Description

Technical Field

[0001] This application relates to, but is not limited to, the field of air conditioning equipment technology, specifically referring to a ceiling-mounted air conditioner and an air conditioner. Background Technology

[0002] The existing ceiling-mounted ceiling machines include two types:

[0003] The first type of ceiling-mounted air conditioner includes a chassis, insulating foam, a fan assembly, and an open annular heat exchanger. The insulating foam is located inside the chassis and has a closed bottom wall and an annular peripheral wall. The bottom wall of the insulating foam completely covers the inner bottom surface of the chassis. The heat exchanger is located inside the annular peripheral wall of the insulating foam and is mounted on the bottom wall of the insulating foam. The fan assembly is located inside the heat exchanger and is fixedly connected to the chassis. To eliminate the safety hazard of the electric heating module igniting the insulating foam, this type of ceiling-mounted air conditioner cannot be equipped with an electric heating module.

[0004] The second type of ceiling-mounted air conditioner includes a chassis, insulating foam, a fan assembly, an electric heating module, and an open annular heat exchanger. The insulating foam has an annular peripheral wall, which is located around the inner bottom surface of the chassis. The heat exchanger is located inside the annular peripheral wall of the insulating foam and is mounted on the chassis. The fan assembly is located inside the heat exchanger and is fixedly connected to the chassis. The electric heating module is located between the heat exchanger and the fan assembly on the inner bottom surface of the chassis. Although this type of ceiling-mounted air conditioner is equipped with an electric heating module, and the electric heating module does not pose a safety hazard of igniting the insulating foam, condensation easily occurs on the outer bottom surface of the chassis during cooling operation. The conventional technical means in this field to solve the problem of condensation on the outer bottom surface of the chassis is to install a felt cloth on the outer bottom surface of the chassis. However, installing a felt cloth on the outer bottom surface of the chassis is easily torn during the production and installation of the ceiling-mounted air conditioner, and the felt cloth is also easily chewed and torn by rodents during long-term use. Summary of the Invention

[0005] This application provides a ceiling-mounted air conditioner, comprising: a chassis with a bottom wall, the bottom wall of the chassis having a first covering area and an installation area; an insulation component with a bottom wall disposed within the chassis, the bottom wall of the insulation component having a second covering area and a perforated area, the second covering area being positioned within the first covering area, and the perforated area being opposite to the installation area; an electric heating module disposed from the perforated area within the installation area and spaced apart from the insulation component; a cover plate having a first mounting plate segment and a second mounting plate segment, the first mounting plate segment being at least partially disposed on the side of the second covering area facing away from the first covering area, and the second mounting plate segment being at least partially disposed from the perforated area within the installation area; and a fan assembly located on the side of the cover plate facing away from the bottom wall of the chassis and connected to the bottom wall of the chassis.

[0006] In some exemplary embodiments, the ceiling fan further includes a buffer disposed between the second mounting plate segment and the mounting area, wherein the second mounting plate segment isolates the fan assembly from the mounting area.

[0007] In some exemplary embodiments, the wind turbine assembly includes a motor and a wind turbine, and the orthographic projection of the first mounting plate segment on the bottom wall of the chassis is located inside the orthographic projection of the peripheral wall of the wind turbine on the bottom wall of the chassis.

[0008] In some exemplary embodiments, the first mounting plate segment is a circular plate segment, the second mounting plate segment is an arc-shaped plate segment, the inner edge of the arc-shaped plate segment is connected to the periphery of the circular plate segment, and the two ends of the arc-shaped plate segment abut against one end of the second covered area adjacent to the hollow area.

[0009] In some exemplary embodiments, the electric heating module is disposed along the edge of the hollowed-out area away from the second covered area.

[0010] In some exemplary embodiments, both the mounting area and the hollowed-out area are triangular in shape and have a first edge, a second edge and a third edge arranged sequentially along the circumference. The second edge and the third edge of the hollowed-out area are located on the side of the first edge of the hollowed-out area away from the second covered area. The electric heating module includes two sets, both of which are in a straight line shape. The two electric heating modules are arranged one-to-one along the second edge and the third edge of the hollowed-out area.

