[0042] Figure 1 is a schematic diagram of an indoor unit 20 of an air conditioner according to an embodiment of the present invention; Figure 2 is a schematic diagram of the air guide cylinder of the indoor unit 20 of the air conditioner according to an embodiment of the present invention.

[0043] The present invention provides an indoor unit 20 of an air conditioner having an air guide cylinder 32. The indoor unit 20 of the air conditioner includes a housing 22 and a plurality of air guide cylinders 32. An air inlet and an air outlet are formed in the housing 22, and a air supply duct communicating the air inlet and the air outlet is defined inside the housing 22. The plurality of air guide cylinders 32 are arranged at intervals in the air supply duct along the length direction of the air outlet; the air guide cylinder 32 is rotatably arranged in the air supply duct and defines an air guide cavity penetrating through the air guide cylinder 32.

[0044] Refer to Figure 1 and Figure 2 As shown, in the air supply duct of the indoor unit 20 of the present embodiment near the air outlet, a plurality of air guide cylinders 32 are arranged at intervals along the length direction of the air outlet. Each air guide cylinder 32 defines an air guide cavity 32A penetrating through itself as shown in Figure 2 As shown, so that part of the air flow in the air supply duct can pass through the air guide cylinder 32 from the air guide cavity 32A. Both the inner and outer side walls of the air guide cylinder 32 can guide the air flow, and the guiding effect on the air flow passing through the air guide cylinder 32 from the air guide cavity 32A is more obvious. According to the rotation direction of the air guide cylinder 32, the air guide cylinder 32 can direct the outgoing air flow to the front or the front obliquely. Under the reciprocating rotation of the air guide cylinder 32, the indoor unit 20 of the air conditioner can swing the air supply left and right accordingly.

[0045] In the indoor unit 20 of the present embodiment, the air guide cylinder 32 is provided to replace the existing air guide plate for air guiding. The outgoing air flow can flow along the outer side wall of the air guide cylinder 32 or pass through the air guide cavity 32A and flow along the inner side wall of the air guide cylinder 32. Therefore, both the inner and outer sides of the air guide cylinder 32 can play a role in air guiding and provide an air guiding effect similar to or even better than that of the existing air guide plate.

[0046] Refer to Figure 2 As shown, in some alternative embodiments, the air guide cavity 32A is in the shape of a cylindrical tube.

[0047] The air guide cavity 32A defined by the inner side wall of the air guide cylinder 32 in this embodiment is in the shape of a cylindrical tube extending in the front-rear direction, and the air flow enters from the rear end of the air guide cylinder 32 and blows out from the front end. The opening areas of the front and rear ends are basically the same, and the flow velocity of the air flow will not be significantly changed.

[0048] In some optional embodiments, an inner wall of the air guide tube 32 is formed with air guide ribs 322 that extend in a spiral shape along the front-to-back direction.

[0049] refer to Figure 2 As shown, the air guide ribs 322 are spirally extended on the inner wall of the air guide tube 32, and the air guide ribs 322 in the air guide tube 32 can be one continuous rib or two or more ribs spaced apart. The air guide ribs 322 formed on the inner wall of the air guide tube 32 in this embodiment can make the part of the air supply airflow flowing along the inner wall of the air guide tube 32 have a certain spirality while flowing forward under the influence of the air guide ribs 322. Therefore, the air flow is more likely to be dispersed to the surroundings, which not only makes the air flow effect softer, reduces the discomfort caused by the user being blown directly by the air flow, but also makes it easier to mix with the surrounding ambient air, thereby changing the ambient temperature more evenly.

[0050] After long-term use, even if a dust filter is provided on the air inlet side of the air conditioner indoor unit 20, a large amount of dust cannot be prevented from being adsorbed on the blades of the fan and in the air supply duct. If the dust is not cleaned in time, it is easy to breed bacteria, causing the user to pollute the ambient air when using the air conditioner indoor unit 20. However, since an air guide plate is usually provided in the air supply duct, it is difficult for the cleaning tool to move in the air supply duct under the obstruction of the air guide plate, making it difficult for the user to effectively clean the fan located deep in the air supply duct without disassembling the air conditioner indoor unit 20.

