Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to an indoor unit and an air conditioner. Background Technology

[0002] Air conditioning and air conditioners are devices that use artificial means to regulate and control parameters such as temperature, humidity, and airflow of the air inside a building or structure.

[0003] It generally includes several major parts such as cold / heat source equipment, cold / heat medium distribution system, terminal devices, and other auxiliary equipment. The main components include the refrigeration unit, water pump, fan, and piping system. The terminal devices are responsible for utilizing the distributed cold / heat to specifically process the air conditions, ensuring that the air parameters of the target environment meet certain requirements.

[0004] The indoor unit of an air conditioner is the part of the air conditioning equipment placed indoors. The outer casing of existing indoor air conditioners is generally quite simple, and its function is limited to protecting the indoor unit and installing the filter. The filter installation part also uses a very simple snap-fit ​​method. Under the action of external force, the filter and the snap-fit ​​deform successively, so that the filter is snapped into the snap-fit, thus achieving installation.

[0005] Although production costs have been reduced, problems such as breakage of the snap-fit ​​structure, inconvenient installation, and inconvenient disassembly still exist during later maintenance due to the overly simple structure. Summary of the Invention

[0006] The problem solved by this invention is how to avoid problems such as the breakage of the snap-fit ​​structure, inconvenient installation, and inconvenient disassembly during maintenance.

[0007] To address the aforementioned problems, this invention provides an indoor unit, comprising: an indoor unit housing; a mounting plate disposed on the rear side of the indoor unit housing; a first support member disposed on the side of the mounting plate near the interior of the indoor unit housing; and a snap-fit ​​structure rotatably connected to the first support member and located on the side of the first support member away from the mounting plate; wherein, when the snap-fit ​​structure rotates relative to the first support member, it locks and unlocks with the filter.

[0008] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows: by setting a snap-fit ​​structure and rotating it with the first support member, the filter screen can be snapped and fixed by the relative rotation of the snap-fit ​​structure, which facilitates installation and disassembly and avoids damage to the snap-fit ​​structure during repeated maintenance.

[0009] In an optional embodiment, the rotation direction of the snap-fit ​​structure is always located in the same plane.

[0010] Understandably, by setting the rotation direction of the snap-fit ​​structure to always remain on the same plane, errors in snap-fit ​​locking with the filter screen are avoided. This ensures that when the filter screen is reinstalled after maintenance, its installation shape and position remain consistent with before installation, preventing long-term misalignment between the filter screen and the snap-fit ​​structure, which could cause excessive deformation and damage to both.

[0011] In an optional embodiment, the filter screen is disposed inside the indoor unit housing and located between the front side of the indoor unit housing and the first support member; wherein, one end of the filter screen is connected to the mounting plate, and the other end is locked and unlocked by the snap-fit ​​structure.

[0012] Understandably, the filter is positioned between the front of the indoor unit housing and the first support member, with one end connected to the mounting plate and the other end locked and unlocked by the snap-fit ​​structure. This ensures that the filter is installed in a safer environment, without putting extra stress on it. Furthermore, the removal process only reduces the stress on the filter, not increases it. The rotating connection design of the snap-fit ​​structure facilitates separation between the snap-fit ​​structure and one end of the filter, preventing excessive deformation and damage to the filter during disassembly.

[0013] In an optional embodiment, the snap-fit ​​structure includes: a rotating component rotatably connected to the first support member; a rotating body connected to the rotating component; and a snap-fit ​​portion disposed at the end of the rotating body away from the first support member; wherein, when the rotating body rotates back and forth around the first support member, the snap-fit ​​portion locks and unlocks with the filter screen.

[0014] Understandably, by setting the rotating component to be rotatably connected to the first support, the rotating body connected to the rotating component can rotate relative to the first support under the action of force. This allows the locking part on one side of the rotating body to lock and unlock the filter screen, improving the efficiency of filter screen installation and removal. It also avoids damage caused by excessive deformation during filter screen installation and removal in traditional locking structures, thus extending the service life.

[0015] In an optional embodiment, the snap-fit ​​structure further includes: a first elastic element connected between the snap-fit ​​portion and the rotating assembly; wherein the extension and retraction direction of the first elastic element is located in the same plane as the rotation direction of the rotating body, and the plane containing the rotation direction of the rotating body is perpendicular to the rotation axis of the rotating assembly.

