[0039] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0040] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0041] The air conditioner 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0042] like Figures 1 to 8As shown, the air conditioner 100 according to the embodiment of the utility model, including: air duct subassembly 1 and negative ion generator 4, air duct subassembly 1 is equipped with connecting column 2 and positioning structure 3, negative ion generator 4 is located in air duct subassembly 1, negative ion generator 4 is connected with connecting column 2 along the first direction e1 by fastener 5, positioning structure 3 is at least used to limit the activity freedom degree of negative ion generator 4 in the second direction e2 and third direction e3, the second direction e2 and third direction e3 are perpendicular with the first direction e1 and the second direction e2 is perpendicular with third direction e3.

[0043] Therefore, in the process of installing negative ion generator 4 to air duct subassembly 1, after the cooperation of negative ion generator 4 and positioning structure 3, the position of negative ion generator 4 on air duct subassembly 1 can be better maintained by positioning structure 3 to avoid the movement of negative ion generator 4 along the second direction e2 and third direction e3, so that negative ion generator 4 does not need to be held during the process of fixing negative ion generator 4 to connecting column 2 by fastener 5, and positioning between negative ion generator 4 and connecting column 2 can be realized to improve the installation efficiency of negative ion generator 4 while ensuring the installation accuracy of negative ion generator 4. And it can be understood that negative ion generator 4 can be connected with connecting column 2 along the first direction e1 by fastener 5, so that negative ion generator 4 can limit the movement of negative ion generator 4 in the first direction e1, the second direction e2 and the third direction e3 by cooperating with connecting column 2 and positioning structure 3 to improve the stability of negative ion generator 4 after installation.

[0044] Specifically, taking air conditioner 100 as a hanging machine and the first direction e1 as a horizontal direction as an example, air duct subassembly 1 is a bottom plate, the activity freedom degree of negative ion generator 4 in the front-back-up-down direction can be limited by positioning structure 3, and negative ion generator 4 can be prevented from rotating clockwise or counterclockwise around the center axis during installation, so that negative ion generator 4 can be kept in the position assembled with connecting column 2 to facilitate the subsequent fixation of negative ion generator 4 on connecting column 2 by fastener 5. It should be noted that this is only an example of one type of air conditioner 100 and one installation orientation of negative ion generator 4, and is not a limitation on the type of air conditioner 100 and the installation orientation of negative ion generator 4, such as cabinet machine, window type, etc.

[0045] According to the air conditioner 100 of the embodiment of the utility model, through the positioning structure 3 can better keep the position of the negative ion generator 4 on the air duct assembly 1, to avoid the negative ion generator 4 along the second direction e2 and third direction e3 moves, so that can not need to hold the negative ion generator 4 in the process of fixing the negative ion generator 4 to the connecting column 2 through the fastener 5, can realize the positioning between the negative ion generator 4 and the connecting column 2 simultaneously, to improve the installation efficiency of the negative ion generator 4 while guaranteeing the installation precision of the negative ion generator 4.

[0046] According to some embodiments of the utility model, the positioning structure 3 includes a plurality of positioning sub-structures arranged on the outer circumferential side of the negative ion generator 4 along the circumference of the negative ion generator 4, each positioning sub-structure is used for limiting the movement of the negative ion generator 4 towards the outside of the positioning sub-structure. Wherein, the outer circumferential side of the negative ion generator 4 refers to the outside of the negative ion generator 4 in the second direction e2 and the third direction e3, and the outside of the positioning sub-structure refers to the side of the positioning sub-structure facing away from the negative ion generator 4 in the second direction e2 or the third direction e3. Therefore, the positioning sub-structure located on one side of the negative ion generator 4 in the second direction e2 can limit the freedom of movement of the negative ion generator 4 in the second direction e2, and the positioning sub-structure located on one side of the negative ion generator 4 in the third direction e3 can limit the freedom of movement of the negative ion generator 4 in the third direction e3. Thus, through a plurality of positioning sub-structures, the positioning position of the negative ion generator 4 by the positioning structure 3 can be increased, for example, the opposite sides of the negative ion generator 4 in the second direction e2 and the opposite sides of the negative ion generator 4 in the third direction e3 are provided with positioning sub-structures, so that the reliability of the positioning of the negative ion generator 4 by the positioning structure 3 can be improved.

