Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to an air conditioner. Background Art

[0002] With the continuous development of social economy and science and technology, the scope of use of air conditioners has gradually become wider. Previously, they were only used for people, but now they are gradually being widely used to cool a variety of equipment, such as in vehicle cabins and ship cabins. The spatial environment for installing air conditioners varies from device to device. When air conditioners are placed in different devices, they may be subject to space restrictions in different directions. For example, in the technology known to the inventor, the electronic control module is generally located at the top. The electronic control module includes circuit components such as the control motherboard, driver board, and controller elements. When maintenance and disassembly are required, the top cover needs to be removed, and the maintenance space is located above the unit. However, many special air conditioners currently used in vehicle cabins are equipped with a rain shield on the top of the unit for daily rain and sun protection, resulting in no operating space on the top of the unit. When the electronic control module needs to be inspected and maintained, the awning needs to be removed, which is a lot of work and very inconvenient for daily inspection and maintenance. For some other equipment, the space restrictions for the air conditioner may come from the side of the air conditioner, etc. Therefore, it is difficult for air conditioners in the prior art to meet the needs of electronic control module inspection and maintenance in different equipment installation spaces.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to actual proportional relationships. The technology, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be considered as part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0036] In the description of the present invention, it should be understood that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0037] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections or indirect connections through an intermediary.

[0039] like Figures 1 to 9 As shown, the air conditioner of this embodiment includes a chassis 1, a refrigeration cycle component and an electronic control module 3.

[0040] The chassis 1 includes a plurality of panels 12. The plurality of panels 12 are located at different sides of the chassis 1, and the chassis 1 is provided with a plurality of first connection structures at different positions.

[0041] The multiple panels 12 are located on different sides of the chassis 1, that is, the multiple panels 12 are located in different directions of the chassis 1, and the multiple panels 12 face different directions. The six panels are located on six different sides of the chassis 1, and the six panels face six different directions of the chassis 1 (in Figure 1 In the embodiment, the reader is positioned inside the chassis, facing one panel, and the six panels are facing six directions, namely, front, back, left, right, up, and down.

Figure 6 and Figure 7As shown, when the second connection structure is connected to the top connection structure, the mounting side of the electronic control mounting plate 32 faces the top panel. This embodiment provides at least two of the front connection structure, the side connection structure, and the top mounting structure. By connecting the second connection structure to different connection structures, the electronic control module can be installed in different locations on the chassis, allowing panels for maintaining the electronic control module to be located on different sides of the chassis.

The side of the electric control mounting plate 32 mainly used to install circuit components is its mounting side. The second connecting structure is used to connect to the first connecting structure to fix the electric control box 31 in the chassis 1. This embodiment can better protect the electric control mounting plate through the provision of the electric control box, and also enables the electric control module to form a more complete and independent whole, which is convenient for adjusting the overall position.

The frame of the heat dissipation fan is fixedly connected to the fan panel, and the fan panel is hinged to the frame 11. In the embodiment shown in the figure, the fan module also includes a guide ring fixedly connected to the fan panel for guiding the air outlet of the heat dissipation fan. In this embodiment, the fan panel can be opened by rotating the fan panel relative to the frame 11. At the same time, since the frame of the heat dissipation fan is fixedly connected to the fan panel, the rotation of the fan panel can directly bring the heat dissipation fan out of the chassis, making it convenient for repair and maintenance of the heat dissipation fan.

[0052] In some embodiments, a panel facing the installation side of the electric control mounting plate of the electric control box body is hinged to the chassis or detachably connected to the chassis, and the panel is opened by rotating the panel relative to the chassis or detaching the panel from the chassis.

The structure of this embodiment is simple and compact.

[0054] In some embodiments, as Figure 1 and Figure 8 As shown, the refrigeration cycle components further include an evaporator 41, an evaporation fan 43, and an air duct component disposed within the chassis 1. The chassis 1 is provided with an evaporation return air port 441 communicating with the evaporator 41 and an evaporation supply air port 442 communicating with the outlet of the evaporation fan 43. The air duct component includes an air duct wall 42 disposed around the surface of the evaporator 41 away from the evaporation return air port. The evaporation return air port is used to input air from the external environment for heat exchange with the evaporator 41, and the evaporation supply air port is used to output air that has undergone heat exchange with the evaporator 41 to the outside. The air duct wall 42 forms the wall surface of the evaporation air duct for guiding the air that has undergone heat exchange with the evaporator 41. The two ends of the evaporation air duct are respectively connected to the surface of the evaporator 41 away from the evaporation return air port and to the inlet of the evaporation fan 43. The air duct wall 42 includes a water receiving pan 421 located below the evaporator 41 for receiving condensed water on the surface of the evaporator 41. In the embodiment shown in the figure, the evaporation fan is a centrifugal fan. In this embodiment, ambient air enters through the evaporation return air port, exchanges heat with the evaporator, enters the evaporation duct, flows into the evaporation fan inlet, and finally exits through the evaporation fan outlet 43 to the evaporation air supply port 442 for delivery to the ambient air. This embodiment achieves sealed flow of evaporation heat exchange airflow. The integrated design of the duct wall 42 and the water tray not only allows for the collection of evaporator condensate, but also further improves the airtightness of the duct, resulting in a compact structure.

