Description

Technical Field

[0001] This invention relates to the field of air conditioning equipment technology, and in particular to a novel ceiling-mounted indoor unit frame structure and air conditioner. Background Technology

[0002] like Figures 1-2 As shown, during the overall assembly of the commercial air conditioning ceiling unit, the chassis 1 is fixed and supported by a panel device 2 formed by multiple panels (e.g., panel A2a, panel B2b). This supports and builds the ceiling unit frame, followed by the assembly of the drip tray 6, chassis foam 4, and other structural and system components to complete the internal enclosure and insulation space. The multiple panels are fixed along the edge of the chassis using common screws to form the outer and bottom structures. Simultaneously, the drip tray 6 is fixed to the panel device 2 around its perimeter with screws, forming an embedded assembly.

[0003] The following shortcomings exist in the actual manufacturing and assembly process:

[0004] 1. Strength Risk: Due to the large area of ​​the perimeter panels, and considering material costs, the thickness is generally relatively small. Therefore, relying on the thickness of the perimeter panels for vertical support results in poor strength.

[0005] 1) The panel is integrally formed, resulting in large sheet metal deformation, which makes it easy for parts to deform and gaps to form during assembly;

[0006] 2) The upper and lower parts are only connected by the enclosure device 2 without strong support points, which can easily lead to overall deformation and denting during actual transportation, falling, and trampling.

[0007] 3) During hoisting, the hook assembly 3 is subjected to a large force, and its close proximity to the fixed support of the enclosure can easily cause the enclosure to deform under stress;

[0008] 4) When the indoor unit is running, the motor vibration is transmitted through the chassis 1 to the overall enclosure device 2, which can easily generate resonance noise.

[0009] 2. Maintenance difficulty: The large number of parts and components involved in the disassembly process during internal maintenance and repair due to the surrounding frame panels.

[0010] 1) When inspecting and cleaning the evaporator 8 in case of internal malfunction of the ceiling unit, it is necessary to disassemble the panel, guide ring, electrical control box, and even the water tray 6.

[0011] 2) The ceiling-mounted unit cannot be disassembled and inspected from the side;

[0012] 3) If the chassis foam 4 is damaged and needs to be replaced, almost all fixed structural parts need to be removed.

[0013] 3. Poor manufacturability: The overall panel processing and transportation are difficult (sheet metal deformation), and the assembly process is prone to deformation. The overall material storage space and transfer of the chassis foam are also difficult.

[0014] 4. Layout: The ceiling machine periphery is supported by the whole surrounding board, and the layout is limited. The strength of the surrounding board cannot independently meet the hanging and lifting support function, and the hook assembly 3 for lifting function is still needed. The bottom disc foam 4 needs to be cooperated with the whole structure to install the water pump and play an auxiliary supporting role. The drainage pump device 5 fixed structure is installed on the bottom disc foam 4, and the installation and disassembly are difficult. SUMMARY

[0058] Embodiment 1

[0059] As shown in Figures 3-12 The present application discloses a new type of ceiling indoor unit frame structure, comprising a chassis 1, a water collecting tray 6 and a support column assembly 7, the support column assembly 7 is provided with multiple, the upper and lower ends of the multiple support column assemblies 7 are respectively detachably connected with the water collecting tray 6 and the chassis 1.

[0060] The new type of ceiling indoor unit frame structure disclosed in the present application, by setting the support column assembly 7, combined with the chassis 1 and the water collecting tray 6 to build a strong support column frame structure, thereby completing the fixation and assembly of the overall structure, improving the overall strength of the ceiling indoor unit frame structure. At the same time, when the ceiling indoor unit is running, the chassis is subjected to stress vibration, and the support column assembly 7 is used to connect the water collecting tray 6 and the chassis 1. When the motor vibration and the chassis are transmitted, the transmission structure of the chassis vibration is changed. At the same time, due to the change of the weight of the object transmitted to the support column assembly 7, the vibration frequency can be effectively changed, and the fixed frequency resonance deformation phenomenon is improved.

