Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and more specifically, to an indoor air conditioner and a kitchen air conditioner. Background Art

[0002] When a duct machine is in use, it is usually installed inside a ceiling. This makes the design and manufacture of the duct machine have relatively high requirements for its thickness dimension in the up and down direction, that is: it is necessary to design the duct machine as thin as possible, while the requirements for its length dimension in the left and right direction and width dimension in the front and back direction are relatively low.

[0003] If the duct machine is directly used as a kitchen air conditioner, since the kitchen space is usually about 4 square meters, and when installing the duct machine, pipes need to be routed and space needs to be made for the flue in the ceiling space, the originally narrow space becomes extremely limited, making it difficult to meet the usage requirements in the kitchen space. Summary of the Utility Model

[0004] The first object of the utility model is to provide an indoor air conditioner to solve the technical problem that the solution of directly using a duct machine as a kitchen air conditioner is difficult to meet the usage requirements in the kitchen space.

[0005] The indoor air conditioner provided by the utility model includes a body, an air outlet panel, an exhaust duct, and a main control box for controlling the operating state of the indoor air conditioner. The body is placed above the ceiling, and the body is provided with an air inlet and an air outlet; the air outlet panel is installed on the ceiling, the air outlet panel is provided with an exhaust port, and the exhaust duct connects the air outlet and the exhaust port; the main control box is installed on the air outlet panel, and the main control box is located above the ceiling.

[0006] By providing an indoor air conditioner mainly composed of a body, an air outlet panel, an exhaust duct, and a main control box, where the main control box is used to control the operating state of the indoor air conditioner. When the indoor air conditioner is operating, external air flows into the body through the air inlet, and after being converted into the air conditioner air required by the indoor space, it is discharged from the air outlet to the exhaust duct, and further discharged into the indoor space through the exhaust port provided on the air outlet panel, realizing the cooling or heating of the indoor space.

[0007] By arranging the main control box on the air outlet panel instead of inside the body, it is possible to reduce the space occupied by the body, which is beneficial to reducing the size of the body, so that the relatively large-sized body in the indoor air conditioner can be installed in a narrow kitchen space, meeting the usage requirements of the indoor air conditioner in the kitchen space; and it also avoids the blockage of the air inlet and outlet of the body by the main control box. Moreover, this arrangement makes the main control box in the open space above the ceiling, which is also beneficial to the heat dissipation of the main control box and ensures the control performance of the main control box.

[0008] Further, the main control box includes an installation cavity and electrical components. A part of the air outlet panel is recessed upward above the ceiling to form the installation cavity, and the electrical components are accommodated in the installation cavity. Through the above arrangement, the installation cavity of the main control box is directly formed by the air outlet panel, that is to say, the installation cavity of the main control box and the air outlet panel are an integrated structure. This arrangement can not only reduce the number of parts and improve the assembly efficiency of the main control box, but also prevent the main control box from shifting relative to the air outlet panel. In addition, this arrangement can also form a maintenance opening at the opening of the installation cavity, so that when maintenance of the main control box is required, it can be directly carried out through the maintenance opening without disassembling the machine body, which is convenient to operate and improves the efficiency of maintenance work.

[0009] Further, the main control box further includes a box cover. The box cover is movably installed on the air outlet panel, and the box cover has a closed position for closing the installation cavity and an open position for exposing the electrical components. This arrangement can protect the electrical components during the operation of the air conditioner indoor unit, and when maintenance of the main control box is required, the electrical components can be exposed from the opening of the installation cavity to facilitate the operation of the operators.

[0010] Further, the box cover is rotatably connected to the air outlet panel; a fixing structure is further provided between the box cover and the air outlet panel, and the fixing structure is used for detachably fixedly connecting the box cover and the air outlet panel at the closed position. This arrangement realizes the fixed connection between the box cover and the air outlet panel at the closed position, so that the box cover can stably remain in the closed position and will not accidentally open during the operation of the air conditioner indoor unit.

