In recent years, air conditioners with air purification functions have become increasingly popular. However, the mobile air conditioners currently on the market have limited functionality, providing only cooling or heating.

[0003] Moreover, most mobile air conditioners on the market are driven by centrifugal fans. Although centrifugal fans can provide a large air volume, the air outlet area is small, resulting in a limited air supply range and low efficiency in affecting indoor air. Summary of the Invention

[0004] The problem solved by the present invention is that the existing mobile air conditioner has a small air outlet area, a limited air supply range and a single function.

[0014] In this way, the first air inlet and the first air outlet are respectively located on two adjacent sides of the shell, and the distance between them is moderate to facilitate communication through the interior of the shell. The mutual interference between the air inlet and the air outlet is small, and the area of ​​the first air inlet can be ensured to be large, thereby ensuring the efficiency of indoor air purification.

[0015] In an optional embodiment, the second air inlet is opened on the front of the shell, and the second air outlet is opened on the top surface of the shell.

[0019] In an optional embodiment, a third air inlet and a third air outlet are provided on the shell, and the third air inlet, the centrifugal fan and the third air outlet are connected in sequence to form an exhaust passage.

[0020] In this way, an exhaust channel is added to realize the function of indoor ventilation.

[0021] In an optional embodiment, the mobile air conditioner further includes a connecting pipe, one end of which is connected to the third air outlet, and the other end of which is connected to the outside of the room.

[0022] In this way, a connecting pipe leading to the outside of the room is connected outside the third air outlet, which reduces the position restriction of the third air outlet, reduces the difficulty of structural design and production, and ensures the effect of the ventilation function.

[0024] In this way, the third air inlet and the third air outlet are respectively located on two adjacent sides of the shell, and the distance between the two is moderate to facilitate communication through the interior of the shell. The mutual interference between the air inlet and the air outlet is small, and the area of ​​the third air inlet can be ensured to be large, thereby ensuring the efficiency of indoor ventilation.

[0025] In an optional embodiment, the mobile air conditioner further includes a first baffle, which is installed in the exhaust passage and located between the centrifugal fan and the third air outlet, and is used to control the opening or closing of the exhaust passage.

[0026] In this way, when exhaust is not required, the first baffle can be controlled to close the exhaust passage to avoid air leakage inside the shell, so as to ensure that other operating modes are carried out efficiently.

[0027] In an optional embodiment, the mobile air conditioner further includes a second baffle, which is installed in the air purification channel and located between the centrifugal fan and the second air outlet, and is used to control the opening or closing of the air purification channel.

[0028] In this way, when air purification is not required, the second baffle can be controlled to close the air purification channel to avoid air leakage inside the shell, so as to ensure that other operating modes are carried out efficiently. BRIEF DESCRIPTION OF THE DRAWINGS

In this way, the area of ​​the first air inlet 21 can be ensured to be large, thereby ensuring the efficiency of regulating the indoor air temperature.

[0041] A third air inlet 25 is provided at the lower back of the housing 2, and the third air inlet 25 serves as an exhaust passage 13 ( Figure 6 As shown in FIG, the third air inlet 25 extends along the length direction of the housing 2. In this way, the area of ​​the third air inlet 25 can be ensured to be large, thereby ensuring the efficiency of indoor ventilation.

[0042] See also Figure 2 The top surface of the housing 2 is provided with a first air outlet 22, which serves as the air outlet of the cooling channel 11 and extends along the length of the housing 2. In this way, the area of ​​the first air outlet 22 can be ensured to be large, thereby ensuring the efficiency of regulating the indoor air temperature.

[0043] The first air inlet 21 and the first air outlet 22 are respectively located on two adjacent side surfaces of the shell 2. The distance between the two is moderate so as to facilitate internal communication through the shell 2. The mutual interference between the air inlet and the air outlet is small, and the area of ​​the first air inlet 21 can be ensured to be large, thereby ensuring the efficiency of indoor air purification.

[0044] The top surface of the housing 2 is also provided with a second air outlet 24, which serves as the air purification channel 12 ( Figure 6 As shown), the second air outlet 24 is convenient for inputting fresh air into the room.

[0045] In other embodiments, the second air outlet 24 may also serve as an air outlet of a fresh air channel, so as to facilitate delivery of fresh air into the room to improve the freshness of the indoor air.

[0046] See also Figure 3 The front of the housing 2 is provided with a second air inlet 23, which serves as the air purification channel 12 ( Figure 6 As shown), the second air inlet 23 is connected to the outside to inhale fresh air from the outside. Moreover, the second air inlet 23 is connected to the second air outlet 24 (see FIG. Figure 2 ) are moderately spaced to facilitate internal communication through the shell 2.

[0047] In other embodiments, the second air inlet 23 may also serve as an air inlet of a fresh air channel, so as to facilitate the introduction of outdoor fresh air to improve the freshness of the indoor air.

[0048] An air duct leading to the outside of the room (not shown in the figure) can also be connected to the outside of the second air inlet 23 to reduce the position restriction of the second air inlet 23, reduce the difficulty of structural design and production, and ensure the effect of the fresh air function.

[0049] See also Figure 4 A third air outlet 26 is provided on the left side of the housing 2, and the third air outlet 26 serves as the exhaust passage 13 ( Figure 6 The third air outlet 26 can be connected to a connecting pipe (not shown) leading to the outside of the room to reduce the position restrictions of the third air outlet 26, reduce the difficulty of structural design and production, and ensure the effectiveness of the ventilation function.