[0047] According to some embodiments of the utility model, the negative ion generator 4 includes a generator body 41 and an emission head 42 provided on the generator body 41, and the plurality of positioning sub-structures include a first positioning sub-structure and a second positioning sub-structure. The first positioning sub-structure is used for limiting the emission head 42, and the second positioning sub-structure is used for limiting the generator body 41. That is, the position of the emission head 42 on the air duct assembly 1 can be better limited by the first positioning sub-structure, so that the limitation of the negative ion generator 4 is realized by limiting the emission head 42, and the position of the generator body 41 on the air duct assembly 1 can be better limited by the second positioning sub-structure, so that the limitation of the negative ion generator 4 is realized by limiting the generator body 41. That is, the emission head 42 and the generator body 41 of the negative ion generator 4 are positioned by the corresponding positioning sub-structure, so that the reliability of the positioning of the negative ion generator 4 by the positioning structure 3 can be improved.

[0048] According to some embodiments of the present application, the generator body 41 and the emission head 42 are arranged along the second direction e2, and in the second direction e2, the first positioning sub-structure is located at one end of the generator body 41 facing the emission head 42, and the second positioning sub-structure is located at one end of the generator body 41 away from the emission head 42. That is, the first positioning sub-structure for limiting the emission head 42 and the second positioning sub-structure for limiting the generator body 41 are respectively located at opposite ends of the generator body 41 in the second direction e2. Therefore, the distance between the first positioning sub-structure and the second positioning sub-structure can be increased, thereby reducing the production and processing difficulty of the first positioning sub-structure and the second positioning sub-structure, and reducing the matching difficulty of the negative ion generator 4 with the first positioning sub-structure and the second positioning sub-structure respectively. At the same time, the first positioning sub-structure and the second positioning sub-structure can respectively limit the two ends of the negative ion generator 4 in the second direction e2, so that the limiting effect of the positioning structure 3 on the negative ion generator 4 can better cover the negative ion generator 4, thereby improving the reliability of the positioning structure 3 in positioning the negative ion generator 4.

[0049] According to some embodiments of the present application, the second positioning sub-structure is a positioning rib 31 provided on the air duct assembly 1, and at least part of the positioning rib 31 is located on the outer circumferential side of the generator body 41 and is arranged opposite to the outer circumferential surface of the generator body 41. Wherein, the outer circumferential surface of the generator body 41 here refers to the outer side surface of the generator body 41 in the second direction e2 and the third direction e3. That is, through the opposite part of the positioning rib 31 and the outer circumferential surface of the negative ion generator 4, the movement of the negative ion generator 4 towards the outside of the positioning rib 31 can be better limited, and the outside of the positioning rib 31 here refers to the side of the positioning rib 31 away from the negative ion generator 4 in the second direction e2 or the third direction e3, thereby at least limiting the activity freedom of the negative ion generator 4 in the second direction e2 and / or the third direction e3. Wherein, since the positioning rib 31 has simple structure and good limiting effect, the structure complexity of the positioning structure 3 can be simplified while ensuring the limiting effect of the positioning rib 31 on the negative ion generator 4, thereby reducing the processing and forming difficulty of the positioning structure 3.

[0050] According to some embodiments of the present application, the part of the positioning rib 31 opposite to the outer circumferential surface of the generator body 41 is a positioning part, and the size of the positioning part in the first direction e1 is not less than 3mm. That is, the limiting length of the positioning rib 31 to the negative ion generator 4 in the first direction e1 is not less than 3mm. It can be understood that the larger the size of the positioning part in the first direction e1, the better the limiting effect of the positioning rib 31 to the negative ion generator 4. Thus, the limiting effect of the positioning rib 31 to the negative ion generator 4 can be better guaranteed. For example, the size of the positioning part in the first direction e1 can be 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, etc., which is not specifically limited here.

[0051] According to some embodiments of the present application, the size of the positioning part in the first direction e1 ranges from 4mm to 4.5mm. That is, the length of the positioning rib 31 limiting the negative ion generator 4 in the first direction e1 is controlled in the range of 4mm to 4.5mm, which can control the length of the positioning rib 31 in the first direction e1 while guaranteeing the limiting effect of the positioning rib 31 to the negative ion generator 4. For example, the size of the positioning part in the first direction e1 can be 4mm, 4.1mm, 4.2mm, 4.3mm, 4.4mm, 4.5mm, etc., which is not specifically limited here.

[0052] According to some embodiments of the present application, the interval between the positioning rib 31 and the generator body 41 ranges from 0.5mm to 1mm. That is, the outer circumferential surface of the positioning rib 31 and the generator body 41 are separated by an interval of 0.5mm to 1mm along the second direction e2 and / or the third direction e3, such as the positioning rib 31 located on one side of the generator body 41 in the second direction e2 and the generator body 41 in the second direction e2. The interval ranges from 0.5mm to 1mm, and the positioning rib 31 located on one side of the generator body 41 in the third direction e3 and the generator body 41 in the second direction e2. The interval ranges from 0.5mm to 1mm. It can be understood that the closer the distance between the positioning rib 31 and the generator body 41, the better the limiting effect of the positioning rib 31 to the generator body 41, but the more likely the generator body 41 to rub against the positioning rib 31 when installed between the plurality of positioning ribs 31. Conversely, the farther the distance between the positioning rib 31 and the generator body 41, the worse the limiting effect of the positioning rib 31 to the generator body 41, but the less likely the generator body 41 to rub against the positioning rib 31 when installed between the plurality of positioning ribs 31.

