Description

Technical Field

[0001] The invention relates to the technical field of air conditioning equipment, and in particular to a novel ceiling internal machine frame structure and an air conditioner. Background Art

[0002] like Figures 1-2 As shown, during the overall assembly of the commercial air-conditioning ceiling unit, the chassis 1 is fixed by a panel device 2 formed by multiple panels (such as panel A2a and panel B2b) to support and build the ceiling frame, and then the water tray 6, chassis foam 4 and other structures and system parts are assembled to complete the internal closed and heat-insulating space. Multiple panels are fixed along the edge of the chassis with universal screws to form the outer and bottom structures, and the water tray 6 is fixed to the panel device 2 by screws to form an embedded assembly.

[0003] In the actual manufacturing and assembly process, there are the following shortcomings:

[0004] 1. Strength risk: The area of ​​the enclosure is large. Considering the material cost, the thickness is generally small. The vertical support strength through the thickness of the surrounding enclosure is poor:

[0005] 1) The panel is integrally formed, the sheet metal is deformed, and parts assembly is prone to deformation and gaps;

[0006] 2) The upper and lower parts are connected only by the enclosure device 2 without strong support points, which may easily cause overall deformation and depression during actual transportation, falling, and stepping;

[0007] 3) During hoisting, the hook assembly 3 is subjected to great force, and the fixed support close to the coaming board may easily cause the coaming board to be deformed due to the force;

[0008] 4) When the internal machine is running, the vibration of the motor is transmitted to the integral enclosure device 2 through the chassis 1, which is prone to generate resonance noise.

[0009] 2. Difficulty of maintenance: There are many disassembly processes and parts when inspecting and repairing the interior through the surrounding panels and the overall frame:

[0010] 1) When checking and cleaning the evaporator 8 when there is an internal fault in the ceiling machine, it is necessary to disassemble the panel, guide ring, electric control box, and even the water tray 6;

[0011] 2) It is impossible to disassemble and inspect the ceiling machine from the side;

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

[0013] 3. Poor manufacturability: The overall enclosure is difficult to process and transport (sheet metal deformation), and is easily deformed during the assembly process. The overall storage space and transportation of chassis foam 4 incoming materials are difficult.

[0014] 4. Layout: The ceiling machine circle relies on the overall support of the enclosure, and the layout is limited. The enclosure strength cannot independently meet the hook hoisting support function, and the hook component 3 that still meets the hoisting function is still required. The chassis foam 4 needs the overall structure to cooperate with the water pump installation and play an auxiliary support role. The drainage pump device 5 is fixedly installed on the chassis foam 4, which is difficult to install and disassemble. Summary of the invention

[0058] Example 1

[0059] like Figures 3 to 12 As shown, the present invention discloses a novel ceiling internal machine frame structure, including a chassis 1, a water receiving tray 6 and a support column assembly 7. The support column assembly 7 is provided in plurality, and the upper and lower ends of the plurality of support column assemblies 7 are detachably connected to the water receiving tray 6 and the chassis 1 respectively.

[0060] The novel ceiling indoor machine frame structure disclosed in the present application builds a strong support column frame structure by setting up a support column assembly 7 in combination with a chassis 1 and a water collecting pan 6, thereby completing the fixation and assembly of the overall structure and improving the overall strength of the ceiling indoor machine frame structure. At the same time, when the ceiling indoor machine is running, the chassis is subjected to force vibration, and the support column assembly 7 is used to connect the water collecting pan 6 and the chassis 1. When the motor vibration is transmitted to the chassis, the transmission structure of the chassis vibration is changed. At the same time, the weight of the object also changes when it is transmitted to the support column assembly 7, which can effectively change the vibration frequency and improve the fixed frequency resonance deformation phenomenon.

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

[0062] As a preferred example of the present application, the support column assembly 7 includes a support body 71, a first connecting plate 76 is arranged at the upper end of the support body 71, the first connecting plate 76 is detachably connected to the water tray hook 61 on the water tray 6 by a first fixing screw 77, and the lower end of the support body 71 is detachably connected to the chassis 1 by a second fixing screw 78. In the novel ceiling internal machine frame structure disclosed in the present application, the water tray 6 is fitted with the support body 71 of the support column assembly 7 from top to bottom, the water tray hook 61 overlaps the first connecting plate 76 at the upper end of the support body 71 and is fastened by a first fixing screw 77, and the lower end of the support body 71 is attached to the chassis 1 and fastened by a second fixing screw 78, as shown in FIG. Figure 7 As shown, the upper and lower supporting fixed frames are constructed.

