Technical Field

[0001] This invention relates to the field of household appliances, and more specifically, to a ceiling-mounted air conditioner. Background Technology

[0002] With the development of society, the application of ceiling-mounted air conditioners is becoming more and more widespread. However, the prior art discloses a ceiling-mounted air conditioner, including a heat exchanger, which extends circumferentially along the ceiling-mounted air conditioner and forms a first end and a second end spaced apart; a fixing member, which is located between the two ends of the heat exchanger, the first end is snapped to the fixing member, and the side of the fixing member facing the second end is connected to the second end. The prior art has the following problems: (1) Both ends of the evaporator are completely blocked by the fixing member, which will cause the airflow to generate a lot of noise when it comes into contact with the fixing member, which is not conducive to improving the user's comfort; (2) The wiring layout at both ends of the evaporator is relatively complicated, which brings great inconvenience during installation, maintenance or replacement; (3) The wiring hole is located at the bottom of the fixing member, the space for wiring installation in the wiring hole is limited, and when installing and maintaining the wiring of the evaporator connection plate, it is necessary to disassemble the entire evaporator connection plate, which is more troublesome to operate. Summary of the Invention

[0003] In view of this, the present invention aims to propose a ceiling-mounted air conditioner. This addresses the problems in the prior art where both ends of the evaporator are completely blocked by fixing components, causing significant noise when airflow contacts the fixing components, which is detrimental to user comfort; the complex wiring layout at both ends of the evaporator, causing great inconvenience during installation, maintenance, or replacement; and the limited space for wiring installation at the bottom of the fixing components, requiring the entire evaporator connecting plate to be disassembled for wiring installation and maintenance, making the operation cumbersome.

[0004] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0005] A ceiling-mounted air conditioner includes at least an evaporator, a fan, and a chassis. The two ends of the evaporator are connected by an evaporator connecting plate. Both the fan and the evaporator are mounted on the chassis. The evaporator connecting plate is in contact with the chassis. The height of the end of the evaporator connecting plate away from the chassis is h1, and the height of the end of the fan away from the chassis is h2, wherein h1 < 1 / 2h2.

[0006] In this setup, an evaporator connecting plate is installed at the end of the evaporator to improve the stability of both ends of the evaporator. By setting the proportional relationship between the height of the evaporator connecting plate and the chassis, and the height of the impeller and the chassis, the noise generated during the operation of the ceiling machine can be reduced, and the user comfort can be improved.

[0007] Furthermore, the evaporator connecting plate is provided with a microporous structure, which is located in the upper middle part of the evaporator connecting plate.

[0008] The microporous structure in this setup not only improves the strength of the evaporator connection plate, thereby increasing the stability of the evaporator and the evaporator connection plate, but also reduces the noise generated by the fan assembly, improving user comfort.

[0009] Furthermore, the evaporator connecting plate includes a main plate, the microporous structure is located on the main plate, and the microporous structure is located in the upper middle part of the main plate.

[0010] This setting improves the noise reduction effect of the evaporator connection plate.

[0011] Furthermore, the evaporator connecting plate is provided with a first through hole, and a circuit connector is installed in the first through hole.

[0012] This setup simplifies the wiring at both ends of the evaporator, greatly facilitating installation, maintenance, or replacement for staff.

[0013] Furthermore, the first through hole is located at one end of the evaporator connecting plate away from the chassis, and a support plate is provided near the first through hole, the support plate being used to support the circuit connector.

[0014] The support plate in this setup facilitates the installation and removal of the circuit connectors, while also increasing their stability and preventing them from shaking or falling off.

[0015] Furthermore, the evaporator connecting plate is provided with a second through hole, the second through hole having a U-shaped structure, and the first through hole being disposed within the U-shaped structure of the second through hole.

[0016] The second through hole in this setting not only reduces the noise of the evaporator during operation, but also facilitates the routing of pipes or lines, and makes it easier to install and maintain the evaporator connection plate.

[0017] Furthermore, the evaporator connecting plate includes a first side plate, and the first through hole and the second through hole are located on the first side plate.

