At present, a duct-type air conditioner is usually provided with a cuboid-shaped shell 100, and various components for making cold air or hot air, such as a chassis component, an electric control module, a wind turbine fan module, a water receiving tray and an evaporator, are placed inside the shell 100. The shell 100 may be enclosed by an upper cover plate, a lower cover plate, a lower enclosure plate and a piping pressing plate. Two ends of the shell 100 in a length direction are provided with an air return opening 110 and an air outlet, respectively. A filter screen 300 is generally provided at the air return opening 110 for filtering air entering the shell 100. During the operation of the duct-type air conditioner, the air is sucked from the air return opening and discharged from the air outlet after being cooled or heated. In order to make the filter screen 300 be stably mounted at the air return opening 110, a clamp plate 200 for the filter screen 300 is usually provided at the air return opening 110. At present, the clamp plate 200 is generally made rectangular, and two ends of the clamp plate in a length direction are connected and fixed to left and right side walls 120 of the air return opening 110, respectively. The clamp plate 200 has the function of clamping and fixing the filter screen 300 to the air return opening 110 of the shell 100.

When the filter screen 300 is inserted into the slot, the magnetic component at the top of the filter screen 300 is attracted to a top side wall of the shell 100. After the filter screen 300 is inserted into the slot of the shell 300 from top to bottom, a bottom of the filter screen 300 abuts against a bottom of the shell 300, the magnet on the filter screen 300 is opposite to an end face of the top side wall of the shell 300, and the magnet can be attracted and attached to the end face of the top side wall of the shell 300. The way of attaching the filter screen 300 to the shell 100 by the magnetic component can reduce the use of screws and other connectors, thereby the assembling and disassembling of the filter screen 300 in the slot is facilitated, and the assembling and disassembling efficiency of the filter screen 300 is improved.
With reference to
One reinforcement rib 250 is formed in the middle portion of the fixation plate 210 by stamping. The first clamp plate folded edge 220, the second clamp plate folded edge 230, the edge plate 240 and the reinforcement rib 250 are simultaneously arranged on the same side surface of the fixation plate 210, thereby the strength of the clamp plate 200 can be effectively increased, and the clamp plate 200 is difficult to bend and deform during transportation. The protrusion of the reinforcement rib 250, the first clamp plate folded edge 220 and the second clamp plate folded edge 230 are arranged on the same side surface of the fixation plate 210, which is close to the side where the filter screen 300 of the shell 100 is installed, so that the second clamp plate folded edge 230 and the fixation plate 210 provide a position for the palm to exert force during carrying, without bringing discomfort to the palm due to the protruding of the reinforcement rib 250 and the first clamp plate folded edge 220 on the side surface of the fixation plate 210. The fixation plate 210 is formed in a rectangular shape, and the first clamp plate folded edge 220, the second clamp plate folded edge 230 and the edge plate 240 are also formed in a rectangular shape. The first clamp plate folded edge 220 and the second clamp plate folded edge 230 are respectively arranged at 90° with the fixation plate 210, and the first clamp plate folded edge 220, the second clamp plate folded edge 230 and the reinforcement rib 250 are arranged in parallel to each other. Rounded corners are arranged at each end pin of the fixation plate 210, the first clamp plate folded edge 220 and the edge plate 240, which can reduce a situation that the installer is cut by sharp end pins during mounting.
Each of the two left and right side walls 120 of the air return opening 110 of the shell 100 is provided with a folded edge in a vertical direction, so the side walls have a certain thickness. By arranging the avoidance notches 260 at the two ends of the clamp plate folded edge 230 and the edge plate 240, when the clamp plate 200 is mounted, the mounting members 211 at the two ends of the fixation plate 210 are fixedly connected to the folded edges of the two side walls 120, and the second clamp plate folded edge 230 and the edge plate 240 can be smoothly embedded into the cavity of the shell 100 through the air return opening 110, such that a side surface of the fixation plate 210 extending to outside is flat. A top of the filter screen 300 may be provided with a magnet. When the filter screen 300 is inserted into the slot formed by the enclosure of the clamp plate 200 and the shell 100, the magnet can be attracted and attached to a part of the shell 100 opposite to the top of the filter screen 300. It is convenient to disassemble the filter screen 300 by a magnetic component. The top of the filter screen 300 may be provided with a shell, and the magnet is embedded in the shell. After the filter screen 300 is mounted into the slot, the shell at the top of the filter screen 300 is matched with and abuts against the lower cover plate of the upper end face of the shell 100, which helps reducing the entry of external impurities into the shell 100.
