Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an indoor unit of an air conditioner. Background Art

[0002] With the development of science and technology, people's living standards are constantly improving. As an electrical device for keeping cool in summer and warm in winter, air conditioners are becoming more and more indispensable in people's lives, work and entertainment. In order to meet the needs of users, the functions of air conditioners are also constantly being innovated, such as the fresh air function.

[0003] At present, in the prior art, some user scenarios require fresh air, for example, there are many guests at home and the indoor fresh air flow is thin. Then the air conditioner manufacturer increases the shell and adds a fresh air module inside the shell to achieve the fresh air function. Such an air conditioner will occupy more indoor space of the user, reducing the daily usable space of the user. In addition, for example, when there is no guest at the user's home, the number of people is small, the indoor fresh air flow is sufficient, and there is no need to turn on the fresh air function. At this time, the user does not need the fresh air module, but the fresh air module cannot be removed from the inside of the air conditioner, and the air conditioner will still occupy the user's indoor space. Therefore, air conditioner manufacturers upgrade the air conditioner with a built-in fresh air module to add it outside the shell. However, in order to ensure the connection stability of the fresh air module and the shell, the connection between the fresh air module and the shell is complicated, and the disassembly and assembly process is very cumbersome. Even the fresh air module cannot be removed at all, which cannot meet the user's need to remove the fresh air module when the fresh air function is not needed, greatly reducing the user's experience.

[0017] Furthermore, the fixed clamp head and the fixed clamp body are both plate-shaped structures; and,

[0018] The connection corner between the fixed clamp head and the fixed clamp body is in the form of an arc surface, so as to allow the edge of the fixed clamp hole to slide between the fixed clamp head and the fixed clamp body.

[0020] Further, the fresh air device is detachably connected to the housing in the left-right direction; and,

[0021] The disassembly and assembly structure is located above the locking structure.

[0022] Furthermore, the fresh air device comprises:

In addition, when the fresh air device is assembled on the air conditioner body, after the fixed hook of the clamping structure passes through the fixed clamping hole of the clamping structure, there is a disassembly gap between the fixed clamping head of the fixed hook and the shell around the fixed clamping hole. The disassembly gap is used to allow the fresh air device to deviate from the shell around the clamping structure when the disassembly structure causes the fresh air device and the shell to be partially disassembled, so as to facilitate the user to disassemble and assemble the fresh air device on the air conditioner body. Specifically, when the user needs to disassemble the fresh air device, after the disassembly structure is disassembled, the disassembly gap can be converted into a deviation gap between the fresh air device and the air conditioner body, and the fresh air device and the air conditioner body are no longer in close contact, and then the fresh air device can be rotated around the clamping structure as a whole, so that there is a certain disassembly angle between the fresh air device and the air conditioner body, and then the fixed hook and the fixed clamping hole can be separated very smoothly. At the same time, when the user needs to install the fresh air device on the air conditioner body, first insert the fixed hook into the fixed hole of the fresh air device at a certain disassembly angle, and then push the fresh air device around the clamping structure to approach the air conditioner body, so that the disassembly hook and the disassembly hole are clamped in place. Therefore, the air conditioner indoor unit of the utility model can make the process of disassembling and installing the fresh air module very simple and smooth for the user, and is convenient for the user to operate. It can well meet the user's needs to remove the fresh air module when the fresh air function is not needed, and to install the fresh air module when the fresh air function is needed, which greatly guarantees the user's use experience.

[0056] Combine the following Figures 1 to 7 The air conditioner indoor unit of this embodiment will be described in detail. Figure 1 It is a structural schematic diagram of an indoor unit of an air conditioner according to an embodiment of the utility model; Figure 2 yes Figure 1 An enlarged schematic diagram of the area "A" in the figure; Figure 3 It is an exploded schematic diagram of an air conditioner body and a cabinet in an air conditioner indoor unit according to an embodiment of the utility model; Figure 4 It is a structural schematic diagram of a fresh air device in an indoor unit of an air conditioner according to an embodiment of the utility model; Figure 5 It is one of the cross-sectional schematic diagrams of an indoor unit of an air conditioner according to an embodiment of the utility model; Figure 6 This is a second cross-sectional schematic diagram of an indoor unit of an air conditioner according to an embodiment of the utility model; Figure 7 is a cross-sectional schematic diagram of an air conditioner body according to an embodiment of the utility model, wherein Figure 7 The solid arrows in show the flow path of the air flow in the housing.