[0016] Understandably, by setting a first elastic element between the snap-fit ​​part and the rotating assembly, and with the extension and retraction direction of the first elastic element and the rotation direction of the rotating body located on the same plane, and the plane containing the rotation direction of the rotating body being perpendicular to the rotation axis of the rotating assembly, the snap-fit ​​part connected to the rotating assembly via the first elastic element maintains its rotation direction within the same plane during rotation. This reduces errors during the installation process of the filter screen and the snap-fit ​​part, improves installation efficiency, and avoids damage to the surface of the snap-fit ​​part due to installation deviations, thus extending its service life.

[0017] In an optional embodiment, the snap-fit ​​structure further includes a self-locking part disposed between the snap-fit ​​part and the rotating assembly; wherein, when the snap-fit ​​part is locked with the filter screen, the self-locking part achieves self-locking.

[0018] Understandably, by setting a self-locking part between the snap-fit ​​part and the rotating component, the self-locking part achieves self-locking when the snap-fit ​​part is locked with the filter screen, thus preventing the snap-fit ​​part from detaching from the filter screen due to the air conditioner's own vibration, and improving the stability of the filter screen assembly.

[0019] In an optional embodiment, the self-locking part includes: a first locking member disposed on the side of the latching part near the rotating assembly; and a second locking member disposed on the rotating assembly and located between the first locking member and the rotating body; wherein, when the latching part is locked with the filter screen, the first locking member and the second locking member at least partially abut against each other.

[0020] Understandably, by setting a first locking member and a second locking member located between the first locking member and the rotating body, when the locking part is locked with the filter screen, the first locking member and the second locking member at least partially abut against each other, so as to lock the rotation direction of the locking part, prevent the locking part from rotating out of the filter screen, and further increase the stability of the installation.

[0021] In an optional embodiment, the rotating body includes: an operating member connected to the snap-fit ​​portion; and a second elastic member connected between the operating member and the rotating assembly.

[0022] Understandably, the connection between the operating component and the locking part allows installation and maintenance personnel to easily lock and unlock the filter by holding the operating component and rotating the locking part, thus facilitating disassembly and assembly. At the same time, the second elastic element between the operating component and the rotating component increases the elastic strength of the connection between them, making it less likely that the locking part will detach from the filter under the vibration of the air conditioner itself after the first and second locking elements abut against each other and lock.

[0023] In an optional embodiment, the latching part includes: a first latching member; a second latching member, one end of which is connected to the first latching member, and the other end of which forms a latching interface with the first latching member; wherein the connection between the second latching member and the first latching member is connected to the operating member.

[0024] Understandably, by setting up a connection at one end of the first card connector, the second card connector, and the operating component, a card interface is formed between the first card connector and the second card connector. This allows the operating component to rotate the card interface formed between the first card connector and the second card connector, thereby locking and unlocking the filter and improving the efficiency of disassembly and assembly.

[0025] In an optional embodiment, the system further includes: a louver structure disposed within the indoor unit housing and located between the air outlet of the indoor unit and the filter; the louver structure includes: a connecting frame, with both ends fixedly connected to the upper and lower sides of the indoor unit housing respectively; a plastic strip, with both ends elastically connected to the upper and lower sides of the indoor unit housing respectively, and located between the connecting frame and the air outlet; and multiple louver bodies located at the air outlet and rotatably connected to the plastic strip; wherein the multiple louver bodies are equally spaced, and the end closest to the filter is rotatably connected to the connecting frame.

[0026] Understandably, by setting up the plastic strip, its soft structure creates a buffer gap when the louver body is moved, thereby buffering the force when the louver structure is subjected to force, reducing the probability of structural component failure, reducing the chance of structural component replacement, and further improving the environmental protection effect of the present invention. At the same time, the connecting frame fixedly set on the upper and lower sides inside the indoor unit housing can stabilize the reference point when the louver body rotates, making the rotation of the louver body more stable.

[0027] This invention also provides an air conditioner, including the indoor unit described in any of the above embodiments.

[0028] The present invention has the following beneficial effects:

[0029] 1) By setting a snap-fit ​​structure and rotating it with the first support member, the filter screen can be snapped and fixed by the relative rotation of the snap-fit ​​structure, which facilitates installation and disassembly and avoids damage to the snap-fit ​​structure during repeated maintenance.

[0030] 2) By setting the rotation direction of the snap-fit ​​structure to always remain on the same plane, errors in snap-fit ​​locking with the filter screen are avoided. This ensures that when the filter screen is reinstalled after maintenance, its installation shape and position remain consistent with before installation, preventing long-term misalignment between the filter screen and the snap-fit ​​structure, which could cause the filter screen and the snap-fit ​​structure to remain in an excessively deformed state for a long time and thus be damaged.