[0011] Further, the box cover has a first end and a second end facing away from each other, and the first end is rotatably connected to the air outlet panel;

[0012] The fixing structure includes a clamping block and a clamping groove that are in clamping cooperation. One of the clamping block and the clamping groove is arranged at the second end, and the other of the clamping block and the clamping groove is arranged on the air outlet panel. This form of setting of the fixing structure can realize the quick connection between the box cover and the air outlet panel, and the connection efficiency is relatively high; and / or, the fixing structure includes a threaded post, a connection through hole and a connection screw. The connection through hole is opened at the second end, the threaded post is fixedly arranged in the installation cavity and is opposite to the connection through hole, and the connection screw passes through the connection through hole and is screwed onto the threaded post. This form of setting of the fixing structure is simple in structure, reliable in connection and low in cost. Moreover, the threaded post can also play a supporting role for the box cover to reduce the deformation of the box cover.

[0013] Further, a handle structure is further provided on a surface of the box cover facing away from the installation cavity. The handle structure includes a groove and a handle connected to the air outlet panel, and the handle is located in the groove. The provision of the above handle structure provides a force application point for the operator on the surface of the box cover. Among them, the provision of the groove provides an avoidance function for the operator's hand during the process of pulling the handle; and / or, a limiting structure is further provided between the box cover and the air outlet panel, and the limiting structure is used to keep the box cover in the open position. The provision of the above limiting structure enables the box cover to be limited after it is rotated and opened in place, so that the box cover can be kept in the open position, avoiding the free swing of the box cover caused by air flow disturbance and hitting the air outlet panel, which not only plays a certain protective role for the box cover and the air outlet panel, but also facilitates the operator to perform maintenance operations on the electrical components in the installation cavity.

[0014] Further, the number of the air supply openings is multiple, and the air conditioner indoor unit further includes air outlet covers, and the number of the air outlet covers is the same as the number of the air supply openings. Each air outlet cover is fixedly connected to the air outlet panel respectively; the air outlet cover includes an exhaust air cover, and an exhaust air pipe is connected between each exhaust air cover and the corresponding air supply opening. Among them, there is a clearance space with a distance not less than the width of the keel between any two adjacent air outlet covers. The provision of the above air outlet covers enables the exhaust air pipes connected to the air supply openings to be connected to the exhaust air covers, and the exhaust air covers play a transitional role in connecting the exhaust air pipes and the air outlet panel, reducing the air leakage at the connection between the exhaust air pipes and the air outlet panel, so that the air conditioner air can smoothly blow into the room through the exhaust air openings formed in the air outlet panel.

[0015] Further, the main control box is horizontally placed on the air outlet panel. By horizontally placing the main control box on the air outlet panel, not only can the occupation of the space above the ceiling by the main control box be reduced, but also when the box cover is in the open position, the exposed area of the main control box is relatively large, thus facilitating the maintenance operation of the main control box; and / or, a flame retardant coating is applied on the surface of the main control box. This setting enables the main control box to have a certain flame retardant effect and reduces the potential safety hazards during the use of the main control box; and / or, the main control box is connected to the power element of the machine body through a cable. This setting realizes the data transmission between the main control box and the power element in the machine body and ensures the control reliability of the main control box.

[0016] Further, the machine body includes a housing, and the housing includes a first column and a second column which are opposite and spaced apart from each other, and an air inlet is formed between the first column and the second column. This form of forming the air inlet by the interval between the two columns enables the air flow to enter through the air inlet with almost no blockage, increasing the air inlet area of the air inlet and ensuring the air intake volume. At the same time, the air volume loss is also reduced.

[0017] Further, the body further includes a water receiving tray which forms the bottom wall of the housing, and the heat exchanger of the body is installed on the water receiving tray. By integrating the water receiving tray with the bottom wall of the housing, that is to say, the water receiving tray not only has the function of receiving water, but also plays a role in closing the inner cavity of the housing below, reducing the number of components of the body of the air conditioner indoor unit and improving the assembly efficiency.