[0053] Therefore, by controlling the interval between the positioning ribs 31 and the generator body 41 in the range of 0.5mm to 1mm, the predetermined positioning effect of the positioning ribs 31 on the generator body 41 can be ensured, while avoiding friction between the negative ion generator 4 and the positioning ribs 31 during installation, and providing a certain margin space for the production tolerance of the positioning ribs 31 and the negative ion generator 4 to ensure that the negative ion generator 4 can be smoothly installed on the air duct assembly 1. The interval between the positioning ribs 31 and the generator body 41 can be 0.5mm, 0.55mm, 0.6mm, 0.65mm, 0.7mm, 0.75mm, 0.8mm, 0.85mm, 0.9mm, 0.95mm, 1mm, etc.

[0054] According to some embodiments of the present application, the generator body 41 is rectangular, and in the second direction e2, the emitting head 42 is arranged at one end of the generator body 41, and the two corner positions of the end of the generator body 41 away from the emitting head 42 are each provided with a positioning rib 31. The positioning rib 31 comprises a first rib section 311 and a second rib section 312. The first rib section 311 extends along the second direction e2, and the two first rib sections 311 are respectively located on opposite sides of the generator body 41 in the third direction e3. The second rib section 312 extends along the third direction e3 and is located on the side of the generator body 41 away from the emitting head 42 in the second direction e2. The connection position of the first rib section 311 and the second rib section 312 is located at the corner position of the generator body 41 away from the emitting head 42.

[0055] That is, the two first rib sections 311 on both sides can better limit the activity freedom of the generator body 41 in the third direction e3, and the second rib section 312 can better limit the activity freedom of the generator body 41 in the third direction e3. The two positioning ribs 31 are located at the two corner positions of the generator body 41, and the connection of the first rib section 311 and the second rib section 312 can better cover the two corner positions, which can improve the predetermined positioning effect of the two positioning ribs 31 on the generator body 41.

[0056] According to some embodiments of the present application, the first positioning sub-structure is a positioning hole 32 formed on the air duct assembly 1, and the emitting head 42 is arranged in the positioning hole 32. That is, when the negative ion generator 4 is installed on the air duct assembly 1, the emitting head 42 is aligned with the positioning hole 32 and inserted. Through the cooperation of the positioning hole 32 and the emitting head 42, the activity freedom of the negative ion generator 4 relative to the positioning column can be better limited, so that the activity freedom of the negative ion generator 4 relative to the air duct assembly 1 can be limited, and the positioning between the negative ion generator 4 and the connecting column 2 can be realized, so as to simplify the installation process of the negative ion generator 4 and improve the installation efficiency of the negative ion generator 4.

[0057] According to some embodiments of the present application, the air duct assembly 1 is formed with an airflow channel 11, the negative ion generator 4 is located outside the airflow channel 11, and the positioning hole 32 penetrates the air duct assembly 1 and communicates with the airflow channel 11. That is, the positioning hole 32 can be used as a channel for communication between the airflow channel 11 and the installation position of the negative ion generator 4 on the basis of positioning the emitting head 42, and the emitting head 42 can release negative ions into the airflow channel 11 through the positioning hole 32 to sterilize the airflow in the airflow channel 11. Therefore, the channel for releasing negative ions from the emitting head 42 into the airflow channel 11 is omitted, thereby simplifying the production and processing steps of the air duct assembly 1. In a specific example, the air duct assembly 1 is formed with an air outlet 12, and the air duct assembly 1 includes an air duct side plate located on one side of the air outlet 12 in the length direction, and the negative ion generator 4 is installed on the side of the air duct side plate 13 away from the air outlet 12, and the positioning hole 32 is provided on the air duct side plate 13 and penetrates the air duct side plate 13 in the thickness direction.

[0058] According to some embodiments of the present application, the depth of the emitting head 42 inserted into the positioning hole 32 is not less than 3mm. It can be understood that the deeper the depth of the emitting head 42 inserted into the positioning hole 32, the better the positioning effect of the positioning hole 32 on the emitting head 42. Thus, the positioning effect of the positioning hole 32 on the negative ion generator 4 can be ensured. For example, the depth of the emitting head 42 inserted into the positioning hole 32 can be 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, etc., which is not limited here.