[0057] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6In this embodiment, the indoor unit of the air conditioner includes an air conditioner body 100, a fresh air device 200, a disassembly and assembly structure 300 and a locking structure 400.

[0058] The air conditioner body 100 is used to provide heat exchange airflow to the indoor space, and the air conditioner body 100 includes a shell 110 .

[0059] The fresh air device 200 is used to provide fresh air flow to the indoor space.

[0060] The disassembly structure 300 and the locking structure 400 are used to jointly detachably connect one end of the fresh air device 200 to one end outside the shell 110 .

[0061] The engaging structure 400 includes a fixing hole 410 and a fixing hook 420. The fixing hole 410 is provided on the end of the housing 110 relative to the fresh air device 200; the fixing hook 420 is provided on the end of the fresh air device 200 relative to the housing 110, and the fixing hook 420 extends toward the housing 110 and is inserted into the fixing hole 410.

[0062] The fixed hook 420 includes a fixed clamp head 421 and a fixed clamp body 422 connected between the fixed clamp head 421 and the fresh air device 200. There is a disassembly gap 500 between the fixed clamp head 421 and the inner wall of the shell 110. The disassembly gap 500 is used to allow the fresh air device 200 to deviate from the shell 110 around the locking structure 400 when the disassembly structure 300 prompts the fresh air device 200 and the shell 110 to be partially disassembled.

[0063] In the indoor unit of the air conditioner of the utility model, the fresh air device 200 can be assembled on the air conditioner body 100 through the disassembly structure 300 and the snap-fit ​​structure 400 according to the needs of the user, and can also be disassembled from the air conditioner body 100 through the disassembly structure 300 and the snap-fit ​​structure 400 according to the needs of the user. In addition, when the fresh air device 200 is assembled on the air-conditioning body 100, after the fixed hook 420 of the locking structure 400 passes through the fixed hole 410 of the locking structure 400, a disassembly gap 500 is provided between the fixed head 421 of the fixed hook 420 and the shell 110 around the fixed hole 410. The disassembly gap 500 is used to allow the fresh air device 200 to deviate in a direction away from the shell 110 around the locking structure 400 (the contact point between the inner wall of the fixed hole 410 and the fixed hook 420) when the disassembly structure 300 prompts the partial disassembly of the fresh air device 200 and the shell 110, so as to facilitate the user's disassembly and assembly operations of the fresh air device 200 on the air-conditioning body 100.

[0064] Specifically, when the user needs to disassemble the fresh air device 200, after the disassembly structure 300 is disassembled, the disassembly gap 500 can be converted into a deviation gap between the fresh air device 200 and the air conditioner body 100, and the fresh air device 200 and the air conditioner body 100 are no longer in close contact, and the fresh air device 200 can be rotated around the snap-fit ​​structure 400 as a whole, so that there is a certain disassembly angle between the fresh air device 200 and the air conditioner body 100, and the fixed hook 420 and the fixed hole 410 can be separated smoothly. At the same time, when the user needs to install the fresh air device 200 on the air conditioner body 100, the fresh air device 200 is first inserted into the fixed hole 410 at a certain disassembly angle, and then the fresh air device 200 is pushed around the snap-fit ​​structure 400 close to the air conditioner body 100, so that the disassembly hook 320 and the disassembly hole 310 are snapped into place.

[0065] It should also be understood that if there is no disassembly gap, the fixing clamp head 421 of the fixing clamp hook 420 will fit tightly against the inner wall of the housing 110. The fresh air device 200 will also fit tightly against the air conditioner body 100, and the fresh air device 200 cannot deviate from the air conditioner body 100. If the fresh air device 200 is to be disassembled, the fixing clamp body 422 needs to be deformed so that the fixing clamp head 421 can be separated from the fixing clamp hole 410.

