[0070] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0071] In this application, the central air conditioner duct type indoor unit (abbreviated as duct unit) belongs to the air conditioner, and the air conditioner includes the duct unit (i.e. the air conditioner indoor unit) and the air conditioner outdoor unit (i.e. the air conditioner outdoor unit), and the air conditioner performs the refrigeration cycle of the air conditioner by using a compressor, a condenser, a throttling device and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat exchanged.

[0072] The compressor compresses the low-temperature and low-pressure refrigerant gas and discharges the high-temperature and high-pressure refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0073] The throttling device expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the throttling device and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the whole cycle, the air conditioner can adjust the temperature of the indoor space.

[0074] The air conditioner includes an air conditioner indoor unit and an air conditioner outdoor unit. The air conditioner outdoor unit refers to the part of the refrigeration cycle including a compressor and an outdoor heat exchanger. The air conditioner indoor unit includes an indoor heat exchanger, and a throttling device can be provided in the air conditioner indoor unit or the air conditioner outdoor unit.

[0075] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0100] The heat exchanger 2 is located in the heat exchange chamber and is disposed near the air inlet 11. Figure 4 The heat exchanger 2 is roughly "V"-shaped, and the heat exchanger 2 almost covers the entire air flow cross-section in the air flow direction between the air inlet 11 and the air outlet 12, thereby increasing the heat exchange area of ​​the heat exchanger 2, improving the heat exchange efficiency of the air duct machine 100, and increasing the amount of air exchanged.

[0101] The fan 3 may be a centrifugal fan. The fan 3 may include a volute 31 .

[0102] The volute 31 may include an air inlet 311. The air inlet 311 is used to take air into the volute 31.

[0111] In some embodiments of the present application, the duct air conditioner may include an electronic control component, which is used to at least control the compressor and the fan to implement various preset functions of the duct air conditioner 100.

[0112] In the related art, an electric control area is provided on the partition 41, and a mounting cavity is formed between the fan bracket and the housing 1 corresponding to the electric control area. The mounting cavity is independent of the air outlet cavity 42, and the mounting cavity can accommodate and protect the electric control components.

[0113] The installation cavity is located at the top of the air duct at the air outlet. Installing the electronic control component in the installation cavity will affect the layout of the air duct in the housing 1. The small size of the installation cavity makes the components inside the electronic control component compact, resulting in low assembly efficiency and poor electromagnetic compatibility. In addition, the small installation space makes on-site maintenance and disassembly extremely inconvenient, and the maintenance time is long, which increases the user's maintenance cost and reduces the product competitiveness.

[0114] In order to solve the above technical problems, in some embodiments of the present application, the electronic control component is split into two functional modules, namely a driving module 5 and a control module 7 .

[0115] Specifically, refer to Figure 6 In this embodiment, the electric control component may include a driving module 5. The driving module 5 is disposed in the fan cavity, and the driving module 5 is electrically connected to the fan.

[0116] As is known, the drive module 5 is not prone to failure, the probability of replacement and repair is relatively low, and the heat generated by the drive module 5 is greater than the heat generated by the control module 7.

[0117] In this embodiment, the driving module 5 is disposed in the fan cavity so as to be in the wind field, so that heat dissipation and temperature reduction can be timely achieved, thereby protecting the safety of the driving module 5 .

[0118] Continue to refer Figure 6 The electric control assembly may include a control module 7. The control module 7 is disposed on the housing 1 and is located outside the housing 1. The control module 7 is electrically connected to the drive module 5 through an electrical connection line.

[0119] As is known, the control module 7 has many functions, and is usually provided with alarm, fault code display, air volume dial debugging switch light, etc. The control module 7 is used more frequently, and its heat generation is less than that of the drive module 5.

[0120] In this embodiment, when setting the position of the control module 7, the problem of high heat dissipation of electrical components is not considered. The control module 7 is set outside the housing 1, and the operating space is very large. When checking the fault code, the visual effect is intuitive, which greatly improves the convenience of on-site debugging and maintenance and improves the maintenance efficiency. The control module 7 is set outside the housing 1, and there is no risk of condensation, which improves the safety performance of the control module 7.

[0121] In addition, in this embodiment, the driving module 5 and the control module 7 are arranged as a separate structure, which can avoid signal interference or mutual influence between the two, and improve the stability and reliability of operation.

[0122] In some embodiments of the present application, reference is made to Figure 3 , the control module 7 can be installed on the front panel 13. In some other embodiments, refer to Figure 8 , the control module 7 can be installed on one of the two side panels 152 .

[0123] refer to Figure 6 , the driving module 5 is located between the fan and the front panel 13. That is to say, the driving module 5 is arranged close to the front panel 13 relative to the fan, which is convenient for later maintenance thereof.

[0124] By installing the control module 7 on the side panel 152 or the front panel 13, the installation position of the external control module 7 can be adjusted. According to the user's on-site installation environment, it can be placed on the front, left or right side of the duct machine to facilitate subsequent maintenance.

[0125] The driving module 5 may include a driving board 51. The driving board 51 is at least electrically connected to the motor 33, and is used to at least drive the motor to run, and further drive the fan.

[0126] The driving module 5 may include a heat sink 50.