[0051] In some optional embodiments, the air conditioner indoor unit 20 further includes: a plurality of support members 33. The support members 33 are arranged in the air supply duct; each air guide tube 32 is detachably arranged on a support member 33; and the support member 33 is used to drive the air guide tube 32 to rotate.

[0052] refer to Figure 2 As shown, the air conditioner indoor unit 20 of this embodiment is also provided with support members 33 corresponding to the air guide tubes 32 in the air supply duct. Each air guide tube 32 is detachably arranged on a support member 33 to facilitate the user to disassemble the air guide tube 32, thereby leaving sufficient cleaning space in the air supply duct and also facilitating the user to clean the air guide tube 32.

[0053] The air guide tube 32 of this embodiment is fixed on the support member 33 and rotates under the drive of the support member 33, and the pivot shaft 34 of the transmission mechanism for connecting the air conditioner indoor unit 20 is connected to the support member 33. The transmission mechanism is used to drive each air guide tube 32 to rotate synchronously, so it is simultaneously connected to the pivot shaft 34 on each support member 33.

[0054] Further, in some alternative embodiments, the support member 33 has a bottom wall corresponding to the shape of the air guide cylinder 32, and a support wall extending from the edge of the bottom wall to the outer side wall of the air guide cylinder 32 and detachably connected to the air guide cylinder 32; the bottom wall of the support member 33 is spaced from the outer side wall of the air guide cylinder 32, thereby defining a dust collection chamber 32B. A plurality of dust leakage holes 32C communicating the upper and lower air guide chambers 32A and the dust collection chamber 32B are formed in the air guide cylinder 32.

[0055] Reference Figure 2 As shown, a groove is formed on the outer side wall of the air guide cylinder 32 of this embodiment, and the shape of the support wall of the support member 33 corresponds to the shape of the groove, so that the air guide cylinder 32 can be detachably clamped to the support member 33. The bottom wall of the support member 33 is spaced from the outer side wall of the air guide cylinder 32 vertically, and cooperates with the surrounding support walls to define a closed dust collection chamber 32B, and the air flow cannot flow through the dust collection chamber 32B.

[0056] The support member 33 of this embodiment is located below the air guide cylinder 32, and the dust leakage holes 32C are all formed in the bottom part of the inner side wall height of the air guide cylinder 32. A plurality of dust leakage holes 32C communicating the upper and lower air guide chambers 32A and the dust collection chamber 32B are formed in the air guide cylinder 32, so that the dust that might originally fall into the air guide cylinder 32 can pass through the dust leakage holes 32C and fall into the dust collection chamber 32B. Since the air guide cylinder 32 is detachably connected to the support member 33, the user can conveniently clean the exposed dust collection chamber 32B after disassembling the air guide cylinder 32.

[0057] Figure 3 is a schematic diagram of the air guide cylinder 32 of the indoor unit 20 of the air conditioner according to another embodiment of the present invention.

[0058] As an alternative embodiment of the above embodiment, in some alternative embodiments, the bottom of the air guide cylinder 32 further defines a dust collection chamber 32B spaced from the air guide chamber 32A. A plurality of dust leakage holes 32C communicating the upper and lower air guide chambers 32A and the dust collection chamber 32B are formed in the air guide cylinder 32. And the air guide cylinder 32 is detachably arranged in the air supply duct.

[0059] Reference Figure 3 As shown, the air guide cylinder 32 of this embodiment is an integrally formed part, and simultaneously defines the air guide chamber 32A and the dust collection chamber 32B. The air guide chamber 32A and the dust collection chamber 32B are vertically spaced and the dust collection chamber 32B is located below the air guide chamber 32A. The dust leakage holes 32C are all formed in the bottom part of the inner side wall height of the air guide cylinder 32. A plurality of dust leakage holes 32C communicating the upper and lower air guide chambers 32A and the dust collection chamber 32B are formed in the air guide cylinder 32, so that the dust that might originally fall into the air guide cylinder 32 can pass through the dust leakage holes 32C and fall into the dust collection chamber 32B.

