[0057] This invention proposes an indoor unit for an air conditioner.

[0058] Please see Figures 1 to 6 This invention proposes an indoor air conditioning unit 100, including a body 110, a door 120, and a drive assembly 160. The body 110 has an air outlet 115 and a clearance opening 114; the door 120 is movable relative to the body 110 to open or close the air outlet 115; the drive assembly 160 is disposed within the body 110, and includes a drive mechanism 170 and a connector 180 connected to the drive mechanism 170 (e.g., ...). Figure 14 and Figure 15 As shown, the drive mechanism 170 is located above or below the clearance opening 114, and the end of the connector 180 away from the drive mechanism 170 passes through the clearance opening 114 and is connected to the switch door 120.

[0059] Specifically, the indoor unit 100 is a floor-standing air conditioner. The body 110 of the indoor unit 100 extends vertically and can be cylindrical, square, or other shapes. The body 110 includes a casing 111, which comprises a shell body 112 and a panel 113. The shell body 112 has an air inlet, an air outlet 115, and a heat exchange duct connecting the air inlet and outlet 115. The panel 113 is located on the front side of the shell body 112. The body 110 also includes a heat exchange module located within the heat exchange duct, used to exchange heat with the airflow passing through the duct, thereby achieving cooling or heating. The heat exchange module may only have cooling functionality or may have both cooling and heating functions simultaneously. Without loss of generality, the heat exchange module includes a heat exchanger and a heat exchange fan. The heat exchange fan drives airflow from the air inlet into the heat exchange duct, and after heat exchange by the heat exchanger, it is blown out from the air outlet 115, thereby achieving indoor cooling or heating. Other specific structures of the indoor unit 100 can be referred to existing technologies and will not be elaborated here.

[0060] In this embodiment of the invention, the switch door 120 extends along the height direction of the body 110, and the height of the switch door 120 can be approximately equal to the height of the body 110. The switch door 120 is movable relative to the housing 111 to open or close the air outlet 115. To improve the texture of the switch door 120 and thus the overall texture of the indoor air conditioning unit 100, the switch door 120 can be made of a metal material, such as, but not limited to, aluminum alloy. Furthermore, to drive the switch door 120 to move, a drive assembly 160 can be used to drive the switch door to move. Considering that the switch door 120 is a single-piece structure and is relatively tall, the number of drive assemblies 160 can be at least two to better drive the switch door 120 to move. Optionally, to simplify the structure of the indoor unit 100 while ensuring smooth movement of the door 120, in one embodiment, there are two drive components 160. One drive component 160 is located at the upper end of the body 110, and the other drive component 160 is located in the middle of the body 110. It should be noted that the drive component 160 being located in the middle of the body 110 can be understood as being located above the accommodating cavity 116. This way, the drive component 160 will not occupy the internal space of the accommodating cavity 116, thus not affecting the storage of the unit, and also will not increase the size of the body 110 by installing the drive component 160 outside the accommodating cavity 116. Of course, the number of drive components 160 can also be one; there is no specific limitation.

[0061] The structure of the drive assembly 160 can also be varied. For example, the drive assembly 160 includes a drive motor 171, a gear 172, and a rack, with the drive motor 171 driving the switch door 120 to move through the meshing of the gear 172 and rack; or, the drive assembly 160 includes a drive motor 171 and a rocker arm structure, with the drive motor 171 driving the switch door 120 to move through the rocker arm structure; of course, the drive assembly 160 may also include a rotary cylinder, which drives the switch door 120 to move. Here, no specific limitation is made on the structure and driving method of the drive assembly 160. Specifically, the drive assembly 160 includes a drive mechanism 170, which is located inside the body 110. Considering that the switch door 120 is located outside the body 110, in order to better drive the switch door 120 to move, the drive assembly 160 also includes a connector 180. The drive mechanism 170 is driven to connect to the switch door 120 through the connector 180 to drive the switch door 120 to move.

[0062] The housing 111 is provided with a clearance opening 114 (e.g. Figure 4 and Figure 5 As shown, the end of the connector 180 away from the drive mechanism 170 passes through the clearance opening 114 and connects to the switch door 120. That is, the end of the connector 180 away from the drive mechanism 170 extends out of the housing 111 and connects to the switch door 120. Since the switch door 120 can move circumferentially relative to the housing 111, the clearance opening 114 extends circumferentially along the housing 111, allowing the connector 180 to move within the clearance opening 114. Furthermore, considering that when the switch door 120 is open, the clearance opening 114 is relatively long, it easily exposes the drive mechanism 170 inside the housing 111, causing the user to see the cluttered structure inside the housing 111 and affecting the user's visual experience. Therefore, to prevent the drive mechanism 170 inside the housing 111 from being exposed through the clearance opening 114 when the door 120 is opened, thus causing the user to see the messy structure inside the housing 111, the drive mechanism 170 can be positioned above or below the clearance opening 114. This way, even when the door 120 is opened, the user cannot see the drive mechanism 170 inside the housing 111 through the clearance opening 114. Based on this, to ensure that the drive mechanism 170 is located above or below the clearance opening 114, the connector 180 can be bent. The structure of the connector 180 will be described in detail below.

