Description

Technical Field

[0001] This invention relates to the field of air conditioning, and more specifically, to a ceiling-mounted air conditioner with an electric heating function. Background Technology

[0002] Currently, for air conditioners equipped with electric heating, in order to ensure the safe operation of the electric heating, sensors are usually installed on the electric heating to collect temperature data, and a controller is used to control the operation of the electric heating based on the collected temperature to prevent accidents such as fires. However, the existing sensors on the electric heating are complex and have low safety, and the electric heating is located in the direct section of the evaporator, occupying a lot of space. Therefore, it is of great significance to study how to optimize the setting of the electric heating device in the ceiling unit in order to improve the safety of the electric heating device.

[0003] Existing built-in air conditioners often use electric heating devices installed in the straight section of the evaporator, and these devices are directly installed on the bottom inside the air conditioner casing. This can easily result in the electric heating device occupying a large space, affecting the installation of other components inside the air conditioner casing.

[0004] Furthermore, patent CN109780637A mentions a heating assembly, an electric heating device, and a ceiling machine. The heating assembly includes a bracket, a PTC heater, a mounting bracket, a first fuse, and a temperature controller. The bracket is used to mount the PTC heater on a mounting plate. The PTC heater is mounted on the bracket, and the mounting bracket is mounted on the bracket and located on the surface of the PTC heater. The first fuse and the temperature controller are mounted on the mounting bracket and are electrically connected to the PTC heater. The electric heating device includes a mounting plate and multiple heating assemblies mounted on the mounting plate. The bracket is mounted on the mounting plate. This design can solve the problems of complex and low-safety issues associated with existing electric heating devices equipped with sensors. However, the layout of the pressure plate and the electric heating device is cumbersome. When the pressure plate needs to be disassembled and rewiring, the location of the electric heating device can easily affect the disassembly and rewiring of the pressure plate, thereby reducing the disassembly efficiency of the ceiling machine.

[0005] Patent CN208579412U mentions a ceiling-mounted air conditioner, comprising: a housing; an airflow drive component, at least a portion of which is disposed within the housing; a heat exchange component, at least a portion of which is disposed within the housing and surrounds the airflow drive component; a heating component, at least a portion of which is disposed within the housing and surrounds the airflow drive component, and the heating component is connected to a wiring harness; a controller connected to the heating component; and a wiring harness positioning component connected to the housing, wherein the wiring harness is positioned by the wiring harness positioning component. The arrangement of these components can reduce the impact on airflow efficiency and improve safety performance. However, the wire clamping plate in this application is located below the airflow drive component, and the heat exchange component surrounds the airflow drive component, which still easily causes the problem of inconvenient installation and removal of the wire clamping plate. Summary of the Invention

[0006] In view of this, the present invention aims to propose a ceiling air conditioner with electric heating function to solve the problems of the cumbersome internal layout of existing ceiling air conditioners, especially the large space occupied by the electric heating device and the pressure plate, as well as the low disassembly and assembly efficiency of the ceiling air conditioner. This invention optimizes the placement of the electric heating device and the pressure plate, improves the component layout inside the ceiling air conditioner, saves space occupied by the electric heating device and the pressure plate, increases the heat exchange efficiency inside the ceiling air conditioner, and also helps to improve the disassembly and assembly efficiency of the ceiling air conditioner and reduce the maintenance cost of the ceiling air conditioner.

[0007] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0008] This invention relates to a ceiling-mounted air conditioner with electric heating function, comprising a housing, an evaporator, a water pump, a fan, an electric heating device, and a pressure wire device. The evaporator, water pump, and fan are all located inside the housing. The electric heating device and the pressure wire device are both located inside the housing via a base foam. The electric heating device and the pressure wire device are arranged alternately around the fan. This staggered arrangement effectively avoids overlap and mutual interference between the pressure wire device and the electric heating device, thus preventing them from affecting the assembly and disassembly efficiency of the ceiling-mounted air conditioner. Furthermore, the auxiliary effect of the base foam can improve the safety of the operation of the internal devices of the ceiling-mounted air conditioner, and also facilitates the isolation between devices, effectively preventing mutual interference between the various components inside the ceiling-mounted air conditioner, improving the independence of the devices, saving space in the internal cavity of the ceiling-mounted air conditioner, and enhancing heat exchange efficiency.