[0061] The new type of ceiling indoor unit frame structure described in the present application enhances the overall strength of the ceiling indoor unit frame structure, improves the vibration transmission characteristics, improves the stability and reliability of the ceiling indoor unit, improves the fixed frequency resonance deformation phenomenon, and reduces the problems caused by vibration.

[0062] As a preferred example of the present application, the support column assembly 7 comprises a support body 71, a first connecting plate 76 is arranged at the upper end of the support body 71, and the first connecting plate 76 is detachably connected with the water pan hook 61 on the water pan 6 through a first fixing screw 77, and the lower end of the support body 71 is detachably connected with the bottom plate 1 through a second fixing screw 78. The novel ceiling machine frame structure disclosed in the present application is characterized in that the water pan 6 is attached to the support body 71 of the support column assembly 7 from top to bottom, the water pan hook 61 is supported on the first connecting plate 76 at the upper end of the support body 71 and is fastened through the first fixing screw 77, the lower end of the support body 71 is attached to the bottom plate 1, and is fastened through the second fixing screw 78, as shown in Figure 7 , thereby forming a built-up support and fixing frame.

[0063] As a preferred example of the present application, a hook connecting part 72 is arranged on the support body 71 near the middle part, and the hook connecting part 72 is detachably connected or welded with the support body 71. As shown in Figure 7 , a fourth connecting hole 74 is arranged on the support body 71, and the fourth connecting hole 74 is screw-connected or welded with the support body 71. As a preferred example, the hook connecting part 72 is spot-welded on the support body 71. The arrangement integrates the hoisting structure of the ceiling machine on the support column assembly 7, simplifies the structure design, ensures the reliability of the overall hoisting of the ceiling machine, and reduces the deformation problem of the surrounding plate.

[0064] As a preferred example of the present application, a surrounding plate device 2 is arranged between the bottom plate 1 and the water pan 6, and the surrounding plate device 2 is detachably connected with the support body 71. Specifically, the surrounding plate device 2 comprises a plurality of surrounding plates, a connecting bent plate 2h is formed at the position where each surrounding plate is connected with the support body 71, a first connecting hole 2e and a second connecting hole 2f are arranged on the connecting bent plate 2h, and correspondingly, a third connecting hole 73 and a fifth connecting hole 75 are formed at the upper and lower ends of the support body 71, and the third connecting hole 73 and the fifth connecting hole 75 are connected with the first connecting hole 2e and the second connecting hole 2f, respectively. As a preferred example, the third connecting hole 73 and the fifth connecting hole 75 are both arranged on the support body 71 between the first connecting plate 76 and the second fixing screw 78, and two third connecting holes 73 and two fifth connecting holes 75 are arranged on the support body 71, and the two third connecting holes 73 and the two fifth connecting holes 75 are screw-connected with the first connecting hole 2e and the second connecting hole 2f on the two surrounding plates, respectively. As an example of the present application, the connecting line of the two third connecting holes 73 is arranged in a horizontal manner, and the connecting line of the two fifth connecting holes 75 is also arranged in a horizontal manner.

[0065] The above arrangement simplifies the assembly structure of the ceiling machine frame, improves hoisting reliability, and reduces the deformation problem of the coaming, thereby improving the overall performance and stability of the ceiling machine frame structure.

[0066] As a preferred example of the present application, a first clearance portion 2c is provided on the connecting bent plate 2h for avoiding the connection of the second fixing screw 78 with the chassis 1. As an example of the present application, a second clearance portion 2d is provided on the connecting bent plate 2h for avoiding the connection position of the hook connecting portion 72 and the support body 71. Through the design of the above-mentioned clearance portion, the connection operation is avoided to be interfered by the connecting bent plate 2h on the coaming, and more operation space is provided, so that it is more convenient and efficient to install, remove or adjust the connecting parts, the operability of the connection is improved, and the overall assembly and maintenance efficiency is improved.