[0031] 3) The filter screen is positioned between the front of the indoor unit housing and the first support member, with one end connected to the mounting plate and the other end locked and unlocked by the snap-fit ​​structure. This ensures that the filter screen is installed in a safer environment, without causing additional stress on the filter screen. During removal, the stress on the filter screen will only be reduced, not increased. In addition, the rotating connection design of the snap-fit ​​structure facilitates the separation of the snap-fit ​​structure from one end of the filter screen, preventing the filter screen from being damaged due to excessive deformation during disassembly.

[0032] 4) By setting the rotating component to be rotatably connected to the first support, the rotating body connected to the rotating component can rotate relative to the first support under the action of force. This allows the locking part on one side of the rotating body to lock and unlock the filter screen, improving the efficiency of filter screen installation and removal. It also avoids damage caused by excessive deformation during filter screen installation and removal in traditional locking structures, thus extending the service life.

[0033] 5) By setting the plastic strip, its soft structure provides a buffer gap when the louver body is moved, thereby buffering the force when the louver structure is subjected to force, reducing the probability of structural component failure, reducing the chance of structural component replacement, and further improving the environmental protection effect of the present invention. At the same time, the connecting frame fixedly connected to the upper and lower sides inside the indoor unit housing can stabilize the reference point when the louver body rotates, making the rotation of the louver body more stable.

Detailed Implementation

[0039] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] [First Embodiment]

[0041] See Figure 1 and Figure 2 This invention provides an indoor unit 100, including: an indoor unit housing 1, a first support member 6, a mounting plate 4, and a snap-fit ​​structure 7.

[0042] Specifically, the mounting plate 4 is located on the rear side of the indoor unit housing 1; the first support member 6 is located on the side of the mounting plate 4 near the interior of the indoor unit housing 1; the snap-fit ​​structure 7 is rotatably connected to the first support member 6 and is located on the side of the first support member 6 away from the mounting plate 4; wherein, when the snap-fit ​​structure 7 rotates relative to the first support member 6, it locks and unlocks with the filter screen 8.

[0043] By setting the snap-fit ​​structure 7 to be rotatably connected to the first support member 6, the filter screen 8 can be snapped and fixed by the relative rotation of the snap-fit ​​structure 7, which facilitates installation and disassembly and avoids damage to the snap-fit ​​structure 7 during repeated maintenance.

[0044] Furthermore, the indoor unit 100 also includes: an indoor unit body 5, which is mounted on the mounting plate 4 and located inside the indoor unit housing 1, with first support members 6 respectively provided on both sides of the indoor unit body 5.

[0045] The present invention uses the mounting plate 4 to install the indoor unit body 5, so that there is no connection between the overall structure of the indoor unit housing 1 and the indoor unit body 5. Therefore, when the user repairs the indoor unit body 5, he only needs to remove the indoor unit housing 1 from the mounting plate 4. Furthermore, the indoor unit housing 1 is an integral piece, which provides a large maintenance space for the indoor unit body 5 after removal, making maintenance convenient.

[0046] Furthermore, an air outlet 12 is provided on the front side of the indoor unit casing 1, and a screen 2 is installed on the top. This is for air circulation, thereby regulating the indoor air.

[0047] Furthermore, the rotation direction of the snap-fit ​​structure 7 is always located in the same plane.

[0048] By ensuring that the rotation direction of the snap-fit ​​structure 7 is always kept on the same plane, errors in snap-fit ​​locking with the filter screen 8 are avoided. This ensures that when the filter screen 8 is reinstalled after maintenance, its installation shape and position remain consistent with those before installation. This prevents the filter screen 8 and the snap-fit ​​structure 7 from being misaligned for a long time, which could cause the filter screen 8 and the snap-fit ​​structure 7 to remain in an excessively deformed state for an extended period and become damaged.

[0049] Furthermore, the filter 8 is located inside the indoor unit housing 1 and between the front side of the indoor unit housing 1 and the first support member 6; wherein, one end of the filter 8 is connected to the mounting plate 4, and the other end is locked and unlocked by the snap-fit ​​structure 7.

[0050] By positioning the filter 8 between the front of the indoor unit housing 1 and the first support member 6, with one end connected to the mounting plate 4 and the other end locked and unlocked by the snap-fit ​​structure 7, the installation position of the filter 8 is in a safer installation environment, without causing additional stress on the filter 8. Furthermore, during removal, the stress on the filter 8 is reduced rather than increased. In addition, the rotating connection design of the snap-fit ​​structure 7 facilitates the separation of the snap-fit ​​structure 7 from one end of the filter 8, preventing the filter 8 from being damaged due to excessive deformation during disassembly.

