Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to an embedded air conditioning indoor unit. Background Technology

[0002] Currently, with the rapid development of the air conditioning industry and people's pursuit of a high quality of life, embedded central air conditioning is becoming increasingly popular. The air outlets on the embedded central air conditioning panel on the market are basically four, which makes it difficult to achieve full-circuit air supply and will result in uneven air supply. When cooling, a large amount of cold air will blow vertically downwards, causing a decrease in the physical comfort of users located below the air outlets and resulting in low air supply comfort.

[0003] A related technology includes a four-sided air outlet embedded air conditioner, comprising a panel body, side air outlets, return air outlets, and corner air outlets. The characteristic feature is that a return air outlet is located in the center of the panel body, four side air outlets are located around the perimeter of the panel body, and a corner air outlet is located at each of the four corners of the panel body. A first and second air guide plate are installed in the side air outlets, and a third and fourth air guide plate are installed in the corner air outlets. The combination of the side and corner air outlets achieves circumferential airflow.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] The air volume of the corner air outlet is relatively small, and the air temperature of the outlet differs from that of the side air outlet, resulting in poor temperature uniformity of the airflow and low air supply comfort. In addition, in order to connect the corner air outlet with the air duct, a complex structure needs to be set up inside the air conditioner, which occupies the limited space inside the air conditioner. Summary of the Invention

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides an embedded air conditioner indoor unit to increase the air volume at the corner air outlet, reduce the temperature difference between the airflow at the corner air outlet and the airflow at the main air outlet, improve the uniformity of the airflow temperature, and simplify the internal structure of the embedded air conditioner indoor unit.

[0008] In some embodiments, an embedded air conditioning indoor unit includes: a water collection tray, an upper partition, and corner partitions. The lower side wall of the water collection tray has a main air outlet and corner air outlets; the upper partition covers the upper side of the water collection tray, enclosing an air outlet duct between the upper partition and the water collection tray; the corner partitions are disposed between the corners of the water collection tray and the upper partition, and the inner side of the corner partitions has a drainage channel; wherein the main air outlet is connected to the air duct, and the corner air outlets are connected to the air duct through the drainage channel.

[0009] The embedded air conditioner indoor unit provided in this embodiment can achieve the following technical effects:

[0010] The embedded air conditioner indoor unit utilizes a water collection tray and an upper partition to internally enclose the air outlet duct. A corner partition is installed between the corner of the water collection tray and the corner of the upper partition. The heat exchange airflow inside the duct can directly flow into the main air outlet and be blown out, while the remaining heat exchange airflow can flow into the corner air outlet through the guide channel on the inner side of the corner partition and be blown out. This increases the airflow volume at the corner air outlet, reduces the temperature difference between the airflow at the corner air outlet and the airflow at the main air outlet, and improves the uniformity of the airflow temperature. By utilizing the cooperation of the water collection tray, upper partition, and corner partition inside the embedded air conditioner indoor unit, the airflow in the duct flows smoothly into the corner air outlet and is blown out, simplifying the internal structure of the embedded air conditioner indoor unit.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0036] Combination Figure 1-15As shown, this embodiment of the present disclosure provides an embedded air conditioner indoor unit, including: a water collection tray 100, an upper partition 200, and a corner partition 300. The lower side wall of the water collection tray 100 is provided with a main air outlet 110 and a corner air outlet 120; the upper partition 200 covers the upper side of the water collection tray 100, and encloses an air outlet duct 400 between the upper partition 200 and the water collection tray 100; the corner partition 300 is disposed between the corner of the water collection tray 100 and the corner of the upper partition 200, and the inner side of the corner partition 300 has a drainage channel 310; wherein, the main air outlet 110 is connected to the air duct 400, and the corner air outlet 120 is connected to the air duct 400 through the drainage channel 310.

[0037] In this embodiment, the water tray 100 and upper partition 200 of the embedded air conditioner indoor unit enclose the air outlet duct 400 internally. A corner partition 300 is provided between the corner of the water tray 100 and the corner of the upper partition 200. The heat exchange airflow inside the air outlet 400 can directly flow into the main air outlet 110 and be blown out. The remaining heat exchange airflow can flow into the corner air outlet 120 through the guide channel 310 inside the corner partition 300 and be blown out. This increases the air volume of the corner air outlet 120, reduces the temperature difference between the airflow from the corner air outlet 120 and the airflow from the main air outlet 110, and improves the uniformity of the air outlet temperature. By utilizing the cooperation of the water tray 100, upper partition 200 and corner partition 300 inside the embedded air conditioner indoor unit, the airflow in the air outlet 400 flows smoothly into the corner air outlet 120 and is blown out, simplifying the internal structure of the embedded air conditioner indoor unit.

