Description

Technical Field

[0001] This application relates to the field of air conditioning system technology, and in particular to an indoor air conditioning unit. Background Technology

[0002] Air conditioner indoor units typically require an air filter at the air inlet to filter the air entering the unit. Flanges and guide structures are usually installed around the air inlet to allow for the pull-out installation of the filter. However, this design, with its complex structure and numerous parts, results in low production and assembly efficiency for the indoor unit. Utility Model Content

[0003] This application provides an indoor air conditioning unit that at least solves the technical problem of complex filter installation structure.

[0004] This application provides an indoor air conditioner unit. The indoor air conditioner unit includes a body, a frame, and a filter. The body has an air inlet. The frame is disposed on the body and surrounds the air inlet. The frame includes an inner side, and the inner side has a first limiting member spaced apart from the body. The first limiting member and the body together form a receiving space. The frame forms an insertion port communicating with the receiving space. The filter is housed in the receiving space, and the first limiting member and the body limit the filter along the thickness direction of the filter.

[0005] The indoor unit of this air conditioner, as described in this application, has a frame surrounding the air inlet to form an insertion port. A first limiting member, spaced apart from the unit body, is provided on the inner side of the frame. A receiving space for accommodating the filter is formed between the first limiting member and the unit body. The insertion port communicates with this receiving space, allowing the filter to be inserted into the receiving space through the insertion port on the frame. This simplifies the filter installation structure and improves the production and assembly efficiency of the indoor unit. Simultaneously, the first limiting member and the unit body limit the filter along its thickness direction, providing guidance during installation and reducing the risk of warping or deformation of the filter.

[0006] In some embodiments, there are multiple first limiting members, which are arranged at intervals along the circumference of the frame.

[0007] In this way, by arranging multiple first limiting components at intervals along the circumference of the frame, the filter screen is effectively limited in the direction surrounding the air inlet, preventing misalignment of the filter screen or deformation after long-term use.

[0008] In some embodiments, the first limiting member includes a screw, which is screwed onto the frame and passes through the inner side.

[0009] Thus, by screwing screws onto the frame and passing them through the inner side as the first limiting member, the assembly of the frame and the first limiting member is simplified, and the screws, being standard parts, facilitate mass production.

[0010] In some embodiments, the fuselage includes a top plate and a back plate connected to the top plate, the back plate forming an air inlet, and the inlet being located on the side of the frame away from the top plate.

[0011] In this way, an air inlet is formed through the back panel, and the inlet is located on the side of the frame away from the top panel, which makes it easy to install the filter screen from bottom to top.

[0012] In some embodiments, the frame includes a first member opposite the socket. The first member includes a first mounting portion, a second mounting portion, and a third mounting portion connected in sequence. The first mounting portion abuts against a top plate, the second mounting portion abuts against a back plate, and the third mounting portion protrudes from the back plate and has a portion of an inner side surface.

[0013] Thus, the first component abuts against the top plate via the first mounting part, the second mounting part abuts against the back plate, and the third mounting part protrudes from the back plate and has a partial inner side, thereby the first component can be stably mounted on the body and partially enclose the receiving space. The structure is simple and the assembly is relatively simple and efficient.

[0014] In some embodiments, the frame further includes a second member connected to the end of the first member. The second member includes a fourth mounting portion and a fifth mounting portion connected to each other. The fourth mounting portion abuts against the back plate, and the fifth mounting portion protrudes from the back plate. The first end of the fifth mounting portion is bent and fixedly connected to the third mounting portion. The fifth mounting portion has a portion of its inner side surface.

[0015] Thus, the second component abuts against the back plate via the fourth mounting part, the fifth mounting part protrudes from the back plate, the first end of the fifth mounting part is bent and fixedly connected to the third mounting part, and the fifth mounting part has a partial inner side, so that the second component can be stably connected to the first component and partially enclose the receiving space. The structure is simple and the installation is relatively easy.

[0016] In some embodiments, the frame further includes a third member and a fourth member, both of which are opposite to the first member. The third member and the fourth member are spaced apart to form a socket. The end of the third member is bent and fixedly connected to the second end of the fifth mounting portion. The fifth mounting portion has a partial inner side surface. The fourth member is mounted on the back plate.

