Description

Technical Field

[0001] This utility model relates to the field of air conditioning unit technology, specifically to an air conditioning unit that is easy to install. Background Technology

[0002] An air conditioning unit typically includes components such as an indoor unit, condensate drain pipes, and a filter. Ceiling-mounted or recessed indoor units are usually installed on the roof using brackets.

[0003] Existing technology uses brackets that are fixed to the roof with bolts. The air conditioning unit casing has multiple mounting ears on its outer side, and the brackets are fixed to these ears via connectors, thus securing the air conditioning unit under the roof. However, this method of fixing the air conditioning unit to the bracket with multiple bolts is cumbersome and requires at least two workers to install. For ceiling-mounted or recessed indoor units, the limited space above the ceiling makes it difficult for multiple people to work together, making installation and disassembly inconvenient. Furthermore, the bracket length must be cut according to the size and height of the casing to avoid being too short or too long, which would affect the installation. This method of bracket cutting is also inconvenient. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides an air conditioning unit that is easy to install.

[0005] The technical solution of this utility model is as follows:

[0006] An easy-to-install air conditioning unit is installed on the inner upper side of the roof. The air conditioning unit includes a housing. Two connecting units are symmetrically arranged on the lower surface of the roof. The upper part of the housing has hanging ears corresponding to the connecting units on opposite sides. The lower part of the housing has connecting ear plates on opposite sides.

[0007] The connection unit includes a detachably connected L-shaped connecting plate and an L-shaped limiting plate. The upper part of the L-shaped connecting plate is connected to the roof through a first connector. The lower part of the L-shaped connecting plate is provided with a hook groove on the side near the shell, and the hanging ears can be inserted into the adjacent hook groove.

[0008] The upper part of the L-shaped limiting plate slides with the L-shaped connecting plate in a vertical direction. The L-shaped limiting plate is located on the side of the L-shaped connecting plate away from the housing. The lower end of the L-shaped limiting plate is detachably connected to the connecting ear plate through a second connector.

[0009] Two connecting units are symmetrically arranged on both sides of the air conditioning unit. The hanging ears on both sides of the air conditioning unit casing can be inserted into the hook slots of the L-shaped connecting plate. The L-shaped connecting plate provides a pre-fixing effect for the air conditioning unit. The L-shaped limiting plate fixes the connecting ear plate at the bottom of the casing through the second connecting piece. The height of the L-shaped limiting plate can be adjusted according to the position of the connecting ear plate of different casings, so that both the upper and lower parts of the casing can be effectively fixed. The installation process can be operated by a single person and is suitable for installing ceiling-mounted or recessed indoor units in narrow spaces.

[0010] To facilitate inserting the hanging ears into the hook slots by raising the housing, the vertical distance between the upper end face of the hook slot and the lower surface of the roof is greater than the vertical distance between the lower surface of the hanging ear and the upper end face of the air conditioning unit.

[0011] The connection structure of the L-shaped connecting plate and the L-shaped limiting plate is as follows: the L-shaped connecting plate includes a vertically connected vertical plate and a horizontal plate. The horizontal plate is located close to the housing. The hook groove is located on the horizontal plate. The vertical plate has a sliding groove in the vertical direction. The upper part of the L-shaped limiting plate has a sliding block. The sliding block slides in the sliding groove. The L-shaped limiting plate can move closer to or further away from the adjacent hook in the horizontal direction.

[0012] Regarding the connection structure between the L-shaped limiting plate and the hanging ear, the L-shaped limiting plate is connected to the hanging ear via a connection structure on the side near the hanging ear. The connection structure includes insert teeth set on the side of the sliding block near the hanging ear. The insert teeth are set in the horizontal direction. The side of the hanging ear near the L-shaped limiting plate is provided with slots that cooperate with the insert teeth. Multiple slots are arranged in parallel in the vertical direction.

[0013] To ensure that the inserts can be inserted into the slots at different heights, there are multiple inserts, and the number of inserts is less than the number of slots.

[0014] To secure the hook ear in the hook groove, a third connector is provided on one side of the lower part of the L-shaped connecting plate. The third connector is set in the horizontal direction and can pass through the hook groove and be pressed against the outer surface of the hook ear.

[0015] The connection structure between the lower part of the L-shaped limiting plate and the connecting ear plate is as follows: the lower part of the L-shaped limiting plate is located on the upper side of the connecting ear plate, and the second connecting piece passes through the L-shaped limiting plate and the connecting ear plate from top to bottom and is connected to the fastener. The fastener is a fastening nut, which is located below the connecting ear plate. The lower part of the L-shaped limiting plate is located on the upper side of the connecting ear plate, so that when the fastener is tightened, the lower part of the L-shaped limiting plate can be pressed downward, so that the upper teeth of the L-shaped limiting plate can be pressed into the slot, which facilitates the connection unit to fix the housing.

[0016] To achieve the above-mentioned ability to adjust the height of the L-shaped limiting plate according to the size of the housing, the height of the sliding block is set to be less than the length of the sliding groove, so that the L-shaped limiting plate can move upward within the sliding groove to a certain height.

[0017] The beneficial effects of this utility model are as follows:

[0018] Two connection units are installed on the lower surface of the roof. The two connection units are located on both sides of the air conditioning unit casing. The lugs on both sides of the casing can be inserted into the hook slots of the connection units to pre-install the casing. The lugs can be fixed in the hook slots by fasteners, so that the upper part of the casing is fixedly connected to the L-shaped connection plate.

[0019] The lower two sides of the housing are fixed to the second connector by L-shaped limiting plates. The upper part of the L-shaped limiting plate can move up and down inside the L-shaped connecting plate to adjust the distance between the bottom of the L-shaped limiting plate and the adjacent connecting ear plate. When the bottom of the L-shaped limiting plate is close to the upper surface of the adjacent connecting ear plate, the connecting ear plate is connected to the L-shaped limiting plate by the second connector, which is convenient for installation and disassembly. It can be operated by a single person and is suitable for installing ceiling-mounted indoor units or recessed indoor units in narrow spaces.

[0020] To facilitate adjustment of the distance between the bottom of the L-shaped limiting plate and the adjacent connecting ear plate, insert teeth are provided on the sliding block at the top of the L-shaped limiting plate, and slots are provided on one side of the connecting ear plate. The lower part of the L-shaped limiting plate is located at the top of the connecting ear plate, so that when the fasteners are tightened, the lower part of the L-shaped limiting plate can be pressed downwards, so that the insert teeth at the top of the L-shaped limiting plate can be pressed into the slot, which facilitates the connection unit to fix the housing.