[0038] Optionally, the drip tray 100 has a rectangular annular structure. A main air outlet 110 is provided on the lower sidewall area corresponding to each side of the drip tray 100, and a corner air outlet 120 is provided at each corner of the lower sidewall of the drip tray 100. This provides the lower sidewall of the drip tray 100 with multiple main air outlets 110 and multiple corner air outlets 120, forming a circumferential air supply and improving the air delivery effect of the embedded air conditioning indoor unit.

[0039] Specifically, the rectangular annular water collection tray 100 has four sides and four corners. Each side has a main air outlet 110 on its lower sidewall, resulting in four main air outlets 110. Each corner also has a corner air outlet 120, resulting in four corner air outlets 120. Each corner air outlet 120 is located between the ends of two adjacent main air outlets 110. This allows the embedded air conditioner indoor unit to achieve circumferential airflow from eight positions, improving the airflow efficiency of the embedded air conditioner. For example, if the positions of the four main air outlets 110 located on the four side areas of the water receiving tray 100 are marked as 12 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock, then the positions of the four corner air outlets 120 located on the four corner areas of the water receiving tray 100 are marked as 1:30, 4:30, 7:30, and 10:30. When air is discharged through these four main air outlets 110 and the four corner air outlets 120, air can be discharged from eight positions: 12 o'clock, 1:30, 3 o'clock, 4:30, 6 o'clock, 7:30, 9 o'clock, and 10:30.

[0040] Combination Figure 4-9 As shown, in some embodiments, the upper partition 200 is a rectangular ring structure, and the air duct 400 enclosed by the water receiving tray 100 and the upper partition 200 is also a rectangular ring channel. A heat exchanger 420 is provided in the air inlet area 410 of the air duct 400, and the heat exchanger 420 is a rectangular ring coil structure. Thus, since four main air outlets 110 and four corner air outlets 120 are sequentially arranged on the lower side wall of the water receiving tray 100, forming a full-circumference air outlet area, an upper partition 200 with a rectangular annular structure adapted to the shape of the water receiving tray 100 is provided. The upper partition 200 and the water receiving tray 100 cooperate to enclose a rectangular annular air duct 400, which facilitates the airflow in the air duct 400 to flow evenly into the four main air outlets 110 and the four corner air outlets 120 and blow out, ensuring the air volume. Moreover, in order to ensure the temperature uniformity of the blown airflow, a heat exchanger 420 with a rectangular annular coil structure is provided in the air duct 400, so that the return airflow can pass through the heat exchanger 420 and flow into the air duct 400, improving the heat exchange effect of the return airflow and making the temperature uniformity of the airflow blown out through the main air outlets 110 and the corner air outlets 120 even higher.

[0041] Combination Figure 5 and Figure 6The upper partition 200 includes a vertical annular portion 210 and a horizontal annular portion 220. The lower end of the vertical annular portion 210 is connected to the water receiving tray 100; the horizontal annular portion 220 is disposed on the inner ring side of the vertical annular portion 210, and the outer ring end of the horizontal annular portion 220 is connected to the upper end of the vertical annular portion 210. The lower sidewall of the horizontal annular portion 220 and the upper sidewall of the water receiving tray 100 define the air inlet area 410. Thus, the upper partition 200, composed of a vertical annular portion 210 and a horizontal annular portion 220, has the horizontal annular portion 220 extending inward along the inner ring side of the vertical annular portion 210. The lower side wall of the horizontal annular portion 220 and the upper side wall of the water receiving tray 100 define the air inlet area 410 of the air duct 400. When the return air flow from the return air inlet 530 flows into the air duct 400, it needs to pass through the air inlet area 410. Therefore, the heat exchanger 420 is installed in the air inlet area 410 so that the air flow in the air duct 400 can be evenly exchanged with the heat exchanger 420. Moreover, the air inlet area 410 is defined between the horizontal annular portion 220 and the upper side wall of the water receiving tray 100, which facilitates the installation of the heat exchanger 420 in the air inlet area 410 and keeps the installed heat exchanger 420 in a vertical position, which facilitates the collection of condensate from the heat exchanger 420.