[0017] Thus, by installing the fourth component onto the back panel, with the third and fourth components spaced apart to form an insertion slot, and the end of the third component bent and fixedly connected to the second end of the fifth mounting part, the assembly of each part of the frame is relatively simple, thus improving production efficiency.

[0018] In some embodiments, a second limiting member is provided on the inner side of the first component, and the second limiting member and the first limiting member are spaced apart along the height direction of the frame, with the filter screen located between the first limiting member and the second limiting member.

[0019] Thus, by setting the second limiting member and the first limiting member at intervals along the height direction of the frame, the filter screen is located between the first limiting member and the second limiting member, which facilitates the installation and positioning of the filter screen, strengthens the limiting of the filter screen during use, and prevents the filter screen from warping and deforming as much as possible.

[0020] In some embodiments, the back panel is provided with a guide surface that extends beyond the inner side, and the filter screen abuts against the guide surface.

[0021] Thus, with the guide surface extending beyond the inner surface, the filter screen abuts against the guide surface, thereby the guide surface and the first limiting member on the inner surface cooperate to guide and limit the filter screen during insertion, and prevent the filter screen from deforming as much as possible during long-term use.

[0022] In some implementations, the indoor unit of the air conditioner includes a fan housed within the unit body, with the filter located upstream of the fan.

[0023] In this way, by placing the filter screen upstream of the fan, the air entering the indoor unit of the air conditioner can be effectively filtered, thus achieving a purification effect.

[0038] Please see Figure 1 Firstly, this application provides an indoor air conditioning unit 100. The indoor air conditioning unit 100 can be a floor-standing air conditioner, a ducted air conditioner, etc. The indoor air conditioning unit 100 can introduce air through the air inlet 101 and blow airflow that has undergone heat exchange treatment into the room.

[0039] Please see Figures 2-4The indoor unit 100 of the air conditioner includes a body 10, a frame 20, and a filter 40. The body 10 is provided with an air inlet 101. The frame 20 is disposed on the body 10 and surrounds the air inlet 101. The frame 20 includes an inner side 201. The inner side 201 is provided with a first limiting member 21 spaced apart from the body 10. The first limiting member 21 and the body 10 together form a receiving space 210. The frame 20 forms an insertion port 202 communicating with the receiving space 210. The filter 40 is housed in the receiving space 210. The first limiting member 21 and the body 10 limit the filter 40 along the thickness direction of the filter 40.

[0040] In this embodiment, the indoor air conditioner unit 100 surrounds the air inlet 101 via a frame 20, forming an insertion port 202. A first limiting member 21, spaced apart from the unit body 10, is provided on the inner side 201 of the frame 20. A receiving space 210 for accommodating the filter screen 40 is formed between the first limiting member 21 and the unit body 10. The insertion port 202 communicates with the receiving space 210, allowing the filter screen 40 to be inserted into the receiving space 210 through the insertion port 202 on the frame 20. This simplifies the installation structure of the filter screen 40 and improves the production and assembly efficiency of the indoor air conditioner unit 100. Simultaneously, the first limiting member 21 and the unit body 10 limit the filter screen 40 along its thickness direction, thus providing a guiding effect during installation and reducing the risk of warping or deformation of the filter screen 40.

[0041] Specifically, the air inlet 101 penetrates one side wall of the fuselage 10 to connect the internal and external environments of the fuselage 10. The frame 20 matches the shape and size of the air inlet 101. The air inlet 101 can be formed into various shapes such as square, ellipse, and circle. This application only uses a square air inlet 101 as an example for illustration, and the frame 20 is a square frame structure. The socket 202 is formed on one side of the frame 20. For example, the socket 202 can be formed on the long side of the frame 20 and connect the two ends of that long side.

[0042] Optionally, the frame 20 protrudes from the wall of the body 10 surrounding the air inlet 101, with the inner side 201 of the frame 20 facing the air inlet 101. The periphery of the air inlet 101 can be the edge of the wall where the air inlet 101 is located. The direction in which the frame 20 protrudes from the wall of the body 10, that is, the height direction of the frame 20, is parallel to or coincides with the thickness direction of the filter screen 40.

[0043] The first limiting member 21 is spaced a certain distance from the wall of the body 10 where the frame 20 is located on the inner side 201 along the thickness direction of the filter screen 40. The first limiting member 21 is fixedly connected to the frame 20 and protrudes from the inner side 201 of the frame 20. The first limiting member 21 abuts against the side of the filter screen 40 opposite to the air inlet 101.