[0066] Therefore, the air conditioner indoor unit of the utility model can make the process of removing and installing the fresh air module for users very simple and smooth, which is convenient for users to operate. It can well meet the needs of users to remove the fresh air module when the fresh air function is not needed, and to install the fresh air module again when the fresh air function is needed, thereby greatly ensuring the user's usage experience.

[0067] Reference Figure 4 , Figure 5 and Figure 6 In this embodiment, the connection corner between the fixed clamp head 421 and the fixed clamp body 422 is an arc surface to allow the edge / inner wall of the fixed clamp hole 410 to slide between the fixed clamp head 421 and the fixed clamp body 422.

[0068] It can be understood that setting the connecting corner between the fixed clamp head 421 and the fixed clamp body 422 as an arc surface can ensure that during the process of disassembling and installing the fresh air module, the edge of the fixed clamp hole 410 moves smoothly between the fixed clamp head 421 and the fixed clamp body 422.

[0069] During the installation of the fresh air module, the fixed clamp head 421 can be placed on the fixed clamp hole 410, and the fresh air device 200 can be smoothly rotated toward the air-conditioning body 100. At the same time, the edge / inner wall of the fixed clamp hole 410 can smoothly slide over the connecting corner between the fixed clamp head 421 and the fixed clamp body 422, so that the fixed clamp body 422 contacts the inner wall of the fixed clamp hole 410, and the fresh air device 200 is installed in place; during the removal of the fresh air module, the sliding process of the fixed clamp body 422 and the fixed clamp hole 410 is opposite, but whether it is the process of removing or installing the fresh air device 200, it will be completed smoothly to ensure stability when removing and installing the fresh air device 200, thereby ensuring the user experience.

[0070] In some other embodiments, the fixing clamp head 421 and the fixing clamp body 422 are connected at a right angle. However, such a structure will bring great obstacles and setbacks to the process of disassembling and installing the fresh air module.

[0071] Specifically, during the process of disassembling and installing the fresh air device 200, after the inner wall of the fixed card hole 410 slides to the right-angle corner between the fixed card head 421 and the fixed card body 422, it is necessary to increase the force or change the direction of the applied force to slide the inner wall of the fixed card hole 410 out of the right-angle corner between the fixed card head 421 and the fixed card body 422, which may increase the difficulty of the disassembly and assembly process of the fresh air device 200.

[0072] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the disassembly structure 300 includes a disassembly hole 310 and a disassembly hook 320 .

[0073] The disassembly and assembly hole 310 is formed on the end of the housing 110 opposite to the fresh air device 200 .

[0074] The disassembly hook 320 is arranged on the end of the fresh air device 200 relative to the shell 110, and the disassembly hook 320 extends toward the shell 110 and is clamped in the clamping hole. The disassembly hook 320 includes a disassembly clamp head 321 and a disassembly clamp body 322 connected between the disassembly clamp head 321 and the fresh air device 200, one end of the disassembly clamp head 321 is connected to the disassembly clamp body 322, and the other end of the disassembly clamp head 321 extends in a direction away from the clamping structure 400 and the disassembly clamp body 322, one end of the fixed clamp head 421 is connected to the fixed clamp body 422, and the other end of the fixed clamp head 421 extends in a direction away from the fixed clamp body 422 and the disassembly structure 300.

[0075] It is understandable that, through the matching connection between the disassembly hook 320 and the disassembly hole 310, and the matching connection between the fixed hook 420 and the fixed hole 410, the fresh air device 200 can be stably connected to the air conditioner body 100. Therefore, the disassembly structure 300 and the engaging structure 400 can effectively ensure the connection stability between the fresh air device 200 and the air conditioner body 100 while promoting the detachable connection of the fresh air device 200 to the air conditioner body 100.

