DETAILED DESCRIPTION

[0029] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0030] The ceiling machine provided by the related technology has the phenomenon of condensed water dripping out of the air outlet during operation in a high temperature (temperature not less than 35 degrees) and high humidity (humidity not less than 80%) environment. However, when the ceiling machine is operated in an environment with a temperature not higher than 32 degrees and a humidity not higher than 60%, there is no phenomenon of condensed water dripping out of the air outlet.

[0031] The analysis and research found that: the side of the water tray facing the heat exchanger is convexly provided with a first annular wall and a second annular wall, the first annular wall is located on the inner side of the second annular wall, a water receiving groove is formed between the first annular wall and the second annular wall, an air outlet is formed between the second annular wall and the peripheral wall of the chassis, and one end of the heat exchanger adjacent to the water tray is located in the water receiving groove. During the operation of the ceiling machine in a high temperature (temperature not less than 35 degrees) and high humidity (humidity not less than 80%) environment, the condensed water flowing down from the heat exchanger falls into the water receiving groove. In this process, a lot of condensed water is generated, and a large amount of condensed water will directly contact the second annular wall, causing the temperature of the second annular wall to drop rapidly and be lower than the condensation temperature, which will cause condensation on the side of the second annular wall facing away from the first annular wall. This is also the reason why condensed water drips out from the air outlet during the operation of the ceiling machine in a high temperature (temperature not less than 35 degrees) and high humidity (humidity not less than 80%) environment.

[0032] The ceiling machine provided in the embodiment of the present application is as follows: Figure 1As shown, it includes a bottom plate 100, a heat exchanger 200 and a water receiving tray 300. The heat exchanger 200 is arranged in the bottom plate 100, and the water receiving tray 300 is arranged at the opening of the bottom plate 100. Figures 1 to 4 As shown, the water receiving tray 300 includes: an annular body, which is arranged at the opening of the bottom plate 100, and a first annular wall 320, a second annular wall 330 and a third annular wall 340 are provided on the side of the bottom wall of the bottom plate 100, the first annular wall 320 is located on the inner side of the second annular wall 330, the third annular wall 340 is located between the first annular wall 320 and the second annular wall 330, a water receiving groove 350 is formed between the first annular wall 320 and the third annular wall 340, an isolation groove 360 ​​is formed between the second annular wall 330 and the third annular wall 340, and the third annular wall 340 is configured to prevent condensed water in the water receiving groove 350 from flowing to the isolation groove 360, and an end of the heat exchanger 200 adjacent to the body is located in the water receiving groove 350.

[0033] When the ceiling machine is operating in a high temperature (temperature not lower than 35 degrees) and high humidity (humidity not lower than 80%) environment, a large amount of condensed water in the water receiving groove 350 is in direct contact with the third annular wall 340, which will cause the temperature of the third annular wall 340 to quickly drop below the condensation temperature, causing condensation to occur on the side of the third annular wall 340 that faces away from the first annular wall 320. However, this amount of condensed water (i.e., condensed water) is relatively small and falls into the isolation groove 360, which will not cause the temperature of the second annular wall 330 to drop below the condensation temperature. Therefore, condensation will not occur on the side of the second annular wall 330 that faces away from the third annular wall 340, so the ceiling machine will not drip condensed water from the air outlet 500.

[0034] Figure 1 In the figure, reference numeral 710 is a panel (the periphery of panel 710 has four air outlets for air outlet, and the middle of the panel has one air outlet for air inlet), reference numeral 720 is an air guide ring, reference numeral 730 is an electric control box, reference numeral 740 is a motor, and reference numeral 750 is a wind wheel.

