintenance safety.

[0053] In optional embodiments not illustrated in this application, in addition to limit switches, other methods can be used to determine the position of the assembly components, such as proximity switches.

[0054] This application provides a structure that combines an electrical box module and an electric heating module, making them an integrated unit. This facilitates the installation of both the electrical box module and the electric heating module, streamlines the wiring for the electric heating element, and significantly improves assembly efficiency. Furthermore, the pull-out structure allows the electrical box module to be pulled out together with the electric heating module, enabling disassembly and maintenance of the electric heating module without disassembling the entire fan module, thus solving a major after-sales problem.

[0055] Optionally, the assembly components provided in this application are suitable for air conditioners with V-shaped heat exchangers and where the electric heating element needs to be placed in the air cavity in the middle of the heat exchanger.

[0056] Optionally, the air conditioner is a chilled water server room air conditioner. With the advent of the big data era, the scale of data centers is gradually expanding, and the heat generated by the components within the data centers is also gradually increasing. To ensure timely heat dissipation, many data centers currently use chilled water server room air conditioners to regulate the temperature and humidity of the data center. Chilled water server room air conditioners are divided into two types: top-supply air units and bottom-supply air units. The illustrated embodiment of this application is a top-supply air unit.

[0057] The electric heating module and the electrical box module provided in this application are combined and placed in the air cavity, which can ensure that the air can be heated evenly and also ensure the convenience of unit production, installation and maintenance.

[0058] In related technologies, the electrical box module and the electric heating module are separate modules, installed independently in different locations. Taking a chilled water supply air conditioning unit as an example, the electrical box module is installed on the surface cooler connection plate, while the electric heating module is installed inside the V-shaped heat exchanger, below the fan cavity. This structure requires that the electric heating wiring be done only after both the electric heating components and the electrical box components are installed, reducing assembly efficiency. Furthermore, because the electric heating module is located below the fan cavity, if the electric heating malfunctions after maintenance, the upper fan module must be disassembled for repair, which is extremely inconvenient for after-sales maintenance.

[0059] In the specific embodiments provided in this application, such as Figures 1 to 9 As shown, the electric heating module 20 of the air conditioning unit of the present invention is connected to the electrical box module 10 by a support frame 50, and then the sliding component 30 connects the electric heating module 20 and the electrical box module 10. Under normal working conditions, such as Figure 5 As shown, the sliding component 30 is installed in the unit at its shortest contraction limit, and the electric heating module is located in the middle of the air cavity, ensuring that the air inside the air cavity is heated evenly. During maintenance and installation of the air conditioning unit of this invention, as... Figure 7As shown, the sliding assembly 30 is installed in the unit at its longest tensile limit. When the sliding assembly 30 is in this state, the electrical box module and the electric heating module connected to it extend out of the unit's air cavity. During installation, the electrical wiring is as follows: Figure 6 and Figure 8 As shown, the wiring of the electrical box module 10 and the electric heating module 20 can extend along the sliding assembly 30 all the way to the main body of the unit. Since the sliding assembly 30, the electric heating module 20, and the electrical box module 10 are pre-assembled as a single unit, the wiring can be completed before assembly, eliminating the need for rewiring during later production. During maintenance, the electrical box module 10 can be pulled out to access the electric heating module 20. When the sliding assembly 30 is in its shortest retracted limit state, it touches the limit switch 40, opening the switch and placing the electrical box module 10 in its normal operating position, connecting the unit to the high-voltage power supply. When the electrical box module 10 is extended for maintenance, the limit switch 40 closes, disconnecting the unit from the high-voltage power supply. Figure 9 As shown. Figures 1 to 4 As shown, the integrated structure of the electric heating module and the electrical box module is connected by a support frame 50 to the electrical box module 10 and the electric heating module 20. The electric heater 22 is mounted on the electric heating bracket 21. Three sliding components 30 are respectively connected to the bottom and top sides of the electrical box module 10. The sliding components 30 on the top sides are also connected to the electric heating bracket 21. The three sliding components 30 are respectively installed on the unit to complete the overall installation. Figure 5 The cable puller 2 provides a downward pulling force to the cable. When the electrical box module 10 is pulled out, the cable is extended to its maximum length. When the electrical box module 10 is working, the cable is at its shortest length. Excess cable accumulates below the cable puller and does not affect the unit. This application combines the electric heating module with the electrical box module, completing the electric heating wiring during pre-installation, thus improving production efficiency. By combining the electrical box module 10, the electric heating module 20, and the sliding component 30, the electrical box module 10 and the electric heating module 20 can be pulled out along with the slider 32, facilitating after-sales maintenance. Furthermore, the invention includes a maintenance identification function, automatically cutting off power during maintenance to ensure maintenance safety.

[0060] Optionally, the wiring of the electric heating module 20 and the electrical box module 10 is consistent, and the electric heating module 20 enters the electrical box module 10 along the sliding component 30 for control.

[0061] Optionally, the electrical box module 10, the support frame 50, and the electric heating bracket 21 are connected by screws. The electric heater 22 and the electric heating bracket 21 are also connected by screws.

[0062] The technical problems solved by this invention include at least the following: difficulty in electrical wiring during electric heating production and processing; difficulty in after-sales maintenance of electric heating; and ensuring the safety of after-sales repair.

[0063] The beneficial technical effects of this invention include at least the following: combining the electric heating module with the electrical box module, this structure is more conducive to the installation and maintenance of the electric heating. The electric heating module and the electrical box module can be wired during pre-assembly, improving assembly efficiency and reducing wiring difficulty. An automatic power-off mechanism for maintenance is provided to ensure maintenance safety.