[0018] Further, a water absorption layer is fixedly arranged on the side of the water receiving tray facing away from the heat exchanger. By arranging the water absorption layer on the back of the water receiving tray, it is possible to absorb the condensed water attached to the back of the water receiving tray, avoiding damage to the ceiling caused by the condensed water dripping from the back of the water receiving tray into the ceiling space; and / or, reinforcing ribs are arranged on the side of the water receiving tray facing away from the heat exchanger. This setting can enhance the structural strength of the water receiving tray, increase the anti-deformation ability of the water receiving tray, extend the service life of the water receiving tray, and avoid deformation of the water receiving tray when the water volume is large, ensuring the water storage effect; and / or, the heat exchanger is a U-shaped heat exchanger, the opening of the U-shaped heat exchanger faces the air supply outlet, and drain openings are arranged on both sides of the heat exchanger on the water receiving tray. By arranging drain openings on both sides of the water receiving tray, when installing the body, one of the drain openings can be selectively retained according to the installation requirements, and the other drain opening can be blocked by a plug. This setting can meet different installation requirements of users.

[0019] The second object of the present invention is to provide a kitchen air conditioner to solve the technical problem that the solution of directly using a duct machine as a kitchen air conditioner is difficult to meet the use requirements in the kitchen space.

[0020] The kitchen air conditioner provided by the present invention includes a return air panel and the above-mentioned air conditioner indoor unit, the return air panel is arranged on the ceiling, and the return air panel is spaced from the air outlet panel of the air conditioner indoor unit.

[0021] By arranging the above-mentioned air conditioner indoor unit in the kitchen air conditioner, correspondingly, the kitchen air conditioner has all the advantages of the above-mentioned air conditioner indoor unit, which will not be elaborated one by one here. Description of the Drawings

[0051] At present, the interior of an air duct machine is divided into a heat exchanger chamber and a blower chamber. To increase the heat exchange area, the heat exchanger is usually placed obliquely in the heat exchanger chamber, which results in a relatively large width of the air duct machine and occupies a large amount of space in the ceiling along the front-back direction. Moreover, the existing air duct machines mainly use the side air outlet method. To increase the air volume, the air outlet is usually made thinner and longer, which also leads to a relatively large length of the air duct machine and occupies a large amount of space in the ceiling along the left-right direction.

[0052] Therefore, if the structure of the existing air duct machine is directly transferred to a kitchen air conditioner, it is obviously too large in size and cannot meet the usage requirements of a narrow kitchen space, leaving a large room for improvement.

[0053] Based on this, the purpose of the present utility model is to provide an air conditioner indoor unit and a kitchen air conditioner to solve the technical problem that it is difficult to meet the usage requirements in a kitchen space when directly using an air duct machine as a kitchen air conditioner.

[0054] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0055] Figure 1 One of the schematic structural diagrams of the kitchen air conditioner provided in this embodiment installed on the ceiling 020; Figure 2 The top view of the structure of the kitchen air conditioner provided in this embodiment installed on the ceiling 020; Figure 3 The bottom view of the structure of the kitchen air conditioner provided in this embodiment installed on the ceiling 020; Figure 4 For Figure 3 The A-A cross-sectional view in Figure 5 Another schematic structural diagram of the kitchen air conditioner provided in this embodiment installed on the ceiling 020. As Figures 1 to 5 shown, this embodiment provides a kitchen air conditioner, including a return air panel 030 and an air conditioner indoor unit 010. Among them, the return air panel 030 is arranged on the ceiling 020, and the return air panel 030 is spaced apart from the air outlet panel 200 of the air conditioner indoor unit 010.

[0056] When this kitchen air conditioner is in use, the air-conditioning air generated by the air conditioner indoor unit 010 is blown from the air outlet panel 200 into the indoor space. At the same time, the air flow in the indoor space flows back to the air conditioner indoor unit 010 through the return air opening, forming an air flow cycle to achieve the purpose of cooling or heating the kitchen space.

[0057] In the following text, the specific structure and working principle of the air conditioner indoor unit 010 will be elaborated in detail.

[0058] Please continue to refer to Figure 4, the air conditioner indoor unit 010 provided in this embodiment includes a body 100, an air outlet panel 200, an exhaust duct 300, and a main control box 400 for controlling the operating state of the air conditioner indoor unit 010. Among them, the body 100 is placed above the ceiling 020, and the body 100 is provided with an air intake opening 111 and an air supply opening 112; the air outlet panel 200 is installed on the ceiling 020.

