Detailed Implementation

[0063] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of structures consistent with some aspects of this disclosure as detailed in the appended claims.

[0064] The technical solutions provided by the various embodiments of this disclosure are described in detail below with reference to the accompanying drawings.

[0065] In existing technology, to prevent people from touching the high-speed rotating cross-flow fan wheel by inserting their hands into the air outlet of the indoor unit, thus causing unnecessary injury, finger guards are installed on the indoor unit of the air conditioner to isolate the cross-flow fan wheel. Currently, the finger guards of air conditioner indoor units are generally made of stainless steel wire. When the heating or cooling mode is turned on, abnormal noise will occur due to factors such as thermal expansion and contraction of the material, and the noise level is relatively high, which will affect the user experience to some extent. At the same time, the finger guards of air conditioner indoor units on the market are all internal structures. During maintenance and cleaning, the air outlet duct of the air conditioner indoor unit must be removed before the finger guard can be removed, which is a cumbersome maintenance or cleaning process, resulting in low after-sales maintenance or cleaning efficiency.

[0066] Based on this, the present disclosure provides an indoor unit for an air conditioner. Figure 1 This is a schematic diagram of the structure of an indoor unit of an air conditioner according to an exemplary embodiment. Figure 1 ,like Figure 1 As shown, the indoor unit 1 of the air conditioner may include:

[0067] Air outlet duct 11, with air outlet 111;

[0068] The protective component 12 is located inside the air outlet duct 11 and is disposed at the air outlet 111 to protect the air outlet 111 so that objects outside the indoor unit 1 of the air conditioner cannot extend into the air outlet duct 11 through the air outlet 111.

[0069] The protective component 12 is provided with a mounting buckle 121, and the air outlet duct 11 is provided with a mounting groove 112 on the duct wall; the mounting buckle 121 is inserted into the mounting groove 112, so that the protective component 12 can be detachably installed in the air outlet duct 11.

[0070] In this embodiment of the disclosure, the indoor unit of the air conditioner can be a vertical air conditioner, and correspondingly, the air outlet duct can be vertically arranged. The air outlet duct can be a channel through which airflow flows from the high-speed rotating cross-flow fan of the indoor unit to the air outlet. The protective component can be a finger guard or other protective mesh; the object outside the indoor unit of the air conditioner can be a user's finger or other items, such as a ruler, a pen, etc.

[0071] Understandably, the aforementioned protective components can be vertically installed within the air outlet duct, and the dimensions of the protective components match the duct wall of the air outlet duct. The aforementioned mounting clips can be located at the upper and lower ends of the protective components, and the aforementioned mounting slots can also be located on the upper and lower duct walls of the air outlet duct, allowing the mounting clips to be inserted into the mounting slots.

[0072] Here, the aforementioned protective component can be detachably installed in the air outlet duct by engaging the aforementioned mounting clip with the aforementioned mounting slot. For example, when installing the protective component, the mounting clip can be inserted into the mounting slot from left to right, and correspondingly, when disassembling the protective component, the mounting clip can be slid out of the mounting slot from right to left; or, when installing the protective component, the mounting clip can also be inserted into the mounting slot from right to left, and correspondingly, when disassembling the protective component, the mounting clip can be slid out of the mounting slot from left to right. This disclosure does not impose any limitations on the embodiments.

[0073] It should be noted that the number of the aforementioned mounting clips and mounting slots can be set according to the actual application, and this embodiment does not limit the number. For example, the number of mounting clips and mounting slots can be two or more, as long as the number of mounting clips and mounting slots is the same.

[0074] In one embodiment, the protective component 12 is made of plastic. This allows the protective component to be made of more flexible material by replacing metal with plastic, resulting in less noise generated when airflow passes through it and improving the user experience.

[0075] This disclosure provides an indoor unit for an air conditioner, comprising: an air outlet duct with an air outlet; and a protective component located within the air outlet duct and disposed at the air outlet. The protective component has a mounting clip, and the duct wall of the air outlet duct has a mounting groove. The mounting clip is inserted into the mounting groove, allowing the protective component to be detachably installed within the air outlet duct. Thus, by placing the protective component at the air outlet of the air outlet duct, the air outlet is protected, preventing objects outside the indoor unit from entering the air outlet duct through the air outlet. Unlike existing technologies where protective components are internally mounted, this method uses a mounting clip on the protective component that engages with the mounting groove on the duct wall of the air outlet duct, allowing the protective component to be detachably installed within the air outlet duct. This facilitates the installation and removal of the protective component, making it convenient for users to clean and improving after-sales maintenance efficiency.

