Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to an indoor unit and an air conditioner. Background Technology

[0002] After prolonged use, air conditioners accumulate dust, bacteria, and mold on components such as filters and evaporators. This not only affects cooling and heating efficiency and increases power consumption, but may also spread odors through the airflow and cause respiratory discomfort. Therefore, it is necessary to clean the air conditioner regularly.

[0003] However, under the existing air conditioning structure, the panel and filter need to be removed and the filter needs to be cleaned separately, which is extremely inconvenient. At the same time, when cleaning the evaporator, the cleaning water is easy to drip onto other parts of the indoor unit, contaminating them and affecting the cleaning effect. Utility Model Content

[0004] The main objective of this utility model embodiment is to provide an indoor unit and air conditioner, aiming to improve the technical problem of cumbersome air conditioner cleaning steps in the prior art.

[0005] An embodiment of this utility model provides an indoor unit, comprising: Cross-flow fan; A heat exchanger is arranged around the cross-flow fan; A baffle is disposed between the heat exchanger and the cross-flow fan. The baffle can switch between a contracted state and an extended state. When the baffle is in the contracted state, its orthogonal projection on the cross-flow fan covers a small portion of the cross-flow fan. When the baffle is in the extended state, its orthogonal projection on the cross-flow fan completely covers the cross-flow fan.

[0006] In some embodiments, the baffle member can be expanded from the contracted state to the expanded state under the action of an external force, and return to the contracted state after the external force is removed; Along the width direction of the indoor unit, the baffle has a first end and a second end. When the baffle is in the retracted state, the first end is in the first position and the second end is in the second position. When the baffle is in the extended state, the first end moves to the third position and the second end moves to the fourth position.

[0007] In some embodiments of this utility model, the indoor unit further includes a middle frame, and the heat exchanger, the cross-flow fan and the baffle are all fixed inside the middle frame. The middle frame is provided with a third limiting part and a fourth limiting part. The third limiting part is used to connect with the first end and fix the first end at the third position, and the fourth limiting part is used to connect with the second end and fix the second end at the fourth position.

[0008] In some embodiments of this utility model, the middle frame is further provided with a first limiting part and a second limiting part. The first limiting part is used to connect with the first end and fix the first end in the first position, and the second limiting part is used to connect with the second end and fix the second end in the second position.

[0009] In some embodiments of this utility model, mounting grooves are respectively provided at both ends of the middle frame, and the side of the baffle is installed in the mounting groove, wherein one of the mounting grooves connects the third limiting part, the first limiting part, the second limiting part and the fourth limiting part.

[0010] In some embodiments of this utility model, the indoor unit further includes a filter screen, which is disposed on the side of the heat exchanger away from the cross-flow fan and surrounding the heat exchanger.

[0011] In some embodiments of this utility model, the indoor unit further includes a spray mechanism, which is disposed on the side of the heat exchanger away from the cross-flow fan, and is used to spray cleaning water onto the heat exchanger.

[0012] In some embodiments of this utility model, the spraying mechanism includes a water tank, a water pump, and at least one spraying rod. The water pump is connected to the water tank, one end of the spraying rod is connected to the water pump, the spraying rod is arranged along the length of the indoor unit, and the spraying rod has multiple spray nozzles.

[0013] In some embodiments of this utility model, the spraying mechanism further includes a drive motor, which is connected to the end of the spraying rod away from the water pump, and the drive motor is used to drive the spraying rod to rotate.

[0014] In some embodiments of this utility model, this utility model also provides an air conditioner, which includes the above-described indoor unit.