[0009] Furthermore, the housing includes a housing cover plate and housing side plates. The housing cover plate is located on top of the housing side plates, and the inner sides of the housing cover plate and housing side plates form an inner cavity for installing the internal components of the ceiling-mounted unit. The housing side plates include a first side plate, a second side plate, a third side plate, a folded side plate, and a lifting lug panel. The two ends of the first side plate perpendicular to one side of the housing cover plate are respectively connected to one end of the second side plate and the folded side plate through the lifting lug panel. The other ends of the second side plate and the folded side plate are respectively connected to the third side plate through the lifting lug panel. Limiting blocks are provided on the inner sides of the first side plate, the second side plate, the third side plate, and the folded side plate to limit the outer side of the evaporator. By setting each side plate inside the housing, the overall size of the housing can be reduced, which is beneficial for the packaging and handling of the ceiling-mounted unit, and can also reduce packaging costs and improve the disassembly and assembly efficiency of the device. In addition, the setting of the limiting blocks can also provide support and limit the evaporator, avoiding direct contact between the evaporator and the housing, which would affect the heat exchange efficiency.

[0010] Furthermore, the evaporator is conformally arranged along the inner side of the shell side plate, with one end of the evaporator located in front of the folded side plate and the other end located on the right side of the first side plate. A supporting limiting plate is provided between the two ends of the evaporator. The evaporator includes straight sections and curved sections, with both ends being straight sections. The straight sections and curved sections are staggered, and the positions of the straight sections correspond to the positions of the first side plate, second side plate, third side plate, and folded side plate, respectively. The straight sections at both ends of the evaporator are connected by the supporting limiting plate. The evaporator and the inner side of the supporting limiting plate form a cavity, which houses the fan, electric heating device, pressure wire device, and bottom. The foam discs are all placed inside the cavity. The staggered arrangement of straight and curved sections within the evaporator ensures that the length of the existing evaporator remains essentially unchanged, thus maintaining the same heat exchange capacity. This allows the ends of the evaporator to accommodate the water pump and inlet / outlet pipes, greatly facilitating the installation and maintenance of the water pump. Furthermore, installing the water pump at the end of the evaporator does not disrupt the uniformity of airflow within the exhaust duct, resulting in more even heat distribution from the ceiling unit and ensuring that the air temperature from different areas of the ceiling unit is the same, thus improving user comfort.

[0011] Furthermore, at least one electric heating device and one pressure-line device are provided. The electric heating device is located inside the arc segment, and its location corresponds to the arc segment position. The pressure-line device is located inside the straight segment, and its location corresponds to any one of the first, second, and third side plates, or any multiple locations of the first, second, and third side plates. Through the placement of the electric heating device and the installation structure, the internal space of the ceiling machine can be effectively saved, the internal heat exchange efficiency of the ceiling machine can be improved, and the heat exchange effect of the ceiling machine can be greatly enhanced.

[0012] Compared with the prior art, the ceiling heating machine with electric heating function described in this invention has the following beneficial effects:

[0013] The arrangement of the various components inside the ceiling machine helps to optimize the placement of the electric heating device and the pressure plate device, improve the component layout inside the ceiling machine, save the space occupied by the electric heating device and the pressure plate device inside the ceiling machine, increase the heat exchange efficiency inside the ceiling machine, and also help to improve the disassembly and assembly efficiency of the ceiling machine and reduce the maintenance cost of the ceiling machine.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] This embodiment is for an air conditioner. Similar to a conventional air conditioner, the overall structure consists of a motor and an evaporator.