[0050] In other embodiments, the third air outlet 26 may also be opened on the right side of the housing 2 to achieve the same effect.

[0051] In this way, the third air inlet 25 and the third air outlet 26 are respectively located on two adjacent sides of the shell 2, and the distance between the two is moderate to facilitate communication through the interior of the shell 2, and the mutual interference between the air inlet and the air outlet is small, and the area of ​​the third air inlet 25 can be ensured to be large, thereby ensuring the efficiency of indoor ventilation.

[0052] See also Figure 5 and Figure 6 The mobile air conditioner 1 further includes an evaporator 3 , a cross-flow fan 4 , a filter 5 , a centrifugal fan 6 , a condenser 7 , a compressor 8 , a first baffle 9 and a second baffle 10 .

[0053] Evaporator 3 and crossflow fan 4 are mounted within housing 2. First air inlet 21, evaporator 3, crossflow fan 4, and first air outlet 22 are sequentially connected to form cooling duct 11. Thus, by installing crossflow fan 4 within cooling duct 11, air is blown into the room to regulate the indoor temperature. This increases the air outlet area, enables a longer air supply distance, improves the air supply range, and improves the efficiency of regulating the indoor air temperature.

[0054] The filter 5 and the centrifugal fan 6 are installed in the housing 2, and the filter 5 is installed inside the second air inlet 23. The second air inlet 23, the filter 5, the centrifugal fan 6 and the second air outlet 24 are connected in sequence to form the air purification channel 12. In this way, the air purification channel 12 is added and the centrifugal fan 6 is installed in the air purification channel 12, which can provide a large air volume to the room, has a good air purification effect in the room, and improves the cleanliness of the indoor air.

[0055] The compressor 8 and the condenser 7 are installed in the housing 2. The condenser 7 is located between the third air inlet 25 and the centrifugal fan 6. The compressor 8, the condenser 7 and the evaporator 3 are connected to form a refrigerant circulation loop.

[0056] The first baffle 9 is installed in the exhaust passage 13 and is located between the centrifugal fan 6 and the third air outlet 26. The first baffle 9 is used to control the opening or closing of the exhaust passage 13. In this way, when exhaust is not required, the first baffle 9 can be controlled to close the exhaust passage 13 to prevent air leakage inside the housing 2, thereby ensuring efficient operation in other operating modes.

[0057] The second baffle 10 is installed in the air purification passage 12 and is located between the centrifugal fan 6 and the second air outlet 24. The second baffle 10 is used to control the conduction or closing of the air purification passage 12. In this way, when air purification is not required, the second baffle 10 can be controlled to close the air purification passage 12 to prevent air leakage inside the housing 2, thereby ensuring that other operating modes can be carried out efficiently.

[0058] The combination of the first baffle 9 and the second baffle 10 enables the mobile air conditioner 1 to switch between the cooling mode and the indoor air purification mode.

[0059] For details, please refer to Figure 7 The process of indoor air being discharged to the outside through the exhaust channel 13: first, the first baffle 9 is controlled to open the exhaust channel 13, and the second baffle 10 is controlled to close the air purification channel 12, that is, the second air inlet 23 is closed, and then the centrifugal fan 6 is started, and the indoor air passes through the third air inlet 25, flows through the condenser 7, and flows into the centrifugal fan 6, and is discharged to the outside from the third air outlet 26 and the connecting pipe under the drive of the centrifugal fan 6.

[0060] At the same time, the process of cooling the indoor air through the refrigeration channel 11 is as follows: first, the cross-flow fan 4 is started, and the indoor air flows from the first air inlet 21, passes through the evaporator 3, and then flows into the cross-flow fan 4. Finally, driven by the cross-flow fan 4, the indoor air flows from the first air outlet 22 on the top surface of the shell 2 to the room, realizing the cooling mode.

[0061] For details, please refer to Figure 8 , the process of purifying the indoor air through the air purification channel 12: first, control the first baffle 9 to close the exhaust channel 13, that is, the third air inlet 25 is closed, and the second baffle 10 conducts the air purification channel 12. Then, start the centrifugal fan 6, and the indoor air flows in from the second air inlet 23, passes through the filter 5 for filtering and purification, and finally flows into the room from the second air outlet 24 on the top surface of the shell 2, realizing the indoor air purification mode.

[0062] The mobile air conditioner 1 provided by the embodiment of the present invention has the following beneficial effects:

[0063] 1. Install a cross-flow fan 4 in the cooling channel 11 to blow air into the room to regulate the indoor temperature. This increases the air outlet area, achieves a longer air supply distance, increases the air supply range, and improves the efficiency of regulating the indoor air temperature.

[0064] 2. An air purification channel 12 is added, and a centrifugal fan 6 is installed in the air purification channel 12, which can provide a large air volume to the room, has a good air purification effect on the room, and improves the cleanliness of the indoor air;

[0065] 3. A first baffle 9 and a second baffle 10 are provided to realize switching of the internal air duct, so that the centrifugal fan 6 is used not only in the exhaust channel 13, but also in the air purification channel 12. That is to say, the exhaust channel 13 and the air purification channel 12 share one centrifugal fan 6, which simplifies the structure and reduces the cost.

[0066] In other embodiments, the air purification channel 12 can also be changed into a fresh air channel, that is, an air duct connected to the outside is connected to the air inlet of the air purification channel 12. In this way, the exhaust channel 13 and the fresh air channel share a centrifugal fan 6, which also simplifies the structure and reduces costs.

[0067] Although the present invention is disclosed as above, the present invention is not limited thereto.