With reference to
The exemplary embodiments of the present application further provide a duct-type air conditioner. The duct-type air conditioner includes a filter screen and the housing according to any above embodiments of the present application. The filter screen is removably mounted on the filter screen mounting position 10b.
The batten 22 is used to press the sealing plate 21 to prevent an edge of the sealing plate 21 from being tilted. The filter screen is used to filter impurities such as dust and cotton wool in the air, so as to prevent the impurities such as dust and cotton wool from entering the duct-type air conditioner via the air return opening. The filter screen mounting position 10b is used to fix the filter screen, and the filter screen disassembling and assembling opening 10c communicated with the filter screen mounting position 10b is used to take and place the filter screen, that is, the filter screen dismounted from the filter screen mounting position 10b needs to be taken out from the filter screen disassembling and assembling opening 10c. Similarly, when mounting the filter screen, the filter screen needs to pass through the filter screen disassembling and assembling opening 10c before being placed on the filter screen mounting position 10b. The filter screen cover plate 23 is used to seal the filter screen disassembling and assembling opening 10c. Generally, it is only necessary to open the filter screen cover plate 23 when the filter screen needs to be disassembled and assembled.
In the related art, a filter screen cover plate of a duct-type air conditioner is fixed on a shell of the duct-type air conditioner by screws. When a filter screen needs to be removed, an operator needs to remove the screws fixing the filter screen cover plate with a tool to open the filter screen cover plate. Similarly, after the filter screen is mounted in the filter screen mounting position, the operator needs to use a tool to reinstall the previously removed screws to fix the filter screen cover plate on the shell, which is cumbersome and inconvenient to operate in a narrow space.
However, when the filter screen cover plate 23 according to the embodiments of the present application is in the closed state of sealing the filter screen disassembling and assembling opening 10c, the filter screen cover plate 23 and the batten 22 arranged on the sealing plate 21 are fixed by clamping, and the filter screen cover plate 23 does not need to be fixed by screws. Therefore, when disassembling and assembling the filter screen, the operator can open or close the filter screen cover plate 23 without using a tool, thereby the disassembling and assembling process of the filter screen is simplified and further the replacement of the filter screen is facilitated.
The opening of the shell 10 may be provided at a bottom, top or side of the shell 10.
The filter screen mounting position 10b may be set in a slot structure. When mounting the filter screen, the filter screen may be fixed by directly inserting into the slot. The filter screen mounting position 10b may also set be in other structural forms as long as the filter screen can be fixed.
The sealing plate 21 may be detachably connected to the shell 10. In an exemplary embodiment, the sealing plate 21 may be firmly connected to the shell 10 by a fastener such as a screw. However, the sealing plate 21 may also be non-detachably connected to the shell 10. In an exemplary embodiment, the sealing plate 21 may be fixedly connected to the shell 10 by ways of welding and bonding.
The sealing plate 21 may be an integral structure or a combined structure of multiple sub-plates. In an embodiment, referring to

The batten 22, the landing edge 21a and the shell 10 are firmly connected by the fastener, thereby the batten 22 can press the landing edge 21a, and the disassembling of the sealing plate 21 and the batten 22 is facilitated.
In an embodiment, referring to
When the filter screen cover plate 23 is in the closed state, the first elastic buckle 23b and the second elastic buckle 22a can be clamped together by elastic forces thereof. When the filter screen cover plate 23 needs to be opened, the operator only needs to apply a certain force to the filter screen cover plate 23, so that the first elastic buckle 23b can be separated from the second elastic buckle 22a, thereby facilitating the opening or closing of the filter screen cover plate 23.
A quantity of the first elastic buckle 23b may be one or more, and a quantity of the second elastic buckle 22a corresponds to the quantity of the first elastic buckle 23b. That is, each first elastic buckle 23b can be engaged with a corresponding second elastic buckle 22a.