[0055] In some embodiments, as Figure 8As shown, the refrigeration cycle components further include an electric heater 45 disposed on a surface of the evaporator 41 away from the evaporation return air outlet. The electric heater 45 is mounted to the surface of the evaporator 41 by bolts or other means. The electric heater 45 is used to heat the air passing through the evaporator 41. In this embodiment, the electric heater 45 can heat the air in the external environment.

[0056] In some embodiments, as Figure 10 As shown, the air conditioner also includes an aviation plug 5 disposed on and passing through the chassis 1.

As shown, aviation plug 5 includes a connecting cell 51 connected to the cell of the electrical circuit and a sealing gasket 52 for sealing the connection between aviation plug 5 and the chassis 1. By providing aviation plug 5 to electrically connect the electrical circuits within the chassis 1 with the electrical circuits outside the chassis 1, this embodiment can improve the sealing of the electrical circuit connection of the air conditioner.

[0057] In some embodiments, the air conditioner further includes a wall connector provided on and passing through the chassis 1, the wall connector being used to connect the pipes inside the chassis 1 with the pipes outside the chassis 1. In this embodiment, by providing the wall connector to connect the pipes inside the chassis 1 with the pipes outside the chassis 1, the sealing performance of the pipe connection of the air conditioner can be improved.

[0058] In some embodiments, as Figure 11 As shown, the through-wall connector includes a connecting pipe 63 that passes through the mounting hole of the chassis 1, an annular flange 61 provided on the connecting pipe 63, an external thread provided on the outer circumference of the connecting pipe 63, and a nut 62 that cooperates with the external thread. The radial dimension of the annular flange 61 is larger than the radial dimension of the mounting hole. The nut 62 cooperates with the external thread to press the chassis 1 from both the inside and outside of the chassis 1 together with the annular flange 61. The through-wall connector of this embodiment can effectively achieve a tight seal when the pipeline is connected through the chassis.

[0059] In some Figure 2 、 Figure 8 and Figure 9 In the embodiment shown, when designing the air conditioner, the cooling capacity of the air conditioner and the fan selection are used to quickly calculate the length, width and height of the chassis, and a modular design is adopted to efficiently utilize the structural space, reasonably layout, and improve the energy efficiency level.

[0060] First, when designing an air conditioner, component selection is performed based on design objectives such as cooling capacity, power distribution power, power supply, and operating temperature. After the selection and calculation design are completed, the air conditioner design can be performed based on the component size and the calculated two components. In the embodiment shown in the figure, the air conditioner chassis is in the shape of a square cabin, and the chassis length j = the width a of the electrical control cabinet + the diameter f of the fan module + the thickness g of the condenser module + the constant y (the clearance margin of each component, 0≤y≤200mm); the chassis width e = the height a of the electrical control cabinet + the thickness c of the evaporator + the diameter d of the evaporating fan + the constant y (the clearance margin of each component, 0≤y≤200mm); and the chassis height = the diameter f of the fan module + the height a of the electrical control cabinet + the constant y (the clearance margin of each component, 0≤y≤200mm).

[0061] For the design of the evaporator module, the evaporator, evaporation fan, evaporation duct and electric heating element are first designed into a module. The diameter d of the evaporation fan is used to design the width and thickness of the evaporation duct. Then the height of the evaporation duct p = the height of the chassis - the height x of the evaporation fan. The width and length of the evaporator are equal to the width and height p of the evaporation duct respectively. According to the heat exchange calculation, the thickness c of the evaporator is obtained. After this parametric module design, the minimum size of the evaporator module can be quickly calculated, the layout is compact, and the evaporation duct layout is reasonable, the wind resistance is small, and the noise reduction and other performance indicators can be improved.

[0062] The electronic control installation board includes a driver board, a power filter board and a main board for controlling weak current. The size a of the electronic control box is generally determined by the outer dimensions of the driver board, which is larger inside the electrical box. Generally, the width of the driver board is about 200mm.
