[0003] The embodiments of the present application provide an air-conditioning indoor unit and a HVAC system, which can reduce the number of installation personnel and labor costs by pre-mounting the panels.

[0004] In the first aspect, an embodiment of the present application provides an air-conditioning indoor unit, comprising a main body, a fixing, a panel and a limit member; the fixing member is connected to opposite sides of the main body; the panel is detachably connected to the main body, and an inspection port is provided on the panel at a position corresponding to the fixing member; the limit member is connected to the panel and corresponds to the position of the fixing member; wherein the limit member can be operated from the inspection port to switch between a combined state and a separated state with the fixing member, and in the combined state, the panel can be suspended below the main body through the connection between the limit member and the fixing member, and in the separated state, the panel can be separated from the main body.

[0005] This embodiment provides fixing parts and limit parts, and opens an inspection port on the panel, so that the staff can more conveniently and quickly perform the pre-fixing operation between the panel and the main body through the inspection port. After the pre-fixing, the staff can free their hands and perform the subsequent installation and fixing operations by one person, thereby reducing the number of installation personnel and labor costs.

[0006] In some embodiments of the present application, a limiter is disposed on the wall of the inspection opening to reduce interference between the limiter and other parts of the panel and to allow staff to more easily find the position of the limiter at the inspection opening.

[0007] In some embodiments of the present application, in the combined state, the limiter is buckled and connected with the fixing member, and in the separated state, the limiter and the fixing member are unfastened. The limiter can be directly connected with the fixing member under the manipulation of the staff, and the combination of the limiter and the fixing member can be completed without the use of external tools, thereby making it more convenient and quick to connect the limiter with the fixing member.

[0008] In some embodiments of the present application, the main body includes a casing, and the fixing member includes a first baffle connected to the casing, one end of the first baffle is connected to the casing, and the other end of the first baffle extends away from the casing, and the first baffle is used to engage with the limiting member to pre-fix the panel to the main body, and can limit the vertical movement of the panel.

[0009] In some embodiments of the present application, the fixing member further includes reinforcing ribs, which are connected to the bottom surface of the first baffle and the housing, and can improve the bearing strength of the first baffle.

[0010] In some embodiments of the present application, the fixing member further includes a second baffle, which is connected to the first baffle and extends upward, and the second baffle is used to prevent the limiting member from sliding on the first baffle. The second baffle can also limit the movement of the panel in the horizontal direction, thereby further making the connection between the limiting member and the fixing member more stable.

[0011] In some embodiments of the present application, the first baffle, the second baffle and the housing are an integrated structure to increase the strength of the fixing member.

[0012] In some embodiments of the present application, the panel further includes a mounting seat disposed on the wall of the inspection port, the position-limiting member includes a connecting portion and a hooking portion connected to each other, the connecting portion is rotatably connected to the mounting seat, and the hooking portion is used to engage with and release the fixing member. The staff can rotate the connecting portion so that the connecting portion drives the hooking portion to rotate to a position connected with the fixing portion, thereby realizing pre-fixation of the panel and the main body.

[0013] In some embodiments of the present application, when the stopper and the fixing member are buckled, the panel is connected to the main body, and there is a gap between the panel and the main body. The buckling of the stopper and the fixing member can play a role of pre-fixation. The panel is pre-fixed under the main body first, which can free the hands of the staff, so that the subsequent installation operation can be completed by the staff alone, thereby reducing the installation personnel and labor costs.

[0014] In some embodiments of the present application, the air conditioner indoor unit also includes a suspension part, which is connected to the side of the main body and is used to hang the main body.

[0016] The beneficial effects of the embodiment of the present application are as follows: the embodiment of the present application sets a fixing member and a limiting member, and at the same time opens an inspection port on the panel, and the positions of the fixing member and the limiting member correspond to the inspection port, so that the staff can more conveniently and quickly operate the fixing member and the limiting member through the inspection port, so that the fixing member and the limiting member can switch between the combined state and the separated state. During the installation process, when the panel needs to be pre-fixed with the main body, a single staff member can lift the panel, observe and operate through the inspection port, so that the fixing member and the limiting member are connected, and the fixing member and the limiting member are combined and suspended under the main body, and then other operations such as wiring are performed. After the connection operation is completed, the panel is completely fixed under the main body. Similarly, during the inspection process, when the panel needs to be disassembled, the fixing member and the limiting member can be operated through the inspection port to achieve the combination of the two, so that the panel is in a state of being suspended under the main body, which is convenient for releasing the connection structure and wiring structure between the panel and the main body, and then the panel is disassembled and separated. The panel is thus suspended below the main body by the connection of the limiter and the fixing part, thereby realizing pre-fixation between the panel and the main body. After the pre-fixation, the staff can free their hands and perform subsequent installation and fixing operations by one person, thereby reducing the number of installation personnel and labor costs.