[0044] The filter 40 is laid in the accommodating space 210, that is, the space between the first limiting member 21 and the wall of the body 10 where the frame 20 is located. The filter 40 completely covers the air inlet 101 to effectively filter the air entering the body 10 from the air inlet 101. The filter 40 can be made of metal fibers, polymer fibers or composite materials woven into a fine mesh.

[0045] Please see Figure 3 and Figure 4 In some embodiments, there are multiple first limiting members 21, and the multiple first limiting members 21 are arranged at intervals along the circumference of the frame 20.

[0046] Thus, by arranging multiple first limiting members 21 at intervals along the circumference of the frame 20, the filter screen 40 is adequately limited in the direction surrounding the air inlet 101, preventing the filter screen 40 from being misaligned during installation or deformed after long-term use.

[0047] Specifically, the first limiting member 21 includes, but is not limited to, protrusions, ribs, screws 211, rivets, and other structures or components. The number of first limiting members 21 is multiple, meaning there are two or more first limiting members 21. For example, the number of first limiting members 21 can be three, five, six, or eight. Multiple first limiting members 21 can be arranged at equal or unequal intervals along the circumference of the frame 20. Multiple first limiting members 21 are arranged along the circumference of the frame 20 and surround the air inlet 101, abutting against the edge of the filter screen 40.

[0048] Optionally, the first limiting member 21 is distributed on the inner side surface 201 around the frame 20.

[0049] Please see Figures 2-4 In some embodiments, the first limiting member 21 includes a screw 211, which is screwed onto the frame 20 and passes through the inner side 201.

[0050] Thus, by screwing the screw 211 onto the frame 20 and passing it through the inner side 201 as the first limiting member 21, the assembly of the frame 20 and the first limiting member 21 is simplified, and the screw 211 is a standard part, which is convenient for mass production.

[0051] Specifically, the first limiting member 21 includes a screw 211, and a screw hole matching the first limiting member 21 is formed on the frame 20. The first limiting member 21 can be tightened in the screw hole to be fixedly installed on the frame 20. The thread length of the first limiting member 21 is greater than the wall thickness of the frame 20 so that the first limiting member 21 can protrude from the inner surface 201.

[0052] Please see Figure 3 and Figure 4In some embodiments, the body 10 includes a top plate 12 and a back plate 11 connected to the top plate 12. The back plate 11 has an air inlet 101 and an inlet 202 located on the side of the frame 20 away from the top plate 12.

[0053] Thus, an air inlet 101 is formed by the back panel 11, and the inlet 202 is located on the side of the frame 20 away from the top panel 12, which facilitates the installation of the filter 40 from bottom to top.

[0054] Specifically, the indoor unit 10 of the air conditioner is typically mounted on the ceiling or a wall near the ceiling. The indoor unit 100 can be installed in the indoor environment with the top panel 12 facing the ceiling and the back panel 11 facing the wall. The inlet 202 is located on the side of the frame 20 away from the top panel 12, that is, at the lower rear edge of the unit 10. With the inlet 202 facing away from the top panel 12, and the frame 20 vertically aligned with the back panel 11, the filter 40 is inserted into the receiving space 210 from bottom to top through the inlet 202, completing the installation.

[0055] Please see Figure 2 , Figure 4 and Figure 5 In some embodiments, the frame 20 includes a first member 23 opposite to the socket 202. The first member 23 includes a first mounting portion 231, a second mounting portion 232 and a third mounting portion 233 connected in sequence. The first mounting portion 231 abuts against the top plate 12, the second mounting portion 232 abuts against the back plate 11, and the third mounting portion 233 protrudes from the back plate 11. The third mounting portion 233 has a portion of the inner side surface 201.

[0056] Thus, the first component 23 abuts against the top plate 12 through the first mounting part, the second mounting part 232 abuts against the back plate 11, and the third mounting part protrudes from the back plate 11 and has a part of the inner side 201. As a result, the first component 23 can be stably installed on the fuselage 10 and partially enclose the accommodating space 210. The structure is simple and the assembly is relatively simple and efficient.

