Description

Technical Field

[0001] This disclosure relates to the field of air conditioning structural design, and in particular to a duct air conditioner and its drip tray, and an air conditioning system. Background Technology

[0002] Ductless air conditioners, also known as concealed air duct systems, are a type of air conditioning system that uses concealed air ducts. They are inexpensive to manufacture, easy to maintain, and well-suited to the air conditioning habits of many Chinese consumers, making them widely used.

[0003] Currently, for ducted air conditioners with downflow vents, the airflow involves an angle change when it flows out of the downflow vent. External airflow can easily enter from the side wall on the side where the airflow angle changes, causing condensation to form on that side. When there is a lot of condensation, it will drip onto the ceiling, causing abnormal noise, corroding the ceiling, and affecting the user experience. Utility Model Content

[0020] A second aspect of this disclosure provides a duct system, comprising:

[0021] The casing has a bottom air outlet;

[0023] A heat exchanger, positioned upstream of the lower air outlet, along the air outlet direction of the fan; and

[0024] The water collection tray according to the first aspect of this disclosure has its width direction aligned with the width direction of the housing. The tray is disposed below the heat exchanger to collect condensate generated by the heat exchanger of the ducted air conditioner. At least a portion of the air guide surface of the water collection tray constitutes a side surface of the lower air outlet located on one side of the housing in the width direction.

[0025] In some embodiments of the ducted air conditioner, the projection of the edge of the heat exchanger near the lower air outlet along the height direction of the casing is located inside the tray. Along the width direction of the casing, the distance L between the edge of the water receiving tray air guide surface connected to the tray and the edge of the heat exchanger near the lower air outlet is 0-20mm.

[0026] In some embodiments of the ducted air conditioning system, the distance L is 5 to 15 mm.

[0068] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0069] refer to Figures 1 to 5 The embodiments of this disclosure provide a duct air conditioner and its drip tray, and an air conditioning system.

[0070] The water receiving tray of the duct air conditioner provided in the embodiments of this disclosure includes a tray body 10 and a first air guide section 11.

[0071] The tray 10 is configured to collect condensate generated by the heat exchanger 4 of the duct air conditioner. A first air guide 11 is connected to one side of the tray 10 along the width direction of the water receiving tray 1. The first air guide 11 has a water receiving tray air guide surface, which is configured to guide the airflow direction of the lower air outlet 21 of the duct air conditioner. The water receiving tray air guide surface includes a first air guide section 111 disposed at one end away from the tray 10 along its own extension direction. In a cross section perpendicular to the length direction of the water receiving tray 1, along the width direction of the water receiving tray 1, from one end near the tray 10 to one end away from the tray 10, the first air guide section 111 is inclined toward the bottom end of the water receiving tray 1.

[0072] refer to Figure 1 and Figure 3 In related technologies, for ducted air conditioners with a down-flow air outlet 21, when air needs to be supplied for cooling through the down-flow air outlet 21, the airflow blown out by the fan 3 of the ducted air conditioner passes through the heat exchanger 4, is cooled by the refrigerant therein, and produces condensate. The water collection tray 1 is set below the heat exchanger 4 to collect the condensate produced by the heat exchanger 4. At the side wall of the water collection tray 1 along the width direction of the ducted air conditioner, close to the down-flow air outlet 21, the airflow direction changes and flows towards the down-flow air outlet 21.

[0073] After the airflow changes direction, it will not flow entirely along the height direction of the duct unit, but will flow at a certain angle to the height direction. Figure 3 The area between the slanted dotted line and the air guide surface of the water tray 1 has a blind spot for the lower air outlet 21. When the duct unit is cooling, the airflow with a higher outside temperature may come into contact with the water tray with a lower temperature through the blind spot and condensation will be generated on the outer wall of the water tray.