[0059] Figure 6 is a partial structural decomposition schematic diagram of the air conditioner indoor unit 010 provided in this embodiment; Figure 7 is one of the structural schematic diagrams of the air conditioner indoor unit 010 provided in this embodiment at the air outlet panel 200 (the box cover 430 is in the closed position); Figure 8 is the second structural schematic diagram of the air conditioner indoor unit 010 provided in this embodiment at the air outlet panel 200 (the box cover 430 is not shown). Please continue to refer to Figure 4 , and in combination with Figures 6 to 8 , the air outlet panel 200 is provided with an air exhaust opening 210, and the exhaust duct 300 connects the air supply opening 112 and the air exhaust opening 210; the main control box 400 is installed on the air outlet panel 200, and the main control box 400 is located above the ceiling 020.

[0060] When the air conditioner indoor unit 010 is operating, external air flow enters the body 100 from the air intake opening 111. After being converted into the air conditioner air required by the indoor space, it is discharged from the air supply opening 112 to the exhaust duct 300, and further discharged to the indoor space through the air exhaust opening 210 provided on the air outlet panel 200, realizing the cooling or heating of the indoor space.

[0061] By setting the main control box 400 on the air outlet panel 200 instead of inside the body 100, the space occupied by the body 100 can be reduced, which is beneficial to reducing the size of the body 100. Thus, the relatively large-sized body 100 in the air conditioner indoor unit 010 can be installed in a narrow kitchen space, meeting the use requirements of the air conditioner indoor unit 010 in the kitchen space; it also avoids the blockage of the air intake and exhaust of the body 100 by the main control box 400. Moreover, this setting makes the main control box 400 in the open space above the ceiling 020, which is also beneficial to the heat dissipation of the main control box 400 and ensures the control performance of the main control box 400.

[0062] Please continue to refer to Figures 6 to 8 , in this embodiment, a guiding air door 230 is movably arranged at the air exhaust opening 210. Among them, in the shutdown state of the air conditioner indoor unit 010, the guiding air door 230 can be moved to a position where it blocks the air exhaust opening 210, avoiding the exposure of the internal structure of the ceiling 020; when the air conditioner indoor unit 010 needs to supply air to the room, the guiding air door 230 opens, exposing the air exhaust opening 210, so that the air conditioner air can be sent into the room through the air exhaust opening 210 to achieve the corresponding cooling or heating purpose.

[0063] Please continue to refer to Figure 6 and Figure 8 In this embodiment, the main control box 400 includes an installation cavity 410 and an electrical component 420. Specifically, a part of the air outlet panel 200 is recessed upward above the suspended ceiling 020 to form the installation cavity 410, and the electrical component 420 is accommodated in the installation cavity 410.

[0064] Through the above settings, the installation cavity 410 of the main control box 400 is directly formed by the air outlet panel 200. That is to say, the installation cavity 410 of the main control box and the air outlet panel 200 are of an integrated structure. This setting can not only reduce the number of parts and improve the assembly efficiency of the main control box 400, but also prevent the main control box 400 from shifting relative to the air outlet panel 200. In addition, this setting can also form a maintenance opening 220 at the opening of the installation cavity 410, so that when the main control box 400 needs to be maintained, it can be directly carried out through the maintenance opening 220 without disassembling the body 100, which is convenient to operate and improves the maintenance operation efficiency.

[0065] Please continue to refer to Figure 6 In this embodiment, the electrical component 420 may include a display module 421 and a PCB (Printed Circuit Board) 422.

[0066] Figure 9 FIG. 3 is a schematic diagram of the structure of the air conditioner indoor unit 010 at the air outlet panel 200 in this embodiment (the box cover 430 is in the open position). Please continue to refer to Figure 6 and Figure 7 and in combination with Figure 9 In this embodiment, the main control box 400 may further include a box cover 430. Specifically, the box cover 430 is movably installed on the air outlet panel 200, and the box cover 430 has a closed position for closing the installation cavity 410 and an open position for exposing the electrical component 420.

