  A display unit is provided on the door 2, and a design plate 20 is attached to the surface 2 a of the door 2. Further, the display substrate 21 and the substrate cover 22 of the display unit are provided on the back surface 2b of the door 2, and when the door 2 is closed, these are positioned above the upper portion 3b of the tank 3, and the main body. It is accommodated in a space between the casing 1 and the door 2. The space provided on the main casing 1 side is a recess 131 provided in the lower portion of the housing case 130 of the power supply substrate 13, and the substrate cover 22 provided on the back surface 2 b of the door 2 in the recess 131. Is housed.

  As shown in FIGS. 6 and 7, the door 2 has a door upper end surface 200a, a door left end surface 200b (left side as viewed from the front 2a side of the door 2), a door right end surface 200c (door) along the four sides of the back surface 2b. 2 on the right side when viewed from the front surface 2a side, and a door end surface 200 including a door lower end surface 200d is formed. Further, on the rear surface 2b of the door 2, an upper partition plate 201a and a left partition plate 201b (viewed from the front 2a side of the door 2) are located below the upper end portion of the door 2 protruding further toward the main casing 1 than the door end surface 200. Left side) and a right partition plate 201c (right side as viewed from the front surface 2a side of the door 2). The lower ends of the left partition plate 201b and the right partition plate 201c are bent to the opposite sides to form bent pieces 201d and 201e. The upper partition plate 201a is located slightly lower than the door upper end surface 200a. When the door 2 is closed, the upper partition plate 201a serves as a boundary and the upper side covers the front surface 16a of the operation case 16, and the lower The side covers the front of the tank 3.

An upper bearing 23a is provided on the left side (left partition plate 201b side) of the upper partition plate 201a of the door 2, and a lower bearing 23b is provided on the bent piece 201d on the lower side of the left partition plate 201b. 23a and 23b engage with the upper shaft 18a and the lower shaft 18b of the main casing 1, and the door 2 is pivotally supported so as to be freely opened and closed.
The upper shaft 18a (FIGS. 9 to 11) is formed by resin molding, and includes a pipe-like hollow portion 180 and an upper claw portion 181. The claw portion 181 is engaged with an attachment portion 15a provided on the board box 15. It is installed so that it does not rotate together. The lower shaft 18b is screwed to the water tray guide 19 at the lower part of the main casing 1 from the bottom.
The display substrate 21 and the operation substrate 14 are connected by a signal line 24 that is wired on the back surface 2b of the door 2 and passes through the hollow portion 180 of the upper shaft 18a.

  On the right side of the door 2 (right side when viewed from the front 2a side of the door 2), a latch portion (not shown) is provided for connecting the door 2 and the main body casing 1 when the door 2 is closed. It connects with a handle 1 a attached to the casing 1.

Next, the operation of the present embodiment configured as described above will be described with reference to FIG.
When the operation switch of the operation panel 17 is turned on, the fan motor 8 is driven, and thereby the sirocco fan 9 for intake and exhaust is rotated. In this way, indoor air is sucked from the filter cover 5, passes through the deodorizing filter 6 and the air purifying filter 7, and is deodorized and cleaned. The air introduced from the upper part is directly guided to the sirocco fan 9 in a dry state, and the air introduced from the lower part passes through the vaporization filter 10 and is guided to the sirocco fan 9 through the air passage 11. At this time, the vaporizing filter 10 sucks moisture from the water receiving tray 4, and the sucked moisture is vaporized by the air that has passed through the vaporizing filter 10, and humidifies the passing air. Thus, the clean air guided to the sirocco fan 9 is mixed here and discharged into the room from the air outlet 100 at the top of the main casing 1.

  In operation, the fan speed is automatically controlled by the power supply board 13 based on the detection mode detected by the dust sensor, odor sensor, and humidity sensor attached to the main body casing 1 and the fixed mode that rotates at the fixed fan speed. The detection state of the dust sensor and the odor sensor is indicated by a dot display, and the detection state of the humidity sensor is a digital display of the relative humidity on the display board 21 and the operation display through the design board 20 of the door 2. Is confirmed.

  When opening the door 2, the handle 2 a is lifted from the main casing 1 by pushing the handle 1 a and releasing the coupling between the door 2 and the latch portion. When the door 2 is pulled and pulled forward, the door 2 rotates around the upper shaft 18a and the lower shaft 18b located on the left side of the door 2 and moves forward. When closing the door 2, the right side of the door 2 is pressed against the main body casing 1, and the latch portion is joined. As a result, the substrate cover 22 on the back surface 2 b of the door 2 is accommodated in the recess 131 that is a space located above the tank 3.

  According to the present embodiment, since the door 2 is provided with the display unit that displays the driving state and the indoor environmental state, the visibility can be improved. Further, since the space 131 is provided on the upper side of the tank 3 of the main casing 1 and the display portion is accommodated in the space 131 when the door 2 is closed, the thickness of the main casing 1 is not increased. , Miniaturization and weight reduction can be achieved. Further, the upper bearing 23a formed on the door 2 is disposed below the upper end of the door 2 so that the upper surface of the operation case 16 and the upper end surface 200a of the door 2 are at the same height. The front surface of the operation case 16 is covered with the door 2, and therefore, no boundary line is formed between the lower surface of the operation case 16 and the upper end surface of the door 2, and a humidified air cleaner excellent in design is obtained. be able to.