[0042] Combination Figure 7 and Figure 8 As shown, the upper side wall of the water receiving tray 100 is provided with a heat exchanger mounting groove 130, and the lower end of the heat exchanger 420 is embedded in the heat exchanger mounting groove 130 for installation. In this way, the heat exchanger 420 is installed and fixed by using the heat exchanger mounting groove 130 provided on the upper side wall of the water receiving tray 100, which makes the heat exchanger 420 installed in the air inlet area 410 more stable. The heat exchanger mounting groove 130 can also be used to collect the condensate of the heat exchanger 420. Through the structure of the water receiving tray 100 itself, the heat exchanger 420 is supported and installed at the same time as collecting condensate, eliminating the need for auxiliary structures for installing the heat exchanger 420 and reducing the space occupied inside the shell 500.

[0043] Specifically, the heat exchanger mounting groove 130 is a rectangular annular groove located on the upper side wall of the water receiving pan 100. This allows for better installation of the heat exchanger 420 with a rectangular annular coil structure.

[0044] Combination Figure 9As shown, a water storage tank 131 is provided at the bottom of the heat exchanger mounting groove 130, and the lower end of the heat exchanger 420 is higher than the top of the water storage tank 131 in the vertical direction. Since the heat exchanger mounting groove 130 is located on the upper side wall of the water receiving pan 100, it can not only install the heat exchanger 420 but also collect the condensate generated by the heat exchanger 420. However, when the condensate flows into the heat exchanger mounting groove 130, the bottom of the heat exchanger 420 will be immersed in the condensate, affecting the heat exchange effect. Therefore, a water storage tank 131 is provided at the bottom of the heat exchanger mounting groove 130, and the lower end of the heat exchanger 420 is higher than the top of the water storage tank 131. The condensate collected in the heat exchanger mounting groove 130 flows into the water storage tank 131 under gravity for storage, preventing the condensate from contacting the lower end of the heat exchanger 420. This ensures the heat exchange effect of the heat exchanger 420 while collecting the condensate.

[0045] Optionally, a drain pipe is connected to the bottom of the water storage tank 131, and the drain pipe connects to the outside of the housing 500. In this way, the condensate stored in the water storage tank 131 can be discharged in a timely manner using the drain pipe.

[0046] Combination Figure 10 As shown, in some embodiments, the embedded air conditioner indoor unit further includes a housing 500. A water tray 100 and an upper partition 200 are both disposed inside the housing 500. A main air outlet 510 is provided on the lower side wall of the housing 500 at a position corresponding to the main air outlet 110, and a corner air outlet 520 is provided at a position corresponding to the corner air outlet 120. In this way, the water tray 100 and the upper partition 200 are both installed inside the housing 500, and the lower side wall of the housing 500 is provided with a main air outlet 510 corresponding to the main air outlet 110 and a corner air outlet 520 corresponding to the corner air outlet 120. After the water tray 100 and the upper partition 200 are installed, the airflow in the main air outlet 110 and the corner air outlet 120 can be smoothly blown into the room. The housing 500 facilitates the installation of the embedded air conditioner indoor unit, and the housing 500 protects the internal structure such as the water tray 100, the upper partition 200 and the corner partition 300.

[0047] Optionally, the lower sidewall of the housing 500 has a return air inlet 530 in the middle region. The return air inlet 530 is located inside the circumferential area formed by the four main air outlets 110 and the four corner air outlets 120. The water collection tray 100 is disposed inside the lower sidewall of the housing 500, and the inner ring area of ​​the water collection tray 100 corresponds to the return air inlet 530. In this way, the housing 500 supports the water collection tray 100 and the upper partition 200. The return airflow in the room flows in through the return air inlet 530 and passes through the inner ring area of ​​the water collection tray 100 to enter the interior of the housing 500.

[0048] Optionally, the shape of the main air outlet 510 is adapted to the shape of the main air outlet 110, and the shape of the corner air outlet 520 is adapted to the shape of the corner air outlet 120. This allows the airflow from the main air outlet 110 to pass more smoothly through the main air outlet 510, and the airflow from the corner air outlet 120 to pass more smoothly through the corner air outlet 520, preventing the housing 500 from obstructing the airflow and reducing the loss of airflow pressure.