[0067] When the air conditioner indoor unit 010 is operating normally, the box cover 430 is in the closed position. At this time, the installation cavity 410 is closed by the box cover 430, and the electrical component 420 located in the installation cavity 410 will not be exposed through the opening of the installation cavity 410. This setting can protect the electrical component 420 and prevent foreign impurities from entering the installation cavity 410 and damaging the electrical component 420. When the main control box 400 needs to be repaired, the box cover 430 can be placed in the open position. At this time, the electrical component 420 is exposed from the opening of the installation cavity 410, which is convenient for the operator to perform repair operations.

[0068] Please continue to refer to Figure 6, in this embodiment, the main control box 400 is horizontally placed on the air outlet panel 200. Among them, the main control box 400 is generally a flat and wide rectangular parallelepiped structure. "The main control box 400 is horizontally placed on the air outlet panel 200" means that the thickness direction of the main control box 400 is along the up and down direction, and the longer edge of the main control box 400 is parallel to the horizontal plane.

[0069] By horizontally placing the main control box 400 on the air outlet panel 200, not only can the occupation of the space above the ceiling 020 by the main control box 400 be reduced, but also when the box cover 430 is in the open position, the exposed area of the main control box 400 is relatively large, facilitating the maintenance operation of the main control box 400.

[0070] It should be noted that in other embodiments, the main control box 400 can also be set to be vertically placed on the air outlet panel 200. At this time, the longer edge of the main control box 400 is perpendicular to the horizontal plane.

[0071] Figure 10 For Figure 9 the partial structural schematic diagram at position B. Please continue to refer to Figure 9 , and in combination with Figure 10 , in this embodiment, the box cover 430 is rotatably connected to the air outlet panel 200; a limiting structure 600 is further provided between the box cover 430 and the air outlet panel 200, and among them, the limiting structure 600 is used to keep the box cover 430 in the open position.

[0072] The setting of the above-mentioned limiting structure 600 enables the box cover 430 to be limited after it is rotated and opened in place, so that the box cover 430 is kept in the open position, avoiding the box cover 430 from freely swinging and hitting the air outlet panel 200 due to air flow disturbance. This not only plays a certain protective role for the box cover 430 and the air outlet panel 200, but also facilitates the maintenance operation of the electrical components 420 in the installation cavity 410 by the operators.

[0073] Please continue to refer to Figure 10 , in this embodiment, the limiting structure 600 may include an arc-shaped groove opened on the air outlet panel 200 and a limiting post provided on the box cover 430. Among them, the end of the arc-shaped groove is set to be closed. When the box cover 430 switches between the closed position and the open position, the limiting post slides in the arc-shaped groove; as the box cover 430 is opened in place, the limiting post will be stuck in the closed end of the arc-shaped groove to achieve fixation. When it is necessary to switch the box cover 430 from the open position to the closed position, under the action of an external force, the limiting post will withdraw from the closed end so that the box cover 430 can freely rotate towards the closed position.

[0074] It should be noted that in other embodiments, the lid 430 can also be arranged to be slidably connected to the air outlet panel 200. At this time, the sliding of the lid 430 on the air outlet panel 200 can be used to realize the switching of the lid 430 between the open position and the closed position.

[0075] Figure 11 Fig. 4 is a bottom view of the structure of the air conditioner indoor unit 010 provided in this embodiment at the air outlet panel 200. As Figure 11 shown, a fixing structure 500 can also be arranged between the lid 430 and the air outlet panel 200. Among them, the fixing structure 500 is used to detachably and fixedly connect the lid 430 and the air outlet panel 200 at the closed position.

[0076] The arrangement of the above-mentioned fixing structure 500 realizes the fixed connection between the lid 430 and the air outlet panel 200 at the closed position, so that the lid 430 can stably stay at the closed position without accidentally opening during the operation of the air conditioner indoor unit 010.

[0077] Figure 12 Fig. Figure 11 is a C-C cross-sectional view of Figure 13 Fig. Figure 12 and Fig. Figure 12 and Figure 13 shown, in this embodiment, the lid 430 has a first end and a second end facing away from each other. Among them, the first end is rotatably connected to the air outlet panel 200; the fixing structure 500 can include a threaded post 530, a connecting through hole 540 and a connecting screw (not shown in the figure). The connecting through hole 540 is opened at the second end, the threaded post 530 is fixedly arranged in the installation cavity 410 and is opposite to the above-mentioned connecting through hole 540, and the connecting screw passes through the connecting through hole 540 and is screwed onto the threaded post 530.