[0011] In some exemplary embodiments, both the first covered area and the second covered area are triangular in shape, and the insulation member also has an annular peripheral wall, which is quadrilateral in shape.

[0012] In some exemplary embodiments, the cover plate is provided with a wiring structure and a wire-clamping structure, the wire-clamping structure being located between the wiring structure and the fan assembly and offset from the wiring direction of the wiring structure.

[0013] In some exemplary embodiments, the ceiling machine further includes: an open annular heat exchanger, the bottom wall of the insulation component further having a support area, the bottom wall of the chassis further having a third covering area, the shape of the support area matching the shape of the heat exchanger, the second covering area and the hollow area being located inside the support area, the support area being placed in the third covering area, and the heat exchanger being placed on the side of the support area opposite to the third covering area.

[0014] This application also provides an air conditioner, including the ceiling-mounted unit described in any of the above embodiments.

[0015] The technical solution provided in this application embodiment has a second covering area on the bottom wall of the insulation component placed within the first covering area on the bottom wall of the chassis. At least part of the second mounting plate segment of the cover plate is located in the mounting area from the perforated area. The second covering area isolates the first covering area from the cold air inside the ceiling unit, and the second mounting plate segment isolates the mounting area from the cold air inside the ceiling unit. This improves the condensation problem on the outer bottom surface of the chassis during cooling operation. The perforated area is opposite to the mounting area, and the electric heating module is located in the mounting area from the perforated area and spaced apart from the insulation component. This eliminates the safety hazard of the electric heating module igniting the insulation foam.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0028] like Figures 1 to 7 As shown in the embodiment of this application, the ceiling heating machine includes: a chassis 100 with a bottom wall, the bottom wall of the chassis 100 having a first covering area 110 and an installation area 120; a heat insulation component 200 with a bottom wall, the heat insulation component 200 being disposed within the chassis 100, the bottom wall of the heat insulation component 200 having a second covering area 210 and a hollow area 220, the second covering area 210 being positioned within the first covering area 110, and the hollow area 220 being opposite to the installation area 120; and an electric heating module 300, the electric heating module 300 being mounted from the hollow area. 220 is located in the installation area 120 and spaced apart from the insulation component 200; a cover plate 400 having a first mounting plate segment 410 and a second mounting plate segment 420, the first mounting plate segment 410 being at least partially located on the side of the second covering area 210 facing away from the first covering area 110, and the second mounting plate segment 420 being at least partially located in the installation area 120 from the hollow area 220; and a fan assembly 500, the fan assembly 500 being located on the side of the cover plate 400 facing away from the bottom wall of the chassis 100 and connected to the bottom wall of the chassis 100.

[0029] In this ceiling-mounted air conditioner, the second covering area 210 of the bottom wall of the insulation component 200 is placed within the first covering area 110 of the bottom wall of the chassis 100. The second mounting plate segment 420 of the cover plate 400 is at least partially located in the mounting area 120 from the perforated area 220. The second covering area 210 isolates the first covering area 110 from the cold air inside the ceiling-mounted air conditioner, and the second mounting plate segment 420 isolates the mounting area 120 from the cold air inside the ceiling-mounted air conditioner. This improves the condensation problem on the outer bottom surface of the chassis 100 during cooling operation. The perforated area 220 is opposite to the mounting area 120, and the electric heating module 300 is located in the mounting area 120 from the perforated area 220 and spaced apart from the insulation component 200. This eliminates the safety hazard of the electric heating module 300 igniting the insulation foam.

[0030] The cover plate 400 is made of flame-retardant materials, such as styrene, to prevent the electric heating module 300 from igniting the cover plate 400.

[0031] In some examples, such as Figures 2 to 5 As shown, the ceiling machine also includes a buffer 700, which is located between the second mounting plate section 420 and the mounting area 120. The second mounting plate section 420 separates the fan assembly 500 from the mounting area 120 (at this time, the orthographic projection of the second mounting plate section 420 on the bottom wall of the chassis 100 intersects with the orthographic projection of the peripheral wall of the impeller 520 on the bottom wall of the chassis 100). In this way, the contact between the impeller 520 of the fan assembly 500 and the cover plate 400 is a flexible contact under the buffering effect of the buffer 700 and the insulation component 200. Therefore, the impeller 520 of the fan assembly 500 is not easily broken or damaged when it collides with the cover plate 400.