[0076] Furthermore, one end of the disassembly card head 321 is connected to the disassembly card body 322, and the other end of the disassembly card head 321 extends in a direction away from the engaging structure 400 and the disassembly card body 322 (when the fresh air device 200 is detachably connected to the air conditioner body 100 in the left-right direction, the other end of the disassembly card head 321 extends upward; when the fresh air device 200 is detachably connected to the top of the air conditioner body 100, the other end of the disassembly card head 321 can extend to the right; when the fresh air device 200 is detachably connected to the bottom of the air conditioner body 100, the other end of the disassembly card head 321 can extend to the left). In this way, the contact area between the disassembly card head 321 and the housing 110 around the disassembly card hole 310 can be increased, and the connection stability between the fresh air device 200 and the air conditioner body 100 can be further ensured.

[0077] Furthermore, one end of the fixed clamp 421 is connected to the fixed clamp body 422, and the other end of the fixed clamp 421 extends in a direction away from the fixed clamp body 422 and the disassembly structure 300 (when the fresh air device 200 is detachably connected to the air conditioner body 100 in the left-right direction, the other end of the fixed clamp 421 extends downward; when the fresh air device 200 is detachably connected to the top of the air conditioner body 100, the other end of the fixed clamp 421 can extend to the left; when the fresh air device 200 is detachably connected to the bottom of the air conditioner body 100, the other end of the fixed clamp 421 can extend to the right). In this way, the fixed clamp 421 can well avoid the risk of the fixed hook 420 coming out of the fixed clamp hole 410, and further ensure the stability of the fresh air device 200 being detachably connected to the air conditioner body 100.

[0078] At the same time, during the process of disassembling and installing the fresh air device 200, the fixed hook 420 can have an effective length to abut against the inner wall of the fixed hole 410, thereby preventing the fresh air device 200 from falling out of the fixed hole 410 when the fresh air device 200 is not rotated to the disassembly angle.

[0079] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the fixed clamp head 421 and the fixed clamp body 422 are both plate-shaped structures.

[0080] Both the fixing chuck 421 and the fixing body 422 are set as plate-like structures. That is, the fixing chuck 421 and the fixing body 422 can extend in the front-rear direction. Further, it can be further avoided that during the disassembly and assembly of the fresh air device 200, the fresh air device 200 falls out of the fixing card hole 410 when the fresh air device 200 is not rotated to the disassembly and assembly angle. And it can ensure the contact area between the inner wall of the fixing card hole 410 and the fixing hook 420, and ensure that the disassembly and assembly of the fresh air device 200 can be completed stably.

[0081] Moreover, the corresponding fixing card hole 410 extends in the front-rear direction.

[0082] Refer to Figure 3 、 Figure 4 In this embodiment, the disassembly and assembly hook 320 extends in the front-rear direction. Correspondingly, the disassembly and assembly card hole 310 also extends in the front-rear direction. To further increase the contact area between the disassembly and assembly chuck 321 and the housing 110 around the disassembly and assembly card hole 310, and further ensure the connection stability between the fresh air device 200 and the air conditioner body 100.

[0083] At the same time, it should also be understood that when both the fixing hook 420 and the disassembly and assembly hook 320 extend in the front-rear direction, the contact area or the area to be contacted between them and the housing 110 around the corresponding card hole is ensured. Furthermore, compared with the clamping structure of multiple buckles and card holes in the prior art, the disassembly and assembly structure 300 and the clamping structure 400 in this embodiment do not require cumbersome and multiple buckling or unbuckling. It ensures the simplicity of the disassembly and assembly of the fresh air device 200 and the connection stability between the fresh air device 200 and the air conditioner body 100.

[0084] Refer to Figure 5 In this embodiment, the distance L between the fixing chuck 421 and the fresh air device 200 is greater than the distance M between the disassembly and assembly chuck 321 and the fresh air device 200, so as to promote the formation of the disassembly gap 500 when the disassembly and assembly structure 300 and the clamping structure 400 jointly and detachably connect the fresh air device 200 to the outside of the housing 110. Furthermore, the simplicity and operability of the fresh air device 200 during the disassembly and assembly process are realized.