[0049] Combination Figure 11 , Figure 12 and Figure 13 As shown, in some embodiments, the corner portions of the upper partition 200 and the water receiving pan 100 are the piping corner portion and the connecting corner portion, respectively. The piping corner portion of the upper partition 200 and the piping corner portion of the water receiving pan 100 together enclose the piping installation area 230, and the piping end of the heat exchanger 420 is located within the piping installation area 230. Since the heat exchanger 420 needs to be connected to the outdoor unit and compressor via piping at the inlet and outlet of its refrigerant, and the heat exchanger 420 has a rectangular annular coil structure with the piping end of the heat exchanger 420 located in the corner area, the corner of the upper partition 200 and the water receiving pan 100 is divided into a piping corner and a connecting corner. The piping corner of the upper partition 200 and the piping corner of the water receiving pan 100 are used to define the piping installation area 230. When installing the heat exchanger 420, the piping end of the heat exchanger 420 is installed in the piping installation area 230, which facilitates the connection of the piping end of the heat exchanger 420 to the outside. This facilitates the piping connection of the heat exchanger 420 without affecting the air outlet 120 at the corner.

[0050] Optionally, the corner partition 300 includes a piping partition 320 and a connecting partition 330. The piping partition 320 is disposed between the piping corner of the water receiving tray 100 and the piping corner of the upper partition 200; the connecting partition 330 is disposed between the connecting corner of the water receiving tray 100 and the connecting corner of the upper partition 200. Thus, since the corners of the water receiving pan 100 and the upper partition 200 are divided into a piping corner and a connecting corner, the corner partition 300 is also divided into a piping partition 320 and a connecting partition 330. The piping partition 320 is installed between the piping corner of the water receiving pan 100 and the piping corner of the upper partition 200. The airflow within the duct 400 is guided to the corner air outlet 120 via the flow channel 310 inside the piping partition 320, thus avoiding interference with the piping connections of the heat exchanger 420. It can ensure that the airflow of the air duct 400 can flow smoothly into the corner air outlet 120, and improve the air output of the corner air outlet 120 corresponding to the corner of the water receiving tray 100. The connecting partition plate 330 is installed between the connecting corner of the water receiving tray 100 and the connecting corner of the upper partition plate 200. The airflow in the air duct 400 is guided to the corner air outlet 120 corresponding to the connecting corner by the flow channel 310 inside the connecting partition plate 330, so as to provide sufficient air volume for multiple corner air outlets 120.

[0051] like Figure 11 As shown, region A is the corner of the piping between the water receiving tray 100 and the upper partition 200, and region B is the connecting corner between the water receiving tray 100 and the upper partition 200.

[0052] like Figure 12 As shown, region A1 is the corner of the piping of the water receiving pan 100, and region B1 is the connecting corner of the water receiving pan 100.

[0053] Specifically, both the water receiving tray 100 and the upper partition 200 have one piping corner and three connecting corners. When the water receiving tray 100 and the upper partition 200 are assembled, one piping corner of the water receiving tray 100 fits into one piping corner of the upper partition 200, and the other three connecting corners of the water receiving tray 100 fit into the other three connecting corners of the upper partition 200. The corner partition 300 includes one piping partition 320 and three connecting partitions 330. One piping partition 320 is disposed between the piping corner of the water receiving tray 100 and the piping corner of the upper partition 200, and the other three connecting partitions 330 are disposed between the three connecting corners of the water receiving tray 100 and the three connecting corners of the upper partition 200, with one connecting partition 330 corresponding to each connecting corner.

[0054] Understandably, the pipe corner can refer to the pipe corner of the water pan 100 or the pipe corner of the upper partition 200, or it can refer to the pipe corner of the water pan 100 and the upper partition 200.

[0055] Optionally, the drainage channel 310 on the inner side of the corner partition 300 is divided into a funnel-shaped drainage channel 311 and a through-type drainage channel 312.