[0032] Among them, such as Figures 2 to 5 As shown, the second mounting plate segment 420 is fixed to the mounting area 120 by screws. A positioning structure is provided between the mounting area 120 and the second mounting plate segment 420. This positioning structure pre-positions the second mounting plate segment 420 in the mounting area 120, thereby improving the assembly speed of the second mounting plate segment 420 in the mounting area 120. The positioning structure may include positioning posts 810 and positioning holes (or it may include inserts and slots, etc.). This solution has a simple structure and good positioning effect. Alternatively, the buffer 700 may be made of silicone, rubber, or sponge, etc. All of these can achieve the purpose of this application, and their intent does not depart from the design concept of this invention. Therefore, they will not be elaborated further and should all fall within the protection scope of this application.

[0033] In some embodiments, such as Figure 1 and Figure 2As shown, the fan assembly 500 includes a motor 510 and a fan wheel 520. The orthographic projection of the first mounting plate segment 410 on the bottom wall of the chassis 100 is located inside the orthographic projection of the peripheral wall of the fan wheel 520 on the bottom wall of the chassis 100. In this way, the fan wheel 520 of the fan assembly 500 will at most come into contact with the second covering area 210 and the second mounting plate segment 420. Since the contact between the fan wheel 520 of the fan assembly 500 and the second covering area 210 is also a flexible contact, the fan wheel 520 of the fan assembly 500 is not easily broken or damaged when it collides with the cover plate 400 and the second mounting plate segment 420.

[0034] In some embodiments, such as Figures 2 to 5 As shown, the first mounting plate segment 410 is a circular plate segment (or annular plate), and the second mounting plate segment 420 is an arc-shaped plate segment. The inner edge of the arc-shaped plate segment connects to the outer edge of the circular plate segment (or annular plate), and both ends of the arc-shaped plate segment abut against one end of the adjacent hollow area 220 of the second covering area 210, ensuring that the impeller 520 of the fan assembly 500 contacts at most the second covering area 210 and the second mounting plate segment 420, and does not contact the mounting area 120 of the chassis 100. Figure 5 As shown, the buffer 700 is located at the arc-shaped edge of the second mounting plate section 420. Both ends of the buffer 700 abut against one end of the adjacent hollow area 420 of the second covering area 210, so that the anti-condensation effect of the part of the bottom wall of the chassis 100 corresponding to the cover plate 400 and the second covering area 210 is better.

[0035] Among them, such as Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, a positioning structure is provided between the first mounting plate segment 410 and the second covering area 210. By pre-positioning the first mounting plate segment 410 and the second covering area 210, the positioning structure can improve the assembly speed of the second mounting plate segment 420 in the mounting area 120. This can be, for example... Figure 7 As shown, the positioning structure includes a positioning post 810 and a positioning hole 820 (or it can be a positioning structure including inserts and slots, etc.). This solution has a simple structure and good positioning effect.

[0036] In some examples, such as Figure 1 and Figure 2 As shown, the electric heating module 300 is arranged along the edge of the hollow area 220 away from the second covered area 210, which completely eliminates the safety hazard of the electric heating module 300 igniting the insulation foam.

[0037] In some embodiments, such as Figure 2As shown, both the installation area 120 and the hollow area 220 are triangular in shape and have a first edge, a second edge, and a third edge arranged sequentially along the circumference. The second edge b and the third edge c of the hollow area 220 are located on the side of the first edge a of the hollow area 220 away from the second covering area 210. The electric heating module 300 includes two sets, both in a straight line shape, and the two electric heating modules 300 are arranged one-to-one along the second edge b and the third edge c of the hollow area 220. The first covering area 110 and the second covering area 210 are both triangular in shape, and the insulation component 200 also has an annular peripheral wall, which is quadrilateral in shape. This solution requires only one operator (on one side of the production line) to complete the fixed installation of the two electric heating modules 300 in the installation area 120, resulting in lower labor costs. Moreover, this solution also facilitates the disassembly and maintenance of the electric heating modules 300 by after-sales personnel.