[0067] As a preferred example of the present application, the coaming device 2 described in the present application comprises four coamings, namely a first coaming assembly 21, a second coaming assembly 22, a third coaming assembly 23 and a fourth coaming assembly 24. Correspondingly, four support column assemblies 7 are provided for the sequential connection of the first coaming assembly 21, the second coaming assembly 22, the third coaming assembly 23 and the fourth coaming assembly 24, and the four support column assemblies 7 are arranged at the four corners of the inner machine frame structure.

[0068] The above arrangement further defines the structure of the coaming device 2 and the arrangement structure of the support column assembly 7 connecting the coaming device 2. By arranging one support column assembly 7 at each of the four corners of the inner machine frame structure, a four-corner strong support column structure is formed, which can prevent shaking and stress deformation during the operation vibration, transportation, falling, stepping and multi-layer stacking of the ceiling machine, and the overall structural strength is increased.

[0069] Through the above-mentioned four-corner frame support, the support column is stressed and supported during falling, and has high impact resistance and deformation resistance. The applicant compares and tests the falling phenomena of the new and old architectures of the inner machine, and the test results are as follows:

[0070]

[0071] In addition, during the operation of the ceiling inner machine, the chassis 1 is stressed and vibrated, and the frequency of object vibration is related to the structure, mass and center of gravity of the object. Due to the strong fixation of the four-corner support column, when the motor vibration is transmitted to the chassis, the transmission structure of the chassis vibration is changed, and at the same time, the weight of the object transmitted to the support column also changes, which can effectively change the vibration frequency.

[0072] According to Figure 13 As shown in the old architecture fixed frequency test and Figure 14 As shown in the new architecture fixed frequency test, inFigure 13 And Figure 14 In the figure, the X-axis is frequency Hz, and the Y-axis is the solid frequency vibration value. When the peak of the figure curve coincides with 50 Hz and the multiple frequency, it is the resonance point, which produces resonance. The old ceiling machine frame has multiple peak values at 50 Hz multiple frequency. The new ceiling machine frame peak value avoids 50 Hz multiple frequency, effectively avoiding 50 Hz multiple frequency, so that the resonance noise value is also improved.

[0073] The applicant also compares the noise tests of the new and old frame structures, and the test results are as follows:

[0074]

[0075] In the above figure, the Figure 15 ~ Appendix Figure 20 In the figure, the X-axis is noise frequency, and the Y-axis is noise value. When the noise frequency is abnormally large at a certain value, that is, the curve has an abnormal peak along the slope, it means that abnormal sound is produced at this frequency band, Figures 15-20 The cross at the intersection in the figure is the corresponding noise.

[0076] The strong pillar new ceiling machine frame structure designed by the application is shown in Figure 5 A support column assembly 7 is arranged at each of the four azimuth angles of the chassis 1. The four-azimuth support column is designed at the center of gravity G of the ceiling machine, and no fixed value is provided at this position. The fixed size is designed according to the gravity distribution.