[0063] The indoor unit 100 of the air conditioner of the present invention includes a body 110, a door 120, and a drive assembly 160. The body 110 is provided with an air outlet 115 and a clearance opening 114. The door 120 is located outside the body 110 and is movable relative to the body 110 to open or close the air outlet 115. The drive assembly 160 is located inside the body 110 and includes a drive mechanism 170 and a connector 180 connected to the drive mechanism 170. The drive mechanism 170 is located in the clearance opening 114. Above or below the drive mechanism 170, the end of the connector 180 away from the clearance opening 114 is connected to the switch door 120. In this way, on the one hand, the drive mechanism 170 drives the switch door 120 to move through the connector 180 to open or close the air outlet 115. On the other hand, the drive mechanism 170 and the clearance opening 114 are located at different heights on the body 110, which can prevent the user from seeing the drive mechanism 170 inside the air conditioner indoor unit 100 when the switch door 120 is opened, improve the user's viewing experience, and also prevent external dust, flying insects, etc. from entering the drive mechanism 170 and affecting the normal use of the drive mechanism 170.

[0064] Please refer to the following: Figures 11 to 15 In one embodiment, the connector 180 includes a first connecting portion 181 and a second connecting portion 182 connected to the first connecting portion 181. The first connecting portion 181 is located above or below the second connecting portion 182. The first connecting portion 181 is connected to the drive mechanism 170, and the second connecting portion 182 passes through the clearance opening 114 and is connected to the switch door 120.

[0065] Specifically, when the first connecting part 181 is above the second connecting part 182, the driving mechanism 170 can be positioned above the clearance opening 114; when the first connecting part 181 is below the second connecting part 182, the driving mechanism 170 can be positioned below the clearance opening 114. There are many ways to connect the first connecting part 181 to the driving mechanism 170, such as screw connection, snap-fit ​​connection, or plug-in connection. Similarly, there are also various ways to connect the second connecting part 182 to the door 120, such as screw connection, snap-fit ​​connection, or plug-in connection, and no specific limitation is made.

[0066] Further, please refer to Figure 12 The connector 180 further includes a third connecting portion 183, which extends in the vertical direction and connects the first connecting portion 181 and the second connecting portion 182.

[0067] It is understandable that, in order to improve the overall structural strength of the connector 180, the connector 180 can be integrally formed, that is, the first connecting part 181, the second connecting part 182, and the third connecting part 183 are a single-piece structure. Here, the third connecting part 183 mainly serves to connect the first connecting part 181 and the second connecting part 182, while also positioning the first connecting part 181 above or below the second connecting part 182. The third connecting part 183 can be a straight structure or a bent structure, which can be selected and designed according to actual needs. At the same time, the height of the third connecting part 183 can also be adjusted according to actual needs, so that the position of the clearance opening 114 is not limited by the installation position of the drive mechanism 170, and thus the position of the clearance opening 114 can be adjusted according to the internal space of the body 110.

[0068] Please see Figures 7 to 11 In one embodiment, a fixing member 130 is provided on the inner side of the switch door 120, and the fixing member 130 is connected to the second connecting part 182.

[0069] The fixing member 130 can be detachably mounted on the switch door 120 or protrude from the switch door 120. This improves the overall structural strength of the switch door 120 and ensures the reliability of the connection between the switch door 120 and the connecting member 180. The fixing member 130 is detachably connected to the second connecting part 182, which facilitates the installation and removal of the switch door 120 and the drive assembly 160. There are many ways to connect the fixing member 130 and the second connecting part 182, such as a snap-fit ​​connection and / or a screw connection.

[0070] In one embodiment, to further improve the reliability and firmness of the connection between the fixing member 130 and the second connecting part 182, multiple fixing parts can be provided on the switch door 120, that is, the connecting member 180 includes a first fixing part 140 and a second fixing part 150 (e.g., Figure 11 As shown in the diagram, the first fixing part 140 and the second fixing part 150 are spaced apart along the width direction of the opening / closing door 120. The first fixing part 140 is engaged with the second connecting part 182. Optionally, the first fixing part 140 is provided with an engaging structure 143, and the second connecting part 182 is provided with a slot 184 (as shown in the diagram). Figure 11 Figure 12 and Figure 13 As shown, the engaging structure 143 engages with the slot 184.