[0018] Furthermore, the evaporator connecting plate is provided with a wire-passing hole, which is located at the end of the evaporator connecting plate away from the chassis.

[0019] The cable routing holes in this setup facilitate the placement of the ceiling-mounted unit's cables and make it convenient for the installation and maintenance of the evaporator connection plate.

[0020] Furthermore, the evaporator connecting plate includes a second side plate, the wire passage hole is located on the second side plate, and the wire passage hole is located on the side of the second side plate away from the chassis.

[0021] Furthermore, the evaporator connecting plate is provided with reinforcing ribs, which are transverse groove structures and are located in the lower middle part of the evaporator connecting plate.

[0022] The reinforcing ribs in this design not only increase the strength of the evaporator connecting plate, but also make the internal structure of the evaporator clearer, and also hinder the transmission of noise and reduce the diffusion of noise, thereby reducing noise.

[0023] Compared with existing technologies, the ceiling machine described in this invention has the following advantages:

[0024] 1) This invention improves the robustness of both ends of the evaporator by setting an evaporator connecting plate at the end of the evaporator. By setting the proportional relationship between the height of the evaporator connecting plate and the chassis and the height of the impeller and the chassis, the noise generated during the operation of the ceiling machine can be reduced and the user comfort can be improved.

[0025] 2) By setting a microporous structure on the evaporator connecting plate, the present invention can not only improve the strength of the evaporator connecting plate, thereby increasing the stability of the evaporator and the evaporator connecting plate, but also reduce the noise generated by the fan assembly and improve user comfort.

[0026] 3) By setting circuit connectors, reinforcing ribs and wire holes on the evaporator connection plate, the present invention simplifies the wiring layout at both ends of the evaporator, bringing great convenience to the staff during installation, maintenance or replacement.

[0027] 4) The wire hole of this invention is located at the bottom of the fixing part, so that when installing and maintaining the wiring of the evaporator connecting plate, the entire evaporator connecting plate does not need to be disassembled, making the operation simpler.

Furthermore, a brief explanation of the orientations involved in the following specific embodiments is provided: the directions or positional relationships indicated by "up," "down," "left," "right," etc., mentioned in the embodiments refer to the orientations or positional relationships shown in the accompanying drawings.

[0037] Example 1

[0038] This invention proposes a ceiling machine, such as Figure 1-6 As shown, the ceiling-mounted air conditioner includes at least an evaporator 1, a fan 2, a chassis 3, and a water pump 7. The evaporator 1 extends circumferentially along the ceiling-mounted air conditioner and forms a first end 111 and a second end 141 spaced apart. Please refer to [reference needed]. Figure 3The evaporator 1 includes a straight first heat exchange channel 11, a second heat exchange channel 12, a third heat exchange channel 13, and a fourth heat exchange channel 14. The first heat exchange channel 11 and the second heat exchange channel 12 are connected by a straight section 15. The second heat exchange channel 12 is connected to the third heat exchange channel 13, and the third heat exchange channel 14 is connected to the fourth heat exchange channel 15 by arc-shaped sections. The first end 111 is located at the end of the first heat exchange channel 11 away from the straight section 15. The water pump 7 is located outside the straight section 15 of the evaporator 1. The evaporator 1 is mounted on a chassis 3. The impeller 2 is located inside the evaporator 1 and is mounted on the chassis 3. The upper end of the impeller 2 is at a height h2 from the chassis 3. The two ends of the evaporator 1 are connected by an evaporator connecting plate 4. The bottom end of the evaporator connecting plate 4 contacts the chassis, and the upper end of the evaporator connecting plate 4 is at a height h1 from the chassis 3, where h1 < 1 / 2h2. (Please refer to [reference needed]). Figure 1 Preferably, 1 / 5 < h1 / h2 < 1 / 2.

[0039] In an embodiment of the present invention, an evaporator connecting plate is provided at the end of the evaporator to improve the robustness of both ends of the evaporator. By setting the proportional relationship between the height of the evaporator connecting plate and the chassis, and between the impeller and the chassis, the noise generated during the operation of the ceiling machine can be reduced, and the user comfort can be improved.

