Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioners, in particular to a portable air conditioner. Background Art

[0002] With the improvement of living standards, air conditioning equipment is now installed in every home. In high or low temperature environments, air conditioning can be used to achieve corresponding cooling and heating operations to ensure a comfortable and suitable temperature environment for users.

[0003] When people go outdoors, existing air conditioners are too large to be carried around. Currently, mainstream outdoor air conditioners use similar portable fans to achieve corresponding auxiliary cooling operations. However, the fan itself drives the air flow to generate wind for cooling. When the outdoor temperature is high, the flowing wind itself has temperature, resulting in a not very obvious cooling effect. In addition, the fan can only be used in summer, which fails to provide users with the best use effect and still has limitations. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the utility model aims to provide a portable air conditioner.

[0005] The technical solution adopted by the utility model is as follows: a portable air conditioner, including a shell formed by assembling a front cover and a rear cover, wherein an air distribution component, a PCB main board, and an exhaust member and a refrigeration component electrically connected to the PCB main board are arranged in the shell, wherein the refrigeration component includes a semiconductor refrigeration sheet and a cooling aluminum sheet arranged above the exhaust member, wherein the cooling aluminum sheet is bonded to the cooling end surface of the semiconductor refrigeration sheet, and a cold air outlet is opened on the outer end wall of the front cover, and the air drawn in by the exhaust member is cooled by the refrigeration assembly and discharged through the cold air outlet.

[0006] In a preferred embodiment, the air distribution assembly includes an air outlet diverter plate, a cold air guide plate and a hot air guide plate. The air outlet diverter plate is installed in the air outlet end of the exhaust member and is separated to form two air outlets. The semiconductor refrigeration plate is installed at the central axis of the upper end surface of the air outlet diverter plate.

[0007] In a preferred embodiment, the cold air guide plate and the hot air guide plate are respectively surrounded by the front cover and the rear cover to form a cold air channel and a hot air channel, and a hot air outlet is opened on the end wall of the rear cover, and the hot air outlet and the cold air outlet are respectively connected to the cold air channel and the hot air channel.

[0008] In a preferred embodiment, a heat dissipation aluminum sheet is bonded to the heating end surface of the semiconductor refrigeration sheet, and the heat dissipation aluminum sheet and the cooling aluminum sheet are respectively located directly below the cold air channel and the hot air channel.

[0009] In a preferred embodiment, a display screen and a charging port are integrated on the PCB main board, and slots for embedding the display screen and the charging port are respectively provided on the outer end surfaces of the front cover, and a control button is half-embedded on the outer end surface of the front cover in front of the PCB main board.

[0010] In a preferred embodiment, the air suction member is a turbo fan, and the outer end surface of the front cover is further provided with an air inlet connected to the air inlet end of the air suction member.

[0011] In a preferred embodiment, a lithium battery electrically connected to the PCB mainboard is also provided in the housing.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0013] 1. In the utility model, a built-in semiconductor refrigeration sheet is used as a cooling / heating element. Since the temperatures at both ends of the semiconductor refrigeration sheet are opposite, the heating and cooling operations of the air can be realized at the same time. While ensuring the overall compact structure, it can also be used in different temperature environments, and has stronger applicability. Moreover, the hot air and cold air blown out are different from the outdoor temperature, and the use effect is better;

[0014] 2 In the utility model, special hot air and cold air ducts separated by air distribution components are designed on both sides of the refrigeration plate, which can greatly reduce the overall volume and weight, and can facilitate the overall carrying. In addition, the whole has a built-in rechargeable battery and can be used on the go. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] It should be mentioned that when used as a refrigeration component, the hot air exhaust part can also serve as the heat dissipation part of the semiconductor refrigeration plate 7 itself, thereby ensuring the normal operation of the semiconductor refrigeration plate 7.

[0022] Furthermore, the air distribution component includes an air outlet diverter plate 14, a cold air guide plate 4 and a hot air guide plate 13. The air outlet diverter plate 14 is installed in the air outlet end of the exhaust member 9 and is separated to form two air outlets. The semiconductor refrigeration plate 7 is installed at the central axis of the upper end surface of the air outlet diverter plate 14. The cold air guide plate 4 and the hot air guide plate 13 are respectively surrounded by the front cover 1 and the rear cover 11 to form a cold air channel and a hot air channel. A hot air outlet 111 is opened on the end wall of the rear cover 11. The hot air outlet 111 and the cold air outlet 101 are respectively connected to the cold air channel and the hot air channel. Special hot air and cold air ducts separated by the air distribution component are designed on both sides of the semiconductor refrigeration plate 7, which can greatly reduce the overall volume and weight and facilitate the overall carrying.

[0023] Furthermore, a heat dissipation aluminum sheet 12 is bonded to the heating end surface of the semiconductor refrigeration sheet 7. The heat dissipation aluminum sheet 12 and the cooling aluminum sheet 3 are respectively located directly below the cold air channel and the hot air channel. The heat at the heating end of the semiconductor refrigeration sheet 7 can be exported through the heat dissipation aluminum sheet 12.

[0024] The heat dissipating aluminum sheet 12 and the cooling aluminum sheet 3 are fixed on the semiconductor cooling sheet 7 by means of heat conductive adhesive.

A control button 2 is semi-embedded on the outer end surface of the front cover 1 in front of the PCB main board 5. A lithium battery 10 electrically connected to the PCB main board 5 is also provided in the shell 100. The lithium battery 10 can provide a power source for the entire device. When the power is insufficient, the lithium battery 10 can be charged through the charging interface 6 to meet subsequent repeated use.

[0026] Among them, the display screen 8 and the charging interface 6 are preferably an LED display screen and a Type interface respectively, but are not limited to the above types.

[0027] In addition, the control button 2 includes a switch button and a wind speed adjustment button, wherein the adjustment of the wind speed is a commonly used technology in the prior art and will not be described in detail here.

[0028] Furthermore, the air exhaust member 9 is a turbofan, and the outer end surface of the front cover 1 is also provided with an air inlet 102 connected to the air inlet end of the air exhaust member 9. The turbofan has a stronger wind force than a traditional fan, so that the subsequent exhaust wind force can be stronger, which can achieve rapid cooling and heating.