[0071] Specifically, the first fixing part 140 is generally T-shaped. Please refer to [link / reference]. Figure 8 The first fixing part 140 includes a locking plate 141 and a connecting arm 142. The locking plate 141 is opposite to and spaced apart from the switch door 120, and the connecting arm 142 connects the locking plate 141 and the switch door 120. Optionally, the locking plate 141 has a symmetrical structure with respect to the connecting arm 142. By configuring the first fixing part 140 into two parts, the locking plate 141 and the connecting arm 142, the connection stability and reliability between the first fixing part 140 and the connector 180 can be effectively improved. The second fixing part 150 can be a connecting block, a connecting strip, or a connecting rib, etc. By simultaneously connecting the first fixing part 140 and the second fixing part 150 of the fixing member 130 to the connector 180, the connection stability and reliability between the connector 180 and the second fixing part can be improved.

[0072] Please see Figure 9 and Figure 10 In this embodiment, to facilitate the insertion of the engaging structure 143 into the slot 184 and its engagement with the slot 184, the engaging structure 143 may include an insertion section 144 for easy insertion into the slot 184, and an engaging section 145 connected to the insertion section 144. The insertion section 144 and the engaging section 145 are arranged along the height direction of the switch door 120. The width α3 of the insertion section 144 is smaller than the width α2 of the engaging section 145. This allows the insertion section 144 to be inserted into the slot 184, and the slot 184 to be movable relative to the engaging structure 143, thereby moving the slot 184 from the insertion section 144 to the engaging section 145 and engaging with it. The width α2 of the engaging section 145 is smaller than the width α1 of the engaging plate 141, allowing the engaging plate 141 to limit the movement of the connector 180.

[0073] Additionally, please see Figure 12 and Figure 13 To ensure a more stable and reliable fit between the engaging structure 143 and the slot 184, the slot 184 can include a first sub-slot 185 that engages with the engaging plate 141, and a second sub-slot 186 that engages with the connecting arm 142. The first sub-slot 185 and the second sub-slot 186 are connected. Optionally, the width b1 of the first sub-slot 185 is greater than the width b2 of the second sub-slot 186, meaning the slot 184 is a T-shaped slot.

[0074] Optionally, please refer to Figure 13The width b1 of the first sub-groove 185 is greater than the width α2 of the engaging section 145 and less than the width α1 of the engaging plate 141. The engaging structure 143 is a wedge-shaped notch formed on the engaging plate 141. The width α1 of the engaging plate 141 is greater than the width of the engaging structure 143, and therefore the width α1 of the engaging plate 141 is greater than the widths of the engaging section 145 and the insertion section 144. If the width b1 of the first sub-groove 185 is less than the width α2 of the engaging section 145, the engaging section 145 will have difficulty engaging into the first sub-groove 185; while if the width b1 of the first sub-groove 185 is greater than the width α1 of the engaging plate 141, the engaging plate 141 will not be able to limit the fixing member 130, meaning the engaging structure 143 cannot engage and be fixed within the engaging groove 184. Therefore, by making the width b1 of the first sub-slot 185 greater than the width α2 of the engaging section 145 and less than the width α1 of the engaging plate 141, it can be ensured that the engaging section 145 can be well engaged and fixed with the slot 184.

[0075] And / or, the width b2 of the second sub-slot 186 is greater than the width α3 of the insertion segment 144 and less than the width α2 of the engaging segment 145. If the width b2 of the second sub-slot 186 is less than the width α3 of the insertion segment 144, it will be difficult for the insertion segment 144 to be inserted into the second sub-slot 186. If the width b2 of the second sub-slot 186 is greater than the width α2 of the engaging segment 145, it will be easy for the engaging segment 184 to detach from the engaging structure 143, preventing the engaging structure 143 from properly engaging and securing with the engaging segment 184. Therefore, the width b2 of the second sub-slot 186 being greater than the width α3 of the insertion segment 144 and less than the width α2 of the engaging segment 145 ensures that the engaging structure 143 and the engaging segment 184 can be engaged and secured together.

[0076] Therefore, by reasonably limiting the dimensions of the engaging structure 143 and the slot 184, it is convenient to assemble and fix the engaging structure 143 and the slot 184, and on the other hand, it can effectively improve the assembly stability and reliability of the engaging structure 143 and the slot 184.