[0033] In order to more clearly illustrate the technical solutions in the embodiments of the present application or related technologies, the following will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] The embodiment of the present application proposes a HVAC system (not shown in the figure), which includes but is not limited to air conditioning, multi-split units, heat pumps and other systems for heating or cooling, and the embodiment of the present application does not limit this.

[0035] Specifically, the indoor unit in the HVAC system may include an indoor unit body and an external panel. A control module is provided in the indoor unit body, and an air guide plate and a display component for displaying temperature and mode and other components are provided on the external panel. The air guide plate and the display component are electrically connected to the control module in the indoor unit body. Therefore, before the external panel is installed and fixed, the wiring operation between the external panel and the indoor unit body needs to be completed.

[0036] In order to complete the installation of the indoor unit in the HVAC system, the external panel needs to be lifted and fixed to the indoor unit body with screws and other fasteners. At this time, multiple installers need to cooperate with each other to complete the installation of the external panel, resulting in high labor costs for installation. Based on this, the embodiment of the present application provides an air conditioner indoor unit 1 (such as Figure 5 As shown), the panel 30 can be pre-mounted to reduce the installation personnel and labor costs.

[0037] See also Figure 1-Figure 2 An air conditioner indoor unit 1 according to an embodiment of the present application includes a main body 10 , a fixing member 20 , a panel 30 and a limiting member 40 .

[0038] The panel 30 is detachably connected to the main body 10. When the air conditioner indoor unit 1 is installed, the main body 10 can be installed into the wall or ceiling first, and then the panel 30 can be connected to the main body 10. The fixing parts 20 are connected to the opposite sides of the main body 10. The panel 30 is provided with an inspection opening 31 at the position corresponding to the fixing parts 20. The inspection opening 31 allows the staff to put their hands into the panel 30, so that the staff can hold the panel 30 with both hands and align the panel 30 with the main body 10 for subsequent installation operations.

[0039] The limit member 40 is connected to the panel 30 and corresponds to the position of the fixing member 20. The limit member 40 can be operated from the inspection port 31 so that the limit member 40 and the fixing member 20 can switch between a combined state and a separated state. In the combined state, the panel 30 can be suspended below the main body 10 through the connection between the limit member 40 and the fixing member 20 to pre-fix the panel 30 on the main body 10. In the separated state, the panel 30 can be separated from the main body 10.

[0040] Exemplarily, the limit member 40 can be a hook, which is rotatably connected to the panel 30. The staff can rotate the hook to make the hook hook and the fixing member 20 engage with each other, thereby making the limit member 40 and the fixing member 20 in a combined state; or, the limit member 40 can be a pin, and the fixing member 20 is provided with a socket, and the pin is slidably connected to the panel 30. The staff can turn the pin to make the pin slide and be inserted into the socket on the fixing member 20, thereby making the limit member 40 and the fixing member 20 in a combined state.

[0041] It should be noted that, in the embodiment of the present application, a fixing member 20 and a limiting member 40 are provided, and an inspection port 31 is opened on the panel 30. The positions of the fixing member 20 and the limiting member 40 correspond to the inspection port 31, so that the staff can more conveniently and quickly operate the fixing member 20 and the limiting member 40 through the inspection port 31, so that the fixing member 20 and the limiting member 40 can be switched between the combined state and the separated state. During the installation process, when the panel 30 needs to be pre-fixed with the main body 10, a single staff member can lift the panel 30, observe and operate through the inspection port 31, so that the limiting member 40 is connected with the fixing member 20, and the limiting member 40 is combined with the fixing member 20 and suspended under the main body 10, and then other operations such as wiring are performed. After the connection operation is completed, the panel 30 is completely fixed under the main body 10. Similarly, during the inspection process, when the panel 30 needs to be removed, the fixing member 20 and the stopper 40 can be operated through the inspection port 31 to achieve the combination of the two, so that the panel 30 is suspended below the main body 10, which is convenient for releasing the connection structure and wiring structure between the panel 30 and the main body 10, and then the panel 30 can be disassembled and separated. The fixing member 20 and the stopper 40 can provide temporary auxiliary fixing for the installation of the panel 30. After the panel 30 and the main body 10 are pre-fixed, the staff can perform subsequent operations without continuing to lift the panel 30, so that a single person can perform subsequent wiring and installation and fixing operations, thereby reducing the number of installation personnel and labor costs.

[0042] In some embodiments, a cover can be set at the position of the inspection port 31 to open or close the inspection port 31. When it is necessary to inspect the panel 30 or the main body 10, the inspection port 31 can be opened through the cover, and the interior of the panel 30 can be easily inspected from the inspection port 31, thereby improving the inspection efficiency.