[0038] Among them, such as Figure 1 , Figure 2 and Figure 6 As shown, each electric heating module 300 includes two electric heaters 310 and mounting bases 320 located at both ends of the two electric heaters 310. The two electric heaters 310 are fixedly connected to the two mounting bases 320 by four screws. The two mounting bases 320 are fixedly connected to the mounting area 120 by two screws. A positioning structure is provided between the mounting bases 320 and the mounting area 120. The positioning structure can improve the assembly speed of the mounting bases 320 in the mounting area 120 by pre-positioning the mounting bases 320 and the mounting area 120. Alternatively, the positioning structure can include positioning posts 810 and positioning holes (or it can include inserts and slots, etc.). This solution has a simple structure and good positioning effect. Alternatively, the electric heaters 310 can be configured as thermistors.

[0039] In some examples, such as Figure 2 and Figure 4 As shown, the cover plate 400 is provided with a wiring structure 430 and a wire-clamping structure 440. The wire-clamping structure 440 is located between the wiring structure 430 and the motor 510 of the fan assembly 500, and is offset from the wiring direction of the wiring structure 430. This ensures that when the motor cable is pulled, the point of force application is located at the wire-clamping structure 440, preventing the solder joint between the motor cable and the motor 510 from being pulled off. Alternatively, the wiring structure 430 can be configured as a wiring channel, and the wire-clamping structure 440 can be configured as a wire-clamping clip.

[0040] In some examples, such as Figure 1 and Figure 2As shown, the ceiling machine also includes: an open annular heat exchanger 600, the bottom wall of the insulation component 200 has a support area 230, the bottom wall of the chassis 100 has a third covering area 130, the shape of the support area 230 matches the shape of the heat exchanger 600 (such as a closed ring shape or an open ring shape), the second covering area 210 and the hollow area 220 are located inside the support area 230, the support area 230 is placed in the third covering area 130 (in a closed ring shape), the heat exchanger 600 is placed on the side of the support area 230 facing away from the third covering area 130, and the electric heating module 300 is located inside the heat exchanger 600.

[0041] Compared to the insulation component 200 without a bottom wall, this solution increases the airflow of the ceiling unit by approximately 20m³. 3 / h; noise is reduced by about 1dB; and in extreme drop tests, the wind turbine 520 does not crack or break.

[0042] In some examples, such as Figure 2 and Figure 3 As shown, the bottom wall of the chassis 100 is provided with a mounting post 140, which passes through the first mounting plate section 410. The motor 510 is mounted on the mounting post 140 through foot pads. At this time, the foot pads are pressed between the cover plate 300 and the motor. In this way, part of the vibration energy of the fan assembly 500 is transferred to the cover plate 300 through the foot pads and dissipated by the buffer 700 and the second shielding area 210. The other part of the vibration energy is transferred to the chassis through the mounting post 140. Therefore, the vibration and noise generated by the chassis 100 are smaller.

[0043] The air conditioner provided in this application embodiment (not shown in the figure) includes the ceiling-mounted air conditioner described in any of the above embodiments.

[0044] This air conditioner possesses all the advantages of the ceiling-mounted unit provided in any of the above embodiments, and will not be repeated here.

[0045] In summary, the technical solution provided in this application embodiment involves placing the second covering area of ​​the bottom wall of the insulation component within the first covering area of ​​the bottom wall of the chassis. At least a portion of the second mounting plate segment of the cover plate is located within the mounting area from the perforated area. The second covering area isolates the first covering area from the cold air inside the ceiling unit, and the second mounting plate segment also isolates the mounting area from the cold air inside the ceiling unit. This improves the condensation problem on the outer bottom surface of the chassis during cooling operation. Furthermore, the perforated area is opposite to the mounting area, and the electric heating module is located within the mounting area from the perforated area and spaced apart from the insulation component. This eliminates the safety hazard of the electric heating module igniting the insulation foam.