[0077] Please see Figure 10Furthermore, the engaging structure 143 also includes a guide section 146, which connects the insertion section 144 and the engaging section 145. The width of the guide section 146 gradually increases from the insertion section 144 to the engaging section 145. Thus, by providing the guide section 146, the slot 184 can easily move from the insertion section 144 to the engaging section 145 and engage and be fixed with it.

[0078] Please see Figure 11 and Figure 12 In one embodiment, the second connecting portion 182 is screwed to the second fixing portion 150. Specifically, the second fixing portion 150 is provided with a first fixing hole, and the second connecting portion 182 is provided with a positioning portion 187. The positioning portion 187 is provided with a second fixing hole 188 corresponding to the first fixing hole. By inserting screws into the first fixing hole and the second fixing hole 188, the second connecting portion 182 is fixed to the first fixing portion 140, thereby strengthening the connection between the connecting member 180 and the fixing member 130.

[0079] Please see Figures 16 to 19 In another embodiment, the second connecting portion 182 is engaged with the first fixing portion 140. Specifically, the second connecting portion 182 has a groove 189 on the side near the second fixing portion 150, and the second fixing portion 150 engages within the groove 189. By engaging and fixing the second connecting portion 182 with the second fixing portion 150, the connection strength between the connecting member 180 and the fixing member 130 can be further improved.

[0080] In one embodiment, the first fixing part 140 and / or the second fixing part 150 extend along the height direction of the switch door 120. Optionally, both the first fixing part 140 and the second fixing part 150 extend along the height direction of the switch door 120, which can further improve the overall structural strength of the switch door 120, and at the same time improve the connection strength between the fixing member 130 and the switch door 120, preventing the fixing member 130 from breaking or being damaged.

[0081] Please see Figure 11In this embodiment, there are two first fixing parts 140, each located on one side of the second fixing part 150. Thus, by connecting the two first fixing parts 140 and the second fixing part 150 to the connector 180, the connection between the connector 180 and the fixing part 130 is stronger, thereby facilitating the drive assembly 160 to drive the door 120 to move and open or close the air outlet 115. Of course, in other embodiments, there may be only one first fixing part 140; the number of first fixing parts 140 is not specifically limited here.

[0082] Please see again Figure 3 and Figure 6 In one embodiment, there are two drive components 160, one of which is located at the upper end of the body 110 and the other is located at the middle of the body 110.

[0083] For ease of description, the drive assembly 160 located at the upper end of the fuselage 110 can be defined as the first drive assembly 160a, and the drive assembly 160 located in the middle of the fuselage 110 can be defined as the second drive assembly 160b. In one embodiment, when the connector 180 of the first drive assembly 160a engages with the engaging structure 143 of the fixing member 130, the upper surface of the second connecting portion 182 abuts against the engaging plate 141. When the connector 180 of the second drive assembly 160b engages with the engaging structure 143 of the fixing member 130, the upper surface of the second connecting portion 182 is spaced apart from the engaging plate 141 (e.g., ...). Figure 18 As shown in the figure, that is, the distance d between the upper surface of the second connecting part 182 and the locking plate 141 is greater than 0, which can further ensure that the fixing part 130 of the first driving component 160a and the corresponding second connecting part 182 can be assembled in place.

[0084] Please see Figure 14 , Figure 15 and Figure 20 In one embodiment, the drive mechanism 170 includes a drive motor 171, a gear 172 and an arc rack 173. The drive motor 171 is installed inside the body 110. The gear 172 is connected to the drive shaft of the drive motor 171. The arc rack 173 is connected to the first connecting part 181 and meshes with the gear 172.

[0085] In this embodiment, the drive motor 171 rotates via a drive gear 172, which meshes with the arc-shaped rack 173, thereby causing the connecting member 180 to rotate. The rotation of the connecting member 180 then drives the door 120 to move. This driving method ensures that the door 120 can move smoothly with low noise.

[0086] Optionally, the drive assembly 160 further includes a drive housing 174, on which the drive mechanism 170 is mounted. Considering that the first connecting portion 181 is connected to the arc-shaped rack 173, and the arc-shaped rack 173 is located within the drive housing 174, a clearance groove 175 can be provided on the drive housing 174. The first connecting portion 181 extends into the drive housing 174 via the clearance groove 175 and connects to the arc-shaped rack 173. The first connecting portion 181 can move within the clearance groove 175, and the clearance groove 175 can provide clearance for the first connecting portion 181.