[0077] As a preferred example of the present application, the first enclosure assembly 21 includes a first enclosure 211, a first foam 212, the second enclosure assembly 22 includes a second enclosure 221, a second foam 222, the third enclosure assembly 23 includes a third enclosure 231, a third foam 232, the fourth enclosure assembly 24 includes a fourth enclosure 241, a fourth foam 242, the first foam 212 is connected with the first enclosure 211, the second enclosure 221 is connected with the second foam 222, the third enclosure 231 is connected with the third foam 232, and the fourth enclosure 241 is connected with the fourth foam 242. The enclosure device 2 of the present application is provided with a foam assembly 10 inside the enclosure device 2, which includes a first foam 212, a second foam 222, a third foam 232, and a fourth foam 242. The first foam 212, the second foam 222, the third foam 232, and the fourth foam 242 form four-azimuth first enclosure assembly 21, second enclosure assembly 22, third enclosure assembly 23, and fourth enclosure assembly 24 with the first enclosure 211, the second enclosure 221, the third enclosure 231, and the fourth enclosure 241, respectively. The enclosure assembly formed by the enclosure and the foam assembly has the functions of sealing and heat preservation, can be separately removed, and is convenient for cleaning the evaporator 8 in the ceiling machine. Compared with the ceiling machine ring package structure in the prior art, when cleaning the evaporator 8, the faceplate, flow guide ring, and electric control box need to be disassembled, and water flow is sprayed from the inside for cleaning, which is complicated and easy to damage other parts. The new ceiling machine frame structure of the present application can be removed from the side after removing the enclosure and the heat preservation foam, and the water flow is sprayed from the outside for cleaning, which is simple and efficient, and is not easy to splash and damage other parts. The maintenance and cleaning directions are shown in the structure of Figure 10 Figure 10 The arrows in the structure

[0078] As a preferred example of the present application, the enclosure of the enclosure device 2 and the corresponding foam in the foam assembly 10 are pre-assembled by adhesion. That is, the first foam 212 and the first enclosure 211 are pre-assembled together by adhesion, the second enclosure 221 and the second foam 222 are pre-assembled together by adhesion, the third enclosure 231 and the third foam 232 are pre-assembled together by adhesion, and the fourth enclosure 241 and the fourth foam 242 are pre-assembled together by adhesion. The enclosure and the heat preservation foam of each enclosure assembly in the enclosure device 2 are assembled by adhesion, etc., and can be assembled as a whole at any time, and can be wrapped or exposed in the ceiling cavity.

[0079] ​As a preferred example of this application, a drain pump assembly 9 is provided on the enclosure device 2. The drain pump assembly 9 includes a drain pump 91 and a valve plate 92, and the valve plate 92 is detachably fixed to the first enclosure plate 211 of the first enclosure assembly 21. This arrangement allows the drain pump assembly in the ceiling machine to be independently installed on the side of the enclosure plate using a valve plate type. During after-sales maintenance, it is not necessary to disassemble the parts into the inner cavity; the drain pump assembly can be inspected and replaced from the side.

[0080] The key feature of the novel ceiling-mounted indoor unit frame structure described in this invention is the use of a frame structure to build the ceiling-mounted indoor unit frame. The structure is achieved by relying on the support column assembly 7 as the load-bearing column. On the basis of the outer frame structure, structural components such as the enclosure panel, water tray, and water pump assembly are fixed, thereby enhancing the support strength. The enclosure panel structure can be disassembled individually.

[0085] The air conditioner described in this application has the following advantages:

[0086] 1. Strength: The four-directional strong support columns can prevent shaking and deformation under stress during operation, vibration, transportation, drops, trampling, and multi-layer stacking, increasing the overall structural strength. When the indoor unit is running, the strong fixed structure can effectively reduce vibration transmission and minimize resonance noise.

[0087] 2. Easy to disassemble and clean: 1) The four surrounding panels can be disassembled individually for multi-directional side inspection; 2) The evaporator inside the ceiling cavity can be cleaned by disassembling the surrounding panels; 3) The drain pump assembly is fixed to the surrounding panels, making it easy to disassemble and assemble individually.

[0088] 3. Manufacturability: The separate enclosure panels and chassis foam make processing simple; at the same time, the storage space is small and the transportation is convenient; during production, staggered assembly can be carried out, with pre-assembly and final assembly carried out in stages, and the enclosure panels and foam installed simultaneously.

[0089] 4. Layout: The overall layout scheme is feasible, after the support column frame is built, the layout of the coaming, foam, hook, and water pump assembly can be adjusted and optimized, and the manufacturability and installation are enhanced.

[0090] The above merely describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
