Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioning indoor unit and an air conditioner. Background Art

[0002] In the prior art, there are more and more types of air conditioners, but the overall structure of the existing air conditioners on the market is relatively complex. After the air conditioner is used for a long time, the air duct part is relatively dirty and it is difficult for non-professionals to clean it. Summary of the invention

[0003] The problem solved by the present invention is that the overall structure of the existing air conditioners on the market is relatively complex, and after the air conditioners are used for a long time, the air duct part is relatively dirty and it is difficult for non-professionals to clean it.

[0004] To solve the above problems, the present invention provides an air-conditioning indoor unit, comprising an evaporator, a water receiving tray and an air duct component, wherein the evaporator is arranged above the water receiving tray, and the air duct component is located below the water receiving tray, and the air duct component can be detachably installed in the body of the air-conditioning indoor unit; the air duct component can be directly pulled out from the body of the air-conditioning indoor unit.

[0005] Therefore, the air duct component can be detachably installed inside the body of the air conditioner indoor unit through the air duct installation structure, and when cleaning, the air duct component can be directly pulled out, and after cleaning, it can be directly installed by aligning it with the disassembly port, which is convenient for users to clean by themselves.

[0006] Furthermore, the air duct component is also provided with an outer plate, the outer plate is connected to a side of the air duct component away from the inside of the body of the air conditioner indoor unit, and the outer plate is used to cover the air duct component.

[0007] Therefore, the outer plate is used to cover the air duct component, on the one hand to prevent air leakage, and on the other hand for aesthetics.

[0008] Furthermore, at least one buckle is provided on a side of the outer plate away from the air duct component, and the buckle is used to pull out the air duct component.

[0009] Thereby, it is convenient to draw out the air duct component from the body of the indoor unit of the air conditioner.

[0010] Furthermore, a buckle portion is provided at the bottom of the air duct component and a bayonet portion is provided on the bottom plate of the air conditioner indoor unit; the buckle portion is adapted to the shape of the bayonet portion; and the buckle portion is suitable for being inserted into the bayonet portion, and when the air duct component is pulled out, the buckle portion is suitable for being detached from the bayonet portion.

[0011] Therefore, through the cooperation of the buckle part set at the bottom of the air duct component and the bayonet part set on the bottom plate of the air-conditioning indoor unit, the air duct component can be directly pulled out from the air-conditioning indoor unit body. Since the shapes of the buckle part and the bayonet part are adapted, when the air duct component is installed, it is directly pushed into the body of the air-conditioning indoor unit, and the buckle part automatically engages with the bayonet part to fix it. When the air duct component is pulled out, the buckle part can be directly separated from the bayonet part by the action of external force. The air duct component can make the installation and disassembly of the air duct component and the air-conditioning indoor unit relatively simple, so that the user can install and disassemble it by themselves, and clean it after disassembly.

[0012] Furthermore, the buckle portion includes a buckle head, a buckle body and a buckle tail which are connected in sequence; the buckle head, the buckle body and the buckle tail are all fixedly connected to the bottom of the air duct component.

[0013] This prevents the buckle portion from being damaged after long-term use.

[0014] Furthermore, the buckle head is in a bullet shape, the buckle body is in a waist shape, and the buckle tail is in a square shape.

[0015] Therefore, the bullet-shaped buckle head makes it very easy for the buckle part to enter the bayonet part; the waist-shaped buckle body is convenient for limiting the movement of the buckle head, and the square buckle tail is convenient for fixing.

[0016] Furthermore, the buckle head and / or the buckle body and / or the buckle tail are hollow structures.

[0017] As a result, the hollow structure can reduce the overall weight of the air duct components, making it easier for customers to clean them.

[0018] The bayonet portion includes two relatively symmetrically arranged fixing plates, the fixing plates are fixedly connected to the bottom plate, and the distance between the two fixing plates can accommodate the buckle portion.

[0019] Thus, the buckle portion is fixed by the two fixing plates to prevent the air duct component from shaking, and when the air duct component is pulled out, the buckle portion can be disengaged from between the two fixing plates.

[0020] Furthermore, the fixing plate includes two flat plates and a positioning plate; the positioning plate is located between the two flat plates, and the shape of the positioning plate is adapted to the shape of the buckle body.

[0021] Thus, the two flat plates facilitate the fixation of the buckle portion after it enters, and the positioning plate facilitates the prevention of movement of the buckle head.

[0022] Furthermore, an opening is provided on one side of the positioning plate close to the bottom plate.

