Description

Technical Field

[0001] The utility model relates to the field of air conditioners, and specifically provides a duct unit and an air conditioner. Background Art

[0002] Duct air conditioner is a common indoor air conditioner, which is also called duct air conditioner, air conditioner duct unit or duct air conditioner. It is usually hidden and installed in the ceiling, does not take up ground space, and can be better integrated into the decoration. It has the advantages of beautiful installation, space saving and high cost performance. Therefore, it is often used in restaurants, central office buildings and other places.

[0003] A ducted air conditioner typically consists of a housing, a fan, and a heat exchanger. When the ducted air conditioner is in operation, the fan draws in indoor air through the air inlet on the housing and blows air toward the heat exchanger. After the air is heated by the heat exchanger, it is discharged through the air outlet on the housing. To improve heat exchange efficiency, heat exchangers typically utilize multiple stacked heat exchange components. However, due to the limited space in ducted air conditioners, the number of heat exchange components is limited, resulting in relatively low heat exchange efficiency.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Utility Model Content

Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0040] Reference Figure 2-5 , describe the air duct machine of this application.

[0041] Reference Figure 1 A conventional ducted air conditioner includes a housing 1 and a heat exchanger 2 disposed within the housing 1. The heat exchanger 2 comprises a plurality of heat exchange elements 21 stacked along a first direction to form a rectangular shape, intended to improve the heat exchange efficiency of the ducted air conditioner. However, due to the limited space within the ducted air conditioner, the number of heat exchange elements 21 is limited, resulting in a relatively low heat exchange efficiency.

[0042] To address the low heat exchange efficiency of heat exchanger 2 in existing ducted air conditioners, the ducted air conditioner of the present application includes a body 1 and a heat exchanger 2. Heat exchanger 2 is disposed within body 1 and includes multiple heat exchange elements 21. The multiple heat exchange elements 21 are sequentially connected along a first direction, and the angle between each heat exchange element 21 and a plane formed by the second and third directions is greater than 0° and less than 90°. The first direction, the second direction, and the third direction are perpendicular to each other.

[0043] The present application arranges multiple heat exchange elements 21 in sequence end to end along the first direction, and ensures that each heat exchange element 21 forms an angle greater than 0° and less than 90° with the plane formed by the second direction and the third direction, so that the heat exchange area of ​​the heat exchanger 2 is significantly increased compared with other heat exchangers occupying the same space, thereby improving the heat exchange efficiency and solving the problem of low heat exchange efficiency of the heat exchanger 2 in the existing duct unit.

[0044] The first direction refers to Figure 1-5 The Z direction is shown, which includes the positive direction and the negative direction indicated by the arrow. The second direction refers to Figure 1-5 The Y direction shown includes the positive direction and the negative direction indicated by the arrow. The third direction refers to Figure 1-5 The X direction is shown, which includes a positive direction and a negative direction indicated by arrows.

[0045] Further reference below Figure 2-5 A preferred embodiment of the ducted air conditioner of the present application is described below. Those skilled in the art will understand that the following embodiments are merely intended to illustrate the principles of the present application and are not intended to limit the scope of protection of the present application. On the premise that the ducted air conditioner includes at least a body 1 and a heat exchanger 2, those skilled in the art may adjust the following configuration to adapt the present application to more specific application scenarios.

[0046] like Figure 2 and Figure 4 As shown, the ducted air conditioner includes a body 1, a fan unit and a heat exchanger 2 disposed within the body 1. An air inlet 12 is provided on one side of the body 1 along the second direction, and an air outlet 11 is provided on the other side. The fan unit is disposed near the air outlet 11, with its outlet corresponding to the air outlet 11. The heat exchanger 2 is disposed near the air inlet 12. When the ducted air conditioner is in operation, the fan 7 can generate negative pressure on one side of the air outlet 11, thereby guiding air into the body 1 through the air inlet 12 on the body 1. After entering the body 1, the air exchanges heat with the heat exchanger 2 and is ultimately discharged through the air outlet 11.

[0047] Of course, the position of the air outlet 11 is not fixed in this application, and those skilled in the art can adjust it as needed, as long as the outlet of the fan unit corresponds to the air outlet 11. For example, the air outlet 11 can also be set on one side of the body 1 along the first direction or the third direction.

[0048] See next Figure 2 The fan unit includes two fans 7, which are arranged in sequence along the third direction and are both located near the air outlet 11. Two air outlets 11 are provided on the body 1. The two air outlets 11 are arranged in sequence along the third direction and correspond one-to-one with the two fans 7, so that the fans 7 can discharge the gas in the body 1 through the corresponding air outlets 11.

[0049] It should be noted that the present application has no limitation on the specific type of the blower 7, as long as it is conducive to discharging the gas in the body 1 from the air outlet 11. For example, both blowers 7 are cross-flow fans.

[0050] Of course, the number of fans 7 set in this application is not fixed, and those skilled in the art can adjust it as needed. For example, the number of fans 7 can also be 1, 3, or other numbers. Among them, the number of fans 7 is the same as the number of air outlets 11. For example, when the number of fans 7 is 1, the number of air outlets 11 is also 1; when the number of fans 7 is 3, the number of air outlets 11 is also 3. Alternatively, the number of fans 7 is different from the number of air outlets 11. For example, when the number of fans 7 is 2 and the number of air outlets 11 is 1, the air outlet 11 corresponds to the outlets of two fans 7 at the same time, so that the two fans 7 discharge the gas in the body 1 through the same air outlet 11.