[0076] In one implementation, such as Figure 1 and 2 As shown, the indoor unit 1 of the air conditioner may further include:

[0077] The air guide assembly 17 is located at the air outlet 111 and is used to guide the airflow flowing out of the air outlet 111;

[0078] The protective component 12 is located on the side of the air guide component 17 that is away from the air outlet 111.

[0079] Here, the air guide component can be a sweeping blade; the sweeping blade can guide the airflow to either left or right or up and down, which can be determined according to the setting of the sweeping blade and the user's settings in actual application. This disclosed embodiment does not impose any restrictions.

[0080] In this way, by installing an air guide component at the air outlet of the air duct, the airflow at the air outlet can be guided, so that the airflow at the air outlet blows out in the direction set by the user, thereby improving the user experience.

[0081] Figure 3 This is a schematic diagram illustrating the structure of a protective component in an indoor unit of an air conditioner according to an exemplary embodiment, such as... Figure 3 As shown, the protective component 12 in this embodiment may include:

[0082] Protective netting 122;

[0083] The mounting buckles 121 are located at opposite ends of the protective netting 122.

[0084] The protective netting can be equipped with mounting clips at both ends, allowing it to be detachably installed in the air outlet duct by engaging with the mounting groove.

[0085] In this embodiment of the disclosure, the indoor unit of the air conditioner can be a vertical air conditioner, and correspondingly, the protective net can be set vertically, and the mounting buckle can be located at the upper and lower ends of the protective net.

[0086] In one implementation, such as Figure 4 As shown, a schematic diagram of a protective mesh in an indoor unit of an air conditioner is illustrated. The protective mesh 122 in this embodiment may include:

[0087] Multiple vertical ribs 1221, and multiple horizontal ribs 1222 connecting two adjacent vertical ribs 1221;

[0088] Among them, the two adjacent horizontal bars 1222 that connect the different vertical bars 1221 are arranged alternately.

[0089] In this way, by setting staggered horizontal and vertical ribs in the protective net, the overall strength of the protective net can be made more uniform.

[0090] The vertical ribs can be set in a direction parallel to the air outlet direction of the air outlet duct, thereby reducing the resistance of the protective net to the airflow flowing out of the air outlet duct.

[0091] Here, multiple vertical ribs can be of the same length, and multiple horizontal ribs can also be of the same length; that is, the spacing between two adjacent vertical ribs can be the same. Similarly, the spacing between two adjacent horizontal ribs located between the same two vertical ribs can also be the same.

[0092] In one embodiment of this disclosure, such as Figure 5 As shown, the cross-sectional area of ​​the vertical rib 1221 first increases and then decreases along the air outlet direction A of the air outlet duct 11; wherein, the cross-section of the vertical rib 1221 is parallel to the air outlet direction A.

[0093] It is understandable that the shape of the cross section of the aforementioned vertical rib parallel to the air outlet direction can be spindle-shaped, with the middle part of the spindle being wider than the two ends. The smaller end of the spindle can face the inner side of the aforementioned air outlet duct, i.e., away from the air outlet; the larger end can face the outer side of the aforementioned air outlet duct, i.e., close to the air outlet.

[0094] In this way, by setting the smaller end of the vertical rib facing into the air outlet duct, the resistance of the protective net to the airflow flowing out of the air outlet duct can be reduced.

[0095] In one embodiment, see Figure 6 , Figure 7 as well as Figure 9 The diagram shows a structural schematic of a positioning groove and positioning rib in an indoor unit of an air conditioner. The protective component 12 in this embodiment may further include:

[0096] The positioning groove 123 is located in the middle of the protective net 122;

[0097] The air outlet duct 11 is also provided with positioning ribs 113 that are spaced apart from the mounting groove 112 on the duct wall;

[0098] The positioning rib 113 is located within the positioning groove 123.

[0099] Here, the upper and lower ends of the aforementioned protective net are provided with mounting buckles, and the aforementioned positioning groove can be located in the middle of the mounting buckles at the upper and lower ends; correspondingly, the upper and lower duct walls of the aforementioned air outlet duct are provided with mounting grooves, and the aforementioned positioning rib can be located in the middle of the mounting grooves on the upper and lower duct walls.

[0100] In other words, the above-mentioned mounting clips and mounting slots are positioned in a corresponding manner, and the above-mentioned positioning slots and positioning ribs are also positioned in a corresponding manner, thereby better enabling the protective components to be detachably installed in the air outlet duct.

[0101] In this way, the protective components can be further fixed inside the air outlet duct by engaging the positioning groove located in the middle of the protective net with the positioning rib on the duct wall.

[0102] In one embodiment, see Figure 2 , Figure 7 and Figure 8The bottom of the positioning groove 123 has a through hole 1231; the indoor unit 1 of the air conditioner may further include:

[0103] Fastener 13 passes through the through hole 1231 and is fixed to the positioning rib 113.