[0060] The pivot shaft 34 for connecting the air guide tube 32 and the transmission mechanism in this embodiment can be integrally formed on the air guide tube 32 and detachably inserted into the transmission mechanism, so that the air guide tube 32 is detachably arranged in the air supply duct. Of course, the pivot shaft 34 can also be integrally formed on the transmission mechanism and detachably inserted into the air guide tube 32.

[0061] To facilitate the user to clean the dust collection cavity 32B, the air guide tube 32 in this embodiment can have an opening at the front end of the dust collection cavity 32B, and a baffle 35 is detachably arranged at the opening. When the baffle 35 is installed on the air guide tube 32, the dust collection cavity 32B is in a closed state where it is only connected to the air guide cavity 32A through the dust leakage holes 32C, and the air flow cannot pass through the dust collection cavity 32B. When the baffle 35 is removed from the air guide tube 32, the dust collection cavity 32B is in an exposed state, facilitating the user to clean.

[0062] Figure 4 is Figure 1 A cross-sectional schematic diagram of the indoor unit 20 of the air conditioner shown.

[0063] Reference Figure 1 and Figure 4 As shown, in some alternative embodiments, both the air inlet and the air outlet are opened on the front side surface of the housing 22.

[0064] In this embodiment of the indoor unit 20 of the air conditioner, both the air inlet and the air outlet are opened on the front side surface of the housing 22, so that air enters and exits from the front side of the indoor unit 20 of the air conditioner at the same time. Therefore, the indoor unit 20 of the air conditioner in this embodiment can be suitable for an embedded installation environment in a cabinet. The embedded indoor unit 20 of the air conditioner can hide the body in the cabinet, making the home layout more beautiful and meeting the user's need for integrated home decoration.

[0065] In addition, the indoor unit 20 of the air conditioner in this embodiment can be not only an embedded indoor unit 20 of the air conditioner embedded in a cabinet, but also a wall-mounted indoor unit 20 of the air conditioner hung on a wall, or a floor-standing indoor unit 20 of the air conditioner standing vertically on the ground. The shapes and positions of the air inlet and the air outlet of the indoor unit 20 of the air conditioner are adapted to the shape of the housing 22 of the indoor unit 20 of the air conditioner.

[0066] In some alternative embodiments, the indoor unit 20 of the air conditioner further includes an air outlet baffle 36. The air outlet baffle 36 is arranged at the air outlet for opening and closing the air outlet. And the rotation axis of the air outlet baffle 36 is located on the side close to the air inlet.

[0067] Figure 1 To show the air guide tube 32 arranged in the air supply duct, the air outlet baffle 36 is particularly hidden. Reference Figure 4As shown, the air outlet baffle 36 of this embodiment is rotatably arranged at the air outlet for opening and closing the air outlet. Since the air inlet and the air outlet of the indoor unit 20 of the air conditioner in this embodiment are located on the same side, in order to reduce the air flow discharged from the air outlet being directly sucked back into the indoor unit 20 of the air conditioner from the air inlet again, the rotation axis of the air outlet baffle 36 in this embodiment is arranged on the side close to the air inlet, so that when the air outlet baffle 36 rotates and opens the air outlet, the air inlet and the air outlet can be separated, and the air flow discharged towards the direction close to the air inlet can be reduced.

[0068] In addition, in addition to being used for opening and closing the air outlet, the air outlet baffle 36 can also play a certain role in guiding the air flow.

[0069] In some alternative embodiments, the indoor unit 20 of the air conditioner further includes an air inlet grille. The air inlet grille is arranged at the air inlet; the air inlet grille includes a plurality of grille plates 38 that are parallel to each other and parallel to the length direction of the air outlet, and each grille plate 38 has an inclined surface facing forward and downward.