[0056] Combination Figure 13 As shown, the inner side of the piping partition 320 has a funnel-shaped drainage channel 311, and the inner side of the connecting partition 330 has a through-shaped drainage channel 312. The corner air outlet 120 corresponding to the corner of the water receiving tray 100 is connected to the air duct 400 through the funnel-shaped drainage channel 311 on the inner side of the piping partition 320. The corner air outlet 120 corresponding to the corner of the connecting partition 100 is connected to the air duct 400 through the through-shaped drainage channel 312 on the inner side of the connecting partition 330. Thus, since the pipe installation area 230 is located at the corner of the water receiving tray 100 and the upper partition 200, the structure of the pipe corner is different from that of the connecting corner. The drainage channel 310 located inside the partition 320 of the pipe area at the pipe corner is a trumpet-shaped drainage channel 311, which can be adapted to the drainage of the corner air outlet 120 corresponding to the pipe corner. The trumpet-shaped drainage channel 311 is used to better introduce the airflow in the duct 400 into the corner air outlet 120 corresponding to the pipe corner. The drainage channel 310 located inside the connecting partition 330 of the connecting corner is a through-type drainage channel 312, which can be adapted to the drainage of the corner air outlet 120 corresponding to the connecting corner. The through-type drainage channel 312 is used to better introduce the airflow in the duct 400 into the corner air outlet 120 corresponding to the connecting corner and blow it out, ensuring the airflow of the four corner air outlets 120.

[0057] Specifically, the piping partition 320 has an L-shaped structure. One end of the piping partition 320 has a horn-shaped protrusion 321. The inner side of the horn-shaped protrusion 321 has a horn-shaped drainage channel 310. One end of the horn-shaped drainage channel 310 is connected to the air duct 400, and the other end is connected to the corner air outlet 120 of the corresponding piping partition 320. The other end of the piping partition 320 has a plate-like structure and is connected to the side wall of the upper partition 200. In this way, an L-shaped piping partition 320 is set at the corner of the piping between the water receiving tray 100 and the upper partition 200. One end of the piping partition 320 has a trumpet-shaped protrusion 321, which is connected to the air duct 400 at the corner by the trumpet-shaped drainage channel 310 inside the trumpet-shaped protrusion 321. The other end is a plate-shaped structure, which makes room for the piping installation area 230. While ensuring the air outlet 120 at the corner of the piping partition 320, it also facilitates the installation of the heat exchanger 420 piping.

[0058] Specifically, the connecting partition 330 is also an L-shaped plate structure. The connecting partition 330 has two through-shaped drainage channels 312 symmetrically distributed at their corners. Both through-shaped drainage channels 312 are connected to the corner air outlets 120 corresponding to the connecting partition 330. Since there is no need to consider the installation of the heat exchanger 420 piping at the corner of the connecting duct 400, an L-shaped plate-like connecting partition 330 is set at the corner of the connecting water tray 100 and the upper partition 200. Two through-type flow channels 312 are symmetrically arranged with the corner of the connecting partition 330 as the center, so that the airflow on both sides of the corner of the duct 400 can flow into the corner air outlet 120 corresponding to the connecting partition 330 through the through-type flow channels 312 and be blown out. This ensures the airflow of the corner air outlet 120 and makes reasonable use of the heat at the corner of the heat exchanger 420, thereby improving the overall heat exchange uniformity of the heat exchanger 420.

[0059] Combination Figure 14 and Figure 15 As shown, in some embodiments, the water receiving tray 100 includes a tray body 101 and a lower partition 102. The tray body 101 has a groove 103 on its side; the lower partition 102 is embedded in the groove 103, and the side wall of the lower partition 102 opposite to the tray body 101 defines a flow channel 104. The upper port of the flow channel 104 communicates with the air duct 400, and the main air outlet 110 is the lower port of the flow channel 104. In this way, the water receiving tray 100 is divided into a tray body 101 and a lower partition 102. A groove 103 is provided on the side of the tray body 101, and the lower partition 102 is embedded in the groove 103. The flow channel 104 is defined by the side wall of the lower partition 102 opposite to the tray body 101. The lower end of the flow channel 104 is the main air outlet 110, and the upper end of the flow channel 104 is connected to the air duct 400. The airflow in the air duct 400 flows directly into the flow channel 104 and is blown out through the main air outlet 110. The cooperation structure between the lower partition 102 and the tray body 101 facilitates the disassembly and maintenance of the flow channel 104.

[0060] Specifically, the four sides of the plate body 101 are provided with grooves 103, and there are four lower partitions 102. Each lower partition 102 is embedded in a corresponding groove 103. The plate body 101 and the embedded lower partitions 102 together form a rectangular ring structure water receiving plate 100.