[0040] Specifically, the first end 111 is connected to the evaporator connecting plate 4, and the side of the evaporator connecting plate 4 facing the second end 141 is connected to the second end 141.

[0041] In some embodiments of the present invention, connecting plates are provided at both ends of the evaporator. The two ends of the evaporator connecting plates are connected to the connecting plates at both ends of the evaporator. The connection method can be either snap-fit ​​fixing or bolt connection. Preferably, both ends of the evaporator connecting plates and the connecting plates at both ends of the evaporator are provided with through holes, and screws are inserted into these through holes to connect the two ends of the evaporator connecting plates to the connecting plates at both ends of the evaporator. This arrangement reduces the complexity of installing the evaporator connecting plates and the evaporator while ensuring a secure connection between them.

[0042] Please refer to Figure 4In some embodiments of the present invention, the evaporator connecting plate 4 includes a main body plate 41, on which a microporous structure 411 is provided. The microporous structure 411 is located in the upper middle part of the main body plate 41. In this embodiment, the upper middle part refers to the position slightly above the middle of the main body plate 41 or the evaporator connecting plate, that is, near the top of the main body plate 41 or the evaporator connecting plate. The microporous structure can be designed in a multi-row structure. The microporous structure can not only improve the strength of the evaporator connecting plate, thereby increasing the stability of the evaporator and the evaporator connecting plate, but also reduce the noise generated by the fan assembly and improve user comfort.

[0043] Preferably, the microporous structure is located in the middle of the main plate, and the microporous structure is formed by two rows of micropores, with the spacing between any adjacent micropores being consistent.

[0044] Please refer to Figure 5 In some embodiments of the present invention, the evaporator connecting plate 4 includes a main body plate 41, the main body plate 41 being connected to a first side plate 42 and a second side plate 43, the first side plate 42 being near a first end 111, and the second side plate 43 being near a second end 141. The structure formed by the first side plate 42, the main body plate 41, and the second side plate 43 is a protruding structure towards the impeller. A first through hole 421 is provided on the first side plate 42. The first through hole 421 is located at the end of the first side plate 42 away from the chassis 3. A circuit connector 5 is installed in the first through hole 421. Preferably, the circuit connector 5 is a mating terminal. Since the structure formed by the first side plate, the main plate, and the second side plate is a structure protruding towards the impeller, when the impeller rotates, the airflow will not directly hit the circuit connector, improving the reliability of the wiring terminal. In addition, the first through hole and the circuit connector on the evaporator connection plate of the present invention can facilitate the electrical connection of both ends of the evaporator with the external circuit, improving the electrical connectivity and reliability of the entire system. Furthermore, the presence of the circuit connector can avoid cumbersome wiring operations at both ends of the evaporator, greatly simplifying the installation process. If the evaporator malfunctions and needs to be repaired or replaced, the presence of the circuit connector can avoid affecting the entire circuit system, improving the maintainability of the equipment.

[0045] Preferably, the structure of the first through hole is consistent with the outer structure of the circuit connector, which facilitates the placement of the circuit connector inside the first through hole.

[0046] Please refer to Figure 4 , Figure 5 , Figure 6In some embodiments of the present invention, a support plate 422 is provided on the first side plate 42. The support plate 422 is located at the lower end of the first through hole 421 and is disposed on the side of the first side plate 42 away from the impeller 2. The support plate in this arrangement can improve the stability of the circuit connector, thereby improving the electrical connectivity and reliability of the entire system.

[0047] Please refer to Figure 4 In some embodiments of the present invention, the first side plate 42 is further provided with a second through hole 423, the second through hole 423 having a U-shaped structure, and the first through hole 421 being disposed within the U-shaped structure of the second through hole 423. This U-shaped structure of the second through hole 423 not only reduces the noise during operation of the evaporator, but also facilitates the routing of pipes or lines, and the installation and maintenance of the evaporator connection plate.