[0085] In some alternative embodiments, the feature that the distance between the fixing chuck 421 and the fresh air device 200 is greater than the distance between the disassembly and assembly chuck 321 and the fresh air device 200 can be replaced by the feature that the length of the fixing body 422 is greater than the length of the disassembly and assembly body 322. Similarly, the formation of the disassembly gap 500 can be realized after the fresh air device 200 is installed in place.

[0086] In this embodiment, the elastic coefficient of the fixing body 422 is greater than the elastic coefficient of the disassembly and assembly body 322.

[0087] It should be understood that, in the process of disassembling the fresh air device 200, the disassembly card body 322 needs to be deformed so that the disassembly card hook 320 can be separated from the disassembly card hole 310; or, in the process of installing the fresh air device 200, the disassembly card body 322 needs to be deformed so that the disassembly card hook 320 can be installed in the disassembly card hole 310. Therefore, the disassembly card body 322 needs a certain elasticity. That is, in this embodiment, the disassembly card body 322 can be set as an elastic member.

[0088] Furthermore, during the process of disassembling and assembling the fresh air device 200 , the entire weight of the fresh air device 200 must be supported on the fixed card body 422 , and thus the fixed card body 422 needs to have good rigidity to ensure the stability of the disassembly and assembly process.

[0089] Furthermore, by making the elastic coefficient of the fixed card body 422 greater than the elastic coefficient of the disassembly card body 322, it can be ensured that the disassembly and assembly processes of the fresh air device 200 can be completed stably.

[0090] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the fresh air device 200 is detachably connected to the housing 110 in the left-right direction; and the disassembly structure 300 is located above the locking structure 400.

[0091] It can be known that by positioning the disassembly and assembly structure 300 above the locking structure 400, during the process of disassembling and assembling the fresh air device 200, the overall weight of the fresh air device 200 will be applied to the fixed locking body 422, ensuring that the process of disassembling and assembling the fresh air device 200 can be carried out effortlessly, safely and stably.

[0092] If the disassembly and assembly structure 300 is disposed below the engaging structure 400 , during the process of disassembling and assembling the fresh air device 200 , the user or other personnel still needs to lift the fresh air device 200 to complete the disassembly and assembly process.

[0093] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the fresh air device 200 includes a fresh air housing 210 and a decorative ridge 211 .

[0094] An installation gap 600 is provided between the fresh air housing 210 and the casing 110 .

[0095] The decorative ridge 211 is arranged between the fresh air casing 210 and the shell 110, the decorative ridge 211 is located in front of the installation gap 600, and the decorative ridge 211 extends between the fresh air casing 210 and the shell 110 and in front of the installation gap 600. The decorative ridge 211 is used to block the installation gap 600 and to maintain the clamping force between the disassembly hook 320 and the disassembly hole 310.

[0096] A disassembly opening 610 connected to the installation gap 600 is formed at the top of the shell 110, the top of the fresh air outer shell 210, and between the fresh air outer shell 210, the shell 110 and the decorative ridge 211. The disassembly opening 610 is used to expose the disassembly card body 322 to the outside of the air conditioner indoor unit.

[0097] It is understandable that, by providing the decorative convex strip 211, an installation gap 600 can be formed between the fresh air housing 210 and the housing 110, and a disassembly opening 610 communicating with the installation gap 600 is formed at the top of the housing 110 and the top of the fresh air housing 210. Furthermore, when disassembling the fresh air device 200, an object can be used to touch the disassembly card body 322 through the disassembly opening 610, so that the disassembly card body 322 is deformed, and then the disassembly hook 320 can be disengaged from the disassembly card hole 310. This further facilitates the user (and / or maintenance personnel) to disassemble the fresh air device 200 from the air conditioner body 100.

[0098] In addition, the provision of the decorative ridge 211 can well maintain the engagement force between the disassembly hook 320 and the disassembly hole 310 , thereby ensuring the connection stability between the fresh air device 200 and the air conditioner body 100 .

[0099] Furthermore, the decorative convex strip 211 covers the installation gap 600, which can well ensure the consistency of the front side of the air conditioner indoor unit, ensure the aesthetics of the air conditioner indoor unit, and enhance the user experience.

