Detailed Description

For the purposes of clarity, technical solutions and advantages of the present disclosure, the following further details the embodiments of the present disclosure with reference to the accompanying drawings.

The embodiment of the disclosure provides an air conditioner air duct device, which is used for being connected to an air outlet of an air conditioner so as to control the temperature of air blown out from the air outlet of the air conditioner.

Fig. 1 is a schematic structural diagram of an air conditioning duct device according to an embodiment of the present disclosure, and as shown in fig. 1, the air conditioning duct device includes a housing 1, an air guiding assembly 2, and a control assembly 3. The housing 1 has a cavity 10 therein. The housing 1 has a first opening and a second opening which are arranged opposite to each other and communicate with the cavity 10, respectively.

Fig. 2 is a cross-sectional view of the side of fig. 1, and in combination with fig. 2, the air guiding assembly 2 is located in the cavity 10 and connected with the housing 1, the air guiding assembly 2 divides the cavity 10 into an air inlet area 101, an air outlet area 102, an air blowing area 103 and an air return area 104, the air inlet area 101 and the air outlet area 102 are communicated with the first opening, and the air blowing area 103 and the air return area 104 are communicated with the second opening. The control assembly 3 is movably located in the cavity 10 and is connected with the air guide assembly 2, the control assembly 3 can move between a first position and a second position, when the control assembly 3 is located in the first position, the air inlet area 101 and the air outlet area 103 are communicated to form an air outlet channel, the air outlet area 102 and the air return area 104 are communicated to form an air return channel, the air outlet channel is used for blowing air into a target environment, the air return channel is used for discharging exchange air flow in the target environment, when the control assembly 3 is located in the second position, the air inlet area 101 and the air outlet area 102 are communicated to form an air outlet channel, and the air outlet channel is used for refluxing air flow blown by an air conditioner.

When the air conditioner air duct device provided by the embodiment of the disclosure is connected to an air outlet of an air conditioner, the air conditioner air duct device can be connected with the air conditioner through the shell 1 because the air conditioner air duct device comprises the shell 1, the air guide assembly 2 and the control assembly 3. Meanwhile, because the air guide component 2 is positioned in the cavity 10 and divides the cavity 10 into the air inlet area 101, the air exhaust area 102 and the air blowing area 103, the air guide component can be communicated with an air outlet of an air conditioner through the air inlet area 101, simultaneously, air is blown into a target closed environment through the air blowing area 103, and meanwhile, air exchanged in the target environment is discharged through the air return area 104 and the air exhaust area 102, so that circulation of air flow is realized.

In addition, since the control assembly 3 of the device can move between the first position and the second position, when the control assembly 3 is positioned at the first position, the air inlet area 101 and the air outlet area 102 are communicated through the air blowing area 103 and the air return area 104, and when the control assembly 3 is positioned at the second position, the air inlet area 101 and the air outlet area 102 are directly communicated. It is possible to locate the control assembly 3 in different positions so that the air blown by the air conditioner can be blown directly into the target environment or not. That is, it is possible to flexibly control the control unit 3 to selectively blow air into the target environment according to the temperature of the air flow blown out by the air conditioner. For example, when the air conditioner needs to blow in 10 degrees of cold air in the target environment, after the air conditioner is turned on, the air blown by the air conditioner may be blown into the air conditioner air duct device first, and the control unit 3 is controlled to be at the second position, and no cold air is blown into the blowing area 103 (the airflow direction may be referred to by the dashed arrow in fig. 2), and when the air blown by the air conditioner falls to 10 degrees, the control unit 3 is controlled to be at the first position, and the cold air is blown into the blowing area 103 through the air inlet area 101 (the airflow direction may be referred to by the solid arrow in fig. 2).

It can be seen that the above apparatus enables the temperature of the air blown out by the air to be controlled within a suitable range, so that the target environment can be maintained within a constant range.

With continued reference to FIG. 2, the air guide assembly 2 optionally includes an air guide 21 and a baffle 22. The air guide 21 is located in the cavity 10 and is connected to the housing 1, the air guide 21 has opposite first and second sides, and the partition 22 is located on the first side and is connected to the middle of the air guide 21.

In the above implementation manner, the air guide assembly 2 is configured as above, and the cavity 10 may be divided into four independent areas by the air guide 21 and the partition 22, thereby forming the air inlet area 101, the air outlet area 102, the air blowing area 103, and the air return area 104. Meanwhile, the air intake area 101 and the air exhaust area 102 may be communicated through the first communication hole 220, while the second communication hole 2101 is used for communicating the air intake area 101 with the air blowing area 103, and the third communication hole 2102 is used for communicating the air exhaust area 102 with the return area 104.

The following briefly describes a use process of the air conditioner air duct device provided by the embodiment of the present disclosure:

the air conditioner air duct device is connected between the air conditioner and the medical transfer box.

When the medical transfer box is set in a certain temperature range, the medical transfer box starts working. Firstly, the air conditioner is started, a command is sent to the first driving motor 331 and the second driving motor 332 through the controller, the first driving motor 331 and the second driving motor 332 control the first rotating plate 31 and the second rotating plate 32 to rotate, so that the air inlet area 101 and the air outlet area 102 are directly communicated, a small self-circulation system of the air conditioner is formed, and the air outlet temperature of the air conditioner quickly reaches the set temperature required in the medical transfer box.

When the air outlet temperature of the air conditioner rapidly reaches the required set temperature in the medical transfer box, the controller sends an instruction to the first driving motor 331 and the second driving motor 332, the first driving motor 331 and the second driving motor 332 control the first rotating plate 31 and the second rotating plate 32 to rotate, the air inlet area 101 is communicated with the air blowing area 103, the air exhaust area 102 is communicated with the air return area 104, and at the moment, the air reaching the set temperature is blown into the transfer box through the air blowing area 103.

When the temperature of the medical transfer box reaches the lower limit of the set temperature, the blowing area 103 stops blowing air into the medical transfer box, meanwhile, the air inlet area 101 is directly communicated with the air exhaust area 102, the air conditioner is not stopped, and the small self-circulation system of the air conditioner is continuously realized.

When the temperature in the medical transfer box is raised to the upper limit of the set temperature, the blowing area 103 is opened again to blow the air to the medical transfer box, and the air exhausting area 102 is communicated with the air returning area 104, so that the air with the air conditioner reaching the set temperature is blown into the transfer box. Through the automatic control mode of the air duct system, the temperature of the medical transfer box is always ensured to be within a set temperature range.
