BACKGROUND OF THE INVENTION
The present invention relates to a humidifier that humidifies a room by generating air containing water vapor or moisture.
[0002]
[Prior art]
FIG. 5 is a cross-sectional view showing a conventional humidifier, in which 1 is a main body case and 2 is a partition wall for partitioning the inside of the main body case 1. In the main body case 1, a water tank 5, a steam guide tube 6, a heater 7, a steam pan 8, and the like are accommodated. 9 is a board on which switches, lamps, buzzers, etc. for operating and displaying the apparatus are mounted, and 10 is provided at the lower part of the main body case 1, and the push button portions of some switches and the condensing portions of the display lamps are integrally formed. The operation panel 11 is provided on the substrate 9, the operation switch protrudes outside the body case 1 from the hole 10 b provided in the operation panel 10, 12 is a control board on which a microcomputer or the like is mounted, and 13 is the control board 12. A control board case 14 incorporated inside is a bottom plate that forms the bottom of the main body case 1, and the control board case 13 is fixed thereto.
[0003]
In the conventional humidifier, since the operation panel 10 provided between the main body case 1 and the substrate 9 is located below the partition wall 2 of the main body case 1, the control substrate case 13 in which the control substrate 12 is incorporated. And the operation panel 10 are arranged side by side.
[0004]
[Problems to be solved by the invention]
The conventional humidifier as described above is difficult to operate when placed on a low place such as a floor or a low table, because the operation panel 10 is located at the bottom of the main body case 1, and lamps for operating conditions, current humidity, etc. There was a problem that it was difficult to see the display.
[0005]
In order to solve the above problems, the operation panel may be attached to the upper part of the main body case, and the control board case may be arranged at the lower part of the operation panel in order to make the apparatus compact. When water is applied to the front of the humidifier, water enters from the gap between the main unit case and the operation panel or the switch hole formed in the operation panel. There is a problem that water may drip into the case and water may enter the control board case.
[0006]
The present invention has been made to solve the above-described problems, and even if water enters from the gap between the main body case and the operation panel or the switch hole of the operation panel, the water will enter the control board case. It aims to provide a humidifier that prevents intrusion.
[0007]
[Means for Solving the Problems]
The humidifier according to the present invention has a main body case and a partition wall that partitions the inside of the main body case into an upper chamber and a lower chamber, and a water tank and a steam guide tube are accommodated in the upper chamber, and the lower chamber In a humidifier containing an evaporating dish or the like, a substrate on which an operation switch and a display lamp are mounted, an operation panel to which the substrate is attached and disposed along the front upper side wall of the main body case, A mounting portion extending downward from a position at which the substrate is attached to the lower back of the operation panel, a control board provided in the lower chamber and equipped with a microcomputer or the like, and a control board incorporating the control board and a case, the mounting portion of the operation panel, the lowest end are inclined arranged so as to project forwardly of the control board case, on the back bottom of the operation panel, the control group It is provided with a rib serving as a positioning when fixing the casing.
[0008]
In addition, a rib for positioning when the control board case is fixed is provided at the lower back of the operation panel.

DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1 FIG.
1 is a cross-sectional view of a humidifier showing Embodiment 1 of the present invention, FIG. 2 is an enlarged view near an operation switch, FIG. 3 is a front view of an operation panel, and FIG. 4 is a perspective view as seen from the back of the operation panel. is there. In the figure, 1 is a main body case, and 2 is a partition wall that partitions the inside of the main body case 1 into an upper chamber 3 and a lower chamber 4. The upper chamber 3 accommodates a water tank 5 and a steam guide tube 6, and the lower chamber 4 accommodates a heater 7, a steam pan 8, and the like. 9 is a board on which switches, lamps, buzzers and the like for operating and displaying are mounted, 10 is an operation panel provided along the front upper side wall of the main body case 1 and the board 9 is attached to the back side. The push button portion of the switch and the light condensing portion of the lamp are integrally formed. Reference numeral 10a denotes an attachment portion formed in the lower portion of the operation panel 10, and extends downward from a position where the substrate 9 is attached. Reference numeral 10 b denotes a hole formed in the operation panel 10, and 11 denotes an operation switch provided in the substrate 9 and protruding outside the main body case 1 from the hole 10 b. Reference numeral 12 denotes a control board provided in the lower chamber 4 and on which control parts such as a microcomputer are arranged. Reference numeral 13 denotes a control board case in which the control board 12 is incorporated. Reference numeral 14 denotes a bottom part of the main body case 1. 13 is a fixed base plate. Reference numeral 15 denotes a pair of mounting columns provided at the bottom of the back surface of the mounting portion 10a, 16 denotes ribs provided on the top and bottom of the column 15, and 17 denotes screws for fixing the pair of columns 15 to the partition wall 2. Reference numeral 18 denotes a panel attachment portion provided in the main body case 1, and 19 denotes a grip portion formed on the attachment portion 10a.
[0010]
Next, a method for attaching the operation panel 10 to the main body case 1 will be described.
First, the substrate 9 is set on the back surface of the operation panel 10. Next, the operation panel 10 on which the substrate 9 is set is inserted into the main body case 1. When the operation panel 10 is stored in the main body case 1, the positions of the push button portion and the lamp condensing portion formed integrally with the operation panel 10 are in the through holes formed in the panel mounting portion 18 of the main body case 1. And the support column 15 formed on the mounting portion 10a of the operation panel 10 contacts the lower surface of the partition wall 2. In this state, the support column 15 is fixed to the partition wall 2 with screws 17, and the operation panel 10 is attached to the main body case 1. The operation panel 10 is attached to the main body case 1 with the operation surface inclined so that the operation surface faces upward.
The operation panel 10 has a grip 19 and can be screwed to the main body case 1 to improve assembly.