[0035] In some examples, such as Figures 1 to 4 As shown, the body, the first annular wall 320 and the second annular wall 330 are all in a closed ring shape, the third annular wall 340 is in an open ring shape, and the area between the first annular wall 320 and the second annular wall 330 at the opening of the third annular wall 340 on the body forms a collecting area 370, and the water receiving groove 350 and the isolation groove 360 ​​are both connected to the collecting area 370. The collecting area 370 is equipped with a water pump 760, and the condensed water flowing from the water receiving groove 350 and the isolation groove 360 ​​to the collecting area 370 is discharged through the water pump 760.

[0036] In some embodiments, Figure 3As shown, the bottom wall of the collecting area 370 is 3 mm to 6 mm lower than the bottom wall of the water receiving trough 350 to avoid water accumulation inside the water receiving trough 350; Figure 3 As shown, the bottom wall of the collecting area 370 is 3 mm to 6 mm lower than the bottom wall of the isolation groove 360 ​​to avoid water accumulation inside the isolation groove 360; Figure 3 and Figure 4 As shown, the width of the isolation groove 360 ​​is not less than 5 mm, so that the temperature of the second annular wall 330 will not drop to the condensation temperature; Figure 3 As shown, the height of the second annular wall 330 is not less than 30 mm, and the height of the third annular wall 340 is not greater than (e.g., equal to or slightly less than) the height of the second annular wall 330. In this way, the volumes of the water receiving groove 350 and the isolation groove 360 ​​are relatively large, and there will be no problem of water overflowing from the water receiving tray 300.

[0037] In some examples, such as Figures 5 to 7 As shown, the ceiling machine also includes: a second thermal insulation component 400 having a bottom wall and a surrounding wall, the second thermal insulation component 400 is arranged in the chassis 100, the bottom wall of the second thermal insulation component 400 is abutted against the bottom wall of the chassis 100, the surrounding wall of the second thermal insulation component 400 is abutted against the surrounding wall of the chassis 100, the heat exchanger 200 is located on the inner side of the area enclosed by the second thermal insulation component 400, and the surrounding wall of the second thermal insulation component 400 is not lower than the surrounding wall of the chassis 100, so as to prevent the blown cold air from contacting the surrounding wall of the chassis 100. This solution can better avoid condensation on the surrounding wall of the chassis 100.

[0038] Among them, the peripheral wall of the second thermal insulation component 400 is not lower than the peripheral wall of the chassis 100: it can be that the opening end of the peripheral wall of the second thermal insulation component 400 is flush with the opening end of the peripheral wall of the chassis 100; or it can be that the opening end of the peripheral wall of the second thermal insulation component 400 is higher than the opening end of the peripheral wall of the chassis 100, such as the opening end of the peripheral wall of the second thermal insulation component 400 is 1mm to 3mm higher than the opening end of the peripheral wall of the chassis 100; the above can all achieve the purpose of the present application, and its purpose does not deviate from the design concept of the present utility model, and will not be repeated here, and should all fall within the protection scope of the present application.

[0039] In some embodiments, Figures 2 to 4 As shown, the body is quasi-square, and mounting portions 380 are formed at the corners of the outer circumference of the body and protrude outward along the radial direction of the body. A portion of the collecting area 370 and a portion of the second annular wall 330 are simultaneously located on one of the mounting portions 380 (the mounting portion 380 is the first mounting portion 381), and the other mounting portions 380 are all located outside the area surrounded by the second annular wall 330. Figures 5 to 7As shown, mounting grooves 410 are provided at the corners of the inner circumferential surface of the second thermal insulation component 400. The mounting grooves 410 correspond to the mounting portions 380 one by one. The side of the mounting grooves 410 facing away from the bottom wall of the second thermal insulation component 400 is connected. A plurality of mounting portions 380 are provided in the plurality of mounting grooves 410 one by one at the radial outer end of the main body. The groove walls of the mounting grooves 410 separate the mounting portions 380 from the circumferential wall of the chassis 100. A plurality of air outlets 500 are formed between the main body and the circumferential wall of the second thermal insulation component 400. The plurality of air outlets 500 are located one by one between adjacent mounting portions 380. In this scheme, the mounting portions 380 will not destroy the thermal insulation structure of the corners of the circumferential wall of the second thermal insulation component 400 at the corners of the circumferential wall of the chassis 100. The second thermal insulation component 400 better ensures the thermal insulation effect at the corners of the circumferential wall of the chassis 100, and completely eliminates the possibility of condensation at the corners of the circumferential wall of the chassis 100. Among them, Figures 4 to 7 As shown, the mounting groove 410 that cooperates with the first mounting portion 381 is the first mounting groove 411, and only the first mounting groove 411 and the area on the peripheral wall of the chassis 100 corresponding to the first mounting groove 411 are set to pass through radially outward of the chassis 100, and the other mounting grooves 410 are closed radially outward of the chassis 100 (that is, the other mounting grooves 410 have a closed groove bottom wall, and the groove bottom wall is the end wall of the mounting groove 410 opposite to the groove opening of the mounting groove 410).