[0057] Specifically, the first component 23 is located on the upper side edge of the frame 20, and the insertion port 202 is formed on the lower side of the frame 20. The first mounting portion 231, the second mounting portion 232, and the third mounting portion 233 can all be sheet-like structures and extend along the length direction of the upper side edge of the frame 20. The first mounting portion 231, the second mounting portion 232, and the second mounting portion 232 can be connected as one piece; for example, the first mounting portion 231, the second mounting portion 232, and the second mounting portion 232 can be integrally formed by a stamping process.

[0058] Optionally, the first mounting portion 231 abuts against the edge where the top plate 12 and the back plate 11 connect, and the second mounting portion 232 abuts against the edge where the back plate 11 and the top plate 12 connect. The first mounting portion 231 and the second mounting portion 232 form an angle that matches the fuselage 10, so as to engage with the edge where the top plate 12 and the back plate 11 connect, and increase the area of ​​contact with the top plate 12 and the back plate 11.

[0059] The third mounting part 233 protrudes from the back plate 11 along the thickness direction of the filter screen 40. The inner side 201 of the third back plate 11 facing the air inlet 101 is formed and may be provided with a plurality of first limiting members 21.

[0060] Please see Figure 2 , Figure 4 and Figure 5 In some embodiments, the frame 20 further includes a second member 25 connected to the end of the first member 23. The second member 25 includes a fourth mounting portion 251 and a fifth mounting portion 252 connected to each other. The fourth mounting portion 251 abuts against the back plate 11, and the fifth mounting portion 252 protrudes from the back plate 11. The first end portion 2521 of the fifth mounting portion 252 is bent and fixedly connected to the third mounting portion 233. The fifth mounting portion 252 has a partial inner side surface 201.

[0061] Thus, the second component 25 abuts against the back plate 11 via the fourth mounting part 251, and the fifth mounting part 252 protrudes from the back plate 11. The first end 2521 of the fifth mounting part 252 is bent and fixedly connected to the third mounting part 233. The fifth mounting part 252 has a partial inner side 201, so that the second component 25 can be stably connected to the first component and partially enclose the receiving space 210. The structure is simple and the installation is relatively easy.

[0062] Specifically, the second component 25 is located on the left and / or right edge of the frame 20, and the end of the first component 23 is connected to the end of the second component 25, forming an angle between the first component 23 and the second component 25. Both the fourth mounting portion 251 and the fifth mounting portion 252 are sheet-like structures; the fourth mounting portion 251 is a narrow strip, and the fifth mounting portion 252 is a straight strip. The fourth mounting portion 251 can abut against the left or right edge of the back plate 11 and is substantially parallel to the back plate 11 to increase the contact area. The fourth mounting portion 251 and the fifth mounting portion 252 can be connected as a single unit.

[0063] The first end 2521 of the fifth mounting part 252 can be bent toward the air inlet 101. The first end 2521 can be fixedly connected to the third mounting part 233 by at least one of the following methods: welding, screwing, riveting, adhesive bonding, fastener connection, snap-fit ​​connection, etc. For example, the first end 2521 and the third mounting part 233 abut against each other and form overlapping screw holes. The first end 2521 and the third mounting part 233 are connected by fastening screws.

[0064] The fifth mounting part 252 protrudes from the back plate 11 along the thickness direction of the filter screen 40. The inner side 201 of the fifth back plate 11 facing the air inlet 101 is formed and may be provided with a plurality of first limiting members 21.

[0065] Please see Figure 2 , Figure 4 and Figure 5 In some embodiments, the frame 20 further includes a third member 26 and a fourth member 27, both of which are opposite to the first member 23. The third member 26 and the fourth member 27 are spaced apart to form a socket 202. The end of the third member 26 is bent and fixedly connected to the second end 2522 of the fifth mounting portion 252. The fifth mounting portion 252 has a partial inner side 201. The fourth member 27 is mounted on the back plate 11.

[0066] Thus, by installing the fourth component 27 onto the back plate 11, and the third component 26 and the fourth component 27 forming an interlocking slot 202, and bending the end of the third component 26 and fixing it to the second end 2522 of the fifth mounting part 252, the assembly of each part of the frame 20 is relatively simple, thus improving production efficiency.

[0067] Specifically, the third component 26 and the fourth component 27 are located on the lower edge of the frame 20. Both the third component 26 and the fourth component 27 may be sheet-like and elongated. The third component 26 may be approximately parallel to the top plate 12, and the fourth component 27 may be approximately parallel to the back plate 11. The side of the fourth component 27 closest to the air inlet 101 is opposite to and spaced from the third component 26 along the height direction of the frame 20. The inlet 202 is formed in the interval between the third component 26 and the fourth component 27 along the height direction of the frame 20, that is, along the thickness direction of the filter screen 40.

