Problems solved by technology

In this case, in the vicinity of the ceiling near the indoor unit 100, since the air discharged from the indoor unit 100 intersects the air sucked in, dust may flow to the air discharged from the indoor unit 100, and the air may not be cleaned efficiently.

[0040] figure 1 It is a perspective view which shows the appearance of the indoor unit 1 of the air conditioner of this embodiment.

[0041] figure 2 yes figure 1 A longitudinal sectional view of the indoor unit 1 of the air conditioner shown.

[0042] (Outline of indoor unit 1)

[0043] Such as figure 1 As shown, the indoor unit 1 of the air conditioner is equipped with the air guide plate 3 on the front surface of the indoor unit main body part 2 (main body part). Such as figure 2 As shown, the indoor unit main body 2 has a first suction port 12 (lower suction port) for sucking air in the lower surface, a second suction port 11 (upper suction port) for sucking air in the upper surface, and a blower fan 13 inside. And the heat exchanger 14 has an outlet 17 at the front.

[0044] In addition, the indoor unit 1 has a first filter 16 (first air cleaning filter) that purifies the passing air inside (upper side) of the first suction port 12, and has a first filter 16 (...

Deformed example 1

[0063] As mentioned above, in this embodiment, the case where the indoor unit main body part 2 has the 1st suction port 12 and the 2nd suction port 11 was demonstrated as an example. but, Figure 9 The problems described above also occur similarly when the air inlet provided with the air cleaning filter is provided only on the lower surface of the indoor unit of the air conditioner.

[0064] In addition, the indoor unit 1 is installed at a relatively high position in the air-conditioned space, such as near the ceiling. Therefore, by providing the first suction port 12 provided with the first filter 16 on the lower surface of the indoor unit 1, compared with the indoor unit of the conventional air conditioner in which the air purification filter is only provided on the upper surface of the indoor unit, , can improve the air purification effect, and can increase the intake air volume of the air.

[0065] Therefore, the present embodiment can also be applied to a case where only ...

Deformed example 2

[0067] In addition, in this embodiment, the case where the 1st filter 16 and the 2nd filter 15 are HEPA filters, for example was demonstrated as an example. However, the present embodiment is not limited thereto, the first filter 16 and the second filter 15 may be ULPA (Ultra Low Penetration Air Filter: ultra-long adjustable filter), the first filter 16 and the second filter One of the 15 can also be a HEPA filter, and the other can also be a ULPA filter. In addition, at least one of the first filter 16 and the second filter 15 may use an air cleaning filter other than a HEPA filter called a high-performance filter.

[0068] For example, the size of the dust (particle size) that can be collected by the ULPA filter is smaller than that of the HEPA filter, and the collection rate of fine dust (air cleaning rate) is high. On the other hand, the ULPA filter is more difficult for air to pass through than the HEPA filter, and the air volume is smaller. The greater the amount of su...

Abstract

An indoor unit (1) for an air conditioner has, in the lower surface of an indoor unit body part (2), a first suction port (12) provided with a first filter (16). Respective ends (12a, 16a), of the first suction port (12) and the first filter (16), on the front surface side of the indoor unit body part (2) are inclined so as to be positioned to be higher than respective ends (12b, 16b) on the rearsurface side of the indoor unit body part (2).

Description

technical field [0001] The invention relates to an air conditioner with air purification function. Background technique [0002] Conventionally, in order to obtain an air purification function, there is known an air conditioner provided with an air purification filter such as a HEPA filter (High Efficiency Particulate Air Filter: High Efficiency Air Filter) at an air intake port. The indoor unit of a general air conditioner that does not have an air cleaning function has an air intake port only on the upper surface. Therefore, the indoor unit of the air conditioner equipped with the air-cleaning filter generally has an air suction port only in the upper surface. [0003] Figure 7 (a) and (b) are explanatory diagrams which show the airflow in the air-conditioning space of the indoor unit 100 of the air conditioner which has an air-cleaning filter on the upper surface, and has an air suction port. In such an indoor unit 100, as Figure 7 As indicated by the arrow in (a), it...
