[0001] This utility model relates to the field of air conditioning technology, and more specifically, to a ceiling-mounted air conditioner. Background Technology

[0002] Ceiling-mounted air conditioning units are a common type of air conditioning equipment, widely used in commercial and residential environments. Their electrical control box is the core component controlling the operation of the air conditioner and needs to be reliably fixed to the unit casing.

[0003] However, the related technologies have at least one of the following problems: the electrical control boxes in the related technologies are mostly fixed with screws. Since the screw mounting holes on the housing are usually small and the installation field of vision is limited, it is very difficult to align the screws with the mounting holes. Repeated adjustments are often required, which makes the overall installation operation of the electrical control box inconvenient and the installation efficiency low. Utility Model Content

[0004] The technical problem solved by this utility model is that in related technologies, electrical control boxes are mostly fixed with screws. Since the screw mounting holes on the housing are usually small and the installation field of vision is limited, it is very difficult to align the screws with the mounting holes. Repeated adjustments are often required, which makes the overall installation operation of the electrical control box inconvenient and the installation efficiency low.

[0005] To solve the above problems, this utility model provides a ceiling-mounted air conditioner, comprising: a housing with a positioning and mounting portion; and an electrical control box with a connector that cooperates with the positioning and mounting portion to mount the electrical control box onto the housing. When the connector is in a first position relative to the positioning and mounting portion, the electrical control box is interlocked with the housing. When the connector is in a second position relative to the positioning and mounting portion, the electrical control box is movably mounted on the housing.

[0006] Compared with the prior art, the technical effects achieved by this technical solution are as follows: Compared with related technologies, this utility model provides a connector on the electrical control box. The connector cooperates with the positioning and mounting part. When the connector is in the first position relative to the positioning and mounting part, the electrical control box and the housing are interlocked and fixed to the housing. When the connector is in the second position relative to the positioning and mounting part, the electrical control box can move relative to the housing. When the electrical control box is fixed to the housing, the relative position of the electrical control box and the housing is fixed. At this time, it is more convenient to use screws to fix the electrical control box to the housing, and no alignment operation is required.

[0007] In one embodiment of this utility model, the electrical control box slides within the housing to allow the connecting member to switch between a first position and a second position relative to the positioning mounting part.

[0008] Compared with existing technologies, the technical effect achieved by adopting this technical solution is that the sliding movement of the electrical control box is linked with the position change of the connector, and the installer can directly judge the position of the connector by observing the displacement of the electrical control box.

[0009] In one embodiment of this utility model, the positioning mounting part has a positioning opening; the connector includes a snap-fit ​​part; wherein the snap-fit ​​part is installed to the positioning mounting part through the positioning opening, and the connector is in a second position.

[0010] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: the positioning opening provided on the positioning mounting part provides an entrance for the snap-fit ​​part on the connector, clarifying that the connector is installed into the positioning mounting part through the opening; and the snap-fit ​​part is installed into the positioning mounting part through the positioning opening, providing a path for the connector to enter the second position, ensuring that the initial installation position is uniform.

[0011] In one embodiment of this utility model, the positioning and mounting part further includes a limiting guide rail communicating with the positioning opening; the connecting part further includes a mating part, which is connected to the snap-fit ​​part; wherein, when the mating part is inserted into the limiting guide rail, the connecting part moves from the second position to the first position.

[0012] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: when the mating part is in the second state relative to the positioning and mounting part, it switches to the first state after being inserted with the limiting guide rail, forming an installation process from initial installation to adjustment to interlocking. Moreover, the state switching only requires sliding the mating part to the limiting guide rail, and fixing can be completed without tools. Furthermore, the limiting guide rail set on the positioning and mounting part provides a fixed path constraint for the sliding of the connecting parts. When the mating part is inserted along the limiting guide rail, the limiting guide rail can accurately control the sliding stroke.

[0013] In one embodiment of this utility model, the snap-fit ​​part is connected to the electrical control box through the mating part, and a first included angle is formed between the snap-fit ​​part and the mating part.

[0014] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the structural design in which the snap-fit ​​part and the mating part form a first included angle allows the connector to better fit the inner wall of the slide rail, reducing sliding resistance and improving sliding smoothness; at the same time, the included angle structure enhances the tightness of the contact between the connector and the slide rail, preventing loosening after assembly.