[0048] In some embodiments of the present invention, the second through hole 423 includes a first segment 4231, a second segment 4232, and a third segment 4233 connected in sequence. The first segment 4231 and the third segment 4233 are located on both sides of the first through hole 421, and the second segment is located at the lower end of the first through hole. The support plate 422 is disposed between the first segment 4231 and the third segment 4233, and the lower end of the support plate 422 is the second segment 4232.

[0049] Please refer to Figure 5 In some embodiments of the present invention, a wiring hole 431 is provided at the end of the evaporator connecting plate away from the chassis. The wiring of the ceiling machine can pass through the wiring hole for routing without needing to be routed inside the ceiling machine, which facilitates the arrangement of the wiring of the ceiling machine. Further, the wiring hole 431 is provided on the second side plate 43. The side of the wiring hole 431 away from the main body plate 41 has an arc-shaped structure, which facilitates the insertion of the wiring into the wiring hole. A wire clamp 4311 is provided on the side of the wiring hole near the main body plate. The wire clamp 4311 is provided to fix the wiring and prevent the wiring from becoming loose.

[0050] Please refer to Figure 5 In some embodiments of the present invention, the evaporator connecting plate 4 is provided with a reinforcing rib 46. The reinforcing rib 46 is located on the side of the evaporator connecting plate away from the impeller. The reinforcing rib 46 has a transverse groove structure and is located in the lower middle part of the evaporator connecting plate 4. The lower middle part refers to the lower center of the evaporator connecting plate 4, that is, the position near the bottom of the evaporator connecting plate. The end of the reinforcing rib 46 away from the second side plate 43 is close to the second through hole. This reinforcing rib not only improves the overall strength of the evaporator connecting plate, but also hinders the propagation of noise and reduces the diffusion of noise, thereby reducing noise. Further, the reinforcing rib 46 is recessed along the side of the evaporator connecting plate 4 away from the impeller towards the impeller.

[0051] Specifically, one end of the reinforcing rib 46 is disposed on the first side plate 42, and the other end of the reinforcing rib 46 extends to the second side plate 43. The reinforcing rib 46 is disposed at the lower end of the wire hole, the micro-hole structure, the first through hole, and the second through hole.

[0052] Preferably, one end of the reinforcing rib 46 is disposed at the lower end of the wire hole 431, and the other end of the reinforcing rib 46 extends to the lower end of the second through hole 423.

[0053] In some embodiments of the present invention, the evaporator connecting plate further includes a first flange 44 and a second flange 45, wherein the first flange 44 is connected to the first side plate 42 and the second flange 45 is connected to the second side plate 43.

[0054] Specifically, the first flange 44 is provided with a first connecting hole 441, and the first flange is connected to the connecting plate of the first end 111 by inserting a screw into the first connecting hole. The second flange 45 is provided with a second connecting hole 451, and the second flange is connected to the connecting plate of the second end 141 by inserting a screw into the second connecting hole.

[0055] Please refer to Figure 2 In some embodiments of the present invention, the ceiling machine is further provided with a surrounding plate 6, which surrounds the outer edge of the evaporator 1 and is fixed to the chassis 3. The gas entering the ceiling machine exchanges heat through the evaporator. The surrounding plate isolates and protects the evaporator, so that the evaporator has a relatively stable working environment and is not affected by the external temperature.

[0056] Specifically, the water pump 7 is located within the space formed by the enclosure 6, the chassis 3, and the straight section 15 of the evaporator.

[0057] Please refer to Figure 2 In some embodiments of the present invention, the ceiling machine is further provided with an evaporator fixing member 8. One end of the evaporator fixing member 8 is disposed on the evaporator 1, and the other end of the evaporator fixing member 8 is disposed on the chassis 3. The evaporator fixing member can not only fix the evaporator, but also play a role in turbulence and reduce the noise generated when the ceiling machine is working.

[0058] In some embodiments of the present invention, the ceiling machine is further provided with a heating element 9, which is disposed inside the evaporator, and multiple heating elements 9 are provided.

[0059] While the present invention has been disclosed above, it is not limited thereto.
