As shown in fig. 1, the fresh air conditioning indoor unit 10 according to the present invention includes a fresh air device 200 in addition to an indoor unit having the same appearance and performance as those of the prior art. Specifically, as will be understood from fig. 1 to 4, the indoor unit 10 includes a casing 100, a blower fan (not shown) and a heat exchanger 300 are disposed inside the casing 100, an air inlet 110 is opened at the top of the casing 100, and an air outlet 120 is formed at the lower part of the casing 100. Indoor air enters the indoor unit 10 from the air inlet 110 through the air supply fan, exchanges heat (for cooling or heating) through the heat exchanger 300, and then leaves the indoor unit from the air supply outlet 120. Through the mode, the temperature of the indoor air is adjusted when the ambient temperature is too low or too high, a suitable indoor environment is provided for a user, and the life quality of the user is effectively improved. The whole thickness of the fresh air device 200 is reasonably controlled within 100mm, in the embodiment, the fresh air device is about 70mm, and the requirement of fresh air change volume is met, noise is reduced as much as possible, and meanwhile, the length of the whole machine is made as short as possible, so that the manufacturing cost is reduced, and the occupied space of an indoor unit is reduced.
According to the fresh air-conditioning indoor unit 10, the fresh air device 200 is additionally arranged on the traditional air-conditioning indoor unit 10, so that in the air-conditioning refrigeration or heating process, even if an indoor window is kept closed, outdoor air can be introduced into a room through the fresh air device 200, continuous and fresh air is provided for a closed indoor space, the oxygen content of indoor air is increased, and air-conditioning diseases are avoided.
In some embodiments, as shown in fig. 1, the fresh air device 200 is disposed at one side end of the casing 100, is located inside the casing 100, and is integrated with an existing indoor unit of an air conditioner, and the fresh air device 200 is not exposed outside the indoor unit 10, so that the aesthetic appearance is maintained, and the space for installing the indoor unit 10 is saved.
Further, as can be analyzed by referring to fig. 4 and 5, the fresh air device 200 includes an air intake module 210 and a fan module 220, wherein the air intake module 210 is communicated with the fan module 220; the fan module 220 defines an air inlet chamber 211 therein, and is provided with a pipe connection 212 communicating with the air inlet chamber 211, the pipe connection 212 being for connecting a fresh air inlet pipe 213 leading to the outside.
Fig. 6 is a schematic view of a fresh air device 200 of the fresh air conditioning indoor unit 10 shown in fig. 1, and fig. 7 is a front view of the fresh air device 200 shown in fig. 4; FIG. 8 is a schematic cross-sectional view taken along section line A-A in FIG. 7; fig. 9 is a schematic cross-sectional view taken along a sectional line B-B in fig. 7.
Specifically, as shown in fig. 6 to 9 in combination, the fan module 220 includes a centrifugal fan 221 and a volute 222 disposed outside the centrifugal fan 221, an air inlet of the volute 222 is communicated with the air inlet chamber 211 of the air inlet module 210, and an air outlet 223 thereof faces the top of the casing 100, as shown in fig. 1. The centrifugal fan 221 is configured to suck air from the outdoor through the air inlet chamber 211 of the air inlet module 210, discharge the air from the air outlet 223 of the volute 222, and continuously supply fresh air from the outdoor to the indoor through the fan module 220. In the present embodiment, the air outlet 223 has a rectangular opening. The air outlet 223 and the air inlet 110 are in the same plane.
In addition, the ratio of the distance between the air outlet 223 and the air inlet 110 to the length of the air outlet 223 along the transverse direction of the casing 100 is 2: 1 to 1: 1. As shown in fig. 2 and 3, the distance between the air outlet 223 and the air inlet 110 is referred to as the distance from the edge of the air outlet 223 adjacent to the air inlet 110 to the edge of the air inlet 110 (i.e., the distance b shown in fig. 3). In the present embodiment, the distance between the air outlet 223 and the air inlet 110 is set to be 50 ± 10mm, and the length of the air outlet 223 along the transverse direction of the casing 100 (i.e., the distance a shown in fig. 3) is set to be 30 ± 10 mm. The blower fan of the indoor unit 10 is configured to suck at least a part of air discharged from the centrifugal fan 221 from the air inlet 110 at the top of the casing 100, and to discharge the air from the blower outlet 120 at the lower part of the casing 100 after exchanging heat with the heat exchanger 300. Therefore, the fresh outdoor air sent into the room can reach the indoor temperature quickly after heat exchange through the heat exchanger 300 of the indoor unit 10, so that the indoor temperature can not fluctuate greatly, the indoor temperature is kept stable, and a comfortable and healthy environment is provided for users. Through a plurality of experiments, the inventor finds that when the ratio of the distance between the air outlet 223 and the air inlet 110 to the length of the air outlet 223 along the transverse direction of the housing 100 is set within the above numerical range, more air discharged from the air outlet 223 can enter the air inlet 110.