[0015] An embodiment of this utility model provides an indoor unit and an air conditioner. The indoor unit has a retractable and deployable baffle between the heat exchanger and the cross-flow fan. When the baffle is retracted, the indoor unit operates normally. When the baffle is deployed, it blocks the cross-flow fan, allowing direct rinsing of components such as the filter and heat exchanger. This avoids water droplets falling on other components and affecting the cleaning effect, and eliminates the need to disassemble the filter, simplifying the cleaning process.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0023] like Figures 1-5 As shown, this utility model provides an indoor unit, including a cross-flow fan 100, a heat exchanger 200, and a baffle 300. The heat exchanger 200 is arranged around the cross-flow fan 100, and the baffle 300 is arranged between the heat exchanger 200 and the cross-flow fan 100. The baffle 300 can switch between a retracted state and an extended state. When the baffle 300 is in the retracted state, the orthographic projection of the baffle 300 on the cross-flow fan 100 covers a small area of ​​the cross-flow fan 100. When the baffle 300 is in the extended state, the orthographic projection of the baffle 300 on the cross-flow fan 100 completely covers the cross-flow fan 100.

[0024] It should be noted that when the baffle 300 is in the retracted state, its area is small, covering only a small part of the cross-flow fan 100, allowing the heat exchange duct between the heat exchanger 200 and the cross-flow fan 100 to work normally. When the baffle 300 is in the extended state, its area increases, completely blocking the cross-flow fan 100. Water droplets from cleaning the heat exchanger 200 fall onto the baffle 300 and flow away from both sides of the cross-flow fan 100 along the baffle 300.

[0025] Understandably, the indoor unit has a retractable and deployable baffle 300 between the heat exchanger 200 and the cross-flow fan 100. When the baffle 300 is retracted, the indoor unit operates normally. When the baffle 300 is deployed, it blocks the cross-flow fan 100, allowing direct rinsing of components such as the filter 500 and the heat exchanger 200. This prevents cleaning water from dripping onto other components and affecting the cleaning effect. There is no need to disassemble the filter 500, simplifying the cleaning process.

[0026] Generally, the indoor unit also includes a middle frame 12 and a base 11. The middle frame 12 is installed on the base 11, and a water receiving tray is provided on the base 11. The heat exchanger 200, the cross-flow fan 100, and the baffle 300 are all fixed inside the middle frame 12. Along the length of the indoor unit, the baffle 300 has a first side and a second side, which are respectively connected to the two ends of the middle frame 12. When the baffle 300 is in the unfolded state, the cleaning water of the heat exchanger 200 drips onto the baffle 300 and flows along the baffle 300 to the water receiving tray for discharge.

[0027] In some embodiments, the baffle 300 is positioned close to the heat exchanger 200 to ensure that the dripping distance of the cleaning water between the heat exchanger 200 and the baffle 300 is small, thus avoiding dripping and splashing.

[0028] In some embodiments, the baffle member 300 can be extended from a retracted state to an extended state under the action of an external force, and return to the retracted state after the external force is removed; along the width direction of the indoor unit, the baffle member 300 has a first end 310 and a second end 320. When the baffle member 300 is in the retracted state, the first end 310 is in a first position and the second end 320 is in a second position. When the baffle member 300 is in the extended state, the first end 310 moves to a third position and the second end 320 moves to a fourth position.

[0029] It should be noted that the baffle 300 is an elastic baffle, which can be made of high-temperature resistant silicone material. It can stretch under tension and return to its original shape after the tension is removed. Therefore, the baffle 300 can be unfolded into an unfolded shape when cleaning is required, and can be in a contracted shape when cleaning is not required, so as to ensure that the airflow between the heat exchanger 200 and the cross-flow fan 100 can flow normally for heat exchange.

[0030] That is, the first end 310 of the baffle member 300 can be pulled from the first position to the third position under the action of external force, and reset to the first position after the external force is removed; the second end 320 of the baffle member 300 can be pulled from the second position to the fourth position under the action of external force, and reset to the second position after the external force is removed.

[0031] In some embodiments, since the heat exchanger 200 is typically a zigzag structure, when the baffle member 300 expands from a contracted state to an expanded state, the first end 310 and the second end 320 move in two different directions.

[0032] In some embodiments, the indoor unit further includes a middle frame 12, and the heat exchanger 200, the cross-flow fan 100 and the baffle 300 are all fixed inside the middle frame 12. The middle frame 12 is provided with a third limiting part 303 and a fourth limiting part 304. The third limiting part 303 is used to connect with the first end 310 and fix the first end 310 in a third position, and the fourth limiting part 304 is used to connect with the second end 320 and fix the second end 320 in a fourth position.