[0063] As a preferred example of the present application, a hook connection portion 72 is provided near the middle of the support body 71, and the hook connection portion 72 is detachably connected or welded to the support body 71. Figure 7 As shown, a fourth connection hole 74 is provided on the support body 71, and the fourth connection hole 74 is screwed or welded to the support body 71. Preferably, the hook connection part 72 is spot welded on the support body 71. This arrangement integrates the hanging structure of the ceiling machine on the support column assembly 7, simplifies the structural design, ensures the reliability of the overall hanging of the ceiling machine, and reduces the deformation problem that may exist in the enclosure.

[0064] As a preferred example of the present application, a panel device 2 is provided between the chassis 1 and the water receiving tray 6, and the panel device 2 is detachably connected to the support body 71. Specifically, the panel device 2 includes a plurality of panels, and a connecting bent plate 2h is formed at the position connected to the support body 71 on each panel, and a first connecting hole 2e and a second connecting hole 2f are provided on the connecting bent plate 2h. 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 respectively connected to the first connecting hole 2e and the second connecting hole 2f. Preferably, the third connecting hole 73 and the fifth connecting hole 75 are both provided on the support body 71 between the first connecting plate 76 and the second fixing screw 78, and two third connecting holes 73 and the fifth connecting hole 75 are provided on the support body 71, and the two third connecting holes 73 and the fifth connecting hole 75 are respectively connected to the first connecting hole 2e and the second connecting hole 2f on the two panels with screws. As an example of the present application, the line connecting the two third connection holes 73 is arranged horizontally, and the line connecting the two fifth connection holes 75 is also arranged horizontally.

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

[0066] As a preferred example of the present application, a first easing portion 2c is provided on the connecting bent plate 2h, and the first easing portion 2c is used to avoid the connection between the second fixing screw 78 and the chassis 1. As an example of the present application, a second easing portion 2d is provided on the connecting bent plate 2h, and the second easing portion 2d is used to avoid the connection position between the hook connecting portion 72 and the supporting body 71. Through the design of the above-mentioned easing portion, the connection operation is prevented from being interfered by the connecting bent plate 2h on the enclosure, and more operating space is provided, making it more convenient and efficient to install, remove or adjust the connecting parts, improving the operability of the connection, and improving the overall assembly and maintenance efficiency.

[0067] As a preferred example of the present application, the enclosure device 2 described in the present application includes enclosures in four directions, namely the first enclosure assembly 21, the second enclosure assembly 22, the third enclosure assembly 23 and the fourth enclosure assembly 24. Correspondingly, four support column assemblies 7 are provided, and the four support column assemblies 7 are used for sequentially connecting the first enclosure assembly 21, the second enclosure assembly 22, the third enclosure assembly 23 and the fourth enclosure assembly 24. The four support column assemblies 7 are arranged at the four corners of the inner machine frame structure.

[0068] This arrangement further limits the structure of the enclosure device 2 and the arrangement structure of the support column assembly 7 connecting the enclosure device 2. By arranging a support column assembly 7 at each of the four corners of the inner machine frame structure, a four-way strong support column structure is formed. This can prevent shaking and force deformation during operation vibration, transportation, falling, trampling, and multi-layer stacking of the ceiling machine, thereby increasing the overall structural strength.

[0069] Through the above-mentioned four-way frame support, the support column is supported by force when falling, and has high impact resistance and deformation resistance. The applicant conducted a comparative test on the falling phenomenon of the new and old structures, and the test results are shown as follows:

[0070]

[0071] In addition, when the ceiling machine is running, the chassis 1 is subjected to force vibration, and the frequency of the object's vibration is related to the structure, mass, and center of gravity of the object. Because the four-way support column is strongly fixed, when the motor vibration is transmitted to the chassis, the transmission structure of the chassis vibration is changed. At the same time, because the weight of the object changes when it is transmitted to the support column, the vibration frequency can be effectively changed.

[0072] according to Fig.13 The old architecture fixed frequency test and Fig.14 The new architecture fixed frequency test shown in Fig.13 and Fig.14 In the figure, the X-axis is frequency Hz, and the Y-axis is the fixed-frequency vibration value. When the tip of the curve in the figure coincides with 50Hz and its multiples, it is the resonance point and resonance occurs. The old structure of the ceiling indoor unit has multiple peaks at 50Hz multiples, while the peak of the new structure of the ceiling indoor unit avoids 50Hz multiples, effectively avoiding 50Hz multiples, so that the resonance noise value is also improved.

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

[0074]

[0075] The above chart is attached Fig.15 ~Attached Fig. 20 In the figure, the X-axis is the noise frequency and the Y-axis is the noise value. When the noise frequency is abnormally large at a certain value, that is, when there is an abnormal peak along the slope of the curve, it means that abnormal sound is generated in this frequency range. Figures 15 to 20 The intersection of the middle cross is the corresponding noise location.