[0059] According to some embodiments of the present application, the depth of the emitting head 42 inserted into the positioning hole 32 is in the range of 4-4.5mm. Thus, the length of the emitting head 42 in the first direction e1 can be controlled while ensuring the positioning effect of the positioning hole 32 on the emitting head 42. For example, the depth of the emitting head 42 inserted into the positioning hole 32 can be 4mm, 4.1mm, 4.2mm, 4.3mm, 4.4mm, 4.5mm, etc., which is not limited here.

[0060] According to some embodiments of the present application, the anion generator 4 is provided with a connecting lug 43 connected with the connecting column 2, the connecting lug 43 and the emitting head 42 are located on the same side of the generator body 41, and the emitting head 42 has two distributed on the opposite sides of the connecting lug 43. That is, the connecting lug 43 is connected between the two emitting heads 42, and the number of the positioning holes 32 and the emitting heads 42 can be the same and one-to-one corresponding arrangement, so that after the two emitting heads 42 are respectively inserted into the corresponding positioning holes 32, the limiting positions of the two positioning holes 32 on the anion generator 4 are distributed on the opposite sides of the connecting lug 43, so that the symmetry of the positioning structure 3 can be guaranteed. In addition, the distance between the position of the positioning hole 32 limiting the anion generator 4 and the connecting lug 43 can be shortened, so that through the cooperation of the emitting head 42 and the positioning hole 32, the positioning accuracy between the connecting lug 43 and the connecting column 2 can be improved, and the pre-positioning effect of the positioning structure 3 on the anion generator 4 can be improved.

[0061] According to some embodiments of the present application, the air duct assembly 1 is further provided with a support rib 6, and the support rib 6 is provided with at least two, and the at least two support ribs 6 are triangularly distributed with the connecting column 2, and the anion generator 4 is supported on the connecting column 2 and the support rib 6. Therefore, the connecting column 2 and the support rib 6 can form three-point support for the anion generator 4, so that the anion generator 4 can be prevented from swinging, and the pre-positioning effect of the positioning structure 3 on the anion generator 4 can be improved.

[0062] According to some embodiments of the present application, the connecting column 2 and the support rib 6 are located at opposite ends of the anion generator 4 in the second direction e2, and the plurality of support ribs 6 are arranged at intervals along the third direction e3. That is, one end of the anion generator 4 in the second direction e2 is supported on the connecting column 2, the other end of the anion generator 4 in the second direction e2 is supported on the plurality of support ribs 6, and the plurality of support ribs 6 can be supported at multiple positions of the anion generator 4 along the third direction e3. Therefore, the connecting column 2 and the plurality of support ribs 6 can better cover the anion generator 4, so that the stability of the connecting column 2 and the plurality of support ribs 6 supporting the anion generator 4 can be improved.

[0063] According to some embodiments of the present application, the positioning structure 3 comprises positioning ribs 31 distributed on the outer circumferential side of the negative ion generator 4, and the positioning ribs 31 are connected with the supporting ribs 6. Among them, the positioning ribs 31 and the supporting ribs 6 are both arranged on the air duct assembly 1, that is, the positioning ribs 31 and the supporting ribs 6 are both directly connected with the air duct assembly 1, the positioning ribs 31 are connected with the supporting ribs 6, so that the positioning ribs 31 are also connected with the air duct assembly 1 through the supporting ribs 6, and the supporting ribs 6 are also connected with the air duct assembly 1 through the positioning ribs 31, that is, the connecting positions of the supporting ribs 6 and the air duct assembly 1 can be increased through the positioning ribs 31, and the connecting positions of the positioning ribs 31 and the air duct assembly 1 can be increased through the supporting ribs 6, so that the connecting strength of the positioning ribs 31 and the supporting ribs 6 and the air duct assembly 1 can be improved.

[0064] According to some embodiments of the present application, the positioning structure 3 and the air duct assembly 1 are integrally formed. Thus, the integrally formed structure not only can ensure the structure and performance stability of the positioning structure 3 and the air duct assembly 1, but also is convenient to form and simple to manufacture, and the connecting parts and connecting procedures used between the positioning structure 3 and the air duct assembly 1 are omitted, the production cost is low, the assembly efficiency of the positioning structure 3 and the air duct assembly 1 is greatly improved, the connection reliability of the positioning structure 3 and the air duct assembly 1 is ensured, and in addition, the overall strength and stability of the integrally formed structure is higher, and the service life is longer.

[0065] In one specific example, the positioning structure 3 is in an axisymmetric structure, and the symmetry axis of the positioning structure 3 is parallel to the second direction e2 and passes through the center of the negative ion generator 4 in the third direction e3.