[0100] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 In this embodiment, the decorative ridge 211 extends between the fresh air housing 210 and the shell 110 and in front of the installation gap 600, that is, when the fresh air device 200 is detachably connected to the air-conditioning body 100 / shell 110 in the left-right direction, the decorative ridge 211 extends in the up-down direction.

[0101] In some other embodiments, when the fresh air device 200 is detachably connected to the air conditioner body 100 / the casing 110 in the up-down direction, the decorative ridge 211 extends in the left-right direction.

[0102] In some other embodiments, when the fresh air device 200 is detachably installed at the bottom end of the air conditioner body 100, the disassembly and assembly opening 610 can be formed at the right end of the fresh air housing 210 facing right; when the fresh air device 200 is detachably installed at the top end of the air conditioner body 100, the disassembly and assembly opening 610 can be formed at the left end of the fresh air housing 210 facing left. Similarly, the above technical effects of facilitating the user (and / or maintenance personnel) to remove the fresh air device 200 from the air conditioner body 100, ensuring the connection stability between the fresh air device 200 and the air conditioner body 100, and improving the user experience can be achieved.

[0103] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 In this embodiment, the decorative rib 211 and the fresh air housing 210 are of an integral structure, which ensures the consistency between the decorative rib 211 and the fresh air housing 210, further ensures the consistency of the front side of the indoor unit of the air conditioner, guarantees the aesthetics of the indoor unit of the air conditioner, and improves the user experience.

[0104] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 In this embodiment, the fresh air device 200 further includes a support rib 212.

[0105] The support rib 212 is arranged between the fresh air housing 210 and the housing 110. The support rib 212 is located behind the installation gap 600, and the support rib 212 extends between the fresh air housing 210 and the housing 110 and behind the installation gap 600. The support rib 212 is used to maintain the clamping force between the disassembly and assembly hook 320 and the disassembly and assembly hole 310.

[0106] It can be understood that the arrangement of the support rib 212 can well maintain the clamping force between the disassembly and assembly hook 320 and the disassembly and assembly hole 310, and ensure the connection stability between the fresh air device 200 and the air conditioner body 100.

[0107] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 In this embodiment, the support rib 212 extends between the fresh air housing 210 and the housing 110 and behind the installation gap 600, that is, when the fresh air device 200 is detachably connected to the air conditioner body 100 / housing 110 in the left-right direction, the support rib 212 extends in the up-down direction.

[0108] In some other embodiments, when the fresh air device 200 is detachably connected to the air conditioner body 100 / the casing 110 in the up-down direction, the supporting ridges 212 extend in the left-right direction.

[0109] In particular, when the fresh air device 200 is set at the top of the air conditioner body 100 / shell 110, the decorative ridges 211 and the supporting ridges 212 can bear the gravity of the fresh air device 200, and can well ensure the flatness of the fresh air device 200 on the shell 110.

[0110] Furthermore, the disassembly opening 610 is located between the fresh air housing 210 , the shell 110 , the decorative ridge 211 and the supporting ridge 212 .

[0111] Reference Figure 1 and Figure 4 In the present embodiment, a fresh air outlet 213 extending in the up-down direction is provided on the front end of the fresh air housing 210 .

[0112] It is understandable that in order to ensure that the air conditioner indoor unit can have a shorter length and at the same time ensure that the fresh air device 200 has a larger air outlet, the fresh air outlet 213 can extend in the up and down direction at the front end of the fresh air housing 210.

[0113] In some other embodiments, when the fresh air device 200 is installed to the top or bottom of the air conditioner body 100 in the up and down direction, the fresh air outlet 213 can be changed to extend in the left and right direction on the front end of the fresh air housing 210.

[0114] Reference Figure 5 and Figure 6 In this embodiment, a fresh air inlet 214 is disposed at the rear end of the fresh air housing 210; and a fresh air duct 215 for connecting the fresh air inlet 214 and the fresh air outlet 213 is provided in the fresh air housing 210. The fresh air device 200 further includes a fresh air fan 220. The fresh air fan 220 is disposed in the fresh air duct 215. The fresh air device 200 can then cause the fresh air flow at the fresh air inlet 214 to flow into the indoor space through the fresh air duct 215 and the fresh air outlet 213.