[0074] In the water receiving tray provided in the embodiments of this disclosure, a first air guide section 111 is provided on the air guide surface of the water receiving tray. The air guide surface of the water receiving tray is located at the position of the lower air outlet 21 of the air duct machine and can form the side of the lower air outlet 21 located on one side of the width direction of the housing 2. The setting position and extension direction of the first air guide section 111 can be roughly in line with the direction of airflow from downward flow, so that the airflow delivered from the lower air outlet 21 flows along the wall. Therefore, this setting method of the water receiving tray 1 is beneficial to reduce the air supply blind zone at the position of the lower air outlet 21, thereby reducing the risk of the airflow with a higher external temperature entering the air supply blind zone and coming into contact with the water receiving tray with a lower temperature.

[0075] Therefore, by adopting the water collection tray provided in the embodiments of this disclosure, the problem of condensation at the lower air outlet of the duct air conditioner can be improved.

[0076] In some embodiments of the water receiving tray, reference Figure 2 , Figure 4 and Figure 5On a cross section perpendicular to the length of the water receiving tray 1, the angle θ between the first air guide section 111 and the height direction of the water receiving tray is 5° to 35°.

[0077] Based on the range of the included angle θ in this embodiment, the airflow of the lower air outlet 21 can have a better wall-mounted conveying effect at the location of the first air guide section 111.

[0078] In some embodiments, the included angle θ in the water receiving tray is 10° to 25°.

[0079] Based on the range of the included angle θ in this embodiment, on the one hand, the included angle θ is not too small, which is sufficient to maintain the effect of airflow being conveyed along the wall in the first guide section 111; on the other hand, the included angle θ is not too large, which can reduce the impact on the air outlet area of ​​the lower air outlet 21.

[0080] In some embodiments of the water receiving tray, the air guiding surface of the water receiving tray includes a second air guiding section 112. The second air guiding section 112 is disposed at the end of the air guiding surface of the water receiving tray that is connected to the tray body 10. On a cross section perpendicular to the length direction of the water receiving tray 1, along the width direction of the water receiving tray 1, from the end near the tray body 10 to the end away from the tray body 10, the second air guiding section 112 is inclined toward the bottom end of the water receiving tray 1 or extends along the width direction of the water receiving tray 1.

[0081] In this embodiment, the second air guide section 112 is inclined toward the bottom of the water receiving tray 1 or extends along the width direction of the water receiving tray 1. The end of the water receiving tray air guide surface connected to the tray body 10 is the highest point of the water receiving tray 1 along its own height direction. Considering that the end of the water receiving tray air guide surface connected to the tray body 10 is set at the lower side of the heat exchanger 4, this setting can guide the airflow through the heat exchanger 4, so that the airflow can be conveyed along the extension direction of the water receiving tray air guide surface.

[0082] In some embodiments of the water receiving tray, reference Figure 2 , Figure 4 and Figure 5 The inner surface of the plate 10 includes a water receiving surface 101 adjacent to the second air guide section 112. In a cross section perpendicular to the length direction of the water receiving plate 1, the angle α between the second air guide section 112 and the water receiving surface 101 is 45° to 100°.

[0083] Based on the range of the included angle α in this embodiment, the guiding effect of the second guide section 112 on the airflow can be improved.

[0084] In some embodiments, the included angle α in the water receiving tray is 60° to 90°.

[0085] Based on the range of the included angle α in this embodiment, the guiding effect of the second guide section 112 on the airflow can be further enhanced.

[0086] In some embodiments of the water receiving tray, reference Figure 2 , Figure 4 and Figure 5 The water receiving tray air guide surface includes a third air guide section 113, a second air guide section 112, a third air guide section 113 and a first air guide section 111 arranged sequentially along the extension direction of the water receiving tray air guide surface.

[0087] Optionally, on a cross section perpendicular to the length direction of the water receiving tray 1, along the width direction of the water receiving tray 1, from the end closest to the tray body 10 to the end furthest from the tray body 10, the angle β between the third air guide section 113 and the height direction of the water receiving tray 1 is 0° to 90°.

[0088] In some embodiments of the water receiving tray, reference Figure 2 , Figure 4 and Figure 5 On a cross section perpendicular to the length of the water receiving tray 1, along the width of the water receiving tray 1, from the end closest to the tray body 10 to the end furthest from the tray body 10, the third air guide section 113 is inclined toward the bottom of the water receiving tray 1, and the angle β between the third air guide section 113 and the height direction of the water receiving tray 1 is 10° to 60°.