[0027] In the existing technology, for air conditioners equipped with electric heating, in order to ensure the safe operation of electric heating, a sensor for collecting the electric heating temperature is usually installed on the electric heating, and a controller is used to control the operation of electric heating according to the collected temperature to prevent accidents caused by electric heating, such as fires. However, the existing electric heating with sensor is complicated and has low safety, and the electric heating is placed in the direct section of the evaporator, occupying a lot of space.

[0028] To address the problems of cumbersome internal layout of existing ceiling heaters, particularly the large space occupied by the electric heating device 5 and the pressure plate, as well as the low assembly and disassembly efficiency, this embodiment proposes a ceiling heater with electric heating function.

The electric heating device 5 and pressure plate 6 are arranged alternately around the fan 4. In this embodiment, "outside" refers to the side of the housing 1 exposed to air, and "inside" is the opposite direction to the outside.

[0029] The internal layout of the ceiling machine optimizes the placement of the electric heating device 5 and the wire pressing device 6, improves the component layout within the ceiling machine, saves space occupied by the electric heating device 5 and the wire pressing device 6, increases the heat exchange efficiency within the ceiling machine, improves the assembly and disassembly efficiency of the ceiling machine, and reduces the maintenance cost of the ceiling machine. The use of chassis foam 7 helps to improve the stability and safety of the installation of the electric heating device 5 and the wire pressing device 6, while also effectively protecting other components, improving the heat insulation effect, and protecting the internal wiring of the ceiling machine from damage.

[0030] The housing 1 includes a housing cover plate 11 and a housing side plate 12. The housing cover plate 11 is disposed on top of the housing side plate 12.

The folding side panel 124 includes a first side panel 1241, a second side panel 1242, and a third side panel 1243, which are integrally formed and connected by arcs in sequence. The first side panel 1241 is located away from the side panel 1242. One end of the second plate 1242 is connected to the lifting lug panel 125 near the first side plate 121 by an arc. The end of the third side plate 1243 away from the second side plate 1242 is connected to the lifting lug panel 125 near the third side plate 123 by an arc. A first cavity is formed between the first side plate 121, the folded side plate 124, the evaporator 2, and the support limiting plate 23. A water pump 3 is installed in the first cavity. In this embodiment, "top" refers to the upper surface of the object in the figure, and "bottom" refers to the lower surface of the object in the figure.

[0031] The design of the shell 1 structure helps to optimize the overall size of the shell 1, facilitates packaging and handling, reduces the packaging cost of the device, and improves the disassembly and assembly efficiency of the device. In addition, the use of the folded side plate 124 helps to reduce the space occupied by the ceiling-mounted machine shell and can also provide a limiting function for the installation of the water pump 3. The setting of the limiting block 13 also helps to provide support and limit the setting of the evaporator 2, avoiding direct contact between the evaporator 2 and the shell 1, which would affect the heat exchange efficiency.