[0115] Moreover, the fresh air inlet 214 can well ensure the aesthetics of the front side of the air conditioner indoor unit.

[0116] In addition, the fresh air inlet 214 is connected to a fresh air duct 216 extending to the outdoor space, so that outdoor fresh air is delivered to the fresh air inlet 214 .

[0117] Reference Figure 5 and Figure 6In this embodiment, the fresh air fan 220 is a centrifugal fan of a centrifugal fan, which can effectively ensure the fresh air intake of the fresh air device 200, ensure the indoor fresh air content, and improve the user experience. At the same time, the fresh air duct 215 includes an air inlet chamber 2151 and an air outlet chamber 2152 connected to each other. The fresh air fan 220 is arranged in the air outlet chamber 2152, the fresh air outlet 213 is connected to the air outlet chamber 2152, and the fresh air inlet 214 is connected to the air inlet chamber 2151. And the connecting port 2153 between the air inlet chamber 2151 and the air outlet chamber 2152 is located in the axial direction of the fresh air fan 220.

[0118] Reference Figure 3 In this embodiment, a heat exchange air inlet 111 is opened at the upper front end of the shell 110, and a heat exchange air outlet 112 is opened at the lower front end of the shell 110; and the fresh air device 200 is detachably connected to the bottom or top end of the shell 110 through a disassembly structure 300 and a snap-fit ​​structure 400.

[0119] It can be understood that since the heat exchange inlet 111 and the heat exchange outlet 112 are both arranged at the front end of the shell 110, the fresh air device 200 can be installed at the top or bottom of the shell 110 without affecting the normal cooling, heating and other functions of the air conditioner indoor unit.

[0120] Reference Figure 3 In this embodiment, the air conditioner indoor unit is used to be embedded in the cabinet 700; and the air conditioner body 100 and the fresh air device 200 are used to be embedded in the cabinet 700 together; or, the air conditioner body 100 is used to be independently embedded in the cabinet 700.

[0121] It is understandable that the indoor unit of the air conditioner of this embodiment can adopt an embedded solution to ensure the aesthetics of the indoor space. When the user chooses the installation solution that the air conditioner body 100 is independently embedded in the cabinet 700, the volume of the cabinet 700 can be reduced, making the installation solution of the indoor unit of the air conditioner in the indoor space more delicate and compact, greatly ensuring the aesthetics of the indoor unit of the air conditioner. Of course, the user can also choose a cabinet 700 with a slightly larger volume, embed the indoor unit of the air conditioner in the cabinet 700, and install the fresh air device 200 on the air conditioner body 100 when the fresh air function is needed, and remove the fresh air device 200 when the fresh air function is not needed. The solution of the detachable fresh air device 200 implemented in this embodiment can meet the various needs of users.

[0122] Furthermore, since the heat exchange air inlet 111 and the heat exchange air outlet 112 of the air conditioner indoor unit of this embodiment are both located at the front end of the housing 110, when the air conditioner indoor unit is embedded in the cabinet 700, the air inlet and outlet of the air conditioner indoor unit will not be affected, thereby ensuring the performance of the air conditioner indoor unit.

[0123] Reference Figure 7 In the present embodiment, the air conditioner body 100 further includes a volute 120 , a heat exchange fan 130 , and a heat exchange component 140 disposed in the shell 110 .

[0124] The heat exchange fan 130 is arranged in the volute cavity of the volute 120, and the heat exchange component 140 is arranged on the volute 120, and is arranged in an inverted V shape above the heat exchange fan 130. Specifically, the heat exchange component 140 includes a first indoor heat exchanger 141, a second indoor heat exchanger 142 and a third indoor heat exchanger 143, and the second indoor heat exchanger 142 is connected between the first indoor heat exchanger 141 and the third indoor heat exchanger 143. And the first indoor heat exchanger 141, the second indoor heat exchanger 142 and the third indoor heat exchanger 143 are arranged from front to back. The first indoor heat exchanger 141 is arranged in front of the heat exchange fan 130, the second indoor heat exchanger 142 is arranged in the front upper part of the heat exchange fan 130, and the third indoor heat exchanger 143 is arranged in the rear upper part of the heat exchange fan 130.