[0089] In this embodiment, after passing through the second guide section 112, the airflow flows further along the third guide section 113. Based on the range of the included angle β in this embodiment, the airflow can flow smoothly in the area where the third guide section 113 is located.

[0090] In some embodiments, the first air guide section 111 and the third air guide section 113 are smoothly transitioned in the water receiving tray.

[0091] Optionally, refer to Figure 2 , Figure 4 and Figure 5 The first air guide section 111 and the third air guide section 113 are smoothly transitioned through the first arc surface 114. Along the extension direction of the air guide surface of the water receiving tray, the two ends of the first arc surface 114 are tangent to the first air guide section 111 and the third air guide section 113, respectively.

[0092] The first arc surface 114 can be, for example, a circular arc surface.

[0093] In some embodiments, the second air guide section 112 and the third air guide section 113 are smoothly transitioned in the water receiving tray.

[0094] Optionally, refer to Figure 2 , Figure 4 and Figure 5 The second air guide section 112 and the third air guide section 113 are smoothly transitioned through the second arc surface 115. Along the extension direction of the air guide surface of the water receiving tray, the two ends of the second arc surface 115 are tangent to the second air guide section 112 and the third air guide section 113, respectively.

[0095] The second arc surface 115 can be, for example, a circular arc surface.

[0096] In this embodiment, by making the different air guide sections arranged adjacent to each other along the extension direction of the air guide surface of the water receiving tray smoothly transition, the outline of the air guide surface of the water receiving tray can be made smoother, thereby making the airflow delivery more stable.

[0097] In some embodiments of the water receiving tray, reference Figure 2 , Figure 4 and Figure 5 The inner surface of the tray 10 includes a water receiving surface 101 adjacent to the air guide surface of the water receiving tray. In a cross section perpendicular to the length direction of the water receiving tray 1, along the width direction of the water receiving tray 1, from the end adjacent to the air guide surface of the water receiving tray to the end away from the air guide surface of the water receiving tray, the water receiving surface 101 is inclined toward the bottom end of the water receiving tray 1, and the angle γ between the water receiving surface 101 and the width direction of the water receiving tray 1 is 30° to 90°.

[0098] In this embodiment, the condensate generated by the heat exchanger 4 can flow downward along the water receiving surface 101 and be collected by the plate 10. Based on the range of the included angle γ in this embodiment, the water receiving surface 101 has a good guiding effect on the condensate, and the condensate is not easy to accumulate on the water receiving surface 101.

[0099] In some embodiments, the included angle γ in the water receiving tray is 45° to 75°.

[0100] Based on the range of the included angle γ in this embodiment, the guiding effect of the water receiving surface 101 on the condensate can be further improved, so that the condensate is not easy to accumulate on the water receiving surface 101, nor is it easy to fall straight down and splash out.

[0101] The duct air conditioner provided in the embodiments of this disclosure includes a housing 2, a fan 3, a heat exchanger 4, and a water receiving tray 1 provided in the embodiments of this disclosure.

[0102] The casing 2 has a lower air outlet 21. A fan 3 is installed inside the casing 2. Along the air outlet direction of the fan 3, a heat exchanger 4 is positioned upstream of the lower air outlet 21. The width of the drip tray 1 is consistent with the width of the casing 2. The tray body 10 is positioned below the heat exchanger 4 to collect condensate generated by the heat exchanger 4 of the ducted air conditioner. At least a portion of the drip tray's air guide surface constitutes a side surface of the lower air outlet 21 located on one side of the casing 2 in the width direction.

[0103] Optionally, refer to Figure 1 The lower air outlet 21 is located on the bottom surface of the housing 2. Optionally, refer to... Figure 1The casing 2 has a side air outlet 22 located on one side along its width to allow air to be supplied from different directions. Optionally, the heat exchanger 4 serves as an evaporator. During cooling, the ducted air conditioner can supply air from either the lower air outlet 21 or the side air outlet 22, or simultaneously through both.

[0104] The duct unit provided in the embodiments of this disclosure has the advantages of the drip tray provided in the embodiments of this disclosure.

