Problems solved by technology

[0004] However, the existing drain pan antibacterial technology described in the above-mentioned Patent Document 1 etc. has the following problems, that is, since the capacity of the antibacterial agent is initially determined, the antibacterial effect is lost after the initial capacity of the antibacterial agent is dissolved, Causes bacteria to multiply in the drain pan, thereby clogging the drain pan
[0005] Also, there is a problem that the antibacterial agent is not effective against all the bacteria present in the drain pan, there are bacteria that are not effective against it originally, or bacteria resistant to the antibacterial agent are produced after a period of time

no. 1 approach

[0023] First, the definition of the air conditioner of this embodiment is demonstrated. The air conditioner of this embodiment is an air conditioner provided with a heat exchanger, a drain pan for receiving condensed water generated in the heat exchanger, and a drain pump for discharging water accumulated in the drain pan. Specifically, there are ceiling-embedded air conditioners (with a decorative panel and the decorative panel is exposed indoors and a form in which the entire body is placed in the ceiling), a ceiling-suspended air conditioner with a drain pump installed as an option, and Wall-mounted air conditioners, etc.

[0024] The present embodiment will be described below taking a ceiling-embedded air conditioner (a form having a decorative panel and the decorative panel is exposed indoors) as an example.

[0025] Figure 1 to Figure 9 is a drawing showing the first embodiment, figure 1 It is a perspective view of a state in which the ceiling-embedded air conditione...

no. 2 approach

[0080] In the above-mentioned first embodiment, the high-voltage electrode 2a and the ground electrode 2b of the sterilizer 1 are installed in the drain pump 4, which is based on the premise that it is installed in the ceiling-embedded air conditioner 100 from the beginning. Next, A description will be given of a second embodiment assuming post-installation from the outside of the ceiling-embedded air conditioner 100 .

[0081] Figure 10 It is a drawing which shows the installation method of post-installation of the discharge electrode 2 etc. to the ceiling-embedded air conditioner 100.

[0082] Such as Figure 10 As shown, on the outer metal plate 9 of the housing 20 composed of the outer metal plate 9 of the ceiling-embedded air conditioner 100 and the heat insulating material 10, an installation hole 13 is opened on site, and the The discharge electrode 2 supported by the electrode mounting member 12 .

[0083] The electrode installation member 12 is fixed to the outer ...

no. 3 approach

[0086] In the above-mentioned first and second embodiments, the high-voltage electrode 2a and the ground electrode 2b are formed into separate structures molded by molding resins 2a-2, 2b-2, respectively, but the following structures may also be formed. , On the basis of ensuring the shortest distance of creeping discharge, only the front end of the electrode is separated, and the high withstand voltage wire 2a-3 and the side of the wire 2b-3 are integrated.

[0087] Figure 11 It is a figure which shows the discharge electrode 2 which integrated the high voltage electrode 2a and the ground electrode 2b.

[0088] Such as Figure 11 As shown, the surroundings of the electrode 2a-1 of the high-voltage electrode 2a of the discharge electrode 2 and the electrode 2b-1 of the ground electrode 2b also include the connection part with the high-voltage electric wire 2a-3 and the electric wire 2b-3, through a common Molding is performed by molding the resin 2c.

[0089] For example, ...

Abstract

The invention provides an air conditioning apparatus. An air conditioning apparatus capable of continuously sterilizing drain water in a drain pan almost permanently and thereby solving a drain pump clogging problem in any installation environment of the drain pan and in any environment where bacteria, fungi, etc. can multiply. The air conditioning apparatus may be formed to include a heat exchanger 7, a drain pan 5 receiving condensed water from the heat exchanger 7, and a drain pump 4 discharging drain water 6 from the drain pan 5. The drain pan 5 may include a sterilizing device 1. The sterilizing device 1 may include: (1) a discharge electrode 2 that is formed to include at least one pair of a high-voltage electrode 2a and a ground electrode 2b that faces the high-voltage electrode 2aat a predetermined distance; and (2) a high-voltage power supply 3 that applies high-voltage pulses to the discharge electrode 2.

Description

technical field [0001] The present invention relates to an air conditioner (indoor unit) including a heat exchanger, a drain pan for receiving drain water generated by the heat exchanger, and a drain pump for draining the drain water accumulated in the drain pan. More specifically, the present invention relates to a technique for preventing clogging of a drain pump from occurring by sterilizing bacteria or mold that cause clogging of a drain pump by discharging in drain water. Background technique [0002] In order to provide an air conditioner indoor unit capable of implementing antibacterial and antifungal measures for water guides at low cost, the following air conditioner indoor unit has been proposed that has a water guide that receives water from the front side drain pan and the rear side drain pan. The water dripped from the indoor heat exchanger is drained out of the machine through the drain pipe, and the antibacterial and antifungal materials that dissolve the anti...