[0043] See also Figure 1 In some embodiments of the present application, the air-conditioning indoor unit 1 also includes a suspension part 50, which is connected to the side of the main body 10 and is used to suspend the main body 10 so as to install the main body 10 on an external wall or plate. The suspension part 50 is arranged corresponding to the inspection port 31 so that the staff can adjust the position of the suspension part 50 and the main body 10 through the inspection port 31. At the same time, it is also beneficial to the subsequent maintenance operation of the air-conditioning indoor unit 1.

[0044] The limiting member 40 may be connected to the side wall of the panel 30 close to the inspection opening 31 . Of course, the limiting member 40 may also be connected to the wall of the inspection opening 31 on the panel 30 .

[0045] Please continue to see Figure 1In some embodiments of the present application, the limit member 40 is arranged on the wall of the inspection opening 31 to reduce the interference between the limit member 40 and other parts on the panel 30, and enables the staff to more conveniently feel the position of the limit member 40 when moving the limit member 40 through the inspection opening 31.

[0046] In some embodiments of the present application, in the combined state, the limiter 40 is buckled and connected with the fixing member 20, and in the separated state, the limiter 40 is unfastened from the fixing member 20. Specifically, in this embodiment, the limiter 40 and the fixing member 20 are combined by buckling, and the limiter 40 can be directly connected with the fixing member 20 under the manipulation of the staff, and the combination of the limiter 40 and the fixing member 20 can be completed without the use of external tools, thereby making it more convenient and quick to connect the limiter 40 with the fixing member 20.

[0047] Exemplarily, the limit member 40 can be a hook that is rotatably connected to the panel 30. The staff can rotate the hook to make the hook hook and the fixing member 20 hook and engage with each other, thereby making the limit member 40 and the fixing member 20 in a combined state; or, the limit member 40 can be a press-fit buckle, and the fixing member 20 can be a press-fit buckle position. The press-fit buckle is rotatably connected to the panel 30. The staff can rotate the press-fit buckle and apply force to the press-fit buckle to make the press-fit buckle engage with the press-fit buckle position, thereby making the limit member 40 and the fixing member 20 in a combined state.

[0048] See also Figure 2 In some embodiments of the present application, the panel 30 also includes a mounting seat 32 arranged on the wall of the inspection port 31, and the limiting member 40 includes a connecting portion 41 and a hook portion 42 that are connected to each other. The connecting portion 41 is rotatably connected to the mounting seat 32, and the hook portion 42 is used to engage and release the fixing member 20.

[0049] Specifically, the mounting seat 32 provides a foundation for the position-limiting member 40. When the connecting portion 41 rotates relative to the mounting seat 32, the position of the hook portion 42 relative to the fixing member 20 changes. The staff can rotate the connecting portion 41 to rotate the hook portion 42 to a position connected with the fixing portion to achieve pre-fixation of the panel 30 and the main body 10. The position-limiting member 40 can be made of metal material to ensure the strength of the position-limiting member 40.

[0050] Among them, Figure 2As shown, a through hole 321 and an avoidance groove 322 are provided on the mounting seat 32. The through hole 321 is connected to the avoidance groove 322. The connecting portion 41 is passed through the through hole 321 and can rotate relative to the mounting seat 32. The hook portion 42 is located in the avoidance groove 322. When the connecting portion 41 rotates relative to the mounting seat 32, the hook portion 42 can move in the avoidance groove 322. The avoidance groove 322 provides an avoidance space for the movement of the hook portion 42.

[0051] For further information, see Figure 3-Figure 4 The hook portion 42 has a hook hole 421. When the hook portion 42 is engaged with the fixing member 20, the fixing member 20 is located in the hook hole 421, which can not only more stably connect the panel 30 and the main body 10, but also reduce the positional offset between the panel 30 and the main body 10. Exemplarily, the hook portion 42 as a whole can be an inverted U-shaped structure. When the hook portion 42 is engaged with the fixing member 20, the fixing member 20 passes through the U-shaped structure of the hook portion 42, and the fixing member 20 contacts the U-shaped bottom of the hook portion 42, so that the hook portion 42 is engaged with the fixing member 20. The larger the width of the bottom of the U-shaped structure, the larger the contact area between the U-shaped structure and the fixing portion can be set, so that the engagement between the hook portion 42 and the fixing member 20 is more stable.

[0052] Please continue to see Figure 3-Figure 4 In some embodiments of the present application, when the stopper 40 is engaged with the fixing member 20, the panel 30 is connected to the main body 10, and there is a gap between the panel 30 and the main body 10, that is, the panel 30 and the main body 10 are not tightly connected at this time, and there is a first gap 12 between the panel 30 and the main body 10. The engagement of the stopper 40 and the fixing member 20 can play a role of pre-fixation. The panel 30 is first suspended below the main body 10. At this time, there is an operating space between the panel 30 and the main body 10, which is convenient for the staff to perform subsequent wiring and installation and fastening operations of the panel 30.