[0023] Thus, the friction resistance between the buckle portion and the positioning plate is reduced.

[0024] Furthermore, the number of the buckle parts and the bayonet parts is more than two, and the more than two buckle parts and the bayonet parts are evenly distributed on the bottom of the air duct component and the bottom plate, respectively.

[0025] Thus, the two or more buckle parts and the bayonet parts can not only jointly and balancedly support the weight of the air duct component, but also make the buckle parts and the bayonet parts firmly fixed.

[0026] Compared with the prior art, the air duct component of the present invention can be drawn out from the interior of the indoor unit body and cleaned by the user, thereby avoiding the difficulty that the air duct component is dirty and can only be cleaned by professionals.

[0027] In order to solve the above technical problems, the present invention further provides an air conditioner, comprising the above-mentioned air conditioner indoor unit.

[0028] Other advantages of the air conditioner described in the present invention over the prior art are the same as the advantages of the air conditioner indoor unit over the prior art, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The accompanying drawings illustrate specific embodiments of the present invention in detail.

[0045] In the description of the present invention, it should be understood that the positive direction of "X" in the drawings represents the front, and correspondingly, the reverse direction of "X" represents the rear; the positive direction of "Y" represents the right, and correspondingly, the reverse direction of "Y" represents the left; the positive direction of "Z" represents the top, and correspondingly, the reverse direction of "Z" represents the bottom. The orientation or position relationship indicated by the terms "X", "Y", "Z", etc. is based on the orientation or position relationship shown in the drawings of the specification, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. The description of the term "some specific embodiments" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same implementation or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0046] like Figure 1-13As shown, an indoor air conditioner includes an evaporator 4, a water tray 5 and an air duct component 1. The evaporator 4 is arranged above the water tray 5, and the air duct component 1 is located below the water tray 5. The air duct component 1 can be detachably installed in the body of the indoor air conditioner; the air duct component 1 can be directly drawn out of the body of the indoor air conditioner. The air duct component 1 of this embodiment can be drawn out from the inside of the indoor air conditioner body and cleaned by the user, thereby avoiding the difficulty that the air duct component can only be cleaned by professionals when it is dirty.

[0047] like Figure 2 , 3 As shown in Figure 4, the water receiving tray 5 of this embodiment can be fixed on the top of the air duct component 1 in any detachable manner. The detachable manner makes the installation and removal of the water receiving tray 5 more convenient, and the water receiving tray 5 is located above the air duct component 1, which can separate the evaporator 4 and the air duct component 1 in two different cavities, which can reduce the air flow velocity, make the air flow heat exchange more sufficient and more uniform, improve the heat exchange efficiency, and thus improve the cooling or heating effect of the air conditioner.

[0048] like Figure 4 As shown, the water receiving tray 5 is provided with a hollow structure, and the hollow structure is suitable for supplying air to the air duct component 1. The hollow structure can be arranged along a width direction parallel to the water receiving tray 5, or can be arranged along a length direction parallel to the water receiving tray 5. One or more hollow structures can be arranged, and the shape of the hollow structure can be circular, rectangular, triangular, or various shapes combined therefrom.

[0049] Specifically, in this embodiment, the hollow structure is integrally formed with the water receiving tray 5, and there are two hollow structures. Both hollow structures are rectangular and are arranged along the length direction parallel to the water receiving tray 5, thereby reducing the span of the hollow structure, which can improve the structural strength of the water receiving tray 5. At the same time, the hollow structure and the plate body water receiving tray are integrally formed to save costs. Therefore, by arranging the hollow structure on the plate body water receiving tray 5, it is convenient to take in air. It should be noted that the evaporator 4 is located above the water receiving tray 5, and the evaporator 4 can be fixed. The specific fixing method can be set by oneself, and this embodiment will not be elaborated in detail here. As long as the evaporator 4 can be arranged above the water receiving tray 5, it is sufficient.

[0050] In some specific embodiments, the air duct component 1 is further provided with an outer plate 12, which is connected to a side of the air duct component 1 away from the body of the air conditioner indoor unit, and is used to cover the air duct component 1. Since the front panel may not be provided in this embodiment, when the front panel is not provided, the outer plate 12 in this embodiment is used to match the shape of other external shells when the air duct component 1 is inside the body of the air conditioner indoor unit, and the appearance is very beautiful even without the front panel. Each side of the outer plate 12 of the present application can also be tightly fitted with the corresponding outer shell to prevent the airflow in the air duct component from overflowing from the periphery of the outer plate 12.

