Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the utility model.

As shown in fig. 1 and 2, fig. 1 and 2 show an integrated air conditioner 1 according to the present embodiment. The integrated air conditioner 1 may be a mobile air conditioner. The integrated air conditioner 1 includes a body 2. The body 2 is generally disposed indoors.

The body 2 includes a cabinet 21, a first fan 22, a first heat exchanger, and an air filter 23. The cabinet 21 is provided with an air inlet 213 and an air outlet 212. The intake opening 213 is used to intake indoor air, and the outlet opening 212 is used to discharge the indoor air entering the body from the intake opening 213.

The first fan 22 and the first heat exchanger are both disposed in the cabinet 21. The first fan 22 can drive indoor air to enter the cabinet 21 from the air inlet 213 of the cabinet 21, pass through the first heat exchanger, and then be output from the air outlet 212 of the cabinet 21. When passing through the first heat exchanger, the indoor air exchanges heat with the first heat exchanger, so that the air output from the air outlet 212 of the cabinet 21 is hot air or cold air.

As shown in fig. 3-5, the first fan 22 includes a volute 221 and a crossflow wind wheel. An air supply flow passage 222 is provided in the volute 221. One end of the air supply channel 222 is connected to the air outlet 212 of the chassis 21. The cross flow wind wheel is disposed in the volute 221 and located at the other end of the air supply flow channel 222. The cross-flow wind wheel can rotate around the axis of the cross-flow wind wheel. When the cross flow wind wheel rotates, indoor air sucked from the air outlet 212 of the casing 21 is input to the air supply flow passage 222, and then is output to the outside of the casing 21 through the air supply flow passage 222 and the air outlet 212 of the casing 21.

As shown in fig. 5 and 6, the air filter 23 is a device for collecting dust from a gas-solid two-phase flow by the action of a porous filter material and purifying the gas. The air filter 23 is provided in the air flow passage 222, and the air filter 23 abuts against the inner peripheral wall of the air flow passage 222. The air output from the air supply flow passage 222 must flow through the air filter 23. The air filter 23 is used to filter the air flowing through the supply flow path 222. The air filter 23 has relatively small pores and dust particles, typically larger than 5 microns, cannot pass through the air filter 23.

Since the air filter 23 is disposed in the air supply flow passage 222, when the first fan 22 supplies air to the outside through the air supply flow passage 222, the air filter 23 can filter most foreign matters and dust. Even if foreign matter, such as insects, in the body 2 enters the air supply flow path 222, the foreign matter is blocked by the air filter 23 and cannot be blown out from the air supply flow path 222. When a foreign object falls into the air supply flow channel 222 from the air outlet 212, the air filter 23 prevents the foreign object from continuing to fall into the deeper part of the volute 221 to contact with a moving component (such as a cross-flow wind wheel), so as to prevent the air conditioner from generating abnormal noise. The air filter 23 also filters a portion of smoke and bacteria to make the indoor air fresher.

In one exemplary embodiment, Air Filter 23 is a High Efficiency Air Filter (High Efficiency Particulate Air Filter). The high-efficiency air filter usually adopts superfine glass fiber paper as a filter material. The high-efficiency air filter is used for trapping particulate matters with the diameter of more than 0.3 micron, and the removal efficiency of the particulate matters with the diameter of more than 0.3 micron can reach more than 99.97 percent. The effective rate of the high-efficiency air filter for 0.1 micron and 0.3 micron reaches more than 99.7 percent. High efficiency air filters are the most effective filtration media for contaminants such as smoke, dust, and bacteria.