[0078] When it is necessary to fix the lid 430 at the closed position, the connecting screw can pass through the connecting through hole 540 from bottom to top and be screwed onto the threaded post 530. By using the fastening effect of the connecting screw, the fixed connection between the lid 430 and the air outlet panel 200 is realized. This setting form of the fixing structure 500 has a simple structure, reliable connection and low cost. Moreover, the threaded post 530 can also play a supporting role for the lid 430 to reduce the deformation of the lid 430.

[0079] Figure 14 Fig. Figure 11 is an E-E cross-sectional view of Figure 15 Fig. Figure 14 and Fig. Figure 14 and Figure 15 shown, the fixing structure 500 can also include a clamping block 510 and a clamping groove 520 that are clamped and matched. Among them, the clamping block 510 is arranged at the second end, and the clamping groove 520 is arranged on the air outlet panel 200.

[0080] When the lid 430 is switched from the open position to the closed position, as the lid 430 continues to rotate, the latch 510 provided on the lid 430 will be inserted into the card slot 520 opened on the air outlet panel 200. By using the clamping cooperation between the latch 510 and the card slot 520, the clamping and fixing of the second end of the lid 430 and the air outlet panel 200 are realized. This setting form of the fixing structure 500 can not only realize the connection and fixing of the lid 430 and the air outlet panel 200, but also realize the positioning of the lid 430 on the air outlet panel 200, so as to facilitate the fastening and assembly of the connecting screws.

[0081] It can be understood that in other embodiments, the latch 510 can also be provided on the air outlet panel 200, and the card slot 520 can be opened on the lid 430. It can also use the clamping cooperation between the latch 510 and the card slot 520 to realize the clamping and fixing of the lid 430 and the air outlet panel 200.

[0082] Please continue to refer to Figure 15 , in this embodiment, a handle structure 440 is further provided on the side of the lid 430 facing away from the installation cavity 410. Specifically, the handle structure 440 includes a groove 441 and a handle 442 connected to the air outlet panel 200. The handle 442 is located in the groove 441.

[0083] When it is necessary to switch the lid 430 from the closed position to the open position, the fastening connection of the lid 430 by the connecting screw can be released first, and then, by pulling the handle 442, a rotational force is applied to the lid 430, so that the latch 510 can be withdrawn from the card slot 520, thereby realizing the rotational opening of the lid 430.

[0084] The above setting of the handle structure 440 provides a force application point for the operator on the surface of the lid 430. Among them, the setting of the groove 441 provides an avoidance function for the operator's hand during the process of pulling the handle 442.

[0085] Please continue to refer to Figure 6 and Figure 12 , in this embodiment, the number of air supply ports 112 is two. The air conditioner indoor unit 010 may further include air outlet covers 700. The number of air outlet covers 700 is the same as the number of air supply ports 112, which is also two. Each air outlet cover 700 is fixedly connected to the air outlet panel 200 respectively; the air outlet cover 700 includes an exhaust hood 710. A exhaust duct 300 is connected between each exhaust hood 710 and the corresponding air supply port 112. Among them, there is a clearance space 720 with a distance not less than the width of the keel between the two air outlet covers 700.

[0086] The arrangement of the above-mentioned air outlet cover 700 enables the exhaust pipe 300 connected to the air supply port 112 to be connected to the exhaust cover 710, and the exhaust cover 710 plays a transitional role in the connection between the exhaust pipe 300 and the air outlet panel 200, thereby reducing the air flow leakage at the connection between the exhaust pipe 300 and the air outlet panel 200, so that the air conditioning air can be smoothly blown into the room through the exhaust port 210 opened in the air outlet panel 200. This arrangement obtains the avoidance space 720 without slotting the air outlet cover 700, thereby reducing the manufacturing cost.

[0087] In this embodiment, in order to avoid air leakage between the avoidance space 720 and the exhaust port 210, a wind shield (not shown in the figure) can also be set, so that the air delivered by the exhaust cover 710 can be smoothly delivered from the exhaust port 210 of the air outlet panel 200, and will not leak into the ceiling space from the gap between the avoidance space 720 and the keel.