[0076] The strong pillar new ceiling internal machine frame structure designed in this application, such as Figure 5 As shown, a support column assembly 7 is provided at each of the four azimuth angles of the chassis 1. The four-azimuth support columns are designed to be located at the center of gravity G of the balanced ceiling machine. No fixed value is set here, and a 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 and a first foam 212, the second enclosure assembly 22 includes a second enclosure 221 and a second foam 222, the third enclosure assembly 23 includes a third enclosure 231 and a third foam 232, the fourth enclosure assembly 24 includes a fourth enclosure 241 and a fourth foam 242, the first foam 212 is connected to the first enclosure 211, the second enclosure 221 is connected to the second foam 222, the third enclosure 231 is connected to the third foam 232, and the fourth enclosure 241 is connected to the fourth foam 242. The enclosure device 2 described in the present application has a foam component 10 arranged inside the enclosure device 2, and the foam component 10 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 respectively form the first enclosure component 21, the second enclosure component 22, the third enclosure component 23, and the fourth enclosure component 24 in four directions with the first enclosure 211, the second enclosure 221, the third enclosure 231, and the fourth enclosure 241. The enclosure component formed by the enclosure + foam component has sealing + heat preservation functions, and can be disassembled separately, which 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, it is necessary to disassemble the panel, the guide ring, the electric control box and other structures, and spray water from the inside to clean it. The process is cumbersome and it is very easy to damage other parts. The new ceiling internal machine frame structure described in this application can be cleaned by spraying water from the outside after removing the enclosure + insulation foam from the side. The process is simple and efficient, and it is not easy to cause water splashing to damage other parts. The schematic diagram of maintenance and cleaning is as follows: Fig.10 The structure shown, Fig.10 The arrows in the figure indicate the inspection and cleaning directions after the panels and foam are removed.

[0078] As a preferred example of the present application, the enclosure of the enclosure device 2 is preassembled with the corresponding foam in the foam assembly 10 by bonding. That is, the first foam 212 is preassembled with the first enclosure 211 by bonding, the second enclosure 221 is preassembled with the second foam 222 by bonding, the third enclosure 231 is preassembled with the third foam 232 by bonding, and the fourth enclosure 241 is preassembled with the fourth foam 242 by bonding. The enclosure and the thermal insulation foam of each enclosure assembly in the enclosure device 2 are assembled by gluing and the like, and can be installed and maintained as a whole, and the inner cavity of the ceiling can be wrapped or exposed.

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

[0080] The key to the novel ceiling internal machine frame structure described in the present invention is to use a frame-type structure to build the ceiling internal machine frame, relying on the support column assembly 7 as a load-bearing column to realize the structure, and on the basis of the external frame structure, the enclosure, water tray, water pump assembly and other structural components are fixed, the supporting strength is enhanced, and the enclosure structure can be disassembled separately.

[0081] The novel ceiling internal machine frame structure described in the present invention has the following advantages:

[0082] 1. The overall assembly strength is increased, which can provide high impact resistance and deformation resistance against falling, and can effectively improve the transmission of operating vibration and fixed frequency resonance;

[0083] 2. The enclosure assembly structure of the enclosure + thermal insulation foam can be independently loaded and unloaded, and the drainage pump assembly 9 can be independently loaded and unloaded, which improves the efficiency of after-sales maintenance and enables quick and easy disassembly and cleaning.

[0084] The present application also discloses an air conditioner, comprising a novel ceiling indoor unit frame structure as described in the above-mentioned embodiment, using four-way strong support columns to fix the chassis structure to build a frame shape, using support column components 7 strong frames to build a combined enclosure, the combined enclosure has a split structure, the foam component 10 is designed to be split corresponding to the combined enclosure, and a front combination is pre-installed (enclosure + foam, chassis, drainage pump component 9 separate valve plate structure), providing a new frame-fixed ceiling machine.

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

[0086] 1. Strength: The four-way strong support columns can prevent shaking and deformation during operation vibration, transportation, falling, trampling, and multi-layer stacking. The overall structural strength is increased. When the internal machine is running, the strong fixed structure can effectively reduce vibration transmission and the resonance noise is excellent.

[0087] 2. Easy to disassemble and clean: 1) The surrounding panels can be disassembled separately for multi-directional side inspection; 2) The evaporator in the ceiling cavity can be cleaned by disassembling the panels; 3) The drainage pump assembly is fixed to the panels and can be easily disassembled and assembled separately.

[0088] 3. Manufacturability: Split panels and chassis foam are easy to process; at the same time, the storage space is small and transportation is convenient; during production, the assembly can be staggered, and the pre-assembly + final assembly can be carried out in steps, and the panels and foam can be installed simultaneously.

[0089] 4. Layout: The overall layout plan has many feasibility. After the support column framework is built, the layout of the enclosure, foam, hook, and water pump components is adjusted and optimized, and the manufacturability and maintainability are enhanced.

[0090] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