[0104] The fasteners mentioned above can be a type of mechanical part used to fasten two or more parts or components together into a whole, such as screws, bolts, and nuts.

[0105] It should be noted that the number of through holes and fasteners can be set according to actual application conditions, and this embodiment does not limit the number. For example, the number of through holes and fasteners can both be one or multiple, as long as the number of through holes and fasteners is the same.

[0106] In this way, the positioning ribs and positioning grooves can be further fixed with fasteners, reducing the abnormal noise generated when the airflow from the air outlet duct passes through the protective components during the operation of the indoor unit of the air conditioner.

[0107] In one implementation, such as Figure 7 As shown, the bottom of the positioning groove 123 is also provided with a clearance groove 1232 that is spaced apart from the through hole 1231;

[0108] The clearance groove 1232 is connected to the positioning groove 123 and is used to accommodate the protruding part 1131 of the positioning rib 113 in the air outlet direction A of the air outlet duct 11.

[0109] The distance between the protrusion 1131 and the air outlet 111 is less than the distance between the bottom of the positioning groove 123 and the air outlet 111.

[0110] Here, the protruding part of the aforementioned positioning rib can be clamped, which can be used to hold the air guide component in the indoor unit of the air conditioner. Understandably, the aforementioned clearance groove is provided at the bottom of the aforementioned positioning groove, and the aforementioned clearance groove is connected to the positioning groove, so that the aforementioned protruding part can pass through the clearance groove through the positioning groove and engage with the air guide component.

[0111] In this embodiment of the disclosure, the opening of the positioning groove can be away from the air outlet of the air outlet duct, the protruding part of the positioning rib can face the air outlet of the air outlet duct, and the clearance groove can be a slot that passes through both ends so that the protruding part passes through the positioning groove.

[0112] It should be noted that the number of the aforementioned relief grooves and protrusions can be set according to the actual application, and this embodiment does not limit the number. For example, the number of relief grooves and protrusions can both be one or multiple, as long as the number of relief grooves and protrusions is the same.

[0113] In this way, by setting a clearance groove at the bottom of the positioning groove that is connected to the positioning groove, the protruding part of the positioning rib can pass through the clearance groove and engage with the air guide assembly, thereby improving the stability between the components in the indoor unit of the air conditioner.

[0114] Figure 10 This is a schematic diagram illustrating the structure of a mounting groove and a guide groove in an indoor unit of an air conditioner according to an exemplary embodiment, such as... Figure 10 As shown in the embodiments of this disclosure, the indoor unit of the air conditioner 1 may further include:

[0115] The first baffle 14 is disposed on the wall of the air outlet duct 11;

[0116] A horizontal plate 15 is disposed on the duct wall of the air outlet duct 11 and is parallel to the first baffle 14.

[0117] The first baffle 14, the horizontal plate 15, and the air duct wall of the air outlet duct 11 constitute the mounting groove 112.

[0118] Here, both the first stop and the horizontal plate can be cuboids. The width of the first stop can be greater than the width of the horizontal plate, so as to better insert the mounting clip into the mounting slot.

[0119] In this embodiment of the present disclosure, the first stop block and the horizontal plate can both be disposed on the upper and lower air duct walls of the air outlet duct; the two ends of the horizontal plate can be connected to the side air duct walls of the air outlet duct.

[0120] It should be noted that the number of the first baffles can be set according to the actual application, and this embodiment does not limit the number. For example, if there is one first baffle, then one mounting groove is provided on the duct wall of the air outlet duct; if there are two first baffles, then two mounting grooves are provided on the duct wall of the air outlet duct, and so on.

[0121] The embodiments of this disclosure provide an indoor unit of an air conditioner, which can form an installation groove by setting a first block and a horizontal plate on the duct wall of the air outlet duct, so as to cooperate with the installation buckle of the protective component, so that the protective component can be detachably installed in the air outlet duct, thereby facilitating the installation and removal of the protective component, making it convenient for users to disassemble and clean, and improving after-sales maintenance efficiency.

[0122] In one embodiment, see Figure 10 and Figure 11 The indoor unit 1 of the air conditioner may further include:

[0123] Two second blocks 16 are disposed on both sides of the first block 14, and together with the horizontal plate 15 and the air duct wall of the air outlet duct 11, they form a guide groove 114.

[0124] The protective component 12 may further include guide blocks 124 disposed on both sides of the mounting buckle 121. The guide blocks 124 cooperate with the guide groove 114 to guide the mounting buckle 121 into the mounting groove 112.