[0051] like Figure 7 As shown, Figure 7 It is a structural schematic diagram of the air duct component; a handle 121 is also provided on the side of the outer plate 12 away from the air duct component 1, so as to facilitate the extraction of the air duct component 1; preferably, there are two handles 121, and the two handles 121 are symmetrically provided on the left and right sides of the outer plate 12; when the air duct component 1 is extracted, both left and right hands can be used at the same time to reduce the force used by the user.

[0052] More specifically, a buckle portion 11 is provided at the bottom of the air duct component 1 and a bayonet portion 21 is provided on the bottom plate 2 of the air conditioner indoor unit; the buckle portion 11 is adapted to the shape of the bayonet portion 21; and the buckle portion 11 is suitable for being snapped into the bayonet portion 21, and when the air duct component 1 is pulled out, the buckle portion 11 is suitable for being detached from the bayonet portion 21.

[0053] like Figure 5 , 6 , as shown in 11, Figure 5 This is a schematic diagram of the structure after the air duct components are pulled out from the air conditioner indoor unit body. Figure 6 for Figure 5 Bottom view of Fig.11 The figure is a cross-sectional view after the buckle part 11 is inserted into the bayonet part 21; the buckle part 11 is arranged at the bottom of the air duct component 1, and is engaged with the bayonet part 21 arranged on the bottom plate 2 of the air conditioner indoor unit. Since the positions of the buckle part 11 and the bayonet part 21 correspond to each other, when the air duct component 1 is installed, the air duct component 1 can be directly pushed into the air conditioner indoor unit body, and the bayonet part 21 engages the buckle part 11. When disassembling, the buckle part 11 can be directly pulled out with force to separate the bayonet part 21, so that the air duct component 1 can be pulled out from the air conditioner indoor unit body. The air duct installation structure of the air duct component 1 and the air conditioner indoor unit can make the installation and disassembly of the air duct component and the air conditioner indoor unit relatively simple, so that the user can install and disassemble by himself, and clean it after disassembly.

[0054] Preferably, there are multiple buckle parts 11 and bayonet parts 21, and multiple buckle parts 11 are evenly arranged at the bottom of the air duct component 1, and multiple bayonet parts 21 are arranged on the bottom plate 2, and the positions of the bayonet parts 21 and the buckle parts 11 correspond one to one, so that they jointly support the weight of the air duct component 1, which is convenient for disassembly; preferably, the number of buckle parts 11 and bayonet parts 21 is 4, and the number of 4 buckle parts 11 and bayonet parts 21 is a more appropriate number in this embodiment, which can easily remove the air duct component 1 from the air-conditioning indoor unit during disassembly, and the number of 4 buckle parts 11 and bayonet parts 21 is only suitable for the air duct component 1 described in the present invention. The specific number of buckle parts 11 and bayonet parts 21 can be set according to the size and model of the air conditioner, as long as it can meet the requirements of supporting the weight of the air duct component 1 and can be engaged with the bayonet part 21 set on the bottom plate 2 of the air-conditioning indoor unit. More preferably, the buckle portion 11 and the bayonet portion 21 are made of plastic material. The buckle portion 11 made of plastic material can not only reduce the weight of the air duct component 1, but also prevent deformation after long-term use.

[0055] In some specific embodiments, the buckle portion 11 includes a buckle head 111, a buckle body 112 and a buckle tail 113 which are connected in sequence; the buckle head 111, the buckle body 112 and the buckle tail 113 are all fixedly connected to the bottom of the air duct component 1, thereby further ensuring the firmness of the buckle portion 11, which is not easily damaged even after long-term use.

[0056] More specifically, Fig.12 As shown, Fig.12The upper middle side is a schematic diagram of the structure of the bayonet portion 21, and the lower side is a schematic diagram of the structure of the buckle portion 11; the buckle head 111 is in the shape of a bullet, and the bullet-shaped buckle head 111 can easily enter the bayonet portion 21 when it is engaged with the bayonet portion 21. Of course, the bullet-shaped buckle head 111 is the best shape of this embodiment, for example: any buckle head with a slightly smaller arc shape that can easily enter the bayonet portion 21 is acceptable. The buckle body 112 is in the shape of a waist, and the so-called waist is similar to the shape of the human body S waist; the waist-shaped buckle body 112 can play a role of engaging with the bayonet portion 21 after the buckle head 111 enters, preventing the buckle head 111 from detaching, and can also play a role of limiting after the buckle head 111 enters a certain distance. In this embodiment, the waist-shaped buckle body 112 is the best shape of the present invention. Of course, other shapes of buckle bodies 112 are acceptable, as long as they can be connected to the buckle head 111 and play the same role. The buckle tail 113 is in the shape of a square. The square buckle tail 113 can further prevent the buckle head 111 from entering the slot. When the buckle head 111 reaches the specified position, the buckle body 112 is first fixed by the initial limit, and the square buckle tail 113 is finally fixed. The square buckle tail 113 in this embodiment is only the best shape, and any shape that can be connected to the buckle body 112 and play a fixed limit role can be used.