[0032] The evaporator 2 is conformally arranged along the inner side of the shell side plate 12. One end of the evaporator 2 is located in front of the folded side plate 124, and the other end of the evaporator 2 is located on the right side of the first side plate 121. A support and limiting plate 23 is provided between the two ends of the evaporator 2 to fix and limit the inner side of the evaporator 2. One end of the evaporator 2 is parallel to the folded side plate 124, and the other end of the evaporator 2 is parallel to the first side plate 121. The evaporator 2 includes a straight section 21 and an arc section 22. Both ends of the evaporator 2 are set as straight sections 21, and the straight sections 21 and arc sections 22 are staggered. The positions of the straight sections 21 are respectively set with the first side plate 121, the second side plate 122, the third side plate 123, and the folded side plate 124. Correspondingly, the straight sections 21 at both ends of the evaporator 2 are connected by support limiting plates 23; the evaporator 2 and the inner side of the support limiting plates 23 form a cavity 24, and the fan 4, electric heating device 5, pressing device 6, and chassis foam 7 are all arranged inside the cavity 24; the straight section 21 includes a first straight section 211, a second straight section 212, a third straight section 213, and a fourth straight section 214. The first straight section 211 is arranged parallel to the inner side of the first side plate 121, the second straight section 212 is arranged parallel to the inner side of the second side plate 122, the third straight section 213 is arranged parallel to the inner side of the third side plate 123, and the fourth straight section 214 is arranged parallel to the inner side plate 124. One end of the first straight section 211 is connected by the support limiting plate 23. One end of the straight section 214 is connected to the fourth straight section 214, and the other end of the first straight section 211 is connected to one end of the second straight section 212 via an arc segment 22. The other ends of the second straight section 212 and the fourth straight section 214 are respectively connected to both ends of the third straight section 213 via arc segments 22. In addition, a fixing bracket 25 is provided on the side of the third straight section 213 near the second straight section 212. One end of the fixing bracket 25 is fixed to the shell cover plate 11 of the shell 1 via the base foam 7, and the other end of the fixing bracket 25 is snapped into the bottom of the evaporator 2 to fix the evaporator 2. This is to avoid the possibility of poor stability of the evaporator 2 during operation due to the excessive length of the evaporator 2 and the limited number of fixing positions. In this embodiment, In the process, the radius of arc segment 22 is set as required, and the lengths of straight segment 211, straight segment 212, straight segment 213, and straight segment 214 are set as required. The length from the outer wall of straight segment 211 to the end of straight segment 214 is denoted as L1, and the length from the outer wall of straight segment 214 to the end of straight segment 211 is denoted as L2. L1 / L2 > 1.

[0033] By using the straight section 21 and the arc section 22 inside the evaporator 2, the evaporation effect of the evaporator 2 can be effectively improved while reducing the space occupied by the evaporator 2 in the ceiling machine's internal cavity. In addition, the cooperation between the support limiting plate 23 and the limiting block 13 helps to fix and limit the evaporator 2 from both inside and outside, thereby improving the stability of the evaporator 2 installation and preventing vibration during the operation of the ceiling machine from causing the internal components of the ceiling machine to shift. The setting of the support limiting plate 23 can also effectively reduce the size of the internal support components of the evaporator 2 and block the water pump 3, improving the safety of the internal fan 4, electric heating device 5, pressure wire device 6, and chassis foam 7 of the ceiling machine. In addition, the setting of the limiting block 13 can also help to fix the evaporator 2 and the... The gaps formed between the shells 1 facilitate heat dissipation of the evaporator 2, preventing overheating damage to internal components and thus greatly improving the safety and reliability of the internal components. Furthermore, the staggered arrangement of the straight section 21 and the curved section 22 of the evaporator 2 ensures that the length of the evaporator 2 remains essentially unchanged, maintaining its heat exchange capacity while allowing the water pump 3 and inlet / outlet pipes to be accommodated at the end of the evaporator 2. This greatly facilitates the installation and maintenance of the water pump 3. Additionally, installing the water pump 3 at the end of the evaporator 2 does not disrupt the uniformity of airflow within the exhaust duct, resulting in more even heat distribution from the ceiling unit and ensuring consistent air temperature across different areas, thus improving user comfort.

[0034] The shape of the base foam 7 is consistent with the top shape of the cavity 24. The base foam 7 is provided with clearance notches 71 to facilitate the installation of the electric heating device 5, the wire pressing device 6, and the fan 4. At least one clearance notch 71 is provided, including clearance notch one, clearance notch two, clearance notch three, and clearance notch four.