[0051] Further, see Figure 3 The snap-fit ​​structure 7 includes: a rotating assembly 60, a rotating body 80, and a snap-fit ​​part 70.

[0052] Specifically, the rotating assembly 60 is rotatably connected to the first support member 6; the rotating body 80 is connected to the rotating assembly 60; the locking part 70 is located at the end of the rotating body 80 away from the first support member 6; wherein, when the rotating body 80 rotates back and forth around the first support member 6, the locking part 70 and the filter screen 8 are locked and unlocked.

[0053] By rotatably connecting the rotating component 60 to the first support member 6, the rotating body 80 connected to the rotating component 60 can rotate relative to the first support member 6 under the action of force. This rotation of the rotating body 80 allows the locking part 70 on one side of the rotating body 80 to lock and unlock with the filter screen 8, improving the efficiency of filter screen 8 installation and removal, avoiding damage caused by excessive deformation during the installation and removal of the filter screen 8 in the traditional locking structure 7, and extending its service life.

[0054] Further, see Figure 3 The rotating assembly 60 includes a connecting shaft 71 and a rotating seat 72.

[0055] Specifically, the two ends of the connecting shaft 71 are connected to the first support members 6 respectively provided on both sides of the indoor unit body 5, and the rotating seat 72 is rotatably connected to the rotating shaft;

[0056] Furthermore, the snap-fit ​​structure 7 also includes: a first elastic member 73, connected between the snap-fit ​​part 70 and the rotating seat 72; wherein the extension and retraction direction of the first elastic member 73 is located on the same plane as the rotation direction of the rotating body 80, and the plane where the rotation direction of the rotating body 80 is located is perpendicular to the rotation axis of the rotating assembly 60.

[0057] By providing a first elastic element 73 between the snap-fit ​​part 70 and the rotating seat 72, and the extension and retraction direction of the first elastic element 73 being located in the same plane as the rotation direction of the rotating body 80, and the plane where the rotation direction of the rotating body 80 is located being perpendicular to the rotation axis of the rotating assembly 60, the snap-fit ​​part 70 connected to the rotating assembly 60 through the first elastic element 73 is kept in the same plane during rotation. This reduces the error in the installation process of the filter screen 8 and the snap-fit ​​part 70, improves the installation efficiency, and avoids damage to the surface of the snap-fit ​​part 70 due to installation deviation, thus extending its service life.

[0058] For example, the first elastic element 73 can be an elastic element with an equal width surface, such as a curved elastic sheet with an equal width surface of a sheet structure. Because it is limited by the sheet structure, its swing direction can only exist in a single plane, thereby causing the rotation direction of the locking part 70 to always remain in the same plane, thereby reducing the error in the process of fitting and installing the filter screen 8 and the locking part 70. This will not be elaborated further here.

[0059] Furthermore, the snap-fit ​​structure 7 also includes a self-locking part 90, which is disposed between the snap-fit ​​part 70 and the rotating seat 72; wherein, when the snap-fit ​​part 70 is locked with the filter screen 8, the self-locking part 90 achieves self-locking.

[0060] By providing a self-locking part 90 between the snap-fit ​​part 70 and the rotating seat 72, the self-locking part 90 achieves self-locking when the snap-fit ​​part 70 and the filter screen 8 are locked, thus preventing the snap-fit ​​part 70 from disengaging from the filter screen 8 due to the air conditioner's own vibration, and improving the stability of the filter screen 8 assembly.

[0061] Furthermore, the self-locking part 90 includes: a first locking member 710 and a second locking member 79.

[0062] Specifically, the first locking member 710 is located on the side of the latching part 70 near the rotating seat 72; the second locking member 79 is located on the rotating seat 72 and between the first locking member 710 and the rotating body 80; wherein, when the latching part 70 is locked with the filter screen 8, the first locking member 710 and the second locking member 79 at least partially abut against each other.

[0063] By setting a first locking member 710 and a second locking member 79 located between the first locking member 710 and the rotating body 80, when the locking part 70 is locked with the filter screen 8, the first locking member 710 and the second locking member 79 at least partially abut against each other, so as to lock the rotation direction of the locking part 70, prevent the locking part 70 from rotating out of the filter screen 8, and further increase the stability of the installation.

[0064] For example, the first locking member 710 and the second locking member 79 mentioned above can be baffles that protrude from the snap-fit ​​portion 70 and the rotating assembly 60, respectively, which will not be described in detail here.

[0065] Furthermore, the rotating body 80 includes: an operating element 77 and a second elastic element 78.