[0070] In order to further reduce the air flow discharged from the air outlet being directly sucked back into the indoor unit 20 of the air conditioner from the air inlet again, this embodiment also improves the air inlet grille arranged at the air inlet. Refer to Figure 4 As shown, the air inlet grille is composed of a plurality of grille plates 38 that are parallel to each other and spaced apart, and air can enter the indoor unit 20 of the air conditioner from the air inlet through the gaps between adjacent grille plates 38. In particular, each grille plate 38 Figure 4 As shown, has an inclined surface facing forward and downward, so that the air flow formed at the air inlet tends to flow obliquely from the outside to the inside towards the direction close to the air inlet, thereby reducing the air sucked by the air inlet from the side close to the air outlet.

[0071] Refer to Figure 4 As shown, in addition to the housing 22 and the air guide cylinder 32, the indoor unit 20 of the air conditioner in this embodiment further includes a cross-flow fan 24, an evaporator 28, and a first air duct wall 26 and a second air duct wall 27 that define the air supply duct, which are arranged in the housing 22. The first air duct wall 26 is located on the side of the air supply duct close to the air inlet, and a volute tongue is formed at one end close to the cross-flow fan 24. The air guide cylinder 32 is arranged between the first air duct wall 26 and the second air duct wall 27, and a transmission mechanism (not shown in the figure) for driving each air guide cylinder 32 to rotate is arranged on the other side of the second air duct wall 27, and the pivot shaft 34 passes through the second air duct wall 27 to connect the air guide cylinder 32 with the transmission mechanism. The evaporator 28 is arranged between the air inlet and the cross-flow fan 24.

[0072] When the air conditioner indoor unit 20 operates, the cross-flow fan 24 rotates to promote the formation of an air flow that enters from the air inlet, flows through the evaporator 28, and the cross-flow fan 24, and flows along the air supply duct. The transmission mechanism drives the air guide cylinder 32 to rotate, thereby guiding the outlet air flow to change the flow direction.

[0073] Figure 5 It is a schematic diagram of the air conditioner 10 according to an embodiment of the present invention.

[0074] The air conditioner 10 of this embodiment includes an air conditioner indoor unit 20, and also includes an air conditioner outdoor unit and a refrigerant pipeline connecting the two. The compressor, condenser, and throttling device in the air conditioner outdoor unit are connected to the evaporator 28 in the air conditioner indoor unit 20 by the refrigerant pipeline, and together with other necessary components, they jointly constitute the refrigeration cycle system of the air conditioner 10. On the side of the air conditioner indoor unit 20, it can both refrigerate and blow cold air flow, and can also have a heating function and blow hot air flow.

[0075] The air conditioner indoor unit 20 of this embodiment, as the indoor part of the air conditioner, in addition to having refrigeration and heating functions, can also additionally have functions such as dehumidifying, humidifying, air purifying, and introducing fresh air to the indoor environment.

[0076] The air conditioner indoor unit 20 of this embodiment sets both the air inlet and the air outlet on the front surface of the housing, so that the air conditioner indoor unit 20 takes in air and discharges air from the front side at the same time. Therefore, it is particularly suitable for being embedded in a cabinet for use, that is, being used as an embedded air conditioner indoor unit 20.

[0077] In the embodiment where the air conditioner 10 is an embedded air conditioner 10, the cabinet for placing the air conditioner indoor unit 20 can be various cabinets and can be used for storing items. The present invention does not limit the specific use of the cabinet. For example, the cabinet can be for household use and can be specifically applied to the kitchen, bathroom, living room, or bedroom. For example, the cabinet can be set in the kitchen to accommodate the air conditioner indoor unit 20.

[0078] However, the air conditioner 10 of this embodiment is not limited to the embedded air conditioner 10. The air conditioner indoor unit 20 can be either the indoor part of an embedded air conditioner 10 installed in various cabinets or the indoor terminal unit of a central air conditioner, or the indoor part of a wall-mounted air conditioner 10 or other air conditioner indoor units 20, which is not limited here.

[0079] 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, still, without departing from the spirit and scope of the present invention, many other variations or modifications that conform to the principles of the present invention can be directly determined or derived based on the content disclosed in the present invention.