[0061] Optionally, a guide vane 105 is provided inside the main air outlet 110, and an arc-shaped guide protrusion 106 is provided on the side wall of the lower partition 102 facing the flow channel 104. In this way, the airflow in the flow channel 104 is guided by the guide vane 105, and the arc-shaped guide protrusion 106 on the side wall of the lower partition 102 facing the flow channel 104 can guide part of the airflow in the flow channel 104 to the leeward side of the guide vane 105, thereby changing the dew point temperature of the leeward side area of ​​the guide vane 105, so that the temperature of the guide vane 105 itself is higher than the dew point temperature of the leeward side area of ​​the guide vane 105, thus reducing the generation of condensation on the leeward side of the guide vane 105.

[0062] Optionally, when the air guide plate 105 is open, the windward side of the air guide plate 105 is arranged facing the side wall of the lower partition 102, there is an air outlet gap between the windward side of the air guide plate 105 and the side wall of the lower partition 102, and there is a flow guiding gap between the leeward side of the air guide plate 105 and the side wall of the disc 101. In this way, when the air guide plate 105 is opened, the windward side of the air guide plate 105 faces the side wall of the lower partition 102. Part of the airflow in the flow channel 104 flows into the indoor environment along the air outlet gap between the windward side of the air guide plate 105 and the side wall of the lower partition 102. The remaining airflow flows to the leeward side of the air guide plate 105 along the guide gap between the leeward side of the air guide plate 105 and the side wall of the plate 101, cooling the leeward area of ​​the air guide plate 105. This makes the dew point temperature of the leeward area of ​​the air guide plate 105 lower than the temperature of the air guide plate 105, thereby reducing the generation of condensation on the air guide plate 105. The airflow in the flow channel 104 can be blown out evenly through the guide gap and the air outlet gap, reducing airflow loss. While reducing condensation on the air guide plate 105, the cooling effect of the indoor environment is maintained.

[0063] Understandably, the windward and leeward sides of the air guide plate 105 refer to the side of the air guide plate 105 facing the flow channel 104 when the air guide plate 105 is closed, which is the windward side of the air guide plate 105, and the side of the air guide plate 105 away from the flow channel 104, which is the leeward side of the air guide plate 105.

[0064] Optionally, the portion of the leeward side of the air guide plate 105 facing the disk 101 has an arc-shaped guide surface. This makes the leeward side of the air guide plate 105 an arc-shaped structure. When the air guide plate 105 is open, the arc-shaped guide surface facing the disk 101 and the side wall of the disk 101 work together to guide the airflow, allowing the airflow to flow better along the leeward side of the air guide plate 105 and changing the dew point temperature of the leeward area of ​​the air guide plate 105.

[0065] Understandably, when the air guide plate 105 is open, the leeward side of the air guide plate 105 and the side wall of the disc 101 define a flow guide gap, and the arc-shaped flow guide surface is part of the leeward side of the air guide plate 105, so the arc-shaped flow guide surface can be regarded as part of the inner wall of the flow guide gap.

[0066] Optionally, both the upper partition 200 and the lower partition 102 are made of foam material. In this way, the lower partition 102 and the upper partition 200 made of foam material are lighter, which can reduce the overall weight of the embedded air conditioner indoor unit, making it easier to install in the ceiling. Moreover, the foam material has good thermal insulation properties, which can better insulate and seal the air duct 400 and the flow channel 104.

[0067] Combination Figure 15 As shown, the upper end of the lower partition 102 is provided with a first stepped fastening seat 107, and the lower end of the upper partition 200 is provided with a second stepped fastening seat 240. The first stepped fastening seat 107 and the second stepped fastening seat 240 are fastened together so that the upper end of the lower partition 102 is fastened and connected to the lower end of the upper partition 200. In this way, through the cooperation of the first stepped fastening seat 107 and the second stepped fastening seat 240, the upper end of the lower partition 102 and the lower end of the upper partition 200 are more tightly fastened together. At the fastening connection between the lower partition 102 and the upper partition 200, two planes and one inclined plane are formed to isolate the partition, reducing the leakage of airflow in the flow channel 104. This prevents the leaked airflow from blowing directly onto the shell 500 and causing condensation on the outer wall of the shell 500. Moreover, the lower partition 102 and the upper partition 200 are fastened together by the first stepped fastening seat 107 and the second stepped fastening seat 240, which can reduce the friction and collision between the lower partition 102 and the upper partition 200 during assembly, and reduce the phenomenon of particle shedding between the lower partition 102 and the upper partition 200 made of foam material.