[0088] It should be noted that, in other embodiments, the number of exhaust hoods 710 can be changed according to the number of air supply outlets 112. For example, when the number of air supply outlets 112 is three, the number of exhaust hoods 710 is also three. The three exhaust hoods 710 are all connected to the corresponding air supply outlets 112 through independent exhaust ducts 300. At this time, there is an avoidance space 720 between any two adjacent air outlet hoods 700, the distance of which is not less than the width of the keel.

[0089] In this embodiment, the surface of the main control box 400 is coated with a flame retardant coating, which enables the main control box 400 to have a certain flame retardant effect and reduces the potential safety hazards of the main control box 400 during use.

[0090] Wherein, a flame retardant coating may be provided on both the outer surface and the inner surface of the main control box 400 .

[0091] Please continue to refer to Figure 4 In this embodiment, the main control box 400 is connected to the power element of the body 100 through the cable 450. This configuration realizes data transmission between the main control box 400 and the power element in the body 100, and ensures the control reliability of the main control box 400.

[0092] Figure 16 A schematic structural diagram of a body 100 of an air-conditioning indoor unit 010 provided in this embodiment; Figure 17 FIG. 1 is a schematic diagram of a partial structural decomposition of the body 100 of the air conditioner indoor unit 010 provided in this embodiment. Figure 16 and Figure 17 As shown, the body 100 may include a housing 110 , wherein the housing 110 includes a first column 113 and a second column 114 that are oppositely and spaced apart, and an air inlet 111 is formed between the first column 113 and the second column 114 .

[0093] This form of forming the air intake port 111 by using the gap between the two upright columns allows the air to enter through the air intake port 111 with almost no obstruction, increasing the air intake area of the air intake port 111, ensuring the air intake volume, and at the same time, reducing the air volume loss.

[0094] Please continue to refer to Figure 16 and Figure 17 In this embodiment, the housing 110 is generally in the shape of a cuboid, including a top wall and a bottom wall that are opposite and spaced apart in the up and down direction, and a left side, a right side, a front side, and a rear side provided between the top wall and the bottom wall. Among them, the first upright column 113 and the second upright column 114 are provided on the rear side of the housing 110. That is to say, the air intake port 111 is located on the rear side of the housing 110; the air outlet 112 is located on the front side of the housing 110.

[0095] In this embodiment, the heat exchanger 130 of the body 100 is a U-shaped heat exchanger. Among them, the opening of the U-shaped heat exchanger faces the air outlet 112. That is to say, the opening of the heat exchanger 130 faces the front side of the housing 110, and the three-section structure of the heat exchanger 130 faces the left side, the rear side, and the right side of the housing 110 respectively. By setting the heat exchanger 130 as a U-shaped heat exchanger, the heat exchange amount of the heat exchanger 130 can be increased, the heat exchange efficiency can be improved, and thus the performance of the air conditioner indoor unit 010 in this embodiment can be enhanced.

[0096] In this embodiment, the housing 110 may further include side air vents 115. Among them, side air vents 115 are provided on both the left side and the right side of the housing 110, and the side air vents 115 are also formed by the space between two upright columns that are spaced apart from each other. This setting enables the air conditioner indoor unit 010 to form three-sided air intake during operation, and the lateral air intake volume is also relatively large.

[0097] It should be noted that in this embodiment, the "left and right direction" can be represented by Figure 16 and Figure 17 the arrow ab in Figure 16 and Figure 17 the arrow cd in Figure 16 and Figure 17 the arrow ef in

[0098] In this embodiment, the dimension of the housing 110 in the left and right direction is less than 600 mm, the dimension of the housing 110 in the front and rear direction is less than 250 mm, and the dimension of the housing 110 in the up and down direction is less than 230 mm. For Figure 16 illustration, that is to say, L < 600 mm, B < 250 mm, H < 230 mm.

[0099] By setting the outer shell 110 within the above-mentioned size range, after removing the aluminum gusset plate, the body 100 of the air conditioner indoor unit 010 can be directly inserted into the internal space of the suspended ceiling 020 from bottom to top, realizing the installation without damaging the suspended ceiling 020 or cutting the keel after the kitchen suspended ceiling 020 has been decorated.