[0066] Specifically, the operating member 77 is connected to the locking part 70; the second elastic member 78 is connected between the operating member 77 and the rotating seat 72.

[0067] By connecting the operating component 77 to the locking part 70, installation and maintenance personnel can easily lock and unlock the filter screen 8 by holding the operating component 77 and rotating the locking part 70, which facilitates disassembly and assembly. At the same time, a second elastic element 78 is provided between the operating component 77 and the rotating seat 72, which increases the elastic strength of the connection between the operating component 77 and the rotating assembly 60. This makes it less likely that the locking part 70 will detach from the filter screen 8 due to the vibration of the air conditioner itself after the first locking element 710 and the second locking element 79 are locked together.

[0068] For example, the second elastic element 78 can be an elastic element with elasticity, such as a spring, elastic sheet, elastic rod, or a connecting element made of rubber material with deformation characteristics, which will not be described in detail here.

[0069] Furthermore, the latching part 70 includes: a first latching member 75 and a second latching member 74.

[0070] Specifically, one end of the second card connector 74 is connected to the first card connector 75, and the other end forms a card interface with the first card connector 75; wherein, the connection between the second card connector 74 and the first card connector 75 is connected to the operating component 77.

[0071] By connecting one end of the first card connector 75, the second card connector 74, and the operating component 77, a card interface is formed between the first card connector 75 and the second card connector 74. This allows the operating component 77 to rotate the card interface formed between the first card connector 75 and the second card connector 74, thereby locking and unlocking the filter screen 8 and improving the efficiency of disassembly and assembly.

[0072] Furthermore, the snap-fit ​​portion 70 also includes: a third elastic member 76;

[0073] Specifically, the first snap-fit ​​member 75 is bent toward the rotating assembly 60 at the end away from the operating member 77, and the third elastic member 76 is connected to the second snap-fit ​​member 74 and is located at the snap-fit ​​interface; wherein, when the snap-fit ​​part 70 is locked with the filter screen 8, the bent part of the first snap-fit ​​member 75 cooperates with the third elastic member 76 to fit against the two opposite sides of the filter screen 8.

[0074] By setting a third elastic element 76, and cooperating with the first snap-fit ​​element 75 at the bend of the end away from the operating element 77 towards the rotating assembly 60, the two opposite sides of the filter screen 8 are fitted and locked, making the snap-fit ​​part 70 and the filter screen 8 more securely installed.

[0075] For example, the third elastic element 76 can be an elastic element with elasticity, such as a spring or an elastic sheet, which will not be elaborated here.

[0076] Further, see Figure 2 It also includes: a louver structure 3, which is installed inside the indoor unit housing 1 and located between the air outlet 12 and the filter 8 of the indoor unit 100; the louver structure 3 includes: a connecting frame 37, a plastic strip 31 and multiple louver bodies 36.

[0077] Specifically, the two ends of the connecting bracket 37 are fixedly connected to the upper and lower sides of the indoor unit housing 1, respectively; the two ends of the plastic strip 31 are elastically connected to the upper and lower sides of the indoor unit housing 1, respectively; and are located between the connecting bracket 37 and the air outlet 12; multiple louver bodies 36 are located at the air outlet 12 and are rotatably connected to the plastic strip 31; wherein, the multiple louver bodies 36 are equally spaced, and the end near the filter 8 is rotatably connected to the connecting bracket 37.

[0078] By setting the plastic strip 31, its soft structure provides a buffer gap when the louver body 36 is moved, thereby allowing the louver structure 3 to buffer the force when subjected to force, reducing the probability of structural component failure and the need for structural component replacement, and further improving the environmental protection effect of the present invention. At the same time, the connecting bracket 37 fixedly connected to the upper and lower sides inside the indoor unit housing 1 can stabilize the reference point when the louver body 36 rotates, making the rotation of the louver body 36 more stable.

[0079] Furthermore, one end of the plastic strip 31 is connected to the tension spring 34 provided on the upper side of the indoor unit housing 1, and the other end is connected to the winch motor 35 provided on the lower side of the indoor unit housing 1.

[0080] Alternatively, one end of the plastic strip 31 is fixedly connected to the upper side of the indoor unit housing 1, and the other end is connected to the telescopic motor installed on the lower side of the indoor unit housing 1 via a connecting rope.

[0081] Furthermore, the louver structure 3 also includes: a groove 32 and a limiting seat 33.

[0082] Specifically, the slide groove 32 is located at both ends of the plastic strip 31, and one end of the limiting seat 33 is fixedly connected to the inside of the indoor unit housing 1, while the other end is slidably connected to the slide groove 32.