[0033] It is understandable that when the baffle 300 needs to be kept in the unfolded state, the first end 310 and the second end 320 need to be kept in the third position and the fourth position respectively. That is, the first end 310 is connected to the third limiting part 303 when it moves to the third position and is fixed in the third position by the third limiting part 303, and the second end 320 is connected to the fourth limiting part 304 when it moves to the fourth position and is fixed in the fourth position by the fourth limiting part 304, so that the baffle 300 is kept in the unfolded state.

[0034] It should be noted that the third limiting part 303 and the first end 310, and the fourth limiting part 304 and the second end 320 are detachably connected, so that the first end 310 can be separated from the third limiting part 303 and the second end 320 can be separated from the fourth limiting part 304, so that the baffle member 300 can return to the retracted form; for example, the first end 310 and the third limiting part 303, and the second end 320 and the fourth limiting part 304 are snap-fit ​​connected.

[0035] Furthermore, in some embodiments, the middle frame 12 is also provided with a first limiting part 301 and a second limiting part 302. The first limiting part 301 is used to connect with the first end 310 and fix the first end 310 in a first position, and the second limiting part 302 is used to connect with the second end 320 and fix the second end 320 in a second position.

[0036] It is understandable that, referring to the above-mentioned third limiting part 303 and fourth limiting part 304, the first limiting part 301 and the second limiting part 302 are respectively used to fix the first end 310 in the first position and fix the second end 320 in the second position. On the one hand, the baffle 300 can be kept in a retracted form, and on the other hand, the first end 310 and the second end 320 can be prevented from shaking due to airflow when the cross-flow fan 100 and the heat exchanger 200 are working normally, thus avoiding noise.

[0037] It should be noted that the first limiting part 301 and the first end 310, and the second limiting part 302 and the second end 320 are all detachably connected, so that the first end 310 can be separated from the first limiting part 301 and the second end 320 can be separated from the second limiting part 302, so that the baffle member 300 can return to the retracted form; for example, the first end 310 and the first limiting part 301, and the second end 320 and the second limiting part 302 are all snap-fit ​​connected.

[0038] Furthermore, in some implementations, mounting grooves are provided at both ends of the middle frame 12, and the side of the baffle 300 is installed in the mounting groove, one of which connects the third limiting part 303, the first limiting part 301, the second limiting part 302 and the fourth limiting part 304.

[0039] It should be noted that the first and second sides of the baffle 300 are respectively connected to the corresponding mounting slots. The mounting slots are generally through-hole structures set on the middle frame 12, and the side of the baffle passes through the through-hole structure. One of the mounting slots connects to four limiting parts for adjusting the shape of the baffle 300. When it is necessary to move the first end 310 from the first limiting part 301 to the second limiting part 302, the first end 310 is taken out from the mounting slot, pulled to the third limiting part 303, and reinstalled in the third limiting part 303. The other side of the baffle 300 then moves in the mounting slot.

[0040] For example, the first limiting part 301, the second limiting part 302, the third limiting part 303 and the fourth limiting part 304 are all cross-shaped through holes, and the first end 310 and the second end 320 are both cross-shaped structures. By moving the cross-shaped structure from one cross-shaped through hole to another cross-shaped through hole, the position change and fixation of the first end 310 or the second end 320 can be achieved.

[0041] In some embodiments, the indoor unit also includes a housing, which is installed on the outside of the middle frame 12. An operation window and a cover are provided on the side of the housing near the first limiting part 301. The cover is placed on the operation window. When it is necessary to adjust the shape of the baffle 300, the cover is removed and the positions of the first end 310 and the second end 320 are adjusted.

[0042] In some embodiments, the baffle member 300 includes a fixing member, and at least one side of the fixing member is provided with a plurality of sub-baffles. The plurality of sub-baffles are slidably connected to each other, and the sub-baffles near the fixing member are slidably connected to the fixing member. When the baffle member 300 needs to be in an unfolded state, the sub-baffles slide to the corresponding positions respectively.