[0100] Figure 18 It is a top view of the structure of the water receiving tray 120 of the air conditioner indoor unit 010 provided in this embodiment; Figure 19 It is a sectional view of the structure of the water receiving tray 120 of the air conditioner indoor unit 010 provided in this embodiment; Figure 20 It is a bottom view of the structure in which the heat exchanger 130 of the air conditioner indoor unit 010 provided in this embodiment is installed on the water receiving tray 120. Please continue to refer to Figure 17 and in combination with Figures 18 to 20 In this embodiment, the body 100 may further include a water receiving tray 120, wherein the water receiving tray 120 forms the bottom wall of the outer shell 110, and the heat exchanger 130 is installed on the water receiving tray 120.

[0101] The setting of the water receiving tray 120 can realize the centralized collection of the condensed water generated during the operation of the heat exchanger 130, avoiding the condensed water from dripping onto the suspended ceiling 020 and causing damage to the suspended ceiling 020. By setting the water receiving tray 120 and the bottom wall of the outer shell 110 as an integral structure, that is to say, the water receiving tray 120 not only has the function of receiving water, but also plays the role of closing the inner cavity of the outer shell 110 below, reducing the number of parts of the body 100 of the air conditioner indoor unit 010 and improving the assembly efficiency.

[0102] Please continue to refer to Figure 17 In this embodiment, a water absorption layer 121 is fixedly arranged on the side of the water receiving tray 120 facing away from the heat exchanger 130. That is to say, the water absorption layer 121 is fixedly arranged on the back of the water receiving tray 120.

[0103] By arranging the water absorption layer 121 on the back of the water receiving tray 120, it can realize the absorption of the condensed dew adhering to the back of the water receiving tray 120, avoiding damage to the suspended ceiling 020 space caused by the condensed dew dripping from the back of the water receiving tray 120 onto the suspended ceiling 020.

[0104] Specifically, the material of the water absorption layer 121 can be sponge.

[0105] Please continue to refer to Figure 17 In this embodiment, a reinforcing rib 122 is arranged on the side of the water receiving tray 120 facing away from the heat exchanger 130.

[0106] The arrangement of the reinforcing rib 122 can enhance the structural strength of the water receiving tray 120, increase the anti-deformation ability of the water receiving tray 120, extend the service life of the water receiving tray 120, and avoid deformation of the water receiving tray 120 when the water volume is large, thus ensuring the water storage effect.

[0107] Please continue to refer to Figure 18 and Figure 20 , in this embodiment, the water receiving tray 120 is provided with drain openings 123 on both sides of the heat exchanger 130.

[0108] By providing drain openings 123 on both sides of the water receiving tray 120, when installing the body 100, one of the drain openings 123 can be selectively retained according to the installation requirements, and the other drain opening 123 can be blocked by a plug 124. This arrangement can meet different installation requirements of users.

[0109] Please continue to refer to Figure 8 , in this embodiment, the water receiving tray 120 is provided with a sunken structure 125, wherein the water inlet of the water pump 140 of the body 100 is communicated with the sunken structure 125.

[0110] The arrangement of the sunken structure 125 can precipitate impurities in the condensed water, prevent the impurities from being sucked into the water pump 140 and blocking or even damaging the water pump 140, thus playing a certain protective role for the water pump 140.

[0111] In this embodiment, the wind wheel assembly 150 of the body 100 can be located in the internal space of the heat exchanger 130, so that the three-section structure of the heat exchanger 130 surrounds the wind wheel assembly 150.

[0112] This arrangement not only effectively utilizes the internal space of the housing 110, ensures the compactness of the structure of the air conditioner indoor unit 010, is beneficial to reducing the size of the body 100, but also enables the external air flow path during the operation of the air conditioner indoor unit 010 to be that the external air first passes through the heat exchanger 130, then passes through the wind wheel assembly 150, and is further discharged through the air outlet 112, which is a suction air flow process. Compared with the blowing air flow process of a conventional duct machine, the heat exchange effect is improved.