In some preferred embodiments, the fresh air device 200 is integrally disposed at an end of the electric control board far away from the indoor unit 10, and the air intake module 210 is disposed outside the fan module 220. Because a part of the outdoor fresh air entering the room from the fan module 220 is sucked into the air inlet 110 through the air supply fan of the indoor unit 10, enters the indoor unit 10 for heat exchange, and is then sent to the room again, the fresh air device 200 is selectively installed at the side close to the air inlet 110 of the indoor unit 10 as much as possible, so that more fresh air from the outside enters the indoor unit 10, is discharged into the room after heat exchange of the indoor unit 10, more outdoor fresh air enters the indoor unit 10 for heat exchange, the fluctuation of the indoor temperature is smaller, and the indoor temperature is more stable.
Furthermore, as shown in fig. 3, the pipe connection portion 212 is disposed at the lower rear portion of the air intake module 210, and the fresh air intake pipe 213 extends out of the casing 100 along the rear side of the bottom of the casing 100 together with the pipe lines of the indoor unit 10, and the fresh air intake pipe 213 further penetrates through the wall to be led to the outdoor, so that the outdoor fresh air enters the indoor through the fresh air intake pipe 213.
Of course, in some embodiments, depending on the configuration of the indoor unit 10, the duct connection 212 may not be provided, for example, the fresh air inlet duct 213 is directly connected to the rear portion of the air inlet module 210, so as to simplify the structure of the fresh air device 200.
In other preferred embodiments, the rotational axis of the centrifugal fan 221 is parallel to the rotational axis of the supply fan. The arrangement can reduce the noise of the centrifugal fan 221, improve the working efficiency of the centrifugal fan 221 and lead more outdoor fresh air into the room. In addition, the centrifugal fan 221 is also configured such that the ratio of the rotational speed thereof to the rotational speed of the blower fan is smaller than a preset value. In the present embodiment, the preset value is set to 1, that is, the rotation speed of the centrifugal fan 221 is required to be lower than the rotation speed of the blower fan. Therefore, the wind outlet speed of the air outlet 223 is smaller, and the wind can be sucked by the air inlet 110 more easily, so that more wind sent out from the air outlet 223 enters the air inlet 110 and exchanges heat with the heat exchanger 300.
Further, as shown in fig. 1, an air outlet grille 225 corresponding to the air inlet grille of the air inlet 110 of the casing 100 is disposed at the air outlet 223 of the fan module 220. Set up air-out grid 225 in fan module 220's air outlet 223 department to prevent that dust or mosquito from getting into in new trend device 200, polluting or destroying the inner structure of new trend device 200, prevent to reduce the effect that new trend device 200 traded the new trend. The grill plates 2251 of the outlet grill 225 are inclined toward the inlet 110, so that the airflow discharged from the outlet 223 can more easily enter the inlet 110.
In order to ensure the quality of fresh air entering the room, in some embodiments, as shown in fig. 5 to 7, a filter screen 224 is detachably mounted on the air inlet side of the air inlet module 210 close to the fan module 220, and is used for filtering air delivered to the room, and the filter screen 224 and the air inlet module 210 are detachably mounted, and the filter screen 224 can be periodically detached for cleaning or replacement, so as to ensure that the air entering the room is fresh.
In other embodiments, a purification module 226 is disposed inside the outlet grill 225, and the purification module 226 uses a strong electric field dielectric technology to purify the air delivered to the room. Specifically, the purification module 226 is an FID purification device, and the FID is a dust removal technology, which is the most advanced and efficient technology in the existing dust removal technologies, and has extremely high effectiveness. A strong electric field with a dielectric material as a carrier is utilized. The dielectric material forms a honeycomb hollow micro-channel, the dielectric wrapping electrode slice forms a strong electric field in the channel, the strong electric field exerts huge attraction on charged particles moving in the air, only generates minimum air flow impedance, and can adsorb almost 100% of particles moving in the air, and the removal effect on particle pollutants such as PM2.5 and the like is particularly obvious. Adopt above-mentioned purification module 226, can reduce the PM2.5 granule in the air by a wide margin in the weather that the haze was abused, effectively improve the quality of sending into indoor outdoor air.
In addition, the purifying module 226 can also be filtered by HEPA, which is a high-efficiency filter paper and can filter 99% of fine particles in the air, so as to ensure that the air output by the fan module 220 is clean and avoid secondary pollution.
The fresh air device 200 is internally provided with the filter screen 224 and the purifying device, so that fresh air entering a room can be purified, especially, the air pollution is increasingly aggravated at present, the purified air is sent into the room, the quality of the indoor air is improved, and the harm of the polluted air to the body is reduced.
Further, the purification module 226 and the fan module 220 are detachably arranged, and the purification module 226 is placed in the groove through the groove formed in the inner side of the air outlet 223 of the fan module 220 to be installed in a matching mode. When the purification module 226 is used for a period of time, the purification module 226 can be disassembled to clean or replace the purification device, so that the quality of air purification can be ensured.