[0040] In some examples, such as Figures 2 to 4 As shown, the main body includes: a closed annular disk body 311, and a first annular wall 320, a second annular wall 330 and a third annular wall 340 are provided on the side of the disk body 311 facing the bottom wall of the second thermal insulation member 400; a closed annular cover body 312, and the cover body 312 is arranged on the other side of the disk body 311 (the other side is the side of the disk body 311 facing away from the bottom wall of the second thermal insulation member 400); and a closed annular first thermal insulation member 313, and the first thermal insulation member 313 is arranged between the disk body 311 and the cover body 312, and the first thermal insulation member 313 isolates the disk body 311 and the cover body 312 to prevent condensation on the cover body 312.

[0041] The ceiling machine provided in this application has a better overall anti-condensation effect.

[0042] In some embodiments, the first thermal insulation component 313 is made of thermal insulation cotton, and the second thermal insulation component 400 is made of foam. Both the thermal insulation cotton and the foam have the advantages of good thermal insulation effect and low manufacturing cost.

[0043] In some embodiments, the tray body 311 and the cover body 312 are both injection molded parts made of plastic material, which have the advantages of mature technology and low production cost. The thickness of the mounting portion 380 is 3mm to 4mm, so that the mounting portion 380 has good strength and is not easily damaged.

[0044] In some examples, such as Figure 2As shown, the inner edge of the cover body 312 is provided with a first snap-fitting portion 610, and the outer edge is provided with a second snap-fitting portion 630, and the disk body 311 is provided with a first snap-fitting portion 620 and a second snap-fitting portion 640. The first snap-fitting portion 610 is snap-fitted to the first snap-fitting portion 620, and the second snap-fitting portion 630 is snap-fitted to the second snap-fitting portion 640, so that the cover body 312 and the disk body 311 are assembled together. This solution has a simple structure and is easy to implement.

[0045] Of course, the purpose of this application can also be achieved by assembling the cover body 312 and the disk body 311 together by screws, etc., and its purpose does not deviate from the design concept of the utility model and will not be repeated here, and it should also fall within the scope of protection of this application.

[0046] The air conditioner (not shown in the figure) provided in the embodiment of the present application includes the ceiling air conditioner described in any of the above embodiments.

[0047] This air conditioner has all the advantages of the ceiling air conditioner provided by any of the above embodiments, which will not be described in detail here.

When the ceiling machine is operating in a high temperature (temperature not lower than 35 degrees) and high humidity (humidity not lower than 80%) environment, a large amount of condensed water in the water receiving groove is in direct contact with the third annular wall, which will cause the temperature of the third annular wall to quickly drop below the condensation temperature, causing condensation on the side of the third annular wall facing away from the first annular wall. However, this part of condensed water (i.e., condensed water) is relatively small and falls into the isolation groove, which will not make the temperature of the second annular wall lower than the condensation temperature. Therefore, condensation will not occur on the side of the second annular wall facing away from the third annular wall, so the ceiling machine will not drip condensed water from the air outlet.