[0015] In one embodiment of this utility model, the housing is further provided with a first mounting hole; the electrical control box is provided with a first mating hole corresponding to the first mounting hole; wherein, when the connector is in the second position relative to the positioning mounting part, the first mounting hole is blocked; when the connector is in the first position relative to the positioning mounting part, the projection of the first mating hole onto the housing covers the first mounting hole.

[0016] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: when the connector is in the first position relative to the positioning mounting part, that is, when the control box and the housing are interlocked, the first mating hole covers the first mounting hole, and the hole position is automatically calibrated, and screws can be tightened through the aligned hole position; when the connector is in the second position relative to the positioning mounting part, the first mounting hole is blocked, and screws cannot be screwed in at this time.

[0017] In one embodiment of this utility model, the electrical control box includes a housing and a cover plate; a connector is disposed on the housing; and the cover plate is installed on the housing.

[0018] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the control box is divided into a shell and a cover, and the shell is equipped with connectors, which makes it easy to install the control box on the housing; while the cover is located on the shell, so that when performing subsequent maintenance or replacing internal components, it is not necessary to remove the shell from the housing, but only the cover needs to be removed, which greatly simplifies the maintenance steps, shortens the maintenance time, and reduces the maintenance difficulty and cost.

[0019] In one embodiment of this utility model, the outer shell is provided with a pressure plate; the cover plate is provided with a recess corresponding to the pressure plate; wherein, when at least a part of the structure of the pressure plate is embedded in the recess, the cover plate is fixedly disposed on the outer shell.

[0020] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the cover plate can be fixed without screws by using a quick-fixing structure with a pressure plate on the outer shell and a recess on the cover plate. That is, the pressure plate is embedded in the recess, and the cover plate can be installed or removed with simple operations such as pressing or prying the pressure plate.

[0021] In one embodiment of this utility model, the outer shell is provided with a second mounting hole; the cover plate is provided with a second mating hole corresponding to the second mounting hole; wherein, when the cover plate is fixedly mounted on the outer shell, the second mounting hole coincides with the second mounting hole.

[0022] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: By designing that the second mating hole and the second mounting hole coincide when the cover plate is fixed, it is ensured that the hole position is always accurately aligned after the cover plate is installed and removed. Subsequent operations such as installing screws can be carried out directly through this hole without adjusting the position of the cover plate, thus improving the accuracy and efficiency of operation; at the same time, it does not affect the quick fixing advantage of the pressure plate and the recess.

[0023] In one embodiment of this utility model, a fan is also included, which is disposed in the casing; the electrical control box is disposed relative to the fan.

[0024] By adopting the technical solution of this utility model, the following technical effects can be achieved: (1) The present invention provides a connector on the electrical control box. The connector cooperates with the positioning and mounting part. When the connector is in the first position relative to the positioning and mounting part, the electrical control box and the housing are interlocked and fixed to the housing. When the connector is in the second position relative to the positioning and mounting part, the electrical control box can move relative to the housing. When the electrical control box is fixed to the housing, the relative position of the electrical control box and the housing is fixed. At this time, it is more convenient to use screws to fix the electrical control box to the housing, and no alignment operation is required. (2) This utility model provides an entrance for the snap-fit ​​part on the connector by setting a positioning opening on the positioning mounting part, which clarifies that the connector is installed to the positioning mounting part through the opening; and the snap-fit ​​part can be directly positioned to the slide rail through the positioning opening, avoiding the situation where the connector cannot find the entrance and misaligned assembly during installation. In addition, the limiting guide rail set on the positioning mounting part provides a fixed path constraint for the sliding of the connector. When the mating part slides along the limiting guide rail in the first direction and is inserted, the limiting guide rail can accurately control the sliding stroke and avoid excessive sliding or offset. (3) The structural design of the snap-fit ​​part and the mating part forming a first included angle in this utility model allows the connector to better fit the inner wall of the slide rail, reduce sliding resistance, and improve sliding smoothness; at the same time, the included angle structure enhances the tightness of the contact between the connector and the slide rail, and avoids loosening after assembly.