[0125] In addition, a first air inlet duct 114 and a second air inlet duct 113 are provided in the housing 110. The first air inlet duct 114 and the second air inlet duct 113 are separated by a partition 150. The front end of the first air inlet duct 114 and the front end of the second air inlet duct 113 are connected to the heat exchange port, the first air inlet duct 114 is located in front of the first indoor heat exchanger 141 and the second indoor heat exchanger 142, and the first indoor heat exchanger 141 and the second indoor heat exchanger 142 are located at the tail end of the first air inlet duct 114; the tail end of the second air inlet duct 113 extends to the third indoor heat exchanger 143, and the tail end of the second air inlet duct 113 can extend to the rear of the third indoor heat exchanger 143.

[0126] It is understandable that, since the heat exchange air inlet 111 is located in front of the housing 110, the airflow entering the housing 110 through the heat exchange air inlet 111 may not flow backward through the third indoor heat exchanger 143, but only through the first indoor heat exchanger 141 and the second indoor heat exchanger 142. In this way, the heat exchange amount of the heat exchange airflow is insufficient, and the cooling / heating effect is deteriorated. At the same time, the heat exchange amount of the third indoor heat exchanger 143 is insufficient, and ice will appear when the indoor unit of the air conditioner is in the cooling mode, or overheating will occur when the indoor unit of the air conditioner is in the cooling mode. Furthermore, a first air inlet duct 114 and a second air inlet duct 113 are formed by the partition 150. The second air inlet duct 113 can fully guide the airflow at the heat exchange inlet 111 to the third indoor heat exchanger 143, thereby effectively ensuring the heat exchange capacity of the third indoor heat exchanger 143, ensuring the cooling / heating effect of the air conditioner indoor unit, avoiding freezing or overheating of the third indoor heat exchanger 143, and ensuring the stable operation of the air conditioner indoor unit.

[0127] Reference Figure 7 In this embodiment, the second air inlet duct 113 is located above the first air inlet duct 114 to ensure the stability of the air flow in the first air inlet duct 114 and the second air inlet duct 113 .

[0128] Reference Figure 2 In this embodiment, the air conditioner body 100 further includes an air induction plate 160, one end of which is rotatably connected between the heat exchange air inlet 111 and the heat exchange air outlet 112 of the housing 110. When the air conditioner body 100 is turned on and operates in cooling / heating mode, the other end of the air induction plate 160 is arranged to face forward and upward, and the air induction plate 160 is in an air induction state at this time. Then, the air intake airflow will enter the housing 110 from the heat exchange air inlet 111 from top to bottom, and the heat exchange airflow will flow out from the heat exchange air outlet 112. In this way, the air induction plate 160 separates the air intake airflow from the heat exchange airflow, effectively avoiding the mutual disturbance between the air intake airflow and the heat exchange airflow, which affects the working performance of the indoor unit of the air conditioner. And the air induction plate 160 has a closed state of closing the heat exchange air inlet 111.

[0129] In addition, in the present embodiment, the air conditioner body 100 further includes a driving connecting rod 170, and the driving connecting rod 170 is used to drive the air induction plate 160 to move and switch between the air induction state and the closed state.

[0130] Reference Figure 2 In this embodiment, the housing 110 includes a frame 115 and a front cover 116, and the front cover 116 is arranged on the frame 115. The disassembly and assembly holes 310 and the fixing holes 410 can be opened on the frame 115. The volute 120, the heat exchange fan 130, the heat exchange component 140, etc. are all arranged in the frame 115, and the air guide plate 160, the driving connecting rod 170, the heat exchange air inlet 111, and the heat exchange air outlet 112 are all arranged on the front cover 116. In this way, the housing 110 is divided into the frame 115 and the front cover 116, and even when the indoor unit of the air conditioner is embedded in the cabinet 700, the installation process, repair operation, and maintenance operation are very convenient.

[0131] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention.