[0043] For example, a first sub-baffle is connected to one side of the fixing member, a second sub-baffle is slidably connected to the first sub-baffle, and a third sub-baffle is slidably connected to the second sub-baffle. When the baffle member 300 is in the retracted state, the first sub-baffle, the second sub-baffle, and the third sub-baffle overlap each other. When the baffle member 300 is in the unfolded state, one end of the first sub-baffle slides to the edge of the fixing member, one end of the second sub-baffle slides to the edge of the first sub-baffle away from the fixing member, and one end of the third sub-baffle slides to the edge of the second sub-baffle away from the fixing member, thereby forming an unfolded shielding cross-flow fan.

[0044] In some embodiments, the baffle member 300 includes a plurality of sub-baffles that are folded and connected to each other. When the baffle member 300 is in a retracted state, the plurality of sub-baffles are folded to each other. When the baffle member 300 is in an unfolded state, the plurality of sub-baffles unfold sequentially.

[0045] In some embodiments, the indoor unit further includes a filter 500 disposed on the side of the heat exchanger 200 away from the cross-flow fan 100 and surrounding the heat exchanger 200.

[0046] Understandably, with the baffle 300 configured as described above, the filter can be rinsed directly without disassembling the filter screen 500.

[0047] In some embodiments, the indoor unit further includes a spray mechanism 600, which is disposed on the side of the heat exchanger 200 away from the cross-flow fan 100, and is used to spray cleaning water onto the heat exchanger 200.

[0048] In some embodiments, the indoor unit further includes a spray mechanism 600, which is disposed on the side of the filter 500 away from the heat exchanger 200. The spray mechanism 600 is used to spray cleaning water onto the filter 500 and the heat exchanger 200.

[0049] It is understandable that by installing a spray mechanism 600 on the indoor unit, the filter screen 500 and heat exchanger 200 can be automatically cleaned by spraying cleaning water when the baffle 300 is in the unfolded state.

[0050] In some embodiments, the spray mechanism 600 includes a water tank 610, a water pump 640, and at least one spray bar 620. The water pump 640 is connected to the water tank 610, one end of the spray bar 620 is connected to the water pump 640, the spray bar 620 is arranged along the length of the indoor unit, and the spray bar 620 has a plurality of spray nozzles.

[0051] It is understandable that the cleaning water is pre-stored in the water tank 610 and then pumped to the spray bar 620 by the water pump 640. The filter screen 500 and the heat exchanger 200 are cleaned through the spray nozzles of the spray bar 620.

[0052] For example, the spray bar 620 is a pipe structure, and the spray nozzles provided on the spray bar 620 spray the cleaning water in the pipe structure onto the filter screen 500 and the heat exchanger 200.

[0053] For example, the water pump 640 is a booster pump, which pressurizes the cleaning water and sprays it out from the spray pipe to improve the cleaning effect of the spray mechanism 600.

[0054] In some implementations, when multiple spray bars 620 are connected to a water pump 640, the multiple spray bars 620 and the water pump 640 are connected in parallel.

[0055] In some embodiments, the spraying mechanism 600 further includes a drive motor 630, which is connected to the end of the spraying rod 620 away from the water pump 640, and the drive motor 630 is used to drive the spraying rod 620 to rotate.

[0056] It should be noted that one end of the spray bar 620 is connected to the water pump 640 via a movable joint, and the other end is connected to the drive motor 630. The drive motor 630 drives it to rotate, thereby achieving cleaning of multiple locations on the indoor unit.

[0057] In some embodiments, the present invention also provides an air conditioner that includes the above-described indoor unit. Since the air conditioner has the above-described indoor unit, that is, includes some or all of the embodiments of the above-described indoor unit, the corresponding air conditioner has the beneficial effects of some or all of the embodiments of the above-described indoor unit.

[0058] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made based on the contents of the present utility model specification and drawings under the application concept of the present utility model, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