[0051] See next Figure 2-3 The heat exchanger 2 includes seven heat exchange elements 21, which are connected in sequence along the first direction, and the angle between each heat exchange element 21 and the plane formed by the second direction and the third direction is the same, and the angle is greater than or equal to 30° and less than 90°. Through the above-mentioned setting method, the heat exchange area of ​​the heat exchanger 2 is significantly increased compared with other heat exchangers 2 of the same volume type, thereby improving the heat exchange efficiency.

[0052] Of course, the present application does not impose a fixed number and arrangement of the heat exchange elements 21, and those skilled in the art can adjust them according to the specific application scenario. For example, the number of heat exchange elements 21 can also be 2, 3, or another number. And / or, the heat exchange element 21 can be a heat exchange plate. In addition, the present application does not limit the connection method between multiple heat exchange elements 21, as long as multiple heat exchange elements 21 can be connected together to form a heat exchanger 2. For example, multiple heat exchange elements 21 can be integrally formed, or multiple heat exchange elements 21 can be connected together by a fixed method such as welding.

[0053] Furthermore, the specific values ​​for the angles between each heat exchange element 21 and the plane formed by the second and third directions are not fixed in this application and may be adjusted by those skilled in the art based on actual circumstances. For example, the angles between each heat exchange element 21 and the plane formed by the second and third directions may vary, as long as the angles are greater than or equal to 30° and less than 90°. Alternatively, the angle between at least one of the multiple heat exchange elements 21 and the plane formed by the second and third directions may be greater than 0° and less than or equal to 30°.

[0054] See next Figure 4-5The body 1 also includes an air inlet frame 3 and a filter 4. The air inlet frame 3 is arranged at the air inlet 12 of the body 1. The air inlet frame 3 is composed of four side panels surrounding the air inlet 12. These four side panels are, in order, a first side panel 31, a second side panel 32, a third side panel 33, and a fourth side panel 34. The first side panel 31 and the third side panel 33 are respectively located on either side of the air inlet 12 along a first direction, and the second side panel 32 and the fourth side panel 34 are respectively located on either side of the air inlet 12 along a third direction. The third side panel 33 is fixed to the body 1, the second side panel 32 and the fourth side panel 34 are mounted on the third side panel 33 by screws 5, and the first side panel 31 is mounted between the second side panel 32 and the fourth side panel 34 by screws 5.

[0055] It should be noted that the present application does not limit the method for fixing the third side panel 33 to the body 1, as long as the third side panel 33 can be fixed to the body 1. For example, the third side panel 33 can be welded to the body 1, or the third side panel 33 can be fixed to the body 1 by screws 5.

[0056] Of course, the manner in which the air inlet frame 3 is mounted at the air inlet 12 of the housing 1 is not fixed in this application, and those skilled in the art may adjust it as needed. For example, the second side panel 32 and the third side panel 33 are fixed to the housing 1, the first side panel 31 is fixed to the first side panel 31 by screws 5, and the fourth side panel 34 is fixed to the first side panel 31 and the third side panel 33 by screws 5.

[0057] See also Figure 5 A reserved opening 311 is provided on the first side panel 31, and a plurality of first plug-in structures are provided on the inner wall of the third side panel 33. The first plug-in structure is a connecting frame 6 formed with a plug-in slot. The filter 4 includes a frame 41 and a filter body 42 provided on the frame 41. The frame 41 of the filter 4 can serve as a plug-in plate, so that when the filter 4 is installed in the air inlet frame 3 through the reserved opening 311, one end of the frame 41 along the first direction can be inserted into the plug-in slot on the connecting frame 6, and the other end rests on the reserved opening 311, so that the filter 4 can be detachably installed on the air inlet frame 3. The filter 4 can be disassembled and assembled not only through the reserved opening 311, but also by disassembling and assembling the first side panel 31, the second side panel 32 and the fourth side panel 34. The filter 4 can be disassembled and assembled by various means, which facilitates the replacement or cleaning of the filter 4 and improves the practicality of the air duct air conditioner.

[0058] Of course, the present application does not fix the location of the reserved opening 311, and those skilled in the art can adjust it according to the setting needs. For example, the reserved opening 311 can also be set on the second side panel 32, the third side panel 33 or the fourth side panel 34. In addition, the present application does not fix the number of reserved openings 311, and those skilled in the art can adjust it according to the specific application scenario. For example, the reserved opening 311 can be set on both the first side panel 31 and the second side panel 32, so that the filter 4 can be installed on the air inlet frame 3 from the reserved opening 311 on the first side panel 31, and can also be installed on the air inlet frame 3 from the reserved opening 311 on the second side panel 32.

[0059] In addition, the specific arrangement of the first plug-in structure and the second plug-in structure in the present application is not fixed and can be adjusted by those skilled in the art as needed. For example, the first plug-in structure is a connecting frame 6 formed with a plug-in slot, and the second plug-in structure is a plug-in plate arranged on the frame 41. Alternatively, the first plug-in structure is a plug-in plate, and the second plug-in structure is a connecting frame 6 arranged on the frame 41, and the connecting frame 6 is formed with a plug-in slot. Alternatively, the first plug-in structure is a plug-in slot or a plug-in hole, and the second plug-in structure is a plug-in plate arranged on the frame 41 or the frame 41 itself. Alternatively, the first plug-in structure is a plug-in plate, and the second plug-in structure is a plug-in slot arranged on the frame 41. It should be noted that when the side panels on the air inlet frame 3 that are opposite to each other are provided with reserved openings 311 at the same time, when the filter 4 is inserted from one reserved opening 311, the other reserved opening 311 can serve as a plug-in hole so that the frame 41 can be inserted therein, thereby achieving the installation of the filter 4.

[0060] In addition, the present invention also provides an air conditioner, which includes the duct air conditioner described in any of the above embodiments.

[0061] Thus far, the technical solutions of the present application have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present application.