[0087] Please see Figure 15 To better drive the door 120 to move along a preset trajectory, a first guide groove 176 can be provided on the drive box 174, and a sliding block can be provided on the arc-shaped rack 173, the sliding block being slidably installed within the first guide groove 176. Furthermore, to allow the connector 180 to rotate more smoothly with the rotation of the arc-shaped rack 173, a second guide groove 177 can be provided on the drive box 174, and a rolling element 178 can be provided within the second guide groove 177, the rolling element 178 engaging with the first connecting portion 181 of the connector 180. This reduces the contact friction between the connector 180 and the drive box 174, while increasing the support force on the connector 180, thereby ensuring that the connector 180 can move more smoothly and stably.

[0088] Please see again Figure 3 In one embodiment, the number of the clearance openings 114 is two, and each clearance opening 114 corresponds one-to-one with the drive assembly 160. To further prevent the clearance openings 114 from exposing the messy structure inside the housing 111, a shielding structure 190 can be provided on the housing 111. The housing 111 includes a bottom plate 1123, a top plate 1121, and a side plate 1122 connecting the bottom plate 1123 and the top plate 1121. The top plate 1121 and / or the side plate 1122 are provided with shielding structures 190 (e.g., Figure 21 and Figure 22 As shown in the figure, the shielding structure 190 is disposed opposite to the clearance opening 114 to shield the clearance opening 114.

[0089] Specifically, the shielding structure 190 is a shielding plate located inside the housing 111 and opposite the clearance opening 114, thus shielding the internal structure of the housing 111. In this embodiment, by providing the shielding structure 190, the clearance opening 114 can be blocked, preventing the user from seeing the messy internal structure of the housing 111. Furthermore, it can prevent external dust, insects, and other debris from entering the drive mechanism 170.

[0090] Please see again Figure 1 , Figure 2 and Figure 3 The unit has two air outlets 115, each located on one side of the housing 111. Correspondingly, it also has two doors 120: a left door 120a and a right door 120b, each corresponding to one of the two air outlets 115. In this embodiment, by providing two air outlets 115, the air volume and air delivery range can be increased, thereby improving the user comfort of the indoor unit 100.

[0091] Accordingly, there are two of each of the first drive component 160a and the second drive component 160b. The two first drive components 160a are respectively configured for the two air outlets 115, and the two second drive components 160b are respectively configured for the two air outlets 115. The two first drive components 160a can be configured independently or connected together, depending on actual needs. Similarly, the two second drive components 160b can be configured independently or connected together, depending on actual needs.

[0092] In one embodiment, the indoor unit 100 of the air conditioner can be a main unit and a sub-unit, that is, the indoor unit 100 of the air conditioner includes a main unit and a sub-unit. The main unit is provided with a receiving cavity 116, and the sub-unit is detachably installed in the receiving cavity 116, that is, the sub-unit can be separated from the body 110, and the body 110 is the main unit body 110.

[0093] Please see again Figure 3The lower part of the unit 110 is provided with a receiving cavity 116, which has a forward-facing opening. The sub-unit is housed within the receiving cavity 116 and can be moved out through the opening. It is understood that the sub-unit can be manually removed from the receiving cavity 116 by the user, or it can be moved out of the receiving cavity 116 by a control device without manual operation. After the sub-unit is removed, it can autonomously circulate and operate independently within the room to meet the overall indoor air treatment needs. Alternatively, the user can manually move the sub-unit to a desired location within the room, such as a densely populated area, to provide targeted air supply to a specific area, achieving long-distance, targeted, and directional air supply and improving air treatment efficiency. Compared to the entire floor-standing indoor air conditioning unit 100, this sub-unit is more flexible and convenient to move, thus meeting different user air treatment needs. It is understood that the air conditioner indoor unit 100 also includes a door 117, which is installed at the opening of the receiving cavity 116 to open or close the opening of the receiving cavity 116.

[0094] The sub-unit is mainly used for air treatment, such as, but not limited to, purification, humidification, dehumidification, sterilization, and dehumidification. The sub-unit includes at least one air treatment module. It should be noted that at least two air treatment modules can be of the same type and function, or they can be different. Optionally, the air treatment module includes one or more combinations of a humidification module, a purification module, a sterilization module, and a dehumidification module. The purification module includes one or more combinations of a filter module, an electrostatic dust collection module, a negative ion module, and a plasma module. Specifically, the filter module may include one or more combinations of HEPA filters, activated carbon filters, plasma integrated mesh, photocatalytic filters, and formaldehyde filters.

[0095] The present invention also proposes an air conditioner, which includes an outdoor unit and an indoor unit 100.