[0053] It should be noted that when the limit member 40 is engaged with the fixing member 20, the limit member 40 and the fixing member 20 are abutted against each other, and a first gap 12 is provided between the panel 30 and the main body 10. After the staff securely installs the panel 30 and the main body 10, the panel 30 and the main body 10 are tightly connected, and the limit member 40 and the fixing member 20 are separated. That is to say, the engagement of the limit member 40 and the fixing member 20 can pre-fix the panel 30 and the main body 10. After the subsequent installation operation of the panel 30 and the main body 10 is completed, the limit member 40 and the fixing member 20 are no longer needed to continue to fix.

[0054] See also Figure 5-Figure 6In some embodiments of the present application, the main body 10 includes a casing 11, and the fixing member 20 includes a first baffle 21 connected to the casing 11, one end of the first baffle 21 is connected to the casing 11, and the other end of the first baffle 21 extends in a direction away from the casing 11, and the first baffle 21 is used to engage with the limiting member 40. Specifically, when the limiting member 40 moves relative to the panel 30, until the limiting member 40 moves to the first baffle 21 and the limiting member 40 engages with the first baffle 21, the limiting member 40 is connected to the fixing member 20 to pre-fix the panel 30 to the main body 10.

[0055] Exemplarily, taking the limiting member 40 as a hook as an example, the first baffle 21 can be vertically arranged with respect to the casing 11. When the hook is hooked and engaged with the first baffle 21, the first baffle 21 can limit the vertical movement of the panel 30 to pre-fix the panel 30 under the main body 10; the first baffle 21 can also be tiltedly arranged on the casing 11, that is, one end of the first baffle 21 is connected to the casing 11, and the other end of the first baffle 21 extends upwardly and tilted away from the casing 11. At this time, when the hook is hooked and engaged with the first baffle 21, the hook will slide along the inclined surface of the first baffle 21 toward the direction close to the casing 11, so that the first baffle 21 will not only limit the vertical movement of the panel 30, but also limit the horizontal movement of the panel 30.

[0056] See also Figure 6 In some embodiments of the present application, the fixing member 20 further includes a reinforcing rib 23, which is connected to the bottom surface of the first baffle 21 and the housing 11 to improve the bearing strength of the first baffle 21, so that the first baffle 21 is more stable under stress. Among them, one or more reinforcing ribs 23 can be provided, and the number of reinforcing ribs 23 can be selected according to actual conditions, and is not limited here.

[0057] For further information, please see Figure 6 In some embodiments of the present application, the fixing member 20 further includes a second baffle 22 , which is connected to the first baffle 21 and extends upward, and the second baffle 22 is used to prevent the limiting member 40 from sliding on the first baffle 21 .

[0058] Specifically, the second baffle 22, the first baffle 21 and the housing 11 together form a snap-fitting space 24. When the limit member 40 moves into the snap-fitting space 24, the limit member 40 abuts against the first baffle 21. The first baffle 21 can limit the vertical movement of the panel 30, and the second baffle 22 can limit the horizontal movement of the panel 30, thereby making the connection between the limit member 40 and the fixing member 20 more stable and reducing the possibility of positional displacement between the limit member 40 and the fixing member 20.

[0059] In some embodiments, Figure 7-Figure 8As shown, the second baffle 22 has a connecting end 221 and a free end 222 that are arranged opposite to each other, the connecting end 221 is connected to the first baffle 21, and a protrusion 25 is arranged on the side of the second baffle 22 that is away from the housing 11, and the protrusion 25 has a guiding slope 251, and the guiding slope 251 extends obliquely from the free end 222 of the second baffle 22 to the connecting end 221, and the guiding slope 251 is used to guide the stopper 40. When the panel 30 is installed, the staff holds the panel with both hands. 30, and manually move the limiting member 40 to make the limiting member 40 move toward the direction of the fixing member 20. When the limiting member 40 is close to the second baffle plate 22, the guiding slope 251 can guide the limiting member 40 so that the limiting member 40 slides along the guiding slope 251 until the limiting member 40 slides to the top of the free end 222 of the second baffle plate 22, and then the limiting member 40 enters the snap-fitting space 24 formed by the second baffle plate 22, the first baffle plate 21 and the housing 11.

[0060] Furthermore, the first baffle 21 , the second baffle 22 and the housing 11 are an integrated structure, so that the first baffle 21 , the second baffle 22 and the housing 11 are integrated, the structure is tighter and more reliable without gaps, and the strength of the fixing member 20 is increased.