[0057] It should be noted that the shape of the buckle portion 11 is the best shape of the present invention, and any shape that can be engaged with the bayonet portion 21 so that the air duct component 1 can be pulled out from the air conditioner indoor unit body is acceptable.

[0058] like Fig.10 As shown, Fig.10 The bottom view of the air duct component; the buckle head 111 and / or the buckle body 112 and / or the buckle tail 113 are hollow structures. Preferably, the buckle head 111, the buckle body 112 and the buckle tail 113 are all hollow structures. Since the buckle part 11 is fixedly connected to the air duct component 1, the hollow structure can reduce the weight of the air duct component 1 and facilitate disassembly and installation.

[0059] The bayonet portion 21 includes two relatively symmetrically arranged fixing plates 211 . The fixing plates 211 are fixedly connected to the bottom plate 2 , and the distance between the two fixing plates 211 can accommodate the buckle portion 11 .

[0060] After the buckle portion 11 enters the bayonet portion 21, the air duct component 1 is prevented from shaking in the indoor unit body by being fixed by the fixing plate 211. If the distance between the two fixing plates 211 is too large, when the air conditioner is running, the air duct component 1 will shake due to the rotation of the fan, thereby generating noise. If the distance between the two fixing plates 211 is too narrow, the buckle portion 11 cannot be installed.

[0061] Preferably, the height of the fixing plate 211 (ie, the distance to the bottom plate 2 ) is the same as the height of the buckle portion 11 , so that the fixing plates 211 on both sides of the buckle portion 11 and the buckle portion 11 can support the weight of the air duct component 1 together.

[0062] like Fig.12 , 13 As shown, Fig.13 for Fig.12 A partial schematic diagram of the middle M-shaped bayonet portion 21; the fixing plate 211 includes two flat plates 2111 and a positioning plate 2112; the positioning plate 2112 is located between the two flat plates 2111, and the positioning plate 2112 is waist-shaped. When installing, the buckle head 111 first enters the bayonet portion 21, and then the buckle body 112 enters. After the buckle head 111 enters the specified position, the positioning plate 2112 limits the buckle body 112 from continuing to move forward through the action of the positioning plate 2113 until the buckle tail 113 is completely fixed. The waist-shaped positioning plate 2113 has the same shape as the buckle body 112, and the purpose is that after the buckle portion 11 reaches the position, the end of the positioning plate 2113 away from the buckle head 111 limits the position of the buckle portion 11; in order to prevent the buckle portion 11 from sliding toward the outside, the waist-shaped positioning plate 2112 is limited at one end close to the buckle head 111.

[0063] The positioning plate 2112 is also provided with an opening on one side close to the bottom plate 2, and the opening can reduce the friction between the positioning plate 2112 and the buckle portion 11, and facilitate the disassembly and installation of the buckle portion 11 and the bayonet portion 21. It should be noted that the shape of the opening can be any shape, as long as it can reduce the friction between the positioning plate 2112 and the buckle portion 11 and fix the buckle portion 11.

[0064] The buckle part 11 and the bayonet part 21 are both made of plastic material, and the whole disassembly process of the present invention does not require a screw, and is completely realized by the plastic buckle. Therefore, non-professionals can clean the air conditioner internal unit through simple operation.

[0065] The present invention also provides an air conditioner, including the air conditioner indoor unit described above. By arranging the evaporator 4, the water receiving tray 5 and the air duct component 1 in sequence from top to bottom along the vertical direction (according to the positive to negative direction of Z in the attached figure), the air conditioner can realize air outlet from the bottom, left and right, which can meet the customer's needs for multi-directional air supply and wide-area air outlet.

[0066] Other advantages of the air conditioner described in the present invention over the prior art are the same as the advantages of the air conditioner indoor unit over the prior art, which will not be repeated here.

[0067] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