[0125] In this way, by setting second blocks on both sides of the first block, forming guide grooves with the horizontal plate and the air duct wall of the air outlet, the guide blocks of the protective component on both sides of the mounting buckle are used to guide the mounting buckle to be inserted into the mounting groove.

[0126] The second stop block can also be a cuboid, and its width can be the same as the width of the first stop block. The number of guide blocks and guide grooves can be the same.

[0127] Here, the length of the first stop block in the air outlet direction perpendicular to the air outlet duct can be less than the length of the second stop block in the air outlet direction perpendicular to the air outlet direction, thereby reducing the stroke of the mounting clip when inserted into the mounting slot.

[0128] In this embodiment of the disclosure, the guide groove and the mounting groove can be on the same straight line, and the guide block and the mounting buckle can also be on the same straight line; the distance between the guide block and the mounting buckle can be the same as the distance between the second stop and the first stop, so that the mounting buckle and the mounting groove can cooperate with each other, and the guide block and the guide groove can cooperate with each other.

[0129] In one embodiment, see Figure 10 and Figure 11 The mounting buckle 121 may include: a connecting root 1211 and a buckle end 1212; the connecting root 1211 is connected to the protective net 122; the buckle end 1212 is suspended and is engaged in the mounting groove 112.

[0130] In this way, the buckle end, which is suspended, can be engaged with the mounting slot, making the mounting buckle flexible and allowing the protective component to be easily detached and installed in the air outlet duct.

[0131] The buckle end does not contact the protective net, but can be indirectly connected to the protective net through the connecting root, so that the buckle is flexible.

[0132] In this embodiment of the present disclosure, a groove facing the air outlet is formed between the aforementioned buckle end and the aforementioned connection root. The groove can be used to accommodate the aforementioned first stop block, thereby allowing the buckle end to engage in the mounting groove.

[0133] In one embodiment of this disclosure, see Figure 10 and Figure 11 The buckle end 1212 has a first guide slope 12121; the first guide slope 12121 is inclined toward the air outlet 111;

[0134] The first baffle 14 has a second guide slope 141 on its end face facing the air outlet direction A perpendicular to the air outlet duct 11. The second guide slope 141 is inclined in a direction away from the air outlet 111.

[0135] The first guide slope 12121 is parallel to the second guide slope 141.

[0136] Here, the cooperation between the first guide slope and the second guide slope can be used to guide the insertion of the mounting clip into the mounting slot, so that the mounting clip can be better engaged with the mounting slot.

[0137] It should be noted that the installation direction of the protective components in the indoor unit of the air conditioner can be determined based on the orientation of the first guide slope and the second guide slope. For example, as Figure 10 and Figure 11 As shown, if the first guide slope faces left and the second guide slope faces right, the protective assembly can be installed on the air outlet duct from right to left; or, if the first guide slope faces right and the second guide slope faces left, the protective assembly can be installed on the air outlet duct from left to right.

[0138] In this way, the protective component can be guided in the air outlet duct by the cooperation between the first guide slope set at the end of the buckle and the second guide slope set at the first stop, which facilitates the installation and removal of the protective component, makes it convenient for users to disassemble and clean, and improves the efficiency of after-sales maintenance.

[0139] In one embodiment of this disclosure, see Figure 10 and Figure 11 The guide block 124 has a third guide slope 1241; the third guide slope 1241 is inclined toward the air outlet 111;

[0140] The second baffle 16 has a fourth guide slope 161 on its end face facing the air outlet direction A perpendicular to the air outlet duct 11. The fourth guide slope 161 is inclined in a direction away from the air outlet 111.

[0141] The third guide slope 1241 is parallel to the fourth guide slope 161.

[0142] Here, the cooperation between the third and fourth guide slopes can be used to guide the guide block into the guide groove, making it easier for the guide block to engage better with the guide groove.

[0143] In this embodiment of the disclosure, the orientation of the third guide slope can be the same as that of the first guide slope, and the orientation of the fourth guide slope can be the same as that of the second guide slope.

[0144] It should be noted that the installation direction of the protective components in the indoor unit of the air conditioner can also be determined based on the orientation of the third guide ramp and the fourth guide ramp. For example, as Figure 10 and Figure 11 As shown, if the third guide slope faces left and the fourth guide slope faces right, the protective component can be installed on the air outlet duct from right to left; or, if the third guide slope faces right and the fourth guide slope faces left, the protective component can be installed on the air outlet duct from left to right.

[0145] In this way, the protective component can be guided in the air outlet duct by the cooperation between the third guide slope set in the guide block and the fourth guide slope set in the second stop block, which facilitates the installation and removal of the protective component, makes it convenient for users to disassemble and clean, and improves the efficiency of after-sales maintenance.