[0068] Optionally, the third component 26 and the second end 2522 have overlapping screw holes and are fixedly connected by fastening screws.

[0069] Optionally, the fourth component 27 is detachably connected to the back plate 11 by fastening screws or rivets.

[0070] Please see Figure 3-Figure 5In some embodiments, the inner side 201 of the first component 23 is provided with a second limiting member 24, the second limiting member 24 and the first limiting member 21 are spaced apart along the height direction of the frame 20, and the filter screen 40 is located between the first limiting member 21 and the second limiting member 24.

[0071] Thus, by setting the second limiting member 24 and the first limiting member 21 at intervals along the height direction of the frame 20, the filter screen 40 is located between the first limiting member 21 and the second limiting member 24, which facilitates the installation and positioning of the filter screen 40, and strengthens the limiting of the filter screen 40 during use, so as to prevent the filter screen 40 from warping and deforming as much as possible.

[0072] Specifically, the second limiting member 24 includes, but is not limited to, structures such as protrusions, ribs, and tongues. The second limiting member 24 can be fixedly connected to the first member 23. For example, the second limiting member 24 is a short, sheet-like structure and is formed inside the first member 23 by a stamping process.

[0073] The first limiting member 21 and the second limiting member 24 are spaced apart along the height direction of the frame 20, that is, along the thickness direction of the filter screen 40. The second limiting member 24 may be formed at the edge where the third mounting part 233 and the second mounting part 232 connect, and the second limiting member 24 is closer to the air inlet 101 than the first limiting member 21.

[0074] Optionally, two first limiting members 21 are provided at intervals along the length direction on the inner side 201 of the first member 23, and a second limiting member 24 is located between the two first limiting members 21 on the first member 23. Further, the two first limiting members 21 are respectively provided close to both ends of the first member 23 along the length direction, and the second limiting member 24 is located at or near the middle position of the first member 23 along the length direction.

[0075] Please see Figures 2-4 In some embodiments, the back plate 11 is provided with a guide surface 111 that extends beyond the inner side surface 201, and the filter screen 40 abuts against the guide surface 111.

[0076] Thus, with the guide surface 111 extending beyond the inner surface 201, the filter screen 40 abuts against the guide surface 111, thereby the guide surface 111 and the first limiting member 21 on the inner surface 201 cooperate to guide and limit the insertion of the filter screen 40, and prevent the filter screen 40 from deforming as much as possible during long-term use.

[0077] Specifically, the guide surface 111 is located on the left and / or right side of the back panel 11. The guide surface 111 on the left side of the back panel 11 extends beyond the inner side surface 201 of the second member 25 on the left, and the guide surface 111 on the right side of the back panel 11 extends beyond the inner side surface 201 of the second member 25 on the right. The guide surface 111 extends beyond the inner side surface 201 in the direction towards the air inlet 101 and extends in the direction opposite to the top plate 12 along the inlet 202, forming a narrow strip-shaped plane. The guide surface 111 and the first limiting member 21 protruding from the inner side surface 201 are opposite to and spaced apart from each other along the height direction of the frame 20.

[0078] The edge of the filter screen 40 on the side surface facing away from the first limiting member 21 in its own thickness direction abuts against the guide surface 111, so that the first limiting member 21 and the guide surface 111 respectively limit the filter screen 40 from both sides in the thickness direction, effectively preventing the edge of the filter screen 40 from curling.

[0079] Please see Figure 2 and Figure 3 In some embodiments, the indoor unit 100 of the air conditioner includes a fan 50 disposed within the body 10, and a filter 40 is located upstream of the fan 50.

[0080] Thus, by placing the filter 40 upstream of the fan 50, the air entering the indoor unit 100 of the air conditioner is effectively filtered, achieving a purification effect.

[0081] Specifically, the fan 50 can be a centrifugal fan 50, and the blades can be rotated by a motor to form and accelerate the airflow. The air inlet 101 is located upstream of the airflow formed when the fan 50 rotates, and the filter screen 40 covers the air inlet 101 to filter out impurities entering the air inlet 101.