[0105] In some embodiments of the ducted air conditioning system, reference Figure 1 The projection of the edge of the heat exchanger 4 near the lower air outlet 21 along the height direction of the casing 2 is located inside the plate body 10. Along the width direction of the casing 2, the distance L between the edge of the water receiving tray air guide surface connected to the plate body 10 and the edge of the heat exchanger 4 near the lower air outlet 21 is 0 to 20 mm.

[0106] In this embodiment, along the width direction of the housing 2, the projection of the edge of the heat exchanger 4 near the lower air outlet 21 along the height direction of the housing 2 is located inside the plate 10. Based on the range of distance L in this embodiment, the condensate generated by the heat exchanger 4 can fall basically within the range of the plate 10 of the water receiving tray 1.

[0107] In some embodiments of the ducted air conditioning system, the distance L is 5 to 15 mm.

[0108] Based on the range of distance L in this embodiment, on the one hand, the value of distance L is not too small, so that even if the condensate generated by heat exchanger 4 is blown away by the airflow, it can fall into the range of the plate 10 of the water receiving tray 1; on the other hand, the value of distance L is not too large, so that the size of the water receiving tray along the width direction of the casing 2 is not too large. Therefore, when designing the structure of the duct air conditioner, it is not necessary to increase the size of the casing 2 in the width direction in order to ensure the size of the lower air outlet 21, nor is it necessary to limit the size of the lower air outlet 21 in order to limit the size of the casing 2 in the width direction.

[0109] In some embodiments of the ducted air conditioning system, reference Figure 1 and Figure 4 The ducted air conditioner includes a second air guide section 5. The first air guide section 11 and the second air guide section 5 are respectively disposed on both sides of the lower air outlet 21 along the width direction of the housing 2. The second air guide section 5 has a housing air guide surface 51. The first air guide section 111 is spaced apart from the housing air guide surface 51 and forms the sides of the lower air outlet 21 located on both sides of the housing 2 along the width direction. The first air guide section 111 and the housing air guide surface 51 are arranged approximately parallel to each other.

[0110] In this embodiment, the water tray air guide surface and the housing air guide surface 51 respectively constitute the two sides of the lower air outlet 21 located in the width direction of the housing 2. The area between the water tray air guide surface and the housing air guide surface 51 is the flow area of ​​the airflow in the lower air outlet 21. By arranging the first air guide section 111 and the housing air guide surface 51 approximately parallel to each other, the guiding effect of the first air guide section 111 and the housing air guide surface 51 on the airflow can be enhanced, so that the airflow passing through the lower air outlet 21 is transported smoothly as a whole.

[0111] In some embodiments of the ducted air conditioning system, reference Figure 1 and Figure 5 The ducted air conditioner includes a second air guide section 5. The first air guide section 11 and the second air guide section 5 are respectively disposed on both sides of the lower air outlet 21 along the width direction of the housing 2. The second air guide section 5 has a housing air guide surface 51. The first air guide section 111 is spaced apart from the housing air guide surface 51 and forms the sides of the lower air outlet 21 located on both sides of the housing 2 along the width direction. Among them, along the height direction of the housing 2 from top to bottom, the distance between the first air guide section 111 and the housing air guide surface 51 gradually decreases along the width direction of the housing 2.

[0112] In this embodiment, the distance between the first air guide section 111 and the air guide surface 51 of the housing 2 along the height direction from top to bottom varies along the width direction of the housing 2, which can realize variable diameter air supply. Furthermore, by gradually reducing the distance between the first air guide section 111 and the air guide surface 51 of the housing 2 along the width direction, the airflow velocity can be increased after passing through the lower air outlet 21.

[0113] In some embodiments of the ducted air conditioning system, reference Figure 4 and Figure 5 The angle δ between the air guide surface 51 of the casing and the height direction of the casing 2 is 5° to 35°.

[0114] Based on the range of the included angle δ in this embodiment, the airflow of the lower air outlet 21 has a better wall-mounted conveying effect at the location of the air guide surface 51 of the first housing.

[0115] In some embodiments of the ducted air conditioner, the included angle δ is 10° to 25°.