An installation channel is provided, with three notches to provide an installation channel for the fan 4 and four notches to provide an installation channel for the fixed bracket 25. At least one electric heating device 5 and one wire clamping device 6 are each provided. The electric heating device 5 is positioned corresponding to the position of the arc segment 22, and is located inside the arc segment 22. The projected shape of the electric heating device 5 is square or arc-shaped. The projected shape of the electric heating device 5 is square, as shown in the figure. The electric heating device 5 is located inside the arc segment 22, and the plane where the long side of the electric heating device 5 is located is aligned with the plane of the straight section 2 of the evaporator 2. The included angle is α, and the value of α ranges from (0° to 90°). The projected shape of the electric heating device 5 is arc-shaped. The electric heating device 5 and the arc segment 22 are set according to the shape, and there is a certain gap between the electric heating device 5 and the arc segment 22. The setting of the electric heating device 5 helps to save space inside the ceiling machine and increase the heat exchange efficiency of the evaporator 2. In addition, the electric heating device 5 includes an electric heater 51 and a support column 52. The electric heater 51 is connected to the support column 52 by screws. The support column 52 is set at the bottom of the shell cover plate 11 on the top of the shell 1 through a notch in the chassis foam 7. The shape of the opening of the part that avoids the notch is consistent with the shape of the bottom of the electric heating device 5, so as to facilitate the passage of the end of the support column 52 of the electric heating device 5 near the housing 1; the electric heater 51 includes an electric heating element and a heating bracket, at least two heating brackets are provided, the electric heating element is provided on the inner side of the two heating brackets, the two heating brackets are respectively connected to the support column 52 by screws, the support column 52 includes a support body and a support base plate, the top of the support body is fixedly set at the bottom of the housing cover plate 11 through the support base plate, and the top of the support body is also inserted through the notch through the support base plate;The wire pressing device 6 is located inside the straight section 21. The position of the wire pressing device 6 corresponds to any one of the following three side plates: 121, 122, and 123; or multiple positions of the wire pressing device 6 correspond to any of these three side plates. The wire pressing device 6 is a wire pressing buckle used to organize and manage the connecting wires of the internal components of the ceiling machine. The wire pressing device 6 is located at the bottom of the housing cover plate 11 on the top of the housing 1 through two clearance notches. The opening shape of the clearance notches is consistent with the bottom shape of the wire pressing device 6, allowing the end of the wire pressing device 6 near the housing 1 to pass through. Preferably, three electric heating devices 5 and three wire pressing devices 6 are provided. The three heating elements 5 are respectively set inside the three arc segments 22.

The three pressing devices 6 and the three electric heating devices 5 are arranged alternately around the outside of the fan 4. The fan 4 is set at the bottom of the shell cover plate 11 on the top of the shell 1 through the avoidance three notches. The opening shape of the avoidance three notches is consistent with the bottom shape of the fan 4, which is used to facilitate the installation of the fan 4 near the end of the shell 1. The opening shape of the avoidance four notches is consistent with the bottom shape of the fixing bracket 25, which is used to facilitate the installation of the fixing bracket 25 near the end of the shell 1.

[0035] By using a special configuration of the electric heating device 5, unlike the prior art where the electric heating device 5 is located inside the straight section 21 of the evaporator 2, which not only occupies a large amount of space inside the ceiling machine but also restricts the placement of the pressure clips, resulting in poor layout stability of the various components inside the ceiling machine and failing to effectively achieve the stability and reliability of the ceiling machine's operation, the electric heating device 5 in this application adopts a detachable configuration of the electric heater 51 and the support column 52. This can improve the installation efficiency of the electric heating device 5 during installation and reduce the size of the opening of the avoidance notch on the chassis foam 7, thereby enhancing the strength of the chassis foam 7. This avoids the problem of low structural strength of the chassis foam 7 due to too many openings in the avoidance notch 71, effectively enhancing the protection of the chassis foam 7 for the various components inside the cavity 24 and improving the stability and safety of the various components inside the ceiling machine.

[0036] In this invention, any air conditioner may include the hanging ear device structure of a ceiling-mounted unit as described in this embodiment. In addition to the electric heating device 5 and the related structure and assembly relationship of the pressure plate provided in this embodiment, the air conditioner also includes conventional components such as a motor and an evaporator 2. Since these are all prior art, they will not be described in detail here.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
